30 - potential fix for an interesting type of recursive coro
31 destruction (testcase by Christopher J. Madsen).
32 - change jit executable strategy, to hopefully appease more
33 hardened environments.
34
356.57 Wed Jul 29 15:08:44 CEST 2020
36 - override AnyEvent condvar methods "properly", as AnyEvent
37 has support for pluggable condvars since 2011. This also
38 avoids problems with recursive waits by avoiding to mix
39 impl methods with coro code.
40 - allow rouse_wait to be called in a different thread.
41 - slightly clarify rouse_cb/rouse_wait documentation.
42 - slightly improve rouse callback performance and memory usage.
43 - try to report correct calller when throwing exception in
44 on $condvar->recv, not a useless line in Coro::AnyEvent.
45
466.56 Thu Feb 20 19:40:07 CET 2020
47 - Coro::EV::time*once functions used ev_once, which is not cancelable.
48 This could cause problems due to I/O watchers not being stopped up
49 on exceptions/cancellation.
50
516.55 Fri Jul 19 17:28:09 CEST 2019
52 - Coro::RWLock woke up only one reader instead of all after a wrlock
53 (analyzed and patch by Maxim Skorobogatov).
54 - slightly improved documentation of Coro::RWLock and RWLock testcase.
55 - quickly (re)-ported to minix 3.3 before minix crashed again.
56
576.54 Sun Dec 16 11:06:07 CET 2018
58 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
59
606.53 Sun Dec 16 10:33:15 CET 2018
61 - the autogenerated prototypes of Coro::AIO now add ";" at the end
62 to avoid generating named unary operators and messing up parsing
63 (mostly affects aio_mlockall 4 | 8 which was parsed as
64 (aio_mlockall 4) | 8).
65 - do not use a prototype for select in Coro::Select, as CORE::select also
66 doesn't have one.
67
686.52 Tue Aug 14 18:49:43 CEST 2018
69 - libcoro update: allow sharing of coro threads using the pthreads
70 backend among different pthreads, as is required by Coro::Multicore.
71 - always allow ->call and ->eval when the coro is the current coroutine. this
72 makes it possible, among other things, to call these on $Coro::main.
73 - minor code cleanups.
74
756.514 Thu Aug 31 18:25:31 CEST 2017
76 - safe_cancel no longer croaks when called on already-destroyed
77 thread, but instead "just works".
78
796.513 Sat Jul 15 01:18:51 CEST 2017
80 - experimental 5.22 comaptibility changes (PadlistNAMES).
81 - removed attributes example and made sure the other examples
82 still work.
83 - fix some statevar types for newer perls, should be of no consequence.
84
856.512 Fri Jul 14 05:03:17 CEST 2017
86 - seems to pass test suite down till 5.8.9, so make this the
87 minimum requirement in Makefile.PL.
88 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
89 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
90 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
91 fortified longjmp variants in some libcs.
92 - re-try JIT allocation without PROT_EXEC, to hopefully improve
93 portability (still doesn't seem to work around broken selinux
94 mmap everywhere).
95 - speling fixes (Xavier Guimard).
96
976.511 Sun Jun 26 23:44:50 CEST 2016
98 - make it compile with threaded perls again.
99 - simplify and speed up __DIE__ and __WARN__ handling.
100
1016.51 Sat Jun 25 20:57:20 CEST 2016
102 - 6.5 release didn't compile on most older perls due to
103 a logic error enabling experimental 5.24 code for all versions.
104 - since various broken or deficient patches float around
105 to work around the vtbl API breakage in perl, let's provide
106 our own workaround, which seems to be much less invasive
107 and more compatible than the approaches seen so far. YMMV.
108 - work around assertion failure in perl_destruct on 5.24
109 (analyzed by Dave Mitchell).
110
1116.5 Wed Jun 22 22:23:50 CEST 2016
112 - swap_sv swapping order was not symmetrical, causing
113 wrong swaps when swap_sv was used multiple times on the
114 same sv in the same thread.
115 - swap_sv calls can now be undone by calling it again
116 with the same variables.
117 - swap_sv calls will now be undone in async_pool threads.
118 - split Coro::Semaphore::up/adjust into separate xs functions
119 for better error reporting, at slight codesize increase.
120 - (libcoro) arm assembly support, please test and report.
121 - adjust to PL_savestack changes in perl 5.24 (adapted from
122 the debian patch, which unfortunately gets it wrong).
123
1246.49 Sat Oct 17 01:40:12 CEST 2015
125 - throwing an exception to a thread waiting in
126 Coro::Handle using Coro::EV did not stop the watchers,
127 causing the next call to fail (testcase by Martin Pritchard).
128 - bump minimum perl version to 5.10.
129
1306.48 Sun Oct 4 19:03:51 CEST 2015
131 - fix memory leak when Coro::Handle uses Coro::EV internally
132 (testcase by Sten Sten).
133 - update code to libev 4 API (internally, Coro still used the
134 version 3 API calls).
135 - remove unused hv_sig.
136
1376.47 Sat Jul 11 03:58:20 CEST 2015
138 - swap_svs - NVs can be in the SV head beginning with 5.20.
139
1406.46 Tue Jun 30 14:36:30 CEST 2015
141 - restore portability to perls with windows fork emulation
142 (patch by Petr Písař).
143
1446.45 Tue Jun 30 01:40:08 CEST 2015
145 - restore portability to perl 5.16 and below.
146
1476.44 Tue Jun 30 00:41:54 CEST 2015
148 - avoid segfaulting (or worse) when tracing a canceled thread.
149 - the Event module silently broke it's public hook API, causing
150 failures on perls compiled with -Duselongdouble. Requiring
151 the latest version of Event because I don't know which release
152 changed this (it's not mentioned in the ChangeLog).
153 - allow xs level enterleave hooks via CoroAPI.
154
1556.43 Thu Jun 4 15:38:14 CEST 2015
156 - use stability canary.
157 - port to stableperl-5.22.0-1.001.
158 - update libecb.
159
1606.42 Wed Feb 11 20:29:52 CET 2015
161 - Coro::SemaphoreSet->try did not actually work (analyzed by
162 SATO Kentaro).
163 - upgrade libecb to be C11 compliant.
164
1656.41 Sat Sep 6 22:08:46 CEST 2014
10 - restore portability to perl 5.8.x. 166 - restore portability to perl 5.8.x.
167 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
168 up some memory, but fixes "use feature" and similar modules
169 when used inside a Coro.
11 - allow zero as agrument to Coro::Channel to mean the same thing 170 - allow zero as argument to Coro::Channel to mean the same thing
12 as no argument. this works with older versions as well, 171 as no argument. this works with older versions as well,
13 but wasn't legal until now. 172 but wasn't legal until now.
173 - slightly better c header file detection.
14 174
156.39 Mon Jun 2 00:00:08 CEST 2014 1756.39 Mon Jun 2 00:00:08 CEST 2014
16 - work around more incompatible changes in 5.20. 176 - work around more incompatible changes in 5.20.
17 177
186.38 Sun Jun 1 21:54:23 CEST 2014 1786.38 Sun Jun 1 21:54:23 CEST 2014
