135.0 14 - implement and document Coro->suspend, Coro->resume.
14 - NEW ARCHITECTURE: use 4.912 for the stable version. 15 - fix Coro::Select implementation to not (often) close
16 the passed file descriptors (testcase provided by pippijn).
17
185.13 Mon Dec 15 21:51:42 CET 2008
19 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
20 - don't set diehook to C<undef> but instead to NULL, to avoid
21 spurious warnings.
22 - fix a lot of bugs in Coro::SemaphoreSet.
23 - Coro::SemaphoreSet will less often create a semaphore needlessly.
24 - add Coro::SemaphoreSet::count and wait methods.
25 - take advantage of the new Guard module.
26 - deprecate Coro::guard.
27 - try to fix the dreaded 01_unblock tests once more. I hate it when
28 testsuites need more fixing than the code they are supposed to test.
29 - croak in more cases when a required callback isn't resolvable.
30 - fix some minor issues in Coro::State->call/eval.
31 - use current coroutine context instead of a temporary one
32 when temporarily switching to another coroutine.
33 - do not call C-level on_destroy handlers during global destruction,
34 to avoid needless segfaults.
35
365.12 Sun Dec 7 13:30:38 CET 2008
37 - add default config for MirOS, which seems to be a bug-to-bug
38 compatible fork of openbsd ("world domination by releasing
39 openbsd cvs before the openbsd folks do it" or so :).
40 - free_padlist did destroy the names pad, not good, but didn't
41 seem to bother perl - this could fix issues such as eval ""
42 inside a function called from multiple coroutines.
43 - use a different method to detect destruction time.
44 - be more careful when freeing padlists just before global
45 destruction.
46 - fixed and expanded the call/cc example.
47 - renamed _terminate to _coro_run.
48 - new method Coro::Channel->shutdown.
49 - try pthreads on openbsd <4.4 (broken sigaltstack, will
50 pthreads fare better?).
51 - be less picky about destroying "a" running coroutine.
52
535.11 Tue Nov 25 21:49:05 CET 2008
54 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
55 working code with failed assertions, introducing more bugs than
56 it fixes, requiring elaborate workarounds :(
57
585.1 Mon Nov 24 08:54:59 CET 2008
59 - wrote a small introductory tutorial - Coro::Intro.
60 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
61 - Coro::Select did errornously dup the file descriptors
62 and didn't work with all AnyEvent backends.
63 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
64 LWP data transfers.
65 - disassociate c contexts from coro objects - this is agruably more
66 correct, but mostly allows sharing of cctxs between coro and state
67 objects, for added memory savings and speed increases.
68 - bumped $Coro::POOL_RSS up to 32kb by default.
69 - no longer set the optype to OP_CUSTOM, as B::* understandably
70 doesn't like this very much (and we *are* a type of entersub).
71 - implement state cloning, just to prove that call/cc can be done.
72 - automatically load Coro::AnyEvent in Coro::Handle.
73 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
74 do not have this method (and don't need it either).
75 - speed up generic anyevent methods in Coro::Handle by using rouse
76 callbacks.
77 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
78 others. It also makes the debugger happier, as you can trace
79 through the idle threads now.
80 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
81 - eg/event was pretty broken.
82 - better 5.8.6 compatibility.
83
845.0 Thu Nov 20 10:35:05 CET 2008
85 - NEW ARCHITECTURE: use the latest 4.x version if you experience
86 stability issues.
15 - bump API version to 7 - all dependents must be recompiled. 87 - bump API version to 7 - all dependents must be recompiled.
88 - removed timed_* functions - they were not being used anyways
89 and should be replaced by a more generic mechanism -
90 and were annoying to support anyways :)
91 - removed SemaphoreSet's waiter method - use sem method instead.
16 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 92 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
17 - async_pool did free a scalar value twice 93 - async_pool did free a scalar value twice
18 ("Attempt to unreference..."). 94 ("Attempt to unreference...").
