93.8 11 - added section on "windows process emulation" to the manpage,
12 after a not-so-fruitful (nor-friendly) "discussion" with chip
13 salzenberg (discussion implies arguments, but his only arguments
14 were ad-hominems, one wonders why he started it in the first
15 place). I hope this explains it well enough for him to understand,
16 and maybe well enough for others to understand.
17
185.17 Sat Aug 22 23:09:31 CEST 2009
19 - work around a bug in the perl debugger causing crashes
20 when running under the debugger by marking _pool_handler as nodebug.
21 - speed up Coro::async considerably.
22 - try some hacks to get netbsd to work "more often" - their broken
23 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
24 - convert Coro to AE 5.0 API.
25
265.162 Tue Jul 28 04:04:03 CEST 2009
27 - perl 5.8.2 is now minimum requirement.
28 - skip t/19_handle.t on broken windows perls.
29
305.161 Wed Jul 22 04:47:38 CEST 2009
31 - Coro::AnyEvent::poll could have a different prototype when EV was
32 used as backend (analyzed by Tatsuhiko Miyagawa).
33 - Coro::AnyEvent errornously initialised the event loop when loaded,
34 not on demand.
35 - try to workaround rare */t/01_unblock.t failures.
36
375.16 Tue Jul 21 01:44:37 CEST 2009
38 - Coro::AnyEvent failed to hook into the event loop
39 when no threads had been readied between detecting
40 the event loop and actually running it.
41 - considerably speed up Coro::Select by taking avdantage
42 of AnyEvent > 4.8 and some other optimisations.
43 - implement paragraph readline mode in Coro::Handle
44 (based on patches by Zsbán Ambrus).
45 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
46 and analyzed by Yasuhiro MATSUMOTO).
47 - clarified libcoro license and copyright.
48 - someone stole my EXTRA_META!!!
49 - implement Coro::Select::patch_pp_sselect and it's brother,
50 for hardcode select overriding.
51
525.151 Mon Jul 6 05:41:57 CEST 2009
53 - backport to windows process emulation code again (patch by
54 Yasuhiro MATSUMOTO).
55 - slightly update Coro::MakeMaker.
56
575.15 Tue Jun 30 10:28:06 CEST 2009
58 - deprecate Coro::Socket, document how to get ipv6 support via
59 AnyEvent::Socket instead.
60 - implement signal->wait ($cb) interface, similar to semaphores.
61 - work around SvOK not supporting getmagic, so we have to getmagic
62 to test for undef :/ (reported by Matthias Waldorf).
63 - load Coro::AnyEvent in all modules using AnyEvent.
64 - work around perl corrupting our internal data structures,
65 reported by Tokuhiro Matsuno.
66 - enable per-coroutine real and cpu time gathering
67 (Coro::State::enable_times).
68
695.14 Wed Jun 24 01:37:48 CEST 2009
70 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
71 as this seems to have been a difficult concept (poll, sleep, idle,
72 idle_upto).
73 - add Coro::AnyEvent::readable/writable functions.
74 - clarify Coro::EV/Event/AnyEvent manpages.
75 - free per-thread global scalars in the thread calling ->cancel, to
76 avoid crashes when $_, $@ etc., are magical but some of those
77 had already been freed.
78 - "unexperimentalise" the callback interface for Coro::Semaphore.
79 - speed up ready queue management/context switching by using a linked
80 list instead of an array (~5-10%).
81 - implement "watch" command in Coro::Debug shells.
82 - for fun, implement time-slicing as an example in the manpage.
83 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
84 Coro::Event, use the normal AnyEvent handling instead of dieing
85 (the same is true for Coro::Handle).
86 - properly document Coro::EV::timed_io_once.
87 - avoid unneccessary ->cancel calls in Coro::Handle.
88 - maybe make it work on mingw32 with win32 backend
89 (based on patch by Yasuhiro Matsumoto).
90
915.132 Fri May 29 09:00:39 CEST 2009
92 - do not keep a reference to the argument itself in
93 Coro::Semaphore::guard, as it could change later.
94 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
95 should support a prepare callback.
96
975.131 Mon Mar 16 23:20:37 CET 2009
98 - implement and document Coro->suspend, Coro->resume.
99 - fix Coro::Select implementation to not (often) close
100 the passed file descriptors (testcase provided by pippijn).
101
1025.13 Mon Dec 15 21:51:42 CET 2008
103 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
104 - don't set diehook to C<undef> but instead to NULL, to avoid
105 spurious warnings.
