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)?

86.09 Sat Oct 6 23:25:02 CEST 2012
9 - Coro::EV I/O watchers were not interruptible by exceptions
10 (Coro::State::throw) (testcase by sten).
11 - ->throw now puts threads into the ready queue, as this seems to
12 be expected by existing code, and code that doesn't cope with spurious
13 wakeups needs fixing anyway.
14 - use fd -1 in mmap.
15 - cast I32 to int in error message printf.
16 - warn about broken so-called "hardened" kernels.
17
186.08 Fri Apr 13 12:05:47 CEST 2012
19 - be more aggressive about exiting like perl does - formerly,
20 exiting from the non-main thread would not execute END blocks.
21
226.07 Fri Nov 11 21:21:48 CET 2011
23 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
24 - update ecb.h.
25
266.06 Mon Aug 8 23:59:48 CEST 2011
27 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
28 backend, which is an order of magnitude slower. unfortunately, cygwins
29 pthread implementation isn't very complete either, so allocate the stack
30 twice just to be sure.
31 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
32 in its ithreaded perl - best recompile cygwin and use the 'w'indows
33 backend for much better performance. also disable ithreads for
34 even better performance...).
35
366.05 Thu Aug 4 21:36:36 CEST 2011
37 - blush, condvar values would not be propagated from send to recv anymore
38 (reported by Chip Salzenberg).
39 - use exponential increase for the readline buffer length in
40 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
41
426.04 Wed Aug 3 17:15:45 CEST 2011
43 - use even more efficient and more compatible condvars for
44 compatibility to AnyEvent 6.x :)
45 - more inconsequential ecb.h updates.
46
476.03 Wed Aug 3 11:41:30 CEST 2011
48 - change how Coro patches AnyEvent condvars for compatibility to
49 AnyEvent 6.x.
50 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
51 hasn't been included.
52
536.02 Wed Jul 13 04:35:19 CEST 2011
54 - "improve portability to Gentoo" - gentoo manages to put perl variables
55 in memory areas that are farther than 2gb apart, which the jit couldn't
56 handle and barfed. now it's just a bit slower on gentoo and similar
57 systems.
58
596.01 Sun Jul 3 12:31:14 CEST 2011
60 - workarounds are good, but the test for whether pthreads are used
61 was not good. thisone should be better.
62 - check differently whether gcc generates cfi instructions itself.
63
646.0 Wed Jun 29 19:43:35 CEST 2011
65 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
66 destroyed and cleaned up automatically (e.g. async { schedule }).
67 - implement a JIT compiler for part of the thread switch code,
68 which gives a 50% speed improvement on threaded perls, and
69 about 4% on non-thraeded perls (so threaded perls now finally
70 reach about half the speed of non-threaded perls).
71 - slightly modernise Coro::Intro, add section about rouse functions.
72 - avoid DEFSV and ERRSV, giving another 10% improvement
73 in thread switching.
74 - Coro::State->is_destroyed is now called is_zombie.
75 - implement a Coro->safe_cancel method that might fail, but
76 cancels in a "safer" way if it succeeds.
77 - add preliminary support for DEBUGGING perls.
78 - get rid of two hash-accesses when initialising a new Coro - this
79 speeds up coro creation by almost a factor of two.
80 - croak when a coro that is being cancelled tries to block
81 (e.g. while executing a guard block), instead of crashing or
82 deadlocking.
83 - use a more robust and also faster method to identify Coro::State
84 objects - speeds up everything a bit.
85 - implement Coro->cancel in XS for a 20% speed improvement, and to
86 be able to implement mutual cancellation.
87 - speed up context switches by a percent or two by more efficiently
88 allocating context stack entries.
89 - implement Coro->join and Coro->on_destroy in XS for a speedup and
90 a reduction in memory use.
91 - cancelling a coro while it itself is cancelling another coro is
92 now supported and working, instead of triggering an assertion.
93 - be a bit more crash-resistant when calling (buggy) on_destroy
94 callbacks (best effort).
95 - move on_destroy into the slf_frame, to allow extension slf
96 functions to have destructors.
97 - get rid if coro refcounting - simply crash in other interpreter
98 threads by nulling the pointers on clone.
