93.1 10 - use common::sense.
11 - use common schmorp.h header.
12 - allow integers (file descriptors) in addition to file handles.

143.261 Wed Jul 1 10:11:51 CEST 2009
15 - more OS X workarounds (patch by Tokuhiro Matsuno).
16
173.26 Tue Jun 30 09:33:26 CEST 2009
18 - os x of course claims posix 2008 but lacks posix_fadvise. try to work
19 around this horribly broken OS in a somewhat hackish way. might help
20 other os's too.
21
223.25 Sat Jun 27 05:18:26 CEST 2009
23 - added IO::AIO::fadvise and IO::AIO::sendfile.
24 - (libeio) replaced quicksort+insertion sort by a tuned radix
25 sort + insertion sort, resulting in comparable runtime (usually
26 faster) to the old version, but without any ill side effects on
27 degenerated (for quicksort) data.
28 - (libeio) correctly sort dirs by inodes if we have perfect type
29 knowledge and DIRS_FIRST is used.
30 - (libeio) internally the wrong DT_* constants were used, but no
31 known system has differing EIO_DT_*/DT_* values, so not an issue.
32 - removed a (harmless) assert that was left over on the code
33 but should not have been.
34 - use more correct types (change IO length from IV to VAL64,
35 which makes a difference on systems without 64 bit perls).
36
373.23 Sat Jun 13 16:57:58 CEST 2009
38 - fix off-by-one bug in aio_readdir that was introduced in the
39 rushed 3.22 release.
40
413.22 Sat Jun 13 15:32:40 CEST 2009
42 - speed up readdirx sort algorithm slightly.
43 - bin/treescan was missing from distro tarball.
44
453.21 Fri Jun 12 18:45:53 CEST 2009
46 - new options --dirs and --files for treescan.
47 - install bin/treescan by default.
48 - (libeio) aio_readdir can now be cancelled while executing.
49 - fix a printf format string for 64 bit systems (could lead
50 to problems on big endian 64 bit systems).
51 - do not use qsort() but our own algorithm: glibc initialises
52 the whole locale and I/O subsystem inside qsort, causing
53 a stack overflow on 32 bit machines. The new sort uses much less
54 stack and is more than twice as fast in typical situations.
55
563.2 Sun Jun 7 20:30:05 CEST 2009
57 - (libeio) pwrite emulation was even more flawed than intended and did
58 not restore the file offset.
59 - add aio_readdirx, which can return inode and filetype and sort
60 the names in various ways.
61 - unfortunately, utime, chmod, chown on an open file that has just
62 been written can easily block, which caused aio_copy to block the
63 process. no more!
64 - no longer rely on dst path in aio_copy when futime is available.
65
663.19 Tue Apr 21 22:05:21 CEST 2009
67 - more perl 5.10 workarounds for aio_read and write.
68 - aio_write no longer modifies the sv (if possible).
69 - aio_read now works correctly with magic values.
70
713.18 Sun Apr 19 21:17:32 CEST 2009
72 - better diagnostics when some aio_* functions get passed an illegal fh.
73 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
74
753.17 Thu Nov 20 08:45:36 CET 2008
76 - (libeio) added aio_sync_file_range (untested).
77 - add aio_busy to @IO::AIO::AIO_REQ.
78
793.16 Wed Oct 22 18:28:01 CEST 2008
80 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
81 part to improve portability to perl 5.8 (reported by szymon).
82
833.15 Mon Oct 13 00:39:55 CEST 2008
84 - automatic removal of feeders was broken.
85 - (libeio) use a more robust method to detect whether a feeder
86 has added something to the group or not.
87
883.1 Thu Oct 2 13:34:40 CEST 2008
10 - pre-deref the passed callback object, for increased speed 89 - pre-deref the passed callback object, for increased speed
11 and decreased memory usage. 90 and decreased memory usage.
12 - call on_next_submit callback even for aio_group - impact unknown, 91 - call on_next_submit callback even for aio_group - impact unknown,
13 but seems more correct. 92 but seems more correct.
14 - $req->cb now returns the original callback. 93 - $req->cb now returns the original callback.
