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)). 6TODO: cancel calling another coro that cancels ourselves => crash (CF_DELAYCANCEL?) -> canceltest
7 7
8TODO: suspend/resume, unready_all etc. 8 - implement Coro->cancel in XS for a 20% speed improvement, and to
9 be able to implement mutual cancellation.
10 - cancelling a coro while it itself is cancelling another coro is
11 now supported and working, instead of triggering an assertion.
12 - be a bit more crash-resistant when calling (buggy) on_destroy
13 callbacks (best effort).

155.372 Wed Feb 23 06:14:30 CET 2011
16 - apparently mingw doesn't provide a working gettimeofday, try to
17 work around that by relying on Time::HiRes (indirectly brought to
18 my attention by Max Maischein).
19 - fix some portability issues when Time::HiRes was used.
20
215.371 Mon Feb 21 14:36:08 CET 2011
22 - backport to windows process emulation code again.
23
245.37 Sat Feb 19 07:49:44 CET 2011
25 - add a big "Coro thread life cycle" section to "man Coro".
26 - try a tentative workaround against the breakage that 5.13 has
27 introduced without depreciation period. sigh.
28 - no longer use Time::HiRes if gettimeofday is available, which
29 saves quite a lot of memory.
30
315.36 Sun Feb 13 05:33:41 CET 2011
32 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
33 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
34 method call.
35 - undocument Coro::Timer::sleep and obsolete whole module.
36 - optimise Coro::Timer::timeout memory and cpu usage.
37 - slightly updated Coro::Intro for recent changes.
38 - do not initialise PL_dirty anymore.
39
405.25 Thu Nov 11 01:08:39 CET 2010
41 - try a different approach on netbsd - netbsd 5 finally has marginally
42 working pthreads, but still broken ucontext/sigaltstack.
43 - openbsd 4.8 finally got their act together, Coro works out of the box
44 with asm, setjmp and pthreads (no change, just informational).
45
465.24 Sat Oct 23 11:27:12 CEST 2010
47 - port to the EV 4.0 API.
48 - work around bugs in mingw32, making strawberry perl work
49 out of the box.
50 - correctly modify Coro::AIO function prototypes
51 so that they reflect the "no optional parameters" rule.
52 - "ported" libcoro to C++.
53
545.23 Mon May 17 18:50:42 CEST 2010
55 - be more resistant to ordering changes when initialising
56 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
57 Waldorf).
58 - document that perl 5.12 deliberately removed support for cloning.
59
605.22 Wed Apr 14 03:55:35 CEST 2010
61 - correctly return udnef on errors in Coro::Handle::read/write
62 (testcase by Marc Mims).
63 - convert Coro::Util into a "perl compatibility wrapper" - the functions
64 are less useful now, but are drop-in replacements for existing
65 functions, listing better alternatives in the documentation. This also
66 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
67 with Coro::Util::inet_aton.
68 - do not override $Coro::idle unconditionally in Coro.pm, as other
69 modules could have provided their own idle coro already
70 (for exmaple, Coro::AnyEvent).
71 - fix Coro::Util::gethost* functions.
72 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
73
745.21 Wed Dec 16 07:19:51 CET 2009
75 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
76 together.
77 - add some examples on how to combine other event loops with Coro in
78 Coro::AnyEvent, and how to run it (and not to block). Seems to be
79 the most common source of confusion.
80 - try to catch people naively blocking in an event callback.
81 - work around the perl filehandle bug issue in conjunction with
82 older common::sense (as indirectly pointed out by ZSystem).
83 - clarify the "not from signal handlers" section.
84
855.2 Sun Oct 4 14:54:24 CEST 2009
86 - Coro::Storable destroyed the prototypes of the functions it wrapped.
87 - export rouse_cb and rouse_wait by default now.
88 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
89 - new method $state->swap_sv.
90 - added section on "windows process emulation" to the manpage,
91 after a not-so-fruitful (nor-friendly) "discussion" with chip
92 salzenberg (discussion implies arguments, but his only arguments
93 were ad-hominems, one wonders why he started it in the first
94 place). I hope this explains it well enough for him to understand,
95 and maybe well enough for others to understand.
96 - use common::sense everywhere now.
97 - idle callbacks are no longer supported, use idle coros instead.
98 - print a thread listing when a deadlock is detected.
