12 const_iv (O_ASYNC) 254.2 Sat Jan 25 01:13:14 CET 2014
13 const_iv (O_DIRECT) 26 - aio_group could corrupt memory because it didn't restore
14 const_iv (O_NOATIME) 27 the stack after req_submit.
28 - be more careful on (e.g. permission) errors in bin/treescan.
29 - work around changes in ExtUtils::MakeMaker.
30 - (libeio) implement aio_realpath for win32.
31 - (xthread) work around compile time bugs in ptw32.
32 - added IO::AIO::pipesize.
33 - (libecb) insignificant update.

16 const_iv (O_CLOEXEC) 354.19 Sun Jan 6 12:47:26 CET 2013
17 const_iv (O_NOCTTY) 36 - avoid endless loop in fiemap with some XFS files.
18 const_iv (O_NOFOLLOW) 37 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
19 const_iv (O_NONBLOCK) 38 and call rename/rmdir instead of renameat/unlinkat.

404.18 Thu Oct 11 07:01:26 CEST 2012
41 - fix unintended xthread_create by intentionalising it :)
42
434.17 Thu Oct 11 05:19:47 CEST 2012
44 - rename aio_fallocate to aio_allocate, to match documentation.
45 - add list of linux fsid values to aio_statvfs docs.
46 - work around a bug in btrfs' FIEMAP ioctl implementation.
47 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
48 as per unix spec.
49
504.16 Tue Aug 14 05:39:03 CEST 2012
51 - aio_statvfs was wromgly marked for wd emulation, causing
52 it to malfunction for paths.
53 - fix a crash in aio_fiemap, when used on ranges without any
54 extents.
55 - work around linux kernel bug (at least in 3.2): kernel might
56 trash fiemap input arguments.
57 - work around linux kernel bug (at least in 3.2): kernel does not
58 set FIEMAP_EXTENT_LAST on last segment.
59 - work around linux kernel bug (at least in 3.2): kernel silently
60 truncates segment count if a file.
61 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
62 to quick overview.
63 - splice can corrupt data.
64 - (libeio) remove pread/pwrite emulation.
65 - do not grow mmaped scalars in aio_read.
66 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
67 - provide pread/pwrite for win32, making it link again on native win32.
68
694.15 Tue Apr 10 06:59:00 CEST 2012
70 - always include linux/types.h for fiemap, for compatibility to
71 ancient systems (Paul Howarth).
72 - experimental support for IO::AIO::splice and ::tee (no aio_...).
73 - provide SEEK_HOLE and SEEK_DATA, if available.
74 - work around (again!) an immensely stupid bug in RHEL, defining
75 autoconf macros in linux system headers (analysed by Paul Howarth).
76
774.14 Sat Apr 7 02:45:18 CEST 2012
78 - fix stat structure usage on windows, which caused bogus stat results.
79 - (libeio) make readahead emulation behave more like actual readahead by never failing.
80 - new request aio_seek.
81 - new request aio_fiemap.
82 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
83
844.12 Fri Dec 30 08:51:25 CET 2011
85 - realpath would return a random value if the name was too long,
86 instead of -1.
87 - port to c89.
88
894.11 Mon Oct 10 00:24:11 CEST 2011
90 - libeio didn't compile on !linux (Paul Howarth).
91
924.1 Sun Oct 9 10:24:11 CEST 2011
93 - IO::AIO did access uninitialised memory on unsuccessful stats.
94 - (libeio) added syncfs syscall wrapper.
95 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
96 - (libeio) support multiple indepenent working directories.
97 - applied speling corrections by Nicholas Bamber.
98 - tune treescan #threads and #outstanding requests a bit.
99 - reduce the number of file descriptors in use at any one time
100 in treescan, to avoid running out of them (and using too much ram).
101 - take advantage of working directoriy abstractions
102 in aio_scandir and treescan.
103 - reduce compiled size by ~10% by not inlining some key functionality.
104 - added --progress switch to treescan.
105
1064.0 Mon Jul 18 05:01:10 CEST 2011
107 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
108 see FORK BEHAVIOUR in manpage for details.
109 - passes testsuite on win32 now and may actually work
110 (activestate 5.10.1 / MSVC6, YMMV).
111 - (libeio) fix a deadlock where a wakeup signal could be missed when
112 a timeout occured at the same time.
113 - (libeio) added realpath.
114 - (libeio) added fallocate.
115 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
116 - (libeio) do not acquire any locks when forking.
117 - (libeio) use fewer time() syscalls when waiting for new requests.
118
1193.93 Wed Jun 29 23:44:18 CEST 2011
120 - ECB.H WAS MISSING.
121
1223.92 Wed Jun 29 14:45:41 CEST 2011
123 - ecb.h was missing.
124
1253.91 Wed Jun 29 13:24:42 CEST 2011
126 - (libeio) work around a Linux (and likely FreeBSD and other
127 kernels) bug where sendfile would not transfer all the requested
128 bytes on large transfers, using a heuristic.
129 - buggy sendfile caused aio_move/copy to sometimes fail for big
130 files (fortunately it checks that the whole file has been
131 transferred...)
132 - use libecb for higher performance and higher portability.
133 - (libeio) disable sendfile on darwin, it's too broken.
134 - disable fork tests on !linux, as only linux supports mixing
135 pthread and fork in perl.
136 - document the fact that fork doesn't work anymore when using
137 this module, on anything !GNU/Linux.
138 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
139 run on a 0.1MHz cpu. Or so.
140
1413.9 Fri May 27 02:43:47 CEST 2011
142 - (libeio) fix memory corruption in aio_readdirx for the flags
143 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
144 - add lots of newer POSIX and GNU/Linux-specific open
145 flags.
28 146
293.8 Sun Mar 27 12:25:33 CEST 2011 1473.8 Sun Mar 27 12:25:33 CEST 2011
30 - use nonstandard but maybe-working-on-bsd fork technique. 148 - use nonstandard but maybe-working-on-bsd fork technique.
31 - support a max_idle value of 0. 149 - support a max_idle value of 0.
32 - support setting of idle timeout value (IO::AIO::idle_timeout). 150 - support setting of idle timeout value (IO::AIO::idle_timeout).
