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
84.35 7 - croak when a coro being cancelled tries to block (e.g. while executing
8 a guard block).
9 - implement Coro->cancel in XS for a 20% speed improvement, and to
10 be able to implement mutual cancellation.
11 - cancelling a coro while it itself is cancelling another coro is
12 now supported and working, instead of triggering an assertion.
13 - be a bit more crash-resistant when calling (buggy) on_destroy
14 callbacks (best effort).
15
165.372 Wed Feb 23 06:14:30 CET 2011
17 - apparently mingw doesn't provide a working gettimeofday, try to
18 work around that by relying on Time::HiRes (indirectly brought to
19 my attention by Max Maischein).
20 - fix some portability issues when Time::HiRes was used.
21
225.371 Mon Feb 21 14:36:08 CET 2011
23 - backport to windows process emulation code again.
24
255.37 Sat Feb 19 07:49:44 CET 2011
26 - add a big "Coro thread life cycle" section to "man Coro".
27 - try a tentative workaround against the breakage that 5.13 has
28 introduced without depreciation period. sigh.
29 - no longer use Time::HiRes if gettimeofday is available, which
30 saves quite a lot of memory.
31
325.36 Sun Feb 13 05:33:41 CET 2011
33 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
34 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
35 method call.
36 - undocument Coro::Timer::sleep and obsolete whole module.
37 - optimise Coro::Timer::timeout memory and cpu usage.
38 - slightly updated Coro::Intro for recent changes.
39 - do not initialise PL_dirty anymore.
40
415.25 Thu Nov 11 01:08:39 CET 2010
42 - try a different approach on netbsd - netbsd 5 finally has marginally
43 working pthreads, but still broken ucontext/sigaltstack.
44 - openbsd 4.8 finally got their act together, Coro works out of the box
45 with asm, setjmp and pthreads (no change, just informational).
46
475.24 Sat Oct 23 11:27:12 CEST 2010
48 - port to the EV 4.0 API.
49 - work around bugs in mingw32, making strawberry perl work
50 out of the box.
51 - correctly modify Coro::AIO function prototypes
52 so that they reflect the "no optional parameters" rule.
53 - "ported" libcoro to C++.
54
555.23 Mon May 17 18:50:42 CEST 2010
56 - be more resistant to ordering changes when initialising
57 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
58 Waldorf).
59 - document that perl 5.12 deliberately removed support for cloning.
60
615.22 Wed Apr 14 03:55:35 CEST 2010
62 - correctly return udnef on errors in Coro::Handle::read/write
63 (testcase by Marc Mims).
64 - convert Coro::Util into a "perl compatibility wrapper" - the functions
65 are less useful now, but are drop-in replacements for existing
66 functions, listing better alternatives in the documentation. This also
67 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
68 with Coro::Util::inet_aton.
69 - do not override $Coro::idle unconditionally in Coro.pm, as other
70 modules could have provided their own idle coro already
71 (for exmaple, Coro::AnyEvent).
72 - fix Coro::Util::gethost* functions.
73 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
74
755.21 Wed Dec 16 07:19:51 CET 2009
76 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
77 together.
78 - add some examples on how to combine other event loops with Coro in
79 Coro::AnyEvent, and how to run it (and not to block). Seems to be
80 the most common source of confusion.
81 - try to catch people naively blocking in an event callback.
82 - work around the perl filehandle bug issue in conjunction with
83 older common::sense (as indirectly pointed out by ZSystem).
84 - clarify the "not from signal handlers" section.
85
865.2 Sun Oct 4 14:54:24 CEST 2009
87 - Coro::Storable destroyed the prototypes of the functions it wrapped.
88 - export rouse_cb and rouse_wait by default now.
89 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
90 - new method $state->swap_sv.
91 - added section on "windows process emulation" to the manpage,
92 after a not-so-fruitful (nor-friendly) "discussion" with chip
93 salzenberg (discussion implies arguments, but his only arguments
94 were ad-hominems, one wonders why he started it in the first
95 place). I hope this explains it well enough for him to understand,
96 and maybe well enough for others to understand.
97 - use common::sense everywhere now.
98 - idle callbacks are no longer supported, use idle coros instead.
99 - print a thread listing when a deadlock is detected.
