7 9
10 - Coro::SemaphoreSet->try did not actually work (analyzed by
11 SATO Kentaro).
12
136.41 Sat Sep 6 22:08:46 CEST 2014
14 - restore portability to perl 5.8.x.
15 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
16 up some memory, but fixes "use feature" and similar modules
17 when used inside a Coro.
18 - allow zero as argument to Coro::Channel to mean the same thing
19 as no argument. this works with older versions as well,
20 but wasn't legal until now.
21 - slightly better c header file detection.
22
236.39 Mon Jun 2 00:00:08 CEST 2014
24 - work around more incompatible changes in 5.20.
25
266.38 Sun Jun 1 21:54:23 CEST 2014
27 - check that perl slots actually have enough space to hold
28 interpreter variables.
29 - untested port to perl 5.19 (64 bit tmps indices) (reported
30 by Andreas König).
31 - croak when cancel is called without a thread context.
32
336.37 Tue Mar 4 13:27:33 CET 2014
34 - *sigh*, removed leftover debugging code from debugging a
35 perl bug, of all things.
36
376.36 Tue Mar 4 07:11:59 CET 2014
38 - semaphores would not clear the destroy hook when interrupted
39 by ->throw, causing segfaults or worse.
40 - ->throw on a thread waiting for a semaphore did not acquire
41 the semaphore, but also didn't wake up other waiters,
42 possibly causing a deadlock.
43 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
44 to report a full stacktrace, which should help find out
45 where the actual call is.
46 - "atomically" destroy data in slf_destroy, because it is
47 the right thing to do, just in case.
48 - disable ecb.h libm dependency, to compile on ancient systems
49 or under adverse conditions.
50
516.33 Mon Nov 18 11:26:27 CET 2013
52 - do not crash when freeing padlists with holes (in 5.18).
53 - tentative SVt_BIND 5.19 port/fix.
54
556.32 Tue Nov 5 15:35:35 CET 2013
56 - use a new algorithm to derive padlists for perl 5.18. The old
57 one could lead to 0-pointer accesses inside perl (reported
58 by Darin McBride).
59
606.31 Thu May 9 07:39:48 CEST 2013
61 - Coro::AIO requests would crash if the thread was ready'd
62 while the request was ongoing.
63
646.29 Wed May 8 02:55:18 CEST 2013
65 - when an on_destroy handler destructs the coro currently being
66 destructed a perl scalar could be accessed after being freed,
67 likely causing a crash.
68
696.28 Wed Mar 6 06:58:02 CET 2013
70 - clean remnants of existing __DIE__ and __WARN__ handlers so
71 they lose their magic and will not cause segfaults later
72 (testcase by Andrey Sagulin).
73 - improved Coro::State documentation a bit.
74 - Coro::Debug::command now flushes the output.
75 - add hack detection code for x32 abi, because the braindead slugs
76 who designed that made it look exactly like x86_64 without
77 providing proper compile time symbols to test for it. as a result,
78 this detection cannot work reliably.
79 - valgrind stack registering was broken.
80 - do not rely on Time::HiRes anymore in Coro::Debug.
81
826.23 Fri Dec 7 23:36:37 CET 2012
83 - use experimental fiber implementation on native windows
84 perls.
85 - use sizeof (void *) as multiplication factor for stack sizes,
86 to accomodate the totally braindamaged microsoft 64 bit "os".
87 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
88 activeperl 5.16 crashes when PerlIO_define_layer is called due
89 to some bug in the perl dll, strawberry perl at least passes
90 the testsuite.
91 - implement Coro::Handle->peeraddr/host/port, for slightly
92 improved compatibility with LWP.
93 - implement 5.17 compatibility by almost blindly applying a
94 good-looking patch by Father Chrysostomos.
95 - move stack management functions into libcoro 3.
96 - libcoro version 3 "released".
97 - support magic values as timed_io_once args.
98 - recommend AnyEvent 7+ or EV 4+, also require EV
99 version 4 or newer for Coro::EV.
100
1016.10 Tue Oct 9 01:14:27 CEST 2012
102 - updated ecb.h, it had a typo that caused it to not compile on many
103 big endian systems (reported by many people).
104 - disable memory fences in ecb.h to improve portability.
105
1066.09 Sat Oct 6 23:25:02 CEST 2012
107 - Coro::EV I/O watchers were not interruptible by exceptions
108 (Coro::State::throw) (testcase by sten).
109 - ->throw now puts threads into the ready queue, as this seems to
110 be expected by existing code, and code that doesn't cope with spurious
111 wakeups needs fixing anyway.
