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)). 6TODO: __GCC_HAVE_DWARF2_CFI_ASM
7 7
8 - Coro::EV I/O watchers were not interruptible by exceptions
9 (Coro::State::throw).
10 - use fd -1 in mmap.
11 - cast I32 to int in error message printf.
12 - warn about broken so-called "hardened" kernels.
13
146.08 Fri Apr 13 12:05:47 CEST 2012
15 - be more aggressive about exiting like perl does - formerly,
16 exiting from the non-main thread would not execute END blocks.
17
186.07 Fri Nov 11 21:21:48 CET 2011
19 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
20 - update ecb.h.
21
226.06 Mon Aug 8 23:59:48 CEST 2011
23 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
24 backend, which is an order of magnitude slower. unfortunately, cygwins
25 pthread implementation isn't very complete either, so allocate the stack
26 twice just to be sure.
27 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
28 in its ithreaded perl - best recompile cygwin and use the 'w'indows
29 backend for much better performance. also disable ithreads for
30 even better performance...).
31
326.05 Thu Aug 4 21:36:36 CEST 2011
33 - blush, condvar values would not be propagated from send to recv anymore
34 (reported by Chip Salzenberg).
35 - use exponential increase for the readline buffer length in
36 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
37
386.04 Wed Aug 3 17:15:45 CEST 2011
39 - use even more efficient and more compatible condvars for
40 compatibility to AnyEvent 6.x :)
41 - more inconsequential ecb.h updates.
42
436.03 Wed Aug 3 11:41:30 CEST 2011
44 - change how Coro patches AnyEvent condvars for compatibility to
45 AnyEvent 6.x.
46 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
47 hasn't been included.
48
496.02 Wed Jul 13 04:35:19 CEST 2011
50 - "improve portability to Gentoo" - gentoo manages to put perl variables
51 in memory areas that are farther than 2gb apart, which the jit couldn't
52 handle and barfed. now it's just a bit slower on gentoo and similar
53 systems.
54
556.01 Sun Jul 3 12:31:14 CEST 2011
56 - workarounds are good, but the test for whether pthreads are used
57 was not good. thisone should be better.
58 - check differently whether gcc generates cfi instructions itself.
59
606.0 Wed Jun 29 19:43:35 CEST 2011
61 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
62 destroyed and cleaned up automatically (e.g. async { schedule }).
63 - implement a JIT compiler for part of the thread switch code,
64 which gives a 50% speed improvement on threaded perls, and
65 about 4% on non-thraeded perls (so threaded perls now finally
66 reach about half the speed of non-threaded perls).
67 - slightly modernise Coro::Intro, add section about rouse functions.
68 - avoid DEFSV and ERRSV, giving another 10% improvement
69 in thread switching.
70 - Coro::State->is_destroyed is now called is_zombie.
71 - implement a Coro->safe_cancel method that might fail, but
72 cancels in a "safer" way if it succeeds.
73 - add preliminary support for DEBUGGING perls.
74 - get rid of two hash-accesses when initialising a new Coro - this
75 speeds up coro creation by almost a factor of two.
76 - croak when a coro that is being cancelled tries to block
77 (e.g. while executing a guard block), instead of crashing or
78 deadlocking.
79 - use a more robust and also faster method to identify Coro::State
80 objects - speeds up everything a bit.
81 - implement Coro->cancel in XS for a 20% speed improvement, and to
82 be able to implement mutual cancellation.
83 - speed up context switches by a percent or two by more efficiently
84 allocating context stack entries.
85 - implement Coro->join and Coro->on_destroy in XS for a speedup and
86 a reduction in memory use.
87 - cancelling a coro while it itself is cancelling another coro is
88 now supported and working, instead of triggering an assertion.
89 - be a bit more crash-resistant when calling (buggy) on_destroy
90 callbacks (best effort).
91 - move on_destroy into the slf_frame, to allow extension slf
92 functions to have destructors.
