3TODO: check wether stack-sharing is still effective 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: more effective stack sharing by having one "default stack" for "simple" coroutines? 4TODO: maybe implement a default message channel, very much like Erlang's
5TODO: verify exception frame changes and force stack copies? 5 actor model (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).

84.744 Tue Jul 8 22:06:35 CEST 2008
9 - correctly provide default DIE/WARN handlers as documented.
10 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
11 implementations inside perl work fine for us.
12
134.743 Mon Jun 16 00:21:57 CEST 2008
14 - when using Coro::EV without running EV::loop it could
15 result in busy-waiting for events, this has been fixed.
16 - reduce codesize and improve performance by using EV_DEFAULT_UC.
17
184.742 Sat May 31 14:10:21 CEST 2008
19 - implement a workaround for (some) perl <5.8.8 versions.
20 - require EV 3.3+.
21
224.741 Fri May 30 23:33:09 CEST 2008
23 - tell netbsd how utterly broken their imitation of an OS is
24 and refuse to build by default if pthreads are in use.
25 - switch to "s" method on all bsd's by default, as their ucontext
26 stuff seems just too broken.
27 - fix a bug in Coro::Select.
28
294.74 Thu May 29 20:05:31 CEST 2008
30 - do not test Coro::LWP for lack of dependencies.
31 - do not test Coro::Select for lack of working perls.
32
334.73 Thu May 29 2008
34 - fix a bug in Coro::EV which would cause it to block despite
35 there being runnable coroutines.
36 - sprinkle "no warnings" freely over everything, also suppress
37 warnings for some other modules.
38 - fix typo in WSAEWOULDBLOCK.
39
404.72 Sun May 25 05:14:36 CEST 2008
41 - tweak META.yaml a bit, unfortunately, there is no documented way
42 to have optional dependencies with CPAN. doh :(
43 - avoid running some tests on windows because they would fail due to
44 perl bug (broken fork, broken pipes...).
45 - work around perl on windows bugs where perl returns undocumented
46 error codes for sysread, syswrite etc. by taking advantage
47 of AnyEvent's workaround for that problem.
48 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
49 a common perl implementation bug on windows.
50 - use unix domain sockets in testsuite to work around
51 common perl implementation bugs on widows (they are emulated by
52 tcp sockets on windows. ugh.)
53
544.71 Sat May 24 20:01:27 CEST 2008
55 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
56 - take advantage of async name resolution of AnyEvent::Util.
57 - work around brutal inet_aton override in Coro::LWP.
58 - take advantage of the readyhook in Coro::EV, for smoother
59 scheduling.
60
614.7 Sun May 11 00:32:19 CEST 2008
62 - completely reworked the Coro manpage.
63 - added Coro::AnyEvent, generic event loop integration.
64 - implement cancel, ready and kill commands in Coro::Debug.
65 - document find_coro in Coro::Debug.
66 - incompatible change: rename has_stack to has_cctx.
67 - Coro::AIO and Coro::BDB no longer force event model detection,
68 use AnyEvent::AIO and AnyEvent::BDB.
69
704.6 Sat Apr 26 10:05:14 CEST 2008
71 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
72 by the Coro module. It was a mistake to have it in the first place.
73 - (experimental) support for activestate perl 5.10 (method "w").
74 - (experimental) support for strawberry perl (method "a").
75 - coro_sigelem_set did not return a value although it had to,
76 actual impact unknown.
77
784.51 Mon Apr 14 13:28:27 CEST 2008
79 - make it compile again on 5.8.
80
814.50 Thu Apr 10 09:43:17 CEST 2008
82 - I did it twice! (see 4.49).
83
844.49 Sun Apr 6 21:23:31 CEST 2008
85 - grr, instead of compiling the recent changes on 5.10 only they
86 were compiled on 5.8 only.
87
884.48 Sun Apr 6 20:36:46 CEST 2008
89 - allow coroutine switches during eval's under 5.10.x, as it seems
90 the parser is a per-interpreter option now, so this is safe
91 (this might fix the odd crashing bug).
92 - drop support for 5.9.x versions: they are dead, jim.
93
944.47 Sun Apr 6 00:37:52 CEST 2008
95 - force cctx allocation on API calls: we know we need to force one
96 and gcc actually manages to confuse our heuristic nowadays,
97 leading to crashes and worse.
98 - document force_cctx.
99
1004.46 Fri Apr 4 22:05:43 CEST 2008
101 - upgrade libcoro, resulting in pthread-backend (which was only created
102 to fulfill the rules of the programming languages shootout).
103
1044.45 Thu Mar 13 11:55:36 CET 2008
105 - fix a file leaking bug in eg/mhyttpd that would allow
106 downloading of any file (reported by oesi).
107 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
108 (also add testcase).
109 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
110 apparently having loads of fun with that).
