2 2
3TODO: should explore PerlIO::coroaio (perl leaks like hell). 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: maybe implement a default message channel, very much like Erlang's 4TODO: unready_all
5 actor model (which is cool in a lot of important aspects (failures!), 5TODO: myhttpd header parsing
6 but very lacking in others (higher level ipc)). 6TODO: channel->maxsize(newsize)?
7 7
8TODO: testcancel 8 - convert Coro::Util into a "perl compatibility wrapper" - the functions
9TODO: guard as SLF - to avoid deadlocks. 9 are less useful now, but are drop-in replacements for existing
10 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 10 functions, listing better alternatives in the documentation. This also
11 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
12 with Coro::Util::inet_aton.
13 - do not override $Coro::idle unconditionally in Coro.pm, as other
14 modules could have provided their own idle coro already
15 (for exmaple, Coro::AnyEvent).
16 - fix Coro::Util::gethost* functions.
11 17
125.0 185.21 Wed Dec 16 07:19:51 CET 2009
19 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
20 together.
21 - add some examples on how to combine other event loops with Coro in
22 Coro::AnyEvent, and how to run it (and not to block). Seems to be
23 the most common source of confusion.
24 - try to catch people naively blocking in an event callback.
25 - work around the perl filehandle bug issue in conjunction with
26 older common::sense (as indirectly pointed out by ZSystem).
27 - clarify the "not from signal handlers" section.
28
295.2 Sun Oct 4 14:54:24 CEST 2009
30 - Coro::Storable destroyed the prototypes of the functions it wrapped.
31 - export rouse_cb and rouse_wait by default now.
32 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
33 - new method $state->swap_sv.
34 - added section on "windows process emulation" to the manpage,
35 after a not-so-fruitful (nor-friendly) "discussion" with chip
36 salzenberg (discussion implies arguments, but his only arguments
37 were ad-hominems, one wonders why he started it in the first
38 place). I hope this explains it well enough for him to understand,
39 and maybe well enough for others to understand.
40 - use common::sense everywhere now.
41 - idle callbacks are no longer supported, use idle coros instead.
42 - print a thread listing when a deadlock is detected.
43
445.17 Sat Aug 22 23:09:31 CEST 2009
45 - work around a bug in the perl debugger causing crashes
46 when running under the debugger by marking _pool_handler as nodebug.
47 - speed up Coro::async considerably.
48 - try some hacks to get netbsd to work "more often" - their broken
49 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
50 - convert Coro to AE 5.0 API.
51
525.162 Tue Jul 28 04:04:03 CEST 2009
53 - perl 5.8.2 is now minimum requirement.
54 - skip t/19_handle.t on broken windows perls.
55
565.161 Wed Jul 22 04:47:38 CEST 2009
57 - Coro::AnyEvent::poll could have a different prototype when EV was
58 used as backend (analyzed by Tatsuhiko Miyagawa).
59 - Coro::AnyEvent errornously initialised the event loop when loaded,
60 not on demand.
61 - try to workaround rare */t/01_unblock.t failures.
62
635.16 Tue Jul 21 01:44:37 CEST 2009
64 - Coro::AnyEvent failed to hook into the event loop
65 when no threads had been readied between detecting
66 the event loop and actually running it.
67 - considerably speed up Coro::Select by taking avdantage
68 of AnyEvent > 4.8 and some other optimisations.
69 - implement paragraph readline mode in Coro::Handle
70 (based on patches by Zsbán Ambrus).
71 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
72 and analyzed by Yasuhiro MATSUMOTO).
73 - clarified libcoro license and copyright.
74 - someone stole my EXTRA_META!!!
75 - implement Coro::Select::patch_pp_sselect and it's brother,
76 for hardcode select overriding.
77
785.151 Mon Jul 6 05:41:57 CEST 2009
79 - backport to windows process emulation code again (patch by
80 Yasuhiro MATSUMOTO).
81 - slightly update Coro::MakeMaker.
82
835.15 Tue Jun 30 10:28:06 CEST 2009
84 - deprecate Coro::Socket, document how to get ipv6 support via
85 AnyEvent::Socket instead.
86 - implement signal->wait ($cb) interface, similar to semaphores.
87 - work around SvOK not supporting getmagic, so we have to getmagic
88 to test for undef :/ (reported by Matthias Waldorf).
89 - load Coro::AnyEvent in all modules using AnyEvent.
90 - work around perl corrupting our internal data structures,
91 reported by Tokuhiro Matsuno.
92 - enable per-coroutine real and cpu time gathering
93 (Coro::State::enable_times).
94
955.14 Wed Jun 24 01:37:48 CEST 2009
96 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
97 as this seems to have been a difficult concept (poll, sleep, idle,
98 idle_upto).
99 - add Coro::AnyEvent::readable/writable functions.
