1	Revision history for Perl extension Coro.	1	Revision history for Perl extension Coro.
2		2
3	TODO: check wether stack-sharing is still effective	3	TODO: localise SIG{__DIE__} and/or __WARN__
4	TODO: more effective stack sharing by having one "default stack" for "simple" coroutines?	4	TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
5	TODO: verify exception frame changes and force stack copies?	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)).
6		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	- further tune default stack sizes.
		17	- (more) correctly calculate stack usage in coro_rss.
		18
		19	4.03 Sat Oct 6 21:24:00 CEST 2007
		20	- added Coro::throw method.
		21	- minor code cleanups.
		22
		23	4.02 Sat Oct 6 02:36:47 CEST 2007
		24	- fix a very minor per-coroutine memleak (a single codereference).
		25	- fixed a bug where the currently in-use c context would be freed
		26	prematurely (can happen only when programs change the stacksize
		27	or use tracing).
		28	- tracing can no longer keep a coro alive after it terminated.
		29	- do static branch prediction in the common path for gcc. gives
		30	about 2-5% speed improvement here.
		31
		32	4.01 Fri Oct 5 22:10:49 CEST 2007
		33	- instead of recreating a standard output handle we simply
		34	use STDOUT, which is faster and hopefully more robust.
		35
		36	4.0 Fri Oct 5 12:56:00 CEST 2007
		37	- incompatibly changed Coro::Storable::freeze.
		38	- major new feature: added Coro::Debug, for interactive coroutine
		39	debugging, tracing and much more.
		40	- major bug fix: unbelievable, but true: $_, $/ and many other
		41	"saved" variables actually weren't being saved. This has been fixed,
		42	of course, while increasing performance while losing all the save
		43	flags.
		44	- save flags are gone, and all the api functions dealing with them.
		45	- added Coro::Semaphore::adjust.
		46	- added Coro::Util::fork_eval.
		47	- added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
		48	- added Coro::killall.
		49	- reduce initial stack sizes to allow for "micro-coroutines".
		50	- better async_pool resource management, moved parts of async_pool
		51	handling to XS (major speed improvement).
		52	- actually croak before modifying important data structures.
		53	- refuse to transfer while compiling.
		54	- possibly support eval EXPR better now.
		55	- enable assembly per default on linux+bsd x86+amd64.
		56	- all internal members were renamed _something for easier subclassing.
		57	- many minor tweaks.
		58
		59	3.63 Wed May 16 14:10:06 CEST 2007
		60	- implement handcoded assembly for x86/amd64 SVR ABI.
		61
		62	3.62 Fri Apr 27 21:36:06 CEST 2007
		63	- upgrade libcoro (which might set unwind info correctly).
		64	- change default on linux to setjmp/longjmp.
		65
		66	3.61 Thu Apr 19 12:36:18 CEST 2007
		67	- Coro::Storable caused an endless loop when thawing invalid
		68	pst's sometimes.
		69	- use a Semaphore in Coro::Storable, as Storable doesn't
		70	seem to be reentrant (although it is documented to
		71	be threadsafe...).
		72	- fix Coro::Signal to bring back the original unreliable
		73	but stateful semantics.
		74	- fixed a lot of typos in Coro.pm (patch submitted by David
		75	Steinbrunner, which applied flawlessly).
		76
		77	3.6 Sat Apr 14 17:13:31 CEST 2007
		78	- added some bugfixes to get eg/myhttpd working again.
		79	- added Coro::Storable for often-cede'ing freeze/thaw.
		80	- try to do a clean exit when a coroutine calls exit
		81	(EXPERIMENTAL).
		82	- got rid of indirect call through _coro_init.
		83	- updated the partly antique examples in eg/ to
		84	work again and be a bit less magic, too.
		85	- fixed Coro::Signal semantics to work as documented again.
		86
		87	3.55 Sun Mar 25 01:20:47 CET 2007
		88	- add SAVE_DEFFH to save the default filehandle and enable
		89	it by default.
		90	- finally move socket-operations from Coro::Socket to Coro::Handle
		91	to be able to unblock foreign sockets.
		92	- add Coro::State::save_also and guarded_save.
		93	- add count accessor to Coro::Semaphore.
		94	- add Coro::State::cctx_stacksize.
		95	- just for the fun of it, do not rely on implicit context,
		96	which can dramatically improve performance, but people
		97	using windows-process-emulation perls do not care much about
		98	performance.
		99
		100	3.51 Sun Mar 4 14:18:04 CET 2007
		101	- fixed a problem when you weakened references to Coro::State's
		102	(patch by Yuval Kogman).
