10 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 13 - speed up Coro::async considerably.

125.0 155.162 Tue Jul 28 04:04:03 CEST 2009
16 - perl 5.8.2 is now minimum requirement.
17 - skip t/19_handle.t on broken windows perls.
18
195.161 Wed Jul 22 04:47:38 CEST 2009
20 - Coro::AnyEvent::poll could have a different prototype when EV was
21 used as backend (analyzed by Tatsuhiko Miyagawa).
22 - Coro::AnyEvent errornously initialised the event loop when loaded,
23 not on demand.
24 - try to workaround rare */t/01_unblock.t failures.
25
265.16 Tue Jul 21 01:44:37 CEST 2009
27 - Coro::AnyEvent failed to hook into the event loop
28 when no threads had been readied between detecting
29 the event loop and actually running it.
30 - considerably speed up Coro::Select by taking avdantage
31 of AnyEvent > 4.8 and some other optimisations.
32 - implement paragraph readline mode in Coro::Handle
33 (based on patches by Zsbán Ambrus).
34 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
35 and analyzed by Yasuhiro MATSUMOTO).
36 - clarified libcoro license and copyright.
37 - someone stole my EXTRA_META!!!
38 - implement Coro::Select::patch_pp_sselect and it's brother,
39 for hardcode select overriding.
40
415.151 Mon Jul 6 05:41:57 CEST 2009
42 - backport to windows process emulation code again (patch by
43 Yasuhiro MATSUMOTO).
44 - slightly update Coro::MakeMaker.
45
465.15 Tue Jun 30 10:28:06 CEST 2009
47 - deprecate Coro::Socket, document how to get ipv6 support via
48 AnyEvent::Socket instead.
49 - implement signal->wait ($cb) interface, similar to semaphores.
50 - work around SvOK not supporting getmagic, so we have to getmagic
51 to test for undef :/ (reported by Matthias Waldorf).
52 - load Coro::AnyEvent in all modules using AnyEvent.
53 - work around perl corrupting our internal data structures,
54 reported by Tokuhiro Matsuno.
55 - enable per-coroutine real and cpu time gathering
56 (Coro::State::enable_times).
57
585.14 Wed Jun 24 01:37:48 CEST 2009
59 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
60 as this seems to have been a difficult concept (poll, sleep, idle,
61 idle_upto).
62 - add Coro::AnyEvent::readable/writable functions.
63 - clarify Coro::EV/Event/AnyEvent manpages.
64 - free per-thread global scalars in the thread calling ->cancel, to
65 avoid crashes when $_, $@ etc., are magical but some of those
66 had already been freed.
67 - "unexperimentalise" the callback interface for Coro::Semaphore.
68 - speed up ready queue management/context switching by using a linked
69 list instead of an array (~5-10%).
70 - implement "watch" command in Coro::Debug shells.
71 - for fun, implement time-slicing as an example in the manpage.
72 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
73 Coro::Event, use the normal AnyEvent handling instead of dieing
74 (the same is true for Coro::Handle).
75 - properly document Coro::EV::timed_io_once.
76 - avoid unneccessary ->cancel calls in Coro::Handle.
77 - maybe make it work on mingw32 with win32 backend
78 (based on patch by Yasuhiro Matsumoto).
79
805.132 Fri May 29 09:00:39 CEST 2009
81 - do not keep a reference to the argument itself in
82 Coro::Semaphore::guard, as it could change later.
83 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
84 should support a prepare callback.
85
865.131 Mon Mar 16 23:20:37 CET 2009
87 - implement and document Coro->suspend, Coro->resume.
88 - fix Coro::Select implementation to not (often) close
89 the passed file descriptors (testcase provided by pippijn).
90
915.13 Mon Dec 15 21:51:42 CET 2008
92 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
93 - don't set diehook to C<undef> but instead to NULL, to avoid
94 spurious warnings.
95 - fix a lot of bugs in Coro::SemaphoreSet.
96 - Coro::SemaphoreSet will less often create a semaphore needlessly.
97 - add Coro::SemaphoreSet::count and wait methods.
98 - take advantage of the new Guard module.
99 - deprecate Coro::guard.
100 - try to fix the dreaded 01_unblock tests once more. I hate it when
101 testsuites need more fixing than the code they are supposed to test.
102 - croak in more cases when a required callback isn't resolvable.
103 - fix some minor issues in Coro::State->call/eval.
104 - use current coroutine context instead of a temporary one
105 when temporarily switching to another coroutine.
106 - do not call C-level on_destroy handlers during global destruction,
107 to avoid needless segfaults.
108
1095.12 Sun Dec 7 13:30:38 CET 2008
110 - add default config for MirOS, which seems to be a bug-to-bug
111 compatible fork of openbsd ("world domination by releasing
112 openbsd cvs before the openbsd folks do it" or so :).
113 - free_padlist did destroy the names pad, not good, but didn't
114 seem to bother perl - this could fix issues such as eval ""
115 inside a function called from multiple coroutines.
116 - use a different method to detect destruction time.
117 - be more careful when freeing padlists just before global
118 destruction.
119 - fixed and expanded the call/cc example.
120 - renamed _terminate to _coro_run.
121 - new method Coro::Channel->shutdown.
122 - try pthreads on openbsd <4.4 (broken sigaltstack, will
123 pthreads fare better?).
124 - be less picky about destroying "a" running coroutine.
125
1265.11 Tue Nov 25 21:49:05 CET 2008
127 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
128 working code with failed assertions, introducing more bugs than
129 it fixes, requiring elaborate workarounds :(
130
1315.1 Mon Nov 24 08:54:59 CET 2008
132 - wrote a small introductory tutorial - Coro::Intro.
133 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
134 - Coro::Select did errornously dup the file descriptors
135 and didn't work with all AnyEvent backends.
136 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
137 LWP data transfers.
138 - disassociate c contexts from coro objects - this is agruably more
139 correct, but mostly allows sharing of cctxs between coro and state
140 objects, for added memory savings and speed increases.
141 - bumped $Coro::POOL_RSS up to 32kb by default.
142 - no longer set the optype to OP_CUSTOM, as B::* understandably
143 doesn't like this very much (and we *are* a type of entersub).
144 - implement state cloning, just to prove that call/cc can be done.
145 - automatically load Coro::AnyEvent in Coro::Handle.
146 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
147 do not have this method (and don't need it either).
148 - speed up generic anyevent methods in Coro::Handle by using rouse
149 callbacks.
150 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
151 others. It also makes the debugger happier, as you can trace
152 through the idle threads now.
153 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
154 - eg/event was pretty broken.
155 - better 5.8.6 compatibility.

176 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
177 conversion of callback-style to blocking-style.
178 - new methods $coro->schedule_to and ->cede_to, to specifically
179 schedule or cede to a specific coroutine.

56 making signals reliable for the first time. 205 making signals reliable for the first time.
206 - used new SLF interface and other optimisations to speed up async_pool
207 by a factor of two. It also doesn't rely on perl's exception mechanism
208 to exit anymore. The overhead for terminating an async_pool, coro over
209 a normal async is now very small.
210 - sped up coroutine creation/destruction by 40%.

214 - use new rouse functions to speed up and simplify Coro::BDB.
215 - make "prefer perl native functions" work with threaded perls.
216 - condense Coro::Debug ps output, hint at v and w flags.
217 - (libcoro) lots of minor cleanups and portability improvements.
