1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO. 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: maybe implement a default message channel, very much like Erlang 4TODO: channel->maxsize(newsize)?
5 (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?
7TODO: croak when async_pool tries to run canceled thread?
7 8
84.35 9 - work around assertion failure in perl_destruct on 5.24
10 (analyzed by Dave Mitchell).
11
126.5 Wed Jun 22 22:23:50 CEST 2016
13 - swap_sv swapping order was not symmetrical, causing
14 wrong swaps when swap_sv was used multiple times on the
15 same sv in the same thread.
16 - swap_sv calls can now be undone by calling it again
17 with the same variables.
18 - swap_sv calls will now be undone in async_pool threads.
19 - split Coro::Semaphore::up/adjust into separate xs functions
20 for better error reporting, at slight codesize increase.
21 - (libcoro) arm assembly support, please test and report.
22 - adjust to PL_savestack changes in perl 5.24 (adapted from
23 the debian patch, which unfortunately gets it wrong).
24
256.49 Sat Oct 17 01:40:12 CEST 2015
26 - throwing an exception to a thread waiting in
27 Coro::Handle using Coro::EV did not stop the watchers,
28 causing the next call to fail (testcase by Martin Pritchard).
29 - bump minimum perl version to 5.10.
30
316.48 Sun Oct 4 19:03:51 CEST 2015
32 - fix memory leak when Coro::Handle uses Coro::EV internally
33 (testcase by Sten Sten).
34 - update code to libev 4 API (internally, Coro still used the
35 version 3 API calls).
36 - remove unused hv_sig.
37
386.47 Sat Jul 11 03:58:20 CEST 2015
39 - swap_svs - NVs can be in the SV head beginning with 5.20.
40
416.46 Tue Jun 30 14:36:30 CEST 2015
42 - restore portability to perls with windows fork emulation
43 (patch by Petr Písař).
44
456.45 Tue Jun 30 01:40:08 CEST 2015
46 - restore portability to perl 5.16 and below.
47
486.44 Tue Jun 30 00:41:54 CEST 2015
49 - avoid segfaulting (or worse) when tracing a canceled thread.
50 - the Event module silently broke it's public hook API, causing
51 failures on perls compiled with -Duselongdouble. Requiring
52 the latest version of Event because I don't know which release
53 changed this (it's not mentioned in the ChangeLog).
54 - allow xs level enterleave hooks via CoroAPI.
55
566.43 Thu Jun 4 15:38:14 CEST 2015
57 - use stability canary.
58 - port to stableperl-5.22.0-1.001.
59 - update libecb.
60
616.42 Wed Feb 11 20:29:52 CET 2015
62 - Coro::SemaphoreSet->try did not actually work (analyzed by
63 SATO Kentaro).
64 - upgrade libecb to be C11 compliant.
65
666.41 Sat Sep 6 22:08:46 CEST 2014
67 - restore portability to perl 5.8.x.
68 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
69 up some memory, but fixes "use feature" and similar modules
70 when used inside a Coro.
71 - allow zero as argument to Coro::Channel to mean the same thing
72 as no argument. this works with older versions as well,
73 but wasn't legal until now.
74 - slightly better c header file detection.
75
766.39 Mon Jun 2 00:00:08 CEST 2014
77 - work around more incompatible changes in 5.20.
78
796.38 Sun Jun 1 21:54:23 CEST 2014
80 - check that perl slots actually have enough space to hold
81 interpreter variables.
82 - untested port to perl 5.19 (64 bit tmps indices) (reported
83 by Andreas König).
84 - croak when cancel is called without a thread context.
85
866.37 Tue Mar 4 13:27:33 CET 2014
87 - *sigh*, removed leftover debugging code from debugging a
88 perl bug, of all things.
89
906.36 Tue Mar 4 07:11:59 CET 2014
91 - semaphores would not clear the destroy hook when interrupted
92 by ->throw, causing segfaults or worse.
93 - ->throw on a thread waiting for a semaphore did not acquire
94 the semaphore, but also didn't wake up other waiters,
95 possibly causing a deadlock.
96 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
97 to report a full stacktrace, which should help find out
98 where the actual call is.
99 - "atomically" destroy data in slf_destroy, because it is
100 the right thing to do, just in case.
101 - disable ecb.h libm dependency, to compile on ancient systems
102 or under adverse conditions.
103
1046.33 Mon Nov 18 11:26:27 CET 2013
105 - do not crash when freeing padlists with holes (in 5.18).
