Reported by cyberpatrol. -- The Connection: keep-alive code properly deals with files - larger than 2GB. Previously the connection was closed too - early. -- The content length for files above 2GB is logged correctly. -- The user-manual directive on the show-status page links to - the documentation location specified with the directive, - not to the Privoxy website. -- When running in daemon mode, Privoxy doesn't log anything - to the console unless there are errors before the logfile - has been opened. -- The show-status page prints warnings about invalid directives - on the same line as the directives themselves. -- Fixed several justified (but harmless) compiler warnings, - mostly on 64 bit platforms. -- The mingw32 version explicitly requests the default charset - to prevent display problems with some fonts available on more - recent Windows versions. Patch by Burberry. -- The mingw32 version uses the Privoxy icon in the alt-tab - windows. Patch by Burberry. -- The timestamp and the thread id is omitted in the "Fatal error" - message box on mingw32. -- Fixed two related mingw32-only buffer overflows. Triggering - them required control over the configuration file, therefore - this isn't seen as a security issue. -- In verbose mode, or if the new option --show-skipped-tests - is used, Privoxy-Regression-Test logs skipped tests and the - skip reason. - -*** Version 3.0.11 *** - -- On most platforms, outgoing connections can be kept alive and - reused if the server supports it. Whether or not this improves - things depends on the connection. -- When dropping privileges, membership in supplementary groups - is given up as well. Not doing that can lead to Privoxy running - with more rights than necessary and violates the principle of - least privilege. Users of the --user option are advised to update. - Thanks to Matthias Drochner for reporting the problem, - providing the initial patch and testing the final version. -- Passing invalid users or groups with the --user option - didn't lead to program exit. Regression introduced in 3.0.7. -- The match all section has been moved from default.action - to a new file called match-all.action. As a result the - default.action no longer needs to be touched by the user - and can be safely overwritten by updates. -- The standard.action file has been removed. Its content - is now part of the default.action file. -- In some situations the logged content length was slightly too low. -- Crunched requests are logged with their own log level. - If you used "debug 1" in the past, you'll probably want - to additionally enable "debug 1024", otherwise only passed - requests will be logged. If you only care about crunched - requests, simply replace "debug 1" with "debug 1024". -- The crunch reason has been moved to the beginning of the - crunch message. For HTTP URLs, the protocol is logged as well. -- Log messages are shortened by printing the thread id on its - own (as opposed to putting it inside the string "Privoxy()"). -- The config option socket-timeout has been added to control - the time Privoxy waits for data to arrive on a socket. -- Support for remote toggling is controlled by the configure - option --disable-toggle only. In previous versions it also - depended on the action editor and thus configuring with the - --disable-editor option would disable remote toggling support - as well. -- Requests with invalid HTTP versions are rejected. -- The template symbol @date@ can be used to include a date(1)-like - time string. Initial patch submitted by Endre Szabo. -- Responses from shoutcast servers are accepted again. - Problem reported and fix suggested by Stefan. -- The hide-forwarded-for-headers action has been replaced with - the change-x-forwarded-for{} action which can also be used to - add X-Forwarded-For headers. The latter functionality already - existed in Privoxy versions prior to 3.0.7 but has been removed - as it was often used unintentionally (by not using the - hide-forwarded-for-headers action). -- A "clear log" view option was added to the mingw32 version - to clear out all of the lines in the Privoxy log window. - Based on a patch submitted by T Ford. -- The mingw32 version uses "critical sections" now, which prevents - log message corruption under load. As a side effect, the - "no thread-safe PRNG" warning could be removed as well. -- The mingw32 version's task bar icon is crossed out and - the color changed to gray if Privoxy is toggled off. - -*** Version 3.0.10 *** - -- Ordinary configuration file changes no longer cause program - termination on OS/2 if the name of the logfile hasn't been - changed as well. This regression probably crept in with the - logging improvements in 3.0.7. Reported by Maynard. -- The img-reorder filter is less likely to mess up JavaScript code in - img tags. Problem and solution reported by Glenn Washburn in #2014552. -- The source tar ball now includes Privoxy-Log-Parser, - a syntax-highlighter for Privoxy logs. For fancy screenshots see: - http://www.fabiankeil.de/sourcecode/privoxy-log-parser/ - Documentation is available through perldoc(1). - -*** Version 3.0.9 Beta *** - -- Added SOCKS5 support (with address resolution done by - the SOCKS5 server). Patch provided by Eric M. Hopper. -- The "blocked" CGI pages include a block reason that was - provided as argument to the last-applying block action. -- If enable-edit-actions is disabled (the default since 3.0.7 beta) - the show-status page hides the edit buttons and explains why. - Previously the user would get the "this feature has been disabled" - message after using the edit button. -- Forbidden CONNECT requests are treated like blocks by default. - The now-pointless treat-forbidden-connects-like-blocks action - has been removed. -- Not enabling limit-connect now allows CONNECT requests to all ports. - In previous versions it would only allow CONNECT requests to port 443. - Use +limit-connect{443} if you think you need the old default behaviour. -- The CGI editor gets turned off after three edit requests with invalid - file modification timestamps. This makes life harder for attackers - who can leverage browser bugs to send fake Referers and intend to - brute-force edit URLs. -- Action settings for multiple patterns in the same section are - shared in memory. As a result these sections take up less space - (and are loaded slightly faster). Problem reported by Franz Schwartau. -- Linear white space in HTTP headers will be normalized to single - spaces before parsing the header's content, headers split across - multiple lines get merged first. This should prevent problems like: - * letting the session-cookies-only action slip - some Cookies through unmodified, - * only suppressing the first line of a header, - thus creating an invalid one, and - * to incorrectly block headers with valid timestamps - that weren't properly recognized. - Headers that could trigger these problems are unlikely to appear - in "normal" web traffic, but could be intentionally generated to - fool some of Privoxy's header parsers. -- Host information is gathered outside the main thread so it's less - likely to delay other incoming connections if the host is misconfigured. -- New config option "hostname" to use a hostname other than - the one returned by the operating system. Useful to speed-up responses - for CGI requests on misconfigured systems. Requested by Max Khon. -- The CGI editor supports the "disable all filters of this type" - directives "-client-header-filter", "-server-header-filter", - "-client-header-tagger" and "-server-header-tagger". -- Fixed false-positives with the link-by-url filter and URLs that - contain the pattern "/jump/". -- The less-download-windows filter no longer messes - "Content-Type: application/x-shockwave-flash" headers up. -- In the show-url-info page's "Final results" section active and - inactive actions are listed separately. Patch provided by Lee. -- The GNUmakefile supports the DESTDIR variable. Patch for - the install target submitted by Radoslaw Zielinski. -- Embedding the content of configuration files in the show-status - page is significantly faster now. For a largish action file (1 MB) - a speedup of about 2450 times has been measured. This is mostly - interesting if you are using large action files or regularly use - Privoxy-Regression-Test while running Privoxy through Valgrind, - for stock configuration files it doesn't really matter. -- If zlib support is unavailable and there are content - filters active but the prevent-compression action is disabled, - the show-url-info page includes a warning that compression - might prevent filtering. -- The show-url-info page provides an OpenSearch Description that - allows to access the page through browser search plugins. -- Custom client-header filters that rewrite the request line - incorrectly no longer cause Privoxy to crash. Reported by din_a4. -- The obsolete kill-popups action has been removed as the - PCRS-based popup filters can do the same and are slightly - less unreliable. -- The inspect-jpegs action has been removed. -- The send-wafer and send-vanilla-wafer actions have been removed. - They weren't particular useful and their behaviour could be emulated - with add-header anyway. -- Privoxy-Regression-Test has been significantly improved. -- Most sections in the default.action file contain tests for - Privoxy-Regression-Test to verify that they are working as intended. -- Parts of Privoxy have been refactored to increase maintainability. -- Building with zlib (if available) is done by default. - -*** Version 3.0.8 *** - -- Fixed a small memory leak when listen-address only specifies the port. -- The source tar balls now include Privoxy-Regression-Test which - (upon other things) can be used to automatically detect some - packaging problems. Packagers are welcome to give it a try. -- Reverted a change in 3.0.7 that caused path patterns to be checked - even if the host pattern match already failed. While this doesn't - noticeable affect the performance, it makes it less likely to run - out of stack space with overly-complex path patterns the user might - have added. -- Updated the msn, yahoo and google filters to work as advertised again. -- The warning message shown by the show-status CGI page is easier to - understand. Previously it wasn't clear that the error message - is shown below the invalid directive. (Reported by Lee) -- When regenerating Content-Disposition headers the more common - spelling is used for the name. Previously it was written without caps. -- Less confusing log message if the content type isn't overwritten - because force-text-type wasn't used but the old type doesn't look - like content that would be filtered normally. -- Better log messages if the user tries to execute filters that - don't exist. -- Treat the non-standard Request-Range headers like standard range - headers and suppress them if content filtering is enabled. -- Prevent the log messages for CONNECT requests to unacceptable - ports from printing the limit-connect argument as [null] if - limit-connect hasn't been explicitly enabled. -- Don't disable the mingw32 log window if the logfile directive - isn't used. While it was an intentional change in 3.0.7 at least - one user perceived it as a regression and the same effect can - be achieved by disabling all debug directives. -- Fixed two minor problems related to the win32 build process: a css - file was not being in the installer and the trustfile comment in the - config.txt referenced a nonexisting file -- Minor documentation fixes. - -*** Version 3.0.7 Beta *** - -- Added zlib support to filter content with gzip and deflate - encoding. (Patch provided by Wil Mahan) -- Dedicated filters and actions are used for header filtering. - "filter-client-headers" and "filter-client-headers" are no longer - supported, use server-header-filter{} and client-header-filter{} - instead. -- Tags can be used to change actions based on HTTP headers. -- New server-header filter: less-download-windows. -- New client-header taggers: css-requests, image-requests, - client-ip-address, http-method, allow-post, complete-url, - user-agent and privoxy-control. -- New server-header taggers: content-type and privoxy-control. -- The forward-override{} action allows to change the forwarding - settings through the action files, for example based on client - headers like the User-Agent, or the request origin. -- Socks errors are no longer handled by the CGI page for - DNS resolution failures. -- CGI pages use favicons to signal whether they are error - or control pages. This is useful if you rely heavily on - browser tabs. -- The show-url-info CGI page shows the forwarding settings. -- "Crunch!" log messages (used when Privoxy answers requests - by itself) now also contain the reason. -- Allow to rewrite the request destination behind the client's back. -- Fix socks requests on big-endian platforms. Patch provided by Song Weijia. -- Fixes possible deadlocks and crashes on OpenBSD. - Patch provided by Ralf Horstmann. -- The CGI action editor allows to edit actionfiles with previously - forbidden characters like dots. -- New trust entries are saved with a comment that contains the - trusted referring URL (Suggested by Daniel Griscom). -- Filter descriptions are HTML encoded automatically. -- New config option "split-large-forms" to work - around a browser bug that caused IE6 and IE7 to ignore - the Submit button on the edit-actions-for-url CGI page. -- New config option "allow-cgi-request-crunching" to allow - requests for Privoxy's CGI pages to be blocked, redirected - or (un)trusted like ordinary requests. -- Empty filter files no longer interrupt the filtering process - prematurely and are correctly listed on the show-status CGI page. -- New config option "accept-intercepted-requests" to combine - Privoxy with any packet filter to build an intercepting proxy - for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set). -- fast-redirects{} catch redirects to https URLs as well. -- redirect{s@foo@bar@} can be used to redirect to a rewritten - version of the original URL. -- Trap unsupported gopher proxy requests. -- Fixed a bug in the User Manual delivery on Windows - (mingw32 only). Images now show up correctly and HTML - pages are no longer padded with garbage data. -- Fixed several minor memory leaks, most of them discovered with Valgrind. -- Only unlink the pidfile if it's actually used. -- Retries after connection problems with forced requests - aren't blocked again. -- On Unix SIGABRT causes a core dump as expected and is no - longer treated as normal shutdown signal. -- The "access denied" CGI page is more descriptive and - allows retries to circumvent the referrer check. -- Updated PCRS to handle unexpected PCRE errors properly. - Fixed crashes that could occur if Privoxy was build - with external PCRE versions newer than Privoxy's internal - one. (Reported by Chung-chieh Shan) -- Fixed crashes with null bytes in PCRS replacement strings - (Patch provided by Felix Gröbert). -- Fixed crashes with header time randomization on mingw32. -- The CGI style sheet is no longer delivered if the referring - page isn't a Privoxy CGI page. This prevents a JavaScript-based - Privoxy detection "attack". Note that detecting Privoxy is - still possible through other ways and Privoxy was never intended - to be invisible anyway. -- Added support for AmigaOS 4, fixed build for AmigaOS 3.x. -- The show-url-info CGI page displays a warning if Privoxy - is currently toggled off. -- The show-status CGI page suppresses the edit button - for action files if Privoxy has no write access. -- Most CGI error pages react properly to HEAD requests. -- Requests with RFC 3253 HTTP methods (used by Subversion) - are accepted. (Patch provided by Petr Kadlec) -- New config option "templdir" to change the location - of the CGI templates to make sure customized templates - aren't "updated". -- Better handling of "HTTP/1.1 100 Continue" responses. -- The background of the PNG pattern is transparent. -- Fixed XML syntax errors caused by banners-by-size and banners-by-url. -- Fixed crashes and possible action file corruptions - when lines containing hashes are written through the CGI editor. -- Supports dynamic filters which can contain variables. -- Supports tags to change the actions based on client or server headers. -- Incorrect actions are logged before program termination. -- The "actionsfile" syntax in the configuration file is consistent - with the rest of the configuration options and requires the - whole file name. This is an incompatible change, if you use - an old configuration file you might have to append ".action" - to your "actionsfile" directives. -- With the configuration file option "enforce-blocks" the - "go there anyway" mechanism can be disabled without recompiling - Privoxy. -- More precise error messages in case of incorrect acl syntax. -- Logs a warning if filtering is enabled but impossible due - to lack of zlib support or use of the prevent-compression action. -- Less noisy handling of Cookie:" and "Connection:" headers. -- Improved error messages in case of connection problems. -- Fix a command-line-parsing bug that was introduced before 3.0.5 - beta and caused Privoxy to treat the last argument as configuration - file if no configuration file was specified. -- Treat unknown command line options as fatal errors instead - of silently ignoring them. -- Use string functions with length checks more often. -- Don't log CONNECT requests twice. -- Allow to log the source address for ACL-related connection drops. -- Don't ignore applying filters if the server didn't - specify a Content-Type. Bug reported by Amuro Namie. -- Rejected CONNECT requests are logged with log level info - (enabled by default) and the reason for the block. -- New command line option "--pre-chroot-nslookup hostname" to - intialize the resolver library before chroot'ing. On some systems this - reduces the number of files that must be copied into the chroot tree. - (Patch provided by Stephen Gildea) -- Fix a long-standing memory corruption bug that could cause - Privoxy to overwrite a single byte in memory it didn't explicitly - allocate (but that probably was allocated anyway due to bucket size). -- Send template-based CGI pages as HTTP/1.1 unless the client - asked for HTTP/1.0. -- Let the first line in connection established responses - end in \r\n as required by RFC1945. Reported by Bert van Leeuwen. -- If no log file has been specified, disable logging instead of logging - to stderr. -- Don't block stderr when in daemon mode. -- Ignore missing zero-chunks when filtering chunk-encoded content. - Earlier Privoxy versions would buffer and then forward the content - unmodified which caused some browsers to simply show empty pages. -- Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB. -- The code to add X-Forwarded-For headers when the hide-forwarded-for-headers - action isn't being used has been removed. -- Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE. - Reported by Lee. -- Minor code clean-ups, filter and action file updates. - (Some of them reported by Davide Alberani, Markus Elfring, - Stefan Huehner and Adam Piggott) - -*** Version 3.0.6 *** - -- New content filters: no-ping, google, msn, yahoo and blogspot. -- New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html - and hide-tor-exit-notation. -- The special header "X-Filter: No" now disables header filtering as well. -- Improved the filters img-reorder, js-annoyances, webbugs, - banners-by-size, banners-by-link and ie-exploits to make them - less likely to break anything. -- Removed outdated URL patterns in default.action and added new ones. -- Added redirection from http://p.p/user-manual to http://p.p/user-manual/ -- Changed webinterface default values for hide-user-agent, hide-referrer - and set-image-blocker. - -*** Version 3.0.5 Beta *** - -- Windows version can be installed/started as a service. -- Windows icon stays blue when Privoxy is idle, green when busy. -- Integrated Fabian Keil's extensive patch. See: - http://www.fabiankeil.de/sourcecode/privoxy/. Includes the - following new or significantly improved actions (among many - other improvements): - - content-type-overwrite{} - crunch-client-header{string} - crunch-if-none-match - crunch-server-header{string} - fast-redirects{check-decoded-url} - filter-client-headers - filter-server-headers - force-text-mode - handle-as-empty-document - hide-accept-language{} - hide-content-disposition{} - hide-if-modified-since - hide-referrer{conditional-block} - overwrite-last-modified{} - redirect{URL} - treat-forbidden-connects-like-blocks - -- Standard-compliant clients are prevented from displaying cached - copies of Privoxy's error messages after the cause of the problem - has gone. -- Improved DNS error handling. -- Multiple filter files can now be specified in config. -- Added jpeg filtering to defend against MS jpeg vulnerability MS04-028 - with the new inspect-jpegs action. -- Removed the "arbitrary" 1000 filter limit - addresses tracker #911950 -- Thanks to Jindrich Makovicka for a race condition fix for the log - file. The race condition remains for non-pthread implementations. - Reference patch #1175720. Various other logging enhancements. -- A pile of assorted bug fixes, memory leaks, enhancements, etc. -- Moved Actions file reporting mechanism to SF tracker. -- Two new options for config: enable-remote-http-toggle and - forwarded-connect-retries. -- Trap unsupported FTP requests. -- Let text/xml be filtered. -- Numerous updates to default.action -- Increase the compiled in limit of trusted referrers from 64 to 512 - (for trustfile users). - -*** Version 3.0.3 *** - -- Fixed yet another two memory leaks. Process growth seems stopped now. -- Further tightened security against malicious toggle-off links. -- Excluded text/plain MIME types from filtering. This fixes a - couple of client-crashing, download corruption and - Privoxy performance issues, whose root cause lies in - web servers labelling content of unknown type as text/plain. -- Assorted fixes for POSIX compliance, signal handling, graceful - termination, compiler warnings, OSX support, Win32 systray, - error logging, hostname wildcards, correct detection of NetBSD. -- Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs - including the notorious "blank page" problem. -- Various filter improvements; most notably the unsolicited-popups - filter became less destructive -- Major revamp of the actions file - -*** Version 3.0.2 *** - -- Fixed two memory leaks, one serious -- Fixed bug in pcrs which could cause crashes with user-defined filters -- Fixed bug in domain name matching -- Assorted small fixes (Win32 menu, CGI URL editor, ..) -- Added basic support for the OPTIONS and TRACE http methods -- Added workaround for Bug in Mac OSX that made Privoxy crash occasionally -- Refined the default action file through >400 items of user feedback -- Filter changes: - - Assorted refinements, optimizations and fixes in the js-annoyances, - img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags, - html-annoyances, content-cookies and fun filters - - Replaced filter "popups" by choice between two modes: - - "unsolicited-popups" tries to catch only the unsolicited ones - - "all-popups" tries to kill them all (as before) - - New filter "tiny-textforms" Help those tiny or hard-wrap textareas. - - New filter "jumping-windows" that prevents windows from resizing - and moving themselves - - New filter "demoronizer" which fixes MS's abuse of std charsets - (common cases anyway). - - Replaced "nimda" with more general "ie-exploits" filter in which - all filters for exploits shall be collected -- Improved cookie logging -- Rewrote make install target. Added uninstall and install-strip - targets. -- Fixed a potential (application-level, NOT OS-level!) security - problem involving remote toggling and action file manipulation - by mailicious websites. -- Added ability to chroot (thanks to Sviatoslav Sviridov) -- Added more action aliases for prehistoric action names -- Add Slackware support to Makefile. - -*** Version 3.0 *** - -- Fixed Windows startmenu items, log window and tray icon menus. -- Added warning for bogus install target -- Added quicktime-kioskmode filter and improved frameset-borders -- Updated default.action based on latest feedback -- New PDF doc build process -- Add a user contrib module to cvs: - http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/ijbswa/contrib/ - -*** Version 2.9.18 *** - -- Added workaround for IE bug that broke CGI interface -- Bugfix: String actions now reliably editable through CGI interface -- Three filters fixed (again!) -- Assorted small fixes and doc enhancements - -*** Version 2.9.16 *** - -- Major revamp of default.action to get rid of years of cruft. -- Same for default.filter -- Re-design and major improvements to the CGI editor interface. -- Address spurious 'out of memory' error due to incorrect file permissions. -- Impose buffer limits while reading client and server headers. -- Better memory and CPU optimization. -- Add Conectiva Linux package. -- user-manual directive added to config for help links from within CGI - editor. -- Multiple actions files can now be specified in config. -- Actions files are changed to: default.action, standard.action, and - user.action. user.action is for personal/local configuration. -- The usual many small and miscellaneous bug and security fixes. - -*** Version 2.9.14 Beta *** - -- Fix Solaris compile problem (gateway.h and filters.h) -- Makefile fixes for Solaris, FreeBSD (?) -- Fix build failure where certain features were disabled. -- 'blocked-compact' template is removed. Various CGI improvements, - including an adaptive 'blocked' template. -- Various tweaks for actions file to get ready for stable 3.0 -- Included a 'Bookmarklet' and PHP scripts for reporting actions file - problems via web interface at privoxy.org. Accessed via internal CGIs. -- Include cgi-style.css for templates. -- #include mechansim for common text in templates -- Various other minor fixes. - -*** Version 2.9.13 Beta *** - -- *NEWS*: The project has been renamed to Privoxy! The new name is - reflected throughout (file locations, etc). -- ijb.action is now default.action. re_filterfile is now - default.filter. -- http://i.j.b/ is now http://p.p/ -- The 'logo' option for replacing ad iamges is removed now. 'Pattern' - (checkerboard) is now the default. -- RPM spec file make over. - - -*** Version 2.9.12 Beta *** - -- **READ**: The default listening PORT is NOW 8118!!! Changed from - 8000 due to conflict with NAS (Network Audio Server, whatever that - is.) -- More CGI actions editor fixes and improvements. -- Win32 command line fix ups. -- re_filterfile now has modular sections that can be activated on a - per site basis. Some new goodies there too. -- +filter now takes arguments to match FILTER sections in re_filterfile - for even more flexibility. -- Added a new image blocker option: +image-blocker{pattern}, which - displays a checkerboard patthern and scales better than the logo. -- PNG images will be used in place of GIF for JB built-in images - if configured with --enable-no-gif. -- Clean up compiler warnings (mostly). -- Improved handling of failed DNS lookups & diagnostics for failed bind - to listen socket -- 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 - - - ----------------------------------------------------------------------- -Copyright : Written by and Copyright (C) 2001-2008 the SourceForge - Privoxy team. http://www.privoxy.org/ - - Based on the Internet Junkbuster originally written - by and Copyright (C) 1997 Anonymous Coders and - Junkbusters Corporation. http://www.junkbusters.com/ - - 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.

