11 49
50 - aio_copy now tries to preallocate the destination file.
51 - fexecve configure test used the wrong pĆ¼ointer type (patch by Paul Howarth).
52
534.80 Sat 01 Apr 2023 04:13:37 CEST
54 - remove long obsolete "paths must be absolute" text in aio_open/stat
55 descriptions.
56 - another workaround for the low-quality musl libc.
57 - test for umount seperately, as it is more portable.
58 - some low-quality posix attempts (openbsd, osx) declare the availability
59 of fexecve but then don't even bother to implemnent a stub.
60
614.79 Sun 25 Sep 2022 18:25:53 CEST
62 - the autoconf result of the mount check was not used, so it failed to
63 compile on most systems (reported by crackoff@tutanota.com).
64 - work around fedora not having a working C compiler setup by design
65 (reported by Paul Howarth).
66
674.78 Tue 06 Sep 2022 12:54:43 CEST
68 - add IO::AIO::mount and IO::AIO::umount.
69 - add a bunch of symbols from sys/mount.h.
70
714.77 Mon 05 Sep 2022 02:03:38 CEST
72 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
73 - add fexecve.
74 - add lots of missing functions to @EXPORT_OK.
75
764.76 Tue Jul 27 20:45:01 CEST 2021
77 - add autoconf test for siginfo_t, which is, of course, not
78 available on windows (reported by Peter Petky).
79 - disable syscalls on solaris, as perl seems to provide an
80 incompatible syscall prototype that clashes with sys/syscall.h.
81 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
82 MAP_UNINITIALIZED.
83
844.75 Wed Dec 30 08:44:55 CET 2020
85 - removed leftover debug output from treescan.
86 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
87 FSCONFIG_*, MOUNT_ATTR_* constants.
88
894.74 Tue Dec 29 16:19:28 CET 2020
90 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
91 - rework bin/treescan to avoid recursion. This fixes two bugs
92 where a deep directory traversal or a lot of command line
93 arguments could cause it to crash.
94 - added (but not documented) open_tree, AT_* and move_mount flags.
95 - support defining syscall numbers in gendef0.
96
974.73 Fri Dec 4 02:08:37 CET 2020
98 - def0.h was not uptodate, running into musl problems
99 (reported by B Fraser).
100 - IO::AIO::splice and IO::AIO::tee didn't properly return
101 64 bit values.
102 - added IO::AIO::accept4.
103 - add various F_SEAL related fcntl constants.
104 - removed experimental marker for fdlimit functions.
105 - fiemap now includes the last segment even if it overflows
106 the end offset, which is arguably the correct behaviour.
107
1084.72 Wed Apr 3 04:56:03 CEST 2019
109 - (libeio) if fd 0 is available do not use it for aio_wd, as it
110 collides with IO::AIO::CWD.
111 - added IO::AIO::memfd_create.
112 - correctly include <sys/uio.h> in the vmsplice test.
113 - reduce codesize by ~7% on amd64 by declaring more functions
114 as noinline.
115 - documentation fixes and updates.
116 - experimental and undocumented preliminary support for synchronous statx.
117
1184.71 Sun Mar 10 13:09:26 CET 2019
119 - due to an error in the linux manpages, the configure tests
120 for readahead, sync_file_range, splice etc. failed. This has been fixed.
121
1224.7 Mon Mar 4 11:28:13 CET 2019
123 - majorly speed up scandir for the very special case of a non-POSIX
124 filesystem that nevertheless reports valid dt_type information.
125 The only known filesystem of this type is currently btrfs, which
126 didn't get it's act together to implement POSIX semantics in all
127 these years, and I am tired of waiting.
128 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
129 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
130 were detected by autoconf.
131
1324.6 Sat Aug 25 21:58:36 CEST 2018
133 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
134 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
135 but only st_gen on openbsd because they compiled their perl without support
136 for birthtimes).
137 - fix madvise and munlock to properly support negative offsets.
138 - allocate fd for the aio_close at boot time, to guarantee it working
139 later, rather than calling abort when it fails. also avoids
140 close-on-exec race issues after module load.
141 - #undef utime on win32, maybe this helps some reports of utime hangs.
142 - minor doc improvements.
143 - minor configure cleanups.
144 - use $Config{perllibs} instead of libs for configure. might help people
145 who didn't install all perl dependencies (might break things as well).
146
1474.54 Tue Aug 14 13:54:48 CEST 2018
148 - include sys/mkdev.h or sys/sysmacros.h if available.
149 - further tweaks to configure invocation for systems requiring --rpath.
150 - no longer rely on custom paths on win32 platforms.
151 - try to work around buggy PAGESIZE macro on solaris.
152
1534.53 Tue Aug 14 11:27:50 CEST 2018
154 - add $Config{libs} to LIBS for configure, to work around systems
155 with broken library dependencies (... openbsd).
156
1574.52 Sun Aug 12 08:09:45 CEST 2018
158 - config.h.in was missing in distribution.
