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?

10TODO: Coro::Semaphore 126.39 Mon Jun 2 00:00:08 CEST 2014
11TODO: trow disturbs cleanup path inside pp_slf? 13 - work around more incompatible changes in 5.20.
12TODO: throw special-case in transfer? 14
135.0 156.38 Sun Jun 1 21:54:23 CEST 2014
16 - check that perl slots actually have enough space to hold
17 interpreter variables.
18 - untested port to perl 5.19 (64 bit tmps indices) (reported
19 by Andreas König).
20 - croak when cancel is called without a thread context.
21
226.37 Tue Mar 4 13:27:33 CET 2014
23 - *sigh*, removed leftover debugging code from debugging a
24 perl bug, of all things.
25
266.36 Tue Mar 4 07:11:59 CET 2014
27 - semaphores would not clear the destroy hook when interrupted
28 by ->throw, causing segfaults or worse.
29 - ->throw on a thread waiting for a semaphore did not acquire
30 the semaphore, but also didn't wake up other waiters,
31 possibly causing a deadlock.
32 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
33 to report a full stacktrace, which should help find out
34 where the actual call is.
35 - "atomically" destroy data in slf_destroy, because it is
36 the right thing to do, just in case.
37 - disable ecb.h libm dependency, to compile on ancient systems
38 or under adverse conditions.
39
406.33 Mon Nov 18 11:26:27 CET 2013
41 - do not crash when freeing padlists with holes (in 5.18).
42 - tentative SVt_BIND 5.19 port/fix.
43
446.32 Tue Nov 5 15:35:35 CET 2013
45 - use a new algorithm to derive padlists for perl 5.18. The old
46 one could lead to 0-pointer accesses inside perl (reported
47 by Darin McBride).
48
496.31 Thu May 9 07:39:48 CEST 2013
50 - Coro::AIO requests would crash if the thread was ready'd
51 while the request was ongoing.
52
536.29 Wed May 8 02:55:18 CEST 2013
54 - when an on_destroy handler destructs the coro currently being
55 destructed a perl scalar could be accessed after being freed,
56 likely causing a crash.
57
586.28 Wed Mar 6 06:58:02 CET 2013
59 - clean remnants of existing __DIE__ and __WARN__ handlers so
60 they lose their magic and will not cause segfaults later
61 (testcase by Andrey Sagulin).
62 - improved Coro::State documentation a bit.
63 - Coro::Debug::command now flushes the output.
64 - add hack detection code for x32 abi, because the braindead slugs
65 who designed that made it look exactly like x86_64 without
66 providing proper compile time symbols to test for it. as a result,
67 this detection cannot work reliably.
68 - valgrind stack registering was broken.
69 - do not rely on Time::HiRes anymore in Coro::Debug.
70
716.23 Fri Dec 7 23:36:37 CET 2012
72 - use experimental fiber implementation on native windows
73 perls.
74 - use sizeof (void *) as multiplication factor for stack sizes,
75 to accomodate the totally braindamaged microsoft 64 bit "os".
76 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
77 activeperl 5.16 crashes when PerlIO_define_layer is called due
78 to some bug in the perl dll, strawberry perl at least passes
79 the testsuite.
80 - implement Coro::Handle->peeraddr/host/port, for slightly
81 improved compatibility with LWP.
82 - implement 5.17 compatibility by almost blindly applying a
83 good-looking patch by Father Chrysostomos.
84 - move stack management functions into libcoro 3.
85 - libcoro version 3 "released".
86 - support magic values as timed_io_once args.
87 - recommend AnyEvent 7+ or EV 4+, also require EV
88 version 4 or newer for Coro::EV.
89
906.10 Tue Oct 9 01:14:27 CEST 2012
91 - updated ecb.h, it had a typo that caused it to not compile on many
92 big endian systems (reported by many people).
93 - disable memory fences in ecb.h to improve portability.
94
956.09 Sat Oct 6 23:25:02 CEST 2012
96 - Coro::EV I/O watchers were not interruptible by exceptions
97 (Coro::State::throw) (testcase by sten).
