1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO. 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: maybe implement a default message channel, very much like Erlang's 4TODO: channel->maxsize(newsize)?
5 actor model (which is cool in a lot of important aspects (failures!), 5TODO: __GCC_HAVE_DWARF2_CFI_ASM
6 but very lacking in others (higher level ipc)). 6
76.31 Thu May 9 07:39:48 CEST 2013
8 - Coro::AIO requests would crash if the thread was ready'd
9 while the request was ongoing.
10
116.29 Wed May 8 02:55:18 CEST 2013
12 - when an on_destroy handler destructs the coro currently being
13 destructed a perl scalar could be accessed after being freed,
14 likely causing a crash.
15
166.28 Wed Mar 6 06:58:02 CET 2013
17 - clean remnants of existing __DIE__ and __WARN__ handlers so
18 they lose their magic and will not cause segfaults later
19 (testcase by Andrey Sagulin).
20 - improved Coro::State documentation a bit.
21 - Coro::Debug::command now flushes the output.
22 - add hack detection code for x32 abi, because the braindead slugs
23 who designed that made it look exactly like x86_64 without
24 providing proper compile time symbols to test for it. as a result,
25 this detection cannot work reliably.
26 - valgrind stack registering was broken.
27 - do not rely on Time::HiRes anymore in Coro::Debug.
28
296.23 Fri Dec 7 23:36:37 CET 2012
30 - use experimental fiber implementation on native windows
31 perls.
32 - use sizeof (void *) as multiplication factor for stack sizes,
33 to accomodate the totally braindamaged microsoft 64 bit "os".
34 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
35 activeperl 5.16 crashes when PerlIO_define_layer is called due
36 to some bug in the perl dll, strawberry perl at least passes
37 the testsuite.
38 - implement Coro::Handle->peeraddr/host/port, for slightly
39 improved compatibility with LWP.
40 - implement 5.17 compatibility by almost blindly applying a
41 good-looking patch by Father Chrysostomos.
42 - move stack management functions into libcoro 3.
43 - libcoro version 3 "released".
44 - support magic values as timed_io_once args.
45 - recommend AnyEvent 7+ or EV 4+, also require EV
46 version 4 or newer for Coro::EV.
47
486.10 Tue Oct 9 01:14:27 CEST 2012
49 - updated ecb.h, it had a typo that caused it to not compile on many
50 big endian systems (reported by many people).
51 - disable memory fences in ecb.h to improve portability.
52
536.09 Sat Oct 6 23:25:02 CEST 2012
54 - Coro::EV I/O watchers were not interruptible by exceptions
55 (Coro::State::throw) (testcase by sten).
56 - ->throw now puts threads into the ready queue, as this seems to
57 be expected by existing code, and code that doesn't cope with spurious
58 wakeups needs fixing anyway.
59 - use fd -1 in mmap.
60 - cast I32 to int in error message printf.
61 - warn about broken so-called "hardened" kernels.
62
636.08 Fri Apr 13 12:05:47 CEST 2012
64 - be more aggressive about exiting like perl does - formerly,
65 exiting from the non-main thread would not execute END blocks.
66
676.07 Fri Nov 11 21:21:48 CET 2011
68 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
69 - update ecb.h.
70
716.06 Mon Aug 8 23:59:48 CEST 2011
72 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
73 backend, which is an order of magnitude slower. unfortunately, cygwins
74 pthread implementation isn't very complete either, so allocate the stack
75 twice just to be sure.
76 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
77 in its ithreaded perl - best recompile cygwin and use the 'w'indows
78 backend for much better performance. also disable ithreads for
79 even better performance...).
80
816.05 Thu Aug 4 21:36:36 CEST 2011
82 - blush, condvar values would not be propagated from send to recv anymore
83 (reported by Chip Salzenberg).
84 - use exponential increase for the readline buffer length in
85 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
86
876.04 Wed Aug 3 17:15:45 CEST 2011
88 - use even more efficient and more compatible condvars for
89 compatibility to AnyEvent 6.x :)
90 - more inconsequential ecb.h updates.
91
926.03 Wed Aug 3 11:41:30 CEST 2011
93 - change how Coro patches AnyEvent condvars for compatibility to
94 AnyEvent 6.x.
95 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
96 hasn't been included.