106 - tentative SVt_BIND 5.19 port/fix.
107
1086.32 Tue Nov 5 15:35:35 CET 2013
109 - use a new algorithm to derive padlists for perl 5.18. The old
110 one could lead to 0-pointer accesses inside perl (reported
111 by Darin McBride).
112
1136.31 Thu May 9 07:39:48 CEST 2013
114 - Coro::AIO requests would crash if the thread was ready'd
115 while the request was ongoing.
116
1176.29 Wed May 8 02:55:18 CEST 2013
118 - when an on_destroy handler destructs the coro currently being
119 destructed a perl scalar could be accessed after being freed,
120 likely causing a crash.
121
1226.28 Wed Mar 6 06:58:02 CET 2013
123 - clean remnants of existing __DIE__ and __WARN__ handlers so
124 they lose their magic and will not cause segfaults later
125 (testcase by Andrey Sagulin).
126 - improved Coro::State documentation a bit.
127 - Coro::Debug::command now flushes the output.
128 - add hack detection code for x32 abi, because the braindead slugs
129 who designed that made it look exactly like x86_64 without
130 providing proper compile time symbols to test for it. as a result,
131 this detection cannot work reliably.
132 - valgrind stack registering was broken.
133 - do not rely on Time::HiRes anymore in Coro::Debug.
134
1356.23 Fri Dec 7 23:36:37 CET 2012
136 - use experimental fiber implementation on native windows
137 perls.
138 - use sizeof (void *) as multiplication factor for stack sizes,
139 to accomodate the totally braindamaged microsoft 64 bit "os".
140 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
141 activeperl 5.16 crashes when PerlIO_define_layer is called due
142 to some bug in the perl dll, strawberry perl at least passes
143 the testsuite.
144 - implement Coro::Handle->peeraddr/host/port, for slightly
145 improved compatibility with LWP.
146 - implement 5.17 compatibility by almost blindly applying a
147 good-looking patch by Father Chrysostomos.
148 - move stack management functions into libcoro 3.
149 - libcoro version 3 "released".
150 - support magic values as timed_io_once args.
151 - recommend AnyEvent 7+ or EV 4+, also require EV
152 version 4 or newer for Coro::EV.
153
1546.10 Tue Oct 9 01:14:27 CEST 2012
155 - updated ecb.h, it had a typo that caused it to not compile on many
156 big endian systems (reported by many people).
157 - disable memory fences in ecb.h to improve portability.
158
1596.09 Sat Oct 6 23:25:02 CEST 2012
160 - Coro::EV I/O watchers were not interruptible by exceptions
161 (Coro::State::throw) (testcase by sten).
162 - ->throw now puts threads into the ready queue, as this seems to
163 be expected by existing code, and code that doesn't cope with spurious
164 wakeups needs fixing anyway.
165 - use fd -1 in mmap.
166 - cast I32 to int in error message printf.
167 - warn about broken so-called "hardened" kernels.
168
1696.08 Fri Apr 13 12:05:47 CEST 2012
170 - be more aggressive about exiting like perl does - formerly,
171 exiting from the non-main thread would not execute END blocks.
172
1736.07 Fri Nov 11 21:21:48 CET 2011
174 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
175 - update ecb.h.
176
1776.06 Mon Aug 8 23:59:48 CEST 2011
178 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
179 backend, which is an order of magnitude slower. unfortunately, cygwins
180 pthread implementation isn't very complete either, so allocate the stack
181 twice just to be sure.
182 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
183 in its ithreaded perl - best recompile cygwin and use the 'w'indows
184 backend for much better performance. also disable ithreads for
185 even better performance...).
186
1876.05 Thu Aug 4 21:36:36 CEST 2011
188 - blush, condvar values would not be propagated from send to recv anymore
189 (reported by Chip Salzenberg).
190 - use exponential increase for the readline buffer length in
191 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
192
1936.04 Wed Aug 3 17:15:45 CEST 2011
194 - use even more efficient and more compatible condvars for
195 compatibility to AnyEvent 6.x :)
196 - more inconsequential ecb.h updates.
197
1986.03 Wed Aug 3 11:41:30 CEST 2011
199 - change how Coro patches AnyEvent condvars for compatibility to
200 AnyEvent 6.x.
201 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
202 hasn't been included.
