93.8 11 - Coro::Storable destroyed the prototypes of the functions it wrapped.
12 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
13 - added section on "windows process emulation" to the manpage,
14 after a not-so-fruitful (nor-friendly) "discussion" with chip
15 salzenberg (discussion implies arguments, but his only arguments
16 were ad-hominems, one wonders why he started it in the first
17 place). I hope this explains it well enough for him to understand,
18 and maybe well enough for others to understand.
19 - use common::sense everywhere now.
20
215.17 Sat Aug 22 23:09:31 CEST 2009
22 - work around a bug in the perl debugger causing crashes
23 when running under the debugger by marking _pool_handler as nodebug.
24 - speed up Coro::async considerably.
25 - try some hacks to get netbsd to work "more often" - their broken
26 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
27 - convert Coro to AE 5.0 API.
28
295.162 Tue Jul 28 04:04:03 CEST 2009
30 - perl 5.8.2 is now minimum requirement.
31 - skip t/19_handle.t on broken windows perls.
32
335.161 Wed Jul 22 04:47:38 CEST 2009
34 - Coro::AnyEvent::poll could have a different prototype when EV was
35 used as backend (analyzed by Tatsuhiko Miyagawa).
36 - Coro::AnyEvent errornously initialised the event loop when loaded,
37 not on demand.
38 - try to workaround rare */t/01_unblock.t failures.
39
405.16 Tue Jul 21 01:44:37 CEST 2009
41 - Coro::AnyEvent failed to hook into the event loop
42 when no threads had been readied between detecting
43 the event loop and actually running it.
44 - considerably speed up Coro::Select by taking avdantage
45 of AnyEvent > 4.8 and some other optimisations.
46 - implement paragraph readline mode in Coro::Handle
47 (based on patches by Zsbán Ambrus).
48 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
49 and analyzed by Yasuhiro MATSUMOTO).
50 - clarified libcoro license and copyright.
51 - someone stole my EXTRA_META!!!
52 - implement Coro::Select::patch_pp_sselect and it's brother,
53 for hardcode select overriding.
54
555.151 Mon Jul 6 05:41:57 CEST 2009
56 - backport to windows process emulation code again (patch by
57 Yasuhiro MATSUMOTO).
58 - slightly update Coro::MakeMaker.
59
605.15 Tue Jun 30 10:28:06 CEST 2009
61 - deprecate Coro::Socket, document how to get ipv6 support via
62 AnyEvent::Socket instead.
63 - implement signal->wait ($cb) interface, similar to semaphores.
64 - work around SvOK not supporting getmagic, so we have to getmagic
65 to test for undef :/ (reported by Matthias Waldorf).
66 - load Coro::AnyEvent in all modules using AnyEvent.
67 - work around perl corrupting our internal data structures,
68 reported by Tokuhiro Matsuno.
69 - enable per-coroutine real and cpu time gathering
70 (Coro::State::enable_times).
71
725.14 Wed Jun 24 01:37:48 CEST 2009
73 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
74 as this seems to have been a difficult concept (poll, sleep, idle,
75 idle_upto).
76 - add Coro::AnyEvent::readable/writable functions.
77 - clarify Coro::EV/Event/AnyEvent manpages.
78 - free per-thread global scalars in the thread calling ->cancel, to
79 avoid crashes when $_, $@ etc., are magical but some of those
80 had already been freed.
81 - "unexperimentalise" the callback interface for Coro::Semaphore.
82 - speed up ready queue management/context switching by using a linked
83 list instead of an array (~5-10%).
84 - implement "watch" command in Coro::Debug shells.
85 - for fun, implement time-slicing as an example in the manpage.
86 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
87 Coro::Event, use the normal AnyEvent handling instead of dieing
88 (the same is true for Coro::Handle).
89 - properly document Coro::EV::timed_io_once.
90 - avoid unneccessary ->cancel calls in Coro::Handle.
91 - maybe make it work on mingw32 with win32 backend
92 (based on patch by Yasuhiro Matsumoto).
93
945.132 Fri May 29 09:00:39 CEST 2009
95 - do not keep a reference to the argument itself in
96 Coro::Semaphore::guard, as it could change later.
97 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
98 should support a prepare callback.
99
1005.131 Mon Mar 16 23:20:37 CET 2009
101 - implement and document Coro->suspend, Coro->resume.
102 - fix Coro::Select implementation to not (often) close
103 the passed file descriptors (testcase provided by pippijn).
