11 50
51 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
52
534.76 Tue Jul 27 20:45:01 CEST 2021
54 - add autoconf test for siginfo_t, which is, of course, not
55 available on windows (reported by Peter Petky).
56 - disable syscalls on solaris, as perl seems to provide an
57 incompatible syscall prototype that clashes with sys/syscall.h.
58 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
59 MAP_UNINITIALIZED.
60
614.75 Wed Dec 30 08:44:55 CET 2020
62 - removed leftover debug output from treescan.
63 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
64 FSCONFIG_*, MOUNT_ATTR_* constants.
65
664.74 Tue Dec 29 16:19:28 CET 2020
67 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
68 - rework bin/treescan to avoid recursion. This fixes two bugs
69 where a deep directory traversal or a lot of command line
70 arguments could cause it to crash.
71 - added (but not documented) open_tree, AT_* and move_mount flags.
72 - support defining syscall numbers in gendef0.
73
744.73 Fri Dec 4 02:08:37 CET 2020
75 - def0.h was not uptodate, running into musl problems
76 (reported by B Fraser).
77 - IO::AIO::splice and IO::AIO::tee didn't properly return
78 64 bit values.
79 - added IO::AIO::accept4.
80 - add various F_SEAL related fcntl constants.
81 - removed experimental marker for fdlimit functions.
82 - fiemap now includes the last segment even if it overflows
83 the end offset, which is arguably the correct behaviour.
84
854.72 Wed Apr 3 04:56:03 CEST 2019
86 - (libeio) if fd 0 is available do not use it for aio_wd, as it
87 collides with IO::AIO::CWD.
88 - added IO::AIO::memfd_create.
89 - correctly include <sys/uio.h> in the vmsplice test.
90 - reduce codesize by ~7% on amd64 by declaring more functions
91 as noinline.
92 - documentation fixes and updates.
93 - experimental and undocumented preliminary support for synchronous statx.
94
954.71 Sun Mar 10 13:09:26 CET 2019
96 - due to an error in the linux manpages, the configure tests
97 for readahead, sync_file_range, splice etc. failed. This has been fixed.
98
994.7 Mon Mar 4 11:28:13 CET 2019
100 - majorly speed up scandir for the very special case of a non-POSIX
101 filesystem that nevertheless reports valid dt_type information.
102 The only known filesystem of this type is currently btrfs, which
103 didn't get it's act together to implement POSIX semantics in all
104 these years, and I am tired of waiting.
105 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
106 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
107 were detected by autoconf.
108
1094.6 Sat Aug 25 21:58:36 CEST 2018
110 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
111 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
112 but only st_gen on openbsd because they compiled their perl without support
113 for birthtimes).
114 - fix madvise and munlock to properly support negative offsets.
115 - allocate fd for the aio_close at boot time, to guarantee it working
116 later, rather than calling abort when it fails. also avoids
117 close-on-exec race issues after module load.
118 - #undef utime on win32, maybe this helps some reports of utime hangs.
119 - minor doc improvements.
120 - minor configure cleanups.
121 - use $Config{perllibs} instead of libs for configure. might help people
122 who didn't install all perl dependencies (might break things as well).
123
1244.54 Tue Aug 14 13:54:48 CEST 2018
125 - include sys/mkdev.h or sys/sysmacros.h if available.
126 - further tweaks to configure invocation for systems requiring --rpath.
127 - no longer rely on custom paths on win32 platforms.
128 - try to work around buggy PAGESIZE macro on solaris.
129
1304.53 Tue Aug 14 11:27:50 CEST 2018
131 - add $Config{libs} to LIBS for configure, to work around systems
132 with broken library dependencies (... openbsd).
133
1344.52 Sun Aug 12 08:09:45 CEST 2018
135 - config.h.in was missing in distribution.
136
1374.51 Sun Aug 12 07:24:14 CEST 2018
138 - complete rework of the autoconf framework: IO::AIO now uses its own
139 config.h, separate from libeio, and tries to test the actual perl
140 environment, not the standard system environment.
141 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
142 stat functions.
143 - removed non-portable C++ syntax from eio.c.
144 - try to fix readdir tests on cygwin spuriously failing.
145
1464.5 Wed Aug 1 00:23:55 CEST 2018
147 - aio_mtouch touch all pages as requested, not just the first page in most cases.
148 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
149 and MREMAP_FIXED.
150 - add O_ACCMODE.
151 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
152
1534.4 Tue Feb 20 07:54:12 CET 2018
154 - new aio_slurp request.
155 - add (experimental) IO::AIO::eventfd and timerfd* function.
