-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
-GNU C Library written by Ulrich Drepper.

-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

- 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.

-
-*** 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

-- 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)

-- 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 (?)
-- Fix build failure where certain features were disabled.
-- 'blocked-compact' template is removed. Various CGI improvements,
- including an adaptive 'blocked' template.

-
-*** 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/

- (checkerboard) is now the default.
-- RPM spec file make over.
-
-
-*** Version 2.9.12 Beta ***
-

- 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
-- Made --no-daemon mode log to tty instead of logfile.
-- Various spec file and init script cleanups and improvements (Redhat and
- SuSE).
-- CGI Editor works on OS/2 now.
-- Fix restart failure where sockets were in TIME_WAIT.
-- Fixes for actions cgi editor, make sure we have right file.
-- A --pidfile command line option now, in addition to --help,
- --version, --no-daemon, --user and configfile. --no-daemon replaces
- the former -d option and _DEBUG define. --user will drop privileges
- to the specified user.
-- Signal handling cleanups (*nix).
-- CGI actions editor improvements and fixes.
-- Error handling improvements, especially out of memory.
-- Default re_filterfile fix that caused spurious IJB logos
- (instead of 'blank').
-- configure.in threading fixes for Solaris.
-- Various other minor fixes.
-
-
-*** Version 2.9.11 Beta Changes ***
-
-- Add "session" cookie concept where cookies exist for the life
-of that browser session only (ie never goes to disk).
-- Checks for correct header length.
-- Fix user:pass@host.domain.com auth bug.
-- Better signal handling on *nix.
-- Fix CFLAGS hard-coded in configure.in
-- Fix threading bug re: gethostbyname() that caused random
-URLs to fail in some cases.
-
-
-*** Version 2.9.11 Alpha Changes ***
-
-- A web-based editor for the actions file is included (go to http://i.j.b/)
-- Web-based toggle IJB on/off support.
-- Cookie handling has changed - the new +no-cookies-keep feature is now the
-default.
-- actionsfile is renamed to ijb.action.
-- junkbstr.txt is now config.txt on Win32.
-- Support for running IJB as a UNIX daemon process has improved.
-- Unix daemon now returns error code on failed start.
-- Timestamps in logfile and jarfile now.
-- Fix for the Netscape bug reintroduced in 2.9.9.
-- 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

-# - 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
-# change first
-# - 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

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

--------------------------------------------------------------------------------
-
-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.

-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.
-
-Please also check the status of your request a few days after submitting it, as
-we may request additional information. If you use a SF id, you should
-automatically get a mail when someone responds to your request.
-
-The appendix of the Privoxy User Manual also has helpful information on
-understanding actions, and action debugging.

- * - 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
- *

- * Remove the treat-forbidden-connects-like-blocks action. We now
- * use the "blocked" page for forbidden CONNECT requests by default.
- *
- * Revision 1.29 2008/03/01 14:00:43 fabiankeil
- * Let the block action take the reason for the block
- * as argument and show it on the "blocked" page.
- *
- * Revision 1.28 2007/12/11 21:08:29 fabiankeil
- * Let the CGI editor suggest a forward-override
- * parameter whose syntax is actually valid.
- *
- * Revision 1.27 2007/11/10 15:04:08 fabiankeil
- * Tell the CGI editor about +hide-referrer{conditional-forge}.
- *
- * Revision 1.26 2007/06/01 16:54:28 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 1.25 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 1.24 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 1.23 2006/10/09 10:26:18 fabiankeil
- * Changed the path in set-image-blocker's redirection default to
- * "send-banner?type=pattern" instead of "show-banner?type=pattern"
- * which isn't caught by Privoxy. Fixes BR 1573468.
- *
- * Changed hide-user-agent's default value to "Privoxy VERSION".
- *
- * Changed hide-referrer's default fake value to "http://www.privoxy.org/".
- * A static referrer is obviously fake anyway, so we might as well
- * advertise ourselves.
- *
- * Revision 1.22 2006/09/01 17:14:18 hal9
- * Re-ordered the actions list so that they display in the actions editor in
- * alphabetical order. Some of the new actions were "out of order".
- *
- * Revision 1.21 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 1.20 2006/08/03 02:46:41 david__schmidt
- * Incorporate Fabian Keil's patch work:http://www.fabiankeil.de/sourcecode/privoxy/
- *
- * Revision 1.19 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 1.17.2.3 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 1.17.2.2 2002/09/25 15:25:25 oes
- * Added more aliases for prehistoric action names
- *
- * Revision 1.17.2.1 2002/08/02 12:50:47 oes
- * Consistency with docs: Change default name for action from hide-referer to hide-referrer
- *
- * Revision 1.17 2002/05/14 21:25:55 oes
- * Renamed prevent-(setting/reading)-cookies to crunch-(incoming/outgoing)-cookies

- *
- * Revision 1.6 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 1.23 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
- * 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 1.14 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.

- * Revision 1.18 2008/03/30 14:52:00 fabiankeil
- * Rename load_actions_file() and load_re_filterfile()
- * 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.

- * Name in version string changed from junkbuster to Privoxy.
- *
- * Revision 1.7 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.6 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 1.5 2002/03/03 09:18:03 joergs
- * Made jumbjuster work on AmigaOS again.
- *
- * Revision 1.4 2001/10/07 15:35:13 oes
- * Replaced 6 boolean members of csp with one bitmap (csp->flags)
- *
- * Revision 1.3 2001/09/12 22:54:51 joergs
- * Stacksize of main thread increased.
- *
- * Revision 1.2 2001/05/23 00:13:58 joergs
- * AmigaOS support fixed.
- *
- * Revision 1.1.1.1 2001/05/15 13:58:46 oes

- *
- * 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

- *
- * 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

- *
- * 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

- * Use a transparent background for the PNG replacement pattern.
- *

- *
- * 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.

- * 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

- * 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
- * reside on https:// locations which browsers don't advertize as
- * referrers. Closes bug #749916, thanks to Jeff Epler for the
- * hint. Goodbye One-Click[tm] toggling :-(
- *
- * 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 1.64 2002/04/24 02:17:21 oes
- * - Better descriptions for CGIs
- * - Hide edit-actions, more shortcuts

- * Revision 1.63 2002/04/15 19:06:43 jongfoster
- * Typos
- *
- * Revision 1.62 2002/04/10 19:59:46 jongfoster
- * Fixes to #include in templates:
- * - Didn't close main file if loading an included template fails.
- * - I'm paranoid and want to disallow "#include /etc/passwd".
- *
- * Revision 1.61 2002/04/10 13:37:48 oes
- * Made templates modular: template_load now recursive with max depth 1
- *
- * Revision 1.60 2002/04/08 20:50:25 swa
- * fixed JB spelling

- * 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

- * Added GIF images again
- *
- * Revision 1.46 2002/03/07 03:48:38 oes
- * - Changed built-in images from GIF to PNG
- * (with regard to Unisys patent issue)
- * - Added a 4x4 pattern PNG which is less intrusive
- * than the logo but also clearly marks the deleted banners
- *
- * Revision 1.45 2002/03/06 22:54:35 jongfoster
- * Automated function-comment nitpicking.
- *
- * Revision 1.44 2002/03/05 22:43:45 david__schmidt
- * - Better error reporting on OS/2

- * address is available of failed attempt (a la no such domain)
- *
- * 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.
- *
- * Revision 1.41 2002/01/17 20:56:22 jongfoster
- * Replacing hard references to the URL of the config interface
- * with #defines from project.h

- * Fixing a compiler warning
- *
- * Revision 1.38 2001/11/13 00:31:21 jongfoster
- * - Adding new CGIs for use by non-JavaScript browsers:
- * edit-actions-url-form
- * edit-actions-add-url-form
- * edit-actions-remove-url-form
- * - Fixing make_menu()'s HTML generation - it now quotes the href parameter.
- * - 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

- * In this context, "unexpected" means "anything other
- * than JB_ERR_MEMORY or JB_ERR_CGI_PARAMS" - CGIs are
- * expected to handle all other errors internally,
- * since they can give more relavent error messages
- * that way.
- *
- * Note this is not a true CGI, it takes an error
- * code rather than a map of parameters.
- *
- * Parameters :
- * 1 : csp = Current client state (buffers, headers, etc...)
- * 2 : rsp = http_response data structure for output
- * 3 : error_to_report = Error code to report.
- *
- * Returns : JB_ERR_OK on success
- * JB_ERR_MEMORY on out-of-memory error.

- * Revision 1.35 2008/05/21 15:24:37 fabiankeil
- * Mark csp as immutable for a bunch of functions.
- *
- * Revision 1.34 2008/04/17 14:40:48 fabiankeil
- * Provide get_http_time() with the buffer size so it doesn't
- * have to blindly assume that the buffer is big enough.
- *
- * Revision 1.33 2007/01/28 13:41:17 fabiankeil
- * - Add HEAD support to finish_http_response.
- * - Add error favicon to internal HTML error messages.
- *
- * Revision 1.32 2006/12/17 17:53:39 fabiankeil
- * Suppress the toggle link if remote toggling is disabled.
- *
- * Revision 1.31 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 1.29.2.2 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 1.29.2.1 2003/12/17 16:33:28 oes
- * Added prototype of new function cgi_redirect
- *
- * 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.
- *
- * Bug report:
- * http://sourceforge.net/tracker/index.php?func=detail
- * &aid=557905&group_id=11118&atid=111118
- *
- * Revision 1.28 2002/04/26 12:54:03 oes
- * New function add_help_link
- *
- * Revision 1.27 2002/04/24 02:16:51 oes
- * Moved get_char_param, get_string_param and get_number_param here from cgiedit.c
- *
- * Revision 1.26 2002/04/10 13:38:35 oes
- * load_template signature changed
- *
- * Revision 1.25 2002/04/08 20:50:25 swa
- * fixed JB spelling
- *
- * Revision 1.24 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.23 2002/03/24 16:18:15 jongfoster
- * Removing old logo
- *
- * Revision 1.22 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.21 2002/03/07 03:48:38 oes
- * - Changed built-in images from GIF to PNG
- * (with regard to Unisys patent issue)
- * - Added a 4x4 pattern PNG which is less intrusive
- * than the logo but also clearly marks the deleted banners
- *
- * Revision 1.20 2002/03/04 17:53:22 oes
- * Fixed compiled warning
- *
- * Revision 1.19 2002/01/21 00:33:52 jongfoster
- * Adding map_block_keep() to save a few bytes in the edit-actions-list HTML.
- *
- * Revision 1.18 2001/11/16 00:46:31 jongfoster
- * Fixing compiler warnings
- *
- * Revision 1.17 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 1.16 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

- * Purpose : CGI-based actionsfile editor.
- *
- * Functions declared include: cgi_edit_*
- *
- * NOTE: The CGIs in this file use parameter names
- * such as "f" and "s" which are really *BAD* choices.
- * However, I'm trying to save bytes in the
- * edit-actions-list HTML page - the standard actions
- * file generated a 550kbyte page, which is ridiculous.
- *
- * Stick to the short names in this file for consistency.

- * Added code to detect "conventional" action files, that start

- *
- * Revision 1.13 2002/03/04 02:07:59 david__schmidt
- * Enable web editing of actions file on OS/2 (it had been broken all this time!)
- *
- * Revision 1.12 2002/03/03 09:18:03 joergs
- * Made jumbjuster work on AmigaOS again.
- *
- * Revision 1.11 2002/01/23 01:03:31 jongfoster
- * 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.

