38 * Revision 1.22 2007/06/01 18:16:36 fabiankeil
39 * Use the same mutex for gethostbyname() and gethostbyaddr() to prevent
40 * deadlocks and crashes on OpenBSD and possibly other OS with neither
41 * gethostbyname_r() nor gethostaddr_r(). Closes BR#1729174.
42 * Thanks to Ralf Horstmann for report and solution.
44 * Revision 1.21 2007/04/22 13:18:06 fabiankeil
45 * Keep the HTTP snippets local.
47 * Revision 1.20 2006/12/26 17:31:41 fabiankeil
48 * Mutex protect rand() if POSIX threading
49 * is used, warn the user if that's not possible
50 * and stop using it on _WIN32 where it could
53 * Revision 1.19 2006/12/06 19:41:39 fabiankeil
54 * Privoxy is now able to run as intercepting
55 * proxy in combination with any packet filter
56 * that does the port redirection. The destination
57 * is extracted from the "Host:" header which
58 * should be available for nearly all requests.
60 * Moved HTTP snipplets into jcc.c.
61 * Added error message for gopher proxy requests.
63 * Revision 1.18 2006/11/13 19:05:51 fabiankeil
64 * Make pthread mutex locking more generic. Instead of
65 * checking for OSX and OpenBSD, check for FEATURE_PTHREAD
66 * and use mutex locking unless there is an _r function
67 * available. Better safe than sorry.
69 * Fixes "./configure --disable-pthread" and should result
70 * in less threading-related problems on pthread-using platforms,
71 * but it still doesn't fix BR#1122404.
73 * Revision 1.17 2006/11/06 19:58:23 fabiankeil
74 * Move pthread.h inclusion from jcc.c to jcc.h.
75 * Fixes build on x86-freebsd1 (FreeBSD 5.4-RELEASE).
77 * Revision 1.16 2006/09/02 15:36:42 fabiankeil
78 * Follow the OpenBSD port's lead and protect the resolve
79 * functions on OpenBSD as well.
81 * Revision 1.15 2006/09/02 10:24:30 fabiankeil
82 * Include pthread.h for OpenBSD to make Privoxy build again.
84 * Tested shortly on OpenBSD 3.9 without problems, but the OpenBSD
85 * port has additional patches to use the mutexes OSX_DARWIN needs,
86 * and it should be investigated if they are still required for
89 * Revision 1.14 2006/07/18 14:48:46 david__schmidt
90 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
91 * with what was really the latest development (the v_3_0_branch branch)
93 * Revision 1.12.2.3 2006/01/21 16:16:08 david__schmidt
94 * Thanks to Edward Carrel for his patch to modernize OSX's
\rpthreads support. See bug #1409623.
96 * Revision 1.12.2.2 2005/04/03 20:10:50 david__schmidt
97 * Thanks to Jindrich Makovicka for a race condition fix for the log
98 * file. The race condition remains for non-pthread implementations.
99 * Reference patch #1175720.
101 * Revision 1.12.2.1 2003/03/07 03:41:05 david__schmidt
102 * Wrapping all *_r functions (the non-_r versions of them) with mutex
103 * semaphores for OSX. Hopefully this will take care of all of those pesky
106 * Revision 1.12 2002/03/26 22:29:55 swa
107 * we have a new homepage!
109 * Revision 1.11 2002/03/24 13:25:43 swa
110 * name change related issues
112 * Revision 1.10 2002/03/16 23:54:06 jongfoster
113 * Adding graceful termination feature, to help look for memory leaks.
114 * If you enable this (which, by design, has to be done by hand
115 * editing config.h) and then go to http://i.j.b/die, then the program
116 * will exit cleanly after the *next* request. It should free all the
117 * memory that was used.
119 * Revision 1.9 2002/03/07 03:52:44 oes
120 * Set logging to tty for --no-daemon mode
122 * Revision 1.8 2002/03/04 18:19:49 oes
123 * Added extern const char *pidfile
125 * Revision 1.7 2001/11/05 21:41:43 steudten
126 * Add changes to be a real daemon just for unix os.
127 * (change cwd to /, detach from controlling tty, set
128 * process group and session leader to the own process.
130 * Add some fatal-error log message for failed malloc().
131 * Add '-d' if compiled with 'configure --with-debug' to
132 * enable debug output.
134 * Revision 1.6 2001/07/30 22:08:36 jongfoster
135 * Tidying up #defines:
136 * - All feature #defines are now of the form FEATURE_xxx
137 * - Permanently turned off WIN_GUI_EDIT
138 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
140 * Revision 1.5 2001/07/29 19:32:00 jongfoster
141 * Renaming _main() [mingw32 only] to real_main(), for ANSI compliance.
143 * Revision 1.4 2001/07/29 18:58:15 jongfoster
144 * Removing nested #includes, adding forward declarations for needed
145 * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
147 * Revision 1.3 2001/07/18 12:31:58 oes
148 * moved #define freez from jcc.h to project.h
150 * Revision 1.2 2001/05/31 21:24:47 jongfoster
151 * Changed "permission" to "action" throughout.
152 * Removed DEFAULT_USER_AGENT - it must now be specified manually.
153 * Moved vanilla wafer check into chat(), since we must now
154 * decide whether or not to add it based on the URL.
156 * Revision 1.1.1.1 2001/05/15 13:58:56 oes
157 * Initial import of version 2.9.3 source tree