156 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
157 - point out that aio_copy overwrites existing files.
158 - removed filesystem magic number table from aio_statvfs docs as
159 statvfs doesn't actually return this info at all (statfs does).
160 - add a bunch of (mostly linux-specific) constants for use in ioctls
161 (see aio_ioctl docs).
162 - treescan now has a proper manpage and useful --help output.
163 - new option --sync in treescan, to sync everything in a subtree.
164 - changed default for aio_msync flags to MSYNC_SYNC.
165 - document offset/length behaviour of mprotect/madvise.
166 - support linux's renameat2 (via aio_rename2).
167 - add aio_rename2, an aio_rename with flags.
168 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
169 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
170 - (libeio) use posix_close if available.
171 - (libeio) internal close() calls no longer disturb errno.
172 - add IO:AIO::FALLOC_FL_UNSHARE.
173 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
174 and better eventfd detection.
175
1764.34 Sun May 1 19:18:24 CEST 2016
177 - def0.h was not properly generated during previous release, causing
178 compile errors on various platforms.
179 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
180 - removed duplicate definition of MAP_HUGETLB, that was found due to
181 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
182 - added (untested!) aio_fcntl, aio_ioctl requests.
183 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
184 as manpages-dev originally claimed.
185
1864.33 Mon Jan 18 12:50:10 CET 2016
187 - add IO::AIO::pipe2 function.
188 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
189 constants.
190 - added support for O_TMPFILE and O_PATH constants.
191 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
192 consdtants, whether they can be sensibly used or not.
193 - use NO_INIT where applicable.
194 - update libecb.
195 - added stability canary support.
196 - updated linux super magic table to 4.3.3.
197
1984.32 Wed Feb 11 20:32:11 CET 2015
199 - replace off_t by STRLEN where appropriate, should not result in
200 user-visible changes.
201 - update ecb.h for C11 compatibility.
202
2034.31 Tue Jun 3 03:29:27 CEST 2014
204 - work around more 5.20 bugs. backwards compatibility my ass.
205
2064.3 Fri Apr 11 06:22:38 CEST 2014
207 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
208 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
209 in 5.18. What's so attractive about giving a shit about backwards
210 compatibility - I will never understand.
211
2124.2 Sat Jan 25 01:13:14 CET 2014
213 - aio_group could corrupt memory because it didn't restore
214 the stack after req_submit.
215 - be more careful on (e.g. permission) errors in bin/treescan.
216 - work around changes in ExtUtils::MakeMaker.
217 - (libeio) implement aio_realpath for win32.
218 - (xthread) work around compile time bugs in ptw32.
219 - added IO::AIO::pipesize.
220 - (libecb) insignificant update.
221
2224.19 Sun Jan 6 12:47:26 CET 2013
223 - avoid endless loop in fiemap with some XFS files.
224 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
225 and call rename/rmdir instead of renameat/unlinkat.
226
2274.18 Thu Oct 11 07:01:26 CEST 2012
228 - fix unintended xthread_create by intentionalising it :)
229
2304.17 Thu Oct 11 05:19:47 CEST 2012
231 - rename aio_fallocate to aio_allocate, to match documentation.
232 - add list of linux fsid values to aio_statvfs docs.
233 - work around a bug in btrfs' FIEMAP ioctl implementation.
234 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
235 as per unix spec.
236
2374.16 Tue Aug 14 05:39:03 CEST 2012
238 - aio_statvfs was wromgly marked for wd emulation, causing
239 it to malfunction for paths.
240 - fix a crash in aio_fiemap, when used on ranges without any
241 extents.
242 - work around linux kernel bug (at least in 3.2): kernel might
243 trash fiemap input arguments.
244 - work around linux kernel bug (at least in 3.2): kernel does not
245 set FIEMAP_EXTENT_LAST on last segment.
246 - work around linux kernel bug (at least in 3.2): kernel silently
247 truncates segment count if a file.
248 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
249 to quick overview.
250 - splice can corrupt data.
251 - (libeio) remove pread/pwrite emulation.
252 - do not grow mmaped scalars in aio_read.
253 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
254 - provide pread/pwrite for win32, making it link again on native win32.
255
2564.15 Tue Apr 10 06:59:00 CEST 2012
257 - always include linux/types.h for fiemap, for compatibility to
258 ancient systems (Paul Howarth).
259 - experimental support for IO::AIO::splice and ::tee (no aio_...).
260 - provide SEEK_HOLE and SEEK_DATA, if available.
261 - work around (again!) an immensely stupid bug in RHEL, defining
262 autoconf macros in linux system headers (analysed by Paul Howarth).
