3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: destroy gets only called on cancel: fix(?) 4TODO: channel->maxsize(newsize)?
5TODO: http://www.microsoft.com/msj/archive/s2ce.aspx
5 6
7 - add a big "Coro thread life cycle" section to "man Coro".
8 - try a tentative workaround against the breakage that 5.13 has
9 introduced without depreciation period. sigh.
10
115.36 Sun Feb 13 05:33:41 CET 2011
12 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
13 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
14 method call.
15 - undocument Coro::Timer::sleep and obsolete whole module.
16 - optimise Coro::Timer::timeout memory and cpu usage.
17 - slightly updated Coro::Intro for recent changes.
18 - do not initialise PL_dirty anymore.
19
205.25 Thu Nov 11 01:08:39 CET 2010
21 - try a different approach on netbsd - netbsd 5 finally has marginally
22 working pthreads, but still broken ucontext/sigaltstack.
23 - openbsd 4.8 finally got their act together, Coro works out of the box
24 with asm, setjmp and pthreads (no change, just informational).
25
265.24 Sat Oct 23 11:27:12 CEST 2010
27 - port to the EV 4.0 API.
28 - work around bugs in mingw32, making strawberry perl work
29 out of the box.
30 - correctly modify Coro::AIO function prototypes
31 so that they reflect the "no optional parameters" rule.
32 - "ported" libcoro to C++.
33
345.23 Mon May 17 18:50:42 CEST 2010
35 - be more resistant to ordering changes when initialising
36 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
37 Waldorf).
38 - document that perl 5.12 deliberately removed support for cloning.
39
405.22 Wed Apr 14 03:55:35 CEST 2010
41 - correctly return udnef on errors in Coro::Handle::read/write
42 (testcase by Marc Mims).
43 - convert Coro::Util into a "perl compatibility wrapper" - the functions
44 are less useful now, but are drop-in replacements for existing
45 functions, listing better alternatives in the documentation. This also
46 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
47 with Coro::Util::inet_aton.
48 - do not override $Coro::idle unconditionally in Coro.pm, as other
49 modules could have provided their own idle coro already
50 (for exmaple, Coro::AnyEvent).
51 - fix Coro::Util::gethost* functions.
52 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
53
545.21 Wed Dec 16 07:19:51 CET 2009
55 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
56 together.
57 - add some examples on how to combine other event loops with Coro in
58 Coro::AnyEvent, and how to run it (and not to block). Seems to be
59 the most common source of confusion.
60 - try to catch people naively blocking in an event callback.
61 - work around the perl filehandle bug issue in conjunction with
62 older common::sense (as indirectly pointed out by ZSystem).
63 - clarify the "not from signal handlers" section.
64
655.2 Sun Oct 4 14:54:24 CEST 2009
66 - Coro::Storable destroyed the prototypes of the functions it wrapped.
67 - export rouse_cb and rouse_wait by default now.
68 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
69 - new method $state->swap_sv.
70 - added section on "windows process emulation" to the manpage,
71 after a not-so-fruitful (nor-friendly) "discussion" with chip
72 salzenberg (discussion implies arguments, but his only arguments
73 were ad-hominems, one wonders why he started it in the first
74 place). I hope this explains it well enough for him to understand,
75 and maybe well enough for others to understand.
76 - use common::sense everywhere now.
77 - idle callbacks are no longer supported, use idle coros instead.
78 - print a thread listing when a deadlock is detected.
79
805.17 Sat Aug 22 23:09:31 CEST 2009
81 - work around a bug in the perl debugger causing crashes
82 when running under the debugger by marking _pool_handler as nodebug.
83 - speed up Coro::async considerably.
84 - try some hacks to get netbsd to work "more often" - their broken
85 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
86 - convert Coro to AE 5.0 API.
87
885.162 Tue Jul 28 04:04:03 CEST 2009
89 - perl 5.8.2 is now minimum requirement.
