36 * Revision 1.44 2006/08/18 16:03:16 david__schmidt
37 * Tweak for OS/2 build happiness.
39 * Revision 1.43 2006/08/03 02:46:41 david__schmidt
40 * Incorporate Fabian Keil's patch work:
41 * http://www.fabiankeil.de/sourcecode/privoxy/
43 * Revision 1.42 2006/07/18 14:48:46 david__schmidt
44 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
45 * with what was really the latest development (the v_3_0_branch branch)
47 * Revision 1.40.2.4 2005/04/03 20:10:50 david__schmidt
48 * Thanks to Jindrich Makovicka for a race condition fix for the log
49 * file. The race condition remains for non-pthread implementations.
50 * Reference patch #1175720.
52 * Revision 1.40.2.3 2003/03/07 03:41:04 david__schmidt
53 * Wrapping all *_r functions (the non-_r versions of them) with mutex
54 * semaphores for OSX. Hopefully this will take care of all of those pesky
57 * Revision 1.40.2.2 2002/09/28 00:30:57 david__schmidt
58 * Update error logging to give sane values for thread IDs on Mach kernels.
59 * It's still a hack, but at least it looks farily normal. We print the
60 * absolute value of the first 4 bytes of the pthread_t modded with 1000.
62 * Revision 1.40.2.1 2002/09/25 12:47:42 oes

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