97
986.02 Wed Jul 13 04:35:19 CEST 2011
99 - "improve portability to Gentoo" - gentoo manages to put perl variables
100 in memory areas that are farther than 2gb apart, which the jit couldn't
101 handle and barfed. now it's just a bit slower on gentoo and similar
102 systems.
103
1046.01 Sun Jul 3 12:31:14 CEST 2011
105 - workarounds are good, but the test for whether pthreads are used
106 was not good. thisone should be better.
107 - check differently whether gcc generates cfi instructions itself.
108
1096.0 Wed Jun 29 19:43:35 CEST 2011
110 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
111 destroyed and cleaned up automatically (e.g. async { schedule }).
112 - implement a JIT compiler for part of the thread switch code,
113 which gives a 50% speed improvement on threaded perls, and
114 about 4% on non-thraeded perls (so threaded perls now finally
115 reach about half the speed of non-threaded perls).
116 - slightly modernise Coro::Intro, add section about rouse functions.
117 - avoid DEFSV and ERRSV, giving another 10% improvement
118 in thread switching.
119 - Coro::State->is_destroyed is now called is_zombie.
120 - implement a Coro->safe_cancel method that might fail, but
121 cancels in a "safer" way if it succeeds.
122 - add preliminary support for DEBUGGING perls.
123 - get rid of two hash-accesses when initialising a new Coro - this
124 speeds up coro creation by almost a factor of two.
125 - croak when a coro that is being cancelled tries to block
126 (e.g. while executing a guard block), instead of crashing or
127 deadlocking.
128 - use a more robust and also faster method to identify Coro::State
129 objects - speeds up everything a bit.
130 - implement Coro->cancel in XS for a 20% speed improvement, and to
131 be able to implement mutual cancellation.
132 - speed up context switches by a percent or two by more efficiently
133 allocating context stack entries.
134 - implement Coro->join and Coro->on_destroy in XS for a speedup and
135 a reduction in memory use.
136 - cancelling a coro while it itself is cancelling another coro is
137 now supported and working, instead of triggering an assertion.
138 - be a bit more crash-resistant when calling (buggy) on_destroy
139 callbacks (best effort).
140 - move on_destroy into the slf_frame, to allow extension slf
141 functions to have destructors.
142 - get rid if coro refcounting - simply crash in other interpreter
143 threads by nulling the pointers on clone.
144 - simplify warn/die hook handling when loading Coro - the convoluted
145 logic seems to be no longer neccessary.
146 - use libecb instead of our own home-grown gcc hacks.
147 - document alternatives to Coro::LWP. Please use them :)
148 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
149 sigaltstack. Really. wine suffers from it, erlang suffers from it,
150 and it's known since at least 2006.
151
1525.372 Wed Feb 23 06:14:30 CET 2011
153 - apparently mingw doesn't provide a working gettimeofday, try to
154 work around that by relying on Time::HiRes (indirectly brought to
155 my attention by Max Maischein).
156 - fix some portability issues when Time::HiRes was used.
157
1585.371 Mon Feb 21 14:36:08 CET 2011
159 - backport to windows process emulation code again.
160
1615.37 Sat Feb 19 07:49:44 CET 2011
162 - add a big "Coro thread life cycle" section to "man Coro".
163 - try a tentative workaround against the breakage that 5.13 has
164 introduced without depreciation period. sigh.
165 - no longer use Time::HiRes if gettimeofday is available, which
166 saves quite a lot of memory.
167
1685.36 Sun Feb 13 05:33:41 CET 2011
169 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
170 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
171 method call.
172 - undocument Coro::Timer::sleep and obsolete whole module.
173 - optimise Coro::Timer::timeout memory and cpu usage.
174 - slightly updated Coro::Intro for recent changes.
175 - do not initialise PL_dirty anymore.
176
1775.25 Thu Nov 11 01:08:39 CET 2010
178 - try a different approach on netbsd - netbsd 5 finally has marginally
179 working pthreads, but still broken ucontext/sigaltstack.
180 - openbsd 4.8 finally got their act together, Coro works out of the box
181 with asm, setjmp and pthreads (no change, just informational).
182
1835.24 Sat Oct 23 11:27:12 CEST 2010
184 - port to the EV 4.0 API.
185 - work around bugs in mingw32, making strawberry perl work
186 out of the box.
