49
50 - work around a bug in musl w.r.t to O_SEARCH and use EIO_O_PATH instead,
51 vertifying the semantics against the subset of O_PATH and O_SEARCH
52 (based on a report by Steve Dondley).
53 - aio_copy now tries to preallocate the destination file.
54 - fexecve configure test used the wrong pĆ¼ointer type (patch by Paul Howarth).
55
564.80 Sat 01 Apr 2023 04:13:37 CEST
57 - remove long obsolete "paths must be absolute" text in aio_open/stat
58 descriptions.
59 - another workaround for the low-quality musl libc.
60 - test for umount seperately, as it is more portable.
61 - some low-quality posix attempts (openbsd, osx) declare the availability
62 of fexecve but then don't even bother to implemnent a stub.
63
644.79 Sun 25 Sep 2022 18:25:53 CEST
65 - the autoconf result of the mount check was not used, so it failed to
66 compile on most systems (reported by crackoff@tutanota.com).
67 - work around fedora not having a working C compiler setup by design
68 (reported by Paul Howarth).
69
704.78 Tue 06 Sep 2022 12:54:43 CEST
71 - add IO::AIO::mount and IO::AIO::umount.
72 - add a bunch of symbols from sys/mount.h.
73
744.77 Mon 05 Sep 2022 02:03:38 CEST
75 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
76 - add fexecve.
77 - add lots of missing functions to @EXPORT_OK.
78
794.76 Tue Jul 27 20:45:01 CEST 2021
80 - add autoconf test for siginfo_t, which is, of course, not
81 available on windows (reported by Peter Petky).
82 - disable syscalls on solaris, as perl seems to provide an
83 incompatible syscall prototype that clashes with sys/syscall.h.
84 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
85 MAP_UNINITIALIZED.
86
874.75 Wed Dec 30 08:44:55 CET 2020
88 - removed leftover debug output from treescan.
89 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
90 FSCONFIG_*, MOUNT_ATTR_* constants.
91
924.74 Tue Dec 29 16:19:28 CET 2020
93 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
94 - rework bin/treescan to avoid recursion. This fixes two bugs
95 where a deep directory traversal or a lot of command line
96 arguments could cause it to crash.
97 - added (but not documented) open_tree, AT_* and move_mount flags.
98 - support defining syscall numbers in gendef0.
99
1004.73 Fri Dec 4 02:08:37 CET 2020
101 - def0.h was not uptodate, running into musl problems
102 (reported by B Fraser).
103 - IO::AIO::splice and IO::AIO::tee didn't properly return
104 64 bit values.
105 - added IO::AIO::accept4.
106 - add various F_SEAL related fcntl constants.
107 - removed experimental marker for fdlimit functions.
108 - fiemap now includes the last segment even if it overflows
109 the end offset, which is arguably the correct behaviour.
110
1114.72 Wed Apr 3 04:56:03 CEST 2019
112 - (libeio) if fd 0 is available do not use it for aio_wd, as it
113 collides with IO::AIO::CWD.
114 - added IO::AIO::memfd_create.
115 - correctly include <sys/uio.h> in the vmsplice test.
116 - reduce codesize by ~7% on amd64 by declaring more functions
117 as noinline.
118 - documentation fixes and updates.
119 - experimental and undocumented preliminary support for synchronous statx.
120
1214.71 Sun Mar 10 13:09:26 CET 2019
122 - due to an error in the linux manpages, the configure tests
123 for readahead, sync_file_range, splice etc. failed. This has been fixed.
124
1254.7 Mon Mar 4 11:28:13 CET 2019
126 - majorly speed up scandir for the very special case of a non-POSIX
127 filesystem that nevertheless reports valid dt_type information.
128 The only known filesystem of this type is currently btrfs, which
129 didn't get it's act together to implement POSIX semantics in all
130 these years, and I am tired of waiting.
131 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
132 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
133 were detected by autoconf.
