32 - override AnyEvent condvar methods "properly", as AnyEvent
33 has support for pluggable condvars since 2011. This also
34 avoids problems with recursive waits by avoiding to mix
35 impl methods with coro code.
36 - allow rouse_wait to be called in a different thread.
37 - slightly clarify rouse_cb/rouse_wait documentation.
38 - slightly improve rouse callback performance and memory usage.
39 - try to report correct calller when throwing exception in
40 on $condvar->recv, not a useless line in Coro::AnyEvent.
41
426.56 Thu Feb 20 19:40:07 CET 2020
43 - Coro::EV::time*once functions used ev_once, which is not cancelable.
44 This could cause problems due to I/O watchers not being stopped up
45 on exceptions/cancellation.
46
476.55 Fri Jul 19 17:28:09 CEST 2019
48 - Coro::RWLock woke up only one reader instead of all after a wrlock
49 (analyzed and patch by Maxim Skorobogatov).
50 - slightly improved documentation of Coro::RWLock and RWLock testcase.
51 - quickly (re)-ported to minix 3.3 before minix crashed again.
52
536.54 Sun Dec 16 11:06:07 CET 2018
54 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
55
566.53 Sun Dec 16 10:33:15 CET 2018
57 - the autogenerated prototypes of Coro::AIO now add ";" at the end
58 to avoid generating named unary operators and messing up parsing
59 (mostly affects aio_mlockall 4 | 8 which was parsed as
60 (aio_mlockall 4) | 8).
61 - do not use a prototype for select in Coro::Select, as CORE::select also
62 doesn't have one.
63
646.52 Tue Aug 14 18:49:43 CEST 2018
65 - libcoro update: allow sharing of coro threads using the pthreads
66 backend among different pthreads, as is required by Coro::Multicore.
67 - always allow ->call and ->eval when the coro is the current coroutine. this
68 makes it possible, among other things, to call these on $Coro::main.
69 - minor code cleanups.
70
716.514 Thu Aug 31 18:25:31 CEST 2017
72 - safe_cancel no longer croaks when called on already-destroyed
73 thread, but instead "just works".
74
756.513 Sat Jul 15 01:18:51 CEST 2017
76 - experimental 5.22 comaptibility changes (PadlistNAMES).
77 - removed attributes example and made sure the other examples
78 still work.
79 - fix some statevar types for newer perls, should be of no consequence.
80
816.512 Fri Jul 14 05:03:17 CEST 2017
82 - seems to pass test suite down till 5.8.9, so make this the
83 minimum requirement in Makefile.PL.
84 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
85 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
86 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
87 fortified longjmp variants in some libcs.
88 - re-try JIT allocation without PROT_EXEC, to hopefully improve
89 portability (still doesn't seem to work around broken selinux
90 mmap everywhere).
91 - speling fixes (Xavier Guimard).
92
936.511 Sun Jun 26 23:44:50 CEST 2016
94 - make it compile with threaded perls again.
95 - simplify and speed up __DIE__ and __WARN__ handling.
96
976.51 Sat Jun 25 20:57:20 CEST 2016
98 - 6.5 release didn't compile on most older perls due to
99 a logic error enabling experimental 5.24 code for all versions.
100 - since various broken or deficient patches float around
101 to work around the vtbl API breakage in perl, let's provide
102 our own workaround, which seems to be much less invasive
103 and more compatible than the approaches seen so far. YMMV.
104 - work around assertion failure in perl_destruct on 5.24
105 (analyzed by Dave Mitchell).
106
1076.5 Wed Jun 22 22:23:50 CEST 2016
108 - swap_sv swapping order was not symmetrical, causing
109 wrong swaps when swap_sv was used multiple times on the
110 same sv in the same thread.
111 - swap_sv calls can now be undone by calling it again
112 with the same variables.
113 - swap_sv calls will now be undone in async_pool threads.
114 - split Coro::Semaphore::up/adjust into separate xs functions
115 for better error reporting, at slight codesize increase.
116 - (libcoro) arm assembly support, please test and report.
117 - adjust to PL_savestack changes in perl 5.24 (adapted from
118 the debian patch, which unfortunately gets it wrong).
119
1206.49 Sat Oct 17 01:40:12 CEST 2015
121 - throwing an exception to a thread waiting in
122 Coro::Handle using Coro::EV did not stop the watchers,
123 causing the next call to fail (testcase by Martin Pritchard).
12 - bump minimum perl version to 5.10. 124 - bump minimum perl version to 5.10.
13 125
146.48 Sun Oct 4 19:03:51 CEST 2015 1266.48 Sun Oct 4 19:03:51 CEST 2015
15 - fix memory leak when Coro::Handle uses Coro::EV internally 127 - fix memory leak when Coro::Handle uses Coro::EV internally
16 (testcase by Sten Sten). 128 (testcase by Sten Sten).
