12
13 - Coro::EV::time*once functions used ev_once, which is not cancelable.
14 This could cause problems due to I/O watchers not being stopped up
15 on exceptions/cancellation.
16
176.55 Fri Jul 19 17:28:09 CEST 2019
18 - Coro::RWLock woke up only one reader instead of all after a wrlock
19 (analyzed and patch by Maxim Skorobogatov).
20 - slightly improved documentation of Coro::RWLock and RWLock testcase.
21 - quickly (re)-ported to minix 3.3 before minix crashed again.
22
236.54 Sun Dec 16 11:06:07 CET 2018
24 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
25
266.53 Sun Dec 16 10:33:15 CET 2018
27 - the autogenerated prototypes of Coro::AIO now add ";" at the end
28 to avoid generating named unary operators and messing up parsing
29 (mostly affects aio_mlockall 4 | 8 which was parsed as
30 (aio_mlockall 4) | 8).
31 - do not use a prototype for select in Coro::Select, as CORE::select also
32 doesn't have one.
33
346.52 Tue Aug 14 18:49:43 CEST 2018
35 - libcoro update: allow sharing of coro threads using the pthreads
36 backend among different pthreads, as is required by Coro::Multicore.
37 - always allow ->call and ->eval when the coro is the current coroutine. this
38 makes it possible, among other things, to call these on $Coro::main.
39 - minor code cleanups.
40
416.514 Thu Aug 31 18:25:31 CEST 2017
42 - safe_cancel no longer croaks when called on already-destroyed
43 thread, but instead "just works".
44
456.513 Sat Jul 15 01:18:51 CEST 2017
46 - experimental 5.22 comaptibility changes (PadlistNAMES).
47 - removed attributes example and made sure the other examples
48 still work.
49 - fix some statevar types for newer perls, should be of no consequence.
50
516.512 Fri Jul 14 05:03:17 CEST 2017
52 - seems to pass test suite down till 5.8.9, so make this the
53 minimum requirement in Makefile.PL.
54 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
55 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
56 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
57 fortified longjmp variants in some libcs.
58 - re-try JIT allocation without PROT_EXEC, to hopefully improve
59 portability (still doesn't seem to work around broken selinux
60 mmap everywhere).
61 - speling fixes (Xavier Guimard).
62
636.511 Sun Jun 26 23:44:50 CEST 2016
64 - make it compile with threaded perls again.
65 - simplify and speed up __DIE__ and __WARN__ handling.
66
676.51 Sat Jun 25 20:57:20 CEST 2016
68 - 6.5 release didn't compile on most older perls due to
69 a logic error enabling experimental 5.24 code for all versions.
70 - since various broken or deficient patches float around
71 to work around the vtbl API breakage in perl, let's provide
72 our own workaround, which seems to be much less invasive
73 and more compatible than the approaches seen so far. YMMV.
74 - work around assertion failure in perl_destruct on 5.24
75 (analyzed by Dave Mitchell).
76
776.5 Wed Jun 22 22:23:50 CEST 2016
78 - swap_sv swapping order was not symmetrical, causing
79 wrong swaps when swap_sv was used multiple times on the
80 same sv in the same thread.
81 - swap_sv calls can now be undone by calling it again
82 with the same variables.
83 - swap_sv calls will now be undone in async_pool threads.
84 - split Coro::Semaphore::up/adjust into separate xs functions
85 for better error reporting, at slight codesize increase.
86 - (libcoro) arm assembly support, please test and report.
87 - adjust to PL_savestack changes in perl 5.24 (adapted from
88 the debian patch, which unfortunately gets it wrong).
89
906.49 Sat Oct 17 01:40:12 CEST 2015
91 - throwing an exception to a thread waiting in
92 Coro::Handle using Coro::EV did not stop the watchers,
93 causing the next call to fail (testcase by Martin Pritchard).
94 - bump minimum perl version to 5.10.
95
966.48 Sun Oct 4 19:03:51 CEST 2015
97 - fix memory leak when Coro::Handle uses Coro::EV internally
98 (testcase by Sten Sten).
99 - update code to libev 4 API (internally, Coro still used the
100 version 3 API calls).
101 - remove unused hv_sig.
102
1036.47 Sat Jul 11 03:58:20 CEST 2015
104 - swap_svs - NVs can be in the SV head beginning with 5.20.
105
1066.46 Tue Jun 30 14:36:30 CEST 2015
107 - restore portability to perls with windows fork emulation
