14TODO: remove fork support, eio_init can be called multiple times maybe 13 - rename aio_fallocate to aio_allocate, to match documentation.
15TODO: "this might change" 14 - add list of linux fsid values to aio_statvfs docs.
15 - work around a bug in btrfs' FIEMAP ioctl implementation.
16
174.16 Tue Aug 14 05:39:03 CEST 2012
18 - aio_statvfs was wromgly marked for wd emulation, causing
19 it to malfunctiobn for paths.
20 - fix a crash in aio_fiemap, when used on ranges without any
21 extents.
22 - work around linux kernel bug (at least in 3.2): kernel might
23 trash fiemap input arguments.
24 - work around linux kernel bug (at least in 3.2): kernel does not
25 set FIEMAP_EXTENT_LAST on last segment.
26 - work around linux kernel bug (at least in 3.2): kernel silently
27 truncates segment count if a file.
28 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
29 to quick overview.
30 - splice can corrupt data.
31 - (libeio) remove pread/pwrite emulation.
32 - do not grow mmaped scalars in aio_read.
33 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
34 - provide pread/pwrite for win32, making it link again on native win32.
35
364.15 Tue Apr 10 06:59:00 CEST 2012
37 - always include linux/types.h for fiemap, for compatibility to
38 ancient systems (Paul Howarth).
39 - experimental support for IO::AIO::splice and ::tee (no aio_...).
40 - provide SEEK_HOLE and SEEK_DATA, if available.
41 - work around (again!) an immensely stupid bug in RHEL, defining
42 autoconf macros in linux system headers (analysed by Paul Howarth).
43
444.14 Sat Apr 7 02:45:18 CEST 2012
45 - fix stat structure usage on windows, which caused bogus stat results.
46 - (libeio) make readahead emulation behave more like actual readahead by never failing.
47 - new request aio_seek.
48 - new request aio_fiemap.
49 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
50
514.12 Fri Dec 30 08:51:25 CET 2011
52 - realpath would return a random value if the name was too long,
53 instead of -1.
54 - port to c89.
55
564.11 Mon Oct 10 00:24:11 CEST 2011
57 - libeio didn't compile on !linux (Paul Howarth).
58
594.1 Sun Oct 9 10:24:11 CEST 2011
60 - IO::AIO did access uninitialised memory on unsuccessful stats.
61 - (libeio) added syncfs syscall wrapper.
62 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
63 - (libeio) support multiple indepenent working directories.
64 - applied speling corrections by Nicholas Bamber.
65 - tune treescan #threads and #outstanding requests a bit.
66 - reduce the number of file descriptors in use at any one time
67 in treescan, to avoid running out of them (and using too much ram).
68 - take advantage of working directoriy abstractions
69 in aio_scandir and treescan.
70 - reduce compiled size by ~10% by not inlining some key functionality.
71 - added --progress switch to treescan.
72
734.0 Mon Jul 18 05:01:10 CEST 2011
74 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
75 see FORK BEHAVIOUR in manpage for details.
76 - passes testsuite on win32 now and may actually work
77 (activestate 5.10.1 / MSVC6, YMMV).
78 - (libeio) fix a deadlock where a wakeup signal could be missed when
79 a timeout occured at the same time.
16 - (libeio) added realpath. 80 - (libeio) added realpath.
17 - (libeio) added fallocate. 81 - (libeio) added fallocate.
18 - (libeio) disabling sendfile on darwin unfortunately broke the emulation. 82 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
83 - (libeio) do not acquire any locks when forking.
84 - (libeio) use fewer time() syscalls when waiting for new requests.
