34
35 - add IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.

39 - new option --sync in treescan, to sync everything in a subtree.
40 - changed default for aio_msync flags to MSYNC_SYNC.
41 - document offset/length behaviour of mprotect/madvise.

47
484.34 Sun May 1 19:18:24 CEST 2016
49 - def0.h was not properly generated during previous release, causing
50 compile errors on various platforms.
51 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
52 - removed duplicate definition of MAP_HUGETLB, that was found due to
53 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
54 - added (untested!) aio_fcntl, aio_ioctl requests.
55 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
56 as manpages-dev originally claimed.
57
584.33 Mon Jan 18 12:50:10 CET 2016
59 - add IO::AIO::pipe2 function.
60 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
61 constants.
62 - added support for O_TMPFILE and O_PATH constants.
63 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
64 consdtants, whether they can be sensibly used or not.
65 - use NO_INIT where applicable.
66 - update libecb.
67 - added stability canary support.

69
704.32 Wed Feb 11 20:32:11 CET 2015
71 - replace off_t by STRLEN where appropriate, should not result in
72 user-visible changes.
73 - update ecb.h for C11 compatibility.
74
754.31 Tue Jun 3 03:29:27 CEST 2014
76 - work around more 5.20 bugs. backwards compatibility my ass.
77
784.3 Fri Apr 11 06:22:38 CEST 2014
79 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
80 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
81 in 5.18. What's so attractive about giving a shit about backwards
82 compatibility - I will never understand.
83
844.2 Sat Jan 25 01:13:14 CET 2014
85 - aio_group could corrupt memory because it didn't restore
86 the stack after req_submit.
87 - be more careful on (e.g. permission) errors in bin/treescan.
88 - work around changes in ExtUtils::MakeMaker.
89 - (libeio) implement aio_realpath for win32.
90 - (xthread) work around compile time bugs in ptw32.
91 - added IO::AIO::pipesize.
92 - (libecb) insignificant update.
93
944.19 Sun Jan 6 12:47:26 CET 2013
95 - avoid endless loop in fiemap with some XFS files.
96 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
97 and call rename/rmdir instead of renameat/unlinkat.
98
994.18 Thu Oct 11 07:01:26 CEST 2012
100 - fix unintended xthread_create by intentionalising it :)
101
1024.17 Thu Oct 11 05:19:47 CEST 2012
103 - rename aio_fallocate to aio_allocate, to match documentation.
104 - add list of linux fsid values to aio_statvfs docs.
105 - work around a bug in btrfs' FIEMAP ioctl implementation.
106 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
107 as per unix spec.
108
1094.16 Tue Aug 14 05:39:03 CEST 2012
110 - aio_statvfs was wromgly marked for wd emulation, causing
111 it to malfunction for paths.
112 - fix a crash in aio_fiemap, when used on ranges without any
113 extents.
114 - work around linux kernel bug (at least in 3.2): kernel might
115 trash fiemap input arguments.
116 - work around linux kernel bug (at least in 3.2): kernel does not
117 set FIEMAP_EXTENT_LAST on last segment.
118 - work around linux kernel bug (at least in 3.2): kernel silently
119 truncates segment count if a file.
120 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
121 to quick overview.
122 - splice can corrupt data.
123 - (libeio) remove pread/pwrite emulation.
124 - do not grow mmaped scalars in aio_read.
125 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
126 - provide pread/pwrite for win32, making it link again on native win32.
127
1284.15 Tue Apr 10 06:59:00 CEST 2012
129 - always include linux/types.h for fiemap, for compatibility to
130 ancient systems (Paul Howarth).
131 - experimental support for IO::AIO::splice and ::tee (no aio_...).
132 - provide SEEK_HOLE and SEEK_DATA, if available.
133 - work around (again!) an immensely stupid bug in RHEL, defining
