7 - improved Coro::State documentation a bit.
8 - Coro::Debug::command now flushes the output.

106.23 Fri Dec 7 23:36:37 CET 2012
11 - use experimental fiber implementation on native windows
12 perls.
13 - use sizeof (void *) as multiplication factor for stack sizes,
14 to accomodate the totally braindamaged microsoft 64 bit "os".
15 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
16 activeperl 5.16 crashes when PerlIO_define_layer is called due
17 to some bug in the perl dll, strawberry perl at least passes
18 the testsuite.
19 - implement Coro::Handle->peeraddr/host/port, for slightly
20 improved compatibility with LWP.
21 - implement 5.17 compatibility by almost blindly applying a
22 good-looking patch by Father Chrysostomos.
23 - move stack management functions into libcoro 3.
24 - libcoro version 3 "released".
25 - support magic values as timed_io_once args.
26 - recommend AnyEvent 7+ or EV 4+, also require EV
27 version 4 or newer for Coro::EV.
28
296.10 Tue Oct 9 01:14:27 CEST 2012
30 - updated ecb.h, it had a typo that caused it to not compile on many
31 big endian systems (reported by many people).
32 - disable memory fences in ecb.h to improve portability.
33
346.09 Sat Oct 6 23:25:02 CEST 2012
35 - Coro::EV I/O watchers were not interruptible by exceptions
36 (Coro::State::throw) (testcase by sten).
37 - ->throw now puts threads into the ready queue, as this seems to
38 be expected by existing code, and code that doesn't cope with spurious
39 wakeups needs fixing anyway.
40 - use fd -1 in mmap.
41 - cast I32 to int in error message printf.
42 - warn about broken so-called "hardened" kernels.
43
446.08 Fri Apr 13 12:05:47 CEST 2012
45 - be more aggressive about exiting like perl does - formerly,
46 exiting from the non-main thread would not execute END blocks.
47
486.07 Fri Nov 11 21:21:48 CET 2011
49 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
50 - update ecb.h.
51
526.06 Mon Aug 8 23:59:48 CEST 2011
53 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
54 backend, which is an order of magnitude slower. unfortunately, cygwins
55 pthread implementation isn't very complete either, so allocate the stack
56 twice just to be sure.
57 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
58 in its ithreaded perl - best recompile cygwin and use the 'w'indows
59 backend for much better performance. also disable ithreads for
60 even better performance...).
61
626.05 Thu Aug 4 21:36:36 CEST 2011
63 - blush, condvar values would not be propagated from send to recv anymore
64 (reported by Chip Salzenberg).
65 - use exponential increase for the readline buffer length in
66 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
67
686.04 Wed Aug 3 17:15:45 CEST 2011
69 - use even more efficient and more compatible condvars for
70 compatibility to AnyEvent 6.x :)
71 - more inconsequential ecb.h updates.
72
736.03 Wed Aug 3 11:41:30 CEST 2011
74 - change how Coro patches AnyEvent condvars for compatibility to
75 AnyEvent 6.x.
76 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
77 hasn't been included.
78
796.02 Wed Jul 13 04:35:19 CEST 2011
80 - "improve portability to Gentoo" - gentoo manages to put perl variables
81 in memory areas that are farther than 2gb apart, which the jit couldn't
82 handle and barfed. now it's just a bit slower on gentoo and similar
83 systems.
84
856.01 Sun Jul 3 12:31:14 CEST 2011
86 - workarounds are good, but the test for whether pthreads are used
87 was not good. thisone should be better.
88 - check differently whether gcc generates cfi instructions itself.
89
906.0 Wed Jun 29 19:43:35 CEST 2011
91 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
92 destroyed and cleaned up automatically (e.g. async { schedule }).
93 - implement a JIT compiler for part of the thread switch code,
94 which gives a 50% speed improvement on threaded perls, and
95 about 4% on non-thraeded perls (so threaded perls now finally
96 reach about half the speed of non-threaded perls).
97 - slightly modernise Coro::Intro, add section about rouse functions.
98 - avoid DEFSV and ERRSV, giving another 10% improvement
99 in thread switching.
100 - Coro::State->is_destroyed is now called is_zombie.
101 - implement a Coro->safe_cancel method that might fail, but
102 cancels in a "safer" way if it succeeds.
103 - add preliminary support for DEBUGGING perls.
104 - get rid of two hash-accesses when initialising a new Coro - this
105 speeds up coro creation by almost a factor of two.
106 - croak when a coro that is being cancelled tries to block
107 (e.g. while executing a guard block), instead of crashing or
108 deadlocking.
109 - use a more robust and also faster method to identify Coro::State
110 objects - speeds up everything a bit.
111 - implement Coro->cancel in XS for a 20% speed improvement, and to
112 be able to implement mutual cancellation.
113 - speed up context switches by a percent or two by more efficiently
114 allocating context stack entries.
115 - implement Coro->join and Coro->on_destroy in XS for a speedup and
116 a reduction in memory use.
117 - cancelling a coro while it itself is cancelling another coro is
118 now supported and working, instead of triggering an assertion.
119 - be a bit more crash-resistant when calling (buggy) on_destroy
120 callbacks (best effort).
121 - move on_destroy into the slf_frame, to allow extension slf
122 functions to have destructors.
123 - get rid if coro refcounting - simply crash in other interpreter
124 threads by nulling the pointers on clone.
125 - simplify warn/die hook handling when loading Coro - the convoluted
126 logic seems to be no longer neccessary.
127 - use libecb instead of our own home-grown gcc hacks.
128 - document alternatives to Coro::LWP. Please use them :)
129 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
130 sigaltstack. Really. wine suffers from it, erlang suffers from it,
131 and it's known since at least 2006.
132
1335.372 Wed Feb 23 06:14:30 CET 2011
134 - apparently mingw doesn't provide a working gettimeofday, try to
135 work around that by relying on Time::HiRes (indirectly brought to
136 my attention by Max Maischein).
137 - fix some portability issues when Time::HiRes was used.
138
1395.371 Mon Feb 21 14:36:08 CET 2011
140 - backport to windows process emulation code again.
141
1425.37 Sat Feb 19 07:49:44 CET 2011
143 - add a big "Coro thread life cycle" section to "man Coro".
144 - try a tentative workaround against the breakage that 5.13 has
145 introduced without depreciation period. sigh.
146 - no longer use Time::HiRes if gettimeofday is available, which
147 saves quite a lot of memory.
148
1495.36 Sun Feb 13 05:33:41 CET 2011
150 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
151 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
152 method call.
153 - undocument Coro::Timer::sleep and obsolete whole module.
154 - optimise Coro::Timer::timeout memory and cpu usage.
155 - slightly updated Coro::Intro for recent changes.
156 - do not initialise PL_dirty anymore.
157
1585.25 Thu Nov 11 01:08:39 CET 2010

10 working pthreads, but still broken ucontext/sigaltstack. 160 working pthreads, but still broken ucontext/sigaltstack.
161 - openbsd 4.8 finally got their act together, Coro works out of the box
162 with asm, setjmp and pthreads (no change, just informational).

125.24 Sat Oct 23 11:27:12 CEST 2010 1645.24 Sat Oct 23 11:27:12 CEST 2010
