38 * Revision 1.90 2009/03/07 17:58:02 fabiankeil
39 * Fix two mingw32-only buffer overflows. Note that triggering
40 * them requires control over the configuration file in which
41 * case all bets are off anyway.
43 * Revision 1.89 2009/03/01 18:46:33 fabiankeil
44 * - Help clang understand that we aren't
45 * dereferencing NULL pointers here.
46 * - Some style fixes in the modified region.
48 * Revision 1.88 2009/02/28 10:57:10 fabiankeil
49 * Gimme a break or two. Don't let the show-status page
50 * link to the website documentation for the user-manual
53 * Revision 1.87 2009/02/15 07:56:13 fabiankeil
54 * Increase default socket timeout to 300 seconds.
56 * Revision 1.86 2009/02/08 19:18:57 fabiankeil
57 * Now that we have the match-all.action file, the other action
58 * files changed their position in config->actions_file[] back
59 * to the way it was before standard.action got removed and the
60 * changes from revision 1.84 have to be reverted.
62 * Revision 1.85 2009/01/22 12:06:26 fabiankeil
63 * Don't keep connections alive when running single-threaded.
65 * Revision 1.84 2009/01/14 16:14:36 fabiankeil
66 * Due to the standard.action file removal, the other action
67 * files changed their position in config->actions_file[].
68 * Update mingw32 kludge accordingly.
70 * Revision 1.83 2008/12/20 14:53:55 fabiankeil
71 * Add config option socket-timeout to control the time
72 * Privoxy waits for data to arrive on a socket. Useful
73 * in case of stale ssh tunnels or when fuzz-testing.
75 * Revision 1.82 2008/11/16 12:43:49 fabiankeil
76 * Turn keep-alive support into a runtime feature
77 * that is disabled by setting keep-alive-timeout
78 * to a negative value.
80 * Revision 1.81 2008/11/13 09:08:42 fabiankeil
81 * Add new config option: keep-alive-timeout.
83 * Revision 1.80 2008/08/31 15:59:03 fabiankeil
84 * There's no reason to let remote toggling support depend
85 * on FEATURE_CGI_EDIT_ACTIONS, so make sure it doesn't.
87 * Revision 1.79 2008/08/30 12:03:07 fabiankeil
88 * Remove FEATURE_COOKIE_JAR.
90 * Revision 1.78 2008/08/02 08:23:22 fabiankeil
91 * If the enforce-blocks directive is used with FEATURE_FORCE_LOAD
92 * disabled, log a message that blocks will always be enforced
93 * instead of complaining about an unrecognized directive.
94 * Reported by Pietro Leone.
96 * Revision 1.77 2008/05/26 16:13:22 fabiankeil
97 * Reuse directive_hash and don't hash the same directive twice.

104 * Rename load_actions_file() and load_re_filterfile()
105 * as they load multiple files "now".
107 * Revision 1.74 2008/03/26 18:07:07 fabiankeil
108 * Add hostname directive. Closes PR#1918189.
110 * Revision 1.73 2008/02/16 16:54:51 fabiankeil
113 * Revision 1.72 2008/02/03 13:46:15 fabiankeil

