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)?

8 TODO: Coro/Intro 9 - correctly modify Coro::AIO function prototypes
10 so that they reflect the "no optional parameters" rule.
11 - "ported" libcoro to C++.
12
135.23 Mon May 17 18:50:42 CEST 2010
14 - be more resistant to ordering changes when initialising
15 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
16 Waldorf).
17 - document that perl 5.12 deliberately removed support for cloning.
18
195.22 Wed Apr 14 03:55:35 CEST 2010
20 - correctly return udnef on errors in Coro::Handle::read/write
21 (testcase by Marc Mims).
22 - convert Coro::Util into a "perl compatibility wrapper" - the functions
23 are less useful now, but are drop-in replacements for existing
24 functions, listing better alternatives in the documentation. This also
25 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
26 with Coro::Util::inet_aton.
27 - do not override $Coro::idle unconditionally in Coro.pm, as other
28 modules could have provided their own idle coro already
29 (for exmaple, Coro::AnyEvent).
30 - fix Coro::Util::gethost* functions.
31 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
32
335.21 Wed Dec 16 07:19:51 CET 2009
34 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
35 together.
36 - add some examples on how to combine other event loops with Coro in
37 Coro::AnyEvent, and how to run it (and not to block). Seems to be
38 the most common source of confusion.
39 - try to catch people naively blocking in an event callback.
40 - work around the perl filehandle bug issue in conjunction with
41 older common::sense (as indirectly pointed out by ZSystem).
42 - clarify the "not from signal handlers" section.
43
445.2 Sun Oct 4 14:54:24 CEST 2009
45 - Coro::Storable destroyed the prototypes of the functions it wrapped.
46 - export rouse_cb and rouse_wait by default now.
47 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
48 - new method $state->swap_sv.
49 - added section on "windows process emulation" to the manpage,
50 after a not-so-fruitful (nor-friendly) "discussion" with chip
51 salzenberg (discussion implies arguments, but his only arguments
52 were ad-hominems, one wonders why he started it in the first
53 place). I hope this explains it well enough for him to understand,
54 and maybe well enough for others to understand.
55 - use common::sense everywhere now.
56 - idle callbacks are no longer supported, use idle coros instead.
57 - print a thread listing when a deadlock is detected.
58
595.17 Sat Aug 22 23:09:31 CEST 2009
60 - work around a bug in the perl debugger causing crashes
61 when running under the debugger by marking _pool_handler as nodebug.
62 - speed up Coro::async considerably.
63 - try some hacks to get netbsd to work "more often" - their broken
64 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
65 - convert Coro to AE 5.0 API.
66
675.162 Tue Jul 28 04:04:03 CEST 2009
68 - perl 5.8.2 is now minimum requirement.
69 - skip t/19_handle.t on broken windows perls.
70
715.161 Wed Jul 22 04:47:38 CEST 2009
72 - Coro::AnyEvent::poll could have a different prototype when EV was
73 used as backend (analyzed by Tatsuhiko Miyagawa).
74 - Coro::AnyEvent errornously initialised the event loop when loaded,
75 not on demand.
76 - try to workaround rare */t/01_unblock.t failures.
77
785.16 Tue Jul 21 01:44:37 CEST 2009
79 - Coro::AnyEvent failed to hook into the event loop
80 when no threads had been readied between detecting
81 the event loop and actually running it.
82 - considerably speed up Coro::Select by taking avdantage
83 of AnyEvent > 4.8 and some other optimisations.
84 - implement paragraph readline mode in Coro::Handle
85 (based on patches by Zsbán Ambrus).
86 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
87 and analyzed by Yasuhiro MATSUMOTO).
88 - clarified libcoro license and copyright.
89 - someone stole my EXTRA_META!!!
90 - implement Coro::Select::patch_pp_sselect and it's brother,
91 for hardcode select overriding.
92
935.151 Mon Jul 6 05:41:57 CEST 2009
94 - backport to windows process emulation code again (patch by
95 Yasuhiro MATSUMOTO).
96 - slightly update Coro::MakeMaker.
97
985.15 Tue Jun 30 10:28:06 CEST 2009
99 - deprecate Coro::Socket, document how to get ipv6 support via
100 AnyEvent::Socket instead.
101 - implement signal->wait ($cb) interface, similar to semaphores.
102 - work around SvOK not supporting getmagic, so we have to getmagic
103 to test for undef :/ (reported by Matthias Waldorf).
104 - load Coro::AnyEvent in all modules using AnyEvent.
105 - work around perl corrupting our internal data structures,
106 reported by Tokuhiro Matsuno.
107 - enable per-coroutine real and cpu time gathering
108 (Coro::State::enable_times).
109
1105.14 Wed Jun 24 01:37:48 CEST 2009
111 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