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. - diff --git a/external/privoxy/LICENSE b/external/privoxy/LICENSE deleted file mode 100644 index d511905..0000000 --- a/external/privoxy/LICENSE +++ /dev/null @@ -1,339 +0,0 @@ - GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc., - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10.

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. - -------------------------------------------------------------------------------- - -6.3. Request New Features - -You are welcome to submit ideas on new features or other proposals for -improvement through our feature request tracker at http://sourceforge.net/ -tracker/?atid=361118&group_id=11118. - -------------------------------------------------------------------------------- - -6.4. Other - -For any other issues, feel free to use the mailing lists. Technically -interested users and people who wish to contribute to the project are also -welcome on the developers list!

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.

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.

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

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.

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.

(i.e. ijb-send-banner uses this) -dnl - Implemented show-url-info interceptor.

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. -# -############################################################################# - -############################################################################# -# Settings -- Don't change. -############################################################################# -{{settings}} -############################################################################# -#MASTER# COMMENT: The minimum Privoxy version: -for-privoxy-version=3.0.11 - -############################################################################# -# Aliases -############################################################################# -{{alias}} -############################################################################# -# -# You can define a short form for a list of permissions - e.g., instead -# of "-crunch-incoming-cookies -crunch-outgoing-cookies -filter -fast-redirects", -# you can just write "shop".

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.

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 - CHARGE,</a> THERE IS NO WARRANTY FOR THE PROGRAM, TO THE - EXTENT PERMITTED BY APPLICABLE LAW.

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.

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 ".

'\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.

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>.

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.

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>).

If you want to use - <quote>aliases</quote> in an actions file, you have to place the (optional) - <link linkend="aliases">alias section</link> at the top of that file. - Then comes the default set of rules which will apply universally to all - sites and pages (be <emphasis>very careful</emphasis> with using such a - universal set in <filename>user.action</filename> or any other actions file after - <filename>default.action</filename>, because it will override the result - from consulting any previous file). And then below that, - exceptions to the defined universal policies. You can regard - <filename>user.action</filename> as an appendix to <filename>default.action</filename>, - with the advantage that it is a separate file, which makes preserving your - personal settings across <application>Privoxy</application> upgrades easier. -</para> - -<para> - Actions can be used to block anything you want, including ads, banners, or - just some obnoxious URL whose content you would rather not see. Cookies can be accepted - or rejected, or accepted only during the current browser session (i.e. not - written to disk), content can be modified, some JavaScripts tamed, user-tracking - fooled, and much more.

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.

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.

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.

We can mark any - URL as an image with the <literal><link - linkend="handle-as-image">handle-as-image</link></literal> action, - and marking all URLs that end in a known image file extension is a - good start: -</para> - -<para> - <screen> -########################################################################## -# Images: -########################################################################## - -# Define which file types will be treated as images, in case they get -# blocked further down this file: -# -{ +<link linkend="HANDLE-AS-IMAGE">handle-as-image</link> } -/.*\.(gif|jpe?g|png|bmp|ico)$</screen> -</para> - -<para> - And then there are known banner sources. They often use scripts to - generate the banners, so it won't be visible from the URL that the - request is for an image. Hence we block them <emphasis>and</emphasis> - mark them as images in one go, with the help of our - <literal>+block-as-image</literal> alias defined above. (We could of - course just as well use <literal>+<link linkend="block">block</link> - +<link linkend="handle-as-image">handle-as-image</link></literal> here.) - Remember that the type of the replacement image is chosen by the - <literal><link linkend="set-image-blocker">set-image-blocker</link></literal> - action. Since all URLs have matched the default section with its - <literal>+<link linkend="set-image-blocker">set-image-blocker</link>{pattern}</literal> - action before, it still applies and needn't be repeated: -</para> - -<para> - <screen> -# Known ad generators: -# -{ +block-as-image } -ar.atwola.com -.ad.doubleclick.net -.ad.*.doubleclick.net -.a.yimg.com/(?:(?!/i/).)*$ -.a[0-9].yimg.com/(?:(?!/i/).)*$ -bs*.gsanet.com -.qkimg.net</screen> -</para> - -<para> - One of the most important jobs of <application>Privoxy</application> - is to block banners. Many of these can be <quote>blocked</quote> - by the <literal><link linkend="filter">filter</link>{banners-by-size}</literal> - action, which we enabled above, and which deletes the references to banner - images from the pages while they are loaded, so the browser doesn't request - them anymore, and hence they don't need to be blocked here. But this naturally - doesn't catch all banners, and some people choose not to use filters, so we - need a comprehensive list of patterns for banner URLs here, and apply the - <literal><link linkend="block">block</link></literal> action to them. -</para> -<para> - First comes many generic patterns, which do most of the work, by - matching typical domain and path name components of banners. Then comes - a list of individual patterns for specific sites, which is omitted here - to keep the example short: -</para> - -<para> - <screen> -########################################################################## -# Block these fine banners: -########################################################################## -{ <link linkend="BLOCK">+block{Banner ads.}</link> } - -# Generic patterns: -# -ad*. -.*ads. -banner?. -count*. -/.*count(er)?\.(pl|cgi|exe|dll|asp|php[34]?) -/(?:.*/)?(publicite|werbung|rekla(ma|me|am)|annonse|maino(kset|nta|s)?)/ - -# Site-specific patterns (abbreviated): -# -.hitbox.com</screen> -</para> - -<para> - It's quite remarkable how many advertisers actually call their banner - servers ads.<replaceable>company</replaceable>.com, or call the directory - in which the banners are stored simply <quote>banners</quote>. So the above - generic patterns are surprisingly effective. -</para> -<para> - But being very generic, they necessarily also catch URLs that we don't want - to block. The pattern <literal>.*ads.</literal> e.g. catches - <quote>nasty-<emphasis>ads</emphasis>.nasty-corp.com</quote> as intended, - but also <quote>downlo<emphasis>ads</emphasis>.sourcefroge.net</quote> or - <quote><emphasis>ads</emphasis>l.some-provider.net.</quote> So here come some - well-known exceptions to the <literal>+<link linkend="BLOCK">block</link></literal> - section above. -</para> -<para> - Note that these are exceptions to exceptions from the default! Consider the URL - <quote>downloads.sourcefroge.net</quote>: Initially, all actions are deactivated, - so it wouldn't get blocked. Then comes the defaults section, which matches the - URL, but just deactivates the <literal><link linkend="BLOCK">block</link></literal> - action once again. Then it matches <literal>.*ads.</literal>, an exception to the - general non-blocking policy, and suddenly - <literal><link linkend="BLOCK">+block</link></literal> applies. And now, it'll match - <literal>.*loads.</literal>, where <literal><link linkend="BLOCK">-block</link></literal> - applies, so (unless it matches <emphasis>again</emphasis> further down) it ends up - with no <literal><link linkend="BLOCK">block</link></literal> action applying. -</para> - -<para> - <screen> -########################################################################## -# Save some innocent victims of the above generic block patterns: -########################################################################## - -# By domain: -# -{ -<link linkend="BLOCK">block</link> } -adv[io]*. # (for advogato.org and advice.*) -adsl. # (has nothing to do with ads) -adobe. # (has nothing to do with ads either) -ad[ud]*. # (adult.* and add.*) -.edu # (universities don't host banners (yet!)) -.*loads. # (downloads, uploads etc) - -# By path: -# -/.*loads/ - -# Site-specific: -# -www.globalintersec.com/adv # (adv = advanced) -www.ugu.com/sui/ugu/adv</screen> -</para> - -<para> - Filtering source code can have nasty side effects, - so make an exception for our friends at sourceforge.net, - and all paths with <quote>cvs</quote> in them.

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.

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&gt 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.

Basta. - This job replaces the <quote>onunload</quote> attribute in - <quote><body&gt</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&gt 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.

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.

