185.13 136.56 Thu Feb 20 19:40:07 CET 2020
14 - Coro::EV::time*once functions used ev_once, which is not cancelable.
15 This could cause problems due to I/O watchers not being stopped up
16 on exceptions/cancellation.
17
186.55 Fri Jul 19 17:28:09 CEST 2019
19 - Coro::RWLock woke up only one reader instead of all after a wrlock
20 (analyzed and patch by Maxim Skorobogatov).
21 - slightly improved documentation of Coro::RWLock and RWLock testcase.
22 - quickly (re)-ported to minix 3.3 before minix crashed again.
23
246.54 Sun Dec 16 11:06:07 CET 2018
25 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
26
276.53 Sun Dec 16 10:33:15 CET 2018
28 - the autogenerated prototypes of Coro::AIO now add ";" at the end
29 to avoid generating named unary operators and messing up parsing
30 (mostly affects aio_mlockall 4 | 8 which was parsed as
31 (aio_mlockall 4) | 8).
32 - do not use a prototype for select in Coro::Select, as CORE::select also
33 doesn't have one.
34
356.52 Tue Aug 14 18:49:43 CEST 2018
36 - libcoro update: allow sharing of coro threads using the pthreads
37 backend among different pthreads, as is required by Coro::Multicore.
38 - always allow ->call and ->eval when the coro is the current coroutine. this
39 makes it possible, among other things, to call these on $Coro::main.
40 - minor code cleanups.
41
426.514 Thu Aug 31 18:25:31 CEST 2017
43 - safe_cancel no longer croaks when called on already-destroyed
44 thread, but instead "just works".
45
466.513 Sat Jul 15 01:18:51 CEST 2017
47 - experimental 5.22 comaptibility changes (PadlistNAMES).
48 - removed attributes example and made sure the other examples
49 still work.
50 - fix some statevar types for newer perls, should be of no consequence.
51
526.512 Fri Jul 14 05:03:17 CEST 2017
53 - seems to pass test suite down till 5.8.9, so make this the
54 minimum requirement in Makefile.PL.
55 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
56 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
57 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
58 fortified longjmp variants in some libcs.
59 - re-try JIT allocation without PROT_EXEC, to hopefully improve
60 portability (still doesn't seem to work around broken selinux
61 mmap everywhere).
62 - speling fixes (Xavier Guimard).
63
646.511 Sun Jun 26 23:44:50 CEST 2016
65 - make it compile with threaded perls again.
66 - simplify and speed up __DIE__ and __WARN__ handling.
67
686.51 Sat Jun 25 20:57:20 CEST 2016
69 - 6.5 release didn't compile on most older perls due to
70 a logic error enabling experimental 5.24 code for all versions.
71 - since various broken or deficient patches float around
72 to work around the vtbl API breakage in perl, let's provide
73 our own workaround, which seems to be much less invasive
74 and more compatible than the approaches seen so far. YMMV.
75 - work around assertion failure in perl_destruct on 5.24
76 (analyzed by Dave Mitchell).
77
786.5 Wed Jun 22 22:23:50 CEST 2016
79 - swap_sv swapping order was not symmetrical, causing
80 wrong swaps when swap_sv was used multiple times on the
81 same sv in the same thread.
82 - swap_sv calls can now be undone by calling it again
83 with the same variables.
84 - swap_sv calls will now be undone in async_pool threads.
85 - split Coro::Semaphore::up/adjust into separate xs functions
86 for better error reporting, at slight codesize increase.
87 - (libcoro) arm assembly support, please test and report.
88 - adjust to PL_savestack changes in perl 5.24 (adapted from
89 the debian patch, which unfortunately gets it wrong).
90
916.49 Sat Oct 17 01:40:12 CEST 2015
92 - throwing an exception to a thread waiting in
93 Coro::Handle using Coro::EV did not stop the watchers,
94 causing the next call to fail (testcase by Martin Pritchard).
95 - bump minimum perl version to 5.10.
96
976.48 Sun Oct 4 19:03:51 CEST 2015
98 - fix memory leak when Coro::Handle uses Coro::EV internally
99 (testcase by Sten Sten).
100 - update code to libev 4 API (internally, Coro still used the
101 version 3 API calls).
102 - remove unused hv_sig.
103
1046.47 Sat Jul 11 03:58:20 CEST 2015
105 - swap_svs - NVs can be in the SV head beginning with 5.20.
106
1076.46 Tue Jun 30 14:36:30 CEST 2015
108 - restore portability to perls with windows fork emulation
109 (patch by Petr Písař).
