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: http://www.microsoft.com/msj/archive/s2ce.aspx
6 but very lacking in others (higher level ipc)).
7 6
84.01 7TODO: tutorial
9 - use a different, less descriptive but hopefully more robust way 8TODO: in_eval, PL_tained
10 to create the stdout glob for a newly created coroutine. 9 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
10 destroyed and cleaned up automatically (e.g. async { schedule }).
11 - implement a JIT compiler for part of the thread switch code,
12 which gives a 50% speed improvement on threaded perls, and
13 about 4% on non-thraeded perls (so threaded perls now finally
14 reach about half the speed of non-threaded perls).
15 - avoid DEFSV and ERRSV, giving another 10% improvement
16 in thread switching.
17 - Coro::State->is_destroyed is now called is_zombie.
18 - implement a Coro->safe_cancel method that might fail, but
19 cancels in a "safer" way if it succeeds.
20 - get rid of two hash-accesses when initialising a new Coro - this
21 speeds up coro creation by almost a factor of two.
22 - croak when a coro that is being cancelled tries to block
23 (e.g. while executing a guard block), instead of crashing or
24 deadlocking.
25 - use a more robust and also faster method to identify Coro::State
26 objects - speeds up everything a bit.
27 - implement Coro->cancel in XS for a 20% speed improvement, and to
28 be able to implement mutual cancellation.
29 - speed up context switches by a percent or two by more efficiently
30 allocating context stack entries.
31 - implement Coro->join and Coro->on_destroy in XS for a speedup and
32 a reduction in memory use.
33 - cancelling a coro while it itself is cancelling another coro is
34 now supported and working, instead of triggering an assertion.
35 - be a bit more crash-resistant when calling (buggy) on_destroy
36 callbacks (best effort).
37 - move on_destroy into the slf_frame, to allow extension slf
38 functions to have destructors.
39 - get rid if coro refcounting - simply crash in other interpreter
40 threads by nulling the pointers on clone.
41 - simplify warn/die hook handling when loading Coro - the convoluted
42 logic seems to be no longer neccessary.
43 - use libecb instead of our own home-grown gcc hacks.
44 - document alternatives to Coro::LWP. Please use them :)
45 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
46 sigaltstack. Really. wine suffers from it, erlang suffers from it,
47 and its' known since at least 2006.
48
495.372 Wed Feb 23 06:14:30 CET 2011
50 - apparently mingw doesn't provide a working gettimeofday, try to
51 work around that by relying on Time::HiRes (indirectly brought to
52 my attention by Max Maischein).
53 - fix some portability issues when Time::HiRes was used.
54
555.371 Mon Feb 21 14:36:08 CET 2011
56 - backport to windows process emulation code again.
57
585.37 Sat Feb 19 07:49:44 CET 2011
59 - add a big "Coro thread life cycle" section to "man Coro".
60 - try a tentative workaround against the breakage that 5.13 has
61 introduced without depreciation period. sigh.
62 - no longer use Time::HiRes if gettimeofday is available, which
63 saves quite a lot of memory.
64
655.36 Sun Feb 13 05:33:41 CET 2011
66 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
67 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
68 method call.
69 - undocument Coro::Timer::sleep and obsolete whole module.
70 - optimise Coro::Timer::timeout memory and cpu usage.
71 - slightly updated Coro::Intro for recent changes.
72 - do not initialise PL_dirty anymore.
73
745.25 Thu Nov 11 01:08:39 CET 2010
75 - try a different approach on netbsd - netbsd 5 finally has marginally
76 working pthreads, but still broken ucontext/sigaltstack.
77 - openbsd 4.8 finally got their act together, Coro works out of the box
78 with asm, setjmp and pthreads (no change, just informational).
79
805.24 Sat Oct 23 11:27:12 CEST 2010
81 - port to the EV 4.0 API.
82 - work around bugs in mingw32, making strawberry perl work
83 out of the box.
