49 (see aio_ioctl docs).

51 - new option --sync in treescan, to sync everything in a subtree.
52 - changed default for aio_msync flags to MSYNC_SYNC.
53 - document offset/length behaviour of mprotect/madvise.
54 - support linux's renameat2 (via aio_rename2).

56
574.34 Sun May 1 19:18:24 CEST 2016
58 - def0.h was not properly generated during previous release, causing
59 compile errors on various platforms.
60 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
61 - removed duplicate definition of MAP_HUGETLB, that was found due to
62 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
63 - added (untested!) aio_fcntl, aio_ioctl requests.
64 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
65 as manpages-dev originally claimed.
66
674.33 Mon Jan 18 12:50:10 CET 2016
68 - add IO::AIO::pipe2 function.
69 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
70 constants.
71 - added support for O_TMPFILE and O_PATH constants.
72 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
73 consdtants, whether they can be sensibly used or not.
74 - use NO_INIT where applicable.
75 - update libecb.
76 - added stability canary support.
77 - updated linux super magic table to 4.3.3.
78
794.32 Wed Feb 11 20:32:11 CET 2015
80 - replace off_t by STRLEN where appropriate, should not result in

85 - work around more 5.20 bugs. backwards compatibility my ass.
86
874.3 Fri Apr 11 06:22:38 CEST 2014
88 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
89 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
90 in 5.18. What's so attractive about giving a shit about backwards
91 compatibility - I will never understand.
92
934.2 Sat Jan 25 01:13:14 CET 2014
94 - aio_group could corrupt memory because it didn't restore
95 the stack after req_submit.
96 - be more careful on (e.g. permission) errors in bin/treescan.
97 - work around changes in ExtUtils::MakeMaker.
98 - (libeio) implement aio_realpath for win32.
99 - (xthread) work around compile time bugs in ptw32.
100 - added IO::AIO::pipesize.
101 - (libecb) insignificant update.
102
1034.19 Sun Jan 6 12:47:26 CET 2013
104 - avoid endless loop in fiemap with some XFS files.
105 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
106 and call rename/rmdir instead of renameat/unlinkat.
107
1084.18 Thu Oct 11 07:01:26 CEST 2012
109 - fix unintended xthread_create by intentionalising it :)
110
1114.17 Thu Oct 11 05:19:47 CEST 2012
112 - rename aio_fallocate to aio_allocate, to match documentation.
113 - add list of linux fsid values to aio_statvfs docs.
114 - work around a bug in btrfs' FIEMAP ioctl implementation.
115 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
116 as per unix spec.
117
1184.16 Tue Aug 14 05:39:03 CEST 2012
119 - aio_statvfs was wromgly marked for wd emulation, causing
120 it to malfunction for paths.
121 - fix a crash in aio_fiemap, when used on ranges without any
122 extents.
123 - work around linux kernel bug (at least in 3.2): kernel might
124 trash fiemap input arguments.
125 - work around linux kernel bug (at least in 3.2): kernel does not
126 set FIEMAP_EXTENT_LAST on last segment.
127 - work around linux kernel bug (at least in 3.2): kernel silently
128 truncates segment count if a file.
129 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
130 to quick overview.
131 - splice can corrupt data.
132 - (libeio) remove pread/pwrite emulation.
133 - do not grow mmaped scalars in aio_read.
134 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
135 - provide pread/pwrite for win32, making it link again on native win32.
136
1374.15 Tue Apr 10 06:59:00 CEST 2012
138 - always include linux/types.h for fiemap, for compatibility to
139 ancient systems (Paul Howarth).
140 - experimental support for IO::AIO::splice and ::tee (no aio_...).
141 - provide SEEK_HOLE and SEEK_DATA, if available.
142 - work around (again!) an immensely stupid bug in RHEL, defining
143 autoconf macros in linux system headers (analysed by Paul Howarth).
144
1454.14 Sat Apr 7 02:45:18 CEST 2012
146 - fix stat structure usage on windows, which caused bogus stat results.
147 - (libeio) make readahead emulation behave more like actual readahead by never failing.
148 - new request aio_seek.
149 - new request aio_fiemap.
150 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
151
1524.12 Fri Dec 30 08:51:25 CET 2011
153 - realpath would return a random value if the name was too long,
154 instead of -1.
155 - port to c89.
156
1574.11 Mon Oct 10 00:24:11 CEST 2011
158 - libeio didn't compile on !linux (Paul Howarth).
159
1604.1 Sun Oct 9 10:24:11 CEST 2011
161 - IO::AIO did access uninitialised memory on unsuccessful stats.
162 - (libeio) added syncfs syscall wrapper.
163 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
164 - (libeio) support multiple indepenent working directories.
165 - applied speling corrections by Nicholas Bamber.
166 - tune treescan #threads and #outstanding requests a bit.
167 - reduce the number of file descriptors in use at any one time
168 in treescan, to avoid running out of them (and using too much ram).
169 - take advantage of working directoriy abstractions
170 in aio_scandir and treescan.
171 - reduce compiled size by ~10% by not inlining some key functionality.
172 - added --progress switch to treescan.
173
1744.0 Mon Jul 18 05:01:10 CEST 2011
175 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
176 see FORK BEHAVIOUR in manpage for details.
177 - passes testsuite on win32 now and may actually work
178 (activestate 5.10.1 / MSVC6, YMMV).
179 - (libeio) fix a deadlock where a wakeup signal could be missed when
180 a timeout occured at the same time.
181 - (libeio) added realpath.
182 - (libeio) added fallocate.
183 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
184 - (libeio) do not acquire any locks when forking.
185 - (libeio) use fewer time() syscalls when waiting for new requests.
186
1873.93 Wed Jun 29 23:44:18 CEST 2011

189

191 - ecb.h was missing.
192
1933.91 Wed Jun 29 13:24:42 CEST 2011
12 - (libeio) work around a Linux (and likely FreeBSD and other 194 - (libeio) work around a Linux (and likely FreeBSD and other
13 kernels) bug where sendfile would not transfer all the requested 195 kernels) bug where sendfile would not transfer all the requested
14 bytes on large transfers, using a heuristic. 196 bytes on large transfers, using a heuristic.
15 - buggy sendfile caused aio_move/copy to sometimes fail for big 197 - buggy sendfile caused aio_move/copy to sometimes fail for big
16 files (fortunately it vchecks that the whole file has been 198 files (fortunately it checks that the whole file has been
17 transferred...) 199 transferred...)
200 - use libecb for higher performance and higher portability.
201 - (libeio) disable sendfile on darwin, it's too broken.
202 - disable fork tests on !linux, as only linux supports mixing
203 pthread and fork in perl.
204 - document the fact that fork doesn't work anymore when using
205 this module, on anything !GNU/Linux.
206 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
207 run on a 0.1MHz cpu. Or so.