- * Revisions :

- * Revision 1.10 2008/08/31 15:59:03 fabiankeil
- * 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.

- * Adjust cgi_show_url_info() to show what forward-override{}

- * request for the CGI page would be forwarded if it wasn't a
- * CGI request).
- *
- * Revision 1.56 2007/05/21 10:50:35 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.

- *

- * Reference action files in CGI URLs by id instead
- * of using the first part of the file name.
- * Fixes BR 1694250 and BR 1590556.
- *
- * Revision 1.52 2007/02/13 15:10:26 fabiankeil
- * Apparently fopen()ing in "binary" mode doesn't require
- * #ifdefs, it's already done without them in cgiedit.c.
- *
- * Revision 1.51 2007/02/10 16:55:22 fabiankeil
- * - Show forwarding settings on the show-url-info page
- * - Fix some HTML syntax errors.
- *
- * Revision 1.50 2007/01/23 15:51:17 fabiankeil
- * Add favicon delivery functions.
- *
- * Revision 1.49 2007/01/20 16:29:38 fabiankeil
- * Suppress edit buttons for action files if Privoxy has
- * no write access. Suggested by Roland in PR 1564026.
- *
- * Revision 1.48 2007/01/20 15:31:31 fabiankeil
- * Display warning if show-url-info CGI page
- * is used while Privoxy is toggled off.

- * Use zalloc in cgi_send_user_manual.
- *
- * Revision 1.46 2007/01/02 12:49:46 fabiankeil
- * Add FEATURE_ZLIB to the list of conditional
- * defines at the show-status page.
- *
- * Revision 1.45 2006/12/28 18:16:41 fabiankeil
- * Fixed gcc43 compiler warnings, zero out cgi_send_user_manual's
- * body memory before using it, replaced sprintf calls with snprintf.
- *
- * 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
- * "conditional #defines" section
- * - Escaped ampersands in generated HTML.

- *
- * Revision 1.42 2006/11/21 15:43:12 fabiankeil
- * Add special treatment for WIN32 to make sure
- * cgi_send_user_manual opens the files in binary mode.
- * Fixes BR 1600411 and unbreaks image delivery.
- *
- * Remove outdated comment.
- *
- * 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

- * Provide an OpenSearch Description to access the
- * show-url-info page through "search engine plugins".
- *
- * Revision 1.15 2007/01/23 15:51:17 fabiankeil
- * Add favicon delivery functions.
- *
- * Revision 1.14 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 1.13 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 1.11 2002/04/05 15:50:53 oes
- * added send-stylesheet CGI
- *
- * Revision 1.10 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.9 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.8 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 1.7 2002/03/08 16:43:59 oes
- * Renamed cgi_transparent_png to cgi_transparent_image
- *
- * Revision 1.6 2002/03/07 03:48:59 oes
- * - Changed built-in images from GIF to PNG
- * (with regard to Unisys patent issue)
- *
- * Revision 1.5 2002/01/22 23:26:03 jongfoster
- * Adding cgi_transparent_gif() for http://i.j.b/t
- *
- * 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).
- *

-####################################################################

-#
-# 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

-#
-# This option is not recommended for environments with untrusted

-#
-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

-#
-# 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
-# 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 /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

-dnl Revision 1.7 2001/07/13 13:58:05 oes
-dnl Completely reorganized the selection scheme for
-dnl pcre, pcreposix, pcrs and gnu_regex:
-dnl
-dnl The presence of shared pcre, pcreposix or pcrs
-dnl libraried is now autodetected. Additionally, the
-dnl user can enforce using the built-in static variants
-dnl by specifying --disable-dynamic-(pcre|pcrs).
-dnl Care is taken to avoid that pcre is dyn, while pcreposix
-dnl is static, if both are used and that pcrs is static if
-dnl pcrs is.
-dnl
-dnl The choice between pcre, gnu or no regex for actionsfile
-dnl URL matching is now via
-dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
-dnl default being pcre.
-dnl
-dnl Revision 1.6 2001/06/29 21:56:40 oes
-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-socks4a 127.0.0.1:9050 .}
-# +forward-override{forward-socks4a 127.0.0.1:9050 proxy.example.org:8000}
-# +forward-override{forward-socks5 127.0.0.1:9050 .}
-# +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.

-# to access the host www.example.org through Tor exit node foobar.

- "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>
- <a name="exeutable">You may copy</a> 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:<br>
-
-
- <ol type="a">
- <li><a name="medium">Accompany it</a> 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,</li>
-
- <li><a name="written">Accompany it with a written
- offer,</a> 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,</li>
-
- <li><a name="distrib">Accompany it</a> 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.)</li>
- </ol>
-
- <p><a name="preferred">The source code</a> 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.</p>
-
- <p><a name="access">If distribution of executable or object
- code is made</a> 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.</p>
- </li>
-
- <li><a name="otherwise">You may not copy,</a> 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.</li>
-
- <li><a name="voluntary">You are not required</a> 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.</li>
-
- <li><a name="redistrib">Each time you redistribute</a> 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.</li>
-
- <li>
- <a name="patent">If, as a consequence of a court
- judgment</a> 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.
-
- <p><a name="invalid">If any portion</a> 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.</p>
-
- <p><a name="induce">It is not the purpose</a> 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.</p>
-
- <p><a name="clarify">This section</a> is intended to make
- thoroughly clear what is believed to be a consequence of
- the rest of this License.</p>
- </li>
-
- <li><a name="geog">If the distribution</a> 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.</li>
-
- <li><a name="revise">The Free Software Foundation</a> 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.</li>
-
- <li>
- <a name="permission">If you wish to incorporate parts</a>
- 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.
-
- <p><a name="nowarr">NO WARRANTY</a></p>
- </li>
-
- <li><a name="foc">BECAUSE THE PROGRAM IS LICENSED FREE OF

- Terms to Your New Programs</h3>
-
- <p>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.</p>
-
- <p><a name="attach">To do so,</a> 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.</p>
-
- <blockquote>
- <one line to give the program's name and a brief idea of
- what it does.> Copyright (C) 19yy <name of author>
-
- <p><a name="free">This program is free software;</a> 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.</p>
-
- <p><a name="merchant">This program</a> 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.</p>
-
- <p><a name="ifnot">You should</a> have received a copy of the
- GNU General Public License along with this program; if not,
- write to the Free Software Foundation, Inc., 675 Mass Ave,
- Cambridge, MA 02139, USA.</p>
- </blockquote>
-
- <p><a name="contact">Also add</a> information on how to contact
- you by electronic and paper mail.</p>
-
- <p><a name="short">If the program is interactive,</a> make it
- output a short notice like this when it starts in an
- interactive mode:</p>
-
- <blockquote>
- Gnomovision version 69, Copyright (C) 19yy 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.
- </blockquote>
-
- <p><a name="hypo">The hypothetical</a> 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.</p>
-
- <p><a name="disclaimer">You should also get your employer</a>
- (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:</p>

- </blockquote>
-
- <p><a name="library">This General Public License</a> 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

-.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.

-</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>
- <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>
- If you become part of the active development team, you will eventually
- need write access to our holy grail, the CVS repository. One of the
- team members will need to set this up for you. Please read
- this chapter completely before accessing via CVS.
- </para>
-
- <sect2 id="cvsaccess"><title>Access to CVS</title>
- <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
- called <literal>ijbswa</literal>, and the source tree module is called
- <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>.

- All formal documents are maintained in Docbook SGML and located in the
- <computeroutput>doc/source/*</computeroutput> directory. You will need
- <ulink url="http://www.docbook.org">Docbook</ulink>, the Docbook
- DTD's and the Docbook modular stylesheets (or comparable alternatives),
- and either <application>jade</application> or
- <application>openjade</application> (recommended) installed in order to
- build docs from source. Currently there is <ulink
- url="../user-manual/index.html"><citetitle>user-manual</citetitle></ulink>,
- <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
- contact someone involved in the documentation.
- </para>
- <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
- that it is correct, then it should be hand copied to
- <filename>config</filename>.
- </para>
- <para>
- Other, less formal documents (e.g. <filename>LICENSE</filename>) are
- maintained as plain text files in the top-level source directory.
- </para>
- <para>
- 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
- <filename>doc/webserver/*</filename>. And PDF version are kept in
- <filename>doc/pdf/*</filename>.
- </para>
- <para>
- Formal documents are built with the Makefile targets of
- <computeroutput>make dok</computeroutput>, or alternately
- <computeroutput>make redhat-dok</computeroutput>. If you have problems,
- try both. The build process uses the document SGML sources in
- <computeroutput>doc/source/*/*</computeroutput> to update all text files in
- <computeroutput>doc/text/</computeroutput> and to update all HTML
- documents in <computeroutput>doc/webserver/</computeroutput>.

-<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

- <sect1 id="newrelease"><title>Releasing a New Version</title>
- <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!
- </para>
- <para>
- 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
- main trunk, since these are separate development trees within CVS. If you
- are working on both, then this would require at least two separate check
- outs (i.e main trunk, <emphasis>and</emphasis> the stable release branch,
- which is <literal>v_3_0_branch</literal> at the moment).

-<sect1 id="general"><title>General Information</title>
-<sect2 renderas="sect3" id="who-uses"><title>Who should give &my-app; a try?</title>
- <para>
- Anyone who is interested in security, privacy, or in
- finer-grained control over their web and Internet experience.
- </para>
-</sect2>
-
-<sect2 renderas="sect3" id="bestchoice"><title>Is Privoxy the best choice for
-me?</title>
- <para>
- &my-app; is certainly a good choice, especially for those who want more
- control and security. Those with the willingness to read the documentation
- and the ability to fine-tune their installation will benefit the most.
- </para>
- <para>
- One of <application>Privoxy's</application>
- strengths is that it is highly configurable giving you the ability to
- completely personalize your installation. Being familiar with, or at least
- having an interest in learning about <ulink
- url="http://en.wikipedia.org/wiki/Http">HTTP</ulink> and other networking
- protocols, <ulink url="http://en.wikipedia.org/wiki/Html">HTML</ulink>, and
- <ulink url="http://en.wikipedia.org/wiki/Regular_expressions"><quote>Regular
- Expressions</quote></ulink>
- will be a big plus and will help you get the most out of &my-app;.
- A new installation just includes a very basic configuration. The user
- should take this as a starting point only, and enhance it as he or she
- sees fit. In fact, the user is encouraged, and expected to, fine-tune the
- configuration.
- </para>
- <para>
- Much of <application>Privoxy's</application> configuration can be done
- with a <ulink url="http://en.wikipedia.org/wiki/Web_browser">Web browser</ulink>.
- But there are areas where configuration is done using a
- <ulink url="http://en.wikipedia.org/wiki/Text_editors">text editor</ulink>
- to edit configuration files. Also note that the web-based action editor
- doesn't use authentication and should only be enabled in environments
- where all clients with access to &my-app; listening port can be trusted.
- </para>
-</sect2>
-
-<sect2 renderas="sect3" id="proxymoron"><title>What is a <quote>proxy</quote>? How does
-Privoxy work? </title>
- <para>
- A <ulink url="http://en.wikipedia.org/wiki/Proxy_server">web proxy</ulink>
- is a service, based on a software such as &my-app;, that clients
- (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>.
- </para>
- <para>
- There are many reasons to use web proxies, such as security (firewalling),
- efficiency (caching) and others, and there are any number of proxies
- to accommodate those needs.
- </para>
- <para>
- &my-app; is a proxy that is primarily focused on
- privacy enhancement, ad and junk elimination and freeing the user from
- restrictions placed on his activities. Sitting between your browser(s) and the Internet,
- it is in a perfect position to filter outbound personal information that your
- browser is leaking, as well as inbound junk. It uses a variety of techniques to do
- this, all of which are under your complete control via the various configuration
- files and options. Being a proxy also makes it easier to share
- configurations among multiple browsers and/or users.
- </para>
-</sect2>
-
-<sect2 renderas="sect3" id="otherstuff">
-<title>Does Privoxy do anything more than ad blocking?</title>

- can be used to sanitize and customize web browsing.

