36 * Revision 1.43 2006/08/03 02:46:41 david__schmidt
37 * Incorporate Fabian Keil's patch work:
38 * http://www.fabiankeil.de/sourcecode/privoxy/
40 * Revision 1.42 2006/07/18 14:48:46 david__schmidt
41 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
42 * with what was really the latest development (the v_3_0_branch branch)
44 * Revision 1.40.2.4 2005/04/03 20:10:50 david__schmidt
45 * Thanks to Jindrich Makovicka for a race condition fix for the log
46 * file. The race condition remains for non-pthread implementations.
47 * Reference patch #1175720.
49 * Revision 1.40.2.3 2003/03/07 03:41:04 david__schmidt
50 * Wrapping all *_r functions (the non-_r versions of them) with mutex
51 * semaphores for OSX. Hopefully this will take care of all of those pesky
54 * Revision 1.40.2.2 2002/09/28 00:30:57 david__schmidt
55 * Update error logging to give sane values for thread IDs on Mach kernels.
56 * It's still a hack, but at least it looks farily normal. We print the
57 * absolute value of the first 4 bytes of the pthread_t modded with 1000.
59 * Revision 1.40.2.1 2002/09/25 12:47:42 oes

62 * Revision 1.40 2002/05/22 01:27:27 david__schmidt
64 * Add os2_socket_strerr mirroring w32_socket_strerr.
66 * Revision 1.39 2002/04/03 17:15:27 gliptak
67 * zero padding thread ids in log
69 * Revision 1.38 2002/03/31 17:18:59 jongfoster
70 * Win32 only: Enabling STRICT to fix a VC++ compile warning.
72 * Revision 1.37 2002/03/27 14:32:43 david__schmidt
73 * More compiler warning message maintenance
75 * Revision 1.36 2002/03/26 22:29:54 swa
76 * we have a new homepage!
78 * Revision 1.35 2002/03/24 15:23:33 jongfoster
81 * Revision 1.34 2002/03/24 13:25:43 swa
82 * name change related issues
84 * Revision 1.33 2002/03/13 00:27:04 jongfoster
87 * Revision 1.32 2002/03/07 03:46:17 oes
88 * Fixed compiler warnings
90 * Revision 1.31 2002/03/06 23:02:57 jongfoster
93 * Revision 1.30 2002/03/05 22:43:45 david__schmidt
94 * - Better error reporting on OS/2
95 * - Fix double-slash comment (oops)
97 * Revision 1.29 2002/03/04 23:45:13 jongfoster
98 * Printing thread ID if using Win32 native threads
100 * Revision 1.28 2002/03/04 17:59:59 oes
101 * Deleted deletePidFile(), cosmetics
103 * Revision 1.27 2002/03/04 02:08:01 david__schmidt
104 * Enable web editing of actions file on OS/2 (it had been broken all this time!)
106 * Revision 1.26 2002/01/09 19:05:45 steudten
107 * Fix big memory leak.
109 * Revision 1.25 2002/01/09 14:32:08 oes
110 * Added support for gmtime_r and localtime_r.
112 * Revision 1.24 2001/12/30 14:07:32 steudten
113 * - Add signal handling (unix)
114 * - Add SIGHUP handler (unix)
115 * - Add creation of pidfile (unix)
116 * - Add action 'top' in rc file (RH)
117 * - Add entry 'SIGNALS' to manpage
118 * - Add exit message to logfile (unix)
120 * Revision 1.23 2001/11/07 00:02:13 steudten
121 * Add line number in error output for lineparsing for
122 * actionsfile and configfile.
123 * Special handling for CLF added.
125 * Revision 1.22 2001/11/05 23:43:05 steudten
126 * Add time+date to log files.
128 * Revision 1.21 2001/10/25 03:40:47 david__schmidt
129 * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
130 * threads to call select() simultaneously. So, it's time to do a real, live,
131 * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
132 * (native). Both versions will work, but using __OS2__ offers multi-threading.
