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)). 6TODO: swap_sv, maybe add scope_swap_sv, andallow to unswap by repeat?
7TODO: swap_sv not undone in pool
7 8
9TODO: warnhook reports from wrong line number now, when arg is Math::GMP number.
10 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess
11 to report a full stacktrace, which should help find out
12 where the actual call is.
13 - disable ecb.h libm dependency, to compile on ancient systems
14 or under adverse conditions.
15
166.33 Mon Nov 18 11:26:27 CET 2013
17 - do not crash when freeing padlists with holes (in 5.18).
18 - tentative SVt_BIND 5.19 port/fix.
19
206.32 Tue Nov 5 15:35:35 CET 2013
21 - use a new algorithm to derive padlists for perl 5.18. The old
22 one could lead to 0-pointer accesses inside perl (reported
23 by Darin McBride).
24
256.31 Thu May 9 07:39:48 CEST 2013
26 - Coro::AIO requests would crash if the thread was ready'd
27 while the request was ongoing.
28
296.29 Wed May 8 02:55:18 CEST 2013
30 - when an on_destroy handler destructs the coro currently being
31 destructed a perl scalar could be accessed after being freed,
32 likely causing a crash.
33
346.28 Wed Mar 6 06:58:02 CET 2013
35 - clean remnants of existing __DIE__ and __WARN__ handlers so
36 they lose their magic and will not cause segfaults later
37 (testcase by Andrey Sagulin).
38 - improved Coro::State documentation a bit.
39 - Coro::Debug::command now flushes the output.
40 - add hack detection code for x32 abi, because the braindead slugs
41 who designed that made it look exactly like x86_64 without
42 providing proper compile time symbols to test for it. as a result,
43 this detection cannot work reliably.
44 - valgrind stack registering was broken.
45 - do not rely on Time::HiRes anymore in Coro::Debug.
46
476.23 Fri Dec 7 23:36:37 CET 2012
48 - use experimental fiber implementation on native windows
49 perls.
50 - use sizeof (void *) as multiplication factor for stack sizes,
51 to accomodate the totally braindamaged microsoft 64 bit "os".
52 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
53 activeperl 5.16 crashes when PerlIO_define_layer is called due
54 to some bug in the perl dll, strawberry perl at least passes
55 the testsuite.
56 - implement Coro::Handle->peeraddr/host/port, for slightly
57 improved compatibility with LWP.
58 - implement 5.17 compatibility by almost blindly applying a
59 good-looking patch by Father Chrysostomos.
60 - move stack management functions into libcoro 3.
61 - libcoro version 3 "released".
62 - support magic values as timed_io_once args.
63 - recommend AnyEvent 7+ or EV 4+, also require EV
64 version 4 or newer for Coro::EV.
65
666.10 Tue Oct 9 01:14:27 CEST 2012
67 - updated ecb.h, it had a typo that caused it to not compile on many
68 big endian systems (reported by many people).
69 - disable memory fences in ecb.h to improve portability.
70
716.09 Sat Oct 6 23:25:02 CEST 2012
72 - Coro::EV I/O watchers were not interruptible by exceptions
73 (Coro::State::throw) (testcase by sten).
74 - ->throw now puts threads into the ready queue, as this seems to
75 be expected by existing code, and code that doesn't cope with spurious
76 wakeups needs fixing anyway.
77 - use fd -1 in mmap.
78 - cast I32 to int in error message printf.
79 - warn about broken so-called "hardened" kernels.
80
816.08 Fri Apr 13 12:05:47 CEST 2012
82 - be more aggressive about exiting like perl does - formerly,
83 exiting from the non-main thread would not execute END blocks.
84
856.07 Fri Nov 11 21:21:48 CET 2011
86 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
87 - update ecb.h.
88
896.06 Mon Aug 8 23:59:48 CEST 2011
90 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
91 backend, which is an order of magnitude slower. unfortunately, cygwins
92 pthread implementation isn't very complete either, so allocate the stack
93 twice just to be sure.
