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::m(un)lockall support.
15 - clean up manpage.
16
173.5 Thu Jan 7 21:25:04 CET 2010
18 - (liebio) fix freebsd sendfile (Vanilla Hsu).
19 - (libeio) also fix darwin sendfile that suffered from a similar bug.
20 - add aio_statvfs as interface to statvfs/fstatvfs.
21 - work around buggy symlink() on cygwin in the testsuite.
22 - wtf. freebsd-8.0 actually passes the testsuite! I knew
23 they could implement fork and semaphores one day! cheers!
24
253.4 Sat Jan 2 15:13:04 CET 2010
26 - (libeio) max_poll_time was not properly converted to ticks.
27 - clarify cancel_subs description.
28 - IO::AIO::sendfile did not actually return the return value
29 from the sendfile call.
30 - implement aio_msync, aio_mtouch.
31 - (libeio) tentatively support darwin in sendfile.
32
333.31 Thu Nov 12 02:14:29 CET 2009
34 - fix result status documentation of aio_copy, aio_move.
35 - speed up object creation considerably by avoiding
36 hash lookups.
37
383.3 Wed Aug 5 13:52:58 CEST 2009
39 - use common::sense.
40 - use common schmorp.h header.
41 - allow integers (file descriptors) in addition to file handles.
42 - take advantage of linux' eventfd (but it seems slower on smp?).
43 - use poll not select on posix platforms.
44
453.261 Wed Jul 1 10:11:51 CEST 2009
46 - more 0S X workarounds (patch by Tokuhiro Matsuno).
47
483.26 Tue Jun 30 09:33:26 CEST 2009
49 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
50 try to work around this horribly broken OS in a somewhat hackish
51 way. might help other os's too.
52
533.25 Sat Jun 27 05:18:26 CEST 2009
54 - added IO::AIO::fadvise and IO::AIO::sendfile.
55 - (libeio) replaced quicksort+insertion sort by a tuned radix
56 sort + insertion sort, resulting in comparable runtime (usually
57 faster) to the old version, but without any ill side effects on
58 degenerated (for quicksort) data.
59 - (libeio) correctly sort dirs by inodes if we have perfect type
60 knowledge and DIRS_FIRST is used.
61 - (libeio) internally the wrong DT_* constants were used, but no
62 known system has differing EIO_DT_*/DT_* values, so not an issue.
63 - removed a (harmless) assert that was left over on the code
64 but should not have been.
65 - use more correct types (change IO length from IV to VAL64,
66 which makes a difference on systems without 64 bit perls).
67
683.23 Sat Jun 13 16:57:58 CEST 2009
69 - fix off-by-one bug in aio_readdir that was introduced in the
70 rushed 3.22 release.
71
723.22 Sat Jun 13 15:32:40 CEST 2009
73 - speed up readdirx sort algorithm slightly.
74 - bin/treescan was missing from distro tarball.
75
763.21 Fri Jun 12 18:45:53 CEST 2009
77 - new options --dirs and --files for treescan.
78 - install bin/treescan by default.
79 - (libeio) aio_readdir can now be cancelled while executing.
80 - fix a printf format string for 64 bit systems (could lead
81 to problems on big endian 64 bit systems).
82 - do not use qsort() but our own algorithm: glibc initialises
83 the whole locale and I/O subsystem inside qsort, causing
84 a stack overflow on 32 bit machines. The new sort uses much less
85 stack and is more than twice as fast in typical situations.
86
873.2 Sun Jun 7 20:30:05 CEST 2009
88 - (libeio) pwrite emulation was even more flawed than intended and did
89 not restore the file offset.
90 - add aio_readdirx, which can return inode and filetype and sort
91 the names in various ways.
92 - unfortunately, utime, chmod, chown on an open file that has just
93 been written can easily block, which caused aio_copy to block the
94 process. no more!
95 - no longer rely on dst path in aio_copy when futime is available.
96
973.19 Tue Apr 21 22:05:21 CEST 2009
98 - more perl 5.10 workarounds for aio_read and write.
99 - aio_write no longer modifies the sv (if possible).
100 - aio_read now works correctly with magic values.
101
1023.18 Sun Apr 19 21:17:32 CEST 2009
103 - better diagnostics when some aio_* functions get passed an illegal fh.
104 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
105
1063.17 Thu Nov 20 08:45:36 CET 2008
107 - (libeio) added aio_sync_file_range (untested).
108 - add aio_busy to @IO::AIO::AIO_REQ.
109
1103.16 Wed Oct 22 18:28:01 CEST 2008
111 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
112 part to improve portability to perl 5.8 (reported by szymon).
113
1143.15 Mon Oct 13 00:39:55 CEST 2008
115 - automatic removal of feeders was broken.
116 - (libeio) use a more robust method to detect whether a feeder
117 has added something to the group or not.
118
1193.1 Thu Oct 2 13:34:40 CEST 2008
120 - pre-deref the passed callback object, for increased speed
121 and decreased memory usage.
122 - call on_next_submit callback even for aio_group - impact unknown,
123 but seems more correct.
124 - $req->cb now returns the original callback.
125 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
126 requiring a thread switch.
127 - (libeio) status code of aio_futime and aio_utime was always passed 0.
128 - do some other ยต-optimisations.
129
1303.07 Sat Aug 2 16:06:13 CEST 2008
131 - do not include LIBS in autoconf tests.
132
1333.06 Tue Jul 15 12:41:32 CEST 2008
134 - move preadwritelock definition before it's first reference,
135 to make it compile again on broken platforms (they still exist)
136 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
137
1383.05 Thu Jun 19 23:23:52 CEST 2008
139 - work around perl overriding readdir etc. with thread-unsafe
140 (sic!) versions.
141
1423.04 Wed Jun 18 01:35:38 CEST 2008
143 - (libeio) fix eio_mknod, which confused it's arguments.
144 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
145 is stupid.
146 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
147 - (libeio) fix a bug that could potentially cause IO::AIO
148 not to get initialised properly.
149
1503.03 Thu May 29 05:33:30 CEST 2008
151 - (libeio) correctly call pthread_attr_destroy ().
152 - (libeio) work around broken bsd headers once more.
153 - reduce shared library size again by not including wrappers.
154 - max_outstanding could cause poll to enter a busy-waiting loop.
155 - document the new IO::AIO::poll_cb result value.
156
1573.02 Mon May 12 02:32:02 CEST 2008
9 - fix a memory leak on aio_readlink. 158 - fix a memory leak on aio_readlink.
10 - bring back working fchmod. 159 - bring back working fchmod.
160 - nop and busy now set result to 0.
161 - set errno to ENOMEM when allocation fails.
11 162
123.01 Sun May 11 03:07:03 CEST 2008 1633.01 Sun May 11 03:07:03 CEST 2008
13 - (libeio) make it compile on systems without readahead or readdir_r. 164 - (libeio) make it compile on systems without readahead or readdir_r.
14 - (libeio) improve configure check for readahead availability. 165 - (libeio) improve configure check for readahead availability.
15 - do not try to link against -lrt. 166 - do not try to link against -lrt.
