1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
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
8 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
9 - Coro::Select did errornously dup the file descriptors
10 and didn't work with all AnyEvent backends.
11
125.0 Thu Nov 20 10:35:05 CET 2008
13 - NEW ARCHITECTURE: use the latest 4.x version if you experience
14 stability issues.
15 - bump API version to 7 - all dependents must be recompiled.
16 - removed timed_* functions - they were not being used anyways
17 and should be replaced by a more generic mechanism -
18 and were annoying to support anyways :)
19 - removed SemaphoreSet's waiter method - use sem method instead.
20 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
21 - async_pool did free a scalar value twice
22 ("Attempt to unreference...").
23 - fix a longstanding bug where calling terminate on a coro that
24 was waiting for a semaphore that was just becoming available
25 would cause a deadlock (semaphore would get into a state where
26 it was available but waiters were still blocked).
27 - calling throw on a coroutine that is waiting for a semaphore will
28 no longer make it acquire the semaphore (and thus leak a count).
29 - perl's process emulation is now not even theoretically supported
30 anymore.
31 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
32 conversion of callback-style to blocking-style.
33 - new methods $coro->schedule_to and ->cede_to, to specifically
34 schedule or cede to a specific coroutine.
35 - new function Coro::Semaphore::wait.
36 - use named constants in Coro::Channel (Richard Hundt).
37 - directly patch the entersub opcode calling SLF functions (cede,
38 transfer and so on). this does speed up context switching, but
39 more importanly, it frees us from the hardcoded behaviour of
40 entersub, so we might actually be able to return something from
41 those functions and atcually create new ones.
42 - take advantage of __builtin_frame_address on gcc.
43 - expose THX in coroapi (not sure whether this was a wise decision,
44 as "threaded" perls are running at half speed anyways).
45 - implement execute_slf (schedule-like-function) interface that makes
46 it possible to implement schedule-like-functions in XS.
47 - use new SLF interface to massively speed up Coro::EV by roughly a
48 factor of two.
49 - used new SLF interface to massively speed up Coro::Semaphore by a
50 factor of three.
51 - used new SLF interface to speed up Coro::AIO by roughly a factor of
52 four and reduce its memory usage considerably.
53 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
54 for a nice speedup and vastly more correct behaviour. Also implement
55 a new method "sem" to get at the underlying semaphore object.
56 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
57 (in comparison) 20-40% speedup.
58 - used new SLF interface to reimplement Coro::Signal gaining
59 some unknown (because I was too lazy), but certain, speedup, and also
60 making signals reliable for the first time.
61 - used new SLF interface and other optimisations to speed up async_pool
62 by a factor of two. It also doesn't rely on perl's exception mechanism
63 to exit anymore. The overhead for terminating an async_pool, coro over
64 a normal async is now very small.
65 - sped up coroutine creation/destruction by 40%.
66 - forgot to include Coro/libcoro/README in the dist for all these years.
67 - work around a freebsd pthreads bug (manual testcancel is required as
68 pthread_cond_wait isn't a cancellation point on freebsd).
69 - use new rouse functions to speed up and simplify Coro::BDB.
70 - make "prefer perl native functions" work with threaded perls.
71 - condense Coro::Debug ps output, hint at v and w flags.
72 - (libcoro) lots of minor cleanups and portability improvements.
73
744.914 Wed Nov 19 12:54:18 CET 2008
75 - fix a disastrous bug in the readline optimisation
76 introduced in 4.801.
77
784.913 Sat Nov 15 07:58:28 CET 2008
79 - async_pool did free a scalar value twice
80 ("Attempt to unreference...").
81
824.912 Thu Nov 13 18:31:23 CET 2008
83 - minor cleanups.
84 - use much larger stacks on linux and perl < 5.8.8.
85 - Coro::Debug::new_unix_server did not unlink the socket
86 when destroyed.
87
884.911 Tue Nov 11 04:26:17 CET 2008
89 - "port" to threaded perls.
90
914.91 Mon Nov 10 05:36:38 CET 2008
92 - the ->throw exception object no longer leaks.
93 - creating a new cctx leaked a scopestack entry (memleak).
94 - new coroutines didn't get created with a zero flags field
95 (unknown impact).
