28};
29
30 - potential fix for an interesting type of recursive coro
31 destruction (testcase by Christopher J. Madsen).
32 - add connected method as alias for peername in Coro::Handle, as
33 the inherited version does not work for us (analyzed by Simon816).
34 - change jit executable strategy, to hopefully appease more
35 hardened environments.
36
376.57 Wed Jul 29 15:08:44 CEST 2020
38 - override AnyEvent condvar methods "properly", as AnyEvent
39 has support for pluggable condvars since 2011. This also
40 avoids problems with recursive waits by avoiding to mix
41 impl methods with coro code.
42 - allow rouse_wait to be called in a different thread.
43 - slightly clarify rouse_cb/rouse_wait documentation.
44 - slightly improve rouse callback performance and memory usage.
45 - try to report correct calller when throwing exception in
46 on $condvar->recv, not a useless line in Coro::AnyEvent.
47
486.56 Thu Feb 20 19:40:07 CET 2020
49 - Coro::EV::time*once functions used ev_once, which is not cancelable.
50 This could cause problems due to I/O watchers not being stopped up
51 on exceptions/cancellation.
52
536.55 Fri Jul 19 17:28:09 CEST 2019
54 - Coro::RWLock woke up only one reader instead of all after a wrlock
55 (analyzed and patch by Maxim Skorobogatov).
56 - slightly improved documentation of Coro::RWLock and RWLock testcase.
57 - quickly (re)-ported to minix 3.3 before minix crashed again.
58
596.54 Sun Dec 16 11:06:07 CET 2018
60 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
61
626.53 Sun Dec 16 10:33:15 CET 2018
63 - the autogenerated prototypes of Coro::AIO now add ";" at the end
64 to avoid generating named unary operators and messing up parsing
65 (mostly affects aio_mlockall 4 | 8 which was parsed as
66 (aio_mlockall 4) | 8).
67 - do not use a prototype for select in Coro::Select, as CORE::select also
68 doesn't have one.
69
706.52 Tue Aug 14 18:49:43 CEST 2018
71 - libcoro update: allow sharing of coro threads using the pthreads
72 backend among different pthreads, as is required by Coro::Multicore.
73 - always allow ->call and ->eval when the coro is the current coroutine. this
74 makes it possible, among other things, to call these on $Coro::main.
75 - minor code cleanups.
76
776.514 Thu Aug 31 18:25:31 CEST 2017
78 - safe_cancel no longer croaks when called on already-destroyed
79 thread, but instead "just works".
80
816.513 Sat Jul 15 01:18:51 CEST 2017
82 - experimental 5.22 comaptibility changes (PadlistNAMES).
83 - removed attributes example and made sure the other examples
84 still work.
85 - fix some statevar types for newer perls, should be of no consequence.
86
876.512 Fri Jul 14 05:03:17 CEST 2017
88 - seems to pass test suite down till 5.8.9, so make this the
89 minimum requirement in Makefile.PL.
90 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
91 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
92 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
93 fortified longjmp variants in some libcs.
94 - re-try JIT allocation without PROT_EXEC, to hopefully improve
95 portability (still doesn't seem to work around broken selinux
96 mmap everywhere).
97 - speling fixes (Xavier Guimard).
98
996.511 Sun Jun 26 23:44:50 CEST 2016
100 - make it compile with threaded perls again.
101 - simplify and speed up __DIE__ and __WARN__ handling.
102
1036.51 Sat Jun 25 20:57:20 CEST 2016
104 - 6.5 release didn't compile on most older perls due to
105 a logic error enabling experimental 5.24 code for all versions.
106 - since various broken or deficient patches float around
107 to work around the vtbl API breakage in perl, let's provide
108 our own workaround, which seems to be much less invasive
109 and more compatible than the approaches seen so far. YMMV.
110 - work around assertion failure in perl_destruct on 5.24
111 (analyzed by Dave Mitchell).
112
1136.5 Wed Jun 22 22:23:50 CEST 2016
114 - swap_sv swapping order was not symmetrical, causing
115 wrong swaps when swap_sv was used multiple times on the
116 same sv in the same thread.
117 - swap_sv calls can now be undone by calling it again
118 with the same variables.
119 - swap_sv calls will now be undone in async_pool threads.
120 - split Coro::Semaphore::up/adjust into separate xs functions
121 for better error reporting, at slight codesize increase.
122 - (libcoro) arm assembly support, please test and report.
123 - adjust to PL_savestack changes in perl 5.24 (adapted from
124 the debian patch, which unfortunately gets it wrong).
125
1266.49 Sat Oct 17 01:40:12 CEST 2015
127 - throwing an exception to a thread waiting in
128 Coro::Handle using Coro::EV did not stop the watchers,
129 causing the next call to fail (testcase by Martin Pritchard).
130 - bump minimum perl version to 5.10.
131
1326.48 Sun Oct 4 19:03:51 CEST 2015
133 - fix memory leak when Coro::Handle uses Coro::EV internally
134 (testcase by Sten Sten).
135 - update code to libev 4 API (internally, Coro still used the
136 version 3 API calls).
137 - remove unused hv_sig.
138
1396.47 Sat Jul 11 03:58:20 CEST 2015
140 - swap_svs - NVs can be in the SV head beginning with 5.20.