106 - fix a lot of bugs in Coro::SemaphoreSet.
107 - Coro::SemaphoreSet will less often create a semaphore needlessly.
108 - add Coro::SemaphoreSet::count and wait methods.
109 - take advantage of the new Guard module.
110 - deprecate Coro::guard.
111 - try to fix the dreaded 01_unblock tests once more. I hate it when
112 testsuites need more fixing than the code they are supposed to test.
113 - croak in more cases when a required callback isn't resolvable.
114 - fix some minor issues in Coro::State->call/eval.
115 - use current coroutine context instead of a temporary one
116 when temporarily switching to another coroutine.
117 - do not call C-level on_destroy handlers during global destruction,
118 to avoid needless segfaults.
119
1205.12 Sun Dec 7 13:30:38 CET 2008
121 - add default config for MirOS, which seems to be a bug-to-bug
122 compatible fork of openbsd ("world domination by releasing
123 openbsd cvs before the openbsd folks do it" or so :).
124 - free_padlist did destroy the names pad, not good, but didn't
125 seem to bother perl - this could fix issues such as eval ""
126 inside a function called from multiple coroutines.
127 - use a different method to detect destruction time.
128 - be more careful when freeing padlists just before global
129 destruction.
130 - fixed and expanded the call/cc example.
131 - renamed _terminate to _coro_run.
132 - new method Coro::Channel->shutdown.
133 - try pthreads on openbsd <4.4 (broken sigaltstack, will
134 pthreads fare better?).
135 - be less picky about destroying "a" running coroutine.
136
1375.11 Tue Nov 25 21:49:05 CET 2008
138 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
139 working code with failed assertions, introducing more bugs than
140 it fixes, requiring elaborate workarounds :(
141
1425.1 Mon Nov 24 08:54:59 CET 2008
143 - wrote a small introductory tutorial - Coro::Intro.
144 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
145 - Coro::Select did errornously dup the file descriptors
146 and didn't work with all AnyEvent backends.
147 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
148 LWP data transfers.
149 - disassociate c contexts from coro objects - this is agruably more
150 correct, but mostly allows sharing of cctxs between coro and state
151 objects, for added memory savings and speed increases.
152 - bumped $Coro::POOL_RSS up to 32kb by default.
153 - no longer set the optype to OP_CUSTOM, as B::* understandably
154 doesn't like this very much (and we *are* a type of entersub).
155 - implement state cloning, just to prove that call/cc can be done.
156 - automatically load Coro::AnyEvent in Coro::Handle.
157 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
158 do not have this method (and don't need it either).
159 - speed up generic anyevent methods in Coro::Handle by using rouse
160 callbacks.
161 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
162 others. It also makes the debugger happier, as you can trace
163 through the idle threads now.
164 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
165 - eg/event was pretty broken.
166 - better 5.8.6 compatibility.
167
1685.0 Thu Nov 20 10:35:05 CET 2008
169 - NEW ARCHITECTURE: use the latest 4.x version if you experience
170 stability issues.
171 - bump API version to 7 - all dependents must be recompiled.
172 - removed timed_* functions - they were not being used anyways
173 and should be replaced by a more generic mechanism -
174 and were annoying to support anyways :)
175 - removed SemaphoreSet's waiter method - use sem method instead.
176 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
177 - async_pool did free a scalar value twice
178 ("Attempt to unreference...").
179 - fix a longstanding bug where calling terminate on a coro that
180 was waiting for a semaphore that was just becoming available
181 would cause a deadlock (semaphore would get into a state where
182 it was available but waiters were still blocked).
183 - calling throw on a coroutine that is waiting for a semaphore will
184 no longer make it acquire the semaphore (and thus leak a count).
185 - perl's process emulation is now not even theoretically supported
186 anymore.
187 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
188 conversion of callback-style to blocking-style.
189 - new methods $coro->schedule_to and ->cede_to, to specifically
190 schedule or cede to a specific coroutine.
191 - new function Coro::Semaphore::wait.
192 - use named constants in Coro::Channel (Richard Hundt).
193 - directly patch the entersub opcode calling SLF functions (cede,
194 transfer and so on). this does speed up context switching, but
195 more importanly, it frees us from the hardcoded behaviour of
196 entersub, so we might actually be able to return something from
197 those functions and atcually create new ones.
198 - take advantage of __builtin_frame_address on gcc.