203
2046.02 Wed Jul 13 04:35:19 CEST 2011
205 - "improve portability to Gentoo" - gentoo manages to put perl variables
206 in memory areas that are farther than 2gb apart, which the jit couldn't
207 handle and barfed. now it's just a bit slower on gentoo and similar
208 systems.
209
2106.01 Sun Jul 3 12:31:14 CEST 2011
211 - workarounds are good, but the test for whether pthreads are used
212 was not good. this one should be better.
213 - check differently whether gcc generates cfi instructions itself.
214
2156.0 Wed Jun 29 19:43:35 CEST 2011
216 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
217 destroyed and cleaned up automatically (e.g. async { schedule }).
218 - implement a JIT compiler for part of the thread switch code,
219 which gives a 50% speed improvement on threaded perls, and
220 about 4% on non-threaded perls (so threaded perls now finally
221 reach about half the speed of non-threaded perls).
222 - slightly modernise Coro::Intro, add section about rouse functions.
223 - avoid DEFSV and ERRSV, giving another 10% improvement
224 in thread switching.
225 - Coro::State->is_destroyed is now called is_zombie.
226 - implement a Coro->safe_cancel method that might fail, but
227 cancels in a "safer" way if it succeeds.
228 - add preliminary support for DEBUGGING perls.
229 - get rid of two hash-accesses when initialising a new Coro - this
230 speeds up coro creation by almost a factor of two.
231 - croak when a coro that is being cancelled tries to block
232 (e.g. while executing a guard block), instead of crashing or
233 deadlocking.
234 - use a more robust and also faster method to identify Coro::State
235 objects - speeds up everything a bit.
236 - implement Coro->cancel in XS for a 20% speed improvement, and to
237 be able to implement mutual cancellation.
238 - speed up context switches by a percent or two by more efficiently
239 allocating context stack entries.
240 - implement Coro->join and Coro->on_destroy in XS for a speedup and
241 a reduction in memory use.
242 - cancelling a coro while it itself is cancelling another coro is
243 now supported and working, instead of triggering an assertion.
244 - be a bit more crash-resistant when calling (buggy) on_destroy
245 callbacks (best effort).
246 - move on_destroy into the slf_frame, to allow extension slf
247 functions to have destructors.
248 - get rid if coro refcounting - simply crash in other interpreter
249 threads by nulling the pointers on clone.
250 - simplify warn/die hook handling when loading Coro - the convoluted
251 logic seems to be no longer neccessary.
252 - use libecb instead of our own home-grown gcc hacks.
253 - document alternatives to Coro::LWP. Please use them :)
254 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
255 sigaltstack. Really. wine suffers from it, erlang suffers from it,
256 and it's known since at least 2006.
257
2585.372 Wed Feb 23 06:14:30 CET 2011
259 - apparently mingw doesn't provide a working gettimeofday, try to
260 work around that by relying on Time::HiRes (indirectly brought to
261 my attention by Max Maischein).
262 - fix some portability issues when Time::HiRes was used.
263
2645.371 Mon Feb 21 14:36:08 CET 2011
265 - backport to windows process emulation code again.
266
2675.37 Sat Feb 19 07:49:44 CET 2011
268 - add a big "Coro thread life cycle" section to "man Coro".
269 - try a tentative workaround against the breakage that 5.13 has
270 introduced without depreciation period. sigh.
271 - no longer use Time::HiRes if gettimeofday is available, which
272 saves quite a lot of memory.
273
2745.36 Sun Feb 13 05:33:41 CET 2011
275 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
276 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
277 method call.
278 - undocument Coro::Timer::sleep and obsolete whole module.
279 - optimise Coro::Timer::timeout memory and cpu usage.
280 - slightly updated Coro::Intro for recent changes.
281 - do not initialise PL_dirty anymore.
282
2835.25 Thu Nov 11 01:08:39 CET 2010
284 - try a different approach on netbsd - netbsd 5 finally has marginally
285 working pthreads, but still broken ucontext/sigaltstack.
286 - openbsd 4.8 finally got their act together, Coro works out of the box
287 with asm, setjmp and pthreads (no change, just informational).
288
2895.24 Sat Oct 23 11:27:12 CEST 2010
290 - port to the EV 4.0 API.
291 - work around bugs in mingw32, making strawberry perl work
292 out of the box.
293 - correctly modify Coro::AIO function prototypes
294 so that they reflect the "no optional parameters" rule.
295 - "ported" libcoro to C++.
296
2975.23 Mon May 17 18:50:42 CEST 2010
298 - be more resistant to ordering changes when initialising
299 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
300 Waldorf).
301 - document that perl 5.12 deliberately removed support for cloning.
