135.0 145.22 Wed Apr 14 03:55:35 CEST 2010
15 - correctly return udnef on errors in Coro::Handle::read/write
16 (testcase by Marc Mims).
17 - convert Coro::Util into a "perl compatibility wrapper" - the functions
18 are less useful now, but are drop-in replacements for existing
19 functions, listing better alternatives in the documentation. This also
20 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
21 with Coro::Util::inet_aton.
22 - do not override $Coro::idle unconditionally in Coro.pm, as other
23 modules could have provided their own idle coro already
24 (for exmaple, Coro::AnyEvent).
25 - fix Coro::Util::gethost* functions.
26 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
27
285.21 Wed Dec 16 07:19:51 CET 2009
29 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
30 together.
31 - add some examples on how to combine other event loops with Coro in
32 Coro::AnyEvent, and how to run it (and not to block). Seems to be
33 the most common source of confusion.
34 - try to catch people naively blocking in an event callback.
35 - work around the perl filehandle bug issue in conjunction with
36 older common::sense (as indirectly pointed out by ZSystem).
37 - clarify the "not from signal handlers" section.
38
395.2 Sun Oct 4 14:54:24 CEST 2009
40 - Coro::Storable destroyed the prototypes of the functions it wrapped.
41 - export rouse_cb and rouse_wait by default now.
42 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
43 - new method $state->swap_sv.
44 - added section on "windows process emulation" to the manpage,
45 after a not-so-fruitful (nor-friendly) "discussion" with chip
46 salzenberg (discussion implies arguments, but his only arguments
47 were ad-hominems, one wonders why he started it in the first
48 place). I hope this explains it well enough for him to understand,
49 and maybe well enough for others to understand.
50 - use common::sense everywhere now.
51 - idle callbacks are no longer supported, use idle coros instead.
52 - print a thread listing when a deadlock is detected.
53
545.17 Sat Aug 22 23:09:31 CEST 2009
55 - work around a bug in the perl debugger causing crashes
56 when running under the debugger by marking _pool_handler as nodebug.
57 - speed up Coro::async considerably.
58 - try some hacks to get netbsd to work "more often" - their broken
59 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
60 - convert Coro to AE 5.0 API.
61
625.162 Tue Jul 28 04:04:03 CEST 2009
63 - perl 5.8.2 is now minimum requirement.
64 - skip t/19_handle.t on broken windows perls.
65
665.161 Wed Jul 22 04:47:38 CEST 2009
67 - Coro::AnyEvent::poll could have a different prototype when EV was
68 used as backend (analyzed by Tatsuhiko Miyagawa).
69 - Coro::AnyEvent errornously initialised the event loop when loaded,
70 not on demand.
71 - try to workaround rare */t/01_unblock.t failures.
72
735.16 Tue Jul 21 01:44:37 CEST 2009
74 - Coro::AnyEvent failed to hook into the event loop
75 when no threads had been readied between detecting
76 the event loop and actually running it.
77 - considerably speed up Coro::Select by taking avdantage
78 of AnyEvent > 4.8 and some other optimisations.
79 - implement paragraph readline mode in Coro::Handle
80 (based on patches by Zsbán Ambrus).
81 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
82 and analyzed by Yasuhiro MATSUMOTO).
83 - clarified libcoro license and copyright.
84 - someone stole my EXTRA_META!!!
85 - implement Coro::Select::patch_pp_sselect and it's brother,
86 for hardcode select overriding.
87
885.151 Mon Jul 6 05:41:57 CEST 2009
89 - backport to windows process emulation code again (patch by
90 Yasuhiro MATSUMOTO).
91 - slightly update Coro::MakeMaker.
92
935.15 Tue Jun 30 10:28:06 CEST 2009
94 - deprecate Coro::Socket, document how to get ipv6 support via
95 AnyEvent::Socket instead.
96 - implement signal->wait ($cb) interface, similar to semaphores.
97 - work around SvOK not supporting getmagic, so we have to getmagic
98 to test for undef :/ (reported by Matthias Waldorf).
99 - load Coro::AnyEvent in all modules using AnyEvent.
100 - work around perl corrupting our internal data structures,
101 reported by Tokuhiro Matsuno.
102 - enable per-coroutine real and cpu time gathering
103 (Coro::State::enable_times).
104
1055.14 Wed Jun 24 01:37:48 CEST 2009
106 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
107 as this seems to have been a difficult concept (poll, sleep, idle,
108 idle_upto).