90 - skip t/19_handle.t on broken windows perls.
91
925.161 Wed Jul 22 04:47:38 CEST 2009
93 - Coro::AnyEvent::poll could have a different prototype when EV was
94 used as backend (analyzed by Tatsuhiko Miyagawa).
95 - Coro::AnyEvent errornously initialised the event loop when loaded,
96 not on demand.
97 - try to workaround rare */t/01_unblock.t failures.
98
995.16 Tue Jul 21 01:44:37 CEST 2009
100 - Coro::AnyEvent failed to hook into the event loop
101 when no threads had been readied between detecting
102 the event loop and actually running it.
103 - considerably speed up Coro::Select by taking avdantage
104 of AnyEvent > 4.8 and some other optimisations.
105 - implement paragraph readline mode in Coro::Handle
106 (based on patches by Zsbán Ambrus).
107 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
108 and analyzed by Yasuhiro MATSUMOTO).
109 - clarified libcoro license and copyright.
110 - someone stole my EXTRA_META!!!
111 - implement Coro::Select::patch_pp_sselect and it's brother,
112 for hardcode select overriding.
113
1145.151 Mon Jul 6 05:41:57 CEST 2009
115 - backport to windows process emulation code again (patch by
116 Yasuhiro MATSUMOTO).
117 - slightly update Coro::MakeMaker.
118
1195.15 Tue Jun 30 10:28:06 CEST 2009
120 - deprecate Coro::Socket, document how to get ipv6 support via
121 AnyEvent::Socket instead.
122 - implement signal->wait ($cb) interface, similar to semaphores.
123 - work around SvOK not supporting getmagic, so we have to getmagic
124 to test for undef :/ (reported by Matthias Waldorf).
125 - load Coro::AnyEvent in all modules using AnyEvent.
126 - work around perl corrupting our internal data structures,
127 reported by Tokuhiro Matsuno.
128 - enable per-coroutine real and cpu time gathering
129 (Coro::State::enable_times).
130
1315.14 Wed Jun 24 01:37:48 CEST 2009
132 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
133 as this seems to have been a difficult concept (poll, sleep, idle,
134 idle_upto).
135 - add Coro::AnyEvent::readable/writable functions.
136 - clarify Coro::EV/Event/AnyEvent manpages.
137 - free per-thread global scalars in the thread calling ->cancel, to
138 avoid crashes when $_, $@ etc., are magical but some of those
139 had already been freed.
140 - "unexperimentalise" the callback interface for Coro::Semaphore.
141 - speed up ready queue management/context switching by using a linked
142 list instead of an array (~5-10%).
143 - implement "watch" command in Coro::Debug shells.
144 - for fun, implement time-slicing as an example in the manpage.
145 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
146 Coro::Event, use the normal AnyEvent handling instead of dieing
147 (the same is true for Coro::Handle).
148 - properly document Coro::EV::timed_io_once.
149 - avoid unneccessary ->cancel calls in Coro::Handle.
150 - maybe make it work on mingw32 with win32 backend
151 (based on patch by Yasuhiro Matsumoto).
152
1535.132 Fri May 29 09:00:39 CEST 2009
154 - do not keep a reference to the argument itself in
155 Coro::Semaphore::guard, as it could change later.
156 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
157 should support a prepare callback.
158
1595.131 Mon Mar 16 23:20:37 CET 2009
160 - implement and document Coro->suspend, Coro->resume.
161 - fix Coro::Select implementation to not (often) close
162 the passed file descriptors (testcase provided by pippijn).
163
1645.13 Mon Dec 15 21:51:42 CET 2008
165 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
166 - don't set diehook to C<undef> but instead to NULL, to avoid
167 spurious warnings.
168 - fix a lot of bugs in Coro::SemaphoreSet.
169 - Coro::SemaphoreSet will less often create a semaphore needlessly.
170 - add Coro::SemaphoreSet::count and wait methods.
171 - take advantage of the new Guard module.