The browser knows to send - the request to <application>Privoxy</application>, which will in turn, - relay the request to the remote web server after passing the following - tests: - </para> - </listitem> - <listitem> - <para> - <application>Privoxy</application> traps any request for its own internal CGI - pages (e.g <ulink url="http://p.p/">http://p.p/</ulink>) and sends the CGI page back to the browser. - </para> - </listitem> - <listitem> - <para> - Next, <application>Privoxy</application> checks to see if the URL - matches any <link - linkend="BLOCK"><quote>+block</quote></link> patterns. If - so, the URL is then blocked, and the remote web server will not be contacted. - <link linkend="HANDLE-AS-IMAGE"><quote>+handle-as-image</quote></link> - and - <link linkend="HANDLE-AS-EMPTY-DOCUMENT"><quote>+handle-as-empty-document</quote></link> - are then checked, and if there is no match, an - HTML <quote>BLOCKED</quote> page is sent back to the browser. Otherwise, if - it does match, an image is returned for the former, and an empty text - document for the latter. The type of image would depend on the setting of - <link linkend="SET-IMAGE-BLOCKER"><quote>+set-image-blocker</quote></link> - (blank, checkerboard pattern, or an HTTP redirect to an image elsewhere). - </para> - </listitem> - <listitem> - <para> - Untrusted URLs are blocked. If URLs are being added to the - <filename>trust</filename> file, then that is done. - </para> - </listitem> - <listitem> - <para> - If the URL pattern matches the <link - linkend="FAST-REDIRECTS"><quote>+fast-redirects</quote></link> action, - it is then processed. Unwanted parts of the requested URL are stripped. - </para> - </listitem> - <listitem> - <para> - Now the rest of the client browser's request headers are processed. If any - of these match any of the relevant actions (e.g. <link - linkend="HIDE-USER-AGENT"><quote>+hide-user-agent</quote></link>, - etc.), headers are suppressed or forged as determined by these actions and - their parameters. - </para> - </listitem> - <listitem> - <para> - Now the web server starts sending its response back (i.e. typically a web - page). - </para> - </listitem> - <listitem> - <para> - First, the server headers are read and processed to determine, among other - things, the MIME type (document type) and encoding. The headers are then - filtered as determined by the - <link linkend="CRUNCH-INCOMING-COOKIES"><quote>+crunch-incoming-cookies</quote></link>, - <link linkend="SESSION-COOKIES-ONLY"><quote>+session-cookies-only</quote></link>, - and <link linkend="DOWNGRADE-HTTP-VERSION"><quote>+downgrade-http-version</quote></link> - actions. - </para> - </listitem> - <listitem> - <para> - If any <link linkend="FILTER"><quote>+filter</quote></link> action - or <link - linkend="DEANIMATE-GIFS"><quote>+deanimate-gifs</quote></link> - action applies (and the document type fits the action), the rest of the page is - read into memory (up to a configurable limit). Then the filter rules (from - <filename>default.filter</filename> and any other filter files) are - processed against the buffered content. Filters are applied in the order - they are specified in one of the filter files. Animated GIFs, if present, - are reduced to either the first or last frame, depending on the action - setting.The entire page, which is now filtered, is then sent by - <application>Privoxy</application> back to your browser. - </para> - <para> - If neither a <link linkend="FILTER"><quote>+filter</quote></link> action - or <link - linkend="DEANIMATE-GIFS"><quote>+deanimate-gifs</quote></link> - matches, then <application>Privoxy</application> passes the raw data through - to the client browser as it becomes available. - </para> - </listitem> - <listitem> - <para> - As the browser receives the now (possibly filtered) page content, it - reads and then requests any URLs that may be embedded within the page - source, e.g. ad images, stylesheets, JavaScript, other HTML documents (e.g. - frames), sounds, etc. For each of these objects, the browser issues a - separate request (this is easily viewable in <application>Privoxy's</application> - logs). And each such request is in turn processed just as above. Note that a - complex web page will have many, many such embedded URLs. If these - secondary requests are to a different server, then quite possibly a very - differing set of actions is triggered. - </para> - </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. -</para> - -</sect2> - - - -<sect2 id="actionsanat"> -<title>Troubleshooting: Anatomy of an Action</title> - -<para> - The way <application>Privoxy</application> applies - <link linkend="ACTIONS">actions</link> and <link linkend="FILTER">filters</link> - to any given URL can be complex, and not always so - easy to understand what is happening. And sometimes we need to be able to - <emphasis>see</emphasis> just what <application>Privoxy</application> is - doing. Especially, if something <application>Privoxy</application> is doing - is causing us a problem inadvertently. It can be a little daunting to look at - the actions and filters files themselves, since they tend to be filled with - <link linkend="regex">regular expressions</link> whose consequences are not - always so obvious. -</para> - -<para> - One quick test to see if <application>Privoxy</application> is causing a problem - or not, is to disable it temporarily. This should be the first troubleshooting - step. See <link linkend="bookmarklets">the Bookmarklets</link> section on a quick - and easy way to do this (be sure to flush caches afterward!). Looking at the - logs is a good idea too. (Note that both the toggle feature and logging are - enabled via <filename>config</filename> file settings, and may need to be - turned <quote>on</quote>.) -</para> -<para> - Another easy troubleshooting step to try is if you have done any - customization of your installation, revert back to the installed - defaults and see if that helps. There are times the developers get complaints - about one thing or another, and the problem is more related to a customized - configuration issue. -</para> - -<para> - <application>Privoxy</application> also provides the - <ulink url="http://config.privoxy.org/show-url-info">http://config.privoxy.org/show-url-info</ulink> - page that can show us very specifically how <application>actions</application> - are being applied to any given URL. This is a big help for troubleshooting. -</para> - -<para> - First, enter one URL (or partial URL) at the prompt, and then - <application>Privoxy</application> will tell us - how the current configuration will handle it. This will not - help with filtering effects (i.e. the <link - linkend="FILTER"><quote>+filter</quote></link> action) from - one of the filter files since this is handled very - differently and not so easy to trap! It also will not tell you about any other - URLs that may be embedded within the URL you are testing. For instance, images - such as ads are expressed as URLs within the raw page source of HTML pages. So - you will only get info for the actual URL that is pasted into the prompt area - -- not any sub-URLs. If you want to know about embedded URLs like ads, you - will have to dig those out of the HTML source. Use your browser's <quote>View - Page Source</quote> option for this. Or right click on the ad, and grab the - URL. -</para> - -<para> - Let's try an example, <ulink url="http://google.com">google.com</ulink>, - and look at it one section at a time in a sample configuration (your real - configuration may vary): -</para> - -<para> - <screen> - Matches for http://www.google.com: - - In file: default.action <guibutton>[ View ]</guibutton> <guibutton>[ Edit ]</guibutton> - - {+change-x-forwarded-for{block} - +deanimate-gifs {last} - +fast-redirects {check-decoded-url} - +filter {refresh-tags} - +filter {img-reorder} - +filter {banners-by-size} - +filter {webbugs} - +filter {jumping-windows} - +filter {ie-exploits} - +hide-from-header {block} - +hide-referrer {forge} - +session-cookies-only - +set-image-blocker {pattern} -/ - - { -session-cookies-only } - .google.com - - { -fast-redirects } - .google.com - -In file: user.action <guibutton>[ View ]</guibutton> <guibutton>[ Edit ]</guibutton> -(no matches in this file) -</screen> -</para> - -<para> - This is telling us how we have defined our - <link linkend="ACTIONS"><quote>actions</quote></link>, and - which ones match for our test case, <quote>google.com</quote>. - Displayed is all the actions that are available to us. Remember, - the <literal>+</literal> sign denotes <quote>on</quote>. <literal>-</literal> - denotes <quote>off</quote>. So some are <quote>on</quote> here, but many - are <quote>off</quote>. Each example we try may provide a slightly different - end result, depending on our configuration directives. -</para> -<para> - The first listing - is for our <filename>default.action</filename> file. The large, multi-line - listing, is how the actions are set to match for all URLs, i.e. our default - settings. If you look at your <quote>actions</quote> file, this would be the - section just below the <quote>aliases</quote> section near the top. This - will apply to all URLs as signified by the single forward slash at the end - of the listing -- <quote> / </quote>. -</para> - -<para> - But we have defined additional actions that would be exceptions to these general - rules, and then we list specific URLs (or patterns) that these exceptions - would apply to. Last match wins. Just below this then are two explicit - matches for <quote>.google.com</quote>. The first is negating our previous - cookie setting, which was for <link - linkend="SESSION-COOKIES-ONLY"><quote>+session-cookies-only</quote></link> - (i.e. not persistent). So we will allow persistent cookies for google, at - least that is how it is in this example. The second turns - <emphasis>off</emphasis> any <link - linkend="FAST-REDIRECTS"><quote>+fast-redirects</quote></link> - action, allowing this to take place unmolested. Note that there is a leading - dot here -- <quote>.google.com</quote>. This will match any hosts and - sub-domains, in the google.com domain also, such as - <quote>www.google.com</quote> or <quote>mail.google.com</quote>. But it would not - match <quote>www.google.de</quote>! So, apparently, we have these two actions - defined as exceptions to the general rules at the top somewhere in the lower - part of our <filename>default.action</filename> file, and - <quote>google.com</quote> is referenced somewhere in these latter sections. -</para> - -<para> - Then, for our <filename>user.action</filename> file, we again have no hits. - So there is nothing google-specific that we might have added to our own, local - configuration. If there was, those actions would over-rule any actions from - previously processed files, such as <filename>default.action</filename>. - <filename>user.action</filename> typically has the last word. This is the - best place to put hard and fast exceptions, -</para> - -<para> - And finally we pull it all together in the bottom section and summarize how - <application>Privoxy</application> is applying all its <quote>actions</quote> - to <quote>google.com</quote>: - -</para> - -<para> - <screen> - - Final results: - - -add-header - -block - +change-x-forwarded-for{block} - -client-header-filter{hide-tor-exit-notation} - -content-type-overwrite - -crunch-client-header - -crunch-if-none-match - -crunch-incoming-cookies - -crunch-outgoing-cookies - -crunch-server-header - +deanimate-gifs {last} - -downgrade-http-version - -fast-redirects - -filter {js-events} - -filter {content-cookies} - -filter {all-popups} - -filter {banners-by-link} - -filter {tiny-textforms} - -filter {frameset-borders} - -filter {demoronizer} - -filter {shockwave-flash} - -filter {quicktime-kioskmode} - -filter {fun} - -filter {crude-parental} - -filter {site-specifics} - -filter {js-annoyances} - -filter {html-annoyances} - +filter {refresh-tags} - -filter {unsolicited-popups} - +filter {img-reorder} - +filter {banners-by-size} - +filter {webbugs} - +filter {jumping-windows} - +filter {ie-exploits} - -filter {google} - -filter {yahoo} - -filter {msn} - -filter {blogspot} - -filter {no-ping} - -force-text-mode - -handle-as-empty-document - -handle-as-image - -hide-accept-language - -hide-content-disposition - +hide-from-header {block} - -hide-if-modified-since - +hide-referrer {forge} - -hide-user-agent - -limit-connect - -overwrite-last-modified - -prevent-compression - -redirect - -server-header-filter{xml-to-html} - -server-header-filter{html-to-xml} - -session-cookies-only - +set-image-blocker {pattern} </screen> -</para> - -<para> - Notice the only difference here to the previous listing, is to - <quote>fast-redirects</quote> and <quote>session-cookies-only</quote>, - which are activated specifically for this site in our configuration, - and thus show in the <quote>Final Results</quote>. -</para> - -<para> - Now another example, <quote>ad.doubleclick.net</quote>: -</para> - -<para> - <screen> - - { +block{Domains starts with "ad"} } - ad*. - - { +block{Domain contains "ad"} } - .ad. - - { +block{Doubleclick banner server} +handle-as-image } - .[a-vx-z]*.doubleclick.net -</screen> -</para> - -<para> - We'll just show the interesting part here - the explicit matches. It is - matched three different times. Two <quote>+block{}</quote> sections, - and a <quote>+block{} +handle-as-image</quote>, - which is the expanded form of one of our aliases that had been defined as: - <quote>+block-as-image</quote>. (<link - linkend="ALIASES"><quote>Aliases</quote></link> are defined in - the first section of the actions file and typically used to combine more - than one action.) -</para> - -<para> - Any one of these would have done the trick and blocked this as an unwanted - image. This is unnecessarily redundant since the last case effectively - would also cover the first. No point in taking chances with these guys - though ;-) Note that if you want an ad or obnoxious - URL to be invisible, it should be defined as <quote>ad.doubleclick.net</quote> - is done here -- as both a <link - linkend="BLOCK"><quote>+block{}</quote></link> - <emphasis>and</emphasis> an - <link linkend="HANDLE-AS-IMAGE"><quote>+handle-as-image</quote></link>. - The custom alias <quote><literal>+block-as-image</literal></quote> just - simplifies the process and make it more readable. -</para> - -<para> - One last example.

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.

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.

Releasing a New Version</A -></H1 -><P -> When we release versions of <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN ->, - 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. - </P -><P -> So when releasing a new version, please adhere exactly to the - procedure outlined in this chapter. - </P -><P -> The following programs are required to follow this process: - <TT -CLASS="FILENAME" ->ncftpput</TT -> (ncftp), <TT -CLASS="FILENAME" ->scp, ssh</TT -> (ssh), - <TT -CLASS="FILENAME" ->gmake</TT -> (GNU's version of make), autoconf, cvs. - </P -><DIV -CLASS="SECT2" -><H2 -CLASS="SECT2" -><A -NAME="VERSIONNUMBERS" ->6.1. Version numbers</A -></H2 -><P -> First you need to determine which version number the release will have. - <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> version numbers consist of three numbers, - separated by dots, like in X.Y.Z (e.g. 3.0.0), where: - <P -></P -><UL -><LI -><P -> X, the version major, is rarely ever changed. It is increased by one if - turning a development branch into stable substantially changes the functionality, - user interface or configuration syntax. Majors 1 and 2 were - <SPAN -CLASS="APPLICATION" ->Junkbuster</SPAN ->, and 3 will be the first stable - <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> release. - </P -></LI -><LI -><P -> Y, the version minor, represents the branch within the major version. - At any point in time, there are two branches being maintained: - The stable branch, with an even minor, say, 2N, in which no functionality is - being added and only bug-fixes are made, and 2N+1, the development branch, in - which the further development of <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> takes - place. - This enables us to turn the code upside down and inside out, while at the same time - providing and maintaining a stable version. - The minor is reset to zero (and one) when the major is incremented. When a development - branch has matured to the point where it can be turned into stable, the old stable branch - 2N is given up (i.e. no longer maintained), the former development branch 2N+1 becomes the - new stable branch 2N+2, and a new development branch 2N+3 is opened. - </P -></LI -><LI -><P -> Z, the point or sub version, represents a release of the software within a branch. - It is therefore incremented immediately before each code freeze. - In development branches, only the even point versions correspond to actual releases, - while the odd ones denote the evolving state of the sources on CVS in between. - It follows that Z is odd on CVS in development branches most of the time. There, it gets - increased to an even number immediately before a code freeze, and is increased to an odd - number again immediately thereafter. - This ensures that builds from CVS snapshots are easily distinguished from released versions. - The point version is reset to zero when the minor changes. - </P -><P -> Stable branches work a little differently, since there should be - little to no development happening in such branches. Remember, - only bugfixes, which presumably should have had some testing - before being committed. Stable branches will then have their - version reported as <TT -CLASS="LITERAL" ->0.0.0</TT ->, during that period - between releases when changes are being added. This is to denote - that this code is <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->not for release</I -></SPAN ->. Then - as the release nears, the version is bumped according: e.g. - <TT -CLASS="LITERAL" ->3.0.1 -> 0.0.0 -> 3.0.2</TT ->. - </P -></LI -></UL -> - </P -><P -> In summary, the main CVS trunk is the development branch where new - features are being worked on for the next stable series. This should - almost always be where the most activity takes place. There is always at - least one stable branch from the trunk, e.g now it is - <TT -CLASS="LITERAL" ->3.0</TT ->, which is only used to release stable versions. - Once the initial *.0 release of the stable branch has been done, then as a - rule, only bugfixes that have had prior testing should be committed to - the stable branch. Once there are enough bugfixes to justify a new - release, the version of this branch is again incremented Example: 3.0.0 - -> 3.0.1 -> 3.0.2, etc are all stable releases from within the stable - branch. 3.1.x is currently the main trunk, and where work on 3.2.x is - taking place. If any questions, please post to the devel list - <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->before</I -></SPAN -> committing to a stable branch! - </P -><P -> Developers should remember too that if they commit a bugfix to the stable - branch, this will more than likely require a separate submission to the - 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, <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->and</I -></SPAN -> the stable release branch, - which is <TT -CLASS="LITERAL" ->v_3_0_branch</TT -> at the moment). - </P -></DIV -><DIV -CLASS="SECT2" -><H2 -CLASS="SECT2" -><A -NAME="BEFORERELEASE" ->6.2.