104
1055.13 Mon Dec 15 21:51:42 CET 2008
106 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
107 - don't set diehook to C<undef> but instead to NULL, to avoid
108 spurious warnings.
109 - fix a lot of bugs in Coro::SemaphoreSet.
110 - Coro::SemaphoreSet will less often create a semaphore needlessly.
111 - add Coro::SemaphoreSet::count and wait methods.
112 - take advantage of the new Guard module.
113 - deprecate Coro::guard.
114 - try to fix the dreaded 01_unblock tests once more. I hate it when
115 testsuites need more fixing than the code they are supposed to test.
116 - croak in more cases when a required callback isn't resolvable.
117 - fix some minor issues in Coro::State->call/eval.
118 - use current coroutine context instead of a temporary one
119 when temporarily switching to another coroutine.
120 - do not call C-level on_destroy handlers during global destruction,
121 to avoid needless segfaults.
122
1235.12 Sun Dec 7 13:30:38 CET 2008
124 - add default config for MirOS, which seems to be a bug-to-bug
125 compatible fork of openbsd ("world domination by releasing
126 openbsd cvs before the openbsd folks do it" or so :).
127 - free_padlist did destroy the names pad, not good, but didn't
128 seem to bother perl - this could fix issues such as eval ""
129 inside a function called from multiple coroutines.
130 - use a different method to detect destruction time.
131 - be more careful when freeing padlists just before global
132 destruction.
133 - fixed and expanded the call/cc example.
134 - renamed _terminate to _coro_run.
135 - new method Coro::Channel->shutdown.
136 - try pthreads on openbsd <4.4 (broken sigaltstack, will
137 pthreads fare better?).
138 - be less picky about destroying "a" running coroutine.
139
1405.11 Tue Nov 25 21:49:05 CET 2008
141 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
142 working code with failed assertions, introducing more bugs than
143 it fixes, requiring elaborate workarounds :(
144
1455.1 Mon Nov 24 08:54:59 CET 2008
146 - wrote a small introductory tutorial - Coro::Intro.
147 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
148 - Coro::Select did errornously dup the file descriptors
149 and didn't work with all AnyEvent backends.
150 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
151 LWP data transfers.
152 - disassociate c contexts from coro objects - this is agruably more
153 correct, but mostly allows sharing of cctxs between coro and state
154 objects, for added memory savings and speed increases.
155 - bumped $Coro::POOL_RSS up to 32kb by default.
156 - no longer set the optype to OP_CUSTOM, as B::* understandably
157 doesn't like this very much (and we *are* a type of entersub).
158 - implement state cloning, just to prove that call/cc can be done.
159 - automatically load Coro::AnyEvent in Coro::Handle.
160 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
161 do not have this method (and don't need it either).
162 - speed up generic anyevent methods in Coro::Handle by using rouse
163 callbacks.
164 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
165 others. It also makes the debugger happier, as you can trace
166 through the idle threads now.
167 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
168 - eg/event was pretty broken.
169 - better 5.8.6 compatibility.
170
1715.0 Thu Nov 20 10:35:05 CET 2008
172 - NEW ARCHITECTURE: use the latest 4.x version if you experience
173 stability issues.
174 - bump API version to 7 - all dependents must be recompiled.
175 - removed timed_* functions - they were not being used anyways
176 and should be replaced by a more generic mechanism -
177 and were annoying to support anyways :)
178 - removed SemaphoreSet's waiter method - use sem method instead.
179 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
180 - async_pool did free a scalar value twice
181 ("Attempt to unreference...").
182 - fix a longstanding bug where calling terminate on a coro that
183 was waiting for a semaphore that was just becoming available
184 would cause a deadlock (semaphore would get into a state where
185 it was available but waiters were still blocked).
186 - calling throw on a coroutine that is waiting for a semaphore will
187 no longer make it acquire the semaphore (and thus leak a count).
188 - perl's process emulation is now not even theoretically supported
189 anymore.
190 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
191 conversion of callback-style to blocking-style.
192 - new methods $coro->schedule_to and ->cede_to, to specifically
193 schedule or cede to a specific coroutine.
194 - new function Coro::Semaphore::wait.
195 - use named constants in Coro::Channel (Richard Hundt).
196 - directly patch the entersub opcode calling SLF functions (cede,
197 transfer and so on). this does speed up context switching, but
198 more importanly, it frees us from the hardcoded behaviour of
199 entersub, so we might actually be able to return something from
200 those functions and atcually create new ones.
