1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
31.8 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: maybe implement a default message channel, very much like Erlang's
5 actor model (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
7
84.803 Mon Nov 3 17:16:12 CET 2008
9 - use a global asm statement to become independent of gcc otpimisations
10 for CORO_ASM (thanks to pippijn for the idea).
11 - try to workaround yet another broken bsd, this time dragonfly.
12
134.802 Thu Oct 30 10:56:12 CET 2008
14 - support -fno-omit-frame-pointer on x86 with the assembly method.
15 - tune 01_unblock.t tests a bit.
16
174.801 Wed Oct 22 18:33:37 CEST 2008
18 - improve readline speed for very long "lines".
19 - backport to 5.8.8.
20
214.8 Thu Oct 2 13:34:40 CEST 2008
22 - new function Coro::AIO::aio_wait.
23 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
24 - greatly speed up and reduce memory usage of Coro::AIO requests.
25 - implement some other µ-optimisations.
26
274.749 Mon Sep 29 14:40:12 CEST 2008
28 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
29
304.748 Sat Sep 27 14:03:19 CEST 2008
31 - implement, but do not document, PerlIO::cede(granularity).
32 - Coro::Storable forgot to wrap Storable::pstore.
33 - work around the multitude of leaks and memory corruption
34 bugs in PerlIO::via by using our own C-level perliol. As a side
35 effect, Coro::Storable is now much, much, much faster.
36
374.747 Tue Sep 23 01:59:41 CEST 2008
38 - fix a per-cv memleak (one empty array was leaked per
39 code reference).
40 - avoid a crash in coro->call|rss when the coroutine was already
41 destroyed (most noticably when using Coro::Debug::ps :)
42 - also protect *Storable::FILE.
43 - push up default storable granularity to 20ms.
44
454.746 Sun Sep 21 03:22:20 CEST 2008
46 - be more insistent on locking Storable against reentrancy
47 in Coro::Storable.
48 - move swap_def?v and throw to Coro::State, as documented.
49
504.745 Thu Jul 24 00:14:38 CEST 2008
51 - remove debugging code related to MgPV_nolen_const, also try to
52 make it compile with perl 5.8.6 (yes, apple apparently loves
53 outdated software). Reported by John S.
54
554.744 Tue Jul 8 22:06:35 CEST 2008
56 - correctly provide default DIE/WARN handlers as documented.
57 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
58 implementations inside perl work fine for us.
59
604.743 Mon Jun 16 00:21:57 CEST 2008
61 - when using Coro::EV without running EV::loop it could
62 result in busy-waiting for events, this has been fixed.
63 - reduce codesize and improve performance by using EV_DEFAULT_UC.
64
654.742 Sat May 31 14:10:21 CEST 2008
66 - implement a workaround for (some) perl <5.8.8 versions.
67 - require EV 3.3+.
68
694.741 Fri May 30 23:33:09 CEST 2008
70 - tell netbsd how utterly broken their imitation of an OS is
71 and refuse to build by default if pthreads are in use.
72 - switch to "s" method on all bsd's by default, as their ucontext
73 stuff seems just too broken.
74 - fix a bug in Coro::Select.
75
764.74 Thu May 29 20:05:31 CEST 2008
77 - do not test Coro::LWP for lack of dependencies.
78 - do not test Coro::Select for lack of working perls.
79
804.73 Thu May 29 2008
81 - fix a bug in Coro::EV which would cause it to block despite
82 there being runnable coroutines.
83 - sprinkle "no warnings" freely over everything, also suppress
84 warnings for some other modules.
85 - fix typo in WSAEWOULDBLOCK.
86
874.72 Sun May 25 05:14:36 CEST 2008
88 - tweak META.yaml a bit, unfortunately, there is no documented way
89 to have optional dependencies with CPAN. doh :(
90 - avoid running some tests on windows because they would fail due to
91 perl bug (broken fork, broken pipes...).
92 - work around perl on windows bugs where perl returns undocumented
93 error codes for sysread, syswrite etc. by taking advantage
94 of AnyEvent's workaround for that problem.
95 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
96 a common perl implementation bug on windows.
97 - use unix domain sockets in testsuite to work around
98 common perl implementation bugs on widows (they are emulated by
99 tcp sockets on windows. ugh.)
100
1014.71 Sat May 24 20:01:27 CEST 2008
102 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
103 - take advantage of async name resolution of AnyEvent::Util.
