12TODO: MS_xxx, posix_fadvise, posix_madvise 49 - another workaround for the low-quality musl libc.
13TODO: realpath 50 - test for umount seperately, as it is more portable.
51 - some low-quality posix attempts (openbsd, osx) declare the availability
52 of fexecve but then don't even bother to implemnent a stub.
53
544.79 Sun 25 Sep 2022 18:25:53 CEST
55 - the autoconf result of the mount check was not used, so it failed to
56 compile on most systems (reported by crackoff@tutanota.com).
57 - work around fedora not having a working C compiler setup by design
58 (reported by Paul Howarth).
59
604.78 Tue 06 Sep 2022 12:54:43 CEST
61 - add IO::AIO::mount and IO::AIO::umount.
62 - add a bunch of symbols from sys/mount.h.
63
644.77 Mon 05 Sep 2022 02:03:38 CEST
65 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
66 - add fexecve.
67 - add lots of missing functions to @EXPORT_OK.
68
694.76 Tue Jul 27 20:45:01 CEST 2021
70 - add autoconf test for siginfo_t, which is, of course, not
71 available on windows (reported by Peter Petky).
72 - disable syscalls on solaris, as perl seems to provide an
73 incompatible syscall prototype that clashes with sys/syscall.h.
74 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
75 MAP_UNINITIALIZED.
76
774.75 Wed Dec 30 08:44:55 CET 2020
78 - removed leftover debug output from treescan.
79 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
80 FSCONFIG_*, MOUNT_ATTR_* constants.
81
824.74 Tue Dec 29 16:19:28 CET 2020
83 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
84 - rework bin/treescan to avoid recursion. This fixes two bugs
85 where a deep directory traversal or a lot of command line
86 arguments could cause it to crash.
87 - added (but not documented) open_tree, AT_* and move_mount flags.
88 - support defining syscall numbers in gendef0.
89
904.73 Fri Dec 4 02:08:37 CET 2020
91 - def0.h was not uptodate, running into musl problems
92 (reported by B Fraser).
93 - IO::AIO::splice and IO::AIO::tee didn't properly return
94 64 bit values.
95 - added IO::AIO::accept4.
96 - add various F_SEAL related fcntl constants.
97 - removed experimental marker for fdlimit functions.
98 - fiemap now includes the last segment even if it overflows
99 the end offset, which is arguably the correct behaviour.
100
1014.72 Wed Apr 3 04:56:03 CEST 2019
102 - (libeio) if fd 0 is available do not use it for aio_wd, as it
103 collides with IO::AIO::CWD.
104 - added IO::AIO::memfd_create.
105 - correctly include <sys/uio.h> in the vmsplice test.
106 - reduce codesize by ~7% on amd64 by declaring more functions
107 as noinline.
108 - documentation fixes and updates.
109 - experimental and undocumented preliminary support for synchronous statx.
110
1114.71 Sun Mar 10 13:09:26 CET 2019
112 - due to an error in the linux manpages, the configure tests
113 for readahead, sync_file_range, splice etc. failed. This has been fixed.
114
1154.7 Mon Mar 4 11:28:13 CET 2019
116 - majorly speed up scandir for the very special case of a non-POSIX
117 filesystem that nevertheless reports valid dt_type information.
118 The only known filesystem of this type is currently btrfs, which
119 didn't get it's act together to implement POSIX semantics in all
120 these years, and I am tired of waiting.
121 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
122 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
123 were detected by autoconf.
124
1254.6 Sat Aug 25 21:58:36 CEST 2018
126 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
127 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
128 but only st_gen on openbsd because they compiled their perl without support
129 for birthtimes).
130 - fix madvise and munlock to properly support negative offsets.
131 - allocate fd for the aio_close at boot time, to guarantee it working
132 later, rather than calling abort when it fails. also avoids
133 close-on-exec race issues after module load.
134 - #undef utime on win32, maybe this helps some reports of utime hangs.
135 - minor doc improvements.
136 - minor configure cleanups.
137 - use $Config{perllibs} instead of libs for configure. might help people
138 who didn't install all perl dependencies (might break things as well).
139
1404.54 Tue Aug 14 13:54:48 CEST 2018
141 - include sys/mkdev.h or sys/sysmacros.h if available.
142 - further tweaks to configure invocation for systems requiring --rpath.
143 - no longer rely on custom paths on win32 platforms.
144 - try to work around buggy PAGESIZE macro on solaris.
145
1464.53 Tue Aug 14 11:27:50 CEST 2018
147 - add $Config{libs} to LIBS for configure, to work around systems
148 with broken library dependencies (... openbsd).
149
1504.52 Sun Aug 12 08:09:45 CEST 2018
151 - config.h.in was missing in distribution.