112 - use fd -1 in mmap.
113 - cast I32 to int in error message printf.
114 - warn about broken so-called "hardened" kernels.
115
1166.08 Fri Apr 13 12:05:47 CEST 2012
117 - be more aggressive about exiting like perl does - formerly,
118 exiting from the non-main thread would not execute END blocks.
119
1206.07 Fri Nov 11 21:21:48 CET 2011
121 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
122 - update ecb.h.
123
1246.06 Mon Aug 8 23:59:48 CEST 2011
125 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
126 backend, which is an order of magnitude slower. unfortunately, cygwins
127 pthread implementation isn't very complete either, so allocate the stack
128 twice just to be sure.
129 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
130 in its ithreaded perl - best recompile cygwin and use the 'w'indows
131 backend for much better performance. also disable ithreads for
132 even better performance...).
133
1346.05 Thu Aug 4 21:36:36 CEST 2011
135 - blush, condvar values would not be propagated from send to recv anymore
136 (reported by Chip Salzenberg).
137 - use exponential increase for the readline buffer length in
138 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
139
1406.04 Wed Aug 3 17:15:45 CEST 2011
141 - use even more efficient and more compatible condvars for
142 compatibility to AnyEvent 6.x :)
143 - more inconsequential ecb.h updates.
144
1456.03 Wed Aug 3 11:41:30 CEST 2011
146 - change how Coro patches AnyEvent condvars for compatibility to
147 AnyEvent 6.x.
148 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
149 hasn't been included.
150
1516.02 Wed Jul 13 04:35:19 CEST 2011
152 - "improve portability to Gentoo" - gentoo manages to put perl variables
153 in memory areas that are farther than 2gb apart, which the jit couldn't
154 handle and barfed. now it's just a bit slower on gentoo and similar
155 systems.
156
1576.01 Sun Jul 3 12:31:14 CEST 2011
158 - workarounds are good, but the test for whether pthreads are used
159 was not good. this one should be better.
160 - check differently whether gcc generates cfi instructions itself.
161
1626.0 Wed Jun 29 19:43:35 CEST 2011
163 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
164 destroyed and cleaned up automatically (e.g. async { schedule }).
165 - implement a JIT compiler for part of the thread switch code,
166 which gives a 50% speed improvement on threaded perls, and
167 about 4% on non-threaded perls (so threaded perls now finally
168 reach about half the speed of non-threaded perls).
169 - slightly modernise Coro::Intro, add section about rouse functions.
170 - avoid DEFSV and ERRSV, giving another 10% improvement
171 in thread switching.
172 - Coro::State->is_destroyed is now called is_zombie.
173 - implement a Coro->safe_cancel method that might fail, but
174 cancels in a "safer" way if it succeeds.
175 - add preliminary support for DEBUGGING perls.
176 - get rid of two hash-accesses when initialising a new Coro - this
177 speeds up coro creation by almost a factor of two.
178 - croak when a coro that is being cancelled tries to block
179 (e.g. while executing a guard block), instead of crashing or
180 deadlocking.
181 - use a more robust and also faster method to identify Coro::State
182 objects - speeds up everything a bit.
183 - implement Coro->cancel in XS for a 20% speed improvement, and to
184 be able to implement mutual cancellation.
185 - speed up context switches by a percent or two by more efficiently
186 allocating context stack entries.
187 - implement Coro->join and Coro->on_destroy in XS for a speedup and
188 a reduction in memory use.
189 - cancelling a coro while it itself is cancelling another coro is
190 now supported and working, instead of triggering an assertion.
191 - be a bit more crash-resistant when calling (buggy) on_destroy
192 callbacks (best effort).
193 - move on_destroy into the slf_frame, to allow extension slf
194 functions to have destructors.
195 - get rid if coro refcounting - simply crash in other interpreter
196 threads by nulling the pointers on clone.
197 - simplify warn/die hook handling when loading Coro - the convoluted
198 logic seems to be no longer neccessary.
199 - use libecb instead of our own home-grown gcc hacks.
200 - document alternatives to Coro::LWP. Please use them :)
201 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
202 sigaltstack. Really. wine suffers from it, erlang suffers from it,
203 and it's known since at least 2006.
204
2055.372 Wed Feb 23 06:14:30 CET 2011
206 - apparently mingw doesn't provide a working gettimeofday, try to
207 work around that by relying on Time::HiRes (indirectly brought to
208 my attention by Max Maischein).
209 - fix some portability issues when Time::HiRes was used.
