62.0 254.2 Sat Jan 25 01:13:14 CET 2014
26 - aio_group could corrupt memory because it didn't restore
27 the stack after req_submit.

29 - work around changes in ExtUtils::MakeMaker.
30 - (libeio) implement aio_realpath for win32.
31 - (xthread) work around compile time bugs in ptw32.
32 - added IO::AIO::pipesize.
33 - (libecb) insignificant update.
34
354.19 Sun Jan 6 12:47:26 CET 2013
36 - avoid endless loop in fiemap with some XFS files.
37 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
38 and call rename/rmdir instead of renameat/unlinkat.
39
404.18 Thu Oct 11 07:01:26 CEST 2012
41 - fix unintended xthread_create by intentionalising it :)
42
434.17 Thu Oct 11 05:19:47 CEST 2012
44 - rename aio_fallocate to aio_allocate, to match documentation.
45 - add list of linux fsid values to aio_statvfs docs.
46 - work around a bug in btrfs' FIEMAP ioctl implementation.
47 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
48 as per unix spec.
49
504.16 Tue Aug 14 05:39:03 CEST 2012
51 - aio_statvfs was wromgly marked for wd emulation, causing
52 it to malfunction for paths.
53 - fix a crash in aio_fiemap, when used on ranges without any
54 extents.
55 - work around linux kernel bug (at least in 3.2): kernel might
56 trash fiemap input arguments.
57 - work around linux kernel bug (at least in 3.2): kernel does not
58 set FIEMAP_EXTENT_LAST on last segment.
59 - work around linux kernel bug (at least in 3.2): kernel silently
60 truncates segment count if a file.
61 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
62 to quick overview.
63 - splice can corrupt data.
64 - (libeio) remove pread/pwrite emulation.
65 - do not grow mmaped scalars in aio_read.
66 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
67 - provide pread/pwrite for win32, making it link again on native win32.
68
694.15 Tue Apr 10 06:59:00 CEST 2012
70 - always include linux/types.h for fiemap, for compatibility to
71 ancient systems (Paul Howarth).
72 - experimental support for IO::AIO::splice and ::tee (no aio_...).
73 - provide SEEK_HOLE and SEEK_DATA, if available.
74 - work around (again!) an immensely stupid bug in RHEL, defining
75 autoconf macros in linux system headers (analysed by Paul Howarth).
76
774.14 Sat Apr 7 02:45:18 CEST 2012
78 - fix stat structure usage on windows, which caused bogus stat results.
79 - (libeio) make readahead emulation behave more like actual readahead by never failing.
80 - new request aio_seek.
81 - new request aio_fiemap.
82 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
83
844.12 Fri Dec 30 08:51:25 CET 2011
85 - realpath would return a random value if the name was too long,
86 instead of -1.
87 - port to c89.
88
894.11 Mon Oct 10 00:24:11 CEST 2011
90 - libeio didn't compile on !linux (Paul Howarth).
91
924.1 Sun Oct 9 10:24:11 CEST 2011
93 - IO::AIO did access uninitialised memory on unsuccessful stats.
94 - (libeio) added syncfs syscall wrapper.
95 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
96 - (libeio) support multiple indepenent working directories.
97 - applied speling corrections by Nicholas Bamber.
98 - tune treescan #threads and #outstanding requests a bit.
99 - reduce the number of file descriptors in use at any one time
100 in treescan, to avoid running out of them (and using too much ram).
101 - take advantage of working directoriy abstractions
102 in aio_scandir and treescan.
103 - reduce compiled size by ~10% by not inlining some key functionality.
104 - added --progress switch to treescan.
105
1064.0 Mon Jul 18 05:01:10 CEST 2011
107 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
108 see FORK BEHAVIOUR in manpage for details.
109 - passes testsuite on win32 now and may actually work
110 (activestate 5.10.1 / MSVC6, YMMV).
111 - (libeio) fix a deadlock where a wakeup signal could be missed when
112 a timeout occured at the same time.
113 - (libeio) added realpath.
114 - (libeio) added fallocate.
115 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
116 - (libeio) do not acquire any locks when forking.
117 - (libeio) use fewer time() syscalls when waiting for new requests.
118
1193.93 Wed Jun 29 23:44:18 CEST 2011
120 - ECB.H WAS MISSING.
121
1223.92 Wed Jun 29 14:45:41 CEST 2011
123 - ecb.h was missing.
