50
51 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
52 - add fexecve.
53 - add lots of missing functions to @EXPORT_OK.
54
554.76 Tue Jul 27 20:45:01 CEST 2021
56 - add autoconf test for siginfo_t, which is, of course, not
57 available on windows (reported by Peter Petky).
58 - disable syscalls on solaris, as perl seems to provide an
59 incompatible syscall prototype that clashes with sys/syscall.h.
60 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
61 MAP_UNINITIALIZED.
62
634.75 Wed Dec 30 08:44:55 CET 2020
64 - removed leftover debug output from treescan.
65 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
66 FSCONFIG_*, MOUNT_ATTR_* constants.
67
684.74 Tue Dec 29 16:19:28 CET 2020
69 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
70 - rework bin/treescan to avoid recursion. This fixes two bugs
71 where a deep directory traversal or a lot of command line
72 arguments could cause it to crash.
73 - added (but not documented) open_tree, AT_* and move_mount flags.
74 - support defining syscall numbers in gendef0.
75
764.73 Fri Dec 4 02:08:37 CET 2020
77 - def0.h was not uptodate, running into musl problems
78 (reported by B Fraser).
79 - IO::AIO::splice and IO::AIO::tee didn't properly return
80 64 bit values.
81 - added IO::AIO::accept4.
82 - add various F_SEAL related fcntl constants.
83 - removed experimental marker for fdlimit functions.
84 - fiemap now includes the last segment even if it overflows
85 the end offset, which is arguably the correct behaviour.
86
874.72 Wed Apr 3 04:56:03 CEST 2019
88 - (libeio) if fd 0 is available do not use it for aio_wd, as it
89 collides with IO::AIO::CWD.
90 - added IO::AIO::memfd_create.
91 - correctly include <sys/uio.h> in the vmsplice test.
92 - reduce codesize by ~7% on amd64 by declaring more functions
93 as noinline.
94 - documentation fixes and updates.
95 - experimental and undocumented preliminary support for synchronous statx.
96
974.71 Sun Mar 10 13:09:26 CET 2019
98 - due to an error in the linux manpages, the configure tests
99 for readahead, sync_file_range, splice etc. failed. This has been fixed.
100
1014.7 Mon Mar 4 11:28:13 CET 2019
102 - majorly speed up scandir for the very special case of a non-POSIX
103 filesystem that nevertheless reports valid dt_type information.
104 The only known filesystem of this type is currently btrfs, which
105 didn't get it's act together to implement POSIX semantics in all
106 these years, and I am tired of waiting.
107 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
108 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
109 were detected by autoconf.
110
1114.6 Sat Aug 25 21:58:36 CEST 2018
112 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
113 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
114 but only st_gen on openbsd because they compiled their perl without support
115 for birthtimes).
116 - fix madvise and munlock to properly support negative offsets.
117 - allocate fd for the aio_close at boot time, to guarantee it working
118 later, rather than calling abort when it fails. also avoids
119 close-on-exec race issues after module load.
120 - #undef utime on win32, maybe this helps some reports of utime hangs.
121 - minor doc improvements.
122 - minor configure cleanups.
123 - use $Config{perllibs} instead of libs for configure. might help people
124 who didn't install all perl dependencies (might break things as well).
125
1264.54 Tue Aug 14 13:54:48 CEST 2018
127 - include sys/mkdev.h or sys/sysmacros.h if available.
128 - further tweaks to configure invocation for systems requiring --rpath.
129 - no longer rely on custom paths on win32 platforms.
130 - try to work around buggy PAGESIZE macro on solaris.
131
1324.53 Tue Aug 14 11:27:50 CEST 2018
133 - add $Config{libs} to LIBS for configure, to work around systems
134 with broken library dependencies (... openbsd).
135
1364.52 Sun Aug 12 08:09:45 CEST 2018
137 - config.h.in was missing in distribution.
138
1394.51 Sun Aug 12 07:24:14 CEST 2018
140 - complete rework of the autoconf framework: IO::AIO now uses its own
141 config.h, separate from libeio, and tries to test the actual perl
142 environment, not the standard system environment.
143 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
144 stat functions.
145 - removed non-portable C++ syntax from eio.c.
146 - try to fix readdir tests on cygwin spuriously failing.
147
1484.5 Wed Aug 1 00:23:55 CEST 2018
149 - aio_mtouch touch all pages as requested, not just the first page in most cases.
150 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
151 and MREMAP_FIXED.
152 - add O_ACCMODE.
153 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
154
1554.4 Tue Feb 20 07:54:12 CET 2018
156 - new aio_slurp request.
157 - add (experimental) IO::AIO::eventfd and timerfd* function.
158 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
159 - point out that aio_copy overwrites existing files.
160 - removed filesystem magic number table from aio_statvfs docs as
161 statvfs doesn't actually return this info at all (statfs does).
162 - add a bunch of (mostly linux-specific) constants for use in ioctls
163 (see aio_ioctl docs).
164 - treescan now has a proper manpage and useful --help output.
165 - new option --sync in treescan, to sync everything in a subtree.
166 - changed default for aio_msync flags to MSYNC_SYNC.
167 - document offset/length behaviour of mprotect/madvise.
168 - support linux's renameat2 (via aio_rename2).
169 - add aio_rename2, an aio_rename with flags.
170 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
171 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
172 - (libeio) use posix_close if available.
173 - (libeio) internal close() calls no longer disturb errno.
174 - add IO:AIO::FALLOC_FL_UNSHARE.
175 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
176 and better eventfd detection.
41 177
424.34 Sun May 1 19:18:24 CEST 2016 1784.34 Sun May 1 19:18:24 CEST 2016
43 - def0.h was not properly generated during previous release, causing 179 - def0.h was not properly generated during previous release, causing
44 compile errors on various platforms. 180 compile errors on various platforms.
45 - major/minor were accidentally switched (reported by Alexander Lishenyuk). 181 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