99 - simplify warn/die hook handling when loading Coro - the convoluted
100 logic seems to be no longer neccessary.
101 - use libecb instead of our own home-grown gcc hacks.
102 - document alternatives to Coro::LWP. Please use them :)
103 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
104 sigaltstack. Really. wine suffers from it, erlang suffers from it,
105 and it's known since at least 2006.
106
1075.372 Wed Feb 23 06:14:30 CET 2011
108 - apparently mingw doesn't provide a working gettimeofday, try to
109 work around that by relying on Time::HiRes (indirectly brought to
110 my attention by Max Maischein).
111 - fix some portability issues when Time::HiRes was used.
112
1135.371 Mon Feb 21 14:36:08 CET 2011
114 - backport to windows process emulation code again.
115
1165.37 Sat Feb 19 07:49:44 CET 2011
117 - add a big "Coro thread life cycle" section to "man Coro".
118 - try a tentative workaround against the breakage that 5.13 has
119 introduced without depreciation period. sigh.
120 - no longer use Time::HiRes if gettimeofday is available, which
121 saves quite a lot of memory.
122
1235.36 Sun Feb 13 05:33:41 CET 2011
124 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
125 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
126 method call.
127 - undocument Coro::Timer::sleep and obsolete whole module.
128 - optimise Coro::Timer::timeout memory and cpu usage.
129 - slightly updated Coro::Intro for recent changes.
130 - do not initialise PL_dirty anymore.
131
1325.25 Thu Nov 11 01:08:39 CET 2010
133 - try a different approach on netbsd - netbsd 5 finally has marginally
134 working pthreads, but still broken ucontext/sigaltstack.
135 - openbsd 4.8 finally got their act together, Coro works out of the box
136 with asm, setjmp and pthreads (no change, just informational).
137
1385.24 Sat Oct 23 11:27:12 CEST 2010
139 - port to the EV 4.0 API.
140 - work around bugs in mingw32, making strawberry perl work
141 out of the box.
142 - correctly modify Coro::AIO function prototypes
143 so that they reflect the "no optional parameters" rule.
144 - "ported" libcoro to C++.
145
1465.23 Mon May 17 18:50:42 CEST 2010
147 - be more resistant to ordering changes when initialising
148 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
149 Waldorf).
150 - document that perl 5.12 deliberately removed support for cloning.
151
1525.22 Wed Apr 14 03:55:35 CEST 2010
153 - correctly return udnef on errors in Coro::Handle::read/write
154 (testcase by Marc Mims).
155 - convert Coro::Util into a "perl compatibility wrapper" - the functions
156 are less useful now, but are drop-in replacements for existing
157 functions, listing better alternatives in the documentation. This also
158 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
159 with Coro::Util::inet_aton.
160 - do not override $Coro::idle unconditionally in Coro.pm, as other
161 modules could have provided their own idle coro already
162 (for exmaple, Coro::AnyEvent).
163 - fix Coro::Util::gethost* functions.
164 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
165
1665.21 Wed Dec 16 07:19:51 CET 2009
167 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
168 together.
169 - add some examples on how to combine other event loops with Coro in
170 Coro::AnyEvent, and how to run it (and not to block). Seems to be
171 the most common source of confusion.
172 - try to catch people naively blocking in an event callback.
173 - work around the perl filehandle bug issue in conjunction with
174 older common::sense (as indirectly pointed out by ZSystem).
175 - clarify the "not from signal handlers" section.
176
1775.2 Sun Oct 4 14:54:24 CEST 2009
178 - Coro::Storable destroyed the prototypes of the functions it wrapped.
179 - export rouse_cb and rouse_wait by default now.
180 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
181 - new method $state->swap_sv.
182 - added section on "windows process emulation" to the manpage,
183 after a not-so-fruitful (nor-friendly) "discussion" with chip
184 salzenberg (discussion implies arguments, but his only arguments
185 were ad-hominems, one wonders why he started it in the first
186 place). I hope this explains it well enough for him to understand,
187 and maybe well enough for others to understand.
188 - use common::sense everywhere now.
189 - idle callbacks are no longer supported, use idle coros instead.
190 - print a thread listing when a deadlock is detected.
