|
9 | - experimental 5.24 compatibility changes. |
|
|
10 | - re-try JIT allocation without PROT_EXEC, to hopefully improve |
|
|
11 | portability. |
|
|
12 | |
|
|
13 | 6.511 Sun Jun 26 23:44:50 CEST 2016 |
|
|
14 | - make it compile with threaded perls again. |
|
|
15 | - simplify and speed up __DIE__ and __WARN__ handling. |
|
|
16 | |
|
|
17 | 6.51 Sat Jun 25 20:57:20 CEST 2016 |
|
|
18 | - 6.5 release didn't compile on most older perls due to |
|
|
19 | a logic error enabling experimental 5.24 code for all versions. |
|
|
20 | - since various broken or deficient patches float around |
|
|
21 | to work around the vtbl API breakage in perl, let's provide |
|
|
22 | our own workaround, which seems to be much less invasive |
|
|
23 | and more compatible than the approaches seen so far. YMMV. |
|
|
24 | - work around assertion failure in perl_destruct on 5.24 |
|
|
25 | (analyzed by Dave Mitchell). |
|
|
26 | |
|
|
27 | 6.5 Wed Jun 22 22:23:50 CEST 2016 |
|
|
28 | - swap_sv swapping order was not symmetrical, causing |
|
|
29 | wrong swaps when swap_sv was used multiple times on the |
|
|
30 | same sv in the same thread. |
|
|
31 | - swap_sv calls can now be undone by calling it again |
|
|
32 | with the same variables. |
|
|
33 | - swap_sv calls will now be undone in async_pool threads. |
|
|
34 | - split Coro::Semaphore::up/adjust into separate xs functions |
|
|
35 | for better error reporting, at slight codesize increase. |
|
|
36 | - (libcoro) arm assembly support, please test and report. |
|
|
37 | - adjust to PL_savestack changes in perl 5.24 (adapted from |
|
|
38 | the debian patch, which unfortunately gets it wrong). |
|
|
39 | |
|
|
40 | 6.49 Sat Oct 17 01:40:12 CEST 2015 |
|
|
41 | - throwing an exception to a thread waiting in |
|
|
42 | Coro::Handle using Coro::EV did not stop the watchers, |
|
|
43 | causing the next call to fail (testcase by Martin Pritchard). |
|
|
44 | - bump minimum perl version to 5.10. |
|
|
45 | |
|
|
46 | 6.48 Sun Oct 4 19:03:51 CEST 2015 |
|
|
47 | - fix memory leak when Coro::Handle uses Coro::EV internally |
|
|
48 | (testcase by Sten Sten). |
|
|
49 | - update code to libev 4 API (internally, Coro still used the |
|
|
50 | version 3 API calls). |
|
|
51 | - remove unused hv_sig. |
|
|
52 | |
|
|
53 | 6.47 Sat Jul 11 03:58:20 CEST 2015 |
|
|
54 | - swap_svs - NVs can be in the SV head beginning with 5.20. |
|
|
55 | |
|
|
56 | 6.46 Tue Jun 30 14:36:30 CEST 2015 |
|
|
57 | - restore portability to perls with windows fork emulation |
|
|
58 | (patch by Petr Písař). |
|
|
59 | |
|
|
60 | 6.45 Tue Jun 30 01:40:08 CEST 2015 |
|
|
61 | - restore portability to perl 5.16 and below. |
|
|
62 | |
|
|
63 | 6.44 Tue Jun 30 00:41:54 CEST 2015 |
|
|
64 | - avoid segfaulting (or worse) when tracing a canceled thread. |
|
|
65 | - the Event module silently broke it's public hook API, causing |
|
|
66 | failures on perls compiled with -Duselongdouble. Requiring |
|
|
67 | the latest version of Event because I don't know which release |
|
|
68 | changed this (it's not mentioned in the ChangeLog). |
|
|
69 | - allow xs level enterleave hooks via CoroAPI. |
|
|
70 | |
|
|
71 | 6.43 Thu Jun 4 15:38:14 CEST 2015 |
|
|
72 | - use stability canary. |
|
|
73 | - port to stableperl-5.22.0-1.001. |
|
|
74 | - update libecb. |
|
|
75 | |
|
|
76 | 6.42 Wed Feb 11 20:29:52 CET 2015 |
|
|
77 | - Coro::SemaphoreSet->try did not actually work (analyzed by |
|
|
78 | SATO Kentaro). |
|
|
79 | - upgrade libecb to be C11 compliant. |
|
|
80 | |
|
|
81 | 6.41 Sat Sep 6 22:08:46 CEST 2014 |
|
|
82 | - restore portability to perl 5.8.x. |
|
|
83 | - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes |
|
|
84 | up some memory, but fixes "use feature" and similar modules |
|
|
85 | when used inside a Coro. |
|
|
86 | - allow zero as argument to Coro::Channel to mean the same thing |
|
|
87 | as no argument. this works with older versions as well, |
|
|
88 | but wasn't legal until now. |
|
|
89 | - slightly better c header file detection. |
|
|
90 | |
|
|
91 | 6.39 Mon Jun 2 00:00:08 CEST 2014 |
|
|
92 | - work around more incompatible changes in 5.20. |
|
|
93 | |
|
|
94 | 6.38 Sun Jun 1 21:54:23 CEST 2014 |
|
|
95 | - check that perl slots actually have enough space to hold |
|
|
96 | interpreter variables. |
