115.0 14 - Coro::Storable destroyed the prototypes of the functions it wrapped.
12 - NEW ARCHITECTURE: use 4.912 for the stable version. 15 - export rouse_cb and rouse_wait by default now.
16 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
17 - new method $state->swap_sv.
18 - added section on "windows process emulation" to the manpage,
19 after a not-so-fruitful (nor-friendly) "discussion" with chip
20 salzenberg (discussion implies arguments, but his only arguments
21 were ad-hominems, one wonders why he started it in the first
22 place). I hope this explains it well enough for him to understand,
23 and maybe well enough for others to understand.
24 - use common::sense everywhere now.
25 - idle callbacks are no longer supported, use idle coros instead.
26 - print a thread listing when a deadlock is detected.
27
285.17 Sat Aug 22 23:09:31 CEST 2009
29 - work around a bug in the perl debugger causing crashes
30 when running under the debugger by marking _pool_handler as nodebug.
31 - speed up Coro::async considerably.
32 - try some hacks to get netbsd to work "more often" - their broken
33 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
34 - convert Coro to AE 5.0 API.
35
365.162 Tue Jul 28 04:04:03 CEST 2009
37 - perl 5.8.2 is now minimum requirement.
38 - skip t/19_handle.t on broken windows perls.
39
405.161 Wed Jul 22 04:47:38 CEST 2009
41 - Coro::AnyEvent::poll could have a different prototype when EV was
42 used as backend (analyzed by Tatsuhiko Miyagawa).
43 - Coro::AnyEvent errornously initialised the event loop when loaded,
44 not on demand.
45 - try to workaround rare */t/01_unblock.t failures.
46
475.16 Tue Jul 21 01:44:37 CEST 2009
48 - Coro::AnyEvent failed to hook into the event loop
49 when no threads had been readied between detecting
50 the event loop and actually running it.
51 - considerably speed up Coro::Select by taking avdantage
52 of AnyEvent > 4.8 and some other optimisations.
53 - implement paragraph readline mode in Coro::Handle
54 (based on patches by Zsbán Ambrus).
55 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
56 and analyzed by Yasuhiro MATSUMOTO).
57 - clarified libcoro license and copyright.
58 - someone stole my EXTRA_META!!!
59 - implement Coro::Select::patch_pp_sselect and it's brother,
60 for hardcode select overriding.
61
625.151 Mon Jul 6 05:41:57 CEST 2009
63 - backport to windows process emulation code again (patch by
64 Yasuhiro MATSUMOTO).
65 - slightly update Coro::MakeMaker.
66
675.15 Tue Jun 30 10:28:06 CEST 2009
68 - deprecate Coro::Socket, document how to get ipv6 support via
69 AnyEvent::Socket instead.
70 - implement signal->wait ($cb) interface, similar to semaphores.
71 - work around SvOK not supporting getmagic, so we have to getmagic
72 to test for undef :/ (reported by Matthias Waldorf).
73 - load Coro::AnyEvent in all modules using AnyEvent.
74 - work around perl corrupting our internal data structures,
75 reported by Tokuhiro Matsuno.
76 - enable per-coroutine real and cpu time gathering
77 (Coro::State::enable_times).
78
795.14 Wed Jun 24 01:37:48 CEST 2009
80 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
81 as this seems to have been a difficult concept (poll, sleep, idle,
82 idle_upto).
83 - add Coro::AnyEvent::readable/writable functions.
84 - clarify Coro::EV/Event/AnyEvent manpages.
85 - free per-thread global scalars in the thread calling ->cancel, to
86 avoid crashes when $_, $@ etc., are magical but some of those
87 had already been freed.
88 - "unexperimentalise" the callback interface for Coro::Semaphore.
89 - speed up ready queue management/context switching by using a linked
90 list instead of an array (~5-10%).
91 - implement "watch" command in Coro::Debug shells.
92 - for fun, implement time-slicing as an example in the manpage.
93 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
94 Coro::Event, use the normal AnyEvent handling instead of dieing
95 (the same is true for Coro::Handle).
96 - properly document Coro::EV::timed_io_once.
97 - avoid unneccessary ->cancel calls in Coro::Handle.