93 - get rid if coro refcounting - simply crash in other interpreter
94 threads by nulling the pointers on clone.
95 - simplify warn/die hook handling when loading Coro - the convoluted
96 logic seems to be no longer neccessary.
97 - use libecb instead of our own home-grown gcc hacks.
98 - document alternatives to Coro::LWP. Please use them :)
99 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
100 sigaltstack. Really. wine suffers from it, erlang suffers from it,
101 and it's known since at least 2006.
102
1035.372 Wed Feb 23 06:14:30 CET 2011
104 - apparently mingw doesn't provide a working gettimeofday, try to
105 work around that by relying on Time::HiRes (indirectly brought to
106 my attention by Max Maischein).
107 - fix some portability issues when Time::HiRes was used.
108
1095.371 Mon Feb 21 14:36:08 CET 2011
110 - backport to windows process emulation code again.
111
1125.37 Sat Feb 19 07:49:44 CET 2011
113 - add a big "Coro thread life cycle" section to "man Coro".
114 - try a tentative workaround against the breakage that 5.13 has
115 introduced without depreciation period. sigh.
116 - no longer use Time::HiRes if gettimeofday is available, which
117 saves quite a lot of memory.
118
1195.36 Sun Feb 13 05:33:41 CET 2011
120 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
121 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
122 method call.
123 - undocument Coro::Timer::sleep and obsolete whole module.
124 - optimise Coro::Timer::timeout memory and cpu usage.
125 - slightly updated Coro::Intro for recent changes.
126 - do not initialise PL_dirty anymore.
127
1285.25 Thu Nov 11 01:08:39 CET 2010
129 - try a different approach on netbsd - netbsd 5 finally has marginally
130 working pthreads, but still broken ucontext/sigaltstack.
131 - openbsd 4.8 finally got their act together, Coro works out of the box
132 with asm, setjmp and pthreads (no change, just informational).
133
1345.24 Sat Oct 23 11:27:12 CEST 2010
135 - port to the EV 4.0 API.
136 - work around bugs in mingw32, making strawberry perl work
137 out of the box.
138 - correctly modify Coro::AIO function prototypes
139 so that they reflect the "no optional parameters" rule.
140 - "ported" libcoro to C++.
141
1425.23 Mon May 17 18:50:42 CEST 2010
143 - be more resistant to ordering changes when initialising
144 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
145 Waldorf).
146 - document that perl 5.12 deliberately removed support for cloning.
147
1485.22 Wed Apr 14 03:55:35 CEST 2010
149 - correctly return udnef on errors in Coro::Handle::read/write
150 (testcase by Marc Mims).
151 - convert Coro::Util into a "perl compatibility wrapper" - the functions
152 are less useful now, but are drop-in replacements for existing
153 functions, listing better alternatives in the documentation. This also
154 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
155 with Coro::Util::inet_aton.
156 - do not override $Coro::idle unconditionally in Coro.pm, as other
157 modules could have provided their own idle coro already
158 (for exmaple, Coro::AnyEvent).
159 - fix Coro::Util::gethost* functions.
160 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
161
1625.21 Wed Dec 16 07:19:51 CET 2009
163 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
164 together.
165 - add some examples on how to combine other event loops with Coro in
166 Coro::AnyEvent, and how to run it (and not to block). Seems to be
167 the most common source of confusion.
168 - try to catch people naively blocking in an event callback.
169 - work around the perl filehandle bug issue in conjunction with
170 older common::sense (as indirectly pointed out by ZSystem).
171 - clarify the "not from signal handlers" section.
172
1735.2 Sun Oct 4 14:54:24 CEST 2009
174 - Coro::Storable destroyed the prototypes of the functions it wrapped.
175 - export rouse_cb and rouse_wait by default now.
176 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
177 - new method $state->swap_sv.
178 - added section on "windows process emulation" to the manpage,
179 after a not-so-fruitful (nor-friendly) "discussion" with chip
180 salzenberg (discussion implies arguments, but his only arguments
181 were ad-hominems, one wonders why he started it in the first
182 place). I hope this explains it well enough for him to understand,
183 and maybe well enough for others to understand.