96 - calling ->throw on a not-yet-started coroutine should now work
97 instead of being ignored.
98 - ->throw is now supported on Coro::State objects.
99 - clean up cctx creation code a bit.
100 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
101
1024.9 Sat Nov 8 17:45:27 CET 2008
103 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
104 - (libcoro) no longer leak threads in the experimental pthread backend,
105 also speed it up considerably.
106 - (libcoro) do not rely on makecontext passing void *'s unscathed.
107 - fix compiletime dependencies on libcoro in the Makefile.
108 - cctx_count wasn't always updated properly.
109 - Coro::State::cctx_stacksize wasn't applied correctly.
110 - new function Coro::State::cctx_max_idle.
111 - the default max number of idle C contexts is now 4.
112 - (libcoro) try harder to get _setjmp/_longjmp.
113 - (libcoro) cleanup and extend the libcoro API to officially
114 allow the creation of empty source contexts.
115 - very experimental workaround for the totally broken netbsd platform.
116 - tried to hack around openbsd bugs.
117
1184.804 Wed Nov 5 16:36:00 CET 2008
119 - Coro::Debug::new_unix_server would not create a non-blocking listening
120 socket, sometimes causing freezes.
121 - (libcoro) fix misaligned stack points for setjmp and assembly
122 methods, which can cause crashes on x86/x86_64 with a sufficiently
123 aggressive compiler.
124 - new function: Coro::Debug::new_tcp_server.
125 - move ->throw into the Coro class because it only works on coro objects.
126
1274.803 Mon Nov 3 17:16:12 CET 2008
128 - (libcoro) use a global asm statement to become independent of gcc
129 otpimisations for CORO_ASM (thanks to pippijn for the idea).
130 - try to workaround yet another broken bsd, this time dragonfly.
131
1324.802 Thu Oct 30 10:56:12 CET 2008
133 - support -fno-omit-frame-pointer on x86 with the assembly method.
134 - tune 01_unblock.t tests a bit.
135
1364.801 Wed Oct 22 18:33:37 CEST 2008
137 - improve readline speed for very long "lines".
138 - backport to 5.8.8.
139
1404.8 Thu Oct 2 13:34:40 CEST 2008
141 - new function Coro::AIO::aio_wait.
142 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
143 - greatly speed up and reduce memory usage of Coro::AIO requests.
144 - implement some other µ-optimisations.
145
1464.749 Mon Sep 29 14:40:12 CEST 2008
147 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
148
1494.748 Sat Sep 27 14:03:19 CEST 2008
150 - implement, but do not document, PerlIO::cede(granularity).
151 - Coro::Storable forgot to wrap Storable::pstore.
152 - work around the multitude of leaks and memory corruption
153 bugs in PerlIO::via by using our own C-level perliol. As a side
154 effect, Coro::Storable is now much, much, much faster.
155
1564.747 Tue Sep 23 01:59:41 CEST 2008
157 - fix a per-cv memleak (one empty array was leaked per
158 code reference).
159 - avoid a crash in coro->call|rss when the coroutine was already
160 destroyed (most noticably when using Coro::Debug::ps :)
161 - also protect *Storable::FILE.
162 - push up default storable granularity to 20ms.
163
1644.746 Sun Sep 21 03:22:20 CEST 2008
165 - be more insistent on locking Storable against reentrancy
166 in Coro::Storable.
167 - move swap_def?v and throw to Coro::State, as documented.
168
1694.745 Thu Jul 24 00:14:38 CEST 2008
170 - remove debugging code related to MgPV_nolen_const, also try to
171 make it compile with perl 5.8.6 (yes, apple apparently loves
172 outdated software). Reported by John S.
173
1744.744 Tue Jul 8 22:06:35 CEST 2008
175 - correctly provide default DIE/WARN handlers as documented.
176 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
177 implementations inside perl work fine for us.
178
1794.743 Mon Jun 16 00:21:57 CEST 2008
180 - when using Coro::EV without running EV::loop it could
181 result in busy-waiting for events, this has been fixed.
182 - reduce codesize and improve performance by using EV_DEFAULT_UC.
183
1844.742 Sat May 31 14:10:21 CEST 2008
185 - implement a workaround for (some) perl <5.8.8 versions.
186 - require EV 3.3+.
