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

- * Let the block action take the reason for the block

- *
- * Changed hide-user-agent's default value to "Privoxy VERSION".
- *
- * Changed hide-referrer's default fake value to "http://www.privoxy.org/".

- *
- * Revision 1.22 2006/09/01 17:14:18 hal9
- * Re-ordered the actions list so that they display in the actions editor in

- * name change related issues

- * Revision 1.24 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.23 2002/03/07 03:46:16 oes
- * Fixed compiler warnings
- *
- * Revision 1.22 2002/01/21 00:27:02 jongfoster
- * Allowing free_action(NULL).
- * Moving the functions that #include actionlist.h to the end of the file,
- * because the Visual C++ 97 debugger gets extremely confused if you try
- * to debug any code that comes after them in the file.
- *
- * Revision 1.21 2002/01/17 20:54:44 jongfoster
- * Renaming free_url to free_url_spec, since it frees a struct url_spec.
- *
- * Revision 1.20 2001/11/22 21:56:49 jongfoster
- * Making action_spec->flags into an unsigned long rather than just an
- * unsigned int.
- * Fixing a bug in the display of -add-header and -wafer
- *
- * Revision 1.19 2001/11/13 00:14:07 jongfoster
- * Fixing stupid bug now I've figured out what || means.
- * (It always returns 0 or 1, not one of it's paramaters.)
- *
- * Revision 1.18 2001/11/07 00:06:06 steudten
- * Add line number in error output for lineparsing for
- * actionsfile.
- *
- * Revision 1.17 2001/10/25 03:40:47 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.16 2001/10/23 21:30:30 jongfoster
- * Adding error-checking to selected functions.
- *
- * Revision 1.15 2001/10/14 21:58:22 jongfoster
- * Adding support for the CGI-based editor:
- * - Exported get_actions()
- * - Added new function free_alias_list()
- * - Added support for {{settings}} and {{description}} blocks
- * in the actions file. They are currently ignored.
- * - Added restriction to only one {{alias}} block which must appear
- * first in the file, to simplify the editor's rewriting rules.
- * - Note that load_actions_file() is no longer used by the CGI-based
- * editor, but some of the other routines in this file are.
- *
- * Revision 1.14 2001/09/22 16:36:59 jongfoster
- * Removing unused parameter fs from read_config_line()
- *
- * Revision 1.13 2001/09/16 15:47:37 jongfoster
- * First version of CGI-based edit interface. This is very much a
- * work-in-progress, and you can't actually use it to edit anything
- * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
- * to have any effect.
- *
- * Revision 1.12 2001/09/16 13:21:27 jongfoster
- * Changes to use new list functions.
- *
- * Revision 1.11 2001/09/14 00:17:32 jongfoster

- * Removing unused variable
- *
- * Revision 1.9 2001/07/30 22:08:36 jongfoster

- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.8 2001/06/29 13:19:52 oes
- * Removed logentry from cancelled commit
- *
- * Revision 1.7 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.6 2001/06/07 23:04:34 jongfoster
- * Made get_actions() static.
- *
- * Revision 1.5 2001/06/03 19:11:48 oes
- * adapted to new enlist_unique arg format
- *
- * Revision 1.4 2001/06/01 20:03:42 jongfoster
- * Better memory management - current_action->strings[] now
- * contains copies of the strings, not the original.
- *
- * Revision 1.3 2001/06/01 18:49:17 jongfoster
- * Replaced "list_share" with "list" - the tiny memory gain was not
- * worth the extra complexity.
- *
- * Revision 1.2 2001/05/31 21:40:00 jongfoster
- * Removing some commented out, obsolete blocks of code.
- *
- * Revision 1.1 2001/05/31 21:16:46 jongfoster
- * Moved functions to process the action list into this new file.

- * name change related issues
- *
- * Revision 1.6 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.

- * Adjusted headers for Privoxy's cgi responses:
- * Don't set Last-Modified, Expires and Cache-Control
- * headers for redirects; always set "Connection: close".
- *
- * Revision 1.76 2006/09/07 14:06:38 fabiankeil
- * Only predate the Last-Modified header for cgi responses
- * that are delivered with status code 404 or 503.
- *
- * Revision 1.75 2006/09/07 11:56:39 fabiankeil
- * Mark cgi_send_user_manual as harmless,
- * to fix the access denied problem Hal spotted.
- * The manual has no secret content, therefore we
- * don't have to care about "secure" referrers.
- *
- * Revision 1.74 2006/09/06 18:45:03 fabiankeil
- * Incorporate modified version of Roland Rosenfeld's patch to
- * optionally access the user-manual via Privoxy. Closes patch 679075.
- *
- * Formatting changed to Privoxy style, added call to
- * cgi_error_no_template if the requested file doesn't
- * exist and modified check whether or not Privoxy itself
- * should serve the manual. Should work cross-platform now.
- *
- * Revision 1.73 2006/08/03 02:46:41 david__schmidt
- * Incorporate Fabian Keil's patch work:\rhttp://www.fabiankeil.de/sourcecode/privoxy/
- *
- * Revision 1.72 2006/07/18 14:48:45 david__schmidt
- * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
- * with what was really the latest development (the v_3_0_branch branch)
- *
- * Revision 1.70.2.13 2004/02/17 13:30:23 oes
- * Moved cgi_error_disabled() from cgiedit.c to
- * cgi.c to re-enable build with --disable-editor.
- * Fixes Bug #892744. Thanks to Matthew Fischer
- * for spotting.
- *
- * Revision 1.70.2.12 2003/12/17 16:33:16 oes
- * - Added new function cgi_redirect to handle creation of
- * HTTP redirect messages formerly repeated in the code.
- * - Send cgi_error_disabled instead of cgi_error_404 when
- * referrer check fails
- * - Dynamic content now gets Expires header field with date
- * in the past
- *
- * Revision 1.70.2.11 2003/10/23 12:29:26 oes
- * Bugfix: Transparent PNG was not transparent. Thanks to
- * Dan Razzell of Starfish Systems for notice and new PNG.
- *
- * Revision 1.70.2.10 2003/06/06 07:54:25 oes
- * Security fix: dspatch_known_cgi no longer considers an empty
- * referrer safe for critical CGIs, since malicious links could
- * reside on https:// locations which browsers don't advertize as
- * referrers. Closes bug #749916, thanks to Jeff Epler for the
- * hint. Goodbye One-Click[tm] toggling :-(
- *
- * Revision 1.70.2.9 2003/05/08 15:11:31 oes
- * Nit
- *
- * Revision 1.70.2.8 2003/04/29 13:33:51 oes
- * Killed a compiler warning on OSX
- *
- * Revision 1.70.2.7 2003/04/03 13:50:58 oes
- * - Don't call cgi_error_disabled ifndef FEATURE_CGI_EDIT_ACTIONS
- * (fixes bug #710056)
- * - Show toggle info only if we have it
- *
- * Revision 1.70.2.6 2003/03/12 01:26:25 david__schmidt
- * Move declaration of struct tm dummy outside of a control block so it is
- * accessible later on during snprintf in get_http_time.
- *
- * Revision 1.70.2.5 2003/03/11 11:53:58 oes
- * Cosmetic: Renamed cryptic variable
- *
- * Revision 1.70.2.4 2003/03/07 03:41:03 david__schmidt
- * Wrapping all *_r functions (the non-_r versions of them) with mutex semaphores for OSX. Hopefully this will take care of all of those pesky crash reports.
- *
- * Revision 1.70.2.3 2002/11/28 18:14:32 oes
- * Disable access to critical CGIs via untrusted referrers.
- * This prevents users from being tricked by malicious websites
- * into making unintentional configuration changes:
- *
- * - Added flag to each cgi_dispatcher that allows or denies
- * external linking
- * - Introduced proviorical function that greps for the
- * referrer header before regular header parsing happens
- * - Added safety check to dispatch_known_cgi. CGI is called
- * if (cgi harmless || no referrer || we are referrer).
- * Else a) toggle calls are modified not to change status and
- * b) all other calls are denied.
- *
- * Revision 1.70.2.2 2002/11/12 16:20:37 oes
- * Added missing #ifdef FEATURE_TOGGLE around g_bToggleIJB; fixes bug #636651
- *
- * Revision 1.70.2.1 2002/08/05 11:17:46 oes
- * Fixed Bug #587820, i.e. added workaround for IE bug that includes fragment identifier in (cgi) query
- *
- * Revision 1.70 2002/05/19 11:33:20 jongfoster
- * If a CGI error was not handled, and propogated back to
- * dispatch_known_cgi(), then it was assumed to be "out of memory".
- * This gave a very misleading error message.
- *
- * Now other errors will cause a simple message giving the error
- * number and asking the user to report a bug.
- *
- * Bug report:
- * http://sourceforge.net/tracker/index.php?func=detail

- * Fixes to #include in templates:
- * - Didn't close main file if loading an included template fails.

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

- * name change related issues
- *
- * Revision 1.50 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.49 2002/03/13 00:27:04 jongfoster
- * Killing warnings
- *
- * Revision 1.48 2002/03/08 17:47:07 jongfoster

- *
- * Revision 1.45 2002/03/06 22:54:35 jongfoster
- * Automated function-comment nitpicking.
- *

- *
- * Revision 1.42 2002/01/21 00:33:20 jongfoster
- * Replacing strsav() with the safer string_append() or string_join().

- * - Fixing || bug.
- *
- * Revision 1.37 2001/11/01 14:28:47 david__schmidt
- * Show enablement/disablement status in almost all templates.
- * There is a little trickiness here: apparent recursive resolution of
- * @if-enabled-then@ caused the toggle template to show status out-of-phase with
- * the actual enablement status. So a similar construct,
- * @if-enabled-display-then@, is used to resolve the status display on non-'toggle'
- * templates.
- *
- * Revision 1.36 2001/10/26 17:33:27 oes
- * marginal bugfix
- *
- * Revision 1.35 2001/10/23 21:48:19 jongfoster
- * Cleaning up error handling in CGI functions - they now send back
- * a HTML error page and should never cause a FATAL error. (Fixes one
- * potential source of "denial of service" attacks).
- *
- * CGI actions file editor that works and is actually useful.
- *
- * Ability to toggle Junkbuster remotely using a CGI call.
- *
- * You can turn off both the above features in the main configuration
- * file, e.g. if you are running a multi-user proxy.
- *
- * Revision 1.34 2001/10/18 22:22:09 david__schmidt
- * Only show "Local support" on templates conditionally:
- * - if either 'admin-address' or 'proxy-info-url' are uncommented in config
- * - if not, no Local support section appears
- *
- * Revision 1.33 2001/10/14 22:28:41 jongfoster
- * Fixing stupid typo.
- *
- * Revision 1.32 2001/10/14 22:20:18 jongfoster
- * - Changes to CGI dispatching method to match CGI names exactly,
- * rather than doing a prefix match.
- * - No longer need to count the length of the CGI handler names by hand.
- * - Adding new handler for 404 error when disptching a CGI, if none of
- * the handlers match.
- * - Adding new handlers for CGI actionsfile editor.
- *
- * Revision 1.31 2001/10/10 10:56:39 oes
- * Failiure to load template now fatal. Before, the user got a hard-to-understand assertion failure from cgi.c
- *
- * Revision 1.30 2001/10/02 15:30:57 oes
- * Introduced show-request cgi
- *
- * Revision 1.29 2001/09/20 15:47:44 steudten
- *
- * Fix BUG: Modify int size to size_t size in fill_template()
- * - removes big trouble on machines where sizeof(int) != sizeof(size_t).
- *
- * Revision 1.28 2001/09/19 18:00:37 oes
- * - Deletef time() FIXME (Can't fail under Linux either, if
- * the argument is guaranteed to be in out address space,
- * which it is.)
- * - Fixed comments
- * - Pointer notation cosmetics
- * - Fixed a minor bug in template_fill(): Failiure of
- * pcrs_execute() now secure.
- *
- * Revision 1.27 2001/09/16 17:08:54 jongfoster
- * Moving simple CGI functions from cgi.c to new file cgisimple.c
- *
- * Revision 1.26 2001/09/16 15:47:37 jongfoster
- * First version of CGI-based edit interface. This is very much a
- * work-in-progress, and you can't actually use it to edit anything
- * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
- * to have any effect.
- *
- * Revision 1.25 2001/09/16 15:02:35 jongfoster
- * Adding i.j.b/robots.txt.
- * Inlining add_stats() since it's only ever called from one place.
- *
- * Revision 1.24 2001/09/16 11:38:01 jongfoster
- * Splitting fill_template() into 2 functions:
- * template_load() loads the file
- * template_fill() performs the PCRS regexps.
- * This is because the CGI edit interface has a "table row"
- * template which is used many times in the page - this
- * change means it's only loaded from disk once.
- *
- * Revision 1.23 2001/09/16 11:16:05 jongfoster
- * Better error handling in dispatch_cgi() and parse_cgi_parameters()
- *

- * Correctly setting Last-Modified: and Expires: HTTP headers.
- *
- * Revision 1.20 2001/09/13 23:40:36 jongfoster
- * (Cosmetic only) Indentation correction
- *
- * Revision 1.19 2001/09/13 23:31:25 jongfoster
- * Moving image data to cgi.c rather than cgi.h.
- *
- * Revision 1.18 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *
- * Revision 1.17 2001/08/05 15:57:38 oes
- * Adapted finish_http_response to new list_to_text
- *
- * Revision 1.16 2001/08/01 21:33:18 jongfoster
- * Changes to fill_template() that reduce memory usage without having
- * an impact on performance. I also renamed some variables so as not
- * to clash with the C++ keywords "new" and "template".
- *
- * Revision 1.15 2001/08/01 21:19:22 jongfoster
- * Moving file version information to a separate CGI page.
- *
- * Revision 1.14 2001/08/01 00:19:03 jongfoster
- * New function: map_conditional() for an if-then-else syntax.
- * Changing to use new version of show_defines()
- *
- * Revision 1.13 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.12 2001/07/29 18:47:05 jongfoster
- * Adding missing #include "loadcfg.h"
- *
- * Revision 1.11 2001/07/18 17:24:37 oes
- * Changed to conform to new pcrs interface
- *
- * Revision 1.10 2001/07/13 13:53:13 oes
- * Removed all #ifdef PCRS and related code
- *
- * Revision 1.9 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.8 2001/06/29 13:21:46 oes
- * - Cosmetics: renamed and reordered functions, variables,
- * texts, improved comments etc
- *
- * - Removed ij_untrusted_url() The relevant
- * info is now part of the "untrusted" page,
- * which is generated by filters.c:trust_url()
- *
- * - Generators of content now call finish_http_response()
- * themselves, making jcc.c:chat() a little less
- * cluttered
- *
- * - Removed obsolete "Pragma: no-cache" from our headers
- *
- * - http_responses now know their head length
- *
- * - fill_template now uses the new interface to pcrs, so that
- * - long jobs (like whole files) no longer have to be assembled
- * in a fixed size buffer
- * - the new T (trivial) option is used, and the replacement may
- * contain Perl syntax backrefs without confusing pcrs
- *
- * - Introduced default_exports() which generates a set of exports
- * common to all CGIs and other content generators
- *
- * - Introduced convenience function map_block_killer()
- *
- * - Introduced convenience function make_menu()
- *
- * - Introduced CGI-like function error_response() which generates
- * the "No such domain" and "Connect failed" messages using the
- * CGI platform
- *
- * - cgi_show_url_info:
- * - adapted to new CGI features
- * - form and answers now generated from same template
- * - http:// prefix in URL now OK
- *
- * - cgi_show_status:
- * - adapted to new CGI features
- * - no longer uses csp->init_proxy_args