302
3035.22 Wed Apr 14 03:55:35 CEST 2010
304 - correctly return udnef on errors in Coro::Handle::read/write
305 (testcase by Marc Mims).
306 - convert Coro::Util into a "perl compatibility wrapper" - the functions
307 are less useful now, but are drop-in replacements for existing
308 functions, listing better alternatives in the documentation. This also
309 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
310 with Coro::Util::inet_aton.
311 - do not override $Coro::idle unconditionally in Coro.pm, as other
312 modules could have provided their own idle coro already
313 (for exmaple, Coro::AnyEvent).
314 - fix Coro::Util::gethost* functions.
315 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
316
3175.21 Wed Dec 16 07:19:51 CET 2009
318 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
319 together.
320 - add some examples on how to combine other event loops with Coro in
321 Coro::AnyEvent, and how to run it (and not to block). Seems to be
322 the most common source of confusion.
323 - try to catch people naively blocking in an event callback.
324 - work around the perl filehandle bug issue in conjunction with
325 older common::sense (as indirectly pointed out by ZSystem).
326 - clarify the "not from signal handlers" section.
327
3285.2 Sun Oct 4 14:54:24 CEST 2009
329 - Coro::Storable destroyed the prototypes of the functions it wrapped.
330 - export rouse_cb and rouse_wait by default now.
331 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
332 - new method $state->swap_sv.
333 - added section on "windows process emulation" to the manpage,
334 after a not-so-fruitful (nor-friendly) "discussion" with chip
335 salzenberg (discussion implies arguments, but his only arguments
336 were ad-hominems, one wonders why he started it in the first
337 place). I hope this explains it well enough for him to understand,
338 and maybe well enough for others to understand.
339 - use common::sense everywhere now.
340 - idle callbacks are no longer supported, use idle coros instead.
341 - print a thread listing when a deadlock is detected.
342
3435.17 Sat Aug 22 23:09:31 CEST 2009
344 - work around a bug in the perl debugger causing crashes
345 when running under the debugger by marking _pool_handler as nodebug.
346 - speed up Coro::async considerably.
347 - try some hacks to get netbsd to work "more often" - their broken
348 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
349 - convert Coro to AE 5.0 API.
350
3515.162 Tue Jul 28 04:04:03 CEST 2009
352 - perl 5.8.2 is now minimum requirement.
353 - skip t/19_handle.t on broken windows perls.
354
3555.161 Wed Jul 22 04:47:38 CEST 2009
356 - Coro::AnyEvent::poll could have a different prototype when EV was
357 used as backend (analyzed by Tatsuhiko Miyagawa).
358 - Coro::AnyEvent errornously initialised the event loop when loaded,
359 not on demand.
360 - try to workaround rare */t/01_unblock.t failures.
361
3625.16 Tue Jul 21 01:44:37 CEST 2009
363 - Coro::AnyEvent failed to hook into the event loop
364 when no threads had been readied between detecting
365 the event loop and actually running it.
366 - considerably speed up Coro::Select by taking avdantage
367 of AnyEvent > 4.8 and some other optimisations.
368 - implement paragraph readline mode in Coro::Handle
369 (based on patches by Zsbán Ambrus).
370 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
371 and analyzed by Yasuhiro MATSUMOTO).
372 - clarified libcoro license and copyright.
373 - someone stole my EXTRA_META!!!
374 - implement Coro::Select::patch_pp_sselect and it's brother,
375 for hardcode select overriding.
376
3775.151 Mon Jul 6 05:41:57 CEST 2009
378 - backport to windows process emulation code again (patch by
379 Yasuhiro MATSUMOTO).
380 - slightly update Coro::MakeMaker.
381
3825.15 Tue Jun 30 10:28:06 CEST 2009
383 - deprecate Coro::Socket, document how to get ipv6 support via
384 AnyEvent::Socket instead.
385 - implement signal->wait ($cb) interface, similar to semaphores.
386 - work around SvOK not supporting getmagic, so we have to getmagic
387 to test for undef :/ (reported by Matthias Waldorf).
388 - load Coro::AnyEvent in all modules using AnyEvent.
389 - work around perl corrupting our internal data structures,
390 reported by Tokuhiro Matsuno.
391 - enable per-coroutine real and cpu time gathering
392 (Coro::State::enable_times).