184 - use common::sense everywhere now.
185 - idle callbacks are no longer supported, use idle coros instead.
186 - print a thread listing when a deadlock is detected.
187
1885.17 Sat Aug 22 23:09:31 CEST 2009
189 - work around a bug in the perl debugger causing crashes
190 when running under the debugger by marking _pool_handler as nodebug.
191 - speed up Coro::async considerably.
192 - try some hacks to get netbsd to work "more often" - their broken
193 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
194 - convert Coro to AE 5.0 API.
195
1965.162 Tue Jul 28 04:04:03 CEST 2009
197 - perl 5.8.2 is now minimum requirement.
198 - skip t/19_handle.t on broken windows perls.
199
2005.161 Wed Jul 22 04:47:38 CEST 2009
201 - Coro::AnyEvent::poll could have a different prototype when EV was
202 used as backend (analyzed by Tatsuhiko Miyagawa).
203 - Coro::AnyEvent errornously initialised the event loop when loaded,
204 not on demand.
205 - try to workaround rare */t/01_unblock.t failures.
206
2075.16 Tue Jul 21 01:44:37 CEST 2009
208 - Coro::AnyEvent failed to hook into the event loop
209 when no threads had been readied between detecting
210 the event loop and actually running it.
211 - considerably speed up Coro::Select by taking avdantage
212 of AnyEvent > 4.8 and some other optimisations.
213 - implement paragraph readline mode in Coro::Handle
214 (based on patches by Zsbán Ambrus).
215 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
216 and analyzed by Yasuhiro MATSUMOTO).
217 - clarified libcoro license and copyright.
218 - someone stole my EXTRA_META!!!
219 - implement Coro::Select::patch_pp_sselect and it's brother,
220 for hardcode select overriding.
221
2225.151 Mon Jul 6 05:41:57 CEST 2009
223 - backport to windows process emulation code again (patch by
224 Yasuhiro MATSUMOTO).
225 - slightly update Coro::MakeMaker.
226
2275.15 Tue Jun 30 10:28:06 CEST 2009
228 - deprecate Coro::Socket, document how to get ipv6 support via
229 AnyEvent::Socket instead.
230 - implement signal->wait ($cb) interface, similar to semaphores.
231 - work around SvOK not supporting getmagic, so we have to getmagic
232 to test for undef :/ (reported by Matthias Waldorf).
233 - load Coro::AnyEvent in all modules using AnyEvent.
234 - work around perl corrupting our internal data structures,
235 reported by Tokuhiro Matsuno.
236 - enable per-coroutine real and cpu time gathering
237 (Coro::State::enable_times).
238
2395.14 Wed Jun 24 01:37:48 CEST 2009
240 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
241 as this seems to have been a difficult concept (poll, sleep, idle,
242 idle_upto).
243 - add Coro::AnyEvent::readable/writable functions.
244 - clarify Coro::EV/Event/AnyEvent manpages.
245 - free per-thread global scalars in the thread calling ->cancel, to
246 avoid crashes when $_, $@ etc., are magical but some of those
247 had already been freed.
248 - "unexperimentalise" the callback interface for Coro::Semaphore.
249 - speed up ready queue management/context switching by using a linked
250 list instead of an array (~5-10%).
251 - implement "watch" command in Coro::Debug shells.
252 - for fun, implement time-slicing as an example in the manpage.
253 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
254 Coro::Event, use the normal AnyEvent handling instead of dieing
255 (the same is true for Coro::Handle).
256 - properly document Coro::EV::timed_io_once.
257 - avoid unneccessary ->cancel calls in Coro::Handle.
258 - maybe make it work on mingw32 with win32 backend
259 (based on patch by Yasuhiro Matsumoto).
