17 - libcoro update: allow sharing of coro threads using the pthreads
18 backend among different pthreads, as is required by Coro::Multicore.
19 - always allow ->call and ->eval when the coro is the current coroutine. this
20 makes it possible, among other things, to call these on $Coro::main.
21 - minor code cleanups.
34 22
35TODO: warnhook reports from wrong line number now, when arg is Math::GMP number. 236.514 Thu Aug 31 18:25:31 CEST 2017
24 - safe_cancel no longer croaks when called on already-destroyed
25 thread, but instead "just works".
26
276.513 Sat Jul 15 01:18:51 CEST 2017
28 - experimental 5.22 comaptibility changes (PadlistNAMES).
29 - removed attributes example and made sure the other examples
30 still work.
31 - fix some statevar types for newer perls, should be of no consequence.
32
336.512 Fri Jul 14 05:03:17 CEST 2017
34 - seems to pass test suite down till 5.8.9, so make this the
35 minimum requirement in Makefile.PL.
36 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
37 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
38 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
39 fortified longjmp variants in some libcs.
40 - re-try JIT allocation without PROT_EXEC, to hopefully improve
41 portability (still doesn't seem to work around broken selinux
42 mmap everywhere).
43 - speling fixes (Xavier Guimard).
44
456.511 Sun Jun 26 23:44:50 CEST 2016
46 - make it compile with threaded perls again.
47 - simplify and speed up __DIE__ and __WARN__ handling.
48
496.51 Sat Jun 25 20:57:20 CEST 2016
50 - 6.5 release didn't compile on most older perls due to
51 a logic error enabling experimental 5.24 code for all versions.
52 - since various broken or deficient patches float around
53 to work around the vtbl API breakage in perl, let's provide
54 our own workaround, which seems to be much less invasive
55 and more compatible than the approaches seen so far. YMMV.
56 - work around assertion failure in perl_destruct on 5.24
57 (analyzed by Dave Mitchell).
58
596.5 Wed Jun 22 22:23:50 CEST 2016
60 - swap_sv swapping order was not symmetrical, causing
61 wrong swaps when swap_sv was used multiple times on the
62 same sv in the same thread.
63 - swap_sv calls can now be undone by calling it again
64 with the same variables.
65 - swap_sv calls will now be undone in async_pool threads.
66 - split Coro::Semaphore::up/adjust into separate xs functions
67 for better error reporting, at slight codesize increase.
68 - (libcoro) arm assembly support, please test and report.
69 - adjust to PL_savestack changes in perl 5.24 (adapted from
70 the debian patch, which unfortunately gets it wrong).
71
726.49 Sat Oct 17 01:40:12 CEST 2015
73 - throwing an exception to a thread waiting in
74 Coro::Handle using Coro::EV did not stop the watchers,
75 causing the next call to fail (testcase by Martin Pritchard).
76 - bump minimum perl version to 5.10.
77
786.48 Sun Oct 4 19:03:51 CEST 2015
79 - fix memory leak when Coro::Handle uses Coro::EV internally
80 (testcase by Sten Sten).
81 - update code to libev 4 API (internally, Coro still used the
82 version 3 API calls).
83 - remove unused hv_sig.
84
856.47 Sat Jul 11 03:58:20 CEST 2015
86 - swap_svs - NVs can be in the SV head beginning with 5.20.
87
886.46 Tue Jun 30 14:36:30 CEST 2015
89 - restore portability to perls with windows fork emulation
90 (patch by Petr Písař).
91
926.45 Tue Jun 30 01:40:08 CEST 2015
93 - restore portability to perl 5.16 and below.
94
956.44 Tue Jun 30 00:41:54 CEST 2015
96 - avoid segfaulting (or worse) when tracing a canceled thread.
97 - the Event module silently broke it's public hook API, causing
98 failures on perls compiled with -Duselongdouble. Requiring
99 the latest version of Event because I don't know which release
100 changed this (it's not mentioned in the ChangeLog).
101 - allow xs level enterleave hooks via CoroAPI.
102
1036.43 Thu Jun 4 15:38:14 CEST 2015
104 - use stability canary.
105 - port to stableperl-5.22.0-1.001.
106 - update libecb.
107
1086.42 Wed Feb 11 20:29:52 CET 2015
109 - Coro::SemaphoreSet->try did not actually work (analyzed by
110 SATO Kentaro).
111 - upgrade libecb to be C11 compliant.
112
1136.41 Sat Sep 6 22:08:46 CEST 2014
114 - restore portability to perl 5.8.x.
115 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
116 up some memory, but fixes "use feature" and similar modules
117 when used inside a Coro.
118 - allow zero as argument to Coro::Channel to mean the same thing
119 as no argument. this works with older versions as well,
120 but wasn't legal until now.
121 - slightly better c header file detection.
122
1236.39 Mon Jun 2 00:00:08 CEST 2014
124 - work around more incompatible changes in 5.20.
125
1266.38 Sun Jun 1 21:54:23 CEST 2014
127 - check that perl slots actually have enough space to hold
128 interpreter variables.
129 - untested port to perl 5.19 (64 bit tmps indices) (reported
130 by Andreas König).
131 - croak when cancel is called without a thread context.
132
1336.37 Tue Mar 4 13:27:33 CET 2014
134 - *sigh*, removed leftover debugging code from debugging a
135 perl bug, of all things.
136
1376.36 Tue Mar 4 07:11:59 CET 2014
138 - semaphores would not clear the destroy hook when interrupted
139 by ->throw, causing segfaults or worse.
140 - ->throw on a thread waiting for a semaphore did not acquire
141 the semaphore, but also didn't wake up other waiters,
142 possibly causing a deadlock.
36 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess 143 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
37 to report a full stacktrace, which should help find out 144 to report a full stacktrace, which should help find out
38 where the actual call is. 145 where the actual call is.

158 - implement a JIT compiler for part of the thread switch code, 265 - implement a JIT compiler for part of the thread switch code,
159 which gives a 50% speed improvement on threaded perls, and 266 which gives a 50% speed improvement on threaded perls, and