		103
		104	3.501 Wed Feb 28 12:44:07 CET 2007
		105	- rename some global symbols as macosx from hell redefines
		106	them without asking.
		107
		108	3.5 Tue Feb 13 20:22:53 CET 2007
		109	- do AnyEvent model detection earlier, avoiding problems
		110	caused by first using AnyEvent and later Coro::Event.
		111	- implement and document Coro::Event event objects.
		112	- fix a potential problem in Coro::Event causing crashes.
		113	- initialise PL_comppad when creating a new coroutine,
		114	avoids crashes on early coro destruction.
		115
		116	3.41 Mon Jan 22 19:19:49 CET 2007
		117	- readline on Coro::Handle did not support undefined $/,
		118	nor did it deliver partial lines on EOF or error.
		119	- implement malloc fallback for stack allocation because
		120	stupid broken idiotic OSX has a stupid broken
		121	idiotic fits-the-whole-os mmap "implementation" and
		122	my dick feels longer if Coro is portable even to
		123	obsolete platforms.
		124
		125	3.4 Fri Jan 19 21:52:54 CET 2007
		126	- remove t/09_timer.t, as it isn't really testing much
		127	but was rather flaky in practise.
		128	- async_pool coro would keep arguments and callback alive until
		129	it was reused.
		130	- cancellation of a coroutine could cause spurious idle calls
		131	in cede_notself.
		132
		133	3.3 Sat Jan 6 03:45:00 CET 2007
		134	- implement $coro->on_destroy.
		135	- Coro::Event blocking semantics have been changed,
		136	documented and - hopefully - improved.
		137	- fix nice adding, not subtracting, from priority.
		138	- fix ->prio and api_is_ready (patch by Mark Hinds).
		139	- fixed an assert ("... == prev__cctx->idle_te")
		140	that could errronously trigger.
		141	- fix various large and small memleaks.
		142	- use a (hopefully) more stable cancel implementation
		143	that immediately frees the coroutine data.
		144	- cede/cede_notself return a status now.
		145	- added Coro::guard function.
		146	- added a global coroutine pool for jobs (on my machine,
		147	I can create and execute 48k simple coros/s with async,
		148	and 128k coros with async_pool).
		149	- Coro::AIO now uses the coroutine priority as io priority.
		150
		151	3.2 Fri Dec 22 05:07:09 CET 2006
		152	- improve portability to slightly older perls.
		153	- use cleaner coroutine destruction.
		154	- simplify configuration for users.
		155	- optionally (unrecommended) prefer perl functions over
		156	their coro replacements.
		157
		158	3.11 Tue Dec 5 13:11:24 CET 2006
		159	- fixed some bogus assert's, but as perl.h disables assert even
		160	without NDEBUG (thank you very much), not too many people should
		161	notice (that did include myself). Andreas König noticed, though :)
		162	- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
		163	it. Also noticed by Andreas König :)
		164	- save/restore tainted status.
		165	- verified to pass the testsuite on my 5.9.5.
		166
		167	3.1 Mon Dec 4 23:03:40 CET 2006
		168	- INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
		169	- incompatible change: transfer flags are now per-state.
		170	- give a better error message on deadlock.
		171	- document Coro::nready.
		172	- enhanced testsuite.
		173
		174	3.01 Sun Dec 3 23:47:42 CET 2006
		175	- forgot to include Coro::Timer.
		176
		177	3.0 Sun Dec 3 22:57:25 CET 2006

10	- Coro::Event could cause livelocks if it was used but	184	- Coro::Event could cause livelocks if it was used but
11	Event watchers were used directly.	185	no Coro::Event watchers were used.
		186	- Coro::Event now uses asynccheck as prepare does not
		187	check for changed watchers.
		188	- Coro::Event allows multiple waiting coros and will wake up one
		189	per event.
12	- Coro::Event should be cleaner and more efficient now.	190	- Coro::Event should be cleaner and more efficient now.
		191	- new utility function Coro::unblock_sub.
		192	- document the sad fact that Event is no longer reentrant.
		193	- putting a coroutine into the ready queue twice could under
		194	some circumstances lead to stack corruption.
13	- minor incompatibility: subclassing is supported directly now	195	- minor incompatibility: subclassing Coro::State is supported
14	without going through a _coro_state member.	196	directly now without going through a _coro_state member.
15	- state/coro switching is much faster now.	197	- state/coro switching is much faster now.

		203	- implement enhanced support for valgrind.
		204	- implement is_ready and return value for ready.
		205	- removed Coro::Cont, it was a misnomer (it's generators),
		206	and it was somewhat annoying to get it right. Will come back
		207	if somebody asks for it :)
		208	- many ->wait methods and Coro::Event could return
		209	spuriously without the event having happened.