172 - deprecate Coro::guard.
173 - try to fix the dreaded 01_unblock tests once more. I hate it when
174 testsuites need more fixing than the code they are supposed to test.
175 - croak in more cases when a required callback isn't resolvable.
176 - fix some minor issues in Coro::State->call/eval.
177 - use current coroutine context instead of a temporary one
178 when temporarily switching to another coroutine.
179 - do not call C-level on_destroy handlers during global destruction,
180 to avoid needless segfaults.
181
1825.12 Sun Dec 7 13:30:38 CET 2008
183 - add default config for MirOS, which seems to be a bug-to-bug
184 compatible fork of openbsd ("world domination by releasing
185 openbsd cvs before the openbsd folks do it" or so :).
186 - free_padlist did destroy the names pad, not good, but didn't
187 seem to bother perl - this could fix issues such as eval ""
188 inside a function called from multiple coroutines.
189 - use a different method to detect destruction time.
190 - be more careful when freeing padlists just before global
191 destruction.
192 - fixed and expanded the call/cc example.
193 - renamed _terminate to _coro_run.
194 - new method Coro::Channel->shutdown.
195 - try pthreads on openbsd <4.4 (broken sigaltstack, will
196 pthreads fare better?).
197 - be less picky about destroying "a" running coroutine.
198
1995.11 Tue Nov 25 21:49:05 CET 2008
200 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
201 working code with failed assertions, introducing more bugs than
202 it fixes, requiring elaborate workarounds :(
203
2045.1 Mon Nov 24 08:54:59 CET 2008
205 - wrote a small introductory tutorial - Coro::Intro.
206 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
207 - Coro::Select did errornously dup the file descriptors
208 and didn't work with all AnyEvent backends.
209 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
210 LWP data transfers.
211 - disassociate c contexts from coro objects - this is agruably more
212 correct, but mostly allows sharing of cctxs between coro and state
213 objects, for added memory savings and speed increases.
214 - bumped $Coro::POOL_RSS up to 32kb by default.
215 - no longer set the optype to OP_CUSTOM, as B::* understandably
216 doesn't like this very much (and we *are* a type of entersub).
217 - implement state cloning, just to prove that call/cc can be done.
218 - automatically load Coro::AnyEvent in Coro::Handle.
219 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
220 do not have this method (and don't need it either).
221 - speed up generic anyevent methods in Coro::Handle by using rouse
222 callbacks.
223 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
224 others. It also makes the debugger happier, as you can trace
225 through the idle threads now.
226 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
227 - eg/event was pretty broken.
228 - better 5.8.6 compatibility.
229
2305.0 Thu Nov 20 10:35:05 CET 2008
231 - NEW ARCHITECTURE: use the latest 4.x version if you experience
232 stability issues.
233 - bump API version to 7 - all dependents must be recompiled.
234 - removed timed_* functions - they were not being used anyways
235 and should be replaced by a more generic mechanism -
236 and were annoying to support anyways :)
237 - removed SemaphoreSet's waiter method - use sem method instead.
238 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
239 - async_pool did free a scalar value twice
240 ("Attempt to unreference...").
241 - fix a longstanding bug where calling terminate on a coro that
242 was waiting for a semaphore that was just becoming available
243 would cause a deadlock (semaphore would get into a state where
244 it was available but waiters were still blocked).
245 - calling throw on a coroutine that is waiting for a semaphore will
246 no longer make it acquire the semaphore (and thus leak a count).
247 - perl's process emulation is now not even theoretically supported
248 anymore.
249 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
250 conversion of callback-style to blocking-style.
251 - new methods $coro->schedule_to and ->cede_to, to specifically
252 schedule or cede to a specific coroutine.
253 - new function Coro::Semaphore::wait.
254 - use named constants in Coro::Channel (Richard Hundt).