260
2615.132 Fri May 29 09:00:39 CEST 2009
262 - do not keep a reference to the argument itself in
263 Coro::Semaphore::guard, as it could change later.
264 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
265 should support a prepare callback.
266
2675.131 Mon Mar 16 23:20:37 CET 2009
268 - implement and document Coro->suspend, Coro->resume.
269 - fix Coro::Select implementation to not (often) close
270 the passed file descriptors (testcase provided by pippijn).
271
2725.13 Mon Dec 15 21:51:42 CET 2008
273 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
274 - don't set diehook to C<undef> but instead to NULL, to avoid
275 spurious warnings.
276 - fix a lot of bugs in Coro::SemaphoreSet.
277 - Coro::SemaphoreSet will less often create a semaphore needlessly.
278 - add Coro::SemaphoreSet::count and wait methods.
279 - take advantage of the new Guard module.
280 - deprecate Coro::guard.
281 - try to fix the dreaded 01_unblock tests once more. I hate it when
282 testsuites need more fixing than the code they are supposed to test.
283 - croak in more cases when a required callback isn't resolvable.
284 - fix some minor issues in Coro::State->call/eval.
285 - use current coroutine context instead of a temporary one
286 when temporarily switching to another coroutine.
287 - do not call C-level on_destroy handlers during global destruction,
288 to avoid needless segfaults.
289
2905.12 Sun Dec 7 13:30:38 CET 2008
291 - add default config for MirOS, which seems to be a bug-to-bug
292 compatible fork of openbsd ("world domination by releasing
293 openbsd cvs before the openbsd folks do it" or so :).
294 - free_padlist did destroy the names pad, not good, but didn't
295 seem to bother perl - this could fix issues such as eval ""
296 inside a function called from multiple coroutines.
297 - use a different method to detect destruction time.
298 - be more careful when freeing padlists just before global
299 destruction.
300 - fixed and expanded the call/cc example.
301 - renamed _terminate to _coro_run.
302 - new method Coro::Channel->shutdown.
303 - try pthreads on openbsd <4.4 (broken sigaltstack, will
304 pthreads fare better?).
305 - be less picky about destroying "a" running coroutine.
306
3075.11 Tue Nov 25 21:49:05 CET 2008
308 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
309 working code with failed assertions, introducing more bugs than
310 it fixes, requiring elaborate workarounds :(
311
3125.1 Mon Nov 24 08:54:59 CET 2008
313 - wrote a small introductory tutorial - Coro::Intro.
314 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
315 - Coro::Select did errornously dup the file descriptors
316 and didn't work with all AnyEvent backends.
317 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
318 LWP data transfers.
319 - disassociate c contexts from coro objects - this is agruably more
320 correct, but mostly allows sharing of cctxs between coro and state
321 objects, for added memory savings and speed increases.
322 - bumped $Coro::POOL_RSS up to 32kb by default.
323 - no longer set the optype to OP_CUSTOM, as B::* understandably
324 doesn't like this very much (and we *are* a type of entersub).
325 - implement state cloning, just to prove that call/cc can be done.
326 - automatically load Coro::AnyEvent in Coro::Handle.
327 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
328 do not have this method (and don't need it either).
329 - speed up generic anyevent methods in Coro::Handle by using rouse
330 callbacks.
331 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
332 others. It also makes the debugger happier, as you can trace
333 through the idle threads now.
334 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
335 - eg/event was pretty broken.
336 - better 5.8.6 compatibility.
337
3385.0 Thu Nov 20 10:35:05 CET 2008
339 - NEW ARCHITECTURE: use the latest 4.x version if you experience
340 stability issues.
341 - bump API version to 7 - all dependents must be recompiled.
342 - removed timed_* functions - they were not being used anyways
343 and should be replaced by a more generic mechanism -
344 and were annoying to support anyways :)
345 - removed SemaphoreSet's waiter method - use sem method instead.
346 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
347 - async_pool did free a scalar value twice
348 ("Attempt to unreference...").