191
1925.17 Sat Aug 22 23:09:31 CEST 2009
193 - work around a bug in the perl debugger causing crashes
194 when running under the debugger by marking _pool_handler as nodebug.
195 - speed up Coro::async considerably.
196 - try some hacks to get netbsd to work "more often" - their broken
197 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
198 - convert Coro to AE 5.0 API.
199
2005.162 Tue Jul 28 04:04:03 CEST 2009
201 - perl 5.8.2 is now minimum requirement.
202 - skip t/19_handle.t on broken windows perls.
203
2045.161 Wed Jul 22 04:47:38 CEST 2009
205 - Coro::AnyEvent::poll could have a different prototype when EV was
206 used as backend (analyzed by Tatsuhiko Miyagawa).
207 - Coro::AnyEvent errornously initialised the event loop when loaded,
208 not on demand.
209 - try to workaround rare */t/01_unblock.t failures.
210
2115.16 Tue Jul 21 01:44:37 CEST 2009
212 - Coro::AnyEvent failed to hook into the event loop
213 when no threads had been readied between detecting
214 the event loop and actually running it.
215 - considerably speed up Coro::Select by taking avdantage
216 of AnyEvent > 4.8 and some other optimisations.
217 - implement paragraph readline mode in Coro::Handle
218 (based on patches by Zsbán Ambrus).
219 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
220 and analyzed by Yasuhiro MATSUMOTO).
221 - clarified libcoro license and copyright.
222 - someone stole my EXTRA_META!!!
223 - implement Coro::Select::patch_pp_sselect and it's brother,
224 for hardcode select overriding.
225
2265.151 Mon Jul 6 05:41:57 CEST 2009
227 - backport to windows process emulation code again (patch by
228 Yasuhiro MATSUMOTO).
229 - slightly update Coro::MakeMaker.
230
2315.15 Tue Jun 30 10:28:06 CEST 2009
232 - deprecate Coro::Socket, document how to get ipv6 support via
233 AnyEvent::Socket instead.
234 - implement signal->wait ($cb) interface, similar to semaphores.
235 - work around SvOK not supporting getmagic, so we have to getmagic
236 to test for undef :/ (reported by Matthias Waldorf).
237 - load Coro::AnyEvent in all modules using AnyEvent.
238 - work around perl corrupting our internal data structures,
239 reported by Tokuhiro Matsuno.
240 - enable per-coroutine real and cpu time gathering
241 (Coro::State::enable_times).
242
2435.14 Wed Jun 24 01:37:48 CEST 2009
244 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
245 as this seems to have been a difficult concept (poll, sleep, idle,
246 idle_upto).
247 - add Coro::AnyEvent::readable/writable functions.
248 - clarify Coro::EV/Event/AnyEvent manpages.
249 - free per-thread global scalars in the thread calling ->cancel, to
250 avoid crashes when $_, $@ etc., are magical but some of those
251 had already been freed.
252 - "unexperimentalise" the callback interface for Coro::Semaphore.
253 - speed up ready queue management/context switching by using a linked
254 list instead of an array (~5-10%).
255 - implement "watch" command in Coro::Debug shells.
256 - for fun, implement time-slicing as an example in the manpage.
257 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
258 Coro::Event, use the normal AnyEvent handling instead of dieing
259 (the same is true for Coro::Handle).
260 - properly document Coro::EV::timed_io_once.
261 - avoid unneccessary ->cancel calls in Coro::Handle.
262 - maybe make it work on mingw32 with win32 backend
263 (based on patch by Yasuhiro Matsumoto).
264
2655.132 Fri May 29 09:00:39 CEST 2009
266 - do not keep a reference to the argument itself in
267 Coro::Semaphore::guard, as it could change later.
268 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
269 should support a prepare callback.
270
2715.131 Mon Mar 16 23:20:37 CET 2009
272 - implement and document Coro->suspend, Coro->resume.
273 - fix Coro::Select implementation to not (often) close
274 the passed file descriptors (testcase provided by pippijn).
275
2765.13 Mon Dec 15 21:51:42 CET 2008
277 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
278 - don't set diehook to C<undef> but instead to NULL, to avoid
279 spurious warnings.
