95.0 125.21
13 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
14 together.
15 - add some examples on how to combine other event loops with Coro in
16 Coro::AnyEvent.
17 - clarify the "not from signal handlers" section.
18
195.2 Sun Oct 4 14:54:24 CEST 2009
20 - Coro::Storable destroyed the prototypes of the functions it wrapped.
21 - export rouse_cb and rouse_wait by default now.
22 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
23 - new method $state->swap_sv.
24 - added section on "windows process emulation" to the manpage,
25 after a not-so-fruitful (nor-friendly) "discussion" with chip
26 salzenberg (discussion implies arguments, but his only arguments
27 were ad-hominems, one wonders why he started it in the first
28 place). I hope this explains it well enough for him to understand,
29 and maybe well enough for others to understand.
30 - use common::sense everywhere now.
31 - idle callbacks are no longer supported, use idle coros instead.
32 - print a thread listing when a deadlock is detected.
33
345.17 Sat Aug 22 23:09:31 CEST 2009
35 - work around a bug in the perl debugger causing crashes
36 when running under the debugger by marking _pool_handler as nodebug.
37 - speed up Coro::async considerably.
38 - try some hacks to get netbsd to work "more often" - their broken
39 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
40 - convert Coro to AE 5.0 API.
41
425.162 Tue Jul 28 04:04:03 CEST 2009
43 - perl 5.8.2 is now minimum requirement.
44 - skip t/19_handle.t on broken windows perls.
45
465.161 Wed Jul 22 04:47:38 CEST 2009
47 - Coro::AnyEvent::poll could have a different prototype when EV was
48 used as backend (analyzed by Tatsuhiko Miyagawa).
49 - Coro::AnyEvent errornously initialised the event loop when loaded,
50 not on demand.
51 - try to workaround rare */t/01_unblock.t failures.
52
535.16 Tue Jul 21 01:44:37 CEST 2009
54 - Coro::AnyEvent failed to hook into the event loop
55 when no threads had been readied between detecting
56 the event loop and actually running it.
57 - considerably speed up Coro::Select by taking avdantage
58 of AnyEvent > 4.8 and some other optimisations.
59 - implement paragraph readline mode in Coro::Handle
60 (based on patches by Zsbán Ambrus).
61 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
62 and analyzed by Yasuhiro MATSUMOTO).
63 - clarified libcoro license and copyright.
64 - someone stole my EXTRA_META!!!
65 - implement Coro::Select::patch_pp_sselect and it's brother,
66 for hardcode select overriding.
67
685.151 Mon Jul 6 05:41:57 CEST 2009
69 - backport to windows process emulation code again (patch by
70 Yasuhiro MATSUMOTO).
71 - slightly update Coro::MakeMaker.
72
735.15 Tue Jun 30 10:28:06 CEST 2009
74 - deprecate Coro::Socket, document how to get ipv6 support via
75 AnyEvent::Socket instead.
76 - implement signal->wait ($cb) interface, similar to semaphores.
77 - work around SvOK not supporting getmagic, so we have to getmagic
78 to test for undef :/ (reported by Matthias Waldorf).
79 - load Coro::AnyEvent in all modules using AnyEvent.
80 - work around perl corrupting our internal data structures,
81 reported by Tokuhiro Matsuno.
82 - enable per-coroutine real and cpu time gathering
83 (Coro::State::enable_times).
84
855.14 Wed Jun 24 01:37:48 CEST 2009
86 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
87 as this seems to have been a difficult concept (poll, sleep, idle,
88 idle_upto).
89 - add Coro::AnyEvent::readable/writable functions.
90 - clarify Coro::EV/Event/AnyEvent manpages.
91 - free per-thread global scalars in the thread calling ->cancel, to
92 avoid crashes when $_, $@ etc., are magical but some of those
93 had already been freed.
94 - "unexperimentalise" the callback interface for Coro::Semaphore.
95 - speed up ready queue management/context switching by using a linked
96 list instead of an array (~5-10%).
97 - implement "watch" command in Coro::Debug shells.
98 - for fun, implement time-slicing as an example in the manpage.
99 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
100 Coro::Event, use the normal AnyEvent handling instead of dieing
101 (the same is true for Coro::Handle).
