11 40
41 - add various F_SEAL related fcntl constants.
42
434.72 Wed Apr 3 04:56:03 CEST 2019
44 - (libeio) if fd 0 is available do not use it for aio_wd, as it
45 collides with IO::AIO::CWD.
46 - added IO::AIO::memfd_create.
47 - correctly include <sys/uio.h> in the vmsplice test.
48 - reduce codesize by ~7% on amd64 by declaring more functions
49 as noinline.
50 - documentation fixes and updates.
51 - experimental and undocumented preliminary support for synchronous statx.
52
534.71 Sun Mar 10 13:09:26 CET 2019
54 - due to an error in the linux manpages, the configure tests
55 for readahead, sync_file_range, splice etc. failed. This has been fixed.
56
574.7 Mon Mar 4 11:28:13 CET 2019
58 - majorly speed up scandir for the very special case of a non-POSIX
59 filesystem that nevertheless reports valid dt_type information.
60 The only known filesystem of this type is currently btrfs, which
61 didn't get it's act together to implement POSIX semantics in all
62 these years, and I am tired of waiting.
63 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
64 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
65 were detected by autoconf.
66
674.6 Sat Aug 25 21:58:36 CEST 2018
68 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
69 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
70 but only st_gen on openbsd because they compiled their perl without support
71 for birthtimes).
72 - fix madvise and munlock to properly support negative offsets.
73 - allocate fd for the aio_close at boot time, to guarantee it working
74 later, rather than calling abort when it fails. also avoids
75 close-on-exec race issues after module load.
76 - #undef utime on win32, maybe this helps some reports of utime hangs.
77 - minor doc improvements.
78 - minor configure cleanups.
79 - use $Config{perllibs} instead of libs for configure. might help people
80 who didn't install all perl dependencies (might break things as well).
81
824.54 Tue Aug 14 13:54:48 CEST 2018
83 - include sys/mkdev.h or sys/sysmacros.h if available.
84 - further tweaks to configure invocation for systems requiring --rpath.
85 - no longer rely on custom paths on win32 platforms.
86 - try to work around buggy PAGESIZE macro on solaris.
87
884.53 Tue Aug 14 11:27:50 CEST 2018
89 - add $Config{libs} to LIBS for configure, to work around systems
90 with broken library dependencies (... openbsd).
91
924.52 Sun Aug 12 08:09:45 CEST 2018
93 - config.h.in was missing in distribution.
94
954.51 Sun Aug 12 07:24:14 CEST 2018
96 - complete rework of the autoconf framework: IO::AIO now uses its own
97 config.h, separate from libeio, and tries to test the actual perl
98 environment, not the standard system environment.
99 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
100 stat functions.
101 - removed non-portable C++ syntax from eio.c.
102 - try to fix readdir tests on cygwin spuriously failing.
103
1044.5 Wed Aug 1 00:23:55 CEST 2018
105 - aio_mtouch touch all pages as requested, not just the first page in most cases.
106 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
107 and MREMAP_FIXED.
108 - add O_ACCMODE.
109 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
110
1114.4 Tue Feb 20 07:54:12 CET 2018
112 - new aio_slurp request.
113 - add (experimental) IO::AIO::eventfd and timerfd* function.
114 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
115 - point out that aio_copy overwrites existing files.
116 - removed filesystem magic number table from aio_statvfs docs as
117 statvfs doesn't actually return this info at all (statfs does).
118 - add a bunch of (mostly linux-specific) constants for use in ioctls
119 (see aio_ioctl docs).
120 - treescan now has a proper manpage and useful --help output.
121 - new option --sync in treescan, to sync everything in a subtree.
122 - changed default for aio_msync flags to MSYNC_SYNC.
123 - document offset/length behaviour of mprotect/madvise.
124 - support linux's renameat2 (via aio_rename2).
125 - add aio_rename2, an aio_rename with flags.
126 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
127 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
128 - (libeio) use posix_close if available.
129 - (libeio) internal close() calls no longer disturb errno.
