12 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-documented
13 them.
14
153.65 Wed Mar 31 02:45:05 CEST 2010
16 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
17 cut off long pathnames in aio_readlink (based on patch by
18 Rasmus Andersson).
19 - a double fork partially killed the event pipe (great testcase
20 by dormando). affects IO::AIO, BDB and Async::Interrupt.
21 - suck steve's dick and rename our symbols to avoid colliding
22 with nonstandard identifier spam on the broken os x pseudo-os.
23 affects IO::AIO and BDB.
24
253.6 Mon Jan 11 00:43:39 CET 2010
26 - (libeio) more fixes for the freebsd/apple sendfile - broken by
27 manpage standards, but apparently correct accoridng to actual
28 kernel sources.
29 - add IO::AIO::mmap/munmap support.
30 - add IO::AIO::m(un)lockall support.
31 - clean up manpage.
32
333.5 Thu Jan 7 21:25:04 CET 2010
34 - (liebio) fix freebsd sendfile (Vanilla Hsu).
35 - (libeio) also fix darwin sendfile that suffered from a similar bug.
36 - add aio_statvfs as interface to statvfs/fstatvfs.
37 - work around buggy symlink() on cygwin in the testsuite.
38 - wtf. freebsd-8.0 actually passes the testsuite! I knew
39 they could implement fork and semaphores one day! cheers!
40
413.4 Sat Jan 2 15:13:04 CET 2010
42 - (libeio) max_poll_time was not properly converted to ticks.
43 - clarify cancel_subs description.
44 - IO::AIO::sendfile did not actually return the return value
45 from the sendfile call.
46 - implement aio_msync, aio_mtouch.
47 - (libeio) tentatively support darwin in sendfile.
48
493.31 Thu Nov 12 02:14:29 CET 2009
50 - fix result status documentation of aio_copy, aio_move.
51 - speed up object creation considerably by avoiding
52 hash lookups.
53
543.3 Wed Aug 5 13:52:58 CEST 2009
55 - use common::sense.
56 - use common schmorp.h header.
57 - allow integers (file descriptors) in addition to file handles.
58 - take advantage of linux' eventfd (but it seems slower on smp?).
59 - use poll not select on posix platforms.
60
613.261 Wed Jul 1 10:11:51 CEST 2009
62 - more 0S X workarounds (patch by Tokuhiro Matsuno).
63
643.26 Tue Jun 30 09:33:26 CEST 2009
65 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
66 try to work around this horribly broken OS in a somewhat hackish
67 way. might help other os's too.
68
693.25 Sat Jun 27 05:18:26 CEST 2009
70 - added IO::AIO::fadvise and IO::AIO::sendfile.
71 - (libeio) replaced quicksort+insertion sort by a tuned radix
72 sort + insertion sort, resulting in comparable runtime (usually
73 faster) to the old version, but without any ill side effects on
74 degenerated (for quicksort) data.
75 - (libeio) correctly sort dirs by inodes if we have perfect type
76 knowledge and DIRS_FIRST is used.
77 - (libeio) internally the wrong DT_* constants were used, but no
78 known system has differing EIO_DT_*/DT_* values, so not an issue.
79 - removed a (harmless) assert that was left over on the code
80 but should not have been.
81 - use more correct types (change IO length from IV to VAL64,
82 which makes a difference on systems without 64 bit perls).
83
843.23 Sat Jun 13 16:57:58 CEST 2009
85 - fix off-by-one bug in aio_readdir that was introduced in the
86 rushed 3.22 release.
87
883.22 Sat Jun 13 15:32:40 CEST 2009
89 - speed up readdirx sort algorithm slightly.
90 - bin/treescan was missing from distro tarball.
91
923.21 Fri Jun 12 18:45:53 CEST 2009
93 - new options --dirs and --files for treescan.
94 - install bin/treescan by default.
95 - (libeio) aio_readdir can now be cancelled while executing.
96 - fix a printf format string for 64 bit systems (could lead
97 to problems on big endian 64 bit systems).
98 - do not use qsort() but our own algorithm: glibc initialises
99 the whole locale and I/O subsystem inside qsort, causing
100 a stack overflow on 32 bit machines. The new sort uses much less
101 stack and is more than twice as fast in typical situations.
102
1033.2 Sun Jun 7 20:30:05 CEST 2009
104 - (libeio) pwrite emulation was even more flawed than intended and did
105 not restore the file offset.
106 - add aio_readdirx, which can return inode and filetype and sort
107 the names in various ways.
108 - unfortunately, utime, chmod, chown on an open file that has just
109 been written can easily block, which caused aio_copy to block the
110 process. no more!
111 - no longer rely on dst path in aio_copy when futime is available.
112
1133.19 Tue Apr 21 22:05:21 CEST 2009
114 - more perl 5.10 workarounds for aio_read and write.
115 - aio_write no longer modifies the sv (if possible).
116 - aio_read now works correctly with magic values.
117
1183.18 Sun Apr 19 21:17:32 CEST 2009
119 - better diagnostics when some aio_* functions get passed an illegal fh.
120 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
121
1223.17 Thu Nov 20 08:45:36 CET 2008
123 - (libeio) added aio_sync_file_range (untested).
124 - add aio_busy to @IO::AIO::AIO_REQ.
125
1263.16 Wed Oct 22 18:28:01 CEST 2008
127 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
128 part to improve portability to perl 5.8 (reported by szymon).
129
1303.15 Mon Oct 13 00:39:55 CEST 2008
131 - automatic removal of feeders was broken.
132 - (libeio) use a more robust method to detect whether a feeder
133 has added something to the group or not.
134
1353.1 Thu Oct 2 13:34:40 CEST 2008
136 - pre-deref the passed callback object, for increased speed
137 and decreased memory usage.
138 - call on_next_submit callback even for aio_group - impact unknown,
139 but seems more correct.
140 - $req->cb now returns the original callback.
141 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
142 requiring a thread switch.
143 - (libeio) status code of aio_futime and aio_utime was always passed 0.
144 - do some other ยต-optimisations.
145
1463.07 Sat Aug 2 16:06:13 CEST 2008
147 - do not include LIBS in autoconf tests.
148
1493.06 Tue Jul 15 12:41:32 CEST 2008
9 - move preadwritelock definition before it's first reference, 150 - move preadwritelock definition before it's first reference,
10 to make it compile again on broken platforms (they still exist). 151 to make it compile again on broken platforms (they still exist)
11 rreported by Rob Bloodgood. 152 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.

133.05 Thu Jun 19 23:23:52 CEST 2008 1543.05 Thu Jun 19 23:23:52 CEST 2008
14 - work around perl overriding readdir etc. with thread-unsafe 155 - work around perl overriding readdir etc. with thread-unsafe
15 (sic!) versions. 156 (sic!) versions.