108 (patch by Petr Písař).
109
1106.45 Tue Jun 30 01:40:08 CEST 2015
111 - restore portability to perl 5.16 and below.
112
1136.44 Tue Jun 30 00:41:54 CEST 2015
114 - avoid segfaulting (or worse) when tracing a canceled thread.
115 - the Event module silently broke it's public hook API, causing
116 failures on perls compiled with -Duselongdouble. Requiring
117 the latest version of Event because I don't know which release
118 changed this (it's not mentioned in the ChangeLog).
119 - allow xs level enterleave hooks via CoroAPI.
120
1216.43 Thu Jun 4 15:38:14 CEST 2015
122 - use stability canary.
123 - port to stableperl-5.22.0-1.001.
124 - update libecb.
125
1266.42 Wed Feb 11 20:29:52 CET 2015
127 - Coro::SemaphoreSet->try did not actually work (analyzed by
128 SATO Kentaro).
129 - upgrade libecb to be C11 compliant.
130
1316.41 Sat Sep 6 22:08:46 CEST 2014
132 - restore portability to perl 5.8.x.
133 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
134 up some memory, but fixes "use feature" and similar modules
135 when used inside a Coro.
136 - allow zero as argument to Coro::Channel to mean the same thing
137 as no argument. this works with older versions as well,
138 but wasn't legal until now.
139 - slightly better c header file detection.
140
1416.39 Mon Jun 2 00:00:08 CEST 2014
142 - work around more incompatible changes in 5.20.
143
1446.38 Sun Jun 1 21:54:23 CEST 2014
145 - check that perl slots actually have enough space to hold
146 interpreter variables.
147 - untested port to perl 5.19 (64 bit tmps indices) (reported
148 by Andreas König).
149 - croak when cancel is called without a thread context.
150
1516.37 Tue Mar 4 13:27:33 CET 2014
152 - *sigh*, removed leftover debugging code from debugging a
153 perl bug, of all things.
154
1556.36 Tue Mar 4 07:11:59 CET 2014
156 - semaphores would not clear the destroy hook when interrupted
157 by ->throw, causing segfaults or worse.
158 - ->throw on a thread waiting for a semaphore did not acquire
159 the semaphore, but also didn't wake up other waiters,
160 possibly causing a deadlock.
161 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
162 to report a full stacktrace, which should help find out
163 where the actual call is.
164 - "atomically" destroy data in slf_destroy, because it is
165 the right thing to do, just in case.
166 - disable ecb.h libm dependency, to compile on ancient systems
167 or under adverse conditions.
168
1696.33 Mon Nov 18 11:26:27 CET 2013
170 - do not crash when freeing padlists with holes (in 5.18).
171 - tentative SVt_BIND 5.19 port/fix.
8 172
96.32 Tue Nov 5 15:35:35 CET 2013 1736.32 Tue Nov 5 15:35:35 CET 2013
10 - use a new algorithm to derive padlists for perl 5.18. The old 174 - use a new algorithm to derive padlists for perl 5.18. The old
11 one could lead to 0-pointer accesses inside perl (reported 175 one could lead to 0-pointer accesses inside perl (reported
12 by Darin McBride). 176 by Darin McBride).

108 handle and barfed. now it's just a bit slower on gentoo and similar 272 handle and barfed. now it's just a bit slower on gentoo and similar
109 systems. 273 systems.

113 was not good. thisone should be better. 277 was not good. this one should be better.
114 - check differently whether gcc generates cfi instructions itself. 278 - check differently whether gcc generates cfi instructions itself.

117 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be 281 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
118 destroyed and cleaned up automatically (e.g. async { schedule }). 282 destroyed and cleaned up automatically (e.g. async { schedule }).
119 - implement a JIT compiler for part of the thread switch code, 283 - implement a JIT compiler for part of the thread switch code,
120 which gives a 50% speed improvement on threaded perls, and 284 which gives a 50% speed improvement on threaded perls, and
121 about 4% on non-thraeded perls (so threaded perls now finally 285 about 4% on non-threaded perls (so threaded perls now finally
122 reach about half the speed of non-threaded perls). 286 reach about half the speed of non-threaded perls).
123 - slightly modernise Coro::Intro, add section about rouse functions. 287 - slightly modernise Coro::Intro, add section about rouse functions.