349 - fix a longstanding bug where calling terminate on a coro that
350 was waiting for a semaphore that was just becoming available
351 would cause a deadlock (semaphore would get into a state where
352 it was available but waiters were still blocked).
353 - calling throw on a coroutine that is waiting for a semaphore will
354 no longer make it acquire the semaphore (and thus leak a count).
355 - perl's process emulation is now not even theoretically supported
356 anymore.
357 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
358 conversion of callback-style to blocking-style.
359 - new methods $coro->schedule_to and ->cede_to, to specifically
360 schedule or cede to a specific coroutine.
361 - new function Coro::Semaphore::wait.
362 - use named constants in Coro::Channel (Richard Hundt).
363 - directly patch the entersub opcode calling SLF functions (cede,
364 transfer and so on). this does speed up context switching, but
365 more importanly, it frees us from the hardcoded behaviour of
366 entersub, so we might actually be able to return something from
367 those functions and atcually create new ones.
368 - take advantage of __builtin_frame_address on gcc.
369 - expose THX in coroapi (not sure whether this was a wise decision,
370 as "threaded" perls are running at half speed anyways).
371 - implement execute_slf (schedule-like-function) interface that makes
372 it possible to implement schedule-like-functions in XS.
373 - use new SLF interface to massively speed up Coro::EV by roughly a
374 factor of two.
375 - used new SLF interface to massively speed up Coro::Semaphore by a
376 factor of three.
377 - used new SLF interface to speed up Coro::AIO by roughly a factor of
378 four and reduce its memory usage considerably.
379 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
380 for a nice speedup and vastly more correct behaviour. Also implement
381 a new method "sem" to get at the underlying semaphore object.
382 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
383 (in comparison) 20-40% speedup.
384 - used new SLF interface to reimplement Coro::Signal gaining
385 some unknown (because I was too lazy), but certain, speedup, and also
386 making signals reliable for the first time.
387 - used new SLF interface and other optimisations to speed up async_pool
388 by a factor of two. It also doesn't rely on perl's exception mechanism
389 to exit anymore. The overhead for terminating an async_pool, coro over
390 a normal async is now very small.
391 - sped up coroutine creation/destruction by 40%.
392 - forgot to include Coro/libcoro/README in the dist for all these years.
393 - work around a freebsd pthreads bug (manual testcancel is required as
394 pthread_cond_wait isn't a cancellation point on freebsd).
395 - use new rouse functions to speed up and simplify Coro::BDB.
396 - make "prefer perl native functions" work with threaded perls.
397 - condense Coro::Debug ps output, hint at v and w flags.
398 - (libcoro) lots of minor cleanups and portability improvements.
399
4004.914 Wed Nov 19 12:54:18 CET 2008
401 - fix a disastrous bug in the readline optimisation
402 introduced in 4.801.
403
4044.913 Sat Nov 15 07:58:28 CET 2008
405 - async_pool did free a scalar value twice
406 ("Attempt to unreference...").
407
4084.912 Thu Nov 13 18:31:23 CET 2008
409 - minor cleanups.
410 - use much larger stacks on linux and perl < 5.8.8.
411 - Coro::Debug::new_unix_server did not unlink the socket
412 when destroyed.
413
4144.911 Tue Nov 11 04:26:17 CET 2008
415 - "port" to threaded perls.
416
4174.91 Mon Nov 10 05:36:38 CET 2008
418 - the ->throw exception object no longer leaks.
419 - creating a new cctx leaked a scopestack entry (memleak).
420 - new coroutines didn't get created with a zero flags field
421 (unknown impact).
422 - calling ->throw on a not-yet-started coroutine should now work
423 instead of being ignored.
424 - ->throw is now supported on Coro::State objects.
425 - clean up cctx creation code a bit.
426 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
427
4284.9 Sat Nov 8 17:45:27 CET 2008
429 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
430 - (libcoro) no longer leak threads in the experimental pthread backend,
431 also speed it up considerably.