110
1116.45 Tue Jun 30 01:40:08 CEST 2015
112 - restore portability to perl 5.16 and below.
113
1146.44 Tue Jun 30 00:41:54 CEST 2015
115 - avoid segfaulting (or worse) when tracing a canceled thread.
116 - the Event module silently broke it's public hook API, causing
117 failures on perls compiled with -Duselongdouble. Requiring
118 the latest version of Event because I don't know which release
119 changed this (it's not mentioned in the ChangeLog).
120 - allow xs level enterleave hooks via CoroAPI.
121
1226.43 Thu Jun 4 15:38:14 CEST 2015
123 - use stability canary.
124 - port to stableperl-5.22.0-1.001.
125 - update libecb.
126
1276.42 Wed Feb 11 20:29:52 CET 2015
128 - Coro::SemaphoreSet->try did not actually work (analyzed by
129 SATO Kentaro).
130 - upgrade libecb to be C11 compliant.
131
1326.41 Sat Sep 6 22:08:46 CEST 2014
133 - restore portability to perl 5.8.x.
134 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
135 up some memory, but fixes "use feature" and similar modules
136 when used inside a Coro.
137 - allow zero as argument to Coro::Channel to mean the same thing
138 as no argument. this works with older versions as well,
139 but wasn't legal until now.
140 - slightly better c header file detection.
141
1426.39 Mon Jun 2 00:00:08 CEST 2014
143 - work around more incompatible changes in 5.20.
144
1456.38 Sun Jun 1 21:54:23 CEST 2014
146 - check that perl slots actually have enough space to hold
147 interpreter variables.
148 - untested port to perl 5.19 (64 bit tmps indices) (reported
149 by Andreas König).
150 - croak when cancel is called without a thread context.
151
1526.37 Tue Mar 4 13:27:33 CET 2014
153 - *sigh*, removed leftover debugging code from debugging a
154 perl bug, of all things.
155
1566.36 Tue Mar 4 07:11:59 CET 2014
157 - semaphores would not clear the destroy hook when interrupted
158 by ->throw, causing segfaults or worse.
159 - ->throw on a thread waiting for a semaphore did not acquire
160 the semaphore, but also didn't wake up other waiters,
161 possibly causing a deadlock.
162 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
163 to report a full stacktrace, which should help find out
164 where the actual call is.
165 - "atomically" destroy data in slf_destroy, because it is
166 the right thing to do, just in case.
167 - disable ecb.h libm dependency, to compile on ancient systems
168 or under adverse conditions.
169
1706.33 Mon Nov 18 11:26:27 CET 2013
171 - do not crash when freeing padlists with holes (in 5.18).
172 - tentative SVt_BIND 5.19 port/fix.
173
1746.32 Tue Nov 5 15:35:35 CET 2013
175 - use a new algorithm to derive padlists for perl 5.18. The old
176 one could lead to 0-pointer accesses inside perl (reported
177 by Darin McBride).
178
1796.31 Thu May 9 07:39:48 CEST 2013
180 - Coro::AIO requests would crash if the thread was ready'd
181 while the request was ongoing.
182
1836.29 Wed May 8 02:55:18 CEST 2013
184 - when an on_destroy handler destructs the coro currently being
185 destructed a perl scalar could be accessed after being freed,
186 likely causing a crash.
187
1886.28 Wed Mar 6 06:58:02 CET 2013
189 - clean remnants of existing __DIE__ and __WARN__ handlers so
190 they lose their magic and will not cause segfaults later
191 (testcase by Andrey Sagulin).
192 - improved Coro::State documentation a bit.
193 - Coro::Debug::command now flushes the output.
194 - add hack detection code for x32 abi, because the braindead slugs
195 who designed that made it look exactly like x86_64 without
196 providing proper compile time symbols to test for it. as a result,
197 this detection cannot work reliably.
198 - valgrind stack registering was broken.
199 - do not rely on Time::HiRes anymore in Coro::Debug.
200
2016.23 Fri Dec 7 23:36:37 CET 2012
202 - use experimental fiber implementation on native windows
203 perls.
204 - use sizeof (void *) as multiplication factor for stack sizes,
205 to accomodate the totally braindamaged microsoft 64 bit "os".
206 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
207 activeperl 5.16 crashes when PerlIO_define_layer is called due
208 to some bug in the perl dll, strawberry perl at least passes
209 the testsuite.
210 - implement Coro::Handle->peeraddr/host/port, for slightly
211 improved compatibility with LWP.
