51
524.74 Tue Dec 29 16:19:28 CET 2020
53 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
54 - rework bin/treescan to avoid recursion. This fixes two bugs
55 where a deep directory traversal or a lot of command line
56 arguments could cause it to crash.
57 - added (but not documented) open_tree, AT_* and move_mount flags.
58 - support defining syscall numbers in gendef0.
59
604.73 Fri Dec 4 02:08:37 CET 2020
61 - def0.h was not uptodate, running into musl problems
62 (reported by B Fraser).
63 - IO::AIO::splice and IO::AIO::tee didn't properly return
64 64 bit values.
65 - added IO::AIO::accept4.
66 - add various F_SEAL related fcntl constants.
67 - removed experimental marker for fdlimit functions.
68 - fiemap now includes the last segment even if it overflows
69 the end offset, which is arguably the correct behaviour.
70
714.72 Wed Apr 3 04:56:03 CEST 2019
72 - (libeio) if fd 0 is available do not use it for aio_wd, as it
73 collides with IO::AIO::CWD.
74 - added IO::AIO::memfd_create.
75 - correctly include <sys/uio.h> in the vmsplice test.
76 - reduce codesize by ~7% on amd64 by declaring more functions
77 as noinline.
78 - documentation fixes and updates.
79 - experimental and undocumented preliminary support for synchronous statx.
80
814.71 Sun Mar 10 13:09:26 CET 2019
82 - due to an error in the linux manpages, the configure tests
83 for readahead, sync_file_range, splice etc. failed. This has been fixed.
84
854.7 Mon Mar 4 11:28:13 CET 2019
86 - majorly speed up scandir for the very special case of a non-POSIX
87 filesystem that nevertheless reports valid dt_type information.
88 The only known filesystem of this type is currently btrfs, which
89 didn't get it's act together to implement POSIX semantics in all
90 these years, and I am tired of waiting.
91 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
92 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
93 were detected by autoconf.
94
954.6 Sat Aug 25 21:58:36 CEST 2018
96 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
97 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
98 but only st_gen on openbsd because they compiled their perl without support
99 for birthtimes).
100 - fix madvise and munlock to properly support negative offsets.
101 - allocate fd for the aio_close at boot time, to guarantee it working
102 later, rather than calling abort when it fails. also avoids
103 close-on-exec race issues after module load.
104 - #undef utime on win32, maybe this helps some reports of utime hangs.
105 - minor doc improvements.
106 - minor configure cleanups.
107 - use $Config{perllibs} instead of libs for configure. might help people
108 who didn't install all perl dependencies (might break things as well).
109
1104.54 Tue Aug 14 13:54:48 CEST 2018
111 - include sys/mkdev.h or sys/sysmacros.h if available.
112 - further tweaks to configure invocation for systems requiring --rpath.
113 - no longer rely on custom paths on win32 platforms.
114 - try to work around buggy PAGESIZE macro on solaris.
115
1164.53 Tue Aug 14 11:27:50 CEST 2018
117 - add $Config{libs} to LIBS for configure, to work around systems
118 with broken library dependencies (... openbsd).
119
1204.52 Sun Aug 12 08:09:45 CEST 2018
121 - config.h.in was missing in distribution.
122
1234.51 Sun Aug 12 07:24:14 CEST 2018
124 - complete rework of the autoconf framework: IO::AIO now uses its own
125 config.h, separate from libeio, and tries to test the actual perl
126 environment, not the standard system environment.
127 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
128 stat functions.
129 - removed non-portable C++ syntax from eio.c.
130 - try to fix readdir tests on cygwin spuriously failing.
131
1324.5 Wed Aug 1 00:23:55 CEST 2018
133 - aio_mtouch touch all pages as requested, not just the first page in most cases.
134 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
135 and MREMAP_FIXED.
136 - add O_ACCMODE.
137 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
138
1394.4 Tue Feb 20 07:54:12 CET 2018
140 - new aio_slurp request.
141 - add (experimental) IO::AIO::eventfd and timerfd* function.
142 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
143 - point out that aio_copy overwrites existing files.
144 - removed filesystem magic number table from aio_statvfs docs as
145 statvfs doesn't actually return this info at all (statfs does).
146 - add a bunch of (mostly linux-specific) constants for use in ioctls
147 (see aio_ioctl docs).
148 - treescan now has a proper manpage and useful --help output.
149 - new option --sync in treescan, to sync everything in a subtree.
