96.513 Sat Jul 15 01:18:51 CEST 2017
10 - experimental 5.22 comaptibility changes (PadlistNAMES).
11 - removed attributes example and made sure the other examples
12 still work.
13 - fix some statevar types for newer perls, should be of no consequence.
14
156.512 Fri Jul 14 05:03:17 CEST 2017
16 - seems to pass test suite down till 5.8.9, so make this the
17 minimum requirement in Makefile.PL.
18 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
19 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
20 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
21 fortified longjmp variants in some libcs.
22 - re-try JIT allocation without PROT_EXEC, to hopefully improve
23 portability (still doesn't seem to work around broken selinux
24 mmap everywhere).
25 - speling fixes (Xavier Guimard).
26
276.511 Sun Jun 26 23:44:50 CEST 2016
28 - make it compile with threaded perls again.
29 - simplify and speed up __DIE__ and __WARN__ handling.
30
316.51 Sat Jun 25 20:57:20 CEST 2016
32 - 6.5 release didn't compile on most older perls due to
33 a logic error enabling experimental 5.24 code for all versions.
34 - since various broken or deficient patches float around
35 to work around the vtbl API breakage in perl, let's provide
36 our own workaround, which seems to be much less invasive
37 and more compatible than the approaches seen so far. YMMV.
38 - work around assertion failure in perl_destruct on 5.24
39 (analyzed by Dave Mitchell).
40
416.5 Wed Jun 22 22:23:50 CEST 2016
42 - swap_sv swapping order was not symmetrical, causing
43 wrong swaps when swap_sv was used multiple times on the
44 same sv in the same thread.
45 - swap_sv calls can now be undone by calling it again
46 with the same variables.
47 - swap_sv calls will now be undone in async_pool threads.
48 - split Coro::Semaphore::up/adjust into separate xs functions
49 for better error reporting, at slight codesize increase.
50 - (libcoro) arm assembly support, please test and report.
51 - adjust to PL_savestack changes in perl 5.24 (adapted from
52 the debian patch, which unfortunately gets it wrong).
53
546.49 Sat Oct 17 01:40:12 CEST 2015
55 - throwing an exception to a thread waiting in
56 Coro::Handle using Coro::EV did not stop the watchers,
57 causing the next call to fail (testcase by Martin Pritchard).
58 - bump minimum perl version to 5.10.
59
606.48 Sun Oct 4 19:03:51 CEST 2015
61 - fix memory leak when Coro::Handle uses Coro::EV internally
62 (testcase by Sten Sten).
63 - update code to libev 4 API (internally, Coro still used the
64 version 3 API calls).
65 - remove unused hv_sig.
66
676.47 Sat Jul 11 03:58:20 CEST 2015
68 - swap_svs - NVs can be in the SV head beginning with 5.20.
69
706.46 Tue Jun 30 14:36:30 CEST 2015
71 - restore portability to perls with windows fork emulation
72 (patch by Petr Písař).
73
746.45 Tue Jun 30 01:40:08 CEST 2015
75 - restore portability to perl 5.16 and below.
76
776.44 Tue Jun 30 00:41:54 CEST 2015
78 - avoid segfaulting (or worse) when tracing a canceled thread.
79 - the Event module silently broke it's public hook API, causing
80 failures on perls compiled with -Duselongdouble. Requiring
81 the latest version of Event because I don't know which release
82 changed this (it's not mentioned in the ChangeLog).
83 - allow xs level enterleave hooks via CoroAPI.
84
856.43 Thu Jun 4 15:38:14 CEST 2015
86 - use stability canary.
87 - port to stableperl-5.22.0-1.001.
88 - update libecb.
89
906.42 Wed Feb 11 20:29:52 CET 2015
91 - Coro::SemaphoreSet->try did not actually work (analyzed by
92 SATO Kentaro).
93 - upgrade libecb to be C11 compliant.
94
956.41 Sat Sep 6 22:08:46 CEST 2014
96 - restore portability to perl 5.8.x.
97 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
98 up some memory, but fixes "use feature" and similar modules
99 when used inside a Coro.
100 - allow zero as argument to Coro::Channel to mean the same thing
101 as no argument. this works with older versions as well,
102 but wasn't legal until now.
103 - slightly better c header file detection.
104
1056.39 Mon Jun 2 00:00:08 CEST 2014
106 - work around more incompatible changes in 5.20.
107
1086.38 Sun Jun 1 21:54:23 CEST 2014
109 - check that perl slots actually have enough space to hold
110 interpreter variables.
111 - untested port to perl 5.19 (64 bit tmps indices) (reported
112 by Andreas König).
113 - croak when cancel is called without a thread context.
114
1156.37 Tue Mar 4 13:27:33 CET 2014
116 - *sigh*, removed leftover debugging code from debugging a
117 perl bug, of all things.
118
1196.36 Tue Mar 4 07:11:59 CET 2014
120 - semaphores would not clear the destroy hook when interrupted
121 by ->throw, causing segfaults or worse.
122 - ->throw on a thread waiting for a semaphore did not acquire
123 the semaphore, but also didn't wake up other waiters,
124 possibly causing a deadlock.
125 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
126 to report a full stacktrace, which should help find out
127 where the actual call is.
128 - "atomically" destroy data in slf_destroy, because it is
129 the right thing to do, just in case.
130 - disable ecb.h libm dependency, to compile on ancient systems
131 or under adverse conditions.
132
1336.33 Mon Nov 18 11:26:27 CET 2013
134 - do not crash when freeing padlists with holes (in 5.18).
135 - tentative SVt_BIND 5.19 port/fix.
136
1376.32 Tue Nov 5 15:35:35 CET 2013
138 - use a new algorithm to derive padlists for perl 5.18. The old
139 one could lead to 0-pointer accesses inside perl (reported
140 by Darin McBride).
