49
50 - aio_copy now tries to preallocate the destination file.
51 - fexecve configure test used the wrong püointer type (patch by Paul Howarth).
52
534.80 Sat 01 Apr 2023 04:13:37 CEST
54 - remove long obsolete "paths must be absolute" text in aio_open/stat
55 descriptions.
56 - another workaround for the low-quality musl libc.
57 - test for umount seperately, as it is more portable.
58 - some low-quality posix attempts (openbsd, osx) declare the availability
59 of fexecve but then don't even bother to implemnent a stub.
60
614.79 Sun 25 Sep 2022 18:25:53 CEST
62 - the autoconf result of the mount check was not used, so it failed to
63 compile on most systems (reported by crackoff@tutanota.com).
64 - work around fedora not having a working C compiler setup by design
65 (reported by Paul Howarth).
66
674.78 Tue 06 Sep 2022 12:54:43 CEST
68 - add IO::AIO::mount and IO::AIO::umount.
69 - add a bunch of symbols from sys/mount.h.
70
714.77 Mon 05 Sep 2022 02:03:38 CEST
72 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
73 - add fexecve.
74 - add lots of missing functions to @EXPORT_OK.
75
764.76 Tue Jul 27 20:45:01 CEST 2021
77 - add autoconf test for siginfo_t, which is, of course, not
78 available on windows (reported by Peter Petky).
79 - disable syscalls on solaris, as perl seems to provide an
80 incompatible syscall prototype that clashes with sys/syscall.h.
81 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
82 MAP_UNINITIALIZED.
83
844.75 Wed Dec 30 08:44:55 CET 2020
85 - removed leftover debug output from treescan.
86 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
87 FSCONFIG_*, MOUNT_ATTR_* constants.
88
894.74 Tue Dec 29 16:19:28 CET 2020
90 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
91 - rework bin/treescan to avoid recursion. This fixes two bugs
92 where a deep directory traversal or a lot of command line
93 arguments could cause it to crash.
94 - added (but not documented) open_tree, AT_* and move_mount flags.
95 - support defining syscall numbers in gendef0.
96
974.73 Fri Dec 4 02:08:37 CET 2020
98 - def0.h was not uptodate, running into musl problems
99 (reported by B Fraser).
100 - IO::AIO::splice and IO::AIO::tee didn't properly return
101 64 bit values.
102 - added IO::AIO::accept4.
103 - add various F_SEAL related fcntl constants.
104 - removed experimental marker for fdlimit functions.
105 - fiemap now includes the last segment even if it overflows
106 the end offset, which is arguably the correct behaviour.
107
1084.72 Wed Apr 3 04:56:03 CEST 2019
109 - (libeio) if fd 0 is available do not use it for aio_wd, as it
110 collides with IO::AIO::CWD.
111 - added IO::AIO::memfd_create.
112 - correctly include <sys/uio.h> in the vmsplice test.
113 - reduce codesize by ~7% on amd64 by declaring more functions
114 as noinline.
115 - documentation fixes and updates.
116 - experimental and undocumented preliminary support for synchronous statx.
117
1184.71 Sun Mar 10 13:09:26 CET 2019
119 - due to an error in the linux manpages, the configure tests
120 for readahead, sync_file_range, splice etc. failed. This has been fixed.
121
1224.7 Mon Mar 4 11:28:13 CET 2019
123 - majorly speed up scandir for the very special case of a non-POSIX
124 filesystem that nevertheless reports valid dt_type information.
125 The only known filesystem of this type is currently btrfs, which
126 didn't get it's act together to implement POSIX semantics in all
127 these years, and I am tired of waiting.
128 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
129 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
130 were detected by autoconf.
131
1324.6 Sat Aug 25 21:58:36 CEST 2018
133 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
134 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
135 but only st_gen on openbsd because they compiled their perl without support
136 for birthtimes).
137 - fix madvise and munlock to properly support negative offsets.
138 - allocate fd for the aio_close at boot time, to guarantee it working
139 later, rather than calling abort when it fails. also avoids
140 close-on-exec race issues after module load.
