3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO. 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: maybe implement a default message channel, very much like Erlang's 4TODO: channel->maxsize(newsize)?
5 actor model (which is cool in a lot of important aspects (failures!), 5TODO: __GCC_HAVE_DWARF2_CFI_ASM
6 but very lacking in others (higher level ipc)). 6TODO: swap_sv, maybe add scope_swap_sv, andallow to unswap by repeat?
7TODO: swap_sv not undone in pool
8TODO: croak when async_pool tries to run canceled thread?

106.48 Sun Oct 4 19:03:51 CEST 2015
11 - fix memory leak when Coro::Handle uses Coro::EV internally
12 (testcase by Sten Sten).
13 - update code to libev 4 API (internally, Coro still used the
14 version 3 API calls).
15 - remove unused hv_sig.
16
176.47 Sat Jul 11 03:58:20 CEST 2015
18 - swap_svs - NVs can be in the SV head beginning with 5.20.
19
206.46 Tue Jun 30 14:36:30 CEST 2015
21 - restore portability to perls with windows fork emulation
22 (patch by Petr Písař).
23
246.45 Tue Jun 30 01:40:08 CEST 2015
25 - restore portability to perl 5.16 and below.
26
276.44 Tue Jun 30 00:41:54 CEST 2015
28 - avoid segfaulting (or worse) when tracing a canceled thread.
29 - the Event module silently broke it's public hook API, causing
30 failures on perls compiled with -Duselongdouble. Requiring
31 the latest version of Event because I don't know which release
32 changed this (it's not mentioned in the ChangeLog).
33 - allow xs level enterleave hooks via CoroAPI.
34
356.43 Thu Jun 4 15:38:14 CEST 2015
36 - use stability canary.
37 - port to stableperl-5.22.0-1.001.
38 - update libecb.
39
406.42 Wed Feb 11 20:29:52 CET 2015
41 - Coro::SemaphoreSet->try did not actually work (analyzed by
42 SATO Kentaro).
43 - upgrade libecb to be C11 compliant.
44
456.41 Sat Sep 6 22:08:46 CEST 2014
46 - restore portability to perl 5.8.x.
47 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
48 up some memory, but fixes "use feature" and similar modules
49 when used inside a Coro.
50 - allow zero as argument to Coro::Channel to mean the same thing
51 as no argument. this works with older versions as well,
52 but wasn't legal until now.
53 - slightly better c header file detection.
54
556.39 Mon Jun 2 00:00:08 CEST 2014
56 - work around more incompatible changes in 5.20.
57
586.38 Sun Jun 1 21:54:23 CEST 2014
59 - check that perl slots actually have enough space to hold
60 interpreter variables.
61 - untested port to perl 5.19 (64 bit tmps indices) (reported
62 by Andreas König).
63 - croak when cancel is called without a thread context.
64
656.37 Tue Mar 4 13:27:33 CET 2014
66 - *sigh*, removed leftover debugging code from debugging a
67 perl bug, of all things.
68
696.36 Tue Mar 4 07:11:59 CET 2014
70 - semaphores would not clear the destroy hook when interrupted
71 by ->throw, causing segfaults or worse.
72 - ->throw on a thread waiting for a semaphore did not acquire
73 the semaphore, but also didn't wake up other waiters,
74 possibly causing a deadlock.
75 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
76 to report a full stacktrace, which should help find out
77 where the actual call is.
78 - "atomically" destroy data in slf_destroy, because it is
79 the right thing to do, just in case.
80 - disable ecb.h libm dependency, to compile on ancient systems
81 or under adverse conditions.
82
836.33 Mon Nov 18 11:26:27 CET 2013
84 - do not crash when freeing padlists with holes (in 5.18).
85 - tentative SVt_BIND 5.19 port/fix.
86
876.32 Tue Nov 5 15:35:35 CET 2013
88 - use a new algorithm to derive padlists for perl 5.18. The old
89 one could lead to 0-pointer accesses inside perl (reported
90 by Darin McBride).