98 - ->throw now puts threads into the ready queue, as this seems to
99 be expected by existing code, and code that doesn't cope with spurious
100 wakeups needs fixing anyway.
101 - use fd -1 in mmap.
102 - cast I32 to int in error message printf.
103 - warn about broken so-called "hardened" kernels.
104
1056.08 Fri Apr 13 12:05:47 CEST 2012
106 - be more aggressive about exiting like perl does - formerly,
107 exiting from the non-main thread would not execute END blocks.
108
1096.07 Fri Nov 11 21:21:48 CET 2011
110 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
111 - update ecb.h.
112
1136.06 Mon Aug 8 23:59:48 CEST 2011
114 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
115 backend, which is an order of magnitude slower. unfortunately, cygwins
116 pthread implementation isn't very complete either, so allocate the stack
117 twice just to be sure.
118 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
119 in its ithreaded perl - best recompile cygwin and use the 'w'indows
120 backend for much better performance. also disable ithreads for
121 even better performance...).
122
1236.05 Thu Aug 4 21:36:36 CEST 2011
124 - blush, condvar values would not be propagated from send to recv anymore
125 (reported by Chip Salzenberg).
126 - use exponential increase for the readline buffer length in
127 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
128
1296.04 Wed Aug 3 17:15:45 CEST 2011
130 - use even more efficient and more compatible condvars for
131 compatibility to AnyEvent 6.x :)
132 - more inconsequential ecb.h updates.
133
1346.03 Wed Aug 3 11:41:30 CEST 2011
135 - change how Coro patches AnyEvent condvars for compatibility to
136 AnyEvent 6.x.
137 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
138 hasn't been included.
139
1406.02 Wed Jul 13 04:35:19 CEST 2011
141 - "improve portability to Gentoo" - gentoo manages to put perl variables
142 in memory areas that are farther than 2gb apart, which the jit couldn't
143 handle and barfed. now it's just a bit slower on gentoo and similar
144 systems.
145
1466.01 Sun Jul 3 12:31:14 CEST 2011
147 - workarounds are good, but the test for whether pthreads are used
148 was not good. this one should be better.
149 - check differently whether gcc generates cfi instructions itself.
150
1516.0 Wed Jun 29 19:43:35 CEST 2011
152 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
153 destroyed and cleaned up automatically (e.g. async { schedule }).
154 - implement a JIT compiler for part of the thread switch code,
155 which gives a 50% speed improvement on threaded perls, and
156 about 4% on non-threaded perls (so threaded perls now finally
157 reach about half the speed of non-threaded perls).
158 - slightly modernise Coro::Intro, add section about rouse functions.
159 - avoid DEFSV and ERRSV, giving another 10% improvement
160 in thread switching.
161 - Coro::State->is_destroyed is now called is_zombie.
162 - implement a Coro->safe_cancel method that might fail, but
163 cancels in a "safer" way if it succeeds.
164 - add preliminary support for DEBUGGING perls.
165 - get rid of two hash-accesses when initialising a new Coro - this
166 speeds up coro creation by almost a factor of two.
167 - croak when a coro that is being cancelled tries to block
168 (e.g. while executing a guard block), instead of crashing or
169 deadlocking.
170 - use a more robust and also faster method to identify Coro::State
171 objects - speeds up everything a bit.
172 - implement Coro->cancel in XS for a 20% speed improvement, and to
173 be able to implement mutual cancellation.
174 - speed up context switches by a percent or two by more efficiently
175 allocating context stack entries.
176 - implement Coro->join and Coro->on_destroy in XS for a speedup and
177 a reduction in memory use.
178 - cancelling a coro while it itself is cancelling another coro is
179 now supported and working, instead of triggering an assertion.
180 - be a bit more crash-resistant when calling (buggy) on_destroy
181 callbacks (best effort).
182 - move on_destroy into the slf_frame, to allow extension slf
183 functions to have destructors.
184 - get rid if coro refcounting - simply crash in other interpreter
185 threads by nulling the pointers on clone.
186 - simplify warn/die hook handling when loading Coro - the convoluted
187 logic seems to be no longer neccessary.
188 - use libecb instead of our own home-grown gcc hacks.