201 - take advantage of __builtin_frame_address on gcc.
202 - expose THX in coroapi (not sure whether this was a wise decision,
203 as "threaded" perls are running at half speed anyways).
204 - implement execute_slf (schedule-like-function) interface that makes
205 it possible to implement schedule-like-functions in XS.
206 - use new SLF interface to massively speed up Coro::EV by roughly a
207 factor of two.
208 - used new SLF interface to massively speed up Coro::Semaphore by a
209 factor of three.
210 - used new SLF interface to speed up Coro::AIO by roughly a factor of
211 four and reduce its memory usage considerably.
212 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
213 for a nice speedup and vastly more correct behaviour. Also implement
214 a new method "sem" to get at the underlying semaphore object.
215 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
216 (in comparison) 20-40% speedup.
217 - used new SLF interface to reimplement Coro::Signal gaining
218 some unknown (because I was too lazy), but certain, speedup, and also
219 making signals reliable for the first time.
220 - used new SLF interface and other optimisations to speed up async_pool
221 by a factor of two. It also doesn't rely on perl's exception mechanism
222 to exit anymore. The overhead for terminating an async_pool, coro over
223 a normal async is now very small.
224 - sped up coroutine creation/destruction by 40%.
225 - forgot to include Coro/libcoro/README in the dist for all these years.
226 - work around a freebsd pthreads bug (manual testcancel is required as
227 pthread_cond_wait isn't a cancellation point on freebsd).
228 - use new rouse functions to speed up and simplify Coro::BDB.
229 - make "prefer perl native functions" work with threaded perls.
230 - condense Coro::Debug ps output, hint at v and w flags.
231 - (libcoro) lots of minor cleanups and portability improvements.
232
2334.914 Wed Nov 19 12:54:18 CET 2008
234 - fix a disastrous bug in the readline optimisation
235 introduced in 4.801.
236
2374.913 Sat Nov 15 07:58:28 CET 2008
238 - async_pool did free a scalar value twice
239 ("Attempt to unreference...").
240
2414.912 Thu Nov 13 18:31:23 CET 2008
242 - minor cleanups.
243 - use much larger stacks on linux and perl < 5.8.8.
244 - Coro::Debug::new_unix_server did not unlink the socket
245 when destroyed.
246
2474.911 Tue Nov 11 04:26:17 CET 2008
248 - "port" to threaded perls.
249
2504.91 Mon Nov 10 05:36:38 CET 2008
251 - the ->throw exception object no longer leaks.
252 - creating a new cctx leaked a scopestack entry (memleak).
253 - new coroutines didn't get created with a zero flags field
254 (unknown impact).
255 - calling ->throw on a not-yet-started coroutine should now work
256 instead of being ignored.
257 - ->throw is now supported on Coro::State objects.
258 - clean up cctx creation code a bit.
259 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
260
2614.9 Sat Nov 8 17:45:27 CET 2008
262 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
263 - (libcoro) no longer leak threads in the experimental pthread backend,
264 also speed it up considerably.
265 - (libcoro) do not rely on makecontext passing void *'s unscathed.
266 - fix compiletime dependencies on libcoro in the Makefile.
267 - cctx_count wasn't always updated properly.
268 - Coro::State::cctx_stacksize wasn't applied correctly.
269 - new function Coro::State::cctx_max_idle.
270 - the default max number of idle C contexts is now 4.
271 - (libcoro) try harder to get _setjmp/_longjmp.
272 - (libcoro) cleanup and extend the libcoro API to officially
273 allow the creation of empty source contexts.
274 - very experimental workaround for the totally broken netbsd platform.
275 - tried to hack around openbsd bugs.
276
2774.804 Wed Nov 5 16:36:00 CET 2008
278 - Coro::Debug::new_unix_server would not create a non-blocking listening
279 socket, sometimes causing freezes.
280 - (libcoro) fix misaligned stack points for setjmp and assembly
281 methods, which can cause crashes on x86/x86_64 with a sufficiently
282 aggressive compiler.
283 - new function: Coro::Debug::new_tcp_server.
284 - move ->throw into the Coro class because it only works on coro objects.
285
2864.803 Mon Nov 3 17:16:12 CET 2008
287 - (libcoro) use a global asm statement to become independent of gcc
288 otpimisations for CORO_ASM (thanks to pippijn for the idea).
289 - try to workaround yet another broken bsd, this time dragonfly.
