106.43 Thu Jun 4 15:38:14 CEST 2015
11 - use stability canary.
12 - port to stableperl-5.22.0-1.001.
13 - update libecb.
14
156.42 Wed Feb 11 20:29:52 CET 2015
16 - Coro::SemaphoreSet->try did not actually work (analyzed by
17 SATO Kentaro).
18 - upgrade libecb to be C11 compliant.
19
206.41 Sat Sep 6 22:08:46 CEST 2014
21 - restore portability to perl 5.8.x.
22 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
23 up some memory, but fixes "use feature" and similar modules
24 when used inside a Coro.
25 - allow zero as argument to Coro::Channel to mean the same thing
26 as no argument. this works with older versions as well,
27 but wasn't legal until now.
28 - slightly better c header file detection.
29
306.39 Mon Jun 2 00:00:08 CEST 2014
31 - work around more incompatible changes in 5.20.
32
336.38 Sun Jun 1 21:54:23 CEST 2014
34 - check that perl slots actually have enough space to hold
35 interpreter variables.
36 - untested port to perl 5.19 (64 bit tmps indices) (reported
37 by Andreas König).
38 - croak when cancel is called without a thread context.
39
406.37 Tue Mar 4 13:27:33 CET 2014
41 - *sigh*, removed leftover debugging code from debugging a
42 perl bug, of all things.
43
446.36 Tue Mar 4 07:11:59 CET 2014
45 - semaphores would not clear the destroy hook when interrupted
46 by ->throw, causing segfaults or worse.
47 - ->throw on a thread waiting for a semaphore did not acquire
48 the semaphore, but also didn't wake up other waiters,
49 possibly causing a deadlock.
50 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
51 to report a full stacktrace, which should help find out
52 where the actual call is.
53 - "atomically" destroy data in slf_destroy, because it is
54 the right thing to do, just in case.
55 - disable ecb.h libm dependency, to compile on ancient systems
56 or under adverse conditions.
57
586.33 Mon Nov 18 11:26:27 CET 2013
59 - do not crash when freeing padlists with holes (in 5.18).
60 - tentative SVt_BIND 5.19 port/fix.
61
626.32 Tue Nov 5 15:35:35 CET 2013
63 - use a new algorithm to derive padlists for perl 5.18. The old
64 one could lead to 0-pointer accesses inside perl (reported
65 by Darin McBride).
66
676.31 Thu May 9 07:39:48 CEST 2013
68 - Coro::AIO requests would crash if the thread was ready'd
69 while the request was ongoing.
70
716.29 Wed May 8 02:55:18 CEST 2013
72 - when an on_destroy handler destructs the coro currently being
73 destructed a perl scalar could be accessed after being freed,
74 likely causing a crash.
75
766.28 Wed Mar 6 06:58:02 CET 2013
77 - clean remnants of existing __DIE__ and __WARN__ handlers so
78 they lose their magic and will not cause segfaults later
79 (testcase by Andrey Sagulin).
80 - improved Coro::State documentation a bit.
81 - Coro::Debug::command now flushes the output.
82 - add hack detection code for x32 abi, because the braindead slugs
83 who designed that made it look exactly like x86_64 without
84 providing proper compile time symbols to test for it. as a result,
85 this detection cannot work reliably.
86 - valgrind stack registering was broken.
87 - do not rely on Time::HiRes anymore in Coro::Debug.
88
896.23 Fri Dec 7 23:36:37 CET 2012
90 - use experimental fiber implementation on native windows
91 perls.
92 - use sizeof (void *) as multiplication factor for stack sizes,
93 to accomodate the totally braindamaged microsoft 64 bit "os".
94 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
95 activeperl 5.16 crashes when PerlIO_define_layer is called due
96 to some bug in the perl dll, strawberry perl at least passes
97 the testsuite.
98 - implement Coro::Handle->peeraddr/host/port, for slightly
99 improved compatibility with LWP.
100 - implement 5.17 compatibility by almost blindly applying a
101 good-looking patch by Father Chrysostomos.
102 - move stack management functions into libcoro 3.
103 - libcoro version 3 "released".
104 - support magic values as timed_io_once args.
105 - recommend AnyEvent 7+ or EV 4+, also require EV
106 version 4 or newer for Coro::EV.
