2 2
3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: destroy gets only called on cancel: fix(?) 4TODO: unready_all
5TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO. 5TODO: myhttpd header parsing
6TODO: maybe implement a default message channel, very much like Erlang 6TODO: channel->maxsize(newsize)?
7 (which is cool in a lot of important aspects (failures!),
8 but very lacking in others).
9 7
103.7 8 - convert Coro::Util into a "perl compatibility wrapper" - the functions
9 are less useful now, but are drop-in replacements for existing
10 functions, listing better alternatives in the documentation. This also
11 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
12 with Coro::Util::inet_aton.
13 - do not override $Coro::idle unconditionally in Coro.pm, as other
14 modules could have provided their own idle coro already
15 (for exmaple, Coro::AnyEvent).
16 - fix Coro::Util::gethost* functions.
17
185.21 Wed Dec 16 07:19:51 CET 2009
19 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
20 together.
21 - add some examples on how to combine other event loops with Coro in
22 Coro::AnyEvent, and how to run it (and not to block). Seems to be
23 the most common source of confusion.
24 - try to catch people naively blocking in an event callback.
25 - work around the perl filehandle bug issue in conjunction with
26 older common::sense (as indirectly pointed out by ZSystem).
27 - clarify the "not from signal handlers" section.
28
295.2 Sun Oct 4 14:54:24 CEST 2009
30 - Coro::Storable destroyed the prototypes of the functions it wrapped.
31 - export rouse_cb and rouse_wait by default now.
32 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
33 - new method $state->swap_sv.
34 - added section on "windows process emulation" to the manpage,
35 after a not-so-fruitful (nor-friendly) "discussion" with chip
36 salzenberg (discussion implies arguments, but his only arguments
37 were ad-hominems, one wonders why he started it in the first
38 place). I hope this explains it well enough for him to understand,
39 and maybe well enough for others to understand.
40 - use common::sense everywhere now.
41 - idle callbacks are no longer supported, use idle coros instead.
42 - print a thread listing when a deadlock is detected.
43
445.17 Sat Aug 22 23:09:31 CEST 2009
45 - work around a bug in the perl debugger causing crashes
46 when running under the debugger by marking _pool_handler as nodebug.
47 - speed up Coro::async considerably.
48 - try some hacks to get netbsd to work "more often" - their broken
49 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
50 - convert Coro to AE 5.0 API.
51
525.162 Tue Jul 28 04:04:03 CEST 2009
53 - perl 5.8.2 is now minimum requirement.
54 - skip t/19_handle.t on broken windows perls.
55
565.161 Wed Jul 22 04:47:38 CEST 2009
57 - Coro::AnyEvent::poll could have a different prototype when EV was
58 used as backend (analyzed by Tatsuhiko Miyagawa).
59 - Coro::AnyEvent errornously initialised the event loop when loaded,
60 not on demand.
61 - try to workaround rare */t/01_unblock.t failures.
62
635.16 Tue Jul 21 01:44:37 CEST 2009
64 - Coro::AnyEvent failed to hook into the event loop
65 when no threads had been readied between detecting
66 the event loop and actually running it.
67 - considerably speed up Coro::Select by taking avdantage
68 of AnyEvent > 4.8 and some other optimisations.
69 - implement paragraph readline mode in Coro::Handle
70 (based on patches by Zsbán Ambrus).
71 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
72 and analyzed by Yasuhiro MATSUMOTO).
73 - clarified libcoro license and copyright.
74 - someone stole my EXTRA_META!!!
75 - implement Coro::Select::patch_pp_sselect and it's brother,
76 for hardcode select overriding.
77
785.151 Mon Jul 6 05:41:57 CEST 2009
79 - backport to windows process emulation code again (patch by
80 Yasuhiro MATSUMOTO).
81 - slightly update Coro::MakeMaker.
82
835.15 Tue Jun 30 10:28:06 CEST 2009
84 - deprecate Coro::Socket, document how to get ipv6 support via
85 AnyEvent::Socket instead.
86 - implement signal->wait ($cb) interface, similar to semaphores.
