30.53 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: channel->maxsize(newsize)?
5TODO: __GCC_HAVE_DWARF2_CFI_ASM
6TODO: swap_sv, maybe add scope_swap_sv, andallow to unswap by repeat?
7TODO: swap_sv not undone in pool
8
9 - use a new algorithm to derive padlists for perl 5.18. The old
10 one could lead to 0-pointer accesses inside perl.
11
126.31 Thu May 9 07:39:48 CEST 2013
13 - Coro::AIO requests would crash if the thread was ready'd
14 while the request was ongoing.
15
166.29 Wed May 8 02:55:18 CEST 2013
17 - when an on_destroy handler destructs the coro currently being
18 destructed a perl scalar could be accessed after being freed,
19 likely causing a crash.
20
216.28 Wed Mar 6 06:58:02 CET 2013
22 - clean remnants of existing __DIE__ and __WARN__ handlers so
23 they lose their magic and will not cause segfaults later
24 (testcase by Andrey Sagulin).
25 - improved Coro::State documentation a bit.
26 - Coro::Debug::command now flushes the output.
27 - add hack detection code for x32 abi, because the braindead slugs
28 who designed that made it look exactly like x86_64 without
29 providing proper compile time symbols to test for it. as a result,
30 this detection cannot work reliably.
31 - valgrind stack registering was broken.
32 - do not rely on Time::HiRes anymore in Coro::Debug.
33
346.23 Fri Dec 7 23:36:37 CET 2012
35 - use experimental fiber implementation on native windows
36 perls.
37 - use sizeof (void *) as multiplication factor for stack sizes,
38 to accomodate the totally braindamaged microsoft 64 bit "os".
39 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
40 activeperl 5.16 crashes when PerlIO_define_layer is called due
41 to some bug in the perl dll, strawberry perl at least passes
42 the testsuite.
43 - implement Coro::Handle->peeraddr/host/port, for slightly
44 improved compatibility with LWP.
45 - implement 5.17 compatibility by almost blindly applying a
46 good-looking patch by Father Chrysostomos.
47 - move stack management functions into libcoro 3.
48 - libcoro version 3 "released".
49 - support magic values as timed_io_once args.
50 - recommend AnyEvent 7+ or EV 4+, also require EV
51 version 4 or newer for Coro::EV.
52
536.10 Tue Oct 9 01:14:27 CEST 2012
54 - updated ecb.h, it had a typo that caused it to not compile on many
55 big endian systems (reported by many people).
56 - disable memory fences in ecb.h to improve portability.
57
586.09 Sat Oct 6 23:25:02 CEST 2012
59 - Coro::EV I/O watchers were not interruptible by exceptions
60 (Coro::State::throw) (testcase by sten).
61 - ->throw now puts threads into the ready queue, as this seems to
62 be expected by existing code, and code that doesn't cope with spurious
63 wakeups needs fixing anyway.
64 - use fd -1 in mmap.
65 - cast I32 to int in error message printf.
66 - warn about broken so-called "hardened" kernels.
67
686.08 Fri Apr 13 12:05:47 CEST 2012
69 - be more aggressive about exiting like perl does - formerly,
70 exiting from the non-main thread would not execute END blocks.
71
726.07 Fri Nov 11 21:21:48 CET 2011
73 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
74 - update ecb.h.
75
766.06 Mon Aug 8 23:59:48 CEST 2011
77 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
78 backend, which is an order of magnitude slower. unfortunately, cygwins
79 pthread implementation isn't very complete either, so allocate the stack
80 twice just to be sure.
81 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
82 in its ithreaded perl - best recompile cygwin and use the 'w'indows
83 backend for much better performance. also disable ithreads for
84 even better performance...).
85
866.05 Thu Aug 4 21:36:36 CEST 2011
87 - blush, condvar values would not be propagated from send to recv anymore
88 (reported by Chip Salzenberg).
89 - use exponential increase for the readline buffer length in
90 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
91
926.04 Wed Aug 3 17:15:45 CEST 2011
93 - use even more efficient and more compatible condvars for
94 compatibility to AnyEvent 6.x :)
95 - more inconsequential ecb.h updates.
96
976.03 Wed Aug 3 11:41:30 CEST 2011
98 - change how Coro patches AnyEvent condvars for compatibility to
99 AnyEvent 6.x.
100 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
101 hasn't been included.
102
1036.02 Wed Jul 13 04:35:19 CEST 2011
104 - "improve portability to Gentoo" - gentoo manages to put perl variables
105 in memory areas that are farther than 2gb apart, which the jit couldn't
106 handle and barfed. now it's just a bit slower on gentoo and similar
107 systems.
108
1096.01 Sun Jul 3 12:31:14 CEST 2011
110 - workarounds are good, but the test for whether pthreads are used
111 was not good. thisone should be better.
112 - check differently whether gcc generates cfi instructions itself.
113
1146.0 Wed Jun 29 19:43:35 CEST 2011
115 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
116 destroyed and cleaned up automatically (e.g. async { schedule }).
117 - implement a JIT compiler for part of the thread switch code,
118 which gives a 50% speed improvement on threaded perls, and
119 about 4% on non-thraeded perls (so threaded perls now finally
120 reach about half the speed of non-threaded perls).
121 - slightly modernise Coro::Intro, add section about rouse functions.
122 - avoid DEFSV and ERRSV, giving another 10% improvement
123 in thread switching.
124 - Coro::State->is_destroyed is now called is_zombie.
125 - implement a Coro->safe_cancel method that might fail, but
126 cancels in a "safer" way if it succeeds.
127 - add preliminary support for DEBUGGING perls.
128 - get rid of two hash-accesses when initialising a new Coro - this
129 speeds up coro creation by almost a factor of two.
130 - croak when a coro that is being cancelled tries to block
131 (e.g. while executing a guard block), instead of crashing or
132 deadlocking.
133 - use a more robust and also faster method to identify Coro::State
134 objects - speeds up everything a bit.
135 - implement Coro->cancel in XS for a 20% speed improvement, and to
136 be able to implement mutual cancellation.
137 - speed up context switches by a percent or two by more efficiently
138 allocating context stack entries.
139 - implement Coro->join and Coro->on_destroy in XS for a speedup and
140 a reduction in memory use.
141 - cancelling a coro while it itself is cancelling another coro is
142 now supported and working, instead of triggering an assertion.
143 - be a bit more crash-resistant when calling (buggy) on_destroy
144 callbacks (best effort).
