1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
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: channel->maxsize(newsize)?
5 actor model (which is cool in a lot of important aspects (failures!), 5TODO: http://www.microsoft.com/msj/archive/s2ce.aspx
6 but very lacking in others (higher level ipc)).
7 6
8TODO: async_pool to SLF 7 - croak when a coro being cancelled tries to block (e.g. while
9TODO: _cancel to xs 8 executing a guard block), instead of crashing or deadlocking.
105.0 9 - implement a Coro->safe_cancel method that might fail, but
10 cancels in a "safer" way if it succeeds.
11 - implement Coro->cancel in XS for a 20% speed improvement, and to
12 be able to implement mutual cancellation.
13 - cancelling a coro while it itself is cancelling another coro is
14 now supported and working, instead of triggering an assertion.
15 - be a bit more crash-resistant when calling (buggy) on_destroy
16 callbacks (best effort).
17 - move on_destroy into the slf_frame, to allow extension slf
18 functions to have destructors.
19
205.372 Wed Feb 23 06:14:30 CET 2011
21 - apparently mingw doesn't provide a working gettimeofday, try to
22 work around that by relying on Time::HiRes (indirectly brought to
23 my attention by Max Maischein).
24 - fix some portability issues when Time::HiRes was used.
25
265.371 Mon Feb 21 14:36:08 CET 2011
27 - backport to windows process emulation code again.
28
295.37 Sat Feb 19 07:49:44 CET 2011
30 - add a big "Coro thread life cycle" section to "man Coro".
31 - try a tentative workaround against the breakage that 5.13 has
32 introduced without depreciation period. sigh.
33 - no longer use Time::HiRes if gettimeofday is available, which
34 saves quite a lot of memory.
35
365.36 Sun Feb 13 05:33:41 CET 2011
37 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
38 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
39 method call.
40 - undocument Coro::Timer::sleep and obsolete whole module.
41 - optimise Coro::Timer::timeout memory and cpu usage.
42 - slightly updated Coro::Intro for recent changes.
43 - do not initialise PL_dirty anymore.
44
455.25 Thu Nov 11 01:08:39 CET 2010
46 - try a different approach on netbsd - netbsd 5 finally has marginally
47 working pthreads, but still broken ucontext/sigaltstack.
48 - openbsd 4.8 finally got their act together, Coro works out of the box
49 with asm, setjmp and pthreads (no change, just informational).
50
515.24 Sat Oct 23 11:27:12 CEST 2010
52 - port to the EV 4.0 API.
53 - work around bugs in mingw32, making strawberry perl work
54 out of the box.
55 - correctly modify Coro::AIO function prototypes
56 so that they reflect the "no optional parameters" rule.
57 - "ported" libcoro to C++.
58
595.23 Mon May 17 18:50:42 CEST 2010
60 - be more resistant to ordering changes when initialising
61 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
62 Waldorf).
63 - document that perl 5.12 deliberately removed support for cloning.
64
655.22 Wed Apr 14 03:55:35 CEST 2010
66 - correctly return udnef on errors in Coro::Handle::read/write
67 (testcase by Marc Mims).
68 - convert Coro::Util into a "perl compatibility wrapper" - the functions
69 are less useful now, but are drop-in replacements for existing
70 functions, listing better alternatives in the documentation. This also
71 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
72 with Coro::Util::inet_aton.
73 - do not override $Coro::idle unconditionally in Coro.pm, as other
74 modules could have provided their own idle coro already
75 (for exmaple, Coro::AnyEvent).
76 - fix Coro::Util::gethost* functions.
77 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
78
795.21 Wed Dec 16 07:19:51 CET 2009
80 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
81 together.
82 - add some examples on how to combine other event loops with Coro in
83 Coro::AnyEvent, and how to run it (and not to block). Seems to be
84 the most common source of confusion.
85 - try to catch people naively blocking in an event callback.
