8TODO: in_eval, PL_tained
9 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
10 destroyed and cleaned up automatically (e.g. async { schedule }).
11 - implement a JIT compiler for part of the thread switch code,
12 which gives a 50% speed improvement on threaded perls, and
13 about 4% on non-thraeded perls (so threaded perls now finally
14 reach about half the speed of non-threaded perls).
15 - avoid DEFSV and ERRSV, giving another 10% improvement
16 in thread switching.
17 - Coro::State->is_destroyed is now called is_zombie.
18 - implement a Coro->safe_cancel method that might fail, but
19 cancels in a "safer" way if it succeeds.
20 - get rid of two hash-accesses when initialising a new Coro - this
21 speeds up coro creation by almost a factor of two.
22 - croak when a coro that is being cancelled tries to block
23 (e.g. while executing a guard block), instead of crashing or
24 deadlocking.
25 - use a more robust and also faster method to identify Coro::State
26 objects - speeds up everything a bit.
27 - implement Coro->cancel in XS for a 20% speed improvement, and to
28 be able to implement mutual cancellation.
29 - speed up context switches by a percent or two by more efficiently
30 allocating context stack entries.
31 - implement Coro->join and Coro->on_destroy in XS for a speedup and
32 a reduction in memory use.
33 - cancelling a coro while it itself is cancelling another coro is
34 now supported and working, instead of triggering an assertion.
35 - be a bit more crash-resistant when calling (buggy) on_destroy
36 callbacks (best effort).
37 - move on_destroy into the slf_frame, to allow extension slf
38 functions to have destructors.
39 - get rid if coro refcounting - simply crash in other interpreter
40 threads by nulling the pointers on clone.
41 - simplify warn/die hook handling when loading Coro - the convoluted
42 logic seems to be no longer neccessary.
43 - use libecb instead of our own home-grown gcc hacks.
44 - document alternatives to Coro::LWP. Please use them :)
45 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
46 sigaltstack. Really. wine suffers from it, erlang suffers from it,
47 and its' known since at least 2006.
48
495.372 Wed Feb 23 06:14:30 CET 2011
50 - apparently mingw doesn't provide a working gettimeofday, try to
51 work around that by relying on Time::HiRes (indirectly brought to
52 my attention by Max Maischein).
53 - fix some portability issues when Time::HiRes was used.
54
555.371 Mon Feb 21 14:36:08 CET 2011
56 - backport to windows process emulation code again.
57
585.37 Sat Feb 19 07:49:44 CET 2011
59 - add a big "Coro thread life cycle" section to "man Coro".
60 - try a tentative workaround against the breakage that 5.13 has
61 introduced without depreciation period. sigh.
62 - no longer use Time::HiRes if gettimeofday is available, which
63 saves quite a lot of memory.
64
655.36 Sun Feb 13 05:33:41 CET 2011
66 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
67 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
68 method call.
69 - undocument Coro::Timer::sleep and obsolete whole module.
70 - optimise Coro::Timer::timeout memory and cpu usage.
71 - slightly updated Coro::Intro for recent changes.
72 - do not initialise PL_dirty anymore.
73
745.25 Thu Nov 11 01:08:39 CET 2010
75 - try a different approach on netbsd - netbsd 5 finally has marginally
76 working pthreads, but still broken ucontext/sigaltstack.
77 - openbsd 4.8 finally got their act together, Coro works out of the box
78 with asm, setjmp and pthreads (no change, just informational).
79
805.24 Sat Oct 23 11:27:12 CEST 2010
81 - port to the EV 4.0 API.
82 - work around bugs in mingw32, making strawberry perl work
83 out of the box.
84 - correctly modify Coro::AIO function prototypes
85 so that they reflect the "no optional parameters" rule.
86 - "ported" libcoro to C++.
87
885.23 Mon May 17 18:50:42 CEST 2010
89 - be more resistant to ordering changes when initialising
90 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
91 Waldorf).
92 - document that perl 5.12 deliberately removed support for cloning.
93
945.22 Wed Apr 14 03:55:35 CEST 2010
95 - correctly return udnef on errors in Coro::Handle::read/write
96 (testcase by Marc Mims).
97 - convert Coro::Util into a "perl compatibility wrapper" - the functions
98 are less useful now, but are drop-in replacements for existing
99 functions, listing better alternatives in the documentation. This also
100 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
101 with Coro::Util::inet_aton.
102 - do not override $Coro::idle unconditionally in Coro.pm, as other
103 modules could have provided their own idle coro already
104 (for exmaple, Coro::AnyEvent).
105 - fix Coro::Util::gethost* functions.
106 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
107
1085.21 Wed Dec 16 07:19:51 CET 2009
109 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
110 together.
111 - add some examples on how to combine other event loops with Coro in
112 Coro::AnyEvent, and how to run it (and not to block). Seems to be
113 the most common source of confusion.
114 - try to catch people naively blocking in an event callback.
115 - work around the perl filehandle bug issue in conjunction with
116 older common::sense (as indirectly pointed out by ZSystem).