187 - correctly modify Coro::AIO function prototypes
188 so that they reflect the "no optional parameters" rule.
189 - "ported" libcoro to C++.
190
1915.23 Mon May 17 18:50:42 CEST 2010
192 - be more resistant to ordering changes when initialising
193 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
194 Waldorf).
195 - document that perl 5.12 deliberately removed support for cloning.
196
1975.22 Wed Apr 14 03:55:35 CEST 2010
198 - correctly return udnef on errors in Coro::Handle::read/write
199 (testcase by Marc Mims).
200 - convert Coro::Util into a "perl compatibility wrapper" - the functions
201 are less useful now, but are drop-in replacements for existing
202 functions, listing better alternatives in the documentation. This also
203 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
204 with Coro::Util::inet_aton.
205 - do not override $Coro::idle unconditionally in Coro.pm, as other
206 modules could have provided their own idle coro already
207 (for exmaple, Coro::AnyEvent).
208 - fix Coro::Util::gethost* functions.
209 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
210
2115.21 Wed Dec 16 07:19:51 CET 2009
212 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
213 together.
214 - add some examples on how to combine other event loops with Coro in
215 Coro::AnyEvent, and how to run it (and not to block). Seems to be
216 the most common source of confusion.
217 - try to catch people naively blocking in an event callback.
218 - work around the perl filehandle bug issue in conjunction with
219 older common::sense (as indirectly pointed out by ZSystem).
220 - clarify the "not from signal handlers" section.
221
2225.2 Sun Oct 4 14:54:24 CEST 2009
223 - Coro::Storable destroyed the prototypes of the functions it wrapped.
224 - export rouse_cb and rouse_wait by default now.
225 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
226 - new method $state->swap_sv.
227 - added section on "windows process emulation" to the manpage,
228 after a not-so-fruitful (nor-friendly) "discussion" with chip
229 salzenberg (discussion implies arguments, but his only arguments
230 were ad-hominems, one wonders why he started it in the first
231 place). I hope this explains it well enough for him to understand,
232 and maybe well enough for others to understand.
233 - use common::sense everywhere now.
234 - idle callbacks are no longer supported, use idle coros instead.
235 - print a thread listing when a deadlock is detected.
236
2375.17 Sat Aug 22 23:09:31 CEST 2009
238 - work around a bug in the perl debugger causing crashes
239 when running under the debugger by marking _pool_handler as nodebug.
240 - speed up Coro::async considerably.
241 - try some hacks to get netbsd to work "more often" - their broken
242 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
243 - convert Coro to AE 5.0 API.
244
2455.162 Tue Jul 28 04:04:03 CEST 2009
246 - perl 5.8.2 is now minimum requirement.
247 - skip t/19_handle.t on broken windows perls.
248
2495.161 Wed Jul 22 04:47:38 CEST 2009
250 - Coro::AnyEvent::poll could have a different prototype when EV was
251 used as backend (analyzed by Tatsuhiko Miyagawa).
252 - Coro::AnyEvent errornously initialised the event loop when loaded,
253 not on demand.
254 - try to workaround rare */t/01_unblock.t failures.
255
2565.16 Tue Jul 21 01:44:37 CEST 2009
257 - Coro::AnyEvent failed to hook into the event loop
258 when no threads had been readied between detecting
259 the event loop and actually running it.
260 - considerably speed up Coro::Select by taking avdantage
261 of AnyEvent > 4.8 and some other optimisations.
262 - implement paragraph readline mode in Coro::Handle
263 (based on patches by Zsbán Ambrus).
264 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
265 and analyzed by Yasuhiro MATSUMOTO).
266 - clarified libcoro license and copyright.
267 - someone stole my EXTRA_META!!!
268 - implement Coro::Select::patch_pp_sselect and it's brother,
269 for hardcode select overriding.
270
2715.151 Mon Jul 6 05:41:57 CEST 2009
272 - backport to windows process emulation code again (patch by
273 Yasuhiro MATSUMOTO).
274 - slightly update Coro::MakeMaker.
275
2765.15 Tue Jun 30 10:28:06 CEST 2009
277 - deprecate Coro::Socket, document how to get ipv6 support via
278 AnyEvent::Socket instead.
279 - implement signal->wait ($cb) interface, similar to semaphores.
