85.0 105.0
9 - NEW ARCHITECTURE: use 4.912 for the stable version. 11 - NEW ARCHITECTURE: use the latest 4.x version if you experience
12 stability issues.
10 - bump API version to 7 - all dependents must be recompiled. 13 - bump API version to 7 - all dependents must be recompiled.
14 - removed timed_* functions - they were not being used anyways
15 and should be replaced by a more generic mechanism -
16 and were annoying to support anyways :)
17 - removed SemaphoreSet's waiter method - use sem instead.
11 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 18 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
12 - async_pool did free a scalar value twice 19 - async_pool did free a scalar value twice
13 ("Attempt to unreference..."). 20 ("Attempt to unreference...").
21 - fix a disastrous bug in the readline optimisation
22 introduced in 4.801.
23 - fix a longstanding bug where calling terminate on a coro that
24 was waiting for a semaphore that was just becoming available
25 would cause a deadlock (semaphore would get into a state where
26 it was available but waiters were still blocked).
27 - calling throw on a coroutine that is waiting for a semaphore will
28 no longer make it acquire the semaphore (and thus leak a count).
14 - perl's process emulation is now not even theoretically supported 29 - perl's process emulation is now not even theoretically supported
15 anymore. 30 anymore.
31 - new functions Coro::rouse_cb and Coro::rouse_wait.
32 - new function Coro::Semaphore::wait.
33 - use named constants in Coro::Channel (Richard Hundt).
16 - directly patch the entersub opcode calling SLF functions (cede, 34 - directly patch the entersub opcode calling SLF functions (cede,
17 transfer and so on). this does speed up context switching, but 35 transfer and so on). this does speed up context switching, but
18 more importanly, it frees us from the hardcoded behaviour of 36 more importanly, it frees us from the hardcoded behaviour of
19 entersub, so we might actually be able to return something from 37 entersub, so we might actually be able to return something from
20 those functions and atcually create new ones. 38 those functions and atcually create new ones.
21 - take advantage of __builtin_frame_address on gcc. 39 - take advantage of __builtin_frame_address on gcc.
22 - expose THX in coroapi (not sure whether this was a wise decision, 40 - expose THX in coroapi (not sure whether this was a wise decision,
23 as "threaded" perls are running at half speed anyways). 41 as "threaded" perls are running at half speed anyways).
24 - implement execute_slf (schedule-like-function) interface that makes 42 - implement execute_slf (schedule-like-function) interface that makes
25 it possible to implement schedule-like-functions in XS. 43 it possible to implement schedule-like-functions in XS.
26 - use new SLF interface to massively speed up Coro::EV by roughly a factor 44 - use new SLF interface to massively speed up Coro::EV by roughly a
27 of two. 45 factor of two.
28 - removed timed_down and timed_guard functions - they were not being used
29 anyways and should be replaced by a more generic mechanism - and were
30 annoying to support anyways :
31 - used new SLF interface to massively speed up Coro::Semaphore by a factor 46 - used new SLF interface to massively speed up Coro::Semaphore by a
32 of three. 47 factor of three.
48 - used new SLF interface to speed up Coro::AIO by roughly a factor of
49 four and reduce its memory usage considerably.
50 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
51 for a nice speedup and vastly more correct behaviour. Also implement
52 a new method "sem" to get at the underlying semaphore object.
53 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
54 (in comparison) 20-40% speedup.
55 - used new SLF interface to reimplement Coro::Signal gaining
56 some unknown (because I was too lazy), but certain, speedup, and also
57 making signals reliable for the first time.
58 - used new SLF interface and other optimisations to speed up async_pool
59 by a factor of two. It also doesn't rely on perl's exception mechanism
60 to exit anymore. The overhead for terminating an async_pool, coro over
61 a normal async is now very small.
62 - sped up coroutine creation/destruction by 40%.
63 - forgot to include Coro/libcoro/README in the dist for all these years.
64 - work around a freebsd pthreads bug (manual testcancel is required as
65 pthread_cond_wait isn't a cancellation point on freebsd).
66 - use new rouse functions to speed up and simplify Coro::BDB.
67 - make "prefer perl native functions" work with threaded perls.
68 - condense Coro::Debug ps output, hint at v and w flags.
69 - (libcoro) lots of minor cleanups and portability improvements.