117 - clarify the "not from signal handlers" section.
118
1195.2 Sun Oct 4 14:54:24 CEST 2009
120 - Coro::Storable destroyed the prototypes of the functions it wrapped.
121 - export rouse_cb and rouse_wait by default now.
122 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
123 - new method $state->swap_sv.
124 - added section on "windows process emulation" to the manpage,
125 after a not-so-fruitful (nor-friendly) "discussion" with chip
126 salzenberg (discussion implies arguments, but his only arguments
127 were ad-hominems, one wonders why he started it in the first
128 place). I hope this explains it well enough for him to understand,
129 and maybe well enough for others to understand.
130 - use common::sense everywhere now.
131 - idle callbacks are no longer supported, use idle coros instead.
132 - print a thread listing when a deadlock is detected.
133
1345.17 Sat Aug 22 23:09:31 CEST 2009
135 - work around a bug in the perl debugger causing crashes
136 when running under the debugger by marking _pool_handler as nodebug.
137 - speed up Coro::async considerably.
138 - try some hacks to get netbsd to work "more often" - their broken
139 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
140 - convert Coro to AE 5.0 API.
141
1425.162 Tue Jul 28 04:04:03 CEST 2009
143 - perl 5.8.2 is now minimum requirement.
144 - skip t/19_handle.t on broken windows perls.
145
1465.161 Wed Jul 22 04:47:38 CEST 2009
147 - Coro::AnyEvent::poll could have a different prototype when EV was
148 used as backend (analyzed by Tatsuhiko Miyagawa).
149 - Coro::AnyEvent errornously initialised the event loop when loaded,
150 not on demand.
151 - try to workaround rare */t/01_unblock.t failures.
152
1535.16 Tue Jul 21 01:44:37 CEST 2009
154 - Coro::AnyEvent failed to hook into the event loop
155 when no threads had been readied between detecting
156 the event loop and actually running it.
157 - considerably speed up Coro::Select by taking avdantage
158 of AnyEvent > 4.8 and some other optimisations.
159 - implement paragraph readline mode in Coro::Handle
160 (based on patches by Zsbán Ambrus).
161 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
162 and analyzed by Yasuhiro MATSUMOTO).
163 - clarified libcoro license and copyright.
164 - someone stole my EXTRA_META!!!
165 - implement Coro::Select::patch_pp_sselect and it's brother,
166 for hardcode select overriding.
167
1685.151 Mon Jul 6 05:41:57 CEST 2009
169 - backport to windows process emulation code again (patch by
170 Yasuhiro MATSUMOTO).
171 - slightly update Coro::MakeMaker.
172
1735.15 Tue Jun 30 10:28:06 CEST 2009
174 - deprecate Coro::Socket, document how to get ipv6 support via
175 AnyEvent::Socket instead.
176 - implement signal->wait ($cb) interface, similar to semaphores.
177 - work around SvOK not supporting getmagic, so we have to getmagic
178 to test for undef :/ (reported by Matthias Waldorf).
179 - load Coro::AnyEvent in all modules using AnyEvent.
180 - work around perl corrupting our internal data structures,
181 reported by Tokuhiro Matsuno.
182 - enable per-coroutine real and cpu time gathering
183 (Coro::State::enable_times).
184
1855.14 Wed Jun 24 01:37:48 CEST 2009
186 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
187 as this seems to have been a difficult concept (poll, sleep, idle,
188 idle_upto).
189 - add Coro::AnyEvent::readable/writable functions.
190 - clarify Coro::EV/Event/AnyEvent manpages.
191 - free per-thread global scalars in the thread calling ->cancel, to
192 avoid crashes when $_, $@ etc., are magical but some of those
193 had already been freed.
194 - "unexperimentalise" the callback interface for Coro::Semaphore.
195 - speed up ready queue management/context switching by using a linked
196 list instead of an array (~5-10%).
197 - implement "watch" command in Coro::Debug shells.
198 - for fun, implement time-slicing as an example in the manpage.
199 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
200 Coro::Event, use the normal AnyEvent handling instead of dieing
201 (the same is true for Coro::Handle).
202 - properly document Coro::EV::timed_io_once.
203 - avoid unneccessary ->cancel calls in Coro::Handle.
204 - maybe make it work on mingw32 with win32 backend
205 (based on patch by Yasuhiro Matsumoto).
206
2075.132 Fri May 29 09:00:39 CEST 2009
208 - do not keep a reference to the argument itself in
209 Coro::Semaphore::guard, as it could change later.
210 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
211 should support a prepare callback.
212
2135.131 Mon Mar 16 23:20:37 CET 2009
214 - implement and document Coro->suspend, Coro->resume.
215 - fix Coro::Select implementation to not (often) close
216 the passed file descriptors (testcase provided by pippijn).
217
2185.13 Mon Dec 15 21:51:42 CET 2008
9 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave). 219 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
10 - don't set diehook to C<undef> but instead to NULL, to avoid 220 - don't set diehook to C<undef> but instead to NULL, to avoid
