85.0 11 - considerably speed up Coro::Select by taking avdantage
12 of AnyEvent > 4.8 and some other optimisations.
13 - clarified libcoro license and copyright.
14 - someone stole my EXTRA_META!!!
15
165.151 Mon Jul 6 05:41:57 CEST 2009
17 - backport to windows process emulation code again (patch by
18 Yasuhiro MATSUMOTO).
19 - slightly update Coro::MakeMaker.
20
215.15 Tue Jun 30 10:28:06 CEST 2009
22 - deprecate Coro::Socket, document how to get ipv6 support via
23 AnyEvent::Socket instead.
24 - implement signal->wait ($cb) interface, similar to semaphores.
25 - work around SvOK not supporting getmagic, so we have to getmagic
26 to test for undef :/ (reported by Matthias Waldorf).
27 - load Coro::AnyEvent in all modules using AnyEvent.
28 - work around perl corrupting our internal data structures,
29 reported by Tokuhiro Matsuno.
30 - enable per-coroutine real and cpu time gathering
31 (Coro::State::enable_times).
32
335.14 Wed Jun 24 01:37:48 CEST 2009
34 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
35 as this seems to have been a difficult concept (poll, sleep, idle,
36 idle_upto).
37 - add Coro::AnyEvent::readable/writable functions.
38 - clarify Coro::EV/Event/AnyEvent manpages.
39 - free per-thread global scalars in the thread calling ->cancel, to
40 avoid crashes when $_, $@ etc., are magical but some of those
41 had already been freed.
42 - "unexperimentalise" the callback interface for Coro::Semaphore.
43 - speed up ready queue management/context switching by using a linked
44 list instead of an array (~5-10%).
45 - implement "watch" command in Coro::Debug shells.
46 - for fun, implement time-slicing as an example in the manpage.
47 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
48 Coro::Event, use the normal AnyEvent handling instead of dieing
49 (the same is true for Coro::Handle).
50 - properly document Coro::EV::timed_io_once.
51 - avoid unneccessary ->cancel calls in Coro::Handle.
52 - maybe make it work on mingw32 with win32 backend
53 (based on patch by Yasuhiro Matsumoto).
54
555.132 Fri May 29 09:00:39 CEST 2009
56 - do not keep a reference to the argument itself in
57 Coro::Semaphore::guard, as it could change later.
58 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
59 should support a prepare callback.
60
615.131 Mon Mar 16 23:20:37 CET 2009
62 - implement and document Coro->suspend, Coro->resume.
63 - fix Coro::Select implementation to not (often) close
64 the passed file descriptors (testcase provided by pippijn).
65
665.13 Mon Dec 15 21:51:42 CET 2008
67 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
68 - don't set diehook to C<undef> but instead to NULL, to avoid
69 spurious warnings.
70 - fix a lot of bugs in Coro::SemaphoreSet.
71 - Coro::SemaphoreSet will less often create a semaphore needlessly.
72 - add Coro::SemaphoreSet::count and wait methods.
73 - take advantage of the new Guard module.
74 - deprecate Coro::guard.
75 - try to fix the dreaded 01_unblock tests once more. I hate it when
76 testsuites need more fixing than the code they are supposed to test.
77 - croak in more cases when a required callback isn't resolvable.
78 - fix some minor issues in Coro::State->call/eval.
79 - use current coroutine context instead of a temporary one
80 when temporarily switching to another coroutine.
81 - do not call C-level on_destroy handlers during global destruction,
82 to avoid needless segfaults.
83
845.12 Sun Dec 7 13:30:38 CET 2008
85 - add default config for MirOS, which seems to be a bug-to-bug
86 compatible fork of openbsd ("world domination by releasing
87 openbsd cvs before the openbsd folks do it" or so :).
88 - free_padlist did destroy the names pad, not good, but didn't
89 seem to bother perl - this could fix issues such as eval ""
90 inside a function called from multiple coroutines.
91 - use a different method to detect destruction time.
92 - be more careful when freeing padlists just before global
93 destruction.
94 - fixed and expanded the call/cc example.
95 - renamed _terminate to _coro_run.
96 - new method Coro::Channel->shutdown.
97 - try pthreads on openbsd <4.4 (broken sigaltstack, will
98 pthreads fare better?).
99 - be less picky about destroying "a" running coroutine.
100
1015.11 Tue Nov 25 21:49:05 CET 2008
102 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
103 working code with failed assertions, introducing more bugs than
104 it fixes, requiring elaborate workarounds :(
105
1065.1 Mon Nov 24 08:54:59 CET 2008
107 - wrote a small introductory tutorial - Coro::Intro.
108 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
109 - Coro::Select did errornously dup the file descriptors
110 and didn't work with all AnyEvent backends.
111 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
112 LWP data transfers.
113 - disassociate c contexts from coro objects - this is agruably more
114 correct, but mostly allows sharing of cctxs between coro and state
115 objects, for added memory savings and speed increases.