255 - directly patch the entersub opcode calling SLF functions (cede,
256 transfer and so on). this does speed up context switching, but
257 more importanly, it frees us from the hardcoded behaviour of
258 entersub, so we might actually be able to return something from
259 those functions and atcually create new ones.
260 - take advantage of __builtin_frame_address on gcc.
261 - expose THX in coroapi (not sure whether this was a wise decision,
262 as "threaded" perls are running at half speed anyways).
263 - implement execute_slf (schedule-like-function) interface that makes
264 it possible to implement schedule-like-functions in XS.
265 - use new SLF interface to massively speed up Coro::EV by roughly a
266 factor of two.
267 - used new SLF interface to massively speed up Coro::Semaphore by a
268 factor of three.
269 - used new SLF interface to speed up Coro::AIO by roughly a factor of
270 four and reduce its memory usage considerably.
271 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
272 for a nice speedup and vastly more correct behaviour. Also implement
273 a new method "sem" to get at the underlying semaphore object.
274 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
275 (in comparison) 20-40% speedup.
276 - used new SLF interface to reimplement Coro::Signal gaining
277 some unknown (because I was too lazy), but certain, speedup, and also
278 making signals reliable for the first time.
279 - used new SLF interface and other optimisations to speed up async_pool
280 by a factor of two. It also doesn't rely on perl's exception mechanism
281 to exit anymore. The overhead for terminating an async_pool, coro over
282 a normal async is now very small.
283 - sped up coroutine creation/destruction by 40%.
284 - forgot to include Coro/libcoro/README in the dist for all these years.
285 - work around a freebsd pthreads bug (manual testcancel is required as
286 pthread_cond_wait isn't a cancellation point on freebsd).
287 - use new rouse functions to speed up and simplify Coro::BDB.
288 - make "prefer perl native functions" work with threaded perls.
289 - condense Coro::Debug ps output, hint at v and w flags.
290 - (libcoro) lots of minor cleanups and portability improvements.
291
2924.914 Wed Nov 19 12:54:18 CET 2008
293 - fix a disastrous bug in the readline optimisation
294 introduced in 4.801.
295
2964.913 Sat Nov 15 07:58:28 CET 2008
297 - async_pool did free a scalar value twice
298 ("Attempt to unreference...").
299
3004.912 Thu Nov 13 18:31:23 CET 2008
301 - minor cleanups.
302 - use much larger stacks on linux and perl < 5.8.8.
303 - Coro::Debug::new_unix_server did not unlink the socket
304 when destroyed.
305
3064.911 Tue Nov 11 04:26:17 CET 2008
307 - "port" to threaded perls.
308
3094.91 Mon Nov 10 05:36:38 CET 2008
310 - the ->throw exception object no longer leaks.
311 - creating a new cctx leaked a scopestack entry (memleak).
312 - new coroutines didn't get created with a zero flags field
313 (unknown impact).
314 - calling ->throw on a not-yet-started coroutine should now work
315 instead of being ignored.
316 - ->throw is now supported on Coro::State objects.
317 - clean up cctx creation code a bit.
318 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
319
3204.9 Sat Nov 8 17:45:27 CET 2008
321 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
322 - (libcoro) no longer leak threads in the experimental pthread backend,
323 also speed it up considerably.
324 - (libcoro) do not rely on makecontext passing void *'s unscathed.
325 - fix compiletime dependencies on libcoro in the Makefile.
326 - cctx_count wasn't always updated properly.
327 - Coro::State::cctx_stacksize wasn't applied correctly.
328 - new function Coro::State::cctx_max_idle.
329 - the default max number of idle C contexts is now 4.
330 - (libcoro) try harder to get _setjmp/_longjmp.
331 - (libcoro) cleanup and extend the libcoro API to officially
332 allow the creation of empty source contexts.
333 - very experimental workaround for the totally broken netbsd platform.
334 - tried to hack around openbsd bugs.
335
3364.804 Wed Nov 5 16:36:00 CET 2008
337 - Coro::Debug::new_unix_server would not create a non-blocking listening
338 socket, sometimes causing freezes.