- * - Changed built-in images from GIF to PNG
- * (with regard to Unisys patent issue)
- * - Added a 4x4 pattern PNG which is less intrusive
- * than the logo but also clearly marks the deleted banners
- *
- * Revision 1.20 2002/03/04 17:53:22 oes
- * Fixed compiled warning
- *
- * Revision 1.19 2002/01/21 00:33:52 jongfoster
- * Adding map_block_keep() to save a few bytes in the edit-actions-list HTML.
- *
- * Revision 1.18 2001/11/16 00:46:31 jongfoster
- * Fixing compiler warnings
- *
- * Revision 1.17 2001/10/23 21:48:19 jongfoster
- * Cleaning up error handling in CGI functions - they now send back
- * a HTML error page and should never cause a FATAL error. (Fixes one
- * potential source of "denial of service" attacks).
- *
- * CGI actions file editor that works and is actually useful.
- *
- * Ability to toggle Junkbuster remotely using a CGI call.
- *
- * You can turn off both the above features in the main configuration
- * file, e.g. if you are running a multi-user proxy.
- *
- * Revision 1.16 2001/09/16 17:08:54 jongfoster
- * Moving simple CGI functions from cgi.c to new file cgisimple.c
- *
- * Revision 1.15 2001/09/16 15:02:35 jongfoster
- * Adding i.j.b/robots.txt.
- * Inlining add_stats() since it's only ever called from one place.
- *
- * Revision 1.14 2001/09/16 11:38:02 jongfoster
- * Splitting fill_template() into 2 functions:
- * template_load() loads the file
- * template_fill() performs the PCRS regexps.
- * This is because the CGI edit interface has a "table row"
- * template which is used many times in the page - this
- * change means it's only loaded from disk once.
- *
- * Revision 1.13 2001/09/16 11:00:10 jongfoster
- * New function alloc_http_response, for symmetry with free_http_response

- *
- * Revision 1.11 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *
- * Revision 1.10 2001/08/01 21:19:22 jongfoster
- * Moving file version information to a separate CGI page.
- *
- * Revision 1.9 2001/08/01 00:17:54 jongfoster
- * Adding prototype for map_conditional

- * ANSI C rules.
- *
- * Revision 1.6 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.5 2001/06/29 13:22:44 oes
- * - Cleaned up
- * - Added new functions: default_exports(), make_menu(),
- * error_response() etc, ranamed others and changed
- * param and return types.
- * - Removed HTTP/HTML snipplets
- * - Removed logentry from cancelled commit
- *
- * Revision 1.4 2001/06/09 10:50:58 jongfoster

- * introduced new cgi handling
- *
- * No revisions before 1.3

- * Revision 1.31 2002/04/18 19:21:08 jongfoster
- * Added code to detect "conventional" action files, that start

- *
- * Revision 1.12 2002/03/03 09:18:03 joergs
- * Made jumbjuster work on AmigaOS again.
- *
- * Revision 1.11 2002/01/23 01:03:31 jongfoster
- * Fixing gcc [CygWin] compiler warnings
- *
- * Revision 1.10 2002/01/23 00:22:59 jongfoster
- * Adding new function cgi_edit_actions_section_swap(), to reorder
- * the actions file.
- *
- * Adding get_url_spec_param() to get a validated URL pattern.
- *
- * Moving edit_read_line() out of this file and into loaders.c.
- *
- * Adding missing html_encode() to many CGI functions.
- *
- * Moving the functions that #include actionlist.h to the end of the file,
- * because the Visual C++ 97 debugger gets extremely confused if you try
- * to debug any code that comes after them in the file.
- *
- * Major optimizations in cgi_edit_actions_list() to reduce the size of
- * the generated HTML (down 40% from 550k to 304k), with major side-effects
- * throughout the editor and templates. In particular, the length of the
- * URLs throughout the editor has been drastically reduced, by cutting
- * paramater names down to 1 character and CGI names down to 3-4
- * characters, by removing all non-essential CGI paramaters even at the
- * expense of having to re-read the actions file for the most trivial
- * page, and by using relative rather than absolute URLs. This means
- * that this (typical example):
- *
- * <a href="http://ijbswa.sourceforge.net/config/edit-actions-url-form?
- * filename=ijb&ver=1011487572&section=12&pattern=13
- * &oldval=www.oesterhelt.org%2Fdeanimate-demo">
- *
- * is now this:
- *
- * <a href="eau?f=ijb&v=1011487572&p=13">
- *
- * Revision 1.9 2002/01/17 20:56:22 jongfoster
- * Replacing hard references to the URL of the config interface
- * with #defines from project.h
- *
- * Revision 1.8 2001/11/30 23:35:51 jongfoster
- * Renaming actionsfile to ijb.action
- *
- * Revision 1.7 2001/11/13 00:28:24 jongfoster
- * - Renaming parameters from edit-actions-for-url so that they only
- * contain legal JavaScript characters. If we wanted to write
- * JavaScript that worked with Netscape 4, this is nessacery.
- * (Note that at the moment the JavaScript doesn't actually work
- * with Netscape 4, but now this is purely a template issue, not
- * one affecting code).
- * - Adding new CGIs for use by non-JavaScript browsers:
- * edit-actions-url-form
- * edit-actions-add-url-form
- * edit-actions-remove-url-form
- * - Fixing || bug.
- *
- * Revision 1.6 2001/10/29 03:48:09 david__schmidt
- * OS/2 native needed a snprintf() routine. Added one to miscutil, brackedted
- * by and __OS2__ ifdef.
- *
- * Revision 1.5 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.4 2001/10/23 21:48:19 jongfoster
- * Cleaning up error handling in CGI functions - they now send back
- * a HTML error page and should never cause a FATAL error. (Fixes one
- * potential source of "denial of service" attacks).
- *
- * CGI actions file editor that works and is actually useful.
- *
- * Ability to toggle JunkBuster remotely using a CGI call.
- *
- * You can turn off both the above features in the main configuration
- * file, e.g. if you are running a multi-user proxy.
- *
- * Revision 1.3 2001/10/14 22:12:49 jongfoster
- * New version of CGI-based actionsfile editor.
- * Major changes, including:
- * - Completely new file parser and file output routines
- * - edit-actions CGI renamed edit-actions-for-url
- * - All CGIs now need a filename parameter, except for...
- * - New CGI edit-actions which doesn't need a filename,
- * to allow you to start the editor up.
- * - edit-actions-submit now works, and now automatically
- * redirects you back to the main edit-actions-list handler.
- *
- * Revision 1.2 2001/09/16 17:05:14 jongfoster
- * Removing unused #include showarg.h
- *
- * Revision 1.1 2001/09/16 15:47:37 jongfoster
- * First version of CGI-based edit interface. This is very much a
- * work-in-progress, and you can't actually use it to edit anything
- * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
- * to have any effect.

- * a HTML error page and should never cause a FATAL error. (Fixes one
- * potential source of "denial of service" attacks).
- *
- * CGI actions file editor that works and is actually useful.
- *
- * Ability to toggle JunkBuster remotely using a CGI call.
- *
- * You can turn off both the above features in the main configuration
- * file, e.g. if you are running a multi-user proxy.
- *
- * Revision 1.2 2001/10/14 22:12:49 jongfoster
- * New version of CGI-based actionsfile editor.
- * Major changes, including:
- * - Completely new file parser and file output routines
- * - edit-actions CGI renamed edit-actions-for-url
- * - All CGIs now need a filename parameter, except for...
- * - New CGI edit-actions which doesn't need a filename,
- * to allow you to start the editor up.
- * - edit-actions-submit now works, and now automatically
- * redirects you back to the main edit-actions-list handler.
- *
- * Revision 1.1 2001/09/16 15:47:37 jongfoster
- * First version of CGI-based edit interface. This is very much a
- * work-in-progress, and you can't actually use it to edit anything
- * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
- * to have any effect.

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

- *
- * Revision 1.40 2006/09/09 13:05:33 fabiankeil

- * Deliver documents in the user-manual directory

- * Revision 1.8 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand

- * memory that was used.

- * 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 22:00:32 jongfoster
- * Adding support for a 404 error when an invalid CGI page is requested.
- *
- * Revision 1.2 2001/10/02 15:31:20 oes
- * Introduced show-request cgi
- *

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

- * Update error logging to give sane values for thread IDs on Mach kernels.

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

- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *

- * Now prints thread ID for each message (pthreads only)
- *
- * Revision 1.14 2001/07/19 19:03:48 haroon
- * - Added case for LOG_LEVEL_POPUPS
- *
- * Revision 1.13 2001/07/13 13:58:58 oes
- * - Added case for LOG_LEVEL_DEANIMATE
- * - Removed all #ifdef PCRS

- *
- * Revision 1.11 2001/06/01 18:14:49 jongfoster
- * Changing the calls to strerr() to check HAVE_STRERR (which is defined
- * in config.h if appropriate) rather than the NO_STRERR macro.
- *

- *
- * Revision 1.6 2001/05/25 21:55:08 jongfoster
- * Now cleans up properly on FATAL (removes taskbar icon etc)
- *
- * Revision 1.5 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.4 2001/05/21 19:32:54 jongfoster
- * Added another #ifdef _WIN_CONSOLE
- *
- * Revision 1.3 2001/05/20 01:11:40 jongfoster
- * Added support for LOG_LEVEL_FATAL
- * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
- * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
- *
- * Revision 1.2 2001/05/17 22:42:01 oes
- * - Cleaned CRLF's from the sources and related files
- * - Repaired logging for REF and FRC
- *
- * Revision 1.1.1.1 2001/05/15 13:58:51 oes
- * Initial import of version 2.9.3 source tree

- * Revision 1.95 2007/10/17 19:31:20 fabiankeil
- * Omitting the zero chunk that ends the chunk transfer encoding seems
- * to be the new black. Log the problem and continue filtering anyway.
- *
- * Revision 1.94 2007/09/29 13:20:20 fabiankeil
- * Remove two redundant and one useless log messages.
- *
- * Revision 1.93 2007/09/29 10:21:16 fabiankeil

- * Revision 1.92 2007/09/28 16:38:55 fabiankeil
- * - Execute content filters through execute_content_filter().
- * - Add prepare_for_filtering() so filter functions don't have to
- * care about de-chunking and decompression. As a side effect this enables
- * decompression for gif_deanimate_response() and jpeg_inspect_response().
- * - Change remove_chunked_transfer_coding()'s return type to jb_err.

- *
- * Revision 1.88 2007/06/01 16:41:11 fabiankeil
- * Add forward-override{} to change the forwarding settings through
- * action sections. This is mainly interesting to forward different
- * clients differently (for example based on User-Agent or request
- * origin).
- *
- * Revision 1.87 2007/04/30 15:53:10 fabiankeil
- * Make sure filters with dynamic jobs actually use them.
- *
- * Revision 1.86 2007/04/30 15:03:28 fabiankeil
- * - Introduce dynamic pcrs jobs that can resolve variables.

- * unless they are activated more than once.

- * Revision 1.85 2007/03/21 12:24:47 fabiankeil
- * - Log the content size after decompression in decompress_iob()
- * instead of pcrs_filter_response().
- *
- * Revision 1.84 2007/03/20 15:16:34 fabiankeil
- * Use dedicated header filter actions instead of abusing "filter".
- * Replace "filter-client-headers" and "filter-client-headers"
- * with "server-header-filter" and "client-header-filter".

- * Revision 1.83 2007/03/17 15:20:05 fabiankeil
- * New config option: enforce-blocks.