141 - #undef utime on win32, maybe this helps some reports of utime hangs.
142 - minor doc improvements.
143 - minor configure cleanups.
144 - use $Config{perllibs} instead of libs for configure. might help people
145 who didn't install all perl dependencies (might break things as well).
146
1474.54 Tue Aug 14 13:54:48 CEST 2018
148 - include sys/mkdev.h or sys/sysmacros.h if available.
149 - further tweaks to configure invocation for systems requiring --rpath.
150 - no longer rely on custom paths on win32 platforms.
151 - try to work around buggy PAGESIZE macro on solaris.
152
1534.53 Tue Aug 14 11:27:50 CEST 2018
154 - add $Config{libs} to LIBS for configure, to work around systems
155 with broken library dependencies (... openbsd).
156
1574.52 Sun Aug 12 08:09:45 CEST 2018
158 - config.h.in was missing in distribution.
159
1604.51 Sun Aug 12 07:24:14 CEST 2018
161 - complete rework of the autoconf framework: IO::AIO now uses its own
162 config.h, separate from libeio, and tries to test the actual perl
163 environment, not the standard system environment.
164 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
165 stat functions.
166 - removed non-portable C++ syntax from eio.c.
167 - try to fix readdir tests on cygwin spuriously failing.
168
1694.5 Wed Aug 1 00:23:55 CEST 2018
170 - aio_mtouch touch all pages as requested, not just the first page in most cases.
171 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
172 and MREMAP_FIXED.
173 - add O_ACCMODE.
174 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
175
1764.4 Tue Feb 20 07:54:12 CET 2018
177 - new aio_slurp request.
178 - add (experimental) IO::AIO::eventfd and timerfd* function.
179 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
180 - point out that aio_copy overwrites existing files.
181 - removed filesystem magic number table from aio_statvfs docs as
182 statvfs doesn't actually return this info at all (statfs does).
183 - add a bunch of (mostly linux-specific) constants for use in ioctls
184 (see aio_ioctl docs).
185 - treescan now has a proper manpage and useful --help output.
186 - new option --sync in treescan, to sync everything in a subtree.
187 - changed default for aio_msync flags to MSYNC_SYNC.
188 - document offset/length behaviour of mprotect/madvise.
189 - support linux's renameat2 (via aio_rename2).
190 - add aio_rename2, an aio_rename with flags.
191 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
192 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
193 - (libeio) use posix_close if available.
194 - (libeio) internal close() calls no longer disturb errno.
195 - add IO:AIO::FALLOC_FL_UNSHARE.
196 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
197 and better eventfd detection.
198
1994.34 Sun May 1 19:18:24 CEST 2016
200 - def0.h was not properly generated during previous release, causing
201 compile errors on various platforms.
202 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
203 - removed duplicate definition of MAP_HUGETLB, that was found due to
204 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
205 - added (untested!) aio_fcntl, aio_ioctl requests.
206 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
207 as manpages-dev originally claimed.
208
2094.33 Mon Jan 18 12:50:10 CET 2016
210 - add IO::AIO::pipe2 function.
211 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
212 constants.
213 - added support for O_TMPFILE and O_PATH constants.
214 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
215 consdtants, whether they can be sensibly used or not.
216 - use NO_INIT where applicable.
217 - update libecb.
218 - added stability canary support.
219 - updated linux super magic table to 4.3.3.
220
2214.32 Wed Feb 11 20:32:11 CET 2015
222 - replace off_t by STRLEN where appropriate, should not result in
223 user-visible changes.
224 - update ecb.h for C11 compatibility.
225
2264.31 Tue Jun 3 03:29:27 CEST 2014
227 - work around more 5.20 bugs. backwards compatibility my ass.
228
2294.3 Fri Apr 11 06:22:38 CEST 2014
230 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
231 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
232 in 5.18. What's so attractive about giving a shit about backwards
233 compatibility - I will never understand.
234
2354.2 Sat Jan 25 01:13:14 CET 2014
236 - aio_group could corrupt memory because it didn't restore
237 the stack after req_submit.
238 - be more careful on (e.g. permission) errors in bin/treescan.
