11 - restore portability to perl 5.16 and below.
9 12
136.44 Tue Jun 30 00:41:54 CEST 2015
14 - avoid segfaulting (or worse) when tracing a canceled thread.
15 - the Event module silently broke it's public hook API, causing
16 failures on perls compiled with -Duselongdouble. Requiring
17 the latest version of Event because I don't know which release
18 changed this (it's not mentioned in the ChangeLog).
19 - allow xs level enterleave hooks via CoroAPI.
20
216.43 Thu Jun 4 15:38:14 CEST 2015
22 - use stability canary.
23 - port to stableperl-5.22.0-1.001.
24 - update libecb.
25
266.42 Wed Feb 11 20:29:52 CET 2015
27 - Coro::SemaphoreSet->try did not actually work (analyzed by
28 SATO Kentaro).
29 - upgrade libecb to be C11 compliant.
30
316.41 Sat Sep 6 22:08:46 CEST 2014
32 - restore portability to perl 5.8.x.
33 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
34 up some memory, but fixes "use feature" and similar modules
35 when used inside a Coro.
36 - allow zero as argument to Coro::Channel to mean the same thing
37 as no argument. this works with older versions as well,
38 but wasn't legal until now.
39 - slightly better c header file detection.
40
416.39 Mon Jun 2 00:00:08 CEST 2014
42 - work around more incompatible changes in 5.20.
43
446.38 Sun Jun 1 21:54:23 CEST 2014
45 - check that perl slots actually have enough space to hold
46 interpreter variables.
47 - untested port to perl 5.19 (64 bit tmps indices) (reported
48 by Andreas König).
49 - croak when cancel is called without a thread context.
50
516.37 Tue Mar 4 13:27:33 CET 2014
52 - *sigh*, removed leftover debugging code from debugging a
53 perl bug, of all things.
54
556.36 Tue Mar 4 07:11:59 CET 2014
56 - semaphores would not clear the destroy hook when interrupted
57 by ->throw, causing segfaults or worse.
58 - ->throw on a thread waiting for a semaphore did not acquire
59 the semaphore, but also didn't wake up other waiters,
60 possibly causing a deadlock.
61 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
62 to report a full stacktrace, which should help find out
63 where the actual call is.
64 - "atomically" destroy data in slf_destroy, because it is
65 the right thing to do, just in case.
66 - disable ecb.h libm dependency, to compile on ancient systems
67 or under adverse conditions.
68
696.33 Mon Nov 18 11:26:27 CET 2013
70 - do not crash when freeing padlists with holes (in 5.18).
71 - tentative SVt_BIND 5.19 port/fix.
72
736.32 Tue Nov 5 15:35:35 CET 2013
74 - use a new algorithm to derive padlists for perl 5.18. The old
75 one could lead to 0-pointer accesses inside perl (reported
76 by Darin McBride).
77
786.31 Thu May 9 07:39:48 CEST 2013
79 - Coro::AIO requests would crash if the thread was ready'd
80 while the request was ongoing.
81
826.29 Wed May 8 02:55:18 CEST 2013
83 - when an on_destroy handler destructs the coro currently being
84 destructed a perl scalar could be accessed after being freed,
85 likely causing a crash.
86
876.28 Wed Mar 6 06:58:02 CET 2013
88 - clean remnants of existing __DIE__ and __WARN__ handlers so
89 they lose their magic and will not cause segfaults later
90 (testcase by Andrey Sagulin).
91 - improved Coro::State documentation a bit.
92 - Coro::Debug::command now flushes the output.
93 - add hack detection code for x32 abi, because the braindead slugs
94 who designed that made it look exactly like x86_64 without
95 providing proper compile time symbols to test for it. as a result,
96 this detection cannot work reliably.
97 - valgrind stack registering was broken.
98 - do not rely on Time::HiRes anymore in Coro::Debug.
