10#0 coro_semaphore_adjust (av=0x0, adjust=0) at State.xs:2915 10 to work around the vtbl API breakage in perl, let's provide
112915 State.xs: No such file or directory. 11 out own workaround, which seems to be much less invasive
12(gdb) bt 12 and more compatible than the approaches seen so far. YMMV.

17 - swap_sv swapping order was not symmetrical, causing
18 wrong swaps when swap_sv was used multiple times on the
19 same sv in the same thread.
20 - swap_sv calls can now be undone by calling it again
21 with the same variables.
22 - swap_sv calls will now be undone in async_pool threads.
23 - split Coro::Semaphore::up/adjust into separate xs functions
24 for better error reporting, at slight codesize increase.
25 - (libcoro) arm assembly support, please test and report.
26 - adjust to PL_savestack changes in perl 5.24 (adapted from
27 the debian patch, which unfortunately gets it wrong).
34 28
35TODO: warnhook reports from wrong line number now, when arg is Math::GMP number. 296.49 Sat Oct 17 01:40:12 CEST 2015
30 - throwing an exception to a thread waiting in
31 Coro::Handle using Coro::EV did not stop the watchers,
32 causing the next call to fail (testcase by Martin Pritchard).
33 - bump minimum perl version to 5.10.
34
356.48 Sun Oct 4 19:03:51 CEST 2015
36 - fix memory leak when Coro::Handle uses Coro::EV internally
37 (testcase by Sten Sten).
38 - update code to libev 4 API (internally, Coro still used the
39 version 3 API calls).
40 - remove unused hv_sig.
41
426.47 Sat Jul 11 03:58:20 CEST 2015
43 - swap_svs - NVs can be in the SV head beginning with 5.20.
44
456.46 Tue Jun 30 14:36:30 CEST 2015
46 - restore portability to perls with windows fork emulation
47 (patch by Petr Písař).
48
496.45 Tue Jun 30 01:40:08 CEST 2015
50 - restore portability to perl 5.16 and below.
51
526.44 Tue Jun 30 00:41:54 CEST 2015
53 - avoid segfaulting (or worse) when tracing a canceled thread.
54 - the Event module silently broke it's public hook API, causing
55 failures on perls compiled with -Duselongdouble. Requiring
56 the latest version of Event because I don't know which release
57 changed this (it's not mentioned in the ChangeLog).
58 - allow xs level enterleave hooks via CoroAPI.
59
606.43 Thu Jun 4 15:38:14 CEST 2015
61 - use stability canary.
62 - port to stableperl-5.22.0-1.001.
63 - update libecb.
64
656.42 Wed Feb 11 20:29:52 CET 2015
66 - Coro::SemaphoreSet->try did not actually work (analyzed by
67 SATO Kentaro).
68 - upgrade libecb to be C11 compliant.
69
706.41 Sat Sep 6 22:08:46 CEST 2014
71 - restore portability to perl 5.8.x.
72 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
73 up some memory, but fixes "use feature" and similar modules
74 when used inside a Coro.
75 - allow zero as argument to Coro::Channel to mean the same thing
76 as no argument. this works with older versions as well,
77 but wasn't legal until now.
78 - slightly better c header file detection.
79
806.39 Mon Jun 2 00:00:08 CEST 2014
81 - work around more incompatible changes in 5.20.
82
836.38 Sun Jun 1 21:54:23 CEST 2014
84 - check that perl slots actually have enough space to hold
85 interpreter variables.
86 - untested port to perl 5.19 (64 bit tmps indices) (reported
87 by Andreas König).
88 - croak when cancel is called without a thread context.
89
906.37 Tue Mar 4 13:27:33 CET 2014
91 - *sigh*, removed leftover debugging code from debugging a
92 perl bug, of all things.
93
946.36 Tue Mar 4 07:11:59 CET 2014
95 - semaphores would not clear the destroy hook when interrupted
96 by ->throw, causing segfaults or worse.
97 - ->throw on a thread waiting for a semaphore did not acquire
98 the semaphore, but also didn't wake up other waiters,
99 possibly causing a deadlock.
36 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess 100 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
37 to report a full stacktrace, which should help find out 101 to report a full stacktrace, which should help find out
