136.56 Thu Feb 20 19:40:07 CET 2020
14 - Coro::EV::time*once functions used ev_once, which is not cancelable.
15 This could cause problems due to I/O watchers not being stopped up
16 on exceptions/cancellation.
17
186.55 Fri Jul 19 17:28:09 CEST 2019
19 - Coro::RWLock woke up only one reader instead of all after a wrlock
20 (analyzed and patch by Maxim Skorobogatov).
21 - slightly improved documentation of Coro::RWLock and RWLock testcase.
22 - quickly (re)-ported to minix 3.3 before minix crashed again.
23
246.54 Sun Dec 16 11:06:07 CET 2018
25 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
26
276.53 Sun Dec 16 10:33:15 CET 2018
28 - the autogenerated prototypes of Coro::AIO now add ";" at the end
29 to avoid generating named unary operators and messing up parsing
30 (mostly affects aio_mlockall 4 | 8 which was parsed as
31 (aio_mlockall 4) | 8).
32 - do not use a prototype for select in Coro::Select, as CORE::select also
33 doesn't have one.
34
356.52 Tue Aug 14 18:49:43 CEST 2018
36 - libcoro update: allow sharing of coro threads using the pthreads
37 backend among different pthreads, as is required by Coro::Multicore.
38 - always allow ->call and ->eval when the coro is the current coroutine. this
39 makes it possible, among other things, to call these on $Coro::main.
40 - minor code cleanups.
41
426.514 Thu Aug 31 18:25:31 CEST 2017
43 - safe_cancel no longer croaks when called on already-destroyed
44 thread, but instead "just works".
45
466.513 Sat Jul 15 01:18:51 CEST 2017
47 - experimental 5.22 comaptibility changes (PadlistNAMES).
48 - removed attributes example and made sure the other examples
49 still work.
50 - fix some statevar types for newer perls, should be of no consequence.
51
526.512 Fri Jul 14 05:03:17 CEST 2017
53 - seems to pass test suite down till 5.8.9, so make this the
54 minimum requirement in Makefile.PL.
55 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
56 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
57 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
58 fortified longjmp variants in some libcs.
59 - re-try JIT allocation without PROT_EXEC, to hopefully improve
60 portability (still doesn't seem to work around broken selinux
61 mmap everywhere).
62 - speling fixes (Xavier Guimard).
63
646.511 Sun Jun 26 23:44:50 CEST 2016
65 - make it compile with threaded perls again.
66 - simplify and speed up __DIE__ and __WARN__ handling.
67
686.51 Sat Jun 25 20:57:20 CEST 2016
69 - 6.5 release didn't compile on most older perls due to
70 a logic error enabling experimental 5.24 code for all versions.
71 - since various broken or deficient patches float around
72 to work around the vtbl API breakage in perl, let's provide
73 our own workaround, which seems to be much less invasive
74 and more compatible than the approaches seen so far. YMMV.
75 - work around assertion failure in perl_destruct on 5.24
76 (analyzed by Dave Mitchell).
77
786.5 Wed Jun 22 22:23:50 CEST 2016
79 - swap_sv swapping order was not symmetrical, causing
80 wrong swaps when swap_sv was used multiple times on the
81 same sv in the same thread.
82 - swap_sv calls can now be undone by calling it again
83 with the same variables.
84 - swap_sv calls will now be undone in async_pool threads.
85 - split Coro::Semaphore::up/adjust into separate xs functions
86 for better error reporting, at slight codesize increase.
87 - (libcoro) arm assembly support, please test and report.
88 - adjust to PL_savestack changes in perl 5.24 (adapted from
89 the debian patch, which unfortunately gets it wrong).
90
916.49 Sat Oct 17 01:40:12 CEST 2015
92 - throwing an exception to a thread waiting in
93 Coro::Handle using Coro::EV did not stop the watchers,
94 causing the next call to fail (testcase by Martin Pritchard).
95 - bump minimum perl version to 5.10.
96
976.48 Sun Oct 4 19:03:51 CEST 2015
98 - fix memory leak when Coro::Handle uses Coro::EV internally
99 (testcase by Sten Sten).
100 - update code to libev 4 API (internally, Coro still used the
