13 - safe_cancel no longer croaks when called on already-destroyed
14 thread, but instead "just works".
34 15
35TODO: warnhook reports from wrong line number now, when arg is Math::GMP number. 166.513 Sat Jul 15 01:18:51 CEST 2017
17 - experimental 5.22 comaptibility changes (PadlistNAMES).
18 - removed attributes example and made sure the other examples
19 still work.
20 - fix some statevar types for newer perls, should be of no consequence.
21
226.512 Fri Jul 14 05:03:17 CEST 2017
23 - seems to pass test suite down till 5.8.9, so make this the
24 minimum requirement in Makefile.PL.
25 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
26 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
27 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
28 fortified longjmp variants in some libcs.
29 - re-try JIT allocation without PROT_EXEC, to hopefully improve
30 portability (still doesn't seem to work around broken selinux
31 mmap everywhere).
32 - speling fixes (Xavier Guimard).
33
346.511 Sun Jun 26 23:44:50 CEST 2016
35 - make it compile with threaded perls again.
36 - simplify and speed up __DIE__ and __WARN__ handling.
37
386.51 Sat Jun 25 20:57:20 CEST 2016
39 - 6.5 release didn't compile on most older perls due to
40 a logic error enabling experimental 5.24 code for all versions.
41 - since various broken or deficient patches float around
42 to work around the vtbl API breakage in perl, let's provide
43 our own workaround, which seems to be much less invasive
44 and more compatible than the approaches seen so far. YMMV.
45 - work around assertion failure in perl_destruct on 5.24
46 (analyzed by Dave Mitchell).
47
486.5 Wed Jun 22 22:23:50 CEST 2016
49 - swap_sv swapping order was not symmetrical, causing
50 wrong swaps when swap_sv was used multiple times on the
51 same sv in the same thread.
52 - swap_sv calls can now be undone by calling it again
53 with the same variables.
54 - swap_sv calls will now be undone in async_pool threads.
55 - split Coro::Semaphore::up/adjust into separate xs functions
56 for better error reporting, at slight codesize increase.
57 - (libcoro) arm assembly support, please test and report.
58 - adjust to PL_savestack changes in perl 5.24 (adapted from
59 the debian patch, which unfortunately gets it wrong).
60
616.49 Sat Oct 17 01:40:12 CEST 2015
62 - throwing an exception to a thread waiting in
63 Coro::Handle using Coro::EV did not stop the watchers,
64 causing the next call to fail (testcase by Martin Pritchard).
65 - bump minimum perl version to 5.10.
66
676.48 Sun Oct 4 19:03:51 CEST 2015
68 - fix memory leak when Coro::Handle uses Coro::EV internally
69 (testcase by Sten Sten).
70 - update code to libev 4 API (internally, Coro still used the
71 version 3 API calls).
72 - remove unused hv_sig.
73
746.47 Sat Jul 11 03:58:20 CEST 2015
75 - swap_svs - NVs can be in the SV head beginning with 5.20.
76
776.46 Tue Jun 30 14:36:30 CEST 2015
78 - restore portability to perls with windows fork emulation
79 (patch by Petr Písař).
80
816.45 Tue Jun 30 01:40:08 CEST 2015
82 - restore portability to perl 5.16 and below.
83
846.44 Tue Jun 30 00:41:54 CEST 2015
85 - avoid segfaulting (or worse) when tracing a canceled thread.
86 - the Event module silently broke it's public hook API, causing
87 failures on perls compiled with -Duselongdouble. Requiring
88 the latest version of Event because I don't know which release
89 changed this (it's not mentioned in the ChangeLog).
90 - allow xs level enterleave hooks via CoroAPI.
91
926.43 Thu Jun 4 15:38:14 CEST 2015
93 - use stability canary.
94 - port to stableperl-5.22.0-1.001.
95 - update libecb.
96
976.42 Wed Feb 11 20:29:52 CET 2015
98 - Coro::SemaphoreSet->try did not actually work (analyzed by
99 SATO Kentaro).
100 - upgrade libecb to be C11 compliant.
101
1026.41 Sat Sep 6 22:08:46 CEST 2014
103 - restore portability to perl 5.8.x.
104 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
105 up some memory, but fixes "use feature" and similar modules
106 when used inside a Coro.
107 - allow zero as argument to Coro::Channel to mean the same thing
108 as no argument. this works with older versions as well,
109 but wasn't legal until now.
110 - slightly better c header file detection.
111
1126.39 Mon Jun 2 00:00:08 CEST 2014
113 - work around more incompatible changes in 5.20.
114
1156.38 Sun Jun 1 21:54:23 CEST 2014
116 - check that perl slots actually have enough space to hold
117 interpreter variables.
118 - untested port to perl 5.19 (64 bit tmps indices) (reported
119 by Andreas König).
120 - croak when cancel is called without a thread context.
121
1226.37 Tue Mar 4 13:27:33 CET 2014
123 - *sigh*, removed leftover debugging code from debugging a
124 perl bug, of all things.
125
1266.36 Tue Mar 4 07:11:59 CET 2014
127 - semaphores would not clear the destroy hook when interrupted
128 by ->throw, causing segfaults or worse.
129 - ->throw on a thread waiting for a semaphore did not acquire
130 the semaphore, but also didn't wake up other waiters,
131 possibly causing a deadlock.
36 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess 132 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
37 to report a full stacktrace, which should help find out 133 to report a full stacktrace, which should help find out
38 where the actual call is. 134 where the actual call is.
39 - "atomically" destroy data in slf_destroy, because it is 135 - "atomically" destroy data in slf_destroy, because it is
40 the right thing to do, just in case. 136 the right thing to do, just in case.
