136.57
14 - override AnyEvent condvar methods "properly", as AnyEvent
15 has support for pluggable condvars since 2011. This also
16 avoids problems with recursive waits by avoiding to mix
17 impl methods with coro code.
18 - allow rouse_wait to be called in a different thread.
19 - slightly clarify rouse_cb/rouse_wait documentation.
20 - slightly improve rouse callback performance and memory usage.
21 - try to report correct calller when throwing exception in
22 on $condvar->recv, not a useless line in Coro::AnyEvent.
23
246.56 Thu Feb 20 19:40:07 CET 2020
25 - Coro::EV::time*once functions used ev_once, which is not cancelable.
26 This could cause problems due to I/O watchers not being stopped up
27 on exceptions/cancellation.
28
296.55 Fri Jul 19 17:28:09 CEST 2019
30 - Coro::RWLock woke up only one reader instead of all after a wrlock
31 (analyzed and patch by Maxim Skorobogatov).
32 - slightly improved documentation of Coro::RWLock and RWLock testcase.
33 - quickly (re)-ported to minix 3.3 before minix crashed again.
34
356.54 Sun Dec 16 11:06:07 CET 2018
36 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
37
386.53 Sun Dec 16 10:33:15 CET 2018
39 - the autogenerated prototypes of Coro::AIO now add ";" at the end
40 to avoid generating named unary operators and messing up parsing
41 (mostly affects aio_mlockall 4 | 8 which was parsed as
42 (aio_mlockall 4) | 8).
43 - do not use a prototype for select in Coro::Select, as CORE::select also
44 doesn't have one.
45
466.52 Tue Aug 14 18:49:43 CEST 2018
47 - libcoro update: allow sharing of coro threads using the pthreads
48 backend among different pthreads, as is required by Coro::Multicore.
49 - always allow ->call and ->eval when the coro is the current coroutine. this
50 makes it possible, among other things, to call these on $Coro::main.
51 - minor code cleanups.
52
536.514 Thu Aug 31 18:25:31 CEST 2017
54 - safe_cancel no longer croaks when called on already-destroyed
55 thread, but instead "just works".
56
576.513 Sat Jul 15 01:18:51 CEST 2017
58 - experimental 5.22 comaptibility changes (PadlistNAMES).
59 - removed attributes example and made sure the other examples
60 still work.
61 - fix some statevar types for newer perls, should be of no consequence.
62
636.512 Fri Jul 14 05:03:17 CEST 2017
64 - seems to pass test suite down till 5.8.9, so make this the
65 minimum requirement in Makefile.PL.
66 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
67 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
68 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
69 fortified longjmp variants in some libcs.
70 - re-try JIT allocation without PROT_EXEC, to hopefully improve
71 portability (still doesn't seem to work around broken selinux
72 mmap everywhere).
73 - speling fixes (Xavier Guimard).
74
756.511 Sun Jun 26 23:44:50 CEST 2016
76 - make it compile with threaded perls again.
77 - simplify and speed up __DIE__ and __WARN__ handling.
78
796.51 Sat Jun 25 20:57:20 CEST 2016
80 - 6.5 release didn't compile on most older perls due to
81 a logic error enabling experimental 5.24 code for all versions.
82 - since various broken or deficient patches float around
83 to work around the vtbl API breakage in perl, let's provide
84 our own workaround, which seems to be much less invasive
85 and more compatible than the approaches seen so far. YMMV.
86 - work around assertion failure in perl_destruct on 5.24
87 (analyzed by Dave Mitchell).
88
896.5 Wed Jun 22 22:23:50 CEST 2016
90 - swap_sv swapping order was not symmetrical, causing
91 wrong swaps when swap_sv was used multiple times on the
92 same sv in the same thread.
93 - swap_sv calls can now be undone by calling it again
94 with the same variables.
95 - swap_sv calls will now be undone in async_pool threads.
96 - split Coro::Semaphore::up/adjust into separate xs functions
97 for better error reporting, at slight codesize increase.
98 - (libcoro) arm assembly support, please test and report.
99 - adjust to PL_savestack changes in perl 5.24 (adapted from
100 the debian patch, which unfortunately gets it wrong).
101
1026.49 Sat Oct 17 01:40:12 CEST 2015
103 - throwing an exception to a thread waiting in
104 Coro::Handle using Coro::EV did not stop the watchers,
105 causing the next call to fail (testcase by Martin Pritchard).
