1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
30.45 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
85.0
9 - NEW ARCHITECTURE: use 4.912 for the stable version.
10 - bump API version to 7 - all dependents must be recompiled.
11 - directly patch the entersub opcode calling ssl functions (cede,
12 transfer and so on). this does speed up context switching by
13 up to 10%. More importanly, it frees us from the hardcoded
14 behaviour of entersub, so we might actually be able to return
15 something from those functions.
16 - take advanatge of __builtin_frame_address on gcc.
17 - expose THX in coroapi (not sure whether this was a wise decision).
18
194.912 Thu Nov 13 18:31:23 CET 2008
20 - minor cleanups.
21 - use much larger stacks on linux and perl < 5.8.8.
22 - Coro::Debug::new_unix_server did not unlink the socket
23 when destroyed.
24
254.911 Tue Nov 11 04:26:17 CET 2008
26 - "port" to threaded perls.
27
284.91 Mon Nov 10 05:36:38 CET 2008
29 - the ->throw exception object no longer leaks.
30 - creating a new cctx leaked a scopestack entry (memleak).
31 - new coroutines didn't get created with a zero flags field
32 (unknown impact).
33 - calling ->throw on a not-yet-started coroutine should now work
34 instead of being ignored.
35 - ->throw is now supported on Coro::State objects.
36 - clean up cctx creation code a bit.
37 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
38
394.9 Sat Nov 8 17:45:27 CET 2008
40 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
41 - (libcoro) no longer leak threads in the experimental pthread backend,
42 also speed it up considerably.
43 - (libcoro) do not rely on makecontext passing void *'s unscathed.
44 - fix compiletime dependencies on libcoro in the Makefile.
45 - cctx_count wasn't always updated properly.
46 - Coro::State::cctx_stacksize wasn't applied correctly.
47 - new function Coro::State::cctx_max_idle.
48 - the default max number of idle C contexts is now 4.
49 - (libcoro) try harder to get _setjmp/_longjmp.
50 - (libcoro) cleanup and extend the libcoro API to officially
51 allow the creation of empty source contexts.
52 - very experimental workaround for the totally broken netbsd platform.
53 - tried to hack around openbsd bugs.
54
554.804 Wed Nov 5 16:36:00 CET 2008
56 - Coro::Debug::new_unix_server would not create a non-blocking listening
57 socket, sometimes causing freezes.
58 - (libcoro) fix misaligned stack points for setjmp and assembly
59 methods, which can cause crashes on x86/x86_64 with a sufficiently
60 aggressive compiler.
61 - new function: Coro::Debug::new_tcp_server.
62 - move ->throw into the Coro class because it only works on coro objects.
63
644.803 Mon Nov 3 17:16:12 CET 2008
65 - (libcoro) use a global asm statement to become independent of gcc
66 otpimisations for CORO_ASM (thanks to pippijn for the idea).
67 - try to workaround yet another broken bsd, this time dragonfly.
68
694.802 Thu Oct 30 10:56:12 CET 2008
70 - support -fno-omit-frame-pointer on x86 with the assembly method.
71 - tune 01_unblock.t tests a bit.
72
734.801 Wed Oct 22 18:33:37 CEST 2008
74 - improve readline speed for very long "lines".
75 - backport to 5.8.8.
76
774.8 Thu Oct 2 13:34:40 CEST 2008
78 - new function Coro::AIO::aio_wait.
79 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
80 - greatly speed up and reduce memory usage of Coro::AIO requests.
81 - implement some other µ-optimisations.
82
834.749 Mon Sep 29 14:40:12 CEST 2008
84 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
85
864.748 Sat Sep 27 14:03:19 CEST 2008
87 - implement, but do not document, PerlIO::cede(granularity).
88 - Coro::Storable forgot to wrap Storable::pstore.
89 - work around the multitude of leaks and memory corruption
90 bugs in PerlIO::via by using our own C-level perliol. As a side
91 effect, Coro::Storable is now much, much, much faster.
92
934.747 Tue Sep 23 01:59:41 CEST 2008
94 - fix a per-cv memleak (one empty array was leaked per
95 code reference).
96 - avoid a crash in coro->call|rss when the coroutine was already
97 destroyed (most noticably when using Coro::Debug::ps :)
98 - also protect *Storable::FILE.