87 - work around SvOK not supporting getmagic, so we have to getmagic
88 to test for undef :/ (reported by Matthias Waldorf).
89 - load Coro::AnyEvent in all modules using AnyEvent.
90 - work around perl corrupting our internal data structures,
91 reported by Tokuhiro Matsuno.
92 - enable per-coroutine real and cpu time gathering
93 (Coro::State::enable_times).
94
955.14 Wed Jun 24 01:37:48 CEST 2009
96 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
97 as this seems to have been a difficult concept (poll, sleep, idle,
98 idle_upto).
99 - add Coro::AnyEvent::readable/writable functions.
100 - clarify Coro::EV/Event/AnyEvent manpages.
101 - free per-thread global scalars in the thread calling ->cancel, to
102 avoid crashes when $_, $@ etc., are magical but some of those
103 had already been freed.
104 - "unexperimentalise" the callback interface for Coro::Semaphore.
105 - speed up ready queue management/context switching by using a linked
106 list instead of an array (~5-10%).
107 - implement "watch" command in Coro::Debug shells.
108 - for fun, implement time-slicing as an example in the manpage.
109 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
110 Coro::Event, use the normal AnyEvent handling instead of dieing
111 (the same is true for Coro::Handle).
112 - properly document Coro::EV::timed_io_once.
113 - avoid unneccessary ->cancel calls in Coro::Handle.
114 - maybe make it work on mingw32 with win32 backend
115 (based on patch by Yasuhiro Matsumoto).
116
1175.132 Fri May 29 09:00:39 CEST 2009
118 - do not keep a reference to the argument itself in
119 Coro::Semaphore::guard, as it could change later.
120 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
121 should support a prepare callback.
122
1235.131 Mon Mar 16 23:20:37 CET 2009
124 - implement and document Coro->suspend, Coro->resume.
125 - fix Coro::Select implementation to not (often) close
126 the passed file descriptors (testcase provided by pippijn).
127
1285.13 Mon Dec 15 21:51:42 CET 2008
129 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
130 - don't set diehook to C<undef> but instead to NULL, to avoid
131 spurious warnings.
132 - fix a lot of bugs in Coro::SemaphoreSet.
133 - Coro::SemaphoreSet will less often create a semaphore needlessly.
134 - add Coro::SemaphoreSet::count and wait methods.
135 - take advantage of the new Guard module.
136 - deprecate Coro::guard.
137 - try to fix the dreaded 01_unblock tests once more. I hate it when
138 testsuites need more fixing than the code they are supposed to test.
139 - croak in more cases when a required callback isn't resolvable.
140 - fix some minor issues in Coro::State->call/eval.
141 - use current coroutine context instead of a temporary one
142 when temporarily switching to another coroutine.
143 - do not call C-level on_destroy handlers during global destruction,
144 to avoid needless segfaults.
145
1465.12 Sun Dec 7 13:30:38 CET 2008
147 - add default config for MirOS, which seems to be a bug-to-bug
148 compatible fork of openbsd ("world domination by releasing
149 openbsd cvs before the openbsd folks do it" or so :).
150 - free_padlist did destroy the names pad, not good, but didn't
151 seem to bother perl - this could fix issues such as eval ""
152 inside a function called from multiple coroutines.
153 - use a different method to detect destruction time.
154 - be more careful when freeing padlists just before global
155 destruction.
156 - fixed and expanded the call/cc example.
157 - renamed _terminate to _coro_run.
158 - new method Coro::Channel->shutdown.
159 - try pthreads on openbsd <4.4 (broken sigaltstack, will
160 pthreads fare better?).
161 - be less picky about destroying "a" running coroutine.
162
1635.11 Tue Nov 25 21:49:05 CET 2008
164 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
165 working code with failed assertions, introducing more bugs than
166 it fixes, requiring elaborate workarounds :(
167
1685.1 Mon Nov 24 08:54:59 CET 2008
169 - wrote a small introductory tutorial - Coro::Intro.