339 - (libcoro) fix misaligned stack points for setjmp and assembly
340 methods, which can cause crashes on x86/x86_64 with a sufficiently
341 aggressive compiler.
342 - new function: Coro::Debug::new_tcp_server.
343 - move ->throw into the Coro class because it only works on coro objects.
344
3454.803 Mon Nov 3 17:16:12 CET 2008
346 - (libcoro) use a global asm statement to become independent of gcc
347 otpimisations for CORO_ASM (thanks to pippijn for the idea).
348 - try to workaround yet another broken bsd, this time dragonfly.
349
3504.802 Thu Oct 30 10:56:12 CET 2008
351 - support -fno-omit-frame-pointer on x86 with the assembly method.
352 - tune 01_unblock.t tests a bit.
353
3544.801 Wed Oct 22 18:33:37 CEST 2008
355 - improve readline speed for very long "lines".
356 - backport to 5.8.8.
357
3584.8 Thu Oct 2 13:34:40 CEST 2008
359 - new function Coro::AIO::aio_wait.
360 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
361 - greatly speed up and reduce memory usage of Coro::AIO requests.
362 - implement some other µ-optimisations.
363
3644.749 Mon Sep 29 14:40:12 CEST 2008
365 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
366
3674.748 Sat Sep 27 14:03:19 CEST 2008
368 - implement, but do not document, PerlIO::cede(granularity).
369 - Coro::Storable forgot to wrap Storable::pstore.
370 - work around the multitude of leaks and memory corruption
371 bugs in PerlIO::via by using our own C-level perliol. As a side
372 effect, Coro::Storable is now much, much, much faster.
373
3744.747 Tue Sep 23 01:59:41 CEST 2008
375 - fix a per-cv memleak (one empty array was leaked per
376 code reference).
377 - avoid a crash in coro->call|rss when the coroutine was already
378 destroyed (most noticably when using Coro::Debug::ps :)
379 - also protect *Storable::FILE.
380 - push up default storable granularity to 20ms.
381
3824.746 Sun Sep 21 03:22:20 CEST 2008
383 - be more insistent on locking Storable against reentrancy
384 in Coro::Storable.
385 - move swap_def?v and throw to Coro::State, as documented.
386
3874.745 Thu Jul 24 00:14:38 CEST 2008
388 - remove debugging code related to MgPV_nolen_const, also try to
389 make it compile with perl 5.8.6 (yes, apple apparently loves
390 outdated software). Reported by John S.
391
3924.744 Tue Jul 8 22:06:35 CEST 2008
393 - correctly provide default DIE/WARN handlers as documented.
394 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
395 implementations inside perl work fine for us.
396
3974.743 Mon Jun 16 00:21:57 CEST 2008
398 - when using Coro::EV without running EV::loop it could
399 result in busy-waiting for events, this has been fixed.
400 - reduce codesize and improve performance by using EV_DEFAULT_UC.
401
4024.742 Sat May 31 14:10:21 CEST 2008
403 - implement a workaround for (some) perl <5.8.8 versions.
404 - require EV 3.3+.
405
4064.741 Fri May 30 23:33:09 CEST 2008
407 - tell netbsd how utterly broken their imitation of an OS is
408 and refuse to build by default if pthreads are in use.
409 - switch to "s" method on all bsd's by default, as their ucontext
410 stuff seems just too broken.
411 - fix a bug in Coro::Select.
412
4134.74 Thu May 29 20:05:31 CEST 2008
414 - do not test Coro::LWP for lack of dependencies.
415 - do not test Coro::Select for lack of working perls.
416
4174.73 Thu May 29 2008
418 - fix a bug in Coro::EV which would cause it to block despite
419 there being runnable coroutines.
420 - sprinkle "no warnings" freely over everything, also suppress
421 warnings for some other modules.
422 - fix typo in WSAEWOULDBLOCK.