150 - changed default for aio_msync flags to MSYNC_SYNC.
151 - document offset/length behaviour of mprotect/madvise.
152 - support linux's renameat2 (via aio_rename2).
153 - add aio_rename2, an aio_rename with flags.
154 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
155 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
156 - (libeio) use posix_close if available.
157 - (libeio) internal close() calls no longer disturb errno.
158 - add IO:AIO::FALLOC_FL_UNSHARE.
159 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
160 and better eventfd detection.
161
1624.34 Sun May 1 19:18:24 CEST 2016
163 - def0.h was not properly generated during previous release, causing
164 compile errors on various platforms.
165 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
166 - removed duplicate definition of MAP_HUGETLB, that was found due to
167 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
168 - added (untested!) aio_fcntl, aio_ioctl requests.
169 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
170 as manpages-dev originally claimed.
171
1724.33 Mon Jan 18 12:50:10 CET 2016
173 - add IO::AIO::pipe2 function.
174 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
175 constants.
176 - added support for O_TMPFILE and O_PATH constants.
177 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
178 consdtants, whether they can be sensibly used or not.
179 - use NO_INIT where applicable.
180 - update libecb.
181 - added stability canary support.
182 - updated linux super magic table to 4.3.3.
183
1844.32 Wed Feb 11 20:32:11 CET 2015
185 - replace off_t by STRLEN where appropriate, should not result in
186 user-visible changes.
187 - update ecb.h for C11 compatibility.
188
1894.31 Tue Jun 3 03:29:27 CEST 2014
190 - work around more 5.20 bugs. backwards compatibility my ass.
191
1924.3 Fri Apr 11 06:22:38 CEST 2014
193 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
194 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
195 in 5.18. What's so attractive about giving a shit about backwards
196 compatibility - I will never understand.
197
1984.2 Sat Jan 25 01:13:14 CET 2014
199 - aio_group could corrupt memory because it didn't restore
200 the stack after req_submit.
201 - be more careful on (e.g. permission) errors in bin/treescan.
202 - work around changes in ExtUtils::MakeMaker.
203 - (libeio) implement aio_realpath for win32.
204 - (xthread) work around compile time bugs in ptw32.
205 - added IO::AIO::pipesize.
206 - (libecb) insignificant update.
207
2084.19 Sun Jan 6 12:47:26 CET 2013
209 - avoid endless loop in fiemap with some XFS files.
210 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
211 and call rename/rmdir instead of renameat/unlinkat.
212
2134.18 Thu Oct 11 07:01:26 CEST 2012
214 - fix unintended xthread_create by intentionalising it :)
215
2164.17 Thu Oct 11 05:19:47 CEST 2012
217 - rename aio_fallocate to aio_allocate, to match documentation.
218 - add list of linux fsid values to aio_statvfs docs.
219 - work around a bug in btrfs' FIEMAP ioctl implementation.
220 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
221 as per unix spec.
222
2234.16 Tue Aug 14 05:39:03 CEST 2012
224 - aio_statvfs was wromgly marked for wd emulation, causing
225 it to malfunction for paths.
226 - fix a crash in aio_fiemap, when used on ranges without any
227 extents.
228 - work around linux kernel bug (at least in 3.2): kernel might
229 trash fiemap input arguments.
230 - work around linux kernel bug (at least in 3.2): kernel does not
231 set FIEMAP_EXTENT_LAST on last segment.
232 - work around linux kernel bug (at least in 3.2): kernel silently
233 truncates segment count if a file.
234 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
235 to quick overview.
236 - splice can corrupt data.
237 - (libeio) remove pread/pwrite emulation.
238 - do not grow mmaped scalars in aio_read.

241
2424.15 Tue Apr 10 06:59:00 CEST 2012
243 - always include linux/types.h for fiemap, for compatibility to
244 ancient systems (Paul Howarth).
245 - experimental support for IO::AIO::splice and ::tee (no aio_...).
246 - provide SEEK_HOLE and SEEK_DATA, if available.
247 - work around (again!) an immensely stupid bug in RHEL, defining
248 autoconf macros in linux system headers (analysed by Paul Howarth).
249
2504.14 Sat Apr 7 02:45:18 CEST 2012
251 - fix stat structure usage on windows, which caused bogus stat results.
252 - (libeio) make readahead emulation behave more like actual readahead by never failing.
253 - new request aio_seek.
