3TODO: should explore PerlIO::coroaio (perl leaks like hell). 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
8TODO: croak when async_pool tries to run canceled thread?

8TODO: async_pool to SLF 106.46 Tue Jun 30 14:36:30 CEST 2015
9TODO: _cancel to xs 11 - restore portability to perls with windows fork emulation
105.0 12 (reported by Petr Písař).
13
146.45 Tue Jun 30 01:40:08 CEST 2015
15 - restore portability to perl 5.16 and below.
16
176.44 Tue Jun 30 00:41:54 CEST 2015
18 - avoid segfaulting (or worse) when tracing a canceled thread.
19 - the Event module silently broke it's public hook API, causing
20 failures on perls compiled with -Duselongdouble. Requiring
21 the latest version of Event because I don't know which release
22 changed this (it's not mentioned in the ChangeLog).
23 - allow xs level enterleave hooks via CoroAPI.
24
256.43 Thu Jun 4 15:38:14 CEST 2015
26 - use stability canary.
27 - port to stableperl-5.22.0-1.001.
28 - update libecb.
29
306.42 Wed Feb 11 20:29:52 CET 2015
31 - Coro::SemaphoreSet->try did not actually work (analyzed by
32 SATO Kentaro).
33 - upgrade libecb to be C11 compliant.
34
356.41 Sat Sep 6 22:08:46 CEST 2014
36 - restore portability to perl 5.8.x.
37 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
38 up some memory, but fixes "use feature" and similar modules
39 when used inside a Coro.
40 - allow zero as argument to Coro::Channel to mean the same thing
41 as no argument. this works with older versions as well,
42 but wasn't legal until now.
43 - slightly better c header file detection.
44
456.39 Mon Jun 2 00:00:08 CEST 2014
46 - work around more incompatible changes in 5.20.
47
486.38 Sun Jun 1 21:54:23 CEST 2014
49 - check that perl slots actually have enough space to hold
50 interpreter variables.
51 - untested port to perl 5.19 (64 bit tmps indices) (reported
52 by Andreas König).
53 - croak when cancel is called without a thread context.
54
556.37 Tue Mar 4 13:27:33 CET 2014
56 - *sigh*, removed leftover debugging code from debugging a
57 perl bug, of all things.
58
596.36 Tue Mar 4 07:11:59 CET 2014
60 - semaphores would not clear the destroy hook when interrupted
61 by ->throw, causing segfaults or worse.
62 - ->throw on a thread waiting for a semaphore did not acquire
63 the semaphore, but also didn't wake up other waiters,
64 possibly causing a deadlock.
65 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
66 to report a full stacktrace, which should help find out
67 where the actual call is.
68 - "atomically" destroy data in slf_destroy, because it is
69 the right thing to do, just in case.
70 - disable ecb.h libm dependency, to compile on ancient systems
71 or under adverse conditions.
72
736.33 Mon Nov 18 11:26:27 CET 2013
74 - do not crash when freeing padlists with holes (in 5.18).
75 - tentative SVt_BIND 5.19 port/fix.
76
776.32 Tue Nov 5 15:35:35 CET 2013
78 - use a new algorithm to derive padlists for perl 5.18. The old
79 one could lead to 0-pointer accesses inside perl (reported
80 by Darin McBride).
81
826.31 Thu May 9 07:39:48 CEST 2013
83 - Coro::AIO requests would crash if the thread was ready'd
84 while the request was ongoing.
85
866.29 Wed May 8 02:55:18 CEST 2013
87 - when an on_destroy handler destructs the coro currently being
88 destructed a perl scalar could be accessed after being freed,
89 likely causing a crash.
90
916.28 Wed Mar 6 06:58:02 CET 2013
92 - clean remnants of existing __DIE__ and __WARN__ handlers so
93 they lose their magic and will not cause segfaults later
94 (testcase by Andrey Sagulin).
95 - improved Coro::State documentation a bit.
96 - Coro::Debug::command now flushes the output.
97 - add hack detection code for x32 abi, because the braindead slugs
98 who designed that made it look exactly like x86_64 without
99 providing proper compile time symbols to test for it. as a result,
100 this detection cannot work reliably.