- * Revision 1.44 2002/03/07 03:49:31 oes
- * - Fixed compiler warnings etc
- * - Changed built-in images from GIF to PNG
- * (with regard to Unisys patent issue)
- * - Added a 4x4 pattern PNG which is less intrusive
- * than the logo but also clearly marks the deleted banners
- *
- * Revision 1.43 2002/01/22 23:51:59 jongfoster
- * Replacing strsav() with the safer string_append().
- *
- * Adding missing html_encode() to error message generators. Where encoded
- * and unencoded versions of a string were provided, removing the unencoded
- * one.
- *
- * Revision 1.42 2002/01/17 21:00:32 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Using a single, simple url_match(pattern,url) function - rather than
- * the 3-line match routine which was repeated all over the place.
- *
- * Renaming free_url to free_url_spec, since it frees a struct url_spec.
- *
- * Using parse_http_url() to parse URLs without faking a HTTP
- * request line for parse_http_request().
- *
- * Revision 1.41 2001/11/13 00:14:07 jongfoster
- * Fixing stupid bug now I've figured out what || means.
- * (It always returns 0 or 1, not one of it's paramaters.)
- *
- * Revision 1.40 2001/10/26 17:37:55 oes
- * - Re-enabled Netscape 200/404 bug workaround in block_url():
- * - Removed OS/2 special case
- * - Made block_url() independant from sed() having been run
- * - Made trust_url independant from sed() having been run
- * - Made is_imageurl independant from sed() having been run.
- * It now checks User-Agent: and Accept: by itself.
- *
- *
- * Revision 1.39 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.38 2001/10/23 21:32:33 jongfoster
- * Adding error-checking to selected functions
- *
- * Revision 1.37 2001/10/22 15:33:56 david__schmidt
- * Special-cased OS/2 out of the Netscape-abort-on-404-in-js problem in
- * filters.c. Added a FIXME in front of the offending code. I'll gladly
- * put in a better/more robust fix for all parties if one is presented...
- * It seems that just returning 200 instead of 404 would pretty much fix
- * it for everyone, but I don't know all the history of the problem.
- *
- * Revision 1.36 2001/10/10 16:44:16 oes
- * Added match_portlist function
- *
- * Revision 1.35 2001/10/07 15:41:23 oes
- * Replaced 6 boolean members of csp with one bitmap (csp->flags)
- *
- * New function remove_chunked_transfer_coding that strips chunked
- * transfer coding to plain and is called by pcrs_filter_response
- * and gif_deanimate_response if neccessary
- *
- * Improved handling of zero-change re_filter runs
- *
- * pcrs_filter_response and gif_deanimate_response now remove
- * chunked transfer codeing before processing the body.
- *
- * Revision 1.34 2001/09/20 15:49:36 steudten
- *
- * Fix BUG: Change int size to size_t size in pcrs_filter_response().
- * See cgi.c fill_template().
- *
- * Revision 1.33 2001/09/16 17:05:14 jongfoster
- * Removing unused #include showarg.h
- *
- * Revision 1.32 2001/09/16 13:21:27 jongfoster
- * Changes to use new list functions.
- *
- * Revision 1.31 2001/09/16 11:38:02 jongfoster
- * Splitting fill_template() into 2 functions:
- * template_load() loads the file
- * template_fill() performs the PCRS regexps.
- * This is because the CGI edit interface has a "table row"
- * template which is used many times in the page - this
- * change means it's only loaded from disk once.
- *
- * Revision 1.30 2001/09/16 11:00:10 jongfoster
- * New function alloc_http_response, for symmetry with free_http_response
- *
- * Revision 1.29 2001/09/13 23:32:40 jongfoster
- * Moving image data to cgi.c rather than cgi.h
- * Fixing a GPF under Win32 (and any other OS that protects global
- * constants from being written to).
- *
- * Revision 1.28 2001/09/10 10:18:51 oes
- * Silenced compiler warnings
- *
- * Revision 1.27 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *
- * Revision 1.26 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.25 2001/07/26 10:09:46 oes
- * Made browser detection a little less naive
- *
- * Revision 1.24 2001/07/25 17:22:51 oes
- * Added workaround for Netscape bug that prevents display of page when loading a component fails.
- *
- * Revision 1.23 2001/07/23 13:40:12 oes
- * Fixed bug that caused document body to be dropped when pcrs joblist was empty.
- *
- * Revision 1.22 2001/07/18 12:29:34 oes
- * - Made gif_deanimate_response respect
- * csp->action->string[ACTION_STRING_DEANIMATE]
- * - Logging cosmetics
- *
- * Revision 1.21 2001/07/13 13:59:53 oes
- * - Introduced gif_deanimate_response which shares the
- * generic content modification interface of pcrs_filter_response
- * and acts as a wrapper to deanimate.c:gif_deanimate()
- * - Renamed re_process_buffer to pcrs_filter_response
- * - pcrs_filter_response now returns NULL on failiure
- * - Removed all #ifdef PCRS
- *
- * Revision 1.20 2001/07/01 17:01:04 oes
- * Added comments and missing return statement in is_untrusted_url()
- *
- * Revision 1.19 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.18 2001/06/29 13:27:38 oes
- * - Cleaned up, renamed and reorderd functions
- * and improved comments
- *
- * - block_url:
- * - Ported to CGI platform. Now delivers
- * http_response or NULL
- * - Unified HTML and GIF generation (moved image detection
- * and GIF generation here from jcc.c:chat())
- * - Fixed HTTP status to:
- * - 403 (Forbidden) for the "blocked" HTML message
- * - 200 (OK) for GIF answers
- * - 302 (Redirect) for redirect to GIF
- *
- * - trust_url:
- * - Ported to CGI platform. Now delivers
- * http_response or NULL
- * - Separated detection of untrusted URL into
- * (bool)is_untrusted_url
- * - Added enforcement of untrusted requests
- *
- * - Moved redirect_url() from cgi.c to here
- * and ported it to the CGI platform
- *
- * - Removed logentry from cancelled commit
- *
- * Revision 1.17 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.16 2001/06/07 23:10:26 jongfoster
- * Allowing unanchored domain patterns to back off and retry
- * if they partially match. Optimized right-anchored patterns.
- * Moving ACL and forward files into config file.
- * Replacing struct gateway with struct forward_spec
- *
- * Revision 1.15 2001/06/03 19:12:00 oes
- * extracted-CGI relevant stuff
- *
- * Revision 1.14 2001/06/01 10:30:55 oes
- * Added optional left-anchoring to domaincmp
- *
- * Revision 1.13 2001/05/31 21:21:30 jongfoster
- * Permissionsfile / actions file changes:
- * - Changed "permission" to "action" throughout
- * - changes to file format to allow string parameters
- * - Moved helper functions to actions.c
- *
- * Revision 1.12 2001/05/31 17:35:20 oes
- *
- * - Enhanced domain part globbing with infix and prefix asterisk
- * matching and optional unanchored operation
- *
- * Revision 1.11 2001/05/29 11:53:23 oes
- * "See why" link added to "blocked" page
- *
- * Revision 1.10 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.9 2001/05/27 22:17:04 oes
- *
- * - re_process_buffer no longer writes the modified buffer
- * to the client, which was very ugly. It now returns the
- * buffer, which it is then written by chat.
- *
- * - content_length now adjusts the Content-Length: header
- * for modified documents rather than crunch()ing it.
- * (Length info in csp->content_length, which is 0 for
- * unmodified documents)
- *
- * - For this to work, sed() is called twice when filtering.
- *
- * Revision 1.8 2001/05/26 17:13:28 jongfoster
- * Filled in a function comment.
- *
- * Revision 1.7 2001/05/26 15:26:15 jongfoster
- * ACL feature now provides more security by immediately dropping
- * connections from untrusted hosts.
- *
- * Revision 1.6 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.5 2001/05/25 22:34:30 jongfoster
- * Hard tabs->Spaces
- *
- * Revision 1.4 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.3 2001/05/20 16:44:47 jongfoster
- * Removing last hardcoded Junkbusters.com URLs.
- *
- * Revision 1.2 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.1.1.1 2001/05/15 13:58:52 oes
- * Initial import of version 2.9.3 source tree

- * Revision 1.32 2008/02/23 16:33:43 fabiankeil
- * Let forward_url() use the standard parameter ordering
- * and mark its second parameter immutable.
- *
- * Revision 1.31 2007/10/19 16:53:28 fabiankeil
- * Add helper function to check if any content filters are enabled.
- *
- * Revision 1.30 2007/09/29 10:21:16 fabiankeil
- * - Move get_filter_function() from jcc.c to filters.c
- * so the filter functions can be static.
- * - Don't bother filtering body-less responses.
- *
- * Revision 1.29 2007/09/28 16:38:55 fabiankeil
- * - Execute content filters through execute_content_filter().
- * - Add prepare_for_filtering() so filter functions don't have to
- * care about de-chunking and decompression. As a side effect this enables
- * decompression for gif_deanimate_response() and jpeg_inspect_response().
- * - Change remove_chunked_transfer_coding()'s return type to jb_err.
- * Some clowns feel like chunking empty responses in which case
- * (size == 0) is valid but previously would be interpreted as error.
- *
- * Revision 1.28 2007/09/02 15:31:20 fabiankeil
- * Move match_portlist() from filter.c to urlmatch.c.
- * It's used for url matching, not for filtering.

- * Introduce dynamic pcrs jobs that can resolve variables.
- *
- * Revision 1.26 2007/03/13 11:28:43 fabiankeil
- * - Fix port handling in acl_addr() and use a temporary acl spec
- * copy so error messages don't contain a truncated version.
- * - Log size of iob before and after decompression.
- *
- * Revision 1.25 2007/01/12 15:36:44 fabiankeil
- * Mark *csp as immutable for is_untrusted_url()
- * and is_imageurl(). Closes FR 1237736.
- *
- * Revision 1.24 2006/12/29 18:30:46 fabiankeil
- * Fixed gcc43 conversion warnings,
- * changed sprintf calls to snprintf.

- * Implemented +redirect{s@foo@bar@} to generate
- * a redirect based on a rewritten version of the
- * original URL.
- *
- * Revision 1.22 2006/07/18 14:48:46 david__schmidt
- * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
- * with what was really the latest development (the v_3_0_branch branch)
- *
- * Revision 1.20.2.2 2004/10/03 12:53:32 david__schmidt
- * Add the ability to check jpeg images for invalid
- * lengths of comment blocks. Defensive strategy
- * against the exploit:
- * Microsoft Security Bulletin MS04-028
- * Buffer Overrun in JPEG Processing (GDI+) Could
- * Allow Code Execution (833987)
- * Enabled with +inspect-jpegs in actions files.
- *
- * Revision 1.20.2.1 2002/09/25 14:51:51 oes
- * Added basic support for OPTIONS and TRACE HTTP methods:
- * New function direct_response which handles OPTIONS and
- * TRACE requests whose Max-Forwards header field is zero.
- *
- * Revision 1.20 2002/04/02 14:56:16 oes
- * Bugfix: is_untrusted_url() and trust_url() now depend on FEATURE_TRUST, not FEATURE_COOKIE_JAR
- *
- * Revision 1.19 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.18 2002/03/25 22:12:45 oes

- *
- * Revision 1.17 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.16 2002/01/17 21:01:02 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Revision 1.15 2001/10/10 16:44:16 oes
- * Added match_portlist function
- *
- * Revision 1.14 2001/10/07 15:41:40 oes
- * Added prototype for remove_chunked_transfer_coding
- *
- * Revision 1.13 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.12 2001/07/29 19:01:11 jongfoster
- * Changed _FILENAME_H to FILENAME_H_INCLUDED.
- * Added forward declarations for needed structures.
- *
- * Revision 1.11 2001/07/13 14:00:18 oes
- * - Introduced gif_deanimate_response
- * - Renamed re_process_buffer to pcrs_filter_response
- * - Removed all #ifdef PCRS
- *
- * Revision 1.10 2001/06/29 13:29:01 oes
- * Cleaned up and updated to reflect the changesin
- * filters.c
- *
- * Revision 1.9 2001/06/07 23:10:53 jongfoster

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

- *
- * Revision 1.39 2008/10/25 11:33:01 fabiankeil
- * Remove already out-commented line left over from debugging.
- *
- * Revision 1.38 2008/10/24 17:33:00 fabiankeil
- * - Tone the "keep-alive support is experimental" warning
- * down a bit as hackish 0-chunk detection has been
- * implemented recently.
- * - Only show the "ndef HAVE_POLL" warning once on start-up.
- *
- * Revision 1.37 2008/10/23 17:40:53 fabiankeil
- * Fix forget_connection() and mark_connection_unused(),
- * which would both under certain circumstances access
- * reusable_connection[MAX_REUSABLE_CONNECTIONS]. Oops.
- *
- * Revision 1.36 2008/10/18 19:49:15 fabiankeil
- * - Factor close_unusable_connections() out of
- * get_reusable_connection() to make sure we really check
- * all the remembered connections, not just the ones before
- * the next reusable one.
- * - Plug two file descriptor leaks. Internally marking
- * connections as closed doesn't cut it.
- *
- * Revision 1.35 2008/10/17 17:12:01 fabiankeil
- * In socket_is_still_usable(), use select()
- * and FD_ISSET() if poll() isn't available.

- * - Factor socket_is_still_usable() out of get_reusable_connection().
- * - If poll() isn't available, show a warning and assume the socket
- * is still usable.
- *
- * Revision 1.30 2008/10/13 17:31:03 fabiankeil
- * If a remembered connection is no longer usable and
- * has been marked closed, don't bother checking if the
- * destination matches.
- *
- * Revision 1.29 2008/10/11 16:59:41 fabiankeil
- * Add missing dots for two log messages.
- *
- * Revision 1.28 2008/10/09 18:21:41 fabiankeil

- * Revision 1.27 2008/09/27 15:05:51 fabiankeil
- * Return only once in forwarded_connect().
- *

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

- * Revision 1.23 2008/02/04 13:11:35 fabiankeil
- * Remember the cause of the SOCKS5 error for the CGI message.
- *
- * Revision 1.22 2008/02/03 13:46:15 fabiankeil
- * Add SOCKS5 support. Patch #1862863 by Eric M. Hopper with minor changes.
- *
- * Revision 1.21 2007/07/28 12:30:03 fabiankeil

- * fix socks requests on big-endian platforms.
- *
- * Revision 1.20 2007/05/14 10:23:48 fabiankeil
- * - Use strlcpy() instead of strcpy().
- * - Use the same buffer for socks requests and socks responses.
- * - Fix bogus warning about web_server_addr being used uninitialized.
- *
- * Revision 1.19 2007/01/25 14:09:45 fabiankeil
- * - Save errors in socks4_connect() to csp->error_message.