104 - work around brutal inet_aton override in Coro::LWP.
105 - take advantage of the readyhook in Coro::EV, for smoother
106 scheduling.
107
1084.7 Sun May 11 00:32:19 CEST 2008
109 - completely reworked the Coro manpage.
110 - added Coro::AnyEvent, generic event loop integration.
111 - implement cancel, ready and kill commands in Coro::Debug.
112 - document find_coro in Coro::Debug.
113 - incompatible change: rename has_stack to has_cctx.
114 - Coro::AIO and Coro::BDB no longer force event model detection,
115 use AnyEvent::AIO and AnyEvent::BDB.
116
1174.6 Sat Apr 26 10:05:14 CEST 2008
118 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
119 by the Coro module. It was a mistake to have it in the first place.
120 - (experimental) support for activestate perl 5.10 (method "w").
121 - (experimental) support for strawberry perl (method "a").
122 - coro_sigelem_set did not return a value although it had to,
123 actual impact unknown.
124
1254.51 Mon Apr 14 13:28:27 CEST 2008
126 - make it compile again on 5.8.
127
1284.50 Thu Apr 10 09:43:17 CEST 2008
129 - I did it twice! (see 4.49).
130
1314.49 Sun Apr 6 21:23:31 CEST 2008
132 - grr, instead of compiling the recent changes on 5.10 only they
133 were compiled on 5.8 only.
134
1354.48 Sun Apr 6 20:36:46 CEST 2008
136 - allow coroutine switches during eval's under 5.10.x, as it seems
137 the parser is a per-interpreter option now, so this is safe
138 (this might fix the odd crashing bug).
139 - drop support for 5.9.x versions: they are dead, jim.
140
1414.47 Sun Apr 6 00:37:52 CEST 2008
142 - force cctx allocation on API calls: we know we need to force one
143 and gcc actually manages to confuse our heuristic nowadays,
144 leading to crashes and worse.
145 - document force_cctx.
146
1474.46 Fri Apr 4 22:05:43 CEST 2008
148 - upgrade libcoro, resulting in pthread-backend (which was only created
149 to fulfill the rules of the programming languages shootout).
150
1514.45 Thu Mar 13 11:55:36 CET 2008
152 - fix a file leaking bug in eg/mhyttpd that would allow
153 downloading of any file (reported by oesi).
154 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
155 (also add testcase).
156 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
157 apparently having loads of fun with that).
158 - implement $state->swap_defsv, ->swap_defav and document ->throw.
159
1604.4 Wed Feb 13 16:44:29 CET 2008
161 - only assume .cfi pseudo isns exist on GNU/Linux.
162 - add get_timed method to Coro::Channels.
163 - fixed Coro::Debug manpage.
164 - perl 5.11 compatbility improvement based on patch by
165 Andreas König.
166
1674.37 Sun Jan 20 11:25:23 CET 2008
168 - soften the check for an active parser for perl 5.10 (avoiding
169 "Coro::State::transfer called while parsing" in many cases).
170
1714.36 Sun Jan 13 10:53:56 CET 2008
172 - reset diehook when terminating from an async_pool as to not
173 trigger any __DIE__ handlers.
174
1754.35 Sun Jan 13 04:14:13 CET 2008
176 - "bt" debug command now displays any exceptions
177 from longmess and also skips the innermost
178 stackframes, giving more useufl output.
179 - allow backtraces in coroutines blocked in Coro::EV,
180 at a <1% speed hit.
181 - handle localising of $SIG{__WARN__} and __DIE__
182 properly (with a proper amount of dirty hacking).
183
1844.34 Sat Dec 22 17:49:53 CET 2007
185 - upgrade to EV version 2.0 API.
186
1874.33 Mon Dec 17 08:36:12 CET 2007
188 - make Coro::AIO etc. loadable in the absence of EV.
189
1904.32 Mon Dec 17 07:46:02 CET 2007
191 - majorly improved Coro::Handle's performance with Coro::EV.
192 - implemented the until now mythical Coro::BDB module.
193 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
194
1954.31 Wed Dec 5 12:32:39 CET 2007
196 - remove warn statement form Coro::Util.
197
1984.3 Tue Dec 4 20:33:14 CET 2007
199 - calls to the idle function could cause stack corruption
200 when the stack changed.