84 - correctly modify Coro::AIO function prototypes
85 so that they reflect the "no optional parameters" rule.
86 - "ported" libcoro to C++.
87
885.23 Mon May 17 18:50:42 CEST 2010
89 - be more resistant to ordering changes when initialising
90 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
91 Waldorf).
92 - document that perl 5.12 deliberately removed support for cloning.
93
945.22 Wed Apr 14 03:55:35 CEST 2010
95 - correctly return udnef on errors in Coro::Handle::read/write
96 (testcase by Marc Mims).
97 - convert Coro::Util into a "perl compatibility wrapper" - the functions
98 are less useful now, but are drop-in replacements for existing
99 functions, listing better alternatives in the documentation. This also
100 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
101 with Coro::Util::inet_aton.
102 - do not override $Coro::idle unconditionally in Coro.pm, as other
103 modules could have provided their own idle coro already
104 (for exmaple, Coro::AnyEvent).
105 - fix Coro::Util::gethost* functions.
106 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
107
1085.21 Wed Dec 16 07:19:51 CET 2009
109 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
110 together.
111 - add some examples on how to combine other event loops with Coro in
112 Coro::AnyEvent, and how to run it (and not to block). Seems to be
113 the most common source of confusion.
114 - try to catch people naively blocking in an event callback.
115 - work around the perl filehandle bug issue in conjunction with
116 older common::sense (as indirectly pointed out by ZSystem).
117 - clarify the "not from signal handlers" section.
118
1195.2 Sun Oct 4 14:54:24 CEST 2009
120 - Coro::Storable destroyed the prototypes of the functions it wrapped.
121 - export rouse_cb and rouse_wait by default now.
122 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
123 - new method $state->swap_sv.
124 - added section on "windows process emulation" to the manpage,
125 after a not-so-fruitful (nor-friendly) "discussion" with chip
126 salzenberg (discussion implies arguments, but his only arguments
127 were ad-hominems, one wonders why he started it in the first
128 place). I hope this explains it well enough for him to understand,
129 and maybe well enough for others to understand.
130 - use common::sense everywhere now.
131 - idle callbacks are no longer supported, use idle coros instead.
132 - print a thread listing when a deadlock is detected.
133
1345.17 Sat Aug 22 23:09:31 CEST 2009
135 - work around a bug in the perl debugger causing crashes
136 when running under the debugger by marking _pool_handler as nodebug.
137 - speed up Coro::async considerably.
138 - try some hacks to get netbsd to work "more often" - their broken
139 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
140 - convert Coro to AE 5.0 API.
141
1425.162 Tue Jul 28 04:04:03 CEST 2009
143 - perl 5.8.2 is now minimum requirement.
144 - skip t/19_handle.t on broken windows perls.
145
1465.161 Wed Jul 22 04:47:38 CEST 2009
147 - Coro::AnyEvent::poll could have a different prototype when EV was
148 used as backend (analyzed by Tatsuhiko Miyagawa).
149 - Coro::AnyEvent errornously initialised the event loop when loaded,
150 not on demand.
151 - try to workaround rare */t/01_unblock.t failures.
152
1535.16 Tue Jul 21 01:44:37 CEST 2009
154 - Coro::AnyEvent failed to hook into the event loop
155 when no threads had been readied between detecting
156 the event loop and actually running it.
157 - considerably speed up Coro::Select by taking avdantage
158 of AnyEvent > 4.8 and some other optimisations.
159 - implement paragraph readline mode in Coro::Handle
160 (based on patches by Zsbán Ambrus).
161 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
162 and analyzed by Yasuhiro MATSUMOTO).
163 - clarified libcoro license and copyright.
164 - someone stole my EXTRA_META!!!
165 - implement Coro::Select::patch_pp_sselect and it's brother,
166 for hardcode select overriding.
167
1685.151 Mon Jul 6 05:41:57 CEST 2009
169 - backport to windows process emulation code again (patch by
170 Yasuhiro MATSUMOTO).
171 - slightly update Coro::MakeMaker.