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. - </P -></DIV -><DIV -CLASS="SECT2" -><H3 -CLASS="SECT2" -><A -NAME="OTHERSTUFF" ->1.4. Does Privoxy do anything more than ad blocking?</A -></H3 -><P -> - Yes, ad blocking is but one possible use.

What is this new version of -<SPAN -CLASS="QUOTE" ->"Junkbuster"</SPAN ->?</A -></H3 -><P -> A long time ago, there was the - <A -HREF="http://www.junkbusters.com/ijb.html" -TARGET="_top" -><SPAN -CLASS="APPLICATION" ->Internet Junkbuster</SPAN -></A ->, - by Anonymous Coders and <A -HREF="http://www.junkbusters.com/" -TARGET="_top" ->Junkbusters - Corporation</A ->. This saved many users a lot of pain in the early days of - web advertising and user tracking.</P -><P -> But the web, its protocols and standards, and with it, the techniques for - forcing ads on users, give up autonomy over their browsing, and - for tracking them, keeps evolving. Unfortunately, the <SPAN -CLASS="APPLICATION" ->Internet - Junkbuster</SPAN -> did not. Version 2.0.2, published in 1998, was - (and is) the last official - <A -HREF="http://www.junkbusters.com/ijbdist.html#release" -TARGET="_top" ->release</A -> - available from <A -HREF="http://www.junkbusters.com" -TARGET="_top" ->Junkbusters Corporation</A ->. - Fortunately, it had been released under the GNU - <A -HREF="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" -TARGET="_top" ->GPL</A ->, - which allowed further development by others.</P -><P -> So Stefan Waldherr started maintaining an improved version of the - software, to which eventually a number of people contributed patches. - It could already replace banners with a transparent image, and had a first - version of pop-up killing, but it was still very closely based on the - original, with all its limitations, such as the lack of HTTP/1.1 support, - flexible per-site configuration, or content modification. The last release - from this effort was version 2.0.2-10, published in 2000.</P -><P -> Then, some - <A -HREF="http://www.privoxy.org/user-manual/copyright.html#AUTHORS" -TARGET="_top" ->developers</A -> - picked up the thread, and started turning the software inside out, upside down, - and then reassembled it, adding many - <A -HREF="http://www.privoxy.org/user-manual/introduction.html#FEATURES" -TARGET="_top" ->new - features</A -> along the way.</P -><P -> The result of this is <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN ->, whose first - stable version, 3.0, was released August, 2002. - </P -></DIV -><DIV -CLASS="SECT2" -><H3 -CLASS="SECT2" -><A -NAME="AEN78" ->1.6.

How does Privoxy differ -from the old Junkbuster?</A -></H3 -><P -> <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> picks up where - <SPAN -CLASS="APPLICATION" ->Junkbuster</SPAN -> left off. - The new <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> still blocks ads and banners, - still manages <A -HREF="http://en.wikipedia.org/wiki/Browser_cookie" -TARGET="_top" ->cookies</A ->, and still - helps protect your privacy.

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" -><H3 -CLASS="SECT2" -><A -NAME="AEN160" ->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. - (<A -HREF="trouble.html#BADSITE" ->See the Troubleshooting section below</A ->.)</P -></DIV -><DIV -CLASS="SECT2" -><H3 -CLASS="SECT2" -><A -NAME="AEN166" ->1.10. Will I have to configure Privoxy - before I can use it?</A -></H3 -><P -> 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 -><P -> You do have to set up your browser to use - <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 -CLASS="APPLICATION" ->Privoxy's</SPAN -> - configuration to more closely match your individual situation. And we - encourage you to do this. This is where the real power of - <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> lies!</P -></DIV -><DIV -CLASS="SECT2" -><H3 -CLASS="SECT2" -><A -NAME="LAN" ->1.11. Can Privoxy run as a server on a network?</A -></H3 -><P -> - Yes, <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> runs as a server already, and can easily be configured to - <SPAN -CLASS="QUOTE" ->"serve"</SPAN -> more than one client. See <A -HREF="configuration.html#LANCONFIG" -> How can I set up Privoxy to act as a proxy for my LAN</A -> below.</P -></DIV -><DIV -CLASS="SECT2" -><H3 -CLASS="SECT2" -><A -NAME="BROWSERS2" ->1.12. My browser does the same things as -Privoxy. Why should I use Privoxy at all?</A -></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. - </P -></DIV -><DIV -CLASS="SECT2" -><H3 -CLASS="SECT2" -><A -NAME="WHYTRUST" ->1.13. Why should I trust Privoxy?</A -></H3 -><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 ->. In fact, we encourage this level of scrutiny.

There are many, many ways that this can be handled, - so having hard and fast rules, is tricky.</P -><P -> The <SPAN -CLASS="QUOTE" ->"User-Agent"</SPAN -> is sometimes used in this way to identify - the browser, and adjust content accordingly.</P -><P -> Also, different browsers use different encodings of non-English - characters, certain web servers convert pages on-the-fly according to the - User Agent header. Giving a <SPAN -CLASS="QUOTE" ->"User Agent"</SPAN -> with the wrong - operating system or browser manufacturer causes some sites in these languages - to be garbled; Surfers to Eastern European sites should change it to - something closer.

I have large empty spaces / a checkerboard pattern now where -ads used to be. Why?</A -></H3 -><P -> It is technically possible to eliminate banners and ads in a way that frees - their allocated page space. This could easily be done by blocking with - <SPAN -CLASS="APPLICATION" ->Privoxy's</SPAN -> filters, - and eliminating the <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->entire</I -></SPAN -> image references from the - HTML page source. </P -><P -> But, this would consume considerably more CPU resources (IOW, slow things - down), would likely destroy the layout of some web pages which rely on the - banners utilizing a certain amount of page space, and might fail in other - cases, where the screen space is reserved (e.g. by HTML tables for instance). - Also, making ads and banners disappear without any trace complicates - troubleshooting, and would sooner or later be problematic.</P -><P -> The better alternative is to instead let them stay, and block the resulting - requests for the banners themselves as is now the case.

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

When you set your system up you will probably have set - up Internet Connection Sharing (ICS) with Dial up Networking (DUN) when - logged in with administrator privileges. You will probably have made this DUN - connection available to other accounts that you may have set-up on your - system. E.g. Mum or Dad sets up the system and makes accounts suitably - configured for the kids.</P -><P -> When setting up <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> in this environment you - will have to alter the proxy set-up of Internet Explorer (IE) for the - specific DUN connection on which you wish to use - <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN ->. When you do this the ICS DUN set-up - becomes user specific. In this instance you will see no difference if you - change the DUN connection under the account used to set-up the connection. - However when you do this from another user you will notice that the DUN - connection changes to make available to "Me only". You will also find that - you have to store the password under each different user!</P -><P -> The reason for this is that each user's set-up for IE is user specific. Each - set-up DUN connection and each LAN connection in IE store the settings for - each user individually. As such this enforces individual configurations - rather than common ones. Hence the first time you use a DUN connection after - re-booting your system it may not perform as you expect, and prompt you for - the password. Just set and save the password again and all should be OK.</P -><P ->[Thanks to Ray Griffith for this submission.]</P -></DIV -><DIV -CLASS="SECT2" -><H3 -CLASS="SECT2" -><A -NAME="FTP" ->5.6.

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

Finding the right mix of actions is not always easy and - certainly a matter of personal taste. And, things can always change, requiring - refinements in the configuration. In general, it can be said that the more - <SPAN -CLASS="QUOTE" ->"aggressive"</SPAN -> your default settings (in the top section of the - actions file) are, the more exceptions for <SPAN -CLASS="QUOTE" ->"trusted"</SPAN -> 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.</P -><P -> We have tried to provide you with reasonable rules to start from in the - distribution actions files.

The editor allows both fine-grained control over every single - feature on a per-URL basis, and easy choosing from wholesale sets of defaults - like <SPAN -CLASS="QUOTE" ->"Cautious"</SPAN ->, <SPAN -CLASS="QUOTE" ->"Medium"</SPAN -> or - <SPAN -CLASS="QUOTE" ->"Advanced"</SPAN ->. Warning: the <SPAN -CLASS="QUOTE" ->"Advanced"</SPAN -> setting is more - aggressive, and will be more likely to cause problems for some sites. - Experienced users only! - </P -><P -> If you prefer plain text editing to GUIs, you can of course also directly edit the - the actions files with your favorite text editor. Look at - <TT -CLASS="FILENAME" ->default.action</TT -> which is richly commented with many - good examples.</P -></DIV -><DIV -CLASS="SECT2" -><H2 -CLASS="SECT2" -><A -NAME="ACTIONS-APPLY" ->8.3. How Actions are Applied to Requests</A -></H2 -><P -> Actions files are divided into sections. There are special sections, - like the <SPAN -CLASS="QUOTE" ->"<A -HREF="actions-file.html#ALIASES" ->alias</A ->"</SPAN -> sections which will - be discussed later. For now let's concentrate on regular sections: They have a - heading line (often split up to multiple lines for readability) which consist - of a list of actions, separated by whitespace and enclosed in curly braces. - Below that, there is a list of URL and tag patterns, each on a separate line.</P -><P -> To determine which actions apply to a request, the URL of the request is - compared to all URL patterns in each <SPAN -CLASS="QUOTE" ->"action file"</SPAN ->. - Every time it matches, the list of applicable actions for the request is - incrementally updated, using the heading of the section in which the - pattern is located. The same is done again for tags and tag patterns later on.</P -><P -> If multiple applying sections set the same action differently, - the last match wins. If not, the effects are aggregated. - E.g. a URL might match a regular section with a heading line of <TT -CLASS="LITERAL" ->{ - +<A -HREF="actions-file.html#HANDLE-AS-IMAGE" ->handle-as-image</A -> }</TT ->, - then later another one with just <TT -CLASS="LITERAL" ->{ - +<A -HREF="actions-file.html#BLOCK" ->block</A -> }</TT ->, resulting - in <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->both</I -></SPAN -> actions to apply. And there may well be - cases where you will want to combine actions together. Such a section then - might look like:</P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><PRE -CLASS="SCREEN" -> { +<TT -CLASS="LITERAL" ->handle-as-image</TT -> +<TT -CLASS="LITERAL" ->block{Banner ads.}</TT -> } - # Block these as if they were images.

These <SPAN -CLASS="QUOTE" ->"patterns"</SPAN -> use wild - card type <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->pattern</I -></SPAN -> matching to achieve a high degree of - flexibility. This allows one expression to be expanded and potentially match - against many similar patterns.</P -><P -> Generally, an URL pattern has the form - <TT -CLASS="LITERAL" -><domain>/<path></TT ->, where both the - <TT -CLASS="LITERAL" -><domain></TT -> and <TT -CLASS="LITERAL" -><path></TT -> are - optional. (This is why the special <TT -CLASS="LITERAL" ->/</TT -> pattern matches all - URLs). Note that the protocol portion of the URL pattern (e.g. - <TT -CLASS="LITERAL" ->http://</TT ->) should <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->not</I -></SPAN -> be included in - the pattern. This is assumed already!</P -><P -> The pattern matching syntax is different for the domain and path parts of - the URL.

As a result - tags can be used to activate other tagger actions, as long as these other - taggers look for headers that haven't already be parsed.</P -><P -> For example you could tag client requests which use the - <TT -CLASS="LITERAL" ->POST</TT -> method, - then use this tag to activate another tagger that adds a tag if cookies - are sent, and then use a block action based on the cookie tag. This allows - the outcome of one action, to be input into a subsequent action. However if - you'd reverse the position of the described taggers, and activated the - 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.</P -><P -> 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.</P -></DIV -></DIV -><DIV -CLASS="SECT2" -><H2 -CLASS="SECT2" -><A -NAME="ACTIONS" ->8.5.

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" ->"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.

