38 * Revision 1.89 2009/03/01 18:46:33 fabiankeil
39 * - Help clang understand that we aren't
40 * dereferencing NULL pointers here.
41 * - Some style fixes in the modified region.
43 * Revision 1.88 2009/02/28 10:57:10 fabiankeil

48 * Revision 1.87 2009/02/15 07:56:13 fabiankeil
49 * Increase default socket timeout to 300 seconds.
51 * Revision 1.86 2009/02/08 19:18:57 fabiankeil
52 * Now that we have the match-all.action file, the other action
53 * files changed their position in config->actions_file[] back
54 * to the way it was before standard.action got removed and the
55 * changes from revision 1.84 have to be reverted.
57 * Revision 1.85 2009/01/22 12:06:26 fabiankeil
58 * Don't keep connections alive when running single-threaded.
60 * Revision 1.84 2009/01/14 16:14:36 fabiankeil

76 * Add new config option: keep-alive-timeout.
78 * Revision 1.80 2008/08/31 15:59:03 fabiankeil
79 * There's no reason to let remote toggling support depend
80 * on FEATURE_CGI_EDIT_ACTIONS, so make sure it doesn't.
82 * Revision 1.79 2008/08/30 12:03:07 fabiankeil
83 * Remove FEATURE_COOKIE_JAR.
85 * Revision 1.78 2008/08/02 08:23:22 fabiankeil

89 * Reported by Pietro Leone.
91 * Revision 1.77 2008/05/26 16:13:22 fabiankeil

130 * #1763173 from Stefan Huehner: declare unload_configfile() static.
132 * Revision 1.65 2007/07/21 11:51:36 fabiankeil
133 * As Hal noticed, checking dispatch_cgi() as the last cruncher
134 * looks like a bug if CGI requests are blocked unintentionally,
135 * so don't do it unless the user enabled the new config option
136 * "allow-cgi-request-crunching".
138 * Revision 1.64 2007/05/21 10:44:08 fabiankeil

143 * - Remove an unnecessary temporary memory allocation.
144 * - Don't log anything to the console when running as
145 * daemon and no errors occurred.
147 * Revision 1.63 2007/04/09 18:11:36 fabiankeil
148 * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
150 * Revision 1.62 2007/03/17 15:20:05 fabiankeil
151 * New config option: enforce-blocks.
153 * Revision 1.61 2007/03/16 16:47:35 fabiankeil
154 * - Mention other reasons why acl directive loading might have failed.
155 * - Don't log the acl source if the acl destination is to blame.
157 * Revision 1.60 2007/01/27 13:09:16 fabiankeil
158 * Add new config option "templdir" to
159 * change the templates directory.
161 * Revision 1.59 2006/12/31 17:56:38 fabiankeil
162 * Added config option accept-intercepted-requests
163 * and disabled it by default.
165 * Revision 1.58 2006/12/31 14:24:29 fabiankeil
166 * Fix gcc43 compiler warnings.

184 * Same limitations as for the action files apply.
187 * Revision 1.53 2006/09/06 18:45:03 fabiankeil
188 * Incorporate modified version of Roland Rosenfeld's patch to
189 * optionally access the user-manual via Privoxy. Closes patch 679075.
191 * Formatting changed to Privoxy style, added call to
192 * cgi_error_no_template if the requested file doesn't
193 * exist and modified check whether or not Privoxy itself
194 * should serve the manual. Should work cross-platform now.
196 * Revision 1.52 2006/09/06 10:43:32 fabiankeil
197 * Added config option enable-remote-http-toggle
198 * to specify if Privoxy should recognize special
199 * headers (currently only X-Filter) to change its

211 * Revision 1.48.2.7 2006/02/02 17:29:16 david__schmidt
212 * Don't forget to malloc space for the null terminator...
214 * Revision 1.48.2.6 2006/01/29 23:10:56 david__schmidt
215 * Multiple filter file support
217 * Revision 1.48.2.5 2003/05/08 15:17:25 oes
218 * Closed two memory leaks; hopefully the last remaining ones
219 * (in the main execution paths, anyway).
221 * Revision 1.48.2.4 2003/04/11 12:06:14 oes
222 * Addressed bug #719435

