8new -> ready 7TODO:mg_virtual check
9new -> canceled 8TODO:detah on refcnt
10ready -> running 9TODO:slf_xx_yy=>slf_yy_xx
11ready -> canceled 10 - croak when a coro that is being cancelled tries to block
12running -> ready 11 (e.g. while executing a guard block), instead of crashing or
13running -> blocked 12 deadlocking.
14running -> canceled 13 - use a more robust and also faster method to identify Coro::State
15blocked -> ready 14 objects - speeds up everything a bit.
16blocked -> canceled 15 - implement a Coro->safe_cancel method that might fail, but
16 cancels in a "safer" way if it succeeds.
17 - implement Coro->cancel in XS for a 20% speed improvement, and to
18 be able to implement mutual cancellation.
19 - speed up context switches by a percent or two by more efficiently
20 allocating context stack entries.
21 - implement Coro->join and Coro->on_destroy in XS for a speedup and
22 a reduction in memory use.
23 - cancelling a coro while it itself is cancelling another coro is
24 now supported and working, instead of triggering an assertion.
25 - be a bit more crash-resistant when calling (buggy) on_destroy
26 callbacks (best effort).
27 - move on_destroy into the slf_frame, to allow extension slf
28 functions to have destructors.
29 - get rid if coro refcounting - simply crash in other interpreter
30 threads by nulling the pointers on clone.

185.13 325.372 Wed Feb 23 06:14:30 CET 2011
33 - apparently mingw doesn't provide a working gettimeofday, try to
34 work around that by relying on Time::HiRes (indirectly brought to
35 my attention by Max Maischein).
36 - fix some portability issues when Time::HiRes was used.
37
385.371 Mon Feb 21 14:36:08 CET 2011
39 - backport to windows process emulation code again.
40
415.37 Sat Feb 19 07:49:44 CET 2011
42 - add a big "Coro thread life cycle" section to "man Coro".
43 - try a tentative workaround against the breakage that 5.13 has
44 introduced without depreciation period. sigh.
45 - no longer use Time::HiRes if gettimeofday is available, which
46 saves quite a lot of memory.
47
485.36 Sun Feb 13 05:33:41 CET 2011
49 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
50 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
51 method call.
52 - undocument Coro::Timer::sleep and obsolete whole module.
53 - optimise Coro::Timer::timeout memory and cpu usage.
54 - slightly updated Coro::Intro for recent changes.
55 - do not initialise PL_dirty anymore.
56
575.25 Thu Nov 11 01:08:39 CET 2010
58 - try a different approach on netbsd - netbsd 5 finally has marginally
59 working pthreads, but still broken ucontext/sigaltstack.
60 - openbsd 4.8 finally got their act together, Coro works out of the box
61 with asm, setjmp and pthreads (no change, just informational).
62
635.24 Sat Oct 23 11:27:12 CEST 2010
64 - port to the EV 4.0 API.
65 - work around bugs in mingw32, making strawberry perl work
66 out of the box.
67 - correctly modify Coro::AIO function prototypes
68 so that they reflect the "no optional parameters" rule.
69 - "ported" libcoro to C++.
70
715.23 Mon May 17 18:50:42 CEST 2010
72 - be more resistant to ordering changes when initialising
73 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
74 Waldorf).
75 - document that perl 5.12 deliberately removed support for cloning.
76
775.22 Wed Apr 14 03:55:35 CEST 2010
78 - correctly return udnef on errors in Coro::Handle::read/write
79 (testcase by Marc Mims).
80 - convert Coro::Util into a "perl compatibility wrapper" - the functions
81 are less useful now, but are drop-in replacements for existing
82 functions, listing better alternatives in the documentation. This also
83 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
84 with Coro::Util::inet_aton.
85 - do not override $Coro::idle unconditionally in Coro.pm, as other
86 modules could have provided their own idle coro already
87 (for exmaple, Coro::AnyEvent).
88 - fix Coro::Util::gethost* functions.
89 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
90
915.21 Wed Dec 16 07:19:51 CET 2009
92 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
93 together.
94 - add some examples on how to combine other event loops with Coro in
95 Coro::AnyEvent, and how to run it (and not to block). Seems to be
96 the most common source of confusion.
97 - try to catch people naively blocking in an event callback.
98 - work around the perl filehandle bug issue in conjunction with
99 older common::sense (as indirectly pointed out by ZSystem).
100 - clarify the "not from signal handlers" section.
101
1025.2 Sun Oct 4 14:54:24 CEST 2009
103 - Coro::Storable destroyed the prototypes of the functions it wrapped.
104 - export rouse_cb and rouse_wait by default now.
105 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
106 - new method $state->swap_sv.
107 - added section on "windows process emulation" to the manpage,
108 after a not-so-fruitful (nor-friendly) "discussion" with chip
109 salzenberg (discussion implies arguments, but his only arguments
110 were ad-hominems, one wonders why he started it in the first
111 place). I hope this explains it well enough for him to understand,
112 and maybe well enough for others to understand.
113 - use common::sense everywhere now.
114 - idle callbacks are no longer supported, use idle coros instead.
115 - print a thread listing when a deadlock is detected.
116
1175.17 Sat Aug 22 23:09:31 CEST 2009
118 - work around a bug in the perl debugger causing crashes
119 when running under the debugger by marking _pool_handler as nodebug.