86 - work around the perl filehandle bug issue in conjunction with
87 older common::sense (as indirectly pointed out by ZSystem).
88 - clarify the "not from signal handlers" section.
89
905.2 Sun Oct 4 14:54:24 CEST 2009
91 - Coro::Storable destroyed the prototypes of the functions it wrapped.
92 - export rouse_cb and rouse_wait by default now.
93 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
94 - new method $state->swap_sv.
95 - added section on "windows process emulation" to the manpage,
96 after a not-so-fruitful (nor-friendly) "discussion" with chip
97 salzenberg (discussion implies arguments, but his only arguments
98 were ad-hominems, one wonders why he started it in the first
99 place). I hope this explains it well enough for him to understand,
100 and maybe well enough for others to understand.
101 - use common::sense everywhere now.
102 - idle callbacks are no longer supported, use idle coros instead.
103 - print a thread listing when a deadlock is detected.
104
1055.17 Sat Aug 22 23:09:31 CEST 2009
106 - work around a bug in the perl debugger causing crashes
107 when running under the debugger by marking _pool_handler as nodebug.
108 - speed up Coro::async considerably.
109 - try some hacks to get netbsd to work "more often" - their broken
110 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
111 - convert Coro to AE 5.0 API.
112
1135.162 Tue Jul 28 04:04:03 CEST 2009
114 - perl 5.8.2 is now minimum requirement.
115 - skip t/19_handle.t on broken windows perls.
116
1175.161 Wed Jul 22 04:47:38 CEST 2009
118 - Coro::AnyEvent::poll could have a different prototype when EV was
119 used as backend (analyzed by Tatsuhiko Miyagawa).
120 - Coro::AnyEvent errornously initialised the event loop when loaded,
121 not on demand.
122 - try to workaround rare */t/01_unblock.t failures.
123
1245.16 Tue Jul 21 01:44:37 CEST 2009
125 - Coro::AnyEvent failed to hook into the event loop
126 when no threads had been readied between detecting
127 the event loop and actually running it.
128 - considerably speed up Coro::Select by taking avdantage
129 of AnyEvent > 4.8 and some other optimisations.
130 - implement paragraph readline mode in Coro::Handle
131 (based on patches by Zsbán Ambrus).
132 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
133 and analyzed by Yasuhiro MATSUMOTO).
134 - clarified libcoro license and copyright.
135 - someone stole my EXTRA_META!!!
136 - implement Coro::Select::patch_pp_sselect and it's brother,
137 for hardcode select overriding.
138
1395.151 Mon Jul 6 05:41:57 CEST 2009
140 - backport to windows process emulation code again (patch by
141 Yasuhiro MATSUMOTO).
142 - slightly update Coro::MakeMaker.
143
1445.15 Tue Jun 30 10:28:06 CEST 2009
145 - deprecate Coro::Socket, document how to get ipv6 support via
146 AnyEvent::Socket instead.
147 - implement signal->wait ($cb) interface, similar to semaphores.
148 - work around SvOK not supporting getmagic, so we have to getmagic
149 to test for undef :/ (reported by Matthias Waldorf).
150 - load Coro::AnyEvent in all modules using AnyEvent.
151 - work around perl corrupting our internal data structures,
152 reported by Tokuhiro Matsuno.
153 - enable per-coroutine real and cpu time gathering
154 (Coro::State::enable_times).
155
1565.14 Wed Jun 24 01:37:48 CEST 2009
157 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
158 as this seems to have been a difficult concept (poll, sleep, idle,
159 idle_upto).
160 - add Coro::AnyEvent::readable/writable functions.
161 - clarify Coro::EV/Event/AnyEvent manpages.
162 - free per-thread global scalars in the thread calling ->cancel, to
163 avoid crashes when $_, $@ etc., are magical but some of those
164 had already been freed.
165 - "unexperimentalise" the callback interface for Coro::Semaphore.
166 - speed up ready queue management/context switching by using a linked
167 list instead of an array (~5-10%).