170 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
171 - Coro::Select did errornously dup the file descriptors
172 and didn't work with all AnyEvent backends.
173 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
174 LWP data transfers.
175 - disassociate c contexts from coro objects - this is agruably more
176 correct, but mostly allows sharing of cctxs between coro and state
177 objects, for added memory savings and speed increases.
178 - bumped $Coro::POOL_RSS up to 32kb by default.
179 - no longer set the optype to OP_CUSTOM, as B::* understandably
180 doesn't like this very much (and we *are* a type of entersub).
181 - implement state cloning, just to prove that call/cc can be done.
182 - automatically load Coro::AnyEvent in Coro::Handle.
183 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
184 do not have this method (and don't need it either).
185 - speed up generic anyevent methods in Coro::Handle by using rouse
186 callbacks.
187 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
188 others. It also makes the debugger happier, as you can trace
189 through the idle threads now.
190 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
191 - eg/event was pretty broken.
192 - better 5.8.6 compatibility.
193
1945.0 Thu Nov 20 10:35:05 CET 2008
195 - NEW ARCHITECTURE: use the latest 4.x version if you experience
196 stability issues.
197 - bump API version to 7 - all dependents must be recompiled.
198 - removed timed_* functions - they were not being used anyways
199 and should be replaced by a more generic mechanism -
200 and were annoying to support anyways :)
201 - removed SemaphoreSet's waiter method - use sem method instead.
202 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
203 - async_pool did free a scalar value twice
204 ("Attempt to unreference...").
205 - fix a longstanding bug where calling terminate on a coro that
206 was waiting for a semaphore that was just becoming available
207 would cause a deadlock (semaphore would get into a state where
208 it was available but waiters were still blocked).
209 - calling throw on a coroutine that is waiting for a semaphore will
210 no longer make it acquire the semaphore (and thus leak a count).
211 - perl's process emulation is now not even theoretically supported
212 anymore.
213 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
214 conversion of callback-style to blocking-style.
215 - new methods $coro->schedule_to and ->cede_to, to specifically
216 schedule or cede to a specific coroutine.
217 - new function Coro::Semaphore::wait.
218 - use named constants in Coro::Channel (Richard Hundt).
219 - directly patch the entersub opcode calling SLF functions (cede,
220 transfer and so on). this does speed up context switching, but
221 more importanly, it frees us from the hardcoded behaviour of
222 entersub, so we might actually be able to return something from
223 those functions and atcually create new ones.
224 - take advantage of __builtin_frame_address on gcc.
225 - expose THX in coroapi (not sure whether this was a wise decision,
226 as "threaded" perls are running at half speed anyways).
227 - implement execute_slf (schedule-like-function) interface that makes
228 it possible to implement schedule-like-functions in XS.
229 - use new SLF interface to massively speed up Coro::EV by roughly a
230 factor of two.
231 - used new SLF interface to massively speed up Coro::Semaphore by a
232 factor of three.
233 - used new SLF interface to speed up Coro::AIO by roughly a factor of
234 four and reduce its memory usage considerably.
235 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
236 for a nice speedup and vastly more correct behaviour. Also implement
237 a new method "sem" to get at the underlying semaphore object.
238 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
239 (in comparison) 20-40% speedup.
240 - used new SLF interface to reimplement Coro::Signal gaining
241 some unknown (because I was too lazy), but certain, speedup, and also
242 making signals reliable for the first time.
243 - used new SLF interface and other optimisations to speed up async_pool
244 by a factor of two. It also doesn't rely on perl's exception mechanism
245 to exit anymore. The overhead for terminating an async_pool, coro over
246 a normal async is now very small.
247 - sped up coroutine creation/destruction by 40%.
248 - forgot to include Coro/libcoro/README in the dist for all these years.
249 - work around a freebsd pthreads bug (manual testcancel is required as
250 pthread_cond_wait isn't a cancellation point on freebsd).
251 - use new rouse functions to speed up and simplify Coro::BDB.
252 - make "prefer perl native functions" work with threaded perls.
253 - condense Coro::Debug ps output, hint at v and w flags.
