40 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
41 - point out that aio_copy overwrites existing files.
42 - removed filesystem magic number table from aio_statvfs docs as
43 statvfs doesn't actually return this info at all (statfs does).
44 - add a bunch of (mostly linux-specific) constants for use in ioctls
45 (see aio_ioctl docs).
46 - treescan now has a proper manpage and useful --help output.

58 and better eventfd detection.
59
604.34 Sun May 1 19:18:24 CEST 2016
61 - def0.h was not properly generated during previous release, causing
62 compile errors on various platforms.
63 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
64 - removed duplicate definition of MAP_HUGETLB, that was found due to
65 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
66 - added (untested!) aio_fcntl, aio_ioctl requests.
67 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
68 as manpages-dev originally claimed.
69
704.33 Mon Jan 18 12:50:10 CET 2016
71 - add IO::AIO::pipe2 function.
72 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
73 constants.
74 - added support for O_TMPFILE and O_PATH constants.
75 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK

86
874.31 Tue Jun 3 03:29:27 CEST 2014
88 - work around more 5.20 bugs. backwards compatibility my ass.
89
904.3 Fri Apr 11 06:22:38 CEST 2014
91 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
92 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
93 in 5.18. What's so attractive about giving a shit about backwards
94 compatibility - I will never understand.
95
964.2 Sat Jan 25 01:13:14 CET 2014
97 - aio_group could corrupt memory because it didn't restore
98 the stack after req_submit.
99 - be more careful on (e.g. permission) errors in bin/treescan.

107 - avoid endless loop in fiemap with some XFS files.
108 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]

110
1114.18 Thu Oct 11 07:01:26 CEST 2012
112 - fix unintended xthread_create by intentionalising it :)
113
1144.17 Thu Oct 11 05:19:47 CEST 2012
115 - rename aio_fallocate to aio_allocate, to match documentation.
116 - add list of linux fsid values to aio_statvfs docs.
117 - work around a bug in btrfs' FIEMAP ioctl implementation.
118 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
119 as per unix spec.
120
1214.16 Tue Aug 14 05:39:03 CEST 2012
122 - aio_statvfs was wromgly marked for wd emulation, causing
123 it to malfunction for paths.
124 - fix a crash in aio_fiemap, when used on ranges without any
125 extents.
126 - work around linux kernel bug (at least in 3.2): kernel might
127 trash fiemap input arguments.
128 - work around linux kernel bug (at least in 3.2): kernel does not
129 set FIEMAP_EXTENT_LAST on last segment.
130 - work around linux kernel bug (at least in 3.2): kernel silently
131 truncates segment count if a file.
132 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
133 to quick overview.
134 - splice can corrupt data.
135 - (libeio) remove pread/pwrite emulation.
136 - do not grow mmaped scalars in aio_read.