-Junkbuster at all?</title>
-<para>
- Though outdated, <ulink url="http://junkbusters.com/">Junkbusters Corporation</ulink>
- continues to offer their original version of the <application>Internet
- Junkbuster</application>, so publishing our
- <application> Junkbuster</application>-derived software under the same name
- led to confusion.

-<para>
- There are also potential legal complications from our use of the

- <ulink url="http://junkbusters.com/">Junkbusters Corporation</ulink>.
- There are, however, no objections from Junkbusters Corporation to the
- <application>Privoxy</application> project itself, and they, in fact, still
- share our ideals and goals.
-</para>

- The developers also believed that there are so many improvements over the original

- <quote><emphasis>private</emphasis> edition</quote> of the web.

-<sect2 renderas="sect3" id="differs"><title>How does Privoxy differ
-from the old Junkbuster?</title>
-<para>
- <application>Privoxy</application> picks up where
- <application>Junkbuster</application> left off.
- The new <application>Privoxy</application> still blocks ads and banners,
- still manages <ulink
- url="http://en.wikipedia.org/wiki/Browser_cookie">cookies</ulink>, and still
- helps protect your privacy. But, most of these features have been enhanced,
- and many new ones have been added, all in the same vein.
- </para>
-<para>
- <application>Privoxy</application>'s new features include:

- &newfeatures;
-<!-- end include -->
-
-</sect2>
-
-<sect2 renderas="sect3" id="whatsanad">
-<title id="knows">How does Privoxy know what is
-an ad, and what is not?</title>
-<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.
-</para>
-</sect2>
-
-<sect2 renderas="sect3">
-<title id="mistakes">Can Privoxy make mistakes?
-This does not sound very scientific.</title>
-<para>
- 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.
-</para>
-
-<para>
- But this should not be a big concern since the
- <application>Privoxy</application> 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.
- (<link linkend="badsite">See the Troubleshooting section below</link>.)
-</para>
-
-</sect2>
-
-<sect2 renderas="sect3">
-<title id="configornot">Will I have to configure Privoxy
- before I can use it?</title>
-<para>
- That depends on your expectations.
- The default installation should give you a good starting
- point, and block <emphasis>most</emphasis> ads and unwanted content,
- but many of the more advanced features are off by default, and require
- you to activate them.
-</para>
-<para>
- You do have to set up your browser to use
- <application>Privoxy</application> (see the <link
- linkend="firststep">Installation section below</link>).
-</para>
-<para>
- And you will certainly run into situations where there are false positives,
- or ads not being blocked that you may not want to see. In these cases, you
- would certainly benefit by customizing <application>Privoxy's</application>
- configuration to more closely match your individual situation. And we
- encourage you to do this. This is where the real power of
- <application>Privoxy</application> lies!
-</para>
-
-</sect2>
-
-<sect2 renderas="sect3" id="lan">
-<title>Can Privoxy run as a server on a network?</title>
- <para>
- Yes, &my-app; runs as a server already, and can easily be configured to
- <quote>serve</quote> more than one client. See <link linkend="lanconfig">
- How can I set up Privoxy to act as a proxy for my LAN</link> below.
-</para>
-</sect2>
-
-<sect2 renderas="sect3" id="browsers2"><title>My browser does the same things as
-Privoxy. Why should I use Privoxy at all?</title>
- <para>
- Modern browsers do indeed have <emphasis>some</emphasis> of the same
- functionality as <application>Privoxy</application>. Maybe this is
- adequate for you. But <application>Privoxy</application> is very
- versatile and powerful, and can probably do a number of things
- your browser just can't.
- </para>
- <para>
- In addition, a proxy is good choice if you use multiple browsers, or
- have a LAN with multiple computers since &my-app; can run as a server
- application. This way all the configuration is in one place, and you don't
- have to maintain a similar configuration for possibly many browsers or
- users.
- </para>
- <para>
- Note, however, that it's recommended to leverage both your browser's
- and <application>Privoxy's</application> privacy enhancing features
- at the same time. While your browser probably lacks some features
- &my-app; offers, it should also be able to do some things more
- reliable, for example restricting and suppressing JavaScript.
- </para>
-</sect2>
-
-<sect2 renderas="sect3" id="whytrust"><title>Why should I trust Privoxy?</title>
- <para>
- The most important reason is because you have access to
- <emphasis>everything</emphasis>, and you can control everything. You can
- check every line of every configuration file yourself. You can check every
- last bit of source code should you desire. And even if you can't read code,
- there should be some comfort in knowing that <!-- thousands of -->other people can,
- 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
- <emphasis>yours</emphasis>. In fact, we encourage this level of scrutiny. It
- is one reason we use &my-app; ourselves.
- </para>
-</sect2>
-
-<sect2 renderas="sect3" id="license"><title>Is there is a license or fee? What about a
-warranty? Registration?</title>
- <para>
- <application>Privoxy</application> is free software and licensed under the <ulink
- url="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html">GNU General Public License (GPL) version 2</ulink>.
- It is free to use, copy, modify or distribute as you wish under the terms of this

- information on the license and copyright. Or the <filename>LICENSE</filename> file
- that should be included.
- </para>
- <para>
- There is <emphasis>no warranty</emphasis> of any kind, expressed, implied or otherwise.
- That is something that would cost real money ;-) There is no registration either.
- </para>
-
-</sect2>
-
-<sect2 renderas="sect3" id="spyware">
-<title>Can Privoxy remove spyware? Adware? Viruses?</title>
-<para>
- No, at least not reliably enough to trust it. &my-app; is not designed to be
- a malware removal tool and the default configuration doesn't even try to
- filter out any malware.
-</para>
-<para>
- &my-app; could help prevent contact from (known) sites that use such

- If you run both the browser and &my-app; locally, you cannot hide your IP
- address with <application>Privoxy</application> or ultimately any other
- software alone. The server needs to know your IP address so that it knows
- where to send the responses back.
-</para>
-<para>
- There are many publicly usable "anonymous" proxies out there, which
- provide a further level of indirection between you and the web server.
-</para>
-<para>
- However, these proxies are called "anonymous" because you don't need
- to authenticate, not because they would offer any real anonymity.
- Most of them will log your IP address and make it available to the
- authorities in case you violate the law of the country they run in. In fact
- you can't even rule out that some of them only exist to *collect* information
- on (those suspicious) people with a more than average preference for privacy.

- If the problem went away, we know we have a configuration related problem.
- Now go to <ulink

- and paste the full URL of the page in question into the prompt. See which

- for this site too, to see what else might be happening (note: logging may need
- to be enabled in the main config file). Many sites are
- complex and require a number of related pages to help present their content.
- Look at what else might be used by the page in question, and what of that

- Now, armed with this information, go to

-<title>After installing Privoxy, I have to log in

-<para>
- This is a quirk that effects the installation of

- Internet Connection Sharing on Windows 2000 and Windows XP. The symptoms may
- appear to be corrupted or invalid DUN settings, or passwords.
-</para>
-
-<para>
- When setting up an NT based Windows system with

- 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.
-</para>
-
-<para>
- When setting up <application>Privoxy</application> 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
- <application>Privoxy</application>. 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!
-</para>
-
-<para>
- 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.

- 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.

- Again, the main configuration file is named <filename>config</filename> on
- Linux/Unix/BSD and OS/2, and <filename>config.txt</filename> on Windows.
- Configuration lines consist of an initial keyword followed by a list of

-<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.

-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>

- The trust mechanism is an experimental feature for building white-lists and should
- be used with care. It is <emphasis>NOT</emphasis> recommended for the casual user.
- </para>
- <para>
- If you specify a trust file, <application>Privoxy</application> will only allow
- access to sites that are specified in the trustfile. Sites can be listed
- 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.
- </para>
- <para>
- It is recommended that <application>Privoxy</application> be compiled with

-<para>
- This feature allows routing of HTTP requests through a chain of

- header to revalidation requests again, even though you configured Privoxy

-<para>
- If you have links to multiple ISPs that provide various special content
- only to their subscribers, you can configure multiple <application>Privoxies</application>
- which have connections to the respective ISPs to act as forwarders to each other, so that
- <emphasis>your</emphasis> users can see the internal content of all ISPs.
-</para>
-
-<para>
- Assume that host-a has a PPP connection to isp-a.example.net. And host-b has a PPP connection to
- isp-b.example.org. Both run <application>Privoxy</application>. Their forwarding
- configuration can look like this:
-</para>
-
-<para>
- host-a:
-</para>
-
-<para>
- <screen>
- forward / .
- forward .isp-b.example.net host-b:8118

-
-<para>
- <screen>
- forward / .
- forward .isp-a.example.org host-a:8118
-</screen>
-</para>
-
-<para>
- Now, your users can set their browser's proxy to use either
- host-a or host-b and be able to browse the internal content
- of both isp-a and isp-b.
-</para>
-
-<para>
- If you intend to chain <application>Privoxy</application> and
- <application>squid</application> locally, then chaining as
- <literal>browser -> squid -> privoxy</literal> is the recommended way.
-</para>
-
-<para>
- Assuming that <application>Privoxy</application> and <application>squid</application>
- run on the same box, your <application>squid</application> configuration could then look like this:
-</para>
-
-<para>
- <screen>
- # Define Privoxy as parent proxy (without ICP)
- cache_peer 127.0.0.1 parent 8118 7 no-query
-
- # Define ACL for protocol FTP
- acl ftp proto FTP
-
- # Do not forward FTP requests to Privoxy
- 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>
- You could just as well decide to only forward requests you suspect
- of leading to Windows executables through a virus-scanning parent proxy,
- say, on <literal>antivir.example.com</literal>, port 8010:
-</para>
-

- Please don't change the markup unless you can verify the changes
- will improve finished output!
-
- literallayout tags are particularly sensitive to where they are placed.
- The 'replaceable' and 'command' tags are used here somewhat unconventionally,
- since it seems to generate the proper formatting (at least for me :).

-<refsect1><title>Installation and Usage</title>
-<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.
-</para>
-</refsect1>
-
-
-<!-- ~~~~~ 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>
-<para>
- See the <ulink
- url="http://www.privoxy.org/user-manual/"><citetitle>User Manual</citetitle></ulink> for a detailed
- explanation of installation, general usage, all configuration options, new
- features and notes on upgrading.

- <command>SIGHUP</command> to <command>Privoxy</command>. Note that unlike

- ======================================================================
- NOTE: The left margin spacing is *important* when using 'literallayout'
- WYSISWYG!!! Don't mess this up!!! Careful with linebreaks too, ie

- For stable releases, change

-<para>
- March 2009, Privoxy 3.0.12 is released.
-</para>

-<para>
- February 2009, Privoxy 3.0.11 is released.
-</para>
-<para>
- As usual there are changes that effect the configuration. See the "ChangeLog",
- and the "What's New" section and the "Upgrader's Notes" in
- <citetitle>the User Manual</citetitle> for details and specifics.
-</para>
-<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.