91
926.31 Thu May 9 07:39:48 CEST 2013
93 - Coro::AIO requests would crash if the thread was ready'd
94 while the request was ongoing.
95
966.29 Wed May 8 02:55:18 CEST 2013
97 - when an on_destroy handler destructs the coro currently being
98 destructed a perl scalar could be accessed after being freed,
99 likely causing a crash.
100
1016.28 Wed Mar 6 06:58:02 CET 2013
102 - clean remnants of existing __DIE__ and __WARN__ handlers so
103 they lose their magic and will not cause segfaults later
104 (testcase by Andrey Sagulin).
105 - improved Coro::State documentation a bit.
106 - Coro::Debug::command now flushes the output.
107 - add hack detection code for x32 abi, because the braindead slugs
108 who designed that made it look exactly like x86_64 without
109 providing proper compile time symbols to test for it. as a result,
110 this detection cannot work reliably.
111 - valgrind stack registering was broken.
112 - do not rely on Time::HiRes anymore in Coro::Debug.
113
1146.23 Fri Dec 7 23:36:37 CET 2012
115 - use experimental fiber implementation on native windows
116 perls.
117 - use sizeof (void *) as multiplication factor for stack sizes,
118 to accomodate the totally braindamaged microsoft 64 bit "os".
119 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
120 activeperl 5.16 crashes when PerlIO_define_layer is called due
121 to some bug in the perl dll, strawberry perl at least passes
122 the testsuite.
123 - implement Coro::Handle->peeraddr/host/port, for slightly
124 improved compatibility with LWP.
125 - implement 5.17 compatibility by almost blindly applying a
126 good-looking patch by Father Chrysostomos.
127 - move stack management functions into libcoro 3.
128 - libcoro version 3 "released".
129 - support magic values as timed_io_once args.
130 - recommend AnyEvent 7+ or EV 4+, also require EV
131 version 4 or newer for Coro::EV.
132
1336.10 Tue Oct 9 01:14:27 CEST 2012
134 - updated ecb.h, it had a typo that caused it to not compile on many
135 big endian systems (reported by many people).
136 - disable memory fences in ecb.h to improve portability.
137
1386.09 Sat Oct 6 23:25:02 CEST 2012
139 - Coro::EV I/O watchers were not interruptible by exceptions
140 (Coro::State::throw) (testcase by sten).
141 - ->throw now puts threads into the ready queue, as this seems to
142 be expected by existing code, and code that doesn't cope with spurious
143 wakeups needs fixing anyway.
144 - use fd -1 in mmap.
145 - cast I32 to int in error message printf.
146 - warn about broken so-called "hardened" kernels.
147
1486.08 Fri Apr 13 12:05:47 CEST 2012
149 - be more aggressive about exiting like perl does - formerly,
150 exiting from the non-main thread would not execute END blocks.
151
1526.07 Fri Nov 11 21:21:48 CET 2011
153 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
154 - update ecb.h.
155
1566.06 Mon Aug 8 23:59:48 CEST 2011
157 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
158 backend, which is an order of magnitude slower. unfortunately, cygwins
159 pthread implementation isn't very complete either, so allocate the stack
160 twice just to be sure.
161 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
162 in its ithreaded perl - best recompile cygwin and use the 'w'indows
163 backend for much better performance. also disable ithreads for
164 even better performance...).
165
1666.05 Thu Aug 4 21:36:36 CEST 2011
167 - blush, condvar values would not be propagated from send to recv anymore
168 (reported by Chip Salzenberg).
169 - use exponential increase for the readline buffer length in
170 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
171
1726.04 Wed Aug 3 17:15:45 CEST 2011
173 - use even more efficient and more compatible condvars for
174 compatibility to AnyEvent 6.x :)
175 - more inconsequential ecb.h updates.
176
1776.03 Wed Aug 3 11:41:30 CEST 2011
178 - change how Coro patches AnyEvent condvars for compatibility to
179 AnyEvent 6.x.
180 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
181 hasn't been included.