187
1884.741 Fri May 30 23:33:09 CEST 2008
189 - tell netbsd how utterly broken their imitation of an OS is
190 and refuse to build by default if pthreads are in use.
191 - switch to "s" method on all bsd's by default, as their ucontext
192 stuff seems just too broken.
193 - fix a bug in Coro::Select.
194
1954.74 Thu May 29 20:05:31 CEST 2008
196 - do not test Coro::LWP for lack of dependencies.
197 - do not test Coro::Select for lack of working perls.
198
1994.73 Thu May 29 2008
200 - fix a bug in Coro::EV which would cause it to block despite
201 there being runnable coroutines.
202 - sprinkle "no warnings" freely over everything, also suppress
203 warnings for some other modules.
204 - fix typo in WSAEWOULDBLOCK.
205
2064.72 Sun May 25 05:14:36 CEST 2008
207 - tweak META.yaml a bit, unfortunately, there is no documented way
208 to have optional dependencies with CPAN. doh :(
209 - avoid running some tests on windows because they would fail due to
210 perl bug (broken fork, broken pipes...).
211 - work around perl on windows bugs where perl returns undocumented
212 error codes for sysread, syswrite etc. by taking advantage
213 of AnyEvent's workaround for that problem.
214 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
215 a common perl implementation bug on windows.
216 - use unix domain sockets in testsuite to work around
217 common perl implementation bugs on widows (they are emulated by
218 tcp sockets on windows. ugh.)
219
2204.71 Sat May 24 20:01:27 CEST 2008
221 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
222 - take advantage of async name resolution of AnyEvent::Util.
223 - work around brutal inet_aton override in Coro::LWP.
224 - take advantage of the readyhook in Coro::EV, for smoother
225 scheduling.
226
2274.7 Sun May 11 00:32:19 CEST 2008
228 - completely reworked the Coro manpage.
229 - added Coro::AnyEvent, generic event loop integration.
230 - implement cancel, ready and kill commands in Coro::Debug.
231 - document find_coro in Coro::Debug.
232 - incompatible change: rename has_stack to has_cctx.
233 - Coro::AIO and Coro::BDB no longer force event model detection,
234 use AnyEvent::AIO and AnyEvent::BDB.
235
2364.6 Sat Apr 26 10:05:14 CEST 2008
237 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
238 by the Coro module. It was a mistake to have it in the first place.
239 - (experimental) support for activestate perl 5.10 (method "w").
240 - (experimental) support for strawberry perl (method "a").
241 - coro_sigelem_set did not return a value although it had to,
242 actual impact unknown.
243
2444.51 Mon Apr 14 13:28:27 CEST 2008
245 - make it compile again on 5.8.
246
2474.50 Thu Apr 10 09:43:17 CEST 2008
248 - I did it twice! (see 4.49).
249
2504.49 Sun Apr 6 21:23:31 CEST 2008
251 - grr, instead of compiling the recent changes on 5.10 only they
252 were compiled on 5.8 only.
253
2544.48 Sun Apr 6 20:36:46 CEST 2008
255 - allow coroutine switches during eval's under 5.10.x, as it seems
256 the parser is a per-interpreter option now, so this is safe
257 (this might fix the odd crashing bug).
258 - drop support for 5.9.x versions: they are dead, jim.
259
2604.47 Sun Apr 6 00:37:52 CEST 2008
261 - force cctx allocation on API calls: we know we need to force one
262 and gcc actually manages to confuse our heuristic nowadays,
263 leading to crashes and worse.
264 - document force_cctx.
265
2664.46 Fri Apr 4 22:05:43 CEST 2008
267 - upgrade libcoro, resulting in pthread-backend (which was only created
268 to fulfill the rules of the programming languages shootout).
269
2704.45 Thu Mar 13 11:55:36 CET 2008
271 - fix a file leaking bug in eg/mhyttpd that would allow
272 downloading of any file (reported by oesi).
273 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
274 (also add testcase).
275 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
276 apparently having loads of fun with that).
277 - implement $state->swap_defsv, ->swap_defav and document ->throw.
278
2794.4 Wed Feb 13 16:44:29 CET 2008
280 - only assume .cfi pseudo isns exist on GNU/Linux.
281 - add get_timed method to Coro::Channels.