99 - push up default storable granularity to 20ms.
100
1014.746 Sun Sep 21 03:22:20 CEST 2008
102 - be more insistent on locking Storable against reentrancy
103 in Coro::Storable.
104 - move swap_def?v and throw to Coro::State, as documented.
105
1064.745 Thu Jul 24 00:14:38 CEST 2008
107 - remove debugging code related to MgPV_nolen_const, also try to
108 make it compile with perl 5.8.6 (yes, apple apparently loves
109 outdated software). Reported by John S.
110
1114.744 Tue Jul 8 22:06:35 CEST 2008
112 - correctly provide default DIE/WARN handlers as documented.
113 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
114 implementations inside perl work fine for us.
115
1164.743 Mon Jun 16 00:21:57 CEST 2008
117 - when using Coro::EV without running EV::loop it could
118 result in busy-waiting for events, this has been fixed.
119 - reduce codesize and improve performance by using EV_DEFAULT_UC.
120
1214.742 Sat May 31 14:10:21 CEST 2008
122 - implement a workaround for (some) perl <5.8.8 versions.
123 - require EV 3.3+.
124
1254.741 Fri May 30 23:33:09 CEST 2008
126 - tell netbsd how utterly broken their imitation of an OS is
127 and refuse to build by default if pthreads are in use.
128 - switch to "s" method on all bsd's by default, as their ucontext
129 stuff seems just too broken.
130 - fix a bug in Coro::Select.
131
1324.74 Thu May 29 20:05:31 CEST 2008
133 - do not test Coro::LWP for lack of dependencies.
134 - do not test Coro::Select for lack of working perls.
135
1364.73 Thu May 29 2008
137 - fix a bug in Coro::EV which would cause it to block despite
138 there being runnable coroutines.
139 - sprinkle "no warnings" freely over everything, also suppress
140 warnings for some other modules.
141 - fix typo in WSAEWOULDBLOCK.
142
1434.72 Sun May 25 05:14:36 CEST 2008
144 - tweak META.yaml a bit, unfortunately, there is no documented way
145 to have optional dependencies with CPAN. doh :(
146 - avoid running some tests on windows because they would fail due to
147 perl bug (broken fork, broken pipes...).
148 - work around perl on windows bugs where perl returns undocumented
149 error codes for sysread, syswrite etc. by taking advantage
150 of AnyEvent's workaround for that problem.
151 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
152 a common perl implementation bug on windows.
153 - use unix domain sockets in testsuite to work around
154 common perl implementation bugs on widows (they are emulated by
155 tcp sockets on windows. ugh.)
156
1574.71 Sat May 24 20:01:27 CEST 2008
158 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
159 - take advantage of async name resolution of AnyEvent::Util.
160 - work around brutal inet_aton override in Coro::LWP.
161 - take advantage of the readyhook in Coro::EV, for smoother
162 scheduling.
163
1644.7 Sun May 11 00:32:19 CEST 2008
165 - completely reworked the Coro manpage.
166 - added Coro::AnyEvent, generic event loop integration.
167 - implement cancel, ready and kill commands in Coro::Debug.
168 - document find_coro in Coro::Debug.
169 - incompatible change: rename has_stack to has_cctx.
170 - Coro::AIO and Coro::BDB no longer force event model detection,
171 use AnyEvent::AIO and AnyEvent::BDB.
172
1734.6 Sat Apr 26 10:05:14 CEST 2008
174 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
175 by the Coro module. It was a mistake to have it in the first place.
176 - (experimental) support for activestate perl 5.10 (method "w").
177 - (experimental) support for strawberry perl (method "a").
178 - coro_sigelem_set did not return a value although it had to,
179 actual impact unknown.
180
1814.51 Mon Apr 14 13:28:27 CEST 2008
182 - make it compile again on 5.8.
183
1844.50 Thu Apr 10 09:43:17 CEST 2008
185 - I did it twice! (see 4.49).
186
1874.49 Sun Apr 6 21:23:31 CEST 2008
188 - grr, instead of compiling the recent changes on 5.10 only they
189 were compiled on 5.8 only.
