+Privoxy is based in part on code originally developed by Junkbusters Corp. and
+Anonymous Coders.
+
+Privoxy heavily relies on Philip Hazel's PCRE.
+
+The code to filter compressed content makes use of zlib which is written by
+Jean-loup Gailly and Mark Adler.
+
+On systems that lack snprintf(), Privoxy is using a version written by Mark
+Martinec. On systems that lack strptime(), Privoxy is using the one from the

+ChangeLog for Privoxy
+--------------------------------------------------------------------
+*** Version 3.0.12 (UNRELEASED) ***
+
+- The socket-timeout option now also works on platforms whose
+ select() implementation modifies the timeout structure.
+ Previously the timeout was triggered even if the connection
+ didn't stall. Reported by cyberpatrol.
+- The Connection: keep-alive code properly deals with files
+ larger than 2GB. Previously the connection was closed too
+ early.
+- The content length for files above 2GB is logged correctly.
+- The user-manual directive on the show-status page links to
+ the documentation location specified with the directive,
+ not to the Privoxy website.
+- When running in daemon mode, Privoxy doesn't log anything
+ to the console unless there are errors before the logfile
+ has been opened.
+- The show-status page prints warnings about invalid directives
+ on the same line as the directives themselves.
+- Fixed several justified (but harmless) compiler warnings,
+ mostly on 64 bit platforms.
+- The mingw32 version explicitly requests the default charset
+ to prevent display problems with some fonts available on more
+ recent Windows versions. Patch by Burberry.
+- The mingw32 version uses the Privoxy icon in the alt-tab
+ windows. Patch by Burberry.
+- The timestamp and the thread id is omitted in the "Fatal error"
+ message box on mingw32.
+- Fixed two related mingw32-only buffer overflows. Triggering
+ them required control over the configuration file, therefore
+ this isn't seen as a security issue.
+- In verbose mode, or if the new option --show-skipped-tests
+ is used, Privoxy-Regression-Test logs skipped tests and the
+ skip reason.
+
+*** Version 3.0.11 ***
+
+- On most platforms, outgoing connections can be kept alive and
+ reused if the server supports it. Whether or not this improves
+ things depends on the connection.
+- When dropping privileges, membership in supplementary groups
+ is given up as well. Not doing that can lead to Privoxy running
+ with more rights than necessary and violates the principle of
+ least privilege. Users of the --user option are advised to update.
+ Thanks to Matthias Drochner for reporting the problem,
+ providing the initial patch and testing the final version.
+- Passing invalid users or groups with the --user option
+ didn't lead to program exit. Regression introduced in 3.0.7.
+- The match all section has been moved from default.action
+ to a new file called match-all.action. As a result the
+ default.action no longer needs to be touched by the user
+ and can be safely overwritten by updates.
+- The standard.action file has been removed. Its content
+ is now part of the default.action file.
+- In some situations the logged content length was slightly too low.
+- Crunched requests are logged with their own log level.
+ If you used "debug 1" in the past, you'll probably want
+ to additionally enable "debug 1024", otherwise only passed
+ requests will be logged. If you only care about crunched
+ requests, simply replace "debug 1" with "debug 1024".
+- The crunch reason has been moved to the beginning of the
+ crunch message. For HTTP URLs, the protocol is logged as well.
+- Log messages are shortened by printing the thread id on its
+ own (as opposed to putting it inside the string "Privoxy()").
+- The config option socket-timeout has been added to control
+ the time Privoxy waits for data to arrive on a socket.
+- Support for remote toggling is controlled by the configure
+ option --disable-toggle only. In previous versions it also
+ depended on the action editor and thus configuring with the
+ --disable-editor option would disable remote toggling support
+ as well.
+- Requests with invalid HTTP versions are rejected.
+- The template symbol @date@ can be used to include a date(1)-like
+ time string. Initial patch submitted by Endre Szabo.
+- Responses from shoutcast servers are accepted again.
+ Problem reported and fix suggested by Stefan.
+- The hide-forwarded-for-headers action has been replaced with
+ the change-x-forwarded-for{} action which can also be used to
+ add X-Forwarded-For headers. The latter functionality already
+ existed in Privoxy versions prior to 3.0.7 but has been removed
+ as it was often used unintentionally (by not using the
+ hide-forwarded-for-headers action).
+- A "clear log" view option was added to the mingw32 version
+ to clear out all of the lines in the Privoxy log window.
+ Based on a patch submitted by T Ford.
+- The mingw32 version uses "critical sections" now, which prevents
+ log message corruption under load. As a side effect, the
+ "no thread-safe PRNG" warning could be removed as well.
+- The mingw32 version's task bar icon is crossed out and
+ the color changed to gray if Privoxy is toggled off.
+
+*** Version 3.0.10 ***
+
+- Ordinary configuration file changes no longer cause program
+ termination on OS/2 if the name of the logfile hasn't been
+ changed as well. This regression probably crept in with the
+ logging improvements in 3.0.7. Reported by Maynard.
+- The img-reorder filter is less likely to mess up JavaScript code in
+ img tags. Problem and solution reported by Glenn Washburn in #2014552.
+- The source tar ball now includes Privoxy-Log-Parser,
+ a syntax-highlighter for Privoxy logs. For fancy screenshots see:
+ http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
+ Documentation is available through perldoc(1).
+
+*** Version 3.0.9 Beta ***
+
+- Added SOCKS5 support (with address resolution done by
+ the SOCKS5 server). Patch provided by Eric M. Hopper.
+- The "blocked" CGI pages include a block reason that was
+ provided as argument to the last-applying block action.
+- If enable-edit-actions is disabled (the default since 3.0.7 beta)
+ the show-status page hides the edit buttons and explains why.
+ Previously the user would get the "this feature has been disabled"
+ message after using the edit button.
+- Forbidden CONNECT requests are treated like blocks by default.
+ The now-pointless treat-forbidden-connects-like-blocks action
+ has been removed.
+- Not enabling limit-connect now allows CONNECT requests to all ports.
+ In previous versions it would only allow CONNECT requests to port 443.
+ Use +limit-connect{443} if you think you need the old default behaviour.
+- The CGI editor gets turned off after three edit requests with invalid
+ file modification timestamps. This makes life harder for attackers
+ who can leverage browser bugs to send fake Referers and intend to
+ brute-force edit URLs.
+- Action settings for multiple patterns in the same section are
+ shared in memory. As a result these sections take up less space
+ (and are loaded slightly faster). Problem reported by Franz Schwartau.
+- Linear white space in HTTP headers will be normalized to single
+ spaces before parsing the header's content, headers split across
+ multiple lines get merged first. This should prevent problems like:
+ * letting the session-cookies-only action slip
+ some Cookies through unmodified,
+ * only suppressing the first line of a header,
+ thus creating an invalid one, and
+ * to incorrectly block headers with valid timestamps
+ that weren't properly recognized.
+ Headers that could trigger these problems are unlikely to appear
+ in "normal" web traffic, but could be intentionally generated to
+ fool some of Privoxy's header parsers.
+- Host information is gathered outside the main thread so it's less
+ likely to delay other incoming connections if the host is misconfigured.
+- New config option "hostname" to use a hostname other than
+ the one returned by the operating system. Useful to speed-up responses
+ for CGI requests on misconfigured systems. Requested by Max Khon.
+- The CGI editor supports the "disable all filters of this type"
+ directives "-client-header-filter", "-server-header-filter",
+ "-client-header-tagger" and "-server-header-tagger".
+- Fixed false-positives with the link-by-url filter and URLs that
+ contain the pattern "/jump/".
+- The less-download-windows filter no longer messes
+ "Content-Type: application/x-shockwave-flash" headers up.
+- In the show-url-info page's "Final results" section active and
+ inactive actions are listed separately. Patch provided by Lee.
+- The GNUmakefile supports the DESTDIR variable. Patch for
+ the install target submitted by Radoslaw Zielinski.
+- Embedding the content of configuration files in the show-status
+ page is significantly faster now. For a largish action file (1 MB)
+ a speedup of about 2450 times has been measured. This is mostly
+ interesting if you are using large action files or regularly use
+ Privoxy-Regression-Test while running Privoxy through Valgrind,
+ for stock configuration files it doesn't really matter.
+- If zlib support is unavailable and there are content
+ filters active but the prevent-compression action is disabled,
+ the show-url-info page includes a warning that compression
+ might prevent filtering.
+- The show-url-info page provides an OpenSearch Description that
+ allows to access the page through browser search plugins.
+- Custom client-header filters that rewrite the request line
+ incorrectly no longer cause Privoxy to crash. Reported by din_a4.
+- The obsolete kill-popups action has been removed as the
+ PCRS-based popup filters can do the same and are slightly
+ less unreliable.
+- The inspect-jpegs action has been removed.
+- The send-wafer and send-vanilla-wafer actions have been removed.
+ They weren't particular useful and their behaviour could be emulated
+ with add-header anyway.
+- Privoxy-Regression-Test has been significantly improved.
+- Most sections in the default.action file contain tests for
+ Privoxy-Regression-Test to verify that they are working as intended.
+- Parts of Privoxy have been refactored to increase maintainability.
+- Building with zlib (if available) is done by default.
+
+*** Version 3.0.8 ***
+
+- Fixed a small memory leak when listen-address only specifies the port.
+- The source tar balls now include Privoxy-Regression-Test which
+ (upon other things) can be used to automatically detect some
+ packaging problems. Packagers are welcome to give it a try.
+- Reverted a change in 3.0.7 that caused path patterns to be checked
+ even if the host pattern match already failed. While this doesn't
+ noticeable affect the performance, it makes it less likely to run
+ out of stack space with overly-complex path patterns the user might
+ have added.
+- Updated the msn, yahoo and google filters to work as advertised again.
+- The warning message shown by the show-status CGI page is easier to
+ understand. Previously it wasn't clear that the error message
+ is shown below the invalid directive. (Reported by Lee)
+- When regenerating Content-Disposition headers the more common
+ spelling is used for the name. Previously it was written without caps.
+- Less confusing log message if the content type isn't overwritten
+ because force-text-type wasn't used but the old type doesn't look
+ like content that would be filtered normally.
+- Better log messages if the user tries to execute filters that
+ don't exist.
+- Treat the non-standard Request-Range headers like standard range
+ headers and suppress them if content filtering is enabled.
+- Prevent the log messages for CONNECT requests to unacceptable
+ ports from printing the limit-connect argument as [null] if
+ limit-connect hasn't been explicitly enabled.
+- Don't disable the mingw32 log window if the logfile directive
+ isn't used. While it was an intentional change in 3.0.7 at least
+ one user perceived it as a regression and the same effect can
+ be achieved by disabling all debug directives.
+- Fixed two minor problems related to the win32 build process: a css
+ file was not being in the installer and the trustfile comment in the
+ config.txt referenced a nonexisting file
+- Minor documentation fixes.
+
+*** Version 3.0.7 Beta ***
+
+- Added zlib support to filter content with gzip and deflate
+ encoding. (Patch provided by Wil Mahan)
+- Dedicated filters and actions are used for header filtering.
+ "filter-client-headers" and "filter-client-headers" are no longer
+ supported, use server-header-filter{} and client-header-filter{}
+ instead.
+- Tags can be used to change actions based on HTTP headers.
+- New server-header filter: less-download-windows.
+- New client-header taggers: css-requests, image-requests,
+ client-ip-address, http-method, allow-post, complete-url,
+ user-agent and privoxy-control.
+- New server-header taggers: content-type and privoxy-control.
+- The forward-override{} action allows to change the forwarding
+ settings through the action files, for example based on client
+ headers like the User-Agent, or the request origin.
+- Socks errors are no longer handled by the CGI page for
+ DNS resolution failures.
+- CGI pages use favicons to signal whether they are error
+ or control pages. This is useful if you rely heavily on
+ browser tabs.
+- The show-url-info CGI page shows the forwarding settings.
+- "Crunch!" log messages (used when Privoxy answers requests
+ by itself) now also contain the reason.
+- Allow to rewrite the request destination behind the client's back.
+- Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
+- Fixes possible deadlocks and crashes on OpenBSD.
+ Patch provided by Ralf Horstmann.
+- The CGI action editor allows to edit actionfiles with previously
+ forbidden characters like dots.
+- New trust entries are saved with a comment that contains the
+ trusted referring URL (Suggested by Daniel Griscom).
+- Filter descriptions are HTML encoded automatically.
+- New config option "split-large-forms" to work
+ around a browser bug that caused IE6 and IE7 to ignore
+ the Submit button on the edit-actions-for-url CGI page.
+- New config option "allow-cgi-request-crunching" to allow
+ requests for Privoxy's CGI pages to be blocked, redirected
+ or (un)trusted like ordinary requests.
+- Empty filter files no longer interrupt the filtering process
+ prematurely and are correctly listed on the show-status CGI page.
+- New config option "accept-intercepted-requests" to combine
+ Privoxy with any packet filter to build an intercepting proxy
+ for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
+- fast-redirects{} catch redirects to https URLs as well.
+- redirect{s@foo@bar@} can be used to redirect to a rewritten
+ version of the original URL.
+- Trap unsupported gopher proxy requests.
+- Fixed a bug in the User Manual delivery on Windows
+ (mingw32 only). Images now show up correctly and HTML
+ pages are no longer padded with garbage data.
+- Fixed several minor memory leaks, most of them discovered with Valgrind.
+- Only unlink the pidfile if it's actually used.
+- Retries after connection problems with forced requests
+ aren't blocked again.
+- On Unix SIGABRT causes a core dump as expected and is no
+ longer treated as normal shutdown signal.
+- The "access denied" CGI page is more descriptive and
+ allows retries to circumvent the referrer check.
+- Updated PCRS to handle unexpected PCRE errors properly.
+ Fixed crashes that could occur if Privoxy was build
+ with external PCRE versions newer than Privoxy's internal
+ one. (Reported by Chung-chieh Shan)
+- Fixed crashes with null bytes in PCRS replacement strings
+ (Patch provided by Felix Gröbert).
+- Fixed crashes with header time randomization on mingw32.
+- The CGI style sheet is no longer delivered if the referring
+ page isn't a Privoxy CGI page. This prevents a JavaScript-based
+ Privoxy detection "attack". Note that detecting Privoxy is
+ still possible through other ways and Privoxy was never intended
+ to be invisible anyway.
+- Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
+- The show-url-info CGI page displays a warning if Privoxy
+ is currently toggled off.
+- The show-status CGI page suppresses the edit button
+ for action files if Privoxy has no write access.
+- Most CGI error pages react properly to HEAD requests.
+- Requests with RFC 3253 HTTP methods (used by Subversion)
+ are accepted. (Patch provided by Petr Kadlec)
+- New config option "templdir" to change the location
+ of the CGI templates to make sure customized templates
+ aren't "updated".
+- Better handling of "HTTP/1.1 100 Continue" responses.
+- The background of the PNG pattern is transparent.
+- Fixed XML syntax errors caused by banners-by-size and banners-by-url.
+- Fixed crashes and possible action file corruptions
+ when lines containing hashes are written through the CGI editor.
+- Supports dynamic filters which can contain variables.
+- Supports tags to change the actions based on client or server headers.
+- Incorrect actions are logged before program termination.
+- The "actionsfile" syntax in the configuration file is consistent
+ with the rest of the configuration options and requires the
+ whole file name. This is an incompatible change, if you use
+ an old configuration file you might have to append ".action"
+ to your "actionsfile" directives.
+- With the configuration file option "enforce-blocks" the
+ "go there anyway" mechanism can be disabled without recompiling
+ Privoxy.
+- More precise error messages in case of incorrect acl syntax.
+- Logs a warning if filtering is enabled but impossible due
+ to lack of zlib support or use of the prevent-compression action.
+- Less noisy handling of Cookie:" and "Connection:" headers.
+- Improved error messages in case of connection problems.
+- Fix a command-line-parsing bug that was introduced before 3.0.5
+ beta and caused Privoxy to treat the last argument as configuration
+ file if no configuration file was specified.
+- Treat unknown command line options as fatal errors instead
+ of silently ignoring them.
+- Use string functions with length checks more often.
+- Don't log CONNECT requests twice.
+- Allow to log the source address for ACL-related connection drops.
+- Don't ignore applying filters if the server didn't
+ specify a Content-Type. Bug reported by Amuro Namie.
+- Rejected CONNECT requests are logged with log level info
+ (enabled by default) and the reason for the block.
+- New command line option "--pre-chroot-nslookup hostname" to
+ intialize the resolver library before chroot'ing. On some systems this
+ reduces the number of files that must be copied into the chroot tree.
+ (Patch provided by Stephen Gildea)
+- Fix a long-standing memory corruption bug that could cause
+ Privoxy to overwrite a single byte in memory it didn't explicitly
+ allocate (but that probably was allocated anyway due to bucket size).
+- Send template-based CGI pages as HTTP/1.1 unless the client
+ asked for HTTP/1.0.
+- Let the first line in connection established responses
+ end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
+- If no log file has been specified, disable logging instead of logging
+ to stderr.
+- Don't block stderr when in daemon mode.
+- Ignore missing zero-chunks when filtering chunk-encoded content.
+ Earlier Privoxy versions would buffer and then forward the content
+ unmodified which caused some browsers to simply show empty pages.
+- Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
+- The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
+ action isn't being used has been removed.
+- Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
+ Reported by Lee.
+- Minor code clean-ups, filter and action file updates.
+ (Some of them reported by Davide Alberani, Markus Elfring,
+ Stefan Huehner and Adam Piggott)
+
+*** Version 3.0.6 ***
+
+- New content filters: no-ping, google, msn, yahoo and blogspot.
+- New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
+ and hide-tor-exit-notation.
+- The special header "X-Filter: No" now disables header filtering as well.
+- Improved the filters img-reorder, js-annoyances, webbugs,
+ banners-by-size, banners-by-link and ie-exploits to make them
+ less likely to break anything.
+- Removed outdated URL patterns in default.action and added new ones.
+- Added redirection from http://p.p/user-manual to http://p.p/user-manual/
+- Changed webinterface default values for hide-user-agent, hide-referrer
+ and set-image-blocker.
+
+*** Version 3.0.5 Beta ***
+
+- Windows version can be installed/started as a service.
+- Windows icon stays blue when Privoxy is idle, green when busy.
+- Integrated Fabian Keil's extensive patch. See:
+ http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
+ following new or significantly improved actions (among many
+ other improvements):
+
+ content-type-overwrite{}
+ crunch-client-header{string}
+ crunch-if-none-match
+ crunch-server-header{string}
+ fast-redirects{check-decoded-url}
+ filter-client-headers
+ filter-server-headers
+ force-text-mode
+ handle-as-empty-document
+ hide-accept-language{}
+ hide-content-disposition{}
+ hide-if-modified-since
+ hide-referrer{conditional-block}
+ overwrite-last-modified{}
+ redirect{URL}
+ treat-forbidden-connects-like-blocks
+
+- Standard-compliant clients are prevented from displaying cached
+ copies of Privoxy's error messages after the cause of the problem
+ has gone.
+- Improved DNS error handling.
+- Multiple filter files can now be specified in config.
+- Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
+ with the new inspect-jpegs action.
+- Removed the "arbitrary" 1000 filter limit - addresses tracker #911950
+- Thanks to Jindrich Makovicka for a race condition fix for the log
+ file. The race condition remains for non-pthread implementations.
+ Reference patch #1175720. Various other logging enhancements.
+- A pile of assorted bug fixes, memory leaks, enhancements, etc.
+- Moved Actions file reporting mechanism to SF tracker.
+- Two new options for config: enable-remote-http-toggle and
+ forwarded-connect-retries.
+- Trap unsupported FTP requests.
+- Let text/xml be filtered.
+- Numerous updates to default.action
+- Increase the compiled in limit of trusted referrers from 64 to 512
+ (for trustfile users).
+
+*** Version 3.0.3 ***
+
+- Fixed yet another two memory leaks. Process growth seems stopped now.
+- Further tightened security against malicious toggle-off links.
+- Excluded text/plain MIME types from filtering. This fixes a
+ couple of client-crashing, download corruption and
+ Privoxy performance issues, whose root cause lies in
+ web servers labelling content of unknown type as text/plain.
+- Assorted fixes for POSIX compliance, signal handling, graceful
+ termination, compiler warnings, OSX support, Win32 systray,
+ error logging, hostname wildcards, correct detection of NetBSD.
+- Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
+ including the notorious "blank page" problem.
+- Various filter improvements; most notably the unsolicited-popups
+ filter became less destructive
+- Major revamp of the actions file
+
+*** Version 3.0.2 ***
+
+- Fixed two memory leaks, one serious
+- Fixed bug in pcrs which could cause crashes with user-defined filters
+- Fixed bug in domain name matching
+- Assorted small fixes (Win32 menu, CGI URL editor, ..)
+- Added basic support for the OPTIONS and TRACE http methods
+- Added workaround for Bug in Mac OSX that made Privoxy crash occasionally
+- Refined the default action file through >400 items of user feedback
+- Filter changes:
+ - Assorted refinements, optimizations and fixes in the js-annoyances,
+ img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
+ html-annoyances, content-cookies and fun filters
+ - Replaced filter "popups" by choice between two modes:
+ - "unsolicited-popups" tries to catch only the unsolicited ones
+ - "all-popups" tries to kill them all (as before)
+ - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
+ - New filter "jumping-windows" that prevents windows from resizing
+ and moving themselves
+ - New filter "demoronizer" which fixes MS's abuse of std charsets
+ (common cases anyway).
+ - Replaced "nimda" with more general "ie-exploits" filter in which
+ all filters for exploits shall be collected
+- Improved cookie logging
+- Rewrote make install target. Added uninstall and install-strip
+ targets.
+- Fixed a potential (application-level, NOT OS-level!) security
+ problem involving remote toggling and action file manipulation
+ by mailicious websites.
+- Added ability to chroot (thanks to Sviatoslav Sviridov)
+- Added more action aliases for prehistoric action names
+- Add Slackware support to Makefile.

+- Three filters fixed (again!)
+- Assorted small fixes and doc enhancements
+
+*** Version 2.9.16 ***
+
+- Major revamp of default.action to get rid of years of cruft.
+- Same for default.filter
+- Re-design and major improvements to the CGI editor interface.
+- Address spurious 'out of memory' error due to incorrect file permissions.
+- Impose buffer limits while reading client and server headers.
+- Better memory and CPU optimization.
+- Add Conectiva Linux package.
+- user-manual directive added to config for help links from within CGI
+ editor.
+- Multiple actions files can now be specified in config.
+- Actions files are changed to: default.action, standard.action, and
+ user.action. user.action is for personal/local configuration.
+- The usual many small and miscellaneous bug and security fixes.
+
+*** Version 2.9.14 Beta ***
+
+- Fix Solaris compile problem (gateway.h and filters.h)
+- Makefile fixes for Solaris, FreeBSD (?)

+- Various other minor fixes.
+
+*** Version 2.9.13 Beta ***
+
+- *NEWS*: The project has been renamed to Privoxy! The new name is
+ reflected throughout (file locations, etc).
+- ijb.action is now default.action. re_filterfile is now
+ default.filter.
+- http://i.j.b/ is now http://p.p/
+- The 'logo' option for replacing ad iamges is removed now. 'Pattern'
+ (checkerboard) is now the default.
+- RPM spec file make over.
+
+
+*** Version 2.9.12 Beta ***
+
+- **READ**: The default listening PORT is NOW 8118!!! Changed from
+ 8000 due to conflict with NAS (Network Audio Server, whatever that
+ is.)
+- More CGI actions editor fixes and improvements.
+- Win32 command line fix ups.
+- re_filterfile now has modular sections that can be activated on a
+ per site basis. Some new goodies there too.
+- +filter now takes arguments to match FILTER sections in re_filterfile
+ for even more flexibility.
+- Added a new image blocker option: +image-blocker{pattern}, which
+ displays a checkerboard patthern and scales better than the logo.
+- PNG images will be used in place of GIF for JB built-in images
+ if configured with --enable-no-gif.
+- Clean up compiler warnings (mostly).
+- Improved handling of failed DNS lookups & diagnostics for failed bind
+ to listen socket

+- make should now abort if gmake (GNU make) not present.
+- Many other minor bugfixes
+- Start a ChangeLog :)
+
+
+
+*** Version 2.9.3 pre-Alpha Changes ***
+
+- Amiga support (completely untested by me - I don't have an Amiga)
+- "tinygif 3" support (redirects blocked images to a specified URL, so
+the browser doesn't have to load and cache many copies of the same
+image).
+- one case where there were both local and global "referrer" variables
+(yuck!) clarified by renaming the local one to "refer".
+- Fixed some places where close() was used instead of close_socket().
+Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
+- Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
+FORCE_LOAD_PREFIX. Needs fixing properly.
+- Most URLs hardcoded into Junkbuster were changed to go through a script
+e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
+The only other URLs left are the GNU GPL:
+ http://www.fsf.org/copyleft/gpl.html
+and the home page:
+ http://ijbswa.sourceforge.net/
+... and various URLs which will be intercepted by Junkbuster anyway.
+TODO: Still need to do something with the URLs in Junkbuster Corp's
+copyright/trademark notice on the bottom of the show-proxy-args page.
+- PCRE or GNU Regex is now a #define option.
+
+
+*** Version 2.9.2 pre-Alpha Changes ***
+
+- Andreas applied the latest version of the FORCE patch.
+
+
+*** Version 2.9.1 pre-Alpha Changes ***
+
+- in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
+(BTW: I think FORCE is precise enough, since loading remote
+data is the whole purpose of a proxy..)
+- Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
+is more elegant and looks like a hostname in the URL, it doesn't
+make clear to the inexperienced user that the proxy is bypassed. It
+also has a higher name collision risk.
+- Filled in the function header templates for my functions in
+parsers.c (again). They obviously got lost in our current
+patch war ;-)
+- Cut the credit for the §-referrer-option from the config file,
+that Stefan had placed there.
+- Improved the re_filterfile
+
+
+*** Version 2.9.0 pre-Alpha Changes ***
+
+- Now use PCRE, not GNU REGEX. I have not yet had chance to check the
+syntax of the block/image/cookie file to ensure that they match what
+is expected - however they seem to work.
+- Replaced "configure" script with one generated by "autoconf". Also
+use a header "config.h" (was ijbconfig.h in my previous release) for
+the #defines. "config.h" is now generated with "autoheader" from
+"acconfig.h" and "configure.in". (Note that to install you do not
+need autoconf or autoheader - just run "./configure".)
+To see command-line options, run "./configure --help".
+This is my first ever autoconf script, so it has some rough edges
+(how PCRE is handled is the roughest).
+- Error logging code replaced with new module errlog.c, based on the
+one from JunkbusterMT (but with the threading code removed).
+- Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
+apply all of these, since I had already independently done conditional
+popup file, conditional image file, and integration of popup code.
+- ACL, Jar and trust files conditionally compiled.
+- New source file headers.
+- Various cosmetic changes. (But I have not consistently ordered the
+config files - I think that's worthwhile, but it's 1am and I want to
+get this released!)
+- RCS tags on .h files.
+- RCS tags are const char[] rather than const char *. (Saves 4 bytes
+per tag ;-)
+- VC++ project files renamed to vc_junkbuster.*.
+- show-proxy-args now shows status of all conditionals, not just REGEX
+- Various functions moved around. Most notably all the system-specific
+sockets code which was spread between jcc.c, bind.c, and connect.c,
+has been moved to "jbsockets.c". The non-system-specific code from
+connect.c and socks4.c has been movet to "gateway.c". Also, the
+config file loader and the global variables it writes to have been
+moved to "loadcfg.c". (Maybe this should go into loaders.c?)
+And candidate for the "worst filename ever" award is "miscutil.c",
+which contains, well, miscellaneous utility functions like zalloc.
+(Suggestions for a better name for this file are welcome!)
+- Loaders now use a common function to read a line and skip comments,
+and this function also stores the proxy_args.
+- Added ./junkbuster --help (Not for Win32 GUI)
+- Added ./junkbuster --version (Not for Win32 GUI)
+- Win32 resources are now all marked as "U.S. English", rather than
+being a mix of "U.S. English", "U.K. English" and "Irish English".
+- Version number changes to 2.9.0

+# - TAR_ARCH = /tmp/JunkbusterNG-$(RPM_VERSION).tar.gz
+# - PROGRAM = jbng
+# - rh-spec now references as junkbusterng-rh.spec
+# - redhat-upload: references changed to junkbusterng-* (package names)

+# - junkbusterng.spec:
+# - References to the expression ijb where changed where possible
+# - New package name: junkbusterng (all in lower case, acording to
+# the LSB recomendation)
+# - Version changed to: 2.9.13
+# - Release: 1
+# - Added: junkbuster to obsoletes and conflicts (Not sure this is
+# right. If it obsoletes, why conflict ? Have to check it later)
+# - Summary changed: Stefan, please check and aprove it
+# - Changes description to use the new name
+# - Sed string was NOT changed. Have to wait to the manpage to

+# - Created JB_OBIN with the old value of JB_BIN (junkbuster), to

+#
+# Aditional notes:
+# - The config directory is /etc/junkbuster yet. Have to change it on the
+# specfile, after it is changes on the code

+# - Ongoing process to change name to JunkbusterNG
+# - configure/configure.in: no change needed
+# - GNUmakefile.in:
+# - TAR_ARCH = /tmp/JunkbusterNG-$(RPM_VERSION).tar.gz
+# - PROGRAM = jbng@EXEEXT@
+# - rh-spec now references as junkbusterng-rh.spec
+# - redhat-upload: references changed to junkbusterng-* (package names)
+# - tarball-dist: references changed to JunkbusterNG-distribution-*
+# - tarball-src: now JunkbusterNG-*
+# - install: initscript now junkbusterng.init and junkbusterng (when
+# installed)
+# - junkbuster-rh.spec: renamed to junkbusterng-rh.spec
+# - junkbusterng.spec:
+# - References to the expression ijb where changed where possible
+# - New package name: junkbusterng (all in lower case, acording to
+# the LSB recomendation)
+# - Version changed to: 2.9.13
+# - Release: 1
+# - Added: junkbuster to obsoletes and conflicts (Not sure this is
+# right. If it obsoletes, why conflict ? Have to check it later)
+# - Summary changed: Stefan, please check and aprove it
+# - Changes description to use the new name
+# - Sed string was NOT changed. Have to wait to the manpage to

+# - Keeping the user junkbuster for now. It will require some aditional
+# changes on the script (scheduled for the next specfile release)
+# - Added post entry to move the old logfile to the new log directory
+# - Removing "chkconfig --add" entry (not good to have it automaticaly

+-------------------------------------------------------------------------------
+
+To build Privoxy from source, autoconf, GNU make (gmake), and, of course, a C
+compiler like gcc are required.
+
+When building from a source tarball, first unpack the source:
+
+ tar xzvf privoxy-3.0.12-stable-src.tar.gz
+ cd privoxy-3.0.12-stable
+
+
+For retrieving the current CVS sources, you'll need a CVS client installed.
+Note that sources from CVS are typically development quality, and may not be
+stable, or well tested. To download CVS source, check the Sourceforge
+documentation, which might give commands like:
+
+ cvs -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa login
+ cvs -z3 -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa co current
+ cd current
+
+
+This will create a directory named current/, which will contain the source
+tree.
+
+You can also check out any Privoxy "branch", just exchange the current name
+with the wanted branch name (Example: v_3_0_branch for the 3.0 cvs tree).
+
+It is also strongly recommended to not run Privoxy as root. You should
+configure/install/run Privoxy as an unprivileged user, preferably by creating a
+"privoxy" user and group just for this purpose. See your local documentation
+for the correct command line to do add new users and groups (something like
+adduser, but the command syntax may vary from platform to platform).
+
+/etc/passwd might then look like:
+
+ privoxy:*:7777:7777:privoxy proxy:/no/home:/no/shell
+
+
+And then /etc/group, like:
+
+ privoxy:*:7777:
+
+
+Some binary packages may do this for you.
+
+Then, to build from either unpacked tarball or CVS source:
+
+ autoheader
+ autoconf
+ ./configure # (--help to see options)
+ make # (the make from GNU, sometimes called gmake)
+ su # Possibly required
+ make -n install # (to see where all the files will go)
+ make -s install # (to really install, -s to silence output)
+
+
+Using GNU make, you can have the first four steps automatically done for you by
+just typing:
+
+ make
+
+
+in the freshly downloaded or unpacked source directory.
+
+To build an executable with security enhanced features so that users cannot
+easily bypass the proxy (e.g. "Go There Anyway"), or alter their own
+configurations, configure like this:
+
+ ./configure --disable-toggle --disable-editor --disable-force
+
+
+Then build as above. In Privoxy 3.0.7 and later, all of these options can also
+be disabled through the configuration file.
+
+WARNING: If installing as root, the install will fail unless a non-root user or
+group is specified, or a privoxy user and group already exist on the system. If
+a non-root user is specified, and no group, then the installation will try to
+also use a group of the same name as "user". If a group is specified (and no
+user), then the support files will be installed as writable by that group, and
+owned by the user running the installation.
+
+configure accepts --with-user and --with-group options for setting user and
+group ownership of the configuration files (which need to be writable by the
+daemon). The specified user must already exist. When starting Privoxy, it must
+be run as this same user to insure write access to configuration and log files!
+
+Alternately, you can specify user and group on the make command line, but be
+sure both already exist:
+
+ make -s install USER=privoxy GROUP=privoxy
+
+
+The default installation path for make install is /usr/local. This may of
+course be customized with the various ./configure path options. If you are
+doing an install to anywhere besides /usr/local, be sure to set the appropriate
+paths with the correct configure options (./configure --help). Non-privileged
+users must of course have write access permissions to wherever the target
+installation is going.
+
+If you do install to /usr/local, the install will use sysconfdir=$prefix/etc/
+privoxy by default. All other destinations, and the direct usage of
+--sysconfdir flag behave like normal, i.e. will not add the extra privoxy
+directory. This is for a safer install, as there may already exist another
+program that uses a file with the "config" name, and thus makes /usr/local/etc
+cleaner.
+
+If installing to /usr/local, the documentation will go by default to $prefix/
+share/doc. But if this directory doesn't exist, it will then try $prefix/doc
+and install there before creating a new $prefix/share/doc just for Privoxy.
+
+Again, if the installs goes to /usr/local, the localstatedir (ie: var/) will
+default to /var instead of $prefix/var so the logs will go to /var/log/privoxy
+/, and the pid file will be created in /var/run/privoxy.pid.
+
+make install will attempt to set the correct values in config (main
+configuration file). You should check this to make sure all values are correct.
+If appropriate, an init script will be installed, but it is up to the user to
+determine how and where to start Privoxy. The init script should be checked for
+correct paths and values, if anything other than a default install is done.
+
+If install finds previous versions of local configuration files, most of these
+will not be overwritten, and the new ones will be installed with a "new"
+extension. default.action and default.filter will be overwritten. You will then
+need to manually update the other installed configuration files as needed. The
+default template files will be overwritten. If you have customized, local
+templates, these should be stored safely in a separate directory and defined in
+config by the "templdir" directive. It is of course wise to always back-up any
+important configuration files "just in case". If a previous version of Privoxy
+is already running, you will have to restart it manually.
+
+For more detailed instructions on how to build Redhat RPMs, Windows
+self-extracting installers, building on platforms with special requirements
+etc, please consult the developer manual.
+
+The simplest command line to start Privoxy is $path/privoxy --user=privoxy
+$path/etc/privoxy/config. See privoxy --usage, or the man page, for other
+options, and configuration.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+
+This README is included with Privoxy 3.0.12. See http://www.privoxy.org/ for
+more information. The current code maturity level is "stable".
+
+-------------------------------------------------------------------------------
+
+Privoxy is a non-caching web proxy with advanced filtering capabilities for
+enhancing privacy, modifying web page data and HTTP headers, controlling
+access, and removing ads and other obnoxious Internet junk. Privoxy has a
+flexible configuration and can be customized to suit individual needs and
+tastes. It has application for both stand-alone systems and multi-user
+networks.
+
+Privoxy is Free Software and licensed under the GPL2.
+
+Privoxy is an associated project of Software in the Public Interest (SPI).
+Donations are welcome.
+
+-------------------------------------------------------------------------------
+
+1. IMPORTANT CHANGES
+
+March 2009, Privoxy 3.0.12 is released.
+
+This is primarily a bug fix release. See the "ChangeLog", and the "What's New"
+section and the "Upgrader's Notes" in the User Manual for details.
+
+February 2009, Privoxy 3.0.11 is released.
+
+As usual there are changes that effect the configuration. See the "ChangeLog",
+and the "What's New" section and the "Upgrader's Notes" in the User Manual for
+details and specifics.
+
+This is a stable release, and marks a departure for Privoxy development.
+
+Previously, odd numbered releases were considered beta versions and were only
+released at the end of the development cycle when the code was already believed
+to be stable. Usually it was, so the stable release contained pretty much the
+same code, but got a higher version number. In the future we intend to release
+several snapshots between stable releases. There will probably still be about
+two stable releases per year, but hopefully about six snapshots instead of the
+two betas we have now. The intentions is to make testing without CVS access
+easier.
+
+-------------------------------------------------------------------------------
+
+2. INSTALL
+
+See the INSTALL file in this directory, for installing from raw source, and the
+User Manual, for all other installation types.
+
+-------------------------------------------------------------------------------
+
+3. RUN
+
+privoxy [--help] [--version] [--no-daemon] [--pidfile PIDFILE] [--user USER
+[.GROUP]] [--chroot] [--pre-chroot-nslookup HOSTNAME ][config_file]
+
+See the man page or User Manual for an explanation of each option, and other
+configuration and usage issues.
+
+If no config_file is specified on the command line, Privoxy will look for a
+file named 'config' in the current directory (except Win32 which will look for
+'config.txt'). If no config_file is found, Privoxy will fail to start.
+
+Or for Red Hat and Fedora based distributions: /etc/rc.d/init.d/privoxy start
+
+Or Debian and Ubuntu: /etc/init.d/privoxy start
+
+-------------------------------------------------------------------------------
+
+4. CONFIGURATION
+
+See: 'config', 'default.action', 'user.action', 'default.filter', and
+'user.filter'. 'user.action' and 'user.filter' are for personal and local
+configuration preferences. These are all well commented. Most of the magic is
+in '*.action' files. 'user.action' should be used for any actions
+customizations. On Unix-like systems, these files are typically installed in /
+etc/privoxy. On Windows, then wherever the executable itself is installed.
+There are many significant changes and advances from earlier versions. The User
+Manual has an explanation of all configuration options, and examples: http://
+www.privoxy.org/user-manual/.
+
+Be sure to set your browser(s) for HTTP/HTTPS Proxy at <IP>:<Port>, or whatever
+you specify in the config file under 'listen-address'. DEFAULT is
+localhost:8118. Note that Privoxy ONLY proxies HTTP (and HTTPS) traffic. Do not
+try it with FTP or other protocols for the simple reason it does not work.
+
+The actions list can be configured via the web interface accessed via http://
+p.p/, as well other options.
+
+-------------------------------------------------------------------------------
+
+5. DOCUMENTATION
+
+There should be documentation in the 'doc' subdirectory. In particular, see the
+User Manual there, the FAQ, and those interested in Privoxy development, should
+look at developer-manual.
+
+The source and configuration files are all well commented. The main
+configuration files are: 'config', 'default.action', and 'default.filter'.
+
+Included documentation may vary according to platform and packager. All
+documentation is posted on http://www.privoxy.org, in case you don't have it,
+or can't find it.
+
+-------------------------------------------------------------------------------
+
+6. CONTACTING THE DEVELOPERS, BUG REPORTING AND FEATURE REQUESTS
+
+We value your feedback. In fact, we rely on it to improve Privoxy and its
+configuration. However, please note the following hints, so we can provide you
+with the best support:
+
+-------------------------------------------------------------------------------
+
+6.1. Get Support
+
+For casual users, our support forum at SourceForge is probably best suited:
+http://sourceforge.net/tracker/?group_id=11118&atid=211118
+
+All users are of course welcome to discuss their issues on the users mailing
+list, where the developers also hang around.
+
+Please don't sent private support requests to individual Privoxy developers,
+either use the mailing lists or the support trackers.
+
+Note that the Privoxy mailing lists are moderated. Posts from unsubscribed
+addresses have to be accepted manually by a moderator. This may cause a delay
+of several days and if you use a subject that doesn't clearly mention Privoxy
+or one of its features, your message may be accidentally discarded as spam.
+
+If you aren't subscribed, you should therefore spend a few seconds to come up
+with a proper subject. Additionally you should make it clear that you want to
+get CC'd. Otherwise some responses will be directed to the mailing list only,
+and you won't see them.
+
+-------------------------------------------------------------------------------
+
+6.2. Reporting Problems
+
+"Problems" for our purposes, come in two forms:
+
+ * Configuration issues, such as ads that slip through, or sites that don't
+ function properly due to one Privoxy "action" or another being turned "on".
+
+ * "Bugs" in the programming code that makes up Privoxy, such as that might
+ cause a crash.
+
+-------------------------------------------------------------------------------
+
+6.2.1. Reporting Ads or Other Configuration Problems
+
+Please send feedback on ads that slipped through, innocent images that were
+blocked, sites that don't work properly, and other configuration related
+problem of default.action file, to http://sourceforge.net/tracker/?group_id=
+11118&atid=460288, the Actions File Tracker.
+
+New, improved default.action files may occasionally be made available based on
+your feedback. These will be announced on the ijbswa-announce list and
+available from our the files section of our project page.
+
+-------------------------------------------------------------------------------
+
+6.2.2. Reporting Bugs
+
+Please report all bugs through our bug tracker: http://sourceforge.net/tracker
+/?group_id=11118&atid=111118.
+
+Before doing so, please make sure that the bug has not already been submitted
+and observe the additional hints at the top of the submit form. If already
+submitted, please feel free to add any info to the original report that might
+help to solve the issue.
+
+Please try to verify that it is a Privoxy bug, and not a browser or site bug or
+documented behaviour that just happens to be different than what you expected.
+If unsure, try toggling off Privoxy, and see if the problem persists.
+
+If you are using your own custom configuration, please try the stock configs to
+see if the problem is configuration related. If you're having problems with a
+feature that is disabled by default, please ask around on the mailing list if
+others can reproduce the problem.
+
+If you aren't using the latest Privoxy version, the bug may have been found and
+fixed in the meantime. We would appreciate if you could take the time to
+upgrade to the latest version (or even the latest CVS snapshot) and verify that
+your bug still exists.
+
+Please be sure to provide the following information:
+
+ * The exact Privoxy version you are using (if you got the source from CVS,
+ please also provide the source code revisions as shown in http://
+ config.privoxy.org/show-version)
+
+ * The operating system and versions you run Privoxy on, (e.g. Windows XP
+ SP2), if you are using a Unix flavor, sending the output of "uname -a"
+ should do, in case of GNU/Linux, please also name the distribution.
+
+ * The name, platform, and version of the browser you were using (e.g.
+ Internet Explorer v5.5 for Mac).
+
+ * The URL where the problem occurred, or some way for us to duplicate the
+ problem (e.g. http://somesite.example.com/?somethingelse=123)
+
+ * Whether your version of Privoxy is one supplied by the Privoxy developers
+ via SourceForge, or if you got your copy somewhere else.
+
+ * Whether you are using Privoxy in tandem with another proxy such as Tor. If
+ so, please temporary disable the other proxy to see if the symptoms change.
+
+ * Whether you are using a personal firewall product. If so, does Privoxy work
+ without it?
+
+ * Any other pertinent information to help identify the problem such as config
+ or log file excerpts (yes, you should have log file entries for each action
+ taken).
+
+You don't have to tell us your actual name when filing a problem report, but
+please use a nickname so we can differentiate between your messages and the
+ones entered by other "anonymous" users that may respond to your request if
+they have the same problem or already found a solution.

+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.9 2001/07/29 19:08:52 jongfoster

+ *
+ * Revision 1.5 2001/07/13 13:48:37 oes
+ * - (Fix:) Copied CODE_STATUS #define from config.h.in
+ * - split REGEX #define into REGEX_GNU and REGEX_PCRE
+ * and removed PCRE.
+ * (REGEX = REGEX_GNU || REGEX_PCRE per project.h)
+ * - Moved STATIC (for pcre) here from Makefile.in
+ * - Introduced STATIC_PCRS #define to allow for dynaimc linking with
+ * libpcrs
+ * - Removed PCRS #define, since pcrs is now needed for CGI anyway
+ *
+ * Revision 1.4 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.3 2001/05/26 01:26:34 jongfoster
+ * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.
+ * This #define cannot be set from ./configure - there's no point, it
+ * doesn't work yet. See feature request # 425722
+ *
+ * Revision 1.2 2001/05/22 17:43:35 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Many minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:45 oes
+ * Initial import of version 2.9.3 source tree

+ *
+ * Revision 1.32.2.4 2003/12/03 10:33:11 oes
+ * - Implemented Privoxy version requirement through

+ * Correcting function comments
+ *
+ * Revision 1.31 2002/05/06 07:56:50 oes
+ * Made actions_to_html independent of FEATURE_CGI_EDIT_ACTIONS
+ *
+ * Revision 1.30 2002/04/30 11:14:52 oes
+ * Made csp the first parameter in *action_to_html
+ *

+ * Standardizing on no space.
+ * - Greatly simplifying some of the code by using string_join()
+ * where appropriate.
+ *
+ * Revision 1.28 2002/04/26 12:53:15 oes
+ * - CGI AF editor now writes action lines split into
+ * single lines with line continuation

+ * - Jon's patch for multiple AFs:
+ * - split load_actions_file, add load_one_actions_file

+ * Revision 1.26 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * Revision 1.25 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.24 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.23 2002/03/07 03:46:16 oes
+ * Fixed compiler warnings
+ *
+ * Revision 1.22 2002/01/21 00:27:02 jongfoster
+ * Allowing free_action(NULL).
+ * Moving the functions that #include actionlist.h to the end of the file,
+ * because the Visual C++ 97 debugger gets extremely confused if you try
+ * to debug any code that comes after them in the file.
+ *
+ * Revision 1.21 2002/01/17 20:54:44 jongfoster
+ * Renaming free_url to free_url_spec, since it frees a struct url_spec.
+ *
+ * Revision 1.20 2001/11/22 21:56:49 jongfoster
+ * Making action_spec->flags into an unsigned long rather than just an
+ * unsigned int.
+ * Fixing a bug in the display of -add-header and -wafer
+ *
+ * Revision 1.19 2001/11/13 00:14:07 jongfoster
+ * Fixing stupid bug now I've figured out what || means.
+ * (It always returns 0 or 1, not one of it's paramaters.)
+ *
+ * Revision 1.18 2001/11/07 00:06:06 steudten
+ * Add line number in error output for lineparsing for
+ * actionsfile.
+ *
+ * Revision 1.17 2001/10/25 03:40:47 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.16 2001/10/23 21:30:30 jongfoster
+ * Adding error-checking to selected functions.
+ *
+ * Revision 1.15 2001/10/14 21:58:22 jongfoster
+ * Adding support for the CGI-based editor:
+ * - Exported get_actions()
+ * - Added new function free_alias_list()
+ * - Added support for {{settings}} and {{description}} blocks
+ * in the actions file. They are currently ignored.
+ * - Added restriction to only one {{alias}} block which must appear

+ * Revision 1.14 2001/09/22 16:36:59 jongfoster
+ * Removing unused parameter fs from read_config_line()
+ *
+ * Revision 1.13 2001/09/16 15:47:37 jongfoster
+ * First version of CGI-based edit interface. This is very much a
+ * work-in-progress, and you can't actually use it to edit anything
+ * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
+ * to have any effect.
+ *
+ * Revision 1.12 2001/09/16 13:21:27 jongfoster
+ * Changes to use new list functions.
+ *
+ * Revision 1.11 2001/09/14 00:17:32 jongfoster
+ * Tidying up memory allocation. New function init_action().
+ *
+ * Revision 1.10 2001/09/10 10:14:34 oes
+ * Removing unused variable
+ *
+ * Revision 1.9 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.8 2001/06/29 13:19:52 oes
+ * Removed logentry from cancelled commit
+ *
+ * Revision 1.7 2001/06/09 10:55:28 jongfoster
+ * Changing BUFSIZ ==> BUFFER_SIZE
+ *
+ * Revision 1.6 2001/06/07 23:04:34 jongfoster
+ * Made get_actions() static.
+ *
+ * Revision 1.5 2001/06/03 19:11:48 oes
+ * adapted to new enlist_unique arg format
+ *
+ * Revision 1.4 2001/06/01 20:03:42 jongfoster
+ * Better memory management - current_action->strings[] now
+ * contains copies of the strings, not the original.
+ *
+ * Revision 1.3 2001/06/01 18:49:17 jongfoster
+ * Replaced "list_share" with "list" - the tiny memory gain was not
+ * worth the extra complexity.
+ *
+ * Revision 1.2 2001/05/31 21:40:00 jongfoster
+ * Removing some commented out, obsolete blocks of code.
+ *
+ * Revision 1.1 2001/05/31 21:16:46 jongfoster
+ * Moved functions to process the action list into this new file.

+ * as they load multiple files "now".
+ *
+ * Revision 1.17 2008/01/28 20:17:40 fabiankeil
+ * - Mark some parameters as immutable.
+ * - Hide update_action_bits_for_all_tags() while it's unused.
+ *
+ * Revision 1.16 2007/04/17 18:21:45 fabiankeil
+ * Split update_action_bits() into
+ * update_action_bits_for_all_tags()
+ * and update_action_bits_for_tag().
+ *
+ * Revision 1.15 2007/04/15 16:39:20 fabiankeil
+ * Introduce tags as alternative way to specify which
+ * actions apply to a request. At the moment tags can be
+ * created based on client and server headers.
+ *
+ * Revision 1.14 2006/07/18 14:48:45 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.12 2002/05/06 07:56:50 oes
+ * Made actions_to_html independent of FEATURE_CGI_EDIT_ACTIONS
+ *
+ * Revision 1.11 2002/04/30 11:14:52 oes
+ * Made csp the first parameter in *action_to_html
+ *
+ * Revision 1.10 2002/04/26 12:53:33 oes
+ * - actions_to_html signature change
+ * - current_action_to_text: renamed to current_action_to_html
+ * and signature change
+ *
+ * Revision 1.9 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * Revision 1.8 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.7 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.6 2001/10/23 21:30:30 jongfoster
+ * Adding error-checking to selected functions.
+ *
+ * Revision 1.5 2001/10/14 21:58:22 jongfoster
+ * Adding support for the CGI-based editor:
+ * - Exported get_actions()
+ * - Added new function free_alias_list()
+ * - Added support for {{settings}} and {{description}} blocks
+ * in the actions file. They are currently ignored.
+ * - Added restriction to only one {{alias}} block which must appear
+ * first in the file, to simplify the editor's rewriting rules.
+ * - Note that load_actions_file() is no longer used by the CGI-based
+ * editor, but some of the other routines in this file are.
+ *
+ * Revision 1.4 2001/09/16 15:47:37 jongfoster
+ * First version of CGI-based edit interface. This is very much a
+ * work-in-progress, and you can't actually use it to edit anything
+ * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
+ * to have any effect.
+ *
+ * Revision 1.3 2001/09/14 00:17:32 jongfoster
+ * Tidying up memory allocation. New function init_action().
+ *
+ * Revision 1.2 2001/07/29 19:01:11 jongfoster
+ * Changed _FILENAME_H to FILENAME_H_INCLUDED.
+ * Added forward declarations for needed structures.
+ *
+ * Revision 1.1 2001/05/31 21:16:46 jongfoster
+ * Moved functions to process the action list into this new file.

+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.5 2002/03/03 09:18:03 joergs

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ @<:@@S|@ac_default_prefix@:>@
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]

+ --disable-trust-files Prevents the use of trust files.
+ --disable-editor Prevents the use of the web-based actions file
+ editor and web-based temporary disable setting.
+ --enable-no-gifs Use politically correct PNG format instead of GIF

+ --enable-graceful-termination Allow to shutdown Privoxy through the webinterface.
+ --enable-extended-host-patterns Allow extended regular expressions in host patterns.
+ --disable-dynamic-pcre Use the built-in, static pcre, even if libpcre is available
+ --disable-zlib Don't use zlib to decompress data before filtering.
+
+Optional Packages:
+ --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
+ --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
+ --with-docbook=yes|no|directory
+ Enable docbook documentation creation
+ (default = yes, for gnu and linux)
+ --with-db2html=<path/executable>
+ Set the location of the docbook to html converter
+ (default = search)
+ --with-debug Enable debug mode
+ --with-user=privoxy Set user under which privoxy will run
+ --with-group=privoxy Set group for privoxy
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ * layer of indirection before the pthread mutex functions.
+ *
+ * Revision 1.112 2008/08/31 16:08:12 fabiankeil
+ * "View the request headers" isn't more equal than the other
+ * menu items and thus doesn't need a trailing dot either.
+ *
+ * Revision 1.111 2008/08/31 15:59:02 fabiankeil
+ * There's no reason to let remote toggling support depend
+ * on FEATURE_CGI_EDIT_ACTIONS, so make sure it doesn't.
+ *
+ * Revision 1.110 2008/08/31 14:55:43 fabiankeil
+ * Add a @date@ symbol to include a date(1)-like time string

+ * submitted in #2026468.
+ *
+ * Revision 1.109 2008/07/26 09:40:27 fabiankeil
+ * Remove the unconditional block in get_http_time().
+ * It's pointless now that it's no longer used to limit
+ * dummy's scope. While at it, remove obvious comments
+ * and a trailing space.
+ *
+ * Revision 1.108 2008/05/26 17:30:53 fabiankeil
+ * Provide an OpenSearch Description to access the
+ * show-url-info page through "search engine plugins".

+ * Revision 1.105 2008/04/17 14:40:47 fabiankeil

+ * have to blindly assume that the buffer is big enough.
+ *
+ * Revision 1.104 2008/03/26 18:07:06 fabiankeil
+ * Add hostname directive. Closes PR#1918189.
+ *
+ * Revision 1.103 2008/03/21 11:13:57 fabiankeil
+ * Only gather host information if it's actually needed.
+ * Also move the code out of accept_connection() so it's less likely
+ * to delay other incoming connections if the host is misconfigured.
+ *
+ * Revision 1.102 2008/02/23 16:33:43 fabiankeil
+ * Let forward_url() use the standard parameter ordering

+ * Add SOCKS5 support for "Forwarding failure" CGI page.

+ * Revision 1.99 2007/08/05 13:42:22 fabiankeil
+ * #1763173 from Stefan Huehner: declare some more functions static.
+ *
+ * Revision 1.98 2007/05/14 10:33:51 fabiankeil
+ * - Use strlcpy() and strlcat() instead of strcpy() and strcat().
+ *
+ * Revision 1.97 2007/04/09 18:11:35 fabiankeil
+ * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
+ *
+ * Revision 1.96 2007/03/08 17:41:05 fabiankeil
+ * Use sizeof() more often.
+ *
+ * Revision 1.95 2007/02/10 17:01:37 fabiankeil
+ * Don't overlook map result for the forwarding-type.
+ *
+ * Revision 1.94 2007/02/08 19:44:49 fabiankeil
+ * Use a transparent background for the PNG replacement pattern.
+ *
+ * Revision 1.93 2007/02/07 10:45:22 fabiankeil

+ * errors on the "blocked" template.

+ * Revision 1.90 2007/01/25 13:47:26 fabiankeil
+ * Added "forwarding-failed" template support for error_response().
+ *
+ * Revision 1.89 2007/01/23 15:51:16 fabiankeil
+ * Add favicon delivery functions.
+ *
+ * Revision 1.88 2007/01/23 13:14:32 fabiankeil
+ * - Map variables that aren't guaranteed to be
+ * pure ASCII html_encoded.
+ * - Use CGI_PREFIX to generate URL for user manual
+ * CGI page to make sure CGI_SITE_2_PATH is included.
+ *
+ * Revision 1.87 2007/01/22 15:34:13 fabiankeil
+ * - "Protect" against a rather lame JavaScript-based
+ * Privoxy detection "attack" and check the referrer
+ * before delivering the CGI style sheet.
+ * - Move referrer check for unsafe CGI pages into
+ * referrer_is_safe() and log the result.
+ * - Map @url@ in cgi-error-disabled page.
+ * It's required for the "go there anyway" link.
+ * - Mark *csp as immutable for grep_cgi_referrer().
+ *
+ * Revision 1.86 2007/01/09 11:54:26 fabiankeil
+ * Fix strdup() error handling in cgi_error_unknown()
+ * and cgi_error_no_template(). Reported by Markus Elfring.
+ *
+ * Revision 1.85 2007/01/05 14:19:02 fabiankeil
+ * Handle pcrs_execute() errors in template_fill() properly.
+ *
+ * Revision 1.84 2006/12/28 17:54:22 fabiankeil
+ * Fixed gcc43 conversion warnings and replaced sprintf
+ * calls with snprintf to give OpenBSD's gcc one less reason
+ * to complain.
+ *
+ * Revision 1.83 2006/12/17 19:35:19 fabiankeil
+ * Escape ampersand in Privoxy menu.
+ *
+ * Revision 1.82 2006/12/17 17:53:39 fabiankeil
+ * Suppress the toggle link if remote toggling is disabled.
+ *
+ * Revision 1.81 2006/12/09 13:49:16 fabiankeil
+ * Fix configure option --disable-toggle.
+ * Thanks to Peter Thoenen for reporting this.
+ *
+ * Revision 1.80 2006/12/08 14:45:32 fabiankeil
+ * Don't lose the FORCE_PREFIX in case of
+ * connection problems. Fixes #612235.
+ *
+ * Revision 1.79 2006/11/13 19:05:50 fabiankeil
+ * Make pthread mutex locking more generic. Instead of
+ * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
+ * and use mutex locking unless there is an _r function
+ * available. Better safe than sorry.
+ *
+ * Fixes "./configure --disable-pthread" and should result
+ * in less threading-related problems on pthread-using platforms,
+ * but it still doesn't fix BR#1122404.
+ *
+ * Revision 1.78 2006/09/21 19:22:07 fabiankeil
+ * Use CGI_PREFIX to check the referrer.
+ * The check for "http://config.privoxy.org/" fails
+ * if the user modified CGI_SITE_2_HOST.
+ *
+ * Revision 1.77 2006/09/21 15:17:23 fabiankeil
+ * Adjusted headers for Privoxy's cgi responses:
+ * Don't set Last-Modified, Expires and Cache-Control
+ * headers for redirects; always set "Connection: close".
+ *
+ * Revision 1.76 2006/09/07 14:06:38 fabiankeil
+ * Only predate the Last-Modified header for cgi responses
+ * that are delivered with status code 404 or 503.
+ *
+ * Revision 1.75 2006/09/07 11:56:39 fabiankeil
+ * Mark cgi_send_user_manual as harmless,
+ * to fix the access denied problem Hal spotted.
+ * The manual has no secret content, therefore we
+ * don't have to care about "secure" referrers.
+ *
+ * Revision 1.74 2006/09/06 18:45:03 fabiankeil
+ * Incorporate modified version of Roland Rosenfeld's patch to
+ * optionally access the user-manual via Privoxy. Closes patch 679075.
+ *
+ * Formatting changed to Privoxy style, added call to
+ * cgi_error_no_template if the requested file doesn't
+ * exist and modified check whether or not Privoxy itself
+ * should serve the manual. Should work cross-platform now.
+ *
+ * Revision 1.73 2006/08/03 02:46:41 david__schmidt
+ * Incorporate Fabian Keil's patch work:http://www.fabiankeil.de/sourcecode/privoxy/
+ *
+ * Revision 1.72 2006/07/18 14:48:45 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.70.2.13 2004/02/17 13:30:23 oes
+ * Moved cgi_error_disabled() from cgiedit.c to
+ * cgi.c to re-enable build with --disable-editor.
+ * Fixes Bug #892744. Thanks to Matthew Fischer
+ * for spotting.
+ *
+ * Revision 1.70.2.12 2003/12/17 16:33:16 oes
+ * - Added new function cgi_redirect to handle creation of
+ * HTTP redirect messages formerly repeated in the code.
+ * - Send cgi_error_disabled instead of cgi_error_404 when
+ * referrer check fails
+ * - Dynamic content now gets Expires header field with date
+ * in the past
+ *
+ * Revision 1.70.2.11 2003/10/23 12:29:26 oes
+ * Bugfix: Transparent PNG was not transparent. Thanks to
+ * Dan Razzell of Starfish Systems for notice and new PNG.
+ *
+ * Revision 1.70.2.10 2003/06/06 07:54:25 oes
+ * Security fix: dspatch_known_cgi no longer considers an empty
+ * referrer safe for critical CGIs, since malicious links could

+ *
+ * Revision 1.70.2.9 2003/05/08 15:11:31 oes
+ * Nit
+ *
+ * Revision 1.70.2.8 2003/04/29 13:33:51 oes
+ * Killed a compiler warning on OSX
+ *
+ * Revision 1.70.2.7 2003/04/03 13:50:58 oes
+ * - Don't call cgi_error_disabled ifndef FEATURE_CGI_EDIT_ACTIONS
+ * (fixes bug #710056)
+ * - Show toggle info only if we have it
+ *
+ * Revision 1.70.2.6 2003/03/12 01:26:25 david__schmidt
+ * Move declaration of struct tm dummy outside of a control block so it is
+ * accessible later on during snprintf in get_http_time.
+ *
+ * Revision 1.70.2.5 2003/03/11 11:53:58 oes
+ * Cosmetic: Renamed cryptic variable
+ *
+ * Revision 1.70.2.4 2003/03/07 03:41:03 david__schmidt
+ * Wrapping all *_r functions (the non-_r versions of them) with mutex semaphores for OSX. Hopefully this will take care of all of those pesky crash reports.
+ *
+ * Revision 1.70.2.3 2002/11/28 18:14:32 oes
+ * Disable access to critical CGIs via untrusted referrers.
+ * This prevents users from being tricked by malicious websites
+ * into making unintentional configuration changes:
+ *
+ * - Added flag to each cgi_dispatcher that allows or denies
+ * external linking
+ * - Introduced proviorical function that greps for the
+ * referrer header before regular header parsing happens
+ * - Added safety check to dispatch_known_cgi. CGI is called
+ * if (cgi harmless || no referrer || we are referrer).
+ * Else a) toggle calls are modified not to change status and
+ * b) all other calls are denied.
+ *
+ * Revision 1.70.2.2 2002/11/12 16:20:37 oes
+ * Added missing #ifdef FEATURE_TOGGLE around g_bToggleIJB; fixes bug #636651
+ *
+ * Revision 1.70.2.1 2002/08/05 11:17:46 oes
+ * Fixed Bug #587820, i.e. added workaround for IE bug that includes fragment identifier in (cgi) query
+ *
+ * Revision 1.70 2002/05/19 11:33:20 jongfoster
+ * If a CGI error was not handled, and propogated back to
+ * dispatch_known_cgi(), then it was assumed to be "out of memory".
+ * This gave a very misleading error message.
+ *
+ * Now other errors will cause a simple message giving the error
+ * number and asking the user to report a bug.
+ *
+ * Bug report:
+ * http://sourceforge.net/tracker/index.php?func=detail
+ * &aid=557905&group_id=11118&atid=111118

+ *
+ * Revision 1.61 2002/04/10 13:37:48 oes

+ * Revision 1.50 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the

+ * Automated function-comment nitpicking.
+ *
+ * Revision 1.44 2002/03/05 22:43:45 david__schmidt

+ *
+ * Revision 1.42 2002/01/21 00:33:20 jongfoster
+ * Replacing strsav() with the safer string_append() or string_join().
+ * Adding map_block_keep() to save a few bytes in the edit-actions-list HTML.
+ * Adding missing html_encode() to error message generators.
+ * Adding edit-actions-section-swap and many "shortcuts" to the list of CGIs.

+ * - Fixing || bug.
+ *
+ * Revision 1.37 2001/11/01 14:28:47 david__schmidt
+ * Show enablement/disablement status in almost all templates.
+ * There is a little trickiness here: apparent recursive resolution of
+ * @if-enabled-then@ caused the toggle template to show status out-of-phase with
+ * the actual enablement status. So a similar construct,
+ * @if-enabled-display-then@, is used to resolve the status display on non-'toggle'
+ * templates.
+ *
+ * Revision 1.36 2001/10/26 17:33:27 oes
+ * marginal bugfix
+ *
+ * Revision 1.35 2001/10/23 21:48:19 jongfoster
+ * Cleaning up error handling in CGI functions - they now send back
+ * a HTML error page and should never cause a FATAL error. (Fixes one
+ * potential source of "denial of service" attacks).
+ *
+ * CGI actions file editor that works and is actually useful.
+ *
+ * Ability to toggle Junkbuster remotely using a CGI call.
+ *
+ * You can turn off both the above features in the main configuration
+ * file, e.g. if you are running a multi-user proxy.
+ *
+ * Revision 1.34 2001/10/18 22:22:09 david__schmidt
+ * Only show "Local support" on templates conditionally:
+ * - if either 'admin-address' or 'proxy-info-url' are uncommented in config
+ * - if not, no Local support section appears
+ *
+ * Revision 1.33 2001/10/14 22:28:41 jongfoster
+ * Fixing stupid typo.
+ *
+ * Revision 1.32 2001/10/14 22:20:18 jongfoster
+ * - Changes to CGI dispatching method to match CGI names exactly,
+ * rather than doing a prefix match.
+ * - No longer need to count the length of the CGI handler names by hand.
+ * - Adding new handler for 404 error when disptching a CGI, if none of
+ * the handlers match.
+ * - Adding new handlers for CGI actionsfile editor.
+ *
+ * Revision 1.31 2001/10/10 10:56:39 oes
+ * Failiure to load template now fatal. Before, the user got a hard-to-understand assertion failure from cgi.c
+ *
+ * Revision 1.30 2001/10/02 15:30:57 oes
+ * Introduced show-request cgi
+ *
+ * Revision 1.29 2001/09/20 15:47:44 steudten
+ *
+ * Fix BUG: Modify int size to size_t size in fill_template()
+ * - removes big trouble on machines where sizeof(int) != sizeof(size_t).
+ *
+ * Revision 1.28 2001/09/19 18:00:37 oes
+ * - Deletef time() FIXME (Can't fail under Linux either, if
+ * the argument is guaranteed to be in out address space,
+ * which it is.)
+ * - Fixed comments
+ * - Pointer notation cosmetics
+ * - Fixed a minor bug in template_fill(): Failiure of
+ * pcrs_execute() now secure.
+ *
+ * Revision 1.27 2001/09/16 17:08:54 jongfoster
+ * Moving simple CGI functions from cgi.c to new file cgisimple.c
+ *
+ * Revision 1.26 2001/09/16 15:47:37 jongfoster
+ * First version of CGI-based edit interface. This is very much a
+ * work-in-progress, and you can't actually use it to edit anything
+ * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
+ * to have any effect.
+ *
+ * Revision 1.25 2001/09/16 15:02:35 jongfoster
+ * Adding i.j.b/robots.txt.
+ * Inlining add_stats() since it's only ever called from one place.
+ *
+ * Revision 1.24 2001/09/16 11:38:01 jongfoster
+ * Splitting fill_template() into 2 functions:
+ * template_load() loads the file
+ * template_fill() performs the PCRS regexps.
+ * This is because the CGI edit interface has a "table row"
+ * template which is used many times in the page - this
+ * change means it's only loaded from disk once.
+ *
+ * Revision 1.23 2001/09/16 11:16:05 jongfoster
+ * Better error handling in dispatch_cgi() and parse_cgi_parameters()
+ *
+ * Revision 1.22 2001/09/16 11:00:10 jongfoster
+ * New function alloc_http_response, for symmetry with free_http_response
+ *
+ * Revision 1.21 2001/09/13 23:53:03 jongfoster
+ * Support for both static and dynamically generated CGI pages.
+ * Correctly setting Last-Modified: and Expires: HTTP headers.
+ *
+ * Revision 1.20 2001/09/13 23:40:36 jongfoster
+ * (Cosmetic only) Indentation correction
+ *
+ * Revision 1.19 2001/09/13 23:31:25 jongfoster
+ * Moving image data to cgi.c rather than cgi.h.
+ *
+ * Revision 1.18 2001/08/05 16:06:20 jongfoster
+ * Modifiying "struct map" so that there are now separate header and
+ * "map_entry" structures. This means that functions which modify a
+ * map no longer need to return a pointer to the modified map.
+ * Also, it no longer reverses the order of the entries (which may be
+ * important with some advanced template substitutions).
+ *
+ * Revision 1.17 2001/08/05 15:57:38 oes
+ * Adapted finish_http_response to new list_to_text
+ *
+ * Revision 1.16 2001/08/01 21:33:18 jongfoster
+ * Changes to fill_template() that reduce memory usage without having
+ * an impact on performance. I also renamed some variables so as not
+ * to clash with the C++ keywords "new" and "template".
+ *
+ * Revision 1.15 2001/08/01 21:19:22 jongfoster
+ * Moving file version information to a separate CGI page.
+ *
+ * Revision 1.14 2001/08/01 00:19:03 jongfoster
+ * New function: map_conditional() for an if-then-else syntax.
+ * Changing to use new version of show_defines()
+ *
+ * Revision 1.13 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.12 2001/07/29 18:47:05 jongfoster
+ * Adding missing #include "loadcfg.h"
+ *
+ * Revision 1.11 2001/07/18 17:24:37 oes
+ * Changed to conform to new pcrs interface
+ *
+ * Revision 1.10 2001/07/13 13:53:13 oes
+ * Removed all #ifdef PCRS and related code
+ *
+ * Revision 1.9 2001/06/29 21:45:41 oes
+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.8 2001/06/29 13:21:46 oes
+ * - Cosmetics: renamed and reordered functions, variables,
+ * texts, improved comments etc
+ *
+ * - Removed ij_untrusted_url() The relevant
+ * info is now part of the "untrusted" page,
+ * which is generated by filters.c:trust_url()
+ *
+ * - Generators of content now call finish_http_response()
+ * themselves, making jcc.c:chat() a little less
+ * cluttered
+ *
+ * - Removed obsolete "Pragma: no-cache" from our headers
+ *
+ * - http_responses now know their head length
+ *
+ * - fill_template now uses the new interface to pcrs, so that
+ * - long jobs (like whole files) no longer have to be assembled
+ * in a fixed size buffer
+ * - the new T (trivial) option is used, and the replacement may
+ * contain Perl syntax backrefs without confusing pcrs
+ *
+ * - Introduced default_exports() which generates a set of exports
+ * common to all CGIs and other content generators
+ *
+ * - Introduced convenience function map_block_killer()
+ *
+ * - Introduced convenience function make_menu()
+ *
+ * - Introduced CGI-like function error_response() which generates
+ * the "No such domain" and "Connect failed" messages using the
+ * CGI platform
+ *
+ * - cgi_show_url_info:
+ * - adapted to new CGI features
+ * - form and answers now generated from same template
+ * - http:// prefix in URL now OK
+ *
+ * - cgi_show_status:
+ * - adapted to new CGI features
+ * - no longer uses csp->init_proxy_args
+ *
+ * - cgi_default:
+ * - moved menu generation to make_menu()
+ *
+ * - add_stats now writes single export map entries instead
+ * of a fixed string
+ *
+ * - Moved redirect_url() to filters.c
+ *
+ * - Fixed mem leak in free_http_response(), map_block_killer(),
+ *
+ * - Removed logentry from cancelled commit

+ * Revision 1.6 2001/06/07 23:05:19 jongfoster
+ * Removing code related to old forward and ACL files.
+ *
+ * Revision 1.5 2001/06/05 19:59:16 jongfoster
+ * Fixing multiline character string (a GCC-only "feature"), and snprintf (it's _snprintf under VC++).
+ *
+ * Revision 1.4 2001/06/04 10:41:52 swa
+ * show version string of cgi.h and cgi.c
+ *
+ * Revision 1.3 2001/06/03 19:12:16 oes

+ *
+ * Revision 1.29.2.2 2004/02/17 13:30:23 oes
+ * Moved cgi_error_disabled() from cgiedit.c to

+ * Revision 1.29 2002/05/19 11:33:21 jongfoster
+ * If a CGI error was not handled, and propogated back to
+ * dispatch_known_cgi(), then it was assumed to be "out of memory".
+ * This gave a very misleading error message.
+ *
+ * Now other errors will cause a simple message giving the error
+ * number and asking the user to report a bug.

+ * Revision 1.16 2001/09/16 17:08:54 jongfoster
+ * Moving simple CGI functions from cgi.c to new file cgisimple.c
+ *
+ * Revision 1.15 2001/09/16 15:02:35 jongfoster
+ * Adding i.j.b/robots.txt.
+ * Inlining add_stats() since it's only ever called from one place.
+ *
+ * Revision 1.14 2001/09/16 11:38:02 jongfoster
+ * Splitting fill_template() into 2 functions:
+ * template_load() loads the file
+ * template_fill() performs the PCRS regexps.
+ * This is because the CGI edit interface has a "table row"
+ * template which is used many times in the page - this
+ * change means it's only loaded from disk once.
+ *
+ * Revision 1.13 2001/09/16 11:00:10 jongfoster
+ * New function alloc_http_response, for symmetry with free_http_response
+ *
+ * Revision 1.12 2001/09/13 23:31:25 jongfoster
+ * Moving image data to cgi.c rather than cgi.h.
+ *
+ * Revision 1.11 2001/08/05 16:06:20 jongfoster
+ * Modifiying "struct map" so that there are now separate header and
+ * "map_entry" structures. This means that functions which modify a
+ * map no longer need to return a pointer to the modified map.
+ * Also, it no longer reverses the order of the entries (which may be
+ * important with some advanced template substitutions).
+ *
+ * Revision 1.10 2001/08/01 21:19:22 jongfoster
+ * Moving file version information to a separate CGI page.
+ *
+ * Revision 1.9 2001/08/01 00:17:54 jongfoster
+ * Adding prototype for map_conditional
+ *
+ * Revision 1.8 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.7 2001/07/29 18:43:08 jongfoster
+ * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
+ * ANSI C rules.
+ *
+ * Revision 1.6 2001/06/29 21:45:41 oes
+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.5 2001/06/29 13:22:44 oes
+ * - Cleaned up
+ * - Added new functions: default_exports(), make_menu(),
+ * error_response() etc, ranamed others and changed
+ * param and return types.
+ * - Removed HTTP/HTML snipplets
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.4 2001/06/09 10:50:58 jongfoster
+ * Changing "show URL info" handler to new style.
+ * Adding "extern" to some function prototypes.
+ *
+ * Revision 1.3 2001/06/03 19:12:16 oes
+ * introduced new cgi handling
+ *
+ * No revisions before 1.3

+ * Fixing gcc [CygWin] compiler warnings
+ *
+ * Revision 1.10 2002/01/23 00:22:59 jongfoster
+ * Adding new function cgi_edit_actions_section_swap(), to reorder
+ * the actions file.
+ *
+ * Adding get_url_spec_param() to get a validated URL pattern.
+ *
+ * Moving edit_read_line() out of this file and into loaders.c.
+ *
+ * Adding missing html_encode() to many CGI functions.
+ *
+ * Moving the functions that #include actionlist.h to the end of the file,
+ * because the Visual C++ 97 debugger gets extremely confused if you try
+ * to debug any code that comes after them in the file.
+ *
+ * Major optimizations in cgi_edit_actions_list() to reduce the size of
+ * the generated HTML (down 40% from 550k to 304k), with major side-effects
+ * throughout the editor and templates. In particular, the length of the
+ * URLs throughout the editor has been drastically reduced, by cutting
+ * paramater names down to 1 character and CGI names down to 3-4
+ * characters, by removing all non-essential CGI paramaters even at the
+ * expense of having to re-read the actions file for the most trivial
+ * page, and by using relative rather than absolute URLs. This means
+ * that this (typical example):
+ *
+ * <a href="http://ijbswa.sourceforge.net/config/edit-actions-url-form?
+ * filename=ijb&ver=1011487572&section=12&pattern=13
+ * &oldval=www.oesterhelt.org%2Fdeanimate-demo">
+ *
+ * is now this:
+ *
+ * <a href="eau?f=ijb&v=1011487572&p=13">
+ *
+ * Revision 1.9 2002/01/17 20:56:22 jongfoster
+ * Replacing hard references to the URL of the config interface
+ * with #defines from project.h
+ *
+ * Revision 1.8 2001/11/30 23:35:51 jongfoster
+ * Renaming actionsfile to ijb.action
+ *
+ * Revision 1.7 2001/11/13 00:28:24 jongfoster
+ * - Renaming parameters from edit-actions-for-url so that they only
+ * contain legal JavaScript characters. If we wanted to write
+ * JavaScript that worked with Netscape 4, this is nessacery.
+ * (Note that at the moment the JavaScript doesn't actually work
+ * with Netscape 4, but now this is purely a template issue, not
+ * one affecting code).
+ * - Adding new CGIs for use by non-JavaScript browsers:
+ * edit-actions-url-form
+ * edit-actions-add-url-form
+ * edit-actions-remove-url-form
+ * - Fixing || bug.
+ *
+ * Revision 1.6 2001/10/29 03:48:09 david__schmidt
+ * OS/2 native needed a snprintf() routine. Added one to miscutil, brackedted
+ * by and __OS2__ ifdef.
+ *
+ * Revision 1.5 2001/10/25 03:40:48 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.4 2001/10/23 21:48:19 jongfoster
+ * Cleaning up error handling in CGI functions - they now send back
+ * a HTML error page and should never cause a FATAL error. (Fixes one
+ * potential source of "denial of service" attacks).
+ *
+ * CGI actions file editor that works and is actually useful.
+ *
+ * Ability to toggle JunkBuster remotely using a CGI call.
+ *
+ * You can turn off both the above features in the main configuration
+ * file, e.g. if you are running a multi-user proxy.
+ *
+ * Revision 1.3 2001/10/14 22:12:49 jongfoster
+ * New version of CGI-based actionsfile editor.
+ * Major changes, including:
+ * - Completely new file parser and file output routines
+ * - edit-actions CGI renamed edit-actions-for-url
+ * - All CGIs now need a filename parameter, except for...
+ * - New CGI edit-actions which doesn't need a filename,
+ * to allow you to start the editor up.
+ * - edit-actions-submit now works, and now automatically
+ * redirects you back to the main edit-actions-list handler.
+ *
+ * Revision 1.2 2001/09/16 17:05:14 jongfoster
+ * Removing unused #include showarg.h
+ *
+ * Revision 1.1 2001/09/16 15:47:37 jongfoster
+ * First version of CGI-based edit interface. This is very much a
+ * work-in-progress, and you can't actually use it to edit anything
+ * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
+ * to have any effect.

+ * There's no reason to let remote toggling support depend
+ * on FEATURE_CGI_EDIT_ACTIONS, so make sure it doesn't.
+ *
+ * Revision 1.9 2006/07/18 14:48:45 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.7.2.2 2004/02/17 13:30:23 oes
+ * Moved cgi_error_disabled() from cgiedit.c to
+ * cgi.c to re-enable build with --disable-editor.
+ * Fixes Bug #892744. Thanks to Matthew Fischer
+ * for spotting.
+ *
+ * Revision 1.7.2.1 2002/11/28 18:15:17 oes
+ * Added cgi_error_disabled
+ *
+ * Revision 1.7 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * Revision 1.6 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.5 2002/01/22 23:24:48 jongfoster
+ * Adding edit-actions-section-swap
+ *
+ * Revision 1.4 2001/11/13 00:28:51 jongfoster
+ * Adding new CGIs for use by non-JavaScript browsers:
+ * edit-actions-url-form
+ * edit-actions-add-url-form
+ * edit-actions-remove-url-form
+ *
+ * Revision 1.3 2001/10/23 21:48:19 jongfoster
+ * Cleaning up error handling in CGI functions - they now send back
+ * a HTML error page and should never cause a FATAL error. (Fixes one
+ * potential source of "denial of service" attacks).
+ *
+ * CGI actions file editor that works and is actually useful.
+ *
+ * Ability to toggle JunkBuster remotely using a CGI call.
+ *
+ * You can turn off both the above features in the main configuration
+ * file, e.g. if you are running a multi-user proxy.
+ *
+ * Revision 1.2 2001/10/14 22:12:49 jongfoster
+ * New version of CGI-based actionsfile editor.
+ * Major changes, including:
+ * - Completely new file parser and file output routines
+ * - edit-actions CGI renamed edit-actions-for-url
+ * - All CGIs now need a filename parameter, except for...
+ * - New CGI edit-actions which doesn't need a filename,
+ * to allow you to start the editor up.
+ * - edit-actions-submit now works, and now automatically
+ * redirects you back to the main edit-actions-list handler.
+ *
+ * Revision 1.1 2001/09/16 15:47:37 jongfoster
+ * First version of CGI-based edit interface. This is very much a
+ * work-in-progress, and you can't actually use it to edit anything
+ * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
+ * to have any effect.

+ * - Use strlcpy() instead of strcpy().

+ *
+ * Revision 1.44 2006/12/22 14:19:27 fabiankeil
+ * Removed checks whether or not AF_FILES have
+ * data structures associated with them in cgi_show_status.
+ * It doesn't matter as we're only interested in the file names.
+ *
+ * For the action files the checks were always true,
+ * but they prevented empty filter files from being
+ * listed. Fixes parts of BR 1619208.
+ *
+ * Revision 1.43 2006/12/17 17:57:56 fabiankeil
+ * - Added FEATURE_GRACEFUL_TERMINATION to the

+ * Revision 1.41 2006/10/09 19:18:28 roro
+ * Redirect http://p.p/user-manual (without trailing slash) to
+ * http://p.p/user-manual/ (with trailing slash), otherwise links will be broken.
+ *
+ * Revision 1.40 2006/09/09 13:05:33 fabiankeil
+ * Modified cgi_send_user_manual to serve binary
+ * content without destroying it first. Should also be
+ * faster now. Added ".jpg" check for Content-Type guessing.
+ *
+ * Revision 1.39 2006/09/08 09:49:23 fabiankeil
+ * Deliver documents in the user-manual directory
+ * with "Content-Type text/css" if their filename
+ * ends with ".css".
+ *
+ * Revision 1.38 2006/09/06 18:45:03 fabiankeil
+ * Incorporate modified version of Roland Rosenfeld's patch to
+ * optionally access the user-manual via Privoxy. Closes patch 679075.
+ *
+ * Formatting changed to Privoxy style, added call to
+ * cgi_error_no_template if the requested file doesn't
+ * exist and modified check whether or not Privoxy itself
+ * should serve the manual. Should work cross-platform now.
+ *
+ * Revision 1.37 2006/07/18 14:48:45 david__schmidt

+ *
+ * Formatting changed to Privoxy style, added call to
+ * cgi_error_no_template if the requested file doesn't
+ * exist and modified check whether or not Privoxy itself
+ * should serve the manual. Should work cross-platform now.
+ *
+ * Revision 1.13 2006/07/18 14:48:45 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)

+####################################################################
+#
+#
+# I. INTRODUCTION
+# ===============
+#
+# This file holds Privoxy's main configuration. Privoxy detects
+# configuration changes automatically, so you don't have to restart
+# it unless you want to load a different configuration file.
+#
+# The configuration will be reloaded with the first request after
+# the change was done, this request itself will still use the old
+# configuration, though. In other words: it takes two requests before
+# you see the result of your changes. Requests that are dropped due
+# to ACL don't trigger reloads.
+#
+# When starting Privoxy on Unix systems, give the location of this
+# file as last argument. On Windows systems, Privoxy will look for
+# this file with the name 'config.txt' in the current working directory
+# of the Privoxy process.
+#
+#
+# II. FORMAT OF THE CONFIGURATION FILE
+# ====================================
+#
+# Configuration lines consist of an initial keyword followed by a
+# list of values, all separated by whitespace (any number of spaces
+# or tabs). For example,
+#
+# actionsfile default.action
+#
+# Indicates that the actionsfile is named 'default.action'.
+#
+# The '#' indicates a comment. Any part of a line following a '#'
+# is ignored, except if the '#' is preceded by a '\'.
+#
+# Thus, by placing a # at the start of an existing configuration
+# line, you can make it a comment and it will be treated as if it
+# weren't there. This is called "commenting out" an option and can
+# be useful. Removing the # again is called "uncommenting".
+#
+# Note that commenting out an option and leaving it at its default
+# are two completely different things! Most options behave very
+# differently when unset. See the "Effect if unset" explanation in
+# each option's description for details.
+#
+# Long lines can be continued on the next line by using a `\' as the
+# last character.
+#
+#
+#
+# 1. LOCAL SET-UP DOCUMENTATION
+# ==============================
+#
+# If you intend to operate Privoxy for more users than just yourself,
+# it might be a good idea to let them know how to reach you, what
+# you block and why you do that, your policies, etc.
+#
+#
+#
+# 1.1. user-manual
+# =================
+#
+# Specifies:
+#
+# Location of the Privoxy User Manual.
+#
+# Type of value:
+#
+# A fully qualified URI
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# http://www.privoxy.org/version/user-manual/ will be used,
+# where version is the Privoxy version.
+#
+# Notes:
+#
+# The User Manual URI is the single best source of information on
+# Privoxy, and is used for help links from some of the internal
+# CGI pages. The manual itself is normally packaged with the
+# binary distributions, so you probably want to set this to a
+# locally installed copy.
+#
+# Examples:
+#
+# The best all purpose solution is simply to put the full local
+# PATH to where the User Manual is located:
+#
+# user-manual /usr/share/doc/privoxy/user-manual
+#
+#
+# The User Manual is then available to anyone with
+# access to Privoxy, by following the built-in URL:
+# http://config.privoxy.org/user-manual/ (or the shortcut:
+# http://p.p/user-manual/)
+#
+# If the documentation is not on the local system, it can be
+# accessed from a remote server, as:
+#
+# user-manual http://example.com/privoxy/user-manual/
+#
+#
+# WARNING!!!
+#
+# If set, this option should be the first option in the config
+# file, because it is used while the config file is being read.
+#
+#user-manual http://www.privoxy.org/user-manual/
+#
+#
+# 1.2. trust-info-url
+# ====================
+#
+# Specifies:
+#
+# A URL to be displayed in the error page that users will see if
+# access to an untrusted page is denied.
+#
+# Type of value:
+#
+# URL
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# No links are displayed on the "untrusted" error page.
+#
+# Notes:
+#
+# The value of this option only matters if the experimental trust
+# mechanism has been activated. (See trustfile below.)
+#
+# If you use the trust mechanism, it is a good idea to write
+# up some on-line documentation about your trust policy and to
+# specify the URL(s) here. Use multiple times for multiple URLs.
+#
+# The URL(s) should be added to the trustfile as well, so users
+# don't end up locked out from the information on why they were
+# locked out in the first place!
+#
+#trust-info-url http://www.example.com/why_we_block.html
+#trust-info-url http://www.example.com/what_we_allow.html
+#
+#
+# 1.3. admin-address
+# ===================
+#
+# Specifies:
+#
+# An email address to reach the Privoxy administrator.
+#
+# Type of value:
+#
+# Email address
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# No email address is displayed on error pages and the CGI user
+# interface.
+#
+# Notes:
+#
+# If both admin-address and proxy-info-url are unset, the whole
+# "Local Privoxy Support" box on all generated pages will not
+# be shown.
+#
+#admin-address privoxy-admin(a)example.com
+#
+#
+# 1.4. proxy-info-url
+# ====================
+#
+# Specifies:
+#
+# A URL to documentation about the local Privoxy setup,
+# configuration or policies.
+#
+# Type of value:
+#
+# URL
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# No link to local documentation is displayed on error pages and
+# the CGI user interface.
+#
+# Notes:
+#
+# If both admin-address and proxy-info-url are unset, the whole
+# "Local Privoxy Support" box on all generated pages will not
+# be shown.
+#
+# This URL shouldn't be blocked ;-)
+#
+#proxy-info-url http://www.example.com/proxy-service.html
+#
+#
+# 2. CONFIGURATION AND LOG FILE LOCATIONS
+# ========================================
+#
+# Privoxy can (and normally does) use a number of other files for
+# additional configuration, help and logging. This section of the
+# configuration file tells Privoxy where to find those other files.
+#
+# The user running Privoxy, must have read permission for all
+# configuration files, and write permission to any files that would
+# be modified, such as log files and actions files.
+#
+#
+#
+# 2.1. confdir
+# =============
+#
+# Specifies:
+#
+# The directory where the other configuration files are located.
+#
+# Type of value:
+#
+# Path name
+#
+# Default value:
+#
+# /etc/privoxy (Unix) or Privoxy installation dir (Windows)
+#
+# Effect if unset:
+#
+# Mandatory
+#
+# Notes:
+#
+# No trailing "/", please.
+#
+confdir .
+#
+#
+# 2.2. templdir
+# ==============
+#
+# Specifies:
+#
+# An alternative directory where the templates are loaded from.
+#
+# Type of value:
+#
+# Path name
+#
+# Default value:
+#
+# unset
+#
+# Effect if unset:
+#
+# The templates are assumed to be located in confdir/template.
+#
+# Notes:
+#
+# Privoxy's original templates are usually overwritten with each
+# update. Use this option to relocate customized templates that
+# should be kept. As template variables might change between
+# updates, you shouldn't expect templates to work with Privoxy
+# releases other than the one they were part of, though.
+#
+#templdir .
+#
+#
+# 2.3. logdir
+# ============
+#
+# Specifies:
+#
+# The directory where all logging takes place (i.e. where the
+# logfile is located).
+#
+# Type of value:
+#
+# Path name
+#
+# Default value:
+#
+# /var/log/privoxy (Unix) or Privoxy installation dir (Windows)
+#
+# Effect if unset:
+#
+# Mandatory
+#
+# Notes:
+#
+# No trailing "/", please.
+#
+logdir .
+#
+#
+# 2.4. actionsfile
+# =================
+#
+# Specifies:
+#
+# The actions file(s) to use
+#
+# Type of value:
+#
+# Complete file name, relative to confdir
+#
+# Default values:
+#
+# match-all.action # Actions that are applied to all sites and maybe overruled later on.
+#
+# default.action # Main actions file
+#
+# user.action # User customizations
+#
+# Effect if unset:
+#
+# No actions are taken at all. More or less neutral proxying.
+#
+# Notes:
+#
+# Multiple actionsfile lines are permitted, and are in fact
+# recommended!
+#
+# The default values are default.action, which is the "main"
+# actions file maintained by the developers, and user.action,
+# where you can make your personal additions.
+#
+# Actions files contain all the per site and per URL configuration
+# for ad blocking, cookie management, privacy considerations,
+# etc. There is no point in using Privoxy without at least one
+# actions file.
+#
+# Note that since Privoxy 3.0.7, the complete filename, including
+# the ".action" extension has to be specified. The syntax change
+# was necessary to be consistent with the other file options and
+# to allow previously forbidden characters.
+#
+actionsfile match-all.action # Actions that are applied to all sites and maybe overruled later on.
+actionsfile default.action # Main actions file
+actionsfile user.action # User customizations
+#
+#
+# 2.5. filterfile
+# ================
+#
+# Specifies:
+#
+# The filter file(s) to use
+#
+# Type of value:
+#
+# File name, relative to confdir
+#
+# Default value:
+#
+# default.filter (Unix) or default.filter.txt (Windows)
+#
+# Effect if unset:
+#
+# No textual content filtering takes place, i.e. all +filter{name}
+# actions in the actions files are turned neutral.
+#
+# Notes:
+#
+# Multiple filterfile lines are permitted.
+#
+# The filter files contain content modification rules that use
+# regular expressions. These rules permit powerful changes on the
+# content of Web pages, and optionally the headers as well, e.g.,
+# you could try to disable your favorite JavaScript annoyances,
+# re-write the actual displayed text, or just have some fun
+# playing buzzword bingo with web pages.
+#
+# The +filter{name} actions rely on the relevant filter (name)
+# to be defined in a filter file!
+#
+# A pre-defined filter file called default.filter that contains a
+# number of useful filters for common problems is included in the
+# distribution. See the section on the filter action for a list.
+#
+# It is recommended to place any locally adapted filters into a
+# separate file, such as user.filter.
+#
+filterfile default.filter
+#filterfile user.filter # User customizations
+#
+#
+# 2.6. logfile
+# =============
+#
+# Specifies:
+#
+# The log file to use
+#
+# Type of value:
+#
+# File name, relative to logdir
+#
+# Default value:
+#
+# Unset (commented out). When activated: logfile (Unix) or
+# privoxy.log (Windows).
+#
+# Effect if unset:
+#
+# No logfile is written.
+#
+# Notes:
+#
+# The logfile is where all logging and error messages are
+# written. The level of detail and number of messages are set with
+# the debug option (see below). The logfile can be useful for
+# tracking down a problem with Privoxy (e.g., it's not blocking
+# an ad you think it should block) and it can help you to monitor
+# what your browser is doing.
+#
+# Depending on the debug options below, the logfile may be a
+# privacy risk if third parties can get access to it. As most
+# users will never look at it, Privoxy 3.0.7 and later only log
+# fatal errors by default.
+#
+# For most troubleshooting purposes, you will have to change that,
+# please refer to the debugging section for details.
+#
+# Your logfile will grow indefinitely, and you will probably
+# want to periodically remove it. On Unix systems, you can do
+# this with a cron job (see "man cron"). For Red Hat based Linux
+# distributions, a logrotate script has been included.
+#
+# Any log files must be writable by whatever user Privoxy is
+# being run as (on Unix, default user id is "privoxy").
+#
+logfile logfile
+#
+#
+# 2.7. trustfile
+# ===============
+#
+# Specifies:
+#
+# The name of the trust file to use
+#
+# Type of value:
+#
+# File name, relative to confdir
+#
+# Default value:
+#
+# Unset (commented out). When activated: trust (Unix) or trust.txt
+# (Windows)
+#
+# Effect if unset:
+#
+# The entire trust mechanism is disabled.
+#
+# Notes:
+#
+# The trust mechanism is an experimental feature for building
+# white-lists and should be used with care. It is NOT recommended
+# for the casual user.
+#
+# If you specify a trust file, Privoxy will only allow access to
+# sites that are specified in the trustfile. Sites can be listed
+# in one of two ways:
+#
+# Prepending a ~ character limits access to this site only (and
+# any sub-paths within this site), e.g. ~www.example.com allows
+# access to ~www.example.com/ features/news.html, etc.
+#
+# Or, you can designate sites as trusted referrers, by prepending
+# the name with a + character. The effect is that access to
+# untrusted sites will be granted -- but only if a link from
+# this trusted referrer was used to get there. The link target
+# will then be added to the "trustfile" so that future, direct
+# accesses will be granted. Sites added via this mechanism do
+# not become trusted referrers themselves (i.e. they are added
+# with a ~ designation). There is a limit of 512 such entries,
+# after which new entries will not be made.
+#
+# If you use the + operator in the trust file, it may grow
+# considerably over time.
+#
+# It is recommended that Privoxy be compiled with the
+# --disable-force, --disable-toggle and --disable-editor options,
+# if this feature is to be used.
+#
+# Possible applications include limiting Internet access for
+# children.
+#
+#trustfile trust
+#
+#
+# 3. DEBUGGING
+# =============
+#
+# These options are mainly useful when tracing a problem. Note that
+# you might also want to invoke Privoxy with the --no-daemon command
+# line option when debugging.
+#
+#
+#
+# 3.1. debug
+# ===========
+#
+# Specifies:
+#
+# Key values that determine what information gets logged.
+#
+# Type of value:
+#
+# Integer values
+#
+# Default value:
+#
+# 0 (i.e.: only fatal errors (that cause Privoxy to exit) are logged)
+#
+# Effect if unset:
+#
+# Default value is used (see above).
+#
+# Notes:
+#
+# The available debug levels are:
+#
+# debug 1 # Log the destination for each request Privoxy let through. See also debug 1024.
+# debug 2 # show each connection status
+# debug 4 # show I/O status
+# debug 8 # show header parsing
+# debug 16 # log all data written to the network into the logfile
+# debug 32 # debug force feature
+# debug 64 # debug regular expression filters
+# debug 128 # debug redirects
+# debug 256 # debug GIF de-animation
+# debug 512 # Common Log Format
+# debug 1024 # Log the destination for requests Privoxy didn't let through, and the reason why.
+# debug 2048 # CGI user interface
+# debug 4096 # Startup banner and warnings.
+# debug 8192 # Non-fatal errors
+#
+#
+# To select multiple debug levels, you can either add them or
+# use multiple debug lines.
+#
+# A debug level of 1 is informative because it will show you each
+# request as it happens. 1, 4096 and 8192 are recommended so that
+# you will notice when things go wrong. The other levels are
+# probably only of interest if you are hunting down a specific
+# problem. They can produce a hell of an output (especially 16).
+#
+# Privoxy used to ship with the debug levels recommended above
+# enabled by default, but due to privacy concerns 3.0.7 and later
+# are configured to only log fatal errors.
+#
+# If you are used to the more verbose settings, simply enable
+# the debug lines below again.
+#
+# If you want to use pure CLF (Common Log Format), you should set
+# "debug 512" ONLY and not enable anything else.
+#
+# Privoxy has a hard-coded limit for the length of log messages. If
+# it's reached, messages are logged truncated and marked with
+# "... [too long, truncated]".
+#
+# Please don't file any support requests without trying to
+# reproduce the problem with increased debug level first. Once
+# you read the log messages, you may even be able to solve the
+# problem on your own.
+#
+#debug 1 # Log the destination for each request Privoxy let through.
+#debug 1024 # Log the destination for requests Privoxy didn't let through, and the reason why.
+#debug 4096 # Startup banner and warnings
+#debug 8192 # Non-fatal errors
+#
+#
+# 3.2. single-threaded
+# =====================
+#
+# Specifies:
+#
+# Whether to run only one server thread.
+#
+# Type of value:
+#
+# None
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# Multi-threaded (or, where unavailable: forked) operation,
+# i.e. the ability to serve multiple requests simultaneously.
+#
+# Notes:
+#
+# This option is only there for debugging purposes. It will
+# drastically reduce performance.
+#
+#single-threaded
+#
+#
+# 3.3. hostname
+# ==============
+#
+# Specifies:
+#
+# The hostname shown on the CGI pages.
+#
+# Type of value:
+#
+# Text
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# The hostname provided by the operating system is used.
+#
+# Notes:
+#
+# On some misconfigured systems resolving the hostname fails or
+# takes too much time and slows Privoxy down. Setting a fixed
+# hostname works around the problem.
+#
+# In other circumstances it might be desirable to show a hostname
+# other than the one returned by the operating system. For example
+# if the system has several different hostnames and you don't
+# want to use the first one.
+#
+# Note that Privoxy does not validate the specified hostname value.
+#
+#hostname hostname.example.org
+#
+#
+# 4. ACCESS CONTROL AND SECURITY
+# ===============================
+#
+# This section of the config file controls the security-relevant
+# aspects of Privoxy's configuration.
+#
+#
+#
+# 4.1. listen-address
+# ====================
+#
+# Specifies:
+#
+# The IP address and TCP port on which Privoxy will listen for
+# client requests.
+#
+# Type of value:
+#
+# [IP-Address]:Port
+#
+# Default value:
+#
+# 127.0.0.1:8118
+#
+# Effect if unset:
+#
+# Bind to 127.0.0.1 (localhost), port 8118. This is suitable and
+# recommended for home users who run Privoxy on the same machine
+# as their browser.
+#
+# Notes:
+#
+# You will need to configure your browser(s) to this proxy address
+# and port.
+#
+# If you already have another service running on port 8118, or
+# if you want to serve requests from other machines (e.g. on your
+# local network) as well, you will need to override the default.
+#
+# If you leave out the IP address, Privoxy will bind to all
+# interfaces (addresses) on your machine and may become reachable
+# from the Internet. In that case, consider using access control
+# lists (ACL's, see below), and/or a firewall.
+#
+# If you open Privoxy to untrusted users, you will also
+# want to make sure that the following actions are disabled:
+# enable-edit-actions and enable-remote-toggle
+#
+# Example:
+#
+# Suppose you are running Privoxy on a machine which has the
+# address 192.168.0.1 on your local private network (192.168.0.0)
+# and has another outside connection with a different address. You
+# want it to serve requests from inside only:
+#
+# listen-address 192.168.0.1:8118
+#
+#
+listen-address 127.0.0.1:8118
+#
+#
+# 4.2. toggle
+# ============
+#
+# Specifies:
+#
+# Initial state of "toggle" status
+#
+# Type of value:
+#
+# 1 or 0
+#
+# Default value:
+#
+# 1
+#
+# Effect if unset:
+#
+# Act as if toggled on
+#
+# Notes:
+#
+# If set to 0, Privoxy will start in "toggled off" mode,
+# i.e. mostly behave like a normal, content-neutral proxy
+# with both ad blocking and content filtering disabled. See
+# enable-remote-toggle below.
+#
+# The windows version will only display the toggle icon in the
+# system tray if this option is present.
+#
+toggle 1
+#
+#
+# 4.3. enable-remote-toggle
+# ==========================
+#
+# Specifies:
+#
+# Whether or not the web-based toggle feature may be used
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# The web-based toggle feature is disabled.
+#
+# Notes:
+#
+# When toggled off, Privoxy mostly acts like a normal,
+# content-neutral proxy, i.e. doesn't block ads or filter content.
+#
+# Access to the toggle feature can not be controlled separately by
+# "ACLs" or HTTP authentication, so that everybody who can access
+# Privoxy (see "ACLs" and listen-address above) can toggle it
+# for all users. So this option is not recommended for multi-user
+# environments with untrusted users.
+#
+# Note that malicious client side code (e.g Java) is also capable
+# of using this option.
+#
+# As a lot of Privoxy users don't read documentation, this feature
+# is disabled by default.
+#
+# Note that you must have compiled Privoxy with support for this
+# feature, otherwise this option has no effect.
+#
+enable-remote-toggle 0
+#
+#
+# 4.4. enable-remote-http-toggle
+# ===============================
+#
+# Specifies:
+#
+# Whether or not Privoxy recognizes special HTTP headers to change
+# its behaviour.
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Privoxy ignores special HTTP headers.
+#
+# Notes:
+#
+# When toggled on, the client can change Privoxy's behaviour by
+# setting special HTTP headers. Currently the only supported
+# special header is "X-Filter: No", to disable filtering for
+# the ongoing request, even if it is enabled in one of the
+# action files.
+#
+# This feature is disabled by default. If you are using Privoxy in
+# a environment with trusted clients, you may enable this feature
+# at your discretion. Note that malicious client side code (e.g
+# Java) is also capable of using this feature.
+#
+# This option will be removed in future releases as it has been
+# obsoleted by the more general header taggers.
+#
+enable-remote-http-toggle 0
+#
+#
+# 4.5. enable-edit-actions
+# =========================
+#
+# Specifies:
+#
+# Whether or not the web-based actions file editor may be used
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# The web-based actions file editor is disabled.
+#
+# Notes:
+#
+# Access to the editor can not be controlled separately by
+# "ACLs" or HTTP authentication, so that everybody who can access
+# Privoxy (see "ACLs" and listen-address above) can modify its
+# configuration for all users.
+#
+# This option is not recommended for environments with untrusted
+# users and as a lot of Privoxy users don't read documentation,
+# this feature is disabled by default.
+#
+# Note that malicious client side code (e.g Java) is also capable
+# of using the actions editor and you shouldn't enable this
+# options unless you understand the consequences and are sure
+# your browser is configured correctly.
+#
+# Note that you must have compiled Privoxy with support for this
+# feature, otherwise this option has no effect.
+#
+enable-edit-actions 0
+#
+#
+# 4.6. enforce-blocks
+# ====================
+#
+# Specifies:
+#
+# Whether the user is allowed to ignore blocks and can "go there
+# anyway".
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Blocks are not enforced.
+#
+# Notes:
+#
+# Privoxy is mainly used to block and filter requests as a service
+# to the user, for example to block ads and other junk that clogs
+# the pipes. Privoxy's configuration isn't perfect and sometimes
+# innocent pages are blocked. In this situation it makes sense to
+# allow the user to enforce the request and have Privoxy ignore
+# the block.
+#
+# In the default configuration Privoxy's "Blocked" page contains
+# a "go there anyway" link to adds a special string (the force
+# prefix) to the request URL. If that link is used, Privoxy
+# will detect the force prefix, remove it again and let the
+# request pass.
+#
+# Of course Privoxy can also be used to enforce a network
+# policy. In that case the user obviously should not be able to
+# bypass any blocks, and that's what the "enforce-blocks" option
+# is for. If it's enabled, Privoxy hides the "go there anyway"
+# link. If the user adds the force prefix by hand, it will not
+# be accepted and the circumvention attempt is logged.
+#
+# Examples:
+#
+# enforce-blocks 1
+#
+enforce-blocks 0
+#
+#
+# 4.7. ACLs: permit-access and deny-access
+# =========================================
+#
+# Specifies:
+#
+# Who can access what.
+#
+# Type of value:
+#
+# src_addr[/src_masklen] [dst_addr[/dst_masklen]]
+#
+# Where src_addr and dst_addr are IP addresses in dotted decimal
+# notation or valid DNS names, and src_masklen and dst_masklen are
+# subnet masks in CIDR notation, i.e. integer values from 2 to 30
+# representing the length (in bits) of the network address. The
+# masks and the whole destination part are optional.
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# Don't restrict access further than implied by listen-address
+#
+# Notes:
+#
+# Access controls are included at the request of ISPs and systems
+# administrators, and are not usually needed by individual
+# users. For a typical home user, it will normally suffice to
+# ensure that Privoxy only listens on the localhost (127.0.0.1)
+# or internal (home) network address by means of the listen-address
+# option.
+#
+# Please see the warnings in the FAQ that Privoxy is not intended
+# to be a substitute for a firewall or to encourage anyone to
+# defer addressing basic security weaknesses.
+#
+# Multiple ACL lines are OK. If any ACLs are specified, Privoxy
+# only talks to IP addresses that match at least one permit-access
+# line and don't match any subsequent deny-access line. In other
+# words, the last match wins, with the default being deny-access.
+#
+# If Privoxy is using a forwarder (see forward below) for a
+# particular destination URL, the dst_addr that is examined is
+# the address of the forwarder and NOT the address of the ultimate
+# target. This is necessary because it may be impossible for the
+# local Privoxy to determine the IP address of the ultimate target
+# (that's often what gateways are used for).
+#
+# You should prefer using IP addresses over DNS names, because
+# the address lookups take time. All DNS names must resolve! You
+# can not use domain patterns like "*.org" or partial domain
+# names. If a DNS name resolves to multiple IP addresses, only
+# the first one is used.
+#
+# Denying access to particular sites by ACL may have undesired
+# side effects if the site in question is hosted on a machine
+# which also hosts other sites (most sites are).
+#
+# Examples:
+#
+# Explicitly define the default behavior if no ACL and
+# listen-address are set: "localhost" is OK. The absence of a
+# dst_addr implies that all destination addresses are OK:
+#
+# permit-access localhost
+#
+#
+# Allow any host on the same class C subnet as www.privoxy.org
+# access to nothing but www.example.com (or other domains hosted
+# on the same system):
+#
+# permit-access www.privoxy.org/24 www.example.com/32
+#
+#
+# Allow access from any host on the 26-bit subnet 192.168.45.64 to
+# anywhere, with the exception that 192.168.45.73 may not access
+# the IP address behind www.dirty-stuff.example.com:
+#
+# permit-access 192.168.45.64/26
+# deny-access 192.168.45.73 www.dirty-stuff.example.com
+#
+#
+#
+# 4.8. buffer-limit
+# ==================
+#
+# Specifies:
+#
+# Maximum size of the buffer for content filtering.
+#
+# Type of value:
+#
+# Size in Kbytes
+#
+# Default value:
+#
+# 4096
+#
+# Effect if unset:
+#
+# Use a 4MB (4096 KB) limit.
+#
+# Notes:
+#
+# For content filtering, i.e. the +filter and +deanimate-gif
+# actions, it is necessary that Privoxy buffers the entire document
+# body. This can be potentially dangerous, since a server could
+# just keep sending data indefinitely and wait for your RAM to
+# exhaust -- with nasty consequences. Hence this option.
+#
+# When a document buffer size reaches the buffer-limit, it is
+# flushed to the client unfiltered and no further attempt to filter
+# the rest of the document is made. Remember that there may be
+# multiple threads running, which might require up to buffer-limit
+# Kbytes each, unless you have enabled "single-threaded" above.
+#
+buffer-limit 4096
+#
+#
+# 5. FORWARDING
+# ==============
+#
+# This feature allows routing of HTTP requests through a chain of
+# multiple proxies.
+#
+# Forwarding can be used to chain Privoxy with a caching proxy to
+# speed up browsing. Using a parent proxy may also be necessary if
+# the machine that Privoxy runs on has no direct Internet access.
+#
+# Note that parent proxies can severely decrease your privacy
+# level. For example a parent proxy could add your IP address to the
+# request headers and if it's a caching proxy it may add the "Etag"
+# header to revalidation requests again, even though you configured
+# Privoxy to remove it. It may also ignore Privoxy's header time
+# randomization and use the original values which could be used by
+# the server as cookie replacement to track your steps between visits.
+#
+# Also specified here are SOCKS proxies. Privoxy supports the SOCKS
+# 4 and SOCKS 4A protocols.
+#
+#
+#
+# 5.1. forward
+# =============
+#
+# Specifies:
+#
+# To which parent HTTP proxy specific requests should be routed.
+#
+# Type of value:
+#
+# target_pattern http_parent[:port]
+#
+# where target_pattern is a URL pattern that specifies to which
+# requests (i.e. URLs) this forward rule shall apply. Use /
+# to denote "all URLs". http_parent[:port] is the DNS name or
+# IP address of the parent HTTP proxy through which the requests
+# should be forwarded, optionally followed by its listening port
+# (default: 8080). Use a single dot (.) to denote "no forwarding".
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# Don't use parent HTTP proxies.
+#
+# Notes:
+#
+# If http_parent is ".", then requests are not forwarded to
+# another HTTP proxy but are made directly to the web servers.
+#
+# Multiple lines are OK, they are checked in sequence, and the
+# last match wins.
+#
+# Examples:
+#
+# Everything goes to an example parent proxy, except SSL on port
+# 443 (which it doesn't handle):
+#
+# forward / parent-proxy.example.org:8080
+# forward :443 .
+#
+#
+# Everything goes to our example ISP's caching proxy, except for
+# requests to that ISP's sites:
+#
+# forward / caching-proxy.isp.example.net:8000
+# forward .isp.example.net .
+#
+#
+#
+#
+# 5.2. forward-socks4, forward-socks4a and forward-socks5
+# ========================================================
+#
+# Specifies:
+#
+# Through which SOCKS proxy (and optionally to which parent HTTP
+# proxy) specific requests should be routed.
+#
+# Type of value:
+#
+# target_pattern socks_proxy[:port] http_parent[:port]
+#
+# where target_pattern is a URL pattern that specifies to which
+# requests (i.e. URLs) this forward rule shall apply. Use / to
+# denote "all URLs". http_parent and socks_proxy are IP addresses
+# in dotted decimal notation or valid DNS names (http_parent may
+# be "." to denote "no HTTP forwarding"), and the optional port
+# parameters are TCP ports, i.e. integer values from 1 to 65535
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# Don't use SOCKS proxies.
+#
+# Notes:
+#
+# Multiple lines are OK, they are checked in sequence, and the
+# last match wins.
+#
+# The difference between forward-socks4 and forward-socks4a
+# is that in the SOCKS 4A protocol, the DNS resolution of the
+# target hostname happens on the SOCKS server, while in SOCKS 4
+# it happens locally.
+#
+# With forward-socks5 the DNS resolution will happen on the remote
+# server as well.
+#
+# If http_parent is ".", then requests are not forwarded to another
+# HTTP proxy but are made (HTTP-wise) directly to the web servers,
+# albeit through a SOCKS proxy.
+#
+# Examples:
+#
+# From the company example.com, direct connections are made to all
+# "internal" domains, but everything outbound goes through their
+# ISP's proxy by way of example.com's corporate SOCKS 4A gateway
+# to the Internet.
+#
+# forward-socks4a / socks-gw.example.com:1080 www-cache.isp.example.net:8080
+# forward .example.com .
+#
+#
+# A rule that uses a SOCKS 4 gateway for all destinations but no
+# HTTP parent looks like this:
+#
+# forward-socks4 / socks-gw.example.com:1080 .
+#
+#
+# To chain Privoxy and Tor, both running on the same system,
+# you would use something like:
+#
+# forward-socks4a / 127.0.0.1:9050 .
+#
+#
+# The public Tor network can't be used to reach your local network,
+# if you need to access local servers you therefore might want
+# to make some exceptions:
+#
+# forward 192.168.*.*/ .
+# forward 10.*.*.*/ .
+# forward 127.*.*.*/ .
+#
+#
+# Unencrypted connections to systems in these address ranges will
+# be as (un) secure as the local network is, but the alternative
+# is that you can't reach the local network through Privoxy at
+# all. Of course this may actually be desired and there is no
+# reason to make these exceptions if you aren't sure you need them.
+#
+# If you also want to be able to reach servers in your local
+# network by using their names, you will need additional exceptions
+# that look like this:
+#
+# forward localhost/ .
+#
+#
+#
+#
+# 5.3. forwarded-connect-retries
+# ===============================
+#
+# Specifies:
+#
+# How often Privoxy retries if a forwarded connection request
+# fails.
+#
+# Type of value:
+#
+# Number of retries.
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Connections forwarded through other proxies are treated like
+# direct connections and no retry attempts are made.
+#
+# Notes:
+#
+# forwarded-connect-retries is mainly interesting for socks4a
+# connections, where Privoxy can't detect why the connections
+# failed. The connection might have failed because of a DNS timeout
+# in which case a retry makes sense, but it might also have failed
+# because the server doesn't exist or isn't reachable. In this
+# case the retry will just delay the appearance of Privoxy's
+# error message.
+#
+# Note that in the context of this option, "forwarded connections"
+# includes all connections that Privoxy forwards through other
+# proxies. This option is not limited to the HTTP CONNECT method.
+#
+# Only use this option, if you are getting lots of
+# forwarding-related error messages that go away when you try again
+# manually. Start with a small value and check Privoxy's logfile
+# from time to time, to see how many retries are usually needed.
+#
+# Examples:
+#
+# forwarded-connect-retries 1
+#
+forwarded-connect-retries 0
+#
+#
+# 5.4. accept-intercepted-requests
+# =================================
+#
+# Specifies:
+#
+# Whether intercepted requests should be treated as valid.
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Only proxy requests are accepted, intercepted requests are
+# treated as invalid.
+#
+# Notes:
+#
+# If you don't trust your clients and want to force them to use
+# Privoxy, enable this option and configure your packet filter
+# to redirect outgoing HTTP connections into Privoxy.
+#
+# Make sure that Privoxy's own requests aren't redirected as well.
+# Additionally take care that Privoxy can't intentionally connect
+# to itself, otherwise you could run into redirection loops if
+# Privoxy's listening port is reachable by the outside or an
+# attacker has access to the pages you visit.
+#
+# Examples:
+#
+# accept-intercepted-requests 1
+#
+accept-intercepted-requests 0
+#
+#
+# 5.5. allow-cgi-request-crunching
+# =================================
+#
+# Specifies:
+#
+# Whether requests to Privoxy's CGI pages can be blocked or
+# redirected.
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Privoxy ignores block and redirect actions for its CGI pages.
+#
+# Notes:
+#
+# By default Privoxy ignores block or redirect actions for
+# its CGI pages. Intercepting these requests can be useful in
+# multi-user setups to implement fine-grained access control,
+# but it can also render the complete web interface useless and
+# make debugging problems painful if done without care.
+#
+# Don't enable this option unless you're sure that you really
+# need it.
+#
+# Examples:
+#
+# allow-cgi-request-crunching 1
+#
+allow-cgi-request-crunching 0
+#
+#
+# 5.6. split-large-forms
+# =======================
+#
+# Specifies:
+#
+# Whether the CGI interface should stay compatible with broken
+# HTTP clients.
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# The CGI form generate long GET URLs.
+#
+# Notes:
+#
+# Privoxy's CGI forms can lead to rather long URLs. This isn't
+# a problem as far as the HTTP standard is concerned, but it can
+# confuse clients with arbitrary URL length limitations.
+#
+# Enabling split-large-forms causes Privoxy to divide big forms
+# into smaller ones to keep the URL length down. It makes editing
+# a lot less convenient and you can no longer submit all changes
+# at once, but at least it works around this browser bug.
+#
+# If you don't notice any editing problems, there is no reason
+# to enable this option, but if one of the submit buttons appears
+# to be broken, you should give it a try.
+#
+# Examples:
+#
+# split-large-forms 1
+#
+split-large-forms 0
+#
+#
+# 5.7. keep-alive-timeout
+# ========================
+#
+# Specifies:
+#
+# Number of seconds after which an open connection will no longer
+# be reused.
+#
+# Type of value:
+#
+# Time in seconds.
+#
+# Default value:
+#
+# None
+#
+# Effect if unset:
+#
+# Connections are not reused.
+#
+# Notes:
+#
+# This option has no effect if Privoxy has been compiled without
+# keep-alive support.
+#
+# Notes:
+#
+# Note that reusing connections doesn't necessary cause
+# speedups. There are also a few privacy implications you should
+# be aware of.
+#
+# Outgoing connections are shared between clients (if there are
+# more than one) and closing the client that initiated the outgoing
+# connection does not affect the connection between Privoxy and
+# the server unless the client's request hasn't been completed
+# yet. If the outgoing connection is idle, it will not be closed
+# until either Privoxy's or the server's timeout is reached. While
+# it's open, the server knows that the system running Privoxy is
+# still there.
+#
+# Examples:
+#
+# keep-alive-timeout 300
+#
+keep-alive-timeout 300
+#
+#
+# 5.8. socket-timeout
+# ====================
+#
+# Specifies:
+#
+# Number of seconds after which a socket times out if no data
+# is received.
+#
+# Type of value:
+#
+# Time in seconds.
+#
+# Default value:
+#
+# None
+#
+# Effect if unset:
+#
+# A default value of 300 seconds is used.
+#
+# Notes:
+#
+# For SOCKS requests the timeout currently doesn't start until
+# the SOCKS server accepted the request. This will be fixed in
+# the next release.
+#
+# Examples:
+#
+# socket-timeout 300
+#
+socket-timeout 300
+#
+#
+# 6. WINDOWS GUI OPTIONS
+# =======================
+#
+# Privoxy has a number of options specific to the Windows GUI
+# interface:
+#
+#
+# If "activity-animation" is set to 1, the Privoxy icon will animate
+# when "Privoxy" is active. To turn off, set to 0.
+#
+#activity-animation 1
+#
+# If "log-messages" is set to 1, Privoxy will log messages to the
+# console window:
+#
+#log-messages 1
+#
+# If "log-buffer-size" is set to 1, the size of the log buffer,
+# i.e. the amount of memory used for the log messages displayed in
+# the console window, will be limited to "log-max-lines" (see below).
+#
+# Warning: Setting this to 0 will result in the buffer to grow
+# infinitely and eat up all your memory!
+#
+#log-buffer-size 1
+#
+# log-max-lines is the maximum number of lines held in the log
+# buffer. See above.
+#
+#log-max-lines 200
+#
+# If "log-highlight-messages" is set to 1, Privoxy will highlight
+# portions of the log messages with a bold-faced font:
+#
+#log-highlight-messages 1
+#
+# The font used in the console window:
+#
+#log-font-name Comic Sans MS
+#
+# Font size used in the console window:
+#
+#log-font-size 8
+#
+# "show-on-task-bar" controls whether or not Privoxy will appear as
+# a button on the Task bar when minimized:
+#
+#show-on-task-bar 0
+#
+# If "close-button-minimizes" is set to 1, the Windows close button
+# will minimize Privoxy instead of closing the program (close with
+# the exit option on the File menu).
+#
+#close-button-minimizes 1
+#
+# The "hide-console" option is specific to the MS-Win console version
+# of Privoxy. If this option is used, Privoxy will disconnect from
+# and hide the command console.
+#
+#hide-console