172
1735.15 Tue Jun 30 10:28:06 CEST 2009
174 - deprecate Coro::Socket, document how to get ipv6 support via
175 AnyEvent::Socket instead.
176 - implement signal->wait ($cb) interface, similar to semaphores.
177 - work around SvOK not supporting getmagic, so we have to getmagic
178 to test for undef :/ (reported by Matthias Waldorf).
179 - load Coro::AnyEvent in all modules using AnyEvent.
180 - work around perl corrupting our internal data structures,
181 reported by Tokuhiro Matsuno.
182 - enable per-coroutine real and cpu time gathering
183 (Coro::State::enable_times).
184
1855.14 Wed Jun 24 01:37:48 CEST 2009
186 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
187 as this seems to have been a difficult concept (poll, sleep, idle,
188 idle_upto).
189 - add Coro::AnyEvent::readable/writable functions.
190 - clarify Coro::EV/Event/AnyEvent manpages.
191 - free per-thread global scalars in the thread calling ->cancel, to
192 avoid crashes when $_, $@ etc., are magical but some of those
193 had already been freed.
194 - "unexperimentalise" the callback interface for Coro::Semaphore.
195 - speed up ready queue management/context switching by using a linked
196 list instead of an array (~5-10%).
197 - implement "watch" command in Coro::Debug shells.
198 - for fun, implement time-slicing as an example in the manpage.
199 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
200 Coro::Event, use the normal AnyEvent handling instead of dieing
201 (the same is true for Coro::Handle).
202 - properly document Coro::EV::timed_io_once.
203 - avoid unneccessary ->cancel calls in Coro::Handle.
204 - maybe make it work on mingw32 with win32 backend
205 (based on patch by Yasuhiro Matsumoto).
206
2075.132 Fri May 29 09:00:39 CEST 2009
208 - do not keep a reference to the argument itself in
209 Coro::Semaphore::guard, as it could change later.
210 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
211 should support a prepare callback.
212
2135.131 Mon Mar 16 23:20:37 CET 2009
214 - implement and document Coro->suspend, Coro->resume.
215 - fix Coro::Select implementation to not (often) close
216 the passed file descriptors (testcase provided by pippijn).
217
2185.13 Mon Dec 15 21:51:42 CET 2008
219 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
220 - don't set diehook to C<undef> but instead to NULL, to avoid
221 spurious warnings.
222 - fix a lot of bugs in Coro::SemaphoreSet.
223 - Coro::SemaphoreSet will less often create a semaphore needlessly.
224 - add Coro::SemaphoreSet::count and wait methods.
225 - take advantage of the new Guard module.
226 - deprecate Coro::guard.
227 - try to fix the dreaded 01_unblock tests once more. I hate it when
228 testsuites need more fixing than the code they are supposed to test.
229 - croak in more cases when a required callback isn't resolvable.
230 - fix some minor issues in Coro::State->call/eval.
231 - use current coroutine context instead of a temporary one
232 when temporarily switching to another coroutine.
233 - do not call C-level on_destroy handlers during global destruction,
234 to avoid needless segfaults.
235
2365.12 Sun Dec 7 13:30:38 CET 2008
237 - add default config for MirOS, which seems to be a bug-to-bug
238 compatible fork of openbsd ("world domination by releasing
239 openbsd cvs before the openbsd folks do it" or so :).
240 - free_padlist did destroy the names pad, not good, but didn't
241 seem to bother perl - this could fix issues such as eval ""
242 inside a function called from multiple coroutines.
243 - use a different method to detect destruction time.
244 - be more careful when freeing padlists just before global
245 destruction.
246 - fixed and expanded the call/cc example.
247 - renamed _terminate to _coro_run.
248 - new method Coro::Channel->shutdown.
249 - try pthreads on openbsd <4.4 (broken sigaltstack, will
250 pthreads fare better?).
251 - be less picky about destroying "a" running coroutine.