190
1914.48 Sun Apr 6 20:36:46 CEST 2008
192 - allow coroutine switches during eval's under 5.10.x, as it seems
193 the parser is a per-interpreter option now, so this is safe
194 (this might fix the odd crashing bug).
195 - drop support for 5.9.x versions: they are dead, jim.
196
1974.47 Sun Apr 6 00:37:52 CEST 2008
198 - force cctx allocation on API calls: we know we need to force one
199 and gcc actually manages to confuse our heuristic nowadays,
200 leading to crashes and worse.
201 - document force_cctx.
202
2034.46 Fri Apr 4 22:05:43 CEST 2008
204 - upgrade libcoro, resulting in pthread-backend (which was only created
205 to fulfill the rules of the programming languages shootout).
206
2074.45 Thu Mar 13 11:55:36 CET 2008
208 - fix a file leaking bug in eg/mhyttpd that would allow
209 downloading of any file (reported by oesi).
210 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
211 (also add testcase).
212 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
213 apparently having loads of fun with that).
214 - implement $state->swap_defsv, ->swap_defav and document ->throw.
215
2164.4 Wed Feb 13 16:44:29 CET 2008
217 - only assume .cfi pseudo isns exist on GNU/Linux.
218 - add get_timed method to Coro::Channels.
219 - fixed Coro::Debug manpage.
220 - perl 5.11 compatbility improvement based on patch by
221 Andreas König.
222
2234.37 Sun Jan 20 11:25:23 CET 2008
224 - soften the check for an active parser for perl 5.10 (avoiding
225 "Coro::State::transfer called while parsing" in many cases).
226
2274.36 Sun Jan 13 10:53:56 CET 2008
228 - reset diehook when terminating from an async_pool as to not
229 trigger any __DIE__ handlers.
230
2314.35 Sun Jan 13 04:14:13 CET 2008
232 - "bt" debug command now displays any exceptions
233 from longmess and also skips the innermost
234 stackframes, giving more useufl output.
235 - allow backtraces in coroutines blocked in Coro::EV,
236 at a <1% speed hit.
237 - handle localising of $SIG{__WARN__} and __DIE__
238 properly (with a proper amount of dirty hacking).
239
2404.34 Sat Dec 22 17:49:53 CET 2007
241 - upgrade to EV version 2.0 API.
242
2434.33 Mon Dec 17 08:36:12 CET 2007
244 - make Coro::AIO etc. loadable in the absence of EV.
245
2464.32 Mon Dec 17 07:46:02 CET 2007
247 - majorly improved Coro::Handle's performance with Coro::EV.
248 - implemented the until now mythical Coro::BDB module.
249 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
250
2514.31 Wed Dec 5 12:32:39 CET 2007
252 - remove warn statement form Coro::Util.
253
2544.3 Tue Dec 4 20:33:14 CET 2007
255 - calls to the idle function could cause stack corruption
256 when the stack changed.
257 - do no longer rely on the presence of EV::DNS if EV is used
258 (because it is gone), but instead take avdantage of EV::ADNS
259 if available.
260 - add ($) prototypes to all functions in Coro::Storable.
261 - use a conventional (safer) idle callback in Coro::EV.
262 - do accept quickly in Coro::Debug to avoid endless loops.
263
2644.22 Fri Nov 30 16:04:04 CET 2007
265 - really use optimised versions for Event and EV in Coro::Util
266 and Coro::Handle.
267
2684.21 Sun Nov 25 10:48:59 CET 2007
269 - fix a spurious memory read.
270 - Coro::EV no longer keeps the eventloop "alive".
271
2724.2 Fri Nov 9 20:47:05 CET 2007
273 - enable/disable tracing from a new coroutine, not a pooled one.
274 - fix a memleak in Coro::Event.
275 - removed killall call from fork_eval.
276 - made sure store_fd is already loaded so that fork_eval
277 does not have to parse autoload in each subprocess.
278 - only use assembly method if -O switch is in $Config{optimize}.
279 - add (optional) Coro::EV module, so far the best event loop module
280 directly supported by Coro.
281 - if the event model is EV, use EV::DNS to resolve
282 stuff in Coro::Util.
283 - don't get confused by multiple event notifications in Coro::Handle.
284 - initial support for EV (libevent interface).
285 - require Event and EV using configure_requires, to force their existance.
