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
7 - croak when a coro that is being cancelled tries to block
8 (e.g. while executing a guard block), instead of crashing or
9 deadlocking.
10 - implement a Coro->safe_cancel method that might fail, but
11 cancels in a "safer" way if it succeeds.
12 - implement Coro->cancel in XS for a 20% speed improvement, and to
13 be able to implement mutual cancellation.
14 - speed up context switches by a percent or two by more efficiently
15 allocating context stack entries.
16 - cancelling a coro while it itself is cancelling another coro is
17 now supported and working, instead of triggering an assertion.
18 - be a bit more crash-resistant when calling (buggy) on_destroy
19 callbacks (best effort).
20 - move on_destroy into the slf_frame, to allow extension slf
21 functions to have destructors.
22
235.372 Wed Feb 23 06:14:30 CET 2011
24 - apparently mingw doesn't provide a working gettimeofday, try to
25 work around that by relying on Time::HiRes (indirectly brought to
26 my attention by Max Maischein).
27 - fix some portability issues when Time::HiRes was used.
28
295.371 Mon Feb 21 14:36:08 CET 2011
30 - backport to windows process emulation code again.
31
325.37 Sat Feb 19 07:49:44 CET 2011
33 - add a big "Coro thread life cycle" section to "man Coro".
34 - try a tentative workaround against the breakage that 5.13 has
35 introduced without depreciation period. sigh.
36 - no longer use Time::HiRes if gettimeofday is available, which
37 saves quite a lot of memory.
38
395.36 Sun Feb 13 05:33:41 CET 2011
40 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
41 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
42 method call.
43 - undocument Coro::Timer::sleep and obsolete whole module.
44 - optimise Coro::Timer::timeout memory and cpu usage.
45 - slightly updated Coro::Intro for recent changes.
46 - do not initialise PL_dirty anymore.
47
485.25 Thu Nov 11 01:08:39 CET 2010
49 - try a different approach on netbsd - netbsd 5 finally has marginally
50 working pthreads, but still broken ucontext/sigaltstack.
51 - openbsd 4.8 finally got their act together, Coro works out of the box
52 with asm, setjmp and pthreads (no change, just informational).
53
545.24 Sat Oct 23 11:27:12 CEST 2010
55 - port to the EV 4.0 API.
56 - work around bugs in mingw32, making strawberry perl work
57 out of the box.
58 - correctly modify Coro::AIO function prototypes
59 so that they reflect the "no optional parameters" rule.
60 - "ported" libcoro to C++.
61
625.23 Mon May 17 18:50:42 CEST 2010
63 - be more resistant to ordering changes when initialising
64 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
65 Waldorf).
66 - document that perl 5.12 deliberately removed support for cloning.
67
685.22 Wed Apr 14 03:55:35 CEST 2010
69 - correctly return udnef on errors in Coro::Handle::read/write
70 (testcase by Marc Mims).
71 - convert Coro::Util into a "perl compatibility wrapper" - the functions
72 are less useful now, but are drop-in replacements for existing
73 functions, listing better alternatives in the documentation. This also
74 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
75 with Coro::Util::inet_aton.
76 - do not override $Coro::idle unconditionally in Coro.pm, as other
77 modules could have provided their own idle coro already
78 (for exmaple, Coro::AnyEvent).
79 - fix Coro::Util::gethost* functions.
80 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
81
825.21 Wed Dec 16 07:19:51 CET 2009
83 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
84 together.
85 - add some examples on how to combine other event loops with Coro in
86 Coro::AnyEvent, and how to run it (and not to block). Seems to be
87 the most common source of confusion.
88 - try to catch people naively blocking in an event callback.
89 - work around the perl filehandle bug issue in conjunction with
90 older common::sense (as indirectly pointed out by ZSystem).
91 - clarify the "not from signal handlers" section.
92
935.2 Sun Oct 4 14:54:24 CEST 2009
94 - Coro::Storable destroyed the prototypes of the functions it wrapped.
95 - export rouse_cb and rouse_wait by default now.
96 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
97 - new method $state->swap_sv.
98 - added section on "windows process emulation" to the manpage,
99 after a not-so-fruitful (nor-friendly) "discussion" with chip
100 salzenberg (discussion implies arguments, but his only arguments
101 were ad-hominems, one wonders why he started it in the first
102 place). I hope this explains it well enough for him to understand,
103 and maybe well enough for others to understand.
104 - use common::sense everywhere now.