239 - work around changes in ExtUtils::MakeMaker.
240 - (libeio) implement aio_realpath for win32.
241 - (xthread) work around compile time bugs in ptw32.
242 - added IO::AIO::pipesize.
243 - (libecb) insignificant update.
244
2454.19 Sun Jan 6 12:47:26 CET 2013
246 - avoid endless loop in fiemap with some XFS files.
247 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
248 and call rename/rmdir instead of renameat/unlinkat.
249
2504.18 Thu Oct 11 07:01:26 CEST 2012
251 - fix unintended xthread_create by intentionalising it :)
252
2534.17 Thu Oct 11 05:19:47 CEST 2012
254 - rename aio_fallocate to aio_allocate, to match documentation.
255 - add list of linux fsid values to aio_statvfs docs.
256 - work around a bug in btrfs' FIEMAP ioctl implementation.
257 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
258 as per unix spec.
259
2604.16 Tue Aug 14 05:39:03 CEST 2012
261 - aio_statvfs was wromgly marked for wd emulation, causing
262 it to malfunction for paths.
263 - fix a crash in aio_fiemap, when used on ranges without any
264 extents.
265 - work around linux kernel bug (at least in 3.2): kernel might
266 trash fiemap input arguments.
267 - work around linux kernel bug (at least in 3.2): kernel does not
268 set FIEMAP_EXTENT_LAST on last segment.
269 - work around linux kernel bug (at least in 3.2): kernel silently
270 truncates segment count if a file.
271 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
272 to quick overview.
273 - splice can corrupt data.
274 - (libeio) remove pread/pwrite emulation.
275 - do not grow mmaped scalars in aio_read.
276 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
277 - provide pread/pwrite for win32, making it link again on native win32.
278
2794.15 Tue Apr 10 06:59:00 CEST 2012
280 - always include linux/types.h for fiemap, for compatibility to
281 ancient systems (Paul Howarth).
282 - experimental support for IO::AIO::splice and ::tee (no aio_...).
283 - provide SEEK_HOLE and SEEK_DATA, if available.
284 - work around (again!) an immensely stupid bug in RHEL, defining
285 autoconf macros in linux system headers (analysed by Paul Howarth).
286
2874.14 Sat Apr 7 02:45:18 CEST 2012
288 - fix stat structure usage on windows, which caused bogus stat results.
289 - (libeio) make readahead emulation behave more like actual readahead by never failing.
290 - new request aio_seek.
291 - new request aio_fiemap.
292 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
293
2944.12 Fri Dec 30 08:51:25 CET 2011
295 - realpath would return a random value if the name was too long,
296 instead of -1.
297 - port to c89.
298
2994.11 Mon Oct 10 00:24:11 CEST 2011
300 - libeio didn't compile on !linux (Paul Howarth).
301
3024.1 Sun Oct 9 10:24:11 CEST 2011
303 - IO::AIO did access uninitialised memory on unsuccessful stats.
304 - (libeio) added syncfs syscall wrapper.
305 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
306 - (libeio) support multiple indepenent working directories.
307 - applied speling corrections by Nicholas Bamber.
308 - tune treescan #threads and #outstanding requests a bit.
309 - reduce the number of file descriptors in use at any one time
310 in treescan, to avoid running out of them (and using too much ram).
311 - take advantage of working directoriy abstractions
312 in aio_scandir and treescan.
313 - reduce compiled size by ~10% by not inlining some key functionality.
314 - added --progress switch to treescan.
315
3164.0 Mon Jul 18 05:01:10 CEST 2011
317 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
318 see FORK BEHAVIOUR in manpage for details.
319 - passes testsuite on win32 now and may actually work
320 (activestate 5.10.1 / MSVC6, YMMV).
321 - (libeio) fix a deadlock where a wakeup signal could be missed when
322 a timeout occured at the same time.
323 - (libeio) added realpath.
324 - (libeio) added fallocate.
325 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
326 - (libeio) do not acquire any locks when forking.
327 - (libeio) use fewer time() syscalls when waiting for new requests.