-<para>
- 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
- <citetitle>User Manual</citetitle> has an explanation of all configuration
- options, and examples: http://www.privoxy.org/user-manual/.
-</para>
-<para>
- 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.

-<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

- 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

- Another feature where you will probably want to define exceptions for trusted

- 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

- 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.

- 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

-<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
- your bank, favorite shop, or newspaper.
-</para>
-
-<para>
- 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.
- Sooner or later you will want to change the rules (and read this chapter again :).

-<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

- 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>

- 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>
- matches <literal>www.ipix.com</literal>,
- <literal>pictures.epix.com</literal>, <literal>a.b.c.d.e.upix.com</literal> etc.
- </para>
- </listitem>
- </varlistentry>
- <varlistentry>
- <term><literal>www[1-9a-ez].example.c*</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.

- All actions are disabled by default, until they are explicitly enabled
- somewhere in an actions file. Actions are turned on if preceded with a

- </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

- 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
- the order they are defined in <filename>config</filename> (the default

- <para>
- The <quote>Content-Type:</quote> HTTP server header is used by the
- browser to decide what to do with the document. The value of this
- header can cause the browser to open a download menu instead of
- displaying the document by itself, even if the document's format is
- supported by the browser.
- </para>
- <para>
- The declared content type can also affect which rendering mode
- the browser chooses. If XHTML is delivered as <quote>text/html</quote>,
- many browsers treat it as yet another broken HTML document.
- If it is send as <quote>application/xml</quote>, browsers with
- XHTML support will only display it, if the syntax is correct.
- </para>
- <para>
- If you see a web site that proudly uses XHTML buttons, but sets
- <quote>Content-Type: text/html</quote>, you can use &my-app;
- to overwrite it with <quote>application/xml</quote> and validate
- the web master's claim inside your XHTML-supporting browser.
- If the syntax is incorrect, the browser will complain loudly.
- </para>
- <para>
- You can also go the opposite direction: if your browser prints
- error messages instead of rendering a document falsely declared
- as XHTML, you can overwrite the content type with
- <quote>text/html</quote> and have it rendered as broken HTML document.
- </para>
- <para>
- By default <literal>content-type-overwrite</literal> only replaces
- <quote>Content-Type:</quote> headers that look like some kind of text.
- If you want to overwrite it unconditionally, you have to combine it with

- This limitation exists for a reason, think twice before circumventing it.

- This will also shrink the images considerably (in bytes, not pixels!). If

- <listitem>
- <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.

- <para>
- For your convenience, there are a number of pre-defined filters available
- in the distribution filter file that you can use. See the examples below for
- a list.
- </para>
- <para>
- Filtering requires buffering the page content, which may appear to
- slow down page rendering since nothing is displayed until all content has
- passed the filters. (It does not really take longer, but seems that way
- since the page is not incrementally displayed.) This effect will be more

- This is very powerful feature, and potentially very intrusive.
- Filters should be used with caution, and where an equivalent
- <quote>action</quote> is not available.
- </para>
- <para>
- 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>
- action in conjunction with <literal>filter</literal>.
- </para>
- <para>
- Content filtering can achieve some of the same effects as the
- <literal><link linkend="block">block</link></literal>
- action, i.e. it can be used to block ads and banners. But the mechanism
- works quite differently. One effective use, is to block ad banners
- based on their size (see below), since many of these seem to be somewhat

- Removing the <quote>Last-Modified:</quote> header is useful for filter

- 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>
- <quote>reset-to-request-time</quote> overwrites the value of the

- 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

-<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!
- #
- {{alias}}
-
- # These aliases just save typing later:
- # (Note that some already use other aliases!)
- #
- +crunch-all-cookies = +<link linkend="CRUNCH-INCOMING-COOKIES">crunch-incoming-cookies</link> +<link linkend="CRUNCH-OUTGOING-COOKIES">crunch-outgoing-cookies</link>

-
- # These aliases define combinations of actions
- # that are useful for certain types of sites:
- #
- fragile = -<link linkend="BLOCK">block</link> -<link linkend="FILTER">filter</link> -crunch-all-cookies -<link linkend="FAST-REDIRECTS">fast-redirects</link> -<link linkend="HIDE-REFERER">hide-referrer</link> -<link linkend="PREVENT-COMPRESSION">prevent-compression</link>

-</para>
-
-<para>
- ...and put them to use. These sections would appear in the lower part of an

- example <filename>match-all.action</filename>, <filename>default.action</filename>
- and <filename>user.action</filename> file and see how all these pieces come together:
-</para>
-
-<sect3>
-<title>match-all.action</title>
-<para>
- Remember <emphasis>all actions are disabled when matching starts</emphasis>,
- so we have to explicitly enable the ones we want.
-</para>
-
-<para>
- While the <filename>match-all.action</filename> file only contains a
- single section, it is probably the most important one. It has only one
- pattern, <quote><literal>/</literal></quote>, but this pattern
- <link linkend="af-patterns">matches all URLs</link>. Therefore, the set of
- actions used in this <quote>default</quote> section <emphasis>will
- be applied to all requests as a start</emphasis>. It can be partly or
- wholly overridden by other actions files like <filename>default.action</filename>
- and <filename>user.action</filename>, but it will still be largely responsible
- for your overall browsing experience.
-</para>
-
-<para>
- Again, at the start of matching, all actions are disabled, so there is
- no need to disable any actions here. (Remember: a <quote>+</quote>
- preceding the action name enables the action, a <quote>-</quote> disables!).
- Also note how this long line has been made more readable by splitting it into
- multiple lines with line continuation.

- If you aren't a developer, there's no need for you to edit the

- the &my-app; developers and if you disagree with some of the
- sections, you should overrule them in your <filename>user.action</filename>.

-</para>
-
-<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
- our pre-defined <literal>fragile</literal> alias instead of stating the list
- of actions explicitly:

-.windowsupdate.microsoft.com
-mail.google.com</screen>
-</para>
-
-<para>
- Shopping sites are not as fragile, but they typically
- require cookies to log in, and pop-up windows for shopping
- carts or item details. Again, we'll use a pre-defined alias:

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

- breaks some sites. So disable it for popular sites where we know it misbehaves:

- 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

-/.*\.(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>
- 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.

- 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
- <filename>default.action</filename> is actively maintained by the
- <application>Privoxy</application> developers and you'll probably want

- &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.

- <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>

- Multiple filter files can be defined through the <literal> <link

- defined or modified filters go in a separately defined file such as
- <filename>user.filter</filename>.

-<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

- Use the <link linkend="FORCE-TEXT-MODE">force-text-mode</link> action
- to also filter other content.

- Just like the <link linkend="actions-file">actions files</link>, the

- <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

- 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.

-<sect2><title>Filter File Tutorial</title>
-<para>
- Now, let's complete our <quote>foo</quote> content filter. We have already defined
- the heading, but the jobs are still missing. Since all it does is to replace
- <quote>foo</quote> with <quote>bar</quote>, there is only one (trivial) job
- 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>
-</para>
-
-<para>
- Our complete filter now looks like this:
-</para>
-<para>
- <screen>FILTER: foo Replace all "foo" with "bar"
-s/foo/bar/g</screen>
-</para>
-
-<para>
- Let's look at some real filters for more interesting examples. Here you see
- 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.
-</para>

-<title>Privoxy's Template Files</title>
-<para>
- All <application>Privoxy</application> built-in pages, i.e. error pages such as the
- <ulink url="http://show-the-404-error.page"><quote>404 - No Such Domain</quote>
- error page</ulink>, the <ulink
- url="http://ads.bannerserver.example.com/nasty-ads/sponsor.html"><quote>BLOCKED</quote>
- page</ulink>
- and all pages of its <ulink url="http://config.privoxy.org/">web-based
- user interface</ulink>, are generated from <emphasis>templates</emphasis>.
- (<application>Privoxy</application> must be running for the above links to work as
- intended.)
-</para>
-
-<para>
- These templates are stored in a subdirectory of the <link linkend="confdir">configuration
- directory</link> called <filename>templates</filename>. On Unixish platforms,
- this is typically
- <ulink url="file:///etc/privoxy/templates/"><filename>/etc/privoxy/templates/</filename></ulink>.
-</para>
-
-<para>
- The templates are basically normal HTML files, but with place-holders (called symbols
- or exports), which <application>Privoxy</application> fills at run time. It
- is possible to edit the templates with a normal text editor, should you want
- to customize them. (<emphasis>Not recommended for the casual
- user</emphasis>). Should you create your own custom templates, you should use
- the <filename>config</filename> setting <link linkend="templdir">templdir</link>
- to specify an alternate location, so your templates do not get overwritten
- during upgrades.
- </para>
- <para>
- Note that just like in configuration files, lines starting
- with <literal>#</literal> are ignored when the templates are filled in.
-</para>
-
-<para>
- The place-holders are of the form <literal>@name@</literal>, 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.
-</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>
- and the source for it can be found and edited in the
- <filename>cgi-style.css</filename> template.

-<para>
- 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
- your own :/

-<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.

- 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>
- 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>
- </listitem>
-
- </itemizedlist>
-</para>
-<para>
- 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
- <application>Privoxy's</application> core features only.

-<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}

-
- { -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>:

- 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>

-
- { +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.

- Announcing Privoxy v.3.0.12
------------------------------------------------------------------
-
-Privoxy 3.0.12-stable is primarily a bugfix release.
-
-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.

- understand why or what is being done. A reader may spend a lot

- or explanation would have prevented the extra research. Please
- help your brother IJB'ers out!</P

->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.</P

->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

->,
- 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"

- picked up the thread, and started turning the software inside out, upside down,

- <A
-HREF="http://www.docbook.org"
-TARGET="_top"
->Docbook</A

- DTD's and the Docbook modular stylesheets (or comparable alternatives),
- and either <SPAN

- <SPAN

- <I
-CLASS="CITETITLE"

- SGML. These files, when built, in the top-level source directory are
- generated files! Also, the <SPAN

-> <TT
-CLASS="FILENAME"
->index.html</TT
-> (and a
- variation on this file, <TT
-CLASS="FILENAME"

- meant for inclusion with doc packages), are maintained as SGML as well.
- <SPAN

-></SPAN
->. Edit the SGML source, or
- contact someone involved in the documentation.
- </P

- 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

-> Other, less formal documents (e.g. <TT
-CLASS="FILENAME"
->LICENSE</TT

- maintained as plain text files in the top-level source directory.
- </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

->doc/webserver/*</TT
->. And PDF version are kept in
- <TT
-CLASS="FILENAME"
->doc/pdf/*</TT

- <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

-><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
- purposes.</P

- <SPAN

- </P

-><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

->3.0.1 -> 0.0.0 -> 3.0.2</TT
->.

-> 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

-> Developers should remember too that if they commit a bugfix to the stable

- outs (i.e main trunk, <SPAN

-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
-><DIV
-CLASS="SECT2"

-><A

->1.9. Can Privoxy make mistakes?
-This does not sound very scientific.</A
-></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.