130 - add IO:AIO::FALLOC_FL_UNSHARE.
131 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
132 and better eventfd detection.
133
1344.34 Sun May 1 19:18:24 CEST 2016
135 - def0.h was not properly generated during previous release, causing
136 compile errors on various platforms.
137 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
138 - removed duplicate definition of MAP_HUGETLB, that was found due to
139 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
140 - added (untested!) aio_fcntl, aio_ioctl requests.
141 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
142 as manpages-dev originally claimed.
143
1444.33 Mon Jan 18 12:50:10 CET 2016
145 - add IO::AIO::pipe2 function.
146 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
147 constants.
148 - added support for O_TMPFILE and O_PATH constants.
149 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
150 consdtants, whether they can be sensibly used or not.
151 - use NO_INIT where applicable.
152 - update libecb.
153 - added stability canary support.
154 - updated linux super magic table to 4.3.3.
155
1564.32 Wed Feb 11 20:32:11 CET 2015
157 - replace off_t by STRLEN where appropriate, should not result in
158 user-visible changes.
159 - update ecb.h for C11 compatibility.
160
1614.31 Tue Jun 3 03:29:27 CEST 2014
162 - work around more 5.20 bugs. backwards compatibility my ass.
163
1644.3 Fri Apr 11 06:22:38 CEST 2014
165 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
166 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
167 in 5.18. What's so attractive about giving a shit about backwards
168 compatibility - I will never understand.
169
1704.2 Sat Jan 25 01:13:14 CET 2014
171 - aio_group could corrupt memory because it didn't restore
172 the stack after req_submit.
173 - be more careful on (e.g. permission) errors in bin/treescan.
174 - work around changes in ExtUtils::MakeMaker.
175 - (libeio) implement aio_realpath for win32.
176 - (xthread) work around compile time bugs in ptw32.
177 - added IO::AIO::pipesize.
178 - (libecb) insignificant update.
179
1804.19 Sun Jan 6 12:47:26 CET 2013
181 - avoid endless loop in fiemap with some XFS files.
182 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
183 and call rename/rmdir instead of renameat/unlinkat.
184
1854.18 Thu Oct 11 07:01:26 CEST 2012
186 - fix unintended xthread_create by intentionalising it :)
187
1884.17 Thu Oct 11 05:19:47 CEST 2012
189 - rename aio_fallocate to aio_allocate, to match documentation.
190 - add list of linux fsid values to aio_statvfs docs.
191 - work around a bug in btrfs' FIEMAP ioctl implementation.
192 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
193 as per unix spec.
194
1954.16 Tue Aug 14 05:39:03 CEST 2012
196 - aio_statvfs was wromgly marked for wd emulation, causing
197 it to malfunction for paths.
198 - fix a crash in aio_fiemap, when used on ranges without any
199 extents.
200 - work around linux kernel bug (at least in 3.2): kernel might
201 trash fiemap input arguments.
202 - work around linux kernel bug (at least in 3.2): kernel does not
203 set FIEMAP_EXTENT_LAST on last segment.
204 - work around linux kernel bug (at least in 3.2): kernel silently
205 truncates segment count if a file.
206 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
207 to quick overview.
208 - splice can corrupt data.
209 - (libeio) remove pread/pwrite emulation.
210 - do not grow mmaped scalars in aio_read.

213
2144.15 Tue Apr 10 06:59:00 CEST 2012
215 - always include linux/types.h for fiemap, for compatibility to
216 ancient systems (Paul Howarth).
217 - experimental support for IO::AIO::splice and ::tee (no aio_...).
218 - provide SEEK_HOLE and SEEK_DATA, if available.
219 - work around (again!) an immensely stupid bug in RHEL, defining
220 autoconf macros in linux system headers (analysed by Paul Howarth).
221
2224.14 Sat Apr 7 02:45:18 CEST 2012
12 - fix stat structure usage on windows, which caused bogus stat results. 223 - fix stat structure usage on windows, which caused bogus stat results.