98 - maybe make it work on mingw32 with win32 backend
99 (based on patch by Yasuhiro Matsumoto).
100
1015.132 Fri May 29 09:00:39 CEST 2009
102 - do not keep a reference to the argument itself in
103 Coro::Semaphore::guard, as it could change later.
104 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
105 should support a prepare callback.
106
1075.131 Mon Mar 16 23:20:37 CET 2009
108 - implement and document Coro->suspend, Coro->resume.
109 - fix Coro::Select implementation to not (often) close
110 the passed file descriptors (testcase provided by pippijn).
111
1125.13 Mon Dec 15 21:51:42 CET 2008
113 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
114 - don't set diehook to C<undef> but instead to NULL, to avoid
115 spurious warnings.
116 - fix a lot of bugs in Coro::SemaphoreSet.
117 - Coro::SemaphoreSet will less often create a semaphore needlessly.
118 - add Coro::SemaphoreSet::count and wait methods.
119 - take advantage of the new Guard module.
120 - deprecate Coro::guard.
121 - try to fix the dreaded 01_unblock tests once more. I hate it when
122 testsuites need more fixing than the code they are supposed to test.
123 - croak in more cases when a required callback isn't resolvable.
124 - fix some minor issues in Coro::State->call/eval.
125 - use current coroutine context instead of a temporary one
126 when temporarily switching to another coroutine.
127 - do not call C-level on_destroy handlers during global destruction,
128 to avoid needless segfaults.
129
1305.12 Sun Dec 7 13:30:38 CET 2008
131 - add default config for MirOS, which seems to be a bug-to-bug
132 compatible fork of openbsd ("world domination by releasing
133 openbsd cvs before the openbsd folks do it" or so :).
134 - free_padlist did destroy the names pad, not good, but didn't
135 seem to bother perl - this could fix issues such as eval ""
136 inside a function called from multiple coroutines.
137 - use a different method to detect destruction time.
138 - be more careful when freeing padlists just before global
139 destruction.
140 - fixed and expanded the call/cc example.
141 - renamed _terminate to _coro_run.
142 - new method Coro::Channel->shutdown.
143 - try pthreads on openbsd <4.4 (broken sigaltstack, will
144 pthreads fare better?).
145 - be less picky about destroying "a" running coroutine.
146
1475.11 Tue Nov 25 21:49:05 CET 2008
148 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
149 working code with failed assertions, introducing more bugs than
150 it fixes, requiring elaborate workarounds :(
151
1525.1 Mon Nov 24 08:54:59 CET 2008
153 - wrote a small introductory tutorial - Coro::Intro.
154 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
155 - Coro::Select did errornously dup the file descriptors
156 and didn't work with all AnyEvent backends.
157 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
158 LWP data transfers.
159 - disassociate c contexts from coro objects - this is agruably more
160 correct, but mostly allows sharing of cctxs between coro and state
161 objects, for added memory savings and speed increases.
162 - bumped $Coro::POOL_RSS up to 32kb by default.
163 - no longer set the optype to OP_CUSTOM, as B::* understandably
164 doesn't like this very much (and we *are* a type of entersub).
165 - implement state cloning, just to prove that call/cc can be done.
166 - automatically load Coro::AnyEvent in Coro::Handle.
167 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
168 do not have this method (and don't need it either).
169 - speed up generic anyevent methods in Coro::Handle by using rouse
170 callbacks.
171 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
172 others. It also makes the debugger happier, as you can trace
173 through the idle threads now.
174 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
175 - eg/event was pretty broken.
176 - better 5.8.6 compatibility.
177
1785.0 Thu Nov 20 10:35:05 CET 2008
179 - NEW ARCHITECTURE: use the latest 4.x version if you experience
180 stability issues.
13 - bump API version to 7 - all dependents must be recompiled. 181 - bump API version to 7 - all dependents must be recompiled.
182 - removed timed_* functions - they were not being used anyways
183 and should be replaced by a more generic mechanism -
184 and were annoying to support anyways :)
185 - removed SemaphoreSet's waiter method - use sem method instead.
14 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 186 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
15 - async_pool did free a scalar value twice 187 - async_pool did free a scalar value twice
16 ("Attempt to unreference..."). 188 ("Attempt to unreference...").
