|
|
11 | - restore portability to perl 5.8.x. |
|
|
12 | - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes |
|
|
13 | up some memory, but fixes "use feature" and similar modules |
|
|
14 | when used inside a Coro. |
|
|
15 | - allow zero as argument to Coro::Channel to mean the same thing |
|
|
16 | as no argument. this works with older versions as well, |
|
|
17 | but wasn't legal until now. |
|
|
18 | - slightly better c header file detection. |
|
|
19 | |
|
|
20 | 6.39 Mon Jun 2 00:00:08 CEST 2014 |
|
|
21 | - work around more incompatible changes in 5.20. |
|
|
22 | |
|
|
23 | 6.38 Sun Jun 1 21:54:23 CEST 2014 |
|
|
24 | - check that perl slots actually have enough space to hold |
|
|
25 | interpreter variables. |
|
|
26 | - untested port to perl 5.19 (64 bit tmps indices) (reported |
|
|
27 | by Andreas König). |
|
|
28 | - croak when cancel is called without a thread context. |
|
|
29 | |
|
|
30 | 6.37 Tue Mar 4 13:27:33 CET 2014 |
|
|
31 | - *sigh*, removed leftover debugging code from debugging a |
|
|
32 | perl bug, of all things. |
|
|
33 | |
|
|
34 | 6.36 Tue Mar 4 07:11:59 CET 2014 |
|
|
35 | - semaphores would not clear the destroy hook when interrupted |
|
|
36 | by ->throw, causing segfaults or worse. |
|
|
37 | - ->throw on a thread waiting for a semaphore did not acquire |
|
|
38 | the semaphore, but also didn't wake up other waiters, |
|
|
39 | possibly causing a deadlock. |
|
|
40 | - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess |
|
|
41 | to report a full stacktrace, which should help find out |
|
|
42 | where the actual call is. |
|
|
43 | - "atomically" destroy data in slf_destroy, because it is |
|
|
44 | the right thing to do, just in case. |
|
|
45 | - disable ecb.h libm dependency, to compile on ancient systems |
|
|
46 | or under adverse conditions. |
|
|
47 | |
|
|
48 | 6.33 Mon Nov 18 11:26:27 CET 2013 |
|
|
49 | - do not crash when freeing padlists with holes (in 5.18). |
|
|
50 | - tentative SVt_BIND 5.19 port/fix. |
|
|
51 | |
|
|
52 | 6.32 Tue Nov 5 15:35:35 CET 2013 |
|
|
53 | - use a new algorithm to derive padlists for perl 5.18. The old |
|
|
54 | one could lead to 0-pointer accesses inside perl (reported |
|
|
55 | by Darin McBride). |
|
|
56 | |
|
|
57 | 6.31 Thu May 9 07:39:48 CEST 2013 |
|
|
58 | - Coro::AIO requests would crash if the thread was ready'd |
|
|
59 | while the request was ongoing. |
|
|
60 | |
|
|
61 | 6.29 Wed May 8 02:55:18 CEST 2013 |
|
|
62 | - when an on_destroy handler destructs the coro currently being |
|
|
63 | destructed a perl scalar could be accessed after being freed, |
|
|
64 | likely causing a crash. |
|
|
65 | |
|
|
66 | 6.28 Wed Mar 6 06:58:02 CET 2013 |
|
|
67 | - clean remnants of existing __DIE__ and __WARN__ handlers so |
|
|
68 | they lose their magic and will not cause segfaults later |
|
|
69 | (testcase by Andrey Sagulin). |
