6 9
76.29 10 - swap_sv swapping order was not symmetrical, causing
11 wrong swaps when swap_sv was used multiple times on the
12 same sv in the same thread.
13 - swap_sv calls can now be undone by calling it again
14 with the same variables.
15 - split Coro::Semaphore::up/adjust into separate xs functions
16 for better error reporting, at slight codesize increase.
17 - (libcoro) arm assembly support.
18
196.49 Sat Oct 17 01:40:12 CEST 2015
20 - throwing an exception to a thread waiting in
21 Coro::Handle using Coro::EV did not stop the watchers,
22 causing the next call to fail (testcase by Martin Pritchard).
23 - bump minimum perl version to 5.10.
24
256.48 Sun Oct 4 19:03:51 CEST 2015
26 - fix memory leak when Coro::Handle uses Coro::EV internally
27 (testcase by Sten Sten).
28 - update code to libev 4 API (internally, Coro still used the
29 version 3 API calls).
30 - remove unused hv_sig.
31
326.47 Sat Jul 11 03:58:20 CEST 2015
33 - swap_svs - NVs can be in the SV head beginning with 5.20.
34
356.46 Tue Jun 30 14:36:30 CEST 2015
36 - restore portability to perls with windows fork emulation
37 (patch by Petr Písař).
38
396.45 Tue Jun 30 01:40:08 CEST 2015
40 - restore portability to perl 5.16 and below.
41
426.44 Tue Jun 30 00:41:54 CEST 2015
43 - avoid segfaulting (or worse) when tracing a canceled thread.
44 - the Event module silently broke it's public hook API, causing
45 failures on perls compiled with -Duselongdouble. Requiring
46 the latest version of Event because I don't know which release
47 changed this (it's not mentioned in the ChangeLog).
48 - allow xs level enterleave hooks via CoroAPI.
49
506.43 Thu Jun 4 15:38:14 CEST 2015
51 - use stability canary.
52 - port to stableperl-5.22.0-1.001.
53 - update libecb.
54
556.42 Wed Feb 11 20:29:52 CET 2015
56 - Coro::SemaphoreSet->try did not actually work (analyzed by
57 SATO Kentaro).
58 - upgrade libecb to be C11 compliant.
59
606.41 Sat Sep 6 22:08:46 CEST 2014
61 - restore portability to perl 5.8.x.
62 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
63 up some memory, but fixes "use feature" and similar modules
64 when used inside a Coro.
65 - allow zero as argument to Coro::Channel to mean the same thing
66 as no argument. this works with older versions as well,
67 but wasn't legal until now.
68 - slightly better c header file detection.
69
706.39 Mon Jun 2 00:00:08 CEST 2014
71 - work around more incompatible changes in 5.20.
72
736.38 Sun Jun 1 21:54:23 CEST 2014
74 - check that perl slots actually have enough space to hold
75 interpreter variables.
76 - untested port to perl 5.19 (64 bit tmps indices) (reported
77 by Andreas König).
78 - croak when cancel is called without a thread context.
79
806.37 Tue Mar 4 13:27:33 CET 2014
81 - *sigh*, removed leftover debugging code from debugging a
82 perl bug, of all things.
83
846.36 Tue Mar 4 07:11:59 CET 2014
85 - semaphores would not clear the destroy hook when interrupted
86 by ->throw, causing segfaults or worse.
87 - ->throw on a thread waiting for a semaphore did not acquire
88 the semaphore, but also didn't wake up other waiters,
89 possibly causing a deadlock.
90 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
91 to report a full stacktrace, which should help find out
92 where the actual call is.
93 - "atomically" destroy data in slf_destroy, because it is
94 the right thing to do, just in case.
95 - disable ecb.h libm dependency, to compile on ancient systems
96 or under adverse conditions.
97
986.33 Mon Nov 18 11:26:27 CET 2013
99 - do not crash when freeing padlists with holes (in 5.18).
100 - tentative SVt_BIND 5.19 port/fix.
101
1026.32 Tue Nov 5 15:35:35 CET 2013
103 - use a new algorithm to derive padlists for perl 5.18. The old
104 one could lead to 0-pointer accesses inside perl (reported
105 by Darin McBride).
106
1076.31 Thu May 9 07:39:48 CEST 2013
108 - Coro::AIO requests would crash if the thread was ready'd
109 while the request was ongoing.
