3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: maybe implement a default message channel, very much like Erlang's
5 actor model (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
7
84.745 Thu Jul 24 00:14:38 CEST 2008
9 - remove debugging code related to MgPV_nolen_const, also try to
10 make it compile with perl 5.8.6 (yes, apple apparently loves
11 outdated software). Reported by John S.
12
134.744 Tue Jul 8 22:06:35 CEST 2008
14 - correctly provide default DIE/WARN handlers as documented.
15 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
16 implementations inside perl work fine for us.
17
184.743 Mon Jun 16 00:21:57 CEST 2008
19 - when using Coro::EV without running EV::loop it could
20 result in busy-waiting for events, this has been fixed.
21 - reduce codesize and improve performance by using EV_DEFAULT_UC.
22
234.742 Sat May 31 14:10:21 CEST 2008
24 - implement a workaround for (some) perl <5.8.8 versions.
25 - require EV 3.3+.
26
274.741 Fri May 30 23:33:09 CEST 2008
28 - tell netbsd how utterly broken their imitation of an OS is
29 and refuse to build by default if pthreads are in use.
30 - switch to "s" method on all bsd's by default, as their ucontext
31 stuff seems just too broken.
32 - fix a bug in Coro::Select.
33
344.74 Thu May 29 20:05:31 CEST 2008
35 - do not test Coro::LWP for lack of dependencies.
36 - do not test Coro::Select for lack of working perls.
37
384.73 Thu May 29 2008
39 - fix a bug in Coro::EV which would cause it to block despite
40 there being runnable coroutines.
41 - sprinkle "no warnings" freely over everything, also suppress
42 warnings for some other modules.
43 - fix typo in WSAEWOULDBLOCK.
44
454.72 Sun May 25 05:14:36 CEST 2008
46 - tweak META.yaml a bit, unfortunately, there is no documented way
47 to have optional dependencies with CPAN. doh :(
48 - avoid running some tests on windows because they would fail due to
49 perl bug (broken fork, broken pipes...).
50 - work around perl on windows bugs where perl returns undocumented
51 error codes for sysread, syswrite etc. by taking advantage
52 of AnyEvent's workaround for that problem.
53 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
54 a common perl implementation bug on windows.
55 - use unix domain sockets in testsuite to work around
56 common perl implementation bugs on widows (they are emulated by
57 tcp sockets on windows. ugh.)
58
594.71 Sat May 24 20:01:27 CEST 2008
60 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
61 - take advantage of async name resolution of AnyEvent::Util.
62 - work around brutal inet_aton override in Coro::LWP.
63 - take advantage of the readyhook in Coro::EV, for smoother
64 scheduling.
65
664.7 Sun May 11 00:32:19 CEST 2008
67 - completely reworked the Coro manpage.
68 - added Coro::AnyEvent, generic event loop integration.
69 - implement cancel, ready and kill commands in Coro::Debug.
70 - document find_coro in Coro::Debug.
71 - incompatible change: rename has_stack to has_cctx.
72 - Coro::AIO and Coro::BDB no longer force event model detection,
73 use AnyEvent::AIO and AnyEvent::BDB.
74
754.6 Sat Apr 26 10:05:14 CEST 2008
76 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
77 by the Coro module. It was a mistake to have it in the first place.
78 - (experimental) support for activestate perl 5.10 (method "w").
79 - (experimental) support for strawberry perl (method "a").
80 - coro_sigelem_set did not return a value although it had to,
81 actual impact unknown.
82
834.51 Mon Apr 14 13:28:27 CEST 2008
84 - make it compile again on 5.8.
85
864.50 Thu Apr 10 09:43:17 CEST 2008
87 - I did it twice! (see 4.49).
88
894.49 Sun Apr 6 21:23:31 CEST 2008
90 - grr, instead of compiling the recent changes on 5.10 only they
91 were compiled on 5.8 only.
92
934.48 Sun Apr 6 20:36:46 CEST 2008
94 - allow coroutine switches during eval's under 5.10.x, as it seems
95 the parser is a per-interpreter option now, so this is safe
96 (this might fix the odd crashing bug).
97 - drop support for 5.9.x versions: they are dead, jim.