145 - move on_destroy into the slf_frame, to allow extension slf
146 functions to have destructors.
147 - get rid if coro refcounting - simply crash in other interpreter
148 threads by nulling the pointers on clone.
149 - simplify warn/die hook handling when loading Coro - the convoluted
150 logic seems to be no longer neccessary.
151 - use libecb instead of our own home-grown gcc hacks.
152 - document alternatives to Coro::LWP. Please use them :)
153 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
154 sigaltstack. Really. wine suffers from it, erlang suffers from it,
155 and it's known since at least 2006.
156
1575.372 Wed Feb 23 06:14:30 CET 2011
158 - apparently mingw doesn't provide a working gettimeofday, try to
159 work around that by relying on Time::HiRes (indirectly brought to
160 my attention by Max Maischein).
161 - fix some portability issues when Time::HiRes was used.
162
1635.371 Mon Feb 21 14:36:08 CET 2011
164 - backport to windows process emulation code again.
165
1665.37 Sat Feb 19 07:49:44 CET 2011
167 - add a big "Coro thread life cycle" section to "man Coro".
168 - try a tentative workaround against the breakage that 5.13 has
169 introduced without depreciation period. sigh.
170 - no longer use Time::HiRes if gettimeofday is available, which
171 saves quite a lot of memory.
172
1735.36 Sun Feb 13 05:33:41 CET 2011
174 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
175 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
176 method call.
177 - undocument Coro::Timer::sleep and obsolete whole module.
178 - optimise Coro::Timer::timeout memory and cpu usage.
179 - slightly updated Coro::Intro for recent changes.
180 - do not initialise PL_dirty anymore.
181
1825.25 Thu Nov 11 01:08:39 CET 2010
183 - try a different approach on netbsd - netbsd 5 finally has marginally
184 working pthreads, but still broken ucontext/sigaltstack.
185 - openbsd 4.8 finally got their act together, Coro works out of the box
186 with asm, setjmp and pthreads (no change, just informational).
187
1885.24 Sat Oct 23 11:27:12 CEST 2010
189 - port to the EV 4.0 API.
190 - work around bugs in mingw32, making strawberry perl work
191 out of the box.
192 - correctly modify Coro::AIO function prototypes
193 so that they reflect the "no optional parameters" rule.
194 - "ported" libcoro to C++.
195
1965.23 Mon May 17 18:50:42 CEST 2010
197 - be more resistant to ordering changes when initialising
198 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
199 Waldorf).
200 - document that perl 5.12 deliberately removed support for cloning.
201
2025.22 Wed Apr 14 03:55:35 CEST 2010
203 - correctly return udnef on errors in Coro::Handle::read/write
204 (testcase by Marc Mims).
205 - convert Coro::Util into a "perl compatibility wrapper" - the functions
206 are less useful now, but are drop-in replacements for existing
207 functions, listing better alternatives in the documentation. This also
208 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
209 with Coro::Util::inet_aton.
210 - do not override $Coro::idle unconditionally in Coro.pm, as other
211 modules could have provided their own idle coro already
212 (for exmaple, Coro::AnyEvent).
213 - fix Coro::Util::gethost* functions.
214 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
215
2165.21 Wed Dec 16 07:19:51 CET 2009
217 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
218 together.
219 - add some examples on how to combine other event loops with Coro in
220 Coro::AnyEvent, and how to run it (and not to block). Seems to be
221 the most common source of confusion.
222 - try to catch people naively blocking in an event callback.
223 - work around the perl filehandle bug issue in conjunction with
224 older common::sense (as indirectly pointed out by ZSystem).
225 - clarify the "not from signal handlers" section.
226
2275.2 Sun Oct 4 14:54:24 CEST 2009
228 - Coro::Storable destroyed the prototypes of the functions it wrapped.
229 - export rouse_cb and rouse_wait by default now.
230 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
231 - new method $state->swap_sv.
232 - added section on "windows process emulation" to the manpage,
233 after a not-so-fruitful (nor-friendly) "discussion" with chip
234 salzenberg (discussion implies arguments, but his only arguments
235 were ad-hominems, one wonders why he started it in the first
236 place). I hope this explains it well enough for him to understand,
237 and maybe well enough for others to understand.
238 - use common::sense everywhere now.
239 - idle callbacks are no longer supported, use idle coros instead.
240 - print a thread listing when a deadlock is detected.
241
2425.17 Sat Aug 22 23:09:31 CEST 2009
243 - work around a bug in the perl debugger causing crashes
244 when running under the debugger by marking _pool_handler as nodebug.
245 - speed up Coro::async considerably.
246 - try some hacks to get netbsd to work "more often" - their broken
247 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
248 - convert Coro to AE 5.0 API.
249
2505.162 Tue Jul 28 04:04:03 CEST 2009
251 - perl 5.8.2 is now minimum requirement.
252 - skip t/19_handle.t on broken windows perls.
253
2545.161 Wed Jul 22 04:47:38 CEST 2009
255 - Coro::AnyEvent::poll could have a different prototype when EV was
256 used as backend (analyzed by Tatsuhiko Miyagawa).
257 - Coro::AnyEvent errornously initialised the event loop when loaded,
258 not on demand.
259 - try to workaround rare */t/01_unblock.t failures.
260
2615.16 Tue Jul 21 01:44:37 CEST 2009
262 - Coro::AnyEvent failed to hook into the event loop
263 when no threads had been readied between detecting
264 the event loop and actually running it.
265 - considerably speed up Coro::Select by taking avdantage
266 of AnyEvent > 4.8 and some other optimisations.
267 - implement paragraph readline mode in Coro::Handle
268 (based on patches by Zsbán Ambrus).
269 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
270 and analyzed by Yasuhiro MATSUMOTO).
271 - clarified libcoro license and copyright.
272 - someone stole my EXTRA_META!!!
273 - implement Coro::Select::patch_pp_sselect and it's brother,
274 for hardcode select overriding.
275
2765.151 Mon Jul 6 05:41:57 CEST 2009
277 - backport to windows process emulation code again (patch by
278 Yasuhiro MATSUMOTO).
279 - slightly update Coro::MakeMaker.
280
2815.15 Tue Jun 30 10:28:06 CEST 2009
282 - deprecate Coro::Socket, document how to get ipv6 support via
283 AnyEvent::Socket instead.
284 - implement signal->wait ($cb) interface, similar to semaphores.