94 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
95 in its ithreaded perl - best recompile cygwin and use the 'w'indows
96 backend for much better performance. also disable ithreads for
97 even better performance...).
98
996.05 Thu Aug 4 21:36:36 CEST 2011
100 - blush, condvar values would not be propagated from send to recv anymore
101 (reported by Chip Salzenberg).
102 - use exponential increase for the readline buffer length in
103 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
104
1056.04 Wed Aug 3 17:15:45 CEST 2011
106 - use even more efficient and more compatible condvars for
107 compatibility to AnyEvent 6.x :)
108 - more inconsequential ecb.h updates.
109
1106.03 Wed Aug 3 11:41:30 CEST 2011
111 - change how Coro patches AnyEvent condvars for compatibility to
112 AnyEvent 6.x.
113 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
114 hasn't been included.
115
1166.02 Wed Jul 13 04:35:19 CEST 2011
117 - "improve portability to Gentoo" - gentoo manages to put perl variables
118 in memory areas that are farther than 2gb apart, which the jit couldn't
119 handle and barfed. now it's just a bit slower on gentoo and similar
120 systems.
121
1226.01 Sun Jul 3 12:31:14 CEST 2011
123 - workarounds are good, but the test for whether pthreads are used
124 was not good. thisone should be better.
125 - check differently whether gcc generates cfi instructions itself.
126
1276.0 Wed Jun 29 19:43:35 CEST 2011
128 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
129 destroyed and cleaned up automatically (e.g. async { schedule }).
130 - implement a JIT compiler for part of the thread switch code,
131 which gives a 50% speed improvement on threaded perls, and
132 about 4% on non-thraeded perls (so threaded perls now finally
133 reach about half the speed of non-threaded perls).
134 - slightly modernise Coro::Intro, add section about rouse functions.
135 - avoid DEFSV and ERRSV, giving another 10% improvement
136 in thread switching.
137 - Coro::State->is_destroyed is now called is_zombie.
138 - implement a Coro->safe_cancel method that might fail, but
139 cancels in a "safer" way if it succeeds.
140 - add preliminary support for DEBUGGING perls.
141 - get rid of two hash-accesses when initialising a new Coro - this
142 speeds up coro creation by almost a factor of two.
143 - croak when a coro that is being cancelled tries to block
144 (e.g. while executing a guard block), instead of crashing or
145 deadlocking.
146 - use a more robust and also faster method to identify Coro::State
147 objects - speeds up everything a bit.
148 - implement Coro->cancel in XS for a 20% speed improvement, and to
149 be able to implement mutual cancellation.
150 - speed up context switches by a percent or two by more efficiently
151 allocating context stack entries.
152 - implement Coro->join and Coro->on_destroy in XS for a speedup and
153 a reduction in memory use.
154 - cancelling a coro while it itself is cancelling another coro is
155 now supported and working, instead of triggering an assertion.
156 - be a bit more crash-resistant when calling (buggy) on_destroy
157 callbacks (best effort).
158 - move on_destroy into the slf_frame, to allow extension slf
159 functions to have destructors.
160 - get rid if coro refcounting - simply crash in other interpreter
161 threads by nulling the pointers on clone.
162 - simplify warn/die hook handling when loading Coro - the convoluted
163 logic seems to be no longer neccessary.
164 - use libecb instead of our own home-grown gcc hacks.
165 - document alternatives to Coro::LWP. Please use them :)
166 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
167 sigaltstack. Really. wine suffers from it, erlang suffers from it,
168 and it's known since at least 2006.
169
1705.372 Wed Feb 23 06:14:30 CET 2011
171 - apparently mingw doesn't provide a working gettimeofday, try to
172 work around that by relying on Time::HiRes (indirectly brought to
173 my attention by Max Maischein).
174 - fix some portability issues when Time::HiRes was used.
175
1765.371 Mon Feb 21 14:36:08 CET 2011
177 - backport to windows process emulation code again.