182
1836.02 Wed Jul 13 04:35:19 CEST 2011
184 - "improve portability to Gentoo" - gentoo manages to put perl variables
185 in memory areas that are farther than 2gb apart, which the jit couldn't
186 handle and barfed. now it's just a bit slower on gentoo and similar
187 systems.
188
1896.01 Sun Jul 3 12:31:14 CEST 2011
190 - workarounds are good, but the test for whether pthreads are used
191 was not good. this one should be better.
192 - check differently whether gcc generates cfi instructions itself.
193
1946.0 Wed Jun 29 19:43:35 CEST 2011
195 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
196 destroyed and cleaned up automatically (e.g. async { schedule }).
197 - implement a JIT compiler for part of the thread switch code,
198 which gives a 50% speed improvement on threaded perls, and
199 about 4% on non-threaded perls (so threaded perls now finally
200 reach about half the speed of non-threaded perls).
201 - slightly modernise Coro::Intro, add section about rouse functions.
202 - avoid DEFSV and ERRSV, giving another 10% improvement
203 in thread switching.
204 - Coro::State->is_destroyed is now called is_zombie.
205 - implement a Coro->safe_cancel method that might fail, but
206 cancels in a "safer" way if it succeeds.
207 - add preliminary support for DEBUGGING perls.
208 - get rid of two hash-accesses when initialising a new Coro - this
209 speeds up coro creation by almost a factor of two.
210 - croak when a coro that is being cancelled tries to block
211 (e.g. while executing a guard block), instead of crashing or
212 deadlocking.
213 - use a more robust and also faster method to identify Coro::State
214 objects - speeds up everything a bit.
215 - implement Coro->cancel in XS for a 20% speed improvement, and to
216 be able to implement mutual cancellation.
217 - speed up context switches by a percent or two by more efficiently
218 allocating context stack entries.
219 - implement Coro->join and Coro->on_destroy in XS for a speedup and
220 a reduction in memory use.
221 - cancelling a coro while it itself is cancelling another coro is
222 now supported and working, instead of triggering an assertion.
223 - be a bit more crash-resistant when calling (buggy) on_destroy
224 callbacks (best effort).
225 - move on_destroy into the slf_frame, to allow extension slf
226 functions to have destructors.
227 - get rid if coro refcounting - simply crash in other interpreter
228 threads by nulling the pointers on clone.
229 - simplify warn/die hook handling when loading Coro - the convoluted
230 logic seems to be no longer neccessary.
231 - use libecb instead of our own home-grown gcc hacks.
232 - document alternatives to Coro::LWP. Please use them :)
233 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
234 sigaltstack. Really. wine suffers from it, erlang suffers from it,
235 and it's known since at least 2006.
236
2375.372 Wed Feb 23 06:14:30 CET 2011
238 - apparently mingw doesn't provide a working gettimeofday, try to
239 work around that by relying on Time::HiRes (indirectly brought to
240 my attention by Max Maischein).
241 - fix some portability issues when Time::HiRes was used.
242
2435.371 Mon Feb 21 14:36:08 CET 2011
244 - backport to windows process emulation code again.
245
2465.37 Sat Feb 19 07:49:44 CET 2011
247 - add a big "Coro thread life cycle" section to "man Coro".
248 - try a tentative workaround against the breakage that 5.13 has
249 introduced without depreciation period. sigh.
250 - no longer use Time::HiRes if gettimeofday is available, which
251 saves quite a lot of memory.
252
2535.36 Sun Feb 13 05:33:41 CET 2011
254 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
255 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
256 method call.
257 - undocument Coro::Timer::sleep and obsolete whole module.
258 - optimise Coro::Timer::timeout memory and cpu usage.
259 - slightly updated Coro::Intro for recent changes.
260 - do not initialise PL_dirty anymore.
261
2625.25 Thu Nov 11 01:08:39 CET 2010
263 - try a different approach on netbsd - netbsd 5 finally has marginally
264 working pthreads, but still broken ucontext/sigaltstack.
265 - openbsd 4.8 finally got their act together, Coro works out of the box
266 with asm, setjmp and pthreads (no change, just informational).
267
2685.24 Sat Oct 23 11:27:12 CEST 2010
269 - port to the EV 4.0 API.