285 - work around SvOK not supporting getmagic, so we have to getmagic
286 to test for undef :/ (reported by Matthias Waldorf).
287 - load Coro::AnyEvent in all modules using AnyEvent.
288 - work around perl corrupting our internal data structures,
289 reported by Tokuhiro Matsuno.
290 - enable per-coroutine real and cpu time gathering
291 (Coro::State::enable_times).
292
2935.14 Wed Jun 24 01:37:48 CEST 2009
294 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
295 as this seems to have been a difficult concept (poll, sleep, idle,
296 idle_upto).
297 - add Coro::AnyEvent::readable/writable functions.
298 - clarify Coro::EV/Event/AnyEvent manpages.
299 - free per-thread global scalars in the thread calling ->cancel, to
300 avoid crashes when $_, $@ etc., are magical but some of those
301 had already been freed.
302 - "unexperimentalise" the callback interface for Coro::Semaphore.
303 - speed up ready queue management/context switching by using a linked
304 list instead of an array (~5-10%).
305 - implement "watch" command in Coro::Debug shells.
306 - for fun, implement time-slicing as an example in the manpage.
307 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
308 Coro::Event, use the normal AnyEvent handling instead of dieing
309 (the same is true for Coro::Handle).
310 - properly document Coro::EV::timed_io_once.
311 - avoid unneccessary ->cancel calls in Coro::Handle.
312 - maybe make it work on mingw32 with win32 backend
313 (based on patch by Yasuhiro Matsumoto).
314
3155.132 Fri May 29 09:00:39 CEST 2009
316 - do not keep a reference to the argument itself in
317 Coro::Semaphore::guard, as it could change later.
318 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
319 should support a prepare callback.
320
3215.131 Mon Mar 16 23:20:37 CET 2009
322 - implement and document Coro->suspend, Coro->resume.
323 - fix Coro::Select implementation to not (often) close
324 the passed file descriptors (testcase provided by pippijn).
325
3265.13 Mon Dec 15 21:51:42 CET 2008
327 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
328 - don't set diehook to C<undef> but instead to NULL, to avoid
329 spurious warnings.
330 - fix a lot of bugs in Coro::SemaphoreSet.
331 - Coro::SemaphoreSet will less often create a semaphore needlessly.
332 - add Coro::SemaphoreSet::count and wait methods.
333 - take advantage of the new Guard module.
334 - deprecate Coro::guard.
335 - try to fix the dreaded 01_unblock tests once more. I hate it when
336 testsuites need more fixing than the code they are supposed to test.
337 - croak in more cases when a required callback isn't resolvable.
338 - fix some minor issues in Coro::State->call/eval.
339 - use current coroutine context instead of a temporary one
340 when temporarily switching to another coroutine.
341 - do not call C-level on_destroy handlers during global destruction,
342 to avoid needless segfaults.
343
3445.12 Sun Dec 7 13:30:38 CET 2008
345 - add default config for MirOS, which seems to be a bug-to-bug
346 compatible fork of openbsd ("world domination by releasing
347 openbsd cvs before the openbsd folks do it" or so :).
348 - free_padlist did destroy the names pad, not good, but didn't
349 seem to bother perl - this could fix issues such as eval ""
350 inside a function called from multiple coroutines.
351 - use a different method to detect destruction time.
352 - be more careful when freeing padlists just before global
353 destruction.
354 - fixed and expanded the call/cc example.
355 - renamed _terminate to _coro_run.
356 - new method Coro::Channel->shutdown.
357 - try pthreads on openbsd <4.4 (broken sigaltstack, will
358 pthreads fare better?).
359 - be less picky about destroying "a" running coroutine.
360
3615.11 Tue Nov 25 21:49:05 CET 2008
362 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
363 working code with failed assertions, introducing more bugs than
364 it fixes, requiring elaborate workarounds :(
365
3665.1 Mon Nov 24 08:54:59 CET 2008
367 - wrote a small introductory tutorial - Coro::Intro.
368 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
369 - Coro::Select did errornously dup the file descriptors
370 and didn't work with all AnyEvent backends.
371 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
372 LWP data transfers.
373 - disassociate c contexts from coro objects - this is agruably more
374 correct, but mostly allows sharing of cctxs between coro and state
375 objects, for added memory savings and speed increases.
376 - bumped $Coro::POOL_RSS up to 32kb by default.
377 - no longer set the optype to OP_CUSTOM, as B::* understandably
378 doesn't like this very much (and we *are* a type of entersub).
379 - implement state cloning, just to prove that call/cc can be done.
380 - automatically load Coro::AnyEvent in Coro::Handle.
381 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
382 do not have this method (and don't need it either).
383 - speed up generic anyevent methods in Coro::Handle by using rouse
384 callbacks.
385 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
386 others. It also makes the debugger happier, as you can trace
387 through the idle threads now.
388 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
389 - eg/event was pretty broken.
390 - better 5.8.6 compatibility.
391
3925.0 Thu Nov 20 10:35:05 CET 2008
393 - NEW ARCHITECTURE: use the latest 4.x version if you experience
394 stability issues.
395 - bump API version to 7 - all dependents must be recompiled.
396 - removed timed_* functions - they were not being used anyways
397 and should be replaced by a more generic mechanism -
398 and were annoying to support anyways :)
399 - removed SemaphoreSet's waiter method - use sem method instead.
400 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
401 - async_pool did free a scalar value twice
402 ("Attempt to unreference...").
403 - fix a longstanding bug where calling terminate on a coro that
404 was waiting for a semaphore that was just becoming available
405 would cause a deadlock (semaphore would get into a state where
406 it was available but waiters were still blocked).
407 - calling throw on a coroutine that is waiting for a semaphore will
408 no longer make it acquire the semaphore (and thus leak a count).
409 - perl's process emulation is now not even theoretically supported
410 anymore.
411 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
412 conversion of callback-style to blocking-style.
413 - new methods $coro->schedule_to and ->cede_to, to specifically
414 schedule or cede to a specific coroutine.
415 - new function Coro::Semaphore::wait.
416 - use named constants in Coro::Channel (Richard Hundt).
417 - directly patch the entersub opcode calling SLF functions (cede,
418 transfer and so on). this does speed up context switching, but
419 more importanly, it frees us from the hardcoded behaviour of
420 entersub, so we might actually be able to return something from
421 those functions and atcually create new ones.
422 - take advantage of __builtin_frame_address on gcc.
