125.0 135.132 Fri May 29 09:00:39 CEST 2009
14 - do not keep a reference to the argument itself in
15 Coro::Semaphore::guard, as it could change later.
16 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
17 should support a prepare callback.

195.131 Mon Mar 16 23:20:37 CET 2009
20 - implement and document Coro->suspend, Coro->resume.
21 - fix Coro::Select implementation to not (often) close
22 the passed file descriptors (testcase provided by pippijn).
23
245.13 Mon Dec 15 21:51:42 CET 2008
25 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
26 - don't set diehook to C<undef> but instead to NULL, to avoid
27 spurious warnings.
28 - fix a lot of bugs in Coro::SemaphoreSet.
29 - Coro::SemaphoreSet will less often create a semaphore needlessly.
30 - add Coro::SemaphoreSet::count and wait methods.
31 - take advantage of the new Guard module.
32 - deprecate Coro::guard.
33 - try to fix the dreaded 01_unblock tests once more. I hate it when
34 testsuites need more fixing than the code they are supposed to test.
35 - croak in more cases when a required callback isn't resolvable.
36 - fix some minor issues in Coro::State->call/eval.
37 - use current coroutine context instead of a temporary one
38 when temporarily switching to another coroutine.
39 - do not call C-level on_destroy handlers during global destruction,
40 to avoid needless segfaults.
41
425.12 Sun Dec 7 13:30:38 CET 2008
43 - add default config for MirOS, which seems to be a bug-to-bug
44 compatible fork of openbsd ("world domination by releasing
45 openbsd cvs before the openbsd folks do it" or so :).
46 - free_padlist did destroy the names pad, not good, but didn't
47 seem to bother perl - this could fix issues such as eval ""
48 inside a function called from multiple coroutines.
49 - use a different method to detect destruction time.
50 - be more careful when freeing padlists just before global
51 destruction.
52 - fixed and expanded the call/cc example.
53 - renamed _terminate to _coro_run.
54 - new method Coro::Channel->shutdown.
55 - try pthreads on openbsd <4.4 (broken sigaltstack, will
56 pthreads fare better?).
57 - be less picky about destroying "a" running coroutine.
58
595.11 Tue Nov 25 21:49:05 CET 2008
60 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
61 working code with failed assertions, introducing more bugs than
62 it fixes, requiring elaborate workarounds :(
63
645.1 Mon Nov 24 08:54:59 CET 2008
65 - wrote a small introductory tutorial - Coro::Intro.
66 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
67 - Coro::Select did errornously dup the file descriptors
68 and didn't work with all AnyEvent backends.
69 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
70 LWP data transfers.
71 - disassociate c contexts from coro objects - this is agruably more
72 correct, but mostly allows sharing of cctxs between coro and state
73 objects, for added memory savings and speed increases.
74 - bumped $Coro::POOL_RSS up to 32kb by default.
75 - no longer set the optype to OP_CUSTOM, as B::* understandably
76 doesn't like this very much (and we *are* a type of entersub).
77 - implement state cloning, just to prove that call/cc can be done.
78 - automatically load Coro::AnyEvent in Coro::Handle.
79 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
80 do not have this method (and don't need it either).
81 - speed up generic anyevent methods in Coro::Handle by using rouse
82 callbacks.
83 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
84 others. It also makes the debugger happier, as you can trace
85 through the idle threads now.
86 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
87 - eg/event was pretty broken.
88 - better 5.8.6 compatibility.

109 - new functions Coro::rouse_cb and Coro::rouse_wait for easier

112 schedule or cede to a specific coroutine.

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

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