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: unready_all
5 actor model (which is cool in a lot of important aspects (failures!), 5TODO: myhttpd header parsing
6 but very lacking in others (higher level ipc)). 6TODO: channel->maxsize(newsize)?

7 8
8 TODO: Coro/Intro 9 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
10 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
11 method call.
12 - undocument Coro::Timer::sleep and obsolete whole module.
13 - optimise Coro::Timer::timeout memory and cpu usage.
14
155.25 Thu Nov 11 01:08:39 CET 2010
16 - try a different approach on netbsd - netbsd 5 finally has marginally
17 working pthreads, but still broken ucontext/sigaltstack.
18 - openbsd 4.8 finally got their act together, Coro works out of the box
19 with asm, setjmp and pthreads (no change, just informational).
20
215.24 Sat Oct 23 11:27:12 CEST 2010
22 - port to the EV 4.0 API.
23 - work around bugs in mingw32, making strawberry perl work
24 out of the box.
25 - correctly modify Coro::AIO function prototypes
26 so that they reflect the "no optional parameters" rule.
27 - "ported" libcoro to C++.
28
295.23 Mon May 17 18:50:42 CEST 2010
30 - be more resistant to ordering changes when initialising
31 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
32 Waldorf).
33 - document that perl 5.12 deliberately removed support for cloning.
34
355.22 Wed Apr 14 03:55:35 CEST 2010
36 - correctly return udnef on errors in Coro::Handle::read/write
37 (testcase by Marc Mims).
38 - convert Coro::Util into a "perl compatibility wrapper" - the functions
39 are less useful now, but are drop-in replacements for existing
40 functions, listing better alternatives in the documentation. This also
41 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
42 with Coro::Util::inet_aton.
43 - do not override $Coro::idle unconditionally in Coro.pm, as other
44 modules could have provided their own idle coro already
45 (for exmaple, Coro::AnyEvent).
46 - fix Coro::Util::gethost* functions.
47 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
48
495.21 Wed Dec 16 07:19:51 CET 2009
50 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
51 together.
52 - add some examples on how to combine other event loops with Coro in
53 Coro::AnyEvent, and how to run it (and not to block). Seems to be
54 the most common source of confusion.
55 - try to catch people naively blocking in an event callback.
56 - work around the perl filehandle bug issue in conjunction with
57 older common::sense (as indirectly pointed out by ZSystem).
58 - clarify the "not from signal handlers" section.
59
605.2 Sun Oct 4 14:54:24 CEST 2009
61 - Coro::Storable destroyed the prototypes of the functions it wrapped.
62 - export rouse_cb and rouse_wait by default now.
63 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
64 - new method $state->swap_sv.
65 - added section on "windows process emulation" to the manpage,
66 after a not-so-fruitful (nor-friendly) "discussion" with chip
67 salzenberg (discussion implies arguments, but his only arguments
68 were ad-hominems, one wonders why he started it in the first
69 place). I hope this explains it well enough for him to understand,
70 and maybe well enough for others to understand.
71 - use common::sense everywhere now.
72 - idle callbacks are no longer supported, use idle coros instead.
73 - print a thread listing when a deadlock is detected.
74
755.17 Sat Aug 22 23:09:31 CEST 2009
76 - work around a bug in the perl debugger causing crashes
77 when running under the debugger by marking _pool_handler as nodebug.
78 - speed up Coro::async considerably.
79 - try some hacks to get netbsd to work "more often" - their broken
80 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
81 - convert Coro to AE 5.0 API.
82
835.162 Tue Jul 28 04:04:03 CEST 2009
84 - perl 5.8.2 is now minimum requirement.
85 - skip t/19_handle.t on broken windows perls.
86
875.161 Wed Jul 22 04:47:38 CEST 2009
88 - Coro::AnyEvent::poll could have a different prototype when EV was
89 used as backend (analyzed by Tatsuhiko Miyagawa).
90 - Coro::AnyEvent errornously initialised the event loop when loaded,
91 not on demand.
92 - try to workaround rare */t/01_unblock.t failures.
93
945.16 Tue Jul 21 01:44:37 CEST 2009
95 - Coro::AnyEvent failed to hook into the event loop
96 when no threads had been readied between detecting
97 the event loop and actually running it.
98 - considerably speed up Coro::Select by taking avdantage
99 of AnyEvent > 4.8 and some other optimisations.
100 - implement paragraph readline mode in Coro::Handle
101 (based on patches by Zsbán Ambrus).
102 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
103 and analyzed by Yasuhiro MATSUMOTO).
104 - clarified libcoro license and copyright.
105 - someone stole my EXTRA_META!!!
106 - implement Coro::Select::patch_pp_sselect and it's brother,
107 for hardcode select overriding.
108
1095.151 Mon Jul 6 05:41:57 CEST 2009
110 - backport to windows process emulation code again (patch by
111 Yasuhiro MATSUMOTO).
112 - slightly update Coro::MakeMaker.
113
1145.15 Tue Jun 30 10:28:06 CEST 2009
115 - deprecate Coro::Socket, document how to get ipv6 support via
116 AnyEvent::Socket instead.
117 - implement signal->wait ($cb) interface, similar to semaphores.