19 - fix a longstanding bug where calling terminate on a coro that 95 - fix a longstanding bug where calling terminate on a coro that
20 was waiting for a semaphore that was just becoming available 96 was waiting for a semaphore that was just becoming available
21 would cause a deadlock (semaphore would get into a state where 97 would cause a deadlock (semaphore would get into a state where
22 it was available but waiters were waiting(. 98 it was available but waiters were still blocked).
23 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 99 - calling throw on a coroutine that is waiting for a semaphore will
100 no longer make it acquire the semaphore (and thus leak a count).
24 - perl's process emulation is now not even theoretically supported 101 - perl's process emulation is now not even theoretically supported
25 anymore. 102 anymore.
103 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
104 conversion of callback-style to blocking-style.
105 - new methods $coro->schedule_to and ->cede_to, to specifically
106 schedule or cede to a specific coroutine.
107 - new function Coro::Semaphore::wait.
108 - use named constants in Coro::Channel (Richard Hundt).
26 - directly patch the entersub opcode calling SLF functions (cede, 109 - directly patch the entersub opcode calling SLF functions (cede,
27 transfer and so on). this does speed up context switching, but 110 transfer and so on). this does speed up context switching, but
28 more importanly, it frees us from the hardcoded behaviour of 111 more importanly, it frees us from the hardcoded behaviour of
29 entersub, so we might actually be able to return something from 112 entersub, so we might actually be able to return something from
30 those functions and atcually create new ones. 113 those functions and atcually create new ones.
31 - take advantage of __builtin_frame_address on gcc. 114 - take advantage of __builtin_frame_address on gcc.
32 - expose THX in coroapi (not sure whether this was a wise decision, 115 - expose THX in coroapi (not sure whether this was a wise decision,
33 as "threaded" perls are running at half speed anyways). 116 as "threaded" perls are running at half speed anyways).
34 - implement execute_slf (schedule-like-function) interface that makes 117 - implement execute_slf (schedule-like-function) interface that makes
35 it possible to implement schedule-like-functions in XS. 118 it possible to implement schedule-like-functions in XS.
36 - use new SLF interface to massively speed up Coro::EV by roughly a factor 119 - use new SLF interface to massively speed up Coro::EV by roughly a
37 of two. 120 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 121 - used new SLF interface to massively speed up Coro::Semaphore by a
42 of three. 122 factor of three.
123 - used new SLF interface to speed up Coro::AIO by roughly a factor of
124 four and reduce its memory usage considerably.
125 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
126 for a nice speedup and vastly more correct behaviour. Also implement
127 a new method "sem" to get at the underlying semaphore object.
128 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
129 (in comparison) 20-40% speedup.
130 - used new SLF interface to reimplement Coro::Signal gaining
131 some unknown (because I was too lazy), but certain, speedup, and also
132 making signals reliable for the first time.
133 - used new SLF interface and other optimisations to speed up async_pool
134 by a factor of two. It also doesn't rely on perl's exception mechanism
135 to exit anymore. The overhead for terminating an async_pool, coro over
136 a normal async is now very small.
137 - sped up coroutine creation/destruction by 40%.
43 - forgot to include Coro/libcoro/README in the dist for all these years. 138 - 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 139 - work around a freebsd pthreads bug (manual testcancel is required as
45 pthread_cond_wait isn't a cancellation point on freebsd). 140 pthread_cond_wait isn't a cancellation point on freebsd).
141 - use new rouse functions to speed up and simplify Coro::BDB.
142 - make "prefer perl native functions" work with threaded perls.
143 - condense Coro::Debug ps output, hint at v and w flags.
144 - (libcoro) lots of minor cleanups and portability improvements.

1464.914 Wed Nov 19 12:54:18 CET 2008
147 - fix a disastrous bug in the readline optimisation
148 introduced in 4.801.