120 - speed up Coro::async considerably.
121 - try some hacks to get netbsd to work "more often" - their broken
122 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
123 - convert Coro to AE 5.0 API.
124
1255.162 Tue Jul 28 04:04:03 CEST 2009
126 - perl 5.8.2 is now minimum requirement.
127 - skip t/19_handle.t on broken windows perls.
128
1295.161 Wed Jul 22 04:47:38 CEST 2009
130 - Coro::AnyEvent::poll could have a different prototype when EV was
131 used as backend (analyzed by Tatsuhiko Miyagawa).
132 - Coro::AnyEvent errornously initialised the event loop when loaded,
133 not on demand.
134 - try to workaround rare */t/01_unblock.t failures.
135
1365.16 Tue Jul 21 01:44:37 CEST 2009
137 - Coro::AnyEvent failed to hook into the event loop
138 when no threads had been readied between detecting
139 the event loop and actually running it.
140 - considerably speed up Coro::Select by taking avdantage
141 of AnyEvent > 4.8 and some other optimisations.
142 - implement paragraph readline mode in Coro::Handle
143 (based on patches by Zsbán Ambrus).
144 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
145 and analyzed by Yasuhiro MATSUMOTO).
146 - clarified libcoro license and copyright.
147 - someone stole my EXTRA_META!!!
148 - implement Coro::Select::patch_pp_sselect and it's brother,
149 for hardcode select overriding.
150
1515.151 Mon Jul 6 05:41:57 CEST 2009
152 - backport to windows process emulation code again (patch by
153 Yasuhiro MATSUMOTO).
154 - slightly update Coro::MakeMaker.
155
1565.15 Tue Jun 30 10:28:06 CEST 2009
157 - deprecate Coro::Socket, document how to get ipv6 support via
158 AnyEvent::Socket instead.
159 - implement signal->wait ($cb) interface, similar to semaphores.
160 - work around SvOK not supporting getmagic, so we have to getmagic
161 to test for undef :/ (reported by Matthias Waldorf).
162 - load Coro::AnyEvent in all modules using AnyEvent.
163 - work around perl corrupting our internal data structures,
164 reported by Tokuhiro Matsuno.
165 - enable per-coroutine real and cpu time gathering
166 (Coro::State::enable_times).
167
1685.14 Wed Jun 24 01:37:48 CEST 2009
169 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
170 as this seems to have been a difficult concept (poll, sleep, idle,
171 idle_upto).
172 - add Coro::AnyEvent::readable/writable functions.
173 - clarify Coro::EV/Event/AnyEvent manpages.
174 - free per-thread global scalars in the thread calling ->cancel, to
175 avoid crashes when $_, $@ etc., are magical but some of those
176 had already been freed.
177 - "unexperimentalise" the callback interface for Coro::Semaphore.
178 - speed up ready queue management/context switching by using a linked
179 list instead of an array (~5-10%).
180 - implement "watch" command in Coro::Debug shells.
181 - for fun, implement time-slicing as an example in the manpage.
182 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
183 Coro::Event, use the normal AnyEvent handling instead of dieing
184 (the same is true for Coro::Handle).
185 - properly document Coro::EV::timed_io_once.
186 - avoid unneccessary ->cancel calls in Coro::Handle.
187 - maybe make it work on mingw32 with win32 backend
188 (based on patch by Yasuhiro Matsumoto).
189
1905.132 Fri May 29 09:00:39 CEST 2009
191 - do not keep a reference to the argument itself in
192 Coro::Semaphore::guard, as it could change later.
193 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
194 should support a prepare callback.
195
1965.131 Mon Mar 16 23:20:37 CET 2009
197 - implement and document Coro->suspend, Coro->resume.
198 - fix Coro::Select implementation to not (often) close
199 the passed file descriptors (testcase provided by pippijn).
200
2015.13 Mon Dec 15 21:51:42 CET 2008
202 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
19 - don't set diehook to C<undef> but instead to NULL, to avoid 203 - don't set diehook to C<undef> but instead to NULL, to avoid
20 spurious warnings. 204 spurious warnings.
21 - fix a lot of bugs in Coro::SemaphoreSet. 205 - fix a lot of bugs in Coro::SemaphoreSet.
22 - Coro::SemaphoreSet will less often create a semaphore needlessly. 206 - Coro::SemaphoreSet will less often create a semaphore needlessly.
23 - add Coro::SemaphoreSet::count and wait methods. 207 - add Coro::SemaphoreSet::count and wait methods.
24 - take advantage of the new Guard module. 208 - take advantage of the new Guard module.
25 - deprecate Coro::guard. 209 - deprecate Coro::guard.
26 - try to fix the dreaded 01_unblock tests once more. I hate it when 210 - try to fix the dreaded 01_unblock tests once more. I hate it when
27 testsuites need more fixing than the code they are supposed to test. 211 testsuites need more fixing than the code they are supposed to test.
212 - croak in more cases when a required callback isn't resolvable.
213 - fix some minor issues in Coro::State->call/eval.
214 - use current coroutine context instead of a temporary one
215 when temporarily switching to another coroutine.
216 - do not call C-level on_destroy handlers during global destruction,
217 to avoid needless segfaults.