199 - expose THX in coroapi (not sure whether this was a wise decision,
200 as "threaded" perls are running at half speed anyways).
201 - implement execute_slf (schedule-like-function) interface that makes
202 it possible to implement schedule-like-functions in XS.
203 - use new SLF interface to massively speed up Coro::EV by roughly a
204 factor of two.
205 - used new SLF interface to massively speed up Coro::Semaphore by a
206 factor of three.
207 - used new SLF interface to speed up Coro::AIO by roughly a factor of
208 four and reduce its memory usage considerably.
209 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
210 for a nice speedup and vastly more correct behaviour. Also implement
211 a new method "sem" to get at the underlying semaphore object.
212 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
213 (in comparison) 20-40% speedup.
214 - used new SLF interface to reimplement Coro::Signal gaining
215 some unknown (because I was too lazy), but certain, speedup, and also
216 making signals reliable for the first time.
217 - used new SLF interface and other optimisations to speed up async_pool
218 by a factor of two. It also doesn't rely on perl's exception mechanism
219 to exit anymore. The overhead for terminating an async_pool, coro over
220 a normal async is now very small.
221 - sped up coroutine creation/destruction by 40%.
222 - forgot to include Coro/libcoro/README in the dist for all these years.
223 - work around a freebsd pthreads bug (manual testcancel is required as
224 pthread_cond_wait isn't a cancellation point on freebsd).
225 - use new rouse functions to speed up and simplify Coro::BDB.
226 - make "prefer perl native functions" work with threaded perls.
227 - condense Coro::Debug ps output, hint at v and w flags.
228 - (libcoro) lots of minor cleanups and portability improvements.
229
2304.914 Wed Nov 19 12:54:18 CET 2008
231 - fix a disastrous bug in the readline optimisation
232 introduced in 4.801.
233
2344.913 Sat Nov 15 07:58:28 CET 2008
235 - async_pool did free a scalar value twice
236 ("Attempt to unreference...").
237
2384.912 Thu Nov 13 18:31:23 CET 2008
239 - minor cleanups.
240 - use much larger stacks on linux and perl < 5.8.8.
241 - Coro::Debug::new_unix_server did not unlink the socket
242 when destroyed.
243
2444.911 Tue Nov 11 04:26:17 CET 2008
245 - "port" to threaded perls.
246
2474.91 Mon Nov 10 05:36:38 CET 2008
248 - the ->throw exception object no longer leaks.
249 - creating a new cctx leaked a scopestack entry (memleak).
250 - new coroutines didn't get created with a zero flags field
251 (unknown impact).
252 - calling ->throw on a not-yet-started coroutine should now work
253 instead of being ignored.
254 - ->throw is now supported on Coro::State objects.
255 - clean up cctx creation code a bit.
256 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
257
2584.9 Sat Nov 8 17:45:27 CET 2008
259 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
260 - (libcoro) no longer leak threads in the experimental pthread backend,
261 also speed it up considerably.
262 - (libcoro) do not rely on makecontext passing void *'s unscathed.
263 - fix compiletime dependencies on libcoro in the Makefile.
264 - cctx_count wasn't always updated properly.
265 - Coro::State::cctx_stacksize wasn't applied correctly.
266 - new function Coro::State::cctx_max_idle.
267 - the default max number of idle C contexts is now 4.
268 - (libcoro) try harder to get _setjmp/_longjmp.
269 - (libcoro) cleanup and extend the libcoro API to officially
270 allow the creation of empty source contexts.
271 - very experimental workaround for the totally broken netbsd platform.
272 - tried to hack around openbsd bugs.
273
2744.804 Wed Nov 5 16:36:00 CET 2008
275 - Coro::Debug::new_unix_server would not create a non-blocking listening
276 socket, sometimes causing freezes.
277 - (libcoro) fix misaligned stack points for setjmp and assembly
278 methods, which can cause crashes on x86/x86_64 with a sufficiently
279 aggressive compiler.
280 - new function: Coro::Debug::new_tcp_server.
281 - move ->throw into the Coro class because it only works on coro objects.
282
2834.803 Mon Nov 3 17:16:12 CET 2008
284 - (libcoro) use a global asm statement to become independent of gcc
285 otpimisations for CORO_ASM (thanks to pippijn for the idea).
286 - try to workaround yet another broken bsd, this time dragonfly.
287
2884.802 Thu Oct 30 10:56:12 CET 2008
289 - support -fno-omit-frame-pointer on x86 with the assembly method.