159
1604.51 Sun Aug 12 07:24:14 CEST 2018
161 - complete rework of the autoconf framework: IO::AIO now uses its own
162 config.h, separate from libeio, and tries to test the actual perl
163 environment, not the standard system environment.
164 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
165 stat functions.
166 - removed non-portable C++ syntax from eio.c.
167 - try to fix readdir tests on cygwin spuriously failing.
168
1694.5 Wed Aug 1 00:23:55 CEST 2018
170 - aio_mtouch touch all pages as requested, not just the first page in most cases.
171 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
172 and MREMAP_FIXED.
173 - add O_ACCMODE.
174 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
175
1764.4 Tue Feb 20 07:54:12 CET 2018
177 - new aio_slurp request.
178 - add (experimental) IO::AIO::eventfd and timerfd* function.
179 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
180 - point out that aio_copy overwrites existing files.
181 - removed filesystem magic number table from aio_statvfs docs as
182 statvfs doesn't actually return this info at all (statfs does).
183 - add a bunch of (mostly linux-specific) constants for use in ioctls
184 (see aio_ioctl docs).
185 - treescan now has a proper manpage and useful --help output.
186 - new option --sync in treescan, to sync everything in a subtree.
187 - changed default for aio_msync flags to MSYNC_SYNC.
188 - document offset/length behaviour of mprotect/madvise.
189 - support linux's renameat2 (via aio_rename2).
190 - add aio_rename2, an aio_rename with flags.
191 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
192 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
193 - (libeio) use posix_close if available.
194 - (libeio) internal close() calls no longer disturb errno.
195 - add IO:AIO::FALLOC_FL_UNSHARE.
196 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
197 and better eventfd detection.
198
1994.34 Sun May 1 19:18:24 CEST 2016
200 - def0.h was not properly generated during previous release, causing
201 compile errors on various platforms.
202 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
203 - removed duplicate definition of MAP_HUGETLB, that was found due to
204 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
205 - added (untested!) aio_fcntl, aio_ioctl requests.
206 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
207 as manpages-dev originally claimed.
208
2094.33 Mon Jan 18 12:50:10 CET 2016
210 - add IO::AIO::pipe2 function.
211 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
212 constants.
213 - added support for O_TMPFILE and O_PATH constants.
214 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
215 consdtants, whether they can be sensibly used or not.
216 - use NO_INIT where applicable.
217 - update libecb.
218 - added stability canary support.
219 - updated linux super magic table to 4.3.3.
220
2214.32 Wed Feb 11 20:32:11 CET 2015
222 - replace off_t by STRLEN where appropriate, should not result in
223 user-visible changes.
224 - update ecb.h for C11 compatibility.
225
2264.31 Tue Jun 3 03:29:27 CEST 2014
227 - work around more 5.20 bugs. backwards compatibility my ass.
228
2294.3 Fri Apr 11 06:22:38 CEST 2014
230 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
231 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
232 in 5.18. What's so attractive about giving a shit about backwards
233 compatibility - I will never understand.
234
2354.2 Sat Jan 25 01:13:14 CET 2014
236 - aio_group could corrupt memory because it didn't restore
237 the stack after req_submit.
238 - be more careful on (e.g. permission) errors in bin/treescan.
239 - work around changes in ExtUtils::MakeMaker.
240 - (libeio) implement aio_realpath for win32.
241 - (xthread) work around compile time bugs in ptw32.
242 - added IO::AIO::pipesize.
243 - (libecb) insignificant update.
244
2454.19 Sun Jan 6 12:47:26 CET 2013
246 - avoid endless loop in fiemap with some XFS files.
247 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
248 and call rename/rmdir instead of renameat/unlinkat.
249
2504.18 Thu Oct 11 07:01:26 CEST 2012
251 - fix unintended xthread_create by intentionalising it :)
252
2534.17 Thu Oct 11 05:19:47 CEST 2012
254 - rename aio_fallocate to aio_allocate, to match documentation.
255 - add list of linux fsid values to aio_statvfs docs.
256 - work around a bug in btrfs' FIEMAP ioctl implementation.
257 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
258 as per unix spec.
259
2604.16 Tue Aug 14 05:39:03 CEST 2012
261 - aio_statvfs was wromgly marked for wd emulation, causing
262 it to malfunction for paths.
263 - fix a crash in aio_fiemap, when used on ranges without any
264 extents.
265 - work around linux kernel bug (at least in 3.2): kernel might
266 trash fiemap input arguments.
267 - work around linux kernel bug (at least in 3.2): kernel does not
268 set FIEMAP_EXTENT_LAST on last segment.
269 - work around linux kernel bug (at least in 3.2): kernel silently
270 truncates segment count if a file.
271 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
272 to quick overview.
273 - splice can corrupt data.
274 - (libeio) remove pread/pwrite emulation.
275 - do not grow mmaped scalars in aio_read.

278
2794.15 Tue Apr 10 06:59:00 CEST 2012
280 - always include linux/types.h for fiemap, for compatibility to
281 ancient systems (Paul Howarth).