254 - new request aio_fiemap.
255 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
256
2574.12 Fri Dec 30 08:51:25 CET 2011
258 - realpath would return a random value if the name was too long,
259 instead of -1.
260 - port to c89.
261
2624.11 Mon Oct 10 00:24:11 CEST 2011
263 - libeio didn't compile on !linux (Paul Howarth).
264
2654.1 Sun Oct 9 10:24:11 CEST 2011
266 - IO::AIO did access uninitialised memory on unsuccessful stats.
267 - (libeio) added syncfs syscall wrapper.
268 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
269 - (libeio) support multiple indepenent working directories.
270 - applied speling corrections by Nicholas Bamber.
271 - tune treescan #threads and #outstanding requests a bit.
272 - reduce the number of file descriptors in use at any one time
273 in treescan, to avoid running out of them (and using too much ram).
274 - take advantage of working directoriy abstractions
275 in aio_scandir and treescan.
276 - reduce compiled size by ~10% by not inlining some key functionality.
277 - added --progress switch to treescan.
278
2794.0 Mon Jul 18 05:01:10 CEST 2011
280 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
281 see FORK BEHAVIOUR in manpage for details.
282 - passes testsuite on win32 now and may actually work
283 (activestate 5.10.1 / MSVC6, YMMV).
284 - (libeio) fix a deadlock where a wakeup signal could be missed when
285 a timeout occured at the same time.
286 - (libeio) added realpath.
287 - (libeio) added fallocate.
288 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
289 - (libeio) do not acquire any locks when forking.

291
2923.93 Wed Jun 29 23:44:18 CEST 2011
293 - ECB.H WAS MISSING.
294
2953.92 Wed Jun 29 14:45:41 CEST 2011
296 - ecb.h was missing.
297
2983.91 Wed Jun 29 13:24:42 CEST 2011
299 - (libeio) work around a Linux (and likely FreeBSD and other
300 kernels) bug where sendfile would not transfer all the requested
301 bytes on large transfers, using a heuristic.
302 - buggy sendfile caused aio_move/copy to sometimes fail for big
303 files (fortunately it checks that the whole file has been
304 transferred...)
305 - use libecb for higher performance and higher portability.
306 - (libeio) disable sendfile on darwin, it's too broken.
307 - disable fork tests on !linux, as only linux supports mixing
308 pthread and fork in perl.
309 - document the fact that fork doesn't work anymore when using
310 this module, on anything !GNU/Linux.
311 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
312 run on a 0.1MHz cpu. Or so.
313
3143.9 Fri May 27 02:43:47 CEST 2011
315 - (libeio) fix memory corruption in aio_readdirx for the flags
316 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
317 - add lots of newer POSIX and GNU/Linux-specific open
318 flags.
319
3203.8 Sun Mar 27 12:25:33 CEST 2011
321 - use nonstandard but maybe-working-on-bsd fork technique.
322 - support a max_idle value of 0.
323 - support setting of idle timeout value (IO::AIO::idle_timeout).
324
3253.72 Fri Feb 11 04:25:38 CET 2011
326 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
327 - aio_mknod always used a dev_t value of 0.
328 - new treescan option: --grep.
329 - add more S_IF macros, and major/minor/makedev "macros".
330
3313.71 Thu Dec 30 08:18:46 CET 2010
332 - the numerical result value passed to callbacks did not stringify
333 correctly, due to internal reuse and failure to reset the sv flags.
334 - actually test for posix_[mf]advise, as at least uClibc defines
335 _POSIX_ADVISORY_INFO without actually having any of the required
336 funcitonality. ugh.
337
3383.7 Mon Nov 1 23:00:34 CET 2010
339 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
340 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
341 - document the sad state of affairs w.r.t. pthread on many bsds.
342 - do not enable mmap on systems without _POSIX_MAPPED_FILES
343 (openbsd 4.8).
344 - do not leak memory in IO::AIO::mmap when the scalar already
345 had string-data.
346 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
347 them.
348 - cache the result IV, for a minor speedup in the common case.
349 - croak when an mmapped-scalar changes location, to detect
350 user-errors better.
351 - fix aio_readlink prototype.
352
3533.65 Wed Mar 31 02:45:05 CEST 2010
354 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
355 cut off long pathnames in aio_readlink (based on patch by
356 Rasmus Andersson).
357 - a double fork partially killed the event pipe (great testcase
358 by dormando). affects IO::AIO, BDB and Async::Interrupt.
