10 - (libeio) max_poll_time was not properly converted to ticks.
11 - clarify cancel_subs description.
12 - IO::AIO::sendfile did not actually return the return value
13 from the sendfile call.
14
153.31 Thu Nov 12 02:14:29 CET 2009
16 - fix result status documentation of aio_copy, aio_move.
17 - speed up object creation considerably by avoiding
18 hash lookups.
19
203.3 Wed Aug 5 13:52:58 CEST 2009
21 - use common::sense.
22 - use common schmorp.h header.
23 - allow integers (file descriptors) in addition to file handles.
24 - take advantage of linux' eventfd (but it seems slower on smp?).
25 - use poll not select on posix platforms.
26
273.261 Wed Jul 1 10:11:51 CEST 2009
28 - more 0S X workarounds (patch by Tokuhiro Matsuno).
29
303.26 Tue Jun 30 09:33:26 CEST 2009
31 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
32 try to work around this horribly broken OS in a somewhat hackish
33 way. might help other os's too.
34
353.25 Sat Jun 27 05:18:26 CEST 2009
36 - added IO::AIO::fadvise and IO::AIO::sendfile.
37 - (libeio) replaced quicksort+insertion sort by a tuned radix
38 sort + insertion sort, resulting in comparable runtime (usually
39 faster) to the old version, but without any ill side effects on
40 degenerated (for quicksort) data.
41 - (libeio) correctly sort dirs by inodes if we have perfect type
42 knowledge and DIRS_FIRST is used.
43 - (libeio) internally the wrong DT_* constants were used, but no
44 known system has differing EIO_DT_*/DT_* values, so not an issue.
45 - removed a (harmless) assert that was left over on the code
46 but should not have been.
47 - use more correct types (change IO length from IV to VAL64,
48 which makes a difference on systems without 64 bit perls).
49
503.23 Sat Jun 13 16:57:58 CEST 2009
51 - fix off-by-one bug in aio_readdir that was introduced in the
52 rushed 3.22 release.
53
543.22 Sat Jun 13 15:32:40 CEST 2009
55 - speed up readdirx sort algorithm slightly.
56 - bin/treescan was missing from distro tarball.
57
583.21 Fri Jun 12 18:45:53 CEST 2009
59 - new options --dirs and --files for treescan.
60 - install bin/treescan by default.
61 - (libeio) aio_readdir can now be cancelled while executing.
62 - fix a printf format string for 64 bit systems (could lead
63 to problems on big endian 64 bit systems).
64 - do not use qsort() but our own algorithm: glibc initialises
65 the whole locale and I/O subsystem inside qsort, causing
66 a stack overflow on 32 bit machines. The new sort uses much less
67 stack and is more than twice as fast in typical situations.
68
693.2 Sun Jun 7 20:30:05 CEST 2009
70 - (libeio) pwrite emulation was even more flawed than intended and did
71 not restore the file offset.
72 - add aio_readdirx, which can return inode and filetype and sort
73 the names in various ways.
74 - unfortunately, utime, chmod, chown on an open file that has just
75 been written can easily block, which caused aio_copy to block the
76 process. no more!
77 - no longer rely on dst path in aio_copy when futime is available.
78
793.19 Tue Apr 21 22:05:21 CEST 2009
80 - more perl 5.10 workarounds for aio_read and write.
81 - aio_write no longer modifies the sv (if possible).
82 - aio_read now works correctly with magic values.
83
843.18 Sun Apr 19 21:17:32 CEST 2009
85 - better diagnostics when some aio_* functions get passed an illegal fh.
86 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
87
883.17 Thu Nov 20 08:45:36 CET 2008
89 - (libeio) added aio_sync_file_range (untested).
90 - add aio_busy to @IO::AIO::AIO_REQ.
91
923.16 Wed Oct 22 18:28:01 CEST 2008
93 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
94 part to improve portability to perl 5.8 (reported by szymon).
95
963.15 Mon Oct 13 00:39:55 CEST 2008
97 - automatic removal of feeders was broken.
98 - (libeio) use a more robust method to detect whether a feeder
99 has added something to the group or not.
100
1013.1 Thu Oct 2 13:34:40 CEST 2008
102 - pre-deref the passed callback object, for increased speed
103 and decreased memory usage.
104 - call on_next_submit callback even for aio_group - impact unknown,
105 but seems more correct.
106 - $req->cb now returns the original callback.
107 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
108 requiring a thread switch.
109 - (libeio) status code of aio_futime and aio_utime was always passed 0.
110 - do some other ยต-optimisations.
111
1123.07 Sat Aug 2 16:06:13 CEST 2008
113 - do not include LIBS in autoconf tests.

93.06 Tue Jul 15 12:41:32 CEST 2008 1153.06 Tue Jul 15 12:41:32 CEST 2008
10 - move preadwritelock definition before it's first reference, 116 - move preadwritelock definition before it's first reference,
11 to make it compile again on broken platforms (they still exist) 117 to make it compile again on broken platforms (they still exist)
12 or badly cofngiured perls (redhat...), reported by Rob Bloodgood. 118 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