252
2535.11 Tue Nov 25 21:49:05 CET 2008
254 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
255 working code with failed assertions, introducing more bugs than
256 it fixes, requiring elaborate workarounds :(
257
2585.1 Mon Nov 24 08:54:59 CET 2008
259 - wrote a small introductory tutorial - Coro::Intro.
260 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
261 - Coro::Select did errornously dup the file descriptors
262 and didn't work with all AnyEvent backends.
263 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
264 LWP data transfers.
265 - disassociate c contexts from coro objects - this is agruably more
266 correct, but mostly allows sharing of cctxs between coro and state
267 objects, for added memory savings and speed increases.
268 - bumped $Coro::POOL_RSS up to 32kb by default.
269 - no longer set the optype to OP_CUSTOM, as B::* understandably
270 doesn't like this very much (and we *are* a type of entersub).
271 - implement state cloning, just to prove that call/cc can be done.
272 - automatically load Coro::AnyEvent in Coro::Handle.
273 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
274 do not have this method (and don't need it either).
275 - speed up generic anyevent methods in Coro::Handle by using rouse
276 callbacks.
277 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
278 others. It also makes the debugger happier, as you can trace
279 through the idle threads now.
280 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
281 - eg/event was pretty broken.
282 - better 5.8.6 compatibility.
283
2845.0 Thu Nov 20 10:35:05 CET 2008
285 - NEW ARCHITECTURE: use the latest 4.x version if you experience
286 stability issues.
287 - bump API version to 7 - all dependents must be recompiled.
288 - removed timed_* functions - they were not being used anyways
289 and should be replaced by a more generic mechanism -
290 and were annoying to support anyways :)
291 - removed SemaphoreSet's waiter method - use sem method instead.
292 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
293 - async_pool did free a scalar value twice
294 ("Attempt to unreference...").
295 - fix a longstanding bug where calling terminate on a coro that
296 was waiting for a semaphore that was just becoming available
297 would cause a deadlock (semaphore would get into a state where
298 it was available but waiters were still blocked).
299 - calling throw on a coroutine that is waiting for a semaphore will
300 no longer make it acquire the semaphore (and thus leak a count).
301 - perl's process emulation is now not even theoretically supported
302 anymore.
303 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
304 conversion of callback-style to blocking-style.
305 - new methods $coro->schedule_to and ->cede_to, to specifically
306 schedule or cede to a specific coroutine.
307 - new function Coro::Semaphore::wait.
308 - use named constants in Coro::Channel (Richard Hundt).
309 - directly patch the entersub opcode calling SLF functions (cede,
310 transfer and so on). this does speed up context switching, but
311 more importanly, it frees us from the hardcoded behaviour of
312 entersub, so we might actually be able to return something from
313 those functions and atcually create new ones.
314 - take advantage of __builtin_frame_address on gcc.
315 - expose THX in coroapi (not sure whether this was a wise decision,
316 as "threaded" perls are running at half speed anyways).
317 - implement execute_slf (schedule-like-function) interface that makes
318 it possible to implement schedule-like-functions in XS.
319 - use new SLF interface to massively speed up Coro::EV by roughly a
320 factor of two.
321 - used new SLF interface to massively speed up Coro::Semaphore by a
322 factor of three.
323 - used new SLF interface to speed up Coro::AIO by roughly a factor of
324 four and reduce its memory usage considerably.
325 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
326 for a nice speedup and vastly more correct behaviour. Also implement
327 a new method "sem" to get at the underlying semaphore object.
328 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
329 (in comparison) 20-40% speedup.
330 - used new SLF interface to reimplement Coro::Signal gaining
331 some unknown (because I was too lazy), but certain, speedup, and also
332 making signals reliable for the first time.
333 - used new SLF interface and other optimisations to speed up async_pool
334 by a factor of two. It also doesn't rely on perl's exception mechanism
335 to exit anymore. The overhead for terminating an async_pool, coro over
336 a normal async is now very small.
