93.0 11TODO: posix_madvise.
10 - lots of incompatible changes: 12TODO: OS X spams thread_t into the global namespace, and doesn't even document it.
13
14 - a double fork partially killed the event pipe (great testcase
15 by dormando). affects IO::AIO, BDB and Async::Interrupt.
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
203.6 Mon Jan 11 00:43:39 CET 2010
21 - (libeio) more fixes for the freebsd/apple sendfile - broken by
22 manpage standards, but apparently correct accoridng to actual
23 kernel sources.
24 - add IO::AIO::mmap/munmap support.
25 - add IO::AIO::m(un)lockall support.
26 - clean up manpage.
27
283.5 Thu Jan 7 21:25:04 CET 2010
29 - (liebio) fix freebsd sendfile (Vanilla Hsu).
30 - (libeio) also fix darwin sendfile that suffered from a similar bug.
31 - add aio_statvfs as interface to statvfs/fstatvfs.
32 - work around buggy symlink() on cygwin in the testsuite.
33 - wtf. freebsd-8.0 actually passes the testsuite! I knew
34 they could implement fork and semaphores one day! cheers!
35
363.4 Sat Jan 2 15:13:04 CET 2010
37 - (libeio) max_poll_time was not properly converted to ticks.
38 - clarify cancel_subs description.
39 - IO::AIO::sendfile did not actually return the return value
40 from the sendfile call.
41 - implement aio_msync, aio_mtouch.
42 - (libeio) tentatively support darwin in sendfile.
43
443.31 Thu Nov 12 02:14:29 CET 2009
45 - fix result status documentation of aio_copy, aio_move.
46 - speed up object creation considerably by avoiding
47 hash lookups.
48
493.3 Wed Aug 5 13:52:58 CEST 2009
50 - use common::sense.
51 - use common schmorp.h header.
52 - allow integers (file descriptors) in addition to file handles.
53 - take advantage of linux' eventfd (but it seems slower on smp?).
54 - use poll not select on posix platforms.
55
563.261 Wed Jul 1 10:11:51 CEST 2009
57 - more 0S X workarounds (patch by Tokuhiro Matsuno).
58
593.26 Tue Jun 30 09:33:26 CEST 2009
60 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
61 try to work around this horribly broken OS in a somewhat hackish
62 way. might help other os's too.
63
643.25 Sat Jun 27 05:18:26 CEST 2009
65 - added IO::AIO::fadvise and IO::AIO::sendfile.
66 - (libeio) replaced quicksort+insertion sort by a tuned radix
67 sort + insertion sort, resulting in comparable runtime (usually
68 faster) to the old version, but without any ill side effects on
69 degenerated (for quicksort) data.
70 - (libeio) correctly sort dirs by inodes if we have perfect type
71 knowledge and DIRS_FIRST is used.
72 - (libeio) internally the wrong DT_* constants were used, but no
73 known system has differing EIO_DT_*/DT_* values, so not an issue.
74 - removed a (harmless) assert that was left over on the code
75 but should not have been.
76 - use more correct types (change IO length from IV to VAL64,
77 which makes a difference on systems without 64 bit perls).
78
793.23 Sat Jun 13 16:57:58 CEST 2009
80 - fix off-by-one bug in aio_readdir that was introduced in the
81 rushed 3.22 release.
82
833.22 Sat Jun 13 15:32:40 CEST 2009
84 - speed up readdirx sort algorithm slightly.
85 - bin/treescan was missing from distro tarball.
86
873.21 Fri Jun 12 18:45:53 CEST 2009
88 - new options --dirs and --files for treescan.
89 - install bin/treescan by default.
90 - (libeio) aio_readdir can now be cancelled while executing.
91 - fix a printf format string for 64 bit systems (could lead
92 to problems on big endian 64 bit systems).
93 - do not use qsort() but our own algorithm: glibc initialises
94 the whole locale and I/O subsystem inside qsort, causing
95 a stack overflow on 32 bit machines. The new sort uses much less
96 stack and is more than twice as fast in typical situations.