423 - expose THX in coroapi (not sure whether this was a wise decision,
424 as "threaded" perls are running at half speed anyways).
425 - implement execute_slf (schedule-like-function) interface that makes
426 it possible to implement schedule-like-functions in XS.
427 - use new SLF interface to massively speed up Coro::EV by roughly a
428 factor of two.
429 - used new SLF interface to massively speed up Coro::Semaphore by a
430 factor of three.
431 - used new SLF interface to speed up Coro::AIO by roughly a factor of
432 four and reduce its memory usage considerably.
433 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
434 for a nice speedup and vastly more correct behaviour. Also implement
435 a new method "sem" to get at the underlying semaphore object.
436 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
437 (in comparison) 20-40% speedup.
438 - used new SLF interface to reimplement Coro::Signal gaining
439 some unknown (because I was too lazy), but certain, speedup, and also
440 making signals reliable for the first time.
441 - used new SLF interface and other optimisations to speed up async_pool
442 by a factor of two. It also doesn't rely on perl's exception mechanism
443 to exit anymore. The overhead for terminating an async_pool, coro over
444 a normal async is now very small.
445 - sped up coroutine creation/destruction by 40%.
446 - forgot to include Coro/libcoro/README in the dist for all these years.
447 - work around a freebsd pthreads bug (manual testcancel is required as
448 pthread_cond_wait isn't a cancellation point on freebsd).
449 - use new rouse functions to speed up and simplify Coro::BDB.
450 - make "prefer perl native functions" work with threaded perls.
451 - condense Coro::Debug ps output, hint at v and w flags.
452 - (libcoro) lots of minor cleanups and portability improvements.
453
4544.914 Wed Nov 19 12:54:18 CET 2008
455 - fix a disastrous bug in the readline optimisation
456 introduced in 4.801.
457
4584.913 Sat Nov 15 07:58:28 CET 2008
459 - async_pool did free a scalar value twice
460 ("Attempt to unreference...").
461
4624.912 Thu Nov 13 18:31:23 CET 2008
463 - minor cleanups.
464 - use much larger stacks on linux and perl < 5.8.8.
465 - Coro::Debug::new_unix_server did not unlink the socket
466 when destroyed.
467
4684.911 Tue Nov 11 04:26:17 CET 2008
469 - "port" to threaded perls.
470
4714.91 Mon Nov 10 05:36:38 CET 2008
472 - the ->throw exception object no longer leaks.
473 - creating a new cctx leaked a scopestack entry (memleak).
474 - new coroutines didn't get created with a zero flags field
475 (unknown impact).
476 - calling ->throw on a not-yet-started coroutine should now work
477 instead of being ignored.
478 - ->throw is now supported on Coro::State objects.
479 - clean up cctx creation code a bit.
480 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
481
4824.9 Sat Nov 8 17:45:27 CET 2008
483 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
484 - (libcoro) no longer leak threads in the experimental pthread backend,
485 also speed it up considerably.
486 - (libcoro) do not rely on makecontext passing void *'s unscathed.
487 - fix compiletime dependencies on libcoro in the Makefile.
488 - cctx_count wasn't always updated properly.
489 - Coro::State::cctx_stacksize wasn't applied correctly.

494 allow the creation of empty source contexts.
495 - very experimental workaround for the totally broken netbsd platform.
496 - tried to hack around openbsd bugs.
497
4984.804 Wed Nov 5 16:36:00 CET 2008
499 - Coro::Debug::new_unix_server would not create a non-blocking listening
500 socket, sometimes causing freezes.
501 - (libcoro) fix misaligned stack points for setjmp and assembly
502 methods, which can cause crashes on x86/x86_64 with a sufficiently
503 aggressive compiler.
504 - new function: Coro::Debug::new_tcp_server.
505 - move ->throw into the Coro class because it only works on coro objects.
506
5074.803 Mon Nov 3 17:16:12 CET 2008
508 - (libcoro) use a global asm statement to become independent of gcc
509 otpimisations for CORO_ASM (thanks to pippijn for the idea).
510 - try to workaround yet another broken bsd, this time dragonfly.
511
5124.802 Thu Oct 30 10:56:12 CET 2008
513 - support -fno-omit-frame-pointer on x86 with the assembly method.
514 - tune 01_unblock.t tests a bit.
515
5164.801 Wed Oct 22 18:33:37 CEST 2008
517 - improve readline speed for very long "lines".
518 - backport to 5.8.8.
519
5204.8 Thu Oct 2 13:34:40 CEST 2008
521 - new function Coro::AIO::aio_wait.
522 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
523 - greatly speed up and reduce memory usage of Coro::AIO requests.
524 - implement some other µ-optimisations.
525
5264.749 Mon Sep 29 14:40:12 CEST 2008
527 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
528
5294.748 Sat Sep 27 14:03:19 CEST 2008
530 - implement, but do not document, PerlIO::cede(granularity).
531 - Coro::Storable forgot to wrap Storable::pstore.
532 - work around the multitude of leaks and memory corruption
533 bugs in PerlIO::via by using our own C-level perliol. As a side
534 effect, Coro::Storable is now much, much, much faster.
535
5364.747 Tue Sep 23 01:59:41 CEST 2008
537 - fix a per-cv memleak (one empty array was leaked per
538 code reference).
539 - avoid a crash in coro->call|rss when the coroutine was already
540 destroyed (most noticably when using Coro::Debug::ps :)
541 - also protect *Storable::FILE.
542 - push up default storable granularity to 20ms.
543
5444.746 Sun Sep 21 03:22:20 CEST 2008
545 - be more insistent on locking Storable against reentrancy
546 in Coro::Storable.
547 - move swap_def?v and throw to Coro::State, as documented.
548
5494.745 Thu Jul 24 00:14:38 CEST 2008
550 - remove debugging code related to MgPV_nolen_const, also try to
551 make it compile with perl 5.8.6 (yes, apple apparently loves
552 outdated software). Reported by John S.
553
5544.744 Tue Jul 8 22:06:35 CEST 2008
555 - correctly provide default DIE/WARN handlers as documented.
556 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
557 implementations inside perl work fine for us.
558
5594.743 Mon Jun 16 00:21:57 CEST 2008
560 - when using Coro::EV without running EV::loop it could
561 result in busy-waiting for events, this has been fixed.
562 - reduce codesize and improve performance by using EV_DEFAULT_UC.