109 - add Coro::AnyEvent::readable/writable functions.
110 - clarify Coro::EV/Event/AnyEvent manpages.
111 - free per-thread global scalars in the thread calling ->cancel, to
112 avoid crashes when $_, $@ etc., are magical but some of those
113 had already been freed.
114 - "unexperimentalise" the callback interface for Coro::Semaphore.
115 - speed up ready queue management/context switching by using a linked
116 list instead of an array (~5-10%).
117 - implement "watch" command in Coro::Debug shells.
118 - for fun, implement time-slicing as an example in the manpage.
119 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
120 Coro::Event, use the normal AnyEvent handling instead of dieing
121 (the same is true for Coro::Handle).
122 - properly document Coro::EV::timed_io_once.
123 - avoid unneccessary ->cancel calls in Coro::Handle.
124 - maybe make it work on mingw32 with win32 backend
125 (based on patch by Yasuhiro Matsumoto).
126
1275.132 Fri May 29 09:00:39 CEST 2009
128 - do not keep a reference to the argument itself in
129 Coro::Semaphore::guard, as it could change later.
130 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
131 should support a prepare callback.
132
1335.131 Mon Mar 16 23:20:37 CET 2009
134 - implement and document Coro->suspend, Coro->resume.
135 - fix Coro::Select implementation to not (often) close
136 the passed file descriptors (testcase provided by pippijn).
137
1385.13 Mon Dec 15 21:51:42 CET 2008
139 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
140 - don't set diehook to C<undef> but instead to NULL, to avoid
141 spurious warnings.
142 - fix a lot of bugs in Coro::SemaphoreSet.
143 - Coro::SemaphoreSet will less often create a semaphore needlessly.
144 - add Coro::SemaphoreSet::count and wait methods.
145 - take advantage of the new Guard module.
146 - deprecate Coro::guard.
147 - try to fix the dreaded 01_unblock tests once more. I hate it when
148 testsuites need more fixing than the code they are supposed to test.
149 - croak in more cases when a required callback isn't resolvable.
150 - fix some minor issues in Coro::State->call/eval.
151 - use current coroutine context instead of a temporary one
152 when temporarily switching to another coroutine.
153 - do not call C-level on_destroy handlers during global destruction,
154 to avoid needless segfaults.
155
1565.12 Sun Dec 7 13:30:38 CET 2008
157 - add default config for MirOS, which seems to be a bug-to-bug
158 compatible fork of openbsd ("world domination by releasing
159 openbsd cvs before the openbsd folks do it" or so :).
160 - free_padlist did destroy the names pad, not good, but didn't
161 seem to bother perl - this could fix issues such as eval ""
162 inside a function called from multiple coroutines.
163 - use a different method to detect destruction time.
164 - be more careful when freeing padlists just before global
165 destruction.
166 - fixed and expanded the call/cc example.
167 - renamed _terminate to _coro_run.
168 - new method Coro::Channel->shutdown.
169 - try pthreads on openbsd <4.4 (broken sigaltstack, will
170 pthreads fare better?).
171 - be less picky about destroying "a" running coroutine.
172
1735.11 Tue Nov 25 21:49:05 CET 2008
174 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
175 working code with failed assertions, introducing more bugs than
176 it fixes, requiring elaborate workarounds :(
177
1785.1 Mon Nov 24 08:54:59 CET 2008
179 - wrote a small introductory tutorial - Coro::Intro.
180 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
181 - Coro::Select did errornously dup the file descriptors
182 and didn't work with all AnyEvent backends.
183 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
184 LWP data transfers.
185 - disassociate c contexts from coro objects - this is agruably more
186 correct, but mostly allows sharing of cctxs between coro and state
187 objects, for added memory savings and speed increases.
188 - bumped $Coro::POOL_RSS up to 32kb by default.
189 - no longer set the optype to OP_CUSTOM, as B::* understandably
190 doesn't like this very much (and we *are* a type of entersub).
191 - implement state cloning, just to prove that call/cc can be done.
192 - automatically load Coro::AnyEvent in Coro::Handle.
193 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
194 do not have this method (and don't need it either).
195 - speed up generic anyevent methods in Coro::Handle by using rouse
196 callbacks.
197 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
198 others. It also makes the debugger happier, as you can trace
199 through the idle threads now.
200 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
201 - eg/event was pretty broken.
202 - better 5.8.6 compatibility.