100
1015.17 Sat Aug 22 23:09:31 CEST 2009
102 - work around a bug in the perl debugger causing crashes
103 when running under the debugger by marking _pool_handler as nodebug.
104 - speed up Coro::async considerably.
105 - try some hacks to get netbsd to work "more often" - their broken
106 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
107 - convert Coro to AE 5.0 API.
108
1095.162 Tue Jul 28 04:04:03 CEST 2009
110 - perl 5.8.2 is now minimum requirement.
111 - skip t/19_handle.t on broken windows perls.
112
1135.161 Wed Jul 22 04:47:38 CEST 2009
114 - Coro::AnyEvent::poll could have a different prototype when EV was
115 used as backend (analyzed by Tatsuhiko Miyagawa).
116 - Coro::AnyEvent errornously initialised the event loop when loaded,
117 not on demand.
118 - try to workaround rare */t/01_unblock.t failures.
119
1205.16 Tue Jul 21 01:44:37 CEST 2009
121 - Coro::AnyEvent failed to hook into the event loop
122 when no threads had been readied between detecting
123 the event loop and actually running it.
124 - considerably speed up Coro::Select by taking avdantage
125 of AnyEvent > 4.8 and some other optimisations.
126 - implement paragraph readline mode in Coro::Handle
127 (based on patches by Zsbán Ambrus).
128 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
129 and analyzed by Yasuhiro MATSUMOTO).
130 - clarified libcoro license and copyright.
131 - someone stole my EXTRA_META!!!
132 - implement Coro::Select::patch_pp_sselect and it's brother,
133 for hardcode select overriding.
134
1355.151 Mon Jul 6 05:41:57 CEST 2009
136 - backport to windows process emulation code again (patch by
137 Yasuhiro MATSUMOTO).
138 - slightly update Coro::MakeMaker.
139
1405.15 Tue Jun 30 10:28:06 CEST 2009
141 - deprecate Coro::Socket, document how to get ipv6 support via
142 AnyEvent::Socket instead.
143 - implement signal->wait ($cb) interface, similar to semaphores.
144 - work around SvOK not supporting getmagic, so we have to getmagic
145 to test for undef :/ (reported by Matthias Waldorf).
146 - load Coro::AnyEvent in all modules using AnyEvent.
147 - work around perl corrupting our internal data structures,
148 reported by Tokuhiro Matsuno.
149 - enable per-coroutine real and cpu time gathering
150 (Coro::State::enable_times).
151
1525.14 Wed Jun 24 01:37:48 CEST 2009
153 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
154 as this seems to have been a difficult concept (poll, sleep, idle,
155 idle_upto).
156 - add Coro::AnyEvent::readable/writable functions.
157 - clarify Coro::EV/Event/AnyEvent manpages.
158 - free per-thread global scalars in the thread calling ->cancel, to
159 avoid crashes when $_, $@ etc., are magical but some of those
160 had already been freed.
161 - "unexperimentalise" the callback interface for Coro::Semaphore.
162 - speed up ready queue management/context switching by using a linked
163 list instead of an array (~5-10%).
164 - implement "watch" command in Coro::Debug shells.
165 - for fun, implement time-slicing as an example in the manpage.
166 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
167 Coro::Event, use the normal AnyEvent handling instead of dieing
168 (the same is true for Coro::Handle).
169 - properly document Coro::EV::timed_io_once.
170 - avoid unneccessary ->cancel calls in Coro::Handle.
171 - maybe make it work on mingw32 with win32 backend
172 (based on patch by Yasuhiro Matsumoto).
173
1745.132 Fri May 29 09:00:39 CEST 2009
175 - do not keep a reference to the argument itself in
176 Coro::Semaphore::guard, as it could change later.
177 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
178 should support a prepare callback.
179
1805.131 Mon Mar 16 23:20:37 CET 2009
181 - implement and document Coro->suspend, Coro->resume.
182 - fix Coro::Select implementation to not (often) close
183 the passed file descriptors (testcase provided by pippijn).
184
1855.13 Mon Dec 15 21:51:42 CET 2008
186 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
187 - don't set diehook to C<undef> but instead to NULL, to avoid
188 spurious warnings.
189 - fix a lot of bugs in Coro::SemaphoreSet.