270 - work around bugs in mingw32, making strawberry perl work
271 out of the box.
272 - correctly modify Coro::AIO function prototypes
273 so that they reflect the "no optional parameters" rule.
274 - "ported" libcoro to C++.
275
2765.23 Mon May 17 18:50:42 CEST 2010
277 - be more resistant to ordering changes when initialising
278 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
279 Waldorf).
280 - document that perl 5.12 deliberately removed support for cloning.
281
2825.22 Wed Apr 14 03:55:35 CEST 2010
283 - correctly return udnef on errors in Coro::Handle::read/write
284 (testcase by Marc Mims).
285 - convert Coro::Util into a "perl compatibility wrapper" - the functions
286 are less useful now, but are drop-in replacements for existing
287 functions, listing better alternatives in the documentation. This also
288 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
289 with Coro::Util::inet_aton.
290 - do not override $Coro::idle unconditionally in Coro.pm, as other
291 modules could have provided their own idle coro already
292 (for exmaple, Coro::AnyEvent).
293 - fix Coro::Util::gethost* functions.
294 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
295
2965.21 Wed Dec 16 07:19:51 CET 2009
297 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
298 together.
299 - add some examples on how to combine other event loops with Coro in
300 Coro::AnyEvent, and how to run it (and not to block). Seems to be
301 the most common source of confusion.
302 - try to catch people naively blocking in an event callback.
303 - work around the perl filehandle bug issue in conjunction with
304 older common::sense (as indirectly pointed out by ZSystem).
305 - clarify the "not from signal handlers" section.
306
3075.2 Sun Oct 4 14:54:24 CEST 2009
308 - Coro::Storable destroyed the prototypes of the functions it wrapped.
309 - export rouse_cb and rouse_wait by default now.
310 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
311 - new method $state->swap_sv.
312 - added section on "windows process emulation" to the manpage,
313 after a not-so-fruitful (nor-friendly) "discussion" with chip
314 salzenberg (discussion implies arguments, but his only arguments
315 were ad-hominems, one wonders why he started it in the first
316 place). I hope this explains it well enough for him to understand,
317 and maybe well enough for others to understand.
318 - use common::sense everywhere now.
319 - idle callbacks are no longer supported, use idle coros instead.
320 - print a thread listing when a deadlock is detected.
321
3225.17 Sat Aug 22 23:09:31 CEST 2009
323 - work around a bug in the perl debugger causing crashes
324 when running under the debugger by marking _pool_handler as nodebug.
325 - speed up Coro::async considerably.
326 - try some hacks to get netbsd to work "more often" - their broken
327 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
328 - convert Coro to AE 5.0 API.
329
3305.162 Tue Jul 28 04:04:03 CEST 2009
331 - perl 5.8.2 is now minimum requirement.
332 - skip t/19_handle.t on broken windows perls.
333
3345.161 Wed Jul 22 04:47:38 CEST 2009
335 - Coro::AnyEvent::poll could have a different prototype when EV was
336 used as backend (analyzed by Tatsuhiko Miyagawa).
337 - Coro::AnyEvent errornously initialised the event loop when loaded,
338 not on demand.
339 - try to workaround rare */t/01_unblock.t failures.
340
3415.16 Tue Jul 21 01:44:37 CEST 2009
342 - Coro::AnyEvent failed to hook into the event loop
343 when no threads had been readied between detecting
344 the event loop and actually running it.
345 - considerably speed up Coro::Select by taking avdantage
346 of AnyEvent > 4.8 and some other optimisations.
347 - implement paragraph readline mode in Coro::Handle
348 (based on patches by Zsbán Ambrus).
349 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
350 and analyzed by Yasuhiro MATSUMOTO).
351 - clarified libcoro license and copyright.
352 - someone stole my EXTRA_META!!!
353 - implement Coro::Select::patch_pp_sselect and it's brother,
354 for hardcode select overriding.
355
3565.151 Mon Jul 6 05:41:57 CEST 2009
357 - backport to windows process emulation code again (patch by
358 Yasuhiro MATSUMOTO).
359 - slightly update Coro::MakeMaker.
