|
|
9 | - work around assertion failure in perl_destruct on 5.24 |
|
|
10 | (analyzed by Dave Mitchell). |
|
|
11 | |
|
|
12 | 6.5 Wed Jun 22 22:23:50 CEST 2016 |
|
|
13 | - swap_sv swapping order was not symmetrical, causing |
|
|
14 | wrong swaps when swap_sv was used multiple times on the |
|
|
15 | same sv in the same thread. |
|
|
16 | - swap_sv calls can now be undone by calling it again |
|
|
17 | with the same variables. |
|
|
18 | - swap_sv calls will now be undone in async_pool threads. |
|
|
19 | - split Coro::Semaphore::up/adjust into separate xs functions |
|
|
20 | for better error reporting, at slight codesize increase. |
|
|
21 | - (libcoro) arm assembly support, please test and report. |
|
|
22 | - adjust to PL_savestack changes in perl 5.24 (adapted from |
|
|
23 | the debian patch, which unfortunately gets it wrong). |
|
|
24 | |
|
|
25 | 6.49 Sat Oct 17 01:40:12 CEST 2015 |
|
|
26 | - throwing an exception to a thread waiting in |
|
|
27 | Coro::Handle using Coro::EV did not stop the watchers, |
|
|
28 | causing the next call to fail (testcase by Martin Pritchard). |
|
|
29 | - bump minimum perl version to 5.10. |
|
|
30 | |
|
|
31 | 6.48 Sun Oct 4 19:03:51 CEST 2015 |
|
|
32 | - fix memory leak when Coro::Handle uses Coro::EV internally |
|
|
33 | (testcase by Sten Sten). |
|
|
34 | - update code to libev 4 API (internally, Coro still used the |
|
|
35 | version 3 API calls). |
|
|
36 | - remove unused hv_sig. |
|
|
37 | |
|
|
38 | 6.47 Sat Jul 11 03:58:20 CEST 2015 |
|
|
39 | - swap_svs - NVs can be in the SV head beginning with 5.20. |
|
|
40 | |
|
|
41 | 6.46 Tue Jun 30 14:36:30 CEST 2015 |
|
|
42 | - restore portability to perls with windows fork emulation |
|
|
43 | (patch by Petr Písař). |
|
|
44 | |
|
|
45 | 6.45 Tue Jun 30 01:40:08 CEST 2015 |
|
|
46 | - restore portability to perl 5.16 and below. |
|
|
47 | |
|
|
48 | 6.44 Tue Jun 30 00:41:54 CEST 2015 |
|
|
49 | - avoid segfaulting (or worse) when tracing a canceled thread. |
|
|
50 | - the Event module silently broke it's public hook API, causing |
|
|
51 | failures on perls compiled with -Duselongdouble. Requiring |
|
|
52 | the latest version of Event because I don't know which release |
|
|
53 | changed this (it's not mentioned in the ChangeLog). |
|
|
54 | - allow xs level enterleave hooks via CoroAPI. |
|
|
55 | |
|
|
56 | 6.43 Thu Jun 4 15:38:14 CEST 2015 |
|
|
57 | - use stability canary. |
|
|
58 | - port to stableperl-5.22.0-1.001. |
|
|
59 | - update libecb. |
|
|
60 | |
|
|
61 | 6.42 Wed Feb 11 20:29:52 CET 2015 |
|
|
62 | - Coro::SemaphoreSet->try did not actually work (analyzed by |
|
|
63 | SATO Kentaro). |
|
|
64 | - upgrade libecb to be C11 compliant. |
|
|
65 | |
|
|
66 | 6.41 Sat Sep 6 22:08:46 CEST 2014 |
|
|
67 | - restore portability to perl 5.8.x. |
|
|
68 | - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes |
|
|
69 | up some memory, but fixes "use feature" and similar modules |
|
|
70 | when used inside a Coro. |
|
|
71 | - allow zero as argument to Coro::Channel to mean the same thing |
|
|
72 | as no argument. this works with older versions as well, |
|
|
73 | but wasn't legal until now. |
|
|
74 | - slightly better c header file detection. |
