39TODO: aio_fcntl/ioctl test.
40
41 - removed duplicate definition of MAP_HUGETLB, that was found due to
42 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
43 - added (untested!) aio_fcntl, aio_ioctl requests.
44
454.33 Mon Jan 18 12:50:10 CET 2016
46 - add IO::AIO::pipe2 function.
47 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
48 constants.
49 - added support for O_TMPFILE and O_PATH constants.
50 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
51 consdtants, whether they can be sensibly used or not.
52 - use NO_INIT where applicable.
53 - update libecb.
54 - added stability canary support.

56
574.32 Wed Feb 11 20:32:11 CET 2015
58 - replace off_t by STRLEN where appropriate, should not result in
59 user-visible changes.

61
624.31 Tue Jun 3 03:29:27 CEST 2014
63 - work around more 5.20 bugs. backwards compatibility my ass.
64
654.3 Fri Apr 11 06:22:38 CEST 2014
66 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
67 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
68 in 5.18. What's so attractive about giving a shit about backwards
69 compatibility - I will never understand.
70
714.2 Sat Jan 25 01:13:14 CET 2014
72 - aio_group could corrupt memory because it didn't restore
73 the stack after req_submit.
74 - be more careful on (e.g. permission) errors in bin/treescan.
75 - work around changes in ExtUtils::MakeMaker.
76 - (libeio) implement aio_realpath for win32.
77 - (xthread) work around compile time bugs in ptw32.
78 - added IO::AIO::pipesize.
79 - (libecb) insignificant update.
80
814.19 Sun Jan 6 12:47:26 CET 2013
82 - avoid endless loop in fiemap with some XFS files.
83 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
84 and call rename/rmdir instead of renameat/unlinkat.
85
864.18 Thu Oct 11 07:01:26 CEST 2012
87 - fix unintended xthread_create by intentionalising it :)
88
894.17 Thu Oct 11 05:19:47 CEST 2012
90 - rename aio_fallocate to aio_allocate, to match documentation.
91 - add list of linux fsid values to aio_statvfs docs.
92 - work around a bug in btrfs' FIEMAP ioctl implementation.
93 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
94 as per unix spec.
95
964.16 Tue Aug 14 05:39:03 CEST 2012
97 - aio_statvfs was wromgly marked for wd emulation, causing
98 it to malfunction for paths.
99 - fix a crash in aio_fiemap, when used on ranges without any
100 extents.
101 - work around linux kernel bug (at least in 3.2): kernel might
102 trash fiemap input arguments.
103 - work around linux kernel bug (at least in 3.2): kernel does not
104 set FIEMAP_EXTENT_LAST on last segment.
105 - work around linux kernel bug (at least in 3.2): kernel silently
106 truncates segment count if a file.
107 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
108 to quick overview.
109 - splice can corrupt data.
110 - (libeio) remove pread/pwrite emulation.
111 - do not grow mmaped scalars in aio_read.
112 - add FALLOC_FL_PUNCH_HOLE and document fallocate.

114
1154.15 Tue Apr 10 06:59:00 CEST 2012
116 - always include linux/types.h for fiemap, for compatibility to
117 ancient systems (Paul Howarth).
118 - experimental support for IO::AIO::splice and ::tee (no aio_...).
119 - provide SEEK_HOLE and SEEK_DATA, if available.
120 - work around (again!) an immensely stupid bug in RHEL, defining
121 autoconf macros in linux system headers (analysed by Paul Howarth).
122
1234.14 Sat Apr 7 02:45:18 CEST 2012
124 - fix stat structure usage on windows, which caused bogus stat results.

142 - (libeio) support multiple indepenent working directories.
143 - applied speling corrections by Nicholas Bamber.
144 - tune treescan #threads and #outstanding requests a bit.
145 - reduce the number of file descriptors in use at any one time
146 in treescan, to avoid running out of them (and using too much ram).
147 - take advantage of working directoriy abstractions
148 in aio_scandir and treescan.
149 - reduce compiled size by ~10% by not inlining some key functionality.
150 - added --progress switch to treescan.
151
1524.0 Mon Jul 18 05:01:10 CEST 2011
153 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
154 see FORK BEHAVIOUR in manpage for details.
155 - passes testsuite on win32 now and may actually work
156 (activestate 5.10.1 / MSVC6, YMMV).

158 a timeout occured at the same time.
16 - (libeio) added realpath. 159 - (libeio) added realpath.