286
2874.13 Wed Oct 24 07:26:45 CEST 2007
288 - add Coro::Storable::blocking_thaw.
289 - use a vastly more complicated technique to localise
290 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
291 - use a coroutine for the idle callback Coro::Event,
292 instead of running Event in the current coroutine context.
293 This also catches recursive invocations.
294 - actually report fork errors in gethostbyname and inet_aton.
295
2964.11 Thu Oct 11 02:40:24 CEST 2007
297 - port to threaded perls.
298
2994.1 Thu Oct 11 02:38:16 CEST 2007
300 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
301 be local to each coro (see Coro::State).
302 - incompatible change: for very deep reasons, cede and cede_notself
303 cannot return anything, so nothing will be returned.
304 - possibly bring back 5.10 compatibility (untested).
305 - work around stupid (and wrong) warning on 5.10 :(.
306 - overlay the saved state over the context stack. This saves
307 a few hundred bytes per coroutine on average and also
308 speeds up context switching a bit.
309 - further tune default stack sizes.
310 - (more) correctly calculate stack usage in coro_rss.
311 - Coro::Storable::blocking_* did not properly lock
312 resulting in races between coroutines.
313 - added Coro::Storable::guard.
314 - stopping to trace a coroutine could destroy the cctx of
315 an unrelated coroutine.
316 - explain the relationship between Perl and C coroutines in
317 more detail in Coro::State.
318 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
319 causing a fork per resolve. This also affected Coro::Socket.
320 - switch to a separate stack in $coro->call/eval to avoid
321 invalidating pointers.
322
3234.03 Sat Oct 6 21:24:00 CEST 2007
324 - added Coro::throw method.
325 - minor code cleanups.
326
3274.02 Sat Oct 6 02:36:47 CEST 2007
328 - fix a very minor per-coroutine memleak (a single codereference).
329 - fixed a bug where the currently in-use c context would be freed
330 prematurely (can happen only when programs change the stacksize
331 or use tracing).
332 - tracing can no longer keep a coro alive after it terminated.
333 - do static branch prediction in the common path for gcc. gives
334 about 2-5% speed improvement here.
335
3364.01 Fri Oct 5 22:10:49 CEST 2007
337 - instead of recreating *a* standard output handle we simply
338 use STDOUT, which is faster and hopefully more robust.
339
3404.0 Fri Oct 5 12:56:00 CEST 2007
341 - incompatibly changed Coro::Storable::freeze.
342 - major new feature: added Coro::Debug, for interactive coroutine
343 debugging, tracing and much more.
344 - major bug fix: unbelievable, but true: $_, $/ and many other
345 "saved" variables actually weren't being saved. This has been fixed,
346 of course, while increasing performance while losing all the save
347 flags.
348 - save flags are gone, and all the api functions dealing with them.
349 - added Coro::Semaphore::adjust.
350 - added Coro::Util::fork_eval.
351 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
352 - added Coro::killall.
353 - reduce initial stack sizes to allow for "micro-coroutines".
354 - better async_pool resource management, moved parts of async_pool
355 handling to XS (major speed improvement).
356 - actually croak before modifying important data structures.
357 - refuse to transfer while compiling.
358 - possibly support eval EXPR better now.
359 - enable assembly per default on linux+bsd x86+amd64.
360 - all internal members were renamed _something for easier subclassing.
361 - many minor tweaks.
362
3633.63 Wed May 16 14:10:06 CEST 2007
364 - implement handcoded assembly for x86/amd64 SVR ABI.
365
3663.62 Fri Apr 27 21:36:06 CEST 2007
367 - upgrade libcoro (which might set unwind info correctly).
368 - change default on linux to setjmp/longjmp.
369
3703.61 Thu Apr 19 12:36:18 CEST 2007
371 - Coro::Storable caused an endless loop when thawing invalid
372 pst's sometimes.
373 - use a Semaphore in Coro::Storable, as Storable doesn't
374 seem to be reentrant (although it is documented to
375 be threadsafe...).
376 - fix Coro::Signal to bring back the original unreliable
377 but stateful semantics.
378 - fixed a lot of typos in Coro.pm (patch submitted by David
379 Steinbrunner, which applied flawlessly).
380
3813.6 Sat Apr 14 17:13:31 CEST 2007
382 - added some bugfixes to get eg/myhttpd working again.