116 - bumped $Coro::POOL_RSS up to 32kb by default.
117 - no longer set the optype to OP_CUSTOM, as B::* understandably
118 doesn't like this very much (and we *are* a type of entersub).
119 - implement state cloning, just to prove that call/cc can be done.
120 - automatically load Coro::AnyEvent in Coro::Handle.
121 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
122 do not have this method (and don't need it either).
123 - speed up generic anyevent methods in Coro::Handle by using rouse
124 callbacks.
125 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
126 others. It also makes the debugger happier, as you can trace
127 through the idle threads now.
128 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
129 - eg/event was pretty broken.
130 - better 5.8.6 compatibility.
131
1325.0 Thu Nov 20 10:35:05 CET 2008
133 - NEW ARCHITECTURE: use the latest 4.x version if you experience
134 stability issues.
135 - bump API version to 7 - all dependents must be recompiled.
136 - removed timed_* functions - they were not being used anyways
137 and should be replaced by a more generic mechanism -
138 and were annoying to support anyways :)
139 - removed SemaphoreSet's waiter method - use sem method instead.
140 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
141 - async_pool did free a scalar value twice
142 ("Attempt to unreference...").
143 - fix a longstanding bug where calling terminate on a coro that
144 was waiting for a semaphore that was just becoming available
145 would cause a deadlock (semaphore would get into a state where
146 it was available but waiters were still blocked).
147 - calling throw on a coroutine that is waiting for a semaphore will
148 no longer make it acquire the semaphore (and thus leak a count).
149 - perl's process emulation is now not even theoretically supported
150 anymore.
151 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
152 conversion of callback-style to blocking-style.
153 - new methods $coro->schedule_to and ->cede_to, to specifically
154 schedule or cede to a specific coroutine.
155 - new function Coro::Semaphore::wait.
156 - use named constants in Coro::Channel (Richard Hundt).
157 - directly patch the entersub opcode calling SLF functions (cede,
158 transfer and so on). this does speed up context switching, but
159 more importanly, it frees us from the hardcoded behaviour of
160 entersub, so we might actually be able to return something from
161 those functions and atcually create new ones.
162 - take advantage of __builtin_frame_address on gcc.
163 - expose THX in coroapi (not sure whether this was a wise decision,
164 as "threaded" perls are running at half speed anyways).
165 - implement execute_slf (schedule-like-function) interface that makes
166 it possible to implement schedule-like-functions in XS.
167 - use new SLF interface to massively speed up Coro::EV by roughly a
168 factor of two.
169 - used new SLF interface to massively speed up Coro::Semaphore by a
170 factor of three.
171 - used new SLF interface to speed up Coro::AIO by roughly a factor of
172 four and reduce its memory usage considerably.
173 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
174 for a nice speedup and vastly more correct behaviour. Also implement
175 a new method "sem" to get at the underlying semaphore object.
176 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
177 (in comparison) 20-40% speedup.
178 - used new SLF interface to reimplement Coro::Signal gaining
179 some unknown (because I was too lazy), but certain, speedup, and also
180 making signals reliable for the first time.
181 - used new SLF interface and other optimisations to speed up async_pool
182 by a factor of two. It also doesn't rely on perl's exception mechanism
183 to exit anymore. The overhead for terminating an async_pool, coro over
184 a normal async is now very small.
185 - sped up coroutine creation/destruction by 40%.
186 - forgot to include Coro/libcoro/README in the dist for all these years.
187 - work around a freebsd pthreads bug (manual testcancel is required as
188 pthread_cond_wait isn't a cancellation point on freebsd).
189 - use new rouse functions to speed up and simplify Coro::BDB.
190 - make "prefer perl native functions" work with threaded perls.
191 - condense Coro::Debug ps output, hint at v and w flags.
192 - (libcoro) lots of minor cleanups and portability improvements.
193
1944.914 Wed Nov 19 12:54:18 CET 2008
195 - fix a disastrous bug in the readline optimisation
196 introduced in 4.801.
197
1984.913 Sat Nov 15 07:58:28 CET 2008
199 - async_pool did free a scalar value twice
200 ("Attempt to unreference...").
201
2024.912 Thu Nov 13 18:31:23 CET 2008
203 - minor cleanups.
204 - use much larger stacks on linux and perl < 5.8.8.
205 - Coro::Debug::new_unix_server did not unlink the socket
206 when destroyed.
207
2084.911 Tue Nov 11 04:26:17 CET 2008
209 - "port" to threaded perls.
210
2114.91 Mon Nov 10 05:36:38 CET 2008
212 - the ->throw exception object no longer leaks.
213 - creating a new cctx leaked a scopestack entry (memleak).
214 - new coroutines didn't get created with a zero flags field
215 (unknown impact).
216 - calling ->throw on a not-yet-started coroutine should now work
217 instead of being ignored.
218 - ->throw is now supported on Coro::State objects.
219 - clean up cctx creation code a bit.
220 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
