135.0 15
166.48 Sun Oct 4 19:03:51 CEST 2015
17 - fix memory leak when Coro::Handle uses Coro::EV internally
18 (testcase by Sten Sten).
19 - update code to libev 4 API (internally, Coro still used the
20 version 3 API calls).
21 - remove unused hv_sig.
22
236.47 Sat Jul 11 03:58:20 CEST 2015
24 - swap_svs - NVs can be in the SV head beginning with 5.20.
25
266.46 Tue Jun 30 14:36:30 CEST 2015
27 - restore portability to perls with windows fork emulation
28 (patch by Petr Písař).
29
306.45 Tue Jun 30 01:40:08 CEST 2015
31 - restore portability to perl 5.16 and below.
32
336.44 Tue Jun 30 00:41:54 CEST 2015
34 - avoid segfaulting (or worse) when tracing a canceled thread.
35 - the Event module silently broke it's public hook API, causing
36 failures on perls compiled with -Duselongdouble. Requiring
37 the latest version of Event because I don't know which release
38 changed this (it's not mentioned in the ChangeLog).
39 - allow xs level enterleave hooks via CoroAPI.
40
416.43 Thu Jun 4 15:38:14 CEST 2015
42 - use stability canary.
43 - port to stableperl-5.22.0-1.001.
44 - update libecb.
45
466.42 Wed Feb 11 20:29:52 CET 2015
47 - Coro::SemaphoreSet->try did not actually work (analyzed by
48 SATO Kentaro).
49 - upgrade libecb to be C11 compliant.
50
516.41 Sat Sep 6 22:08:46 CEST 2014
52 - restore portability to perl 5.8.x.
53 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
54 up some memory, but fixes "use feature" and similar modules
55 when used inside a Coro.
56 - allow zero as argument to Coro::Channel to mean the same thing
57 as no argument. this works with older versions as well,
58 but wasn't legal until now.
59 - slightly better c header file detection.
60
616.39 Mon Jun 2 00:00:08 CEST 2014
62 - work around more incompatible changes in 5.20.
63
646.38 Sun Jun 1 21:54:23 CEST 2014
65 - check that perl slots actually have enough space to hold
66 interpreter variables.
67 - untested port to perl 5.19 (64 bit tmps indices) (reported
68 by Andreas König).
69 - croak when cancel is called without a thread context.
70
716.37 Tue Mar 4 13:27:33 CET 2014
72 - *sigh*, removed leftover debugging code from debugging a
73 perl bug, of all things.
74
756.36 Tue Mar 4 07:11:59 CET 2014
76 - semaphores would not clear the destroy hook when interrupted
77 by ->throw, causing segfaults or worse.
78 - ->throw on a thread waiting for a semaphore did not acquire
79 the semaphore, but also didn't wake up other waiters,
80 possibly causing a deadlock.
81 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
82 to report a full stacktrace, which should help find out
83 where the actual call is.
84 - "atomically" destroy data in slf_destroy, because it is
85 the right thing to do, just in case.
86 - disable ecb.h libm dependency, to compile on ancient systems
87 or under adverse conditions.
88
896.33 Mon Nov 18 11:26:27 CET 2013
90 - do not crash when freeing padlists with holes (in 5.18).
91 - tentative SVt_BIND 5.19 port/fix.
92
936.32 Tue Nov 5 15:35:35 CET 2013
94 - use a new algorithm to derive padlists for perl 5.18. The old
95 one could lead to 0-pointer accesses inside perl (reported
96 by Darin McBride).
97
986.31 Thu May 9 07:39:48 CEST 2013
99 - Coro::AIO requests would crash if the thread was ready'd
100 while the request was ongoing.
101
1026.29 Wed May 8 02:55:18 CEST 2013
103 - when an on_destroy handler destructs the coro currently being
104 destructed a perl scalar could be accessed after being freed,
105 likely causing a crash.
106
1076.28 Wed Mar 6 06:58:02 CET 2013
108 - clean remnants of existing __DIE__ and __WARN__ handlers so
109 they lose their magic and will not cause segfaults later
110 (testcase by Andrey Sagulin).
111 - improved Coro::State documentation a bit.
112 - Coro::Debug::command now flushes the output.
113 - add hack detection code for x32 abi, because the braindead slugs
114 who designed that made it look exactly like x86_64 without
115 providing proper compile time symbols to test for it. as a result,
116 this detection cannot work reliably.
117 - valgrind stack registering was broken.
118 - do not rely on Time::HiRes anymore in Coro::Debug.