116 * Revision 1.71 2007/12/23 15:24:56 fabiankeil
117 * Reword "unrecognized directive" warning, use better
118 * mark up and add a <br>. Fixes parts of #1856559.
120 * Revision 1.70 2007/12/15 14:24:05 fabiankeil
121 * Plug memory leak if listen-address only specifies the port.
123 * Revision 1.69 2007/10/27 13:02:27 fabiankeil
124 * Relocate daemon-mode-related log messages to make sure
125 * they aren't shown again in case of configuration reloads.
127 * Revision 1.68 2007/10/19 16:32:34 fabiankeil
128 * Plug memory leak introduced with my last commit.
130 * Revision 1.67 2007/10/14 14:12:41 fabiankeil
131 * When in daemon mode, close stderr after the configuration file has been
132 * parsed the first time. If logfile isn't set, stop logging. Fixes BR#897436.
134 * Revision 1.66 2007/08/05 14:02:09 fabiankeil
135 * #1763173 from Stefan Huehner: declare unload_configfile() static.
137 * Revision 1.65 2007/07/21 11:51:36 fabiankeil
138 * As Hal noticed, checking dispatch_cgi() as the last cruncher
139 * looks like a bug if CGI requests are blocked unintentionally,
140 * so don't do it unless the user enabled the new config option
141 * "allow-cgi-request-crunching".
143 * Revision 1.64 2007/05/21 10:44:08 fabiankeil
144 * - Use strlcpy() instead of strcpy().
145 * - Stop treating actions files special. Expect a complete file name
146 * (with or without path) like it's done for the rest of the files.
148 * - Remove an unnecessary temporary memory allocation.
149 * - Don't log anything to the console when running as
150 * daemon and no errors occurred.
152 * Revision 1.63 2007/04/09 18:11:36 fabiankeil
153 * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
155 * Revision 1.62 2007/03/17 15:20:05 fabiankeil
156 * New config option: enforce-blocks.
158 * Revision 1.61 2007/03/16 16:47:35 fabiankeil
159 * - Mention other reasons why acl directive loading might have failed.
160 * - Don't log the acl source if the acl destination is to blame.
162 * Revision 1.60 2007/01/27 13:09:16 fabiankeil
163 * Add new config option "templdir" to
164 * change the templates directory.
166 * Revision 1.59 2006/12/31 17:56:38 fabiankeil
167 * Added config option accept-intercepted-requests
168 * and disabled it by default.
170 * Revision 1.58 2006/12/31 14:24:29 fabiankeil
171 * Fix gcc43 compiler warnings.
173 * Revision 1.57 2006/12/21 12:57:48 fabiankeil

186 * Revision 1.54 2006/10/21 16:04:22 fabiankeil
187 * Modified kludge for win32 to make ming32 menu
188 * "Options/Edit Filters" (sort of) work again.
189 * Same limitations as for the action files apply.
192 * Revision 1.53 2006/09/06 18:45:03 fabiankeil
193 * Incorporate modified version of Roland Rosenfeld's patch to
194 * optionally access the user-manual via Privoxy. Closes patch 679075.
196 * Formatting changed to Privoxy style, added call to
197 * cgi_error_no_template if the requested file doesn't
198 * exist and modified check whether or not Privoxy itself
199 * should serve the manual. Should work cross-platform now.
201 * Revision 1.52 2006/09/06 10:43:32 fabiankeil
202 * Added config option enable-remote-http-toggle
203 * to specify if Privoxy should recognize special
204 * headers (currently only X-Filter) to change its
205 * behaviour. Disabled by default.
207 * Revision 1.51 2006/09/06 09:23:37 fabiankeil
208 * Make number of retries in case of forwarded-connect problems
209 * a config file option (forwarded-connect-retries) and use 0 as
212 * Revision 1.50 2006/07/18 14:48:46 david__schmidt
213 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
214 * with what was really the latest development (the v_3_0_branch branch)
216 * Revision 1.48.2.7 2006/02/02 17:29:16 david__schmidt
217 * Don't forget to malloc space for the null terminator...
219 * Revision 1.48.2.6 2006/01/29 23:10:56 david__schmidt
220 * Multiple filter file support
222 * Revision 1.48.2.5 2003/05/08 15:17:25 oes
223 * Closed two memory leaks; hopefully the last remaining ones
224 * (in the main execution paths, anyway).
226 * Revision 1.48.2.4 2003/04/11 12:06:14 oes
227 * Addressed bug #719435
228 * - Extraneous filterfile directives now logged as errors

241 * savearg now uses own linking code instead of (now special-cased) add_help_link
243 * Revision 1.47 2002/05/12 21:36:29 jongfoster
244 * Correcting function comments
246 * Revision 1.46 2002/04/26 12:55:14 oes
247 * - New option "user-manual", defaults to our site
248 * via project.h #define
249 * - savearg now embeds option names in help links