189 - document alternatives to Coro::LWP. Please use them :)
190 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
191 sigaltstack. Really. wine suffers from it, erlang suffers from it,
192 and it's known since at least 2006.
193
1945.372 Wed Feb 23 06:14:30 CET 2011
195 - apparently mingw doesn't provide a working gettimeofday, try to
196 work around that by relying on Time::HiRes (indirectly brought to
197 my attention by Max Maischein).
198 - fix some portability issues when Time::HiRes was used.
199
2005.371 Mon Feb 21 14:36:08 CET 2011
201 - backport to windows process emulation code again.
202
2035.37 Sat Feb 19 07:49:44 CET 2011
204 - add a big "Coro thread life cycle" section to "man Coro".
205 - try a tentative workaround against the breakage that 5.13 has
206 introduced without depreciation period. sigh.
207 - no longer use Time::HiRes if gettimeofday is available, which
208 saves quite a lot of memory.
209
2105.36 Sun Feb 13 05:33:41 CET 2011
211 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
212 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
213 method call.
214 - undocument Coro::Timer::sleep and obsolete whole module.
215 - optimise Coro::Timer::timeout memory and cpu usage.
216 - slightly updated Coro::Intro for recent changes.
217 - do not initialise PL_dirty anymore.
218
2195.25 Thu Nov 11 01:08:39 CET 2010
220 - try a different approach on netbsd - netbsd 5 finally has marginally
221 working pthreads, but still broken ucontext/sigaltstack.
222 - openbsd 4.8 finally got their act together, Coro works out of the box
223 with asm, setjmp and pthreads (no change, just informational).
224
2255.24 Sat Oct 23 11:27:12 CEST 2010
226 - port to the EV 4.0 API.
227 - work around bugs in mingw32, making strawberry perl work
228 out of the box.
229 - correctly modify Coro::AIO function prototypes
230 so that they reflect the "no optional parameters" rule.
231 - "ported" libcoro to C++.
232
2335.23 Mon May 17 18:50:42 CEST 2010
234 - be more resistant to ordering changes when initialising
235 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
236 Waldorf).
237 - document that perl 5.12 deliberately removed support for cloning.
238
2395.22 Wed Apr 14 03:55:35 CEST 2010
240 - correctly return udnef on errors in Coro::Handle::read/write
241 (testcase by Marc Mims).
242 - convert Coro::Util into a "perl compatibility wrapper" - the functions
243 are less useful now, but are drop-in replacements for existing
244 functions, listing better alternatives in the documentation. This also
245 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
246 with Coro::Util::inet_aton.
247 - do not override $Coro::idle unconditionally in Coro.pm, as other
248 modules could have provided their own idle coro already
249 (for exmaple, Coro::AnyEvent).
250 - fix Coro::Util::gethost* functions.
251 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
252
2535.21 Wed Dec 16 07:19:51 CET 2009
254 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
255 together.
256 - add some examples on how to combine other event loops with Coro in
257 Coro::AnyEvent, and how to run it (and not to block). Seems to be
258 the most common source of confusion.
259 - try to catch people naively blocking in an event callback.
260 - work around the perl filehandle bug issue in conjunction with
261 older common::sense (as indirectly pointed out by ZSystem).
262 - clarify the "not from signal handlers" section.
263
2645.2 Sun Oct 4 14:54:24 CEST 2009
265 - Coro::Storable destroyed the prototypes of the functions it wrapped.
266 - export rouse_cb and rouse_wait by default now.
267 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
268 - new method $state->swap_sv.
269 - added section on "windows process emulation" to the manpage,
270 after a not-so-fruitful (nor-friendly) "discussion" with chip
271 salzenberg (discussion implies arguments, but his only arguments
272 were ad-hominems, one wonders why he started it in the first
273 place). I hope this explains it well enough for him to understand,
274 and maybe well enough for others to understand.
275 - use common::sense everywhere now.
276 - idle callbacks are no longer supported, use idle coros instead.
277 - print a thread listing when a deadlock is detected.
278
2795.17 Sat Aug 22 23:09:31 CEST 2009
280 - work around a bug in the perl debugger causing crashes
281 when running under the debugger by marking _pool_handler as nodebug.
