|
10 | - fix memory leak when Coro::Handle uses Coro::EV internally |
|
|
11 | (testcase by Sten Sten). |
|
|
12 | - update code to libev 4 API (internally, Coro still used the |
|
|
13 | version 3 API calls). |
|
|
14 | - remove unused hv_sig. |
|
|
15 | |
|
|
16 | 6.47 Sat Jul 11 03:58:20 CEST 2015 |
|
|
17 | - swap_svs - NVs can be in the SV head beginning with 5.20. |
|
|

|
19 | 6.46 Tue Jun 30 14:36:30 CEST 2015 |
|
|
20 | - restore portability to perls with windows fork emulation |
|
|
21 | (patch by Petr Písař). |
|
|
22 | |
|
|
23 | 6.45 Tue Jun 30 01:40:08 CEST 2015 |
|
|
24 | - restore portability to perl 5.16 and below. |
|
|
25 | |
|
|
26 | 6.44 Tue Jun 30 00:41:54 CEST 2015 |
|
|
27 | - avoid segfaulting (or worse) when tracing a canceled thread. |
|
|
28 | - the Event module silently broke it's public hook API, causing |
|
|
29 | failures on perls compiled with -Duselongdouble. Requiring |
|
|
30 | the latest version of Event because I don't know which release |
|
|
31 | changed this (it's not mentioned in the ChangeLog). |
|
|
32 | - allow xs level enterleave hooks via CoroAPI. |
|
|
33 | |
|
|
34 | 6.43 Thu Jun 4 15:38:14 CEST 2015 |
|
|
35 | - use stability canary. |
|
|
36 | - port to stableperl-5.22.0-1.001. |
|
|
37 | - update libecb. |
|
|
38 | |
|
|
39 | 6.42 Wed Feb 11 20:29:52 CET 2015 |
|
|
40 | - Coro::SemaphoreSet->try did not actually work (analyzed by |
|
|
41 | SATO Kentaro). |
|
|
42 | - upgrade libecb to be C11 compliant. |
|
|
43 | |
|
|
44 | 6.41 Sat Sep 6 22:08:46 CEST 2014 |
|
|
45 | - restore portability to perl 5.8.x. |
|
|
46 | - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes |
|
|
47 | up some memory, but fixes "use feature" and similar modules |
|
|
48 | when used inside a Coro. |
|
|
49 | - allow zero as argument to Coro::Channel to mean the same thing |
|
|
50 | as no argument. this works with older versions as well, |
|
|
51 | but wasn't legal until now. |
|
|
52 | - slightly better c header file detection. |
|
|
53 | |
|
|
54 | 6.39 Mon Jun 2 00:00:08 CEST 2014 |
|
|
55 | - work around more incompatible changes in 5.20. |
|
|
56 | |
|
|
57 | 6.38 Sun Jun 1 21:54:23 CEST 2014 |
|
|
58 | - check that perl slots actually have enough space to hold |
|
|
59 | interpreter variables. |
|
|
60 | - untested port to perl 5.19 (64 bit tmps indices) (reported |
|
|
61 | by Andreas König). |
|
|
62 | - croak when cancel is called without a thread context. |
|
|
63 | |
|
|
64 | 6.37 Tue Mar 4 13:27:33 CET 2014 |
|
|
65 | - *sigh*, removed leftover debugging code from debugging a |
|
|
66 | perl bug, of all things. |
|
|
67 | |
|
|
68 | 6.36 Tue Mar 4 07:11:59 CET 2014 |
|
|
69 | - semaphores would not clear the destroy hook when interrupted |
|
|
70 | by ->throw, causing segfaults or worse. |
|
|
71 | - ->throw on a thread waiting for a semaphore did not acquire |
|
|
72 | the semaphore, but also didn't wake up other waiters, |
|
|
73 | possibly causing a deadlock. |
|
|
74 | - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess |
|
|
75 | to report a full stacktrace, which should help find out |
|
|
76 | where the actual call is. |
|
|
77 | - "atomically" destroy data in slf_destroy, because it is |
|
|
78 | the right thing to do, just in case. |
|
|
79 | - disable ecb.h libm dependency, to compile on ancient systems |
|
|
80 | or under adverse conditions. |
|
|
81 | |
|
|
82 | 6.33 Mon Nov 18 11:26:27 CET 2013 |
|
|
83 | - do not crash when freeing padlists with holes (in 5.18). |
|
|
84 | - tentative SVt_BIND 5.19 port/fix. |
|
|
85 | |
|
|
86 | 6.32 Tue Nov 5 15:35:35 CET 2013 |
|
|
87 | - use a new algorithm to derive padlists for perl 5.18. The old |
|
|
88 | one could lead to 0-pointer accesses inside perl (reported |
|
|
89 | by Darin McBride). |
|
|
90 | |
|
|
91 | 6.31 Thu May 9 07:39:48 CEST 2013 |
|
|
92 | - Coro::AIO requests would crash if the thread was ready'd |
|
|
93 | while the request was ongoing. |
|
|
94 | |
|
|
95 | 6.29 Wed May 8 02:55:18 CEST 2013 |
|
|
96 | - when an on_destroy handler destructs the coro currently being |
|
|
97 | destructed a perl scalar could be accessed after being freed, |
|
|
98 | likely causing a crash. |
|
|
99 | |
|
|
100 | 6.28 Wed Mar 6 06:58:02 CET 2013 |
|
|
101 | - clean remnants of existing __DIE__ and __WARN__ handlers so |
|
|
102 | they lose their magic and will not cause segfaults later |
|
|
103 | (testcase by Andrey Sagulin). |
7 | - improved Coro::State documentation a bit. |

105 | - Coro::Debug::command now flushes the output. |

106 | - add hack detection code for x32 abi, because the braindead slugs |
|
|
107 | who designed that made it look exactly like x86_64 without |
|
|
108 | providing proper compile time symbols to test for it. as a result, |
|
|
109 | this detection cannot work reliably. |
|
|
110 | - valgrind stack registering was broken. |
|
|
111 | - do not rely on Time::HiRes anymore in Coro::Debug. |