-> That depends on your expectations.
- The default installation should give you a good starting
- point, and block <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->most</I
-></SPAN
-> ads and unwanted content,
- but many of the more advanced features are off by default, and require
- you to activate them. </P

- <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> (see the <A
-HREF="installation.html#FIRSTSTEP"
->Installation section below</A
->). </P
-><P
-> And you will certainly run into situations where there are false positives,
- or ads not being blocked that you may not want to see. In these cases, you
- would certainly benefit by customizing <SPAN

->Privoxy's</SPAN

- configuration to more closely match your individual situation. And we

-></H3
-><P
-> Modern browsers do indeed have <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->some</I
-></SPAN
-> of the same
- functionality as <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
->. Maybe this is
- adequate for you. But <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> is very
- versatile and powerful, and can probably do a number of things
- your browser just can't.
- </P
-><P
-> In addition, a proxy is good choice if you use multiple browsers, or
- have a LAN with multiple computers since <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> can run as a server
- application. This way all the configuration is in one place, and you don't
- have to maintain a similar configuration for possibly many browsers or
- users.
- </P
-><P
-> Note, however, that it's recommended to leverage both your browser's
- and <SPAN
-CLASS="APPLICATION"
->Privoxy's</SPAN
-> privacy enhancing features
- at the same time. While your browser probably lacks some features
- <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> offers, it should also be able to do some things more
- reliable, for example restricting and suppressing JavaScript.

-><H3
-CLASS="SECT2"
-><A
-NAME="WHYTRUST"

-><P
-> The most important reason is because you have access to
- <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->everything</I
-></SPAN
->, and you can control everything. You can
- check every line of every configuration file yourself. You can check every
- last bit of source code should you desire. And even if you can't read code,
- there should be some comfort in knowing that other people can,
- 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
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->yours</I
-></SPAN

-> 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

-></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"

->
- 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

- to differentiate filterable content because of the MIME type as reported by

-> privacy-enhancing features can be easily subverted

- be configured to only execute code from trusted sites, and be careful which sites you trust.
- For example there is no point in having <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
->
- modify the User-Agent header, if websites can get all the information they want
- through JavaScript, ActiveX, Flash, Java etc.</P
-><P
-> A few browsers disclose the user's email address in certain situations, such
- as when transferring a file by FTP. <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
->
- does not filter FTP. If you need this feature, or are concerned about the
- mail handler of your browser disclosing your email address, you might
- consider products such as <SPAN
-CLASS="APPLICATION"
->NSClean</SPAN
->.</P
-><P
-> Browsers available only as binaries could use non-standard headers to give
- out any information they can have access to: see the manufacturer's license
- agreement. It's impossible to anticipate and prevent every breach of privacy
- that might occur. The professionally paranoid prefer browsers available as
- source code, because anticipating their behavior is easier. Trust the source,

- there is little that <SPAN

-><P
-> The only exception to this is blocking by host patterns, as the client needs

- so that <SPAN
-CLASS="APPLICATION"

-> can establish the connection.
- If that name matches a host-only pattern, the connection will be blocked.</P
-><P
-> As far as ad blocking is concerned, this is less of a restriction than it may
- seem, since ad sources are often identifiable by the host name, and often
- the banners to be placed in an encrypted page come unencrypted nonetheless
- for efficiency reasons, which exposes them to the full power of

-><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
- something better behaved in its place. Other personal firewall type products

->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

- and then shift-reloading the problem page (i.e. holding down the shift key
- while clicking reload. Alternatively, flush your browser's disk and memory
- caches).</P
-><P
-> If the problem went away, we know we have a configuration related problem.
- Now go to <A
-HREF="http://config.privoxy.org/show-url-info"
-TARGET="_top"
->http://config.privoxy.org/show-url-info</A
->
- and paste the full URL of the page in question into the prompt. See which
- actions are being applied to the URL, and which matches in which actions
- files are responsible for that. It might be helpful also to look at your logs
- for this site too, to see what else might be happening (note: logging may need
- to be enabled in the main config file). Many sites are
- complex and require a number of related pages to help present their content.
- Look at what else might be used by the page in question, and what of that
- might be <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->required</I
-></SPAN
->.
- Now, armed with this information, go to
- <A
-HREF="http://config.privoxy.org/show-status"
-TARGET="_top"
->http://config.privoxy.org/show-status</A
->
- and select the appropriate actions files for editing. </P
-><P
-> You can now either look for a section which disables the actions that
- you suspect to cause the problem and add a pattern for your site there,
- or make up a completely new section for your site. In any case, the recommended
- way is to disable only the prime suspect, reload the problem page, and only
- if the problem persists, disable more and more actions until you have
- identified the culprit. You may or may not want to turn the other actions
- on again. Remember to flush your browser's caches in between any such changes!</P
-><P
-> Alternately, if you are comfortable with a text editor, you can accomplish
- the same thing by editing the appropriate actions file. Probably the easiest
- way to deal with such problems when editing by hand is to add your
- site to a <TT
-CLASS="LITERAL"
->{ fragile }</TT
-> section in <TT
-CLASS="FILENAME"
->user.action</TT
->,
- which is an alias that turns off most <SPAN
-CLASS="QUOTE"
->"dangerous"</SPAN
->
- actions, but is also likely to turn off more actions then needed, and thus lower
- your privacy and protection more than necessary, </P

-><P
-> As a last resort, you can always see if your browser has a setting that will

-><A
-NAME="DUN"
->5.5. After installing Privoxy, I have to log in
-every time I start IE. What gives?</A
-></H3
-><P
-> This is a quirk that effects the installation of
- <SPAN
-CLASS="APPLICATION"
->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

- is blocking me.</A
-></H3
-><P
-> <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> cannot act as a proxy for FTP traffic,
- so do not configure your browser to use <SPAN
-CLASS="APPLICATION"

->
- as an FTP proxy. The same is true for <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->any protocol other than HTTP
- or HTTPS (SSL)</I
-></SPAN
->.
- </P
-><P
-> Most browsers understand FTP as well as HTTP. If you connect to a site, with
- a URL like <TT
-CLASS="LITERAL"
->ftp://ftp.example.com</TT
->, your browser is making
- an FTP connection, and not a HTTP connection. So while your browser may
- speak FTP, <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> does not, and cannot proxy
- such traffic.
- </P
-><P
-> To complicate matters, some systems may have a generic <SPAN
-CLASS="QUOTE"
->"proxy"</SPAN
->
- setting, which will enable various protocols, including
- <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->both</I
-></SPAN
-> HTTP and FTP proxying! So it is possible to
- accidentally enable FTP proxying in these cases. And of course, if this
- happens, <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> will indeed cause problems since
- it does not know FTP. Newer version will give a sane error
- message if a FTP connection is attempted. Just disable the FTP setting
- and all will be well again.
- </P
-><P
-> Will <SPAN
-CLASS="APPLICATION"

- There just is not much reason, and the work to make this happen is more than
- it may seem.

-> There are potentially several factors here. First of all, the DNS resolution

- <SPAN

-CLASS="APPLICATION"
->Privoxy</SPAN
->
- merely initiates the process and hands it off, and then later reports

-><P
-> To work around the problem you can redirect those requests to an invalid

-<P>
-<A NAME="lbAD"> </A>
-<H2>OPTIONS</H2>
-
-<P>
-
-<B>Privoxy</B> may be invoked with the following command line
-options:
-<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.
-<A NAME="lbAH"> </A>
-<H2>FILES</H2>
-
-<P>
-<PRE>
-
- <I>/usr/sbin/privoxy</I>
- <I>/etc/privoxy/config</I>
- <I>/etc/privoxy/match-all.action</I>
- <I>/etc/privoxy/default.action</I>
- <I>/etc/privoxy/user.action</I>
- <I>/etc/privoxy/default.filter</I>

- <I>/etc/privoxy/templates/*</I>
- <I>/var/log/privoxy/logfile</I>
-</PRE>
-
-<P>
-
-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.
-<A NAME="lbAJ"> </A>
-<H2>NOTES</H2>
-
-<P>
-
-Please see the <I>User Manual</I> on how to contact the
-developers, for feature requests, reporting problems, and other questions.

-> 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

- Note: the config file option <A

- 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

- in <SPAN
-CLASS="emphasis"

-><P
-> For example you could tag client requests which use the
- <TT

- 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

- 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

-><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

-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

-><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,

-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

- is for our <TT

- section just below the <SPAN
-CLASS="QUOTE"

- will apply to all URLs as signified by the single forward slash at the end

-CLASS="QUOTE"

-> 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

-><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

-></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

- match <SPAN
-CLASS="QUOTE"

- to treat the block as if it were an image. But this is, of course, all wrong.

-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"

- 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.

-> Following the header line and a comment, you see the job. Note that it uses

->/</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

-CLASS="QUOTE"
->"zero

- makes this matching of arbitrary text ungreedy. (Note that the <TT

-CLASS="QUOTE"
->"a single

->. Finally, <TT

-> is
- a back-reference to the first parenthesis just like <TT

- with the difference that in the <SPAN

- (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

-NAME="QUICKSTART-AD-BLOCKING"
->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.

- <TT

- A <SPAN

- filter usage: a text replacement of <SPAN
-CLASS="QUOTE"

-> 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

->Privoxy</SPAN
-> editor at <A
-HREF="http://config.privoxy.org/show-status"

- (shortcut: <A

-> 3.0.7 beta the
- action editor is disabled by default. Check the
- <A
-HREF="config.html#ENABLE-EDIT-ACTIONS"

- <SPAN

- find a list of available symbols, which vary from template to template,

- 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

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

->:</P
-><P

-></P
-><UL
-><LI

-> The recommended way to upgrade <SPAN

->
- is working correctly and finally merge back your changes using
- <SPAN
-CLASS="APPLICATION"
->diff</SPAN
-> and maybe <SPAN
-CLASS="APPLICATION"
->patch</SPAN
->.
- </P
-><P
-> There are a number of new features in each <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> release and
- most of them have to be explicitly enabled in the configuration
- files. Old configuration files obviously don't do that and due
- to syntax changes using old configuration files with a new
- <SPAN
-CLASS="APPLICATION"
->Privoxy</SPAN
-> isn't always possible anyway.
- </P
-></LI
-><LI
-><P
->
- Note that some installers remove earlier versions completely,
- including configuration files, therefore you should really save
- any important configuration files!
- </P
-></LI
-><LI
-><P
->
- On the other hand, other installers don't overwrite existing configuration
- files, thinking you will want to do that yourself.

->
- <TT
-CLASS="FILENAME"
->standard.action</TT
-> has been merged into
- the <TT
-CLASS="FILENAME"
->default.action</TT
-> file.
- </P
-></LI
-><LI
-><P
-> In the default configuration only fatal errors are logged now.
- You can change that in the <A
-HREF="config.html#DEBUG"
->debug section</A
->
- of the configuration file. You may also want to enable more verbose
- logging until you verified that the new <SPAN
-CLASS="APPLICATION"

-> version is working
- as expected.

