76.04 116.55 Fri Jul 19 17:28:09 CEST 2019
12 - Coro::RWLock woke up only one reader instead of all after a wrlock
13 (analyzed and patch by Maxim Skorobogatov).
14 - slightly improved documentation of Coro::RWLock and RWLock testcase.
15 - quickly (re)-ported to minix 3.3 before minix crashed again.
16
176.54 Sun Dec 16 11:06:07 CET 2018
18 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
19
206.53 Sun Dec 16 10:33:15 CET 2018
21 - the autogenerated prototypes of Coro::AIO now add ";" at the end
22 to avoid generating named unary operators and messing up parsing
23 (mostly affects aio_mlockall 4 | 8 which was parsed as
24 (aio_mlockall 4) | 8).
25 - do not use a prototype for select in Coro::Select, as CORE::select also
26 doesn't have one.
27
286.52 Tue Aug 14 18:49:43 CEST 2018
29 - libcoro update: allow sharing of coro threads using the pthreads
30 backend among different pthreads, as is required by Coro::Multicore.
31 - always allow ->call and ->eval when the coro is the current coroutine. this
32 makes it possible, among other things, to call these on $Coro::main.
33 - minor code cleanups.
34
356.514 Thu Aug 31 18:25:31 CEST 2017
36 - safe_cancel no longer croaks when called on already-destroyed
37 thread, but instead "just works".
38
396.513 Sat Jul 15 01:18:51 CEST 2017
40 - experimental 5.22 comaptibility changes (PadlistNAMES).
41 - removed attributes example and made sure the other examples
42 still work.
43 - fix some statevar types for newer perls, should be of no consequence.
44
456.512 Fri Jul 14 05:03:17 CEST 2017
46 - seems to pass test suite down till 5.8.9, so make this the
47 minimum requirement in Makefile.PL.
48 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
49 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
50 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
51 fortified longjmp variants in some libcs.
52 - re-try JIT allocation without PROT_EXEC, to hopefully improve
53 portability (still doesn't seem to work around broken selinux
54 mmap everywhere).
55 - speling fixes (Xavier Guimard).
56
576.511 Sun Jun 26 23:44:50 CEST 2016
58 - make it compile with threaded perls again.
59 - simplify and speed up __DIE__ and __WARN__ handling.
60
616.51 Sat Jun 25 20:57:20 CEST 2016
62 - 6.5 release didn't compile on most older perls due to
63 a logic error enabling experimental 5.24 code for all versions.
64 - since various broken or deficient patches float around
65 to work around the vtbl API breakage in perl, let's provide
66 our own workaround, which seems to be much less invasive
67 and more compatible than the approaches seen so far. YMMV.
68 - work around assertion failure in perl_destruct on 5.24
69 (analyzed by Dave Mitchell).
70
716.5 Wed Jun 22 22:23:50 CEST 2016
72 - swap_sv swapping order was not symmetrical, causing
73 wrong swaps when swap_sv was used multiple times on the
74 same sv in the same thread.
75 - swap_sv calls can now be undone by calling it again
76 with the same variables.
77 - swap_sv calls will now be undone in async_pool threads.
78 - split Coro::Semaphore::up/adjust into separate xs functions
79 for better error reporting, at slight codesize increase.
80 - (libcoro) arm assembly support, please test and report.
81 - adjust to PL_savestack changes in perl 5.24 (adapted from
82 the debian patch, which unfortunately gets it wrong).
83
846.49 Sat Oct 17 01:40:12 CEST 2015
85 - throwing an exception to a thread waiting in
86 Coro::Handle using Coro::EV did not stop the watchers,
87 causing the next call to fail (testcase by Martin Pritchard).
88 - bump minimum perl version to 5.10.
89
906.48 Sun Oct 4 19:03:51 CEST 2015
91 - fix memory leak when Coro::Handle uses Coro::EV internally
92 (testcase by Sten Sten).
93 - update code to libev 4 API (internally, Coro still used the
94 version 3 API calls).
95 - remove unused hv_sig.
96
976.47 Sat Jul 11 03:58:20 CEST 2015
98 - swap_svs - NVs can be in the SV head beginning with 5.20.
99
1006.46 Tue Jun 30 14:36:30 CEST 2015
101 - restore portability to perls with windows fork emulation
102 (patch by Petr Písař).
103
1046.45 Tue Jun 30 01:40:08 CEST 2015
105 - restore portability to perl 5.16 and below.
106
1076.44 Tue Jun 30 00:41:54 CEST 2015
108 - avoid segfaulting (or worse) when tracing a canceled thread.
109 - the Event module silently broke it's public hook API, causing
110 failures on perls compiled with -Duselongdouble. Requiring
111 the latest version of Event because I don't know which release
112 changed this (it's not mentioned in the ChangeLog).
113 - allow xs level enterleave hooks via CoroAPI.
114
1156.43 Thu Jun 4 15:38:14 CEST 2015
116 - use stability canary.
117 - port to stableperl-5.22.0-1.001.
118 - update libecb.
119
1206.42 Wed Feb 11 20:29:52 CET 2015
121 - Coro::SemaphoreSet->try did not actually work (analyzed by
122 SATO Kentaro).
123 - upgrade libecb to be C11 compliant.
124
1256.41 Sat Sep 6 22:08:46 CEST 2014
126 - restore portability to perl 5.8.x.
127 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
128 up some memory, but fixes "use feature" and similar modules
129 when used inside a Coro.