178
1795.37 Sat Feb 19 07:49:44 CET 2011
180 - add a big "Coro thread life cycle" section to "man Coro".
181 - try a tentative workaround against the breakage that 5.13 has
182 introduced without depreciation period. sigh.
183 - no longer use Time::HiRes if gettimeofday is available, which
184 saves quite a lot of memory.
185
1865.36 Sun Feb 13 05:33:41 CET 2011
187 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
188 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
189 method call.
190 - undocument Coro::Timer::sleep and obsolete whole module.
191 - optimise Coro::Timer::timeout memory and cpu usage.
192 - slightly updated Coro::Intro for recent changes.
193 - do not initialise PL_dirty anymore.
194
1955.25 Thu Nov 11 01:08:39 CET 2010
196 - try a different approach on netbsd - netbsd 5 finally has marginally
197 working pthreads, but still broken ucontext/sigaltstack.
198 - openbsd 4.8 finally got their act together, Coro works out of the box
199 with asm, setjmp and pthreads (no change, just informational).
200
2015.24 Sat Oct 23 11:27:12 CEST 2010
202 - port to the EV 4.0 API.
203 - work around bugs in mingw32, making strawberry perl work
204 out of the box.
205 - correctly modify Coro::AIO function prototypes
206 so that they reflect the "no optional parameters" rule.
207 - "ported" libcoro to C++.
208
2095.23 Mon May 17 18:50:42 CEST 2010
210 - be more resistant to ordering changes when initialising
211 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
212 Waldorf).
213 - document that perl 5.12 deliberately removed support for cloning.
214
2155.22 Wed Apr 14 03:55:35 CEST 2010
216 - correctly return udnef on errors in Coro::Handle::read/write
217 (testcase by Marc Mims).
218 - convert Coro::Util into a "perl compatibility wrapper" - the functions
219 are less useful now, but are drop-in replacements for existing
220 functions, listing better alternatives in the documentation. This also
221 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
222 with Coro::Util::inet_aton.
223 - do not override $Coro::idle unconditionally in Coro.pm, as other
224 modules could have provided their own idle coro already
225 (for exmaple, Coro::AnyEvent).
226 - fix Coro::Util::gethost* functions.
227 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
228
2295.21 Wed Dec 16 07:19:51 CET 2009
230 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
231 together.
232 - add some examples on how to combine other event loops with Coro in
233 Coro::AnyEvent, and how to run it (and not to block). Seems to be
234 the most common source of confusion.
235 - try to catch people naively blocking in an event callback.
236 - work around the perl filehandle bug issue in conjunction with
237 older common::sense (as indirectly pointed out by ZSystem).
238 - clarify the "not from signal handlers" section.
239
2405.2 Sun Oct 4 14:54:24 CEST 2009
241 - Coro::Storable destroyed the prototypes of the functions it wrapped.
242 - export rouse_cb and rouse_wait by default now.
243 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
244 - new method $state->swap_sv.
245 - added section on "windows process emulation" to the manpage,
246 after a not-so-fruitful (nor-friendly) "discussion" with chip
247 salzenberg (discussion implies arguments, but his only arguments
248 were ad-hominems, one wonders why he started it in the first
249 place). I hope this explains it well enough for him to understand,
250 and maybe well enough for others to understand.
251 - use common::sense everywhere now.
252 - idle callbacks are no longer supported, use idle coros instead.
253 - print a thread listing when a deadlock is detected.
254
2555.17 Sat Aug 22 23:09:31 CEST 2009
256 - work around a bug in the perl debugger causing crashes
257 when running under the debugger by marking _pool_handler as nodebug.
258 - speed up Coro::async considerably.
259 - try some hacks to get netbsd to work "more often" - their broken
260 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
261 - convert Coro to AE 5.0 API.
262
2635.162 Tue Jul 28 04:04:03 CEST 2009
264 - perl 5.8.2 is now minimum requirement.
265 - skip t/19_handle.t on broken windows perls.
