8TODO: croak when async_pool tries to run canceled thread?
7 9
8TODO: add peerhost/peerport from IO::Socket::INET etc. 10 - avoid segfaulting (or worse) when tracing a canceled thread.
11 - the Event module silently broke it's public hook API, causing
12 failures on perls compiled with -Duselongdouble. Requiring
13 the latest version of Event because I don't know which release
14 changed this (it's not mentioned in the ChangeLog).
15 - allow xs level enterleave hooks via CoroAPI.
9 16
176.43 Thu Jun 4 15:38:14 CEST 2015
18 - use stability canary.
19 - port to stableperl-5.22.0-1.001.
20 - update libecb.
21
226.42 Wed Feb 11 20:29:52 CET 2015
23 - Coro::SemaphoreSet->try did not actually work (analyzed by
24 SATO Kentaro).
25 - upgrade libecb to be C11 compliant.
26
276.41 Sat Sep 6 22:08:46 CEST 2014
28 - restore portability to perl 5.8.x.
29 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
30 up some memory, but fixes "use feature" and similar modules
31 when used inside a Coro.
32 - allow zero as argument to Coro::Channel to mean the same thing
33 as no argument. this works with older versions as well,
34 but wasn't legal until now.
35 - slightly better c header file detection.
36
376.39 Mon Jun 2 00:00:08 CEST 2014
38 - work around more incompatible changes in 5.20.
39
406.38 Sun Jun 1 21:54:23 CEST 2014
41 - check that perl slots actually have enough space to hold
42 interpreter variables.
43 - untested port to perl 5.19 (64 bit tmps indices) (reported
44 by Andreas König).
45 - croak when cancel is called without a thread context.
46
476.37 Tue Mar 4 13:27:33 CET 2014
48 - *sigh*, removed leftover debugging code from debugging a
49 perl bug, of all things.
50
516.36 Tue Mar 4 07:11:59 CET 2014
52 - semaphores would not clear the destroy hook when interrupted
53 by ->throw, causing segfaults or worse.
54 - ->throw on a thread waiting for a semaphore did not acquire
55 the semaphore, but also didn't wake up other waiters,
56 possibly causing a deadlock.
57 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
58 to report a full stacktrace, which should help find out
59 where the actual call is.
60 - "atomically" destroy data in slf_destroy, because it is
61 the right thing to do, just in case.
62 - disable ecb.h libm dependency, to compile on ancient systems
63 or under adverse conditions.
64
656.33 Mon Nov 18 11:26:27 CET 2013
66 - do not crash when freeing padlists with holes (in 5.18).
67 - tentative SVt_BIND 5.19 port/fix.
68
696.32 Tue Nov 5 15:35:35 CET 2013
70 - use a new algorithm to derive padlists for perl 5.18. The old
71 one could lead to 0-pointer accesses inside perl (reported
72 by Darin McBride).
73
746.31 Thu May 9 07:39:48 CEST 2013
75 - Coro::AIO requests would crash if the thread was ready'd
76 while the request was ongoing.
77
786.29 Wed May 8 02:55:18 CEST 2013
79 - when an on_destroy handler destructs the coro currently being
80 destructed a perl scalar could be accessed after being freed,
81 likely causing a crash.
82
836.28 Wed Mar 6 06:58:02 CET 2013
84 - clean remnants of existing __DIE__ and __WARN__ handlers so
85 they lose their magic and will not cause segfaults later
86 (testcase by Andrey Sagulin).
87 - improved Coro::State documentation a bit.
88 - Coro::Debug::command now flushes the output.
89 - add hack detection code for x32 abi, because the braindead slugs
90 who designed that made it look exactly like x86_64 without
91 providing proper compile time symbols to test for it. as a result,
92 this detection cannot work reliably.
93 - valgrind stack registering was broken.
94 - do not rely on Time::HiRes anymore in Coro::Debug.
95
966.23 Fri Dec 7 23:36:37 CET 2012
97 - use experimental fiber implementation on native windows
98 perls.
99 - use sizeof (void *) as multiplication factor for stack sizes,
100 to accomodate the totally braindamaged microsoft 64 bit "os".
101 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
102 activeperl 5.16 crashes when PerlIO_define_layer is called due
103 to some bug in the perl dll, strawberry perl at least passes
104 the testsuite.
105 - implement Coro::Handle->peeraddr/host/port, for slightly
106 improved compatibility with LWP.
10 - implement 5.17 compatibility by almost blindly applying a 107 - implement 5.17 compatibility by almost blindly applying a
11 good-looking patch by Father Chrysostomos. 108 good-looking patch by Father Chrysostomos.

13 perls. 110 - libcoro version 3 "released".
14 - support magic values as timed_io_once args. 111 - support magic values as timed_io_once args.
15 - recommend AnyEvent 7+ or EV 4+, also require EV 112 - recommend AnyEvent 7+ or EV 4+, also require EV