101 - valgrind stack registering was broken.
102 - do not rely on Time::HiRes anymore in Coro::Debug.
103
1046.23 Fri Dec 7 23:36:37 CET 2012
105 - use experimental fiber implementation on native windows
106 perls.
107 - use sizeof (void *) as multiplication factor for stack sizes,
108 to accomodate the totally braindamaged microsoft 64 bit "os".
109 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
110 activeperl 5.16 crashes when PerlIO_define_layer is called due
111 to some bug in the perl dll, strawberry perl at least passes
112 the testsuite.
113 - implement Coro::Handle->peeraddr/host/port, for slightly
114 improved compatibility with LWP.
115 - implement 5.17 compatibility by almost blindly applying a
116 good-looking patch by Father Chrysostomos.
117 - move stack management functions into libcoro 3.
118 - libcoro version 3 "released".
119 - support magic values as timed_io_once args.
120 - recommend AnyEvent 7+ or EV 4+, also require EV
121 version 4 or newer for Coro::EV.
122
1236.10 Tue Oct 9 01:14:27 CEST 2012
124 - updated ecb.h, it had a typo that caused it to not compile on many
125 big endian systems (reported by many people).
126 - disable memory fences in ecb.h to improve portability.
127
1286.09 Sat Oct 6 23:25:02 CEST 2012
129 - Coro::EV I/O watchers were not interruptible by exceptions
130 (Coro::State::throw) (testcase by sten).
131 - ->throw now puts threads into the ready queue, as this seems to
132 be expected by existing code, and code that doesn't cope with spurious
133 wakeups needs fixing anyway.
134 - use fd -1 in mmap.
135 - cast I32 to int in error message printf.
136 - warn about broken so-called "hardened" kernels.
137
1386.08 Fri Apr 13 12:05:47 CEST 2012
139 - be more aggressive about exiting like perl does - formerly,
140 exiting from the non-main thread would not execute END blocks.
141
1426.07 Fri Nov 11 21:21:48 CET 2011
143 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
144 - update ecb.h.
145
1466.06 Mon Aug 8 23:59:48 CEST 2011
147 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
148 backend, which is an order of magnitude slower. unfortunately, cygwins
149 pthread implementation isn't very complete either, so allocate the stack
150 twice just to be sure.
151 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
152 in its ithreaded perl - best recompile cygwin and use the 'w'indows
153 backend for much better performance. also disable ithreads for
154 even better performance...).
155
1566.05 Thu Aug 4 21:36:36 CEST 2011
157 - blush, condvar values would not be propagated from send to recv anymore
158 (reported by Chip Salzenberg).
159 - use exponential increase for the readline buffer length in
160 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
161
1626.04 Wed Aug 3 17:15:45 CEST 2011
163 - use even more efficient and more compatible condvars for
164 compatibility to AnyEvent 6.x :)
165 - more inconsequential ecb.h updates.
166
1676.03 Wed Aug 3 11:41:30 CEST 2011
168 - change how Coro patches AnyEvent condvars for compatibility to
169 AnyEvent 6.x.
170 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
171 hasn't been included.
172
1736.02 Wed Jul 13 04:35:19 CEST 2011
174 - "improve portability to Gentoo" - gentoo manages to put perl variables
175 in memory areas that are farther than 2gb apart, which the jit couldn't
176 handle and barfed. now it's just a bit slower on gentoo and similar
177 systems.
178
1796.01 Sun Jul 3 12:31:14 CEST 2011
180 - workarounds are good, but the test for whether pthreads are used
181 was not good. this one should be better.
182 - check differently whether gcc generates cfi instructions itself.
183
1846.0 Wed Jun 29 19:43:35 CEST 2011
185 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
186 destroyed and cleaned up automatically (e.g. async { schedule }).
187 - implement a JIT compiler for part of the thread switch code,
188 which gives a 50% speed improvement on threaded perls, and
189 about 4% on non-threaded perls (so threaded perls now finally
190 reach about half the speed of non-threaded perls).
191 - slightly modernise Coro::Intro, add section about rouse functions.
192 - avoid DEFSV and ERRSV, giving another 10% improvement
193 in thread switching.