139
1404.15 Tue Apr 10 06:59:00 CEST 2012
141 - always include linux/types.h for fiemap, for compatibility to
142 ancient systems (Paul Howarth).
143 - experimental support for IO::AIO::splice and ::tee (no aio_...).
144 - provide SEEK_HOLE and SEEK_DATA, if available.
145 - work around (again!) an immensely stupid bug in RHEL, defining
146 autoconf macros in linux system headers (analysed by Paul Howarth).
147
1484.14 Sat Apr 7 02:45:18 CEST 2012
149 - fix stat structure usage on windows, which caused bogus stat results.
150 - (libeio) make readahead emulation behave more like actual readahead by never failing.
151 - new request aio_seek.
152 - new request aio_fiemap.
153 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
154
1554.12 Fri Dec 30 08:51:25 CET 2011
156 - realpath would return a random value if the name was too long,
157 instead of -1.
158 - port to c89.
159
1604.11 Mon Oct 10 00:24:11 CEST 2011
161 - libeio didn't compile on !linux (Paul Howarth).
162
1634.1 Sun Oct 9 10:24:11 CEST 2011
164 - IO::AIO did access uninitialised memory on unsuccessful stats.
165 - (libeio) added syncfs syscall wrapper.
166 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
167 - (libeio) support multiple indepenent working directories.
168 - applied speling corrections by Nicholas Bamber.
169 - tune treescan #threads and #outstanding requests a bit.
170 - reduce the number of file descriptors in use at any one time
171 in treescan, to avoid running out of them (and using too much ram).
172 - take advantage of working directoriy abstractions
173 in aio_scandir and treescan.
174 - reduce compiled size by ~10% by not inlining some key functionality.
175 - added --progress switch to treescan.
176
1774.0 Mon Jul 18 05:01:10 CEST 2011
178 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
179 see FORK BEHAVIOUR in manpage for details.
180 - passes testsuite on win32 now and may actually work
181 (activestate 5.10.1 / MSVC6, YMMV).
182 - (libeio) fix a deadlock where a wakeup signal could be missed when
183 a timeout occured at the same time.
184 - (libeio) added realpath.
185 - (libeio) added fallocate.
186 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
187 - (libeio) do not acquire any locks when forking.
188 - (libeio) use fewer time() syscalls when waiting for new requests.
189
1903.93 Wed Jun 29 23:44:18 CEST 2011
191 - ECB.H WAS MISSING.
192
1933.92 Wed Jun 29 14:45:41 CEST 2011
194 - ecb.h was missing.
195
1963.91 Wed Jun 29 13:24:42 CEST 2011
197 - (libeio) work around a Linux (and likely FreeBSD and other
198 kernels) bug where sendfile would not transfer all the requested
199 bytes on large transfers, using a heuristic.
200 - buggy sendfile caused aio_move/copy to sometimes fail for big
201 files (fortunately it checks that the whole file has been
202 transferred...)
203 - use libecb for higher performance and higher portability.
204 - (libeio) disable sendfile on darwin, it's too broken.
205 - disable fork tests on !linux, as only linux supports mixing
206 pthread and fork in perl.
207 - document the fact that fork doesn't work anymore when using
208 this module, on anything !GNU/Linux.
209 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
210 run on a 0.1MHz cpu. Or so.
211
2123.9 Fri May 27 02:43:47 CEST 2011
213 - (libeio) fix memory corruption in aio_readdirx for the flags
214 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
215 - add lots of newer POSIX and GNU/Linux-specific open
216 flags.
217
2183.8 Sun Mar 27 12:25:33 CEST 2011
219 - use nonstandard but maybe-working-on-bsd fork technique.
220 - support a max_idle value of 0.
221 - support setting of idle timeout value (IO::AIO::idle_timeout).
222
2233.72 Fri Feb 11 04:25:38 CET 2011
224 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
225 - aio_mknod always used a dev_t value of 0.
226 - new treescan option: --grep.
227 - add more S_IF macros, and major/minor/makedev "macros".
228
2293.71 Thu Dec 30 08:18:46 CET 2010
230 - the numerical result value passed to callbacks did not stringify
231 correctly, due to internal reuse and failure to reset the sv flags.
232 - actually test for posix_[mf]advise, as at least uClibc defines
233 _POSIX_ADVISORY_INFO without actually having any of the required
234 funcitonality. ugh.
235
2363.7 Mon Nov 1 23:00:34 CET 2010
237 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
238 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
239 - document the sad state of affairs w.r.t. pthread on many bsds.
240 - do not enable mmap on systems without _POSIX_MAPPED_FILES
241 (openbsd 4.8).
242 - do not leak memory in IO::AIO::mmap when the scalar already
243 had string-data.
244 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
245 them.
246 - cache the result IV, for a minor speedup in the common case.
247 - croak when an mmapped-scalar changes location, to detect
248 user-errors better.
249 - fix aio_readlink prototype.
250
2513.65 Wed Mar 31 02:45:05 CEST 2010
252 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
253 cut off long pathnames in aio_readlink (based on patch by
254 Rasmus Andersson).
255 - a double fork partially killed the event pipe (great testcase
256 by dormando). affects IO::AIO, BDB and Async::Interrupt.
257 - suck steve's dick and rename our symbols to avoid colliding
258 with nonstandard identifier spam on the broken os x pseudo-os.
259 affects IO::AIO and BDB.
260
2613.6 Mon Jan 11 00:43:39 CET 2010
262 - (libeio) more fixes for the freebsd/apple sendfile - broken by
263 manpage standards, but apparently correct accoridng to actual
264 kernel sources.
265 - add IO::AIO::mmap/munmap support.
266 - add IO::AIO::m(un)lockall support.
267 - clean up manpage.
268
2693.5 Thu Jan 7 21:25:04 CET 2010
270 - (liebio) fix freebsd sendfile (Vanilla Hsu).
271 - (libeio) also fix darwin sendfile that suffered from a similar bug.
