106.44 Tue Jun 30 00:41:54 CEST 2015
11 - avoid segfaulting (or worse) when tracing a canceled thread.
12 - the Event module silently broke it's public hook API, causing
13 failures on perls compiled with -Duselongdouble. Requiring
14 the latest version of Event because I don't know which release
15 changed this (it's not mentioned in the ChangeLog).
16 - allow xs level enterleave hooks via CoroAPI.
17
186.43 Thu Jun 4 15:38:14 CEST 2015
19 - use stability canary.
20 - port to stableperl-5.22.0-1.001.
21 - update libecb.
22
236.42 Wed Feb 11 20:29:52 CET 2015
24 - Coro::SemaphoreSet->try did not actually work (analyzed by
25 SATO Kentaro).
26 - upgrade libecb to be C11 compliant.
27
286.41 Sat Sep 6 22:08:46 CEST 2014
29 - restore portability to perl 5.8.x.
30 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
31 up some memory, but fixes "use feature" and similar modules
32 when used inside a Coro.
33 - allow zero as argument to Coro::Channel to mean the same thing
34 as no argument. this works with older versions as well,
35 but wasn't legal until now.
36 - slightly better c header file detection.
37
386.39 Mon Jun 2 00:00:08 CEST 2014
39 - work around more incompatible changes in 5.20.
40
416.38 Sun Jun 1 21:54:23 CEST 2014
42 - check that perl slots actually have enough space to hold
43 interpreter variables.
44 - untested port to perl 5.19 (64 bit tmps indices) (reported
45 by Andreas König).
46 - croak when cancel is called without a thread context.
47
486.37 Tue Mar 4 13:27:33 CET 2014
49 - *sigh*, removed leftover debugging code from debugging a
50 perl bug, of all things.
51
526.36 Tue Mar 4 07:11:59 CET 2014
53 - semaphores would not clear the destroy hook when interrupted
54 by ->throw, causing segfaults or worse.
55 - ->throw on a thread waiting for a semaphore did not acquire
56 the semaphore, but also didn't wake up other waiters,
57 possibly causing a deadlock.
58 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
59 to report a full stacktrace, which should help find out
60 where the actual call is.
61 - "atomically" destroy data in slf_destroy, because it is
62 the right thing to do, just in case.
63 - disable ecb.h libm dependency, to compile on ancient systems
64 or under adverse conditions.
65
666.33 Mon Nov 18 11:26:27 CET 2013
67 - do not crash when freeing padlists with holes (in 5.18).
68 - tentative SVt_BIND 5.19 port/fix.
69
706.32 Tue Nov 5 15:35:35 CET 2013
71 - use a new algorithm to derive padlists for perl 5.18. The old
72 one could lead to 0-pointer accesses inside perl (reported
73 by Darin McBride).
74
756.31 Thu May 9 07:39:48 CEST 2013
76 - Coro::AIO requests would crash if the thread was ready'd
77 while the request was ongoing.
78
796.29 Wed May 8 02:55:18 CEST 2013
80 - when an on_destroy handler destructs the coro currently being
81 destructed a perl scalar could be accessed after being freed,
82 likely causing a crash.
83
846.28 Wed Mar 6 06:58:02 CET 2013
85 - clean remnants of existing __DIE__ and __WARN__ handlers so
86 they lose their magic and will not cause segfaults later
87 (testcase by Andrey Sagulin).
7 - improved Coro::State documentation a bit. 88 - improved Coro::State documentation a bit.