280 - work around SvOK not supporting getmagic, so we have to getmagic
281 to test for undef :/ (reported by Matthias Waldorf).
282 - load Coro::AnyEvent in all modules using AnyEvent.
283 - work around perl corrupting our internal data structures,
284 reported by Tokuhiro Matsuno.
285 - enable per-coroutine real and cpu time gathering
286 (Coro::State::enable_times).
287
2885.14 Wed Jun 24 01:37:48 CEST 2009
289 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
290 as this seems to have been a difficult concept (poll, sleep, idle,
291 idle_upto).
292 - add Coro::AnyEvent::readable/writable functions.
293 - clarify Coro::EV/Event/AnyEvent manpages.
294 - free per-thread global scalars in the thread calling ->cancel, to
295 avoid crashes when $_, $@ etc., are magical but some of those
296 had already been freed.
297 - "unexperimentalise" the callback interface for Coro::Semaphore.
298 - speed up ready queue management/context switching by using a linked
299 list instead of an array (~5-10%).
300 - implement "watch" command in Coro::Debug shells.
301 - for fun, implement time-slicing as an example in the manpage.
302 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
303 Coro::Event, use the normal AnyEvent handling instead of dieing
304 (the same is true for Coro::Handle).
305 - properly document Coro::EV::timed_io_once.
306 - avoid unneccessary ->cancel calls in Coro::Handle.
307 - maybe make it work on mingw32 with win32 backend
308 (based on patch by Yasuhiro Matsumoto).
309
3105.132 Fri May 29 09:00:39 CEST 2009
311 - do not keep a reference to the argument itself in
312 Coro::Semaphore::guard, as it could change later.
313 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
314 should support a prepare callback.
315
3165.131 Mon Mar 16 23:20:37 CET 2009
317 - implement and document Coro->suspend, Coro->resume.
318 - fix Coro::Select implementation to not (often) close
319 the passed file descriptors (testcase provided by pippijn).
320
3215.13 Mon Dec 15 21:51:42 CET 2008
322 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
323 - don't set diehook to C<undef> but instead to NULL, to avoid
324 spurious warnings.
325 - fix a lot of bugs in Coro::SemaphoreSet.
326 - Coro::SemaphoreSet will less often create a semaphore needlessly.
327 - add Coro::SemaphoreSet::count and wait methods.
328 - take advantage of the new Guard module.
329 - deprecate Coro::guard.
330 - try to fix the dreaded 01_unblock tests once more. I hate it when
331 testsuites need more fixing than the code they are supposed to test.
332 - croak in more cases when a required callback isn't resolvable.
333 - fix some minor issues in Coro::State->call/eval.
334 - use current coroutine context instead of a temporary one
335 when temporarily switching to another coroutine.
336 - do not call C-level on_destroy handlers during global destruction,
337 to avoid needless segfaults.
338
3395.12 Sun Dec 7 13:30:38 CET 2008
340 - add default config for MirOS, which seems to be a bug-to-bug
341 compatible fork of openbsd ("world domination by releasing
342 openbsd cvs before the openbsd folks do it" or so :).
343 - free_padlist did destroy the names pad, not good, but didn't
344 seem to bother perl - this could fix issues such as eval ""
345 inside a function called from multiple coroutines.
346 - use a different method to detect destruction time.
347 - be more careful when freeing padlists just before global
348 destruction.
349 - fixed and expanded the call/cc example.
350 - renamed _terminate to _coro_run.
351 - new method Coro::Channel->shutdown.
352 - try pthreads on openbsd <4.4 (broken sigaltstack, will
353 pthreads fare better?).
354 - be less picky about destroying "a" running coroutine.
355
3565.11 Tue Nov 25 21:49:05 CET 2008
357 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
358 working code with failed assertions, introducing more bugs than
359 it fixes, requiring elaborate workarounds :(
360
3615.1 Mon Nov 24 08:54:59 CET 2008
362 - wrote a small introductory tutorial - Coro::Intro.
363 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
364 - Coro::Select did errornously dup the file descriptors
365 and didn't work with all AnyEvent backends.
366 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
367 LWP data transfers.
368 - disassociate c contexts from coro objects - this is agruably more
369 correct, but mostly allows sharing of cctxs between coro and state
370 objects, for added memory savings and speed increases.
