2 2
3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
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)).

84.802 Thu Oct 30 10:56:12 CET 2008
9 - support -fno-omit-frame-pointer on x86 with the assembly method.
10 - tune 01_unblock.t tests a bit.
11
124.801 Wed Oct 22 18:33:37 CEST 2008
13 - improve readline speed for very long "lines".
14 - backport to 5.8.8.
15
164.8 Thu Oct 2 13:34:40 CEST 2008
17 - new function Coro::AIO::aio_wait.
18 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
19 - greatly speed up and reduce memory usage of Coro::AIO requests.
20 - implement some other µ-optimisations.
21
224.749 Mon Sep 29 14:40:12 CEST 2008
23 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
24
254.748 Sat Sep 27 14:03:19 CEST 2008
26 - implement, but do not document, PerlIO::cede(granularity).
27 - Coro::Storable forgot to wrap Storable::pstore.
28 - work around the multitude of leaks and memory corruption
29 bugs in PerlIO::via by using our own C-level perliol. As a side
30 effect, Coro::Storable is now much, much, much faster.
31
324.747 Tue Sep 23 01:59:41 CEST 2008
33 - fix a per-cv memleak (one empty array was leaked per
34 code reference).
35 - avoid a crash in coro->call|rss when the coroutine was already
36 destroyed (most noticably when using Coro::Debug::ps :)
37 - also protect *Storable::FILE.
38 - push up default storable granularity to 20ms.
39
404.746 Sun Sep 21 03:22:20 CEST 2008
41 - be more insistent on locking Storable against reentrancy
42 in Coro::Storable.
43 - move swap_def?v and throw to Coro::State, as documented.
44
454.745 Thu Jul 24 00:14:38 CEST 2008
46 - remove debugging code related to MgPV_nolen_const, also try to
47 make it compile with perl 5.8.6 (yes, apple apparently loves
48 outdated software). Reported by John S.
49
504.744 Tue Jul 8 22:06:35 CEST 2008
51 - correctly provide default DIE/WARN handlers as documented.
52 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
53 implementations inside perl work fine for us.
54
554.743 Mon Jun 16 00:21:57 CEST 2008
56 - when using Coro::EV without running EV::loop it could
57 result in busy-waiting for events, this has been fixed.
58 - reduce codesize and improve performance by using EV_DEFAULT_UC.
59
604.742 Sat May 31 14:10:21 CEST 2008
61 - implement a workaround for (some) perl <5.8.8 versions.
62 - require EV 3.3+.
63
644.741 Fri May 30 23:33:09 CEST 2008
65 - tell netbsd how utterly broken their imitation of an OS is
66 and refuse to build by default if pthreads are in use.
67 - switch to "s" method on all bsd's by default, as their ucontext
68 stuff seems just too broken.
69 - fix a bug in Coro::Select.
70
714.74 Thu May 29 20:05:31 CEST 2008
72 - do not test Coro::LWP for lack of dependencies.
73 - do not test Coro::Select for lack of working perls.
74
754.73 Thu May 29 2008
76 - fix a bug in Coro::EV which would cause it to block despite
77 there being runnable coroutines.
78 - sprinkle "no warnings" freely over everything, also suppress
79 warnings for some other modules.
80 - fix typo in WSAEWOULDBLOCK.
81
824.72 Sun May 25 05:14:36 CEST 2008
83 - tweak META.yaml a bit, unfortunately, there is no documented way
84 to have optional dependencies with CPAN. doh :(
85 - avoid running some tests on windows because they would fail due to
86 perl bug (broken fork, broken pipes...).
87 - work around perl on windows bugs where perl returns undocumented
88 error codes for sysread, syswrite etc. by taking advantage
89 of AnyEvent's workaround for that problem.
90 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
91 a common perl implementation bug on windows.
92 - use unix domain sockets in testsuite to work around
93 common perl implementation bugs on widows (they are emulated by
94 tcp sockets on windows. ugh.)
95
964.71 Sat May 24 20:01:27 CEST 2008
97 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
98 - take advantage of async name resolution of AnyEvent::Util.
99 - work around brutal inet_aton override in Coro::LWP.
100 - take advantage of the readyhook in Coro::EV, for smoother
101 scheduling.
102
1034.7 Sun May 11 00:32:19 CEST 2008
104 - completely reworked the Coro manpage.
105 - added Coro::AnyEvent, generic event loop integration.
106 - implement cancel, ready and kill commands in Coro::Debug.
107 - document find_coro in Coro::Debug.