290
2914.802 Thu Oct 30 10:56:12 CET 2008
292 - support -fno-omit-frame-pointer on x86 with the assembly method.
293 - tune 01_unblock.t tests a bit.
294
2954.801 Wed Oct 22 18:33:37 CEST 2008
296 - improve readline speed for very long "lines".
297 - backport to 5.8.8.
298
2994.8 Thu Oct 2 13:34:40 CEST 2008
300 - new function Coro::AIO::aio_wait.
301 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
302 - greatly speed up and reduce memory usage of Coro::AIO requests.
303 - implement some other µ-optimisations.
304
3054.749 Mon Sep 29 14:40:12 CEST 2008
306 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
307
3084.748 Sat Sep 27 14:03:19 CEST 2008
309 - implement, but do not document, PerlIO::cede(granularity).
310 - Coro::Storable forgot to wrap Storable::pstore.
311 - work around the multitude of leaks and memory corruption
312 bugs in PerlIO::via by using our own C-level perliol. As a side
313 effect, Coro::Storable is now much, much, much faster.
314
3154.747 Tue Sep 23 01:59:41 CEST 2008
316 - fix a per-cv memleak (one empty array was leaked per
317 code reference).
318 - avoid a crash in coro->call|rss when the coroutine was already
319 destroyed (most noticably when using Coro::Debug::ps :)
320 - also protect *Storable::FILE.
321 - push up default storable granularity to 20ms.
322
3234.746 Sun Sep 21 03:22:20 CEST 2008
324 - be more insistent on locking Storable against reentrancy
325 in Coro::Storable.
326 - move swap_def?v and throw to Coro::State, as documented.
327
3284.745 Thu Jul 24 00:14:38 CEST 2008
329 - remove debugging code related to MgPV_nolen_const, also try to
330 make it compile with perl 5.8.6 (yes, apple apparently loves
331 outdated software). Reported by John S.
332
3334.744 Tue Jul 8 22:06:35 CEST 2008
334 - correctly provide default DIE/WARN handlers as documented.
335 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
336 implementations inside perl work fine for us.
337
3384.743 Mon Jun 16 00:21:57 CEST 2008
339 - when using Coro::EV without running EV::loop it could
340 result in busy-waiting for events, this has been fixed.
341 - reduce codesize and improve performance by using EV_DEFAULT_UC.
342
3434.742 Sat May 31 14:10:21 CEST 2008
344 - implement a workaround for (some) perl <5.8.8 versions.
345 - require EV 3.3+.
346
3474.741 Fri May 30 23:33:09 CEST 2008
348 - tell netbsd how utterly broken their imitation of an OS is
349 and refuse to build by default if pthreads are in use.
350 - switch to "s" method on all bsd's by default, as their ucontext
351 stuff seems just too broken.
352 - fix a bug in Coro::Select.
353
3544.74 Thu May 29 20:05:31 CEST 2008
355 - do not test Coro::LWP for lack of dependencies.
356 - do not test Coro::Select for lack of working perls.
357
3584.73 Thu May 29 2008
359 - fix a bug in Coro::EV which would cause it to block despite
360 there being runnable coroutines.
361 - sprinkle "no warnings" freely over everything, also suppress
362 warnings for some other modules.
363 - fix typo in WSAEWOULDBLOCK.
364
3654.72 Sun May 25 05:14:36 CEST 2008
366 - tweak META.yaml a bit, unfortunately, there is no documented way
367 to have optional dependencies with CPAN. doh :(
368 - avoid running some tests on windows because they would fail due to
369 perl bug (broken fork, broken pipes...).
370 - work around perl on windows bugs where perl returns undocumented
371 error codes for sysread, syswrite etc. by taking advantage
372 of AnyEvent's workaround for that problem.
373 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
374 a common perl implementation bug on windows.
375 - use unix domain sockets in testsuite to work around
376 common perl implementation bugs on widows (they are emulated by
377 tcp sockets on windows. ugh.)
378
3794.71 Sat May 24 20:01:27 CEST 2008
380 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
381 - take advantage of async name resolution of AnyEvent::Util.
382 - work around brutal inet_aton override in Coro::LWP.
383 - take advantage of the readyhook in Coro::EV, for smoother
384 scheduling.
385
3864.7 Sun May 11 00:32:19 CEST 2008
387 - completely reworked the Coro manpage.
388 - added Coro::AnyEvent, generic event loop integration.
389 - implement cancel, ready and kill commands in Coro::Debug.