563
5644.742 Sat May 31 14:10:21 CEST 2008
565 - implement a workaround for (some) perl <5.8.8 versions.
566 - require EV 3.3+.
567
5684.741 Fri May 30 23:33:09 CEST 2008
569 - tell netbsd how utterly broken their imitation of an OS is
570 and refuse to build by default if pthreads are in use.
571 - switch to "s" method on all bsd's by default, as their ucontext
572 stuff seems just too broken.
573 - fix a bug in Coro::Select.
574
5754.74 Thu May 29 20:05:31 CEST 2008
576 - do not test Coro::LWP for lack of dependencies.
577 - do not test Coro::Select for lack of working perls.
578
5794.73 Thu May 29 2008
580 - fix a bug in Coro::EV which would cause it to block despite
581 there being runnable coroutines.
582 - sprinkle "no warnings" freely over everything, also suppress
583 warnings for some other modules.
584 - fix typo in WSAEWOULDBLOCK.
585
5864.72 Sun May 25 05:14:36 CEST 2008
587 - tweak META.yaml a bit, unfortunately, there is no documented way
588 to have optional dependencies with CPAN. doh :(
589 - avoid running some tests on windows because they would fail due to
590 perl bug (broken fork, broken pipes...).
591 - work around perl on windows bugs where perl returns undocumented
592 error codes for sysread, syswrite etc. by taking advantage
593 of AnyEvent's workaround for that problem.
594 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
595 a common perl implementation bug on windows.
596 - use unix domain sockets in testsuite to work around
597 common perl implementation bugs on widows (they are emulated by
598 tcp sockets on windows. ugh.)
599
6004.71 Sat May 24 20:01:27 CEST 2008
601 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
602 - take advantage of async name resolution of AnyEvent::Util.
603 - work around brutal inet_aton override in Coro::LWP.
604 - take advantage of the readyhook in Coro::EV, for smoother
605 scheduling.
606
6074.7 Sun May 11 00:32:19 CEST 2008
608 - completely reworked the Coro manpage.
609 - added Coro::AnyEvent, generic event loop integration.
610 - implement cancel, ready and kill commands in Coro::Debug.
611 - document find_coro in Coro::Debug.
612 - incompatible change: rename has_stack to has_cctx.
613 - Coro::AIO and Coro::BDB no longer force event model detection,
614 use AnyEvent::AIO and AnyEvent::BDB.
615
6164.6 Sat Apr 26 10:05:14 CEST 2008
617 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
618 by the Coro module. It was a mistake to have it in the first place.
619 - (experimental) support for activestate perl 5.10 (method "w").
620 - (experimental) support for strawberry perl (method "a").
621 - coro_sigelem_set did not return a value although it had to,
622 actual impact unknown.
623
6244.51 Mon Apr 14 13:28:27 CEST 2008
625 - make it compile again on 5.8.
626
6274.50 Thu Apr 10 09:43:17 CEST 2008
628 - I did it twice! (see 4.49).
629
6304.49 Sun Apr 6 21:23:31 CEST 2008
631 - grr, instead of compiling the recent changes on 5.10 only they
632 were compiled on 5.8 only.
633
6344.48 Sun Apr 6 20:36:46 CEST 2008
635 - allow coroutine switches during eval's under 5.10.x, as it seems
636 the parser is a per-interpreter option now, so this is safe
637 (this might fix the odd crashing bug).
638 - drop support for 5.9.x versions: they are dead, jim.
639
6404.47 Sun Apr 6 00:37:52 CEST 2008
641 - force cctx allocation on API calls: we know we need to force one
642 and gcc actually manages to confuse our heuristic nowadays,
643 leading to crashes and worse.
644 - document force_cctx.
645
6464.46 Fri Apr 4 22:05:43 CEST 2008
647 - upgrade libcoro, resulting in pthread-backend (which was only created
648 to fulfill the rules of the programming languages shootout).
649
6504.45 Thu Mar 13 11:55:36 CET 2008
651 - fix a file leaking bug in eg/mhyttpd that would allow
652 downloading of any file (reported by oesi).
653 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
654 (also add testcase).
655 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
656 apparently having loads of fun with that).
657 - implement $state->swap_defsv, ->swap_defav and document ->throw.
658
6594.4 Wed Feb 13 16:44:29 CET 2008
660 - only assume .cfi pseudo isns exist on GNU/Linux.
661 - add get_timed method to Coro::Channels.
662 - fixed Coro::Debug manpage.
663 - perl 5.11 compatbility improvement based on patch by
664 Andreas König.
665
6664.37 Sun Jan 20 11:25:23 CET 2008
667 - soften the check for an active parser for perl 5.10 (avoiding
668 "Coro::State::transfer called while parsing" in many cases).
669
6704.36 Sun Jan 13 10:53:56 CET 2008
671 - reset diehook when terminating from an async_pool as to not
672 trigger any __DIE__ handlers.
673
6744.35 Sun Jan 13 04:14:13 CET 2008
675 - "bt" debug command now displays any exceptions
676 from longmess and also skips the innermost
677 stackframes, giving more useufl output.
678 - allow backtraces in coroutines blocked in Coro::EV,
679 at a <1% speed hit.
680 - handle localising of $SIG{__WARN__} and __DIE__
681 properly (with a proper amount of dirty hacking).
682
6834.34 Sat Dec 22 17:49:53 CET 2007
684 - upgrade to EV version 2.0 API.
685
6864.33 Mon Dec 17 08:36:12 CET 2007
687 - make Coro::AIO etc. loadable in the absence of EV.
688
6894.32 Mon Dec 17 07:46:02 CET 2007
690 - majorly improved Coro::Handle's performance with Coro::EV.
691 - implemented the until now mythical Coro::BDB module.
692 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
693
6944.31 Wed Dec 5 12:32:39 CET 2007
695 - remove warn statement form Coro::Util.
696
6974.3 Tue Dec 4 20:33:14 CET 2007
698 - calls to the idle function could cause stack corruption
699 when the stack changed.
700 - do no longer rely on the presence of EV::DNS if EV is used
701 (because it is gone), but instead take avdantage of EV::ADNS
702 if available.
703 - add ($) prototypes to all functions in Coro::Storable.
704 - use a conventional (safer) idle callback in Coro::EV.
705 - do accept quickly in Coro::Debug to avoid endless loops.
706
7074.22 Fri Nov 30 16:04:04 CET 2007
708 - really use optimised versions for Event and EV in Coro::Util
709 and Coro::Handle.