272 - add aio_statvfs as interface to statvfs/fstatvfs.
273 - work around buggy symlink() on cygwin in the testsuite.
274 - wtf. freebsd-8.0 actually passes the testsuite! I knew
275 they could implement fork and semaphores one day! cheers!
276
2773.4 Sat Jan 2 15:13:04 CET 2010
278 - (libeio) max_poll_time was not properly converted to ticks.
279 - clarify cancel_subs description.
280 - IO::AIO::sendfile did not actually return the return value
281 from the sendfile call.
282 - implement aio_msync, aio_mtouch.
283 - (libeio) tentatively support darwin in sendfile.
284
2853.31 Thu Nov 12 02:14:29 CET 2009
286 - fix result status documentation of aio_copy, aio_move.
287 - speed up object creation considerably by avoiding
288 hash lookups.
289
2903.3 Wed Aug 5 13:52:58 CEST 2009
291 - use common::sense.
292 - use common schmorp.h header.
293 - allow integers (file descriptors) in addition to file handles.
294 - take advantage of linux' eventfd (but it seems slower on smp?).
295 - use poll not select on posix platforms.
296
2973.261 Wed Jul 1 10:11:51 CEST 2009
298 - more 0S X workarounds (patch by Tokuhiro Matsuno).
299
3003.26 Tue Jun 30 09:33:26 CEST 2009
301 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
302 try to work around this horribly broken OS in a somewhat hackish
303 way. might help other os's too.
304
3053.25 Sat Jun 27 05:18:26 CEST 2009
306 - added IO::AIO::fadvise and IO::AIO::sendfile.
307 - (libeio) replaced quicksort+insertion sort by a tuned radix
308 sort + insertion sort, resulting in comparable runtime (usually
309 faster) to the old version, but without any ill side effects on
310 degenerated (for quicksort) data.
311 - (libeio) correctly sort dirs by inodes if we have perfect type
312 knowledge and DIRS_FIRST is used.
313 - (libeio) internally the wrong DT_* constants were used, but no
314 known system has differing EIO_DT_*/DT_* values, so not an issue.
315 - removed a (harmless) assert that was left over on the code
316 but should not have been.
317 - use more correct types (change IO length from IV to VAL64,
318 which makes a difference on systems without 64 bit perls).
319
3203.23 Sat Jun 13 16:57:58 CEST 2009
321 - fix off-by-one bug in aio_readdir that was introduced in the
322 rushed 3.22 release.
323
3243.22 Sat Jun 13 15:32:40 CEST 2009
325 - speed up readdirx sort algorithm slightly.
326 - bin/treescan was missing from distro tarball.
327
3283.21 Fri Jun 12 18:45:53 CEST 2009
329 - new options --dirs and --files for treescan.
330 - install bin/treescan by default.
331 - (libeio) aio_readdir can now be cancelled while executing.
332 - fix a printf format string for 64 bit systems (could lead
333 to problems on big endian 64 bit systems).
334 - do not use qsort() but our own algorithm: glibc initialises
335 the whole locale and I/O subsystem inside qsort, causing
336 a stack overflow on 32 bit machines. The new sort uses much less
337 stack and is more than twice as fast in typical situations.
338
3393.2 Sun Jun 7 20:30:05 CEST 2009
340 - (libeio) pwrite emulation was even more flawed than intended and did
341 not restore the file offset.
342 - add aio_readdirx, which can return inode and filetype and sort
343 the names in various ways.
344 - unfortunately, utime, chmod, chown on an open file that has just
345 been written can easily block, which caused aio_copy to block the
346 process. no more!
347 - no longer rely on dst path in aio_copy when futime is available.
348
3493.19 Tue Apr 21 22:05:21 CEST 2009
350 - more perl 5.10 workarounds for aio_read and write.
351 - aio_write no longer modifies the sv (if possible).
352 - aio_read now works correctly with magic values.
353
3543.18 Sun Apr 19 21:17:32 CEST 2009
355 - better diagnostics when some aio_* functions get passed an illegal fh.
356 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
357
3583.17 Thu Nov 20 08:45:36 CET 2008
359 - (libeio) added aio_sync_file_range (untested).
360 - add aio_busy to @IO::AIO::AIO_REQ.
361
3623.16 Wed Oct 22 18:28:01 CEST 2008
363 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
364 part to improve portability to perl 5.8 (reported by szymon).
365
3663.15 Mon Oct 13 00:39:55 CEST 2008
367 - automatic removal of feeders was broken.
368 - (libeio) use a more robust method to detect whether a feeder
369 has added something to the group or not.
370
3713.1 Thu Oct 2 13:34:40 CEST 2008
372 - pre-deref the passed callback object, for increased speed
373 and decreased memory usage.
374 - call on_next_submit callback even for aio_group - impact unknown,
375 but seems more correct.
376 - $req->cb now returns the original callback.
377 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
378 requiring a thread switch.
379 - (libeio) status code of aio_futime and aio_utime was always passed 0.
380 - do some other ยต-optimisations.
381
3823.07 Sat Aug 2 16:06:13 CEST 2008
383 - do not include LIBS in autoconf tests.
384
3853.06 Tue Jul 15 12:41:32 CEST 2008
386 - move preadwritelock definition before it's first reference,
387 to make it compile again on broken platforms (they still exist)
388 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
389
3903.05 Thu Jun 19 23:23:52 CEST 2008
391 - work around perl overriding readdir etc. with thread-unsafe
392 (sic!) versions.
393
3943.04 Wed Jun 18 01:35:38 CEST 2008
395 - (libeio) fix eio_mknod, which confused it's arguments.
396 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
397 is stupid.
398 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
399 - (libeio) fix a bug that could potentially cause IO::AIO
400 not to get initialised properly.
401
4023.03 Thu May 29 05:33:30 CEST 2008
403 - (libeio) correctly call pthread_attr_destroy ().
404 - (libeio) work around broken bsd headers once more.
405 - reduce shared library size again by not including wrappers.
406 - max_outstanding could cause poll to enter a busy-waiting loop.
