8TODO: add peerhost/peerport from IO::Socket::INET etc. 10 - fix memory leak when Coro::Handle uses Coro::EV internally
11 (testcase by Sten Sten).
12 - update code to libev 4 API (internally, Coro still used the
13 version 3 API calls).
14 - remove unused hv_sig.
9 15
10 - bad things could happen in Coro::EV::timed_once if the arguments 166.47 Sat Jul 11 03:58:20 CEST 2015
17 - swap_svs - NVs can be in the SV head beginning with 5.20.
18
196.46 Tue Jun 30 14:36:30 CEST 2015
20 - restore portability to perls with windows fork emulation
21 (patch by Petr Písař).
22
236.45 Tue Jun 30 01:40:08 CEST 2015
24 - restore portability to perl 5.16 and below.
25
266.44 Tue Jun 30 00:41:54 CEST 2015
27 - avoid segfaulting (or worse) when tracing a canceled thread.
28 - the Event module silently broke it's public hook API, causing
29 failures on perls compiled with -Duselongdouble. Requiring
30 the latest version of Event because I don't know which release
31 changed this (it's not mentioned in the ChangeLog).
32 - allow xs level enterleave hooks via CoroAPI.
33
346.43 Thu Jun 4 15:38:14 CEST 2015
35 - use stability canary.
36 - port to stableperl-5.22.0-1.001.
37 - update libecb.
38
396.42 Wed Feb 11 20:29:52 CET 2015
40 - Coro::SemaphoreSet->try did not actually work (analyzed by
41 SATO Kentaro).
42 - upgrade libecb to be C11 compliant.
43
446.41 Sat Sep 6 22:08:46 CEST 2014
45 - restore portability to perl 5.8.x.
46 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
47 up some memory, but fixes "use feature" and similar modules
48 when used inside a Coro.
49 - allow zero as argument to Coro::Channel to mean the same thing
50 as no argument. this works with older versions as well,
51 but wasn't legal until now.
52 - slightly better c header file detection.
53
546.39 Mon Jun 2 00:00:08 CEST 2014
55 - work around more incompatible changes in 5.20.
56
576.38 Sun Jun 1 21:54:23 CEST 2014
58 - check that perl slots actually have enough space to hold
59 interpreter variables.
60 - untested port to perl 5.19 (64 bit tmps indices) (reported
61 by Andreas König).
62 - croak when cancel is called without a thread context.
63
646.37 Tue Mar 4 13:27:33 CET 2014
65 - *sigh*, removed leftover debugging code from debugging a
66 perl bug, of all things.
67
686.36 Tue Mar 4 07:11:59 CET 2014
69 - semaphores would not clear the destroy hook when interrupted
70 by ->throw, causing segfaults or worse.
71 - ->throw on a thread waiting for a semaphore did not acquire
72 the semaphore, but also didn't wake up other waiters,
73 possibly causing a deadlock.
74 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
75 to report a full stacktrace, which should help find out
76 where the actual call is.
77 - "atomically" destroy data in slf_destroy, because it is
78 the right thing to do, just in case.
79 - disable ecb.h libm dependency, to compile on ancient systems
80 or under adverse conditions.
81
826.33 Mon Nov 18 11:26:27 CET 2013
83 - do not crash when freeing padlists with holes (in 5.18).
84 - tentative SVt_BIND 5.19 port/fix.
85
866.32 Tue Nov 5 15:35:35 CET 2013
87 - use a new algorithm to derive padlists for perl 5.18. The old
88 one could lead to 0-pointer accesses inside perl (reported
89 by Darin McBride).
90
916.31 Thu May 9 07:39:48 CEST 2013
92 - Coro::AIO requests would crash if the thread was ready'd
93 while the request was ongoing.
94
956.29 Wed May 8 02:55:18 CEST 2013
96 - when an on_destroy handler destructs the coro currently being
97 destructed a perl scalar could be accessed after being freed,
98 likely causing a crash.
99
1006.28 Wed Mar 6 06:58:02 CET 2013
101 - clean remnants of existing __DIE__ and __WARN__ handlers so
102 they lose their magic and will not cause segfaults later
103 (testcase by Andrey Sagulin).
104 - improved Coro::State documentation a bit.
105 - Coro::Debug::command now flushes the output.
106 - add hack detection code for x32 abi, because the braindead slugs
107 who designed that made it look exactly like x86_64 without
108 providing proper compile time symbols to test for it. as a result,
109 this detection cannot work reliably.
110 - valgrind stack registering was broken.
111 - do not rely on Time::HiRes anymore in Coro::Debug.
112
1136.23 Fri Dec 7 23:36:37 CET 2012
114 - use experimental fiber implementation on native windows
115 perls.
116 - use sizeof (void *) as multiplication factor for stack sizes,
117 to accomodate the totally braindamaged microsoft 64 bit "os".
118 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
119 activeperl 5.16 crashes when PerlIO_define_layer is called due
120 to some bug in the perl dll, strawberry perl at least passes
121 the testsuite.
122 - implement Coro::Handle->peeraddr/host/port, for slightly
123 improved compatibility with LWP.
124 - implement 5.17 compatibility by almost blindly applying a
125 good-looking patch by Father Chrysostomos.
126 - move stack management functions into libcoro 3.
127 - libcoro version 3 "released".
11 were wrong. Also support magic values as timed_io_once args. 128 - support magic values as timed_io_once args.
12 - recommend AnyEvent 7+ or EV 4+, also require EV 129 - recommend AnyEvent 7+ or EV 4+, also require EV
13 version 4 or newer for Coro::EV. 130 version 4 or newer for Coro::EV.