390 - document find_coro in Coro::Debug.
391 - incompatible change: rename has_stack to has_cctx.
392 - Coro::AIO and Coro::BDB no longer force event model detection,
393 use AnyEvent::AIO and AnyEvent::BDB.
394
3954.6 Sat Apr 26 10:05:14 CEST 2008
396 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
397 by the Coro module. It was a mistake to have it in the first place.
398 - (experimental) support for activestate perl 5.10 (method "w").
399 - (experimental) support for strawberry perl (method "a").
400 - coro_sigelem_set did not return a value although it had to,
401 actual impact unknown.
402
4034.51 Mon Apr 14 13:28:27 CEST 2008
404 - make it compile again on 5.8.
405
4064.50 Thu Apr 10 09:43:17 CEST 2008
407 - I did it twice! (see 4.49).
408
4094.49 Sun Apr 6 21:23:31 CEST 2008
410 - grr, instead of compiling the recent changes on 5.10 only they
411 were compiled on 5.8 only.
412
4134.48 Sun Apr 6 20:36:46 CEST 2008
414 - allow coroutine switches during eval's under 5.10.x, as it seems
415 the parser is a per-interpreter option now, so this is safe
416 (this might fix the odd crashing bug).
417 - drop support for 5.9.x versions: they are dead, jim.
418
4194.47 Sun Apr 6 00:37:52 CEST 2008
420 - force cctx allocation on API calls: we know we need to force one
421 and gcc actually manages to confuse our heuristic nowadays,
422 leading to crashes and worse.
423 - document force_cctx.
424
4254.46 Fri Apr 4 22:05:43 CEST 2008
426 - upgrade libcoro, resulting in pthread-backend (which was only created
427 to fulfill the rules of the programming languages shootout).
428
4294.45 Thu Mar 13 11:55:36 CET 2008
430 - fix a file leaking bug in eg/mhyttpd that would allow
431 downloading of any file (reported by oesi).
432 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
433 (also add testcase).
434 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
435 apparently having loads of fun with that).
436 - implement $state->swap_defsv, ->swap_defav and document ->throw.
437
4384.4 Wed Feb 13 16:44:29 CET 2008
439 - only assume .cfi pseudo isns exist on GNU/Linux.
440 - add get_timed method to Coro::Channels.
441 - fixed Coro::Debug manpage.
442 - perl 5.11 compatbility improvement based on patch by

4454.37 Sun Jan 20 11:25:23 CET 2008
446 - soften the check for an active parser for perl 5.10 (avoiding
447 "Coro::State::transfer called while parsing" in many cases).
448
4494.36 Sun Jan 13 10:53:56 CET 2008
450 - reset diehook when terminating from an async_pool as to not
451 trigger any __DIE__ handlers.
452
4534.35 Sun Jan 13 04:14:13 CET 2008
454 - "bt" debug command now displays any exceptions
455 from longmess and also skips the innermost
456 stackframes, giving more useufl output.
457 - allow backtraces in coroutines blocked in Coro::EV,
458 at a <1% speed hit.
459 - handle localising of $SIG{__WARN__} and __DIE__
460 properly (with a proper amount of dirty hacking).
461
4624.34 Sat Dec 22 17:49:53 CET 2007
463 - upgrade to EV version 2.0 API.
464
4654.33 Mon Dec 17 08:36:12 CET 2007
466 - make Coro::AIO etc. loadable in the absence of EV.
467
4684.32 Mon Dec 17 07:46:02 CET 2007
469 - majorly improved Coro::Handle's performance with Coro::EV.
470 - implemented the until now mythical Coro::BDB module.
471 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
472
4734.31 Wed Dec 5 12:32:39 CET 2007
474 - remove warn statement form Coro::Util.
475
4764.3 Tue Dec 4 20:33:14 CET 2007
477 - calls to the idle function could cause stack corruption
478 when the stack changed.
479 - do no longer rely on the presence of EV::DNS if EV is used
480 (because it is gone), but instead take avdantage of EV::ADNS
481 if available.
482 - add ($) prototypes to all functions in Coro::Storable.
483 - use a conventional (safer) idle callback in Coro::EV.
484 - do accept quickly in Coro::Debug to avoid endless loops.
485
4864.22 Fri Nov 30 16:04:04 CET 2007
487 - really use optimised versions for Event and EV in Coro::Util
488 and Coro::Handle.
489
4904.21 Sun Nov 25 10:48:59 CET 2007
491 - fix a spurious memory read.