141
1426.31 Thu May 9 07:39:48 CEST 2013
143 - Coro::AIO requests would crash if the thread was ready'd
144 while the request was ongoing.
145
1466.29 Wed May 8 02:55:18 CEST 2013
147 - when an on_destroy handler destructs the coro currently being
148 destructed a perl scalar could be accessed after being freed,
149 likely causing a crash.
150
1516.28 Wed Mar 6 06:58:02 CET 2013
152 - clean remnants of existing __DIE__ and __WARN__ handlers so
153 they lose their magic and will not cause segfaults later
154 (testcase by Andrey Sagulin).
155 - improved Coro::State documentation a bit.
156 - Coro::Debug::command now flushes the output.
157 - add hack detection code for x32 abi, because the braindead slugs
158 who designed that made it look exactly like x86_64 without
159 providing proper compile time symbols to test for it. as a result,
160 this detection cannot work reliably.
161 - valgrind stack registering was broken.
162 - do not rely on Time::HiRes anymore in Coro::Debug.
163
1646.23 Fri Dec 7 23:36:37 CET 2012
165 - use experimental fiber implementation on native windows
166 perls.
167 - use sizeof (void *) as multiplication factor for stack sizes,
168 to accomodate the totally braindamaged microsoft 64 bit "os".
169 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
170 activeperl 5.16 crashes when PerlIO_define_layer is called due
171 to some bug in the perl dll, strawberry perl at least passes
172 the testsuite.
173 - implement Coro::Handle->peeraddr/host/port, for slightly
174 improved compatibility with LWP.
175 - implement 5.17 compatibility by almost blindly applying a
176 good-looking patch by Father Chrysostomos.
177 - move stack management functions into libcoro 3.
178 - libcoro version 3 "released".
179 - support magic values as timed_io_once args.
180 - recommend AnyEvent 7+ or EV 4+, also require EV
181 version 4 or newer for Coro::EV.
182
1836.10 Tue Oct 9 01:14:27 CEST 2012
184 - updated ecb.h, it had a typo that caused it to not compile on many
185 big endian systems (reported by many people).
186 - disable memory fences in ecb.h to improve portability.
187
1886.09 Sat Oct 6 23:25:02 CEST 2012
189 - Coro::EV I/O watchers were not interruptible by exceptions
190 (Coro::State::throw) (testcase by sten).
191 - ->throw now puts threads into the ready queue, as this seems to
192 be expected by existing code, and code that doesn't cope with spurious
193 wakeups needs fixing anyway.
194 - use fd -1 in mmap.
195 - cast I32 to int in error message printf.
196 - warn about broken so-called "hardened" kernels.
197
1986.08 Fri Apr 13 12:05:47 CEST 2012
199 - be more aggressive about exiting like perl does - formerly,
200 exiting from the non-main thread would not execute END blocks.
201
2026.07 Fri Nov 11 21:21:48 CET 2011
203 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
204 - update ecb.h.
205
2066.06 Mon Aug 8 23:59:48 CEST 2011
207 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
208 backend, which is an order of magnitude slower. unfortunately, cygwins
209 pthread implementation isn't very complete either, so allocate the stack
210 twice just to be sure.
211 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
212 in its ithreaded perl - best recompile cygwin and use the 'w'indows
213 backend for much better performance. also disable ithreads for
214 even better performance...).
215
2166.05 Thu Aug 4 21:36:36 CEST 2011
217 - blush, condvar values would not be propagated from send to recv anymore
218 (reported by Chip Salzenberg).
219 - use exponential increase for the readline buffer length in
220 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
221
2226.04 Wed Aug 3 17:15:45 CEST 2011
223 - use even more efficient and more compatible condvars for
224 compatibility to AnyEvent 6.x :)
225 - more inconsequential ecb.h updates.
226
2276.03 Wed Aug 3 11:41:30 CEST 2011
228 - change how Coro patches AnyEvent condvars for compatibility to
229 AnyEvent 6.x.
230 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
231 hasn't been included.
232
2336.02 Wed Jul 13 04:35:19 CEST 2011
234 - "improve portability to Gentoo" - gentoo manages to put perl variables
235 in memory areas that are farther than 2gb apart, which the jit couldn't
236 handle and barfed. now it's just a bit slower on gentoo and similar
237 systems.
238
2396.01 Sun Jul 3 12:31:14 CEST 2011
240 - workarounds are good, but the test for whether pthreads are used
241 was not good. this one should be better.
242 - check differently whether gcc generates cfi instructions itself.
243
2446.0 Wed Jun 29 19:43:35 CEST 2011
245 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
246 destroyed and cleaned up automatically (e.g. async { schedule }).
247 - implement a JIT compiler for part of the thread switch code,
248 which gives a 50% speed improvement on threaded perls, and
249 about 4% on non-threaded perls (so threaded perls now finally
250 reach about half the speed of non-threaded perls).
251 - slightly modernise Coro::Intro, add section about rouse functions.
252 - avoid DEFSV and ERRSV, giving another 10% improvement
253 in thread switching.
254 - Coro::State->is_destroyed is now called is_zombie.
255 - implement a Coro->safe_cancel method that might fail, but
256 cancels in a "safer" way if it succeeds.
257 - add preliminary support for DEBUGGING perls.
258 - get rid of two hash-accesses when initialising a new Coro - this
259 speeds up coro creation by almost a factor of two.
260 - croak when a coro that is being cancelled tries to block
261 (e.g. while executing a guard block), instead of crashing or
262 deadlocking.
263 - use a more robust and also faster method to identify Coro::State
264 objects - speeds up everything a bit.
265 - implement Coro->cancel in XS for a 20% speed improvement, and to
266 be able to implement mutual cancellation.
267 - speed up context switches by a percent or two by more efficiently
268 allocating context stack entries.
269 - implement Coro->join and Coro->on_destroy in XS for a speedup and
270 a reduction in memory use.
