1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: should explore PerlIO::coroaio (perl leaks like hell). 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: maybe implement a default message channel, very much like Erlang's 4TODO: channel->maxsize(newsize)?
5 actor model (which is cool in a lot of important aspects (failures!), 5TODO: __GCC_HAVE_DWARF2_CFI_ASM
6 but very lacking in others (higher level ipc)). 6TODO: swap_sv, maybe add scope_swap_sv, andallow to unswap by repeat?
7TODO: swap_sv not undone in pool
8TODO: croak when async_pool tries to run canceled thread?
7 9
8TODO: testcancel 10 - avoid segfaulting (or worse) when tracing a canceled thread.
9TODO: guard as SLF - to avoid deadlocks. 11 - the Event module silently broke it's public hook API, causing
10 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 12 failures on perls compiled with -Duselongdouble. Requiring
13 the latest version of Event because I don't know which release
14 changed this (it's not mentioned in the ChangeLog).
15 - allow xs level enterleave hooks via CoroAPI.
11 16
125.0 176.43 Thu Jun 4 15:38:14 CEST 2015
18 - use stability canary.
19 - port to stableperl-5.22.0-1.001.
20 - update libecb.
21
226.42 Wed Feb 11 20:29:52 CET 2015
23 - Coro::SemaphoreSet->try did not actually work (analyzed by
24 SATO Kentaro).
25 - upgrade libecb to be C11 compliant.
26
276.41 Sat Sep 6 22:08:46 CEST 2014
28 - restore portability to perl 5.8.x.
29 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
30 up some memory, but fixes "use feature" and similar modules
31 when used inside a Coro.
32 - allow zero as argument to Coro::Channel to mean the same thing
33 as no argument. this works with older versions as well,
34 but wasn't legal until now.
35 - slightly better c header file detection.
36
376.39 Mon Jun 2 00:00:08 CEST 2014
38 - work around more incompatible changes in 5.20.
39
406.38 Sun Jun 1 21:54:23 CEST 2014
41 - check that perl slots actually have enough space to hold
42 interpreter variables.
43 - untested port to perl 5.19 (64 bit tmps indices) (reported
44 by Andreas König).
45 - croak when cancel is called without a thread context.
46
476.37 Tue Mar 4 13:27:33 CET 2014
48 - *sigh*, removed leftover debugging code from debugging a
49 perl bug, of all things.
50
516.36 Tue Mar 4 07:11:59 CET 2014
52 - semaphores would not clear the destroy hook when interrupted
53 by ->throw, causing segfaults or worse.
54 - ->throw on a thread waiting for a semaphore did not acquire
55 the semaphore, but also didn't wake up other waiters,
56 possibly causing a deadlock.
57 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
58 to report a full stacktrace, which should help find out
59 where the actual call is.
60 - "atomically" destroy data in slf_destroy, because it is
61 the right thing to do, just in case.
62 - disable ecb.h libm dependency, to compile on ancient systems
63 or under adverse conditions.
64
656.33 Mon Nov 18 11:26:27 CET 2013
66 - do not crash when freeing padlists with holes (in 5.18).
67 - tentative SVt_BIND 5.19 port/fix.
68
696.32 Tue Nov 5 15:35:35 CET 2013
70 - use a new algorithm to derive padlists for perl 5.18. The old
71 one could lead to 0-pointer accesses inside perl (reported
72 by Darin McBride).
73
746.31 Thu May 9 07:39:48 CEST 2013
75 - Coro::AIO requests would crash if the thread was ready'd
76 while the request was ongoing.
77
786.29 Wed May 8 02:55:18 CEST 2013
79 - when an on_destroy handler destructs the coro currently being
80 destructed a perl scalar could be accessed after being freed,
81 likely causing a crash.
82
836.28 Wed Mar 6 06:58:02 CET 2013
84 - clean remnants of existing __DIE__ and __WARN__ handlers so
85 they lose their magic and will not cause segfaults later
86 (testcase by Andrey Sagulin).
87 - improved Coro::State documentation a bit.
88 - Coro::Debug::command now flushes the output.