+ * and removed PCRE.
+ * (REGEX = REGEX_GNU || REGEX_PCRE per project.h)
+ * - Moved STATIC (for pcre) here from Makefile.in
+ * - Introduced STATIC_PCRS #define to allow for dynaimc linking with
+ * libpcrs
+ * - Removed PCRS #define, since pcrs is now needed for CGI anyway
+ *
+ * Revision 1.4 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.3 2001/05/26 01:26:34 jongfoster
+ * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.
+ * This #define cannot be set from ./configure - there's no point, it
+ * doesn't work yet. See feature request # 425722
+ *
+ * Revision 1.2 2001/05/22 17:43:35 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Many minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:45 oes

+ * Removed FEATURE_DENY_GZIP
+ *
+ * Revision 1.12 2001/09/13 19:56:37 jongfoster
+ * Reverting to revision 1.10 - previous checking was majorly broken.
+ *
+ * Revision 1.10 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.9 2001/07/29 19:08:52 jongfoster
+ * Changing _CONFIG_H to CONFIG_H_INCLUDED.
+ * Also added protection against using a MinGW32 or CygWin version of
+ * config.h from within MS Visual C++
+ *
+ * Revision 1.8 2001/07/29 17:09:17 jongfoster
+ * Major changes to build system in order to fix these bugs:
+ * - pthreads under Linux was broken - changed -lpthread to -pthread
+ * - Compiling in MinGW32 mode under CygWin now correctly detects
+ * which shared libraries are available
+ * - Solaris support (?) (Not tested under Solaris yet)
+ *
+ * Revision 1.7 2001/07/25 22:53:59 jongfoster
+ * Will #error if pthreads is enabled under BeOs
+ *
+ * Revision 1.6 2001/07/15 17:54:29 jongfoster
+ * Renaming #define STATIC to STATIC_PCRE
+ * Adding new #define FEATURE_PTHREAD that will be used to enable
+ * POSIX threads support.
+ *
+ * Revision 1.5 2001/07/13 13:48:37 oes
+ * - (Fix:) Copied CODE_STATUS #define from config.h.in
+ * - split REGEX #define into REGEX_GNU and REGEX_PCRE
+ * and removed PCRE.
+ * (REGEX = REGEX_GNU || REGEX_PCRE per project.h)
+ * - Moved STATIC (for pcre) here from Makefile.in
+ * - Introduced STATIC_PCRS #define to allow for dynaimc linking with
+ * libpcrs
+ * - Removed PCRS #define, since pcrs is now needed for CGI anyway
+ *
+ * Revision 1.4 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.3 2001/05/26 01:26:34 jongfoster
+ * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.
+ * This #define cannot be set from ./configure - there's no point, it
+ * doesn't work yet. See feature request # 425722
+ *
+ * Revision 1.2 2001/05/22 17:43:35 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Many minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:45 oes
+ * Initial import of version 2.9.3 source tree

+####################################################################
+#
+#
+# I. INTRODUCTION
+# ===============
+#
+# This file holds Privoxy's main configuration. Privoxy detects
+# configuration changes automatically, so you don't have to restart
+# it unless you want to load a different configuration file.
+#
+# The configuration will be reloaded with the first request after
+# the change was done, this request itself will still use the old
+# configuration, though. In other words: it takes two requests before
+# you see the result of your changes. Requests that are dropped due
+# to ACL don't trigger reloads.
+#
+# When starting Privoxy on Unix systems, give the location of this
+# file as last argument. On Windows systems, Privoxy will look for
+# this file with the name 'config.txt' in the current working directory
+# of the Privoxy process.
+#
+#
+# II. FORMAT OF THE CONFIGURATION FILE
+# ====================================
+#
+# Configuration lines consist of an initial keyword followed by a
+# list of values, all separated by whitespace (any number of spaces
+# or tabs). For example,
+#
+# actionsfile default.action
+#
+# Indicates that the actionsfile is named 'default.action'.
+#
+# The '#' indicates a comment. Any part of a line following a '#'
+# is ignored, except if the '#' is preceded by a '\'.
+#
+# Thus, by placing a # at the start of an existing configuration
+# line, you can make it a comment and it will be treated as if it
+# weren't there. This is called "commenting out" an option and can
+# be useful. Removing the # again is called "uncommenting".
+#
+# Note that commenting out an option and leaving it at its default
+# are two completely different things! Most options behave very
+# differently when unset. See the "Effect if unset" explanation in
+# each option's description for details.
+#
+# Long lines can be continued on the next line by using a `\' as the
+# last character.
+#
+#
+#
+# 1. LOCAL SET-UP DOCUMENTATION
+# ==============================
+#
+# If you intend to operate Privoxy for more users than just yourself,
+# it might be a good idea to let them know how to reach you, what
+# you block and why you do that, your policies, etc.
+#
+#
+#
+# 1.1. user-manual
+# =================
+#
+# Specifies:
+#
+# Location of the Privoxy User Manual.
+#
+# Type of value:
+#
+# A fully qualified URI
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# http://www.privoxy.org/version/user-manual/ will be used,
+# where version is the Privoxy version.
+#
+# Notes:
+#
+# The User Manual URI is the single best source of information on
+# Privoxy, and is used for help links from some of the internal
+# CGI pages. The manual itself is normally packaged with the
+# binary distributions, so you probably want to set this to a
+# locally installed copy.
+#
+# Examples:
+#
+# The best all purpose solution is simply to put the full local
+# PATH to where the User Manual is located:
+#
+# user-manual /usr/share/doc/privoxy/user-manual
+#
+#
+# The User Manual is then available to anyone with
+# access to Privoxy, by following the built-in URL:
+# http://config.privoxy.org/user-manual/ (or the shortcut:
+# http://p.p/user-manual/)
+#
+# If the documentation is not on the local system, it can be
+# accessed from a remote server, as:
+#
+# user-manual http://example.com/privoxy/user-manual/
+#
+#
+# WARNING!!!
+#
+# If set, this option should be the first option in the config
+# file, because it is used while the config file is being read.
+#
+user-manual /home/halb/privoxy/share/doc/privoxy/user-manual/
+#
+#
+# 1.2. trust-info-url
+# ====================
+#
+# Specifies:
+#
+# A URL to be displayed in the error page that users will see if
+# access to an untrusted page is denied.
+#
+# Type of value:
+#
+# URL
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# No links are displayed on the "untrusted" error page.
+#
+# Notes:
+#
+# The value of this option only matters if the experimental trust
+# mechanism has been activated. (See trustfile below.)
+#
+# If you use the trust mechanism, it is a good idea to write
+# up some on-line documentation about your trust policy and to
+# specify the URL(s) here. Use multiple times for multiple URLs.
+#
+# The URL(s) should be added to the trustfile as well, so users

+#
+#
+# 1.3. admin-address
+# ===================
+#
+# Specifies:
+#
+# An email address to reach the Privoxy administrator.
+#
+# Type of value:
+#
+# Email address
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# No email address is displayed on error pages and the CGI user
+# interface.
+#
+# Notes:
+#
+# If both admin-address and proxy-info-url are unset, the whole
+# "Local Privoxy Support" box on all generated pages will not
+# be shown.
+#
+#admin-address privoxy-admin(a)example.com
+#
+#
+# 1.4. proxy-info-url
+# ====================
+#
+# Specifies:
+#
+# A URL to documentation about the local Privoxy setup,
+# configuration or policies.
+#
+# Type of value:
+#
+# URL
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# No link to local documentation is displayed on error pages and
+# the CGI user interface.
+#
+# Notes:
+#
+# If both admin-address and proxy-info-url are unset, the whole

+#
+# This URL shouldn't be blocked ;-)
+#
+#proxy-info-url http://www.example.com/proxy-service.html
+#
+#
+# 2. CONFIGURATION AND LOG FILE LOCATIONS
+# ========================================
+#
+# Privoxy can (and normally does) use a number of other files for
+# additional configuration, help and logging. This section of the
+# configuration file tells Privoxy where to find those other files.
+#
+# The user running Privoxy, must have read permission for all
+# configuration files, and write permission to any files that would
+# be modified, such as log files and actions files.
+#
+#
+#
+# 2.1. confdir
+# =============
+#
+# Specifies:
+#
+# The directory where the other configuration files are located.
+#
+# Type of value:
+#
+# Path name
+#
+# Default value:
+#
+# /etc/privoxy (Unix) or Privoxy installation dir (Windows)
+#
+# Effect if unset:
+#
+# Mandatory
+#
+# Notes:
+#
+# No trailing "/", please.
+#
+confdir /home/halb/privoxy/etc
+#
+#
+# 2.2. templdir
+# ==============
+#
+# Specifies:
+#
+# An alternative directory where the templates are loaded from.
+#
+# Type of value:
+#
+# Path name
+#
+# Default value:
+#
+# unset
+#
+# Effect if unset:
+#
+# The templates are assumed to be located in confdir/template.
+#
+# Notes:
+#
+# Privoxy's original templates are usually overwritten with each
+# update. Use this option to relocate customized templates that
+# should be kept. As template variables might change between
+# updates, you shouldn't expect templates to work with Privoxy
+# releases other than the one they were part of, though.
+#
+#templdir .
+#
+#
+# 2.3. logdir
+# ============
+#
+# Specifies:
+#
+# The directory where all logging takes place (i.e. where the
+# logfile is located).
+#
+# Type of value:
+#
+# Path name
+#
+# Default value:
+#
+# /var/log/privoxy (Unix) or Privoxy installation dir (Windows)
+#
+# Effect if unset:
+#
+# Mandatory
+#
+# Notes:
+#
+# No trailing "/", please.
+#
+logdir /home/halb/privoxy/var/log/privoxy
+#
+#
+# 2.4. actionsfile
+# =================
+#
+# Specifies:
+#
+# The actions file(s) to use
+#
+# Type of value:
+#
+# Complete file name, relative to confdir
+#
+# Default values:
+#
+# match-all.action # Actions that are applied to all sites and maybe overruled later on.
+#
+# default.action # Main actions file
+#
+# user.action # User customizations
+#
+# Effect if unset:
+#
+# No actions are taken at all. More or less neutral proxying.
+#
+# Notes:
+#
+# Multiple actionsfile lines are permitted, and are in fact
+# recommended!
+#
+# The default values are default.action, which is the "main"
+# actions file maintained by the developers, and user.action,
+# where you can make your personal additions.
+#
+# Actions files contain all the per site and per URL configuration
+# for ad blocking, cookie management, privacy considerations,
+# etc. There is no point in using Privoxy without at least one
+# actions file.
+#
+# Note that since Privoxy 3.0.7, the complete filename, including
+# the ".action" extension has to be specified. The syntax change
+# was necessary to be consistent with the other file options and
+# to allow previously forbidden characters.
+#
+actionsfile match-all.action # Actions that are applied to all sites and maybe overruled later on.
+actionsfile default.action # Main actions file
+actionsfile user.action # User customizations
+#
+#
+# 2.5. filterfile
+# ================
+#
+# Specifies:
+#
+# The filter file(s) to use
+#
+# Type of value:
+#
+# File name, relative to confdir
+#
+# Default value:
+#
+# default.filter (Unix) or default.filter.txt (Windows)
+#
+# Effect if unset:
+#
+# No textual content filtering takes place, i.e. all +filter{name}
+# actions in the actions files are turned neutral.
+#
+# Notes:
+#
+# Multiple filterfile lines are permitted.
+#
+# The filter files contain content modification rules that use
+# regular expressions. These rules permit powerful changes on the
+# content of Web pages, and optionally the headers as well, e.g.,
+# you could try to disable your favorite JavaScript annoyances,
+# re-write the actual displayed text, or just have some fun
+# playing buzzword bingo with web pages.
+#
+# The +filter{name} actions rely on the relevant filter (name)
+# to be defined in a filter file!
+#
+# A pre-defined filter file called default.filter that contains a
+# number of useful filters for common problems is included in the
+# distribution. See the section on the filter action for a list.
+#
+# It is recommended to place any locally adapted filters into a
+# separate file, such as user.filter.
+#
+filterfile default.filter
+#filterfile user.filter # User customizations
+#
+#
+# 2.6. logfile
+# =============
+#
+# Specifies:
+#
+# The log file to use
+#
+# Type of value:
+#
+# File name, relative to logdir
+#
+# Default value:
+#
+# Unset (commented out). When activated: logfile (Unix) or
+# privoxy.log (Windows).
+#
+# Effect if unset:
+#
+# No logfile is written.
+#
+# Notes:
+#
+# The logfile is where all logging and error messages are
+# written. The level of detail and number of messages are set with
+# the debug option (see below). The logfile can be useful for
+# tracking down a problem with Privoxy (e.g., it's not blocking
+# an ad you think it should block) and it can help you to monitor
+# what your browser is doing.
+#
+# Depending on the debug options below, the logfile may be a
+# privacy risk if third parties can get access to it. As most
+# users will never look at it, Privoxy 3.0.7 and later only log
+# fatal errors by default.
+#
+# For most troubleshooting purposes, you will have to change that,
+# please refer to the debugging section for details.
+#
+# Your logfile will grow indefinitely, and you will probably
+# want to periodically remove it. On Unix systems, you can do
+# this with a cron job (see "man cron"). For Red Hat based Linux
+# distributions, a logrotate script has been included.
+#
+# Any log files must be writable by whatever user Privoxy is
+# being run as (on Unix, default user id is "privoxy").
+#
+logfile logfile
+#
+#
+# 2.7. trustfile
+# ===============
+#
+# Specifies:
+#
+# The name of the trust file to use
+#
+# Type of value:
+#
+# File name, relative to confdir
+#
+# Default value:
+#
+# Unset (commented out). When activated: trust (Unix) or trust.txt
+# (Windows)
+#
+# Effect if unset:
+#
+# The entire trust mechanism is disabled.
+#
+# Notes:
+#
+# The trust mechanism is an experimental feature for building
+# white-lists and should be used with care. It is NOT recommended
+# for the casual user.
+#
+# If you specify a trust file, Privoxy will only allow access to
+# sites that are specified in the trustfile. Sites can be listed
+# in one of two ways:
+#
+# Prepending a ~ character limits access to this site only (and
+# any sub-paths within this site), e.g. ~www.example.com allows
+# access to ~www.example.com/ features/news.html, etc.
+#
+# Or, you can designate sites as trusted referrers, by prepending
+# the name with a + character. The effect is that access to
+# untrusted sites will be granted -- but only if a link from
+# this trusted referrer was used to get there. The link target
+# will then be added to the "trustfile" so that future, direct
+# accesses will be granted. Sites added via this mechanism do
+# not become trusted referrers themselves (i.e. they are added
+# with a ~ designation). There is a limit of 512 such entries,
+# after which new entries will not be made.
+#
+# If you use the + operator in the trust file, it may grow
+# considerably over time.
+#
+# It is recommended that Privoxy be compiled with the
+# --disable-force, --disable-toggle and --disable-editor options,
+# if this feature is to be used.
+#
+# Possible applications include limiting Internet access for
+# children.
+#
+#trustfile trust
+#
+#
+# 3. DEBUGGING
+# =============
+#
+# These options are mainly useful when tracing a problem. Note that
+# you might also want to invoke Privoxy with the --no-daemon command
+# line option when debugging.
+#
+#
+#
+# 3.1. debug
+# ===========
+#
+# Specifies:
+#
+# Key values that determine what information gets logged.
+#
+# Type of value:
+#
+# Integer values
+#
+# Default value:
+#
+# 0 (i.e.: only fatal errors (that cause Privoxy to exit) are logged)
+#
+# Effect if unset:
+#
+# Default value is used (see above).
+#
+# Notes:
+#
+# The available debug levels are:
+#
+# debug 1 # Log the destination for each request Privoxy let through. See also debug 1024.
+# debug 2 # show each connection status
+# debug 4 # show I/O status
+# debug 8 # show header parsing
+# debug 16 # log all data written to the network into the logfile
+# debug 32 # debug force feature
+# debug 64 # debug regular expression filters
+# debug 128 # debug redirects
+# debug 256 # debug GIF de-animation
+# debug 512 # Common Log Format
+# debug 1024 # Log the destination for requests Privoxy didn't let through, and the reason why.
+# debug 2048 # CGI user interface
+# debug 4096 # Startup banner and warnings.
+# debug 8192 # Non-fatal errors
+#
+#
+# To select multiple debug levels, you can either add them or
+# use multiple debug lines.
+#
+# A debug level of 1 is informative because it will show you each
+# request as it happens. 1, 4096 and 8192 are recommended so that
+# you will notice when things go wrong. The other levels are
+# probably only of interest if you are hunting down a specific
+# problem. They can produce a hell of an output (especially 16).
+#
+# Privoxy used to ship with the debug levels recommended above
+# enabled by default, but due to privacy concerns 3.0.7 and later
+# are configured to only log fatal errors.
+#
+# If you are used to the more verbose settings, simply enable
+# the debug lines below again.
+#
+# If you want to use pure CLF (Common Log Format), you should set
+# "debug 512" ONLY and not enable anything else.
+#
+# Privoxy has a hard-coded limit for the length of log messages. If
+# it's reached, messages are logged truncated and marked with
+# "... [too long, truncated]".
+#
+# Please don't file any support requests without trying to
+# reproduce the problem with increased debug level first. Once
+# you read the log messages, you may even be able to solve the
+# problem on your own.
+#
+#debug 1 # Log the destination for each request Privoxy let through.
+#debug 1024 # Log the destination for requests Privoxy didn't let through, and the reason why.
+#debug 4096 # Startup banner and warnings
+#debug 8192 # Non-fatal errors
+#
+#
+# 3.2. single-threaded
+# =====================
+#
+# Specifies:
+#
+# Whether to run only one server thread.
+#
+# Type of value:
+#
+# None
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# Multi-threaded (or, where unavailable: forked) operation,
+# i.e. the ability to serve multiple requests simultaneously.
+#
+# Notes:
+#
+# This option is only there for debugging purposes. It will
+# drastically reduce performance.
+#
+#single-threaded
+#
+#
+# 3.3. hostname
+# ==============
+#
+# Specifies:
+#
+# The hostname shown on the CGI pages.
+#
+# Type of value:
+#
+# Text
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# The hostname provided by the operating system is used.
+#
+# Notes:
+#
+# On some misconfigured systems resolving the hostname fails or
+# takes too much time and slows Privoxy down. Setting a fixed
+# hostname works around the problem.
+#
+# In other circumstances it might be desirable to show a hostname
+# other than the one returned by the operating system. For example
+# if the system has several different hostnames and you don't
+# want to use the first one.
+#
+# Note that Privoxy does not validate the specified hostname value.
+#
+#hostname hostname.example.org
+#
+#
+# 4. ACCESS CONTROL AND SECURITY
+# ===============================
+#
+# This section of the config file controls the security-relevant
+# aspects of Privoxy's configuration.
+#
+#
+#
+# 4.1. listen-address
+# ====================
+#
+# Specifies:
+#
+# The IP address and TCP port on which Privoxy will listen for
+# client requests.
+#
+# Type of value:
+#
+# [IP-Address]:Port
+#
+# Default value:
+#
+# 127.0.0.1:8118
+#
+# Effect if unset:
+#
+# Bind to 127.0.0.1 (localhost), port 8118. This is suitable and
+# recommended for home users who run Privoxy on the same machine
+# as their browser.
+#
+# Notes:
+#
+# You will need to configure your browser(s) to this proxy address
+# and port.
+#
+# If you already have another service running on port 8118, or
+# if you want to serve requests from other machines (e.g. on your
+# local network) as well, you will need to override the default.
+#
+# If you leave out the IP address, Privoxy will bind to all
+# interfaces (addresses) on your machine and may become reachable
+# from the Internet. In that case, consider using access control
+# lists (ACL's, see below), and/or a firewall.
+#
+# If you open Privoxy to untrusted users, you will also
+# want to make sure that the following actions are disabled:
+# enable-edit-actions and enable-remote-toggle
+#
+# Example:
+#
+# Suppose you are running Privoxy on a machine which has the
+# address 192.168.0.1 on your local private network (192.168.0.0)
+# and has another outside connection with a different address. You
+# want it to serve requests from inside only:
+#
+# listen-address 192.168.0.1:8118
+#
+#
+listen-address 127.0.0.1:8118
+#
+#
+# 4.2. toggle
+# ============
+#
+# Specifies:
+#
+# Initial state of "toggle" status
+#
+# Type of value:
+#
+# 1 or 0
+#
+# Default value:
+#
+# 1
+#
+# Effect if unset:
+#
+# Act as if toggled on
+#
+# Notes:
+#
+# If set to 0, Privoxy will start in "toggled off" mode,
+# i.e. mostly behave like a normal, content-neutral proxy
+# with both ad blocking and content filtering disabled. See
+# enable-remote-toggle below.
+#
+# The windows version will only display the toggle icon in the
+# system tray if this option is present.
+#
+toggle 1
+#
+#
+# 4.3. enable-remote-toggle
+# ==========================
+#
+# Specifies:
+#
+# Whether or not the web-based toggle feature may be used
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# The web-based toggle feature is disabled.
+#
+# Notes:
+#
+# When toggled off, Privoxy mostly acts like a normal,
+# content-neutral proxy, i.e. doesn't block ads or filter content.
+#
+# Access to the toggle feature can not be controlled separately by
+# "ACLs" or HTTP authentication, so that everybody who can access
+# Privoxy (see "ACLs" and listen-address above) can toggle it
+# for all users. So this option is not recommended for multi-user
+# environments with untrusted users.
+#
+# Note that malicious client side code (e.g Java) is also capable
+# of using this option.
+#
+# As a lot of Privoxy users don't read documentation, this feature
+# is disabled by default.
+#
+# Note that you must have compiled Privoxy with support for this
+# feature, otherwise this option has no effect.
+#
+enable-remote-toggle 0
+#
+#
+# 4.4. enable-remote-http-toggle
+# ===============================
+#
+# Specifies:
+#
+# Whether or not Privoxy recognizes special HTTP headers to change
+# its behaviour.
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Privoxy ignores special HTTP headers.
+#
+# Notes:
+#
+# When toggled on, the client can change Privoxy's behaviour by
+# setting special HTTP headers. Currently the only supported
+# special header is "X-Filter: No", to disable filtering for
+# the ongoing request, even if it is enabled in one of the
+# action files.
+#
+# This feature is disabled by default. If you are using Privoxy in
+# a environment with trusted clients, you may enable this feature
+# at your discretion. Note that malicious client side code (e.g
+# Java) is also capable of using this feature.
+#
+# This option will be removed in future releases as it has been
+# obsoleted by the more general header taggers.
+#
+enable-remote-http-toggle 0
+#
+#
+# 4.5. enable-edit-actions
+# =========================
+#
+# Specifies:
+#
+# Whether or not the web-based actions file editor may be used
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# The web-based actions file editor is disabled.
+#
+# Notes:
+#
+# Access to the editor can not be controlled separately by
+# "ACLs" or HTTP authentication, so that everybody who can access
+# Privoxy (see "ACLs" and listen-address above) can modify its
+# configuration for all users.
+#
+# This option is not recommended for environments with untrusted
+# users and as a lot of Privoxy users don't read documentation,
+# this feature is disabled by default.
+#
+# Note that malicious client side code (e.g Java) is also capable
+# of using the actions editor and you shouldn't enable this
+# options unless you understand the consequences and are sure
+# your browser is configured correctly.
+#
+# Note that you must have compiled Privoxy with support for this
+# feature, otherwise this option has no effect.
+#
+enable-edit-actions 0
+#
+#
+# 4.6. enforce-blocks
+# ====================
+#
+# Specifies:
+#
+# Whether the user is allowed to ignore blocks and can "go there
+# anyway".
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Blocks are not enforced.
+#
+# Notes:
+#
+# Privoxy is mainly used to block and filter requests as a service
+# to the user, for example to block ads and other junk that clogs
+# the pipes. Privoxy's configuration isn't perfect and sometimes
+# innocent pages are blocked. In this situation it makes sense to
+# allow the user to enforce the request and have Privoxy ignore
+# the block.
+#
+# In the default configuration Privoxy's "Blocked" page contains
+# a "go there anyway" link to adds a special string (the force
+# prefix) to the request URL. If that link is used, Privoxy
+# will detect the force prefix, remove it again and let the
+# request pass.
+#
+# Of course Privoxy can also be used to enforce a network
+# policy. In that case the user obviously should not be able to
+# bypass any blocks, and that's what the "enforce-blocks" option
+# is for. If it's enabled, Privoxy hides the "go there anyway"
+# link. If the user adds the force prefix by hand, it will not
+# be accepted and the circumvention attempt is logged.
+#
+# Examples:
+#
+# enforce-blocks 1
+#
+enforce-blocks 0
+#
+#
+# 4.7. ACLs: permit-access and deny-access
+# =========================================
+#
+# Specifies:
+#
+# Who can access what.
+#
+# Type of value:
+#
+# src_addr[/src_masklen] [dst_addr[/dst_masklen]]
+#
+# Where src_addr and dst_addr are IP addresses in dotted decimal
+# notation or valid DNS names, and src_masklen and dst_masklen are
+# subnet masks in CIDR notation, i.e. integer values from 2 to 30
+# representing the length (in bits) of the network address. The
+# masks and the whole destination part are optional.
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# Don't restrict access further than implied by listen-address
+#
+# Notes:
+#
+# Access controls are included at the request of ISPs and systems
+# administrators, and are not usually needed by individual
+# users. For a typical home user, it will normally suffice to
+# ensure that Privoxy only listens on the localhost (127.0.0.1)
+# or internal (home) network address by means of the listen-address
+# option.
+#
+# Please see the warnings in the FAQ that Privoxy is not intended
+# to be a substitute for a firewall or to encourage anyone to
+# defer addressing basic security weaknesses.
+#
+# Multiple ACL lines are OK. If any ACLs are specified, Privoxy
+# only talks to IP addresses that match at least one permit-access
+# line and don't match any subsequent deny-access line. In other
+# words, the last match wins, with the default being deny-access.
+#
+# If Privoxy is using a forwarder (see forward below) for a
+# particular destination URL, the dst_addr that is examined is
+# the address of the forwarder and NOT the address of the ultimate
+# target. This is necessary because it may be impossible for the
+# local Privoxy to determine the IP address of the ultimate target
+# (that's often what gateways are used for).
+#
+# You should prefer using IP addresses over DNS names, because
+# the address lookups take time. All DNS names must resolve! You
+# can not use domain patterns like "*.org" or partial domain
+# names. If a DNS name resolves to multiple IP addresses, only
+# the first one is used.
+#
+# Denying access to particular sites by ACL may have undesired
+# side effects if the site in question is hosted on a machine
+# which also hosts other sites (most sites are).
+#
+# Examples:
+#
+# Explicitly define the default behavior if no ACL and
+# listen-address are set: "localhost" is OK. The absence of a
+# dst_addr implies that all destination addresses are OK:
+#
+# permit-access localhost
+#
+#
+# Allow any host on the same class C subnet as www.privoxy.org
+# access to nothing but www.example.com (or other domains hosted
+# on the same system):
+#
+# permit-access www.privoxy.org/24 www.example.com/32
+#
+#
+# Allow access from any host on the 26-bit subnet 192.168.45.64 to
+# anywhere, with the exception that 192.168.45.73 may not access
+# the IP address behind www.dirty-stuff.example.com:
+#
+# permit-access 192.168.45.64/26
+# deny-access 192.168.45.73 www.dirty-stuff.example.com
+#
+#
+#
+# 4.8. buffer-limit
+# ==================
+#
+# Specifies:
+#
+# Maximum size of the buffer for content filtering.
+#
+# Type of value:
+#
+# Size in Kbytes
+#
+# Default value:
+#
+# 4096
+#
+# Effect if unset:
+#
+# Use a 4MB (4096 KB) limit.
+#
+# Notes:
+#
+# For content filtering, i.e. the +filter and +deanimate-gif
+# actions, it is necessary that Privoxy buffers the entire document
+# body. This can be potentially dangerous, since a server could
+# just keep sending data indefinitely and wait for your RAM to
+# exhaust -- with nasty consequences. Hence this option.
+#
+# When a document buffer size reaches the buffer-limit, it is
+# flushed to the client unfiltered and no further attempt to filter
+# the rest of the document is made. Remember that there may be
+# multiple threads running, which might require up to buffer-limit
+# Kbytes each, unless you have enabled "single-threaded" above.
+#
+buffer-limit 4096
+#
+#
+# 5. FORWARDING
+# ==============
+#
+# This feature allows routing of HTTP requests through a chain of
+# multiple proxies.
+#
+# Forwarding can be used to chain Privoxy with a caching proxy to
+# speed up browsing. Using a parent proxy may also be necessary if
+# the machine that Privoxy runs on has no direct Internet access.
+#
+# Note that parent proxies can severely decrease your privacy
+# level. For example a parent proxy could add your IP address to the
+# request headers and if it's a caching proxy it may add the "Etag"
+# header to revalidation requests again, even though you configured
+# Privoxy to remove it. It may also ignore Privoxy's header time
+# randomization and use the original values which could be used by
+# the server as cookie replacement to track your steps between visits.
+#
+# Also specified here are SOCKS proxies. Privoxy supports the SOCKS
+# 4 and SOCKS 4A protocols.
+#
+#
+#
+# 5.1. forward
+# =============
+#
+# Specifies:
+#
+# To which parent HTTP proxy specific requests should be routed.
+#
+# Type of value:
+#
+# target_pattern http_parent[:port]
+#
+# where target_pattern is a URL pattern that specifies to which
+# requests (i.e. URLs) this forward rule shall apply. Use /
+# to denote "all URLs". http_parent[:port] is the DNS name or
+# IP address of the parent HTTP proxy through which the requests
+# should be forwarded, optionally followed by its listening port
+# (default: 8080). Use a single dot (.) to denote "no forwarding".
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# Don't use parent HTTP proxies.
+#
+# Notes:
+#
+# If http_parent is ".", then requests are not forwarded to
+# another HTTP proxy but are made directly to the web servers.
+#
+# Multiple lines are OK, they are checked in sequence, and the
+# last match wins.
+#
+# Examples:
+#
+# Everything goes to an example parent proxy, except SSL on port
+# 443 (which it doesn't handle):
+#
+# forward / parent-proxy.example.org:8080
+# forward :443 .
+#
+#
+# Everything goes to our example ISP's caching proxy, except for
+# requests to that ISP's sites:
+#
+# forward / caching-proxy.isp.example.net:8000
+# forward .isp.example.net .
+#
+#
+#
+#
+# 5.2. forward-socks4, forward-socks4a and forward-socks5
+# ========================================================
+#
+# Specifies:
+#
+# Through which SOCKS proxy (and optionally to which parent HTTP
+# proxy) specific requests should be routed.
+#
+# Type of value:
+#
+# target_pattern socks_proxy[:port] http_parent[:port]
+#
+# where target_pattern is a URL pattern that specifies to which
+# requests (i.e. URLs) this forward rule shall apply. Use / to
+# denote "all URLs". http_parent and socks_proxy are IP addresses
+# in dotted decimal notation or valid DNS names (http_parent may
+# be "." to denote "no HTTP forwarding"), and the optional port
+# parameters are TCP ports, i.e. integer values from 1 to 65535
+#
+# Default value:
+#
+# Unset
+#
+# Effect if unset:
+#
+# Don't use SOCKS proxies.
+#
+# Notes:
+#
+# Multiple lines are OK, they are checked in sequence, and the
+# last match wins.
+#
+# The difference between forward-socks4 and forward-socks4a
+# is that in the SOCKS 4A protocol, the DNS resolution of the
+# target hostname happens on the SOCKS server, while in SOCKS 4
+# it happens locally.
+#
+# With forward-socks5 the DNS resolution will happen on the remote
+# server as well.
+#
+# If http_parent is ".", then requests are not forwarded to another
+# HTTP proxy but are made (HTTP-wise) directly to the web servers,
+# albeit through a SOCKS proxy.
+#
+# Examples:
+#
+# From the company example.com, direct connections are made to all
+# "internal" domains, but everything outbound goes through their
+# ISP's proxy by way of example.com's corporate SOCKS 4A gateway
+# to the Internet.
+#
+# forward-socks4a / socks-gw.example.com:1080 www-cache.isp.example.net:8080
+# forward .example.com .
+#
+#
+# A rule that uses a SOCKS 4 gateway for all destinations but no
+# HTTP parent looks like this:
+#
+# forward-socks4 / socks-gw.example.com:1080 .
+#
+#
+# To chain Privoxy and Tor, both running on the same system,
+# you would use something like:
+#
+# forward-socks4a / 127.0.0.1:9050 .
+#
+#
+# The public Tor network can't be used to reach your local network,
+# if you need to access local servers you therefore might want
+# to make some exceptions:
+#
+# forward 192.168.*.*/ .
+# forward 10.*.*.*/ .
+# forward 127.*.*.*/ .
+#
+#
+# Unencrypted connections to systems in these address ranges will
+# be as (un) secure as the local network is, but the alternative
+# is that you can't reach the local network through Privoxy at
+# all. Of course this may actually be desired and there is no
+# reason to make these exceptions if you aren't sure you need them.
+#
+# If you also want to be able to reach servers in your local
+# network by using their names, you will need additional exceptions
+# that look like this:
+#
+# forward localhost/ .
+#
+#
+#
+#
+# 5.3. forwarded-connect-retries
+# ===============================
+#
+# Specifies:
+#
+# How often Privoxy retries if a forwarded connection request
+# fails.
+#
+# Type of value:
+#
+# Number of retries.
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Connections forwarded through other proxies are treated like
+# direct connections and no retry attempts are made.
+#
+# Notes:
+#
+# forwarded-connect-retries is mainly interesting for socks4a
+# connections, where Privoxy can't detect why the connections
+# failed. The connection might have failed because of a DNS timeout
+# in which case a retry makes sense, but it might also have failed
+# because the server doesn't exist or isn't reachable. In this
+# case the retry will just delay the appearance of Privoxy's
+# error message.
+#
+# Note that in the context of this option, "forwarded connections"
+# includes all connections that Privoxy forwards through other
+# proxies. This option is not limited to the HTTP CONNECT method.
+#
+# Only use this option, if you are getting lots of
+# forwarding-related error messages that go away when you try again
+# manually. Start with a small value and check Privoxy's logfile
+# from time to time, to see how many retries are usually needed.
+#
+# Examples:
+#
+# forwarded-connect-retries 1
+#
+forwarded-connect-retries 0
+#
+#
+# 5.4. accept-intercepted-requests
+# =================================
+#
+# Specifies:
+#
+# Whether intercepted requests should be treated as valid.
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Only proxy requests are accepted, intercepted requests are
+# treated as invalid.
+#
+# Notes:
+#
+# If you don't trust your clients and want to force them to use
+# Privoxy, enable this option and configure your packet filter
+# to redirect outgoing HTTP connections into Privoxy.
+#
+# Make sure that Privoxy's own requests aren't redirected as well.
+# Additionally take care that Privoxy can't intentionally connect
+# to itself, otherwise you could run into redirection loops if
+# Privoxy's listening port is reachable by the outside or an
+# attacker has access to the pages you visit.
+#
+# Examples:
+#
+# accept-intercepted-requests 1
+#
+accept-intercepted-requests 0
+#
+#
+# 5.5. allow-cgi-request-crunching
+# =================================
+#
+# Specifies:
+#
+# Whether requests to Privoxy's CGI pages can be blocked or
+# redirected.
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# Privoxy ignores block and redirect actions for its CGI pages.
+#
+# Notes:
+#
+# By default Privoxy ignores block or redirect actions for
+# its CGI pages. Intercepting these requests can be useful in
+# multi-user setups to implement fine-grained access control,
+# but it can also render the complete web interface useless and
+# make debugging problems painful if done without care.
+#
+# Don't enable this option unless you're sure that you really
+# need it.
+#
+# Examples:
+#
+# allow-cgi-request-crunching 1
+#
+allow-cgi-request-crunching 0
+#
+#
+# 5.6. split-large-forms
+# =======================
+#
+# Specifies:
+#
+# Whether the CGI interface should stay compatible with broken
+# HTTP clients.
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# The CGI form generate long GET URLs.
+#
+# Notes:
+#
+# Privoxy's CGI forms can lead to rather long URLs. This isn't
+# a problem as far as the HTTP standard is concerned, but it can
+# confuse clients with arbitrary URL length limitations.
+#
+# Enabling split-large-forms causes Privoxy to divide big forms
+# into smaller ones to keep the URL length down. It makes editing
+# a lot less convenient and you can no longer submit all changes
+# at once, but at least it works around this browser bug.
+#
+# If you don't notice any editing problems, there is no reason
+# to enable this option, but if one of the submit buttons appears
+# to be broken, you should give it a try.
+#
+# Examples:
+#
+# split-large-forms 1
+#
+split-large-forms 0
+#
+#
+# 5.7. keep-alive-timeout
+# ========================
+#
+# Specifies:
+#
+# Number of seconds after which an open connection will no longer
+# be reused.
+#
+# Type of value:
+#
+# Time in seconds.
+#
+# Default value:
+#
+# None
+#
+# Effect if unset:
+#
+# Connections are not reused.
+#
+# Notes:
+#
+# This option has no effect if Privoxy has been compiled without
+# keep-alive support.
+#
+# Notes:
+#
+# Note that reusing connections doesn't necessary cause
+# speedups. There are also a few privacy implications you should
+# be aware of.
+#
+# Outgoing connections are shared between clients (if there are
+# more than one) and closing the client that initiated the outgoing
+# connection does not affect the connection between Privoxy and
+# the server unless the client's request hasn't been completed
+# yet. If the outgoing connection is idle, it will not be closed
+# until either Privoxy's or the server's timeout is reached. While
+# it's open, the server knows that the system running Privoxy is
+# still there.
+#
+# Examples:
+#
+# keep-alive-timeout 300
+#
+keep-alive-timeout 300
+#
+#
+# 5.8. socket-timeout
+# ====================
+#
+# Specifies:
+#
+# Number of seconds after which a socket times out if no data
+# is received.
+#
+# Type of value:
+#
+# Time in seconds.
+#
+# Default value:
+#
+# None
+#
+# Effect if unset:
+#
+# A default value of 300 seconds is used.
+#
+# Notes:
+#
+# For SOCKS requests the timeout currently doesn't start until
+# the SOCKS server accepted the request. This will be fixed in
+# the next release.
+#
+# Examples:
+#
+# socket-timeout 300
+#
+socket-timeout 300
+#
+#
+# 6. WINDOWS GUI OPTIONS
+# =======================
+#
+# Privoxy has a number of options specific to the Windows GUI
+# interface:
+#
+#
+# If "activity-animation" is set to 1, the Privoxy icon will animate
+# when "Privoxy" is active. To turn off, set to 0.
+#
+#activity-animation 1
+#
+# If "log-messages" is set to 1, Privoxy will log messages to the
+# console window:
+#
+#log-messages 1
+#
+# If "log-buffer-size" is set to 1, the size of the log buffer,
+# i.e. the amount of memory used for the log messages displayed in
+# the console window, will be limited to "log-max-lines" (see below).
+#
+# Warning: Setting this to 0 will result in the buffer to grow
+# infinitely and eat up all your memory!
+#
+#log-buffer-size 1
+#
+# log-max-lines is the maximum number of lines held in the log
+# buffer. See above.
+#
+#log-max-lines 200
+#
+# If "log-highlight-messages" is set to 1, Privoxy will highlight
+# portions of the log messages with a bold-faced font:
+#
+#log-highlight-messages 1
+#
+# The font used in the console window:
+#
+#log-font-name Comic Sans MS
+#
+# Font size used in the console window:
+#
+#log-font-size 8
+#
+# "show-on-task-bar" controls whether or not Privoxy will appear as
+# a button on the Task bar when minimized:
+#
+#show-on-task-bar 0
+#
+# If "close-button-minimizes" is set to 1, the Windows close button
+# will minimize Privoxy instead of closing the program (close with
+# the exit option on the File menu).
+#
+#close-button-minimizes 1
+#
+# The "hide-console" option is specific to the MS-Win console version
+# of Privoxy. If this option is used, Privoxy will disconnect from
+# and hide the command console.
+#
+#hide-console

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ --disable-force Don't allow single-page disable
+ --disable-fast-redirects Don't support fast redirects
+ --disable-stats Don't keep statistics
+ --enable-ie-images Enable a quick but not always reliable auto-detect whether requests from
+ MS Internet Explorer are for an image or not.
+ --disable-image-blocking Don't try to figure out whether a request is
+ for an image or HTML - assume HTML.
+ --disable-acl-files Prevents the use of ACL files to control access to
+ Privoxy by IP address.
+ --disable-trust-files Prevents the use of trust files.
+ --disable-editor Prevents the use of the web-based actions file
+ editor and web-based temporary disable setting.
+ --enable-no-gifs Use politically correct PNG format instead of GIF
+ for built-in images. May not work with all browsers.
+ --enable-graceful-termination Allow to shutdown Privoxy through the webinterface.
+ --enable-extended-host-patterns Allow extended regular expressions in host patterns.
+ --disable-dynamic-pcre Use the built-in, static pcre, even if libpcre is available
+ --disable-zlib Don't use zlib to decompress data before filtering.
+
+Optional Packages:
+ --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
+ --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
+ --with-docbook=yes|no|directory
+ Enable docbook documentation creation
+ (default = yes, for gnu and linux)
+ --with-db2html=<path/executable>
+ Set the location of the docbook to html converter
+ (default = search)
+ --with-debug Enable debug mode
+ --with-user=privoxy Set user under which privoxy will run
+ --with-group=privoxy Set group for privoxy
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.

+dnl Version -> 2.9.5
+dnl
+dnl Revision 1.5 2001/06/29 13:26:27 oes
+dnl Introduced #define CODE_STATUS
+dnl
+dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
+dnl Unified blocklist/imagelist/permissionslist.
+dnl File format is still under discussion, but the internal changes
+dnl are (mostly) done.
+dnl
+dnl Also modified interceptor behaviour:
+dnl - We now intercept all URLs beginning with one of the following
+dnl prefixes (and *only* these prefixes):
+dnl * http://i.j.b/
+dnl * http://ijbswa.sf.net/config/
+dnl * http://ijbswa.sourceforge.net/config/
+dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
+dnl - Internal changes so that intercepted and fast redirect pages
+dnl are not replaced with an image.
+dnl - Interceptors now have the option to send a binary page direct
+dnl to the client. (i.e. ijb-send-banner uses this)
+dnl - Implemented show-url-info interceptor. (Which is why I needed
+dnl the above interceptors changes - a typical URL is
+dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+dnl The previous mechanism would not have intercepted that, and
+dnl if it had been intercepted then it then it would have replaced
+dnl it with an image.)
+dnl
+dnl Revision 1.3 2001/05/22 18:46:04 oes
+dnl
+dnl - Enabled filtering banners by size rather than URL
+dnl by adding patterns that replace all standard banner
+dnl sizes with the "Junkbuster" gif to the re_filterfile
+dnl
+dnl - Enabled filtering WebBugs by providing a pattern
+dnl which kills all 1x1 images
+dnl
+dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
+dnl which is selected by the (nonstandard and therefore
+dnl capital) letter 'U' in the option string.
+dnl It causes the quantifiers to be ungreedy by default.
+dnl Appending a ? turns back to greedy (!).
+dnl
+dnl - Added a new interceptor ijb-send-banner, which
+dnl sends back the "Junkbuster" gif. Without imagelist or
+dnl MSIE detection support, or if tinygif = 1, or the
+dnl URL isn't recognized as an imageurl, a lame HTML
+dnl explanation is sent instead.
+dnl
+dnl - Added new feature, which permits blocking remote
+dnl script redirects and firing back a local redirect
+dnl to the browser.
+dnl The feature is conditionally compiled, i.e. it
+dnl can be disabled with --disable-fast-redirects,
+dnl plus it must be activated by a "fast-redirects"
+dnl line in the config file, has its own log level
+dnl and of course wants to be displayed by show-proxy-args
+dnl Note: Boy, all the #ifdefs in 1001 locations and
+dnl all the fumbling with configure.in and acconfig.h
+dnl were *way* more work than the feature itself :-(
+dnl
+dnl - Because a generic redirect template was needed for
+dnl this, tinygif = 3 now uses the same.
+dnl
+dnl - Moved GIFs, and other static HTTP response templates
+dnl to project.h
+dnl
+dnl - Some minor fixes
+dnl
+dnl - Removed some >400 CRs again (Jon, you really worked
+dnl a lot! ;-)
+dnl
+dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
+dnl Version 2.9.4 checkin.
+dnl - Merged popupfile and cookiefile, and added control over PCRS
+dnl filtering, in new "permissionsfile".
+dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+dnl file error you now get a message box (in the Win32 GUI) rather
+dnl than the program exiting with no explanation.
+dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
+dnl skipping.
+dnl - Removed tabs from "config"
+dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+dnl - Bumped up version number.

+#############################################################################
+# Syntax
+#############################################################################
+#
+# A much better explanation can be found in the user manual which is
+# part of the distribution and can be found at http://www.privoxy.org/user-manual
+#
+# To determine which actions apply to a request, the URL of the request is
+# compared to all patterns in this file. Every time it matches, the list of
+# applicable actions for this URL is incrementally updated. You can trace
+# this process by visiting http://config.privoxy.org/show-url-info
+#
+# There are 4 types of lines in this file: comments (like this line),
+# actions, aliases and patterns, all of which are explained below.
+#
+#############################################################################
+# Pattern Syntax
+#############################################################################
+#
+# 1. On Domains and Paths
+# -----------------------
+#
+# Generally, a pattern has the form <domain>/<path>, where both the <domain>
+# and <path> part are optional. The pattern matching syntax is different for
+# each. If you only specify a domain part, the "/" can be left out, but it is
+# required for the path part.
+#
+# www.example.com
+# is a domain-only pattern and will match any request to www.example.com
+#
+# www.example.com/
+# means exactly the same (but is slightly less efficient)
+#
+# www.example.com/index.html
+# matches only the document /index.html on www.example.com
+#
+# /index.html
+# matches the document /index.html, regardless of the domain
+#
+# index.html
+# matches nothing, since it would be interpreted as a domain name and
+# there is no top-level domain called ".html".
+#
+# 2. Domain Syntax
+# ----------------
+#
+# The matching of the domain part offers some flexible options: If the
+# domain starts or ends with a dot, it becomes unanchored at that end:
+#
+# www.example.com
+# matches only www.example.com
+#
+# .example.com
+# matches any domain that ENDS in .example.com
+#
+# www.
+# matches any domain that STARTS with www.
+#
+# .example.
+# matches any domain that CONTAINS example
+#
+#
+# Additionally, there are wildcards that you can use in the domain names
+# themselves. They work pretty similar to shell wildcards: "*" stands for
+# zero or more arbitrary characters, "?" stands for one, and you can define
+# character classes in square brackets and they can be freely mixed:
+#
+# ad*.example.com
+# matches adserver.example.com, ads.example.com, etc but not sfads.example.com
+#
+# *ad*.example.com
+# matches all of the above
+#
+# .?pix.com
+# matches www.ipix.com, pictures.epix.com, a.b.c.d.e.upix.com etc
+#
+# www[1-9a-ez].example.com
+# matches www1.example.com, www4.example.com, wwwd.example.com,
+# wwwz.example.com etc, but not wwww.example.com
+#
+# You get the idea?
+#
+# 2. Path Syntax
+# --------------
+#
+# Paths are specified as full regular expressions, and are more flexible than
+# the domain syntax above. A comprehensive discussion of regular expressions
+# wouldn't fit here.
+#
+# Perl compatible regular expressions are used. See the pcre/docs/ direcory or
+# man perlre (also available at http://perldoc.perl.org/perlre.html) for
+# details. The appendix to our User Manual also has some detail.
+#
+# Please note that matching in the path is CASE INSENSITIVE by default, but
+# you can switch to case sensitive by starting the pattern with the "(?-i)"
+# switch:
+#
+# www.example.com/(?-i)PaTtErN.*
+# will match only documents whose path starts with PaTtErN in exactly this
+# capitalization.
+#
+# Partially case-sensitive and partially case-insensitive patterns are
+# possible, but the rules about splitting them up are extremely complex
+# - see the PCRE documentation for more information.
+#
+#############################################################################
+# Action Syntax
+#############################################################################
+#
+# There are 3 kinds of actions:
+#
+# Boolean (e.g. "handle-as-image"):
+# +name # enable
+# -name # disable
+#
+# Parameterized (e.g. "hide-user-agent"):
+# +name{param} # enable and set parameter to "param"
+# -name # disable
+#
+# Multi-value (e.g. "add-header", "filter"):
+# +name{param} # enable and add parameter "param"
+# -name{param} # remove the parameter "param"
+# -name # disable totally
+#
+# The default (if you don't specify anything in this file) is not to take
+# any actions - i.e completely disabled, so Privoxy will just be a
+# normal, non-blocking, non-anonymizing proxy. You must specifically
+# enable the privacy and blocking features you need (although the
+# provided default actions file will do that for you).
+#
+# Later actions always override earlier ones. For multi-valued actions,
+# the actions are applied in the order they are specified.
+#
+#############################################################################
+# Valid actions are:
+#############################################################################
+#
+# +add-header{Name: value}
+# Adds the specified HTTP header, which is not checked for validity.
+# You may specify this many times to specify many headers.
+#
+# +block{reason}
+# Block this URL. Instead of forwarding the request, Privoxy will
+# send a "block" page containing the specified reason.
+#
+# +change-x-forwarded-for{add}
+# +change-x-forwarded-for{block}
+# Adds or blocks the "X-Forwarded-For:" HTTP header in client
+# requests.
+#
+# +client-header-filter{name}
+# All client headers to which this action applies are filtered on-the-fly
+# through the specified regular expression based substitutions.
+#
+# Client-header filters predefined in the supplied default.filter include:
+#
+# hide-tor-exit-notation: Removes the Tor exit node notation in Host and Referer headers.
+# privoxy-control: Removes X-Privoxy-Control headers.
+#
+# +client-header-tagger{string}
+# Tag requests based on their headers. Client headers to which this
+# action applies are filtered on-the-fly through the specified regular
+# expression based substitutions, the result is used as a tag.
+# Client-header taggers are the first actions that are executed and their
+# tags can be used to control every other action.
+#
+# Client-header taggers predefined in the supplied default.filter include:
+#
+# image-requests: Tags detected image requests as "IMAGE-REQUEST".
+# css-requests: Tags detected CSS requests as "CSS-REQUEST".
+# client-ip-address: Tags the request with the client's IP address.
+# http-method: Tags the request with its HTTP method.
+# allow-post: Tags POST requests as "ALLOWED-POST".
+# complete-url: Tags the request with the whole request URL.
+# user-agent: Tags the request with the complete User-Agent header.
+# privoxy-control: Creates tags with the content of X-Privoxy-Control headers.
+#
+# +content-type-overwrite
+# Replaces the "Content-Type:" HTTP server header, so that unwanted
+# download menus will not pop up, or changes the browser's rendering mode.
+#
+# +crunch-client-header{string}
+# Deletes every header sent by the client that contains the string the
+# user supplied as parameter.
+#
+# +crunch-if-none-match
+# Deletes the "If-None-Match:" HTTP client header.
+#
+# +crunch-server-header{string}
+# Deletes every header sent by the server that contains the string the
+# user supplied as a parameter.
+#
+# +deanimate-gifs{last}
+# +deanimate-gifs{first}
+# Deanimate all animated GIF images, i.e. reduce them to their last
+# frame. This will also shrink the images considerably. (In bytes,
+# not pixels!)
+# If the option "first" is given, the first frame of the animation
+# is used as the replacement. If "last" is given, the last frame of
+# the animation is used instead, which propably makes more sense for
+# most banner animations, but also has the risk of not showing the
+# entire last frame (if it is only a delta to an earlier frame).
+#
+# +downgrade-http-version
+# Downgrade HTTP/1.1 client requests to HTTP/1.0 and downgrade the
+# responses as well. Use this action for servers that use HTTP/1.1
+# protocol features that Privoxy currently can't handle yet.
+#
+# +fast-redirects{check-decoded-url}
+# +fast-redirects{simple-check}
+# Many sites, like yahoo.com, don't just link to other sites.
+# Instead, they will link to some script on their own server,
+# giving the destination as a parameter, which will then redirect
+# you to the final target.
+#
+# URLs resulting from this scheme typically look like:
+# http://some.place/some_script?http://some.where-else
+#
+# Sometimes, there are even multiple consecutive redirects encoded
+# in the URL. These redirections via scripts make your web browsing
+# more traceable, since the server from which you follow such a link
+# can see where you go to. Apart from that, valuable bandwidth and
+# time is wasted, while your browser asks the server for one redirect
+# after the other. Plus, it feeds the advertisers.
+#
+# The +fast-redirects{check-decoded-url} option enables interception of
+# these requests by Privoxy, who will cut off all but the last valid URL
+# in the request and send a local redirect back to your browser without
+# contacting the intermediate sites. NOTE: Syntax change as of v.3.0.4.
+#
+# +filter{name}
+# All files of text-based type, most notably HTML and JavaScript, to which
+# this action applies, can be filtered on-the-fly through the specified
+# regular expression based substitutions. (Note: plain text documents are
+# exempted from filtering, because web servers often use the text/plain
+# MIME type for all files whose type they don't know.) By default,
+# filtering works only on the raw document content itself (that which can
+# be seen with View Source), not the headers. Repeat for multiple filters.
+# Use with caution: filters can be very intrusive.
+#
+# Filters predefined in the supplied default.filter include:
+#
+# js-annoyances: Get rid of particularly annoying JavaScript abuse.
+# js-events: Kill all JS event bindings and timers (Radically destructive! Only for extra nasty sites).
+# html-annoyances: Get rid of particularly annoying HTML abuse.
+# content-cookies: Kill cookies that come in the HTML or JS content.
+# refresh-tags: Kill automatic refresh tags (for dial-on-demand setups).
+# unsolicited-popups: Disable only unsolicited pop-up windows.
+# all-popups: Kill all popups in JavaScript and HTML.
+# img-reorder: Reorder attributes in <img> tags to make the banners-by-* filters more effective.
+# banners-by-size: Kill banners by size.
+# banners-by-link: Kill banners by their links to known clicktrackers.
+# webbugs: Squish WebBugs (1x1 invisible GIFs used for user tracking).
+# tiny-textforms: Extend those tiny textareas up to 40x80 and kill the hard wrap.
+# jumping-windows: Prevent windows from resizing and moving themselves.
+# frameset-borders: Give frames a border and make them resizable.
+# demoronizer: Fix MS's non-standard use of standard charsets.
+# shockwave-flash: Kill embedded Shockwave Flash objects.
+# quicktime-kioskmode: Make Quicktime movies saveable.
+# fun: Text replacements for subversive browsing fun!
+# crude-parental: Crude parental filtering. Note that this filter doesn't work reliably.
+# ie-exploits: Disable some known Internet Explorer bug exploits.
+# site-specifics: Cure for site-specific problems. Don't apply generally!
+# no-ping: Removes non-standard ping attributes in <a> and <area> tags.
+# google: CSS-based block for Google text ads. Also removes a width limitation and the toolbar advertisement.
+# yahoo: CSS-based block for Yahoo text ads. Also removes a width limitation.
+# msn: CSS-based block for MSN text ads. Also removes tracking URLs and a width limitation.
+# blogspot: Cleans up some Blogspot blogs. Read the fine print before using this.
+#
+# +force-text-mode
+# Declares a document as plain text, even if the "Content-Type:" isn't detected
+# as such.
+#
+# +forward-override{forward .}
+# +forward-override{forward 127.0.0.1:8123}

+# +forward-override{forward-socks5 127.0.0.1:9050 proxy.example.org:8000}
+# This action overrules the forward directives in the configuration file.
+#
+# +handle-as-empty-document
+# This action alone doesn't do anything noticeable. It just marks URLs. If
+# the block action also applies, the presence or absence of this mark
+# decides whether an HTML "blocked" page, or an empty document will be sent
+# to the client as a substitute for the blocked content.
+#
+# +handle-as-image
+# Treat this URL as an image. This only matters if it's also "+block"ed,
+# in which case a "blocked" image can be sent rather than a HTML page.
+# See +set-image-blocker{} for the control over what is actually sent.
+#
+# +hide-accept-language{lang}
+# +hide-accept-language{block}
+# Deletes or replaces the "Accept-Language:" HTTP header in client
+# requests.
+#
+# +hide-content-disposition{block}
+# +hide-content-disposition{string}
+# Deletes or replaces the "Content-Disposition:" HTTP header set by some
+# servers. This can be used to prevent download menus for content you
+# prefer to view inside the browser, for example.
+#
+# +hide-from-header{block}
+# +hide-from-header{spam(a)sittingduck.xqq}
+# If the browser sends a "From:" header containing your e-mail address,
+# either completely removes the header ("block"), or change it to the
+# specified e-mail address.
+#
+# +hide-if-modified-since{block}
+# +hide-if-modified-since{-60}
+# Deletes the "If-Modified-Since:" HTTP client header or modifies its
+# value, preventing another way to track users.
+#
+# +hide-referer{block}
+# +hide-referer{forge}
+# +hide-referer{http://nowhere.com}
+# Don't send the "Referer:" (sic) header to the web site. You can
+# block it, forge a URL to the same server as the request (which is
+# preferred because some sites will not send images otherwise) or
+# set it to a constant string.
+#
+# +hide-referrer{...}
+# Alternative spelling of +hide-referer. Has the same parameters,
+# and can be freely mixed with, "+hide-referer". ("referrer" is the
+# correct English spelling, however the HTTP specification has a
+# bug - it requires it to be spelt "referer").
+#
+# +hide-user-agent{browser-type}
+# Change the "User-Agent:" header so web servers can't tell your
+# browser type. (Breaks many web sites). Specify the user-agent
+# value you want - e.g., to pretend to be using Netscape on Linux:
+# +hide-user-agent{Mozilla (X11; I; Linux 2.0.32 i586)}
+# Or to identify yourself explicitly as a Privoxy user:
+# +hide-user-agent{Privoxy/1.0}
+# (Don't change the version number from 1.0 - after all, why tell them?)
+#
+# +limit-connect{portlist}
+#
+# By default, i.e. if no limit-connect action applies, Privoxy
+# allows HTTP CONNECT requests to all ports. Use limit-connect
+# if fine-grained control is desired for some or all destinations.
+# The CONNECT methods exists in HTTP to allow access to secure websites
+# ("https://" URLs) through proxies. It works very simply: the proxy
+# connects to the server on the specified port, and then short-circuits
+# its connections to the client and to the remote server. This means
+# CONNECT-enabled proxies can be used as TCP relays very easily. Privoxy
+# relays HTTPS traffic without seeing the decoded content. Websites can
+# leverage this limitation to circumvent Privoxy's filters. By specifying
+# an invalid port range you can disable HTTPS entirely.
+#
+# +limit-connect{443} # Only port 443 is OK.
+# +limit-connect{80,443} # Ports 80 and 443 are OK.
+# +limit-connect{-3, 7, 20-100, 500-} # Ports less than 3, 7, 20 to 100 and above 500 are OK.
+# +limit-connect{-} # All ports are OK
+# +limit-connect{,} # No HTTPS/SSL traffic is allowed
+#
+# +overwrite-last-modified{block}
+# +overwrite-last-modified{reset-to-request-time}
+# +overwrite-last-modified{randomize}
+# Removing the "Last-Modified:" header is useful for filter testing, where
+# you want to force a real reload instead of getting status code "304",
+# which would cause the browser to reuse the old version of the page.
+#
+# The "randomize" option overwrites the value of the "Last-Modified:"
+# header with a randomly chosen time between the original value and the
+# current time. In theory the server could send each document with a
+# different "Last-Modified:" header to track visits without using cookies.
+# "Randomize" makes it impossible and the browser can still revalidate
+# cached documents.
+#
+# "reset-to-request-time" overwrites the value of the "Last-Modified:"
+# header with the current time. You could use this option together with
+# hide-if-modified-since to further customize your random range.
+#
+# +prevent-compression
+# Prevent the website from compressing the data. Some websites do
+# that, which is a problem for Privoxy when built without zlib support,
+# since +filter and +gif-deanimate will not work on compressed data.
+# Will slow down connections to those websites, though.
+#
+# +server-header-filter{name}
+# All server headers to which this action applies are filtered on-the-fly
+# through the specified regular expression based substitutions.
+#
+# Server-header filters predefined in the supplied default.filter include:
+#
+# x-httpd-php-to-html: Changes the Content-Type header from x-httpd-php to html.
+# html-to-xml: Changes the Content-Type header from html to xml.
+# xml-to-html: Changes the Content-Type header from xml to html.
+# less-download-windows: Prevent annoying download windows for content types the browser can handle itself.
+# privoxy-control: Removes X-Privoxy-Control headers.
+#
+# +server-header-tagger{content-type}
+# Server headers to which this action applies are filtered on-the-fly
+# through the specified regular expression based substitutions, the result
+# is used as a tag. Server-header taggers are executed before all other
+# header actions that modify server headers. Their tags can be used to
+# control all of the other server-header actions, the content filters and
+# the crunch actions (redirect and block).
+#
+# Server-header taggers predefined in the supplied default.filter include:
+#
+# content-type: Tags the request with the content type declared by the server.
+# privoxy-control: Creates tags with the content of X-Privoxy-Control headers.
+#
+# +session-cookies-only
+# If the website sets cookies, make sure they are erased when you exit
+# and restart your web browser. This makes profiling cookies useless,
+# but won't break sites which require cookies so that you can log in
+# or for transactions.
+#
+# +set-image-blocker{blank}
+# +set-image-blocker{pattern}
+# +set-image-blocker{<URL>} with <url> being any valid image URL
+# Decides what to do with URLs that end up tagged with {+block +handle-as-image}.
+# There are 4 options:
+# * "-set-image-blocker" will send a HTML "blocked" page, usually
+# resulting in a "broken image" icon.
+# * "+set-image-blocker{blank}" will send a 1x1 transparent image
+# * "+set-image-blocker{pattern}" will send a 4x4 grey/white pattern
+# which is less intrusive than the logo but easier to recognize
+# than the transparent one.
+# * "+set-image-blocker{<URL>}" will send a HTTP temporary redirect
+# to the specified image URL.
+#
+#
+# +crunch-outgoing-cookies
+# Prevent the website from reading cookies
+#
+# +crunch-incoming-cookies
+# Prevent the website from setting cookies
+#
+# +redirect{<URL>}
+# +redirect{<pcrs command>}
+# Convinces the browser that the requested document has been moved to
+# another location and the browser should get it from the specified
+# URL.

+#################################################################################
+#
+# Syntax:
+#
+# Generally filters start with a line like "FILTER: name description".
+# They are then referrable from the actionsfile with +filter{name}
+#
+# FILTER marks a filter as content filter, other filter
+# types are CLIENT-HEADER-FILTER, CLIENT-HEADER-TAGGER,
+# SERVER-HEADER-FILTER and SERVER-HEADER-TAGGER.
+#
+# Inside the filters, write one Perl-Style substitution (job) per line.
+# Jobs that precede the first FILTER: line are ignored.
+#
+# For Details see the pcrs manpage contained in this distribution.
+# (and the perlre, perlop and pcre manpages)
+#
+# Note that you are free to choose the delimiter as you see fit.
+#
+# Note2: In addition to the Perl options gimsx, the following nonstandard
+# options are supported:
+#
+# 'U' turns the default to ungreedy matching. Add ? to quantifiers to
+# switch back to greedy.
+#
+# 'T' (trivial) prevents parsing for backreferences in the substitute.
+# Use if you want to include text like '$&' in your substitute without
+# quoting.
+#
+# 'D' (Dynamic) allows the use of variables. Supported variables are:
+# $host, $origin (the IP address the request came from), $path and $url.
+#
+# Note that '$' is a bad choice as delimiter for dynamic filters as you
+# might end up with unintended variables if you use a variable name
+# directly after the delimiter. Variables will be resolved without
+# escaping anything, therefore you also have to be careful not to chose
+# delimiters that appear in the replacement text. For example '<' should
+# be save, while '?' will sooner or later cause conflicts with $url.

+# Modified webbugs filter to create a comment around the offending

+# Adjusted regex to only match if there's at least one whitespace

+ "fb.gif" alt="*"></a> Preamble</h3>
+
+ <p>The licenses for most software are designed to take away
+ your freedom to share and change it. By contrast, the GNU
+ General Public License is intended to guarantee your freedom to
+ share and change free software--to make sure the software is
+ free for all its users. This General Public License applies to
+ most of the Free Software Foundation's software and to any
+ other program whose authors commit to using it. (Some other
+ Free Software Foundation software is covered by the GNU Library
+ General Public License instead.) You can apply it to your
+ programs, too.</p>
+
+ <p><a name="freedom">When we speak of free software,</a> we are
+ referring to freedom, not price. Our General Public Licenses
+ are designed to make sure that you have the freedom to
+ distribute copies of free software (and charge for this service
+ if you wish), that you receive source code or can get it if you
+ want it, that you can change the software or use pieces of it
+ in new free programs; and that you know you can do these
+ things.</p>
+
+ <p><a name="forbid">To protect your rights,</a> we need to make
+ restrictions that forbid anyone to deny you these rights or to
+ ask you to surrender the rights. These restrictions translate
+ to certain responsibilities for you if you distribute copies of
+ the software, or if you modify it.</p>
+
+ <p><a name="allrights">For example,</a> if you distribute
+ copies of such a program, whether gratis or for a fee, you must
+ give the recipients all the rights that you have. You must make
+ sure that they, too, receive or can get the source code. And
+ you must show them these terms so they know their rights.</p>
+
+ <p><a name="steps">We protect your rights with two steps:</a>
+ (1) copyright the software, and (2) offer you this license
+ which gives you legal permission to copy, distribute and/or
+ modify the software.</p>
+
+ <p><a name="protection">Also,</a> for each author's protection
+ and ours, we want to make certain that everyone understands
+ that there is no warranty for this free software. If the
+ software is modified by someone else and passed on, we want its
+ recipients to know that what they have is not the original, so
+ that any problems introduced by others will not reflect on the
+ original authors' reputations.</p>
+
+ <p><a name="threat">Finally,</a> any free program is threatened
+ constantly by software patents. We wish to avoid the danger
+ that redistributors of a free program will individually obtain
+ patent licenses, in effect making the program proprietary. To
+ prevent this, we have made it clear that any patent must be
+ licensed for everyone's free use or not licensed at all.</p>
+
+ <p><a name="terms">The precise terms and conditions</a> for
+ copying, distribution and modification follow.</p>
+
+ <h3><a name="tnc"><img border="0" width="14" height="14" src=
+ "fb.gif" alt="*"></a> GNU General Public License: Terms
+ and Conditions for Copying, Distribution and Modification</h3>
+
+ <p><a name="applies">O.</a> This License applies to any program
+ or other work which contains a notice placed by the copyright
+ holder saying it may be distributed under the terms of this
+ General Public License. The "Program", below, refers to any
+ such program or work, and a "work based on the Program" means
+ either the Program or any derivative work under copyright law:
+ that is to say, a work containing the Program or a portion of
+ it, either verbatim or with modifications and/or translated
+ into another language. (Hereinafter, translation is included
+ without limitation in the term "modification".) Each licensee
+ is addressed as "you".</p>
+
+ <p><a name="scope">Activities</a> other than copying,
+ distribution and modification are not covered by this License;
+ they are outside its scope. The act of running the Program is
+ not restricted, and the output from the Program is covered only
+ if its contents constitute a work based on the Program
+ (independent of having been made by running the Program).</p>
+
+ <p><a name="depends">Whether that is true depends on what the
+ Program does.</a><br>
+ </p>
+
+ <ol type="1">
+ <li>
+ <a name="verbatim">You may copy</a> and distribute verbatim
+ copies of the Program's source code as you receive it, in
+ any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright
+ notice and disclaimer of warranty; keep intact all the
+ notices that refer to this License and to the absence of
+ any warranty; and give any other recipients of the Program
+ a copy of this License along with the Program.
+
+ <p><a name="fee">You may charge a fee</a> for the physical
+ act of transferring a copy, and you may at your option
+ offer warranty protection in exchange for a fee.</p>
+ </li>
+
+ <li>
+ <a name="modify">You may modify</a> your copy or copies of
+ the Program or any portion of it, thus forming a work based
+ on the Program, and copy and distribute such modifications
+ or work under the terms of Section 1 above, provided that
+ you also meet all of these conditions:<br>
+
+
+ <ol type="a">
+ <li><a name="notices">You must cause</a> the modified
+ files to carry prominent notices stating that you changed
+ the files and the date of any change.</li>
+
+ <li><a name="nocharge">You must</a> cause any work that
+ you distribute or publish, that in whole or in part
+ contains or is derived from the Program or any part
+ thereof, to be licensed as a whole at no charge to all
+ third parties under the terms of this License.</li>
+
+ <li><a name="interactive">If the modified program</a>
+ normally reads commands interactively when run, you must
+ cause it, when started running for such interactive use
+ in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice
+ and a notice that there is no warranty (or else, saying
+ that you provide a warranty) and that users may
+ redistribute the program under these conditions, and
+ telling the user how to view a copy of this License.
+ (Exception: if the Program itself is interactive but does
+ not normally print such an announcement, your work based
+ on the Program is not required to print an
+ announcement.)</li>
+ </ol>
+
+ <p><a name="sections">These requirements</a> apply to the
+ modified work as a whole. If identifiable sections of that
+ work are not derived from the Program, and can be
+ reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply
+ to those sections when you distribute them as separate
+ works. But when you distribute the same sections as part of
+ a whole which is a work based on the Program, the
+ distribution of the whole must be on the terms of this
+ License, whose permissions for other licensees extend to
+ the entire whole, and thus to each and every part
+ regardless of who wrote it.</p>
+
+ <p><a name="intent">Thus,</a> it is not the intent of this
+ section to claim rights or contest your rights to work
+ written entirely by you; rather, the intent is to exercise
+ the right to control the distribution of derivative or
+ collective works based on the Program.</p>
+
+ <p><a name="aggregation">In addition,</a> mere aggregation
+ of another work not based on the Program with the Program
+ (or with a work based on the Program) on a volume of a
+ storage or distribution medium does not bring the other
+ work under the scope of this License.</p>
+ </li>
+
+ <li>

+.SH DESCRIPTION
+
+The
+.SM PCRS
+library is a supplement to the
+.SB PCRE(3)
+library that implements
+.RB "regular expression based substitution, like provided by " Perl(1) "'s 's'"
+operator. It uses the same syntax and semantics as Perl 5, with just a few
+differences (see below).
+
+In a first step, the information on a substitution, i.e. the pattern, the
+substitute and the options are compiled from Perl syntax to an internal form
+.RB "called " pcrs_job " by using either the " pcrs_compile() " or "
+.BR pcrs_compile_command() " functions."
+
+Once the job is compiled, it can be used on subjects, which are arbitrary
+memory areas containing string or binary data, by calling
+.BR pcrs_execute() ". Jobs can be chained to joblists and whole"
+.RB "joblists can be applied to a subject using " pcrs_execute_list() .
+
+There are also convenience functions for freeing the jobs and for errno-to-string
+.RB "conversion, namely " pcrs_free_job() ", " pcrs_free_joblist() " and "
+.BR pcrs_strerror() .
+
+.SH COMPILING JOBS
+
+.RB "The function " pcrs_compile() " is called to compile a " pcrs_job
+.RI "from a " pattern ", " substitute " and " options " string."
+.RB "The resulting " "pcrs_job" " structure is dynamically allocated and it"
+.RB "is the caller's responsibility to call " "pcrs_free_job()" " when it's no longer needed."
+
+.BR "pcrs_compile_command()" " is a convenience wrapper function that parses a Perl"
+.IR "command" " of the form"
+.BI "s/" "pattern" "/" "substitute" "/[" "options" "]"
+.RB "into its components and then calls " "pcrs_compile()" ". As in Perl, you"
+.RB "are not bound to the '" "/" "' character: Whatever"
+.RB "follows the '" "s" "' will be used as the delimiter. Patterns or substitutes"
+that contain the delimiter need to quote it:
+\fBs/th\\/is/th\\/at/\fR
+.RB "will replace " "th/is" " by " "th/at" " and can be written more simply as"
+.BR "s|th/is|th/at|" "."
+
+.IR "pattern" ", " "substitute" ", " "options" " and " "command" " must be"
+.RI "zero-terminated C strings. " "substitute" " and " "options" " may be"
+.BR "NULL" ", in which case they are treated like the empty string."
+
+.SS "Return value and diagnostics"
+On success, both functions return a pointer to the compiled job.
+.RB "On failure, " "NULL"
+.RI "is returned. In that case, the pcrs error code is written to *" "err" "."
+
+.SS Patterns
+.RI "For the syntax of the " "pattern" ", see the "
+.BR "PCRE(3)" " manual page."
+
+.SS Substitutes
+.RI "The " "substitute" " uses"
+.RB "Perl syntax as documented in the " "perlre(1)" " manual page, with"
+some exceptions:
+
+Most notably and evidently, since
+.SM PCRS
+is not Perl, variable interpolation or Perl command substitution won't work.
+Special variables that do get interpolated, are:
+.TP
+.B "$1, $2, ..., $n"
+Like in Perl, these variables refer to what the nth capturing subpattern
+in the pattern matched.
+.TP
+.B "$& and $0"
+.RB "refer to the whole match. Note that " "$0" " is deprecated in recent"
+Perl versions and now refers to the program name.
+.TP
+.B "$+"
+refers to what the last capturing subpattern matched.
+.TP
+.BR "$` and $'" " (backtick and tick)"
+.RI "refer to the areas of the " "subject" " before and after the match, respectively."
+.RB "Note that, like in Perl, the " "unmodified" " subject is used, even"
+if a global substitution previously matched.
+
+.PP
+Perl4-style references to subpattern matches of the form
+\fB\\1, \\2, ...\fR
+.RB "which only exist in Perl5 for backwards compatibility, are " "not"
+supported.
+
+Also, since the substitute is a double-quoted string in Perl, you
+might expect all Perl syntax for special characters to apply. In fact,
+only the following are supported:
+
+.TP
+\fB\\n\fR
+newline (0x0a)
+.TP
+\fB\\r\fR
+carriage return (0x0d)
+.TP
+\fB\\t\fR
+horizontal tab (0x09)
+.TP
+\fB\\f\fR
+form feed (0x0c)
+.TP
+\fB\\b\fR
+backspace (0x08)
+.TP
+\fB\\a\fR
+alarm, bell (0x07)
+.TP
+\fB\\e\fR
+escape (0x1b)
+.TP
+\fB\\0\fR
+binary zero (0x00)
+
+.SS "Options"
+.RB "The options " "gmisx" " are supported. " "e" " is not, since it would"
+.RB "require a Perl interpreter and neither is " o ", because the pattern
+is explicitly compiled, anyway. Additionally,
+.SM PCRS
+.RB "honors the options " "U" " and " "T" "."
+Where
+.SM PCRE
+.RB "options are mentioned below, refer to " PCRE(3) " for the subtle differences"
+to Perl behaviour.
+
+.TP
+.B g
+.RB "Replace " all " instances of"
+.IR pattern " in " subject ,
+not just the first one.
+
+.TP
+.B i
+.RI "Match the " pattern " without respect to case. This translates to"
+.SM PCRE_CASELESS.
+
+.TP
+.B m
+.RI "Treat the " subject " as consisting of multiple lines, i.e."
+.RB ' ^ "' matches immediately after, and '" $ "' immediately before each newline."
+Translates to
+.SM PCRE_MULTILINE.
+
+.TP
+.B s
+.RI "Treat the " subject " as consisting of one single line, i.e."
+.RB "let the scope of the '" . "' metacharacter include newlines."
+Translates to
+.SM PCRE_DOTALL.
+
+.TP
+.B x
+.RI "Allow extended regular expression syntax in the " pattern ","
+.RB "enabling whitespace and comments in complex patterns."
+Translates to
+.SM PCRE_EXTENDED.
+
+.TP
+.B U
+.RB "Switch the default behaviour of the '" * "' and '" + "' quantifiers"
+.RB "to ungreedy. Note that appending a '" ? "' switches back to greedy(!)."
+.RB "The explicit in-pattern switches " (?U) " and " (?-U) " remain unaffected."
+Translates to
+.SM PCRE_UNGREEDY.
+
+.TP
+.B T
+.RI "Consider the " substitute " trivial, i.e. do not interpret any references"
+or special character escape sequences in the substitute. Handy for large
+user-supplied substitutes, which would otherwise have to be examined and properly
+quoted.
+
+.PP
+Unsupported options are silently ignored.
+
+.SH EXECUTING JOBS
+
+.RI "Calling " pcrs_execute() " produces a modified copy of the " subject ", in which"
+.RB "the first (or all, if the '" g "' option was given when compiling the job)"
+.RI "occurance(s) of the job's " pattern " in the " subject " is replaced by the job's"
+.IR substitute .
+
+.RI "The first " subject_length " bytes following " subject " are processed, so"
+.RI "a " subject_length " that exceeds the actual " subject " is dangerous."
+.RI "Note that for zero-terminated C strings, you should set " subject_length " to"
+.BI strlen( subject ) \fR,
+so that the dollar metacharacter matches at the end of the string, not after
+the string-terminating null byte. For convenience, an extra null byte is
+appended to the result so it can again be used as a string.
+
+.RI "The " subject " itself is left untouched, and the " *result " is dynamically"
+.RB "allocated, so it is the caller's responsibility to " free() " it when it's"
+no longer needed.
+
+.RI "The result's length (excluding the extra null byte) is written to " *result_length "."
+
+.RB "If the job matched, the " PCRS_SUCCESS " flag in"
+.IB job ->flags
+is set.
+
+
+.SS String subjects
+If your
+
+.SS Return value and diagnostics
+
+.RB "On success, " pcrs_execute() " returns the number of substitutions that"
+were made, which is limited to 0 or 1 for non-global searches.
+.RI "On failure, a negative error code is returned and " result " is set"
+.RB "to " NULL .
+
+.SH FREEING JOBS
+.RB "It is not sufficient to call " free() " on a " pcrs_job ", because it "
+contains pointers to other dynamically allocated structures.
+.RB "Use " pcrs_free_job() " instead. It is safe to pass " NULL " pointers "
+.RB "(or pointers to invalid " pcrs_job "s that contain " NULL " pointers"
+.RB "to dependant structures) to " pcrs_free_job() "."
+
+.SS Return value
+.RB "The value of the job's " next " pointer."
+
+
+.SH CHAINING JOBS
+
+.SM PCRS
+.RB "supports to some extent the chaining of multiple " pcrs_job " structures by"
+.RB "means of their " next " member."
+
+Chaining the jobs is up to you, but once you have built a linked list of jobs,
+.RI "you can execute a whole " joblist " on a given subject by"
+.RB "a single call to " pcrs_execute_list() ", which will sequentially traverse"
+.RB "the linked list until it reaches a " NULL " pointer, and call " pcrs_execute()
+.RI "for each job it encounters, feeding the " result " and " result_length " of each"
+.RI "call into the next as the " subject " and " subject_length ". As in the single"
+.RI "job case, the original " subject " remains untouched, but all interim " result "s"
+.RB "are of course " free() "d. The return value is the accumulated number of matches"
+.RI "for all jobs in the " joblist "."
+.RI "Note that while this is handy, it reduces the diagnostic value of " err ", since "
+you won't know which job failed.
+
+.RI "In analogy, you can free all jobs in a given " joblist " by calling"
+.BR pcrs_free_joblist() .
+
+.SH QUOTING
+The quote character is (surprise!) '\fB\\\fR'. It quotes the delimiter in a
+.IR command ", the"
+.RB ' $ "' in a"
+.IR substitute ", and, of course, itself. Note that the"
+.RB ' $ "' doesn't need to be quoted if it isn't followed by " [0-9+'`&] "."
+
+.RI "For quoting in the " pattern ", please refer to"
+.BR PCRE(3) .
+
+.SH DIAGNOSTICS
+
+.RB "When " compiling " a job either via the " pcrs_compile() " or " pcrs_compile_command()
+.RB "functions, you know that something went wrong when you are returned a " NULL " pointer."
+.RI "In that case, or in the event of non-fatal warnings, the integer pointed to by " err
+contains a nonzero error code, which is either a passed-through
+.SM PCRE
+error code or one generated by
+.SM PCRS.
+Under normal circumstances, it can take the following values:
+.TP
+.B PCRE_ERROR_NOMEMORY
+While compiling the pattern,
+.SM PCRE
+ran out of memory.
+.TP
+.B PCRS_ERR_NOMEM
+While compiling the job,
+.SM PCRS
+ran out of memory.
+.TP
+.B PCRS_ERR_CMDSYNTAX
+.BR pcrs_compile_command() " didn't find four tokens while parsing the"
+.IR command .
+.TP
+.B PCRS_ERR_STUDY
+A
+.SM PCRE
+.RB "error occured while studying the compiled pattern. Since " pcre_study()
+only provides textual diagnostic information, the details are lost.
+.TP
+.B PCRS_WARN_BADREF
+.RI "The " substitute " contains a reference to a capturing subpattern that"
+.RI "has a higher index than the number of capturing subpatterns in the " pattern
+or that exceeds the current hard limit of 33 (See LIMITATIONS below). As in Perl,
+this is non-fatal and results in substitutions with the empty string.
+
+.PP
+.RB "When " executing " jobs via " pcrs_execute() " or " pcrs_execute_list() ","
+.RI "a negative return code indicates an error. In that case, *" result
+.RB "is " NULL ". Possible error codes are:"
+.TP
+.B PCRE_ERROR_NOMEMORY
+While matching the pattern,
+.SM PCRE
+ran out of memory. This can only happen if there are more than 33 backrefrences
+.RI "in the " pattern "(!)"
+.BR and " memory is too tight to extend storage for more."
+.TP
+.B PCRS_ERR_NOMEM
+While executing the job,
+.SM PCRS
+ran out of memory.
+.TP
+.B PCRS_ERR_BADJOB
+.RB "The " pcrs_job "* passed to " pcrs_execute " was NULL, or the"
+.RB "job is bogus (it contains " NULL " pointers to the compiled
+pattern, extra, or substitute).
+
+.PP
+If you see any other
+.SM PCRE
+error code passed through, you've either messed with the compiled job
+or found a bug in
+.SM PCRS.
+Please send me an email.
+
+.RB "Ah, and don't look for " PCRE_ERROR_NOMATCH ", since this"
+is not an error in the context of
+.SM PCRS.
+.RI "Should there be no match, an exact copy of the " subject " is"
+.RI "found at *" result " and the return code is 0 (matches)."
+
+All error codes can be translated into human readable text by means
+.RB "of the " pcrs_strerror() " function."
+
+
+.SH EXAMPLE
+A trivial command-line test program for
+.SM PCRS
+might look like:
+
+.nf
+#include <pcrs.h>
+#include <stdio.h>
+
+int main(int Argc, char **Argv)
+{
+ pcrs_job *job;
+ char *result;
+ size_t newsize;
+ int err;
+
+ if (Argc != 3)
+ {
+ fprintf(stderr, "Usage: %s s/pattern/substitute/[options] subject\\n", Argv[0]);
+ return 1;
+ }
+
+ if (NULL == (job = pcrs_compile_command(Argv[1], &err)))
+ {
+ fprintf(stderr, "%s: compile error: %s (%d).\\n", Argv[0], pcrs_strerror(err), err);
+ }
+
+ if (0 > (err = pcrs_execute(job, Argv[2], strlen(Argv[2]), &result, &newsize)))
+ {
+ fprintf(stderr, "%s: exec error: %s (%d).\\n", Argv[0], pcrs_strerror(err), err);
+ }
+ else
+ {
+ printf("Result: *%s*\\n", result);
+ free(result);
+ }
+
+ pcrs_free_job(job);
+ return(err < 0);
+
+}
+
+.fi
+
+
+.SH LIMITATIONS
+The number of matches that a global job can have is only limited by the
+available memory. An initial storage for 40 matches is reserved, which
+is dynamically resized by the factor 1.6 whenever it is exhausted.
+
+The number of capturing subpatterns is currently limited to 33, which
+is a Bad Thing[tm]. It should be dynamically expanded until it reaches the
+.SM PCRE
+limit of 99.
+.br
+This limitation is particularly embarassing since
+.SM PCRE
+3.5 has raised the capturing subpattern limit to 65K.
+
+All of the above values can be adjusted in the "Capacity" section
+.RB "of " pcrs.h "."
+
+The Perl-style escape sequences for special characters \\\fInnn\fR,
+\\x\fInn\fR, and \\c\fIX\fR are currently unsupported.
+
+.SH BUGS
+This library has only been tested in the context of one application
+and should be considered high risk.
+
+.SH HISTORY
+.SM PCRS
+was originally written for the Privoxy project
+(http://www.privoxy.org/).

+ <ulink
+ url="http://www.gnu.org/software/make/make.html">GNU make

+</para>

+ When building from a source tarball,
+<!--
+ no longer available ...
+ <ulink
+ url="http://cvs.sourceforge.net/cvstarballs/ijbswa-cvsroot.tar.gz">nightly CVS
+ tarball</ulink>),
+--> first unpack the source:
+</para>
+
+<para>
+ <screen>
+ tar xzvf privoxy-&p-version;<![%p-not-stable;[-beta]]><![%p-stable;[-stable]]>-src.tar.gz
+ cd privoxy-&p-version;<![%p-not-stable;[-beta]]><![%p-stable;[-stable]]>
+</screen>
+</para>
+
+<para>
+ For retrieving the current CVS sources, you'll need a CVS client installed.
+ Note that sources from CVS are typically development quality, and may not be
+ stable, or well tested. To download CVS source, check the Sourceforge
+ documentation, which might give commands like:
+</para>
+
+<para>
+ <screen>
+ cvs -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa login
+ cvs -z3 -d:pserver:anonymous@ijbswa.cvs.sourceforge.net:/cvsroot/ijbswa co current
+ cd current
+</screen>
+</para>
+
+<para>
+ This will create a directory named <filename>current/</filename>, which will
+ contain the source tree.
+</para>
+
+<para>
+ You can also check out any <application>Privoxy</application>
+ <quote>branch</quote>, just exchange the <application>current</application>
+ name with the wanted branch name (Example: v_3_0_branch for the 3.0 cvs
+ tree).
+</para>
+
+<para>
+ It is also strongly recommended to not run <application>Privoxy</application>
+ as root. You should configure/install/run <application>Privoxy</application> as
+ an unprivileged user, preferably by creating a <quote>privoxy</quote> user
+ and group just for this purpose. See your local documentation for the correct
+ command line to do add new users and groups (something like
+ <command>adduser</command>, but the command syntax may vary from platform
+ to platform).
+</para>
+
+<para>
+ <filename>/etc/passwd</filename> might then look like:
+</para>
+
+<para>
+ <screen> privoxy:*:7777:7777:privoxy proxy:/no/home:/no/shell</screen>
+</para>
+
+<para>
+ And then <filename>/etc/group</filename>, like:
+</para>
+
+<para>
+ <screen> privoxy:*:7777:</screen>
+</para>
+
+<para>
+ Some binary packages may do this for you.
+</para>
+
+<para>
+ Then, to build from either unpacked tarball or CVS source:
+</para>
+
+<para>
+ <screen>
+ autoheader
+ autoconf
+ ./configure # (--help to see options)
+ make # (the make from GNU, sometimes called gmake)
+ su # Possibly required
+ make -n install # (to see where all the files will go)
+ make -s install # (to really install, -s to silence output)</screen>
+</para>
+
+<para>
+ Using GNU <command>make</command>, you can have the first four steps
+ automatically done for you by just typing:
+</para>
+
+<para>
+ <screen>
+ make
+</screen>
+</para>
+
+<para>
+ in the freshly downloaded or unpacked source directory.
+</para>
+
+<para>
+ To build an executable with security enhanced features so that
+ users cannot easily bypass the proxy (e.g. <quote>Go There Anyway</quote>), or
+ alter their own configurations, <command>configure</command> like this:
+</para>
+<para>
+ <screen>
+ ./configure --disable-toggle --disable-editor --disable-force</screen>
+</para>
+<para>
+Then build as above. In Privoxy 3.0.7 and later, all of these options
+can also be disabled through the configuration file.
+</para>
+<para>
+ <emphasis>WARNING:</emphasis> If installing as root, the install will fail
+ unless a non-root user or group is specified, or a <literal>privoxy</literal>
+ user and group already exist on the system. If a non-root user is specified,
+ and no group, then the installation will try to also use a group of the same name
+ as <quote>user</quote>. If a group is specified (and no user), then the
+ support files will be installed as writable by that group, and owned by the
+ user running the installation.
+</para>
+
+<para>
+ <command>configure</command> accepts <literal>--with-user</literal> and
+ <literal>--with-group</literal> options for setting user and group ownership
+ of the configuration files (which need to be writable by the daemon). The
+ specified <emphasis>user must already exist</emphasis>. When starting
+ <application>Privoxy</application>, it must be run as this same user to
+ insure write access to configuration and log files!
+</para>
+
+<para>
+ Alternately, you can specify <literal>user</literal> and <literal>group</literal>
+ on the <command>make</command> command line, but be sure both already exist:
+</para>
+
+<para>
+ <screen>
+ make -s install USER=privoxy GROUP=privoxy</screen>
+</para>
+
+<para>
+ The default installation path for <command>make install</command> is
+ <filename>/usr/local</filename>. This may of course be customized with
+ the various <command>./configure</command> path options. If you are doing
+ an install to anywhere besides <filename>/usr/local</filename>, be
+ sure to set the appropriate paths with the correct configure options
+ (<command>./configure --help</command>). Non-privileged users must of course
+ have write access permissions to wherever the target installation is going.
+</para>
+
+<para>
+ If you do install to <filename>/usr/local</filename>, the install will use
+ <literal>sysconfdir=$prefix/etc/privoxy</literal> by default. All other
+ destinations, and the direct usage of <literal>--sysconfdir</literal> flag
+ behave like normal, i.e. will not add the extra <filename>privoxy</filename>
+ directory. This is for a safer install, as there may already exist another
+ program that uses a file with the <quote>config</quote> name, and thus makes
+ <filename>/usr/local/etc</filename> cleaner.
+</para>
+
+<para>
+ If installing to <filename>/usr/local</filename>, the documentation will go
+ by default to <filename>$prefix/share/doc</filename>. But if this directory
+ doesn't exist, it will then try <filename>$prefix/doc</filename> and install
+ there before creating a new <filename>$prefix/share/doc</filename> just for
+ <application>Privoxy</application>.
+</para>
+
+<para>
+ Again, if the installs goes to <filename>/usr/local</filename>, the
+ <literal>localstatedir</literal> (ie: <filename>var/</filename>) will default
+ to <filename>/var</filename> instead of <literal>$prefix/var</literal> so
+ the logs will go to <filename>/var/log/privoxy/</filename>, and the pid file
+ will be created in <filename>/var/run/privoxy.pid</filename>.
+</para>
+
+<para>
+ <command>make install</command> will attempt to set the correct values
+ in <filename>config</filename> (main configuration file). You should
+ check this to make sure all values are correct. If appropriate,
+ an init script will be installed, but it is up to the user to determine
+ how and where to start <application>Privoxy</application>. The init
+ script should be checked for correct paths and values, if anything other than
+ a default install is done.
+</para>
+
+<para>
+ If install finds previous versions of local configuration files, most of
+ these will not be overwritten, and the new ones will be installed with a
+ <quote>new</quote> extension. default.action and default.filter
+ <emphasis>will be overwritten</emphasis>. You will then need
+ to manually update the other installed configuration files as needed. The
+ default template files <emphasis>will</emphasis> be overwritten. If you have
+ customized, local templates, these should be stored safely in a separate
+ directory and defined in <filename>config</filename> by the
+ <quote>templdir</quote> directive. It is of course wise to always back-up any
+ important configuration files <quote>just in case</quote>. If a previous
+ version of <application>Privoxy</application> is already running, you will
+ have to restart it manually.
+</para>

+ The project's CVS repository is hosted on
+ <ulink url="http://sourceforge.net/">SourceForge.</ulink>
+ Please refer to the chapters 6 and 7 in
+ <ulink url="http://sourceforge.net/docman/?group_id=1">SF's site
+ documentation</ulink> for the technical access details for your
+ operating system. For historical reasons, the CVS server is
+ called <literal>ijbswa.cvs.sourceforge.net</literal>, the repository is

+ <literal>current</literal>.

+ <title>Branches</title>
+ <para>
+ Within the CVS repository, there are modules and branches. As
+ mentioned, the sources are in the <literal>current</literal>
+ <quote>module</quote>. Other modules are present for platform specific
+ issues. There is a webview of the CVS hierarchy at <ulink
+ url="http://ijbswa.cvs.sourceforge.net/ijbswa/">http://ijbswa.cvs.sourceforge.net/ijbswa/</ulink>,
+ which might help with visualizing how these pieces fit together.
+ </para>
+ <para>
+ Branches are used to fork a sub-development path from the main trunk.
+ Within the <literal>current</literal> module where the sources are, there
+ is always at least one <quote>branch</quote> from the main trunk
+ devoted to a stable release series. The main trunk is where active
+ development takes place for the next stable series (e.g. 3.2.x).
+ So just prior to each stable series (e.g. 3.0.x), a branch is created
+ just for stable series releases (e.g. 3.0.0 -> 3.0.1 -> 3.0.2, etc).
+ Once the initial stable release of any stable branch has taken place,
+ this branch is <emphasis>only used for bugfixes</emphasis>, which have
+ had prior testing before being committed to CVS. (See <link
+ linkend="versionnumbers">Version Numbers</link> below for details on
+ versioning.)
+ </para>
+ <para>
+ At one time there were two distinct branches: stable and unstable. The
+ more drastic changes were to be in the unstable branch. These branches
+ have now been merged to minimize time and effort of maintaining two
+ branches.
+ </para>
+ <!--
+ <para>
+ This will result in at least two active branches, which means there may
+ be occasions that require the same (or similar) item to be
+ checked into to two different places (assuming its a bugfix and needs
+ fixing in both the stable and unstable trees). This also means that in
+ order to have access to both trees, both will have to be checked out
+ separately. Use the <literal>cvs -r</literal> flag to check out a
+ branch, e.g: <literal>cvs co -r v_3_0_branch current</literal>.

+ The source tree is the heart of every software project. Every effort must

+ DTD's and the Docbook modular stylesheets (or comparable alternatives),
+ and either <application>jade</application> or
+ <application>openjade</application> (recommended) installed in order to

+ <ulink url="../faq/index.html"><citetitle>FAQ</citetitle></ulink>, and, of
+ course this, the <citetitle>developer-manual</citetitle> in this format.
+ The <citetitle>README</citetitle>, <citetitle>AUTHORS</citetitle>,
+ <citetitle>INSTALL</citetitle>,
+ <citetitle>privoxy.1</citetitle> (man page), and
+ <citetitle>config</citetitle> files are also now maintained as Docbook
+ SGML. These files, when built, in the top-level source directory are
+ generated files! Also, the <application>Privoxy</application> <filename>index.html</filename> (and a
+ variation on this file, <filename>privoxy-index.html</filename>,
+ meant for inclusion with doc packages), are maintained as SGML as well.
+ <emphasis>DO NOT edit these directly</emphasis>. Edit the SGML source, or

+ <para>
+ <filename>config</filename> requires some special handling. The reason it
+ is maintained this way is so that the extensive comments in the file
+ mirror those in <citetitle>user-manual</citetitle>. But the conversion
+ process requires going from SGML to HTML to text to special formatting
+ required for the embedded comments. Some of this does not survive so
+ well. Especially some of the examples that are longer than 80 characters.
+ The build process for this file outputs to <filename>config.new</filename>,
+ which should be reviewed for errors and mis-formatting. Once satisfied

+<title>Quickstart to Docbook and SGML</title>
+<para>
+ If you are not familiar with SGML, it is a markup language similar to HTML.
+ Actually, not a mark up language per se, but a language used to define
+ markup languages. In fact, HTML is an SGML application. Both will use
+ <quote>tags</quote> to format text and other content. SGML tags can be much
+ more varied, and flexible, but do much of the same kinds of things. The tags,
+ or <quote>elements</quote>, are definable in SGML. There is no set
+ <quote>standards</quote>. Since we are using
+ <application>Docbook</application>, our tags are those that are defined by
+ <application>Docbook</application>. Much of how the finish document is
+ rendered is determined by the <quote>stylesheets</quote>.
+ The stylesheets determine how each tag gets translated to HTML, or other
+ formats.
+</para>
+
+<para>
+ Tags in Docbook SGML need to be always <quote>closed</quote>. If not, you
+ will likely generate errors. Example: <literal><title>My
+ Title</title></literal>. They are also case-insensitive, but we
+ strongly suggest using all lower case. This keeps compatibility with
+ [Docbook] <application>XML</application>.
+</para>
+
+<para>
+ Our documents use <quote>sections</quote> for the most part. Sections
+ will be processed into HTML headers (e.g. <literal>h1</literal> for
+ <literal>sect1</literal>). The <application>Docbook</application> stylesheets
+ will use these to also generate the Table of Contents for each doc. Our
+ TOC's are set to a depth of three. Meaning <literal>sect1</literal>,
+ <literal>sect2</literal>, and <literal>sect3</literal> will have TOC
+ entries, but <literal>sect4</literal> will not. Each section requires
+ a <literal><title></literal> element, and at least one
+ <literal><para></literal>. There is a limit of five section
+ levels in Docbook, but generally three should be sufficient for our
+ purposes.

+ documentation maintenance.
+ </para>
+ <para>
+ We are using a set of <quote>boilerplate</quote> files with generic text,
+ that is used by multiple docs. This way we can write something once, and use
+ it repeatedly without having to re-write the same content over and over again.
+ If editing such a file, keep in mind that it should be
+ <emphasis>generic</emphasis>. That is the purpose; so it can be used in varying
+ contexts without additional modifications.
+ </para>
+ <para>
+ We are also using what <application>Docbook</application> calls
+ <quote>internal entities</quote>. These are like variables in
+ programming. Well, sort of. For instance, we have the
+ <literal>p-version</literal> entity that contains the current
+ <application>Privoxy</application> version string. You are strongly
+ encouraged to use these where possible. Some of these obviously
+ require re-setting with each release (done by the Makefile). A sampling of
+ custom entities are listed below. See any of the main docs for examples.

+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>Comment as much as possible without commenting the obvious.
+ For example do not comment "variable_a is equal to variable_b".
+ Instead explain why variable_a should be equal to the variable_b.
+ Just because a person can read code does not mean they will
+ understand why or what is being done. A reader may spend a lot
+ more time figuring out what is going on when a simple comment
+ or explanation would have prevented the extra research. Please
+ help your brother IJB'ers out!</para>
+
+ <para>The comments will also help justify the intent of the code.
+ If the comment describes something different than what the code
+ is doing then maybe a programming error is occurring.</para>
+
+ <para><emphasis>Example:</emphasis></para>
+<programlisting>
+/* if page size greater than 1k ... */
+if ( page_length() > 1024 )

+
+/* if page size is small, send it in blocks */

+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>Comments can help or they can clutter. They help when they

+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>A reader of the code should be able to look at the comments
+ just prior to the beginning of a function and discern the

+ function not only saves time for subsequent maintenance or

+ for the problem at hand. As a result of such benefits, all

+ <sect3 id="s8"><title>Comment at the end of braces if the

+ <para>It is easy to write the following code, and a clear argument
+ can be made that the code is easy to understand:</para>
+
+ <para><emphasis>Example:</emphasis></para>
+<programlisting>
+for ( size_t cnt = 0; cnt < block_list_length(); cnt++ )
+{
+ ....
+}</programlisting>
+
+ <para><emphasis>Note:</emphasis> Unfortunately, this makes a function call for
+ each and every iteration. This increases the overhead in the
+ program, because the compiler has to look up the function each
+ time, call it, and return a value. Depending on what occurs in
+ the block_list_length() call, it might even be creating and
+ destroying structures with each iteration, even though in each
+ case it is comparing "cnt" to the same value, over and over.
+ Remember too - even a call to block_list_length() is a function
+ call, with the same overhead.</para>
+
+ <para>Instead of using a function call during the iterations,
+ assign the value to a variable, and evaluate using the
+ variable.</para>
+
+ <para><emphasis>Example:</emphasis></para>
+<programlisting>
+size_t len = block_list_length();
+
+for ( size_t cnt = 0; cnt < len; cnt++ )
+{
+ ....
+}</programlisting>
+
+ <para><emphasis>Exceptions:</emphasis> if the value of block_list_length()
+ *may* change or could *potentially* change, then you must code the
+ function call in the for/while loop.</para>
+
+
+ </sect3>
+
+
+ <sect3 id="s29"><title>Pass and Return by Const Reference</title>
+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>This allows a developer to define a const pointer and call
+ your function. If your function does not have the const
+ keyword, we may not be able to use your function. Consider
+ strcmp, if it were defined as: extern int strcmp( char *s1,
+ char *s2 );</para>
+
+ <para>I could then not use it to compare argv's in main: int main(
+ int argc, const char *argv[] ) { strcmp( argv[0], "privoxy"
+ ); }</para>
+
+ <para>Both these pointers are *const*! If the c runtime library
+ maintainers do it, we should too.</para>
+
+
+ </sect3>
+
+
+ <sect3 id="s30"><title>Pass and Return by Value</title>
+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>Most structures cannot fit onto a normal stack entry (i.e.
+ they are not 4 bytes or less). Aka, a function declaration
+ like: int load_aclfile( struct client_state csp )</para>
+
+ <para>would not work. So, to be consistent, we should declare all
+ prototypes with "pass by value": int load_aclfile( struct
+ client_state *csp )</para>
+
+
+ </sect3>
+
+
+ <sect3 id="s31"><title>Names of include files</title>
+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>Your include statements should contain the file name without
+ a path. The path should be listed in the Makefile, using -I as
+ processor directive to search the indicated paths. An exception
+ to this would be for some proprietary software that utilizes a
+ partial path to distinguish their header files from system or
+ other header files.</para>
+
+ <para><emphasis>Example:</emphasis></para>
+<programlisting>
+#include <iostream.h> /* This is not a local include */
+#include "config.h" /* This IS a local include */
+</programlisting>
+
+ <para><emphasis>Exception:</emphasis></para>
+
+ <para>
+<programlisting>
+/* This is not a local include, but requires a path element. */
+#include <sys/fileName.h>
+</programlisting>
+</para>
+
+ <para><emphasis>Note:</emphasis> Please! do not add "-I." to the Makefile
+ without a _very_ good reason. This duplicates the #include
+ "file.h" behavior.</para>
+

+ </sect3>

+
+ <sect3 id="s32"><title>Provide multiple inclusion
+ protection</title>
+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>Prevents compiler and linker errors resulting from
+ redefinition of items.</para>
+
+ <para>Wrap each header file with the following syntax to prevent
+ multiple inclusions of the file. Of course, replace PROJECT_H
+ with your file name, with "." Changed to "_", and make it
+ uppercase.</para>
+
+ <para><emphasis>Example:</emphasis></para>
+<programlisting>
+#ifndef PROJECT_H_INCLUDED
+#define PROJECT_H_INCLUDED
+ ...
+#endif /* ndef PROJECT_H_INCLUDED */
+</programlisting>
+ </sect3>
+
+
+ <sect3 id="s33"><title>Use `extern "C"` when appropriate</title>
+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>If our headers are included from C++, they must declare our
+ functions as `extern "C"`. This has no cost in C, but increases
+ the potential re-usability of our code.</para>
+
+ <para><emphasis>Example:</emphasis></para>
+<programlisting>
+#ifdef __cplusplus
+extern "C"
+{
+#endif /* def __cplusplus */
+
+... function definitions here ...

