2 2
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)). 6
7TODO: unready_all 7 - croak when a coro being cancelled tries to block (e.g. while
8TODO: myhttpd header parsing 8 executing a guard block), instead of crashing or deadlocking.
9 - implement a Coro->safe_cancel method that might fail, but
10 cancels in a "safer" way if it succeeds.
11 - implement Coro->cancel in XS for a 20% speed improvement, and to
12 be able to implement mutual cancellation.
13 - speed up context switches by a percent or two by more efficiently
14 allocating context stack entries.
15 - cancelling a coro while it itself is cancelling another coro is
16 now supported and working, instead of triggering an assertion.
17 - be a bit more crash-resistant when calling (buggy) on_destroy
18 callbacks (best effort).
19 - move on_destroy into the slf_frame, to allow extension slf
20 functions to have destructors.

225.372 Wed Feb 23 06:14:30 CET 2011
23 - apparently mingw doesn't provide a working gettimeofday, try to
24 work around that by relying on Time::HiRes (indirectly brought to
25 my attention by Max Maischein).
26 - fix some portability issues when Time::HiRes was used.
27
285.371 Mon Feb 21 14:36:08 CET 2011
29 - backport to windows process emulation code again.
30
315.37 Sat Feb 19 07:49:44 CET 2011
32 - add a big "Coro thread life cycle" section to "man Coro".
33 - try a tentative workaround against the breakage that 5.13 has
34 introduced without depreciation period. sigh.
35 - no longer use Time::HiRes if gettimeofday is available, which
36 saves quite a lot of memory.
37
385.36 Sun Feb 13 05:33:41 CET 2011
39 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
40 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
41 method call.
42 - undocument Coro::Timer::sleep and obsolete whole module.
43 - optimise Coro::Timer::timeout memory and cpu usage.
44 - slightly updated Coro::Intro for recent changes.
45 - do not initialise PL_dirty anymore.
46
475.25 Thu Nov 11 01:08:39 CET 2010
48 - try a different approach on netbsd - netbsd 5 finally has marginally
49 working pthreads, but still broken ucontext/sigaltstack.
50 - openbsd 4.8 finally got their act together, Coro works out of the box
51 with asm, setjmp and pthreads (no change, just informational).
52
535.24 Sat Oct 23 11:27:12 CEST 2010
54 - port to the EV 4.0 API.
55 - work around bugs in mingw32, making strawberry perl work
56 out of the box.
57 - correctly modify Coro::AIO function prototypes
58 so that they reflect the "no optional parameters" rule.
59 - "ported" libcoro to C++.
60
615.23 Mon May 17 18:50:42 CEST 2010
62 - be more resistant to ordering changes when initialising
63 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
64 Waldorf).
65 - document that perl 5.12 deliberately removed support for cloning.
66
675.22 Wed Apr 14 03:55:35 CEST 2010
68 - correctly return udnef on errors in Coro::Handle::read/write
69 (testcase by Marc Mims).
70 - convert Coro::Util into a "perl compatibility wrapper" - the functions
71 are less useful now, but are drop-in replacements for existing
72 functions, listing better alternatives in the documentation. This also
73 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
74 with Coro::Util::inet_aton.
75 - do not override $Coro::idle unconditionally in Coro.pm, as other
76 modules could have provided their own idle coro already
77 (for exmaple, Coro::AnyEvent).
78 - fix Coro::Util::gethost* functions.
79 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
80
815.21 Wed Dec 16 07:19:51 CET 2009
82 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
83 together.
84 - add some examples on how to combine other event loops with Coro in
85 Coro::AnyEvent, and how to run it (and not to block). Seems to be
86 the most common source of confusion.
87 - try to catch people naively blocking in an event callback.
88 - work around the perl filehandle bug issue in conjunction with
89 older common::sense (as indirectly pointed out by ZSystem).
90 - clarify the "not from signal handlers" section.
91
925.2 Sun Oct 4 14:54:24 CEST 2009
93 - Coro::Storable destroyed the prototypes of the functions it wrapped.
94 - export rouse_cb and rouse_wait by default now.
95 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
96 - new method $state->swap_sv.
