9
10 - minor code cleanups.
11
126.514 Thu Aug 31 18:25:31 CEST 2017
13 - safe_cancel no longer croaks when called on already-destroyed
14 thread, but instead "just works".
15
166.513 Sat Jul 15 01:18:51 CEST 2017
17 - experimental 5.22 comaptibility changes (PadlistNAMES).
18 - removed attributes example and made sure the other examples
19 still work.
20 - fix some statevar types for newer perls, should be of no consequence.
21
226.512 Fri Jul 14 05:03:17 CEST 2017
23 - seems to pass test suite down till 5.8.9, so make this the
24 minimum requirement in Makefile.PL.
25 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
26 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
27 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
28 fortified longjmp variants in some libcs.
29 - re-try JIT allocation without PROT_EXEC, to hopefully improve
30 portability (still doesn't seem to work around broken selinux
31 mmap everywhere).
32 - speling fixes (Xavier Guimard).
33
346.511 Sun Jun 26 23:44:50 CEST 2016
35 - make it compile with threaded perls again.
36 - simplify and speed up __DIE__ and __WARN__ handling.
37
386.51 Sat Jun 25 20:57:20 CEST 2016
39 - 6.5 release didn't compile on most older perls due to
40 a logic error enabling experimental 5.24 code for all versions.
41 - since various broken or deficient patches float around
42 to work around the vtbl API breakage in perl, let's provide
43 our own workaround, which seems to be much less invasive
44 and more compatible than the approaches seen so far. YMMV.
45 - work around assertion failure in perl_destruct on 5.24
46 (analyzed by Dave Mitchell).
47
486.5 Wed Jun 22 22:23:50 CEST 2016
49 - swap_sv swapping order was not symmetrical, causing
50 wrong swaps when swap_sv was used multiple times on the
51 same sv in the same thread.
52 - swap_sv calls can now be undone by calling it again
53 with the same variables.
54 - swap_sv calls will now be undone in async_pool threads.
55 - split Coro::Semaphore::up/adjust into separate xs functions
56 for better error reporting, at slight codesize increase.
57 - (libcoro) arm assembly support, please test and report.
58 - adjust to PL_savestack changes in perl 5.24 (adapted from
59 the debian patch, which unfortunately gets it wrong).
60
616.49 Sat Oct 17 01:40:12 CEST 2015
62 - throwing an exception to a thread waiting in
63 Coro::Handle using Coro::EV did not stop the watchers,
64 causing the next call to fail (testcase by Martin Pritchard).
65 - bump minimum perl version to 5.10.
66
676.48 Sun Oct 4 19:03:51 CEST 2015
68 - fix memory leak when Coro::Handle uses Coro::EV internally
69 (testcase by Sten Sten).
70 - update code to libev 4 API (internally, Coro still used the
71 version 3 API calls).
72 - remove unused hv_sig.
73
746.47 Sat Jul 11 03:58:20 CEST 2015
75 - swap_svs - NVs can be in the SV head beginning with 5.20.
76
776.46 Tue Jun 30 14:36:30 CEST 2015
78 - restore portability to perls with windows fork emulation
79 (patch by Petr Písař).
80
816.45 Tue Jun 30 01:40:08 CEST 2015
82 - restore portability to perl 5.16 and below.
83
846.44 Tue Jun 30 00:41:54 CEST 2015
85 - avoid segfaulting (or worse) when tracing a canceled thread.
86 - the Event module silently broke it's public hook API, causing
87 failures on perls compiled with -Duselongdouble. Requiring
88 the latest version of Event because I don't know which release
89 changed this (it's not mentioned in the ChangeLog).
90 - allow xs level enterleave hooks via CoroAPI.
91
926.43 Thu Jun 4 15:38:14 CEST 2015
93 - use stability canary.
94 - port to stableperl-5.22.0-1.001.
95 - update libecb.
96
976.42 Wed Feb 11 20:29:52 CET 2015
98 - Coro::SemaphoreSet->try did not actually work (analyzed by
99 SATO Kentaro).
100 - upgrade libecb to be C11 compliant.
101
1026.41 Sat Sep 6 22:08:46 CEST 2014
103 - restore portability to perl 5.8.x.
104 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
105 up some memory, but fixes "use feature" and similar modules
106 when used inside a Coro.
107 - allow zero as argument to Coro::Channel to mean the same thing
108 as no argument. this works with older versions as well,
109 but wasn't legal until now.
110 - slightly better c header file detection.
111
1126.39 Mon Jun 2 00:00:08 CEST 2014
113 - work around more incompatible changes in 5.20.
114
1156.38 Sun Jun 1 21:54:23 CEST 2014
116 - check that perl slots actually have enough space to hold
117 interpreter variables.
118 - untested port to perl 5.19 (64 bit tmps indices) (reported
119 by Andreas König).
