11TODO: MS_xxx, posix_fadvise 12 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
13 to quick overview.
14 - splice can corrupt data.
15 - (libeio) remove pread/pwrite emulation.
16
174.15 Tue Apr 10 06:59:00 CEST 2012
18 - always include linux/types.h for fiemap, for compatibility to
19 ancient systems (Paul Howarth).
20 - experimental support for IO::AIO::splice and ::tee (no aio_...).
21 - provide SEEK_HOLE and SEEK_DATA, if available.
22 - work around (again!) an immensely stupid bug in RHEL, defining
23 autoconf macros in linux system headers (analysed by Paul Howarth).
24
254.14 Sat Apr 7 02:45:18 CEST 2012
26 - fix stat structure usage on windows, which caused bogus stat results.
27 - (libeio) make readahead emulation behave more like actual readahead by never failing.
28 - new request aio_seek.
29 - new request aio_fiemap.
30 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
31
324.12 Fri Dec 30 08:51:25 CET 2011
33 - realpath would return a random value if the name was too long,
34 instead of -1.
35 - port to c89.
36
374.11 Mon Oct 10 00:24:11 CEST 2011
38 - libeio didn't compile on !linux (Paul Howarth).
39
404.1 Sun Oct 9 10:24:11 CEST 2011
41 - IO::AIO did access uninitialised memory on unsuccessful stats.
42 - (libeio) added syncfs syscall wrapper.
43 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
44 - (libeio) support multiple indepenent working directories.
45 - applied speling corrections by Nicholas Bamber.
46 - tune treescan #threads and #outstanding requests a bit.
47 - reduce the number of file descriptors in use at any one time
48 in treescan, to avoid running out of them (and using too much ram).
49 - take advantage of working directoriy abstractions
50 in aio_scandir and treescan.
51 - reduce compiled size by ~10% by not inlining some key functionality.
52 - added --progress switch to treescan.
53
544.0 Mon Jul 18 05:01:10 CEST 2011
55 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
56 see FORK BEHAVIOUR in manpage for details.
57 - passes testsuite on win32 now and may actually work
58 (activestate 5.10.1 / MSVC6, YMMV).
59 - (libeio) fix a deadlock where a wakeup signal could be missed when
60 a timeout occured at the same time.
61 - (libeio) added realpath.
62 - (libeio) added fallocate.
63 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
64 - (libeio) do not acquire any locks when forking.
65 - (libeio) use fewer time() syscalls when waiting for new requests.

68 - ECB.H WAS MISSING.

703.92 Wed Jun 29 14:45:41 CEST 2011
71 - ecb.h was missing.

733.91 Wed Jun 29 13:24:42 CEST 2011
12 - (libeio) work around a Linux (and likely FreeBSD and other 74 - (libeio) work around a Linux (and likely FreeBSD and other
13 kernels) bug where sendfile would not transfer all the requested 75 kernels) bug where sendfile would not transfer all the requested
14 bytes on large transfers, using a heuristic. 76 bytes on large transfers, using a heuristic.
77 - buggy sendfile caused aio_move/copy to sometimes fail for big
78 files (fortunately it checks that the whole file has been
79 transferred...)
80 - use libecb for higher performance and higher portability.
81 - (libeio) disable sendfile on darwin, it's too broken.
82 - disable fork tests on !linux, as only linux supports mixing
83 pthread and fork in perl.
84 - document the fact that fork doesn't work anymore when using
85 this module, on anything !GNU/Linux.
86 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
87 run on a 0.1MHz cpu. Or so.

18 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST. 91 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