111 - implement $state->swap_defsv, ->swap_defav and document ->throw.
112
1134.4 Wed Feb 13 16:44:29 CET 2008
114 - only assume .cfi pseudo isns exist on GNU/Linux.
115 - add get_timed method to Coro::Channels.
116 - fixed Coro::Debug manpage.
117 - perl 5.11 compatbility improvement based on patch by
118 Andreas König.
119
1204.37 Sun Jan 20 11:25:23 CET 2008
121 - soften the check for an active parser for perl 5.10 (avoiding
122 "Coro::State::transfer called while parsing" in many cases).
123
1244.36 Sun Jan 13 10:53:56 CET 2008
125 - reset diehook when terminating from an async_pool as to not
126 trigger any __DIE__ handlers.
127
1284.35 Sun Jan 13 04:14:13 CET 2008
129 - "bt" debug command now displays any exceptions
130 from longmess and also skips the innermost
131 stackframes, giving more useufl output.
132 - allow backtraces in coroutines blocked in Coro::EV,
133 at a <1% speed hit.
134 - handle localising of $SIG{__WARN__} and __DIE__
135 properly (with a proper amount of dirty hacking).
136
1374.34 Sat Dec 22 17:49:53 CET 2007
138 - upgrade to EV version 2.0 API.
139
1404.33 Mon Dec 17 08:36:12 CET 2007
141 - make Coro::AIO etc. loadable in the absence of EV.
142
1434.32 Mon Dec 17 07:46:02 CET 2007
144 - majorly improved Coro::Handle's performance with Coro::EV.
145 - implemented the until now mythical Coro::BDB module.
146 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
147
1484.31 Wed Dec 5 12:32:39 CET 2007
149 - remove warn statement form Coro::Util.
150
1514.3 Tue Dec 4 20:33:14 CET 2007
152 - calls to the idle function could cause stack corruption
153 when the stack changed.
154 - do no longer rely on the presence of EV::DNS if EV is used
155 (because it is gone), but instead take avdantage of EV::ADNS
156 if available.
157 - add ($) prototypes to all functions in Coro::Storable.
158 - use a conventional (safer) idle callback in Coro::EV.
159 - do accept quickly in Coro::Debug to avoid endless loops.
160
1614.22 Fri Nov 30 16:04:04 CET 2007
162 - really use optimised versions for Event and EV in Coro::Util
163 and Coro::Handle.
164
1654.21 Sun Nov 25 10:48:59 CET 2007
166 - fix a spurious memory read.
167 - Coro::EV no longer keeps the eventloop "alive".
168
1694.2 Fri Nov 9 20:47:05 CET 2007
170 - enable/disable tracing from a new coroutine, not a pooled one.
171 - fix a memleak in Coro::Event.
172 - removed killall call from fork_eval.
173 - made sure store_fd is already loaded so that fork_eval
174 does not have to parse autoload in each subprocess.
175 - only use assembly method if -O switch is in $Config{optimize}.
176 - add (optional) Coro::EV module, so far the best event loop module
177 directly supported by Coro.
178 - if the event model is EV, use EV::DNS to resolve
179 stuff in Coro::Util.
180 - don't get confused by multiple event notifications in Coro::Handle.
181 - initial support for EV (libevent interface).
182 - require Event and EV using configure_requires, to force their existance.
183
1844.13 Wed Oct 24 07:26:45 CEST 2007
185 - add Coro::Storable::blocking_thaw.
186 - use a vastly more complicated technique to localise
187 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
188 - use a coroutine for the idle callback Coro::Event,
189 instead of running Event in the current coroutine context.
190 This also catches recursive invocations.
191 - actually report fork errors in gethostbyname and inet_aton.
192
1934.11 Thu Oct 11 02:40:24 CEST 2007
194 - port to threaded perls.
195
1964.1 Thu Oct 11 02:38:16 CEST 2007
197 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
198 be local to each coro (see Coro::State).
199 - incompatible change: for very deep reasons, cede and cede_notself
200 cannot return anything, so nothing will be returned.
201 - possibly bring back 5.10 compatibility (untested).
202 - work around stupid (and wrong) warning on 5.10 :(.
203 - overlay the saved state over the context stack. This saves
204 a few hundred bytes per coroutine on average and also
205 speeds up context switching a bit.
206 - further tune default stack sizes.
207 - (more) correctly calculate stack usage in coro_rss.
208 - Coro::Storable::blocking_* did not properly lock
209 resulting in races between coroutines.
210 - added Coro::Storable::guard.
211 - stopping to trace a coroutine could destroy the cctx of
212 an unrelated coroutine.
213 - explain the relationship between Perl and C coroutines in
214 more detail in Coro::State.
215 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
216 causing a fork per resolve. This also affected Coro::Socket.
217 - switch to a separate stack in $coro->call/eval to avoid
218 invalidating pointers.