98
994.47 Sun Apr 6 00:37:52 CEST 2008
100 - force cctx allocation on API calls: we know we need to force one
101 and gcc actually manages to confuse our heuristic nowadays,
102 leading to crashes and worse.
103 - document force_cctx.
104
1054.46 Fri Apr 4 22:05:43 CEST 2008
106 - upgrade libcoro, resulting in pthread-backend (which was only created
107 to fulfill the rules of the programming languages shootout).
108
1094.45 Thu Mar 13 11:55:36 CET 2008
110 - fix a file leaking bug in eg/mhyttpd that would allow
111 downloading of any file (reported by oesi).
112 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
113 (also add testcase).
114 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
115 apparently having loads of fun with that).
116 - implement $state->swap_defsv, ->swap_defav and document ->throw.
117
1184.4 Wed Feb 13 16:44:29 CET 2008
119 - only assume .cfi pseudo isns exist on GNU/Linux.
120 - add get_timed method to Coro::Channels.
121 - fixed Coro::Debug manpage.
122 - perl 5.11 compatbility improvement based on patch by
123 Andreas König.
124
1254.37 Sun Jan 20 11:25:23 CET 2008
126 - soften the check for an active parser for perl 5.10 (avoiding
127 "Coro::State::transfer called while parsing" in many cases).
128
1294.36 Sun Jan 13 10:53:56 CET 2008
130 - reset diehook when terminating from an async_pool as to not
131 trigger any __DIE__ handlers.
132
1334.35 Sun Jan 13 04:14:13 CET 2008
134 - "bt" debug command now displays any exceptions
135 from longmess and also skips the innermost
136 stackframes, giving more useufl output.
137 - allow backtraces in coroutines blocked in Coro::EV,
138 at a <1% speed hit.
139 - handle localising of $SIG{__WARN__} and __DIE__
140 properly (with a proper amount of dirty hacking).
141
1424.34 Sat Dec 22 17:49:53 CET 2007
143 - upgrade to EV version 2.0 API.
144
1454.33 Mon Dec 17 08:36:12 CET 2007
146 - make Coro::AIO etc. loadable in the absence of EV.
147
1484.32 Mon Dec 17 07:46:02 CET 2007
149 - majorly improved Coro::Handle's performance with Coro::EV.
150 - implemented the until now mythical Coro::BDB module.
151 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
152
1534.31 Wed Dec 5 12:32:39 CET 2007
154 - remove warn statement form Coro::Util.
155
1564.3 Tue Dec 4 20:33:14 CET 2007
157 - calls to the idle function could cause stack corruption
158 when the stack changed.
159 - do no longer rely on the presence of EV::DNS if EV is used
160 (because it is gone), but instead take avdantage of EV::ADNS
161 if available.
162 - add ($) prototypes to all functions in Coro::Storable.
163 - use a conventional (safer) idle callback in Coro::EV.
164 - do accept quickly in Coro::Debug to avoid endless loops.
165
1664.22 Fri Nov 30 16:04:04 CET 2007
167 - really use optimised versions for Event and EV in Coro::Util
168 and Coro::Handle.
169
1704.21 Sun Nov 25 10:48:59 CET 2007
171 - fix a spurious memory read.
172 - Coro::EV no longer keeps the eventloop "alive".
173
1744.2 Fri Nov 9 20:47:05 CET 2007
175 - enable/disable tracing from a new coroutine, not a pooled one.
176 - fix a memleak in Coro::Event.
177 - removed killall call from fork_eval.
178 - made sure store_fd is already loaded so that fork_eval
179 does not have to parse autoload in each subprocess.
180 - only use assembly method if -O switch is in $Config{optimize}.
181 - add (optional) Coro::EV module, so far the best event loop module
182 directly supported by Coro.
183 - if the event model is EV, use EV::DNS to resolve
184 stuff in Coro::Util.
185 - don't get confused by multiple event notifications in Coro::Handle.
186 - initial support for EV (libevent interface).
187 - require Event and EV using configure_requires, to force their existance.
188
1894.13 Wed Oct 24 07:26:45 CEST 2007
190 - add Coro::Storable::blocking_thaw.