337 - sped up coroutine creation/destruction by 40%.
338 - forgot to include Coro/libcoro/README in the dist for all these years.
339 - work around a freebsd pthreads bug (manual testcancel is required as
340 pthread_cond_wait isn't a cancellation point on freebsd).
341 - use new rouse functions to speed up and simplify Coro::BDB.
342 - make "prefer perl native functions" work with threaded perls.
343 - condense Coro::Debug ps output, hint at v and w flags.
344 - (libcoro) lots of minor cleanups and portability improvements.
345
3464.914 Wed Nov 19 12:54:18 CET 2008
347 - fix a disastrous bug in the readline optimisation
348 introduced in 4.801.
349
3504.913 Sat Nov 15 07:58:28 CET 2008
351 - async_pool did free a scalar value twice
352 ("Attempt to unreference...").
353
3544.912 Thu Nov 13 18:31:23 CET 2008
355 - minor cleanups.
356 - use much larger stacks on linux and perl < 5.8.8.
357 - Coro::Debug::new_unix_server did not unlink the socket
358 when destroyed.
359
3604.911 Tue Nov 11 04:26:17 CET 2008
361 - "port" to threaded perls.
362
3634.91 Mon Nov 10 05:36:38 CET 2008
364 - the ->throw exception object no longer leaks.
365 - creating a new cctx leaked a scopestack entry (memleak).
366 - new coroutines didn't get created with a zero flags field
367 (unknown impact).
368 - calling ->throw on a not-yet-started coroutine should now work
369 instead of being ignored.
370 - ->throw is now supported on Coro::State objects.
371 - clean up cctx creation code a bit.
372 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
373
3744.9 Sat Nov 8 17:45:27 CET 2008
375 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
376 - (libcoro) no longer leak threads in the experimental pthread backend,
377 also speed it up considerably.
378 - (libcoro) do not rely on makecontext passing void *'s unscathed.
379 - fix compiletime dependencies on libcoro in the Makefile.
380 - cctx_count wasn't always updated properly.
381 - Coro::State::cctx_stacksize wasn't applied correctly.
382 - new function Coro::State::cctx_max_idle.
383 - the default max number of idle C contexts is now 4.
384 - (libcoro) try harder to get _setjmp/_longjmp.
385 - (libcoro) cleanup and extend the libcoro API to officially
386 allow the creation of empty source contexts.
387 - very experimental workaround for the totally broken netbsd platform.
388 - tried to hack around openbsd bugs.
389
3904.804 Wed Nov 5 16:36:00 CET 2008
391 - Coro::Debug::new_unix_server would not create a non-blocking listening
392 socket, sometimes causing freezes.
393 - (libcoro) fix misaligned stack points for setjmp and assembly
394 methods, which can cause crashes on x86/x86_64 with a sufficiently
395 aggressive compiler.
396 - new function: Coro::Debug::new_tcp_server.
397 - move ->throw into the Coro class because it only works on coro objects.
398
3994.803 Mon Nov 3 17:16:12 CET 2008
400 - (libcoro) use a global asm statement to become independent of gcc
401 otpimisations for CORO_ASM (thanks to pippijn for the idea).
402 - try to workaround yet another broken bsd, this time dragonfly.
403
4044.802 Thu Oct 30 10:56:12 CET 2008
405 - support -fno-omit-frame-pointer on x86 with the assembly method.
406 - tune 01_unblock.t tests a bit.
407
4084.801 Wed Oct 22 18:33:37 CEST 2008
409 - improve readline speed for very long "lines".
410 - backport to 5.8.8.
411
4124.8 Thu Oct 2 13:34:40 CEST 2008
413 - new function Coro::AIO::aio_wait.
414 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
415 - greatly speed up and reduce memory usage of Coro::AIO requests.
416 - implement some other µ-optimisations.
417
4184.749 Mon Sep 29 14:40:12 CEST 2008
419 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
420
4214.748 Sat Sep 27 14:03:19 CEST 2008
422 - implement, but do not document, PerlIO::cede(granularity).