89 - add hack detection code for x32 abi, because the braindead slugs
90 who designed that made it look exactly like x86_64 without
91 providing proper compile time symbols to test for it. as a result,
92 this detection cannot work reliably.
93 - valgrind stack registering was broken.
94 - do not rely on Time::HiRes anymore in Coro::Debug.
95
966.23 Fri Dec 7 23:36:37 CET 2012
97 - use experimental fiber implementation on native windows
98 perls.
99 - use sizeof (void *) as multiplication factor for stack sizes,
100 to accomodate the totally braindamaged microsoft 64 bit "os".
101 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
102 activeperl 5.16 crashes when PerlIO_define_layer is called due
103 to some bug in the perl dll, strawberry perl at least passes
104 the testsuite.
105 - implement Coro::Handle->peeraddr/host/port, for slightly
106 improved compatibility with LWP.
107 - implement 5.17 compatibility by almost blindly applying a
108 good-looking patch by Father Chrysostomos.
109 - move stack management functions into libcoro 3.
110 - libcoro version 3 "released".
111 - support magic values as timed_io_once args.
112 - recommend AnyEvent 7+ or EV 4+, also require EV
113 version 4 or newer for Coro::EV.
114
1156.10 Tue Oct 9 01:14:27 CEST 2012
116 - updated ecb.h, it had a typo that caused it to not compile on many
117 big endian systems (reported by many people).
118 - disable memory fences in ecb.h to improve portability.
119
1206.09 Sat Oct 6 23:25:02 CEST 2012
121 - Coro::EV I/O watchers were not interruptible by exceptions
122 (Coro::State::throw) (testcase by sten).
123 - ->throw now puts threads into the ready queue, as this seems to
124 be expected by existing code, and code that doesn't cope with spurious
125 wakeups needs fixing anyway.
126 - use fd -1 in mmap.
127 - cast I32 to int in error message printf.
128 - warn about broken so-called "hardened" kernels.
129
1306.08 Fri Apr 13 12:05:47 CEST 2012
131 - be more aggressive about exiting like perl does - formerly,
132 exiting from the non-main thread would not execute END blocks.
133
1346.07 Fri Nov 11 21:21:48 CET 2011
135 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
136 - update ecb.h.
137
1386.06 Mon Aug 8 23:59:48 CEST 2011
139 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
140 backend, which is an order of magnitude slower. unfortunately, cygwins
141 pthread implementation isn't very complete either, so allocate the stack
142 twice just to be sure.
143 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
144 in its ithreaded perl - best recompile cygwin and use the 'w'indows
145 backend for much better performance. also disable ithreads for
146 even better performance...).
147
1486.05 Thu Aug 4 21:36:36 CEST 2011
149 - blush, condvar values would not be propagated from send to recv anymore
150 (reported by Chip Salzenberg).
151 - use exponential increase for the readline buffer length in
152 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
153
1546.04 Wed Aug 3 17:15:45 CEST 2011
155 - use even more efficient and more compatible condvars for
156 compatibility to AnyEvent 6.x :)
157 - more inconsequential ecb.h updates.
158
1596.03 Wed Aug 3 11:41:30 CEST 2011
160 - change how Coro patches AnyEvent condvars for compatibility to
161 AnyEvent 6.x.
162 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
163 hasn't been included.
164
1656.02 Wed Jul 13 04:35:19 CEST 2011
166 - "improve portability to Gentoo" - gentoo manages to put perl variables
167 in memory areas that are farther than 2gb apart, which the jit couldn't
168 handle and barfed. now it's just a bit slower on gentoo and similar
169 systems.
170
1716.01 Sun Jul 3 12:31:14 CEST 2011
172 - workarounds are good, but the test for whether pthreads are used
173 was not good. this one should be better.
174 - check differently whether gcc generates cfi instructions itself.
175
1766.0 Wed Jun 29 19:43:35 CEST 2011
177 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
178 destroyed and cleaned up automatically (e.g. async { schedule }).
179 - implement a JIT compiler for part of the thread switch code,
180 which gives a 50% speed improvement on threaded perls, and
181 about 4% on non-threaded perls (so threaded perls now finally
182 reach about half the speed of non-threaded perls).
