404.54 Tue Aug 14 13:54:48 CEST 2018
41 - include sys/mkdev.h or sys/sysmacros.h if available.
42 - further tweaks to configure invocation for systems requiring --rpath.
43 - no longer rely on custom paths on win32 platforms.
44 - try to work around buggy PAGESIZE macro on solaris.
45
464.53 Tue Aug 14 11:27:50 CEST 2018
47 - add $Config{libs} to LIBS for configure, to work around systems
48 with broken library dependencies (... openbsd).
49
504.52 Sun Aug 12 08:09:45 CEST 2018
51 - config.h.in was missing in distribution.
52
534.51 Sun Aug 12 07:24:14 CEST 2018
54 - complete rework of the autoconf framework: IO::AIO now uses its own
55 config.h, separate from libeio, and tries to test the actual perl
56 environment, not the standard system environment.
57 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
58 stat functions.
59 - removed non-portable C++ syntax from eio.c.
60 - try to fix readdir tests on cygwin spuriously failing.
61
624.5 Wed Aug 1 00:23:55 CEST 2018
63 - aio_mtouch touch all pages as requested, not just the first page in most cases.

65 and MREMAP_FIXED.
66 - add O_ACCMODE.

71 - add (experimental) IO::AIO::eventfd and timerfd* function.
72 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
73 - point out that aio_copy overwrites existing files.
74 - removed filesystem magic number table from aio_statvfs docs as
75 statvfs doesn't actually return this info at all (statfs does).
76 - add a bunch of (mostly linux-specific) constants for use in ioctls
77 (see aio_ioctl docs).
78 - treescan now has a proper manpage and useful --help output.
79 - new option --sync in treescan, to sync everything in a subtree.
80 - changed default for aio_msync flags to MSYNC_SYNC.
81 - document offset/length behaviour of mprotect/madvise.

84 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
85 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
86 - (libeio) use posix_close if available.
87 - (libeio) internal close() calls no longer disturb errno.
88 - add IO:AIO::FALLOC_FL_UNSHARE.
89 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
90 and better eventfd detection.
91
924.34 Sun May 1 19:18:24 CEST 2016
93 - def0.h was not properly generated during previous release, causing
94 compile errors on various platforms.
95 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
96 - removed duplicate definition of MAP_HUGETLB, that was found due to
97 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
98 - added (untested!) aio_fcntl, aio_ioctl requests.
99 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
100 as manpages-dev originally claimed.
101
1024.33 Mon Jan 18 12:50:10 CET 2016
103 - add IO::AIO::pipe2 function.
104 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
105 constants.
106 - added support for O_TMPFILE and O_PATH constants.
107 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
108 consdtants, whether they can be sensibly used or not.

110 - update libecb.
111 - added stability canary support.

113
1144.32 Wed Feb 11 20:32:11 CET 2015
115 - replace off_t by STRLEN where appropriate, should not result in
116 user-visible changes.

120 - work around more 5.20 bugs. backwards compatibility my ass.
121
1224.3 Fri Apr 11 06:22:38 CEST 2014
123 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
124 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
125 in 5.18. What's so attractive about giving a shit about backwards
126 compatibility - I will never understand.
127
1284.2 Sat Jan 25 01:13:14 CET 2014
129 - aio_group could corrupt memory because it didn't restore
130 the stack after req_submit.

132 - work around changes in ExtUtils::MakeMaker.
133 - (libeio) implement aio_realpath for win32.
134 - (xthread) work around compile time bugs in ptw32.

141 and call rename/rmdir instead of renameat/unlinkat.
142
1434.18 Thu Oct 11 07:01:26 CEST 2012
144 - fix unintended xthread_create by intentionalising it :)
145
1464.17 Thu Oct 11 05:19:47 CEST 2012
147 - rename aio_fallocate to aio_allocate, to match documentation.
148 - add list of linux fsid values to aio_statvfs docs.
149 - work around a bug in btrfs' FIEMAP ioctl implementation.
150 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
151 as per unix spec.
152
1534.16 Tue Aug 14 05:39:03 CEST 2012
154 - aio_statvfs was wromgly marked for wd emulation, causing
155 it to malfunction for paths.
156 - fix a crash in aio_fiemap, when used on ranges without any
157 extents.
158 - work around linux kernel bug (at least in 3.2): kernel might
159 trash fiemap input arguments.
160 - work around linux kernel bug (at least in 3.2): kernel does not
161 set FIEMAP_EXTENT_LAST on last segment.
162 - work around linux kernel bug (at least in 3.2): kernel silently
163 truncates segment count if a file.
164 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
165 to quick overview.

171
1724.15 Tue Apr 10 06:59:00 CEST 2012
173 - always include linux/types.h for fiemap, for compatibility to
174 ancient systems (Paul Howarth).
175 - experimental support for IO::AIO::splice and ::tee (no aio_...).
176 - provide SEEK_HOLE and SEEK_DATA, if available.
177 - work around (again!) an immensely stupid bug in RHEL, defining
178 autoconf macros in linux system headers (analysed by Paul Howarth).
179
1804.14 Sat Apr 7 02:45:18 CEST 2012
12 - fix stat structure usage on windows, which caused bogus stat results. 181 - fix stat structure usage on windows, which caused bogus stat results.