97 - added section on "windows process emulation" to the manpage,
98 after a not-so-fruitful (nor-friendly) "discussion" with chip
99 salzenberg (discussion implies arguments, but his only arguments
100 were ad-hominems, one wonders why he started it in the first
101 place). I hope this explains it well enough for him to understand,
102 and maybe well enough for others to understand.
103 - use common::sense everywhere now.
104 - idle callbacks are no longer supported, use idle coros instead.
105 - print a thread listing when a deadlock is detected.
106
1075.17 Sat Aug 22 23:09:31 CEST 2009
108 - work around a bug in the perl debugger causing crashes
109 when running under the debugger by marking _pool_handler as nodebug.
110 - speed up Coro::async considerably.
111 - try some hacks to get netbsd to work "more often" - their broken
112 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
113 - convert Coro to AE 5.0 API.
114
1155.162 Tue Jul 28 04:04:03 CEST 2009
116 - perl 5.8.2 is now minimum requirement.
117 - skip t/19_handle.t on broken windows perls.
118
1195.161 Wed Jul 22 04:47:38 CEST 2009
120 - Coro::AnyEvent::poll could have a different prototype when EV was
121 used as backend (analyzed by Tatsuhiko Miyagawa).
122 - Coro::AnyEvent errornously initialised the event loop when loaded,
123 not on demand.
124 - try to workaround rare */t/01_unblock.t failures.
125
1265.16 Tue Jul 21 01:44:37 CEST 2009
127 - Coro::AnyEvent failed to hook into the event loop
128 when no threads had been readied between detecting
129 the event loop and actually running it.
130 - considerably speed up Coro::Select by taking avdantage
131 of AnyEvent > 4.8 and some other optimisations.
132 - implement paragraph readline mode in Coro::Handle
133 (based on patches by Zsbán Ambrus).
134 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
135 and analyzed by Yasuhiro MATSUMOTO).
136 - clarified libcoro license and copyright.
137 - someone stole my EXTRA_META!!!
138 - implement Coro::Select::patch_pp_sselect and it's brother,
139 for hardcode select overriding.
140
1415.151 Mon Jul 6 05:41:57 CEST 2009
142 - backport to windows process emulation code again (patch by
143 Yasuhiro MATSUMOTO).
144 - slightly update Coro::MakeMaker.
145
1465.15 Tue Jun 30 10:28:06 CEST 2009
147 - deprecate Coro::Socket, document how to get ipv6 support via
148 AnyEvent::Socket instead.
149 - implement signal->wait ($cb) interface, similar to semaphores.
150 - work around SvOK not supporting getmagic, so we have to getmagic
151 to test for undef :/ (reported by Matthias Waldorf).
152 - load Coro::AnyEvent in all modules using AnyEvent.
153 - work around perl corrupting our internal data structures,
154 reported by Tokuhiro Matsuno.
155 - enable per-coroutine real and cpu time gathering
156 (Coro::State::enable_times).
157
1585.14 Wed Jun 24 01:37:48 CEST 2009
159 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
160 as this seems to have been a difficult concept (poll, sleep, idle,
161 idle_upto).
162 - add Coro::AnyEvent::readable/writable functions.
163 - clarify Coro::EV/Event/AnyEvent manpages.
164 - free per-thread global scalars in the thread calling ->cancel, to
165 avoid crashes when $_, $@ etc., are magical but some of those
166 had already been freed.
167 - "unexperimentalise" the callback interface for Coro::Semaphore.
168 - speed up ready queue management/context switching by using a linked
169 list instead of an array (~5-10%).
170 - implement "watch" command in Coro::Debug shells.
171 - for fun, implement time-slicing as an example in the manpage.
172 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
173 Coro::Event, use the normal AnyEvent handling instead of dieing
174 (the same is true for Coro::Handle).
175 - properly document Coro::EV::timed_io_once.
176 - avoid unneccessary ->cancel calls in Coro::Handle.
177 - maybe make it work on mingw32 with win32 backend
178 (based on patch by Yasuhiro Matsumoto).

105.132 Fri May 29 09:00:39 CEST 2009 1805.132 Fri May 29 09:00:39 CEST 2009
11 - do not keep a reference to the argument itself in 181 - do not keep a reference to the argument itself in
12 Coro::Semaphore::guard, as it could change later. 182 Coro::Semaphore::guard, as it could change later.
13 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options, 183 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