423
4244.72 Sun May 25 05:14:36 CEST 2008
425 - tweak META.yaml a bit, unfortunately, there is no documented way
426 to have optional dependencies with CPAN. doh :(
427 - avoid running some tests on windows because they would fail due to
428 perl bug (broken fork, broken pipes...).
429 - work around perl on windows bugs where perl returns undocumented
430 error codes for sysread, syswrite etc. by taking advantage
431 of AnyEvent's workaround for that problem.
432 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
433 a common perl implementation bug on windows.
434 - use unix domain sockets in testsuite to work around
435 common perl implementation bugs on widows (they are emulated by
436 tcp sockets on windows. ugh.)
437
4384.71 Sat May 24 20:01:27 CEST 2008
439 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
440 - take advantage of async name resolution of AnyEvent::Util.
441 - work around brutal inet_aton override in Coro::LWP.
442 - take advantage of the readyhook in Coro::EV, for smoother
443 scheduling.
444
4454.7 Sun May 11 00:32:19 CEST 2008
446 - completely reworked the Coro manpage.
447 - added Coro::AnyEvent, generic event loop integration.
448 - implement cancel, ready and kill commands in Coro::Debug.
449 - document find_coro in Coro::Debug.
450 - incompatible change: rename has_stack to has_cctx.
451 - Coro::AIO and Coro::BDB no longer force event model detection,
452 use AnyEvent::AIO and AnyEvent::BDB.
453
4544.6 Sat Apr 26 10:05:14 CEST 2008
455 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
456 by the Coro module. It was a mistake to have it in the first place.
457 - (experimental) support for activestate perl 5.10 (method "w").
458 - (experimental) support for strawberry perl (method "a").
459 - coro_sigelem_set did not return a value although it had to,
460 actual impact unknown.
461
4624.51 Mon Apr 14 13:28:27 CEST 2008
463 - make it compile again on 5.8.
464
4654.50 Thu Apr 10 09:43:17 CEST 2008
466 - I did it twice! (see 4.49).
467
4684.49 Sun Apr 6 21:23:31 CEST 2008
469 - grr, instead of compiling the recent changes on 5.10 only they
470 were compiled on 5.8 only.
471
4724.48 Sun Apr 6 20:36:46 CEST 2008
473 - allow coroutine switches during eval's under 5.10.x, as it seems
474 the parser is a per-interpreter option now, so this is safe
475 (this might fix the odd crashing bug).
476 - drop support for 5.9.x versions: they are dead, jim.
477
4784.47 Sun Apr 6 00:37:52 CEST 2008
479 - force cctx allocation on API calls: we know we need to force one
480 and gcc actually manages to confuse our heuristic nowadays,
481 leading to crashes and worse.
482 - document force_cctx.
483
4844.46 Fri Apr 4 22:05:43 CEST 2008
485 - upgrade libcoro, resulting in pthread-backend (which was only created
486 to fulfill the rules of the programming languages shootout).
487
4884.45 Thu Mar 13 11:55:36 CET 2008
489 - fix a file leaking bug in eg/mhyttpd that would allow
490 downloading of any file (reported by oesi).
491 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
492 (also add testcase).
493 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
494 apparently having loads of fun with that).
495 - implement $state->swap_defsv, ->swap_defav and document ->throw.
496
4974.4 Wed Feb 13 16:44:29 CET 2008
498 - only assume .cfi pseudo isns exist on GNU/Linux.
499 - add get_timed method to Coro::Channels.
500 - fixed Coro::Debug manpage.
501 - perl 5.11 compatbility improvement based on patch by
502 Andreas König.
503
5044.37 Sun Jan 20 11:25:23 CET 2008
505 - soften the check for an active parser for perl 5.10 (avoiding
506 "Coro::State::transfer called while parsing" in many cases).
507
5084.36 Sun Jan 13 10:53:56 CET 2008
509 - reset diehook when terminating from an async_pool as to not
510 trigger any __DIE__ handlers.