393
3945.14 Wed Jun 24 01:37:48 CEST 2009
395 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
396 as this seems to have been a difficult concept (poll, sleep, idle,
397 idle_upto).
398 - add Coro::AnyEvent::readable/writable functions.
399 - clarify Coro::EV/Event/AnyEvent manpages.
400 - free per-thread global scalars in the thread calling ->cancel, to
401 avoid crashes when $_, $@ etc., are magical but some of those
402 had already been freed.
403 - "unexperimentalise" the callback interface for Coro::Semaphore.
404 - speed up ready queue management/context switching by using a linked
405 list instead of an array (~5-10%).
406 - implement "watch" command in Coro::Debug shells.
407 - for fun, implement time-slicing as an example in the manpage.
408 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
409 Coro::Event, use the normal AnyEvent handling instead of dieing
410 (the same is true for Coro::Handle).
411 - properly document Coro::EV::timed_io_once.
412 - avoid unneccessary ->cancel calls in Coro::Handle.
413 - maybe make it work on mingw32 with win32 backend
414 (based on patch by Yasuhiro Matsumoto).
415
4165.132 Fri May 29 09:00:39 CEST 2009
417 - do not keep a reference to the argument itself in
418 Coro::Semaphore::guard, as it could change later.
419 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
420 should support a prepare callback.
421
4225.131 Mon Mar 16 23:20:37 CET 2009
423 - implement and document Coro->suspend, Coro->resume.
424 - fix Coro::Select implementation to not (often) close
425 the passed file descriptors (testcase provided by pippijn).
426
4275.13 Mon Dec 15 21:51:42 CET 2008
428 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
429 - don't set diehook to C<undef> but instead to NULL, to avoid
430 spurious warnings.
431 - fix a lot of bugs in Coro::SemaphoreSet.
432 - Coro::SemaphoreSet will less often create a semaphore needlessly.
433 - add Coro::SemaphoreSet::count and wait methods.
434 - take advantage of the new Guard module.
435 - deprecate Coro::guard.
436 - try to fix the dreaded 01_unblock tests once more. I hate it when
437 testsuites need more fixing than the code they are supposed to test.
438 - croak in more cases when a required callback isn't resolvable.
439 - fix some minor issues in Coro::State->call/eval.
440 - use current coroutine context instead of a temporary one
441 when temporarily switching to another coroutine.
442 - do not call C-level on_destroy handlers during global destruction,
443 to avoid needless segfaults.
444
4455.12 Sun Dec 7 13:30:38 CET 2008
446 - add default config for MirOS, which seems to be a bug-to-bug
447 compatible fork of openbsd ("world domination by releasing
448 openbsd cvs before the openbsd folks do it" or so :).
449 - free_padlist did destroy the names pad, not good, but didn't
450 seem to bother perl - this could fix issues such as eval ""
451 inside a function called from multiple coroutines.
452 - use a different method to detect destruction time.
453 - be more careful when freeing padlists just before global
454 destruction.
455 - fixed and expanded the call/cc example.
456 - renamed _terminate to _coro_run.
457 - new method Coro::Channel->shutdown.
458 - try pthreads on openbsd <4.4 (broken sigaltstack, will
459 pthreads fare better?).
460 - be less picky about destroying "a" running coroutine.
461
4625.11 Tue Nov 25 21:49:05 CET 2008
463 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
464 working code with failed assertions, introducing more bugs than
465 it fixes, requiring elaborate workarounds :(
466
4675.1 Mon Nov 24 08:54:59 CET 2008
468 - wrote a small introductory tutorial - Coro::Intro.
469 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
470 - Coro::Select did errornously dup the file descriptors
471 and didn't work with all AnyEvent backends.
472 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
473 LWP data transfers.
474 - disassociate c contexts from coro objects - this is agruably more
475 correct, but mostly allows sharing of cctxs between coro and state
476 objects, for added memory savings and speed increases.
477 - bumped $Coro::POOL_RSS up to 32kb by default.
478 - no longer set the optype to OP_CUSTOM, as B::* understandably
479 doesn't like this very much (and we *are* a type of entersub).
480 - implement state cloning, just to prove that call/cc can be done.
481 - automatically load Coro::AnyEvent in Coro::Handle.
482 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
483 do not have this method (and don't need it either).
484 - speed up generic anyevent methods in Coro::Handle by using rouse
485 callbacks.
486 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
487 others. It also makes the debugger happier, as you can trace
488 through the idle threads now.
489 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
490 - eg/event was pretty broken.
