41
42 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
43 were detected by autoconf.
44
454.6 Sat Aug 25 21:58:36 CEST 2018
46 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
47 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
48 but only st_gen on openbsd because they compiled their perl without support
49 for birthtimes).
50 - fix madvise and munlock to properly support negative offsets.
51 - allocate fd for the aio_close at boot time, to guarantee it working
52 later, rather than calling abort when it fails. also avoids
53 close-on-exec race issues after module load.
54 - #undef utime on win32, maybe this helps some reports of utime hangs.
55 - minor doc improvements.
56 - minor configure cleanups.
57 - use $Config{perllibs} instead of libs for configure. might help people
58 who didn'T install all perl dependencies (might break things as well).
59
604.54 Tue Aug 14 13:54:48 CEST 2018
61 - include sys/mkdev.h or sys/sysmacros.h if available.
62 - further tweaks to configure invocation for systems requiring --rpath.
63 - no longer rely on custom paths on win32 platforms.
64 - try to work around buggy PAGESIZE macro on solaris.
65
664.53 Tue Aug 14 11:27:50 CEST 2018
67 - add $Config{libs} to LIBS for configure, to work around systems
68 with broken library dependencies (... openbsd).
69
704.52 Sun Aug 12 08:09:45 CEST 2018
71 - config.h.in was missing in distribution.
72
734.51 Sun Aug 12 07:24:14 CEST 2018
74 - complete rework of the autoconf framework: IO::AIO now uses its own
75 config.h, separate from libeio, and tries to test the actual perl
76 environment, not the standard system environment.
77 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
78 stat functions.
79 - removed non-portable C++ syntax from eio.c.
80 - try to fix readdir tests on cygwin spuriously failing.
81
824.5 Wed Aug 1 00:23:55 CEST 2018
83 - aio_mtouch touch all pages as requested, not just the first page in most cases.
84 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
85 and MREMAP_FIXED.
86 - add O_ACCMODE.
87 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
88
894.4 Tue Feb 20 07:54:12 CET 2018

91 - add (experimental) IO::AIO::eventfd and timerfd* function.
92 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
93 - point out that aio_copy overwrites existing files.
94 - removed filesystem magic number table from aio_statvfs docs as
95 statvfs doesn't actually return this info at all (statfs does).
96 - add a bunch of (mostly linux-specific) constants for use in ioctls
97 (see aio_ioctl docs).
98 - treescan now has a proper manpage and useful --help output.
99 - new option --sync in treescan, to sync everything in a subtree.
100 - changed default for aio_msync flags to MSYNC_SYNC.
101 - document offset/length behaviour of mprotect/madvise.
102 - support linux's renameat2 (via aio_rename2).
103 - add aio_rename2, an aio_rename with flags.

110 and better eventfd detection.
111
1124.34 Sun May 1 19:18:24 CEST 2016
113 - def0.h was not properly generated during previous release, causing
114 compile errors on various platforms.
115 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
116 - removed duplicate definition of MAP_HUGETLB, that was found due to
117 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
118 - added (untested!) aio_fcntl, aio_ioctl requests.
119 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
120 as manpages-dev originally claimed.
121
1224.33 Mon Jan 18 12:50:10 CET 2016
123 - add IO::AIO::pipe2 function.
124 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
125 constants.
126 - added support for O_TMPFILE and O_PATH constants.
127 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
128 consdtants, whether they can be sensibly used or not.

133
1344.32 Wed Feb 11 20:32:11 CET 2015
135 - replace off_t by STRLEN where appropriate, should not result in
136 user-visible changes.
137 - update ecb.h for C11 compatibility.
138
1394.31 Tue Jun 3 03:29:27 CEST 2014
140 - work around more 5.20 bugs. backwards compatibility my ass.
141
1424.3 Fri Apr 11 06:22:38 CEST 2014
143 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
144 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
145 in 5.18. What's so attractive about giving a shit about backwards
146 compatibility - I will never understand.
147
1484.2 Sat Jan 25 01:13:14 CET 2014
149 - aio_group could corrupt memory because it didn't restore
150 the stack after req_submit.
151 - be more careful on (e.g. permission) errors in bin/treescan.
152 - work around changes in ExtUtils::MakeMaker.
153 - (libeio) implement aio_realpath for win32.
154 - (xthread) work around compile time bugs in ptw32.

156 - (libecb) insignificant update.