280 - fix a lot of bugs in Coro::SemaphoreSet.
281 - Coro::SemaphoreSet will less often create a semaphore needlessly.
282 - add Coro::SemaphoreSet::count and wait methods.
283 - take advantage of the new Guard module.
284 - deprecate Coro::guard.
285 - try to fix the dreaded 01_unblock tests once more. I hate it when
286 testsuites need more fixing than the code they are supposed to test.
287 - croak in more cases when a required callback isn't resolvable.
288 - fix some minor issues in Coro::State->call/eval.
289 - use current coroutine context instead of a temporary one
290 when temporarily switching to another coroutine.
291 - do not call C-level on_destroy handlers during global destruction,
292 to avoid needless segfaults.
293
2945.12 Sun Dec 7 13:30:38 CET 2008
295 - add default config for MirOS, which seems to be a bug-to-bug
296 compatible fork of openbsd ("world domination by releasing
297 openbsd cvs before the openbsd folks do it" or so :).
298 - free_padlist did destroy the names pad, not good, but didn't
299 seem to bother perl - this could fix issues such as eval ""
300 inside a function called from multiple coroutines.
301 - use a different method to detect destruction time.
302 - be more careful when freeing padlists just before global
303 destruction.
304 - fixed and expanded the call/cc example.
305 - renamed _terminate to _coro_run.
306 - new method Coro::Channel->shutdown.
307 - try pthreads on openbsd <4.4 (broken sigaltstack, will
308 pthreads fare better?).
309 - be less picky about destroying "a" running coroutine.
310
3115.11 Tue Nov 25 21:49:05 CET 2008
312 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
313 working code with failed assertions, introducing more bugs than
314 it fixes, requiring elaborate workarounds :(
315
3165.1 Mon Nov 24 08:54:59 CET 2008
317 - wrote a small introductory tutorial - Coro::Intro.
318 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
319 - Coro::Select did errornously dup the file descriptors
320 and didn't work with all AnyEvent backends.
321 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
322 LWP data transfers.
323 - disassociate c contexts from coro objects - this is agruably more
324 correct, but mostly allows sharing of cctxs between coro and state
325 objects, for added memory savings and speed increases.
326 - bumped $Coro::POOL_RSS up to 32kb by default.
327 - no longer set the optype to OP_CUSTOM, as B::* understandably
328 doesn't like this very much (and we *are* a type of entersub).
329 - implement state cloning, just to prove that call/cc can be done.
330 - automatically load Coro::AnyEvent in Coro::Handle.
331 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
332 do not have this method (and don't need it either).
333 - speed up generic anyevent methods in Coro::Handle by using rouse
334 callbacks.
335 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
336 others. It also makes the debugger happier, as you can trace
337 through the idle threads now.
338 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
339 - eg/event was pretty broken.
340 - better 5.8.6 compatibility.
341
3425.0 Thu Nov 20 10:35:05 CET 2008
343 - NEW ARCHITECTURE: use the latest 4.x version if you experience
344 stability issues.
345 - bump API version to 7 - all dependents must be recompiled.
346 - removed timed_* functions - they were not being used anyways
347 and should be replaced by a more generic mechanism -
348 and were annoying to support anyways :)
349 - removed SemaphoreSet's waiter method - use sem method instead.
350 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
351 - async_pool did free a scalar value twice
352 ("Attempt to unreference...").
353 - fix a longstanding bug where calling terminate on a coro that
354 was waiting for a semaphore that was just becoming available
355 would cause a deadlock (semaphore would get into a state where
356 it was available but waiters were still blocked).
357 - calling throw on a coroutine that is waiting for a semaphore will
358 no longer make it acquire the semaphore (and thus leak a count).
359 - perl's process emulation is now not even theoretically supported
360 anymore.
361 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
362 conversion of callback-style to blocking-style.
363 - new methods $coro->schedule_to and ->cede_to, to specifically
364 schedule or cede to a specific coroutine.
365 - new function Coro::Semaphore::wait.
366 - use named constants in Coro::Channel (Richard Hundt).
367 - directly patch the entersub opcode calling SLF functions (cede,
368 transfer and so on). this does speed up context switching, but
369 more importanly, it frees us from the hardcoded behaviour of
370 entersub, so we might actually be able to return something from
371 those functions and atcually create new ones.