491 - better 5.8.6 compatibility.
492
4935.0 Thu Nov 20 10:35:05 CET 2008
494 - NEW ARCHITECTURE: use the latest 4.x version if you experience
495 stability issues.
496 - bump API version to 7 - all dependents must be recompiled.
497 - removed timed_* functions - they were not being used anyways
498 and should be replaced by a more generic mechanism -
499 and were annoying to support anyways :)
500 - removed SemaphoreSet's waiter method - use sem method instead.
501 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
502 - async_pool did free a scalar value twice
503 ("Attempt to unreference...").
504 - fix a longstanding bug where calling terminate on a coro that
505 was waiting for a semaphore that was just becoming available
506 would cause a deadlock (semaphore would get into a state where
507 it was available but waiters were still blocked).
508 - calling throw on a coroutine that is waiting for a semaphore will
509 no longer make it acquire the semaphore (and thus leak a count).
510 - perl's process emulation is now not even theoretically supported
511 anymore.
512 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
513 conversion of callback-style to blocking-style.
514 - new methods $coro->schedule_to and ->cede_to, to specifically
515 schedule or cede to a specific coroutine.
516 - new function Coro::Semaphore::wait.
517 - use named constants in Coro::Channel (Richard Hundt).
518 - directly patch the entersub opcode calling SLF functions (cede,
519 transfer and so on). this does speed up context switching, but
520 more importanly, it frees us from the hardcoded behaviour of
521 entersub, so we might actually be able to return something from
522 those functions and atcually create new ones.
523 - take advantage of __builtin_frame_address on gcc.
524 - expose THX in coroapi (not sure whether this was a wise decision,
525 as "threaded" perls are running at half speed anyways).
526 - implement execute_slf (schedule-like-function) interface that makes
527 it possible to implement schedule-like-functions in XS.
528 - use new SLF interface to massively speed up Coro::EV by roughly a
529 factor of two.
530 - used new SLF interface to massively speed up Coro::Semaphore by a
531 factor of three.
532 - used new SLF interface to speed up Coro::AIO by roughly a factor of
533 four and reduce its memory usage considerably.
534 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
535 for a nice speedup and vastly more correct behaviour. Also implement
536 a new method "sem" to get at the underlying semaphore object.
537 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
538 (in comparison) 20-40% speedup.
539 - used new SLF interface to reimplement Coro::Signal gaining
540 some unknown (because I was too lazy), but certain, speedup, and also
541 making signals reliable for the first time.
542 - used new SLF interface and other optimisations to speed up async_pool
543 by a factor of two. It also doesn't rely on perl's exception mechanism
544 to exit anymore. The overhead for terminating an async_pool, coro over
545 a normal async is now very small.
546 - sped up coroutine creation/destruction by 40%.
547 - forgot to include Coro/libcoro/README in the dist for all these years.
548 - work around a freebsd pthreads bug (manual testcancel is required as
549 pthread_cond_wait isn't a cancellation point on freebsd).
550 - use new rouse functions to speed up and simplify Coro::BDB.
551 - make "prefer perl native functions" work with threaded perls.
552 - condense Coro::Debug ps output, hint at v and w flags.
553 - (libcoro) lots of minor cleanups and portability improvements.
554
5554.914 Wed Nov 19 12:54:18 CET 2008
556 - fix a disastrous bug in the readline optimisation
557 introduced in 4.801.
558
5594.913 Sat Nov 15 07:58:28 CET 2008
560 - async_pool did free a scalar value twice
561 ("Attempt to unreference...").
562
5634.912 Thu Nov 13 18:31:23 CET 2008
564 - minor cleanups.
565 - use much larger stacks on linux and perl < 5.8.8.
566 - Coro::Debug::new_unix_server did not unlink the socket
567 when destroyed.
568
5694.911 Tue Nov 11 04:26:17 CET 2008
570 - "port" to threaded perls.
571
5724.91 Mon Nov 10 05:36:38 CET 2008
573 - the ->throw exception object no longer leaks.
574 - creating a new cctx leaked a scopestack entry (memleak).
575 - new coroutines didn't get created with a zero flags field
576 (unknown impact).
577 - calling ->throw on a not-yet-started coroutine should now work
578 instead of being ignored.
579 - ->throw is now supported on Coro::State objects.
580 - clean up cctx creation code a bit.
581 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
582
5834.9 Sat Nov 8 17:45:27 CET 2008
584 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
585 - (libcoro) no longer leak threads in the experimental pthread backend,
586 also speed it up considerably.