134
1354.6 Sat Aug 25 21:58:36 CEST 2018
136 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
137 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
138 but only st_gen on openbsd because they compiled their perl without support
139 for birthtimes).
140 - fix madvise and munlock to properly support negative offsets.
141 - allocate fd for the aio_close at boot time, to guarantee it working
142 later, rather than calling abort when it fails. also avoids
143 close-on-exec race issues after module load.
144 - #undef utime on win32, maybe this helps some reports of utime hangs.
145 - minor doc improvements.
146 - minor configure cleanups.
147 - use $Config{perllibs} instead of libs for configure. might help people
148 who didn't install all perl dependencies (might break things as well).
149
1504.54 Tue Aug 14 13:54:48 CEST 2018
151 - include sys/mkdev.h or sys/sysmacros.h if available.
152 - further tweaks to configure invocation for systems requiring --rpath.
153 - no longer rely on custom paths on win32 platforms.
154 - try to work around buggy PAGESIZE macro on solaris.
155
1564.53 Tue Aug 14 11:27:50 CEST 2018
157 - add $Config{libs} to LIBS for configure, to work around systems
158 with broken library dependencies (... openbsd).
159
1604.52 Sun Aug 12 08:09:45 CEST 2018
161 - config.h.in was missing in distribution.
162
1634.51 Sun Aug 12 07:24:14 CEST 2018
164 - complete rework of the autoconf framework: IO::AIO now uses its own
165 config.h, separate from libeio, and tries to test the actual perl
166 environment, not the standard system environment.
167 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
168 stat functions.
169 - removed non-portable C++ syntax from eio.c.
170 - try to fix readdir tests on cygwin spuriously failing.
171
1724.5 Wed Aug 1 00:23:55 CEST 2018
173 - aio_mtouch touch all pages as requested, not just the first page in most cases.
174 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
175 and MREMAP_FIXED.
176 - add O_ACCMODE.
177 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
178
1794.4 Tue Feb 20 07:54:12 CET 2018
180 - new aio_slurp request.
181 - add (experimental) IO::AIO::eventfd and timerfd* function.
182 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
183 - point out that aio_copy overwrites existing files.
184 - removed filesystem magic number table from aio_statvfs docs as
185 statvfs doesn't actually return this info at all (statfs does).
186 - add a bunch of (mostly linux-specific) constants for use in ioctls
187 (see aio_ioctl docs).
188 - treescan now has a proper manpage and useful --help output.
189 - new option --sync in treescan, to sync everything in a subtree.
190 - changed default for aio_msync flags to MSYNC_SYNC.
191 - document offset/length behaviour of mprotect/madvise.
192 - support linux's renameat2 (via aio_rename2).
193 - add aio_rename2, an aio_rename with flags.
194 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
195 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
196 - (libeio) use posix_close if available.
197 - (libeio) internal close() calls no longer disturb errno.
198 - add IO:AIO::FALLOC_FL_UNSHARE.
199 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
200 and better eventfd detection.
201
2024.34 Sun May 1 19:18:24 CEST 2016
203 - def0.h was not properly generated during previous release, causing
204 compile errors on various platforms.
205 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
206 - removed duplicate definition of MAP_HUGETLB, that was found due to
207 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
208 - added (untested!) aio_fcntl, aio_ioctl requests.
209 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
210 as manpages-dev originally claimed.
211
2124.33 Mon Jan 18 12:50:10 CET 2016
213 - add IO::AIO::pipe2 function.
214 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
215 constants.
216 - added support for O_TMPFILE and O_PATH constants.
217 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
218 consdtants, whether they can be sensibly used or not.
219 - use NO_INIT where applicable.
220 - update libecb.
221 - added stability canary support.
222 - updated linux super magic table to 4.3.3.
223
2244.32 Wed Feb 11 20:32:11 CET 2015
225 - replace off_t by STRLEN where appropriate, should not result in
226 user-visible changes.
227 - update ecb.h for C11 compatibility.
