11
125.24 Sat Oct 23 11:27:12 CEST 2010
13 - port to the EV 4.0 API.
14 - work around bugs in mingw32, making strawberry perl work
15 out of the box.
16 - correctly modify Coro::AIO function prototypes
17 so that they reflect the "no optional parameters" rule.
18 - "ported" libcoro to C++.
19
205.23 Mon May 17 18:50:42 CEST 2010
21 - be more resistant to ordering changes when initialising
22 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
23 Waldorf).
24 - document that perl 5.12 deliberately removed support for cloning.
25
265.22 Wed Apr 14 03:55:35 CEST 2010
27 - correctly return udnef on errors in Coro::Handle::read/write
28 (testcase by Marc Mims).
29 - convert Coro::Util into a "perl compatibility wrapper" - the functions
30 are less useful now, but are drop-in replacements for existing
31 functions, listing better alternatives in the documentation. This also
32 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
33 with Coro::Util::inet_aton.
34 - do not override $Coro::idle unconditionally in Coro.pm, as other
35 modules could have provided their own idle coro already
36 (for exmaple, Coro::AnyEvent).
37 - fix Coro::Util::gethost* functions.
38 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
39
405.21 Wed Dec 16 07:19:51 CET 2009
41 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
42 together.
43 - add some examples on how to combine other event loops with Coro in
44 Coro::AnyEvent, and how to run it (and not to block). Seems to be
45 the most common source of confusion.
46 - try to catch people naively blocking in an event callback.
47 - work around the perl filehandle bug issue in conjunction with
48 older common::sense (as indirectly pointed out by ZSystem).
49 - clarify the "not from signal handlers" section.
50
515.2 Sun Oct 4 14:54:24 CEST 2009
52 - Coro::Storable destroyed the prototypes of the functions it wrapped.
53 - export rouse_cb and rouse_wait by default now.
54 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
55 - new method $state->swap_sv.
56 - added section on "windows process emulation" to the manpage,
57 after a not-so-fruitful (nor-friendly) "discussion" with chip
58 salzenberg (discussion implies arguments, but his only arguments
59 were ad-hominems, one wonders why he started it in the first
60 place). I hope this explains it well enough for him to understand,
61 and maybe well enough for others to understand.
62 - use common::sense everywhere now.
63 - idle callbacks are no longer supported, use idle coros instead.
64 - print a thread listing when a deadlock is detected.
65
665.17 Sat Aug 22 23:09:31 CEST 2009
67 - work around a bug in the perl debugger causing crashes
68 when running under the debugger by marking _pool_handler as nodebug.
69 - speed up Coro::async considerably.
70 - try some hacks to get netbsd to work "more often" - their broken
71 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
72 - convert Coro to AE 5.0 API.
73
745.162 Tue Jul 28 04:04:03 CEST 2009
75 - perl 5.8.2 is now minimum requirement.
76 - skip t/19_handle.t on broken windows perls.
77
785.161 Wed Jul 22 04:47:38 CEST 2009
79 - Coro::AnyEvent::poll could have a different prototype when EV was
80 used as backend (analyzed by Tatsuhiko Miyagawa).
81 - Coro::AnyEvent errornously initialised the event loop when loaded,
82 not on demand.
83 - try to workaround rare */t/01_unblock.t failures.
84
855.16 Tue Jul 21 01:44:37 CEST 2009
86 - Coro::AnyEvent failed to hook into the event loop
87 when no threads had been readied between detecting
88 the event loop and actually running it.
89 - considerably speed up Coro::Select by taking avdantage
90 of AnyEvent > 4.8 and some other optimisations.
91 - implement paragraph readline mode in Coro::Handle
92 (based on patches by Zsbán Ambrus).
93 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
94 and analyzed by Yasuhiro MATSUMOTO).
95 - clarified libcoro license and copyright.
96 - someone stole my EXTRA_META!!!
97 - implement Coro::Select::patch_pp_sselect and it's brother,
98 for hardcode select overriding.
99
1005.151 Mon Jul 6 05:41:57 CEST 2009
101 - backport to windows process emulation code again (patch by
102 Yasuhiro MATSUMOTO).
103 - slightly update Coro::MakeMaker.
104
1055.15 Tue Jun 30 10:28:06 CEST 2009
106 - deprecate Coro::Socket, document how to get ipv6 support via
107 AnyEvent::Socket instead.
108 - implement signal->wait ($cb) interface, similar to semaphores.
109 - work around SvOK not supporting getmagic, so we have to getmagic
110 to test for undef :/ (reported by Matthias Waldorf).
111 - load Coro::AnyEvent in all modules using AnyEvent.
112 - work around perl corrupting our internal data structures,
113 reported by Tokuhiro Matsuno.
114 - enable per-coroutine real and cpu time gathering
115 (Coro::State::enable_times).
