| 9 | 3.0 |
9 | - new options --dirs and --files for treescan. |
| 10 | - lots of incompatible changes: |
10 | |
|
|
11 | 3.2 Sun Jun 7 20:30:05 CEST 2009 |
|
|
12 | - (libeio) pwrite emulation was even more flawed than intended and did |
|
|
13 | not restore the file offset. |
|
|
14 | - add aio_readdirx, which can return inode and filetype and sort |
|
|
15 | the names in various ways. |
|
|
16 | - unfortunately, utime, chmod, chown on an open file that has just |
|
|
17 | been written can easily block, which caused aio_copy to block the |
|
|
18 | process. no more! |
|
|
19 | - no longer rely on dst path in aio_copy when futime is available. |
|
|
20 | |
|
|
21 | 3.19 Tue Apr 21 22:05:21 CEST 2009 |
|
|
22 | - more perl 5.10 workarounds for aio_read and write. |
|
|
23 | - aio_write no longer modifies the sv (if possible). |
|
|
24 | - aio_read now works correctly with magic values. |
|
|
25 | |
|
|
26 | 3.18 Sun Apr 19 21:17:32 CEST 2009 |
|
|
27 | - better diagnostics when some aio_* functions get passed an illegal fh. |
|
|
28 | - try to avoid crashes due to incompatible 5.10 API changes. grmbl. |
|
|
29 | |
|
|
30 | 3.17 Thu Nov 20 08:45:36 CET 2008 |
|
|
31 | - (libeio) added aio_sync_file_range (untested). |
|
|
32 | - add aio_busy to @IO::AIO::AIO_REQ. |
|
|
33 | |
|
|
34 | 3.16 Wed Oct 22 18:28:01 CEST 2008 |
|
|
35 | - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical |
|
|
36 | part to improve portability to perl 5.8 (reported by szymon). |
|
|
37 | |
|
|
38 | 3.15 Mon Oct 13 00:39:55 CEST 2008 |
|
|
39 | - automatic removal of feeders was broken. |
|
|
40 | - (libeio) use a more robust method to detect whether a feeder |
|
|
41 | has added something to the group or not. |
|
|
42 | |
|
|
43 | 3.1 Thu Oct 2 13:34:40 CEST 2008 |
|
|
44 | - pre-deref the passed callback object, for increased speed |
|
|
45 | and decreased memory usage. |
|
|
46 | - call on_next_submit callback even for aio_group - impact unknown, |
|
|
47 | but seems more correct. |
|
|
48 | - $req->cb now returns the original callback. |
|
|
49 | - (libeio) pass EIO_GROUP/aio_group requests through the queue without |
|
|
50 | requiring a thread switch. |
|
|
51 | - (libeio) status code of aio_futime and aio_utime was always passed 0. |
|
|
52 | - do some other ยต-optimisations. |
|
|
53 | |
|
|
54 | 3.07 Sat Aug 2 16:06:13 CEST 2008 |
|
|
55 | - do not include LIBS in autoconf tests. |
|
|
56 | |
|
|
57 | 3.06 Tue Jul 15 12:41:32 CEST 2008 |
|
|
58 | - move preadwritelock definition before it's first reference, |
|
|
59 | to make it compile again on broken platforms (they still exist) |
|
|
60 | or badly cofngiured perls (redhat...), reported by Rob Bloodgood. |
|
|
61 | |
|
|
62 | 3.05 Thu Jun 19 23:23:52 CEST 2008 |
|

|

|
65 | |
|

|
|
67 | - (libeio) fix eio_mknod, which confused it's arguments. |
|
|
68 | - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this |
|
|
69 | is stupid. |
|
|
70 | - (libeio) fix eio__readahead prototype, patch by Jost Krieger. |
|
|
71 | - (libeio) fix a bug that could potentially cause IO::AIO |
|
|
72 | not to get initialised properly. |
|
|
73 | |
|
|
74 | 3.03 Thu May 29 05:33:30 CEST 2008 |

|
80 | |
|
|
81 | 3.02 Mon May 12 02:32:02 CEST 2008 |
|
|
82 | - fix a memory leak on aio_readlink. |
|
|
83 | - bring back working fchmod. |

87 | 3.01 Sun May 11 03:07:03 CEST 2008 |

|
|
90 | - do not try to link against -lrt. |
|
|

|
|
92 | |
|
|
93 | 3.0 Sun May 11 00:57:14 CEST 2008 |
