8 10
11 - the autogenerated prototypes of Coro::AIO now add ";" at the end
12 to avoid generating named unary operators and messing up parsing
13 (mostly affects aio_mlockall 4 | 8 which was parsed as
14 (aio_mlockall 4) | 8).
15 - do not use a prototype for select in Coro::Select, as CORE::select also
16 doesn't have one.
17
186.52 Tue Aug 14 18:49:43 CEST 2018
19 - libcoro update: allow sharing of coro threads using the pthreads
20 backend among different pthreads, as is required by Coro::Multicore.
21 - always allow ->call and ->eval when the coro is the current coroutine. this
22 makes it possible, among other things, to call these on $Coro::main.
23 - minor code cleanups.
24
256.514 Thu Aug 31 18:25:31 CEST 2017
26 - safe_cancel no longer croaks when called on already-destroyed
27 thread, but instead "just works".
28
296.513 Sat Jul 15 01:18:51 CEST 2017
30 - experimental 5.22 comaptibility changes (PadlistNAMES).
31 - removed attributes example and made sure the other examples
32 still work.
33 - fix some statevar types for newer perls, should be of no consequence.
34
356.512 Fri Jul 14 05:03:17 CEST 2017
36 - seems to pass test suite down till 5.8.9, so make this the
37 minimum requirement in Makefile.PL.
38 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
39 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
40 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
41 fortified longjmp variants in some libcs.
42 - re-try JIT allocation without PROT_EXEC, to hopefully improve
43 portability (still doesn't seem to work around broken selinux
44 mmap everywhere).
45 - speling fixes (Xavier Guimard).
46
476.511 Sun Jun 26 23:44:50 CEST 2016
48 - make it compile with threaded perls again.
49 - simplify and speed up __DIE__ and __WARN__ handling.
50
516.51 Sat Jun 25 20:57:20 CEST 2016
52 - 6.5 release didn't compile on most older perls due to
53 a logic error enabling experimental 5.24 code for all versions.
54 - since various broken or deficient patches float around
55 to work around the vtbl API breakage in perl, let's provide
56 our own workaround, which seems to be much less invasive
57 and more compatible than the approaches seen so far. YMMV.
58 - work around assertion failure in perl_destruct on 5.24
59 (analyzed by Dave Mitchell).
60
616.5 Wed Jun 22 22:23:50 CEST 2016
62 - swap_sv swapping order was not symmetrical, causing
63 wrong swaps when swap_sv was used multiple times on the
64 same sv in the same thread.
65 - swap_sv calls can now be undone by calling it again
66 with the same variables.
67 - swap_sv calls will now be undone in async_pool threads.
68 - split Coro::Semaphore::up/adjust into separate xs functions
69 for better error reporting, at slight codesize increase.
70 - (libcoro) arm assembly support, please test and report.
71 - adjust to PL_savestack changes in perl 5.24 (adapted from
72 the debian patch, which unfortunately gets it wrong).
73
746.49 Sat Oct 17 01:40:12 CEST 2015
75 - throwing an exception to a thread waiting in
76 Coro::Handle using Coro::EV did not stop the watchers,
77 causing the next call to fail (testcase by Martin Pritchard).
78 - bump minimum perl version to 5.10.
79
806.48 Sun Oct 4 19:03:51 CEST 2015
81 - fix memory leak when Coro::Handle uses Coro::EV internally
82 (testcase by Sten Sten).
83 - update code to libev 4 API (internally, Coro still used the
84 version 3 API calls).
85 - remove unused hv_sig.
86
876.47 Sat Jul 11 03:58:20 CEST 2015
88 - swap_svs - NVs can be in the SV head beginning with 5.20.
89
906.46 Tue Jun 30 14:36:30 CEST 2015
91 - restore portability to perls with windows fork emulation
92 (patch by Petr Písař).
93
946.45 Tue Jun 30 01:40:08 CEST 2015
95 - restore portability to perl 5.16 and below.
96
976.44 Tue Jun 30 00:41:54 CEST 2015
98 - avoid segfaulting (or worse) when tracing a canceled thread.
99 - the Event module silently broke it's public hook API, causing
100 failures on perls compiled with -Duselongdouble. Requiring
101 the latest version of Event because I don't know which release
102 changed this (it's not mentioned in the ChangeLog).
103 - allow xs level enterleave hooks via CoroAPI.
104
1056.43 Thu Jun 4 15:38:14 CEST 2015
106 - use stability canary.
107 - port to stableperl-5.22.0-1.001.
108 - update libecb.
109
1106.42 Wed Feb 11 20:29:52 CET 2015
111 - Coro::SemaphoreSet->try did not actually work (analyzed by
112 SATO Kentaro).
113 - upgrade libecb to be C11 compliant.
114
1156.41 Sat Sep 6 22:08:46 CEST 2014
116 - restore portability to perl 5.8.x.
117 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
118 up some memory, but fixes "use feature" and similar modules
119 when used inside a Coro.
120 - allow zero as argument to Coro::Channel to mean the same thing
121 as no argument. this works with older versions as well,
122 but wasn't legal until now.
123 - slightly better c header file detection.
124
1256.39 Mon Jun 2 00:00:08 CEST 2014
126 - work around more incompatible changes in 5.20.
127
1286.38 Sun Jun 1 21:54:23 CEST 2014

10 interpreter variables. 130 interpreter variables.

12 by Andreas König). 132 by Andreas König).