254 - (libcoro) lots of minor cleanups and portability improvements.
255
2564.914 Wed Nov 19 12:54:18 CET 2008
257 - fix a disastrous bug in the readline optimisation
258 introduced in 4.801.
259
2604.913 Sat Nov 15 07:58:28 CET 2008
261 - async_pool did free a scalar value twice
262 ("Attempt to unreference...").
263
2644.912 Thu Nov 13 18:31:23 CET 2008
265 - minor cleanups.
266 - use much larger stacks on linux and perl < 5.8.8.
267 - Coro::Debug::new_unix_server did not unlink the socket
268 when destroyed.
269
2704.911 Tue Nov 11 04:26:17 CET 2008
271 - "port" to threaded perls.
272
2734.91 Mon Nov 10 05:36:38 CET 2008
274 - the ->throw exception object no longer leaks.
275 - creating a new cctx leaked a scopestack entry (memleak).
276 - new coroutines didn't get created with a zero flags field
277 (unknown impact).
278 - calling ->throw on a not-yet-started coroutine should now work
279 instead of being ignored.
280 - ->throw is now supported on Coro::State objects.
281 - clean up cctx creation code a bit.
282 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
283
2844.9 Sat Nov 8 17:45:27 CET 2008
285 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
286 - (libcoro) no longer leak threads in the experimental pthread backend,
287 also speed it up considerably.
288 - (libcoro) do not rely on makecontext passing void *'s unscathed.
289 - fix compiletime dependencies on libcoro in the Makefile.
290 - cctx_count wasn't always updated properly.
291 - Coro::State::cctx_stacksize wasn't applied correctly.
292 - new function Coro::State::cctx_max_idle.
293 - the default max number of idle C contexts is now 4.
294 - (libcoro) try harder to get _setjmp/_longjmp.
295 - (libcoro) cleanup and extend the libcoro API to officially
296 allow the creation of empty source contexts.
297 - very experimental workaround for the totally broken netbsd platform.
298 - tried to hack around openbsd bugs.
299
3004.804 Wed Nov 5 16:36:00 CET 2008
301 - Coro::Debug::new_unix_server would not create a non-blocking listening
302 socket, sometimes causing freezes.
303 - (libcoro) fix misaligned stack points for setjmp and assembly
304 methods, which can cause crashes on x86/x86_64 with a sufficiently
305 aggressive compiler.
306 - new function: Coro::Debug::new_tcp_server.
307 - move ->throw into the Coro class because it only works on coro objects.
308
3094.803 Mon Nov 3 17:16:12 CET 2008
310 - (libcoro) use a global asm statement to become independent of gcc
311 otpimisations for CORO_ASM (thanks to pippijn for the idea).
312 - try to workaround yet another broken bsd, this time dragonfly.
313
3144.802 Thu Oct 30 10:56:12 CET 2008
315 - support -fno-omit-frame-pointer on x86 with the assembly method.
316 - tune 01_unblock.t tests a bit.
317
3184.801 Wed Oct 22 18:33:37 CEST 2008
319 - improve readline speed for very long "lines".
320 - backport to 5.8.8.
321
3224.8 Thu Oct 2 13:34:40 CEST 2008
323 - new function Coro::AIO::aio_wait.
324 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
325 - greatly speed up and reduce memory usage of Coro::AIO requests.
326 - implement some other µ-optimisations.
327
3284.749 Mon Sep 29 14:40:12 CEST 2008
329 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
330
3314.748 Sat Sep 27 14:03:19 CEST 2008
332 - implement, but do not document, PerlIO::cede(granularity).
333 - Coro::Storable forgot to wrap Storable::pstore.
334 - work around the multitude of leaks and memory corruption
335 bugs in PerlIO::via by using our own C-level perliol. As a side
336 effect, Coro::Storable is now much, much, much faster.
337
3384.747 Tue Sep 23 01:59:41 CEST 2008
339 - fix a per-cv memleak (one empty array was leaked per
340 code reference).
