14 - throwing an exception to a thread waiting in
15 Coro::Handle using Coro::EV did not stop the watchers,
16 causing the next call to fail (testcase by Martin Pritchard).
17 - bump minimum perl version to 5.10.
34 18
35TODO: warnhook reports from wrong line number now, when arg is Math::GMP number. 196.48 Sun Oct 4 19:03:51 CEST 2015
20 - fix memory leak when Coro::Handle uses Coro::EV internally
21 (testcase by Sten Sten).
22 - update code to libev 4 API (internally, Coro still used the
23 version 3 API calls).
24 - remove unused hv_sig.
25
266.47 Sat Jul 11 03:58:20 CEST 2015
27 - swap_svs - NVs can be in the SV head beginning with 5.20.
28
296.46 Tue Jun 30 14:36:30 CEST 2015
30 - restore portability to perls with windows fork emulation
31 (patch by Petr Písař).
32
336.45 Tue Jun 30 01:40:08 CEST 2015
34 - restore portability to perl 5.16 and below.
35
366.44 Tue Jun 30 00:41:54 CEST 2015
37 - avoid segfaulting (or worse) when tracing a canceled thread.
38 - the Event module silently broke it's public hook API, causing
39 failures on perls compiled with -Duselongdouble. Requiring
40 the latest version of Event because I don't know which release
41 changed this (it's not mentioned in the ChangeLog).
42 - allow xs level enterleave hooks via CoroAPI.
43
446.43 Thu Jun 4 15:38:14 CEST 2015
45 - use stability canary.
46 - port to stableperl-5.22.0-1.001.
47 - update libecb.
48
496.42 Wed Feb 11 20:29:52 CET 2015
50 - Coro::SemaphoreSet->try did not actually work (analyzed by
51 SATO Kentaro).
52 - upgrade libecb to be C11 compliant.
53
546.41 Sat Sep 6 22:08:46 CEST 2014
55 - restore portability to perl 5.8.x.
56 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
57 up some memory, but fixes "use feature" and similar modules
58 when used inside a Coro.
59 - allow zero as argument to Coro::Channel to mean the same thing
60 as no argument. this works with older versions as well,
61 but wasn't legal until now.
62 - slightly better c header file detection.
63
646.39 Mon Jun 2 00:00:08 CEST 2014
65 - work around more incompatible changes in 5.20.
66
676.38 Sun Jun 1 21:54:23 CEST 2014
68 - check that perl slots actually have enough space to hold
69 interpreter variables.
70 - untested port to perl 5.19 (64 bit tmps indices) (reported
71 by Andreas König).
72 - croak when cancel is called without a thread context.
73
746.37 Tue Mar 4 13:27:33 CET 2014
75 - *sigh*, removed leftover debugging code from debugging a
76 perl bug, of all things.
77
786.36 Tue Mar 4 07:11:59 CET 2014
79 - semaphores would not clear the destroy hook when interrupted
80 by ->throw, causing segfaults or worse.
81 - ->throw on a thread waiting for a semaphore did not acquire
82 the semaphore, but also didn't wake up other waiters,
83 possibly causing a deadlock.
36 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess 84 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