119
1206.23 Fri Dec 7 23:36:37 CET 2012
121 - use experimental fiber implementation on native windows
122 perls.
123 - use sizeof (void *) as multiplication factor for stack sizes,
124 to accomodate the totally braindamaged microsoft 64 bit "os".
125 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
126 activeperl 5.16 crashes when PerlIO_define_layer is called due
127 to some bug in the perl dll, strawberry perl at least passes
128 the testsuite.
129 - implement Coro::Handle->peeraddr/host/port, for slightly
130 improved compatibility with LWP.
131 - implement 5.17 compatibility by almost blindly applying a
132 good-looking patch by Father Chrysostomos.
133 - move stack management functions into libcoro 3.
134 - libcoro version 3 "released".
135 - support magic values as timed_io_once args.
136 - recommend AnyEvent 7+ or EV 4+, also require EV
137 version 4 or newer for Coro::EV.
138
1396.10 Tue Oct 9 01:14:27 CEST 2012
140 - updated ecb.h, it had a typo that caused it to not compile on many
141 big endian systems (reported by many people).
142 - disable memory fences in ecb.h to improve portability.
143
1446.09 Sat Oct 6 23:25:02 CEST 2012
145 - Coro::EV I/O watchers were not interruptible by exceptions
146 (Coro::State::throw) (testcase by sten).
147 - ->throw now puts threads into the ready queue, as this seems to
148 be expected by existing code, and code that doesn't cope with spurious
149 wakeups needs fixing anyway.
150 - use fd -1 in mmap.
151 - cast I32 to int in error message printf.
152 - warn about broken so-called "hardened" kernels.
153
1546.08 Fri Apr 13 12:05:47 CEST 2012
155 - be more aggressive about exiting like perl does - formerly,
156 exiting from the non-main thread would not execute END blocks.
157
1586.07 Fri Nov 11 21:21:48 CET 2011
159 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
160 - update ecb.h.
161
1626.06 Mon Aug 8 23:59:48 CEST 2011
163 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
164 backend, which is an order of magnitude slower. unfortunately, cygwins
165 pthread implementation isn't very complete either, so allocate the stack
166 twice just to be sure.
167 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
168 in its ithreaded perl - best recompile cygwin and use the 'w'indows
169 backend for much better performance. also disable ithreads for
170 even better performance...).
171
1726.05 Thu Aug 4 21:36:36 CEST 2011
173 - blush, condvar values would not be propagated from send to recv anymore
174 (reported by Chip Salzenberg).
175 - use exponential increase for the readline buffer length in
176 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
177
1786.04 Wed Aug 3 17:15:45 CEST 2011
179 - use even more efficient and more compatible condvars for
180 compatibility to AnyEvent 6.x :)
181 - more inconsequential ecb.h updates.
182
1836.03 Wed Aug 3 11:41:30 CEST 2011
184 - change how Coro patches AnyEvent condvars for compatibility to
185 AnyEvent 6.x.
186 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
187 hasn't been included.
188
1896.02 Wed Jul 13 04:35:19 CEST 2011
190 - "improve portability to Gentoo" - gentoo manages to put perl variables
191 in memory areas that are farther than 2gb apart, which the jit couldn't
192 handle and barfed. now it's just a bit slower on gentoo and similar
193 systems.
194
1956.01 Sun Jul 3 12:31:14 CEST 2011
196 - workarounds are good, but the test for whether pthreads are used
197 was not good. this one should be better.
198 - check differently whether gcc generates cfi instructions itself.
199
2006.0 Wed Jun 29 19:43:35 CEST 2011
201 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
202 destroyed and cleaned up automatically (e.g. async { schedule }).
203 - implement a JIT compiler for part of the thread switch code,
204 which gives a 50% speed improvement on threaded perls, and
205 about 4% on non-threaded perls (so threaded perls now finally
206 reach about half the speed of non-threaded perls).
207 - slightly modernise Coro::Intro, add section about rouse functions.
208 - avoid DEFSV and ERRSV, giving another 10% improvement
209 in thread switching.
210 - Coro::State->is_destroyed is now called is_zombie.
211 - implement a Coro->safe_cancel method that might fail, but
212 cancels in a "safer" way if it succeeds.
213 - add preliminary support for DEBUGGING perls.
214 - get rid of two hash-accesses when initialising a new Coro - this
215 speeds up coro creation by almost a factor of two.
216 - croak when a coro that is being cancelled tries to block
217 (e.g. while executing a guard block), instead of crashing or
218 deadlocking.
219 - use a more robust and also faster method to identify Coro::State
220 objects - speeds up everything a bit.
