12
13 - (libeio) implement aio_realpath for win32.
14 - (xthread) work around compile time bugs in ptw32.
15
164.19 Sun Jan 6 12:47:26 CET 2013
17 - avoid endless loop in fiemap with some XFS files.
18 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
19 and call rename/rmdir instead of renameat/unlinkat.
20
214.18 Thu Oct 11 07:01:26 CEST 2012
22 - fix unintended xthread_create by intentionalising it :)
23
244.17 Thu Oct 11 05:19:47 CEST 2012
25 - rename aio_fallocate to aio_allocate, to match documentation.
26 - add list of linux fsid values to aio_statvfs docs.
27 - work around a bug in btrfs' FIEMAP ioctl implementation.
28 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
29 as per unix spec.
30
314.16 Tue Aug 14 05:39:03 CEST 2012
32 - aio_statvfs was wromgly marked for wd emulation, causing
33 it to malfunction for paths.
34 - fix a crash in aio_fiemap, when used on ranges without any
35 extents.
36 - work around linux kernel bug (at least in 3.2): kernel might
37 trash fiemap input arguments.
38 - work around linux kernel bug (at least in 3.2): kernel does not
39 set FIEMAP_EXTENT_LAST on last segment.
40 - work around linux kernel bug (at least in 3.2): kernel silently
41 truncates segment count if a file.
42 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
43 to quick overview.
44 - splice can corrupt data.
45 - (libeio) remove pread/pwrite emulation.
46 - do not grow mmaped scalars in aio_read.
47 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
48 - provide pread/pwrite for win32, making it link again on native win32.
49
504.15 Tue Apr 10 06:59:00 CEST 2012
51 - always include linux/types.h for fiemap, for compatibility to
52 ancient systems (Paul Howarth).
53 - experimental support for IO::AIO::splice and ::tee (no aio_...).
54 - provide SEEK_HOLE and SEEK_DATA, if available.
55 - work around (again!) an immensely stupid bug in RHEL, defining
56 autoconf macros in linux system headers (analysed by Paul Howarth).
57
584.14 Sat Apr 7 02:45:18 CEST 2012
59 - fix stat structure usage on windows, which caused bogus stat results.
60 - (libeio) make readahead emulation behave more like actual readahead by never failing.
61 - new request aio_seek.
62 - new request aio_fiemap.
63 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
64
654.12 Fri Dec 30 08:51:25 CET 2011
66 - realpath would return a random value if the name was too long,
67 instead of -1.
68 - port to c89.
69
704.11 Mon Oct 10 00:24:11 CEST 2011
71 - libeio didn't compile on !linux (Paul Howarth).
72
734.1 Sun Oct 9 10:24:11 CEST 2011
74 - IO::AIO did access uninitialised memory on unsuccessful stats.
75 - (libeio) added syncfs syscall wrapper.
76 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
77 - (libeio) support multiple indepenent working directories.
78 - applied speling corrections by Nicholas Bamber.
79 - tune treescan #threads and #outstanding requests a bit.
80 - reduce the number of file descriptors in use at any one time
81 in treescan, to avoid running out of them (and using too much ram).
82 - take advantage of working directoriy abstractions
83 in aio_scandir and treescan.
84 - reduce compiled size by ~10% by not inlining some key functionality.
85 - added --progress switch to treescan.
86
874.0 Mon Jul 18 05:01:10 CEST 2011
88 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
89 see FORK BEHAVIOUR in manpage for details.
90 - passes testsuite on win32 now and may actually work
91 (activestate 5.10.1 / MSVC6, YMMV).
92 - (libeio) fix a deadlock where a wakeup signal could be missed when
93 a timeout occured at the same time.
94 - (libeio) added realpath.
95 - (libeio) added fallocate.
96 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
97 - (libeio) do not acquire any locks when forking.
98 - (libeio) use fewer time() syscalls when waiting for new requests.
99
1003.93 Wed Jun 29 23:44:18 CEST 2011
101 - ECB.H WAS MISSING.
102
1033.92 Wed Jun 29 14:45:41 CEST 2011
104 - ecb.h was missing.
105
1063.91 Wed Jun 29 13:24:42 CEST 2011
107 - (libeio) work around a Linux (and likely FreeBSD and other
108 kernels) bug where sendfile would not transfer all the requested
109 bytes on large transfers, using a heuristic.
110 - buggy sendfile caused aio_move/copy to sometimes fail for big
111 files (fortunately it checks that the whole file has been
112 transferred...)
113 - use libecb for higher performance and higher portability.
114 - (libeio) disable sendfile on darwin, it's too broken.
115 - disable fork tests on !linux, as only linux supports mixing
116 pthread and fork in perl.
117 - document the fact that fork doesn't work anymore when using
118 this module, on anything !GNU/Linux.
119 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
120 run on a 0.1MHz cpu. Or so.
121
1223.9 Fri May 27 02:43:47 CEST 2011
123 - (libeio) fix memory corruption in aio_readdirx for the flags
124 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
125 - add lots of newer POSIX and GNU/Linux-specific open
126 flags.
127
1283.8 Sun Mar 27 12:25:33 CEST 2011
129 - use nonstandard but maybe-working-on-bsd fork technique.
130 - support a max_idle value of 0.
131 - support setting of idle timeout value (IO::AIO::idle_timeout).
132
1333.72 Fri Feb 11 04:25:38 CET 2011
134 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
135 - aio_mknod always used a dev_t value of 0.
136 - new treescan option: --grep.
137 - add more S_IF macros, and major/minor/makedev "macros".

14 - the numerical result value passed to callbacks did not stringify 140 - the numerical result value passed to callbacks did not stringify
15 correctly, due to internal reuse and failure to reset the sv flags. 141 correctly, due to internal reuse and failure to reset the sv flags.
16 - actually test for posix_[mf]advise, as at least uClibc defines 142 - actually test for posix_[mf]advise, as at least uClibc defines