432 - (libcoro) do not rely on makecontext passing void *'s unscathed.
433 - fix compiletime dependencies on libcoro in the Makefile.
434 - cctx_count wasn't always updated properly.
435 - Coro::State::cctx_stacksize wasn't applied correctly.
436 - new function Coro::State::cctx_max_idle.
437 - the default max number of idle C contexts is now 4.
438 - (libcoro) try harder to get _setjmp/_longjmp.
439 - (libcoro) cleanup and extend the libcoro API to officially
440 allow the creation of empty source contexts.
441 - very experimental workaround for the totally broken netbsd platform.
442 - tried to hack around openbsd bugs.
443
4444.804 Wed Nov 5 16:36:00 CET 2008
445 - Coro::Debug::new_unix_server would not create a non-blocking listening
446 socket, sometimes causing freezes.
447 - (libcoro) fix misaligned stack points for setjmp and assembly
448 methods, which can cause crashes on x86/x86_64 with a sufficiently
449 aggressive compiler.
450 - new function: Coro::Debug::new_tcp_server.
451 - move ->throw into the Coro class because it only works on coro objects.
452
4534.803 Mon Nov 3 17:16:12 CET 2008
454 - (libcoro) use a global asm statement to become independent of gcc
455 otpimisations for CORO_ASM (thanks to pippijn for the idea).
456 - try to workaround yet another broken bsd, this time dragonfly.
457
4584.802 Thu Oct 30 10:56:12 CET 2008
459 - support -fno-omit-frame-pointer on x86 with the assembly method.
460 - tune 01_unblock.t tests a bit.
461
4624.801 Wed Oct 22 18:33:37 CEST 2008
463 - improve readline speed for very long "lines".
464 - backport to 5.8.8.
465
4664.8 Thu Oct 2 13:34:40 CEST 2008
467 - new function Coro::AIO::aio_wait.
468 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
469 - greatly speed up and reduce memory usage of Coro::AIO requests.
470 - implement some other µ-optimisations.
471
4724.749 Mon Sep 29 14:40:12 CEST 2008
473 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
474
4754.748 Sat Sep 27 14:03:19 CEST 2008
476 - implement, but do not document, PerlIO::cede(granularity).
477 - Coro::Storable forgot to wrap Storable::pstore.
478 - work around the multitude of leaks and memory corruption
479 bugs in PerlIO::via by using our own C-level perliol. As a side
480 effect, Coro::Storable is now much, much, much faster.
481
4824.747 Tue Sep 23 01:59:41 CEST 2008
483 - fix a per-cv memleak (one empty array was leaked per
484 code reference).
485 - avoid a crash in coro->call|rss when the coroutine was already
486 destroyed (most noticably when using Coro::Debug::ps :)
487 - also protect *Storable::FILE.
488 - push up default storable granularity to 20ms.
489
4904.746 Sun Sep 21 03:22:20 CEST 2008
491 - be more insistent on locking Storable against reentrancy
492 in Coro::Storable.
493 - move swap_def?v and throw to Coro::State, as documented.
494
4954.745 Thu Jul 24 00:14:38 CEST 2008
496 - remove debugging code related to MgPV_nolen_const, also try to
497 make it compile with perl 5.8.6 (yes, apple apparently loves
498 outdated software). Reported by John S.
499
5004.744 Tue Jul 8 22:06:35 CEST 2008
501 - correctly provide default DIE/WARN handlers as documented.
502 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
503 implementations inside perl work fine for us.
504
5054.743 Mon Jun 16 00:21:57 CEST 2008
506 - when using Coro::EV without running EV::loop it could
507 result in busy-waiting for events, this has been fixed.
508 - reduce codesize and improve performance by using EV_DEFAULT_UC.
509
5104.742 Sat May 31 14:10:21 CEST 2008
511 - implement a workaround for (some) perl <5.8.8 versions.
512 - require EV 3.3+.
