12 - NEW ARCHITECTURE: use 4.912 for the stable version. 9 - NEW ARCHITECTURE: use the latest 4.x version if you experience
10 stability issues.
13 - bump API version to 7 - all dependents must be recompiled. 11 - bump API version to 7 - all dependents must be recompiled.
12 - removed timed_* functions - they were not being used anyways
13 and should be replaced by a more generic mechanism -
14 and were annoying to support anyways :)
15 - removed SemaphoreSet's waiter method - use sem instead.
14 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 16 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
15 - async_pool did free a scalar value twice 17 - async_pool did free a scalar value twice
16 ("Attempt to unreference..."). 18 ("Attempt to unreference...").
19 - fix a disastrous bug in the readline optimisation
20 introduced in 4.801.
21 - fix a longstanding bug where calling terminate on a coro that
22 was waiting for a semaphore that was just becoming available
23 would cause a deadlock (semaphore would get into a state where
24 it was available but waiters were still blocked).
25 - calling throw on a coroutine that is waiting for a semaphore will
26 no longer make it acquire the semaphore (and thus leak a count).
17 - perl's process emulation is now not even theoretically supported 27 - perl's process emulation is now not even theoretically supported
18 anymore. 28 anymore.
29 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
30 conversion of callback-style to blocking-style.
31 - new methods $coro->schedule_to and ->cede_to, to specifically
32 schedule or cede to a specific coroutine.
33 - new function Coro::Semaphore::wait.
34 - use named constants in Coro::Channel (Richard Hundt).
19 - directly patch the entersub opcode calling SLF functions (cede, 35 - directly patch the entersub opcode calling SLF functions (cede,
20 transfer and so on). this does speed up context switching, but 36 transfer and so on). this does speed up context switching, but
21 more importanly, it frees us from the hardcoded behaviour of 37 more importanly, it frees us from the hardcoded behaviour of
22 entersub, so we might actually be able to return something from 38 entersub, so we might actually be able to return something from
23 those functions and atcually create new ones. 39 those functions and atcually create new ones.
24 - take advantage of __builtin_frame_address on gcc. 40 - take advantage of __builtin_frame_address on gcc.
25 - expose THX in coroapi (not sure whether this was a wise decision, 41 - expose THX in coroapi (not sure whether this was a wise decision,
26 as "threaded" perls are running at half speed anyways). 42 as "threaded" perls are running at half speed anyways).
27 - implement execute_slf (schedule-like-function) interface that makes 43 - implement execute_slf (schedule-like-function) interface that makes
28 it possible to implement schedule-like-functions in XS. 44 it possible to implement schedule-like-functions in XS.
29 - use new SLF interface to massively speed up Coro::EV by roughly a factor 45 - use new SLF interface to massively speed up Coro::EV by roughly a
30 of two. 46 factor of two.
31 - removed timed_down and timed_guard functions - they were not being used
32 anyways and should be replaced by a more generic mechanism - and were
33 annoying to support anyways :
34 - used new SLF interface to massively speed up Coro::Semaphore by a factor 47 - used new SLF interface to massively speed up Coro::Semaphore by a
35 of three. 48 factor of three.
49 - used new SLF interface to speed up Coro::AIO by roughly a factor of
50 four and reduce its memory usage considerably.
51 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
52 for a nice speedup and vastly more correct behaviour. Also implement
53 a new method "sem" to get at the underlying semaphore object.
54 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
55 (in comparison) 20-40% speedup.
56 - used new SLF interface to reimplement Coro::Signal gaining
57 some unknown (because I was too lazy), but certain, speedup, and also
58 making signals reliable for the first time.
59 - used new SLF interface and other optimisations to speed up async_pool
60 by a factor of two. It also doesn't rely on perl's exception mechanism
61 to exit anymore. The overhead for terminating an async_pool, coro over
62 a normal async is now very small.
63 - sped up coroutine creation/destruction by 40%.
36 - forgot to include Coro/libcoro/README in the dist for all these years. 64 - forgot to include Coro/libcoro/README in the dist for all these years.
37 - work around a freebsd pthreads bug (manual testcancel is required as 65 - work around a freebsd pthreads bug (manual testcancel is required as
38 pthread_cond_wait isn't a cancellation point on freebsd). 66 pthread_cond_wait isn't a cancellation point on freebsd).
67 - use new rouse functions to speed up and simplify Coro::BDB.
68 - make "prefer perl native functions" work with threaded perls.
69 - condense Coro::Debug ps output, hint at v and w flags.
70 - (libcoro) lots of minor cleanups and portability improvements.
