384.32 Wed Feb 11 20:32:11 CET 2015
39 - replace off_t by STRLEN where appropriate, should not result in
40 user-visible changes.
41 - update ecb.h for C11 compatibility.
42
434.31 Tue Jun 3 03:29:27 CEST 2014
44 - work around more 5.20 bugs. backwards compatibility my ass.
45
464.3 Fri Apr 11 06:22:38 CEST 2014
47 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
48 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
49 in 5.18. What's so attractive about giving a shit about backwards
50 compatibility - I will never understand.
51
524.2 Sat Jan 25 01:13:14 CET 2014
53 - aio_group could corrupt memory because it didn't restore
54 the stack after req_submit.
55 - be more careful on (e.g. permission) errors in bin/treescan.
56 - work around changes in ExtUtils::MakeMaker.
57 - (libeio) implement aio_realpath for win32.
58 - (xthread) work around compile time bugs in ptw32.
59 - added IO::AIO::pipesize.
60 - (libecb) insignificant update.
61
624.19 Sun Jan 6 12:47:26 CET 2013
63 - avoid endless loop in fiemap with some XFS files.
64 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
65 and call rename/rmdir instead of renameat/unlinkat.
66
674.18 Thu Oct 11 07:01:26 CEST 2012
68 - fix unintended xthread_create by intentionalising it :)
69
704.17 Thu Oct 11 05:19:47 CEST 2012
71 - rename aio_fallocate to aio_allocate, to match documentation.
72 - add list of linux fsid values to aio_statvfs docs.
73 - work around a bug in btrfs' FIEMAP ioctl implementation.
74 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
75 as per unix spec.
76
774.16 Tue Aug 14 05:39:03 CEST 2012
78 - aio_statvfs was wromgly marked for wd emulation, causing
79 it to malfunction for paths.
80 - fix a crash in aio_fiemap, when used on ranges without any
81 extents.
82 - work around linux kernel bug (at least in 3.2): kernel might
83 trash fiemap input arguments.
84 - work around linux kernel bug (at least in 3.2): kernel does not
85 set FIEMAP_EXTENT_LAST on last segment.
86 - work around linux kernel bug (at least in 3.2): kernel silently
87 truncates segment count if a file.
88 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
89 to quick overview.
90 - splice can corrupt data.
91 - (libeio) remove pread/pwrite emulation.
92 - do not grow mmaped scalars in aio_read.
93 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
94 - provide pread/pwrite for win32, making it link again on native win32.
95
964.15 Tue Apr 10 06:59:00 CEST 2012
97 - always include linux/types.h for fiemap, for compatibility to
98 ancient systems (Paul Howarth).
99 - experimental support for IO::AIO::splice and ::tee (no aio_...).
100 - provide SEEK_HOLE and SEEK_DATA, if available.
101 - work around (again!) an immensely stupid bug in RHEL, defining
102 autoconf macros in linux system headers (analysed by Paul Howarth).
103
1044.14 Sat Apr 7 02:45:18 CEST 2012
105 - fix stat structure usage on windows, which caused bogus stat results.
106 - (libeio) make readahead emulation behave more like actual readahead by never failing.
107 - new request aio_seek.
108 - new request aio_fiemap.
109 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
110
1114.12 Fri Dec 30 08:51:25 CET 2011
112 - realpath would return a random value if the name was too long,
113 instead of -1.
114 - port to c89.
115
1164.11 Mon Oct 10 00:24:11 CEST 2011
117 - libeio didn't compile on !linux (Paul Howarth).
118
1194.1 Sun Oct 9 10:24:11 CEST 2011
120 - IO::AIO did access uninitialised memory on unsuccessful stats.
121 - (libeio) added syncfs syscall wrapper.
122 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
123 - (libeio) support multiple indepenent working directories.
124 - applied speling corrections by Nicholas Bamber.
125 - tune treescan #threads and #outstanding requests a bit.
126 - reduce the number of file descriptors in use at any one time
127 in treescan, to avoid running out of them (and using too much ram).
128 - take advantage of working directoriy abstractions
129 in aio_scandir and treescan.
130 - reduce compiled size by ~10% by not inlining some key functionality.
131 - added --progress switch to treescan.
132
1334.0 Mon Jul 18 05:01:10 CEST 2011
134 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
135 see FORK BEHAVIOUR in manpage for details.
136 - passes testsuite on win32 now and may actually work
137 (activestate 5.10.1 / MSVC6, YMMV).
138 - (libeio) fix a deadlock where a wakeup signal could be missed when
139 a timeout occured at the same time.
140 - (libeio) added realpath.
141 - (libeio) added fallocate.
142 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
143 - (libeio) do not acquire any locks when forking.
144 - (libeio) use fewer time() syscalls when waiting for new requests.
145
1463.93 Wed Jun 29 23:44:18 CEST 2011
147 - ECB.H WAS MISSING.
148
1493.92 Wed Jun 29 14:45:41 CEST 2011
150 - ecb.h was missing.
151
1523.91 Wed Jun 29 13:24:42 CEST 2011
153 - (libeio) work around a Linux (and likely FreeBSD and other
154 kernels) bug where sendfile would not transfer all the requested
155 bytes on large transfers, using a heuristic.
156 - buggy sendfile caused aio_move/copy to sometimes fail for big
157 files (fortunately it checks that the whole file has been
158 transferred...)
159 - use libecb for higher performance and higher portability.
160 - (libeio) disable sendfile on darwin, it's too broken.
161 - disable fork tests on !linux, as only linux supports mixing
162 pthread and fork in perl.
163 - document the fact that fork doesn't work anymore when using
164 this module, on anything !GNU/Linux.
165 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
166 run on a 0.1MHz cpu. Or so.
167
1683.9 Fri May 27 02:43:47 CEST 2011
169 - (libeio) fix memory corruption in aio_readdirx for the flags
170 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
171 - add lots of newer POSIX and GNU/Linux-specific open
172 flags.
173
1743.8 Sun Mar 27 12:25:33 CEST 2011
175 - use nonstandard but maybe-working-on-bsd fork technique.
176 - support a max_idle value of 0.
177 - support setting of idle timeout value (IO::AIO::idle_timeout).
178
1793.72 Fri Feb 11 04:25:38 CET 2011
13 - use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock. 180 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
181 - aio_mknod always used a dev_t value of 0.
14 - new treescan option: --grep. 182 - new treescan option: --grep.
183 - add more S_IF macros, and major/minor/makedev "macros".

17 - the numerical result value passed to callbacks did not stringify 186 - the numerical result value passed to callbacks did not stringify
18 correctly, due to internal reuse and failure to reset the sv flags. 187 correctly, due to internal reuse and failure to reset the sv flags.
19 - actually test for posix_[mf]advise, as at least uClibc defines 188 - actually test for posix_[mf]advise, as at least uClibc defines
