195.12
20 - add default config for MirOS, which seems to be a bug-to-bug
21 compatible fork of openbsd ("world domination by releasing
22 openbsd cvs before the openbsd folks do it" or so :).
23 - free_padlist did destroy the names pad, not good, but didn't
24 seem to bother perl - this could fix issues such as eval ""
25 inside a function called form multiple coroutines.
26 - use a different method to detect destruction time.
27 - be more careful when freeing padlists just before global
28 destruction.
29 - fixed and expanded the call/cc example.
30 - renamed _terminate to _coro_run.
31 - new method Coro::Channel->shutdown.
32 - try pthreads on openbsd <4.4 (broken sigaltstack, will
33 pthreads fare better?).
34 - be less picky about destroying "a" running coroutine.

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

415.1 Mon Nov 24 08:54:59 CET 2008
42 - wrote a small introductory tutorial - Coro::Intro.
43 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
44 - Coro::Select did errornously dup the file descriptors
45 and didn't work with all AnyEvent backends.
46 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
47 LWP data transfers.
48 - disassociate c contexts from coro objects - this is agruably more
49 correct, but mostly allows sharing of cctxs between coro and state
50 objects, for added memory savings and speed increases.
51 - bumped $Coro::POOL_RSS up to 32kb by default.
52 - no longer set the optype to OP_CUSTOM, as B::* understandably
53 doesn't like this very much (and we *are* a type of entersub).
54 - implement state cloning, just to prove that call/cc can be done.
55 - automatically load Coro::AnyEvent in Coro::Handle.
56 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
57 do not have this method (and don't need it either).
58 - speed up generic anyevent methods in Coro::Handle by using rouse
59 callbacks.
60 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
61 others. It also makes the debugger happier, as you can trace
62 through the idle threads now.
63 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
64 - eg/event was pretty broken.
65 - better 5.8.6 compatibility.
66
675.0 Thu Nov 20 10:35:05 CET 2008
68 - NEW ARCHITECTURE: use the latest 4.x version if you experience
69 stability issues.
15 - bump API version to 7 - all dependents must be recompiled. 70 - bump API version to 7 - all dependents must be recompiled.
71 - removed timed_* functions - they were not being used anyways
72 and should be replaced by a more generic mechanism -
73 and were annoying to support anyways :)
74 - removed SemaphoreSet's waiter method - use sem method instead.
16 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 75 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
17 - async_pool did free a scalar value twice 76 - async_pool did free a scalar value twice
18 ("Attempt to unreference..."). 77 ("Attempt to unreference...").
19 - fix a longstanding bug where calling terminate on a coro that 78 - fix a longstanding bug where calling terminate on a coro that
20 was waiting for a semaphore that was just becoming available 79 was waiting for a semaphore that was just becoming available
21 would cause a deadlock (semaphore would get into a state where 80 would cause a deadlock (semaphore would get into a state where
22 it was available but waiters were waiting(. 81 it was available but waiters were still blocked).
23 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 82 - calling throw on a coroutine that is waiting for a semaphore will
83 no longer make it acquire the semaphore (and thus leak a count).
24 - perl's process emulation is now not even theoretically supported 84 - perl's process emulation is now not even theoretically supported
25 anymore. 85 anymore.
86 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
87 conversion of callback-style to blocking-style.
88 - new methods $coro->schedule_to and ->cede_to, to specifically
89 schedule or cede to a specific coroutine.
90 - new function Coro::Semaphore::wait.
91 - use named constants in Coro::Channel (Richard Hundt).
26 - directly patch the entersub opcode calling SLF functions (cede, 92 - directly patch the entersub opcode calling SLF functions (cede,
27 transfer and so on). this does speed up context switching, but 93 transfer and so on). this does speed up context switching, but
28 more importanly, it frees us from the hardcoded behaviour of 94 more importanly, it frees us from the hardcoded behaviour of
29 entersub, so we might actually be able to return something from 95 entersub, so we might actually be able to return something from
30 those functions and atcually create new ones. 96 those functions and atcually create new ones.
31 - take advantage of __builtin_frame_address on gcc. 97 - take advantage of __builtin_frame_address on gcc.
32 - expose THX in coroapi (not sure whether this was a wise decision, 98 - expose THX in coroapi (not sure whether this was a wise decision,
33 as "threaded" perls are running at half speed anyways). 99 as "threaded" perls are running at half speed anyways).
34 - implement execute_slf (schedule-like-function) interface that makes 100 - implement execute_slf (schedule-like-function) interface that makes
35 it possible to implement schedule-like-functions in XS. 101 it possible to implement schedule-like-functions in XS.
36 - use new SLF interface to massively speed up Coro::EV by roughly a factor 102 - use new SLF interface to massively speed up Coro::EV by roughly a
37 of two. 103 factor of two.
38 - removed timed_down and timed_guard functions - they were not being used
39 anyways and should be replaced by a more generic mechanism - and were
40 annoying to support anyways :
41 - used new SLF interface to massively speed up Coro::Semaphore by a factor 104 - used new SLF interface to massively speed up Coro::Semaphore by a
42 of three. 105 factor of three.
106 - used new SLF interface to speed up Coro::AIO by roughly a factor of
107 four and reduce its memory usage considerably.
108 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
109 for a nice speedup and vastly more correct behaviour. Also implement
110 a new method "sem" to get at the underlying semaphore object.
111 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
112 (in comparison) 20-40% speedup.
113 - used new SLF interface to reimplement Coro::Signal gaining
114 some unknown (because I was too lazy), but certain, speedup, and also
115 making signals reliable for the first time.
116 - used new SLF interface and other optimisations to speed up async_pool
117 by a factor of two. It also doesn't rely on perl's exception mechanism
118 to exit anymore. The overhead for terminating an async_pool, coro over
119 a normal async is now very small.
120 - sped up coroutine creation/destruction by 40%.
43 - forgot to include Coro/libcoro/README in the dist for all these years. 121 - forgot to include Coro/libcoro/README in the dist for all these years.
44 - work around a freebsd pthreads bug (manual testcancel is required as 122 - work around a freebsd pthreads bug (manual testcancel is required as
45 pthread_cond_wait isn't a cancellation point on freebsd). 123 pthread_cond_wait isn't a cancellation point on freebsd).
124 - use new rouse functions to speed up and simplify Coro::BDB.
125 - make "prefer perl native functions" work with threaded perls.
126 - condense Coro::Debug ps output, hint at v and w flags.
127 - (libcoro) lots of minor cleanups and portability improvements.

130 - fix a disastrous bug in the readline optimisation
131 introduced in 4.801.