108 - incompatible change: rename has_stack to has_cctx.
109 - Coro::AIO and Coro::BDB no longer force event model detection,
110 use AnyEvent::AIO and AnyEvent::BDB.
111
1124.6 Sat Apr 26 10:05:14 CEST 2008
113 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
114 by the Coro module. It was a mistake to have it in the first place.
115 - (experimental) support for activestate perl 5.10 (method "w").
116 - (experimental) support for strawberry perl (method "a").
117 - coro_sigelem_set did not return a value although it had to,
118 actual impact unknown.
119
1204.51 Mon Apr 14 13:28:27 CEST 2008
121 - make it compile again on 5.8.
122
1234.50 Thu Apr 10 09:43:17 CEST 2008
124 - I did it twice! (see 4.49).
125
1264.49 Sun Apr 6 21:23:31 CEST 2008
127 - grr, instead of compiling the recent changes on 5.10 only they
128 were compiled on 5.8 only.
129
1304.48 Sun Apr 6 20:36:46 CEST 2008
131 - allow coroutine switches during eval's under 5.10.x, as it seems
132 the parser is a per-interpreter option now, so this is safe
133 (this might fix the odd crashing bug).
134 - drop support for 5.9.x versions: they are dead, jim.
135
1364.47 Sun Apr 6 00:37:52 CEST 2008
137 - force cctx allocation on API calls: we know we need to force one
138 and gcc actually manages to confuse our heuristic nowadays,
139 leading to crashes and worse.
140 - document force_cctx.
141
1424.46 Fri Apr 4 22:05:43 CEST 2008
143 - upgrade libcoro, resulting in pthread-backend (which was only created
144 to fulfill the rules of the programming languages shootout).
145
1464.45 Thu Mar 13 11:55:36 CET 2008
147 - fix a file leaking bug in eg/mhyttpd that would allow
148 downloading of any file (reported by oesi).
149 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
150 (also add testcase).
151 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
152 apparently having loads of fun with that).
153 - implement $state->swap_defsv, ->swap_defav and document ->throw.
154
1554.4 Wed Feb 13 16:44:29 CET 2008
156 - only assume .cfi pseudo isns exist on GNU/Linux.
157 - add get_timed method to Coro::Channels.
158 - fixed Coro::Debug manpage.
159 - perl 5.11 compatbility improvement based on patch by
160 Andreas König.
161
1624.37 Sun Jan 20 11:25:23 CET 2008
163 - soften the check for an active parser for perl 5.10 (avoiding
164 "Coro::State::transfer called while parsing" in many cases).
165
1664.36 Sun Jan 13 10:53:56 CET 2008
167 - reset diehook when terminating from an async_pool as to not
168 trigger any __DIE__ handlers.
169
1704.35 Sun Jan 13 04:14:13 CET 2008
171 - "bt" debug command now displays any exceptions
172 from longmess and also skips the innermost
173 stackframes, giving more useufl output.
174 - allow backtraces in coroutines blocked in Coro::EV,
175 at a <1% speed hit.
176 - handle localising of $SIG{__WARN__} and __DIE__
177 properly (with a proper amount of dirty hacking).
178
1794.34 Sat Dec 22 17:49:53 CET 2007
180 - upgrade to EV version 2.0 API.
181
1824.33 Mon Dec 17 08:36:12 CET 2007
183 - make Coro::AIO etc. loadable in the absence of EV.
184
1854.32 Mon Dec 17 07:46:02 CET 2007
186 - majorly improved Coro::Handle's performance with Coro::EV.
187 - implemented the until now mythical Coro::BDB module.
188 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
189
1904.31 Wed Dec 5 12:32:39 CET 2007
191 - remove warn statement form Coro::Util.
192
1934.3 Tue Dec 4 20:33:14 CET 2007
194 - calls to the idle function could cause stack corruption
195 when the stack changed.
196 - do no longer rely on the presence of EV::DNS if EV is used
197 (because it is gone), but instead take avdantage of EV::ADNS
198 if available.
199 - add ($) prototypes to all functions in Coro::Storable.
200 - use a conventional (safer) idle callback in Coro::EV.
201 - do accept quickly in Coro::Debug to avoid endless loops.
202
2034.22 Fri Nov 30 16:04:04 CET 2007
204 - really use optimised versions for Event and EV in Coro::Util
205 and Coro::Handle.
206
2074.21 Sun Nov 25 10:48:59 CET 2007
208 - fix a spurious memory read.