236 * savearg now uses own linking code instead of (now special-cased) add_help_link
238 * Revision 1.47 2002/05/12 21:36:29 jongfoster
239 * Correcting function comments
241 * Revision 1.46 2002/04/26 12:55:14 oes

265 * name change related issues
267 * Revision 1.38 2002/03/24 13:05:48 jongfoster
268 * Renaming re_filterfile to filterfile
270 * Revision 1.37 2002/03/16 23:54:06 jongfoster
271 * Adding graceful termination feature, to help look for memory leaks.
272 * If you enable this (which, by design, has to be done by hand
273 * editing config.h) and then go to http://i.j.b/die, then the program
274 * will exit cleanly after the *next* request. It should free all the
275 * memory that was used.
277 * Revision 1.36 2002/03/13 00:27:05 jongfoster
280 * Revision 1.35 2002/03/07 03:52:44 oes

296 * Replacing strsav() with string_append()
298 * Revision 1.29 2002/01/17 21:02:30 jongfoster
299 * Moving all our URL and URL pattern parsing code to urlmatch.c.
301 * Renaming free_url to free_url_spec, since it frees a struct url_spec.
303 * Revision 1.28 2001/12/30 14:07:32 steudten
304 * - Add signal handling (unix)
305 * - Add SIGHUP handler (unix)
306 * - Add creation of pidfile (unix)
307 * - Add action 'top' in rc file (RH)
308 * - Add entry 'SIGNALS' to manpage
309 * - Add exit message to logfile (unix)
311 * Revision 1.27 2001/11/07 00:02:13 steudten
312 * Add line number in error output for lineparsing for
313 * actionsfile and configfile.
314 * Special handling for CLF added.
316 * Revision 1.26 2001/11/05 21:41:43 steudten
317 * Add changes to be a real daemon just for unix os.
318 * (change cwd to /, detach from controlling tty, set
319 * process group and session leader to the own process.
321 * Add some fatal-error log message for failed malloc().
322 * Add '-d' if compiled with 'configure --with-debug' to
323 * enable debug output.
325 * Revision 1.25 2001/10/25 03:40:48 david__schmidt
326 * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
327 * threads to call select() simultaneously. So, it's time to do a real, live,
328 * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
329 * (native). Both versions will work, but using __OS2__ offers multi-threading.
331 * Revision 1.24 2001/10/23 21:40:30 jongfoster
332 * Added support for enable-edit-actions and enable-remote-toggle config
335 * Revision 1.23 2001/10/07 15:36:00 oes