290 - tune 01_unblock.t tests a bit.
291
2924.801 Wed Oct 22 18:33:37 CEST 2008
293 - improve readline speed for very long "lines".
294 - backport to 5.8.8.
295
2964.8 Thu Oct 2 13:34:40 CEST 2008
297 - new function Coro::AIO::aio_wait.
298 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
299 - greatly speed up and reduce memory usage of Coro::AIO requests.
300 - implement some other µ-optimisations.
301
3024.749 Mon Sep 29 14:40:12 CEST 2008
303 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
304
3054.748 Sat Sep 27 14:03:19 CEST 2008
306 - implement, but do not document, PerlIO::cede(granularity).
307 - Coro::Storable forgot to wrap Storable::pstore.
308 - work around the multitude of leaks and memory corruption
309 bugs in PerlIO::via by using our own C-level perliol. As a side
310 effect, Coro::Storable is now much, much, much faster.
311
3124.747 Tue Sep 23 01:59:41 CEST 2008
313 - fix a per-cv memleak (one empty array was leaked per
314 code reference).
315 - avoid a crash in coro->call|rss when the coroutine was already
316 destroyed (most noticably when using Coro::Debug::ps :)
317 - also protect *Storable::FILE.
318 - push up default storable granularity to 20ms.
319
3204.746 Sun Sep 21 03:22:20 CEST 2008
321 - be more insistent on locking Storable against reentrancy
322 in Coro::Storable.
323 - move swap_def?v and throw to Coro::State, as documented.
324
3254.745 Thu Jul 24 00:14:38 CEST 2008
326 - remove debugging code related to MgPV_nolen_const, also try to
327 make it compile with perl 5.8.6 (yes, apple apparently loves
328 outdated software). Reported by John S.
329
3304.744 Tue Jul 8 22:06:35 CEST 2008
331 - correctly provide default DIE/WARN handlers as documented.
332 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
333 implementations inside perl work fine for us.
334
3354.743 Mon Jun 16 00:21:57 CEST 2008
336 - when using Coro::EV without running EV::loop it could
337 result in busy-waiting for events, this has been fixed.
338 - reduce codesize and improve performance by using EV_DEFAULT_UC.
339
3404.742 Sat May 31 14:10:21 CEST 2008
341 - implement a workaround for (some) perl <5.8.8 versions.
342 - require EV 3.3+.
343
3444.741 Fri May 30 23:33:09 CEST 2008
345 - tell netbsd how utterly broken their imitation of an OS is
346 and refuse to build by default if pthreads are in use.
347 - switch to "s" method on all bsd's by default, as their ucontext
348 stuff seems just too broken.
349 - fix a bug in Coro::Select.
350
3514.74 Thu May 29 20:05:31 CEST 2008
352 - do not test Coro::LWP for lack of dependencies.
353 - do not test Coro::Select for lack of working perls.
354
3554.73 Thu May 29 2008
356 - fix a bug in Coro::EV which would cause it to block despite
357 there being runnable coroutines.
358 - sprinkle "no warnings" freely over everything, also suppress
359 warnings for some other modules.
360 - fix typo in WSAEWOULDBLOCK.
361
3624.72 Sun May 25 05:14:36 CEST 2008
363 - tweak META.yaml a bit, unfortunately, there is no documented way
364 to have optional dependencies with CPAN. doh :(
365 - avoid running some tests on windows because they would fail due to
366 perl bug (broken fork, broken pipes...).
367 - work around perl on windows bugs where perl returns undocumented
368 error codes for sysread, syswrite etc. by taking advantage
369 of AnyEvent's workaround for that problem.
370 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
371 a common perl implementation bug on windows.
372 - use unix domain sockets in testsuite to work around
373 common perl implementation bugs on widows (they are emulated by
374 tcp sockets on windows. ugh.)
375
3764.71 Sat May 24 20:01:27 CEST 2008
377 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
378 - take advantage of async name resolution of AnyEvent::Util.
379 - work around brutal inet_aton override in Coro::LWP.
380 - take advantage of the readyhook in Coro::EV, for smoother
381 scheduling.
382
3834.7 Sun May 11 00:32:19 CEST 2008
384 - completely reworked the Coro manpage.
385 - added Coro::AnyEvent, generic event loop integration.
386 - implement cancel, ready and kill commands in Coro::Debug.
387 - document find_coro in Coro::Debug.