+
+ <para><emphasis>Explanation:</emphasis></para>

+
+ <para>What you think is guaranteed is never really guaranteed. The
+ value that you don't think you need to check is the one that

+
+ <para><emphasis>Note:</emphasis> If you already have a default condition, you
+ are obviously exempt from this point. Of note, most of the
+ WIN32 code calls `DefWindowProc' after the switch statement.
+ This API call *should* be included in a default statement.</para>
+
+ <para><emphasis>Another Note:</emphasis> This is not so much a readability issue
+ as a robust programming issue. The "anomaly code goes here" may
+ be no more than a print to the STDERR stream (as in
+ load_config). Or it may really be an abort condition.</para>

+
+ <sect3 id="s38"><title>Try to avoid falling through cases in a

+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>In general, you will want to have a 'break' statement within
+ each 'case' of a switch statement. This allows for the code to
+ be more readable and understandable, and furthermore can
+ prevent unwanted surprises if someone else later gets creative
+ and moves the code around.</para>
+
+ <para>The language allows you to plan the fall through from one
+ case statement to another simply by omitting the break
+ statement within the case statement. This feature does have
+ benefits, but should only be used in rare cases. In general,
+ use a break statement for each case statement.</para>
+
+ <para>If you choose to allow fall through, you should comment both
+ the fact of the fall through and reason why you felt it was
+ necessary.</para>

+
+
+ <sect3 id="s39"><title>Use 'long' or 'short' Instead of

+
+ <para><emphasis>Explanation:</emphasis></para>
+
+ <para>On 32-bit platforms, int usually has the range of long. On
+ 16-bit platforms, int has the range of short.</para>
+
+ <para><emphasis>Status:</emphasis> open-to-debate. In the case of most FSF

+ <para>
+ When we release versions of <application>Privoxy</application>,
+ our work leaves our cozy secret lab and has to work in the cold
+ RealWorld[tm]. Once it is released, there is no way to call it
+ back, so it is very important that great care is taken to ensure
+ that everything runs fine, and not to introduce problems in the
+ very last minute.
+ </para>
+ <para>
+ So when releasing a new version, please adhere exactly to the
+ procedure outlined in this chapter.
+ </para>
+
+ <para>
+ The following programs are required to follow this process:
+ <filename>ncftpput</filename> (ncftp), <filename>scp, ssh</filename> (ssh),
+ <filename>gmake</filename> (GNU's version of make), autoconf, cvs.
+ </para>
+
+ <sect2 id="versionnumbers">
+ <title>Version numbers</title>
+
+ <para>
+ First you need to determine which version number the release will have.
+ <application>Privoxy</application> version numbers consist of three numbers,
+ separated by dots, like in X.Y.Z (e.g. 3.0.0), where:
+ <itemizedlist>
+ <listitem>
+ <para>
+ X, the version major, is rarely ever changed. It is increased by one if
+ turning a development branch into stable substantially changes the functionality,
+ user interface or configuration syntax. Majors 1 and 2 were
+ <application>Junkbuster</application>, and 3 will be the first stable
+ <application>Privoxy</application> release.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Y, the version minor, represents the branch within the major version.
+ At any point in time, there are two branches being maintained:
+ The stable branch, with an even minor, say, 2N, in which no functionality is
+ being added and only bug-fixes are made, and 2N+1, the development branch, in
+ which the further development of <application>Privoxy</application> takes
+ place.
+ This enables us to turn the code upside down and inside out, while at the same time
+ providing and maintaining a stable version.
+ The minor is reset to zero (and one) when the major is incremented. When a development
+ branch has matured to the point where it can be turned into stable, the old stable branch
+ 2N is given up (i.e. no longer maintained), the former development branch 2N+1 becomes the
+ new stable branch 2N+2, and a new development branch 2N+3 is opened.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Z, the point or sub version, represents a release of the software within a branch.
+ It is therefore incremented immediately before each code freeze.
+ In development branches, only the even point versions correspond to actual releases,
+ while the odd ones denote the evolving state of the sources on CVS in between.
+ It follows that Z is odd on CVS in development branches most of the time. There, it gets
+ increased to an even number immediately before a code freeze, and is increased to an odd
+ number again immediately thereafter.
+ This ensures that builds from CVS snapshots are easily distinguished from released versions.
+ The point version is reset to zero when the minor changes.
+ </para>
+ <para>
+ Stable branches work a little differently, since there should be
+ little to no development happening in such branches. Remember,
+ only bugfixes, which presumably should have had some testing
+ before being committed. Stable branches will then have their
+ version reported as <literal>0.0.0</literal>, during that period
+ between releases when changes are being added. This is to denote
+ that this code is <emphasis>not for release</emphasis>. Then
+ as the release nears, the version is bumped according: e.g.
+ <literal>3.0.1 -> 0.0.0 -> 3.0.2</literal>.
+ </para>
+ </listitem>
+ </itemizedlist>
+ </para>
+ <para>
+ In summary, the main CVS trunk is the development branch where new
+ features are being worked on for the next stable series. This should
+ almost always be where the most activity takes place. There is always at
+ least one stable branch from the trunk, e.g now it is
+ <literal>3.0</literal>, which is only used to release stable versions.
+ Once the initial *.0 release of the stable branch has been done, then as a
+ rule, only bugfixes that have had prior testing should be committed to
+ the stable branch. Once there are enough bugfixes to justify a new
+ release, the version of this branch is again incremented Example: 3.0.0
+ -> 3.0.1 -> 3.0.2, etc are all stable releases from within the stable
+ branch. 3.1.x is currently the main trunk, and where work on 3.2.x is
+ taking place. If any questions, please post to the devel list
+ <emphasis>before</emphasis> committing to a stable branch!

+ <sect1 id="webserver-update"><title>Update the Webserver</title>
+ <para>
+ The webserver should be updated at least with each stable release. When
+ updating, please follow these steps to make sure that no broken links,
+ inconsistent contents or permission problems will occur (as it has many
+ times in the past!):
+ </para>
+ <para>
+ If you have changed anything in the stable-branch documentation source
+ SGML files, do:
+ </para>
+ <para>
+ <programlisting>
+ make dok dok-pdf # (or 'make redhat-dok dok-pdf' if 'make dok' doesn't work for you)
+</programlisting>
+ </para>
+ <para>
+ That will generate <filename>doc/webserver/user-manual</filename>,
+ <filename>doc/webserver/developer-manual</filename>,
+ <filename>doc/webserver/faq</filename>,
+ <filename>doc/pdf/*.pdf</filename> and
+ <filename>doc/webserver/index.html</filename> automatically.
+ </para>
+ <para>
+ If you changed the manual page sources, generate
+ <filename>doc/webserver/man-page/privoxy-man-page.html</filename>
+ by running <quote><command>make man</command></quote>. (This is
+ a separate target due to dependencies on some obscure perl scripts
+ [now in CVS, but not well tested]. See comments in <filename>GNUmakefile</filename>.)
+ </para>
+ <para>
+ If you want to add new files to the webserver, create them locally in
+ the <filename>doc/webserver/*</filename> directory (or
+ create new directories under <filename>doc/webserver</filename>).
+ </para>
+ <para>
+ Next, commit any changes from the above steps to CVS. All set?
+ If these are docs in the stable branch, then do:
+ </para>
+ <para>
+ <programlisting>
+ make webserver
+</programlisting>
+ </para>
+ <para>
+ This will do the upload to <ulink url="http://www.privoxy.org/">the
+ webserver</ulink> (www.privoxy.org) and ensure all files and directories
+ there are group writable.
+ </para>
+ <para>
+ Please do <emphasis>NOT</emphasis> use any other means of transferring
+ files to the webserver to avoid permission problems. Also, please do not
+ upload docs from development branches or versions. The publicly posted
+ docs should be in sync with the last official release.

+ (i.e. browsers) can use instead of connecting to web servers directly.
+ The clients then ask the proxy to request objects (web pages, images, movies etc)
+ on their behalf and to forward the data to the clients.
+ It is a <quote>go-between</quote>. For details, see
+ <ulink url="http://en.wikipedia.org/wiki/Proxy_server">Wikipedia's proxy definition</ulink>.

+ &my-app; is a proxy that is primarily focused on

+<para>
+ <application>Privoxy</application>'s approach to blocking ads is twofold:
+</para>
+<para>
+ First, there are certain patterns in the <emphasis>locations</emphasis> (URLs)
+ of banner images. This applies to both the path (you wouldn't guess how many
+ web sites serve their banners from a directory called <quote>banners</quote>!)
+ and the host (blocking the big banner hosting services like doublecklick.net
+ already helps a lot). <application>Privoxy</application> takes advantage of this
+ fact by using <ulink url="../user-manual/actions-file.html#AF-PATTERNS">URL
+ patterns</ulink> to sort out and block the requests for things that sound
+ like they would be ads or banners.
+</para>
+<para>
+ Second, banners tend to come in certain <emphasis>sizes</emphasis>. But you
+ can't tell the size of an image by its URL without downloading it, and if you
+ do, it's too late to save bandwidth. Therefore, <application>Privoxy</application>
+ also inspects the HTML sources of web pages while they are loaded, and replaces
+ references to images with standard banner sizes by dummy references, so that
+ your browser doesn't request them anymore in the first place.
+</para>
+<para>
+ Both of this involves a certain amount of guesswork and is, of course, freely
+ and readily configurable.

+</sect2>

+<sect2 renderas="sect3">
+<title id="mistakes">Can Privoxy make mistakes?

+ Actually, it's a black art ;-) And yes, it is always possible to have a broad

+ <application>Privoxy</application>. If there is a match for a <literal><ulink

+ <para>
+ Filtering is potentially more of a concern since the results are not always
+ so obvious, and the effects of filtering are there whether the file is simply
+ viewed, or downloaded. And potentially whether the content is some obnoxious
+ advertisement, or Mr. Jimmy's latest/greatest source code jewel. Of course,
+ one of these presumably is <quote>bad</quote> content that we don't want, and
+ the other is <quote>good</quote> content that we do want.
+ <application>Privoxy</application> is blind to the differences, and can only
+ distinguish <quote>good from bad</quote> by the configuration parameters
+ <emphasis>we</emphasis> give it.
+</para>
+<para>
+ <application>Privoxy</application> knows the differences in files according
+ to the <quote>Content Type</quote> as reported by the webserver. If this is
+ reported accurately (e.g. <quote>application/zip</quote> for a zip archive),
+ then <application>Privoxy</application> knows to ignore these where
+ appropriate. <application>Privoxy</application> potentially can filter HTML
+ as well as plain text documents, subject to configuration parameters of
+ course. Also, documents that are of an unknown type (generally assumed to be
+ <quote>text/plain</quote>) can be filtered, as will those that might be
+ incorrectly reported by the webserver. If such a file is a downloaded file
+ that is intended to be saved to disk, then any content that might have been
+ altered by filtering, will be saved too, for these (probably rare) cases.

+ In short, filtering is <quote>ON</quote> if a) the content type as reported

+ If you download text files, you probably do not want these to be filtered,

+ The reason for this is that each user's set-up for IE is user specific. Each

+ A long time ago, there was the
+ <ulink url="http://www.junkbusters.com/ijb.html"><application>Internet Junkbuster</application></ulink>,
+ by Anonymous Coders and <ulink url="http://www.junkbusters.com/">Junkbusters
+ Corporation</ulink>. This saved many users a lot of pain in the early days of
+ web advertising and user tracking.
+</para>
+
+<para>
+ But the web, its protocols and standards, and with it, the techniques for
+ forcing ads on users, give up autonomy over their browsing, and
+ for tracking them, keeps evolving. Unfortunately, the <application>Internet
+ Junkbuster</application> did not. Version 2.0.2, published in 1998, was
+ (and is) the last official
+ <ulink url="http://www.junkbusters.com/ijbdist.html#release">release</ulink>
+ available from <ulink url="http://www.junkbusters.com">Junkbusters Corporation</ulink>.
+ Fortunately, it had been released under the GNU
+ <ulink url="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html">GPL</ulink>,
+ which allowed further development by others.
+</para>
+
+<para>
+ So Stefan Waldherr started maintaining an improved version of the
+ software, to which eventually a number of people contributed patches.
+ It could already replace banners with a transparent image, and had a first
+ version of pop-up killing, but it was still very closely based on the
+ original, with all its limitations, such as the lack of HTTP/1.1 support,
+ flexible per-site configuration, or content modification. The last release
+ from this effort was version 2.0.2-10, published in 2000.
+</para>
+
+<para>
+ Then, some
+ <ulink url="http://www.privoxy.org/user-manual/copyright.html#AUTHORS">developers</ulink>
+ picked up the thread, and started turning the software inside out, upside down,
+ and then reassembled it, adding many
+ <ulink url="http://www.privoxy.org/user-manual/introduction.html#FEATURES">new
+ features</ulink> along the way.
+</para>
+
+<para>
+ The result of this is <application>Privoxy</application>, whose first
+ stable version, 3.0, was released August, 2002.

+ This file contains all the config file comments and options. It used to
+ build both the user-manual config sections, and all of config (yes, the main
+ config file) itself.
+
+ Rationale: This is broken up into two files since a file with a prolog
+ (DTD, etc) cannot be sourced as a secondary file. config.sgml is basically
+ a wrapper for this file.
+
+ IMPORTANT:
+
+ OPTIONS: The actual options are included in this file and prefixed with
+ '@@', and processed by the Makefile to strip the '@@'. Default options
+ that should appear commented out should be listed as: '@@#OPTION'.
+ Otherwise, as '@@OPTION'. Example:
+
+ @@listen-address 127.0.0.1:8118
+
+ The Makefile does significant other processing too. The final results
+ should be checked to make sure that the perl processing does not
+ fubar something!!! Makefile processing requires w3m, fmt (shell line
+ formatter), and perl.
+
+
+ This file is included into:
+
+ user-manual.sgml

+ Again, the main configuration file is named <filename>config</filename> on

+<literallayout>I. INTRODUCTION
+ =============== <!-- fuck this madness --></literallayout>
+
+<para>
+ This file holds Privoxy's main configuration. Privoxy detects
+ configuration changes automatically, so you don't have to restart it
+ unless you want to load a different configuration file.
+</para>
+<para>
+ The configuration will be reloaded with the first request after the
+ change was done, this request itself will still use the old configuration,
+ though. In other words: it takes two requests before you see the result of
+ your changes. Requests that are dropped due to ACL don't trigger reloads.
+</para>
+<para>
+ When starting Privoxy on Unix systems, give the location of this
+ file as last argument. On Windows systems, Privoxy will look for
+ this file with the name 'config.txt' in the current working directory
+ of the Privoxy process.
+</para>
+
+<para>
+ <literallayout><!-- funky spacing -->
+
+II. FORMAT OF THE CONFIGURATION FILE
+====================================</literallayout>
+</para>
+<para>
+ Configuration lines consist of an initial keyword followed by a list
+ of values, all separated by whitespace (any number of spaces or
+ tabs). For example,
+</para>
+<para>
+ actionsfile default.action
+</para>
+<para>
+ Indicates that the actionsfile is named 'default.action'.
+</para>
+<para>
+ The '#' indicates a comment. Any part of a line following a '#' is
+ ignored, except if the '#' is preceded by a '\'.
+</para>
+<para>
+ Thus, by placing a # at the start of an existing configuration line,
+ you can make it a comment and it will be treated as if it weren't there.
+ This is called "commenting out" an option and can be useful. Removing
+ the # again is called "uncommenting".
+</para>
+<para>
+ Note that commenting out an option and leaving it at its default
+ are two completely different things! Most options behave very
+ differently when unset. See the "Effect if unset" explanation
+ in each option's description for details.
+</para>
+<para>
+ Long lines can be continued on the next line by using a `\' as
+ the last character.
+</para>

+ </para>

+ If you specify a trust file, <application>Privoxy</application> will only allow

+ in one of two ways:
+ </para>
+ <para>
+ Prepending a <literal>~</literal> character limits access to this site
+ only (and any sub-paths within this site), e.g.
+ <literal>~www.example.com</literal> allows access to
+ <literal>~www.example.com/features/news.html</literal>, etc.
+ </para>
+ <para>
+ Or, you can designate sites as <emphasis>trusted referrers</emphasis>, by
+ prepending the name with a <literal>+</literal> character. The effect is that
+ access to untrusted sites will be granted -- but only if a link from this
+ trusted referrer was used to get there. The link target will then be added
+ to the <quote>trustfile</quote> so that future, direct accesses will be
+ granted. Sites added via this mechanism do not become trusted referrers
+ themselves (i.e. they are added with a <literal>~</literal> designation).
+ There is a limit of 512 such entries, after which new entries will not be
+ made.
+ </para>
+ <para>
+ If you use the <literal>+</literal> operator in the trust file, it may grow
+ considerably over time.

+ <screen>
+ # Define Privoxy as parent proxy (without ICP)

+ always_direct allow ftp
+
+ # Forward all the rest to Privoxy
+ never_direct allow all</screen>
+</para>
+
+<para>
+ You would then need to change your browser's proxy settings to <application>squid</application>'s address and port.
+ Squid normally uses port 3128. If unsure consult <literal>http_port</literal> in <filename>squid.conf</filename>.
+</para>

+<para>
+ Browsers can either be individually configured to use
+ <command>Privoxy</command> as a HTTP proxy (recommended),
+ or <command>Privoxy</command> can be combined with a packet
+ filter to build an intercepting proxy
+ (see <filename>config</filename>). The default setting is for
+ localhost, on port 8118 (configurable in the main config file). To set the
+ HTTP proxy in Firefox, go through: <command>Tools</command>;
+ <command>Options</command>; <command>General</command>;
+ <command>Connection Settings</command>;
+ <command>Manual Proxy Configuration</command>.
+</para>
+<para>
+ For Internet Explorer, go through: <command>Tools</command>;
+ <command>Internet Properties</command>; <command>Connections</command>;
+ <command>LAN Settings</command>.
+</para>
+<para>
+ The Secure (SSL) Proxy should also be set to the same values, otherwise
+ https: URLs will not be proxied. Note: <command>Privoxy</command> can only
+ proxy HTTP and HTTPS traffic. Do not try it with FTP or other protocols.
+ HTTPS presents some limitations, and not all features will work with HTTPS
+ connections.
+</para>
+
+<para>
+ For other browsers, check the documentation.

+
+
+<!-- ~~~~~ New section ~~~~~ -->
+<refsect1><title>Configuration</title>
+<para>
+ <command>Privoxy</command> can be configured with the various configuration
+ files. The default configuration files are: <filename>config</filename>,
+ <filename>default.filter</filename>, <filename>default.action</filename> and
+ <filename>default.action</filename>. <filename>user.action</filename> should
+ be used for locally defined exceptions to the default rules in
+ <filename>match-all.action</filename> and <filename>default.action</filename>,
+ and <filename>user.filter</filename> for locally defined filters. These are
+ well commented. On Unix and Unix-like systems, these are located in
+ <filename>/etc/privoxy/</filename> by default.
+</para>
+<para>
+ <command>Privoxy</command> uses the concept of <command>actions</command>
+ in order to manipulate the data stream between the browser and remote sites.
+ There are various actions available with specific functions for such things
+ as blocking web sites, managing cookies, etc. These actions can be invoked
+ individually or combined, and used against individual URLs, or groups of URLs
+ that can be defined using wildcards and regular expressions. The result is
+ that the user has greatly enhanced control and freedom.
+</para>
+<para>
+ The actions list (ad blocks, etc) can also be configured with your
+ web browser at <ulink url="http://config.privoxy.org/">http://config.privoxy.org/</ulink>
+ (assuming the configuration allows it).
+ <command>Privoxy's</command> configuration parameters can also be viewed at
+ the same page. In addition, <command>Privoxy</command> can be toggled on/off.
+ This is an internal page, and does not require Internet access.

+<para>
+ This is a stable release, and marks a departure for Privoxy development.
+</para>
+<para>
+ Previously, odd numbered releases were considered beta versions and
+ were only released at the end of the development cycle when the code
+ was already believed to be stable. Usually it was, so the stable release
+ contained pretty much the same code, but got a higher version number.
+ In the future we intend to release several snapshots between stable releases.
+ There will probably still be about two stable releases per year,
+ but hopefully about six snapshots instead of the two betas we have now.
+ The intentions is to make testing without CVS access easier.

+<title>Quickstart to Ad Blocking</title>
+<!--
+ NOTE: This section is deliberately redundant for those that don't
+ want to read the whole thing (which is getting lengthy).
+-->
+<para>
+ Ad blocking is but one of <application>Privoxy's</application>
+ array of features. Many of these features are for the technically minded advanced
+ user. But, ad and banner blocking is surely common ground for everybody.
+</para>
+<para>
+ This section will provide a quick summary of ad blocking so
+ you can get up to speed quickly without having to read the more extensive
+ information provided below, though this is highly recommended.
+</para>
+<para>
+ First a bit of a warning ... blocking ads is much like blocking SPAM: the
+ more aggressive you are about it, the more likely you are to block
+ things that were not intended. And the more likely that some things
+ may not work as intended. So there is a trade off here. If you want
+ extreme ad free browsing, be prepared to deal with more
+ <quote>problem</quote> sites, and to spend more time adjusting the
+ configuration to solve these unintended consequences. In short, there is
+ not an easy way to eliminate <emphasis>all</emphasis> ads. Either take
+ the easy way and settle for <emphasis>most</emphasis> ads blocked with the
+ default configuration, or jump in and tweak it for your personal surfing
+ habits and preferences.
+</para>
+<para>
+ Secondly, a brief explanation of <application>Privoxy's </application>
+ <quote>actions</quote>. <quote>Actions</quote> in this context, are
+ the directives we use to tell <application>Privoxy</application> to perform
+ some task relating to HTTP transactions (i.e. web browsing). We tell
+ <application>Privoxy</application> to take some <quote>action</quote>. Each
+ action has a unique name and function. While there are many potential
+ <application>actions</application> in <application>Privoxy's</application>
+ arsenal, only a few are used for ad blocking. <link
+ linkend="actions">Actions</link>, and <link linkend="actions-file">action
+ configuration files</link>, are explained in depth below.
+</para>
+<para>
+ Actions are specified in <application>Privoxy's</application> configuration,
+ followed by one or more URLs to which the action should apply. URLs
+ can actually be URL type <link linkend="af-patterns">patterns</link> that use
+ wildcards so they can apply potentially to a range of similar URLs. The
+ actions, together with the URL patterns are called a section.
+</para>
+<para>
+ When you connect to a website, the full URL will either match one or more
+ of the sections as defined in <application>Privoxy's</application> configuration,
+ or not. If so, then <application>Privoxy</application> will perform the
+ respective actions. If not, then nothing special happens. Furthermore, web
+ pages may contain embedded, secondary URLs that your web browser will
+ use to load additional components of the page, as it parses the
+ original page's HTML content. An ad image for instance, is just an URL
+ embedded in the page somewhere. The image itself may be on the same server,
+ or a server somewhere else on the Internet. Complex web pages will have many
+ such embedded URLs. &my-app; can deal with each URL individually, so, for
+ instance, the main page text is not touched, but images from such-and-such
+ server are blocked.
+</para>
+
+<para>
+ The most important actions for basic ad blocking are: <literal><link
+ linkend="block">block</link></literal>, <literal><link
+ linkend="handle-as-image">handle-as-image</link></literal>,
+ <literal><link
+ linkend="handle-as-empty-document">handle-as-empty-document</link></literal>,and
+ <literal><link linkend="set-image-blocker">set-image-blocker</link></literal>:
+</para>
+
+<para>
+ <itemizedlist>
+
+ <listitem>
+ <para>
+ <literal><link linkend="block">block</link></literal> - this is perhaps
+ the single most used action, and is particularly important for ad blocking.
+ This action stops any contact between your browser and any URL patterns
+ that match this action's configuration. It can be used for blocking ads,
+ but also anything that is determined to be unwanted. By itself, it simply
+ stops any communication with the remote server and sends
+ <application>Privoxy</application>'s own built-in BLOCKED page instead to
+ let you now what has happened (with some exceptions, see below).
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ <literal><link linkend="handle-as-image">handle-as-image</link></literal> -
+ tells <application>Privoxy</application> to treat this URL as an image.
+ <application>Privoxy</application>'s default configuration already does this
+ for all common image types (e.g. GIF), but there are many situations where this
+ is not so easy to determine. So we'll force it in these cases. This is particularly
+ important for ad blocking, since only if we know that it's an image of
+ some kind, can we replace it with an image of our choosing, instead of the
+ <application>Privoxy</application> BLOCKED page (which would only result in
+ a <quote>broken image</quote> icon). There are some limitations to this
+ though. For instance, you can't just brute-force an image substitution for
+ an entire HTML page in most situations.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ <literal><link linkend="handle-as-empty-document">handle-as-empty-document</link></literal> -
+ sends an empty document instead of <application>Privoxy's</application>
+ normal BLOCKED HTML page. This is useful for file types that are neither
+ HTML nor images, such as blocking JavaScript files.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ <literal><link
+ linkend="set-image-blocker">set-image-blocker</link></literal> - tells
+ <application>Privoxy</application> what to display in place of an ad image that
+ has hit a block rule. For this to come into play, the URL must match a
+ <literal><link linkend="block">block</link></literal> action somewhere in the
+ configuration, <emphasis>and</emphasis>, it must also match an
+ <literal><link linkend="handle-as-image">handle-as-image</link></literal> action.
+ </para>
+ <para>
+ The configuration options on what to display instead of the ad are:
+ </para>
+ <simplelist>
+ <member>
+ <emphasis>pattern</emphasis> - a checkerboard pattern, so that an ad
+ replacement is obvious. This is the default.
+ </member>
+ </simplelist>
+ <simplelist>
+ <member>
+ <emphasis>blank</emphasis> - A very small empty GIF image is displayed.
+ This is the so-called <quote>invisible</quote> configuration option.
+ </member>
+ </simplelist>
+ <simplelist>
+ <member>
+ <emphasis>http://<URL></emphasis> - A redirect to any image anywhere
+ of the user's choosing (advanced usage).
+ </member>
+ </simplelist>
+ </listitem>
+
+</itemizedlist>
+</para>
+
+<para>
+ Advanced users will eventually want to explore &my-app;
+ <literal><link linkend="filter">filters</link></literal> as well. Filters
+ are very different from <literal><link
+ linkend="block">blocks</link></literal>.
+ A <quote>block</quote> blocks a site, page, or unwanted contented. Filters
+ are a way of filtering or modifying what is actually on the page. An example
+ filter usage: a text replacement of <quote>no-no</quote> for
+ <quote>nasty-word</quote>. That is a very simple example. This process can be
+ used for ad blocking, but it is more in the realm of advanced usage and has
+ some pitfalls to be wary off.
+</para>
+
+<para>
+ The quickest way to adjust any of these settings is with your browser through
+ the special <application>Privoxy</application> editor at <ulink
+ url="http://config.privoxy.org/show-status">http://config.privoxy.org/show-status</ulink>
+ (shortcut: <ulink url="http://p.p/">http://p.p/show-status</ulink>). This
+ is an internal page, and does not require Internet access.
+</para>
+
+<para>
+ Note that as of <application>Privoxy</application> 3.0.7 beta the
+ action editor is disabled by default. Check the
+ <ulink url="config.html#ENABLE-EDIT-ACTIONS">enable-edit-actions
+ section in the configuration file</ulink> to learn why and in which
+ cases it's safe to enable again.
+</para>
+
+<para>
+ If you decided to enable the action editor, select the appropriate
+ <quote>actions</quote> file, and click
+ <quote><guibutton>Edit</guibutton></quote>. It is best to put personal or
+ local preferences in <filename>user.action</filename> since this is not
+ meant to be overwritten during upgrades, and will over-ride the settings in
+ other files. Here you can insert new <quote>actions</quote>, and URLs for ad
+ blocking or other purposes, and make other adjustments to the configuration.
+ <application>Privoxy</application> will detect these changes automatically.

+ The included default configuration files should give a reasonable starting
+ point. Most of the per site configuration is done in the
+ <ulink url="actions-file.html"><quote>actions</quote></ulink> files. These are

+ You will probably want to keep an eye out for sites for which you may prefer
+ persistent cookies, and add these to your actions configuration as needed. By
+ default, most of these will be accepted only during the current browser
+ session (aka <quote>session cookies</quote>), unless you add them to the
+ configuration. If you want the browser to handle this instead, you will need
+ to edit <filename>user.action</filename> (or through the web based interface)
+ and disable this feature. If you use more than one browser, it would make

+ Another feature where you will probably want to define exceptions for trusted
+ sites is the popup-killing (through <ulink

+ try to force HTTP/1.0 compatibility. For Mozilla, look under <literal>Edit ->
+ Preferences -> Debug -> Networking</literal>.
+ Alternatively, set the <quote>+downgrade-http-version</quote> config option in

+ The list of actions files to be used are defined in the main configuration
+ file, and are processed in the order they are defined (e.g.
+ <filename>default.action</filename> is typically processed before
+ <filename>user.action</filename>). The content of these can all be viewed and
+ edited from <ulink
+ url="http://config.privoxy.org/show-status">http://config.privoxy.org/show-status</ulink>.
+ The over-riding principle when applying actions, is that the last action that
+ matches a given URL wins. The broadest, most general rules go first
+ (defined in <filename>default.action</filename>),
+ followed by any exceptions (typically also in
+ <filename>default.action</filename>), which are then followed lastly by any
+ local preferences (typically in <emphasis>user</emphasis><filename>.action</filename>).
+ Generally, <filename>user.action</filename> has the last word.
+ </para>
+
+<para>
+ An actions file typically has multiple sections. If you want to use
+ <quote>aliases</quote> in an actions file, you have to place the (optional)
+ <link linkend="aliases">alias section</link> at the top of that file.
+ Then comes the default set of rules which will apply universally to all
+ sites and pages (be <emphasis>very careful</emphasis> with using such a
+ universal set in <filename>user.action</filename> or any other actions file after
+ <filename>default.action</filename>, because it will override the result
+ from consulting any previous file). And then below that,
+ exceptions to the defined universal policies. You can regard
+ <filename>user.action</filename> as an appendix to <filename>default.action</filename>,
+ with the advantage that it is a separate file, which makes preserving your
+ personal settings across <application>Privoxy</application> upgrades easier.
+</para>
+
+<para>
+ Actions can be used to block anything you want, including ads, banners, or
+ just some obnoxious URL whose content you would rather not see. Cookies can be accepted
+ or rejected, or accepted only during the current browser session (i.e. not
+ written to disk), content can be modified, some JavaScripts tamed, user-tracking
+ fooled, and much more. See below for a <link linkend="actions">complete list
+ of actions</link>.

+<title>Finding the Right Mix</title>
+<para>
+ Note that some <link linkend="actions">actions</link>, like cookie suppression
+ or script disabling, may render some sites unusable that rely on these
+ techniques to work properly. Finding the right mix of actions is not always easy and
+ certainly a matter of personal taste. And, things can always change, requiring
+ refinements in the configuration. In general, it can be said that the more
+ <quote>aggressive</quote> your default settings (in the top section of the
+ actions file) are, the more exceptions for <quote>trusted</quote> sites you
+ will have to make later. If, for example, you want to crunch all cookies per
+ default, you'll have to make exceptions from that rule for sites that you
+ regularly use and that require cookies for actually useful purposes, like maybe

+<title>How to Edit</title>
+<para>
+ The easiest way to edit the actions files is with a browser by
+ using our browser-based editor, which can be reached from <ulink
+ url="http://config.privoxy.org/show-status">http://config.privoxy.org/show-status</ulink>.
+ Note: the config file option <link
+ linkend="enable-edit-actions">enable-edit-actions</link> must be enabled for
+ this to work. The editor allows both fine-grained control over every single
+ feature on a per-URL basis, and easy choosing from wholesale sets of defaults
+ like <quote>Cautious</quote>, <quote>Medium</quote> or
+ <quote>Advanced</quote>. Warning: the <quote>Advanced</quote> setting is more
+ aggressive, and will be more likely to cause problems for some sites.
+ Experienced users only!
+ </para>
+
+<para>
+ If you prefer plain text editing to GUIs, you can of course also directly edit the
+ the actions files with your favorite text editor. Look at
+ <filename>default.action</filename> which is richly commented with many
+ good examples.

+<sect2 id="actions-apply">
+<title>How Actions are Applied to Requests</title>
+<para>
+ Actions files are divided into sections. There are special sections,
+ like the <quote><link linkend="aliases">alias</link></quote> sections which will
+ be discussed later. For now let's concentrate on regular sections: They have a
+ heading line (often split up to multiple lines for readability) which consist
+ of a list of actions, separated by whitespace and enclosed in curly braces.
+ Below that, there is a list of URL and tag patterns, each on a separate line.
+</para>
+
+<para>
+ To determine which actions apply to a request, the URL of the request is
+ compared to all URL patterns in each <quote>action file</quote>.
+ Every time it matches, the list of applicable actions for the request is
+ incrementally updated, using the heading of the section in which the
+ pattern is located. The same is done again for tags and tag patterns later on.
+</para>
+
+<para>
+ If multiple applying sections set the same action differently,
+ the last match wins. If not, the effects are aggregated.
+ E.g. a URL might match a regular section with a heading line of <literal>{
+ +<link linkend="handle-as-image">handle-as-image</link> }</literal>,
+ then later another one with just <literal>{
+ +<link linkend="block">block</link> }</literal>, resulting
+ in <emphasis>both</emphasis> actions to apply. And there may well be
+ cases where you will want to combine actions together. Such a section then
+ might look like:
+</para>
+
+ <para>
+ <screen>
+ { +<literal>handle-as-image</literal> +<literal>block{Banner ads.}</literal> }
+ # Block these as if they were images. Send no block page.
+ banners.example.com
+ media.example.com/.*banners
+ .example.com/images/ads/</screen>
+ </para>

+<title>Patterns</title>
+<para>
+ As mentioned, <application>Privoxy</application> uses <quote>patterns</quote>
+ to determine what <emphasis>actions</emphasis> might apply to which sites and

+ Generally, an URL pattern has the form
+ <literal><domain>/<path></literal>, where both the
+ <literal><domain></literal> and <literal><path></literal> are
+ optional. (This is why the special <literal>/</literal> pattern matches all
+ URLs). Note that the protocol portion of the URL pattern (e.g.
+ <literal>http://</literal>) should <emphasis>not</emphasis> be included in
+ the pattern. This is assumed already!
+</para>
+<para>
+ The pattern matching syntax is different for the domain and path parts of

+<sect3><title>The Domain Pattern</title>
+
+<para>
+ The matching of the domain part offers some flexible options: if the
+ domain starts or ends with a dot, it becomes unanchored at that end.
+ For example:
+</para>
+
+<variablelist>
+ <varlistentry>
+ <term><literal>.example.com</literal></term>
+ <listitem>
+ <para>
+ matches any domain with first-level domain <literal>com</literal>
+ and second-level domain <literal>example</literal>.
+ For example <literal>www.example.com</literal>,
+ <literal>example.com</literal> and <literal>foo.bar.baz.example.com</literal>.
+ Note that it wouldn't match if the second-level domain was <literal>another-example</literal>.
+ </para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term><literal>www.</literal></term>
+ <listitem>
+ <para>
+ matches any domain that <emphasis>STARTS</emphasis> with
+ <literal>www.</literal> (It also matches the domain
+ <literal>www</literal> but most of the time that doesn't matter.)
+ </para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term><literal>.example.</literal></term>
+ <listitem>
+ <para>
+ matches any domain that <emphasis>CONTAINS</emphasis> <literal>.example.</literal>.
+ And, by the way, also included would be any files or documents that exist
+ within that domain since no path limitations are specified. (Correctly
+ speaking: It matches any FQDN that contains <literal>example</literal> as
+ a domain.) This might be <literal>www.example.com</literal>,
+ <literal>news.example.de</literal>, or
+ <literal>www.example.net/cgi/testing.pl</literal> for instance. All these
+ cases are matched.
+ </para>
+ </listitem>
+ </varlistentry>
+</variablelist>
+
+<para>
+ Additionally, there are wild-cards that you can use in the domain names
+ themselves. These work similarly to shell globbing type wild-cards:
+ <quote>*</quote> represents zero or more arbitrary characters (this is
+ equivalent to the
+ <ulink url="http://en.wikipedia.org/wiki/Regular_expressions"><quote>Regular
+ Expression</quote></ulink> based syntax of <quote>.*</quote>),
+ <quote>?</quote> represents any single character (this is equivalent to the
+ regular expression syntax of a simple <quote>.</quote>), and you can define
+ <quote>character classes</quote> in square brackets which is similar to
+ the same regular expression technique. All of this can be freely mixed:
+</para>
+
+<variablelist>
+ <varlistentry>
+ <term><literal>ad*.example.com</literal></term>
+ <listitem>
+ <para>
+ matches <quote>adserver.example.com</quote>,
+ <quote>ads.example.com</quote>, etc but not <quote>sfads.example.com</quote>
+ </para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term><literal>*ad*.example.com</literal></term>
+ <listitem>
+ <para>
+ matches all of the above, and then some.
+ </para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term><literal>.?pix.com</literal></term>
+ <listitem>
+ <para>

+<sect3 id="tag-pattern"><title>The Tag Pattern</title>
+
+<para>
+ Tag patterns are used to change the applying actions based on the
+ request's tags. Tags can be created with either the
+ <link linkend="CLIENT-HEADER-TAGGER">client-header-tagger</link>
+ or the <link linkend="SERVER-HEADER-TAGGER">server-header-tagger</link> action.
+</para>
+
+<para>
+ Tag patterns have to start with <quote>TAG:</quote>, so &my-app;
+ can tell them apart from URL patterns. Everything after the colon
+ including white space, is interpreted as a regular expression with
+ path pattern syntax, except that tag patterns aren't left-anchored
+ automatically (&my-app; doesn't silently add a <quote>^</quote>,
+ you have to do it yourself if you need it).
+</para>
+
+<para>
+ To match all requests that are tagged with <quote>foo</quote>
+ your pattern line should be <quote>TAG:^foo$</quote>,
+ <quote>TAG:foo</quote> would work as well, but it would also
+ match requests whose tags contain <quote>foo</quote> somewhere.
+ <quote>TAG: foo</quote> wouldn't work as it requires white space.
+</para>
+
+<para>
+ Sections can contain URL and tag patterns at the same time,
+ but tag patterns are checked after the URL patterns and thus
+ always overrule them, even if they are located before the URL patterns.
+</para>
+
+<para>
+ Once a new tag is added, Privoxy checks right away if it's matched by one
+ of the tag patterns and updates the action settings accordingly. As a result
+ tags can be used to activate other tagger actions, as long as these other
+ taggers look for headers that haven't already be parsed.
+</para>
+
+<para>
+ For example you could tag client requests which use the
+ <literal>POST</literal> method,
+ then use this tag to activate another tagger that adds a tag if cookies
+ are sent, and then use a block action based on the cookie tag. This allows
+ the outcome of one action, to be input into a subsequent action. However if
+ you'd reverse the position of the described taggers, and activated the
+ method tagger based on the cookie tagger, no method tags would be created.
+ The method tagger would look for the request line, but at the time
+ the cookie tag is created, the request line has already been parsed.
+</para>
+
+<para>
+ While this is a limitation you should be aware of, this kind of
+ indirection is seldom needed anyway and even the example doesn't
+ make too much sense.

+<para>
+ All actions are disabled by default, until they are explicitly enabled
+ somewhere in an actions file. Actions are turned on if preceded with a
+ <quote>+</quote>, and turned off if preceded with a <quote>-</quote>. So a

+ previously applied.</quote>
+
+</para>
+
+<para>
+ Again, actions are invoked by placing them on a line, enclosed in curly braces and
+ separated by whitespace, like in
+ <literal>{+some-action -some-other-action{some-parameter}}</literal>,
+ followed by a list of URL patterns, one per line, to which they apply.
+ Together, the actions line and the following pattern lines make up a section

+
+<para>
+ <itemizedlist>
+ <listitem>
+ <para>
+ Boolean, i.e the action can only be <quote>enabled</quote> or

+ </para>
+ <para>
+ Note that if the URL matches multiple positive forms of a parameterized action,

+ </listitem>
+
+ <listitem>
+ <para>
+ Multi-value. These look exactly like parameterized actions,
+ but they behave differently: If the action applies multiple times to the

+ from <emphasis>all</emphasis> matches are remembered. This is used for actions
+ that can be executed for the same request repeatedly, like adding multiple

+ </para>
+ <para>
+ <screen>
+ +<replaceable class="function">name</replaceable>{<replaceable class="parameter">param</replaceable>} # enable action and add <replaceable class="parameter">param</replaceable> to the list of parameters

+ </para>
+ </listitem>
+
+ </itemizedlist>
+</para>
+
+<para>
+ If nothing is specified in any actions file, no <quote>actions</quote> are
+ taken. So in this case <application>Privoxy</application> would just be a
+ normal, non-blocking, non-filtering proxy. You must specifically enable the
+ privacy and blocking features you need (although the provided default actions
+ files will give a good starting point).
+</para>
+
+<para>
+ Later defined action sections always over-ride earlier ones of the same type.
+ So exceptions to any rules you make, should come in the latter part of the file (or
+ in a file that is processed later when using multiple actions files such
+ as <filename>user.action</filename>). For multi-valued actions, the actions
+ are applied in the order they are specified. Actions files are processed in

+ <para>
+ Many sites, like yahoo.com, don't just link to other sites. Instead, they
+ will link to some script on their own servers, giving the destination as a
+ parameter, which will then redirect you to the final target. URLs
+ resulting from this scheme typically look like:
+ <quote>http://www.example.org/click-tracker.cgi?target=http%3a//www.example.net/</quote>.
+ </para>
+ <para>
+ Sometimes, there are even multiple consecutive redirects encoded in the
+ URL. These redirections via scripts make your web browsing more traceable,
+ since the server from which you follow such a link can see where you go
+ to. Apart from that, valuable bandwidth and time is wasted, while your
+ browser asks the server for one redirect after the other. Plus, it feeds
+ the advertisers.
+ </para>
+ <para>
+ This feature is currently not very smart and is scheduled for improvement.
+ If it is enabled by default, you will have to create some exceptions to
+ this action. It can lead to failures in several ways:
+ </para>
+ <para>
+ Not every URLs with other URLs as parameters is evil.
+ Some sites offer a real service that requires this information to work.
+ For example a validation service needs to know, which document to validate.
+ <literal>fast-redirects</literal> assumes that every URL parameter that
+ looks like another URL is a redirection target, and will always redirect to
+ the last one. Most of the time the assumption is correct, but if it isn't,
+ the user gets redirected anyway.
+ </para>
+ <para>
+ Another failure occurs if the URL contains other parameters after the URL parameter.
+ The URL:
+ <quote>http://www.example.org/?redirect=http%3a//www.example.net/&foo=bar</quote>.
+ contains the redirection URL <quote>http://www.example.net/</quote>,
+ followed by another parameter. <literal>fast-redirects</literal> doesn't know that
+ and will cause a redirect to <quote>http://www.example.net/&foo=bar</quote>.
+ Depending on the target server configuration, the parameter will be silently ignored
+ or lead to a <quote>page not found</quote> error. You can prevent this problem by
+ first using the <literal><link linkend="redirect">redirect</link></literal> action
+ to remove the last part of the URL, but it requires a little effort.
+ </para>
+ <para>
+ To detect a redirection URL, <literal>fast-redirects</literal> only
+ looks for the string <quote>http://</quote>, either in plain text
+ (invalid but often used) or encoded as <quote>http%3a//</quote>.
+ Some sites use their own URL encoding scheme, encrypt the address
+ of the target server or replace it with a database id. In theses cases
+ <literal>fast-redirects</literal> is fooled and the request reaches the
+ redirection server where it probably gets logged.

+ Filtering requires buffering the page content, which may appear to

+ The amount of data that can be filtered is limited to the
+ <literal><link linkend="buffer-limit">buffer-limit</link></literal>
+ option in the main <link linkend="config">config file</link>. The
+ default is 4096 KB (4 Megs). Once this limit is exceeded, the buffered
+ data, and all pending data, is passed through unfiltered.
+ </para>
+ <para>
+ Inappropriate MIME types, such as zipped files, are not filtered at all.
+ (Again, only text-based types except plain text). Encrypted SSL data
+ (from HTTPS servers) cannot be filtered either, since this would violate
+ the integrity of the secure transaction. In some situations it might
+ be necessary to protect certain text, like source code, from filtering
+ by defining appropriate <literal>-filter</literal> exceptions.
+ </para>
+ <para>
+ Compressed content can't be filtered either, unless &my-app;
+ is compiled with zlib support (requires at least &my-app; 3.0.7),
+ in which case &my-app; will decompress the content before filtering
+ it.
+ </para>
+ <para>
+ If you use a &my-app; version without zlib support, but want filtering to work on
+ as much documents as possible, even those that would normally be sent compressed,
+ you must use the <literal><link linkend="prevent-compression">prevent-compression</link></literal>

+ Content filtering can achieve some of the same effects as the

+ Removing the <quote>Last-Modified:</quote> header is useful for filter
+ testing, where you want to force a real reload instead of getting status
+ code <quote>304</quote>, which would cause the browser to reuse the old
+ version of the page.
+ </para>
+ <para>
+ The <quote>randomize</quote> option overwrites the value of the
+ <quote>Last-Modified:</quote> header with a randomly chosen time
+ between the original value and the current time. In theory the server
+ could send each document with a different <quote>Last-Modified:</quote>
+ header to track visits without using cookies. <quote>Randomize</quote>
+ makes it impossible and the browser can still revalidate cached documents.
+ </para>
+ <para>
+ <quote>reset-to-request-time</quote> overwrites the value of the
+ <quote>Last-Modified:</quote> header with the current time. You could use
+ this option together with
+ <literal><link linkend="hide-if-modified-since">hide-if-modified-since</link></literal>
+ to further customize your random range.
+ </para>
+ <para>
+ The preferred parameter here is <quote>randomize</quote>. It is safe
+ to use, as long as the time settings are more or less correct.
+ If the server sets the <quote>Last-Modified:</quote> header to the time
+ of the request, the random range becomes zero and the value stays the same.

+<title>Aliases</title>
+<para>
+ Custom <quote>actions</quote>, known to <application>Privoxy</application>
+ as <quote>aliases</quote>, can be defined by combining other actions.
+ These can in turn be invoked just like the built-in actions.
+ Currently, an alias name can contain any character except space, tab,
+ <quote>=</quote>,
+ <quote>{</quote> and <quote>}</quote>, but we <emphasis>strongly
+ recommend</emphasis> that you only use <quote>a</quote> to <quote>z</quote>,
+ <quote>0</quote> to <quote>9</quote>, <quote>+</quote>, and <quote>-</quote>.
+ Alias names are not case sensitive, and are not required to start with a
+ <quote>+</quote> or <quote>-</quote> sign, since they are merely textually
+ expanded.
+</para>
+<para>
+ Aliases can be used throughout the actions file, but they <emphasis>must be
+ defined in a special section at the top of the file!</emphasis>
+ And there can only be one such section per actions file. Each actions file may
+ have its own alias section, and the aliases defined in it are only visible
+ within that file.
+</para>
+<para>
+ There are two main reasons to use aliases: One is to save typing for frequently
+ used combinations of actions, the other one is a gain in flexibility: If you
+ decide once how you want to handle shops by defining an alias called
+ <quote>shop</quote>, you can later change your policy on shops in
+ <emphasis>one</emphasis> place, and your changes will take effect everywhere
+ in the actions file where the <quote>shop</quote> alias is used. Calling aliases
+ by their purpose also makes your actions files more readable.
+</para>
+<para>
+ Currently, there is one big drawback to using aliases, though:
+ <application>Privoxy</application>'s built-in web-based action file
+ editor honors aliases when reading the actions files, but it expands
+ them before writing. So the effects of your aliases are of course preserved,
+ but the aliases themselves are lost when you edit sections that use aliases
+ with it.
+</para>
+
+<para>
+ Now let's define some aliases...
+</para>
+
+<para>
+ <screen>
+ # Useful custom aliases we can use later.
+ #
+ # Note the (required!) section header line and that this section
+ # must be at the top of the actions file!

+
+<para>
+ The first of our specialized sections is concerned with <quote>fragile</quote>
+ sites, i.e. sites that require minimum interference, because they are either
+ very complex or very keen on tracking you (and have mechanisms in place that
+ make them unusable for people who avoid being tracked). We will simply use

+ Shopping sites are not as fragile, but they typically

+ The <literal><link linkend="FAST-REDIRECTS">fast-redirects</link></literal>

+<para>
+ It is important that <application>Privoxy</application> knows which
+ URLs belong to images, so that <emphasis>if</emphasis> they are to
+ be blocked, a substitute image can be sent, rather than an HTML page.
+ Contacting the remote site to find out is not an option, since it
+ would destroy the loading time advantage of banner blocking, and it
+ would feed the advertisers information about you. We can mark any
+ URL as an image with the <literal><link
+ linkend="handle-as-image">handle-as-image</link></literal> action,
+ and marking all URLs that end in a known image file extension is a
+ good start:
+</para>
+
+<para>
+ <screen>
+##########################################################################
+# Images:
+##########################################################################
+
+# Define which file types will be treated as images, in case they get
+# blocked further down this file:

+{ +<link linkend="HANDLE-AS-IMAGE">handle-as-image</link> }
+/.*\.(gif|jpe?g|png|bmp|ico)$</screen>
+</para>
+
+<para>
+ And then there are known banner sources. They often use scripts to
+ generate the banners, so it won't be visible from the URL that the
+ request is for an image. Hence we block them <emphasis>and</emphasis>
+ mark them as images in one go, with the help of our
+ <literal>+block-as-image</literal> alias defined above. (We could of
+ course just as well use <literal>+<link linkend="block">block</link>
+ +<link linkend="handle-as-image">handle-as-image</link></literal> here.)
+ Remember that the type of the replacement image is chosen by the
+ <literal><link linkend="set-image-blocker">set-image-blocker</link></literal>
+ action. Since all URLs have matched the default section with its
+ <literal>+<link linkend="set-image-blocker">set-image-blocker</link>{pattern}</literal>
+ action before, it still applies and needn't be repeated:
+</para>
+
+<para>

+</para>
+
+<para>
+ One of the most important jobs of <application>Privoxy</application>
+ is to block banners. Many of these can be <quote>blocked</quote>
+ by the <literal><link linkend="filter">filter</link>{banners-by-size}</literal>
+ action, which we enabled above, and which deletes the references to banner
+ images from the pages while they are loaded, so the browser doesn't request
+ them anymore, and hence they don't need to be blocked here. But this naturally
+ doesn't catch all banners, and some people choose not to use filters, so we
+ need a comprehensive list of patterns for banner URLs here, and apply the
+ <literal><link linkend="block">block</link></literal> action to them.
+</para>
+<para>
+ First comes many generic patterns, which do most of the work, by
+ matching typical domain and path name components of banners. Then comes
+ a list of individual patterns for specific sites, which is omitted here
+ to keep the example short:
+</para>
+
+<para>
+ <screen>
+##########################################################################
+# Block these fine banners:
+##########################################################################
+{ <link linkend="BLOCK">+block{Banner ads.}</link> }
+
+# Generic patterns:
+#
+ad*.
+.*ads.
+banner?.
+count*.
+/.*count(er)?\.(pl|cgi|exe|dll|asp|php[34]?)
+/(?:.*/)?(publicite|werbung|rekla(ma|me|am)|annonse|maino(kset|nta|s)?)/
+
+# Site-specific patterns (abbreviated):
+#
+.hitbox.com</screen>
+</para>
+
+<para>
+ It's quite remarkable how many advertisers actually call their banner
+ servers ads.<replaceable>company</replaceable>.com, or call the directory
+ in which the banners are stored simply <quote>banners</quote>. So the above
+ generic patterns are surprisingly effective.
+</para>
+<para>
+ But being very generic, they necessarily also catch URLs that we don't want
+ to block. The pattern <literal>.*ads.</literal> e.g. catches
+ <quote>nasty-<emphasis>ads</emphasis>.nasty-corp.com</quote> as intended,
+ but also <quote>downlo<emphasis>ads</emphasis>.sourcefroge.net</quote> or
+ <quote><emphasis>ads</emphasis>l.some-provider.net.</quote> So here come some
+ well-known exceptions to the <literal>+<link linkend="BLOCK">block</link></literal>
+ section above.
+</para>
+<para>
+ Note that these are exceptions to exceptions from the default! Consider the URL
+ <quote>downloads.sourcefroge.net</quote>: Initially, all actions are deactivated,
+ so it wouldn't get blocked. Then comes the defaults section, which matches the
+ URL, but just deactivates the <literal><link linkend="BLOCK">block</link></literal>
+ action once again. Then it matches <literal>.*ads.</literal>, an exception to the
+ general non-blocking policy, and suddenly
+ <literal><link linkend="BLOCK">+block</link></literal> applies. And now, it'll match
+ <literal>.*loads.</literal>, where <literal><link linkend="BLOCK">-block</link></literal>
+ applies, so (unless it matches <emphasis>again</emphasis> further down) it ends up
+ with no <literal><link linkend="BLOCK">block</link></literal> action applying.
+</para>

+ So far we are painting with a broad brush by setting general policies,
+ which would be a reasonable starting point for many people. Now,
+ you might want to be more specific and have customized rules that
+ are more suitable to your personal habits and preferences. These would
+ be for narrowly defined situations like your ISP or your bank, and should
+ be placed in <filename>user.action</filename>, which is parsed after all other
+ actions files and hence has the last word, over-riding any previously
+ defined actions. <filename>user.action</filename> is also a
+ <emphasis>safe</emphasis> place for your personal settings, since

+ Example of a simple <link linkend="BLOCK">block</link> action. Say you've

+ The URLs of dynamically generated banners, especially from large banner

+ On-the-fly text substitutions need

+</para>
+
+<para>
+ &my-app; supports three different filter actions:
+ <literal><link linkend="filter">filter</link></literal> to
+ rewrite the content that is send to the client,
+ <literal><link linkend="client-header-filter">client-header-filter</link></literal>
+ to rewrite headers that are send by the client, and
+ <literal><link linkend="server-header-filter">server-header-filter</link></literal>
+ to rewrite headers that are send by the server.
+</para>
+
+<para>
+ &my-app; also supports two tagger actions:
+ <literal><link linkend="client-header-tagger">client-header-tagger</link></literal>
+ and
+ <literal><link linkend="server-header-tagger">server-header-tagger</link></literal>.
+ Taggers and filters use the same syntax in the filter files, the difference
+ is that taggers don't modify the text they are filtering, but use a rewritten
+ version of the filtered text as tag. The tags can then be used to change the
+ applying actions through sections with <link linkend="tag-pattern">tag-patterns</link>.
+</para>
+
+
+<para>
+ Multiple filter files can be defined through the <literal> <link
+ linkend="filterfile">filterfile</link></literal> config directive. The filters
+ as supplied by the developers are located in
+ <filename>default.filter</filename>. It is recommended that any locally
+ defined or modified filters go in a separately defined file such as
+ <filename>user.filter</filename>.
+ </para>
+
+<para>
+ Common tasks for content filters are to eliminate common annoyances in
+ HTML and JavaScript, such as pop-up windows,
+ exit consoles, crippled windows without navigation tools, the
+ infamous <BLINK> tag etc, to suppress images with certain
+ width and height attributes (standard banner sizes or web-bugs),
+ or just to have fun.
+</para>
+
+<para>
+ Enabled content filters are applied to any content whose
+ <quote>Content Type</quote> header is recognised as a sign
+ of text-based content, with the exception of <literal>text/plain</literal>.
+ Use the <link linkend="FORCE-TEXT-MODE">force-text-mode</link> action
+ to also filter other content.
+</para>
+
+<para>
+ Substitutions are made at the source level, so if you want to <quote>roll
+ your own</quote> filters, you should first be familiar with HTML syntax,
+ and, of course, regular expressions.
+</para>
+
+<para>
+ Just like the <link linkend="actions-file">actions files</link>, the
+ filter file is organized in sections, which are called <emphasis>filters</emphasis>
+ here. Each filter consists of a heading line, that starts with one of the
+ <emphasis>keywords</emphasis> <literal>FILTER:</literal>,
+ <literal>CLIENT-HEADER-FILTER:</literal> or <literal>SERVER-HEADER-FILTER:</literal>
+ followed by the filter's <emphasis>name</emphasis>, and a short (one line)
+ <emphasis>description</emphasis> of what it does. Below that line
+ come the <emphasis>jobs</emphasis>, i.e. lines that define the actual
+ text substitutions. By convention, the name of a filter
+ should describe what the filter <emphasis>eliminates</emphasis>. The
+ comment is used in the <ulink url="http://config.privoxy.org/">web-based
+ user interface</ulink>.
+</para>
+
+<para>
+ Once a filter called <replaceable>name</replaceable> has been defined
+ in the filter file, it can be invoked by using an action of the form
+ +<literal><link linkend="filter">filter</link>{<replaceable>name</replaceable>}</literal>
+ in any <link linkend="actions-file">actions file</link>.
+</para>
+
+<para>
+ Filter definitions start with a header line that contains the filter
+ type, the filter name and the filter description.
+ A content filter header line for a filter called <quote>foo</quote> could look
+ like this:
+</para>
+
+<para>
+ <screen>FILTER: foo Replace all "foo" with "bar"</screen>
+</para>
+
+<para>
+ Below that line, and up to the next header line, come the jobs that
+ define what text replacements the filter executes. They are specified
+ in a syntax that imitates <ulink url="http://www.perl.org/">Perl</ulink>'s
+ <literal>s///</literal> operator. If you are familiar with Perl, you
+ will find this to be quite intuitive, and may want to look at the
+ PCRS documentation for the subtle differences to Perl behaviour. Most
+ notably, the non-standard option letter <literal>U</literal> is supported,
+ which turns the default to ungreedy matching.
+</para>
+
+<para>
+ If you are new to
+ <ulink url="http://en.wikipedia.org/wiki/Regular_expressions"><quote>Regular

+ Now, let's complete our <quote>foo</quote> content filter. We have already defined

+ needed:
+</para>
+
+<para>
+ <screen>s/foo/bar/</screen>
+</para>
+
+<para>
+ But wait! Didn't the comment say that <emphasis>all</emphasis> occurrences
+ of <quote>foo</quote> should be replaced? Our current job will only take
+ care of the first <quote>foo</quote> on each page. For global substitution,
+ we'll need to add the <literal>g</literal> option:
+</para>
+
+<para>
+ <screen>s/foo/bar/g</screen>

+ a filter that protects against some common annoyances that arise from JavaScript
+ abuse. Let's look at its jobs one after the other:
+</para>
+
+
+<para>
+ <screen>
+FILTER: js-annoyances Get rid of particularly annoying JavaScript abuse
+
+# Get rid of JavaScript referrer tracking. Test page: http://www.randomoddness.com/untitled.htm
+#
+s|(<script.*)document\.referrer(.*</script>)|$1"Not Your Business!"$2|Usg</screen>
+</para>
+
+<para>
+ Following the header line and a comment, you see the job. Note that it uses
+ <literal>|</literal> as the delimiter instead of <literal>/</literal>, because
+ the pattern contains a forward slash, which would otherwise have to be escaped
+ by a backslash (<literal>\</literal>).
+</para>
+
+<para>
+ Now, let's examine the pattern: it starts with the text <literal><script.*</literal>
+ enclosed in parentheses. Since the dot matches any character, and <literal>*</literal>
+ means: <quote>Match an arbitrary number of the element left of myself</quote>, this
+ matches <quote><script</quote>, followed by <emphasis>any</emphasis> text, i.e.
+ it matches the whole page, from the start of the first <script> tag.
+</para>
+
+<para>
+ That's more than we want, but the pattern continues: <literal>document\.referrer</literal>
+ matches only the exact string <quote>document.referrer</quote>. The dot needed to
+ be <emphasis>escaped</emphasis>, i.e. preceded by a backslash, to take away its
+ special meaning as a joker, and make it just a regular dot. So far, the meaning is:
+ Match from the start of the first <script> tag in a the page, up to, and including,
+ the text <quote>document.referrer</quote>, if <emphasis>both</emphasis> are present
+ in the page (and appear in that order).
+</para>
+
+<para>
+ But there's still more pattern to go. The next element, again enclosed in parentheses,
+ is <literal>.*</script></literal>. You already know what <literal>.*</literal>
+ means, so the whole pattern translates to: Match from the start of the first <script>
+ tag in a page to the end of the last <script> tag, provided that the text
+ <quote>document.referrer</quote> appears somewhere in between.
+</para>
+
+<para>
+ This is still not the whole story, since we have ignored the options and the parentheses:
+ The portions of the page matched by sub-patterns that are enclosed in parentheses, will be
+ remembered and be available through the variables <literal>$1, $2, ...</literal> in
+ the substitute. The <literal>U</literal> option switches to ungreedy matching, which means
+ that the first <literal>.*</literal> in the pattern will only <quote>eat up</quote> all
+ text in between <quote><script</quote> and the <emphasis>first</emphasis> occurrence
+ of <quote>document.referrer</quote>, and that the second <literal>.*</literal> will
+ only span the text up to the <emphasis>first</emphasis> <quote></script></quote>
+ tag. Furthermore, the <literal>s</literal> option says that the match may span
+ multiple lines in the page, and the <literal>g</literal> option again means that the
+ substitution is global.
+</para>
+
+<para>
+ So, to summarize, the pattern means: Match all scripts that contain the text
+ <quote>document.referrer</quote>. Remember the parts of the script from
+ (and including) the start tag up to (and excluding) the string
+ <quote>document.referrer</quote> as <literal>$1</literal>, and the part following
+ that string, up to and including the closing tag, as <literal>$2</literal>.
+</para>
+
+<para>
+ Now the pattern is deciphered, but wasn't this about substituting things? So
+ lets look at the substitute: <literal>$1"Not Your Business!"$2</literal> is
+ easy to read: The text remembered as <literal>$1</literal>, followed by
+ <literal>"Not Your Business!"</literal> (<emphasis>including</emphasis>
+ the quotation marks!), followed by the text remembered as <literal>$2</literal>.
+ This produces an exact copy of the original string, with the middle part
+ (the <quote>document.referrer</quote>) replaced by <literal>"Not Your
+ Business!"</literal>.
+</para>
+
+<para>
+ The whole job now reads: Replace <quote>document.referrer</quote> by
+ <literal>"Not Your Business!"</literal> wherever it appears inside a
+ <script> tag. Note that this job won't break JavaScript syntax,
+ since both the original and the replacement are syntactically valid
+ string objects. The script just won't have access to the referrer
+ information anymore.
+</para>
+
+<para>
+ We'll show you two other jobs from the JavaScript taming department, but
+ this time only point out the constructs of special interest:
+</para>
+
+<para>
+ <screen>
+# The status bar is for displaying link targets, not pointless blahblah
+#
+s/window\.status\s*=\s*(['"]).*?\1/dUmMy=1/ig</screen>
+</para>
+
+<para>
+ <literal>\s</literal> stands for whitespace characters (space, tab, newline,
+ carriage return, form feed), so that <literal>\s*</literal> means: <quote>zero
+ or more whitespace</quote>. The <literal>?</literal> in <literal>.*?</literal>
+ makes this matching of arbitrary text ungreedy. (Note that the <literal>U</literal>
+ option is not set). The <literal>['"]</literal> construct means: <quote>a single
+ <emphasis>or</emphasis> a double quote</quote>. Finally, <literal>\1</literal> is
+ a back-reference to the first parenthesis just like <literal>$1</literal> above,
+ with the difference that in the <emphasis>pattern</emphasis>, a backslash indicates
+ a back-reference, whereas in the <emphasis>substitute</emphasis>, it's the dollar.
+</para>
+
+<para>
+ So what does this job do? It replaces assignments of single- or double-quoted
+ strings to the <quote>window.status</quote> object with a dummy assignment
+ (using a variable name that is hopefully odd enough not to conflict with
+ real variables in scripts). Thus, it catches many cases where e.g. pointless
+ descriptions are displayed in the status bar instead of the link target when
+ you move your mouse over links.
+</para>
+
+<para>
+ <screen>
+# Kill OnUnload popups. Yummy. Test: http://www.zdnet.com/zdsubs/yahoo/tree/yfs.html
+#
+s/(<body [^>]*)onunload(.*>)/$1never$2/iU</screen>
+</para>
+
+<para>
+ Including the
+ <ulink url="http://www.w3.org/TR/2000/REC-DOM-Level-2-Events-20001113/events.html#Event…">OnUnload
+ event binding</ulink> in the HTML DOM was a <emphasis>CRIME</emphasis>.
+ When I close a browser window, I want it to close and die. Basta.
+ This job replaces the <quote>onunload</quote> attribute in
+ <quote><body></quote> tags with the dummy word <literal>never</literal>.
+ Note that the <literal>i</literal> option makes the pattern matching
+ case-insensitive. Also note that ungreedy matching alone doesn't always guarantee
+ a minimal match: In the first parenthesis, we had to use <literal>[^>]*</literal>
+ instead of <literal>.*</literal> to prevent the match from exceeding the
+ <body> tag if it doesn't contain <quote>OnUnload</quote>, but the page's
+ content does.
+</para>
+
+<para>
+ The last example is from the fun department:
+</para>
+
+<para>
+ <screen>
+FILTER: fun Fun text replacements
+
+# Spice the daily news:
+#
+s/microsoft(?!\.com)/MicroSuck/ig</screen>
+</para>
+
+<para>
+ Note the <literal>(?!\.com)</literal> part (a so-called negative lookahead)
+ in the job's pattern, which means: Don't match, if the string
+ <quote>.com</quote> appears directly following <quote>microsoft</quote>
+ in the page. This prevents links to microsoft.com from being trashed, while
+ still replacing the word everywhere else.

+ in the comments at the start of each file. Note that these comments are not
+ always accurate, and that it's probably best to look at the existing HTML
+ code to find out which symbols are supported and what they are filled in with.
+</para>
+
+<para>
+ A special application of this substitution mechanism is to make whole
+ blocks of HTML code disappear when a specific symbol is set. We use this
+ for many purposes, one of them being to include the beta warning in all
+ our user interface (CGI) pages when <application>Privoxy</application>
+ is in an alpha or beta development stage:
+</para>
+
+<para>
+ <screen>
+<!-- @if-unstable-start -->
+
+ ... beta warning HTML code goes here ...
+
+<!-- if-unstable-end@ --></screen>
+</para>
+
+<para>
+ If the "unstable" symbol is set, everything in between and including
+ <literal>@if-unstable-start</literal> and <literal>if-unstable-end@</literal>
+ will disappear, leaving nothing but an empty comment:
+</para>
+
+<para>
+ <screen><!-- --></screen>
+</para>
+
+<para>
+ There's also an if-then-else construct and an <literal>#include</literal>
+ mechanism, but you'll sure find out if you are inclined to edit the
+ templates ;-)
+</para>
+
+<para>
+ All templates refer to a style located at
+ <ulink url="http://config.privoxy.org/send-stylesheet"><literal>http://config.privoxy.org/send-stylesheet</literal></ulink>.
+ This is, of course, locally served by <application>Privoxy</application>

+ If you are reading this, you probably don't understand what <quote>regular
+ expressions</quote> are, or what they can do. So this will be a very brief
+ introduction only. A full explanation would require a <ulink
+ url="http://www.oreilly.com/catalog/regex/">book</ulink> ;-)
+</para>
+
+<para>
+ Regular expressions provide a language to describe patterns that can be
+ run against strings of characters (letter, numbers, etc), to see if they
+ match the string or not. The patterns are themselves (sometimes complex)
+ strings of literal characters, combined with wild-cards, and other special
+ characters, called meta-characters. The <quote>meta-characters</quote> have
+ special meanings and are used to build complex patterns to be matched against.
+ Perl Compatible Regular Expressions are an especially convenient
+ <quote>dialect</quote> of the regular expression language.
+</para>
+
+<para>
+ To make a simple analogy, we do something similar when we use wild-card
+ characters when listing files with the <command>dir</command> command in DOS.
+ <literal>*.*</literal> matches all filenames. The <quote>special</quote>
+ character here is the asterisk which matches any and all characters. We can be
+ more specific and use <literal>?</literal> to match just individual
+ characters. So <quote>dir file?.text</quote> would match
+ <quote>file1.txt</quote>, <quote>file2.txt</quote>, etc. We are pattern
+ matching, using a similar technique to <quote>regular expressions</quote>!
+</para>
+
+<para>
+ Regular expressions do essentially the same thing, but are much, much more
+ powerful. There are many more <quote>special characters</quote> and ways of
+ building complex patterns however. Let's look at a few of the common ones,
+ and then some examples:
+</para>
+
+<para><simplelist>
+ <member>
+ <emphasis>.</emphasis> - Matches any single character, e.g. <quote>a</quote>,
+ <quote>A</quote>, <quote>4</quote>, <quote>:</quote>, or <quote>@</quote>.
+ </member>
+</simplelist></para>
+
+<para><simplelist>
+ <member>
+ <emphasis>?</emphasis> - The preceding character or expression is matched ZERO or ONE
+ times. Either/or.
+ </member>
+</simplelist></para>
+
+<para><simplelist>
+ <member>
+ <emphasis>+</emphasis> - The preceding character or expression is matched ONE or MORE
+ times.
+ </member>
+</simplelist></para>
+
+<para><simplelist>
+ <member>
+ <emphasis>*</emphasis> - The preceding character or expression is matched ZERO or MORE
+ times.
+ </member>
+</simplelist></para>
+
+<para><simplelist>
+ <member>
+ <emphasis>\</emphasis> - The <quote>escape</quote> character denotes that
+ the following character should be taken literally. This is used where one of the
+ special characters (e.g. <quote>.</quote>) needs to be taken literally and
+ not as a special meta-character. Example: <quote>example\.com</quote>, makes
+ sure the period is recognized only as a period (and not expanded to its
+ meta-character meaning of any single character).
+ </member>
+</simplelist></para>
+
+<para><simplelist>
+ <member>
+ <emphasis>[ ]</emphasis> - Characters enclosed in brackets will be matched if
+ any of the enclosed characters are encountered. For instance, <quote>[0-9]</quote>
+ matches any numeric digit (zero through nine). As an example, we can combine
+ this with <quote>+</quote> to match any digit one of more times: <quote>[0-9]+</quote>.
+ </member>
+</simplelist></para>
+
+<para><simplelist>
+ <member>
+ <emphasis>( )</emphasis> - parentheses are used to group a sub-expression,
+ or multiple sub-expressions.
+ </member>
+</simplelist></para>
+
+<para><simplelist>
+ <member>
+ <emphasis>|</emphasis> - The <quote>bar</quote> character works like an
+ <quote>or</quote> conditional statement. A match is successful if the
+ sub-expression on either side of <quote>|</quote> matches. As an example:
+ <quote>/(this|that) example/</quote> uses grouping and the bar character
+ and would match either <quote>this example</quote> or <quote>that
+ example</quote>, and nothing else.
+ </member>
+</simplelist></para>
+
+<para>
+ These are just some of the ones you are likely to use when matching URLs with
+ <application>Privoxy</application>, and is a long way from a definitive
+ list. This is enough to get us started with a few simple examples which may
+ be more illuminating:
+</para>
+
+<para>
+ <emphasis><literal>/.*/banners/.*</literal></emphasis> - A simple example
+ that uses the common combination of <quote>.</quote> and <quote>*</quote> to
+ denote any character, zero or more times. In other words, any string at all.
+ So we start with a literal forward slash, then our regular expression pattern
+ (<quote>.*</quote>) another literal forward slash, the string
+ <quote>banners</quote>, another forward slash, and lastly another
+ <quote>.*</quote>. We are building
+ a directory path here. This will match any file with the path that has a
+ directory named <quote>banners</quote> in it. The <quote>.*</quote> matches
+ any characters, and this could conceivably be more forward slashes, so it
+ might expand into a much longer looking path. For example, this could match:
+ <quote>/eye/hate/spammers/banners/annoy_me_please.gif</quote>, or just
+ <quote>/banners/annoying.html</quote>, or almost an infinite number of other
+ possible combinations, just so it has <quote>banners</quote> in the path
+ somewhere.
+</para>
+
+<para>
+ And now something a little more complex:
+</para>
+
+<para>
+ <emphasis><literal>/.*/adv((er)?ts?|ertis(ing|ements?))?/</literal></emphasis> -
+ We have several literal forward slashes again (<quote>/</quote>), so we are
+ building another expression that is a file path statement. We have another
+ <quote>.*</quote>, so we are matching against any conceivable sub-path, just so
+ it matches our expression. The only true literal that <emphasis>must
+ match</emphasis> our pattern is <application>adv</application>, together with
+ the forward slashes. What comes after the <quote>adv</quote> string is the
+ interesting part.
+</para>
+
+<para>
+ Remember the <quote>?</quote> means the preceding expression (either a
+ literal character or anything grouped with <quote>(...)</quote> in this case)
+ can exist or not, since this means either zero or one match. So
+ <quote>((er)?ts?|ertis(ing|ements?))</quote> is optional, as are the
+ individual sub-expressions: <quote>(er)</quote>,
+ <quote>(ing|ements?)</quote>, and the <quote>s</quote>. The <quote>|</quote>
+ means <quote>or</quote>. We have two of those. For instance,
+ <quote>(ing|ements?)</quote>, can expand to match either <quote>ing</quote>
+ <emphasis>OR</emphasis> <quote>ements?</quote>. What is being done here, is an
+ attempt at matching as many variations of <quote>advertisement</quote>, and
+ similar, as possible. So this would expand to match just <quote>adv</quote>,
+ or <quote>advert</quote>, or <quote>adverts</quote>, or
+ <quote>advertising</quote>, or <quote>advertisement</quote>, or
+ <quote>advertisements</quote>. You get the idea. But it would not match
+ <quote>advertizements</quote> (with a <quote>z</quote>). We could fix that by
+ changing our regular expression to:
+ <quote>/.*/adv((er)?ts?|erti(s|z)(ing|ements?))?/</quote>, which would then match
+ either spelling.
+</para>
+
+<para>
+ <emphasis><literal>/.*/advert[0-9]+\.(gif|jpe?g)</literal></emphasis> - Again
+ another path statement with forward slashes. Anything in the square brackets
+ <quote>[ ]</quote> can be matched. This is using <quote>0-9</quote> as a
+ shorthand expression to mean any digit one through nine. It is the same as
+ saying <quote>0123456789</quote>. So any digit matches. The <quote>+</quote>
+ means one or more of the preceding expression must be included. The preceding
+ expression here is what is in the square brackets -- in this case, any digit
+ one through nine. Then, at the end, we have a grouping: <quote>(gif|jpe?g)</quote>.
+ This includes a <quote>|</quote>, so this needs to match the expression on
+ either side of that bar character also. A simple <quote>gif</quote> on one side, and the other
+ side will in turn match either <quote>jpeg</quote> or <quote>jpg</quote>,
+ since the <quote>?</quote> means the letter <quote>e</quote> is optional and
+ can be matched once or not at all. So we are building an expression here to
+ match image GIF or JPEG type image file. It must include the literal
+ string <quote>advert</quote>, then one or more digits, and a <quote>.</quote>
+ (which is now a literal, and not a special character, since it is escaped
+ with <quote>\</quote>), and lastly either <quote>gif</quote>, or
+ <quote>jpeg</quote>, or <quote>jpg</quote>. Some possible matches would
+ include: <quote>//advert1.jpg</quote>,
+ <quote>/nasty/ads/advert1234.gif</quote>,
+ <quote>/banners/from/hell/advert99.jpg</quote>. It would not match
+ <quote>advert1.gif</quote> (no leading slash), or
+ <quote>/adverts232.jpg</quote> (the expression does not include an
+ <quote>s</quote>), or <quote>/advert1.jsp</quote> (<quote>jsp</quote> is not
+ in the expression anywhere).
+</para>
+
+<para>
+ We are barely scratching the surface of regular expressions here so that you
+ can understand the default <application>Privoxy</application>
+ configuration files, and maybe use this knowledge to customize your own
+ installation. There is much, much more that can be done with regular
+ expressions. Now that you know enough to get started, you can learn more on

+<title>Chain of Events</title>
+<para>
+ Let's take a quick look at how some of <application>Privoxy's</application>
+ core features are triggered, and the ensuing sequence of events when a web
+ page is requested by your browser:
+</para>
+
+<para>
+ <itemizedlist>
+ <listitem>
+ <para>
+ First, your web browser requests a web page. The browser knows to send
+ the request to <application>Privoxy</application>, which will in turn,
+ relay the request to the remote web server after passing the following
+ tests:
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ <application>Privoxy</application> traps any request for its own internal CGI
+ pages (e.g <ulink url="http://p.p/">http://p.p/</ulink>) and sends the CGI page back to the browser.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Next, <application>Privoxy</application> checks to see if the URL
+ matches any <link
+ linkend="BLOCK"><quote>+block</quote></link> patterns. If
+ so, the URL is then blocked, and the remote web server will not be contacted.
+ <link linkend="HANDLE-AS-IMAGE"><quote>+handle-as-image</quote></link>
+ and
+ <link linkend="HANDLE-AS-EMPTY-DOCUMENT"><quote>+handle-as-empty-document</quote></link>
+ are then checked, and if there is no match, an
+ HTML <quote>BLOCKED</quote> page is sent back to the browser. Otherwise, if
+ it does match, an image is returned for the former, and an empty text
+ document for the latter. The type of image would depend on the setting of
+ <link linkend="SET-IMAGE-BLOCKER"><quote>+set-image-blocker</quote></link>
+ (blank, checkerboard pattern, or an HTTP redirect to an image elsewhere).
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Untrusted URLs are blocked. If URLs are being added to the
+ <filename>trust</filename> file, then that is done.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ If the URL pattern matches the <link
+ linkend="FAST-REDIRECTS"><quote>+fast-redirects</quote></link> action,
+ it is then processed. Unwanted parts of the requested URL are stripped.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Now the rest of the client browser's request headers are processed. If any
+ of these match any of the relevant actions (e.g. <link
+ linkend="HIDE-USER-AGENT"><quote>+hide-user-agent</quote></link>,
+ etc.), headers are suppressed or forged as determined by these actions and
+ their parameters.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Now the web server starts sending its response back (i.e. typically a web
+ page).
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ First, the server headers are read and processed to determine, among other
+ things, the MIME type (document type) and encoding. The headers are then
+ filtered as determined by the
+ <link linkend="CRUNCH-INCOMING-COOKIES"><quote>+crunch-incoming-cookies</quote></link>,
+ <link linkend="SESSION-COOKIES-ONLY"><quote>+session-cookies-only</quote></link>,
+ and <link linkend="DOWNGRADE-HTTP-VERSION"><quote>+downgrade-http-version</quote></link>
+ actions.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ If any <link linkend="FILTER"><quote>+filter</quote></link> action
+ or <link
+ linkend="DEANIMATE-GIFS"><quote>+deanimate-gifs</quote></link>
+ action applies (and the document type fits the action), the rest of the page is
+ read into memory (up to a configurable limit). Then the filter rules (from
+ <filename>default.filter</filename> and any other filter files) are
+ processed against the buffered content. Filters are applied in the order
+ they are specified in one of the filter files. Animated GIFs, if present,
+ are reduced to either the first or last frame, depending on the action
+ setting.The entire page, which is now filtered, is then sent by
+ <application>Privoxy</application> back to your browser.
+ </para>
+ <para>
+ If neither a <link linkend="FILTER"><quote>+filter</quote></link> action
+ or <link
+ linkend="DEANIMATE-GIFS"><quote>+deanimate-gifs</quote></link>
+ matches, then <application>Privoxy</application> passes the raw data through
+ to the client browser as it becomes available.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ As the browser receives the now (possibly filtered) page content, it
+ reads and then requests any URLs that may be embedded within the page
+ source, e.g. ad images, stylesheets, JavaScript, other HTML documents (e.g.
+ frames), sounds, etc. For each of these objects, the browser issues a
+ separate request (this is easily viewable in <application>Privoxy's</application>
+ logs). And each such request is in turn processed just as above. Note that a
+ complex web page will have many, many such embedded URLs. If these
+ secondary requests are to a different server, then quite possibly a very
+ differing set of actions is triggered.
+ </para>

+<title>Troubleshooting: Anatomy of an Action</title>
+
+<para>
+ The way <application>Privoxy</application> applies
+ <link linkend="ACTIONS">actions</link> and <link linkend="FILTER">filters</link>
+ to any given URL can be complex, and not always so
+ easy to understand what is happening. And sometimes we need to be able to
+ <emphasis>see</emphasis> just what <application>Privoxy</application> is
+ doing. Especially, if something <application>Privoxy</application> is doing
+ is causing us a problem inadvertently. It can be a little daunting to look at
+ the actions and filters files themselves, since they tend to be filled with
+ <link linkend="regex">regular expressions</link> whose consequences are not
+ always so obvious.
+</para>
+
+<para>
+ One quick test to see if <application>Privoxy</application> is causing a problem
+ or not, is to disable it temporarily. This should be the first troubleshooting
+ step. See <link linkend="bookmarklets">the Bookmarklets</link> section on a quick
+ and easy way to do this (be sure to flush caches afterward!). Looking at the
+ logs is a good idea too. (Note that both the toggle feature and logging are
+ enabled via <filename>config</filename> file settings, and may need to be
+ turned <quote>on</quote>.)
+</para>
+<para>
+ Another easy troubleshooting step to try is if you have done any
+ customization of your installation, revert back to the installed
+ defaults and see if that helps. There are times the developers get complaints
+ about one thing or another, and the problem is more related to a customized
+ configuration issue.
+</para>
+
+<para>
+ <application>Privoxy</application> also provides the
+ <ulink url="http://config.privoxy.org/show-url-info">http://config.privoxy.org/show-url-info</ulink>
+ page that can show us very specifically how <application>actions</application>
+ are being applied to any given URL. This is a big help for troubleshooting.
+</para>
+
+<para>
+ First, enter one URL (or partial URL) at the prompt, and then
+ <application>Privoxy</application> will tell us
+ how the current configuration will handle it. This will not
+ help with filtering effects (i.e. the <link
+ linkend="FILTER"><quote>+filter</quote></link> action) from
+ one of the filter files since this is handled very
+ differently and not so easy to trap! It also will not tell you about any other
+ URLs that may be embedded within the URL you are testing. For instance, images
+ such as ads are expressed as URLs within the raw page source of HTML pages. So
+ you will only get info for the actual URL that is pasted into the prompt area
+ -- not any sub-URLs. If you want to know about embedded URLs like ads, you
+ will have to dig those out of the HTML source. Use your browser's <quote>View
+ Page Source</quote> option for this. Or right click on the ad, and grab the
+ URL.
+</para>
+
+<para>
+ Let's try an example, <ulink url="http://google.com">google.com</ulink>,
+ and look at it one section at a time in a sample configuration (your real
+ configuration may vary):
+</para>
+
+<para>
+ <screen>
+ Matches for http://www.google.com:
+
+ In file: default.action <guibutton>[ View ]</guibutton> <guibutton>[ Edit ]</guibutton>
+
+ {+change-x-forwarded-for{block}
+ +deanimate-gifs {last}
+ +fast-redirects {check-decoded-url}
+ +filter {refresh-tags}
+ +filter {img-reorder}
+ +filter {banners-by-size}
+ +filter {webbugs}
+ +filter {jumping-windows}
+ +filter {ie-exploits}
+ +hide-from-header {block}
+ +hide-referrer {forge}
+ +session-cookies-only
+ +set-image-blocker {pattern}

+
+ { -session-cookies-only }
+ .google.com
+
+ { -fast-redirects }
+ .google.com
+
+In file: user.action <guibutton>[ View ]</guibutton> <guibutton>[ Edit ]</guibutton>
+(no matches in this file)
+</screen>
+</para>
+
+<para>
+ This is telling us how we have defined our
+ <link linkend="ACTIONS"><quote>actions</quote></link>, and
+ which ones match for our test case, <quote>google.com</quote>.
+ Displayed is all the actions that are available to us. Remember,
+ the <literal>+</literal> sign denotes <quote>on</quote>. <literal>-</literal>
+ denotes <quote>off</quote>. So some are <quote>on</quote> here, but many
+ are <quote>off</quote>. Each example we try may provide a slightly different
+ end result, depending on our configuration directives.
+</para>
+<para>
+ The first listing
+ is for our <filename>default.action</filename> file. The large, multi-line
+ listing, is how the actions are set to match for all URLs, i.e. our default
+ settings. If you look at your <quote>actions</quote> file, this would be the
+ section just below the <quote>aliases</quote> section near the top. This
+ will apply to all URLs as signified by the single forward slash at the end
+ of the listing -- <quote> / </quote>.
+</para>
+
+<para>
+ But we have defined additional actions that would be exceptions to these general
+ rules, and then we list specific URLs (or patterns) that these exceptions
+ would apply to. Last match wins. Just below this then are two explicit
+ matches for <quote>.google.com</quote>. The first is negating our previous
+ cookie setting, which was for <link
+ linkend="SESSION-COOKIES-ONLY"><quote>+session-cookies-only</quote></link>
+ (i.e. not persistent). So we will allow persistent cookies for google, at
+ least that is how it is in this example. The second turns
+ <emphasis>off</emphasis> any <link
+ linkend="FAST-REDIRECTS"><quote>+fast-redirects</quote></link>
+ action, allowing this to take place unmolested. Note that there is a leading
+ dot here -- <quote>.google.com</quote>. This will match any hosts and
+ sub-domains, in the google.com domain also, such as
+ <quote>www.google.com</quote> or <quote>mail.google.com</quote>. But it would not
+ match <quote>www.google.de</quote>! So, apparently, we have these two actions
+ defined as exceptions to the general rules at the top somewhere in the lower
+ part of our <filename>default.action</filename> file, and
+ <quote>google.com</quote> is referenced somewhere in these latter sections.
+</para>
+
+<para>
+ Then, for our <filename>user.action</filename> file, we again have no hits.
+ So there is nothing google-specific that we might have added to our own, local
+ configuration. If there was, those actions would over-rule any actions from
+ previously processed files, such as <filename>default.action</filename>.
+ <filename>user.action</filename> typically has the last word. This is the
+ best place to put hard and fast exceptions,
+</para>
+
+<para>
+ And finally we pull it all together in the bottom section and summarize how
+ <application>Privoxy</application> is applying all its <quote>actions</quote>
+ to <quote>google.com</quote>:
+
+</para>
+
+<para>

+ Notice the only difference here to the previous listing, is to
+ <quote>fast-redirects</quote> and <quote>session-cookies-only</quote>,
+ which are activated specifically for this site in our configuration,
+ and thus show in the <quote>Final Results</quote>.
+</para>
+
+<para>
+ Now another example, <quote>ad.doubleclick.net</quote>:
+</para>
+
+<para>
+ <screen>
+
+ { +block{Domains starts with "ad"} }
+ ad*.
+
+ { +block{Domain contains "ad"} }
+ .ad.
+
+ { +block{Doubleclick banner server} +handle-as-image }
+ .[a-vx-z]*.doubleclick.net
+</screen>
+</para>
+
+<para>
+ We'll just show the interesting part here - the explicit matches. It is
+ matched three different times. Two <quote>+block{}</quote> sections,
+ and a <quote>+block{} +handle-as-image</quote>,
+ which is the expanded form of one of our aliases that had been defined as:
+ <quote>+block-as-image</quote>. (<link
+ linkend="ALIASES"><quote>Aliases</quote></link> are defined in
+ the first section of the actions file and typically used to combine more
+ than one action.)
+</para>
+
+<para>
+ Any one of these would have done the trick and blocked this as an unwanted
+ image. This is unnecessarily redundant since the last case effectively
+ would also cover the first. No point in taking chances with these guys
+ though ;-) Note that if you want an ad or obnoxious
+ URL to be invisible, it should be defined as <quote>ad.doubleclick.net</quote>
+ is done here -- as both a <link
+ linkend="BLOCK"><quote>+block{}</quote></link>
+ <emphasis>and</emphasis> an
+ <link linkend="HANDLE-AS-IMAGE"><quote>+handle-as-image</quote></link>.
+ The custom alias <quote><literal>+block-as-image</literal></quote> just
+ simplifies the process and make it more readable.
+</para>
+
+<para>
+ One last example. Let's try <quote>http://www.example.net/adsl/HOWTO/</quote>.
+ This one is giving us problems. We are getting a blank page. Hmmm ...
+</para>
+
+<para>
+ <screen>

+ /
+
+ { +block{Path contains "ads".} +handle-as-image }
+ /ads
+</screen>
+</para>
+
+<para>
+ Ooops, the <quote>/adsl/</quote> is matching <quote>/ads</quote> in our
+ configuration! But we did not want this at all! Now we see why we get the
+ blank page. It is actually triggering two different actions here, and
+ the effects are aggregated so that the URL is blocked, and &my-app; is told
+ to treat the block as if it were an image. But this is, of course, all wrong.
+ We could now add a new action below this (or better in our own
+ <filename>user.action</filename> file) that explicitly
+ <emphasis>un</emphasis> blocks (
+ <link linkend="BLOCK"><quote>{-block}</quote></link>) paths with
+ <quote>adsl</quote> in them (remember, last match in the configuration
+ wins). There are various ways to handle such exceptions. Example:
+</para>
+
+<para>
+ <screen>
+
+ { -block }
+ /adsl
+</screen>
+</para>
+
+<para>
+ Now the page displays ;-)
+ Remember to flush your browser's caches when making these kinds of changes to
+ your configuration to insure that you get a freshly delivered page! Or, try
+ using <literal>Shift+Reload</literal>.
+</para>
+
+<para>
+ But now what about a situation where we get no explicit matches like
+ we did with:
+</para>
+
+<para>
+ <screen>
+
+ { +block{Path starts with "ads".} +handle-as-image }
+ /ads
+</screen>
+</para>
+
+<para>
+ That actually was very helpful and pointed us quickly to where the problem
+ was. If you don't get this kind of match, then it means one of the default
+ rules in the first section of <filename>default.action</filename> is causing
+ the problem. This would require some guesswork, and maybe a little trial and
+ error to isolate the offending rule. One likely cause would be one of the
+ <link linkend="FILTER"><quote>+filter</quote></link> actions.
+ These tend to be harder to troubleshoot.
+ Try adding the URL for the site to one of aliases that turn off
+ <link linkend="FILTER"><quote>+filter</quote></link>:
+</para>
+
+<para>
+ <screen>
+
+ { shop }
+ .quietpc.com
+ .worldpay.com # for quietpc.com
+ .jungle.com
+ .scan.co.uk
+ .forbes.com
+</screen>
+</para>
+
+<para>
+ <quote><literal>{ shop }</literal></quote> is an <quote>alias</quote> that expands to
+ <quote><literal>{ -filter -session-cookies-only }</literal></quote>.
+ Or you could do your own exception to negate filtering:
+
+</para>
+
+<para>
+ <screen>
+
+ { -filter }
+ # Disable ALL filter actions for sites in this section
+ .forbes.com
+ developer.ibm.com
+ localhost
+</screen>
+</para>
+
+<para>
+ This would turn off all filtering for these sites. This is best
+ put in <filename>user.action</filename>, for local site
+ exceptions. Note that when a simple domain pattern is used by itself (without
+ the subsequent path portion), all sub-pages within that domain are included
+ automatically in the scope of the action.
+</para>
+
+<para>
+ Images that are inexplicably being blocked, may well be hitting the
+<link linkend="FILTER-BANNERS-BY-SIZE"><quote>+filter{banners-by-size}</quote></link>
+ rule, which assumes
+ that images of certain sizes are ad banners (works well
+ <emphasis>most of the time</emphasis> since these tend to be standardized).
+</para>
+
+<para>
+ <quote><literal>{ fragile }</literal></quote> is an alias that disables most
+ actions that are the most likely to cause trouble. This can be used as a
+ last resort for problem sites.
+</para>
+<para>
+ <screen>
+
+ { fragile }
+ # Handle with care: easy to break
+ mail.google.
+ mybank.example.com</screen>
+</para>
+
+
+<para>
+ <emphasis>Remember to flush caches!</emphasis> Note that the
+ <literal>mail.google</literal> reference lacks the TLD portion (e.g.
+ <quote>.com</quote>). This will effectively match any TLD with
+ <literal>google</literal> in it, such as <literal>mail.google.de.</literal>,
+ just as an example.
+</para>
+<para>
+ If this still does not work, you will have to go through the remaining
+ actions one by one to find which one(s) is causing the problem.

+
+See http://www.privoxy.org/3.0.12/user-manual/whatsnew.html for details.
+
+--------------------------------------------------------------------
+ChangeLog for Privoxy
+--------------------------------------------------------------------
+*** Version 3.0.12 ***
+
+- The socket-timeout option now also works on platforms whose
+ select() implementation modifies the timeout structure.
+ Previously the timeout was triggered even if the connection
+ didn't stall. Reported by cyberpatrol.
+- The Connection: keep-alive code properly deals with files
+ larger than 2GB. Previously the connection was closed too
+ early.
+- The content length for files above 2GB is logged correctly.
+- The user-manual directive on the show-status page links to
+ the documentation location specified with the directive,
+ not to the Privoxy website.
+- When running in daemon mode, Privoxy doesn't log anything
+ to the console unless there are errors before the logfile
+ has been opened.
+- The show-status page prints warnings about invalid directives
+ on the same line as the directives themselves.
+- Fixed several justified (but harmless) compiler warnings,
+ mostly on 64 bit platforms.
+- The mingw32 version explicitly requests the default charset
+ to prevent display problems with some fonts available on more
+ recent Windows versions. Patch by Burberry.
+- The mingw32 version uses the Privoxy icon in the alt-tab
+ windows. Patch by Burberry.
+- The timestamp and the thread id is omitted in the "Fatal error"
+ message box on mingw32.
+- Fixed two related mingw32-only buffer overflows. Triggering
+ them required control over the configuration file, therefore
+ this isn't seen as a security issue.
+- In verbose mode, or if the new option --show-skipped-tests
+ is used, Privoxy-Regression-Test logs skipped tests and the
+ skip reason.
+

+About Privoxy:
+-----------------------------------------------------------------
+
+Privoxy is a non-caching web proxy with advanced filtering capabilities for
+enhancing privacy, modifying web page data and HTTP headers, controlling
+access, and removing ads and other obnoxious Internet junk. Privoxy has a
+flexible configuration and can be customized to suit individual needs and
+tastes. It has application for both stand-alone systems and multi-user
+networks.
+
+Privoxy is Free Software and licensed under the GPL2.
+
+Privoxy is an associated project of Software in the Public Interest (SPI).
+Donations are welcome: http://www.privoxy.org/faq/general.html#DONATE
+
+At present, Privoxy is known to run on Windows(95, 98, ME, 2000,
+XP, Vista), Linux (Ubuntu, RedHat, SuSE, Debian, Fedora, Gentoo and
+others), Mac OSX, OS/2, AmigaOS, FreeBSD, NetBSD, OpenBSD, Solaris, and
+various other flavors of Unix.
+
+In addition to the core features of ad blocking and cookie management,
+Privoxy provides many supplemental features, that give the end-user
+more control, more privacy and more freedom:
+
+
+ * Can keep outgoing connections alive and reuse them later on.
+
+ * Supports tagging which allows to change the behaviour based on client
+ and server headers.
+
+ * Can be run as an "intercepting" proxy, which obviates the need to
+ configure browsers individually.
+
+ * Sophisticated actions and filters for manipulating both server and
+ client headers.
+
+ * Can be chained with other proxies.
+
+ * Integrated browser based configuration and control utility at
+ http://config.privoxy.org/ (shortcut: http://p.p/) Browser-based
+ tracing of rule and filter effects. Remote toggling.
+
+ * Web page filtering (text replacements, removes banners based on size,
+ invisible "web-bugs", JavaScript and HTML annoyances, pop-up windows,
+ etc.)
+
+ * Modularized configuration that allows for standard settings and user
+ settings to reside in separate files, so that installing updated actions
+ files won't overwrite individual user settings.
+
+ * Support for Perl Compatible Regular Expressions in the configuration
+ files, and a more sophisticated and flexible configuration syntax.
+
+ * Improved cookie management features (e.g. session based cookies).
+
+ * GIF de-animation.
+
+ * Bypass many click-tracking scripts (avoids script redirection).
+
+ * Multi-threaded (POSIX and native threads).
+
+ * User-customizable HTML templates for most proxy-generated pages (e.g.
+ "blocked" page).
+
+ * Auto-detection and re-reading of config file changes.
+
+ * Improved signal handling, and a true daemon mode (Unix).
+
+ * Every feature now controllable on a per-site or per-location basis,
+ configuration more powerful and versatile over-all.

+ <A
+HREF="http://www.junkbusters.com/ijb.html"
+TARGET="_top"
+><SPAN
+CLASS="APPLICATION"
+>Internet Junkbuster</SPAN
+></A
+>,
+ by Anonymous Coders and <A
+HREF="http://www.junkbusters.com/"
+TARGET="_top"
+>Junkbusters
+ Corporation</A
+>. This saved many users a lot of pain in the early days of
+ web advertising and user tracking.</P
+><P
+> But the web, its protocols and standards, and with it, the techniques for
+ forcing ads on users, give up autonomy over their browsing, and
+ for tracking them, keeps evolving. Unfortunately, the <SPAN
+CLASS="APPLICATION"
+>Internet
+ Junkbuster</SPAN
+> did not. Version 2.0.2, published in 1998, was
+ (and is) the last official
+ <A
+HREF="http://www.junkbusters.com/ijbdist.html#release"
+TARGET="_top"
+>release</A
+>
+ available from <A
+HREF="http://www.junkbusters.com"
+TARGET="_top"
+>Junkbusters Corporation</A
+>.
+ Fortunately, it had been released under the GNU
+ <A
+HREF="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
+TARGET="_top"
+>GPL</A
+>,
+ which allowed further development by others.</P
+><P
+> So Stefan Waldherr started maintaining an improved version of the
+ software, to which eventually a number of people contributed patches.
+ It could already replace banners with a transparent image, and had a first
+ version of pop-up killing, but it was still very closely based on the
+ original, with all its limitations, such as the lack of HTTP/1.1 support,
+ flexible per-site configuration, or content modification. The last release
+ from this effort was version 2.0.2-10, published in 2000.</P
+><P
+> Then, some
+ <A
+HREF="http://www.privoxy.org/user-manual/copyright.html#AUTHORS"
+TARGET="_top"
+>developers</A
+>
+ picked up the thread, and started turning the software inside out, upside down,
+ and then reassembled it, adding many
+ <A
+HREF="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
+TARGET="_top"
+>new
+ features</A
+> along the way.</P
+><P
+> The result of this is <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>, whose first
+ stable version, 3.0, was released August, 2002.

+> All formal documents are maintained in Docbook SGML and located in the

+> directory. You will need
+ <A
+HREF="http://www.docbook.org"
+TARGET="_top"
+>Docbook</A
+>, the Docbook
+ DTD's and the Docbook modular stylesheets (or comparable alternatives),
+ and either <SPAN
+CLASS="APPLICATION"
+>jade</SPAN
+> or
+ <SPAN
+CLASS="APPLICATION"
+>openjade</SPAN
+> (recommended) installed in order to
+ build docs from source. Currently there is <A
+HREF="../user-manual/index.html"
+TARGET="_top"
+><I
+CLASS="CITETITLE"
+>user-manual</I
+></A
+>,
+ <A
+HREF="../faq/index.html"
+TARGET="_top"

+CLASS="CITETITLE"
+>FAQ</I
+></A
+>, and, of
+ course this, the <I
+CLASS="CITETITLE"
+>developer-manual</I
+> in this format.
+ The <I
+CLASS="CITETITLE"
+>README</I
+>, <I
+CLASS="CITETITLE"
+>AUTHORS</I
+>,
+ <I
+CLASS="CITETITLE"
+>INSTALL</I

+ <I
+CLASS="CITETITLE"
+>privoxy.1</I
+> (man page), and
+ <I
+CLASS="CITETITLE"
+>config</I
+> files are also now maintained as Docbook
+ SGML. These files, when built, in the top-level source directory are
+ generated files! Also, the <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> <TT
+CLASS="FILENAME"
+>index.html</TT
+> (and a
+ variation on this file, <TT
+CLASS="FILENAME"
+>privoxy-index.html</TT
+>,
+ meant for inclusion with doc packages), are maintained as SGML as well.
+ <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>DO NOT edit these directly</I
+></SPAN
+>. Edit the SGML source, or
+ contact someone involved in the documentation.
+ </P
+><P
+> <TT
+CLASS="FILENAME"
+>config</TT
+> requires some special handling. The reason it
+ is maintained this way is so that the extensive comments in the file
+ mirror those in <I
+CLASS="CITETITLE"
+>user-manual</I
+>. But the conversion
+ process requires going from SGML to HTML to text to special formatting
+ required for the embedded comments. Some of this does not survive so
+ well. Especially some of the examples that are longer than 80 characters.
+ The build process for this file outputs to <TT
+CLASS="FILENAME"
+>config.new</TT
+>,
+ which should be reviewed for errors and mis-formatting. Once satisfied
+ that it is correct, then it should be hand copied to
+ <TT
+CLASS="FILENAME"
+>config</TT
+>.
+ </P
+><P
+> Other, less formal documents (e.g. <TT
+CLASS="FILENAME"
+>LICENSE</TT
+>) are
+ maintained as plain text files in the top-level source directory.
+ </P
+><P
+> Packagers are encouraged to include this documentation. For those without
+ the ability to build the docs locally, text versions of each are kept in
+ CVS. HTML versions are also being kept in CVS under
+ <TT
+CLASS="FILENAME"
+>doc/webserver/*</TT
+>. And PDF version are kept in
+ <TT
+CLASS="FILENAME"
+>doc/pdf/*</TT
+>.
+ </P
+><P
+> Formal documents are built with the Makefile targets of
+ <SAMP
+CLASS="COMPUTEROUTPUT"
+>make dok</SAMP
+>, or alternately
+ <SAMP
+CLASS="COMPUTEROUTPUT"
+>make redhat-dok</SAMP
+>. If you have problems,
+ try both. The build process uses the document SGML sources in
+ <SAMP
+CLASS="COMPUTEROUTPUT"
+>doc/source/*/*</SAMP
+> to update all text files in
+ <SAMP
+CLASS="COMPUTEROUTPUT"
+>doc/text/</SAMP
+> and to update all HTML
+ documents in <SAMP
+CLASS="COMPUTEROUTPUT"
+>doc/webserver/</SAMP
+>.
+ </P
+><P
+> Documentation writers should please make sure documents build
+ successfully before committing to CVS, if possible.

+> How do you update the webserver (i.e. the pages on privoxy.org)?
+
+ <P
+></P
+><OL
+TYPE="1"
+><LI
+><P
+> First, build the docs by running <SAMP
+CLASS="COMPUTEROUTPUT"
+>make
+ dok</SAMP

+>3.1. Quickstart to Docbook and SGML</A
+></H2
+><P
+> If you are not familiar with SGML, it is a markup language similar to HTML.
+ Actually, not a mark up language per se, but a language used to define
+ markup languages. In fact, HTML is an SGML application. Both will use
+ <SPAN
+CLASS="QUOTE"
+>"tags"</SPAN
+> to format text and other content. SGML tags can be much
+ more varied, and flexible, but do much of the same kinds of things. The tags,
+ or <SPAN
+CLASS="QUOTE"
+>"elements"</SPAN
+>, are definable in SGML. There is no set
+ <SPAN
+CLASS="QUOTE"
+>"standards"</SPAN
+>. Since we are using
+ <SPAN
+CLASS="APPLICATION"
+>Docbook</SPAN
+>, our tags are those that are defined by
+ <SPAN
+CLASS="APPLICATION"
+>Docbook</SPAN
+>. Much of how the finish document is
+ rendered is determined by the <SPAN
+CLASS="QUOTE"
+>"stylesheets"</SPAN
+>.
+ The stylesheets determine how each tag gets translated to HTML, or other
+ formats.</P
+><P
+> Tags in Docbook SGML need to be always <SPAN
+CLASS="QUOTE"
+>"closed"</SPAN
+>. If not, you
+ will likely generate errors. Example: <TT
+CLASS="LITERAL"
+><title>My
+ Title</title></TT
+>. They are also case-insensitive, but we
+ strongly suggest using all lower case. This keeps compatibility with
+ [Docbook] <SPAN
+CLASS="APPLICATION"
+>XML</SPAN
+>.</P
+><P
+> Our documents use <SPAN
+CLASS="QUOTE"
+>"sections"</SPAN
+> for the most part. Sections
+ will be processed into HTML headers (e.g. <TT
+CLASS="LITERAL"
+>h1</TT
+> for
+ <TT
+CLASS="LITERAL"
+>sect1</TT
+>). The <SPAN
+CLASS="APPLICATION"
+>Docbook</SPAN
+> stylesheets
+ will use these to also generate the Table of Contents for each doc. Our
+ TOC's are set to a depth of three. Meaning <TT
+CLASS="LITERAL"
+>sect1</TT
+>,
+ <TT
+CLASS="LITERAL"
+>sect2</TT
+>, and <TT
+CLASS="LITERAL"
+>sect3</TT
+> will have TOC
+ entries, but <TT
+CLASS="LITERAL"
+>sect4</TT
+> will not. Each section requires
+ a <TT
+CLASS="LITERAL"
+><title></TT
+> element, and at least one
+ <TT
+CLASS="LITERAL"
+><para></TT
+>. There is a limit of five section
+ levels in Docbook, but generally three should be sufficient for our

+ You can submit your ideas, or even better patches. Patches are best

+> First you need to determine which version number the release will have.
+ <SPAN

+ separated by dots, like in X.Y.Z (e.g. 3.0.0), where:
+ <P
+></P
+><UL
+><LI
+><P
+> X, the version major, is rarely ever changed. It is increased by one if
+ turning a development branch into stable substantially changes the functionality,
+ user interface or configuration syntax. Majors 1 and 2 were
+ <SPAN
+CLASS="APPLICATION"
+>Junkbuster</SPAN
+>, and 3 will be the first stable
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> release.
+ </P
+></LI
+><LI
+><P
+> Y, the version minor, represents the branch within the major version.
+ At any point in time, there are two branches being maintained:
+ The stable branch, with an even minor, say, 2N, in which no functionality is
+ being added and only bug-fixes are made, and 2N+1, the development branch, in
+ which the further development of <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> takes
+ place.
+ This enables us to turn the code upside down and inside out, while at the same time
+ providing and maintaining a stable version.
+ The minor is reset to zero (and one) when the major is incremented. When a development
+ branch has matured to the point where it can be turned into stable, the old stable branch
+ 2N is given up (i.e. no longer maintained), the former development branch 2N+1 becomes the
+ new stable branch 2N+2, and a new development branch 2N+3 is opened.
+ </P
+></LI
+><LI
+><P
+> Z, the point or sub version, represents a release of the software within a branch.
+ It is therefore incremented immediately before each code freeze.
+ In development branches, only the even point versions correspond to actual releases,
+ while the odd ones denote the evolving state of the sources on CVS in between.
+ It follows that Z is odd on CVS in development branches most of the time. There, it gets
+ increased to an even number immediately before a code freeze, and is increased to an odd
+ number again immediately thereafter.
+ This ensures that builds from CVS snapshots are easily distinguished from released versions.
+ The point version is reset to zero when the minor changes.
+ </P
+><P
+> Stable branches work a little differently, since there should be
+ little to no development happening in such branches. Remember,
+ only bugfixes, which presumably should have had some testing
+ before being committed. Stable branches will then have their
+ version reported as <TT
+CLASS="LITERAL"
+>0.0.0</TT
+>, during that period
+ between releases when changes are being added. This is to denote
+ that this code is <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>not for release</I
+></SPAN
+>. Then
+ as the release nears, the version is bumped according: e.g.
+ <TT
+CLASS="LITERAL"
+>3.0.1 -> 0.0.0 -> 3.0.2</TT
+>.
+ </P
+></LI
+></UL
+>
+ </P
+><P
+> In summary, the main CVS trunk is the development branch where new
+ features are being worked on for the next stable series. This should
+ almost always be where the most activity takes place. There is always at
+ least one stable branch from the trunk, e.g now it is
+ <TT
+CLASS="LITERAL"
+>3.0</TT
+>, which is only used to release stable versions.
+ Once the initial *.0 release of the stable branch has been done, then as a
+ rule, only bugfixes that have had prior testing should be committed to
+ the stable branch. Once there are enough bugfixes to justify a new
+ release, the version of this branch is again incremented Example: 3.0.0
+ -> 3.0.1 -> 3.0.2, etc are all stable releases from within the stable
+ branch. 3.1.x is currently the main trunk, and where work on 3.2.x is
+ taking place. If any questions, please post to the devel list
+ <SPAN

+ </P
+><P
+> Developers should remember too that if they commit a bugfix to the stable
+ branch, this will more than likely require a separate submission to the

+ are working on both, then this would require at least two separate check
+ outs (i.e main trunk, <SPAN

+> A long time ago, there was the
+ <A
+HREF="http://www.junkbusters.com/ijb.html"
+TARGET="_top"
+><SPAN
+CLASS="APPLICATION"
+>Internet Junkbuster</SPAN
+></A
+>,
+ by Anonymous Coders and <A
+HREF="http://www.junkbusters.com/"
+TARGET="_top"
+>Junkbusters
+ Corporation</A
+>. This saved many users a lot of pain in the early days of
+ web advertising and user tracking.</P
+><P
+> But the web, its protocols and standards, and with it, the techniques for
+ forcing ads on users, give up autonomy over their browsing, and
+ for tracking them, keeps evolving. Unfortunately, the <SPAN
+CLASS="APPLICATION"
+>Internet
+ Junkbuster</SPAN
+> did not. Version 2.0.2, published in 1998, was
+ (and is) the last official
+ <A
+HREF="http://www.junkbusters.com/ijbdist.html#release"
+TARGET="_top"
+>release</A
+>
+ available from <A
+HREF="http://www.junkbusters.com"
+TARGET="_top"
+>Junkbusters Corporation</A
+>.
+ Fortunately, it had been released under the GNU
+ <A
+HREF="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
+TARGET="_top"
+>GPL</A
+>,
+ which allowed further development by others.</P
+><P
+> So Stefan Waldherr started maintaining an improved version of the
+ software, to which eventually a number of people contributed patches.
+ It could already replace banners with a transparent image, and had a first
+ version of pop-up killing, but it was still very closely based on the
+ original, with all its limitations, such as the lack of HTTP/1.1 support,
+ flexible per-site configuration, or content modification. The last release
+ from this effort was version 2.0.2-10, published in 2000.</P
+><P
+> Then, some
+ <A
+HREF="http://www.privoxy.org/user-manual/copyright.html#AUTHORS"
+TARGET="_top"
+>developers</A
+>
+ picked up the thread, and started turning the software inside out, upside down,
+ and then reassembled it, adding many
+ <A
+HREF="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
+TARGET="_top"
+>new
+ features</A
+> along the way.</P
+><P
+> The result of this is <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>, whose first
+ stable version, 3.0, was released August, 2002.