134 * Revision 1.20 2001/09/16 23:04:34 jongfoster
137 * Revision 1.19 2001/09/13 20:08:06 jongfoster
138 * Adding support for LOG_LEVEL_CGI
140 * Revision 1.18 2001/09/10 11:27:24 oes
141 * Declaration of w32_socket_strerr now conditional
143 * Revision 1.17 2001/09/10 10:17:13 oes
144 * Removed unused variable; Fixed sprintf format
146 * Revision 1.16 2001/07/30 22:08:36 jongfoster
147 * Tidying up #defines:
148 * - All feature #defines are now of the form FEATURE_xxx
149 * - Permanently turned off WIN_GUI_EDIT
150 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
152 * Revision 1.15 2001/07/29 17:41:10 jongfoster
153 * Now prints thread ID for each message (pthreads only)
155 * Revision 1.14 2001/07/19 19:03:48 haroon
156 * - Added case for LOG_LEVEL_POPUPS
158 * Revision 1.13 2001/07/13 13:58:58 oes
159 * - Added case for LOG_LEVEL_DEANIMATE
160 * - Removed all #ifdef PCRS
162 * Revision 1.12 2001/06/09 10:55:28 jongfoster
163 * Changing BUFSIZ ==> BUFFER_SIZE
165 * Revision 1.11 2001/06/01 18:14:49 jongfoster
166 * Changing the calls to strerr() to check HAVE_STRERR (which is defined
167 * in config.h if appropriate) rather than the NO_STRERR macro.
169 * Revision 1.10 2001/05/29 11:52:21 oes
170 * Conditional compilation of w32_socket_error
172 * Revision 1.9 2001/05/28 16:15:17 jongfoster
173 * Improved reporting of errors under Win32.
175 * Revision 1.8 2001/05/26 17:25:14 jongfoster
176 * Added support for CLF (Common Log Format) and fixed LOG_LEVEL_LOG
178 * Revision 1.7 2001/05/26 15:21:28 jongfoster
179 * Activity animation in Win32 GUI now works even if debug==0
181 * Revision 1.6 2001/05/25 21:55:08 jongfoster
182 * Now cleans up properly on FATAL (removes taskbar icon etc)
184 * Revision 1.5 2001/05/22 18:46:04 oes
186 * - Enabled filtering banners by size rather than URL
187 * by adding patterns that replace all standard banner
188 * sizes with the "Junkbuster" gif to the re_filterfile
190 * - Enabled filtering WebBugs by providing a pattern
191 * which kills all 1x1 images
193 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
194 * which is selected by the (nonstandard and therefore
195 * capital) letter 'U' in the option string.
196 * It causes the quantifiers to be ungreedy by default.
197 * Appending a ? turns back to greedy (!).
199 * - Added a new interceptor ijb-send-banner, which
200 * sends back the "Junkbuster" gif. Without imagelist or
201 * MSIE detection support, or if tinygif = 1, or the
202 * URL isn't recognized as an imageurl, a lame HTML
203 * explanation is sent instead.
205 * - Added new feature, which permits blocking remote
206 * script redirects and firing back a local redirect
208 * The feature is conditionally compiled, i.e. it
209 * can be disabled with --disable-fast-redirects,
210 * plus it must be activated by a "fast-redirects"
211 * line in the config file, has its own log level
212 * and of course wants to be displayed by show-proxy-args
213 * Note: Boy, all the #ifdefs in 1001 locations and
214 * all the fumbling with configure.in and acconfig.h
215 * were *way* more work than the feature itself :-(
217 * - Because a generic redirect template was needed for
218 * this, tinygif = 3 now uses the same.
220 * - Moved GIFs, and other static HTTP response templates
225 * - Removed some >400 CRs again (Jon, you really worked
228 * Revision 1.4 2001/05/21 19:32:54 jongfoster
229 * Added another #ifdef _WIN_CONSOLE
231 * Revision 1.3 2001/05/20 01:11:40 jongfoster
232 * Added support for LOG_LEVEL_FATAL
233 * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
234 * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
236 * Revision 1.2 2001/05/17 22:42:01 oes
237 * - Cleaned CRLF's from the sources and related files
238 * - Repaired logging for REF and FRC
240 * Revision 1.1.1.1 2001/05/15 13:58:51 oes
241 * Initial import of version 2.9.3 source tree