270 * name change related issues
272 * Revision 1.38 2002/03/24 13:05:48 jongfoster
273 * Renaming re_filterfile to filterfile
275 * Revision 1.37 2002/03/16 23:54:06 jongfoster
276 * Adding graceful termination feature, to help look for memory leaks.
277 * If you enable this (which, by design, has to be done by hand
278 * editing config.h) and then go to http://i.j.b/die, then the program
279 * will exit cleanly after the *next* request. It should free all the
280 * memory that was used.
282 * Revision 1.36 2002/03/13 00:27:05 jongfoster
285 * Revision 1.35 2002/03/07 03:52:44 oes
286 * Set logging to tty for --no-daemon mode
288 * Revision 1.34 2002/03/06 23:14:35 jongfoster

300 * Revision 1.30 2002/01/22 23:31:43 jongfoster
301 * Replacing strsav() with string_append()
303 * Revision 1.29 2002/01/17 21:02:30 jongfoster
304 * Moving all our URL and URL pattern parsing code to urlmatch.c.
306 * Renaming free_url to free_url_spec, since it frees a struct url_spec.
308 * Revision 1.28 2001/12/30 14:07:32 steudten
309 * - Add signal handling (unix)
310 * - Add SIGHUP handler (unix)
311 * - Add creation of pidfile (unix)
312 * - Add action 'top' in rc file (RH)
313 * - Add entry 'SIGNALS' to manpage
314 * - Add exit message to logfile (unix)
316 * Revision 1.27 2001/11/07 00:02:13 steudten
317 * Add line number in error output for lineparsing for
318 * actionsfile and configfile.
319 * Special handling for CLF added.
321 * Revision 1.26 2001/11/05 21:41:43 steudten
322 * Add changes to be a real daemon just for unix os.
323 * (change cwd to /, detach from controlling tty, set
324 * process group and session leader to the own process.
326 * Add some fatal-error log message for failed malloc().
327 * Add '-d' if compiled with 'configure --with-debug' to
328 * enable debug output.
330 * Revision 1.25 2001/10/25 03:40:48 david__schmidt
331 * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
332 * threads to call select() simultaneously. So, it's time to do a real, live,
333 * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
334 * (native). Both versions will work, but using __OS2__ offers multi-threading.
336 * Revision 1.24 2001/10/23 21:40:30 jongfoster
337 * Added support for enable-edit-actions and enable-remote-toggle config
340 * Revision 1.23 2001/10/07 15:36:00 oes

350 * Revision 1.20 2001/07/30 22:08:36 jongfoster
351 * Tidying up #defines:
352 * - All feature #defines are now of the form FEATURE_xxx
353 * - Permanently turned off WIN_GUI_EDIT
354 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
356 * Revision 1.19 2001/07/15 17:45:16 jongfoster
357 * Removing some unused #includes
359 * Revision 1.18 2001/07/13 14:01:14 oes
360 * - Removed all #ifdef PCRS
361 * - Removed vim-settings
363 * Revision 1.17 2001/06/29 13:31:03 oes
364 * - Improved comments
365 * - Fixed (actionsfile) and sorted hashes
366 * - Introduced admin_address and proxy-info-url
367 * as config parameters
368 * - Renamed config->proxy_args_invocation (which didn't have
369 * the invocation but the options!) to config->proxy_args
370 * - Various adaptions
371 * - Removed logentry from cancelled commit
373 * Revision 1.16 2001/06/09 10:55:28 jongfoster

