36 * Revision 1.40.2.2 2002/09/28 00:30:57 david__schmidt
37 * Update error logging to give sane values for thread IDs on Mach kernels.
38 * It's still a hack, but at least it looks farily normal. We print the
39 * absolute value of the first 4 bytes of the pthread_t modded with 1000.

46 * Add os2_socket_strerr mirroring w32_socket_strerr.
48 * Revision 1.39 2002/04/03 17:15:27 gliptak
49 * zero padding thread ids in log
51 * Revision 1.38 2002/03/31 17:18:59 jongfoster
52 * Win32 only: Enabling STRICT to fix a VC++ compile warning.
54 * Revision 1.37 2002/03/27 14:32:43 david__schmidt
55 * More compiler warning message maintenance
57 * Revision 1.36 2002/03/26 22:29:54 swa
58 * we have a new homepage!
60 * Revision 1.35 2002/03/24 15:23:33 jongfoster
63 * Revision 1.34 2002/03/24 13:25:43 swa
64 * name change related issues
66 * Revision 1.33 2002/03/13 00:27:04 jongfoster
69 * Revision 1.32 2002/03/07 03:46:17 oes
70 * Fixed compiler warnings
72 * Revision 1.31 2002/03/06 23:02:57 jongfoster
75 * Revision 1.30 2002/03/05 22:43:45 david__schmidt
76 * - Better error reporting on OS/2
77 * - Fix double-slash comment (oops)
79 * Revision 1.29 2002/03/04 23:45:13 jongfoster
80 * Printing thread ID if using Win32 native threads
82 * Revision 1.28 2002/03/04 17:59:59 oes
83 * Deleted deletePidFile(), cosmetics
85 * Revision 1.27 2002/03/04 02:08:01 david__schmidt
86 * Enable web editing of actions file on OS/2 (it had been broken all this time!)
88 * Revision 1.26 2002/01/09 19:05:45 steudten
89 * Fix big memory leak.
91 * Revision 1.25 2002/01/09 14:32:08 oes
92 * Added support for gmtime_r and localtime_r.
94 * Revision 1.24 2001/12/30 14:07:32 steudten
95 * - Add signal handling (unix)
96 * - Add SIGHUP handler (unix)
97 * - Add creation of pidfile (unix)
98 * - Add action 'top' in rc file (RH)
99 * - Add entry 'SIGNALS' to manpage
100 * - Add exit message to logfile (unix)
102 * Revision 1.23 2001/11/07 00:02:13 steudten
103 * Add line number in error output for lineparsing for
104 * actionsfile and configfile.
105 * Special handling for CLF added.
107 * Revision 1.22 2001/11/05 23:43:05 steudten
108 * Add time+date to log files.
110 * Revision 1.21 2001/10/25 03:40:47 david__schmidt
111 * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
112 * threads to call select() simultaneously. So, it's time to do a real, live,
113 * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
114 * (native). Both versions will work, but using __OS2__ offers multi-threading.
116 * Revision 1.20 2001/09/16 23:04:34 jongfoster
119 * Revision 1.19 2001/09/13 20:08:06 jongfoster

126 * Removed unused variable; Fixed sprintf format
128 * Revision 1.16 2001/07/30 22:08:36 jongfoster
129 * Tidying up #defines:
130 * - All feature #defines are now of the form FEATURE_xxx
131 * - Permanently turned off WIN_GUI_EDIT
132 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
134 * Revision 1.15 2001/07/29 17:41:10 jongfoster
135 * Now prints thread ID for each message (pthreads only)
137 * Revision 1.14 2001/07/19 19:03:48 haroon
138 * - Added case for LOG_LEVEL_POPUPS
140 * Revision 1.13 2001/07/13 13:58:58 oes
141 * - Added case for LOG_LEVEL_DEANIMATE
142 * - Removed all #ifdef PCRS
144 * Revision 1.12 2001/06/09 10:55:28 jongfoster

147 * Revision 1.11 2001/06/01 18:14:49 jongfoster
148 * Changing the calls to strerr() to check HAVE_STRERR (which is defined

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