3TODO: should explore PerlIO::coroaio (perl leaks like hell). 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?

8TODO: croak when async_pool tries to run canceled thread?
7 9
10 - split Coro::Semaphore::up/adjust into separate xs functions
11 for better error reporting, at slight codesize increase.
12
136.49 Sat Oct 17 01:40:12 CEST 2015
14 - throwing an exception to a thread waiting in
15 Coro::Handle using Coro::EV did not stop the watchers,
16 causing the next call to fail (testcase by Martin Pritchard).
17 - bump minimum perl version to 5.10.
18
196.48 Sun Oct 4 19:03:51 CEST 2015
20 - fix memory leak when Coro::Handle uses Coro::EV internally
21 (testcase by Sten Sten).
22 - update code to libev 4 API (internally, Coro still used the
23 version 3 API calls).
24 - remove unused hv_sig.
25
266.47 Sat Jul 11 03:58:20 CEST 2015
27 - swap_svs - NVs can be in the SV head beginning with 5.20.
28
296.46 Tue Jun 30 14:36:30 CEST 2015
30 - restore portability to perls with windows fork emulation
31 (patch by Petr Písař).
32
336.45 Tue Jun 30 01:40:08 CEST 2015
34 - restore portability to perl 5.16 and below.
35
366.44 Tue Jun 30 00:41:54 CEST 2015
37 - avoid segfaulting (or worse) when tracing a canceled thread.
38 - the Event module silently broke it's public hook API, causing
39 failures on perls compiled with -Duselongdouble. Requiring
40 the latest version of Event because I don't know which release
41 changed this (it's not mentioned in the ChangeLog).
42 - allow xs level enterleave hooks via CoroAPI.
43
446.43 Thu Jun 4 15:38:14 CEST 2015
45 - use stability canary.
46 - port to stableperl-5.22.0-1.001.
47 - update libecb.
48
496.42 Wed Feb 11 20:29:52 CET 2015
50 - Coro::SemaphoreSet->try did not actually work (analyzed by
51 SATO Kentaro).
52 - upgrade libecb to be C11 compliant.
53
546.41 Sat Sep 6 22:08:46 CEST 2014
55 - restore portability to perl 5.8.x.
56 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
57 up some memory, but fixes "use feature" and similar modules
58 when used inside a Coro.
59 - allow zero as argument to Coro::Channel to mean the same thing
60 as no argument. this works with older versions as well,
61 but wasn't legal until now.
62 - slightly better c header file detection.
63
646.39 Mon Jun 2 00:00:08 CEST 2014
65 - work around more incompatible changes in 5.20.
66
676.38 Sun Jun 1 21:54:23 CEST 2014
68 - check that perl slots actually have enough space to hold
69 interpreter variables.
70 - untested port to perl 5.19 (64 bit tmps indices) (reported
71 by Andreas König).
72 - croak when cancel is called without a thread context.
73
746.37 Tue Mar 4 13:27:33 CET 2014
75 - *sigh*, removed leftover debugging code from debugging a
76 perl bug, of all things.
77
786.36 Tue Mar 4 07:11:59 CET 2014
79 - semaphores would not clear the destroy hook when interrupted
80 by ->throw, causing segfaults or worse.
81 - ->throw on a thread waiting for a semaphore did not acquire
82 the semaphore, but also didn't wake up other waiters,
83 possibly causing a deadlock.
84 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
85 to report a full stacktrace, which should help find out
86 where the actual call is.
87 - "atomically" destroy data in slf_destroy, because it is
88 the right thing to do, just in case.
89 - disable ecb.h libm dependency, to compile on ancient systems
90 or under adverse conditions.
91
926.33 Mon Nov 18 11:26:27 CET 2013
93 - do not crash when freeing padlists with holes (in 5.18).
94 - tentative SVt_BIND 5.19 port/fix.
95
966.32 Tue Nov 5 15:35:35 CET 2013
97 - use a new algorithm to derive padlists for perl 5.18. The old
98 one could lead to 0-pointer accesses inside perl (reported
99 by Darin McBride).
100
1016.31 Thu May 9 07:39:48 CEST 2013
102 - Coro::AIO requests would crash if the thread was ready'd
103 while the request was ongoing.