513
5144.741 Fri May 30 23:33:09 CEST 2008
515 - tell netbsd how utterly broken their imitation of an OS is
516 and refuse to build by default if pthreads are in use.
517 - switch to "s" method on all bsd's by default, as their ucontext
518 stuff seems just too broken.
519 - fix a bug in Coro::Select.
520
5214.74 Thu May 29 20:05:31 CEST 2008
522 - do not test Coro::LWP for lack of dependencies.
523 - do not test Coro::Select for lack of working perls.
524
5254.73 Thu May 29 2008
526 - fix a bug in Coro::EV which would cause it to block despite
527 there being runnable coroutines.
528 - sprinkle "no warnings" freely over everything, also suppress
529 warnings for some other modules.
530 - fix typo in WSAEWOULDBLOCK.
531
5324.72 Sun May 25 05:14:36 CEST 2008
533 - tweak META.yaml a bit, unfortunately, there is no documented way
534 to have optional dependencies with CPAN. doh :(
535 - avoid running some tests on windows because they would fail due to
536 perl bug (broken fork, broken pipes...).
537 - work around perl on windows bugs where perl returns undocumented
538 error codes for sysread, syswrite etc. by taking advantage
539 of AnyEvent's workaround for that problem.
540 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
541 a common perl implementation bug on windows.
542 - use unix domain sockets in testsuite to work around
543 common perl implementation bugs on widows (they are emulated by
544 tcp sockets on windows. ugh.)
545
5464.71 Sat May 24 20:01:27 CEST 2008
547 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
548 - take advantage of async name resolution of AnyEvent::Util.
549 - work around brutal inet_aton override in Coro::LWP.
550 - take advantage of the readyhook in Coro::EV, for smoother
551 scheduling.
552
5534.7 Sun May 11 00:32:19 CEST 2008
554 - completely reworked the Coro manpage.
555 - added Coro::AnyEvent, generic event loop integration.
556 - implement cancel, ready and kill commands in Coro::Debug.
557 - document find_coro in Coro::Debug.
558 - incompatible change: rename has_stack to has_cctx.
559 - Coro::AIO and Coro::BDB no longer force event model detection,
560 use AnyEvent::AIO and AnyEvent::BDB.
561
5624.6 Sat Apr 26 10:05:14 CEST 2008
563 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
564 by the Coro module. It was a mistake to have it in the first place.
565 - (experimental) support for activestate perl 5.10 (method "w").
566 - (experimental) support for strawberry perl (method "a").
567 - coro_sigelem_set did not return a value although it had to,
568 actual impact unknown.
569
5704.51 Mon Apr 14 13:28:27 CEST 2008
571 - make it compile again on 5.8.
572
5734.50 Thu Apr 10 09:43:17 CEST 2008
574 - I did it twice! (see 4.49).
575
5764.49 Sun Apr 6 21:23:31 CEST 2008
577 - grr, instead of compiling the recent changes on 5.10 only they
578 were compiled on 5.8 only.
579
5804.48 Sun Apr 6 20:36:46 CEST 2008
581 - allow coroutine switches during eval's under 5.10.x, as it seems
582 the parser is a per-interpreter option now, so this is safe
583 (this might fix the odd crashing bug).
584 - drop support for 5.9.x versions: they are dead, jim.
585
5864.47 Sun Apr 6 00:37:52 CEST 2008
587 - force cctx allocation on API calls: we know we need to force one
588 and gcc actually manages to confuse our heuristic nowadays,
589 leading to crashes and worse.
590 - document force_cctx.
591
5924.46 Fri Apr 4 22:05:43 CEST 2008
593 - upgrade libcoro, resulting in pthread-backend (which was only created
594 to fulfill the rules of the programming languages shootout).
595
5964.45 Thu Mar 13 11:55:36 CET 2008
597 - fix a file leaking bug in eg/mhyttpd that would allow
598 downloading of any file (reported by oesi).
599 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
600 (also add testcase).
601 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
602 apparently having loads of fun with that).