423 - Coro::Storable forgot to wrap Storable::pstore.
424 - work around the multitude of leaks and memory corruption
425 bugs in PerlIO::via by using our own C-level perliol. As a side
426 effect, Coro::Storable is now much, much, much faster.
427
4284.747 Tue Sep 23 01:59:41 CEST 2008
429 - fix a per-cv memleak (one empty array was leaked per
430 code reference).
431 - avoid a crash in coro->call|rss when the coroutine was already
432 destroyed (most noticably when using Coro::Debug::ps :)
433 - also protect *Storable::FILE.
434 - push up default storable granularity to 20ms.
435
4364.746 Sun Sep 21 03:22:20 CEST 2008
437 - be more insistent on locking Storable against reentrancy
438 in Coro::Storable.
439 - move swap_def?v and throw to Coro::State, as documented.

4414.745 Thu Jul 24 00:14:38 CEST 2008
442 - remove debugging code related to MgPV_nolen_const, also try to
443 make it compile with perl 5.8.6 (yes, apple apparently loves
444 outdated software). Reported by John S.
445
4464.744 Tue Jul 8 22:06:35 CEST 2008
447 - correctly provide default DIE/WARN handlers as documented.
448 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
449 implementations inside perl work fine for us.
450
4514.743 Mon Jun 16 00:21:57 CEST 2008
452 - when using Coro::EV without running EV::loop it could
453 result in busy-waiting for events, this has been fixed.
454 - reduce codesize and improve performance by using EV_DEFAULT_UC.
455
4564.742 Sat May 31 14:10:21 CEST 2008
457 - implement a workaround for (some) perl <5.8.8 versions.
458 - require EV 3.3+.
459
4604.741 Fri May 30 23:33:09 CEST 2008
461 - tell netbsd how utterly broken their imitation of an OS is
462 and refuse to build by default if pthreads are in use.
463 - switch to "s" method on all bsd's by default, as their ucontext
464 stuff seems just too broken.
465 - fix a bug in Coro::Select.
466
4674.74 Thu May 29 20:05:31 CEST 2008
468 - do not test Coro::LWP for lack of dependencies.
469 - do not test Coro::Select for lack of working perls.
470
4714.73 Thu May 29 2008
472 - fix a bug in Coro::EV which would cause it to block despite
473 there being runnable coroutines.
474 - sprinkle "no warnings" freely over everything, also suppress
475 warnings for some other modules.
476 - fix typo in WSAEWOULDBLOCK.
477
4784.72 Sun May 25 05:14:36 CEST 2008
479 - tweak META.yaml a bit, unfortunately, there is no documented way
480 to have optional dependencies with CPAN. doh :(
481 - avoid running some tests on windows because they would fail due to
482 perl bug (broken fork, broken pipes...).
483 - work around perl on windows bugs where perl returns undocumented
484 error codes for sysread, syswrite etc. by taking advantage
485 of AnyEvent's workaround for that problem.
486 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
487 a common perl implementation bug on windows.
488 - use unix domain sockets in testsuite to work around
489 common perl implementation bugs on widows (they are emulated by
490 tcp sockets on windows. ugh.)
491
4924.71 Sat May 24 20:01:27 CEST 2008
493 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
494 - take advantage of async name resolution of AnyEvent::Util.
495 - work around brutal inet_aton override in Coro::LWP.
496 - take advantage of the readyhook in Coro::EV, for smoother
497 scheduling.
498
4994.7 Sun May 11 00:32:19 CEST 2008
500 - completely reworked the Coro manpage.
501 - added Coro::AnyEvent, generic event loop integration.
502 - implement cancel, ready and kill commands in Coro::Debug.
503 - document find_coro in Coro::Debug.
504 - incompatible change: rename has_stack to has_cctx.
505 - Coro::AIO and Coro::BDB no longer force event model detection,
506 use AnyEvent::AIO and AnyEvent::BDB.