328
3293.93 Wed Jun 29 23:44:18 CEST 2011
330 - ECB.H WAS MISSING.
331
3323.92 Wed Jun 29 14:45:41 CEST 2011
333 - ecb.h was missing.
334
3353.91 Wed Jun 29 13:24:42 CEST 2011
336 - (libeio) work around a Linux (and likely FreeBSD and other
337 kernels) bug where sendfile would not transfer all the requested
338 bytes on large transfers, using a heuristic.
339 - buggy sendfile caused aio_move/copy to sometimes fail for big
340 files (fortunately it checks that the whole file has been
341 transferred...)
342 - use libecb for higher performance and higher portability.
343 - (libeio) disable sendfile on darwin, it's too broken.
344 - disable fork tests on !linux, as only linux supports mixing
345 pthread and fork in perl.
346 - document the fact that fork doesn't work anymore when using
347 this module, on anything !GNU/Linux.
348 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
349 run on a 0.1MHz cpu. Or so.
350
3513.9 Fri May 27 02:43:47 CEST 2011
352 - (libeio) fix memory corruption in aio_readdirx for the flags
353 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
354 - add lots of newer POSIX and GNU/Linux-specific open
355 flags.
356

358 - use nonstandard but maybe-working-on-bsd fork technique.
359 - support a max_idle value of 0.
360 - support setting of idle timeout value (IO::AIO::idle_timeout).
361
3623.72 Fri Feb 11 04:25:38 CET 2011
363 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
364 - aio_mknod always used a dev_t value of 0.
365 - new treescan option: --grep.
366 - add more S_IF macros, and major/minor/makedev "macros".
367
3683.71 Thu Dec 30 08:18:46 CET 2010
369 - the numerical result value passed to callbacks did not stringify
370 correctly, due to internal reuse and failure to reset the sv flags.
371 - actually test for posix_[mf]advise, as at least uClibc defines
372 _POSIX_ADVISORY_INFO without actually having any of the required
373 funcitonality. ugh.
374
3753.7 Mon Nov 1 23:00:34 CET 2010
376 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
377 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
378 - document the sad state of affairs w.r.t. pthread on many bsds.
379 - do not enable mmap on systems without _POSIX_MAPPED_FILES
380 (openbsd 4.8).
381 - do not leak memory in IO::AIO::mmap when the scalar already
382 had string-data.
383 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
384 them.
385 - cache the result IV, for a minor speedup in the common case.
386 - croak when an mmapped-scalar changes location, to detect
387 user-errors better.
388 - fix aio_readlink prototype.
389
3903.65 Wed Mar 31 02:45:05 CEST 2010
391 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
392 cut off long pathnames in aio_readlink (based on patch by
393 Rasmus Andersson).
394 - a double fork partially killed the event pipe (great testcase
395 by dormando). affects IO::AIO, BDB and Async::Interrupt.
396 - suck steve's dick and rename our symbols to avoid colliding
397 with nonstandard identifier spam on the broken os x pseudo-os.
398 affects IO::AIO and BDB.
399
4003.6 Mon Jan 11 00:43:39 CET 2010
401 - (libeio) more fixes for the freebsd/apple sendfile - broken by
402 manpage standards, but apparently correct accoridng to actual
403 kernel sources.
404 - add IO::AIO::mmap/munmap support.
405 - add IO::AIO::m(un)lockall support.
406 - clean up manpage.
407
4083.5 Thu Jan 7 21:25:04 CET 2010
409 - (liebio) fix freebsd sendfile (Vanilla Hsu).
410 - (libeio) also fix darwin sendfile that suffered from a similar bug.
411 - add aio_statvfs as interface to statvfs/fstatvfs.
412 - work around buggy symlink() on cygwin in the testsuite.
413 - wtf. freebsd-8.0 actually passes the testsuite! I knew
414 they could implement fork and semaphores one day! cheers!
415
4163.4 Sat Jan 2 15:13:04 CET 2010
417 - (libeio) max_poll_time was not properly converted to ticks.
418 - clarify cancel_subs description.
419 - IO::AIO::sendfile did not actually return the return value
420 from the sendfile call.