+> One of <SPAN

+ will be a big plus and will help you get the most out of <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN

+ A new installation just includes a very basic configuration. The user

+>,
+ by Anonymous Coders and <A

+TARGET="_top"
+>Junkbusters
+ Corporation</A
+>. This saved many users a lot of pain in the early days of
+ web advertising and user tracking.</P
+><P
+> But the web, its protocols and standards, and with it, the techniques for
+ forcing ads on users, give up autonomy over their browsing, and
+ for tracking them, keeps evolving. Unfortunately, the <SPAN
+CLASS="APPLICATION"
+>Internet
+ Junkbuster</SPAN

+ <A
+HREF="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
+TARGET="_top"
+>GPL</A
+>,
+ which allowed further development by others.</P
+><P
+> So Stefan Waldherr started maintaining an improved version of the
+ software, to which eventually a number of people contributed patches.
+ It could already replace banners with a transparent image, and had a first
+ version of pop-up killing, but it was still very closely based on the
+ original, with all its limitations, such as the lack of HTTP/1.1 support,
+ flexible per-site configuration, or content modification. The last release
+ from this effort was version 2.0.2-10, published in 2000.</P
+><P
+> Then, some
+ <A
+HREF="http://www.privoxy.org/user-manual/copyright.html#AUTHORS"

+>developers</A
+>
+ picked up the thread, and started turning the software inside out, upside down,

+NAME="WHATSANAD"
+>1.8. How does Privoxy know what is
+an ad, and what is not?</A
+></H3
+><P
+> <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>'s approach to blocking ads is twofold:</P
+><P
+> First, there are certain patterns in the <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>locations</I
+></SPAN
+> (URLs)
+ of banner images. This applies to both the path (you wouldn't guess how many
+ web sites serve their banners from a directory called <SPAN
+CLASS="QUOTE"
+>"banners"</SPAN
+>!)
+ and the host (blocking the big banner hosting services like doublecklick.net
+ already helps a lot). <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> takes advantage of this
+ fact by using <A
+HREF="../user-manual/actions-file.html#AF-PATTERNS"
+TARGET="_top"
+>URL
+ patterns</A
+> to sort out and block the requests for things that sound
+ like they would be ads or banners.</P
+><P
+> Second, banners tend to come in certain <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>sizes</I
+></SPAN
+>. But you
+ can't tell the size of an image by its URL without downloading it, and if you
+ do, it's too late to save bandwidth. Therefore, <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ also inspects the HTML sources of web pages while they are loaded, and replaces
+ references to images with standard banner sizes by dummy references, so that
+ your browser doesn't request them anymore in the first place.</P
+><P
+> Both of this involves a certain amount of guesswork and is, of course, freely
+ and readily configurable.</P

+><DIV

+></H3
+><P
+> Actually, it's a black art ;-) And yes, it is always possible to have a broad
+ rule accidentally block or change something by mistake. You will almost surely
+ run into such situations at some point. It is tricky writing rules to
+ cover every conceivable possibility, and not occasionally get false positives.</P
+><P
+> But this should not be a big concern since the
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> configuration is very flexible, and
+ includes tools to help identify these types of situations so they can be
+ addressed as needed, allowing you to customize your installation.

+></H3

+> That depends on your expectations.
+ The default installation should give you a good starting

+><I
+CLASS="EMPHASIS"
+>most</I
+></SPAN
+> ads and unwanted content,
+ but many of the more advanced features are off by default, and require

+>Privoxy</SPAN
+> (see the <A
+HREF="installation.html#FIRSTSTEP"
+>Installation section below</A
+>). </P
+><P

+ or ads not being blocked that you may not want to see. In these cases, you

+ </P
+><P
+> In addition, a proxy is good choice if you use multiple browsers, or

+> The most important reason is because you have access to

+>everything</I
+></SPAN
+>, and you can control everything. You can
+ check every line of every configuration file yourself. You can check every

+ and do read it. You can build the software from scratch, if you want,
+ so that you know the executable is clean, and that it is
+ <SPAN

+><I
+CLASS="EMPHASIS"
+>yours</I

+>2.1. Which browsers are supported by Privoxy?</A
+></H3
+><P
+> Any browser that can be configured to use a proxy, which
+ should be virtually all browsers, including
+ <SPAN
+CLASS="APPLICATION"
+>Firefox</SPAN
+>, <SPAN
+CLASS="APPLICATION"
+>Internet
+ Explorer</SPAN
+>, <SPAN
+CLASS="APPLICATION"
+>Opera</SPAN
+>, and
+ <SPAN
+CLASS="APPLICATION"
+>Safari</SPAN
+> among others.
+ Direct browser support is not an absolute requirement since
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> runs as a separate application and talks
+ to the browser in the standardized HTTP protocol, just like a web server
+ does.</P
+></DIV
+><DIV
+CLASS="SECT2"
+><H3
+CLASS="SECT2"
+><A
+NAME="WHICHOS"
+>2.2. Which operating systems are supported?</A
+></H3
+><P
+> At present, <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is known to run on
+ Windows(95, 98, ME, 2000, XP, Vista), GNU/Linux (RedHat, SuSE, Debian,
+ Fedora, Gentoo, Slackware and others), Mac OSX, OS/2, AmigaOS, FreeBSD,
+ NetBSD, OpenBSD, Solaris, and various other flavors of Unix.</P
+><P
+> But any operating system that runs TCP/IP, can conceivably take advantage of
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> in a networked situation where
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> would run as a server on a LAN gateway.
+ Then only the <SPAN
+CLASS="QUOTE"
+>"gateway"</SPAN
+> needs to be running one of the above
+ operating systems.</P
+><P
+> Source code is freely available, so porting to other operating systems
+ is always a possibility.</P

+>2.3. Can I use Privoxy with my email client?</A
+></H3
+><P
+> As long as there is some way to set a HTTP proxy for the client, then yes,
+ any application can be used, whether it is strictly speaking a
+ <SPAN
+CLASS="QUOTE"
+>"browser"</SPAN
+> or not. Though this may not be the best approach for
+ dealing with some of the common abuses of HTML in email. See <A
+HREF="configuration.html#OUTLOOK"
+>How can I configure <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ with <SPAN
+CLASS="APPLICATION"
+>Outlook</SPAN
+>?</A
+> below for more on
+ this. </P
+><P
+> Be aware that HTML email presents a number of unique security and privacy
+ related issues, that can require advanced skills to overcome. The developers
+ recommend using email clients that can be configured to convert HTML to plain
+ text for these reasons.</P

+><A
+NAME="FIRSTSTEP"
+>2.4. I just installed Privoxy. Is there anything
+special I have to do now?</A
+></H3
+><P
+> All browsers should be told to use <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ as a proxy by specifying the correct proxy address and port number
+ in the appropriate configuration area for the browser. It's possible
+ to combine <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> with a packet filter to intercept HTTP requests
+ even if the client isn't explicitly configured to use <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>,
+ but where possible, configuring the client is recommended. See
+ <A
+HREF="../user-manual/startup.html"
+TARGET="_top"
+>the User Manual for more
+ details</A
+>. You should also flush your browser's memory and disk
+ cache to get rid of any cached junk items, and remove any stored
+ <A
+HREF="http://en.wikipedia.org/wiki/Browser_cookie"
+TARGET="_top"
+>cookies</A
+>. </P
+></DIV
+><DIV
+CLASS="SECT2"
+><H3
+CLASS="SECT2"
+><A
+NAME="LOCALHOST"
+>2.5. What is the proxy address of Privoxy?</A
+></H3
+><P
+> If you set up the <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> to run on
+ the computer you browse from (rather than your ISP's server or some
+ networked computer on a LAN), the proxy will be on <TT
+CLASS="LITERAL"
+>127.0.0.1</TT
+>
+ (sometimes referred to as <SPAN
+CLASS="QUOTE"
+>"localhost"</SPAN
+>,
+ which is the special name used by every computer on the Internet to refer
+ to itself) and the port will be 8118 (unless you used the <A
+HREF="../user-manual/config.html#LISTEN-ADDRESS"
+TARGET="_top"
+>listen-address</A
+>
+ config option to tell <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> to run on
+ a different port).
+ </P
+><P
+> When configuring your browser's proxy settings you typically enter
+ the word <SPAN
+CLASS="QUOTE"
+>"localhost"</SPAN
+> or the IP address <SPAN
+CLASS="QUOTE"
+>"127.0.0.1"</SPAN
+>
+ in the boxes next to <SPAN
+CLASS="QUOTE"
+>"HTTP"</SPAN
+> and <SPAN
+CLASS="QUOTE"
+>"Secure"</SPAN
+> (HTTPS) and
+ then the number <SPAN
+CLASS="QUOTE"
+>"8118"</SPAN
+> for <SPAN
+CLASS="QUOTE"
+>"port"</SPAN
+>.
+ This tells your browser to send all web requests to <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ instead of directly to the Internet.
+ </P
+><P
+> <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> can also be used to proxy for
+ a Local Area Network. In this case, your would enter either the IP
+ address of the LAN host where <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ is running, or the equivalent hostname, e.g. <TT
+CLASS="LITERAL"
+>192.168.1.1</TT
+>.
+ Port assignment would be same as above. Note that
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> doesn't listen on any LAN interfaces by
+ default.
+ </P
+><P
+> <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> does not currently handle
+ any other protocols such as FTP, SMTP, IM, IRC, ICQ, etc.
+ </P
+></DIV
+><DIV
+CLASS="SECT2"
+><H3
+CLASS="SECT2"
+><A
+NAME="NOTHING"
+>2.6. I just installed Privoxy, and nothing is happening.
+All the ads are there. What's wrong?</A
+></H3
+><P
+> Did you configure your browser to use <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ as a proxy? It does not sound like it. See above. You might also try flushing
+ the browser's caches to force a full re-reading of pages. You can verify
+ that <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is running, and your browser
+ is correctly configured by entering the special URL:
+ <A
+HREF="http://p.p/"
+TARGET="_top"
+>http://p.p/</A
+>.
+
+ This should take you to a page titled <SPAN
+CLASS="QUOTE"
+>"This is Privoxy.."</SPAN
+> with
+ access to <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+> internal configuration.
+ If you see this, then you are good to go. If you receive a page saying
+ <SPAN
+CLASS="QUOTE"
+>"Privoxy is not running"</SPAN
+>, then the browser is not set up to use
+ your <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> installation.
+ If you receive anything else (probably nothing at all), it could either
+ be that the browser is not set up correctly, or that
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is not running at all. Check the <A
+HREF="../user-manual/config.html#LOGFILE"
+TARGET="_top"
+>log file</A
+>. For instructions
+ on starting <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> and browser configuration,
+ see the <A
+HREF="http://www.privoxy.org/user-manual/startup.html"
+TARGET="_top"
+>chapter
+ on starting <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+></A
+> in the
+ <A
+HREF="http://www.privoxy.org/user-manual/"
+TARGET="_top"
+>User Manual</A
+>.</P
+></DIV
+><DIV
+CLASS="SECT2"
+><H3
+CLASS="SECT2"
+><A
+NAME="NOTUSED"
+>2.7. I get a <SPAN
+CLASS="QUOTE"
+>"Privoxy is not being used"</SPAN
+> dummy page although
+Privoxy is running and being used.</A
+></H3
+><P
+> First, make sure that Privoxy is <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>really</I
+></SPAN
+> running and
+ being used by visiting <A
+HREF="http://p.p/"
+TARGET="_top"
+>http://p.p/</A
+>. You
+ should see the <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> main page. If not, see
+ the <A
+HREF="http://www.privoxy.org/user-manual/startup.html"
+TARGET="_top"
+>chapter
+ on starting <SPAN

+>Privoxy</SPAN
+></A
+> in the
+ <A
+HREF="http://www.privoxy.org/user-manual/"
+TARGET="_top"
+>User Manual</A
+>.</P
+><P
+> Now if <A
+HREF="http://p.p/"
+TARGET="_top"
+>http://p.p/</A
+> works for you, but
+ other parts of <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>'s web interface show
+ the dummy page, your browser has cached a redirection it encountered before
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> was being used. You need to clear your
+ browser's cache. Note that shift-reloading the dummy page won't help, since
+ that'll only refresh the dummy page, not the redirection that lead you there.</P
+><P
+> The procedure for clearing the cache varies from browser to browser. For
+ example, <SPAN
+CLASS="APPLICATION"
+>Mozilla/Netscape</SPAN
+> users would click
+ <SPAN
+CLASS="GUIBUTTON"
+>Edit</SPAN
+> --> <SPAN
+CLASS="GUIBUTTON"
+>Preferences</SPAN
+> -->
+ <SPAN
+CLASS="GUIBUTTON"
+>Advanced</SPAN
+> --> <SPAN
+CLASS="GUIBUTTON"
+>Cache</SPAN
+> and
+ then click both <SPAN
+CLASS="QUOTE"
+>"<SPAN
+CLASS="GUIBUTTON"
+>Clear Memory Cache</SPAN
+>"</SPAN
+>
+ and <SPAN
+CLASS="QUOTE"
+>"<SPAN
+CLASS="GUIBUTTON"
+>Clear Disk Cache</SPAN
+>"</SPAN
+>.
+ In some <SPAN
+CLASS="APPLICATION"
+>Firefox</SPAN
+> versions it's
+ <SPAN
+CLASS="GUIBUTTON"
+>Tools</SPAN
+> --> <SPAN
+CLASS="GUIBUTTON"
+>Options</SPAN
+> -->
+ <SPAN
+CLASS="GUIBUTTON"
+>Privacy</SPAN
+> --> <SPAN
+CLASS="GUIBUTTON"
+>Cache</SPAN
+> and
+ then click <SPAN
+CLASS="QUOTE"
+>"<SPAN
+CLASS="GUIBUTTON"
+>Clear Cache Now</SPAN
+>"</SPAN
+>.

+></H3
+><P
+> How much of an impact depends on many things, including the CPU of the host
+ system, how aggressive the configuration is, which specific actions are being triggered,
+ the size of the page, the bandwidth of the connection, etc.</P
+><P
+> Overall, it should not slow you down any in real terms, and may actually help
+ speed things up since ads, banners and other junk are not typically being
+ retrieved and displayed. The actual processing time required by
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> itself for each page, is relatively small
+ in the overall scheme of things, and happens very quickly. This is typically
+ more than offset by time saved not downloading and rendering ad images and

+><A
+HREF="../user-manual/actions-file.html#DEANIMATE-GIFS"
+TARGET="_top"
+>deanimate-gifs</A
+></TT
+>
+ actions may cause a perceived slowdown, since the entire document
+ needs to be buffered before displaying. And on very large documents,
+ filtering may have some measurable impact. How much depends on the page size,
+ the actual definition of the filter(s), etc. See below. Most other actions
+ have little to no impact on speed.</P
+><P
+> Also, when filtering is enabled but zlib support isn't available, compression
+ is often disabled (see <A
+HREF="../user-manual/actions-file.html#PREVENT-COMPRESSION"
+TARGET="_top"
+>prevent-compression</A
+>).
+ This can have an impact on speed as well, although it's probably smaller than
+ you might think. Again, the page size, etc. will determine how much of an impact.</P

+TARGET="_top"

+CLASS="LITERAL"
+><A
+HREF="../user-manual/actions-file.html#DEANIMATE-GIFS"
+TARGET="_top"
+>deanimate-gifs</A
+></TT
+>
+ action, the entire document must be loaded into memory in order for the filtering
+ mechanism to work, and nothing is sent to the browser during this time.</P
+><P
+> The loading time typically does not really change much in real numbers, but
+ the feeling is different, because most browsers are able to start rendering
+ incomplete content, giving the user a feeling of "it works". This effect is
+ more noticeable on slower dialup connections. Extremely large documents
+ may have some impact on the time to load the page where there is filtering
+ being done. But overall, the difference should be very minimal. If there is a
+ big impact, then probably some other situation is contributing (like
+ anti-virus software).
+ </P
+><P
+> Filtering is automatically disabled for inappropriate MIME types. But note
+ that if the web server mis-reports the MIME type, then content that should
+ not be filtered, could be. <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> only knows how
+ to differentiate filterable content because of the MIME type as reported by

+>"good"</SPAN
+> content that we do want.
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is blind to the differences, and can only
+ distinguish <SPAN
+CLASS="QUOTE"
+>"good from bad"</SPAN
+> by the configuration parameters
+ <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>we</I
+></SPAN
+> give it.</P
+><P
+> <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> knows the differences in files according
+ to the <SPAN
+CLASS="QUOTE"
+>"Content Type"</SPAN
+> as reported by the webserver. If this is
+ reported accurately (e.g. <SPAN
+CLASS="QUOTE"
+>"application/zip"</SPAN
+> for a zip archive),
+ then <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> knows to ignore these where
+ appropriate. <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> potentially can filter HTML
+ as well as plain text documents, subject to configuration parameters of
+ course. Also, documents that are of an unknown type (generally assumed to be
+ <SPAN
+CLASS="QUOTE"
+>"text/plain"</SPAN
+>) can be filtered, as will those that might be
+ incorrectly reported by the webserver. If such a file is a downloaded file
+ that is intended to be saved to disk, then any content that might have been
+ altered by filtering, will be saved too, for these (probably rare) cases.</P
+><P
+> Note that versions later than 3.0.2 do NOT filter document types reported as
+ <SPAN
+CLASS="QUOTE"
+>"text/plain"</SPAN
+>. Prior to this, <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ did filter this document type.</P
+><P
+> In short, filtering is <SPAN
+CLASS="QUOTE"
+>"ON"</SPAN
+> if a) the content type as reported
+ by the webserver is appropriate <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>and</I
+></SPAN
+> b) the configuration
+ allows it (or at least does not disallow it). That's it. There is no magic
+ cookie anywhere to say this is <SPAN
+CLASS="QUOTE"
+>"good"</SPAN
+> and this is
+ <SPAN
+CLASS="QUOTE"
+>"bad"</SPAN
+>. It's the configuration that lets it all happen or not.</P
+><P
+> If you download text files, you probably do not want these to be filtered,
+ particularly if the content is source code, or other critical content. Source
+ code sometimes might be mistaken for Javascript (i.e. the kind that might
+ open a pop-up window). It is recommended to turn off filtering for download
+ sites (particularly if the content may be plain text files and you are using
+ version 3.0.2 or earlier) in your <TT
+CLASS="FILENAME"
+>user.action</TT
+> file. And
+ also, for any site or page where making <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>any</I
+></SPAN
+> changes at
+ all to the content is to be avoided.</P
+><P
+> <SPAN

+></H3
+><P
+> More than likely this is a problem with your TCP/IP networking. ZoneAlarm has
+ been reported to cause this symptom -- even if not running! The solution is
+ to either fight the ZA configuration, or uninstall ZoneAlarm, and then find

+>5.3. I just added a new rule, but the steenkin ad is
+still getting through. How?</A
+></H3
+><P
+> If the ad had been displayed before you added its URL, it will probably be
+ held in the browser's cache for some time, so it will be displayed without
+ the need for any request to the server, and <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ will not be involved. Flush the browser's caches, and then try again.</P
+><P
+> If this doesn't help, you probably have an error in the rule you
+ applied. Try pasting the full URL of the offending ad into <A
+HREF="http://config.privoxy.org/show-url-info"
+TARGET="_top"
+>http://config.privoxy.org/show-url-info</A
+>
+ and see if it really matches your new rule. Blocking ads is like blocking
+ spam: a lot of tinkering is required to stay ahead of the game. And
+ remember you need to block the URL of the ad in question, which may be
+ entirely different from the site URL itself. Most ads are hosted on different
+ servers than the main site itself. If you right-click on the ad, you should
+ be able to get all the relevant information you need. Alternately, you can
+ find the correct URL by looking at <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+> logs
+ (you may need to enable logging in the main config file if its disabled).</P
+><P
+> Below is a slightly modified real-life log snippet that originates with one
+ requested URL: <TT
+CLASS="LITERAL"
+>www.example.com</TT
+> (name of site was changed
+ for this example, the number of requests is real). You can see in this the
+ complexity of what goes into making up this one <SPAN
+CLASS="QUOTE"
+>"page"</SPAN
+>. There
+ are eight different domains involved here, with thirty two separate URLs
+ requested in all, making up all manner of images, Shockwave Flash,
+ JavaScript, CSS stylesheets, scripts, and other related content. Some of this
+ content is obviously <SPAN
+CLASS="QUOTE"
+>"good"</SPAN
+> or <SPAN
+CLASS="QUOTE"
+>"bad"</SPAN
+>, but not all.
+ Many of the more questionable looking requests, are going to outside domains
+ that seem to be identifying themselves with suspicious looking names, making
+ our job a little easier. <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> has <SPAN
+CLASS="QUOTE"
+>"crunched"</SPAN
+> (meaning caught
+ and BLOCKED) quite a few items in this example, but perhaps missed a few as well. </P

+><P
+> This is a quirk that effects the installation of
+ <SPAN

+>Privoxy</SPAN
+>, in conjunction with Internet Explorer and
+ Internet Connection Sharing on Windows 2000 and Windows XP. The symptoms may
+ appear to be corrupted or invalid DUN settings, or passwords.</P
+><P
+> When setting up an NT based Windows system with
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> you may find that things do not seem to be
+ doing what you expect. When you set your system up you will probably have set
+ up Internet Connection Sharing (ICS) with Dial up Networking (DUN) when
+ logged in with administrator privileges. You will probably have made this DUN
+ connection available to other accounts that you may have set-up on your
+ system. E.g. Mum or Dad sets up the system and makes accounts suitably
+ configured for the kids.</P
+><P
+> When setting up <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> in this environment you
+ will have to alter the proxy set-up of Internet Explorer (IE) for the
+ specific DUN connection on which you wish to use
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>. When you do this the ICS DUN set-up
+ becomes user specific. In this instance you will see no difference if you
+ change the DUN connection under the account used to set-up the connection.
+ However when you do this from another user you will notice that the DUN
+ connection changes to make available to "Me only". You will also find that
+ you have to store the password under each different user!</P
+><P
+> The reason for this is that each user's set-up for IE is user specific. Each
+ set-up DUN connection and each LAN connection in IE store the settings for
+ each user individually. As such this enforces individual configurations
+ rather than common ones. Hence the first time you use a DUN connection after
+ re-booting your system it may not perform as you expect, and prompt you for
+ the password. Just set and save the password again and all should be OK.</P

+
+<P>
+
+<B>Privoxy</B> may be invoked with the following command line

+<DL COMPACT>
+<DT><B>--help</B><DD>
+Print brief usage info and exit.
+<DT><B>--version</B><DD>
+Print version info and exit.
+<DT><B>--no-daemon</B><DD>
+Don't become a daemon, i.e. don't fork and become process group
+leader, don't detach from controlling tty, and do all logging there.
+<DT><B>--pidfile </B><I>pidfile</I><B></B><DD>
+On startup, write the process ID to <I>pidfile</I>.
+Delete the <I>pidfile</I> on exit.
+Failure to create or delete the <I>pidfile</I>
+is non-fatal. If no <B>--pidfile</B> option is given, no PID file will be used.
+<DT><B>--user </B><I>user[.group]</I><B></B><DD>
+After (optionally) writing the PID file, assume the user ID of
+<I>user</I> and the GID of
+<I>group</I>, or, if the optional
+<I>group</I> was not given, the default group of
+<I>user</I>. Exit if the privileges are not
+sufficient to do so.
+<DT><B>--chroot</B><DD>
+Before changing to the user ID given in the --user option, chroot to
+that user's home directory, i.e. make the kernel pretend to the
+<B>Privoxy</B> process that the directory tree starts
+there. If set up carefully, this can limit the impact of possible
+vulnerabilities in <B>Privoxy</B> to the files contained in
+that hierarchy.
+<DT><B>--pre-chroot-nslookup </B><I>hostname</I><B></B><DD>
+Initialize the resolver library using <I>hostname</I>
+before chroot'ing. On some systems this reduces the number of files
+that must be copied into the chroot tree.
+</DL>
+<P>
+
+If the <I>configfile</I> is not specified on the command line,
+<B>Privoxy</B> will look for a file named
+<I>config</I> in the current directory. If no
+<I>configfile</I> is found, <B>Privoxy</B> will
+fail to start.
+<A NAME="lbAE"> </A>
+<H2>DESCRIPTION</H2>
+
+<P>
+
+Privoxy is a non-caching web proxy with advanced filtering capabilities
+for enhancing privacy, modifying web page data and HTTP headers, controlling
+access, and removing ads and other obnoxious Internet junk. Privoxy has a
+flexible configuration and can be customized to suit individual needs and tastes.
+It has application for both stand-alone systems and multi-user networks.
+<P>
+
+Privoxy is Free Software and licensed under the GPL2.
+<A NAME="lbAF"> </A>
+<H2>INSTALLATION AND USAGE</H2>
+
+<P>
+
+Browsers can either be individually configured to use
+<B>Privoxy</B> as a HTTP proxy (recommended),
+or <B>Privoxy</B> can be combined with a packet
+filter to build an intercepting proxy
+(see <I>config</I>). The default setting is for
+localhost, on port 8118 (configurable in the main config file). To set the
+HTTP proxy in Firefox, go through: <B>Tools</B>;
+<B>Options</B>; <B>General</B>;
+<B>Connection Settings</B>;
+<B>Manual Proxy Configuration</B>.
+<P>
+
+For Internet Explorer, go through: <B>Tools</B>;
+<B>Internet Properties</B>; <B>Connections</B>;
+<B>LAN Settings</B>.
+<P>
+
+The Secure (SSL) Proxy should also be set to the same values, otherwise
+https: URLs will not be proxied. Note: <B>Privoxy</B> can only
+proxy HTTP and HTTPS traffic. Do not try it with FTP or other protocols.
+HTTPS presents some limitations, and not all features will work with HTTPS
+connections.
+<P>
+
+For other browsers, check the documentation.
+<A NAME="lbAG"> </A>
+<H2>CONFIGURATION</H2>
+
+<P>
+
+<B>Privoxy</B> can be configured with the various configuration
+files. The default configuration files are: <I>config</I>,
+<I>default.filter</I>, <I>default.action</I> and
+<I>default.action</I>. <I>user.action</I> should
+be used for locally defined exceptions to the default rules in
+<I>match-all.action</I> and <I>default.action</I>,
+and <I>user.filter</I> for locally defined filters. These are
+well commented. On Unix and Unix-like systems, these are located in
+<I>/etc/privoxy/</I> by default.
+<P>
+
+<B>Privoxy</B> uses the concept of <B>actions</B>
+in order to manipulate the data stream between the browser and remote sites.
+There are various actions available with specific functions for such things
+as blocking web sites, managing cookies, etc. These actions can be invoked
+individually or combined, and used against individual URLs, or groups of URLs
+that can be defined using wildcards and regular expressions. The result is
+that the user has greatly enhanced control and freedom.
+<P>
+
+The actions list (ad blocks, etc) can also be configured with your
+web browser at <A HREF="http://config.privoxy.org/">http://config.privoxy.org/</A>
+(assuming the configuration allows it).
+<B>Privoxy's</B> configuration parameters can also be viewed at
+the same page. In addition, <B>Privoxy</B> can be toggled on/off.
+This is an internal page, and does not require Internet access.
+<P>
+
+See the <I>User Manual</I> for a detailed
+explanation of installation, general usage, all configuration options, new
+features and notes on upgrading.

+Various other files should be included, but may vary depending on platform
+and build configuration. Additional documentation should be included in the local
+documentation directory.
+<A NAME="lbAI"> </A>
+<H2>SIGNALS</H2>
+
+<P>
+
+<B>Privoxy</B> terminates on the <B>SIGINT</B>,
+<B>SIGTERM</B> and <B>SIGABRT</B> signals. Log
+rotation scripts may cause a re-opening of the logfile by sending a
+<B>SIGHUP</B> to <B>Privoxy</B>. Note that unlike
+other daemons, <B>Privoxy</B> does not need to be made aware of
+config file changes by <B>SIGHUP</B> -- it will detect them
+automatically.

+<H2>NOTES</H2>

+> The list of actions files to be used are defined in the main configuration
+ file, and are processed in the order they are defined (e.g.
+ <TT
+CLASS="FILENAME"
+>default.action</TT
+> is typically processed before
+ <TT
+CLASS="FILENAME"
+>user.action</TT
+>). The content of these can all be viewed and
+ edited from <A
+HREF="http://config.privoxy.org/show-status"
+TARGET="_top"
+>http://config.privoxy.org/show-status</A
+>.
+ The over-riding principle when applying actions, is that the last action that
+ matches a given URL wins. The broadest, most general rules go first
+ (defined in <TT
+CLASS="FILENAME"
+>default.action</TT
+>),
+ followed by any exceptions (typically also in
+ <TT
+CLASS="FILENAME"
+>default.action</TT
+>), which are then followed lastly by any
+ local preferences (typically in <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>user</I
+></SPAN
+><TT
+CLASS="FILENAME"
+>.action</TT
+>).
+ Generally, <TT
+CLASS="FILENAME"
+>user.action</TT
+> has the last word.
+ </P
+><P
+> An actions file typically has multiple sections. If you want to use
+ <SPAN
+CLASS="QUOTE"
+>"aliases"</SPAN
+> in an actions file, you have to place the (optional)
+ <A
+HREF="actions-file.html#ALIASES"
+>alias section</A
+> at the top of that file.
+ Then comes the default set of rules which will apply universally to all
+ sites and pages (be <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>very careful</I
+></SPAN
+> with using such a
+ universal set in <TT
+CLASS="FILENAME"
+>user.action</TT
+> or any other actions file after
+ <TT
+CLASS="FILENAME"
+>default.action</TT
+>, because it will override the result
+ from consulting any previous file). And then below that,
+ exceptions to the defined universal policies. You can regard
+ <TT
+CLASS="FILENAME"
+>user.action</TT
+> as an appendix to <TT
+CLASS="FILENAME"
+>default.action</TT
+>,
+ with the advantage that it is a separate file, which makes preserving your
+ personal settings across <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> upgrades easier.</P
+><P
+>
+ Actions can be used to block anything you want, including ads, banners, or
+ just some obnoxious URL whose content you would rather not see. Cookies can be accepted
+ or rejected, or accepted only during the current browser session (i.e. not
+ written to disk), content can be modified, some JavaScripts tamed, user-tracking
+ fooled, and much more. See below for a <A
+HREF="actions-file.html#ACTIONS"

+> Note that some <A

+>actions</A
+>, like cookie suppression
+ or script disabling, may render some sites unusable that rely on these
+ techniques to work properly. Finding the right mix of actions is not always easy and
+ certainly a matter of personal taste. And, things can always change, requiring
+ refinements in the configuration. In general, it can be said that the more
+ <SPAN
+CLASS="QUOTE"
+>"aggressive"</SPAN
+> your default settings (in the top section of the
+ actions file) are, the more exceptions for <SPAN
+CLASS="QUOTE"
+>"trusted"</SPAN

+ will have to make later. If, for example, you want to crunch all cookies per
+ default, you'll have to make exceptions from that rule for sites that you
+ regularly use and that require cookies for actually useful purposes, like maybe
+ your bank, favorite shop, or newspaper.</P
+><P
+> We have tried to provide you with reasonable rules to start from in the
+ distribution actions files. But there is no general rule of thumb on these
+ things. There just are too many variables, and sites are constantly changing.

+>8.2. How to Edit</A
+></H2
+><P
+> The easiest way to edit the actions files is with a browser by
+ using our browser-based editor, which can be reached from <A
+HREF="http://config.privoxy.org/show-status"
+TARGET="_top"
+>http://config.privoxy.org/show-status</A
+>.
+ Note: the config file option <A
+HREF="config.html#ENABLE-EDIT-ACTIONS"
+>enable-edit-actions</A
+> must be enabled for
+ this to work. The editor allows both fine-grained control over every single
+ feature on a per-URL basis, and easy choosing from wholesale sets of defaults
+ like <SPAN
+CLASS="QUOTE"
+>"Cautious"</SPAN
+>, <SPAN
+CLASS="QUOTE"
+>"Medium"</SPAN
+> or
+ <SPAN
+CLASS="QUOTE"
+>"Advanced"</SPAN
+>. Warning: the <SPAN
+CLASS="QUOTE"
+>"Advanced"</SPAN
+> setting is more
+ aggressive, and will be more likely to cause problems for some sites.
+ Experienced users only!
+ </P
+><P
+> If you prefer plain text editing to GUIs, you can of course also directly edit the
+ the actions files with your favorite text editor. Look at
+ <TT
+CLASS="FILENAME"
+>default.action</TT
+> which is richly commented with many
+ good examples.</P

+>8.3. How Actions are Applied to Requests</A
+></H2
+><P
+> Actions files are divided into sections. There are special sections,
+ like the <SPAN
+CLASS="QUOTE"
+>"<A
+HREF="actions-file.html#ALIASES"
+>alias</A
+>"</SPAN
+> sections which will
+ be discussed later. For now let's concentrate on regular sections: They have a
+ heading line (often split up to multiple lines for readability) which consist
+ of a list of actions, separated by whitespace and enclosed in curly braces.
+ Below that, there is a list of URL and tag patterns, each on a separate line.</P
+><P
+> To determine which actions apply to a request, the URL of the request is
+ compared to all URL patterns in each <SPAN
+CLASS="QUOTE"
+>"action file"</SPAN
+>.
+ Every time it matches, the list of applicable actions for the request is
+ incrementally updated, using the heading of the section in which the
+ pattern is located. The same is done again for tags and tag patterns later on.</P
+><P
+> If multiple applying sections set the same action differently,
+ the last match wins. If not, the effects are aggregated.
+ E.g. a URL might match a regular section with a heading line of <TT
+CLASS="LITERAL"
+>{
+ +<A
+HREF="actions-file.html#HANDLE-AS-IMAGE"
+>handle-as-image</A
+> }</TT
+>,
+ then later another one with just <TT
+CLASS="LITERAL"
+>{
+ +<A
+HREF="actions-file.html#BLOCK"
+>block</A
+> }</TT
+>, resulting
+ in <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>both</I
+></SPAN
+> actions to apply. And there may well be
+ cases where you will want to combine actions together. Such a section then
+ might look like:</P

+><P
+> Once a new tag is added, Privoxy checks right away if it's matched by one
+ of the tag patterns and updates the action settings accordingly. As a result
+ tags can be used to activate other tagger actions, as long as these other
+ taggers look for headers that haven't already be parsed.</P
+><P
+> For example you could tag client requests which use the
+ <TT
+CLASS="LITERAL"
+>POST</TT
+> method,
+ then use this tag to activate another tagger that adds a tag if cookies
+ are sent, and then use a block action based on the cookie tag. This allows
+ the outcome of one action, to be input into a subsequent action. However if
+ you'd reverse the position of the described taggers, and activated the

+ The method tagger would look for the request line, but at the time
+ the cookie tag is created, the request line has already been parsed.</P

+ Many sites, like yahoo.com, don't just link to other sites. Instead, they
+ will link to some script on their own servers, giving the destination as a
+ parameter, which will then redirect you to the final target. URLs
+ resulting from this scheme typically look like:
+ <SPAN
+CLASS="QUOTE"
+>"http://www.example.org/click-tracker.cgi?target=http%3a//www.example.net/"</SPAN
+>.
+ </P
+><P
+> Sometimes, there are even multiple consecutive redirects encoded in the
+ URL. These redirections via scripts make your web browsing more traceable,
+ since the server from which you follow such a link can see where you go
+ to. Apart from that, valuable bandwidth and time is wasted, while your
+ browser asks the server for one redirect after the other. Plus, it feeds
+ the advertisers.
+ </P
+><P
+> This feature is currently not very smart and is scheduled for improvement.
+ If it is enabled by default, you will have to create some exceptions to
+ this action. It can lead to failures in several ways:
+ </P
+><P
+> Not every URLs with other URLs as parameters is evil.
+ Some sites offer a real service that requires this information to work.
+ For example a validation service needs to know, which document to validate.
+ <TT
+CLASS="LITERAL"
+>fast-redirects</TT
+> assumes that every URL parameter that
+ looks like another URL is a redirection target, and will always redirect to
+ the last one. Most of the time the assumption is correct, but if it isn't,
+ the user gets redirected anyway.
+ </P
+><P
+> Another failure occurs if the URL contains other parameters after the URL parameter.
+ The URL:
+ <SPAN
+CLASS="QUOTE"
+>"http://www.example.org/?redirect=http%3a//www.example.net/&foo=bar"</SPAN
+>.
+ contains the redirection URL <SPAN
+CLASS="QUOTE"
+>"http://www.example.net/"</SPAN
+>,
+ followed by another parameter. <TT
+CLASS="LITERAL"
+>fast-redirects</TT
+> doesn't know that
+ and will cause a redirect to <SPAN
+CLASS="QUOTE"
+>"http://www.example.net/&foo=bar"</SPAN
+>.
+ Depending on the target server configuration, the parameter will be silently ignored
+ or lead to a <SPAN
+CLASS="QUOTE"
+>"page not found"</SPAN
+> error. You can prevent this problem by
+ first using the <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#REDIRECT"
+>redirect</A
+></TT
+> action
+ to remove the last part of the URL, but it requires a little effort.
+ </P
+><P
+> To detect a redirection URL, <TT
+CLASS="LITERAL"
+>fast-redirects</TT
+> only
+ looks for the string <SPAN
+CLASS="QUOTE"
+>"http://"</SPAN
+>, either in plain text
+ (invalid but often used) or encoded as <SPAN
+CLASS="QUOTE"
+>"http%3a//"</SPAN
+>.
+ Some sites use their own URL encoding scheme, encrypt the address
+ of the target server or replace it with a database id. In theses cases
+ <TT
+CLASS="LITERAL"
+>fast-redirects</TT
+> is fooled and the request reaches the
+ redirection server where it probably gets logged.

+> There are two main reasons to use aliases: One is to save typing for frequently

+ <SPAN

+ by their purpose also makes your actions files more readable.</P
+><P
+> Currently, there is one big drawback to using aliases, though:
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>'s built-in web-based action file
+ editor honors aliases when reading the actions files, but it expands
+ them before writing. So the effects of your aliases are of course preserved,

+>book</A
+> ;-)</P
+><P
+> Regular expressions provide a language to describe patterns that can be
+ run against strings of characters (letter, numbers, etc), to see if they
+ match the string or not. The patterns are themselves (sometimes complex)
+ strings of literal characters, combined with wild-cards, and other special
+ characters, called meta-characters. The <SPAN
+CLASS="QUOTE"
+>"meta-characters"</SPAN
+> have
+ special meanings and are used to build complex patterns to be matched against.
+ Perl Compatible Regular Expressions are an especially convenient
+ <SPAN
+CLASS="QUOTE"
+>"dialect"</SPAN
+> of the regular expression language.</P
+><P
+> To make a simple analogy, we do something similar when we use wild-card
+ characters when listing files with the <B
+CLASS="COMMAND"
+>dir</B
+> command in DOS.
+ <TT
+CLASS="LITERAL"
+>*.*</TT
+> matches all filenames. The <SPAN
+CLASS="QUOTE"
+>"special"</SPAN
+>
+ character here is the asterisk which matches any and all characters. We can be
+ more specific and use <TT
+CLASS="LITERAL"
+>?</TT
+> to match just individual
+ characters. So <SPAN
+CLASS="QUOTE"
+>"dir file?.text"</SPAN
+> would match
+ <SPAN
+CLASS="QUOTE"
+>"file1.txt"</SPAN
+>, <SPAN
+CLASS="QUOTE"
+>"file2.txt"</SPAN
+>, etc. We are pattern
+ matching, using a similar technique to <SPAN
+CLASS="QUOTE"
+>"regular expressions"</SPAN
+>!</P
+><P
+> Regular expressions do essentially the same thing, but are much, much more
+ powerful. There are many more <SPAN
+CLASS="QUOTE"
+>"special characters"</SPAN
+> and ways of
+ building complex patterns however. Let's look at a few of the common ones,

+> These are just some of the ones you are likely to use when matching URLs with

+ be more illuminating:</P
+><P
+> <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+><TT
+CLASS="LITERAL"
+>/.*/banners/.*</TT
+></I
+></SPAN
+> - A simple example
+ that uses the common combination of <SPAN
+CLASS="QUOTE"
+>"."</SPAN
+> and <SPAN
+CLASS="QUOTE"
+>"*"</SPAN
+> to
+ denote any character, zero or more times. In other words, any string at all.
+ So we start with a literal forward slash, then our regular expression pattern
+ (<SPAN
+CLASS="QUOTE"
+>".*"</SPAN
+>) another literal forward slash, the string
+ <SPAN
+CLASS="QUOTE"
+>"banners"</SPAN
+>, another forward slash, and lastly another
+ <SPAN
+CLASS="QUOTE"
+>".*"</SPAN
+>. We are building
+ a directory path here. This will match any file with the path that has a
+ directory named <SPAN
+CLASS="QUOTE"
+>"banners"</SPAN
+> in it. The <SPAN
+CLASS="QUOTE"
+>".*"</SPAN
+> matches
+ any characters, and this could conceivably be more forward slashes, so it
+ might expand into a much longer looking path. For example, this could match:
+ <SPAN
+CLASS="QUOTE"
+>"/eye/hate/spammers/banners/annoy_me_please.gif"</SPAN
+>, or just
+ <SPAN
+CLASS="QUOTE"
+>"/banners/annoying.html"</SPAN
+>, or almost an infinite number of other
+ possible combinations, just so it has <SPAN
+CLASS="QUOTE"
+>"banners"</SPAN
+> in the path
+ somewhere.</P
+><P
+> And now something a little more complex:</P
+><P
+> <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+><TT
+CLASS="LITERAL"
+>/.*/adv((er)?ts?|ertis(ing|ements?))?/</TT
+></I
+></SPAN
+> -
+ We have several literal forward slashes again (<SPAN
+CLASS="QUOTE"
+>"/"</SPAN
+>), so we are
+ building another expression that is a file path statement. We have another
+ <SPAN
+CLASS="QUOTE"
+>".*"</SPAN
+>, so we are matching against any conceivable sub-path, just so
+ it matches our expression. The only true literal that <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>must
+ match</I
+></SPAN
+> our pattern is <SPAN
+CLASS="APPLICATION"
+>adv</SPAN
+>, together with
+ the forward slashes. What comes after the <SPAN
+CLASS="QUOTE"
+>"adv"</SPAN
+> string is the
+ interesting part. </P
+><P
+> Remember the <SPAN
+CLASS="QUOTE"
+>"?"</SPAN
+> means the preceding expression (either a
+ literal character or anything grouped with <SPAN
+CLASS="QUOTE"
+>"(...)"</SPAN
+> in this case)
+ can exist or not, since this means either zero or one match. So
+ <SPAN
+CLASS="QUOTE"
+>"((er)?ts?|ertis(ing|ements?))"</SPAN
+> is optional, as are the
+ individual sub-expressions: <SPAN
+CLASS="QUOTE"
+>"(er)"</SPAN
+>,
+ <SPAN
+CLASS="QUOTE"
+>"(ing|ements?)"</SPAN
+>, and the <SPAN
+CLASS="QUOTE"
+>"s"</SPAN
+>. The <SPAN
+CLASS="QUOTE"
+>"|"</SPAN
+>
+ means <SPAN
+CLASS="QUOTE"
+>"or"</SPAN
+>. We have two of those. For instance,
+ <SPAN
+CLASS="QUOTE"
+>"(ing|ements?)"</SPAN
+>, can expand to match either <SPAN
+CLASS="QUOTE"
+>"ing"</SPAN
+>
+ <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>OR</I
+></SPAN
+> <SPAN
+CLASS="QUOTE"
+>"ements?"</SPAN
+>. What is being done here, is an
+ attempt at matching as many variations of <SPAN
+CLASS="QUOTE"
+>"advertisement"</SPAN
+>, and
+ similar, as possible. So this would expand to match just <SPAN
+CLASS="QUOTE"
+>"adv"</SPAN
+>,
+ or <SPAN
+CLASS="QUOTE"
+>"advert"</SPAN
+>, or <SPAN
+CLASS="QUOTE"
+>"adverts"</SPAN
+>, or
+ <SPAN
+CLASS="QUOTE"
+>"advertising"</SPAN
+>, or <SPAN
+CLASS="QUOTE"
+>"advertisement"</SPAN
+>, or
+ <SPAN
+CLASS="QUOTE"
+>"advertisements"</SPAN
+>. You get the idea. But it would not match
+ <SPAN
+CLASS="QUOTE"
+>"advertizements"</SPAN
+> (with a <SPAN
+CLASS="QUOTE"
+>"z"</SPAN
+>). We could fix that by
+ changing our regular expression to:
+ <SPAN
+CLASS="QUOTE"
+>"/.*/adv((er)?ts?|erti(s|z)(ing|ements?))?/"</SPAN
+>, which would then match
+ either spelling.</P
+><P
+> <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+><TT
+CLASS="LITERAL"
+>/.*/advert[0-9]+\.(gif|jpe?g)</TT
+></I
+></SPAN
+> - Again
+ another path statement with forward slashes. Anything in the square brackets
+ <SPAN
+CLASS="QUOTE"
+>"[ ]"</SPAN
+> can be matched. This is using <SPAN
+CLASS="QUOTE"
+>"0-9"</SPAN
+> as a
+ shorthand expression to mean any digit one through nine. It is the same as
+ saying <SPAN
+CLASS="QUOTE"
+>"0123456789"</SPAN
+>. So any digit matches. The <SPAN
+CLASS="QUOTE"
+>"+"</SPAN
+>
+ means one or more of the preceding expression must be included. The preceding
+ expression here is what is in the square brackets -- in this case, any digit
+ one through nine. Then, at the end, we have a grouping: <SPAN
+CLASS="QUOTE"
+>"(gif|jpe?g)"</SPAN
+>.
+ This includes a <SPAN
+CLASS="QUOTE"
+>"|"</SPAN
+>, so this needs to match the expression on
+ either side of that bar character also. A simple <SPAN
+CLASS="QUOTE"
+>"gif"</SPAN
+> on one side, and the other
+ side will in turn match either <SPAN
+CLASS="QUOTE"
+>"jpeg"</SPAN
+> or <SPAN
+CLASS="QUOTE"
+>"jpg"</SPAN
+>,
+ since the <SPAN
+CLASS="QUOTE"
+>"?"</SPAN
+> means the letter <SPAN
+CLASS="QUOTE"
+>"e"</SPAN
+> is optional and
+ can be matched once or not at all. So we are building an expression here to
+ match image GIF or JPEG type image file. It must include the literal
+ string <SPAN
+CLASS="QUOTE"
+>"advert"</SPAN
+>, then one or more digits, and a <SPAN
+CLASS="QUOTE"
+>"."</SPAN
+>
+ (which is now a literal, and not a special character, since it is escaped
+ with <SPAN
+CLASS="QUOTE"
+>"\"</SPAN
+>), and lastly either <SPAN
+CLASS="QUOTE"
+>"gif"</SPAN
+>, or
+ <SPAN
+CLASS="QUOTE"
+>"jpeg"</SPAN
+>, or <SPAN
+CLASS="QUOTE"
+>"jpg"</SPAN
+>. Some possible matches would
+ include: <SPAN
+CLASS="QUOTE"
+>"//advert1.jpg"</SPAN
+>,
+ <SPAN
+CLASS="QUOTE"
+>"/nasty/ads/advert1234.gif"</SPAN
+>,
+ <SPAN
+CLASS="QUOTE"
+>"/banners/from/hell/advert99.jpg"</SPAN
+>. It would not match
+ <SPAN
+CLASS="QUOTE"
+>"advert1.gif"</SPAN
+> (no leading slash), or
+ <SPAN
+CLASS="QUOTE"
+>"/adverts232.jpg"</SPAN
+> (the expression does not include an
+ <SPAN
+CLASS="QUOTE"
+>"s"</SPAN
+>), or <SPAN
+CLASS="QUOTE"
+>"/advert1.jsp"</SPAN
+> (<SPAN
+CLASS="QUOTE"
+>"jsp"</SPAN
+> is not
+ in the expression anywhere).</P
+><P
+> We are barely scratching the surface of regular expressions here so that you

+><P
+> Let's take a quick look at how some of <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+>
+ core features are triggered, and the ensuing sequence of events when a web
+ page is requested by your browser:</P
+><P
+> <P
+></P
+><UL
+><LI
+><P
+> First, your web browser requests a web page. The browser knows to send
+ the request to <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>, which will in turn,
+ relay the request to the remote web server after passing the following
+ tests:
+ </P
+></LI
+><LI
+><P
+> <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> traps any request for its own internal CGI
+ pages (e.g <A
+HREF="http://p.p/"
+TARGET="_top"
+>http://p.p/</A
+>) and sends the CGI page back to the browser.
+ </P
+></LI
+><LI
+><P
+> Next, <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> checks to see if the URL
+ matches any <A
+HREF="actions-file.html#BLOCK"
+><SPAN
+CLASS="QUOTE"
+>"+block"</SPAN
+></A
+> patterns. If
+ so, the URL is then blocked, and the remote web server will not be contacted.
+ <A
+HREF="actions-file.html#HANDLE-AS-IMAGE"
+><SPAN
+CLASS="QUOTE"
+>"+handle-as-image"</SPAN
+></A
+>
+ and
+ <A
+HREF="actions-file.html#HANDLE-AS-EMPTY-DOCUMENT"
+><SPAN
+CLASS="QUOTE"
+>"+handle-as-empty-document"</SPAN
+></A
+>
+ are then checked, and if there is no match, an
+ HTML <SPAN
+CLASS="QUOTE"
+>"BLOCKED"</SPAN
+> page is sent back to the browser. Otherwise, if
+ it does match, an image is returned for the former, and an empty text
+ document for the latter. The type of image would depend on the setting of
+ <A
+HREF="actions-file.html#SET-IMAGE-BLOCKER"
+><SPAN
+CLASS="QUOTE"
+>"+set-image-blocker"</SPAN
+></A
+>
+ (blank, checkerboard pattern, or an HTTP redirect to an image elsewhere).
+ </P
+></LI
+><LI
+><P
+> Untrusted URLs are blocked. If URLs are being added to the
+ <TT
+CLASS="FILENAME"
+>trust</TT
+> file, then that is done.
+ </P
+></LI
+><LI
+><P
+> If the URL pattern matches the <A
+HREF="actions-file.html#FAST-REDIRECTS"
+><SPAN
+CLASS="QUOTE"
+>"+fast-redirects"</SPAN
+></A
+> action,
+ it is then processed. Unwanted parts of the requested URL are stripped.
+ </P
+></LI
+><LI
+><P
+> Now the rest of the client browser's request headers are processed. If any
+ of these match any of the relevant actions (e.g. <A
+HREF="actions-file.html#HIDE-USER-AGENT"
+><SPAN
+CLASS="QUOTE"
+>"+hide-user-agent"</SPAN
+></A
+>,
+ etc.), headers are suppressed or forged as determined by these actions and
+ their parameters.
+ </P
+></LI
+><LI
+><P
+> Now the web server starts sending its response back (i.e. typically a web
+ page).
+ </P
+></LI
+><LI
+><P
+> First, the server headers are read and processed to determine, among other
+ things, the MIME type (document type) and encoding. The headers are then
+ filtered as determined by the
+ <A
+HREF="actions-file.html#CRUNCH-INCOMING-COOKIES"
+><SPAN
+CLASS="QUOTE"
+>"+crunch-incoming-cookies"</SPAN
+></A
+>,
+ <A

+><SPAN
+CLASS="QUOTE"
+>"+deanimate-gifs"</SPAN
+></A
+>
+ action applies (and the document type fits the action), the rest of the page is
+ read into memory (up to a configurable limit). Then the filter rules (from
+ <TT
+CLASS="FILENAME"
+>default.filter</TT
+> and any other filter files) are
+ processed against the buffered content. Filters are applied in the order
+ they are specified in one of the filter files. Animated GIFs, if present,
+ are reduced to either the first or last frame, depending on the action
+ setting.The entire page, which is now filtered, is then sent by
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> back to your browser.
+ </P
+><P
+> If neither a <A

+ or <A
+HREF="actions-file.html#DEANIMATE-GIFS"
+><SPAN

+>
+ matches, then <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> passes the raw data through
+ to the client browser as it becomes available.
+ </P
+></LI
+><LI
+><P
+> As the browser receives the now (possibly filtered) page content, it
+ reads and then requests any URLs that may be embedded within the page
+ source, e.g. ad images, stylesheets, JavaScript, other HTML documents (e.g.
+ frames), sounds, etc. For each of these objects, the browser issues a
+ separate request (this is easily viewable in <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+>
+ logs). And each such request is in turn processed just as above. Note that a
+ complex web page will have many, many such embedded URLs. If these
+ secondary requests are to a different server, then quite possibly a very
+ differing set of actions is triggered.
+ </P
+></LI
+></UL

+><P
+> NOTE: This is somewhat of a simplistic overview of what happens with each URL
+ request. For the sake of brevity and simplicity, we have focused on
+ <SPAN

+><P
+> The way <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> applies
+ <A
+HREF="actions-file.html#ACTIONS"
+>actions</A
+> and <A
+HREF="actions-file.html#FILTER"
+>filters</A
+>
+ to any given URL can be complex, and not always so
+ easy to understand what is happening. And sometimes we need to be able to
+ <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>see</I
+></SPAN
+> just what <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is
+ doing. Especially, if something <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is doing
+ is causing us a problem inadvertently. It can be a little daunting to look at
+ the actions and filters files themselves, since they tend to be filled with
+ <A
+HREF="appendix.html#REGEX"
+>regular expressions</A
+> whose consequences are not
+ always so obvious. </P
+><P
+> One quick test to see if <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is causing a problem
+ or not, is to disable it temporarily. This should be the first troubleshooting
+ step. See <A
+HREF="appendix.html#BOOKMARKLETS"
+>the Bookmarklets</A
+> section on a quick
+ and easy way to do this (be sure to flush caches afterward!). Looking at the
+ logs is a good idea too. (Note that both the toggle feature and logging are
+ enabled via <TT
+CLASS="FILENAME"
+>config</TT
+> file settings, and may need to be
+ turned <SPAN
+CLASS="QUOTE"
+>"on"</SPAN
+>.)</P
+><P
+> Another easy troubleshooting step to try is if you have done any
+ customization of your installation, revert back to the installed
+ defaults and see if that helps. There are times the developers get complaints
+ about one thing or another, and the problem is more related to a customized
+ configuration issue.</P
+><P
+> <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> also provides the
+ <A
+HREF="http://config.privoxy.org/show-url-info"
+TARGET="_top"
+>http://config.privoxy.org/show-url-info</A
+>
+ page that can show us very specifically how <SPAN
+CLASS="APPLICATION"
+>actions</SPAN
+>
+ are being applied to any given URL. This is a big help for troubleshooting.</P
+><P
+> First, enter one URL (or partial URL) at the prompt, and then
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> will tell us
+ how the current configuration will handle it. This will not
+ help with filtering effects (i.e. the <A
+HREF="actions-file.html#FILTER"
+><SPAN
+CLASS="QUOTE"
+>"+filter"</SPAN
+></A
+> action) from
+ one of the filter files since this is handled very
+ differently and not so easy to trap! It also will not tell you about any other
+ URLs that may be embedded within the URL you are testing. For instance, images
+ such as ads are expressed as URLs within the raw page source of HTML pages. So
+ you will only get info for the actual URL that is pasted into the prompt area
+ -- not any sub-URLs. If you want to know about embedded URLs like ads, you
+ will have to dig those out of the HTML source. Use your browser's <SPAN
+CLASS="QUOTE"
+>"View
+ Page Source"</SPAN
+> option for this. Or right click on the ad, and grab the
+ URL.</P

+><SPAN
+CLASS="QUOTE"
+>"actions"</SPAN
+></A
+>, and
+ which ones match for our test case, <SPAN
+CLASS="QUOTE"
+>"google.com"</SPAN
+>.
+ Displayed is all the actions that are available to us. Remember,

+CLASS="LITERAL"
+>+</TT

+CLASS="QUOTE"
+>"on"</SPAN
+>. <TT
+CLASS="LITERAL"
+>-</TT
+>
+ denotes <SPAN
+CLASS="QUOTE"
+>"off"</SPAN
+>. So some are <SPAN
+CLASS="QUOTE"
+>"on"</SPAN
+> here, but many
+ are <SPAN
+CLASS="QUOTE"
+>"off"</SPAN
+>. Each example we try may provide a slightly different
+ end result, depending on our configuration directives.</P
+><P
+> The first listing
+ is for our <TT
+CLASS="FILENAME"
+>default.action</TT
+> file. The large, multi-line
+ listing, is how the actions are set to match for all URLs, i.e. our default
+ settings. If you look at your <SPAN
+CLASS="QUOTE"
+>"actions"</SPAN
+> file, this would be the
+ section just below the <SPAN
+CLASS="QUOTE"
+>"aliases"</SPAN
+> section near the top. This
+ will apply to all URLs as signified by the single forward slash at the end
+ of the listing -- <SPAN
+CLASS="QUOTE"
+>" / "</SPAN
+>.</P
+><P
+> But we have defined additional actions that would be exceptions to these general
+ rules, and then we list specific URLs (or patterns) that these exceptions
+ would apply to. Last match wins. Just below this then are two explicit
+ matches for <SPAN
+CLASS="QUOTE"
+>".google.com"</SPAN
+>. The first is negating our previous
+ cookie setting, which was for <A
+HREF="actions-file.html#SESSION-COOKIES-ONLY"
+><SPAN
+CLASS="QUOTE"
+>"+session-cookies-only"</SPAN
+></A
+>
+ (i.e. not persistent). So we will allow persistent cookies for google, at
+ least that is how it is in this example. The second turns
+ <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>off</I
+></SPAN
+> any <A
+HREF="actions-file.html#FAST-REDIRECTS"
+><SPAN
+CLASS="QUOTE"
+>"+fast-redirects"</SPAN
+></A
+>
+ action, allowing this to take place unmolested. Note that there is a leading
+ dot here -- <SPAN
+CLASS="QUOTE"
+>".google.com"</SPAN
+>. This will match any hosts and
+ sub-domains, in the google.com domain also, such as
+ <SPAN
+CLASS="QUOTE"
+>"www.google.com"</SPAN
+> or <SPAN
+CLASS="QUOTE"
+>"mail.google.com"</SPAN
+>. But it would not
+ match <SPAN
+CLASS="QUOTE"
+>"www.google.de"</SPAN
+>! So, apparently, we have these two actions
+ defined as exceptions to the general rules at the top somewhere in the lower
+ part of our <TT
+CLASS="FILENAME"
+>default.action</TT
+> file, and
+ <SPAN
+CLASS="QUOTE"
+>"google.com"</SPAN
+> is referenced somewhere in these latter sections.</P
+><P
+> Then, for our <TT
+CLASS="FILENAME"
+>user.action</TT
+> file, we again have no hits.
+ So there is nothing google-specific that we might have added to our own, local
+ configuration. If there was, those actions would over-rule any actions from
+ previously processed files, such as <TT
+CLASS="FILENAME"
+>default.action</TT
+>.
+ <TT
+CLASS="FILENAME"
+>user.action</TT
+> typically has the last word. This is the
+ best place to put hard and fast exceptions,</P

+ AmigaOS these are all in the same directory as the
+ <SPAN

+>
+ on Windows. This is a required file.

+><P
+> <TT
+CLASS="FILENAME"
+>match-all.action</TT
+> is used to define which <SPAN
+CLASS="QUOTE"

+ relating to banner-blocking, images, pop-ups, content modification, cookie handling
+ etc should be applied by default. It should be the first actions file loaded.
+ </P
+><P
+> <TT
+CLASS="FILENAME"
+>default.action</TT
+> defines many exceptions (both positive and negative)
+ from the default set of actions that's configured in <TT
+CLASS="FILENAME"
+>match-all.action</TT
+>.
+ It should be the second actions file loaded and shouldn't be edited by the user.
+ </P
+><P
+> Multiple actions files may be defined in <TT
+CLASS="FILENAME"
+>config</TT
+>. These
+ are processed in the order they are defined. Local customizations and locally
+ preferred exceptions to the default policies as defined in
+ <TT
+CLASS="FILENAME"
+>match-all.action</TT
+> (which you will most probably want
+ to define sooner or later) are best applied in <TT
+CLASS="FILENAME"
+>user.action</TT
+>,
+ where you can preserve them across upgrades. The file isn't installed by all
+ installers, but you can easily create it yourself with a text editor.

+ viewable text as well as embedded HTML and JavaScript, and whatever else
+ lurks on any given web page. The filtering jobs are only pre-defined here;
+ whether to apply them or not is up to the actions files.
+ <TT
+CLASS="FILENAME"
+>default.filter</TT

+> character to denote a
+ comment (the rest of the line will be ignored) and understand line continuation
+ through placing a backslash ("<TT
+CLASS="LITERAL"
+>\</TT

+ in a line. If the <TT
+CLASS="LITERAL"
+>#</TT
+> is preceded by a backslash, it looses
+ its special function. Placing a <TT
+CLASS="LITERAL"
+>#</TT
+> in front of an otherwise

+></H2
+><P
+> A long time ago, there was the
+ <A
+HREF="http://www.junkbusters.com/ijb.html"
+TARGET="_top"
+><SPAN
+CLASS="APPLICATION"
+>Internet Junkbuster</SPAN
+></A
+>,
+ by Anonymous Coders and <A
+HREF="http://www.junkbusters.com/"
+TARGET="_top"
+>Junkbusters
+ Corporation</A
+>. This saved many users a lot of pain in the early days of
+ web advertising and user tracking.</P
+><P
+> But the web, its protocols and standards, and with it, the techniques for
+ forcing ads on users, give up autonomy over their browsing, and
+ for tracking them, keeps evolving. Unfortunately, the <SPAN
+CLASS="APPLICATION"
+>Internet
+ Junkbuster</SPAN
+> did not. Version 2.0.2, published in 1998, was
+ (and is) the last official
+ <A
+HREF="http://www.junkbusters.com/ijbdist.html#release"
+TARGET="_top"
+>release</A
+>
+ available from <A
+HREF="http://www.junkbusters.com"
+TARGET="_top"
+>Junkbusters Corporation</A
+>.
+ Fortunately, it had been released under the GNU
+ <A
+HREF="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
+TARGET="_top"
+>GPL</A
+>,
+ which allowed further development by others.</P
+><P
+> So Stefan Waldherr started maintaining an improved version of the
+ software, to which eventually a number of people contributed patches.
+ It could already replace banners with a transparent image, and had a first
+ version of pop-up killing, but it was still very closely based on the
+ original, with all its limitations, such as the lack of HTTP/1.1 support,
+ flexible per-site configuration, or content modification. The last release
+ from this effort was version 2.0.2-10, published in 2000.</P
+><P
+> Then, some
+ <A
+HREF="http://www.privoxy.org/user-manual/copyright.html#AUTHORS"
+TARGET="_top"
+>developers</A
+>
+ picked up the thread, and started turning the software inside out, upside down,
+ and then reassembled it, adding many
+ <A
+HREF="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
+TARGET="_top"
+>new
+ features</A
+> along the way.</P
+><P
+> The result of this is <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>, whose first
+ stable version, 3.0, was released August, 2002.

+ <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#FILTER"

+> to
+ rewrite the content that is send to the client,
+ <TT

+HREF="actions-file.html#CLIENT-HEADER-FILTER"
+>client-header-filter</A
+></TT
+>
+ to rewrite headers that are send by the client, and
+ <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#SERVER-HEADER-FILTER"
+>server-header-filter</A
+></TT
+>
+ to rewrite headers that are send by the server.</P
+><P
+> <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> also supports two tagger actions:
+ <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#CLIENT-HEADER-TAGGER"
+>client-header-tagger</A
+></TT
+>
+ and
+ <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#SERVER-HEADER-TAGGER"
+>server-header-tagger</A
+></TT
+>.
+ Taggers and filters use the same syntax in the filter files, the difference
+ is that taggers don't modify the text they are filtering, but use a rewritten
+ version of the filtered text as tag. The tags can then be used to change the
+ applying actions through sections with <A
+HREF="actions-file.html#TAG-PATTERN"
+>tag-patterns</A
+>.</P
+><P
+> Multiple filter files can be defined through the <TT
+CLASS="LITERAL"
+> <A
+HREF="config.html#FILTERFILE"
+>filterfile</A
+></TT
+> config directive. The filters
+ as supplied by the developers are located in
+ <TT
+CLASS="FILENAME"
+>default.filter</TT
+>. It is recommended that any locally
+ defined or modified filters go in a separately defined file such as
+ <TT
+CLASS="FILENAME"
+>user.filter</TT
+>.
+ </P
+><P
+> Common tasks for content filters are to eliminate common annoyances in
+ HTML and JavaScript, such as pop-up windows,
+ exit consoles, crippled windows without navigation tools, the
+ infamous <BLINK> tag etc, to suppress images with certain
+ width and height attributes (standard banner sizes or web-bugs),
+ or just to have fun.</P
+><P
+> Enabled content filters are applied to any content whose
+ <SPAN
+CLASS="QUOTE"
+>"Content Type"</SPAN
+> header is recognised as a sign
+ of text-based content, with the exception of <TT
+CLASS="LITERAL"
+>text/plain</TT
+>.
+ Use the <A
+HREF="actions-file.html#FORCE-TEXT-MODE"
+>force-text-mode</A
+> action
+ to also filter other content.</P
+><P
+> Substitutions are made at the source level, so if you want to <SPAN
+CLASS="QUOTE"
+>"roll
+ your own"</SPAN
+> filters, you should first be familiar with HTML syntax,
+ and, of course, regular expressions.</P
+><P
+> Just like the <A
+HREF="actions-file.html"
+>actions files</A
+>, the
+ filter file is organized in sections, which are called <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>filters</I
+></SPAN
+>
+ here. Each filter consists of a heading line, that starts with one of the
+ <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>keywords</I
+></SPAN
+> <TT
+CLASS="LITERAL"
+>FILTER:</TT
+>,
+ <TT
+CLASS="LITERAL"
+>CLIENT-HEADER-FILTER:</TT
+> or <TT
+CLASS="LITERAL"
+>SERVER-HEADER-FILTER:</TT
+>
+ followed by the filter's <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>name</I
+></SPAN
+>, and a short (one line)
+ <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>description</I
+></SPAN
+> of what it does. Below that line
+ come the <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>jobs</I
+></SPAN
+>, i.e. lines that define the actual
+ text substitutions. By convention, the name of a filter
+ should describe what the filter <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>eliminates</I
+></SPAN
+>. The
+ comment is used in the <A
+HREF="http://config.privoxy.org/"
+TARGET="_top"
+>web-based
+ user interface</A
+>.</P
+><P
+> Once a filter called <TT
+CLASS="REPLACEABLE"
+><I
+>name</I
+></TT
+> has been defined
+ in the filter file, it can be invoked by using an action of the form
+ +<TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#FILTER"
+>filter</A
+>{<TT
+CLASS="REPLACEABLE"
+><I
+>name</I
+></TT
+>}</TT
+>
+ in any <A
+HREF="actions-file.html"
+>actions file</A
+>.</P
+><P
+> Filter definitions start with a header line that contains the filter
+ type, the filter name and the filter description.
+ A content filter header line for a filter called <SPAN
+CLASS="QUOTE"
+>"foo"</SPAN
+> could look
+ like this:</P
+><P
+> <TABLE
+BORDER="0"
+BGCOLOR="#E0E0E0"

+><TR
+><TD
+><PRE
+CLASS="SCREEN"
+>FILTER: foo Replace all "foo" with "bar"</PRE
+></TD
+></TR
+></TABLE
+></P
+><P
+> Below that line, and up to the next header line, come the jobs that
+ define what text replacements the filter executes. They are specified
+ in a syntax that imitates <A
+HREF="http://www.perl.org/"
+TARGET="_top"
+>Perl</A
+>'s
+ <TT
+CLASS="LITERAL"
+>s///</TT
+> operator. If you are familiar with Perl, you
+ will find this to be quite intuitive, and may want to look at the
+ PCRS documentation for the subtle differences to Perl behaviour. Most
+ notably, the non-standard option letter <TT
+CLASS="LITERAL"
+>U</TT
+> is supported,
+ which turns the default to ungreedy matching.</P

+></TD
+></TR
+></TABLE
+></P
+><P
+> Following the header line and a comment, you see the job. Note that it uses
+ <TT
+CLASS="LITERAL"
+>|</TT
+> as the delimiter instead of <TT
+CLASS="LITERAL"
+>/</TT
+>, because
+ the pattern contains a forward slash, which would otherwise have to be escaped
+ by a backslash (<TT
+CLASS="LITERAL"
+>\</TT
+>).</P
+><P
+> Now, let's examine the pattern: it starts with the text <TT
+CLASS="LITERAL"
+><script.*</TT
+>
+ enclosed in parentheses. Since the dot matches any character, and <TT
+CLASS="LITERAL"
+>*</TT
+>
+ means: <SPAN
+CLASS="QUOTE"
+>"Match an arbitrary number of the element left of myself"</SPAN
+>, this
+ matches <SPAN
+CLASS="QUOTE"
+>"<script"</SPAN
+>, followed by <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>any</I
+></SPAN
+> text, i.e.
+ it matches the whole page, from the start of the first <script> tag.</P
+><P
+> That's more than we want, but the pattern continues: <TT
+CLASS="LITERAL"
+>document\.referrer</TT
+>
+ matches only the exact string <SPAN
+CLASS="QUOTE"
+>"document.referrer"</SPAN
+>. The dot needed to
+ be <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>escaped</I
+></SPAN
+>, i.e. preceded by a backslash, to take away its
+ special meaning as a joker, and make it just a regular dot. So far, the meaning is:
+ Match from the start of the first <script> tag in a the page, up to, and including,
+ the text <SPAN
+CLASS="QUOTE"
+>"document.referrer"</SPAN
+>, if <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>both</I
+></SPAN
+> are present
+ in the page (and appear in that order).</P
+><P
+> But there's still more pattern to go. The next element, again enclosed in parentheses,
+ is <TT
+CLASS="LITERAL"
+>.*</script></TT
+>. You already know what <TT
+CLASS="LITERAL"
+>.*</TT
+>
+ means, so the whole pattern translates to: Match from the start of the first <script>
+ tag in a page to the end of the last <script> tag, provided that the text
+ <SPAN
+CLASS="QUOTE"
+>"document.referrer"</SPAN
+> appears somewhere in between.</P
+><P
+> This is still not the whole story, since we have ignored the options and the parentheses:
+ The portions of the page matched by sub-patterns that are enclosed in parentheses, will be
+ remembered and be available through the variables <TT
+CLASS="LITERAL"
+>$1, $2, ...</TT
+> in
+ the substitute. The <TT
+CLASS="LITERAL"
+>U</TT
+> option switches to ungreedy matching, which means
+ that the first <TT
+CLASS="LITERAL"
+>.*</TT
+> in the pattern will only <SPAN
+CLASS="QUOTE"
+>"eat up"</SPAN
+> all
+ text in between <SPAN
+CLASS="QUOTE"
+>"<script"</SPAN
+> and the <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>first</I
+></SPAN
+> occurrence
+ of <SPAN
+CLASS="QUOTE"
+>"document.referrer"</SPAN
+>, and that the second <TT
+CLASS="LITERAL"
+>.*</TT
+> will
+ only span the text up to the <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>first</I
+></SPAN
+> <SPAN
+CLASS="QUOTE"
+>"</script>"</SPAN
+>
+ tag. Furthermore, the <TT
+CLASS="LITERAL"
+>s</TT
+> option says that the match may span
+ multiple lines in the page, and the <TT
+CLASS="LITERAL"
+>g</TT
+> option again means that the
+ substitution is global.</P
+><P
+> So, to summarize, the pattern means: Match all scripts that contain the text
+ <SPAN
+CLASS="QUOTE"
+>"document.referrer"</SPAN
+>. Remember the parts of the script from
+ (and including) the start tag up to (and excluding) the string
+ <SPAN
+CLASS="QUOTE"
+>"document.referrer"</SPAN
+> as <TT
+CLASS="LITERAL"
+>$1</TT
+>, and the part following
+ that string, up to and including the closing tag, as <TT
+CLASS="LITERAL"
+>$2</TT
+>.</P
+><P
+> Now the pattern is deciphered, but wasn't this about substituting things? So
+ lets look at the substitute: <TT
+CLASS="LITERAL"
+>$1"Not Your Business!"$2</TT
+> is
+ easy to read: The text remembered as <TT
+CLASS="LITERAL"
+>$1</TT
+>, followed by
+ <TT
+CLASS="LITERAL"
+>"Not Your Business!"</TT
+> (<SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>including</I
+></SPAN
+>
+ the quotation marks!), followed by the text remembered as <TT
+CLASS="LITERAL"
+>$2</TT
+>.
+ This produces an exact copy of the original string, with the middle part
+ (the <SPAN
+CLASS="QUOTE"
+>"document.referrer"</SPAN
+>) replaced by <TT
+CLASS="LITERAL"
+>"Not Your
+ Business!"</TT
+>.</P
+><P
+> The whole job now reads: Replace <SPAN
+CLASS="QUOTE"
+>"document.referrer"</SPAN
+> by
+ <TT
+CLASS="LITERAL"
+>"Not Your Business!"</TT
+> wherever it appears inside a
+ <script> tag. Note that this job won't break JavaScript syntax,
+ since both the original and the replacement are syntactically valid
+ string objects. The script just won't have access to the referrer
+ information anymore.</P
+><P
+> We'll show you two other jobs from the JavaScript taming department, but
+ this time only point out the constructs of special interest:</P

+></TR
+></TABLE
+></P
+><P
+> <TT
+CLASS="LITERAL"
+>\s</TT
+> stands for whitespace characters (space, tab, newline,
+ carriage return, form feed), so that <TT
+CLASS="LITERAL"
+>\s*</TT
+> means: <SPAN
+CLASS="QUOTE"
+>"zero
+ or more whitespace"</SPAN
+>. The <TT
+CLASS="LITERAL"
+>?</TT
+> in <TT
+CLASS="LITERAL"
+>.*?</TT
+>
+ makes this matching of arbitrary text ungreedy. (Note that the <TT
+CLASS="LITERAL"
+>U</TT
+>
+ option is not set). The <TT
+CLASS="LITERAL"
+>['"]</TT
+> construct means: <SPAN
+CLASS="QUOTE"
+>"a single
+ <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>or</I
+></SPAN
+> a double quote"</SPAN
+>. Finally, <TT
+CLASS="LITERAL"
+>\1</TT
+> is
+ a back-reference to the first parenthesis just like <TT
+CLASS="LITERAL"
+>$1</TT
+> above,
+ with the difference that in the <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>pattern</I
+></SPAN
+>, a backslash indicates
+ a back-reference, whereas in the <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>substitute</I
+></SPAN
+>, it's the dollar.</P
+><P
+> So what does this job do? It replaces assignments of single- or double-quoted
+ strings to the <SPAN
+CLASS="QUOTE"
+>"window.status"</SPAN
+> object with a dummy assignment
+ (using a variable name that is hopefully odd enough not to conflict with
+ real variables in scripts). Thus, it catches many cases where e.g. pointless
+ descriptions are displayed in the status bar instead of the link target when
+ you move your mouse over links.</P

+>4.1. Quickstart to Ad Blocking</A
+></H2
+><P
+> Ad blocking is but one of <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+>
+ array of features. Many of these features are for the technically minded advanced
+ user. But, ad and banner blocking is surely common ground for everybody.</P
+><P
+>
+ This section will provide a quick summary of ad blocking so
+ you can get up to speed quickly without having to read the more extensive
+ information provided below, though this is highly recommended.</P
+><P
+> First a bit of a warning ... blocking ads is much like blocking SPAM: the
+ more aggressive you are about it, the more likely you are to block
+ things that were not intended. And the more likely that some things
+ may not work as intended. So there is a trade off here. If you want
+ extreme ad free browsing, be prepared to deal with more
+ <SPAN
+CLASS="QUOTE"
+>"problem"</SPAN
+> sites, and to spend more time adjusting the
+ configuration to solve these unintended consequences. In short, there is
+ not an easy way to eliminate <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>all</I
+></SPAN
+> ads. Either take
+ the easy way and settle for <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>most</I
+></SPAN
+> ads blocked with the
+ default configuration, or jump in and tweak it for your personal surfing
+ habits and preferences.</P
+><P
+> Secondly, a brief explanation of <SPAN
+CLASS="APPLICATION"
+>Privoxy's </SPAN
+>
+ <SPAN
+CLASS="QUOTE"
+>"actions"</SPAN
+>. <SPAN
+CLASS="QUOTE"
+>"Actions"</SPAN
+> in this context, are
+ the directives we use to tell <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> to perform
+ some task relating to HTTP transactions (i.e. web browsing). We tell
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> to take some <SPAN
+CLASS="QUOTE"
+>"action"</SPAN
+>. Each
+ action has a unique name and function. While there are many potential
+ <SPAN
+CLASS="APPLICATION"
+>actions</SPAN
+> in <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+>
+ arsenal, only a few are used for ad blocking. <A
+HREF="actions-file.html#ACTIONS"
+>Actions</A
+>, and <A
+HREF="actions-file.html"
+>action
+ configuration files</A
+>, are explained in depth below.</P
+><P
+> Actions are specified in <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+> configuration,
+ followed by one or more URLs to which the action should apply. URLs
+ can actually be URL type <A
+HREF="actions-file.html#AF-PATTERNS"
+>patterns</A
+> that use
+ wildcards so they can apply potentially to a range of similar URLs. The
+ actions, together with the URL patterns are called a section.</P
+><P
+> When you connect to a website, the full URL will either match one or more
+ of the sections as defined in <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+> configuration,
+ or not. If so, then <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> will perform the
+ respective actions. If not, then nothing special happens. Furthermore, web
+ pages may contain embedded, secondary URLs that your web browser will
+ use to load additional components of the page, as it parses the
+ original page's HTML content. An ad image for instance, is just an URL
+ embedded in the page somewhere. The image itself may be on the same server,
+ or a server somewhere else on the Internet. Complex web pages will have many
+ such embedded URLs. <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> can deal with each URL individually, so, for
+ instance, the main page text is not touched, but images from such-and-such
+ server are blocked.</P
+><P
+> The most important actions for basic ad blocking are: <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#BLOCK"
+>block</A
+></TT
+>, <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#HANDLE-AS-IMAGE"
+>handle-as-image</A
+></TT
+>,
+ <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#HANDLE-AS-EMPTY-DOCUMENT"
+>handle-as-empty-document</A
+></TT
+>,and
+ <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#SET-IMAGE-BLOCKER"
+>set-image-blocker</A
+></TT
+>:</P
+><P
+> <P
+></P
+><UL
+><LI
+><P
+> <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#BLOCK"
+>block</A
+></TT
+> - this is perhaps
+ the single most used action, and is particularly important for ad blocking.
+ This action stops any contact between your browser and any URL patterns
+ that match this action's configuration. It can be used for blocking ads,
+ but also anything that is determined to be unwanted. By itself, it simply
+ stops any communication with the remote server and sends
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>'s own built-in BLOCKED page instead to
+ let you now what has happened (with some exceptions, see below).
+ </P
+></LI
+><LI
+><P
+> <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#HANDLE-AS-IMAGE"
+>handle-as-image</A
+></TT
+> -
+ tells <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> to treat this URL as an image.
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+>'s default configuration already does this
+ for all common image types (e.g. GIF), but there are many situations where this
+ is not so easy to determine. So we'll force it in these cases. This is particularly
+ important for ad blocking, since only if we know that it's an image of
+ some kind, can we replace it with an image of our choosing, instead of the
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> BLOCKED page (which would only result in
+ a <SPAN
+CLASS="QUOTE"
+>"broken image"</SPAN
+> icon). There are some limitations to this
+ though. For instance, you can't just brute-force an image substitution for
+ an entire HTML page in most situations.
+ </P

+><P
+> <TT
+CLASS="LITERAL"
+><A
+HREF="actions-file.html#HANDLE-AS-EMPTY-DOCUMENT"
+>handle-as-empty-document</A
+></TT
+> -
+ sends an empty document instead of <SPAN
+CLASS="APPLICATION"
+>Privoxy's</SPAN
+>
+ normal BLOCKED HTML page. This is useful for file types that are neither
+ HTML nor images, such as blocking JavaScript files.

+> <TT

+>
+ <TT

+>blocks</A
+></TT
+>.
+ A <SPAN
+CLASS="QUOTE"
+>"block"</SPAN

+ are a way of filtering or modifying what is actually on the page. An example
+ filter usage: a text replacement of <SPAN
+CLASS="QUOTE"
+>"no-no"</SPAN
+> for
+ <SPAN
+CLASS="QUOTE"
+>"nasty-word"</SPAN
+>. That is a very simple example. This process can be
+ used for ad blocking, but it is more in the realm of advanced usage and has
+ some pitfalls to be wary off.</P
+><P
+> The quickest way to adjust any of these settings is with your browser through
+ the special <SPAN

+HREF="http://config.privoxy.org/show-status"
+TARGET="_top"

+ (shortcut: <A

+> Note that as of <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> 3.0.7 beta the
+ action editor is disabled by default. Check the
+ <A
+HREF="config.html#ENABLE-EDIT-ACTIONS"

+>"actions"</SPAN
+> file, and click
+ <SPAN
+CLASS="QUOTE"

+ local preferences in <TT
+CLASS="FILENAME"
+>user.action</TT
+> since this is not
+ meant to be overwritten during upgrades, and will over-ride the settings in
+ other files. Here you can insert new <SPAN

+ blocking or other purposes, and make other adjustments to the configuration.

+>.</P
+><P
+> The templates are basically normal HTML files, but with place-holders (called symbols
+ or exports), which <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> fills at run time. It
+ is possible to edit the templates with a normal text editor, should you want
+ to customize them. (<SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>Not recommended for the casual

+HREF="config.html#TEMPLDIR"
+>templdir</A
+>
+ to specify an alternate location, so your templates do not get overwritten

+> Note that just like in configuration files, lines starting
+ with <TT
+CLASS="LITERAL"
+>#</TT
+> are ignored when the templates are filled in.</P
+><P
+> The place-holders are of the form <TT
+CLASS="LITERAL"
+>@name@</TT
+>, and you will
+ find a list of available symbols, which vary from template to template,
+ in the comments at the start of each file. Note that these comments are not
+ always accurate, and that it's probably best to look at the existing HTML
+ code to find out which symbols are supported and what they are filled in with.</P
+><P
+> A special application of this substitution mechanism is to make whole
+ blocks of HTML code disappear when a specific symbol is set. We use this
+ for many purposes, one of them being to include the beta warning in all

+> When running in daemon mode, Privoxy doesn't log anything

+><P
+> The show-status page prints warnings about invalid directives

+> Fixed several justified (but harmless) compiler warnings,
+ mostly on 64 bit platforms.

+> The mingw32 version explicitly requests the default charset
+ to prevent display problems with some fonts available on more

+> The mingw32 version uses the Privoxy icon in the alt-tab

+ * static int debug = (LOG_LEVEL_FATAL | LOG_LEVEL_ERROR | LOG_LEVEL_INFO);
+ *
+ * Revision 1.91 2009/03/18 21:56:30 fabiankeil
+ * In init_error_log(), suppress the "(Re-)Opening logfile" message if
+ * we're still logging to stderr. This restores the "silent mode", but
+ * with LOG_LEVEL_INFO enabled, the show_version() info is written to
+ * the logfile as intended.
+ *
+ * Revision 1.90 2009/03/18 20:43:19 fabiankeil
+ * Don't enable LOG_LEVEL_INFO by default and don't apply the user's
+ * debug settings until the logfile has been opened (if there is one).
+ * Patch submitted by Roland in #2624120.
+ *
+ * Revision 1.89 2009/03/07 12:56:12 fabiankeil
+ * Add log_error() support for unsigned long long (%lld).
+ *
+ * Revision 1.88 2009/03/07 11:34:36 fabiankeil
+ * Omit timestamp and thread id in the mingw32 message box.
+ *
+ * Revision 1.87 2009/03/01 18:28:24 fabiankeil
+ * Help clang understand that we aren't dereferencing
+ * NULL pointers here.
+ *
+ * Revision 1.86 2009/02/09 21:21:15 fabiankeil
+ * Now that init_log_module() is called earlier, call show_version()
+ * later on from main() directly so it doesn't get called for --help
+ * or --version.
+ *
+ * Revision 1.85 2009/02/06 17:51:38 fabiankeil
+ * Be prepared if I break the log module initialization again.
+ *
+ * Revision 1.84 2008/12/14 15:46:22 fabiankeil
+ * Give crunched requests their own log level.
+ *
+ * Revision 1.83 2008/12/04 18:14:32 fabiankeil
+ * Fix some cparser warnings.
+ *
+ * Revision 1.82 2008/11/23 16:06:58 fabiankeil
+ * Update a log message I missed in 1.80.
+ *
+ * Revision 1.81 2008/11/23 15:59:27 fabiankeil
+ * - Update copyright range.
+ * - Remove stray line breaks in a log message
+ * nobody is supposed to see anyway.
+ *
+ * Revision 1.80 2008/11/23 15:49:49 fabiankeil
+ * In log_error(), don't surround the thread id with "Privoxy(" and ")".
+ *
+ * Revision 1.79 2008/10/20 17:09:25 fabiankeil
+ * Update init_error_log() description to match reality.
+ *
+ * Revision 1.78 2008/09/07 16:59:31 fabiankeil
+ * Update a comment to reflect that we
+ * have mutex support on mingw32 now.
+ *
+ * Revision 1.77 2008/09/07 12:43:44 fabiankeil
+ * Move the LogPutString() call in log_error() into the locked
+ * region so the Windows GUI log is consistent with the logfile.
+ *
+ * Revision 1.76 2008/09/07 12:35:05 fabiankeil
+ * Add mutex lock support for _WIN32.
+ *
+ * Revision 1.75 2008/09/04 08:13:58 fabiankeil
+ * Prepare for critical sections on Windows by adding a
+ * layer of indirection before the pthread mutex functions.
+ *
+ * Revision 1.74 2008/08/06 18:33:36 fabiankeil
+ * If the "close fd first" workaround doesn't work,
+ * the fatal error message will be lost, so we better
+ * explain the consequences while we still can.
+ *
+ * Revision 1.73 2008/08/04 19:06:55 fabiankeil
+ * Add a lame workaround for the "can't open an already open
+ * logfile on OS/2" problem reported by Maynard in #2028842
+ * and describe what a real solution would look like.
+ *
+ * Revision 1.72 2008/07/27 12:04:28 fabiankeil
+ * Fix a comment typo.
+ *
+ * Revision 1.71 2008/06/28 17:17:15 fabiankeil
+ * Remove another stray semicolon.
+ *
+ * Revision 1.70 2008/06/28 17:10:29 fabiankeil
+ * Remove stray semicolon in get_log_timestamp().
+ * Reported by Jochen Voss in #2005221.
+ *
+ * Revision 1.69 2008/05/30 15:55:25 fabiankeil
+ * Declare variable "debug" static and complain about its name.
+ *
+ * Revision 1.68 2008/04/27 16:50:46 fabiankeil
+ * Remove an incorrect assertion. The value of debug may change if
+ * the configuration is reloaded in another thread. While we could
+ * cache the initial value, the assertion doesn't seem worth it.
+ *
+ * Revision 1.67 2008/03/27 18:27:23 fabiankeil
+ * Remove kill-popups action.
+ *
+ * Revision 1.66 2008/01/31 15:38:14 fabiankeil
+ * - Make the logfp assertion more strict. As of 1.63, the "||" could
+ * have been an "&&", which means we can use two separate assertions
+ * and skip on of them on Windows.
+ * - Break a long commit message line in two.
+ *
+ * Revision 1.65 2008/01/31 14:44:33 fabiankeil
+ * Use (a != b) instead of !(a == b) so the sanity check looks less insane.
+ *
+ * Revision 1.64 2008/01/21 18:56:46 david__schmidt
+ * Swap #def from negative to positive, re-joined it so it didn't
+ * span an assertion (compilation failure on OS/2)
+ *
+ * Revision 1.63 2007/12/15 19:49:32 fabiankeil
+ * Stop overloading logfile to control the mingw32 log window as well.
+ * It's no longer necessary now that we disable all debug lines by default
+ * and at least one user perceived it as a regression (added in 1.55).
+ *
+ * Revision 1.62 2007/11/30 15:33:46 fabiankeil
+ * Unbreak LOG_LEVEL_FATAL. It wasn't fatal with logging disabled
+ * and on mingw32 fatal log messages didn't end up in the log file.
+ *
+ * Revision 1.61 2007/11/04 19:03:01 fabiankeil
+ * Fix another deadlock Hal spotted and that mysteriously didn't affect FreeBSD.
+ *
+ * Revision 1.60 2007/11/03 19:03:31 fabiankeil
+ * - Prevent the Windows GUI from showing the version two times in a row.
+ * - Stop using the imperative in the "(Re-)Open logfile" message.
+ * - Ditch the "Switching to daemon mode" message as the detection
+ * whether or not we're already in daemon mode doesn't actually work.
+ *
+ * Revision 1.59 2007/11/01 12:50:56 fabiankeil
+ * Here's looking at you, deadlock.
+ *
+ * Revision 1.58 2007/10/28 19:04:21 fabiankeil
+ * Don't mention daemon mode in "Logging disabled" message. Some
+ * platforms call it differently and it's not really relevant anyway.
+ *
+ * Revision 1.57 2007/10/27 13:02:26 fabiankeil
+ * Relocate daemon-mode-related log messages to make sure
+ * they aren't shown again in case of configuration reloads.
+ *
+ * Revision 1.56 2007/10/14 14:26:56 fabiankeil
+ * Remove the old log_error() version.
+ *
+ * Revision 1.55 2007/10/14 14:12:41 fabiankeil
+ * When in daemon mode, close stderr after the configuration file has been
+ * parsed the first time. If logfile isn't set, stop logging. Fixes BR#897436.
+ *
+ * Revision 1.54 2007/09/22 16:15:34 fabiankeil
+ * - Let it compile with pcc.
+ * - Move our includes below system includes to prevent macro conflicts.
+ *
+ * Revision 1.53 2007/08/05 13:53:14 fabiankeil
+ * #1763173 from Stefan Huehner: declare some more functions
+ * static and use void instead of empty parameter lists.
+ *
+ * Revision 1.52 2007/07/14 07:28:47 fabiankeil
+ * Add translation function for JB_ERR_FOO codes.
+ *
+ * Revision 1.51 2007/05/11 11:51:34 fabiankeil
+ * Fix a type mismatch warning.
+ *
+ * Revision 1.50 2007/04/11 10:55:44 fabiankeil
+ * Enforce some assertions that could be triggered
+ * on mingw32 and other systems where we use threads
+ * but no locks.
+ *
+ * Revision 1.49 2007/04/08 16:44:15 fabiankeil
+ * We need <sys/time.h> for gettimeofday(), not <time.h>.
+ *
+ * Revision 1.48 2007/03/31 13:33:28 fabiankeil
+ * Add alternative log_error() with timestamps
+ * that contain milliseconds and without using
+ * strcpy(), strcat() or sprintf().
+ *
+ * Revision 1.47 2006/11/28 15:25:15 fabiankeil
+ * Only unlink the pidfile if it's actually used.
+ *
+ * Revision 1.46 2006/11/13 19:05:51 fabiankeil
+ * Make pthread mutex locking more generic. Instead of
+ * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
+ * and use mutex locking unless there is an _r function
+ * available. Better safe than sorry.
+ *
+ * Fixes "./configure --disable-pthread" and should result
+ * in less threading-related problems on pthread-using platforms,
+ * but it still doesn't fix BR#1122404.
+ *
+ * Revision 1.45 2006/08/21 11:15:54 david__schmidt
+ * MS Visual C++ build updates
+ *
+ * Revision 1.44 2006/08/18 16:03:16 david__schmidt

+ *
+ * Revision 1.42 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)

+ *
+ * Revision 1.40.2.4 2005/04/03 20:10:50 david__schmidt
+ * Thanks to Jindrich Makovicka for a race condition fix for the log
+ * file. The race condition remains for non-pthread implementations.
+ * Reference patch #1175720.
+ *
+ * Revision 1.40.2.3 2003/03/07 03:41:04 david__schmidt
+ * Wrapping all *_r functions (the non-_r versions of them) with mutex
+ * semaphores for OSX. Hopefully this will take care of all of those pesky
+ * crash reports.
+ *
+ * Revision 1.40.2.2 2002/09/28 00:30:57 david__schmidt
+ * Update error logging to give sane values for thread IDs on Mach kernels.
+ * It's still a hack, but at least it looks farily normal. We print the
+ * absolute value of the first 4 bytes of the pthread_t modded with 1000.
+ *
+ * Revision 1.40.2.1 2002/09/25 12:47:42 oes

+ * Revision 1.39 2002/04/03 17:15:27 gliptak
+ * zero padding thread ids in log

+ * Revision 1.38 2002/03/31 17:18:59 jongfoster
+ * Win32 only: Enabling STRICT to fix a VC++ compile warning.
+ *

+ * More compiler warning message maintenance
+ *
+ * Revision 1.36 2002/03/26 22:29:54 swa

+ * Fix big memory leak.
+ *
+ * Revision 1.25 2002/01/09 14:32:08 oes
+ * Added support for gmtime_r and localtime_r.
+ *
+ * Revision 1.24 2001/12/30 14:07:32 steudten
+ * - Add signal handling (unix)
+ * - Add SIGHUP handler (unix)
+ * - Add creation of pidfile (unix)

+ * actionsfile and configfile.
+ * Special handling for CLF added.
+ *

+ * Add time+date to log files.
+ *
+ * Revision 1.21 2001/10/25 03:40:47 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.20 2001/09/16 23:04:34 jongfoster
+ * Fixing a warning
+ *
+ * Revision 1.19 2001/09/13 20:08:06 jongfoster

+ * Revision 1.18 2001/09/10 11:27:24 oes
+ * Declaration of w32_socket_strerr now conditional

+ * Removed unused variable; Fixed sprintf format
+ *
+ * Revision 1.16 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.15 2001/07/29 17:41:10 jongfoster
+ * Now prints thread ID for each message (pthreads only)
+ *
+ * Revision 1.14 2001/07/19 19:03:48 haroon
+ * - Added case for LOG_LEVEL_POPUPS
+ *
+ * Revision 1.13 2001/07/13 13:58:58 oes
+ * - Added case for LOG_LEVEL_DEANIMATE
+ * - Removed all #ifdef PCRS
+ *
+ * Revision 1.12 2001/06/09 10:55:28 jongfoster
+ * Changing BUFSIZ ==> BUFFER_SIZE
+ *
+ * Revision 1.11 2001/06/01 18:14:49 jongfoster
+ * Changing the calls to strerr() to check HAVE_STRERR (which is defined
+ * in config.h if appropriate) rather than the NO_STRERR macro.
+ *
+ * Revision 1.10 2001/05/29 11:52:21 oes
+ * Conditional compilation of w32_socket_error
+ *
+ * Revision 1.9 2001/05/28 16:15:17 jongfoster
+ * Improved reporting of errors under Win32.
+ *
+ * Revision 1.8 2001/05/26 17:25:14 jongfoster
+ * Added support for CLF (Common Log Format) and fixed LOG_LEVEL_LOG
+ *
+ * Revision 1.7 2001/05/26 15:21:28 jongfoster
+ * Activity animation in Win32 GUI now works even if debug==0
+ *
+ * Revision 1.6 2001/05/25 21:55:08 jongfoster
+ * Now cleans up properly on FATAL (removes taskbar icon etc)
+ *
+ * Revision 1.5 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.4 2001/05/21 19:32:54 jongfoster
+ * Added another #ifdef _WIN_CONSOLE
+ *
+ * Revision 1.3 2001/05/20 01:11:40 jongfoster
+ * Added support for LOG_LEVEL_FATAL
+ * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
+ * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
+ *
+ * Revision 1.2 2001/05/17 22:42:01 oes
+ * - Cleaned CRLF's from the sources and related files
+ * - Repaired logging for REF and FRC
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:51 oes
+ * Initial import of version 2.9.3 source tree
+ *

+ * or --version.
+ *
+ * Revision 1.21 2008/12/14 15:46:22 fabiankeil
+ * Give crunched requests their own log level.

+ * Remove kill-popups action.
+ *
+ * Revision 1.19 2007/10/14 14:12:41 fabiankeil
+ * When in daemon mode, close stderr after the configuration file has been
+ * parsed the first time. If logfile isn't set, stop logging. Fixes BR#897436.
+ *
+ * Revision 1.18 2007/07/14 07:28:47 fabiankeil
+ * Add translation function for JB_ERR_FOO codes.
+ *
+ * Revision 1.17 2007/03/31 13:33:28 fabiankeil
+ * Add alternative log_error() with timestamps

+ * strcpy(), strcat() or sprintf().
+ *
+ * Revision 1.16 2006/11/28 15:29:50 fabiankeil
+ * Define LOG_LEVEL_REDIRECTS independently of
+ * FEATURE_FAST_REDIRECTS. It is used by redirect{}
+ * as well.
+ *
+ * Revision 1.15 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.13.2.1 2002/08/05 17:57:06 oes
+ * Cosmetic change
+ *
+ * Revision 1.13 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * Revision 1.12 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.11 2002/03/06 23:02:57 jongfoster
+ * Removing tabs
+ *
+ * Revision 1.10 2001/09/13 20:08:06 jongfoster
+ * Adding support for LOG_LEVEL_CGI
+ *
+ * Revision 1.9 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.8 2001/07/29 18:43:08 jongfoster
+ * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
+ * ANSI C rules.
+ *
+ * Revision 1.7 2001/07/19 19:02:53 haroon
+ * Added define for LOG_LEVEL_POPUPS
+ *
+ * Revision 1.6 2001/07/13 13:59:22 oes
+ * - Added LOG_LEVEL_DEANIMATE
+ * - Changed LOG_LEVEL_CLF
+ * - Removed all #ifdef PCRS
+ *
+ * Revision 1.5 2001/05/26 17:25:14 jongfoster
+ * Added support for CLF (Common Log Format) and fixed LOG_LEVEL_LOG
+ *
+ * Revision 1.4 2001/05/25 21:56:06 jongfoster
+ * Added FIXME comment to (broken) LOG_LEVEL_LOG
+ *
+ * Revision 1.3 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.2 2001/05/20 01:11:40 jongfoster
+ * Added support for LOG_LEVEL_FATAL
+ * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
+ * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:51 oes
+ * Initial import of version 2.9.3 source tree

+ *
+ * Revision 1.107 2008/05/04 17:52:56 fabiankeil
+ * Adjust parse_http_url() call to new prototype.
+ *
+ * Revision 1.106 2008/05/03 16:40:44 fabiankeil
+ * Change content_filters_enabled()'s parameter from
+ * csp->action to action so it can be also used in the

+ * loaded, as that's somewhat besides the point.
+ *

+ * Remove kill-popups action.
+ *
+ * Revision 1.103 2008/03/06 16:33:45 fabiankeil
+ * If limit-connect isn't used, don't limit CONNECT requests to port 443.
+ *
+ * Revision 1.102 2008/03/01 14:00:44 fabiankeil
+ * Let the block action take the reason for the block
+ * as argument and show it on the "blocked" page.
+ *
+ * Revision 1.101 2008/02/23 16:57:12 fabiankeil
+ * Rename url_actions() to get_url_actions() and let it
+ * use the standard parameter ordering.
+ *
+ * Revision 1.100 2008/02/23 16:33:43 fabiankeil
+ * Let forward_url() use the standard parameter ordering
+ * and mark its second parameter immutable.
+ *
+ * Revision 1.99 2008/02/03 13:57:58 fabiankeil
+ * Add SOCKS5 support for forward-override{}.
+ *
+ * Revision 1.98 2008/01/04 17:43:45 fabiankeil
+ * Improve the warning messages that get logged if the action files
+ * "enable" filters but no filters of that type have been loaded.
+ *
+ * Revision 1.97 2007/11/30 15:37:03 fabiankeil
+ * Use freez instead of free.
+ *
+ * Revision 1.96 2007/10/19 16:53:28 fabiankeil
+ * Add helper function to check if any content filters are enabled.
+ *
+ * Revision 1.95 2007/10/17 19:31:20 fabiankeil
+ * Omitting the zero chunk that ends the chunk transfer encoding seems
+ * to be the new black. Log the problem and continue filtering anyway.
+ *
+ * Revision 1.94 2007/09/29 13:20:20 fabiankeil
+ * Remove two redundant and one useless log messages.
+ *
+ * Revision 1.93 2007/09/29 10:21:16 fabiankeil
+ * - Move get_filter_function() from jcc.c to filters.c
+ * so the filter functions can be static.
+ * - Don't bother filtering body-less responses.
+ *
+ * Revision 1.92 2007/09/28 16:38:55 fabiankeil
+ * - Execute content filters through execute_content_filter().
+ * - Add prepare_for_filtering() so filter functions don't have to
+ * care about de-chunking and decompression. As a side effect this enables
+ * decompression for gif_deanimate_response() and jpeg_inspect_response().
+ * - Change remove_chunked_transfer_coding()'s return type to jb_err.
+ * Some clowns feel like chunking empty responses in which case
+ * (size == 0) is valid but previously would be interpreted as error.
+ *
+ * Revision 1.91 2007/09/02 15:31:20 fabiankeil
+ * Move match_portlist() from filter.c to urlmatch.c.
+ * It's used for url matching, not for filtering.
+ *
+ * Revision 1.90 2007/09/02 12:44:17 fabiankeil
+ * Remove newline at the end of a log_error() message.
+ *
+ * Revision 1.89 2007/08/05 13:42:23 fabiankeil
+ * #1763173 from Stefan Huehner: declare some more functions static.
+ *
+ * Revision 1.88 2007/06/01 16:41:11 fabiankeil
+ * Add forward-override{} to change the forwarding settings through
+ * action sections. This is mainly interesting to forward different
+ * clients differently (for example based on User-Agent or request
+ * origin).
+ *
+ * Revision 1.87 2007/04/30 15:53:10 fabiankeil
+ * Make sure filters with dynamic jobs actually use them.
+ *
+ * Revision 1.86 2007/04/30 15:03:28 fabiankeil
+ * - Introduce dynamic pcrs jobs that can resolve variables.
+ * - Don't run redirect functions more than once,
+ * unless they are activated more than once.
+ *
+ * Revision 1.85 2007/03/21 12:24:47 fabiankeil
+ * - Log the content size after decompression in decompress_iob()
+ * instead of pcrs_filter_response().
+ *
+ * Revision 1.84 2007/03/20 15:16:34 fabiankeil
+ * Use dedicated header filter actions instead of abusing "filter".
+ * Replace "filter-client-headers" and "filter-client-headers"
+ * with "server-header-filter" and "client-header-filter".
+ *
+ * Revision 1.83 2007/03/17 15:20:05 fabiankeil
+ * New config option: enforce-blocks.
+ *
+ * Revision 1.82 2007/03/13 11:28:43 fabiankeil
+ * - Fix port handling in acl_addr() and use a temporary acl spec
+ * copy so error messages don't contain a truncated version.
+ * - Log size of iob before and after decompression.
+ *
+ * Revision 1.81 2007/03/05 14:40:53 fabiankeil
+ * - Cosmetical changes for LOG_LEVEL_RE_FILTER messages.
+ * - Hide the "Go there anyway" link for blocked CONNECT
+ * requests where going there anyway doesn't work anyway.
+ *
+ * Revision 1.80 2007/02/07 10:55:20 fabiankeil
+ * - Save the reason for generating http_responses.
+ * - Block (+block) with status code 403 instead of 404.
+ * - Use a different kludge to remember a failed decompression.
+ *
+ * Revision 1.79 2007/01/31 16:21:38 fabiankeil
+ * Search for Max-Forwards headers case-insensitive,

+ * Add the ability to check jpeg images for invalid

+ * Revision 1.45 2002/03/08 16:47:50 oes
+ * Added choice beween GIF and PNG built-in images

+ * Revision 1.44 2002/03/07 03:49:31 oes
+ * - Fixed compiler warnings etc
+ * - Changed built-in images from GIF to PNG

+ * - Added a 4x4 pattern PNG which is less intrusive

+ *
+ * Revision 1.43 2002/01/22 23:51:59 jongfoster
+ * Replacing strsav() with the safer string_append().
+ *
+ * Adding missing html_encode() to error message generators. Where encoded
+ * and unencoded versions of a string were provided, removing the unencoded
+ * one.
+ *
+ * Revision 1.42 2002/01/17 21:00:32 jongfoster
+ * Moving all our URL and URL pattern parsing code to urlmatch.c.
+ *
+ * Using a single, simple url_match(pattern,url) function - rather than
+ * the 3-line match routine which was repeated all over the place.
+ *
+ * Renaming free_url to free_url_spec, since it frees a struct url_spec.
+ *
+ * Using parse_http_url() to parse URLs without faking a HTTP
+ * request line for parse_http_request().
+ *
+ * Revision 1.41 2001/11/13 00:14:07 jongfoster
+ * Fixing stupid bug now I've figured out what || means.
+ * (It always returns 0 or 1, not one of it's paramaters.)
+ *
+ * Revision 1.40 2001/10/26 17:37:55 oes
+ * - Re-enabled Netscape 200/404 bug workaround in block_url():
+ * - Removed OS/2 special case
+ * - Made block_url() independant from sed() having been run
+ * - Made trust_url independant from sed() having been run
+ * - Made is_imageurl independant from sed() having been run.
+ * It now checks User-Agent: and Accept: by itself.
+ *
+ *
+ * Revision 1.39 2001/10/25 03:40:48 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.38 2001/10/23 21:32:33 jongfoster
+ * Adding error-checking to selected functions
+ *
+ * Revision 1.37 2001/10/22 15:33:56 david__schmidt
+ * Special-cased OS/2 out of the Netscape-abort-on-404-in-js problem in
+ * filters.c. Added a FIXME in front of the offending code. I'll gladly
+ * put in a better/more robust fix for all parties if one is presented...
+ * It seems that just returning 200 instead of 404 would pretty much fix
+ * it for everyone, but I don't know all the history of the problem.
+ *
+ * Revision 1.36 2001/10/10 16:44:16 oes
+ * Added match_portlist function
+ *
+ * Revision 1.35 2001/10/07 15:41:23 oes
+ * Replaced 6 boolean members of csp with one bitmap (csp->flags)
+ *
+ * New function remove_chunked_transfer_coding that strips chunked
+ * transfer coding to plain and is called by pcrs_filter_response
+ * and gif_deanimate_response if neccessary
+ *
+ * Improved handling of zero-change re_filter runs
+ *
+ * pcrs_filter_response and gif_deanimate_response now remove
+ * chunked transfer codeing before processing the body.
+ *
+ * Revision 1.34 2001/09/20 15:49:36 steudten
+ *
+ * Fix BUG: Change int size to size_t size in pcrs_filter_response().
+ * See cgi.c fill_template().
+ *
+ * Revision 1.33 2001/09/16 17:05:14 jongfoster
+ * Removing unused #include showarg.h
+ *
+ * Revision 1.32 2001/09/16 13:21:27 jongfoster
+ * Changes to use new list functions.
+ *
+ * Revision 1.31 2001/09/16 11:38:02 jongfoster
+ * Splitting fill_template() into 2 functions:
+ * template_load() loads the file
+ * template_fill() performs the PCRS regexps.
+ * This is because the CGI edit interface has a "table row"
+ * template which is used many times in the page - this
+ * change means it's only loaded from disk once.
+ *
+ * Revision 1.30 2001/09/16 11:00:10 jongfoster
+ * New function alloc_http_response, for symmetry with free_http_response
+ *
+ * Revision 1.29 2001/09/13 23:32:40 jongfoster
+ * Moving image data to cgi.c rather than cgi.h
+ * Fixing a GPF under Win32 (and any other OS that protects global
+ * constants from being written to).
+ *
+ * Revision 1.28 2001/09/10 10:18:51 oes
+ * Silenced compiler warnings
+ *
+ * Revision 1.27 2001/08/05 16:06:20 jongfoster
+ * Modifiying "struct map" so that there are now separate header and
+ * "map_entry" structures. This means that functions which modify a
+ * map no longer need to return a pointer to the modified map.
+ * Also, it no longer reverses the order of the entries (which may be
+ * important with some advanced template substitutions).
+ *
+ * Revision 1.26 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.25 2001/07/26 10:09:46 oes
+ * Made browser detection a little less naive
+ *
+ * Revision 1.24 2001/07/25 17:22:51 oes
+ * Added workaround for Netscape bug that prevents display of page when loading a component fails.
+ *
+ * Revision 1.23 2001/07/23 13:40:12 oes
+ * Fixed bug that caused document body to be dropped when pcrs joblist was empty.
+ *
+ * Revision 1.22 2001/07/18 12:29:34 oes
+ * - Made gif_deanimate_response respect
+ * csp->action->string[ACTION_STRING_DEANIMATE]
+ * - Logging cosmetics
+ *
+ * Revision 1.21 2001/07/13 13:59:53 oes
+ * - Introduced gif_deanimate_response which shares the
+ * generic content modification interface of pcrs_filter_response
+ * and acts as a wrapper to deanimate.c:gif_deanimate()
+ * - Renamed re_process_buffer to pcrs_filter_response
+ * - pcrs_filter_response now returns NULL on failiure
+ * - Removed all #ifdef PCRS
+ *
+ * Revision 1.20 2001/07/01 17:01:04 oes
+ * Added comments and missing return statement in is_untrusted_url()
+ *
+ * Revision 1.19 2001/06/29 21:45:41 oes
+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.18 2001/06/29 13:27:38 oes
+ * - Cleaned up, renamed and reorderd functions
+ * and improved comments
+ *
+ * - block_url:
+ * - Ported to CGI platform. Now delivers
+ * http_response or NULL
+ * - Unified HTML and GIF generation (moved image detection
+ * and GIF generation here from jcc.c:chat())
+ * - Fixed HTTP status to:
+ * - 403 (Forbidden) for the "blocked" HTML message
+ * - 200 (OK) for GIF answers
+ * - 302 (Redirect) for redirect to GIF
+ *
+ * - trust_url:
+ * - Ported to CGI platform. Now delivers
+ * http_response or NULL
+ * - Separated detection of untrusted URL into
+ * (bool)is_untrusted_url
+ * - Added enforcement of untrusted requests
+ *
+ * - Moved redirect_url() from cgi.c to here
+ * and ported it to the CGI platform
+ *
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.17 2001/06/09 10:55:28 jongfoster
+ * Changing BUFSIZ ==> BUFFER_SIZE
+ *
+ * Revision 1.16 2001/06/07 23:10:26 jongfoster
+ * Allowing unanchored domain patterns to back off and retry
+ * if they partially match. Optimized right-anchored patterns.
+ * Moving ACL and forward files into config file.
+ * Replacing struct gateway with struct forward_spec
+ *
+ * Revision 1.15 2001/06/03 19:12:00 oes
+ * extracted-CGI relevant stuff
+ *
+ * Revision 1.14 2001/06/01 10:30:55 oes
+ * Added optional left-anchoring to domaincmp
+ *
+ * Revision 1.13 2001/05/31 21:21:30 jongfoster
+ * Permissionsfile / actions file changes:
+ * - Changed "permission" to "action" throughout
+ * - changes to file format to allow string parameters
+ * - Moved helper functions to actions.c
+ *
+ * Revision 1.12 2001/05/31 17:35:20 oes
+ *
+ * - Enhanced domain part globbing with infix and prefix asterisk
+ * matching and optional unanchored operation
+ *
+ * Revision 1.11 2001/05/29 11:53:23 oes
+ * "See why" link added to "blocked" page
+ *
+ * Revision 1.10 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.9 2001/05/27 22:17:04 oes
+ *
+ * - re_process_buffer no longer writes the modified buffer
+ * to the client, which was very ugly. It now returns the
+ * buffer, which it is then written by chat.
+ *
+ * - content_length now adjusts the Content-Length: header
+ * for modified documents rather than crunch()ing it.
+ * (Length info in csp->content_length, which is 0 for
+ * unmodified documents)
+ *
+ * - For this to work, sed() is called twice when filtering.
+ *
+ * Revision 1.8 2001/05/26 17:13:28 jongfoster
+ * Filled in a function comment.
+ *
+ * Revision 1.7 2001/05/26 15:26:15 jongfoster
+ * ACL feature now provides more security by immediately dropping
+ * connections from untrusted hosts.
+ *
+ * Revision 1.6 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.5 2001/05/25 22:34:30 jongfoster
+ * Hard tabs->Spaces
+ *
+ * Revision 1.4 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.3 2001/05/20 16:44:47 jongfoster
+ * Removing last hardcoded Junkbusters.com URLs.
+ *
+ * Revision 1.2 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:52 oes
+ * Initial import of version 2.9.3 source tree

+ *
+ * Revisions :
+ * $Log: filters.h,v $
+ * Revision 1.36 2008/05/21 15:35:08 fabiankeil
+ * - Mark csp as immutable for block_acl().
+ * - Remove an obsolete complaint about filter_popups().
+ *
+ * Revision 1.35 2008/05/03 16:40:45 fabiankeil
+ * Change content_filters_enabled()'s parameter from
+ * csp->action to action so it can be also used in the
+ * CGI code. Don't bother checking if there are filters
+ * loaded, as that's somewhat besides the point.
+ *
+ * Revision 1.34 2008/03/02 12:25:25 fabiankeil
+ * Also use shiny new connect_port_is_forbidden() in jcc.c.
+ *
+ * Revision 1.33 2008/02/23 16:57:12 fabiankeil
+ * Rename url_actions() to get_url_actions() and let it
+ * use the standard parameter ordering.
+ *
+ * Revision 1.32 2008/02/23 16:33:43 fabiankeil
+ * Let forward_url() use the standard parameter ordering
+ * and mark its second parameter immutable.
+ *
+ * Revision 1.31 2007/10/19 16:53:28 fabiankeil
+ * Add helper function to check if any content filters are enabled.
+ *
+ * Revision 1.30 2007/09/29 10:21:16 fabiankeil
+ * - Move get_filter_function() from jcc.c to filters.c
+ * so the filter functions can be static.
+ * - Don't bother filtering body-less responses.
+ *
+ * Revision 1.29 2007/09/28 16:38:55 fabiankeil
+ * - Execute content filters through execute_content_filter().
+ * - Add prepare_for_filtering() so filter functions don't have to
+ * care about de-chunking and decompression. As a side effect this enables
+ * decompression for gif_deanimate_response() and jpeg_inspect_response().
+ * - Change remove_chunked_transfer_coding()'s return type to jb_err.
+ * Some clowns feel like chunking empty responses in which case
+ * (size == 0) is valid but previously would be interpreted as error.
+ *
+ * Revision 1.28 2007/09/02 15:31:20 fabiankeil
+ * Move match_portlist() from filter.c to urlmatch.c.
+ * It's used for url matching, not for filtering.
+ *
+ * Revision 1.27 2007/04/30 15:02:18 fabiankeil
+ * Introduce dynamic pcrs jobs that can resolve variables.
+ *
+ * Revision 1.26 2007/03/13 11:28:43 fabiankeil
+ * - Fix port handling in acl_addr() and use a temporary acl spec
+ * copy so error messages don't contain a truncated version.
+ * - Log size of iob before and after decompression.
+ *
+ * Revision 1.25 2007/01/12 15:36:44 fabiankeil
+ * Mark *csp as immutable for is_untrusted_url()
+ * and is_imageurl(). Closes FR 1237736.
+ *
+ * Revision 1.24 2006/12/29 18:30:46 fabiankeil
+ * Fixed gcc43 conversion warnings,
+ * changed sprintf calls to snprintf.
+ *
+ * Revision 1.23 2006/11/28 15:19:43 fabiankeil
+ * Implemented +redirect{s@foo@bar@} to generate
+ * a redirect based on a rewritten version of the
+ * original URL.
+ *
+ * Revision 1.22 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.20.2.2 2004/10/03 12:53:32 david__schmidt
+ * Add the ability to check jpeg images for invalid
+ * lengths of comment blocks. Defensive strategy
+ * against the exploit:
+ * Microsoft Security Bulletin MS04-028
+ * Buffer Overrun in JPEG Processing (GDI+) Could
+ * Allow Code Execution (833987)
+ * Enabled with +inspect-jpegs in actions files.
+ *
+ * Revision 1.20.2.1 2002/09/25 14:51:51 oes
+ * Added basic support for OPTIONS and TRACE HTTP methods:
+ * New function direct_response which handles OPTIONS and
+ * TRACE requests whose Max-Forwards header field is zero.
+ *
+ * Revision 1.20 2002/04/02 14:56:16 oes
+ * Bugfix: is_untrusted_url() and trust_url() now depend on FEATURE_TRUST, not FEATURE_COOKIE_JAR
+ *
+ * Revision 1.19 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * Revision 1.18 2002/03/25 22:12:45 oes

+ *
+ * Revision 1.14 2001/10/07 15:41:40 oes
+ * Added prototype for remove_chunked_transfer_coding
+ *
+ * Revision 1.13 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.12 2001/07/29 19:01:11 jongfoster
+ * Changed _FILENAME_H to FILENAME_H_INCLUDED.
+ * Added forward declarations for needed structures.
+ *
+ * Revision 1.11 2001/07/13 14:00:18 oes
+ * - Introduced gif_deanimate_response
+ * - Renamed re_process_buffer to pcrs_filter_response
+ * - Removed all #ifdef PCRS
+ *
+ * Revision 1.10 2001/06/29 13:29:01 oes
+ * Cleaned up and updated to reflect the changesin
+ * filters.c
+ *
+ * Revision 1.9 2001/06/07 23:10:53 jongfoster
+ * Replacing struct gateway with struct forward_spec
+ *
+ * Revision 1.8 2001/06/03 19:12:00 oes
+ * extracted-CGI relevant stuff
+ *
+ * Revision 1.7 2001/05/31 21:21:30 jongfoster
+ * Permissionsfile / actions file changes:
+ * - Changed "permission" to "action" throughout
+ * - changes to file format to allow string parameters
+ * - Moved helper functions to actions.c
+ *
+ * Revision 1.6 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.5 2001/05/27 22:17:04 oes
+ *
+ * - re_process_buffer no longer writes the modified buffer
+ * to the client, which was very ugly. It now returns the
+ * buffer, which it is then written by chat.
+ *
+ * - content_length now adjusts the Content-Length: header
+ * for modified documents rather than crunch()ing it.
+ * (Length info in csp->content_length, which is 0 for
+ * unmodified documents)
+ *
+ * - For this to work, sed() is called twice when filtering.
+ *
+ * Revision 1.4 2001/05/26 15:26:15 jongfoster
+ * ACL feature now provides more security by immediately dropping
+ * connections from untrusted hosts.
+ *
+ * Revision 1.3 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.2 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:52 oes
+ * Initial import of version 2.9.3 source tree

+ * Revision 1.38 2008/10/24 17:33:00 fabiankeil
+ * - Tone the "keep-alive support is experimental" warning

+ * - Only show the "ndef HAVE_POLL" warning once on start-up.
+ *
+ * Revision 1.37 2008/10/23 17:40:53 fabiankeil
+ * Fix forget_connection() and mark_connection_unused(),

+ *
+ * Revision 1.36 2008/10/18 19:49:15 fabiankeil
+ * - Factor close_unusable_connections() out of

+ *
+ * Revision 1.30 2008/10/13 17:31:03 fabiankeil
+ * If a remembered connection is no longer usable and

+ *
+ * Revision 1.29 2008/10/11 16:59:41 fabiankeil
+ * Add missing dots for two log messages.
+ *
+ * Revision 1.28 2008/10/09 18:21:41 fabiankeil

+ * Fix typo in macro name.
+ *
+ * Revision 1.25 2008/02/07 18:09:46 fabiankeil
+ * In socks5_connect:
+ * - make the buffers quite a bit smaller.
+ * - properly report "socks5 server unreachable" failures.
+ * - let strncpy() use the whole buffer. Using a length of 0xffu wasn't actually
+ * wrong, but requires too much thinking as it doesn't depend on the buffer size.
+ * - log a message if the socks5 server sends more data than expected.
+ * - add some assertions and comments.
+ *
+ * Revision 1.24 2008/02/04 14:56:29 fabiankeil

+ * Revision 1.23 2008/02/04 13:11:35 fabiankeil
+ * Remember the cause of the SOCKS5 error for the CGI message.
+ *
+ * Revision 1.22 2008/02/03 13:46:15 fabiankeil
+ * Add SOCKS5 support. Patch #1862863 by Eric M. Hopper with minor changes.
+ *
+ * Revision 1.21 2007/07/28 12:30:03 fabiankeil
+ * Modified patch from Song Weijia (#1762559) to
+ * fix socks requests on big-endian platforms.
+ *
+ * Revision 1.20 2007/05/14 10:23:48 fabiankeil
+ * - Use strlcpy() instead of strcpy().
+ * - Use the same buffer for socks requests and socks responses.
+ * - Fix bogus warning about web_server_addr being used uninitialized.
+ *
+ * Revision 1.19 2007/01/25 14:09:45 fabiankeil
+ * - Save errors in socks4_connect() to csp->error_message.
+ * - Silence some gcc43 warnings, hopefully the right way.

