85.0 11TODO: times per-coroutine
12 - deprecate Coro::Socket, document how to get ipv6 support via
13 AnyEvent::Socket instead.
14 - implement signal->wait ($cb) interface, similar to semaphores.
15 - work around SvOK not supporting getmagic, so we have to getmagic
16 to test for undef :/ (reported by Matthias Waldorf).
17 - load Coro::AnyEvent in all modules using AnyEvent.
18 - work around perl corrupting our internal data structures,
19 reported by Tokuhiro Matsuno.

215.14 Wed Jun 24 01:37:48 CEST 2009
22 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
23 as this seems to have been a difficult concept (poll, sleep, idle,
24 idle_upto).
25 - add Coro::AnyEvent::readable/writable functions.
26 - clarify Coro::EV/Event/AnyEvent manpages.
27 - free per-thread global scalars in the thread calling ->cancel, to
28 avoid crashes when $_, $@ etc., are magical but some of those
29 had already been freed.
30 - "unexperimentalise" the callback interface for Coro::Semaphore.
31 - speed up ready queue management/context switching by using a linked
32 list instead of an array (~5-10%).
33 - implement "watch" command in Coro::Debug shells.
34 - for fun, implement time-slicing as an example in the manpage.
35 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
36 Coro::Event, use the normal AnyEvent handling instead of dieing
37 (the same is true for Coro::Handle).
38 - properly document Coro::EV::timed_io_once.
39 - avoid unneccessary ->cancel calls in Coro::Handle.
40 - maybe make it work on mingw32 with win32 backend
41 (based on patch by Yasuhiro Matsumoto).
42
435.132 Fri May 29 09:00:39 CEST 2009
44 - do not keep a reference to the argument itself in
45 Coro::Semaphore::guard, as it could change later.
46 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
47 should support a prepare callback.
48
495.131 Mon Mar 16 23:20:37 CET 2009
50 - implement and document Coro->suspend, Coro->resume.
51 - fix Coro::Select implementation to not (often) close
52 the passed file descriptors (testcase provided by pippijn).
53
545.13 Mon Dec 15 21:51:42 CET 2008
55 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
56 - don't set diehook to C<undef> but instead to NULL, to avoid
57 spurious warnings.
58 - fix a lot of bugs in Coro::SemaphoreSet.
59 - Coro::SemaphoreSet will less often create a semaphore needlessly.
60 - add Coro::SemaphoreSet::count and wait methods.
61 - take advantage of the new Guard module.
62 - deprecate Coro::guard.
63 - try to fix the dreaded 01_unblock tests once more. I hate it when
64 testsuites need more fixing than the code they are supposed to test.
65 - croak in more cases when a required callback isn't resolvable.
66 - fix some minor issues in Coro::State->call/eval.
67 - use current coroutine context instead of a temporary one
68 when temporarily switching to another coroutine.
69 - do not call C-level on_destroy handlers during global destruction,
70 to avoid needless segfaults.
71
725.12 Sun Dec 7 13:30:38 CET 2008
73 - add default config for MirOS, which seems to be a bug-to-bug
74 compatible fork of openbsd ("world domination by releasing
75 openbsd cvs before the openbsd folks do it" or so :).
76 - free_padlist did destroy the names pad, not good, but didn't
77 seem to bother perl - this could fix issues such as eval ""
78 inside a function called from multiple coroutines.
79 - use a different method to detect destruction time.
80 - be more careful when freeing padlists just before global
81 destruction.
82 - fixed and expanded the call/cc example.
83 - renamed _terminate to _coro_run.
84 - new method Coro::Channel->shutdown.
85 - try pthreads on openbsd <4.4 (broken sigaltstack, will
86 pthreads fare better?).
87 - be less picky about destroying "a" running coroutine.
88
895.11 Tue Nov 25 21:49:05 CET 2008
90 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
91 working code with failed assertions, introducing more bugs than
92 it fixes, requiring elaborate workarounds :(
93
945.1 Mon Nov 24 08:54:59 CET 2008
95 - wrote a small introductory tutorial - Coro::Intro.
96 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
97 - Coro::Select did errornously dup the file descriptors
98 and didn't work with all AnyEvent backends.
99 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
100 LWP data transfers.
101 - disassociate c contexts from coro objects - this is agruably more
102 correct, but mostly allows sharing of cctxs between coro and state
103 objects, for added memory savings and speed increases.
104 - bumped $Coro::POOL_RSS up to 32kb by default.
105 - no longer set the optype to OP_CUSTOM, as B::* understandably
106 doesn't like this very much (and we *are* a type of entersub).
107 - implement state cloning, just to prove that call/cc can be done.
108 - automatically load Coro::AnyEvent in Coro::Handle.
109 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
110 do not have this method (and don't need it either).
111 - speed up generic anyevent methods in Coro::Handle by using rouse
112 callbacks.
113 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
114 others. It also makes the debugger happier, as you can trace
115 through the idle threads now.
116 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
117 - eg/event was pretty broken.
118 - better 5.8.6 compatibility.
