8 12
13 - use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock.
14 - new treescan option: --grep.
15
163.71 Thu Dec 30 08:18:46 CET 2010
17 - the numerical result value passed to callbacks did not stringify
18 correctly, due to internal reuse and failure to reset the sv flags.
19 - actually test for posix_[mf]advise, as at least uClibc defines
20 _POSIX_ADVISORY_INFO without actually having any of the required
21 funcitonality. ugh.
22
233.7 Mon Nov 1 23:00:34 CET 2010
24 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
25 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
26 - document the sad state of affairs w.r.t. pthread on many bsds.
27 - do not enable mmap on systems without _POSIX_MAPPED_FILES
28 (openbsd 4.8).
29 - do not leak memory in IO::AIO::mmap when the scalar already
30 had string-data.
31 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
32 them.
33 - cache the result IV, for a minor speedup in the common case.
34 - croak when an mmapped-scalar changes location, to detect
35 user-errors better.
36 - fix aio_readlink prototype.
37
383.65 Wed Mar 31 02:45:05 CEST 2010
39 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
40 cut off long pathnames in aio_readlink (based on patch by
41 Rasmus Andersson).
42 - a double fork partially killed the event pipe (great testcase
43 by dormando). affects IO::AIO, BDB and Async::Interrupt.
44 - suck steve's dick and rename our symbols to avoid colliding
45 with nonstandard identifier spam on the broken os x pseudo-os.
46 affects IO::AIO and BDB.
47
483.6 Mon Jan 11 00:43:39 CET 2010
49 - (libeio) more fixes for the freebsd/apple sendfile - broken by
50 manpage standards, but apparently correct accoridng to actual
51 kernel sources.
52 - add IO::AIO::mmap/munmap support.
53 - add IO::AIO::m(un)lockall support.
54 - clean up manpage.
55
563.5 Thu Jan 7 21:25:04 CET 2010
57 - (liebio) fix freebsd sendfile (Vanilla Hsu).
58 - (libeio) also fix darwin sendfile that suffered from a similar bug.
59 - add aio_statvfs as interface to statvfs/fstatvfs.
60 - work around buggy symlink() on cygwin in the testsuite.
61 - wtf. freebsd-8.0 actually passes the testsuite! I knew
62 they could implement fork and semaphores one day! cheers!
63
643.4 Sat Jan 2 15:13:04 CET 2010
65 - (libeio) max_poll_time was not properly converted to ticks.
66 - clarify cancel_subs description.
67 - IO::AIO::sendfile did not actually return the return value
68 from the sendfile call.
69 - implement aio_msync, aio_mtouch.
70 - (libeio) tentatively support darwin in sendfile.
71
723.31 Thu Nov 12 02:14:29 CET 2009
73 - fix result status documentation of aio_copy, aio_move.
74 - speed up object creation considerably by avoiding
75 hash lookups.
76
773.3 Wed Aug 5 13:52:58 CEST 2009
78 - use common::sense.
79 - use common schmorp.h header.
80 - allow integers (file descriptors) in addition to file handles.
81 - take advantage of linux' eventfd (but it seems slower on smp?).
82 - use poll not select on posix platforms.
83
843.261 Wed Jul 1 10:11:51 CEST 2009
85 - more 0S X workarounds (patch by Tokuhiro Matsuno).
86
873.26 Tue Jun 30 09:33:26 CEST 2009
88 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
89 try to work around this horribly broken OS in a somewhat hackish
90 way. might help other os's too.
91
923.25 Sat Jun 27 05:18:26 CEST 2009
93 - added IO::AIO::fadvise and IO::AIO::sendfile.
94 - (libeio) replaced quicksort+insertion sort by a tuned radix
95 sort + insertion sort, resulting in comparable runtime (usually
96 faster) to the old version, but without any ill side effects on
97 degenerated (for quicksort) data.
98 - (libeio) correctly sort dirs by inodes if we have perfect type
99 knowledge and DIRS_FIRST is used.
100 - (libeio) internally the wrong DT_* constants were used, but no
101 known system has differing EIO_DT_*/DT_* values, so not an issue.
102 - removed a (harmless) assert that was left over on the code
103 but should not have been.
104 - use more correct types (change IO length from IV to VAL64,
105 which makes a difference on systems without 64 bit perls).
106
1073.23 Sat Jun 13 16:57:58 CEST 2009
108 - fix off-by-one bug in aio_readdir that was introduced in the
109 rushed 3.22 release.
110
1113.22 Sat Jun 13 15:32:40 CEST 2009
112 - speed up readdirx sort algorithm slightly.
113 - bin/treescan was missing from distro tarball.