+ * Killing warnings
+ *
+ * Revision 1.12 2002/03/09 20:03:52 jongfoster
+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.11 2002/03/08 17:46:04 jongfoster

+ * Revision 1.10 2002/03/07 03:50:19 oes
+ * - Improved handling of failed DNS lookups
+ * - Fixed compiler warnings
+ *
+ * Revision 1.9 2001/10/25 03:40:48 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.

+ * task of deciding whether to connect to the web server or HTTP
+ * proxy.
+ * Replacing struct gateway with struct forward_spec
+ * Fixing bug with SOCKS4A and HTTP proxy server in combination.
+ * It was a bug which led to the connection being made to the web
+ * server rather than the HTTP proxy, and also a buffer overrun.

+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.3 2001/07/29 18:58:15 jongfoster
+ * Removing nested #includes, adding forward declarations for needed
+ * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.

+ *
+ * Revisions :
+ * $Log: jbsockets.c,v $
+ * Revision 1.50 2008/12/20 14:53:55 fabiankeil
+ * Add config option socket-timeout to control the time
+ * Privoxy waits for data to arrive on a socket. Useful
+ * in case of stale ssh tunnels or when fuzz-testing.
+ *
+ * Revision 1.49 2008/11/10 17:03:57 fabiankeil
+ * Fix a gcc44 warning and remove a now-obsolete cast.
+ *
+ * Revision 1.48 2008/09/04 08:13:58 fabiankeil
+ * Prepare for critical sections on Windows by adding a
+ * layer of indirection before the pthread mutex functions.
+ *
+ * Revision 1.47 2008/03/26 18:07:07 fabiankeil
+ * Add hostname directive. Closes PR#1918189.
+ *
+ * Revision 1.46 2008/03/21 11:13:57 fabiankeil
+ * Only gather host information if it's actually needed.
+ * Also move the code out of accept_connection() so it's less likely
+ * to delay other incoming connections if the host is misconfigured.
+ *
+ * Revision 1.45 2007/09/30 16:59:22 fabiankeil
+ * Set the maximum listen() backlog to 128. Apparently SOMAXCONN is
+ * neither high enough, nor a hard limit on mingw32. Again for BR#1795281.
+ *
+ * Revision 1.44 2007/09/15 13:01:31 fabiankeil
+ * Increase listen() backlog to SOMAXCONN (or 128) to decrease
+ * chances of dropped connections under load. Problem reported
+ * and fix suggested by nobody in BR#1795281.
+ *
+ * Revision 1.43 2007/06/01 18:16:36 fabiankeil
+ * Use the same mutex for gethostbyname() and gethostbyaddr() to prevent
+ * deadlocks and crashes on OpenBSD and possibly other OS with neither
+ * gethostbyname_r() nor gethostaddr_r(). Closes BR#1729174.
+ * Thanks to Ralf Horstmann for report and solution.
+ *
+ * Revision 1.42 2007/04/01 17:37:07 fabiankeil
+ * - Add DNS retries for Solaris and other systems
+ * whose gethostbyname_r version takes five arguments.
+ * - Move maximum number of DNS retries into a macro.
+ *
+ * Revision 1.41 2006/11/13 19:05:51 fabiankeil
+ * Make pthread mutex locking more generic. Instead of
+ * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
+ * and use mutex locking unless there is an _r function
+ * available. Better safe than sorry.
+ *
+ * Fixes "./configure --disable-pthread" and should result
+ * in less threading-related problems on pthread-using platforms,
+ * but it still doesn't fix BR#1122404.
+ *
+ * Revision 1.40 2006/09/02 15:36:42 fabiankeil
+ * Follow the OpenBSD port's lead and protect the resolve
+ * functions on OpenBSD as well.
+ *
+ * Revision 1.39 2006/08/03 02:46:41 david__schmidt
+ * Incorporate Fabian Keil's patch work:http://www.fabiankeil.de/sourcecode/privoxy/
+ *
+ * Revision 1.38 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.35.2.8 2006/01/21 16:16:08 david__schmidt
+ * Thanks to Edward Carrel for his patch to modernize OSX'spthreads support. See bug #1409623.
+ *
+ * Revision 1.35.2.7 2005/05/07 21:50:55 david__schmidt
+ * A few memory leaks plugged (mostly on error paths)
+ *
+ * Revision 1.35.2.6 2003/12/17 16:34:40 oes
+ * Cosmetics
+ *
+ * Revision 1.35.2.5 2003/04/29 11:32:54 oes
+ * Don't rely on h_addr being non-NULL after gethostbyname.
+ * Works around an oddness in Max OSX and closes bug #724796
+ *
+ * Revision 1.35.2.4 2003/04/04 12:40:20 oes
+ * Made sure the errno set by bind, not close[socket] is used in
+ * bind_port. Probably fixes bugs #713777, #705562.
+ *
+ * Revision 1.35.2.3 2003/03/07 03:41:04 david__schmidt
+ * Wrapping all *_r functions (the non-_r versions of them) with mutex semaphores for OSX. Hopefully this will take care of all of those pesky crash reports.
+ *
+ * Revision 1.35.2.2 2002/11/20 14:37:24 oes
+ * Fixed Win32 error logging in bind_port.
+ * Thanks to Oliver Stoeneberg for the hint.
+ *
+ * Revision 1.35.2.1 2002/05/26 23:41:27 joergs
+ * AmigaOS: Fixed wrong type of len in write_socket()
+ *
+ * Revision 1.35 2002/04/26 15:50:04 joergs
+ * AmigaOS: No socklen_t, added AMIGA to the systems using int instead.
+ *
+ * Revision 1.34 2002/04/08 20:31:41 swa
+ * fixed JB spelling
+ *
+ * Revision 1.33 2002/04/03 16:02:18 gliptak

+ * Killing warnings
+ *
+ * Revision 1.26 2002/03/11 22:07:02 david__schmidt
+ * OS/2 port maintenance:
+ * - Fixed EMX build - it had decayed a little
+ * - Fixed inexplicable crash during FD_ZERO - must be due to a bad macro.
+ * substituted a memset for now.
+ *
+ * Revision 1.25 2002/03/09 20:03:52 jongfoster
+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.24 2002/03/07 03:51:36 oes

+ * Enabling duplicate-socket detection for all platforms, not
+ * just Win32.
+ *
+ * Revision 1.19 2001/10/25 03:40:47 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.

+ * Killing warnings
+ *
+ * Revision 1.5 2002/03/09 20:03:52 jongfoster
+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.4 2002/03/07 03:51:36 oes
+ * - Improved handling of failed DNS lookups
+ * - Fixed compiler warnings etc
+ *
+ * Revision 1.3 2001/07/29 19:01:11 jongfoster

+ * - Silence LLVM/Clang complaint.
+ * - Make received_hup_signal static.
+ * - Hide definitions for basedir, pidfile and received_hup_signal
+ * from __EMX__ as they only seem to be used in case of #ifdef unix.
+ *
+ * Revision 1.183 2008/08/21 07:09:35 fabiankeil
+ * Accept Shoutcast responses again. Problem reported
+ * and fix suggested by Stefan in #2062860.
+ *
+ * Revision 1.182 2008/06/27 11:13:56 fabiankeil
+ * Fix possible NULL-pointer dereference reported

+ *
+ * Revision 1.181 2008/05/21 15:47:15 fabiankeil
+ * Streamline sed()'s prototype and declare
+ * the header parse and add structures static.
+ *
+ * Revision 1.180 2008/05/21 15:26:32 fabiankeil

+ *
+ * Revision 1.178 2008/05/10 13:23:38 fabiankeil
+ * Don't provide get_header() with the whole client state
+ * structure when it only needs access to csp->iob.
+ *
+ * Revision 1.177 2008/05/10 11:51:12 fabiankeil
+ * Make the "read the rest of the headers" loop a bit more readable.
+ *
+ * Revision 1.176 2008/05/10 11:37:57 fabiankeil
+ * - Instead of logging when the IIS5 hack is enabled, log when it fails.
+ * - Remove useless comment.
+ *
+ * Revision 1.175 2008/05/09 18:53:59 fabiankeil
+ * Fix comment grammar.
+ *
+ * Revision 1.174 2008/05/07 18:05:53 fabiankeil
+ * Remove the pointless buffer in client_protocol_is_unsupported().
+ *
+ * Revision 1.173 2008/05/06 15:09:00 fabiankeil
+ * Least-effort fix for bug #1821930 (reported by Lee):
+ * If the response doesn't look like HTTP,

+ *
+ * Revision 1.172 2008/04/16 16:38:21 fabiankeil
+ * Don't pass the whole csp structure to flush_socket()

+ *
+ * Revision 1.169 2008/03/04 18:30:39 fabiankeil
+ * Remove the treat-forbidden-connects-like-blocks action. We now
+ * use the "blocked" page for forbidden CONNECT requests by default.
+ *
+ * Revision 1.168 2008/03/02 12:25:25 fabiankeil
+ * Also use shiny new connect_port_is_forbidden() in jcc.c.
+ *
+ * Revision 1.167 2008/02/23 16:57:12 fabiankeil
+ * Rename url_actions() to get_url_actions() and let it

+ *
+ * Revision 1.166 2008/02/23 16:33:43 fabiankeil
+ * Let forward_url() use the standard parameter ordering

+ *
+ * Revision 1.165 2008/02/02 19:36:56 fabiankeil
+ * Remove the "Listening ... for local connections only" log message.
+ * Whether or not remote connections are able to reach Privoxy is up
+ * to the operating system.
+ *
+ * Revision 1.164 2007/12/16 18:32:46 fabiankeil
+ * Prevent the log messages for CONNECT requests to unacceptable
+ * ports from printing the limit-connect argument as [null] if

+ *
+ * Revision 1.163 2007/12/13 01:47:11 david__schmidt
+ * Make sure all console-mode apps get a usage() instance
+ *
+ * Revision 1.162 2007/12/06 17:54:57 fabiankeil
+ * Reword NO_SERVER_DATA_RESPONSE to make it harder

+ *
+ * Revision 1.161 2007/12/04 19:44:22 fabiankeil
+ * Unbreak trustfile which previously didn't work without

+ *
+ * Revision 1.160 2007/11/29 18:00:29 fabiankeil
+ * Plug memory leak. Spotted by Valgrind, triggered by

+ *
+ * Revision 1.159 2007/11/24 14:34:09 fabiankeil
+ * In the HTTP snipplets, refer to the client as client.

+ * Revision 1.157 2007/11/03 17:34:49 fabiankeil
+ * Log the "weak randomization factor" warning only
+ * once for mingw32 and provide some more details.
+ *
+ * Revision 1.156 2007/11/01 18:20:58 fabiankeil
+ * Initialize log module after initializing mutexes, future
+ * deadlocks in that code should now work cross-platform.
+ *
+ * Revision 1.155 2007/10/23 20:12:45 fabiankeil
+ * Fix first CSUCCEED line to end in \r\n as required by RFC1945.
+ * Reported by Bert van Leeuwen in BR#1818808.

+ * Revision 1.154 2007/10/19 17:00:08 fabiankeil
+ * Downgrade "Flushing header and buffers" message to LOG_LEVEL_INFO.
+ *
+ * Revision 1.153 2007/10/14 14:12:41 fabiankeil
+ * When in daemon mode, close stderr after the configuration file has been
+ * parsed the first time. If logfile isn't set, stop logging. Fixes BR#897436.
+ *
+ * Revision 1.152 2007/10/04 18:03:34 fabiankeil
+ * - Fix a crash when parsing invalid requests whose first header
+ * is rejected by get_header(). Regression (re?)introduced
+ * in r1.143 by yours truly.
+ * - Move ACTION_VANILLA_WAFER handling into parsers.c's
+ * client_cookie_adder() to make sure send-vanilla-wafer can be
+ * controlled through tags (and thus regression-tested).
+ *
+ * Revision 1.151 2007/09/29 10:21:16 fabiankeil
+ * - Move get_filter_function() from jcc.c to filters.c
+ * so the filter functions can be static.
+ * - Don't bother filtering body-less responses.
+ *
+ * Revision 1.150 2007/09/28 16:39:29 fabiankeil
+ * Execute content filters through execute_content_filter().
+ *
+ * Revision 1.149 2007/09/04 15:08:48 fabiankeil
+ * Initialize req to NULL to make sure it's defined if the
+ * first read_socket() call fails. Reported by icmp30.
+ *
+ * Revision 1.148 2007/08/26 16:47:13 fabiankeil
+ * Add Stephen Gildea's --pre-chroot-nslookup patch [#1276666],
+ * extensive comments moved to user manual.
+ *
+ * Revision 1.147 2007/08/25 14:42:40 fabiankeil
+ * Don't crash if a broken header filter wiped out the request line.
+ *
+ * Revision 1.146 2007/08/20 17:09:32 fabiankeil
+ * Fix byte_count calculation in case of flushes
+ * and don't parse the server headers a second time.
+ *
+ * Revision 1.145 2007/08/19 13:13:31 fabiankeil
+ * - If there's a connection problem after we already forwarded
+ * parts of the original content, just hang up. Fixes BR#1776724.
+ * - Fix warnings about unused code on mingw32.
+ * - In case of flushes, calculate the byte count
+ * less incorrectly (I think).
+ *
+ * Revision 1.144 2007/08/11 14:43:22 fabiankeil
+ * Add some more prototypes for static functions.
+ *
+ * Revision 1.143 2007/08/05 13:58:19 fabiankeil
+ * Comment out request_contains_null_bytes() until it's used again.
+ *
+ * Revision 1.142 2007/08/05 13:50:26 fabiankeil
+ * #1763173 from Stefan Huehner: s@const static@static const@
+ * and declare some more functions static.
+ *
+ * Revision 1.141 2007/08/04 09:56:23 fabiankeil
+ * - Log rejected CONNECT requests with LOG_LEVEL_INFO
+ * and explain why they were rejected in the first place.
+ * - Fix the LOG_LEVEL_CLF message for crunches of unallowed
+ * CONNECT requests. The request line was missing.
+ * - Add two more XXX reminders as we don't have enough already.
+ *
+ * Revision 1.140 2007/07/21 11:51:36 fabiankeil
+ * As Hal noticed, checking dispatch_cgi() as the last cruncher
+ * looks like a bug if CGI requests are blocked unintentionally,
+ * so don't do it unless the user enabled the new config option
+ * "allow-cgi-request-crunching".
+ *
+ * Revision 1.139 2007/07/14 07:46:41 fabiankeil
+ * - Allow to rewrite the request destination behind the client's back.
+ * - Turn the weird-looking unconditional for loop that
+ * reads the client request into a conditional while loop.
+ * Move the stuff that only runs once out of the loop.
+ * - Move parts of chat(), server_content_type() and the
+ * necessary stuff to fix BR#1750917 into get_filter_function().
+ *
+ * Revision 1.138 2007/06/03 18:45:18 fabiankeil
+ * Temporary workaround for BR#1730105.
+ *
+ * Revision 1.137 2007/06/01 18:16:36 fabiankeil
+ * Use the same mutex for gethostbyname() and gethostbyaddr() to prevent
+ * deadlocks and crashes on OpenBSD and possibly other OS with neither
+ * gethostbyname_r() nor gethostaddr_r(). Closes BR#1729174.
+ * Thanks to Ralf Horstmann for report and solution.
+ *
+ * Revision 1.136 2007/06/01 16:41:11 fabiankeil
+ * Add forward-override{} to change the forwarding settings through
+ * action sections. This is mainly interesting to forward different
+ * clients differently (for example based on User-Agent or request
+ * origin).
+ *
+ * Revision 1.135 2007/05/24 17:03:50 fabiankeil
+ * - Let usage() mention the --chroot parameter.
+ * - Use read_socket() consistently and always leave
+ * the last buffer byte alone, even in cases where
+ * null termination (currently) doesn't matter.
+ *
+ * Revision 1.134 2007/05/16 14:59:46 fabiankeil
+ * - Fix config file loading on Unix if no config file is specified.
+ * Since r1.97 Privoxy would always interpret the last argument as
+ * config file, even if it's a valid command line option.
+ * - Abort in case of unrecognized command line options. Closes #1719696.
+ * - Remove a bunch of unnecessary strcpy() calls (yay for c&p without thinking).
+ * - Replace the remaining strcpy() and strcat() calls with strlcpy() and strcat().
+ *
+ * Revision 1.133 2007/05/04 11:23:19 fabiankeil
+ * - Don't rerun crunchers that only depend on the request URL.
+ * - Don't count redirects and CGI requests as "blocked requests".
+ *
+ * Revision 1.132 2007/04/25 15:15:17 fabiankeil
+ * Support crunching based on tags created by server-header taggers.
+ *
+ * Revision 1.131 2007/04/22 13:24:50 fabiankeil
+ * Make HTTP snippets static (again). Add a Content-Type for those
+ * with content so the browser doesn't guess it based on the URL.
+ *
+ * Revision 1.130 2007/04/19 13:47:34 fabiankeil
+ * Move crunching and request line rebuilding out of chat().
+ *
+ * Revision 1.129 2007/04/15 16:39:20 fabiankeil
+ * Introduce tags as alternative way to specify which
+ * actions apply to a request. At the moment tags can be
+ * created based on client and server headers.
+ *
+ * Revision 1.128 2007/03/25 16:55:54 fabiankeil
+ * Don't CLF-log CONNECT requests twice.
+ *
+ * Revision 1.127 2007/03/20 13:53:17 fabiankeil
+ * Log the source address for ACL-related connection drops.
+ *
+ * Revision 1.126 2007/03/17 15:20:05 fabiankeil
+ * New config option: enforce-blocks.
+ *
+ * Revision 1.125 2007/03/09 14:12:00 fabiankeil
+ * - Move null byte check into separate function.
+ * - Don't confuse the client with error pages
+ * if a CONNECT request was already confirmed.
+ *
+ * Revision 1.124 2007/02/23 14:59:54 fabiankeil
+ * Speed up NULL byte escaping and only log the complete
+ * NULL byte requests with header debugging enabled.
+ *
+ * Revision 1.123 2007/02/21 18:42:10 fabiankeil
+ * Answer requests that contain NULL bytes with
+ * a custom response instead of waiting for more
+ * data until the client eventually hangs up.
+ *
+ * Revision 1.122 2007/02/07 11:12:02 fabiankeil
+ * - Move delivery and logging of crunched responses
+ * from chat() into send_crunch_response().
+ * - Display the reason for generating http_responses.
+ * - Log the content length for LOG_LEVEL_CLF correctly
+ * (still incorrect for some fixed responses).
+ * - Reword an incorrect comment about
+ * treat-forbidden-connects-like-blocks violating
+ * the specs.
+ * - Add some log messages.
+ *
+ * Revision 1.121 2007/01/27 10:52:56 fabiankeil
+ * Move mutex initialization into separate
+ * function and exit in case of errors.
+ *
+ * Revision 1.120 2007/01/26 14:18:42 fabiankeil
+ * - Start to reduce chat()'s line count and move
+ * parts of it into separate functions.
+ * - Add "HTTP/1.1 100 Continue" hack for BR 756734.
+ *
+ * Revision 1.119 2007/01/25 14:02:30 fabiankeil
+ * - Add Proxy-Agent header to HTTP snippets that are
+ * supposed to reach HTTP clients only.
+ * - Made a few CONNECT log messages more descriptive.
+ * - Catch completely empty server responses (as seen
+ * with Tor's fake ".noconnect" top level domain).
+ * - Use shiny new "forwarding-failed" template for socks errors.
+ *
+ * Revision 1.118 2007/01/07 07:43:43 joergs
+ * AmigaOS4 support added.
+ *
+ * Revision 1.117 2006/12/31 17:56:37 fabiankeil
+ * Added config option accept-intercepted-requests
+ * and disabled it by default.
+ *
+ * Revision 1.116 2006/12/29 19:08:22 fabiankeil
+ * Reverted parts of my last commit
+ * to keep error handling working.
+ *
+ * Revision 1.115 2006/12/29 17:38:57 fabiankeil
+ * Fixed gcc43 conversion warnings.
+ *
+ * Revision 1.114 2006/12/27 18:52:02 fabiankeil
+ * Fix -pedantic ISO C warning about converting
+ * from function pointer to object pointer.
+ *
+ * Revision 1.113 2006/12/26 17:38:50 fabiankeil
+ * Silence compiler warning I introduced with my last commit.
+ *
+ * Revision 1.112 2006/12/26 17:31:41 fabiankeil
+ * Mutex protect rand() if POSIX threading
+ * is used, warn the user if that's not possible
+ * and stop using it on _WIN32 where it could
+ * cause crashes.
+ *
+ * Revision 1.111 2006/12/23 16:15:06 fabiankeil
+ * Don't prevent core dumps by catching SIGABRT.
+ * It's rude and makes debugging unreasonable painful.
+ *
+ * Revision 1.110 2006/12/13 14:52:53 etresoft
+ * Fix build failure on MacOS X. Global symbols can be either static or extern, but not both.
+ *
+ * Revision 1.109 2006/12/06 19:41:40 fabiankeil
+ * Privoxy is now able to run as intercepting
+ * proxy in combination with any packet filter
+ * that does the port redirection. The destination
+ * is extracted from the "Host:" header which
+ * should be available for nearly all requests.
+ *
+ * Moved HTTP snipplets into jcc.c.
+ * Added error message for gopher proxy requests.
+ *
+ * Revision 1.108 2006/11/28 15:38:51 fabiankeil
+ * Only unlink the pidfile if it's actually used.
+ *
+ * Change order of interception checks to make
+ * it possible to block or redirect requests for
+ * the cgi pages.
+ *
+ * Revision 1.107 2006/11/13 19:05:51 fabiankeil
+ * Make pthread mutex locking more generic. Instead of
+ * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
+ * and use mutex locking unless there is an _r function
+ * available. Better safe than sorry.
+ *
+ * Fixes "./configure --disable-pthread" and should result
+ * in less threading-related problems on pthread-using platforms,
+ * but it still doesn't fix BR#1122404.
+ *
+ * Revision 1.106 2006/11/06 19:58:23 fabiankeil
+ * Move pthread.h inclusion from jcc.c to jcc.h.
+ * Fixes build on x86-freebsd1 (FreeBSD 5.4-RELEASE).
+ *
+ * Revision 1.105 2006/11/06 14:26:02 fabiankeil
+ * Don't exit after receiving the second SIGHUP on Solaris.
+ *
+ * Fixes BR 1052235, but the same problem may exist on other
+ * systems. Once 3.0.6 is out we should use sigset()
+ * where available and see if it breaks anything.
+ *
+ * Revision 1.104 2006/09/23 13:26:38 roro
+ * Replace TABs by spaces in source code.
+ *
+ * Revision 1.103 2006/09/21 12:54:43 fabiankeil
+ * Fix +redirect{}. Didn't work with -fast-redirects.
+ *
+ * Revision 1.102 2006/09/06 13:03:04 fabiankeil
+ * Respond with 400 and a short text message
+ * if the client tries to use Privoxy as FTP proxy.
+ *
+ * Revision 1.101 2006/09/06 09:23:37 fabiankeil
+ * Make number of retries in case of forwarded-connect problems
+ * a config file option (forwarded-connect-retries) and use 0 as
+ * default.
+ *
+ * Revision 1.100 2006/09/03 19:42:59 fabiankeil
+ * Set random(3) seed.
+ *
+ * Revision 1.99 2006/09/02 15:36:42 fabiankeil
+ * Follow the OpenBSD port's lead and protect the resolve
+ * functions on OpenBSD as well.
+ *
+ * Revision 1.98 2006/08/24 11:01:34 fabiankeil
+ * --user fix. Only use the user as group if no group is specified.
+ * Solves BR 1492612. Thanks to Spinor S. and David Laight.
+ *
+ * Revision 1.97 2006/08/18 15:23:17 david__schmidt
+ * Windows service (re-)integration
+ *
+ * The new args are:
+ *
+ * --install[:service_name]
+ * --uninstall[:service_name]
+ * --service
+ *
+ * They work as follows:
+ * --install will create a service for you and then terminate.
+ * By default the service name will be "privoxy" (without the quotes).
+ * However you can run multiple services if you wish, just by adding
+ * a colon and then a name (no spaces).
+ *
+ * --uninstall follows the exact same rules a --install.
+ *
+ * --service is used when the program is executed by the service
+ * control manager, and in normal circumstances would never be
+ * used as a command line argument.
+ *
+ * Revision 1.96 2006/08/15 20:12:36 david__schmidt
+ * Windows service integration
+ *

+ * Buffer Overrun in JPEG Processing (GDI+) Could
+ * Allow Code Execution (833987)
+ * Enabled with +inspect-jpegs in actions files.

+ * Wrapping all *_r functions (the non-_r versions of them) with
+ * mutex semaphores for OSX. Hopefully this will take care of all
+ * of those pesky crash reports.
+ *
+ * Revision 1.92.2.3 2003/02/28 12:53:06 oes
+ * Fixed two mostly harmless mem leaks
+ *
+ * Revision 1.92.2.2 2002/11/20 14:37:47 oes
+ * Fix: Head of global clients list now initialized to NULL
+ *
+ * Revision 1.92.2.1 2002/09/25 14:52:24 oes
+ * Added basic support for OPTIONS and TRACE HTTP methods:
+ * - New interceptor direct_response() added in chat().
+ * - sed() moved to earlier in the process, so that the
+ * Host: header is evaluated before actions and forwarding
+ * are decided on.
+ *
+ * Revision 1.92 2002/05/08 16:00:46 oes
+ * Chat's buffer handling:
+ * - Fixed bug with unchecked out-of-mem conditions
+ * while reading client request & server headers
+ * - No longer predict if the buffer limit will be exceeded
+ * in the next read -- check add_to_iob's new
+ * return code. If buffer couldn't be extended
+ * (policy or out-of-mem) while
+ * - reading from client: abort
+ * - reading server headers: send error page
+ * - buffering server body for filter: flush,
+ * and if that fails: send error page
+ *
+ * Revision 1.91 2002/04/08 20:35:58 swa
+ * fixed JB spelling
+ *
+ * Revision 1.90 2002/04/02 14:57:28 oes
+ * Made sending wafers independent of FEATURE_COOKIE_JAR
+ *
+ * Revision 1.89 2002/03/31 17:18:59 jongfoster
+ * Win32 only: Enabling STRICT to fix a VC++ compile warning.
+ *
+ * Revision 1.88 2002/03/27 14:32:43 david__schmidt
+ * More compiler warning message maintenance
+ *
+ * Revision 1.87 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * Revision 1.86 2002/03/25 17:04:55 david__schmidt
+ * Workaround for closing the jarfile before load_config() comes around again
+ *
+ * Revision 1.85 2002/03/24 15:23:33 jongfoster
+ * Name changes
+ *
+ * Revision 1.84 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.83 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.82 2002/03/13 00:27:05 jongfoster
+ * Killing warnings
+ *
+ * Revision 1.81 2002/03/12 01:42:50 oes
+ * Introduced modular filters
+ *
+ * Revision 1.80 2002/03/11 22:07:05 david__schmidt
+ * OS/2 port maintenance:
+ * - Fixed EMX build - it had decayed a little
+ * - Fixed inexplicable crash during FD_ZERO - must be due to a bad macro.
+ * substituted a memset for now.
+ *
+ * Revision 1.79 2002/03/09 20:03:52 jongfoster
+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.78 2002/03/08 21:35:04 oes
+ * Added optional group supplement to --user option. Will now use default group of user if no group given
+ *
+ * Revision 1.77 2002/03/07 03:52:06 oes
+ * - Fixed compiler warnings etc
+ * - Improved handling of failed DNS lookups
+ *
+ * Revision 1.76 2002/03/06 22:54:35 jongfoster
+ * Automated function-comment nitpicking.
+ *
+ * Revision 1.75 2002/03/06 10:02:19 oes
+ * Fixed stupid bug when --user was not given
+ *
+ * Revision 1.74 2002/03/06 00:49:31 jongfoster
+ * Fixing warning on Windows
+ * Making #ifdefs that refer to the same variable consistently
+ * use #ifdef unix rather than mixing #ifdef unix & #ifndef OS2
+ *
+ * Revision 1.73 2002/03/05 23:57:30 hal9
+ * Stray character 's' on line 1618 was breaking build.
+ *
+ * Revision 1.72 2002/03/05 21:33:45 david__schmidt
+ * - Re-enable OS/2 building after new parms were added
+ * - Fix false out of memory report when resolving CGI templates when no IP
+ * address is available of failed attempt (a la no such domain)
+ *
+ * Revision 1.71 2002/03/05 18:13:56 oes
+ * Added --user option

+ * Revision 1.69 2002/03/04 23:50:00 jongfoster
+ * Splitting off bind_port() call into bind_port_helper(), with
+ * improved logging.
+ *
+ * Revision 1.68 2002/03/04 20:17:32 oes
+ * Fixed usage info
+ *
+ * Revision 1.67 2002/03/04 18:18:57 oes
+ * - Removed _DEBUG mode
+ * - Cleand up cmdline parsing
+ * - Introduced --no-daemon, --pidfile options
+ * - Cleaned up signal handling:
+ * - Terminate cleanly on INT, TERM and ABRT
+ * - Schedule logfile for re-opening on HUP
+ * - Ignore CHLD and PIPE
+ * - Leave the rest with their default handlers
+ * - Uniform handler registration
+ * - Added usage() function
+ * - Played styleguide police
+ *
+ * Revision 1.66 2002/03/03 15:06:55 oes
+ * Re-enabled automatic config reloading
+ *
+ * Revision 1.65 2002/03/03 14:49:11 oes

+ *
+ * Revision 1.58 2001/11/30 23:37:24 jongfoster
+ * Renaming the Win32 config file to config.txt - this is almost the
+ * same as the corresponding UNIX name "config"
+ *
+ * Revision 1.57 2001/11/16 00:47:43 jongfoster

+ * Revision 1.52 2001/10/26 20:11:20 jongfoster
+ * Fixing type mismatch
+ *
+ * Revision 1.51 2001/10/26 17:38:28 oes
+ * Cosmetics
+ *
+ * Revision 1.50 2001/10/25 03:40:48 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.49 2001/10/23 21:41:35 jongfoster
+ * Added call to initialize the (statically-allocated of course)
+ * "out of memory" CGI response.
+ *
+ * Revision 1.48 2001/10/10 19:56:46 jongfoster
+ * Moving some code that wasn't cookie-related out of an #ifdef
+ * FEATURE_COOKIE_JAR
+ *
+ * Revision 1.47 2001/10/10 16:44:36 oes
+ * Added CONNECT destination port limitation check

+ * Revision 1.46 2001/10/08 15:17:41 oes
+ * Re-enabled SSL forwarding
+ *
+ * Revision 1.45 2001/10/07 15:42:11 oes
+ * Replaced 6 boolean members of csp with one bitmap (csp->flags)
+ *
+ * Moved downgrading of the HTTP version from parse_http_request to
+ * chat(), since we can't decide if it is necessary before we have
+ * determined the actions for the URL. The HTTP command is now
+ * *always* re-built so the repairs need no longer be special-cased.
+ *
+ * filter_popups now gets a csp pointer so it can raise the new
+ * CSP_FLAG_MODIFIED flag.
+ *
+ * Bugfix
+ *
+ * Added configurable size limit for the IOB. If the IOB grows so
+ * large that the next read would exceed the limit, the header
+ * is generated, and the header & unfiltered buffer are flushed
+ * to the client. Chat then continues in non-buffering,
+ * non-filtering body mode.

+ * Revision 1.44 2001/10/02 18:13:57 oes
+ * Ooops

+ * Revision 1.34 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.33 2001/07/29 19:32:00 jongfoster
+ * Renaming _main() [mingw32 only] to real_main(), for ANSI compliance.

+ * Applied pthread fix by Paul Lieverse
+ *
+ * Revision 1.30 2001/07/25 22:57:13 jongfoster
+ * __BEOS__ no longer overrides FEATURE_PTHREAD.
+ * This is because FEATURE_PTHREAD will soon be widely used, so I
+ * want to keep it simple.
+ *
+ * Revision 1.29 2001/07/24 12:47:06 oes
+ * Applied BeOS support update by Eugenia
+ *
+ * Revision 1.28 2001/07/23 13:26:12 oes
+ * Fixed bug in popup-killing for the first read that caused binary garbage to be sent between headers and body
+ *
+ * Revision 1.27 2001/07/19 19:09:47 haroon
+ * - Added code to take care of the situation where while processing the first
+ * server response (which includes the server header), after finding the end
+ * of the headers we were not looking past the end of the headers for
+ * content modification. I enabled it for filter_popups.
+ * Someone else should look to see if other similar operations should be
+ * done to the discarded portion of the buffer.
+ *
+ * Note 2001/07/20: No, the other content modification mechanisms will process
+ * the whole iob later anyway. --oes

+ * cosmetics
+ *
+ * Revision 1.25 2001/07/15 19:43:49 jongfoster
+ * Supports POSIX threads.
+ * Also removed some unused #includes.
+ *
+ * Revision 1.24 2001/07/13 14:00:40 oes
+ * - Generic content modification scheme:
+ * Each feature has its own applicability flag that is set
+ * from csp->action->flags.
+ * Replaced the "filtering" int flag , by a function pointer
+ * "content_filter" to the function that will do the content
+ * modification. If it is != NULL, the document will be buffered
+ * and processed through *content_filter, which must set
+ * csp->content_length and return a modified copy of the body
+ * or return NULL (on failiure).
+ * - Changed csp->is_text to the more generic bitmap csp->content_type
+ * which can currently take the valued CT_TEXT or CT_GIF
+ * - Reformatting etc
+ * - Removed all #ifdef PCRS
+ *
+ * Revision 1.23 2001/07/02 02:28:25 iwanttokeepanon
+ * Added "#ifdef ACL_FILES" conditional compilation to line 1291 to exclude
+ * the `block_acl' call. This prevents a compilation error when the user
+ * does not wish to use the "ACL" feature.
+ *
+ * Revision 1.22 2001/06/29 21:45:41 oes
+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.21 2001/06/29 13:29:36 oes
+ * - Cleaned up, improved comments
+ * - Unified all possible interceptors (CGI,
+ * block, trust, fast_redirect) in one
+ * place, with one (CGI) answer generation
+ * mechansim. Much clearer now.
+ * - Removed the GIF image generation, which
+ * is now done in filters.c:block_url()
+ * - Made error conditions like domain lookup
+ * failiure or (various) problems while talking
+ * to the server use cgi.c:error_response()
+ * instead of generating HTML/HTTP in chat() (yuck!)
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.20 2001/06/09 10:55:28 jongfoster
+ * Changing BUFSIZ ==> BUFFER_SIZE
+ *
+ * Revision 1.19 2001/06/07 23:12:52 jongfoster
+ * Replacing function pointer in struct gateway with a directly
+ * called function forwarded_connect().
+ * Replacing struct gateway with struct forward_spec
+ *
+ * Revision 1.18 2001/06/03 19:12:16 oes
+ * introduced new cgi handling
+ *
+ * Revision 1.17 2001/06/01 20:07:23 jongfoster
+ * Now uses action +image-blocker{} rather than config->tinygif
+ *
+ * Revision 1.16 2001/06/01 18:49:17 jongfoster
+ * Replaced "list_share" with "list" - the tiny memory gain was not
+ * worth the extra complexity.
+ *
+ * Revision 1.15 2001/05/31 21:24:47 jongfoster
+ * Changed "permission" to "action" throughout.
+ * Removed DEFAULT_USER_AGENT - it must now be specified manually.
+ * Moved vanilla wafer check into chat(), since we must now
+ * decide whether or not to add it based on the URL.
+ *
+ * Revision 1.14 2001/05/29 20:14:01 joergs
+ * AmigaOS bugfix: PCRS needs a lot of stack, stacksize for child threads
+ * increased.
+ *
+ * Revision 1.13 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.12 2001/05/27 22:17:04 oes
+ *
+ * - re_process_buffer no longer writes the modified buffer
+ * to the client, which was very ugly. It now returns the
+ * buffer, which it is then written by chat.
+ *
+ * - content_length now adjusts the Content-Length: header
+ * for modified documents rather than crunch()ing it.
+ * (Length info in csp->content_length, which is 0 for
+ * unmodified documents)
+ *
+ * - For this to work, sed() is called twice when filtering.
+ *
+ * Revision 1.11 2001/05/26 17:27:53 jongfoster
+ * Added support for CLF and fixed LOG_LEVEL_LOG.
+ * Also did CRLF->LF fix of my previous patch.
+ *
+ * Revision 1.10 2001/05/26 15:26:15 jongfoster
+ * ACL feature now provides more security by immediately dropping
+ * connections from untrusted hosts.
+ *
+ * Revision 1.9 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.8 2001/05/25 22:43:18 jongfoster
+ * Fixing minor memory leak and buffer overflow.
+ *
+ * Revision 1.7 2001/05/25 22:34:30 jongfoster
+ * Hard tabs->Spaces
+ *
+ * Revision 1.6 2001/05/23 00:13:58 joergs
+ * AmigaOS support fixed.
+ *
+ * Revision 1.5 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.4 2001/05/21 19:34:01 jongfoster
+ * Made failure to bind() a fatal error.
+ *
+ * Revision 1.3 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.2 2001/05/17 22:34:44 oes
+ * - Added hint on GIF char array generation to jcc.c
+ * - Cleaned CRLF's from the sources and related files
+ * - Repaired logging for REF and FRC
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:56 oes
+ * Initial import of version 2.9.3 source tree

+ * Revisions :
+ * $Log: jcc.h,v $
+ * Revision 1.25 2008/10/09 18:21:41 fabiankeil
+ * Flush work-in-progress changes to keep outgoing connections
+ * alive where possible. Incomplete and mostly #ifdef'd out.
+ *
+ * Revision 1.24 2008/09/07 12:35:05 fabiankeil
+ * Add mutex lock support for _WIN32.
+ *
+ * Revision 1.23 2008/09/04 08:13:58 fabiankeil
+ * Prepare for critical sections on Windows by adding a
+ * layer of indirection before the pthread mutex functions.
+ *
+ * Revision 1.22 2007/06/01 18:16:36 fabiankeil
+ * Use the same mutex for gethostbyname() and gethostbyaddr() to prevent
+ * deadlocks and crashes on OpenBSD and possibly other OS with neither
+ * gethostbyname_r() nor gethostaddr_r(). Closes BR#1729174.
+ * Thanks to Ralf Horstmann for report and solution.
+ *
+ * Revision 1.21 2007/04/22 13:18:06 fabiankeil
+ * Keep the HTTP snippets local.
+ *
+ * Revision 1.20 2006/12/26 17:31:41 fabiankeil
+ * Mutex protect rand() if POSIX threading
+ * is used, warn the user if that's not possible
+ * and stop using it on _WIN32 where it could
+ * cause crashes.
+ *
+ * Revision 1.19 2006/12/06 19:41:39 fabiankeil
+ * Privoxy is now able to run as intercepting
+ * proxy in combination with any packet filter
+ * that does the port redirection. The destination
+ * is extracted from the "Host:" header which
+ * should be available for nearly all requests.
+ *
+ * Moved HTTP snipplets into jcc.c.
+ * Added error message for gopher proxy requests.
+ *
+ * Revision 1.18 2006/11/13 19:05:51 fabiankeil
+ * Make pthread mutex locking more generic. Instead of
+ * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
+ * and use mutex locking unless there is an _r function
+ * available. Better safe than sorry.
+ *
+ * Fixes "./configure --disable-pthread" and should result
+ * in less threading-related problems on pthread-using platforms,
+ * but it still doesn't fix BR#1122404.
+ *
+ * Revision 1.17 2006/11/06 19:58:23 fabiankeil
+ * Move pthread.h inclusion from jcc.c to jcc.h.
+ * Fixes build on x86-freebsd1 (FreeBSD 5.4-RELEASE).
+ *
+ * Revision 1.16 2006/09/02 15:36:42 fabiankeil
+ * Follow the OpenBSD port's lead and protect the resolve
+ * functions on OpenBSD as well.
+ *
+ * Revision 1.15 2006/09/02 10:24:30 fabiankeil
+ * Include pthread.h for OpenBSD to make Privoxy build again.
+ *
+ * Tested shortly on OpenBSD 3.9 without problems, but the OpenBSD
+ * port has additional patches to use the mutexes OSX_DARWIN needs,
+ * and it should be investigated if they are still required for
+ * reliable operation.
+ *
+ * Revision 1.14 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.12.2.3 2006/01/21 16:16:08 david__schmidt
+ * Thanks to Edward Carrel for his patch to modernize OSX'spthreads support. See bug #1409623.
+ *
+ * Revision 1.12.2.2 2005/04/03 20:10:50 david__schmidt
+ * Thanks to Jindrich Makovicka for a race condition fix for the log
+ * file. The race condition remains for non-pthread implementations.
+ * Reference patch #1175720.
+ *
+ * Revision 1.12.2.1 2003/03/07 03:41:05 david__schmidt
+ * Wrapping all *_r functions (the non-_r versions of them) with mutex
+ * semaphores for OSX. Hopefully this will take care of all of those pesky
+ * crash reports.
+ *
+ * Revision 1.12 2002/03/26 22:29:55 swa
+ * we have a new homepage!
+ *
+ * Revision 1.11 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.10 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.9 2002/03/07 03:52:44 oes
+ * Set logging to tty for --no-daemon mode
+ *
+ * Revision 1.8 2002/03/04 18:19:49 oes
+ * Added extern const char *pidfile
+ *
+ * Revision 1.7 2001/11/05 21:41:43 steudten
+ * Add changes to be a real daemon just for unix os.
+ * (change cwd to /, detach from controlling tty, set
+ * process group and session leader to the own process.
+ * Add DBG() Macro.
+ * Add some fatal-error log message for failed malloc().
+ * Add '-d' if compiled with 'configure --with-debug' to
+ * enable debug output.
+ *
+ * Revision 1.6 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.5 2001/07/29 19:32:00 jongfoster
+ * Renaming _main() [mingw32 only] to real_main(), for ANSI compliance.
+ *
+ * Revision 1.4 2001/07/29 18:58:15 jongfoster
+ * Removing nested #includes, adding forward declarations for needed
+ * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
+ *
+ * Revision 1.3 2001/07/18 12:31:58 oes
+ * moved #define freez from jcc.h to project.h
+ *
+ * Revision 1.2 2001/05/31 21:24:47 jongfoster
+ * Changed "permission" to "action" throughout.
+ * Removed DEFAULT_USER_AGENT - it must now be specified manually.
+ * Moved vanilla wafer check into chat(), since we must now
+ * decide whether or not to add it based on the URL.
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:56 oes
+ * Initial import of version 2.9.3 source tree

+ * - Stop using strcpy().

+ *
+ * Revision 1.19 2007/04/17 18:14:06 fabiankeil
+ * Add list_contains_item().

+ * Revision 1.18 2006/12/28 19:21:23 fabiankeil

+ * Fixed compiler warnings
+ *
+ * Revision 1.12 2001/10/25 03:40:48 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.11 2001/10/23 21:21:03 jongfoster
+ * New error handling - error codes are now jb_errs, not ints.
+ * Changed the way map() handles out-of-memory, to dramatically
+ * reduce the amount of error-checking clutter needed.
+ *
+ * Revision 1.10 2001/09/16 17:30:24 jongfoster
+ * Fixing a compiler warning.
+ *
+ * Revision 1.9 2001/09/16 13:20:29 jongfoster
+ * Rewrite of list library. Now has seperate header and list_entry
+ * structures. Also added a large sprinking of assert()s to the list
+ * code.
+ *
+ * Revision 1.8 2001/08/07 14:00:20 oes
+ * Fixed comment
+ *
+ * Revision 1.7 2001/08/05 16:06:20 jongfoster
+ * Modifiying "struct map" so that there are now separate header and
+ * "map_entry" structures. This means that functions which modify a
+ * map no longer need to return a pointer to the modified map.
+ * Also, it no longer reverses the order of the entries (which may be
+ * important with some advanced template substitutions).
+ *
+ * Revision 1.6 2001/07/31 14:44:51 oes
+ * list_to_text() now appends empty line at end
+ *
+ * Revision 1.5 2001/06/29 21:45:41 oes
+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.4 2001/06/29 13:30:22 oes
+ * - Added Convenience function enlist_unique_header(),
+ * which takes the Header name and value as separate
+ * arguments and thus saves the pain of sprintf()ing
+ * and determining the Header name length to enlist_unique
+ * - Improved comments
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.3 2001/06/03 19:12:24 oes
+ * functions for new struct map, extended enlist_unique
+ *
+ * Revision 1.2 2001/06/01 18:49:17 jongfoster
+ * Replaced "list_share" with "list" - the tiny memory gain was not
+ * worth the extra complexity.
+ *
+ * Revision 1.1 2001/05/31 21:11:53 jongfoster
+ * - Moved linked list support to new "list.c" file.
+ * Structure definitions are still in project.h,
+ * function prototypes are now in "list.h".
+ * - Added support for "struct list_share", which is identical
+ * to "struct list" except it saves memory by not duplicating
+ * the strings. Obviously, this only works if there is some
+ * other way of managing the memory used by the strings.
+ * (These list_share lists are used for lists which last
+ * for only 1 request, and where all the list entries are
+ * just coming directly from entries in the actionsfile.)
+ * Note that you still need to destroy list_share lists
+ * properly to free the nodes - it's only the strings
+ * which are shared.

+ *
+ * Revision 1.12.2.1 2002/11/28 18:14:54 oes
+ * Added unmap function that removes all items with a given
+ * name from a map.
+ *
+ * Revision 1.12 2002/03/26 22:29:55 swa
+ * we have a new homepage!
+ *
+ * Revision 1.11 2002/03/24 13:25:43 swa

+ *
+ * Revision 1.10 2002/03/07 03:46:17 oes
+ * Fixed compiler warnings
+ *
+ * Revision 1.9 2001/10/23 21:21:03 jongfoster
+ * New error handling - error codes are now jb_errs, not ints.
+ * Changed the way map() handles out-of-memory, to dramatically
+ * reduce the amount of error-checking clutter needed.
+ *
+ * Revision 1.8 2001/09/16 17:30:24 jongfoster
+ * Fixing a compiler warning.
+ *
+ * Revision 1.7 2001/09/16 13:20:29 jongfoster
+ * Rewrite of list library. Now has seperate header and list_entry
+ * structures. Also added a large sprinking of assert()s to the list
+ * code.
+ *
+ * Revision 1.6 2001/08/05 16:06:20 jongfoster
+ * Modifiying "struct map" so that there are now separate header and
+ * "map_entry" structures. This means that functions which modify a
+ * map no longer need to return a pointer to the modified map.
+ * Also, it no longer reverses the order of the entries (which may be
+ * important with some advanced template substitutions).

+ * Revision 1.5 2001/07/29 18:43:08 jongfoster
+ * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
+ * ANSI C rules.

+ * - Introduced enlist_unique_header()
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.3 2001/06/03 11:03:48 oes
+ * introduced functions for new list type "map": map(), lookup(),
+ * free_map(), and extended enlist_unique
+ *
+ * Revision 1.2 2001/06/01 18:49:17 jongfoster
+ * Replaced "list_share" with "list" - the tiny memory gain was not
+ * worth the extra complexity.
+ *
+ * Revision 1.1 2001/05/31 21:11:53 jongfoster
+ * - Moved linked list support to new "list.c" file.
+ * Structure definitions are still in project.h,
+ * function prototypes are now in "list.h".
+ * - Added support for "struct list_share", which is identical
+ * to "struct list" except it saves memory by not duplicating
+ * the strings. Obviously, this only works if there is some
+ * other way of managing the memory used by the strings.
+ * (These list_share lists are used for lists which last
+ * for only 1 request, and where all the list entries are
+ * just coming directly from entries in the actionsfile.)
+ * Note that you still need to destroy list_share lists
+ * properly to free the nodes - it's only the strings
+ * which are shared.

+ * Revision 1.92 2009/03/18 20:43:19 fabiankeil
+ * Don't enable LOG_LEVEL_INFO by default and don't apply the user's

+ * Revision 1.91 2009/03/09 17:29:08 fabiankeil
+ * As of r1.88, the show-status page can use a single line for
+ * warnings about ignored directives and the names of the ignored

+ *
+ * Revision 1.90 2009/03/07 17:58:02 fabiankeil
+ * Fix two mingw32-only buffer overflows. Note that triggering
+ * them requires control over the configuration file in which
+ * case all bets are off anyway.
+ *
+ * Revision 1.89 2009/03/01 18:46:33 fabiankeil
+ * - Help clang understand that we aren't
+ * dereferencing NULL pointers here.
+ * - Some style fixes in the modified region.
+ *
+ * Revision 1.88 2009/02/28 10:57:10 fabiankeil

+ * Revision 1.86 2009/02/08 19:18:57 fabiankeil
+ * Now that we have the match-all.action file, the other action
+ * files changed their position in config->actions_file[] back
+ * to the way it was before standard.action got removed and the
+ * changes from revision 1.84 have to be reverted.
+ *
+ * Revision 1.85 2009/01/22 12:06:26 fabiankeil
+ * Don't keep connections alive when running single-threaded.

+ * Update mingw32 kludge accordingly.
+ *
+ * Revision 1.83 2008/12/20 14:53:55 fabiankeil

+ * Revision 1.80 2008/08/31 15:59:03 fabiankeil
+ * There's no reason to let remote toggling support depend

+ *
+ * Revision 1.79 2008/08/30 12:03:07 fabiankeil
+ * Remove FEATURE_COOKIE_JAR.
+ *
+ * Revision 1.78 2008/08/02 08:23:22 fabiankeil
+ * If the enforce-blocks directive is used with FEATURE_FORCE_LOAD
+ * disabled, log a message that blocks will always be enforced
+ * instead of complaining about an unrecognized directive.
+ * Reported by Pietro Leone.
+ *
+ * Revision 1.77 2008/05/26 16:13:22 fabiankeil

+ * Revision 1.65 2007/07/21 11:51:36 fabiankeil
+ * As Hal noticed, checking dispatch_cgi() as the last cruncher
+ * looks like a bug if CGI requests are blocked unintentionally,
+ * so don't do it unless the user enabled the new config option
+ * "allow-cgi-request-crunching".
+ *
+ * Revision 1.64 2007/05/21 10:44:08 fabiankeil
+ * - Use strlcpy() instead of strcpy().
+ * - Stop treating actions files special. Expect a complete file name
+ * (with or without path) like it's done for the rest of the files.
+ * Closes FR#588084.
+ * - Remove an unnecessary temporary memory allocation.
+ * - Don't log anything to the console when running as
+ * daemon and no errors occurred.

+ * Revision 1.63 2007/04/09 18:11:36 fabiankeil
+ * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
+ *
+ * Revision 1.62 2007/03/17 15:20:05 fabiankeil
+ * New config option: enforce-blocks.
+ *
+ * Revision 1.61 2007/03/16 16:47:35 fabiankeil

+ * Revision 1.53 2006/09/06 18:45:03 fabiankeil

+ *
+ * Formatting changed to Privoxy style, added call to
+ * cgi_error_no_template if the requested file doesn't
+ * exist and modified check whether or not Privoxy itself
+ * should serve the manual. Should work cross-platform now.
+ *
+ * Revision 1.52 2006/09/06 10:43:32 fabiankeil
+ * Added config option enable-remote-http-toggle
+ * to specify if Privoxy should recognize special

+ * behaviour. Disabled by default.
+ *
+ * Revision 1.51 2006/09/06 09:23:37 fabiankeil

+ * Revision 1.48.2.4 2003/04/11 12:06:14 oes
+ * Addressed bug #719435

+ * editing config.h) and then go to http://i.j.b/die, then the program

+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *

+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.6 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.5 2001/05/25 22:34:30 jongfoster
+ * Hard tabs->Spaces
+ *
+ * Revision 1.4 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.3 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.2 2001/05/17 23:01:01 oes
+ * - Cleaned CRLF's from the sources and related files
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:58 oes
+ * Initial import of version 2.9.3 source tree

+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.11.2.1 2003/03/11 11:53:59 oes
+ * Cosmetic: Renamed cryptic variable
+ *
+ * Revision 1.11 2002/03/26 22:29:55 swa
+ * we have a new homepage!
+ *
+ * Revision 1.10 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.9 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.8 2001/12/30 14:07:32 steudten
+ * - Add signal handling (unix)
+ * - Add SIGHUP handler (unix)
+ * - Add creation of pidfile (unix)
+ * - Add action 'top' in rc file (RH)
+ * - Add entry 'SIGNALS' to manpage
+ * - Add exit message to logfile (unix)
+ *
+ * Revision 1.7 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.6 2001/07/29 18:58:15 jongfoster
+ * Removing nested #includes, adding forward declarations for needed
+ * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
+ *
+ * Revision 1.5 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.4 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.3 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.2 2001/05/17 23:01:01 oes
+ * - Cleaned CRLF's from the sources and related files
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:58 oes
+ * Initial import of version 2.9.3 source tree

+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__

+ * Fixed line continuation problem
+ *
+ * Revision 1.13 2001/05/31 21:28:49 jongfoster
+ * Removed all permissionsfile code - it's now called the actions
+ * file, and (almost) all the code is in actions.c
+ *
+ * Revision 1.12 2001/05/31 17:32:31 oes
+ *
+ * - Enhanced domain part globbing with infix and prefix asterisk
+ * matching and optional unanchored operation
+ *
+ * Revision 1.11 2001/05/29 23:25:24 oes
+ *
+ * - load_config_line() and load_permissions_file() now use chomp()
+ *
+ * Revision 1.10 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.9 2001/05/26 17:12:07 jongfoster
+ * Fatal errors loading configuration files now give better error messages.
+ *
+ * Revision 1.8 2001/05/26 00:55:20 jongfoster
+ * Removing duplicated code. load_forwardfile() now uses create_url_spec()
+ *
+ * Revision 1.7 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.6 2001/05/23 12:27:33 oes
+ *
+ * Fixed ugly indentation of my last changes
+ *
+ * Revision 1.5 2001/05/23 10:39:05 oes
+ * - Added support for escaping the comment character
+ * in config files by a backslash
+ * - Added support for line continuation in config
+ * files
+ * - Fixed a buffer overflow bug with long config lines
+ *
+ * Revision 1.4 2001/05/22 18:56:28 oes
+ * CRLF -> LF
+ *
+ * Revision 1.3 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.2 2001/05/17 23:01:01 oes
+ * - Cleaned CRLF's from the sources and related files
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:59 oes
+ * Initial import of version 2.9.3 source tree

+ * Revisions :

+ * Revision 1.23 2008/03/30 14:52:10 fabiankeil
+ * Rename load_actions_file() and load_re_filterfile()
+ * as they load multiple files "now".
+ *
+ * Revision 1.22 2007/06/01 14:12:38 fabiankeil
+ * Add unload_forward_spec() in preparation for forward-override{}.
+ *
+ * Revision 1.21 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.19 2002/03/26 22:29:55 swa
+ * we have a new homepage!
+ *
+ * Revision 1.18 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.17 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.16 2002/03/07 03:46:17 oes
+ * Fixed compiler warnings
+ *
+ * Revision 1.15 2002/01/22 23:46:18 jongfoster
+ * Moving edit_read_line() and simple_read_line() to loaders.c, and
+ * extending them to support reading MS-DOS, Mac and UNIX style files
+ * on all platforms.
+ *
+ * Modifying read_config_line() (without changing it's prototype) to
+ * be a trivial wrapper for edit_read_line(). This means that we have
+ * one function to read a line and handle comments, which is common
+ * between the initialization code and the edit interface.
+ *
+ * Revision 1.14 2002/01/17 21:03:08 jongfoster
+ * Moving all our URL and URL pattern parsing code to urlmatch.c.
+ *
+ * Renaming free_url to free_url_spec, since it frees a struct url_spec.
+ *
+ * Revision 1.13 2001/12/30 14:07:32 steudten
+ * - Add signal handling (unix)
+ * - Add SIGHUP handler (unix)
+ * - Add creation of pidfile (unix)
+ * - Add action 'top' in rc file (RH)
+ * - Add entry 'SIGNALS' to manpage
+ * - Add exit message to logfile (unix)
+ *
+ * Revision 1.12 2001/11/07 00:02:13 steudten
+ * Add line number in error output for lineparsing for
+ * actionsfile and configfile.
+ * Special handling for CLF added.
+ *
+ * Revision 1.11 2001/10/23 21:38:53 jongfoster
+ * Adding error-checking to create_url_spec()
+ *
+ * Revision 1.10 2001/09/22 16:36:59 jongfoster
+ * Removing unused parameter fs from read_config_line()
+ *
+ * Revision 1.9 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.8 2001/07/29 18:58:15 jongfoster
+ * Removing nested #includes, adding forward declarations for needed
+ * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
+ *
+ * Revision 1.7 2001/07/13 14:01:54 oes
+ * Removed all #ifdef PCRS
+ *
+ * Revision 1.6 2001/06/07 23:14:38 jongfoster
+ * Removing ACL and forward file loaders - these files have
+ * been merged into the config file.
+ *
+ * Revision 1.5 2001/05/31 21:28:49 jongfoster
+ * Removed all permissionsfile code - it's now called the actions
+ * file, and (almost) all the code is in actions.c
+ *
+ * Revision 1.4 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.3 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.2 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.1.1.1 2001/05/15 13:59:00 oes
+ * Initial import of version 2.9.3 source tree

+ *
+ * Revision 1.45 2006/12/26 17:31:41 fabiankeil

+ * - Removed now-useless Privoxy 3.0.3 compatibility glue.
+ *
+ * - Moved randomization code into pick_from_range().

+ * because of the same reason.

+ * Added character class matching to trivimatch; renamed to simplematch
+ *
+ * Revision 1.4 2001/05/31 17:32:31 oes
+ *
+ * - Enhanced domain part globbing with infix and prefix asterisk

+ * Revision 1.2 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.1.1.1 2001/05/15 13:59:00 oes
+ * Initial import of version 2.9.3 source tree

+ * Description : Reallocate target_string and append text to it.
+ * This makes it easier to append to malloc'd strings.
+ * This is similar to the (removed) strsav(), but
+ * running out of memory isn't catastrophic.
+ *
+ * Programming style:
+ *
+ * The following style provides sufficient error
+ * checking for this routine, with minimal clutter
+ * in the source code. It is recommended if you
+ * have many calls to this function:
+ *
+ * char * s = strdup(...); // don't check for error
+ * string_append(&s, ...); // don't check for error
+ * string_append(&s, ...); // don't check for error
+ * string_append(&s, ...); // don't check for error
+ * if (NULL == s) { ... handle error ... }
+ *
+ * OR, equivalently:
+ *
+ * char * s = strdup(...); // don't check for error
+ * string_append(&s, ...); // don't check for error
+ * string_append(&s, ...); // don't check for error
+ * if (string_append(&s, ...)) {... handle error ...}
+ *
+ * Parameters :
+ * 1 : target_string = Pointer to old text that is to be
+ * extended. *target_string will be free()d by this
+ * routine. target_string must be non-NULL.
+ * If *target_string is NULL, this routine will
+ * do nothing and return with an error - this allows
+ * you to make many calls to this routine and only
+ * check for errors after the last one.
+ * 2 : text_to_append = Text to be appended to old.
+ * Must not be NULL.
+ *
+ * Returns : JB_ERR_OK on success, and sets *target_string
+ * to newly malloc'ed appended string. Caller
+ * must free(*target_string).
+ * JB_ERR_MEMORY on out-of-memory. (And free()s
+ * *target_string and sets it to NULL).

+ * For comparison, string_append requires that the

+ * Rationale: Too often, we want to do

+ snprintf.c
+ - a portable implementation of snprintf,
+ including vsnprintf.c, asnprintf, vasnprintf, asprintf, vasprintf
+
+ snprintf is a routine to convert numeric and string arguments to
+ formatted strings. It is similar to sprintf(3) provided in a system's
+ C library, yet it requires an additional argument - the buffer size -
+ and it guarantees never to store anything beyond the given buffer,
+ regardless of the format or arguments to be formatted. Some newer
+ operating systems do provide snprintf in their C library, but many do
+ not or do provide an inadequate (slow or idiosyncratic) version, which
+ calls for a portable implementation of this routine.

+ * Move simplematch() into urlmatch.c as it's only
+ * used to match (old-school) domain patterns.
+ *
+ * Revision 1.29 2007/09/09 18:20:20 fabiankeil
+ * Turn privoxy_strlcpy() into a function and try to work with
+ * b0rked snprintf() implementations too. Reported by icmp30.
+ *
+ * Revision 1.28 2007/05/11 11:48:16 fabiankeil
+ * - Delete strsav() which was replaced
+ * by string_append() years ago.
+ * - Add a strlcat() look-alike.
+ * - Use strlcat() and strlcpy() in those parts
+ * of the code that are run on unixes.
+ *
+ * Revision 1.27 2007/04/09 17:48:51 fabiankeil
+ * Check for HAVE_SNPRINTF instead of __OS2__
+ * before including the portable snprintf() code.
+ *
+ * Revision 1.26 2007/04/08 17:04:51 fabiankeil
+ * Add macro for strlcpy() in case the libc lacks it.
+ *
+ * Revision 1.25 2007/01/18 15:03:20 fabiankeil
+ * Don't include replacement timegm() if
+ * putenv() or tzset() isn't available.
+ *
+ * Revision 1.24 2006/08/17 17:15:10 fabiankeil
+ * - Back to timegm() using GnuPG's replacement if necessary.
+ * Using mktime() and localtime() could add a on hour offset if
+ * the randomize factor was big enough to lead to a summer/wintertime
+ * switch.
+ *
+ * - Removed now-useless Privoxy 3.0.3 compatibility glue.
+ *
+ * - Moved randomization code into pick_from_range().
+ *
+ * - Changed parse_header_time definition.
+ * time_t isn't guaranteed to be signed and
+ * if it isn't, -1 isn't available as error code.
+ * Changed some variable types in client_if_modified_since()
+ * because of the same reason.
+ *
+ * Revision 1.23 2006/07/18 14:48:47 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)

+ * is just copying a UNIX-specific fix to the Windows-specific part)
+ *
+ * Revision 1.11 2001/10/14 22:02:57 jongfoster
+ * New function string_append() which is like strsav(), but running
+ * out of memory isn't automatically FATAL.

+ *
+ * change long to int for prototype hash_string()
+ *

+ *
+ * - Introduced chomp()
+ * - Moved strsav() from showargs to miscutil
+ *
+ * Revision 1.2 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.1.1.1 2001/05/15 13:59:00 oes
+ * Initial import of version 2.9.3 source tree

+ * Change csp->expected_content and_csp->expected_content_length from
+ * size_t to unsigned long long to reduce the likelihood of integer
+ * overflows that would let us close the connection prematurely.
+ * Bug found while investigating #2669131, reported by cyberpatrol.
+ *
+ * Revision 1.152 2009/03/01 18:43:48 fabiankeil

+ * Fix some cparser warnings.
+ *
+ * Revision 1.149 2008/11/21 18:39:53 fabiankeil
+ * In case of CONNECT requests there's no point
+ * in trying to keep the connection alive.
+ *
+ * Revision 1.148 2008/11/16 12:43:49 fabiankeil
+ * Turn keep-alive support into a runtime feature
+ * that is disabled by setting keep-alive-timeout
+ * to a negative value.
+ *
+ * Revision 1.147 2008/11/04 17:20:31 fabiankeil
+ * HTTP/1.1 responses without Connection
+ * header imply keep-alive. Act accordingly.
+ *
+ * Revision 1.146 2008/10/12 16:46:35 fabiankeil
+ * Remove obsolete warning about delayed delivery with chunked
+ * transfer encoding and FEATURE_CONNECTION_KEEP_ALIVE enabled.
+ *
+ * Revision 1.145 2008/10/09 18:21:41 fabiankeil
+ * Flush work-in-progress changes to keep outgoing connections

+ * Treat unknown change-x-forwarded-for parameters as fatal errors.

+ * If change-x-forwarded-for{add} is used and the client

+ * lose all but the last one.
+ *
+ * Revision 1.142 2008/09/20 10:04:33 fabiankeil
+ * Remove hide-forwarded-for-headers action which has
+ * been obsoleted by change-x-forwarded-for{block}.
+ *
+ * Revision 1.141 2008/09/19 15:26:28 fabiankeil
+ * Add change-x-forwarded-for{} action to block or add
+ * X-Forwarded-For headers. Mostly based on code removed
+ * before 3.0.7.
+ *
+ * Revision 1.140 2008/09/12 17:51:43 fabiankeil

+ * s@Insufficent@Insufficient@
+ *
+ * Revision 1.135 2008/05/21 20:12:10 fabiankeil
+ * The whole point of strclean() is to modify the
+ * first parameter, so don't mark it immutable,
+ * even though the compiler lets us get away with it.
+ *
+ * Revision 1.134 2008/05/21 19:27:25 fabiankeil
+ * As the wafer actions are gone, we can stop including encode.h.

+ * Wrap memmove() calls in string_move()
+ * to document the purpose in one place.
+ *
+ * Revision 1.129 2008/05/17 14:02:07 fabiankeil
+ * Normalize linear header white space.
+ *
+ * Revision 1.128 2008/05/16 16:39:03 fabiankeil
+ * If a header is split across multiple lines,

+ *
+ * Revision 1.127 2008/05/10 13:23:38 fabiankeil
+ * Don't provide get_header() with the whole client state

+ *
+ * Revision 1.126 2008/05/03 16:40:45 fabiankeil
+ * Change content_filters_enabled()'s parameter from
+ * csp->action to action so it can be also used in the
+ * CGI code. Don't bother checking if there are filters
+ * loaded, as that's somewhat besides the point.
+ *
+ * Revision 1.125 2008/04/17 14:40:49 fabiankeil
+ * Provide get_http_time() with the buffer size so it doesn't
+ * have to blindly assume that the buffer is big enough.
+ *
+ * Revision 1.124 2008/04/16 16:38:21 fabiankeil
+ * Don't pass the whole csp structure to flush_socket()
+ * when it only needs a file descriptor and a buffer.
+ *
+ * Revision 1.123 2008/03/29 12:13:46 fabiankeil
+ * Remove send-wafer and send-vanilla-wafer actions.
+ *
+ * Revision 1.122 2008/03/28 15:13:39 fabiankeil
+ * Remove inspect-jpegs action.
+ *
+ * Revision 1.121 2008/01/05 21:37:03 fabiankeil

+ * which apparently are still supported by many servers.
+ *
+ * Revision 1.120 2008/01/04 17:43:45 fabiankeil
+ * Improve the warning messages that get logged if the action files
+ * "enable" filters but no filters of that type have been loaded.
+ *
+ * Revision 1.119 2007/12/28 18:32:51 fabiankeil
+ * In server_content_type():
+ * - Don't require leading white space when detecting image content types.
+ * - Change '... not replaced ...' message to sound less crazy if the text
+ * type actually is 'text/plain'.
+ * - Mark the 'text/plain == binary data' assumption for removal.
+ * - Remove a bunch of trailing white space.
+ *
+ * Revision 1.118 2007/12/28 16:56:35 fabiankeil
+ * Minor server_content_disposition() changes:
+ * - Don't regenerate the header name all lower-case.
+ * - Some white space fixes.
+ * - Remove useless log message in case of ENOMEM.
+ *
+ * Revision 1.117 2007/12/06 18:11:50 fabiankeil

+ * header as it seems to be mostly used by accident.

+ * Revision 1.116 2007/12/01 13:04:22 fabiankeil
+ * Fix a crash on mingw32 with some Last Modified times in the future.
+ *
+ * Revision 1.115 2007/11/02 16:52:50 fabiankeil
+ * Remove a "can't happen" error block which, over
+ * time, mutated into a "guaranteed to happen" block.
+ *
+ * Revision 1.114 2007/10/19 16:56:26 fabiankeil
+ * - Downgrade "Buffer limit reached" message to LOG_LEVEL_INFO.
+ * - Use shiny new content_filters_enabled() in client_range().
+ *
+ * Revision 1.113 2007/10/10 17:29:57 fabiankeil
+ * I forgot about Poland.
+ *
+ * Revision 1.112 2007/10/09 16:38:40 fabiankeil

+ * Move ACTION_VANILLA_WAFER handling from jcc's chat() into
+ * client_cookie_adder() to make sure send-vanilla-wafer can be
+ * controlled through tags (and thus regression-tested).
+ *
+ * Revision 1.110 2007/09/29 10:42:37 fabiankeil
+ * - Remove "scanning headers for" log message again.
+ * - Some more whitespace fixes.

+ *
+ * Revision 1.107 2007/08/28 18:16:32 fabiankeil
+ * Fix possible memory corruption in server_http, make sure it's not
+ * executed for ordinary server headers and mark some problems for later.
+ *

+ * Let content-type-overwrite{} honour force-text-mode again.

+ * Revision 1.99 2007/04/30 15:06:26 fabiankeil
+ * - Introduce dynamic pcrs jobs that can resolve variables.
+ * - Remove unnecessary update_action_bits_for_all_tags() call.
+ *
+ * Revision 1.98 2007/04/17 18:32:10 fabiankeil
+ * - Make tagging based on tags set by earlier taggers
+ * of the same kind possible.
+ * - Log whether or not new tags cause action bits updates
+ * (in which case a matching tag-pattern section exists).
+ * - Log if the user tries to set a tag that is already set.
+ *
+ * Revision 1.97 2007/04/15 16:39:21 fabiankeil
+ * Introduce tags as alternative way to specify which
+ * actions apply to a request. At the moment tags can be
+ * created based on client and server headers.
+ *
+ * Revision 1.96 2007/04/12 12:53:58 fabiankeil
+ * Log a warning if the content is compressed, filtering is
+ * enabled and Privoxy was compiled without zlib support.
+ * Closes FR#1673938.
+ *
+ * Revision 1.95 2007/03/25 14:26:40 fabiankeil
+ * - Fix warnings when compiled with glibc.
+ * - Don't use crumble() for cookie crunching.
+ * - Move cookie time parsing into parse_header_time().
+ * - Let parse_header_time() return a jb_err code
+ * instead of a pointer that can only be used to
+ * check for NULL anyway.
+ *
+ * Revision 1.94 2007/03/21 12:23:53 fabiankeil
+ * - Add better protection against malicious gzip headers.
+ * - Stop logging the first hundred bytes of decompressed content.
+ * It looks like it's working and there is always debug 16.
+ * - Log the content size after decompression in decompress_iob()
+ * instead of pcrs_filter_response().
+ *
+ * Revision 1.93 2007/03/20 15:21:44 fabiankeil
+ * - Use dedicated header filter actions instead of abusing "filter".
+ * Replace "filter-client-headers" and "filter-client-headers"
+ * with "server-header-filter" and "client-header-filter".
+ * - Remove filter_client_header() and filter_client_header(),
+ * filter_header() now checks the shiny new
+ * CSP_FLAG_CLIENT_HEADER_PARSING_DONE flag instead.
+ *
+ * Revision 1.92 2007/03/05 13:25:32 fabiankeil
+ * - Cosmetical changes for LOG_LEVEL_RE_FILTER messages.
+ * - Handle "Cookie:" and "Connection:" headers a bit smarter
+ * (don't crunch them just to recreate them later on).
+ * - Add another non-standard time format for the cookie
+ * expiration date detection.
+ * - Fix a valgrind warning.
+ *
+ * Revision 1.91 2007/02/24 12:27:32 fabiankeil
+ * Improve cookie expiration date detection.
+ *
+ * Revision 1.90 2007/02/08 19:12:35 fabiankeil
+ * Don't run server_content_length() the first time
+ * sed() parses server headers; only adjust the
+ * Content-Length header if the page was modified.
+ *
+ * Revision 1.89 2007/02/07 16:52:11 fabiankeil
+ * Fix log messages regarding the cookie time format
+ * (cookie and request URL were mixed up).
+ *
+ * Revision 1.88 2007/02/07 11:27:12 fabiankeil
+ * - Let decompress_iob()
+ * - not corrupt the content if decompression fails
+ * early. (the first byte(s) were lost).
+ * - use pointer arithmetics with defined outcome for
+ * a change.
+ * - Use a different kludge to remember a failed decompression.
+ *
+ * Revision 1.87 2007/01/31 16:21:38 fabiankeil
+ * Search for Max-Forwards headers case-insensitive,
+ * don't generate the "501 unsupported" message for invalid
+ * Max-Forwards values and don't increase negative ones.
+ *
+ * Revision 1.86 2007/01/30 13:05:26 fabiankeil
+ * - Let server_set_cookie() check the expiration date
+ * of cookies and don't touch the ones that are already
+ * expired. Fixes problems with low quality web applications
+ * as described in BR 932612.
+ *
+ * - Adjust comment in client_max_forwards to reality;
+ * remove invalid Max-Forwards headers.
+ *
+ * Revision 1.85 2007/01/26 15:33:46 fabiankeil
+ * Stop filter_header() from unintentionally removing
+ * empty header lines that were enlisted by the continue
+ * hack.
+ *
+ * Revision 1.84 2007/01/24 12:56:52 fabiankeil
+ * - Repeat the request URL before logging any headers.
+ * Makes reading the log easier in case of simultaneous requests.
+ * - If there are more than one Content-Type headers in one request,
+ * use the first one and remove the others.
+ * - Remove "newval" variable in server_content_type().
+ * It's only used once.
+ *
+ * Revision 1.83 2007/01/12 15:03:02 fabiankeil
+ * Correct a cast, check inflateEnd() exit code
+ * to see if we have to, replace sprintf calls
+ * with snprintf.
+ *
+ * Revision 1.82 2007/01/01 19:36:37 fabiankeil
+ * Integrate a modified version of Wil Mahan's
+ * zlib patch (PR #895531).
+ *
+ * Revision 1.81 2006/12/31 22:21:33 fabiankeil
+ * Skip empty filter files in filter_header()
+ * but don't ignore the ones that come afterwards.
+ * Fixes BR 1619208, this time for real.
+ *
+ * Revision 1.80 2006/12/29 19:08:22 fabiankeil
+ * Reverted parts of my last commit
+ * to keep error handling working.
+ *
+ * Revision 1.79 2006/12/29 18:04:40 fabiankeil
+ * Fixed gcc43 conversion warnings.
+ *
+ * Revision 1.78 2006/12/26 17:19:20 fabiankeil
+ * Bringing back the "useless" localtime() call
+ * I removed in revision 1.67. On some platforms
+ * it's necessary to prevent time zone offsets.
+ *
+ * Revision 1.77 2006/12/07 18:44:26 fabiankeil
+ * Rebuild request URL in get_destination_from_headers()
+ * to make sure redirect{pcrs command} works as expected
+ * for intercepted requests.
+ *
+ * Revision 1.76 2006/12/06 19:52:25 fabiankeil
+ * Added get_destination_from_headers().
+ *
+ * Revision 1.75 2006/11/13 19:05:51 fabiankeil
+ * Make pthread mutex locking more generic. Instead of
+ * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
+ * and use mutex locking unless there is an _r function
+ * available. Better safe than sorry.
+ *
+ * Fixes "./configure --disable-pthread" and should result
+ * in less threading-related problems on pthread-using platforms,
+ * but it still doesn't fix BR#1122404.
+ *
+ * Revision 1.74 2006/10/02 16:59:12 fabiankeil
+ * The special header "X-Filter: No" now disables
+ * header filtering as well.
+ *
+ * Revision 1.73 2006/09/23 13:26:38 roro
+ * Replace TABs by spaces in source code.
+ *
+ * Revision 1.72 2006/09/23 12:37:21 fabiankeil
+ * Don't print a log message every time filter_headers is
+ * entered or left. It only creates noise without any real
+ * information.
+ *
+ * Revision 1.71 2006/09/21 19:55:17 fabiankeil
+ * Fix +hide-if-modified-since{-n}.
+ *
+ * Revision 1.70 2006/09/08 12:06:34 fabiankeil
+ * Have hide-if-modified-since interpret the random
+ * range value as minutes instead of hours. Allows
+ * more fine-grained configuration.
+ *
+ * Revision 1.69 2006/09/06 16:25:51 fabiankeil
+ * Always have parse_header_time return a pointer
+ * that actual makes sense, even though we currently
+ * only need it to detect problems.
+ *
+ * Revision 1.68 2006/09/06 10:43:32 fabiankeil
+ * Added config option enable-remote-http-toggle
+ * to specify if Privoxy should recognize special
+ * headers (currently only X-Filter) to change its
+ * behaviour. Disabled by default.
+ *
+ * Revision 1.67 2006/09/04 11:01:26 fabiankeil
+ * After filtering de-chunked instances, remove
+ * "Transfer-Encoding" header entirely instead of changing
+ * it to "Transfer-Encoding: identity", which is invalid.
+ * Thanks Michael Shields <shields(a)msrl.com>. Fixes PR 1318658.
+ *
+ * Don't use localtime in parse_header_time. An empty time struct
+ * is good enough, it gets overwritten by strptime anyway.
+ *
+ * Revision 1.66 2006/09/03 19:38:28 fabiankeil
+ * Use gmtime_r if available, fallback to gmtime with mutex
+ * protection for MacOSX and use vanilla gmtime for the rest.
+ *
+ * Revision 1.65 2006/08/22 10:55:56 fabiankeil
+ * Changed client_referrer to use the right type (size_t) for
+ * hostlenght and to shorten the temporary referrer string with
+ * '\0' instead of adding a useless line break.
+ *
+ * Revision 1.64 2006/08/17 17:15:10 fabiankeil
+ * - Back to timegm() using GnuPG's replacement if necessary.
+ * Using mktime() and localtime() could add a on hour offset if
+ * the randomize factor was big enough to lead to a summer/wintertime
+ * switch.
+ *
+ * - Removed now-useless Privoxy 3.0.3 compatibility glue.
+ *
+ * - Moved randomization code into pick_from_range().
+ *
+ * - Changed parse_header_time definition.
+ * time_t isn't guaranteed to be signed and
+ * if it isn't, -1 isn't available as error code.
+ * Changed some variable types in client_if_modified_since()
+ * because of the same reason.
+ *
+ * Revision 1.63 2006/08/14 13:18:08 david__schmidt

+ * Split filter-headers{} into filter-client-headers{}
+ * and filter-server-headers{}.
+ * Added parse_header_time() to share some code.

+ * requests by one before forwarding
+ * - New parser function client_host which extracts the host

+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.

+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__

+ * Removed client_host, (was only required for the old 2.0.2-11 http://noijb.
+ * force-load), instead crumble Host: and add it (again) in client_host_adder
+ * (in case we get a HTTP/1.0 request without Host: header and forward it to

+ *
+ * Revision 1.32 2001/10/07 15:43:28 oes
+ * Removed FEATURE_DENY_GZIP and replaced it with client_accept_encoding,
+ * client_te and client_accept_encoding_adder, triggered by the new
+ * +no-compression action. For HTTP/1.1 the Accept-Encoding header is
+ * changed to allow only identity and chunked, and the TE header is
+ * crunched. For HTTP/1.0, Accept-Encoding is crunched.
+ *
+ * parse_http_request no longer does anything than parsing. The rewriting
+ * of http->cmd and version mangling are gone. It now also recognizes
+ * the put and delete methods and saves the url in http->url. Removed
+ * unused variable.
+ *
+ * renamed content_type and content_length to have the server_ prefix
+ *
+ * server_content_type now only works if csp->content_type != CT_TABOO
+ *
+ * added server_transfer_encoding, which
+ * - Sets CT_TABOO to prohibit filtering if encoding compresses
+ * - Raises the CSP_FLAG_CHUNKED flag if Encoding is "chunked"
+ * - Change from "chunked" to "identity" if body was chunked
+ * but has been de-chunked for filtering.
+ *
+ * added server_content_md5 which crunches any Content-MD5 headers
+ * if the body was modified.
+ *
+ * made server_http11 conditional on +downgrade action
+ *
+ * Replaced 6 boolean members of csp with one bitmap (csp->flags)

+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.9 2001/05/28 17:26:33 jongfoster
+ * Fixing segfault if last header was crunched.
+ * Fixing Windows build (snprintf() is _snprintf() under Win32, but we
+ * can use the cross-platform sprintf() instead.)
+ *
+ * Revision 1.8 2001/05/27 22:17:04 oes
+ *
+ * - re_process_buffer no longer writes the modified buffer
+ * to the client, which was very ugly. It now returns the
+ * buffer, which it is then written by chat.
+ *
+ * - content_length now adjusts the Content-Length: header
+ * for modified documents rather than crunch()ing it.
+ * (Length info in csp->content_length, which is 0 for
+ * unmodified documents)
+ *
+ * - For this to work, sed() is called twice when filtering.
+ *
+ * Revision 1.7 2001/05/27 13:19:06 oes
+ * Patched Joergs solution for the content-length in.
+ *
+ * Revision 1.6 2001/05/26 13:39:32 jongfoster
+ * Only crunches Content-Length header if applying RE filtering.
+ * Without this fix, Microsoft Windows Update wouldn't work.
+ *
+ * Revision 1.5 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.4 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.3 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.2 2001/05/17 23:02:36 oes
+ * - Made referrer option accept 'L' as a substitute for '§'
+ *
+ * Revision 1.1.1.1 2001/05/15 13:59:01 oes
+ * Initial import of version 2.9.3 source tree
+ *

+ * Revisions :
+ * $Log: parsers.h,v $
+ * Revision 1.49 2009/03/13 14:10:07 fabiankeil
+ * Fix some more harmless warnings on amd64.
+ *
+ * Revision 1.48 2008/05/30 15:57:23 fabiankeil
+ * Remove now-useless reference to debug.
+ *
+ * Revision 1.47 2008/05/21 20:12:11 fabiankeil
+ * The whole point of strclean() is to modify the
+ * first parameter, so don't mark it immutable,
+ * even though the compiler lets us get away with it.
+ *
+ * Revision 1.46 2008/05/21 15:47:14 fabiankeil
+ * Streamline sed()'s prototype and declare
+ * the header parse and add structures static.
+ *
+ * Revision 1.45 2008/05/20 20:13:30 fabiankeil
+ * Factor update_server_headers() out of sed(), ditch the
+ * first_run hack and make server_patterns_light static.
+ *
+ * Revision 1.44 2008/05/20 16:05:09 fabiankeil
+ * Move parsers structure definition from project.h to parsers.h.
+ *
+ * Revision 1.43 2008/05/10 13:23:38 fabiankeil
+ * Don't provide get_header() with the whole client state
+ * structure when it only needs access to csp->iob.
+ *
+ * Revision 1.42 2008/04/17 14:40:49 fabiankeil
+ * Provide get_http_time() with the buffer size so it doesn't
+ * have to blindly assume that the buffer is big enough.
+ *
+ * Revision 1.41 2008/04/16 16:38:21 fabiankeil
+ * Don't pass the whole csp structure to flush_socket()
+ * when it only needs a file descriptor and a buffer.
+ *
+ * Revision 1.40 2007/08/11 14:47:26 fabiankeil
+ * Remove the prototypes for functions that are only
+ * used in parsers.c and thus should be static.
+ *
+ * Revision 1.39 2007/06/01 16:31:55 fabiankeil
+ * Change sed() to return a jb_err in preparation for forward-override{}.
+ *
+ * Revision 1.38 2007/03/25 14:27:11 fabiankeil
+ * Let parse_header_time() return a jb_err code
+ * instead of a pointer that can only be used to
+ * check for NULL anyway.
+ *
+ * Revision 1.37 2007/03/20 15:22:17 fabiankeil
+ * - Remove filter_client_header() and filter_client_header(),
+ * filter_header() now checks the shiny new
+ * CSP_FLAG_CLIENT_HEADER_PARSING_DONE flag instead.
+ *
+ * Revision 1.36 2007/03/05 13:25:32 fabiankeil
+ * - Cosmetical changes for LOG_LEVEL_RE_FILTER messages.
+ * - Handle "Cookie:" and "Connection:" headers a bit smarter
+ * (don't crunch them just to recreate them later on).
+ * - Add another non-standard time format for the cookie
+ * expiration date detection.
+ * - Fix a valgrind warning.
+ *
+ * Revision 1.35 2007/01/01 19:36:37 fabiankeil
+ * Integrate a modified version of Wil Mahan's
+ * zlib patch (PR #895531).
+ *
+ * Revision 1.34 2006/12/29 19:08:22 fabiankeil
+ * Reverted parts of my last commit
+ * to keep error handling working.
+ *
+ * Revision 1.33 2006/12/29 18:04:40 fabiankeil
+ * Fixed gcc43 conversion warnings.
+ *
+ * Revision 1.32 2006/12/06 19:14:23 fabiankeil
+ * Added prototype for get_destination_from_headers().
+ *
+ * Revision 1.31 2006/08/17 17:15:10 fabiankeil
+ * - Back to timegm() using GnuPG's replacement if necessary.
+ * Using mktime() and localtime() could add a on hour offset if
+ * the randomize factor was big enough to lead to a summer/wintertime
+ * switch.
+ *
+ * - Removed now-useless Privoxy 3.0.3 compatibility glue.
+ *
+ * - Moved randomization code into pick_from_range().
+ *
+ * - Changed parse_header_time definition.
+ * time_t isn't guaranteed to be signed and
+ * if it isn't, -1 isn't available as error code.
+ * Changed some variable types in client_if_modified_since()
+ * because of the same reason.
+ *
+ * Revision 1.30 2006/08/14 08:25:19 fabiankeil
+ * Split filter-headers{} into filter-client-headers{}
+ * and filter-server-headers{}.
+ * Added parse_header_time() to share some code.
+ * Replaced timegm() with mktime().
+ *
+ * Revision 1.29 2006/08/03 02:46:41 david__schmidt
+ * Incorporate Fabian Keil's patch work:http://www.fabiankeil.de/sourcecode/privoxy/
+ *
+ * Revision 1.28 2006/07/18 14:48:47 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.26.2.1 2002/09/25 14:52:46 oes
+ * Added basic support for OPTIONS and TRACE HTTP methods:
+ * - New parser function client_max_forwards which decrements
+ * the Max-Forwards HTTP header field of OPTIONS and TRACE
+ * requests by one before forwarding
+ * - New parser function client_host which extracts the host
+ * and port information from the HTTP header field if the
+ * request URI was not absolute
+ * - Don't crumble and re-add the Host: header, but only generate
+ * and append if missing
+ *
+ * Revision 1.26 2002/05/08 15:59:53 oes
+ * Changed add_to_iob signature (now returns jb_err)
+ *
+ * Revision 1.25 2002/03/26 22:29:55 swa
+ * we have a new homepage!
+ *
+ * Revision 1.24 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.23 2002/03/13 00:27:05 jongfoster
+ * Killing warnings
+ *
+ * Revision 1.22 2002/03/09 20:03:52 jongfoster
+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.21 2002/03/07 03:46:17 oes
+ * Fixed compiler warnings
+ *
+ * Revision 1.20 2002/02/20 23:15:13 jongfoster
+ * Parsing functions now handle out-of-memory gracefully by returning
+ * an error code.
+ *
+ * Revision 1.19 2002/01/17 21:03:47 jongfoster
+ * Moving all our URL and URL pattern parsing code to urlmatch.c.
+ *
+ * Revision 1.18 2001/10/26 17:40:23 oes
+ * Introduced get_header_value()
+ * Removed client_accept()
+ *
+ * Revision 1.17 2001/10/13 12:47:32 joergs
+ * Removed client_host, added client_host_adder
+ *
+ * Revision 1.16 2001/10/07 18:50:16 oes
+ * Added server_content_encoding, renamed server_transfer_encoding
+ *
+ * Revision 1.15 2001/10/07 18:01:55 oes
+ * Changed server_http11 to server_http
+ *
+ * Revision 1.14 2001/10/07 15:45:48 oes
+ * added client_accept_encoding, client_te, client_accept_encoding_adder
+ *
+ * renamed content_type and content_length
+ *
+ * fixed client_host and strclean prototypes
+ *
+ * Revision 1.13 2001/09/29 12:56:03 joergs
+ * IJB now changes HTTP/1.1 to HTTP/1.0 in requests and answers.
+ *
+ * Revision 1.12 2001/09/13 23:05:50 jongfoster
+ * Changing the string paramater to the header parsers a "const".
+ *
+ * Revision 1.11 2001/07/31 14:46:53 oes
+ * Added prototype for connection_close_adder
+ *
+ * Revision 1.10 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx
+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.9 2001/07/29 18:43:08 jongfoster
+ * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
+ * ANSI C rules.
+ *
+ * Revision 1.8 2001/07/13 14:01:54 oes
+ * Removed all #ifdef PCRS
+ *
+ * Revision 1.7 2001/06/29 13:32:14 oes
+ * Removed logentry from cancelled commit
+ *
+ * Revision 1.6 2001/06/03 19:12:38 oes
+ * deleted const struct interceptors
+ *
+ * Revision 1.5 2001/05/31 21:30:33 jongfoster
+ * Removed list code - it's now in list.[ch]
+ * Renamed "permission" to "action", and changed many features
+ * to use the actions file rather than the global config.
+ *
+ * Revision 1.4 2001/05/27 13:19:06 oes
+ * Patched Joergs solution for the content-length in.
+ *
+ * Revision 1.3 2001/05/26 13:39:32 jongfoster
+ * Only crunches Content-Length header if applying RE filtering.
+ * Without this fix, Microsoft Windows Update wouldn't work.
+ *
+ * Revision 1.2 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.1.1.1 2001/05/15 13:59:01 oes
+ * Initial import of version 2.9.3 source tree

+# Homepage of this makefile - http://www.is.lg.ua/~paul/devel/
+# Homepage of original mingw32 project -
+# http://www.fu.is.saga-u.ac.jp/~colin/gcc.html
+#
+# How to use:
+# This makefile can:
+# 1. Create automatical .def file from list of objects
+# 2. Create .dll from objects and .def file, either automatical, or your
+# hand-written (maybe) file, which must have same basename as dll
+# WARNING! There MUST be object, which name match dll's name. Make sux.
+# 3. Create import library from .def (as for .dll, only its name required,
+# not dll itself)
+# By convention implibs for dll have .dll.a suffix, e.g. libstuff.dll.a
+# Why not just libstuff.a? 'Cos that's name for static lib, ok?
+# Process divided into 3 phases because:
+# 1. Pre-existent .def possible
+# 2. Generating implib is enough time-consuming
+#
+# Variables:
+# DLL_LDLIBS - libs for linking dll
+# DLL_LDFLAGS - flags for linking dll
+#
+# By using $(DLL_SUFFIX) instead of 'dll', e.g. stuff.$(DLL_SUFFIX)
+# you may help porting makefiles to other platforms
+#
+# Put this file in your make's include path (e.g. main include dir, for
+# more information see include section in make doc). Put in the beginning
+# of your own Makefile line "include dll.mk". Specify dependences, e.g.:
+#
+# Do all stuff in one step

+ChangeLog for PCRE
+------------------
+
+
+Version 3.4 22-Aug-00
+---------------------
+
+1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *.
+
+2. Diagnose condition (?(0) as an error instead of crashing on matching.
+
+
+Version 3.3 01-Aug-00
+---------------------
+
+1. If an octal character was given, but the value was greater than \377, it
+was not getting masked to the least significant bits, as documented. This could
+lead to crashes in some systems.
+
+2. Perl 5.6 (if not earlier versions) accepts classes like [a-\d] and treats
+the hyphen as a literal. PCRE used to give an error; it now behaves like Perl.
+
+3. Added the functions pcre_free_substring() and pcre_free_substring_list().
+These just pass their arguments on to (pcre_free)(), but they are provided
+because some uses of PCRE bind it to non-C systems that can call its functions,
+but cannot call free() or pcre_free() directly.
+
+4. Add "make test" as a synonym for "make check". Corrected some comments in
+the Makefile.
+
+5. Add $(DESTDIR)/ in front of all the paths in the "install" target in the
+Makefile.
+
+6. Changed the name of pgrep to pcregrep, because Solaris has introduced a
+command called pgrep for grepping around the active processes.
+
+7. Added the beginnings of support for UTF-8 character strings.
+
+8. Arranged for the Makefile to pass over the settings of CC, CFLAGS, and
+RANLIB to ./ltconfig so that they are used by libtool. I think these are all
+the relevant ones. (AR is not passed because ./ltconfig does its own figuring
+out for the ar command.)
+
+
+Version 3.2 12-May-00
+---------------------
+
+This is purely a bug fixing release.
+
+1. If the pattern /((Z)+|A)*/ was matched agained ZABCDEFG it matched Z instead
+of ZA. This was just one example of several cases that could provoke this bug,
+which was introduced by change 9 of version 2.00. The code for breaking
+infinite loops after an iteration that matches an empty string was't working
+correctly.
+
+2. The pcretest program was not imitating Perl correctly for the pattern /a*/g
+when matched against abbab (for example). After matching an empty string, it
+wasn't forcing anchoring when setting PCRE_NOTEMPTY for the next attempt; this
+caused it to match further down the string than it should.
+
+3. The code contained an inclusion of sys/types.h. It isn't clear why this
+was there because it doesn't seem to be needed, and it causes trouble on some
+systems, as it is not a Standard C header. It has been removed.
+
+4. Made 4 silly changes to the source to avoid stupid compiler warnings that
+were reported on the Macintosh. The changes were from
+
+ while ((c = *(++ptr)) != 0 && c != '\n');
+to
+ while ((c = *(++ptr)) != 0 && c != '\n') ;
+
+Totally extraordinary, but if that's what it takes...
+
+5. PCRE is being used in one environment where neither memmove() nor bcopy() is
+available. Added HAVE_BCOPY and an autoconf test for it; if neither
+HAVE_MEMMOVE nor HAVE_BCOPY is set, use a built-in emulation function which
+assumes the way PCRE uses memmove() (always moving upwards).
+
+6. PCRE is being used in one environment where strchr() is not available. There
+was only one use in pcre.c, and writing it out to avoid strchr() probably gives
+faster code anyway.
+
+
+Version 3.1 09-Feb-00
+---------------------
+
+The only change in this release is the fixing of some bugs in Makefile.in for
+the "install" target:
+
+(1) It was failing to install pcreposix.h.
+
+(2) It was overwriting the pcre.3 man page with the pcreposix.3 man page.
+
+
+Version 3.0 01-Feb-00
+---------------------
+
+1. Add support for the /+ modifier to perltest (to output $` like it does in
+pcretest).
+
+2. Add support for the /g modifier to perltest.
+
+3. Fix pcretest so that it behaves even more like Perl for /g when the pattern
+matches null strings.
+
+4. Fix perltest so that it doesn't do unwanted things when fed an empty
+pattern. Perl treats empty patterns specially - it reuses the most recent
+pattern, which is not what we want. Replace // by /(?#)/ in order to avoid this
+effect.
+
+5. The POSIX interface was broken in that it was just handing over the POSIX
+captured string vector to pcre_exec(), but (since release 2.00) PCRE has
+required a bigger vector, with some working space on the end. This means that
+the POSIX wrapper now has to get and free some memory, and copy the results.
+
+6. Added some simple autoconf support, placing the test data and the
+documentation in separate directories, re-organizing some of the
+information files, and making it build pcre-config (a GNU standard). Also added
+libtool support for building PCRE as a shared library, which is now the
+default.
+
+7. Got rid of the leading zero in the definition of PCRE_MINOR because 08 and
+09 are not valid octal constants. Single digits will be used for minor values
+less than 10.
+
+8. Defined REG_EXTENDED and REG_NOSUB as zero in the POSIX header, so that
+existing programs that set these in the POSIX interface can use PCRE without
+modification.
+
+9. Added a new function, pcre_fullinfo() with an extensible interface. It can
+return all that pcre_info() returns, plus additional data. The pcre_info()
+function is retained for compatibility, but is considered to be obsolete.
+
+10. Added experimental recursion feature (?R) to handle one common case that
+Perl 5.6 will be able to do with (?p{...}).
+
+11. Added support for POSIX character classes like [:alpha:], which Perl is
+adopting.
+
+
+Version 2.08 31-Aug-99
+----------------------
+
+1. When startoffset was not zero and the pattern began with ".*", PCRE was not
+trying to match at the startoffset position, but instead was moving forward to
+the next newline as if a previous match had failed.
+
+2. pcretest was not making use of PCRE_NOTEMPTY when repeating for /g and /G,
+and could get into a loop if a null string was matched other than at the start
+of the subject.
+
+3. Added definitions of PCRE_MAJOR and PCRE_MINOR to pcre.h so the version can
+be distinguished at compile time, and for completeness also added PCRE_DATE.
+
+5. Added Paul Sokolovsky's minor changes to make it easy to compile a Win32 DLL
+in GnuWin32 environments.
+
+
+Version 2.07 29-Jul-99
+----------------------
+
+1. The documentation is now supplied in plain text form and HTML as well as in
+the form of man page sources.
+
+2. C++ compilers don't like assigning (void *) values to other pointer types.
+In particular this affects malloc(). Although there is no problem in Standard
+C, I've put in casts to keep C++ compilers happy.
+
+3. Typo on pcretest.c; a cast of (unsigned char *) in the POSIX regexec() call
+should be (const char *).
+
+4. If NOPOSIX is defined, pcretest.c compiles without POSIX support. This may
+be useful for non-Unix systems who don't want to bother with the POSIX stuff.
+However, I haven't made this a standard facility. The documentation doesn't
+mention it, and the Makefile doesn't support it.
+
+5. The Makefile now contains an "install" target, with editable destinations at
+the top of the file. The pcretest program is not installed.
+
+6. pgrep -V now gives the PCRE version number and date.
+
+7. Fixed bug: a zero repetition after a literal string (e.g. /abcde{0}/) was
+causing the entire string to be ignored, instead of just the last character.
+
+8. If a pattern like /"([^\\"]+|\\.)*"/ is applied in the normal way to a
+non-matching string, it can take a very, very long time, even for strings of
+quite modest length, because of the nested recursion. PCRE now does better in
+some of these cases. It does this by remembering the last required literal
+character in the pattern, and pre-searching the subject to ensure it is present
+before running the real match. In other words, it applies a heuristic to detect
+some types of certain failure quickly, and in the above example, if presented
+with a string that has no trailing " it gives "no match" very quickly.
+
+9. A new runtime option PCRE_NOTEMPTY causes null string matches to be ignored;
+other alternatives are tried instead.
+
+
+Version 2.06 09-Jun-99
+----------------------
+
+1. Change pcretest's output for amount of store used to show just the code
+space, because the remainder (the data block) varies in size between 32-bit and
+64-bit systems.
+
+2. Added an extra argument to pcre_exec() to supply an offset in the subject to
+start matching at. This allows lookbehinds to work when searching for multiple
+occurrences in a string.
+
+3. Added additional options to pcretest for testing multiple occurrences:
+
+ /+ outputs the rest of the string that follows a match
+ /g loops for multiple occurrences, using the new startoffset argument
+ /G loops for multiple occurrences by passing an incremented pointer
+
+4. PCRE wasn't doing the "first character" optimization for patterns starting
+with \b or \B, though it was doing it for other lookbehind assertions. That is,
+it wasn't noticing that a match for a pattern such as /\bxyz/ has to start with
+the letter 'x'. On long subject strings, this gives a significant speed-up.
+
+
+Version 2.05 21-Apr-99
+----------------------
+
+1. Changed the type of magic_number from int to long int so that it works
+properly on 16-bit systems.
+
+2. Fixed a bug which caused patterns starting with .* not to work correctly
+when the subject string contained newline characters. PCRE was assuming
+anchoring for such patterns in all cases, which is not correct because .* will
+not pass a newline unless PCRE_DOTALL is set. It now assumes anchoring only if
+DOTALL is set at top level; otherwise it knows that patterns starting with .*
+must be retried after every newline in the subject.
+
+
+Version 2.04 18-Feb-99
+----------------------
+
+1. For parenthesized subpatterns with repeats whose minimum was zero, the
+computation of the store needed to hold the pattern was incorrect (too large).
+If such patterns were nested a few deep, this could multiply and become a real
+problem.
+
+2. Added /M option to pcretest to show the memory requirement of a specific
+pattern. Made -m a synonym of -s (which does this globally) for compatibility.
+
+3. Subpatterns of the form (regex){n,m} (i.e. limited maximum) were being
+compiled in such a way that the backtracking after subsequent failure was
+pessimal. Something like (a){0,3} was compiled as (a)?(a)?(a)? instead of
+((a)((a)(a)?)?)? with disastrous performance if the maximum was of any size.
+
+
+Version 2.03 02-Feb-99
+----------------------
+
+1. Fixed typo and small mistake in man page.
+
+2. Added 4th condition (GPL supersedes if conflict) and created separate
+LICENCE file containing the conditions.
+
+3. Updated pcretest so that patterns such as /abc\/def/ work like they do in
+Perl, that is the internal \ allows the delimiter to be included in the
+pattern. Locked out the use of \ as a delimiter. If \ immediately follows
+the final delimiter, add \ to the end of the pattern (to test the error).
+
+4. Added the convenience functions for extracting substrings after a successful
+match. Updated pcretest to make it able to test these functions.
+
+
+Version 2.02 14-Jan-99
+----------------------
+
+1. Initialized the working variables associated with each extraction so that
+their saving and restoring doesn't refer to uninitialized store.
+
+2. Put dummy code into study.c in order to trick the optimizer of the IBM C
+compiler for OS/2 into generating correct code. Apparently IBM isn't going to
+fix the problem.
+
+3. Pcretest: the timing code wasn't using LOOPREPEAT for timing execution
+calls, and wasn't printing the correct value for compiling calls. Increased the
+default value of LOOPREPEAT, and the number of significant figures in the
+times.
+
+4. Changed "/bin/rm" in the Makefile to "-rm" so it works on Windows NT.
+
+5. Renamed "deftables" as "dftables" to get it down to 8 characters, to avoid
+a building problem on Windows NT with a FAT file system.
+
+
+Version 2.01 21-Oct-98
+----------------------
+
+1. Changed the API for pcre_compile() to allow for the provision of a pointer
+to character tables built by pcre_maketables() in the current locale. If NULL
+is passed, the default tables are used.
+
+
+Version 2.00 24-Sep-98
+----------------------
+
+1. Since the (>?) facility is in Perl 5.005, don't require PCRE_EXTRA to enable
+it any more.
+
+2. Allow quantification of (?>) groups, and make it work correctly.
+
+3. The first character computation wasn't working for (?>) groups.
+
+4. Correct the implementation of \Z (it is permitted to match on the \n at the
+end of the subject) and add 5.005's \z, which really does match only at the
+very end of the subject.
+
+5. Remove the \X "cut" facility; Perl doesn't have it, and (?> is neater.
+
+6. Remove the ability to specify CASELESS, MULTILINE, DOTALL, and
+DOLLAR_END_ONLY at runtime, to make it possible to implement the Perl 5.005
+localized options. All options to pcre_study() were also removed.
+
+7. Add other new features from 5.005:
+
+ $(?<= positive lookbehind
+ $(?<! negative lookbehind
+ (?imsx-imsx) added the unsetting capability
+ such a setting is global if at outer level; local otherwise
+ (?imsx-imsx:) non-capturing groups with option setting
+ (?(cond)re|re) conditional pattern matching
+
+ A backreference to itself in a repeated group matches the previous
+ captured string.
+
+8. General tidying up of studying (both automatic and via "study")
+consequential on the addition of new assertions.
+
+9. As in 5.005, unlimited repeated groups that could match an empty substring
+are no longer faulted at compile time. Instead, the loop is forcibly broken at
+runtime if any iteration does actually match an empty substring.
+
+10. Include the RunTest script in the distribution.
+
+11. Added tests from the Perl 5.005_02 distribution. This showed up a few
+discrepancies, some of which were old and were also with respect to 5.004. They
+have now been fixed.
+
+
+Version 1.09 28-Apr-98
+----------------------
+
+1. A negated single character class followed by a quantifier with a minimum
+value of one (e.g. [^x]{1,6} ) was not compiled correctly. This could lead to
+program crashes, or just wrong answers. This did not apply to negated classes
+containing more than one character, or to minima other than one.
+
+
+Version 1.08 27-Mar-98
+----------------------
+
+1. Add PCRE_UNGREEDY to invert the greediness of quantifiers.
+
+2. Add (?U) and (?X) to set PCRE_UNGREEDY and PCRE_EXTRA respectively. The
+latter must appear before anything that relies on it in the pattern.
+
+
+Version 1.07 16-Feb-98
+----------------------
+
+1. A pattern such as /((a)*)*/ was not being diagnosed as in error (unlimited
+repeat of a potentially empty string).
+
+
+Version 1.06 23-Jan-98
+----------------------
+
+1. Added Markus Oberhumer's little patches for C++.
+
+2. Literal strings longer than 255 characters were broken.
+
+
+Version 1.05 23-Dec-97
+----------------------
+
+1. Negated character classes containing more than one character were failing if
+PCRE_CASELESS was set at run time.
+
+
+Version 1.04 19-Dec-97
+----------------------
+
+1. Corrected the man page, where some "const" qualifiers had been omitted.
+
+2. Made debugging output print "{0,xxx}" instead of just "{,xxx}" to agree with
+input syntax.
+
+3. Fixed memory leak which occurred when a regex with back references was
+matched with an offsets vector that wasn't big enough. The temporary memory
+that is used in this case wasn't being freed if the match failed.
+
+4. Tidied pcretest to ensure it frees memory that it gets.
+
+5. Temporary memory was being obtained in the case where the passed offsets
+vector was exactly big enough.
+
+6. Corrected definition of offsetof() from change 5 below.
+
+7. I had screwed up change 6 below and broken the rules for the use of
+setjmp(). Now fixed.
+
+
+Version 1.03 18-Dec-97
+----------------------
+
+1. A erroneous regex with a missing opening parenthesis was correctly
+diagnosed, but PCRE attempted to access brastack[-1], which could cause crashes
+on some systems.
+
+2. Replaced offsetof(real_pcre, code) by offsetof(real_pcre, code[0]) because
+it was reported that one broken compiler failed on the former because "code" is
+also an independent variable.
+
+3. The erroneous regex a[]b caused an array overrun reference.
+
+4. A regex ending with a one-character negative class (e.g. /[^k]$/) did not
+fail on data ending with that character. (It was going on too far, and checking
+the next character, typically a binary zero.) This was specific to the
+optimized code for single-character negative classes.
+
+5. Added a contributed patch from the TIN world which does the following:
+
+ + Add an undef for memmove, in case the the system defines a macro for it.
+
+ + Add a definition of offsetof(), in case there isn't one. (I don't know
+ the reason behind this - offsetof() is part of the ANSI standard - but
+ it does no harm).
+
+ + Reduce the ifdef's in pcre.c using macro DPRINTF, thereby eliminating
+ most of the places where whitespace preceded '#'. I have given up and
+ allowed the remaining 2 cases to be at the margin.
+
+ + Rename some variables in pcre to eliminate shadowing. This seems very
+ pedantic, but does no harm, of course.
+
+6. Moved the call to setjmp() into its own function, to get rid of warnings
+from gcc -Wall, and avoided calling it at all unless PCRE_EXTRA is used.
+
+7. Constructs such as \d{8,} were compiling into the equivalent of
+\d{8}\d{0,65527} instead of \d{8}\d* which didn't make much difference to the
+outcome, but in this particular case used more store than had been allocated,
+which caused the bug to be discovered because it threw up an internal error.
+
+8. The debugging code in both pcre and pcretest for outputting the compiled
+form of a regex was going wrong in the case of back references followed by
+curly-bracketed repeats.
+
+
+Version 1.02 12-Dec-97
+----------------------
+
+1. Typos in pcre.3 and comments in the source fixed.
+
+2. Applied a contributed patch to get rid of places where it used to remove
+'const' from variables, and fixed some signed/unsigned and uninitialized
+variable warnings.
+
+3. Added the "runtest" target to Makefile.
+
+4. Set default compiler flag to -O2 rather than just -O.
+
+
+Version 1.01 19-Nov-97
+----------------------
+
+1. PCRE was failing to diagnose unlimited repeat of empty string for patterns
+like /([ab]*)*/, that is, for classes with more than one character in them.
+
+2. Likewise, it wasn't diagnosing patterns with "once-only" subpatterns, such
+as /((?>a*))*/ (a PCRE_EXTRA facility).
+
+
+Version 1.00 18-Nov-97
+----------------------
+
+1. Added compile-time macros to support systems such as SunOS4 which don't have
+memmove() or strerror() but have other things that can be used instead.
+
+2. Arranged that "make clean" removes the executables.
+
+
+Version 0.99 27-Oct-97
+----------------------
+
+1. Fixed bug in code for optimizing classes with only one character. It was
+initializing a 32-byte map regardless, which could cause it to run off the end
+of the memory it had got.
+
+2. Added, conditional on PCRE_EXTRA, the proposed (?>REGEX) construction.
+
+
+Version 0.98 22-Oct-97
+----------------------
+
+1. Fixed bug in code for handling temporary memory usage when there are more
+back references than supplied space in the ovector. This could cause segfaults.
+
+
+Version 0.97 21-Oct-97
+----------------------
+
+1. Added the \X "cut" facility, conditional on PCRE_EXTRA.
+
+2. Optimized negated single characters not to use a bit map.
+
+3. Brought error texts together as macro definitions; clarified some of them;
+fixed one that was wrong - it said "range out of order" when it meant "invalid
+escape sequence".
+
+4. Changed some char * arguments to const char *.
+
+5. Added PCRE_NOTBOL and PCRE_NOTEOL (from POSIX).
+
+6. Added the POSIX-style API wrapper in pcreposix.a and testing facilities in
+pcretest.
+
+
+Version 0.96 16-Oct-97
+----------------------
+
+1. Added a simple "pgrep" utility to the distribution.
+
+2. Fixed an incompatibility with Perl: "{" is now treated as a normal character
+unless it appears in one of the precise forms "{ddd}", "{ddd,}", or "{ddd,ddd}"
+where "ddd" means "one or more decimal digits".
+
+3. Fixed serious bug. If a pattern had a back reference, but the call to
+pcre_exec() didn't supply a large enough ovector to record the related
+identifying subpattern, the match always failed. PCRE now remembers the number
+of the largest back reference, and gets some temporary memory in which to save
+the offsets during matching if necessary, in order to ensure that
+backreferences always work.
+
+4. Increased the compatibility with Perl in a number of ways:
+
+ (a) . no longer matches \n by default; an option PCRE_DOTALL is provided
+ to request this handling. The option can be set at compile or exec time.
+
+ (b) $ matches before a terminating newline by default; an option
+ PCRE_DOLLAR_ENDONLY is provided to override this (but not in multiline
+ mode). The option can be set at compile or exec time.
+
+ (c) The handling of \ followed by a digit other than 0 is now supposed to be
+ the same as Perl's. If the decimal number it represents is less than 10
+ or there aren't that many previous left capturing parentheses, an octal
+ escape is read. Inside a character class, it's always an octal escape,
+ even if it is a single digit.
+
+ (d) An escaped but undefined alphabetic character is taken as a literal,
+ unless PCRE_EXTRA is set. Currently this just reserves the remaining
+ escapes.
+
+ (e) {0} is now permitted. (The previous item is removed from the compiled
+ pattern).
+
+5. Changed all the names of code files so that the basic parts are no longer
+than 10 characters, and abolished the teeny "globals.c" file.
+
+6. Changed the handling of character classes; they are now done with a 32-byte
+bit map always.
+
+7. Added the -d and /D options to pcretest to make it possible to look at the
+internals of compilation without having to recompile pcre.
+
+
+Version 0.95 23-Sep-97
+----------------------
+
+1. Fixed bug in pre-pass concerning escaped "normal" characters such as \x5c or
+\x20 at the start of a run of normal characters. These were being treated as
+real characters, instead of the source characters being re-checked.
+
+
+Version 0.94 18-Sep-97
+----------------------
+
+1. The functions are now thread-safe, with the caveat that the global variables
+containing pointers to malloc() and free() or alternative functions are the
+same for all threads.
+
+2. Get pcre_study() to generate a bitmap of initial characters for non-
+anchored patterns when this is possible, and use it if passed to pcre_exec().
+
+
+Version 0.93 15-Sep-97
+----------------------
+
+1. /(b)|(:+)/ was computing an incorrect first character.
+
+2. Add pcre_study() to the API and the passing of pcre_extra to pcre_exec(),
+but not actually doing anything yet.
+
+3. Treat "-" characters in classes that cannot be part of ranges as literals,
+as Perl does (e.g. [-az] or [az-]).
+
+4. Set the anchored flag if a branch starts with .* or .*? because that tests
+all possible positions.
+
+5. Split up into different modules to avoid including unneeded functions in a
+compiled binary. However, compile and exec are still in one module. The "study"
+function is split off.
+
+6. The character tables are now in a separate module whose source is generated
+by an auxiliary program - but can then be edited by hand if required. There are
+now no calls to isalnum(), isspace(), isdigit(), isxdigit(), tolower() or
+toupper() in the code.
+
+7. Turn the malloc/free funtions variables into pcre_malloc and pcre_free and
+make them global. Abolish the function for setting them, as the caller can now
+set them directly.
+
+
+Version 0.92 11-Sep-97
+----------------------
+
+1. A repeat with a fixed maximum and a minimum of 1 for an ordinary character
+(e.g. /a{1,3}/) was broken (I mis-optimized it).
+
+2. Caseless matching was not working in character classes if the characters in
+the pattern were in upper case.
+
+3. Make ranges like [W-c] work in the same way as Perl for caseless matching.
+
+4. Make PCRE_ANCHORED public and accept as a compile option.
+
+5. Add an options word to pcre_exec() and accept PCRE_ANCHORED and
+PCRE_CASELESS at run time. Add escapes \A and \I to pcretest to cause it to
+pass them.
+
+6. Give an error if bad option bits passed at compile or run time.
+
+7. Add PCRE_MULTILINE at compile and exec time, and (?m) as well. Add \M to
+pcretest to cause it to pass that flag.
+
+8. Add pcre_info(), to get the number of identifying subpatterns, the stored
+options, and the first character, if set.
+
+9. Recognize C+ or C{n,m} where n >= 1 as providing a fixed starting character.
+
+
+Version 0.91 10-Sep-97
+----------------------
+
+1. PCRE was failing to diagnose unlimited repeats of subpatterns that could
+match the empty string as in /(a*)*/. It was looping and ultimately crashing.
+
+2. PCRE was looping on encountering an indefinitely repeated back reference to
+a subpattern that had matched an empty string, e.g. /(a|)\1*/. It now does what
+Perl does - treats the match as successful.

