11 - quickly (re)-ported to minix 3.3 before minix crashed again.
12
136.54 Sun Dec 16 11:06:07 CET 2018
14 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
15
166.53 Sun Dec 16 10:33:15 CET 2018
17 - the autogenerated prototypes of Coro::AIO now add ";" at the end
18 to avoid generating named unary operators and messing up parsing
19 (mostly affects aio_mlockall 4 | 8 which was parsed as
20 (aio_mlockall 4) | 8).
21 - do not use a prototype for select in Coro::Select, as CORE::select also
22 doesn't have one.
23
246.52 Tue Aug 14 18:49:43 CEST 2018
25 - libcoro update: allow sharing of coro threads using the pthreads
26 backend among different pthreads, as is required by Coro::Multicore.
27 - always allow ->call and ->eval when the coro is the current coroutine. this
28 makes it possible, among other things, to call these on $Coro::main.
29 - minor code cleanups.
30
316.514 Thu Aug 31 18:25:31 CEST 2017
32 - safe_cancel no longer croaks when called on already-destroyed
33 thread, but instead "just works".
34
356.513 Sat Jul 15 01:18:51 CEST 2017
36 - experimental 5.22 comaptibility changes (PadlistNAMES).
37 - removed attributes example and made sure the other examples
38 still work.
39 - fix some statevar types for newer perls, should be of no consequence.
40
416.512 Fri Jul 14 05:03:17 CEST 2017
42 - seems to pass test suite down till 5.8.9, so make this the
43 minimum requirement in Makefile.PL.
44 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
45 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
46 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
47 fortified longjmp variants in some libcs.
48 - re-try JIT allocation without PROT_EXEC, to hopefully improve
49 portability (still doesn't seem to work around broken selinux
50 mmap everywhere).
51 - speling fixes (Xavier Guimard).
52
536.511 Sun Jun 26 23:44:50 CEST 2016
54 - make it compile with threaded perls again.
55 - simplify and speed up __DIE__ and __WARN__ handling.
56
576.51 Sat Jun 25 20:57:20 CEST 2016
58 - 6.5 release didn't compile on most older perls due to
59 a logic error enabling experimental 5.24 code for all versions.
60 - since various broken or deficient patches float around
61 to work around the vtbl API breakage in perl, let's provide
62 our own workaround, which seems to be much less invasive
63 and more compatible than the approaches seen so far. YMMV.
64 - work around assertion failure in perl_destruct on 5.24
65 (analyzed by Dave Mitchell).
66
676.5 Wed Jun 22 22:23:50 CEST 2016
68 - swap_sv swapping order was not symmetrical, causing
69 wrong swaps when swap_sv was used multiple times on the
70 same sv in the same thread.
71 - swap_sv calls can now be undone by calling it again
72 with the same variables.
73 - swap_sv calls will now be undone in async_pool threads.
74 - split Coro::Semaphore::up/adjust into separate xs functions
75 for better error reporting, at slight codesize increase.
76 - (libcoro) arm assembly support, please test and report.
77 - adjust to PL_savestack changes in perl 5.24 (adapted from
78 the debian patch, which unfortunately gets it wrong).
79
806.49 Sat Oct 17 01:40:12 CEST 2015
81 - throwing an exception to a thread waiting in
82 Coro::Handle using Coro::EV did not stop the watchers,
83 causing the next call to fail (testcase by Martin Pritchard).
84 - bump minimum perl version to 5.10.
85
866.48 Sun Oct 4 19:03:51 CEST 2015
87 - fix memory leak when Coro::Handle uses Coro::EV internally
88 (testcase by Sten Sten).
89 - update code to libev 4 API (internally, Coro still used the
90 version 3 API calls).
91 - remove unused hv_sig.
92
936.47 Sat Jul 11 03:58:20 CEST 2015
94 - swap_svs - NVs can be in the SV head beginning with 5.20.
95
966.46 Tue Jun 30 14:36:30 CEST 2015
97 - restore portability to perls with windows fork emulation
98 (patch by Petr Písař).
99
1006.45 Tue Jun 30 01:40:08 CEST 2015
101 - restore portability to perl 5.16 and below.
102
1036.44 Tue Jun 30 00:41:54 CEST 2015
104 - avoid segfaulting (or worse) when tracing a canceled thread.