191 - use a vastly more complicated technique to localise
192 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
193 - use a coroutine for the idle callback Coro::Event,
194 instead of running Event in the current coroutine context.
195 This also catches recursive invocations.
196 - actually report fork errors in gethostbyname and inet_aton.
197
1984.11 Thu Oct 11 02:40:24 CEST 2007
199 - port to threaded perls.
200
2014.1 Thu Oct 11 02:38:16 CEST 2007
202 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
203 be local to each coro (see Coro::State).
204 - incompatible change: for very deep reasons, cede and cede_notself
205 cannot return anything, so nothing will be returned.
206 - possibly bring back 5.10 compatibility (untested).
207 - work around stupid (and wrong) warning on 5.10 :(.
208 - overlay the saved state over the context stack. This saves
209 a few hundred bytes per coroutine on average and also
210 speeds up context switching a bit.
211 - further tune default stack sizes.
212 - (more) correctly calculate stack usage in coro_rss.
213 - Coro::Storable::blocking_* did not properly lock
214 resulting in races between coroutines.
215 - added Coro::Storable::guard.
216 - stopping to trace a coroutine could destroy the cctx of
217 an unrelated coroutine.
218 - explain the relationship between Perl and C coroutines in
219 more detail in Coro::State.
220 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
221 causing a fork per resolve. This also affected Coro::Socket.
222 - switch to a separate stack in $coro->call/eval to avoid
223 invalidating pointers.
224
2254.03 Sat Oct 6 21:24:00 CEST 2007
226 - added Coro::throw method.
227 - minor code cleanups.
228
2294.02 Sat Oct 6 02:36:47 CEST 2007
230 - fix a very minor per-coroutine memleak (a single codereference).
231 - fixed a bug where the currently in-use c context would be freed
232 prematurely (can happen only when programs change the stacksize
233 or use tracing).
234 - tracing can no longer keep a coro alive after it terminated.
235 - do static branch prediction in the common path for gcc. gives
236 about 2-5% speed improvement here.
237
2384.01 Fri Oct 5 22:10:49 CEST 2007
239 - instead of recreating *a* standard output handle we simply
240 use STDOUT, which is faster and hopefully more robust.
241
2424.0 Fri Oct 5 12:56:00 CEST 2007
243 - incompatibly changed Coro::Storable::freeze.
244 - major new feature: added Coro::Debug, for interactive coroutine
245 debugging, tracing and much more.
246 - major bug fix: unbelievable, but true: $_, $/ and many other
247 "saved" variables actually weren't being saved. This has been fixed,
248 of course, while increasing performance while losing all the save
249 flags.
250 - save flags are gone, and all the api functions dealing with them.
251 - added Coro::Semaphore::adjust.
252 - added Coro::Util::fork_eval.
253 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
254 - added Coro::killall.
255 - reduce initial stack sizes to allow for "micro-coroutines".
256 - better async_pool resource management, moved parts of async_pool
257 handling to XS (major speed improvement).
258 - actually croak before modifying important data structures.
259 - refuse to transfer while compiling.
260 - possibly support eval EXPR better now.
261 - enable assembly per default on linux+bsd x86+amd64.
262 - all internal members were renamed _something for easier subclassing.
263 - many minor tweaks.
264
2653.63 Wed May 16 14:10:06 CEST 2007
266 - implement handcoded assembly for x86/amd64 SVR ABI.
267
2683.62 Fri Apr 27 21:36:06 CEST 2007
269 - upgrade libcoro (which might set unwind info correctly).
270 - change default on linux to setjmp/longjmp.
271
2723.61 Thu Apr 19 12:36:18 CEST 2007
273 - Coro::Storable caused an endless loop when thawing invalid
274 pst's sometimes.
275 - use a Semaphore in Coro::Storable, as Storable doesn't
276 seem to be reentrant (although it is documented to
277 be threadsafe...).
278 - fix Coro::Signal to bring back the original unreliable
279 but stateful semantics.
280 - fixed a lot of typos in Coro.pm (patch submitted by David
281 Steinbrunner, which applied flawlessly).
282
2833.6 Sat Apr 14 17:13:31 CEST 2007
284 - added some bugfixes to get eg/myhttpd working again.
