126.513 Sat Jul 15 01:18:51 CEST 2017
13 - experimental 5.22 comaptibility changes (PadlistNAMES).
14 - removed attributes example and made sure the other examples
15 still work.
16 - fix some statevar types for newer perls, should be of no consequence.
17
186.512 Fri Jul 14 05:03:17 CEST 2017
19 - seems to pass test suite down till 5.8.9, so make this the
20 minimum requirement in Makefile.PL.
21 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
22 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
23 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
24 fortified longjmp variants in some libcs.
25 - re-try JIT allocation without PROT_EXEC, to hopefully improve
26 portability (still doesn't seem to work around broken selinux
27 mmap everywhere).
28 - speling fixes (Xavier Guimard).
29
306.511 Sun Jun 26 23:44:50 CEST 2016
31 - make it compile with threaded perls again.
32 - simplify and speed up __DIE__ and __WARN__ handling.
33
346.51 Sat Jun 25 20:57:20 CEST 2016
35 - 6.5 release didn't compile on most older perls due to
36 a logic error enabling experimental 5.24 code for all versions.
37 - since various broken or deficient patches float around
38 to work around the vtbl API breakage in perl, let's provide
39 our own workaround, which seems to be much less invasive
40 and more compatible than the approaches seen so far. YMMV.
41 - work around assertion failure in perl_destruct on 5.24
42 (analyzed by Dave Mitchell).
43
446.5 Wed Jun 22 22:23:50 CEST 2016
45 - swap_sv swapping order was not symmetrical, causing
46 wrong swaps when swap_sv was used multiple times on the
47 same sv in the same thread.
48 - swap_sv calls can now be undone by calling it again
49 with the same variables.
50 - swap_sv calls will now be undone in async_pool threads.
51 - split Coro::Semaphore::up/adjust into separate xs functions
52 for better error reporting, at slight codesize increase.
53 - (libcoro) arm assembly support, please test and report.
54 - adjust to PL_savestack changes in perl 5.24 (adapted from
55 the debian patch, which unfortunately gets it wrong).
56
576.49 Sat Oct 17 01:40:12 CEST 2015
58 - throwing an exception to a thread waiting in
59 Coro::Handle using Coro::EV did not stop the watchers,
60 causing the next call to fail (testcase by Martin Pritchard).
61 - bump minimum perl version to 5.10.
62
636.48 Sun Oct 4 19:03:51 CEST 2015
64 - fix memory leak when Coro::Handle uses Coro::EV internally
65 (testcase by Sten Sten).
66 - update code to libev 4 API (internally, Coro still used the
67 version 3 API calls).
68 - remove unused hv_sig.
69
706.47 Sat Jul 11 03:58:20 CEST 2015
71 - swap_svs - NVs can be in the SV head beginning with 5.20.
72
736.46 Tue Jun 30 14:36:30 CEST 2015
74 - restore portability to perls with windows fork emulation
75 (patch by Petr Písař).
76
776.45 Tue Jun 30 01:40:08 CEST 2015
78 - restore portability to perl 5.16 and below.
79
806.44 Tue Jun 30 00:41:54 CEST 2015
81 - avoid segfaulting (or worse) when tracing a canceled thread.
82 - the Event module silently broke it's public hook API, causing
83 failures on perls compiled with -Duselongdouble. Requiring
84 the latest version of Event because I don't know which release
85 changed this (it's not mentioned in the ChangeLog).
86 - allow xs level enterleave hooks via CoroAPI.
87
886.43 Thu Jun 4 15:38:14 CEST 2015
89 - use stability canary.
90 - port to stableperl-5.22.0-1.001.
91 - update libecb.
92
936.42 Wed Feb 11 20:29:52 CET 2015
94 - Coro::SemaphoreSet->try did not actually work (analyzed by
95 SATO Kentaro).
96 - upgrade libecb to be C11 compliant.
97
986.41 Sat Sep 6 22:08:46 CEST 2014
99 - restore portability to perl 5.8.x.