209 - Coro::EV no longer keeps the eventloop "alive".
210
2114.2 Fri Nov 9 20:47:05 CET 2007
212 - enable/disable tracing from a new coroutine, not a pooled one.
213 - fix a memleak in Coro::Event.
214 - removed killall call from fork_eval.
215 - made sure store_fd is already loaded so that fork_eval
216 does not have to parse autoload in each subprocess.
217 - only use assembly method if -O switch is in $Config{optimize}.
218 - add (optional) Coro::EV module, so far the best event loop module
219 directly supported by Coro.
220 - if the event model is EV, use EV::DNS to resolve
221 stuff in Coro::Util.
222 - don't get confused by multiple event notifications in Coro::Handle.
223 - initial support for EV (libevent interface).
224 - require Event and EV using configure_requires, to force their existance.
225
2264.13 Wed Oct 24 07:26:45 CEST 2007
227 - add Coro::Storable::blocking_thaw.
228 - use a vastly more complicated technique to localise
229 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
230 - use a coroutine for the idle callback Coro::Event,
231 instead of running Event in the current coroutine context.
232 This also catches recursive invocations.
233 - actually report fork errors in gethostbyname and inet_aton.
234
2354.11 Thu Oct 11 02:40:24 CEST 2007
236 - port to threaded perls.
237
2384.1 Thu Oct 11 02:38:16 CEST 2007
239 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
240 be local to each coro (see Coro::State).
241 - incompatible change: for very deep reasons, cede and cede_notself
242 cannot return anything, so nothing will be returned.
243 - possibly bring back 5.10 compatibility (untested).
244 - work around stupid (and wrong) warning on 5.10 :(.
245 - overlay the saved state over the context stack. This saves
246 a few hundred bytes per coroutine on average and also
247 speeds up context switching a bit.
248 - further tune default stack sizes.
249 - (more) correctly calculate stack usage in coro_rss.
250 - Coro::Storable::blocking_* did not properly lock
251 resulting in races between coroutines.
252 - added Coro::Storable::guard.
253 - stopping to trace a coroutine could destroy the cctx of
254 an unrelated coroutine.
255 - explain the relationship between Perl and C coroutines in
256 more detail in Coro::State.
257 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
258 causing a fork per resolve. This also affected Coro::Socket.
259 - switch to a separate stack in $coro->call/eval to avoid
260 invalidating pointers.
261
2624.03 Sat Oct 6 21:24:00 CEST 2007
263 - added Coro::throw method.
264 - minor code cleanups.
265
2664.02 Sat Oct 6 02:36:47 CEST 2007
267 - fix a very minor per-coroutine memleak (a single codereference).
268 - fixed a bug where the currently in-use c context would be freed
269 prematurely (can happen only when programs change the stacksize
270 or use tracing).
271 - tracing can no longer keep a coro alive after it terminated.
272 - do static branch prediction in the common path for gcc. gives
273 about 2-5% speed improvement here.
274
2754.01 Fri Oct 5 22:10:49 CEST 2007
276 - instead of recreating *a* standard output handle we simply
277 use STDOUT, which is faster and hopefully more robust.
278
2794.0 Fri Oct 5 12:56:00 CEST 2007
280 - incompatibly changed Coro::Storable::freeze.
281 - major new feature: added Coro::Debug, for interactive coroutine
282 debugging, tracing and much more.
283 - major bug fix: unbelievable, but true: $_, $/ and many other
284 "saved" variables actually weren't being saved. This has been fixed,
285 of course, while increasing performance while losing all the save
286 flags.
287 - save flags are gone, and all the api functions dealing with them.
288 - added Coro::Semaphore::adjust.
289 - added Coro::Util::fork_eval.
290 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
291 - added Coro::killall.
292 - reduce initial stack sizes to allow for "micro-coroutines".
293 - better async_pool resource management, moved parts of async_pool
294 handling to XS (major speed improvement).
295 - actually croak before modifying important data structures.
296 - refuse to transfer while compiling.
297 - possibly support eval EXPR better now.
298 - enable assembly per default on linux+bsd x86+amd64.
299 - all internal members were renamed _something for easier subclassing.
300 - many minor tweaks.
301
3023.63 Wed May 16 14:10:06 CEST 2007
303 - implement handcoded assembly for x86/amd64 SVR ABI.
304
3053.62 Fri Apr 27 21:36:06 CEST 2007
306 - upgrade libcoro (which might set unwind info correctly).
307 - change default on linux to setjmp/longjmp.