130 - allow zero as argument to Coro::Channel to mean the same thing
131 as no argument. this works with older versions as well,
132 but wasn't legal until now.
133 - slightly better c header file detection.
134
1356.39 Mon Jun 2 00:00:08 CEST 2014
136 - work around more incompatible changes in 5.20.
137
1386.38 Sun Jun 1 21:54:23 CEST 2014
139 - check that perl slots actually have enough space to hold
140 interpreter variables.
141 - untested port to perl 5.19 (64 bit tmps indices) (reported
142 by Andreas König).
143 - croak when cancel is called without a thread context.
144
1456.37 Tue Mar 4 13:27:33 CET 2014
146 - *sigh*, removed leftover debugging code from debugging a
147 perl bug, of all things.
148
1496.36 Tue Mar 4 07:11:59 CET 2014
150 - semaphores would not clear the destroy hook when interrupted
151 by ->throw, causing segfaults or worse.
152 - ->throw on a thread waiting for a semaphore did not acquire
153 the semaphore, but also didn't wake up other waiters,
154 possibly causing a deadlock.
155 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
156 to report a full stacktrace, which should help find out
157 where the actual call is.
158 - "atomically" destroy data in slf_destroy, because it is
159 the right thing to do, just in case.
160 - disable ecb.h libm dependency, to compile on ancient systems
161 or under adverse conditions.
162
1636.33 Mon Nov 18 11:26:27 CET 2013
164 - do not crash when freeing padlists with holes (in 5.18).
165 - tentative SVt_BIND 5.19 port/fix.
166
1676.32 Tue Nov 5 15:35:35 CET 2013
168 - use a new algorithm to derive padlists for perl 5.18. The old
169 one could lead to 0-pointer accesses inside perl (reported
170 by Darin McBride).
171
1726.31 Thu May 9 07:39:48 CEST 2013
173 - Coro::AIO requests would crash if the thread was ready'd
174 while the request was ongoing.
175
1766.29 Wed May 8 02:55:18 CEST 2013
177 - when an on_destroy handler destructs the coro currently being
178 destructed a perl scalar could be accessed after being freed,
179 likely causing a crash.
180
1816.28 Wed Mar 6 06:58:02 CET 2013
182 - clean remnants of existing __DIE__ and __WARN__ handlers so
183 they lose their magic and will not cause segfaults later
184 (testcase by Andrey Sagulin).
185 - improved Coro::State documentation a bit.
186 - Coro::Debug::command now flushes the output.
187 - add hack detection code for x32 abi, because the braindead slugs
188 who designed that made it look exactly like x86_64 without
189 providing proper compile time symbols to test for it. as a result,
190 this detection cannot work reliably.
191 - valgrind stack registering was broken.
192 - do not rely on Time::HiRes anymore in Coro::Debug.
193
1946.23 Fri Dec 7 23:36:37 CET 2012
195 - use experimental fiber implementation on native windows
196 perls.
197 - use sizeof (void *) as multiplication factor for stack sizes,
198 to accomodate the totally braindamaged microsoft 64 bit "os".
199 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
200 activeperl 5.16 crashes when PerlIO_define_layer is called due
201 to some bug in the perl dll, strawberry perl at least passes
202 the testsuite.
203 - implement Coro::Handle->peeraddr/host/port, for slightly
204 improved compatibility with LWP.
205 - implement 5.17 compatibility by almost blindly applying a
206 good-looking patch by Father Chrysostomos.
207 - move stack management functions into libcoro 3.
208 - libcoro version 3 "released".
209 - support magic values as timed_io_once args.
210 - recommend AnyEvent 7+ or EV 4+, also require EV
211 version 4 or newer for Coro::EV.
212
2136.10 Tue Oct 9 01:14:27 CEST 2012
214 - updated ecb.h, it had a typo that caused it to not compile on many
215 big endian systems (reported by many people).
216 - disable memory fences in ecb.h to improve portability.
217
2186.09 Sat Oct 6 23:25:02 CEST 2012
219 - Coro::EV I/O watchers were not interruptible by exceptions
220 (Coro::State::throw) (testcase by sten).
221 - ->throw now puts threads into the ready queue, as this seems to
222 be expected by existing code, and code that doesn't cope with spurious
223 wakeups needs fixing anyway.
224 - use fd -1 in mmap.
225 - cast I32 to int in error message printf.
226 - warn about broken so-called "hardened" kernels.
227
2286.08 Fri Apr 13 12:05:47 CEST 2012
229 - be more aggressive about exiting like perl does - formerly,
230 exiting from the non-main thread would not execute END blocks.
231
2326.07 Fri Nov 11 21:21:48 CET 2011
233 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
234 - update ecb.h.
235
2366.06 Mon Aug 8 23:59:48 CEST 2011
237 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
238 backend, which is an order of magnitude slower. unfortunately, cygwins
239 pthread implementation isn't very complete either, so allocate the stack
240 twice just to be sure.
241 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
242 in its ithreaded perl - best recompile cygwin and use the 'w'indows
243 backend for much better performance. also disable ithreads for
244 even better performance...).
245
2466.05 Thu Aug 4 21:36:36 CEST 2011
247 - blush, condvar values would not be propagated from send to recv anymore
248 (reported by Chip Salzenberg).
249 - use exponential increase for the readline buffer length in
250 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
251
2526.04 Wed Aug 3 17:15:45 CEST 2011
8 - use even more effciient and more compatible condvars for 253 - use even more efficient and more compatible condvars for
