12 - Coro::Storable destroyed the prototypes of the functions it wrapped.
13 - export rouse_cb and rouse_wait by default now.
14 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
15 - new method $state->swap_sv.
16 - added section on "windows process emulation" to the manpage,
17 after a not-so-fruitful (nor-friendly) "discussion" with chip
18 salzenberg (discussion implies arguments, but his only arguments
19 were ad-hominems, one wonders why he started it in the first
20 place). I hope this explains it well enough for him to understand,
21 and maybe well enough for others to understand.
22 - use common::sense everywhere now.
23 - idle callbacks are no longer supported, use idle coros instead.
24 - print a thread listing when a deadlock is detected.
25
265.17 Sat Aug 22 23:09:31 CEST 2009
27 - work around a bug in the perl debugger causing crashes
28 when running under the debugger by marking _pool_handler as nodebug.
29 - speed up Coro::async considerably.
30 - try some hacks to get netbsd to work "more often" - their broken
31 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
32 - convert Coro to AE 5.0 API.
33
345.162 Tue Jul 28 04:04:03 CEST 2009
35 - perl 5.8.2 is now minimum requirement.
36 - skip t/19_handle.t on broken windows perls.
37
385.161 Wed Jul 22 04:47:38 CEST 2009
39 - Coro::AnyEvent::poll could have a different prototype when EV was
40 used as backend (analyzed by Tatsuhiko Miyagawa).
41 - Coro::AnyEvent errornously initialised the event loop when loaded,
42 not on demand.
43 - try to workaround rare */t/01_unblock.t failures.
44
455.16 Tue Jul 21 01:44:37 CEST 2009
46 - Coro::AnyEvent failed to hook into the event loop
47 when no threads had been readied between detecting
48 the event loop and actually running it.
49 - considerably speed up Coro::Select by taking avdantage
50 of AnyEvent > 4.8 and some other optimisations.
51 - implement paragraph readline mode in Coro::Handle
52 (based on patches by Zsbán Ambrus).
53 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
54 and analyzed by Yasuhiro MATSUMOTO).
55 - clarified libcoro license and copyright.
56 - someone stole my EXTRA_META!!!
57 - implement Coro::Select::patch_pp_sselect and it's brother,
58 for hardcode select overriding.
59
605.151 Mon Jul 6 05:41:57 CEST 2009
61 - backport to windows process emulation code again (patch by
62 Yasuhiro MATSUMOTO).
63 - slightly update Coro::MakeMaker.
64
655.15 Tue Jun 30 10:28:06 CEST 2009
66 - deprecate Coro::Socket, document how to get ipv6 support via
67 AnyEvent::Socket instead.
68 - implement signal->wait ($cb) interface, similar to semaphores.
69 - work around SvOK not supporting getmagic, so we have to getmagic
70 to test for undef :/ (reported by Matthias Waldorf).
71 - load Coro::AnyEvent in all modules using AnyEvent.
72 - work around perl corrupting our internal data structures,
73 reported by Tokuhiro Matsuno.
74 - enable per-coroutine real and cpu time gathering
75 (Coro::State::enable_times).
76
775.14 Wed Jun 24 01:37:48 CEST 2009
78 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
79 as this seems to have been a difficult concept (poll, sleep, idle,
80 idle_upto).
81 - add Coro::AnyEvent::readable/writable functions.
82 - clarify Coro::EV/Event/AnyEvent manpages.
83 - free per-thread global scalars in the thread calling ->cancel, to
84 avoid crashes when $_, $@ etc., are magical but some of those
85 had already been freed.
86 - "unexperimentalise" the callback interface for Coro::Semaphore.
87 - speed up ready queue management/context switching by using a linked
88 list instead of an array (~5-10%).
89 - implement "watch" command in Coro::Debug shells.
90 - for fun, implement time-slicing as an example in the manpage.
91 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
92 Coro::Event, use the normal AnyEvent handling instead of dieing
93 (the same is true for Coro::Handle).
94 - properly document Coro::EV::timed_io_once.
95 - avoid unneccessary ->cancel calls in Coro::Handle.