201 - do no longer rely on the presence of EV::DNS if EV is used
202 (because it is gone), but instead take avdantage of EV::ADNS
203 if available.
204 - add ($) prototypes to all functions in Coro::Storable.
205 - use a conventional (safer) idle callback in Coro::EV.
206 - do accept quickly in Coro::Debug to avoid endless loops.
207
2084.22 Fri Nov 30 16:04:04 CET 2007
209 - really use optimised versions for Event and EV in Coro::Util
210 and Coro::Handle.
211
2124.21 Sun Nov 25 10:48:59 CET 2007
213 - fix a spurious memory read.
214 - Coro::EV no longer keeps the eventloop "alive".
215
2164.2 Fri Nov 9 20:47:05 CET 2007
217 - enable/disable tracing from a new coroutine, not a pooled one.
218 - fix a memleak in Coro::Event.
219 - removed killall call from fork_eval.
220 - made sure store_fd is already loaded so that fork_eval
221 does not have to parse autoload in each subprocess.
222 - only use assembly method if -O switch is in $Config{optimize}.
223 - add (optional) Coro::EV module, so far the best event loop module
224 directly supported by Coro.
225 - if the event model is EV, use EV::DNS to resolve
226 stuff in Coro::Util.
227 - don't get confused by multiple event notifications in Coro::Handle.
228 - initial support for EV (libevent interface).
229 - require Event and EV using configure_requires, to force their existance.
230
2314.13 Wed Oct 24 07:26:45 CEST 2007
232 - add Coro::Storable::blocking_thaw.
233 - use a vastly more complicated technique to localise
234 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
235 - use a coroutine for the idle callback Coro::Event,
236 instead of running Event in the current coroutine context.
237 This also catches recursive invocations.
238 - actually report fork errors in gethostbyname and inet_aton.
239
2404.11 Thu Oct 11 02:40:24 CEST 2007
241 - port to threaded perls.
242
2434.1 Thu Oct 11 02:38:16 CEST 2007
244 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
245 be local to each coro (see Coro::State).
246 - incompatible change: for very deep reasons, cede and cede_notself
247 cannot return anything, so nothing will be returned.
248 - possibly bring back 5.10 compatibility (untested).
249 - work around stupid (and wrong) warning on 5.10 :(.
250 - overlay the saved state over the context stack. This saves
251 a few hundred bytes per coroutine on average and also
252 speeds up context switching a bit.
253 - further tune default stack sizes.
254 - (more) correctly calculate stack usage in coro_rss.
255 - Coro::Storable::blocking_* did not properly lock
256 resulting in races between coroutines.
257 - added Coro::Storable::guard.
258 - stopping to trace a coroutine could destroy the cctx of
259 an unrelated coroutine.
260 - explain the relationship between Perl and C coroutines in
261 more detail in Coro::State.
262 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
263 causing a fork per resolve. This also affected Coro::Socket.
264 - switch to a separate stack in $coro->call/eval to avoid
265 invalidating pointers.
266
2674.03 Sat Oct 6 21:24:00 CEST 2007
268 - added Coro::throw method.
269 - minor code cleanups.
270
2714.02 Sat Oct 6 02:36:47 CEST 2007
272 - fix a very minor per-coroutine memleak (a single codereference).
273 - fixed a bug where the currently in-use c context would be freed
274 prematurely (can happen only when programs change the stacksize
275 or use tracing).
276 - tracing can no longer keep a coro alive after it terminated.
277 - do static branch prediction in the common path for gcc. gives
278 about 2-5% speed improvement here.
279
2804.01 Fri Oct 5 22:10:49 CEST 2007
281 - instead of recreating *a* standard output handle we simply
282 use STDOUT, which is faster and hopefully more robust.
283
2844.0 Fri Oct 5 12:56:00 CEST 2007
285 - incompatibly changed Coro::Storable::freeze.
286 - major new feature: added Coro::Debug, for interactive coroutine
287 debugging, tracing and much more.
288 - major bug fix: unbelievable, but true: $_, $/ and many other
289 "saved" variables actually weren't being saved. This has been fixed,
290 of course, while increasing performance while losing all the save
291 flags.
292 - save flags are gone, and all the api functions dealing with them.
293 - added Coro::Semaphore::adjust.
294 - added Coro::Util::fork_eval.
295 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
296 - added Coro::killall.