710
7114.21 Sun Nov 25 10:48:59 CET 2007
712 - fix a spurious memory read.
713 - Coro::EV no longer keeps the eventloop "alive".
714
7154.2 Fri Nov 9 20:47:05 CET 2007
716 - enable/disable tracing from a new coroutine, not a pooled one.
717 - fix a memleak in Coro::Event.
718 - removed killall call from fork_eval.
719 - made sure store_fd is already loaded so that fork_eval
720 does not have to parse autoload in each subprocess.
721 - only use assembly method if -O switch is in $Config{optimize}.
722 - add (optional) Coro::EV module, so far the best event loop module
723 directly supported by Coro.
724 - if the event model is EV, use EV::DNS to resolve
725 stuff in Coro::Util.
726 - don't get confused by multiple event notifications in Coro::Handle.
727 - initial support for EV (libevent interface).
728 - require Event and EV using configure_requires, to force their existance.
729
7304.13 Wed Oct 24 07:26:45 CEST 2007
731 - add Coro::Storable::blocking_thaw.
732 - use a vastly more complicated technique to localise
733 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
734 - use a coroutine for the idle callback Coro::Event,
735 instead of running Event in the current coroutine context.
736 This also catches recursive invocations.
737 - actually report fork errors in gethostbyname and inet_aton.
738
7394.11 Thu Oct 11 02:40:24 CEST 2007
740 - port to threaded perls.
741
7424.1 Thu Oct 11 02:38:16 CEST 2007
743 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
744 be local to each coro (see Coro::State).
745 - incompatible change: for very deep reasons, cede and cede_notself
746 cannot return anything, so nothing will be returned.
747 - possibly bring back 5.10 compatibility (untested).
748 - work around stupid (and wrong) warning on 5.10 :(.
749 - overlay the saved state over the context stack. This saves
750 a few hundred bytes per coroutine on average and also
751 speeds up context switching a bit.
752 - further tune default stack sizes.
753 - (more) correctly calculate stack usage in coro_rss.
754 - Coro::Storable::blocking_* did not properly lock
755 resulting in races between coroutines.
756 - added Coro::Storable::guard.
757 - stopping to trace a coroutine could destroy the cctx of
758 an unrelated coroutine.
759 - explain the relationship between Perl and C coroutines in
760 more detail in Coro::State.
761 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
762 causing a fork per resolve. This also affected Coro::Socket.
763 - switch to a separate stack in $coro->call/eval to avoid
764 invalidating pointers.
765
7664.03 Sat Oct 6 21:24:00 CEST 2007
767 - added Coro::throw method.
768 - minor code cleanups.
769
7704.02 Sat Oct 6 02:36:47 CEST 2007
771 - fix a very minor per-coroutine memleak (a single codereference).
772 - fixed a bug where the currently in-use c context would be freed
773 prematurely (can happen only when programs change the stacksize
774 or use tracing).
775 - tracing can no longer keep a coro alive after it terminated.
776 - do static branch prediction in the common path for gcc. gives
777 about 2-5% speed improvement here.
778
7794.01 Fri Oct 5 22:10:49 CEST 2007
780 - instead of recreating *a* standard output handle we simply
781 use STDOUT, which is faster and hopefully more robust.
782
7834.0 Fri Oct 5 12:56:00 CEST 2007
784 - incompatibly changed Coro::Storable::freeze.
785 - major new feature: added Coro::Debug, for interactive coroutine
786 debugging, tracing and much more.
787 - major bug fix: unbelievable, but true: $_, $/ and many other
788 "saved" variables actually weren't being saved. This has been fixed,
789 of course, while increasing performance while losing all the save
790 flags.
791 - save flags are gone, and all the api functions dealing with them.
792 - added Coro::Semaphore::adjust.
793 - added Coro::Util::fork_eval.
794 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
795 - added Coro::killall.
796 - reduce initial stack sizes to allow for "micro-coroutines".
797 - better async_pool resource management, moved parts of async_pool
798 handling to XS (major speed improvement).
799 - actually croak before modifying important data structures.
800 - refuse to transfer while compiling.
801 - possibly support eval EXPR better now.
802 - enable assembly per default on linux+bsd x86+amd64.
803 - all internal members were renamed _something for easier subclassing.
804 - many minor tweaks.
805
8063.63 Wed May 16 14:10:06 CEST 2007
807 - implement handcoded assembly for x86/amd64 SVR ABI.
808
8093.62 Fri Apr 27 21:36:06 CEST 2007
810 - upgrade libcoro (which might set unwind info correctly).
811 - change default on linux to setjmp/longjmp.
812
8133.61 Thu Apr 19 12:36:18 CEST 2007
814 - Coro::Storable caused an endless loop when thawing invalid
815 pst's sometimes.
816 - use a Semaphore in Coro::Storable, as Storable doesn't
817 seem to be reentrant (although it is documented to
818 be threadsafe...).
819 - fix Coro::Signal to bring back the original unreliable
820 but stateful semantics.
821 - fixed a lot of typos in Coro.pm (patch submitted by David
822 Steinbrunner, which applied flawlessly).
823
8243.6 Sat Apr 14 17:13:31 CEST 2007
825 - added some bugfixes to get eg/myhttpd working again.
826 - added Coro::Storable for often-cede'ing freeze/thaw.
827 - try to do a clean exit when a coroutine calls exit
828 (EXPERIMENTAL).
829 - got rid of indirect call through _coro_init.
830 - updated the partly antique examples in eg/ to
831 work again and be a bit less magic, too.
832 - fixed Coro::Signal semantics to work as documented again.
833
8343.55 Sun Mar 25 01:20:47 CET 2007
835 - add SAVE_DEFFH to save the default filehandle and enable
836 it by default.
837 - finally move socket-operations from Coro::Socket to Coro::Handle
838 to be able to unblock foreign sockets.
839 - add Coro::State::save_also and guarded_save.
840 - add count accessor to Coro::Semaphore.
841 - add Coro::State::cctx_stacksize.
842 - just for the fun of it, do not rely on implicit context,
843 which can dramatically improve performance, but people
844 using windows-process-emulation perls do not care much about
845 performance.
846
8473.51 Sun Mar 4 14:18:04 CET 2007
848 - fixed a problem when you weakened references to Coro::State's
849 (patch by Yuval Kogman).
850
8513.501 Wed Feb 28 12:44:07 CET 2007
852 - rename some global symbols as macosx from hell redefines
853 them without asking.