124
1253.91 Wed Jun 29 13:24:42 CEST 2011
126 - (libeio) work around a Linux (and likely FreeBSD and other
127 kernels) bug where sendfile would not transfer all the requested
128 bytes on large transfers, using a heuristic.
129 - buggy sendfile caused aio_move/copy to sometimes fail for big
130 files (fortunately it checks that the whole file has been
131 transferred...)
132 - use libecb for higher performance and higher portability.
133 - (libeio) disable sendfile on darwin, it's too broken.
134 - disable fork tests on !linux, as only linux supports mixing
135 pthread and fork in perl.
136 - document the fact that fork doesn't work anymore when using
137 this module, on anything !GNU/Linux.
138 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
139 run on a 0.1MHz cpu. Or so.
140
1413.9 Fri May 27 02:43:47 CEST 2011
142 - (libeio) fix memory corruption in aio_readdirx for the flags
143 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
144 - add lots of newer POSIX and GNU/Linux-specific open
145 flags.
146
1473.8 Sun Mar 27 12:25:33 CEST 2011
148 - use nonstandard but maybe-working-on-bsd fork technique.
149 - support a max_idle value of 0.
150 - support setting of idle timeout value (IO::AIO::idle_timeout).
151
1523.72 Fri Feb 11 04:25:38 CET 2011
153 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
154 - aio_mknod always used a dev_t value of 0.
155 - new treescan option: --grep.
156 - add more S_IF macros, and major/minor/makedev "macros".
157
1583.71 Thu Dec 30 08:18:46 CET 2010
159 - the numerical result value passed to callbacks did not stringify
160 correctly, due to internal reuse and failure to reset the sv flags.
161 - actually test for posix_[mf]advise, as at least uClibc defines
162 _POSIX_ADVISORY_INFO without actually having any of the required
163 funcitonality. ugh.
164
1653.7 Mon Nov 1 23:00:34 CET 2010
166 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
167 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
168 - document the sad state of affairs w.r.t. pthread on many bsds.
169 - do not enable mmap on systems without _POSIX_MAPPED_FILES
170 (openbsd 4.8).
171 - do not leak memory in IO::AIO::mmap when the scalar already
172 had string-data.
173 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
174 them.
175 - cache the result IV, for a minor speedup in the common case.
176 - croak when an mmapped-scalar changes location, to detect
177 user-errors better.
178 - fix aio_readlink prototype.
179
1803.65 Wed Mar 31 02:45:05 CEST 2010
181 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
182 cut off long pathnames in aio_readlink (based on patch by
183 Rasmus Andersson).
184 - a double fork partially killed the event pipe (great testcase
185 by dormando). affects IO::AIO, BDB and Async::Interrupt.
186 - suck steve's dick and rename our symbols to avoid colliding
187 with nonstandard identifier spam on the broken os x pseudo-os.
188 affects IO::AIO and BDB.
189
1903.6 Mon Jan 11 00:43:39 CET 2010
191 - (libeio) more fixes for the freebsd/apple sendfile - broken by
192 manpage standards, but apparently correct accoridng to actual
193 kernel sources.
194 - add IO::AIO::mmap/munmap support.
195 - add IO::AIO::m(un)lockall support.
196 - clean up manpage.
197
1983.5 Thu Jan 7 21:25:04 CET 2010
199 - (liebio) fix freebsd sendfile (Vanilla Hsu).
200 - (libeio) also fix darwin sendfile that suffered from a similar bug.
201 - add aio_statvfs as interface to statvfs/fstatvfs.
202 - work around buggy symlink() on cygwin in the testsuite.
203 - wtf. freebsd-8.0 actually passes the testsuite! I knew
204 they could implement fork and semaphores one day! cheers!
205
2063.4 Sat Jan 2 15:13:04 CET 2010
207 - (libeio) max_poll_time was not properly converted to ticks.
208 - clarify cancel_subs description.
209 - IO::AIO::sendfile did not actually return the return value
210 from the sendfile call.
211 - implement aio_msync, aio_mtouch.
212 - (libeio) tentatively support darwin in sendfile.
213
2143.31 Thu Nov 12 02:14:29 CET 2009
215 - fix result status documentation of aio_copy, aio_move.
216 - speed up object creation considerably by avoiding
217 hash lookups.
218
2193.3 Wed Aug 5 13:52:58 CEST 2009
220 - use common::sense.
221 - use common schmorp.h header.
222 - allow integers (file descriptors) in addition to file handles.
223 - take advantage of linux' eventfd (but it seems slower on smp?).
224 - use poll not select on posix platforms.