105 - the Event module silently broke it's public hook API, causing
106 failures on perls compiled with -Duselongdouble. Requiring
107 the latest version of Event because I don't know which release
108 changed this (it's not mentioned in the ChangeLog).
109 - allow xs level enterleave hooks via CoroAPI.
110
1116.43 Thu Jun 4 15:38:14 CEST 2015
112 - use stability canary.
113 - port to stableperl-5.22.0-1.001.
114 - update libecb.
115
1166.42 Wed Feb 11 20:29:52 CET 2015
117 - Coro::SemaphoreSet->try did not actually work (analyzed by
118 SATO Kentaro).
119 - upgrade libecb to be C11 compliant.
120
1216.41 Sat Sep 6 22:08:46 CEST 2014
122 - restore portability to perl 5.8.x.
123 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
124 up some memory, but fixes "use feature" and similar modules
125 when used inside a Coro.
126 - allow zero as argument to Coro::Channel to mean the same thing
127 as no argument. this works with older versions as well,
128 but wasn't legal until now.
129 - slightly better c header file detection.
130
1316.39 Mon Jun 2 00:00:08 CEST 2014
132 - work around more incompatible changes in 5.20.
133
1346.38 Sun Jun 1 21:54:23 CEST 2014
135 - check that perl slots actually have enough space to hold
136 interpreter variables.
137 - untested port to perl 5.19 (64 bit tmps indices) (reported
138 by Andreas König).
139 - croak when cancel is called without a thread context.
140
1416.37 Tue Mar 4 13:27:33 CET 2014
142 - *sigh*, removed leftover debugging code from debugging a
143 perl bug, of all things.
144
1456.36 Tue Mar 4 07:11:59 CET 2014
146 - semaphores would not clear the destroy hook when interrupted
147 by ->throw, causing segfaults or worse.
148 - ->throw on a thread waiting for a semaphore did not acquire
149 the semaphore, but also didn't wake up other waiters,
150 possibly causing a deadlock.
151 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
152 to report a full stacktrace, which should help find out
153 where the actual call is.
154 - "atomically" destroy data in slf_destroy, because it is
155 the right thing to do, just in case.
156 - disable ecb.h libm dependency, to compile on ancient systems
157 or under adverse conditions.
158
1596.33 Mon Nov 18 11:26:27 CET 2013
160 - do not crash when freeing padlists with holes (in 5.18).
161 - tentative SVt_BIND 5.19 port/fix.
8 162
96.32 Tue Nov 5 15:35:35 CET 2013 1636.32 Tue Nov 5 15:35:35 CET 2013
10 - use a new algorithm to derive padlists for perl 5.18. The old 164 - use a new algorithm to derive padlists for perl 5.18. The old
11 one could lead to 0-pointer accesses inside perl (reported 165 one could lead to 0-pointer accesses inside perl (reported
12 by Darin McBride). 166 by Darin McBride).

108 handle and barfed. now it's just a bit slower on gentoo and similar 262 handle and barfed. now it's just a bit slower on gentoo and similar
109 systems. 263 systems.

113 was not good. thisone should be better. 267 was not good. this one should be better.
114 - check differently whether gcc generates cfi instructions itself. 268 - check differently whether gcc generates cfi instructions itself.

117 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be 271 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
118 destroyed and cleaned up automatically (e.g. async { schedule }). 272 destroyed and cleaned up automatically (e.g. async { schedule }).
119 - implement a JIT compiler for part of the thread switch code, 273 - implement a JIT compiler for part of the thread switch code,
120 which gives a 50% speed improvement on threaded perls, and 274 which gives a 50% speed improvement on threaded perls, and
121 about 4% on non-thraeded perls (so threaded perls now finally 275 about 4% on non-threaded perls (so threaded perls now finally
122 reach about half the speed of non-threaded perls). 276 reach about half the speed of non-threaded perls).
123 - slightly modernise Coro::Intro, add section about rouse functions. 277 - slightly modernise Coro::Intro, add section about rouse functions.
