30 - potential fix for an interetsing type of recursive coro
31 destruction (testcase by Christopher J. Madsen).
32
336.57 Wed Jul 29 15:08:44 CEST 2020
34 - override AnyEvent condvar methods "properly", as AnyEvent
35 has support for pluggable condvars since 2011. This also
36 avoids problems with recursive waits by avoiding to mix
37 impl methods with coro code.
38 - allow rouse_wait to be called in a different thread.
39 - slightly clarify rouse_cb/rouse_wait documentation.
40 - slightly improve rouse callback performance and memory usage.
41 - try to report correct calller when throwing exception in
42 on $condvar->recv, not a useless line in Coro::AnyEvent.
43
446.56 Thu Feb 20 19:40:07 CET 2020
45 - Coro::EV::time*once functions used ev_once, which is not cancelable.
46 This could cause problems due to I/O watchers not being stopped up
47 on exceptions/cancellation.
48
496.55 Fri Jul 19 17:28:09 CEST 2019
50 - Coro::RWLock woke up only one reader instead of all after a wrlock
51 (analyzed and patch by Maxim Skorobogatov).
52 - slightly improved documentation of Coro::RWLock and RWLock testcase.
53 - quickly (re)-ported to minix 3.3 before minix crashed again.
54
556.54 Sun Dec 16 11:06:07 CET 2018
56 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
57
586.53 Sun Dec 16 10:33:15 CET 2018
59 - the autogenerated prototypes of Coro::AIO now add ";" at the end
60 to avoid generating named unary operators and messing up parsing
61 (mostly affects aio_mlockall 4 | 8 which was parsed as
62 (aio_mlockall 4) | 8).
63 - do not use a prototype for select in Coro::Select, as CORE::select also
64 doesn't have one.
65
666.52 Tue Aug 14 18:49:43 CEST 2018
67 - libcoro update: allow sharing of coro threads using the pthreads
68 backend among different pthreads, as is required by Coro::Multicore.
69 - always allow ->call and ->eval when the coro is the current coroutine. this
70 makes it possible, among other things, to call these on $Coro::main.
71 - minor code cleanups.
72
736.514 Thu Aug 31 18:25:31 CEST 2017
74 - safe_cancel no longer croaks when called on already-destroyed
75 thread, but instead "just works".
76
776.513 Sat Jul 15 01:18:51 CEST 2017
78 - experimental 5.22 comaptibility changes (PadlistNAMES).
79 - removed attributes example and made sure the other examples
80 still work.
81 - fix some statevar types for newer perls, should be of no consequence.
82
836.512 Fri Jul 14 05:03:17 CEST 2017
84 - seems to pass test suite down till 5.8.9, so make this the
85 minimum requirement in Makefile.PL.
86 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
87 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
88 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
89 fortified longjmp variants in some libcs.
90 - re-try JIT allocation without PROT_EXEC, to hopefully improve
91 portability (still doesn't seem to work around broken selinux
92 mmap everywhere).
93 - speling fixes (Xavier Guimard).
94
956.511 Sun Jun 26 23:44:50 CEST 2016
96 - make it compile with threaded perls again.
97 - simplify and speed up __DIE__ and __WARN__ handling.
98
996.51 Sat Jun 25 20:57:20 CEST 2016
100 - 6.5 release didn't compile on most older perls due to
101 a logic error enabling experimental 5.24 code for all versions.
102 - since various broken or deficient patches float around
103 to work around the vtbl API breakage in perl, let's provide
104 our own workaround, which seems to be much less invasive
105 and more compatible than the approaches seen so far. YMMV.
106 - work around assertion failure in perl_destruct on 5.24
107 (analyzed by Dave Mitchell).
108
1096.5 Wed Jun 22 22:23:50 CEST 2016
110 - swap_sv swapping order was not symmetrical, causing
111 wrong swaps when swap_sv was used multiple times on the
112 same sv in the same thread.