603 - implement $state->swap_defsv, ->swap_defav and document ->throw.
604
6054.4 Wed Feb 13 16:44:29 CET 2008
606 - only assume .cfi pseudo isns exist on GNU/Linux.
607 - add get_timed method to Coro::Channels.
608 - fixed Coro::Debug manpage.
609 - perl 5.11 compatbility improvement based on patch by
610 Andreas König.
611
6124.37 Sun Jan 20 11:25:23 CET 2008
613 - soften the check for an active parser for perl 5.10 (avoiding
614 "Coro::State::transfer called while parsing" in many cases).
615
6164.36 Sun Jan 13 10:53:56 CET 2008
617 - reset diehook when terminating from an async_pool as to not
618 trigger any __DIE__ handlers.
619
6204.35 Sun Jan 13 04:14:13 CET 2008
621 - "bt" debug command now displays any exceptions
622 from longmess and also skips the innermost
623 stackframes, giving more useufl output.
624 - allow backtraces in coroutines blocked in Coro::EV,
625 at a <1% speed hit.
626 - handle localising of $SIG{__WARN__} and __DIE__
627 properly (with a proper amount of dirty hacking).
628
6294.34 Sat Dec 22 17:49:53 CET 2007
630 - upgrade to EV version 2.0 API.
631
6324.33 Mon Dec 17 08:36:12 CET 2007
633 - make Coro::AIO etc. loadable in the absence of EV.
634
6354.32 Mon Dec 17 07:46:02 CET 2007
636 - majorly improved Coro::Handle's performance with Coro::EV.
637 - implemented the until now mythical Coro::BDB module.
638 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
639
6404.31 Wed Dec 5 12:32:39 CET 2007
641 - remove warn statement form Coro::Util.
642
6434.3 Tue Dec 4 20:33:14 CET 2007
644 - calls to the idle function could cause stack corruption
645 when the stack changed.
646 - do no longer rely on the presence of EV::DNS if EV is used
647 (because it is gone), but instead take avdantage of EV::ADNS
648 if available.
649 - add ($) prototypes to all functions in Coro::Storable.
650 - use a conventional (safer) idle callback in Coro::EV.
651 - do accept quickly in Coro::Debug to avoid endless loops.
652
6534.22 Fri Nov 30 16:04:04 CET 2007
654 - really use optimised versions for Event and EV in Coro::Util
655 and Coro::Handle.
656
6574.21 Sun Nov 25 10:48:59 CET 2007
658 - fix a spurious memory read.
659 - Coro::EV no longer keeps the eventloop "alive".
660
6614.2 Fri Nov 9 20:47:05 CET 2007
8 - enable/disable tracing from a new coroutine, not a pooled one. 662 - enable/disable tracing from a new coroutine, not a pooled one.
9 - fix a memleak in Coro::Event. 663 - fix a memleak in Coro::Event.
10 - removed killall call from fork_eval. 664 - removed killall call from fork_eval.
11 - made sure store_fd is already loaded so that fork_eval 665 - made sure store_fd is already loaded so that fork_eval
12 does not have to parse autoload in each subprocess. 666 does not have to parse autoload in each subprocess.
667 - only use assembly method if -O switch is in $Config{optimize}.
668 - add (optional) Coro::EV module, so far the best event loop module
669 directly supported by Coro.
13 - if the event model is EV, use EV::DNS to resolve 670 - if the event model is EV, use EV::DNS to resolve
14 stuff in Coro::Util. 671 stuff in Coro::Util.
15 - don't get confused by multiple event notifications in Coro::Handle. 672 - don't get confused by multiple event notifications in Coro::Handle.
673 - initial support for EV (libevent interface).
674 - require Event and EV using configure_requires, to force their existance.
16 675
174.13 Wed Oct 24 07:26:45 CEST 2007 6764.13 Wed Oct 24 07:26:45 CEST 2007
18 - add Coro::Storable::blocking_thaw. 677 - add Coro::Storable::blocking_thaw.