104
1056.29 Wed May 8 02:55:18 CEST 2013
106 - when an on_destroy handler destructs the coro currently being
107 destructed a perl scalar could be accessed after being freed,
108 likely causing a crash.
109
1106.28 Wed Mar 6 06:58:02 CET 2013
111 - clean remnants of existing __DIE__ and __WARN__ handlers so
112 they lose their magic and will not cause segfaults later
113 (testcase by Andrey Sagulin).
114 - improved Coro::State documentation a bit.
115 - Coro::Debug::command now flushes the output.
116 - add hack detection code for x32 abi, because the braindead slugs
117 who designed that made it look exactly like x86_64 without
118 providing proper compile time symbols to test for it. as a result,
119 this detection cannot work reliably.
120 - valgrind stack registering was broken.
121 - do not rely on Time::HiRes anymore in Coro::Debug.
122
1236.23 Fri Dec 7 23:36:37 CET 2012
124 - use experimental fiber implementation on native windows
125 perls.
126 - use sizeof (void *) as multiplication factor for stack sizes,
127 to accomodate the totally braindamaged microsoft 64 bit "os".
128 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
129 activeperl 5.16 crashes when PerlIO_define_layer is called due
130 to some bug in the perl dll, strawberry perl at least passes
131 the testsuite.
132 - implement Coro::Handle->peeraddr/host/port, for slightly
133 improved compatibility with LWP.
134 - implement 5.17 compatibility by almost blindly applying a
135 good-looking patch by Father Chrysostomos.
136 - move stack management functions into libcoro 3.
137 - libcoro version 3 "released".
138 - support magic values as timed_io_once args.
139 - recommend AnyEvent 7+ or EV 4+, also require EV
140 version 4 or newer for Coro::EV.
141
1426.10 Tue Oct 9 01:14:27 CEST 2012
143 - updated ecb.h, it had a typo that caused it to not compile on many
144 big endian systems (reported by many people).
145 - disable memory fences in ecb.h to improve portability.
146
1476.09 Sat Oct 6 23:25:02 CEST 2012
148 - Coro::EV I/O watchers were not interruptible by exceptions
149 (Coro::State::throw) (testcase by sten).
150 - ->throw now puts threads into the ready queue, as this seems to
151 be expected by existing code, and code that doesn't cope with spurious
152 wakeups needs fixing anyway.
153 - use fd -1 in mmap.
154 - cast I32 to int in error message printf.
155 - warn about broken so-called "hardened" kernels.
156
1576.08 Fri Apr 13 12:05:47 CEST 2012
158 - be more aggressive about exiting like perl does - formerly,
159 exiting from the non-main thread would not execute END blocks.
160
1616.07 Fri Nov 11 21:21:48 CET 2011
162 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
163 - update ecb.h.
164
1656.06 Mon Aug 8 23:59:48 CEST 2011
166 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
167 backend, which is an order of magnitude slower. unfortunately, cygwins
168 pthread implementation isn't very complete either, so allocate the stack
169 twice just to be sure.
170 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
171 in its ithreaded perl - best recompile cygwin and use the 'w'indows
172 backend for much better performance. also disable ithreads for
173 even better performance...).
174
1756.05 Thu Aug 4 21:36:36 CEST 2011
176 - blush, condvar values would not be propagated from send to recv anymore
177 (reported by Chip Salzenberg).
178 - use exponential increase for the readline buffer length in
179 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
180
1816.04 Wed Aug 3 17:15:45 CEST 2011
182 - use even more efficient and more compatible condvars for
183 compatibility to AnyEvent 6.x :)
184 - more inconsequential ecb.h updates.
185
1866.03 Wed Aug 3 11:41:30 CEST 2011
187 - change how Coro patches AnyEvent condvars for compatibility to
188 AnyEvent 6.x.
189 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
190 hasn't been included.
191
1926.02 Wed Jul 13 04:35:19 CEST 2011
193 - "improve portability to Gentoo" - gentoo manages to put perl variables
194 in memory areas that are farther than 2gb apart, which the jit couldn't
195 handle and barfed. now it's just a bit slower on gentoo and similar
196 systems.