203
2045.0 Thu Nov 20 10:35:05 CET 2008
14 - NEW ARCHITECTURE: use the latest 4.x version if you experience 205 - NEW ARCHITECTURE: use the latest 4.x version if you experience
15 stability issues. 206 stability issues.
16 - bump API version to 7 - all dependents must be recompiled. 207 - bump API version to 7 - all dependents must be recompiled.
208 - removed timed_* functions - they were not being used anyways
209 and should be replaced by a more generic mechanism -
210 and were annoying to support anyways :)
211 - removed SemaphoreSet's waiter method - use sem method instead.
17 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 212 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
18 - async_pool did free a scalar value twice 213 - async_pool did free a scalar value twice
19 ("Attempt to unreference..."). 214 ("Attempt to unreference...").
20 - fix a longstanding bug where calling terminate on a coro that 215 - fix a longstanding bug where calling terminate on a coro that
21 was waiting for a semaphore that was just becoming available 216 was waiting for a semaphore that was just becoming available
22 would cause a deadlock (semaphore would get into a state where 217 would cause a deadlock (semaphore would get into a state where
23 it was available but waiters were waiting(. 218 it was available but waiters were still blocked).
24 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 219 - calling throw on a coroutine that is waiting for a semaphore will
220 no longer make it acquire the semaphore (and thus leak a count).
25 - perl's process emulation is now not even theoretically supported 221 - perl's process emulation is now not even theoretically supported
26 anymore. 222 anymore.
223 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
224 conversion of callback-style to blocking-style.
225 - new methods $coro->schedule_to and ->cede_to, to specifically
226 schedule or cede to a specific coroutine.
227 - new function Coro::Semaphore::wait.
228 - use named constants in Coro::Channel (Richard Hundt).
27 - directly patch the entersub opcode calling SLF functions (cede, 229 - directly patch the entersub opcode calling SLF functions (cede,
28 transfer and so on). this does speed up context switching, but 230 transfer and so on). this does speed up context switching, but
29 more importanly, it frees us from the hardcoded behaviour of 231 more importanly, it frees us from the hardcoded behaviour of
30 entersub, so we might actually be able to return something from 232 entersub, so we might actually be able to return something from

36 it possible to implement schedule-like-functions in XS. 238 it possible to implement schedule-like-functions in XS.
37 - use new SLF interface to massively speed up Coro::EV by roughly a 239 - use new SLF interface to massively speed up Coro::EV by roughly a
38 factor of two. 240 factor of two.
39 - removed timed_down and timed_guard functions - they were not being
40 used anyways and should be replaced by a more generic mechanism -
41 and were annoying to support anyways :)
42 - used new SLF interface to massively speed up Coro::Semaphore by a 241 - used new SLF interface to massively speed up Coro::Semaphore by a
43 factor of three. 242 factor of three.
44 - used new SLF interface to speed up Coro::AIO by roughly a factor of 243 - used new SLF interface to speed up Coro::AIO by roughly a factor of
45 four and reduce its memory usage considerably. 244 four and reduce its memory usage considerably.
245 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
246 for a nice speedup and vastly more correct behaviour. Also implement
247 a new method "sem" to get at the underlying semaphore object.
248 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
249 (in comparison) 20-40% speedup.
250 - used new SLF interface to reimplement Coro::Signal gaining
251 some unknown (because I was too lazy), but certain, speedup, and also
252 making signals reliable for the first time.
253 - used new SLF interface and other optimisations to speed up async_pool
254 by a factor of two. It also doesn't rely on perl's exception mechanism
255 to exit anymore. The overhead for terminating an async_pool, coro over
256 a normal async is now very small.
257 - sped up coroutine creation/destruction by 40%.
46 - forgot to include Coro/libcoro/README in the dist for all these years. 258 - forgot to include Coro/libcoro/README in the dist for all these years.
47 - work around a freebsd pthreads bug (manual testcancel is required as 259 - work around a freebsd pthreads bug (manual testcancel is required as
48 pthread_cond_wait isn't a cancellation point on freebsd). 260 pthread_cond_wait isn't a cancellation point on freebsd).
261 - use new rouse functions to speed up and simplify Coro::BDB.
262 - make "prefer perl native functions" work with threaded perls.
263 - condense Coro::Debug ps output, hint at v and w flags.
264 - (libcoro) lots of minor cleanups and portability improvements.
265
2664.914 Wed Nov 19 12:54:18 CET 2008
267 - fix a disastrous bug in the readline optimisation
268 introduced in 4.801.
