9 | 3.15 Mon Oct 13 00:39:55 CEST 2008 |
|
|
10 | - automatic removal of feeders was broken. |
|
|
11 | - (libeio) use a more robust method to detect whether a feeder |
|
|
12 | has added something to the group or not. |
|
|
13 | |
|
|
14 | 3.1 Thu Oct 2 13:34:40 CEST 2008 |
|
|
15 | - pre-deref the passed callback object, for increased speed |
|
|
16 | and decreased memory usage. |
|
|
17 | - call on_next_submit callback even for aio_group - impact unknown, |
|
|
18 | but seems more correct. |
|
|
19 | - $req->cb now returns the original callback. |
|
|
20 | - (libeio) pass EIO_GROUP/aio_group requests through the queue without |
|
|
21 | requiring a thread switch. |
|
|
22 | - (libeio) status code of aio_futime and aio_utime was always passed 0. |
|
|
23 | - do some other ยต-optimisations. |
|
|
24 | |
|
|
25 | 3.07 Sat Aug 2 16:06:13 CEST 2008 |
|
|
26 | - do not include LIBS in autoconf tests. |
|
|
27 | |
|
|
28 | 3.06 Tue Jul 15 12:41:32 CEST 2008 |
|
|
29 | - move preadwritelock definition before it's first reference, |
|
|
30 | to make it compile again on broken platforms (they still exist) |
|
|
31 | or badly cofngiured perls (redhat...), reported by Rob Bloodgood. |
|
|
32 | |
|
|
33 | 3.05 Thu Jun 19 23:23:52 CEST 2008 |
|
|
34 | - work around perl overriding readdir etc. with thread-unsafe |
|
|
35 | (sic!) versions. |
|
|
36 | |
|
|
37 | 3.04 Wed Jun 18 01:35:38 CEST 2008 |
|
|
38 | - (libeio) fix eio_mknod, which confused it's arguments. |
|
|
39 | - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this |
|
|
40 | is stupid. |
|
|
41 | - (libeio) fix eio__readahead prototype, patch by Jost Krieger. |
|
|
42 | - (libeio) fix a bug that could potentially cause IO::AIO |
|
|
43 | not to get initialised properly. |
|
|
44 | |
|
|
45 | 3.03 Thu May 29 05:33:30 CEST 2008 |
|
|
46 | - (libeio) correctly call pthread_attr_destroy (). |
|
|
47 | - (libeio) work around broken bsd headers once more. |
|
|
48 | - reduce shared library size again by not including wrappers. |
|
|
49 | - max_outstanding could cause poll to enter a busy-waiting loop. |
|
|
50 | - document the new IO::AIO::poll_cb result value. |
|
|
51 | |
|
|
52 | 3.02 Mon May 12 02:32:02 CEST 2008 |
|
|
53 | - fix a memory leak on aio_readlink. |
|
|
54 | - bring back working fchmod. |
|
|
55 | - nop and busy now set result to 0. |
|
|
56 | - set errno to ENOMEM when allocation fails. |
|
|
57 | |
|
|
58 | 3.01 Sun May 11 03:07:03 CEST 2008 |
|
|
59 | - (libeio) make it compile on systems without readahead or readdir_r. |
|
|
60 | - (libeio) improve configure check for readahead availability. |
|
|
61 | - do not try to link against -lrt. |
|
|
62 | - use a separate configure script for IO::AIO (not the libeio one). |
|
|
63 | |
|
|
64 | 3.0 Sun May 11 00:57:14 CEST 2008 |
|
|
65 | - added bin/treescan to the distribution. |
|
|
66 | - switched to using libeio. |
|
|
67 | - LOTS OF INCOMPATIBLE CHANGES: |
|
|
68 | - remove signal functionality, it is not worth the effort. |
|
|
69 | - max_outstanding no longer returns the previous number of requests. |
|
|
70 | - poll_cb no longer returns number of requests. |
|
|
71 | |
|
|
72 | 2.62 Sat Apr 26 13:59:33 CEST 2008 |
|
|
73 | - port to solaris perls configured for old posix |
|
|
74 | (analysed by Jost Krieger). |
|
|
75 | - keep a reference to the perl filehandle object in aio_close, |
|
|
76 | so it doesn't get closed prematurely, leading to ugly races. |
|
|
77 | |
|
|
78 | 2.61 Wed Apr 16 18:45:02 CEST 2008 |
|
|
79 | - fix treescan output duplication and improve output ordering. |
|
|
80 | also display files given on the commandline. |
|
|
81 | - use a different algorithm for aio_close that is faster |
|
|
82 | and probably has even lower chances of blocking. |
|
|
83 | - do our own stack memory management for threads - linux |
|
|
84 | allocates outrageous amounts of VM (not so bad unless you |
|
|
85 | use mlockall...), which severely limits the number of threads |
|
|
86 | on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN |
|
|
87 | and 4096 * sizeof (long) (usually this is 16..64k). |
|
|
88 | |
|
|
89 | 2.6 Sun Mar 30 08:28:11 CEST 2008 |
| 10 | - added aio_sync. |
90 | - added aio_sync. |
|
|
91 | - added aio_pathsync. |
|
|
92 | - fix prototypes of (void) functions. |

94 | 2.51 Sat Oct 6 16:04:54 CEST 2007 |
| 13 | - perlio isn't generally threadsafe, so aio_close could not work reliably. |