105 - idle callbacks are no longer supported, use idle coros instead.
106 - print a thread listing when a deadlock is detected.
107
1085.17 Sat Aug 22 23:09:31 CEST 2009
109 - work around a bug in the perl debugger causing crashes
110 when running under the debugger by marking _pool_handler as nodebug.
111 - speed up Coro::async considerably.
112 - try some hacks to get netbsd to work "more often" - their broken
113 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
114 - convert Coro to AE 5.0 API.
115
1165.162 Tue Jul 28 04:04:03 CEST 2009
117 - perl 5.8.2 is now minimum requirement.
118 - skip t/19_handle.t on broken windows perls.
119
1205.161 Wed Jul 22 04:47:38 CEST 2009
121 - Coro::AnyEvent::poll could have a different prototype when EV was
122 used as backend (analyzed by Tatsuhiko Miyagawa).
123 - Coro::AnyEvent errornously initialised the event loop when loaded,
124 not on demand.
125 - try to workaround rare */t/01_unblock.t failures.
126
1275.16 Tue Jul 21 01:44:37 CEST 2009
128 - Coro::AnyEvent failed to hook into the event loop
129 when no threads had been readied between detecting
130 the event loop and actually running it.
131 - considerably speed up Coro::Select by taking avdantage
132 of AnyEvent > 4.8 and some other optimisations.
133 - implement paragraph readline mode in Coro::Handle
134 (based on patches by Zsbán Ambrus).
135 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
136 and analyzed by Yasuhiro MATSUMOTO).
137 - clarified libcoro license and copyright.
138 - someone stole my EXTRA_META!!!
139 - implement Coro::Select::patch_pp_sselect and it's brother,
140 for hardcode select overriding.
141
1425.151 Mon Jul 6 05:41:57 CEST 2009
143 - backport to windows process emulation code again (patch by
144 Yasuhiro MATSUMOTO).
145 - slightly update Coro::MakeMaker.
146
1475.15 Tue Jun 30 10:28:06 CEST 2009
148 - deprecate Coro::Socket, document how to get ipv6 support via
149 AnyEvent::Socket instead.
150 - implement signal->wait ($cb) interface, similar to semaphores.
151 - work around SvOK not supporting getmagic, so we have to getmagic
152 to test for undef :/ (reported by Matthias Waldorf).
153 - load Coro::AnyEvent in all modules using AnyEvent.
154 - work around perl corrupting our internal data structures,
155 reported by Tokuhiro Matsuno.
156 - enable per-coroutine real and cpu time gathering
157 (Coro::State::enable_times).
158
1595.14 Wed Jun 24 01:37:48 CEST 2009
160 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
161 as this seems to have been a difficult concept (poll, sleep, idle,
162 idle_upto).
163 - add Coro::AnyEvent::readable/writable functions.
164 - clarify Coro::EV/Event/AnyEvent manpages.
165 - free per-thread global scalars in the thread calling ->cancel, to
166 avoid crashes when $_, $@ etc., are magical but some of those
167 had already been freed.
168 - "unexperimentalise" the callback interface for Coro::Semaphore.
169 - speed up ready queue management/context switching by using a linked
170 list instead of an array (~5-10%).
171 - implement "watch" command in Coro::Debug shells.
172 - for fun, implement time-slicing as an example in the manpage.
173 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
174 Coro::Event, use the normal AnyEvent handling instead of dieing
175 (the same is true for Coro::Handle).
176 - properly document Coro::EV::timed_io_once.
177 - avoid unneccessary ->cancel calls in Coro::Handle.
178 - maybe make it work on mingw32 with win32 backend
179 (based on patch by Yasuhiro Matsumoto).
180
1815.132 Fri May 29 09:00:39 CEST 2009
182 - do not keep a reference to the argument itself in
183 Coro::Semaphore::guard, as it could change later.
184 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
185 should support a prepare callback.
186
1875.131 Mon Mar 16 23:20:37 CET 2009
188 - implement and document Coro->suspend, Coro->resume.
189 - fix Coro::Select implementation to not (often) close
190 the passed file descriptors (testcase provided by pippijn).
191
1925.13 Mon Dec 15 21:51:42 CET 2008
193 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
194 - don't set diehook to C<undef> but instead to NULL, to avoid
195 spurious warnings.
196 - fix a lot of bugs in Coro::SemaphoreSet.
197 - Coro::SemaphoreSet will less often create a semaphore needlessly.
