1	Revision history for Perl extension Coro.	1	Revision history for Perl extension Coro.
2		2
3	3.0	3	TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
		4	TODO: maybe implement a default message channel, very much like Erlang
		5	(which is cool in a lot of important aspects (failures!),
		6	but very lacking in others (higher level ipc)).
		7
		8	- majorly improved Coro::Handle's performance with Coro::EV.
		9
		10	4.31 Wed Dec 5 12:32:39 CET 2007
		11	- remove warn statement form Coro::Util.
		12
		13	4.3 Tue Dec 4 20:33:14 CET 2007
		14	- calls to the idle function could cause stack corruption
		15	when the stack changed.
		16	- do no longer rely on the presence of EV::DNS if EV is used
		17	(because it is gone), but instead take avdantage of EV::ADNS
		18	if available.
		19	- add ($) prototypes to all functions in Coro::Storable.
		20	- use a conventional (safer) idle callback in Coro::EV.
		21	- do accept quickly in Coro::Debug to avoid endless loops.
		22
		23	4.22 Fri Nov 30 16:04:04 CET 2007
		24	- really use optimised versions for Event and EV in Coro::Util
		25	and Coro::Handle.
		26
		27	4.21 Sun Nov 25 10:48:59 CET 2007
		28	- fix a spurious memory read.
		29	- Coro::EV no longer keeps the eventloop "alive".
		30
		31	4.2 Fri Nov 9 20:47:05 CET 2007
		32	- enable/disable tracing from a new coroutine, not a pooled one.
		33	- fix a memleak in Coro::Event.
		34	- removed killall call from fork_eval.
		35	- made sure store_fd is already loaded so that fork_eval
		36	does not have to parse autoload in each subprocess.
		37	- only use assembly method if -O switch is in $Config{optimize}.
		38	- add (optional) Coro::EV module, so far the best event loop module
		39	directly supported by Coro.
		40	- if the event model is EV, use EV::DNS to resolve
		41	stuff in Coro::Util.
		42	- don't get confused by multiple event notifications in Coro::Handle.
		43	- initial support for EV (libevent interface).
		44	- require Event and EV using configure_requires, to force their existance.
		45
		46	4.13 Wed Oct 24 07:26:45 CEST 2007
		47	- add Coro::Storable::blocking_thaw.
		48	- use a vastly more complicated technique to localise
		49	$SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
		50	- use a coroutine for the idle callback Coro::Event,
		51	instead of running Event in the current coroutine context.
		52	This also catches recursive invocations.
		53	- actually report fork errors in gethostbyname and inet_aton.
		54
		55	4.11 Thu Oct 11 02:40:24 CEST 2007
		56	- port to threaded perls.
		57
		58	4.1 Thu Oct 11 02:38:16 CEST 2007
		59	- incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
		60	be local to each coro (see Coro::State).
		61	- incompatible change: for very deep reasons, cede and cede_notself
		62	cannot return anything, so nothing will be returned.
		63	- possibly bring back 5.10 compatibility (untested).
		64	- work around stupid (and wrong) warning on 5.10 :(.
		65	- overlay the saved state over the context stack. This saves
		66	a few hundred bytes per coroutine on average and also
		67	speeds up context switching a bit.
		68	- further tune default stack sizes.
		69	- (more) correctly calculate stack usage in coro_rss.
		70	- Coro::Storable::blocking_* did not properly lock
		71	resulting in races between coroutines.
		72	- added Coro::Storable::guard.
		73	- stopping to trace a coroutine could destroy the cctx of
		74	an unrelated coroutine.
		75	- explain the relationship between Perl and C coroutines in
		76	more detail in Coro::State.
		77	- Coro::Util::inet_aton did not short-circuit dotted quad forms,
		78	causing a fork per resolve. This also affected Coro::Socket.
		79	- switch to a separate stack in $coro->call/eval to avoid
		80	invalidating pointers.
		81
		82	4.03 Sat Oct 6 21:24:00 CEST 2007
		83	- added Coro::throw method.
		84	- minor code cleanups.
		85
		86	4.02 Sat Oct 6 02:36:47 CEST 2007
		87	- fix a very minor per-coroutine memleak (a single codereference).
		88	- fixed a bug where the currently in-use c context would be freed
		89	prematurely (can happen only when programs change the stacksize
		90	or use tracing).
		91	- tracing can no longer keep a coro alive after it terminated.
		92	- do static branch prediction in the common path for gcc. gives
		93	about 2-5% speed improvement here.
		94
		95	4.01 Fri Oct 5 22:10:49 CEST 2007
		96	- instead of recreating a standard output handle we simply
		97	use STDOUT, which is faster and hopefully more robust.
		98
		99	4.0 Fri Oct 5 12:56:00 CEST 2007
		100	- incompatibly changed Coro::Storable::freeze.
		101	- major new feature: added Coro::Debug, for interactive coroutine
		102	debugging, tracing and much more.
		103	- major bug fix: unbelievable, but true: $_, $/ and many other
		104	"saved" variables actually weren't being saved. This has been fixed,
		105	of course, while increasing performance while losing all the save
		106	flags.
		107	- save flags are gone, and all the api functions dealing with them.
		108	- added Coro::Semaphore::adjust.
		109	- added Coro::Util::fork_eval.
		110	- added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
		111	- added Coro::killall.
		112	- reduce initial stack sizes to allow for "micro-coroutines".
		113	- better async_pool resource management, moved parts of async_pool
		114	handling to XS (major speed improvement).
		115	- actually croak before modifying important data structures.
		116	- refuse to transfer while compiling.
		117	- possibly support eval EXPR better now.
		118	- enable assembly per default on linux+bsd x86+amd64.