197
1986.01 Sun Jul 3 12:31:14 CEST 2011
199 - workarounds are good, but the test for whether pthreads are used
200 was not good. this one should be better.
201 - check differently whether gcc generates cfi instructions itself.
202
2036.0 Wed Jun 29 19:43:35 CEST 2011
204 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
205 destroyed and cleaned up automatically (e.g. async { schedule }).
206 - implement a JIT compiler for part of the thread switch code,
207 which gives a 50% speed improvement on threaded perls, and
208 about 4% on non-threaded perls (so threaded perls now finally
209 reach about half the speed of non-threaded perls).
210 - slightly modernise Coro::Intro, add section about rouse functions.
211 - avoid DEFSV and ERRSV, giving another 10% improvement
212 in thread switching.
213 - Coro::State->is_destroyed is now called is_zombie.
214 - implement a Coro->safe_cancel method that might fail, but
215 cancels in a "safer" way if it succeeds.
216 - add preliminary support for DEBUGGING perls.
217 - get rid of two hash-accesses when initialising a new Coro - this
218 speeds up coro creation by almost a factor of two.
219 - croak when a coro that is being cancelled tries to block
220 (e.g. while executing a guard block), instead of crashing or
221 deadlocking.
222 - use a more robust and also faster method to identify Coro::State
223 objects - speeds up everything a bit.
224 - implement Coro->cancel in XS for a 20% speed improvement, and to
225 be able to implement mutual cancellation.
226 - speed up context switches by a percent or two by more efficiently
227 allocating context stack entries.
228 - implement Coro->join and Coro->on_destroy in XS for a speedup and
229 a reduction in memory use.
230 - cancelling a coro while it itself is cancelling another coro is
231 now supported and working, instead of triggering an assertion.
232 - be a bit more crash-resistant when calling (buggy) on_destroy
233 callbacks (best effort).
234 - move on_destroy into the slf_frame, to allow extension slf
235 functions to have destructors.
236 - get rid if coro refcounting - simply crash in other interpreter
237 threads by nulling the pointers on clone.
238 - simplify warn/die hook handling when loading Coro - the convoluted
239 logic seems to be no longer neccessary.
240 - use libecb instead of our own home-grown gcc hacks.
241 - document alternatives to Coro::LWP. Please use them :)
242 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
243 sigaltstack. Really. wine suffers from it, erlang suffers from it,
244 and it's known since at least 2006.
245
2465.372 Wed Feb 23 06:14:30 CET 2011
247 - apparently mingw doesn't provide a working gettimeofday, try to
248 work around that by relying on Time::HiRes (indirectly brought to
249 my attention by Max Maischein).
250 - fix some portability issues when Time::HiRes was used.
251
2525.371 Mon Feb 21 14:36:08 CET 2011
253 - backport to windows process emulation code again.
254
2555.37 Sat Feb 19 07:49:44 CET 2011
256 - add a big "Coro thread life cycle" section to "man Coro".
257 - try a tentative workaround against the breakage that 5.13 has
258 introduced without depreciation period. sigh.
259 - no longer use Time::HiRes if gettimeofday is available, which
260 saves quite a lot of memory.
261
2625.36 Sun Feb 13 05:33:41 CET 2011
263 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
264 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
265 method call.
266 - undocument Coro::Timer::sleep and obsolete whole module.
267 - optimise Coro::Timer::timeout memory and cpu usage.
268 - slightly updated Coro::Intro for recent changes.
269 - do not initialise PL_dirty anymore.
270
2715.25 Thu Nov 11 01:08:39 CET 2010
272 - try a different approach on netbsd - netbsd 5 finally has marginally
273 working pthreads, but still broken ucontext/sigaltstack.
274 - openbsd 4.8 finally got their act together, Coro works out of the box
275 with asm, setjmp and pthreads (no change, just informational).
276
2775.24 Sat Oct 23 11:27:12 CEST 2010
278 - port to the EV 4.0 API.
279 - work around bugs in mingw32, making strawberry perl work
280 out of the box.
