50
514.80 Sat 01 Apr 2023 04:13:37 CEST
52 - remove long obsolete "paths must be absolute" text in aio_open/stat
53 descriptions.
54 - another workaround for the low-quality musl libc.
55 - test for umount seperately, as it is more portable.
56 - some low-quality posix attempts (openbsd, osx) declare the availability
57 of fexecve but then don't even bother to implemnent a stub.
58
594.79 Sun 25 Sep 2022 18:25:53 CEST
60 - the autoconf result of the mount check was not used, so it failed to
61 compile on most systems (reported by crackoff@tutanota.com).
62 - work around fedora not having a working C compiler setup by design
63 (reported by Paul Howarth).
64
654.78 Tue 06 Sep 2022 12:54:43 CEST
66 - add IO::AIO::mount and IO::AIO::umount.
67 - add a bunch of symbols from sys/mount.h.
68
694.77 Mon 05 Sep 2022 02:03:38 CEST
70 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
71 - add fexecve.
72 - add lots of missing functions to @EXPORT_OK.
73
744.76 Tue Jul 27 20:45:01 CEST 2021
75 - add autoconf test for siginfo_t, which is, of course, not
76 available on windows (reported by Peter Petky).
77 - disable syscalls on solaris, as perl seems to provide an
78 incompatible syscall prototype that clashes with sys/syscall.h.
79 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
80 MAP_UNINITIALIZED.
81
824.75 Wed Dec 30 08:44:55 CET 2020
83 - removed leftover debug output from treescan.
84 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
85 FSCONFIG_*, MOUNT_ATTR_* constants.
86
874.74 Tue Dec 29 16:19:28 CET 2020
88 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
89 - rework bin/treescan to avoid recursion. This fixes two bugs
90 where a deep directory traversal or a lot of command line
91 arguments could cause it to crash.
92 - added (but not documented) open_tree, AT_* and move_mount flags.
93 - support defining syscall numbers in gendef0.
94
954.73 Fri Dec 4 02:08:37 CET 2020
96 - def0.h was not uptodate, running into musl problems
97 (reported by B Fraser).
98 - IO::AIO::splice and IO::AIO::tee didn't properly return
99 64 bit values.
100 - added IO::AIO::accept4.
101 - add various F_SEAL related fcntl constants.
102 - removed experimental marker for fdlimit functions.
103 - fiemap now includes the last segment even if it overflows
104 the end offset, which is arguably the correct behaviour.
105
1064.72 Wed Apr 3 04:56:03 CEST 2019
107 - (libeio) if fd 0 is available do not use it for aio_wd, as it
108 collides with IO::AIO::CWD.
109 - added IO::AIO::memfd_create.
110 - correctly include <sys/uio.h> in the vmsplice test.
111 - reduce codesize by ~7% on amd64 by declaring more functions
112 as noinline.
113 - documentation fixes and updates.
114 - experimental and undocumented preliminary support for synchronous statx.
115
1164.71 Sun Mar 10 13:09:26 CET 2019
117 - due to an error in the linux manpages, the configure tests
118 for readahead, sync_file_range, splice etc. failed. This has been fixed.
119
1204.7 Mon Mar 4 11:28:13 CET 2019
121 - majorly speed up scandir for the very special case of a non-POSIX
122 filesystem that nevertheless reports valid dt_type information.
123 The only known filesystem of this type is currently btrfs, which
124 didn't get it's act together to implement POSIX semantics in all
125 these years, and I am tired of waiting.
126 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
127 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
128 were detected by autoconf.
129
1304.6 Sat Aug 25 21:58:36 CEST 2018
131 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
132 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
133 but only st_gen on openbsd because they compiled their perl without support
134 for birthtimes).
135 - fix madvise and munlock to properly support negative offsets.
136 - allocate fd for the aio_close at boot time, to guarantee it working
137 later, rather than calling abort when it fails. also avoids
138 close-on-exec race issues after module load.