228
2294.31 Tue Jun 3 03:29:27 CEST 2014
230 - work around more 5.20 bugs. backwards compatibility my ass.
231
2324.3 Fri Apr 11 06:22:38 CEST 2014
233 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
234 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
235 in 5.18. What's so attractive about giving a shit about backwards
236 compatibility - I will never understand.
237
2384.2 Sat Jan 25 01:13:14 CET 2014
239 - aio_group could corrupt memory because it didn't restore
240 the stack after req_submit.
241 - be more careful on (e.g. permission) errors in bin/treescan.
242 - work around changes in ExtUtils::MakeMaker.
243 - (libeio) implement aio_realpath for win32.
244 - (xthread) work around compile time bugs in ptw32.
245 - added IO::AIO::pipesize.
246 - (libecb) insignificant update.
247
2484.19 Sun Jan 6 12:47:26 CET 2013
249 - avoid endless loop in fiemap with some XFS files.
250 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
251 and call rename/rmdir instead of renameat/unlinkat.
252
2534.18 Thu Oct 11 07:01:26 CEST 2012
254 - fix unintended xthread_create by intentionalising it :)
255
2564.17 Thu Oct 11 05:19:47 CEST 2012
257 - rename aio_fallocate to aio_allocate, to match documentation.
258 - add list of linux fsid values to aio_statvfs docs.
259 - work around a bug in btrfs' FIEMAP ioctl implementation.
260 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
261 as per unix spec.
262
2634.16 Tue Aug 14 05:39:03 CEST 2012
264 - aio_statvfs was wromgly marked for wd emulation, causing
265 it to malfunction for paths.
266 - fix a crash in aio_fiemap, when used on ranges without any
267 extents.
268 - work around linux kernel bug (at least in 3.2): kernel might
269 trash fiemap input arguments.
270 - work around linux kernel bug (at least in 3.2): kernel does not
271 set FIEMAP_EXTENT_LAST on last segment.
272 - work around linux kernel bug (at least in 3.2): kernel silently
273 truncates segment count if a file.
274 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
275 to quick overview.
276 - splice can corrupt data.
277 - (libeio) remove pread/pwrite emulation.
278 - do not grow mmaped scalars in aio_read.
279 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
280 - provide pread/pwrite for win32, making it link again on native win32.
281
2824.15 Tue Apr 10 06:59:00 CEST 2012
283 - always include linux/types.h for fiemap, for compatibility to
284 ancient systems (Paul Howarth).
285 - experimental support for IO::AIO::splice and ::tee (no aio_...).
286 - provide SEEK_HOLE and SEEK_DATA, if available.
287 - work around (again!) an immensely stupid bug in RHEL, defining
288 autoconf macros in linux system headers (analysed by Paul Howarth).
289
2904.14 Sat Apr 7 02:45:18 CEST 2012
291 - fix stat structure usage on windows, which caused bogus stat results.
292 - (libeio) make readahead emulation behave more like actual readahead by never failing.
293 - new request aio_seek.
294 - new request aio_fiemap.
295 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
296
2974.12 Fri Dec 30 08:51:25 CET 2011
298 - realpath would return a random value if the name was too long,
299 instead of -1.
300 - port to c89.
301
3024.11 Mon Oct 10 00:24:11 CEST 2011
303 - libeio didn't compile on !linux (Paul Howarth).
304
3054.1 Sun Oct 9 10:24:11 CEST 2011
306 - IO::AIO did access uninitialised memory on unsuccessful stats.
307 - (libeio) added syncfs syscall wrapper.
308 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
309 - (libeio) support multiple indepenent working directories.
310 - applied speling corrections by Nicholas Bamber.
311 - tune treescan #threads and #outstanding requests a bit.
312 - reduce the number of file descriptors in use at any one time
313 in treescan, to avoid running out of them (and using too much ram).
314 - take advantage of working directoriy abstractions
315 in aio_scandir and treescan.
316 - reduce compiled size by ~10% by not inlining some key functionality.
