10 - safe_cancel no longer croaks when called on already-destroyed
11 thread, but instead "just works".
12
136.513 Sat Jul 15 01:18:51 CEST 2017
14 - experimental 5.22 comaptibility changes (PadlistNAMES).
15 - removed attributes example and made sure the other examples
16 still work.
17 - fix some statevar types for newer perls, should be of no consequence.
18
196.512 Fri Jul 14 05:03:17 CEST 2017
20 - seems to pass test suite down till 5.8.9, so make this the
21 minimum requirement in Makefile.PL.
22 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
23 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
24 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
25 fortified longjmp variants in some libcs.
26 - re-try JIT allocation without PROT_EXEC, to hopefully improve
27 portability (still doesn't seem to work around broken selinux
28 mmap everywhere).
29 - speling fixes (Xavier Guimard).
30
316.511 Sun Jun 26 23:44:50 CEST 2016
32 - make it compile with threaded perls again.
33 - simplify and speed up __DIE__ and __WARN__ handling.
34
356.51 Sat Jun 25 20:57:20 CEST 2016
36 - 6.5 release didn't compile on most older perls due to
37 a logic error enabling experimental 5.24 code for all versions.
38 - since various broken or deficient patches float around
39 to work around the vtbl API breakage in perl, let's provide
40 our own workaround, which seems to be much less invasive
41 and more compatible than the approaches seen so far. YMMV.
42 - work around assertion failure in perl_destruct on 5.24
43 (analyzed by Dave Mitchell).
44
456.5 Wed Jun 22 22:23:50 CEST 2016
46 - swap_sv swapping order was not symmetrical, causing
47 wrong swaps when swap_sv was used multiple times on the
48 same sv in the same thread.
49 - swap_sv calls can now be undone by calling it again
50 with the same variables.
51 - swap_sv calls will now be undone in async_pool threads.
52 - split Coro::Semaphore::up/adjust into separate xs functions
53 for better error reporting, at slight codesize increase.
54 - (libcoro) arm assembly support, please test and report.
55 - adjust to PL_savestack changes in perl 5.24 (adapted from
56 the debian patch, which unfortunately gets it wrong).
57
586.49 Sat Oct 17 01:40:12 CEST 2015
59 - throwing an exception to a thread waiting in
60 Coro::Handle using Coro::EV did not stop the watchers,
61 causing the next call to fail (testcase by Martin Pritchard).
62 - bump minimum perl version to 5.10.
63
646.48 Sun Oct 4 19:03:51 CEST 2015
65 - fix memory leak when Coro::Handle uses Coro::EV internally
66 (testcase by Sten Sten).
67 - update code to libev 4 API (internally, Coro still used the
68 version 3 API calls).
69 - remove unused hv_sig.
70
716.47 Sat Jul 11 03:58:20 CEST 2015
72 - swap_svs - NVs can be in the SV head beginning with 5.20.
73
746.46 Tue Jun 30 14:36:30 CEST 2015
75 - restore portability to perls with windows fork emulation
76 (patch by Petr Písař).
77
786.45 Tue Jun 30 01:40:08 CEST 2015
79 - restore portability to perl 5.16 and below.
80
816.44 Tue Jun 30 00:41:54 CEST 2015
82 - avoid segfaulting (or worse) when tracing a canceled thread.
83 - the Event module silently broke it's public hook API, causing
84 failures on perls compiled with -Duselongdouble. Requiring
85 the latest version of Event because I don't know which release
86 changed this (it's not mentioned in the ChangeLog).
87 - allow xs level enterleave hooks via CoroAPI.
88
896.43 Thu Jun 4 15:38:14 CEST 2015
90 - use stability canary.
91 - port to stableperl-5.22.0-1.001.
92 - update libecb.
93
946.42 Wed Feb 11 20:29:52 CET 2015
95 - Coro::SemaphoreSet->try did not actually work (analyzed by
96 SATO Kentaro).
97 - upgrade libecb to be C11 compliant.
98
996.41 Sat Sep 6 22:08:46 CEST 2014
100 - restore portability to perl 5.8.x.
101 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
102 up some memory, but fixes "use feature" and similar modules
103 when used inside a Coro.
104 - allow zero as argument to Coro::Channel to mean the same thing
105 as no argument. this works with older versions as well,
106 but wasn't legal until now.
107 - slightly better c header file detection.
108
1096.39 Mon Jun 2 00:00:08 CEST 2014
110 - work around more incompatible changes in 5.20.
111
1126.38 Sun Jun 1 21:54:23 CEST 2014
113 - check that perl slots actually have enough space to hold
114 interpreter variables.
115 - untested port to perl 5.19 (64 bit tmps indices) (reported
116 by Andreas König).
117 - croak when cancel is called without a thread context.
118
1196.37 Tue Mar 4 13:27:33 CET 2014
120 - *sigh*, removed leftover debugging code from debugging a
121 perl bug, of all things.
122
1236.36 Tue Mar 4 07:11:59 CET 2014
124 - semaphores would not clear the destroy hook when interrupted
125 by ->throw, causing segfaults or worse.
126 - ->throw on a thread waiting for a semaphore did not acquire
127 the semaphore, but also didn't wake up other waiters,
128 possibly causing a deadlock.
129 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
130 to report a full stacktrace, which should help find out
131 where the actual call is.
132 - "atomically" destroy data in slf_destroy, because it is
133 the right thing to do, just in case.
134 - disable ecb.h libm dependency, to compile on ancient systems
135 or under adverse conditions.
136
1376.33 Mon Nov 18 11:26:27 CET 2013
138 - do not crash when freeing padlists with holes (in 5.18).
139 - tentative SVt_BIND 5.19 port/fix.

10 - use a new algorithm to derive padlists for perl 5.18. The old 142 - use a new algorithm to derive padlists for perl 5.18. The old
11 one could lead to 0-pointer accesses inside perl (reported 143 one could lead to 0-pointer accesses inside perl (reported
12 by Darin McBride). 144 by Darin McBride).

122 reach about half the speed of non-threaded perls). 254 reach about half the speed of non-threaded perls).
123 - slightly modernise Coro::Intro, add section about rouse functions. 255 - slightly modernise Coro::Intro, add section about rouse functions.
