9 - untested port to perl 5.19 (64 bit tmps indices) (reported
10 by Andreas König).
11 - croak when cancel is called without a thread context.
12
136.37 Tue Mar 4 13:27:33 CET 2014
14 - *sigh*, removed leftover debugging code from debugging a
15 perl bug, of all things.
16
176.36 Tue Mar 4 07:11:59 CET 2014
18 - semaphores would not clear the destroy hook when interrupted
19 by ->throw, causing segfaults or worse.
20 - ->throw on a thread waiting for a semaphore did not acquire
21 the semaphore, but also didn't wake up other waiters,
22 possibly causing a deadlock.
23 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
24 to report a full stacktrace, which should help find out
25 where the actual call is.
26 - "atomically" destroy data in slf_destroy, because it is
27 the right thing to do, just in case.
28 - disable ecb.h libm dependency, to compile on ancient systems
29 or under adverse conditions.
30
316.33 Mon Nov 18 11:26:27 CET 2013
32 - do not crash when freeing padlists with holes (in 5.18).
33 - tentative SVt_BIND 5.19 port/fix.
34
356.32 Tue Nov 5 15:35:35 CET 2013
36 - use a new algorithm to derive padlists for perl 5.18. The old
37 one could lead to 0-pointer accesses inside perl (reported
38 by Darin McBride).
39
406.31 Thu May 9 07:39:48 CEST 2013
41 - Coro::AIO requests would crash if the thread was ready'd
42 while the request was ongoing.
43
446.29 Wed May 8 02:55:18 CEST 2013
45 - when an on_destroy handler destructs the coro currently being
46 destructed a perl scalar could be accessed after being freed,
47 likely causing a crash.
48
496.28 Wed Mar 6 06:58:02 CET 2013
50 - clean remnants of existing __DIE__ and __WARN__ handlers so
51 they lose their magic and will not cause segfaults later
52 (testcase by Andrey Sagulin).
53 - improved Coro::State documentation a bit.
54 - Coro::Debug::command now flushes the output.
55 - add hack detection code for x32 abi, because the braindead slugs
56 who designed that made it look exactly like x86_64 without
57 providing proper compile time symbols to test for it. as a result,
58 this detection cannot work reliably.
59 - valgrind stack registering was broken.
60 - do not rely on Time::HiRes anymore in Coro::Debug.
61
626.23 Fri Dec 7 23:36:37 CET 2012
63 - use experimental fiber implementation on native windows
64 perls.
65 - use sizeof (void *) as multiplication factor for stack sizes,
66 to accomodate the totally braindamaged microsoft 64 bit "os".
67 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
68 activeperl 5.16 crashes when PerlIO_define_layer is called due
69 to some bug in the perl dll, strawberry perl at least passes
70 the testsuite.
71 - implement Coro::Handle->peeraddr/host/port, for slightly
72 improved compatibility with LWP.
73 - implement 5.17 compatibility by almost blindly applying a
74 good-looking patch by Father Chrysostomos.
75 - move stack management functions into libcoro 3.
76 - libcoro version 3 "released".
77 - support magic values as timed_io_once args.
78 - recommend AnyEvent 7+ or EV 4+, also require EV
79 version 4 or newer for Coro::EV.