139 - #undef utime on win32, maybe this helps some reports of utime hangs.
140 - minor doc improvements.
141 - minor configure cleanups.
142 - use $Config{perllibs} instead of libs for configure. might help people
143 who didn't install all perl dependencies (might break things as well).
144
1454.54 Tue Aug 14 13:54:48 CEST 2018
146 - include sys/mkdev.h or sys/sysmacros.h if available.
147 - further tweaks to configure invocation for systems requiring --rpath.
148 - no longer rely on custom paths on win32 platforms.
149 - try to work around buggy PAGESIZE macro on solaris.
150
1514.53 Tue Aug 14 11:27:50 CEST 2018
152 - add $Config{libs} to LIBS for configure, to work around systems
153 with broken library dependencies (... openbsd).
154
1554.52 Sun Aug 12 08:09:45 CEST 2018
156 - config.h.in was missing in distribution.
157
1584.51 Sun Aug 12 07:24:14 CEST 2018
159 - complete rework of the autoconf framework: IO::AIO now uses its own
160 config.h, separate from libeio, and tries to test the actual perl
161 environment, not the standard system environment.
162 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
163 stat functions.
164 - removed non-portable C++ syntax from eio.c.
165 - try to fix readdir tests on cygwin spuriously failing.
166
1674.5 Wed Aug 1 00:23:55 CEST 2018
168 - aio_mtouch touch all pages as requested, not just the first page in most cases.
169 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
170 and MREMAP_FIXED.
171 - add O_ACCMODE.
172 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
173
1744.4 Tue Feb 20 07:54:12 CET 2018
175 - new aio_slurp request.
176 - add (experimental) IO::AIO::eventfd and timerfd* function.
177 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
178 - point out that aio_copy overwrites existing files.
179 - removed filesystem magic number table from aio_statvfs docs as
180 statvfs doesn't actually return this info at all (statfs does).
181 - add a bunch of (mostly linux-specific) constants for use in ioctls
182 (see aio_ioctl docs).
183 - treescan now has a proper manpage and useful --help output.
184 - new option --sync in treescan, to sync everything in a subtree.
185 - changed default for aio_msync flags to MSYNC_SYNC.
186 - document offset/length behaviour of mprotect/madvise.
187 - support linux's renameat2 (via aio_rename2).
188 - add aio_rename2, an aio_rename with flags.
189 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
190 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
191 - (libeio) use posix_close if available.
192 - (libeio) internal close() calls no longer disturb errno.
193 - add IO:AIO::FALLOC_FL_UNSHARE.
194 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
195 and better eventfd detection.
196
1974.34 Sun May 1 19:18:24 CEST 2016
198 - def0.h was not properly generated during previous release, causing
199 compile errors on various platforms.
200 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
201 - removed duplicate definition of MAP_HUGETLB, that was found due to
202 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
203 - added (untested!) aio_fcntl, aio_ioctl requests.
204 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
205 as manpages-dev originally claimed.
206
2074.33 Mon Jan 18 12:50:10 CET 2016
208 - add IO::AIO::pipe2 function.
209 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
210 constants.
211 - added support for O_TMPFILE and O_PATH constants.
212 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
213 consdtants, whether they can be sensibly used or not.
214 - use NO_INIT where applicable.
215 - update libecb.
216 - added stability canary support.
217 - updated linux super magic table to 4.3.3.
218
2194.32 Wed Feb 11 20:32:11 CET 2015
220 - replace off_t by STRLEN where appropriate, should not result in
221 user-visible changes.
222 - update ecb.h for C11 compatibility.
223
2244.31 Tue Jun 3 03:29:27 CEST 2014
225 - work around more 5.20 bugs. backwards compatibility my ass.
226
2274.3 Fri Apr 11 06:22:38 CEST 2014
228 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
229 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
230 in 5.18. What's so attractive about giving a shit about backwards
231 compatibility - I will never understand.
