|
|
10 | - use a new algorithm to derive padlists for perl 5.18. The old |
|
|
11 | one could lead to 0-pointer accesses inside perl (reported |
|
|
12 | by Darin McBride). |
|
|
13 | |
|
|
14 | 6.31 Thu May 9 07:39:48 CEST 2013 |
|
|
15 | - Coro::AIO requests would crash if the thread was ready'd |
|
|
16 | while the request was ongoing. |
|
|
17 | |
|
|
18 | 6.29 Wed May 8 02:55:18 CEST 2013 |
|
|
19 | - when an on_destroy handler destructs the coro currently being |
|
|
20 | destructed a perl scalar could be accessed after being freed, |
|
|
21 | likely causing a crash. |
|
|
22 | |
|
|
23 | 6.28 Wed Mar 6 06:58:02 CET 2013 |
|
|
24 | - clean remnants of existing __DIE__ and __WARN__ handlers so |
|
|
25 | they lose their magic and will not cause segfaults later |
|
|
26 | (testcase by Andrey Sagulin). |
|
|
27 | - improved Coro::State documentation a bit. |
|
|
28 | - Coro::Debug::command now flushes the output. |
|
|
29 | - add hack detection code for x32 abi, because the braindead slugs |
|
|
30 | who designed that made it look exactly like x86_64 without |
|
|
31 | providing proper compile time symbols to test for it. as a result, |
|
|
32 | this detection cannot work reliably. |
|
|
33 | - valgrind stack registering was broken. |
|
|
34 | - do not rely on Time::HiRes anymore in Coro::Debug. |
|
|
35 | |
|
|
36 | 6.23 Fri Dec 7 23:36:37 CET 2012 |
|
|
37 | - use experimental fiber implementation on native windows |
|
|
38 | perls. |
|
|
39 | - use sizeof (void *) as multiplication factor for stack sizes, |
|
|
40 | to accomodate the totally braindamaged microsoft 64 bit "os". |
|
|
41 | - changed verifier host from win2k-ap510-32 to win7-sp516-32/64. |
|
|
42 | activeperl 5.16 crashes when PerlIO_define_layer is called due |
|
|
43 | to some bug in the perl dll, strawberry perl at least passes |
|
|
44 | the testsuite. |
|
|
45 | - implement Coro::Handle->peeraddr/host/port, for slightly |
|
|
46 | improved compatibility with LWP. |
|
|
47 | - implement 5.17 compatibility by almost blindly applying a |
|
|
48 | good-looking patch by Father Chrysostomos. |
|
|
49 | - move stack management functions into libcoro 3. |
|
|
50 | - libcoro version 3 "released". |
|
|
51 | - support magic values as timed_io_once args. |
|
|
52 | - recommend AnyEvent 7+ or EV 4+, also require EV |
|
|
53 | version 4 or newer for Coro::EV. |
|
|
54 | |
|
|
55 | 6.10 Tue Oct 9 01:14:27 CEST 2012 |
|
|
56 | - updated ecb.h, it had a typo that caused it to not compile on many |
|
|
57 | big endian systems (reported by many people). |
|
|
58 | - disable memory fences in ecb.h to improve portability. |
|
|
59 | |
|
|
60 | 6.09 Sat Oct 6 23:25:02 CEST 2012 |
|
|
61 | - Coro::EV I/O watchers were not interruptible by exceptions |
|
|
62 | (Coro::State::throw) (testcase by sten). |
|
|
63 | - ->throw now puts threads into the ready queue, as this seems to |
|
|
64 | be expected by existing code, and code that doesn't cope with spurious |
|
|
65 | wakeups needs fixing anyway. |
|
|
66 | - use fd -1 in mmap. |
|
|
67 | - cast I32 to int in error message printf. |
|
|
68 | - warn about broken so-called "hardened" kernels. |
|
|
69 | |
|
|
70 | 6.08 Fri Apr 13 12:05:47 CEST 2012 |
|
|
71 | - be more aggressive about exiting like perl does - formerly, |
|
|
72 | exiting from the non-main thread would not execute END blocks. |
|
|
73 | |
|
|
74 | 6.07 Fri Nov 11 21:21:48 CET 2011 |
|
|
75 | - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV). |
|
|
76 | - update ecb.h. |
|
|
77 | |
|
|
78 | 6.06 Mon Aug 8 23:59:48 CEST 2011 |
|
|
79 | - cygwin unfortunately patches the stack at runtime, so we use the pthreads |
|
|
80 | backend, which is an order of magnitude slower. unfortunately, cygwins |
|
|
81 | pthread implementation isn't very complete either, so allocate the stack |
|
|
82 | twice just to be sure. |
|
|
83 | (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS, |
|
|
84 | in its ithreaded perl - best recompile cygwin and use the 'w'indows |
|
|
85 | backend for much better performance. also disable ithreads for |
|
|
86 | even better performance...). |
|
|
87 | |
|
|
88 | 6.05 Thu Aug 4 21:36:36 CEST 2011 |
|
|
89 | - blush, condvar values would not be propagated from send to recv anymore |
|
|
90 | (reported by Chip Salzenberg). |
|
|
91 | - use exponential increase for the readline buffer length in |
|
|
92 | Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes. |
|
|
93 | |
|
|
94 | 6.04 Wed Aug 3 17:15:45 CEST 2011 |
|
|
95 | - use even more efficient and more compatible condvars for |
|
|
96 | compatibility to AnyEvent 6.x :) |
|
|
97 | - more inconsequential ecb.h updates. |
|
|
98 | |
|
|
99 | 6.03 Wed Aug 3 11:41:30 CEST 2011 |
|
|
100 | - change how Coro patches AnyEvent condvars for compatibility to |
|
|
101 | AnyEvent 6.x. |
|
|
102 | - update ecb.h, to no longer include <pthread.h> in case WinNT.h |
|
|
103 | hasn't been included. |
|
|
104 | |
|
|
105 | 6.02 Wed Jul 13 04:35:19 CEST 2011 |
|
|
106 | - "improve portability to Gentoo" - gentoo manages to put perl variables |
|
|
107 | in memory areas that are farther than 2gb apart, which the jit couldn't |
|
|
108 | handle and barfed. now it's just a bit slower on gentoo and similar |
|
|
109 | systems. |
|
|
110 | |
|
|
111 | 6.01 Sun Jul 3 12:31:14 CEST 2011 |
|
|
112 | - workarounds are good, but the test for whether pthreads are used |
|
|
113 | was not good. thisone should be better. |
|
|
114 | - check differently whether gcc generates cfi instructions itself. |
|
|
115 | |
|
|