198 - add Coro::SemaphoreSet::count and wait methods.
199 - take advantage of the new Guard module.
200 - deprecate Coro::guard.
201 - try to fix the dreaded 01_unblock tests once more. I hate it when
202 testsuites need more fixing than the code they are supposed to test.
203 - croak in more cases when a required callback isn't resolvable.
204 - fix some minor issues in Coro::State->call/eval.
205 - use current coroutine context instead of a temporary one
206 when temporarily switching to another coroutine.
207 - do not call C-level on_destroy handlers during global destruction,
208 to avoid needless segfaults.
209
2105.12 Sun Dec 7 13:30:38 CET 2008
211 - add default config for MirOS, which seems to be a bug-to-bug
212 compatible fork of openbsd ("world domination by releasing
213 openbsd cvs before the openbsd folks do it" or so :).
214 - free_padlist did destroy the names pad, not good, but didn't
215 seem to bother perl - this could fix issues such as eval ""
216 inside a function called from multiple coroutines.
217 - use a different method to detect destruction time.
218 - be more careful when freeing padlists just before global
219 destruction.
220 - fixed and expanded the call/cc example.
221 - renamed _terminate to _coro_run.
222 - new method Coro::Channel->shutdown.
223 - try pthreads on openbsd <4.4 (broken sigaltstack, will
224 pthreads fare better?).
225 - be less picky about destroying "a" running coroutine.
226
2275.11 Tue Nov 25 21:49:05 CET 2008
228 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
229 working code with failed assertions, introducing more bugs than
230 it fixes, requiring elaborate workarounds :(
231
2325.1 Mon Nov 24 08:54:59 CET 2008
233 - wrote a small introductory tutorial - Coro::Intro.
234 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
235 - Coro::Select did errornously dup the file descriptors
236 and didn't work with all AnyEvent backends.
237 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
238 LWP data transfers.
239 - disassociate c contexts from coro objects - this is agruably more
240 correct, but mostly allows sharing of cctxs between coro and state
241 objects, for added memory savings and speed increases.
242 - bumped $Coro::POOL_RSS up to 32kb by default.
243 - no longer set the optype to OP_CUSTOM, as B::* understandably
244 doesn't like this very much (and we *are* a type of entersub).
245 - implement state cloning, just to prove that call/cc can be done.
246 - automatically load Coro::AnyEvent in Coro::Handle.
247 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
248 do not have this method (and don't need it either).
249 - speed up generic anyevent methods in Coro::Handle by using rouse
250 callbacks.
251 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
252 others. It also makes the debugger happier, as you can trace
253 through the idle threads now.
254 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
255 - eg/event was pretty broken.
256 - better 5.8.6 compatibility.
257
2585.0 Thu Nov 20 10:35:05 CET 2008
259 - NEW ARCHITECTURE: use the latest 4.x version if you experience
260 stability issues.
261 - bump API version to 7 - all dependents must be recompiled.
262 - removed timed_* functions - they were not being used anyways
263 and should be replaced by a more generic mechanism -
264 and were annoying to support anyways :)
265 - removed SemaphoreSet's waiter method - use sem method instead.
266 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
267 - async_pool did free a scalar value twice
268 ("Attempt to unreference...").
269 - fix a longstanding bug where calling terminate on a coro that
270 was waiting for a semaphore that was just becoming available
271 would cause a deadlock (semaphore would get into a state where
272 it was available but waiters were still blocked).
273 - calling throw on a coroutine that is waiting for a semaphore will
274 no longer make it acquire the semaphore (and thus leak a count).
275 - perl's process emulation is now not even theoretically supported
276 anymore.
277 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
278 conversion of callback-style to blocking-style.
279 - new methods $coro->schedule_to and ->cede_to, to specifically
280 schedule or cede to a specific coroutine.
281 - new function Coro::Semaphore::wait.
282 - use named constants in Coro::Channel (Richard Hundt).
283 - directly patch the entersub opcode calling SLF functions (cede,
284 transfer and so on). this does speed up context switching, but
285 more importanly, it frees us from the hardcoded behaviour of
286 entersub, so we might actually be able to return something from
287 those functions and atcually create new ones.
288 - take advantage of __builtin_frame_address on gcc.
289 - expose THX in coroapi (not sure whether this was a wise decision,
290 as "threaded" perls are running at half speed anyways).
291 - implement execute_slf (schedule-like-function) interface that makes
292 it possible to implement schedule-like-functions in XS.