221 - implement Coro->cancel in XS for a 20% speed improvement, and to
222 be able to implement mutual cancellation.
223 - speed up context switches by a percent or two by more efficiently
224 allocating context stack entries.
225 - implement Coro->join and Coro->on_destroy in XS for a speedup and
226 a reduction in memory use.
227 - cancelling a coro while it itself is cancelling another coro is
228 now supported and working, instead of triggering an assertion.
229 - be a bit more crash-resistant when calling (buggy) on_destroy
230 callbacks (best effort).
231 - move on_destroy into the slf_frame, to allow extension slf
232 functions to have destructors.
233 - get rid if coro refcounting - simply crash in other interpreter
234 threads by nulling the pointers on clone.
235 - simplify warn/die hook handling when loading Coro - the convoluted
236 logic seems to be no longer neccessary.
237 - use libecb instead of our own home-grown gcc hacks.
238 - document alternatives to Coro::LWP. Please use them :)
239 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
240 sigaltstack. Really. wine suffers from it, erlang suffers from it,
241 and it's known since at least 2006.
242
2435.372 Wed Feb 23 06:14:30 CET 2011
244 - apparently mingw doesn't provide a working gettimeofday, try to
245 work around that by relying on Time::HiRes (indirectly brought to
246 my attention by Max Maischein).
247 - fix some portability issues when Time::HiRes was used.
248
2495.371 Mon Feb 21 14:36:08 CET 2011
250 - backport to windows process emulation code again.
251
2525.37 Sat Feb 19 07:49:44 CET 2011
253 - add a big "Coro thread life cycle" section to "man Coro".
254 - try a tentative workaround against the breakage that 5.13 has
255 introduced without depreciation period. sigh.
256 - no longer use Time::HiRes if gettimeofday is available, which
257 saves quite a lot of memory.
258
2595.36 Sun Feb 13 05:33:41 CET 2011
260 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
261 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
262 method call.
263 - undocument Coro::Timer::sleep and obsolete whole module.
264 - optimise Coro::Timer::timeout memory and cpu usage.
265 - slightly updated Coro::Intro for recent changes.
266 - do not initialise PL_dirty anymore.
267
2685.25 Thu Nov 11 01:08:39 CET 2010
269 - try a different approach on netbsd - netbsd 5 finally has marginally
270 working pthreads, but still broken ucontext/sigaltstack.
271 - openbsd 4.8 finally got their act together, Coro works out of the box
272 with asm, setjmp and pthreads (no change, just informational).
273
2745.24 Sat Oct 23 11:27:12 CEST 2010
275 - port to the EV 4.0 API.
276 - work around bugs in mingw32, making strawberry perl work
277 out of the box.
278 - correctly modify Coro::AIO function prototypes
279 so that they reflect the "no optional parameters" rule.
280 - "ported" libcoro to C++.
281
2825.23 Mon May 17 18:50:42 CEST 2010
283 - be more resistant to ordering changes when initialising
284 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
285 Waldorf).
286 - document that perl 5.12 deliberately removed support for cloning.
287
2885.22 Wed Apr 14 03:55:35 CEST 2010
289 - correctly return udnef on errors in Coro::Handle::read/write
290 (testcase by Marc Mims).
291 - convert Coro::Util into a "perl compatibility wrapper" - the functions
292 are less useful now, but are drop-in replacements for existing
293 functions, listing better alternatives in the documentation. This also
294 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
295 with Coro::Util::inet_aton.
296 - do not override $Coro::idle unconditionally in Coro.pm, as other
297 modules could have provided their own idle coro already
298 (for exmaple, Coro::AnyEvent).
299 - fix Coro::Util::gethost* functions.
300 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
301
3025.21 Wed Dec 16 07:19:51 CET 2009
303 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
304 together.
305 - add some examples on how to combine other event loops with Coro in
306 Coro::AnyEvent, and how to run it (and not to block). Seems to be
307 the most common source of confusion.
308 - try to catch people naively blocking in an event callback.
309 - work around the perl filehandle bug issue in conjunction with
310 older common::sense (as indirectly pointed out by ZSystem).
311 - clarify the "not from signal handlers" section.
312
3135.2 Sun Oct 4 14:54:24 CEST 2009
314 - Coro::Storable destroyed the prototypes of the functions it wrapped.
315 - export rouse_cb and rouse_wait by default now.
316 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
317 - new method $state->swap_sv.