372 - take advantage of __builtin_frame_address on gcc.
373 - expose THX in coroapi (not sure whether this was a wise decision,
374 as "threaded" perls are running at half speed anyways).
375 - implement execute_slf (schedule-like-function) interface that makes
376 it possible to implement schedule-like-functions in XS.
377 - use new SLF interface to massively speed up Coro::EV by roughly a
378 factor of two.
379 - used new SLF interface to massively speed up Coro::Semaphore by a
380 factor of three.
381 - used new SLF interface to speed up Coro::AIO by roughly a factor of
382 four and reduce its memory usage considerably.
383 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
384 for a nice speedup and vastly more correct behaviour. Also implement
385 a new method "sem" to get at the underlying semaphore object.
386 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
387 (in comparison) 20-40% speedup.
388 - used new SLF interface to reimplement Coro::Signal gaining
389 some unknown (because I was too lazy), but certain, speedup, and also
390 making signals reliable for the first time.
391 - used new SLF interface and other optimisations to speed up async_pool
392 by a factor of two. It also doesn't rely on perl's exception mechanism
393 to exit anymore. The overhead for terminating an async_pool, coro over
394 a normal async is now very small.
395 - sped up coroutine creation/destruction by 40%.
396 - forgot to include Coro/libcoro/README in the dist for all these years.
397 - work around a freebsd pthreads bug (manual testcancel is required as
398 pthread_cond_wait isn't a cancellation point on freebsd).
399 - use new rouse functions to speed up and simplify Coro::BDB.
400 - make "prefer perl native functions" work with threaded perls.
401 - condense Coro::Debug ps output, hint at v and w flags.
402 - (libcoro) lots of minor cleanups and portability improvements.
403
4044.914 Wed Nov 19 12:54:18 CET 2008
405 - fix a disastrous bug in the readline optimisation
406 introduced in 4.801.
407
4084.913 Sat Nov 15 07:58:28 CET 2008
409 - async_pool did free a scalar value twice
410 ("Attempt to unreference...").
411
4124.912 Thu Nov 13 18:31:23 CET 2008
413 - minor cleanups.
414 - use much larger stacks on linux and perl < 5.8.8.
415 - Coro::Debug::new_unix_server did not unlink the socket
416 when destroyed.
417
4184.911 Tue Nov 11 04:26:17 CET 2008
419 - "port" to threaded perls.
420
4214.91 Mon Nov 10 05:36:38 CET 2008
422 - the ->throw exception object no longer leaks.
423 - creating a new cctx leaked a scopestack entry (memleak).
424 - new coroutines didn't get created with a zero flags field
425 (unknown impact).
426 - calling ->throw on a not-yet-started coroutine should now work
427 instead of being ignored.
428 - ->throw is now supported on Coro::State objects.
429 - clean up cctx creation code a bit.
430 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
431
4324.9 Sat Nov 8 17:45:27 CET 2008
433 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
434 - (libcoro) no longer leak threads in the experimental pthread backend,
435 also speed it up considerably.
436 - (libcoro) do not rely on makecontext passing void *'s unscathed.
437 - fix compiletime dependencies on libcoro in the Makefile.
438 - cctx_count wasn't always updated properly.
439 - Coro::State::cctx_stacksize wasn't applied correctly.
440 - new function Coro::State::cctx_max_idle.
441 - the default max number of idle C contexts is now 4.
442 - (libcoro) try harder to get _setjmp/_longjmp.
443 - (libcoro) cleanup and extend the libcoro API to officially
444 allow the creation of empty source contexts.
445 - very experimental workaround for the totally broken netbsd platform.
446 - tried to hack around openbsd bugs.
447
4484.804 Wed Nov 5 16:36:00 CET 2008
449 - Coro::Debug::new_unix_server would not create a non-blocking listening
450 socket, sometimes causing freezes.
451 - (libcoro) fix misaligned stack points for setjmp and assembly
452 methods, which can cause crashes on x86/x86_64 with a sufficiently
453 aggressive compiler.
454 - new function: Coro::Debug::new_tcp_server.
455 - move ->throw into the Coro class because it only works on coro objects.
