1	Revision history for Perl extension Coro.	1	Revision history for Perl extension Coro.
2		2
3	3.0	3	TODO: localise SIG{__DIE__} and/or __WARN__
		4	TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
		5	TODO: maybe implement a default message channel, very much like Erlang
		6	(which is cool in a lot of important aspects (failures!),
		7	but very lacking in others (higher level ipc)).
		8
		9	- incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
		10	be local to each coro (see Coro::State).
		11	- possibly bring back 5.10 compatibility (untested).
		12	- work around stupid (and wrong) warning on 5.10 :(.
		13	- overlay the saved state over the context stack. This saves
		14	a few hundred bytes per coroutine on average and also
		15	speeds up context switching a bit.
		16	- (more) correctly calculate stack usage in coro_rss.
		17
		18	4.03 Sat Oct 6 21:24:00 CEST 2007
		19	- added Coro::throw method.
		20	- minor code cleanups.
		21
		22	4.02 Sat Oct 6 02:36:47 CEST 2007
		23	- fix a very minor per-coroutine memleak (a single codereference).
		24	- fixed a bug where the currently in-use c context would be freed
		25	prematurely (can happen only when programs change the stacksize
		26	or use tracing).
		27	- tracing can no longer keep a coro alive after it terminated.
		28	- do static branch prediction in the common path for gcc. gives
		29	about 2-5% speed improvement here.
		30
		31	4.01 Fri Oct 5 22:10:49 CEST 2007
		32	- instead of recreating a standard output handle we simply
		33	use STDOUT, which is faster and hopefully more robust.
		34
		35	4.0 Fri Oct 5 12:56:00 CEST 2007
		36	- incompatibly changed Coro::Storable::freeze.
		37	- major new feature: added Coro::Debug, for interactive coroutine
		38	debugging, tracing and much more.
		39	- major bug fix: unbelievable, but true: $_, $/ and many other
		40	"saved" variables actually weren't being saved. This has been fixed,
		41	of course, while increasing performance while losing all the save
		42	flags.
		43	- save flags are gone, and all the api functions dealing with them.
		44	- added Coro::Semaphore::adjust.
		45	- added Coro::Util::fork_eval.
		46	- added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
		47	- added Coro::killall.
		48	- reduce initial stack sizes to allow for "micro-coroutines".
		49	- better async_pool resource management, moved parts of async_pool
		50	handling to XS (major speed improvement).
		51	- actually croak before modifying important data structures.
		52	- refuse to transfer while compiling.
		53	- possibly support eval EXPR better now.
		54	- enable assembly per default on linux+bsd x86+amd64.
		55	- all internal members were renamed _something for easier subclassing.
		56	- many minor tweaks.
		57
		58	3.63 Wed May 16 14:10:06 CEST 2007
		59	- implement handcoded assembly for x86/amd64 SVR ABI.
		60
		61	3.62 Fri Apr 27 21:36:06 CEST 2007
		62	- upgrade libcoro (which might set unwind info correctly).
		63	- change default on linux to setjmp/longjmp.
		64
		65	3.61 Thu Apr 19 12:36:18 CEST 2007
		66	- Coro::Storable caused an endless loop when thawing invalid
		67	pst's sometimes.
		68	- use a Semaphore in Coro::Storable, as Storable doesn't
		69	seem to be reentrant (although it is documented to
		70	be threadsafe...).
		71	- fix Coro::Signal to bring back the original unreliable
		72	but stateful semantics.
		73	- fixed a lot of typos in Coro.pm (patch submitted by David
		74	Steinbrunner, which applied flawlessly).
		75
		76	3.6 Sat Apr 14 17:13:31 CEST 2007
		77	- added some bugfixes to get eg/myhttpd working again.
		78	- added Coro::Storable for often-cede'ing freeze/thaw.
		79	- try to do a clean exit when a coroutine calls exit
		80	(EXPERIMENTAL).
		81	- got rid of indirect call through _coro_init.
		82	- updated the partly antique examples in eg/ to
		83	work again and be a bit less magic, too.
		84	- fixed Coro::Signal semantics to work as documented again.