421 - implement aio_msync, aio_mtouch.
422 - (libeio) tentatively support darwin in sendfile.
423
4243.31 Thu Nov 12 02:14:29 CET 2009
425 - fix result status documentation of aio_copy, aio_move.
426 - speed up object creation considerably by avoiding
427 hash lookups.
428
4293.3 Wed Aug 5 13:52:58 CEST 2009
430 - use common::sense.
431 - use common schmorp.h header.
432 - allow integers (file descriptors) in addition to file handles.
433 - take advantage of linux' eventfd (but it seems slower on smp?).
434 - use poll not select on posix platforms.
435
4363.261 Wed Jul 1 10:11:51 CEST 2009
437 - more 0S X workarounds (patch by Tokuhiro Matsuno).
438
4393.26 Tue Jun 30 09:33:26 CEST 2009
440 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
441 try to work around this horribly broken OS in a somewhat hackish
442 way. might help other os's too.
443
4443.25 Sat Jun 27 05:18:26 CEST 2009
445 - added IO::AIO::fadvise and IO::AIO::sendfile.
446 - (libeio) replaced quicksort+insertion sort by a tuned radix
447 sort + insertion sort, resulting in comparable runtime (usually
448 faster) to the old version, but without any ill side effects on
449 degenerated (for quicksort) data.
450 - (libeio) correctly sort dirs by inodes if we have perfect type
451 knowledge and DIRS_FIRST is used.
452 - (libeio) internally the wrong DT_* constants were used, but no
453 known system has differing EIO_DT_*/DT_* values, so not an issue.
454 - removed a (harmless) assert that was left over on the code
455 but should not have been.
456 - use more correct types (change IO length from IV to VAL64,
457 which makes a difference on systems without 64 bit perls).
458
4593.23 Sat Jun 13 16:57:58 CEST 2009
460 - fix off-by-one bug in aio_readdir that was introduced in the
461 rushed 3.22 release.
462
4633.22 Sat Jun 13 15:32:40 CEST 2009
464 - speed up readdirx sort algorithm slightly.
465 - bin/treescan was missing from distro tarball.
466
4673.21 Fri Jun 12 18:45:53 CEST 2009
468 - new options --dirs and --files for treescan.
469 - install bin/treescan by default.
470 - (libeio) aio_readdir can now be cancelled while executing.
471 - fix a printf format string for 64 bit systems (could lead
472 to problems on big endian 64 bit systems).
473 - do not use qsort() but our own algorithm: glibc initialises
474 the whole locale and I/O subsystem inside qsort, causing
475 a stack overflow on 32 bit machines. The new sort uses much less
476 stack and is more than twice as fast in typical situations.
477
4783.2 Sun Jun 7 20:30:05 CEST 2009
479 - (libeio) pwrite emulation was even more flawed than intended and did
480 not restore the file offset.
481 - add aio_readdirx, which can return inode and filetype and sort
482 the names in various ways.
483 - unfortunately, utime, chmod, chown on an open file that has just
484 been written can easily block, which caused aio_copy to block the
485 process. no more!
486 - no longer rely on dst path in aio_copy when futime is available.
487
4883.19 Tue Apr 21 22:05:21 CEST 2009
489 - more perl 5.10 workarounds for aio_read and write.
490 - aio_write no longer modifies the sv (if possible).
491 - aio_read now works correctly with magic values.
492
4933.18 Sun Apr 19 21:17:32 CEST 2009
494 - better diagnostics when some aio_* functions get passed an illegal fh.
495 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
496
4973.17 Thu Nov 20 08:45:36 CET 2008
498 - (libeio) added aio_sync_file_range (untested).
499 - add aio_busy to @IO::AIO::AIO_REQ.
500
5013.16 Wed Oct 22 18:28:01 CEST 2008
502 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
503 part to improve portability to perl 5.8 (reported by szymon).
504
5053.15 Mon Oct 13 00:39:55 CEST 2008
506 - automatic removal of feeders was broken.
507 - (libeio) use a more robust method to detect whether a feeder
508 has added something to the group or not.