266
2675.161 Wed Jul 22 04:47:38 CEST 2009
268 - Coro::AnyEvent::poll could have a different prototype when EV was
269 used as backend (analyzed by Tatsuhiko Miyagawa).
270 - Coro::AnyEvent errornously initialised the event loop when loaded,
271 not on demand.
272 - try to workaround rare */t/01_unblock.t failures.
273
2745.16 Tue Jul 21 01:44:37 CEST 2009
275 - Coro::AnyEvent failed to hook into the event loop
276 when no threads had been readied between detecting
277 the event loop and actually running it.
278 - considerably speed up Coro::Select by taking avdantage
279 of AnyEvent > 4.8 and some other optimisations.
280 - implement paragraph readline mode in Coro::Handle
281 (based on patches by Zsbán Ambrus).
282 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
283 and analyzed by Yasuhiro MATSUMOTO).
284 - clarified libcoro license and copyright.
285 - someone stole my EXTRA_META!!!
286 - implement Coro::Select::patch_pp_sselect and it's brother,
287 for hardcode select overriding.
288
2895.151 Mon Jul 6 05:41:57 CEST 2009
290 - backport to windows process emulation code again (patch by
291 Yasuhiro MATSUMOTO).
292 - slightly update Coro::MakeMaker.
293
2945.15 Tue Jun 30 10:28:06 CEST 2009
295 - deprecate Coro::Socket, document how to get ipv6 support via
296 AnyEvent::Socket instead.
297 - implement signal->wait ($cb) interface, similar to semaphores.
298 - work around SvOK not supporting getmagic, so we have to getmagic
299 to test for undef :/ (reported by Matthias Waldorf).
300 - load Coro::AnyEvent in all modules using AnyEvent.
301 - work around perl corrupting our internal data structures,
302 reported by Tokuhiro Matsuno.
303 - enable per-coroutine real and cpu time gathering
304 (Coro::State::enable_times).
305
3065.14 Wed Jun 24 01:37:48 CEST 2009
307 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
308 as this seems to have been a difficult concept (poll, sleep, idle,
309 idle_upto).
310 - add Coro::AnyEvent::readable/writable functions.
311 - clarify Coro::EV/Event/AnyEvent manpages.
312 - free per-thread global scalars in the thread calling ->cancel, to
313 avoid crashes when $_, $@ etc., are magical but some of those
314 had already been freed.
315 - "unexperimentalise" the callback interface for Coro::Semaphore.
316 - speed up ready queue management/context switching by using a linked
317 list instead of an array (~5-10%).
318 - implement "watch" command in Coro::Debug shells.
319 - for fun, implement time-slicing as an example in the manpage.
320 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
321 Coro::Event, use the normal AnyEvent handling instead of dieing
322 (the same is true for Coro::Handle).
323 - properly document Coro::EV::timed_io_once.
324 - avoid unneccessary ->cancel calls in Coro::Handle.
325 - maybe make it work on mingw32 with win32 backend
326 (based on patch by Yasuhiro Matsumoto).
327
3285.132 Fri May 29 09:00:39 CEST 2009
329 - do not keep a reference to the argument itself in
330 Coro::Semaphore::guard, as it could change later.
331 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
332 should support a prepare callback.
333
3345.131 Mon Mar 16 23:20:37 CET 2009
335 - implement and document Coro->suspend, Coro->resume.
336 - fix Coro::Select implementation to not (often) close
337 the passed file descriptors (testcase provided by pippijn).
338
3395.13 Mon Dec 15 21:51:42 CET 2008
340 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
341 - don't set diehook to C<undef> but instead to NULL, to avoid
342 spurious warnings.
343 - fix a lot of bugs in Coro::SemaphoreSet.
344 - Coro::SemaphoreSet will less often create a semaphore needlessly.
345 - add Coro::SemaphoreSet::count and wait methods.
346 - take advantage of the new Guard module.
347 - deprecate Coro::guard.