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

Troubleshooting: Anatomy of an Action</A -></H2 -><P -> The way <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> applies - <A -HREF="actions-file.html#ACTIONS" ->actions</A -> and <A -HREF="actions-file.html#FILTER" ->filters</A -> - to any given URL can be complex, and not always so - easy to understand what is happening. And sometimes we need to be able to - <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->see</I -></SPAN -> just what <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> is - doing. Especially, if something <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> is doing - is causing us a problem inadvertently. It can be a little daunting to look at - the actions and filters files themselves, since they tend to be filled with - <A -HREF="appendix.html#REGEX" ->regular expressions</A -> whose consequences are not - always so obvious. </P -><P -> One quick test to see if <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> is causing a problem - or not, is to disable it temporarily. This should be the first troubleshooting - step. See <A -HREF="appendix.html#BOOKMARKLETS" ->the Bookmarklets</A -> section on a quick - and easy way to do this (be sure to flush caches afterward!). Looking at the - logs is a good idea too. (Note that both the toggle feature and logging are - enabled via <TT -CLASS="FILENAME" ->config</TT -> file settings, and may need to be - turned <SPAN -CLASS="QUOTE" ->"on"</SPAN ->.)</P -><P -> Another easy troubleshooting step to try is if you have done any - customization of your installation, revert back to the installed - defaults and see if that helps. There are times the developers get complaints - about one thing or another, and the problem is more related to a customized - configuration issue.</P -><P -> <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> also provides the - <A -HREF="http://config.privoxy.org/show-url-info" -TARGET="_top" ->http://config.privoxy.org/show-url-info</A -> - page that can show us very specifically how <SPAN -CLASS="APPLICATION" ->actions</SPAN -> - are being applied to any given URL. This is a big help for troubleshooting.</P -><P -> First, enter one URL (or partial URL) at the prompt, and then - <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> will tell us - how the current configuration will handle it. This will not - help with filtering effects (i.e. the <A -HREF="actions-file.html#FILTER" -><SPAN -CLASS="QUOTE" ->"+filter"</SPAN -></A -> action) from - one of the filter files since this is handled very - differently and not so easy to trap! It also will not tell you about any other - URLs that may be embedded within the URL you are testing. For instance, images - such as ads are expressed as URLs within the raw page source of HTML pages. So - you will only get info for the actual URL that is pasted into the prompt area - -- not any sub-URLs. If you want to know about embedded URLs like ads, you - will have to dig those out of the HTML source. Use your browser's <SPAN -CLASS="QUOTE" ->"View - Page Source"</SPAN -> option for this. Or right click on the ad, and grab the - URL.</P -><P -> Let's try an example, <A -HREF="http://google.com" -TARGET="_top" ->google.com</A ->, - and look at it one section at a time in a sample configuration (your real - configuration may vary):</P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><PRE -CLASS="SCREEN" -> Matches for http://www.google.com: - - In file: default.action <SPAN -CLASS="GUIBUTTON" ->[ View ]</SPAN -> <SPAN -CLASS="GUIBUTTON" ->[ Edit ]</SPAN -> - - {+change-x-forwarded-for{block} - +deanimate-gifs {last} - +fast-redirects {check-decoded-url} - +filter {refresh-tags} - +filter {img-reorder} - +filter {banners-by-size} - +filter {webbugs} - +filter {jumping-windows} - +filter {ie-exploits} - +hide-from-header {block} - +hide-referrer {forge} - +session-cookies-only - +set-image-blocker {pattern} -/ - - { -session-cookies-only } - .google.com - - { -fast-redirects } - .google.com - -In file: user.action <SPAN -CLASS="GUIBUTTON" ->[ View ]</SPAN -> <SPAN -CLASS="GUIBUTTON" ->[ Edit ]</SPAN -> -(no matches in this file) </PRE -></TD -></TR -></TABLE -></P -><P -> This is telling us how we have defined our - <A -HREF="actions-file.html#ACTIONS" -><SPAN -CLASS="QUOTE" ->"actions"</SPAN -></A ->, and - which ones match for our test case, <SPAN -CLASS="QUOTE" ->"google.com"</SPAN ->. - Displayed is all the actions that are available to us. Remember, - the <TT -CLASS="LITERAL" ->+</TT -> sign denotes <SPAN -CLASS="QUOTE" ->"on"</SPAN ->. <TT -CLASS="LITERAL" ->-</TT -> - denotes <SPAN -CLASS="QUOTE" ->"off"</SPAN ->. So some are <SPAN -CLASS="QUOTE" ->"on"</SPAN -> here, but many - are <SPAN -CLASS="QUOTE" ->"off"</SPAN ->. Each example we try may provide a slightly different - end result, depending on our configuration directives.</P -><P -> The first listing - is for our <TT -CLASS="FILENAME" ->default.action</TT -> file. The large, multi-line - listing, is how the actions are set to match for all URLs, i.e. our default - settings. If you look at your <SPAN -CLASS="QUOTE" ->"actions"</SPAN -> file, this would be the - section just below the <SPAN -CLASS="QUOTE" ->"aliases"</SPAN -> section near the top. This - will apply to all URLs as signified by the single forward slash at the end - of the listing -- <SPAN -CLASS="QUOTE" ->" / "</SPAN ->.</P -><P -> But we have defined additional actions that would be exceptions to these general - rules, and then we list specific URLs (or patterns) that these exceptions - would apply to. Last match wins. Just below this then are two explicit - matches for <SPAN -CLASS="QUOTE" ->".google.com"</SPAN ->. The first is negating our previous - cookie setting, which was for <A -HREF="actions-file.html#SESSION-COOKIES-ONLY" -><SPAN -CLASS="QUOTE" ->"+session-cookies-only"</SPAN -></A -> - (i.e. not persistent). So we will allow persistent cookies for google, at - least that is how it is in this example. The second turns - <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->off</I -></SPAN -> any <A -HREF="actions-file.html#FAST-REDIRECTS" -><SPAN -CLASS="QUOTE" ->"+fast-redirects"</SPAN -></A -> - action, allowing this to take place unmolested. Note that there is a leading - dot here -- <SPAN -CLASS="QUOTE" ->".google.com"</SPAN ->. This will match any hosts and - sub-domains, in the google.com domain also, such as - <SPAN -CLASS="QUOTE" ->"www.google.com"</SPAN -> or <SPAN -CLASS="QUOTE" ->"mail.google.com"</SPAN ->. But it would not - match <SPAN -CLASS="QUOTE" ->"www.google.de"</SPAN ->! So, apparently, we have these two actions - defined as exceptions to the general rules at the top somewhere in the lower - part of our <TT -CLASS="FILENAME" ->default.action</TT -> file, and - <SPAN -CLASS="QUOTE" ->"google.com"</SPAN -> is referenced somewhere in these latter sections.</P -><P -> Then, for our <TT -CLASS="FILENAME" ->user.action</TT -> file, we again have no hits. - So there is nothing google-specific that we might have added to our own, local - configuration. If there was, those actions would over-rule any actions from - previously processed files, such as <TT -CLASS="FILENAME" ->default.action</TT ->. - <TT -CLASS="FILENAME" ->user.action</TT -> typically has the last word. This is the - best place to put hard and fast exceptions,</P -><P -> And finally we pull it all together in the bottom section and summarize how - <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> is applying all its <SPAN -CLASS="QUOTE" ->"actions"</SPAN -> - to <SPAN -CLASS="QUOTE" ->"google.com"</SPAN ->:</P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><PRE -CLASS="SCREEN" -> Final results: - - -add-header - -block - +change-x-forwarded-for{block} - -client-header-filter{hide-tor-exit-notation} - -content-type-overwrite - -crunch-client-header - -crunch-if-none-match - -crunch-incoming-cookies - -crunch-outgoing-cookies - -crunch-server-header - +deanimate-gifs {last} - -downgrade-http-version - -fast-redirects - -filter {js-events} - -filter {content-cookies} - -filter {all-popups} - -filter {banners-by-link} - -filter {tiny-textforms} - -filter {frameset-borders} - -filter {demoronizer} - -filter {shockwave-flash} - -filter {quicktime-kioskmode} - -filter {fun} - -filter {crude-parental} - -filter {site-specifics} - -filter {js-annoyances} - -filter {html-annoyances} - +filter {refresh-tags} - -filter {unsolicited-popups} - +filter {img-reorder} - +filter {banners-by-size} - +filter {webbugs} - +filter {jumping-windows} - +filter {ie-exploits} - -filter {google} - -filter {yahoo} - -filter {msn} - -filter {blogspot} - -filter {no-ping} - -force-text-mode - -handle-as-empty-document - -handle-as-image - -hide-accept-language - -hide-content-disposition - +hide-from-header {block} - -hide-if-modified-since - +hide-referrer {forge} - -hide-user-agent - -limit-connect - -overwrite-last-modified - -prevent-compression - -redirect - -server-header-filter{xml-to-html} - -server-header-filter{html-to-xml} - -session-cookies-only - +set-image-blocker {pattern} </PRE -></TD -></TR -></TABLE -></P -><P -> Notice the only difference here to the previous listing, is to - <SPAN -CLASS="QUOTE" ->"fast-redirects"</SPAN -> and <SPAN -CLASS="QUOTE" ->"session-cookies-only"</SPAN ->, - which are activated specifically for this site in our configuration, - and thus show in the <SPAN -CLASS="QUOTE" ->"Final Results"</SPAN ->.</P -><P -> Now another example, <SPAN -CLASS="QUOTE" ->"ad.doubleclick.net"</SPAN ->:</P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><PRE -CLASS="SCREEN" -> { +block{Domains starts with "ad"} } - ad*. - - { +block{Domain contains "ad"} } - .ad. - - { +block{Doubleclick banner server} +handle-as-image } - .[a-vx-z]*.doubleclick.net</PRE -></TD -></TR -></TABLE -></P -><P -> We'll just show the interesting part here - the explicit matches.

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:</P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><PRE -CLASS="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</PRE -></TD -></TR -></TABLE -></P -><P -> Following the header line and a comment, you see the job. Note that it uses - <TT -CLASS="LITERAL" ->|</TT -> as the delimiter instead of <TT -CLASS="LITERAL" ->/</TT ->, because - the pattern contains a forward slash, which would otherwise have to be escaped - by a backslash (<TT -CLASS="LITERAL" ->\</TT ->).</P -><P -> Now, let's examine the pattern: it starts with the text <TT -CLASS="LITERAL" -><script.*</TT -> - enclosed in parentheses. Since the dot matches any character, and <TT -CLASS="LITERAL" ->*</TT -> - means: <SPAN -CLASS="QUOTE" ->"Match an arbitrary number of the element left of myself"</SPAN ->, this - matches <SPAN -CLASS="QUOTE" ->"<script"</SPAN ->, followed by <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->any</I -></SPAN -> text, i.e. - it matches the whole page, from the start of the first <script> tag.</P -><P -> That's more than we want, but the pattern continues: <TT -CLASS="LITERAL" ->document\.referrer</TT -> - matches only the exact string <SPAN -CLASS="QUOTE" ->"document.referrer"</SPAN ->. The dot needed to - be <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->escaped</I -></SPAN ->, i.e. preceded by a backslash, to take away its - special meaning as a joker, and make it just a regular dot. So far, the meaning is: - Match from the start of the first <script> tag in a the page, up to, and including, - the text <SPAN -CLASS="QUOTE" ->"document.referrer"</SPAN ->, if <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->both</I -></SPAN -> are present - in the page (and appear in that order).</P -><P -> But there's still more pattern to go. The next element, again enclosed in parentheses, - is <TT -CLASS="LITERAL" ->.*</script></TT ->. You already know what <TT -CLASS="LITERAL" ->.*</TT -> - means, so the whole pattern translates to: Match from the start of the first <script> - tag in a page to the end of the last <script> tag, provided that the text - <SPAN -CLASS="QUOTE" ->"document.referrer"</SPAN -> appears somewhere in between.</P -><P -> This is still not the whole story, since we have ignored the options and the parentheses: - The portions of the page matched by sub-patterns that are enclosed in parentheses, will be - remembered and be available through the variables <TT -CLASS="LITERAL" ->$1, $2, ...</TT -> in - the substitute. The <TT -CLASS="LITERAL" ->U</TT -> option switches to ungreedy matching, which means - that the first <TT -CLASS="LITERAL" ->.*</TT -> in the pattern will only <SPAN -CLASS="QUOTE" ->"eat up"</SPAN -> all - text in between <SPAN -CLASS="QUOTE" ->"<script"</SPAN -> and the <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->first</I -></SPAN -> occurrence - of <SPAN -CLASS="QUOTE" ->"document.referrer"</SPAN ->, and that the second <TT -CLASS="LITERAL" ->.*</TT -> will - only span the text up to the <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->first</I -></SPAN -> <SPAN -CLASS="QUOTE" ->"</script>"</SPAN -> - tag. Furthermore, the <TT -CLASS="LITERAL" ->s</TT -> option says that the match may span - multiple lines in the page, and the <TT -CLASS="LITERAL" ->g</TT -> option again means that the - substitution is global.</P -><P -> So, to summarize, the pattern means: Match all scripts that contain the text - <SPAN -CLASS="QUOTE" ->"document.referrer"</SPAN ->. Remember the parts of the script from - (and including) the start tag up to (and excluding) the string - <SPAN -CLASS="QUOTE" ->"document.referrer"</SPAN -> as <TT -CLASS="LITERAL" ->$1</TT ->, and the part following - that string, up to and including the closing tag, as <TT -CLASS="LITERAL" ->$2</TT ->.</P -><P -> Now the pattern is deciphered, but wasn't this about substituting things? So - lets look at the substitute: <TT -CLASS="LITERAL" ->$1"Not Your Business!"$2</TT -> is - easy to read: The text remembered as <TT -CLASS="LITERAL" ->$1</TT ->, followed by - <TT -CLASS="LITERAL" ->"Not Your Business!"</TT -> (<SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->including</I -></SPAN -> - the quotation marks!), followed by the text remembered as <TT -CLASS="LITERAL" ->$2</TT ->. - This produces an exact copy of the original string, with the middle part - (the <SPAN -CLASS="QUOTE" ->"document.referrer"</SPAN ->) replaced by <TT -CLASS="LITERAL" ->"Not Your - Business!"</TT ->.</P -><P -> The whole job now reads: Replace <SPAN -CLASS="QUOTE" ->"document.referrer"</SPAN -> by - <TT -CLASS="LITERAL" ->"Not Your Business!"</TT -> wherever it appears inside a - <script> tag. Note that this job won't break JavaScript syntax, - since both the original and the replacement are syntactically valid - string objects. The script just won't have access to the referrer - information anymore.</P -><P -> We'll show you two other jobs from the JavaScript taming department, but - this time only point out the constructs of special interest:</P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><PRE -CLASS="SCREEN" -># The status bar is for displaying link targets, not pointless blahblah -# -s/window\.status\s*=\s*(['"]).*?\1/dUmMy=1/ig</PRE -></TD -></TR -></TABLE -></P -><P -> <TT -CLASS="LITERAL" ->\s</TT -> stands for whitespace characters (space, tab, newline, - carriage return, form feed), so that <TT -CLASS="LITERAL" ->\s*</TT -> means: <SPAN -CLASS="QUOTE" ->"zero - or more whitespace"</SPAN ->. The <TT -CLASS="LITERAL" ->?</TT -> in <TT -CLASS="LITERAL" ->.*?</TT -> - makes this matching of arbitrary text ungreedy. (Note that the <TT -CLASS="LITERAL" ->U</TT -> - option is not set). The <TT -CLASS="LITERAL" ->['"]</TT -> construct means: <SPAN -CLASS="QUOTE" ->"a single - <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->or</I -></SPAN -> a double quote"</SPAN ->. Finally, <TT -CLASS="LITERAL" ->\1</TT -> is - a back-reference to the first parenthesis just like <TT -CLASS="LITERAL" ->$1</TT -> above, - with the difference that in the <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->pattern</I -></SPAN ->, a backslash indicates - a back-reference, whereas in the <SPAN -CLASS="emphasis" -><I -CLASS="EMPHASIS" ->substitute</I -></SPAN ->, it's the dollar.</P -><P -> So what does this job do? It replaces assignments of single- or double-quoted - strings to the <SPAN -CLASS="QUOTE" ->"window.status"</SPAN -> object with a dummy assignment - (using a variable name that is hopefully odd enough not to conflict with - real variables in scripts). Thus, it catches many cases where e.g. pointless - descriptions are displayed in the status bar instead of the link target when - you move your mouse over links.</P -><P -> <TABLE -BORDER="0" -BGCOLOR="#E0E0E0" -WIDTH="100%" -><TR -><TD -><PRE -CLASS="SCREEN" -># Kill OnUnload popups.

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

Filters - are very different from <TT -CLASS="LITERAL" -><A -HREF="actions-file.html#BLOCK" ->blocks</A -></TT ->. - A <SPAN -CLASS="QUOTE" ->"block"</SPAN -> 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 <SPAN -CLASS="QUOTE" ->"no-no"</SPAN -> for - <SPAN -CLASS="QUOTE" ->"nasty-word"</SPAN ->. That is a very simple example. This process can be - used for ad blocking, but it is more in the realm of advanced usage and has - some pitfalls to be wary off.</P -><P -> The quickest way to adjust any of these settings is with your browser through - the special <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> editor at <A -HREF="http://config.privoxy.org/show-status" -TARGET="_top" ->http://config.privoxy.org/show-status</A -> - (shortcut: <A -HREF="http://p.p/" -TARGET="_top" ->http://p.p/show-status</A ->). This - is an internal page, and does not require Internet access.</P -><P -> Note that as of <SPAN -CLASS="APPLICATION" ->Privoxy</SPAN -> 3.0.7 beta the - action editor is disabled by default.