293 - use new SLF interface to massively speed up Coro::EV by roughly a
294 factor of two.
295 - used new SLF interface to massively speed up Coro::Semaphore by a
296 factor of three.
297 - used new SLF interface to speed up Coro::AIO by roughly a factor of
298 four and reduce its memory usage considerably.
299 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
300 for a nice speedup and vastly more correct behaviour. Also implement
301 a new method "sem" to get at the underlying semaphore object.
302 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
303 (in comparison) 20-40% speedup.
304 - used new SLF interface to reimplement Coro::Signal gaining
305 some unknown (because I was too lazy), but certain, speedup, and also
306 making signals reliable for the first time.
307 - used new SLF interface and other optimisations to speed up async_pool
308 by a factor of two. It also doesn't rely on perl's exception mechanism
309 to exit anymore. The overhead for terminating an async_pool, coro over
310 a normal async is now very small.
311 - sped up coroutine creation/destruction by 40%.
312 - forgot to include Coro/libcoro/README in the dist for all these years.
313 - work around a freebsd pthreads bug (manual testcancel is required as
314 pthread_cond_wait isn't a cancellation point on freebsd).
315 - use new rouse functions to speed up and simplify Coro::BDB.
316 - make "prefer perl native functions" work with threaded perls.
317 - condense Coro::Debug ps output, hint at v and w flags.
318 - (libcoro) lots of minor cleanups and portability improvements.
319
3204.914 Wed Nov 19 12:54:18 CET 2008
321 - fix a disastrous bug in the readline optimisation
322 introduced in 4.801.
323
3244.913 Sat Nov 15 07:58:28 CET 2008
325 - async_pool did free a scalar value twice
326 ("Attempt to unreference...").
327
3284.912 Thu Nov 13 18:31:23 CET 2008
329 - minor cleanups.
330 - use much larger stacks on linux and perl < 5.8.8.
331 - Coro::Debug::new_unix_server did not unlink the socket
332 when destroyed.
333
3344.911 Tue Nov 11 04:26:17 CET 2008
335 - "port" to threaded perls.
336
3374.91 Mon Nov 10 05:36:38 CET 2008
338 - the ->throw exception object no longer leaks.
339 - creating a new cctx leaked a scopestack entry (memleak).
340 - new coroutines didn't get created with a zero flags field
341 (unknown impact).
342 - calling ->throw on a not-yet-started coroutine should now work
343 instead of being ignored.
344 - ->throw is now supported on Coro::State objects.
345 - clean up cctx creation code a bit.
346 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
347
3484.9 Sat Nov 8 17:45:27 CET 2008
349 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
350 - (libcoro) no longer leak threads in the experimental pthread backend,
351 also speed it up considerably.
352 - (libcoro) do not rely on makecontext passing void *'s unscathed.
353 - fix compiletime dependencies on libcoro in the Makefile.
354 - cctx_count wasn't always updated properly.
355 - Coro::State::cctx_stacksize wasn't applied correctly.
356 - new function Coro::State::cctx_max_idle.
357 - the default max number of idle C contexts is now 4.
358 - (libcoro) try harder to get _setjmp/_longjmp.
359 - (libcoro) cleanup and extend the libcoro API to officially
360 allow the creation of empty source contexts.
361 - very experimental workaround for the totally broken netbsd platform.
362 - tried to hack around openbsd bugs.
363
3644.804 Wed Nov 5 16:36:00 CET 2008
365 - Coro::Debug::new_unix_server would not create a non-blocking listening
366 socket, sometimes causing freezes.
367 - (libcoro) fix misaligned stack points for setjmp and assembly
368 methods, which can cause crashes on x86/x86_64 with a sufficiently
369 aggressive compiler.
370 - new function: Coro::Debug::new_tcp_server.
371 - move ->throw into the Coro class because it only works on coro objects.
372
3734.803 Mon Nov 3 17:16:12 CET 2008
374 - (libcoro) use a global asm statement to become independent of gcc
375 otpimisations for CORO_ASM (thanks to pippijn for the idea).
376 - try to workaround yet another broken bsd, this time dragonfly.
377
3784.802 Thu Oct 30 10:56:12 CET 2008
379 - support -fno-omit-frame-pointer on x86 with the assembly method.
380 - tune 01_unblock.t tests a bit.
381
3824.801 Wed Oct 22 18:33:37 CEST 2008
383 - improve readline speed for very long "lines".
384 - backport to 5.8.8.
