12
13 - fix a crash in aio_fiemap, when used on files without any
14 extents.
15 - work around linux kernel bug (at least in 3.2): kernel might
16 trash fiemap input arguments.
17 - work around linux kernel bug (at least in 3.2): kernel does not
18 set FIEMAP_EXTENT_LAST on last segment.
19 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
20 to quick overview.
21 - splice can corrupt data.
22 - (libeio) remove pread/pwrite emulation.
23 - do not grow mmaped scalars in aio_read.
24 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
25
264.15 Tue Apr 10 06:59:00 CEST 2012
27 - always include linux/types.h for fiemap, for compatibility to
28 ancient systems (Paul Howarth).
29 - experimental support for IO::AIO::splice and ::tee (no aio_...).
30 - provide SEEK_HOLE and SEEK_DATA, if available.
31 - work around (again!) an immensely stupid bug in RHEL, defining
32 autoconf macros in linux system headers (analysed by Paul Howarth).
33
344.14 Sat Apr 7 02:45:18 CEST 2012
35 - fix stat structure usage on windows, which caused bogus stat results.
36 - (libeio) make readahead emulation behave more like actual readahead by never failing.
37 - new request aio_seek.
38 - new request aio_fiemap.
39 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
40
414.12 Fri Dec 30 08:51:25 CET 2011
42 - realpath would return a random value if the name was too long,
43 instead of -1.
44 - port to c89.
45
464.11 Mon Oct 10 00:24:11 CEST 2011
47 - libeio didn't compile on !linux (Paul Howarth).
48
494.1 Sun Oct 9 10:24:11 CEST 2011
50 - IO::AIO did access uninitialised memory on unsuccessful stats.
51 - (libeio) added syncfs syscall wrapper.
52 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
53 - (libeio) support multiple indepenent working directories.
54 - applied speling corrections by Nicholas Bamber.
55 - tune treescan #threads and #outstanding requests a bit.
56 - reduce the number of file descriptors in use at any one time
57 in treescan, to avoid running out of them (and using too much ram).
58 - take advantage of working directoriy abstractions
59 in aio_scandir and treescan.
60 - reduce compiled size by ~10% by not inlining some key functionality.
61 - added --progress switch to treescan.
62
634.0 Mon Jul 18 05:01:10 CEST 2011
64 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
65 see FORK BEHAVIOUR in manpage for details.
66 - passes testsuite on win32 now and may actually work
67 (activestate 5.10.1 / MSVC6, YMMV).
68 - (libeio) fix a deadlock where a wakeup signal could be missed when
69 a timeout occured at the same time.
70 - (libeio) added realpath.
71 - (libeio) added fallocate.
72 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
73 - (libeio) do not acquire any locks when forking.
74 - (libeio) use fewer time() syscalls when waiting for new requests.
75
763.93 Wed Jun 29 23:44:18 CEST 2011
77 - ECB.H WAS MISSING.
78
793.92 Wed Jun 29 14:45:41 CEST 2011
80 - ecb.h was missing.
81
823.91 Wed Jun 29 13:24:42 CEST 2011
83 - (libeio) work around a Linux (and likely FreeBSD and other
84 kernels) bug where sendfile would not transfer all the requested
85 bytes on large transfers, using a heuristic.
86 - buggy sendfile caused aio_move/copy to sometimes fail for big
87 files (fortunately it checks that the whole file has been
88 transferred...)
89 - use libecb for higher performance and higher portability.
90 - (libeio) disable sendfile on darwin, it's too broken.
91 - disable fork tests on !linux, as only linux supports mixing
92 pthread and fork in perl.
93 - document the fact that fork doesn't work anymore when using
94 this module, on anything !GNU/Linux.
95 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
96 run on a 0.1MHz cpu. Or so.
97
983.9 Fri May 27 02:43:47 CEST 2011
99 - (libeio) fix memory corruption in aio_readdirx for the flags
100 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
101 - add lots of newer POSIX and GNU/Linux-specific open
102 flags.
12 103
133.8 Sun Mar 27 12:25:33 CEST 2011 1043.8 Sun Mar 27 12:25:33 CEST 2011
14 - use nonstandard but maybe-working-on-bsd fork technique. 105 - use nonstandard but maybe-working-on-bsd fork technique.
15 - support a max_idle value of 0. 106 - support a max_idle value of 0.
16 - support setting of idle timeout value (IO::AIO::idle_timeout). 107 - support setting of idle timeout value (IO::AIO::idle_timeout).