+Compiling PCRE on non-Unix systems
+----------------------------------
+
+If you want to compile PCRE for a non-Unix system, note that it consists
+entirely of code written in Standard C, and so should compile successfully
+on any machine with a Standard C compiler and library, using normal compiling
+commands to do the following:
+
+(1) Copy or rename the file config.in as config.h, and change the macros that
+define HAVE_STRERROR and HAVE_MEMMOVE to define them as 1 rather than 0.
+Unfortunately, because of the way Unix autoconf works, the default setting has
+to be 0.
+
+(2) Copy or rename the file pcre.in as pcre.h, and change the macro definitions
+for PCRE_MAJOR, PCRE_MINOR, and PCRE_DATE near its start to the values set in
+configure.in.
+
+(3) Compile dftables.c as a stand-alone program, and then run it with
+the standard output sent to chartables.c. This generates a set of standard
+character tables.
+
+(4) Compile maketables.c, get.c, study.c and pcre.c and link them all
+together into an object library in whichever form your system keeps such
+libraries. This is the pcre library (chartables.c gets included by means of an
+#include directive).
+
+(5) Similarly, compile pcreposix.c and link it as the pcreposix library.
+
+(6) Compile the test program pcretest.c. This needs the functions in the
+pcre and pcreposix libraries when linking.
+
+(7) Run pcretest on the testinput files in the testdata directory, and check
+that the output matches the corresponding testoutput files. You must use the
+-i option when checking testinput2.
+
+If you have a system without "configure" but where you can use a Makefile, edit
+Makefile.in to create Makefile, substituting suitable values for the variables
+at the head of the file.
+
+Some help in building a Win32 DLL of PCRE in GnuWin32 environments was

+Mingw32 (http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and
+CygWin (http://sourceware.cygnus.com/cygwin/) Paul comments:
+
+ For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get
+ pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically

+Technical Notes about PCRE
+--------------------------
+
+Many years ago I implemented some regular expression functions to an algorithm
+suggested by Martin Richards. These were not Unix-like in form, and were quite
+restricted in what they could do by comparison with Perl. The interesting part
+about the algorithm was that the amount of space required to hold the compiled
+form of an expression was known in advance. The code to apply an expression did
+not operate by backtracking, as the Henry Spencer and Perl code does, but
+instead checked all possibilities simultaneously by keeping a list of current
+states and checking all of them as it advanced through the subject string. (In
+the terminology of Jeffrey Friedl's book, it was a "DFA algorithm".) When the
+pattern was all used up, all remaining states were possible matches, and the
+one matching the longest subset of the subject string was chosen. This did not
+necessarily maximize the individual wild portions of the pattern, as is
+expected in Unix and Perl-style regular expressions.
+
+By contrast, the code originally written by Henry Spencer and subsequently
+heavily modified for Perl actually compiles the expression twice: once in a
+dummy mode in order to find out how much store will be needed, and then for
+real. The execution function operates by backtracking and maximizing (or,
+optionally, minimizing in Perl) the amount of the subject that matches
+individual wild portions of the pattern. This is an "NFA algorithm" in Friedl's
+terminology.
+
+For the set of functions that forms PCRE (which are unrelated to those
+mentioned above), I tried at first to invent an algorithm that used an amount
+of store bounded by a multiple of the number of characters in the pattern, to
+save on compiling time. However, because of the greater complexity in Perl
+regular expressions, I couldn't do this. In any case, a first pass through the
+pattern is needed, in order to find internal flag settings like (?i) at top
+level. So PCRE works by running a very degenerate first pass to calculate a
+maximum store size, and then a second pass to do the real compile - which may
+use a bit less than the predicted amount of store. The idea is that this is
+going to turn out faster because the first pass is degenerate and the second
+pass can just store stuff straight into the vector. It does make the compiling
+functions bigger, of course, but they have got quite big anyway to handle all
+the Perl stuff.
+
+The compiled form of a pattern is a vector of bytes, containing items of
+variable length. The first byte in an item is an opcode, and the length of the
+item is either implicit in the opcode or contained in the data bytes which
+follow it. A list of all the opcodes follows:
+
+Opcodes with no following data
+------------------------------
+
+These items are all just one byte long
+
+ OP_END end of pattern
+ OP_ANY match any character
+ OP_SOD match start of data: \A
+ OP_CIRC ^ (start of data, or after \n in multiline)
+ OP_NOT_WORD_BOUNDARY \W
+ OP_WORD_BOUNDARY \w
+ OP_NOT_DIGIT \D
+ OP_DIGIT \d
+ OP_NOT_WHITESPACE \S
+ OP_WHITESPACE \s
+ OP_NOT_WORDCHAR \W
+ OP_WORDCHAR \w
+ OP_EODN match end of data or \n at end: \Z
+ OP_EOD match end of data: \z
+ OP_DOLL $ (end of data, or before \n in multiline)
+ OP_RECURSE match the pattern recursively
+
+
+Repeating single characters
+---------------------------
+
+The common repeats (*, +, ?) when applied to a single character appear as
+two-byte items using the following opcodes:
+
+ OP_STAR
+ OP_MINSTAR
+ OP_PLUS
+ OP_MINPLUS
+ OP_QUERY
+ OP_MINQUERY
+
+Those with "MIN" in their name are the minimizing versions. Each is followed by
+the character that is to be repeated. Other repeats make use of
+
+ OP_UPTO
+ OP_MINUPTO
+ OP_EXACT
+
+which are followed by a two-byte count (most significant first) and the
+repeated character. OP_UPTO matches from 0 to the given number. A repeat with a
+non-zero minimum and a fixed maximum is coded as an OP_EXACT followed by an
+OP_UPTO (or OP_MINUPTO).
+
+
+Repeating character types
+-------------------------
+
+Repeats of things like \d are done exactly as for single characters, except
+that instead of a character, the opcode for the type is stored in the data
+byte. The opcodes are:
+
+ OP_TYPESTAR
+ OP_TYPEMINSTAR
+ OP_TYPEPLUS
+ OP_TYPEMINPLUS
+ OP_TYPEQUERY
+ OP_TYPEMINQUERY
+ OP_TYPEUPTO
+ OP_TYPEMINUPTO
+ OP_TYPEEXACT
+
+
+Matching a character string
+---------------------------
+
+The OP_CHARS opcode is followed by a one-byte count and then that number of
+characters. If there are more than 255 characters in sequence, successive
+instances of OP_CHARS are used.
+
+
+Character classes
+-----------------
+
+OP_CLASS is used for a character class, provided there are at least two
+characters in the class. If there is only one character, OP_CHARS is used for a
+positive class, and OP_NOT for a negative one (that is, for something like
+[^a]). Another set of repeating opcodes (OP_NOTSTAR etc.) are used for a
+repeated, negated, single-character class. The normal ones (OP_STAR etc.) are
+used for a repeated positive single-character class.
+
+OP_CLASS is followed by a 32-byte bit map containing a 1 bit for every
+character that is acceptable. The bits are counted from the least significant
+end of each byte.
+
+
+Back references
+---------------
+
+OP_REF is followed by a single byte containing the reference number.
+
+
+Repeating character classes and back references
+-----------------------------------------------
+
+Single-character classes are handled specially (see above). This applies to
+OP_CLASS and OP_REF. In both cases, the repeat information follows the base
+item. The matching code looks at the following opcode to see if it is one of
+
+ OP_CRSTAR
+ OP_CRMINSTAR
+ OP_CRPLUS
+ OP_CRMINPLUS
+ OP_CRQUERY
+ OP_CRMINQUERY
+ OP_CRRANGE
+ OP_CRMINRANGE
+
+All but the last two are just single-byte items. The others are followed by
+four bytes of data, comprising the minimum and maximum repeat counts.
+
+
+Brackets and alternation
+------------------------
+
+A pair of non-capturing (round) brackets is wrapped round each expression at
+compile time, so alternation always happens in the context of brackets.
+Non-capturing brackets use the opcode OP_BRA, while capturing brackets use
+OP_BRA+1, OP_BRA+2, etc. [Note for North Americans: "bracket" to some English
+speakers, including myself, can be round, square, curly, or pointy. Hence this
+usage.]
+
+A bracket opcode is followed by two bytes which give the offset to the next
+alternative OP_ALT or, if there aren't any branches, to the matching KET
+opcode. Each OP_ALT is followed by two bytes giving the offset to the next one,
+or to the KET opcode.
+
+OP_KET is used for subpatterns that do not repeat indefinitely, while
+OP_KETRMIN and OP_KETRMAX are used for indefinite repetitions, minimally or
+maximally respectively. All three are followed by two bytes giving (as a
+positive number) the offset back to the matching BRA opcode.
+
+If a subpattern is quantified such that it is permitted to match zero times, it
+is preceded by one of OP_BRAZERO or OP_BRAMINZERO. These are single-byte
+opcodes which tell the matcher that skipping this subpattern entirely is a
+valid branch.
+
+A subpattern with an indefinite maximum repetition is replicated in the
+compiled data its minimum number of times (or once with a BRAZERO if the
+minimum is zero), with the final copy terminating with a KETRMIN or KETRMAX as
+appropriate.
+
+A subpattern with a bounded maximum repetition is replicated in a nested
+fashion up to the maximum number of times, with BRAZERO or BRAMINZERO before
+each replication after the minimum, so that, for example, (abc){2,5} is
+compiled as (abc)(abc)((abc)((abc)(abc)?)?)?. The 200-bracket limit does not
+apply to these internally generated brackets.
+
+
+Assertions
+----------
+
+Forward assertions are just like other subpatterns, but starting with one of
+the opcodes OP_ASSERT or OP_ASSERT_NOT. Backward assertions use the opcodes
+OP_ASSERTBACK and OP_ASSERTBACK_NOT, and the first opcode inside the assertion
+is OP_REVERSE, followed by a two byte count of the number of characters to move
+back the pointer in the subject string. When operating in UTF-8 mode, the count
+is a character count rather than a byte count. A separate count is present in
+each alternative of a lookbehind assertion, allowing them to have different
+fixed lengths.
+
+
+Once-only subpatterns
+---------------------
+
+These are also just like other subpatterns, but they start with the opcode
+OP_ONCE.
+
+
+Conditional subpatterns
+-----------------------
+
+These are like other subpatterns, but they start with the opcode OP_COND. If
+the condition is a back reference, this is stored at the start of the
+subpattern using the opcode OP_CREF followed by one byte containing the
+reference number. Otherwise, a conditional subpattern will always start with
+one of the assertions.
+
+
+Changing options
+----------------
+
+If any of the /i, /m, or /s options are changed within a parenthesized group,
+an OP_OPT opcode is compiled, followed by one byte containing the new settings
+of these flags. If there are several alternatives in a group, there is an
+occurrence of OP_OPT at the start of all those following the first options
+change, to set appropriate options for the start of the alternative.
+Immediately after the end of the group there is another such item to reset the
+flags to their previous values. Other changes of flag within the pattern can be
+handled entirely at compile time, and so do not cause anything to be put into
+the compiled data.

+News about PCRE releases
+------------------------
+
+Release 3.3 01-Aug-00
+---------------------
+
+There is some support for UTF-8 character strings. This is incomplete and
+experimental. The documentation describes what is and what is not implemented.
+Otherwise, this is just a bug-fixing release.
+
+
+Release 3.0 01-Feb-00
+---------------------
+
+1. A "configure" script is now used to configure PCRE for Unix systems. It
+builds a Makefile, a config.h file, and the pcre-config script.
+
+2. PCRE is built as a shared library by default.
+
+3. There is support for POSIX classes such as [:alpha:].
+
+5. There is an experimental recursion feature.
+
+----------------------------------------------------------------------------
+ IMPORTANT FOR THOSE UPGRADING FROM VERSIONS BEFORE 2.00
+
+Please note that there has been a change in the API such that a larger
+ovector is required at matching time, to provide some additional workspace.
+The new man page has details. This change was necessary in order to support
+some of the new functionality in Perl 5.005.
+
+ IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.00
+
+Another (I hope this is the last!) change has been made to the API for the
+pcre_compile() function. An additional argument has been added to make it
+possible to pass over a pointer to character tables built in the current
+locale by pcre_maketables(). To use the default tables, this new arguement
+should be passed as NULL.
+
+ IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.05
+
+Yet another (and again I hope this really is the last) change has been made
+to the API for the pcre_exec() function. An additional argument has been
+added to make it possible to start the match other than at the start of the
+subject string. This is important if there are lookbehinds. The new man
+page has the details, but you just want to convert existing programs, all
+you need to do is to stick in a new fifth argument to pcre_exec(), with a
+value of zero. For example, change
+
+ pcre_exec(pattern, extra, subject, length, options, ovec, ovecsize)
+to
+ pcre_exec(pattern, extra, subject, length, 0, options, ovec, ovecsize)

+.SH DESCRIPTION
+The PCRE library is a set of functions that implement regular expression
+pattern matching using the same syntax and semantics as Perl 5, with just a few
+differences (see below). The current implementation corresponds to Perl 5.005,
+with some additional features from later versions. This includes some
+experimental, incomplete support for UTF-8 encoded strings. Details of exactly
+what is and what is not supported are given below.
+
+PCRE has its own native API, which is described in this document. There is also
+a set of wrapper functions that correspond to the POSIX regular expression API.
+These are described in the \fBpcreposix\fR documentation.
+
+The native API function prototypes are defined in the header file \fBpcre.h\fR,
+and on Unix systems the library itself is called \fBlibpcre.a\fR, so can be
+accessed by adding \fB-lpcre\fR to the command for linking an application which
+calls it. The header file defines the macros PCRE_MAJOR and PCRE_MINOR to
+contain the major and minor release numbers for the library. Applications can
+use these to include support for different releases.
+
+The functions \fBpcre_compile()\fR, \fBpcre_study()\fR, and \fBpcre_exec()\fR
+are used for compiling and matching regular expressions.
+
+The functions \fBpcre_copy_substring()\fR, \fBpcre_get_substring()\fR, and
+\fBpcre_get_substring_list()\fR are convenience functions for extracting
+captured substrings from a matched subject string; \fBpcre_free_substring()\fR
+and \fBpcre_free_substring_list()\fR are also provided, to free the memory used
+for extracted strings.
+
+The function \fBpcre_maketables()\fR is used (optionally) to build a set of
+character tables in the current locale for passing to \fBpcre_compile()\fR.
+
+The function \fBpcre_fullinfo()\fR is used to find out information about a
+compiled pattern; \fBpcre_info()\fR is an obsolete version which returns only
+some of the available information, but is retained for backwards compatibility.
+The function \fBpcre_version()\fR returns a pointer to a string containing the
+version of PCRE and its date of release.
+
+The global variables \fBpcre_malloc\fR and \fBpcre_free\fR initially contain
+the entry points of the standard \fBmalloc()\fR and \fBfree()\fR functions
+respectively. PCRE calls the memory management functions via these variables,
+so a calling program can replace them if it wishes to intercept the calls. This
+should be done before calling any PCRE functions.
+
+
+.SH MULTI-THREADING
+The PCRE functions can be used in multi-threading applications, with the
+proviso that the memory management functions pointed to by \fBpcre_malloc\fR
+and \fBpcre_free\fR are shared by all threads.
+
+The compiled form of a regular expression is not altered during matching, so
+the same compiled pattern can safely be used by several threads at once.
+
+
+.SH COMPILING A PATTERN
+The function \fBpcre_compile()\fR is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument \fIpattern\fR. A pointer to a single block of memory
+that is obtained via \fBpcre_malloc\fR is returned. This contains the
+compiled code and related data. The \fBpcre\fR type is defined for this for
+convenience, but in fact \fBpcre\fR is just a typedef for \fBvoid\fR, since the
+contents of the block are not externally defined. It is up to the caller to
+free the memory when it is no longer required.
+.PP
+The size of a compiled pattern is roughly proportional to the length of the
+pattern string, except that each character class (other than those containing
+just a single character, negated or not) requires 33 bytes, and repeat
+quantifiers with a minimum greater than one or a bounded maximum cause the
+relevant portions of the compiled pattern to be replicated.
+.PP
+The \fIoptions\fR argument contains independent bits that affect the
+compilation. It should be zero if no options are required. Some of the options,
+in particular, those that are compatible with Perl, can also be set and unset
+from within the pattern (see the detailed description of regular expressions
+below). For these options, the contents of the \fIoptions\fR argument specifies
+their initial settings at the start of compilation and execution. The
+PCRE_ANCHORED option can be set at the time of matching as well as at compile
+time.
+.PP
+If \fIerrptr\fR is NULL, \fBpcre_compile()\fR returns NULL immediately.
+Otherwise, if compilation of a pattern fails, \fBpcre_compile()\fR returns
+NULL, and sets the variable pointed to by \fIerrptr\fR to point to a textual
+error message. The offset from the start of the pattern to the character where
+the error was discovered is placed in the variable pointed to by
+\fIerroffset\fR, which must not be NULL. If it is, an immediate error is given.
+.PP
+If the final argument, \fItableptr\fR, is NULL, PCRE uses a default set of
+character tables which are built when it is compiled, using the default C
+locale. Otherwise, \fItableptr\fR must be the result of a call to
+\fBpcre_maketables()\fR. See the section on locale support below.
+.PP
+The following option bits are defined in the header file:
+
+ PCRE_ANCHORED
+
+If this bit is set, the pattern is forced to be "anchored", that is, it is
+constrained to match only at the start of the string which is being searched
+(the "subject string"). This effect can also be achieved by appropriate
+constructs in the pattern itself, which is the only way to do it in Perl.
+
+ PCRE_CASELESS
+
+If this bit is set, letters in the pattern match both upper and lower case
+letters. It is equivalent to Perl's /i option.
+
+ PCRE_DOLLAR_ENDONLY
+
+If this bit is set, a dollar metacharacter in the pattern matches only at the
+end of the subject string. Without this option, a dollar also matches
+immediately before the final character if it is a newline (but not before any
+other newlines). The PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is
+set. There is no equivalent to this option in Perl.
+
+ PCRE_DOTALL
+
+If this bit is set, a dot metacharater in the pattern matches all characters,
+including newlines. Without it, newlines are excluded. This option is
+equivalent to Perl's /s option. A negative class such as [^a] always matches a
+newline character, independent of the setting of this option.
+
+ PCRE_EXTENDED
+
+If this bit is set, whitespace data characters in the pattern are totally
+ignored except when escaped or inside a character class, and characters between
+an unescaped # outside a character class and the next newline character,
+inclusive, are also ignored. This is equivalent to Perl's /x option, and makes
+it possible to include comments inside complicated patterns. Note, however,
+that this applies only to data characters. Whitespace characters may never
+appear within special character sequences in a pattern, for example within the
+sequence (?( which introduces a conditional subpattern.
+
+ PCRE_EXTRA
+
+This option was invented in order to turn on additional functionality of PCRE
+that is incompatible with Perl, but it is currently of very little use. When
+set, any backslash in a pattern that is followed by a letter that has no
+special meaning causes an error, thus reserving these combinations for future
+expansion. By default, as in Perl, a backslash followed by a letter with no
+special meaning is treated as a literal. There are at present no other features
+controlled by this option. It can also be set by a (?X) option setting within a
+pattern.
+
+ PCRE_MULTILINE
+
+By default, PCRE treats the subject string as consisting of a single "line" of
+characters (even if it actually contains several newlines). The "start of line"
+metacharacter (^) matches only at the start of the string, while the "end of
+line" metacharacter ($) matches only at the end of the string, or before a
+terminating newline (unless PCRE_DOLLAR_ENDONLY is set). This is the same as
+Perl.
+
+When PCRE_MULTILINE it is set, the "start of line" and "end of line" constructs
+match immediately following or immediately before any newline in the subject
+string, respectively, as well as at the very start and end. This is equivalent
+to Perl's /m option. If there are no "\\n" characters in a subject string, or
+no occurrences of ^ or $ in a pattern, setting PCRE_MULTILINE has no
+effect.
+
+ PCRE_UNGREEDY
+
+This option inverts the "greediness" of the quantifiers so that they are not
+greedy by default, but become greedy if followed by "?". It is not compatible
+with Perl. It can also be set by a (?U) option setting within the pattern.
+
+ PCRE_UTF8
+
+This option causes PCRE to regard both the pattern and the subject as strings
+of UTF-8 characters instead of just byte strings. However, it is available only
+if PCRE has been built to include UTF-8 support. If not, the use of this option
+provokes an error. Support for UTF-8 is new, experimental, and incomplete.
+Details of exactly what it entails are given below.
+
+
+.SH STUDYING A PATTERN
+When a pattern is going to be used several times, it is worth spending more
+time analyzing it in order to speed up the time taken for matching. The
+function \fBpcre_study()\fR takes a pointer to a compiled pattern as its first
+argument, and returns a pointer to a \fBpcre_extra\fR block (another \fBvoid\fR
+typedef) containing additional information about the pattern; this can be
+passed to \fBpcre_exec()\fR. If no additional information is available, NULL
+is returned.
+
+The second argument contains option bits. At present, no options are defined
+for \fBpcre_study()\fR, and this argument should always be zero.
+
+The third argument for \fBpcre_study()\fR is a pointer to an error message. If
+studying succeeds (even if no data is returned), the variable it points to is
+set to NULL. Otherwise it points to a textual error message.
+
+At present, studying a pattern is useful only for non-anchored patterns that do
+not have a single fixed starting character. A bitmap of possible starting
+characters is created.
+
+
+.SH LOCALE SUPPORT
+PCRE handles caseless matching, and determines whether characters are letters,
+digits, or whatever, by reference to a set of tables. The library contains a
+default set of tables which is created in the default C locale when PCRE is
+compiled. This is used when the final argument of \fBpcre_compile()\fR is NULL,
+and is sufficient for many applications.
+
+An alternative set of tables can, however, be supplied. Such tables are built
+by calling the \fBpcre_maketables()\fR function, which has no arguments, in the
+relevant locale. The result can then be passed to \fBpcre_compile()\fR as often
+as necessary. For example, to build and use tables that are appropriate for the
+French locale (where accented characters with codes greater than 128 are
+treated as letters), the following code could be used:
+
+ setlocale(LC_CTYPE, "fr");
+ tables = pcre_maketables();
+ re = pcre_compile(..., tables);
+
+The tables are built in memory that is obtained via \fBpcre_malloc\fR. The
+pointer that is passed to \fBpcre_compile\fR is saved with the compiled
+pattern, and the same tables are used via this pointer by \fBpcre_study()\fR
+and \fBpcre_exec()\fR. Thus for any single pattern, compilation, studying and
+matching all happen in the same locale, but different patterns can be compiled
+in different locales. It is the caller's responsibility to ensure that the
+memory containing the tables remains available for as long as it is needed.
+
+
+.SH INFORMATION ABOUT A PATTERN
+The \fBpcre_fullinfo()\fR function returns information about a compiled
+pattern. It replaces the obsolete \fBpcre_info()\fR function, which is
+nevertheless retained for backwards compability (and is documented below).
+
+The first argument for \fBpcre_fullinfo()\fR is a pointer to the compiled
+pattern. The second argument is the result of \fBpcre_study()\fR, or NULL if
+the pattern was not studied. The third argument specifies which piece of
+information is required, while the fourth argument is a pointer to a variable
+to receive the data. The yield of the function is zero for success, or one of
+the following negative numbers:
+
+ PCRE_ERROR_NULL the argument \fIcode\fR was NULL
+ the argument \fIwhere\fR was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+ PCRE_ERROR_BADOPTION the value of \fIwhat\fR was invalid
+
+The possible values for the third argument are defined in \fBpcre.h\fR, and are
+as follows:
+
+ PCRE_INFO_OPTIONS
+
+Return a copy of the options with which the pattern was compiled. The fourth
+argument should point to au \fBunsigned long int\fR variable. These option bits
+are those specified in the call to \fBpcre_compile()\fR, modified by any
+top-level option settings within the pattern itself, and with the PCRE_ANCHORED
+bit forcibly set if the form of the pattern implies that it can match only at
+the start of a subject string.
+
+ PCRE_INFO_SIZE
+
+Return the size of the compiled pattern, that is, the value that was passed as
+the argument to \fBpcre_malloc()\fR when PCRE was getting memory in which to
+place the compiled data. The fourth argument should point to a \fBsize_t\fR
+variable.
+
+ PCRE_INFO_CAPTURECOUNT
+
+Return the number of capturing subpatterns in the pattern. The fourth argument
+should point to an \fbint\fR variable.
+
+ PCRE_INFO_BACKREFMAX
+
+Return the number of the highest back reference in the pattern. The fourth
+argument should point to an \fBint\fR variable. Zero is returned if there are
+no back references.
+
+ PCRE_INFO_FIRSTCHAR
+
+Return information about the first character of any matched string, for a
+non-anchored pattern. If there is a fixed first character, e.g. from a pattern
+such as (cat|cow|coyote), it is returned in the integer pointed to by
+\fIwhere\fR. Otherwise, if either
+
+(a) the pattern was compiled with the PCRE_MULTILINE option, and every branch
+starts with "^", or
+
+(b) every branch of the pattern starts with ".*" and PCRE_DOTALL is not set
+(if it were set, the pattern would be anchored),
+
+-1 is returned, indicating that the pattern matches only at the start of a
+subject string or after any "\\n" within the string. Otherwise -2 is returned.
+For anchored patterns, -2 is returned.
+
+ PCRE_INFO_FIRSTTABLE
+
+If the pattern was studied, and this resulted in the construction of a 256-bit
+table indicating a fixed set of characters for the first character in any
+matching string, a pointer to the table is returned. Otherwise NULL is
+returned. The fourth argument should point to an \fBunsigned char *\fR
+variable.
+
+ PCRE_INFO_LASTLITERAL
+
+For a non-anchored pattern, return the value of the rightmost literal character
+which must exist in any matched string, other than at its start. The fourth
+argument should point to an \fBint\fR variable. If there is no such character,
+or if the pattern is anchored, -1 is returned. For example, for the pattern
+/a\\d+z\\d+/ the returned value is 'z'.
+
+The \fBpcre_info()\fR function is now obsolete because its interface is too
+restrictive to return all the available data about a compiled pattern. New
+programs should use \fBpcre_fullinfo()\fR instead. The yield of
+\fBpcre_info()\fR is the number of capturing subpatterns, or one of the
+following negative numbers:
+
+ PCRE_ERROR_NULL the argument \fIcode\fR was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+
+If the \fIoptptr\fR argument is not NULL, a copy of the options with which the
+pattern was compiled is placed in the integer it points to (see
+PCRE_INFO_OPTIONS above).
+
+If the pattern is not anchored and the \fIfirstcharptr\fR argument is not NULL,
+it is used to pass back information about the first character of any matched
+string (see PCRE_INFO_FIRSTCHAR above).
+
+
+.SH MATCHING A PATTERN
+The function \fBpcre_exec()\fR is called to match a subject string against a
+pre-compiled pattern, which is passed in the \fIcode\fR argument. If the
+pattern has been studied, the result of the study should be passed in the
+\fIextra\fR argument. Otherwise this must be NULL.
+
+The PCRE_ANCHORED option can be passed in the \fIoptions\fR argument, whose
+unused bits must be zero. However, if a pattern was compiled with
+PCRE_ANCHORED, or turned out to be anchored by virtue of its contents, it
+cannot be made unachored at matching time.
+
+There are also three further options that can be set only at matching time:
+
+ PCRE_NOTBOL
+
+The first character of the string is not the beginning of a line, so the
+circumflex metacharacter should not match before it. Setting this without
+PCRE_MULTILINE (at compile time) causes circumflex never to match.
+
+ PCRE_NOTEOL
+
+The end of the string is not the end of a line, so the dollar metacharacter
+should not match it nor (except in multiline mode) a newline immediately before
+it. Setting this without PCRE_MULTILINE (at compile time) causes dollar never
+to match.
+
+ PCRE_NOTEMPTY
+
+An empty string is not considered to be a valid match if this option is set. If
+there are alternatives in the pattern, they are tried. If all the alternatives
+match the empty string, the entire match fails. For example, if the pattern
+
+ a?b?
+
+is applied to a string not beginning with "a" or "b", it matches the empty
+string at the start of the subject. With PCRE_NOTEMPTY set, this match is not
+valid, so PCRE searches further into the string for occurrences of "a" or "b".
+
+Perl has no direct equivalent of PCRE_NOTEMPTY, but it does make a special case
+of a pattern match of the empty string within its \fBsplit()\fR function, and
+when using the /g modifier. It is possible to emulate Perl's behaviour after
+matching a null string by first trying the match again at the same offset with
+PCRE_NOTEMPTY set, and then if that fails by advancing the starting offset (see
+below) and trying an ordinary match again.
+
+The subject string is passed as a pointer in \fIsubject\fR, a length in
+\fIlength\fR, and a starting offset in \fIstartoffset\fR. Unlike the pattern
+string, it may contain binary zero characters. When the starting offset is
+zero, the search for a match starts at the beginning of the subject, and this
+is by far the most common case.
+
+A non-zero starting offset is useful when searching for another match in the
+same subject by calling \fBpcre_exec()\fR again after a previous success.
+Setting \fIstartoffset\fR differs from just passing over a shortened string and
+setting PCRE_NOTBOL in the case of a pattern that begins with any kind of
+lookbehind. For example, consider the pattern
+
+ \\Biss\\B
+
+which finds occurrences of "iss" in the middle of words. (\\B matches only if
+the current position in the subject is not a word boundary.) When applied to
+the string "Mississipi" the first call to \fBpcre_exec()\fR finds the first
+occurrence. If \fBpcre_exec()\fR is called again with just the remainder of the
+subject, namely "issipi", it does not match, because \\B is always false at the
+start of the subject, which is deemed to be a word boundary. However, if
+\fBpcre_exec()\fR is passed the entire string again, but with \fIstartoffset\fR
+set to 4, it finds the second occurrence of "iss" because it is able to look
+behind the starting point to discover that it is preceded by a letter.
+
+If a non-zero starting offset is passed when the pattern is anchored, one
+attempt to match at the given offset is tried. This can only succeed if the
+pattern does not require the match to be at the start of the subject.
+
+In general, a pattern matches a certain portion of the subject, and in
+addition, further substrings from the subject may be picked out by parts of the
+pattern. Following the usage in Jeffrey Friedl's book, this is called
+"capturing" in what follows, and the phrase "capturing subpattern" is used for
+a fragment of a pattern that picks out a substring. PCRE supports several other
+kinds of parenthesized subpattern that do not cause substrings to be captured.
+
+Captured substrings are returned to the caller via a vector of integer offsets
+whose address is passed in \fIovector\fR. The number of elements in the vector
+is passed in \fIovecsize\fR. The first two-thirds of the vector is used to pass
+back captured substrings, each substring using a pair of integers. The
+remaining third of the vector is used as workspace by \fBpcre_exec()\fR while
+matching capturing subpatterns, and is not available for passing back
+information. The length passed in \fIovecsize\fR should always be a multiple of
+three. If it is not, it is rounded down.
+
+When a match has been successful, information about captured substrings is
+returned in pairs of integers, starting at the beginning of \fIovector\fR, and
+continuing up to two-thirds of its length at the most. The first element of a
+pair is set to the offset of the first character in a substring, and the second
+is set to the offset of the first character after the end of a substring. The
+first pair, \fIovector[0]\fR and \fIovector[1]\fR, identify the portion of the
+subject string matched by the entire pattern. The next pair is used for the
+first capturing subpattern, and so on. The value returned by \fBpcre_exec()\fR
+is the number of pairs that have been set. If there are no capturing
+subpatterns, the return value from a successful match is 1, indicating that
+just the first pair of offsets has been set.
+
+Some convenience functions are provided for extracting the captured substrings
+as separate strings. These are described in the following section.
+
+It is possible for an capturing subpattern number \fIn+1\fR to match some
+part of the subject when subpattern \fIn\fR has not been used at all. For
+example, if the string "abc" is matched against the pattern (a|(z))(bc)
+subpatterns 1 and 3 are matched, but 2 is not. When this happens, both offset
+values corresponding to the unused subpattern are set to -1.
+
+If a capturing subpattern is matched repeatedly, it is the last portion of the
+string that it matched that gets returned.
+
+If the vector is too small to hold all the captured substrings, it is used as
+far as possible (up to two-thirds of its length), and the function returns a
+value of zero. In particular, if the substring offsets are not of interest,
+\fBpcre_exec()\fR may be called with \fIovector\fR passed as NULL and
+\fIovecsize\fR as zero. However, if the pattern contains back references and
+the \fIovector\fR isn't big enough to remember the related substrings, PCRE has
+to get additional memory for use during matching. Thus it is usually advisable
+to supply an \fIovector\fR.
+
+Note that \fBpcre_info()\fR can be used to find out how many capturing
+subpatterns there are in a compiled pattern. The smallest size for
+\fIovector\fR that will allow for \fIn\fR captured substrings in addition to
+the offsets of the substring matched by the whole pattern is (\fIn\fR+1)*3.
+
+If \fBpcre_exec()\fR fails, it returns a negative number. The following are
+defined in the header file:
+
+ PCRE_ERROR_NOMATCH (-1)
+
+The subject string did not match the pattern.
+
+ PCRE_ERROR_NULL (-2)
+
+Either \fIcode\fR or \fIsubject\fR was passed as NULL, or \fIovector\fR was
+NULL and \fIovecsize\fR was not zero.
+
+ PCRE_ERROR_BADOPTION (-3)
+
+An unrecognized bit was set in the \fIoptions\fR argument.
+
+ PCRE_ERROR_BADMAGIC (-4)
+
+PCRE stores a 4-byte "magic number" at the start of the compiled code, to catch
+the case when it is passed a junk pointer. This is the error it gives when the
+magic number isn't present.
+
+ PCRE_ERROR_UNKNOWN_NODE (-5)
+
+While running the pattern match, an unknown item was encountered in the
+compiled pattern. This error could be caused by a bug in PCRE or by overwriting
+of the compiled pattern.
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+If a pattern contains back references, but the \fIovector\fR that is passed to
+\fBpcre_exec()\fR is not big enough to remember the referenced substrings, PCRE
+gets a block of memory at the start of matching to use for this purpose. If the
+call via \fBpcre_malloc()\fR fails, this error is given. The memory is freed at
+the end of matching.
+
+
+.SH EXTRACTING CAPTURED SUBSTRINGS
+Captured substrings can be accessed directly by using the offsets returned by
+\fBpcre_exec()\fR in \fIovector\fR. For convenience, the functions
+\fBpcre_copy_substring()\fR, \fBpcre_get_substring()\fR, and
+\fBpcre_get_substring_list()\fR are provided for extracting captured substrings
+as new, separate, zero-terminated strings. A substring that contains a binary
+zero is correctly extracted and has a further zero added on the end, but the
+result does not, of course, function as a C string.
+
+The first three arguments are the same for all three functions: \fIsubject\fR
+is the subject string which has just been successfully matched, \fIovector\fR
+is a pointer to the vector of integer offsets that was passed to
+\fBpcre_exec()\fR, and \fIstringcount\fR is the number of substrings that
+were captured by the match, including the substring that matched the entire
+regular expression. This is the value returned by \fBpcre_exec\fR if it
+is greater than zero. If \fBpcre_exec()\fR returned zero, indicating that it
+ran out of space in \fIovector\fR, the value passed as \fIstringcount\fR should
+be the size of the vector divided by three.
+
+The functions \fBpcre_copy_substring()\fR and \fBpcre_get_substring()\fR
+extract a single substring, whose number is given as \fIstringnumber\fR. A
+value of zero extracts the substring that matched the entire pattern, while
+higher values extract the captured substrings. For \fBpcre_copy_substring()\fR,
+the string is placed in \fIbuffer\fR, whose length is given by
+\fIbuffersize\fR, while for \fBpcre_get_substring()\fR a new block of memory is
+obtained via \fBpcre_malloc\fR, and its address is returned via
+\fIstringptr\fR. The yield of the function is the length of the string, not
+including the terminating zero, or one of
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+The buffer was too small for \fBpcre_copy_substring()\fR, or the attempt to get
+memory failed for \fBpcre_get_substring()\fR.
+
+ PCRE_ERROR_NOSUBSTRING (-7)
+
+There is no substring whose number is \fIstringnumber\fR.
+
+The \fBpcre_get_substring_list()\fR function extracts all available substrings
+and builds a list of pointers to them. All this is done in a single block of
+memory which is obtained via \fBpcre_malloc\fR. The address of the memory block
+is returned via \fIlistptr\fR, which is also the start of the list of string
+pointers. The end of the list is marked by a NULL pointer. The yield of the
+function is zero if all went well, or
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+if the attempt to get the memory block failed.
+
+When any of these functions encounter a substring that is unset, which can
+happen when capturing subpattern number \fIn+1\fR matches some part of the
+subject, but subpattern \fIn\fR has not been used at all, they return an empty
+string. This can be distinguished from a genuine zero-length substring by
+inspecting the appropriate offset in \fIovector\fR, which is negative for unset
+substrings.
+
+The two convenience functions \fBpcre_free_substring()\fR and
+\fBpcre_free_substring_list()\fR can be used to free the memory returned by
+a previous call of \fBpcre_get_substring()\fR or
+\fBpcre_get_substring_list()\fR, respectively. They do nothing more than call
+the function pointed to by \fBpcre_free\fR, which of course could be called
+directly from a C program. However, PCRE is used in some situations where it is
+linked via a special interface to another programming language which cannot use
+\fBpcre_free\fR directly; it is for these cases that the functions are
+provided.
+
+
+.SH LIMITATIONS
+There are some size limitations in PCRE but it is hoped that they will never in
+practice be relevant.
+The maximum length of a compiled pattern is 65539 (sic) bytes.
+All values in repeating quantifiers must be less than 65536.
+The maximum number of capturing subpatterns is 99.
+The maximum number of all parenthesized subpatterns, including capturing
+subpatterns, assertions, and other types of subpattern, is 200.
+
+The maximum length of a subject string is the largest positive number that an
+integer variable can hold. However, PCRE uses recursion to handle subpatterns
+and indefinite repetition. This means that the available stack space may limit
+the size of a subject string that can be processed by certain patterns.
+
+
+.SH DIFFERENCES FROM PERL
+The differences described here are with respect to Perl 5.005.
+
+1. By default, a whitespace character is any character that the C library
+function \fBisspace()\fR recognizes, though it is possible to compile PCRE with
+alternative character type tables. Normally \fBisspace()\fR matches space,
+formfeed, newline, carriage return, horizontal tab, and vertical tab. Perl 5
+no longer includes vertical tab in its set of whitespace characters. The \\v
+escape that was in the Perl documentation for a long time was never in fact
+recognized. However, the character itself was treated as whitespace at least
+up to 5.002. In 5.004 and 5.005 it does not match \\s.
+
+2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl permits
+them, but they do not mean what you might think. For example, (?!a){3} does
+not assert that the next three characters are not "a". It just asserts that the
+next character is not "a" three times.
+
+3. Capturing subpatterns that occur inside negative lookahead assertions are
+counted, but their entries in the offsets vector are never set. Perl sets its
+numerical variables from any such patterns that are matched before the
+assertion fails to match something (thereby succeeding), but only if the
+negative lookahead assertion contains just one branch.
+
+4. Though binary zero characters are supported in the subject string, they are
+not allowed in a pattern string because it is passed as a normal C string,
+terminated by zero. The escape sequence "\\0" can be used in the pattern to
+represent a binary zero.
+
+5. The following Perl escape sequences are not supported: \\l, \\u, \\L, \\U,
+\\E, \\Q. In fact these are implemented by Perl's general string-handling and
+are not part of its pattern matching engine.
+
+6. The Perl \\G assertion is not supported as it is not relevant to single
+pattern matches.
+
+7. Fairly obviously, PCRE does not support the (?{code}) and (?p{code})
+constructions. However, there is some experimental support for recursive
+patterns using the non-Perl item (?R).
+
+8. There are at the time of writing some oddities in Perl 5.005_02 concerned
+with the settings of captured strings when part of a pattern is repeated. For
+example, matching "aba" against the pattern /^(a(b)?)+$/ sets $2 to the value
+"b", but matching "aabbaa" against /^(aa(bb)?)+$/ leaves $2 unset. However, if
+the pattern is changed to /^(aa(b(b))?)+$/ then $2 (and $3) are set.
+
+In Perl 5.004 $2 is set in both cases, and that is also true of PCRE. If in the
+future Perl changes to a consistent state that is different, PCRE may change to
+follow.
+
+9. Another as yet unresolved discrepancy is that in Perl 5.005_02 the pattern
+/^(a)?(?(1)a|b)+$/ matches the string "a", whereas in PCRE it does not.
+However, in both Perl and PCRE /^(a)?a/ matched against "a" leaves $1 unset.
+
+10. PCRE provides some extensions to the Perl regular expression facilities:
+
+(a) Although lookbehind assertions must match fixed length strings, each
+alternative branch of a lookbehind assertion can match a different length of
+string. Perl 5.005 requires them all to have the same length.
+
+(b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not set, the $ meta-
+character matches only at the very end of the string.
+
+(c) If PCRE_EXTRA is set, a backslash followed by a letter with no special
+meaning is faulted.
+
+(d) If PCRE_UNGREEDY is set, the greediness of the repetition quantifiers is
+inverted, that is, by default they are not greedy, but if followed by a
+question mark they are.
+
+(e) PCRE_ANCHORED can be used to force a pattern to be tried only at the start
+of the subject.
+
+(f) The PCRE_NOTBOL, PCRE_NOTEOL, and PCRE_NOTEMPTY options for
+\fBpcre_exec()\fR have no Perl equivalents.
+
+(g) The (?R) construct allows for recursive pattern matching (Perl 5.6 can do
+this using the (?p{code}) construct, which PCRE cannot of course support.)
+
+
+.SH REGULAR EXPRESSION DETAILS
+The syntax and semantics of the regular expressions supported by PCRE are
+described below. Regular expressions are also described in the Perl
+documentation and in a number of other books, some of which have copious
+examples. Jeffrey Friedl's "Mastering Regular Expressions", published by
+O'Reilly (ISBN 1-56592-257), covers them in great detail.
+
+The description here is intended as reference documentation. The basic
+operation of PCRE is on strings of bytes. However, there is the beginnings of
+some support for UTF-8 character strings. To use this support you must
+configure PCRE to include it, and then call \fBpcre_compile()\fR with the
+PCRE_UTF8 option. How this affects the pattern matching is described in the
+final section of this document.
+
+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+
+ The quick brown fox
+
+matches a portion of a subject string that is identical to itself. The power of
+regular expressions comes from the ability to include alternatives and
+repetitions in the pattern. These are encoded in the pattern by the use of
+\fImeta-characters\fR, which do not stand for themselves but instead are
+interpreted in some special way.
+
+There are two different sets of meta-characters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized in square brackets. Outside square brackets, the meta-characters are
+as follows:
+
+ \\ general escape character with several uses
+ ^ assert start of subject (or line, in multiline mode)
+ $ assert end of subject (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ { start min/max quantifier
+
+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only meta-characters are:
+
+ \\ general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+ ] terminates the character class
+
+The following sections describe the use of each of the meta-characters.
+
+
+.SH BACKSLASH
+The backslash character has several uses. Firstly, if it is followed by a
+non-alphameric character, it takes away any special meaning that character may
+have. This use of backslash as an escape character applies both inside and
+outside character classes.
+
+For example, if you want to match a "*" character, you write "\\*" in the
+pattern. This applies whether or not the following character would otherwise be
+interpreted as a meta-character, so it is always safe to precede a
+non-alphameric with "\\" to specify that it stands for itself. In particular,
+if you want to match a backslash, you write "\\\\".
+
+If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the
+pattern (other than in a character class) and characters between a "#" outside
+a character class and the next newline character are ignored. An escaping
+backslash can be used to include a whitespace or "#" character as part of the
+pattern.
+
+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters, apart from the binary zero that terminates a pattern,
+but when a pattern is being prepared by text editing, it is usually easier to
+use one of the following escape sequences than the binary character it
+represents:
+
+ \\a alarm, that is, the BEL character (hex 07)
+ \\cx "control-x", where x is any character
+ \\e escape (hex 1B)
+ \\f formfeed (hex 0C)
+ \\n newline (hex 0A)
+ \\r carriage return (hex 0D)
+ \\t tab (hex 09)
+ \\xhh character with hex code hh
+ \\ddd character with octal code ddd, or backreference
+
+The precise effect of "\\cx" is as follows: if "x" is a lower case letter, it
+is converted to upper case. Then bit 6 of the character (hex 40) is inverted.
+Thus "\\cz" becomes hex 1A, but "\\c{" becomes hex 3B, while "\\c;" becomes hex
+7B.
+
+After "\\x", up to two hexadecimal digits are read (letters can be in upper or
+lower case).
+
+After "\\0" up to two further octal digits are read. In both cases, if there
+are fewer than two digits, just those that are present are used. Thus the
+sequence "\\0\\x\\07" specifies two binary zeros followed by a BEL character.
+Make sure you supply two digits after the initial zero if the character that
+follows is itself an octal digit.
+
+The handling of a backslash followed by a digit other than 0 is complicated.
+Outside a character class, PCRE reads it and any following digits as a decimal
+number. If the number is less than 10, or if there have been at least that many
+previous capturing left parentheses in the expression, the entire sequence is
+taken as a \fIback reference\fR. A description of how this works is given
+later, following the discussion of parenthesized subpatterns.
+
+Inside a character class, or if the decimal number is greater than 9 and there
+have not been that many capturing subpatterns, PCRE re-reads up to three octal
+digits following the backslash, and generates a single byte from the least
+significant 8 bits of the value. Any subsequent digits stand for themselves.
+For example:
+
+ \\040 is another way of writing a space
+ \\40 is the same, provided there are fewer than 40
+ previous capturing subpatterns
+ \\7 is always a back reference
+ \\11 might be a back reference, or another way of
+ writing a tab
+ \\011 is always a tab
+ \\0113 is a tab followed by the character "3"
+ \\113 is the character with octal code 113 (since there
+ can be no more than 99 back references)
+ \\377 is a byte consisting entirely of 1 bits
+ \\81 is either a back reference, or a binary zero
+ followed by the two characters "8" and "1"
+
+Note that octal values of 100 or greater must not be introduced by a leading
+zero, because no more than three octal digits are ever read.
+
+All the sequences that define a single byte value can be used both inside and
+outside character classes. In addition, inside a character class, the sequence
+"\\b" is interpreted as the backspace character (hex 08). Outside a character
+class it has a different meaning (see below).
+
+The third use of backslash is for specifying generic character types:
+
+ \\d any decimal digit
+ \\D any character that is not a decimal digit
+ \\s any whitespace character
+ \\S any character that is not a whitespace character
+ \\w any "word" character
+ \\W any "non-word" character
+
+Each pair of escape sequences partitions the complete set of characters into
+two disjoint sets. Any given character matches one, and only one, of each pair.
+
+A "word" character is any letter or digit or the underscore character, that is,
+any character which can be part of a Perl "word". The definition of letters and
+digits is controlled by PCRE's character tables, and may vary if locale-
+specific matching is taking place (see "Locale support" above). For example, in
+the "fr" (French) locale, some character codes greater than 128 are used for
+accented letters, and these are matched by \\w.
+
+These character type sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, since
+there is no character to match.
+
+The fourth use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+subpatterns for more complicated assertions is described below. The backslashed
+assertions are
+
+ \\b word boundary
+ \\B not a word boundary
+ \\A start of subject (independent of multiline mode)
+ \\Z end of subject or newline at end (independent of multiline mode)
+ \\z end of subject (independent of multiline mode)
+
+These assertions may not appear in character classes (but note that "\\b" has a
+different meaning, namely the backspace character, inside a character class).
+
+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \\w or \\W (i.e. one matches
+\\w and the other matches \\W), or the start or end of the string if the
+first or last character matches \\w, respectively.
+
+The \\A, \\Z, and \\z assertions differ from the traditional circumflex and
+dollar (described below) in that they only ever match at the very start and end
+of the subject string, whatever options are set. They are not affected by the
+PCRE_NOTBOL or PCRE_NOTEOL options. If the \fIstartoffset\fR argument of
+\fBpcre_exec()\fR is non-zero, \\A can never match. The difference between \\Z
+and \\z is that \\Z matches before a newline that is the last character of the
+string as well as at the end of the string, whereas \\z matches only at the
+end.
+
+
+.SH CIRCUMFLEX AND DOLLAR
+Outside a character class, in the default matching mode, the circumflex
+character is an assertion which is true only if the current matching point is
+at the start of the subject string. If the \fIstartoffset\fR argument of
+\fBpcre_exec()\fR is non-zero, circumflex can never match. Inside a character
+class, circumflex has an entirely different meaning (see below).
+
+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+
+A dollar character is an assertion which is true only if the current matching
+point is at the end of the subject string, or immediately before a newline
+character that is the last character in the string (by default). Dollar need
+not be the last character of the pattern if a number of alternatives are
+involved, but it should be the last item in any branch in which it appears.
+Dollar has no special meaning in a character class.
+
+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE_DOLLAR_ENDONLY option at compile or matching
+time. This does not affect the \\Z assertion.
+
+The meanings of the circumflex and dollar characters are changed if the
+PCRE_MULTILINE option is set. When this is the case, they match immediately
+after and immediately before an internal "\\n" character, respectively, in
+addition to matching at the start and end of the subject string. For example,
+the pattern /^abc$/ matches the subject string "def\\nabc" in multiline mode,
+but not otherwise. Consequently, patterns that are anchored in single line mode
+because all branches start with "^" are not anchored in multiline mode, and a
+match for circumflex is possible when the \fIstartoffset\fR argument of
+\fBpcre_exec()\fR is non-zero. The PCRE_DOLLAR_ENDONLY option is ignored if
+PCRE_MULTILINE is set.
+
+Note that the sequences \\A, \\Z, and \\z can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\\A is it always anchored, whether PCRE_MULTILINE is set or not.
+
+
+.SH FULL STOP (PERIOD, DOT)
+Outside a character class, a dot in the pattern matches any one character in
+the subject, including a non-printing character, but not (by default) newline.
+If the PCRE_DOTALL option is set, dots match newlines as well. The handling of
+dot is entirely independent of the handling of circumflex and dollar, the only
+relationship being that they both involve newline characters. Dot has no
+special meaning in a character class.
+
+
+.SH SQUARE BRACKETS
+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special. If a
+closing square bracket is required as a member of the class, it should be the
+first data character in the class (after an initial circumflex, if present) or
+escaped with a backslash.
+
+A character class matches a single character in the subject; the character must
+be in the set of characters defined by the class, unless the first character in
+the class is a circumflex, in which case the subject character must not be in
+the set defined by the class. If a circumflex is actually required as a member
+of the class, ensure it is not the first character, or escape it with a
+backslash.
+
+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters which
+are in the class by enumerating those that are not. It is not an assertion: it
+still consumes a character from the subject string, and fails if the current
+pointer is at the end of the string.
+
+When caseless matching is set, any letters in a class represent both their
+upper case and lower case versions, so for example, a caseless [aeiou] matches
+"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
+caseful version would.
+
+The newline character is never treated in any special way in character classes,
+whatever the setting of the PCRE_DOTALL or PCRE_MULTILINE options is. A class
+such as [^a] will always match a newline.
+
+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class.
+
+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\\]46] is interpreted as a single class containing a
+range followed by two separate characters. The octal or hexadecimal
+representation of "]" can also be used to end a range.
+
+Ranges operate in ASCII collating sequence. They can also be used for
+characters specified numerically, for example [\\000-\\037]. If a range that
+includes letters is used when caseless matching is set, it matches the letters
+in either case. For example, [W-c] is equivalent to [][\\^_`wxyzabc], matched
+caselessly, and if character tables for the "fr" locale are in use,
+[\\xc8-\\xcb] matches accented E characters in both cases.
+
+The character types \\d, \\D, \\s, \\S, \\w, and \\W may also appear in a
+character class, and add the characters that they match to the class. For
+example, [\\dABCDEF] matches any hexadecimal digit. A circumflex can
+conveniently be used with the upper case character types to specify a more
+restricted set of characters than the matching lower case type. For example,
+the class [^\\W_] matches any letter or digit, but not underscore.
+
+All non-alphameric characters other than \\, -, ^ (at the start) and the
+terminating ] are non-special in character classes, but it does no harm if they
+are escaped.
+
+
+.SH POSIX CHARACTER CLASSES
+Perl 5.6 (not yet released at the time of writing) is going to support the
+POSIX notation for character classes, which uses names enclosed by [: and :]
+within the enclosing square brackets. PCRE supports this notation. For example,
+
+ [01[:alpha:]%]
+
+matches "0", "1", any alphabetic character, or "%". The supported class names
+are
+
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ cntrl control characters
+ digit decimal digits (same as \\d)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits
+ space white space (same as \\s)
+ upper upper case letters
+ word "word" characters (same as \\w)
+ xdigit hexadecimal digits
+
+The names "ascii" and "word" are Perl extensions. Another Perl extension is
+negation, which is indicated by a ^ character after the colon. For example,
+
+ [12[:^digit:]]
+
+matches "1", "2", or any non-digit. PCRE (and Perl) also recogize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+
+
+.SH VERTICAL BAR
+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+
+ gilbert|sullivan
+
+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string).
+The matching process tries each alternative in turn, from left to right,
+and the first one that succeeds is used. If the alternatives are within a
+subpattern (defined below), "succeeds" means matching the rest of the main
+pattern as well as the alternative in the subpattern.
+
+
+.SH INTERNAL OPTION SETTING
+The settings of PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and PCRE_EXTENDED
+can be changed from within the pattern by a sequence of Perl option letters
+enclosed between "(?" and ")". The option letters are
+
+ i for PCRE_CASELESS
+ m for PCRE_MULTILINE
+ s for PCRE_DOTALL
+ x for PCRE_EXTENDED
+
+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the letter with a hyphen, and a combined
+setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and
+PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also
+permitted. If a letter appears both before and after the hyphen, the option is
+unset.
+
+The scope of these option changes depends on where in the pattern the setting
+occurs. For settings that are outside any subpattern (defined below), the
+effect is the same as if the options were set or unset at the start of
+matching. The following patterns all behave in exactly the same way:
+
+ (?i)abc
+ a(?i)bc
+ ab(?i)c
+ abc(?i)
+
+which in turn is the same as compiling the pattern abc with PCRE_CASELESS set.
+In other words, such "top level" settings apply to the whole pattern (unless
+there are other changes inside subpatterns). If there is more than one setting
+of the same option at top level, the rightmost setting is used.
+
+If an option change occurs inside a subpattern, the effect is different. This
+is a change of behaviour in Perl 5.005. An option change inside a subpattern
+affects only that part of the subpattern that follows it, so
+
+ (a(?i)b)c
+
+matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used).
+By this means, options can be made to have different settings in different
+parts of the pattern. Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern. For example,
+
+ (a(?i)b|c)
+
+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+
+The PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA can be changed in the
+same way as the Perl-compatible options by using the characters U and X
+respectively. The (?X) flag setting is special in that it must always occur
+earlier in the pattern than any of the additional features it turns on, even
+when it is at top level. It is best put at the start.
+
+
+.SH SUBPATTERNS
+Subpatterns are delimited by parentheses (round brackets), which can be nested.
+Marking part of a pattern as a subpattern does two things:
+
+1. It localizes a set of alternatives. For example, the pattern
+
+ cat(aract|erpillar|)
+
+matches one of the words "cat", "cataract", or "caterpillar". Without the
+parentheses, it would match "cataract", "erpillar" or the empty string.
+
+2. It sets up the subpattern as a capturing subpattern (as defined above).
+When the whole pattern matches, that portion of the subject string that matched
+the subpattern is passed back to the caller via the \fIovector\fR argument of
+\fBpcre_exec()\fR. Opening parentheses are counted from left to right (starting
+from 1) to obtain the numbers of the capturing subpatterns.
+
+For example, if the string "the red king" is matched against the pattern
+
+ the ((red|white) (king|queen))
+
+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3.
+
+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when a grouping subpattern is required without a
+capturing requirement. If an opening parenthesis is followed by "?:", the
+subpattern does not do any capturing, and is not counted when computing the
+number of any subsequent capturing subpatterns. For example, if the string "the
+white queen" is matched against the pattern
+
+ the ((?:red|white) (king|queen))
+
+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of captured substrings is 99, and the maximum number of
+all subpatterns, both capturing and non-capturing, is 200.
+
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern, the option letters may appear between the "?" and
+the ":". Thus the two patterns
+
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+
+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the subpattern
+is reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+
+
+.SH REPETITION
+Repetition is specified by quantifiers, which can follow any of the following
+items:
+
+ a single character, possibly escaped
+ the . metacharacter
+ a character class
+ a back reference (see next section)
+ a parenthesized subpattern (unless it is an assertion - see below)
+
+The general repetition quantifier specifies a minimum and maximum number of
+permitted matches, by giving the two numbers in curly brackets (braces),
+separated by a comma. The numbers must be less than 65536, and the first must
+be less than or equal to the second. For example:
+
+ z{2,4}
+
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+
+ [aeiou]{3,}
+
+matches at least 3 successive vowels, but may match many more, while
+
+ \\d{8}
+
+matches exactly 8 digits. An opening curly bracket that appears in a position
+where a quantifier is not allowed, or one that does not match the syntax of a
+quantifier, is taken as a literal character. For example, {,6} is not a
+quantifier, but a literal string of four characters.
+
+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present.
+
+For convenience (and historical compatibility) the three most common
+quantifiers have single-character abbreviations:
+
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+
+It is possible to construct infinite loops by following a subpattern that can
+match no characters with a quantifier that has no upper limit, for example:
+
+ (a?)*
+
+Earlier versions of Perl and PCRE used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but if any repetition of the subpattern does in fact
+match no characters, the loop is forcibly broken.
+
+By default, the quantifiers are "greedy", that is, they match as much as
+possible (up to the maximum number of permitted times), without causing the
+rest of the pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between the
+sequences /* and */ and within the sequence, individual * and / characters may
+appear. An attempt to match C comments by applying the pattern
+
+ /\\*.*\\*/
+
+to the string
+
+ /* first command */ not comment /* second comment */
+
+fails, because it matches the entire string owing to the greediness of the .*
+item.
+
+However, if a quantifier is followed by a question mark, it ceases to be
+greedy, and instead matches the minimum number of times possible, so the
+pattern
+
+ /\\*.*?\\*/
+
+does the right thing with the C comments. The meaning of the various
+quantifiers is not otherwise changed, just the preferred number of matches.
+Do not confuse this use of question mark with its use as a quantifier in its
+own right. Because it has two uses, it can sometimes appear doubled, as in
+
+ \\d??\\d
+
+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+
+If the PCRE_UNGREEDY option is set (an option which is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+
+When a parenthesized subpattern is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more store is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+
+If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the . to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE treats such a pattern as
+though it were preceded by \\A. In cases where it is known that the subject
+string contains no newlines, it is worth setting PCRE_DOTALL when the pattern
+begins with .* in order to obtain this optimization, or alternatively using ^
+to indicate anchoring explicitly.
+
+When a capturing subpattern is repeated, the value captured is the substring
+that matched the final iteration. For example, after
+
+ (tweedle[dume]{3}\\s*)+
+
+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capturing subpatterns, the
+corresponding captured values may have been set in previous iterations. For
+example, after
+
+ /(a|(b))+/
+
+matches "aba" the value of the second captured substring is "b".
+
+
+.SH BACK REFERENCES
+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a back reference to a capturing subpattern earlier
+(i.e. to its left) in the pattern, provided there have been that many previous
+capturing left parentheses.
+
+However, if the decimal number following the backslash is less than 10, it is
+always taken as a back reference, and causes an error only if there are not
+that many capturing left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of the reference for
+numbers less than 10. See the section entitled "Backslash" above for further
+details of the handling of digits following a backslash.
+
+A back reference matches whatever actually matched the capturing subpattern in
+the current subject string, rather than anything matching the subpattern
+itself. So the pattern
+
+ (sens|respons)e and \\1ibility
+
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+back reference, the case of letters is relevant. For example,
+
+ ((?i)rah)\\s+\\1
+
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capturing subpattern is matched caselessly.
+
+There may be more than one back reference to the same subpattern. If a
+subpattern has not actually been used in a particular match, any back
+references to it always fail. For example, the pattern
+
+ (a|(bc))\\2
+
+always fails if it starts to match "a" rather than "bc". Because there may be
+up to 99 back references, all digits following the backslash are taken
+as part of a potential back reference number. If the pattern continues with a
+digit character, some delimiter must be used to terminate the back reference.
+If the PCRE_EXTENDED option is set, this can be whitespace. Otherwise an empty
+comment can be used.
+
+A back reference that occurs inside the parentheses to which it refers fails
+when the subpattern is first used, so, for example, (a\\1) never matches.
+However, such references can be useful inside repeated subpatterns. For
+example, the pattern
+
+ (a|b\\1)+
+
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the subpattern, the back reference matches the character string corresponding
+to the previous iteration. In order for this to work, the pattern must be such
+that the first iteration does not need to match the back reference. This can be
+done using alternation, as in the example above, or by a quantifier with a
+minimum of zero.
+
+
+.SH ASSERTIONS
+An assertion is a test on the characters following or preceding the current
+matching point that does not actually consume any characters. The simple
+assertions coded as \\b, \\B, \\A, \\Z, \\z, ^ and $ are described above. More
+complicated assertions are coded as subpatterns. There are two kinds: those
+that look ahead of the current position in the subject string, and those that
+look behind it.
+
+An assertion subpattern is matched in the normal way, except that it does not
+cause the current matching position to be changed. Lookahead assertions start
+with (?= for positive assertions and (?! for negative assertions. For example,
+
+ \\w+(?=;)
+
+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+
+ foo(?!bar)
+
+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+
+ (?!foo)bar
+
+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve this effect.
+
+Lookbehind assertions start with (?<= for positive assertions and (?<! for
+negative assertions. For example,
+
+ (?<!foo)bar
+
+does find an occurrence of "bar" that is not preceded by "foo". The contents of
+a lookbehind assertion are restricted such that all the strings it matches must
+have a fixed length. However, if there are several alternatives, they do not
+all have to have the same fixed length. Thus
+
+ (?<=bullock|donkey)
+
+is permitted, but
+
+ (?<!dogs?|cats?)
+
+causes an error at compile time. Branches that match different length strings
+are permitted only at the top level of a lookbehind assertion. This is an
+extension compared with Perl 5.005, which requires all branches to match the
+same length of string. An assertion such as
+
+ (?<=ab(c|de))
+
+is not permitted, because its single top-level branch can match two different
+lengths, but it is acceptable if rewritten to use two top-level branches:
+
+ (?<=abc|abde)
+
+The implementation of lookbehind assertions is, for each alternative, to
+temporarily move the current position back by the fixed width and then try to
+match. If there are insufficient characters before the current position, the
+match is deemed to fail. Lookbehinds in conjunction with once-only subpatterns
+can be particularly useful for matching at the ends of strings; an example is
+given at the end of the section on once-only subpatterns.
+
+Several assertions (of any sort) may occur in succession. For example,
+
+ (?<=\\d{3})(?<!999)foo
+
+matches "foo" preceded by three digits that are not "999". Notice that each of
+the assertions is applied independently at the same point in the subject
+string. First there is a check that the previous three characters are all
+digits, and then there is a check that the same three characters are not "999".
+This pattern does \fInot\fR match "foo" preceded by six characters, the first
+of which are digits and the last three of which are not "999". For example, it
+doesn't match "123abcfoo". A pattern to do that is
+
+ (?<=\\d{3}...)(?<!999)foo
+
+This time the first assertion looks at the preceding six characters, checking
+that the first three are digits, and then the second assertion checks that the
+preceding three characters are not "999".
+
+Assertions can be nested in any combination. For example,
+
+ (?<=(?<!foo)bar)baz
+
+matches an occurrence of "baz" that is preceded by "bar" which in turn is not
+preceded by "foo", while
+
+ (?<=\\d{3}(?!999)...)foo
+
+is another pattern which matches "foo" preceded by three digits and any three
+characters that are not "999".
+
+Assertion subpatterns are not capturing subpatterns, and may not be repeated,
+because it makes no sense to assert the same thing several times. If any kind
+of assertion contains capturing subpatterns within it, these are counted for
+the purposes of numbering the capturing subpatterns in the whole pattern.
+However, substring capturing is carried out only for positive assertions,
+because it does not make sense for negative assertions.
+
+Assertions count towards the maximum of 200 parenthesized subpatterns.
+
+
+.SH ONCE-ONLY SUBPATTERNS
+With both maximizing and minimizing repetition, failure of what follows
+normally causes the repeated item to be re-evaluated to see if a different
+number of repeats allows the rest of the pattern to match. Sometimes it is
+useful to prevent this, either to change the nature of the match, or to cause
+it fail earlier than it otherwise might, when the author of the pattern knows
+there is no point in carrying on.
+
+Consider, for example, the pattern \\d+foo when applied to the subject line
+
+ 123456bar
+
+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \\d+
+item, and then with 4, and so on, before ultimately failing. Once-only
+subpatterns provide the means for specifying that once a portion of the pattern
+has matched, it is not to be re-evaluated in this way, so the matcher would
+give up immediately on failing to match "foo" the first time. The notation is
+another kind of special parenthesis, starting with (?> as in this example:
+
+ (?>\\d+)bar
+
+This kind of parenthesis "locks up" the part of the pattern it contains once
+it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+
+An alternative description is that a subpattern of this type matches the string
+of characters that an identical standalone pattern would match, if anchored at
+the current point in the subject string.
+
+Once-only subpatterns are not capturing subpatterns. Simple cases such as the
+above example can be thought of as a maximizing repeat that must swallow
+everything it can. So, while both \\d+ and \\d+? are prepared to adjust the
+number of digits they match in order to make the rest of the pattern match,
+(?>\\d+) can only match an entire sequence of digits.
+
+This construction can of course contain arbitrarily complicated subpatterns,
+and it can be nested.
+
+Once-only subpatterns can be used in conjunction with lookbehind assertions to
+specify efficient matching at the end of the subject string. Consider a simple
+pattern such as
+
+ abcd$
+
+when applied to a long string which does not match. Because matching proceeds
+from left to right, PCRE will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+
+ ^.*abcd$
+
+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+
+ ^(?>.*)(?<=abcd)
+
+there can be no backtracking for the .* item; it can match only the entire
+string. The subsequent lookbehind assertion does a single test on the last four
+characters. If it fails, the match fails immediately. For long strings, this
+approach makes a significant difference to the processing time.
+
+When a pattern contains an unlimited repeat inside a subpattern that can itself
+be repeated an unlimited number of times, the use of a once-only subpattern is
+the only way to avoid some failing matches taking a very long time indeed.
+The pattern
+
+ (\\D+|<\\d+>)*[!?]
+
+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+
+it takes a long time before reporting failure. This is because the string can
+be divided between the two repeats in a large number of ways, and all have to
+be tried. (The example used [!?] rather than a single character at the end,
+because both PCRE and Perl have an optimization that allows for fast failure
+when a single character is used. They remember the last single character that
+is required for a match, and fail early if it is not present in the string.)
+If the pattern is changed to
+
+ ((?>\\D+)|<\\d+>)*[!?]
+
+sequences of non-digits cannot be broken, and failure happens quickly.
+
+
+.SH CONDITIONAL SUBPATTERNS
+It is possible to cause the matching process to obey a subpattern
+conditionally or to choose between two alternative subpatterns, depending on
+the result of an assertion, or whether a previous capturing subpattern matched
+or not. The two possible forms of conditional subpattern are
+
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+
+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. If there are more than two alternatives in the
+subpattern, a compile-time error occurs.
+
+There are two kinds of condition. If the text between the parentheses consists
+of a sequence of digits, the condition is satisfied if the capturing subpattern
+of that number has previously matched. The number must be greater than zero.
+Consider the following pattern, which contains non-significant white space to
+make it more readable (assume the PCRE_EXTENDED option) and to divide it into
+three parts for ease of discussion:
+
+ ( \\( )? [^()]+ (?(1) \\) )
+
+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional subpattern that tests whether the first set of parentheses matched
+or not. If they did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing. In other words, this pattern matches a sequence of
+non-parentheses, optionally enclosed in parentheses.
+
+If the condition is not a sequence of digits, it must be an assertion. This may
+be a positive or negative lookahead or lookbehind assertion. Consider this
+pattern, again containing non-significant white space, and with the two
+alternatives on the second line:
+
+ (?(?=[^a-z]*[a-z])
+ \\d{2}-[a-z]{3}-\\d{2} | \\d{2}-\\d{2}-\\d{2} )
+
+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+
+
+.SH COMMENTS
+The sequence (?# marks the start of a comment which continues up to the next
+closing parenthesis. Nested parentheses are not permitted. The characters
+that make up a comment play no part in the pattern matching at all.
+
+If the PCRE_EXTENDED option is set, an unescaped # character outside a
+character class introduces a comment that continues up to the next newline
+character in the pattern.
+
+
+.SH RECURSIVE PATTERNS
+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth. Perl 5.6 has provided an
+experimental facility that allows regular expressions to recurse (amongst other
+things). It does this by interpolating Perl code in the expression at run time,
+and the code can refer to the expression itself. A Perl pattern to solve the
+parentheses problem can be created like this:
+
+ $re = qr{\\( (?: (?>[^()]+) | (?p{$re}) )* \\)}x;
+
+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears. Obviously, PCRE cannot support
+the interpolation of Perl code. Instead, the special item (?R) is provided for
+the specific case of recursion. This PCRE pattern solves the parentheses
+problem (assume the PCRE_EXTENDED option is set so that white space is
+ignored):
+
+ \\( ( (?>[^()]+) | (?R) )* \\)
+
+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (i.e. a correctly parenthesized substring). Finally
+there is a closing parenthesis.
+
+This particular example pattern contains nested unlimited repeats, and so the
+use of a once-only subpattern for matching strings of non-parentheses is
+important when applying the pattern to strings that do not match. For example,
+when it is applied to
+
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+
+it yields "no match" quickly. However, if a once-only subpattern is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+
+The values set for any capturing subpatterns are those from the outermost level
+of the recursion at which the subpattern value is set. If the pattern above is
+matched against
+
+ (ab(cd)ef)
+
+the value for the capturing parentheses is "ef", which is the last value taken
+on at the top level. If additional parentheses are added, giving
+
+ \\( ( ( (?>[^()]+) | (?R) )* ) \\)
+ ^ ^
+ ^ ^
+the string they capture is "ab(cd)ef", the contents of the top level
+parentheses. If there are more than 15 capturing parentheses in a pattern, PCRE
+has to obtain extra memory to store data during a recursion, which it does by
+using \fBpcre_malloc\fR, freeing it via \fBpcre_free\fR afterwards. If no
+memory can be obtained, it saves data for the first 15 capturing parentheses
+only, as there is no way to give an out-of-memory error from within a
+recursion.
+
+
+.SH PERFORMANCE
+Certain items that may appear in patterns are more efficient than others. It is
+more efficient to use a character class like [aeiou] than a set of alternatives
+such as (a|e|i|o|u). In general, the simplest construction that provides the
+required behaviour is usually the most efficient. Jeffrey Friedl's book
+contains a lot of discussion about optimizing regular expressions for efficient
+performance.
+
+When a pattern begins with .* and the PCRE_DOTALL option is set, the pattern is
+implicitly anchored by PCRE, since it can match only at the start of a subject
+string. However, if PCRE_DOTALL is not set, PCRE cannot make this optimization,
+because the . metacharacter does not then match a newline, and if the subject
+string contains newlines, the pattern may match from the character immediately
+following one of them instead of from the very start. For example, the pattern
+
+ (.*) second
+
+matches the subject "first\\nand second" (where \\n stands for a newline
+character) with the first captured substring being "and". In order to do this,
+PCRE has to retry the match starting after every newline in the subject.
+
+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE_DOTALL, or starting
+the pattern with ^.* to indicate explicit anchoring. That saves PCRE from
+having to scan along the subject looking for a newline to restart at.
+
+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+
+ (a+)*
+
+This can match "aaaa" in 33 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE has in principle to try every possible
+variation, and this can take an extremely long time.
+
+An optimization catches some of the more simple cases such as
+
+ (a+)*b
+
+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+
+ (a+)*\\d
+
+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+
+
+.SH UTF-8 SUPPORT
+Starting at release 3.3, PCRE has some support for character strings encoded
+in the UTF-8 format. This is incomplete, and is regarded as experimental. In
+order to use it, you must configure PCRE to include UTF-8 support in the code,
+and, in addition, you must call \fBpcre_compile()\fR with the PCRE_UTF8 option
+flag. When you do this, both the pattern and any subject strings that are
+matched against it are treated as UTF-8 strings instead of just strings of
+bytes, but only in the cases that are mentioned below.
+
+If you compile PCRE with UTF-8 support, but do not use it at run time, the
+library will be a bit bigger, but the additional run time overhead is limited
+to testing the PCRE_UTF8 flag in several places, so should not be very large.
+
+PCRE assumes that the strings it is given contain valid UTF-8 codes. It does
+not diagnose invalid UTF-8 strings. If you pass invalid UTF-8 strings to PCRE,
+the results are undefined.
+
+Running with PCRE_UTF8 set causes these changes in the way PCRE works:
+
+1. In a pattern, the escape sequence \\x{...}, where the contents of the braces
+is a string of hexadecimal digits, is interpreted as a UTF-8 character whose
+code number is the given hexadecimal number, for example: \\x{1234}. This
+inserts from one to six literal bytes into the pattern, using the UTF-8
+encoding. If a non-hexadecimal digit appears between the braces, the item is
+not recognized.
+
+2. The original hexadecimal escape sequence, \\xhh, generates a two-byte UTF-8
+character if its value is greater than 127.
+
+3. Repeat quantifiers are NOT correctly handled if they follow a multibyte
+character. For example, \\x{100}* and \\xc3+ do not work. If you want to
+repeat such characters, you must enclose them in non-capturing parentheses,
+for example (?:\\x{100}), at present.
+
+4. The dot metacharacter matches one UTF-8 character instead of a single byte.
+
+5. Unlike literal UTF-8 characters, the dot metacharacter followed by a
+repeat quantifier does operate correctly on UTF-8 characters instead of
+single bytes.
+
+4. Although the \\x{...} escape is permitted in a character class, characters
+whose values are greater than 255 cannot be included in a class.
+
+5. A class is matched against a UTF-8 character instead of just a single byte,
+but it can match only characters whose values are less than 256. Characters
+with greater values always fail to match a class.
+
+6. Repeated classes work correctly on multiple characters.
+
+7. Classes containing just a single character whose value is greater than 127
+(but less than 256), for example, [\\x80] or [^\\x{93}], do not work because
+these are optimized into single byte matches. In the first case, of course,
+the class brackets are just redundant.
+
+8. Lookbehind assertions move backwards in the subject by a fixed number of
+characters instead of a fixed number of bytes. Simple cases have been tested
+to work correctly, but there may be hidden gotchas herein.
+
+9. The character types such as \\d and \\w do not work correctly with UTF-8
+characters. They continue to test a single byte.
+
+10. Anything not explicitly mentioned here continues to work in bytes rather

+<LI><A NAME="SEC3" HREF="#TOC1">DESCRIPTION</A>
+<P>
+The PCRE library is a set of functions that implement regular expression
+pattern matching using the same syntax and semantics as Perl 5, with just a few
+differences (see below). The current implementation corresponds to Perl 5.005,
+with some additional features from later versions. This includes some
+experimental, incomplete support for UTF-8 encoded strings. Details of exactly
+what is and what is not supported are given below.
+</P>
+<P>
+PCRE has its own native API, which is described in this document. There is also
+a set of wrapper functions that correspond to the POSIX regular expression API.
+These are described in the <B>pcreposix</B> documentation.
+</P>
+<P>
+The native API function prototypes are defined in the header file <B>pcre.h</B>,
+and on Unix systems the library itself is called <B>libpcre.a</B>, so can be
+accessed by adding <B>-lpcre</B> to the command for linking an application which
+calls it. The header file defines the macros PCRE_MAJOR and PCRE_MINOR to
+contain the major and minor release numbers for the library. Applications can
+use these to include support for different releases.
+</P>
+<P>
+The functions <B>pcre_compile()</B>, <B>pcre_study()</B>, and <B>pcre_exec()</B>
+are used for compiling and matching regular expressions.
+</P>
+<P>
+The functions <B>pcre_copy_substring()</B>, <B>pcre_get_substring()</B>, and
+<B>pcre_get_substring_list()</B> are convenience functions for extracting
+captured substrings from a matched subject string; <B>pcre_free_substring()</B>
+and <B>pcre_free_substring_list()</B> are also provided, to free the memory used
+for extracted strings.
+</P>
+<P>
+The function <B>pcre_maketables()</B> is used (optionally) to build a set of
+character tables in the current locale for passing to <B>pcre_compile()</B>.
+</P>
+<P>
+The function <B>pcre_fullinfo()</B> is used to find out information about a
+compiled pattern; <B>pcre_info()</B> is an obsolete version which returns only
+some of the available information, but is retained for backwards compatibility.
+The function <B>pcre_version()</B> returns a pointer to a string containing the
+version of PCRE and its date of release.
+</P>
+<P>
+The global variables <B>pcre_malloc</B> and <B>pcre_free</B> initially contain
+the entry points of the standard <B>malloc()</B> and <B>free()</B> functions
+respectively. PCRE calls the memory management functions via these variables,
+so a calling program can replace them if it wishes to intercept the calls. This
+should be done before calling any PCRE functions.
+</P>
+<LI><A NAME="SEC4" HREF="#TOC1">MULTI-THREADING</A>
+<P>
+The PCRE functions can be used in multi-threading applications, with the
+proviso that the memory management functions pointed to by <B>pcre_malloc</B>
+and <B>pcre_free</B> are shared by all threads.
+</P>
+<P>
+The compiled form of a regular expression is not altered during matching, so
+the same compiled pattern can safely be used by several threads at once.
+</P>
+<LI><A NAME="SEC5" HREF="#TOC1">COMPILING A PATTERN</A>
+<P>
+The function <B>pcre_compile()</B> is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument <I>pattern</I>. A pointer to a single block of memory
+that is obtained via <B>pcre_malloc</B> is returned. This contains the
+compiled code and related data. The <B>pcre</B> type is defined for this for
+convenience, but in fact <B>pcre</B> is just a typedef for <B>void</B>, since the
+contents of the block are not externally defined. It is up to the caller to
+free the memory when it is no longer required.
+</P>
+<P>
+The size of a compiled pattern is roughly proportional to the length of the
+pattern string, except that each character class (other than those containing
+just a single character, negated or not) requires 33 bytes, and repeat
+quantifiers with a minimum greater than one or a bounded maximum cause the
+relevant portions of the compiled pattern to be replicated.
+</P>
+<P>
+The <I>options</I> argument contains independent bits that affect the
+compilation. It should be zero if no options are required. Some of the options,
+in particular, those that are compatible with Perl, can also be set and unset
+from within the pattern (see the detailed description of regular expressions
+below). For these options, the contents of the <I>options</I> argument specifies
+their initial settings at the start of compilation and execution. The
+PCRE_ANCHORED option can be set at the time of matching as well as at compile
+time.
+</P>
+<P>
+If <I>errptr</I> is NULL, <B>pcre_compile()</B> returns NULL immediately.
+Otherwise, if compilation of a pattern fails, <B>pcre_compile()</B> returns
+NULL, and sets the variable pointed to by <I>errptr</I> to point to a textual
+error message. The offset from the start of the pattern to the character where
+the error was discovered is placed in the variable pointed to by
+<I>erroffset</I>, which must not be NULL. If it is, an immediate error is given.
+</P>
+<P>
+If the final argument, <I>tableptr</I>, is NULL, PCRE uses a default set of
+character tables which are built when it is compiled, using the default C
+locale. Otherwise, <I>tableptr</I> must be the result of a call to
+<B>pcre_maketables()</B>. See the section on locale support below.
+</P>
+<P>
+The following option bits are defined in the header file:
+</P>
+<P>
+<PRE>
+ PCRE_ANCHORED
+</PRE>
+</P>
+<P>
+If this bit is set, the pattern is forced to be "anchored", that is, it is
+constrained to match only at the start of the string which is being searched
+(the "subject string"). This effect can also be achieved by appropriate
+constructs in the pattern itself, which is the only way to do it in Perl.
+</P>
+<P>
+<PRE>
+ PCRE_CASELESS
+</PRE>
+</P>
+<P>
+If this bit is set, letters in the pattern match both upper and lower case
+letters. It is equivalent to Perl's /i option.
+</P>
+<P>
+<PRE>
+ PCRE_DOLLAR_ENDONLY
+</PRE>
+</P>
+<P>
+If this bit is set, a dollar metacharacter in the pattern matches only at the
+end of the subject string. Without this option, a dollar also matches
+immediately before the final character if it is a newline (but not before any
+other newlines). The PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is
+set. There is no equivalent to this option in Perl.
+</P>
+<P>
+<PRE>
+ PCRE_DOTALL
+</PRE>
+</P>
+<P>
+If this bit is set, a dot metacharater in the pattern matches all characters,
+including newlines. Without it, newlines are excluded. This option is
+equivalent to Perl's /s option. A negative class such as [^a] always matches a
+newline character, independent of the setting of this option.
+</P>
+<P>
+<PRE>
+ PCRE_EXTENDED
+</PRE>
+</P>
+<P>
+If this bit is set, whitespace data characters in the pattern are totally
+ignored except when escaped or inside a character class, and characters between
+an unescaped # outside a character class and the next newline character,
+inclusive, are also ignored. This is equivalent to Perl's /x option, and makes
+it possible to include comments inside complicated patterns. Note, however,
+that this applies only to data characters. Whitespace characters may never
+appear within special character sequences in a pattern, for example within the
+sequence (?( which introduces a conditional subpattern.
+</P>
+<P>
+<PRE>
+ PCRE_EXTRA
+</PRE>
+</P>
+<P>
+This option was invented in order to turn on additional functionality of PCRE
+that is incompatible with Perl, but it is currently of very little use. When
+set, any backslash in a pattern that is followed by a letter that has no
+special meaning causes an error, thus reserving these combinations for future
+expansion. By default, as in Perl, a backslash followed by a letter with no
+special meaning is treated as a literal. There are at present no other features
+controlled by this option. It can also be set by a (?X) option setting within a
+pattern.
+</P>
+<P>
+<PRE>
+ PCRE_MULTILINE
+</PRE>
+</P>
+<P>
+By default, PCRE treats the subject string as consisting of a single "line" of
+characters (even if it actually contains several newlines). The "start of line"
+metacharacter (^) matches only at the start of the string, while the "end of
+line" metacharacter ($) matches only at the end of the string, or before a
+terminating newline (unless PCRE_DOLLAR_ENDONLY is set). This is the same as
+Perl.
+</P>
+<P>
+When PCRE_MULTILINE it is set, the "start of line" and "end of line" constructs
+match immediately following or immediately before any newline in the subject
+string, respectively, as well as at the very start and end. This is equivalent
+to Perl's /m option. If there are no "\n" characters in a subject string, or
+no occurrences of ^ or $ in a pattern, setting PCRE_MULTILINE has no
+effect.
+</P>
+<P>
+<PRE>
+ PCRE_UNGREEDY
+</PRE>
+</P>
+<P>
+This option inverts the "greediness" of the quantifiers so that they are not
+greedy by default, but become greedy if followed by "?". It is not compatible
+with Perl. It can also be set by a (?U) option setting within the pattern.
+</P>
+<P>
+<PRE>
+ PCRE_UTF8
+</PRE>
+</P>
+<P>
+This option causes PCRE to regard both the pattern and the subject as strings
+of UTF-8 characters instead of just byte strings. However, it is available only
+if PCRE has been built to include UTF-8 support. If not, the use of this option
+provokes an error. Support for UTF-8 is new, experimental, and incomplete.
+Details of exactly what it entails are given below.
+</P>
+<LI><A NAME="SEC6" HREF="#TOC1">STUDYING A PATTERN</A>
+<P>
+When a pattern is going to be used several times, it is worth spending more
+time analyzing it in order to speed up the time taken for matching. The
+function <B>pcre_study()</B> takes a pointer to a compiled pattern as its first
+argument, and returns a pointer to a <B>pcre_extra</B> block (another <B>void</B>
+typedef) containing additional information about the pattern; this can be
+passed to <B>pcre_exec()</B>. If no additional information is available, NULL
+is returned.
+</P>
+<P>
+The second argument contains option bits. At present, no options are defined
+for <B>pcre_study()</B>, and this argument should always be zero.
+</P>
+<P>
+The third argument for <B>pcre_study()</B> is a pointer to an error message. If
+studying succeeds (even if no data is returned), the variable it points to is
+set to NULL. Otherwise it points to a textual error message.
+</P>
+<P>
+At present, studying a pattern is useful only for non-anchored patterns that do
+not have a single fixed starting character. A bitmap of possible starting
+characters is created.
+</P>
+<LI><A NAME="SEC7" HREF="#TOC1">LOCALE SUPPORT</A>
+<P>
+PCRE handles caseless matching, and determines whether characters are letters,
+digits, or whatever, by reference to a set of tables. The library contains a
+default set of tables which is created in the default C locale when PCRE is
+compiled. This is used when the final argument of <B>pcre_compile()</B> is NULL,
+and is sufficient for many applications.
+</P>
+<P>
+An alternative set of tables can, however, be supplied. Such tables are built
+by calling the <B>pcre_maketables()</B> function, which has no arguments, in the
+relevant locale. The result can then be passed to <B>pcre_compile()</B> as often
+as necessary. For example, to build and use tables that are appropriate for the
+French locale (where accented characters with codes greater than 128 are
+treated as letters), the following code could be used:
+</P>
+<P>
+<PRE>
+ setlocale(LC_CTYPE, "fr");
+ tables = pcre_maketables();
+ re = pcre_compile(..., tables);
+</PRE>
+</P>
+<P>
+The tables are built in memory that is obtained via <B>pcre_malloc</B>. The
+pointer that is passed to <B>pcre_compile</B> is saved with the compiled
+pattern, and the same tables are used via this pointer by <B>pcre_study()</B>
+and <B>pcre_exec()</B>. Thus for any single pattern, compilation, studying and
+matching all happen in the same locale, but different patterns can be compiled
+in different locales. It is the caller's responsibility to ensure that the
+memory containing the tables remains available for as long as it is needed.
+</P>
+<LI><A NAME="SEC8" HREF="#TOC1">INFORMATION ABOUT A PATTERN</A>
+<P>
+The <B>pcre_fullinfo()</B> function returns information about a compiled
+pattern. It replaces the obsolete <B>pcre_info()</B> function, which is
+nevertheless retained for backwards compability (and is documented below).
+</P>
+<P>
+The first argument for <B>pcre_fullinfo()</B> is a pointer to the compiled
+pattern. The second argument is the result of <B>pcre_study()</B>, or NULL if
+the pattern was not studied. The third argument specifies which piece of
+information is required, while the fourth argument is a pointer to a variable
+to receive the data. The yield of the function is zero for success, or one of
+the following negative numbers:
+</P>
+<P>
+<PRE>
+ PCRE_ERROR_NULL the argument <I>code</I> was NULL
+ the argument <I>where</I> was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+ PCRE_ERROR_BADOPTION the value of <I>what</I> was invalid
+</PRE>
+</P>
+<P>
+The possible values for the third argument are defined in <B>pcre.h</B>, and are
+as follows:
+</P>
+<P>
+<PRE>
+ PCRE_INFO_OPTIONS
+</PRE>
+</P>
+<P>
+Return a copy of the options with which the pattern was compiled. The fourth
+argument should point to au <B>unsigned long int</B> variable. These option bits
+are those specified in the call to <B>pcre_compile()</B>, modified by any
+top-level option settings within the pattern itself, and with the PCRE_ANCHORED
+bit forcibly set if the form of the pattern implies that it can match only at
+the start of a subject string.
+</P>
+<P>
+<PRE>
+ PCRE_INFO_SIZE
+</PRE>
+</P>
+<P>
+Return the size of the compiled pattern, that is, the value that was passed as
+the argument to <B>pcre_malloc()</B> when PCRE was getting memory in which to
+place the compiled data. The fourth argument should point to a <B>size_t</B>
+variable.
+</P>
+<P>
+<PRE>
+ PCRE_INFO_CAPTURECOUNT
+</PRE>
+</P>
+<P>
+Return the number of capturing subpatterns in the pattern. The fourth argument
+should point to an \fbint\fR variable.
+</P>
+<P>
+<PRE>
+ PCRE_INFO_BACKREFMAX
+</PRE>
+</P>
+<P>
+Return the number of the highest back reference in the pattern. The fourth
+argument should point to an <B>int</B> variable. Zero is returned if there are
+no back references.
+</P>
+<P>
+<PRE>
+ PCRE_INFO_FIRSTCHAR
+</PRE>
+</P>
+<P>
+Return information about the first character of any matched string, for a
+non-anchored pattern. If there is a fixed first character, e.g. from a pattern
+such as (cat|cow|coyote), it is returned in the integer pointed to by
+<I>where</I>. Otherwise, if either
+</P>
+<P>
+(a) the pattern was compiled with the PCRE_MULTILINE option, and every branch
+starts with "^", or
+</P>
+<P>
+(b) every branch of the pattern starts with ".*" and PCRE_DOTALL is not set
+(if it were set, the pattern would be anchored),
+</P>
+<P>
+-1 is returned, indicating that the pattern matches only at the start of a
+subject string or after any "\n" within the string. Otherwise -2 is returned.
+For anchored patterns, -2 is returned.
+</P>
+<P>
+<PRE>
+ PCRE_INFO_FIRSTTABLE
+</PRE>
+</P>
+<P>
+If the pattern was studied, and this resulted in the construction of a 256-bit
+table indicating a fixed set of characters for the first character in any
+matching string, a pointer to the table is returned. Otherwise NULL is
+returned. The fourth argument should point to an <B>unsigned char *</B>
+variable.
+</P>
+<P>
+<PRE>
+ PCRE_INFO_LASTLITERAL
+</PRE>
+</P>
+<P>
+For a non-anchored pattern, return the value of the rightmost literal character
+which must exist in any matched string, other than at its start. The fourth
+argument should point to an <B>int</B> variable. If there is no such character,
+or if the pattern is anchored, -1 is returned. For example, for the pattern
+/a\d+z\d+/ the returned value is 'z'.
+</P>
+<P>
+The <B>pcre_info()</B> function is now obsolete because its interface is too
+restrictive to return all the available data about a compiled pattern. New
+programs should use <B>pcre_fullinfo()</B> instead. The yield of
+<B>pcre_info()</B> is the number of capturing subpatterns, or one of the
+following negative numbers:
+</P>
+<P>
+<PRE>
+ PCRE_ERROR_NULL the argument <I>code</I> was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+</PRE>
+</P>
+<P>
+If the <I>optptr</I> argument is not NULL, a copy of the options with which the
+pattern was compiled is placed in the integer it points to (see
+PCRE_INFO_OPTIONS above).
+</P>
+<P>
+If the pattern is not anchored and the <I>firstcharptr</I> argument is not NULL,
+it is used to pass back information about the first character of any matched
+string (see PCRE_INFO_FIRSTCHAR above).
+</P>
+<LI><A NAME="SEC9" HREF="#TOC1">MATCHING A PATTERN</A>
+<P>
+The function <B>pcre_exec()</B> is called to match a subject string against a
+pre-compiled pattern, which is passed in the <I>code</I> argument. If the
+pattern has been studied, the result of the study should be passed in the
+<I>extra</I> argument. Otherwise this must be NULL.
+</P>
+<P>
+The PCRE_ANCHORED option can be passed in the <I>options</I> argument, whose
+unused bits must be zero. However, if a pattern was compiled with
+PCRE_ANCHORED, or turned out to be anchored by virtue of its contents, it
+cannot be made unachored at matching time.
+</P>
+<P>
+There are also three further options that can be set only at matching time:
+</P>
+<P>
+<PRE>
+ PCRE_NOTBOL
+</PRE>
+</P>
+<P>
+The first character of the string is not the beginning of a line, so the
+circumflex metacharacter should not match before it. Setting this without
+PCRE_MULTILINE (at compile time) causes circumflex never to match.
+</P>
+<P>
+<PRE>
+ PCRE_NOTEOL
+</PRE>
+</P>
+<P>
+The end of the string is not the end of a line, so the dollar metacharacter
+should not match it nor (except in multiline mode) a newline immediately before
+it. Setting this without PCRE_MULTILINE (at compile time) causes dollar never
+to match.
+</P>
+<P>
+<PRE>
+ PCRE_NOTEMPTY
+</PRE>
+</P>
+<P>
+An empty string is not considered to be a valid match if this option is set. If
+there are alternatives in the pattern, they are tried. If all the alternatives
+match the empty string, the entire match fails. For example, if the pattern
+</P>
+<P>
+<PRE>
+ a?b?
+</PRE>
+</P>
+<P>
+is applied to a string not beginning with "a" or "b", it matches the empty
+string at the start of the subject. With PCRE_NOTEMPTY set, this match is not
+valid, so PCRE searches further into the string for occurrences of "a" or "b".
+</P>
+<P>
+Perl has no direct equivalent of PCRE_NOTEMPTY, but it does make a special case
+of a pattern match of the empty string within its <B>split()</B> function, and
+when using the /g modifier. It is possible to emulate Perl's behaviour after
+matching a null string by first trying the match again at the same offset with
+PCRE_NOTEMPTY set, and then if that fails by advancing the starting offset (see
+below) and trying an ordinary match again.
+</P>
+<P>
+The subject string is passed as a pointer in <I>subject</I>, a length in
+<I>length</I>, and a starting offset in <I>startoffset</I>. Unlike the pattern
+string, it may contain binary zero characters. When the starting offset is
+zero, the search for a match starts at the beginning of the subject, and this
+is by far the most common case.
+</P>
+<P>
+A non-zero starting offset is useful when searching for another match in the
+same subject by calling <B>pcre_exec()</B> again after a previous success.
+Setting <I>startoffset</I> differs from just passing over a shortened string and
+setting PCRE_NOTBOL in the case of a pattern that begins with any kind of
+lookbehind. For example, consider the pattern
+</P>
+<P>
+<PRE>
+ \Biss\B
+</PRE>
+</P>
+<P>
+which finds occurrences of "iss" in the middle of words. (\B matches only if
+the current position in the subject is not a word boundary.) When applied to
+the string "Mississipi" the first call to <B>pcre_exec()</B> finds the first
+occurrence. If <B>pcre_exec()</B> is called again with just the remainder of the
+subject, namely "issipi", it does not match, because \B is always false at the
+start of the subject, which is deemed to be a word boundary. However, if
+<B>pcre_exec()</B> is passed the entire string again, but with <I>startoffset</I>
+set to 4, it finds the second occurrence of "iss" because it is able to look
+behind the starting point to discover that it is preceded by a letter.
+</P>
+<P>
+If a non-zero starting offset is passed when the pattern is anchored, one
+attempt to match at the given offset is tried. This can only succeed if the
+pattern does not require the match to be at the start of the subject.
+</P>
+<P>
+In general, a pattern matches a certain portion of the subject, and in
+addition, further substrings from the subject may be picked out by parts of the
+pattern. Following the usage in Jeffrey Friedl's book, this is called
+"capturing" in what follows, and the phrase "capturing subpattern" is used for
+a fragment of a pattern that picks out a substring. PCRE supports several other
+kinds of parenthesized subpattern that do not cause substrings to be captured.
+</P>
+<P>
+Captured substrings are returned to the caller via a vector of integer offsets
+whose address is passed in <I>ovector</I>. The number of elements in the vector
+is passed in <I>ovecsize</I>. The first two-thirds of the vector is used to pass
+back captured substrings, each substring using a pair of integers. The
+remaining third of the vector is used as workspace by <B>pcre_exec()</B> while
+matching capturing subpatterns, and is not available for passing back
+information. The length passed in <I>ovecsize</I> should always be a multiple of
+three. If it is not, it is rounded down.
+</P>
+<P>
+When a match has been successful, information about captured substrings is
+returned in pairs of integers, starting at the beginning of <I>ovector</I>, and
+continuing up to two-thirds of its length at the most. The first element of a
+pair is set to the offset of the first character in a substring, and the second
+is set to the offset of the first character after the end of a substring. The
+first pair, <I>ovector[0]</I> and <I>ovector[1]</I>, identify the portion of the
+subject string matched by the entire pattern. The next pair is used for the
+first capturing subpattern, and so on. The value returned by <B>pcre_exec()</B>
+is the number of pairs that have been set. If there are no capturing
+subpatterns, the return value from a successful match is 1, indicating that
+just the first pair of offsets has been set.
+</P>
+<P>
+Some convenience functions are provided for extracting the captured substrings
+as separate strings. These are described in the following section.
+</P>
+<P>
+It is possible for an capturing subpattern number <I>n+1</I> to match some
+part of the subject when subpattern <I>n</I> has not been used at all. For
+example, if the string "abc" is matched against the pattern (a|(z))(bc)
+subpatterns 1 and 3 are matched, but 2 is not. When this happens, both offset
+values corresponding to the unused subpattern are set to -1.
+</P>
+<P>
+If a capturing subpattern is matched repeatedly, it is the last portion of the
+string that it matched that gets returned.
+</P>
+<P>
+If the vector is too small to hold all the captured substrings, it is used as
+far as possible (up to two-thirds of its length), and the function returns a
+value of zero. In particular, if the substring offsets are not of interest,
+<B>pcre_exec()</B> may be called with <I>ovector</I> passed as NULL and
+<I>ovecsize</I> as zero. However, if the pattern contains back references and
+the <I>ovector</I> isn't big enough to remember the related substrings, PCRE has
+to get additional memory for use during matching. Thus it is usually advisable
+to supply an <I>ovector</I>.
+</P>
+<P>
+Note that <B>pcre_info()</B> can be used to find out how many capturing
+subpatterns there are in a compiled pattern. The smallest size for
+<I>ovector</I> that will allow for <I>n</I> captured substrings in addition to
+the offsets of the substring matched by the whole pattern is (<I>n</I>+1)*3.
+</P>
+<P>
+If <B>pcre_exec()</B> fails, it returns a negative number. The following are

