11 - Coro::SemaphoreSet->try did not actually work (analyzed by
12 SATO Kentaro).
13 - upgrade libecb to be C11 compliant.
9 14
156.41 Sat Sep 6 22:08:46 CEST 2014
16 - restore portability to perl 5.8.x.
17 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
18 up some memory, but fixes "use feature" and similar modules
19 when used inside a Coro.
20 - allow zero as argument to Coro::Channel to mean the same thing
21 as no argument. this works with older versions as well,
22 but wasn't legal until now.
23 - slightly better c header file detection.
24
256.39 Mon Jun 2 00:00:08 CEST 2014
26 - work around more incompatible changes in 5.20.
27
286.38 Sun Jun 1 21:54:23 CEST 2014
29 - check that perl slots actually have enough space to hold
30 interpreter variables.
31 - untested port to perl 5.19 (64 bit tmps indices) (reported
32 by Andreas König).
33 - croak when cancel is called without a thread context.
34
356.37 Tue Mar 4 13:27:33 CET 2014
36 - *sigh*, removed leftover debugging code from debugging a
37 perl bug, of all things.
38
396.36 Tue Mar 4 07:11:59 CET 2014
40 - semaphores would not clear the destroy hook when interrupted
41 by ->throw, causing segfaults or worse.
42 - ->throw on a thread waiting for a semaphore did not acquire
43 the semaphore, but also didn't wake up other waiters,
44 possibly causing a deadlock.
45 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
46 to report a full stacktrace, which should help find out
47 where the actual call is.
48 - "atomically" destroy data in slf_destroy, because it is
49 the right thing to do, just in case.
50 - disable ecb.h libm dependency, to compile on ancient systems
51 or under adverse conditions.
52
536.33 Mon Nov 18 11:26:27 CET 2013
54 - do not crash when freeing padlists with holes (in 5.18).
55 - tentative SVt_BIND 5.19 port/fix.
56
576.32 Tue Nov 5 15:35:35 CET 2013
58 - use a new algorithm to derive padlists for perl 5.18. The old
59 one could lead to 0-pointer accesses inside perl (reported
60 by Darin McBride).
61
626.31 Thu May 9 07:39:48 CEST 2013
63 - Coro::AIO requests would crash if the thread was ready'd
64 while the request was ongoing.
65
666.29 Wed May 8 02:55:18 CEST 2013
67 - when an on_destroy handler destructs the coro currently being
68 destructed a perl scalar could be accessed after being freed,
69 likely causing a crash.
70
716.28 Wed Mar 6 06:58:02 CET 2013
72 - clean remnants of existing __DIE__ and __WARN__ handlers so
73 they lose their magic and will not cause segfaults later
74 (testcase by Andrey Sagulin).
75 - improved Coro::State documentation a bit.
76 - Coro::Debug::command now flushes the output.
77 - add hack detection code for x32 abi, because the braindead slugs
78 who designed that made it look exactly like x86_64 without
79 providing proper compile time symbols to test for it. as a result,
80 this detection cannot work reliably.
81 - valgrind stack registering was broken.
82 - do not rely on Time::HiRes anymore in Coro::Debug.
83
846.23 Fri Dec 7 23:36:37 CET 2012
85 - use experimental fiber implementation on native windows
86 perls.
87 - use sizeof (void *) as multiplication factor for stack sizes,
88 to accomodate the totally braindamaged microsoft 64 bit "os".
89 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
90 activeperl 5.16 crashes when PerlIO_define_layer is called due
91 to some bug in the perl dll, strawberry perl at least passes
92 the testsuite.
93 - implement Coro::Handle->peeraddr/host/port, for slightly
94 improved compatibility with LWP.
95 - implement 5.17 compatibility by almost blindly applying a
96 good-looking patch by Father Chrysostomos.
97 - move stack management functions into libcoro 3.
98 - libcoro version 3 "released".
10 - support magic values as timed_io_once args. 99 - support magic values as timed_io_once args.
11 - recommend AnyEvent 7+ or EV 4+, also require EV 100 - recommend AnyEvent 7+ or EV 4+, also require EV
