36 * Revision 1.40.2.4 2005/04/03 20:10:50 david__schmidt
37 * Thanks to Jindrich Makovicka for a race condition fix for the log
38 * file. The race condition remains for non-pthread implementations.
39 * Reference patch #1175720.
41 * Revision 1.40.2.3 2003/03/07 03:41:04 david__schmidt
42 * Wrapping all *_r functions (the non-_r versions of them) with mutex
43 * semaphores for OSX. Hopefully this will take care of all of those pesky
46 * Revision 1.40.2.2 2002/09/28 00:30:57 david__schmidt
47 * Update error logging to give sane values for thread IDs on Mach kernels.
48 * It's still a hack, but at least it looks farily normal. We print the
49 * absolute value of the first 4 bytes of the pthread_t modded with 1000.
51 * Revision 1.40.2.1 2002/09/25 12:47:42 oes
52 * Make log_error safe against NULL string arguments
54 * Revision 1.40 2002/05/22 01:27:27 david__schmidt
56 * Add os2_socket_strerr mirroring w32_socket_strerr.
58 * Revision 1.39 2002/04/03 17:15:27 gliptak
59 * zero padding thread ids in log
61 * Revision 1.38 2002/03/31 17:18:59 jongfoster
62 * Win32 only: Enabling STRICT to fix a VC++ compile warning.
64 * Revision 1.37 2002/03/27 14:32:43 david__schmidt
65 * More compiler warning message maintenance
67 * Revision 1.36 2002/03/26 22:29:54 swa
68 * we have a new homepage!
70 * Revision 1.35 2002/03/24 15:23:33 jongfoster
73 * Revision 1.34 2002/03/24 13:25:43 swa
74 * name change related issues
76 * Revision 1.33 2002/03/13 00:27:04 jongfoster
79 * Revision 1.32 2002/03/07 03:46:17 oes
80 * Fixed compiler warnings
82 * Revision 1.31 2002/03/06 23:02:57 jongfoster
85 * Revision 1.30 2002/03/05 22:43:45 david__schmidt
86 * - Better error reporting on OS/2
87 * - Fix double-slash comment (oops)
89 * Revision 1.29 2002/03/04 23:45:13 jongfoster
90 * Printing thread ID if using Win32 native threads
92 * Revision 1.28 2002/03/04 17:59:59 oes
93 * Deleted deletePidFile(), cosmetics
95 * Revision 1.27 2002/03/04 02:08:01 david__schmidt
96 * Enable web editing of actions file on OS/2 (it had been broken all this time!)
98 * Revision 1.26 2002/01/09 19:05:45 steudten
99 * Fix big memory leak.
101 * Revision 1.25 2002/01/09 14:32:08 oes
102 * Added support for gmtime_r and localtime_r.
104 * Revision 1.24 2001/12/30 14:07:32 steudten
105 * - Add signal handling (unix)
106 * - Add SIGHUP handler (unix)
107 * - Add creation of pidfile (unix)
108 * - Add action 'top' in rc file (RH)
109 * - Add entry 'SIGNALS' to manpage
110 * - Add exit message to logfile (unix)
112 * Revision 1.23 2001/11/07 00:02:13 steudten
113 * Add line number in error output for lineparsing for
114 * actionsfile and configfile.
115 * Special handling for CLF added.
117 * Revision 1.22 2001/11/05 23:43:05 steudten
118 * Add time+date to log files.
120 * Revision 1.21 2001/10/25 03:40:47 david__schmidt
121 * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
122 * threads to call select() simultaneously. So, it's time to do a real, live,
123 * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
124 * (native). Both versions will work, but using __OS2__ offers multi-threading.
126 * Revision 1.20 2001/09/16 23:04:34 jongfoster
129 * Revision 1.19 2001/09/13 20:08:06 jongfoster
130 * Adding support for LOG_LEVEL_CGI
132 * Revision 1.18 2001/09/10 11:27:24 oes
133 * Declaration of w32_socket_strerr now conditional
135 * Revision 1.17 2001/09/10 10:17:13 oes
136 * Removed unused variable; Fixed sprintf format
138 * Revision 1.16 2001/07/30 22:08:36 jongfoster
139 * Tidying up #defines:
140 * - All feature #defines are now of the form FEATURE_xxx
141 * - Permanently turned off WIN_GUI_EDIT
142 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
144 * Revision 1.15 2001/07/29 17:41:10 jongfoster
145 * Now prints thread ID for each message (pthreads only)
147 * Revision 1.14 2001/07/19 19:03:48 haroon
148 * - Added case for LOG_LEVEL_POPUPS
150 * Revision 1.13 2001/07/13 13:58:58 oes
151 * - Added case for LOG_LEVEL_DEANIMATE
152 * - Removed all #ifdef PCRS
154 * Revision 1.12 2001/06/09 10:55:28 jongfoster
155 * Changing BUFSIZ ==> BUFFER_SIZE
157 * Revision 1.11 2001/06/01 18:14:49 jongfoster
158 * Changing the calls to strerr() to check HAVE_STRERR (which is defined
159 * in config.h if appropriate) rather than the NO_STRERR macro.
161 * Revision 1.10 2001/05/29 11:52:21 oes

168 * Added support for CLF (Common Log Format) and fixed LOG_LEVEL_LOG
170 * Revision 1.7 2001/05/26 15:21:28 jongfoster
171 * Activity animation in Win32 GUI now works even if debug==0
173 * Revision 1.6 2001/05/25 21:55:08 jongfoster
174 * Now cleans up properly on FATAL (removes taskbar icon etc)
176 * Revision 1.5 2001/05/22 18:46:04 oes
178 * - Enabled filtering banners by size rather than URL
179 * by adding patterns that replace all standard banner
180 * sizes with the "Junkbuster" gif to the re_filterfile
182 * - Enabled filtering WebBugs by providing a pattern
183 * which kills all 1x1 images
185 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
186 * which is selected by the (nonstandard and therefore
187 * capital) letter 'U' in the option string.
188 * It causes the quantifiers to be ungreedy by default.
189 * Appending a ? turns back to greedy (!).
191 * - Added a new interceptor ijb-send-banner, which
192 * sends back the "Junkbuster" gif. Without imagelist or
193 * MSIE detection support, or if tinygif = 1, or the
194 * URL isn't recognized as an imageurl, a lame HTML
195 * explanation is sent instead.
197 * - Added new feature, which permits blocking remote
198 * script redirects and firing back a local redirect
200 * The feature is conditionally compiled, i.e. it
201 * can be disabled with --disable-fast-redirects,
202 * plus it must be activated by a "fast-redirects"
203 * line in the config file, has its own log level
204 * and of course wants to be displayed by show-proxy-args
205 * Note: Boy, all the #ifdefs in 1001 locations and
206 * all the fumbling with configure.in and acconfig.h
207 * were *way* more work than the feature itself :-(
209 * - Because a generic redirect template was needed for
210 * this, tinygif = 3 now uses the same.
212 * - Moved GIFs, and other static HTTP response templates
217 * - Removed some >400 CRs again (Jon, you really worked
220 * Revision 1.4 2001/05/21 19:32:54 jongfoster
221 * Added another #ifdef _WIN_CONSOLE
223 * Revision 1.3 2001/05/20 01:11:40 jongfoster
224 * Added support for LOG_LEVEL_FATAL
225 * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
226 * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
228 * Revision 1.2 2001/05/17 22:42:01 oes
229 * - Cleaned CRLF's from the sources and related files
230 * - Repaired logging for REF and FRC
232 * Revision 1.1.1.1 2001/05/15 13:58:51 oes
233 * Initial import of version 2.9.3 source tree