359 - suck steve's dick and rename our symbols to avoid colliding
360 with nonstandard identifier spam on the broken os x pseudo-os.
361 affects IO::AIO and BDB.
362
3633.6 Mon Jan 11 00:43:39 CET 2010
364 - (libeio) more fixes for the freebsd/apple sendfile - broken by
365 manpage standards, but apparently correct accoridng to actual
366 kernel sources.
367 - add IO::AIO::mmap/munmap support.
368 - add IO::AIO::m(un)lockall support.
369 - clean up manpage.
370
3713.5 Thu Jan 7 21:25:04 CET 2010
372 - (liebio) fix freebsd sendfile (Vanilla Hsu).
373 - (libeio) also fix darwin sendfile that suffered from a similar bug.
374 - add aio_statvfs as interface to statvfs/fstatvfs.
375 - work around buggy symlink() on cygwin in the testsuite.
376 - wtf. freebsd-8.0 actually passes the testsuite! I knew
377 they could implement fork and semaphores one day! cheers!
378
3793.4 Sat Jan 2 15:13:04 CET 2010
380 - (libeio) max_poll_time was not properly converted to ticks.
381 - clarify cancel_subs description.
382 - IO::AIO::sendfile did not actually return the return value
383 from the sendfile call.
384 - implement aio_msync, aio_mtouch.
385 - (libeio) tentatively support darwin in sendfile.
386
3873.31 Thu Nov 12 02:14:29 CET 2009
388 - fix result status documentation of aio_copy, aio_move.
389 - speed up object creation considerably by avoiding
390 hash lookups.
391
3923.3 Wed Aug 5 13:52:58 CEST 2009
393 - use common::sense.
394 - use common schmorp.h header.
395 - allow integers (file descriptors) in addition to file handles.
396 - take advantage of linux' eventfd (but it seems slower on smp?).
397 - use poll not select on posix platforms.
398
3993.261 Wed Jul 1 10:11:51 CEST 2009
400 - more 0S X workarounds (patch by Tokuhiro Matsuno).
401
4023.26 Tue Jun 30 09:33:26 CEST 2009
403 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
404 try to work around this horribly broken OS in a somewhat hackish
405 way. might help other os's too.
406
4073.25 Sat Jun 27 05:18:26 CEST 2009
408 - added IO::AIO::fadvise and IO::AIO::sendfile.
409 - (libeio) replaced quicksort+insertion sort by a tuned radix
410 sort + insertion sort, resulting in comparable runtime (usually
411 faster) to the old version, but without any ill side effects on
412 degenerated (for quicksort) data.
413 - (libeio) correctly sort dirs by inodes if we have perfect type
414 knowledge and DIRS_FIRST is used.
415 - (libeio) internally the wrong DT_* constants were used, but no
416 known system has differing EIO_DT_*/DT_* values, so not an issue.
417 - removed a (harmless) assert that was left over on the code
418 but should not have been.
419 - use more correct types (change IO length from IV to VAL64,
420 which makes a difference on systems without 64 bit perls).
421
4223.23 Sat Jun 13 16:57:58 CEST 2009
423 - fix off-by-one bug in aio_readdir that was introduced in the
424 rushed 3.22 release.
425
4263.22 Sat Jun 13 15:32:40 CEST 2009
427 - speed up readdirx sort algorithm slightly.
428 - bin/treescan was missing from distro tarball.
429
4303.21 Fri Jun 12 18:45:53 CEST 2009
431 - new options --dirs and --files for treescan.
432 - install bin/treescan by default.
433 - (libeio) aio_readdir can now be cancelled while executing.
434 - fix a printf format string for 64 bit systems (could lead
435 to problems on big endian 64 bit systems).
436 - do not use qsort() but our own algorithm: glibc initialises
437 the whole locale and I/O subsystem inside qsort, causing
438 a stack overflow on 32 bit machines. The new sort uses much less
439 stack and is more than twice as fast in typical situations.
440
4413.2 Sun Jun 7 20:30:05 CEST 2009
442 - (libeio) pwrite emulation was even more flawed than intended and did
443 not restore the file offset.
444 - add aio_readdirx, which can return inode and filetype and sort
445 the names in various ways.
446 - unfortunately, utime, chmod, chown on an open file that has just
447 been written can easily block, which caused aio_copy to block the
448 process. no more!