282 - fixed Coro::Debug manpage.
283 - perl 5.11 compatbility improvement based on patch by
284 Andreas König.
285
2864.37 Sun Jan 20 11:25:23 CET 2008
287 - soften the check for an active parser for perl 5.10 (avoiding
288 "Coro::State::transfer called while parsing" in many cases).
289
2904.36 Sun Jan 13 10:53:56 CET 2008
291 - reset diehook when terminating from an async_pool as to not
292 trigger any __DIE__ handlers.
293
2944.35 Sun Jan 13 04:14:13 CET 2008
295 - "bt" debug command now displays any exceptions
296 from longmess and also skips the innermost
297 stackframes, giving more useufl output.
298 - allow backtraces in coroutines blocked in Coro::EV,
299 at a <1% speed hit.
300 - handle localising of $SIG{__WARN__} and __DIE__
301 properly (with a proper amount of dirty hacking).
302
3034.34 Sat Dec 22 17:49:53 CET 2007
304 - upgrade to EV version 2.0 API.
305
3064.33 Mon Dec 17 08:36:12 CET 2007
307 - make Coro::AIO etc. loadable in the absence of EV.
308
3094.32 Mon Dec 17 07:46:02 CET 2007
310 - majorly improved Coro::Handle's performance with Coro::EV.
311 - implemented the until now mythical Coro::BDB module.
312 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
313
3144.31 Wed Dec 5 12:32:39 CET 2007
315 - remove warn statement form Coro::Util.
316
3174.3 Tue Dec 4 20:33:14 CET 2007
318 - calls to the idle function could cause stack corruption
319 when the stack changed.
320 - do no longer rely on the presence of EV::DNS if EV is used
321 (because it is gone), but instead take avdantage of EV::ADNS
322 if available.
323 - add ($) prototypes to all functions in Coro::Storable.
324 - use a conventional (safer) idle callback in Coro::EV.
325 - do accept quickly in Coro::Debug to avoid endless loops.
326
3274.22 Fri Nov 30 16:04:04 CET 2007
328 - really use optimised versions for Event and EV in Coro::Util
329 and Coro::Handle.
330
3314.21 Sun Nov 25 10:48:59 CET 2007
332 - fix a spurious memory read.
333 - Coro::EV no longer keeps the eventloop "alive".
334
3354.2 Fri Nov 9 20:47:05 CET 2007
336 - enable/disable tracing from a new coroutine, not a pooled one.
337 - fix a memleak in Coro::Event.
338 - removed killall call from fork_eval.
339 - made sure store_fd is already loaded so that fork_eval
340 does not have to parse autoload in each subprocess.
341 - only use assembly method if -O switch is in $Config{optimize}.
342 - add (optional) Coro::EV module, so far the best event loop module
343 directly supported by Coro.
344 - if the event model is EV, use EV::DNS to resolve
345 stuff in Coro::Util.
346 - don't get confused by multiple event notifications in Coro::Handle.
347 - initial support for EV (libevent interface).
348 - require Event and EV using configure_requires, to force their existance.
349
3504.13 Wed Oct 24 07:26:45 CEST 2007
351 - add Coro::Storable::blocking_thaw.
352 - use a vastly more complicated technique to localise
353 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
354 - use a coroutine for the idle callback Coro::Event,
355 instead of running Event in the current coroutine context.
356 This also catches recursive invocations.
357 - actually report fork errors in gethostbyname and inet_aton.
358
3594.11 Thu Oct 11 02:40:24 CEST 2007
360 - port to threaded perls.
361
3624.1 Thu Oct 11 02:38:16 CEST 2007
363 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
364 be local to each coro (see Coro::State).
365 - incompatible change: for very deep reasons, cede and cede_notself
366 cannot return anything, so nothing will be returned.
367 - possibly bring back 5.10 compatibility (untested).
368 - work around stupid (and wrong) warning on 5.10 :(.
369 - overlay the saved state over the context stack. This saves
370 a few hundred bytes per coroutine on average and also
371 speeds up context switching a bit.
372 - further tune default stack sizes.
373 - (more) correctly calculate stack usage in coro_rss.
374 - Coro::Storable::blocking_* did not properly lock
375 resulting in races between coroutines.