168 - implement "watch" command in Coro::Debug shells.
169 - for fun, implement time-slicing as an example in the manpage.
170 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
171 Coro::Event, use the normal AnyEvent handling instead of dieing
172 (the same is true for Coro::Handle).
173 - properly document Coro::EV::timed_io_once.
174 - avoid unneccessary ->cancel calls in Coro::Handle.
175 - maybe make it work on mingw32 with win32 backend
176 (based on patch by Yasuhiro Matsumoto).
177
1785.132 Fri May 29 09:00:39 CEST 2009
179 - do not keep a reference to the argument itself in
180 Coro::Semaphore::guard, as it could change later.
181 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
182 should support a prepare callback.
183
1845.131 Mon Mar 16 23:20:37 CET 2009
185 - implement and document Coro->suspend, Coro->resume.
186 - fix Coro::Select implementation to not (often) close
187 the passed file descriptors (testcase provided by pippijn).
188
1895.13 Mon Dec 15 21:51:42 CET 2008
190 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
191 - don't set diehook to C<undef> but instead to NULL, to avoid
192 spurious warnings.
193 - fix a lot of bugs in Coro::SemaphoreSet.
194 - Coro::SemaphoreSet will less often create a semaphore needlessly.
195 - add Coro::SemaphoreSet::count and wait methods.
196 - take advantage of the new Guard module.
197 - deprecate Coro::guard.
198 - try to fix the dreaded 01_unblock tests once more. I hate it when
199 testsuites need more fixing than the code they are supposed to test.
200 - croak in more cases when a required callback isn't resolvable.
201 - fix some minor issues in Coro::State->call/eval.
202 - use current coroutine context instead of a temporary one
203 when temporarily switching to another coroutine.
204 - do not call C-level on_destroy handlers during global destruction,
205 to avoid needless segfaults.
206
2075.12 Sun Dec 7 13:30:38 CET 2008
208 - add default config for MirOS, which seems to be a bug-to-bug
209 compatible fork of openbsd ("world domination by releasing
210 openbsd cvs before the openbsd folks do it" or so :).
211 - free_padlist did destroy the names pad, not good, but didn't
212 seem to bother perl - this could fix issues such as eval ""
213 inside a function called from multiple coroutines.
214 - use a different method to detect destruction time.
215 - be more careful when freeing padlists just before global
216 destruction.
217 - fixed and expanded the call/cc example.
218 - renamed _terminate to _coro_run.
219 - new method Coro::Channel->shutdown.
220 - try pthreads on openbsd <4.4 (broken sigaltstack, will
221 pthreads fare better?).
222 - be less picky about destroying "a" running coroutine.
223
2245.11 Tue Nov 25 21:49:05 CET 2008
225 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
226 working code with failed assertions, introducing more bugs than
227 it fixes, requiring elaborate workarounds :(
228
2295.1 Mon Nov 24 08:54:59 CET 2008
230 - wrote a small introductory tutorial - Coro::Intro.
231 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
232 - Coro::Select did errornously dup the file descriptors
233 and didn't work with all AnyEvent backends.
234 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
235 LWP data transfers.
236 - disassociate c contexts from coro objects - this is agruably more
237 correct, but mostly allows sharing of cctxs between coro and state
238 objects, for added memory savings and speed increases.
239 - bumped $Coro::POOL_RSS up to 32kb by default.
240 - no longer set the optype to OP_CUSTOM, as B::* understandably
241 doesn't like this very much (and we *are* a type of entersub).
242 - implement state cloning, just to prove that call/cc can be done.
243 - automatically load Coro::AnyEvent in Coro::Handle.
244 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
245 do not have this method (and don't need it either).
246 - speed up generic anyevent methods in Coro::Handle by using rouse
247 callbacks.
248 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
249 others. It also makes the debugger happier, as you can trace
250 through the idle threads now.
251 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
252 - eg/event was pretty broken.
253 - better 5.8.6 compatibility.
254