371 - bumped $Coro::POOL_RSS up to 32kb by default.
372 - no longer set the optype to OP_CUSTOM, as B::* understandably
373 doesn't like this very much (and we *are* a type of entersub).
374 - implement state cloning, just to prove that call/cc can be done.
375 - automatically load Coro::AnyEvent in Coro::Handle.
376 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
377 do not have this method (and don't need it either).
378 - speed up generic anyevent methods in Coro::Handle by using rouse
379 callbacks.
380 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
381 others. It also makes the debugger happier, as you can trace
382 through the idle threads now.
383 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
384 - eg/event was pretty broken.
385 - better 5.8.6 compatibility.
386
3875.0 Thu Nov 20 10:35:05 CET 2008
388 - NEW ARCHITECTURE: use the latest 4.x version if you experience
389 stability issues.
390 - bump API version to 7 - all dependents must be recompiled.
391 - removed timed_* functions - they were not being used anyways
392 and should be replaced by a more generic mechanism -
393 and were annoying to support anyways :)
394 - removed SemaphoreSet's waiter method - use sem method instead.
395 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
396 - async_pool did free a scalar value twice
397 ("Attempt to unreference...").
398 - fix a longstanding bug where calling terminate on a coro that
399 was waiting for a semaphore that was just becoming available
400 would cause a deadlock (semaphore would get into a state where
401 it was available but waiters were still blocked).
402 - calling throw on a coroutine that is waiting for a semaphore will
403 no longer make it acquire the semaphore (and thus leak a count).
404 - perl's process emulation is now not even theoretically supported
405 anymore.
406 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
407 conversion of callback-style to blocking-style.
408 - new methods $coro->schedule_to and ->cede_to, to specifically
409 schedule or cede to a specific coroutine.
410 - new function Coro::Semaphore::wait.
411 - use named constants in Coro::Channel (Richard Hundt).
412 - directly patch the entersub opcode calling SLF functions (cede,
413 transfer and so on). this does speed up context switching, but
414 more importanly, it frees us from the hardcoded behaviour of
415 entersub, so we might actually be able to return something from
416 those functions and atcually create new ones.
417 - take advantage of __builtin_frame_address on gcc.
418 - expose THX in coroapi (not sure whether this was a wise decision,
419 as "threaded" perls are running at half speed anyways).
420 - implement execute_slf (schedule-like-function) interface that makes
421 it possible to implement schedule-like-functions in XS.
422 - use new SLF interface to massively speed up Coro::EV by roughly a
423 factor of two.
424 - used new SLF interface to massively speed up Coro::Semaphore by a
425 factor of three.
426 - used new SLF interface to speed up Coro::AIO by roughly a factor of
427 four and reduce its memory usage considerably.
428 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
429 for a nice speedup and vastly more correct behaviour. Also implement
430 a new method "sem" to get at the underlying semaphore object.
431 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
432 (in comparison) 20-40% speedup.
433 - used new SLF interface to reimplement Coro::Signal gaining
434 some unknown (because I was too lazy), but certain, speedup, and also
435 making signals reliable for the first time.
436 - used new SLF interface and other optimisations to speed up async_pool
437 by a factor of two. It also doesn't rely on perl's exception mechanism
438 to exit anymore. The overhead for terminating an async_pool, coro over
439 a normal async is now very small.
440 - sped up coroutine creation/destruction by 40%.
441 - forgot to include Coro/libcoro/README in the dist for all these years.
442 - work around a freebsd pthreads bug (manual testcancel is required as
443 pthread_cond_wait isn't a cancellation point on freebsd).
444 - use new rouse functions to speed up and simplify Coro::BDB.
445 - make "prefer perl native functions" work with threaded perls.

465
4664.91 Mon Nov 10 05:36:38 CET 2008
467 - the ->throw exception object no longer leaks.

472 instead of being ignored.
473 - ->throw is now supported on Coro::State objects.
474 - clean up cctx creation code a bit.
475 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
476
4774.9 Sat Nov 8 17:45:27 CET 2008
478 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
479 - (libcoro) no longer leak threads in the experimental pthread backend,
480 also speed it up considerably.
481 - (libcoro) do not rely on makecontext passing void *'s unscathed.

491 - tried to hack around openbsd bugs.