383 - added Coro::Storable for often-cede'ing freeze/thaw.
384 - try to do a clean exit when a coroutine calls exit
385 (EXPERIMENTAL).
386 - got rid of indirect call through _coro_init.
387 - updated the partly antique examples in eg/ to
388 work again and be a bit less magic, too.
389 - fixed Coro::Signal semantics to work as documented again.
390
3913.55 Sun Mar 25 01:20:47 CET 2007
392 - add SAVE_DEFFH to save the default filehandle and enable
393 it by default.
394 - finally move socket-operations from Coro::Socket to Coro::Handle
395 to be able to unblock foreign sockets.
396 - add Coro::State::save_also and guarded_save.
397 - add count accessor to Coro::Semaphore.
398 - add Coro::State::cctx_stacksize.
399 - just for the fun of it, do not rely on implicit context,
400 which can dramatically improve performance, but people
401 using windows-process-emulation perls do not care much about
402 performance.
403
4043.51 Sun Mar 4 14:18:04 CET 2007
405 - fixed a problem when you weakened references to Coro::State's
406 (patch by Yuval Kogman).
407
4083.501 Wed Feb 28 12:44:07 CET 2007
409 - rename some global symbols as macosx from hell redefines
410 them without asking.
411
4123.5 Tue Feb 13 20:22:53 CET 2007
413 - do AnyEvent model detection earlier, avoiding problems
414 caused by first using AnyEvent and later Coro::Event.
415 - implement and document Coro::Event event objects.
416 - fix a potential problem in Coro::Event causing crashes.
417 - initialise PL_comppad when creating a new coroutine,
418 avoids crashes on early coro destruction.
419
4203.41 Mon Jan 22 19:19:49 CET 2007
421 - readline on Coro::Handle did not support undefined $/,
422 nor did it deliver partial lines on EOF or error.
423 - implement malloc fallback for stack allocation because
424 stupid broken idiotic OSX has a stupid broken
425 idiotic fits-the-whole-os mmap "implementation" and
426 my dick feels longer if Coro is portable even to
427 obsolete platforms.
428
4293.4 Fri Jan 19 21:52:54 CET 2007
430 - remove t/09_timer.t, as it isn't really testing much
431 but was rather flaky in practise.
432 - async_pool coro would keep arguments and callback alive until
433 it was reused.
434 - cancellation of a coroutine could cause spurious idle calls
435 in cede_notself.
436
4373.3 Sat Jan 6 03:45:00 CET 2007
438 - implement $coro->on_destroy.
439 - Coro::Event blocking semantics have been changed,
440 documented and - hopefully - improved.
441 - fix nice adding, not subtracting, from priority.
442 - fix ->prio and api_is_ready (patch by Mark Hinds).
443 - fixed an assert ("... == prev__cctx->idle_te")
444 that could errronously trigger.
445 - fix various large and small memleaks.
446 - use a (hopefully) more stable cancel implementation
447 that immediately frees the coroutine data.
448 - cede/cede_notself return a status now.
449 - added Coro::guard function.
450 - added a global coroutine pool for jobs (on my machine,
451 I can create and execute 48k simple coros/s with async,
452 and 128k coros with async_pool).
453 - Coro::AIO now uses the coroutine priority as io priority.
454
4553.2 Fri Dec 22 05:07:09 CET 2006
456 - improve portability to slightly older perls.
457 - use cleaner coroutine destruction.
458 - simplify configuration for users.
459 - optionally (unrecommended) prefer perl functions over
460 their coro replacements.
461
4623.11 Tue Dec 5 13:11:24 CET 2006
463 - fixed some bogus assert's, but as perl.h disables assert even
464 without NDEBUG (thank you very much), not too many people should
465 notice (that did include myself). Andreas König noticed, though :)
466 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
467 it. Also noticed by Andreas König :)
468 - save/restore tainted status.
469 - verified to pass the testsuite on my 5.9.5.
470
4713.1 Mon Dec 4 23:03:40 CET 2006
472 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
473 - incompatible change: transfer flags are now per-state.
474 - give a better error message on deadlock.
475 - document Coro::nready.