- *
- * Revision 1.91 2009/03/18 21:56:30 fabiankeil
- * In init_error_log(), suppress the "(Re-)Opening logfile" message if

- * 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

- *
- * 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
- * Tweak for OS/2 build happiness.
- *
- * Revision 1.43 2006/08/03 02:46:41 david__schmidt
- * Incorporate Fabian Keil's patch work:
- * http://www.fabiankeil.de/sourcecode/privoxy/
- *
- * Revision 1.42 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 1.40.2.4 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.
- *
- * Revision 1.37 2002/03/27 14:32:43 david__schmidt
- * More compiler warning message maintenance
- *
- * Revision 1.36 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.35 2002/03/24 15:23:33 jongfoster
- * Name changes
- *
- * Revision 1.34 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.33 2002/03/13 00:27:04 jongfoster
- * Killing warnings

- * Fixed compiler warnings
- *
- * Revision 1.31 2002/03/06 23:02:57 jongfoster
- * Removing tabs
- *
- * Revision 1.30 2002/03/05 22:43:45 david__schmidt
- * - Better error reporting on OS/2

- * Revision 1.28 2002/03/04 17:59:59 oes
- * Deleted deletePidFile(), cosmetics
- *
- * Revision 1.27 2002/03/04 02:08:01 david__schmidt
- * Enable web editing of actions file on OS/2 (it had been broken all this time!)
- *
- * Revision 1.26 2002/01/09 19:05:45 steudten
- * 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)
- * - Add action 'top' in rc file (RH)
- * - Add entry 'SIGNALS' to manpage

- * actionsfile and configfile.
- * Special handling for CLF added.
- *
- * Revision 1.22 2001/11/05 23:43:05 steudten
- * 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

- * 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
- *

- * Now that init_log_module() is called earlier, call show_version()
- * later on from main() directly so it doesn't get called for --help

- *
- * Revision 1.19 2007/10/14 14:12:41 fabiankeil

- *
- * 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
- *

- * Mention actual values when complaining about

- *
- * Revision 1.108 2008/05/21 15:35:08 fabiankeil
- * - Mark csp as immutable for block_acl().
- * - Remove an obsolete complaint about filter_popups().
- *
- * 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
- * CGI code. Don't bother checking if there are filters
- * 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,
- * don't generate the "501 unsupported" message for invalid
- * Max-Forwards values and don't increase negative ones.
- *
- * Revision 1.78 2007/01/28 13:41:18 fabiankeil
- * - Add HEAD support to finish_http_response.
- * - Add error favicon to internal HTML error messages.
- *
- * Revision 1.77 2007/01/12 15:36:44 fabiankeil
- * Mark *csp as immutable for is_untrusted_url()
- * and is_imageurl(). Closes FR 1237736.
- *
- * Revision 1.76 2007/01/01 19:36:37 fabiankeil
- * Integrate a modified version of Wil Mahan's
- * zlib patch (PR #895531).
- *
- * Revision 1.75 2006/12/29 18:30:46 fabiankeil
- * Fixed gcc43 conversion warnings,
- * changed sprintf calls to snprintf.
- *
- * Revision 1.74 2006/12/24 17:37:38 fabiankeil
- * Adjust comment in pcrs_filter_response()
- * to recent pcrs changes. Hohoho.
- *
- * Revision 1.73 2006/12/23 16:01:02 fabiankeil
- * Don't crash if pcre returns an error code
- * that pcrs didn't expect. Fixes BR 1621173.
- *
- * Revision 1.72 2006/12/22 18:52:53 fabiankeil
- * Modified is_untrusted_url to complain in case of
- * write errors and to give a reason when adding new

- *
- * Revision 1.52 2002/03/24 16:35:57 jongfoster
- * Removing logo

- * Cosmetics
- *
- * Revision 1.48 2002/03/13 20:25:34 oes
- * Better logging for content filters
- *
- * Revision 1.47 2002/03/13 00:30:52 jongfoster
- * Killing warnings
- * Added option of always sending redirect for imageblock,
- * currently disabled with #if 0.
- *
- * Revision 1.46 2002/03/12 01:42:49 oes
- * Introduced modular filters
- *
- * 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
- * (with regard to Unisys patent issue)
- * - Added a 4x4 pattern PNG which is less intrusive
- * than the logo but also clearly marks the deleted banners
- *
- * 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 1.14 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.
- *

- * - 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
- *

- * Remove already out-commented line left over from debugging.
- *
- * Revision 1.38 2008/10/24 17:33:00 fabiankeil
- * - Tone the "keep-alive support is experimental" warning
- * down a bit as hackish 0-chunk detection has been
- * implemented recently.
- * - 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(),
- * which would both under certain circumstances access
- * reusable_connection[MAX_REUSABLE_CONNECTIONS]. Oops.
- *
- * Revision 1.36 2008/10/18 19:49:15 fabiankeil
- * - Factor close_unusable_connections() out of
- * get_reusable_connection() to make sure we really check
- * all the remembered connections, not just the ones before
- * the next reusable one.
- * - Plug two file descriptor leaks. Internally marking
- * connections as closed doesn't cut it.
- *
- * Revision 1.35 2008/10/17 17:12:01 fabiankeil
- * In socket_is_still_usable(), use select()
- * and FD_ISSET() if poll() isn't available.
- *
- * Revision 1.34 2008/10/17 17:07:13 fabiankeil
- * Add preliminary timeout support.
- *
- * Revision 1.33 2008/10/16 16:34:21 fabiankeil
- * Fix two gcc44 warnings.
- *
- * Revision 1.32 2008/10/16 16:27:22 fabiankeil
- * Fix compiler warning.
- *
- * Revision 1.31 2008/10/16 07:31:11 fabiankeil
- * - Factor socket_is_still_usable() out of get_reusable_connection().
- * - If poll() isn't available, show a warning and assume the socket
- * is still usable.
- *
- * Revision 1.30 2008/10/13 17:31:03 fabiankeil
- * If a remembered connection is no longer usable and
- * has been marked closed, don't bother checking if the
- * destination matches.
- *
- * 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
- * Flush work-in-progress changes to keep outgoing connections
- * alive where possible. Incomplete and mostly #ifdef'd out.
- *
- * Revision 1.27 2008/09/27 15:05:51 fabiankeil
- * Return only once in forwarded_connect().
- *
- * Revision 1.26 2008/08/18 17:42:06 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
- * - Fix a compiler warning.
- * - Stop assuming that htonl(INADDR_NONE) equals INADDR_NONE.
- *
- * 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.
- *
- * Revision 1.18 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 1.16 2002/05/12 21:36:29 jongfoster
- * Correcting function comments
- *
- * Revision 1.15 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.14 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.13 2002/03/13 00:29:59 jongfoster
- * 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
- * Fixing int/size_t warnings
- *
- * 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.
- *
- * Revision 1.8 2001/09/13 20:10:12 jongfoster
- * Fixing missing #include under Windows
- *
- * Revision 1.7 2001/09/12 17:58:26 steudten
- *
- * add #include <string.h>
- *
- * Revision 1.6 2001/09/10 10:41:16 oes
- * Added #include in.h
- *
- * Revision 1.5 2001/07/29 18:47:57 jongfoster
- * Adding missing #include project.h
- *
- * Revision 1.4 2001/07/24 12:47:06 oes
- * Applied BeOS support update by Eugenia
- *
- * Revision 1.3 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.2 2001/06/07 23:11:38 jongfoster
- * Removing gateways[] list - no longer used.
- * Replacing function pointer in struct gateway with a directly
- * called function forwarded_connect(), which can do the common
- * 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.
- *
- * Revision 1.1.1.1 2001/05/15 13:58:54 oes
- * Initial import of version 2.9.3 source tree

- * Revision 1.12 2008/12/24 17:06:19 fabiankeil
- * Keep a thread around to timeout alive connections
- * even if no new requests are coming in.
- *
- * Revision 1.11 2008/11/13 09:08:42 fabiankeil
- * Add new config option: keep-alive-timeout.
- *
- * Revision 1.10 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 1.9 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 1.7 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.6 2002/03/25 22:12:45 oes
- * Added fix for undefined INADDR_NONE on Solaris by Bart Schelstraete
- *
- * Revision 1.5 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.4 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 1.3 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.
- *
- * Revision 1.2 2001/06/07 23:12:14 jongfoster
- * Removing gateways[] list - no longer used.
- * Replacing function pointer in struct gateway with a directly
- * called function forwarded_connect(), which can do the common
- * task of deciding whether to connect to the web server or HTTP
- * proxy.
- * Replacing struct gateway with struct forward_spec
- *
- * Revision 1.1.1.1 2001/05/15 13:58:54 oes
- * Initial import of version 2.9.3 source tree

- *
- * 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
- * Correcting compile warning with older gcc
- *
- * Revision 1.32 2002/03/31 17:18:59 jongfoster
- * Win32 only: Enabling STRICT to fix a VC++ compile warning.
- *
- * Revision 1.31 2002/03/29 03:33:13 david__schmidt
- * Fix Mac OSX compiler warnings
- *
- * Revision 1.30 2002/03/27 14:32:43 david__schmidt
- * More compiler warning message maintenance
- *
- * Revision 1.29 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.28 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.27 2002/03/13 00:27:05 jongfoster
- * 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

- * 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.

- * Revision 1.14 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 1.13 2008/03/21 11:13:59 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 1.12 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 1.9.2.1 2002/05/26 23:41:27 joergs
- * AmigaOS: Fixed wrong type of len in write_socket()
- *
- * Revision 1.9 2002/04/08 20:31:41 swa

- * Revision 1.8 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.7 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.6 2002/03/13 00:27:05 jongfoster
- * 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
- * Changed _FILENAME_H to FILENAME_H_INCLUDED.
- * Added forward declarations for needed structures.
- *
- * Revision 1.2 2001/06/07 23:06:09 jongfoster
- * The host parameter to connect_to() is now const.
- *
- * Revision 1.1.1.1 2001/05/15 13:58:54 oes
- * Initial import of version 2.9.3 source tree

- * on platforms where sizeof(int) < sizeof(long).
- *
- * Revision 1.230 2009/03/07 13:09:17 fabiankeil
- * Change csp->expected_content and_csp->expected_content_length from

- * Log unsigned values as such.
- *
- * Revision 1.227 2009/03/02 19:18:11 fabiankeil
- * Streamline parse_http_request()'s prototype. As
- * cparser pointed out it doesn't actually use csp.
- *
- * Revision 1.226 2009/03/01 18:28:24 fabiankeil
- * Help clang understand that we aren't dereferencing
- * NULL pointers here.

- * Revision 1.223 2009/02/09 21:21:16 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 1.222 2009/02/08 12:56:51 fabiankeil
- * Call initialize_mutexes() before init_log_module() again.
- * Broken since r220, might be the cause of Lee's #2579448.
- *
- * Revision 1.221 2009/02/06 18:02:58 fabiankeil
- * When dropping privileges, also give up membership in supplementary

- * Revision 1.214 2008/12/20 14:53:55 fabiankeil
- * Add config option socket-timeout to control the time

- *
- * Revision 1.211 2008/12/06 10:05:03 fabiankeil
- * Downgrade "Received x bytes while expecting y." message to
- * LOG_LEVEL_CONNECT as it doesn't necessarily indicate an error.
- *
- * Revision 1.210 2008/12/02 22:03:18 fabiankeil
- * Don't miscalculate byte_count if we don't get all the
- * server headers with one read_socket() call. With keep-alive
- * support enabled, this caused delays until the server closed
- * the connection.
- *
- * Revision 1.209 2008/11/27 09:44:04 fabiankeil
- * Cosmetics for the last commit: Don't watch out for
- * the last chunk if the content isn't chunk-encoded or
- * if we already determined the content length previously.
- *
- * Revision 1.208 2008/11/26 18:24:17 fabiankeil
- * Recognize that the server response is complete if the
- * last chunk is read together with the server headers.
- * Reported by Lee.
- *

- * Don't convert the client-header list to text until we need to.