285 - added Coro::Storable for often-cede'ing freeze/thaw.
286 - try to do a clean exit when a coroutine calls exit
287 (EXPERIMENTAL).
288 - got rid of indirect call through _coro_init.
289 - updated the partly antique examples in eg/ to
290 work again and be a bit less magic, too.
291 - fixed Coro::Signal semantics to work as documented again.
292
2933.55 Sun Mar 25 01:20:47 CET 2007
294 - add SAVE_DEFFH to save the default filehandle and enable
295 it by default.
296 - finally move socket-operations from Coro::Socket to Coro::Handle
297 to be able to unblock foreign sockets.
298 - add Coro::State::save_also and guarded_save.
299 - add count accessor to Coro::Semaphore.
300 - add Coro::State::cctx_stacksize.
301 - just for the fun of it, do not rely on implicit context,
302 which can dramatically improve performance, but people
303 using windows-process-emulation perls do not care much about
304 performance.
305
3063.51 Sun Mar 4 14:18:04 CET 2007
307 - fixed a problem when you weakened references to Coro::State's
308 (patch by Yuval Kogman).
309
3103.501 Wed Feb 28 12:44:07 CET 2007
311 - rename some global symbols as macosx from hell redefines
312 them without asking.
313
3143.5 Tue Feb 13 20:22:53 CET 2007
315 - do AnyEvent model detection earlier, avoiding problems
316 caused by first using AnyEvent and later Coro::Event.
317 - implement and document Coro::Event event objects.
318 - fix a potential problem in Coro::Event causing crashes.
319 - initialise PL_comppad when creating a new coroutine,
320 avoids crashes on early coro destruction.
321
3223.41 Mon Jan 22 19:19:49 CET 2007
323 - readline on Coro::Handle did not support undefined $/,
324 nor did it deliver partial lines on EOF or error.
325 - implement malloc fallback for stack allocation because
326 stupid broken idiotic OSX has a stupid broken
327 idiotic fits-the-whole-os mmap "implementation" and
328 my dick feels longer if Coro is portable even to
329 obsolete platforms.
330
3313.4 Fri Jan 19 21:52:54 CET 2007
332 - remove t/09_timer.t, as it isn't really testing much
333 but was rather flaky in practise.
334 - async_pool coro would keep arguments and callback alive until
335 it was reused.
336 - cancellation of a coroutine could cause spurious idle calls
337 in cede_notself.
338
3393.3 Sat Jan 6 03:45:00 CET 2007
340 - implement $coro->on_destroy.
341 - Coro::Event blocking semantics have been changed,
342 documented and - hopefully - improved.
343 - fix nice adding, not subtracting, from priority.
344 - fix ->prio and api_is_ready (patch by Mark Hinds).
345 - fixed an assert ("... == prev__cctx->idle_te")
346 that could errronously trigger.
347 - fix various large and small memleaks.
348 - use a (hopefully) more stable cancel implementation
349 that immediately frees the coroutine data.
350 - cede/cede_notself return a status now.
351 - added Coro::guard function.
352 - added a global coroutine pool for jobs (on my machine,
353 I can create and execute 48k simple coros/s with async,
354 and 128k coros with async_pool).
355 - Coro::AIO now uses the coroutine priority as io priority.
356
3573.2 Fri Dec 22 05:07:09 CET 2006
358 - improve portability to slightly older perls.
359 - use cleaner coroutine destruction.
360 - simplify configuration for users.
361 - optionally (unrecommended) prefer perl functions over
362 their coro replacements.
363
3643.11 Tue Dec 5 13:11:24 CET 2006
365 - fixed some bogus assert's, but as perl.h disables assert even
366 without NDEBUG (thank you very much), not too many people should
367 notice (that did include myself). Andreas König noticed, though :)
368 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
369 it. Also noticed by Andreas König :)
370 - save/restore tainted status.
371 - verified to pass the testsuite on my 5.9.5.
372
3733.1 Mon Dec 4 23:03:40 CET 2006
374 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
375 - incompatible change: transfer flags are now per-state.
376 - give a better error message on deadlock.
377 - document Coro::nready.