271 - cancelling a coro while it itself is cancelling another coro is
272 now supported and working, instead of triggering an assertion.
273 - be a bit more crash-resistant when calling (buggy) on_destroy
274 callbacks (best effort).
275 - move on_destroy into the slf_frame, to allow extension slf
276 functions to have destructors.
277 - get rid if coro refcounting - simply crash in other interpreter
278 threads by nulling the pointers on clone.
279 - simplify warn/die hook handling when loading Coro - the convoluted
280 logic seems to be no longer neccessary.
281 - use libecb instead of our own home-grown gcc hacks.
282 - document alternatives to Coro::LWP. Please use them :)
283 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
284 sigaltstack. Really. wine suffers from it, erlang suffers from it,
285 and it's known since at least 2006.
286
2875.372 Wed Feb 23 06:14:30 CET 2011
288 - apparently mingw doesn't provide a working gettimeofday, try to
289 work around that by relying on Time::HiRes (indirectly brought to
290 my attention by Max Maischein).
291 - fix some portability issues when Time::HiRes was used.
292
2935.371 Mon Feb 21 14:36:08 CET 2011
294 - backport to windows process emulation code again.
295
2965.37 Sat Feb 19 07:49:44 CET 2011
297 - add a big "Coro thread life cycle" section to "man Coro".
298 - try a tentative workaround against the breakage that 5.13 has
299 introduced without depreciation period. sigh.
300 - no longer use Time::HiRes if gettimeofday is available, which
301 saves quite a lot of memory.
302
3035.36 Sun Feb 13 05:33:41 CET 2011
304 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
305 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
306 method call.
307 - undocument Coro::Timer::sleep and obsolete whole module.
308 - optimise Coro::Timer::timeout memory and cpu usage.
309 - slightly updated Coro::Intro for recent changes.
310 - do not initialise PL_dirty anymore.
311
3125.25 Thu Nov 11 01:08:39 CET 2010
313 - try a different approach on netbsd - netbsd 5 finally has marginally
314 working pthreads, but still broken ucontext/sigaltstack.
315 - openbsd 4.8 finally got their act together, Coro works out of the box
316 with asm, setjmp and pthreads (no change, just informational).
317
3185.24 Sat Oct 23 11:27:12 CEST 2010
319 - port to the EV 4.0 API.
320 - work around bugs in mingw32, making strawberry perl work
321 out of the box.
322 - correctly modify Coro::AIO function prototypes
323 so that they reflect the "no optional parameters" rule.
324 - "ported" libcoro to C++.
325
3265.23 Mon May 17 18:50:42 CEST 2010
327 - be more resistant to ordering changes when initialising
328 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
329 Waldorf).
330 - document that perl 5.12 deliberately removed support for cloning.
331
3325.22 Wed Apr 14 03:55:35 CEST 2010
333 - correctly return udnef on errors in Coro::Handle::read/write
334 (testcase by Marc Mims).
335 - convert Coro::Util into a "perl compatibility wrapper" - the functions
336 are less useful now, but are drop-in replacements for existing
337 functions, listing better alternatives in the documentation. This also
338 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
339 with Coro::Util::inet_aton.
340 - do not override $Coro::idle unconditionally in Coro.pm, as other
341 modules could have provided their own idle coro already
342 (for exmaple, Coro::AnyEvent).
343 - fix Coro::Util::gethost* functions.
344 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
345
3465.21 Wed Dec 16 07:19:51 CET 2009
347 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
348 together.
349 - add some examples on how to combine other event loops with Coro in
350 Coro::AnyEvent, and how to run it (and not to block). Seems to be
351 the most common source of confusion.
352 - try to catch people naively blocking in an event callback.
353 - work around the perl filehandle bug issue in conjunction with
354 older common::sense (as indirectly pointed out by ZSystem).
355 - clarify the "not from signal handlers" section.
356
3575.2 Sun Oct 4 14:54:24 CEST 2009
358 - Coro::Storable destroyed the prototypes of the functions it wrapped.
359 - export rouse_cb and rouse_wait by default now.
360 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
361 - new method $state->swap_sv.
362 - added section on "windows process emulation" to the manpage,
363 after a not-so-fruitful (nor-friendly) "discussion" with chip
364 salzenberg (discussion implies arguments, but his only arguments
365 were ad-hominems, one wonders why he started it in the first
366 place). I hope this explains it well enough for him to understand,
367 and maybe well enough for others to understand.
368 - use common::sense everywhere now.
369 - idle callbacks are no longer supported, use idle coros instead.
370 - print a thread listing when a deadlock is detected.
371
3725.17 Sat Aug 22 23:09:31 CEST 2009
373 - work around a bug in the perl debugger causing crashes
374 when running under the debugger by marking _pool_handler as nodebug.
375 - speed up Coro::async considerably.
376 - try some hacks to get netbsd to work "more often" - their broken
377 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
378 - convert Coro to AE 5.0 API.
379
3805.162 Tue Jul 28 04:04:03 CEST 2009
381 - perl 5.8.2 is now minimum requirement.
382 - skip t/19_handle.t on broken windows perls.
383
3845.161 Wed Jul 22 04:47:38 CEST 2009
385 - Coro::AnyEvent::poll could have a different prototype when EV was
386 used as backend (analyzed by Tatsuhiko Miyagawa).
387 - Coro::AnyEvent errornously initialised the event loop when loaded,
388 not on demand.
389 - try to workaround rare */t/01_unblock.t failures.
390
3915.16 Tue Jul 21 01:44:37 CEST 2009
392 - Coro::AnyEvent failed to hook into the event loop
393 when no threads had been readied between detecting
394 the event loop and actually running it.
395 - considerably speed up Coro::Select by taking avdantage
396 of AnyEvent > 4.8 and some other optimisations.
397 - implement paragraph readline mode in Coro::Handle
398 (based on patches by Zsbán Ambrus).