376 * Revision 1.15 2001/06/07 23:13:40 jongfoster
377 * Merging ACL and forward files into config file.
378 * Cosmetic: Sorting config file options alphabetically.
379 * Cosmetic: Adding brief syntax comments to config file options.
381 * Revision 1.14 2001/06/07 14:46:25 joergs
382 * Missing make_path() added for re_filterfile.
384 * Revision 1.13 2001/06/05 22:33:54 jongfoster
386 * Fixed minor memory leak.
387 * Also now uses make_path to prepend the pathnames.
389 * Revision 1.12 2001/06/05 20:04:09 jongfoster
390 * Now uses _snprintf() in place of snprintf() under Win32.
392 * Revision 1.11 2001/06/04 18:31:58 swa
393 * files are now prefixed with either `confdir' or `logdir'.
394 * `make redhat-dist' replaces both entries confdir and logdir
397 * Revision 1.10 2001/06/03 19:11:54 oes
398 * introduced confdir option
400 * Revision 1.9 2001/06/01 20:06:24 jongfoster
401 * Removed support for "tinygif" option - moved to actions file.
403 * Revision 1.8 2001/05/31 21:27:13 jongfoster
404 * Removed many options from the config file and into the
405 * "actions" file: add_forwarded, suppress_vanilla_wafer,
406 * wafer, add_header, user_agent, referer, from
407 * Also globally replaced "permission" with "action".
409 * Revision 1.7 2001/05/29 09:50:24 jongfoster
410 * Unified blocklist/imagelist/permissionslist.
411 * File format is still under discussion, but the internal changes
414 * Also modified interceptor behaviour:
415 * - We now intercept all URLs beginning with one of the following
416 * prefixes (and *only* these prefixes):
418 * * http://ijbswa.sf.net/config/
419 * * http://ijbswa.sourceforge.net/config/
420 * - New interceptors "home page" - go to http://i.j.b/ to see it.
421 * - Internal changes so that intercepted and fast redirect pages
422 * are not replaced with an image.
423 * - Interceptors now have the option to send a binary page direct
424 * to the client. (i.e. ijb-send-banner uses this)
425 * - Implemented show-url-info interceptor. (Which is why I needed
426 * the above interceptors changes - a typical URL is
427 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
428 * The previous mechanism would not have intercepted that, and
429 * if it had been intercepted then it then it would have replaced
432 * Revision 1.6 2001/05/26 00:28:36 jongfoster
433 * Automatic reloading of config file.
434 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
435 * Most of the global variables have been moved to a new
436 * struct configuration_spec, accessed through csp->config->globalname
437 * Most of the globals remaining are used by the Win32 GUI.
439 * Revision 1.5 2001/05/25 22:34:30 jongfoster
442 * Revision 1.4 2001/05/22 18:46:04 oes
444 * - Enabled filtering banners by size rather than URL
445 * by adding patterns that replace all standard banner
446 * sizes with the "Junkbuster" gif to the re_filterfile
448 * - Enabled filtering WebBugs by providing a pattern
449 * which kills all 1x1 images
451 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
452 * which is selected by the (nonstandard and therefore
453 * capital) letter 'U' in the option string.
454 * It causes the quantifiers to be ungreedy by default.
455 * Appending a ? turns back to greedy (!).
457 * - Added a new interceptor ijb-send-banner, which
458 * sends back the "Junkbuster" gif. Without imagelist or
459 * MSIE detection support, or if tinygif = 1, or the
460 * URL isn't recognized as an imageurl, a lame HTML
461 * explanation is sent instead.
463 * - Added new feature, which permits blocking remote
464 * script redirects and firing back a local redirect
466 * The feature is conditionally compiled, i.e. it
467 * can be disabled with --disable-fast-redirects,
468 * plus it must be activated by a "fast-redirects"
469 * line in the config file, has its own log level
470 * and of course wants to be displayed by show-proxy-args
471 * Note: Boy, all the #ifdefs in 1001 locations and
472 * all the fumbling with configure.in and acconfig.h
473 * were *way* more work than the feature itself :-(
475 * - Because a generic redirect template was needed for
476 * this, tinygif = 3 now uses the same.
478 * - Moved GIFs, and other static HTTP response templates
483 * - Removed some >400 CRs again (Jon, you really worked
486 * Revision 1.3 2001/05/20 01:21:20 jongfoster
487 * Version 2.9.4 checkin.
488 * - Merged popupfile and cookiefile, and added control over PCRS
489 * filtering, in new "permissionsfile".
490 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