17 - fix a longstanding bug where calling terminate on a coro that 189 - fix a longstanding bug where calling terminate on a coro that
18 was waiting for a semaphore that was just becoming available 190 was waiting for a semaphore that was just becoming available
19 would cause a deadlock (semaphore would get into a state where 191 would cause a deadlock (semaphore would get into a state where
20 it was available but waiters were waiting(. 192 it was available but waiters were still blocked).
193 - calling throw on a coroutine that is waiting for a semaphore will
194 no longer make it acquire the semaphore (and thus leak a count).
21 - perl's process emulation is now not even theoretically supported 195 - perl's process emulation is now not even theoretically supported
22 anymore. 196 anymore.
197 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
198 conversion of callback-style to blocking-style.
199 - new methods $coro->schedule_to and ->cede_to, to specifically
200 schedule or cede to a specific coroutine.
201 - new function Coro::Semaphore::wait.
202 - use named constants in Coro::Channel (Richard Hundt).
23 - directly patch the entersub opcode calling SLF functions (cede, 203 - directly patch the entersub opcode calling SLF functions (cede,
24 transfer and so on). this does speed up context switching, but 204 transfer and so on). this does speed up context switching, but
25 more importanly, it frees us from the hardcoded behaviour of 205 more importanly, it frees us from the hardcoded behaviour of
26 entersub, so we might actually be able to return something from 206 entersub, so we might actually be able to return something from
27 those functions and atcually create new ones. 207 those functions and atcually create new ones.
28 - take advantage of __builtin_frame_address on gcc. 208 - take advantage of __builtin_frame_address on gcc.
29 - expose THX in coroapi (not sure whether this was a wise decision, 209 - expose THX in coroapi (not sure whether this was a wise decision,
30 as "threaded" perls are running at half speed anyways). 210 as "threaded" perls are running at half speed anyways).
31 - implement execute_slf (schedule-like-function) interface that makes 211 - implement execute_slf (schedule-like-function) interface that makes
32 it possible to implement schedule-like-functions in XS. 212 it possible to implement schedule-like-functions in XS.
33 - use new SLF interface to massively speed up Coro::EV by roughly a factor 213 - use new SLF interface to massively speed up Coro::EV by roughly a
34 of two. 214 factor of two.
35 - removed timed_down and timed_guard functions - they were not being used
36 anyways and should be replaced by a more generic mechanism - and were
37 annoying to support anyways :
38 - used new SLF interface to massively speed up Coro::Semaphore by a factor 215 - used new SLF interface to massively speed up Coro::Semaphore by a
39 of three. 216 factor of three.
217 - used new SLF interface to speed up Coro::AIO by roughly a factor of
218 four and reduce its memory usage considerably.
219 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
220 for a nice speedup and vastly more correct behaviour. Also implement
221 a new method "sem" to get at the underlying semaphore object.
222 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
223 (in comparison) 20-40% speedup.
224 - used new SLF interface to reimplement Coro::Signal gaining
225 some unknown (because I was too lazy), but certain, speedup, and also
226 making signals reliable for the first time.
227 - used new SLF interface and other optimisations to speed up async_pool
228 by a factor of two. It also doesn't rely on perl's exception mechanism
229 to exit anymore. The overhead for terminating an async_pool, coro over
230 a normal async is now very small.
231 - sped up coroutine creation/destruction by 40%.
40 - forgot to include Coro/libcoro/README in the dist for all these years. 232 - forgot to include Coro/libcoro/README in the dist for all these years.
41 - work around a freebsd pthreads bug (manual testcancel is required as 233 - work around a freebsd pthreads bug (manual testcancel is required as
42 pthread_cond_wait isn't a cancellation point on freebsd). 234 pthread_cond_wait isn't a cancellation point on freebsd).
235 - use new rouse functions to speed up and simplify Coro::BDB.
236 - make "prefer perl native functions" work with threaded perls.
237 - condense Coro::Debug ps output, hint at v and w flags.
238 - (libcoro) lots of minor cleanups and portability improvements.
239
2404.914 Wed Nov 19 12:54:18 CET 2008
241 - fix a disastrous bug in the readline optimisation
242 introduced in 4.801.
