304.19 Sun Jan 6 12:47:26 CET 2013
31 - avoid endless loop in fiemap with some XFS files.
32 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
33 and call rename/rmdir instead of renameat/unlinkat.
34
354.18 Thu Oct 11 07:01:26 CEST 2012
36 - fix unintended xthread_create by intentionalising it :)
37
384.17 Thu Oct 11 05:19:47 CEST 2012
39 - rename aio_fallocate to aio_allocate, to match documentation.
40 - add list of linux fsid values to aio_statvfs docs.
41 - work around a bug in btrfs' FIEMAP ioctl implementation.
42 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
43 as per unix spec.
44
454.16 Tue Aug 14 05:39:03 CEST 2012
46 - aio_statvfs was wromgly marked for wd emulation, causing
47 it to malfunction for paths.
48 - fix a crash in aio_fiemap, when used on ranges without any
49 extents.
50 - work around linux kernel bug (at least in 3.2): kernel might
51 trash fiemap input arguments.
52 - work around linux kernel bug (at least in 3.2): kernel does not
53 set FIEMAP_EXTENT_LAST on last segment.
54 - work around linux kernel bug (at least in 3.2): kernel silently
55 truncates segment count if a file.
56 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
57 to quick overview.
58 - splice can corrupt data.
59 - (libeio) remove pread/pwrite emulation.
60 - do not grow mmaped scalars in aio_read.
61 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
62 - provide pread/pwrite for win32, making it link again on native win32.
63
644.15 Tue Apr 10 06:59:00 CEST 2012
65 - always include linux/types.h for fiemap, for compatibility to
66 ancient systems (Paul Howarth).
67 - experimental support for IO::AIO::splice and ::tee (no aio_...).
68 - provide SEEK_HOLE and SEEK_DATA, if available.
69 - work around (again!) an immensely stupid bug in RHEL, defining
70 autoconf macros in linux system headers (analysed by Paul Howarth).
71
724.14 Sat Apr 7 02:45:18 CEST 2012
73 - fix stat structure usage on windows, which caused bogus stat results.
74 - (libeio) make readahead emulation behave more like actual readahead by never failing.
75 - new request aio_seek.
76 - new request aio_fiemap.
77 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
78
794.12 Fri Dec 30 08:51:25 CET 2011
80 - realpath would return a random value if the name was too long,
81 instead of -1.
82 - port to c89.
83
844.11 Mon Oct 10 00:24:11 CEST 2011
85 - libeio didn't compile on !linux (Paul Howarth).
86
874.1 Sun Oct 9 10:24:11 CEST 2011
88 - IO::AIO did access uninitialised memory on unsuccessful stats.
89 - (libeio) added syncfs syscall wrapper.
90 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
91 - (libeio) support multiple indepenent working directories.
92 - applied speling corrections by Nicholas Bamber.
93 - tune treescan #threads and #outstanding requests a bit.
94 - reduce the number of file descriptors in use at any one time
95 in treescan, to avoid running out of them (and using too much ram).
96 - take advantage of working directoriy abstractions
97 in aio_scandir and treescan.
98 - reduce compiled size by ~10% by not inlining some key functionality.
99 - added --progress switch to treescan.
100
1014.0 Mon Jul 18 05:01:10 CEST 2011
102 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
103 see FORK BEHAVIOUR in manpage for details.
104 - passes testsuite on win32 now and may actually work
105 (activestate 5.10.1 / MSVC6, YMMV).
106 - (libeio) fix a deadlock where a wakeup signal could be missed when
107 a timeout occured at the same time.
108 - (libeio) added realpath.
109 - (libeio) added fallocate.
110 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
111 - (libeio) do not acquire any locks when forking.
112 - (libeio) use fewer time() syscalls when waiting for new requests.
113
1143.93 Wed Jun 29 23:44:18 CEST 2011
115 - ECB.H WAS MISSING.
116
1173.92 Wed Jun 29 14:45:41 CEST 2011
118 - ecb.h was missing.
119
1203.91 Wed Jun 29 13:24:42 CEST 2011
121 - (libeio) work around a Linux (and likely FreeBSD and other
122 kernels) bug where sendfile would not transfer all the requested
123 bytes on large transfers, using a heuristic.
124 - buggy sendfile caused aio_move/copy to sometimes fail for big
125 files (fortunately it checks that the whole file has been
126 transferred...)
127 - use libecb for higher performance and higher portability.
128 - (libeio) disable sendfile on darwin, it's too broken.
129 - disable fork tests on !linux, as only linux supports mixing
130 pthread and fork in perl.
131 - document the fact that fork doesn't work anymore when using
132 this module, on anything !GNU/Linux.
133 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
134 run on a 0.1MHz cpu. Or so.
135
1363.9 Fri May 27 02:43:47 CEST 2011
137 - (libeio) fix memory corruption in aio_readdirx for the flags
138 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
139 - add lots of newer POSIX and GNU/Linux-specific open
140 flags.
141
1423.8 Sun Mar 27 12:25:33 CEST 2011
143 - use nonstandard but maybe-working-on-bsd fork technique.
144 - support a max_idle value of 0.
145 - support setting of idle timeout value (IO::AIO::idle_timeout).
146
1473.72 Fri Feb 11 04:25:38 CET 2011
148 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
149 - aio_mknod always used a dev_t value of 0.
150 - new treescan option: --grep.
151 - add more S_IF macros, and major/minor/makedev "macros".
152
1533.71 Thu Dec 30 08:18:46 CET 2010
154 - the numerical result value passed to callbacks did not stringify
155 correctly, due to internal reuse and failure to reset the sv flags.
156 - actually test for posix_[mf]advise, as at least uClibc defines
157 _POSIX_ADVISORY_INFO without actually having any of the required
158 funcitonality. ugh.
159
1603.7 Mon Nov 1 23:00:34 CET 2010
161 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
162 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
163 - document the sad state of affairs w.r.t. pthread on many bsds.
164 - do not enable mmap on systems without _POSIX_MAPPED_FILES
165 (openbsd 4.8).
29 - do not leak memory in IO::AIO::mmap when the scalar already 166 - do not leak memory in IO::AIO::mmap when the scalar already
30 had string-data. 167 had string-data.
31 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-documented 168 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
32 them. 169 them.
33 - cache the result IV, for a minor speedup in the common case. 170 - cache the result IV, for a minor speedup in the common case.
34 - croak when an mmapped-scalar changes location, to detect 171 - croak when an mmapped-scalar changes location, to detect
35 user-errors better. 172 user-errors better.
36 - fix aio_readlink prototype. 173 - fix aio_readlink prototype.
37 - add madvise, mmap, munmap, aio_mlockall, munlockall,
38 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.

403.65 Wed Mar 31 02:45:05 CEST 2010 1753.65 Wed Mar 31 02:45:05 CEST 2010
41 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not 176 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
42 cut off long pathnames in aio_readlink (based on patch by 177 cut off long pathnames in aio_readlink (based on patch by
43 Rasmus Andersson). 178 Rasmus Andersson).