194 - Coro::State->is_destroyed is now called is_zombie.
195 - implement a Coro->safe_cancel method that might fail, but
196 cancels in a "safer" way if it succeeds.
197 - add preliminary support for DEBUGGING perls.
198 - get rid of two hash-accesses when initialising a new Coro - this
199 speeds up coro creation by almost a factor of two.
200 - croak when a coro that is being cancelled tries to block
201 (e.g. while executing a guard block), instead of crashing or
202 deadlocking.
203 - use a more robust and also faster method to identify Coro::State
204 objects - speeds up everything a bit.
205 - implement Coro->cancel in XS for a 20% speed improvement, and to
206 be able to implement mutual cancellation.
207 - speed up context switches by a percent or two by more efficiently
208 allocating context stack entries.
209 - implement Coro->join and Coro->on_destroy in XS for a speedup and
210 a reduction in memory use.
211 - cancelling a coro while it itself is cancelling another coro is
212 now supported and working, instead of triggering an assertion.
213 - be a bit more crash-resistant when calling (buggy) on_destroy
214 callbacks (best effort).
215 - move on_destroy into the slf_frame, to allow extension slf
216 functions to have destructors.
217 - get rid if coro refcounting - simply crash in other interpreter
218 threads by nulling the pointers on clone.
219 - simplify warn/die hook handling when loading Coro - the convoluted
220 logic seems to be no longer neccessary.
221 - use libecb instead of our own home-grown gcc hacks.
222 - document alternatives to Coro::LWP. Please use them :)
223 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
224 sigaltstack. Really. wine suffers from it, erlang suffers from it,
225 and it's known since at least 2006.
226
2275.372 Wed Feb 23 06:14:30 CET 2011
228 - apparently mingw doesn't provide a working gettimeofday, try to
229 work around that by relying on Time::HiRes (indirectly brought to
230 my attention by Max Maischein).
231 - fix some portability issues when Time::HiRes was used.
232
2335.371 Mon Feb 21 14:36:08 CET 2011
234 - backport to windows process emulation code again.
235
2365.37 Sat Feb 19 07:49:44 CET 2011
237 - add a big "Coro thread life cycle" section to "man Coro".
238 - try a tentative workaround against the breakage that 5.13 has
239 introduced without depreciation period. sigh.
240 - no longer use Time::HiRes if gettimeofday is available, which
241 saves quite a lot of memory.
242
2435.36 Sun Feb 13 05:33:41 CET 2011
244 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
245 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
246 method call.
247 - undocument Coro::Timer::sleep and obsolete whole module.
248 - optimise Coro::Timer::timeout memory and cpu usage.
249 - slightly updated Coro::Intro for recent changes.
250 - do not initialise PL_dirty anymore.
251
2525.25 Thu Nov 11 01:08:39 CET 2010
253 - try a different approach on netbsd - netbsd 5 finally has marginally
254 working pthreads, but still broken ucontext/sigaltstack.
255 - openbsd 4.8 finally got their act together, Coro works out of the box
256 with asm, setjmp and pthreads (no change, just informational).
257
2585.24 Sat Oct 23 11:27:12 CEST 2010
259 - port to the EV 4.0 API.
260 - work around bugs in mingw32, making strawberry perl work
261 out of the box.
262 - correctly modify Coro::AIO function prototypes
263 so that they reflect the "no optional parameters" rule.
264 - "ported" libcoro to C++.
265
2665.23 Mon May 17 18:50:42 CEST 2010
267 - be more resistant to ordering changes when initialising
268 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
269 Waldorf).
270 - document that perl 5.12 deliberately removed support for cloning.
271
2725.22 Wed Apr 14 03:55:35 CEST 2010
273 - correctly return udnef on errors in Coro::Handle::read/write
274 (testcase by Marc Mims).
275 - convert Coro::Util into a "perl compatibility wrapper" - the functions
276 are less useful now, but are drop-in replacements for existing
277 functions, listing better alternatives in the documentation. This also
278 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
279 with Coro::Util::inet_aton.
280 - do not override $Coro::idle unconditionally in Coro.pm, as other
281 modules could have provided their own idle coro already
282 (for exmaple, Coro::AnyEvent).
