8TODO: testcancel 85.1 Mon Nov 24 08:54:59 CET 2008
9TODO: guard as SLF - to avoid deadlocks. 9 - wrote a small introductory tutorial - Coro::Intro.
10TODO: Coro::Signal as SLF. 10 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
11 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 11 - Coro::Select did errornously dup the file descriptors
12 and didn't work with all AnyEvent backends.
13 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
14 LWP data transfers.
15 - disassociate c contexts from coro objects - this is agruably more
16 correct, but mostly allows sharing of cctxs between coro and state
17 objects, for added memory savings and speed increases.
18 - bumped $Coro::POOL_RSS up to 32kb by default.
19 - no longer set the optype to OP_CUSTOM, as B::* understandably
20 doesn't like this very much (and we *are* a type of entersub).
21 - implement state cloning, just to prove that call/cc can be done.
22 - automatically load Coro::AnyEvent in Coro::Handle.
23 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
24 do not have this method (and don't need it either).
25 - speed up generic anyevent methods in Coro::Handle by using rouse
26 callbacks.
27 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
28 others. It also makes the debugger happier, as you can trace
29 through the idle threads now.
30 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
31 - eg/event was pretty broken.
32 - better 5.8.6 compatibility.

25 was waiting for a semaphore that was just becoming available 46 was waiting for a semaphore that was just becoming available
26 would cause a deadlock (semaphore would get into a state where 47 would cause a deadlock (semaphore would get into a state where
27 it was available but waiters were waiting(. 48 it was available but waiters were still blocked).
49 - calling throw on a coroutine that is waiting for a semaphore will
50 no longer make it acquire the semaphore (and thus leak a count).
28 - perl's process emulation is now not even theoretically supported 51 - perl's process emulation is now not even theoretically supported
29 anymore. 52 anymore.
53 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
54 conversion of callback-style to blocking-style.
55 - new methods $coro->schedule_to and ->cede_to, to specifically
56 schedule or cede to a specific coroutine.
57 - new function Coro::Semaphore::wait.
30 - use named constants in Coro::Channel (Richard Hundt). 58 - use named constants in Coro::Channel (Richard Hundt).

47 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, 75 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
48 for a nice speedup and vastly more correct behaviour. Also implement 76 for a nice speedup and vastly more correct behaviour. Also implement
49 a new method "sem" to get at the underlying semaphore object. 77 a new method "sem" to get at the underlying semaphore object.
50 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate 78 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
51 (in comparison) 20-40% speedup. 79 (in comparison) 20-40% speedup.
80 - used new SLF interface to reimplement Coro::Signal gaining
81 some unknown (because I was too lazy), but certain, speedup, and also
82 making signals reliable for the first time.
83 - used new SLF interface and other optimisations to speed up async_pool
84 by a factor of two. It also doesn't rely on perl's exception mechanism
85 to exit anymore. The overhead for terminating an async_pool, coro over
86 a normal async is now very small.
87 - sped up coroutine creation/destruction by 40%.
52 - forgot to include Coro/libcoro/README in the dist for all these years. 88 - forgot to include Coro/libcoro/README in the dist for all these years.
53 - work around a freebsd pthreads bug (manual testcancel is required as 89 - work around a freebsd pthreads bug (manual testcancel is required as
54 pthread_cond_wait isn't a cancellation point on freebsd). 90 pthread_cond_wait isn't a cancellation point on freebsd).
91 - use new rouse functions to speed up and simplify Coro::BDB.
92 - make "prefer perl native functions" work with threaded perls.
93 - condense Coro::Debug ps output, hint at v and w flags.
94 - (libcoro) lots of minor cleanups and portability improvements.