587 - (libcoro) do not rely on makecontext passing void *'s unscathed.
588 - fix compiletime dependencies on libcoro in the Makefile.
589 - cctx_count wasn't always updated properly.
590 - Coro::State::cctx_stacksize wasn't applied correctly.
591 - new function Coro::State::cctx_max_idle.
592 - the default max number of idle C contexts is now 4.
593 - (libcoro) try harder to get _setjmp/_longjmp.
594 - (libcoro) cleanup and extend the libcoro API to officially
595 allow the creation of empty source contexts.
596 - very experimental workaround for the totally broken netbsd platform.
597 - tried to hack around openbsd bugs.
598
5994.804 Wed Nov 5 16:36:00 CET 2008
600 - Coro::Debug::new_unix_server would not create a non-blocking listening
601 socket, sometimes causing freezes.
602 - (libcoro) fix misaligned stack points for setjmp and assembly
603 methods, which can cause crashes on x86/x86_64 with a sufficiently
604 aggressive compiler.
605 - new function: Coro::Debug::new_tcp_server.
606 - move ->throw into the Coro class because it only works on coro objects.
607
6084.803 Mon Nov 3 17:16:12 CET 2008
609 - (libcoro) use a global asm statement to become independent of gcc
610 otpimisations for CORO_ASM (thanks to pippijn for the idea).
611 - try to workaround yet another broken bsd, this time dragonfly.
612
6134.802 Thu Oct 30 10:56:12 CET 2008
614 - support -fno-omit-frame-pointer on x86 with the assembly method.
615 - tune 01_unblock.t tests a bit.
616
6174.801 Wed Oct 22 18:33:37 CEST 2008
618 - improve readline speed for very long "lines".
619 - backport to 5.8.8.
620
6214.8 Thu Oct 2 13:34:40 CEST 2008
622 - new function Coro::AIO::aio_wait.
623 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
624 - greatly speed up and reduce memory usage of Coro::AIO requests.
625 - implement some other µ-optimisations.
626
6274.749 Mon Sep 29 14:40:12 CEST 2008
628 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
629
6304.748 Sat Sep 27 14:03:19 CEST 2008
631 - implement, but do not document, PerlIO::cede(granularity).
632 - Coro::Storable forgot to wrap Storable::pstore.
633 - work around the multitude of leaks and memory corruption
634 bugs in PerlIO::via by using our own C-level perliol. As a side
635 effect, Coro::Storable is now much, much, much faster.
636
6374.747 Tue Sep 23 01:59:41 CEST 2008
638 - fix a per-cv memleak (one empty array was leaked per
639 code reference).
640 - avoid a crash in coro->call|rss when the coroutine was already
641 destroyed (most noticably when using Coro::Debug::ps :)
642 - also protect *Storable::FILE.
643 - push up default storable granularity to 20ms.
644
6454.746 Sun Sep 21 03:22:20 CEST 2008
646 - be more insistent on locking Storable against reentrancy
647 in Coro::Storable.
648 - move swap_def?v and throw to Coro::State, as documented.
649
6504.745 Thu Jul 24 00:14:38 CEST 2008
651 - remove debugging code related to MgPV_nolen_const, also try to
652 make it compile with perl 5.8.6 (yes, apple apparently loves
653 outdated software). Reported by John S.
654
6554.744 Tue Jul 8 22:06:35 CEST 2008
656 - correctly provide default DIE/WARN handlers as documented.
657 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
658 implementations inside perl work fine for us.
659
6604.743 Mon Jun 16 00:21:57 CEST 2008
661 - when using Coro::EV without running EV::loop it could
662 result in busy-waiting for events, this has been fixed.
663 - reduce codesize and improve performance by using EV_DEFAULT_UC.
664
6654.742 Sat May 31 14:10:21 CEST 2008
666 - implement a workaround for (some) perl <5.8.8 versions.
667 - require EV 3.3+.
668
6694.741 Fri May 30 23:33:09 CEST 2008
670 - tell netbsd how utterly broken their imitation of an OS is
671 and refuse to build by default if pthreads are in use.
672 - switch to "s" method on all bsd's by default, as their ucontext
673 stuff seems just too broken.
674 - fix a bug in Coro::Select.
675
6764.74 Thu May 29 20:05:31 CEST 2008
677 - do not test Coro::LWP for lack of dependencies.
