|
|
10 | - *sigh*, removed leftover dbeugging code from debugging a |
|
|
11 | perl bug, of all things. |
|
|
12 | |
|
|
13 | 6.36 Tue Mar 4 07:11:59 CET 2014 |
|
|
14 | - semaphores would not clear the destroy hook when interrupted |
|
|
15 | by ->throw, causing segfaults or worse. |
|
|
16 | - ->throw on a thread waiting for a semaphore did not acquire |
|
|
17 | the semaphore, but also didn't wake up other waiters, |
|
|
18 | possibly causing a deadlock. |
|
|
19 | - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess |
|
|
20 | to report a full stacktrace, which should help find out |
|
|
21 | where the actual call is. |
|
|
22 | - "atomically" destroy data in slf_destroy, because it is |
|
|
23 | the right thing to do, just in case. |
|
|
24 | - disable ecb.h libm dependency, to compile on ancient systems |
|
|
25 | or under adverse conditions. |
|
|
26 | |
|
|
27 | 6.33 Mon Nov 18 11:26:27 CET 2013 |
|
|
28 | - do not crash when freeing padlists with holes (in 5.18). |
|
|
29 | - tentative SVt_BIND 5.19 port/fix. |
|
|
30 | |
|
|
31 | 6.32 Tue Nov 5 15:35:35 CET 2013 |
|
|
32 | - use a new algorithm to derive padlists for perl 5.18. The old |
|
|
33 | one could lead to 0-pointer accesses inside perl (reported |
|
|
34 | by Darin McBride). |
|
|
35 | |
|
|
36 | 6.31 Thu May 9 07:39:48 CEST 2013 |
|
|
37 | - Coro::AIO requests would crash if the thread was ready'd |
|
|
38 | while the request was ongoing. |
|
|
39 | |
|
|
40 | 6.29 Wed May 8 02:55:18 CEST 2013 |
|
|
41 | - when an on_destroy handler destructs the coro currently being |
|
|
42 | destructed a perl scalar could be accessed after being freed, |
|
|
43 | likely causing a crash. |
|
|
44 | |
|
|
45 | 6.28 Wed Mar 6 06:58:02 CET 2013 |
|
|
46 | - clean remnants of existing __DIE__ and __WARN__ handlers so |
|
|
47 | they lose their magic and will not cause segfaults later |
|
|
48 | (testcase by Andrey Sagulin). |
|
|
49 | - improved Coro::State documentation a bit. |
|
|
50 | - Coro::Debug::command now flushes the output. |
|
|
51 | - add hack detection code for x32 abi, because the braindead slugs |
|
|
52 | who designed that made it look exactly like x86_64 without |
|
|
53 | providing proper compile time symbols to test for it. as a result, |
|
|
54 | this detection cannot work reliably. |
|
|
55 | - valgrind stack registering was broken. |
|
|
56 | - do not rely on Time::HiRes anymore in Coro::Debug. |
|
|
57 | |
|
|
58 | 6.23 Fri Dec 7 23:36:37 CET 2012 |
|
|
59 | - use experimental fiber implementation on native windows |
|
|
60 | perls. |
|
|
61 | - use sizeof (void *) as multiplication factor for stack sizes, |
|
|
62 | to accomodate the totally braindamaged microsoft 64 bit "os". |
|
|
63 | - changed verifier host from win2k-ap510-32 to win7-sp516-32/64. |
|
|
64 | activeperl 5.16 crashes when PerlIO_define_layer is called due |
|
|
65 | to some bug in the perl dll, strawberry perl at least passes |
|
|
66 | the testsuite. |
|
|
67 | - implement Coro::Handle->peeraddr/host/port, for slightly |
|
|
68 | improved compatibility with LWP. |
|
|
69 | - implement 5.17 compatibility by almost blindly applying a |
|
|
70 | good-looking patch by Father Chrysostomos. |
|
|
71 | - move stack management functions into libcoro 3. |
|
|
72 | - libcoro version 3 "released". |
|
|
73 | - support magic values as timed_io_once args. |
|
|
74 | - recommend AnyEvent 7+ or EV 4+, also require EV |
|
|
75 | version 4 or newer for Coro::EV. |
|
|
76 | |
|
|
77 | 6.10 Tue Oct 9 01:14:27 CEST 2012 |
|
|
78 | - updated ecb.h, it had a typo that caused it to not compile on many |
|
|
79 | big endian systems (reported by many people). |
|
|
80 | - disable memory fences in ecb.h to improve portability. |
|
|
81 | |
|
|
82 | 6.09 Sat Oct 6 23:25:02 CEST 2012 |
|
|
83 | - Coro::EV I/O watchers were not interruptible by exceptions |
|
|
84 | (Coro::State::throw) (testcase by sten). |
|
|
85 | - ->throw now puts threads into the ready queue, as this seems to |
|
|
86 | be expected by existing code, and code that doesn't cope with spurious |
|
|
87 | wakeups needs fixing anyway. |
|
|
88 | - use fd -1 in mmap. |
|
|
89 | - cast I32 to int in error message printf. |
|
|
90 | - warn about broken so-called "hardened" kernels. |
|
|
91 | |
|
|
92 | 6.08 Fri Apr 13 12:05:47 CEST 2012 |
|
|
93 | - be more aggressive about exiting like perl does - formerly, |
|
|
94 | exiting from the non-main thread would not execute END blocks. |
|
|
95 | |
|
|
96 | 6.07 Fri Nov 11 21:21:48 CET 2011 |
|
|
97 | - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV). |
|
|
98 | - update ecb.h. |
| 6 | |
99 | |