106 - bump minimum perl version to 5.10.
107
1086.48 Sun Oct 4 19:03:51 CEST 2015
109 - fix memory leak when Coro::Handle uses Coro::EV internally
110 (testcase by Sten Sten).
111 - update code to libev 4 API (internally, Coro still used the
112 version 3 API calls).
113 - remove unused hv_sig.
114
1156.47 Sat Jul 11 03:58:20 CEST 2015
116 - swap_svs - NVs can be in the SV head beginning with 5.20.
117
1186.46 Tue Jun 30 14:36:30 CEST 2015
119 - restore portability to perls with windows fork emulation
120 (patch by Petr Písař).
121
1226.45 Tue Jun 30 01:40:08 CEST 2015
123 - restore portability to perl 5.16 and below.
124
1256.44 Tue Jun 30 00:41:54 CEST 2015
126 - avoid segfaulting (or worse) when tracing a canceled thread.
127 - the Event module silently broke it's public hook API, causing
128 failures on perls compiled with -Duselongdouble. Requiring
129 the latest version of Event because I don't know which release
130 changed this (it's not mentioned in the ChangeLog).
131 - allow xs level enterleave hooks via CoroAPI.
132
1336.43 Thu Jun 4 15:38:14 CEST 2015
134 - use stability canary.
135 - port to stableperl-5.22.0-1.001.
136 - update libecb.
137
1386.42 Wed Feb 11 20:29:52 CET 2015
139 - Coro::SemaphoreSet->try did not actually work (analyzed by
140 SATO Kentaro).
141 - upgrade libecb to be C11 compliant.
142
1436.41 Sat Sep 6 22:08:46 CEST 2014
144 - restore portability to perl 5.8.x.
145 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
146 up some memory, but fixes "use feature" and similar modules
147 when used inside a Coro.
148 - allow zero as argument to Coro::Channel to mean the same thing
149 as no argument. this works with older versions as well,
150 but wasn't legal until now.
151 - slightly better c header file detection.
152
1536.39 Mon Jun 2 00:00:08 CEST 2014
154 - work around more incompatible changes in 5.20.
155
1566.38 Sun Jun 1 21:54:23 CEST 2014
157 - check that perl slots actually have enough space to hold
158 interpreter variables.
159 - untested port to perl 5.19 (64 bit tmps indices) (reported
160 by Andreas König).
161 - croak when cancel is called without a thread context.
162
1636.37 Tue Mar 4 13:27:33 CET 2014
164 - *sigh*, removed leftover debugging code from debugging a
165 perl bug, of all things.
166
1676.36 Tue Mar 4 07:11:59 CET 2014
168 - semaphores would not clear the destroy hook when interrupted
169 by ->throw, causing segfaults or worse.
170 - ->throw on a thread waiting for a semaphore did not acquire
171 the semaphore, but also didn't wake up other waiters,
172 possibly causing a deadlock.
173 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
174 to report a full stacktrace, which should help find out
175 where the actual call is.
176 - "atomically" destroy data in slf_destroy, because it is
177 the right thing to do, just in case.
178 - disable ecb.h libm dependency, to compile on ancient systems
179 or under adverse conditions.
180
1816.33 Mon Nov 18 11:26:27 CET 2013
182 - do not crash when freeing padlists with holes (in 5.18).
183 - tentative SVt_BIND 5.19 port/fix.
184
1856.32 Tue Nov 5 15:35:35 CET 2013
9 - use a new algorithm to derive padlists for perl 5.18. The old 186 - use a new algorithm to derive padlists for perl 5.18. The old
10 one could lead to 0-pointer accesses inside perl. 187 one could lead to 0-pointer accesses inside perl (reported
188 by Darin McBride).

117 - implement a JIT compiler for part of the thread switch code, 295 - implement a JIT compiler for part of the thread switch code,
118 which gives a 50% speed improvement on threaded perls, and 296 which gives a 50% speed improvement on threaded perls, and
119 about 4% on non-thraeded perls (so threaded perls now finally 297 about 4% on non-threaded perls (so threaded perls now finally
120 reach about half the speed of non-threaded perls). 298 reach about half the speed of non-threaded perls).
121 - slightly modernise Coro::Intro, add section about rouse functions. 299 - slightly modernise Coro::Intro, add section about rouse functions.