297 - reduce initial stack sizes to allow for "micro-coroutines".
298 - better async_pool resource management, moved parts of async_pool
299 handling to XS (major speed improvement).
300 - actually croak before modifying important data structures.
301 - refuse to transfer while compiling.
302 - possibly support eval EXPR better now.
303 - enable assembly per default on linux+bsd x86+amd64.
304 - all internal members were renamed _something for easier subclassing.
305 - many minor tweaks.
306
3073.63 Wed May 16 14:10:06 CEST 2007
308 - implement handcoded assembly for x86/amd64 SVR ABI.
309
3103.62 Fri Apr 27 21:36:06 CEST 2007
311 - upgrade libcoro (which might set unwind info correctly).
312 - change default on linux to setjmp/longjmp.
313
3143.61 Thu Apr 19 12:36:18 CEST 2007
315 - Coro::Storable caused an endless loop when thawing invalid
316 pst's sometimes.
317 - use a Semaphore in Coro::Storable, as Storable doesn't
318 seem to be reentrant (although it is documented to
319 be threadsafe...).
320 - fix Coro::Signal to bring back the original unreliable
321 but stateful semantics.
322 - fixed a lot of typos in Coro.pm (patch submitted by David
323 Steinbrunner, which applied flawlessly).
324
3253.6 Sat Apr 14 17:13:31 CEST 2007
326 - added some bugfixes to get eg/myhttpd working again.
327 - added Coro::Storable for often-cede'ing freeze/thaw.
328 - try to do a clean exit when a coroutine calls exit
329 (EXPERIMENTAL).
330 - got rid of indirect call through _coro_init.
331 - updated the partly antique examples in eg/ to
332 work again and be a bit less magic, too.
333 - fixed Coro::Signal semantics to work as documented again.
334
3353.55 Sun Mar 25 01:20:47 CET 2007
336 - add SAVE_DEFFH to save the default filehandle and enable
337 it by default.
338 - finally move socket-operations from Coro::Socket to Coro::Handle
339 to be able to unblock foreign sockets.
340 - add Coro::State::save_also and guarded_save.
341 - add count accessor to Coro::Semaphore.
342 - add Coro::State::cctx_stacksize.
343 - just for the fun of it, do not rely on implicit context,
344 which can dramatically improve performance, but people
345 using windows-process-emulation perls do not care much about
346 performance.
347
3483.51 Sun Mar 4 14:18:04 CET 2007
349 - fixed a problem when you weakened references to Coro::State's
350 (patch by Yuval Kogman).
351
3523.501 Wed Feb 28 12:44:07 CET 2007
353 - rename some global symbols as macosx from hell redefines
354 them without asking.
355
3563.5 Tue Feb 13 20:22:53 CET 2007
357 - do AnyEvent model detection earlier, avoiding problems
358 caused by first using AnyEvent and later Coro::Event.
359 - implement and document Coro::Event event objects.
360 - fix a potential problem in Coro::Event causing crashes.
361 - initialise PL_comppad when creating a new coroutine,
362 avoids crashes on early coro destruction.
363
3643.41 Mon Jan 22 19:19:49 CET 2007
365 - readline on Coro::Handle did not support undefined $/,
366 nor did it deliver partial lines on EOF or error.
367 - implement malloc fallback for stack allocation because
368 stupid broken idiotic OSX has a stupid broken
369 idiotic fits-the-whole-os mmap "implementation" and
370 my dick feels longer if Coro is portable even to
371 obsolete platforms.
372
3733.4 Fri Jan 19 21:52:54 CET 2007
374 - remove t/09_timer.t, as it isn't really testing much
375 but was rather flaky in practise.
376 - async_pool coro would keep arguments and callback alive until
377 it was reused.
378 - cancellation of a coroutine could cause spurious idle calls
379 in cede_notself.
380
3813.3 Sat Jan 6 03:45:00 CET 2007
382 - implement $coro->on_destroy.
383 - Coro::Event blocking semantics have been changed,
384 documented and - hopefully - improved.
385 - fix nice adding, not subtracting, from priority.
386 - fix ->prio and api_is_ready (patch by Mark Hinds).
387 - fixed an assert ("... == prev__cctx->idle_te")
388 that could errronously trigger.
389 - fix various large and small memleaks.
390 - use a (hopefully) more stable cancel implementation
391 that immediately frees the coroutine data.
392 - cede/cede_notself return a status now.