225
2263.261 Wed Jul 1 10:11:51 CEST 2009
227 - more 0S X workarounds (patch by Tokuhiro Matsuno).
228
2293.26 Tue Jun 30 09:33:26 CEST 2009
230 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
231 try to work around this horribly broken OS in a somewhat hackish
232 way. might help other os's too.
233
2343.25 Sat Jun 27 05:18:26 CEST 2009
235 - added IO::AIO::fadvise and IO::AIO::sendfile.
236 - (libeio) replaced quicksort+insertion sort by a tuned radix
237 sort + insertion sort, resulting in comparable runtime (usually
238 faster) to the old version, but without any ill side effects on
239 degenerated (for quicksort) data.
240 - (libeio) correctly sort dirs by inodes if we have perfect type
241 knowledge and DIRS_FIRST is used.
242 - (libeio) internally the wrong DT_* constants were used, but no
243 known system has differing EIO_DT_*/DT_* values, so not an issue.
244 - removed a (harmless) assert that was left over on the code
245 but should not have been.
246 - use more correct types (change IO length from IV to VAL64,
247 which makes a difference on systems without 64 bit perls).
248
2493.23 Sat Jun 13 16:57:58 CEST 2009
250 - fix off-by-one bug in aio_readdir that was introduced in the
251 rushed 3.22 release.
252
2533.22 Sat Jun 13 15:32:40 CEST 2009
254 - speed up readdirx sort algorithm slightly.
255 - bin/treescan was missing from distro tarball.
256
2573.21 Fri Jun 12 18:45:53 CEST 2009
258 - new options --dirs and --files for treescan.
259 - install bin/treescan by default.
260 - (libeio) aio_readdir can now be cancelled while executing.
261 - fix a printf format string for 64 bit systems (could lead
262 to problems on big endian 64 bit systems).
263 - do not use qsort() but our own algorithm: glibc initialises
264 the whole locale and I/O subsystem inside qsort, causing
265 a stack overflow on 32 bit machines. The new sort uses much less
266 stack and is more than twice as fast in typical situations.
267
2683.2 Sun Jun 7 20:30:05 CEST 2009
269 - (libeio) pwrite emulation was even more flawed than intended and did
270 not restore the file offset.
271 - add aio_readdirx, which can return inode and filetype and sort
272 the names in various ways.
273 - unfortunately, utime, chmod, chown on an open file that has just
274 been written can easily block, which caused aio_copy to block the
275 process. no more!
276 - no longer rely on dst path in aio_copy when futime is available.
277
2783.19 Tue Apr 21 22:05:21 CEST 2009
279 - more perl 5.10 workarounds for aio_read and write.
280 - aio_write no longer modifies the sv (if possible).
281 - aio_read now works correctly with magic values.
282
2833.18 Sun Apr 19 21:17:32 CEST 2009
284 - better diagnostics when some aio_* functions get passed an illegal fh.
285 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
286
2873.17 Thu Nov 20 08:45:36 CET 2008
288 - (libeio) added aio_sync_file_range (untested).
289 - add aio_busy to @IO::AIO::AIO_REQ.
290
2913.16 Wed Oct 22 18:28:01 CEST 2008
292 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
293 part to improve portability to perl 5.8 (reported by szymon).
294
2953.15 Mon Oct 13 00:39:55 CEST 2008
296 - automatic removal of feeders was broken.
297 - (libeio) use a more robust method to detect whether a feeder
298 has added something to the group or not.
299
3003.1 Thu Oct 2 13:34:40 CEST 2008
301 - pre-deref the passed callback object, for increased speed
302 and decreased memory usage.
303 - call on_next_submit callback even for aio_group - impact unknown,
304 but seems more correct.
305 - $req->cb now returns the original callback.
306 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
307 requiring a thread switch.
308 - (libeio) status code of aio_futime and aio_utime was always passed 0.
309 - do some other ยต-optimisations.
310
3113.07 Sat Aug 2 16:06:13 CEST 2008
312 - do not include LIBS in autoconf tests.
313
3143.06 Tue Jul 15 12:41:32 CEST 2008
315 - move preadwritelock definition before it's first reference,
316 to make it compile again on broken platforms (they still exist)
317 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
318
3193.05 Thu Jun 19 23:23:52 CEST 2008
320 - work around perl overriding readdir etc. with thread-unsafe
321 (sic!) versions.
322
3233.04 Wed Jun 18 01:35:38 CEST 2008
324 - (libeio) fix eio_mknod, which confused it's arguments.
325 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
326 is stupid.
