8 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
9 destroyed and cleaned up automatically (e.g. async { schedule }).
10 - Coro::State->is_destroyed is now called is_zombie.
11 - implement a Coro->safe_cancel method that might fail, but
12 cancels in a "safer" way if it succeeds.
13 - get rid of two hash-accesses when initialising a new Coro - this
14 speeds up coro creation by almost a factor of two.
15 - croak when a coro that is being cancelled tries to block
16 (e.g. while executing a guard block), instead of crashing or
17 deadlocking.
18 - use a more robust and also faster method to identify Coro::State
19 objects - speeds up everything a bit.
20 - implement Coro->cancel in XS for a 20% speed improvement, and to
21 be able to implement mutual cancellation.
22 - speed up context switches by a percent or two by more efficiently
23 allocating context stack entries.
24 - implement Coro->join and Coro->on_destroy in XS for a speedup and
25 a reduction in memory use.
26 - cancelling a coro while it itself is cancelling another coro is
27 now supported and working, instead of triggering an assertion.
28 - be a bit more crash-resistant when calling (buggy) on_destroy
29 callbacks (best effort).
30 - move on_destroy into the slf_frame, to allow extension slf
31 functions to have destructors.
32 - get rid if coro refcounting - simply crash in other interpreter
33 threads by nulling the pointers on clone.
34 - simplify warn/die hook handling when loading Coro - the convoluted
35 logic seems to be no longer neccessary.
36
375.372 Wed Feb 23 06:14:30 CET 2011
38 - apparently mingw doesn't provide a working gettimeofday, try to
39 work around that by relying on Time::HiRes (indirectly brought to
40 my attention by Max Maischein).
41 - fix some portability issues when Time::HiRes was used.
42
435.371 Mon Feb 21 14:36:08 CET 2011
44 - backport to windows process emulation code again.
45
465.37 Sat Feb 19 07:49:44 CET 2011
47 - add a big "Coro thread life cycle" section to "man Coro".
48 - try a tentative workaround against the breakage that 5.13 has
49 introduced without depreciation period. sigh.
50 - no longer use Time::HiRes if gettimeofday is available, which
51 saves quite a lot of memory.
52
535.36 Sun Feb 13 05:33:41 CET 2011
54 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
55 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
56 method call.
57 - undocument Coro::Timer::sleep and obsolete whole module.
58 - optimise Coro::Timer::timeout memory and cpu usage.
59 - slightly updated Coro::Intro for recent changes.
60 - do not initialise PL_dirty anymore.
61
625.25 Thu Nov 11 01:08:39 CET 2010
63 - try a different approach on netbsd - netbsd 5 finally has marginally
64 working pthreads, but still broken ucontext/sigaltstack.
65 - openbsd 4.8 finally got their act together, Coro works out of the box
66 with asm, setjmp and pthreads (no change, just informational).
67
685.24 Sat Oct 23 11:27:12 CEST 2010
69 - port to the EV 4.0 API.
70 - work around bugs in mingw32, making strawberry perl work
71 out of the box.
72 - correctly modify Coro::AIO function prototypes
73 so that they reflect the "no optional parameters" rule.
74 - "ported" libcoro to C++.
75
765.23 Mon May 17 18:50:42 CEST 2010
77 - be more resistant to ordering changes when initialising
78 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
79 Waldorf).
80 - document that perl 5.12 deliberately removed support for cloning.
81
825.22 Wed Apr 14 03:55:35 CEST 2010
83 - correctly return udnef on errors in Coro::Handle::read/write
84 (testcase by Marc Mims).
85 - convert Coro::Util into a "perl compatibility wrapper" - the functions
86 are less useful now, but are drop-in replacements for existing
87 functions, listing better alternatives in the documentation. This also
88 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
89 with Coro::Util::inet_aton.
90 - do not override $Coro::idle unconditionally in Coro.pm, as other
91 modules could have provided their own idle coro already
92 (for exmaple, Coro::AnyEvent).
93 - fix Coro::Util::gethost* functions.
94 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
95
965.21 Wed Dec 16 07:19:51 CET 2009
97 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
98 together.
99 - add some examples on how to combine other event loops with Coro in
100 Coro::AnyEvent, and how to run it (and not to block). Seems to be
101 the most common source of confusion.
102 - try to catch people naively blocking in an event callback.
103 - work around the perl filehandle bug issue in conjunction with
104 older common::sense (as indirectly pointed out by ZSystem).
105 - clarify the "not from signal handlers" section.
106
1075.2 Sun Oct 4 14:54:24 CEST 2009
108 - Coro::Storable destroyed the prototypes of the functions it wrapped.
109 - export rouse_cb and rouse_wait by default now.
110 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
111 - new method $state->swap_sv.
112 - added section on "windows process emulation" to the manpage,
113 after a not-so-fruitful (nor-friendly) "discussion" with chip
114 salzenberg (discussion implies arguments, but his only arguments
115 were ad-hominems, one wonders why he started it in the first
116 place). I hope this explains it well enough for him to understand,
117 and maybe well enough for others to understand.
118 - use common::sense everywhere now.
119 - idle callbacks are no longer supported, use idle coros instead.
120 - print a thread listing when a deadlock is detected.
121
1225.17 Sat Aug 22 23:09:31 CEST 2009
123 - work around a bug in the perl debugger causing crashes
124 when running under the debugger by marking _pool_handler as nodebug.
125 - speed up Coro::async considerably.
126 - try some hacks to get netbsd to work "more often" - their broken
127 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
128 - convert Coro to AE 5.0 API.
129
1305.162 Tue Jul 28 04:04:03 CEST 2009
131 - perl 5.8.2 is now minimum requirement.
132 - skip t/19_handle.t on broken windows perls.
133
1345.161 Wed Jul 22 04:47:38 CEST 2009
135 - Coro::AnyEvent::poll could have a different prototype when EV was
136 used as backend (analyzed by Tatsuhiko Miyagawa).
11 - Coro::AnyEvent errornously initialised the event loop when loaded, 137 - Coro::AnyEvent errornously initialised the event loop when loaded,
12 not on demand. 138 not on demand.
139 - try to workaround rare */t/01_unblock.t failures.

145.16 Tue Jul 21 01:44:37 CEST 2009 1415.16 Tue Jul 21 01:44:37 CEST 2009
15 - Coro::AnyEvent failed to hook into the event loop 142 - Coro::AnyEvent failed to hook into the event loop
16 when no threads had been readied between detecting 143 when no threads had been readied between detecting
17 the event loop and actually running it. 144 the event loop and actually running it.