100 - clarify Coro::EV/Event/AnyEvent manpages.
101 - free per-thread global scalars in the thread calling ->cancel, to
102 avoid crashes when $_, $@ etc., are magical but some of those
103 had already been freed.
104 - "unexperimentalise" the callback interface for Coro::Semaphore.
105 - speed up ready queue management/context switching by using a linked
106 list instead of an array (~5-10%).
107 - implement "watch" command in Coro::Debug shells.
108 - for fun, implement time-slicing as an example in the manpage.
109 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
110 Coro::Event, use the normal AnyEvent handling instead of dieing
111 (the same is true for Coro::Handle).
112 - properly document Coro::EV::timed_io_once.
113 - avoid unneccessary ->cancel calls in Coro::Handle.
114 - maybe make it work on mingw32 with win32 backend
115 (based on patch by Yasuhiro Matsumoto).
116
1175.132 Fri May 29 09:00:39 CEST 2009
118 - do not keep a reference to the argument itself in
119 Coro::Semaphore::guard, as it could change later.
120 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
121 should support a prepare callback.
122
1235.131 Mon Mar 16 23:20:37 CET 2009
124 - implement and document Coro->suspend, Coro->resume.
125 - fix Coro::Select implementation to not (often) close
126 the passed file descriptors (testcase provided by pippijn).
127
1285.13 Mon Dec 15 21:51:42 CET 2008
129 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
130 - don't set diehook to C<undef> but instead to NULL, to avoid
131 spurious warnings.
132 - fix a lot of bugs in Coro::SemaphoreSet.
133 - Coro::SemaphoreSet will less often create a semaphore needlessly.
134 - add Coro::SemaphoreSet::count and wait methods.
135 - take advantage of the new Guard module.
136 - deprecate Coro::guard.
137 - try to fix the dreaded 01_unblock tests once more. I hate it when
138 testsuites need more fixing than the code they are supposed to test.
139 - croak in more cases when a required callback isn't resolvable.
140 - fix some minor issues in Coro::State->call/eval.
141 - use current coroutine context instead of a temporary one
142 when temporarily switching to another coroutine.
143 - do not call C-level on_destroy handlers during global destruction,
144 to avoid needless segfaults.
145
1465.12 Sun Dec 7 13:30:38 CET 2008
147 - add default config for MirOS, which seems to be a bug-to-bug
148 compatible fork of openbsd ("world domination by releasing
149 openbsd cvs before the openbsd folks do it" or so :).
150 - free_padlist did destroy the names pad, not good, but didn't
151 seem to bother perl - this could fix issues such as eval ""
152 inside a function called from multiple coroutines.
153 - use a different method to detect destruction time.
154 - be more careful when freeing padlists just before global
155 destruction.
156 - fixed and expanded the call/cc example.
157 - renamed _terminate to _coro_run.
158 - new method Coro::Channel->shutdown.
159 - try pthreads on openbsd <4.4 (broken sigaltstack, will
160 pthreads fare better?).
161 - be less picky about destroying "a" running coroutine.
162
1635.11 Tue Nov 25 21:49:05 CET 2008
164 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
165 working code with failed assertions, introducing more bugs than
166 it fixes, requiring elaborate workarounds :(
167
1685.1 Mon Nov 24 08:54:59 CET 2008
169 - wrote a small introductory tutorial - Coro::Intro.
170 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
171 - Coro::Select did errornously dup the file descriptors
172 and didn't work with all AnyEvent backends.
173 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
174 LWP data transfers.
175 - disassociate c contexts from coro objects - this is agruably more
176 correct, but mostly allows sharing of cctxs between coro and state
177 objects, for added memory savings and speed increases.
178 - bumped $Coro::POOL_RSS up to 32kb by default.
179 - no longer set the optype to OP_CUSTOM, as B::* understandably
180 doesn't like this very much (and we *are* a type of entersub).
181 - implement state cloning, just to prove that call/cc can be done.
182 - automatically load Coro::AnyEvent in Coro::Handle.
183 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
184 do not have this method (and don't need it either).
185 - speed up generic anyevent methods in Coro::Handle by using rouse
186 callbacks.
187 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
188 others. It also makes the debugger happier, as you can trace
189 through the idle threads now.
190 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
191 - eg/event was pretty broken.
192 - better 5.8.6 compatibility.

213 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
214 conversion of callback-style to blocking-style.
215 - new methods $coro->schedule_to and ->cede_to, to specifically
216 schedule or cede to a specific coroutine.

56 making signals reliable for the first time. 242 making signals reliable for the first time.
243 - used new SLF interface and other optimisations to speed up async_pool
244 by a factor of two. It also doesn't rely on perl's exception mechanism
245 to exit anymore. The overhead for terminating an async_pool, coro over
246 a normal async is now very small.
247 - sped up coroutine creation/destruction by 40%.