318 - added section on "windows process emulation" to the manpage,
319 after a not-so-fruitful (nor-friendly) "discussion" with chip
320 salzenberg (discussion implies arguments, but his only arguments
321 were ad-hominems, one wonders why he started it in the first
322 place). I hope this explains it well enough for him to understand,
323 and maybe well enough for others to understand.
324 - use common::sense everywhere now.
325 - idle callbacks are no longer supported, use idle coros instead.
326 - print a thread listing when a deadlock is detected.
327
3285.17 Sat Aug 22 23:09:31 CEST 2009
329 - work around a bug in the perl debugger causing crashes
330 when running under the debugger by marking _pool_handler as nodebug.
331 - speed up Coro::async considerably.
332 - try some hacks to get netbsd to work "more often" - their broken
333 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
334 - convert Coro to AE 5.0 API.
335
3365.162 Tue Jul 28 04:04:03 CEST 2009
337 - perl 5.8.2 is now minimum requirement.
338 - skip t/19_handle.t on broken windows perls.
339
3405.161 Wed Jul 22 04:47:38 CEST 2009
341 - Coro::AnyEvent::poll could have a different prototype when EV was
342 used as backend (analyzed by Tatsuhiko Miyagawa).
343 - Coro::AnyEvent errornously initialised the event loop when loaded,
344 not on demand.
345 - try to workaround rare */t/01_unblock.t failures.
346
3475.16 Tue Jul 21 01:44:37 CEST 2009
348 - Coro::AnyEvent failed to hook into the event loop
349 when no threads had been readied between detecting
350 the event loop and actually running it.
351 - considerably speed up Coro::Select by taking avdantage
352 of AnyEvent > 4.8 and some other optimisations.
353 - implement paragraph readline mode in Coro::Handle
354 (based on patches by Zsbán Ambrus).
355 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
356 and analyzed by Yasuhiro MATSUMOTO).
357 - clarified libcoro license and copyright.
358 - someone stole my EXTRA_META!!!
359 - implement Coro::Select::patch_pp_sselect and it's brother,
360 for hardcode select overriding.
361
3625.151 Mon Jul 6 05:41:57 CEST 2009
363 - backport to windows process emulation code again (patch by
364 Yasuhiro MATSUMOTO).
365 - slightly update Coro::MakeMaker.
366
3675.15 Tue Jun 30 10:28:06 CEST 2009
368 - deprecate Coro::Socket, document how to get ipv6 support via
369 AnyEvent::Socket instead.
370 - implement signal->wait ($cb) interface, similar to semaphores.
371 - work around SvOK not supporting getmagic, so we have to getmagic
372 to test for undef :/ (reported by Matthias Waldorf).
373 - load Coro::AnyEvent in all modules using AnyEvent.
374 - work around perl corrupting our internal data structures,
375 reported by Tokuhiro Matsuno.
376 - enable per-coroutine real and cpu time gathering
377 (Coro::State::enable_times).
378
3795.14 Wed Jun 24 01:37:48 CEST 2009
380 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
381 as this seems to have been a difficult concept (poll, sleep, idle,
382 idle_upto).
383 - add Coro::AnyEvent::readable/writable functions.
384 - clarify Coro::EV/Event/AnyEvent manpages.
385 - free per-thread global scalars in the thread calling ->cancel, to
386 avoid crashes when $_, $@ etc., are magical but some of those
387 had already been freed.
388 - "unexperimentalise" the callback interface for Coro::Semaphore.
389 - speed up ready queue management/context switching by using a linked
390 list instead of an array (~5-10%).
391 - implement "watch" command in Coro::Debug shells.
392 - for fun, implement time-slicing as an example in the manpage.
393 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
394 Coro::Event, use the normal AnyEvent handling instead of dieing
395 (the same is true for Coro::Handle).
396 - properly document Coro::EV::timed_io_once.
397 - avoid unneccessary ->cancel calls in Coro::Handle.
398 - maybe make it work on mingw32 with win32 backend
399 (based on patch by Yasuhiro Matsumoto).
400
4015.132 Fri May 29 09:00:39 CEST 2009
402 - do not keep a reference to the argument itself in
403 Coro::Semaphore::guard, as it could change later.
404 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
405 should support a prepare callback.
406
4075.131 Mon Mar 16 23:20:37 CET 2009
408 - implement and document Coro->suspend, Coro->resume.
409 - fix Coro::Select implementation to not (often) close
410 the passed file descriptors (testcase provided by pippijn).
411
4125.13 Mon Dec 15 21:51:42 CET 2008
413 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
414 - don't set diehook to C<undef> but instead to NULL, to avoid
415 spurious warnings.