152
1534.51 Sun Aug 12 07:24:14 CEST 2018
154 - complete rework of the autoconf framework: IO::AIO now uses its own
155 config.h, separate from libeio, and tries to test the actual perl
156 environment, not the standard system environment.
157 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
158 stat functions.
159 - removed non-portable C++ syntax from eio.c.
160 - try to fix readdir tests on cygwin spuriously failing.
161
1624.5 Wed Aug 1 00:23:55 CEST 2018
163 - aio_mtouch touch all pages as requested, not just the first page in most cases.
164 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
165 and MREMAP_FIXED.
166 - add O_ACCMODE.
167 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
168
1694.4 Tue Feb 20 07:54:12 CET 2018
170 - new aio_slurp request.
171 - add (experimental) IO::AIO::eventfd and timerfd* function.
172 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
173 - point out that aio_copy overwrites existing files.
174 - removed filesystem magic number table from aio_statvfs docs as
175 statvfs doesn't actually return this info at all (statfs does).
176 - add a bunch of (mostly linux-specific) constants for use in ioctls
177 (see aio_ioctl docs).
178 - treescan now has a proper manpage and useful --help output.
179 - new option --sync in treescan, to sync everything in a subtree.
180 - changed default for aio_msync flags to MSYNC_SYNC.
181 - document offset/length behaviour of mprotect/madvise.
182 - support linux's renameat2 (via aio_rename2).
183 - add aio_rename2, an aio_rename with flags.
184 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
185 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
186 - (libeio) use posix_close if available.
187 - (libeio) internal close() calls no longer disturb errno.
188 - add IO:AIO::FALLOC_FL_UNSHARE.
189 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
190 and better eventfd detection.
191
1924.34 Sun May 1 19:18:24 CEST 2016
193 - def0.h was not properly generated during previous release, causing
194 compile errors on various platforms.
195 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
196 - removed duplicate definition of MAP_HUGETLB, that was found due to
197 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
198 - added (untested!) aio_fcntl, aio_ioctl requests.
199 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
200 as manpages-dev originally claimed.
201
2024.33 Mon Jan 18 12:50:10 CET 2016
203 - add IO::AIO::pipe2 function.
204 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
205 constants.
206 - added support for O_TMPFILE and O_PATH constants.
207 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
208 consdtants, whether they can be sensibly used or not.
209 - use NO_INIT where applicable.
210 - update libecb.
211 - added stability canary support.
212 - updated linux super magic table to 4.3.3.
213
2144.32 Wed Feb 11 20:32:11 CET 2015
215 - replace off_t by STRLEN where appropriate, should not result in
216 user-visible changes.
217 - update ecb.h for C11 compatibility.
218
2194.31 Tue Jun 3 03:29:27 CEST 2014
220 - work around more 5.20 bugs. backwards compatibility my ass.
221
2224.3 Fri Apr 11 06:22:38 CEST 2014
223 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
224 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
225 in 5.18. What's so attractive about giving a shit about backwards
226 compatibility - I will never understand.
227
2284.2 Sat Jan 25 01:13:14 CET 2014
229 - aio_group could corrupt memory because it didn't restore
230 the stack after req_submit.

239 - avoid endless loop in fiemap with some XFS files.
240 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
241 and call rename/rmdir instead of renameat/unlinkat.
242
2434.18 Thu Oct 11 07:01:26 CEST 2012
244 - fix unintended xthread_create by intentionalising it :)
245
2464.17 Thu Oct 11 05:19:47 CEST 2012
247 - rename aio_fallocate to aio_allocate, to match documentation.
248 - add list of linux fsid values to aio_statvfs docs.
249 - work around a bug in btrfs' FIEMAP ioctl implementation.
250 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
251 as per unix spec.
252
2534.16 Tue Aug 14 05:39:03 CEST 2012
254 - aio_statvfs was wromgly marked for wd emulation, causing
255 it to malfunction for paths.
256 - fix a crash in aio_fiemap, when used on ranges without any
257 extents.
258 - work around linux kernel bug (at least in 3.2): kernel might
259 trash fiemap input arguments.
260 - work around linux kernel bug (at least in 3.2): kernel does not
261 set FIEMAP_EXTENT_LAST on last segment.
262 - work around linux kernel bug (at least in 3.2): kernel silently
263 truncates segment count if a file.
264 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
265 to quick overview.

271
2724.15 Tue Apr 10 06:59:00 CEST 2012
273 - always include linux/types.h for fiemap, for compatibility to
274 ancient systems (Paul Howarth).
275 - experimental support for IO::AIO::splice and ::tee (no aio_...).
276 - provide SEEK_HOLE and SEEK_DATA, if available.
277 - work around (again!) an immensely stupid bug in RHEL, defining
278 autoconf macros in linux system headers (analysed by Paul Howarth).
279
2804.14 Sat Apr 7 02:45:18 CEST 2012
281 - fix stat structure usage on windows, which caused bogus stat results.