210
2115.371 Mon Feb 21 14:36:08 CET 2011
212 - backport to windows process emulation code again.
213
2145.37 Sat Feb 19 07:49:44 CET 2011
215 - add a big "Coro thread life cycle" section to "man Coro".
216 - try a tentative workaround against the breakage that 5.13 has
217 introduced without depreciation period. sigh.
218 - no longer use Time::HiRes if gettimeofday is available, which
219 saves quite a lot of memory.
220
2215.36 Sun Feb 13 05:33:41 CET 2011
222 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
223 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
224 method call.
225 - undocument Coro::Timer::sleep and obsolete whole module.
226 - optimise Coro::Timer::timeout memory and cpu usage.
227 - slightly updated Coro::Intro for recent changes.
228 - do not initialise PL_dirty anymore.
229
2305.25 Thu Nov 11 01:08:39 CET 2010
231 - try a different approach on netbsd - netbsd 5 finally has marginally
232 working pthreads, but still broken ucontext/sigaltstack.
233 - openbsd 4.8 finally got their act together, Coro works out of the box
234 with asm, setjmp and pthreads (no change, just informational).
235
2365.24 Sat Oct 23 11:27:12 CEST 2010
237 - port to the EV 4.0 API.
238 - work around bugs in mingw32, making strawberry perl work
239 out of the box.
240 - correctly modify Coro::AIO function prototypes
241 so that they reflect the "no optional parameters" rule.
242 - "ported" libcoro to C++.
243
2445.23 Mon May 17 18:50:42 CEST 2010
245 - be more resistant to ordering changes when initialising
246 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
247 Waldorf).
248 - document that perl 5.12 deliberately removed support for cloning.
249
2505.22 Wed Apr 14 03:55:35 CEST 2010
251 - correctly return udnef on errors in Coro::Handle::read/write
252 (testcase by Marc Mims).
253 - convert Coro::Util into a "perl compatibility wrapper" - the functions
254 are less useful now, but are drop-in replacements for existing
255 functions, listing better alternatives in the documentation. This also
256 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
257 with Coro::Util::inet_aton.
258 - do not override $Coro::idle unconditionally in Coro.pm, as other
259 modules could have provided their own idle coro already
260 (for exmaple, Coro::AnyEvent).
261 - fix Coro::Util::gethost* functions.
262 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
263
2645.21 Wed Dec 16 07:19:51 CET 2009
265 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
266 together.
267 - add some examples on how to combine other event loops with Coro in
268 Coro::AnyEvent, and how to run it (and not to block). Seems to be
269 the most common source of confusion.
270 - try to catch people naively blocking in an event callback.
271 - work around the perl filehandle bug issue in conjunction with
272 older common::sense (as indirectly pointed out by ZSystem).
273 - clarify the "not from signal handlers" section.
274
2755.2 Sun Oct 4 14:54:24 CEST 2009
276 - Coro::Storable destroyed the prototypes of the functions it wrapped.
277 - export rouse_cb and rouse_wait by default now.
278 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
279 - new method $state->swap_sv.
280 - added section on "windows process emulation" to the manpage,
281 after a not-so-fruitful (nor-friendly) "discussion" with chip
282 salzenberg (discussion implies arguments, but his only arguments
283 were ad-hominems, one wonders why he started it in the first
284 place). I hope this explains it well enough for him to understand,
285 and maybe well enough for others to understand.
286 - use common::sense everywhere now.
287 - idle callbacks are no longer supported, use idle coros instead.
288 - print a thread listing when a deadlock is detected.
289
2905.17 Sat Aug 22 23:09:31 CEST 2009
291 - work around a bug in the perl debugger causing crashes
292 when running under the debugger by marking _pool_handler as nodebug.
293 - speed up Coro::async considerably.
294 - try some hacks to get netbsd to work "more often" - their broken
295 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
296 - convert Coro to AE 5.0 API.
297
2985.162 Tue Jul 28 04:04:03 CEST 2009
299 - perl 5.8.2 is now minimum requirement.
300 - skip t/19_handle.t on broken windows perls.
301
3025.161 Wed Jul 22 04:47:38 CEST 2009
303 - Coro::AnyEvent::poll could have a different prototype when EV was
304 used as backend (analyzed by Tatsuhiko Miyagawa).
305 - Coro::AnyEvent errornously initialised the event loop when loaded,
306 not on demand.
307 - try to workaround rare */t/01_unblock.t failures.
308
3095.16 Tue Jul 21 01:44:37 CEST 2009
310 - Coro::AnyEvent failed to hook into the event loop
311 when no threads had been readied between detecting
312 the event loop and actually running it.
