6	but very lacking in others (higher level ipc)).
7		6
		7	- implement Coro->cancel in XS for a 20% speed improvement, and to
		8	be able to implement mutual cancellation.
		9	- cancelling a coro while it itself is cancelling another coro is
		10	now supported and working, instead of triggering an assertion.
		11	- be a bit more crash-resistant when calling (buggy) on_destroy
		12	callbacks (best effort).
		13
		14	5.372 Wed Feb 23 06:14:30 CET 2011
		15	- apparently mingw doesn't provide a working gettimeofday, try to
		16	work around that by relying on Time::HiRes (indirectly brought to
		17	my attention by Max Maischein).
		18	- fix some portability issues when Time::HiRes was used.
		19
		20	5.371 Mon Feb 21 14:36:08 CET 2011
		21	- backport to windows process emulation code again.
		22
		23	5.37 Sat Feb 19 07:49:44 CET 2011
		24	- add a big "Coro thread life cycle" section to "man Coro".
		25	- try a tentative workaround against the breakage that 5.13 has
		26	introduced without depreciation period. sigh.
		27	- no longer use Time::HiRes if gettimeofday is available, which
		28	saves quite a lot of memory.
		29
		30	5.36 Sun Feb 13 05:33:41 CET 2011
		31	- automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
		32	Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
		33	method call.
		34	- undocument Coro::Timer::sleep and obsolete whole module.
		35	- optimise Coro::Timer::timeout memory and cpu usage.
		36	- slightly updated Coro::Intro for recent changes.
		37	- do not initialise PL_dirty anymore.
		38
		39	5.25 Thu Nov 11 01:08:39 CET 2010
		40	- try a different approach on netbsd - netbsd 5 finally has marginally
		41	working pthreads, but still broken ucontext/sigaltstack.
		42	- openbsd 4.8 finally got their act together, Coro works out of the box
		43	with asm, setjmp and pthreads (no change, just informational).
		44
		45	5.24 Sat Oct 23 11:27:12 CEST 2010
		46	- port to the EV 4.0 API.
		47	- work around bugs in mingw32, making strawberry perl work
		48	out of the box.
		49	- correctly modify Coro::AIO function prototypes
		50	so that they reflect the "no optional parameters" rule.
		51	- "ported" libcoro to C++.
		52
		53	5.23 Mon May 17 18:50:42 CEST 2010
		54	- be more resistant to ordering changes when initialising
		55	Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
		56	Waldorf).
		57	- document that perl 5.12 deliberately removed support for cloning.
		58
		59	5.22 Wed Apr 14 03:55:35 CEST 2010
		60	- correctly return udnef on errors in Coro::Handle::read/write
		61	(testcase by Marc Mims).
		62	- convert Coro::Util into a "perl compatibility wrapper" - the functions
		63	are less useful now, but are drop-in replacements for existing
		64	functions, listing better alternatives in the documentation. This also
		65	fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
		66	with Coro::Util::inet_aton.
		67	- do not override $Coro::idle unconditionally in Coro.pm, as other
		68	modules could have provided their own idle coro already
		69	(for exmaple, Coro::AnyEvent).
		70	- fix Coro::Util::gethost* functions.
		71	- Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
		72
		73	5.21 Wed Dec 16 07:19:51 CET 2009
		74	- automatically load Coro::AnyEvent when AnyEvent and Coro are used
		75	together.
		76	- add some examples on how to combine other event loops with Coro in
		77	Coro::AnyEvent, and how to run it (and not to block). Seems to be
		78	the most common source of confusion.
		79	- try to catch people naively blocking in an event callback.
		80	- work around the perl filehandle bug issue in conjunction with
		81	older common::sense (as indirectly pointed out by ZSystem).
		82	- clarify the "not from signal handlers" section.
		83
		84	5.2 Sun Oct 4 14:54:24 CEST 2009
		85	- Coro::Storable destroyed the prototypes of the functions it wrapped.
		86	- export rouse_cb and rouse_wait by default now.
		87	- fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
		88	- new method $state->swap_sv.
		89	- added section on "windows process emulation" to the manpage,
		90	after a not-so-fruitful (nor-friendly) "discussion" with chip
		91	salzenberg (discussion implies arguments, but his only arguments
		92	were ad-hominems, one wonders why he started it in the first
		93	place). I hope this explains it well enough for him to understand,
		94	and maybe well enough for others to understand.
		95	- use common::sense everywhere now.
		96	- idle callbacks are no longer supported, use idle coros instead.
		97	- print a thread listing when a deadlock is detected.
		98
		99	5.17 Sat Aug 22 23:09:31 CEST 2009
		100	- work around a bug in the perl debugger causing crashes
		101	when running under the debugger by marking _pool_handler as nodebug.
		102	- speed up Coro::async considerably.
		103	- try some hacks to get netbsd to work "more often" - their broken
		104	setjmp/longjmp, ucontext and phtreads are really hard on Coro.
		105	- convert Coro to AE 5.0 API.
		106
		107	5.162 Tue Jul 28 04:04:03 CEST 2009
		108	- perl 5.8.2 is now minimum requirement.
		109	- skip t/19_handle.t on broken windows perls.
		110
		111	5.161 Wed Jul 22 04:47:38 CEST 2009
		112	- Coro::AnyEvent::poll could have a different prototype when EV was
		113	used as backend (analyzed by Tatsuhiko Miyagawa).
		114	- Coro::AnyEvent errornously initialised the event loop when loaded,
		115	not on demand.
		116	- try to workaround rare */t/01_unblock.t failures.
		117
		118	5.16 Tue Jul 21 01:44:37 CEST 2009
		119	- Coro::AnyEvent failed to hook into the event loop
		120	when no threads had been readied between detecting
		121	the event loop and actually running it.