		119	- all internal members were renamed _something for easier subclassing.
		120	- many minor tweaks.
		121
		122	3.63 Wed May 16 14:10:06 CEST 2007
		123	- implement handcoded assembly for x86/amd64 SVR ABI.
		124
		125	3.62 Fri Apr 27 21:36:06 CEST 2007
		126	- upgrade libcoro (which might set unwind info correctly).
		127	- change default on linux to setjmp/longjmp.
		128
		129	3.61 Thu Apr 19 12:36:18 CEST 2007
		130	- Coro::Storable caused an endless loop when thawing invalid
		131	pst's sometimes.
		132	- use a Semaphore in Coro::Storable, as Storable doesn't
		133	seem to be reentrant (although it is documented to
		134	be threadsafe...).
		135	- fix Coro::Signal to bring back the original unreliable
		136	but stateful semantics.
		137	- fixed a lot of typos in Coro.pm (patch submitted by David
		138	Steinbrunner, which applied flawlessly).
		139
		140	3.6 Sat Apr 14 17:13:31 CEST 2007
		141	- added some bugfixes to get eg/myhttpd working again.
		142	- added Coro::Storable for often-cede'ing freeze/thaw.
		143	- try to do a clean exit when a coroutine calls exit
		144	(EXPERIMENTAL).
		145	- got rid of indirect call through _coro_init.
		146	- updated the partly antique examples in eg/ to
		147	work again and be a bit less magic, too.
		148	- fixed Coro::Signal semantics to work as documented again.
		149
		150	3.55 Sun Mar 25 01:20:47 CET 2007
		151	- add SAVE_DEFFH to save the default filehandle and enable
		152	it by default.
		153	- finally move socket-operations from Coro::Socket to Coro::Handle
		154	to be able to unblock foreign sockets.
		155	- add Coro::State::save_also and guarded_save.
		156	- add count accessor to Coro::Semaphore.
		157	- add Coro::State::cctx_stacksize.
		158	- just for the fun of it, do not rely on implicit context,
		159	which can dramatically improve performance, but people
		160	using windows-process-emulation perls do not care much about
		161	performance.
		162
		163	3.51 Sun Mar 4 14:18:04 CET 2007
		164	- fixed a problem when you weakened references to Coro::State's
		165	(patch by Yuval Kogman).
		166
		167	3.501 Wed Feb 28 12:44:07 CET 2007
		168	- rename some global symbols as macosx from hell redefines
		169	them without asking.
		170
		171	3.5 Tue Feb 13 20:22:53 CET 2007
		172	- do AnyEvent model detection earlier, avoiding problems
		173	caused by first using AnyEvent and later Coro::Event.
		174	- implement and document Coro::Event event objects.
		175	- fix a potential problem in Coro::Event causing crashes.
		176	- initialise PL_comppad when creating a new coroutine,
		177	avoids crashes on early coro destruction.
		178
		179	3.41 Mon Jan 22 19:19:49 CET 2007
		180	- readline on Coro::Handle did not support undefined $/,
		181	nor did it deliver partial lines on EOF or error.
		182	- implement malloc fallback for stack allocation because
		183	stupid broken idiotic OSX has a stupid broken
		184	idiotic fits-the-whole-os mmap "implementation" and
		185	my dick feels longer if Coro is portable even to
		186	obsolete platforms.
		187
		188	3.4 Fri Jan 19 21:52:54 CET 2007
		189	- remove t/09_timer.t, as it isn't really testing much
		190	but was rather flaky in practise.
		191	- async_pool coro would keep arguments and callback alive until
		192	it was reused.
		193	- cancellation of a coroutine could cause spurious idle calls
		194	in cede_notself.
		195
		196	3.3 Sat Jan 6 03:45:00 CET 2007
		197	- implement $coro->on_destroy.
		198	- Coro::Event blocking semantics have been changed,
		199	documented and - hopefully - improved.
		200	- fix nice adding, not subtracting, from priority.
		201	- fix ->prio and api_is_ready (patch by Mark Hinds).
		202	- fixed an assert ("... == prev__cctx->idle_te")
		203	that could errronously trigger.
		204	- fix various large and small memleaks.
		205	- use a (hopefully) more stable cancel implementation
		206	that immediately frees the coroutine data.
		207	- cede/cede_notself return a status now.
		208	- added Coro::guard function.
		209	- added a global coroutine pool for jobs (on my machine,
		210	I can create and execute 48k simple coros/s with async,
		211	and 128k coros with async_pool).
		212	- Coro::AIO now uses the coroutine priority as io priority.
		213
		214	3.2 Fri Dec 22 05:07:09 CET 2006
		215	- improve portability to slightly older perls.
		216	- use cleaner coroutine destruction.
		217	- simplify configuration for users.
		218	- optionally (unrecommended) prefer perl functions over
		219	their coro replacements.
		220
		221	3.11 Tue Dec 5 13:11:24 CET 2006
		222	- fixed some bogus assert's, but as perl.h disables assert even
		223	without NDEBUG (thank you very much), not too many people should
		224	notice (that did include myself). Andreas König noticed, though :)
		225	- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
		226	it. Also noticed by Andreas König :)
		227	- save/restore tainted status.
		228	- verified to pass the testsuite on my 5.9.5.
		229
		230	3.1 Mon Dec 4 23:03:40 CET 2006
		231	- INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
		232	- incompatible change: transfer flags are now per-state.
		233	- give a better error message on deadlock.
		234	- document Coro::nready.
		235	- enhanced testsuite.
		236
		237	3.01 Sun Dec 3 23:47:42 CET 2006
		238	- forgot to include Coro::Timer.