393 - added Coro::guard function.
394 - added a global coroutine pool for jobs (on my machine,
395 I can create and execute 48k simple coros/s with async,
396 and 128k coros with async_pool).
397 - Coro::AIO now uses the coroutine priority as io priority.
398
3993.2 Fri Dec 22 05:07:09 CET 2006
400 - improve portability to slightly older perls.
401 - use cleaner coroutine destruction.
402 - simplify configuration for users.
403 - optionally (unrecommended) prefer perl functions over
404 their coro replacements.
405
4063.11 Tue Dec 5 13:11:24 CET 2006
407 - fixed some bogus assert's, but as perl.h disables assert even
408 without NDEBUG (thank you very much), not too many people should
409 notice (that did include myself). Andreas König noticed, though :)
410 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
411 it. Also noticed by Andreas König :)
412 - save/restore tainted status.
413 - verified to pass the testsuite on my 5.9.5.
414
4153.1 Mon Dec 4 23:03:40 CET 2006
416 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
417 - incompatible change: transfer flags are now per-state.
418 - give a better error message on deadlock.
419 - document Coro::nready.
420 - enhanced testsuite.
421
4223.01 Sun Dec 3 23:47:42 CET 2006
423 - forgot to include Coro::Timer.
424
4253.0 Sun Dec 3 22:57:25 CET 2006
426 - the "FINALLY COMPLETELY STABLE" release (coming soon:
427 the "FAMOUS LAST WORDS" release).
428 - implement a new stack sharing algorithm, which uses a stack
429 pool (size currently hardcoded).
430 - make stack sharing mandatory (it no longer uses a heuristic).
431 - eval/die no longer cause weird problems under heavy use.
432 - Coro::Event could cause livelocks if it was used but
433 no Coro::Event watchers were used.
434 - Coro::Event now uses asynccheck as prepare does not
435 check for changed watchers.
436 - Coro::Event allows multiple waiting coros and will wake up one
437 per event.
438 - Coro::Event should be cleaner and more efficient now.
439 - new utility function Coro::unblock_sub.
440 - document the sad fact that Event is no longer reentrant.
441 - putting a coroutine into the ready queue twice could under
442 some circumstances lead to stack corruption.
443 - minor incompatibility: subclassing Coro::State is supported
444 directly now without going through a _coro_state member.
445 - state/coro switching is much faster now.
446 - very minor optimisations and code/documentation cleanup.
447 - avoid problems due to compiler inlining.
448 - removed timers from Coro::Timer -> use AnyEvent instead.
449 - replaced Coro::idle coroutine by (cleaner) idle handler.
450 - updated to newest libcoro.
451 - implement enhanced support for valgrind.
452 - implement is_ready and return value for ready.
453 - removed Coro::Cont, it was a misnomer (it's generators),
454 and it was somewhat annoying to get it right. Will come back
455 if somebody asks for it :)
456 - many ->wait methods and Coro::Event could return
457 spuriously without the event having happened.
458
4592.5 Tue Nov 7 12:22:33 CET 2006
460 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
461 use AnyEvent, moved them to Coro/.
462 - added Coro::LWP which contains all the uglyness required to
463 make LWP non-blocking.
464 - should work with perl 5.9.x now (Andreas König made me do it).
465 - fixed another bug in Coro::Select when the timeout was undef.
466 - reuse PL_start_env for all coros, saves some memory per coroutine.
467 - manage PL_top_env differently, hopefully to avoid panic: top_env.
468 - timeout argument was not properly used in Coro::Socket.
469 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
470 - emulate undocumented(!) functionality of IO::Socket required
471 by LWP(!!).
472 - updated eg/lwp to work with newer lwp's.
473 - remove "FATAL: uncaught exception" prefix. Coroutines that die
474 kill the whole process, just as exceptions in the main "coroutine"
475 did already.

4772.1 Wed Nov 1 23:01:13 CET 2006
478 - fix a long-standing bug in Coro::Select where select with
479 zero timeout would instead change the current default filehandle.
480 - use a simpler and hopefully more robust way to clone padlists
481 (uses less memory and a perl function instead of our own).
482 - coro can now create a stack guard area on many architectures.
483 - Coro::AIO properly reexports additional functions from IO::AIO.
484 - updated libcoro with a workaround for OS X,
485 pach and testing by Michael Schwern.