190 - Coro::SemaphoreSet will less often create a semaphore needlessly.
191 - add Coro::SemaphoreSet::count and wait methods.
192 - take advantage of the new Guard module.
193 - deprecate Coro::guard.
194 - try to fix the dreaded 01_unblock tests once more. I hate it when
195 testsuites need more fixing than the code they are supposed to test.
196 - croak in more cases when a required callback isn't resolvable.
197 - fix some minor issues in Coro::State->call/eval.
198 - use current coroutine context instead of a temporary one
199 when temporarily switching to another coroutine.
200 - do not call C-level on_destroy handlers during global destruction,
201 to avoid needless segfaults.
202
2035.12 Sun Dec 7 13:30:38 CET 2008
204 - add default config for MirOS, which seems to be a bug-to-bug
205 compatible fork of openbsd ("world domination by releasing
206 openbsd cvs before the openbsd folks do it" or so :).
207 - free_padlist did destroy the names pad, not good, but didn't
208 seem to bother perl - this could fix issues such as eval ""
209 inside a function called from multiple coroutines.
210 - use a different method to detect destruction time.
211 - be more careful when freeing padlists just before global
212 destruction.
213 - fixed and expanded the call/cc example.
214 - renamed _terminate to _coro_run.
215 - new method Coro::Channel->shutdown.
216 - try pthreads on openbsd <4.4 (broken sigaltstack, will
217 pthreads fare better?).
218 - be less picky about destroying "a" running coroutine.
219
2205.11 Tue Nov 25 21:49:05 CET 2008
221 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
222 working code with failed assertions, introducing more bugs than
223 it fixes, requiring elaborate workarounds :(
224
2255.1 Mon Nov 24 08:54:59 CET 2008
226 - wrote a small introductory tutorial - Coro::Intro.
227 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
228 - Coro::Select did errornously dup the file descriptors
229 and didn't work with all AnyEvent backends.
230 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
231 LWP data transfers.
232 - disassociate c contexts from coro objects - this is agruably more
233 correct, but mostly allows sharing of cctxs between coro and state
234 objects, for added memory savings and speed increases.
235 - bumped $Coro::POOL_RSS up to 32kb by default.
236 - no longer set the optype to OP_CUSTOM, as B::* understandably
237 doesn't like this very much (and we *are* a type of entersub).
238 - implement state cloning, just to prove that call/cc can be done.
239 - automatically load Coro::AnyEvent in Coro::Handle.
240 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
241 do not have this method (and don't need it either).
242 - speed up generic anyevent methods in Coro::Handle by using rouse
243 callbacks.
244 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
245 others. It also makes the debugger happier, as you can trace
246 through the idle threads now.
247 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
248 - eg/event was pretty broken.
249 - better 5.8.6 compatibility.
250
2515.0 Thu Nov 20 10:35:05 CET 2008
252 - NEW ARCHITECTURE: use the latest 4.x version if you experience
253 stability issues.
254 - bump API version to 7 - all dependents must be recompiled.
255 - removed timed_* functions - they were not being used anyways
256 and should be replaced by a more generic mechanism -
257 and were annoying to support anyways :)
258 - removed SemaphoreSet's waiter method - use sem method instead.
259 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
260 - async_pool did free a scalar value twice
261 ("Attempt to unreference...").
262 - fix a longstanding bug where calling terminate on a coro that
263 was waiting for a semaphore that was just becoming available
264 would cause a deadlock (semaphore would get into a state where
265 it was available but waiters were still blocked).
266 - calling throw on a coroutine that is waiting for a semaphore will
267 no longer make it acquire the semaphore (and thus leak a count).
268 - perl's process emulation is now not even theoretically supported
269 anymore.
270 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
271 conversion of callback-style to blocking-style.
272 - new methods $coro->schedule_to and ->cede_to, to specifically
273 schedule or cede to a specific coroutine.
274 - new function Coro::Semaphore::wait.
275 - use named constants in Coro::Channel (Richard Hundt).
276 - directly patch the entersub opcode calling SLF functions (cede,
277 transfer and so on). this does speed up context switching, but
278 more importanly, it frees us from the hardcoded behaviour of
279 entersub, so we might actually be able to return something from
280 those functions and atcually create new ones.