492
4934.804 Wed Nov 5 16:36:00 CET 2008
494 - Coro::Debug::new_unix_server would not create a non-blocking listening
495 socket, sometimes causing freezes.
496 - (libcoro) fix misaligned stack points for setjmp and assembly
497 methods, which can cause crashes on x86/x86_64 with a sufficiently
498 aggressive compiler.
499 - new function: Coro::Debug::new_tcp_server.
500 - move ->throw into the Coro class because it only works on coro objects.

520
5214.749 Mon Sep 29 14:40:12 CEST 2008

525 - implement, but do not document, PerlIO::cede(granularity).
526 - Coro::Storable forgot to wrap Storable::pstore.
527 - work around the multitude of leaks and memory corruption
528 bugs in PerlIO::via by using our own C-level perliol. As a side
529 effect, Coro::Storable is now much, much, much faster.
530
5314.747 Tue Sep 23 01:59:41 CEST 2008
532 - fix a per-cv memleak (one empty array was leaked per
533 code reference).

543
5444.745 Thu Jul 24 00:14:38 CEST 2008
545 - remove debugging code related to MgPV_nolen_const, also try to
546 make it compile with perl 5.8.6 (yes, apple apparently loves
547 outdated software). Reported by John S.
548
5494.744 Tue Jul 8 22:06:35 CEST 2008
550 - correctly provide default DIE/WARN handlers as documented.
551 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
552 implementations inside perl work fine for us.
553
5544.743 Mon Jun 16 00:21:57 CEST 2008
555 - when using Coro::EV without running EV::loop it could
556 result in busy-waiting for events, this has been fixed.

558
5594.742 Sat May 31 14:10:21 CEST 2008

561 - require EV 3.3+.
562
5634.741 Fri May 30 23:33:09 CEST 2008
564 - tell netbsd how utterly broken their imitation of an OS is
565 and refuse to build by default if pthreads are in use.
566 - switch to "s" method on all bsd's by default, as their ucontext
567 stuff seems just too broken.
568 - fix a bug in Coro::Select.
569
5704.74 Thu May 29 20:05:31 CEST 2008
571 - do not test Coro::LWP for lack of dependencies.
572 - do not test Coro::Select for lack of working perls.
573
5744.73 Thu May 29 2008
575 - fix a bug in Coro::EV which would cause it to block despite
576 there being runnable coroutines.
577 - sprinkle "no warnings" freely over everything, also suppress
578 warnings for some other modules.
579 - fix typo in WSAEWOULDBLOCK.
580
5814.72 Sun May 25 05:14:36 CEST 2008
582 - tweak META.yaml a bit, unfortunately, there is no documented way
583 to have optional dependencies with CPAN. doh :(
584 - avoid running some tests on windows because they would fail due to
585 perl bug (broken fork, broken pipes...).
586 - work around perl on windows bugs where perl returns undocumented
587 error codes for sysread, syswrite etc. by taking advantage
588 of AnyEvent's workaround for that problem.
589 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
590 a common perl implementation bug on windows.
591 - use unix domain sockets in testsuite to work around
592 common perl implementation bugs on widows (they are emulated by
593 tcp sockets on windows. ugh.)
594
5954.71 Sat May 24 20:01:27 CEST 2008
596 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
597 - take advantage of async name resolution of AnyEvent::Util.
598 - work around brutal inet_aton override in Coro::LWP.
599 - take advantage of the readyhook in Coro::EV, for smoother
600 scheduling.
601

603 - completely reworked the Coro manpage.
604 - added Coro::AnyEvent, generic event loop integration.
605 - implement cancel, ready and kill commands in Coro::Debug.
606 - document find_coro in Coro::Debug.
607 - incompatible change: rename has_stack to has_cctx.
608 - Coro::AIO and Coro::BDB no longer force event model detection,
609 use AnyEvent::AIO and AnyEvent::BDB.

84.6 Sat Apr 26 10:05:14 CEST 2008 6114.6 Sat Apr 26 10:05:14 CEST 2008
9 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported 612 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
10 by the Coro module. It was a mistake to have it in the first place. 613 by the Coro module. It was a mistake to have it in the first place.
11 - (experimental) support for activestate perl 5.10 (method "w"). 614 - (experimental) support for activestate perl 5.10 (method "w").
