8TODO: testcancel 11 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
9TODO: guard as SLF - to avoid deadlocks. 12 as this seems to have been a difficult concept (poll, sleep, idle,
10 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 13 idle_upto).
14 - add Coro::AnyEvent::readable/writable functions.
15 - clarify Coro::EV/Event/AnyEvent manpages.
16 - free per-thread global scalars in the thread calling ->cancel, to
17 avoid crashes when $_, $@ etc., are magical but some of those
18 had already been freed.
19 - speed up ready queue management/context switching by using a linked
20 list instead of an array (~5-10%).
21 - implement "watch" command in Coro::Debug shells.
22 - for fun, implement time-slicing as an example in the manpage.
23 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
24 Coro::Event, use the normal AnyEvent handling instead of dieing
25 (the same is true for Coro::Handle).
26 - properly document Coro::EV::timed_io_once.
27 - avoid unneccessary ->cancel alls in Coro::Handle.

125.0 295.132 Fri May 29 09:00:39 CEST 2009
30 - do not keep a reference to the argument itself in
31 Coro::Semaphore::guard, as it could change later.
32 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
33 should support a prepare callback.
34
355.131 Mon Mar 16 23:20:37 CET 2009
36 - implement and document Coro->suspend, Coro->resume.
37 - fix Coro::Select implementation to not (often) close
38 the passed file descriptors (testcase provided by pippijn).
39
405.13 Mon Dec 15 21:51:42 CET 2008
41 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
42 - don't set diehook to C<undef> but instead to NULL, to avoid
43 spurious warnings.
44 - fix a lot of bugs in Coro::SemaphoreSet.
45 - Coro::SemaphoreSet will less often create a semaphore needlessly.
46 - add Coro::SemaphoreSet::count and wait methods.
47 - take advantage of the new Guard module.
48 - deprecate Coro::guard.
49 - try to fix the dreaded 01_unblock tests once more. I hate it when
50 testsuites need more fixing than the code they are supposed to test.
51 - croak in more cases when a required callback isn't resolvable.
52 - fix some minor issues in Coro::State->call/eval.
53 - use current coroutine context instead of a temporary one
54 when temporarily switching to another coroutine.
55 - do not call C-level on_destroy handlers during global destruction,
56 to avoid needless segfaults.
57
585.12 Sun Dec 7 13:30:38 CET 2008
59 - add default config for MirOS, which seems to be a bug-to-bug
60 compatible fork of openbsd ("world domination by releasing
61 openbsd cvs before the openbsd folks do it" or so :).
62 - free_padlist did destroy the names pad, not good, but didn't
63 seem to bother perl - this could fix issues such as eval ""
64 inside a function called from multiple coroutines.
65 - use a different method to detect destruction time.
66 - be more careful when freeing padlists just before global
67 destruction.
68 - fixed and expanded the call/cc example.
69 - renamed _terminate to _coro_run.
70 - new method Coro::Channel->shutdown.
71 - try pthreads on openbsd <4.4 (broken sigaltstack, will
72 pthreads fare better?).
73 - be less picky about destroying "a" running coroutine.
74
755.11 Tue Nov 25 21:49:05 CET 2008
76 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
77 working code with failed assertions, introducing more bugs than
78 it fixes, requiring elaborate workarounds :(
79
805.1 Mon Nov 24 08:54:59 CET 2008
81 - wrote a small introductory tutorial - Coro::Intro.
82 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
83 - Coro::Select did errornously dup the file descriptors
84 and didn't work with all AnyEvent backends.
85 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
86 LWP data transfers.
87 - disassociate c contexts from coro objects - this is agruably more
88 correct, but mostly allows sharing of cctxs between coro and state
89 objects, for added memory savings and speed increases.
90 - bumped $Coro::POOL_RSS up to 32kb by default.
91 - no longer set the optype to OP_CUSTOM, as B::* understandably
92 doesn't like this very much (and we *are* a type of entersub).
93 - implement state cloning, just to prove that call/cc can be done.
94 - automatically load Coro::AnyEvent in Coro::Handle.
95 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
96 do not have this method (and don't need it either).
97 - speed up generic anyevent methods in Coro::Handle by using rouse
98 callbacks.
99 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
100 others. It also makes the debugger happier, as you can trace
101 through the idle threads now.
102 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
103 - eg/event was pretty broken.
104 - better 5.8.6 compatibility.

33 - new functions Coro::rouse_cb and Coro::rouse_wait. 125 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
126 conversion of callback-style to blocking-style.
127 - new methods $coro->schedule_to and ->cede_to, to specifically

155 - used new SLF interface and other optimisations to speed up async_pool
156 by a factor of two. It also doesn't rely on perl's exception mechanism
157 to exit anymore. The overhead for terminating an async_pool, coro over
158 a normal async is now very small.