281 - correctly modify Coro::AIO function prototypes
282 so that they reflect the "no optional parameters" rule.
283 - "ported" libcoro to C++.
284
2855.23 Mon May 17 18:50:42 CEST 2010
286 - be more resistant to ordering changes when initialising
287 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
288 Waldorf).
289 - document that perl 5.12 deliberately removed support for cloning.
290
2915.22 Wed Apr 14 03:55:35 CEST 2010
292 - correctly return udnef on errors in Coro::Handle::read/write
293 (testcase by Marc Mims).
294 - convert Coro::Util into a "perl compatibility wrapper" - the functions
295 are less useful now, but are drop-in replacements for existing
296 functions, listing better alternatives in the documentation. This also
297 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
298 with Coro::Util::inet_aton.
299 - do not override $Coro::idle unconditionally in Coro.pm, as other
300 modules could have provided their own idle coro already
301 (for exmaple, Coro::AnyEvent).
302 - fix Coro::Util::gethost* functions.
303 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
304
3055.21 Wed Dec 16 07:19:51 CET 2009
306 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
307 together.
308 - add some examples on how to combine other event loops with Coro in
309 Coro::AnyEvent, and how to run it (and not to block). Seems to be
310 the most common source of confusion.
311 - try to catch people naively blocking in an event callback.
312 - work around the perl filehandle bug issue in conjunction with
313 older common::sense (as indirectly pointed out by ZSystem).
314 - clarify the "not from signal handlers" section.
315
3165.2 Sun Oct 4 14:54:24 CEST 2009
317 - Coro::Storable destroyed the prototypes of the functions it wrapped.
318 - export rouse_cb and rouse_wait by default now.
319 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
320 - new method $state->swap_sv.
321 - added section on "windows process emulation" to the manpage,
322 after a not-so-fruitful (nor-friendly) "discussion" with chip
323 salzenberg (discussion implies arguments, but his only arguments
324 were ad-hominems, one wonders why he started it in the first
325 place). I hope this explains it well enough for him to understand,
326 and maybe well enough for others to understand.
327 - use common::sense everywhere now.
328 - idle callbacks are no longer supported, use idle coros instead.
329 - print a thread listing when a deadlock is detected.
330
3315.17 Sat Aug 22 23:09:31 CEST 2009
332 - work around a bug in the perl debugger causing crashes
333 when running under the debugger by marking _pool_handler as nodebug.
334 - speed up Coro::async considerably.
335 - try some hacks to get netbsd to work "more often" - their broken
336 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
337 - convert Coro to AE 5.0 API.
338
3395.162 Tue Jul 28 04:04:03 CEST 2009
340 - perl 5.8.2 is now minimum requirement.
341 - skip t/19_handle.t on broken windows perls.
342
3435.161 Wed Jul 22 04:47:38 CEST 2009
344 - Coro::AnyEvent::poll could have a different prototype when EV was
345 used as backend (analyzed by Tatsuhiko Miyagawa).
346 - Coro::AnyEvent errornously initialised the event loop when loaded,
347 not on demand.
348 - try to workaround rare */t/01_unblock.t failures.
349
3505.16 Tue Jul 21 01:44:37 CEST 2009
351 - Coro::AnyEvent failed to hook into the event loop
352 when no threads had been readied between detecting
353 the event loop and actually running it.
354 - considerably speed up Coro::Select by taking avdantage
355 of AnyEvent > 4.8 and some other optimisations.
356 - implement paragraph readline mode in Coro::Handle
357 (based on patches by Zsbán Ambrus).
358 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
359 and analyzed by Yasuhiro MATSUMOTO).
360 - clarified libcoro license and copyright.
361 - someone stole my EXTRA_META!!!
362 - implement Coro::Select::patch_pp_sselect and it's brother,
363 for hardcode select overriding.
364
3655.151 Mon Jul 6 05:41:57 CEST 2009
366 - backport to windows process emulation code again (patch by
367 Yasuhiro MATSUMOTO).
368 - slightly update Coro::MakeMaker.
369
3705.15 Tue Jun 30 10:28:06 CEST 2009
371 - deprecate Coro::Socket, document how to get ipv6 support via
372 AnyEvent::Socket instead.
373 - implement signal->wait ($cb) interface, similar to semaphores.
