11 12
12 const_iv (O_ASYNC) 13 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
13 const_iv (O_DIRECT) 14 to quick overview.
14 const_iv (O_NOATIME) 15 - splice can corrupt data.
16 - (libeio) remove pread/pwrite emulation.
17 - do not grow mmaped scalars in aio_read.
18 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
19 - fix a crash in aio_fiemap, when used on files without any
20 extents.

16 const_iv (O_CLOEXEC) 224.15 Tue Apr 10 06:59:00 CEST 2012
17 const_iv (O_NOCTTY) 23 - always include linux/types.h for fiemap, for compatibility to
18 const_iv (O_NOFOLLOW) 24 ancient systems (Paul Howarth).
19 const_iv (O_NONBLOCK) 25 - experimental support for IO::AIO::splice and ::tee (no aio_...).
20 const_iv (O_EXEC) 26 - provide SEEK_HOLE and SEEK_DATA, if available.
21 const_iv (O_SEARCH) 27 - work around (again!) an immensely stupid bug in RHEL, defining
22 const_iv (O_DIRECTORY) 28 autoconf macros in linux system headers (analysed by Paul Howarth).
23 const_iv (O_DSYNC)
24 const_iv (O_RSYNC)
25 const_iv (O_SYNC)
26 const_iv (O_TTY_INIT)

304.14 Sat Apr 7 02:45:18 CEST 2012
31 - fix stat structure usage on windows, which caused bogus stat results.
32 - (libeio) make readahead emulation behave more like actual readahead by never failing.
33 - new request aio_seek.
34 - new request aio_fiemap.
35 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
36
374.12 Fri Dec 30 08:51:25 CET 2011
38 - realpath would return a random value if the name was too long,
39 instead of -1.
40 - port to c89.
41
424.11 Mon Oct 10 00:24:11 CEST 2011
43 - libeio didn't compile on !linux (Paul Howarth).
44
454.1 Sun Oct 9 10:24:11 CEST 2011
46 - IO::AIO did access uninitialised memory on unsuccessful stats.
47 - (libeio) added syncfs syscall wrapper.
48 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
49 - (libeio) support multiple indepenent working directories.
50 - applied speling corrections by Nicholas Bamber.
51 - tune treescan #threads and #outstanding requests a bit.
52 - reduce the number of file descriptors in use at any one time
53 in treescan, to avoid running out of them (and using too much ram).
54 - take advantage of working directoriy abstractions
55 in aio_scandir and treescan.
56 - reduce compiled size by ~10% by not inlining some key functionality.
57 - added --progress switch to treescan.
58
594.0 Mon Jul 18 05:01:10 CEST 2011
60 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
61 see FORK BEHAVIOUR in manpage for details.
62 - passes testsuite on win32 now and may actually work
63 (activestate 5.10.1 / MSVC6, YMMV).
64 - (libeio) fix a deadlock where a wakeup signal could be missed when
65 a timeout occured at the same time.
66 - (libeio) added realpath.
67 - (libeio) added fallocate.
68 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
69 - (libeio) do not acquire any locks when forking.
70 - (libeio) use fewer time() syscalls when waiting for new requests.
71
723.93 Wed Jun 29 23:44:18 CEST 2011
73 - ECB.H WAS MISSING.
74
753.92 Wed Jun 29 14:45:41 CEST 2011
76 - ecb.h was missing.
77
783.91 Wed Jun 29 13:24:42 CEST 2011
79 - (libeio) work around a Linux (and likely FreeBSD and other
80 kernels) bug where sendfile would not transfer all the requested
81 bytes on large transfers, using a heuristic.
82 - buggy sendfile caused aio_move/copy to sometimes fail for big
83 files (fortunately it checks that the whole file has been
84 transferred...)
85 - use libecb for higher performance and higher portability.
86 - (libeio) disable sendfile on darwin, it's too broken.
87 - disable fork tests on !linux, as only linux supports mixing
88 pthread and fork in perl.
89 - document the fact that fork doesn't work anymore when using
90 this module, on anything !GNU/Linux.
91 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
92 run on a 0.1MHz cpu. Or so.
93
943.9 Fri May 27 02:43:47 CEST 2011
95 - (libeio) fix memory corruption in aio_readdirx for the flags
96 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
97 - add lots of newer POSIX and GNU/Linux-specific open
98 flags.
28 99
293.8 Sun Mar 27 12:25:33 CEST 2011 1003.8 Sun Mar 27 12:25:33 CEST 2011
30 - use nonstandard but maybe-working-on-bsd fork technique. 101 - use nonstandard but maybe-working-on-bsd fork technique.
31 - support a max_idle value of 0. 102 - support a max_idle value of 0.
32 - support setting of idle timeout value (IO::AIO::idle_timeout). 103 - support setting of idle timeout value (IO::AIO::idle_timeout).