		122	- considerably speed up Coro::Select by taking avdantage
		123	of AnyEvent > 4.8 and some other optimisations.
		124	- implement paragraph readline mode in Coro::Handle
		125	(based on patches by Zsbán Ambrus).
		126	- replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
		127	and analyzed by Yasuhiro MATSUMOTO).
		128	- clarified libcoro license and copyright.
		129	- someone stole my EXTRA_META!!!
		130	- implement Coro::Select::patch_pp_sselect and it's brother,
		131	for hardcode select overriding.
		132
		133	5.151 Mon Jul 6 05:41:57 CEST 2009
		134	- backport to windows process emulation code again (patch by
		135	Yasuhiro MATSUMOTO).
		136	- slightly update Coro::MakeMaker.
		137
		138	5.15 Tue Jun 30 10:28:06 CEST 2009
		139	- deprecate Coro::Socket, document how to get ipv6 support via
		140	AnyEvent::Socket instead.
		141	- implement signal->wait ($cb) interface, similar to semaphores.
		142	- work around SvOK not supporting getmagic, so we have to getmagic
		143	to test for undef :/ (reported by Matthias Waldorf).
		144	- load Coro::AnyEvent in all modules using AnyEvent.
		145	- work around perl corrupting our internal data structures,
		146	reported by Tokuhiro Matsuno.
		147	- enable per-coroutine real and cpu time gathering
		148	(Coro::State::enable_times).
		149
		150	5.14 Wed Jun 24 01:37:48 CEST 2009
		151	- provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
		152	as this seems to have been a difficult concept (poll, sleep, idle,
		153	idle_upto).
		154	- add Coro::AnyEvent::readable/writable functions.
		155	- clarify Coro::EV/Event/AnyEvent manpages.
		156	- free per-thread global scalars in the thread calling ->cancel, to
		157	avoid crashes when $_, $@ etc., are magical but some of those
		158	had already been freed.
		159	- "unexperimentalise" the callback interface for Coro::Semaphore.
		160	- speed up ready queue management/context switching by using a linked
		161	list instead of an array (~5-10%).
		162	- implement "watch" command in Coro::Debug shells.
		163	- for fun, implement time-slicing as an example in the manpage.
		164	- if AnyEvent detects EV or Event, but we don't have Coro::EV or
		165	Coro::Event, use the normal AnyEvent handling instead of dieing
		166	(the same is true for Coro::Handle).
		167	- properly document Coro::EV::timed_io_once.
		168	- avoid unneccessary ->cancel calls in Coro::Handle.
		169	- maybe make it work on mingw32 with win32 backend
		170	(based on patch by Yasuhiro Matsumoto).
		171
		172	5.132 Fri May 29 09:00:39 CEST 2009
		173	- do not keep a reference to the argument itself in
		174	Coro::Semaphore::guard, as it could change later.
		175	- support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
		176	should support a prepare callback.
		177
		178	5.131 Mon Mar 16 23:20:37 CET 2009
		179	- implement and document Coro->suspend, Coro->resume.
		180	- fix Coro::Select implementation to not (often) close
		181	the passed file descriptors (testcase provided by pippijn).
		182
		183	5.13 Mon Dec 15 21:51:42 CET 2008
		184	- EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
		185	- don't set diehook to C<undef> but instead to NULL, to avoid
		186	spurious warnings.
		187	- fix a lot of bugs in Coro::SemaphoreSet.
		188	- Coro::SemaphoreSet will less often create a semaphore needlessly.
		189	- add Coro::SemaphoreSet::count and wait methods.
		190	- take advantage of the new Guard module.
		191	- deprecate Coro::guard.
		192	- try to fix the dreaded 01_unblock tests once more. I hate it when
		193	testsuites need more fixing than the code they are supposed to test.
		194	- croak in more cases when a required callback isn't resolvable.
		195	- fix some minor issues in Coro::State->call/eval.
		196	- use current coroutine context instead of a temporary one
		197	when temporarily switching to another coroutine.
		198	- do not call C-level on_destroy handlers during global destruction,
		199	to avoid needless segfaults.
		200
		201	5.12 Sun Dec 7 13:30:38 CET 2008
		202	- add default config for MirOS, which seems to be a bug-to-bug
		203	compatible fork of openbsd ("world domination by releasing
		204	openbsd cvs before the openbsd folks do it" or so :).
		205	- free_padlist did destroy the names pad, not good, but didn't
		206	seem to bother perl - this could fix issues such as eval ""
		207	inside a function called from multiple coroutines.
		208	- use a different method to detect destruction time.
		209	- be more careful when freeing padlists just before global
		210	destruction.
		211	- fixed and expanded the call/cc example.
		212	- renamed _terminate to _coro_run.
		213	- new method Coro::Channel->shutdown.
		214	- try pthreads on openbsd <4.4 (broken sigaltstack, will
		215	pthreads fare better?).
		216	- be less picky about destroying "a" running coroutine.
		217
		218	5.11 Tue Nov 25 21:49:05 CET 2008
		219	- DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
		220	working code with failed assertions, introducing more bugs than
		221	it fixes, requiring elaborate workarounds :(
		222
		223	5.1 Mon Nov 24 08:54:59 CET 2008

		237	- automatically load Coro::AnyEvent in Coro::Handle.
		238	- wrap ->cancel calls in eval inside Coro::Handle as EV watchers

		240	- speed up generic anyevent methods in Coro::Handle by using rouse
		241	callbacks.
		242	- allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
		243	others. It also makes the debugger happier, as you can trace
		244	through the idle threads now.
		245	- add comppad_name* and hints ($^H, %^H) to per-thread variables.