476 - enhanced testsuite.
477
4783.01 Sun Dec 3 23:47:42 CET 2006
479 - forgot to include Coro::Timer.
480
4813.0 Sun Dec 3 22:57:25 CET 2006
482 - the "FINALLY COMPLETELY STABLE" release (coming soon:
483 the "FAMOUS LAST WORDS" release).
484 - implement a new stack sharing algorithm, which uses a stack
485 pool (size currently hardcoded).
486 - make stack sharing mandatory (it no longer uses a heuristic).
487 - eval/die no longer cause weird problems under heavy use.
488 - Coro::Event could cause livelocks if it was used but
489 no Coro::Event watchers were used.
490 - Coro::Event now uses asynccheck as prepare does not
491 check for changed watchers.
492 - Coro::Event allows multiple waiting coros and will wake up one
493 per event.
494 - Coro::Event should be cleaner and more efficient now.
495 - new utility function Coro::unblock_sub.
496 - document the sad fact that Event is no longer reentrant.
497 - putting a coroutine into the ready queue twice could under
498 some circumstances lead to stack corruption.
499 - minor incompatibility: subclassing Coro::State is supported
500 directly now without going through a _coro_state member.
501 - state/coro switching is much faster now.
502 - very minor optimisations and code/documentation cleanup.
503 - avoid problems due to compiler inlining.
504 - removed timers from Coro::Timer -> use AnyEvent instead.
505 - replaced Coro::idle coroutine by (cleaner) idle handler.
506 - updated to newest libcoro.
507 - implement enhanced support for valgrind.
508 - implement is_ready and return value for ready.
509 - removed Coro::Cont, it was a misnomer (it's generators),
510 and it was somewhat annoying to get it right. Will come back
511 if somebody asks for it :)
512 - many ->wait methods and Coro::Event could return
513 spuriously without the event having happened.
514
5152.5 Tue Nov 7 12:22:33 CET 2006
516 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
517 use AnyEvent, moved them to Coro/.
518 - added Coro::LWP which contains all the uglyness required to
519 make LWP non-blocking.
520 - should work with perl 5.9.x now (Andreas König made me do it).
521 - fixed another bug in Coro::Select when the timeout was undef.
522 - reuse PL_start_env for all coros, saves some memory per coroutine.
523 - manage PL_top_env differently, hopefully to avoid panic: top_env.
524 - timeout argument was not properly used in Coro::Socket.
525 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
526 - emulate undocumented(!) functionality of IO::Socket required
527 by LWP(!!).
528 - updated eg/lwp to work with newer lwp's.
529 - remove "FATAL: uncaught exception" prefix. Coroutines that die
530 kill the whole process, just as exceptions in the main "coroutine"
531 did already.
532
5332.1 Wed Nov 1 23:01:13 CET 2006
534 - fix a long-standing bug in Coro::Select where select with
535 zero timeout would instead change the current default filehandle.
536 - use a simpler and hopefully more robust way to clone padlists
537 (uses less memory and a perl function instead of our own).
538 - coro can now create a stack guard area on many architectures.
539 - Coro::AIO properly reexports additional functions from IO::AIO.
540 - updated libcoro with a workaround for OS X,
541 pach and testing by Michael Schwern.
542
5432.0 Tue Oct 24 05:47:17 CEST 2006
544 - support additional aio requests in Coro::AIO.
545
5461.9 (never properly released due to a glitch)
547
5481.8 Thu Feb 2 00:59:06 CET 2006
549 - applied suggested patch by SAMV to avoid problems during stupid
550 mark & sweep gc run.
551 - applied patch by Scott Walters for 5.9.3 compatibility.
552
5531.7 Tue Dec 27 01:41:58 CET 2005
554 - added Coro::AIO, a thin wrapper around IO::AIO.
555 - improved Makefile.PL explanations.
556
5571.6 Mon Dec 12 21:30:05 CET 2005
558 - additionally save PM_curpm might fix as-of-yet
559 unseen problems with regex matches being attributed to the
560 wrong package.
561 - add t/10_bugs.t, which currently checks against imho broken
562 perls that use 0.26MB of stack space per Perl_magic_get
563 invocation (newer linuxes) as opposed to the 0.0002MB perl
564 normally uses.