507
5084.6 Sat Apr 26 10:05:14 CEST 2008
509 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
510 by the Coro module. It was a mistake to have it in the first place.
511 - (experimental) support for activestate perl 5.10 (method "w").
512 - (experimental) support for strawberry perl (method "a").
513 - coro_sigelem_set did not return a value although it had to,
514 actual impact unknown.
515
5164.51 Mon Apr 14 13:28:27 CEST 2008
517 - make it compile again on 5.8.
518
5194.50 Thu Apr 10 09:43:17 CEST 2008
520 - I did it twice! (see 4.49).
521
5224.49 Sun Apr 6 21:23:31 CEST 2008
523 - grr, instead of compiling the recent changes on 5.10 only they
524 were compiled on 5.8 only.
525
5264.48 Sun Apr 6 20:36:46 CEST 2008
527 - allow coroutine switches during eval's under 5.10.x, as it seems
528 the parser is a per-interpreter option now, so this is safe
529 (this might fix the odd crashing bug).
530 - drop support for 5.9.x versions: they are dead, jim.
531
5324.47 Sun Apr 6 00:37:52 CEST 2008
533 - force cctx allocation on API calls: we know we need to force one
534 and gcc actually manages to confuse our heuristic nowadays,
535 leading to crashes and worse.
536 - document force_cctx.
537
5384.46 Fri Apr 4 22:05:43 CEST 2008
539 - upgrade libcoro, resulting in pthread-backend (which was only created
540 to fulfill the rules of the programming languages shootout).
541
5424.45 Thu Mar 13 11:55:36 CET 2008
543 - fix a file leaking bug in eg/mhyttpd that would allow
544 downloading of any file (reported by oesi).
545 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
546 (also add testcase).
547 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
548 apparently having loads of fun with that).
549 - implement $state->swap_defsv, ->swap_defav and document ->throw.
550
5514.4 Wed Feb 13 16:44:29 CET 2008
552 - only assume .cfi pseudo isns exist on GNU/Linux.
553 - add get_timed method to Coro::Channels.
554 - fixed Coro::Debug manpage.
555 - perl 5.11 compatbility improvement based on patch by
556 Andreas König.
557
5584.37 Sun Jan 20 11:25:23 CET 2008
559 - soften the check for an active parser for perl 5.10 (avoiding
560 "Coro::State::transfer called while parsing" in many cases).
561
5624.36 Sun Jan 13 10:53:56 CET 2008
563 - reset diehook when terminating from an async_pool as to not
564 trigger any __DIE__ handlers.
565
5664.35 Sun Jan 13 04:14:13 CET 2008
567 - "bt" debug command now displays any exceptions
568 from longmess and also skips the innermost
569 stackframes, giving more useufl output.
570 - allow backtraces in coroutines blocked in Coro::EV,
571 at a <1% speed hit.
572 - handle localising of $SIG{__WARN__} and __DIE__
573 properly (with a proper amount of dirty hacking).
574
5754.34 Sat Dec 22 17:49:53 CET 2007
576 - upgrade to EV version 2.0 API.
577
5784.33 Mon Dec 17 08:36:12 CET 2007
579 - make Coro::AIO etc. loadable in the absence of EV.
580
5814.32 Mon Dec 17 07:46:02 CET 2007
582 - majorly improved Coro::Handle's performance with Coro::EV.
583 - implemented the until now mythical Coro::BDB module.
584 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
585
5864.31 Wed Dec 5 12:32:39 CET 2007
587 - remove warn statement form Coro::Util.
588
5894.3 Tue Dec 4 20:33:14 CET 2007
590 - calls to the idle function could cause stack corruption
591 when the stack changed.
592 - do no longer rely on the presence of EV::DNS if EV is used
593 (because it is gone), but instead take avdantage of EV::ADNS
594 if available.
595 - add ($) prototypes to all functions in Coro::Storable.
596 - use a conventional (safer) idle callback in Coro::EV.
