Revision history for Perl extension SpeedyCGI.

2.22	Sat Oct 11 20:34:15 PDT 2003

	- Redhat9 fixes.

	- Better support for setuid under Solaris.

	- Fixes for HP-UX 11.22

	- Fix for memory leak in speedy_backend reported by James H. Thompson

	- speedy_file.c fixes for bugs reported by Dmitri Tikhonov

	- Fix from Lars Thegler for buffer overrun in speedy_opt.c

	- Add efence malloc debugging.

2.21	Thu Sep 26 15:27:35 PDT 2002

	- Fix too many backends problem reported by Theo Petersen.  The
	  problem is due to temp-file corruption that occurs when the
	  web-server sends a TERM signal to the frontend while it is working
	  on the temp file.  It also results in some backends failing due
	  to the corruption.  Added a fix so that signals are always blocked
	  while working on the temp file.

	- Shutdown handler should be called after script is touched.

	- Fixes for Mac OS X 10.1.  Workaround the sigpending() bug,
	  and add msync() which appears to fix a shared-memory flushing
	  problem when temp-file is expanded.

2.20	Wed Sep 11 19:33:36 PDT 2002

	- Added a mod_speedycgi module that works under Apache 2.0.39 or
	  later.  Works with the default prefork mpm, but not with threaded
	  mpm's.

	- Exit status is now passed from the backend to the frontend.
	  The frontend now exits soon after the backend exits instead of
	  when all sockets close.

	- Fixed bug where alarm's were unusable from within perl code.

	- Signal handling in the backend has been cleaned up.  Signal
	  settings will no longer be altered between perl runs.

	- Find scripts by dev/ino/group-name instead of by dev/ino

	- In the "speedy" executable buffering has been changed so
	  that BufsizGet and BufsizPut are now maximum values instead of
	  absolute values.  The buffers will start small and grow
	  to this value if needed.  The default values for these options
	  have been increased.

	- Backend allocation is now controlled better.  Another backend isn't
	  allocated until the previous backend has had a chance to start.
	  This should reduce the tendency to use too many backends when the
	  load fluctuates.
	
	- Initially compiled perl-code is now shared among interpreters
	  within the same group (or same script if not using groups).
	  
	- To implement the new shared perl code and exit status features,
	  an extra parent process is created for each group (or for each
	  script, if not using groups).  This process should use very little
	  cpu or un-shared memory.

	- New code provides doubly linked lists for all slots in the
	  temp file.  This eliminates some of the more obscure linked list
	  code in various places, and enables some minor performance
	  improvements.

2.11	Tue Mar 20 22:59:36 PST 2001

	- When using the new Group option, exit was causing the whole
	  interpreter to exit.
	- Fixed a bug introduced in 2.10 where mod_speedycgi could run
	  the wrong script
	- Fixed a bug where mod_speedycgi could mix up the sh-bang options 
	  between different scripts.
	- Added automated mod_speedycgi testing.
	- Added a workaround for a Solaris 2.5.1 bug that was causing the
	  mungefds and touch tests to fail.