854
8553.5 Tue Feb 13 20:22:53 CET 2007
856 - do AnyEvent model detection earlier, avoiding problems
857 caused by first using AnyEvent and later Coro::Event.
858 - implement and document Coro::Event event objects.
859 - fix a potential problem in Coro::Event causing crashes.
860 - initialise PL_comppad when creating a new coroutine,
861 avoids crashes on early coro destruction.
862
8633.41 Mon Jan 22 19:19:49 CET 2007
864 - readline on Coro::Handle did not support undefined $/,
865 nor did it deliver partial lines on EOF or error.
866 - implement malloc fallback for stack allocation because
867 stupid broken idiotic OSX has a stupid broken
868 idiotic fits-the-whole-os mmap "implementation" and
869 my dick feels longer if Coro is portable even to
870 obsolete platforms.
871
8723.4 Fri Jan 19 21:52:54 CET 2007
873 - remove t/09_timer.t, as it isn't really testing much
874 but was rather flaky in practise.
875 - async_pool coro would keep arguments and callback alive until
876 it was reused.
877 - cancellation of a coroutine could cause spurious idle calls
878 in cede_notself.
879
8803.3 Sat Jan 6 03:45:00 CET 2007
881 - implement $coro->on_destroy.
882 - Coro::Event blocking semantics have been changed,
883 documented and - hopefully - improved.
884 - fix nice adding, not subtracting, from priority.
885 - fix ->prio and api_is_ready (patch by Mark Hinds).
886 - fixed an assert ("... == prev__cctx->idle_te")
887 that could errronously trigger.
888 - fix various large and small memleaks.
889 - use a (hopefully) more stable cancel implementation
890 that immediately frees the coroutine data.
891 - cede/cede_notself return a status now.
892 - added Coro::guard function.
893 - added a global coroutine pool for jobs (on my machine,
894 I can create and execute 48k simple coros/s with async,
895 and 128k coros with async_pool).
896 - Coro::AIO now uses the coroutine priority as io priority.
897
8983.2 Fri Dec 22 05:07:09 CET 2006
899 - improve portability to slightly older perls.
900 - use cleaner coroutine destruction.
901 - simplify configuration for users.
902 - optionally (unrecommended) prefer perl functions over
903 their coro replacements.
904
9053.11 Tue Dec 5 13:11:24 CET 2006
906 - fixed some bogus assert's, but as perl.h disables assert even
907 without NDEBUG (thank you very much), not too many people should
908 notice (that did include myself). Andreas König noticed, though :)
909 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
910 it. Also noticed by Andreas König :)
911 - save/restore tainted status.
912 - verified to pass the testsuite on my 5.9.5.
913
9143.1 Mon Dec 4 23:03:40 CET 2006
915 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
916 - incompatible change: transfer flags are now per-state.
917 - give a better error message on deadlock.
918 - document Coro::nready.
919 - enhanced testsuite.
920
9213.01 Sun Dec 3 23:47:42 CET 2006
922 - forgot to include Coro::Timer.
923
9243.0 Sun Dec 3 22:57:25 CET 2006
925 - the "FINALLY COMPLETELY STABLE" release (coming soon:
926 the "FAMOUS LAST WORDS" release).
927 - implement a new stack sharing algorithm, which uses a stack
928 pool (size currently hardcoded).
929 - make stack sharing mandatory (it no longer uses a heuristic).
930 - eval/die no longer cause weird problems under heavy use.
931 - Coro::Event could cause livelocks if it was used but
932 no Coro::Event watchers were used.
933 - Coro::Event now uses asynccheck as prepare does not
934 check for changed watchers.
935 - Coro::Event allows multiple waiting coros and will wake up one
936 per event.
937 - Coro::Event should be cleaner and more efficient now.
938 - new utility function Coro::unblock_sub.
939 - document the sad fact that Event is no longer reentrant.
940 - putting a coroutine into the ready queue twice could under
941 some circumstances lead to stack corruption.
942 - minor incompatibility: subclassing Coro::State is supported
943 directly now without going through a _coro_state member.
944 - state/coro switching is much faster now.
945 - very minor optimisations and code/documentation cleanup.
946 - avoid problems due to compiler inlining.
947 - removed timers from Coro::Timer -> use AnyEvent instead.
948 - replaced Coro::idle coroutine by (cleaner) idle handler.
949 - updated to newest libcoro.
950 - implement enhanced support for valgrind.
951 - implement is_ready and return value for ready.
952 - removed Coro::Cont, it was a misnomer (it's generators),
953 and it was somewhat annoying to get it right. Will come back
954 if somebody asks for it :)
955 - many ->wait methods and Coro::Event could return
956 spuriously without the event having happened.
957
9582.5 Tue Nov 7 12:22:33 CET 2006
959 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
960 use AnyEvent, moved them to Coro/.
961 - added Coro::LWP which contains all the uglyness required to
962 make LWP non-blocking.
963 - should work with perl 5.9.x now (Andreas König made me do it).
964 - fixed another bug in Coro::Select when the timeout was undef.
965 - reuse PL_start_env for all coros, saves some memory per coroutine.
966 - manage PL_top_env differently, hopefully to avoid panic: top_env.
967 - timeout argument was not properly used in Coro::Socket.
968 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
969 - emulate undocumented(!) functionality of IO::Socket required
970 by LWP(!!).
971 - updated eg/lwp to work with newer lwp's.
972 - remove "FATAL: uncaught exception" prefix. Coroutines that die
973 kill the whole process, just as exceptions in the main "coroutine"
974 did already.
975
9762.1 Wed Nov 1 23:01:13 CET 2006
977 - fix a long-standing bug in Coro::Select where select with
978 zero timeout would instead change the current default filehandle.
979 - use a simpler and hopefully more robust way to clone padlists
980 (uses less memory and a perl function instead of our own).
981 - coro can now create a stack guard area on many architectures.
982 - Coro::AIO properly reexports additional functions from IO::AIO.
983 - updated libcoro with a workaround for OS X,
984 pach and testing by Michael Schwern.
985
9862.0 Tue Oct 24 05:47:17 CEST 2006
987 - support additional aio requests in Coro::AIO.
988
9891.9 (never properly released due to a glitch)
990
9911.8 Thu Feb 2 00:59:06 CET 2006
992 - applied suggested patch by SAMV to avoid problems during stupid
993 mark & sweep gc run.