376 - added Coro::Storable::guard.
377 - stopping to trace a coroutine could destroy the cctx of
378 an unrelated coroutine.
379 - explain the relationship between Perl and C coroutines in
380 more detail in Coro::State.
381 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
382 causing a fork per resolve. This also affected Coro::Socket.
383 - switch to a separate stack in $coro->call/eval to avoid
384 invalidating pointers.
385
3864.03 Sat Oct 6 21:24:00 CEST 2007
387 - added Coro::throw method.
388 - minor code cleanups.
389
3904.02 Sat Oct 6 02:36:47 CEST 2007
391 - fix a very minor per-coroutine memleak (a single codereference).
392 - fixed a bug where the currently in-use c context would be freed
393 prematurely (can happen only when programs change the stacksize
394 or use tracing).
395 - tracing can no longer keep a coro alive after it terminated.
396 - do static branch prediction in the common path for gcc. gives
397 about 2-5% speed improvement here.
398
3994.01 Fri Oct 5 22:10:49 CEST 2007
400 - instead of recreating *a* standard output handle we simply
401 use STDOUT, which is faster and hopefully more robust.
402
4034.0 Fri Oct 5 12:56:00 CEST 2007
404 - incompatibly changed Coro::Storable::freeze.
405 - major new feature: added Coro::Debug, for interactive coroutine
406 debugging, tracing and much more.
407 - major bug fix: unbelievable, but true: $_, $/ and many other
408 "saved" variables actually weren't being saved. This has been fixed,
409 of course, while increasing performance while losing all the save
410 flags.
411 - save flags are gone, and all the api functions dealing with them.
412 - added Coro::Semaphore::adjust.
413 - added Coro::Util::fork_eval.
414 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
415 - added Coro::killall.
416 - reduce initial stack sizes to allow for "micro-coroutines".
417 - better async_pool resource management, moved parts of async_pool
418 handling to XS (major speed improvement).
419 - actually croak before modifying important data structures.
420 - refuse to transfer while compiling.
421 - possibly support eval EXPR better now.
422 - enable assembly per default on linux+bsd x86+amd64.
423 - all internal members were renamed _something for easier subclassing.
424 - many minor tweaks.
425
4263.63 Wed May 16 14:10:06 CEST 2007
427 - implement handcoded assembly for x86/amd64 SVR ABI.
428
4293.62 Fri Apr 27 21:36:06 CEST 2007
430 - upgrade libcoro (which might set unwind info correctly).
431 - change default on linux to setjmp/longjmp.
432
4333.61 Thu Apr 19 12:36:18 CEST 2007
434 - Coro::Storable caused an endless loop when thawing invalid
435 pst's sometimes.
436 - use a Semaphore in Coro::Storable, as Storable doesn't
437 seem to be reentrant (although it is documented to
438 be threadsafe...).
439 - fix Coro::Signal to bring back the original unreliable
440 but stateful semantics.
441 - fixed a lot of typos in Coro.pm (patch submitted by David
442 Steinbrunner, which applied flawlessly).
443
4443.6 Sat Apr 14 17:13:31 CEST 2007
445 - added some bugfixes to get eg/myhttpd working again.
446 - added Coro::Storable for often-cede'ing freeze/thaw.
447 - try to do a clean exit when a coroutine calls exit
448 (EXPERIMENTAL).
449 - got rid of indirect call through _coro_init.
450 - updated the partly antique examples in eg/ to
451 work again and be a bit less magic, too.
452 - fixed Coro::Signal semantics to work as documented again.

4543.55 Sun Mar 25 01:20:47 CET 2007
455 - add SAVE_DEFFH to save the default filehandle and enable
456 it by default.
457 - finally move socket-operations from Coro::Socket to Coro::Handle
458 to be able to unblock foreign sockets.
459 - add Coro::State::save_also and guarded_save.
460 - add count accessor to Coro::Semaphore.
461 - add Coro::State::cctx_stacksize.
462 - just for the fun of it, do not rely on implicit context,
463 which can dramatically improve performance, but people
464 using windows-process-emulation perls do not care much about
465 performance.
466
4673.51 Sun Mar 4 14:18:04 CET 2007
468 - fixed a problem when you weakened references to Coro::State's
469 (patch by Yuval Kogman).