283 - fix Coro::Util::gethost* functions.
284 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
285
2865.21 Wed Dec 16 07:19:51 CET 2009
287 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
288 together.
289 - add some examples on how to combine other event loops with Coro in
290 Coro::AnyEvent, and how to run it (and not to block). Seems to be
291 the most common source of confusion.
292 - try to catch people naively blocking in an event callback.
293 - work around the perl filehandle bug issue in conjunction with
294 older common::sense (as indirectly pointed out by ZSystem).
295 - clarify the "not from signal handlers" section.
296
2975.2 Sun Oct 4 14:54:24 CEST 2009
298 - Coro::Storable destroyed the prototypes of the functions it wrapped.
299 - export rouse_cb and rouse_wait by default now.
300 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
301 - new method $state->swap_sv.
302 - added section on "windows process emulation" to the manpage,
303 after a not-so-fruitful (nor-friendly) "discussion" with chip
304 salzenberg (discussion implies arguments, but his only arguments
305 were ad-hominems, one wonders why he started it in the first
306 place). I hope this explains it well enough for him to understand,
307 and maybe well enough for others to understand.
308 - use common::sense everywhere now.
309 - idle callbacks are no longer supported, use idle coros instead.
310 - print a thread listing when a deadlock is detected.
311
3125.17 Sat Aug 22 23:09:31 CEST 2009
313 - work around a bug in the perl debugger causing crashes
314 when running under the debugger by marking _pool_handler as nodebug.
315 - speed up Coro::async considerably.
316 - try some hacks to get netbsd to work "more often" - their broken
317 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
318 - convert Coro to AE 5.0 API.
319
3205.162 Tue Jul 28 04:04:03 CEST 2009
321 - perl 5.8.2 is now minimum requirement.
322 - skip t/19_handle.t on broken windows perls.
323
3245.161 Wed Jul 22 04:47:38 CEST 2009
325 - Coro::AnyEvent::poll could have a different prototype when EV was
326 used as backend (analyzed by Tatsuhiko Miyagawa).
327 - Coro::AnyEvent errornously initialised the event loop when loaded,
328 not on demand.
329 - try to workaround rare */t/01_unblock.t failures.
330
3315.16 Tue Jul 21 01:44:37 CEST 2009
332 - Coro::AnyEvent failed to hook into the event loop
333 when no threads had been readied between detecting
334 the event loop and actually running it.
335 - considerably speed up Coro::Select by taking avdantage
336 of AnyEvent > 4.8 and some other optimisations.
337 - implement paragraph readline mode in Coro::Handle
338 (based on patches by Zsbán Ambrus).
339 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
340 and analyzed by Yasuhiro MATSUMOTO).
341 - clarified libcoro license and copyright.
342 - someone stole my EXTRA_META!!!
343 - implement Coro::Select::patch_pp_sselect and it's brother,
344 for hardcode select overriding.
345
3465.151 Mon Jul 6 05:41:57 CEST 2009
347 - backport to windows process emulation code again (patch by
348 Yasuhiro MATSUMOTO).
349 - slightly update Coro::MakeMaker.
350
3515.15 Tue Jun 30 10:28:06 CEST 2009
352 - deprecate Coro::Socket, document how to get ipv6 support via
353 AnyEvent::Socket instead.
354 - implement signal->wait ($cb) interface, similar to semaphores.
355 - work around SvOK not supporting getmagic, so we have to getmagic
356 to test for undef :/ (reported by Matthias Waldorf).
357 - load Coro::AnyEvent in all modules using AnyEvent.
358 - work around perl corrupting our internal data structures,
359 reported by Tokuhiro Matsuno.
360 - enable per-coroutine real and cpu time gathering
361 (Coro::State::enable_times).
362
3635.14 Wed Jun 24 01:37:48 CEST 2009
364 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
365 as this seems to have been a difficult concept (poll, sleep, idle,
366 idle_upto).
367 - add Coro::AnyEvent::readable/writable functions.
368 - clarify Coro::EV/Event/AnyEvent manpages.
369 - free per-thread global scalars in the thread calling ->cancel, to
370 avoid crashes when $_, $@ etc., are magical but some of those
371 had already been freed.