994 - applied patch by Scott Walters for 5.9.3 compatibility.
995
9961.7 Tue Dec 27 01:41:58 CET 2005
997 - added Coro::AIO, a thin wrapper around IO::AIO.
998 - improved Makefile.PL explanations.
999
10001.6 Mon Dec 12 21:30:05 CET 2005
1001 - additionally save PM_curpm might fix as-of-yet
1002 unseen problems with regex matches being attributed to the
1003 wrong package.
1004 - add t/10_bugs.t, which currently checks against imho broken
1005 perls that use 0.26MB of stack space per Perl_magic_get
1006 invocation (newer linuxes) as opposed to the 0.0002MB perl
1007 normally uses.
1008 - make stacksize configurable for the ultimate debian experience.
1009
10101.51 Mon Dec 12 18:48:36 CET 2005
1011 - remove debugging warn() accidentally left in Coro::Select.
1012
10131.5 Tue Nov 29 13:32:44 CET 2005
1014 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
1015 - fix Coro::Select 'select'.
1016 - strict'ify some modules.
1017 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
1018 - use XSLoader in selected modules.
1019 - remove some 5.6 compatibility cruft.
1020
10211.4 Tue Sep 6 00:11:05 CEST 2005
1022 - libcoro did not take into account the trampoline on amd64,
1023 when 'l'inux method was used.
1024
10251.31 Tue Aug 30 23:31:33 CEST 2005
1026 - some portability fixes/workarounds.
1027
10281.3 Sat Aug 20 03:08:56 CEST 2005
1029 - no code changes. module seems to work fine.
1030 - improve Coro::State docs, remove reference to nonexisting
1031 Coro::State::flush method.
1032 - no longer autodetect windows, present it as an option instead.
1033
10341.2 Mon May 16 02:00:55 CEST 2005
1035 - included libcoro.c earlier in State.xs, might improve portability.
1036 - use a faster and possibly more stable Coro::Cont implementation.
1037 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
1038 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
1039 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
1040
10411.11 Thu Mar 3 18:00:52 CET 2005
1042 - change of contact address.
1043
10441.1 Tue Feb 22 20:51:16 CET 2005
1045 - support [l]inux method on amd64.
1046 - allow some context switches while compiling/eval'ing.
1047
10481.0 Tue Aug 10 03:47:27 CEST 2004
1049 - Event 0.89 fixes the bug again.
1050 - fix the remaining(??) memleak. I didn't free the cache-AV for
1051 padlists, so one AV per created anon-sub leaked.
1052
10530.97 Fri May 14 15:23:32 CEST 2004
1054 - remove stupid gcc extension that was an experiment only anyway.
1055
10560.96 Thu May 13 18:09:29 CEST 2004
1057 - tell people if they have yet another broken Event variant.
1058 - made Coro to work _better_ with threads (it seems that, as long
1059 as you use Coros in one thread only everything will work fine.
1060 Looking at the perl source the problem might be missing locking
1061 between Coro and some perl internal routines. That's not easily
1062 fixable).
1063 - (hopefully) got rid of the static xnext inside transfer.
1064
10650.95 Sun Feb 15 03:20:28 CET 2004
1066 - removed Coro::State::flush, implemented a new and much
1067 faster caching mechanism by attaching magic to the CV.
1068 - a memleak with (real) closures remains.
1069 - dramatically reduced size of stacks to 65536 (linux/x86), after
1070 observing that even myhttpd never had more than a kilobyte
1071 of stack in use (stack is still only physically allocated in
1072 pagesize increments for systems suporting mmap).
1073 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
1074 - fix for threaded perl.
1075
10760.9 Sun Nov 23 04:32:39 CET 2003
1077 - fix a few very hard to track down but (of course) stupid
1078 memory leaks.
1079 - stringify version number to avoid locale problems :(.
1080 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
1081 hopefully ignoring it "just works".
1082
10830.8 Wed Nov 5 19:38:40 CET 2003
1084 - port to perl5.005_03, but only 5.8.x+ is supported!
1085 - honor LocalAddr even without LocalPort in Coro::Socket.
1086
10870.7 Tue May 27 03:12:38 CEST 2003
1088 - the version jump indicates some level of testing, not gobs
1089 of new features.
1090 - uh... I found the prompt function in ExtUtils::MakeMaker.
1091 Highly correct stuff, that is...
1092 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
1093 the fix is not well understood by the author, so beware :(.
1094
10950.652 Thu May 8 02:54:46 CEST 2003
1096 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
1097 cause version 4 doesn't have ucontext.
1098 - Benjamin Reed reported that setjmp works fine on darwin,
1099 so preselect it.
1100
11010.651 Sat Mar 29 15:00:23 CET 2003
1102 - fix a bug in Coro::Handle where some bytes could get lost
1103 on reading, reported by jason@nichego.net.
1104
11050.65 Sun Mar 23 00:08:26 CET 2003
1106 - added a README.linux-glibc.
1107 - new module Coro::Select.
1108 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
1109 (I never claimed that I know what I am doing ;).
1110 - set default to setjmp/longjmp on non-x86-linux.
1111
11120.6 Thu Nov 21 11:09:06 CET 2002
1113 - made lazy context switching the default.
1114 - fixed the bug where SemaphoreSet::guard
1115 was the same as timed_guard and timed_guard was missing.
1116 - fix a memleak in Coro::Timer.
1117 - reclassified context sharing as not experimental.
1118
11190.534 Sun Apr 14 03:05:12 CEST 2002
1120 - fixed backspace => tab in header parsing (myhttpd).
1121 - added eg/readline, for elmex.
1122 - Coro::Event now calls ->start on first call instead of
1123 ->again, which created wrong timeouts for the first ->next.
1124 - fixed a bug where Coro::Socket returned a closed socket instead
1125 of nothing on ECONNREFUSED and similar error conditions.
1126
11270.533 Mon Feb 18 18:49:40 CET 2002
1128 - adapt to finally working Event-0.85.
1129 - fixed buggy event initialization (trapped under windows, but how
1130 could it possibly have worked anywhere?)
1131
11320.532 Wed Jan 16 02:45:32 CET 2002
1133 - removed the reference to pp_entersub, might work on
1134 (some) win32 perls now (testsuite works under cygwin,
1135 without Event, which freezes).
1136
11370.531 Mon Dec 10 22:18:44 CET 2001
1138 - Fixed a bug in SemaphoreSet::timed_down.
1139