281 - take advantage of __builtin_frame_address on gcc.
282 - expose THX in coroapi (not sure whether this was a wise decision,
283 as "threaded" perls are running at half speed anyways).
284 - implement execute_slf (schedule-like-function) interface that makes
285 it possible to implement schedule-like-functions in XS.
286 - use new SLF interface to massively speed up Coro::EV by roughly a
287 factor of two.
288 - used new SLF interface to massively speed up Coro::Semaphore by a
289 factor of three.
290 - used new SLF interface to speed up Coro::AIO by roughly a factor of
291 four and reduce its memory usage considerably.
292 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
293 for a nice speedup and vastly more correct behaviour. Also implement
294 a new method "sem" to get at the underlying semaphore object.
295 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
296 (in comparison) 20-40% speedup.
297 - used new SLF interface to reimplement Coro::Signal gaining
298 some unknown (because I was too lazy), but certain, speedup, and also
299 making signals reliable for the first time.
300 - used new SLF interface and other optimisations to speed up async_pool
301 by a factor of two. It also doesn't rely on perl's exception mechanism
302 to exit anymore. The overhead for terminating an async_pool, coro over
303 a normal async is now very small.
304 - sped up coroutine creation/destruction by 40%.
305 - forgot to include Coro/libcoro/README in the dist for all these years.
306 - work around a freebsd pthreads bug (manual testcancel is required as
307 pthread_cond_wait isn't a cancellation point on freebsd).
308 - use new rouse functions to speed up and simplify Coro::BDB.
309 - make "prefer perl native functions" work with threaded perls.
310 - condense Coro::Debug ps output, hint at v and w flags.
311 - (libcoro) lots of minor cleanups and portability improvements.
312
3134.914 Wed Nov 19 12:54:18 CET 2008
314 - fix a disastrous bug in the readline optimisation
315 introduced in 4.801.
316
3174.913 Sat Nov 15 07:58:28 CET 2008
318 - async_pool did free a scalar value twice
319 ("Attempt to unreference...").
320
3214.912 Thu Nov 13 18:31:23 CET 2008
322 - minor cleanups.
323 - use much larger stacks on linux and perl < 5.8.8.
324 - Coro::Debug::new_unix_server did not unlink the socket
325 when destroyed.
326
3274.911 Tue Nov 11 04:26:17 CET 2008
328 - "port" to threaded perls.
329
3304.91 Mon Nov 10 05:36:38 CET 2008
331 - the ->throw exception object no longer leaks.
332 - creating a new cctx leaked a scopestack entry (memleak).
333 - new coroutines didn't get created with a zero flags field
334 (unknown impact).
335 - calling ->throw on a not-yet-started coroutine should now work
336 instead of being ignored.
337 - ->throw is now supported on Coro::State objects.
338 - clean up cctx creation code a bit.
339 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
340
3414.9 Sat Nov 8 17:45:27 CET 2008
342 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
343 - (libcoro) no longer leak threads in the experimental pthread backend,
344 also speed it up considerably.
345 - (libcoro) do not rely on makecontext passing void *'s unscathed.
346 - fix compiletime dependencies on libcoro in the Makefile.
347 - cctx_count wasn't always updated properly.
348 - Coro::State::cctx_stacksize wasn't applied correctly.
349 - new function Coro::State::cctx_max_idle.
350 - the default max number of idle C contexts is now 4.
351 - (libcoro) try harder to get _setjmp/_longjmp.
352 - (libcoro) cleanup and extend the libcoro API to officially
353 allow the creation of empty source contexts.
354 - very experimental workaround for the totally broken netbsd platform.
355 - tried to hack around openbsd bugs.
356
3574.804 Wed Nov 5 16:36:00 CET 2008
358 - Coro::Debug::new_unix_server would not create a non-blocking listening
359 socket, sometimes causing freezes.
360 - (libcoro) fix misaligned stack points for setjmp and assembly
361 methods, which can cause crashes on x86/x86_64 with a sufficiently
362 aggressive compiler.
363 - new function: Coro::Debug::new_tcp_server.
364 - move ->throw into the Coro class because it only works on coro objects.