212 - implement 5.17 compatibility by almost blindly applying a
213 good-looking patch by Father Chrysostomos.
214 - move stack management functions into libcoro 3.
215 - libcoro version 3 "released".
216 - support magic values as timed_io_once args.
217 - recommend AnyEvent 7+ or EV 4+, also require EV
218 version 4 or newer for Coro::EV.
219
2206.10 Tue Oct 9 01:14:27 CEST 2012
221 - updated ecb.h, it had a typo that caused it to not compile on many
222 big endian systems (reported by many people).
223 - disable memory fences in ecb.h to improve portability.
224
2256.09 Sat Oct 6 23:25:02 CEST 2012
226 - Coro::EV I/O watchers were not interruptible by exceptions
227 (Coro::State::throw) (testcase by sten).
228 - ->throw now puts threads into the ready queue, as this seems to
229 be expected by existing code, and code that doesn't cope with spurious
230 wakeups needs fixing anyway.
231 - use fd -1 in mmap.
232 - cast I32 to int in error message printf.
233 - warn about broken so-called "hardened" kernels.
234
2356.08 Fri Apr 13 12:05:47 CEST 2012
236 - be more aggressive about exiting like perl does - formerly,
237 exiting from the non-main thread would not execute END blocks.
238
2396.07 Fri Nov 11 21:21:48 CET 2011
240 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
241 - update ecb.h.
242
2436.06 Mon Aug 8 23:59:48 CEST 2011
244 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
245 backend, which is an order of magnitude slower. unfortunately, cygwins
246 pthread implementation isn't very complete either, so allocate the stack
247 twice just to be sure.
248 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
249 in its ithreaded perl - best recompile cygwin and use the 'w'indows
250 backend for much better performance. also disable ithreads for
251 even better performance...).
252
2536.05 Thu Aug 4 21:36:36 CEST 2011
254 - blush, condvar values would not be propagated from send to recv anymore
255 (reported by Chip Salzenberg).
256 - use exponential increase for the readline buffer length in
257 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
258
2596.04 Wed Aug 3 17:15:45 CEST 2011
260 - use even more efficient and more compatible condvars for
261 compatibility to AnyEvent 6.x :)
262 - more inconsequential ecb.h updates.
263
2646.03 Wed Aug 3 11:41:30 CEST 2011
265 - change how Coro patches AnyEvent condvars for compatibility to
266 AnyEvent 6.x.
267 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
268 hasn't been included.
269
2706.02 Wed Jul 13 04:35:19 CEST 2011
271 - "improve portability to Gentoo" - gentoo manages to put perl variables
272 in memory areas that are farther than 2gb apart, which the jit couldn't
273 handle and barfed. now it's just a bit slower on gentoo and similar
274 systems.
275
2766.01 Sun Jul 3 12:31:14 CEST 2011
277 - workarounds are good, but the test for whether pthreads are used
278 was not good. this one should be better.
279 - check differently whether gcc generates cfi instructions itself.
280
2816.0 Wed Jun 29 19:43:35 CEST 2011
282 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
283 destroyed and cleaned up automatically (e.g. async { schedule }).
284 - implement a JIT compiler for part of the thread switch code,
285 which gives a 50% speed improvement on threaded perls, and
286 about 4% on non-threaded perls (so threaded perls now finally
287 reach about half the speed of non-threaded perls).
288 - slightly modernise Coro::Intro, add section about rouse functions.
289 - avoid DEFSV and ERRSV, giving another 10% improvement
290 in thread switching.
291 - Coro::State->is_destroyed is now called is_zombie.
292 - implement a Coro->safe_cancel method that might fail, but
293 cancels in a "safer" way if it succeeds.
294 - add preliminary support for DEBUGGING perls.
295 - get rid of two hash-accesses when initialising a new Coro - this
296 speeds up coro creation by almost a factor of two.
297 - croak when a coro that is being cancelled tries to block
298 (e.g. while executing a guard block), instead of crashing or
299 deadlocking.
300 - use a more robust and also faster method to identify Coro::State
301 objects - speeds up everything a bit.
302 - implement Coro->cancel in XS for a 20% speed improvement, and to
303 be able to implement mutual cancellation.
304 - speed up context switches by a percent or two by more efficiently
305 allocating context stack entries.
306 - implement Coro->join and Coro->on_destroy in XS for a speedup and
307 a reduction in memory use.
308 - cancelling a coro while it itself is cancelling another coro is
309 now supported and working, instead of triggering an assertion.
