8 9
93.0 10 - (libeio) max_poll_time was not properly converted to ticks.
10 - lots of incompatible changes: 11 - clarify cancel_subs description.
12
133.31 Thu Nov 12 02:14:29 CET 2009
14 - fix result status documentation of aio_copy, aio_move.
15 - speed up object creation considerably by avoiding
16 hash lookups.
17
183.3 Wed Aug 5 13:52:58 CEST 2009
19 - use common::sense.
20 - use common schmorp.h header.
21 - allow integers (file descriptors) in addition to file handles.
22 - take advantage of linux' eventfd (but it seems slower on smp?).
23 - use poll not select on posix platforms.
24
253.261 Wed Jul 1 10:11:51 CEST 2009
26 - more 0S X workarounds (patch by Tokuhiro Matsuno).
27
283.26 Tue Jun 30 09:33:26 CEST 2009
29 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
30 try to work around this horribly broken OS in a somewhat hackish
31 way. might help other os's too.
32
333.25 Sat Jun 27 05:18:26 CEST 2009
34 - added IO::AIO::fadvise and IO::AIO::sendfile.
35 - (libeio) replaced quicksort+insertion sort by a tuned radix
36 sort + insertion sort, resulting in comparable runtime (usually
37 faster) to the old version, but without any ill side effects on
38 degenerated (for quicksort) data.
39 - (libeio) correctly sort dirs by inodes if we have perfect type
40 knowledge and DIRS_FIRST is used.
41 - (libeio) internally the wrong DT_* constants were used, but no
42 known system has differing EIO_DT_*/DT_* values, so not an issue.
43 - removed a (harmless) assert that was left over on the code
44 but should not have been.
45 - use more correct types (change IO length from IV to VAL64,
46 which makes a difference on systems without 64 bit perls).
47
483.23 Sat Jun 13 16:57:58 CEST 2009
49 - fix off-by-one bug in aio_readdir that was introduced in the
50 rushed 3.22 release.
51
523.22 Sat Jun 13 15:32:40 CEST 2009
53 - speed up readdirx sort algorithm slightly.
54 - bin/treescan was missing from distro tarball.
55
563.21 Fri Jun 12 18:45:53 CEST 2009
57 - new options --dirs and --files for treescan.
58 - install bin/treescan by default.
59 - (libeio) aio_readdir can now be cancelled while executing.
60 - fix a printf format string for 64 bit systems (could lead
61 to problems on big endian 64 bit systems).
62 - do not use qsort() but our own algorithm: glibc initialises
63 the whole locale and I/O subsystem inside qsort, causing
64 a stack overflow on 32 bit machines. The new sort uses much less
65 stack and is more than twice as fast in typical situations.
66
673.2 Sun Jun 7 20:30:05 CEST 2009
68 - (libeio) pwrite emulation was even more flawed than intended and did
69 not restore the file offset.
70 - add aio_readdirx, which can return inode and filetype and sort
71 the names in various ways.
72 - unfortunately, utime, chmod, chown on an open file that has just
73 been written can easily block, which caused aio_copy to block the
74 process. no more!
75 - no longer rely on dst path in aio_copy when futime is available.
76
773.19 Tue Apr 21 22:05:21 CEST 2009
78 - more perl 5.10 workarounds for aio_read and write.
79 - aio_write no longer modifies the sv (if possible).
80 - aio_read now works correctly with magic values.
81
823.18 Sun Apr 19 21:17:32 CEST 2009
83 - better diagnostics when some aio_* functions get passed an illegal fh.
84 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
85
863.17 Thu Nov 20 08:45:36 CET 2008
87 - (libeio) added aio_sync_file_range (untested).
88 - add aio_busy to @IO::AIO::AIO_REQ.
89
903.16 Wed Oct 22 18:28:01 CEST 2008
91 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
92 part to improve portability to perl 5.8 (reported by szymon).
93
943.15 Mon Oct 13 00:39:55 CEST 2008
95 - automatic removal of feeders was broken.
96 - (libeio) use a more robust method to detect whether a feeder
97 has added something to the group or not.
98
993.1 Thu Oct 2 13:34:40 CEST 2008
100 - pre-deref the passed callback object, for increased speed
101 and decreased memory usage.
102 - call on_next_submit callback even for aio_group - impact unknown,
103 but seems more correct.
104 - $req->cb now returns the original callback.
105 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
106 requiring a thread switch.
107 - (libeio) status code of aio_futime and aio_utime was always passed 0.
108 - do some other ยต-optimisations.
109
1103.07 Sat Aug 2 16:06:13 CEST 2008
111 - do not include LIBS in autoconf tests.
112
1133.06 Tue Jul 15 12:41:32 CEST 2008
114 - move preadwritelock definition before it's first reference,
115 to make it compile again on broken platforms (they still exist)
116 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
117
1183.05 Thu Jun 19 23:23:52 CEST 2008
119 - work around perl overriding readdir etc. with thread-unsafe
120 (sic!) versions.
121
1223.04 Wed Jun 18 01:35:38 CEST 2008
123 - (libeio) fix eio_mknod, which confused it's arguments.
124 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
125 is stupid.
126 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
127 - (libeio) fix a bug that could potentially cause IO::AIO
128 not to get initialised properly.
129
1303.03 Thu May 29 05:33:30 CEST 2008
131 - (libeio) correctly call pthread_attr_destroy ().
132 - (libeio) work around broken bsd headers once more.
133 - reduce shared library size again by not including wrappers.
134 - max_outstanding could cause poll to enter a busy-waiting loop.
135 - document the new IO::AIO::poll_cb result value.
136
1373.02 Mon May 12 02:32:02 CEST 2008
138 - fix a memory leak on aio_readlink.
139 - bring back working fchmod.
140 - nop and busy now set result to 0.
141 - set errno to ENOMEM when allocation fails.
142
1433.01 Sun May 11 03:07:03 CEST 2008
144 - (libeio) make it compile on systems without readahead or readdir_r.
145 - (libeio) improve configure check for readahead availability.
146 - do not try to link against -lrt.
147 - use a separate configure script for IO::AIO (not the libeio one).
148
1493.0 Sun May 11 00:57:14 CEST 2008
150 - added bin/treescan to the distribution.
151 - switched to using libeio.
152 - LOTS OF INCOMPATIBLE CHANGES:
11 - remove signal functionality, it is not worth the effort. 153 - remove signal functionality, it is not worth the effort.
12 - max_outstanding no longer returns the previous number of requests. 154 - max_outstanding no longer returns the previous number of requests.
13 - poll_cb no longer returns number of requests. 155 - poll_cb no longer returns number of requests.