365
3664.803 Mon Nov 3 17:16:12 CET 2008
367 - (libcoro) use a global asm statement to become independent of gcc
368 otpimisations for CORO_ASM (thanks to pippijn for the idea).
369 - try to workaround yet another broken bsd, this time dragonfly.
370
3714.802 Thu Oct 30 10:56:12 CET 2008
372 - support -fno-omit-frame-pointer on x86 with the assembly method.
373 - tune 01_unblock.t tests a bit.
374
3754.801 Wed Oct 22 18:33:37 CEST 2008
376 - improve readline speed for very long "lines".
377 - backport to 5.8.8.
378
3794.8 Thu Oct 2 13:34:40 CEST 2008
380 - new function Coro::AIO::aio_wait.
381 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
382 - greatly speed up and reduce memory usage of Coro::AIO requests.
383 - implement some other µ-optimisations.
384
3854.749 Mon Sep 29 14:40:12 CEST 2008
386 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
387
3884.748 Sat Sep 27 14:03:19 CEST 2008
389 - implement, but do not document, PerlIO::cede(granularity).
390 - Coro::Storable forgot to wrap Storable::pstore.
391 - work around the multitude of leaks and memory corruption
392 bugs in PerlIO::via by using our own C-level perliol. As a side
393 effect, Coro::Storable is now much, much, much faster.
394
3954.747 Tue Sep 23 01:59:41 CEST 2008
396 - fix a per-cv memleak (one empty array was leaked per
397 code reference).
398 - avoid a crash in coro->call|rss when the coroutine was already
399 destroyed (most noticably when using Coro::Debug::ps :)
400 - also protect *Storable::FILE.
401 - push up default storable granularity to 20ms.
402
4034.746 Sun Sep 21 03:22:20 CEST 2008
404 - be more insistent on locking Storable against reentrancy
405 in Coro::Storable.
406 - move swap_def?v and throw to Coro::State, as documented.
407
4084.745 Thu Jul 24 00:14:38 CEST 2008
409 - remove debugging code related to MgPV_nolen_const, also try to
410 make it compile with perl 5.8.6 (yes, apple apparently loves
411 outdated software). Reported by John S.
412
4134.744 Tue Jul 8 22:06:35 CEST 2008
414 - correctly provide default DIE/WARN handlers as documented.
415 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
416 implementations inside perl work fine for us.
417
4184.743 Mon Jun 16 00:21:57 CEST 2008
419 - when using Coro::EV without running EV::loop it could
420 result in busy-waiting for events, this has been fixed.
421 - reduce codesize and improve performance by using EV_DEFAULT_UC.
422
4234.742 Sat May 31 14:10:21 CEST 2008
424 - implement a workaround for (some) perl <5.8.8 versions.
425 - require EV 3.3+.
426
4274.741 Fri May 30 23:33:09 CEST 2008
428 - tell netbsd how utterly broken their imitation of an OS is
429 and refuse to build by default if pthreads are in use.
430 - switch to "s" method on all bsd's by default, as their ucontext
431 stuff seems just too broken.
432 - fix a bug in Coro::Select.
433
4344.74 Thu May 29 20:05:31 CEST 2008
435 - do not test Coro::LWP for lack of dependencies.
436 - do not test Coro::Select for lack of working perls.
437
4384.73 Thu May 29 2008
439 - fix a bug in Coro::EV which would cause it to block despite
440 there being runnable coroutines.
441 - sprinkle "no warnings" freely over everything, also suppress
442 warnings for some other modules.
443 - fix typo in WSAEWOULDBLOCK.
444
4454.72 Sun May 25 05:14:36 CEST 2008
446 - tweak META.yaml a bit, unfortunately, there is no documented way
447 to have optional dependencies with CPAN. doh :(
448 - avoid running some tests on windows because they would fail due to
449 perl bug (broken fork, broken pipes...).
450 - work around perl on windows bugs where perl returns undocumented
451 error codes for sysread, syswrite etc. by taking advantage
452 of AnyEvent's workaround for that problem.
453 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
454 a common perl implementation bug on windows.
455 - use unix domain sockets in testsuite to work around
456 common perl implementation bugs on widows (they are emulated by
457 tcp sockets on windows. ugh.)
