10
11 - (liebio) fix freebsd sendfile (Vanilla Hsu).
12 - (libeio) also fix darwin sendfile that suffered from a similar bug.
13 - add aio_statvfs as interface to statvfs/fstatvfs.
14
153.4 Sat Jan 2 15:13:04 CET 2010
16 - (libeio) max_poll_time was not properly converted to ticks.
17 - clarify cancel_subs description.
18 - IO::AIO::sendfile did not actually return the return value
19 from the sendfile call.
20 - implement aio_msync, aio_mtouch.
21 - (libeio) tentatively support darwin in sendfile.
22
233.31 Thu Nov 12 02:14:29 CET 2009
24 - fix result status documentation of aio_copy, aio_move.
25 - speed up object creation considerably by avoiding
26 hash lookups.
27
283.3 Wed Aug 5 13:52:58 CEST 2009
29 - use common::sense.
30 - use common schmorp.h header.
31 - allow integers (file descriptors) in addition to file handles.
32 - take advantage of linux' eventfd (but it seems slower on smp?).
33 - use poll not select on posix platforms.
34
353.261 Wed Jul 1 10:11:51 CEST 2009
36 - more 0S X workarounds (patch by Tokuhiro Matsuno).
37
383.26 Tue Jun 30 09:33:26 CEST 2009
39 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
40 try to work around this horribly broken OS in a somewhat hackish
41 way. might help other os's too.
42
433.25 Sat Jun 27 05:18:26 CEST 2009
44 - added IO::AIO::fadvise and IO::AIO::sendfile.
45 - (libeio) replaced quicksort+insertion sort by a tuned radix
46 sort + insertion sort, resulting in comparable runtime (usually
47 faster) to the old version, but without any ill side effects on
48 degenerated (for quicksort) data.
49 - (libeio) correctly sort dirs by inodes if we have perfect type
50 knowledge and DIRS_FIRST is used.
51 - (libeio) internally the wrong DT_* constants were used, but no
52 known system has differing EIO_DT_*/DT_* values, so not an issue.
53 - removed a (harmless) assert that was left over on the code
54 but should not have been.
55 - use more correct types (change IO length from IV to VAL64,
56 which makes a difference on systems without 64 bit perls).
57
583.23 Sat Jun 13 16:57:58 CEST 2009
59 - fix off-by-one bug in aio_readdir that was introduced in the
60 rushed 3.22 release.
61
623.22 Sat Jun 13 15:32:40 CEST 2009
63 - speed up readdirx sort algorithm slightly.
64 - bin/treescan was missing from distro tarball.
65
663.21 Fri Jun 12 18:45:53 CEST 2009
67 - new options --dirs and --files for treescan.
68 - install bin/treescan by default.
69 - (libeio) aio_readdir can now be cancelled while executing.
70 - fix a printf format string for 64 bit systems (could lead
71 to problems on big endian 64 bit systems).
72 - do not use qsort() but our own algorithm: glibc initialises
73 the whole locale and I/O subsystem inside qsort, causing
74 a stack overflow on 32 bit machines. The new sort uses much less
75 stack and is more than twice as fast in typical situations.
76
773.2 Sun Jun 7 20:30:05 CEST 2009
78 - (libeio) pwrite emulation was even more flawed than intended and did
79 not restore the file offset.
80 - add aio_readdirx, which can return inode and filetype and sort
81 the names in various ways.
82 - unfortunately, utime, chmod, chown on an open file that has just
83 been written can easily block, which caused aio_copy to block the
84 process. no more!
85 - no longer rely on dst path in aio_copy when futime is available.
86
873.19 Tue Apr 21 22:05:21 CEST 2009
88 - more perl 5.10 workarounds for aio_read and write.
89 - aio_write no longer modifies the sv (if possible).
90 - aio_read now works correctly with magic values.
91
923.18 Sun Apr 19 21:17:32 CEST 2009
93 - better diagnostics when some aio_* functions get passed an illegal fh.
94 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
95
963.17 Thu Nov 20 08:45:36 CET 2008
97 - (libeio) added aio_sync_file_range (untested).
98 - add aio_busy to @IO::AIO::AIO_REQ.
99
1003.16 Wed Oct 22 18:28:01 CEST 2008
101 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
102 part to improve portability to perl 5.8 (reported by szymon).
103
1043.15 Mon Oct 13 00:39:55 CEST 2008
105 - automatic removal of feeders was broken.
106 - (libeio) use a more robust method to detect whether a feeder
107 has added something to the group or not.
108
1093.1 Thu Oct 2 13:34:40 CEST 2008
110 - pre-deref the passed callback object, for increased speed
111 and decreased memory usage.
112 - call on_next_submit callback even for aio_group - impact unknown,
113 but seems more correct.
114 - $req->cb now returns the original callback.
115 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
116 requiring a thread switch.
117 - (libeio) status code of aio_futime and aio_utime was always passed 0.
118 - do some other ยต-optimisations.
8 119
93.07 Sat Aug 2 16:06:13 CEST 2008 1203.07 Sat Aug 2 16:06:13 CEST 2008
10 - do not include LIBS in autoconf tests. 121 - do not include LIBS in autoconf tests.