385
3864.8 Thu Oct 2 13:34:40 CEST 2008
387 - new function Coro::AIO::aio_wait.
388 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
389 - greatly speed up and reduce memory usage of Coro::AIO requests.
390 - implement some other µ-optimisations.
391
3924.749 Mon Sep 29 14:40:12 CEST 2008
393 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
394
3954.748 Sat Sep 27 14:03:19 CEST 2008
396 - implement, but do not document, PerlIO::cede(granularity).
397 - Coro::Storable forgot to wrap Storable::pstore.
398 - work around the multitude of leaks and memory corruption
399 bugs in PerlIO::via by using our own C-level perliol. As a side
400 effect, Coro::Storable is now much, much, much faster.
401
4024.747 Tue Sep 23 01:59:41 CEST 2008
403 - fix a per-cv memleak (one empty array was leaked per
404 code reference).
405 - avoid a crash in coro->call|rss when the coroutine was already
406 destroyed (most noticably when using Coro::Debug::ps :)
407 - also protect *Storable::FILE.
408 - push up default storable granularity to 20ms.
409
4104.746 Sun Sep 21 03:22:20 CEST 2008
411 - be more insistent on locking Storable against reentrancy
412 in Coro::Storable.
413 - move swap_def?v and throw to Coro::State, as documented.
414
4154.745 Thu Jul 24 00:14:38 CEST 2008
416 - remove debugging code related to MgPV_nolen_const, also try to
417 make it compile with perl 5.8.6 (yes, apple apparently loves
418 outdated software). Reported by John S.
419
4204.744 Tue Jul 8 22:06:35 CEST 2008
421 - correctly provide default DIE/WARN handlers as documented.
422 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
423 implementations inside perl work fine for us.
424
4254.743 Mon Jun 16 00:21:57 CEST 2008
426 - when using Coro::EV without running EV::loop it could
427 result in busy-waiting for events, this has been fixed.
428 - reduce codesize and improve performance by using EV_DEFAULT_UC.
429
4304.742 Sat May 31 14:10:21 CEST 2008
431 - implement a workaround for (some) perl <5.8.8 versions.
432 - require EV 3.3+.
433
4344.741 Fri May 30 23:33:09 CEST 2008
435 - tell netbsd how utterly broken their imitation of an OS is
436 and refuse to build by default if pthreads are in use.
437 - switch to "s" method on all bsd's by default, as their ucontext
438 stuff seems just too broken.
439 - fix a bug in Coro::Select.
440
4414.74 Thu May 29 20:05:31 CEST 2008
442 - do not test Coro::LWP for lack of dependencies.
443 - do not test Coro::Select for lack of working perls.
444
4454.73 Thu May 29 2008
446 - fix a bug in Coro::EV which would cause it to block despite
447 there being runnable coroutines.
448 - sprinkle "no warnings" freely over everything, also suppress
449 warnings for some other modules.
450 - fix typo in WSAEWOULDBLOCK.
451
4524.72 Sun May 25 05:14:36 CEST 2008
453 - tweak META.yaml a bit, unfortunately, there is no documented way
454 to have optional dependencies with CPAN. doh :(
455 - avoid running some tests on windows because they would fail due to
456 perl bug (broken fork, broken pipes...).
457 - work around perl on windows bugs where perl returns undocumented
458 error codes for sysread, syswrite etc. by taking advantage
459 of AnyEvent's workaround for that problem.
460 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
461 a common perl implementation bug on windows.
462 - use unix domain sockets in testsuite to work around
463 common perl implementation bugs on widows (they are emulated by
464 tcp sockets on windows. ugh.)
465
4664.71 Sat May 24 20:01:27 CEST 2008
467 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
468 - take advantage of async name resolution of AnyEvent::Util.
469 - work around brutal inet_aton override in Coro::LWP.
470 - take advantage of the readyhook in Coro::EV, for smoother
471 scheduling.
472
4734.7 Sun May 11 00:32:19 CEST 2008
474 - completely reworked the Coro manpage.
475 - added Coro::AnyEvent, generic event loop integration.
476 - implement cancel, ready and kill commands in Coro::Debug.
477 - document find_coro in Coro::Debug.
478 - incompatible change: rename has_stack to has_cctx.
479 - Coro::AIO and Coro::BDB no longer force event model detection,
480 use AnyEvent::AIO and AnyEvent::BDB.
481
4824.6 Sat Apr 26 10:05:14 CEST 2008
483 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
484 by the Coro module. It was a mistake to have it in the first place.
