|
|||
|
|
* Flush work-in-progress changes to keep outgoing connections
|
|||
|
|
* alive where possible. Incomplete and mostly #ifdef'd out.

|

|
|
* Revision 1.24 2008/09/07 12:35:05 fabiankeil
|
|||
|
|
* Add mutex lock support for _WIN32.
|
|||
|
|
*
|
|||
|
|
* Revision 1.23 2008/09/04 08:13:58 fabiankeil
|
|||
|
|
* Prepare for critical sections on Windows by adding a
|
|||
|
|
* layer of indirection before the pthread mutex functions.
|
|||
|
|
*
|
|||
|
|
* Revision 1.22 2007/06/01 18:16:36 fabiankeil
|
|||
|
|
* Use the same mutex for gethostbyname() and gethostbyaddr() to prevent
|
|||
|
|
* deadlocks and crashes on OpenBSD and possibly other OS with neither
|
|||
|
|
* gethostbyname_r() nor gethostaddr_r(). Closes BR#1729174.
|
|||
|
|
* Thanks to Ralf Horstmann for report and solution.
|
|||
|
|
*
|
|||
|
|
* Revision 1.21 2007/04/22 13:18:06 fabiankeil
|
|||
|
|
* Keep the HTTP snippets local.
|

|

|
|
* Revision 1.20 2006/12/26 17:31:41 fabiankeil
|
|||
|
|
* Mutex protect rand() if POSIX threading
|
|||
|
|
* is used, warn the user if that's not possible
|
|||
|
|
* and stop using it on _WIN32 where it could
|
|||
|
|
* cause crashes.
|
|||

|
|||
|
|
* Revision 1.19 2006/12/06 19:41:39 fabiankeil
|
|||
|
|
* Privoxy is now able to run as intercepting
|
|||
|
|
* proxy in combination with any packet filter
|
|||
|
|
* that does the port redirection. The destination
|
|||
|
|
* is extracted from the "Host:" header which
|
|||
|
|
* should be available for nearly all requests.
|
|||
|
|
*
|
|||
|
|
* Moved HTTP snipplets into jcc.c.
|
|||
|
|
* Added error message for gopher proxy requests.
|
|||
|
|
*
|
|||
|
|
* Revision 1.18 2006/11/13 19:05:51 fabiankeil
|
|||
|
|
* Make pthread mutex locking more generic. Instead of
|
|||
|
|
* checking for OSX and OpenBSD, check for FEATURE_PTHREAD
|
|||
|
|
* and use mutex locking unless there is an _r function
|
|||
|
|
* available. Better safe than sorry.
|
|||
|
|
*
|
|||
|
|
* Fixes "./configure --disable-pthread" and should result
|
|||
|
|
* in less threading-related problems on pthread-using platforms,
|
|||
|
|
* but it still doesn't fix BR#1122404.
|
|||
|
|
*
|
|||
|
|
* Revision 1.17 2006/11/06 19:58:23 fabiankeil
|
|||
|
|
* Move pthread.h inclusion from jcc.c to jcc.h.
|
|||
|
|
* Fixes build on x86-freebsd1 (FreeBSD 5.4-RELEASE).
|
|||
|
|
*
|
|||
|
|
* Revision 1.16 2006/09/02 15:36:42 fabiankeil
|
|||
|
|
* Follow the OpenBSD port's lead and protect the resolve
|
|||
|
|
* functions on OpenBSD as well.
|
|||
|
|
*
|
|||
|
|
* Revision 1.15 2006/09/02 10:24:30 fabiankeil
|
|||
|
|
* Include pthread.h for OpenBSD to make Privoxy build again.
|
|||
|
|
*
|
|||
|
|
* Tested shortly on OpenBSD 3.9 without problems, but the OpenBSD
|
|||
|
|
* port has additional patches to use the mutexes OSX_DARWIN needs,
|
|||
|
|
* and it should be investigated if they are still required for
|
|||
|
|
* reliable operation.

|
|
* Revision 1.14 2006/07/18 14:48:46 david__schmidt
|
|||
|
|
* Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
|
|||
|
|
* with what was really the latest development (the v_3_0_branch branch)
|
|||
|
|
*
|
|||
|
|
* Revision 1.12.2.3 2006/01/21 16:16:08 david__schmidt
|
|||
|
|
* Thanks to Edward Carrel for his patch to modernize OSX's
pthreads support. See bug #1409623.
|
|||
|
|
*
|
|||
|
|
* Revision 1.12.2.2 2005/04/03 20:10:50 david__schmidt
|
|||
|
|
* Thanks to Jindrich Makovicka for a race condition fix for the log
|
|||
|
|
* file. The race condition remains for non-pthread implementations.
|
|||
|
|
* Reference patch #1175720.
|
|||
|
|
*
|
|||
|
|
* Revision 1.12.2.1 2003/03/07 03:41:05 david__schmidt
|
|||
|
|
* Wrapping all *_r functions (the non-_r versions of them) with mutex
|
|||
|
|
* semaphores for OSX. Hopefully this will take care of all of those pesky
|
|||
|
|
* crash reports.

* Revision 1.10 2002/03/16 23:54:06 jongfoster
|
|||
|
|
* Adding graceful termination feature, to help look for memory leaks.
|
|||
|
|
* If you enable this (which, by design, has to be done by hand
|
|||
|
|
* editing config.h) and then go to http://i.j.b/die, then the program
|
|||
|
|
* will exit cleanly after the *next* request. It should free all the
|
|||
|
|
* memory that was used.

|
|||