341 - avoid a crash in coro->call|rss when the coroutine was already
342 destroyed (most noticably when using Coro::Debug::ps :)
343 - also protect *Storable::FILE.
344 - push up default storable granularity to 20ms.
345
3464.746 Sun Sep 21 03:22:20 CEST 2008
347 - be more insistent on locking Storable against reentrancy
348 in Coro::Storable.
349 - move swap_def?v and throw to Coro::State, as documented.
350
3514.745 Thu Jul 24 00:14:38 CEST 2008
352 - remove debugging code related to MgPV_nolen_const, also try to
353 make it compile with perl 5.8.6 (yes, apple apparently loves
354 outdated software). Reported by John S.
355
3564.744 Tue Jul 8 22:06:35 CEST 2008
357 - correctly provide default DIE/WARN handlers as documented.
358 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
359 implementations inside perl work fine for us.
360
3614.743 Mon Jun 16 00:21:57 CEST 2008
362 - when using Coro::EV without running EV::loop it could
363 result in busy-waiting for events, this has been fixed.
364 - reduce codesize and improve performance by using EV_DEFAULT_UC.
365
3664.742 Sat May 31 14:10:21 CEST 2008
367 - implement a workaround for (some) perl <5.8.8 versions.
368 - require EV 3.3+.
369
3704.741 Fri May 30 23:33:09 CEST 2008
371 - tell netbsd how utterly broken their imitation of an OS is
372 and refuse to build by default if pthreads are in use.
373 - switch to "s" method on all bsd's by default, as their ucontext
374 stuff seems just too broken.
375 - fix a bug in Coro::Select.
376
3774.74 Thu May 29 20:05:31 CEST 2008
378 - do not test Coro::LWP for lack of dependencies.
379 - do not test Coro::Select for lack of working perls.
380
3814.73 Thu May 29 2008
382 - fix a bug in Coro::EV which would cause it to block despite
383 there being runnable coroutines.
384 - sprinkle "no warnings" freely over everything, also suppress
385 warnings for some other modules.
386 - fix typo in WSAEWOULDBLOCK.
387
3884.72 Sun May 25 05:14:36 CEST 2008
389 - tweak META.yaml a bit, unfortunately, there is no documented way
390 to have optional dependencies with CPAN. doh :(
391 - avoid running some tests on windows because they would fail due to
392 perl bug (broken fork, broken pipes...).
393 - work around perl on windows bugs where perl returns undocumented
394 error codes for sysread, syswrite etc. by taking advantage
395 of AnyEvent's workaround for that problem.
396 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
397 a common perl implementation bug on windows.
398 - use unix domain sockets in testsuite to work around
399 common perl implementation bugs on widows (they are emulated by
400 tcp sockets on windows. ugh.)
401
4024.71 Sat May 24 20:01:27 CEST 2008
403 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
404 - take advantage of async name resolution of AnyEvent::Util.
405 - work around brutal inet_aton override in Coro::LWP.
406 - take advantage of the readyhook in Coro::EV, for smoother
407 scheduling.
408
4094.7 Sun May 11 00:32:19 CEST 2008
410 - completely reworked the Coro manpage.
411 - added Coro::AnyEvent, generic event loop integration.
412 - implement cancel, ready and kill commands in Coro::Debug.
413 - document find_coro in Coro::Debug.
414 - incompatible change: rename has_stack to has_cctx.
415 - Coro::AIO and Coro::BDB no longer force event model detection,
416 use AnyEvent::AIO and AnyEvent::BDB.
417
4184.6 Sat Apr 26 10:05:14 CEST 2008
419 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
420 by the Coro module. It was a mistake to have it in the first place.
421 - (experimental) support for activestate perl 5.10 (method "w").
422 - (experimental) support for strawberry perl (method "a").
423 - coro_sigelem_set did not return a value although it had to,
424 actual impact unknown.
425
4264.51 Mon Apr 14 13:28:27 CEST 2008
427 - make it compile again on 5.8.
428
4294.50 Thu Apr 10 09:43:17 CEST 2008
430 - I did it twice! (see 4.49).