- * Killing warnings
- *
- * Revision 1.12 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.11 2002/03/08 17:46:04 jongfoster
- * Fixing int/size_t warnings
- *
- * Revision 1.10 2002/03/07 03:50:19 oes
- * - Improved handling of failed DNS lookups
- * - Fixed compiler warnings
- *
- * Revision 1.9 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.8 2001/09/13 20:10:12 jongfoster
- * Fixing missing #include under Windows
- *
- * Revision 1.7 2001/09/12 17:58:26 steudten
- *
- * add #include <string.h>
- *
- * Revision 1.6 2001/09/10 10:41:16 oes
- * Added #include in.h
- *
- * Revision 1.5 2001/07/29 18:47:57 jongfoster
- * Adding missing #include project.h
- *
- * Revision 1.4 2001/07/24 12:47:06 oes

- * Revision 1.3 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.2 2001/06/07 23:11:38 jongfoster
- * Removing gateways[] list - no longer used.
- * Replacing function pointer in struct gateway with a directly
- * called function forwarded_connect(), which can do the common
- * task of deciding whether to connect to the web server or HTTP
- * proxy.
- * Replacing struct gateway with struct forward_spec
- * Fixing bug with SOCKS4A and HTTP proxy server in combination.
- * It was a bug which led to the connection being made to the web
- * server rather than the HTTP proxy, and also a buffer overrun.
- *
- * Revision 1.1.1.1 2001/05/15 13:58:54 oes
- * Initial import of version 2.9.3 source tree

- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.3 2001/07/29 18:58:15 jongfoster
- * Removing nested #includes, adding forward declarations for needed
- * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
- *
- * Revision 1.2 2001/06/07 23:12:14 jongfoster
- * Removing gateways[] list - no longer used.
- * Replacing function pointer in struct gateway with a directly

- * Replacing struct gateway with struct forward_spec

- *
- * Revision 1.53 2009/04/17 11:39:52 fabiankeil

- *
- * Revision 1.50 2008/12/20 14:53:55 fabiankeil
- * Add config option socket-timeout to control the time
- * Privoxy waits for data to arrive on a socket. Useful
- * in case of stale ssh tunnels or when fuzz-testing.
- *
- * Revision 1.49 2008/11/10 17:03:57 fabiankeil
- * Fix a gcc44 warning and remove a now-obsolete cast.
- *
- * Revision 1.48 2008/09/04 08:13:58 fabiankeil
- * Prepare for critical sections on Windows by adding a
- * layer of indirection before the pthread mutex functions.
- *
- * Revision 1.47 2008/03/26 18:07:07 fabiankeil
- * Add hostname directive. Closes PR#1918189.
- *
- * Revision 1.46 2008/03/21 11:13:57 fabiankeil
- * Only gather host information if it's actually needed.
- * Also move the code out of accept_connection() so it's less likely
- * to delay other incoming connections if the host is misconfigured.
- *
- * Revision 1.45 2007/09/30 16:59:22 fabiankeil
- * Set the maximum listen() backlog to 128. Apparently SOMAXCONN is
- * neither high enough, nor a hard limit on mingw32. Again for BR#1795281.
- *
- * Revision 1.44 2007/09/15 13:01:31 fabiankeil
- * Increase listen() backlog to SOMAXCONN (or 128) to decrease
- * chances of dropped connections under load. Problem reported
- * and fix suggested by nobody in BR#1795281.
- *
- * Revision 1.43 2007/06/01 18:16:36 fabiankeil
- * Use the same mutex for gethostbyname() and gethostbyaddr() to prevent
- * deadlocks and crashes on OpenBSD and possibly other OS with neither
- * gethostbyname_r() nor gethostaddr_r(). Closes BR#1729174.
- * Thanks to Ralf Horstmann for report and solution.
- *
- * Revision 1.42 2007/04/01 17:37:07 fabiankeil
- * - Add DNS retries for Solaris and other systems
- * whose gethostbyname_r version takes five arguments.
- * - Move maximum number of DNS retries into a macro.
- *
- * Revision 1.41 2006/11/13 19:05:51 fabiankeil
- * Make pthread mutex locking more generic. Instead of
- * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
- * and use mutex locking unless there is an _r function
- * available. Better safe than sorry.
- *
- * Fixes "./configure --disable-pthread" and should result
- * in less threading-related problems on pthread-using platforms,
- * but it still doesn't fix BR#1122404.
- *
- * Revision 1.40 2006/09/02 15:36:42 fabiankeil
- * Follow the OpenBSD port's lead and protect the resolve
- * functions on OpenBSD as well.
- *
- * Revision 1.39 2006/08/03 02:46:41 david__schmidt

- * Don't rely on h_addr being non-NULL after gethostbyname.
- * Works around an oddness in Max OSX and closes bug #724796
- *
- * Revision 1.35.2.4 2003/04/04 12:40:20 oes
- * Made sure the errno set by bind, not close[socket] is used in
- * bind_port. Probably fixes bugs #713777, #705562.
- *
- * Revision 1.35.2.3 2003/03/07 03:41:04 david__schmidt
- * Wrapping all *_r functions (the non-_r versions of them) with mutex semaphores for OSX. Hopefully this will take care of all of those pesky crash reports.
- *
- * Revision 1.35.2.2 2002/11/20 14:37:24 oes

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

- *
- * Revision 1.20 2001/11/16 00:48:48 jongfoster
- * Enabling duplicate-socket detection for all platforms, not
- * just Win32.
- *
- * Revision 1.19 2001/10/25 03:40:47 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.18 2001/09/21 23:02:02 david__schmidt
- * Cleaning up 2 compiler warnings on OS/2.
- *
- * Revision 1.17 2001/09/13 20:11:46 jongfoster

- * Call initialize_mutexes() before init_log_module() again.
- * Broken since r220, might be the cause of Lee's #2579448.
- *
- * Revision 1.221 2009/02/06 18:02:58 fabiankeil
- * When dropping privileges, also give up membership in supplementary
- * groups. Thanks to Matthias Drochner for reporting the problem,
- * providing the initial patch and testing the final version.
- *
- * Revision 1.220 2009/02/04 18:29:07 fabiankeil
- * Initialize the log module before parsing arguments.
- * Thanks to Matthias Drochner for the report.
- *
- * Revision 1.219 2009/01/31 16:08:21 fabiankeil
- * Remove redundant error check in receive_client_request().
- *
- * Revision 1.218 2009/01/31 12:25:54 fabiankeil
- * Flatten indentation in receive_client_request().
- *
- * Revision 1.217 2009/01/07 19:50:09 fabiankeil
- * - If the socket-timeout has been reached and the client
- * hasn't received any data yet, send an explanation before
- * closing the connection.
- * - In get_request_line(), signal timeouts the right way.
- *
- * Revision 1.216 2008/12/24 22:13:11 ler762
- * fix GCC 3.4.4 warning
- *
- * Revision 1.215 2008/12/24 17:06:19 fabiankeil
- * Keep a thread around to timeout alive connections
- * even if no new requests are coming in.
- *
- * Revision 1.214 2008/12/20 14:53:55 fabiankeil
- * Add config option socket-timeout to control the time
- * Privoxy waits for data to arrive on a socket. Useful
- * in case of stale ssh tunnels or when fuzz-testing.
- *
- * Revision 1.213 2008/12/15 18:45:51 fabiankeil
- * When logging crunches, log the whole URL, so one can easily
- * differentiate between vanilla HTTP and CONNECT requests.
- *
- * Revision 1.212 2008/12/14 15:46:22 fabiankeil
- * Give crunched requests their own log level.
- *
- * Revision 1.211 2008/12/06 10:05:03 fabiankeil
- * Downgrade "Received x bytes while expecting y." message to
- * LOG_LEVEL_CONNECT as it doesn't necessarily indicate an error.
- *
- * Revision 1.210 2008/12/02 22:03:18 fabiankeil
- * Don't miscalculate byte_count if we don't get all the
- * server headers with one read_socket() call. With keep-alive
- * support enabled, this caused delays until the server closed
- * the connection.
- *
- * Revision 1.209 2008/11/27 09:44:04 fabiankeil
- * Cosmetics for the last commit: Don't watch out for
- * the last chunk if the content isn't chunk-encoded or
- * if we already determined the content length previously.
- *
- * Revision 1.208 2008/11/26 18:24:17 fabiankeil
- * Recognize that the server response is complete if the
- * last chunk is read together with the server headers.
- * Reported by Lee.
- *
- * Revision 1.207 2008/11/25 17:25:16 fabiankeil
- * Don't convert the client-header list to text until we need to.
- *
- * Revision 1.206 2008/11/23 17:00:11 fabiankeil
- * Some more chat() cosmetics.
- *
- * Revision 1.205 2008/11/16 12:43:49 fabiankeil
- * Turn keep-alive support into a runtime feature
- * that is disabled by setting keep-alive-timeout
- * to a negative value.
- *
- * Revision 1.204 2008/11/06 19:42:17 fabiankeil
- * Fix last-chunk detection hack to also apply
- * if buf[] contains nothing but the last-chunk.
- *
- * Revision 1.203 2008/11/06 18:34:35 fabiankeil
- * Factor receive_client_request() and
- * parse_client_request() out of chat().
- *
- * Revision 1.202 2008/11/02 18:40:34 fabiankeil
- * If we received a different amount of data than we expected,
- * log a warning and make sure the server socket isn't reused.
- *
- * Revision 1.201 2008/11/02 16:48:20 fabiankeil
- * Revert revision 1.195 and try again.
- *
- * Revision 1.200 2008/10/26 16:53:18 fabiankeil
- * Fix gcc44 warning.
- *
- * Revision 1.199 2008/10/26 15:36:10 fabiankeil
- * Remove two debug messages with LOG_LEVEL_INFO.
- *
- * Revision 1.198 2008/10/22 15:19:55 fabiankeil
- * Once More, With Feeling: if there is no logfile
- * because the user didn't specify one, we shouldn't
- * call init_error_log() after receiving SIGHUP either.
- *
- * Revision 1.197 2008/10/20 17:02:40 fabiankeil
- * If SIGHUP is received while we aren't running in daemon
- * mode, calling init_error_log() would be a mistake.
- *
- * Revision 1.196 2008/10/16 09:16:41 fabiankeil
- * - Fix two gcc44 conversion warnings.
- * - Don't bother logging the last five bytes
- * of the 0-chunk.
- *
- * Revision 1.195 2008/10/13 16:04:37 fabiankeil
- * Make sure we don't try to reuse tainted server sockets.
- *
- * Revision 1.194 2008/10/12 18:35:18 fabiankeil
- * The last commit was a bit too ambitious, apparently the content
- * length adjustment is only necessary if we aren't buffering.
- *
- * Revision 1.193 2008/10/12 15:57:35 fabiankeil
- * Fix content length calculation if we read headers
- * and the start of the body at once. Now that we have
- * FEATURE_CONNECTION_KEEP_ALIVE, it actually matters.
- *
- * Revision 1.192 2008/10/11 18:19:14 fabiankeil
- * Even more chat() cosmetics.
- *
- * Revision 1.191 2008/10/11 18:00:14 fabiankeil
- * Reformat some comments in chat().
- *
- * Revision 1.190 2008/10/11 14:58:00 fabiankeil
- * In case of chunk-encoded content, stop reading if
- * the buffer looks like it ends with the last chunk.
- *
- * Revision 1.189 2008/10/11 09:53:00 fabiankeil
- * Let server_response_is_complete() deal properly with
- * content that is neither buffered nor read all at once.
- *
- * Revision 1.188 2008/10/09 18:21:41 fabiankeil
- * Flush work-in-progress changes to keep outgoing connections
- * alive where possible. Incomplete and mostly #ifdef'd out.
- *
- * Revision 1.187 2008/09/07 12:35:05 fabiankeil
- * Add mutex lock support for _WIN32.
- *

- * layer of indirection before the pthread mutex functions.
- *
- * Revision 1.185 2008/08/30 12:03:07 fabiankeil
- * Remove FEATURE_COOKIE_JAR.
- *
- * Revision 1.184 2008/08/22 15:34:45 fabiankeil
- * - Silence LLVM/Clang complaint.
- * - Make received_hup_signal static.
- * - Hide definitions for basedir, pidfile and received_hup_signal
- * from __EMX__ as they only seem to be used in case of #ifdef unix.
- *
- * Revision 1.183 2008/08/21 07:09:35 fabiankeil
- * Accept Shoutcast responses again. Problem reported
- * and fix suggested by Stefan in #2062860.
- *
- * Revision 1.182 2008/06/27 11:13:56 fabiankeil
- * Fix possible NULL-pointer dereference reported
- * by din_a4 in #2003937. Pointy hat to me.
- *
- * Revision 1.181 2008/05/21 15:47:15 fabiankeil
- * Streamline sed()'s prototype and declare
- * the header parse and add structures static.
- *
- * Revision 1.180 2008/05/21 15:26:32 fabiankeil
- * - Mark csp as immutable for send_crunch_response().
- * - Fix comment spelling.
- *
- * Revision 1.179 2008/05/20 20:13:32 fabiankeil
- * Factor update_server_headers() out of sed(), ditch the
- * first_run hack and make server_patterns_light static.
- *
- * Revision 1.178 2008/05/10 13:23:38 fabiankeil
- * Don't provide get_header() with the whole client state
- * structure when it only needs access to csp->iob.
- *
- * Revision 1.177 2008/05/10 11:51:12 fabiankeil
- * Make the "read the rest of the headers" loop a bit more readable.
- *
- * Revision 1.176 2008/05/10 11:37:57 fabiankeil
- * - Instead of logging when the IIS5 hack is enabled, log when it fails.
- * - Remove useless comment.
- *
- * Revision 1.175 2008/05/09 18:53:59 fabiankeil
- * Fix comment grammar.
- *
- * Revision 1.174 2008/05/07 18:05:53 fabiankeil
- * Remove the pointless buffer in client_protocol_is_unsupported().
- *
- * Revision 1.173 2008/05/06 15:09:00 fabiankeil
- * Least-effort fix for bug #1821930 (reported by Lee):
- * If the response doesn't look like HTTP,
- * tell the client and log the problem.
- *
- * Revision 1.172 2008/04/16 16:38:21 fabiankeil
- * Don't pass the whole csp structure to flush_socket()
- * when it only needs a file descriptor and a buffer.
- *
- * Revision 1.171 2008/03/27 18:27:25 fabiankeil
- * Remove kill-popups action.
- *
- * Revision 1.170 2008/03/06 16:33:46 fabiankeil

- *
- * Revision 1.169 2008/03/04 18:30:39 fabiankeil
- * Remove the treat-forbidden-connects-like-blocks action. We now
- * use the "blocked" page for forbidden CONNECT requests by default.
- *
- * Revision 1.168 2008/03/02 12:25:25 fabiankeil
- * Also use shiny new connect_port_is_forbidden() in jcc.c.
- *
- * Revision 1.167 2008/02/23 16:57:12 fabiankeil
- * Rename url_actions() to get_url_actions() and let it
- * use the standard parameter ordering.
- *
- * Revision 1.166 2008/02/23 16:33:43 fabiankeil
- * Let forward_url() use the standard parameter ordering
- * and mark its second parameter immutable.
- *
- * Revision 1.165 2008/02/02 19:36:56 fabiankeil
- * Remove the "Listening ... for local connections only" log message.
- * Whether or not remote connections are able to reach Privoxy is up
- * to the operating system.
- *
- * Revision 1.164 2007/12/16 18:32:46 fabiankeil
- * Prevent the log messages for CONNECT requests to unacceptable

- *
- * Revision 1.163 2007/12/13 01:47:11 david__schmidt
- * Make sure all console-mode apps get a usage() instance
- *

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

- *
- * Revision 1.160 2007/11/29 18:00:29 fabiankeil
- * Plug memory leak. Spotted by Valgrind, triggered by
- * Privoxy-Regression-Test feeding proxyfuzz.py.
- *
- * Revision 1.159 2007/11/24 14:34:09 fabiankeil
- * In the HTTP snipplets, refer to the client as client.