134 autoconf macros in linux system headers (analysed by Paul Howarth).
135
1364.14 Sat Apr 7 02:45:18 CEST 2012
137 - fix stat structure usage on windows, which caused bogus stat results.
138 - (libeio) make readahead emulation behave more like actual readahead by never failing.
139 - new request aio_seek.
140 - new request aio_fiemap.
141 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
142
1434.12 Fri Dec 30 08:51:25 CET 2011
144 - realpath would return a random value if the name was too long,
145 instead of -1.
146 - port to c89.
147
1484.11 Mon Oct 10 00:24:11 CEST 2011
149 - libeio didn't compile on !linux (Paul Howarth).
150
1514.1 Sun Oct 9 10:24:11 CEST 2011
152 - IO::AIO did access uninitialised memory on unsuccessful stats.
153 - (libeio) added syncfs syscall wrapper.
154 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
155 - (libeio) support multiple indepenent working directories.
156 - applied speling corrections by Nicholas Bamber.
157 - tune treescan #threads and #outstanding requests a bit.
158 - reduce the number of file descriptors in use at any one time
159 in treescan, to avoid running out of them (and using too much ram).
160 - take advantage of working directoriy abstractions
161 in aio_scandir and treescan.
162 - reduce compiled size by ~10% by not inlining some key functionality.
163 - added --progress switch to treescan.
164
1654.0 Mon Jul 18 05:01:10 CEST 2011
166 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
167 see FORK BEHAVIOUR in manpage for details.
168 - passes testsuite on win32 now and may actually work
169 (activestate 5.10.1 / MSVC6, YMMV).
170 - (libeio) fix a deadlock where a wakeup signal could be missed when
171 a timeout occured at the same time.
172 - (libeio) added realpath.
173 - (libeio) added fallocate.
174 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
175 - (libeio) do not acquire any locks when forking.
176 - (libeio) use fewer time() syscalls when waiting for new requests.
177
1783.93 Wed Jun 29 23:44:18 CEST 2011
179 - ECB.H WAS MISSING.
180
1813.92 Wed Jun 29 14:45:41 CEST 2011
182 - ecb.h was missing.
183
1843.91 Wed Jun 29 13:24:42 CEST 2011
185 - (libeio) work around a Linux (and likely FreeBSD and other
186 kernels) bug where sendfile would not transfer all the requested
187 bytes on large transfers, using a heuristic.
188 - buggy sendfile caused aio_move/copy to sometimes fail for big
189 files (fortunately it checks that the whole file has been
190 transferred...)
191 - use libecb for higher performance and higher portability.
192 - (libeio) disable sendfile on darwin, it's too broken.
193 - disable fork tests on !linux, as only linux supports mixing
194 pthread and fork in perl.
195 - document the fact that fork doesn't work anymore when using
196 this module, on anything !GNU/Linux.
197 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
198 run on a 0.1MHz cpu. Or so.
199
2003.9 Fri May 27 02:43:47 CEST 2011
201 - (libeio) fix memory corruption in aio_readdirx for the flags
202 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.

204 flags.
205

207 - use nonstandard but maybe-working-on-bsd fork technique.
208 - support a max_idle value of 0.
209 - support setting of idle timeout value (IO::AIO::idle_timeout).
210
2113.72 Fri Feb 11 04:25:38 CET 2011
212 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
213 - aio_mknod always used a dev_t value of 0.
214 - new treescan option: --grep.
215 - add more S_IF macros, and major/minor/makedev "macros".
12 216
133.71 Thu Dec 30 08:18:46 CET 2010 2173.71 Thu Dec 30 08:18:46 CET 2010
14 - the numerical result value passed to callbacks did not stringify 218 - the numerical result value passed to callbacks did not stringify
15 correctly, due to internal reuse and failure to reset the sv flags. 219 correctly, due to internal reuse and failure to reset the sv flags.
16 - actually test for posix_[mf]advise, as at least uClibc defines 220 - actually test for posix_[mf]advise, as at least uClibc defines