101 version 3 API calls).
102 - remove unused hv_sig.
103
1046.47 Sat Jul 11 03:58:20 CEST 2015
105 - swap_svs - NVs can be in the SV head beginning with 5.20.
106
1076.46 Tue Jun 30 14:36:30 CEST 2015
108 - restore portability to perls with windows fork emulation
109 (patch by Petr Písař).
110
1116.45 Tue Jun 30 01:40:08 CEST 2015
112 - restore portability to perl 5.16 and below.
113
1146.44 Tue Jun 30 00:41:54 CEST 2015
115 - avoid segfaulting (or worse) when tracing a canceled thread.
116 - the Event module silently broke it's public hook API, causing
117 failures on perls compiled with -Duselongdouble. Requiring
118 the latest version of Event because I don't know which release
119 changed this (it's not mentioned in the ChangeLog).
120 - allow xs level enterleave hooks via CoroAPI.
121
1226.43 Thu Jun 4 15:38:14 CEST 2015
123 - use stability canary.
124 - port to stableperl-5.22.0-1.001.
125 - update libecb.
126
1276.42 Wed Feb 11 20:29:52 CET 2015
128 - Coro::SemaphoreSet->try did not actually work (analyzed by
129 SATO Kentaro).
130 - upgrade libecb to be C11 compliant.
131
1326.41 Sat Sep 6 22:08:46 CEST 2014
133 - restore portability to perl 5.8.x.
134 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
135 up some memory, but fixes "use feature" and similar modules
136 when used inside a Coro.
137 - allow zero as argument to Coro::Channel to mean the same thing
138 as no argument. this works with older versions as well,
139 but wasn't legal until now.
140 - slightly better c header file detection.
141
1426.39 Mon Jun 2 00:00:08 CEST 2014
143 - work around more incompatible changes in 5.20.
144
1456.38 Sun Jun 1 21:54:23 CEST 2014
146 - check that perl slots actually have enough space to hold
147 interpreter variables.
148 - untested port to perl 5.19 (64 bit tmps indices) (reported
149 by Andreas König).
150 - croak when cancel is called without a thread context.
151
1526.37 Tue Mar 4 13:27:33 CET 2014
153 - *sigh*, removed leftover debugging code from debugging a
154 perl bug, of all things.
155
1566.36 Tue Mar 4 07:11:59 CET 2014
157 - semaphores would not clear the destroy hook when interrupted
158 by ->throw, causing segfaults or worse.
159 - ->throw on a thread waiting for a semaphore did not acquire
160 the semaphore, but also didn't wake up other waiters,
161 possibly causing a deadlock.
162 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
163 to report a full stacktrace, which should help find out
164 where the actual call is.
165 - "atomically" destroy data in slf_destroy, because it is
166 the right thing to do, just in case.
167 - disable ecb.h libm dependency, to compile on ancient systems
168 or under adverse conditions.
169
1706.33 Mon Nov 18 11:26:27 CET 2013
171 - do not crash when freeing padlists with holes (in 5.18).
9 - tentative SVt_BIND 5.19 port/fix. 172 - tentative SVt_BIND 5.19 port/fix.

116.32 Tue Nov 5 15:35:35 CET 2013 1746.32 Tue Nov 5 15:35:35 CET 2013
12 - use a new algorithm to derive padlists for perl 5.18. The old 175 - use a new algorithm to derive padlists for perl 5.18. The old
13 one could lead to 0-pointer accesses inside perl (reported 176 one could lead to 0-pointer accesses inside perl (reported

115 was not good. thisone should be better. 278 was not good. this one should be better.
116 - check differently whether gcc generates cfi instructions itself. 279 - check differently whether gcc generates cfi instructions itself.

121 - implement a JIT compiler for part of the thread switch code, 284 - implement a JIT compiler for part of the thread switch code,
122 which gives a 50% speed improvement on threaded perls, and 285 which gives a 50% speed improvement on threaded perls, and

124 reach about half the speed of non-threaded perls). 287 reach about half the speed of non-threaded perls).
125 - slightly modernise Coro::Intro, add section about rouse functions. 288 - slightly modernise Coro::Intro, add section about rouse functions.