157
1584.19 Sun Jan 6 12:47:26 CET 2013
159 - avoid endless loop in fiemap with some XFS files.
160 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
161 and call rename/rmdir instead of renameat/unlinkat.
162
1634.18 Thu Oct 11 07:01:26 CEST 2012
164 - fix unintended xthread_create by intentionalising it :)
165
1664.17 Thu Oct 11 05:19:47 CEST 2012
167 - rename aio_fallocate to aio_allocate, to match documentation.
168 - add list of linux fsid values to aio_statvfs docs.
169 - work around a bug in btrfs' FIEMAP ioctl implementation.
170 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
171 as per unix spec.
172
1734.16 Tue Aug 14 05:39:03 CEST 2012
174 - aio_statvfs was wromgly marked for wd emulation, causing
175 it to malfunction for paths.
176 - fix a crash in aio_fiemap, when used on ranges without any
177 extents.
178 - work around linux kernel bug (at least in 3.2): kernel might
179 trash fiemap input arguments.
180 - work around linux kernel bug (at least in 3.2): kernel does not
181 set FIEMAP_EXTENT_LAST on last segment.
182 - work around linux kernel bug (at least in 3.2): kernel silently
183 truncates segment count if a file.
184 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
185 to quick overview.
186 - splice can corrupt data.
187 - (libeio) remove pread/pwrite emulation.
188 - do not grow mmaped scalars in aio_read.

191
1924.15 Tue Apr 10 06:59:00 CEST 2012
193 - always include linux/types.h for fiemap, for compatibility to
194 ancient systems (Paul Howarth).
195 - experimental support for IO::AIO::splice and ::tee (no aio_...).
196 - provide SEEK_HOLE and SEEK_DATA, if available.
197 - work around (again!) an immensely stupid bug in RHEL, defining
198 autoconf macros in linux system headers (analysed by Paul Howarth).
199
2004.14 Sat Apr 7 02:45:18 CEST 2012
201 - fix stat structure usage on windows, which caused bogus stat results.
202 - (libeio) make readahead emulation behave more like actual readahead by never failing.
203 - new request aio_seek.
204 - new request aio_fiemap.
205 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
206
2074.12 Fri Dec 30 08:51:25 CET 2011
208 - realpath would return a random value if the name was too long,
209 instead of -1.
210 - port to c89.
211
2124.11 Mon Oct 10 00:24:11 CEST 2011
213 - libeio didn't compile on !linux (Paul Howarth).
214
2154.1 Sun Oct 9 10:24:11 CEST 2011
216 - IO::AIO did access uninitialised memory on unsuccessful stats.
217 - (libeio) added syncfs syscall wrapper.
218 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
219 - (libeio) support multiple indepenent working directories.
220 - applied speling corrections by Nicholas Bamber.
221 - tune treescan #threads and #outstanding requests a bit.
222 - reduce the number of file descriptors in use at any one time
223 in treescan, to avoid running out of them (and using too much ram).
224 - take advantage of working directoriy abstractions
225 in aio_scandir and treescan.
226 - reduce compiled size by ~10% by not inlining some key functionality.
227 - added --progress switch to treescan.
228
2294.0 Mon Jul 18 05:01:10 CEST 2011
230 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
231 see FORK BEHAVIOUR in manpage for details.
232 - passes testsuite on win32 now and may actually work
233 (activestate 5.10.1 / MSVC6, YMMV).
234 - (libeio) fix a deadlock where a wakeup signal could be missed when
235 a timeout occured at the same time.
236 - (libeio) added realpath.
237 - (libeio) added fallocate.
238 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
239 - (libeio) do not acquire any locks when forking.
240 - (libeio) use fewer time() syscalls when waiting for new requests.
241
2423.93 Wed Jun 29 23:44:18 CEST 2011
243 - ECB.H WAS MISSING.
244
2453.92 Wed Jun 29 14:45:41 CEST 2011
246 - ecb.h was missing.
247
2483.91 Wed Jun 29 13:24:42 CEST 2011
249 - (libeio) work around a Linux (and likely FreeBSD and other
250 kernels) bug where sendfile would not transfer all the requested
251 bytes on large transfers, using a heuristic.
252 - buggy sendfile caused aio_move/copy to sometimes fail for big
253 files (fortunately it checks that the whole file has been
254 transferred...)
255 - use libecb for higher performance and higher portability.
256 - (libeio) disable sendfile on darwin, it's too broken.
