50
51 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
52
534.76 Tue Jul 27 20:45:01 CEST 2021
54 - add autoconf test for siginfo_t, which is, of course, not
55 available on windows (reported by Peter Petky).
56 - disable syscalls on solaris, as perl seems to provide an
57 incompatible syscall prototype that clashes with sys/syscall.h.
58 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
59 MAP_UNINITIALIZED.
60
614.75 Wed Dec 30 08:44:55 CET 2020
62 - removed leftover debug output from treescan.
63 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
64 FSCONFIG_*, MOUNT_ATTR_* constants.
65
664.74 Tue Dec 29 16:19:28 CET 2020
67 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
68 - rework bin/treescan to avoid recursion. This fixes two bugs
69 where a deep directory traversal or a lot of command line
70 arguments could cause it to crash.
71 - added (but not documented) open_tree, AT_* and move_mount flags.
72 - support defining syscall numbers in gendef0.
73
744.73 Fri Dec 4 02:08:37 CET 2020
75 - def0.h was not uptodate, running into musl problems
76 (reported by B Fraser).
77 - IO::AIO::splice and IO::AIO::tee didn't properly return
78 64 bit values.
79 - added IO::AIO::accept4.
80 - add various F_SEAL related fcntl constants.
81 - removed experimental marker for fdlimit functions.
82 - fiemap now includes the last segment even if it overflows
83 the end offset, which is arguably the correct behaviour.
84
854.72 Wed Apr 3 04:56:03 CEST 2019
86 - (libeio) if fd 0 is available do not use it for aio_wd, as it
87 collides with IO::AIO::CWD.
88 - added IO::AIO::memfd_create.
89 - correctly include <sys/uio.h> in the vmsplice test.
90 - reduce codesize by ~7% on amd64 by declaring more functions
91 as noinline.
92 - documentation fixes and updates.
93 - experimental and undocumented preliminary support for synchronous statx.
94
954.71 Sun Mar 10 13:09:26 CET 2019
96 - due to an error in the linux manpages, the configure tests
97 for readahead, sync_file_range, splice etc. failed. This has been fixed.
98
994.7 Mon Mar 4 11:28:13 CET 2019
100 - majorly speed up scandir for the very special case of a non-POSIX
101 filesystem that nevertheless reports valid dt_type information.
102 The only known filesystem of this type is currently btrfs, which
103 didn't get it's act together to implement POSIX semantics in all
104 these years, and I am tired of waiting.
105 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
106 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
107 were detected by autoconf.
108
1094.6 Sat Aug 25 21:58:36 CEST 2018
110 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
111 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
112 but only st_gen on openbsd because they compiled their perl without support
113 for birthtimes).
114 - fix madvise and munlock to properly support negative offsets.
115 - allocate fd for the aio_close at boot time, to guarantee it working
116 later, rather than calling abort when it fails. also avoids
117 close-on-exec race issues after module load.
118 - #undef utime on win32, maybe this helps some reports of utime hangs.
119 - minor doc improvements.
120 - minor configure cleanups.
121 - use $Config{perllibs} instead of libs for configure. might help people
122 who didn't install all perl dependencies (might break things as well).
123
1244.54 Tue Aug 14 13:54:48 CEST 2018
125 - include sys/mkdev.h or sys/sysmacros.h if available.
126 - further tweaks to configure invocation for systems requiring --rpath.
127 - no longer rely on custom paths on win32 platforms.
128 - try to work around buggy PAGESIZE macro on solaris.
129
1304.53 Tue Aug 14 11:27:50 CEST 2018
131 - add $Config{libs} to LIBS for configure, to work around systems
132 with broken library dependencies (... openbsd).
133
1344.52 Sun Aug 12 08:09:45 CEST 2018
135 - config.h.in was missing in distribution.
136
1374.51 Sun Aug 12 07:24:14 CEST 2018
138 - complete rework of the autoconf framework: IO::AIO now uses its own
139 config.h, separate from libeio, and tries to test the actual perl
140 environment, not the standard system environment.
141 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
142 stat functions.
143 - removed non-portable C++ syntax from eio.c.
144 - try to fix readdir tests on cygwin spuriously failing.
145
1464.5 Wed Aug 1 00:23:55 CEST 2018
147 - aio_mtouch touch all pages as requested, not just the first page in most cases.
148 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
149 and MREMAP_FIXED.
150 - add O_ACCMODE.
151 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
152
1534.4 Tue Feb 20 07:54:12 CET 2018
154 - new aio_slurp request.
155 - add (experimental) IO::AIO::eventfd and timerfd* function.
156 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
157 - point out that aio_copy overwrites existing files.
158 - removed filesystem magic number table from aio_statvfs docs as
159 statvfs doesn't actually return this info at all (statfs does).
160 - add a bunch of (mostly linux-specific) constants for use in ioctls
161 (see aio_ioctl docs).
162 - treescan now has a proper manpage and useful --help output.
163 - new option --sync in treescan, to sync everything in a subtree.
164 - changed default for aio_msync flags to MSYNC_SYNC.
165 - document offset/length behaviour of mprotect/madvise.
166 - support linux's renameat2 (via aio_rename2).
167 - add aio_rename2, an aio_rename with flags.
168 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
169 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
170 - (libeio) use posix_close if available.
171 - (libeio) internal close() calls no longer disturb errno.
172 - add IO:AIO::FALLOC_FL_UNSHARE.
173 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
174 and better eventfd detection.
175
1764.34 Sun May 1 19:18:24 CEST 2016
177 - def0.h was not properly generated during previous release, causing
178 compile errors on various platforms.
179 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
180 - removed duplicate definition of MAP_HUGETLB, that was found due to
181 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
182 - added (untested!) aio_fcntl, aio_ioctl requests.
183 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
184 as manpages-dev originally claimed.
185
1864.33 Mon Jan 18 12:50:10 CET 2016
187 - add IO::AIO::pipe2 function.
188 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
189 constants.
190 - added support for O_TMPFILE and O_PATH constants.
191 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
192 consdtants, whether they can be sensibly used or not.
193 - use NO_INIT where applicable.
194 - update libecb.
195 - added stability canary support.
196 - updated linux super magic table to 4.3.3.
197
1984.32 Wed Feb 11 20:32:11 CET 2015
199 - replace off_t by STRLEN where appropriate, should not result in
200 user-visible changes.
201 - update ecb.h for C11 compatibility.
202
2034.31 Tue Jun 3 03:29:27 CEST 2014
204 - work around more 5.20 bugs. backwards compatibility my ass.
205
2064.3 Fri Apr 11 06:22:38 CEST 2014
207 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
208 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
209 in 5.18. What's so attractive about giving a shit about backwards
210 compatibility - I will never understand.
211
2124.2 Sat Jan 25 01:13:14 CET 2014
213 - aio_group could corrupt memory because it didn't restore
214 the stack after req_submit.
215 - be more careful on (e.g. permission) errors in bin/treescan.
216 - work around changes in ExtUtils::MakeMaker.
217 - (libeio) implement aio_realpath for win32.
218 - (xthread) work around compile time bugs in ptw32.
219 - added IO::AIO::pipesize.
220 - (libecb) insignificant update.
12 221
134.19 Sun Jan 6 12:47:26 CET 2013 2224.19 Sun Jan 6 12:47:26 CET 2013
14 - avoid endless loop in fiemap with some XFS files. 223 - avoid endless loop in fiemap with some XFS files.
15 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."] 224 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
16 and call rename/rmdir instead of renameat/unlinkat. 225 and call rename/rmdir instead of renameat/unlinkat.