- * Some more chat() cosmetics.
- *
- * Revision 1.205 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 1.204 2008/11/06 19:42:17 fabiankeil
- * Fix last-chunk detection hack to also apply
- * if buf[] contains nothing but the last-chunk.
- *
- * Revision 1.203 2008/11/06 18:34:35 fabiankeil
- * Factor receive_client_request() and
- * parse_client_request() out of chat().
- *
- * Revision 1.202 2008/11/02 18:40:34 fabiankeil
- * If we received a different amount of data than we expected,
- * log a warning and make sure the server socket isn't reused.
- *
- * Revision 1.201 2008/11/02 16:48:20 fabiankeil
- * Revert revision 1.195 and try again.

- * Remove two debug messages with LOG_LEVEL_INFO.
- *
- * Revision 1.198 2008/10/22 15:19:55 fabiankeil
- * Once More, With Feeling: if there is no logfile
- * because the user didn't specify one, we shouldn't
- * call init_error_log() after receiving SIGHUP either.
- *
- * Revision 1.197 2008/10/20 17:02:40 fabiankeil
- * If SIGHUP is received while we aren't running in daemon
- * mode, calling init_error_log() would be a mistake.
- *
- * Revision 1.196 2008/10/16 09:16:41 fabiankeil
- * - Fix two gcc44 conversion warnings.
- * - Don't bother logging the last five bytes
- * of the 0-chunk.
- *
- * Revision 1.195 2008/10/13 16:04:37 fabiankeil
- * Make sure we don't try to reuse tainted server sockets.
- *
- * Revision 1.194 2008/10/12 18:35:18 fabiankeil
- * The last commit was a bit too ambitious, apparently the content
- * length adjustment is only necessary if we aren't buffering.
- *
- * Revision 1.193 2008/10/12 15:57:35 fabiankeil
- * Fix content length calculation if we read headers
- * and the start of the body at once. Now that we have
- * FEATURE_CONNECTION_KEEP_ALIVE, it actually matters.
- *
- * Revision 1.192 2008/10/11 18:19:14 fabiankeil
- * Even more chat() cosmetics.
- *
- * Revision 1.191 2008/10/11 18:00:14 fabiankeil
- * Reformat some comments in chat().
- *
- * Revision 1.190 2008/10/11 14:58:00 fabiankeil
- * In case of chunk-encoded content, stop reading if
- * the buffer looks like it ends with the last chunk.
- *
- * Revision 1.189 2008/10/11 09:53:00 fabiankeil
- * Let server_response_is_complete() deal properly with
- * content that is neither buffered nor read all at once.
- *
- * Revision 1.188 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 1.184 2008/08/22 15:34:45 fabiankeil
- * - 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

- * Revision 1.182 2008/06/27 11:13:56 fabiankeil
- * Fix possible NULL-pointer dereference reported

- *
- * Revision 1.180 2008/05/21 15:26:32 fabiankeil
- * - Mark csp as immutable for send_crunch_response().
- * - Fix comment spelling.
- *
- * Revision 1.179 2008/05/20 20:13:32 fabiankeil
- * Factor update_server_headers() out of sed(), ditch the
- * first_run hack and make server_patterns_light static.
- *
- * Revision 1.178 2008/05/10 13:23:38 fabiankeil
- * Don't provide get_header() with the whole client state

- *
- * Revision 1.177 2008/05/10 11:51:12 fabiankeil

- * tell the client and log the problem.
- *
- * 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 1.165 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

- *
- * 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.

- *
- * 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

- * 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.

- * 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.

- * 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
- *
- * Revision 1.95 2006/08/03 02:46:41 david__schmidt

- * Added chroot ability, thanks to patch by Sviatoslav Sviridov
- *
- * Revision 1.92.2.6 2003/03/11 11:55:00 oes
- * Clean-up and extension of improvements for forked mode:

- * 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 1.88 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

- *
- * 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

- *
- * Revision 1.67 2002/03/04 18:18:57 oes

- * - 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 1.59 2001/12/13 14:07:18 oes
- * Fixed Bug: 503 error page now sent OK
- *
- * 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
- * Changing the tty-disconnection code to use setsid().
- *
- * Revision 1.56 2001/11/13 20:20:54 jongfoster

- *
- * Revision 1.53 2001/11/05 21:41:43 steudten

- *
- * 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 1.43 2001/10/02 15:32:13 oes
- * Moved generation of hdr
- *
- * Revision 1.42 2001/09/21 23:02:02 david__schmidt
- * Cleaning up 2 compiler warnings on OS/2.
- *
- * Revision 1.41 2001/09/16 17:05:14 jongfoster
- * Removing unused #include showarg.h
- *
- * Revision 1.40 2001/09/16 15:41:45 jongfoster
- * Fixing signed/unsigned comparison warning.
- *
- * Revision 1.39 2001/09/16 13:21:27 jongfoster
- * Changes to use new list functions.
- *
- * Revision 1.38 2001/09/16 13:01:46 jongfoster
- * Removing redundant function call that zeroed zalloc()'d memory.
- *
- * Revision 1.37 2001/09/10 11:12:24 oes
- * Deleted unused variable
- *
- * Revision 1.36 2001/09/10 10:56:15 oes
- * Silenced compiler warnings
- *
- * Revision 1.35 2001/07/31 14:44:22 oes
- * Deleted unused size parameter from filter_popups()
- *
- * 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.
- *
- * Revision 1.32 2001/07/29 18:47:05 jongfoster
- * Adding missing #include "loadcfg.h"
- *
- * Revision 1.31 2001/07/29 12:17:48 oes
- * 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
- *
- * Revision 1.26 2001/07/18 12:31:36 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 :

- * 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

- * Revisions :
- * $Log: list.c,v $
- * Revision 1.20 2007/05/14 16:56:07 fabiankeil
- * - Stop using strcpy().
- * - enlist_unique_header() now behaves as advertised
- * and checks for existing headers with the same name
- * but ignores the values.
- *
- * 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 gcc43 warning and enabled list_is_valid()'s loop
- * detection again. It was ineffective since the removal of
- * the arbitrary list length limit two years ago.
- *
- * Revision 1.17 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 1.15.2.2 2004/05/25 02:04:23 david__schmidt
- * Removed the "arbitrary" 1000 filter limit in file.c. See tracker #911950.
- *
- * Revision 1.15.2.1 2002/11/28 18:14:54 oes
- * Added unmap function that removes all items with a given
- * name from a map.
- *
- * Revision 1.15 2002/03/26 22:29:55 swa
- * we have a new homepage!
- *
- * Revision 1.14 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.13 2002/03/07 03:46:17 oes
- * 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.

- * Revisions :
- * $Log: list.h,v $
- * Revision 1.15 2007/04/17 18:14:06 fabiankeil
- * Add list_contains_item().
- *
- * 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 1.12.2.1 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
- * name change related issues
- *
- * 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.
- *
- * Revision 1.4 2001/06/29 13:30:37 oes
- * - 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 1.90 2009/03/07 17:58:02 fabiankeil

- *
- * Revision 1.89 2009/03/01 18:46:33 fabiankeil
- * - Help clang understand that we aren't

- *
- * Revision 1.88 2009/02/28 10:57:10 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

- * 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 1.65 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,

- * "allow-cgi-request-crunching".
- *
- * Revision 1.64 2007/05/21 10:44:08 fabiankeil
- * - Use strlcpy() instead of strcpy().

- * - Remove an unnecessary temporary memory allocation.
- * - Don't log anything to the console when running as
- * daemon and no errors occurred.

- *
- * 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

- *

- *
- * Revision 1.25 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.
- *

- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.19 2001/07/15 17:45:16 jongfoster

- *
- * Revision 1.14 2001/06/07 14:46:25 joergs
- * Missing make_path() added for re_filterfile.
- *
- * Revision 1.13 2001/06/05 22:33:54 jongfoster

- * Fixed minor memory leak.
- * Also now uses make_path to prepend the pathnames.
- *
- * Revision 1.12 2001/06/05 20:04:09 jongfoster
- * Now uses _snprintf() in place of snprintf() under Win32.
- *
- * Revision 1.11 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 1.10 2001/06/03 19:11:54 oes
- * introduced confdir option
- *
- * Revision 1.9 2001/06/01 20:06:24 jongfoster

- * wafer, add_header, user_agent, referer, from
- * Also globally replaced "permission" with "action".
- *
- * 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.)
- *
- * 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
- *

- * Revisions :
- * $Log: loadcfg.h,v $
- * Revision 1.13 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 1.11.2.1 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

- *
- * Revision 1.60 2007/03/20 15:16:34 fabiankeil

- * Fix typo.
- *
- * Revision 1.54 2006/09/07 10:22:20 fabiankeil
- * If too many trusted referrers are used,
- * print only one error message instead of logging
- * every single trusted referrer above the arbitrary
- * limit.
- *
- * Revision 1.53 2006/08/31 16:25:06 fabiankeil

- * solution after the next release.
- *

- *
- * Revision 1.50.2.1 2002/07/26 15:19:24 oes

- * Revision 1.36 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 1.35 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.

- * Moved ijb_isspace and ijb_tolower to project.h
- *
- * Revision 1.30 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 1.29 2001/10/23 21:38:53 jongfoster
- * Adding error-checking to create_url_spec()
- *

- * Revision 1.26 2001/09/22 14:05:22 jongfoster
- * Bugfix: Multiple escaped "#" characters in a configuration
- * file are now permitted.
- * Also removing 3 unused headers.
- *
- * Revision 1.25 2001/09/13 22:44:03 jongfoster
- * Adding {} to an if statement
- *
- * Revision 1.24 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 1.23 2001/07/20 15:51:54 oes
- * Fixed indentation of prepocessor commands
- *
- * Revision 1.22 2001/07/20 15:16:17 haroon
- * - per Guy's suggestion, added a while loop in sweep() to catch not just
- * the last inactive CSP but all other consecutive inactive CSPs after that
- * as well
- *
- * Revision 1.21 2001/07/18 17:26:24 oes
- * Changed to conform to new pcrs interface
- *
- * Revision 1.20 2001/07/17 13:07:01 oes

- * Various adaptions
- *
- * Revision 1.16 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.15 2001/06/07 23:14:14 jongfoster
- * Removing ACL and forward file loaders - these
- * files have been merged into the config file.
- * Cosmetic: Moving unloader funcs next to their
- * respective loader funcs
- *
- * Revision 1.14 2001/06/01 03:27:04 oes
- * 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

- * Provides the line in 2 alternative forms: raw and

- * - raw is the raw data read from the file. If the
- * line is not modified, then this should be written
- * to the new file.
- * - prefix is any comments and blank lines that were
- * read from the file. If the line is modified, then

- * by the modified data. (If this string is non-empty
- * then it will have a newline at the end).
- * - data is the actual data that will be parsed
- * further by appropriate routines.
- * On EOF, the 3 strings will all be set to NULL and
- * 0 will be returned.
- *
- * Parameters :
- * 1 : fp = File to read from
- * 2 : raw_out = destination for newly malloc'd pointer to
- * raw line data. May be NULL if you don't want it.
- * 3 : prefix_out = destination for newly malloc'd pointer to
- * comments. May be NULL if you don't want it.
- * 4 : data_out = destination for newly malloc'd pointer to
- * line data with comments and leading/trailing spaces
- * removed, and line continuation performed. May be

- * 5 : newline = Standard for newlines in the file.