360
3615.15 Tue Jun 30 10:28:06 CEST 2009
362 - deprecate Coro::Socket, document how to get ipv6 support via
363 AnyEvent::Socket instead.
364 - implement signal->wait ($cb) interface, similar to semaphores.
365 - work around SvOK not supporting getmagic, so we have to getmagic
366 to test for undef :/ (reported by Matthias Waldorf).
367 - load Coro::AnyEvent in all modules using AnyEvent.
368 - work around perl corrupting our internal data structures,
369 reported by Tokuhiro Matsuno.
370 - enable per-coroutine real and cpu time gathering
371 (Coro::State::enable_times).
372
3735.14 Wed Jun 24 01:37:48 CEST 2009
374 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
375 as this seems to have been a difficult concept (poll, sleep, idle,
376 idle_upto).
377 - add Coro::AnyEvent::readable/writable functions.
378 - clarify Coro::EV/Event/AnyEvent manpages.
379 - free per-thread global scalars in the thread calling ->cancel, to
380 avoid crashes when $_, $@ etc., are magical but some of those
381 had already been freed.
382 - "unexperimentalise" the callback interface for Coro::Semaphore.
383 - speed up ready queue management/context switching by using a linked
384 list instead of an array (~5-10%).
385 - implement "watch" command in Coro::Debug shells.
386 - for fun, implement time-slicing as an example in the manpage.
387 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
388 Coro::Event, use the normal AnyEvent handling instead of dieing
389 (the same is true for Coro::Handle).
390 - properly document Coro::EV::timed_io_once.
391 - avoid unneccessary ->cancel calls in Coro::Handle.
392 - maybe make it work on mingw32 with win32 backend
393 (based on patch by Yasuhiro Matsumoto).
394
3955.132 Fri May 29 09:00:39 CEST 2009
396 - do not keep a reference to the argument itself in
397 Coro::Semaphore::guard, as it could change later.
398 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
399 should support a prepare callback.
400
4015.131 Mon Mar 16 23:20:37 CET 2009
402 - implement and document Coro->suspend, Coro->resume.
403 - fix Coro::Select implementation to not (often) close
404 the passed file descriptors (testcase provided by pippijn).
405
4065.13 Mon Dec 15 21:51:42 CET 2008
407 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
408 - don't set diehook to C<undef> but instead to NULL, to avoid
409 spurious warnings.
410 - fix a lot of bugs in Coro::SemaphoreSet.
411 - Coro::SemaphoreSet will less often create a semaphore needlessly.
412 - add Coro::SemaphoreSet::count and wait methods.
413 - take advantage of the new Guard module.
414 - deprecate Coro::guard.
415 - try to fix the dreaded 01_unblock tests once more. I hate it when
416 testsuites need more fixing than the code they are supposed to test.
417 - croak in more cases when a required callback isn't resolvable.
418 - fix some minor issues in Coro::State->call/eval.
419 - use current coroutine context instead of a temporary one
420 when temporarily switching to another coroutine.
421 - do not call C-level on_destroy handlers during global destruction,
422 to avoid needless segfaults.
423
4245.12 Sun Dec 7 13:30:38 CET 2008
425 - add default config for MirOS, which seems to be a bug-to-bug
426 compatible fork of openbsd ("world domination by releasing
427 openbsd cvs before the openbsd folks do it" or so :).
428 - free_padlist did destroy the names pad, not good, but didn't
429 seem to bother perl - this could fix issues such as eval ""
430 inside a function called from multiple coroutines.
431 - use a different method to detect destruction time.
432 - be more careful when freeing padlists just before global
433 destruction.
434 - fixed and expanded the call/cc example.
435 - renamed _terminate to _coro_run.
436 - new method Coro::Channel->shutdown.
437 - try pthreads on openbsd <4.4 (broken sigaltstack, will
438 pthreads fare better?).
439 - be less picky about destroying "a" running coroutine.
