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
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 - slightly updated Coro::Intro for recent changes.
15
165.25 Thu Nov 11 01:08:39 CET 2010
17 - try a different approach on netbsd - netbsd 5 finally has marginally
18 working pthreads, but still broken ucontext/sigaltstack.
19 - openbsd 4.8 finally got their act together, Coro works out of the box
20 with asm, setjmp and pthreads (no change, just informational).
21
225.24 Sat Oct 23 11:27:12 CEST 2010
23 - port to the EV 4.0 API.
24 - work around bugs in mingw32, making strawberry perl work
25 out of the box.
26 - correctly modify Coro::AIO function prototypes
27 so that they reflect the "no optional parameters" rule.
28 - "ported" libcoro to C++.
29
305.23 Mon May 17 18:50:42 CEST 2010
31 - be more resistant to ordering changes when initialising
32 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
33 Waldorf).
34 - document that perl 5.12 deliberately removed support for cloning.
35
365.22 Wed Apr 14 03:55:35 CEST 2010
37 - correctly return udnef on errors in Coro::Handle::read/write
38 (testcase by Marc Mims).
39 - convert Coro::Util into a "perl compatibility wrapper" - the functions
40 are less useful now, but are drop-in replacements for existing
41 functions, listing better alternatives in the documentation. This also
42 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
43 with Coro::Util::inet_aton.
44 - do not override $Coro::idle unconditionally in Coro.pm, as other
45 modules could have provided their own idle coro already
46 (for exmaple, Coro::AnyEvent).
47 - fix Coro::Util::gethost* functions.
48 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
49
505.21 Wed Dec 16 07:19:51 CET 2009
51 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
52 together.
53 - add some examples on how to combine other event loops with Coro in
54 Coro::AnyEvent, and how to run it (and not to block). Seems to be
55 the most common source of confusion.
56 - try to catch people naively blocking in an event callback.
57 - work around the perl filehandle bug issue in conjunction with
58 older common::sense (as indirectly pointed out by ZSystem).
59 - clarify the "not from signal handlers" section.
60
615.2 Sun Oct 4 14:54:24 CEST 2009
62 - Coro::Storable destroyed the prototypes of the functions it wrapped.
63 - export rouse_cb and rouse_wait by default now.
64 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
65 - new method $state->swap_sv.
66 - added section on "windows process emulation" to the manpage,
67 after a not-so-fruitful (nor-friendly) "discussion" with chip
68 salzenberg (discussion implies arguments, but his only arguments
69 were ad-hominems, one wonders why he started it in the first
70 place). I hope this explains it well enough for him to understand,
71 and maybe well enough for others to understand.
72 - use common::sense everywhere now.
73 - idle callbacks are no longer supported, use idle coros instead.
74 - print a thread listing when a deadlock is detected.
75
765.17 Sat Aug 22 23:09:31 CEST 2009
77 - work around a bug in the perl debugger causing crashes
78 when running under the debugger by marking _pool_handler as nodebug.
79 - speed up Coro::async considerably.
80 - try some hacks to get netbsd to work "more often" - their broken
81 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
82 - convert Coro to AE 5.0 API.
83
845.162 Tue Jul 28 04:04:03 CEST 2009
85 - perl 5.8.2 is now minimum requirement.
86 - skip t/19_handle.t on broken windows perls.
87
885.161 Wed Jul 22 04:47:38 CEST 2009
89 - Coro::AnyEvent::poll could have a different prototype when EV was
90 used as backend (analyzed by Tatsuhiko Miyagawa).
91 - Coro::AnyEvent errornously initialised the event loop when loaded,
92 not on demand.
93 - try to workaround rare */t/01_unblock.t failures.
94
955.16 Tue Jul 21 01:44:37 CEST 2009
96 - Coro::AnyEvent failed to hook into the event loop
97 when no threads had been readied between detecting
98 the event loop and actually running it.
99 - considerably speed up Coro::Select by taking avdantage
100 of AnyEvent > 4.8 and some other optimisations.
101 - implement paragraph readline mode in Coro::Handle
102 (based on patches by Zsbán Ambrus).
103 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
104 and analyzed by Yasuhiro MATSUMOTO).
105 - clarified libcoro license and copyright.
106 - someone stole my EXTRA_META!!!
107 - implement Coro::Select::patch_pp_sselect and it's brother,
108 for hardcode select overriding.
109
1105.151 Mon Jul 6 05:41:57 CEST 2009
111 - backport to windows process emulation code again (patch by
112 Yasuhiro MATSUMOTO).
113 - slightly update Coro::MakeMaker.
114
1155.15 Tue Jun 30 10:28:06 CEST 2009
116 - deprecate Coro::Socket, document how to get ipv6 support via
117 AnyEvent::Socket instead.
118 - implement signal->wait ($cb) interface, similar to semaphores.
119 - work around SvOK not supporting getmagic, so we have to getmagic
120 to test for undef :/ (reported by Matthias Waldorf).
121 - load Coro::AnyEvent in all modules using AnyEvent.
122 - work around perl corrupting our internal data structures,
123 reported by Tokuhiro Matsuno.