416 - fix a lot of bugs in Coro::SemaphoreSet.
417 - Coro::SemaphoreSet will less often create a semaphore needlessly.
418 - add Coro::SemaphoreSet::count and wait methods.
419 - take advantage of the new Guard module.
420 - deprecate Coro::guard.
421 - try to fix the dreaded 01_unblock tests once more. I hate it when
422 testsuites need more fixing than the code they are supposed to test.
423 - croak in more cases when a required callback isn't resolvable.
424 - fix some minor issues in Coro::State->call/eval.
425 - use current coroutine context instead of a temporary one
426 when temporarily switching to another coroutine.
427 - do not call C-level on_destroy handlers during global destruction,
428 to avoid needless segfaults.
429
4305.12 Sun Dec 7 13:30:38 CET 2008
431 - add default config for MirOS, which seems to be a bug-to-bug
432 compatible fork of openbsd ("world domination by releasing
433 openbsd cvs before the openbsd folks do it" or so :).
434 - free_padlist did destroy the names pad, not good, but didn't
435 seem to bother perl - this could fix issues such as eval ""
436 inside a function called from multiple coroutines.
437 - use a different method to detect destruction time.
438 - be more careful when freeing padlists just before global
439 destruction.
440 - fixed and expanded the call/cc example.
441 - renamed _terminate to _coro_run.
442 - new method Coro::Channel->shutdown.
443 - try pthreads on openbsd <4.4 (broken sigaltstack, will
444 pthreads fare better?).
445 - be less picky about destroying "a" running coroutine.

448 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
449 working code with failed assertions, introducing more bugs than
450 it fixes, requiring elaborate workarounds :(

4525.1 Mon Nov 24 08:54:59 CET 2008
453 - wrote a small introductory tutorial - Coro::Intro.
454 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
455 - Coro::Select did errornously dup the file descriptors
456 and didn't work with all AnyEvent backends.
457 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
458 LWP data transfers.
459 - disassociate c contexts from coro objects - this is agruably more
460 correct, but mostly allows sharing of cctxs between coro and state
461 objects, for added memory savings and speed increases.
462 - bumped $Coro::POOL_RSS up to 32kb by default.
463 - no longer set the optype to OP_CUSTOM, as B::* understandably
464 doesn't like this very much (and we *are* a type of entersub).
465 - implement state cloning, just to prove that call/cc can be done.
466 - automatically load Coro::AnyEvent in Coro::Handle.
467 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
468 do not have this method (and don't need it either).
469 - speed up generic anyevent methods in Coro::Handle by using rouse
470 callbacks.
471 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
472 others. It also makes the debugger happier, as you can trace
473 through the idle threads now.
474 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
475 - eg/event was pretty broken.
476 - better 5.8.6 compatibility.

482 - removed timed_* functions - they were not being used anyways
483 and should be replaced by a more generic mechanism -
484 and were annoying to support anyways :)
485 - removed SemaphoreSet's waiter method - use sem method instead.

22 would cause a deadlock (semaphore would get into a state where 491 would cause a deadlock (semaphore would get into a state where
23 it was available but waiters were waiting(. 492 it was available but waiters were still blocked).
24 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 493 - calling throw on a coroutine that is waiting for a semaphore will
494 no longer make it acquire the semaphore (and thus leak a count).
25 - perl's process emulation is now not even theoretically supported 495 - perl's process emulation is now not even theoretically supported
26 anymore. 496 anymore.
497 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
498 conversion of callback-style to blocking-style.
499 - new methods $coro->schedule_to and ->cede_to, to specifically
500 schedule or cede to a specific coroutine.
501 - new function Coro::Semaphore::wait.
502 - use named constants in Coro::Channel (Richard Hundt).

519 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
520 for a nice speedup and vastly more correct behaviour. Also implement
521 a new method "sem" to get at the underlying semaphore object.
522 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
523 (in comparison) 20-40% speedup.
524 - used new SLF interface to reimplement Coro::Signal gaining
525 some unknown (because I was too lazy), but certain, speedup, and also
526 making signals reliable for the first time.
527 - used new SLF interface and other optimisations to speed up async_pool
528 by a factor of two. It also doesn't rely on perl's exception mechanism
529 to exit anymore. The overhead for terminating an async_pool, coro over
530 a normal async is now very small.
531 - sped up coroutine creation/destruction by 40%.

536 - make "prefer perl native functions" work with threaded perls.
537 - condense Coro::Debug ps output, hint at v and w flags.
538 - (libcoro) lots of minor cleanups and portability improvements.
