9 - simplify and speed up __DIE__ and __WARN__ handling.
10
116.51 Sat Jun 25 20:57:20 CEST 2016
12 - 6.5 release didn't compile on most older perls due to
13 a logic error enabling experimental 5.24 code for all versions.
14 - since various broken or deficient patches float around
15 to work around the vtbl API breakage in perl, let's provide
16 our own workaround, which seems to be much less invasive
17 and more compatible than the approaches seen so far. YMMV.
18 - work around assertion failure in perl_destruct on 5.24
19 (analyzed by Dave Mitchell).
20
216.5 Wed Jun 22 22:23:50 CEST 2016
22 - swap_sv swapping order was not symmetrical, causing
23 wrong swaps when swap_sv was used multiple times on the
24 same sv in the same thread.
25 - swap_sv calls can now be undone by calling it again
26 with the same variables.
27 - swap_sv calls will now be undone in async_pool threads.
28 - split Coro::Semaphore::up/adjust into separate xs functions
29 for better error reporting, at slight codesize increase.
30 - (libcoro) arm assembly support, please test and report.
31 - adjust to PL_savestack changes in perl 5.24 (adapted from
32 the debian patch, which unfortunately gets it wrong).
33
346.49 Sat Oct 17 01:40:12 CEST 2015
35 - throwing an exception to a thread waiting in
36 Coro::Handle using Coro::EV did not stop the watchers,
37 causing the next call to fail (testcase by Martin Pritchard).
38 - bump minimum perl version to 5.10.
39
406.48 Sun Oct 4 19:03:51 CEST 2015
41 - fix memory leak when Coro::Handle uses Coro::EV internally
42 (testcase by Sten Sten).
43 - update code to libev 4 API (internally, Coro still used the
44 version 3 API calls).
45 - remove unused hv_sig.
46
476.47 Sat Jul 11 03:58:20 CEST 2015
48 - swap_svs - NVs can be in the SV head beginning with 5.20.
49
506.46 Tue Jun 30 14:36:30 CEST 2015
51 - restore portability to perls with windows fork emulation
52 (patch by Petr Písař).
53
546.45 Tue Jun 30 01:40:08 CEST 2015
55 - restore portability to perl 5.16 and below.
56
576.44 Tue Jun 30 00:41:54 CEST 2015
58 - avoid segfaulting (or worse) when tracing a canceled thread.
59 - the Event module silently broke it's public hook API, causing
60 failures on perls compiled with -Duselongdouble. Requiring
61 the latest version of Event because I don't know which release
62 changed this (it's not mentioned in the ChangeLog).
63 - allow xs level enterleave hooks via CoroAPI.
64
656.43 Thu Jun 4 15:38:14 CEST 2015
66 - use stability canary.
67 - port to stableperl-5.22.0-1.001.
68 - update libecb.
69
706.42 Wed Feb 11 20:29:52 CET 2015
71 - Coro::SemaphoreSet->try did not actually work (analyzed by
72 SATO Kentaro).
73 - upgrade libecb to be C11 compliant.
74
756.41 Sat Sep 6 22:08:46 CEST 2014
76 - restore portability to perl 5.8.x.
77 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
78 up some memory, but fixes "use feature" and similar modules
79 when used inside a Coro.
80 - allow zero as argument to Coro::Channel to mean the same thing
81 as no argument. this works with older versions as well,
82 but wasn't legal until now.
83 - slightly better c header file detection.
84
856.39 Mon Jun 2 00:00:08 CEST 2014
86 - work around more incompatible changes in 5.20.
87
886.38 Sun Jun 1 21:54:23 CEST 2014
89 - check that perl slots actually have enough space to hold
90 interpreter variables.
91 - untested port to perl 5.19 (64 bit tmps indices) (reported
92 by Andreas König).
93 - croak when cancel is called without a thread context.
94
956.37 Tue Mar 4 13:27:33 CET 2014
96 - *sigh*, removed leftover debugging code from debugging a
97 perl bug, of all things.
98
996.36 Tue Mar 4 07:11:59 CET 2014
100 - semaphores would not clear the destroy hook when interrupted
101 by ->throw, causing segfaults or worse.
102 - ->throw on a thread waiting for a semaphore did not acquire
103 the semaphore, but also didn't wake up other waiters,
104 possibly causing a deadlock.
105 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
106 to report a full stacktrace, which should help find out
107 where the actual call is.
108 - "atomically" destroy data in slf_destroy, because it is
109 the right thing to do, just in case.
110 - disable ecb.h libm dependency, to compile on ancient systems
111 or under adverse conditions.