317 - added --progress switch to treescan.
318
3194.0 Mon Jul 18 05:01:10 CEST 2011
320 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
321 see FORK BEHAVIOUR in manpage for details.
322 - passes testsuite on win32 now and may actually work
323 (activestate 5.10.1 / MSVC6, YMMV).
324 - (libeio) fix a deadlock where a wakeup signal could be missed when
325 a timeout occured at the same time.
326 - (libeio) added realpath.
327 - (libeio) added fallocate.
328 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
329 - (libeio) do not acquire any locks when forking.
330 - (libeio) use fewer time() syscalls when waiting for new requests.
331
3323.93 Wed Jun 29 23:44:18 CEST 2011
333 - ECB.H WAS MISSING.
334
3353.92 Wed Jun 29 14:45:41 CEST 2011
336 - ecb.h was missing.
337
3383.91 Wed Jun 29 13:24:42 CEST 2011
339 - (libeio) work around a Linux (and likely FreeBSD and other
340 kernels) bug where sendfile would not transfer all the requested
341 bytes on large transfers, using a heuristic.
342 - buggy sendfile caused aio_move/copy to sometimes fail for big
343 files (fortunately it checks that the whole file has been
344 transferred...)
345 - use libecb for higher performance and higher portability.
346 - (libeio) disable sendfile on darwin, it's too broken.
347 - disable fork tests on !linux, as only linux supports mixing
348 pthread and fork in perl.
349 - document the fact that fork doesn't work anymore when using
350 this module, on anything !GNU/Linux.
351 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
352 run on a 0.1MHz cpu. Or so.
353
3543.9 Fri May 27 02:43:47 CEST 2011
355 - (libeio) fix memory corruption in aio_readdirx for the flags
356 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
357 - add lots of newer POSIX and GNU/Linux-specific open
358 flags.
359
3603.8 Sun Mar 27 12:25:33 CEST 2011
361 - use nonstandard but maybe-working-on-bsd fork technique.
362 - support a max_idle value of 0.
363 - support setting of idle timeout value (IO::AIO::idle_timeout).
364
3653.72 Fri Feb 11 04:25:38 CET 2011
366 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
367 - aio_mknod always used a dev_t value of 0.
368 - new treescan option: --grep.
369 - add more S_IF macros, and major/minor/makedev "macros".
370
3713.71 Thu Dec 30 08:18:46 CET 2010
372 - the numerical result value passed to callbacks did not stringify
373 correctly, due to internal reuse and failure to reset the sv flags.
374 - actually test for posix_[mf]advise, as at least uClibc defines
375 _POSIX_ADVISORY_INFO without actually having any of the required
376 funcitonality. ugh.
377
3783.7 Mon Nov 1 23:00:34 CET 2010
379 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
380 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
381 - document the sad state of affairs w.r.t. pthread on many bsds.
382 - do not enable mmap on systems without _POSIX_MAPPED_FILES
383 (openbsd 4.8).
384 - do not leak memory in IO::AIO::mmap when the scalar already
385 had string-data.
386 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
387 them.
388 - cache the result IV, for a minor speedup in the common case.
389 - croak when an mmapped-scalar changes location, to detect
390 user-errors better.
391 - fix aio_readlink prototype.
392
3933.65 Wed Mar 31 02:45:05 CEST 2010
394 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
395 cut off long pathnames in aio_readlink (based on patch by
396 Rasmus Andersson).
397 - a double fork partially killed the event pipe (great testcase
398 by dormando). affects IO::AIO, BDB and Async::Interrupt.
399 - suck steve's dick and rename our symbols to avoid colliding
400 with nonstandard identifier spam on the broken os x pseudo-os.
401 affects IO::AIO and BDB.
402
4033.6 Mon Jan 11 00:43:39 CET 2010
404 - (libeio) more fixes for the freebsd/apple sendfile - broken by
405 manpage standards, but apparently correct accoridng to actual
