10 - seems to pass test suite down till 5.8.9, so make this the
11 minimum requirement in Makefile.PL.
12 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
13 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
14 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
15 fortified longjmp variants in some libcs.
16 - re-try JIT allocation without PROT_EXEC, to hopefully improve
17 portability (still doesn't seem to work around broken selinux
18 mmap everywhere).
19 - speling fixes (Xavier Guimard).
20
216.511 Sun Jun 26 23:44:50 CEST 2016
22 - make it compile with threaded perls again.
23 - simplify and speed up __DIE__ and __WARN__ handling.
24
256.51 Sat Jun 25 20:57:20 CEST 2016
26 - 6.5 release didn't compile on most older perls due to
27 a logic error enabling experimental 5.24 code for all versions.
28 - since various broken or deficient patches float around
29 to work around the vtbl API breakage in perl, let's provide
30 our own workaround, which seems to be much less invasive
31 and more compatible than the approaches seen so far. YMMV.
32 - work around assertion failure in perl_destruct on 5.24
33 (analyzed by Dave Mitchell).
34
356.5 Wed Jun 22 22:23:50 CEST 2016
36 - swap_sv swapping order was not symmetrical, causing
37 wrong swaps when swap_sv was used multiple times on the
38 same sv in the same thread.
39 - swap_sv calls can now be undone by calling it again
40 with the same variables.
41 - swap_sv calls will now be undone in async_pool threads.
42 - split Coro::Semaphore::up/adjust into separate xs functions
43 for better error reporting, at slight codesize increase.
44 - (libcoro) arm assembly support, please test and report.
45 - adjust to PL_savestack changes in perl 5.24 (adapted from
46 the debian patch, which unfortunately gets it wrong).
47
486.49 Sat Oct 17 01:40:12 CEST 2015
49 - throwing an exception to a thread waiting in
50 Coro::Handle using Coro::EV did not stop the watchers,
51 causing the next call to fail (testcase by Martin Pritchard).
52 - bump minimum perl version to 5.10.
53
546.48 Sun Oct 4 19:03:51 CEST 2015
55 - fix memory leak when Coro::Handle uses Coro::EV internally
56 (testcase by Sten Sten).
57 - update code to libev 4 API (internally, Coro still used the
58 version 3 API calls).
59 - remove unused hv_sig.
60
616.47 Sat Jul 11 03:58:20 CEST 2015
62 - swap_svs - NVs can be in the SV head beginning with 5.20.
63
646.46 Tue Jun 30 14:36:30 CEST 2015
65 - restore portability to perls with windows fork emulation
66 (patch by Petr Písař).
67
686.45 Tue Jun 30 01:40:08 CEST 2015
69 - restore portability to perl 5.16 and below.
70
716.44 Tue Jun 30 00:41:54 CEST 2015
72 - avoid segfaulting (or worse) when tracing a canceled thread.
73 - the Event module silently broke it's public hook API, causing
74 failures on perls compiled with -Duselongdouble. Requiring
75 the latest version of Event because I don't know which release
76 changed this (it's not mentioned in the ChangeLog).
77 - allow xs level enterleave hooks via CoroAPI.
78
796.43 Thu Jun 4 15:38:14 CEST 2015
80 - use stability canary.
81 - port to stableperl-5.22.0-1.001.
82 - update libecb.
83
846.42 Wed Feb 11 20:29:52 CET 2015
85 - Coro::SemaphoreSet->try did not actually work (analyzed by
86 SATO Kentaro).
87 - upgrade libecb to be C11 compliant.
88
896.41 Sat Sep 6 22:08:46 CEST 2014
90 - restore portability to perl 5.8.x.
91 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
92 up some memory, but fixes "use feature" and similar modules
93 when used inside a Coro.
94 - allow zero as argument to Coro::Channel to mean the same thing
95 as no argument. this works with older versions as well,
96 but wasn't legal until now.
97 - slightly better c header file detection.
98
996.39 Mon Jun 2 00:00:08 CEST 2014
100 - work around more incompatible changes in 5.20.
101
1026.38 Sun Jun 1 21:54:23 CEST 2014
103 - check that perl slots actually have enough space to hold
104 interpreter variables.
105 - untested port to perl 5.19 (64 bit tmps indices) (reported
106 by Andreas König).
107 - croak when cancel is called without a thread context.
108
1096.37 Tue Mar 4 13:27:33 CET 2014
110 - *sigh*, removed leftover debugging code from debugging a
111 perl bug, of all things.
112
1136.36 Tue Mar 4 07:11:59 CET 2014
114 - semaphores would not clear the destroy hook when interrupted
115 by ->throw, causing segfaults or worse.
116 - ->throw on a thread waiting for a semaphore did not acquire
117 the semaphore, but also didn't wake up other waiters,
118 possibly causing a deadlock.
