146.56 Thu Feb 20 19:40:07 CET 2020
15 - Coro::EV::time*once functions used ev_once, which is not cancelable.
16 This could cause problems due to I/O watchers not being stopped up
17 on exceptions/cancellation.
18
196.55 Fri Jul 19 17:28:09 CEST 2019
20 - Coro::RWLock woke up only one reader instead of all after a wrlock
21 (analyzed and patch by Maxim Skorobogatov).
22 - slightly improved documentation of Coro::RWLock and RWLock testcase.
23 - quickly (re)-ported to minix 3.3 before minix crashed again.
24
256.54 Sun Dec 16 11:06:07 CET 2018
26 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
27
286.53 Sun Dec 16 10:33:15 CET 2018
29 - the autogenerated prototypes of Coro::AIO now add ";" at the end
30 to avoid generating named unary operators and messing up parsing
31 (mostly affects aio_mlockall 4 | 8 which was parsed as
32 (aio_mlockall 4) | 8).
33 - do not use a prototype for select in Coro::Select, as CORE::select also
34 doesn't have one.
35
366.52 Tue Aug 14 18:49:43 CEST 2018
37 - libcoro update: allow sharing of coro threads using the pthreads
38 backend among different pthreads, as is required by Coro::Multicore.
39 - always allow ->call and ->eval when the coro is the current coroutine. this
40 makes it possible, among other things, to call these on $Coro::main.
41 - minor code cleanups.
42
436.514 Thu Aug 31 18:25:31 CEST 2017
44 - safe_cancel no longer croaks when called on already-destroyed
45 thread, but instead "just works".
46
476.513 Sat Jul 15 01:18:51 CEST 2017
48 - experimental 5.22 comaptibility changes (PadlistNAMES).
49 - removed attributes example and made sure the other examples
50 still work.
51 - fix some statevar types for newer perls, should be of no consequence.
52
536.512 Fri Jul 14 05:03:17 CEST 2017
54 - seems to pass test suite down till 5.8.9, so make this the
55 minimum requirement in Makefile.PL.
56 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
57 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
58 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
59 fortified longjmp variants in some libcs.
60 - re-try JIT allocation without PROT_EXEC, to hopefully improve
61 portability (still doesn't seem to work around broken selinux
62 mmap everywhere).
63 - speling fixes (Xavier Guimard).
64
656.511 Sun Jun 26 23:44:50 CEST 2016
66 - make it compile with threaded perls again.
67 - simplify and speed up __DIE__ and __WARN__ handling.
68
696.51 Sat Jun 25 20:57:20 CEST 2016
70 - 6.5 release didn't compile on most older perls due to
71 a logic error enabling experimental 5.24 code for all versions.
72 - since various broken or deficient patches float around
73 to work around the vtbl API breakage in perl, let's provide
74 our own workaround, which seems to be much less invasive
75 and more compatible than the approaches seen so far. YMMV.
76 - work around assertion failure in perl_destruct on 5.24
77 (analyzed by Dave Mitchell).
78
796.5 Wed Jun 22 22:23:50 CEST 2016
80 - swap_sv swapping order was not symmetrical, causing
81 wrong swaps when swap_sv was used multiple times on the
82 same sv in the same thread.
83 - swap_sv calls can now be undone by calling it again
84 with the same variables.
85 - swap_sv calls will now be undone in async_pool threads.
86 - split Coro::Semaphore::up/adjust into separate xs functions
87 for better error reporting, at slight codesize increase.
88 - (libcoro) arm assembly support, please test and report.
89 - adjust to PL_savestack changes in perl 5.24 (adapted from
90 the debian patch, which unfortunately gets it wrong).
91
926.49 Sat Oct 17 01:40:12 CEST 2015
93 - throwing an exception to a thread waiting in
94 Coro::Handle using Coro::EV did not stop the watchers,
95 causing the next call to fail (testcase by Martin Pritchard).
96 - bump minimum perl version to 5.10.
97
986.48 Sun Oct 4 19:03:51 CEST 2015
99 - fix memory leak when Coro::Handle uses Coro::EV internally
100 (testcase by Sten Sten).
101 - update code to libev 4 API (internally, Coro still used the
102 version 3 API calls).
103 - remove unused hv_sig.
104
1056.47 Sat Jul 11 03:58:20 CEST 2015
106 - swap_svs - NVs can be in the SV head beginning with 5.20.
107
1086.46 Tue Jun 30 14:36:30 CEST 2015
109 - restore portability to perls with windows fork emulation
110 (patch by Petr Písař).
111
1126.45 Tue Jun 30 01:40:08 CEST 2015
113 - restore portability to perl 5.16 and below.
114
1156.44 Tue Jun 30 00:41:54 CEST 2015
116 - avoid segfaulting (or worse) when tracing a canceled thread.
117 - the Event module silently broke it's public hook API, causing
118 failures on perls compiled with -Duselongdouble. Requiring
119 the latest version of Event because I don't know which release
120 changed this (it's not mentioned in the ChangeLog).
121 - allow xs level enterleave hooks via CoroAPI.
122
1236.43 Thu Jun 4 15:38:14 CEST 2015
124 - use stability canary.
125 - port to stableperl-5.22.0-1.001.
126 - update libecb.
127
1286.42 Wed Feb 11 20:29:52 CET 2015
129 - Coro::SemaphoreSet->try did not actually work (analyzed by
130 SATO Kentaro).
131 - upgrade libecb to be C11 compliant.
132
1336.41 Sat Sep 6 22:08:46 CEST 2014
134 - restore portability to perl 5.8.x.
135 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
136 up some memory, but fixes "use feature" and similar modules
137 when used inside a Coro.
138 - allow zero as argument to Coro::Channel to mean the same thing
139 as no argument. this works with older versions as well,
140 but wasn't legal until now.
141 - slightly better c header file detection.
142
1436.39 Mon Jun 2 00:00:08 CEST 2014
144 - work around more incompatible changes in 5.20.
145
1466.38 Sun Jun 1 21:54:23 CEST 2014
147 - check that perl slots actually have enough space to hold
148 interpreter variables.
149 - untested port to perl 5.19 (64 bit tmps indices) (reported
150 by Andreas König).
151 - croak when cancel is called without a thread context.
152
1536.37 Tue Mar 4 13:27:33 CET 2014
154 - *sigh*, removed leftover debugging code from debugging a
155 perl bug, of all things.
156
1576.36 Tue Mar 4 07:11:59 CET 2014
158 - semaphores would not clear the destroy hook when interrupted
159 by ->throw, causing segfaults or worse.
160 - ->throw on a thread waiting for a semaphore did not acquire
161 the semaphore, but also didn't wake up other waiters,
162 possibly causing a deadlock.
163 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
164 to report a full stacktrace, which should help find out
165 where the actual call is.
166 - "atomically" destroy data in slf_destroy, because it is
167 the right thing to do, just in case.
168 - disable ecb.h libm dependency, to compile on ancient systems
169 or under adverse conditions.
170
1716.33 Mon Nov 18 11:26:27 CET 2013
172 - do not crash when freeing padlists with holes (in 5.18).
9 - tentative SVt_BIND 5.19 port/fix. 173 - tentative SVt_BIND 5.19 port/fix.