- * once for mingw32 and provide some more details.
- *
- * Revision 1.156 2007/11/01 18:20:58 fabiankeil
- * Initialize log module after initializing mutexes, future
- * deadlocks in that code should now work cross-platform.
- *
- * Revision 1.155 2007/10/23 20:12:45 fabiankeil
- * Fix first CSUCCEED line to end in \r\n as required by RFC1945.

- *
- * Revision 1.153 2007/10/14 14:12:41 fabiankeil
- * When in daemon mode, close stderr after the configuration file has been
- * parsed the first time. If logfile isn't set, stop logging. Fixes BR#897436.
- *
- * Revision 1.152 2007/10/04 18:03:34 fabiankeil
- * - Fix a crash when parsing invalid requests whose first header
- * is rejected by get_header(). Regression (re?)introduced
- * in r1.143 by yours truly.
- * - Move ACTION_VANILLA_WAFER handling into parsers.c's
- * client_cookie_adder() to make sure send-vanilla-wafer can be
- * controlled through tags (and thus regression-tested).
- *
- * Revision 1.151 2007/09/29 10:21:16 fabiankeil
- * - Move get_filter_function() from jcc.c to filters.c
- * so the filter functions can be static.
- * - Don't bother filtering body-less responses.
- *
- * Revision 1.150 2007/09/28 16:39:29 fabiankeil

- * Revision 1.149 2007/09/04 15:08:48 fabiankeil
- * Initialize req to NULL to make sure it's defined if the
- * first read_socket() call fails. Reported by icmp30.
- *
- * Revision 1.148 2007/08/26 16:47:13 fabiankeil
- * Add Stephen Gildea's --pre-chroot-nslookup patch [#1276666],
- * extensive comments moved to user manual.
- *
- * Revision 1.147 2007/08/25 14:42:40 fabiankeil
- * Don't crash if a broken header filter wiped out the request line.
- *
- * Revision 1.146 2007/08/20 17:09:32 fabiankeil
- * Fix byte_count calculation in case of flushes
- * and don't parse the server headers a second time.
- *
- * Revision 1.145 2007/08/19 13:13:31 fabiankeil
- * - If there's a connection problem after we already forwarded
- * parts of the original content, just hang up. Fixes BR#1776724.
- * - Fix warnings about unused code on mingw32.
- * - In case of flushes, calculate the byte count
- * less incorrectly (I think).
- *
- * Revision 1.144 2007/08/11 14:43:22 fabiankeil
- * Add some more prototypes for static functions.
- *
- * Revision 1.143 2007/08/05 13:58:19 fabiankeil
- * Comment out request_contains_null_bytes() until it's used again.
- *
- * Revision 1.142 2007/08/05 13:50:26 fabiankeil
- * #1763173 from Stefan Huehner: s@const static@static const@
- * and declare some more functions static.
- *
- * Revision 1.141 2007/08/04 09:56:23 fabiankeil
- * - Log rejected CONNECT requests with LOG_LEVEL_INFO
- * and explain why they were rejected in the first place.
- * - Fix the LOG_LEVEL_CLF message for crunches of unallowed
- * CONNECT requests. The request line was missing.
- * - Add two more XXX reminders as we don't have enough already.
- *
- * Revision 1.140 2007/07/21 11:51:36 fabiankeil
- * As Hal noticed, checking dispatch_cgi() as the last cruncher
- * looks like a bug if CGI requests are blocked unintentionally,
- * so don't do it unless the user enabled the new config option
- * "allow-cgi-request-crunching".
- *
- * Revision 1.139 2007/07/14 07:46:41 fabiankeil
- * - Allow to rewrite the request destination behind the client's back.
- * - Turn the weird-looking unconditional for loop that
- * reads the client request into a conditional while loop.
- * Move the stuff that only runs once out of the loop.
- * - Move parts of chat(), server_content_type() and the
- * necessary stuff to fix BR#1750917 into get_filter_function().
- *
- * Revision 1.138 2007/06/03 18:45:18 fabiankeil
- * Temporary workaround for BR#1730105.
- *
- * Revision 1.137 2007/06/01 18:16:36 fabiankeil
- * Use the same mutex for gethostbyname() and gethostbyaddr() to prevent
- * deadlocks and crashes on OpenBSD and possibly other OS with neither
- * gethostbyname_r() nor gethostaddr_r(). Closes BR#1729174.
- * Thanks to Ralf Horstmann for report and solution.
- *
- * Revision 1.136 2007/06/01 16:41:11 fabiankeil
- * Add forward-override{} to change the forwarding settings through
- * action sections. This is mainly interesting to forward different
- * clients differently (for example based on User-Agent or request
- * origin).
- *
- * Revision 1.135 2007/05/24 17:03:50 fabiankeil
- * - Let usage() mention the --chroot parameter.
- * - Use read_socket() consistently and always leave
- * the last buffer byte alone, even in cases where
- * null termination (currently) doesn't matter.
- *
- * Revision 1.134 2007/05/16 14:59:46 fabiankeil
- * - Fix config file loading on Unix if no config file is specified.
- * Since r1.97 Privoxy would always interpret the last argument as
- * config file, even if it's a valid command line option.
- * - Abort in case of unrecognized command line options. Closes #1719696.
- * - Remove a bunch of unnecessary strcpy() calls (yay for c&p without thinking).
- * - Replace the remaining strcpy() and strcat() calls with strlcpy() and strcat().
- *
- * Revision 1.133 2007/05/04 11:23:19 fabiankeil
- * - Don't rerun crunchers that only depend on the request URL.
- * - Don't count redirects and CGI requests as "blocked requests".
- *
- * Revision 1.132 2007/04/25 15:15:17 fabiankeil
- * Support crunching based on tags created by server-header taggers.
- *
- * Revision 1.131 2007/04/22 13:24:50 fabiankeil
- * Make HTTP snippets static (again). Add a Content-Type for those
- * with content so the browser doesn't guess it based on the URL.
- *
- * Revision 1.130 2007/04/19 13:47:34 fabiankeil
- * Move crunching and request line rebuilding out of chat().
- *
- * Revision 1.129 2007/04/15 16:39:20 fabiankeil
- * Introduce tags as alternative way to specify which
- * actions apply to a request. At the moment tags can be
- * created based on client and server headers.
- *
- * Revision 1.128 2007/03/25 16:55:54 fabiankeil
- * Don't CLF-log CONNECT requests twice.
- *
- * Revision 1.127 2007/03/20 13:53:17 fabiankeil
- * Log the source address for ACL-related connection drops.

- * Revision 1.126 2007/03/17 15:20:05 fabiankeil
- * New config option: enforce-blocks.
- *
- * Revision 1.125 2007/03/09 14:12:00 fabiankeil
- * - Move null byte check into separate function.
- * - Don't confuse the client with error pages
- * if a CONNECT request was already confirmed.
- *
- * Revision 1.124 2007/02/23 14:59:54 fabiankeil
- * Speed up NULL byte escaping and only log the complete
- * NULL byte requests with header debugging enabled.
- *
- * Revision 1.123 2007/02/21 18:42:10 fabiankeil
- * Answer requests that contain NULL bytes with
- * a custom response instead of waiting for more
- * data until the client eventually hangs up.
- *
- * Revision 1.122 2007/02/07 11:12:02 fabiankeil
- * - Move delivery and logging of crunched responses
- * from chat() into send_crunch_response().
- * - Display the reason for generating http_responses.
- * - Log the content length for LOG_LEVEL_CLF correctly
- * (still incorrect for some fixed responses).
- * - Reword an incorrect comment about
- * treat-forbidden-connects-like-blocks violating
- * the specs.
- * - Add some log messages.
- *
- * Revision 1.121 2007/01/27 10:52:56 fabiankeil
- * Move mutex initialization into separate
- * function and exit in case of errors.
- *
- * Revision 1.120 2007/01/26 14:18:42 fabiankeil
- * - Start to reduce chat()'s line count and move
- * parts of it into separate functions.
- * - Add "HTTP/1.1 100 Continue" hack for BR 756734.
- *
- * Revision 1.119 2007/01/25 14:02:30 fabiankeil
- * - Add Proxy-Agent header to HTTP snippets that are
- * supposed to reach HTTP clients only.
- * - Made a few CONNECT log messages more descriptive.
- * - Catch completely empty server responses (as seen
- * with Tor's fake ".noconnect" top level domain).
- * - Use shiny new "forwarding-failed" template for socks errors.
- *
- * Revision 1.118 2007/01/07 07:43:43 joergs
- * AmigaOS4 support added.
- *
- * Revision 1.117 2006/12/31 17:56:37 fabiankeil
- * Added config option accept-intercepted-requests
- * and disabled it by default.
- *
- * Revision 1.116 2006/12/29 19:08:22 fabiankeil
- * Reverted parts of my last commit
- * to keep error handling working.
- *
- * Revision 1.115 2006/12/29 17:38:57 fabiankeil
- * Fixed gcc43 conversion warnings.
- *

- * Silence compiler warning I introduced with my last commit.
- *
- * Revision 1.112 2006/12/26 17:31:41 fabiankeil
- * Mutex protect rand() if POSIX threading
- * is used, warn the user if that's not possible
- * and stop using it on _WIN32 where it could
- * cause crashes.

- * Revision 1.111 2006/12/23 16:15:06 fabiankeil
- * Don't prevent core dumps by catching SIGABRT.
- * It's rude and makes debugging unreasonable painful.
- *
- * Revision 1.110 2006/12/13 14:52:53 etresoft
- * Fix build failure on MacOS X. Global symbols can be either static or extern, but not both.
- *
- * Revision 1.109 2006/12/06 19:41:40 fabiankeil
- * Privoxy is now able to run as intercepting
- * proxy in combination with any packet filter
- * that does the port redirection. The destination
- * is extracted from the "Host:" header which
- * should be available for nearly all requests.
- *
- * Moved HTTP snipplets into jcc.c.
- * Added error message for gopher proxy requests.
- *
- * Revision 1.108 2006/11/28 15:38:51 fabiankeil
- * Only unlink the pidfile if it's actually used.
- *
- * Change order of interception checks to make
- * it possible to block or redirect requests for
- * the cgi pages.
- *
- * Revision 1.107 2006/11/13 19:05:51 fabiankeil
- * Make pthread mutex locking more generic. Instead of
- * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
- * and use mutex locking unless there is an _r function
- * available. Better safe than sorry.
- *
- * Fixes "./configure --disable-pthread" and should result
- * in less threading-related problems on pthread-using platforms,
- * but it still doesn't fix BR#1122404.
- *
- * Revision 1.106 2006/11/06 19:58:23 fabiankeil
- * Move pthread.h inclusion from jcc.c to jcc.h.
- * Fixes build on x86-freebsd1 (FreeBSD 5.4-RELEASE).
- *
- * Revision 1.105 2006/11/06 14:26:02 fabiankeil
- * Don't exit after receiving the second SIGHUP on Solaris.
- *
- * Fixes BR 1052235, but the same problem may exist on other
- * systems. Once 3.0.6 is out we should use sigset()
- * where available and see if it breaks anything.
- *
- * Revision 1.104 2006/09/23 13:26:38 roro
- * Replace TABs by spaces in source code.
- *
- * Revision 1.103 2006/09/21 12:54:43 fabiankeil
- * Fix +redirect{}. Didn't work with -fast-redirects.
- *
- * Revision 1.102 2006/09/06 13:03:04 fabiankeil
- * Respond with 400 and a short text message
- * if the client tries to use Privoxy as FTP proxy.
- *
- * Revision 1.101 2006/09/06 09:23:37 fabiankeil
- * Make number of retries in case of forwarded-connect problems
- * a config file option (forwarded-connect-retries) and use 0 as
- * default.
- *
- * Revision 1.100 2006/09/03 19:42:59 fabiankeil
- * Set random(3) seed.
- *
- * Revision 1.99 2006/09/02 15:36:42 fabiankeil
- * Follow the OpenBSD port's lead and protect the resolve
- * functions on OpenBSD as well.
- *
- * Revision 1.98 2006/08/24 11:01:34 fabiankeil
- * --user fix. Only use the user as group if no group is specified.
- * Solves BR 1492612. Thanks to Spinor S. and David Laight.
- *
- * Revision 1.97 2006/08/18 15:23:17 david__schmidt
- * Windows service (re-)integration
- *
- * The new args are:
- *
- * --install[:service_name]
- * --uninstall[:service_name]
- * --service
- *
- * They work as follows:
- * --install will create a service for you and then terminate.
- * By default the service name will be "privoxy" (without the quotes).
- * However you can run multiple services if you wish, just by adding
- * a colon and then a name (no spaces).
- *
- * --uninstall follows the exact same rules a --install.
- *
- * --service is used when the program is executed by the service
- * control manager, and in normal circumstances would never be
- * used as a command line argument.
- *
- * Revision 1.96 2006/08/15 20:12:36 david__schmidt
- * Windows service integration
- *
- * Revision 1.95 2006/08/03 02:46:41 david__schmidt

- *
- * Revision 1.94 2006/07/18 14:48:46 david__schmidt
- * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
- * with what was really the latest development (the v_3_0_branch branch)
- *
- * Revision 1.92.2.16 2005/04/03 20:10:50 david__schmidt
- * Thanks to Jindrich Makovicka for a race condition fix for the log

- *
- * Revision 1.92.2.15 2004/10/03 12:53:32 david__schmidt
- * Add the ability to check jpeg images for invalid
- * lengths of comment blocks. Defensive strategy
- * against the exploit:
- * Microsoft Security Bulletin MS04-028
- * Buffer Overrun in JPEG Processing (GDI+) Could
- * Allow Code Execution (833987)
- * Enabled with +inspect-jpegs in actions files.
- *
- * Revision 1.92.2.14 2003/12/12 12:52:53 oes
- * - Fixed usage info for non-unix platforms
- * - Fixed small cmdline parsing bug
- *
- * Revision 1.92.2.13 2003/11/27 19:20:27 oes
- * Diagnostics: Now preserve the returncode of pthread_create