119 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
120 to report a full stacktrace, which should help find out
121 where the actual call is.
122 - "atomically" destroy data in slf_destroy, because it is
123 the right thing to do, just in case.
124 - disable ecb.h libm dependency, to compile on ancient systems
125 or under adverse conditions.
126
1276.33 Mon Nov 18 11:26:27 CET 2013
128 - do not crash when freeing padlists with holes (in 5.18).
129 - tentative SVt_BIND 5.19 port/fix.
130
1316.32 Tue Nov 5 15:35:35 CET 2013
132 - use a new algorithm to derive padlists for perl 5.18. The old
133 one could lead to 0-pointer accesses inside perl (reported
134 by Darin McBride).
135
1366.31 Thu May 9 07:39:48 CEST 2013
137 - Coro::AIO requests would crash if the thread was ready'd
138 while the request was ongoing.
139
1406.29 Wed May 8 02:55:18 CEST 2013
141 - when an on_destroy handler destructs the coro currently being
142 destructed a perl scalar could be accessed after being freed,
143 likely causing a crash.
144
1456.28 Wed Mar 6 06:58:02 CET 2013
146 - clean remnants of existing __DIE__ and __WARN__ handlers so
147 they lose their magic and will not cause segfaults later
148 (testcase by Andrey Sagulin).
149 - improved Coro::State documentation a bit.
150 - Coro::Debug::command now flushes the output.
151 - add hack detection code for x32 abi, because the braindead slugs
152 who designed that made it look exactly like x86_64 without
153 providing proper compile time symbols to test for it. as a result,
154 this detection cannot work reliably.
155 - valgrind stack registering was broken.
156 - do not rely on Time::HiRes anymore in Coro::Debug.
157
1586.23 Fri Dec 7 23:36:37 CET 2012
159 - use experimental fiber implementation on native windows
160 perls.
161 - use sizeof (void *) as multiplication factor for stack sizes,
162 to accomodate the totally braindamaged microsoft 64 bit "os".
163 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
164 activeperl 5.16 crashes when PerlIO_define_layer is called due
165 to some bug in the perl dll, strawberry perl at least passes
166 the testsuite.
167 - implement Coro::Handle->peeraddr/host/port, for slightly
168 improved compatibility with LWP.
169 - implement 5.17 compatibility by almost blindly applying a
170 good-looking patch by Father Chrysostomos.
171 - move stack management functions into libcoro 3.
172 - libcoro version 3 "released".
173 - support magic values as timed_io_once args.
174 - recommend AnyEvent 7+ or EV 4+, also require EV
175 version 4 or newer for Coro::EV.
176
1776.10 Tue Oct 9 01:14:27 CEST 2012
178 - updated ecb.h, it had a typo that caused it to not compile on many
179 big endian systems (reported by many people).
180 - disable memory fences in ecb.h to improve portability.
181
1826.09 Sat Oct 6 23:25:02 CEST 2012
183 - Coro::EV I/O watchers were not interruptible by exceptions
184 (Coro::State::throw) (testcase by sten).
185 - ->throw now puts threads into the ready queue, as this seems to
186 be expected by existing code, and code that doesn't cope with spurious
187 wakeups needs fixing anyway.
188 - use fd -1 in mmap.
189 - cast I32 to int in error message printf.
190 - warn about broken so-called "hardened" kernels.
191
1926.08 Fri Apr 13 12:05:47 CEST 2012
193 - be more aggressive about exiting like perl does - formerly,
194 exiting from the non-main thread would not execute END blocks.
195
1966.07 Fri Nov 11 21:21:48 CET 2011
197 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
198 - update ecb.h.
199
2006.06 Mon Aug 8 23:59:48 CEST 2011
201 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
202 backend, which is an order of magnitude slower. unfortunately, cygwins
203 pthread implementation isn't very complete either, so allocate the stack
204 twice just to be sure.
205 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
206 in its ithreaded perl - best recompile cygwin and use the 'w'indows
207 backend for much better performance. also disable ithreads for
208 even better performance...).
209
2106.05 Thu Aug 4 21:36:36 CEST 2011
211 - blush, condvar values would not be propagated from send to recv anymore
212 (reported by Chip Salzenberg).
213 - use exponential increase for the readline buffer length in
214 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
215
2166.04 Wed Aug 3 17:15:45 CEST 2011
217 - use even more efficient and more compatible condvars for
218 compatibility to AnyEvent 6.x :)
219 - more inconsequential ecb.h updates.
220
2216.03 Wed Aug 3 11:41:30 CEST 2011
222 - change how Coro patches AnyEvent condvars for compatibility to
223 AnyEvent 6.x.
224 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
225 hasn't been included.