116.32 Tue Nov 5 15:35:35 CET 2013 1756.32 Tue Nov 5 15:35:35 CET 2013
12 - use a new algorithm to derive padlists for perl 5.18. The old 176 - use a new algorithm to derive padlists for perl 5.18. The old
13 one could lead to 0-pointer accesses inside perl (reported 177 one could lead to 0-pointer accesses inside perl (reported

111 systems. 275 systems.

114 - workarounds are good, but the test for whether pthreads are used 278 - workarounds are good, but the test for whether pthreads are used
115 was not good. thisone should be better. 279 was not good. this one should be better.
116 - check differently whether gcc generates cfi instructions itself. 280 - check differently whether gcc generates cfi instructions itself.

120 destroyed and cleaned up automatically (e.g. async { schedule }). 284 destroyed and cleaned up automatically (e.g. async { schedule }).
121 - implement a JIT compiler for part of the thread switch code, 285 - implement a JIT compiler for part of the thread switch code,
122 which gives a 50% speed improvement on threaded perls, and 286 which gives a 50% speed improvement on threaded perls, and
123 about 4% on non-thraeded perls (so threaded perls now finally 287 about 4% on non-threaded perls (so threaded perls now finally
124 reach about half the speed of non-threaded perls). 288 reach about half the speed of non-threaded perls).
125 - slightly modernise Coro::Intro, add section about rouse functions. 289 - slightly modernise Coro::Intro, add section about rouse functions.