- * Fixes bug #711001
- *
- * Revision 1.92.2.8 2003/03/31 13:12:32 oes
- * Replaced setenv() by posix-compliant putenv()
- * Thanks to Neil McCalden (nmcc AT users.sf.net).
- *
- * Revision 1.92.2.7 2003/03/17 16:48:59 oes
- * Added chroot ability, thanks to patch by Sviatoslav Sviridov
- *
- * Revision 1.92.2.6 2003/03/11 11:55:00 oes
- * Clean-up and extension of improvements for forked mode:
- * - Child's return code now consists of flags RC_FLAG_*
- * - Reporting toggle to parent now properly #ifdef'ed
- * - Children now report blocking to parent. This enables
- * statistics in forked mode
- *
- * Revision 1.92.2.5 2003/03/10 23:45:32 oes
- * Fixed bug #700381: Non-Threaded version now capable of being toggled.
- * Children now report having been toggled through _exit(17), parents
- * watch for that code and toggle themselves if found.
- *
- * Revision 1.92.2.4 2003/03/07 03:41:04 david__schmidt
- * Wrapping all *_r functions (the non-_r versions of them) with
- * mutex semaphores for OSX. Hopefully this will take care of all
- * of those pesky crash reports.
- *
- * Revision 1.92.2.3 2003/02/28 12:53:06 oes
- * Fixed two mostly harmless mem leaks
- *
- * Revision 1.92.2.2 2002/11/20 14:37:47 oes
- * Fix: Head of global clients list now initialized to NULL
- *
- * Revision 1.92.2.1 2002/09/25 14:52:24 oes
- * Added basic support for OPTIONS and TRACE HTTP methods:
- * - New interceptor direct_response() added in chat().
- * - sed() moved to earlier in the process, so that the
- * Host: header is evaluated before actions and forwarding
- * are decided on.
- *
- * Revision 1.92 2002/05/08 16:00:46 oes
- * Chat's buffer handling:
- * - Fixed bug with unchecked out-of-mem conditions
- * while reading client request & server headers
- * - No longer predict if the buffer limit will be exceeded
- * in the next read -- check add_to_iob's new
- * return code. If buffer couldn't be extended
- * (policy or out-of-mem) while
- * - reading from client: abort
- * - reading server headers: send error page
- * - buffering server body for filter: flush,
- * and if that fails: send error page
- *
- * Revision 1.91 2002/04/08 20:35:58 swa
- * fixed JB spelling
- *
- * Revision 1.90 2002/04/02 14:57:28 oes

- * Workaround for closing the jarfile before load_config() comes around again
- *
- * Revision 1.85 2002/03/24 15:23:33 jongfoster
- * Name changes
- *
- * Revision 1.84 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.83 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.82 2002/03/13 00:27:05 jongfoster
- * Killing warnings
- *
- * Revision 1.81 2002/03/12 01:42:50 oes
- * Introduced modular filters
- *
- * Revision 1.80 2002/03/11 22:07:05 david__schmidt
- * OS/2 port maintenance:
- * - Fixed EMX build - it had decayed a little
- * - Fixed inexplicable crash during FD_ZERO - must be due to a bad macro.
- * substituted a memset for now.
- *
- * Revision 1.79 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.78 2002/03/08 21:35:04 oes
- * Added optional group supplement to --user option. Will now use default group of user if no group given
- *
- * Revision 1.77 2002/03/07 03:52:06 oes
- * - Fixed compiler warnings etc
- * - Improved handling of failed DNS lookups
- *
- * Revision 1.76 2002/03/06 22:54:35 jongfoster
- * Automated function-comment nitpicking.
- *
- * Revision 1.75 2002/03/06 10:02:19 oes
- * Fixed stupid bug when --user was not given
- *
- * Revision 1.74 2002/03/06 00:49:31 jongfoster
- * Fixing warning on Windows
- * Making #ifdefs that refer to the same variable consistently
- * use #ifdef unix rather than mixing #ifdef unix & #ifndef OS2
- *
- * Revision 1.73 2002/03/05 23:57:30 hal9
- * Stray character 's' on line 1618 was breaking build.
- *
- * Revision 1.72 2002/03/05 21:33:45 david__schmidt
- * - Re-enable OS/2 building after new parms were added
- * - Fix false out of memory report when resolving CGI templates when no IP
- * address is available of failed attempt (a la no such domain)
- *
- * Revision 1.71 2002/03/05 18:13:56 oes

- * - Cleand up cmdline parsing
- * - Introduced --no-daemon, --pidfile options
- * - Cleaned up signal handling:
- * - Terminate cleanly on INT, TERM and ABRT
- * - Schedule logfile for re-opening on HUP
- * - Ignore CHLD and PIPE
- * - Leave the rest with their default handlers
- * - Uniform handler registration
- * - Added usage() function
- * - Played styleguide police

- *
- * Revision 1.58 2001/11/30 23:37:24 jongfoster
- * Renaming the Win32 config file to config.txt - this is almost the
- * same as the corresponding UNIX name "config"
- *
- * Revision 1.57 2001/11/16 00:47:43 jongfoster
- * Changing the tty-disconnection code to use setsid().

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

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

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

- * Revision 1.25 2001/07/15 19:43:49 jongfoster
- * Supports POSIX threads.
- * Also removed some unused #includes.
- *
- * Revision 1.24 2001/07/13 14:00:40 oes
- * - Generic content modification scheme:
- * Each feature has its own applicability flag that is set
- * from csp->action->flags.
- * Replaced the "filtering" int flag , by a function pointer
- * "content_filter" to the function that will do the content
- * modification. If it is != NULL, the document will be buffered
- * and processed through *content_filter, which must set
- * csp->content_length and return a modified copy of the body
- * or return NULL (on failiure).
- * - Changed csp->is_text to the more generic bitmap csp->content_type
- * which can currently take the valued CT_TEXT or CT_GIF
- * - Reformatting etc
- * - Removed all #ifdef PCRS
- *
- * Revision 1.23 2001/07/02 02:28:25 iwanttokeepanon
- * Added "#ifdef ACL_FILES" conditional compilation to line 1291 to exclude
- * the `block_acl' call. This prevents a compilation error when the user
- * does not wish to use the "ACL" feature.
- *
- * Revision 1.22 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space

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

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

- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple

- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a

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

- *
- * Revision 1.78 2008/08/02 08:23:22 fabiankeil
- * If the enforce-blocks directive is used with FEATURE_FORCE_LOAD

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

- *
- * Formatting changed to Privoxy style, added call to
- * cgi_error_no_template if the requested file doesn't
- * exist and modified check whether or not Privoxy itself
- * should serve the manual. Should work cross-platform now.
- *
- * Revision 1.52 2006/09/06 10:43:32 fabiankeil
- * Added config option enable-remote-http-toggle
- * to specify if Privoxy should recognize special
- * headers (currently only X-Filter) to change its
- * behaviour. Disabled by default.
- *
- * Revision 1.51 2006/09/06 09:23:37 fabiankeil
- * Make number of retries in case of forwarded-connect problems

- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program

- * Add '-d' if compiled with 'configure --with-debug' to
- * enable debug output.
- *
- * Revision 1.25 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.24 2001/10/23 21:40:30 jongfoster

- * Fixed minor memory leak.
- * Also now uses make_path to prepend the pathnames.
- *
- * Revision 1.12 2001/06/05 20:04:09 jongfoster
- * Now uses _snprintf() in place of snprintf() under Win32.
- *
- * Revision 1.11 2001/06/04 18:31:58 swa
- * files are now prefixed with either `confdir' or `logdir'.
- * `make redhat-dist' replaces both entries confdir and logdir
- * with redhat values
- *
- * Revision 1.10 2001/06/03 19:11:54 oes
- * introduced confdir option
- *
- * Revision 1.9 2001/06/01 20:06:24 jongfoster
- * Removed support for "tinygif" option - moved to actions file.
- *
- * Revision 1.8 2001/05/31 21:27:13 jongfoster
- * Removed many options from the config file and into the
- * "actions" file: add_forwarded, suppress_vanilla_wafer,
- * wafer, add_header, user_agent, referer, from
- * Also globally replaced "permission" with "action".
- *
- * Revision 1.7 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.6 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.5 2001/05/25 22:34:30 jongfoster
- * Hard tabs->Spaces
- *
- * Revision 1.4 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.3 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.2 2001/05/17 23:01:01 oes
- * - Cleaned CRLF's from the sources and related files
- *
- * Revision 1.1.1.1 2001/05/15 13:58:58 oes
- * Initial import of version 2.9.3 source tree

- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand

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

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

- * Revision 1.53 2006/08/31 16:25:06 fabiankeil

- * Revision 1.36 2002/01/22 23:46:18 jongfoster
- * Moving edit_read_line() and simple_read_line() to loaders.c, and
- * extending them to support reading MS-DOS, Mac and UNIX style files
- * on all platforms.
- *
- * Modifying read_config_line() (without changing it's prototype) to
- * be a trivial wrapper for edit_read_line(). This means that we have
- * one function to read a line and handle comments, which is common
- * between the initialization code and the edit interface.
- *
- * Revision 1.35 2002/01/17 21:03:08 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *

- * Add line number in error output for lineparsing for
- * actionsfile and configfile.
- * Special handling for CLF added.
- *
- * Revision 1.31 2001/10/26 17:39:01 oes
- * Removed csp->referrer
- * Moved ijb_isspace and ijb_tolower to project.h
- *
- * Revision 1.30 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.29 2001/10/23 21:38:53 jongfoster
- * Adding error-checking to create_url_spec()
- *
- * Revision 1.28 2001/10/07 15:40:39 oes

- * file are now permitted.

- *
- * Revision 1.25 2001/09/13 22:44:03 jongfoster
- * Adding {} to an if statement
- *
- * Revision 1.24 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:

- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.23 2001/07/20 15:51:54 oes
- * Fixed indentation of prepocessor commands
- *
- * Revision 1.22 2001/07/20 15:16:17 haroon
- * - per Guy's suggestion, added a while loop in sweep() to catch not just
- * the last inactive CSP but all other consecutive inactive CSPs after that
- * as well
- *
- * Revision 1.21 2001/07/18 17:26:24 oes
- * Changed to conform to new pcrs interface

- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.15 2001/06/07 23:14:14 jongfoster
- * Removing ACL and forward file loaders - these
- * files have been merged into the config file.
- * Cosmetic: Moving unloader funcs next to their
- * respective loader funcs
- *
- * Revision 1.14 2001/06/01 03:27:04 oes
- * Fixed line continuation problem
- *
- * Revision 1.13 2001/05/31 21:28:49 jongfoster
- * Removed all permissionsfile code - it's now called the actions
- * file, and (almost) all the code is in actions.c
- *
- * Revision 1.12 2001/05/31 17:32:31 oes
- *
- * - Enhanced domain part globbing with infix and prefix asterisk
- * matching and optional unanchored operation
- *
- * Revision 1.11 2001/05/29 23:25:24 oes

- *
- * Revision 1.10 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.9 2001/05/26 17:12:07 jongfoster
- * Fatal errors loading configuration files now give better error messages.
- *
- * Revision 1.8 2001/05/26 00:55:20 jongfoster

- *
- * Revision 1.7 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.6 2001/05/23 12:27:33 oes
- *
- * Fixed ugly indentation of my last changes
- *
- * Revision 1.5 2001/05/23 10:39:05 oes
- * - Added support for escaping the comment character
- * in config files by a backslash
- * - Added support for line continuation in config
- * files
- * - Fixed a buffer overflow bug with long config lines
- *
- * Revision 1.4 2001/05/22 18:56:28 oes

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

- * Revision 1.6 2001/06/03 19:12:30 oes
- * introduced bindup()
- *
- * Revision 1.5 2001/06/01 10:31:51 oes
- * Added character class matching to trivimatch; renamed to simplematch
- *
- * Revision 1.4 2001/05/31 17:32:31 oes
- *
- * - Enhanced domain part globbing with infix and prefix asterisk
- * matching and optional unanchored operation
- *
- * Revision 1.3 2001/05/29 23:10:09 oes

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

- *
- * Revision 1.149 2008/11/21 18:39:53 fabiankeil
- * In case of CONNECT requests there's no point

- *
- * Revision 1.148 2008/11/16 12:43:49 fabiankeil

- *
- * Revision 1.135 2008/05/21 20:12:10 fabiankeil
- * The whole point of strclean() is to modify the
- * first parameter, so don't mark it immutable,

- *
- * Revision 1.126 2008/05/03 16:40:45 fabiankeil
- * Change content_filters_enabled()'s parameter from
- * csp->action to action so it can be also used in the
- * CGI code. Don't bother checking if there are filters

- *
- * Revision 1.125 2008/04/17 14:40:49 fabiankeil
- * Provide get_http_time() with the buffer size so it doesn't
- * have to blindly assume that the buffer is big enough.
- *
- * Revision 1.124 2008/04/16 16:38:21 fabiankeil
- * Don't pass the whole csp structure to flush_socket()

- * Revision 1.120 2008/01/04 17:43:45 fabiankeil
- * Improve the warning messages that get logged if the action files
- * "enable" filters but no filters of that type have been loaded.
- *
- * Revision 1.119 2007/12/28 18:32:51 fabiankeil
- * In server_content_type():
- * - Don't require leading white space when detecting image content types.

- * type actually is 'text/plain'.
- * - Mark the 'text/plain == binary data' assumption for removal.

- * - Downgrade "Buffer limit reached" message to LOG_LEVEL_INFO.

- * Remove Range and If-Range headers if content filtering is enabled.
- *
- * Revision 1.111 2007/10/04 18:07:00 fabiankeil
- * Move ACTION_VANILLA_WAFER handling from jcc's chat() into
- * client_cookie_adder() to make sure send-vanilla-wafer can be
- * controlled through tags (and thus regression-tested).

- *
- * Revision 1.107 2007/08/28 18:16:32 fabiankeil

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

- * Part of the fix for BR#1750917.
- *
- * Revision 1.103 2007/06/01 16:31:54 fabiankeil

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

- * Revision 1.99 2007/04/30 15:06:26 fabiankeil
- * - Introduce dynamic pcrs jobs that can resolve variables.
- * - Remove unnecessary update_action_bits_for_all_tags() call.
- *
- * Revision 1.98 2007/04/17 18:32:10 fabiankeil
- * - Make tagging based on tags set by earlier taggers
- * of the same kind possible.
- * - Log whether or not new tags cause action bits updates
- * (in which case a matching tag-pattern section exists).
- * - Log if the user tries to set a tag that is already set.
- *
- * Revision 1.97 2007/04/15 16:39:21 fabiankeil
- * Introduce tags as alternative way to specify which
- * actions apply to a request. At the moment tags can be
- * created based on client and server headers.
- *
- * Revision 1.96 2007/04/12 12:53:58 fabiankeil
- * Log a warning if the content is compressed, filtering is
- * enabled and Privoxy was compiled without zlib support.
- * Closes FR#1673938.
- *
- * Revision 1.95 2007/03/25 14:26:40 fabiankeil
- * - Fix warnings when compiled with glibc.
- * - Don't use crumble() for cookie crunching.

