85.0 8 - minor tuning.

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

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

415.0 Thu Nov 20 10:35:05 CET 2008
42 - NEW ARCHITECTURE: use the latest 4.x version if you experience
43 stability issues.
10 - bump API version to 7 - all dependents must be recompiled. 44 - bump API version to 7 - all dependents must be recompiled.
45 - removed timed_* functions - they were not being used anyways
46 and should be replaced by a more generic mechanism -
47 and were annoying to support anyways :)
48 - removed SemaphoreSet's waiter method - use sem method instead.
11 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 49 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
12 - async_pool did free a scalar value twice 50 - async_pool did free a scalar value twice
13 ("Attempt to unreference..."). 51 ("Attempt to unreference...").
52 - fix a longstanding bug where calling terminate on a coro that
53 was waiting for a semaphore that was just becoming available
54 would cause a deadlock (semaphore would get into a state where
55 it was available but waiters were still blocked).
56 - calling throw on a coroutine that is waiting for a semaphore will
57 no longer make it acquire the semaphore (and thus leak a count).
14 - perl's process emulation is now not even theoretically supported 58 - perl's process emulation is now not even theoretically supported
15 anymore. 59 anymore.
60 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
61 conversion of callback-style to blocking-style.
62 - new methods $coro->schedule_to and ->cede_to, to specifically
63 schedule or cede to a specific coroutine.
64 - new function Coro::Semaphore::wait.
65 - use named constants in Coro::Channel (Richard Hundt).
16 - directly patch the entersub opcode calling SLF functions (cede, 66 - directly patch the entersub opcode calling SLF functions (cede,
17 transfer and so on). this does speed up context switching, but 67 transfer and so on). this does speed up context switching, but
18 more importanly, it frees us from the hardcoded behaviour of 68 more importanly, it frees us from the hardcoded behaviour of
19 entersub, so we might actually be able to return something from 69 entersub, so we might actually be able to return something from
20 those functions and atcually create new ones. 70 those functions and atcually create new ones.
21 - take advantage of __builtin_frame_address on gcc. 71 - take advantage of __builtin_frame_address on gcc.
22 - expose THX in coroapi (not sure whether this was a wise decision, 72 - expose THX in coroapi (not sure whether this was a wise decision,
23 as "threaded" perls are running at half speed anyways). 73 as "threaded" perls are running at half speed anyways).
24 - implement execute_slf (schedule-like-function) interface that makes 74 - implement execute_slf (schedule-like-function) interface that makes
25 it possible to implement schedule-like-functions in XS. 75 it possible to implement schedule-like-functions in XS.
26 - use new SLF interface to massively speed up Coro::EV by roughly a factor 76 - use new SLF interface to massively speed up Coro::EV by roughly a
27 of two. 77 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 78 - used new SLF interface to massively speed up Coro::Semaphore by a
32 of three. 79 factor of three.
80 - used new SLF interface to speed up Coro::AIO by roughly a factor of
81 four and reduce its memory usage considerably.
82 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
83 for a nice speedup and vastly more correct behaviour. Also implement
84 a new method "sem" to get at the underlying semaphore object.
85 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
86 (in comparison) 20-40% speedup.
87 - used new SLF interface to reimplement Coro::Signal gaining
88 some unknown (because I was too lazy), but certain, speedup, and also
89 making signals reliable for the first time.
90 - used new SLF interface and other optimisations to speed up async_pool
91 by a factor of two. It also doesn't rely on perl's exception mechanism
92 to exit anymore. The overhead for terminating an async_pool, coro over
93 a normal async is now very small.
94 - sped up coroutine creation/destruction by 40%.
33 - forgot to include Coro/libcoro/README in the dist for all these years. 95 - forgot to include Coro/libcoro/README in the dist for all these years.
96 - work around a freebsd pthreads bug (manual testcancel is required as
97 pthread_cond_wait isn't a cancellation point on freebsd).
98 - use new rouse functions to speed up and simplify Coro::BDB.
99 - make "prefer perl native functions" work with threaded perls.
100 - condense Coro::Debug ps output, hint at v and w flags.
101 - (libcoro) lots of minor cleanups and portability improvements.

104 - fix a disastrous bug in the readline optimisation
105 introduced in 4.801.
