8TODO: testcancel 115.16 Tue Jul 21 01:44:37 CEST 2009
9TODO: guard as SLF - to avoid deadlocks. 12 - Coro::AnyEvent failed to hook into the event loop
10 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 13 when no threads had been readied between detecting
14 the event loop and actually running it.
15 - considerably speed up Coro::Select by taking avdantage
16 of AnyEvent > 4.8 and some other optimisations.
17 - implement paragraph readline mode in Coro::Handle
18 (based on patches by Zsbán Ambrus).
19 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
20 and analyzed by Yasuhiro MATSUMOTO).
21 - clarified libcoro license and copyright.
22 - someone stole my EXTRA_META!!!
23 - implement Coro::Select::patch_pp_sselect and it's brother,
24 for hardcode select overriding.

125.0 265.151 Mon Jul 6 05:41:57 CEST 2009
27 - backport to windows process emulation code again (patch by
28 Yasuhiro MATSUMOTO).
29 - slightly update Coro::MakeMaker.
30
315.15 Tue Jun 30 10:28:06 CEST 2009
32 - deprecate Coro::Socket, document how to get ipv6 support via
33 AnyEvent::Socket instead.
34 - implement signal->wait ($cb) interface, similar to semaphores.
35 - work around SvOK not supporting getmagic, so we have to getmagic
36 to test for undef :/ (reported by Matthias Waldorf).
37 - load Coro::AnyEvent in all modules using AnyEvent.
38 - work around perl corrupting our internal data structures,
39 reported by Tokuhiro Matsuno.
40 - enable per-coroutine real and cpu time gathering
41 (Coro::State::enable_times).
42
435.14 Wed Jun 24 01:37:48 CEST 2009
44 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
45 as this seems to have been a difficult concept (poll, sleep, idle,
46 idle_upto).
47 - add Coro::AnyEvent::readable/writable functions.
48 - clarify Coro::EV/Event/AnyEvent manpages.
49 - free per-thread global scalars in the thread calling ->cancel, to
50 avoid crashes when $_, $@ etc., are magical but some of those
51 had already been freed.
52 - "unexperimentalise" the callback interface for Coro::Semaphore.
53 - speed up ready queue management/context switching by using a linked
54 list instead of an array (~5-10%).
55 - implement "watch" command in Coro::Debug shells.
56 - for fun, implement time-slicing as an example in the manpage.
57 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
58 Coro::Event, use the normal AnyEvent handling instead of dieing
59 (the same is true for Coro::Handle).
60 - properly document Coro::EV::timed_io_once.
61 - avoid unneccessary ->cancel calls in Coro::Handle.
62 - maybe make it work on mingw32 with win32 backend
63 (based on patch by Yasuhiro Matsumoto).
64
655.132 Fri May 29 09:00:39 CEST 2009
66 - do not keep a reference to the argument itself in
67 Coro::Semaphore::guard, as it could change later.
68 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
69 should support a prepare callback.
70
715.131 Mon Mar 16 23:20:37 CET 2009
72 - implement and document Coro->suspend, Coro->resume.
73 - fix Coro::Select implementation to not (often) close
74 the passed file descriptors (testcase provided by pippijn).
75
765.13 Mon Dec 15 21:51:42 CET 2008
77 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
78 - don't set diehook to C<undef> but instead to NULL, to avoid
79 spurious warnings.
80 - fix a lot of bugs in Coro::SemaphoreSet.
81 - Coro::SemaphoreSet will less often create a semaphore needlessly.
82 - add Coro::SemaphoreSet::count and wait methods.
83 - take advantage of the new Guard module.
84 - deprecate Coro::guard.
85 - try to fix the dreaded 01_unblock tests once more. I hate it when
86 testsuites need more fixing than the code they are supposed to test.
87 - croak in more cases when a required callback isn't resolvable.
88 - fix some minor issues in Coro::State->call/eval.
89 - use current coroutine context instead of a temporary one
90 when temporarily switching to another coroutine.
91 - do not call C-level on_destroy handlers during global destruction,
92 to avoid needless segfaults.
93
945.12 Sun Dec 7 13:30:38 CET 2008
95 - add default config for MirOS, which seems to be a bug-to-bug
96 compatible fork of openbsd ("world domination by releasing
97 openbsd cvs before the openbsd folks do it" or so :).
98 - free_padlist did destroy the names pad, not good, but didn't
99 seem to bother perl - this could fix issues such as eval ""
100 inside a function called from multiple coroutines.
101 - use a different method to detect destruction time.
102 - be more careful when freeing padlists just before global
103 destruction.
104 - fixed and expanded the call/cc example.
105 - renamed _terminate to _coro_run.
106 - new method Coro::Channel->shutdown.
107 - try pthreads on openbsd <4.4 (broken sigaltstack, will
108 pthreads fare better?).
109 - be less picky about destroying "a" running coroutine.
110
1115.11 Tue Nov 25 21:49:05 CET 2008
112 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
113 working code with failed assertions, introducing more bugs than
114 it fixes, requiring elaborate workarounds :(
115
1165.1 Mon Nov 24 08:54:59 CET 2008
117 - wrote a small introductory tutorial - Coro::Intro.
118 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
119 - Coro::Select did errornously dup the file descriptors
120 and didn't work with all AnyEvent backends.
121 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
122 LWP data transfers.
123 - disassociate c contexts from coro objects - this is agruably more
124 correct, but mostly allows sharing of cctxs between coro and state
125 objects, for added memory savings and speed increases.
126 - bumped $Coro::POOL_RSS up to 32kb by default.
127 - no longer set the optype to OP_CUSTOM, as B::* understandably
128 doesn't like this very much (and we *are* a type of entersub).
129 - implement state cloning, just to prove that call/cc can be done.
130 - automatically load Coro::AnyEvent in Coro::Handle.
131 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
132 do not have this method (and don't need it either).
133 - speed up generic anyevent methods in Coro::Handle by using rouse
134 callbacks.
135 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
136 others. It also makes the debugger happier, as you can trace
137 through the idle threads now.
138 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
139 - eg/event was pretty broken.
140 - better 5.8.6 compatibility.

161 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
162 conversion of callback-style to blocking-style.
163 - new methods $coro->schedule_to and ->cede_to, to specifically
164 schedule or cede to a specific coroutine.

56 making signals reliable for the first time. 190 making signals reliable for the first time.
191 - used new SLF interface and other optimisations to speed up async_pool
192 by a factor of two. It also doesn't rely on perl's exception mechanism
193 to exit anymore. The overhead for terminating an async_pool, coro over
194 a normal async is now very small.
195 - sped up coroutine creation/destruction by 40%.

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