37 50
51 - add autoconf test for siginfo_t, which is, of course, not
52 working on windows (reported by Peter Petky).
53 - disable syscalls on solaris, as perl seems to provide an
54 incompatible syscall prototype that clashes with sys/syscall.h.
55 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
56 MAP_UNINITIALIZED.
57
584.75 Wed Dec 30 08:44:55 CET 2020
59 - removed leftover debug output from treescan.
60 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
61 FSCONFIG_*, MOUNT_ATTR_* constants.
62
634.74 Tue Dec 29 16:19:28 CET 2020
64 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
65 - rework bin/treescan to avoid recursion. This fixes two bugs
66 where a deep directory traversal or a lot of command line
67 arguments could cause it to crash.
68 - added (but not documented) open_tree, AT_* and move_mount flags.
69 - support defining syscall numbers in gendef0.
70
714.73 Fri Dec 4 02:08:37 CET 2020
72 - def0.h was not uptodate, running into musl problems
73 (reported by B Fraser).
74 - IO::AIO::splice and IO::AIO::tee didn't properly return
75 64 bit values.
76 - added IO::AIO::accept4.
77 - add various F_SEAL related fcntl constants.
78 - removed experimental marker for fdlimit functions.
79 - fiemap now includes the last segment even if it overflows
80 the end offset, which is arguably the correct behaviour.
81
824.72 Wed Apr 3 04:56:03 CEST 2019
83 - (libeio) if fd 0 is available do not use it for aio_wd, as it
84 collides with IO::AIO::CWD.
85 - added IO::AIO::memfd_create.
86 - correctly include <sys/uio.h> in the vmsplice test.
87 - reduce codesize by ~7% on amd64 by declaring more functions
88 as noinline.
89 - documentation fixes and updates.
90 - experimental and undocumented preliminary support for synchronous statx.
91
924.71 Sun Mar 10 13:09:26 CET 2019
93 - due to an error in the linux manpages, the configure tests
94 for readahead, sync_file_range, splice etc. failed. This has been fixed.
95
964.7 Mon Mar 4 11:28:13 CET 2019
97 - majorly speed up scandir for the very special case of a non-POSIX
98 filesystem that nevertheless reports valid dt_type information.
99 The only known filesystem of this type is currently btrfs, which
100 didn't get it's act together to implement POSIX semantics in all
101 these years, and I am tired of waiting.
102 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
103 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
104 were detected by autoconf.
105
1064.6 Sat Aug 25 21:58:36 CEST 2018
107 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
108 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
109 but only st_gen on openbsd because they compiled their perl without support
110 for birthtimes).
111 - fix madvise and munlock to properly support negative offsets.
112 - allocate fd for the aio_close at boot time, to guarantee it working
113 later, rather than calling abort when it fails. also avoids
114 close-on-exec race issues after module load.
115 - #undef utime on win32, maybe this helps some reports of utime hangs.
116 - minor doc improvements.
117 - minor configure cleanups.
118 - use $Config{perllibs} instead of libs for configure. might help people
119 who didn't install all perl dependencies (might break things as well).
120
1214.54 Tue Aug 14 13:54:48 CEST 2018
122 - include sys/mkdev.h or sys/sysmacros.h if available.
123 - further tweaks to configure invocation for systems requiring --rpath.
124 - no longer rely on custom paths on win32 platforms.
125 - try to work around buggy PAGESIZE macro on solaris.
126
1274.53 Tue Aug 14 11:27:50 CEST 2018
128 - add $Config{libs} to LIBS for configure, to work around systems
129 with broken library dependencies (... openbsd).
130
1314.52 Sun Aug 12 08:09:45 CEST 2018
132 - config.h.in was missing in distribution.
133
1344.51 Sun Aug 12 07:24:14 CEST 2018
135 - complete rework of the autoconf framework: IO::AIO now uses its own
136 config.h, separate from libeio, and tries to test the actual perl
137 environment, not the standard system environment.
138 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
139 stat functions.
140 - removed non-portable C++ syntax from eio.c.
141 - try to fix readdir tests on cygwin spuriously failing.
142
1434.5 Wed Aug 1 00:23:55 CEST 2018
144 - aio_mtouch touch all pages as requested, not just the first page in most cases.
145 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
146 and MREMAP_FIXED.
147 - add O_ACCMODE.
148 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
149
1504.4 Tue Feb 20 07:54:12 CET 2018
151 - new aio_slurp request.
152 - add (experimental) IO::AIO::eventfd and timerfd* function.
153 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
154 - point out that aio_copy overwrites existing files.
155 - removed filesystem magic number table from aio_statvfs docs as
156 statvfs doesn't actually return this info at all (statfs does).
157 - add a bunch of (mostly linux-specific) constants for use in ioctls
158 (see aio_ioctl docs).
159 - treescan now has a proper manpage and useful --help output.
160 - new option --sync in treescan, to sync everything in a subtree.
161 - changed default for aio_msync flags to MSYNC_SYNC.
162 - document offset/length behaviour of mprotect/madvise.
163 - support linux's renameat2 (via aio_rename2).
164 - add aio_rename2, an aio_rename with flags.
165 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
166 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
167 - (libeio) use posix_close if available.
168 - (libeio) internal close() calls no longer disturb errno.
169 - add IO:AIO::FALLOC_FL_UNSHARE.
170 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
171 and better eventfd detection.
172
1734.34 Sun May 1 19:18:24 CEST 2016
174 - def0.h was not properly generated during previous release, causing
175 compile errors on various platforms.
176 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
177 - removed duplicate definition of MAP_HUGETLB, that was found due to
178 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
179 - added (untested!) aio_fcntl, aio_ioctl requests.
180 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
181 as manpages-dev originally claimed.
182
1834.33 Mon Jan 18 12:50:10 CET 2016
38 - add IO::AIO::pipe2 function. 184 - add IO::AIO::pipe2 function.
39 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE 185 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
40 constants. 186 constants.
41 - added support for O_TMPFILE and O_PATH constants. 187 - added support for O_TMPFILE and O_PATH constants.
42 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK 188 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
43 consdtants, whether they can be sensibly used or not. 189 consdtants, whether they can be sensibly used or not.
44 - use NO_INIT where applicable. 190 - use NO_INIT where applicable.
45 - update libecb. 191 - update libecb.
46 - added stability canary support. 192 - added stability canary support.

47 194
484.32 Wed Feb 11 20:32:11 CET 2015 1954.32 Wed Feb 11 20:32:11 CET 2015
49 - replace off_t by STRLEN where appropriate, should not result in 196 - replace off_t by STRLEN where appropriate, should not result in
50 user-visible changes. 197 user-visible changes.