219
2204.03 Sat Oct 6 21:24:00 CEST 2007
221 - added Coro::throw method.
222 - minor code cleanups.
223
2244.02 Sat Oct 6 02:36:47 CEST 2007
225 - fix a very minor per-coroutine memleak (a single codereference).
226 - fixed a bug where the currently in-use c context would be freed
227 prematurely (can happen only when programs change the stacksize
228 or use tracing).
229 - tracing can no longer keep a coro alive after it terminated.
230 - do static branch prediction in the common path for gcc. gives
231 about 2-5% speed improvement here.
232
2334.01 Fri Oct 5 22:10:49 CEST 2007
234 - instead of recreating *a* standard output handle we simply
235 use STDOUT, which is faster and hopefully more robust.
236
2374.0 Fri Oct 5 12:56:00 CEST 2007
238 - incompatibly changed Coro::Storable::freeze.
239 - major new feature: added Coro::Debug, for interactive coroutine
240 debugging, tracing and much more.
241 - major bug fix: unbelievable, but true: $_, $/ and many other
242 "saved" variables actually weren't being saved. This has been fixed,
243 of course, while increasing performance while losing all the save
244 flags.
245 - save flags are gone, and all the api functions dealing with them.
246 - added Coro::Semaphore::adjust.
247 - added Coro::Util::fork_eval.
248 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
249 - added Coro::killall.
250 - reduce initial stack sizes to allow for "micro-coroutines".
251 - better async_pool resource management, moved parts of async_pool
252 handling to XS (major speed improvement).
253 - actually croak before modifying important data structures.
254 - refuse to transfer while compiling.
255 - possibly support eval EXPR better now.
256 - enable assembly per default on linux+bsd x86+amd64.
257 - all internal members were renamed _something for easier subclassing.
258 - many minor tweaks.
259
2603.63 Wed May 16 14:10:06 CEST 2007
261 - implement handcoded assembly for x86/amd64 SVR ABI.
262
2633.62 Fri Apr 27 21:36:06 CEST 2007
264 - upgrade libcoro (which might set unwind info correctly).
265 - change default on linux to setjmp/longjmp.
266
2673.61 Thu Apr 19 12:36:18 CEST 2007
268 - Coro::Storable caused an endless loop when thawing invalid
269 pst's sometimes.
270 - use a Semaphore in Coro::Storable, as Storable doesn't
271 seem to be reentrant (although it is documented to
272 be threadsafe...).
273 - fix Coro::Signal to bring back the original unreliable
274 but stateful semantics.
275 - fixed a lot of typos in Coro.pm (patch submitted by David
276 Steinbrunner, which applied flawlessly).
277
2783.6 Sat Apr 14 17:13:31 CEST 2007
279 - added some bugfixes to get eg/myhttpd working again.
280 - added Coro::Storable for often-cede'ing freeze/thaw.
281 - try to do a clean exit when a coroutine calls exit
282 (EXPERIMENTAL).
283 - got rid of indirect call through _coro_init.
284 - updated the partly antique examples in eg/ to
285 work again and be a bit less magic, too.
286 - fixed Coro::Signal semantics to work as documented again.
287
2883.55 Sun Mar 25 01:20:47 CET 2007
289 - add SAVE_DEFFH to save the default filehandle and enable
290 it by default.
291 - finally move socket-operations from Coro::Socket to Coro::Handle
292 to be able to unblock foreign sockets.
293 - add Coro::State::save_also and guarded_save.
294 - add count accessor to Coro::Semaphore.
295 - add Coro::State::cctx_stacksize.
296 - just for the fun of it, do not rely on implicit context,
297 which can dramatically improve performance, but people
298 using windows-process-emulation perls do not care much about
299 performance.
300
3013.51 Sun Mar 4 14:18:04 CET 2007
302 - fixed a problem when you weakened references to Coro::State's
303 (patch by Yuval Kogman).
304
3053.501 Wed Feb 28 12:44:07 CET 2007
306 - rename some global symbols as macosx from hell redefines
307 them without asking.
308
3093.5 Tue Feb 13 20:22:53 CET 2007
310 - do AnyEvent model detection earlier, avoiding problems
311 caused by first using AnyEvent and later Coro::Event.
312 - implement and document Coro::Event event objects.
313 - fix a potential problem in Coro::Event causing crashes.
314 - initialise PL_comppad when creating a new coroutine,
315 avoids crashes on early coro destruction.
316
3173.41 Mon Jan 22 19:19:49 CET 2007
318 - readline on Coro::Handle did not support undefined $/,
319 nor did it deliver partial lines on EOF or error.
320 - implement malloc fallback for stack allocation because
321 stupid broken idiotic OSX has a stupid broken
322 idiotic fits-the-whole-os mmap "implementation" and
323 my dick feels longer if Coro is portable even to
324 obsolete platforms.