+<LI><A NAME="SEC10" HREF="#TOC1">EXTRACTING CAPTURED SUBSTRINGS</A>
+<P>
+Captured substrings can be accessed directly by using the offsets returned by

+<B>pcre_copy_substring()</B>, <B>pcre_get_substring()</B>, and
+<B>pcre_get_substring_list()</B> are provided for extracting captured substrings
+as new, separate, zero-terminated strings. A substring that contains a binary
+zero is correctly extracted and has a further zero added on the end, but the
+result does not, of course, function as a C string.
+</P>
+<P>
+The first three arguments are the same for all three functions: <I>subject</I>
+is the subject string which has just been successfully matched, <I>ovector</I>
+is a pointer to the vector of integer offsets that was passed to
+<B>pcre_exec()</B>, and <I>stringcount</I> is the number of substrings that
+were captured by the match, including the substring that matched the entire
+regular expression. This is the value returned by <B>pcre_exec</B> if it
+is greater than zero. If <B>pcre_exec()</B> returned zero, indicating that it
+ran out of space in <I>ovector</I>, the value passed as <I>stringcount</I> should

+<LI><A NAME="SEC11" HREF="#TOC1">LIMITATIONS</A>
+<P>
+There are some size limitations in PCRE but it is hoped that they will never in
+practice be relevant.
+The maximum length of a compiled pattern is 65539 (sic) bytes.
+All values in repeating quantifiers must be less than 65536.
+The maximum number of capturing subpatterns is 99.
+The maximum number of all parenthesized subpatterns, including capturing
+subpatterns, assertions, and other types of subpattern, is 200.
+</P>
+<P>
+The maximum length of a subject string is the largest positive number that an
+integer variable can hold. However, PCRE uses recursion to handle subpatterns
+and indefinite repetition. This means that the available stack space may limit
+the size of a subject string that can be processed by certain patterns.
+</P>
+<LI><A NAME="SEC12" HREF="#TOC1">DIFFERENCES FROM PERL</A>
+<P>
+The differences described here are with respect to Perl 5.005.
+</P>
+<P>
+1. By default, a whitespace character is any character that the C library
+function <B>isspace()</B> recognizes, though it is possible to compile PCRE with
+alternative character type tables. Normally <B>isspace()</B> matches space,
+formfeed, newline, carriage return, horizontal tab, and vertical tab. Perl 5
+no longer includes vertical tab in its set of whitespace characters. The \v
+escape that was in the Perl documentation for a long time was never in fact
+recognized. However, the character itself was treated as whitespace at least
+up to 5.002. In 5.004 and 5.005 it does not match \s.
+</P>
+<P>
+2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl permits
+them, but they do not mean what you might think. For example, (?!a){3} does
+not assert that the next three characters are not "a". It just asserts that the
+next character is not "a" three times.
+</P>
+<P>
+3. Capturing subpatterns that occur inside negative lookahead assertions are
+counted, but their entries in the offsets vector are never set. Perl sets its
+numerical variables from any such patterns that are matched before the
+assertion fails to match something (thereby succeeding), but only if the
+negative lookahead assertion contains just one branch.
+</P>
+<P>
+4. Though binary zero characters are supported in the subject string, they are
+not allowed in a pattern string because it is passed as a normal C string,
+terminated by zero. The escape sequence "\0" can be used in the pattern to
+represent a binary zero.
+</P>
+<P>
+5. The following Perl escape sequences are not supported: \l, \u, \L, \U,
+\E, \Q. In fact these are implemented by Perl's general string-handling and
+are not part of its pattern matching engine.
+</P>
+<P>
+6. The Perl \G assertion is not supported as it is not relevant to single
+pattern matches.
+</P>
+<P>
+7. Fairly obviously, PCRE does not support the (?{code}) and (?p{code})
+constructions. However, there is some experimental support for recursive
+patterns using the non-Perl item (?R).
+</P>
+<P>
+8. There are at the time of writing some oddities in Perl 5.005_02 concerned
+with the settings of captured strings when part of a pattern is repeated. For
+example, matching "aba" against the pattern /^(a(b)?)+$/ sets $2 to the value
+"b", but matching "aabbaa" against /^(aa(bb)?)+$/ leaves $2 unset. However, if
+the pattern is changed to /^(aa(b(b))?)+$/ then $2 (and $3) are set.
+</P>
+<P>
+In Perl 5.004 $2 is set in both cases, and that is also true of PCRE. If in the
+future Perl changes to a consistent state that is different, PCRE may change to
+follow.
+</P>
+<P>
+9. Another as yet unresolved discrepancy is that in Perl 5.005_02 the pattern
+/^(a)?(?(1)a|b)+$/ matches the string "a", whereas in PCRE it does not.
+However, in both Perl and PCRE /^(a)?a/ matched against "a" leaves $1 unset.
+</P>
+<P>
+10. PCRE provides some extensions to the Perl regular expression facilities:
+</P>
+<P>
+(a) Although lookbehind assertions must match fixed length strings, each
+alternative branch of a lookbehind assertion can match a different length of
+string. Perl 5.005 requires them all to have the same length.
+</P>
+<P>
+(b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not set, the $ meta-
+character matches only at the very end of the string.
+</P>
+<P>
+(c) If PCRE_EXTRA is set, a backslash followed by a letter with no special
+meaning is faulted.
+</P>
+<P>
+(d) If PCRE_UNGREEDY is set, the greediness of the repetition quantifiers is
+inverted, that is, by default they are not greedy, but if followed by a
+question mark they are.
+</P>
+<P>
+(e) PCRE_ANCHORED can be used to force a pattern to be tried only at the start
+of the subject.
+</P>
+<P>
+(f) The PCRE_NOTBOL, PCRE_NOTEOL, and PCRE_NOTEMPTY options for
+<B>pcre_exec()</B> have no Perl equivalents.
+</P>
+<P>
+(g) The (?R) construct allows for recursive pattern matching (Perl 5.6 can do
+this using the (?p{code}) construct, which PCRE cannot of course support.)
+</P>
+<LI><A NAME="SEC13" HREF="#TOC1">REGULAR EXPRESSION DETAILS</A>
+<P>
+The syntax and semantics of the regular expressions supported by PCRE are
+described below. Regular expressions are also described in the Perl
+documentation and in a number of other books, some of which have copious
+examples. Jeffrey Friedl's "Mastering Regular Expressions", published by
+O'Reilly (ISBN 1-56592-257), covers them in great detail.
+</P>
+<P>
+The description here is intended as reference documentation. The basic
+operation of PCRE is on strings of bytes. However, there is the beginnings of
+some support for UTF-8 character strings. To use this support you must
+configure PCRE to include it, and then call <B>pcre_compile()</B> with the
+PCRE_UTF8 option. How this affects the pattern matching is described in the
+final section of this document.
+</P>
+<P>
+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+</P>
+<P>
+<PRE>
+ The quick brown fox
+</PRE>
+</P>
+<P>
+matches a portion of a subject string that is identical to itself. The power of
+regular expressions comes from the ability to include alternatives and
+repetitions in the pattern. These are encoded in the pattern by the use of
+<I>meta-characters</I>, which do not stand for themselves but instead are
+interpreted in some special way.
+</P>
+<P>
+There are two different sets of meta-characters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized in square brackets. Outside square brackets, the meta-characters are
+as follows:
+</P>
+<P>
+<PRE>
+ \ general escape character with several uses
+ ^ assert start of subject (or line, in multiline mode)
+ $ assert end of subject (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ { start min/max quantifier
+</PRE>
+</P>
+<P>
+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only meta-characters are:
+</P>
+<P>
+<PRE>
+ \ general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+ ] terminates the character class
+</PRE>
+</P>
+<P>
+The following sections describe the use of each of the meta-characters.
+</P>
+<LI><A NAME="SEC14" HREF="#TOC1">BACKSLASH</A>
+<P>
+The backslash character has several uses. Firstly, if it is followed by a
+non-alphameric character, it takes away any special meaning that character may
+have. This use of backslash as an escape character applies both inside and
+outside character classes.
+</P>
+<P>
+For example, if you want to match a "*" character, you write "\*" in the
+pattern. This applies whether or not the following character would otherwise be
+interpreted as a meta-character, so it is always safe to precede a
+non-alphameric with "\" to specify that it stands for itself. In particular,
+if you want to match a backslash, you write "\\".
+</P>
+<P>
+If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the
+pattern (other than in a character class) and characters between a "#" outside
+a character class and the next newline character are ignored. An escaping
+backslash can be used to include a whitespace or "#" character as part of the
+pattern.
+</P>
+<P>
+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters, apart from the binary zero that terminates a pattern,
+but when a pattern is being prepared by text editing, it is usually easier to
+use one of the following escape sequences than the binary character it
+represents:
+</P>
+<P>
+<PRE>
+ \a alarm, that is, the BEL character (hex 07)
+ \cx "control-x", where x is any character
+ \e escape (hex 1B)
+ \f formfeed (hex 0C)
+ \n newline (hex 0A)
+ \r carriage return (hex 0D)
+ \t tab (hex 09)
+ \xhh character with hex code hh
+ \ddd character with octal code ddd, or backreference
+</PRE>
+</P>
+<P>
+The precise effect of "\cx" is as follows: if "x" is a lower case letter, it
+is converted to upper case. Then bit 6 of the character (hex 40) is inverted.
+Thus "\cz" becomes hex 1A, but "\c{" becomes hex 3B, while "\c;" becomes hex
+7B.
+</P>
+<P>
+After "\x", up to two hexadecimal digits are read (letters can be in upper or
+lower case).
+</P>
+<P>
+After "\0" up to two further octal digits are read. In both cases, if there
+are fewer than two digits, just those that are present are used. Thus the
+sequence "\0\x\07" specifies two binary zeros followed by a BEL character.
+Make sure you supply two digits after the initial zero if the character that
+follows is itself an octal digit.
+</P>
+<P>
+The handling of a backslash followed by a digit other than 0 is complicated.
+Outside a character class, PCRE reads it and any following digits as a decimal
+number. If the number is less than 10, or if there have been at least that many
+previous capturing left parentheses in the expression, the entire sequence is
+taken as a <I>back reference</I>. A description of how this works is given
+later, following the discussion of parenthesized subpatterns.
+</P>
+<P>
+Inside a character class, or if the decimal number is greater than 9 and there
+have not been that many capturing subpatterns, PCRE re-reads up to three octal
+digits following the backslash, and generates a single byte from the least
+significant 8 bits of the value. Any subsequent digits stand for themselves.
+For example:
+</P>
+<P>
+<PRE>
+ \040 is another way of writing a space
+ \40 is the same, provided there are fewer than 40
+ previous capturing subpatterns
+ \7 is always a back reference
+ \11 might be a back reference, or another way of
+ writing a tab
+ \011 is always a tab
+ \0113 is a tab followed by the character "3"
+ \113 is the character with octal code 113 (since there
+ can be no more than 99 back references)
+ \377 is a byte consisting entirely of 1 bits
+ \81 is either a back reference, or a binary zero
+ followed by the two characters "8" and "1"
+</PRE>
+</P>
+<P>
+Note that octal values of 100 or greater must not be introduced by a leading
+zero, because no more than three octal digits are ever read.
+</P>
+<P>
+All the sequences that define a single byte value can be used both inside and
+outside character classes. In addition, inside a character class, the sequence
+"\b" is interpreted as the backspace character (hex 08). Outside a character
+class it has a different meaning (see below).
+</P>
+<P>
+The third use of backslash is for specifying generic character types:
+</P>
+<P>
+<PRE>
+ \d any decimal digit
+ \D any character that is not a decimal digit
+ \s any whitespace character
+ \S any character that is not a whitespace character
+ \w any "word" character
+ \W any "non-word" character
+</PRE>
+</P>
+<P>
+Each pair of escape sequences partitions the complete set of characters into
+two disjoint sets. Any given character matches one, and only one, of each pair.
+</P>
+<P>
+A "word" character is any letter or digit or the underscore character, that is,
+any character which can be part of a Perl "word". The definition of letters and
+digits is controlled by PCRE's character tables, and may vary if locale-
+specific matching is taking place (see "Locale support" above). For example, in
+the "fr" (French) locale, some character codes greater than 128 are used for
+accented letters, and these are matched by \w.
+</P>
+<P>
+These character type sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, since
+there is no character to match.
+</P>
+<P>
+The fourth use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+subpatterns for more complicated assertions is described below. The backslashed
+assertions are
+</P>
+<P>
+<PRE>
+ \b word boundary
+ \B not a word boundary
+ \A start of subject (independent of multiline mode)
+ \Z end of subject or newline at end (independent of multiline mode)
+ \z end of subject (independent of multiline mode)
+</PRE>
+</P>
+<P>
+These assertions may not appear in character classes (but note that "\b" has a
+different meaning, namely the backspace character, inside a character class).
+</P>
+<P>
+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \w or \W (i.e. one matches
+\w and the other matches \W), or the start or end of the string if the
+first or last character matches \w, respectively.
+</P>
+<P>
+The \A, \Z, and \z assertions differ from the traditional circumflex and
+dollar (described below) in that they only ever match at the very start and end
+of the subject string, whatever options are set. They are not affected by the
+PCRE_NOTBOL or PCRE_NOTEOL options. If the <I>startoffset</I> argument of
+<B>pcre_exec()</B> is non-zero, \A can never match. The difference between \Z
+and \z is that \Z matches before a newline that is the last character of the
+string as well as at the end of the string, whereas \z matches only at the
+end.
+</P>
+<LI><A NAME="SEC15" HREF="#TOC1">CIRCUMFLEX AND DOLLAR</A>
+<P>
+Outside a character class, in the default matching mode, the circumflex
+character is an assertion which is true only if the current matching point is
+at the start of the subject string. If the <I>startoffset</I> argument of
+<B>pcre_exec()</B> is non-zero, circumflex can never match. Inside a character
+class, circumflex has an entirely different meaning (see below).
+</P>
+<P>
+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+</P>
+<P>
+A dollar character is an assertion which is true only if the current matching
+point is at the end of the subject string, or immediately before a newline
+character that is the last character in the string (by default). Dollar need
+not be the last character of the pattern if a number of alternatives are
+involved, but it should be the last item in any branch in which it appears.
+Dollar has no special meaning in a character class.
+</P>
+<P>
+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE_DOLLAR_ENDONLY option at compile or matching
+time. This does not affect the \Z assertion.
+</P>
+<P>
+The meanings of the circumflex and dollar characters are changed if the
+PCRE_MULTILINE option is set. When this is the case, they match immediately
+after and immediately before an internal "\n" character, respectively, in
+addition to matching at the start and end of the subject string. For example,
+the pattern /^abc$/ matches the subject string "def\nabc" in multiline mode,
+but not otherwise. Consequently, patterns that are anchored in single line mode
+because all branches start with "^" are not anchored in multiline mode, and a
+match for circumflex is possible when the <I>startoffset</I> argument of
+<B>pcre_exec()</B> is non-zero. The PCRE_DOLLAR_ENDONLY option is ignored if
+PCRE_MULTILINE is set.
+</P>
+<P>
+Note that the sequences \A, \Z, and \z can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\A is it always anchored, whether PCRE_MULTILINE is set or not.
+</P>
+<LI><A NAME="SEC16" HREF="#TOC1">FULL STOP (PERIOD, DOT)</A>
+<P>
+Outside a character class, a dot in the pattern matches any one character in
+the subject, including a non-printing character, but not (by default) newline.
+If the PCRE_DOTALL option is set, dots match newlines as well. The handling of
+dot is entirely independent of the handling of circumflex and dollar, the only
+relationship being that they both involve newline characters. Dot has no
+special meaning in a character class.
+</P>
+<LI><A NAME="SEC17" HREF="#TOC1">SQUARE BRACKETS</A>
+<P>
+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special. If a
+closing square bracket is required as a member of the class, it should be the
+first data character in the class (after an initial circumflex, if present) or
+escaped with a backslash.
+</P>
+<P>
+A character class matches a single character in the subject; the character must
+be in the set of characters defined by the class, unless the first character in
+the class is a circumflex, in which case the subject character must not be in
+the set defined by the class. If a circumflex is actually required as a member
+of the class, ensure it is not the first character, or escape it with a
+backslash.
+</P>
+<P>
+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters which
+are in the class by enumerating those that are not. It is not an assertion: it
+still consumes a character from the subject string, and fails if the current
+pointer is at the end of the string.
+</P>
+<P>
+When caseless matching is set, any letters in a class represent both their
+upper case and lower case versions, so for example, a caseless [aeiou] matches
+"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
+caseful version would.
+</P>
+<P>
+The newline character is never treated in any special way in character classes,
+whatever the setting of the PCRE_DOTALL or PCRE_MULTILINE options is. A class
+such as [^a] will always match a newline.
+</P>
+<P>
+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class.
+</P>
+<P>
+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\]46] is interpreted as a single class containing a
+range followed by two separate characters. The octal or hexadecimal
+representation of "]" can also be used to end a range.
+</P>
+<P>
+Ranges operate in ASCII collating sequence. They can also be used for
+characters specified numerically, for example [\000-\037]. If a range that
+includes letters is used when caseless matching is set, it matches the letters
+in either case. For example, [W-c] is equivalent to [][\^_`wxyzabc], matched
+caselessly, and if character tables for the "fr" locale are in use,
+[\xc8-\xcb] matches accented E characters in both cases.
+</P>
+<P>
+The character types \d, \D, \s, \S, \w, and \W may also appear in a
+character class, and add the characters that they match to the class. For
+example, [\dABCDEF] matches any hexadecimal digit. A circumflex can
+conveniently be used with the upper case character types to specify a more
+restricted set of characters than the matching lower case type. For example,
+the class [^\W_] matches any letter or digit, but not underscore.
+</P>
+<P>
+All non-alphameric characters other than \, -, ^ (at the start) and the
+terminating ] are non-special in character classes, but it does no harm if they
+are escaped.
+</P>
+<LI><A NAME="SEC18" HREF="#TOC1">POSIX CHARACTER CLASSES</A>
+<P>
+Perl 5.6 (not yet released at the time of writing) is going to support the
+POSIX notation for character classes, which uses names enclosed by [: and :]
+within the enclosing square brackets. PCRE supports this notation. For example,
+</P>
+<P>
+<PRE>
+ [01[:alpha:]%]
+</PRE>
+</P>
+<P>
+matches "0", "1", any alphabetic character, or "%". The supported class names
+are
+</P>
+<P>
+<PRE>
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ cntrl control characters
+ digit decimal digits (same as \d)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits
+ space white space (same as \s)
+ upper upper case letters
+ word "word" characters (same as \w)
+ xdigit hexadecimal digits
+</PRE>
+</P>
+<P>
+The names "ascii" and "word" are Perl extensions. Another Perl extension is
+negation, which is indicated by a ^ character after the colon. For example,
+</P>
+<P>
+<PRE>
+ [12[:^digit:]]
+</PRE>
+</P>
+<P>
+matches "1", "2", or any non-digit. PCRE (and Perl) also recogize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+</P>
+<LI><A NAME="SEC19" HREF="#TOC1">VERTICAL BAR</A>
+<P>
+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+</P>
+<P>
+<PRE>
+ gilbert|sullivan
+</PRE>
+</P>
+<P>
+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string).
+The matching process tries each alternative in turn, from left to right,
+and the first one that succeeds is used. If the alternatives are within a
+subpattern (defined below), "succeeds" means matching the rest of the main
+pattern as well as the alternative in the subpattern.
+</P>
+<LI><A NAME="SEC20" HREF="#TOC1">INTERNAL OPTION SETTING</A>
+<P>
+The settings of PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and PCRE_EXTENDED
+can be changed from within the pattern by a sequence of Perl option letters
+enclosed between "(?" and ")". The option letters are
+</P>
+<P>
+<PRE>
+ i for PCRE_CASELESS
+ m for PCRE_MULTILINE
+ s for PCRE_DOTALL
+ x for PCRE_EXTENDED
+</PRE>
+</P>
+<P>
+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the letter with a hyphen, and a combined
+setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and
+PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also
+permitted. If a letter appears both before and after the hyphen, the option is
+unset.
+</P>
+<P>
+The scope of these option changes depends on where in the pattern the setting
+occurs. For settings that are outside any subpattern (defined below), the
+effect is the same as if the options were set or unset at the start of
+matching. The following patterns all behave in exactly the same way:
+</P>
+<P>
+<PRE>
+ (?i)abc
+ a(?i)bc
+ ab(?i)c
+ abc(?i)
+</PRE>
+</P>
+<P>
+which in turn is the same as compiling the pattern abc with PCRE_CASELESS set.
+In other words, such "top level" settings apply to the whole pattern (unless
+there are other changes inside subpatterns). If there is more than one setting
+of the same option at top level, the rightmost setting is used.
+</P>
+<P>
+If an option change occurs inside a subpattern, the effect is different. This
+is a change of behaviour in Perl 5.005. An option change inside a subpattern
+affects only that part of the subpattern that follows it, so
+</P>
+<P>
+<PRE>
+ (a(?i)b)c
+</PRE>
+</P>
+<P>
+matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used).
+By this means, options can be made to have different settings in different
+parts of the pattern. Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern. For example,
+</P>
+<P>
+<PRE>
+ (a(?i)b|c)
+</PRE>
+</P>
+<P>
+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+</P>
+<P>
+The PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA can be changed in the
+same way as the Perl-compatible options by using the characters U and X
+respectively. The (?X) flag setting is special in that it must always occur
+earlier in the pattern than any of the additional features it turns on, even
+when it is at top level. It is best put at the start.
+</P>
+<LI><A NAME="SEC21" HREF="#TOC1">SUBPATTERNS</A>
+<P>
+Subpatterns are delimited by parentheses (round brackets), which can be nested.
+Marking part of a pattern as a subpattern does two things:
+</P>
+<P>
+1. It localizes a set of alternatives. For example, the pattern
+</P>
+<P>
+<PRE>
+ cat(aract|erpillar|)
+</PRE>
+</P>
+<P>
+matches one of the words "cat", "cataract", or "caterpillar". Without the
+parentheses, it would match "cataract", "erpillar" or the empty string.
+</P>
+<P>
+2. It sets up the subpattern as a capturing subpattern (as defined above).
+When the whole pattern matches, that portion of the subject string that matched
+the subpattern is passed back to the caller via the <I>ovector</I> argument of
+<B>pcre_exec()</B>. Opening parentheses are counted from left to right (starting
+from 1) to obtain the numbers of the capturing subpatterns.
+</P>
+<P>
+For example, if the string "the red king" is matched against the pattern
+</P>
+<P>
+<PRE>
+ the ((red|white) (king|queen))
+</PRE>
+</P>
+<P>
+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3.
+</P>
+<P>
+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when a grouping subpattern is required without a
+capturing requirement. If an opening parenthesis is followed by "?:", the
+subpattern does not do any capturing, and is not counted when computing the
+number of any subsequent capturing subpatterns. For example, if the string "the
+white queen" is matched against the pattern
+</P>
+<P>
+<PRE>
+ the ((?:red|white) (king|queen))
+</PRE>
+</P>
+<P>
+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of captured substrings is 99, and the maximum number of
+all subpatterns, both capturing and non-capturing, is 200.
+</P>
+<P>
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern, the option letters may appear between the "?" and
+the ":". Thus the two patterns
+</P>
+<P>
+<PRE>
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+</PRE>
+</P>
+<P>
+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the subpattern
+is reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+</P>
+<LI><A NAME="SEC22" HREF="#TOC1">REPETITION</A>
+<P>
+Repetition is specified by quantifiers, which can follow any of the following
+items:
+</P>
+<P>
+<PRE>
+ a single character, possibly escaped
+ the . metacharacter
+ a character class
+ a back reference (see next section)
+ a parenthesized subpattern (unless it is an assertion - see below)
+</PRE>
+</P>
+<P>
+The general repetition quantifier specifies a minimum and maximum number of
+permitted matches, by giving the two numbers in curly brackets (braces),
+separated by a comma. The numbers must be less than 65536, and the first must
+be less than or equal to the second. For example:
+</P>
+<P>
+<PRE>
+ z{2,4}
+</PRE>
+</P>
+<P>
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+</P>
+<P>
+<PRE>
+ [aeiou]{3,}
+</PRE>
+</P>
+<P>
+matches at least 3 successive vowels, but may match many more, while
+</P>
+<P>
+<PRE>
+ \d{8}
+</PRE>
+</P>
+<P>
+matches exactly 8 digits. An opening curly bracket that appears in a position
+where a quantifier is not allowed, or one that does not match the syntax of a
+quantifier, is taken as a literal character. For example, {,6} is not a
+quantifier, but a literal string of four characters.
+</P>
+<P>
+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present.
+</P>
+<P>
+For convenience (and historical compatibility) the three most common
+quantifiers have single-character abbreviations:
+</P>
+<P>
+<PRE>
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+</PRE>
+</P>
+<P>
+It is possible to construct infinite loops by following a subpattern that can
+match no characters with a quantifier that has no upper limit, for example:
+</P>
+<P>
+<PRE>
+ (a?)*
+</PRE>
+</P>
+<P>
+Earlier versions of Perl and PCRE used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but if any repetition of the subpattern does in fact
+match no characters, the loop is forcibly broken.
+</P>
+<P>
+By default, the quantifiers are "greedy", that is, they match as much as
+possible (up to the maximum number of permitted times), without causing the
+rest of the pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between the
+sequences /* and */ and within the sequence, individual * and / characters may
+appear. An attempt to match C comments by applying the pattern
+</P>
+<P>
+<PRE>
+ /\*.*\*/
+</PRE>
+</P>
+<P>
+to the string
+</P>
+<P>
+<PRE>
+ /* first command */ not comment /* second comment */
+</PRE>
+</P>
+<P>
+fails, because it matches the entire string owing to the greediness of the .*
+item.
+</P>
+<P>
+However, if a quantifier is followed by a question mark, it ceases to be
+greedy, and instead matches the minimum number of times possible, so the
+pattern
+</P>
+<P>
+<PRE>
+ /\*.*?\*/
+</PRE>
+</P>
+<P>
+does the right thing with the C comments. The meaning of the various
+quantifiers is not otherwise changed, just the preferred number of matches.
+Do not confuse this use of question mark with its use as a quantifier in its
+own right. Because it has two uses, it can sometimes appear doubled, as in
+</P>
+<P>
+<PRE>
+ \d??\d
+</PRE>
+</P>
+<P>
+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+</P>
+<P>
+If the PCRE_UNGREEDY option is set (an option which is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+</P>
+<P>
+When a parenthesized subpattern is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more store is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+</P>
+<P>
+If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the . to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE treats such a pattern as
+though it were preceded by \A. In cases where it is known that the subject
+string contains no newlines, it is worth setting PCRE_DOTALL when the pattern
+begins with .* in order to obtain this optimization, or alternatively using ^
+to indicate anchoring explicitly.
+</P>
+<P>
+When a capturing subpattern is repeated, the value captured is the substring
+that matched the final iteration. For example, after
+</P>
+<P>
+<PRE>
+ (tweedle[dume]{3}\s*)+
+</PRE>
+</P>
+<P>
+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capturing subpatterns, the
+corresponding captured values may have been set in previous iterations. For
+example, after
+</P>
+<P>
+<PRE>
+ /(a|(b))+/
+</PRE>
+</P>
+<P>
+matches "aba" the value of the second captured substring is "b".
+</P>
+<LI><A NAME="SEC23" HREF="#TOC1">BACK REFERENCES</A>
+<P>
+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a back reference to a capturing subpattern earlier
+(i.e. to its left) in the pattern, provided there have been that many previous
+capturing left parentheses.
+</P>
+<P>
+However, if the decimal number following the backslash is less than 10, it is
+always taken as a back reference, and causes an error only if there are not
+that many capturing left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of the reference for
+numbers less than 10. See the section entitled "Backslash" above for further
+details of the handling of digits following a backslash.
+</P>
+<P>
+A back reference matches whatever actually matched the capturing subpattern in
+the current subject string, rather than anything matching the subpattern
+itself. So the pattern
+</P>
+<P>
+<PRE>
+ (sens|respons)e and \1ibility
+</PRE>
+</P>
+<P>
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+back reference, the case of letters is relevant. For example,
+</P>
+<P>
+<PRE>
+ ((?i)rah)\s+\1
+</PRE>
+</P>
+<P>
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capturing subpattern is matched caselessly.
+</P>
+<P>
+There may be more than one back reference to the same subpattern. If a
+subpattern has not actually been used in a particular match, any back
+references to it always fail. For example, the pattern
+</P>
+<P>
+<PRE>
+ (a|(bc))\2
+</PRE>
+</P>
+<P>
+always fails if it starts to match "a" rather than "bc". Because there may be
+up to 99 back references, all digits following the backslash are taken
+as part of a potential back reference number. If the pattern continues with a
+digit character, some delimiter must be used to terminate the back reference.
+If the PCRE_EXTENDED option is set, this can be whitespace. Otherwise an empty
+comment can be used.
+</P>
+<P>
+A back reference that occurs inside the parentheses to which it refers fails
+when the subpattern is first used, so, for example, (a\1) never matches.
+However, such references can be useful inside repeated subpatterns. For
+example, the pattern
+</P>
+<P>
+<PRE>
+ (a|b\1)+
+</PRE>
+</P>
+<P>
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the subpattern, the back reference matches the character string corresponding
+to the previous iteration. In order for this to work, the pattern must be such
+that the first iteration does not need to match the back reference. This can be
+done using alternation, as in the example above, or by a quantifier with a
+minimum of zero.
+</P>
+<LI><A NAME="SEC24" HREF="#TOC1">ASSERTIONS</A>
+<P>
+An assertion is a test on the characters following or preceding the current
+matching point that does not actually consume any characters. The simple
+assertions coded as \b, \B, \A, \Z, \z, ^ and $ are described above. More
+complicated assertions are coded as subpatterns. There are two kinds: those
+that look ahead of the current position in the subject string, and those that
+look behind it.
+</P>
+<P>
+An assertion subpattern is matched in the normal way, except that it does not
+cause the current matching position to be changed. Lookahead assertions start
+with (?= for positive assertions and (?! for negative assertions. For example,
+</P>
+<P>
+<PRE>
+ \w+(?=;)
+</PRE>
+</P>
+<P>
+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+</P>
+<P>
+<PRE>
+ foo(?!bar)
+</PRE>
+</P>
+<P>
+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+</P>
+<P>
+<PRE>
+ (?!foo)bar
+</PRE>
+</P>
+<P>
+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve this effect.
+</P>
+<P>
+Lookbehind assertions start with (?<= for positive assertions and (?<! for
+negative assertions. For example,
+</P>
+<P>
+<PRE>
+ (?<!foo)bar
+</PRE>
+</P>
+<P>
+does find an occurrence of "bar" that is not preceded by "foo". The contents of
+a lookbehind assertion are restricted such that all the strings it matches must
+have a fixed length. However, if there are several alternatives, they do not
+all have to have the same fixed length. Thus
+</P>
+<P>
+<PRE>
+ (?<=bullock|donkey)
+</PRE>
+</P>
+<P>
+is permitted, but
+</P>
+<P>
+<PRE>
+ (?<!dogs?|cats?)
+</PRE>
+</P>
+<P>
+causes an error at compile time. Branches that match different length strings
+are permitted only at the top level of a lookbehind assertion. This is an
+extension compared with Perl 5.005, which requires all branches to match the
+same length of string. An assertion such as
+</P>
+<P>
+<PRE>
+ (?<=ab(c|de))
+</PRE>
+</P>
+<P>
+is not permitted, because its single top-level branch can match two different
+lengths, but it is acceptable if rewritten to use two top-level branches:
+</P>
+<P>
+<PRE>
+ (?<=abc|abde)
+</PRE>
+</P>
+<P>
+The implementation of lookbehind assertions is, for each alternative, to
+temporarily move the current position back by the fixed width and then try to
+match. If there are insufficient characters before the current position, the
+match is deemed to fail. Lookbehinds in conjunction with once-only subpatterns
+can be particularly useful for matching at the ends of strings; an example is
+given at the end of the section on once-only subpatterns.
+</P>
+<P>
+Several assertions (of any sort) may occur in succession. For example,
+</P>
+<P>
+<PRE>
+ (?<=\d{3})(?<!999)foo
+</PRE>
+</P>
+<P>
+matches "foo" preceded by three digits that are not "999". Notice that each of
+the assertions is applied independently at the same point in the subject
+string. First there is a check that the previous three characters are all
+digits, and then there is a check that the same three characters are not "999".
+This pattern does <I>not</I> match "foo" preceded by six characters, the first
+of which are digits and the last three of which are not "999". For example, it
+doesn't match "123abcfoo". A pattern to do that is
+</P>
+<P>
+<PRE>
+ (?<=\d{3}...)(?<!999)foo
+</PRE>
+</P>
+<P>
+This time the first assertion looks at the preceding six characters, checking
+that the first three are digits, and then the second assertion checks that the
+preceding three characters are not "999".
+</P>
+<P>
+Assertions can be nested in any combination. For example,
+</P>
+<P>
+<PRE>
+ (?<=(?<!foo)bar)baz
+</PRE>
+</P>
+<P>
+matches an occurrence of "baz" that is preceded by "bar" which in turn is not
+preceded by "foo", while
+</P>
+<P>
+<PRE>
+ (?<=\d{3}(?!999)...)foo
+</PRE>
+</P>
+<P>
+is another pattern which matches "foo" preceded by three digits and any three
+characters that are not "999".
+</P>
+<P>
+Assertion subpatterns are not capturing subpatterns, and may not be repeated,
+because it makes no sense to assert the same thing several times. If any kind
+of assertion contains capturing subpatterns within it, these are counted for
+the purposes of numbering the capturing subpatterns in the whole pattern.
+However, substring capturing is carried out only for positive assertions,
+because it does not make sense for negative assertions.
+</P>
+<P>
+Assertions count towards the maximum of 200 parenthesized subpatterns.
+</P>
+<LI><A NAME="SEC25" HREF="#TOC1">ONCE-ONLY SUBPATTERNS</A>
+<P>
+With both maximizing and minimizing repetition, failure of what follows
+normally causes the repeated item to be re-evaluated to see if a different
+number of repeats allows the rest of the pattern to match. Sometimes it is
+useful to prevent this, either to change the nature of the match, or to cause
+it fail earlier than it otherwise might, when the author of the pattern knows
+there is no point in carrying on.
+</P>
+<P>
+Consider, for example, the pattern \d+foo when applied to the subject line
+</P>
+<P>
+<PRE>
+ 123456bar
+</PRE>
+</P>
+<P>
+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \d+
+item, and then with 4, and so on, before ultimately failing. Once-only
+subpatterns provide the means for specifying that once a portion of the pattern
+has matched, it is not to be re-evaluated in this way, so the matcher would
+give up immediately on failing to match "foo" the first time. The notation is
+another kind of special parenthesis, starting with (?> as in this example:
+</P>
+<P>
+<PRE>
+ (?>\d+)bar
+</PRE>
+</P>
+<P>
+This kind of parenthesis "locks up" the part of the pattern it contains once
+it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+</P>
+<P>
+An alternative description is that a subpattern of this type matches the string
+of characters that an identical standalone pattern would match, if anchored at
+the current point in the subject string.
+</P>
+<P>
+Once-only subpatterns are not capturing subpatterns. Simple cases such as the
+above example can be thought of as a maximizing repeat that must swallow
+everything it can. So, while both \d+ and \d+? are prepared to adjust the
+number of digits they match in order to make the rest of the pattern match,
+(?>\d+) can only match an entire sequence of digits.
+</P>
+<P>
+This construction can of course contain arbitrarily complicated subpatterns,
+and it can be nested.
+</P>
+<P>
+Once-only subpatterns can be used in conjunction with lookbehind assertions to
+specify efficient matching at the end of the subject string. Consider a simple
+pattern such as
+</P>
+<P>
+<PRE>
+ abcd$
+</PRE>
+</P>
+<P>
+when applied to a long string which does not match. Because matching proceeds
+from left to right, PCRE will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+</P>
+<P>
+<PRE>
+ ^.*abcd$
+</PRE>
+</P>
+<P>
+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+</P>
+<P>
+<PRE>
+ ^(?>.*)(?<=abcd)
+</PRE>
+</P>
+<P>
+there can be no backtracking for the .* item; it can match only the entire
+string. The subsequent lookbehind assertion does a single test on the last four
+characters. If it fails, the match fails immediately. For long strings, this
+approach makes a significant difference to the processing time.
+</P>
+<P>
+When a pattern contains an unlimited repeat inside a subpattern that can itself
+be repeated an unlimited number of times, the use of a once-only subpattern is
+the only way to avoid some failing matches taking a very long time indeed.
+The pattern
+</P>
+<P>
+<PRE>
+ (\D+|<\d+>)*[!?]
+</PRE>
+</P>
+<P>
+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+</P>
+<P>
+<PRE>
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+</PRE>
+</P>
+<P>
+it takes a long time before reporting failure. This is because the string can
+be divided between the two repeats in a large number of ways, and all have to
+be tried. (The example used [!?] rather than a single character at the end,
+because both PCRE and Perl have an optimization that allows for fast failure
+when a single character is used. They remember the last single character that
+is required for a match, and fail early if it is not present in the string.)
+If the pattern is changed to
+</P>
+<P>
+<PRE>
+ ((?>\D+)|<\d+>)*[!?]
+</PRE>
+</P>
+<P>
+sequences of non-digits cannot be broken, and failure happens quickly.
+</P>
+<LI><A NAME="SEC26" HREF="#TOC1">CONDITIONAL SUBPATTERNS</A>
+<P>
+It is possible to cause the matching process to obey a subpattern
+conditionally or to choose between two alternative subpatterns, depending on
+the result of an assertion, or whether a previous capturing subpattern matched
+or not. The two possible forms of conditional subpattern are
+</P>
+<P>
+<PRE>
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+</PRE>
+</P>
+<P>
+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. If there are more than two alternatives in the
+subpattern, a compile-time error occurs.
+</P>
+<P>
+There are two kinds of condition. If the text between the parentheses consists
+of a sequence of digits, the condition is satisfied if the capturing subpattern
+of that number has previously matched. The number must be greater than zero.
+Consider the following pattern, which contains non-significant white space to
+make it more readable (assume the PCRE_EXTENDED option) and to divide it into
+three parts for ease of discussion:
+</P>
+<P>
+<PRE>
+ ( \( )? [^()]+ (?(1) \) )
+</PRE>
+</P>
+<P>
+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional subpattern that tests whether the first set of parentheses matched
+or not. If they did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing. In other words, this pattern matches a sequence of
+non-parentheses, optionally enclosed in parentheses.
+</P>
+<P>
+If the condition is not a sequence of digits, it must be an assertion. This may
+be a positive or negative lookahead or lookbehind assertion. Consider this
+pattern, again containing non-significant white space, and with the two
+alternatives on the second line:
+</P>
+<P>
+<PRE>
+ (?(?=[^a-z]*[a-z])
+ \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} )
+</PRE>
+</P>
+<P>
+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+</P>
+<LI><A NAME="SEC27" HREF="#TOC1">COMMENTS</A>
+<P>
+The sequence (?# marks the start of a comment which continues up to the next
+closing parenthesis. Nested parentheses are not permitted. The characters
+that make up a comment play no part in the pattern matching at all.
+</P>
+<P>
+If the PCRE_EXTENDED option is set, an unescaped # character outside a
+character class introduces a comment that continues up to the next newline
+character in the pattern.
+</P>
+<LI><A NAME="SEC28" HREF="#TOC1">RECURSIVE PATTERNS</A>
+<P>
+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth. Perl 5.6 has provided an
+experimental facility that allows regular expressions to recurse (amongst other
+things). It does this by interpolating Perl code in the expression at run time,
+and the code can refer to the expression itself. A Perl pattern to solve the
+parentheses problem can be created like this:
+</P>
+<P>
+<PRE>
+ $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+</PRE>
+</P>
+<P>
+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears. Obviously, PCRE cannot support
+the interpolation of Perl code. Instead, the special item (?R) is provided for
+the specific case of recursion. This PCRE pattern solves the parentheses
+problem (assume the PCRE_EXTENDED option is set so that white space is
+ignored):
+</P>
+<P>
+<PRE>
+ \( ( (?>[^()]+) | (?R) )* \)
+</PRE>
+</P>
+<P>
+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (i.e. a correctly parenthesized substring). Finally
+there is a closing parenthesis.
+</P>
+<P>
+This particular example pattern contains nested unlimited repeats, and so the
+use of a once-only subpattern for matching strings of non-parentheses is
+important when applying the pattern to strings that do not match. For example,
+when it is applied to
+</P>
+<P>
+<PRE>
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+</PRE>
+</P>
+<P>
+it yields "no match" quickly. However, if a once-only subpattern is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+</P>
+<P>
+The values set for any capturing subpatterns are those from the outermost level
+of the recursion at which the subpattern value is set. If the pattern above is
+matched against
+</P>
+<P>
+<PRE>
+ (ab(cd)ef)
+</PRE>
+</P>
+<P>
+the value for the capturing parentheses is "ef", which is the last value taken
+on at the top level. If additional parentheses are added, giving
+</P>
+<P>
+<PRE>
+ \( ( ( (?>[^()]+) | (?R) )* ) \)
+ ^ ^
+ ^ ^
+</PRE>
+the string they capture is "ab(cd)ef", the contents of the top level
+parentheses. If there are more than 15 capturing parentheses in a pattern, PCRE
+has to obtain extra memory to store data during a recursion, which it does by
+using <B>pcre_malloc</B>, freeing it via <B>pcre_free</B> afterwards. If no
+memory can be obtained, it saves data for the first 15 capturing parentheses
+only, as there is no way to give an out-of-memory error from within a
+recursion.
+</P>
+<LI><A NAME="SEC29" HREF="#TOC1">PERFORMANCE</A>
+<P>
+Certain items that may appear in patterns are more efficient than others. It is
+more efficient to use a character class like [aeiou] than a set of alternatives
+such as (a|e|i|o|u). In general, the simplest construction that provides the
+required behaviour is usually the most efficient. Jeffrey Friedl's book
+contains a lot of discussion about optimizing regular expressions for efficient
+performance.
+</P>
+<P>
+When a pattern begins with .* and the PCRE_DOTALL option is set, the pattern is
+implicitly anchored by PCRE, since it can match only at the start of a subject
+string. However, if PCRE_DOTALL is not set, PCRE cannot make this optimization,
+because the . metacharacter does not then match a newline, and if the subject
+string contains newlines, the pattern may match from the character immediately
+following one of them instead of from the very start. For example, the pattern
+</P>
+<P>
+<PRE>
+ (.*) second
+</PRE>
+</P>
+<P>
+matches the subject "first\nand second" (where \n stands for a newline
+character) with the first captured substring being "and". In order to do this,
+PCRE has to retry the match starting after every newline in the subject.
+</P>
+<P>
+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE_DOTALL, or starting
+the pattern with ^.* to indicate explicit anchoring. That saves PCRE from
+having to scan along the subject looking for a newline to restart at.
+</P>
+<P>
+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+</P>
+<P>
+<PRE>
+ (a+)*
+</PRE>
+</P>
+<P>
+This can match "aaaa" in 33 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE has in principle to try every possible
+variation, and this can take an extremely long time.
+</P>
+<P>
+An optimization catches some of the more simple cases such as
+</P>
+<P>
+<PRE>
+ (a+)*b
+</PRE>
+</P>
+<P>
+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+</P>
+<P>
+<PRE>
+ (a+)*\d
+</PRE>
+</P>
+<P>
+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+</P>
+<LI><A NAME="SEC30" HREF="#TOC1">UTF-8 SUPPORT</A>
+<P>
+Starting at release 3.3, PCRE has some support for character strings encoded
+in the UTF-8 format. This is incomplete, and is regarded as experimental. In
+order to use it, you must configure PCRE to include UTF-8 support in the code,
+and, in addition, you must call <B>pcre_compile()</B> with the PCRE_UTF8 option
+flag. When you do this, both the pattern and any subject strings that are
+matched against it are treated as UTF-8 strings instead of just strings of
+bytes, but only in the cases that are mentioned below.
+</P>
+<P>
+If you compile PCRE with UTF-8 support, but do not use it at run time, the
+library will be a bit bigger, but the additional run time overhead is limited
+to testing the PCRE_UTF8 flag in several places, so should not be very large.
+</P>
+<P>
+PCRE assumes that the strings it is given contain valid UTF-8 codes. It does
+not diagnose invalid UTF-8 strings. If you pass invalid UTF-8 strings to PCRE,
+the results are undefined.
+</P>
+<P>
+Running with PCRE_UTF8 set causes these changes in the way PCRE works:
+</P>
+<P>
+1. In a pattern, the escape sequence \x{...}, where the contents of the braces
+is a string of hexadecimal digits, is interpreted as a UTF-8 character whose
+code number is the given hexadecimal number, for example: \x{1234}. This
+inserts from one to six literal bytes into the pattern, using the UTF-8
+encoding. If a non-hexadecimal digit appears between the braces, the item is
+not recognized.
+</P>
+<P>
+2. The original hexadecimal escape sequence, \xhh, generates a two-byte UTF-8
+character if its value is greater than 127.
+</P>
+<P>
+3. Repeat quantifiers are NOT correctly handled if they follow a multibyte
+character. For example, \x{100}* and \xc3+ do not work. If you want to
+repeat such characters, you must enclose them in non-capturing parentheses,
+for example (?:\x{100}), at present.
+</P>
+<P>
+4. The dot metacharacter matches one UTF-8 character instead of a single byte.
+</P>
+<P>
+5. Unlike literal UTF-8 characters, the dot metacharacter followed by a
+repeat quantifier does operate correctly on UTF-8 characters instead of
+single bytes.
+</P>
+<P>
+4. Although the \x{...} escape is permitted in a character class, characters
+whose values are greater than 255 cannot be included in a class.
+</P>
+<P>
+5. A class is matched against a UTF-8 character instead of just a single byte,
+but it can match only characters whose values are less than 256. Characters
+with greater values always fail to match a class.
+</P>
+<P>
+6. Repeated classes work correctly on multiple characters.
+</P>
+<P>
+7. Classes containing just a single character whose value is greater than 127
+(but less than 256), for example, [\x80] or [^\x{93}], do not work because
+these are optimized into single byte matches. In the first case, of course,
+the class brackets are just redundant.
+</P>
+<P>
+8. Lookbehind assertions move backwards in the subject by a fixed number of
+characters instead of a fixed number of bytes. Simple cases have been tested
+to work correctly, but there may be hidden gotchas herein.
+</P>
+<P>
+9. The character types such as \d and \w do not work correctly with UTF-8
+characters. They continue to test a single byte.
+</P>
+<P>
+10. Anything not explicitly mentioned here continues to work in bytes rather
+than in characters.
+</P>
+<P>
+The following UTF-8 features of Perl 5.6 are not implemented:
+</P>
+<P>
+1. The escape sequence \C to match a single byte.
+</P>
+<P>
+2. The use of Unicode tables and properties and escapes \p, \P, and \X.

+DESCRIPTION
+ The PCRE library is a set of functions that implement regu-
+ lar expression pattern matching using the same syntax and
+ semantics as Perl 5, with just a few differences (see
+
+ below). The current implementation corresponds to Perl
+ 5.005, with some additional features from later versions.
+ This includes some experimental, incomplete support for
+ UTF-8 encoded strings. Details of exactly what is and what
+ is not supported are given below.
+
+ PCRE has its own native API, which is described in this
+ document. There is also a set of wrapper functions that
+ correspond to the POSIX regular expression API. These are
+ described in the pcreposix documentation.
+
+ The native API function prototypes are defined in the header
+ file pcre.h, and on Unix systems the library itself is
+ called libpcre.a, so can be accessed by adding -lpcre to the
+ command for linking an application which calls it. The
+ header file defines the macros PCRE_MAJOR and PCRE_MINOR to
+ contain the major and minor release numbers for the library.
+ Applications can use these to include support for different
+ releases.
+
+ The functions pcre_compile(), pcre_study(), and pcre_exec()
+ are used for compiling and matching regular expressions.
+
+ The functions pcre_copy_substring(), pcre_get_substring(),
+ and pcre_get_substring_list() are convenience functions for
+ extracting captured substrings from a matched subject
+ string; pcre_free_substring() and pcre_free_substring_list()
+ are also provided, to free the memory used for extracted
+ strings.
+
+ The function pcre_maketables() is used (optionally) to build
+ a set of character tables in the current locale for passing
+ to pcre_compile().
+
+ The function pcre_fullinfo() is used to find out information
+ about a compiled pattern; pcre_info() is an obsolete version
+ which returns only some of the available information, but is
+ retained for backwards compatibility. The function
+ pcre_version() returns a pointer to a string containing the
+ version of PCRE and its date of release.
+
+ The global variables pcre_malloc and pcre_free initially
+ contain the entry points of the standard malloc() and free()
+ functions respectively. PCRE calls the memory management

+ applications, with the proviso that the memory management
+ functions pointed to by pcre_malloc and pcre_free are shared
+ by all threads.
+
+ The compiled form of a regular expression is not altered
+ during matching, so the same compiled pattern can safely be
+ used by several threads at once.
+
+
+
+COMPILING A PATTERN
+ The function pcre_compile() is called to compile a pattern
+ into an internal form. The pattern is a C string terminated
+ by a binary zero, and is passed in the argument pattern. A
+ pointer to a single block of memory that is obtained via
+ pcre_malloc is returned. This contains the compiled code and
+ related data. The pcre type is defined for this for conveni-
+ ence, but in fact pcre is just a typedef for void, since the
+ contents of the block are not externally defined. It is up
+ to the caller to free the memory when it is no longer
+ required.
+
+ The size of a compiled pattern is roughly proportional to
+ the length of the pattern string, except that each character
+ class (other than those containing just a single character,
+ negated or not) requires 33 bytes, and repeat quantifiers
+ with a minimum greater than one or a bounded maximum cause
+ the relevant portions of the compiled pattern to be repli-
+ cated.
+
+ The options argument contains independent bits that affect
+ the compilation. It should be zero if no options are
+ required. Some of the options, in particular, those that are
+ compatible with Perl, can also be set and unset from within
+ the pattern (see the detailed description of regular expres-
+ sions below). For these options, the contents of the options
+ argument specifies their initial settings at the start of
+ compilation and execution. The PCRE_ANCHORED option can be
+ set at the time of matching as well as at compile time.
+
+ If errptr is NULL, pcre_compile() returns NULL immediately.
+ Otherwise, if compilation of a pattern fails, pcre_compile()
+ returns NULL, and sets the variable pointed to by errptr to
+ point to a textual error message. The offset from the start
+ of the pattern to the character where the error was
+ discovered is placed in the variable pointed to by
+ erroffset, which must not be NULL. If it is, an immediate
+ error is given.
+
+ If the final argument, tableptr, is NULL, PCRE uses a
+ default set of character tables which are built when it is
+ compiled, using the default C locale. Otherwise, tableptr
+ must be the result of a call to pcre_maketables(). See the
+ section on locale support below.
+
+ The following option bits are defined in the header file:
+
+ PCRE_ANCHORED
+
+ If this bit is set, the pattern is forced to be "anchored",
+ that is, it is constrained to match only at the start of the
+ string which is being searched (the "subject string"). This
+ effect can also be achieved by appropriate constructs in the
+ pattern itself, which is the only way to do it in Perl.
+
+ PCRE_CASELESS
+
+ If this bit is set, letters in the pattern match both upper
+ and lower case letters. It is equivalent to Perl's /i
+ option.
+
+ PCRE_DOLLAR_ENDONLY
+
+ If this bit is set, a dollar metacharacter in the pattern
+ matches only at the end of the subject string. Without this
+ option, a dollar also matches immediately before the final
+ character if it is a newline (but not before any other new-
+ lines). The PCRE_DOLLAR_ENDONLY option is ignored if
+ PCRE_MULTILINE is set. There is no equivalent to this option
+ in Perl.
+
+ PCRE_DOTALL
+
+ If this bit is set, a dot metacharater in the pattern
+ matches all characters, including newlines. Without it, new-
+ lines are excluded. This option is equivalent to Perl's /s
+ option. A negative class such as [^a] always matches a new-
+ line character, independent of the setting of this option.
+
+ PCRE_EXTENDED
+
+ If this bit is set, whitespace data characters in the pat-
+ tern are totally ignored except when escaped or inside a
+ character class, and characters between an unescaped # out-
+ side a character class and the next newline character,
+ inclusive, are also ignored. This is equivalent to Perl's /x
+ option, and makes it possible to include comments inside
+ complicated patterns. Note, however, that this applies only
+ to data characters. Whitespace characters may never appear
+ within special character sequences in a pattern, for example
+ within the sequence (?( which introduces a conditional sub-
+ pattern.
+
+ PCRE_EXTRA
+
+ This option was invented in order to turn on additional
+ functionality of PCRE that is incompatible with Perl, but it
+ is currently of very little use. When set, any backslash in
+ a pattern that is followed by a letter that has no special
+ meaning causes an error, thus reserving these combinations
+ for future expansion. By default, as in Perl, a backslash
+ followed by a letter with no special meaning is treated as a
+ literal. There are at present no other features controlled
+ by this option. It can also be set by a (?X) option setting
+ within a pattern.
+
+ PCRE_MULTILINE
+
+ By default, PCRE treats the subject string as consisting of
+ a single "line" of characters (even if it actually contains
+ several newlines). The "start of line" metacharacter (^)
+ matches only at the start of the string, while the "end of
+ line" metacharacter ($) matches only at the end of the
+ string, or before a terminating newline (unless
+ PCRE_DOLLAR_ENDONLY is set). This is the same as Perl.
+
+ When PCRE_MULTILINE it is set, the "start of line" and "end
+ of line" constructs match immediately following or immedi-
+ ately before any newline in the subject string, respec-
+ tively, as well as at the very start and end. This is
+ equivalent to Perl's /m option. If there are no "\n" charac-
+ ters in a subject string, or no occurrences of ^ or $ in a
+ pattern, setting PCRE_MULTILINE has no effect.
+
+ PCRE_UNGREEDY
+
+ This option inverts the "greediness" of the quantifiers so
+ that they are not greedy by default, but become greedy if
+ followed by "?". It is not compatible with Perl. It can also
+ be set by a (?U) option setting within the pattern.
+
+ PCRE_UTF8
+
+ This option causes PCRE to regard both the pattern and the
+ subject as strings of UTF-8 characters instead of just byte
+ strings. However, it is available only if PCRE has been
+ built to include UTF-8 support. If not, the use of this
+ option provokes an error. Support for UTF-8 is new, experi-
+ mental, and incomplete. Details of exactly what it entails
+ are given below.
+
+
+
+STUDYING A PATTERN
+ When a pattern is going to be used several times, it is
+ worth spending more time analyzing it in order to speed up
+ the time taken for matching. The function pcre_study() takes
+
+ a pointer to a compiled pattern as its first argument, and
+ returns a pointer to a pcre_extra block (another void
+ typedef) containing additional information about the pat-
+ tern; this can be passed to pcre_exec(). If no additional
+ information is available, NULL is returned.
+
+ The second argument contains option bits. At present, no
+ options are defined for pcre_study(), and this argument
+ should always be zero.
+
+ The third argument for pcre_study() is a pointer to an error
+ message. If studying succeeds (even if no data is returned),
+ the variable it points to is set to NULL. Otherwise it
+ points to a textual error message.
+
+ At present, studying a pattern is useful only for non-
+ anchored patterns that do not have a single fixed starting
+ character. A bitmap of possible starting characters is
+ created.
+
+
+
+LOCALE SUPPORT
+ PCRE handles caseless matching, and determines whether char-
+ acters are letters, digits, or whatever, by reference to a
+ set of tables. The library contains a default set of tables
+ which is created in the default C locale when PCRE is com-
+ piled. This is used when the final argument of
+ pcre_compile() is NULL, and is sufficient for many applica-
+ tions.
+
+ An alternative set of tables can, however, be supplied. Such
+ tables are built by calling the pcre_maketables() function,
+ which has no arguments, in the relevant locale. The result
+ can then be passed to pcre_compile() as often as necessary.
+ For example, to build and use tables that are appropriate
+ for the French locale (where accented characters with codes
+ greater than 128 are treated as letters), the following code
+ could be used:
+
+ setlocale(LC_CTYPE, "fr");
+ tables = pcre_maketables();
+ re = pcre_compile(..., tables);
+
+ The tables are built in memory that is obtained via
+ pcre_malloc. The pointer that is passed to pcre_compile is
+ saved with the compiled pattern, and the same tables are
+ used via this pointer by pcre_study() and pcre_exec(). Thus
+ for any single pattern, compilation, studying and matching
+ all happen in the same locale, but different patterns can be
+ compiled in different locales. It is the caller's responsi-
+ bility to ensure that the memory containing the tables
+ remains available for as long as it is needed.
+
+
+
+INFORMATION ABOUT A PATTERN
+ The pcre_fullinfo() function returns information about a
+ compiled pattern. It replaces the obsolete pcre_info() func-
+ tion, which is nevertheless retained for backwards compabil-
+ ity (and is documented below).
+
+ The first argument for pcre_fullinfo() is a pointer to the
+ compiled pattern. The second argument is the result of
+ pcre_study(), or NULL if the pattern was not studied. The
+ third argument specifies which piece of information is
+ required, while the fourth argument is a pointer to a vari-
+ able to receive the data. The yield of the function is zero
+ for success, or one of the following negative numbers:
+
+ PCRE_ERROR_NULL the argument code was NULL
+ the argument where was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+ PCRE_ERROR_BADOPTION the value of what was invalid
+
+ The possible values for the third argument are defined in
+ pcre.h, and are as follows:
+
+ PCRE_INFO_OPTIONS
+
+ Return a copy of the options with which the pattern was com-
+ piled. The fourth argument should point to au unsigned long
+ int variable. These option bits are those specified in the
+ call to pcre_compile(), modified by any top-level option
+ settings within the pattern itself, and with the
+ PCRE_ANCHORED bit forcibly set if the form of the pattern
+ implies that it can match only at the start of a subject
+ string.
+
+ PCRE_INFO_SIZE
+
+ Return the size of the compiled pattern, that is, the value
+ that was passed as the argument to pcre_malloc() when PCRE
+ was getting memory in which to place the compiled data. The
+ fourth argument should point to a size_t variable.
+
+ PCRE_INFO_CAPTURECOUNT
+
+ Return the number of capturing subpatterns in the pattern.
+ The fourth argument should point to an int variable.
+
+ PCRE_INFO_BACKREFMAX
+
+ Return the number of the highest back reference in the
+ pattern. The fourth argument should point to an int vari-
+ able. Zero is returned if there are no back references.
+
+ PCRE_INFO_FIRSTCHAR
+
+ Return information about the first character of any matched
+ string, for a non-anchored pattern. If there is a fixed
+ first character, e.g. from a pattern such as
+ (cat|cow|coyote), it is returned in the integer pointed to
+ by where. Otherwise, if either
+
+ (a) the pattern was compiled with the PCRE_MULTILINE option,
+ and every branch starts with "^", or
+
+ (b) every branch of the pattern starts with ".*" and
+ PCRE_DOTALL is not set (if it were set, the pattern would be
+ anchored),
+
+ -1 is returned, indicating that the pattern matches only at
+ the start of a subject string or after any "\n" within the
+ string. Otherwise -2 is returned. For anchored patterns, -2
+ is returned.
+
+ PCRE_INFO_FIRSTTABLE
+
+ If the pattern was studied, and this resulted in the con-
+ struction of a 256-bit table indicating a fixed set of char-
+ acters for the first character in any matching string, a
+ pointer to the table is returned. Otherwise NULL is
+ returned. The fourth argument should point to an unsigned
+ char * variable.
+
+ PCRE_INFO_LASTLITERAL
+
+ For a non-anchored pattern, return the value of the right-
+ most literal character which must exist in any matched
+ string, other than at its start. The fourth argument should
+ point to an int variable. If there is no such character, or
+ if the pattern is anchored, -1 is returned. For example, for
+ the pattern /a\d+z\d+/ the returned value is 'z'.
+
+ The pcre_info() function is now obsolete because its inter-
+ face is too restrictive to return all the available data
+ about a compiled pattern. New programs should use
+ pcre_fullinfo() instead. The yield of pcre_info() is the
+ number of capturing subpatterns, or one of the following
+ negative numbers:
+
+ PCRE_ERROR_NULL the argument code was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+
+ If the optptr argument is not NULL, a copy of the options
+ with which the pattern was compiled is placed in the integer
+ it points to (see PCRE_INFO_OPTIONS above).
+
+ If the pattern is not anchored and the firstcharptr argument
+ is not NULL, it is used to pass back information about the
+ first character of any matched string (see
+ PCRE_INFO_FIRSTCHAR above).
+
+
+
+MATCHING A PATTERN
+ The function pcre_exec() is called to match a subject string
+ against a pre-compiled pattern, which is passed in the code
+ argument. If the pattern has been studied, the result of the
+ study should be passed in the extra argument. Otherwise this
+ must be NULL.
+
+ The PCRE_ANCHORED option can be passed in the options argu-
+ ment, whose unused bits must be zero. However, if a pattern
+ was compiled with PCRE_ANCHORED, or turned out to be
+ anchored by virtue of its contents, it cannot be made
+ unachored at matching time.
+
+ There are also three further options that can be set only at
+ matching time:
+
+ PCRE_NOTBOL
+
+ The first character of the string is not the beginning of a
+ line, so the circumflex metacharacter should not match
+ before it. Setting this without PCRE_MULTILINE (at compile
+ time) causes circumflex never to match.
+
+ PCRE_NOTEOL
+
+ The end of the string is not the end of a line, so the dol-
+ lar metacharacter should not match it nor (except in multi-
+ line mode) a newline immediately before it. Setting this
+ without PCRE_MULTILINE (at compile time) causes dollar never
+ to match.
+
+ PCRE_NOTEMPTY
+
+ An empty string is not considered to be a valid match if
+ this option is set. If there are alternatives in the pat-
+ tern, they are tried. If all the alternatives match the
+ empty string, the entire match fails. For example, if the
+ pattern
+
+ a?b?
+
+ is applied to a string not beginning with "a" or "b", it
+ matches the empty string at the start of the subject. With
+ PCRE_NOTEMPTY set, this match is not valid, so PCRE searches
+ further into the string for occurrences of "a" or "b".
+
+ Perl has no direct equivalent of PCRE_NOTEMPTY, but it does
+ make a special case of a pattern match of the empty string
+ within its split() function, and when using the /g modifier.
+ It is possible to emulate Perl's behaviour after matching a
+ null string by first trying the match again at the same
+ offset with PCRE_NOTEMPTY set, and then if that fails by
+ advancing the starting offset (see below) and trying an
+ ordinary match again.
+
+ The subject string is passed as a pointer in subject, a
+ length in length, and a starting offset in startoffset.
+ Unlike the pattern string, it may contain binary zero char-
+ acters. When the starting offset is zero, the search for a
+ match starts at the beginning of the subject, and this is by
+ far the most common case.
+
+ A non-zero starting offset is useful when searching for
+ another match in the same subject by calling pcre_exec()
+ again after a previous success. Setting startoffset differs
+ from just passing over a shortened string and setting
+ PCRE_NOTBOL in the case of a pattern that begins with any
+ kind of lookbehind. For example, consider the pattern
+
+ \Biss\B
+
+ which finds occurrences of "iss" in the middle of words. (\B
+ matches only if the current position in the subject is not a
+ word boundary.) When applied to the string "Mississipi" the
+ first call to pcre_exec() finds the first occurrence. If
+ pcre_exec() is called again with just the remainder of the
+ subject, namely "issipi", it does not match, because \B is
+ always false at the start of the subject, which is deemed to
+ be a word boundary. However, if pcre_exec() is passed the
+ entire string again, but with startoffset set to 4, it finds
+ the second occurrence of "iss" because it is able to look
+ behind the starting point to discover that it is preceded by
+ a letter.
+
+ If a non-zero starting offset is passed when the pattern is
+ anchored, one attempt to match at the given offset is tried.
+ This can only succeed if the pattern does not require the
+ match to be at the start of the subject.
+
+ In general, a pattern matches a certain portion of the sub-
+ ject, and in addition, further substrings from the subject
+ may be picked out by parts of the pattern. Following the
+ usage in Jeffrey Friedl's book, this is called "capturing"
+ in what follows, and the phrase "capturing subpattern" is
+ used for a fragment of a pattern that picks out a substring.
+ PCRE supports several other kinds of parenthesized subpat-
+ tern that do not cause substrings to be captured.
+
+ Captured substrings are returned to the caller via a vector
+ of integer offsets whose address is passed in ovector. The
+ number of elements in the vector is passed in ovecsize. The
+ first two-thirds of the vector is used to pass back captured
+ substrings, each substring using a pair of integers. The
+ remaining third of the vector is used as workspace by
+ pcre_exec() while matching capturing subpatterns, and is not
+ available for passing back information. The length passed in
+ ovecsize should always be a multiple of three. If it is not,
+ it is rounded down.
+
+ When a match has been successful, information about captured
+ substrings is returned in pairs of integers, starting at the
+ beginning of ovector, and continuing up to two-thirds of its
+ length at the most. The first element of a pair is set to
+ the offset of the first character in a substring, and the
+ second is set to the offset of the first character after the
+ end of a substring. The first pair, ovector[0] and ovec-
+ tor[1], identify the portion of the subject string matched
+ by the entire pattern. The next pair is used for the first
+ capturing subpattern, and so on. The value returned by
+ pcre_exec() is the number of pairs that have been set. If
+ there are no capturing subpatterns, the return value from a
+ successful match is 1, indicating that just the first pair
+ of offsets has been set.
+
+ Some convenience functions are provided for extracting the
+ captured substrings as separate strings. These are described
+ in the following section.
+
+ It is possible for an capturing subpattern number n+1 to
+ match some part of the subject when subpattern n has not
+ been used at all. For example, if the string "abc" is
+ matched against the pattern (a|(z))(bc) subpatterns 1 and 3
+ are matched, but 2 is not. When this happens, both offset
+ values corresponding to the unused subpattern are set to -1.
+
+ If a capturing subpattern is matched repeatedly, it is the
+ last portion of the string that it matched that gets
+ returned.
+
+ If the vector is too small to hold all the captured sub-
+ strings, it is used as far as possible (up to two-thirds of
+ its length), and the function returns a value of zero. In
+ particular, if the substring offsets are not of interest,
+ pcre_exec() may be called with ovector passed as NULL and
+ ovecsize as zero. However, if the pattern contains back
+ references and the ovector isn't big enough to remember the
+ related substrings, PCRE has to get additional memory for
+ use during matching. Thus it is usually advisable to supply
+ an ovector.
+
+ Note that pcre_info() can be used to find out how many cap-
+ turing subpatterns there are in a compiled pattern. The
+ smallest size for ovector that will allow for n captured
+ substrings in addition to the offsets of the substring
+ matched by the whole pattern is (n+1)*3.
+
+ If pcre_exec() fails, it returns a negative number. The fol-
+ lowing are defined in the header file:
+
+ PCRE_ERROR_NOMATCH (-1)
+
+ The subject string did not match the pattern.
+
+ PCRE_ERROR_NULL (-2)
+
+ Either code or subject was passed as NULL, or ovector was
+ NULL and ovecsize was not zero.
+
+ PCRE_ERROR_BADOPTION (-3)
+
+ An unrecognized bit was set in the options argument.
+
+ PCRE_ERROR_BADMAGIC (-4)
+
+ PCRE stores a 4-byte "magic number" at the start of the com-
+ piled code, to catch the case when it is passed a junk
+ pointer. This is the error it gives when the magic number
+ isn't present.
+
+ PCRE_ERROR_UNKNOWN_NODE (-5)
+
+ While running the pattern match, an unknown item was encoun-
+ tered in the compiled pattern. This error could be caused by
+ a bug in PCRE or by overwriting of the compiled pattern.
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+ If a pattern contains back references, but the ovector that
+ is passed to pcre_exec() is not big enough to remember the
+ referenced substrings, PCRE gets a block of memory at the
+ start of matching to use for this purpose. If the call via
+ pcre_malloc() fails, this error is given. The memory is
+ freed at the end of matching.
+
+
+
+EXTRACTING CAPTURED SUBSTRINGS
+ Captured substrings can be accessed directly by using the
+
+
+
+
+
+SunOS 5.8 Last change: 12
+
+
+
+ offsets returned by pcre_exec() in ovector. For convenience,
+ the functions pcre_copy_substring(), pcre_get_substring(),
+ and pcre_get_substring_list() are provided for extracting
+ captured substrings as new, separate, zero-terminated
+ strings. A substring that contains a binary zero is
+ correctly extracted and has a further zero added on the end,
+ but the result does not, of course, function as a C string.
+
+ The first three arguments are the same for all three func-
+ tions: subject is the subject string which has just been
+ successfully matched, ovector is a pointer to the vector of
+ integer offsets that was passed to pcre_exec(), and
+ stringcount is the number of substrings that were captured
+ by the match, including the substring that matched the
+ entire regular expression. This is the value returned by
+ pcre_exec if it is greater than zero. If pcre_exec()
+ returned zero, indicating that it ran out of space in ovec-
+ tor, the value passed as stringcount should be the size of
+ the vector divided by three.
+
+ The functions pcre_copy_substring() and pcre_get_substring()
+ extract a single substring, whose number is given as string-
+ number. A value of zero extracts the substring that matched
+ the entire pattern, while higher values extract the captured
+ substrings. For pcre_copy_substring(), the string is placed
+ in buffer, whose length is given by buffersize, while for
+ pcre_get_substring() a new block of memory is obtained via
+ pcre_malloc, and its address is returned via stringptr. The
+ yield of the function is the length of the string, not
+ including the terminating zero, or one of
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+ The buffer was too small for pcre_copy_substring(), or the
+ attempt to get memory failed for pcre_get_substring().
+
+ PCRE_ERROR_NOSUBSTRING (-7)
+
+ There is no substring whose number is stringnumber.
+
+ The pcre_get_substring_list() function extracts all avail-
+ able substrings and builds a list of pointers to them. All
+ this is done in a single block of memory which is obtained
+ via pcre_malloc. The address of the memory block is returned
+ via listptr, which is also the start of the list of string
+ pointers. The end of the list is marked by a NULL pointer.
+ The yield of the function is zero if all went well, or
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+ if the attempt to get the memory block failed.
+
+ When any of these functions encounter a substring that is
+ unset, which can happen when capturing subpattern number n+1
+ matches some part of the subject, but subpattern n has not
+ been used at all, they return an empty string. This can be
+ distinguished from a genuine zero-length substring by
+ inspecting the appropriate offset in ovector, which is nega-
+ tive for unset substrings.
+
+ The two convenience functions pcre_free_substring() and
+ pcre_free_substring_list() can be used to free the memory
+ returned by a previous call of pcre_get_substring() or
+ pcre_get_substring_list(), respectively. They do nothing
+ more than call the function pointed to by pcre_free, which
+ of course could be called directly from a C program. How-
+ ever, PCRE is used in some situations where it is linked via
+ a special interface to another programming language which
+ cannot use pcre_free directly; it is for these cases that
+ the functions are provided.
+
+
+
+LIMITATIONS
+ There are some size limitations in PCRE but it is hoped that
+ they will never in practice be relevant. The maximum length
+ of a compiled pattern is 65539 (sic) bytes. All values in
+ repeating quantifiers must be less than 65536. The maximum
+ number of capturing subpatterns is 99. The maximum number
+ of all parenthesized subpatterns, including capturing sub-
+ patterns, assertions, and other types of subpattern, is 200.
+
+ The maximum length of a subject string is the largest posi-
+ tive number that an integer variable can hold. However, PCRE
+ uses recursion to handle subpatterns and indefinite repeti-
+ tion. This means that the available stack space may limit
+ the size of a subject string that can be processed by cer-
+ tain patterns.
+
+
+
+DIFFERENCES FROM PERL
+ The differences described here are with respect to Perl
+ 5.005.
+
+ 1. By default, a whitespace character is any character that
+ the C library function isspace() recognizes, though it is
+ possible to compile PCRE with alternative character type
+ tables. Normally isspace() matches space, formfeed, newline,
+ carriage return, horizontal tab, and vertical tab. Perl 5 no
+ longer includes vertical tab in its set of whitespace char-
+ acters. The \v escape that was in the Perl documentation for
+ a long time was never in fact recognized. However, the char-
+ acter itself was treated as whitespace at least up to 5.002.
+ In 5.004 and 5.005 it does not match \s.
+
+ 2. PCRE does not allow repeat quantifiers on lookahead
+ assertions. Perl permits them, but they do not mean what you
+ might think. For example, (?!a){3} does not assert that the
+ next three characters are not "a". It just asserts that the
+ next character is not "a" three times.
+
+ 3. Capturing subpatterns that occur inside negative looka-
+ head assertions are counted, but their entries in the
+ offsets vector are never set. Perl sets its numerical vari-
+ ables from any such patterns that are matched before the
+ assertion fails to match something (thereby succeeding), but
+ only if the negative lookahead assertion contains just one
+ branch.
+
+ 4. Though binary zero characters are supported in the sub-
+ ject string, they are not allowed in a pattern string
+ because it is passed as a normal C string, terminated by
+ zero. The escape sequence "\0" can be used in the pattern to
+ represent a binary zero.
+
+ 5. The following Perl escape sequences are not supported:
+ \l, \u, \L, \U, \E, \Q. In fact these are implemented by
+ Perl's general string-handling and are not part of its pat-
+ tern matching engine.
+
+ 6. The Perl \G assertion is not supported as it is not
+ relevant to single pattern matches.
+
+ 7. Fairly obviously, PCRE does not support the (?{code}) and
+ (?p{code}) constructions. However, there is some experimen-
+ tal support for recursive patterns using the non-Perl item
+ (?R).
+
+ 8. There are at the time of writing some oddities in Perl
+ 5.005_02 concerned with the settings of captured strings
+ when part of a pattern is repeated. For example, matching
+ "aba" against the pattern /^(a(b)?)+$/ sets $2 to the value
+ "b", but matching "aabbaa" against /^(aa(bb)?)+$/ leaves $2
+ unset. However, if the pattern is changed to
+ /^(aa(b(b))?)+$/ then $2 (and $3) are set.
+
+ In Perl 5.004 $2 is set in both cases, and that is also true
+ of PCRE. If in the future Perl changes to a consistent state
+ that is different, PCRE may change to follow.
+
+ 9. Another as yet unresolved discrepancy is that in Perl
+ 5.005_02 the pattern /^(a)?(?(1)a|b)+$/ matches the string
+ "a", whereas in PCRE it does not. However, in both Perl and
+ PCRE /^(a)?a/ matched against "a" leaves $1 unset.
+
+ 10. PCRE provides some extensions to the Perl regular
+ expression facilities:
+
+ (a) Although lookbehind assertions must match fixed length
+ strings, each alternative branch of a lookbehind assertion
+ can match a different length of string. Perl 5.005 requires
+ them all to have the same length.
+
+ (b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not
+ set, the $ meta- character matches only at the very end of
+ the string.
+
+ (c) If PCRE_EXTRA is set, a backslash followed by a letter
+ with no special meaning is faulted.
+
+ (d) If PCRE_UNGREEDY is set, the greediness of the repeti-
+ tion quantifiers is inverted, that is, by default they are
+ not greedy, but if followed by a question mark they are.
+
+ (e) PCRE_ANCHORED can be used to force a pattern to be tried
+ only at the start of the subject.
+
+ (f) The PCRE_NOTBOL, PCRE_NOTEOL, and PCRE_NOTEMPTY options
+ for pcre_exec() have no Perl equivalents.
+
+ (g) The (?R) construct allows for recursive pattern matching
+ (Perl 5.6 can do this using the (?p{code}) construct, which
+ PCRE cannot of course support.)
+
+
+
+REGULAR EXPRESSION DETAILS
+ The syntax and semantics of the regular expressions sup-
+ ported by PCRE are described below. Regular expressions are
+ also described in the Perl documentation and in a number of
+ other books, some of which have copious examples. Jeffrey
+ Friedl's "Mastering Regular Expressions", published by
+ O'Reilly (ISBN 1-56592-257), covers them in great detail.
+
+ The description here is intended as reference documentation.
+ The basic operation of PCRE is on strings of bytes. However,
+ there is the beginnings of some support for UTF-8 character
+ strings. To use this support you must configure PCRE to
+ include it, and then call pcre_compile() with the PCRE_UTF8
+ option. How this affects the pattern matching is described
+ in the final section of this document.
+
+ A regular expression is a pattern that is matched against a
+ subject string from left to right. Most characters stand for
+ themselves in a pattern, and match the corresponding charac-
+ ters in the subject. As a trivial example, the pattern
+
+ The quick brown fox
+
+ matches a portion of a subject string that is identical to
+ itself. The power of regular expressions comes from the
+ ability to include alternatives and repetitions in the pat-
+ tern. These are encoded in the pattern by the use of meta-
+ characters, which do not stand for themselves but instead
+ are interpreted in some special way.
+
+ There are two different sets of meta-characters: those that
+ are recognized anywhere in the pattern except within square
+ brackets, and those that are recognized in square brackets.
+ Outside square brackets, the meta-characters are as follows:
+
+ \ general escape character with several uses
+ ^ assert start of subject (or line, in multiline
+ mode)
+ $ assert end of subject (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ { start min/max quantifier
+
+ Part of a pattern that is in square brackets is called a
+ "character class". In a character class the only meta-
+ characters are:
+
+ \ general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+ ] terminates the character class
+
+ The following sections describe the use of each of the
+ meta-characters.
+
+
+
+BACKSLASH
+ The backslash character has several uses. Firstly, if it is
+ followed by a non-alphameric character, it takes away any
+ special meaning that character may have. This use of
+ backslash as an escape character applies both inside and
+ outside character classes.
+
+ For example, if you want to match a "*" character, you write
+ "\*" in the pattern. This applies whether or not the follow-
+ ing character would otherwise be interpreted as a meta-
+ character, so it is always safe to precede a non-alphameric
+ with "\" to specify that it stands for itself. In particu-
+ lar, if you want to match a backslash, you write "\\".
+
+ If a pattern is compiled with the PCRE_EXTENDED option, whi-
+ tespace in the pattern (other than in a character class) and
+ characters between a "#" outside a character class and the
+ next newline character are ignored. An escaping backslash
+ can be used to include a whitespace or "#" character as part
+ of the pattern.
+
+ A second use of backslash provides a way of encoding non-
+ printing characters in patterns in a visible manner. There
+ is no restriction on the appearance of non-printing charac-
+ ters, apart from the binary zero that terminates a pattern,
+ but when a pattern is being prepared by text editing, it is
+ usually easier to use one of the following escape sequences
+ than the binary character it represents:
+
+ \a alarm, that is, the BEL character (hex 07)
+ \cx "control-x", where x is any character
+ \e escape (hex 1B)
+ \f formfeed (hex 0C)
+ \n newline (hex 0A)
+ \r carriage return (hex 0D)
+ \t tab (hex 09)
+ \xhh character with hex code hh
+ \ddd character with octal code ddd, or backreference
+
+ The precise effect of "\cx" is as follows: if "x" is a lower
+ case letter, it is converted to upper case. Then bit 6 of
+ the character (hex 40) is inverted. Thus "\cz" becomes hex
+ 1A, but "\c{" becomes hex 3B, while "\c;" becomes hex 7B.
+
+ After "\x", up to two hexadecimal digits are read (letters
+ can be in upper or lower case).
+
+ After "\0" up to two further octal digits are read. In both
+ cases, if there are fewer than two digits, just those that
+ are present are used. Thus the sequence "\0\x\07" specifies
+ two binary zeros followed by a BEL character. Make sure you
+ supply two digits after the initial zero if the character
+ that follows is itself an octal digit.
+
+ The handling of a backslash followed by a digit other than 0
+ is complicated. Outside a character class, PCRE reads it
+ and any following digits as a decimal number. If the number
+ is less than 10, or if there have been at least that many
+ previous capturing left parentheses in the expression, the
+ entire sequence is taken as a back reference. A description
+ of how this works is given later, following the discussion
+ of parenthesized subpatterns.
+
+ Inside a character class, or if the decimal number is
+ greater than 9 and there have not been that many capturing
+ subpatterns, PCRE re-reads up to three octal digits follow-
+ ing the backslash, and generates a single byte from the
+ least significant 8 bits of the value. Any subsequent digits
+ stand for themselves. For example:
+
+ \040 is another way of writing a space
+ \40 is the same, provided there are fewer than 40
+ previous capturing subpatterns
+ \7 is always a back reference
+ \11 might be a back reference, or another way of
+ writing a tab
+ \011 is always a tab
+ \0113 is a tab followed by the character "3"
+ \113 is the character with octal code 113 (since there
+ can be no more than 99 back references)
+ \377 is a byte consisting entirely of 1 bits
+ \81 is either a back reference, or a binary zero
+ followed by the two characters "8" and "1"
+
+ Note that octal values of 100 or greater must not be intro-
+ duced by a leading zero, because no more than three octal
+ digits are ever read.
+
+ All the sequences that define a single byte value can be
+ used both inside and outside character classes. In addition,
+ inside a character class, the sequence "\b" is interpreted
+ as the backspace character (hex 08). Outside a character
+ class it has a different meaning (see below).
+
+ The third use of backslash is for specifying generic charac-
+ ter types:
+
+ \d any decimal digit
+ \D any character that is not a decimal digit
+ \s any whitespace character
+ \S any character that is not a whitespace character
+ \w any "word" character
+ \W any "non-word" character
+
+ Each pair of escape sequences partitions the complete set of
+ characters into two disjoint sets. Any given character
+ matches one, and only one, of each pair.
+
+ A "word" character is any letter or digit or the underscore
+ character, that is, any character which can be part of a
+ Perl "word". The definition of letters and digits is con-
+ trolled by PCRE's character tables, and may vary if locale-
+ specific matching is taking place (see "Locale support"
+ above). For example, in the "fr" (French) locale, some char-
+ acter codes greater than 128 are used for accented letters,
+ and these are matched by \w.
+
+ These character type sequences can appear both inside and
+ outside character classes. They each match one character of
+ the appropriate type. If the current matching point is at
+ the end of the subject string, all of them fail, since there
+ is no character to match.
+
+ The fourth use of backslash is for certain simple asser-
+ tions. An assertion specifies a condition that has to be met
+ at a particular point in a match, without consuming any
+ characters from the subject string. The use of subpatterns
+ for more complicated assertions is described below. The
+ backslashed assertions are
+
+ \b word boundary
+ \B not a word boundary
+ \A start of subject (independent of multiline mode)
+ \Z end of subject or newline at end (independent of
+ multiline mode)
+ \z end of subject (independent of multiline mode)
+
+ These assertions may not appear in character classes (but
+ note that "\b" has a different meaning, namely the backspace
+ character, inside a character class).
+
+ A word boundary is a position in the subject string where
+ the current character and the previous character do not both
+ match \w or \W (i.e. one matches \w and the other matches
+ \W), or the start or end of the string if the first or last
+ character matches \w, respectively.
+
+ The \A, \Z, and \z assertions differ from the traditional
+ circumflex and dollar (described below) in that they only
+ ever match at the very start and end of the subject string,
+ whatever options are set. They are not affected by the
+ PCRE_NOTBOL or PCRE_NOTEOL options. If the startoffset argu-
+ ment of pcre_exec() is non-zero, \A can never match. The
+ difference between \Z and \z is that \Z matches before a
+ newline that is the last character of the string as well as
+ at the end of the string, whereas \z matches only at the
+ end.
+
+
+
+CIRCUMFLEX AND DOLLAR
+ Outside a character class, in the default matching mode, the
+ circumflex character is an assertion which is true only if
+ the current matching point is at the start of the subject
+
+ string. If the startoffset argument of pcre_exec() is non-
+ zero, circumflex can never match. Inside a character class,
+ circumflex has an entirely different meaning (see below).
+
+ Circumflex need not be the first character of the pattern if
+ a number of alternatives are involved, but it should be the
+ first thing in each alternative in which it appears if the
+ pattern is ever to match that branch. If all possible alter-
+ natives start with a circumflex, that is, if the pattern is
+ constrained to match only at the start of the subject, it is
+ said to be an "anchored" pattern. (There are also other con-
+ structs that can cause a pattern to be anchored.)
+
+ A dollar character is an assertion which is true only if the
+ current matching point is at the end of the subject string,
+ or immediately before a newline character that is the last
+ character in the string (by default). Dollar need not be the
+ last character of the pattern if a number of alternatives
+ are involved, but it should be the last item in any branch
+ in which it appears. Dollar has no special meaning in a
+ character class.
+
+ The meaning of dollar can be changed so that it matches only
+ at the very end of the string, by setting the
+ PCRE_DOLLAR_ENDONLY option at compile or matching time. This
+ does not affect the \Z assertion.
+
+ The meanings of the circumflex and dollar characters are
+ changed if the PCRE_MULTILINE option is set. When this is
+ the case, they match immediately after and immediately
+ before an internal "\n" character, respectively, in addition
+ to matching at the start and end of the subject string. For
+ example, the pattern /^abc$/ matches the subject string
+ "def\nabc" in multiline mode, but not otherwise. Conse-
+ quently, patterns that are anchored in single line mode
+ because all branches start with "^" are not anchored in mul-
+ tiline mode, and a match for circumflex is possible when the
+ startoffset argument of pcre_exec() is non-zero. The
+ PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is
+ set.
+
+ Note that the sequences \A, \Z, and \z can be used to match
+ the start and end of the subject in both modes, and if all
+ branches of a pattern start with \A is it always anchored,
+ whether PCRE_MULTILINE is set or not.
+
+
+
+FULL STOP (PERIOD, DOT)
+ Outside a character class, a dot in the pattern matches any
+ one character in the subject, including a non-printing char-
+ acter, but not (by default) newline. If the PCRE_DOTALL
+
+ option is set, dots match newlines as well. The handling of
+ dot is entirely independent of the handling of circumflex
+ and dollar, the only relationship being that they both
+ involve newline characters. Dot has no special meaning in a
+ character class.
+
+
+
+SQUARE BRACKETS
+ An opening square bracket introduces a character class, ter-
+ minated by a closing square bracket. A closing square
+ bracket on its own is not special. If a closing square
+ bracket is required as a member of the class, it should be
+ the first data character in the class (after an initial cir-
+ cumflex, if present) or escaped with a backslash.
+
+ A character class matches a single character in the subject;
+ the character must be in the set of characters defined by
+ the class, unless the first character in the class is a cir-
+ cumflex, in which case the subject character must not be in
+ the set defined by the class. If a circumflex is actually
+ required as a member of the class, ensure it is not the
+ first character, or escape it with a backslash.
+
+ For example, the character class [aeiou] matches any lower
+ case vowel, while [^aeiou] matches any character that is not
+ a lower case vowel. Note that a circumflex is just a con-
+ venient notation for specifying the characters which are in
+ the class by enumerating those that are not. It is not an
+ assertion: it still consumes a character from the subject
+ string, and fails if the current pointer is at the end of
+ the string.
+
+ When caseless matching is set, any letters in a class
+ represent both their upper case and lower case versions, so
+ for example, a caseless [aeiou] matches "A" as well as "a",
+ and a caseless [^aeiou] does not match "A", whereas a case-
+ ful version would.
+
+ The newline character is never treated in any special way in
+ character classes, whatever the setting of the PCRE_DOTALL
+ or PCRE_MULTILINE options is. A class such as [^a] will
+ always match a newline.
+
+ The minus (hyphen) character can be used to specify a range
+ of characters in a character class. For example, [d-m]
+ matches any letter between d and m, inclusive. If a minus
+ character is required in a class, it must be escaped with a
+ backslash or appear in a position where it cannot be inter-
+ preted as indicating a range, typically as the first or last
+ character in the class.
+
+ It is not possible to have the literal character "]" as the
+ end character of a range. A pattern such as [W-]46] is
+ interpreted as a class of two characters ("W" and "-") fol-
+ lowed by a literal string "46]", so it would match "W46]" or
+ "-46]". However, if the "]" is escaped with a backslash it
+ is interpreted as the end of range, so [W-\]46] is inter-
+ preted as a single class containing a range followed by two
+ separate characters. The octal or hexadecimal representation
+ of "]" can also be used to end a range.
+
+ Ranges operate in ASCII collating sequence. They can also be
+ used for characters specified numerically, for example
+ [\000-\037]. If a range that includes letters is used when
+ caseless matching is set, it matches the letters in either
+ case. For example, [W-c] is equivalent to [][\^_`wxyzabc],
+ matched caselessly, and if character tables for the "fr"
+ locale are in use, [\xc8-\xcb] matches accented E characters
+ in both cases.
+
+ The character types \d, \D, \s, \S, \w, and \W may also
+ appear in a character class, and add the characters that
+ they match to the class. For example, [\dABCDEF] matches any
+ hexadecimal digit. A circumflex can conveniently be used
+ with the upper case character types to specify a more res-
+ tricted set of characters than the matching lower case type.
+ For example, the class [^\W_] matches any letter or digit,
+ but not underscore.
+
+ All non-alphameric characters other than \, -, ^ (at the
+ start) and the terminating ] are non-special in character
+ classes, but it does no harm if they are escaped.
+
+
+
+POSIX CHARACTER CLASSES
+ Perl 5.6 (not yet released at the time of writing) is going
+ to support the POSIX notation for character classes, which
+ uses names enclosed by [: and :] within the enclosing
+ square brackets. PCRE supports this notation. For example,
+
+ [01[:alpha:]%]
+
+ matches "0", "1", any alphabetic character, or "%". The sup-
+ ported class names are
+
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ cntrl control characters
+ digit decimal digits (same as \d)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits
+ space white space (same as \s)
+ upper upper case letters
+ word "word" characters (same as \w)
+ xdigit hexadecimal digits
+
+ The names "ascii" and "word" are Perl extensions. Another
+ Perl extension is negation, which is indicated by a ^ char-
+ acter after the colon. For example,
+
+ [12[:^digit:]]
+
+ matches "1", "2", or any non-digit. PCRE (and Perl) also
+ recogize the POSIX syntax [.ch.] and [=ch=] where "ch" is a
+ "collating element", but these are not supported, and an
+ error is given if they are encountered.
+
+
+
+VERTICAL BAR
+ Vertical bar characters are used to separate alternative
+ patterns. For example, the pattern
+
+ gilbert|sullivan
+
+ matches either "gilbert" or "sullivan". Any number of alter-
+ natives may appear, and an empty alternative is permitted
+ (matching the empty string). The matching process tries
+ each alternative in turn, from left to right, and the first
+ one that succeeds is used. If the alternatives are within a
+ subpattern (defined below), "succeeds" means matching the
+ rest of the main pattern as well as the alternative in the
+ subpattern.
+
+
+
+INTERNAL OPTION SETTING
+ The settings of PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL,
+ and PCRE_EXTENDED can be changed from within the pattern by
+ a sequence of Perl option letters enclosed between "(?" and
+ ")". The option letters are
+
+ i for PCRE_CASELESS
+ m for PCRE_MULTILINE
+ s for PCRE_DOTALL
+ x for PCRE_EXTENDED
+
+ For example, (?im) sets caseless, multiline matching. It is
+ also possible to unset these options by preceding the letter
+ with a hyphen, and a combined setting and unsetting such as
+ (?im-sx), which sets PCRE_CASELESS and PCRE_MULTILINE while
+ unsetting PCRE_DOTALL and PCRE_EXTENDED, is also permitted.
+ If a letter appears both before and after the hyphen, the
+ option is unset.
+
+ The scope of these option changes depends on where in the
+ pattern the setting occurs. For settings that are outside
+ any subpattern (defined below), the effect is the same as if
+ the options were set or unset at the start of matching. The
+ following patterns all behave in exactly the same way:
+
+ (?i)abc
+ a(?i)bc
+ ab(?i)c
+ abc(?i)
+
+ which in turn is the same as compiling the pattern abc with
+ PCRE_CASELESS set. In other words, such "top level" set-
+ tings apply to the whole pattern (unless there are other
+ changes inside subpatterns). If there is more than one set-
+ ting of the same option at top level, the rightmost setting
+ is used.
+
+ If an option change occurs inside a subpattern, the effect
+ is different. This is a change of behaviour in Perl 5.005.
+ An option change inside a subpattern affects only that part
+ of the subpattern that follows it, so
+
+ (a(?i)b)c
+
+ matches abc and aBc and no other strings (assuming
+ PCRE_CASELESS is not used). By this means, options can be
+ made to have different settings in different parts of the
+ pattern. Any changes made in one alternative do carry on
+ into subsequent branches within the same subpattern. For
+ example,
+
+ (a(?i)b|c)
+
+ matches "ab", "aB", "c", and "C", even though when matching
+ "C" the first branch is abandoned before the option setting.
+ This is because the effects of option settings happen at
+ compile time. There would be some very weird behaviour oth-
+ erwise.
+
+ The PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA can
+ be changed in the same way as the Perl-compatible options by
+ using the characters U and X respectively. The (?X) flag
+ setting is special in that it must always occur earlier in
+ the pattern than any of the additional features it turns on,
+ even when it is at top level. It is best put at the start.
+
+
+
+SUBPATTERNS
+ Subpatterns are delimited by parentheses (round brackets),
+ which can be nested. Marking part of a pattern as a subpat-
+ tern does two things:
+
+ 1. It localizes a set of alternatives. For example, the pat-
+ tern
+
+ cat(aract|erpillar|)
+
+ matches one of the words "cat", "cataract", or "caterpil-
+ lar". Without the parentheses, it would match "cataract",
+ "erpillar" or the empty string.
+
+ 2. It sets up the subpattern as a capturing subpattern (as
+ defined above). When the whole pattern matches, that por-
+ tion of the subject string that matched the subpattern is
+ passed back to the caller via the ovector argument of
+ pcre_exec(). Opening parentheses are counted from left to
+ right (starting from 1) to obtain the numbers of the captur-
+ ing subpatterns.
+
+ For example, if the string "the red king" is matched against
+ the pattern
+
+ the ((red|white) (king|queen))
+
+ the captured substrings are "red king", "red", and "king",
+ and are numbered 1, 2, and 3.
+
+ The fact that plain parentheses fulfil two functions is not
+ always helpful. There are often times when a grouping sub-
+ pattern is required without a capturing requirement. If an
+ opening parenthesis is followed by "?:", the subpattern does
+ not do any capturing, and is not counted when computing the
+ number of any subsequent capturing subpatterns. For example,
+ if the string "the white queen" is matched against the pat-
+ tern
+
+ the ((?:red|white) (king|queen))
+
+ the captured substrings are "white queen" and "queen", and
+ are numbered 1 and 2. The maximum number of captured sub-
+ strings is 99, and the maximum number of all subpatterns,
+ both capturing and non-capturing, is 200.
+
+ As a convenient shorthand, if any option settings are
+ required at the start of a non-capturing subpattern, the
+ option letters may appear between the "?" and the ":". Thus
+ the two patterns
+
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+
+ match exactly the same set of strings. Because alternative
+ branches are tried from left to right, and options are not
+ reset until the end of the subpattern is reached, an option
+ setting in one branch does affect subsequent branches, so
+ the above patterns match "SUNDAY" as well as "Saturday".
+
+
+
+REPETITION
+ Repetition is specified by quantifiers, which can follow any
+ of the following items:
+
+ a single character, possibly escaped
+ the . metacharacter
+ a character class
+ a back reference (see next section)
+ a parenthesized subpattern (unless it is an assertion -
+ see below)
+
+ The general repetition quantifier specifies a minimum and
+ maximum number of permitted matches, by giving the two
+ numbers in curly brackets (braces), separated by a comma.
+ The numbers must be less than 65536, and the first must be
+ less than or equal to the second. For example:
+
+ z{2,4}
+
+ matches "zz", "zzz", or "zzzz". A closing brace on its own
+ is not a special character. If the second number is omitted,
+ but the comma is present, there is no upper limit; if the
+ second number and the comma are both omitted, the quantifier
+ specifies an exact number of required matches. Thus
+
+ [aeiou]{3,}
+
+ matches at least 3 successive vowels, but may match many
+ more, while
+
+ \d{8}
+
+ matches exactly 8 digits. An opening curly bracket that
+ appears in a position where a quantifier is not allowed, or
+ one that does not match the syntax of a quantifier, is taken
+ as a literal character. For example, {,6} is not a quantif-
+ ier, but a literal string of four characters.
+
+ The quantifier {0} is permitted, causing the expression to
+ behave as if the previous item and the quantifier were not
+ present.
+
+ For convenience (and historical compatibility) the three
+ most common quantifiers have single-character abbreviations:
+
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+
+ It is possible to construct infinite loops by following a
+ subpattern that can match no characters with a quantifier
+ that has no upper limit, for example:
+
+ (a?)*
+
+ Earlier versions of Perl and PCRE used to give an error at
+ compile time for such patterns. However, because there are
+ cases where this can be useful, such patterns are now
+ accepted, but if any repetition of the subpattern does in
+ fact match no characters, the loop is forcibly broken.
+
+ By default, the quantifiers are "greedy", that is, they
+ match as much as possible (up to the maximum number of per-
+ mitted times), without causing the rest of the pattern to
+ fail. The classic example of where this gives problems is in
+ trying to match comments in C programs. These appear between
+ the sequences /* and */ and within the sequence, individual
+ * and / characters may appear. An attempt to match C com-
+ ments by applying the pattern
+
+ /\*.*\*/
+
+ to the string
+
+ /* first command */ not comment /* second comment */
+
+ fails, because it matches the entire string owing to the
+ greediness of the .* item.
+
+ However, if a quantifier is followed by a question mark, it
+ ceases to be greedy, and instead matches the minimum number
+ of times possible, so the pattern
+
+ /\*.*?\*/
+
+ does the right thing with the C comments. The meaning of the
+ various quantifiers is not otherwise changed, just the pre-
+ ferred number of matches. Do not confuse this use of ques-
+ tion mark with its use as a quantifier in its own right.
+ Because it has two uses, it can sometimes appear doubled, as
+ in
+
+ \d??\d
+
+ which matches one digit by preference, but can match two if
+ that is the only way the rest of the pattern matches.
+
+ If the PCRE_UNGREEDY option is set (an option which is not
+ available in Perl), the quantifiers are not greedy by
+ default, but individual ones can be made greedy by following
+ them with a question mark. In other words, it inverts the
+ default behaviour.
+
+ When a parenthesized subpattern is quantified with a minimum
+ repeat count that is greater than 1 or with a limited max-
+ imum, more store is required for the compiled pattern, in
+ proportion to the size of the minimum or maximum.
+
+ If a pattern starts with .* or .{0,} and the PCRE_DOTALL
+ option (equivalent to Perl's /s) is set, thus allowing the .
+ to match newlines, the pattern is implicitly anchored,
+ because whatever follows will be tried against every charac-
+ ter position in the subject string, so there is no point in
+ retrying the overall match at any position after the first.
+ PCRE treats such a pattern as though it were preceded by \A.
+ In cases where it is known that the subject string contains
+ no newlines, it is worth setting PCRE_DOTALL when the pat-
+ tern begins with .* in order to obtain this optimization, or
+ alternatively using ^ to indicate anchoring explicitly.
+
+ When a capturing subpattern is repeated, the value captured
+ is the substring that matched the final iteration. For exam-
+ ple, after
+
+ (tweedle[dume]{3}\s*)+
+
+ has matched "tweedledum tweedledee" the value of the cap-
+ tured substring is "tweedledee". However, if there are
+ nested capturing subpatterns, the corresponding captured
+ values may have been set in previous iterations. For exam-
+ ple, after
+
+ /(a|(b))+/
+
+ matches "aba" the value of the second captured substring is
+ "b".
+
+
+
+BACK REFERENCES
+ Outside a character class, a backslash followed by a digit
+ greater than 0 (and possibly further digits) is a back
+ reference to a capturing subpattern earlier (i.e. to its
+ left) in the pattern, provided there have been that many
+ previous capturing left parentheses.
+
+ However, if the decimal number following the backslash is
+ less than 10, it is always taken as a back reference, and
+ causes an error only if there are not that many capturing
+ left parentheses in the entire pattern. In other words, the
+ parentheses that are referenced need not be to the left of
+ the reference for numbers less than 10. See the section
+ entitled "Backslash" above for further details of the han-
+ dling of digits following a backslash.
+
+ A back reference matches whatever actually matched the cap-
+ turing subpattern in the current subject string, rather than
+ anything matching the subpattern itself. So the pattern
+
+ (sens|respons)e and \1ibility
+
+ matches "sense and sensibility" and "response and responsi-
+ bility", but not "sense and responsibility". If caseful
+ matching is in force at the time of the back reference, the
+ case of letters is relevant. For example,
+
+ ((?i)rah)\s+\1
+
+ matches "rah rah" and "RAH RAH", but not "RAH rah", even
+ though the original capturing subpattern is matched case-
+ lessly.
+
+ There may be more than one back reference to the same sub-
+ pattern. If a subpattern has not actually been used in a
+ particular match, any back references to it always fail. For
+ example, the pattern
+
+ (a|(bc))\2
+
+ always fails if it starts to match "a" rather than "bc".
+ Because there may be up to 99 back references, all digits
+ following the backslash are taken as part of a potential
+ back reference number. If the pattern continues with a digit
+ character, some delimiter must be used to terminate the back
+ reference. If the PCRE_EXTENDED option is set, this can be
+ whitespace. Otherwise an empty comment can be used.
+
+ A back reference that occurs inside the parentheses to which
+ it refers fails when the subpattern is first used, so, for
+ example, (a\1) never matches. However, such references can
+ be useful inside repeated subpatterns. For example, the pat-
+ tern
+
+ (a|b\1)+
+
+ matches any number of "a"s and also "aba", "ababbaa" etc. At
+ each iteration of the subpattern, the back reference matches
+ the character string corresponding to the previous
+ iteration. In order for this to work, the pattern must be
+ such that the first iteration does not need to match the
+ back reference. This can be done using alternation, as in
+ the example above, or by a quantifier with a minimum of
+ zero.
+
+
+
+ASSERTIONS
+ An assertion is a test on the characters following or
+ preceding the current matching point that does not actually
+ consume any characters. The simple assertions coded as \b,
+ \B, \A, \Z, \z, ^ and $ are described above. More compli-
+ cated assertions are coded as subpatterns. There are two
+ kinds: those that look ahead of the current position in the
+ subject string, and those that look behind it.
+
+ An assertion subpattern is matched in the normal way, except
+ that it does not cause the current matching position to be
+ changed. Lookahead assertions start with (?= for positive
+ assertions and (?! for negative assertions. For example,
+
+ \w+(?=;)
+
+ matches a word followed by a semicolon, but does not include
+ the semicolon in the match, and
+
+ foo(?!bar)
+
+ matches any occurrence of "foo" that is not followed by
+ "bar". Note that the apparently similar pattern
+
+ (?!foo)bar
+
+ does not find an occurrence of "bar" that is preceded by
+ something other than "foo"; it finds any occurrence of "bar"
+ whatsoever, because the assertion (?!foo) is always true
+ when the next three characters are "bar". A lookbehind
+ assertion is needed to achieve this effect.
+
+ Lookbehind assertions start with (?<= for positive asser-
+ tions and (?<! for negative assertions. For example,
+
+ (?<!foo)bar
+
+ does find an occurrence of "bar" that is not preceded by
+ "foo". The contents of a lookbehind assertion are restricted
+ such that all the strings it matches must have a fixed
+ length. However, if there are several alternatives, they do
+ not all have to have the same fixed length. Thus
+
+ (?<=bullock|donkey)
+
+ is permitted, but
+
+ (?<!dogs?|cats?)
+
+ causes an error at compile time. Branches that match dif-
+ ferent length strings are permitted only at the top level of
+ a lookbehind assertion. This is an extension compared with
+ Perl 5.005, which requires all branches to match the same
+ length of string. An assertion such as
+
+ (?<=ab(c|de))
+
+ is not permitted, because its single top-level branch can
+ match two different lengths, but it is acceptable if rewrit-
+ ten to use two top-level branches:
+
+ (?<=abc|abde)
+
+ The implementation of lookbehind assertions is, for each
+ alternative, to temporarily move the current position back
+ by the fixed width and then try to match. If there are
+ insufficient characters before the current position, the
+ match is deemed to fail. Lookbehinds in conjunction with
+ once-only subpatterns can be particularly useful for match-
+ ing at the ends of strings; an example is given at the end
+ of the section on once-only subpatterns.
+
+ Several assertions (of any sort) may occur in succession.
+ For example,
+
+ (?<=\d{3})(?<!999)foo
+
+ matches "foo" preceded by three digits that are not "999".
+ Notice that each of the assertions is applied independently
+ at the same point in the subject string. First there is a
+ check that the previous three characters are all digits, and
+ then there is a check that the same three characters are not
+ "999". This pattern does not match "foo" preceded by six
+ characters, the first of which are digits and the last three
+ of which are not "999". For example, it doesn't match
+ "123abcfoo". A pattern to do that is
+
+ (?<=\d{3}...)(?<!999)foo
+
+ This time the first assertion looks at the preceding six
+ characters, checking that the first three are digits, and
+ then the second assertion checks that the preceding three
+ characters are not "999".
+
+ Assertions can be nested in any combination. For example,
+
+ (?<=(?<!foo)bar)baz
+
+ matches an occurrence of "baz" that is preceded by "bar"
+ which in turn is not preceded by "foo", while
+
+ (?<=\d{3}(?!999)...)foo
+
+ is another pattern which matches "foo" preceded by three
+ digits and any three characters that are not "999".
+
+ Assertion subpatterns are not capturing subpatterns, and may
+ not be repeated, because it makes no sense to assert the
+ same thing several times. If any kind of assertion contains
+ capturing subpatterns within it, these are counted for the
+ purposes of numbering the capturing subpatterns in the whole
+ pattern. However, substring capturing is carried out only
+ for positive assertions, because it does not make sense for
+ negative assertions.
+
+ Assertions count towards the maximum of 200 parenthesized
+ subpatterns.
+
+
+
+ONCE-ONLY SUBPATTERNS
+ With both maximizing and minimizing repetition, failure of
+ what follows normally causes the repeated item to be re-
+ evaluated to see if a different number of repeats allows the
+ rest of the pattern to match. Sometimes it is useful to
+ prevent this, either to change the nature of the match, or
+ to cause it fail earlier than it otherwise might, when the
+ author of the pattern knows there is no point in carrying
+ on.
+
+ Consider, for example, the pattern \d+foo when applied to
+ the subject line
+
+ 123456bar
+
+ After matching all 6 digits and then failing to match "foo",
+ the normal action of the matcher is to try again with only 5
+ digits matching the \d+ item, and then with 4, and so on,
+ before ultimately failing. Once-only subpatterns provide the
+ means for specifying that once a portion of the pattern has
+ matched, it is not to be re-evaluated in this way, so the
+ matcher would give up immediately on failing to match "foo"
+ the first time. The notation is another kind of special
+ parenthesis, starting with (?> as in this example:
+
+ (?>\d+)bar
+
+ This kind of parenthesis "locks up" the part of the pattern
+ it contains once it has matched, and a failure further into
+ the pattern is prevented from backtracking into it.
+ Backtracking past it to previous items, however, works as
+ normal.
+
+ An alternative description is that a subpattern of this type
+ matches the string of characters that an identical stan-
+ dalone pattern would match, if anchored at the current point
+ in the subject string.
+
+ Once-only subpatterns are not capturing subpatterns. Simple
+ cases such as the above example can be thought of as a max-
+ imizing repeat that must swallow everything it can. So,
+ while both \d+ and \d+? are prepared to adjust the number of
+ digits they match in order to make the rest of the pattern
+ match, (?>\d+) can only match an entire sequence of digits.
+
+ This construction can of course contain arbitrarily compli-
+ cated subpatterns, and it can be nested.
+
+ Once-only subpatterns can be used in conjunction with look-
+ behind assertions to specify efficient matching at the end
+ of the subject string. Consider a simple pattern such as
+
+ abcd$
+
+ when applied to a long string which does not match. Because
+ matching proceeds from left to right, PCRE will look for
+ each "a" in the subject and then see if what follows matches
+ the rest of the pattern. If the pattern is specified as
+
+ ^.*abcd$
+
+ the initial .* matches the entire string at first, but when
+ this fails (because there is no following "a"), it back-
+ tracks to match all but the last character, then all but the
+ last two characters, and so on. Once again the search for
+ "a" covers the entire string, from right to left, so we are
+ no better off. However, if the pattern is written as
+
+ ^(?>.*)(?<=abcd)
+
+ there can be no backtracking for the .* item; it can match
+ only the entire string. The subsequent lookbehind assertion
+ does a single test on the last four characters. If it fails,
+ the match fails immediately. For long strings, this approach
+ makes a significant difference to the processing time.
+
+ When a pattern contains an unlimited repeat inside a subpat-
+ tern that can itself be repeated an unlimited number of
+ times, the use of a once-only subpattern is the only way to
+ avoid some failing matches taking a very long time indeed.
+ The pattern
+
+ (\D+|<\d+>)*[!?]
+
+ matches an unlimited number of substrings that either con-
+ sist of non-digits, or digits enclosed in <>, followed by
+ either ! or ?. When it matches, it runs quickly. However, if
+ it is applied to
+
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+
+ it takes a long time before reporting failure. This is
+ because the string can be divided between the two repeats in
+ a large number of ways, and all have to be tried. (The exam-
+ ple used [!?] rather than a single character at the end,
+ because both PCRE and Perl have an optimization that allows
+ for fast failure when a single character is used. They
+ remember the last single character that is required for a
+ match, and fail early if it is not present in the string.)
+ If the pattern is changed to
+
+ ((?>\D+)|<\d+>)*[!?]
+
+ sequences of non-digits cannot be broken, and failure hap-
+ pens quickly.
+
+
+
+CONDITIONAL SUBPATTERNS
+ It is possible to cause the matching process to obey a sub-
+ pattern conditionally or to choose between two alternative
+ subpatterns, depending on the result of an assertion, or
+ whether a previous capturing subpattern matched or not. The
+ two possible forms of conditional subpattern are
+
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+
+ If the condition is satisfied, the yes-pattern is used; oth-
+ erwise the no-pattern (if present) is used. If there are
+ more than two alternatives in the subpattern, a compile-time
+ error occurs.
+
+ There are two kinds of condition. If the text between the
+ parentheses consists of a sequence of digits, the condition
+ is satisfied if the capturing subpattern of that number has
+ previously matched. The number must be greater than zero.
+ Consider the following pattern, which contains non-
+ significant white space to make it more readable (assume the
+ PCRE_EXTENDED option) and to divide it into three parts for
+ ease of discussion:
+
+ ( \( )? [^()]+ (?(1) \) )
+
+ The first part matches an optional opening parenthesis, and
+ if that character is present, sets it as the first captured
+ substring. The second part matches one or more characters
+ that are not parentheses. The third part is a conditional
+ subpattern that tests whether the first set of parentheses
+ matched or not. If they did, that is, if subject started
+ with an opening parenthesis, the condition is true, and so
+ the yes-pattern is executed and a closing parenthesis is
+ required. Otherwise, since no-pattern is not present, the
+ subpattern matches nothing. In other words, this pattern
+ matches a sequence of non-parentheses, optionally enclosed
+ in parentheses.
+
+ If the condition is not a sequence of digits, it must be an
+ assertion. This may be a positive or negative lookahead or
+ lookbehind assertion. Consider this pattern, again contain-
+ ing non-significant white space, and with the two alterna-
+ tives on the second line:
+
+ (?(?=[^a-z]*[a-z])
+ \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} )
+
+ The condition is a positive lookahead assertion that matches
+ an optional sequence of non-letters followed by a letter. In
+ other words, it tests for the presence of at least one
+ letter in the subject. If a letter is found, the subject is
+ matched against the first alternative; otherwise it is
+ matched against the second. This pattern matches strings in
+ one of the two forms dd-aaa-dd or dd-dd-dd, where aaa are
+ letters and dd are digits.
+
+
+
+COMMENTS
+ The sequence (?# marks the start of a comment which contin-
+ ues up to the next closing parenthesis. Nested parentheses
+ are not permitted. The characters that make up a comment
+ play no part in the pattern matching at all.
+
+ If the PCRE_EXTENDED option is set, an unescaped # character
+ outside a character class introduces a comment that contin-
+ ues up to the next newline character in the pattern.
+
+
+
+RECURSIVE PATTERNS
+ Consider the problem of matching a string in parentheses,
+ allowing for unlimited nested parentheses. Without the use
+ of recursion, the best that can be done is to use a pattern
+ that matches up to some fixed depth of nesting. It is not
+ possible to handle an arbitrary nesting depth. Perl 5.6 has
+ provided an experimental facility that allows regular
+ expressions to recurse (amongst other things). It does this
+ by interpolating Perl code in the expression at run time,
+ and the code can refer to the expression itself. A Perl pat-
+ tern to solve the parentheses problem can be created like
+ this:
+
+ $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+
+ The (?p{...}) item interpolates Perl code at run time, and
+ in this case refers recursively to the pattern in which it
+ appears. Obviously, PCRE cannot support the interpolation of
+ Perl code. Instead, the special item (?R) is provided for
+ the specific case of recursion. This PCRE pattern solves the
+ parentheses problem (assume the PCRE_EXTENDED option is set
+ so that white space is ignored):
+
+ \( ( (?>[^()]+) | (?R) )* \)
+
+ First it matches an opening parenthesis. Then it matches any
+ number of substrings which can either be a sequence of non-
+ parentheses, or a recursive match of the pattern itself
+ (i.e. a correctly parenthesized substring). Finally there is
+ a closing parenthesis.
+
+ This particular example pattern contains nested unlimited
+ repeats, and so the use of a once-only subpattern for match-
+ ing strings of non-parentheses is important when applying
+ the pattern to strings that do not match. For example, when
+ it is applied to
+
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+
+ it yields "no match" quickly. However, if a once-only sub-
+ pattern is not used, the match runs for a very long time
+ indeed because there are so many different ways the + and *
+ repeats can carve up the subject, and all have to be tested
+ before failure can be reported.
+
+ The values set for any capturing subpatterns are those from
+ the outermost level of the recursion at which the subpattern
+ value is set. If the pattern above is matched against
+
+ (ab(cd)ef)
+
+ the value for the capturing parentheses is "ef", which is
+ the last value taken on at the top level. If additional
+ parentheses are added, giving
+
+ \( ( ( (?>[^()]+) | (?R) )* ) \)
+ ^ ^
+ ^ ^ the string they capture is
+ "ab(cd)ef", the contents of the top level parentheses. If
+ there are more than 15 capturing parentheses in a pattern,
+ PCRE has to obtain extra memory to store data during a
+ recursion, which it does by using pcre_malloc, freeing it
+ via pcre_free afterwards. If no memory can be obtained, it
+ saves data for the first 15 capturing parentheses only, as
+ there is no way to give an out-of-memory error from within a
+ recursion.
+
+
+
+PERFORMANCE
+ Certain items that may appear in patterns are more efficient
+ than others. It is more efficient to use a character class
+ like [aeiou] than a set of alternatives such as (a|e|i|o|u).
+ In general, the simplest construction that provides the
+ required behaviour is usually the most efficient. Jeffrey
+ Friedl's book contains a lot of discussion about optimizing
+ regular expressions for efficient performance.
+
+ When a pattern begins with .* and the PCRE_DOTALL option is
+ set, the pattern is implicitly anchored by PCRE, since it
+ can match only at the start of a subject string. However, if
+ PCRE_DOTALL is not set, PCRE cannot make this optimization,
+ because the . metacharacter does not then match a newline,
+ and if the subject string contains newlines, the pattern may
+ match from the character immediately following one of them
+ instead of from the very start. For example, the pattern
+
+ (.*) second
+
+ matches the subject "first\nand second" (where \n stands for
+ a newline character) with the first captured substring being
+ "and". In order to do this, PCRE has to retry the match
+ starting after every newline in the subject.
+
+ If you are using such a pattern with subject strings that do
+ not contain newlines, the best performance is obtained by
+ setting PCRE_DOTALL, or starting the pattern with ^.* to
+ indicate explicit anchoring. That saves PCRE from having to
+ scan along the subject looking for a newline to restart at.
+
+ Beware of patterns that contain nested indefinite repeats.
+ These can take a long time to run when applied to a string
+ that does not match. Consider the pattern fragment
+
+ (a+)*
+
+ This can match "aaaa" in 33 different ways, and this number
+ increases very rapidly as the string gets longer. (The *
+ repeat can match 0, 1, 2, 3, or 4 times, and for each of
+ those cases other than 0, the + repeats can match different
+ numbers of times.) When the remainder of the pattern is such
+ that the entire match is going to fail, PCRE has in princi-
+ ple to try every possible variation, and this can take an
+ extremely long time.
+
+ An optimization catches some of the more simple cases such
+ as
+
+ (a+)*b
+
+ where a literal character follows. Before embarking on the
+ standard matching procedure, PCRE checks that there is a "b"
+ later in the subject string, and if there is not, it fails
+ the match immediately. However, when there is no following
+ literal this optimization cannot be used. You can see the
+ difference by comparing the behaviour of
+
+ (a+)*\d
+
+ with the pattern above. The former gives a failure almost
+ instantly when applied to a whole line of "a" characters,
+ whereas the latter takes an appreciable time with strings
+ longer than about 20 characters.
+
+
+
+UTF-8 SUPPORT
+ Starting at release 3.3, PCRE has some support for character
+ strings encoded in the UTF-8 format. This is incomplete, and
+ is regarded as experimental. In order to use it, you must
+ configure PCRE to include UTF-8 support in the code, and, in
+ addition, you must call pcre_compile() with the PCRE_UTF8
+ option flag. When you do this, both the pattern and any sub-
+ ject strings that are matched against it are treated as
+ UTF-8 strings instead of just strings of bytes, but only in
+ the cases that are mentioned below.
+
+ If you compile PCRE with UTF-8 support, but do not use it at
+ run time, the library will be a bit bigger, but the addi-
+ tional run time overhead is limited to testing the PCRE_UTF8
+ flag in several places, so should not be very large.
+
+ PCRE assumes that the strings it is given contain valid
+ UTF-8 codes. It does not diagnose invalid UTF-8 strings. If
+ you pass invalid UTF-8 strings to PCRE, the results are
+ undefined.
+
+ Running with PCRE_UTF8 set causes these changes in the way
+ PCRE works:
+
+ 1. In a pattern, the escape sequence \x{...}, where the con-
+ tents of the braces is a string of hexadecimal digits, is
+ interpreted as a UTF-8 character whose code number is the
+ given hexadecimal number, for example: \x{1234}. This
+ inserts from one to six literal bytes into the pattern,
+ using the UTF-8 encoding. If a non-hexadecimal digit appears
+ between the braces, the item is not recognized.
+
+ 2. The original hexadecimal escape sequence, \xhh, generates
+ a two-byte UTF-8 character if its value is greater than 127.
+
+ 3. Repeat quantifiers are NOT correctly handled if they fol-
+ low a multibyte character. For example, \x{100}* and \xc3+
+ do not work. If you want to repeat such characters, you must
+ enclose them in non-capturing parentheses, for example
+ (?:\x{100}), at present.
+
+ 4. The dot metacharacter matches one UTF-8 character instead
+ of a single byte.
+
+ 5. Unlike literal UTF-8 characters, the dot metacharacter
+ followed by a repeat quantifier does operate correctly on
+ UTF-8 characters instead of single bytes.
+
+ 4. Although the \x{...} escape is permitted in a character
+ class, characters whose values are greater than 255 cannot
+ be included in a class.
+
+ 5. A class is matched against a UTF-8 character instead of
+ just a single byte, but it can match only characters whose
+ values are less than 256. Characters with greater values
+ always fail to match a class.
+
+ 6. Repeated classes work correctly on multiple characters.
+
+ 7. Classes containing just a single character whose value is
+ greater than 127 (but less than 256), for example, [\x80] or
+ [^\x{93}], do not work because these are optimized into sin-
+ gle byte matches. In the first case, of course, the class
+ brackets are just redundant.
+
+ 8. Lookbehind assertions move backwards in the subject by a
+ fixed number of characters instead of a fixed number of
+ bytes. Simple cases have been tested to work correctly, but
+ there may be hidden gotchas herein.
+
+ 9. The character types such as \d and \w do not work
+ correctly with UTF-8 characters. They continue to test a
+ single byte.
+
+ 10. Anything not explicitly mentioned here continues to work
+ in bytes rather than in characters.
+
+ The following UTF-8 features of Perl 5.6 are not imple-
+ mented:
+ 1. The escape sequence \C to match a single byte.
+
+ 2. The use of Unicode tables and properties and escapes \p,
+ \P, and \X.