282 - speed up Coro::async considerably.
283 - try some hacks to get netbsd to work "more often" - their broken
284 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
285 - convert Coro to AE 5.0 API.
286
2875.162 Tue Jul 28 04:04:03 CEST 2009
288 - perl 5.8.2 is now minimum requirement.
289 - skip t/19_handle.t on broken windows perls.
290
2915.161 Wed Jul 22 04:47:38 CEST 2009
292 - Coro::AnyEvent::poll could have a different prototype when EV was
293 used as backend (analyzed by Tatsuhiko Miyagawa).
294 - Coro::AnyEvent errornously initialised the event loop when loaded,
295 not on demand.
296 - try to workaround rare */t/01_unblock.t failures.
297
2985.16 Tue Jul 21 01:44:37 CEST 2009
299 - Coro::AnyEvent failed to hook into the event loop
300 when no threads had been readied between detecting
301 the event loop and actually running it.
302 - considerably speed up Coro::Select by taking avdantage
303 of AnyEvent > 4.8 and some other optimisations.
304 - implement paragraph readline mode in Coro::Handle
305 (based on patches by Zsbán Ambrus).
306 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
307 and analyzed by Yasuhiro MATSUMOTO).
308 - clarified libcoro license and copyright.
309 - someone stole my EXTRA_META!!!
310 - implement Coro::Select::patch_pp_sselect and it's brother,
311 for hardcode select overriding.
312
3135.151 Mon Jul 6 05:41:57 CEST 2009
314 - backport to windows process emulation code again (patch by
315 Yasuhiro MATSUMOTO).
316 - slightly update Coro::MakeMaker.
317
3185.15 Tue Jun 30 10:28:06 CEST 2009
319 - deprecate Coro::Socket, document how to get ipv6 support via
320 AnyEvent::Socket instead.
321 - implement signal->wait ($cb) interface, similar to semaphores.
322 - work around SvOK not supporting getmagic, so we have to getmagic
323 to test for undef :/ (reported by Matthias Waldorf).
324 - load Coro::AnyEvent in all modules using AnyEvent.
325 - work around perl corrupting our internal data structures,
326 reported by Tokuhiro Matsuno.
327 - enable per-coroutine real and cpu time gathering
328 (Coro::State::enable_times).
329
3305.14 Wed Jun 24 01:37:48 CEST 2009
331 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
332 as this seems to have been a difficult concept (poll, sleep, idle,
333 idle_upto).
334 - add Coro::AnyEvent::readable/writable functions.
335 - clarify Coro::EV/Event/AnyEvent manpages.
336 - free per-thread global scalars in the thread calling ->cancel, to
337 avoid crashes when $_, $@ etc., are magical but some of those
338 had already been freed.
339 - "unexperimentalise" the callback interface for Coro::Semaphore.
340 - speed up ready queue management/context switching by using a linked
341 list instead of an array (~5-10%).
342 - implement "watch" command in Coro::Debug shells.
343 - for fun, implement time-slicing as an example in the manpage.
344 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
345 Coro::Event, use the normal AnyEvent handling instead of dieing
346 (the same is true for Coro::Handle).
347 - properly document Coro::EV::timed_io_once.
348 - avoid unneccessary ->cancel calls in Coro::Handle.
349 - maybe make it work on mingw32 with win32 backend
350 (based on patch by Yasuhiro Matsumoto).
351
3525.132 Fri May 29 09:00:39 CEST 2009
353 - do not keep a reference to the argument itself in
354 Coro::Semaphore::guard, as it could change later.
355 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
356 should support a prepare callback.
357
3585.131 Mon Mar 16 23:20:37 CET 2009
359 - implement and document Coro->suspend, Coro->resume.
360 - fix Coro::Select implementation to not (often) close
361 the passed file descriptors (testcase provided by pippijn).
362
3635.13 Mon Dec 15 21:51:42 CET 2008
364 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
365 - don't set diehook to C<undef> but instead to NULL, to avoid
366 spurious warnings.
367 - fix a lot of bugs in Coro::SemaphoreSet.
368 - Coro::SemaphoreSet will less often create a semaphore needlessly.