509
5103.1 Thu Oct 2 13:34:40 CEST 2008
511 - pre-deref the passed callback object, for increased speed
512 and decreased memory usage.
513 - call on_next_submit callback even for aio_group - impact unknown,
514 but seems more correct.
515 - $req->cb now returns the original callback.
516 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
517 requiring a thread switch.
518 - (libeio) status code of aio_futime and aio_utime was always passed 0.
519 - do some other µ-optimisations.
520
5213.07 Sat Aug 2 16:06:13 CEST 2008
522 - do not include LIBS in autoconf tests.
523
5243.06 Tue Jul 15 12:41:32 CEST 2008
525 - move preadwritelock definition before it's first reference,
526 to make it compile again on broken platforms (they still exist)
527 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
528
5293.05 Thu Jun 19 23:23:52 CEST 2008
530 - work around perl overriding readdir etc. with thread-unsafe
531 (sic!) versions.
532
5333.04 Wed Jun 18 01:35:38 CEST 2008
534 - (libeio) fix eio_mknod, which confused it's arguments.
535 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
536 is stupid.
537 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
538 - (libeio) fix a bug that could potentially cause IO::AIO
539 not to get initialised properly.
540
5413.03 Thu May 29 05:33:30 CEST 2008
542 - (libeio) correctly call pthread_attr_destroy ().
543 - (libeio) work around broken bsd headers once more.
544 - reduce shared library size again by not including wrappers.
545 - max_outstanding could cause poll to enter a busy-waiting loop.
546 - document the new IO::AIO::poll_cb result value.
547
5483.02 Mon May 12 02:32:02 CEST 2008
549 - fix a memory leak on aio_readlink.
550 - bring back working fchmod.
551 - nop and busy now set result to 0.
552 - set errno to ENOMEM when allocation fails.
553
5543.01 Sun May 11 03:07:03 CEST 2008
555 - (libeio) make it compile on systems without readahead or readdir_r.
556 - (libeio) improve configure check for readahead availability.
557 - do not try to link against -lrt.
558 - use a separate configure script for IO::AIO (not the libeio one).
559
5603.0 Sun May 11 00:57:14 CEST 2008
561 - added bin/treescan to the distribution.
562 - switched to using libeio.
563 - LOTS OF INCOMPATIBLE CHANGES:
564 - remove signal functionality, it is not worth the effort.
565 - max_outstanding no longer returns the previous number of requests.
566 - poll_cb no longer returns number of requests.
567
5682.62 Sat Apr 26 13:59:33 CEST 2008
569 - port to solaris perls configured for old posix
570 (analysed by Jost Krieger).
571 - keep a reference to the perl filehandle object in aio_close,
572 so it doesn't get closed prematurely, leading to ugly races.
573
5742.61 Wed Apr 16 18:45:02 CEST 2008
575 - fix treescan output duplication and improve output ordering.
576 also display files given on the commandline.
577 - use a different algorithm for aio_close that is faster
578 and probably has even lower chances of blocking.
579 - do our own stack memory management for threads - linux
580 allocates outrageous amounts of VM (not so bad unless you
581 use mlockall...), which severely limits the number of threads
582 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
583 and 4096 * sizeof (long) (usually this is 16..64k).
584
5852.6 Sun Mar 30 08:28:11 CEST 2008
586 - added aio_sync.
587 - added aio_pathsync.
588 - fix prototypes of (void) functions.
589
5902.51 Sat Oct 6 16:04:54 CEST 2007
591 - perlio isn't generally threadsafe, so aio_close could not work reliably.
592 aio_close now tries a safe hack that might not be that asynchronous
593 (see the manpage for details).
594 - discard callback return values as to not grow the stack endlessly
595 when poll_cb handles many requests without returning.
596 - minor code cleanups.
597
5982.5 Thu Oct 4 14:49:08 CEST 2007
599 - replaced _fd2fh with faster xs code.
600 - aio_close will now try to do "the right thing" and thus might
601 work sensibly for the very first time.