470
4713.501 Wed Feb 28 12:44:07 CET 2007
472 - rename some global symbols as macosx from hell redefines
473 them without asking.
474
4753.5 Tue Feb 13 20:22:53 CET 2007
476 - do AnyEvent model detection earlier, avoiding problems
477 caused by first using AnyEvent and later Coro::Event.
478 - implement and document Coro::Event event objects.
479 - fix a potential problem in Coro::Event causing crashes.
480 - initialise PL_comppad when creating a new coroutine,
481 avoids crashes on early coro destruction.
482
4833.41 Mon Jan 22 19:19:49 CET 2007
484 - readline on Coro::Handle did not support undefined $/,
485 nor did it deliver partial lines on EOF or error.
486 - implement malloc fallback for stack allocation because
487 stupid broken idiotic OSX has a stupid broken
488 idiotic fits-the-whole-os mmap "implementation" and
489 my dick feels longer if Coro is portable even to
490 obsolete platforms.
491
4923.4 Fri Jan 19 21:52:54 CET 2007
493 - remove t/09_timer.t, as it isn't really testing much
494 but was rather flaky in practise.
495 - async_pool coro would keep arguments and callback alive until
496 it was reused.
497 - cancellation of a coroutine could cause spurious idle calls
498 in cede_notself.
499
5003.3 Sat Jan 6 03:45:00 CET 2007
501 - implement $coro->on_destroy.
502 - Coro::Event blocking semantics have been changed,
503 documented and - hopefully - improved.
504 - fix nice adding, not subtracting, from priority.
505 - fix ->prio and api_is_ready (patch by Mark Hinds).
506 - fixed an assert ("... == prev__cctx->idle_te")
507 that could errronously trigger.
508 - fix various large and small memleaks.
509 - use a (hopefully) more stable cancel implementation
510 that immediately frees the coroutine data.
511 - cede/cede_notself return a status now.
512 - added Coro::guard function.
513 - added a global coroutine pool for jobs (on my machine,
514 I can create and execute 48k simple coros/s with async,
515 and 128k coros with async_pool).
516 - Coro::AIO now uses the coroutine priority as io priority.
517
5183.2 Fri Dec 22 05:07:09 CET 2006
519 - improve portability to slightly older perls.
520 - use cleaner coroutine destruction.
521 - simplify configuration for users.
522 - optionally (unrecommended) prefer perl functions over
523 their coro replacements.
524
5253.11 Tue Dec 5 13:11:24 CET 2006
526 - fixed some bogus assert's, but as perl.h disables assert even
527 without NDEBUG (thank you very much), not too many people should
528 notice (that did include myself). Andreas König noticed, though :)
529 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
530 it. Also noticed by Andreas König :)
531 - save/restore tainted status.
532 - verified to pass the testsuite on my 5.9.5.
533
5343.1 Mon Dec 4 23:03:40 CET 2006
535 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
536 - incompatible change: transfer flags are now per-state.
537 - give a better error message on deadlock.
538 - document Coro::nready.
539 - enhanced testsuite.
540
5413.01 Sun Dec 3 23:47:42 CET 2006
542 - forgot to include Coro::Timer.
543
5443.0 Sun Dec 3 22:57:25 CET 2006
545 - the "FINALLY COMPLETELY STABLE" release (coming soon:
546 the "FAMOUS LAST WORDS" release).
547 - implement a new stack sharing algorithm, which uses a stack
548 pool (size currently hardcoded).
549 - make stack sharing mandatory (it no longer uses a heuristic).
550 - eval/die no longer cause weird problems under heavy use.
551 - Coro::Event could cause livelocks if it was used but
552 no Coro::Event watchers were used.
553 - Coro::Event now uses asynccheck as prepare does not
554 check for changed watchers.
555 - Coro::Event allows multiple waiting coros and will wake up one
556 per event.
557 - Coro::Event should be cleaner and more efficient now.
558 - new utility function Coro::unblock_sub.
559 - document the sad fact that Event is no longer reentrant.
560 - putting a coroutine into the ready queue twice could under
561 some circumstances lead to stack corruption.
562 - minor incompatibility: subclassing Coro::State is supported
563 directly now without going through a _coro_state member.