183 - slightly modernise Coro::Intro, add section about rouse functions.
184 - avoid DEFSV and ERRSV, giving another 10% improvement
185 in thread switching.
186 - Coro::State->is_destroyed is now called is_zombie.
187 - implement a Coro->safe_cancel method that might fail, but
188 cancels in a "safer" way if it succeeds.
189 - add preliminary support for DEBUGGING perls.
190 - get rid of two hash-accesses when initialising a new Coro - this
191 speeds up coro creation by almost a factor of two.
192 - croak when a coro that is being cancelled tries to block
193 (e.g. while executing a guard block), instead of crashing or
194 deadlocking.
195 - use a more robust and also faster method to identify Coro::State
196 objects - speeds up everything a bit.
197 - implement Coro->cancel in XS for a 20% speed improvement, and to
198 be able to implement mutual cancellation.
199 - speed up context switches by a percent or two by more efficiently
200 allocating context stack entries.
201 - implement Coro->join and Coro->on_destroy in XS for a speedup and
202 a reduction in memory use.
203 - cancelling a coro while it itself is cancelling another coro is
204 now supported and working, instead of triggering an assertion.
205 - be a bit more crash-resistant when calling (buggy) on_destroy
206 callbacks (best effort).
207 - move on_destroy into the slf_frame, to allow extension slf
208 functions to have destructors.
209 - get rid if coro refcounting - simply crash in other interpreter
210 threads by nulling the pointers on clone.
211 - simplify warn/die hook handling when loading Coro - the convoluted
212 logic seems to be no longer neccessary.
213 - use libecb instead of our own home-grown gcc hacks.
214 - document alternatives to Coro::LWP. Please use them :)
215 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
216 sigaltstack. Really. wine suffers from it, erlang suffers from it,
217 and it's known since at least 2006.
218
2195.372 Wed Feb 23 06:14:30 CET 2011
220 - apparently mingw doesn't provide a working gettimeofday, try to
221 work around that by relying on Time::HiRes (indirectly brought to
222 my attention by Max Maischein).
223 - fix some portability issues when Time::HiRes was used.
224
2255.371 Mon Feb 21 14:36:08 CET 2011
226 - backport to windows process emulation code again.
227
2285.37 Sat Feb 19 07:49:44 CET 2011
229 - add a big "Coro thread life cycle" section to "man Coro".
230 - try a tentative workaround against the breakage that 5.13 has
231 introduced without depreciation period. sigh.
232 - no longer use Time::HiRes if gettimeofday is available, which
233 saves quite a lot of memory.
234
2355.36 Sun Feb 13 05:33:41 CET 2011
236 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
237 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
238 method call.
239 - undocument Coro::Timer::sleep and obsolete whole module.
240 - optimise Coro::Timer::timeout memory and cpu usage.
241 - slightly updated Coro::Intro for recent changes.
242 - do not initialise PL_dirty anymore.
243
2445.25 Thu Nov 11 01:08:39 CET 2010
245 - try a different approach on netbsd - netbsd 5 finally has marginally
246 working pthreads, but still broken ucontext/sigaltstack.
247 - openbsd 4.8 finally got their act together, Coro works out of the box
248 with asm, setjmp and pthreads (no change, just informational).
249
2505.24 Sat Oct 23 11:27:12 CEST 2010
251 - port to the EV 4.0 API.
252 - work around bugs in mingw32, making strawberry perl work
253 out of the box.
254 - correctly modify Coro::AIO function prototypes
255 so that they reflect the "no optional parameters" rule.
256 - "ported" libcoro to C++.
257
2585.23 Mon May 17 18:50:42 CEST 2010
259 - be more resistant to ordering changes when initialising
260 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
261 Waldorf).
262 - document that perl 5.12 deliberately removed support for cloning.
263
2645.22 Wed Apr 14 03:55:35 CEST 2010
265 - correctly return udnef on errors in Coro::Handle::read/write
266 (testcase by Marc Mims).
267 - convert Coro::Util into a "perl compatibility wrapper" - the functions
268 are less useful now, but are drop-in replacements for existing
269 functions, listing better alternatives in the documentation. This also
270 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
271 with Coro::Util::inet_aton.