310 - be a bit more crash-resistant when calling (buggy) on_destroy
311 callbacks (best effort).
312 - move on_destroy into the slf_frame, to allow extension slf
313 functions to have destructors.
314 - get rid if coro refcounting - simply crash in other interpreter
315 threads by nulling the pointers on clone.
316 - simplify warn/die hook handling when loading Coro - the convoluted
317 logic seems to be no longer neccessary.
318 - use libecb instead of our own home-grown gcc hacks.
319 - document alternatives to Coro::LWP. Please use them :)
320 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
321 sigaltstack. Really. wine suffers from it, erlang suffers from it,
322 and it's known since at least 2006.
323
3245.372 Wed Feb 23 06:14:30 CET 2011
325 - apparently mingw doesn't provide a working gettimeofday, try to
326 work around that by relying on Time::HiRes (indirectly brought to
327 my attention by Max Maischein).
328 - fix some portability issues when Time::HiRes was used.
329
3305.371 Mon Feb 21 14:36:08 CET 2011
331 - backport to windows process emulation code again.
332
3335.37 Sat Feb 19 07:49:44 CET 2011
334 - add a big "Coro thread life cycle" section to "man Coro".
335 - try a tentative workaround against the breakage that 5.13 has
336 introduced without depreciation period. sigh.
337 - no longer use Time::HiRes if gettimeofday is available, which
338 saves quite a lot of memory.
339
3405.36 Sun Feb 13 05:33:41 CET 2011
341 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
342 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
343 method call.
344 - undocument Coro::Timer::sleep and obsolete whole module.
345 - optimise Coro::Timer::timeout memory and cpu usage.
346 - slightly updated Coro::Intro for recent changes.
347 - do not initialise PL_dirty anymore.
348
3495.25 Thu Nov 11 01:08:39 CET 2010
350 - try a different approach on netbsd - netbsd 5 finally has marginally
351 working pthreads, but still broken ucontext/sigaltstack.
352 - openbsd 4.8 finally got their act together, Coro works out of the box
353 with asm, setjmp and pthreads (no change, just informational).
354
3555.24 Sat Oct 23 11:27:12 CEST 2010
356 - port to the EV 4.0 API.
357 - work around bugs in mingw32, making strawberry perl work
358 out of the box.
359 - correctly modify Coro::AIO function prototypes
360 so that they reflect the "no optional parameters" rule.
361 - "ported" libcoro to C++.
362
3635.23 Mon May 17 18:50:42 CEST 2010
364 - be more resistant to ordering changes when initialising
365 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
366 Waldorf).
367 - document that perl 5.12 deliberately removed support for cloning.
368
3695.22 Wed Apr 14 03:55:35 CEST 2010
370 - correctly return udnef on errors in Coro::Handle::read/write
371 (testcase by Marc Mims).
372 - convert Coro::Util into a "perl compatibility wrapper" - the functions
373 are less useful now, but are drop-in replacements for existing
374 functions, listing better alternatives in the documentation. This also
375 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
376 with Coro::Util::inet_aton.
377 - do not override $Coro::idle unconditionally in Coro.pm, as other
378 modules could have provided their own idle coro already
379 (for exmaple, Coro::AnyEvent).
380 - fix Coro::Util::gethost* functions.
381 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
382
3835.21 Wed Dec 16 07:19:51 CET 2009
384 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
385 together.
386 - add some examples on how to combine other event loops with Coro in
387 Coro::AnyEvent, and how to run it (and not to block). Seems to be
388 the most common source of confusion.
389 - try to catch people naively blocking in an event callback.
390 - work around the perl filehandle bug issue in conjunction with
391 older common::sense (as indirectly pointed out by ZSystem).
392 - clarify the "not from signal handlers" section.
393
3945.2 Sun Oct 4 14:54:24 CEST 2009
395 - Coro::Storable destroyed the prototypes of the functions it wrapped.
396 - export rouse_cb and rouse_wait by default now.
397 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
398 - new method $state->swap_sv.
399 - added section on "windows process emulation" to the manpage,
400 after a not-so-fruitful (nor-friendly) "discussion" with chip
401 salzenberg (discussion implies arguments, but his only arguments
402 were ad-hominems, one wonders why he started it in the first
403 place). I hope this explains it well enough for him to understand,
404 and maybe well enough for others to understand.
405 - use common::sense everywhere now.
406 - idle callbacks are no longer supported, use idle coros instead.
407 - print a thread listing when a deadlock is detected.