458
4594.71 Sat May 24 20:01:27 CEST 2008
460 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
461 - take advantage of async name resolution of AnyEvent::Util.
462 - work around brutal inet_aton override in Coro::LWP.
463 - take advantage of the readyhook in Coro::EV, for smoother
464 scheduling.
465
4664.7 Sun May 11 00:32:19 CEST 2008
467 - completely reworked the Coro manpage.
468 - added Coro::AnyEvent, generic event loop integration.
469 - implement cancel, ready and kill commands in Coro::Debug.
470 - document find_coro in Coro::Debug.
471 - incompatible change: rename has_stack to has_cctx.
472 - Coro::AIO and Coro::BDB no longer force event model detection,
473 use AnyEvent::AIO and AnyEvent::BDB.
474
4754.6 Sat Apr 26 10:05:14 CEST 2008
476 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
477 by the Coro module. It was a mistake to have it in the first place.
478 - (experimental) support for activestate perl 5.10 (method "w").
479 - (experimental) support for strawberry perl (method "a").
480 - coro_sigelem_set did not return a value although it had to,
481 actual impact unknown.
482
4834.51 Mon Apr 14 13:28:27 CEST 2008
484 - make it compile again on 5.8.
485
4864.50 Thu Apr 10 09:43:17 CEST 2008
487 - I did it twice! (see 4.49).
488
4894.49 Sun Apr 6 21:23:31 CEST 2008
490 - grr, instead of compiling the recent changes on 5.10 only they
491 were compiled on 5.8 only.
492
4934.48 Sun Apr 6 20:36:46 CEST 2008
494 - allow coroutine switches during eval's under 5.10.x, as it seems
495 the parser is a per-interpreter option now, so this is safe
496 (this might fix the odd crashing bug).
497 - drop support for 5.9.x versions: they are dead, jim.
498
4994.47 Sun Apr 6 00:37:52 CEST 2008
500 - force cctx allocation on API calls: we know we need to force one
501 and gcc actually manages to confuse our heuristic nowadays,
502 leading to crashes and worse.
503 - document force_cctx.
504
5054.46 Fri Apr 4 22:05:43 CEST 2008
506 - upgrade libcoro, resulting in pthread-backend (which was only created
507 to fulfill the rules of the programming languages shootout).
508
5094.45 Thu Mar 13 11:55:36 CET 2008
510 - fix a file leaking bug in eg/mhyttpd that would allow
511 downloading of any file (reported by oesi).
512 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
513 (also add testcase).
514 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
515 apparently having loads of fun with that).
516 - implement $state->swap_defsv, ->swap_defav and document ->throw.
517
5184.4 Wed Feb 13 16:44:29 CET 2008
519 - only assume .cfi pseudo isns exist on GNU/Linux.
520 - add get_timed method to Coro::Channels.
521 - fixed Coro::Debug manpage.
522 - perl 5.11 compatbility improvement based on patch by
523 Andreas König.
524
5254.37 Sun Jan 20 11:25:23 CET 2008
526 - soften the check for an active parser for perl 5.10 (avoiding
527 "Coro::State::transfer called while parsing" in many cases).
528
5294.36 Sun Jan 13 10:53:56 CET 2008
530 - reset diehook when terminating from an async_pool as to not
531 trigger any __DIE__ handlers.
532
5334.35 Sun Jan 13 04:14:13 CET 2008
9 - "bt" debug command now displays any exceptions 534 - "bt" debug command now displays any exceptions
10 from longmess and also skips the innermost 535 from longmess and also skips the innermost
11 stackframes, giving more useufl output. 536 stackframes, giving more useufl output.
12 - allow backtraces in coroutines blocked in Coro::EV, 537 - allow backtraces in coroutines blocked in Coro::EV,
13 at a <1% speed hit. 538 at a <1% speed hit.
14 - handle localising of $SIG{__WARN__} and __DIE__ 539 - handle localising of $SIG{__WARN__} and __DIE__
15 properly (with a proepr amount of dirty hacking). 540 properly (with a proper amount of dirty hacking).

174.34 Sat Dec 22 17:49:53 CET 2007 5424.34 Sat Dec 22 17:49:53 CET 2007
18 - upgrade to EV version 2.0 API. 543 - upgrade to EV version 2.0 API.