272 - do not override $Coro::idle unconditionally in Coro.pm, as other
273 modules could have provided their own idle coro already
274 (for exmaple, Coro::AnyEvent).
275 - fix Coro::Util::gethost* functions.
276 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
277
2785.21 Wed Dec 16 07:19:51 CET 2009
279 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
280 together.
281 - add some examples on how to combine other event loops with Coro in
282 Coro::AnyEvent, and how to run it (and not to block). Seems to be
283 the most common source of confusion.
284 - try to catch people naively blocking in an event callback.
285 - work around the perl filehandle bug issue in conjunction with
286 older common::sense (as indirectly pointed out by ZSystem).
287 - clarify the "not from signal handlers" section.
288
2895.2 Sun Oct 4 14:54:24 CEST 2009
290 - Coro::Storable destroyed the prototypes of the functions it wrapped.
291 - export rouse_cb and rouse_wait by default now.
292 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
293 - new method $state->swap_sv.
294 - added section on "windows process emulation" to the manpage,
295 after a not-so-fruitful (nor-friendly) "discussion" with chip
296 salzenberg (discussion implies arguments, but his only arguments
297 were ad-hominems, one wonders why he started it in the first
298 place). I hope this explains it well enough for him to understand,
299 and maybe well enough for others to understand.
300 - use common::sense everywhere now.
301 - idle callbacks are no longer supported, use idle coros instead.
302 - print a thread listing when a deadlock is detected.
303
3045.17 Sat Aug 22 23:09:31 CEST 2009
305 - work around a bug in the perl debugger causing crashes
306 when running under the debugger by marking _pool_handler as nodebug.
307 - speed up Coro::async considerably.
308 - try some hacks to get netbsd to work "more often" - their broken
309 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
310 - convert Coro to AE 5.0 API.
311
3125.162 Tue Jul 28 04:04:03 CEST 2009
313 - perl 5.8.2 is now minimum requirement.
314 - skip t/19_handle.t on broken windows perls.
315
3165.161 Wed Jul 22 04:47:38 CEST 2009
317 - Coro::AnyEvent::poll could have a different prototype when EV was
318 used as backend (analyzed by Tatsuhiko Miyagawa).
319 - Coro::AnyEvent errornously initialised the event loop when loaded,
320 not on demand.
321 - try to workaround rare */t/01_unblock.t failures.
322
3235.16 Tue Jul 21 01:44:37 CEST 2009
324 - Coro::AnyEvent failed to hook into the event loop
325 when no threads had been readied between detecting
326 the event loop and actually running it.
327 - considerably speed up Coro::Select by taking avdantage
328 of AnyEvent > 4.8 and some other optimisations.
329 - implement paragraph readline mode in Coro::Handle
330 (based on patches by Zsbán Ambrus).
331 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
332 and analyzed by Yasuhiro MATSUMOTO).
333 - clarified libcoro license and copyright.
334 - someone stole my EXTRA_META!!!
335 - implement Coro::Select::patch_pp_sselect and it's brother,
336 for hardcode select overriding.
337
3385.151 Mon Jul 6 05:41:57 CEST 2009
339 - backport to windows process emulation code again (patch by
340 Yasuhiro MATSUMOTO).
341 - slightly update Coro::MakeMaker.
342
3435.15 Tue Jun 30 10:28:06 CEST 2009
344 - deprecate Coro::Socket, document how to get ipv6 support via
345 AnyEvent::Socket instead.
346 - implement signal->wait ($cb) interface, similar to semaphores.
347 - work around SvOK not supporting getmagic, so we have to getmagic
348 to test for undef :/ (reported by Matthias Waldorf).
349 - load Coro::AnyEvent in all modules using AnyEvent.
350 - work around perl corrupting our internal data structures,
351 reported by Tokuhiro Matsuno.
352 - enable per-coroutine real and cpu time gathering
353 (Coro::State::enable_times).
354
3555.14 Wed Jun 24 01:37:48 CEST 2009
356 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
357 as this seems to have been a difficult concept (poll, sleep, idle,
358 idle_upto).