678 - do not test Coro::Select for lack of working perls.
679
6804.73 Thu May 29 2008
681 - fix a bug in Coro::EV which would cause it to block despite
682 there being runnable coroutines.
683 - sprinkle "no warnings" freely over everything, also suppress
684 warnings for some other modules.
685 - fix typo in WSAEWOULDBLOCK.
686
6874.72 Sun May 25 05:14:36 CEST 2008
688 - tweak META.yaml a bit, unfortunately, there is no documented way
689 to have optional dependencies with CPAN. doh :(
690 - avoid running some tests on windows because they would fail due to
691 perl bug (broken fork, broken pipes...).
692 - work around perl on windows bugs where perl returns undocumented
693 error codes for sysread, syswrite etc. by taking advantage
694 of AnyEvent's workaround for that problem.
695 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
696 a common perl implementation bug on windows.
697 - use unix domain sockets in testsuite to work around
698 common perl implementation bugs on widows (they are emulated by
699 tcp sockets on windows. ugh.)
700
7014.71 Sat May 24 20:01:27 CEST 2008
702 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
703 - take advantage of async name resolution of AnyEvent::Util.
704 - work around brutal inet_aton override in Coro::LWP.
705 - take advantage of the readyhook in Coro::EV, for smoother
706 scheduling.
707
7084.7 Sun May 11 00:32:19 CEST 2008
709 - completely reworked the Coro manpage.
710 - added Coro::AnyEvent, generic event loop integration.
711 - implement cancel, ready and kill commands in Coro::Debug.
712 - document find_coro in Coro::Debug.
713 - incompatible change: rename has_stack to has_cctx.
714 - Coro::AIO and Coro::BDB no longer force event model detection,
715 use AnyEvent::AIO and AnyEvent::BDB.
716
7174.6 Sat Apr 26 10:05:14 CEST 2008
718 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
719 by the Coro module. It was a mistake to have it in the first place.
720 - (experimental) support for activestate perl 5.10 (method "w").
721 - (experimental) support for strawberry perl (method "a").
722 - coro_sigelem_set did not return a value although it had to,
723 actual impact unknown.
724
7254.51 Mon Apr 14 13:28:27 CEST 2008
726 - make it compile again on 5.8.
727
7284.50 Thu Apr 10 09:43:17 CEST 2008
729 - I did it twice! (see 4.49).
730
7314.49 Sun Apr 6 21:23:31 CEST 2008
732 - grr, instead of compiling the recent changes on 5.10 only they
733 were compiled on 5.8 only.
734
7354.48 Sun Apr 6 20:36:46 CEST 2008
736 - allow coroutine switches during eval's under 5.10.x, as it seems
737 the parser is a per-interpreter option now, so this is safe
738 (this might fix the odd crashing bug).
739 - drop support for 5.9.x versions: they are dead, jim.
740
7414.47 Sun Apr 6 00:37:52 CEST 2008
742 - force cctx allocation on API calls: we know we need to force one
743 and gcc actually manages to confuse our heuristic nowadays,
744 leading to crashes and worse.
745 - document force_cctx.
746
7474.46 Fri Apr 4 22:05:43 CEST 2008
748 - upgrade libcoro, resulting in pthread-backend (which was only created
749 to fulfill the rules of the programming languages shootout).
750
7514.45 Thu Mar 13 11:55:36 CET 2008
752 - fix a file leaking bug in eg/mhyttpd that would allow
753 downloading of any file (reported by oesi).
754 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
755 (also add testcase).
756 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
757 apparently having loads of fun with that).
758 - implement $state->swap_defsv, ->swap_defav and document ->throw.
759
7604.4 Wed Feb 13 16:44:29 CET 2008
761 - only assume .cfi pseudo isns exist on GNU/Linux.
762 - add get_timed method to Coro::Channels.
763 - fixed Coro::Debug manpage.
764 - perl 5.11 compatbility improvement based on patch by
765 Andreas König.
766
7674.37 Sun Jan 20 11:25:23 CET 2008
768 - soften the check for an active parser for perl 5.10 (avoiding
769 "Coro::State::transfer called while parsing" in many cases).
770
7714.36 Sun Jan 13 10:53:56 CET 2008
772 - reset diehook when terminating from an async_pool as to not
773 trigger any __DIE__ handlers.
774
7754.35 Sun Jan 13 04:14:13 CET 2008
9 - "bt" debug command now displays any exceptions 776 - "bt" debug command now displays any exceptions