- * Revisions :
- * $Log: loaders.h,v $
- * 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
- *

- * Changing the calls to strerr() to check HAVE_STRERR (which is defined
- * in config.h if appropriate) rather than the NO_STRERR macro.
- *

- * Revision 1.2 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
- *

- *
- * Function : string_join
- *
- * Description : Join two strings together. Frees BOTH the original
- * strings. If either or both input strings are NULL,
- * fails as if it had run out of memory.
- *
- * For comparison, string_append requires that the
- * second string is non-NULL, and doesn't free it.
- *
- * Rationale: Too often, we want to do
- * string_append(s, html_encode(s2)). That assert()s
- * if s2 is NULL or if html_encode() runs out of memory.
- * It also leaks memory. Proper checking is cumbersome.
- * The solution: string_join(s, html_encode(s2)) is safe,
- * and will free the memory allocated by html_encode().
- *
- * 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.
- * 2 : text_to_append = Text to be appended to old.
- *
- * 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, or if
- * *target_string or text_to_append is NULL. (In

- 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.

- * Revisions :
- * $Log: miscutil.h,v $
- * Revision 1.30 2008/04/17 14:53:31 fabiankeil
- * 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)
- *
- * Revision 1.21 2002/04/26 12:55:38 oes
- * New function string_toupper
- *
- * Revision 1.20 2002/03/26 22:29:55 swa

- * 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

- * size_t to unsigned long long to reduce the likelihood of integer
- * overflows that would let us close the connection prematurely.

- *
- * 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

- * lose all but the last one.
- *

- * 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
- * - A few style fixes.

- * 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.
- *
- * Revision 1.133 2008/05/21 15:50:47 fabiankeil

- * Wrap memmove() calls in string_move()
- * to document the purpose in one place.

- * Normalize linear header white space.
- *
- * Revision 1.128 2008/05/16 16:39:03 fabiankeil

- * merge them to a single line before parsing them.
- *
- * Revision 1.127 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 1.126 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

- *
- * 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

- * Fix a crash on mingw32 with some Last Modified times in the future.
- *
- * Revision 1.115 2007/11/02 16:52:50 fabiankeil

- * 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

- * 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.
- *
- * Revision 1.106 2007/08/18 14:30:32 fabiankeil
- * Let content-type-overwrite{} honour force-text-mode again.

- *
- * Revision 1.104 2007/07/14 07:38:19 fabiankeil

- *
- * Revision 1.101 2007/05/14 10:16:41 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.

- *
- * Revision 1.90 2007/02/08 19:12:35 fabiankeil
- * Don't run server_content_length() the first time

- *
- * Revision 1.89 2007/02/07 16:52:11 fabiankeil
- * Fix log messages regarding the cookie time format

- * Revision 1.88 2007/02/07 11:27:12 fabiankeil
- * - Let decompress_iob()

- *
- * 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
- * OS/2 compilation compatibility fixups

- *
- * Revision 1.61 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 1.58 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 1.56.2.10 2006/01/21 16:16:08 david__schmidt
- * Thanks to Edward Carrel for his patch to modernize OSX'spthreads support. See bug #1409623.
- *
- * Revision 1.56.2.9 2004/10/03 12:53:45 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 1.56.2.8 2003/07/11 13:21:25 oes
- * Excluded text/plain objects 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.
- *
- * Revision 1.56.2.7 2003/05/06 12:07:26 oes
- * Fixed bug #729900: Suspicious HOST: headers are now killed and regenerated if necessary
- *
- * Revision 1.56.2.6 2003/04/14 21:28:30 oes
- * Completing the previous change
- *
- * Revision 1.56.2.5 2003/04/14 12:08:16 oes
- * Added temporary workaround for bug in PHP < 4.2.3
- *
- * Revision 1.56.2.4 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 1.56.2.3 2002/11/10 04:20:02 hal9
- * Fix typo: supressed -> suppressed
- *
- * Revision 1.56.2.2 2002/09/25 14:59:53 oes
- * Improved cookie logging
- *
- * Revision 1.56.2.1 2002/09/25 14:52:45 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 1.56 2002/05/12 15:34:22 jongfoster
- * Fixing typo in a comment
- *
- * Revision 1.55 2002/05/08 16:01:07 oes
- * Optimized add_to_iob:
- * - Use realloc instead of malloc(), memcpy(), free()
- * - Expand to powers of two if possible, to get
- * O(log n) reallocs instead of O(n).
- * - Moved check for buffer limit here from chat
- * - Report failure via returncode
- *

- * Killing warnings

- * More verbose logging
- *
- * Revision 1.49 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 1.48 2002/03/07 03:46:53 oes
- * Fixed compiler warnings etc
- *
- * Revision 1.47 2002/02/20 23:15:13 jongfoster
- * Parsing functions now handle out-of-memory gracefully by returning
- * an error code.
- *
- * Revision 1.46 2002/01/17 21:03:47 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Revision 1.45 2002/01/09 14:33:03 oes
- * Added support for localtime_r.
- *
- * Revision 1.44 2001/12/14 01:22:54 steudten
- * Remove 'user:pass@' from 'proto://user:pass@host' for the
- * new added header 'Host: ..'. (See Req ID 491818)
- *
- * Revision 1.43 2001/11/23 00:26:38 jongfoster
- * Fixing two really stupid errors in my previous commit

- * ctype.h is needed in Windows, too.
- *
- * Revision 1.39 2001/10/26 17:40:04 oes
- * Introduced get_header_value()
- * Removed http->user_agent, csp->referrer and csp->accept_types
- * Removed client_accept()
- *
- * Revision 1.38 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 1.37 2001/10/23 21:36:02 jongfoster
- * Documenting sed()'s error behaviou (doc change only)
- *
- * Revision 1.36 2001/10/13 12:51:51 joergs
- * 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
- * a HTTP/1.1 server/proxy).
- *
- * Revision 1.35 2001/10/09 22:39:21 jongfoster
- * assert.h is also required under Win32, so moving out of #ifndef _WIN32
- * block.
- *
- * Revision 1.34 2001/10/07 18:50:55 oes
- * Added server_content_encoding, renamed server_transfer_encoding
- *
- * Revision 1.33 2001/10/07 18:04:49 oes
- * Changed server_http11 to server_http and its pattern to "HTTP".
- * Additional functionality: it now saves the HTTP status into
- * csp->http->status and sets CT_TABOO for Status 206 (partial range)
- *
- * 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)
- *
- * Revision 1.31 2001/10/05 14:25:02 oes
- * Crumble Keep-Alive from Server
- *
- * Revision 1.30 2001/09/29 12:56:03 joergs

- * Revision 1.24 2001/09/13 23:05:50 jongfoster
- * Changing the string paramater to the header parsers a "const".
- *
- * Revision 1.23 2001/09/12 18:08:19 steudten
- *
- * In parse_http_request() header rewriting miss the host value, so
- * from http://www.mydomain.com the result was just " / " not
- * http://www.mydomain.com/ in case we forward.
- *
- * Revision 1.22 2001/09/10 10:58:53 oes
- * Silenced compiler warnings

- * deleted const struct interceptors
- *
- * Revision 1.14 2001/06/01 18:49:17 jongfoster
- * Replaced "list_share" with "list" - the tiny memory gain was not
- * worth the extra complexity.
- *
- * Revision 1.13 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 1.12 2001/05/31 17:33:13 oes
- *
- * CRLF -> LF
- *
- * Revision 1.11 2001/05/29 20:11:19 joergs
- * '/ * inside comment' warning removed.
- *
- * 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 2001/05/28 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
- *

- * Revision 1.47 2008/05/21 20:12:11 fabiankeil
- * The whole point of strclean() is to modify the

- * 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.
- *

- * Remove the prototypes for functions that are only
- * used in parsers.c and thus should be static.

- * 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(),

- *
- * Revision 1.36 2007/03/05 13:25:32 fabiankeil
- * - Cosmetical changes for LOG_LEVEL_RE_FILTER messages.

- *
- * Revision 1.35 2007/01/01 19:36:37 fabiankeil

- *
- * 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{}.

- * 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
- *

-# dll.mk - auxilary Makefile to easy build dll's for mingw32 target
-# ver. 0.6 of 1999-03-25
-#
-# 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
-# libstuff.dll.a: $(OBJECTS) stuff.def
-# stuff.def: $(OBJECTS)
-#
-# Steps separated, pre-provided .def, link with user32
-#
-# DLL_LDLIBS=-luser32
-# stuff.dll: $(OBJECTS)
-# libstuff.dll.a: $(OBJECTS)

-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
-contributed by Paul.Sokolovsky(a)technologist.com. These environments are
-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
- linked pgrep and pcretest. If you have /bin/sh, run RunTest (three
- main test go ok, locale not supported).

-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
-than in characters.
-
-The following UTF-8 features of Perl 5.6 are not implemented:
-
-1. The escape sequence \\C to match a single byte.
-
-2. The use of Unicode tables and properties and escapes \\p, \\P, and \\X.

-<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>

-<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
- 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.
-
-
-
-MULTI-THREADING
- The PCRE functions can be used in multi-threading
-
-
-
-
-
-SunOS 5.8 Last change: 2
-
-
-
- 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.
-.TP
-\fB-c\fR
-Do not print individual lines; instead just print a count of the number of
-lines that would otherwise have been printed. If several files are given, a
-count is printed for each of them.
-.TP
-\fB-h\fR
-Suppress printing of filenames when searching multiple files.
-.TP
-\fB-i\fR
-Ignore upper/lower case distinctions during comparisons.
-.TP
-\fB-l\fR
-Instead of printing lines from the files, just print the names of the files
-containing lines that would have been printed. Each file name is printed
-once, on a separate line.
-.TP
-\fB-n\fR
-Precede each line by its line number in the file.
-.TP
-\fB-s\fR
-Work silently, that is, display nothing except error messages.
-The exit status indicates whether any matches were found.
-.TP
-\fB-v\fR
-Invert the sense of the match, so that lines which do \fInot\fR match the
-pattern are now the ones that are found.
-.TP
-\fB-x\fR
-Force the pattern to be anchored (it must start matching at the beginning of
-the line) and in addition, require it to match the entire line. This is
-equivalent to having ^ and $ characters at the start and end of each
-alternative branch in the regular expression.
-
-
-.SH SEE ALSO
-\fBpcre(3)\fR, Perl 5 documentation
-
-
-.SH DIAGNOSTICS
-Exit status is 0 if any matches were found, 1 if no matches were found, and 2
-for syntax errors or inacessible files (even if matches were found).

-NAME
- pcregrep - a grep with Perl-compatible regular expressions.
-
-
-
-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.
-
- -l Instead of printing lines from the files, just
- 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
- error messages. The exit status indicates whether
- any matches were found.
-
- -v Invert the sense of the match, so that lines which
- do not match the pattern are now the ones that are
- found.
-
- -x Force the pattern to be anchored (it must start
- matching at the beginning of the line) and in
- addition, require it to match the entire line.
- This is equivalent to having ^ and $ characters at
- the start and end of each alternative branch in
- the regular expression.

-pcreposix - POSIX API for Perl-compatible regular expressions.

-.PP
-.br
-.B void regfree(regex_t *\fIpreg\fR);
-
-
-.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.

-NAME
- pcreposix - POSIX API for Perl-compatible regular expres-
- sions.
-
-
-
-SYNOPSIS
- #include <pcreposix.h>
-
- int regcomp(regex_t *preg, const char *pattern,
- int cflags);
-
- int regexec(regex_t *preg, const char *string,
- size_t nmatch, regmatch_t pmatch[], int eflags);
-
- size_t regerror(int errcode, const regex_t *preg,
- char *errbuf, size_t errbuf_size);
-
- void regfree(regex_t *preg);
-
-
-
-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.

-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.
