11 - (libeio) more fixes for the freebsd/apple sendfile - broken by
12 manpage standards, but apparently correct accoridng to actual
13 kernel sources.
14 - add IO::AIO::mmap/munmap support.
15 - add IO::AIO::m(un)lockall support.
16 - clean up manpage.
17
183.5 Thu Jan 7 21:25:04 CET 2010
19 - (liebio) fix freebsd sendfile (Vanilla Hsu).
20 - (libeio) also fix darwin sendfile that suffered from a similar bug.
21 - add aio_statvfs as interface to statvfs/fstatvfs.
22 - work around buggy symlink() on cygwin in the testsuite.
23 - wtf. freebsd-8.0 actually passes the testsuite! I knew
24 they could implement fork and semaphores one day! cheers!
25
263.4 Sat Jan 2 15:13:04 CET 2010
27 - (libeio) max_poll_time was not properly converted to ticks.
28 - clarify cancel_subs description.
29 - IO::AIO::sendfile did not actually return the return value
30 from the sendfile call.
31 - implement aio_msync, aio_mtouch.
32 - (libeio) tentatively support darwin in sendfile.
33
343.31 Thu Nov 12 02:14:29 CET 2009
35 - fix result status documentation of aio_copy, aio_move.
36 - speed up object creation considerably by avoiding
37 hash lookups.
38
393.3 Wed Aug 5 13:52:58 CEST 2009
40 - use common::sense.
41 - use common schmorp.h header.
42 - allow integers (file descriptors) in addition to file handles.
43 - take advantage of linux' eventfd (but it seems slower on smp?).
44 - use poll not select on posix platforms.
45
463.261 Wed Jul 1 10:11:51 CEST 2009
47 - more 0S X workarounds (patch by Tokuhiro Matsuno).
48
493.26 Tue Jun 30 09:33:26 CEST 2009
50 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
51 try to work around this horribly broken OS in a somewhat hackish
52 way. might help other os's too.
53
543.25 Sat Jun 27 05:18:26 CEST 2009
55 - added IO::AIO::fadvise and IO::AIO::sendfile.
56 - (libeio) replaced quicksort+insertion sort by a tuned radix
57 sort + insertion sort, resulting in comparable runtime (usually
58 faster) to the old version, but without any ill side effects on
59 degenerated (for quicksort) data.
60 - (libeio) correctly sort dirs by inodes if we have perfect type
61 knowledge and DIRS_FIRST is used.
62 - (libeio) internally the wrong DT_* constants were used, but no
63 known system has differing EIO_DT_*/DT_* values, so not an issue.
64 - removed a (harmless) assert that was left over on the code
65 but should not have been.
66 - use more correct types (change IO length from IV to VAL64,
67 which makes a difference on systems without 64 bit perls).
68
693.23 Sat Jun 13 16:57:58 CEST 2009
70 - fix off-by-one bug in aio_readdir that was introduced in the
71 rushed 3.22 release.
72
733.22 Sat Jun 13 15:32:40 CEST 2009
74 - speed up readdirx sort algorithm slightly.
75 - bin/treescan was missing from distro tarball.
76
773.21 Fri Jun 12 18:45:53 CEST 2009
78 - new options --dirs and --files for treescan.
79 - install bin/treescan by default.
80 - (libeio) aio_readdir can now be cancelled while executing.
81 - fix a printf format string for 64 bit systems (could lead
82 to problems on big endian 64 bit systems).
83 - do not use qsort() but our own algorithm: glibc initialises
84 the whole locale and I/O subsystem inside qsort, causing
85 a stack overflow on 32 bit machines. The new sort uses much less
86 stack and is more than twice as fast in typical situations.
87
883.2 Sun Jun 7 20:30:05 CEST 2009
89 - (libeio) pwrite emulation was even more flawed than intended and did
90 not restore the file offset.
91 - add aio_readdirx, which can return inode and filetype and sort
92 the names in various ways.
93 - unfortunately, utime, chmod, chown on an open file that has just
94 been written can easily block, which caused aio_copy to block the
95 process. no more!
96 - no longer rely on dst path in aio_copy when futime is available.
97
983.19 Tue Apr 21 22:05:21 CEST 2009
99 - more perl 5.10 workarounds for aio_read and write.
100 - aio_write no longer modifies the sv (if possible).
101 - aio_read now works correctly with magic values.
102
1033.18 Sun Apr 19 21:17:32 CEST 2009
104 - better diagnostics when some aio_* functions get passed an illegal fh.
105 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
106
1073.17 Thu Nov 20 08:45:36 CET 2008
108 - (libeio) added aio_sync_file_range (untested).
109 - add aio_busy to @IO::AIO::AIO_REQ.
110
1113.16 Wed Oct 22 18:28:01 CEST 2008
112 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
113 part to improve portability to perl 5.8 (reported by szymon).
114
1153.15 Mon Oct 13 00:39:55 CEST 2008
116 - automatic removal of feeders was broken.
117 - (libeio) use a more robust method to detect whether a feeder
118 has added something to the group or not.
119
1203.1 Thu Oct 2 13:34:40 CEST 2008
121 - pre-deref the passed callback object, for increased speed
122 and decreased memory usage.
123 - call on_next_submit callback even for aio_group - impact unknown,
124 but seems more correct.
125 - $req->cb now returns the original callback.
126 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
127 requiring a thread switch.
128 - (libeio) status code of aio_futime and aio_utime was always passed 0.
129 - do some other ยต-optimisations.
130
1313.07 Sat Aug 2 16:06:13 CEST 2008
132 - do not include LIBS in autoconf tests.
133
1343.06 Tue Jul 15 12:41:32 CEST 2008
135 - move preadwritelock definition before it's first reference,
136 to make it compile again on broken platforms (they still exist)
137 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
138
1393.05 Thu Jun 19 23:23:52 CEST 2008
140 - work around perl overriding readdir etc. with thread-unsafe
141 (sic!) versions.
142
1433.04 Wed Jun 18 01:35:38 CEST 2008
144 - (libeio) fix eio_mknod, which confused it's arguments.
145 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
146 is stupid.
147 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
148 - (libeio) fix a bug that could potentially cause IO::AIO
149 not to get initialised properly.
150
1513.03 Thu May 29 05:33:30 CEST 2008
9 - (libeio) correctly call pthread_attr_destroy (). 152 - (libeio) correctly call pthread_attr_destroy ().
153 - (libeio) work around broken bsd headers once more.
154 - reduce shared library size again by not including wrappers.
155 - max_outstanding could cause poll to enter a busy-waiting loop.
156 - document the new IO::AIO::poll_cb result value.
10 157
113.02 Mon May 12 02:32:02 CEST 2008 1583.02 Mon May 12 02:32:02 CEST 2008
12 - fix a memory leak on aio_readlink. 159 - fix a memory leak on aio_readlink.
13 - bring back working fchmod. 160 - bring back working fchmod.
14 - nop and busy now set result to 0. 161 - nop and busy now set result to 0.