378 - enhanced testsuite.
379
3803.01 Sun Dec 3 23:47:42 CET 2006
381 - forgot to include Coro::Timer.
382
3833.0 Sun Dec 3 22:57:25 CET 2006
384 - the "FINALLY COMPLETELY STABLE" release (coming soon:
385 the "FAMOUS LAST WORDS" release).
386 - implement a new stack sharing algorithm, which uses a stack
387 pool (size currently hardcoded).
388 - make stack sharing mandatory (it no longer uses a heuristic).
389 - eval/die no longer cause weird problems under heavy use.
390 - Coro::Event could cause livelocks if it was used but
391 no Coro::Event watchers were used.
392 - Coro::Event now uses asynccheck as prepare does not
393 check for changed watchers.
394 - Coro::Event allows multiple waiting coros and will wake up one
395 per event.
396 - Coro::Event should be cleaner and more efficient now.
397 - new utility function Coro::unblock_sub.
398 - document the sad fact that Event is no longer reentrant.
399 - putting a coroutine into the ready queue twice could under
400 some circumstances lead to stack corruption.
401 - minor incompatibility: subclassing Coro::State is supported
402 directly now without going through a _coro_state member.
403 - state/coro switching is much faster now.
404 - very minor optimisations and code/documentation cleanup.
405 - avoid problems due to compiler inlining.
406 - removed timers from Coro::Timer -> use AnyEvent instead.
407 - replaced Coro::idle coroutine by (cleaner) idle handler.
408 - updated to newest libcoro.
409 - implement enhanced support for valgrind.
410 - implement is_ready and return value for ready.
411 - removed Coro::Cont, it was a misnomer (it's generators),
412 and it was somewhat annoying to get it right. Will come back
413 if somebody asks for it :)
414 - many ->wait methods and Coro::Event could return
415 spuriously without the event having happened.
416
4172.5 Tue Nov 7 12:22:33 CET 2006
418 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
419 use AnyEvent, moved them to Coro/.
420 - added Coro::LWP which contains all the uglyness required to
421 make LWP non-blocking.
422 - should work with perl 5.9.x now (Andreas König made me do it).
423 - fixed another bug in Coro::Select when the timeout was undef.
424 - reuse PL_start_env for all coros, saves some memory per coroutine.
425 - manage PL_top_env differently, hopefully to avoid panic: top_env.
426 - timeout argument was not properly used in Coro::Socket.
427 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
428 - emulate undocumented(!) functionality of IO::Socket required
429 by LWP(!!).
430 - updated eg/lwp to work with newer lwp's.
431 - remove "FATAL: uncaught exception" prefix. Coroutines that die
432 kill the whole process, just as exceptions in the main "coroutine"
433 did already.
434
4352.1 Wed Nov 1 23:01:13 CET 2006
436 - fix a long-standing bug in Coro::Select where select with
437 zero timeout would instead change the current default filehandle.
438 - use a simpler and hopefully more robust way to clone padlists
439 (uses less memory and a perl function instead of our own).
440 - coro can now create a stack guard area on many architectures.
441 - Coro::AIO properly reexports additional functions from IO::AIO.
442 - updated libcoro with a workaround for OS X,
443 pach and testing by Michael Schwern.
444
4452.0 Tue Oct 24 05:47:17 CEST 2006
446 - support additional aio requests in Coro::AIO.
447
4481.9 (never properly released due to a glitch)
449
4501.8 Thu Feb 2 00:59:06 CET 2006
451 - applied suggested patch by SAMV to avoid problems during stupid
452 mark & sweep gc run.
453 - applied patch by Scott Walters for 5.9.3 compatibility.
454
4551.7 Tue Dec 27 01:41:58 CET 2005
456 - added Coro::AIO, a thin wrapper around IO::AIO.
457 - improved Makefile.PL explanations.
458
4591.6 Mon Dec 12 21:30:05 CET 2005
460 - additionally save PM_curpm might fix as-of-yet
461 unseen problems with regex matches being attributed to the
462 wrong package.
463 - add t/10_bugs.t, which currently checks against imho broken
464 perls that use 0.26MB of stack space per Perl_magic_get