263
2644.14 Sat Apr 7 02:45:18 CEST 2012
265 - fix stat structure usage on windows, which caused bogus stat results.
266 - (libeio) make readahead emulation behave more like actual readahead by never failing.
267 - new request aio_seek.
268 - new request aio_fiemap.
269 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
270
2714.12 Fri Dec 30 08:51:25 CET 2011
272 - realpath would return a random value if the name was too long,
273 instead of -1.
274 - port to c89.
275
2764.11 Mon Oct 10 00:24:11 CEST 2011
277 - libeio didn't compile on !linux (Paul Howarth).
278
2794.1 Sun Oct 9 10:24:11 CEST 2011
280 - IO::AIO did access uninitialised memory on unsuccessful stats.
281 - (libeio) added syncfs syscall wrapper.
282 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
283 - (libeio) support multiple indepenent working directories.
284 - applied speling corrections by Nicholas Bamber.
285 - tune treescan #threads and #outstanding requests a bit.
286 - reduce the number of file descriptors in use at any one time
287 in treescan, to avoid running out of them (and using too much ram).
288 - take advantage of working directoriy abstractions
289 in aio_scandir and treescan.
290 - reduce compiled size by ~10% by not inlining some key functionality.
291 - added --progress switch to treescan.
292
2934.0 Mon Jul 18 05:01:10 CEST 2011
294 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
295 see FORK BEHAVIOUR in manpage for details.
296 - passes testsuite on win32 now and may actually work
297 (activestate 5.10.1 / MSVC6, YMMV).
298 - (libeio) fix a deadlock where a wakeup signal could be missed when
299 a timeout occured at the same time.
300 - (libeio) added realpath.
301 - (libeio) added fallocate.
302 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
303 - (libeio) do not acquire any locks when forking.
304 - (libeio) use fewer time() syscalls when waiting for new requests.
305
3063.93 Wed Jun 29 23:44:18 CEST 2011
307 - ECB.H WAS MISSING.
308
3093.92 Wed Jun 29 14:45:41 CEST 2011
310 - ecb.h was missing.
311
3123.91 Wed Jun 29 13:24:42 CEST 2011
313 - (libeio) work around a Linux (and likely FreeBSD and other
314 kernels) bug where sendfile would not transfer all the requested
315 bytes on large transfers, using a heuristic.
316 - buggy sendfile caused aio_move/copy to sometimes fail for big
317 files (fortunately it checks that the whole file has been
318 transferred...)
319 - use libecb for higher performance and higher portability.
320 - (libeio) disable sendfile on darwin, it's too broken.
321 - disable fork tests on !linux, as only linux supports mixing
322 pthread and fork in perl.
323 - document the fact that fork doesn't work anymore when using
324 this module, on anything !GNU/Linux.
325 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
326 run on a 0.1MHz cpu. Or so.
327
3283.9 Fri May 27 02:43:47 CEST 2011
329 - (libeio) fix memory corruption in aio_readdirx for the flags
330 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.

335 - use nonstandard but maybe-working-on-bsd fork technique.
336 - support a max_idle value of 0.
337 - support setting of idle timeout value (IO::AIO::idle_timeout).
338
3393.72 Fri Feb 11 04:25:38 CET 2011
340 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
341 - aio_mknod always used a dev_t value of 0.
342 - new treescan option: --grep.
343 - add more S_IF macros, and major/minor/makedev "macros".
344
3453.71 Thu Dec 30 08:18:46 CET 2010
346 - the numerical result value passed to callbacks did not stringify
347 correctly, due to internal reuse and failure to reset the sv flags.
348 - actually test for posix_[mf]advise, as at least uClibc defines
349 _POSIX_ADVISORY_INFO without actually having any of the required
350 funcitonality. ugh.
351
3523.7 Mon Nov 1 23:00:34 CET 2010
353 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
354 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
355 - document the sad state of affairs w.r.t. pthread on many bsds.
356 - do not enable mmap on systems without _POSIX_MAPPED_FILES
357 (openbsd 4.8).
358 - do not leak memory in IO::AIO::mmap when the scalar already
359 had string-data.
12 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-documented 360 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
13 them. 361 them.
362 - cache the result IV, for a minor speedup in the common case.
363 - croak when an mmapped-scalar changes location, to detect
364 user-errors better.
365 - fix aio_readlink prototype.
14 366
153.65 Wed Mar 31 02:45:05 CEST 2010 3673.65 Wed Mar 31 02:45:05 CEST 2010
16 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not 368 - 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 369 cut off long pathnames in aio_readlink (based on patch by
18 Rasmus Andersson). 370 Rasmus Andersson).