456
4574.803 Mon Nov 3 17:16:12 CET 2008
458 - (libcoro) use a global asm statement to become independent of gcc
459 otpimisations for CORO_ASM (thanks to pippijn for the idea).
460 - try to workaround yet another broken bsd, this time dragonfly.
461
4624.802 Thu Oct 30 10:56:12 CET 2008
463 - support -fno-omit-frame-pointer on x86 with the assembly method.
464 - tune 01_unblock.t tests a bit.
465
4664.801 Wed Oct 22 18:33:37 CEST 2008
467 - improve readline speed for very long "lines".
468 - backport to 5.8.8.
469
4704.8 Thu Oct 2 13:34:40 CEST 2008
471 - new function Coro::AIO::aio_wait.
472 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
473 - greatly speed up and reduce memory usage of Coro::AIO requests.
474 - implement some other µ-optimisations.
475
4764.749 Mon Sep 29 14:40:12 CEST 2008
477 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
478
4794.748 Sat Sep 27 14:03:19 CEST 2008
480 - implement, but do not document, PerlIO::cede(granularity).
481 - Coro::Storable forgot to wrap Storable::pstore.
482 - work around the multitude of leaks and memory corruption
483 bugs in PerlIO::via by using our own C-level perliol. As a side
484 effect, Coro::Storable is now much, much, much faster.
485
4864.747 Tue Sep 23 01:59:41 CEST 2008
487 - fix a per-cv memleak (one empty array was leaked per
488 code reference).
489 - avoid a crash in coro->call|rss when the coroutine was already
490 destroyed (most noticably when using Coro::Debug::ps :)
491 - also protect *Storable::FILE.
492 - push up default storable granularity to 20ms.
493
4944.746 Sun Sep 21 03:22:20 CEST 2008
495 - be more insistent on locking Storable against reentrancy
496 in Coro::Storable.
497 - move swap_def?v and throw to Coro::State, as documented.
498
4994.745 Thu Jul 24 00:14:38 CEST 2008
500 - remove debugging code related to MgPV_nolen_const, also try to
501 make it compile with perl 5.8.6 (yes, apple apparently loves
502 outdated software). Reported by John S.
503
5044.744 Tue Jul 8 22:06:35 CEST 2008
505 - correctly provide default DIE/WARN handlers as documented.
506 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
507 implementations inside perl work fine for us.
508
5094.743 Mon Jun 16 00:21:57 CEST 2008
510 - when using Coro::EV without running EV::loop it could
511 result in busy-waiting for events, this has been fixed.
512 - reduce codesize and improve performance by using EV_DEFAULT_UC.
513
5144.742 Sat May 31 14:10:21 CEST 2008
515 - implement a workaround for (some) perl <5.8.8 versions.
516 - require EV 3.3+.
517
5184.741 Fri May 30 23:33:09 CEST 2008
519 - tell netbsd how utterly broken their imitation of an OS is
520 and refuse to build by default if pthreads are in use.
521 - switch to "s" method on all bsd's by default, as their ucontext
522 stuff seems just too broken.
523 - fix a bug in Coro::Select.
524
5254.74 Thu May 29 20:05:31 CEST 2008
526 - do not test Coro::LWP for lack of dependencies.
527 - do not test Coro::Select for lack of working perls.
528
5294.73 Thu May 29 2008
530 - fix a bug in Coro::EV which would cause it to block despite
531 there being runnable coroutines.
532 - sprinkle "no warnings" freely over everything, also suppress
533 warnings for some other modules.
534 - fix typo in WSAEWOULDBLOCK.
535
5364.72 Sun May 25 05:14:36 CEST 2008
537 - tweak META.yaml a bit, unfortunately, there is no documented way
538 to have optional dependencies with CPAN. doh :(
539 - avoid running some tests on windows because they would fail due to
540 perl bug (broken fork, broken pipes...).
541 - work around perl on windows bugs where perl returns undocumented
542 error codes for sysread, syswrite etc. by taking advantage
543 of AnyEvent's workaround for that problem.
544 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
545 a common perl implementation bug on windows.
546 - use unix domain sockets in testsuite to work around
547 common perl implementation bugs on widows (they are emulated by
548 tcp sockets on windows. ugh.)
