113.9 Fri May 27 02:43:47 CEST 2011
12 - (libeio) fix memory corruption in aio_readdirx for the flags
13 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
14 - add lots of newre POSIX and GNU/Linux-specific open
15 flags.
16
173.8 Sun Mar 27 12:25:33 CEST 2011
18 - use nonstandard but maybe-working-on-bsd fork technique.
19 - support a max_idle value of 0.
20 - support setting of idle timeout value (IO::AIO::idle_timeout).
21
223.72 Fri Feb 11 04:25:38 CET 2011
23 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
24 - aio_mknod always used a dev_t value of 0.
25 - new treescan option: --grep.
26 - add more S_IF macros, and major/minor/makedev "macros".
27
283.71 Thu Dec 30 08:18:46 CET 2010
29 - the numerical result value passed to callbacks did not stringify
30 correctly, due to internal reuse and failure to reset the sv flags.
31 - actually test for posix_[mf]advise, as at least uClibc defines
32 _POSIX_ADVISORY_INFO without actually having any of the required
33 funcitonality. ugh.
34
353.7 Mon Nov 1 23:00:34 CET 2010
36 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
37 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
38 - document the sad state of affairs w.r.t. pthread on many bsds.
39 - do not enable mmap on systems without _POSIX_MAPPED_FILES
40 (openbsd 4.8).
41 - do not leak memory in IO::AIO::mmap when the scalar already
42 had string-data.
43 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
44 them.
45 - cache the result IV, for a minor speedup in the common case.
46 - croak when an mmapped-scalar changes location, to detect
47 user-errors better.
48 - fix aio_readlink prototype.
49
503.65 Wed Mar 31 02:45:05 CEST 2010
51 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
52 cut off long pathnames in aio_readlink (based on patch by
53 Rasmus Andersson).
54 - a double fork partially killed the event pipe (great testcase
55 by dormando). affects IO::AIO, BDB and Async::Interrupt.
56 - suck steve's dick and rename our symbols to avoid colliding
57 with nonstandard identifier spam on the broken os x pseudo-os.
58 affects IO::AIO and BDB.
59
603.6 Mon Jan 11 00:43:39 CET 2010
61 - (libeio) more fixes for the freebsd/apple sendfile - broken by
62 manpage standards, but apparently correct accoridng to actual
63 kernel sources.
64 - add IO::AIO::mmap/munmap support.
65 - add IO::AIO::m(un)lockall support.
66 - clean up manpage.
67
683.5 Thu Jan 7 21:25:04 CET 2010
69 - (liebio) fix freebsd sendfile (Vanilla Hsu).
70 - (libeio) also fix darwin sendfile that suffered from a similar bug.
71 - add aio_statvfs as interface to statvfs/fstatvfs.
72 - work around buggy symlink() on cygwin in the testsuite.
73 - wtf. freebsd-8.0 actually passes the testsuite! I knew
74 they could implement fork and semaphores one day! cheers!
75
763.4 Sat Jan 2 15:13:04 CET 2010
77 - (libeio) max_poll_time was not properly converted to ticks.
78 - clarify cancel_subs description.
79 - IO::AIO::sendfile did not actually return the return value
80 from the sendfile call.
81 - implement aio_msync, aio_mtouch.
82 - (libeio) tentatively support darwin in sendfile.
83
843.31 Thu Nov 12 02:14:29 CET 2009
85 - fix result status documentation of aio_copy, aio_move.
86 - speed up object creation considerably by avoiding
87 hash lookups.
88
893.3 Wed Aug 5 13:52:58 CEST 2009
90 - use common::sense.
91 - use common schmorp.h header.
92 - allow integers (file descriptors) in addition to file handles.
93 - take advantage of linux' eventfd (but it seems slower on smp?).
94 - use poll not select on posix platforms.
95
963.261 Wed Jul 1 10:11:51 CEST 2009
97 - more 0S X workarounds (patch by Tokuhiro Matsuno).
98
993.26 Tue Jun 30 09:33:26 CEST 2009
100 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
101 try to work around this horribly broken OS in a somewhat hackish
102 way. might help other os's too.