399 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
400 and analyzed by Yasuhiro MATSUMOTO).
401 - clarified libcoro license and copyright.
402 - someone stole my EXTRA_META!!!
403 - implement Coro::Select::patch_pp_sselect and it's brother,
404 for hardcode select overriding.
405
4065.151 Mon Jul 6 05:41:57 CEST 2009
407 - backport to windows process emulation code again (patch by
408 Yasuhiro MATSUMOTO).
409 - slightly update Coro::MakeMaker.
410
4115.15 Tue Jun 30 10:28:06 CEST 2009
412 - deprecate Coro::Socket, document how to get ipv6 support via
413 AnyEvent::Socket instead.
414 - implement signal->wait ($cb) interface, similar to semaphores.
415 - work around SvOK not supporting getmagic, so we have to getmagic
416 to test for undef :/ (reported by Matthias Waldorf).
417 - load Coro::AnyEvent in all modules using AnyEvent.
418 - work around perl corrupting our internal data structures,
419 reported by Tokuhiro Matsuno.
420 - enable per-coroutine real and cpu time gathering
421 (Coro::State::enable_times).
422
4235.14 Wed Jun 24 01:37:48 CEST 2009
424 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
425 as this seems to have been a difficult concept (poll, sleep, idle,
426 idle_upto).
427 - add Coro::AnyEvent::readable/writable functions.
428 - clarify Coro::EV/Event/AnyEvent manpages.
429 - free per-thread global scalars in the thread calling ->cancel, to
430 avoid crashes when $_, $@ etc., are magical but some of those
431 had already been freed.
432 - "unexperimentalise" the callback interface for Coro::Semaphore.
433 - speed up ready queue management/context switching by using a linked
434 list instead of an array (~5-10%).
435 - implement "watch" command in Coro::Debug shells.
436 - for fun, implement time-slicing as an example in the manpage.
437 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
438 Coro::Event, use the normal AnyEvent handling instead of dieing
439 (the same is true for Coro::Handle).
440 - properly document Coro::EV::timed_io_once.
441 - avoid unneccessary ->cancel calls in Coro::Handle.
442 - maybe make it work on mingw32 with win32 backend
443 (based on patch by Yasuhiro Matsumoto).
444
4455.132 Fri May 29 09:00:39 CEST 2009
446 - do not keep a reference to the argument itself in
447 Coro::Semaphore::guard, as it could change later.
448 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
449 should support a prepare callback.
450
4515.131 Mon Mar 16 23:20:37 CET 2009
452 - implement and document Coro->suspend, Coro->resume.
453 - fix Coro::Select implementation to not (often) close
454 the passed file descriptors (testcase provided by pippijn).
455
4565.13 Mon Dec 15 21:51:42 CET 2008
457 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
458 - don't set diehook to C<undef> but instead to NULL, to avoid
459 spurious warnings.
460 - fix a lot of bugs in Coro::SemaphoreSet.
461 - Coro::SemaphoreSet will less often create a semaphore needlessly.
462 - add Coro::SemaphoreSet::count and wait methods.
463 - take advantage of the new Guard module.
464 - deprecate Coro::guard.
465 - try to fix the dreaded 01_unblock tests once more. I hate it when
466 testsuites need more fixing than the code they are supposed to test.
467 - croak in more cases when a required callback isn't resolvable.
468 - fix some minor issues in Coro::State->call/eval.
469 - use current coroutine context instead of a temporary one
470 when temporarily switching to another coroutine.
471 - do not call C-level on_destroy handlers during global destruction,
472 to avoid needless segfaults.
473
4745.12 Sun Dec 7 13:30:38 CET 2008
475 - add default config for MirOS, which seems to be a bug-to-bug
476 compatible fork of openbsd ("world domination by releasing
477 openbsd cvs before the openbsd folks do it" or so :).
478 - free_padlist did destroy the names pad, not good, but didn't
479 seem to bother perl - this could fix issues such as eval ""
480 inside a function called from multiple coroutines.
481 - use a different method to detect destruction time.
482 - be more careful when freeing padlists just before global
483 destruction.
484 - fixed and expanded the call/cc example.
485 - renamed _terminate to _coro_run.
486 - new method Coro::Channel->shutdown.
487 - try pthreads on openbsd <4.4 (broken sigaltstack, will
488 pthreads fare better?).
489 - be less picky about destroying "a" running coroutine.
490
4915.11 Tue Nov 25 21:49:05 CET 2008
492 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
493 working code with failed assertions, introducing more bugs than
494 it fixes, requiring elaborate workarounds :(
495
4965.1 Mon Nov 24 08:54:59 CET 2008
497 - wrote a small introductory tutorial - Coro::Intro.
498 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
499 - Coro::Select did errornously dup the file descriptors
500 and didn't work with all AnyEvent backends.
501 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
502 LWP data transfers.
503 - disassociate c contexts from coro objects - this is agruably more
504 correct, but mostly allows sharing of cctxs between coro and state
505 objects, for added memory savings and speed increases.
506 - bumped $Coro::POOL_RSS up to 32kb by default.
507 - no longer set the optype to OP_CUSTOM, as B::* understandably
508 doesn't like this very much (and we *are* a type of entersub).
509 - implement state cloning, just to prove that call/cc can be done.
510 - automatically load Coro::AnyEvent in Coro::Handle.
511 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
512 do not have this method (and don't need it either).
513 - speed up generic anyevent methods in Coro::Handle by using rouse
514 callbacks.
515 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
516 others. It also makes the debugger happier, as you can trace
517 through the idle threads now.
518 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
519 - eg/event was pretty broken.
520 - better 5.8.6 compatibility.
521
5225.0 Thu Nov 20 10:35:05 CET 2008
523 - NEW ARCHITECTURE: use the latest 4.x version if you experience
524 stability issues.
525 - bump API version to 7 - all dependents must be recompiled.