		85
		86	3.55 Sun Mar 25 01:20:47 CET 2007
		87	- add SAVE_DEFFH to save the default filehandle and enable
		88	it by default.
		89	- finally move socket-operations from Coro::Socket to Coro::Handle
		90	to be able to unblock foreign sockets.
		91	- add Coro::State::save_also and guarded_save.
		92	- add count accessor to Coro::Semaphore.
		93	- add Coro::State::cctx_stacksize.
		94	- just for the fun of it, do not rely on implicit context,
		95	which can dramatically improve performance, but people
		96	using windows-process-emulation perls do not care much about
		97	performance.
		98
		99	3.51 Sun Mar 4 14:18:04 CET 2007
		100	- fixed a problem when you weakened references to Coro::State's
		101	(patch by Yuval Kogman).
		102
		103	3.501 Wed Feb 28 12:44:07 CET 2007
		104	- rename some global symbols as macosx from hell redefines
		105	them without asking.
		106
		107	3.5 Tue Feb 13 20:22:53 CET 2007
		108	- do AnyEvent model detection earlier, avoiding problems
		109	caused by first using AnyEvent and later Coro::Event.
		110	- implement and document Coro::Event event objects.
		111	- fix a potential problem in Coro::Event causing crashes.
		112	- initialise PL_comppad when creating a new coroutine,
		113	avoids crashes on early coro destruction.
		114
		115	3.41 Mon Jan 22 19:19:49 CET 2007
		116	- readline on Coro::Handle did not support undefined $/,
		117	nor did it deliver partial lines on EOF or error.
		118	- implement malloc fallback for stack allocation because
		119	stupid broken idiotic OSX has a stupid broken
		120	idiotic fits-the-whole-os mmap "implementation" and
		121	my dick feels longer if Coro is portable even to
		122	obsolete platforms.
		123
		124	3.4 Fri Jan 19 21:52:54 CET 2007
		125	- remove t/09_timer.t, as it isn't really testing much
		126	but was rather flaky in practise.
		127	- async_pool coro would keep arguments and callback alive until
		128	it was reused.
		129	- cancellation of a coroutine could cause spurious idle calls
		130	in cede_notself.
		131
		132	3.3 Sat Jan 6 03:45:00 CET 2007
		133	- implement $coro->on_destroy.
		134	- Coro::Event blocking semantics have been changed,
		135	documented and - hopefully - improved.
		136	- fix nice adding, not subtracting, from priority.
		137	- fix ->prio and api_is_ready (patch by Mark Hinds).
		138	- fixed an assert ("... == prev__cctx->idle_te")
		139	that could errronously trigger.
		140	- fix various large and small memleaks.
		141	- use a (hopefully) more stable cancel implementation
		142	that immediately frees the coroutine data.
		143	- cede/cede_notself return a status now.
		144	- added Coro::guard function.
		145	- added a global coroutine pool for jobs (on my machine,
		146	I can create and execute 48k simple coros/s with async,
		147	and 128k coros with async_pool).
		148	- Coro::AIO now uses the coroutine priority as io priority.
		149
		150	3.2 Fri Dec 22 05:07:09 CET 2006
		151	- improve portability to slightly older perls.
		152	- use cleaner coroutine destruction.
		153	- simplify configuration for users.
		154	- optionally (unrecommended) prefer perl functions over
		155	their coro replacements.
		156
		157	3.11 Tue Dec 5 13:11:24 CET 2006
		158	- fixed some bogus assert's, but as perl.h disables assert even
		159	without NDEBUG (thank you very much), not too many people should
		160	notice (that did include myself). Andreas König noticed, though :)
		161	- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
		162	it. Also noticed by Andreas König :)
		163	- save/restore tainted status.
		164	- verified to pass the testsuite on my 5.9.5.
		165
		166	3.1 Mon Dec 4 23:03:40 CET 2006
		167	- INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
		168	- incompatible change: transfer flags are now per-state.
		169	- give a better error message on deadlock.
		170	- document Coro::nready.
		171	- enhanced testsuite.
		172
		173	3.01 Sun Dec 3 23:47:42 CET 2006
		174	- forgot to include Coro::Timer.

		185	- Coro::Event now uses asynccheck as prepare does not

		188	per event.
