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: http://www.microsoft.com/msj/archive/s2ce.aspx
6 but very lacking in others (higher level ipc)).
7 6
8TODO: CF_RUNNING makes sense only for Coros, not States 7TODO: tutorial
9TODO: Coro::AnyEvent should only force detect in the idle hook. 8 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
9 destroyed and cleaned up automatically (e.g. async { schedule }).
10 - Coro::State->is_destroyed is now called is_zombie.
11 - implement a Coro->safe_cancel method that might fail, but
12 cancels in a "safer" way if it succeeds.
13 - get rid of two hash-accesses when initialising a new Coro - this
14 speeds up coro creation by almost a factor of two.
15 - croak when a coro that is being cancelled tries to block
16 (e.g. while executing a guard block), instead of crashing or
17 deadlocking.
18 - use a more robust and also faster method to identify Coro::State
19 objects - speeds up everything a bit.
20 - implement Coro->cancel in XS for a 20% speed improvement, and to
21 be able to implement mutual cancellation.
22 - speed up context switches by a percent or two by more efficiently
23 allocating context stack entries.
24 - implement Coro->join and Coro->on_destroy in XS for a speedup and
25 a reduction in memory use.
26 - cancelling a coro while it itself is cancelling another coro is
27 now supported and working, instead of triggering an assertion.
28 - be a bit more crash-resistant when calling (buggy) on_destroy
29 callbacks (best effort).
30 - move on_destroy into the slf_frame, to allow extension slf
31 functions to have destructors.
32 - get rid if coro refcounting - simply crash in other interpreter
33 threads by nulling the pointers on clone.
34 - simplify warn/die hook handling when loading Coro - the convoluted
35 logic seems to be no longer neccessary.
36
375.372 Wed Feb 23 06:14:30 CET 2011
38 - apparently mingw doesn't provide a working gettimeofday, try to
39 work around that by relying on Time::HiRes (indirectly brought to
40 my attention by Max Maischein).
41 - fix some portability issues when Time::HiRes was used.
42
435.371 Mon Feb 21 14:36:08 CET 2011
44 - backport to windows process emulation code again.
45
465.37 Sat Feb 19 07:49:44 CET 2011
47 - add a big "Coro thread life cycle" section to "man Coro".
48 - try a tentative workaround against the breakage that 5.13 has
49 introduced without depreciation period. sigh.
50 - no longer use Time::HiRes if gettimeofday is available, which
51 saves quite a lot of memory.
52
535.36 Sun Feb 13 05:33:41 CET 2011
54 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
55 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
56 method call.
57 - undocument Coro::Timer::sleep and obsolete whole module.
58 - optimise Coro::Timer::timeout memory and cpu usage.
59 - slightly updated Coro::Intro for recent changes.
60 - do not initialise PL_dirty anymore.
61
625.25 Thu Nov 11 01:08:39 CET 2010
63 - try a different approach on netbsd - netbsd 5 finally has marginally
64 working pthreads, but still broken ucontext/sigaltstack.
65 - openbsd 4.8 finally got their act together, Coro works out of the box
66 with asm, setjmp and pthreads (no change, just informational).
67
685.24 Sat Oct 23 11:27:12 CEST 2010
69 - port to the EV 4.0 API.
70 - work around bugs in mingw32, making strawberry perl work
71 out of the box.
72 - correctly modify Coro::AIO function prototypes
73 so that they reflect the "no optional parameters" rule.
74 - "ported" libcoro to C++.
75
765.23 Mon May 17 18:50:42 CEST 2010
77 - be more resistant to ordering changes when initialising
78 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
79 Waldorf).
80 - document that perl 5.12 deliberately removed support for cloning.
81
825.22 Wed Apr 14 03:55:35 CEST 2010
83 - correctly return udnef on errors in Coro::Handle::read/write
84 (testcase by Marc Mims).
85 - convert Coro::Util into a "perl compatibility wrapper" - the functions
86 are less useful now, but are drop-in replacements for existing
87 functions, listing better alternatives in the documentation. This also
88 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
89 with Coro::Util::inet_aton.
90 - do not override $Coro::idle unconditionally in Coro.pm, as other
91 modules could have provided their own idle coro already
92 (for exmaple, Coro::AnyEvent).
93 - fix Coro::Util::gethost* functions.
94 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
95
965.21 Wed Dec 16 07:19:51 CET 2009
97 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
98 together.
99 - add some examples on how to combine other event loops with Coro in
100 Coro::AnyEvent, and how to run it (and not to block). Seems to be
101 the most common source of confusion.
102 - try to catch people naively blocking in an event callback.
103 - work around the perl filehandle bug issue in conjunction with
104 older common::sense (as indirectly pointed out by ZSystem).
105 - clarify the "not from signal handlers" section.
106
1075.2 Sun Oct 4 14:54:24 CEST 2009
108 - Coro::Storable destroyed the prototypes of the functions it wrapped.
109 - export rouse_cb and rouse_wait by default now.
110 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
111 - new method $state->swap_sv.
112 - added section on "windows process emulation" to the manpage,
113 after a not-so-fruitful (nor-friendly) "discussion" with chip
114 salzenberg (discussion implies arguments, but his only arguments
115 were ad-hominems, one wonders why he started it in the first
116 place). I hope this explains it well enough for him to understand,
117 and maybe well enough for others to understand.
