9 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
10 destroyed and cleaned up automatically (e.g. async { schedule }).
11 - Coro::State->is_destroyed is now called is_zombie.
12 - implement a Coro->safe_cancel method that might fail, but
13 cancels in a "safer" way if it succeeds.
14 - get rid of two hash-accesses when initialising a new Coro - this
15 speeds up coro creation by almost a factor of two.
16 - croak when a coro that is being cancelled tries to block
17 (e.g. while executing a guard block), instead of crashing or
18 deadlocking.
19 - use a more robust and also faster method to identify Coro::State
20 objects - speeds up everything a bit.
21 - implement Coro->cancel in XS for a 20% speed improvement, and to
22 be able to implement mutual cancellation.
23 - speed up context switches by a percent or two by more efficiently
24 allocating context stack entries.
25 - implement Coro->join and Coro->on_destroy in XS for a speedup and
26 a reduction in memory use.
27 - cancelling a coro while it itself is cancelling another coro is
28 now supported and working, instead of triggering an assertion.
29 - be a bit more crash-resistant when calling (buggy) on_destroy
30 callbacks (best effort).
31 - move on_destroy into the slf_frame, to allow extension slf
32 functions to have destructors.
33 - get rid if coro refcounting - simply crash in other interpreter
34 threads by nulling the pointers on clone.
35 - simplify warn/die hook handling when loading Coro - the convoluted
36 logic seems to be no longer neccessary.
37 - use libecb instead of our own home-grown gcc hacks.
38
395.372 Wed Feb 23 06:14:30 CET 2011
40 - apparently mingw doesn't provide a working gettimeofday, try to
41 work around that by relying on Time::HiRes (indirectly brought to
42 my attention by Max Maischein).
43 - fix some portability issues when Time::HiRes was used.
44
455.371 Mon Feb 21 14:36:08 CET 2011
46 - backport to windows process emulation code again.
47
485.37 Sat Feb 19 07:49:44 CET 2011
49 - add a big "Coro thread life cycle" section to "man Coro".
50 - try a tentative workaround against the breakage that 5.13 has
51 introduced without depreciation period. sigh.
52 - no longer use Time::HiRes if gettimeofday is available, which
53 saves quite a lot of memory.
54
555.36 Sun Feb 13 05:33:41 CET 2011
56 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
57 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
58 method call.
59 - undocument Coro::Timer::sleep and obsolete whole module.
60 - optimise Coro::Timer::timeout memory and cpu usage.
61 - slightly updated Coro::Intro for recent changes.
62 - do not initialise PL_dirty anymore.
63
645.25 Thu Nov 11 01:08:39 CET 2010
65 - try a different approach on netbsd - netbsd 5 finally has marginally
66 working pthreads, but still broken ucontext/sigaltstack.
67 - openbsd 4.8 finally got their act together, Coro works out of the box
68 with asm, setjmp and pthreads (no change, just informational).
69
705.24 Sat Oct 23 11:27:12 CEST 2010
71 - port to the EV 4.0 API.
72 - work around bugs in mingw32, making strawberry perl work
73 out of the box.
74 - correctly modify Coro::AIO function prototypes
75 so that they reflect the "no optional parameters" rule.
76 - "ported" libcoro to C++.
77
785.23 Mon May 17 18:50:42 CEST 2010
79 - be more resistant to ordering changes when initialising
80 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
81 Waldorf).
82 - document that perl 5.12 deliberately removed support for cloning.
83
845.22 Wed Apr 14 03:55:35 CEST 2010
85 - correctly return udnef on errors in Coro::Handle::read/write
86 (testcase by Marc Mims).
87 - convert Coro::Util into a "perl compatibility wrapper" - the functions
88 are less useful now, but are drop-in replacements for existing
89 functions, listing better alternatives in the documentation. This also
90 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
91 with Coro::Util::inet_aton.
92 - do not override $Coro::idle unconditionally in Coro.pm, as other
93 modules could have provided their own idle coro already
94 (for exmaple, Coro::AnyEvent).
95 - fix Coro::Util::gethost* functions.
96 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
97
985.21 Wed Dec 16 07:19:51 CET 2009
99 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
100 together.
101 - add some examples on how to combine other event loops with Coro in
102 Coro::AnyEvent, and how to run it (and not to block). Seems to be
103 the most common source of confusion.
104 - try to catch people naively blocking in an event callback.
105 - work around the perl filehandle bug issue in conjunction with
106 older common::sense (as indirectly pointed out by ZSystem).
107 - clarify the "not from signal handlers" section.
108
1095.2 Sun Oct 4 14:54:24 CEST 2009
110 - Coro::Storable destroyed the prototypes of the functions it wrapped.
