8TODO: add peerhost/peerport from IO::Socket::INET etc. 10 - restore portability to perl 5.8.x.
9 11
10 - bad things could happen in Coro::EV::timed_once if the arguments 126.39 Mon Jun 2 00:00:08 CEST 2014
13 - work around more incompatible changes in 5.20.
14
156.38 Sun Jun 1 21:54:23 CEST 2014
16 - check that perl slots actually have enough space to hold
17 interpreter variables.
18 - untested port to perl 5.19 (64 bit tmps indices) (reported
19 by Andreas König).
20 - croak when cancel is called without a thread context.
21
226.37 Tue Mar 4 13:27:33 CET 2014
23 - *sigh*, removed leftover debugging code from debugging a
24 perl bug, of all things.
25
266.36 Tue Mar 4 07:11:59 CET 2014
27 - semaphores would not clear the destroy hook when interrupted
28 by ->throw, causing segfaults or worse.
29 - ->throw on a thread waiting for a semaphore did not acquire
30 the semaphore, but also didn't wake up other waiters,
31 possibly causing a deadlock.
32 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
33 to report a full stacktrace, which should help find out
34 where the actual call is.
35 - "atomically" destroy data in slf_destroy, because it is
36 the right thing to do, just in case.
37 - disable ecb.h libm dependency, to compile on ancient systems
38 or under adverse conditions.
39
406.33 Mon Nov 18 11:26:27 CET 2013
41 - do not crash when freeing padlists with holes (in 5.18).
42 - tentative SVt_BIND 5.19 port/fix.
43
446.32 Tue Nov 5 15:35:35 CET 2013
45 - use a new algorithm to derive padlists for perl 5.18. The old
46 one could lead to 0-pointer accesses inside perl (reported
47 by Darin McBride).
48
496.31 Thu May 9 07:39:48 CEST 2013
50 - Coro::AIO requests would crash if the thread was ready'd
51 while the request was ongoing.
52
536.29 Wed May 8 02:55:18 CEST 2013
54 - when an on_destroy handler destructs the coro currently being
55 destructed a perl scalar could be accessed after being freed,
56 likely causing a crash.
57
586.28 Wed Mar 6 06:58:02 CET 2013
59 - clean remnants of existing __DIE__ and __WARN__ handlers so
60 they lose their magic and will not cause segfaults later
61 (testcase by Andrey Sagulin).
62 - improved Coro::State documentation a bit.
63 - Coro::Debug::command now flushes the output.
64 - add hack detection code for x32 abi, because the braindead slugs
65 who designed that made it look exactly like x86_64 without
66 providing proper compile time symbols to test for it. as a result,
67 this detection cannot work reliably.
68 - valgrind stack registering was broken.
69 - do not rely on Time::HiRes anymore in Coro::Debug.
70
716.23 Fri Dec 7 23:36:37 CET 2012
72 - use experimental fiber implementation on native windows
73 perls.
74 - use sizeof (void *) as multiplication factor for stack sizes,
75 to accomodate the totally braindamaged microsoft 64 bit "os".
76 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
77 activeperl 5.16 crashes when PerlIO_define_layer is called due
78 to some bug in the perl dll, strawberry perl at least passes
79 the testsuite.
80 - implement Coro::Handle->peeraddr/host/port, for slightly
81 improved compatibility with LWP.
82 - implement 5.17 compatibility by almost blindly applying a
83 good-looking patch by Father Chrysostomos.
84 - move stack management functions into libcoro 3.
85 - libcoro version 3 "released".
11 were wrong. Also support magic values as timed_io_once args. 86 - support magic values as timed_io_once args.
12 - recommend AnyEvent 7+ or EV 4+, also require EV 87 - recommend AnyEvent 7+ or EV 4+, also require EV
13 version 4 or newer for Coro::EV. 88 version 4 or newer for Coro::EV.