102 - properly document Coro::EV::timed_io_once.
103 - avoid unneccessary ->cancel calls in Coro::Handle.
104 - maybe make it work on mingw32 with win32 backend
105 (based on patch by Yasuhiro Matsumoto).
106
1075.132 Fri May 29 09:00:39 CEST 2009
108 - do not keep a reference to the argument itself in
109 Coro::Semaphore::guard, as it could change later.
110 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
111 should support a prepare callback.
112
1135.131 Mon Mar 16 23:20:37 CET 2009
114 - implement and document Coro->suspend, Coro->resume.
115 - fix Coro::Select implementation to not (often) close
116 the passed file descriptors (testcase provided by pippijn).
117
1185.13 Mon Dec 15 21:51:42 CET 2008
119 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
120 - don't set diehook to C<undef> but instead to NULL, to avoid
121 spurious warnings.
122 - fix a lot of bugs in Coro::SemaphoreSet.
123 - Coro::SemaphoreSet will less often create a semaphore needlessly.
124 - add Coro::SemaphoreSet::count and wait methods.
125 - take advantage of the new Guard module.
126 - deprecate Coro::guard.
127 - try to fix the dreaded 01_unblock tests once more. I hate it when
128 testsuites need more fixing than the code they are supposed to test.
129 - croak in more cases when a required callback isn't resolvable.
130 - fix some minor issues in Coro::State->call/eval.
131 - use current coroutine context instead of a temporary one
132 when temporarily switching to another coroutine.
133 - do not call C-level on_destroy handlers during global destruction,
134 to avoid needless segfaults.
135
1365.12 Sun Dec 7 13:30:38 CET 2008
137 - add default config for MirOS, which seems to be a bug-to-bug
138 compatible fork of openbsd ("world domination by releasing
139 openbsd cvs before the openbsd folks do it" or so :).
140 - free_padlist did destroy the names pad, not good, but didn't
141 seem to bother perl - this could fix issues such as eval ""
142 inside a function called from multiple coroutines.
143 - use a different method to detect destruction time.
144 - be more careful when freeing padlists just before global
145 destruction.
146 - fixed and expanded the call/cc example.
147 - renamed _terminate to _coro_run.
148 - new method Coro::Channel->shutdown.
149 - try pthreads on openbsd <4.4 (broken sigaltstack, will
150 pthreads fare better?).
151 - be less picky about destroying "a" running coroutine.
152
1535.11 Tue Nov 25 21:49:05 CET 2008
154 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
155 working code with failed assertions, introducing more bugs than
156 it fixes, requiring elaborate workarounds :(
157
1585.1 Mon Nov 24 08:54:59 CET 2008
159 - wrote a small introductory tutorial - Coro::Intro.
160 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
161 - Coro::Select did errornously dup the file descriptors
162 and didn't work with all AnyEvent backends.
163 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
164 LWP data transfers.
165 - disassociate c contexts from coro objects - this is agruably more
166 correct, but mostly allows sharing of cctxs between coro and state
167 objects, for added memory savings and speed increases.
168 - bumped $Coro::POOL_RSS up to 32kb by default.
169 - no longer set the optype to OP_CUSTOM, as B::* understandably
170 doesn't like this very much (and we *are* a type of entersub).
171 - implement state cloning, just to prove that call/cc can be done.
172 - automatically load Coro::AnyEvent in Coro::Handle.
173 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
174 do not have this method (and don't need it either).
175 - speed up generic anyevent methods in Coro::Handle by using rouse
176 callbacks.
177 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
178 others. It also makes the debugger happier, as you can trace
179 through the idle threads now.
180 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
181 - eg/event was pretty broken.
182 - better 5.8.6 compatibility.

30 - new functions Coro::rouse_cb and Coro::rouse_wait. 203 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
204 conversion of callback-style to blocking-style.
205 - new methods $coro->schedule_to and ->cede_to, to specifically

233 - used new SLF interface and other optimisations to speed up async_pool
234 by a factor of two. It also doesn't rely on perl's exception mechanism
235 to exit anymore. The overhead for terminating an async_pool, coro over
236 a normal async is now very small.
