8 TODO: Coro/Intro 95.24 Sat Oct 23 11:27:12 CEST 2010
10 - port to the EV 4.0 API.
11 - work around bugs in mingw32, making strawberry perl work
12 out of the box.
13 - correctly modify Coro::AIO function prototypes
14 so that they reflect the "no optional parameters" rule.
15 - "ported" libcoro to C++.
16
175.23 Mon May 17 18:50:42 CEST 2010
18 - be more resistant to ordering changes when initialising
19 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
20 Waldorf).
21 - document that perl 5.12 deliberately removed support for cloning.
22
235.22 Wed Apr 14 03:55:35 CEST 2010
24 - correctly return udnef on errors in Coro::Handle::read/write
25 (testcase by Marc Mims).
26 - convert Coro::Util into a "perl compatibility wrapper" - the functions
27 are less useful now, but are drop-in replacements for existing
28 functions, listing better alternatives in the documentation. This also
29 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
30 with Coro::Util::inet_aton.
31 - do not override $Coro::idle unconditionally in Coro.pm, as other
32 modules could have provided their own idle coro already
33 (for exmaple, Coro::AnyEvent).
34 - fix Coro::Util::gethost* functions.
35 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
36
375.21 Wed Dec 16 07:19:51 CET 2009
38 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
39 together.
40 - add some examples on how to combine other event loops with Coro in
41 Coro::AnyEvent, and how to run it (and not to block). Seems to be
42 the most common source of confusion.
43 - try to catch people naively blocking in an event callback.
44 - work around the perl filehandle bug issue in conjunction with
45 older common::sense (as indirectly pointed out by ZSystem).
46 - clarify the "not from signal handlers" section.
47
485.2 Sun Oct 4 14:54:24 CEST 2009
49 - Coro::Storable destroyed the prototypes of the functions it wrapped.
50 - export rouse_cb and rouse_wait by default now.
51 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
52 - new method $state->swap_sv.
53 - added section on "windows process emulation" to the manpage,
54 after a not-so-fruitful (nor-friendly) "discussion" with chip
55 salzenberg (discussion implies arguments, but his only arguments
56 were ad-hominems, one wonders why he started it in the first
57 place). I hope this explains it well enough for him to understand,
58 and maybe well enough for others to understand.
59 - use common::sense everywhere now.
60 - idle callbacks are no longer supported, use idle coros instead.
61 - print a thread listing when a deadlock is detected.
62
635.17 Sat Aug 22 23:09:31 CEST 2009
64 - work around a bug in the perl debugger causing crashes
65 when running under the debugger by marking _pool_handler as nodebug.
66 - speed up Coro::async considerably.
67 - try some hacks to get netbsd to work "more often" - their broken
68 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
69 - convert Coro to AE 5.0 API.
70
715.162 Tue Jul 28 04:04:03 CEST 2009
72 - perl 5.8.2 is now minimum requirement.
73 - skip t/19_handle.t on broken windows perls.
74
755.161 Wed Jul 22 04:47:38 CEST 2009
76 - Coro::AnyEvent::poll could have a different prototype when EV was
77 used as backend (analyzed by Tatsuhiko Miyagawa).
78 - Coro::AnyEvent errornously initialised the event loop when loaded,
79 not on demand.
80 - try to workaround rare */t/01_unblock.t failures.
81
825.16 Tue Jul 21 01:44:37 CEST 2009
83 - Coro::AnyEvent failed to hook into the event loop
84 when no threads had been readied between detecting
85 the event loop and actually running it.
86 - considerably speed up Coro::Select by taking avdantage
87 of AnyEvent > 4.8 and some other optimisations.
88 - implement paragraph readline mode in Coro::Handle
89 (based on patches by Zsbán Ambrus).
90 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
91 and analyzed by Yasuhiro MATSUMOTO).
92 - clarified libcoro license and copyright.
93 - someone stole my EXTRA_META!!!
94 - implement Coro::Select::patch_pp_sselect and it's brother,
95 for hardcode select overriding.
96
975.151 Mon Jul 6 05:41:57 CEST 2009
98 - backport to windows process emulation code again (patch by
99 Yasuhiro MATSUMOTO).
100 - slightly update Coro::MakeMaker.
101
1025.15 Tue Jun 30 10:28:06 CEST 2009
103 - deprecate Coro::Socket, document how to get ipv6 support via
104 AnyEvent::Socket instead.
105 - implement signal->wait ($cb) interface, similar to semaphores.
106 - work around SvOK not supporting getmagic, so we have to getmagic
107 to test for undef :/ (reported by Matthias Waldorf).
108 - load Coro::AnyEvent in all modules using AnyEvent.
109 - work around perl corrupting our internal data structures,
110 reported by Tokuhiro Matsuno.
111 - enable per-coroutine real and cpu time gathering
112 (Coro::State::enable_times).
113
1145.14 Wed Jun 24 01:37:48 CEST 2009
115 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
116 as this seems to have been a difficult concept (poll, sleep, idle,
117 idle_upto).
118 - add Coro::AnyEvent::readable/writable functions.
