13 - add list of linux fsid values to aio_statvfs docs.
14
154.16 Tue Aug 14 05:39:03 CEST 2012
16 - aio_statvfs was wromgly marked for wd emulation, causing
17 it to malfunctiobn for paths.
18 - fix a crash in aio_fiemap, when used on ranges without any
19 extents.
20 - work around linux kernel bug (at least in 3.2): kernel might
21 trash fiemap input arguments.
22 - work around linux kernel bug (at least in 3.2): kernel does not
23 set FIEMAP_EXTENT_LAST on last segment.
24 - work around linux kernel bug (at least in 3.2): kernel silently
25 truncates segment count if a file.
26 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
27 to quick overview.
28 - splice can corrupt data.
29 - (libeio) remove pread/pwrite emulation.
30 - do not grow mmaped scalars in aio_read.
31 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
32 - provide pread/pwrite for win32, making it link again on native win32.
33
344.15 Tue Apr 10 06:59:00 CEST 2012
35 - always include linux/types.h for fiemap, for compatibility to
36 ancient systems (Paul Howarth).
37 - experimental support for IO::AIO::splice and ::tee (no aio_...).
38 - provide SEEK_HOLE and SEEK_DATA, if available.
39 - work around (again!) an immensely stupid bug in RHEL, defining
40 autoconf macros in linux system headers (analysed by Paul Howarth).
41
424.14 Sat Apr 7 02:45:18 CEST 2012
43 - fix stat structure usage on windows, which caused bogus stat results.
44 - (libeio) make readahead emulation behave more like actual readahead by never failing.
45 - new request aio_seek.
46 - new request aio_fiemap.
47 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
48
494.12 Fri Dec 30 08:51:25 CET 2011
50 - realpath would return a random value if the name was too long,
51 instead of -1.
52 - port to c89.
53
544.11 Mon Oct 10 00:24:11 CEST 2011
55 - libeio didn't compile on !linux (Paul Howarth).
56
574.1 Sun Oct 9 10:24:11 CEST 2011
58 - IO::AIO did access uninitialised memory on unsuccessful stats.
59 - (libeio) added syncfs syscall wrapper.
60 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
61 - (libeio) support multiple indepenent working directories.
62 - applied speling corrections by Nicholas Bamber.
63 - tune treescan #threads and #outstanding requests a bit.
64 - reduce the number of file descriptors in use at any one time
65 in treescan, to avoid running out of them (and using too much ram).
66 - take advantage of working directoriy abstractions
67 in aio_scandir and treescan.
68 - reduce compiled size by ~10% by not inlining some key functionality.
69 - added --progress switch to treescan.
70
714.0 Mon Jul 18 05:01:10 CEST 2011
72 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
73 see FORK BEHAVIOUR in manpage for details.
74 - passes testsuite on win32 now and may actually work
75 (activestate 5.10.1 / MSVC6, YMMV).
76 - (libeio) fix a deadlock where a wakeup signal could be missed when
77 a timeout occured at the same time.
78 - (libeio) added realpath.
79 - (libeio) added fallocate.
80 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
81 - (libeio) do not acquire any locks when forking.
82 - (libeio) use fewer time() syscalls when waiting for new requests.
83
843.93 Wed Jun 29 23:44:18 CEST 2011
85 - ECB.H WAS MISSING.
86
873.92 Wed Jun 29 14:45:41 CEST 2011
88 - ecb.h was missing.
89
903.91 Wed Jun 29 13:24:42 CEST 2011
91 - (libeio) work around a Linux (and likely FreeBSD and other
92 kernels) bug where sendfile would not transfer all the requested
93 bytes on large transfers, using a heuristic.
94 - buggy sendfile caused aio_move/copy to sometimes fail for big
95 files (fortunately it checks that the whole file has been
96 transferred...)
97 - use libecb for higher performance and higher portability.
98 - (libeio) disable sendfile on darwin, it's too broken.
99 - disable fork tests on !linux, as only linux supports mixing
100 pthread and fork in perl.
101 - document the fact that fork doesn't work anymore when using
102 this module, on anything !GNU/Linux.
103 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
104 run on a 0.1MHz cpu. Or so.
105
1063.9 Fri May 27 02:43:47 CEST 2011
107 - (libeio) fix memory corruption in aio_readdirx for the flags
108 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
109 - add lots of newer POSIX and GNU/Linux-specific open
110 flags.
111
1123.8 Sun Mar 27 12:25:33 CEST 2011
113 - use nonstandard but maybe-working-on-bsd fork technique.
114 - support a max_idle value of 0.
115 - support setting of idle timeout value (IO::AIO::idle_timeout).
116
1173.72 Fri Feb 11 04:25:38 CET 2011
118 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
119 - aio_mknod always used a dev_t value of 0.
120 - new treescan option: --grep.
121 - add more S_IF macros, and major/minor/makedev "macros".
122
1233.71 Thu Dec 30 08:18:46 CET 2010
124 - the numerical result value passed to callbacks did not stringify
125 correctly, due to internal reuse and failure to reset the sv flags.
126 - actually test for posix_[mf]advise, as at least uClibc defines
127 _POSIX_ADVISORY_INFO without actually having any of the required
128 funcitonality. ugh.
12 129
133.7 Mon Nov 1 23:00:34 CET 2010 1303.7 Mon Nov 1 23:00:34 CET 2010
14 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall, 131 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
15 aio_mlock, munlock, msync and mtouch to @EXPORT_OK. 132 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
16 - document the sad state of affairs w.r.t. pthread on many bsds. 133 - document the sad state of affairs w.r.t. pthread on many bsds.