|
|
75 | |
|
|
76 | 6.39 Mon Jun 2 00:00:08 CEST 2014 |
|
|
77 | - work around more incompatible changes in 5.20. |
|
|
78 | |
|
|
79 | 6.38 Sun Jun 1 21:54:23 CEST 2014 |
|
|
80 | - check that perl slots actually have enough space to hold |
|
|
81 | interpreter variables. |
|
|
82 | - untested port to perl 5.19 (64 bit tmps indices) (reported |
|
|
83 | by Andreas König). |
|
|
84 | - croak when cancel is called without a thread context. |
|
|
85 | |
|
|
86 | 6.37 Tue Mar 4 13:27:33 CET 2014 |
|
|
87 | - *sigh*, removed leftover debugging code from debugging a |
|
|
88 | perl bug, of all things. |
|
|
89 | |
|
|
90 | 6.36 Tue Mar 4 07:11:59 CET 2014 |
|
|
91 | - semaphores would not clear the destroy hook when interrupted |
|
|
92 | by ->throw, causing segfaults or worse. |
|
|
93 | - ->throw on a thread waiting for a semaphore did not acquire |
|
|
94 | the semaphore, but also didn't wake up other waiters, |
|
|
95 | possibly causing a deadlock. |
|
|
96 | - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess |
|
|
97 | to report a full stacktrace, which should help find out |
|
|
98 | where the actual call is. |
|
|
99 | - "atomically" destroy data in slf_destroy, because it is |
|
|
100 | the right thing to do, just in case. |
|
|
101 | - disable ecb.h libm dependency, to compile on ancient systems |
|
|
102 | or under adverse conditions. |
|
|
103 | |
|
|
104 | 6.33 Mon Nov 18 11:26:27 CET 2013 |
|
|
105 | - do not crash when freeing padlists with holes (in 5.18). |
|
|
106 | - tentative SVt_BIND 5.19 port/fix. |
|
|
107 | |
|
|
108 | 6.32 Tue Nov 5 15:35:35 CET 2013 |
|
|
109 | - use a new algorithm to derive padlists for perl 5.18. The old |
|
|
110 | one could lead to 0-pointer accesses inside perl (reported |
|
|
111 | by Darin McBride). |
|
|
112 | |
|
|
113 | 6.31 Thu May 9 07:39:48 CEST 2013 |
|
|
114 | - Coro::AIO requests would crash if the thread was ready'd |
|
|
115 | while the request was ongoing. |
|
|
116 | |
|
|
117 | 6.29 Wed May 8 02:55:18 CEST 2013 |
|
|
118 | - when an on_destroy handler destructs the coro currently being |
|
|
119 | destructed a perl scalar could be accessed after being freed, |
|
|
120 | likely causing a crash. |
|
|
121 | |
|
|
122 | 6.28 Wed Mar 6 06:58:02 CET 2013 |
|
|
123 | - clean remnants of existing __DIE__ and __WARN__ handlers so |
|
|
124 | they lose their magic and will not cause segfaults later |
|
|
125 | (testcase by Andrey Sagulin). |
|
|
126 | - improved Coro::State documentation a bit. |
|
|
127 | - Coro::Debug::command now flushes the output. |
|
|
128 | - add hack detection code for x32 abi, because the braindead slugs |
|
|
129 | who designed that made it look exactly like x86_64 without |
|
|
130 | providing proper compile time symbols to test for it. as a result, |
|
|
131 | this detection cannot work reliably. |
|
|
132 | - valgrind stack registering was broken. |
|
|
133 | - do not rely on Time::HiRes anymore in Coro::Debug. |
|
|
134 | |
|
|
135 | 6.23 Fri Dec 7 23:36:37 CET 2012 |
|
|
136 | - use experimental fiber implementation on native windows |
|
|
137 | perls. |
|
|
138 | - use sizeof (void *) as multiplication factor for stack sizes, |