111 - export rouse_cb and rouse_wait by default now.
112 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
113 - new method $state->swap_sv.
114 - added section on "windows process emulation" to the manpage,
115 after a not-so-fruitful (nor-friendly) "discussion" with chip
116 salzenberg (discussion implies arguments, but his only arguments
117 were ad-hominems, one wonders why he started it in the first
118 place). I hope this explains it well enough for him to understand,
119 and maybe well enough for others to understand.
120 - use common::sense everywhere now.
121 - idle callbacks are no longer supported, use idle coros instead.
122 - print a thread listing when a deadlock is detected.
123
1245.17 Sat Aug 22 23:09:31 CEST 2009
125 - work around a bug in the perl debugger causing crashes
126 when running under the debugger by marking _pool_handler as nodebug.
127 - speed up Coro::async considerably.
128 - try some hacks to get netbsd to work "more often" - their broken
129 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
130 - convert Coro to AE 5.0 API.
131
1325.162 Tue Jul 28 04:04:03 CEST 2009
133 - perl 5.8.2 is now minimum requirement.
134 - skip t/19_handle.t on broken windows perls.
135
1365.161 Wed Jul 22 04:47:38 CEST 2009
137 - Coro::AnyEvent::poll could have a different prototype when EV was
138 used as backend (analyzed by Tatsuhiko Miyagawa).
139 - Coro::AnyEvent errornously initialised the event loop when loaded,
140 not on demand.
141 - try to workaround rare */t/01_unblock.t failures.
142
1435.16 Tue Jul 21 01:44:37 CEST 2009
144 - Coro::AnyEvent failed to hook into the event loop
145 when no threads had been readied between detecting
146 the event loop and actually running it.
147 - considerably speed up Coro::Select by taking avdantage
148 of AnyEvent > 4.8 and some other optimisations.
149 - implement paragraph readline mode in Coro::Handle
150 (based on patches by Zsbán Ambrus).
151 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
152 and analyzed by Yasuhiro MATSUMOTO).
153 - clarified libcoro license and copyright.
154 - someone stole my EXTRA_META!!!
155 - implement Coro::Select::patch_pp_sselect and it's brother,
156 for hardcode select overriding.
157
1585.151 Mon Jul 6 05:41:57 CEST 2009
159 - backport to windows process emulation code again (patch by
160 Yasuhiro MATSUMOTO).
161 - slightly update Coro::MakeMaker.
162
1635.15 Tue Jun 30 10:28:06 CEST 2009
164 - deprecate Coro::Socket, document how to get ipv6 support via
165 AnyEvent::Socket instead.
166 - implement signal->wait ($cb) interface, similar to semaphores.
167 - work around SvOK not supporting getmagic, so we have to getmagic
168 to test for undef :/ (reported by Matthias Waldorf).
169 - load Coro::AnyEvent in all modules using AnyEvent.
170 - work around perl corrupting our internal data structures,
171 reported by Tokuhiro Matsuno.
172 - enable per-coroutine real and cpu time gathering
173 (Coro::State::enable_times).
174
1755.14 Wed Jun 24 01:37:48 CEST 2009
176 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
177 as this seems to have been a difficult concept (poll, sleep, idle,
178 idle_upto).
179 - add Coro::AnyEvent::readable/writable functions.
180 - clarify Coro::EV/Event/AnyEvent manpages.
181 - free per-thread global scalars in the thread calling ->cancel, to
182 avoid crashes when $_, $@ etc., are magical but some of those
183 had already been freed.
184 - "unexperimentalise" the callback interface for Coro::Semaphore.
185 - speed up ready queue management/context switching by using a linked
186 list instead of an array (~5-10%).
187 - implement "watch" command in Coro::Debug shells.
188 - for fun, implement time-slicing as an example in the manpage.
189 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
190 Coro::Event, use the normal AnyEvent handling instead of dieing
191 (the same is true for Coro::Handle).
192 - properly document Coro::EV::timed_io_once.
193 - avoid unneccessary ->cancel calls in Coro::Handle.
194 - maybe make it work on mingw32 with win32 backend
195 (based on patch by Yasuhiro Matsumoto).
196
1975.132 Fri May 29 09:00:39 CEST 2009
198 - do not keep a reference to the argument itself in
199 Coro::Semaphore::guard, as it could change later.
200 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
201 should support a prepare callback.
202
2035.131 Mon Mar 16 23:20:37 CET 2009
204 - implement and document Coro->suspend, Coro->resume.
205 - fix Coro::Select implementation to not (often) close
206 the passed file descriptors (testcase provided by pippijn).
207
2085.13 Mon Dec 15 21:51:42 CET 2008