348 - try to fix the dreaded 01_unblock tests once more. I hate it when
349 testsuites need more fixing than the code they are supposed to test.
350 - croak in more cases when a required callback isn't resolvable.
351 - fix some minor issues in Coro::State->call/eval.
352 - use current coroutine context instead of a temporary one
353 when temporarily switching to another coroutine.
354 - do not call C-level on_destroy handlers during global destruction,
355 to avoid needless segfaults.
356
3575.12 Sun Dec 7 13:30:38 CET 2008
358 - add default config for MirOS, which seems to be a bug-to-bug
359 compatible fork of openbsd ("world domination by releasing
360 openbsd cvs before the openbsd folks do it" or so :).
361 - free_padlist did destroy the names pad, not good, but didn't
362 seem to bother perl - this could fix issues such as eval ""
363 inside a function called from multiple coroutines.
364 - use a different method to detect destruction time.
365 - be more careful when freeing padlists just before global
366 destruction.
367 - fixed and expanded the call/cc example.
368 - renamed _terminate to _coro_run.
369 - new method Coro::Channel->shutdown.
370 - try pthreads on openbsd <4.4 (broken sigaltstack, will
371 pthreads fare better?).
372 - be less picky about destroying "a" running coroutine.
373
3745.11 Tue Nov 25 21:49:05 CET 2008
375 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
376 working code with failed assertions, introducing more bugs than
377 it fixes, requiring elaborate workarounds :(
378
3795.1 Mon Nov 24 08:54:59 CET 2008
380 - wrote a small introductory tutorial - Coro::Intro.
381 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
382 - Coro::Select did errornously dup the file descriptors
383 and didn't work with all AnyEvent backends.
384 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
385 LWP data transfers.
386 - disassociate c contexts from coro objects - this is agruably more
387 correct, but mostly allows sharing of cctxs between coro and state
388 objects, for added memory savings and speed increases.
389 - bumped $Coro::POOL_RSS up to 32kb by default.
390 - no longer set the optype to OP_CUSTOM, as B::* understandably
391 doesn't like this very much (and we *are* a type of entersub).
392 - implement state cloning, just to prove that call/cc can be done.
393 - automatically load Coro::AnyEvent in Coro::Handle.
394 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
395 do not have this method (and don't need it either).
396 - speed up generic anyevent methods in Coro::Handle by using rouse
397 callbacks.
398 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
399 others. It also makes the debugger happier, as you can trace
400 through the idle threads now.
401 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
402 - eg/event was pretty broken.
403 - better 5.8.6 compatibility.
404
4055.0 Thu Nov 20 10:35:05 CET 2008
406 - NEW ARCHITECTURE: use the latest 4.x version if you experience
407 stability issues.
408 - bump API version to 7 - all dependents must be recompiled.
409 - removed timed_* functions - they were not being used anyways
410 and should be replaced by a more generic mechanism -
411 and were annoying to support anyways :)
412 - removed SemaphoreSet's waiter method - use sem method instead.
413 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
414 - async_pool did free a scalar value twice
415 ("Attempt to unreference...").
416 - fix a longstanding bug where calling terminate on a coro that
417 was waiting for a semaphore that was just becoming available
418 would cause a deadlock (semaphore would get into a state where
419 it was available but waiters were still blocked).
420 - calling throw on a coroutine that is waiting for a semaphore will
421 no longer make it acquire the semaphore (and thus leak a count).
422 - perl's process emulation is now not even theoretically supported
423 anymore.
424 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
425 conversion of callback-style to blocking-style.
426 - new methods $coro->schedule_to and ->cede_to, to specifically
427 schedule or cede to a specific coroutine.
428 - new function Coro::Semaphore::wait.
429 - use named constants in Coro::Channel (Richard Hundt).
430 - directly patch the entersub opcode calling SLF functions (cede,
431 transfer and so on). this does speed up context switching, but
432 more importanly, it frees us from the hardcoded behaviour of
433 entersub, so we might actually be able to return something from
434 those functions and atcually create new ones.