597 - do accept quickly in Coro::Debug to avoid endless loops.
598
5994.22 Fri Nov 30 16:04:04 CET 2007
600 - really use optimised versions for Event and EV in Coro::Util
601 and Coro::Handle.
602
6034.21 Sun Nov 25 10:48:59 CET 2007
604 - fix a spurious memory read.
605 - Coro::EV no longer keeps the eventloop "alive".
606
6074.2 Fri Nov 9 20:47:05 CET 2007
608 - enable/disable tracing from a new coroutine, not a pooled one.
609 - fix a memleak in Coro::Event.
610 - removed killall call from fork_eval.
611 - made sure store_fd is already loaded so that fork_eval
612 does not have to parse autoload in each subprocess.
613 - only use assembly method if -O switch is in $Config{optimize}.
614 - add (optional) Coro::EV module, so far the best event loop module
615 directly supported by Coro.
616 - if the event model is EV, use EV::DNS to resolve
617 stuff in Coro::Util.
618 - don't get confused by multiple event notifications in Coro::Handle.
619 - initial support for EV (libevent interface).
620 - require Event and EV using configure_requires, to force their existance.
621
6224.13 Wed Oct 24 07:26:45 CEST 2007
623 - add Coro::Storable::blocking_thaw.
624 - use a vastly more complicated technique to localise
625 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
626 - use a coroutine for the idle callback Coro::Event,
627 instead of running Event in the current coroutine context.
628 This also catches recursive invocations.
629 - actually report fork errors in gethostbyname and inet_aton.
630
6314.11 Thu Oct 11 02:40:24 CEST 2007
632 - port to threaded perls.
633
6344.1 Thu Oct 11 02:38:16 CEST 2007
635 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
636 be local to each coro (see Coro::State).
637 - incompatible change: for very deep reasons, cede and cede_notself
638 cannot return anything, so nothing will be returned.
639 - possibly bring back 5.10 compatibility (untested).
640 - work around stupid (and wrong) warning on 5.10 :(.
641 - overlay the saved state over the context stack. This saves
642 a few hundred bytes per coroutine on average and also
643 speeds up context switching a bit.
644 - further tune default stack sizes.
645 - (more) correctly calculate stack usage in coro_rss.
646 - Coro::Storable::blocking_* did not properly lock
647 resulting in races between coroutines.
648 - added Coro::Storable::guard.
649 - stopping to trace a coroutine could destroy the cctx of
650 an unrelated coroutine.
651 - explain the relationship between Perl and C coroutines in
652 more detail in Coro::State.
653 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
654 causing a fork per resolve. This also affected Coro::Socket.
655 - switch to a separate stack in $coro->call/eval to avoid
656 invalidating pointers.
657
6584.03 Sat Oct 6 21:24:00 CEST 2007
659 - added Coro::throw method.
660 - minor code cleanups.
661
6624.02 Sat Oct 6 02:36:47 CEST 2007
663 - fix a very minor per-coroutine memleak (a single codereference).
664 - fixed a bug where the currently in-use c context would be freed
665 prematurely (can happen only when programs change the stacksize
666 or use tracing).
667 - tracing can no longer keep a coro alive after it terminated.
668 - do static branch prediction in the common path for gcc. gives
669 about 2-5% speed improvement here.
670
6714.01 Fri Oct 5 22:10:49 CEST 2007
672 - instead of recreating *a* standard output handle we simply
673 use STDOUT, which is faster and hopefully more robust.
11 674
124.0 Fri Oct 5 12:56:00 CEST 2007 6754.0 Fri Oct 5 12:56:00 CEST 2007
13 - incompatibly changed Coro::Storable::freeze. 676 - incompatibly changed Coro::Storable::freeze.
14 - major new feature: added Coro::Debug, for interactive coroutine 677 - major new feature: added Coro::Debug, for interactive coroutine
15 debugging, tracing and much more. 678 debugging, tracing and much more.