359 - add Coro::AnyEvent::readable/writable functions.
360 - clarify Coro::EV/Event/AnyEvent manpages.
361 - free per-thread global scalars in the thread calling ->cancel, to
362 avoid crashes when $_, $@ etc., are magical but some of those
363 had already been freed.
364 - "unexperimentalise" the callback interface for Coro::Semaphore.
365 - speed up ready queue management/context switching by using a linked
366 list instead of an array (~5-10%).
367 - implement "watch" command in Coro::Debug shells.
368 - for fun, implement time-slicing as an example in the manpage.
369 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
370 Coro::Event, use the normal AnyEvent handling instead of dieing
371 (the same is true for Coro::Handle).
372 - properly document Coro::EV::timed_io_once.
373 - avoid unneccessary ->cancel calls in Coro::Handle.
374 - maybe make it work on mingw32 with win32 backend
375 (based on patch by Yasuhiro Matsumoto).
376
3775.132 Fri May 29 09:00:39 CEST 2009
378 - do not keep a reference to the argument itself in
379 Coro::Semaphore::guard, as it could change later.
380 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
381 should support a prepare callback.
382
3835.131 Mon Mar 16 23:20:37 CET 2009
384 - implement and document Coro->suspend, Coro->resume.
385 - fix Coro::Select implementation to not (often) close
386 the passed file descriptors (testcase provided by pippijn).
387
3885.13 Mon Dec 15 21:51:42 CET 2008
389 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
390 - don't set diehook to C<undef> but instead to NULL, to avoid
391 spurious warnings.
392 - fix a lot of bugs in Coro::SemaphoreSet.
393 - Coro::SemaphoreSet will less often create a semaphore needlessly.
394 - add Coro::SemaphoreSet::count and wait methods.
395 - take advantage of the new Guard module.
396 - deprecate Coro::guard.
397 - try to fix the dreaded 01_unblock tests once more. I hate it when
398 testsuites need more fixing than the code they are supposed to test.
399 - croak in more cases when a required callback isn't resolvable.
400 - fix some minor issues in Coro::State->call/eval.
401 - use current coroutine context instead of a temporary one
402 when temporarily switching to another coroutine.
403 - do not call C-level on_destroy handlers during global destruction,
404 to avoid needless segfaults.
405
4065.12 Sun Dec 7 13:30:38 CET 2008
407 - add default config for MirOS, which seems to be a bug-to-bug
408 compatible fork of openbsd ("world domination by releasing
409 openbsd cvs before the openbsd folks do it" or so :).
410 - free_padlist did destroy the names pad, not good, but didn't
411 seem to bother perl - this could fix issues such as eval ""
412 inside a function called from multiple coroutines.
413 - use a different method to detect destruction time.
414 - be more careful when freeing padlists just before global
415 destruction.
416 - fixed and expanded the call/cc example.
417 - renamed _terminate to _coro_run.
418 - new method Coro::Channel->shutdown.
419 - try pthreads on openbsd <4.4 (broken sigaltstack, will
420 pthreads fare better?).
421 - be less picky about destroying "a" running coroutine.
422
4235.11 Tue Nov 25 21:49:05 CET 2008
424 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
425 working code with failed assertions, introducing more bugs than
426 it fixes, requiring elaborate workarounds :(
427
4285.1 Mon Nov 24 08:54:59 CET 2008
429 - wrote a small introductory tutorial - Coro::Intro.
430 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
431 - Coro::Select did errornously dup the file descriptors
432 and didn't work with all AnyEvent backends.
433 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
434 LWP data transfers.
435 - disassociate c contexts from coro objects - this is agruably more
436 correct, but mostly allows sharing of cctxs between coro and state
437 objects, for added memory savings and speed increases.
438 - bumped $Coro::POOL_RSS up to 32kb by default.
439 - no longer set the optype to OP_CUSTOM, as B::* understandably
440 doesn't like this very much (and we *are* a type of entersub).
441 - implement state cloning, just to prove that call/cc can be done.
442 - automatically load Coro::AnyEvent in Coro::Handle.
443 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
444 do not have this method (and don't need it either).

446 callbacks.