116
1175.14 Wed Jun 24 01:37:48 CEST 2009
118 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
119 as this seems to have been a difficult concept (poll, sleep, idle,
120 idle_upto).
121 - add Coro::AnyEvent::readable/writable functions.
122 - clarify Coro::EV/Event/AnyEvent manpages.
123 - free per-thread global scalars in the thread calling ->cancel, to
124 avoid crashes when $_, $@ etc., are magical but some of those
125 had already been freed.
126 - "unexperimentalise" the callback interface for Coro::Semaphore.
127 - speed up ready queue management/context switching by using a linked
128 list instead of an array (~5-10%).
129 - implement "watch" command in Coro::Debug shells.
130 - for fun, implement time-slicing as an example in the manpage.
131 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
132 Coro::Event, use the normal AnyEvent handling instead of dieing
133 (the same is true for Coro::Handle).
134 - properly document Coro::EV::timed_io_once.
135 - avoid unneccessary ->cancel calls in Coro::Handle.
136 - maybe make it work on mingw32 with win32 backend
137 (based on patch by Yasuhiro Matsumoto).
138
1395.132 Fri May 29 09:00:39 CEST 2009
140 - do not keep a reference to the argument itself in
141 Coro::Semaphore::guard, as it could change later.
142 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
143 should support a prepare callback.
144
1455.131 Mon Mar 16 23:20:37 CET 2009
146 - implement and document Coro->suspend, Coro->resume.
147 - fix Coro::Select implementation to not (often) close
148 the passed file descriptors (testcase provided by pippijn).
149
1505.13 Mon Dec 15 21:51:42 CET 2008
151 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
152 - don't set diehook to C<undef> but instead to NULL, to avoid
153 spurious warnings.
154 - fix a lot of bugs in Coro::SemaphoreSet.
155 - Coro::SemaphoreSet will less often create a semaphore needlessly.
156 - add Coro::SemaphoreSet::count and wait methods.
157 - take advantage of the new Guard module.
158 - deprecate Coro::guard.
159 - try to fix the dreaded 01_unblock tests once more. I hate it when
160 testsuites need more fixing than the code they are supposed to test.
161 - croak in more cases when a required callback isn't resolvable.
162 - fix some minor issues in Coro::State->call/eval.
163 - use current coroutine context instead of a temporary one
164 when temporarily switching to another coroutine.
165 - do not call C-level on_destroy handlers during global destruction,
166 to avoid needless segfaults.
167
1685.12 Sun Dec 7 13:30:38 CET 2008
169 - add default config for MirOS, which seems to be a bug-to-bug
170 compatible fork of openbsd ("world domination by releasing
171 openbsd cvs before the openbsd folks do it" or so :).
172 - free_padlist did destroy the names pad, not good, but didn't
173 seem to bother perl - this could fix issues such as eval ""
174 inside a function called from multiple coroutines.
175 - use a different method to detect destruction time.
176 - be more careful when freeing padlists just before global
177 destruction.
178 - fixed and expanded the call/cc example.
179 - renamed _terminate to _coro_run.
180 - new method Coro::Channel->shutdown.
181 - try pthreads on openbsd <4.4 (broken sigaltstack, will
182 pthreads fare better?).
183 - be less picky about destroying "a" running coroutine.
184
1855.11 Tue Nov 25 21:49:05 CET 2008
186 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
187 working code with failed assertions, introducing more bugs than
188 it fixes, requiring elaborate workarounds :(
189
1905.1 Mon Nov 24 08:54:59 CET 2008
191 - wrote a small introductory tutorial - Coro::Intro.
9 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. 192 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
10 - Coro::Select did errornously dup the file descriptors 193 - Coro::Select did errornously dup the file descriptors
11 and didn't work with all AnyEvent backends. 194 and didn't work with all AnyEvent backends.
195 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
196 LWP data transfers.
12 - disassociate c contexts from coro objects - this is agruably more 197 - disassociate c contexts from coro objects - this is agruably more
13 correct, but mostly allows sharing of cctxs between coro and state 198 correct, but mostly allows sharing of cctxs between coro and state
14 objects, for added memory savings and speed increases. 199 objects, for added memory savings and speed increases.
15 - bumped $Coro::POOL_RSS up to 32kb by default. 200 - bumped $Coro::POOL_RSS up to 32kb by default.
16 - no longer set the optype to OP_CUSTOM, as B::* understandably 201 - 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). 202 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. 203 - implement state cloning, just to prove that call/cc can be done.
204 - automatically load Coro::AnyEvent in Coro::Handle.
205 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
206 do not have this method (and don't need it either).
207 - speed up generic anyevent methods in Coro::Handle by using rouse
208 callbacks.
209 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
210 others. It also makes the debugger happier, as you can trace
211 through the idle threads now.
212 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
213 - eg/event was pretty broken.
19 - better 5.8.6 compatibility. 214 - better 5.8.6 compatibility.