526 - removed timed_* functions - they were not being used anyways
527 and should be replaced by a more generic mechanism -
528 and were annoying to support anyways :)
529 - removed SemaphoreSet's waiter method - use sem method instead.
530 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
531 - async_pool did free a scalar value twice
532 ("Attempt to unreference...").
533 - fix a longstanding bug where calling terminate on a coro that
534 was waiting for a semaphore that was just becoming available
535 would cause a deadlock (semaphore would get into a state where
536 it was available but waiters were still blocked).
537 - calling throw on a coroutine that is waiting for a semaphore will
538 no longer make it acquire the semaphore (and thus leak a count).
539 - perl's process emulation is now not even theoretically supported
540 anymore.
541 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
542 conversion of callback-style to blocking-style.
543 - new methods $coro->schedule_to and ->cede_to, to specifically
544 schedule or cede to a specific coroutine.
545 - new function Coro::Semaphore::wait.
546 - use named constants in Coro::Channel (Richard Hundt).
547 - directly patch the entersub opcode calling SLF functions (cede,
548 transfer and so on). this does speed up context switching, but
549 more importanly, it frees us from the hardcoded behaviour of
550 entersub, so we might actually be able to return something from
551 those functions and atcually create new ones.
552 - take advantage of __builtin_frame_address on gcc.
553 - expose THX in coroapi (not sure whether this was a wise decision,
554 as "threaded" perls are running at half speed anyways).
555 - implement execute_slf (schedule-like-function) interface that makes
556 it possible to implement schedule-like-functions in XS.
557 - use new SLF interface to massively speed up Coro::EV by roughly a
558 factor of two.
559 - used new SLF interface to massively speed up Coro::Semaphore by a
560 factor of three.
561 - used new SLF interface to speed up Coro::AIO by roughly a factor of
562 four and reduce its memory usage considerably.
563 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
564 for a nice speedup and vastly more correct behaviour. Also implement
565 a new method "sem" to get at the underlying semaphore object.
566 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
567 (in comparison) 20-40% speedup.
568 - used new SLF interface to reimplement Coro::Signal gaining
569 some unknown (because I was too lazy), but certain, speedup, and also
570 making signals reliable for the first time.
571 - used new SLF interface and other optimisations to speed up async_pool
572 by a factor of two. It also doesn't rely on perl's exception mechanism
573 to exit anymore. The overhead for terminating an async_pool, coro over
574 a normal async is now very small.
575 - sped up coroutine creation/destruction by 40%.
576 - forgot to include Coro/libcoro/README in the dist for all these years.
577 - work around a freebsd pthreads bug (manual testcancel is required as
578 pthread_cond_wait isn't a cancellation point on freebsd).
579 - use new rouse functions to speed up and simplify Coro::BDB.
580 - make "prefer perl native functions" work with threaded perls.
581 - condense Coro::Debug ps output, hint at v and w flags.
582 - (libcoro) lots of minor cleanups and portability improvements.
583
5844.914 Wed Nov 19 12:54:18 CET 2008
585 - fix a disastrous bug in the readline optimisation
586 introduced in 4.801.
587
5884.913 Sat Nov 15 07:58:28 CET 2008
589 - async_pool did free a scalar value twice
590 ("Attempt to unreference...").
591
5924.912 Thu Nov 13 18:31:23 CET 2008
593 - minor cleanups.
594 - use much larger stacks on linux and perl < 5.8.8.
595 - Coro::Debug::new_unix_server did not unlink the socket
596 when destroyed.
597
5984.911 Tue Nov 11 04:26:17 CET 2008
599 - "port" to threaded perls.
600
6014.91 Mon Nov 10 05:36:38 CET 2008
602 - the ->throw exception object no longer leaks.
603 - creating a new cctx leaked a scopestack entry (memleak).
604 - new coroutines didn't get created with a zero flags field
605 (unknown impact).
606 - calling ->throw on a not-yet-started coroutine should now work
607 instead of being ignored.
608 - ->throw is now supported on Coro::State objects.
609 - clean up cctx creation code a bit.
610 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
611
6124.9 Sat Nov 8 17:45:27 CET 2008
613 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
614 - (libcoro) no longer leak threads in the experimental pthread backend,
615 also speed it up considerably.
616 - (libcoro) do not rely on makecontext passing void *'s unscathed.
617 - fix compiletime dependencies on libcoro in the Makefile.
618 - cctx_count wasn't always updated properly.
619 - Coro::State::cctx_stacksize wasn't applied correctly.
620 - new function Coro::State::cctx_max_idle.
621 - the default max number of idle C contexts is now 4.
622 - (libcoro) try harder to get _setjmp/_longjmp.
623 - (libcoro) cleanup and extend the libcoro API to officially
624 allow the creation of empty source contexts.
625 - very experimental workaround for the totally broken netbsd platform.
626 - tried to hack around openbsd bugs.
627
6284.804 Wed Nov 5 16:36:00 CET 2008
629 - Coro::Debug::new_unix_server would not create a non-blocking listening
630 socket, sometimes causing freezes.
631 - (libcoro) fix misaligned stack points for setjmp and assembly
632 methods, which can cause crashes on x86/x86_64 with a sufficiently
633 aggressive compiler.
634 - new function: Coro::Debug::new_tcp_server.
635 - move ->throw into the Coro class because it only works on coro objects.
636
6374.803 Mon Nov 3 17:16:12 CET 2008
638 - (libcoro) use a global asm statement to become independent of gcc
639 otpimisations for CORO_ASM (thanks to pippijn for the idea).
640 - try to workaround yet another broken bsd, this time dragonfly.
641
6424.802 Thu Oct 30 10:56:12 CET 2008
643 - support -fno-omit-frame-pointer on x86 with the assembly method.
644 - tune 01_unblock.t tests a bit.