435 - take advantage of __builtin_frame_address on gcc.
436 - expose THX in coroapi (not sure whether this was a wise decision,
437 as "threaded" perls are running at half speed anyways).
438 - implement execute_slf (schedule-like-function) interface that makes
439 it possible to implement schedule-like-functions in XS.
440 - use new SLF interface to massively speed up Coro::EV by roughly a
441 factor of two.
442 - used new SLF interface to massively speed up Coro::Semaphore by a
443 factor of three.
444 - used new SLF interface to speed up Coro::AIO by roughly a factor of
445 four and reduce its memory usage considerably.
446 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
447 for a nice speedup and vastly more correct behaviour. Also implement
448 a new method "sem" to get at the underlying semaphore object.
449 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
450 (in comparison) 20-40% speedup.
451 - used new SLF interface to reimplement Coro::Signal gaining
452 some unknown (because I was too lazy), but certain, speedup, and also
453 making signals reliable for the first time.
454 - used new SLF interface and other optimisations to speed up async_pool
455 by a factor of two. It also doesn't rely on perl's exception mechanism
456 to exit anymore. The overhead for terminating an async_pool, coro over
457 a normal async is now very small.
458 - sped up coroutine creation/destruction by 40%.
459 - forgot to include Coro/libcoro/README in the dist for all these years.
460 - work around a freebsd pthreads bug (manual testcancel is required as
461 pthread_cond_wait isn't a cancellation point on freebsd).
462 - use new rouse functions to speed up and simplify Coro::BDB.
463 - make "prefer perl native functions" work with threaded perls.
464 - condense Coro::Debug ps output, hint at v and w flags.
465 - (libcoro) lots of minor cleanups and portability improvements.
466
4674.914 Wed Nov 19 12:54:18 CET 2008
468 - fix a disastrous bug in the readline optimisation
469 introduced in 4.801.
470
4714.913 Sat Nov 15 07:58:28 CET 2008
472 - async_pool did free a scalar value twice
473 ("Attempt to unreference...").
474
4754.912 Thu Nov 13 18:31:23 CET 2008
476 - minor cleanups.
477 - use much larger stacks on linux and perl < 5.8.8.
478 - Coro::Debug::new_unix_server did not unlink the socket
479 when destroyed.
480
4814.911 Tue Nov 11 04:26:17 CET 2008
482 - "port" to threaded perls.
483
4844.91 Mon Nov 10 05:36:38 CET 2008
485 - the ->throw exception object no longer leaks.
486 - creating a new cctx leaked a scopestack entry (memleak).
487 - new coroutines didn't get created with a zero flags field
488 (unknown impact).
489 - calling ->throw on a not-yet-started coroutine should now work
490 instead of being ignored.
491 - ->throw is now supported on Coro::State objects.
492 - clean up cctx creation code a bit.
493 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
494
4954.9 Sat Nov 8 17:45:27 CET 2008
496 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
497 - (libcoro) no longer leak threads in the experimental pthread backend,
498 also speed it up considerably.
499 - (libcoro) do not rely on makecontext passing void *'s unscathed.
500 - fix compiletime dependencies on libcoro in the Makefile.
501 - cctx_count wasn't always updated properly.
502 - Coro::State::cctx_stacksize wasn't applied correctly.
503 - new function Coro::State::cctx_max_idle.
504 - the default max number of idle C contexts is now 4.
505 - (libcoro) try harder to get _setjmp/_longjmp.
506 - (libcoro) cleanup and extend the libcoro API to officially
507 allow the creation of empty source contexts.
508 - very experimental workaround for the totally broken netbsd platform.
509 - tried to hack around openbsd bugs.
510
5114.804 Wed Nov 5 16:36:00 CET 2008
512 - Coro::Debug::new_unix_server would not create a non-blocking listening
513 socket, sometimes causing freezes.
514 - (libcoro) fix misaligned stack points for setjmp and assembly
515 methods, which can cause crashes on x86/x86_64 with a sufficiently
516 aggressive compiler.