|
|
139 | to accomodate the totally braindamaged microsoft 64 bit "os". |
|
|
140 | - changed verifier host from win2k-ap510-32 to win7-sp516-32/64. |
|
|
141 | activeperl 5.16 crashes when PerlIO_define_layer is called due |
|
|
142 | to some bug in the perl dll, strawberry perl at least passes |
|
|
143 | the testsuite. |
|
|
144 | - implement Coro::Handle->peeraddr/host/port, for slightly |
|
|
145 | improved compatibility with LWP. |
|
|
146 | - implement 5.17 compatibility by almost blindly applying a |
|
|
147 | good-looking patch by Father Chrysostomos. |
|
|
148 | - move stack management functions into libcoro 3. |
|
|
149 | - libcoro version 3 "released". |
|
|
150 | - support magic values as timed_io_once args. |
|
|
151 | - recommend AnyEvent 7+ or EV 4+, also require EV |
|
|
152 | version 4 or newer for Coro::EV. |
|
|
153 | |
|
|
154 | 6.10 Tue Oct 9 01:14:27 CEST 2012 |
|
|
155 | - updated ecb.h, it had a typo that caused it to not compile on many |
|
|
156 | big endian systems (reported by many people). |
|
|
157 | - disable memory fences in ecb.h to improve portability. |
|
|
158 | |
|
|
159 | 6.09 Sat Oct 6 23:25:02 CEST 2012 |
|
|
160 | - Coro::EV I/O watchers were not interruptible by exceptions |
|
|
161 | (Coro::State::throw) (testcase by sten). |
|
|
162 | - ->throw now puts threads into the ready queue, as this seems to |
|
|
163 | be expected by existing code, and code that doesn't cope with spurious |
|
|
164 | wakeups needs fixing anyway. |
|
|
165 | - use fd -1 in mmap. |
|
|
166 | - cast I32 to int in error message printf. |
|
|
167 | - warn about broken so-called "hardened" kernels. |
|
|
168 | |
|
|
169 | 6.08 Fri Apr 13 12:05:47 CEST 2012 |
|
|
170 | - be more aggressive about exiting like perl does - formerly, |
|
|
171 | exiting from the non-main thread would not execute END blocks. |
|
|
172 | |
|
|
173 | 6.07 Fri Nov 11 21:21:48 CET 2011 |
|
|
174 | - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV). |
|
|
175 | - update ecb.h. |
|
|
176 | |
|
|
177 | 6.06 Mon Aug 8 23:59:48 CEST 2011 |
|
|
178 | - cygwin unfortunately patches the stack at runtime, so we use the pthreads |
|
|
179 | backend, which is an order of magnitude slower. unfortunately, cygwins |
|
|
180 | pthread implementation isn't very complete either, so allocate the stack |
|
|
181 | twice just to be sure. |
|
|
182 | (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS, |
|
|
183 | in its ithreaded perl - best recompile cygwin and use the 'w'indows |
|
|
184 | backend for much better performance. also disable ithreads for |
|
|
185 | even better performance...). |
|
|
186 | |
|
|
187 | 6.05 Thu Aug 4 21:36:36 CEST 2011 |
|
|
188 | - blush, condvar values would not be propagated from send to recv anymore |
|
|
189 | (reported by Chip Salzenberg). |
|
|
190 | - use exponential increase for the readline buffer length in |
|
|
191 | Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes. |
|
|
192 | |
|
|
193 | 6.04 Wed Aug 3 17:15:45 CEST 2011 |
|
|
194 | - use even more efficient and more compatible condvars for |
|
|
195 | compatibility to AnyEvent 6.x :) |
|
|
196 | - more inconsequential ecb.h updates. |
| 6 | |