112
1136.33 Mon Nov 18 11:26:27 CET 2013
114 - do not crash when freeing padlists with holes (in 5.18).
115 - tentative SVt_BIND 5.19 port/fix.
116
1176.32 Tue Nov 5 15:35:35 CET 2013
118 - use a new algorithm to derive padlists for perl 5.18. The old
119 one could lead to 0-pointer accesses inside perl (reported
120 by Darin McBride).
121
1226.31 Thu May 9 07:39:48 CEST 2013
123 - Coro::AIO requests would crash if the thread was ready'd
124 while the request was ongoing.
125
1266.29 Wed May 8 02:55:18 CEST 2013
127 - when an on_destroy handler destructs the coro currently being
128 destructed a perl scalar could be accessed after being freed,
129 likely causing a crash.
130
1316.28 Wed Mar 6 06:58:02 CET 2013
132 - clean remnants of existing __DIE__ and __WARN__ handlers so
133 they lose their magic and will not cause segfaults later
134 (testcase by Andrey Sagulin).
135 - improved Coro::State documentation a bit.
136 - Coro::Debug::command now flushes the output.
137 - add hack detection code for x32 abi, because the braindead slugs
138 who designed that made it look exactly like x86_64 without
139 providing proper compile time symbols to test for it. as a result,
140 this detection cannot work reliably.
141 - valgrind stack registering was broken.
142 - do not rely on Time::HiRes anymore in Coro::Debug.
143
1446.23 Fri Dec 7 23:36:37 CET 2012
145 - use experimental fiber implementation on native windows
146 perls.
147 - use sizeof (void *) as multiplication factor for stack sizes,
148 to accomodate the totally braindamaged microsoft 64 bit "os".
149 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
150 activeperl 5.16 crashes when PerlIO_define_layer is called due
151 to some bug in the perl dll, strawberry perl at least passes
152 the testsuite.
153 - implement Coro::Handle->peeraddr/host/port, for slightly
154 improved compatibility with LWP.
155 - implement 5.17 compatibility by almost blindly applying a
156 good-looking patch by Father Chrysostomos.
157 - move stack management functions into libcoro 3.
158 - libcoro version 3 "released".
159 - support magic values as timed_io_once args.
160 - recommend AnyEvent 7+ or EV 4+, also require EV
161 version 4 or newer for Coro::EV.
162
1636.10 Tue Oct 9 01:14:27 CEST 2012
164 - updated ecb.h, it had a typo that caused it to not compile on many
165 big endian systems (reported by many people).
166 - disable memory fences in ecb.h to improve portability.
167
1686.09 Sat Oct 6 23:25:02 CEST 2012
169 - Coro::EV I/O watchers were not interruptible by exceptions
170 (Coro::State::throw) (testcase by sten).
171 - ->throw now puts threads into the ready queue, as this seems to
172 be expected by existing code, and code that doesn't cope with spurious
173 wakeups needs fixing anyway.
174 - use fd -1 in mmap.
175 - cast I32 to int in error message printf.
176 - warn about broken so-called "hardened" kernels.
177
1786.08 Fri Apr 13 12:05:47 CEST 2012
179 - be more aggressive about exiting like perl does - formerly,
180 exiting from the non-main thread would not execute END blocks.
181
1826.07 Fri Nov 11 21:21:48 CET 2011
183 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
184 - update ecb.h.
185
1866.06 Mon Aug 8 23:59:48 CEST 2011
187 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
188 backend, which is an order of magnitude slower. unfortunately, cygwins
189 pthread implementation isn't very complete either, so allocate the stack
190 twice just to be sure.
191 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
192 in its ithreaded perl - best recompile cygwin and use the 'w'indows
193 backend for much better performance. also disable ithreads for
194 even better performance...).
195
1966.05 Thu Aug 4 21:36:36 CEST 2011
197 - blush, condvar values would not be propagated from send to recv anymore
198 (reported by Chip Salzenberg).
199 - use exponential increase for the readline buffer length in
200 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
201
2026.04 Wed Aug 3 17:15:45 CEST 2011
203 - use even more efficient and more compatible condvars for
204 compatibility to AnyEvent 6.x :)
205 - more inconsequential ecb.h updates.
206
2076.03 Wed Aug 3 11:41:30 CEST 2011
208 - change how Coro patches AnyEvent condvars for compatibility to
209 AnyEvent 6.x.
7 - update ecb.h, to no longer include <pthread.h> in case WinNT.h 210 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
8 hasn't been included. 211 hasn't been included.