327 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
328 - (libeio) fix a bug that could potentially cause IO::AIO
329 not to get initialised properly.
330
3313.03 Thu May 29 05:33:30 CEST 2008
332 - (libeio) correctly call pthread_attr_destroy ().
333 - (libeio) work around broken bsd headers once more.
334 - reduce shared library size again by not including wrappers.
335 - max_outstanding could cause poll to enter a busy-waiting loop.
336 - document the new IO::AIO::poll_cb result value.
337
3383.02 Mon May 12 02:32:02 CEST 2008
339 - fix a memory leak on aio_readlink.
340 - bring back working fchmod.
341 - nop and busy now set result to 0.
342 - set errno to ENOMEM when allocation fails.
343
3443.01 Sun May 11 03:07:03 CEST 2008
345 - (libeio) make it compile on systems without readahead or readdir_r.
346 - (libeio) improve configure check for readahead availability.
347 - do not try to link against -lrt.
348 - use a separate configure script for IO::AIO (not the libeio one).
349
3503.0 Sun May 11 00:57:14 CEST 2008
351 - added bin/treescan to the distribution.
352 - switched to using libeio.
353 - LOTS OF INCOMPATIBLE CHANGES:
354 - remove signal functionality, it is not worth the effort.
355 - max_outstanding no longer returns the previous number of requests.
356 - poll_cb no longer returns number of requests.
357
3582.62 Sat Apr 26 13:59:33 CEST 2008
359 - port to solaris perls configured for old posix
360 (analysed by Jost Krieger).
361 - keep a reference to the perl filehandle object in aio_close,
362 so it doesn't get closed prematurely, leading to ugly races.
363
3642.61 Wed Apr 16 18:45:02 CEST 2008
365 - fix treescan output duplication and improve output ordering.
366 also display files given on the commandline.
367 - use a different algorithm for aio_close that is faster
368 and probably has even lower chances of blocking.
369 - do our own stack memory management for threads - linux
370 allocates outrageous amounts of VM (not so bad unless you
371 use mlockall...), which severely limits the number of threads
372 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
373 and 4096 * sizeof (long) (usually this is 16..64k).
374
3752.6 Sun Mar 30 08:28:11 CEST 2008
376 - added aio_sync.
377 - added aio_pathsync.
378 - fix prototypes of (void) functions.
379
3802.51 Sat Oct 6 16:04:54 CEST 2007
381 - perlio isn't generally threadsafe, so aio_close could not work reliably.
382 aio_close now tries a safe hack that might not be that asynchronous
383 (see the manpage for details).
384 - discard callback return values as to not grow the stack endlessly
385 when poll_cb handles many requests without returning.
386 - minor code cleanups.
387
3882.5 Thu Oct 4 14:49:08 CEST 2007
389 - replaced _fd2fh with faster xs code.
390 - aio_close will now try to do "the right thing" and thus might
391 work sensibly for the very first time.
392
3932.41 Mon Sep 24 21:28:21 CEST 2007
394 - after fork, invest some work to make sure that the poll_fileno
395 stays stable (by dup2'ing the new fd over the old one), to make
396 it easier for programs/libs that don't control their forking
397 behaviour and cannot recreate their watchers.
398
3992.4 Sun Aug 5 18:44:22 CEST 2007
400 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
401 successfully demonstrated that you can block on futimes...).
402 - allow undef as fileoffset for aio_read/write and use read/write(2)
403 internally (useful for sockets or O_APPEND handles).
404 - allow undef for length in aio_write.
405 - negative dataoffsets work as expected now in aio_read/aio_write.
406 - use NV instead of UV for 32 bit perls and file offsets, as NVs
407 have a larger range then.
408 - shared code between BDB and IO::AIO.
409 - aio_busy was completely broken. now fixed.
410 - readahead emulation now returns something.
411 - correctly set errno to ENOSYS on unimplemented functions
412 (should never happen, though).
413 - large changes to make it partially compile and run on win32,
414 but win32 lacks too much functionality, and perl overrides way
415 too many functions with crashing versions.
416
4172.33 Tue Jan 23 23:55:41 CET 2007
418 - fix install path (Andreas J. Koenig).
419
4202.32 Mon Jan 22 16:56:23 CET 2007
421 - added aio_rmtree.
422 - wow, aio_mkdir was missing.
423 - aio_load did return undef on error, not -1.
424 - use prefixexp not prefix in autoconf.pm
425 (suggested by ... rt.cpan.org unreachable).
426 - avoid installing autoconf.pm.