565 - make stacksize configurable for the ultimate debian experience.
566
5671.51 Mon Dec 12 18:48:36 CET 2005
568 - remove debugging warn() accidentally left in Coro::Select.
569
5701.5 Tue Nov 29 13:32:44 CET 2005
571 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
572 - fix Coro::Select 'select'.
573 - strict'ify some modules.
574 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
575 - use XSLoader in selected modules.
576 - remove some 5.6 compatibility cruft.
577
5781.4 Tue Sep 6 00:11:05 CEST 2005
579 - libcoro did not take into account the trampoline on amd64,
580 when 'l'inux method was used.
581
5821.31 Tue Aug 30 23:31:33 CEST 2005
583 - some portability fixes/workarounds.
584
5851.3 Sat Aug 20 03:08:56 CEST 2005
586 - no code changes. module seems to work fine.
587 - improve Coro::State docs, remove reference to nonexisting
588 Coro::State::flush method.
589 - no longer autodetect windows, present it as an option instead.
590
5911.2 Mon May 16 02:00:55 CEST 2005
592 - included libcoro.c earlier in State.xs, might improve portability.
593 - use a faster and possibly more stable Coro::Cont implementation.
594 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
595 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
596 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
597
5981.11 Thu Mar 3 18:00:52 CET 2005
599 - change of contact address.
600
6011.1 Tue Feb 22 20:51:16 CET 2005
602 - support [l]inux method on amd64.
603 - allow some context switches while compiling/eval'ing.
604
6051.0 Tue Aug 10 03:47:27 CEST 2004
606 - Event 0.89 fixes the bug again.
607 - fix the remaining(??) memleak. I didn't free the cache-AV for
608 padlists, so one AV per created anon-sub leaked.
609
6100.97 Fri May 14 15:23:32 CEST 2004
611 - remove stupid gcc extension that was an experiment only anyway.
612
6130.96 Thu May 13 18:09:29 CEST 2004
614 - tell people if they have yet another broken Event variant.
615 - made Coro to work _better_ with threads (it seems that, as long
616 as you use Coros in one thread only everything will work fine.
617 Looking at the perl source the problem might be missing locking
618 between Coro and some perl internal routines. That's not easily
619 fixable).
620 - (hopefully) got rid of the static xnext inside transfer.
621
6220.95 Sun Feb 15 03:20:28 CET 2004
623 - removed Coro::State::flush, implemented a new and much
624 faster caching mechanism by attaching magic to the CV.
625 - a memleak with (real) closures remains.
626 - dramatically reduced size of stacks to 65536 (linux/x86), after
627 observing that even myhttpd never had more than a kilobyte
628 of stack in use (stack is still only physically allocated in
629 pagesize increments for systems suporting mmap).
630 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
631 - fix for threaded perl.
632
6330.9 Sun Nov 23 04:32:39 CET 2003
634 - fix a few very hard to track down but (of course) stupid
635 memory leaks.
636 - stringify version number to avoid locale problems :(.
637 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
638 hopefully ignoring it "just works".
639
6400.8 Wed Nov 5 19:38:40 CET 2003
641 - port to perl5.005_03, but only 5.8.x+ is supported!
642 - honor LocalAddr even without LocalPort in Coro::Socket.
643
6440.7 Tue May 27 03:12:38 CEST 2003
645 - the version jump indicates some level of testing, not gobs
646 of new features.
647 - uh... I found the prompt function in ExtUtils::MakeMaker.
648 Highly correct stuff, that is...
649 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
650 the fix is not well understood by the author, so beware :(.
651
6520.652 Thu May 8 02:54:46 CEST 2003
653 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
654 cause version 4 doesn't have ucontext.
655 - Benjamin Reed reported that setjmp works fine on darwin,
656 so preselect it.
657
6580.651 Sat Mar 29 15:00:23 CET 2003
659 - fix a bug in Coro::Handle where some bytes could get lost
660 on reading, reported by jason@nichego.net.
661
6620.65 Sun Mar 23 00:08:26 CET 2003
663 - added a README.linux-glibc.
664 - new module Coro::Select.
665 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
666 (I never claimed that I know what I am doing ;).
667 - set default to setjmp/longjmp on non-x86-linux.
