|
9 | - re-try JIT allocation without PROT_EXEC, to hopefully improve |
|
|
10 | portability. |
|
|
11 | |
|
|
12 | 6.511 Sun Jun 26 23:44:50 CEST 2016 |
|
|
13 | - make it compile with threaded perls again. |
|
|
14 | - simplify and speed up __DIE__ and __WARN__ handling. |
|
|
15 | |
|
|
16 | 6.51 Sat Jun 25 20:57:20 CEST 2016 |
|
|
17 | - 6.5 release didn't compile on most older perls due to |
|
|
18 | a logic error enabling experimental 5.24 code for all versions. |
|
|
19 | - since various broken or deficient patches float around |
|
|
20 | to work around the vtbl API breakage in perl, let's provide |
|
|
21 | our own workaround, which seems to be much less invasive |
|
|
22 | and more compatible than the approaches seen so far. YMMV. |
|
|
23 | - work around assertion failure in perl_destruct on 5.24 |
|
|
24 | (analyzed by Dave Mitchell). |
|
|
25 | |
|
|
26 | 6.5 Wed Jun 22 22:23:50 CEST 2016 |
|
|
27 | - swap_sv swapping order was not symmetrical, causing |
|
|
28 | wrong swaps when swap_sv was used multiple times on the |
|
|
29 | same sv in the same thread. |
|
|
30 | - swap_sv calls can now be undone by calling it again |
|
|
31 | with the same variables. |
|
|
32 | - swap_sv calls will now be undone in async_pool threads. |
|
|
33 | - split Coro::Semaphore::up/adjust into separate xs functions |
|
|
34 | for better error reporting, at slight codesize increase. |
|
|
35 | - (libcoro) arm assembly support, please test and report. |
|
|
36 | - adjust to PL_savestack changes in perl 5.24 (adapted from |
|
|
37 | the debian patch, which unfortunately gets it wrong). |
|
|
38 | |
|
|
39 | 6.49 Sat Oct 17 01:40:12 CEST 2015 |
|
|
40 | - throwing an exception to a thread waiting in |
|
|
41 | Coro::Handle using Coro::EV did not stop the watchers, |
|
|
42 | causing the next call to fail (testcase by Martin Pritchard). |
|
|
43 | - bump minimum perl version to 5.10. |
|
|
44 | |
|
|
45 | 6.48 Sun Oct 4 19:03:51 CEST 2015 |
|
|
46 | - fix memory leak when Coro::Handle uses Coro::EV internally |
|
|
47 | (testcase by Sten Sten). |
|
|
48 | - update code to libev 4 API (internally, Coro still used the |
|
|
49 | version 3 API calls). |
|
|
50 | - remove unused hv_sig. |
|
|
51 | |
|
|
52 | 6.47 Sat Jul 11 03:58:20 CEST 2015 |
|
|
53 | - swap_svs - NVs can be in the SV head beginning with 5.20. |
|
|
54 | |
|
|
55 | 6.46 Tue Jun 30 14:36:30 CEST 2015 |
|
|
56 | - restore portability to perls with windows fork emulation |
|
|
57 | (patch by Petr Písař). |
|
|
58 | |
|
|
59 | 6.45 Tue Jun 30 01:40:08 CEST 2015 |
|
|
60 | - restore portability to perl 5.16 and below. |
|
|
61 | |
|
|
62 | 6.44 Tue Jun 30 00:41:54 CEST 2015 |
|
|
63 | - avoid segfaulting (or worse) when tracing a canceled thread. |
|
|
64 | - the Event module silently broke it's public hook API, causing |
|
|
65 | failures on perls compiled with -Duselongdouble. Requiring |
|
|
66 | the latest version of Event because I don't know which release |
|
|
67 | changed this (it's not mentioned in the ChangeLog). |
|
|
68 | - allow xs level enterleave hooks via CoroAPI. |
|
|
69 | |
|
|
70 | 6.43 Thu Jun 4 15:38:14 CEST 2015 |
|
|
71 | - use stability canary. |
|
|
