8TODO: testcancel 11 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
9TODO: aio 12 as this seems to have been a difficult concept (poll, sleep, idle,
10TODO: Coro::Semaphore 13 idle_upto).
11TODO: trow disturbs cleanup path inside pp_slf? 14 - add Coro::AnyEvent::readable/writable functions.
12TODO: throw special-case in transfer? 15 - clarify Coro::EV/Event/AnyEvent manpages.
135.0 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 - "unexperimentalize" the callback interface for Coro::Semaphore.
20 - speed up ready queue management/context switching by using a linked
21 list instead of an array (~5-10%).
22 - implement "watch" command in Coro::Debug shells.
23 - for fun, implement time-slicing as an example in the manpage.
24 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
25 Coro::Event, use the normal AnyEvent handling instead of dieing
26 (the same is true for Coro::Handle).
27 - properly document Coro::EV::timed_io_once.
28 - avoid unneccessary ->cancel calls in Coro::Handle.
29 - maybe make it work on mingw32 with win32 backend
30 (based on patch by Yasuhiro Matsumoto).
31
325.132 Fri May 29 09:00:39 CEST 2009
33 - do not keep a reference to the argument itself in
34 Coro::Semaphore::guard, as it could change later.
35 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
36 should support a prepare callback.
37
385.131 Mon Mar 16 23:20:37 CET 2009
39 - implement and document Coro->suspend, Coro->resume.
40 - fix Coro::Select implementation to not (often) close
41 the passed file descriptors (testcase provided by pippijn).
42
435.13 Mon Dec 15 21:51:42 CET 2008
44 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
45 - don't set diehook to C<undef> but instead to NULL, to avoid
46 spurious warnings.
47 - fix a lot of bugs in Coro::SemaphoreSet.
48 - Coro::SemaphoreSet will less often create a semaphore needlessly.
49 - add Coro::SemaphoreSet::count and wait methods.
50 - take advantage of the new Guard module.
51 - deprecate Coro::guard.
52 - try to fix the dreaded 01_unblock tests once more. I hate it when
53 testsuites need more fixing than the code they are supposed to test.
54 - croak in more cases when a required callback isn't resolvable.
55 - fix some minor issues in Coro::State->call/eval.
56 - use current coroutine context instead of a temporary one
57 when temporarily switching to another coroutine.
58 - do not call C-level on_destroy handlers during global destruction,
59 to avoid needless segfaults.
60
615.12 Sun Dec 7 13:30:38 CET 2008
62 - add default config for MirOS, which seems to be a bug-to-bug
63 compatible fork of openbsd ("world domination by releasing
64 openbsd cvs before the openbsd folks do it" or so :).
65 - free_padlist did destroy the names pad, not good, but didn't
66 seem to bother perl - this could fix issues such as eval ""
67 inside a function called from multiple coroutines.
68 - use a different method to detect destruction time.
69 - be more careful when freeing padlists just before global
70 destruction.
71 - fixed and expanded the call/cc example.
72 - renamed _terminate to _coro_run.
73 - new method Coro::Channel->shutdown.
74 - try pthreads on openbsd <4.4 (broken sigaltstack, will
75 pthreads fare better?).
76 - be less picky about destroying "a" running coroutine.
77
785.11 Tue Nov 25 21:49:05 CET 2008
79 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
80 working code with failed assertions, introducing more bugs than
81 it fixes, requiring elaborate workarounds :(
82
835.1 Mon Nov 24 08:54:59 CET 2008
84 - wrote a small introductory tutorial - Coro::Intro.
85 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
86 - Coro::Select did errornously dup the file descriptors
87 and didn't work with all AnyEvent backends.
88 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
89 LWP data transfers.
90 - disassociate c contexts from coro objects - this is agruably more
91 correct, but mostly allows sharing of cctxs between coro and state
92 objects, for added memory savings and speed increases.
93 - bumped $Coro::POOL_RSS up to 32kb by default.
94 - no longer set the optype to OP_CUSTOM, as B::* understandably
95 doesn't like this very much (and we *are* a type of entersub).
96 - implement state cloning, just to prove that call/cc can be done.
97 - automatically load Coro::AnyEvent in Coro::Handle.
98 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
99 do not have this method (and don't need it either).
100 - speed up generic anyevent methods in Coro::Handle by using rouse
101 callbacks.
102 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
103 others. It also makes the debugger happier, as you can trace
104 through the idle threads now.
105 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
106 - eg/event was pretty broken.
107 - better 5.8.6 compatibility.

15 stability issues. 111 stability issues.
16 - bump API version to 7 - all dependents must be recompiled. 112 - bump API version to 7 - all dependents must be recompiled.
113 - removed timed_* functions - they were not being used anyways
114 and should be replaced by a more generic mechanism -
115 and were annoying to support anyways :)
116 - removed SemaphoreSet's waiter method - use sem method instead.
17 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 117 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.

21 was waiting for a semaphore that was just becoming available 121 was waiting for a semaphore that was just becoming available
22 would cause a deadlock (semaphore would get into a state where 122 would cause a deadlock (semaphore would get into a state where
23 it was available but waiters were waiting(. 123 it was available but waiters were still blocked).
24 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 124 - calling throw on a coroutine that is waiting for a semaphore will
125 no longer make it acquire the semaphore (and thus leak a count).
25 - perl's process emulation is now not even theoretically supported 126 - perl's process emulation is now not even theoretically supported
26 anymore. 127 anymore.
128 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
129 conversion of callback-style to blocking-style.
130 - new methods $coro->schedule_to and ->cede_to, to specifically
131 schedule or cede to a specific coroutine.
132 - new function Coro::Semaphore::wait.
133 - use named constants in Coro::Channel (Richard Hundt).
27 - directly patch the entersub opcode calling SLF functions (cede, 134 - directly patch the entersub opcode calling SLF functions (cede,
28 transfer and so on). this does speed up context switching, but 135 transfer and so on). this does speed up context switching, but

38 factor of two. 145 factor of two.

44 - used new SLF interface to speed up Coro::AIO by roughly a factor of 148 - used new SLF interface to speed up Coro::AIO by roughly a factor of
45 four and reduce its memory usage considerably. 149 four and reduce its memory usage considerably.
150 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
151 for a nice speedup and vastly more correct behaviour. Also implement
152 a new method "sem" to get at the underlying semaphore object.
153 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
154 (in comparison) 20-40% speedup.
155 - used new SLF interface to reimplement Coro::Signal gaining
156 some unknown (because I was too lazy), but certain, speedup, and also
157 making signals reliable for the first time.
158 - used new SLF interface and other optimisations to speed up async_pool
159 by a factor of two. It also doesn't rely on perl's exception mechanism
160 to exit anymore. The overhead for terminating an async_pool, coro over
161 a normal async is now very small.
162 - sped up coroutine creation/destruction by 40%.
46 - forgot to include Coro/libcoro/README in the dist for all these years. 163 - forgot to include Coro/libcoro/README in the dist for all these years.

48 pthread_cond_wait isn't a cancellation point on freebsd). 165 pthread_cond_wait isn't a cancellation point on freebsd).
166 - use new rouse functions to speed up and simplify Coro::BDB.
167 - make "prefer perl native functions" work with threaded perls.
168 - condense Coro::Debug ps output, hint at v and w flags.
169 - (libcoro) lots of minor cleanups and portability improvements.
