424.6 Sat Aug 25 21:58:36 CEST 2018
43 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
44 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
45 but only st_gen on openbsd because they compiled their perl without support
46 for birthtimes).
47 - fix madvise and munlock to properly support negative offsets.
48 - allocate fd for the aio_close at boot time, to guarantee it working
49 later, rather than calling abort when it fails. also avoids
50 close-on-exec race issues after module load.
51 - #undef utime on win32, maybe this helps some reports of utime hangs.
52 - minor doc improvements.
53 - minor configure cleanups.
54 - use $Config{perllibs} instead of libs for configure. might help people
55 who didn'T install all perl dependencies (might break things as well).
56
574.54 Tue Aug 14 13:54:48 CEST 2018
58 - include sys/mkdev.h or sys/sysmacros.h if available.
59 - further tweaks to configure invocation for systems requiring --rpath.
60 - no longer rely on custom paths on win32 platforms.
61 - try to work around buggy PAGESIZE macro on solaris.
62
634.53 Tue Aug 14 11:27:50 CEST 2018
64 - add $Config{libs} to LIBS for configure, to work around systems
65 with broken library dependencies (... openbsd).
66
674.52 Sun Aug 12 08:09:45 CEST 2018
68 - config.h.in was missing in distribution.
69
704.51 Sun Aug 12 07:24:14 CEST 2018
71 - complete rework of the autoconf framework: IO::AIO now uses its own
72 config.h, separate from libeio, and tries to test the actual perl
73 environment, not the standard system environment.
74 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
75 stat functions.
76 - removed non-portable C++ syntax from eio.c.
77 - try to fix readdir tests on cygwin spuriously failing.
78
794.5 Wed Aug 1 00:23:55 CEST 2018
80 - aio_mtouch touch all pages as requested, not just the first page in most cases.
81 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
82 and MREMAP_FIXED.
83 - add O_ACCMODE.
84 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
85
864.4 Tue Feb 20 07:54:12 CET 2018
87 - new aio_slurp request.
88 - add (experimental) IO::AIO::eventfd and timerfd* function.
89 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
90 - point out that aio_copy overwrites existing files.
91 - removed filesystem magic number table from aio_statvfs docs as
92 statvfs doesn't actually return this info at all (statfs does).
93 - add a bunch of (mostly linux-specific) constants for use in ioctls
94 (see aio_ioctl docs).
95 - treescan now has a proper manpage and useful --help output.
96 - new option --sync in treescan, to sync everything in a subtree.
97 - changed default for aio_msync flags to MSYNC_SYNC.
98 - document offset/length behaviour of mprotect/madvise.
99 - support linux's renameat2 (via aio_rename2).
100 - add aio_rename2, an aio_rename with flags.
101 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
102 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
103 - (libeio) use posix_close if available.
104 - (libeio) internal close() calls no longer disturb errno.
105 - add IO:AIO::FALLOC_FL_UNSHARE.
106 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
107 and better eventfd detection.
108
1094.34 Sun May 1 19:18:24 CEST 2016
110 - def0.h was not properly generated during previous release, causing
111 compile errors on various platforms.
112 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
40 - removed duplicate definition of MAP_HUGETLB, that was found due to 113 - removed duplicate definition of MAP_HUGETLB, that was found due to
41 a bug in Perl::Tidy (testcase by alaska332@gmail.com). 114 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
115 - added (untested!) aio_fcntl, aio_ioctl requests.
116 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
117 as manpages-dev originally claimed.

434.33 Mon Jan 18 12:50:10 CET 2016 1194.33 Mon Jan 18 12:50:10 CET 2016
44 - add IO::AIO::pipe2 function. 120 - add IO::AIO::pipe2 function.
45 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE 121 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
46 constants. 122 constants.
