12 - check that perl slots actually have enough space to hold
13 interpreter variables.
14 - untested port to perl 5.19 (64 bit tmps indices) (reported
15 by Andreas König).
16 - croak when cancel is called without a thread context.
17
186.37 Tue Mar 4 13:27:33 CET 2014
19 - *sigh*, removed leftover debugging code from debugging a
20 perl bug, of all things.
21
226.36 Tue Mar 4 07:11:59 CET 2014
23 - semaphores would not clear the destroy hook when interrupted
24 by ->throw, causing segfaults or worse.
25 - ->throw on a thread waiting for a semaphore did not acquire
26 the semaphore, but also didn't wake up other waiters,
27 possibly causing a deadlock.
28 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
29 to report a full stacktrace, which should help find out
30 where the actual call is.
31 - "atomically" destroy data in slf_destroy, because it is
32 the right thing to do, just in case.
33 - disable ecb.h libm dependency, to compile on ancient systems
34 or under adverse conditions.
35
366.33 Mon Nov 18 11:26:27 CET 2013
37 - do not crash when freeing padlists with holes (in 5.18).
38 - tentative SVt_BIND 5.19 port/fix.
39
406.32 Tue Nov 5 15:35:35 CET 2013
41 - use a new algorithm to derive padlists for perl 5.18. The old
42 one could lead to 0-pointer accesses inside perl (reported
43 by Darin McBride).
44
456.31 Thu May 9 07:39:48 CEST 2013
46 - Coro::AIO requests would crash if the thread was ready'd
47 while the request was ongoing.
48
496.29 Wed May 8 02:55:18 CEST 2013
50 - when an on_destroy handler destructs the coro currently being
51 destructed a perl scalar could be accessed after being freed,
52 likely causing a crash.
53
546.28 Wed Mar 6 06:58:02 CET 2013
55 - clean remnants of existing __DIE__ and __WARN__ handlers so
56 they lose their magic and will not cause segfaults later
57 (testcase by Andrey Sagulin).
58 - improved Coro::State documentation a bit.
59 - Coro::Debug::command now flushes the output.
60 - add hack detection code for x32 abi, because the braindead slugs
61 who designed that made it look exactly like x86_64 without
62 providing proper compile time symbols to test for it. as a result,
63 this detection cannot work reliably.
64 - valgrind stack registering was broken.
65 - do not rely on Time::HiRes anymore in Coro::Debug.
66
676.23 Fri Dec 7 23:36:37 CET 2012
68 - use experimental fiber implementation on native windows
69 perls.
70 - use sizeof (void *) as multiplication factor for stack sizes,
71 to accomodate the totally braindamaged microsoft 64 bit "os".
72 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
73 activeperl 5.16 crashes when PerlIO_define_layer is called due
74 to some bug in the perl dll, strawberry perl at least passes
75 the testsuite.
76 - implement Coro::Handle->peeraddr/host/port, for slightly
77 improved compatibility with LWP.
78 - implement 5.17 compatibility by almost blindly applying a
79 good-looking patch by Father Chrysostomos.
80 - move stack management functions into libcoro 3.
81 - libcoro version 3 "released".
82 - support magic values as timed_io_once args.
83 - recommend AnyEvent 7+ or EV 4+, also require EV
84 version 4 or newer for Coro::EV.
85
866.10 Tue Oct 9 01:14:27 CEST 2012
87 - updated ecb.h, it had a typo that caused it to not compile on many
88 big endian systems (reported by many people).
89 - disable memory fences in ecb.h to improve portability.
90
916.09 Sat Oct 6 23:25:02 CEST 2012
92 - Coro::EV I/O watchers were not interruptible by exceptions
93 (Coro::State::throw) (testcase by sten).
94 - ->throw now puts threads into the ready queue, as this seems to
95 be expected by existing code, and code that doesn't cope with spurious
96 wakeups needs fixing anyway.
97 - use fd -1 in mmap.
98 - cast I32 to int in error message printf.
99 - warn about broken so-called "hardened" kernels.
100
1016.08 Fri Apr 13 12:05:47 CEST 2012
102 - be more aggressive about exiting like perl does - formerly,
103 exiting from the non-main thread would not execute END blocks.
104
1056.07 Fri Nov 11 21:21:48 CET 2011
7 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV). 106 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