257 - disable fork tests on !linux, as only linux supports mixing
258 pthread and fork in perl.
259 - document the fact that fork doesn't work anymore when using
260 this module, on anything !GNU/Linux.
261 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
262 run on a 0.1MHz cpu. Or so.
263
2643.9 Fri May 27 02:43:47 CEST 2011
265 - (libeio) fix memory corruption in aio_readdirx for the flags
266 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
267 - add lots of newer POSIX and GNU/Linux-specific open
268 flags.
269
2703.8 Sun Mar 27 12:25:33 CEST 2011
271 - use nonstandard but maybe-working-on-bsd fork technique.
272 - support a max_idle value of 0.
273 - support setting of idle timeout value (IO::AIO::idle_timeout).
274
2753.72 Fri Feb 11 04:25:38 CET 2011
276 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
277 - aio_mknod always used a dev_t value of 0.
278 - new treescan option: --grep.
279 - add more S_IF macros, and major/minor/makedev "macros".
280
2813.71 Thu Dec 30 08:18:46 CET 2010
282 - the numerical result value passed to callbacks did not stringify
283 correctly, due to internal reuse and failure to reset the sv flags.
284 - actually test for posix_[mf]advise, as at least uClibc defines
285 _POSIX_ADVISORY_INFO without actually having any of the required
286 funcitonality. ugh.
287
2883.7 Mon Nov 1 23:00:34 CET 2010
289 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
290 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
291 - document the sad state of affairs w.r.t. pthread on many bsds.
292 - do not enable mmap on systems without _POSIX_MAPPED_FILES
293 (openbsd 4.8).
294 - do not leak memory in IO::AIO::mmap when the scalar already
295 had string-data.
296 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
297 them.
298 - cache the result IV, for a minor speedup in the common case.
299 - croak when an mmapped-scalar changes location, to detect
300 user-errors better.
301 - fix aio_readlink prototype.
302
3033.65 Wed Mar 31 02:45:05 CEST 2010
304 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
305 cut off long pathnames in aio_readlink (based on patch by
306 Rasmus Andersson).
307 - a double fork partially killed the event pipe (great testcase
308 by dormando). affects IO::AIO, BDB and Async::Interrupt.
309 - suck steve's dick and rename our symbols to avoid colliding
310 with nonstandard identifier spam on the broken os x pseudo-os.
311 affects IO::AIO and BDB.
312
3133.6 Mon Jan 11 00:43:39 CET 2010
314 - (libeio) more fixes for the freebsd/apple sendfile - broken by
315 manpage standards, but apparently correct accoridng to actual
316 kernel sources.
317 - add IO::AIO::mmap/munmap support.
318 - add IO::AIO::m(un)lockall support.
319 - clean up manpage.
320
3213.5 Thu Jan 7 21:25:04 CET 2010
322 - (liebio) fix freebsd sendfile (Vanilla Hsu).
323 - (libeio) also fix darwin sendfile that suffered from a similar bug.
324 - add aio_statvfs as interface to statvfs/fstatvfs.
325 - work around buggy symlink() on cygwin in the testsuite.
326 - wtf. freebsd-8.0 actually passes the testsuite! I knew
327 they could implement fork and semaphores one day! cheers!
328
3293.4 Sat Jan 2 15:13:04 CET 2010
330 - (libeio) max_poll_time was not properly converted to ticks.
331 - clarify cancel_subs description.
332 - IO::AIO::sendfile did not actually return the return value
333 from the sendfile call.
334 - implement aio_msync, aio_mtouch.
335 - (libeio) tentatively support darwin in sendfile.
336
3373.31 Thu Nov 12 02:14:29 CET 2009
338 - fix result status documentation of aio_copy, aio_move.
339 - speed up object creation considerably by avoiding
340 hash lookups.
341
3423.3 Wed Aug 5 13:52:58 CEST 2009
343 - use common::sense.
344 - use common schmorp.h header.
345 - allow integers (file descriptors) in addition to file handles.
346 - take advantage of linux' eventfd (but it seems slower on smp?).
347 - use poll not select on posix platforms.
348
3493.261 Wed Jul 1 10:11:51 CEST 2009
350 - more 0S X workarounds (patch by Tokuhiro Matsuno).
351
3523.26 Tue Jun 30 09:33:26 CEST 2009
353 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
354 try to work around this horribly broken OS in a somewhat hackish
355 way. might help other os's too.
