47 - add MADV_FREE constant. 42TODO: rt-4.0.18-20109-1573826674-1229.126277-5-0@rt.cpan.org
43TODO: aio_splice, aio_tee
44TODO: copy_file_range
45 - IO::AIO::splice and IO::AIO::tee didn't properly return
46 64 bit values.
47 - added IO::AIO::accept4.
48 - add various F_SEAL related fcntl constants.
49 - removed experimentla marker for fdlimit functions.
50
514.72 Wed Apr 3 04:56:03 CEST 2019
52 - (libeio) if fd 0 is available do not use it for aio_wd, as it
53 collides with IO::AIO::CWD.
54 - added IO::AIO::memfd_create.
55 - correctly include <sys/uio.h> in the vmsplice test.
56 - reduce codesize by ~7% on amd64 by declaring more functions
57 as noinline.
58 - documentation fixes and updates.
59 - experimental and undocumented preliminary support for synchronous statx.
60
614.71 Sun Mar 10 13:09:26 CET 2019
62 - due to an error in the linux manpages, the configure tests
63 for readahead, sync_file_range, splice etc. failed. This has been fixed.
64
654.7 Mon Mar 4 11:28:13 CET 2019
66 - majorly speed up scandir for the very special case of a non-POSIX
67 filesystem that nevertheless reports valid dt_type information.
68 The only known filesystem of this type is currently btrfs, which
69 didn't get it's act together to implement POSIX semantics in all
70 these years, and I am tired of waiting.
71 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
72 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
73 were detected by autoconf.
74
754.6 Sat Aug 25 21:58:36 CEST 2018
76 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
77 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
78 but only st_gen on openbsd because they compiled their perl without support
79 for birthtimes).
80 - fix madvise and munlock to properly support negative offsets.
81 - allocate fd for the aio_close at boot time, to guarantee it working
82 later, rather than calling abort when it fails. also avoids
83 close-on-exec race issues after module load.
84 - #undef utime on win32, maybe this helps some reports of utime hangs.
85 - minor doc improvements.
86 - minor configure cleanups.
87 - use $Config{perllibs} instead of libs for configure. might help people
88 who didn't install all perl dependencies (might break things as well).
89
904.54 Tue Aug 14 13:54:48 CEST 2018
91 - include sys/mkdev.h or sys/sysmacros.h if available.
92 - further tweaks to configure invocation for systems requiring --rpath.
93 - no longer rely on custom paths on win32 platforms.
94 - try to work around buggy PAGESIZE macro on solaris.
95
964.53 Tue Aug 14 11:27:50 CEST 2018
97 - add $Config{libs} to LIBS for configure, to work around systems
98 with broken library dependencies (... openbsd).
99
1004.52 Sun Aug 12 08:09:45 CEST 2018
101 - config.h.in was missing in distribution.
102
1034.51 Sun Aug 12 07:24:14 CEST 2018
104 - complete rework of the autoconf framework: IO::AIO now uses its own
105 config.h, separate from libeio, and tries to test the actual perl
106 environment, not the standard system environment.
107 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
108 stat functions.
109 - removed non-portable C++ syntax from eio.c.
110 - try to fix readdir tests on cygwin spuriously failing.
111
1124.5 Wed Aug 1 00:23:55 CEST 2018
113 - aio_mtouch touch all pages as requested, not just the first page in most cases.
114 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
115 and MREMAP_FIXED.
116 - add O_ACCMODE.
117 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
118
1194.4 Tue Feb 20 07:54:12 CET 2018
120 - new aio_slurp request.
121 - add (experimental) IO::AIO::eventfd and timerfd* function.
122 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
123 - point out that aio_copy overwrites existing files.
124 - removed filesystem magic number table from aio_statvfs docs as
125 statvfs doesn't actually return this info at all (statfs does).
48 - add a bunch of (mostly linux-specific) constants for use in ioctls 126 - add a bunch of (mostly linux-specific) constants for use in ioctls
49 (see aio_ioctl docs). 127 (see aio_ioctl docs).
50 - treescan now has a proper manpage and useful --help output. 128 - treescan now has a proper manpage and useful --help output.
51 - new option --sync in treescan, to sync everything in a subtree. 129 - new option --sync in treescan, to sync everything in a subtree.
52 - changed default for aio_msync flags to MSYNC_SYNC. 130 - changed default for aio_msync flags to MSYNC_SYNC.
53 - document offset/length behaviour of mprotect/madvise. 131 - document offset/length behaviour of mprotect/madvise.
54 - support linux's renameat2 (via aio_rename2). 132 - support linux's renameat2 (via aio_rename2).
55 - add aio_rename2, an aio_rename with flags. 133 - add aio_rename2, an aio_rename with flags.
134 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
135 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
136 - (libeio) use posix_close if available.
137 - (libeio) internal close() calls no longer disturb errno.
138 - add IO:AIO::FALLOC_FL_UNSHARE.
139 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
140 and better eventfd detection.

574.34 Sun May 1 19:18:24 CEST 2016 1424.34 Sun May 1 19:18:24 CEST 2016
58 - def0.h was not properly generated during previous release, causing 143 - def0.h was not properly generated during previous release, causing
59 compile errors on various platforms. 144 compile errors on various platforms.
60 - major/minor were accidentally switched (reported by Alexander Lishenyuk). 145 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