97
983.2 Sun Jun 7 20:30:05 CEST 2009
99 - (libeio) pwrite emulation was even more flawed than intended and did
100 not restore the file offset.
101 - add aio_readdirx, which can return inode and filetype and sort
102 the names in various ways.
103 - unfortunately, utime, chmod, chown on an open file that has just
104 been written can easily block, which caused aio_copy to block the
105 process. no more!
106 - no longer rely on dst path in aio_copy when futime is available.
107
1083.19 Tue Apr 21 22:05:21 CEST 2009
109 - more perl 5.10 workarounds for aio_read and write.
110 - aio_write no longer modifies the sv (if possible).
111 - aio_read now works correctly with magic values.
112
1133.18 Sun Apr 19 21:17:32 CEST 2009
114 - better diagnostics when some aio_* functions get passed an illegal fh.
115 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
116
1173.17 Thu Nov 20 08:45:36 CET 2008
118 - (libeio) added aio_sync_file_range (untested).
119 - add aio_busy to @IO::AIO::AIO_REQ.
120
1213.16 Wed Oct 22 18:28:01 CEST 2008
122 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
123 part to improve portability to perl 5.8 (reported by szymon).
124
1253.15 Mon Oct 13 00:39:55 CEST 2008
126 - automatic removal of feeders was broken.
127 - (libeio) use a more robust method to detect whether a feeder
128 has added something to the group or not.
129
1303.1 Thu Oct 2 13:34:40 CEST 2008
131 - pre-deref the passed callback object, for increased speed
132 and decreased memory usage.
133 - call on_next_submit callback even for aio_group - impact unknown,
134 but seems more correct.
135 - $req->cb now returns the original callback.
136 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
137 requiring a thread switch.
138 - (libeio) status code of aio_futime and aio_utime was always passed 0.
139 - do some other ยต-optimisations.
140
1413.07 Sat Aug 2 16:06:13 CEST 2008
142 - do not include LIBS in autoconf tests.
143
1443.06 Tue Jul 15 12:41:32 CEST 2008
145 - move preadwritelock definition before it's first reference,
146 to make it compile again on broken platforms (they still exist)
147 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
148
1493.05 Thu Jun 19 23:23:52 CEST 2008
150 - work around perl overriding readdir etc. with thread-unsafe
151 (sic!) versions.
152
1533.04 Wed Jun 18 01:35:38 CEST 2008
154 - (libeio) fix eio_mknod, which confused it's arguments.
155 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
156 is stupid.
157 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
158 - (libeio) fix a bug that could potentially cause IO::AIO
159 not to get initialised properly.
160
1613.03 Thu May 29 05:33:30 CEST 2008
162 - (libeio) correctly call pthread_attr_destroy ().
163 - (libeio) work around broken bsd headers once more.
164 - reduce shared library size again by not including wrappers.
165 - max_outstanding could cause poll to enter a busy-waiting loop.
166 - document the new IO::AIO::poll_cb result value.
167
1683.02 Mon May 12 02:32:02 CEST 2008
169 - fix a memory leak on aio_readlink.
170 - bring back working fchmod.
171 - nop and busy now set result to 0.
172 - set errno to ENOMEM when allocation fails.
173
1743.01 Sun May 11 03:07:03 CEST 2008
175 - (libeio) make it compile on systems without readahead or readdir_r.
176 - (libeio) improve configure check for readahead availability.
177 - do not try to link against -lrt.
178 - use a separate configure script for IO::AIO (not the libeio one).
179
1803.0 Sun May 11 00:57:14 CEST 2008
181 - added bin/treescan to the distribution.
182 - switched to using libeio.
183 - LOTS OF INCOMPATIBLE CHANGES:
11 - remove signal functionality, it is not worth the effort. 184 - remove signal functionality, it is not worth the effort.
12 - max_outstanding no longer returns the previous number of requests. 185 - max_outstanding no longer returns the previous number of requests.