313 - considerably speed up Coro::Select by taking avdantage
314 of AnyEvent > 4.8 and some other optimisations.
315 - implement paragraph readline mode in Coro::Handle
316 (based on patches by Zsbán Ambrus).
317 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
318 and analyzed by Yasuhiro MATSUMOTO).
319 - clarified libcoro license and copyright.
320 - someone stole my EXTRA_META!!!
321 - implement Coro::Select::patch_pp_sselect and it's brother,
322 for hardcode select overriding.
323
3245.151 Mon Jul 6 05:41:57 CEST 2009
325 - backport to windows process emulation code again (patch by
326 Yasuhiro MATSUMOTO).
327 - slightly update Coro::MakeMaker.
328
3295.15 Tue Jun 30 10:28:06 CEST 2009
330 - deprecate Coro::Socket, document how to get ipv6 support via
331 AnyEvent::Socket instead.
332 - implement signal->wait ($cb) interface, similar to semaphores.
333 - work around SvOK not supporting getmagic, so we have to getmagic
334 to test for undef :/ (reported by Matthias Waldorf).
335 - load Coro::AnyEvent in all modules using AnyEvent.
336 - work around perl corrupting our internal data structures,
337 reported by Tokuhiro Matsuno.
338 - enable per-coroutine real and cpu time gathering
339 (Coro::State::enable_times).
340
3415.14 Wed Jun 24 01:37:48 CEST 2009
342 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
343 as this seems to have been a difficult concept (poll, sleep, idle,
344 idle_upto).
345 - add Coro::AnyEvent::readable/writable functions.
346 - clarify Coro::EV/Event/AnyEvent manpages.
347 - free per-thread global scalars in the thread calling ->cancel, to
348 avoid crashes when $_, $@ etc., are magical but some of those
349 had already been freed.
350 - "unexperimentalise" the callback interface for Coro::Semaphore.
351 - speed up ready queue management/context switching by using a linked
352 list instead of an array (~5-10%).
353 - implement "watch" command in Coro::Debug shells.
354 - for fun, implement time-slicing as an example in the manpage.
355 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
356 Coro::Event, use the normal AnyEvent handling instead of dieing
357 (the same is true for Coro::Handle).
358 - properly document Coro::EV::timed_io_once.
359 - avoid unneccessary ->cancel calls in Coro::Handle.
360 - maybe make it work on mingw32 with win32 backend
361 (based on patch by Yasuhiro Matsumoto).
362
3635.132 Fri May 29 09:00:39 CEST 2009
364 - do not keep a reference to the argument itself in
365 Coro::Semaphore::guard, as it could change later.
366 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
367 should support a prepare callback.
368
3695.131 Mon Mar 16 23:20:37 CET 2009
370 - implement and document Coro->suspend, Coro->resume.
371 - fix Coro::Select implementation to not (often) close
372 the passed file descriptors (testcase provided by pippijn).
373
3745.13 Mon Dec 15 21:51:42 CET 2008
375 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
376 - don't set diehook to C<undef> but instead to NULL, to avoid
377 spurious warnings.
378 - fix a lot of bugs in Coro::SemaphoreSet.
379 - Coro::SemaphoreSet will less often create a semaphore needlessly.
380 - add Coro::SemaphoreSet::count and wait methods.
381 - take advantage of the new Guard module.
382 - deprecate Coro::guard.
383 - try to fix the dreaded 01_unblock tests once more. I hate it when
384 testsuites need more fixing than the code they are supposed to test.
385 - croak in more cases when a required callback isn't resolvable.
386 - fix some minor issues in Coro::State->call/eval.
387 - use current coroutine context instead of a temporary one
388 when temporarily switching to another coroutine.
389 - do not call C-level on_destroy handlers during global destruction,
390 to avoid needless segfaults.
391
3925.12 Sun Dec 7 13:30:38 CET 2008
393 - add default config for MirOS, which seems to be a bug-to-bug
394 compatible fork of openbsd ("world domination by releasing
395 openbsd cvs before the openbsd folks do it" or so :).
396 - free_padlist did destroy the names pad, not good, but didn't
397 seem to bother perl - this could fix issues such as eval ""
398 inside a function called from multiple coroutines.
399 - use a different method to detect destruction time.
400 - be more careful when freeing padlists just before global
401 destruction.
402 - fixed and expanded the call/cc example.
403 - renamed _terminate to _coro_run.
404 - new method Coro::Channel->shutdown.
405 - try pthreads on openbsd <4.4 (broken sigaltstack, will
406 pthreads fare better?).