124 - enable per-coroutine real and cpu time gathering
125 (Coro::State::enable_times).
126
1275.14 Wed Jun 24 01:37:48 CEST 2009
128 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
129 as this seems to have been a difficult concept (poll, sleep, idle,
130 idle_upto).
131 - add Coro::AnyEvent::readable/writable functions.
132 - clarify Coro::EV/Event/AnyEvent manpages.
133 - free per-thread global scalars in the thread calling ->cancel, to
134 avoid crashes when $_, $@ etc., are magical but some of those
135 had already been freed.
136 - "unexperimentalise" the callback interface for Coro::Semaphore.
137 - speed up ready queue management/context switching by using a linked
138 list instead of an array (~5-10%).
139 - implement "watch" command in Coro::Debug shells.
140 - for fun, implement time-slicing as an example in the manpage.
141 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
142 Coro::Event, use the normal AnyEvent handling instead of dieing
143 (the same is true for Coro::Handle).
144 - properly document Coro::EV::timed_io_once.
145 - avoid unneccessary ->cancel calls in Coro::Handle.
146 - maybe make it work on mingw32 with win32 backend
147 (based on patch by Yasuhiro Matsumoto).
148
1495.132 Fri May 29 09:00:39 CEST 2009
150 - do not keep a reference to the argument itself in
151 Coro::Semaphore::guard, as it could change later.
152 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
153 should support a prepare callback.
154
1555.131 Mon Mar 16 23:20:37 CET 2009
156 - implement and document Coro->suspend, Coro->resume.
157 - fix Coro::Select implementation to not (often) close
158 the passed file descriptors (testcase provided by pippijn).
159
1605.13 Mon Dec 15 21:51:42 CET 2008
161 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
162 - don't set diehook to C<undef> but instead to NULL, to avoid
163 spurious warnings.
164 - fix a lot of bugs in Coro::SemaphoreSet.
165 - Coro::SemaphoreSet will less often create a semaphore needlessly.
166 - add Coro::SemaphoreSet::count and wait methods.
167 - take advantage of the new Guard module.
168 - deprecate Coro::guard.
169 - try to fix the dreaded 01_unblock tests once more. I hate it when
170 testsuites need more fixing than the code they are supposed to test.
171 - croak in more cases when a required callback isn't resolvable.
172 - fix some minor issues in Coro::State->call/eval.
173 - use current coroutine context instead of a temporary one
174 when temporarily switching to another coroutine.
175 - do not call C-level on_destroy handlers during global destruction,
176 to avoid needless segfaults.
177
1785.12 Sun Dec 7 13:30:38 CET 2008
179 - add default config for MirOS, which seems to be a bug-to-bug
180 compatible fork of openbsd ("world domination by releasing
181 openbsd cvs before the openbsd folks do it" or so :).
182 - free_padlist did destroy the names pad, not good, but didn't
183 seem to bother perl - this could fix issues such as eval ""
184 inside a function called from multiple coroutines.
185 - use a different method to detect destruction time.
186 - be more careful when freeing padlists just before global
187 destruction.
188 - fixed and expanded the call/cc example.
189 - renamed _terminate to _coro_run.
190 - new method Coro::Channel->shutdown.
191 - try pthreads on openbsd <4.4 (broken sigaltstack, will
192 pthreads fare better?).
193 - be less picky about destroying "a" running coroutine.
194
1955.11 Tue Nov 25 21:49:05 CET 2008
196 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
197 working code with failed assertions, introducing more bugs than
198 it fixes, requiring elaborate workarounds :(
199
2005.1 Mon Nov 24 08:54:59 CET 2008
201 - wrote a small introductory tutorial - Coro::Intro.
8 - convert Coro::Timer and Coro::Select to rouse API. 202 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
9 - Coro::Select did errornously dup the file descriptors 203 - Coro::Select did errornously dup the file descriptors
10 and didn't work with all AnyEvent backends. 204 and didn't work with all AnyEvent backends.
205 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
206 LWP data transfers.
207 - disassociate c contexts from coro objects - this is agruably more
208 correct, but mostly allows sharing of cctxs between coro and state
209 objects, for added memory savings and speed increases.
210 - bumped $Coro::POOL_RSS up to 32kb by default.
211 - no longer set the optype to OP_CUSTOM, as B::* understandably
212 doesn't like this very much (and we *are* a type of entersub).
213 - implement state cloning, just to prove that call/cc can be done.
214 - automatically load Coro::AnyEvent in Coro::Handle.
215 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
216 do not have this method (and don't need it either).
217 - speed up generic anyevent methods in Coro::Handle by using rouse
218 callbacks.
219 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
220 others. It also makes the debugger happier, as you can trace
221 through the idle threads now.
222 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
223 - eg/event was pretty broken.
224 - better 5.8.6 compatibility.

13 - NEW ARCHITECTURE: use the latest 4.x version if you experience 227 - NEW ARCHITECTURE: use the latest 4.x version if you experience
14 stability issues. 228 stability issues.
15 - bump API version to 7 - all dependents must be recompiled. 229 - bump API version to 7 - all dependents must be recompiled.