440
4415.11 Tue Nov 25 21:49:05 CET 2008
442 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
443 working code with failed assertions, introducing more bugs than
444 it fixes, requiring elaborate workarounds :(
445
4465.1 Mon Nov 24 08:54:59 CET 2008
447 - wrote a small introductory tutorial - Coro::Intro.
448 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
449 - Coro::Select did errornously dup the file descriptors
450 and didn't work with all AnyEvent backends.
451 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
452 LWP data transfers.
453 - disassociate c contexts from coro objects - this is agruably more
454 correct, but mostly allows sharing of cctxs between coro and state
455 objects, for added memory savings and speed increases.
456 - bumped $Coro::POOL_RSS up to 32kb by default.
457 - no longer set the optype to OP_CUSTOM, as B::* understandably
458 doesn't like this very much (and we *are* a type of entersub).
459 - implement state cloning, just to prove that call/cc can be done.
460 - automatically load Coro::AnyEvent in Coro::Handle.
461 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
462 do not have this method (and don't need it either).
463 - speed up generic anyevent methods in Coro::Handle by using rouse
464 callbacks.
465 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
466 others. It also makes the debugger happier, as you can trace
467 through the idle threads now.
468 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
469 - eg/event was pretty broken.
470 - better 5.8.6 compatibility.
471
4725.0 Thu Nov 20 10:35:05 CET 2008
473 - NEW ARCHITECTURE: use the latest 4.x version if you experience
474 stability issues.
475 - bump API version to 7 - all dependents must be recompiled.
476 - removed timed_* functions - they were not being used anyways
477 and should be replaced by a more generic mechanism -
478 and were annoying to support anyways :)
479 - removed SemaphoreSet's waiter method - use sem method instead.
480 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
481 - async_pool did free a scalar value twice
482 ("Attempt to unreference...").
483 - fix a longstanding bug where calling terminate on a coro that
484 was waiting for a semaphore that was just becoming available
485 would cause a deadlock (semaphore would get into a state where
486 it was available but waiters were still blocked).
487 - calling throw on a coroutine that is waiting for a semaphore will
488 no longer make it acquire the semaphore (and thus leak a count).
489 - perl's process emulation is now not even theoretically supported
490 anymore.
491 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
492 conversion of callback-style to blocking-style.
493 - new methods $coro->schedule_to and ->cede_to, to specifically
494 schedule or cede to a specific coroutine.
495 - new function Coro::Semaphore::wait.
496 - use named constants in Coro::Channel (Richard Hundt).
497 - directly patch the entersub opcode calling SLF functions (cede,
498 transfer and so on). this does speed up context switching, but
499 more importanly, it frees us from the hardcoded behaviour of
500 entersub, so we might actually be able to return something from
501 those functions and atcually create new ones.
502 - take advantage of __builtin_frame_address on gcc.
503 - expose THX in coroapi (not sure whether this was a wise decision,
504 as "threaded" perls are running at half speed anyways).
505 - implement execute_slf (schedule-like-function) interface that makes
506 it possible to implement schedule-like-functions in XS.
507 - use new SLF interface to massively speed up Coro::EV by roughly a
508 factor of two.
509 - used new SLF interface to massively speed up Coro::Semaphore by a
510 factor of three.
511 - used new SLF interface to speed up Coro::AIO by roughly a factor of
512 four and reduce its memory usage considerably.
513 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
514 for a nice speedup and vastly more correct behaviour. Also implement
515 a new method "sem" to get at the underlying semaphore object.
516 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
517 (in comparison) 20-40% speedup.
518 - used new SLF interface to reimplement Coro::Signal gaining
519 some unknown (because I was too lazy), but certain, speedup, and also
520 making signals reliable for the first time.
521 - used new SLF interface and other optimisations to speed up async_pool
522 by a factor of two. It also doesn't rely on perl's exception mechanism
523 to exit anymore. The overhead for terminating an async_pool, coro over
524 a normal async is now very small.
525 - sped up coroutine creation/destruction by 40%.
526 - forgot to include Coro/libcoro/README in the dist for all these years.
