10 - do not crash when freeing padlists with holes (in 5.18).
11 - tentative SVt_BIND 5.19 port/fix.
12
136.32 Tue Nov 5 15:35:35 CET 2013
14 - use a new algorithm to derive padlists for perl 5.18. The old
15 one could lead to 0-pointer accesses inside perl (reported
16 by Darin McBride).
17
186.31 Thu May 9 07:39:48 CEST 2013
19 - Coro::AIO requests would crash if the thread was ready'd
20 while the request was ongoing.
21
226.29 Wed May 8 02:55:18 CEST 2013
23 - when an on_destroy handler destructs the coro currently being
24 destructed a perl scalar could be accessed after being freed,
25 likely causing a crash.
26
276.28 Wed Mar 6 06:58:02 CET 2013
28 - clean remnants of existing __DIE__ and __WARN__ handlers so
29 they lose their magic and will not cause segfaults later
30 (testcase by Andrey Sagulin).
31 - improved Coro::State documentation a bit.
32 - Coro::Debug::command now flushes the output.
33 - add hack detection code for x32 abi, because the braindead slugs
34 who designed that made it look exactly like x86_64 without
35 providing proper compile time symbols to test for it. as a result,
36 this detection cannot work reliably.
37 - valgrind stack registering was broken.
38 - do not rely on Time::HiRes anymore in Coro::Debug.
39
406.23 Fri Dec 7 23:36:37 CET 2012
41 - use experimental fiber implementation on native windows
42 perls.
43 - use sizeof (void *) as multiplication factor for stack sizes,
44 to accomodate the totally braindamaged microsoft 64 bit "os".
45 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
46 activeperl 5.16 crashes when PerlIO_define_layer is called due
47 to some bug in the perl dll, strawberry perl at least passes
48 the testsuite.
49 - implement Coro::Handle->peeraddr/host/port, for slightly
50 improved compatibility with LWP.
51 - implement 5.17 compatibility by almost blindly applying a
52 good-looking patch by Father Chrysostomos.
53 - move stack management functions into libcoro 3.
54 - libcoro version 3 "released".
55 - support magic values as timed_io_once args.
56 - recommend AnyEvent 7+ or EV 4+, also require EV
57 version 4 or newer for Coro::EV.
58
596.10 Tue Oct 9 01:14:27 CEST 2012
60 - updated ecb.h, it had a typo that caused it to not compile on many
61 big endian systems (reported by many people).
62 - disable memory fences in ecb.h to improve portability.
63
646.09 Sat Oct 6 23:25:02 CEST 2012
65 - Coro::EV I/O watchers were not interruptible by exceptions
66 (Coro::State::throw) (testcase by sten).
67 - ->throw now puts threads into the ready queue, as this seems to
68 be expected by existing code, and code that doesn't cope with spurious
69 wakeups needs fixing anyway.
70 - use fd -1 in mmap.
71 - cast I32 to int in error message printf.
72 - warn about broken so-called "hardened" kernels.
73
746.08 Fri Apr 13 12:05:47 CEST 2012
75 - be more aggressive about exiting like perl does - formerly,
76 exiting from the non-main thread would not execute END blocks.
77
786.07 Fri Nov 11 21:21:48 CET 2011
7 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV). 79 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
8 - update ecb.h. 80 - update ecb.h.