645
6464.801 Wed Oct 22 18:33:37 CEST 2008
647 - improve readline speed for very long "lines".
648 - backport to 5.8.8.
649
6504.8 Thu Oct 2 13:34:40 CEST 2008
651 - new function Coro::AIO::aio_wait.
652 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
653 - greatly speed up and reduce memory usage of Coro::AIO requests.
654 - implement some other µ-optimisations.
655
6564.749 Mon Sep 29 14:40:12 CEST 2008
657 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
658
6594.748 Sat Sep 27 14:03:19 CEST 2008
660 - implement, but do not document, PerlIO::cede(granularity).
661 - Coro::Storable forgot to wrap Storable::pstore.
662 - work around the multitude of leaks and memory corruption
663 bugs in PerlIO::via by using our own C-level perliol. As a side
664 effect, Coro::Storable is now much, much, much faster.
665
6664.747 Tue Sep 23 01:59:41 CEST 2008
667 - fix a per-cv memleak (one empty array was leaked per
668 code reference).
669 - avoid a crash in coro->call|rss when the coroutine was already
670 destroyed (most noticably when using Coro::Debug::ps :)
671 - also protect *Storable::FILE.
672 - push up default storable granularity to 20ms.
673
6744.746 Sun Sep 21 03:22:20 CEST 2008
675 - be more insistent on locking Storable against reentrancy
676 in Coro::Storable.
677 - move swap_def?v and throw to Coro::State, as documented.
678
6794.745 Thu Jul 24 00:14:38 CEST 2008
680 - remove debugging code related to MgPV_nolen_const, also try to
681 make it compile with perl 5.8.6 (yes, apple apparently loves
682 outdated software). Reported by John S.
683
6844.744 Tue Jul 8 22:06:35 CEST 2008
685 - correctly provide default DIE/WARN handlers as documented.
686 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
687 implementations inside perl work fine for us.
688
6894.743 Mon Jun 16 00:21:57 CEST 2008
690 - when using Coro::EV without running EV::loop it could
691 result in busy-waiting for events, this has been fixed.
692 - reduce codesize and improve performance by using EV_DEFAULT_UC.
693
6944.742 Sat May 31 14:10:21 CEST 2008
695 - implement a workaround for (some) perl <5.8.8 versions.
696 - require EV 3.3+.
697
6984.741 Fri May 30 23:33:09 CEST 2008
699 - tell netbsd how utterly broken their imitation of an OS is
700 and refuse to build by default if pthreads are in use.
701 - switch to "s" method on all bsd's by default, as their ucontext
702 stuff seems just too broken.
703 - fix a bug in Coro::Select.
704
7054.74 Thu May 29 20:05:31 CEST 2008
706 - do not test Coro::LWP for lack of dependencies.
707 - do not test Coro::Select for lack of working perls.
708
7094.73 Thu May 29 2008
710 - fix a bug in Coro::EV which would cause it to block despite
711 there being runnable coroutines.
712 - sprinkle "no warnings" freely over everything, also suppress
713 warnings for some other modules.
714 - fix typo in WSAEWOULDBLOCK.
715
7164.72 Sun May 25 05:14:36 CEST 2008
717 - tweak META.yaml a bit, unfortunately, there is no documented way
718 to have optional dependencies with CPAN. doh :(
719 - avoid running some tests on windows because they would fail due to
720 perl bug (broken fork, broken pipes...).
721 - work around perl on windows bugs where perl returns undocumented
722 error codes for sysread, syswrite etc. by taking advantage
723 of AnyEvent's workaround for that problem.
724 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
725 a common perl implementation bug on windows.
726 - use unix domain sockets in testsuite to work around
727 common perl implementation bugs on widows (they are emulated by
728 tcp sockets on windows. ugh.)
729
7304.71 Sat May 24 20:01:27 CEST 2008
731 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
732 - take advantage of async name resolution of AnyEvent::Util.
733 - work around brutal inet_aton override in Coro::LWP.
734 - take advantage of the readyhook in Coro::EV, for smoother
735 scheduling.
736
7374.7 Sun May 11 00:32:19 CEST 2008
738 - completely reworked the Coro manpage.
739 - added Coro::AnyEvent, generic event loop integration.
740 - implement cancel, ready and kill commands in Coro::Debug.
741 - document find_coro in Coro::Debug.
742 - incompatible change: rename has_stack to has_cctx.
743 - Coro::AIO and Coro::BDB no longer force event model detection,
744 use AnyEvent::AIO and AnyEvent::BDB.
745
7464.6 Sat Apr 26 10:05:14 CEST 2008
747 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
748 by the Coro module. It was a mistake to have it in the first place.
749 - (experimental) support for activestate perl 5.10 (method "w").
750 - (experimental) support for strawberry perl (method "a").
751 - coro_sigelem_set did not return a value although it had to,
752 actual impact unknown.
753
7544.51 Mon Apr 14 13:28:27 CEST 2008
755 - make it compile again on 5.8.
756
7574.50 Thu Apr 10 09:43:17 CEST 2008
758 - I did it twice! (see 4.49).
759
7604.49 Sun Apr 6 21:23:31 CEST 2008
761 - grr, instead of compiling the recent changes on 5.10 only they
762 were compiled on 5.8 only.
763
7644.48 Sun Apr 6 20:36:46 CEST 2008
765 - allow coroutine switches during eval's under 5.10.x, as it seems
766 the parser is a per-interpreter option now, so this is safe
767 (this might fix the odd crashing bug).
768 - drop support for 5.9.x versions: they are dead, jim.
769
7704.47 Sun Apr 6 00:37:52 CEST 2008
771 - force cctx allocation on API calls: we know we need to force one
772 and gcc actually manages to confuse our heuristic nowadays,
773 leading to crashes and worse.
774 - document force_cctx.
775
7764.46 Fri Apr 4 22:05:43 CEST 2008
777 - upgrade libcoro, resulting in pthread-backend (which was only created
778 to fulfill the rules of the programming languages shootout).
