14#1 0x00007f638f0c0703 in slf_destroy (coro=0x5957180) at State.xs:2605 16 - allow rouse_wait to be called in a different thread.

226.56 Thu Feb 20 19:40:07 CET 2020
23 - Coro::EV::time*once functions used ev_once, which is not cancelable.
24 This could cause problems due to I/O watchers not being stopped up
25 on exceptions/cancellation.
34 26
35TODO: warnhook reports from wrong line number now, when arg is Math::GMP number. 276.55 Fri Jul 19 17:28:09 CEST 2019
28 - Coro::RWLock woke up only one reader instead of all after a wrlock
29 (analyzed and patch by Maxim Skorobogatov).
30 - slightly improved documentation of Coro::RWLock and RWLock testcase.
31 - quickly (re)-ported to minix 3.3 before minix crashed again.
32
336.54 Sun Dec 16 11:06:07 CET 2018
34 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
35
366.53 Sun Dec 16 10:33:15 CET 2018
37 - the autogenerated prototypes of Coro::AIO now add ";" at the end
38 to avoid generating named unary operators and messing up parsing
39 (mostly affects aio_mlockall 4 | 8 which was parsed as
40 (aio_mlockall 4) | 8).
41 - do not use a prototype for select in Coro::Select, as CORE::select also
42 doesn't have one.
43
446.52 Tue Aug 14 18:49:43 CEST 2018
45 - libcoro update: allow sharing of coro threads using the pthreads
46 backend among different pthreads, as is required by Coro::Multicore.
47 - always allow ->call and ->eval when the coro is the current coroutine. this
48 makes it possible, among other things, to call these on $Coro::main.
49 - minor code cleanups.
50
516.514 Thu Aug 31 18:25:31 CEST 2017
52 - safe_cancel no longer croaks when called on already-destroyed
53 thread, but instead "just works".
54
556.513 Sat Jul 15 01:18:51 CEST 2017
56 - experimental 5.22 comaptibility changes (PadlistNAMES).
57 - removed attributes example and made sure the other examples
58 still work.
59 - fix some statevar types for newer perls, should be of no consequence.
60
616.512 Fri Jul 14 05:03:17 CEST 2017
62 - seems to pass test suite down till 5.8.9, so make this the
63 minimum requirement in Makefile.PL.
64 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
65 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
66 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
67 fortified longjmp variants in some libcs.
68 - re-try JIT allocation without PROT_EXEC, to hopefully improve
69 portability (still doesn't seem to work around broken selinux
70 mmap everywhere).
71 - speling fixes (Xavier Guimard).
72
736.511 Sun Jun 26 23:44:50 CEST 2016
74 - make it compile with threaded perls again.
75 - simplify and speed up __DIE__ and __WARN__ handling.
76
776.51 Sat Jun 25 20:57:20 CEST 2016
78 - 6.5 release didn't compile on most older perls due to
79 a logic error enabling experimental 5.24 code for all versions.
80 - since various broken or deficient patches float around
81 to work around the vtbl API breakage in perl, let's provide
82 our own workaround, which seems to be much less invasive
83 and more compatible than the approaches seen so far. YMMV.
84 - work around assertion failure in perl_destruct on 5.24
85 (analyzed by Dave Mitchell).
86
876.5 Wed Jun 22 22:23:50 CEST 2016
88 - swap_sv swapping order was not symmetrical, causing
89 wrong swaps when swap_sv was used multiple times on the
90 same sv in the same thread.
91 - swap_sv calls can now be undone by calling it again
92 with the same variables.
93 - swap_sv calls will now be undone in async_pool threads.
94 - split Coro::Semaphore::up/adjust into separate xs functions
95 for better error reporting, at slight codesize increase.
96 - (libcoro) arm assembly support, please test and report.
97 - adjust to PL_savestack changes in perl 5.24 (adapted from
98 the debian patch, which unfortunately gets it wrong).
99
1006.49 Sat Oct 17 01:40:12 CEST 2015
101 - throwing an exception to a thread waiting in
102 Coro::Handle using Coro::EV did not stop the watchers,
103 causing the next call to fail (testcase by Martin Pritchard).
104 - bump minimum perl version to 5.10.
105
1066.48 Sun Oct 4 19:03:51 CEST 2015
107 - fix memory leak when Coro::Handle uses Coro::EV internally
108 (testcase by Sten Sten).
109 - update code to libev 4 API (internally, Coro still used the
110 version 3 API calls).
111 - remove unused hv_sig.
112
1136.47 Sat Jul 11 03:58:20 CEST 2015
114 - swap_svs - NVs can be in the SV head beginning with 5.20.
115
1166.46 Tue Jun 30 14:36:30 CEST 2015
117 - restore portability to perls with windows fork emulation
118 (patch by Petr Písař).
119
1206.45 Tue Jun 30 01:40:08 CEST 2015
121 - restore portability to perl 5.16 and below.
122
1236.44 Tue Jun 30 00:41:54 CEST 2015
124 - avoid segfaulting (or worse) when tracing a canceled thread.
125 - the Event module silently broke it's public hook API, causing
126 failures on perls compiled with -Duselongdouble. Requiring
127 the latest version of Event because I don't know which release
128 changed this (it's not mentioned in the ChangeLog).
129 - allow xs level enterleave hooks via CoroAPI.
130
1316.43 Thu Jun 4 15:38:14 CEST 2015
132 - use stability canary.
133 - port to stableperl-5.22.0-1.001.
134 - update libecb.
135
1366.42 Wed Feb 11 20:29:52 CET 2015
137 - Coro::SemaphoreSet->try did not actually work (analyzed by
138 SATO Kentaro).
139 - upgrade libecb to be C11 compliant.
140
1416.41 Sat Sep 6 22:08:46 CEST 2014
142 - restore portability to perl 5.8.x.
143 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
144 up some memory, but fixes "use feature" and similar modules
145 when used inside a Coro.
146 - allow zero as argument to Coro::Channel to mean the same thing
147 as no argument. this works with older versions as well,
148 but wasn't legal until now.
149 - slightly better c header file detection.
150
1516.39 Mon Jun 2 00:00:08 CEST 2014
152 - work around more incompatible changes in 5.20.
153
1546.38 Sun Jun 1 21:54:23 CEST 2014
155 - check that perl slots actually have enough space to hold
156 interpreter variables.
157 - untested port to perl 5.19 (64 bit tmps indices) (reported
158 by Andreas König).
159 - croak when cancel is called without a thread context.
160
1616.37 Tue Mar 4 13:27:33 CET 2014
162 - *sigh*, removed leftover debugging code from debugging a
163 perl bug, of all things.
164
1656.36 Tue Mar 4 07:11:59 CET 2014
166 - semaphores would not clear the destroy hook when interrupted
167 by ->throw, causing segfaults or worse.
168 - ->throw on a thread waiting for a semaphore did not acquire
169 the semaphore, but also didn't wake up other waiters,
170 possibly causing a deadlock.
36 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess 171 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
37 to report a full stacktrace, which should help find out 172 to report a full stacktrace, which should help find out
38 where the actual call is. 173 where the actual call is.

152 was not good. thisone should be better. 287 was not good. this one should be better.

156 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be 291 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
157 destroyed and cleaned up automatically (e.g. async { schedule }). 292 destroyed and cleaned up automatically (e.g. async { schedule }).
158 - implement a JIT compiler for part of the thread switch code, 293 - implement a JIT compiler for part of the thread switch code,
159 which gives a 50% speed improvement on threaded perls, and 294 which gives a 50% speed improvement on threaded perls, and
