494.80 Sat 01 Apr 2023 04:13:37 CEST
50 - remove long obsolete "paths must be absolute" text in aio_open/stat
51 descriptions.
52 - another workaround for the low-quality musl libc.
53 - test for umount seperately, as it is more portable.
54 - some low-quality posix attempts (openbsd, osx) declare the availability
55 of fexecve but then don't even bother to implemnent a stub.
56
574.79 Sun 25 Sep 2022 18:25:53 CEST
58 - the autoconf result of the mount check was not used, so it failed to
59 compile on most systems (reported by crackoff@tutanota.com).
60 - work around fedora not having a working C compiler setup by design
61 (reported by Paul Howarth).
62
634.78 Tue 06 Sep 2022 12:54:43 CEST
64 - add IO::AIO::mount and IO::AIO::umount.
65 - add a bunch of symbols from sys/mount.h.
66
674.77 Mon 05 Sep 2022 02:03:38 CEST
68 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
69 - add fexecve.
70 - add lots of missing functions to @EXPORT_OK.
71
724.76 Tue Jul 27 20:45:01 CEST 2021
73 - add autoconf test for siginfo_t, which is, of course, not
74 available on windows (reported by Peter Petky).
75 - disable syscalls on solaris, as perl seems to provide an
76 incompatible syscall prototype that clashes with sys/syscall.h.
77 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
78 MAP_UNINITIALIZED.
79
804.75 Wed Dec 30 08:44:55 CET 2020
81 - removed leftover debug output from treescan.
82 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
83 FSCONFIG_*, MOUNT_ATTR_* constants.
84
854.74 Tue Dec 29 16:19:28 CET 2020
86 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
87 - rework bin/treescan to avoid recursion. This fixes two bugs
88 where a deep directory traversal or a lot of command line
89 arguments could cause it to crash.
90 - added (but not documented) open_tree, AT_* and move_mount flags.
91 - support defining syscall numbers in gendef0.
92
934.73 Fri Dec 4 02:08:37 CET 2020
94 - def0.h was not uptodate, running into musl problems
95 (reported by B Fraser).
96 - IO::AIO::splice and IO::AIO::tee didn't properly return
97 64 bit values.
98 - added IO::AIO::accept4.
99 - add various F_SEAL related fcntl constants.
100 - removed experimental marker for fdlimit functions.
101 - fiemap now includes the last segment even if it overflows
102 the end offset, which is arguably the correct behaviour.
103
1044.72 Wed Apr 3 04:56:03 CEST 2019
105 - (libeio) if fd 0 is available do not use it for aio_wd, as it
106 collides with IO::AIO::CWD.
107 - added IO::AIO::memfd_create.
108 - correctly include <sys/uio.h> in the vmsplice test.
109 - reduce codesize by ~7% on amd64 by declaring more functions
110 as noinline.
111 - documentation fixes and updates.
112 - experimental and undocumented preliminary support for synchronous statx.
113
1144.71 Sun Mar 10 13:09:26 CET 2019
115 - due to an error in the linux manpages, the configure tests
116 for readahead, sync_file_range, splice etc. failed. This has been fixed.
117
1184.7 Mon Mar 4 11:28:13 CET 2019
119 - majorly speed up scandir for the very special case of a non-POSIX
120 filesystem that nevertheless reports valid dt_type information.
121 The only known filesystem of this type is currently btrfs, which
122 didn't get it's act together to implement POSIX semantics in all
123 these years, and I am tired of waiting.
124 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
125 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
126 were detected by autoconf.
127
1284.6 Sat Aug 25 21:58:36 CEST 2018
129 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
130 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
131 but only st_gen on openbsd because they compiled their perl without support
132 for birthtimes).
133 - fix madvise and munlock to properly support negative offsets.
134 - allocate fd for the aio_close at boot time, to guarantee it working
135 later, rather than calling abort when it fails. also avoids
136 close-on-exec race issues after module load.
137 - #undef utime on win32, maybe this helps some reports of utime hangs.
138 - minor doc improvements.
139 - minor configure cleanups.
140 - use $Config{perllibs} instead of libs for configure. might help people
141 who didn't install all perl dependencies (might break things as well).
142
1434.54 Tue Aug 14 13:54:48 CEST 2018
144 - include sys/mkdev.h or sys/sysmacros.h if available.
145 - further tweaks to configure invocation for systems requiring --rpath.
146 - no longer rely on custom paths on win32 platforms.
147 - try to work around buggy PAGESIZE macro on solaris.