492 - Coro::EV no longer keeps the eventloop "alive".
493
4944.2 Fri Nov 9 20:47:05 CET 2007
495 - enable/disable tracing from a new coroutine, not a pooled one.
496 - fix a memleak in Coro::Event.
497 - removed killall call from fork_eval.
498 - made sure store_fd is already loaded so that fork_eval
499 does not have to parse autoload in each subprocess.
500 - only use assembly method if -O switch is in $Config{optimize}.
501 - add (optional) Coro::EV module, so far the best event loop module
502 directly supported by Coro.
503 - if the event model is EV, use EV::DNS to resolve
504 stuff in Coro::Util.
505 - don't get confused by multiple event notifications in Coro::Handle.
506 - initial support for EV (libevent interface).
507 - require Event and EV using configure_requires, to force their existance.
508
5094.13 Wed Oct 24 07:26:45 CEST 2007
510 - add Coro::Storable::blocking_thaw.
511 - use a vastly more complicated technique to localise
512 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
513 - use a coroutine for the idle callback Coro::Event,
514 instead of running Event in the current coroutine context.
515 This also catches recursive invocations.
516 - actually report fork errors in gethostbyname and inet_aton.
517
5184.11 Thu Oct 11 02:40:24 CEST 2007
519 - port to threaded perls.
520
5214.1 Thu Oct 11 02:38:16 CEST 2007
522 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
523 be local to each coro (see Coro::State).
524 - incompatible change: for very deep reasons, cede and cede_notself
525 cannot return anything, so nothing will be returned.
526 - possibly bring back 5.10 compatibility (untested).
527 - work around stupid (and wrong) warning on 5.10 :(.
528 - overlay the saved state over the context stack. This saves
529 a few hundred bytes per coroutine on average and also
530 speeds up context switching a bit.
531 - further tune default stack sizes.
532 - (more) correctly calculate stack usage in coro_rss.
533 - Coro::Storable::blocking_* did not properly lock
534 resulting in races between coroutines.
535 - added Coro::Storable::guard.
536 - stopping to trace a coroutine could destroy the cctx of
537 an unrelated coroutine.
538 - explain the relationship between Perl and C coroutines in
539 more detail in Coro::State.
540 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
541 causing a fork per resolve. This also affected Coro::Socket.
542 - switch to a separate stack in $coro->call/eval to avoid
543 invalidating pointers.
544
5454.03 Sat Oct 6 21:24:00 CEST 2007
546 - added Coro::throw method.
547 - minor code cleanups.
548
5494.02 Sat Oct 6 02:36:47 CEST 2007
550 - fix a very minor per-coroutine memleak (a single codereference).
551 - fixed a bug where the currently in-use c context would be freed
552 prematurely (can happen only when programs change the stacksize
553 or use tracing).
554 - tracing can no longer keep a coro alive after it terminated.
555 - do static branch prediction in the common path for gcc. gives
556 about 2-5% speed improvement here.
557
5584.01 Fri Oct 5 22:10:49 CEST 2007
559 - instead of recreating *a* standard output handle we simply
560 use STDOUT, which is faster and hopefully more robust.
561
5624.0 Fri Oct 5 12:56:00 CEST 2007
10 - incompatibly changed Coro::Storable::freeze. 563 - incompatibly changed Coro::Storable::freeze.
11 - major new feature: added Coro::Debug, for interactive coroutine 564 - major new feature: added Coro::Debug, for interactive coroutine
12 debugging, tracing and much more. 565 debugging, tracing and much more.
566 - major bug fix: unbelievable, but true: $_, $/ and many other
567 "saved" variables actually weren't being saved. This has been fixed,
568 of course, while increasing performance while losing all the save
569 flags.
570 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 571 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 572 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 573 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
574 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 575 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool 576 - better async_pool resource management, moved parts of async_pool
18 handling to XS (major speed improvement). 577 handling to XS (major speed improvement).
19 - actually croak before modifying important data structures. 578 - actually croak before modifying important data structures.
20 - refuse to transfer while compiling. 579 - refuse to transfer while compiling.
21 - possibly support eval EXPR better now. 580 - possibly support eval EXPR better now.
22 - enable assembly method per default on linux+bsd x86+amd64. 581 - enable assembly per default on linux+bsd x86+amd64.
582 - all internal members were renamed _something for easier subclassing.
23 - many minor tweaks. 583 - many minor tweaks.