99
1005.17 Sat Aug 22 23:09:31 CEST 2009
101 - work around a bug in the perl debugger causing crashes
102 when running under the debugger by marking _pool_handler as nodebug.
103 - speed up Coro::async considerably.
104 - try some hacks to get netbsd to work "more often" - their broken
105 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
106 - convert Coro to AE 5.0 API.
107
1085.162 Tue Jul 28 04:04:03 CEST 2009
109 - perl 5.8.2 is now minimum requirement.
110 - skip t/19_handle.t on broken windows perls.
111
1125.161 Wed Jul 22 04:47:38 CEST 2009
113 - Coro::AnyEvent::poll could have a different prototype when EV was
114 used as backend (analyzed by Tatsuhiko Miyagawa).
115 - Coro::AnyEvent errornously initialised the event loop when loaded,
116 not on demand.
117 - try to workaround rare */t/01_unblock.t failures.
118
1195.16 Tue Jul 21 01:44:37 CEST 2009
120 - Coro::AnyEvent failed to hook into the event loop
121 when no threads had been readied between detecting
122 the event loop and actually running it.
123 - considerably speed up Coro::Select by taking avdantage
124 of AnyEvent > 4.8 and some other optimisations.
125 - implement paragraph readline mode in Coro::Handle
126 (based on patches by Zsbán Ambrus).
127 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
128 and analyzed by Yasuhiro MATSUMOTO).
129 - clarified libcoro license and copyright.
130 - someone stole my EXTRA_META!!!
131 - implement Coro::Select::patch_pp_sselect and it's brother,
132 for hardcode select overriding.
133
1345.151 Mon Jul 6 05:41:57 CEST 2009
135 - backport to windows process emulation code again (patch by
136 Yasuhiro MATSUMOTO).
137 - slightly update Coro::MakeMaker.
138
1395.15 Tue Jun 30 10:28:06 CEST 2009
140 - deprecate Coro::Socket, document how to get ipv6 support via
141 AnyEvent::Socket instead.
142 - implement signal->wait ($cb) interface, similar to semaphores.
143 - work around SvOK not supporting getmagic, so we have to getmagic
144 to test for undef :/ (reported by Matthias Waldorf).
145 - load Coro::AnyEvent in all modules using AnyEvent.
146 - work around perl corrupting our internal data structures,
147 reported by Tokuhiro Matsuno.
148 - enable per-coroutine real and cpu time gathering
149 (Coro::State::enable_times).
150
1515.14 Wed Jun 24 01:37:48 CEST 2009
152 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
153 as this seems to have been a difficult concept (poll, sleep, idle,
154 idle_upto).
155 - add Coro::AnyEvent::readable/writable functions.
156 - clarify Coro::EV/Event/AnyEvent manpages.
157 - free per-thread global scalars in the thread calling ->cancel, to
158 avoid crashes when $_, $@ etc., are magical but some of those
159 had already been freed.
160 - "unexperimentalise" the callback interface for Coro::Semaphore.
161 - speed up ready queue management/context switching by using a linked
162 list instead of an array (~5-10%).
163 - implement "watch" command in Coro::Debug shells.
164 - for fun, implement time-slicing as an example in the manpage.
165 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
166 Coro::Event, use the normal AnyEvent handling instead of dieing
167 (the same is true for Coro::Handle).
168 - properly document Coro::EV::timed_io_once.
169 - avoid unneccessary ->cancel calls in Coro::Handle.
170 - maybe make it work on mingw32 with win32 backend
171 (based on patch by Yasuhiro Matsumoto).
172
1735.132 Fri May 29 09:00:39 CEST 2009
174 - do not keep a reference to the argument itself in
175 Coro::Semaphore::guard, as it could change later.
176 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
177 should support a prepare callback.
178
1795.131 Mon Mar 16 23:20:37 CET 2009
9 - implement and document Coro->suspend, Coro->resume. 180 - implement and document Coro->suspend, Coro->resume.
181 - fix Coro::Select implementation to not (often) close
182 the passed file descriptors (testcase provided by pippijn).
10 183
115.13 Mon Dec 15 21:51:42 CET 2008 1845.13 Mon Dec 15 21:51:42 CET 2008
12 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave). 185 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
13 - don't set diehook to C<undef> but instead to NULL, to avoid 186 - don't set diehook to C<undef> but instead to NULL, to avoid
14 spurious warnings. 187 spurious warnings.