325
3263.4 Fri Jan 19 21:52:54 CET 2007
327 - remove t/09_timer.t, as it isn't really testing much
328 but was rather flaky in practise.
329 - async_pool coro would keep arguments and callback alive until
330 it was reused.
331 - cancellation of a coroutine could cause spurious idle calls
332 in cede_notself.
333
3343.3 Sat Jan 6 03:45:00 CET 2007
335 - implement $coro->on_destroy.
336 - Coro::Event blocking semantics have been changed,
337 documented and - hopefully - improved.
338 - fix nice adding, not subtracting, from priority.
339 - fix ->prio and api_is_ready (patch by Mark Hinds).
340 - fixed an assert ("... == prev__cctx->idle_te")
341 that could errronously trigger.
342 - fix various large and small memleaks.
343 - use a (hopefully) more stable cancel implementation
344 that immediately frees the coroutine data.
345 - cede/cede_notself return a status now.
346 - added Coro::guard function.
347 - added a global coroutine pool for jobs (on my machine,
348 I can create and execute 48k simple coros/s with async,
349 and 128k coros with async_pool).
350 - Coro::AIO now uses the coroutine priority as io priority.
351
3523.2 Fri Dec 22 05:07:09 CET 2006
353 - improve portability to slightly older perls.
354 - use cleaner coroutine destruction.
355 - simplify configuration for users.
356 - optionally (unrecommended) prefer perl functions over
357 their coro replacements.
358
3593.11 Tue Dec 5 13:11:24 CET 2006
360 - fixed some bogus assert's, but as perl.h disables assert even
361 without NDEBUG (thank you very much), not too many people should
362 notice (that did include myself). Andreas König noticed, though :)
363 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
364 it. Also noticed by Andreas König :)
365 - save/restore tainted status.
366 - verified to pass the testsuite on my 5.9.5.
367
3683.1 Mon Dec 4 23:03:40 CET 2006
369 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
370 - incompatible change: transfer flags are now per-state.
371 - give a better error message on deadlock.
372 - document Coro::nready.
373 - enhanced testsuite.
374
3753.01 Sun Dec 3 23:47:42 CET 2006
376 - forgot to include Coro::Timer.
377
3783.0 Sun Dec 3 22:57:25 CET 2006
379 - the "FINALLY COMPLETELY STABLE" release (coming soon:
380 the "FAMOUS LAST WORDS" release).
7 - reimplement a new stack sharing algorithm. 381 - implement a new stack sharing algorithm, which uses a stack
382 pool (size currently hardcoded).
8 - make stack sharing mandatory (it no longer uses a heuristic). 383 - make stack sharing mandatory (it no longer uses a heuristic).
384 - eval/die no longer cause weird problems under heavy use.
9 - Coro::Event could cause livelocks if it was used but 385 - Coro::Event could cause livelocks if it was used but
10 Event watchers were used directly. 386 no Coro::Event watchers were used.
387 - Coro::Event now uses asynccheck as prepare does not
388 check for changed watchers.
389 - Coro::Event allows multiple waiting coros and will wake up one
390 per event.
11 - Coro::Event should be cleaner and more efficient now. 391 - Coro::Event should be cleaner and more efficient now.
392 - new utility function Coro::unblock_sub.
393 - document the sad fact that Event is no longer reentrant.
394 - putting a coroutine into the ready queue twice could under
395 some circumstances lead to stack corruption.
12 - minor incompatibility: subclassing is supported directly now 396 - minor incompatibility: subclassing Coro::State is supported
13 without going through a _coro_state member. 397 directly now without going through a _coro_state member.
14 - process swicthing is much faster now. 398 - state/coro switching is much faster now.
15 - very minor optimisations and code/documentation cleanup. 399 - very minor optimisations and code/documentation cleanup.
16 - avoid problems due to compiler inlining. 400 - avoid problems due to compiler inlining.
17 - possibly better support for threads.
18 - removed timers from Coro::Timer -> use AnyEvent instead. 401 - removed timers from Coro::Timer -> use AnyEvent instead.
19 - replaced Coro::idle coroutine by (cleaner) idle handler. 402 - replaced Coro::idle coroutine by (cleaner) idle handler.
403 - updated to newest libcoro.
404 - implement enhanced support for valgrind.
405 - implement is_ready and return value for ready.
406 - removed Coro::Cont, it was a misnomer (it's generators),
407 and it was somewhat annoying to get it right. Will come back
408 if somebody asks for it :)
409 - many ->wait methods and Coro::Event could return
410 spuriously without the event having happened.

212.5 Tue Nov 7 12:22:33 CET 2006 4122.5 Tue Nov 7 12:22:33 CET 2006
22 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket 413 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
23 use AnyEvent, moved them to Coro/. 414 use AnyEvent, moved them to Coro/.