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 - * - * - *********************************************************************/ - - -#include "config.h" - -#include <stdio.h> -#include <sys/types.h> -#include <stdlib.h> -#include <string.h> -#include <signal.h> -#include <fcntl.h> -#include <errno.h> -#include <assert.h> - -#ifdef _WIN32 -# ifndef FEATURE_PTHREAD -# ifndef STRICT -# define STRICT -# endif -# include <windows.h> -# include <process.h> -# endif /* ndef FEATURE_PTHREAD */ - -# include "win32.h" -# ifndef _WIN_CONSOLE -# include "w32log.h" -# endif /* ndef _WIN_CONSOLE */ -# include "w32svrapi.h" - -#else /* ifndef _WIN32 */ - -# if !defined (__OS2__) -# include <unistd.h> -# include <sys/wait.h> -# endif /* ndef __OS2__ */ -# include <sys/time.h> -# include <sys/stat.h> -# include <sys/ioctl.h> - -#ifdef sun -#include <sys/termios.h> -#endif /* sun */ - -#ifdef unix -#include <pwd.h> -#include <grp.h> -#endif - -# include <signal.h> - -# ifdef __BEOS__ -# include <socket.h> /* BeOS has select() for sockets only. */ -# include <OS.h> /* declarations for threads and stuff. */ -# endif - -# if defined(__EMX__) || defined(__OS2__) -# include <sys/select.h> /* OS/2/EMX needs a little help with select */ -# endif -# ifdef __OS2__ -#define INCL_DOS -# include <os2.h> -#define bzero(B,N) memset(B,0x00,n) -# endif - -# ifndef FD_ZERO -# include <select.h> -# endif - -#endif - -#include "project.h" -#include "list.h" -#include "jcc.h" -#include "filters.h" -#include "loaders.h" -#include "parsers.h" -#include "miscutil.h" -#include "errlog.h" -#include "jbsockets.h" -#include "gateway.h" -#include "actions.h" -#include "cgi.h" -#include "loadcfg.h" -#include "urlmatch.h" - -const char jcc_h_rcs[] = JCC_H_VERSION;

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.

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 - * - * - *********************************************************************/ - - -#include "config.h" - -#include <stdio.h> -#include <sys/types.h> -#include <stdlib.h> -#include <string.h> -#include <signal.h> -#include <fcntl.h> -#include <errno.h> -#include <ctype.h> -#include <assert.h> - -#ifdef _WIN32 - -# ifndef STRICT -# define STRICT -# endif -# include <windows.h> - -# include "win32.h" -# ifndef _WIN_CONSOLE -# include "w32log.h" -# endif /* ndef _WIN_CONSOLE */ - -#else /* ifndef _WIN32 */ - -#ifndef __OS2__ -# include <unistd.h> -# include <sys/wait.h> -#endif -# include <sys/time.h> -# include <sys/stat.h> -# include <signal.h> - -#endif - -#include "loadcfg.h" -#include "list.h" -#include "jcc.h" -#include "filters.h" -#include "loaders.h" -#include "miscutil.h" -#include "errlog.h" -#include "ssplit.h" -#include "encode.h" -#include "urlmatch.h" -#include "cgi.h" -#include "gateway.h" - -const char loadcfg_h_rcs[] = LOADCFG_H_VERSION; - -/* - * Fix a problem with Solaris.

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 - * IJB now changes HTTP/1.1 to HTTP/1.0 in requests and answers. - * - * Revision 1.29 2001/09/24 21:09:24 jongfoster - * Fixing 2 memory leaks that Guy spotted, where the paramater to - * enlist() was not being free()d. - * - * Revision 1.28 2001/09/22 16:32:28 jongfoster - * Removing unused #includes. - * - * Revision 1.27 2001/09/20 15:45:25 steudten - * - * add casting from size_t to int for printf() - * remove local variable shadow s2 - * - * Revision 1.26 2001/09/16 17:05:14 jongfoster - * Removing unused #include showarg.h - * - * Revision 1.25 2001/09/16 13:21:27 jongfoster - * Changes to use new list functions. - * - * 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 - * - * Revision 1.21 2001/07/31 14:46:00 oes - * - Persistant connections now suppressed - * - sed() no longer appends empty header to csp->headers - * - * Revision 1.20 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 1.19 2001/07/25 17:21:54 oes - * client_uagent now saves copy of User-Agent: header value - * - * Revision 1.18 2001/07/13 14:02:46 oes - * - Included fix to repair broken HTTP requests that - * don't contain a path, not even '/'. - * - Removed all #ifdef PCRS - * - content_type now always inspected and classified as - * text, gif or other. - * - formatting / comments - * - * Revision 1.17 2001/06/29 21:45:41 oes - * Indentation, CRLF->LF, Tab-> Space - * - * Revision 1.16 2001/06/29 13:32:42 oes - * - Fixed a comment - * - Adapted free_http_request - * - Removed logentry from cancelled commit - * - * Revision 1.15 2001/06/03 19:12:38 oes - * 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 - * - * - *********************************************************************/ - - -#include "config.h" - -#ifndef _WIN32 -#include <stdio.h> -#include <sys/types.h> -#endif - -#include <stdlib.h> -#include <ctype.h> -#include <assert.h> -#include <string.h> - -#ifdef __GLIBC__ -/* - * Convince GNU's libc to provide a strptime prototype. - */ -#define __USE_XOPEN -#endif /*__GLIBC__ */ -#include <time.h> - -#ifdef FEATURE_ZLIB -#include <zlib.h> -#endif - -#if !defined(_WIN32) && !defined(__OS2__) -#include <unistd.h> -#endif - -#include "project.h" - -#ifdef FEATURE_PTHREAD -#include "jcc.h" -/* jcc.h is for mutex semapores only */ -#endif /* def FEATURE_PTHREAD */ -#include "list.h" -#include "parsers.h" -#include "ssplit.h" -#include "errlog.h" -#include "jbsockets.h" -#include "miscutil.h" -#include "list.h" -#include "actions.h" -#include "filters.h" - -#ifndef HAVE_STRPTIME -#include "strptime.h" -#endif - -const char parsers_h_rcs[] = PARSERS_H_VERSION; - -/* Fix a problem with Solaris.

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. - -**** diff --git a/external/privoxy/pcre/doc/NON-UNIX-USE b/external/privoxy/pcre/doc/NON-UNIX-USE deleted file mode 100644 index 09a7432..0000000 --- a/external/privoxy/pcre/doc/NON-UNIX-USE +++ /dev/null @@ -1,50 +0,0 @@ -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.

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.

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.

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.

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.

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. - -.SH AUTHOR -Philip Hazel <ph10(a)cam.ac.uk> -.br -University Computing Service, -.br -New Museums Site, -.br -Cambridge CB2 3QG, England. -.br -Phone: +44 1223 334714 - -Last updated: 28 August 2000, -.br - the 250th anniversary of the death of J.S.

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>.

For example, if the pattern -</P> -<P> -<PRE> - a?b? -</PRE> -</P> -<P> -is applied to a string not beginning with "a" or "b", it matches the empty -string at the start of the subject. With PCRE_NOTEMPTY set, this match is not -valid, so PCRE searches further into the string for occurrences of "a" or "b". -</P> -<P> -Perl has no direct equivalent of PCRE_NOTEMPTY, but it does make a special case -of a pattern match of the empty string within its <B>split()</B> function, and -when using the /g modifier. It is possible to emulate Perl's behaviour after -matching a null string by first trying the match again at the same offset with -PCRE_NOTEMPTY set, and then if that fails by advancing the starting offset (see -below) and trying an ordinary match again. -</P> -<P> -The subject string is passed as a pointer in <I>subject</I>, a length in -<I>length</I>, and a starting offset in <I>startoffset</I>. Unlike the pattern -string, it may contain binary zero characters. When the starting offset is -zero, the search for a match starts at the beginning of the subject, and this -is by far the most common case. -</P> -<P> -A non-zero starting offset is useful when searching for another match in the -same subject by calling <B>pcre_exec()</B> again after a previous success. -Setting <I>startoffset</I> differs from just passing over a shortened string and -setting PCRE_NOTBOL in the case of a pattern that begins with any kind of -lookbehind. For example, consider the pattern -</P> -<P> -<PRE> - \Biss\B -</PRE> -</P> -<P> -which finds occurrences of "iss" in the middle of words. (\B matches only if -the current position in the subject is not a word boundary.) When applied to -the string "Mississipi" the first call to <B>pcre_exec()</B> finds the first -occurrence. If <B>pcre_exec()</B> is called again with just the remainder of the -subject, namely "issipi", it does not match, because \B is always false at the -start of the subject, which is deemed to be a word boundary. However, if -<B>pcre_exec()</B> is passed the entire string again, but with <I>startoffset</I> -set to 4, it finds the second occurrence of "iss" because it is able to look -behind the starting point to discover that it is preceded by a letter. -</P> -<P> -If a non-zero starting offset is passed when the pattern is anchored, one -attempt to match at the given offset is tried. This can only succeed if the -pattern does not require the match to be at the start of the subject. -</P> -<P> -In general, a pattern matches a certain portion of the subject, and in -addition, further substrings from the subject may be picked out by parts of the -pattern. Following the usage in Jeffrey Friedl's book, this is called -"capturing" in what follows, and the phrase "capturing subpattern" is used for -a fragment of a pattern that picks out a substring. PCRE supports several other -kinds of parenthesized subpattern that do not cause substrings to be captured. -</P> -<P> -Captured substrings are returned to the caller via a vector of integer offsets -whose address is passed in <I>ovector</I>. The number of elements in the vector -is passed in <I>ovecsize</I>. The first two-thirds of the vector is used to pass -back captured substrings, each substring using a pair of integers. The -remaining third of the vector is used as workspace by <B>pcre_exec()</B> while -matching capturing subpatterns, and is not available for passing back -information. The length passed in <I>ovecsize</I> should always be a multiple of -three. If it is not, it is rounded down. -</P> -<P> -When a match has been successful, information about captured substrings is -returned in pairs of integers, starting at the beginning of <I>ovector</I>, and -continuing up to two-thirds of its length at the most. The first element of a -pair is set to the offset of the first character in a substring, and the second -is set to the offset of the first character after the end of a substring. The -first pair, <I>ovector[0]</I> and <I>ovector[1]</I>, identify the portion of the -subject string matched by the entire pattern. The next pair is used for the -first capturing subpattern, and so on. The value returned by <B>pcre_exec()</B> -is the number of pairs that have been set. If there are no capturing -subpatterns, the return value from a successful match is 1, indicating that -just the first pair of offsets has been set. -</P> -<P> -Some convenience functions are provided for extracting the captured substrings -as separate strings. These are described in the following section. -</P> -<P> -It is possible for an capturing subpattern number <I>n+1</I> to match some -part of the subject when subpattern <I>n</I> has not been used at all. For -example, if the string "abc" is matched against the pattern (a|(z))(bc) -subpatterns 1 and 3 are matched, but 2 is not. When this happens, both offset -values corresponding to the unused subpattern are set to -1. -</P> -<P> -If a capturing subpattern is matched repeatedly, it is the last portion of the -string that it matched that gets returned. -</P> -<P> -If the vector is too small to hold all the captured substrings, it is used as -far as possible (up to two-thirds of its length), and the function returns a -value of zero. In particular, if the substring offsets are not of interest, -<B>pcre_exec()</B> may be called with <I>ovector</I> passed as NULL and -<I>ovecsize</I> as zero. However, if the pattern contains back references and -the <I>ovector</I> isn't big enough to remember the related substrings, PCRE has -to get additional memory for use during matching. Thus it is usually advisable -to supply an <I>ovector</I>. -</P> -<P> -Note that <B>pcre_info()</B> can be used to find out how many capturing -subpatterns there are in a compiled pattern. The smallest size for -<I>ovector</I> that will allow for <I>n</I> captured substrings in addition to -the offsets of the substring matched by the whole pattern is (<I>n</I>+1)*3. -</P> -<P> -If <B>pcre_exec()</B> fails, it returns a negative number.

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.

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.

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.

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.

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.

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.

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 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.

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.

Thus the two patterns -</P> -<P> -<PRE> - (?i:saturday|sunday) - (?:(?i)saturday|sunday) -</PRE> -</P> -<P> -match exactly the same set of strings.

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.

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".

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.

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.

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.

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.

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.

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.

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.

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. - - - -AUTHOR - Philip Hazel <ph10(a)cam.ac.uk> - University Computing Service, - New Museums Site, - Cambridge CB2 3QG, England. - Phone: +44 1223 334714 - - Last updated: 28 August 2000, - the 250th anniversary of the death of J.S.

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.

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.

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.