148
1494.53 Tue Aug 14 11:27:50 CEST 2018
150 - add $Config{libs} to LIBS for configure, to work around systems
151 with broken library dependencies (... openbsd).
152
1534.52 Sun Aug 12 08:09:45 CEST 2018
154 - config.h.in was missing in distribution.
155
1564.51 Sun Aug 12 07:24:14 CEST 2018
157 - complete rework of the autoconf framework: IO::AIO now uses its own
158 config.h, separate from libeio, and tries to test the actual perl
159 environment, not the standard system environment.
160 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
161 stat functions.
162 - removed non-portable C++ syntax from eio.c.
163 - try to fix readdir tests on cygwin spuriously failing.
164
1654.5 Wed Aug 1 00:23:55 CEST 2018
166 - aio_mtouch touch all pages as requested, not just the first page in most cases.
167 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
168 and MREMAP_FIXED.
169 - add O_ACCMODE.
170 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
171
1724.4 Tue Feb 20 07:54:12 CET 2018
173 - new aio_slurp request.
174 - add (experimental) IO::AIO::eventfd and timerfd* function.
175 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
176 - point out that aio_copy overwrites existing files.
177 - removed filesystem magic number table from aio_statvfs docs as
178 statvfs doesn't actually return this info at all (statfs does).
179 - add a bunch of (mostly linux-specific) constants for use in ioctls
180 (see aio_ioctl docs).
181 - treescan now has a proper manpage and useful --help output.
182 - new option --sync in treescan, to sync everything in a subtree.
183 - changed default for aio_msync flags to MSYNC_SYNC.
184 - document offset/length behaviour of mprotect/madvise.
185 - support linux's renameat2 (via aio_rename2).
186 - add aio_rename2, an aio_rename with flags.
187 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
188 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
189 - (libeio) use posix_close if available.
190 - (libeio) internal close() calls no longer disturb errno.
191 - add IO:AIO::FALLOC_FL_UNSHARE.
192 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
193 and better eventfd detection.
194
1954.34 Sun May 1 19:18:24 CEST 2016
196 - def0.h was not properly generated during previous release, causing
197 compile errors on various platforms.
198 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
199 - removed duplicate definition of MAP_HUGETLB, that was found due to
200 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
201 - added (untested!) aio_fcntl, aio_ioctl requests.
202 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
203 as manpages-dev originally claimed.
204
2054.33 Mon Jan 18 12:50:10 CET 2016
206 - add IO::AIO::pipe2 function.
207 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
208 constants.
209 - added support for O_TMPFILE and O_PATH constants.
210 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
211 consdtants, whether they can be sensibly used or not.
212 - use NO_INIT where applicable.
213 - update libecb.
214 - added stability canary support.
215 - updated linux super magic table to 4.3.3.
216
2174.32 Wed Feb 11 20:32:11 CET 2015
218 - replace off_t by STRLEN where appropriate, should not result in
219 user-visible changes.
220 - update ecb.h for C11 compatibility.
221
2224.31 Tue Jun 3 03:29:27 CEST 2014
223 - work around more 5.20 bugs. backwards compatibility my ass.
224
2254.3 Fri Apr 11 06:22:38 CEST 2014
226 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
227 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
228 in 5.18. What's so attractive about giving a shit about backwards
229 compatibility - I will never understand.
230
2314.2 Sat Jan 25 01:13:14 CET 2014
232 - aio_group could corrupt memory because it didn't restore
233 the stack after req_submit.
234 - be more careful on (e.g. permission) errors in bin/treescan.
235 - work around changes in ExtUtils::MakeMaker.
236 - (libeio) implement aio_realpath for win32.
237 - (xthread) work around compile time bugs in ptw32.
238 - added IO::AIO::pipesize.
239 - (libecb) insignificant update.
240
2414.19 Sun Jan 6 12:47:26 CET 2013
242 - avoid endless loop in fiemap with some XFS files.
243 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
244 and call rename/rmdir instead of renameat/unlinkat.
245
2464.18 Thu Oct 11 07:01:26 CEST 2012
247 - fix unintended xthread_create by intentionalising it :)
248
2494.17 Thu Oct 11 05:19:47 CEST 2012
250 - rename aio_fallocate to aio_allocate, to match documentation.
251 - add list of linux fsid values to aio_statvfs docs.
252 - work around a bug in btrfs' FIEMAP ioctl implementation.
253 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
254 as per unix spec.
255
2564.16 Tue Aug 14 05:39:03 CEST 2012
257 - aio_statvfs was wromgly marked for wd emulation, causing
258 it to malfunction for paths.