549
5504.71 Sat May 24 20:01:27 CEST 2008
551 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
552 - take advantage of async name resolution of AnyEvent::Util.
553 - work around brutal inet_aton override in Coro::LWP.
554 - take advantage of the readyhook in Coro::EV, for smoother
555 scheduling.
556
5574.7 Sun May 11 00:32:19 CEST 2008
558 - completely reworked the Coro manpage.
559 - added Coro::AnyEvent, generic event loop integration.
560 - implement cancel, ready and kill commands in Coro::Debug.
561 - document find_coro in Coro::Debug.
562 - incompatible change: rename has_stack to has_cctx.
563 - Coro::AIO and Coro::BDB no longer force event model detection,
564 use AnyEvent::AIO and AnyEvent::BDB.
565
5664.6 Sat Apr 26 10:05:14 CEST 2008
567 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
568 by the Coro module. It was a mistake to have it in the first place.
569 - (experimental) support for activestate perl 5.10 (method "w").
570 - (experimental) support for strawberry perl (method "a").
571 - coro_sigelem_set did not return a value although it had to,
572 actual impact unknown.
573
5744.51 Mon Apr 14 13:28:27 CEST 2008
575 - make it compile again on 5.8.
576
5774.50 Thu Apr 10 09:43:17 CEST 2008
578 - I did it twice! (see 4.49).
579
5804.49 Sun Apr 6 21:23:31 CEST 2008
581 - grr, instead of compiling the recent changes on 5.10 only they
582 were compiled on 5.8 only.
583
5844.48 Sun Apr 6 20:36:46 CEST 2008
585 - allow coroutine switches during eval's under 5.10.x, as it seems
586 the parser is a per-interpreter option now, so this is safe
587 (this might fix the odd crashing bug).
588 - drop support for 5.9.x versions: they are dead, jim.
589
5904.47 Sun Apr 6 00:37:52 CEST 2008
591 - force cctx allocation on API calls: we know we need to force one
592 and gcc actually manages to confuse our heuristic nowadays,
593 leading to crashes and worse.
594 - document force_cctx.
595
5964.46 Fri Apr 4 22:05:43 CEST 2008
597 - upgrade libcoro, resulting in pthread-backend (which was only created
598 to fulfill the rules of the programming languages shootout).
599
6004.45 Thu Mar 13 11:55:36 CET 2008
601 - fix a file leaking bug in eg/mhyttpd that would allow
602 downloading of any file (reported by oesi).
603 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
604 (also add testcase).
605 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
606 apparently having loads of fun with that).
607 - implement $state->swap_defsv, ->swap_defav and document ->throw.
608
6094.4 Wed Feb 13 16:44:29 CET 2008
610 - only assume .cfi pseudo isns exist on GNU/Linux.
611 - add get_timed method to Coro::Channels.
612 - fixed Coro::Debug manpage.
613 - perl 5.11 compatbility improvement based on patch by
614 Andreas König.
615
6164.37 Sun Jan 20 11:25:23 CET 2008
617 - soften the check for an active parser for perl 5.10 (avoiding
618 "Coro::State::transfer called while parsing" in many cases).
619
6204.36 Sun Jan 13 10:53:56 CET 2008
621 - reset diehook when terminating from an async_pool as to not
622 trigger any __DIE__ handlers.
623
6244.35 Sun Jan 13 04:14:13 CET 2008
625 - "bt" debug command now displays any exceptions
626 from longmess and also skips the innermost
627 stackframes, giving more useufl output.
628 - allow backtraces in coroutines blocked in Coro::EV,
629 at a <1% speed hit.
630 - handle localising of $SIG{__WARN__} and __DIE__
631 properly (with a proper amount of dirty hacking).
632
6334.34 Sat Dec 22 17:49:53 CET 2007
634 - upgrade to EV version 2.0 API.
635
6364.33 Mon Dec 17 08:36:12 CET 2007
637 - make Coro::AIO etc. loadable in the absence of EV.
638
6394.32 Mon Dec 17 07:46:02 CET 2007
640 - majorly improved Coro::Handle's performance with Coro::EV.
641 - implemented the until now mythical Coro::BDB module.