431
4324.49 Sun Apr 6 21:23:31 CEST 2008
433 - grr, instead of compiling the recent changes on 5.10 only they
434 were compiled on 5.8 only.
435
4364.48 Sun Apr 6 20:36:46 CEST 2008
437 - allow coroutine switches during eval's under 5.10.x, as it seems
438 the parser is a per-interpreter option now, so this is safe
439 (this might fix the odd crashing bug).
440 - drop support for 5.9.x versions: they are dead, jim.

4424.47 Sun Apr 6 00:37:52 CEST 2008
443 - force cctx allocation on API calls: we know we need to force one
444 and gcc actually manages to confuse our heuristic nowadays,
445 leading to crashes and worse.
446 - document force_cctx.
447
4484.46 Fri Apr 4 22:05:43 CEST 2008
449 - upgrade libcoro, resulting in pthread-backend (which was only created
450 to fulfill the rules of the programming languages shootout).
451
4524.45 Thu Mar 13 11:55:36 CET 2008
453 - fix a file leaking bug in eg/mhyttpd that would allow
454 downloading of any file (reported by oesi).
455 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
456 (also add testcase).
457 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
458 apparently having loads of fun with that).
459 - implement $state->swap_defsv, ->swap_defav and document ->throw.
460
4614.4 Wed Feb 13 16:44:29 CET 2008
462 - only assume .cfi pseudo isns exist on GNU/Linux.
463 - add get_timed method to Coro::Channels.
464 - fixed Coro::Debug manpage.
465 - perl 5.11 compatbility improvement based on patch by
466 Andreas König.
467
4684.37 Sun Jan 20 11:25:23 CET 2008
469 - soften the check for an active parser for perl 5.10 (avoiding
470 "Coro::State::transfer called while parsing" in many cases).
471
4724.36 Sun Jan 13 10:53:56 CET 2008
473 - reset diehook when terminating from an async_pool as to not
474 trigger any __DIE__ handlers.
475
4764.35 Sun Jan 13 04:14:13 CET 2008
477 - "bt" debug command now displays any exceptions
478 from longmess and also skips the innermost
479 stackframes, giving more useufl output.
480 - allow backtraces in coroutines blocked in Coro::EV,
481 at a <1% speed hit.
482 - handle localising of $SIG{__WARN__} and __DIE__
483 properly (with a proper amount of dirty hacking).
484
4854.34 Sat Dec 22 17:49:53 CET 2007
486 - upgrade to EV version 2.0 API.
487
4884.33 Mon Dec 17 08:36:12 CET 2007
489 - make Coro::AIO etc. loadable in the absence of EV.
490
4914.32 Mon Dec 17 07:46:02 CET 2007
492 - majorly improved Coro::Handle's performance with Coro::EV.
493 - implemented the until now mythical Coro::BDB module.
494 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
495
4964.31 Wed Dec 5 12:32:39 CET 2007
497 - remove warn statement form Coro::Util.
498
4994.3 Tue Dec 4 20:33:14 CET 2007
500 - calls to the idle function could cause stack corruption
501 when the stack changed.
502 - do no longer rely on the presence of EV::DNS if EV is used
503 (because it is gone), but instead take avdantage of EV::ADNS
504 if available.
505 - add ($) prototypes to all functions in Coro::Storable.
506 - use a conventional (safer) idle callback in Coro::EV.
507 - do accept quickly in Coro::Debug to avoid endless loops.
508
5094.22 Fri Nov 30 16:04:04 CET 2007
510 - really use optimised versions for Event and EV in Coro::Util
511 and Coro::Handle.
512
5134.21 Sun Nov 25 10:48:59 CET 2007
514 - fix a spurious memory read.
515 - Coro::EV no longer keeps the eventloop "alive".
516
5174.2 Fri Nov 9 20:47:05 CET 2007
518 - enable/disable tracing from a new coroutine, not a pooled one.
519 - fix a memleak in Coro::Event.
520 - removed killall call from fork_eval.
521 - made sure store_fd is already loaded so that fork_eval
522 does not have to parse autoload in each subprocess.