374 - work around SvOK not supporting getmagic, so we have to getmagic
375 to test for undef :/ (reported by Matthias Waldorf).
376 - load Coro::AnyEvent in all modules using AnyEvent.
377 - work around perl corrupting our internal data structures,
378 reported by Tokuhiro Matsuno.
379 - enable per-coroutine real and cpu time gathering
380 (Coro::State::enable_times).
381
3825.14 Wed Jun 24 01:37:48 CEST 2009
383 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
384 as this seems to have been a difficult concept (poll, sleep, idle,
385 idle_upto).
386 - add Coro::AnyEvent::readable/writable functions.
387 - clarify Coro::EV/Event/AnyEvent manpages.
388 - free per-thread global scalars in the thread calling ->cancel, to
389 avoid crashes when $_, $@ etc., are magical but some of those
390 had already been freed.
391 - "unexperimentalise" the callback interface for Coro::Semaphore.
392 - speed up ready queue management/context switching by using a linked
393 list instead of an array (~5-10%).
394 - implement "watch" command in Coro::Debug shells.
395 - for fun, implement time-slicing as an example in the manpage.
396 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
397 Coro::Event, use the normal AnyEvent handling instead of dieing
398 (the same is true for Coro::Handle).
399 - properly document Coro::EV::timed_io_once.
400 - avoid unneccessary ->cancel calls in Coro::Handle.
401 - maybe make it work on mingw32 with win32 backend
402 (based on patch by Yasuhiro Matsumoto).
403
4045.132 Fri May 29 09:00:39 CEST 2009
405 - do not keep a reference to the argument itself in
406 Coro::Semaphore::guard, as it could change later.
407 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
408 should support a prepare callback.
409
4105.131 Mon Mar 16 23:20:37 CET 2009
411 - implement and document Coro->suspend, Coro->resume.
412 - fix Coro::Select implementation to not (often) close
413 the passed file descriptors (testcase provided by pippijn).
414
4155.13 Mon Dec 15 21:51:42 CET 2008
416 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
417 - don't set diehook to C<undef> but instead to NULL, to avoid
418 spurious warnings.
419 - fix a lot of bugs in Coro::SemaphoreSet.
420 - Coro::SemaphoreSet will less often create a semaphore needlessly.
421 - add Coro::SemaphoreSet::count and wait methods.
422 - take advantage of the new Guard module.
423 - deprecate Coro::guard.
424 - try to fix the dreaded 01_unblock tests once more. I hate it when
425 testsuites need more fixing than the code they are supposed to test.
426 - croak in more cases when a required callback isn't resolvable.
427 - fix some minor issues in Coro::State->call/eval.
428 - use current coroutine context instead of a temporary one
429 when temporarily switching to another coroutine.
430 - do not call C-level on_destroy handlers during global destruction,
431 to avoid needless segfaults.
432
4335.12 Sun Dec 7 13:30:38 CET 2008
434 - add default config for MirOS, which seems to be a bug-to-bug
435 compatible fork of openbsd ("world domination by releasing
436 openbsd cvs before the openbsd folks do it" or so :).
437 - free_padlist did destroy the names pad, not good, but didn't
438 seem to bother perl - this could fix issues such as eval ""
439 inside a function called from multiple coroutines.
440 - use a different method to detect destruction time.
441 - be more careful when freeing padlists just before global
442 destruction.
443 - fixed and expanded the call/cc example.
444 - renamed _terminate to _coro_run.
445 - new method Coro::Channel->shutdown.
446 - try pthreads on openbsd <4.4 (broken sigaltstack, will
447 pthreads fare better?).
448 - be less picky about destroying "a" running coroutine.

451 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
452 working code with failed assertions, introducing more bugs than
453 it fixes, requiring elaborate workarounds :(
454
4555.1 Mon Nov 24 08:54:59 CET 2008
456 - wrote a small introductory tutorial - Coro::Intro.
457 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
458 - Coro::Select did errornously dup the file descriptors
459 and didn't work with all AnyEvent backends.