- * - Log the content size after decompression in decompress_iob()
- * instead of pcrs_filter_response().
- *
- * Revision 1.93 2007/03/20 15:21:44 fabiankeil
- * - Use dedicated header filter actions instead of abusing "filter".
- * Replace "filter-client-headers" and "filter-client-headers"
- * with "server-header-filter" and "client-header-filter".
- * - Remove filter_client_header() and filter_client_header(),
- * filter_header() now checks the shiny new
- * CSP_FLAG_CLIENT_HEADER_PARSING_DONE flag instead.
- *
- * Revision 1.92 2007/03/05 13:25:32 fabiankeil
- * - Cosmetical changes for LOG_LEVEL_RE_FILTER messages.
- * - Handle "Cookie:" and "Connection:" headers a bit smarter
- * (don't crunch them just to recreate them later on).
- * - Add another non-standard time format for the cookie
- * expiration date detection.
- * - Fix a valgrind warning.
- *
- * Revision 1.91 2007/02/24 12:27:32 fabiankeil

- *
- * Revision 1.90 2007/02/08 19:12:35 fabiankeil

- * sed() parses server headers; only adjust the
- * Content-Length header if the page was modified.
- *
- * Revision 1.89 2007/02/07 16:52:11 fabiankeil
- * Fix log messages regarding the cookie time format
- * (cookie and request URL were mixed up).
- *
- * Revision 1.88 2007/02/07 11:27:12 fabiankeil
- * - Let decompress_iob()
- * - not corrupt the content if decompression fails
- * early. (the first byte(s) were lost).
- * - use pointer arithmetics with defined outcome for
- * a change.
- * - Use a different kludge to remember a failed decompression.
- *
- * Revision 1.87 2007/01/31 16:21:38 fabiankeil
- * Search for Max-Forwards headers case-insensitive,
- * don't generate the "501 unsupported" message for invalid
- * Max-Forwards values and don't increase negative ones.
- *
- * Revision 1.86 2007/01/30 13:05:26 fabiankeil
- * - Let server_set_cookie() check the expiration date
- * of cookies and don't touch the ones that are already
- * expired. Fixes problems with low quality web applications
- * as described in BR 932612.
- *
- * - Adjust comment in client_max_forwards to reality;
- * remove invalid Max-Forwards headers.
- *
- * Revision 1.85 2007/01/26 15:33:46 fabiankeil
- * Stop filter_header() from unintentionally removing
- * empty header lines that were enlisted by the continue
- * hack.
- *
- * Revision 1.84 2007/01/24 12:56:52 fabiankeil
- * - Repeat the request URL before logging any headers.
- * Makes reading the log easier in case of simultaneous requests.
- * - If there are more than one Content-Type headers in one request,
- * use the first one and remove the others.
- * - Remove "newval" variable in server_content_type().
- * It's only used once.
- *
- * Revision 1.83 2007/01/12 15:03:02 fabiankeil
- * Correct a cast, check inflateEnd() exit code
- * to see if we have to, replace sprintf calls
- * with snprintf.
- *
- * Revision 1.82 2007/01/01 19:36:37 fabiankeil
- * Integrate a modified version of Wil Mahan's
- * zlib patch (PR #895531).
- *
- * Revision 1.81 2006/12/31 22:21:33 fabiankeil
- * Skip empty filter files in filter_header()
- * but don't ignore the ones that come afterwards.
- * Fixes BR 1619208, this time for real.
- *
- * Revision 1.80 2006/12/29 19:08:22 fabiankeil
- * Reverted parts of my last commit
- * to keep error handling working.
- *
- * Revision 1.79 2006/12/29 18:04:40 fabiankeil
- * Fixed gcc43 conversion warnings.
- *
- * Revision 1.78 2006/12/26 17:19:20 fabiankeil
- * Bringing back the "useless" localtime() call
- * I removed in revision 1.67. On some platforms
- * it's necessary to prevent time zone offsets.
- *
- * Revision 1.77 2006/12/07 18:44:26 fabiankeil
- * Rebuild request URL in get_destination_from_headers()
- * to make sure redirect{pcrs command} works as expected
- * for intercepted requests.
- *
- * Revision 1.76 2006/12/06 19:52:25 fabiankeil
- * Added get_destination_from_headers().
- *
- * Revision 1.75 2006/11/13 19:05:51 fabiankeil
- * Make pthread mutex locking more generic. Instead of
- * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
- * and use mutex locking unless there is an _r function
- * available. Better safe than sorry.
- *
- * Fixes "./configure --disable-pthread" and should result
- * in less threading-related problems on pthread-using platforms,
- * but it still doesn't fix BR#1122404.
- *
- * Revision 1.74 2006/10/02 16:59:12 fabiankeil
- * The special header "X-Filter: No" now disables
- * header filtering as well.
- *
- * Revision 1.73 2006/09/23 13:26:38 roro
- * Replace TABs by spaces in source code.
- *
- * Revision 1.72 2006/09/23 12:37:21 fabiankeil
- * Don't print a log message every time filter_headers is
- * entered or left. It only creates noise without any real
- * information.
- *
- * Revision 1.71 2006/09/21 19:55:17 fabiankeil
- * Fix +hide-if-modified-since{-n}.
- *
- * Revision 1.70 2006/09/08 12:06:34 fabiankeil
- * Have hide-if-modified-since interpret the random
- * range value as minutes instead of hours. Allows
- * more fine-grained configuration.
- *
- * Revision 1.69 2006/09/06 16:25:51 fabiankeil
- * Always have parse_header_time return a pointer
- * that actual makes sense, even though we currently
- * only need it to detect problems.
- *
- * Revision 1.68 2006/09/06 10:43:32 fabiankeil
- * Added config option enable-remote-http-toggle
- * to specify if Privoxy should recognize special
- * headers (currently only X-Filter) to change its
- * behaviour. Disabled by default.
- *
- * Revision 1.67 2006/09/04 11:01:26 fabiankeil
- * After filtering de-chunked instances, remove
- * "Transfer-Encoding" header entirely instead of changing
- * it to "Transfer-Encoding: identity", which is invalid.
- * Thanks Michael Shields <shields@msrl.com>. Fixes PR 1318658.
- *
- * Don't use localtime in parse_header_time. An empty time struct
- * is good enough, it gets overwritten by strptime anyway.
- *
- * Revision 1.66 2006/09/03 19:38:28 fabiankeil
- * Use gmtime_r if available, fallback to gmtime with mutex
- * protection for MacOSX and use vanilla gmtime for the rest.
- *
- * Revision 1.65 2006/08/22 10:55:56 fabiankeil
- * Changed client_referrer to use the right type (size_t) for
- * hostlenght and to shorten the temporary referrer string with
- * '\0' instead of adding a useless line break.
- *
- * Revision 1.64 2006/08/17 17:15:10 fabiankeil
- * - Back to timegm() using GnuPG's replacement if necessary.
- * Using mktime() and localtime() could add a on hour offset if
- * the randomize factor was big enough to lead to a summer/wintertime
- * switch.
- *
- * - Removed now-useless Privoxy 3.0.3 compatibility glue.
- *
- * - Moved randomization code into pick_from_range().
- *
- * - Changed parse_header_time definition.
- * time_t isn't guaranteed to be signed and
- * if it isn't, -1 isn't available as error code.
- * Changed some variable types in client_if_modified_since()
- * because of the same reason.
- *
- * Revision 1.63 2006/08/14 13:18:08 david__schmidt
- * OS/2 compilation compatibility fixups

- * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
- * with what was really the latest development (the v_3_0_branch branch)
- *
- * Revision 1.56.2.10 2006/01/21 16:16:08 david__schmidt
- * Thanks to Edward Carrel for his patch to modernize OSX's\rpthreads support. See bug #1409623.
- *
- * Revision 1.56.2.9 2004/10/03 12:53:45 david__schmidt
- * Add the ability to check jpeg images for invalid
- * lengths of comment blocks. Defensive strategy
- * against the exploit:
- * Microsoft Security Bulletin MS04-028
- * Buffer Overrun in JPEG Processing (GDI+) Could
- * Allow Code Execution (833987)
- * Enabled with +inspect-jpegs in actions files.
- *
- * Revision 1.56.2.8 2003/07/11 13:21:25 oes
- * Excluded text/plain objects from filtering. This fixes a
- * couple of client-crashing, download corruption and
- * Privoxy performance issues, whose root cause lies in
- * web servers labelling content of unknown type as text/plain.
- *
- * Revision 1.56.2.7 2003/05/06 12:07:26 oes
- * Fixed bug #729900: Suspicious HOST: headers are now killed and regenerated if necessary

- * Fix typo: supressed -> suppressed
- *
- * Revision 1.56.2.2 2002/09/25 14:59:53 oes
- * Improved cookie logging
- *
- * Revision 1.56.2.1 2002/09/25 14:52:45 oes
- * Added basic support for OPTIONS and TRACE HTTP methods:
- * - New parser function client_max_forwards which decrements
- * the Max-Forwards HTTP header field of OPTIONS and TRACE
- * requests by one before forwarding
- * - New parser function client_host which extracts the host
- * and port information from the HTTP header field if the
- * request URI was not absolute
- * - Don't crumble and re-add the Host: header, but only generate
- * and append if missing
- *
- * Revision 1.56 2002/05/12 15:34:22 jongfoster
- * Fixing typo in a comment
- *
- * Revision 1.55 2002/05/08 16:01:07 oes
- * Optimized add_to_iob:
- * - Use realloc instead of malloc(), memcpy(), free()
- * - Expand to powers of two if possible, to get
- * O(log n) reallocs instead of O(n).
- * - Moved check for buffer limit here from chat
- * - Report failure via returncode
- *
- * Revision 1.54 2002/04/02 15:03:16 oes
- * Tiny code cosmetics
- *
- * Revision 1.53 2002/03/26 22:29:55 swa

- *
- * Revision 1.51 2002/03/13 00:27:05 jongfoster
- * Killing warnings
- *
- * Revision 1.50 2002/03/12 01:45:35 oes
- * More verbose logging
- *
- * Revision 1.49 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.48 2002/03/07 03:46:53 oes
- * Fixed compiler warnings etc
- *
- * Revision 1.47 2002/02/20 23:15:13 jongfoster
- * Parsing functions now handle out-of-memory gracefully by returning
- * an error code.
- *
- * Revision 1.46 2002/01/17 21:03:47 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Revision 1.45 2002/01/09 14:33:03 oes
- * Added support for localtime_r.
- *
- * Revision 1.44 2001/12/14 01:22:54 steudten
- * Remove 'user:pass@' from 'proto://user:pass@host' for the
- * new added header 'Host: ..'. (See Req ID 491818)
- *
- * Revision 1.43 2001/11/23 00:26:38 jongfoster
- * Fixing two really stupid errors in my previous commit
- *
- * Revision 1.42 2001/11/22 21:59:30 jongfoster
- * Adding code to handle +no-cookies-keep
- *
- * Revision 1.41 2001/11/05 23:43:05 steudten
- * Add time+date to log files.
- *
- * Revision 1.40 2001/10/26 20:13:09 jongfoster
- * ctype.h is needed in Windows, too.
- *
- * Revision 1.39 2001/10/26 17:40:04 oes
- * Introduced get_header_value()
- * Removed http->user_agent, csp->referrer and csp->accept_types
- * Removed client_accept()
- *
- * Revision 1.38 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.37 2001/10/23 21:36:02 jongfoster
- * Documenting sed()'s error behaviou (doc change only)
- *
- * Revision 1.36 2001/10/13 12:51:51 joergs
- * Removed client_host, (was only required for the old 2.0.2-11 http://noijb.
- * force-load), instead crumble Host: and add it (again) in client_host_adder
- * (in case we get a HTTP/1.0 request without Host: header and forward it to
- * a HTTP/1.1 server/proxy).
- *
- * Revision 1.35 2001/10/09 22:39:21 jongfoster
- * assert.h is also required under Win32, so moving out of #ifndef _WIN32
- * block.
- *
- * Revision 1.34 2001/10/07 18:50:55 oes
- * Added server_content_encoding, renamed server_transfer_encoding
- *
- * Revision 1.33 2001/10/07 18:04:49 oes
- * Changed server_http11 to server_http and its pattern to "HTTP".
- * Additional functionality: it now saves the HTTP status into
- * csp->http->status and sets CT_TABOO for Status 206 (partial range)
- *
- * Revision 1.32 2001/10/07 15:43:28 oes
- * Removed FEATURE_DENY_GZIP and replaced it with client_accept_encoding,
- * client_te and client_accept_encoding_adder, triggered by the new
- * +no-compression action. For HTTP/1.1 the Accept-Encoding header is
- * changed to allow only identity and chunked, and the TE header is
- * crunched. For HTTP/1.0, Accept-Encoding is crunched.
- *
- * parse_http_request no longer does anything than parsing. The rewriting
- * of http->cmd and version mangling are gone. It now also recognizes
- * the put and delete methods and saves the url in http->url. Removed
- * unused variable.
- *
- * renamed content_type and content_length to have the server_ prefix
- *
- * server_content_type now only works if csp->content_type != CT_TABOO
- *
- * added server_transfer_encoding, which
- * - Sets CT_TABOO to prohibit filtering if encoding compresses
- * - Raises the CSP_FLAG_CHUNKED flag if Encoding is "chunked"
- * - Change from "chunked" to "identity" if body was chunked
- * but has been de-chunked for filtering.
- *
- * added server_content_md5 which crunches any Content-MD5 headers
- * if the body was modified.
- *
- * made server_http11 conditional on +downgrade action
- *
- * Replaced 6 boolean members of csp with one bitmap (csp->flags)
- *
- * Revision 1.31 2001/10/05 14:25:02 oes
- * Crumble Keep-Alive from Server
- *
- * Revision 1.30 2001/09/29 12:56:03 joergs
- * 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

- * remove local variable shadow s2
- *
- * Revision 1.26 2001/09/16 17:05:14 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

- * - 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

- * - Back to timegm() using GnuPG's replacement if necessary.
- * Using mktime() and localtime() could add a on hour offset if
- * the randomize factor was big enough to lead to a summer/wintertime
- * switch.
- *
- * - Removed now-useless Privoxy 3.0.3 compatibility glue.
- *
- * - Moved randomization code into pick_from_range().
- *
- * - Changed parse_header_time definition.
- * time_t isn't guaranteed to be signed and
- * if it isn't, -1 isn't available as error code.
- * Changed some variable types in client_if_modified_since()
- * because of the same reason.
- *
- * Revision 1.30 2006/08/14 08:25:19 fabiankeil
- * Split filter-headers{} into filter-client-headers{}
- * and filter-server-headers{}.
- * Added parse_header_time() to share some code.
- * Replaced timegm() with mktime().
- *
- * Revision 1.29 2006/08/03 02:46:41 david__schmidt
- * Incorporate Fabian Keil's patch work:\rhttp://www.fabiankeil.de/sourcecode/privoxy/
- *
- * Revision 1.28 2006/07/18 14:48:47 david__schmidt
- * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
- * with what was really the latest development (the v_3_0_branch branch)
- *
- * Revision 1.26.2.1 2002/09/25 14:52:46 oes
- * Added basic support for OPTIONS and TRACE HTTP methods:
- * - New parser function client_max_forwards which decrements
- * the Max-Forwards HTTP header field of OPTIONS and TRACE
- * requests by one before forwarding
- * - New parser function client_host which extracts the host
- * and port information from the HTTP header field if the
- * request URI was not absolute
- * - Don't crumble and re-add the Host: header, but only generate
- * and append if missing
- *
- * Revision 1.26 2002/05/08 15:59:53 oes
- * Changed add_to_iob signature (now returns jb_err)
- *
- * Revision 1.25 2002/03/26 22:29:55 swa
- * we have a new homepage!