779
7804.45 Thu Mar 13 11:55:36 CET 2008
781 - fix a file leaking bug in eg/mhyttpd that would allow
782 downloading of any file (reported by oesi).
783 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
784 (also add testcase).
785 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
786 apparently having loads of fun with that).
787 - implement $state->swap_defsv, ->swap_defav and document ->throw.
788
7894.4 Wed Feb 13 16:44:29 CET 2008
790 - only assume .cfi pseudo isns exist on GNU/Linux.
791 - add get_timed method to Coro::Channels.
792 - fixed Coro::Debug manpage.
793 - perl 5.11 compatbility improvement based on patch by
794 Andreas König.
795
7964.37 Sun Jan 20 11:25:23 CET 2008
797 - soften the check for an active parser for perl 5.10 (avoiding
798 "Coro::State::transfer called while parsing" in many cases).
799
8004.36 Sun Jan 13 10:53:56 CET 2008
801 - reset diehook when terminating from an async_pool as to not
802 trigger any __DIE__ handlers.
803
8044.35 Sun Jan 13 04:14:13 CET 2008
805 - "bt" debug command now displays any exceptions
806 from longmess and also skips the innermost
807 stackframes, giving more useufl output.
808 - allow backtraces in coroutines blocked in Coro::EV,
809 at a <1% speed hit.
810 - handle localising of $SIG{__WARN__} and __DIE__
811 properly (with a proper amount of dirty hacking).
812
8134.34 Sat Dec 22 17:49:53 CET 2007
814 - upgrade to EV version 2.0 API.
815
8164.33 Mon Dec 17 08:36:12 CET 2007
817 - make Coro::AIO etc. loadable in the absence of EV.
818
8194.32 Mon Dec 17 07:46:02 CET 2007
820 - majorly improved Coro::Handle's performance with Coro::EV.
821 - implemented the until now mythical Coro::BDB module.
822 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
823
8244.31 Wed Dec 5 12:32:39 CET 2007
825 - remove warn statement form Coro::Util.
826
8274.3 Tue Dec 4 20:33:14 CET 2007
828 - calls to the idle function could cause stack corruption
829 when the stack changed.
830 - do no longer rely on the presence of EV::DNS if EV is used
831 (because it is gone), but instead take avdantage of EV::ADNS
832 if available.
833 - add ($) prototypes to all functions in Coro::Storable.
834 - use a conventional (safer) idle callback in Coro::EV.
835 - do accept quickly in Coro::Debug to avoid endless loops.
836
8374.22 Fri Nov 30 16:04:04 CET 2007
838 - really use optimised versions for Event and EV in Coro::Util
839 and Coro::Handle.
840
8414.21 Sun Nov 25 10:48:59 CET 2007
842 - fix a spurious memory read.
843 - Coro::EV no longer keeps the eventloop "alive".
844
8454.2 Fri Nov 9 20:47:05 CET 2007
846 - enable/disable tracing from a new coroutine, not a pooled one.
847 - fix a memleak in Coro::Event.
848 - removed killall call from fork_eval.
849 - made sure store_fd is already loaded so that fork_eval
850 does not have to parse autoload in each subprocess.
851 - only use assembly method if -O switch is in $Config{optimize}.
852 - add (optional) Coro::EV module, so far the best event loop module
853 directly supported by Coro.
854 - if the event model is EV, use EV::DNS to resolve
855 stuff in Coro::Util.
856 - don't get confused by multiple event notifications in Coro::Handle.
857 - initial support for EV (libevent interface).
858 - require Event and EV using configure_requires, to force their existance.
859
8604.13 Wed Oct 24 07:26:45 CEST 2007
861 - add Coro::Storable::blocking_thaw.
862 - use a vastly more complicated technique to localise
863 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
864 - use a coroutine for the idle callback Coro::Event,
865 instead of running Event in the current coroutine context.
866 This also catches recursive invocations.
867 - actually report fork errors in gethostbyname and inet_aton.
868
8694.11 Thu Oct 11 02:40:24 CEST 2007
870 - port to threaded perls.
871
8724.1 Thu Oct 11 02:38:16 CEST 2007
873 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
874 be local to each coro (see Coro::State).
875 - incompatible change: for very deep reasons, cede and cede_notself
876 cannot return anything, so nothing will be returned.
877 - possibly bring back 5.10 compatibility (untested).
878 - work around stupid (and wrong) warning on 5.10 :(.
879 - overlay the saved state over the context stack. This saves
880 a few hundred bytes per coroutine on average and also
881 speeds up context switching a bit.
882 - further tune default stack sizes.
883 - (more) correctly calculate stack usage in coro_rss.
884 - Coro::Storable::blocking_* did not properly lock
885 resulting in races between coroutines.
886 - added Coro::Storable::guard.
887 - stopping to trace a coroutine could destroy the cctx of
888 an unrelated coroutine.
889 - explain the relationship between Perl and C coroutines in
890 more detail in Coro::State.
891 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
892 causing a fork per resolve. This also affected Coro::Socket.
893 - switch to a separate stack in $coro->call/eval to avoid
894 invalidating pointers.
895
8964.03 Sat Oct 6 21:24:00 CEST 2007
897 - added Coro::throw method.
898 - minor code cleanups.
899
9004.02 Sat Oct 6 02:36:47 CEST 2007
901 - fix a very minor per-coroutine memleak (a single codereference).
902 - fixed a bug where the currently in-use c context would be freed
903 prematurely (can happen only when programs change the stacksize
904 or use tracing).
905 - tracing can no longer keep a coro alive after it terminated.
906 - do static branch prediction in the common path for gcc. gives
907 about 2-5% speed improvement here.
908
9094.01 Fri Oct 5 22:10:49 CEST 2007
910 - instead of recreating *a* standard output handle we simply
911 use STDOUT, which is faster and hopefully more robust.
