This has been fixed. + +4.7 Mon Mar 4 11:28:13 CET 2019 + - majorly speed up scandir for the very special case of a non-POSIX + filesystem that nevertheless reports valid dt_type information. + The only known filesystem of this type is currently btrfs, which + didn't get it's act together to implement POSIX semantics in all + these years, and I am tired of waiting. + - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall. + - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they + were detected by autoconf. + +4.6 Sat Aug 25 21:58:36 CEST 2018 + - add st_btime, st_btimesec, st_btimensec and st_gen accessors, + mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd + but only st_gen on openbsd because they compiled their perl without support + for birthtimes). + - fix madvise and munlock to properly support negative offsets. + - allocate fd for the aio_close at boot time, to guarantee it working + later, rather than calling abort when it fails. also avoids + close-on-exec race issues after module load. + - #undef utime on win32, maybe this helps some reports of utime hangs. + - minor doc improvements. + - minor configure cleanups. + - use $Config{perllibs} instead of libs for configure. might help people + who didn't install all perl dependencies (might break things as well). + +4.54 Tue Aug 14 13:54:48 CEST 2018 + - include sys/mkdev.h or sys/sysmacros.h if available. + - further tweaks to configure invocation for systems requiring --rpath. + - no longer rely on custom paths on win32 platforms. + - try to work around buggy PAGESIZE macro on solaris. + +4.53 Tue Aug 14 11:27:50 CEST 2018 + - add $Config{libs} to LIBS for configure, to work around systems + with broken library dependencies (... openbsd). + +4.52 Sun Aug 12 08:09:45 CEST 2018 + - config.h.in was missing in distribution. + +4.51 Sun Aug 12 07:24:14 CEST 2018 + - complete rework of the autoconf framework: IO::AIO now uses its own + config.h, separate from libeio, and tries to test the actual perl + environment, not the standard system environment. + - provide nanosecond-accracy stat time accessors for both perl and IO::AIO + stat functions. + - removed non-portable C++ syntax from eio.c. + - try to fix readdir tests on cygwin spuriously failing. + +4.5 Wed Aug 1 00:23:55 CEST 2018 + - aio_mtouch touch all pages as requested, not just the first page in most cases. + - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE + and MREMAP_FIXED. + - add O_ACCMODE. + - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants. + +4.4 Tue Feb 20 07:54:12 CET 2018 + - new aio_slurp request. + - add (experimental) IO::AIO::eventfd and timerfd* function. + - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit. + - point out that aio_copy overwrites existing files. + - removed filesystem magic number table from aio_statvfs docs as + statvfs doesn't actually return this info at all (statfs does). + - add a bunch of (mostly linux-specific) constants for use in ioctls + (see aio_ioctl docs). + - treescan now has a proper manpage and useful --help output. + - new option --sync in treescan, to sync everything in a subtree. + - changed default for aio_msync flags to MSYNC_SYNC. + - document offset/length behaviour of mprotect/madvise. + - support linux's renameat2 (via aio_rename2). + - add aio_rename2, an aio_rename with flags. + - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants. + - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE. + - (libeio) use posix_close if available. + - (libeio) internal close() calls no longer disturb errno. + - add IO:AIO::FALLOC_FL_UNSHARE. + - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES + and better eventfd detection. + +4.34 Sun May 1 19:18:24 CEST 2016 + - def0.h was not properly generated during previous release, causing + compile errors on various platforms. + - major/minor were accidentally switched (reported by Alexander Lishenyuk). + - removed duplicate definition of MAP_HUGETLB, that was found due to + a bug in Perl::Tidy (testcase by alaska332@gmail.com). + - added (untested!) aio_fcntl, aio_ioctl requests. + - (libeio) names set via prctl are truncated to 15 chars + nul, not 16, + as manpages-dev originally claimed. 4.33 Mon Jan 18 12:50:10 CET 2016 - add IO::AIO::pipe2 function.