511
5124.35 Sun Jan 13 04:14:13 CET 2008
513 - "bt" debug command now displays any exceptions
514 from longmess and also skips the innermost
515 stackframes, giving more useufl output.
516 - allow backtraces in coroutines blocked in Coro::EV,
517 at a <1% speed hit.
518 - handle localising of $SIG{__WARN__} and __DIE__
519 properly (with a proper amount of dirty hacking).
520
5214.34 Sat Dec 22 17:49:53 CET 2007
522 - upgrade to EV version 2.0 API.
523
5244.33 Mon Dec 17 08:36:12 CET 2007
525 - make Coro::AIO etc. loadable in the absence of EV.
526
5274.32 Mon Dec 17 07:46:02 CET 2007
528 - majorly improved Coro::Handle's performance with Coro::EV.
529 - implemented the until now mythical Coro::BDB module.
530 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
531
5324.31 Wed Dec 5 12:32:39 CET 2007
533 - remove warn statement form Coro::Util.
534
5354.3 Tue Dec 4 20:33:14 CET 2007
536 - calls to the idle function could cause stack corruption
537 when the stack changed.
538 - do no longer rely on the presence of EV::DNS if EV is used
539 (because it is gone), but instead take avdantage of EV::ADNS
540 if available.
541 - add ($) prototypes to all functions in Coro::Storable.
542 - use a conventional (safer) idle callback in Coro::EV.
543 - do accept quickly in Coro::Debug to avoid endless loops.
544
5454.22 Fri Nov 30 16:04:04 CET 2007
546 - really use optimised versions for Event and EV in Coro::Util
547 and Coro::Handle.
548
5494.21 Sun Nov 25 10:48:59 CET 2007
550 - fix a spurious memory read.
551 - Coro::EV no longer keeps the eventloop "alive".
552
5534.2 Fri Nov 9 20:47:05 CET 2007
554 - enable/disable tracing from a new coroutine, not a pooled one.
555 - fix a memleak in Coro::Event.
556 - removed killall call from fork_eval.
557 - made sure store_fd is already loaded so that fork_eval
558 does not have to parse autoload in each subprocess.
559 - only use assembly method if -O switch is in $Config{optimize}.
560 - add (optional) Coro::EV module, so far the best event loop module
561 directly supported by Coro.
562 - if the event model is EV, use EV::DNS to resolve
563 stuff in Coro::Util.
564 - don't get confused by multiple event notifications in Coro::Handle.
565 - initial support for EV (libevent interface).
566 - require Event and EV using configure_requires, to force their existance.
567
5684.13 Wed Oct 24 07:26:45 CEST 2007
569 - add Coro::Storable::blocking_thaw.
570 - use a vastly more complicated technique to localise
571 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
572 - use a coroutine for the idle callback Coro::Event,
573 instead of running Event in the current coroutine context.
574 This also catches recursive invocations.
575 - actually report fork errors in gethostbyname and inet_aton.
576
5774.11 Thu Oct 11 02:40:24 CEST 2007
578 - port to threaded perls.
579
5804.1 Thu Oct 11 02:38:16 CEST 2007
581 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
582 be local to each coro (see Coro::State).
583 - incompatible change: for very deep reasons, cede and cede_notself
584 cannot return anything, so nothing will be returned.
585 - possibly bring back 5.10 compatibility (untested).
586 - work around stupid (and wrong) warning on 5.10 :(.
587 - overlay the saved state over the context stack. This saves
588 a few hundred bytes per coroutine on average and also
589 speeds up context switching a bit.
590 - further tune default stack sizes.
591 - (more) correctly calculate stack usage in coro_rss.
592 - Coro::Storable::blocking_* did not properly lock
593 resulting in races between coroutines.
594 - added Coro::Storable::guard.
595 - stopping to trace a coroutine could destroy the cctx of
596 an unrelated coroutine.