912
9134.0 Fri Oct 5 12:56:00 CEST 2007
914 - incompatibly changed Coro::Storable::freeze.
915 - major new feature: added Coro::Debug, for interactive coroutine
916 debugging, tracing and much more.
917 - major bug fix: unbelievable, but true: $_, $/ and many other
918 "saved" variables actually weren't being saved. This has been fixed,
919 of course, while increasing performance while losing all the save
920 flags.
921 - save flags are gone, and all the api functions dealing with them.
922 - added Coro::Semaphore::adjust.
923 - added Coro::Util::fork_eval.
924 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
925 - added Coro::killall.
926 - reduce initial stack sizes to allow for "micro-coroutines".
927 - better async_pool resource management, moved parts of async_pool
928 handling to XS (major speed improvement).
929 - actually croak before modifying important data structures.
930 - refuse to transfer while compiling.
931 - possibly support eval EXPR better now.
932 - enable assembly per default on linux+bsd x86+amd64.
933 - all internal members were renamed _something for easier subclassing.
934 - many minor tweaks.
935
9363.63 Wed May 16 14:10:06 CEST 2007
937 - implement handcoded assembly for x86/amd64 SVR ABI.
938
9393.62 Fri Apr 27 21:36:06 CEST 2007
940 - upgrade libcoro (which might set unwind info correctly).
941 - change default on linux to setjmp/longjmp.
942
9433.61 Thu Apr 19 12:36:18 CEST 2007
944 - Coro::Storable caused an endless loop when thawing invalid
945 pst's sometimes.
946 - use a Semaphore in Coro::Storable, as Storable doesn't
947 seem to be reentrant (although it is documented to
948 be threadsafe...).
949 - fix Coro::Signal to bring back the original unreliable
950 but stateful semantics.
951 - fixed a lot of typos in Coro.pm (patch submitted by David
952 Steinbrunner, which applied flawlessly).
953
9543.6 Sat Apr 14 17:13:31 CEST 2007
955 - added some bugfixes to get eg/myhttpd working again.
956 - added Coro::Storable for often-cede'ing freeze/thaw.
957 - try to do a clean exit when a coroutine calls exit
958 (EXPERIMENTAL).
959 - got rid of indirect call through _coro_init.
960 - updated the partly antique examples in eg/ to
961 work again and be a bit less magic, too.
962 - fixed Coro::Signal semantics to work as documented again.
963
9643.55 Sun Mar 25 01:20:47 CET 2007
965 - add SAVE_DEFFH to save the default filehandle and enable
966 it by default.
967 - finally move socket-operations from Coro::Socket to Coro::Handle
968 to be able to unblock foreign sockets.
969 - add Coro::State::save_also and guarded_save.
970 - add count accessor to Coro::Semaphore.
971 - add Coro::State::cctx_stacksize.
972 - just for the fun of it, do not rely on implicit context,
973 which can dramatically improve performance, but people
974 using windows-process-emulation perls do not care much about
975 performance.
976
9773.51 Sun Mar 4 14:18:04 CET 2007
978 - fixed a problem when you weakened references to Coro::State's
979 (patch by Yuval Kogman).
980
9813.501 Wed Feb 28 12:44:07 CET 2007
982 - rename some global symbols as macosx from hell redefines
983 them without asking.
984
9853.5 Tue Feb 13 20:22:53 CET 2007
986 - do AnyEvent model detection earlier, avoiding problems
987 caused by first using AnyEvent and later Coro::Event.
988 - implement and document Coro::Event event objects.
989 - fix a potential problem in Coro::Event causing crashes.
990 - initialise PL_comppad when creating a new coroutine,
991 avoids crashes on early coro destruction.
992
9933.41 Mon Jan 22 19:19:49 CET 2007
994 - readline on Coro::Handle did not support undefined $/,
995 nor did it deliver partial lines on EOF or error.
996 - implement malloc fallback for stack allocation because
997 stupid broken idiotic OSX has a stupid broken
998 idiotic fits-the-whole-os mmap "implementation" and
999 my dick feels longer if Coro is portable even to
1000 obsolete platforms.
1001
10023.4 Fri Jan 19 21:52:54 CET 2007
1003 - remove t/09_timer.t, as it isn't really testing much
1004 but was rather flaky in practise.
1005 - async_pool coro would keep arguments and callback alive until
1006 it was reused.
1007 - cancellation of a coroutine could cause spurious idle calls
1008 in cede_notself.
1009
10103.3 Sat Jan 6 03:45:00 CET 2007
1011 - implement $coro->on_destroy.
1012 - Coro::Event blocking semantics have been changed,
1013 documented and - hopefully - improved.
7 - fix nice adding, not subtracting, from priority. 1014 - fix nice adding, not subtracting, from priority.
8 - fix ->prio and api_is_ready (patch by Mark Hinds). 1015 - fix ->prio and api_is_ready (patch by Mark Hinds).
1016 - fixed an assert ("... == prev__cctx->idle_te")
1017 that could errronously trigger.
1018 - fix various large and small memleaks.
1019 - use a (hopefully) more stable cancel implementation
1020 that immediately frees the coroutine data.
1021 - cede/cede_notself return a status now.
1022 - added Coro::guard function.
1023 - added a global coroutine pool for jobs (on my machine,
1024 I can create and execute 48k simple coros/s with async,
1025 and 128k coros with async_pool).
1026 - Coro::AIO now uses the coroutine priority as io priority.

103.2 Fri Dec 22 05:07:09 CET 2006 10283.2 Fri Dec 22 05:07:09 CET 2006
11 - improve portability to slightly older perls. 1029 - improve portability to slightly older perls.
12 - use cleaner coroutine destruction. 1030 - use cleaner coroutine destruction.
13 - simplify configuration for users. 1031 - simplify configuration for users.