372 - "unexperimentalise" the callback interface for Coro::Semaphore.
373 - speed up ready queue management/context switching by using a linked
374 list instead of an array (~5-10%).
375 - implement "watch" command in Coro::Debug shells.
376 - for fun, implement time-slicing as an example in the manpage.
377 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
378 Coro::Event, use the normal AnyEvent handling instead of dieing
379 (the same is true for Coro::Handle).
380 - properly document Coro::EV::timed_io_once.
381 - avoid unneccessary ->cancel calls in Coro::Handle.
382 - maybe make it work on mingw32 with win32 backend
383 (based on patch by Yasuhiro Matsumoto).
384
3855.132 Fri May 29 09:00:39 CEST 2009
386 - do not keep a reference to the argument itself in
387 Coro::Semaphore::guard, as it could change later.
388 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
389 should support a prepare callback.
390
3915.131 Mon Mar 16 23:20:37 CET 2009
392 - implement and document Coro->suspend, Coro->resume.
393 - fix Coro::Select implementation to not (often) close
394 the passed file descriptors (testcase provided by pippijn).
395
3965.13 Mon Dec 15 21:51:42 CET 2008
397 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
398 - don't set diehook to C<undef> but instead to NULL, to avoid
399 spurious warnings.
400 - fix a lot of bugs in Coro::SemaphoreSet.
401 - Coro::SemaphoreSet will less often create a semaphore needlessly.
402 - add Coro::SemaphoreSet::count and wait methods.
403 - take advantage of the new Guard module.
404 - deprecate Coro::guard.
405 - try to fix the dreaded 01_unblock tests once more. I hate it when
406 testsuites need more fixing than the code they are supposed to test.
407 - croak in more cases when a required callback isn't resolvable.
408 - fix some minor issues in Coro::State->call/eval.
409 - use current coroutine context instead of a temporary one
410 when temporarily switching to another coroutine.
411 - do not call C-level on_destroy handlers during global destruction,
412 to avoid needless segfaults.
413
4145.12 Sun Dec 7 13:30:38 CET 2008
415 - add default config for MirOS, which seems to be a bug-to-bug
416 compatible fork of openbsd ("world domination by releasing
417 openbsd cvs before the openbsd folks do it" or so :).
418 - free_padlist did destroy the names pad, not good, but didn't
419 seem to bother perl - this could fix issues such as eval ""
420 inside a function called from multiple coroutines.
421 - use a different method to detect destruction time.
422 - be more careful when freeing padlists just before global
423 destruction.
424 - fixed and expanded the call/cc example.
425 - renamed _terminate to _coro_run.
426 - new method Coro::Channel->shutdown.
427 - try pthreads on openbsd <4.4 (broken sigaltstack, will
428 pthreads fare better?).
429 - be less picky about destroying "a" running coroutine.
430
4315.11 Tue Nov 25 21:49:05 CET 2008
432 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
433 working code with failed assertions, introducing more bugs than
434 it fixes, requiring elaborate workarounds :(
435
4365.1 Mon Nov 24 08:54:59 CET 2008
437 - wrote a small introductory tutorial - Coro::Intro.
438 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
439 - Coro::Select did errornously dup the file descriptors
440 and didn't work with all AnyEvent backends.
441 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
442 LWP data transfers.
443 - disassociate c contexts from coro objects - this is agruably more
444 correct, but mostly allows sharing of cctxs between coro and state
445 objects, for added memory savings and speed increases.
446 - bumped $Coro::POOL_RSS up to 32kb by default.
447 - no longer set the optype to OP_CUSTOM, as B::* understandably
448 doesn't like this very much (and we *are* a type of entersub).
449 - implement state cloning, just to prove that call/cc can be done.
450 - automatically load Coro::AnyEvent in Coro::Handle.
451 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
452 do not have this method (and don't need it either).
453 - speed up generic anyevent methods in Coro::Handle by using rouse
454 callbacks.
455 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
456 others. It also makes the debugger happier, as you can trace
457 through the idle threads now.
458 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
459 - eg/event was pretty broken.
460 - better 5.8.6 compatibility.