407 - be less picky about destroying "a" running coroutine.
408
4095.11 Tue Nov 25 21:49:05 CET 2008
410 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
411 working code with failed assertions, introducing more bugs than
412 it fixes, requiring elaborate workarounds :(
413
4145.1 Mon Nov 24 08:54:59 CET 2008
415 - wrote a small introductory tutorial - Coro::Intro.
416 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
417 - Coro::Select did errornously dup the file descriptors
418 and didn't work with all AnyEvent backends.
419 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
420 LWP data transfers.
421 - disassociate c contexts from coro objects - this is agruably more
422 correct, but mostly allows sharing of cctxs between coro and state
423 objects, for added memory savings and speed increases.
424 - bumped $Coro::POOL_RSS up to 32kb by default.
425 - no longer set the optype to OP_CUSTOM, as B::* understandably
426 doesn't like this very much (and we *are* a type of entersub).
427 - implement state cloning, just to prove that call/cc can be done.
428 - automatically load Coro::AnyEvent in Coro::Handle.
429 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
430 do not have this method (and don't need it either).
431 - speed up generic anyevent methods in Coro::Handle by using rouse
432 callbacks.
433 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
434 others. It also makes the debugger happier, as you can trace
435 through the idle threads now.
436 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
437 - eg/event was pretty broken.
438 - better 5.8.6 compatibility.
439
4405.0 Thu Nov 20 10:35:05 CET 2008
441 - NEW ARCHITECTURE: use the latest 4.x version if you experience
442 stability issues.
443 - bump API version to 7 - all dependents must be recompiled.
444 - removed timed_* functions - they were not being used anyways
445 and should be replaced by a more generic mechanism -
446 and were annoying to support anyways :)
447 - removed SemaphoreSet's waiter method - use sem method instead.
448 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
449 - async_pool did free a scalar value twice
450 ("Attempt to unreference...").
451 - fix a longstanding bug where calling terminate on a coro that
452 was waiting for a semaphore that was just becoming available
453 would cause a deadlock (semaphore would get into a state where
454 it was available but waiters were still blocked).
455 - calling throw on a coroutine that is waiting for a semaphore will
456 no longer make it acquire the semaphore (and thus leak a count).
457 - perl's process emulation is now not even theoretically supported
458 anymore.
459 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
460 conversion of callback-style to blocking-style.
461 - new methods $coro->schedule_to and ->cede_to, to specifically
462 schedule or cede to a specific coroutine.
463 - new function Coro::Semaphore::wait.
464 - use named constants in Coro::Channel (Richard Hundt).
465 - directly patch the entersub opcode calling SLF functions (cede,
466 transfer and so on). this does speed up context switching, but
467 more importanly, it frees us from the hardcoded behaviour of
468 entersub, so we might actually be able to return something from
469 those functions and atcually create new ones.
470 - take advantage of __builtin_frame_address on gcc.
471 - expose THX in coroapi (not sure whether this was a wise decision,
472 as "threaded" perls are running at half speed anyways).
473 - implement execute_slf (schedule-like-function) interface that makes
474 it possible to implement schedule-like-functions in XS.
475 - use new SLF interface to massively speed up Coro::EV by roughly a
476 factor of two.
477 - used new SLF interface to massively speed up Coro::Semaphore by a
478 factor of three.
479 - used new SLF interface to speed up Coro::AIO by roughly a factor of
480 four and reduce its memory usage considerably.
481 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
482 for a nice speedup and vastly more correct behaviour. Also implement
483 a new method "sem" to get at the underlying semaphore object.
484 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
485 (in comparison) 20-40% speedup.
486 - used new SLF interface to reimplement Coro::Signal gaining
487 some unknown (because I was too lazy), but certain, speedup, and also
488 making signals reliable for the first time.
489 - used new SLF interface and other optimisations to speed up async_pool
490 by a factor of two. It also doesn't rely on perl's exception mechanism
491 to exit anymore. The overhead for terminating an async_pool, coro over
492 a normal async is now very small.
493 - sped up coroutine creation/destruction by 40%.
494 - forgot to include Coro/libcoro/README in the dist for all these years.
495 - work around a freebsd pthreads bug (manual testcancel is required as
496 pthread_cond_wait isn't a cancellation point on freebsd).
497 - use new rouse functions to speed up and simplify Coro::BDB.
498 - make "prefer perl native functions" work with threaded perls.
499 - condense Coro::Debug ps output, hint at v and w flags.
500 - (libcoro) lots of minor cleanups and portability improvements.