408
4095.17 Sat Aug 22 23:09:31 CEST 2009
410 - work around a bug in the perl debugger causing crashes
411 when running under the debugger by marking _pool_handler as nodebug.
412 - speed up Coro::async considerably.
413 - try some hacks to get netbsd to work "more often" - their broken
414 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
415 - convert Coro to AE 5.0 API.
416
4175.162 Tue Jul 28 04:04:03 CEST 2009
418 - perl 5.8.2 is now minimum requirement.
419 - skip t/19_handle.t on broken windows perls.
420
4215.161 Wed Jul 22 04:47:38 CEST 2009
422 - Coro::AnyEvent::poll could have a different prototype when EV was
423 used as backend (analyzed by Tatsuhiko Miyagawa).
424 - Coro::AnyEvent errornously initialised the event loop when loaded,
425 not on demand.
426 - try to workaround rare */t/01_unblock.t failures.
427
4285.16 Tue Jul 21 01:44:37 CEST 2009
429 - Coro::AnyEvent failed to hook into the event loop
430 when no threads had been readied between detecting
431 the event loop and actually running it.
432 - considerably speed up Coro::Select by taking avdantage
433 of AnyEvent > 4.8 and some other optimisations.
434 - implement paragraph readline mode in Coro::Handle
435 (based on patches by Zsbán Ambrus).
436 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
437 and analyzed by Yasuhiro MATSUMOTO).
438 - clarified libcoro license and copyright.
439 - someone stole my EXTRA_META!!!
440 - implement Coro::Select::patch_pp_sselect and it's brother,
441 for hardcode select overriding.

4435.151 Mon Jul 6 05:41:57 CEST 2009
444 - backport to windows process emulation code again (patch by
445 Yasuhiro MATSUMOTO).
446 - slightly update Coro::MakeMaker.
447
4485.15 Tue Jun 30 10:28:06 CEST 2009
449 - deprecate Coro::Socket, document how to get ipv6 support via
450 AnyEvent::Socket instead.
451 - implement signal->wait ($cb) interface, similar to semaphores.
452 - work around SvOK not supporting getmagic, so we have to getmagic
453 to test for undef :/ (reported by Matthias Waldorf).
454 - load Coro::AnyEvent in all modules using AnyEvent.
455 - work around perl corrupting our internal data structures,
456 reported by Tokuhiro Matsuno.
457 - enable per-coroutine real and cpu time gathering
458 (Coro::State::enable_times).
459
4605.14 Wed Jun 24 01:37:48 CEST 2009
461 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
462 as this seems to have been a difficult concept (poll, sleep, idle,
463 idle_upto).
464 - add Coro::AnyEvent::readable/writable functions.
465 - clarify Coro::EV/Event/AnyEvent manpages.
466 - free per-thread global scalars in the thread calling ->cancel, to
467 avoid crashes when $_, $@ etc., are magical but some of those
468 had already been freed.
469 - "unexperimentalise" the callback interface for Coro::Semaphore.
470 - speed up ready queue management/context switching by using a linked
471 list instead of an array (~5-10%).
472 - implement "watch" command in Coro::Debug shells.
473 - for fun, implement time-slicing as an example in the manpage.
474 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
475 Coro::Event, use the normal AnyEvent handling instead of dieing
476 (the same is true for Coro::Handle).
477 - properly document Coro::EV::timed_io_once.
478 - avoid unneccessary ->cancel calls in Coro::Handle.
479 - maybe make it work on mingw32 with win32 backend
480 (based on patch by Yasuhiro Matsumoto).
481
4825.132 Fri May 29 09:00:39 CEST 2009
483 - do not keep a reference to the argument itself in
484 Coro::Semaphore::guard, as it could change later.
485 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
486 should support a prepare callback.
487
4885.131 Mon Mar 16 23:20:37 CET 2009
489 - implement and document Coro->suspend, Coro->resume.
490 - fix Coro::Select implementation to not (often) close
491 the passed file descriptors (testcase provided by pippijn).
492
4935.13 Mon Dec 15 21:51:42 CET 2008

502 - try to fix the dreaded 01_unblock tests once more. I hate it when
503 testsuites need more fixing than the code they are supposed to test.
504 - croak in more cases when a required callback isn't resolvable.
505 - fix some minor issues in Coro::State->call/eval.
506 - use current coroutine context instead of a temporary one
507 when temporarily switching to another coroutine.
508 - do not call C-level on_destroy handlers during global destruction,
509 to avoid needless segfaults.