232
2334.2 Sat Jan 25 01:13:14 CET 2014
234 - aio_group could corrupt memory because it didn't restore
235 the stack after req_submit.
236 - be more careful on (e.g. permission) errors in bin/treescan.
237 - work around changes in ExtUtils::MakeMaker.
238 - (libeio) implement aio_realpath for win32.
239 - (xthread) work around compile time bugs in ptw32.
240 - added IO::AIO::pipesize.
241 - (libecb) insignificant update.
242
2434.19 Sun Jan 6 12:47:26 CET 2013
244 - avoid endless loop in fiemap with some XFS files.
245 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
246 and call rename/rmdir instead of renameat/unlinkat.
247
2484.18 Thu Oct 11 07:01:26 CEST 2012
249 - fix unintended xthread_create by intentionalising it :)
250
2514.17 Thu Oct 11 05:19:47 CEST 2012
252 - rename aio_fallocate to aio_allocate, to match documentation.
253 - add list of linux fsid values to aio_statvfs docs.
254 - work around a bug in btrfs' FIEMAP ioctl implementation.
255 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
256 as per unix spec.
257
2584.16 Tue Aug 14 05:39:03 CEST 2012
259 - aio_statvfs was wromgly marked for wd emulation, causing
260 it to malfunction for paths.
261 - fix a crash in aio_fiemap, when used on ranges without any
262 extents.
263 - work around linux kernel bug (at least in 3.2): kernel might
264 trash fiemap input arguments.
265 - work around linux kernel bug (at least in 3.2): kernel does not
266 set FIEMAP_EXTENT_LAST on last segment.
267 - work around linux kernel bug (at least in 3.2): kernel silently
268 truncates segment count if a file.
269 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
270 to quick overview.
271 - splice can corrupt data.
272 - (libeio) remove pread/pwrite emulation.
273 - do not grow mmaped scalars in aio_read.

276
2774.15 Tue Apr 10 06:59:00 CEST 2012
278 - always include linux/types.h for fiemap, for compatibility to
279 ancient systems (Paul Howarth).
280 - experimental support for IO::AIO::splice and ::tee (no aio_...).
281 - provide SEEK_HOLE and SEEK_DATA, if available.
282 - work around (again!) an immensely stupid bug in RHEL, defining
283 autoconf macros in linux system headers (analysed by Paul Howarth).
284
2854.14 Sat Apr 7 02:45:18 CEST 2012
286 - fix stat structure usage on windows, which caused bogus stat results.
287 - (libeio) make readahead emulation behave more like actual readahead by never failing.

304 - (libeio) support multiple indepenent working directories.
305 - applied speling corrections by Nicholas Bamber.
306 - tune treescan #threads and #outstanding requests a bit.
307 - reduce the number of file descriptors in use at any one time
308 in treescan, to avoid running out of them (and using too much ram).
309 - take advantage of working directoriy abstractions
310 in aio_scandir and treescan.
311 - reduce compiled size by ~10% by not inlining some key functionality.
312 - added --progress switch to treescan.
313
3144.0 Mon Jul 18 05:01:10 CEST 2011
315 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
316 see FORK BEHAVIOUR in manpage for details.
317 - passes testsuite on win32 now and may actually work
318 (activestate 5.10.1 / MSVC6, YMMV).

332
3333.91 Wed Jun 29 13:24:42 CEST 2011
12 - (libeio) work around a Linux (and likely FreeBSD and other 334 - (libeio) work around a Linux (and likely FreeBSD and other
13 kernels) bug where sendfile would not transfer all the requested 335 kernels) bug where sendfile would not transfer all the requested
14 bytes on large transfers, using a heuristic. 336 bytes on large transfers, using a heuristic.
15 - buggy sendfile caused aio_move/copy to sometimes fail for big 337 - buggy sendfile caused aio_move/copy to sometimes fail for big