517 - new function: Coro::Debug::new_tcp_server.
518 - move ->throw into the Coro class because it only works on coro objects.
519
5204.803 Mon Nov 3 17:16:12 CET 2008
521 - (libcoro) use a global asm statement to become independent of gcc
522 otpimisations for CORO_ASM (thanks to pippijn for the idea).
523 - try to workaround yet another broken bsd, this time dragonfly.
524
5254.802 Thu Oct 30 10:56:12 CET 2008
526 - support -fno-omit-frame-pointer on x86 with the assembly method.
527 - tune 01_unblock.t tests a bit.
528
5294.801 Wed Oct 22 18:33:37 CEST 2008
530 - improve readline speed for very long "lines".
531 - backport to 5.8.8.
532
5334.8 Thu Oct 2 13:34:40 CEST 2008
534 - new function Coro::AIO::aio_wait.
535 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
536 - greatly speed up and reduce memory usage of Coro::AIO requests.
537 - implement some other µ-optimisations.
538
5394.749 Mon Sep 29 14:40:12 CEST 2008
540 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
541
5424.748 Sat Sep 27 14:03:19 CEST 2008
543 - implement, but do not document, PerlIO::cede(granularity).
544 - Coro::Storable forgot to wrap Storable::pstore.
545 - work around the multitude of leaks and memory corruption
546 bugs in PerlIO::via by using our own C-level perliol. As a side
547 effect, Coro::Storable is now much, much, much faster.
548
5494.747 Tue Sep 23 01:59:41 CEST 2008
550 - fix a per-cv memleak (one empty array was leaked per
551 code reference).
552 - avoid a crash in coro->call|rss when the coroutine was already
553 destroyed (most noticably when using Coro::Debug::ps :)
554 - also protect *Storable::FILE.
555 - push up default storable granularity to 20ms.
556
5574.746 Sun Sep 21 03:22:20 CEST 2008
558 - be more insistent on locking Storable against reentrancy
559 in Coro::Storable.
560 - move swap_def?v and throw to Coro::State, as documented.
561
5624.745 Thu Jul 24 00:14:38 CEST 2008
563 - remove debugging code related to MgPV_nolen_const, also try to
564 make it compile with perl 5.8.6 (yes, apple apparently loves
565 outdated software). Reported by John S.
566
5674.744 Tue Jul 8 22:06:35 CEST 2008
568 - correctly provide default DIE/WARN handlers as documented.
569 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
570 implementations inside perl work fine for us.
571
5724.743 Mon Jun 16 00:21:57 CEST 2008
573 - when using Coro::EV without running EV::loop it could
574 result in busy-waiting for events, this has been fixed.
575 - reduce codesize and improve performance by using EV_DEFAULT_UC.
576
5774.742 Sat May 31 14:10:21 CEST 2008

579 - require EV 3.3+.
580
5814.741 Fri May 30 23:33:09 CEST 2008
582 - tell netbsd how utterly broken their imitation of an OS is
583 and refuse to build by default if pthreads are in use.
584 - switch to "s" method on all bsd's by default, as their ucontext
585 stuff seems just too broken.
586 - fix a bug in Coro::Select.
587
5884.74 Thu May 29 20:05:31 CEST 2008
589 - do not test Coro::LWP for lack of dependencies.
590 - do not test Coro::Select for lack of working perls.
591
5924.73 Thu May 29 2008
593 - fix a bug in Coro::EV which would cause it to block despite
594 there being runnable coroutines.
595 - sprinkle "no warnings" freely over everything, also suppress
596 warnings for some other modules.
597 - fix typo in WSAEWOULDBLOCK.
598
5994.72 Sun May 25 05:14:36 CEST 2008
600 - tweak META.yaml a bit, unfortunately, there is no documented way
601 to have optional dependencies with CPAN. doh :(
8 - avoid running some tests on windows because they would fail due to 602 - avoid running some tests on windows because they would fail due to