597 - explain the relationship between Perl and C coroutines in
598 more detail in Coro::State.
599 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
600 causing a fork per resolve. This also affected Coro::Socket.
601 - switch to a separate stack in $coro->call/eval to avoid
602 invalidating pointers.
603
6044.03 Sat Oct 6 21:24:00 CEST 2007
605 - added Coro::throw method.
606 - minor code cleanups.
607
6084.02 Sat Oct 6 02:36:47 CEST 2007
609 - fix a very minor per-coroutine memleak (a single codereference).
610 - fixed a bug where the currently in-use c context would be freed
611 prematurely (can happen only when programs change the stacksize
612 or use tracing).
613 - tracing can no longer keep a coro alive after it terminated.
614 - do static branch prediction in the common path for gcc. gives
615 about 2-5% speed improvement here.
616
6174.01 Fri Oct 5 22:10:49 CEST 2007
618 - instead of recreating *a* standard output handle we simply
619 use STDOUT, which is faster and hopefully more robust.
620
6214.0 Fri Oct 5 12:56:00 CEST 2007
622 - incompatibly changed Coro::Storable::freeze.
623 - major new feature: added Coro::Debug, for interactive coroutine
624 debugging, tracing and much more.
625 - major bug fix: unbelievable, but true: $_, $/ and many other
626 "saved" variables actually weren't being saved. This has been fixed,
627 of course, while increasing performance while losing all the save
628 flags.
629 - save flags are gone, and all the api functions dealing with them.
630 - added Coro::Semaphore::adjust.
631 - added Coro::Util::fork_eval.
632 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
633 - added Coro::killall.
634 - reduce initial stack sizes to allow for "micro-coroutines".
635 - better async_pool resource management, moved parts of async_pool
636 handling to XS (major speed improvement).
637 - actually croak before modifying important data structures.
638 - refuse to transfer while compiling.
639 - possibly support eval EXPR better now.
640 - enable assembly per default on linux+bsd x86+amd64.
641 - all internal members were renamed _something for easier subclassing.
642 - many minor tweaks.
643
6443.63 Wed May 16 14:10:06 CEST 2007
645 - implement handcoded assembly for x86/amd64 SVR ABI.
646
6473.62 Fri Apr 27 21:36:06 CEST 2007
648 - upgrade libcoro (which might set unwind info correctly).
649 - change default on linux to setjmp/longjmp.
650
6513.61 Thu Apr 19 12:36:18 CEST 2007
652 - Coro::Storable caused an endless loop when thawing invalid
653 pst's sometimes.
654 - use a Semaphore in Coro::Storable, as Storable doesn't
655 seem to be reentrant (although it is documented to
656 be threadsafe...).
657 - fix Coro::Signal to bring back the original unreliable
658 but stateful semantics.
659 - fixed a lot of typos in Coro.pm (patch submitted by David
660 Steinbrunner, which applied flawlessly).
661
6623.6 Sat Apr 14 17:13:31 CEST 2007
6 - added some bugfixes to get eg/myhttpd working again. 663 - added some bugfixes to get eg/myhttpd working again.
664 - added Coro::Storable for often-cede'ing freeze/thaw.
665 - try to do a clean exit when a coroutine calls exit
666 (EXPERIMENTAL).
667 - got rid of indirect call through _coro_init.
668 - updated the partly antique examples in eg/ to
669 work again and be a bit less magic, too.
670 - fixed Coro::Signal semantics to work as documented again.
7 671
83.55 Sun Mar 25 01:20:47 CET 2007 6723.55 Sun Mar 25 01:20:47 CET 2007
9 - add SAVE_DEFFH to save the default filehandle and enable 673 - add SAVE_DEFFH to save the default filehandle and enable
10 it by default. 674 it by default.
11 - finally move socket-operations from Coro::Socket to Coro::Handle 675 - finally move socket-operations from Coro::Socket to Coro::Handle