118 - work around SvOK not supporting getmagic, so we have to getmagic
119 to test for undef :/ (reported by Matthias Waldorf).
120 - load Coro::AnyEvent in all modules using AnyEvent.
121 - work around perl corrupting our internal data structures,
122 reported by Tokuhiro Matsuno.
123 - enable per-coroutine real and cpu time gathering
124 (Coro::State::enable_times).
125
1265.14 Wed Jun 24 01:37:48 CEST 2009
127 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
128 as this seems to have been a difficult concept (poll, sleep, idle,
129 idle_upto).
130 - add Coro::AnyEvent::readable/writable functions.
131 - clarify Coro::EV/Event/AnyEvent manpages.
132 - free per-thread global scalars in the thread calling ->cancel, to
133 avoid crashes when $_, $@ etc., are magical but some of those
134 had already been freed.
135 - "unexperimentalise" the callback interface for Coro::Semaphore.
136 - speed up ready queue management/context switching by using a linked
137 list instead of an array (~5-10%).
138 - implement "watch" command in Coro::Debug shells.
139 - for fun, implement time-slicing as an example in the manpage.
140 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
141 Coro::Event, use the normal AnyEvent handling instead of dieing
142 (the same is true for Coro::Handle).
143 - properly document Coro::EV::timed_io_once.
144 - avoid unneccessary ->cancel calls in Coro::Handle.
145 - maybe make it work on mingw32 with win32 backend
146 (based on patch by Yasuhiro Matsumoto).
147
1485.132 Fri May 29 09:00:39 CEST 2009
149 - do not keep a reference to the argument itself in
150 Coro::Semaphore::guard, as it could change later.
151 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
152 should support a prepare callback.
153
1545.131 Mon Mar 16 23:20:37 CET 2009
155 - implement and document Coro->suspend, Coro->resume.
156 - fix Coro::Select implementation to not (often) close
157 the passed file descriptors (testcase provided by pippijn).
158
1595.13 Mon Dec 15 21:51:42 CET 2008
160 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
161 - don't set diehook to C<undef> but instead to NULL, to avoid
162 spurious warnings.
163 - fix a lot of bugs in Coro::SemaphoreSet.
164 - Coro::SemaphoreSet will less often create a semaphore needlessly.
165 - add Coro::SemaphoreSet::count and wait methods.
166 - take advantage of the new Guard module.
167 - deprecate Coro::guard.
168 - try to fix the dreaded 01_unblock tests once more. I hate it when
169 testsuites need more fixing than the code they are supposed to test.
170 - croak in more cases when a required callback isn't resolvable.
171 - fix some minor issues in Coro::State->call/eval.
172 - use current coroutine context instead of a temporary one
173 when temporarily switching to another coroutine.
174 - do not call C-level on_destroy handlers during global destruction,
175 to avoid needless segfaults.
176
1775.12 Sun Dec 7 13:30:38 CET 2008
178 - add default config for MirOS, which seems to be a bug-to-bug
179 compatible fork of openbsd ("world domination by releasing
180 openbsd cvs before the openbsd folks do it" or so :).
181 - free_padlist did destroy the names pad, not good, but didn't
182 seem to bother perl - this could fix issues such as eval ""
183 inside a function called from multiple coroutines.
184 - use a different method to detect destruction time.
185 - be more careful when freeing padlists just before global
186 destruction.
187 - fixed and expanded the call/cc example.
188 - renamed _terminate to _coro_run.
189 - new method Coro::Channel->shutdown.
190 - try pthreads on openbsd <4.4 (broken sigaltstack, will
191 pthreads fare better?).
192 - be less picky about destroying "a" running coroutine.
193
1945.11 Tue Nov 25 21:49:05 CET 2008
195 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
196 working code with failed assertions, introducing more bugs than
197 it fixes, requiring elaborate workarounds :(
198

12 and didn't work with all AnyEvent backends. 203 and didn't work with all AnyEvent backends.
204 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
205 LWP data transfers.
13 - disassociate c contexts from coro objects - this is agruably more 206 - disassociate c contexts from coro objects - this is agruably more
14 correct, but mostly allows sharing of cctxs between coro and state 207 correct, but mostly allows sharing of cctxs between coro and state
15 objects, for added memory savings and speed increases. 208 objects, for added memory savings and speed increases.
16 - bumped $Coro::POOL_RSS up to 32kb by default. 209 - bumped $Coro::POOL_RSS up to 32kb by default.

23 - speed up generic anyevent methods in Coro::Handle by using rouse 216 - speed up generic anyevent methods in Coro::Handle by using rouse
24 callbacks. 217 callbacks.
25 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and 218 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
26 others. It also makes the debugger happier, as you can trace 219 others. It also makes the debugger happier, as you can trace
27 through the idle threads now. 220 through the idle threads now.
221 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
28 - eg/event was pretty broken. 222 - eg/event was pretty broken.