388 - incompatible change: rename has_stack to has_cctx.
389 - Coro::AIO and Coro::BDB no longer force event model detection,
390 use AnyEvent::AIO and AnyEvent::BDB.
391
3924.6 Sat Apr 26 10:05:14 CEST 2008
393 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
394 by the Coro module. It was a mistake to have it in the first place.
395 - (experimental) support for activestate perl 5.10 (method "w").
396 - (experimental) support for strawberry perl (method "a").
397 - coro_sigelem_set did not return a value although it had to,
398 actual impact unknown.
399
4004.51 Mon Apr 14 13:28:27 CEST 2008
401 - make it compile again on 5.8.
402
4034.50 Thu Apr 10 09:43:17 CEST 2008
404 - I did it twice! (see 4.49).
405
4064.49 Sun Apr 6 21:23:31 CEST 2008
407 - grr, instead of compiling the recent changes on 5.10 only they
408 were compiled on 5.8 only.
409
4104.48 Sun Apr 6 20:36:46 CEST 2008
411 - allow coroutine switches during eval's under 5.10.x, as it seems
412 the parser is a per-interpreter option now, so this is safe
413 (this might fix the odd crashing bug).
414 - drop support for 5.9.x versions: they are dead, jim.
415
4164.47 Sun Apr 6 00:37:52 CEST 2008
417 - force cctx allocation on API calls: we know we need to force one
418 and gcc actually manages to confuse our heuristic nowadays,
419 leading to crashes and worse.
420 - document force_cctx.
421
4224.46 Fri Apr 4 22:05:43 CEST 2008
423 - upgrade libcoro, resulting in pthread-backend (which was only created
424 to fulfill the rules of the programming languages shootout).
425
4264.45 Thu Mar 13 11:55:36 CET 2008
427 - fix a file leaking bug in eg/mhyttpd that would allow
428 downloading of any file (reported by oesi).
429 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
430 (also add testcase).
431 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
432 apparently having loads of fun with that).
433 - implement $state->swap_defsv, ->swap_defav and document ->throw.
434
4354.4 Wed Feb 13 16:44:29 CET 2008
436 - only assume .cfi pseudo isns exist on GNU/Linux.
437 - add get_timed method to Coro::Channels.
438 - fixed Coro::Debug manpage.
439 - perl 5.11 compatbility improvement based on patch by
440 Andreas König.
441
4424.37 Sun Jan 20 11:25:23 CET 2008
443 - soften the check for an active parser for perl 5.10 (avoiding
444 "Coro::State::transfer called while parsing" in many cases).
445
4464.36 Sun Jan 13 10:53:56 CET 2008
447 - reset diehook when terminating from an async_pool as to not
448 trigger any __DIE__ handlers.
449
4504.35 Sun Jan 13 04:14:13 CET 2008
451 - "bt" debug command now displays any exceptions
452 from longmess and also skips the innermost
453 stackframes, giving more useufl output.
454 - allow backtraces in coroutines blocked in Coro::EV,
455 at a <1% speed hit.
456 - handle localising of $SIG{__WARN__} and __DIE__
457 properly (with a proper amount of dirty hacking).
458
4594.34 Sat Dec 22 17:49:53 CET 2007
460 - upgrade to EV version 2.0 API.
461
4624.33 Mon Dec 17 08:36:12 CET 2007
463 - make Coro::AIO etc. loadable in the absence of EV.
464
4654.32 Mon Dec 17 07:46:02 CET 2007
466 - majorly improved Coro::Handle's performance with Coro::EV.
467 - implemented the until now mythical Coro::BDB module.
468 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
469
4704.31 Wed Dec 5 12:32:39 CET 2007
471 - remove warn statement form Coro::Util.
472
4734.3 Tue Dec 4 20:33:14 CET 2007
474 - calls to the idle function could cause stack corruption
475 when the stack changed.
476 - do no longer rely on the presence of EV::DNS if EV is used
477 (because it is gone), but instead take avdantage of EV::ADNS
478 if available.
479 - add ($) prototypes to all functions in Coro::Storable.
480 - use a conventional (safer) idle callback in Coro::EV.
481 - do accept quickly in Coro::Debug to avoid endless loops.
482
4834.22 Fri Nov 30 16:04:04 CET 2007
484 - really use optimised versions for Event and EV in Coro::Util
485 and Coro::Handle.
486
4874.21 Sun Nov 25 10:48:59 CET 2007
488 - fix a spurious memory read.