141
1426.46 Tue Jun 30 14:36:30 CEST 2015
143 - restore portability to perls with windows fork emulation
144 (patch by Petr Písař).
145
1466.45 Tue Jun 30 01:40:08 CEST 2015
147 - restore portability to perl 5.16 and below.
148
1496.44 Tue Jun 30 00:41:54 CEST 2015
150 - avoid segfaulting (or worse) when tracing a canceled thread.
151 - the Event module silently broke it's public hook API, causing
152 failures on perls compiled with -Duselongdouble. Requiring
153 the latest version of Event because I don't know which release
154 changed this (it's not mentioned in the ChangeLog).
155 - allow xs level enterleave hooks via CoroAPI.
156
1576.43 Thu Jun 4 15:38:14 CEST 2015
158 - use stability canary.
159 - port to stableperl-5.22.0-1.001.
160 - update libecb.
161
1626.42 Wed Feb 11 20:29:52 CET 2015
163 - Coro::SemaphoreSet->try did not actually work (analyzed by
164 SATO Kentaro).
165 - upgrade libecb to be C11 compliant.
166
1676.41 Sat Sep 6 22:08:46 CEST 2014
168 - restore portability to perl 5.8.x.
169 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
170 up some memory, but fixes "use feature" and similar modules
171 when used inside a Coro.
172 - allow zero as argument to Coro::Channel to mean the same thing
173 as no argument. this works with older versions as well,
174 but wasn't legal until now.
175 - slightly better c header file detection.
176
1776.39 Mon Jun 2 00:00:08 CEST 2014
178 - work around more incompatible changes in 5.20.
179
1806.38 Sun Jun 1 21:54:23 CEST 2014
181 - check that perl slots actually have enough space to hold
182 interpreter variables.
183 - untested port to perl 5.19 (64 bit tmps indices) (reported
184 by Andreas König).
185 - croak when cancel is called without a thread context.
186
1876.37 Tue Mar 4 13:27:33 CET 2014
188 - *sigh*, removed leftover debugging code from debugging a
189 perl bug, of all things.
190
1916.36 Tue Mar 4 07:11:59 CET 2014
192 - semaphores would not clear the destroy hook when interrupted
193 by ->throw, causing segfaults or worse.
194 - ->throw on a thread waiting for a semaphore did not acquire
195 the semaphore, but also didn't wake up other waiters,
196 possibly causing a deadlock.
197 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
198 to report a full stacktrace, which should help find out
199 where the actual call is.
200 - "atomically" destroy data in slf_destroy, because it is
201 the right thing to do, just in case.
202 - disable ecb.h libm dependency, to compile on ancient systems
203 or under adverse conditions.
204
2056.33 Mon Nov 18 11:26:27 CET 2013
206 - do not crash when freeing padlists with holes (in 5.18).
207 - tentative SVt_BIND 5.19 port/fix.
208
2096.32 Tue Nov 5 15:35:35 CET 2013
210 - use a new algorithm to derive padlists for perl 5.18. The old
211 one could lead to 0-pointer accesses inside perl (reported
212 by Darin McBride).
213
2146.31 Thu May 9 07:39:48 CEST 2013
215 - Coro::AIO requests would crash if the thread was ready'd
216 while the request was ongoing.
217
2186.29 Wed May 8 02:55:18 CEST 2013
219 - when an on_destroy handler destructs the coro currently being
220 destructed a perl scalar could be accessed after being freed,
221 likely causing a crash.
222
2236.28 Wed Mar 6 06:58:02 CET 2013
224 - clean remnants of existing __DIE__ and __WARN__ handlers so
225 they lose their magic and will not cause segfaults later
226 (testcase by Andrey Sagulin).
227 - improved Coro::State documentation a bit.
228 - Coro::Debug::command now flushes the output.
229 - add hack detection code for x32 abi, because the braindead slugs
230 who designed that made it look exactly like x86_64 without
231 providing proper compile time symbols to test for it. as a result,
232 this detection cannot work reliably.
233 - valgrind stack registering was broken.
234 - do not rely on Time::HiRes anymore in Coro::Debug.
235
2366.23 Fri Dec 7 23:36:37 CET 2012
237 - use experimental fiber implementation on native windows
238 perls.
239 - use sizeof (void *) as multiplication factor for stack sizes,
240 to accomodate the totally braindamaged microsoft 64 bit "os".
241 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
242 activeperl 5.16 crashes when PerlIO_define_layer is called due
243 to some bug in the perl dll, strawberry perl at least passes
244 the testsuite.
245 - implement Coro::Handle->peeraddr/host/port, for slightly
246 improved compatibility with LWP.
247 - implement 5.17 compatibility by almost blindly applying a
248 good-looking patch by Father Chrysostomos.
249 - move stack management functions into libcoro 3.
250 - libcoro version 3 "released".
10 - support magic values as timed_io_once args. 251 - support magic values as timed_io_once args.
11 - recommend AnyEvent 7+ or EV 4+, also require EV 252 - recommend AnyEvent 7+ or EV 4+, also require EV
12 version 4 or newer for Coro::EV. 253 version 4 or newer for Coro::EV.