356
3573.25 Sat Jun 27 05:18:26 CEST 2009
358 - added IO::AIO::fadvise and IO::AIO::sendfile.
359 - (libeio) replaced quicksort+insertion sort by a tuned radix
360 sort + insertion sort, resulting in comparable runtime (usually
361 faster) to the old version, but without any ill side effects on
362 degenerated (for quicksort) data.
363 - (libeio) correctly sort dirs by inodes if we have perfect type
364 knowledge and DIRS_FIRST is used.
365 - (libeio) internally the wrong DT_* constants were used, but no
366 known system has differing EIO_DT_*/DT_* values, so not an issue.
367 - removed a (harmless) assert that was left over on the code
368 but should not have been.
369 - use more correct types (change IO length from IV to VAL64,
370 which makes a difference on systems without 64 bit perls).
371
3723.23 Sat Jun 13 16:57:58 CEST 2009
373 - fix off-by-one bug in aio_readdir that was introduced in the
374 rushed 3.22 release.
375
3763.22 Sat Jun 13 15:32:40 CEST 2009
377 - speed up readdirx sort algorithm slightly.
378 - bin/treescan was missing from distro tarball.
379
3803.21 Fri Jun 12 18:45:53 CEST 2009
381 - new options --dirs and --files for treescan.
382 - install bin/treescan by default.
383 - (libeio) aio_readdir can now be cancelled while executing.
384 - fix a printf format string for 64 bit systems (could lead
385 to problems on big endian 64 bit systems).
386 - do not use qsort() but our own algorithm: glibc initialises
387 the whole locale and I/O subsystem inside qsort, causing
388 a stack overflow on 32 bit machines. The new sort uses much less
389 stack and is more than twice as fast in typical situations.
390
3913.2 Sun Jun 7 20:30:05 CEST 2009
392 - (libeio) pwrite emulation was even more flawed than intended and did
393 not restore the file offset.
394 - add aio_readdirx, which can return inode and filetype and sort
395 the names in various ways.
396 - unfortunately, utime, chmod, chown on an open file that has just
397 been written can easily block, which caused aio_copy to block the
398 process. no more!
399 - no longer rely on dst path in aio_copy when futime is available.
400
4013.19 Tue Apr 21 22:05:21 CEST 2009
402 - more perl 5.10 workarounds for aio_read and write.
403 - aio_write no longer modifies the sv (if possible).
404 - aio_read now works correctly with magic values.
405
4063.18 Sun Apr 19 21:17:32 CEST 2009
407 - better diagnostics when some aio_* functions get passed an illegal fh.
408 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
409
4103.17 Thu Nov 20 08:45:36 CET 2008
411 - (libeio) added aio_sync_file_range (untested).
412 - add aio_busy to @IO::AIO::AIO_REQ.
413
4143.16 Wed Oct 22 18:28:01 CEST 2008
415 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
416 part to improve portability to perl 5.8 (reported by szymon).
417
4183.15 Mon Oct 13 00:39:55 CEST 2008
419 - automatic removal of feeders was broken.
420 - (libeio) use a more robust method to detect whether a feeder
421 has added something to the group or not.
422
4233.1 Thu Oct 2 13:34:40 CEST 2008
424 - pre-deref the passed callback object, for increased speed
425 and decreased memory usage.
426 - call on_next_submit callback even for aio_group - impact unknown,
427 but seems more correct.
428 - $req->cb now returns the original callback.
429 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
430 requiring a thread switch.
431 - (libeio) status code of aio_futime and aio_utime was always passed 0.
432 - do some other ยต-optimisations.
433
4343.07 Sat Aug 2 16:06:13 CEST 2008
435 - do not include LIBS in autoconf tests.
436
4373.06 Tue Jul 15 12:41:32 CEST 2008
438 - move preadwritelock definition before it's first reference,
439 to make it compile again on broken platforms (they still exist)
440 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
441
4423.05 Thu Jun 19 23:23:52 CEST 2008
443 - work around perl overriding readdir etc. with thread-unsafe
444 (sic!) versions.
445
4463.04 Wed Jun 18 01:35:38 CEST 2008
447 - (libeio) fix eio_mknod, which confused it's arguments.
448 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
449 is stupid.
450 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
451 - (libeio) fix a bug that could potentially cause IO::AIO
452 not to get initialised properly.
453
4543.03 Thu May 29 05:33:30 CEST 2008
455 - (libeio) correctly call pthread_attr_destroy ().