259 - fix a crash in aio_fiemap, when used on ranges without any
260 extents.
261 - work around linux kernel bug (at least in 3.2): kernel might
262 trash fiemap input arguments.
263 - work around linux kernel bug (at least in 3.2): kernel does not
264 set FIEMAP_EXTENT_LAST on last segment.
265 - work around linux kernel bug (at least in 3.2): kernel silently
266 truncates segment count if a file.
267 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
268 to quick overview.
269 - splice can corrupt data.
270 - (libeio) remove pread/pwrite emulation.
271 - do not grow mmaped scalars in aio_read.

274
2754.15 Tue Apr 10 06:59:00 CEST 2012
276 - always include linux/types.h for fiemap, for compatibility to
277 ancient systems (Paul Howarth).
278 - experimental support for IO::AIO::splice and ::tee (no aio_...).
279 - provide SEEK_HOLE and SEEK_DATA, if available.
280 - work around (again!) an immensely stupid bug in RHEL, defining
281 autoconf macros in linux system headers (analysed by Paul Howarth).
282
2834.14 Sat Apr 7 02:45:18 CEST 2012
284 - fix stat structure usage on windows, which caused bogus stat results.

292 instead of -1.
293 - port to c89.
294
2954.11 Mon Oct 10 00:24:11 CEST 2011
296 - libeio didn't compile on !linux (Paul Howarth).
297
2984.1 Sun Oct 9 10:24:11 CEST 2011
299 - IO::AIO did access uninitialised memory on unsuccessful stats.
300 - (libeio) added syncfs syscall wrapper.
301 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
302 - (libeio) support multiple indepenent working directories.
303 - applied speling corrections by Nicholas Bamber.
304 - tune treescan #threads and #outstanding requests a bit.
305 - reduce the number of file descriptors in use at any one time
306 in treescan, to avoid running out of them (and using too much ram).
307 - take advantage of working directoriy abstractions
308 in aio_scandir and treescan.
309 - reduce compiled size by ~10% by not inlining some key functionality.
310 - added --progress switch to treescan.
311
3124.0 Mon Jul 18 05:01:10 CEST 2011
313 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
314 see FORK BEHAVIOUR in manpage for details.
315 - passes testsuite on win32 now and may actually work
316 (activestate 5.10.1 / MSVC6, YMMV).
317 - (libeio) fix a deadlock where a wakeup signal could be missed when
318 a timeout occured at the same time.
319 - (libeio) added realpath.
320 - (libeio) added fallocate.
321 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
322 - (libeio) do not acquire any locks when forking.
323 - (libeio) use fewer time() syscalls when waiting for new requests.
324
3253.93 Wed Jun 29 23:44:18 CEST 2011
326 - ECB.H WAS MISSING.
327
3283.92 Wed Jun 29 14:45:41 CEST 2011
329 - ecb.h was missing.
330
3313.91 Wed Jun 29 13:24:42 CEST 2011
332 - (libeio) work around a Linux (and likely FreeBSD and other
333 kernels) bug where sendfile would not transfer all the requested
334 bytes on large transfers, using a heuristic.
335 - buggy sendfile caused aio_move/copy to sometimes fail for big
336 files (fortunately it checks that the whole file has been
337 transferred...)
338 - use libecb for higher performance and higher portability.
339 - (libeio) disable sendfile on darwin, it's too broken.
340 - disable fork tests on !linux, as only linux supports mixing
341 pthread and fork in perl.
342 - document the fact that fork doesn't work anymore when using
343 this module, on anything !GNU/Linux.
344 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
345 run on a 0.1MHz cpu. Or so.
346
3473.9 Fri May 27 02:43:47 CEST 2011
348 - (libeio) fix memory corruption in aio_readdirx for the flags

13 - use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock. 359 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
360 - aio_mknod always used a dev_t value of 0.
14 - new treescan option: --grep. 361 - new treescan option: --grep.
362 - add more S_IF macros, and major/minor/makedev "macros".
15 363
163.71 Thu Dec 30 08:18:46 CET 2010 3643.71 Thu Dec 30 08:18:46 CET 2010
17 - the numerical result value passed to callbacks did not stringify 365 - the numerical result value passed to callbacks did not stringify
18 correctly, due to internal reuse and failure to reset the sv flags. 366 correctly, due to internal reuse and failure to reset the sv flags.
19 - actually test for posix_[mf]advise, as at least uClibc defines 367 - actually test for posix_[mf]advise, as at least uClibc defines