72 | - port to stableperl-5.22.0-1.001. |
|
|
73 | - update libecb. |
|
|
74 | |
|
|
75 | 6.42 Wed Feb 11 20:29:52 CET 2015 |
|
|
76 | - Coro::SemaphoreSet->try did not actually work (analyzed by |
|
|
77 | SATO Kentaro). |
|
|
78 | - upgrade libecb to be C11 compliant. |
|
|
79 | |
|
|
80 | 6.41 Sat Sep 6 22:08:46 CEST 2014 |
|
|
81 | - restore portability to perl 5.8.x. |
|
|
82 | - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes |
|
|
83 | up some memory, but fixes "use feature" and similar modules |
|
|
84 | when used inside a Coro. |
|
|
85 | - allow zero as argument to Coro::Channel to mean the same thing |
|
|
86 | as no argument. this works with older versions as well, |
|
|
87 | but wasn't legal until now. |
|
|
88 | - slightly better c header file detection. |
|
|
89 | |
|
|
90 | 6.39 Mon Jun 2 00:00:08 CEST 2014 |
|
|
91 | - work around more incompatible changes in 5.20. |
|
|
92 | |
|
|
93 | 6.38 Sun Jun 1 21:54:23 CEST 2014 |
|
|
94 | - check that perl slots actually have enough space to hold |
|
|
95 | interpreter variables. |
|
|
96 | - untested port to perl 5.19 (64 bit tmps indices) (reported |
|
|
97 | by Andreas König). |
|
|
98 | - croak when cancel is called without a thread context. |
|
|
99 | |
|
|
100 | 6.37 Tue Mar 4 13:27:33 CET 2014 |
|
|
101 | - *sigh*, removed leftover debugging code from debugging a |
|
|
102 | perl bug, of all things. |
|
|
103 | |
|
|
104 | 6.36 Tue Mar 4 07:11:59 CET 2014 |
|
|
105 | - semaphores would not clear the destroy hook when interrupted |
|
|
106 | by ->throw, causing segfaults or worse. |
|
|
107 | - ->throw on a thread waiting for a semaphore did not acquire |
|
|
108 | the semaphore, but also didn't wake up other waiters, |
|
|
109 | possibly causing a deadlock. |
|
|
110 | - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess |
|
|
111 | to report a full stacktrace, which should help find out |
|
|
112 | where the actual call is. |
|
|
113 | - "atomically" destroy data in slf_destroy, because it is |
|
|
114 | the right thing to do, just in case. |
|
|
115 | - disable ecb.h libm dependency, to compile on ancient systems |
|
|
116 | or under adverse conditions. |
|
|
117 | |
|
|
118 | 6.33 Mon Nov 18 11:26:27 CET 2013 |
|
|
119 | - do not crash when freeing padlists with holes (in 5.18). |
|
|
120 | - tentative SVt_BIND 5.19 port/fix. |
|
|
121 | |
|
|
122 | 6.32 Tue Nov 5 15:35:35 CET 2013 |
|
|
123 | - use a new algorithm to derive padlists for perl 5.18. The old |
|
|
124 | one could lead to 0-pointer accesses inside perl (reported |
|
|
125 | by Darin McBride). |
|
|
126 | |
|
|
127 | 6.31 Thu May 9 07:39:48 CEST 2013 |
|
|
128 | - Coro::AIO requests would crash if the thread was ready'd |
|
|
129 | while the request was ongoing. |
|
|
130 | |
|
|
131 | 6.29 Wed May 8 02:55:18 CEST 2013 |
|
|
132 | - when an on_destroy handler destructs the coro currently being |
|
|
133 | destructed a perl scalar could be accessed after being freed, |
|
|
134 | likely causing a crash. |
|
|
135 | |
|
|
136 | 6.28 Wed Mar 6 06:58:02 CET 2013 |
| 7 | - manually copy existing __DIE__ and __WARN__ handlers so |
137 | - clean remnants of existing __DIE__ and __WARN__ handlers so |