100 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
101 up some memory, but fixes "use feature" and similar modules
102 when used inside a Coro.
103 - allow zero as argument to Coro::Channel to mean the same thing
104 as no argument. this works with older versions as well,
105 but wasn't legal until now.
106 - slightly better c header file detection.
107
1086.39 Mon Jun 2 00:00:08 CEST 2014
109 - work around more incompatible changes in 5.20.
110
1116.38 Sun Jun 1 21:54:23 CEST 2014
112 - check that perl slots actually have enough space to hold
113 interpreter variables.
114 - untested port to perl 5.19 (64 bit tmps indices) (reported
115 by Andreas König).
116 - croak when cancel is called without a thread context.
117
1186.37 Tue Mar 4 13:27:33 CET 2014
119 - *sigh*, removed leftover debugging code from debugging a
120 perl bug, of all things.
121
1226.36 Tue Mar 4 07:11:59 CET 2014
123 - semaphores would not clear the destroy hook when interrupted
124 by ->throw, causing segfaults or worse.
125 - ->throw on a thread waiting for a semaphore did not acquire
126 the semaphore, but also didn't wake up other waiters,
127 possibly causing a deadlock.
128 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
129 to report a full stacktrace, which should help find out
130 where the actual call is.
131 - "atomically" destroy data in slf_destroy, because it is
132 the right thing to do, just in case.
133 - disable ecb.h libm dependency, to compile on ancient systems
134 or under adverse conditions.
135
1366.33 Mon Nov 18 11:26:27 CET 2013
137 - do not crash when freeing padlists with holes (in 5.18).
138 - tentative SVt_BIND 5.19 port/fix.
139
1406.32 Tue Nov 5 15:35:35 CET 2013
141 - use a new algorithm to derive padlists for perl 5.18. The old
142 one could lead to 0-pointer accesses inside perl (reported
143 by Darin McBride).
144
1456.31 Thu May 9 07:39:48 CEST 2013
146 - Coro::AIO requests would crash if the thread was ready'd
147 while the request was ongoing.
148
1496.29 Wed May 8 02:55:18 CEST 2013
150 - when an on_destroy handler destructs the coro currently being
151 destructed a perl scalar could be accessed after being freed,
152 likely causing a crash.
153
1546.28 Wed Mar 6 06:58:02 CET 2013
155 - clean remnants of existing __DIE__ and __WARN__ handlers so
156 they lose their magic and will not cause segfaults later
157 (testcase by Andrey Sagulin).
158 - improved Coro::State documentation a bit.
159 - Coro::Debug::command now flushes the output.
160 - add hack detection code for x32 abi, because the braindead slugs
161 who designed that made it look exactly like x86_64 without
162 providing proper compile time symbols to test for it. as a result,
163 this detection cannot work reliably.
164 - valgrind stack registering was broken.
165 - do not rely on Time::HiRes anymore in Coro::Debug.
166
1676.23 Fri Dec 7 23:36:37 CET 2012
168 - use experimental fiber implementation on native windows
169 perls.
170 - use sizeof (void *) as multiplication factor for stack sizes,
171 to accomodate the totally braindamaged microsoft 64 bit "os".
172 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
173 activeperl 5.16 crashes when PerlIO_define_layer is called due
174 to some bug in the perl dll, strawberry perl at least passes
175 the testsuite.
176 - implement Coro::Handle->peeraddr/host/port, for slightly
177 improved compatibility with LWP.
10 - implement 5.17 compatibility by almost blindly applying a 178 - implement 5.17 compatibility by almost blindly applying a
11 good-looking patch by Father Chrysostomos. 179 good-looking patch by Father Chrysostomos.

13 perls. 181 - libcoro version 3 "released".
14 - support magic values as timed_io_once args. 182 - support magic values as timed_io_once args.
15 - recommend AnyEvent 7+ or EV 4+, also require EV 183 - recommend AnyEvent 7+ or EV 4+, also require EV
16 version 4 or newer for Coro::EV. 184 version 4 or newer for Coro::EV.