112 as this seems to have been a difficult concept (poll, sleep, idle,
113 idle_upto).
114 - add Coro::AnyEvent::readable/writable functions.
115 - clarify Coro::EV/Event/AnyEvent manpages.
116 - free per-thread global scalars in the thread calling ->cancel, to
117 avoid crashes when $_, $@ etc., are magical but some of those
118 had already been freed.
119 - "unexperimentalise" the callback interface for Coro::Semaphore.
120 - speed up ready queue management/context switching by using a linked
121 list instead of an array (~5-10%).
122 - implement "watch" command in Coro::Debug shells.
123 - for fun, implement time-slicing as an example in the manpage.
124 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
125 Coro::Event, use the normal AnyEvent handling instead of dieing
126 (the same is true for Coro::Handle).
127 - properly document Coro::EV::timed_io_once.
128 - avoid unneccessary ->cancel calls in Coro::Handle.
129 - maybe make it work on mingw32 with win32 backend
130 (based on patch by Yasuhiro Matsumoto).
131
1325.132 Fri May 29 09:00:39 CEST 2009
133 - do not keep a reference to the argument itself in
134 Coro::Semaphore::guard, as it could change later.
135 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
136 should support a prepare callback.
137
1385.131 Mon Mar 16 23:20:37 CET 2009
139 - implement and document Coro->suspend, Coro->resume.
140 - fix Coro::Select implementation to not (often) close
141 the passed file descriptors (testcase provided by pippijn).
142
1435.13 Mon Dec 15 21:51:42 CET 2008
144 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
145 - don't set diehook to C<undef> but instead to NULL, to avoid
146 spurious warnings.
147 - fix a lot of bugs in Coro::SemaphoreSet.
148 - Coro::SemaphoreSet will less often create a semaphore needlessly.
149 - add Coro::SemaphoreSet::count and wait methods.
150 - take advantage of the new Guard module.
151 - deprecate Coro::guard.
152 - try to fix the dreaded 01_unblock tests once more. I hate it when
153 testsuites need more fixing than the code they are supposed to test.
154 - croak in more cases when a required callback isn't resolvable.
155 - fix some minor issues in Coro::State->call/eval.
156 - use current coroutine context instead of a temporary one
157 when temporarily switching to another coroutine.
158 - do not call C-level on_destroy handlers during global destruction,
159 to avoid needless segfaults.
160
1615.12 Sun Dec 7 13:30:38 CET 2008
162 - add default config for MirOS, which seems to be a bug-to-bug
163 compatible fork of openbsd ("world domination by releasing
164 openbsd cvs before the openbsd folks do it" or so :).
165 - free_padlist did destroy the names pad, not good, but didn't
166 seem to bother perl - this could fix issues such as eval ""
167 inside a function called from multiple coroutines.
168 - use a different method to detect destruction time.
169 - be more careful when freeing padlists just before global
170 destruction.
171 - fixed and expanded the call/cc example.
172 - renamed _terminate to _coro_run.
173 - new method Coro::Channel->shutdown.
174 - try pthreads on openbsd <4.4 (broken sigaltstack, will
175 pthreads fare better?).
176 - be less picky about destroying "a" running coroutine.
177
1785.11 Tue Nov 25 21:49:05 CET 2008
179 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
180 working code with failed assertions, introducing more bugs than
181 it fixes, requiring elaborate workarounds :(
182

12 and didn't work with all AnyEvent backends. 187 and didn't work with all AnyEvent backends.
188 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
189 LWP data transfers.
13 - disassociate c contexts from coro objects - this is agruably more 190 - disassociate c contexts from coro objects - this is agruably more
14 correct, but mostly allows sharing of cctxs between coro and state 191 correct, but mostly allows sharing of cctxs between coro and state
15 objects, for added memory savings and speed increases. 192 objects, for added memory savings and speed increases.
16 - bumped $Coro::POOL_RSS up to 32kb by default. 193 - bumped $Coro::POOL_RSS up to 32kb by default.
17 - no longer set the optype to OP_CUSTOM, as B::* understandably 194 - no longer set the optype to OP_CUSTOM, as B::* understandably

23 - speed up generic anyevent methods in Coro::Handle by using rouse 200 - speed up generic anyevent methods in Coro::Handle by using rouse
24 callbacks. 201 callbacks.
25 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and 202 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
26 others. It also makes the debugger happier, as you can trace 203 others. It also makes the debugger happier, as you can trace
27 through the idle threads now. 204 through the idle threads now.
205 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
