11 - work around more incompatible changes in 5.20.
9 12
136.38 Sun Jun 1 21:54:23 CEST 2014
14 - check that perl slots actually have enough space to hold
15 interpreter variables.
16 - untested port to perl 5.19 (64 bit tmps indices) (reported
17 by Andreas König).
18 - croak when cancel is called without a thread context.
19
206.37 Tue Mar 4 13:27:33 CET 2014
21 - *sigh*, removed leftover debugging code from debugging a
22 perl bug, of all things.
23
246.36 Tue Mar 4 07:11:59 CET 2014
25 - semaphores would not clear the destroy hook when interrupted
26 by ->throw, causing segfaults or worse.
27 - ->throw on a thread waiting for a semaphore did not acquire
28 the semaphore, but also didn't wake up other waiters,
29 possibly causing a deadlock.
30 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
31 to report a full stacktrace, which should help find out
32 where the actual call is.
33 - "atomically" destroy data in slf_destroy, because it is
34 the right thing to do, just in case.
35 - disable ecb.h libm dependency, to compile on ancient systems
36 or under adverse conditions.
37
386.33 Mon Nov 18 11:26:27 CET 2013
39 - do not crash when freeing padlists with holes (in 5.18).
40 - tentative SVt_BIND 5.19 port/fix.
41
426.32 Tue Nov 5 15:35:35 CET 2013
43 - use a new algorithm to derive padlists for perl 5.18. The old
44 one could lead to 0-pointer accesses inside perl (reported
45 by Darin McBride).
46
476.31 Thu May 9 07:39:48 CEST 2013
48 - Coro::AIO requests would crash if the thread was ready'd
49 while the request was ongoing.
50
516.29 Wed May 8 02:55:18 CEST 2013
52 - when an on_destroy handler destructs the coro currently being
53 destructed a perl scalar could be accessed after being freed,
54 likely causing a crash.
55
566.28 Wed Mar 6 06:58:02 CET 2013
57 - clean remnants of existing __DIE__ and __WARN__ handlers so
58 they lose their magic and will not cause segfaults later
59 (testcase by Andrey Sagulin).
60 - improved Coro::State documentation a bit.
61 - Coro::Debug::command now flushes the output.
62 - add hack detection code for x32 abi, because the braindead slugs
63 who designed that made it look exactly like x86_64 without
64 providing proper compile time symbols to test for it. as a result,
65 this detection cannot work reliably.
66 - valgrind stack registering was broken.
67 - do not rely on Time::HiRes anymore in Coro::Debug.
68
696.23 Fri Dec 7 23:36:37 CET 2012
70 - use experimental fiber implementation on native windows
71 perls.
72 - use sizeof (void *) as multiplication factor for stack sizes,
73 to accomodate the totally braindamaged microsoft 64 bit "os".
74 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
75 activeperl 5.16 crashes when PerlIO_define_layer is called due
76 to some bug in the perl dll, strawberry perl at least passes
77 the testsuite.
78 - implement Coro::Handle->peeraddr/host/port, for slightly
79 improved compatibility with LWP.
10 - implement 5.17 compatibility by almost blindly applying a 80 - implement 5.17 compatibility by almost blindly applying a
11 good-looking patch by Father Chrysostomos. 81 good-looking patch by Father Chrysostomos.
12 - use experimental fiber implementation on native windows 82 - move stack management functions into libcoro 3.
13 perls. 83 - libcoro version 3 "released".
14 - support magic values as timed_io_once args. 84 - support magic values as timed_io_once args.
15 - recommend AnyEvent 7+ or EV 4+, also require EV 85 - recommend AnyEvent 7+ or EV 4+, also require EV