- * name change related issues
- *
- * Revision 1.23 2002/03/13 00:27:05 jongfoster
- * Killing warnings
- *
- * Revision 1.22 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.21 2002/03/07 03:46:17 oes
- * Fixed compiler warnings
- *
- * Revision 1.20 2002/02/20 23:15:13 jongfoster

- *
- * Revision 1.12 2001/09/13 23:05:50 jongfoster

- *
- * Revision 1.11 2001/07/31 14:46:53 oes
- * Added prototype for connection_close_adder
- *
- * Revision 1.10 2001/07/30 22:08:36 jongfoster

- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.9 2001/07/29 18:43:08 jongfoster
- * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
- * ANSI C rules.
- *
- * Revision 1.8 2001/07/13 14:01:54 oes

- * 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.

- * improved comments
- * - Removed my_strsep
- * - Replaced globalflag with a general flags int
- * that holds PCRS_GLOBAL, PCRS_SUCCESS, and PCRS_TRIVIAL
- * - Introduced trivial option that will prevent pcrs
- * from honouring backreferences in the substitute,
- * which is useful for large substitutes that are
- * red in from somewhere and saves the pain of escaping
- * the backrefs
- * - Introduced convenience function pcrs_free_joblist()
- * - Split pcrs_make_job() into pcrs_compile(), which still
- * takes a complete s/// comand as argument and parses it,
- * and a new function pcrs_make_job, which takes the
- * three separate components. This should make for a
- * much friendlier frontend.
- * - Removed create_pcrs_job() which was useless
- * - Fixed a bug in pcrs_execute

- * Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).

- *
- * Revision 1.128 2009/03/07 13:09:17 fabiankeil

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

- *
- * Revision 1.106 2008/03/24 11:21:03 fabiankeil
- * Share the action settings for multiple patterns in the same
- * section so we waste less memory for gigantic block lists
- * (and load them slightly faster). Reported by Franz Schwartau.
- *
- * Revision 1.105 2008/03/21 11:16:27 fabiankeil

- * Revision 1.98 2007/07/14 07:31:26 fabiankeil

- * Fixing bug with CT_TABOO
- *
- * Revision 1.55 2002/03/12 01:42:50 oes
- * Introduced modular filters
- *
- * Revision 1.54 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.53 2002/03/08 16:48:55 oes
- * Added FEATURE_NO_GIFS and BUILTIN_IMAGE_MIMETYPE
- *
- * Revision 1.52 2002/03/07 03:46:17 oes

- *
- * Revision 1.47 2002/02/20 23:15:13 jongfoster
- * Parsing functions now handle out-of-memory gracefully by returning
- * an error code.
- *
- * Revision 1.46 2002/01/17 21:06:09 jongfoster
- * Now #defining the URLs of the config interface
- *
- * Minor changes to struct http_request and struct url_spec due to
- * standardizing that struct http_request is used to represent a URL, and
- * struct url_spec is used to represent a URL pattern. (Before, URLs were
- * represented as seperate variables and a partially-filled-in url_spec).
- *
- * Revision 1.45 2002/01/09 14:33:27 oes
- * Added HOSTENT_BUFFER_SIZE
- *
- * Revision 1.44 2001/12/30 14:07:32 steudten

- * unsigned int.
- * Adding ACTION_NO_COOKIE_KEEP
- *
- * Revision 1.42 2001/11/05 21:42:41 steudten

- *
- * Revision 1.40 2001/10/26 17:40:47 oes
- * Moved ijb_isspace and ijb_tolower to project.h
- * Removed http->user_agent, csp->referrer and csp->accept_types
- *
- * Revision 1.39 2001/10/25 03:45:02 david__schmidt
- * Adding a (void*) cast to freez() because Visual Age C++ won't expand the
- * macro when called with a cast; so moving the cast to the macro def'n
- * seems to both eliminate compiler warnings (on darwin and OS/2, anyway) and
- * doesn't make macro expansion complain. Hope this works for everyone else
- * too...
- *
- * Revision 1.38 2001/10/23 21:19:04 jongfoster
- * New error-handling support: jb_err type and JB_ERR_xxx constants
- * CGI functions now return a jb_err, and their parameters map is const.
- * Support for RUNTIME_FEATUREs to enable/disable config editor
- * Adding a few comments
- *
- * Revision 1.37 2001/10/14 22:14:01 jongfoster
- * Removing name_length field from struct cgi_dispatcher, as this is
- * now calculated at runtime from the "name" field.
- *

- * Added status member to struct http_request
- *
- * Revision 1.34 2001/10/07 15:45:25 oes
- * Added url member to struct http_request and commented all
- * members
- *
- * Added CT_TABOO
- *
- * Added ACTION_DOWNGRADE and ACTION_NO_COMPRESSION
- *
- * Replaced struct client_state members rejected,
- * force, active and toggled_on with "flags" bitmap.
- *
- * Added CSP_FLAG_MODIFIED and CSP_FLAG_CHUNKED
- *
- * Added buffer_limit to struct configuration_spec
- *
- * Revision 1.33 2001/09/20 13:30:08 steudten
- *
- * Make freez() more secure in case of: if (exp) { free(z) ; a=*z }
- * Last case will set z to NULL in free(z) and thats bad..
- *
- * Revision 1.32 2001/09/16 23:02:51 jongfoster
- * Fixing warning
- *
- * Revision 1.31 2001/09/16 13:20:29 jongfoster
- * Rewrite of list library. Now has seperate header and list_entry
- * structures. Also added a large sprinking of assert()s to the list
- * code.

- * Support for both static and dynamically generated CGI pages
- *

- * Defining FORWARD_SPEC_INITIALIZER
- *
- * Revision 1.28 2001/09/13 23:05:50 jongfoster
- * Changing the string paramater to the header parsers a "const".
- *
- * Revision 1.27 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *
- * Revision 1.26 2001/07/30 22:08:36 jongfoster

- *
- * Revision 1.22 2001/07/15 17:51:41 jongfoster
- * Renaming #define STATIC to STATIC_PCRE
- *
- * Revision 1.21 2001/07/13 14:03:19 oes

- * comply to the scheme in configure.in
- * - Added csp->content_type and its CT_* keys

- *
- * Revision 1.20 2001/06/29 21:45:41 oes

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

- *
- * Revision 1.48 2009/04/17 11:27:49 fabiankeil
- * Petr Pisar's privoxy-3.0.12-ipv6-3.diff.
- *
- * Revision 1.47 2009/03/02 19:18:10 fabiankeil
- * Streamline parse_http_request()'s prototype. As
- * cparser pointed out it doesn't actually use csp.
- *
- * Revision 1.46 2009/02/11 19:31:32 fabiankeil
- * Reject request lines that end with neither HTTP/1.0 nor HTTP/1.1.

- * Silence bogus compiler warning.

- * If the method isn't CONNECT, reject URLs without protocol.
- *
- * Revision 1.41 2008/05/02 09:51:34 fabiankeil
- * In parse_http_url(), don't muck around with values
- * that are none of its business: require an initialized
- * http structure and never unset http->ssl.
- *
- * Revision 1.40 2008/04/23 16:12:28 fabiankeil
- * Free with freez().
- *
- * Revision 1.39 2008/04/22 16:27:42 fabiankeil
- * In parse_http_request(), remove a pointless
- * temporary variable and free the buffer earlier.
- *
- * Revision 1.38 2008/04/18 05:17:18 fabiankeil
- * Mark simplematch()'s parameters as immutable.
- *
- * Revision 1.37 2008/04/17 14:53:29 fabiankeil
- * Move simplematch() into urlmatch.c as it's only
- * used to match (old-school) domain patterns.
- *
- * Revision 1.36 2008/04/14 18:19:48 fabiankeil
- * Remove now-pointless cast in create_url_spec().
- *
- * Revision 1.35 2008/04/14 18:11:21 fabiankeil
- * The compiler might not notice it, but the buffer passed to
- * create_url_spec() is modified later on and thus shouldn't
- * be declared immutable.
- *
- * Revision 1.34 2008/04/13 13:32:07 fabiankeil
- * Factor URL pattern compilation out of create_url_spec().
- *
- * Revision 1.33 2008/04/12 14:03:13 fabiankeil
- * Remove an obvious comment and improve another one.
- *
- * Revision 1.32 2008/04/12 12:38:06 fabiankeil
- * Factor out duplicated code to compile host, path and tag patterns.
- *
- * Revision 1.31 2008/04/10 14:41:04 fabiankeil
- * Ditch url_spec's path member now that it's no longer used.
- *
- * Revision 1.30 2008/04/10 04:24:24 fabiankeil
- * Stop duplicating the plain text representation of the path regex
- * (and keeping the copy around). Once the regex is compiled it's no
- * longer useful.
- *
- * Revision 1.29 2008/04/10 04:17:56 fabiankeil
- * In url_match(), check the right member for NULL when determining
- * whether there's a path regex to execute. Looking for a plain-text
- * representation works as well, but it looks "interesting" and that
- * member will be removed soonish anyway.
- *
- * Revision 1.28 2008/04/08 16:07:39 fabiankeil
- * Make it harder to mistake url_match()'s
- * second parameter for an url_spec.
- *
- * Revision 1.27 2008/04/08 15:44:33 fabiankeil
- * Save a bit of memory (and a few cpu cycles) by not bothering to
- * compile slash-only path regexes that don't affect the result.
- *
- * Revision 1.26 2008/04/07 16:57:18 fabiankeil
- * - Use free_url_spec() more consistently.
- * - Let it reset url->dcount just in case.
- *
- * Revision 1.25 2008/04/06 15:18:38 fabiankeil
- * Oh well, rename the --enable-pcre-host-patterns option to
- * --enable-extended-host-patterns as it's not really PCRE syntax.
- *
- * Revision 1.24 2008/04/06 14:54:26 fabiankeil
- * Use PCRE syntax in host patterns when configured
- * with --enable-pcre-host-patterns.
- *
- * Revision 1.23 2008/04/05 12:19:20 fabiankeil
- * Factor compile_host_pattern() out of create_url_spec().
- *
- * Revision 1.22 2008/03/30 15:02:32 fabiankeil
- * SZitify unknown_method().
- *
- * Revision 1.21 2007/12/24 16:34:23 fabiankeil
- * Band-aid (and micro-optimization) that makes it less likely to run out of
- * stack space with overly-complex path patterns. Probably masks the problem
- * reported by Lee in #1856679. Hohoho.
- *
- * Revision 1.20 2007/09/02 15:31:20 fabiankeil
- * Move match_portlist() from filter.c to urlmatch.c.
- * It's used for url matching, not for filtering.
- *
- * Revision 1.19 2007/09/02 13:42:11 fabiankeil
- * - Allow port lists in url patterns.
- * - Ditch unused url_spec member pathlen.
- *
- * Revision 1.18 2007/07/30 16:42:21 fabiankeil
- * Move the method check into unknown_method()
- * and loop through the known methods instead
- * of using a screen-long OR chain.
- *
- * Revision 1.17 2007/04/15 16:39:21 fabiankeil
- * Introduce tags as alternative way to specify which
- * actions apply to a request. At the moment tags can be
- * created based on client and server headers.
- *
- * Revision 1.16 2007/02/13 13:59:24 fabiankeil
- * Remove redundant log message.
- *
- * Revision 1.15 2007/01/28 16:11:23 fabiankeil
- * Accept WebDAV methods for subversion
- * in parse_http_request(). Closes FR 1581425.
- *
- * Revision 1.14 2007/01/06 14:23:56 fabiankeil
- * Fix gcc43 warnings. Mark *csp as immutable
- * for parse_http_url() and url_match().
- * Replace a sprintf call with snprintf.
- *
- * Revision 1.13 2006/12/06 19:50:54 fabiankeil
- * parse_http_url() now handles intercepted
- * HTTP request lines as well. Moved parts
- * of parse_http_url()'s code into
- * init_domain_components() so that it can
- * be reused in chat().
- *
- * Revision 1.12 2006/07/18 14:48:47 david__schmidt
- * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
- * with what was really the latest development (the v_3_0_branch branch)
- *
- * Revision 1.10.2.7 2003/05/17 15:57:24 oes
- * - parse_http_url now checks memory allocation failure for

- * Closes bug #736344
- * - Added a comment to what might look like a bug in
- * create_url_spec (see !bug #736931)
- * - Comment cosmetics
- *
- * Revision 1.10.2.6 2003/05/07 12:39:48 oes
- * Fix typo: Default port for https URLs is 443, not 143.
- * Thanks to Scott Tregear for spotting this one.

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

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

- * - 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 1.11 2001/06/07 23:08:12 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

- *
- * Revision 1.7 2001/05/26 01:26:34 jongfoster
- * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.

- *
- * Revision 1.4 2001/05/22 18:56:28 oes

- * 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.