308
3093.61 Thu Apr 19 12:36:18 CEST 2007
310 - Coro::Storable caused an endless loop when thawing invalid
311 pst's sometimes.
312 - use a Semaphore in Coro::Storable, as Storable doesn't
313 seem to be reentrant (although it is documented to
314 be threadsafe...).
315 - fix Coro::Signal to bring back the original unreliable
316 but stateful semantics.
317 - fixed a lot of typos in Coro.pm (patch submitted by David
318 Steinbrunner, which applied flawlessly).
319
3203.6 Sat Apr 14 17:13:31 CEST 2007
321 - added some bugfixes to get eg/myhttpd working again.
322 - added Coro::Storable for often-cede'ing freeze/thaw.
323 - try to do a clean exit when a coroutine calls exit
324 (EXPERIMENTAL).
325 - got rid of indirect call through _coro_init.
326 - updated the partly antique examples in eg/ to
327 work again and be a bit less magic, too.
328 - fixed Coro::Signal semantics to work as documented again.
329
3303.55 Sun Mar 25 01:20:47 CET 2007
331 - add SAVE_DEFFH to save the default filehandle and enable
332 it by default.
333 - finally move socket-operations from Coro::Socket to Coro::Handle
334 to be able to unblock foreign sockets.
335 - add Coro::State::save_also and guarded_save.
336 - add count accessor to Coro::Semaphore.
337 - add Coro::State::cctx_stacksize.
338 - just for the fun of it, do not rely on implicit context,
339 which can dramatically improve performance, but people
340 using windows-process-emulation perls do not care much about
341 performance.
342
3433.51 Sun Mar 4 14:18:04 CET 2007
344 - fixed a problem when you weakened references to Coro::State's
345 (patch by Yuval Kogman).
346
3473.501 Wed Feb 28 12:44:07 CET 2007
348 - rename some global symbols as macosx from hell redefines
349 them without asking.
350
3513.5 Tue Feb 13 20:22:53 CET 2007
352 - do AnyEvent model detection earlier, avoiding problems
353 caused by first using AnyEvent and later Coro::Event.
354 - implement and document Coro::Event event objects.
355 - fix a potential problem in Coro::Event causing crashes.
356 - initialise PL_comppad when creating a new coroutine,
357 avoids crashes on early coro destruction.
358
3593.41 Mon Jan 22 19:19:49 CET 2007
360 - readline on Coro::Handle did not support undefined $/,
361 nor did it deliver partial lines on EOF or error.
362 - implement malloc fallback for stack allocation because
363 stupid broken idiotic OSX has a stupid broken
364 idiotic fits-the-whole-os mmap "implementation" and
365 my dick feels longer if Coro is portable even to
366 obsolete platforms.
367
3683.4 Fri Jan 19 21:52:54 CET 2007
369 - remove t/09_timer.t, as it isn't really testing much
370 but was rather flaky in practise.
371 - async_pool coro would keep arguments and callback alive until
372 it was reused.
373 - cancellation of a coroutine could cause spurious idle calls
374 in cede_notself.
375
3763.3 Sat Jan 6 03:45:00 CET 2007
5 - implement $coro->on_destroy. 377 - implement $coro->on_destroy.
6 - Coro::Event blocking semantics have been changed, 378 - Coro::Event blocking semantics have been changed,
7 documented and - hopefully - improved. 379 documented and - hopefully - improved.
8 - fix nice adding, not subtracting, from priority. 380 - fix nice adding, not subtracting, from priority.
9 - fix ->prio and api_is_ready (patch by Mark Hinds). 381 - fix ->prio and api_is_ready (patch by Mark Hinds).
382 - fixed an assert ("... == prev__cctx->idle_te")
383 that could errronously trigger.
384 - fix various large and small memleaks.
385 - use a (hopefully) more stable cancel implementation
386 that immediately frees the coroutine data.
387 - cede/cede_notself return a status now.
388 - added Coro::guard function.
389 - added a global coroutine pool for jobs (on my machine,
390 I can create and execute 48k simple coros/s with async,
391 and 128k coros with async_pool).
392 - Coro::AIO now uses the coroutine priority as io priority.
10 393
113.2 Fri Dec 22 05:07:09 CET 2006 3943.2 Fri Dec 22 05:07:09 CET 2006
12 - improve portability to slightly older perls. 395 - improve portability to slightly older perls.
13 - use cleaner coroutine destruction. 396 - use cleaner coroutine destruction.
14 - simplify configuration for users. 397 - simplify configuration for users.
