12 - libcoro update: allow sharing of coro threads using the pthreads
13 backend among different pthreads, as is required by Coro::Multicore.
14 - always allow ->call and ->eval when the coro is the current coroutine. this
15 makes it possible, among other things, to call these on $Coro::main.
16 - minor code cleanups.
17
186.514 Thu Aug 31 18:25:31 CEST 2017
19 - safe_cancel no longer croaks when called on already-destroyed
20 thread, but instead "just works".
21
226.513 Sat Jul 15 01:18:51 CEST 2017
23 - experimental 5.22 comaptibility changes (PadlistNAMES).
24 - removed attributes example and made sure the other examples
25 still work.
26 - fix some statevar types for newer perls, should be of no consequence.
27
286.512 Fri Jul 14 05:03:17 CEST 2017
29 - seems to pass test suite down till 5.8.9, so make this the
30 minimum requirement in Makefile.PL.
31 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
32 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
33 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
34 fortified longjmp variants in some libcs.
35 - re-try JIT allocation without PROT_EXEC, to hopefully improve
36 portability (still doesn't seem to work around broken selinux
37 mmap everywhere).
38 - speling fixes (Xavier Guimard).
39
406.511 Sun Jun 26 23:44:50 CEST 2016
41 - make it compile with threaded perls again.
42 - simplify and speed up __DIE__ and __WARN__ handling.
43
446.51 Sat Jun 25 20:57:20 CEST 2016
45 - 6.5 release didn't compile on most older perls due to
46 a logic error enabling experimental 5.24 code for all versions.
47 - since various broken or deficient patches float around
48 to work around the vtbl API breakage in perl, let's provide
49 our own workaround, which seems to be much less invasive
50 and more compatible than the approaches seen so far. YMMV.
51 - work around assertion failure in perl_destruct on 5.24
52 (analyzed by Dave Mitchell).
53
546.5 Wed Jun 22 22:23:50 CEST 2016
55 - swap_sv swapping order was not symmetrical, causing
56 wrong swaps when swap_sv was used multiple times on the
57 same sv in the same thread.
58 - swap_sv calls can now be undone by calling it again
59 with the same variables.
60 - swap_sv calls will now be undone in async_pool threads.
61 - split Coro::Semaphore::up/adjust into separate xs functions
62 for better error reporting, at slight codesize increase.
63 - (libcoro) arm assembly support, please test and report.
64 - adjust to PL_savestack changes in perl 5.24 (adapted from
65 the debian patch, which unfortunately gets it wrong).
66
676.49 Sat Oct 17 01:40:12 CEST 2015
68 - throwing an exception to a thread waiting in
69 Coro::Handle using Coro::EV did not stop the watchers,
70 causing the next call to fail (testcase by Martin Pritchard).
71 - bump minimum perl version to 5.10.
72
736.48 Sun Oct 4 19:03:51 CEST 2015
74 - fix memory leak when Coro::Handle uses Coro::EV internally
75 (testcase by Sten Sten).
76 - update code to libev 4 API (internally, Coro still used the
77 version 3 API calls).
78 - remove unused hv_sig.
79
806.47 Sat Jul 11 03:58:20 CEST 2015
81 - swap_svs - NVs can be in the SV head beginning with 5.20.
82
836.46 Tue Jun 30 14:36:30 CEST 2015
84 - restore portability to perls with windows fork emulation
85 (patch by Petr Písař).
86
876.45 Tue Jun 30 01:40:08 CEST 2015
88 - restore portability to perl 5.16 and below.
89
906.44 Tue Jun 30 00:41:54 CEST 2015
91 - avoid segfaulting (or worse) when tracing a canceled thread.
92 - the Event module silently broke it's public hook API, causing
93 failures on perls compiled with -Duselongdouble. Requiring
94 the latest version of Event because I don't know which release
95 changed this (it's not mentioned in the ChangeLog).
96 - allow xs level enterleave hooks via CoroAPI.
97
986.43 Thu Jun 4 15:38:14 CEST 2015
99 - use stability canary.
100 - port to stableperl-5.22.0-1.001.
101 - update libecb.
102
1036.42 Wed Feb 11 20:29:52 CET 2015
104 - Coro::SemaphoreSet->try did not actually work (analyzed by
105 SATO Kentaro).
106 - upgrade libecb to be C11 compliant.
107
1086.41 Sat Sep 6 22:08:46 CEST 2014
109 - restore portability to perl 5.8.x.
110 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
111 up some memory, but fixes "use feature" and similar modules
112 when used inside a Coro.
113 - allow zero as argument to Coro::Channel to mean the same thing
114 as no argument. this works with older versions as well,
115 but wasn't legal until now.
116 - slightly better c header file detection.
117
1186.39 Mon Jun 2 00:00:08 CEST 2014
119 - work around more incompatible changes in 5.20.
120
1216.38 Sun Jun 1 21:54:23 CEST 2014
122 - check that perl slots actually have enough space to hold
123 interpreter variables.
124 - untested port to perl 5.19 (64 bit tmps indices) (reported
125 by Andreas König).
126 - croak when cancel is called without a thread context.
127
1286.37 Tue Mar 4 13:27:33 CET 2014
129 - *sigh*, removed leftover debugging code from debugging a
130 perl bug, of all things.
131
1326.36 Tue Mar 4 07:11:59 CET 2014
133 - semaphores would not clear the destroy hook when interrupted
134 by ->throw, causing segfaults or worse.
135 - ->throw on a thread waiting for a semaphore did not acquire
136 the semaphore, but also didn't wake up other waiters,
137 possibly causing a deadlock.
10 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess 138 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
11 to report a full stacktrace, which should help find out 139 to report a full stacktrace, which should help find out
12 where the actual call is. 140 where the actual call is.
141 - "atomically" destroy data in slf_destroy, because it is
142 the right thing to do, just in case.
143 - disable ecb.h libm dependency, to compile on ancient systems
144 or under adverse conditions.

129 which gives a 50% speed improvement on threaded perls, and 261 which gives a 50% speed improvement on threaded perls, and
130 about 4% on non-thraeded perls (so threaded perls now finally 262 about 4% on non-threaded perls (so threaded perls now finally
131 reach about half the speed of non-threaded perls). 263 reach about half the speed of non-threaded perls).
132 - slightly modernise Coro::Intro, add section about rouse functions. 264 - slightly modernise Coro::Intro, add section about rouse functions.