341 * Revision 1.21 2001/09/16 17:10:43 jongfoster
342 * Moving function savearg() here, since it was the only thing left in
345 * Revision 1.20 2001/07/30 22:08:36 jongfoster
346 * Tidying up #defines:
347 * - All feature #defines are now of the form FEATURE_xxx
348 * - Permanently turned off WIN_GUI_EDIT
349 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
351 * Revision 1.19 2001/07/15 17:45:16 jongfoster
352 * Removing some unused #includes
354 * Revision 1.18 2001/07/13 14:01:14 oes
355 * - Removed all #ifdef PCRS
356 * - Removed vim-settings
358 * Revision 1.17 2001/06/29 13:31:03 oes
359 * - Improved comments
360 * - Fixed (actionsfile) and sorted hashes
361 * - Introduced admin_address and proxy-info-url
362 * as config parameters
363 * - Renamed config->proxy_args_invocation (which didn't have
364 * the invocation but the options!) to config->proxy_args
365 * - Various adaptions
366 * - Removed logentry from cancelled commit
368 * Revision 1.16 2001/06/09 10:55:28 jongfoster
369 * Changing BUFSIZ ==> BUFFER_SIZE
371 * Revision 1.15 2001/06/07 23:13:40 jongfoster
372 * Merging ACL and forward files into config file.
373 * Cosmetic: Sorting config file options alphabetically.
374 * Cosmetic: Adding brief syntax comments to config file options.
376 * Revision 1.14 2001/06/07 14:46:25 joergs
377 * Missing make_path() added for re_filterfile.
379 * Revision 1.13 2001/06/05 22:33:54 jongfoster
381 * Fixed minor memory leak.
382 * Also now uses make_path to prepend the pathnames.
384 * Revision 1.12 2001/06/05 20:04:09 jongfoster
385 * Now uses _snprintf() in place of snprintf() under Win32.
387 * Revision 1.11 2001/06/04 18:31:58 swa
388 * files are now prefixed with either `confdir' or `logdir'.
389 * `make redhat-dist' replaces both entries confdir and logdir
392 * Revision 1.10 2001/06/03 19:11:54 oes
393 * introduced confdir option
395 * Revision 1.9 2001/06/01 20:06:24 jongfoster
396 * Removed support for "tinygif" option - moved to actions file.
398 * Revision 1.8 2001/05/31 21:27:13 jongfoster
399 * Removed many options from the config file and into the
400 * "actions" file: add_forwarded, suppress_vanilla_wafer,
401 * wafer, add_header, user_agent, referer, from
402 * Also globally replaced "permission" with "action".
404 * Revision 1.7 2001/05/29 09:50:24 jongfoster
405 * Unified blocklist/imagelist/permissionslist.
406 * File format is still under discussion, but the internal changes
409 * Also modified interceptor behaviour:
410 * - We now intercept all URLs beginning with one of the following
411 * prefixes (and *only* these prefixes):
413 * * http://ijbswa.sf.net/config/
414 * * http://ijbswa.sourceforge.net/config/
415 * - New interceptors "home page" - go to http://i.j.b/ to see it.
416 * - Internal changes so that intercepted and fast redirect pages
417 * are not replaced with an image.
418 * - Interceptors now have the option to send a binary page direct
419 * to the client. (i.e. ijb-send-banner uses this)
420 * - Implemented show-url-info interceptor. (Which is why I needed
421 * the above interceptors changes - a typical URL is
422 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
423 * The previous mechanism would not have intercepted that, and
424 * if it had been intercepted then it then it would have replaced
427 * Revision 1.6 2001/05/26 00:28:36 jongfoster
428 * Automatic reloading of config file.
429 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
430 * Most of the global variables have been moved to a new
431 * struct configuration_spec, accessed through csp->config->globalname
432 * Most of the globals remaining are used by the Win32 GUI.
434 * Revision 1.5 2001/05/25 22:34:30 jongfoster
437 * Revision 1.4 2001/05/22 18:46:04 oes
439 * - Enabled filtering banners by size rather than URL
440 * by adding patterns that replace all standard banner
441 * sizes with the "Junkbuster" gif to the re_filterfile
443 * - Enabled filtering WebBugs by providing a pattern
444 * which kills all 1x1 images
446 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
447 * which is selected by the (nonstandard and therefore
448 * capital) letter 'U' in the option string.
449 * It causes the quantifiers to be ungreedy by default.
450 * Appending a ? turns back to greedy (!).
452 * - Added a new interceptor ijb-send-banner, which
453 * sends back the "Junkbuster" gif. Without imagelist or
454 * MSIE detection support, or if tinygif = 1, or the
455 * URL isn't recognized as an imageurl, a lame HTML
456 * explanation is sent instead.
458 * - Added new feature, which permits blocking remote
459 * script redirects and firing back a local redirect
461 * The feature is conditionally compiled, i.e. it
462 * can be disabled with --disable-fast-redirects,
463 * plus it must be activated by a "fast-redirects"
464 * line in the config file, has its own log level
465 * and of course wants to be displayed by show-proxy-args
466 * Note: Boy, all the #ifdefs in 1001 locations and
467 * all the fumbling with configure.in and acconfig.h
468 * were *way* more work than the feature itself :-(
470 * - Because a generic redirect template was needed for
471 * this, tinygif = 3 now uses the same.
473 * - Moved GIFs, and other static HTTP response templates
478 * - Removed some >400 CRs again (Jon, you really worked
481 * Revision 1.3 2001/05/20 01:21:20 jongfoster
482 * Version 2.9.4 checkin.
483 * - Merged popupfile and cookiefile, and added control over PCRS
484 * filtering, in new "permissionsfile".
485 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
486 * file error you now get a message box (in the Win32 GUI) rather
487 * than the program exiting with no explanation.
488 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
490 * - Removed tabs from "config"