96 - maybe make it work on mingw32 with win32 backend
97 (based on patch by Yasuhiro Matsumoto).
98
995.132 Fri May 29 09:00:39 CEST 2009
100 - do not keep a reference to the argument itself in
101 Coro::Semaphore::guard, as it could change later.
102 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
103 should support a prepare callback.
104
1055.131 Mon Mar 16 23:20:37 CET 2009
106 - implement and document Coro->suspend, Coro->resume.
107 - fix Coro::Select implementation to not (often) close
108 the passed file descriptors (testcase provided by pippijn).
109
1105.13 Mon Dec 15 21:51:42 CET 2008
111 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
112 - don't set diehook to C<undef> but instead to NULL, to avoid
113 spurious warnings.
114 - fix a lot of bugs in Coro::SemaphoreSet.
115 - Coro::SemaphoreSet will less often create a semaphore needlessly.
116 - add Coro::SemaphoreSet::count and wait methods.
117 - take advantage of the new Guard module.
118 - deprecate Coro::guard.
119 - try to fix the dreaded 01_unblock tests once more. I hate it when
120 testsuites need more fixing than the code they are supposed to test.
121 - croak in more cases when a required callback isn't resolvable.
122 - fix some minor issues in Coro::State->call/eval.
123 - use current coroutine context instead of a temporary one
124 when temporarily switching to another coroutine.
125 - do not call C-level on_destroy handlers during global destruction,
126 to avoid needless segfaults.
127
1285.12 Sun Dec 7 13:30:38 CET 2008
129 - add default config for MirOS, which seems to be a bug-to-bug
130 compatible fork of openbsd ("world domination by releasing
131 openbsd cvs before the openbsd folks do it" or so :).
132 - free_padlist did destroy the names pad, not good, but didn't
133 seem to bother perl - this could fix issues such as eval ""
134 inside a function called from multiple coroutines.
135 - use a different method to detect destruction time.
136 - be more careful when freeing padlists just before global
137 destruction.
138 - fixed and expanded the call/cc example.
139 - renamed _terminate to _coro_run.
140 - new method Coro::Channel->shutdown.
141 - try pthreads on openbsd <4.4 (broken sigaltstack, will
142 pthreads fare better?).
143 - be less picky about destroying "a" running coroutine.
144
1455.11 Tue Nov 25 21:49:05 CET 2008
146 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
147 working code with failed assertions, introducing more bugs than
148 it fixes, requiring elaborate workarounds :(
149
1505.1 Mon Nov 24 08:54:59 CET 2008
151 - wrote a small introductory tutorial - Coro::Intro.
9 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. 152 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
10 - Coro::Select did errornously dup the file descriptors 153 - Coro::Select did errornously dup the file descriptors
11 and didn't work with all AnyEvent backends. 154 and didn't work with all AnyEvent backends.
155 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
156 LWP data transfers.
12 - disassociate c contexts from coro objects - this is agruably more 157 - disassociate c contexts from coro objects - this is agruably more
13 correct, but mostly allows sharing of cctxs between coro and state 158 correct, but mostly allows sharing of cctxs between coro and state
14 objects, for added memory savings and speed increases. 159 objects, for added memory savings and speed increases.
15 - bumped $Coro::POOL_RSS up to 32kb by default. 160 - bumped $Coro::POOL_RSS up to 32kb by default.
16 - no longer set the optype to OP_CUSTOM, as B::* understandably 161 - no longer set the optype to OP_CUSTOM, as B::* understandably
17 doesn't like this very much (and we *are* a type of entersub). 162 doesn't like this very much (and we *are* a type of entersub).
18 - implement state cloning, just to prove that call/cc can be done. 163 - implement state cloning, just to prove that call/cc can be done.
164 - automatically load Coro::AnyEvent in Coro::Handle.
165 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
166 do not have this method (and don't need it either).
167 - speed up generic anyevent methods in Coro::Handle by using rouse
168 callbacks.
169 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
170 others. It also makes the debugger happier, as you can trace
171 through the idle threads now.
172 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
173 - eg/event was pretty broken.
19 - better 5.8.6 compatibility. 174 - better 5.8.6 compatibility.
