14TODO: treescan using extra fds 37
38 - add IO::AIO::pipe2 function.
39 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
40 constants.
41 - added support for O_TMPFILE and O_PATH constants.
42 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
43 consdtants, whether they can be sensibly used or not.
44 - use NO_INIT where applicable.
45 - update libecb.
46 - added stability canary support.

484.32 Wed Feb 11 20:32:11 CET 2015
49 - replace off_t by STRLEN where appropriate, should not result in
50 user-visible changes.
51 - update ecb.h for C11 compatibility.
52
534.31 Tue Jun 3 03:29:27 CEST 2014
54 - work around more 5.20 bugs. backwards compatibility my ass.
55
564.3 Fri Apr 11 06:22:38 CEST 2014
57 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
58 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
59 in 5.18. What's so attractive about giving a shit about backwards
60 compatibility - I will never understand.
61
624.2 Sat Jan 25 01:13:14 CET 2014
63 - aio_group could corrupt memory because it didn't restore
64 the stack after req_submit.
65 - be more careful on (e.g. permission) errors in bin/treescan.
66 - work around changes in ExtUtils::MakeMaker.
67 - (libeio) implement aio_realpath for win32.
68 - (xthread) work around compile time bugs in ptw32.
69 - added IO::AIO::pipesize.
70 - (libecb) insignificant update.
71
724.19 Sun Jan 6 12:47:26 CET 2013
73 - avoid endless loop in fiemap with some XFS files.
74 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
75 and call rename/rmdir instead of renameat/unlinkat.
76
774.18 Thu Oct 11 07:01:26 CEST 2012
78 - fix unintended xthread_create by intentionalising it :)
79
804.17 Thu Oct 11 05:19:47 CEST 2012
81 - rename aio_fallocate to aio_allocate, to match documentation.
82 - add list of linux fsid values to aio_statvfs docs.
83 - work around a bug in btrfs' FIEMAP ioctl implementation.
84 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
85 as per unix spec.
86
874.16 Tue Aug 14 05:39:03 CEST 2012
88 - aio_statvfs was wromgly marked for wd emulation, causing
89 it to malfunction for paths.
90 - fix a crash in aio_fiemap, when used on ranges without any
91 extents.
92 - work around linux kernel bug (at least in 3.2): kernel might
93 trash fiemap input arguments.
94 - work around linux kernel bug (at least in 3.2): kernel does not
95 set FIEMAP_EXTENT_LAST on last segment.
96 - work around linux kernel bug (at least in 3.2): kernel silently
97 truncates segment count if a file.
98 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
99 to quick overview.
100 - splice can corrupt data.
101 - (libeio) remove pread/pwrite emulation.
102 - do not grow mmaped scalars in aio_read.
103 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
104 - provide pread/pwrite for win32, making it link again on native win32.
105
1064.15 Tue Apr 10 06:59:00 CEST 2012
107 - always include linux/types.h for fiemap, for compatibility to
108 ancient systems (Paul Howarth).
109 - experimental support for IO::AIO::splice and ::tee (no aio_...).
110 - provide SEEK_HOLE and SEEK_DATA, if available.
111 - work around (again!) an immensely stupid bug in RHEL, defining
112 autoconf macros in linux system headers (analysed by Paul Howarth).
113
1144.14 Sat Apr 7 02:45:18 CEST 2012
115 - fix stat structure usage on windows, which caused bogus stat results.
116 - (libeio) make readahead emulation behave more like actual readahead by never failing.

118 - new request aio_fiemap.
119 - autogenerate the #ifdef/#define 0 blocks for symbols we export.

123 instead of -1.

21 - reduce the number of file descriptors in use at any one time 136 - reduce the number of file descriptors in use at any one time
22 in treescan, to avoid running out of them (and using too much ram). 137 in treescan, to avoid running out of them (and using too much ram).
23 - take advantage of working directoriy abstractions 138 - take advantage of working directoriy abstractions