668
6690.6 Thu Nov 21 11:09:06 CET 2002
670 - made lazy context switching the default.
671 - fixed the bug where SemaphoreSet::guard
672 was the same as timed_guard and timed_guard was missing.
673 - fix a memleak in Coro::Timer.
674 - reclassified context sharing as not experimental.
675
6760.534 Sun Apr 14 03:05:12 CEST 2002
677 - fixed backspace => tab in header parsing (myhttpd).
678 - added eg/readline, for elmex.
679 - Coro::Event now calls ->start on first call instead of
680 ->again, which created wrong timeouts for the first ->next.
681 - fixed a bug where Coro::Socket returned a closed socket instead
682 of nothing on ECONNREFUSED and similar error conditions.
683
6840.533 Mon Feb 18 18:49:40 CET 2002
685 - adapt to finally working Event-0.85.
686 - fixed buggy event initialization (trapped under windows, but how
687 could it possibly have worked anywhere?)
688
6890.532 Wed Jan 16 02:45:32 CET 2002
690 - removed the reference to pp_entersub, might work on
691 (some) win32 perls now (testsuite works under cygwin,
692 without Event, which freezes).
693
6940.531 Mon Dec 10 22:18:44 CET 2001
695 - Fixed a bug in SemaphoreSet::timed_down.
696
6970.53 Tue Nov 27 21:11:13 CET 2001
698 - some tests for Event.
699 - slightly different internal architecture to get refcnt into the object
700 and not the reference. might fix a few bugs, certainly did introduce
701 new ones.
702 - Coro::Timer (independent of Event).
703 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
704
7050.52 Tue Nov 6 21:36:18 CET 2001
706 - ported to cygwin (trivial).
707 patch by Gerrit P. Haase <gp@familiehaase.de>.
708 - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
709
7100.51 Thu Nov 1 20:39:01 CET 2001
711 - terminate/cancel now work properly (otherwise termination
712 could cause a "next coroutine is not and contains not..."
713 error.
714 - added Coro::Socket::shutdown.
715 - Coro::Event::loop no is the same as Event::loop.
716 - implemented terminate with args + join.
717
7180.5 Fri Sep 28 16:15:35 CEST 2001
719 - fixed "print" on a Coro::Handle. The print method worked.
720 - small tweaks (seem to reduce memory consumption a lot)
721 in various modules.
722 - splendid use of "no warnings" scattered throughout.
723 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
724
7250.49 Sun Sep 16 02:42:45 CEST 2001
726 - changed some method calls to function calls for speed
727 inside Coro::Handle.
728 - make Coro::Handle use an array instead of a hash for
729 speed reasons.
730 - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
731 sjlj and ucontext should now work.
732 - IRIX-specific port for libcoro.
733 - swapped order of accept results to match IO::Socket.
734 - changed getsock/peername to sock/peername to match IO::Socket.
735 - fixed a bug that caused segfault when returning to main task
736 under some circumstances.
737 - other bugfixes.
738
7390.45 Sun Sep 2 02:54:01 CEST 2001
4 - new method Coro::Handle::timeout. 740 - new method Coro::Handle::timeout.
5 - corrected speling of set...name to get...name in Coro::Socket. 741 - corrected speling of set...name to get...name in Coro::Socket.
6 - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle. 742 - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
7 - Coro::Handle now supports fileno and FILENO. 743 - Coro::Handle now supports fileno and FILENO.
8 - added eg/myhttpd, a web server. 744 - added eg/myhttpd, a web server.
745 - Coro::Socket now accepts numeric ports as well as "port(number)"
746 syntax.
747 - moved some scheduling primitives into xs code. more to come.
748 - new simple priority system.
749 - implemented Coro::Event using XS, almost four times faster!
750 - small memory corruption problem fixed (boy that was difficult).
9 751
100.13 Wed Aug 8 16:53:07 CEST 2001 7520.13 Wed Aug 8 16:53:07 CEST 2001
11 - new method Coro::Handle::readline. 753 - new method Coro::Handle::readline.
12 - added eg/lwp and Coro::Handle::autoflush, to make LWP work. 754 - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
13 (see eg/lwp on how to make LWP non-blocking). 755 (see eg/lwp on how to make LWP non-blocking).