456 - (libeio) work around broken bsd headers once more.
457 - reduce shared library size again by not including wrappers.
458 - max_outstanding could cause poll to enter a busy-waiting loop.
459 - document the new IO::AIO::poll_cb result value.
460
4613.02 Mon May 12 02:32:02 CEST 2008
462 - fix a memory leak on aio_readlink.
463 - bring back working fchmod.
464 - nop and busy now set result to 0.
465 - set errno to ENOMEM when allocation fails.
466
4673.01 Sun May 11 03:07:03 CEST 2008
468 - (libeio) make it compile on systems without readahead or readdir_r.
469 - (libeio) improve configure check for readahead availability.
470 - do not try to link against -lrt.
471 - use a separate configure script for IO::AIO (not the libeio one).
472
4733.0 Sun May 11 00:57:14 CEST 2008
474 - added bin/treescan to the distribution.
475 - switched to using libeio.
476 - LOTS OF INCOMPATIBLE CHANGES:
477 - remove signal functionality, it is not worth the effort.
478 - max_outstanding no longer returns the previous number of requests.
479 - poll_cb no longer returns number of requests.
480
4812.62 Sat Apr 26 13:59:33 CEST 2008
482 - port to solaris perls configured for old posix
483 (analysed by Jost Krieger).
484 - keep a reference to the perl filehandle object in aio_close,
485 so it doesn't get closed prematurely, leading to ugly races.
486
4872.61 Wed Apr 16 18:45:02 CEST 2008
488 - fix treescan output duplication and improve output ordering.
489 also display files given on the commandline.
490 - use a different algorithm for aio_close that is faster
491 and probably has even lower chances of blocking.
492 - do our own stack memory management for threads - linux
493 allocates outrageous amounts of VM (not so bad unless you
494 use mlockall...), which severely limits the number of threads
495 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
496 and 4096 * sizeof (long) (usually this is 16..64k).
497
4982.6 Sun Mar 30 08:28:11 CEST 2008
499 - added aio_sync.
500 - added aio_pathsync.
501 - fix prototypes of (void) functions.
502
5032.51 Sat Oct 6 16:04:54 CEST 2007
504 - perlio isn't generally threadsafe, so aio_close could not work reliably.
505 aio_close now tries a safe hack that might not be that asynchronous
506 (see the manpage for details).
507 - discard callback return values as to not grow the stack endlessly
508 when poll_cb handles many requests without returning.
509 - minor code cleanups.
510
5112.5 Thu Oct 4 14:49:08 CEST 2007
512 - replaced _fd2fh with faster xs code.
513 - aio_close will now try to do "the right thing" and thus might
514 work sensibly for the very first time.
515
5162.41 Mon Sep 24 21:28:21 CEST 2007
517 - after fork, invest some work to make sure that the poll_fileno
518 stays stable (by dup2'ing the new fd over the old one), to make
519 it easier for programs/libs that don't control their forking
520 behaviour and cannot recreate their watchers.
521
5222.4 Sun Aug 5 18:44:22 CEST 2007
523 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
12 that you can block on futimes...). 524 successfully demonstrated that you can block on futimes...).
13 - allow undef as fileoffset for aio_read/write and use read/write(2) 525 - allow undef as fileoffset for aio_read/write and use read/write(2)
14 internally (useful for sockets or O_APPEND handles). 526 internally (useful for sockets or O_APPEND handles).
527 - allow undef for length in aio_write.
528 - negative dataoffsets work as expected now in aio_read/aio_write.
15 - use NV instead of UV for 32 bit perls and file offsets, as NVs 529 - use NV instead of UV for 32 bit perls and file offsets, as NVs
16 have a larger range then. 530 have a larger range then.
17 - shared code between BDB and IO::AIO. 531 - shared code between BDB and IO::AIO.
532 - aio_busy was completely broken. now fixed.
533 - readahead emulation now returns something.
18 - correctly set errno to ENOSYS on unimplemented functions 534 - correctly set errno to ENOSYS on unimplemented functions
19 (should never happen, though). 535 (should never happen, though).
536 - large changes to make it partially compile and run on win32,
537 but win32 lacks too much functionality, and perl overrides way
538 too many functions with crashing versions.

212.33 Tue Jan 23 23:55:41 CET 2007 5402.33 Tue Jan 23 23:55:41 CET 2007
22 - fix install path (Andreas J. Koenig). 541 - fix install path (Andreas J. Koenig).