113 - swap_sv calls can now be undone by calling it again
114 with the same variables.
115 - swap_sv calls will now be undone in async_pool threads.
116 - split Coro::Semaphore::up/adjust into separate xs functions
117 for better error reporting, at slight codesize increase.
118 - (libcoro) arm assembly support, please test and report.
119 - adjust to PL_savestack changes in perl 5.24 (adapted from
120 the debian patch, which unfortunately gets it wrong).
121
1226.49 Sat Oct 17 01:40:12 CEST 2015
123 - throwing an exception to a thread waiting in
124 Coro::Handle using Coro::EV did not stop the watchers,
125 causing the next call to fail (testcase by Martin Pritchard).
126 - bump minimum perl version to 5.10.
127
1286.48 Sun Oct 4 19:03:51 CEST 2015
129 - fix memory leak when Coro::Handle uses Coro::EV internally
130 (testcase by Sten Sten).
131 - update code to libev 4 API (internally, Coro still used the
132 version 3 API calls).
133 - remove unused hv_sig.
134
1356.47 Sat Jul 11 03:58:20 CEST 2015
136 - swap_svs - NVs can be in the SV head beginning with 5.20.
137
1386.46 Tue Jun 30 14:36:30 CEST 2015
139 - restore portability to perls with windows fork emulation
140 (patch by Petr Písař).
141
1426.45 Tue Jun 30 01:40:08 CEST 2015
143 - restore portability to perl 5.16 and below.
144
1456.44 Tue Jun 30 00:41:54 CEST 2015
146 - avoid segfaulting (or worse) when tracing a canceled thread.
147 - the Event module silently broke it's public hook API, causing
148 failures on perls compiled with -Duselongdouble. Requiring
149 the latest version of Event because I don't know which release
150 changed this (it's not mentioned in the ChangeLog).
151 - allow xs level enterleave hooks via CoroAPI.
152
1536.43 Thu Jun 4 15:38:14 CEST 2015
154 - use stability canary.
155 - port to stableperl-5.22.0-1.001.
156 - update libecb.
157
1586.42 Wed Feb 11 20:29:52 CET 2015
159 - Coro::SemaphoreSet->try did not actually work (analyzed by
160 SATO Kentaro).
161 - upgrade libecb to be C11 compliant.
162
1636.41 Sat Sep 6 22:08:46 CEST 2014
164 - restore portability to perl 5.8.x.
165 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
166 up some memory, but fixes "use feature" and similar modules
167 when used inside a Coro.
168 - allow zero as argument to Coro::Channel to mean the same thing
169 as no argument. this works with older versions as well,
170 but wasn't legal until now.
171 - slightly better c header file detection.
172
1736.39 Mon Jun 2 00:00:08 CEST 2014
174 - work around more incompatible changes in 5.20.
175
1766.38 Sun Jun 1 21:54:23 CEST 2014
177 - check that perl slots actually have enough space to hold
178 interpreter variables.
179 - untested port to perl 5.19 (64 bit tmps indices) (reported
180 by Andreas König).
9 - croak when cancel is called without a thread context. 181 - croak when cancel is called without a thread context.

137 was not good. thisone should be better. 309 was not good. this one should be better.
138 - check differently whether gcc generates cfi instructions itself. 310 - check differently whether gcc generates cfi instructions itself.

142 destroyed and cleaned up automatically (e.g. async { schedule }). 314 destroyed and cleaned up automatically (e.g. async { schedule }).
143 - implement a JIT compiler for part of the thread switch code, 315 - implement a JIT compiler for part of the thread switch code,
144 which gives a 50% speed improvement on threaded perls, and 316 which gives a 50% speed improvement on threaded perls, and
145 about 4% on non-thraeded perls (so threaded perls now finally 317 about 4% on non-threaded perls (so threaded perls now finally
146 reach about half the speed of non-threaded perls). 318 reach about half the speed of non-threaded perls).