119 - clarify Coro::EV/Event/AnyEvent manpages.
120 - free per-thread global scalars in the thread calling ->cancel, to
121 avoid crashes when $_, $@ etc., are magical but some of those
122 had already been freed.
123 - "unexperimentalise" the callback interface for Coro::Semaphore.
124 - speed up ready queue management/context switching by using a linked
125 list instead of an array (~5-10%).
126 - implement "watch" command in Coro::Debug shells.
127 - for fun, implement time-slicing as an example in the manpage.
128 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
129 Coro::Event, use the normal AnyEvent handling instead of dieing
130 (the same is true for Coro::Handle).
131 - properly document Coro::EV::timed_io_once.
132 - avoid unneccessary ->cancel calls in Coro::Handle.
133 - maybe make it work on mingw32 with win32 backend
134 (based on patch by Yasuhiro Matsumoto).
135
1365.132 Fri May 29 09:00:39 CEST 2009
137 - do not keep a reference to the argument itself in
138 Coro::Semaphore::guard, as it could change later.
139 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
140 should support a prepare callback.
141
1425.131 Mon Mar 16 23:20:37 CET 2009
143 - implement and document Coro->suspend, Coro->resume.
144 - fix Coro::Select implementation to not (often) close
145 the passed file descriptors (testcase provided by pippijn).
146
1475.13 Mon Dec 15 21:51:42 CET 2008
148 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
149 - don't set diehook to C<undef> but instead to NULL, to avoid
150 spurious warnings.
151 - fix a lot of bugs in Coro::SemaphoreSet.
152 - Coro::SemaphoreSet will less often create a semaphore needlessly.
153 - add Coro::SemaphoreSet::count and wait methods.
154 - take advantage of the new Guard module.
155 - deprecate Coro::guard.
156 - try to fix the dreaded 01_unblock tests once more. I hate it when
157 testsuites need more fixing than the code they are supposed to test.
158 - croak in more cases when a required callback isn't resolvable.
159 - fix some minor issues in Coro::State->call/eval.
160 - use current coroutine context instead of a temporary one
161 when temporarily switching to another coroutine.
162 - do not call C-level on_destroy handlers during global destruction,
163 to avoid needless segfaults.
164
1655.12 Sun Dec 7 13:30:38 CET 2008
166 - add default config for MirOS, which seems to be a bug-to-bug
167 compatible fork of openbsd ("world domination by releasing
168 openbsd cvs before the openbsd folks do it" or so :).
169 - free_padlist did destroy the names pad, not good, but didn't
170 seem to bother perl - this could fix issues such as eval ""
171 inside a function called from multiple coroutines.
172 - use a different method to detect destruction time.
173 - be more careful when freeing padlists just before global
174 destruction.
175 - fixed and expanded the call/cc example.
176 - renamed _terminate to _coro_run.
177 - new method Coro::Channel->shutdown.
178 - try pthreads on openbsd <4.4 (broken sigaltstack, will
179 pthreads fare better?).
180 - be less picky about destroying "a" running coroutine.
181
1825.11 Tue Nov 25 21:49:05 CET 2008
183 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
184 working code with failed assertions, introducing more bugs than
185 it fixes, requiring elaborate workarounds :(
186
1875.1 Mon Nov 24 08:54:59 CET 2008
9 - wrote a small introduction - Coro::Intro. 188 - wrote a small introductory tutorial - Coro::Intro.
10 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. 189 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
11 - Coro::Select did errornously dup the file descriptors 190 - Coro::Select did errornously dup the file descriptors
12 and didn't work with all AnyEvent backends. 191 and didn't work with all AnyEvent backends.
192 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
193 LWP data transfers.
13 - disassociate c contexts from coro objects - this is agruably more 194 - disassociate c contexts from coro objects - this is agruably more
14 correct, but mostly allows sharing of cctxs between coro and state 195 correct, but mostly allows sharing of cctxs between coro and state
15 objects, for added memory savings and speed increases. 196 objects, for added memory savings and speed increases.
16 - bumped $Coro::POOL_RSS up to 32kb by default. 197 - bumped $Coro::POOL_RSS up to 32kb by default.
17 - no longer set the optype to OP_CUSTOM, as B::* understandably 198 - no longer set the optype to OP_CUSTOM, as B::* understandably
18 doesn't like this very much (and we *are* a type of entersub). 199 doesn't like this very much (and we *are* a type of entersub).
19 - implement state cloning, just to prove that call/cc can be done. 200 - implement state cloning, just to prove that call/cc can be done.
20 - automatically load Coro::AnyEvent in Coro::Handle. 201 - automatically load Coro::AnyEvent in Coro::Handle.
202 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
203 do not have this method (and don't need it either).
204 - speed up generic anyevent methods in Coro::Handle by using rouse
205 callbacks.
206 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
207 others. It also makes the debugger happier, as you can trace
208 through the idle threads now.
209 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
210 - eg/event was pretty broken.
21 - better 5.8.6 compatibility. 211 - better 5.8.6 compatibility.