564 - state/coro switching is much faster now.
565 - very minor optimisations and code/documentation cleanup.
566 - avoid problems due to compiler inlining.
567 - removed timers from Coro::Timer -> use AnyEvent instead.
568 - replaced Coro::idle coroutine by (cleaner) idle handler.
569 - updated to newest libcoro.
570 - implement enhanced support for valgrind.
571 - implement is_ready and return value for ready.
572 - removed Coro::Cont, it was a misnomer (it's generators),
573 and it was somewhat annoying to get it right. Will come back
574 if somebody asks for it :)
575 - many ->wait methods and Coro::Event could return
576 spuriously without the event having happened.
577
5782.5 Tue Nov 7 12:22:33 CET 2006
579 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
580 use AnyEvent, moved them to Coro/.
581 - added Coro::LWP which contains all the uglyness required to
582 make LWP non-blocking.
583 - should work with perl 5.9.x now (Andreas König made me do it).
584 - fixed another bug in Coro::Select when the timeout was undef.
585 - reuse PL_start_env for all coros, saves some memory per coroutine.
586 - manage PL_top_env differently, hopefully to avoid panic: top_env.
587 - timeout argument was not properly used in Coro::Socket.
588 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
589 - emulate undocumented(!) functionality of IO::Socket required
590 by LWP(!!).
591 - updated eg/lwp to work with newer lwp's.
592 - remove "FATAL: uncaught exception" prefix. Coroutines that die
593 kill the whole process, just as exceptions in the main "coroutine"
594 did already.
595
5962.1 Wed Nov 1 23:01:13 CET 2006
597 - fix a long-standing bug in Coro::Select where select with
598 zero timeout would instead change the current default filehandle.
599 - use a simpler and hopefully more robust way to clone padlists
600 (uses less memory and a perl function instead of our own).
601 - coro can now create a stack guard area on many architectures.
602 - Coro::AIO properly reexports additional functions from IO::AIO.
603 - updated libcoro with a workaround for OS X,
604 pach and testing by Michael Schwern.
605
6062.0 Tue Oct 24 05:47:17 CEST 2006
607 - support additional aio requests in Coro::AIO.
608
6091.9 (never properly released due to a glitch)
610
6111.8 Thu Feb 2 00:59:06 CET 2006
612 - applied suggested patch by SAMV to avoid problems during stupid
613 mark & sweep gc run.
614 - applied patch by Scott Walters for 5.9.3 compatibility.
615
6161.7 Tue Dec 27 01:41:58 CET 2005
617 - added Coro::AIO, a thin wrapper around IO::AIO.
618 - improved Makefile.PL explanations.
619
6201.6 Mon Dec 12 21:30:05 CET 2005
621 - additionally save PM_curpm might fix as-of-yet
622 unseen problems with regex matches being attributed to the
623 wrong package.
624 - add t/10_bugs.t, which currently checks against imho broken
625 perls that use 0.26MB of stack space per Perl_magic_get
626 invocation (newer linuxes) as opposed to the 0.0002MB perl
627 normally uses.
628 - make stacksize configurable for the ultimate debian experience.
629
6301.51 Mon Dec 12 18:48:36 CET 2005
631 - remove debugging warn() accidentally left in Coro::Select.
632
6331.5 Tue Nov 29 13:32:44 CET 2005
634 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
635 - fix Coro::Select 'select'.
636 - strict'ify some modules.
637 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
638 - use XSLoader in selected modules.
639 - remove some 5.6 compatibility cruft.
640
6411.4 Tue Sep 6 00:11:05 CEST 2005
642 - libcoro did not take into account the trampoline on amd64,
643 when 'l'inux method was used.
644
6451.31 Tue Aug 30 23:31:33 CEST 2005
646 - some portability fixes/workarounds.
647
31.3 Sat Aug 20 03:08:56 CEST 2005 6481.3 Sat Aug 20 03:08:56 CEST 2005
649 - no code changes. module seems to work fine.
4 - improve Coro::State docs, remove reference to nonexisting 650 - improve Coro::State docs, remove reference to nonexisting
5 Coro::State::flush method. 651 Coro::State::flush method.
6 - no longer autodetect windows, present it as an option instead. 652 - no longer autodetect windows, present it as an option instead.