120 - croak when cancel is called without a thread context.
121
1226.37 Tue Mar 4 13:27:33 CET 2014
123 - *sigh*, removed leftover debugging code from debugging a
124 perl bug, of all things.
125
1266.36 Tue Mar 4 07:11:59 CET 2014
127 - semaphores would not clear the destroy hook when interrupted
128 by ->throw, causing segfaults or worse.
129 - ->throw on a thread waiting for a semaphore did not acquire
130 the semaphore, but also didn't wake up other waiters,
131 possibly causing a deadlock.
132 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
133 to report a full stacktrace, which should help find out
134 where the actual call is.
135 - "atomically" destroy data in slf_destroy, because it is
136 the right thing to do, just in case.
137 - disable ecb.h libm dependency, to compile on ancient systems
138 or under adverse conditions.
139
1406.33 Mon Nov 18 11:26:27 CET 2013
141 - do not crash when freeing padlists with holes (in 5.18).
142 - tentative SVt_BIND 5.19 port/fix.
143
1446.32 Tue Nov 5 15:35:35 CET 2013
145 - use a new algorithm to derive padlists for perl 5.18. The old
146 one could lead to 0-pointer accesses inside perl (reported
147 by Darin McBride).
148
1496.31 Thu May 9 07:39:48 CEST 2013
150 - Coro::AIO requests would crash if the thread was ready'd
151 while the request was ongoing.
152
1536.29 Wed May 8 02:55:18 CEST 2013
154 - when an on_destroy handler destructs the coro currently being
155 destructed a perl scalar could be accessed after being freed,
156 likely causing a crash.
157
1586.28 Wed Mar 6 06:58:02 CET 2013
159 - clean remnants of existing __DIE__ and __WARN__ handlers so
160 they lose their magic and will not cause segfaults later
161 (testcase by Andrey Sagulin).
162 - improved Coro::State documentation a bit.
163 - Coro::Debug::command now flushes the output.
164 - add hack detection code for x32 abi, because the braindead slugs
165 who designed that made it look exactly like x86_64 without
166 providing proper compile time symbols to test for it. as a result,
167 this detection cannot work reliably.
168 - valgrind stack registering was broken.
169 - do not rely on Time::HiRes anymore in Coro::Debug.
170
1716.23 Fri Dec 7 23:36:37 CET 2012
172 - use experimental fiber implementation on native windows
173 perls.
174 - use sizeof (void *) as multiplication factor for stack sizes,
175 to accomodate the totally braindamaged microsoft 64 bit "os".
176 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
177 activeperl 5.16 crashes when PerlIO_define_layer is called due
178 to some bug in the perl dll, strawberry perl at least passes
179 the testsuite.
180 - implement Coro::Handle->peeraddr/host/port, for slightly
181 improved compatibility with LWP.
182 - implement 5.17 compatibility by almost blindly applying a
183 good-looking patch by Father Chrysostomos.
184 - move stack management functions into libcoro 3.
185 - libcoro version 3 "released".
186 - support magic values as timed_io_once args.
187 - recommend AnyEvent 7+ or EV 4+, also require EV
188 version 4 or newer for Coro::EV.
189
1906.10 Tue Oct 9 01:14:27 CEST 2012
191 - updated ecb.h, it had a typo that caused it to not compile on many
192 big endian systems (reported by many people).
193 - disable memory fences in ecb.h to improve portability.
194
1956.09 Sat Oct 6 23:25:02 CEST 2012
196 - Coro::EV I/O watchers were not interruptible by exceptions
197 (Coro::State::throw) (testcase by sten).
198 - ->throw now puts threads into the ready queue, as this seems to
199 be expected by existing code, and code that doesn't cope with spurious
200 wakeups needs fixing anyway.
201 - use fd -1 in mmap.
202 - cast I32 to int in error message printf.
203 - warn about broken so-called "hardened" kernels.
204
2056.08 Fri Apr 13 12:05:47 CEST 2012
206 - be more aggressive about exiting like perl does - formerly,
207 exiting from the non-main thread would not execute END blocks.
208
2096.07 Fri Nov 11 21:21:48 CET 2011
210 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
211 - update ecb.h.
212
2136.06 Mon Aug 8 23:59:48 CEST 2011
214 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
215 backend, which is an order of magnitude slower. unfortunately, cygwins
216 pthread implementation isn't very complete either, so allocate the stack
217 twice just to be sure.
218 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
219 in its ithreaded perl - best recompile cygwin and use the 'w'indows
220 backend for much better performance. also disable ithreads for
221 even better performance...).
222
2236.05 Thu Aug 4 21:36:36 CEST 2011
224 - blush, condvar values would not be propagated from send to recv anymore
225 (reported by Chip Salzenberg).
226 - use exponential increase for the readline buffer length in
227 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