369 - add Coro::SemaphoreSet::count and wait methods.
370 - take advantage of the new Guard module.
371 - deprecate Coro::guard.
372 - try to fix the dreaded 01_unblock tests once more. I hate it when
373 testsuites need more fixing than the code they are supposed to test.
374 - croak in more cases when a required callback isn't resolvable.
375 - fix some minor issues in Coro::State->call/eval.
376 - use current coroutine context instead of a temporary one
377 when temporarily switching to another coroutine.
378 - do not call C-level on_destroy handlers during global destruction,
379 to avoid needless segfaults.
380
3815.12 Sun Dec 7 13:30:38 CET 2008
382 - add default config for MirOS, which seems to be a bug-to-bug
383 compatible fork of openbsd ("world domination by releasing
384 openbsd cvs before the openbsd folks do it" or so :).
385 - free_padlist did destroy the names pad, not good, but didn't
386 seem to bother perl - this could fix issues such as eval ""
387 inside a function called from multiple coroutines.
388 - use a different method to detect destruction time.
389 - be more careful when freeing padlists just before global
390 destruction.
391 - fixed and expanded the call/cc example.
392 - renamed _terminate to _coro_run.
393 - new method Coro::Channel->shutdown.
394 - try pthreads on openbsd <4.4 (broken sigaltstack, will
395 pthreads fare better?).
396 - be less picky about destroying "a" running coroutine.
397
3985.11 Tue Nov 25 21:49:05 CET 2008
399 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
400 working code with failed assertions, introducing more bugs than
401 it fixes, requiring elaborate workarounds :(
402
4035.1 Mon Nov 24 08:54:59 CET 2008
404 - wrote a small introductory tutorial - Coro::Intro.
405 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
406 - Coro::Select did errornously dup the file descriptors
407 and didn't work with all AnyEvent backends.
408 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
409 LWP data transfers.
410 - disassociate c contexts from coro objects - this is agruably more
411 correct, but mostly allows sharing of cctxs between coro and state
412 objects, for added memory savings and speed increases.
413 - bumped $Coro::POOL_RSS up to 32kb by default.
414 - no longer set the optype to OP_CUSTOM, as B::* understandably
415 doesn't like this very much (and we *are* a type of entersub).
416 - implement state cloning, just to prove that call/cc can be done.
417 - automatically load Coro::AnyEvent in Coro::Handle.
418 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
419 do not have this method (and don't need it either).
420 - speed up generic anyevent methods in Coro::Handle by using rouse
421 callbacks.
422 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
423 others. It also makes the debugger happier, as you can trace
424 through the idle threads now.
425 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
426 - eg/event was pretty broken.
427 - better 5.8.6 compatibility.
428
4295.0 Thu Nov 20 10:35:05 CET 2008
14 - NEW ARCHITECTURE: use the latest 4.x version if you experience 430 - NEW ARCHITECTURE: use the latest 4.x version if you experience
15 stability issues. 431 stability issues.
16 - bump API version to 7 - all dependents must be recompiled. 432 - bump API version to 7 - all dependents must be recompiled.
433 - removed timed_* functions - they were not being used anyways
434 and should be replaced by a more generic mechanism -
435 and were annoying to support anyways :)
436 - removed SemaphoreSet's waiter method - use sem method instead.
17 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 437 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
18 - async_pool did free a scalar value twice 438 - async_pool did free a scalar value twice

24 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 444 - calling throw on a coroutine that is waiting for a semaphore will
445 no longer make it acquire the semaphore (and thus leak a count).

451 schedule or cede to a specific coroutine.

470 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
471 for a nice speedup and vastly more correct behaviour. Also implement
472 a new method "sem" to get at the underlying semaphore object.
473 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
474 (in comparison) 20-40% speedup.
475 - used new SLF interface to reimplement Coro::Signal gaining
476 some unknown (because I was too lazy), but certain, speedup, and also
477 making signals reliable for the first time.
478 - used new SLF interface and other optimisations to speed up async_pool
479 by a factor of two. It also doesn't rely on perl's exception mechanism
480 to exit anymore. The overhead for terminating an async_pool, coro over
481 a normal async is now very small.