489 - Coro::EV no longer keeps the eventloop "alive".
490
4914.2 Fri Nov 9 20:47:05 CET 2007
492 - enable/disable tracing from a new coroutine, not a pooled one.
493 - fix a memleak in Coro::Event.
494 - removed killall call from fork_eval.
495 - made sure store_fd is already loaded so that fork_eval
496 does not have to parse autoload in each subprocess.
497 - only use assembly method if -O switch is in $Config{optimize}.
498 - add (optional) Coro::EV module, so far the best event loop module
499 directly supported by Coro.
500 - if the event model is EV, use EV::DNS to resolve
501 stuff in Coro::Util.
502 - don't get confused by multiple event notifications in Coro::Handle.
503 - initial support for EV (libevent interface).
504 - require Event and EV using configure_requires, to force their existance.
505
5064.13 Wed Oct 24 07:26:45 CEST 2007
507 - add Coro::Storable::blocking_thaw.
508 - use a vastly more complicated technique to localise
509 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
510 - use a coroutine for the idle callback Coro::Event,
511 instead of running Event in the current coroutine context.
512 This also catches recursive invocations.
513 - actually report fork errors in gethostbyname and inet_aton.
514
5154.11 Thu Oct 11 02:40:24 CEST 2007
516 - port to threaded perls.
517
5184.1 Thu Oct 11 02:38:16 CEST 2007
519 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
520 be local to each coro (see Coro::State).
521 - incompatible change: for very deep reasons, cede and cede_notself
522 cannot return anything, so nothing will be returned.
523 - possibly bring back 5.10 compatibility (untested).
524 - work around stupid (and wrong) warning on 5.10 :(.
525 - overlay the saved state over the context stack. This saves
526 a few hundred bytes per coroutine on average and also
527 speeds up context switching a bit.
528 - further tune default stack sizes.
529 - (more) correctly calculate stack usage in coro_rss.
530 - Coro::Storable::blocking_* did not properly lock
531 resulting in races between coroutines.
532 - added Coro::Storable::guard.
533 - stopping to trace a coroutine could destroy the cctx of
534 an unrelated coroutine.
535 - explain the relationship between Perl and C coroutines in
536 more detail in Coro::State.
537 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
538 causing a fork per resolve. This also affected Coro::Socket.
539 - switch to a separate stack in $coro->call/eval to avoid
540 invalidating pointers.
541
5424.03 Sat Oct 6 21:24:00 CEST 2007
543 - added Coro::throw method.
544 - minor code cleanups.
545
5464.02 Sat Oct 6 02:36:47 CEST 2007
547 - fix a very minor per-coroutine memleak (a single codereference).
548 - fixed a bug where the currently in-use c context would be freed
549 prematurely (can happen only when programs change the stacksize
550 or use tracing).
551 - tracing can no longer keep a coro alive after it terminated.
552 - do static branch prediction in the common path for gcc. gives
553 about 2-5% speed improvement here.
554
5554.01 Fri Oct 5 22:10:49 CEST 2007
556 - instead of recreating *a* standard output handle we simply
557 use STDOUT, which is faster and hopefully more robust.
558
5594.0 Fri Oct 5 12:56:00 CEST 2007
10 - incompatibly changed Coro::Storable::freeze. 560 - incompatibly changed Coro::Storable::freeze.
11 - major new feature: added Coro::Debug, for interactive coroutine 561 - major new feature: added Coro::Debug, for interactive coroutine
12 debugging, tracing and much more. 562 debugging, tracing and much more.
563 - major bug fix: unbelievable, but true: $_, $/ and many other
564 "saved" variables actually weren't being saved. This has been fixed,
565 of course, while increasing performance while losing all the save
566 flags.
567 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 568 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 569 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 570 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
571 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 572 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool 573 - better async_pool resource management, moved parts of async_pool
18 handling to XS (major speed improvement). 574 handling to XS (major speed improvement).
19 - actually croak before modifying important data structures. 575 - actually croak before modifying important data structures.
20 - refuse to transfer while compiling. 576 - refuse to transfer while compiling.
21 - possibly support eval EXPR better now. 577 - possibly support eval EXPR better now.
22 - enable assembly method per default on linux+bsd x86+amd64. 578 - enable assembly per default on linux+bsd x86+amd64.
579 - all internal members were renamed _something for easier subclassing.
23 - many minor tweaks. 580 - many minor tweaks.