485 - (experimental) support for activestate perl 5.10 (method "w").
486 - (experimental) support for strawberry perl (method "a").
487 - coro_sigelem_set did not return a value although it had to,
488 actual impact unknown.
489
4904.51 Mon Apr 14 13:28:27 CEST 2008
491 - make it compile again on 5.8.
492
4934.50 Thu Apr 10 09:43:17 CEST 2008
494 - I did it twice! (see 4.49).
495
4964.49 Sun Apr 6 21:23:31 CEST 2008
497 - grr, instead of compiling the recent changes on 5.10 only they
498 were compiled on 5.8 only.
499
5004.48 Sun Apr 6 20:36:46 CEST 2008
501 - allow coroutine switches during eval's under 5.10.x, as it seems
502 the parser is a per-interpreter option now, so this is safe
503 (this might fix the odd crashing bug).
504 - drop support for 5.9.x versions: they are dead, jim.
505
5064.47 Sun Apr 6 00:37:52 CEST 2008
507 - force cctx allocation on API calls: we know we need to force one
508 and gcc actually manages to confuse our heuristic nowadays,
509 leading to crashes and worse.
510 - document force_cctx.
511
5124.46 Fri Apr 4 22:05:43 CEST 2008
513 - upgrade libcoro, resulting in pthread-backend (which was only created
514 to fulfill the rules of the programming languages shootout).
515
5164.45 Thu Mar 13 11:55:36 CET 2008
517 - fix a file leaking bug in eg/mhyttpd that would allow
518 downloading of any file (reported by oesi).
519 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
520 (also add testcase).
521 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
522 apparently having loads of fun with that).
523 - implement $state->swap_defsv, ->swap_defav and document ->throw.
524
5254.4 Wed Feb 13 16:44:29 CET 2008
526 - only assume .cfi pseudo isns exist on GNU/Linux.
527 - add get_timed method to Coro::Channels.
528 - fixed Coro::Debug manpage.
529 - perl 5.11 compatbility improvement based on patch by
530 Andreas König.
531
5324.37 Sun Jan 20 11:25:23 CET 2008
533 - soften the check for an active parser for perl 5.10 (avoiding
534 "Coro::State::transfer called while parsing" in many cases).
535
5364.36 Sun Jan 13 10:53:56 CET 2008
537 - reset diehook when terminating from an async_pool as to not
538 trigger any __DIE__ handlers.
539
5404.35 Sun Jan 13 04:14:13 CET 2008
541 - "bt" debug command now displays any exceptions
542 from longmess and also skips the innermost
543 stackframes, giving more useufl output.
544 - allow backtraces in coroutines blocked in Coro::EV,
545 at a <1% speed hit.
546 - handle localising of $SIG{__WARN__} and __DIE__
547 properly (with a proper amount of dirty hacking).
548
5494.34 Sat Dec 22 17:49:53 CET 2007
550 - upgrade to EV version 2.0 API.
551
5524.33 Mon Dec 17 08:36:12 CET 2007
553 - make Coro::AIO etc. loadable in the absence of EV.
554
5554.32 Mon Dec 17 07:46:02 CET 2007
556 - majorly improved Coro::Handle's performance with Coro::EV.
557 - implemented the until now mythical Coro::BDB module.
558 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
559
5604.31 Wed Dec 5 12:32:39 CET 2007
561 - remove warn statement form Coro::Util.
562
5634.3 Tue Dec 4 20:33:14 CET 2007
564 - calls to the idle function could cause stack corruption
565 when the stack changed.
8 - do no longer rely on the presence of EV::DNS if EV is used 566 - do no longer rely on the presence of EV::DNS if EV is used
9 (because it is gone), but instead take avdantage of EV::ADNS 567 (because it is gone), but instead take avdantage of EV::ADNS
10 if available. 568 if available.
11 - add ($) prototypes to all functions in Coro::Storable. 569 - add ($) prototypes to all functions in Coro::Storable.
570 - use a conventional (safer) idle callback in Coro::EV.
571 - do accept quickly in Coro::Debug to avoid endless loops.
12 572
134.22 Fri Nov 30 16:04:04 CET 2007 5734.22 Fri Nov 30 16:04:04 CET 2007
14 - really use optimised versions for Event and EV in Coro::Util 574 - really use optimised versions for Event and EV in Coro::Util
15 and Coro::Handle. 575 and Coro::Handle.