642 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
643
6444.31 Wed Dec 5 12:32:39 CET 2007
645 - remove warn statement form Coro::Util.
646
6474.3 Tue Dec 4 20:33:14 CET 2007
648 - calls to the idle function could cause stack corruption
649 when the stack changed.
650 - do no longer rely on the presence of EV::DNS if EV is used
651 (because it is gone), but instead take avdantage of EV::ADNS
652 if available.
653 - add ($) prototypes to all functions in Coro::Storable.
654 - use a conventional (safer) idle callback in Coro::EV.
655 - do accept quickly in Coro::Debug to avoid endless loops.
656
6574.22 Fri Nov 30 16:04:04 CET 2007
658 - really use optimised versions for Event and EV in Coro::Util
659 and Coro::Handle.
660
6614.21 Sun Nov 25 10:48:59 CET 2007
662 - fix a spurious memory read.
663 - Coro::EV no longer keeps the eventloop "alive".
664
6654.2 Fri Nov 9 20:47:05 CET 2007
666 - enable/disable tracing from a new coroutine, not a pooled one.
667 - fix a memleak in Coro::Event.
668 - removed killall call from fork_eval.
669 - made sure store_fd is already loaded so that fork_eval
670 does not have to parse autoload in each subprocess.
671 - only use assembly method if -O switch is in $Config{optimize}.
672 - add (optional) Coro::EV module, so far the best event loop module
673 directly supported by Coro.
674 - if the event model is EV, use EV::DNS to resolve
675 stuff in Coro::Util.
676 - don't get confused by multiple event notifications in Coro::Handle.
677 - initial support for EV (libevent interface).
678 - require Event and EV using configure_requires, to force their existance.
679
6804.13 Wed Oct 24 07:26:45 CEST 2007
681 - add Coro::Storable::blocking_thaw.
682 - use a vastly more complicated technique to localise
683 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
684 - use a coroutine for the idle callback Coro::Event,
685 instead of running Event in the current coroutine context.
686 This also catches recursive invocations.
687 - actually report fork errors in gethostbyname and inet_aton.
688
6894.11 Thu Oct 11 02:40:24 CEST 2007
690 - port to threaded perls.
691
6924.1 Thu Oct 11 02:38:16 CEST 2007
693 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
694 be local to each coro (see Coro::State).
695 - incompatible change: for very deep reasons, cede and cede_notself
696 cannot return anything, so nothing will be returned.
697 - possibly bring back 5.10 compatibility (untested).
698 - work around stupid (and wrong) warning on 5.10 :(.
699 - overlay the saved state over the context stack. This saves
700 a few hundred bytes per coroutine on average and also
701 speeds up context switching a bit.
702 - further tune default stack sizes.
703 - (more) correctly calculate stack usage in coro_rss.
704 - Coro::Storable::blocking_* did not properly lock
705 resulting in races between coroutines.
706 - added Coro::Storable::guard.
707 - stopping to trace a coroutine could destroy the cctx of
708 an unrelated coroutine.
709 - explain the relationship between Perl and C coroutines in
710 more detail in Coro::State.
711 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
712 causing a fork per resolve. This also affected Coro::Socket.
713 - switch to a separate stack in $coro->call/eval to avoid
714 invalidating pointers.
715
7164.03 Sat Oct 6 21:24:00 CEST 2007
717 - added Coro::throw method.
718 - minor code cleanups.
719
7204.02 Sat Oct 6 02:36:47 CEST 2007
721 - fix a very minor per-coroutine memleak (a single codereference).
722 - fixed a bug where the currently in-use c context would be freed
723 prematurely (can happen only when programs change the stacksize
724 or use tracing).
725 - tracing can no longer keep a coro alive after it terminated.
726 - do static branch prediction in the common path for gcc. gives
727 about 2-5% speed improvement here.
7 728
84.01 Fri Oct 5 22:10:49 CEST 2007 7294.01 Fri Oct 5 22:10:49 CEST 2007
9 - instead of recreating *a* standard output handle we simply 730 - instead of recreating *a* standard output handle we simply
10 use STDOUT, which is faster and hopefully more robust. 731 use STDOUT, which is faster and hopefully more robust.
