9 - re-try JIT allocation without PROT_EXEC, to hopefully improve
10 portability.
11
126.511 Sun Jun 26 23:44:50 CEST 2016
13 - make it compile with threaded perls again.
14 - simplify and speed up __DIE__ and __WARN__ handling.
15
166.51 Sat Jun 25 20:57:20 CEST 2016
17 - 6.5 release didn't compile on most older perls due to
18 a logic error enabling experimental 5.24 code for all versions.
19 - since various broken or deficient patches float around
20 to work around the vtbl API breakage in perl, let's provide
21 our own workaround, which seems to be much less invasive
22 and more compatible than the approaches seen so far. YMMV.
23 - work around assertion failure in perl_destruct on 5.24
24 (analyzed by Dave Mitchell).
25
266.5 Wed Jun 22 22:23:50 CEST 2016
27 - swap_sv swapping order was not symmetrical, causing
28 wrong swaps when swap_sv was used multiple times on the
29 same sv in the same thread.
30 - swap_sv calls can now be undone by calling it again
31 with the same variables.
32 - swap_sv calls will now be undone in async_pool threads.
33 - split Coro::Semaphore::up/adjust into separate xs functions
34 for better error reporting, at slight codesize increase.
35 - (libcoro) arm assembly support, please test and report.
36 - adjust to PL_savestack changes in perl 5.24 (adapted from
37 the debian patch, which unfortunately gets it wrong).
38
396.49 Sat Oct 17 01:40:12 CEST 2015
40 - throwing an exception to a thread waiting in
41 Coro::Handle using Coro::EV did not stop the watchers,
42 causing the next call to fail (testcase by Martin Pritchard).
43 - bump minimum perl version to 5.10.
44
456.48 Sun Oct 4 19:03:51 CEST 2015
46 - fix memory leak when Coro::Handle uses Coro::EV internally
47 (testcase by Sten Sten).
48 - update code to libev 4 API (internally, Coro still used the
49 version 3 API calls).
50 - remove unused hv_sig.
51
526.47 Sat Jul 11 03:58:20 CEST 2015
53 - swap_svs - NVs can be in the SV head beginning with 5.20.
54
556.46 Tue Jun 30 14:36:30 CEST 2015
56 - restore portability to perls with windows fork emulation
57 (patch by Petr Písař).
58
596.45 Tue Jun 30 01:40:08 CEST 2015
60 - restore portability to perl 5.16 and below.
61
626.44 Tue Jun 30 00:41:54 CEST 2015
63 - avoid segfaulting (or worse) when tracing a canceled thread.
64 - the Event module silently broke it's public hook API, causing
65 failures on perls compiled with -Duselongdouble. Requiring
66 the latest version of Event because I don't know which release
67 changed this (it's not mentioned in the ChangeLog).
68 - allow xs level enterleave hooks via CoroAPI.
69
706.43 Thu Jun 4 15:38:14 CEST 2015
71 - use stability canary.
72 - port to stableperl-5.22.0-1.001.
73 - update libecb.
74
756.42 Wed Feb 11 20:29:52 CET 2015
76 - Coro::SemaphoreSet->try did not actually work (analyzed by
77 SATO Kentaro).
78 - upgrade libecb to be C11 compliant.
79
806.41 Sat Sep 6 22:08:46 CEST 2014
81 - restore portability to perl 5.8.x.
82 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
83 up some memory, but fixes "use feature" and similar modules
84 when used inside a Coro.
85 - allow zero as argument to Coro::Channel to mean the same thing
86 as no argument. this works with older versions as well,
87 but wasn't legal until now.
88 - slightly better c header file detection.
89
906.39 Mon Jun 2 00:00:08 CEST 2014
91 - work around more incompatible changes in 5.20.
92
936.38 Sun Jun 1 21:54:23 CEST 2014
94 - check that perl slots actually have enough space to hold
95 interpreter variables.
96 - untested port to perl 5.19 (64 bit tmps indices) (reported
97 by Andreas König).
98 - croak when cancel is called without a thread context.
99
1006.37 Tue Mar 4 13:27:33 CET 2014
101 - *sigh*, removed leftover debugging code from debugging a
102 perl bug, of all things.
103
1046.36 Tue Mar 4 07:11:59 CET 2014
105 - semaphores would not clear the destroy hook when interrupted
106 by ->throw, causing segfaults or worse.
107 - ->throw on a thread waiting for a semaphore did not acquire
108 the semaphore, but also didn't wake up other waiters,
109 possibly causing a deadlock.
110 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
111 to report a full stacktrace, which should help find out
112 where the actual call is.
113 - "atomically" destroy data in slf_destroy, because it is
114 the right thing to do, just in case.
115 - disable ecb.h libm dependency, to compile on ancient systems
116 or under adverse conditions.
117
1186.33 Mon Nov 18 11:26:27 CET 2013
119 - do not crash when freeing padlists with holes (in 5.18).
9 - tentative SVt_BIND 5.19 port/fix. 120 - tentative SVt_BIND 5.19 port/fix.