114
1153.21 Fri Jun 12 18:45:53 CEST 2009
116 - new options --dirs and --files for treescan.
117 - install bin/treescan by default.
118 - (libeio) aio_readdir can now be cancelled while executing.
119 - fix a printf format string for 64 bit systems (could lead
120 to problems on big endian 64 bit systems).
121 - do not use qsort() but our own algorithm: glibc initialises
122 the whole locale and I/O subsystem inside qsort, causing
123 a stack overflow on 32 bit machines. The new sort uses much less
124 stack and is more than twice as fast in typical situations.
125
1263.2 Sun Jun 7 20:30:05 CEST 2009
127 - (libeio) pwrite emulation was even more flawed than intended and did
128 not restore the file offset.
129 - add aio_readdirx, which can return inode and filetype and sort
130 the names in various ways.
131 - unfortunately, utime, chmod, chown on an open file that has just
132 been written can easily block, which caused aio_copy to block the
133 process. no more!
134 - no longer rely on dst path in aio_copy when futime is available.
135
1363.19 Tue Apr 21 22:05:21 CEST 2009
137 - more perl 5.10 workarounds for aio_read and write.
138 - aio_write no longer modifies the sv (if possible).
139 - aio_read now works correctly with magic values.
140
1413.18 Sun Apr 19 21:17:32 CEST 2009
142 - better diagnostics when some aio_* functions get passed an illegal fh.
143 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
144
1453.17 Thu Nov 20 08:45:36 CET 2008
146 - (libeio) added aio_sync_file_range (untested).
147 - add aio_busy to @IO::AIO::AIO_REQ.
148
1493.16 Wed Oct 22 18:28:01 CEST 2008
150 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
151 part to improve portability to perl 5.8 (reported by szymon).
152
1533.15 Mon Oct 13 00:39:55 CEST 2008
154 - automatic removal of feeders was broken.
155 - (libeio) use a more robust method to detect whether a feeder
156 has added something to the group or not.
157
1583.1 Thu Oct 2 13:34:40 CEST 2008
159 - pre-deref the passed callback object, for increased speed
160 and decreased memory usage.
161 - call on_next_submit callback even for aio_group - impact unknown,
162 but seems more correct.
163 - $req->cb now returns the original callback.
164 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
165 requiring a thread switch.
166 - (libeio) status code of aio_futime and aio_utime was always passed 0.
167 - do some other ยต-optimisations.
168
1693.07 Sat Aug 2 16:06:13 CEST 2008
170 - do not include LIBS in autoconf tests.
171
1723.06 Tue Jul 15 12:41:32 CEST 2008
173 - move preadwritelock definition before it's first reference,
174 to make it compile again on broken platforms (they still exist)
175 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
176
1773.05 Thu Jun 19 23:23:52 CEST 2008
178 - work around perl overriding readdir etc. with thread-unsafe
179 (sic!) versions.
180
1813.04 Wed Jun 18 01:35:38 CEST 2008
182 - (libeio) fix eio_mknod, which confused it's arguments.
183 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
184 is stupid.
185 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
186 - (libeio) fix a bug that could potentially cause IO::AIO
187 not to get initialised properly.
188
1893.03 Thu May 29 05:33:30 CEST 2008
190 - (libeio) correctly call pthread_attr_destroy ().
191 - (libeio) work around broken bsd headers once more.
192 - reduce shared library size again by not including wrappers.
193 - max_outstanding could cause poll to enter a busy-waiting loop.
194 - document the new IO::AIO::poll_cb result value.
195
1963.02 Mon May 12 02:32:02 CEST 2008
197 - fix a memory leak on aio_readlink.
198 - bring back working fchmod.
199 - nop and busy now set result to 0.
200 - set errno to ENOMEM when allocation fails.
201
2023.01 Sun May 11 03:07:03 CEST 2008
203 - (libeio) make it compile on systems without readahead or readdir_r.
204 - (libeio) improve configure check for readahead availability.
205 - do not try to link against -lrt.
206 - use a separate configure script for IO::AIO (not the libeio one).
207
2083.0 Sun May 11 00:57:14 CEST 2008
209 - added bin/treescan to the distribution.
210 - switched to using libeio.
211 - LOTS OF INCOMPATIBLE CHANGES:
212 - remove signal functionality, it is not worth the effort.

9 - port to solaris perls configured for old posix 217 - port to solaris perls configured for old posix
10 (analysed by Jost Krieger). 218 (analysed by Jost Krieger).
219 - keep a reference to the perl filehandle object in aio_close,
220 so it doesn't get closed prematurely, leading to ugly races.
11 221