460 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
461 LWP data transfers.
462 - disassociate c contexts from coro objects - this is agruably more
463 correct, but mostly allows sharing of cctxs between coro and state
464 objects, for added memory savings and speed increases.
465 - bumped $Coro::POOL_RSS up to 32kb by default.
466 - no longer set the optype to OP_CUSTOM, as B::* understandably
467 doesn't like this very much (and we *are* a type of entersub).
468 - implement state cloning, just to prove that call/cc can be done.
469 - automatically load Coro::AnyEvent in Coro::Handle.
470 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
471 do not have this method (and don't need it either).
472 - speed up generic anyevent methods in Coro::Handle by using rouse
473 callbacks.
474 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
475 others. It also makes the debugger happier, as you can trace
476 through the idle threads now.
477 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
478 - eg/event was pretty broken.
479 - better 5.8.6 compatibility.
480
4815.0 Thu Nov 20 10:35:05 CET 2008
482 - NEW ARCHITECTURE: use the latest 4.x version if you experience
483 stability issues.
484 - bump API version to 7 - all dependents must be recompiled.
485 - removed timed_* functions - they were not being used anyways
486 and should be replaced by a more generic mechanism -
487 and were annoying to support anyways :)
488 - removed SemaphoreSet's waiter method - use sem method instead.
489 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
490 - async_pool did free a scalar value twice
491 ("Attempt to unreference...").
492 - fix a longstanding bug where calling terminate on a coro that
493 was waiting for a semaphore that was just becoming available
494 would cause a deadlock (semaphore would get into a state where
495 it was available but waiters were still blocked).
496 - calling throw on a coroutine that is waiting for a semaphore will
497 no longer make it acquire the semaphore (and thus leak a count).
498 - perl's process emulation is now not even theoretically supported
499 anymore.
500 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
501 conversion of callback-style to blocking-style.
502 - new methods $coro->schedule_to and ->cede_to, to specifically
503 schedule or cede to a specific coroutine.
504 - new function Coro::Semaphore::wait.
505 - use named constants in Coro::Channel (Richard Hundt).
506 - directly patch the entersub opcode calling SLF functions (cede,
507 transfer and so on). this does speed up context switching, but
508 more importanly, it frees us from the hardcoded behaviour of
509 entersub, so we might actually be able to return something from
510 those functions and atcually create new ones.
511 - take advantage of __builtin_frame_address on gcc.
512 - expose THX in coroapi (not sure whether this was a wise decision,
513 as "threaded" perls are running at half speed anyways).
514 - implement execute_slf (schedule-like-function) interface that makes
515 it possible to implement schedule-like-functions in XS.
516 - use new SLF interface to massively speed up Coro::EV by roughly a
517 factor of two.
518 - used new SLF interface to massively speed up Coro::Semaphore by a
519 factor of three.
520 - used new SLF interface to speed up Coro::AIO by roughly a factor of
521 four and reduce its memory usage considerably.
522 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
523 for a nice speedup and vastly more correct behaviour. Also implement
524 a new method "sem" to get at the underlying semaphore object.
525 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
526 (in comparison) 20-40% speedup.
527 - used new SLF interface to reimplement Coro::Signal gaining
528 some unknown (because I was too lazy), but certain, speedup, and also
529 making signals reliable for the first time.
530 - used new SLF interface and other optimisations to speed up async_pool
531 by a factor of two. It also doesn't rely on perl's exception mechanism
532 to exit anymore. The overhead for terminating an async_pool, coro over
533 a normal async is now very small.
534 - sped up coroutine creation/destruction by 40%.
535 - forgot to include Coro/libcoro/README in the dist for all these years.
536 - work around a freebsd pthreads bug (manual testcancel is required as
537 pthread_cond_wait isn't a cancellation point on freebsd).
538 - use new rouse functions to speed up and simplify Coro::BDB.
539 - make "prefer perl native functions" work with threaded perls.
540 - condense Coro::Debug ps output, hint at v and w flags.
541 - (libcoro) lots of minor cleanups and portability improvements.

5434.914 Wed Nov 19 12:54:18 CET 2008
544 - fix a disastrous bug in the readline optimisation
545 introduced in 4.801.