523 - only use assembly method if -O switch is in $Config{optimize}.
524 - add (optional) Coro::EV module, so far the best event loop module
525 directly supported by Coro.
526 - if the event model is EV, use EV::DNS to resolve
527 stuff in Coro::Util.
528 - don't get confused by multiple event notifications in Coro::Handle.
529 - initial support for EV (libevent interface).
530 - require Event and EV using configure_requires, to force their existance.
531
5324.13 Wed Oct 24 07:26:45 CEST 2007
533 - add Coro::Storable::blocking_thaw.
534 - use a vastly more complicated technique to localise
535 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
536 - use a coroutine for the idle callback Coro::Event,
537 instead of running Event in the current coroutine context.
538 This also catches recursive invocations.
539 - actually report fork errors in gethostbyname and inet_aton.
540
5414.11 Thu Oct 11 02:40:24 CEST 2007
542 - port to threaded perls.
543
5444.1 Thu Oct 11 02:38:16 CEST 2007
545 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
546 be local to each coro (see Coro::State).
547 - incompatible change: for very deep reasons, cede and cede_notself
548 cannot return anything, so nothing will be returned.
549 - possibly bring back 5.10 compatibility (untested).
550 - work around stupid (and wrong) warning on 5.10 :(.
551 - overlay the saved state over the context stack. This saves
552 a few hundred bytes per coroutine on average and also
553 speeds up context switching a bit.
554 - further tune default stack sizes.
555 - (more) correctly calculate stack usage in coro_rss.
556 - Coro::Storable::blocking_* did not properly lock
557 resulting in races between coroutines.
558 - added Coro::Storable::guard.
559 - stopping to trace a coroutine could destroy the cctx of
560 an unrelated coroutine.
561 - explain the relationship between Perl and C coroutines in
562 more detail in Coro::State.
563 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
564 causing a fork per resolve. This also affected Coro::Socket.
565 - switch to a separate stack in $coro->call/eval to avoid
566 invalidating pointers.
567
5684.03 Sat Oct 6 21:24:00 CEST 2007
569 - added Coro::throw method.
570 - minor code cleanups.
571
5724.02 Sat Oct 6 02:36:47 CEST 2007
573 - fix a very minor per-coroutine memleak (a single codereference).
574 - fixed a bug where the currently in-use c context would be freed
575 prematurely (can happen only when programs change the stacksize
576 or use tracing).
577 - tracing can no longer keep a coro alive after it terminated.
578 - do static branch prediction in the common path for gcc. gives
579 about 2-5% speed improvement here.
580
5814.01 Fri Oct 5 22:10:49 CEST 2007
582 - instead of recreating *a* standard output handle we simply
583 use STDOUT, which is faster and hopefully more robust.
584
5854.0 Fri Oct 5 12:56:00 CEST 2007
11 - incompatibly changed Coro::Storable::freeze. 586 - incompatibly changed Coro::Storable::freeze.
12 - added Coro::Debug, interactive coroutine debugging. 587 - major new feature: added Coro::Debug, for interactive coroutine
588 debugging, tracing and much more.
589 - major bug fix: unbelievable, but true: $_, $/ and many other
590 "saved" variables actually weren't being saved. This has been fixed,
591 of course, while increasing performance while losing all the save
592 flags.
593 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 594 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 595 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 596 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
597 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 598 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool 599 - better async_pool resource management, moved parts of async_pool
18 handling to XS. 600 handling to XS (major speed improvement).
601 - actually croak before modifying important data structures.
602 - refuse to transfer while compiling.
603 - possibly support eval EXPR better now.
604 - enable assembly per default on linux+bsd x86+amd64.
605 - all internal members were renamed _something for easier subclassing.
19 - many minor tweaks. 606 - many minor tweaks.

213.63 Wed May 16 14:10:06 CEST 2007 6083.63 Wed May 16 14:10:06 CEST 2007
22 - implement handcoded assembly for x86/amd64 SVR ABI. 609 - implement handcoded assembly for x86/amd64 SVR ABI.