You can use "make install" to copy these, and the public header file -pcre.h, to appropriate live directories on your system, in the normal way. - -Running "make install" also installs the command pcre-config, which can be used -to recall information about the PCRE configuration and installation. For -example, - - pcre-config --version - -prints the version number, and - - pcre-config --libs - -outputs information about where the library is installed. This command can be -included in makefiles for programs that use PCRE, saving the programmer from -having to remember too many details. - - -Shared libraries on Unix systems --------------------------------- - -The default distribution builds PCRE as two shared libraries. This support is -new and experimental and may not work on all systems. It relies on the -"libtool" scripts - these are distributed with PCRE. It should build a -"libtool" script and use this to compile and link shared libraries, which are -placed in a subdirectory called .libs. The programs pcretest and pcregrep are -built to use these uninstalled libraries by means of wrapper scripts. When you -use "make install" to install shared libraries, pcregrep and pcretest are -automatically re-built to use the newly installed libraries. However, only -pcregrep is installed, as pcretest is really just a test program. - -To build PCRE using static libraries you must use --disable-shared when -configuring it. For example - -./configure --prefix=/usr/gnu --disable-shared - -Then run "make" in the usual way. - - -Building on non-Unix systems ----------------------------- - -For a non-Unix system, read the comments in the file NON-UNIX-USE. PCRE has -been compiled on Windows systems and on Macintoshes, but I don't know the -details because I don't use those systems. It should be straightforward to -build PCRE on any system that has a Standard C compiler, because it uses only -Standard C functions. - - -Testing PCRE ------------- - -To test PCRE on a Unix system, run the RunTest script in the pcre directory. -(This can also be run by "make runtest", "make check", or "make test".) For -other systems, see the instruction in NON-UNIX-USE. - -The script runs the pcretest test program (which is documented in -doc/pcretest.txt) on each of the testinput files (in the testdata directory) in -turn, and compares the output with the contents of the corresponding testoutput -file. A file called testtry is used to hold the output from pcretest. To run -pcretest on just one of the test files, give its number as an argument to -RunTest, for example: - - RunTest 3 - -The first and third test files can also be fed directly into the perltest -script to check that Perl gives the same results. The third file requires the -additional features of release 5.005, which is why it is kept separate from the -main test input, which needs only Perl 5.004. In the long run, when 5.005 (or -higher) is widespread, these two test files may get amalgamated. - -The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(), -pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error -detection, and run-time flags that are specific to PCRE, as well as the POSIX -wrapper API. It also uses the debugging flag to check some of the internals of -pcre_compile(). - -If you build PCRE with a locale setting that is not the standard C locale, the -character tables may be different (see next paragraph). In some cases, this may -cause failures in the second set of tests. For example, in a locale where the -isprint() function yields TRUE for characters in the range 128-255, the use of -[:isascii:] inside a character class defines a different set of characters, and -this shows up in this test as a difference in the compiled code, which is being -listed for checking. Where the comparison test output contains [\x00-\x7f] the -test will contain [\x00-\xff], and similarly in some other cases. This is not a -bug in PCRE. - -The fourth set of tests checks pcre_maketables(), the facility for building a -set of character tables for a specific locale and using them instead of the -default tables. The tests make use of the "fr" (French) locale. Before running -the test, the script checks for the presence of this locale by running the -"locale" command. If that command fails, or if it doesn't include "fr" in the -list of available locales, the fourth test cannot be run, and a comment is -output to say why. If running this test produces instances of the error - - ** Failed to set locale "fr" - -in the comparison output, it means that locale is not available on your system, -despite being listed by "locale". This does not mean that PCRE is broken. - -The fifth test checks the experimental, incomplete UTF-8 support. It is not run -automatically unless PCRE is built with UTF-8 support. This file can be fed -directly to the perltest8 script, which requires Perl 5.6 or higher. The sixth -file tests internal UTF-8 features of PCRE that are not relevant to Perl. - - -Character tables ----------------- - -PCRE uses four tables for manipulating and identifying characters. The final -argument of the pcre_compile() function is a pointer to a block of memory -containing the concatenated tables. A call to pcre_maketables() can be used to -generate a set of tables in the current locale. If the final argument for -pcre_compile() is passed as NULL, a set of default tables that is built into -the binary is used. - -The source file called chartables.c contains the default set of tables. This is -not supplied in the distribution, but is built by the program dftables -(compiled from dftables.c), which uses the ANSI C character handling functions -such as isalnum(), isalpha(), isupper(), islower(), etc. to build the table -sources. This means that the default C locale which is set for your system will -control the contents of these default tables. You can change the default tables -by editing chartables.c and then re-building PCRE. If you do this, you should -probably also edit Makefile to ensure that the file doesn't ever get -re-generated. - -The first two 256-byte tables provide lower casing and case flipping functions, -respectively. The next table consists of three 32-byte bit maps which identify -digits, "word" characters, and white space, respectively. These are used when -building 32-byte bit maps that represent character classes. - -The final 256-byte table has bits indicating various character types, as -follows: - - 1 white space character - 2 letter - 4 decimal digit - 8 hexadecimal digit - 16 alphanumeric or '_' - 128 regular expression metacharacter or binary zero - -You should not alter the set of characters that contain the 128 bit, as that -will cause PCRE to malfunction. - - -Manifest --------- - -The distribution should contain the following files: - -(A) The actual source files of the PCRE library functions and their - headers: - - dftables.c auxiliary program for building chartables.c - get.c ) - maketables.c ) - study.c ) source of - pcre.c ) the functions - pcreposix.c ) - pcre.in "source" for the header for the external API; pcre.h - is built from this by "configure" - pcreposix.h header for the external POSIX wrapper API - internal.h header for internal use - config.in template for config.h, which is built by configure - -(B) Auxiliary files: - - AUTHORS information about the author of PCRE - ChangeLog log of changes to the code - INSTALL generic installation instructions - LICENCE conditions for the use of PCRE - COPYING the same, using GNU's standard name - Makefile.in template for Unix Makefile, which is built by configure - NEWS important changes in this release - NON-UNIX-USE notes on building PCRE on non-Unix systems - README this file - RunTest.in template for a Unix shell script for running tests - config.guess ) files used by libtool, - config.sub ) used only when building a shared library - configure a configuring shell script (built by autoconf) - configure.in the autoconf input used to build configure - doc/Tech.Notes notes on the encoding - doc/pcre.3 man page source for the PCRE functions - doc/pcre.html HTML version - doc/pcre.txt plain text version - doc/pcreposix.3 man page source for the POSIX wrapper API - doc/pcreposix.html HTML version - doc/pcreposix.txt plain text version - doc/pcretest.txt documentation of test program - doc/perltest.txt documentation of Perl test program - doc/pcregrep.1 man page source for the pcregrep utility - doc/pcregrep.html HTML version - doc/pcregrep.txt plain text version - install-sh a shell script for installing files - ltconfig ) files used to build "libtool", - ltmain.sh ) used only when building a shared library - pcretest.c test program - perltest Perl test program - perltest8 Perl test program for UTF-8 tests - pcregrep.c source of a grep utility that uses PCRE - pcre-config.in source of script which retains PCRE information - testdata/testinput1 test data, compatible with Perl 5.004 and 5.005 - testdata/testinput2 test data for error messages and non-Perl things - testdata/testinput3 test data, compatible with Perl 5.005 - testdata/testinput4 test data for locale-specific tests - testdata/testinput5 test data for UTF-8 tests compatible with Perl 5.6 - testdata/testinput6 test data for other UTF-8 tests - testdata/testoutput1 test results corresponding to testinput1 - testdata/testoutput2 test results corresponding to testinput2 - testdata/testoutput3 test results corresponding to testinput3 - testdata/testoutput4 test results corresponding to testinput4 - testdata/testoutput5 test results corresponding to testinput5 - testdata/testoutput6 test results corresponding to testinput6 - -(C) Auxiliary files for Win32 DLL - - dll.mk - pcre.def - -Philip Hazel <ph10(a)cam.ac.uk> -August 2000 diff --git a/external/privoxy/pcre/get.c b/external/privoxy/pcre/get.c deleted file mode 100644 index 42e9bd4..0000000 --- a/external/privoxy/pcre/get.c +++ /dev/null @@ -1,227 +0,0 @@ -/************************************************* -* Perl-Compatible Regular Expressions * -*************************************************/ - -/* -This is a library of functions to support regular expressions whose syntax -and semantics are as close as possible to those of the Perl 5 language.

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. diff --git a/external/privoxy/pcre/install-sh b/external/privoxy/pcre/install-sh deleted file mode 100644 index e9de238..0000000 --- a/external/privoxy/pcre/install-sh +++ /dev/null @@ -1,251 +0,0 @@ -#!/bin/sh -# -# install - install a program, script, or datafile -# This comes from X11R5 (mit/util/scripts/install.sh). -# -# Copyright 1991 by the Massachusetts Institute of Technology -# -# Permission to use, copy, modify, distribute, and sell this software and its -# documentation for any purpose is hereby granted without fee, provided that -# the above copyright notice appear in all copies and that both that -# copyright notice and this permission notice appear in supporting -# documentation, and that the name of M.I.T. not be used in advertising or -# publicity pertaining to distribution of the software without specific, -# written prior permission.

Incorporated many - suggestions from Jan "Yenya" Kasprzak <kas(a)fi.muni.cz> for the - spec file. Fixed logging problem and since runlevel 2 does not - use networking, I replaced /etc/rc.d/rc2.d/S84junkbuster with - /etc/rc.d/rc2.d/K09junkbuster thanks to Shaw Walker - <walker(a)netgate.net>. You should now be able to build this RPM as - a non-root user (mathias(a)weidner.sem.lipsia.de) - -* Sun Jan 31 1999 Stefan Waldherr <stefan(a)waldherr.org> - %%{_localstatedir}/log/junkbuster set to nobody. Added /etc/junkbuster/imagelist - to allow more sophisticated matching of blocked images. Logrotate - logfile. Added files for auto-updating the blocklist et al. - -* Wed Dec 16 1998 Stefan Waldherr <stefan(a)waldherr.org> - Configure blank version via config file. No separate blank - version anymore. Added Roland's <roland(a)spinnaker.rhein.de> - patch to show a logo instead of a blank area. Added a suggestion - from Alex <alex(a)cocoa.demon.co.uk>: %%{_localstatedir}/lock/subsys/junkbuster. - More regexps in the blocklist. Prepared the forwardfile for - squid. Extended image regexp with help from gabriel - <somlo(a)CS.ColoState.EDU>. - -* Thu Nov 19 1998 Stefan Waldherr <stefan(a)waldherr.org> - All RPMs now identify themselves in the show-proxy-args page. - Released Windoze version. Run junkbuster as nobody instead of - root. - -* Fri Oct 30 1998 Stefan Waldherr <stefan(a)waldherr.org> - Newest version. First release (hence the little version number - mixture -- 2.0.2-0 instead of 2.0-7). This version tightens - security over 2.0.1; some multi-user sites will need to change - the listen-address in the configuration file. The blank version of - the Internet Junkbuster has a more sophisticated way of replacing - images. All RPMs identify themselves in the show-proxy-args page. - -* Thu Sep 23 1998 Stefan Waldherr <stefan(a)waldherr.org> - Modified the blocking feature, so that only GIFs and JPEGs are - blocked and replaced but not HTML pages. Thanks to - "Gerd Flender" <plgerd(a)informatik.uni-siegen.de> for this nice - idea. Added numerous stuff to the blocklist. Keep patches in - seperate files and no longer in diffs (easier to maintain). - -* Tue Jun 16 1998 Stefan Waldherr <swa(a)cs.cmu.edu> - Moved config files to /etc/junkbuster directory, moved man page, - added BuildRoot directive (Thanks to Alexey Nogin <ayn2(a)cornell.edu>) - Made new version junkbuster-raw (which is only a stripped version of - the junkuster rpm, i.e. without my blocklist, etc.) - -* Tue Jun 16 1998 (2.0-1) - Uhm, not that much. Just a new junkbuster version that - fixes a couple of bugs ... and of course a bigger - blocklist with the unique Now-less-ads-than-ever(SM) - feature. - Oh, one thing: I changed the default user agent to Linux -- no - need anymore to support Apple. - -* Tue Jun 16 1998 (2.0-0) - Now-less-ads-than-ever (SM) - compiled with gcc instead of cc - compiled with -O3, thus it should be a little faster - show-proxy-args now works - /etc/junkbuster.init wasn't necessary - -* Tue Jun 16 1998 (1.4) - some more config files were put into /etc - The junkbuster-blank rpm returns a 1x1 pixel image, that gets - displayed by Netscape instead of the blocked image. - Read http://www.waldherr.org/junkbuster/ for - further info. - -* Tue Jun 16 1998 (1.3) - The program has been moved to /usr/sbin (from /usr/local/bin) - Init- and stopscripts (/etc/rc.d/rc*) have been added so - that the junkbuster starts automatically during bootup. - The /etc/blocklist file is much more sophisticated. Theoretically - one should e.g. browse all major US and German newspapers without - seeing one annoying ad. - junkbuster.init was modified. It now starts junkbuster with an - additional "-r @" flag. - -# $Log: privoxy-rh.spec,v $ -# Revision 1.63 2009/03/21 10:46:15 fabiankeil -# Bump version to 3.0.12. -# -# Revision 1.62 2009/02/15 17:17:23 fabiankeil -# - Bump version to 3.0.11. -# - List match-all.action as %config file. -# -# Revision 1.61 2009/01/13 16:47:34 fabiankeil -# The standard.action file is gone. -# -# Revision 1.60 2008/08/30 12:46:49 fabiankeil -# The jarfile directive is gone.

Privoxy has a -flexible configuration and can be customized to suit individual needs and tastes. -It has application for both stand-alone systems and multi-user networks. -.PP -Privoxy is Free Software and licensed under the GPL2. -.SH "INSTALLATION AND USAGE" -.PP -Browsers can either be individually configured to use -\fBPrivoxy\fR as a HTTP proxy (recommended), -or \fBPrivoxy\fR can be combined with a packet -filter to build an intercepting proxy -(see \fIconfig\fR). The default setting is for -localhost, on port 8118 (configurable in the main config file). To set the -HTTP proxy in Firefox, go through: \fBTools\fR; -\fBOptions\fR; \fBGeneral\fR; -\fBConnection Settings\fR; -\fBManual Proxy Configuration\fR. -.PP -For Internet Explorer, go through: \fBTools\fR; -\fBInternet Properties\fR; \fBConnections\fR; -\fBLAN Settings\fR. -.PP -The Secure (SSL) Proxy should also be set to the same values, otherwise -https: URLs will not be proxied. Note: \fBPrivoxy\fR can only -proxy HTTP and HTTPS traffic. Do not try it with FTP or other protocols. -HTTPS presents some limitations, and not all features will work with HTTPS -connections. -.PP -For other browsers, check the documentation. -.SH "CONFIGURATION" -.PP -\fBPrivoxy\fR can be configured with the various configuration -files. The default configuration files are: \fIconfig\fR, -\fIdefault.filter\fR, \fIdefault.action\fR and -\fIdefault.action\fR. \fIuser.action\fR should -be used for locally defined exceptions to the default rules in -\fImatch-all.action\fR and \fIdefault.action\fR, -and \fIuser.filter\fR for locally defined filters. These are -well commented. On Unix and Unix-like systems, these are located in -\fI/etc/privoxy/\fR by default. -.PP -\fBPrivoxy\fR uses the concept of \fBactions\fR -in order to manipulate the data stream between the browser and remote sites. -There are various actions available with specific functions for such things -as blocking web sites, managing cookies, etc. These actions can be invoked -individually or combined, and used against individual URLs, or groups of URLs -that can be defined using wildcards and regular expressions. The result is -that the user has greatly enhanced control and freedom. -.PP -The actions list (ad blocks, etc) can also be configured with your -web browser at http://config.privoxy.org/ -(assuming the configuration allows it). -\fBPrivoxy's\fR configuration parameters can also be viewed at -the same page. In addition, \fBPrivoxy\fR can be toggled on/off. -This is an internal page, and does not require Internet access. -.PP -See the \fIUser Manual\fR for a detailed -explanation of installation, general usage, all configuration options, new -features and notes on upgrading. -.SH "FILES" - -.nf - - \fI/usr/sbin/privoxy\fR - \fI/etc/privoxy/config\fR - \fI/etc/privoxy/match-all.action\fR - \fI/etc/privoxy/default.action\fR - \fI/etc/privoxy/user.action\fR - \fI/etc/privoxy/default.filter\fR - \fI/etc/privoxy/user.filter\fR - \fI/etc/privoxy/trust\fR - \fI/etc/privoxy/templates/*\fR - \fI/var/log/privoxy/logfile\fR -.fi -.PP -Various other files should be included, but may vary depending on platform -and build configuration. Additional documentation should be included in the local -documentation directory. -.SH "SIGNALS" -.PP -\fBPrivoxy\fR terminates on the \fBSIGINT\fR, -\fBSIGTERM\fR and \fBSIGABRT\fR signals. Log -rotation scripts may cause a re-opening of the logfile by sending a -\fBSIGHUP\fR to \fBPrivoxy\fR. Note that unlike -other daemons, \fBPrivoxy\fR does not need to be made aware of -config file changes by \fBSIGHUP\fR -- it will detect them -automatically. -.SH "NOTES" -.PP -Please see the \fIUser Manual\fR on how to contact the -developers, for feature requests, reporting problems, and other questions. -.SH "SEE ALSO" -.PP -Other references and sites of interest to \fBPrivoxy\fR -users: -.PP - -http://www.privoxy.org/, -the \fBPrivoxy\fR Home page. - -http://www.privoxy.org/faq/, -the \fBPrivoxy\fR FAQ. - -http://www.privoxy.org/developer-manual/, -the \fBPrivoxy\fR developer manual. - -https://sourceforge.net/projects/ijbswa/, -the Project Page for \fBPrivoxy\fR on -SourceForge. - -http://config.privoxy.org/, -the web-based user interface. \fBPrivoxy\fR must be -running for this to work.

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.

This is - * used for the socket file descriptors. On Windows, this - * is SOCKET (a typedef for unsigned). Everywhere else, it's - * an int.