527 - work around a freebsd pthreads bug (manual testcancel is required as
528 pthread_cond_wait isn't a cancellation point on freebsd).
529 - use new rouse functions to speed up and simplify Coro::BDB.
530 - make "prefer perl native functions" work with threaded perls.
531 - condense Coro::Debug ps output, hint at v and w flags.
532 - (libcoro) lots of minor cleanups and portability improvements.
533
5344.914 Wed Nov 19 12:54:18 CET 2008
535 - fix a disastrous bug in the readline optimisation
536 introduced in 4.801.
537
5384.913 Sat Nov 15 07:58:28 CET 2008
539 - async_pool did free a scalar value twice
540 ("Attempt to unreference...").

5424.912 Thu Nov 13 18:31:23 CET 2008
543 - minor cleanups.
544 - use much larger stacks on linux and perl < 5.8.8.
545 - Coro::Debug::new_unix_server did not unlink the socket
546 when destroyed.
547
5484.911 Tue Nov 11 04:26:17 CET 2008
549 - "port" to threaded perls.
550
5514.91 Mon Nov 10 05:36:38 CET 2008
552 - the ->throw exception object no longer leaks.
553 - creating a new cctx leaked a scopestack entry (memleak).
554 - new coroutines didn't get created with a zero flags field
555 (unknown impact).
556 - calling ->throw on a not-yet-started coroutine should now work
557 instead of being ignored.
558 - ->throw is now supported on Coro::State objects.
559 - clean up cctx creation code a bit.
560 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
561
5624.9 Sat Nov 8 17:45:27 CET 2008
563 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
564 - (libcoro) no longer leak threads in the experimental pthread backend,
565 also speed it up considerably.
566 - (libcoro) do not rely on makecontext passing void *'s unscathed.
567 - fix compiletime dependencies on libcoro in the Makefile.
568 - cctx_count wasn't always updated properly.
569 - Coro::State::cctx_stacksize wasn't applied correctly.
570 - new function Coro::State::cctx_max_idle.
571 - the default max number of idle C contexts is now 4.
572 - (libcoro) try harder to get _setjmp/_longjmp.
573 - (libcoro) cleanup and extend the libcoro API to officially
574 allow the creation of empty source contexts.
575 - very experimental workaround for the totally broken netbsd platform.
576 - tried to hack around openbsd bugs.
577
5784.804 Wed Nov 5 16:36:00 CET 2008
579 - Coro::Debug::new_unix_server would not create a non-blocking listening
580 socket, sometimes causing freezes.
581 - (libcoro) fix misaligned stack points for setjmp and assembly
582 methods, which can cause crashes on x86/x86_64 with a sufficiently
583 aggressive compiler.
584 - new function: Coro::Debug::new_tcp_server.
585 - move ->throw into the Coro class because it only works on coro objects.
586
5874.803 Mon Nov 3 17:16:12 CET 2008
588 - (libcoro) use a global asm statement to become independent of gcc
589 otpimisations for CORO_ASM (thanks to pippijn for the idea).
590 - try to workaround yet another broken bsd, this time dragonfly.
591
5924.802 Thu Oct 30 10:56:12 CET 2008
593 - support -fno-omit-frame-pointer on x86 with the assembly method.

595
5964.801 Wed Oct 22 18:33:37 CEST 2008

603 - greatly speed up and reduce memory usage of Coro::AIO requests.
604 - implement some other µ-optimisations.
605
6064.749 Mon Sep 29 14:40:12 CEST 2008

610 - implement, but do not document, PerlIO::cede(granularity).
611 - Coro::Storable forgot to wrap Storable::pstore.
612 - work around the multitude of leaks and memory corruption
613 bugs in PerlIO::via by using our own C-level perliol. As a side
614 effect, Coro::Storable is now much, much, much faster.
615
6164.747 Tue Sep 23 01:59:41 CEST 2008
617 - fix a per-cv memleak (one empty array was leaked per
618 code reference).

620 destroyed (most noticably when using Coro::Debug::ps :)
621 - also protect *Storable::FILE.
622 - push up default storable granularity to 20ms.
