6		8
7	TODO: tutorial	9	- check that perl slots actually have enough space to hold
8	TODO: in_eval, PL_tained	10	interpreter variables.
		11	- untested port to perl 5.19 (64 bit tmps indices) (reported
		12	by Andreas König).
		13	- croak when cancel is called without a thread context.
		14
		15	6.37 Tue Mar 4 13:27:33 CET 2014
		16	- sigh, removed leftover debugging code from debugging a
		17	perl bug, of all things.
		18
		19	6.36 Tue Mar 4 07:11:59 CET 2014
		20	- semaphores would not clear the destroy hook when interrupted
		21	by ->throw, causing segfaults or worse.
		22	- ->throw on a thread waiting for a semaphore did not acquire
		23	the semaphore, but also didn't wake up other waiters,
		24	possibly causing a deadlock.
		25	- "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
		26	to report a full stacktrace, which should help find out
		27	where the actual call is.
		28	- "atomically" destroy data in slf_destroy, because it is
		29	the right thing to do, just in case.
		30	- disable ecb.h libm dependency, to compile on ancient systems
		31	or under adverse conditions.
		32
		33	6.33 Mon Nov 18 11:26:27 CET 2013
		34	- do not crash when freeing padlists with holes (in 5.18).
		35	- tentative SVt_BIND 5.19 port/fix.
		36
		37	6.32 Tue Nov 5 15:35:35 CET 2013
		38	- use a new algorithm to derive padlists for perl 5.18. The old
		39	one could lead to 0-pointer accesses inside perl (reported
		40	by Darin McBride).
		41
		42	6.31 Thu May 9 07:39:48 CEST 2013
		43	- Coro::AIO requests would crash if the thread was ready'd
		44	while the request was ongoing.
		45
		46	6.29 Wed May 8 02:55:18 CEST 2013
		47	- when an on_destroy handler destructs the coro currently being
		48	destructed a perl scalar could be accessed after being freed,
		49	likely causing a crash.
		50
		51	6.28 Wed Mar 6 06:58:02 CET 2013
		52	- clean remnants of existing __DIE__ and __WARN__ handlers so
		53	they lose their magic and will not cause segfaults later
		54	(testcase by Andrey Sagulin).
		55	- improved Coro::State documentation a bit.
		56	- Coro::Debug::command now flushes the output.
		57	- add hack detection code for x32 abi, because the braindead slugs
		58	who designed that made it look exactly like x86_64 without
		59	providing proper compile time symbols to test for it. as a result,
		60	this detection cannot work reliably.
		61	- valgrind stack registering was broken.
		62	- do not rely on Time::HiRes anymore in Coro::Debug.
		63
		64	6.23 Fri Dec 7 23:36:37 CET 2012
		65	- use experimental fiber implementation on native windows
		66	perls.
		67	- use sizeof (void *) as multiplication factor for stack sizes,
		68	to accomodate the totally braindamaged microsoft 64 bit "os".
		69	- changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
		70	activeperl 5.16 crashes when PerlIO_define_layer is called due
		71	to some bug in the perl dll, strawberry perl at least passes
		72	the testsuite.
		73	- implement Coro::Handle->peeraddr/host/port, for slightly
		74	improved compatibility with LWP.
		75	- implement 5.17 compatibility by almost blindly applying a
		76	good-looking patch by Father Chrysostomos.
		77	- move stack management functions into libcoro 3.
		78	- libcoro version 3 "released".
		79	- support magic values as timed_io_once args.
		80	- recommend AnyEvent 7+ or EV 4+, also require EV
		81	version 4 or newer for Coro::EV.
		82
		83	6.10 Tue Oct 9 01:14:27 CEST 2012
		84	- updated ecb.h, it had a typo that caused it to not compile on many
		85	big endian systems (reported by many people).
		86	- disable memory fences in ecb.h to improve portability.
		87
		88	6.09 Sat Oct 6 23:25:02 CEST 2012
		89	- Coro::EV I/O watchers were not interruptible by exceptions
		90	(Coro::State::throw) (testcase by sten).
		91	- ->throw now puts threads into the ready queue, as this seems to
		92	be expected by existing code, and code that doesn't cope with spurious
		93	wakeups needs fixing anyway.
		94	- use fd -1 in mmap.
		95	- cast I32 to int in error message printf.
		96	- warn about broken so-called "hardened" kernels.
		97
		98	6.08 Fri Apr 13 12:05:47 CEST 2012
		99	- be more aggressive about exiting like perl does - formerly,
		100	exiting from the non-main thread would not execute END blocks.
		101
		102	6.07 Fri Nov 11 21:21:48 CET 2011
		103	- work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
		104	- update ecb.h.
		105
		106	6.06 Mon Aug 8 23:59:48 CEST 2011
		107	- cygwin unfortunately patches the stack at runtime, so we use the pthreads
		108	backend, which is an order of magnitude slower. unfortunately, cygwins
		109	pthread implementation isn't very complete either, so allocate the stack
		110	twice just to be sure.
		111	(note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
		112	in its ithreaded perl - best recompile cygwin and use the 'w'indows
		113	backend for much better performance. also disable ithreads for
		114	even better performance...).
		115
		116	6.05 Thu Aug 4 21:36:36 CEST 2011
		117	- blush, condvar values would not be propagated from send to recv anymore
		118	(reported by Chip Salzenberg).
		119	- use exponential increase for the readline buffer length in
		120	Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
		121
		122	6.04 Wed Aug 3 17:15:45 CEST 2011
		123	- use even more efficient and more compatible condvars for
		124	compatibility to AnyEvent 6.x :)
		125	- more inconsequential ecb.h updates.
		126
		127	6.03 Wed Aug 3 11:41:30 CEST 2011
		128	- change how Coro patches AnyEvent condvars for compatibility to
		129	AnyEvent 6.x.
		130	- update ecb.h, to no longer include <pthread.h> in case WinNT.h
		131	hasn't been included.
		132
		133	6.02 Wed Jul 13 04:35:19 CEST 2011
		134	- "improve portability to Gentoo" - gentoo manages to put perl variables
		135	in memory areas that are farther than 2gb apart, which the jit couldn't
		136	handle and barfed. now it's just a bit slower on gentoo and similar
		137	systems.
		138
		139	6.01 Sun Jul 3 12:31:14 CEST 2011
		140	- workarounds are good, but the test for whether pthreads are used
		141	was not good. thisone should be better.
		142	- check differently whether gcc generates cfi instructions itself.
		143
		144	6.0 Wed Jun 29 19:43:35 CEST 2011

		147	- implement a JIT compiler for part of the thread switch code,
		148	which gives a 50% speed improvement on threaded perls, and
		149	about 4% on non-thraeded perls (so threaded perls now finally
		150	reach about half the speed of non-threaded perls).
		151	- slightly modernise Coro::Intro, add section about rouse functions.