(i.e. ijb-send-banner uses this) - * - Implemented show-url-info interceptor. (Which is why I needed - * the above interceptors changes - a typical URL is - * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif". - * The previous mechanism would not have intercepted that, and - * if it had been intercepted then it then it would have replaced - * it with an image.) - * - * Revision 1.6 2001/05/27 22:17:04 oes - * - * - re_process_buffer no longer writes the modified buffer - * to the client, which was very ugly. It now returns the - * buffer, which it is then written by chat. - * - * - content_length now adjusts the Content-Length: header - * for modified documents rather than crunch()ing it. - * (Length info in csp->content_length, which is 0 for - * unmodified documents) - * - * - For this to work, sed() is called twice when filtering. - * - * Revision 1.5 2001/05/26 00:28:36 jongfoster - * Automatic reloading of config file. - * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32). - * Most of the global variables have been moved to a new - * struct configuration_spec, accessed through csp->config->globalname - * Most of the globals remaining are used by the Win32 GUI. - * - * Revision 1.4 2001/05/22 18:46:04 oes - * - * - Enabled filtering banners by size rather than URL - * by adding patterns that replace all standard banner - * sizes with the "Junkbuster" gif to the re_filterfile - * - * - Enabled filtering WebBugs by providing a pattern - * which kills all 1x1 images - * - * - Added support for PCRE_UNGREEDY behaviour to pcrs, - * which is selected by the (nonstandard and therefore - * capital) letter 'U' in the option string. - * It causes the quantifiers to be ungreedy by default. - * Appending a ? turns back to greedy (!). - * - * - Added a new interceptor ijb-send-banner, which - * sends back the "Junkbuster" gif. Without imagelist or - * MSIE detection support, or if tinygif = 1, or the - * URL isn't recognized as an imageurl, a lame HTML - * explanation is sent instead. - * - * - Added new feature, which permits blocking remote - * script redirects and firing back a local redirect - * to the browser. - * The feature is conditionally compiled, i.e. it - * can be disabled with --disable-fast-redirects, - * plus it must be activated by a "fast-redirects" - * line in the config file, has its own log level - * and of course wants to be displayed by show-proxy-args - * Note: Boy, all the #ifdefs in 1001 locations and - * all the fumbling with configure.in and acconfig.h - * were *way* more work than the feature itself :-( - * - * - Because a generic redirect template was needed for - * this, tinygif = 3 now uses the same. - * - * - Moved GIFs, and other static HTTP response templates - * to project.h - * - * - Some minor fixes - * - * - Removed some >400 CRs again (Jon, you really worked - * a lot! ;-) - * - * Revision 1.3 2001/05/20 01:21:20 jongfoster - * Version 2.9.4 checkin. - * - Merged popupfile and cookiefile, and added control over PCRS - * filtering, in new "actionsfile". - * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration - * file error you now get a message box (in the Win32 GUI) rather - * than the program exiting with no explanation. - * - Made killpopup use the PCRS MIME-type checking and HTTP-header - * skipping. - * - Removed tabs from "config" - * - Moved duplicated url parsing code in "loaders.c" to a new funcition. - * - Bumped up version number. - * - * Revision 1.2 2001/05/17 23:01:01 oes - * - Cleaned CRLF's from the sources and related files - * - * Revision 1.1.1.1 2001/05/15 13:59:03 oes - * Initial import of version 2.9.3 source tree - * - * - *********************************************************************/ - - -/* Declare struct FILE for vars and funcs. */ -#include <stdio.h> - -/* Need time_t for file_list */ -#include <time.h> -/* Needed for pcre choice */ -#include "config.h" - -/* - * Include appropriate regular expression libraries. - * Note that pcrs and pcre (native) are needed for cgi - * and are included anyway. - */ - -#ifdef STATIC_PCRE -# include "pcre.h" -#else -# ifdef PCRE_H_IN_SUBDIR -# include <pcre/pcre.h> -# else -# include <pcre.h> -# endif -#endif - -#ifdef STATIC_PCRS -# include "pcrs.h" -#else -# include <pcrs.h> -#endif - -#ifdef STATIC_PCRE -# include "pcreposix.h" -#else -# ifdef PCRE_H_IN_SUBDIR -# include <pcre/pcreposix.h> -# else -# include <pcreposix.h> -# endif -#endif - -#ifdef AMIGA -#include "amiga.h" -#endif /* def AMIGA */ - -#ifdef _WIN32 -/* - * I don't want to have to #include all this just for the declaration - * of SOCKET.

For example for -"debug 64" B<privoxy-log-parser> will (by default) only show messages that -affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser> -will hide the "filter foo caused 0 hits" message. - -=head1 OPTIONS - -[B<--accept-unknown-messages>] Don't print warnings in case of unknown messages, -just don't highlight them. - -[B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is -omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active. -This option is only intended to make embedding log excerpts in web pages easier. -It does not excape any input! - -[B<--no-msecs>] Don't expect milisecond resolution - -[B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when -the filtered output is piped into less in which case the ANSI control -codes don't work, or if the terminal itself doesn't support the control -codes. - -[B<--show-ineffective-filters>] Don't suppress log lines for filters -that didn't modify the content. - -[B<--version>] Print version and exit. - -=head1 EXAMPLES - -To monitor a log file: - -tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser> - -Replace '-F' with '-f' if your tail implementation lacks '-F' support -or if the log won't get rotated anyway. The log file location depends -on your system (Doh!). - -To monitor Privoxy without having it write to a log file: - -privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser> - -Again, the config file location depends on your system. Output redirection -depends on your shell, the above works with bourne shells. - -To read a processed Privoxy log file from top to bottom, letting the content -scroll by slightly faster than you can read: - -B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log - -This is probably only useful to fill screens in the background of haxor movies. - -=head1 CAVEATS - -Syntax highlighting with ANSI escape sequences will look strange -if your background color isn't black. - -Some messages aren't recognized yet and will not be fully highlighted. - -B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind, -using earlier Privoxy versions will probably result in an increased amount -of unrecognized log lines. - -Privoxy's log files tend to be rather large. If you use HTML -highlighting some browsers can't handle them, get confused and -will eventually crash because of segmentation faults or unexpected -exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s -fault. - -=head1 BUGS - -Many settings can't be controlled through command line options yet. - -=head1 SEE ALSO - -privoxy(1) - -=head1 AUTHOR - -Fabian Keil <fk(a)fabiankeil.de> - -=cut diff --git a/external/privoxy/tools/privoxy-regression-test.pl b/external/privoxy/tools/privoxy-regression-test.pl deleted file mode 100755 index c7269b7..0000000 --- a/external/privoxy/tools/privoxy-regression-test.pl +++ /dev/null @@ -1,1754 +0,0 @@ -#!/usr/bin/perl - -############################################################################ -# -# Privoxy-Regression-Test -# -# A regression test "framework" for Privoxy.

It's not quite there -yet, however, and can currently only test header actions, -check the returned status code for requests to arbitrary -URLs and verify which actions are applied to them. - -Client header actions are tested by requesting -B<http://p.p/show-request> and checking whether -or not Privoxy modified the original request as expected. - -The original request contains both the header the action-to-be-tested -acts upon and an additional tagger-triggering header that enables -the action to test. - -Applied actions are checked through B<http://p.p/show-url-info>. - -=head1 CONFIGURATION FILE SYNTAX - -Privoxy-Regression-Test's configuration is embedded in -Privoxy action files and loaded through Privoxy's web interface. - -It makes testing a Privoxy version running on a remote system easier -and should prevent you from updating your tests without updating Privoxy's -configuration accordingly. - -A client-header-action test section looks like this: - - # Set Header = Referer: http://www.example.org.zwiebelsuppe.exit/ - # Expect Header = Referer: http://www.example.org/ - {+client-header-filter{hide-tor-exit-notation} -hide-referer} - TAG:^client-header-filter\{hide-tor-exit-notation\}$ - -The example above causes Privoxy-Regression-Test to set -the header B<Referer: http://www.example.org.zwiebelsuppe.exit/> -and to expect it to be modified to -B<Referer: http://www.example.org/>. - -When testing this section, Privoxy-Regression-Test will set the header -B<X-Privoxy-Control: client-header-filter{hide-tor-exit-notation}> -causing the B<privoxy-control> tagger to create the tag -B<client-header-filter{hide-tor-exit-notation}> which will finally -cause Privoxy to enable the action section. - -Note that the actions itself are only used by Privoxy, -Privoxy-Regression-Test ignores them and will be happy -as long as the expectations are satisfied. - -A fetch test looks like this: - - # Fetch Test = http://p.p/user-manual - # Expect Status Code = 302 - -It tells Privoxy-Regression-Test to request B<http://p.p/user-manual> -and to expect a response with the HTTP status code B<302>. Obviously that's -not a very thorough test and mainly useful to get some code coverage -for Valgrind or to verify that the templates are installed correctly. - -If you want to test CGI pages that require a trusted -referer, you can use: - - # Trusted CGI Request = http://p.p/edit-actions - -It works like ordinary fetch tests, but sets the referer -header to a trusted value. - -If no explicit status code expectation is set, B<200> is used. - -To verify that a URL is blocked, use: - - # Blocked URL = http://www.example.com/blocked - -To verify that a specific set of actions is applied to an URL, use: - - # Sticky Actions = +block{foo} +handle-as-empty-document -handle-as-image - # URL = http://www.example.org/my-first-url - -The sticky actions will be checked for all URLs below it -until the next sticky actions directive. - -=head1 TEST LEVELS - -All tests have test levels to let the user -control which ones to execute (see I<OPTIONS> below). -Test levels are either set with the B<Level> directive, -or implicitly through the test type. - -Block tests default to level 7, fetch tests to level 6, -"Sticky Actions" tests default to level 5, tests for trusted CGI -requests to level 3 and client-header-action tests to level 1. - -=head1 OPTIONS - -B<--debug bitmask> Add the bitmask provided as integer -to the debug settings. - -B<--forks forks> Number of forks to start before executing -the regression tests. This is mainly useful for stress-testing. - -B<--fuzzer-address> Listening address used when executing -the regression tests. Useful to make sure that the requests -to load the regression tests don't fail due to fuzzing. - -B<--fuzzer-feeding> Ignore some errors that would otherwise -cause Privoxy-Regression-Test to abort the test because -they shouldn't happen in normal operation. This option is -intended to be used if Privoxy-Regression-Test is only -used to feed a fuzzer in which case there's a high chance -that Privoxy gets an invalid request and returns an error -message. - -B<--help> Shows available command line options. - -B<--header-fuzzing> Modifies linear white space in -headers in a way that should not affect the test result. - -B<--level level> Only execute tests with the specified B<level>. - -B<--loop count> Loop through the regression tests B<count> times. -Useful to feed a fuzzer, or when doing stress tests with -several Privoxy-Regression-Test instances running at the same -time. - -B<--max-level max-level> Only execute tests with a B<level> -below or equal to the numerical B<max-level>. - -B<--max-time max-time> Give Privoxy B<max-time> seconds -to return data. Increasing the default may make sense when -Privoxy is run through Valgrind, decreasing the default may -make sense when Privoxy-Regression-Test is used to feed -a fuzzer. - -B<--min-level min-level> Only execute tests with a B<level> -above or equal to the numerical B<min-level>. - -B<--privoxy-address proxy-address> Privoxy's listening address. -If it's not set, the value of the environment variable http_proxy -will be used. B<proxy-address> has to be specified in http_proxy -syntax. - -B<--retries retries> Retry B<retries> times. - -B<--test-number test-number> Only run the test with the specified -number. - -B<--show-skipped-tests> Log skipped tests even if verbose mode is off. - -B<--verbose> Log succesful and skipped tests. - -B<--version> Print version and exit. - -The second dash is optional, options can be shortened, -as long as there are no ambiguities. - -=head1 PRIVOXY CONFIGURATION - -Privoxy-Regression-Test is shipped with B<regression-tests.action> -which aims to test all official client-header modifying actions -and can be used to verify that the templates and the user manual -files are installed correctly. - -To use it, it has to be copied in Privoxy's configuration -directory, and afterwards referenced in Privoxy's configuration -file with the line: - - actionsfile regression-tests.action - -In general, its tests are supposed to work without changing -any other action files, unless you already added lots of -taggers yourself. If you are using taggers that cause problems, -you might have to temporary disable them for Privoxy's CGI pages. - -Some of the regression tests rely on Privoxy features that -may be disabled in your configuration. Tests with a level below -7 are supposed to work with all Privoxy configurations (provided -you didn't build with FEATURE_GRACEFUL_TERMINATION). - -Tests with level 9 require Privoxy to deliver the User Manual, -tests with level 12 require the CGI editor to be enabled. - -=head1 CAVEATS - -Expect the configuration file syntax to change with future releases. - -=head1 LIMITATIONS - -As Privoxy's B<show-request> page only shows client headers, -Privoxy-Regression-Test can't use it to test Privoxy actions -that modify server headers. - -As Privoxy-Regression-Test relies on Privoxy's tag feature to -control the actions to test, it currently only works with -Privoxy 3.0.7 or later. - -At the moment Privoxy-Regression-Test fetches Privoxy's -configuration page through I<curl>(1), therefore you have to -have I<curl> installed, otherwise you won't be able to run -Privoxy-Regression-Test in a meaningful way. - -=head1 SEE ALSO - -privoxy(1) curl(1) - -=head1 AUTHOR - -Fabian Keil <fk(a)fabiankeil.de> - -=cut diff --git a/external/privoxy/tools/url-pattern-translator.pl b/external/privoxy/tools/url-pattern-translator.pl deleted file mode 100755 index a575333..0000000 --- a/external/privoxy/tools/url-pattern-translator.pl +++ /dev/null @@ -1,139 +0,0 @@ -#!/usr/bin/perl - -############################################################################ -# -# url-pattern-translator -# -# Filters Privoxy action files and changes old-school URL patterns to -# use extended regular expressions for the host as well. -# -# While it works good enough to satisfy the regression tests in -# default.action.master, it isn't perfect and you should double-check -# the output and keep backups of your old action files. -# -# Usage: -# -# url-pattern-translator.pl old.action > new.action -# -# Only convert your files once, or, as RoboCop used to say, -# there will be... trouble. -# -# $Id: url-pattern-translator.pl,v 1.3 2009/01/13 17:01:04 fabiankeil Exp $ -# -# Copyright (c) 2008 Fabian Keil <fk(a)fabiankeil.de> -# -# Permission to use, copy, modify, and distribute this software for any -# purpose with or without fee is hereby granted, provided that the above -# copyright notice and this permission notice appear in all copies. -# -# THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES -# WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF -# MERCHANTABILITY AND FITNESS.

For more -# detail, see http://www.privoxy.org/user-manual/config.html#TRUSTFILE. - -# List trusted domains here. The default is to block any URL that is NOT -# referenced. Access to trusted domains includes all paths within that -# domain. - -# Preceding a domain with a '+' character will designate that domain -# as a "trusted referrer", meaning any requests whose HTTP "Referer" headers -# contain an URL from that domain will be allowed, and the previously untrusted -# host will be dynamically added to this file. Thus, this builds a "white-list" -# of hosts the user is allowed to visit. - -# Note this means that the file will grow with use! - -# Also note that you can only trust referrers if you control the user's -# system and make sure that there are no programs available that allow -# to set arbitrary headers. - -# Preceding the domain with '~' character allows access to that domain only -# (including all paths within that domain), but does not allow access to links -# to other, outside domains. Sites that are added dynamically by trusted -# referrers will include the '~' character, and thus do not become trusted -# referrers themselves. - -# Example: to allow example.com and to white-list domains that appear to -# be reached through links from example.com, uncomment this line: - -# +example.com - -# The next two lines make sure that the user can access Privoxy's -# CGI pages, without automatically trusting their links. - -~config.privoxy.org -~p.p diff --git a/external/privoxy/urlmatch.c b/external/privoxy/urlmatch.c deleted file mode 100644 index 47b607c..0000000 --- a/external/privoxy/urlmatch.c +++ /dev/null @@ -1,1452 +0,0 @@ -const char urlmatch_rcs[] = "$Id: urlmatch.c,v 1.47 2009/03/02 19:18:10 fabiankeil Exp $"; -/********************************************************************* - * - * File : $Source: /cvsroot/ijbswa/current/urlmatch.c,v $ - * - * Purpose : Declares functions to match URLs against URL - * patterns. - * - * Copyright : Written by and Copyright (C) 2001-2009 - * the Privoxy team. http://www.privoxy.org/ - * - * Based on the Internet Junkbuster originally written - * by and Copyright (C) 1997 Anonymous Coders and - * Junkbusters Corporation. http://www.junkbusters.com - * - * 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.

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