118 - use common::sense everywhere now.
119 - idle callbacks are no longer supported, use idle coros instead.
120 - print a thread listing when a deadlock is detected.
121
1225.17 Sat Aug 22 23:09:31 CEST 2009
123 - work around a bug in the perl debugger causing crashes
124 when running under the debugger by marking _pool_handler as nodebug.
125 - speed up Coro::async considerably.
126 - try some hacks to get netbsd to work "more often" - their broken
127 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
128 - convert Coro to AE 5.0 API.
129
1305.162 Tue Jul 28 04:04:03 CEST 2009
131 - perl 5.8.2 is now minimum requirement.
132 - skip t/19_handle.t on broken windows perls.
133
1345.161 Wed Jul 22 04:47:38 CEST 2009
135 - Coro::AnyEvent::poll could have a different prototype when EV was
136 used as backend (analyzed by Tatsuhiko Miyagawa).
137 - Coro::AnyEvent errornously initialised the event loop when loaded,
138 not on demand.
139 - try to workaround rare */t/01_unblock.t failures.
140
1415.16 Tue Jul 21 01:44:37 CEST 2009
142 - Coro::AnyEvent failed to hook into the event loop
143 when no threads had been readied between detecting
144 the event loop and actually running it.
145 - considerably speed up Coro::Select by taking avdantage
146 of AnyEvent > 4.8 and some other optimisations.
147 - implement paragraph readline mode in Coro::Handle
148 (based on patches by Zsbán Ambrus).
149 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
150 and analyzed by Yasuhiro MATSUMOTO).
151 - clarified libcoro license and copyright.
152 - someone stole my EXTRA_META!!!
153 - implement Coro::Select::patch_pp_sselect and it's brother,
154 for hardcode select overriding.
155
1565.151 Mon Jul 6 05:41:57 CEST 2009
157 - backport to windows process emulation code again (patch by
158 Yasuhiro MATSUMOTO).
159 - slightly update Coro::MakeMaker.
160
1615.15 Tue Jun 30 10:28:06 CEST 2009
162 - deprecate Coro::Socket, document how to get ipv6 support via
163 AnyEvent::Socket instead.
164 - implement signal->wait ($cb) interface, similar to semaphores.
165 - work around SvOK not supporting getmagic, so we have to getmagic
166 to test for undef :/ (reported by Matthias Waldorf).
167 - load Coro::AnyEvent in all modules using AnyEvent.
168 - work around perl corrupting our internal data structures,
169 reported by Tokuhiro Matsuno.
170 - enable per-coroutine real and cpu time gathering
171 (Coro::State::enable_times).
172
1735.14 Wed Jun 24 01:37:48 CEST 2009
174 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
175 as this seems to have been a difficult concept (poll, sleep, idle,
176 idle_upto).
177 - add Coro::AnyEvent::readable/writable functions.
178 - clarify Coro::EV/Event/AnyEvent manpages.
179 - free per-thread global scalars in the thread calling ->cancel, to
180 avoid crashes when $_, $@ etc., are magical but some of those
181 had already been freed.
182 - "unexperimentalise" the callback interface for Coro::Semaphore.
183 - speed up ready queue management/context switching by using a linked
184 list instead of an array (~5-10%).
185 - implement "watch" command in Coro::Debug shells.
186 - for fun, implement time-slicing as an example in the manpage.
187 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
188 Coro::Event, use the normal AnyEvent handling instead of dieing
189 (the same is true for Coro::Handle).
190 - properly document Coro::EV::timed_io_once.
191 - avoid unneccessary ->cancel calls in Coro::Handle.
192 - maybe make it work on mingw32 with win32 backend
193 (based on patch by Yasuhiro Matsumoto).
194
1955.132 Fri May 29 09:00:39 CEST 2009
196 - do not keep a reference to the argument itself in
197 Coro::Semaphore::guard, as it could change later.
198 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
199 should support a prepare callback.
200
2015.131 Mon Mar 16 23:20:37 CET 2009
202 - implement and document Coro->suspend, Coro->resume.
203 - fix Coro::Select implementation to not (often) close
204 the passed file descriptors (testcase provided by pippijn).
205
2065.13 Mon Dec 15 21:51:42 CET 2008
207 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
208 - don't set diehook to C<undef> but instead to NULL, to avoid
209 spurious warnings.
210 - fix a lot of bugs in Coro::SemaphoreSet.
211 - Coro::SemaphoreSet will less often create a semaphore needlessly.
212 - add Coro::SemaphoreSet::count and wait methods.
213 - take advantage of the new Guard module.
214 - deprecate Coro::guard.
215 - try to fix the dreaded 01_unblock tests once more. I hate it when
216 testsuites need more fixing than the code they are supposed to test.
217 - croak in more cases when a required callback isn't resolvable.
218 - fix some minor issues in Coro::State->call/eval.
219 - use current coroutine context instead of a temporary one
220 when temporarily switching to another coroutine.
221 - do not call C-level on_destroy handlers during global destruction,
222 to avoid needless segfaults.
223
2245.12 Sun Dec 7 13:30:38 CET 2008
