42 41
43 - add MADV_FREE constant. 42 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
43 were detected by autoconf.
44
454.6 Sat Aug 25 21:58:36 CEST 2018
46 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
47 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
48 but only st_gen on openbsd because they compiled their perl without support
49 for birthtimes).
50 - fix madvise and munlock to properly support negative offsets.
51 - allocate fd for the aio_close at boot time, to guarantee it working
52 later, rather than calling abort when it fails. also avoids
53 close-on-exec race issues after module load.
54 - #undef utime on win32, maybe this helps some reports of utime hangs.
55 - minor doc improvements.
56 - minor configure cleanups.
57 - use $Config{perllibs} instead of libs for configure. might help people
58 who didn'T install all perl dependencies (might break things as well).
59
604.54 Tue Aug 14 13:54:48 CEST 2018
61 - include sys/mkdev.h or sys/sysmacros.h if available.
62 - further tweaks to configure invocation for systems requiring --rpath.
63 - no longer rely on custom paths on win32 platforms.
64 - try to work around buggy PAGESIZE macro on solaris.
65
664.53 Tue Aug 14 11:27:50 CEST 2018
67 - add $Config{libs} to LIBS for configure, to work around systems
68 with broken library dependencies (... openbsd).
69
704.52 Sun Aug 12 08:09:45 CEST 2018
71 - config.h.in was missing in distribution.
72
734.51 Sun Aug 12 07:24:14 CEST 2018
74 - complete rework of the autoconf framework: IO::AIO now uses its own
75 config.h, separate from libeio, and tries to test the actual perl
76 environment, not the standard system environment.
77 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
78 stat functions.
79 - removed non-portable C++ syntax from eio.c.
80 - try to fix readdir tests on cygwin spuriously failing.
81
824.5 Wed Aug 1 00:23:55 CEST 2018
83 - aio_mtouch touch all pages as requested, not just the first page in most cases.
84 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
85 and MREMAP_FIXED.
86 - add O_ACCMODE.
87 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
88
894.4 Tue Feb 20 07:54:12 CET 2018
90 - new aio_slurp request.
91 - add (experimental) IO::AIO::eventfd and timerfd* function.
92 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
93 - point out that aio_copy overwrites existing files.
94 - removed filesystem magic number table from aio_statvfs docs as
95 statvfs doesn't actually return this info at all (statfs does).
96 - add a bunch of (mostly linux-specific) constants for use in ioctls
97 (see aio_ioctl docs).
98 - treescan now has a proper manpage and useful --help output.
99 - new option --sync in treescan, to sync everything in a subtree.
100 - changed default for aio_msync flags to MSYNC_SYNC.
101 - document offset/length behaviour of mprotect/madvise.
102 - support linux's renameat2 (via aio_rename2).
103 - add aio_rename2, an aio_rename with flags.
104 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
105 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
106 - (libeio) use posix_close if available.
107 - (libeio) internal close() calls no longer disturb errno.
108 - add IO:AIO::FALLOC_FL_UNSHARE.
109 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
110 and better eventfd detection.

454.34 Sun May 1 19:18:24 CEST 2016 1124.34 Sun May 1 19:18:24 CEST 2016
46 - def0.h was not properly generated during previous release, causing 113 - def0.h was not properly generated during previous release, causing
47 compile errors on various platforms. 114 compile errors on various platforms.
48 - major/minor were accidentally switched (reported by Alexander Lishenyuk). 115 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
