8TODO: testcancel 85.13
9TODO: guard as SLF - to avoid deadlocks. 9 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
10 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 10 - don't set diehook to C<undef> but instead to NULL, to avoid
11 spurious warnings.
12 - fix a lot of bugs in Coro::SemaphoreSet.
13 - Coro::SemaphoreSet will less often create a semaphore needlessly.
14 - add Coro::SemaphoreSet::count and wait methods.
15 - take advantage of the new Guard module.
16 - deprecate Coro::guard.
17 - try to fix the dreaded 01_unblock tests once more. I hate it when
18 testsuites need more fixing than the code they are supposed to test.
19 - croak in more cases when a required callback isn't resolvable.
20 - fix some minor issues in Coro::State->call/eval.
21 - use current coroutine context instead of a temporary one
22 when temporarily switching to another coroutine.
23 - do not call C-level on_destroy handlers during global destruction.

125.0 255.12 Sun Dec 7 13:30:38 CET 2008
26 - add default config for MirOS, which seems to be a bug-to-bug
27 compatible fork of openbsd ("world domination by releasing
28 openbsd cvs before the openbsd folks do it" or so :).
29 - free_padlist did destroy the names pad, not good, but didn't
30 seem to bother perl - this could fix issues such as eval ""
31 inside a function called from multiple coroutines.
32 - use a different method to detect destruction time.
33 - be more careful when freeing padlists just before global
34 destruction.
35 - fixed and expanded the call/cc example.
36 - renamed _terminate to _coro_run.
37 - new method Coro::Channel->shutdown.
38 - try pthreads on openbsd <4.4 (broken sigaltstack, will
39 pthreads fare better?).
40 - be less picky about destroying "a" running coroutine.

425.11 Tue Nov 25 21:49:05 CET 2008
43 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
44 working code with failed assertions, introducing more bugs than
45 it fixes, requiring elaborate workarounds :(

475.1 Mon Nov 24 08:54:59 CET 2008
48 - wrote a small introductory tutorial - Coro::Intro.
49 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
50 - Coro::Select did errornously dup the file descriptors
51 and didn't work with all AnyEvent backends.
52 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
53 LWP data transfers.
54 - disassociate c contexts from coro objects - this is agruably more
55 correct, but mostly allows sharing of cctxs between coro and state
56 objects, for added memory savings and speed increases.
57 - bumped $Coro::POOL_RSS up to 32kb by default.
58 - no longer set the optype to OP_CUSTOM, as B::* understandably
59 doesn't like this very much (and we *are* a type of entersub).
60 - implement state cloning, just to prove that call/cc can be done.
61 - automatically load Coro::AnyEvent in Coro::Handle.
62 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
63 do not have this method (and don't need it either).
64 - speed up generic anyevent methods in Coro::Handle by using rouse
65 callbacks.
66 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
67 others. It also makes the debugger happier, as you can trace
68 through the idle threads now.
69 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
70 - eg/event was pretty broken.
71 - better 5.8.6 compatibility.

14 stability issues. 75 stability issues.
15 - bump API version to 7 - all dependents must be recompiled. 76 - bump API version to 7 - all dependents must be recompiled.

19 - removed SemaphoreSet's waiter method - use sem instead. 80 - removed SemaphoreSet's waiter method - use sem method instead.
20 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 81 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
21 - async_pool did free a scalar value twice 82 - async_pool did free a scalar value twice

23 - fix a longstanding bug where calling terminate on a coro that 84 - fix a longstanding bug where calling terminate on a coro that
24 was waiting for a semaphore that was just becoming available 85 was waiting for a semaphore that was just becoming available
25 would cause a deadlock (semaphore would get into a state where 86 would cause a deadlock (semaphore would get into a state where
26 it was available but waiters were waiting(. 87 it was available but waiters were still blocked).
88 - calling throw on a coroutine that is waiting for a semaphore will
89 no longer make it acquire the semaphore (and thus leak a count).
27 - perl's process emulation is now not even theoretically supported 90 - perl's process emulation is now not even theoretically supported
28 anymore. 91 anymore.
92 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
93 conversion of callback-style to blocking-style.
94 - new methods $coro->schedule_to and ->cede_to, to specifically
95 schedule or cede to a specific coroutine.
96 - new function Coro::Semaphore::wait.
29 - use named constants in Coro::Channel (Richard Hundt). 97 - use named constants in Coro::Channel (Richard Hundt).
30 - directly patch the entersub opcode calling SLF functions (cede, 98 - directly patch the entersub opcode calling SLF functions (cede,
31 transfer and so on). this does speed up context switching, but 99 transfer and so on). this does speed up context switching, but
32 more importanly, it frees us from the hardcoded behaviour of 100 more importanly, it frees us from the hardcoded behaviour of
33 entersub, so we might actually be able to return something from 101 entersub, so we might actually be able to return something from
46 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, 114 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
47 for a nice speedup and vastly more correct behaviour. Also implement 115 for a nice speedup and vastly more correct behaviour. Also implement
48 a new method "sem" to get at the underlying semaphore object. 116 a new method "sem" to get at the underlying semaphore object.
49 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate 117 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
50 (in comparison) 20-40% speedup. 118 (in comparison) 20-40% speedup.
119 - used new SLF interface to reimplement Coro::Signal gaining
120 some unknown (because I was too lazy), but certain, speedup, and also
121 making signals reliable for the first time.
122 - used new SLF interface and other optimisations to speed up async_pool
123 by a factor of two. It also doesn't rely on perl's exception mechanism
124 to exit anymore. The overhead for terminating an async_pool, coro over
125 a normal async is now very small.
126 - sped up coroutine creation/destruction by 40%.
51 - forgot to include Coro/libcoro/README in the dist for all these years. 127 - forgot to include Coro/libcoro/README in the dist for all these years.

53 pthread_cond_wait isn't a cancellation point on freebsd). 129 pthread_cond_wait isn't a cancellation point on freebsd).
130 - use new rouse functions to speed up and simplify Coro::BDB.
131 - make "prefer perl native functions" work with threaded perls.
132 - condense Coro::Debug ps output, hint at v and w flags.
133 - (libcoro) lots of minor cleanups and portability improvements.

136 - fix a disastrous bug in the readline optimisation
137 introduced in 4.801.