282 - experimental support for IO::AIO::splice and ::tee (no aio_...).
283 - provide SEEK_HOLE and SEEK_DATA, if available.
284 - work around (again!) an immensely stupid bug in RHEL, defining
285 autoconf macros in linux system headers (analysed by Paul Howarth).
286
2874.14 Sat Apr 7 02:45:18 CEST 2012
288 - fix stat structure usage on windows, which caused bogus stat results.
289 - (libeio) make readahead emulation behave more like actual readahead by never failing.
290 - new request aio_seek.
291 - new request aio_fiemap.
292 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
293
2944.12 Fri Dec 30 08:51:25 CET 2011
295 - realpath would return a random value if the name was too long,
296 instead of -1.
297 - port to c89.
298
2994.11 Mon Oct 10 00:24:11 CEST 2011
300 - libeio didn't compile on !linux (Paul Howarth).
301
3024.1 Sun Oct 9 10:24:11 CEST 2011
303 - IO::AIO did access uninitialised memory on unsuccessful stats.
304 - (libeio) added syncfs syscall wrapper.
305 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
306 - (libeio) support multiple indepenent working directories.
307 - applied speling corrections by Nicholas Bamber.
308 - tune treescan #threads and #outstanding requests a bit.
309 - reduce the number of file descriptors in use at any one time
310 in treescan, to avoid running out of them (and using too much ram).
311 - take advantage of working directoriy abstractions
312 in aio_scandir and treescan.
313 - reduce compiled size by ~10% by not inlining some key functionality.
314 - added --progress switch to treescan.
315
3164.0 Mon Jul 18 05:01:10 CEST 2011
317 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
318 see FORK BEHAVIOUR in manpage for details.
319 - passes testsuite on win32 now and may actually work
320 (activestate 5.10.1 / MSVC6, YMMV).
321 - (libeio) fix a deadlock where a wakeup signal could be missed when
322 a timeout occured at the same time.
323 - (libeio) added realpath.
324 - (libeio) added fallocate.
325 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
326 - (libeio) do not acquire any locks when forking.
327 - (libeio) use fewer time() syscalls when waiting for new requests.
328
3293.93 Wed Jun 29 23:44:18 CEST 2011
330 - ECB.H WAS MISSING.
331
3323.92 Wed Jun 29 14:45:41 CEST 2011
333 - ecb.h was missing.
334
3353.91 Wed Jun 29 13:24:42 CEST 2011
336 - (libeio) work around a Linux (and likely FreeBSD and other
337 kernels) bug where sendfile would not transfer all the requested
338 bytes on large transfers, using a heuristic.
339 - buggy sendfile caused aio_move/copy to sometimes fail for big
340 files (fortunately it checks that the whole file has been
341 transferred...)
342 - use libecb for higher performance and higher portability.
343 - (libeio) disable sendfile on darwin, it's too broken.
344 - disable fork tests on !linux, as only linux supports mixing
345 pthread and fork in perl.
346 - document the fact that fork doesn't work anymore when using
347 this module, on anything !GNU/Linux.
348 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
349 run on a 0.1MHz cpu. Or so.
350
3513.9 Fri May 27 02:43:47 CEST 2011
352 - (libeio) fix memory corruption in aio_readdirx for the flags
353 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.

358 - use nonstandard but maybe-working-on-bsd fork technique.
359 - support a max_idle value of 0.
360 - support setting of idle timeout value (IO::AIO::idle_timeout).
361
3623.72 Fri Feb 11 04:25:38 CET 2011
363 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
364 - aio_mknod always used a dev_t value of 0.
365 - new treescan option: --grep.
366 - add more S_IF macros, and major/minor/makedev "macros".
367
3683.71 Thu Dec 30 08:18:46 CET 2010
369 - the numerical result value passed to callbacks did not stringify
370 correctly, due to internal reuse and failure to reset the sv flags.
371 - actually test for posix_[mf]advise, as at least uClibc defines
372 _POSIX_ADVISORY_INFO without actually having any of the required
373 funcitonality. ugh.
374
3753.7 Mon Nov 1 23:00:34 CET 2010
376 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
377 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
378 - document the sad state of affairs w.r.t. pthread on many bsds.
379 - do not enable mmap on systems without _POSIX_MAPPED_FILES
380 (openbsd 4.8).
381 - do not leak memory in IO::AIO::mmap when the scalar already
382 had string-data.
12 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-documented 383 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
13 them. 384 them.
385 - cache the result IV, for a minor speedup in the common case.
386 - croak when an mmapped-scalar changes location, to detect
387 user-errors better.
388 - fix aio_readlink prototype.
14 389
153.65 Wed Mar 31 02:45:05 CEST 2010 3903.65 Wed Mar 31 02:45:05 CEST 2010
16 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not 391 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
17 cut off long pathnames in aio_readlink (based on patch by 392 cut off long pathnames in aio_readlink (based on patch by
18 Rasmus Andersson). 393 Rasmus Andersson).