103
1043.25 Sat Jun 27 05:18:26 CEST 2009
105 - added IO::AIO::fadvise and IO::AIO::sendfile.
106 - (libeio) replaced quicksort+insertion sort by a tuned radix
107 sort + insertion sort, resulting in comparable runtime (usually
108 faster) to the old version, but without any ill side effects on
109 degenerated (for quicksort) data.
110 - (libeio) correctly sort dirs by inodes if we have perfect type
111 knowledge and DIRS_FIRST is used.
112 - (libeio) internally the wrong DT_* constants were used, but no
113 known system has differing EIO_DT_*/DT_* values, so not an issue.
114 - removed a (harmless) assert that was left over on the code
115 but should not have been.
116 - use more correct types (change IO length from IV to VAL64,
117 which makes a difference on systems without 64 bit perls).
118
1193.23 Sat Jun 13 16:57:58 CEST 2009
120 - fix off-by-one bug in aio_readdir that was introduced in the
121 rushed 3.22 release.
122
1233.22 Sat Jun 13 15:32:40 CEST 2009
124 - speed up readdirx sort algorithm slightly.
125 - bin/treescan was missing from distro tarball.
126
1273.21 Fri Jun 12 18:45:53 CEST 2009
128 - new options --dirs and --files for treescan.
129 - install bin/treescan by default.
130 - (libeio) aio_readdir can now be cancelled while executing.
131 - fix a printf format string for 64 bit systems (could lead
132 to problems on big endian 64 bit systems).
133 - do not use qsort() but our own algorithm: glibc initialises
134 the whole locale and I/O subsystem inside qsort, causing
135 a stack overflow on 32 bit machines. The new sort uses much less
136 stack and is more than twice as fast in typical situations.
137
1383.2 Sun Jun 7 20:30:05 CEST 2009
139 - (libeio) pwrite emulation was even more flawed than intended and did
140 not restore the file offset.
141 - add aio_readdirx, which can return inode and filetype and sort
142 the names in various ways.
143 - unfortunately, utime, chmod, chown on an open file that has just
144 been written can easily block, which caused aio_copy to block the
145 process. no more!
146 - no longer rely on dst path in aio_copy when futime is available.
147
1483.19 Tue Apr 21 22:05:21 CEST 2009
149 - more perl 5.10 workarounds for aio_read and write.
150 - aio_write no longer modifies the sv (if possible).
151 - aio_read now works correctly with magic values.
152
1533.18 Sun Apr 19 21:17:32 CEST 2009
154 - better diagnostics when some aio_* functions get passed an illegal fh.
155 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
156
1573.17 Thu Nov 20 08:45:36 CET 2008
158 - (libeio) added aio_sync_file_range (untested).
159 - add aio_busy to @IO::AIO::AIO_REQ.
160
1613.16 Wed Oct 22 18:28:01 CEST 2008
162 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
163 part to improve portability to perl 5.8 (reported by szymon).
164
1653.15 Mon Oct 13 00:39:55 CEST 2008
166 - automatic removal of feeders was broken.
167 - (libeio) use a more robust method to detect whether a feeder
168 has added something to the group or not.
169
1703.1 Thu Oct 2 13:34:40 CEST 2008
171 - pre-deref the passed callback object, for increased speed
172 and decreased memory usage.
173 - call on_next_submit callback even for aio_group - impact unknown,
174 but seems more correct.
175 - $req->cb now returns the original callback.
176 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
177 requiring a thread switch.
178 - (libeio) status code of aio_futime and aio_utime was always passed 0.
179 - do some other ยต-optimisations.
180
1813.07 Sat Aug 2 16:06:13 CEST 2008
182 - do not include LIBS in autoconf tests.
183
1843.06 Tue Jul 15 12:41:32 CEST 2008
185 - move preadwritelock definition before it's first reference,
186 to make it compile again on broken platforms (they still exist)
187 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.

93.05 Thu Jun 19 23:23:52 CEST 2008 1893.05 Thu Jun 19 23:23:52 CEST 2008
