12 const_iv (O_ASYNC) 134.18 Thu Oct 11 07:01:26 CEST 2012
13 const_iv (O_DIRECT) 14 - fix unintended xthread_create by intentionalising it :)

17 const_iv (O_NOCTTY) 17 - rename aio_fallocate to aio_allocate, to match documentation.
18 const_iv (O_NOFOLLOW) 18 - add list of linux fsid values to aio_statvfs docs.

234.16 Tue Aug 14 05:39:03 CEST 2012
24 - aio_statvfs was wromgly marked for wd emulation, causing
25 it to malfunction for paths.
26 - fix a crash in aio_fiemap, when used on ranges without any
27 extents.
28 - work around linux kernel bug (at least in 3.2): kernel might
29 trash fiemap input arguments.
30 - work around linux kernel bug (at least in 3.2): kernel does not
31 set FIEMAP_EXTENT_LAST on last segment.
32 - work around linux kernel bug (at least in 3.2): kernel silently
33 truncates segment count if a file.
34 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
35 to quick overview.
36 - splice can corrupt data.
37 - (libeio) remove pread/pwrite emulation.
38 - do not grow mmaped scalars in aio_read.
39 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
40 - provide pread/pwrite for win32, making it link again on native win32.
41
424.15 Tue Apr 10 06:59:00 CEST 2012
43 - always include linux/types.h for fiemap, for compatibility to
44 ancient systems (Paul Howarth).
45 - experimental support for IO::AIO::splice and ::tee (no aio_...).
46 - provide SEEK_HOLE and SEEK_DATA, if available.
47 - work around (again!) an immensely stupid bug in RHEL, defining
48 autoconf macros in linux system headers (analysed by Paul Howarth).
49
504.14 Sat Apr 7 02:45:18 CEST 2012
51 - fix stat structure usage on windows, which caused bogus stat results.
52 - (libeio) make readahead emulation behave more like actual readahead by never failing.
53 - new request aio_seek.
54 - new request aio_fiemap.
55 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
56
574.12 Fri Dec 30 08:51:25 CET 2011
58 - realpath would return a random value if the name was too long,
59 instead of -1.
60 - port to c89.
61
624.11 Mon Oct 10 00:24:11 CEST 2011
63 - libeio didn't compile on !linux (Paul Howarth).
64
654.1 Sun Oct 9 10:24:11 CEST 2011
66 - IO::AIO did access uninitialised memory on unsuccessful stats.
67 - (libeio) added syncfs syscall wrapper.
68 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
69 - (libeio) support multiple indepenent working directories.
70 - applied speling corrections by Nicholas Bamber.
71 - tune treescan #threads and #outstanding requests a bit.
72 - reduce the number of file descriptors in use at any one time
73 in treescan, to avoid running out of them (and using too much ram).
74 - take advantage of working directoriy abstractions
75 in aio_scandir and treescan.
76 - reduce compiled size by ~10% by not inlining some key functionality.
77 - added --progress switch to treescan.
78
794.0 Mon Jul 18 05:01:10 CEST 2011
80 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
81 see FORK BEHAVIOUR in manpage for details.
82 - passes testsuite on win32 now and may actually work
83 (activestate 5.10.1 / MSVC6, YMMV).
84 - (libeio) fix a deadlock where a wakeup signal could be missed when
85 a timeout occured at the same time.
86 - (libeio) added realpath.
87 - (libeio) added fallocate.
88 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
89 - (libeio) do not acquire any locks when forking.
90 - (libeio) use fewer time() syscalls when waiting for new requests.
91
923.93 Wed Jun 29 23:44:18 CEST 2011
93 - ECB.H WAS MISSING.
94
953.92 Wed Jun 29 14:45:41 CEST 2011
96 - ecb.h was missing.
97
983.91 Wed Jun 29 13:24:42 CEST 2011
99 - (libeio) work around a Linux (and likely FreeBSD and other
100 kernels) bug where sendfile would not transfer all the requested
101 bytes on large transfers, using a heuristic.
102 - buggy sendfile caused aio_move/copy to sometimes fail for big
103 files (fortunately it checks that the whole file has been
104 transferred...)
105 - use libecb for higher performance and higher portability.
106 - (libeio) disable sendfile on darwin, it's too broken.
107 - disable fork tests on !linux, as only linux supports mixing
108 pthread and fork in perl.
109 - document the fact that fork doesn't work anymore when using
110 this module, on anything !GNU/Linux.
111 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
112 run on a 0.1MHz cpu. Or so.
113
1143.9 Fri May 27 02:43:47 CEST 2011
115 - (libeio) fix memory corruption in aio_readdirx for the flags
116 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
117 - add lots of newer POSIX and GNU/Linux-specific open
118 flags.
28 119
293.8 Sun Mar 27 12:25:33 CEST 2011 1203.8 Sun Mar 27 12:25:33 CEST 2011
30 - use nonstandard but maybe-working-on-bsd fork technique. 121 - use nonstandard but maybe-working-on-bsd fork technique.
31 - support a max_idle value of 0. 122 - support a max_idle value of 0.
32 - support setting of idle timeout value (IO::AIO::idle_timeout). 123 - support setting of idle timeout value (IO::AIO::idle_timeout).