602
6032.41 Mon Sep 24 21:28:21 CEST 2007
604 - after fork, invest some work to make sure that the poll_fileno
605 stays stable (by dup2'ing the new fd over the old one), to make
606 it easier for programs/libs that don't control their forking
607 behaviour and cannot recreate their watchers.
608
6092.4 Sun Aug 5 18:44:22 CEST 2007
610 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
611 successfully demonstrated that you can block on futimes...).
612 - allow undef as fileoffset for aio_read/write and use read/write(2)
613 internally (useful for sockets or O_APPEND handles).
614 - allow undef for length in aio_write.
615 - negative dataoffsets work as expected now in aio_read/aio_write.
616 - use NV instead of UV for 32 bit perls and file offsets, as NVs
617 have a larger range then.
618 - shared code between BDB and IO::AIO.
619 - aio_busy was completely broken. now fixed.
620 - readahead emulation now returns something.
621 - correctly set errno to ENOSYS on unimplemented functions
622 (should never happen, though).
623 - large changes to make it partially compile and run on win32,
624 but win32 lacks too much functionality, and perl overrides way
625 too many functions with crashing versions.
626
6272.33 Tue Jan 23 23:55:41 CET 2007
628 - fix install path (Andreas J. Koenig).
629
6302.32 Mon Jan 22 16:56:23 CET 2007
631 - added aio_rmtree.
632 - wow, aio_mkdir was missing.
633 - aio_load did return undef on error, not -1.
634 - use prefixexp not prefix in autoconf.pm
635 (suggested by ... rt.cpan.org unreachable).
636 - avoid installing autoconf.pm.
637
6382.31 Sat Jan 6 03:46:02 CET 2007
639 - added aio_load.
640
6412.3 Sat Dec 23 05:48:07 CET 2006
642 - fix off-by-one bug in aio_read, causing memory corruption
643 or crashes.
644
6452.21 Fri Dec 22 05:03:38 CET 2006
646 - minor doc updates.
647 - minor cleanups.
648 - IO::AIO::poll returns request count.
649 - undocumented and unfinished async-signal-reporting.
650
6512.2 Tue Oct 31 00:31:00 CET 2006
652 - minor doc updates.
653 - added aio_readlink.
654 - properly zero-terminate aio_read buffer.
655 - fix aio_read/write with nonzero dataoffset.
656 - reduced size of aio request structure.
657 - better diagnostics when pathnames etc. are not byte-encoded;
658 do not leak request in that case, either.
659
6602.1 Sun Oct 29 02:01:57 CET 2006
661 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
662 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
663 - fix a bug in aio_move where it would fail everytime
664 it would have to copy files manually.
665 - doc updates.
666 - start threads only on (very low) demand.
667 - end superfluous threads automatically after 10s idling.
668 - add IO::AIO::max_idle to control this.
669 - some tuning applied to random places.
670 - add aio_mknod.
671
6722.0 Thu Oct 26 18:27:58 CEST 2006
673 - minor incompatibility: max_outstanding semantics have changed.
674 - major rewrite, consider all functionality EXPERIMENTAL.
7 - aio requests can be cancelled. 675 - aio requests can be cancelled.
676 - callbacks can be (re-)set later.
677 - aio requests can choose between 9 priorities.
8 - add aio_group: aio requests can be grouped. 678 - add aio_group: aio requests can be grouped
679 into composite requests.
9 - implement generator interface for groups. 680 - generator interface for groups.

684 - add aio_nop for dummy requests.
685 - add aio_busy mainly for benchmarking and debugging.
686 - use "fast" mutexes on linux.
687 - use dynamic (and larger) buffers instead of
688 putting them onto the stack.
689 - optimise x86 and amd64 a bit.
690 - better error checking when ENOMEM.
691 - hopefully fix mem and dirp leaks on fork.
692 - warn about broken perl malloc.
693 - compiles on cygwin (but pread is broken on cygwin
694 which is not detected by autoconf, so you have to
695 edit autoconf/config.h yourself to enable emulation).
13 696
141.8 Sat Jun 24 22:20:44 CEST 2006 6971.8 Sat Jun 24 22:20:44 CEST 2006