+.TH PCREGREP 1
+.SH NAME
+pcregrep - a grep with Perl-compatible regular expressions.
+.SH SYNOPSIS
+.B pcregrep [-Vchilnsvx] pattern [file] ...
+
+
+.SH DESCRIPTION
+\fBpcregrep\fR searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+\fBpcre(3)\fR for a full description of syntax and semantics.
+
+If no files are specified, \fBpcregrep\fR reads the standard input. By default,
+each line that matches the pattern is copied to the standard output, and if
+there is more than one file, the file name is printed before each line of
+output. However, there are options that can change how \fBpcregrep\fR behaves.
+
+Lines are limited to BUFSIZ characters. BUFSIZ is defined in \fB<stdio.h>\fR.
+The newline character is removed from the end of each line before it is matched
+against the pattern.
+
+
+.SH OPTIONS
+.TP 10
+\fB-V\fR
+Write the version number of the PCRE library being used to the standard error
+stream.

+Suppress printing of filenames when searching multiple files.
+.TP
+\fB-i\fR

+
+
+SYNOPSIS
+ pcregrep [-Vchilnsvx] pattern [file] ...
+
+
+
+DESCRIPTION
+ pcregrep searches files for character patterns, in the same
+ way as other grep commands do, but it uses the PCRE regular
+ expression library to support patterns that are compatible
+ with the regular expressions of Perl 5. See pcre(3) for a
+ full description of syntax and semantics.
+
+ If no files are specified, pcregrep reads the standard
+ input. By default, each line that matches the pattern is
+ copied to the standard output, and if there is more than one
+ file, the file name is printed before each line of output.
+ However, there are options that can change how pcregrep
+ behaves.
+
+ Lines are limited to BUFSIZ characters. BUFSIZ is defined in
+ <stdio.h>. The newline character is removed from the end of
+ each line before it is matched against the pattern.
+
+
+
+OPTIONS
+ -V Write the version number of the PCRE library being
+ used to the standard error stream.
+
+ -c Do not print individual lines; instead just print
+ a count of the number of lines that would other-
+ wise have been printed. If several files are
+ given, a count is printed for each of them.
+
+ -h Suppress printing of filenames when searching mul-
+ tiple files.
+
+ -i Ignore upper/lower case distinctions during com-
+ parisons.

+ print the names of the files containing lines that
+ would have been printed. Each file name is printed
+ once, on a separate line.
+
+ -n Precede each line by its line number in the file.
+
+ -s Work silently, that is, display nothing except

+
+
+.SH DESCRIPTION
+This set of functions provides a POSIX-style API to the PCRE regular expression
+package. See the \fBpcre\fR documentation for a description of the native API,
+which contains additional functionality.
+
+The functions described here are just wrapper functions that ultimately call
+the native API. Their prototypes are defined in the \fBpcreposix.h\fR header
+file, and on Unix systems the library itself is called \fBpcreposix.a\fR, so
+can be accessed by adding \fB-lpcreposix\fR to the command for linking an
+application which uses them. Because the POSIX functions call the native ones,
+it is also necessary to add \fR-lpcre\fR.
+
+I have implemented only those option bits that can be reasonably mapped to PCRE
+native options. In addition, the options REG_EXTENDED and REG_NOSUB are defined
+with the value zero. They have no effect, but since programs that are written
+to the POSIX interface often use them, this makes it easier to slot in PCRE as
+a replacement library. Other POSIX options are not even defined.
+
+When PCRE is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE options, as
+described below.
+
+The header for these functions is supplied as \fBpcreposix.h\fR to avoid any
+potential clash with other POSIX libraries. It can, of course, be renamed or
+aliased as \fBregex.h\fR, which is the "correct" name. It provides two
+structure types, \fIregex_t\fR for compiled internal forms, and
+\fIregmatch_t\fR for returning captured substrings. It also defines some
+constants whose names start with "REG_"; these are used for setting options and
+identifying error codes.
+
+
+.SH COMPILING A PATTERN
+
+The function \fBregcomp()\fR is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument \fIpattern\fR. The \fIpreg\fR argument is a pointer
+to a regex_t structure which is used as a base for storing information about
+the compiled expression.
+
+The argument \fIcflags\fR is either zero, or contains one or more of the bits
+defined by the following macros:
+
+ REG_ICASE
+
+The PCRE_CASELESS option is set when the expression is passed for compilation
+to the native function.
+
+ REG_NEWLINE
+
+The PCRE_MULTILINE option is set when the expression is passed for compilation
+to the native function.
+
+In the absence of these flags, no options are passed to the native function.
+This means the the regex is compiled with PCRE default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE_MULTILINE has only
+\fIsome\fR of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by . (they aren't) or a negative class such as [^a] (they
+are).
+
+The yield of \fBregcomp()\fR is zero on success, and non-zero otherwise. The
+\fIpreg\fR structure is filled in on success, and one member of the structure
+is publicized: \fIre_nsub\fR contains the number of capturing subpatterns in
+the regular expression. Various error codes are defined in the header file.
+
+
+.SH MATCHING A PATTERN
+The function \fBregexec()\fR is called to match a pre-compiled pattern
+\fIpreg\fR against a given \fIstring\fR, which is terminated by a zero byte,
+subject to the options in \fIeflags\fR. These can be:
+
+ REG_NOTBOL
+
+The PCRE_NOTBOL option is set when calling the underlying PCRE matching
+function.
+
+ REG_NOTEOL
+
+The PCRE_NOTEOL option is set when calling the underlying PCRE matching
+function.
+
+The portion of the string that was matched, and also any captured substrings,
+are returned via the \fIpmatch\fR argument, which points to an array of
+\fInmatch\fR structures of type \fIregmatch_t\fR, containing the members
+\fIrm_so\fR and \fIrm_eo\fR. These contain the offset to the first character of
+each substring and the offset to the first character after the end of each
+substring, respectively. The 0th element of the vector relates to the entire
+portion of \fIstring\fR that was matched; subsequent elements relate to the
+capturing subpatterns of the regular expression. Unused entries in the array
+have both structure members set to -1.
+
+A successful match yields a zero return; various error codes are defined in the
+header file, of which REG_NOMATCH is the "expected" failure code.
+
+
+.SH ERROR MESSAGES
+The \fBregerror()\fR function maps a non-zero errorcode from either
+\fBregcomp\fR or \fBregexec\fR to a printable message. If \fIpreg\fR is not
+NULL, the error should have arisen from the use of that structure. A message
+terminated by a binary zero is placed in \fIerrbuf\fR. The length of the
+message, including the zero, is limited to \fIerrbuf_size\fR. The yield of the
+function is the size of buffer needed to hold the whole message.
+
+
+.SH STORAGE
+Compiling a regular expression causes memory to be allocated and associated
+with the \fIpreg\fR structure. The function \fBregfree()\fR frees all such
+memory, after which \fIpreg\fR may no longer be used as a compiled expression.

+DESCRIPTION
+ This set of functions provides a POSIX-style API to the PCRE
+ regular expression package. See the pcre documentation for a
+ description of the native API, which contains additional
+ functionality.
+
+ The functions described here are just wrapper functions that
+ ultimately call the native API. Their prototypes are defined
+ in the pcreposix.h header file, and on Unix systems the
+ library itself is called pcreposix.a, so can be accessed by
+ adding -lpcreposix to the command for linking an application
+ which uses them. Because the POSIX functions call the native
+ ones, it is also necessary to add -lpcre.
+
+ I have implemented only those option bits that can be rea-
+ sonably mapped to PCRE native options. In addition, the
+ options REG_EXTENDED and REG_NOSUB are defined with the
+ value zero. They have no effect, but since programs that are
+ written to the POSIX interface often use them, this makes it
+ easier to slot in PCRE as a replacement library. Other POSIX
+ options are not even defined.
+
+ When PCRE is called via these functions, it is only the API
+ that is POSIX-like in style. The syntax and semantics of the
+ regular expressions themselves are still those of Perl, sub-
+ ject to the setting of various PCRE options, as described
+ below.
+
+ The header for these functions is supplied as pcreposix.h to
+ avoid any potential clash with other POSIX libraries. It
+ can, of course, be renamed or aliased as regex.h, which is
+ the "correct" name. It provides two structure types, regex_t
+ for compiled internal forms, and regmatch_t for returning
+ captured substrings. It also defines some constants whose
+ names start with "REG_"; these are used for setting options
+ and identifying error codes.
+
+
+
+COMPILING A PATTERN
+ The function regcomp() is called to compile a pattern into
+ an internal form. The pattern is a C string terminated by a
+ binary zero, and is passed in the argument pattern. The preg
+ argument is a pointer to a regex_t structure which is used
+ as a base for storing information about the compiled expres-
+ sion.
+
+ The argument cflags is either zero, or contains one or more
+ of the bits defined by the following macros:
+
+ REG_ICASE
+
+ The PCRE_CASELESS option is set when the expression is
+ passed for compilation to the native function.
+
+ REG_NEWLINE
+
+ The PCRE_MULTILINE option is set when the expression is
+ passed for compilation to the native function.
+
+ In the absence of these flags, no options are passed to the
+ native function. This means the the regex is compiled with
+ PCRE default semantics. In particular, the way it handles
+ newline characters in the subject string is the Perl way,
+ not the POSIX way. Note that setting PCRE_MULTILINE has only
+ some of the effects specified for REG_NEWLINE. It does not
+ affect the way newlines are matched by . (they aren't) or a
+ negative class such as [^a] (they are).
+
+ The yield of regcomp() is zero on success, and non-zero oth-
+ erwise. The preg structure is filled in on success, and one
+ member of the structure is publicized: re_nsub contains the
+ number of capturing subpatterns in the regular expression.
+ Various error codes are defined in the header file.
+
+
+
+MATCHING A PATTERN
+ The function regexec() is called to match a pre-compiled
+ pattern preg against a given string, which is terminated by
+ a zero byte, subject to the options in eflags. These can be:
+
+ REG_NOTBOL
+
+ The PCRE_NOTBOL option is set when calling the underlying
+ PCRE matching function.
+
+ REG_NOTEOL
+
+ The PCRE_NOTEOL option is set when calling the underlying
+ PCRE matching function.
+
+ The portion of the string that was matched, and also any
+ captured substrings, are returned via the pmatch argument,
+ which points to an array of nmatch structures of type
+ regmatch_t, containing the members rm_so and rm_eo. These
+ contain the offset to the first character of each substring
+ and the offset to the first character after the end of each
+ substring, respectively. The 0th element of the vector
+ relates to the entire portion of string that was matched;
+ subsequent elements relate to the capturing subpatterns of
+ the regular expression. Unused entries in the array have
+ both structure members set to -1.
+
+ A successful match yields a zero return; various error codes
+ are defined in the header file, of which REG_NOMATCH is the
+ "expected" failure code.
+
+
+
+ERROR MESSAGES
+ The regerror() function maps a non-zero errorcode from
+ either regcomp or regexec to a printable message. If preg is
+ not NULL, the error should have arisen from the use of that
+ structure. A message terminated by a binary zero is placed
+ in errbuf. The length of the message, including the zero, is
+ limited to errbuf_size. The yield of the function is the
+ size of buffer needed to hold the whole message.
+
+
+
+STORAGE
+ Compiling a regular expression causes memory to be allocated
+ and associated with the preg structure. The function reg-
+ free() frees all such memory, after which preg may no longer
+ be used as a compiled expression.

+The pcretest program
+--------------------
+
+This program is intended for testing PCRE, but it can also be used for
+experimenting with regular expressions.
+
+If it is given two filename arguments, it reads from the first and writes to
+the second. If it is given only one filename argument, it reads from that file
+and writes to stdout. Otherwise, it reads from stdin and writes to stdout, and
+prompts for each line of input, using "re>" to prompt for regular expressions,
+and "data>" to prompt for data lines.
+
+The program handles any number of sets of input on a single input file. Each
+set starts with a regular expression, and continues with any number of data
+lines to be matched against the pattern. An empty line signals the end of the
+data lines, at which point a new regular expression is read. The regular
+expressions are given enclosed in any non-alphameric delimiters other than
+backslash, for example
+
+ /(a|bc)x+yz/
+
+White space before the initial delimiter is ignored. A regular expression may
+be continued over several input lines, in which case the newline characters are
+included within it. See the test input files in the testdata directory for many
+examples. It is possible to include the delimiter within the pattern by
+escaping it, for example
+
+ /abc\/def/
+
+If you do so, the escape and the delimiter form part of the pattern, but since
+delimiters are always non-alphameric, this does not affect its interpretation.
+If the terminating delimiter is immediately followed by a backslash, for
+example,
+
+ /abc/\
+
+then a backslash is added to the end of the pattern. This is done to provide a
+way of testing the error condition that arises if a pattern finishes with a
+backslash, because
+
+ /abc\/
+
+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcretest to read the next line as a continuation of the regular expression.
+
+
+PATTERN MODIFIERS
+-----------------
+
+The pattern may be followed by i, m, s, or x to set the PCRE_CASELESS,
+PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED options, respectively. For
+example:
+
+ /caseless/i
+
+These modifier letters have the same effect as they do in Perl. There are
+others which set PCRE options that do not correspond to anything in Perl: /A,
+/E, and /X set PCRE_ANCHORED, PCRE_DOLLAR_ENDONLY, and PCRE_EXTRA respectively.
+
+Searching for all possible matches within each subject string can be requested
+by the /g or /G modifier. After finding a match, PCRE is called again to search
+the remainder of the subject string. The difference between /g and /G is that
+the former uses the startoffset argument to pcre_exec() to start searching at
+a new point within the entire string (which is in effect what Perl does),
+whereas the latter passes over a shortened substring. This makes a difference
+to the matching process if the pattern begins with a lookbehind assertion
+(including \b or \B).
+
+If any call to pcre_exec() in a /g or /G sequence matches an empty string, the
+next call is done with the PCRE_NOTEMPTY and PCRE_ANCHORED flags set in order
+to search for another, non-empty, match at the same point. If this second match
+fails, the start offset is advanced by one, and the normal match is retried.
+This imitates the way Perl handles such cases when using the /g modifier or the
+split() function.
+
+There are a number of other modifiers for controlling the way pcretest
+operates.
+
+The /+ modifier requests that as well as outputting the substring that matched
+the entire pattern, pcretest should in addition output the remainder of the
+subject string. This is useful for tests where the subject contains multiple
+copies of the same substring.
+
+The /L modifier must be followed directly by the name of a locale, for example,
+
+ /pattern/Lfr
+
+For this reason, it must be the last modifier letter. The given locale is set,
+pcre_maketables() is called to build a set of character tables for the locale,
+and this is then passed to pcre_compile() when compiling the regular
+expression. Without an /L modifier, NULL is passed as the tables pointer; that
+is, /L applies only to the expression on which it appears.
+
+The /I modifier requests that pcretest output information about the compiled
+expression (whether it is anchored, has a fixed first character, and so on). It
+does this by calling pcre_fullinfo() after compiling an expression, and
+outputting the information it gets back. If the pattern is studied, the results
+of that are also output.
+
+The /D modifier is a PCRE debugging feature, which also assumes /I. It causes
+the internal form of compiled regular expressions to be output after
+compilation.
+
+The /S modifier causes pcre_study() to be called after the expression has been
+compiled, and the results used when the expression is matched.
+
+The /M modifier causes the size of memory block used to hold the compiled
+pattern to be output.
+
+The /P modifier causes pcretest to call PCRE via the POSIX wrapper API rather
+than its native API. When this is done, all other modifiers except /i, /m, and
+/+ are ignored. REG_ICASE is set if /i is present, and REG_NEWLINE is set if /m
+is present. The wrapper functions force PCRE_DOLLAR_ENDONLY always, and
+PCRE_DOTALL unless REG_NEWLINE is set.
+
+The /8 modifier causes pcretest to call PCRE with the PCRE_UTF8 option set.
+This turns on the (currently incomplete) support for UTF-8 character handling
+in PCRE, provided that it was compiled with this support enabled. This modifier
+also causes any non-printing characters in output strings to be printed using
+the \x{hh...} notation if they are valid UTF-8 sequences.
+
+
+DATA LINES
+----------
+
+Before each data line is passed to pcre_exec(), leading and trailing whitespace
+is removed, and it is then scanned for \ escapes. The following are recognized:
+
+ \a alarm (= BEL)
+ \b backspace
+ \e escape
+ \f formfeed
+ \n newline
+ \r carriage return
+ \t tab
+ \v vertical tab
+ \nnn octal character (up to 3 octal digits)
+ \xhh hexadecimal character (up to 2 hex digits)
+ \x{hh...} hexadecimal UTF-8 character
+
+ \A pass the PCRE_ANCHORED option to pcre_exec()
+ \B pass the PCRE_NOTBOL option to pcre_exec()
+ \Cdd call pcre_copy_substring() for substring dd after a successful
+ match (any decimal number less than 32)
+ \Gdd call pcre_get_substring() for substring dd after a successful
+ match (any decimal number less than 32)
+ \L call pcre_get_substringlist() after a successful match
+ \N pass the PCRE_NOTEMPTY option to pcre_exec()
+ \Odd set the size of the output vector passed to pcre_exec() to dd
+ (any number of decimal digits)
+ \Z pass the PCRE_NOTEOL option to pcre_exec()
+
+A backslash followed by anything else just escapes the anything else. If the
+very last character is a backslash, it is ignored. This gives a way of passing
+an empty line as data, since a real empty line terminates the data input.
+
+If /P was present on the regex, causing the POSIX wrapper API to be used, only
+\B, and \Z have any effect, causing REG_NOTBOL and REG_NOTEOL to be passed to
+regexec() respectively.
+
+The use of \x{hh...} to represent UTF-8 characters is not dependent on the use
+of the /8 modifier on the pattern. It is recognized always. There may be any
+number of hexadecimal digits inside the braces. The result is from one to six
+bytes, encoded according to the UTF-8 rules.
+
+
+OUTPUT FROM PCRETEST
+--------------------
+
+When a match succeeds, pcretest outputs the list of captured substrings that
+pcre_exec() returns, starting with number 0 for the string that matched the
+whole pattern. Here is an example of an interactive pcretest run.
+
+ $ pcretest
+ PCRE version 2.06 08-Jun-1999
+
+ re> /^abc(\d+)/
+ data> abc123
+ 0: abc123
+ 1: 123
+ data> xyz
+ No match
+
+If the strings contain any non-printing characters, they are output as \0x
+escapes, or as \x{...} escapes if the /8 modifier was present on the pattern.
+If the pattern has the /+ modifier, then the output for substring 0 is followed
+by the the rest of the subject string, identified by "0+" like this:
+
+ re> /cat/+
+ data> cataract
+ 0: cat
+ 0+ aract
+
+If the pattern has the /g or /G modifier, the results of successive matching
+attempts are output in sequence, like this:
+
+ re> /\Bi(\w\w)/g
+ data> Mississippi
+ 0: iss
+ 1: ss
+ 0: iss
+ 1: ss
+ 0: ipp
+ 1: pp
+
+"No match" is output only if the first match attempt fails.
+
+If any of \C, \G, or \L are present in a data line that is successfully
+matched, the substrings extracted by the convenience functions are output with
+C, G, or L after the string number instead of a colon. This is in addition to
+the normal full list. The string length (that is, the return from the
+extraction function) is given in parentheses after each string for \C and \G.
+
+Note that while patterns can be continued over several lines (a plain ">"
+prompt is used for continuations), data lines may not. However newlines can be
+included in data by means of the \n escape.
+
+
+COMMAND LINE OPTIONS
+--------------------
+
+If the -p option is given to pcretest, it is equivalent to adding /P to each
+regular expression: the POSIX wrapper API is used to call PCRE. None of the
+following flags has any effect in this case.
+
+If the option -d is given to pcretest, it is equivalent to adding /D to each
+regular expression: the internal form is output after compilation.
+
+If the option -i is given to pcretest, it is equivalent to adding /I to each
+regular expression: information about the compiled pattern is given after
+compilation.
+
+If the option -m is given to pcretest, it outputs the size of each compiled
+pattern after it has been compiled. It is equivalent to adding /M to each
+regular expression. For compatibility with earlier versions of pcretest, -s is
+a synonym for -m.
+
+If the -t option is given, each compile, study, and match is run 20000 times
+while being timed, and the resulting time per compile or match is output in
+milliseconds. Do not set -t with -m, because you will then get the size output
+20000 times and the timing will be distorted. If you want to change the number
+of repetitions used for timing, edit the definition of LOOPREPEAT at the top of
+pcretest.c

+The perltest program
+--------------------
+
+The perltest program tests Perl's regular expressions; it has the same
+specification as pcretest, and so can be given identical input, except that
+input patterns can be followed only by Perl's lower case modifiers and /+ (as
+used by pcretest), which is recognized and handled by the program.
+
+The data lines are processed as Perl double-quoted strings, so if they contain
+" \ $ or @ characters, these have to be escaped. For this reason, all such
+characters in testinput1 and testinput3 are escaped so that they can be used
+for perltest as well as for pcretest, and the special upper case modifiers such
+as /A that pcretest recognizes are not used in these files. The output should
+be identical, apart from the initial identifying banner.
+
+For testing UTF-8 features, an alternative form of perltest, called perltest8,
+is supplied. This requires Perl 5.6 or higher. It recognizes the special
+modifier /8 that pcretest uses to invoke UTF-8 functionality. The testinput5
+file can be fed to perltest8.
+
+The testinput2 and testinput4 files are not suitable for feeding to perltest,
+since they do make use of the special upper case modifiers and escapes that
+pcretest uses to test some features of PCRE. The first of these files also
+contains malformed regular expressions, in order to check that PCRE diagnoses
+them correctly. Similarly, testinput6 tests UTF-8 features that do not relate
+to Perl.

+README file for PCRE (Perl-compatible regular expression library)
+-----------------------------------------------------------------
+
+The latest release of PCRE is always available from
+
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-xxx.tar.gz
+
+Please read the NEWS file if you are upgrading from a previous release.
+
+PCRE has its own native API, but a set of "wrapper" functions that are based on
+the POSIX API are also supplied in the library libpcreposix. Note that this
+just provides a POSIX calling interface to PCRE: the regular expressions
+themselves still follow Perl syntax and semantics. The header file
+for the POSIX-style functions is called pcreposix.h. The official POSIX name is
+regex.h, but I didn't want to risk possible problems with existing files of
+that name by distributing it that way. To use it with an existing program that
+uses the POSIX API, it will have to be renamed or pointed at by a link.
+
+
+Building PCRE on a Unix system
+------------------------------
+
+To build PCRE on a Unix system, run the "configure" command in the PCRE
+distribution directory. This is a standard GNU "autoconf" configuration script,
+for which generic instructions are supplied in INSTALL. On many systems just
+running "./configure" is sufficient, but the usual methods of changing standard
+defaults are available. For example,
+
+CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
+
+specifies that the C compiler should be run with the flags '-O2 -Wall' instead
+of the default, and that "make install" should install PCRE under /opt/local
+instead of the default /usr/local.
+
+If you want to make use of the experimential, incomplete support for UTF-8
+character strings in PCRE, you must add --enable-utf8 to the "configure"
+command. Without it, the code for handling UTF-8 is not included in the
+library. (Even when included, it still has to be enabled by an option at run
+time.)
+
+The "configure" script builds four files:
+
+. Makefile is built by copying Makefile.in and making substitutions.
+. config.h is built by copying config.in and making substitutions.
+. pcre-config is built by copying pcre-config.in and making substitutions.
+. RunTest is a script for running tests
+
+Once "configure" has run, you can run "make". It builds two libraries called
+libpcre and libpcreposix, a test program called pcretest, and the pcregrep
+command. You can use "make install" to copy these, and the public header file
+pcre.h, to appropriate live directories on your system, in the normal way.
+
+Running "make install" also installs the command pcre-config, which can be used
+to recall information about the PCRE configuration and installation. For
+example,
+
+ pcre-config --version
+
+prints the version number, and
+
+ pcre-config --libs
+
+outputs information about where the library is installed. This command can be
+included in makefiles for programs that use PCRE, saving the programmer from
+having to remember too many details.
+
+
+Shared libraries on Unix systems
+--------------------------------
+
+The default distribution builds PCRE as two shared libraries. This support is
+new and experimental and may not work on all systems. It relies on the
+"libtool" scripts - these are distributed with PCRE. It should build a
+"libtool" script and use this to compile and link shared libraries, which are
+placed in a subdirectory called .libs. The programs pcretest and pcregrep are
+built to use these uninstalled libraries by means of wrapper scripts. When you
+use "make install" to install shared libraries, pcregrep and pcretest are
+automatically re-built to use the newly installed libraries. However, only
+pcregrep is installed, as pcretest is really just a test program.
+
+To build PCRE using static libraries you must use --disable-shared when
+configuring it. For example
+
+./configure --prefix=/usr/gnu --disable-shared
+
+Then run "make" in the usual way.
+
+
+Building on non-Unix systems
+----------------------------
+
+For a non-Unix system, read the comments in the file NON-UNIX-USE. PCRE has
+been compiled on Windows systems and on Macintoshes, but I don't know the
+details because I don't use those systems. It should be straightforward to
+build PCRE on any system that has a Standard C compiler, because it uses only
+Standard C functions.
+
+
+Testing PCRE
+------------
+
+To test PCRE on a Unix system, run the RunTest script in the pcre directory.
+(This can also be run by "make runtest", "make check", or "make test".) For
+other systems, see the instruction in NON-UNIX-USE.
+
+The script runs the pcretest test program (which is documented in
+doc/pcretest.txt) on each of the testinput files (in the testdata directory) in
+turn, and compares the output with the contents of the corresponding testoutput
+file. A file called testtry is used to hold the output from pcretest. To run
+pcretest on just one of the test files, give its number as an argument to
+RunTest, for example:
+
+ RunTest 3
+
+The first and third test files can also be fed directly into the perltest
+script to check that Perl gives the same results. The third file requires the
+additional features of release 5.005, which is why it is kept separate from the
+main test input, which needs only Perl 5.004. In the long run, when 5.005 (or
+higher) is widespread, these two test files may get amalgamated.
+
+The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(),
+pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error
+detection, and run-time flags that are specific to PCRE, as well as the POSIX
+wrapper API. It also uses the debugging flag to check some of the internals of
+pcre_compile().
+
+If you build PCRE with a locale setting that is not the standard C locale, the
+character tables may be different (see next paragraph). In some cases, this may
+cause failures in the second set of tests. For example, in a locale where the
+isprint() function yields TRUE for characters in the range 128-255, the use of
+[:isascii:] inside a character class defines a different set of characters, and
+this shows up in this test as a difference in the compiled code, which is being
+listed for checking. Where the comparison test output contains [\x00-\x7f] the
+test will contain [\x00-\xff], and similarly in some other cases. This is not a
+bug in PCRE.
+
+The fourth set of tests checks pcre_maketables(), the facility for building a
+set of character tables for a specific locale and using them instead of the
+default tables. The tests make use of the "fr" (French) locale. Before running
+the test, the script checks for the presence of this locale by running the
+"locale" command. If that command fails, or if it doesn't include "fr" in the
+list of available locales, the fourth test cannot be run, and a comment is
+output to say why. If running this test produces instances of the error
+
+ ** Failed to set locale "fr"
+
+in the comparison output, it means that locale is not available on your system,
+despite being listed by "locale". This does not mean that PCRE is broken.
+
+The fifth test checks the experimental, incomplete UTF-8 support. It is not run
+automatically unless PCRE is built with UTF-8 support. This file can be fed
+directly to the perltest8 script, which requires Perl 5.6 or higher. The sixth
+file tests internal UTF-8 features of PCRE that are not relevant to Perl.
+
+
+Character tables
+----------------
+
+PCRE uses four tables for manipulating and identifying characters. The final
+argument of the pcre_compile() function is a pointer to a block of memory
+containing the concatenated tables. A call to pcre_maketables() can be used to
+generate a set of tables in the current locale. If the final argument for
+pcre_compile() is passed as NULL, a set of default tables that is built into
+the binary is used.
+
+The source file called chartables.c contains the default set of tables. This is
+not supplied in the distribution, but is built by the program dftables
+(compiled from dftables.c), which uses the ANSI C character handling functions
+such as isalnum(), isalpha(), isupper(), islower(), etc. to build the table
+sources. This means that the default C locale which is set for your system will
+control the contents of these default tables. You can change the default tables
+by editing chartables.c and then re-building PCRE. If you do this, you should
+probably also edit Makefile to ensure that the file doesn't ever get
+re-generated.
+
+The first two 256-byte tables provide lower casing and case flipping functions,
+respectively. The next table consists of three 32-byte bit maps which identify
+digits, "word" characters, and white space, respectively. These are used when
+building 32-byte bit maps that represent character classes.
+
+The final 256-byte table has bits indicating various character types, as
+follows:
+
+ 1 white space character
+ 2 letter
+ 4 decimal digit
+ 8 hexadecimal digit
+ 16 alphanumeric or '_'
+ 128 regular expression metacharacter or binary zero
+
+You should not alter the set of characters that contain the 128 bit, as that
+will cause PCRE to malfunction.
+
+
+Manifest
+--------
+
+The distribution should contain the following files:
+
+(A) The actual source files of the PCRE library functions and their
+ headers:

+Basic Installation
+==================
+
+ These are generic installation instructions that apply to systems that
+can run the `configure' shell script - Unix systems and any that imitate
+it. They are not specific to PCRE. There are PCRE-specific instructions
+for non-Unix systems in the file NON-UNIX-USE.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+ * is, it mimics Perl's 's' operator. See pcrs(3) for details.
+ *

+ *
+ * Revision 1.28 2007/08/18 14:37:27 fabiankeil
+ * Ditch hex_to_byte() in favour of xtoi().
+ *

+ * #1763173 from Stefan Huehner: s@const static@static const@.
+ *
+ * Revision 1.26 2007/07/01 13:29:54 fabiankeil
+ * Add limited hex notation support for the PCRS
+ * substitution text ('\x7e' = '~'). Closes #1627140.
+ *
+ * Revision 1.25 2007/04/30 15:02:18 fabiankeil
+ * Introduce dynamic pcrs jobs that can resolve variables.
+ *
+ * Revision 1.24 2007/01/05 15:46:12 fabiankeil
+ * Don't use strlen() to calculate the length of
+ * the pcrs substitutes. They don't have to be valid C
+ * strings and getting their length wrong can result in
+ * user-controlled memory corruption.
+ *
+ * Thanks to Felix Gröbert for reporting the problem
+ * and providing the fix [#1627140].
+ *
+ * Revision 1.23 2006/12/29 17:53:05 fabiankeil

+ *
+ * Catch NULL subjects early in pcrs_execute().
+ *
+ * Revision 1.21 2006/07/18 14:48:47 david__schmidt

+ * Revision 1.19.2.3 2003/12/04 12:32:45 oes
+ * Append a trailing nullbyte to result to facilitate string processing
+ *
+ * Revision 1.19.2.2 2002/10/08 16:22:28 oes
+ * Bugfix: Need to check validity of backreferences explicitly,
+ * because when max_matches are reached and matches is expanded,
+ * realloc() does not zero the memory. Fixes Bug # 606227
+ *
+ * Revision 1.19.2.1 2002/08/10 11:23:40 oes

+ * Revision 1.13 2001/09/06 14:05:59 oes
+ * Fixed silly bug
+ *
+ * Revision 1.12 2001/08/18 11:35:00 oes
+ * - Introduced pcrs_strerror()
+ * - made some NULL arguments non-fatal
+ * - added support for \n \r \e \b \t \f \a \0 in substitute
+ * - made quoting adhere to standard rules
+ * - added warning for bad backrefs
+ * - added pcrs_execute_list()
+ * - fixed comments
+ * - bugfix & cosmetics
+ *
+ * Revision 1.11 2001/08/15 15:32:03 oes
+ * - Added support for Perl's special variables $+, $' and $`
+ * - Improved the substitute parser
+ * - Replaced the hard limit for the maximum number of matches

+ * - Cleaned up, renamed and reordered functions,
+ * improved comments
+ * - Removed my_strsep
+ * - Replaced globalflag with a general flags int
+ * that holds PCRS_GLOBAL, PCRS_SUCCESS, and PCRS_TRIVIAL
+ * - Introduced trivial option that will prevent pcrs
+ * from honouring backreferences in the substitute,
+ * which is useful for large substitutes that are
+ * red in from somewhere and saves the pain of escaping
+ * the backrefs
+ * - Introduced convenience function pcrs_free_joblist()
+ * - Split pcrs_make_job() into pcrs_compile(), which still
+ * takes a complete s/// comand as argument and parses it,
+ * and a new function pcrs_make_job, which takes the
+ * three separate components. This should make for a
+ * much friendlier frontend.
+ * - Removed create_pcrs_job() which was useless
+ * - Fixed a bug in pcrs_execute
+ * - Success flag is now handled by pcrs instead of user
+ *
+ * Revision 1.6 2001/06/03 19:12:45 oes

+ * Fixed bug: Empty substitutes now detected
+ *
+ * Revision 1.3 2001/05/25 11:03:55 oes
+ * Added sanity check for NULL jobs to pcrs_exec_substitution
+ *
+ * Revision 1.2 2001/05/22 18:46:04 oes
+ *
+ * Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * Revision 1.1.1.1 2001/05/15 13:59:02 oes
+ * Initial import of version 2.9.3 source tree

+Privoxy is a web proxy with advanced filtering capabilities for
+protecting privacy, filtering web page data, managing cookies,
+controlling access, and removing ads, banners, pop-ups and other
+obnoxious Internet junk. Privoxy has a very flexible configuration and
+can be customized to suit individual needs and tastes. Privoxy has application
+for both stand-alone systems and multi-user networks.
+
+Privoxy is based on the Internet Junkbuster.

+ value we hope to standarize for all distributions. RedHat already

+
+* Mon Sep 25 2000 Stefan Waldherr <stefan(a)waldherr.org>
+- CLF Logging patch by davep(a)cyw.uklinux.net
+- Hal DeVore <haldevore(a)earthling.net> fix akamaitech in blocklist
+
+* Sun Sep 17 2000 Stefan Waldherr <stefan(a)waldherr.org>
+- Steve Kemp skx(a)tardis.ed.ac.uk's javascript popup patch.
+- Markus Breitenbach breitenb(a)rbg.informatik.tu-darmstadt.de supplied
+ numerous fixes and enhancements for Steve's patch.
+- adamlock(a)netscape.com (Adam Lock) in the windows version:
+ - Taskbar activity spinner always spins even when logging is
+ turned off (which is the default) - people who don't
+ like the spinner can turn it off from a menu option.
+ - Taskbar popup menu has a options submenu - people can now
+ open the settings files for cookies, blockers etc.
+ without opening the JB window.
+ - Logging functionality works again
+ - Buffer overflow is fixed - new code uses a bigger buffer
+ and snprintf so it shouldn't overflow anymore.
+- Fixed userid swa, group learning problem while installing.
+ root must build RPM.
+- Added patch by Benjamin Low <ben(a)snrc.uow.edu.au> that prevents JB to
+ core dump when there is no log file.
+- Tweaked SuSE startup with the help of mohataj(a)gmx.net and Doc.B(a)gmx.de.
+- Fixed man page to include imagefile and popupfile.
+- Sanity check for the statistics function added.
+- "Patrick D'Cruze" <pdcruze(a)orac.iinet.net.au>: It seems Microsoft
+ are transitioning Hotmail from FreeBSD/Apache to Windows 2000/IIS.
+ With IIS/5, it appears to omit the trailing \r\n from http header
+ only messages. eg, when I visit http://www.hotmail.com, IIS/5
+ responds with a HTTP 302 redirect header. However, this header
+ message is missing the trailing \r\n. IIS/5 then closes the
+ connection. Junkbuster, unfortunately, discards the header becomes
+ it thinks it is incomplete - and it is. MS have transmitted an
+ incomplete header!
+- Added bug reports and patch submission forms in the docs.
+
+* Mon Mar 20 2000 Stefan Waldherr <stefan(a)waldherr.org>
+ Andrew <anw(a)tirana.freewire.co.uk> extended the JB:
+ Display of statistics of the total number of requests and the number
+ of requests filtered by junkbuster, also the percentage of requests
+ filtered. Suppression of the listing of files on the proxy-args page.
+ All stuff optional and configurable.
+
+* Sun Sep 12 1999 Stefan Waldherr <stefan(a)waldherr.org>
+ Jan Willamowius (jan(a)janhh.shnet.org) fixed a bug in the
+ code which prevented the JB from handling URLs of the form
+ user:password@www.foo.com. Fixed.
+
+* Mon Aug 2 1999 Stefan Waldherr <stefan(a)waldherr.org>
+ Blank images are no longer cached, thanks to a hint from Markus
+ Breitenbach <breitenb(a)rbg.informatik.tu-darmstadt.de>. The user
+ agent is NO longer set by the Junkbuster. Sadly, many sites depend
+ on the correct browser version nowadays. Incorporated many
+ suggestions from Jan "Yenya" Kasprzak <kas(a)fi.muni.cz> for the
+ spec file. Fixed logging problem and since runlevel 2 does not
+ use networking, I replaced /etc/rc.d/rc2.d/S84junkbuster with
+ /etc/rc.d/rc2.d/K09junkbuster thanks to Shaw Walker
+ <walker(a)netgate.net>. You should now be able to build this RPM as
+ a non-root user (mathias(a)weidner.sem.lipsia.de)
+
+* Sun Jan 31 1999 Stefan Waldherr <stefan(a)waldherr.org>
+ %%{_localstatedir}/log/junkbuster set to nobody. Added /etc/junkbuster/imagelist
+ to allow more sophisticated matching of blocked images. Logrotate
+ logfile. Added files for auto-updating the blocklist et al.
+
+* Wed Dec 16 1998 Stefan Waldherr <stefan(a)waldherr.org>
+ Configure blank version via config file. No separate blank
+ version anymore. Added Roland's <roland(a)spinnaker.rhein.de>
+ patch to show a logo instead of a blank area. Added a suggestion
+ from Alex <alex(a)cocoa.demon.co.uk>: %%{_localstatedir}/lock/subsys/junkbuster.
+ More regexps in the blocklist. Prepared the forwardfile for
+ squid. Extended image regexp with help from gabriel
+ <somlo(a)CS.ColoState.EDU>.
+
+* Thu Nov 19 1998 Stefan Waldherr <stefan(a)waldherr.org>
+ All RPMs now identify themselves in the show-proxy-args page.
+ Released Windoze version. Run junkbuster as nobody instead of
+ root.
+
+* Fri Oct 30 1998 Stefan Waldherr <stefan(a)waldherr.org>
+ Newest version. First release (hence the little version number
+ mixture -- 2.0.2-0 instead of 2.0-7). This version tightens
+ security over 2.0.1; some multi-user sites will need to change
+ the listen-address in the configuration file. The blank version of
+ the Internet Junkbuster has a more sophisticated way of replacing
+ images. All RPMs identify themselves in the show-proxy-args page.
+
+* Thu Sep 23 1998 Stefan Waldherr <stefan(a)waldherr.org>
+ Modified the blocking feature, so that only GIFs and JPEGs are
+ blocked and replaced but not HTML pages. Thanks to
+ "Gerd Flender" <plgerd(a)informatik.uni-siegen.de> for this nice
+ idea. Added numerous stuff to the blocklist. Keep patches in
+ seperate files and no longer in diffs (easier to maintain).
+
+* Tue Jun 16 1998 Stefan Waldherr <swa(a)cs.cmu.edu>
+ Moved config files to /etc/junkbuster directory, moved man page,
+ added BuildRoot directive (Thanks to Alexey Nogin <ayn2(a)cornell.edu>)
+ Made new version junkbuster-raw (which is only a stripped version of
+ the junkuster rpm, i.e. without my blocklist, etc.)
+
+* Tue Jun 16 1998 (2.0-1)
+ Uhm, not that much. Just a new junkbuster version that
+ fixes a couple of bugs ... and of course a bigger
+ blocklist with the unique Now-less-ads-than-ever(SM)
+ feature.
+ Oh, one thing: I changed the default user agent to Linux -- no
+ need anymore to support Apple.
+
+* Tue Jun 16 1998 (2.0-0)
+ Now-less-ads-than-ever (SM)
+ compiled with gcc instead of cc
+ compiled with -O3, thus it should be a little faster
+ show-proxy-args now works
+ /etc/junkbuster.init wasn't necessary
+
+* Tue Jun 16 1998 (1.4)
+ some more config files were put into /etc
+ The junkbuster-blank rpm returns a 1x1 pixel image, that gets
+ displayed by Netscape instead of the blocked image.
+ Read http://www.waldherr.org/junkbuster/ for
+ further info.
+
+* Tue Jun 16 1998 (1.3)
+ The program has been moved to /usr/sbin (from /usr/local/bin)
+ Init- and stopscripts (/etc/rc.d/rc*) have been added so
+ that the junkbuster starts automatically during bootup.
+ The /etc/blocklist file is much more sophisticated. Theoretically
+ one should e.g. browse all major US and German newspapers without
+ seeing one annoying ad.
+ junkbuster.init was modified. It now starts junkbuster with an
+ additional "-r @" flag.

+.SH NAME
+privoxy \- Privacy Enhancing Proxy
+.SH SYNOPSIS
+
+\fBprivoxy\fR [\fB\-\-help\fR ] [\fB\-\-version\fR ] [\fB\-\-no-daemon\fR ] [\fB\-\-pidfile \fIpidfile\fB\fR ] [\fB\-\-user \fIuser[.group]\fB\fR ] [\fB\-\-chroot\fR ] [\fB\-\-pre-chroot-nslookup \fIhostname\fB\fR ] [\fB\fIconfigfile\fB\fR ]
+
+.SH "OPTIONS"
+.PP
+\fBPrivoxy\fR may be invoked with the following command line
+options:
+.TP
+\fB\-\-help\fR
+Print brief usage info and exit.
+.TP
+\fB\-\-version\fR
+Print version info and exit.
+.TP
+\fB\-\-no-daemon\fR
+Don't become a daemon, i.e. don't fork and become process group
+leader, don't detach from controlling tty, and do all logging there.
+.TP
+\fB\-\-pidfile \fIpidfile\fB\fR
+On startup, write the process ID to \fIpidfile\fR.
+Delete the \fIpidfile\fR on exit.
+Failure to create or delete the \fIpidfile\fR
+is non-fatal. If no \fB\-\-pidfile\fR option is given, no PID file will be used.
+.TP
+\fB\-\-user \fIuser[.group]\fB\fR
+After (optionally) writing the PID file, assume the user ID of
+\fIuser\fR and the GID of
+\fIgroup\fR, or, if the optional
+\fIgroup\fR was not given, the default group of
+\fIuser\fR. Exit if the privileges are not
+sufficient to do so.
+.TP
+\fB\-\-chroot\fR
+Before changing to the user ID given in the \-\-user option, chroot to
+that user's home directory, i.e. make the kernel pretend to the
+\fBPrivoxy\fR process that the directory tree starts
+there. If set up carefully, this can limit the impact of possible
+vulnerabilities in \fBPrivoxy\fR to the files contained in
+that hierarchy.
+.TP
+\fB\-\-pre-chroot-nslookup \fIhostname\fB\fR
+Initialize the resolver library using \fIhostname\fR
+before chroot'ing. On some systems this reduces the number of files
+that must be copied into the chroot tree.
+.PP
+If the \fIconfigfile\fR is not specified on the command line,
+\fBPrivoxy\fR will look for a file named
+\fIconfig\fR in the current directory. If no
+\fIconfigfile\fR is found, \fBPrivoxy\fR will
+fail to start.
+.SH "DESCRIPTION"
+.PP
+Privoxy is a non-caching web proxy with advanced filtering capabilities
+for enhancing privacy, modifying web page data and HTTP headers, controlling
+access, and removing ads and other obnoxious Internet junk. Privoxy has a
+flexible configuration and can be customized to suit individual needs and tastes.
+It has application for both stand-alone systems and multi-user networks.
+.PP
+Privoxy is Free Software and licensed under the GPL2.
+.SH "INSTALLATION AND USAGE"
+.PP
+Browsers can either be individually configured to use
+\fBPrivoxy\fR as a HTTP proxy (recommended),
+or \fBPrivoxy\fR can be combined with a packet
+filter to build an intercepting proxy
+(see \fIconfig\fR). The default setting is for
+localhost, on port 8118 (configurable in the main config file). To set the
+HTTP proxy in Firefox, go through: \fBTools\fR;
+\fBOptions\fR; \fBGeneral\fR;
+\fBConnection Settings\fR;
+\fBManual Proxy Configuration\fR.
+.PP
+For Internet Explorer, go through: \fBTools\fR;
+\fBInternet Properties\fR; \fBConnections\fR;
+\fBLAN Settings\fR.
+.PP
+The Secure (SSL) Proxy should also be set to the same values, otherwise
+https: URLs will not be proxied. Note: \fBPrivoxy\fR can only
+proxy HTTP and HTTPS traffic. Do not try it with FTP or other protocols.
+HTTPS presents some limitations, and not all features will work with HTTPS
+connections.
+.PP
+For other browsers, check the documentation.
+.SH "CONFIGURATION"
+.PP
+\fBPrivoxy\fR can be configured with the various configuration
+files. The default configuration files are: \fIconfig\fR,
+\fIdefault.filter\fR, \fIdefault.action\fR and
+\fIdefault.action\fR. \fIuser.action\fR should
+be used for locally defined exceptions to the default rules in
+\fImatch-all.action\fR and \fIdefault.action\fR,
+and \fIuser.filter\fR for locally defined filters. These are
+well commented. On Unix and Unix-like systems, these are located in
+\fI/etc/privoxy/\fR by default.
+.PP
+\fBPrivoxy\fR uses the concept of \fBactions\fR
+in order to manipulate the data stream between the browser and remote sites.
+There are various actions available with specific functions for such things
+as blocking web sites, managing cookies, etc. These actions can be invoked
+individually or combined, and used against individual URLs, or groups of URLs
+that can be defined using wildcards and regular expressions. The result is
+that the user has greatly enhanced control and freedom.
+.PP
+The actions list (ad blocks, etc) can also be configured with your
+web browser at http://config.privoxy.org/
+(assuming the configuration allows it).
+\fBPrivoxy's\fR configuration parameters can also be viewed at
+the same page. In addition, \fBPrivoxy\fR can be toggled on/off.
+This is an internal page, and does not require Internet access.
+.PP
+See the \fIUser Manual\fR for a detailed
+explanation of installation, general usage, all configuration options, new
+features and notes on upgrading.
+.SH "FILES"
+
+.nf
+
+ \fI/usr/sbin/privoxy\fR
+ \fI/etc/privoxy/config\fR
+ \fI/etc/privoxy/match-all.action\fR

+ \fI/etc/privoxy/trust\fR
+ \fI/etc/privoxy/templates/*\fR
+ \fI/var/log/privoxy/logfile\fR
+.fi
+.PP
+Various other files should be included, but may vary depending on platform
+and build configuration. Additional documentation should be included in the local
+documentation directory.
+.SH "SIGNALS"
+.PP
+\fBPrivoxy\fR terminates on the \fBSIGINT\fR,
+\fBSIGTERM\fR and \fBSIGABRT\fR signals. Log
+rotation scripts may cause a re-opening of the logfile by sending a
+\fBSIGHUP\fR to \fBPrivoxy\fR. Note that unlike
+other daemons, \fBPrivoxy\fR does not need to be made aware of
+config file changes by \fBSIGHUP\fR -- it will detect them
+automatically.
+.SH "NOTES"
+.PP
+Please see the \fIUser Manual\fR on how to contact the
+developers, for feature requests, reporting problems, and other questions.
+.SH "SEE ALSO"
+.PP

+ * Revisions :
+ * $Log: project.h,v $
+ * Revision 1.129 2009/03/08 14:12:51 fabiankeil
+ * All the CSP_FLAG_FOO bit masks should be unsigned ints.
+ *
+ * Revision 1.128 2009/03/07 13:09:17 fabiankeil
+ * Change csp->expected_content and_csp->expected_content_length from
+ * size_t to unsigned long long to reduce the likelihood of integer
+ * overflows that would let us close the connection prematurely.
+ * Bug found while investigating #2669131, reported by cyberpatrol.
+ *
+ * Revision 1.127 2008/12/20 14:53:55 fabiankeil
+ * Add config option socket-timeout to control the time
+ * Privoxy waits for data to arrive on a socket. Useful
+ * in case of stale ssh tunnels or when fuzz-testing.
+ *
+ * Revision 1.126 2008/12/14 17:02:54 fabiankeil
+ * Fix a cparser warning.

+ *
+ * Revision 1.121 2008/10/09 18:21:41 fabiankeil

+ * alive where possible. Incomplete and mostly #ifdef'd out.
+ *
+ * Revision 1.120 2008/09/21 13:36:52 fabiankeil
+ * If change-x-forwarded-for{add} is used and the client
+ * sends multiple X-Forwarded-For headers, append the client's
+ * IP address to each one of them. "Traditionally" we would
+ * lose all but the last one.
+ *
+ * Revision 1.119 2008/09/20 10:04:33 fabiankeil
+ * Remove hide-forwarded-for-headers action which has
+ * been obsoleted by change-x-forwarded-for{block}.
+ *
+ * Revision 1.118 2008/09/19 15:26:29 fabiankeil
+ * Add change-x-forwarded-for{} action to block or add
+ * X-Forwarded-For headers. Mostly based on code removed

+ * Declare all members of the parsers structure immutable.
+ *
+ * Revision 1.114 2008/04/11 16:35:39 fabiankeil
+ * Oops, I forgot to shorten the URL_SPEC_INITIALIZER in my last commit.
+ *
+ * Revision 1.113 2008/04/10 14:41:04 fabiankeil
+ * Ditch url_spec's path member now that it's no longer used.
+ *
+ * Revision 1.112 2008/04/06 15:18:34 fabiankeil
+ * Oh well, rename the --enable-pcre-host-patterns option to
+ * --enable-extended-host-patterns as it's not really PCRE syntax.
+ *
+ * Revision 1.111 2008/04/06 14:54:26 fabiankeil
+ * Use PCRE syntax in host patterns when configured
+ * with --enable-pcre-host-patterns.

+ * Add hostname directive. Closes PR#1918189.
+ *
+ * Revision 1.106 2008/03/24 11:21:03 fabiankeil
+ * Share the action settings for multiple patterns in the same
+ * section so we waste less memory for gigantic block lists
+ * (and load them slightly faster). Reported by Franz Schwartau.
+ *
+ * Revision 1.105 2008/03/21 11:16:27 fabiankeil
+ * Garbage-collect csp->my_ip_addr_str and csp->my_hostname.
+ *
+ * Revision 1.104 2008/03/04 18:30:40 fabiankeil
+ * Remove the treat-forbidden-connects-like-blocks action. We now
+ * use the "blocked" page for forbidden CONNECT requests by default.
+ *
+ * Revision 1.103 2008/03/01 14:00:45 fabiankeil
+ * Let the block action take the reason for the block
+ * as argument and show it on the "blocked" page.
+ *
+ * Revision 1.102 2008/02/03 13:46:14 fabiankeil
+ * Add SOCKS5 support. Patch #1862863 by Eric M. Hopper with minor changes.

+ * - Ditch unused url_spec member pathlen.
+ *
+ * Revision 1.99 2007/07/21 11:51:36 fabiankeil
+ * As Hal noticed, checking dispatch_cgi() as the last cruncher
+ * looks like a bug if CGI requests are blocked unintentionally,
+ * so don't do it unless the user enabled the new config option
+ * "allow-cgi-request-crunching".
+ *
+ * Revision 1.98 2007/07/14 07:31:26 fabiankeil
+ * Add new csp->content_type flag (CT_DECLARED).
+ *
+ * Revision 1.97 2007/05/27 12:38:08 fabiankeil
+ * - Remove some left-overs from the switch to dedicated header filters.

+ * - Prepare for forward-override{}
+ *

+ * Introduce dynamic pcrs jobs that can resolve variables.
+ *
+ * Revision 1.94 2007/04/15 16:39:21 fabiankeil
+ * Introduce tags as alternative way to specify which
+ * actions apply to a request. At the moment tags can be
+ * created based on client and server headers.
+ *
+ * Revision 1.93 2007/03/20 15:16:34 fabiankeil
+ * Use dedicated header filter actions instead of abusing "filter".
+ * Replace "filter-client-headers" and "filter-client-headers"
+ * with "server-header-filter" and "client-header-filter".
+ *
+ * Revision 1.92 2007/03/17 15:20:05 fabiankeil
+ * New config option: enforce-blocks.
+ *
+ * Revision 1.91 2007/03/05 13:28:03 fabiankeil
+ * Add some CSP_FLAGs for the header parsers.
+ *

+ * Added config option enable-remote-http-toggle
+ * to specify if Privoxy should recognize special
+ * headers (currently only X-Filter) to change its
+ * behaviour. Disabled by default.
+ *
+ * Revision 1.79 2006/09/06 09:23:37 fabiankeil

+ * default.
+ *
+ * Revision 1.78 2006/08/31 16:25:06 fabiankeil
+ * Work around a buffer overflow that caused Privoxy to
+ * segfault if too many trusted referrers were used. Good
+ * enough for now, but should be replaced with a real

+ *
+ * Revision 1.77 2006/08/21 12:50:51 david__schmidt

+ *
+ * Revision 1.54 2002/03/09 20:03:52 jongfoster
+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.

+ * Parsing functions now handle out-of-memory gracefully by returning
+ * an error code.
+ *
+ * Revision 1.46 2002/01/17 21:06:09 jongfoster
+ * Now #defining the URLs of the config interface
+ *
+ * Minor changes to struct http_request and struct url_spec due to
+ * standardizing that struct http_request is used to represent a URL, and
+ * struct url_spec is used to represent a URL pattern. (Before, URLs were
+ * represented as seperate variables and a partially-filled-in url_spec).
+ *
+ * Revision 1.45 2002/01/09 14:33:27 oes
+ * Added HOSTENT_BUFFER_SIZE
+ *
+ * Revision 1.44 2001/12/30 14:07:32 steudten
+ * - Add signal handling (unix)
+ * - Add SIGHUP handler (unix)
+ * - Add creation of pidfile (unix)
+ * - Add action 'top' in rc file (RH)
+ * - Add entry 'SIGNALS' to manpage
+ * - Add exit message to logfile (unix)
+ *
+ * Revision 1.43 2001/11/22 21:57:51 jongfoster
+ * Making action_spec->flags into an unsigned long rather than just an
+ * unsigned int.
+ * Adding ACTION_NO_COOKIE_KEEP
+ *
+ * Revision 1.42 2001/11/05 21:42:41 steudten
+ * Include DBG() macro.
+ *
+ * Revision 1.41 2001/10/28 19:12:06 jongfoster
+ * Adding ijb_toupper()
+ *
+ * Revision 1.40 2001/10/26 17:40:47 oes
+ * Moved ijb_isspace and ijb_tolower to project.h
+ * Removed http->user_agent, csp->referrer and csp->accept_types
+ *
+ * Revision 1.39 2001/10/25 03:45:02 david__schmidt
+ * Adding a (void*) cast to freez() because Visual Age C++ won't expand the
+ * macro when called with a cast; so moving the cast to the macro def'n
+ * seems to both eliminate compiler warnings (on darwin and OS/2, anyway) and
+ * doesn't make macro expansion complain. Hope this works for everyone else
+ * too...
+ *
+ * Revision 1.38 2001/10/23 21:19:04 jongfoster
+ * New error-handling support: jb_err type and JB_ERR_xxx constants
+ * CGI functions now return a jb_err, and their parameters map is const.
+ * Support for RUNTIME_FEATUREs to enable/disable config editor
+ * Adding a few comments
+ *
+ * Revision 1.37 2001/10/14 22:14:01 jongfoster
+ * Removing name_length field from struct cgi_dispatcher, as this is
+ * now calculated at runtime from the "name" field.
+ *
+ * Revision 1.36 2001/10/10 16:45:15 oes
+ * Added LIMIT_CONNECT action and string
+ * Fixed HTTP message line termination

+ *
+ * Revision 1.35 2001/10/07 18:06:43 oes
+ * Added status member to struct http_request
+ *
+ * Revision 1.34 2001/10/07 15:45:25 oes
+ * Added url member to struct http_request and commented all
+ * members
+ *
+ * Added CT_TABOO
+ *
+ * Added ACTION_DOWNGRADE and ACTION_NO_COMPRESSION
+ *
+ * Replaced struct client_state members rejected,
+ * force, active and toggled_on with "flags" bitmap.
+ *
+ * Added CSP_FLAG_MODIFIED and CSP_FLAG_CHUNKED
+ *
+ * Added buffer_limit to struct configuration_spec
+ *
+ * Revision 1.33 2001/09/20 13:30:08 steudten
+ *
+ * Make freez() more secure in case of: if (exp) { free(z) ; a=*z }
+ * Last case will set z to NULL in free(z) and thats bad..
+ *
+ * Revision 1.32 2001/09/16 23:02:51 jongfoster
+ * Fixing warning
+ *
+ * Revision 1.31 2001/09/16 13:20:29 jongfoster
+ * Rewrite of list library. Now has seperate header and list_entry
+ * structures. Also added a large sprinking of assert()s to the list
+ * code.
+ *
+ * Revision 1.30 2001/09/13 23:52:00 jongfoster
+ * Support for both static and dynamically generated CGI pages
+ *
+ * Revision 1.29 2001/09/13 23:29:43 jongfoster
+ * Defining FORWARD_SPEC_INITIALIZER
+ *
+ * Revision 1.28 2001/09/13 23:05:50 jongfoster
+ * Changing the string paramater to the header parsers a "const".
+ *
+ * Revision 1.27 2001/08/05 16:06:20 jongfoster
+ * Modifiying "struct map" so that there are now separate header and
+ * "map_entry" structures. This means that functions which modify a
+ * map no longer need to return a pointer to the modified map.
+ * Also, it no longer reverses the order of the entries (which may be
+ * important with some advanced template substitutions).
+ *
+ * Revision 1.26 2001/07/30 22:08:36 jongfoster
+ * Tidying up #defines:
+ * - All feature #defines are now of the form FEATURE_xxx

+ * Introduced http->user_agent
+ *

+ * - Added ACTION_STRING_DEANIMATE
+ * - moved #define freez from jcc.h to project.h
+ *
+ * Revision 1.22 2001/07/15 17:51:41 jongfoster
+ * Renaming #define STATIC to STATIC_PCRE
+ *
+ * Revision 1.21 2001/07/13 14:03:19 oes
+ * - Reorganized regex header inclusion and #defines to
+ * comply to the scheme in configure.in
+ * - Added csp->content_type and its CT_* keys
+ * - Added ACTION_DEANIMATE
+ * - Removed all #ifdef PCRS
+ *
+ * Revision 1.20 2001/06/29 21:45:41 oes
+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.19 2001/06/29 13:33:36 oes
+ * - Improved comments
+ * - Introduced http_request.host_ip_addr_str
+ * - Introduced http_response.head_length
+ * - Introduced config.my_ip_addr_str, config.my_hostname,
+ * config.admin_address and config.proxy_info_url
+ * - Removed config.proxy_args_header and config.proxy_args_trailer,
+ * renamed config.proxy_args_invocation to config.proxy_args
+ * - Removed HTML snipplets and GIFs
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.18 2001/06/09 10:57:39 jongfoster
+ * Adding definition of BUFFER_SIZE.
+ * Changing struct cgi_dispatcher to use "const" strings.
+ *
+ * Revision 1.17 2001/06/07 23:15:09 jongfoster
+ * Merging ACL and forward files into config file.
+ * Moving struct gateway members into struct forward_spec
+ * Removing config->proxy_args_gateways
+ * Cosmetic: Adding a few comments
+ *
+ * Revision 1.16 2001/06/04 18:31:58 swa
+ * files are now prefixed with either `confdir' or `logdir'.
+ * `make redhat-dist' replaces both entries confdir and logdir
+ * with redhat values
+ *
+ * Revision 1.15 2001/06/04 11:28:53 swa
+ * redirect did not work due to missing /
+ *
+ * Revision 1.14 2001/06/03 11:03:48 oes
+ * Added struct map,
+ * added struct http_response,
+ * changed struct interceptors to struct cgi_dispatcher,
+ * moved HTML stuff to cgi.h
+ *
+ * Revision 1.13 2001/06/01 20:05:36 jongfoster
+ * Support for +image-blocker{}: added ACTION_IMAGE_BLOCKER
+ * constant, and removed csp->tinygif.
+ *
+ * Revision 1.12 2001/06/01 18:49:17 jongfoster
+ * Replaced "list_share" with "list" - the tiny memory gain was not
+ * worth the extra complexity.
+ *
+ * Revision 1.11 2001/06/01 10:32:47 oes
+ * Added constants for anchoring selection bitmap
+ *
+ * Revision 1.10 2001/05/31 21:33:53 jongfoster
+ * Changes for new actions file, replacing permissionsfile
+ * and parts of the config file. Also added support for
+ * list_shared.
+ *
+ * Revision 1.9 2001/05/31 17:32:31 oes
+ *
+ * - Enhanced domain part globbing with infix and prefix asterisk
+ * matching and optional unanchored operation
+ *
+ * Revision 1.8 2001/05/29 20:09:15 joergs
+ * HTTP_REDIRECT_TEMPLATE fixed.
+ *
+ * Revision 1.7 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/actionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.6 2001/05/27 22:17:04 oes
+ *
+ * - re_process_buffer no longer writes the modified buffer
+ * to the client, which was very ugly. It now returns the
+ * buffer, which it is then written by chat.
+ *
+ * - content_length now adjusts the Content-Length: header
+ * for modified documents rather than crunch()ing it.
+ * (Length info in csp->content_length, which is 0 for
+ * unmodified documents)
+ *
+ * - For this to work, sed() is called twice when filtering.
+ *
+ * Revision 1.5 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.4 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.3 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "actionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.2 2001/05/17 23:01:01 oes
+ * - Cleaned CRLF's from the sources and related files
+ *
+ * Revision 1.1.1.1 2001/05/15 13:59:03 oes
+ * Initial import of version 2.9.3 source tree

+ * 6 : ignore_leading = nonzero to ignore leading field

+ * Returns : -1 => Error: vec_len is too small to hold all the

+ * On error, vec and str may still have been overwritten.

+# "Blocked" Error Output template for Privoxy.
+#
+# NOTE: UNLIKE THE OTHER TEMPLATES, THIS ONE USES
+# JavaScript write() TO GENERATE THE PAGE IN JS_AWARE
+# BROWSERS. SYMBOL SUBSTITUTIONS THAT RESULT IN MULTILINE
+# STRINGS WILL BREAK THE JavaScript SYNTAX.
+# USE WITH CAUTION.
+#
+# USING HTML TEMPLATES:
+# ---------------------
+#
+# Template files are written in plain HTML, with a few
+# additions:
+#
+# - Lines that start with a '#' character like this one
+# are ignored
+#
+# - Each item in the below list of exported symbols will
+# be replaced by dynamically generated text, if they
+# are enclosed in '@'-characters. E.g. The string @version@
+# will be replaced by the version number of Privoxy.
+#
+# - One special application of this is to make whole blocks
+# of the HTML template disappear if the condition <name>
+# is not given. Simply enclose the block between the two
+# strings @if-<name>start and if-<name>-end@. The strings
+# should be placed in HTML comments (<!-- -->), so the
+# html structure won't be messed when the magic happens.
+#
+# USABLE SYMBOLS IN THIS TEMPLATE:
+# --------------------------------
+#
+# my-ip-addr:
+# The IP-address that the client used to reach this proxy
+# my-hostname:
+# The hostname associated with my-ip-addr
+# admin-address:
+# The email address of the pxoxy's administrator, as configured
+# in the config file
+# default-cgi:
+# The URL for the "main menu" builtin CGI of this proxy
+# menu:
+# List of <li> elements linking to the other available CGIs
+# version:
+# The version number of the proxy software
+# code-status:
+# The development status of the proxy software: "alpha", "beta",
+# or "stable".
+# homepage:
+# The URL of the SourceForge ijbswa project, who maintains this
+# software.
+#

+# The request's protocol: http:// or https://
+# hostport:
+# The host and port part of the blocked request's URL.
+# path:
+# The path part of the blocked request's URL.
+# path-ue:
+# The path part of the blocked request's URL, url-encoded.
+#
+#
+# CONDITIONAL SYMBOLS FOR THIS TEMPLATE AND THEIR DEPANDANT SYMBOLS:
+# ------------------------------------------------------------------
+#
+# unstable:
+# This is an alpha or beta release of the proxy software
+# have-adminaddr-info:
+# An e-mail address for the local Privoxy adminstrator has

+#
+# Forwarding-failed template for Privoxy.
+#
+#
+# USING HTML TEMPLATES:
+# ---------------------
+#
+# Template files are written in plain HTML, with a few
+# additions:
+#
+# - Lines that start with a '#' character like this one
+# are ignored
+#
+# - Each item in the below list of exported symbols will
+# be replaced by dynamically generated text, if they
+# are enclosed in '@'-characters. E.g. The string @version@
+# will be replaced by the version number of Privoxy.
+#
+# - One special application of this is to make whole blocks
+# of the HTML template disappear if the condition <name>
+# is not given. Simply enclose the block between the two
+# strings @if-<name>start and if-<name>-end@. The strings
+# should be placed in HTML comments (<!-- -->), so the
+# html structure won't be messed when the magic happens.
+#
+# USABLE SYMBOLS IN THIS TEMPLATE:
+# --------------------------------
+#
+# my-ip-addr:
+# The IP-address that the client used to reach this proxy
+# my-hostname:
+# The hostname associated with my-ip-addr
+# admin-address:
+# The email address of the pxoxy's administrator, as configured
+# in the config file
+# default-cgi:
+# The URL for the "main menu" builtin CGI of this proxy
+# menu:
+# List of <li> elements linking to the other available CGIs
+# version:
+# The version number of the proxy software
+# code-status:
+# The development status of the proxy software: "alpha", "beta",
+# or "stable".
+# homepage:
+# The URL of the SourceForge ijbswa project, who maintains this
+# software.
+#
+# gateway
+# The IP or hostname of the forwarding server
+# hostport:
+# The host and port part of the request that lead to this problem
+# path:
+# The path part of the request that lead to this problem
+# error-message:
+# The failure reason.
+# forwarding-type:
+# The type of the forwarding request: "socks4-", "socks4a-"
+# or (in the future) "" for direct connections to the forwarder.
+#
+#
+# CONDITIONAL SYMBOLS FOR THIS TEMPLATE AND THEIR DEPANDANT SYMBOLS:
+# ------------------------------------------------------------------
+#
+# unstable:
+# this is an alpha or beta release of the proxy software
+# have-adminaddr-info:
+# An e-mail address for the local Privoxy adminstrator has
+# been specified and is available through the "admin-address"
+# symbol
+# have-proxy-info:
+# A URL for online documentation about this proxy has been
+# specified and is available through the "proxy-info-url"
+# symbol
+# have-help-info:
+# If either have-proxy-info is true or have-adminaddr-info is
+# true, have-help-info is true. Used to conditionally include
+# a grey box for any and all help info.

+# - Each item in the below list of exported symbols will

+# - One special application of this is to make whole blocks
+# of the HTML template disappear if the condition <name>
+# is not given. Simply enclose the block between the two
+# strings @if-<name>start and if-<name>-end@. The strings

+=head1 NAME
+
+B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
+
+=head1 SYNOPSIS
+
+B<privoxy-log-parser> [B<--accept-unknown-messages>] [B<--html-output>]
+[B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--show-ineffective-filters>]
+[B<--version>]
+
+=head1 DESCRIPTION
+
+B<privoxy-log-parser> reads Privoxy log messages and
+
+- syntax-highlights recognized lines,
+
+- reformats some of them for easier comprehension,
+
+- filters out less useful messages, and
+
+- (in some cases) calculates additional information,
+ like the compression ratio or how a filter affected
+ the content size.
+
+With B<privoxy-log-parser> you should be able to increase Privoxy's log level
+without getting confused by the resulting amount of output. For example for
+"debug 64" B<privoxy-log-parser> will (by default) only show messages that
+affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
+will hide the "filter foo caused 0 hits" message.
+
+=head1 OPTIONS
+
+[B<--accept-unknown-messages>] Don't print warnings in case of unknown messages,
+just don't highlight them.
+
+[B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
+omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
+This option is only intended to make embedding log excerpts in web pages easier.
+It does not excape any input!
+
+[B<--no-msecs>] Don't expect milisecond resolution
+
+[B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
+the filtered output is piped into less in which case the ANSI control
+codes don't work, or if the terminal itself doesn't support the control
+codes.
+
+[B<--show-ineffective-filters>] Don't suppress log lines for filters
+that didn't modify the content.
+
+[B<--version>] Print version and exit.
+
+=head1 EXAMPLES
+
+To monitor a log file:
+
+tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
+
+Replace '-F' with '-f' if your tail implementation lacks '-F' support
+or if the log won't get rotated anyway. The log file location depends
+on your system (Doh!).
+
+To monitor Privoxy without having it write to a log file:
+
+privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
+
+Again, the config file location depends on your system. Output redirection
+depends on your shell, the above works with bourne shells.
+
+To read a processed Privoxy log file from top to bottom, letting the content
+scroll by slightly faster than you can read:
+
+B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
+
+This is probably only useful to fill screens in the background of haxor movies.
+
+=head1 CAVEATS
+
+Syntax highlighting with ANSI escape sequences will look strange
+if your background color isn't black.
+
+Some messages aren't recognized yet and will not be fully highlighted.
+
+B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
+using earlier Privoxy versions will probably result in an increased amount
+of unrecognized log lines.
+
+Privoxy's log files tend to be rather large. If you use HTML
+highlighting some browsers can't handle them, get confused and
+will eventually crash because of segmentation faults or unexpected
+exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
+fault.
+
+=head1 BUGS
+
+Many settings can't be controlled through command line options yet.

+[B<--version>]
+
+=head1 DESCRIPTION
+
+Privoxy-Regression-Test is supposed to one day become
+a regression test suite for Privoxy. It's not quite there
+yet, however, and can currently only test header actions,
+check the returned status code for requests to arbitrary
+URLs and verify which actions are applied to them.
+
+Client header actions are tested by requesting
+B<http://p.p/show-request> and checking whether
+or not Privoxy modified the original request as expected.
+
+The original request contains both the header the action-to-be-tested
+acts upon and an additional tagger-triggering header that enables
+the action to test.
+
+Applied actions are checked through B<http://p.p/show-url-info>.
+
+=head1 CONFIGURATION FILE SYNTAX
+
+Privoxy-Regression-Test's configuration is embedded in
+Privoxy action files and loaded through Privoxy's web interface.
+
+It makes testing a Privoxy version running on a remote system easier
+and should prevent you from updating your tests without updating Privoxy's
+configuration accordingly.
+
+A client-header-action test section looks like this:
+
+ # Set Header = Referer: http://www.example.org.zwiebelsuppe.exit/
+ # Expect Header = Referer: http://www.example.org/
+ {+client-header-filter{hide-tor-exit-notation} -hide-referer}
+ TAG:^client-header-filter\{hide-tor-exit-notation\}$
+
+The example above causes Privoxy-Regression-Test to set
+the header B<Referer: http://www.example.org.zwiebelsuppe.exit/>
+and to expect it to be modified to
+B<Referer: http://www.example.org/>.
+
+When testing this section, Privoxy-Regression-Test will set the header
+B<X-Privoxy-Control: client-header-filter{hide-tor-exit-notation}>
+causing the B<privoxy-control> tagger to create the tag
+B<client-header-filter{hide-tor-exit-notation}> which will finally
+cause Privoxy to enable the action section.
+
+Note that the actions itself are only used by Privoxy,
+Privoxy-Regression-Test ignores them and will be happy
+as long as the expectations are satisfied.
+
+A fetch test looks like this:
+
+ # Fetch Test = http://p.p/user-manual
+ # Expect Status Code = 302
+
+It tells Privoxy-Regression-Test to request B<http://p.p/user-manual>
+and to expect a response with the HTTP status code B<302>. Obviously that's
+not a very thorough test and mainly useful to get some code coverage
+for Valgrind or to verify that the templates are installed correctly.
+
+If you want to test CGI pages that require a trusted
+referer, you can use:
+
+ # Trusted CGI Request = http://p.p/edit-actions
+
+It works like ordinary fetch tests, but sets the referer
+header to a trusted value.
+
+If no explicit status code expectation is set, B<200> is used.
+
+To verify that a URL is blocked, use:
+
+ # Blocked URL = http://www.example.com/blocked
+
+To verify that a specific set of actions is applied to an URL, use:
+
+ # Sticky Actions = +block{foo} +handle-as-empty-document -handle-as-image
+ # URL = http://www.example.org/my-first-url
+
+The sticky actions will be checked for all URLs below it
+until the next sticky actions directive.
+
+=head1 TEST LEVELS
+
+All tests have test levels to let the user
+control which ones to execute (see I<OPTIONS> below).
+Test levels are either set with the B<Level> directive,
+or implicitly through the test type.
+
+Block tests default to level 7, fetch tests to level 6,
+"Sticky Actions" tests default to level 5, tests for trusted CGI
+requests to level 3 and client-header-action tests to level 1.
+
+=head1 OPTIONS
+
+B<--debug bitmask> Add the bitmask provided as integer
+to the debug settings.
+
+B<--forks forks> Number of forks to start before executing
+the regression tests. This is mainly useful for stress-testing.
+
+B<--fuzzer-address> Listening address used when executing
+the regression tests. Useful to make sure that the requests
+to load the regression tests don't fail due to fuzzing.
+
+B<--fuzzer-feeding> Ignore some errors that would otherwise
+cause Privoxy-Regression-Test to abort the test because
+they shouldn't happen in normal operation. This option is
+intended to be used if Privoxy-Regression-Test is only
+used to feed a fuzzer in which case there's a high chance
+that Privoxy gets an invalid request and returns an error
+message.
+
+B<--help> Shows available command line options.
+
+B<--header-fuzzing> Modifies linear white space in
+headers in a way that should not affect the test result.
+
+B<--level level> Only execute tests with the specified B<level>.
+
+B<--loop count> Loop through the regression tests B<count> times.
+Useful to feed a fuzzer, or when doing stress tests with
+several Privoxy-Regression-Test instances running at the same
+time.
+
+B<--max-level max-level> Only execute tests with a B<level>
+below or equal to the numerical B<max-level>.
+
+B<--max-time max-time> Give Privoxy B<max-time> seconds
+to return data. Increasing the default may make sense when
+Privoxy is run through Valgrind, decreasing the default may
+make sense when Privoxy-Regression-Test is used to feed
+a fuzzer.
+
+B<--min-level min-level> Only execute tests with a B<level>
+above or equal to the numerical B<min-level>.
+
+B<--privoxy-address proxy-address> Privoxy's listening address.
+If it's not set, the value of the environment variable http_proxy
+will be used. B<proxy-address> has to be specified in http_proxy
+syntax.
+
+B<--retries retries> Retry B<retries> times.
+
+B<--test-number test-number> Only run the test with the specified
+number.
+
+B<--show-skipped-tests> Log skipped tests even if verbose mode is off.
+
+B<--verbose> Log succesful and skipped tests.
+
+B<--version> Print version and exit.
+
+The second dash is optional, options can be shortened,
+as long as there are no ambiguities.
+
+=head1 PRIVOXY CONFIGURATION
+
+Privoxy-Regression-Test is shipped with B<regression-tests.action>
+which aims to test all official client-header modifying actions
+and can be used to verify that the templates and the user manual
+files are installed correctly.
+
+To use it, it has to be copied in Privoxy's configuration
+directory, and afterwards referenced in Privoxy's configuration
+file with the line:
+
+ actionsfile regression-tests.action
+
+In general, its tests are supposed to work without changing
+any other action files, unless you already added lots of
+taggers yourself. If you are using taggers that cause problems,
+you might have to temporary disable them for Privoxy's CGI pages.
+
+Some of the regression tests rely on Privoxy features that
+may be disabled in your configuration. Tests with a level below
+7 are supposed to work with all Privoxy configurations (provided
+you didn't build with FEATURE_GRACEFUL_TERMINATION).
+
+Tests with level 9 require Privoxy to deliver the User Manual,
+tests with level 12 require the CGI editor to be enabled.
+
+=head1 CAVEATS
+
+Expect the configuration file syntax to change with future releases.
+
+=head1 LIMITATIONS
+
+As Privoxy's B<show-request> page only shows client headers,
+Privoxy-Regression-Test can't use it to test Privoxy actions
+that modify server headers.
+
+As Privoxy-Regression-Test relies on Privoxy's tag feature to
+control the actions to test, it currently only works with
+Privoxy 3.0.7 or later.
+
+At the moment Privoxy-Regression-Test fetches Privoxy's
+configuration page through I<curl>(1), therefore you have to
+have I<curl> installed, otherwise you won't be able to run
+Privoxy-Regression-Test in a meaningful way.

+# Sample Trustfile for Privoxy
+
+# For this file to have any effect, the line in the main config file beginning
+# with "trustfile" must be uncommented, with the name of this file following the
+# word "trustfile".
+
+# Trustfiles are an experimental feature used for building "whitelists"
+# of "trusted" sites (versus the usual "blacklists" technique). For more
+# detail, see http://www.privoxy.org/user-manual/config.html#TRUSTFILE.
+
+# List trusted domains here. The default is to block any URL that is NOT
+# referenced. Access to trusted domains includes all paths within that
+# domain.
+
+# Preceding a domain with a '+' character will designate that domain
+# as a "trusted referrer", meaning any requests whose HTTP "Referer" headers
+# contain an URL from that domain will be allowed, and the previously untrusted
+# host will be dynamically added to this file. Thus, this builds a "white-list"
+# of hosts the user is allowed to visit.
+
+# Note this means that the file will grow with use!
+
+# Also note that you can only trust referrers if you control the user's
+# system and make sure that there are no programs available that allow
+# to set arbitrary headers.
+
+# Preceding the domain with '~' character allows access to that domain only
+# (including all paths within that domain), but does not allow access to links
+# to other, outside domains. Sites that are added dynamically by trusted
+# referrers will include the '~' character, and thus do not become trusted
+# referrers themselves.
+
+# Example: to allow example.com and to white-list domains that appear to
+# be reached through links from example.com, uncomment this line:
+
+# +example.com
+
+# The next two lines make sure that the user can access Privoxy's
+# CGI pages, without automatically trusting their links.

+ * Revisions :
+ * $Log: urlmatch.c,v $
+ * Revision 1.47 2009/03/02 19:18:10 fabiankeil
+ * Streamline parse_http_request()'s prototype. As
+ * cparser pointed out it doesn't actually use csp.
+ *
+ * Revision 1.46 2009/02/11 19:31:32 fabiankeil
+ * Reject request lines that end with neither HTTP/1.0 nor HTTP/1.1.
+ *
+ * Revision 1.45 2008/06/21 21:19:18 fabiankeil
+ * Silence bogus compiler warning.
+ *
+ * Revision 1.44 2008/05/04 16:18:32 fabiankeil
+ * Provide parse_http_url() with a third parameter to specify
+ * whether or not URLs without protocol are acceptable.
+ *
+ * Revision 1.43 2008/05/04 13:30:55 fabiankeil
+ * Streamline parse_http_url()'s prototype.
+ *
+ * Revision 1.42 2008/05/04 13:24:16 fabiankeil
+ * If the method isn't CONNECT, reject URLs without protocol.
+ *
+ * Revision 1.41 2008/05/02 09:51:34 fabiankeil
+ * In parse_http_url(), don't muck around with values
+ * that are none of its business: require an initialized
+ * http structure and never unset http->ssl.
+ *
+ * Revision 1.40 2008/04/23 16:12:28 fabiankeil
+ * Free with freez().
+ *
+ * Revision 1.39 2008/04/22 16:27:42 fabiankeil
+ * In parse_http_request(), remove a pointless
+ * temporary variable and free the buffer earlier.
+ *
+ * Revision 1.38 2008/04/18 05:17:18 fabiankeil
+ * Mark simplematch()'s parameters as immutable.
+ *
+ * Revision 1.37 2008/04/17 14:53:29 fabiankeil
+ * Move simplematch() into urlmatch.c as it's only
+ * used to match (old-school) domain patterns.
+ *
+ * Revision 1.36 2008/04/14 18:19:48 fabiankeil
+ * Remove now-pointless cast in create_url_spec().
+ *
+ * Revision 1.35 2008/04/14 18:11:21 fabiankeil
+ * The compiler might not notice it, but the buffer passed to
+ * create_url_spec() is modified later on and thus shouldn't
+ * be declared immutable.
+ *
+ * Revision 1.34 2008/04/13 13:32:07 fabiankeil
+ * Factor URL pattern compilation out of create_url_spec().
+ *
+ * Revision 1.33 2008/04/12 14:03:13 fabiankeil
+ * Remove an obvious comment and improve another one.
+ *
+ * Revision 1.32 2008/04/12 12:38:06 fabiankeil
+ * Factor out duplicated code to compile host, path and tag patterns.
+ *
+ * Revision 1.31 2008/04/10 14:41:04 fabiankeil
+ * Ditch url_spec's path member now that it's no longer used.
+ *
+ * Revision 1.30 2008/04/10 04:24:24 fabiankeil
+ * Stop duplicating the plain text representation of the path regex
+ * (and keeping the copy around). Once the regex is compiled it's no
+ * longer useful.
+ *
+ * Revision 1.29 2008/04/10 04:17:56 fabiankeil
+ * In url_match(), check the right member for NULL when determining
+ * whether there's a path regex to execute. Looking for a plain-text
+ * representation works as well, but it looks "interesting" and that
+ * member will be removed soonish anyway.
+ *
+ * Revision 1.28 2008/04/08 16:07:39 fabiankeil
+ * Make it harder to mistake url_match()'s
+ * second parameter for an url_spec.
+ *
+ * Revision 1.27 2008/04/08 15:44:33 fabiankeil
+ * Save a bit of memory (and a few cpu cycles) by not bothering to
+ * compile slash-only path regexes that don't affect the result.
+ *
+ * Revision 1.26 2008/04/07 16:57:18 fabiankeil
+ * - Use free_url_spec() more consistently.
+ * - Let it reset url->dcount just in case.
+ *
+ * Revision 1.25 2008/04/06 15:18:38 fabiankeil
+ * Oh well, rename the --enable-pcre-host-patterns option to
+ * --enable-extended-host-patterns as it's not really PCRE syntax.
+ *
+ * Revision 1.24 2008/04/06 14:54:26 fabiankeil
+ * Use PCRE syntax in host patterns when configured
+ * with --enable-pcre-host-patterns.
+ *
+ * Revision 1.23 2008/04/05 12:19:20 fabiankeil
+ * Factor compile_host_pattern() out of create_url_spec().
+ *
+ * Revision 1.22 2008/03/30 15:02:32 fabiankeil
+ * SZitify unknown_method().
+ *
+ * Revision 1.21 2007/12/24 16:34:23 fabiankeil
+ * Band-aid (and micro-optimization) that makes it less likely to run out of
+ * stack space with overly-complex path patterns. Probably masks the problem
+ * reported by Lee in #1856679. Hohoho.
+ *
+ * Revision 1.20 2007/09/02 15:31:20 fabiankeil
+ * Move match_portlist() from filter.c to urlmatch.c.
+ * It's used for url matching, not for filtering.
+ *
+ * Revision 1.19 2007/09/02 13:42:11 fabiankeil
+ * - Allow port lists in url patterns.
+ * - Ditch unused url_spec member pathlen.
+ *
+ * Revision 1.18 2007/07/30 16:42:21 fabiankeil
+ * Move the method check into unknown_method()
+ * and loop through the known methods instead
+ * of using a screen-long OR chain.
+ *
+ * Revision 1.17 2007/04/15 16:39:21 fabiankeil
+ * Introduce tags as alternative way to specify which
+ * actions apply to a request. At the moment tags can be
+ * created based on client and server headers.
+ *
+ * Revision 1.16 2007/02/13 13:59:24 fabiankeil
+ * Remove redundant log message.
+ *
+ * Revision 1.15 2007/01/28 16:11:23 fabiankeil
+ * Accept WebDAV methods for subversion
+ * in parse_http_request(). Closes FR 1581425.
+ *
+ * Revision 1.14 2007/01/06 14:23:56 fabiankeil
+ * Fix gcc43 warnings. Mark *csp as immutable
+ * for parse_http_url() and url_match().
+ * Replace a sprintf call with snprintf.
+ *
+ * Revision 1.13 2006/12/06 19:50:54 fabiankeil
+ * parse_http_url() now handles intercepted
+ * HTTP request lines as well. Moved parts
+ * of parse_http_url()'s code into
+ * init_domain_components() so that it can
+ * be reused in chat().
+ *
+ * Revision 1.12 2006/07/18 14:48:47 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.10.2.7 2003/05/17 15:57:24 oes
+ * - parse_http_url now checks memory allocation failure for
+ * duplication of "*" URL and rejects "*something" URLs
+ * Closes bug #736344
+ * - Added a comment to what might look like a bug in
+ * create_url_spec (see !bug #736931)
+ * - Comment cosmetics
+ *
+ * Revision 1.10.2.6 2003/05/07 12:39:48 oes
+ * Fix typo: Default port for https URLs is 443, not 143.
+ * Thanks to Scott Tregear for spotting this one.
+ *
+ * Revision 1.10.2.5 2003/02/28 13:09:29 oes
+ * Fixed a rare double free condition as per Bug #694713

+ *
+ * Revision 1.10.2.2 2002/09/25 14:53:15 oes

+ *
+ * Providing a single, simple url_match(pattern,url) function - rather than
+ * the 3-line match routine which was repeated all over the place.
+ *
+ * Renaming free_url to free_url_spec, since it frees a struct url_spec.
+ *
+ * Providing parse_http_url() so that URLs can be parsed without faking a
+ * HTTP request line for parse_http_request() or repeating the parsing
+ * code (both of which were techniques that were actually in use).
+ *
+ * Standardizing that struct http_request is used to represent a URL, and
+ * struct url_spec is used to represent a URL pattern. (Before, URLs were
+ * represented as seperate variables and a partially-filled-in url_spec).

+ * cparser pointed out it doesn't actually use csp.
+ *
+ * Revision 1.12 2008/05/04 16:18:32 fabiankeil
+ * Provide parse_http_url() with a third parameter to specify
+ * whether or not URLs without protocol are acceptable.
+ *
+ * Revision 1.11 2008/05/04 13:30:55 fabiankeil
+ * Streamline parse_http_url()'s prototype.
+ *
+ * Revision 1.10 2008/04/14 18:11:21 fabiankeil
+ * The compiler might not notice it, but the buffer passed to
+ * create_url_spec() is modified later on and thus shouldn't
+ * be declared immutable.
+ *
+ * Revision 1.9 2008/04/08 16:07:39 fabiankeil
+ * Make it harder to mistake url_match()'s
+ * second parameter for an url_spec.
+ *
+ * Revision 1.8 2007/09/02 15:31:20 fabiankeil
+ * Move match_portlist() from filter.c to urlmatch.c.
+ * It's used for url matching, not for filtering.
+ *
+ * Revision 1.7 2007/01/06 14:24:38 fabiankeil
+ * Mark *csp as immutable for parse_http_url()
+ * and url_match().
+ *
+ * Revision 1.6 2006/12/06 19:12:43 fabiankeil

+ *
+ * Revision 1.1 2002/01/17 20:53:46 jongfoster
+ * Moving all our URL and URL pattern parsing code to the same file - it
+ * was scattered around in filters.c, loaders.c and parsers.c.
+ *
+ * Providing a single, simple url_match(pattern,url) function - rather than
+ * the 3-line match routine which was repeated all over the place.
+ *
+ * Renaming free_url to free_url_spec, since it frees a struct url_spec.
+ *
+ * Providing parse_http_url() so that URLs can be parsed without faking a
+ * HTTP request line for parse_http_request() or repeating the parsing
+ * code (both of which were techniques that were actually in use).
+ *
+ * Standardizing that struct http_request is used to represent a URL, and
+ * struct url_spec is used to represent a URL pattern. (Before, URLs were
+ * represented as seperate variables and a partially-filled-in url_spec).

+
+# This is the place to add your personal exceptions and additions to
+# the general policies as defined in default.action. (Here they will be
+# safe from updates to default.action.) Later defined actions always
+# take precedence, so anything defined here should have the last word.
+
+# See http://www.privoxy.org/user-manual/actions-file.html, or the
+# comments in default.action, for an explanation of what an "action" is
+# and what each action does.

+# You can define a short form for a list of permissions - e.g., instead
+# of "-crunch-incoming-cookies -crunch-outgoing-cookies -filter -fast-redirects",
+# you can just write "shop". This is called an alias.
+#
+# Currently, an alias can contain any character except space, tab, '=', '{'
+# or '}'.
+# But please use only 'a'-'z', '0'-'9', '+', and '-'.
+#
+# Alias names are not case sensitive.
+#
+# Aliases beginning with '+' or '-' may be used for system action names
+# in future releases - so try to avoid alias names like this. (e.g.
+# "+crunch-all-cookies" below is not a good name)
+#
+# Aliases must be defined before they are used.
+#
+# These aliases just save typing later:
+#
++crunch-all-cookies = +crunch-incoming-cookies +crunch-outgoing-cookies
+-crunch-all-cookies = -crunch-incoming-cookies -crunch-outgoing-cookies
+ allow-all-cookies = -crunch-all-cookies -session-cookies-only -filter{content-cookies}
+ allow-popups = -filter{all-popups} -filter{unsolicited-popups}
++block-as-image = +block{Blocked image request.} +handle-as-image
+-block-as-image = -block
+
+# These aliases define combinations of actions
+# that are useful for certain types of sites:
+#
+fragile = -block -crunch-all-cookies -filter -fast-redirects -hide-referer -prevent-compression
+shop = -crunch-all-cookies allow-popups

+# Your favourite blend of filters:
+#

+
+# Allow ads for selected useful free sites:

+# don't want to have to log in manually each time. So you'd like to allow

+# And this stupid host sends streaming video with a wrong MIME type,
+# so that Privoxy thinks it is getting HTML and starts filtering:

+
+# Example of a simple "block" action. Say you've seen an ad on your
+# favourite page on example.com that you want to get rid of. You have
+# right-clicked the image, selected "copy image location" and pasted
+# the URL below while removing the leading http://, into a { +block{reason} }
+# section. Note that { +handle-as-image } need not be specified, since
+# all URLs ending in .gif will be tagged as images by the general rules
+# as set in default.action anyway:
+#
+{ +block{Nasty ads.} }
+www.example.com/nasty-ads/sponsor.gif
+
+# The URLs of dynamically generated banners, especially from large banner
+# farms, often don't use the well-known image file name extensions, which
+# makes it impossible for Privoxy to guess the file type just by looking
+# at the URL.
+# You can use the +block-as-image alias defined above for these cases.

+# Syntax:
+#
+# Generally filters start with a line like "FILTER: name description".
+# They are then referrable from the actionsfile with +filter{name}
+#
+# FILTER marks a filter as content filter, other filter
+# types are CLIENT-HEADER-FILTER, CLIENT-HEADER-TAGGER,
+# SERVER-HEADER-FILTER and SERVER-HEADER-TAGGER.
+#
+# Inside the filters, write one Perl-Style substitution (job) per line.
+# Jobs that precede the first FILTER: line are ignored.
+#
+# For Details see the pcrs manpage contained in this distribution.
+# (and the perlre, perlop and pcre manpages)
+#
+# Note that you are free to choose the delimiter as you see fit.
+#
+# Note2: In addition to the Perl options gimsx, the following nonstandard
+# options are supported:
+#
+# 'U' turns the default to ungreedy matching. Add ? to quantifiers to
+# switch back to greedy.
+#
+# 'T' (trivial) prevents parsing for backreferences in the substitute.
+# Use if you want to include text like '$&' in your substitute without
+# quoting.
+#
+# 'D' (Dynamic) allows the use of variables. Supported variables are:
+# $host, $origin (the IP address the request came from), $path and $url.
+#
+# Note that '$' is a bad choice as delimiter for dynamic filters as you
+# might end up with unintended variables if you use a variable name
+# directly after the delimiter. Variables will be resolved without
+# escaping anything, therefore you also have to be careful not to chose
+# delimiters that appear in the replacement text. For example '<' should
+# be save, while '?' will sooner or later cause conflicts with $url.

+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+=head1 NAME
+
+docbook2man-spec - convert DocBook RefEntries to Unix manpages
+
+=head1 SYNOPSIS
+
+The SGMLSpm package from CPAN. This contains the sgmlspl script which
+is used to grok this file. Use it like this:
+
+nsgmls some-docbook-document.sgml | sgmlspl docbook2man-spec.pl
+
+=head1 DESCRIPTION
+
+This is a sgmlspl spec file that produces Unix-style
+manpages from RefEntry markup.
+
+See the accompanying RefEntry man page for 'plain new' documentation. :)
+
+=head1 LIMITATIONS
+
+Trying docbook2man on non-DocBook or non-conformant SGML results in
+undefined behavior. :-)
+
+This program is a slow, dodgy Perl script.
+
+This program does not come close to supporting all the possible markup
+in DocBook, and will produce wrong output in some cases with supported
+markup.
+
+=head1 TODO
+
+Add new element handling and fix existing handling. Be robust.
+Produce cleanest, readable man output as possible (unlike some
+other converters). Follow Linux man(7) convention.
+If this results in added logic in this script,
+that's okay. The code should still be reasonably organized.
+
+Make it faster. If Perl sucks port it to another language.

+.SH NAME
+docbook2man-spec.pl \- convert DocBook RefEntries to man pages
+.SH SYNOPSIS
+
+\fBsgmlspl\fR \fBdocbook2man-spec.pl\fR
+
+
+\fBnsgmls\fR [ \fB\fIsgml document\fB\fR ]\fB| sgmlspl\fR \fBdocbook2man-spec.pl\fR
+
+.SH "DESCRIPTION"
+.PP
+\fBdocbook2man\fR is a sgmlspl spec file that produced man
+pages (using the -man macros) from DocBook RefEntry markup.
+.PP
+The program reads ESIS produced by nsgmls (or other SGML parsers) from
+standard input. Markup not found in RefEntry is discarded.
+.PP
+Its output, the converted man pages, are written to the current directory. If
+RefMeta information is not specified in a
+RefEntry, then the man page will be written to standard
+output.
+.PP
+The file \fImanpage.links\fR will also be created, which contains
+any aliases of the manpages generated. This file is in the format:
+
+.nf
+\fI<man page>\fR \fI<alias
+manpage>\fR
+.fi
+.PP
+The \fImanpage.refs\fR file keeps track of
+XRef references. Note that if the input document has any
+forward references, then \fBdocbook2man\fR may have to be
+invoked twice (the first time updating \fImanpage.refs\fR) to
+resolve them.
+.SH "REQUIREMENTS"
+
+The SGMLSpm package from CPAN. This package includes the sgmlspl script
+that is also needed.
+.SH "LIMITATIONS"
+.PP
+Trying \fBdocbook2man\fR on non-DocBook or non-conformant
+SGML results in undefined behavior. :-)
+.PP
+This program is a slow, dodgy Perl script.
+.PP
+This program does not come close to supporting all the possible markup
+in DocBook, and may produce wrong output in some cases with supported
+markup.
+.SH "TO DO"
+.PP
+Obvious stuff:
+.TP 0.2i
+\(bu
+Fix \fBdocbook2man\fR breakages found in
+the test documents, especially
+\fIweird.sgml\fR.
+.TP 0.2i
+\(bu
+Add new element handling and fix existing handling.
+Be robust.
+.TP 0.2i
+\(bu
+Produce cleanest, readable man output as possible (unlike some
+other converters). Follow Linux
+\fBman\fR(7)
+convention. As conversion to man pages is usually not done very often, it is
+better to be slower/more complicated than to produce wrong output. Also if
+someone wants to give up using DocBook for whatever reason, the last-converted
+man pages can then be maintained manually.
+.TP 0.2i
+\(bu
+Make it faster. I think most of the speed problems so far is with parsing
+ESIS. Rewrite \fISGMLS.pm\fR with C and/or get input directly
+from \fBSP\fR.
+.TP 0.2i
+\(bu
+Support other (human) languages. But what to do with non-ASCII charsets?
+SGMLSpm doesn't report them and \fBroff\fR does not grok them.
+[Comment: text after enclosed lists (and SS blocks) will break docbook2man]
+If we do this, more people can use DocBook.

+######################################################################
+
+This process/script is used in the production environment for the
+LDP. It relies on the HTMLDOC software package (GPL'ed) which can be
+obtained from the Easy Software Products (c) web site:
+
+ http://www.easysw.com/htmldoc/
+
+This process creates a PDF variant from the single-file HTML
+representation of a DocBook SGML (or XML) instance. The simple
+wrapper script (ldp_print) assumes that the file was created using
+{open}jade in a manner similar to:
+
+ jade -t sgml -i html -V nochunks -d $style $fname > $fname.html
+
+Give the script the filename as an argument. It will then parse the
+file into 'title.html' and 'body.html' and send each to htmldoc (as
+the corresponding title page and body of the document).
+
+
+CAVEATS
+=======
+
+o Assumes perl is in /usr/bin; adjust if necessary
+
+o You may need to specify where the htmldoc executable resides.
+ The script assumes it's within your $PATH.
+
+o If you want Postscript as an output variant, uncomment the
+ appropriate lines (see below).
+
+o Relies on output from a DocBook instance created via DSSSL/{open}jade!
+
+o Cleans up (removes) the intermediate files it creates (but not the
+ PDF or Postscript files, obviously!)
+
+o Works silently; PDF (PostScript) will be created in the same directory
+ as was specified for the input (single-file HTML) file.
+
+o Provided without warranty or support!
+
+o I ran into a problem with htmldoc v1.8.8 which required a source
+ code change (I was getting a core dump from the htmldoc process).
+ Here is the change required:
+
+ htmldoc/ps-pdf.cxx :
+ 3662,3665d3661
+ < /* gjf = 11Oct2000 */
+ < if( temprow == NULL )
+ < break;
+ <
+
+ UPDATE (2001-10-10): It appears that later versions of htmldoc
+ have this problem corrected. The patch is not required.

+ * Revision 1.4 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes

+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.3 2001/05/26 01:26:34 jongfoster
+ * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.
+ * This #define cannot be set from ./configure - there's no point, it
+ * doesn't work yet. See feature request # 425722
+ *
+ * Revision 1.2 2001/05/22 17:43:35 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Many minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)

+ * http://sourceforge.net/tracker/?func=detail&atid=311118&aid=1781135&group_i…
+ * The full patch adds control keys A(select all), C(copy) and D(delete all) to the
+ * Privoxy log window menu. Select all and copy work for me without the patch
+ * (albeit without showing the accelerator keys on the menu), so the only part of the
+ * patch I've been using for the last year or so has been the ctrl-d to delete
+ * everything in the Privoxy log window.
+ *
+ * Revision 1.20 2006/08/18 02:06:25 david__schmidt
+ * Making icon go back to blue when idle.

+ *
+ * Revision 1.17.2.1 2002/08/21 17:58:40 oes
+ * - Reorder of Win32 menu
+ * - "Show Privoxy Window" now a toggle
+ * - Temp kludge to let user and default action file be edited through win32 GUI (FR 592080)

+ * Adding version information block.
+ *
+ * Revision 1.10 2001/07/19 19:14:19 haroon
+ * - Removed all #ifdef PCRS. The .rc file extension had eluded Andreas.
+ *
+ * Revision 1.9 2001/06/07 23:08:54 jongfoster
+ * Forward and ACL edit options removed.
+ * Config edit option renamed from "&Junkbuster" to "&Configuration".
+ *
+ * Revision 1.8 2001/05/31 21:37:11 jongfoster
+ * GUI changes to rename "permissions file" to "actions file".
+ *
+ * Revision 1.7 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)

+ * Cosmetic fix: // -> block comment
+ *
+ * Revision 1.5 2001/05/26 13:24:31 jongfoster
+ * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.
+ * This #define cannot be set from ./configure - there's no point, it
+ * doesn't work yet. See feature request # 425722
+ * (I missed this file in my original checkin)
+ *
+ * Revision 1.4 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.3 2001/05/25 22:33:40 jongfoster
+ * CRLF->LF
+ *
+ * Revision 1.2 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.

+ * Revision 1.2 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.1.1.1 2001/05/15 13:59:08 oes
+ * Initial import of version 2.9.3 source tree

+ *
+ * File : $Source: /cvsroot/ijbswa/current/w32svrapi.c,v $
+ *
+ * Purpose : Win32 Services API for Privoxy.
+ * Provides the implementation of an Win32 service to
+ * allow the code to directly register and run as a
+ * native Windows service application.
+ *
+ * Since Win9x/ME platforms don't provide or support
+ * running programs as services, this code uses runtime
+ * loading and calling of the Win32 Service API, to
+ * prevent the possibility of getting "entry point not
+ * found" type errors on unsupported platforms. This adds
+ * a little more complexity to the code, but it is worth
+ * doing to provide that isolation.
+ *
+ * Copyright : Written by and Copyright (C) 2003, 2006 members of

+ *
+ * Since Win9x/ME platforms don't provide or support

+ * a little more complexity to the code, but it is worth
+ * doing to provide that isolation.