449 - no longer rely on dst path in aio_copy when futime is available.
450
4513.19 Tue Apr 21 22:05:21 CEST 2009
452 - more perl 5.10 workarounds for aio_read and write.
453 - aio_write no longer modifies the sv (if possible).
454 - aio_read now works correctly with magic values.
455
4563.18 Sun Apr 19 21:17:32 CEST 2009
457 - better diagnostics when some aio_* functions get passed an illegal fh.
458 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
459
4603.17 Thu Nov 20 08:45:36 CET 2008
461 - (libeio) added aio_sync_file_range (untested).
462 - add aio_busy to @IO::AIO::AIO_REQ.
463
4643.16 Wed Oct 22 18:28:01 CEST 2008
465 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
466 part to improve portability to perl 5.8 (reported by szymon).
467
4683.15 Mon Oct 13 00:39:55 CEST 2008
469 - automatic removal of feeders was broken.
470 - (libeio) use a more robust method to detect whether a feeder
471 has added something to the group or not.
472
4733.1 Thu Oct 2 13:34:40 CEST 2008
474 - pre-deref the passed callback object, for increased speed
475 and decreased memory usage.
476 - call on_next_submit callback even for aio_group - impact unknown,
477 but seems more correct.
478 - $req->cb now returns the original callback.
479 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
480 requiring a thread switch.
481 - (libeio) status code of aio_futime and aio_utime was always passed 0.
482 - do some other ยต-optimisations.
483
4843.07 Sat Aug 2 16:06:13 CEST 2008
485 - do not include LIBS in autoconf tests.
486
4873.06 Tue Jul 15 12:41:32 CEST 2008
488 - move preadwritelock definition before it's first reference,
489 to make it compile again on broken platforms (they still exist)
490 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
491
4923.05 Thu Jun 19 23:23:52 CEST 2008
493 - work around perl overriding readdir etc. with thread-unsafe
494 (sic!) versions.
495
4963.04 Wed Jun 18 01:35:38 CEST 2008
497 - (libeio) fix eio_mknod, which confused it's arguments.
498 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
499 is stupid.
500 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
501 - (libeio) fix a bug that could potentially cause IO::AIO
502 not to get initialised properly.
503
5043.03 Thu May 29 05:33:30 CEST 2008
505 - (libeio) correctly call pthread_attr_destroy ().
506 - (libeio) work around broken bsd headers once more.
507 - reduce shared library size again by not including wrappers.
508 - max_outstanding could cause poll to enter a busy-waiting loop.
509 - document the new IO::AIO::poll_cb result value.
510
5113.02 Mon May 12 02:32:02 CEST 2008
512 - fix a memory leak on aio_readlink.
513 - bring back working fchmod.
514 - nop and busy now set result to 0.
515 - set errno to ENOMEM when allocation fails.
516
5173.01 Sun May 11 03:07:03 CEST 2008
518 - (libeio) make it compile on systems without readahead or readdir_r.
519 - (libeio) improve configure check for readahead availability.
520 - do not try to link against -lrt.
521 - use a separate configure script for IO::AIO (not the libeio one).
522
5233.0 Sun May 11 00:57:14 CEST 2008
524 - added bin/treescan to the distribution.
525 - switched to using libeio.
526 - LOTS OF INCOMPATIBLE CHANGES:
527 - remove signal functionality, it is not worth the effort.
528 - max_outstanding no longer returns the previous number of requests.
529 - poll_cb no longer returns number of requests.
530
5312.62 Sat Apr 26 13:59:33 CEST 2008
532 - port to solaris perls configured for old posix
533 (analysed by Jost Krieger).
534 - keep a reference to the perl filehandle object in aio_close,
535 so it doesn't get closed prematurely, leading to ugly races.
536
5372.61 Wed Apr 16 18:45:02 CEST 2008
538 - fix treescan output duplication and improve output ordering.
539 also display files given on the commandline.
540 - use a different algorithm for aio_close that is faster
541 and probably has even lower chances of blocking.
542 - do our own stack memory management for threads - linux
543 allocates outrageous amounts of VM (not so bad unless you
544 use mlockall...), which severely limits the number of threads
545 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
546 and 4096 * sizeof (long) (usually this is 16..64k).
547
5482.6 Sun Mar 30 08:28:11 CEST 2008
549 - added aio_sync.
550 - added aio_pathsync.
551 - fix prototypes of (void) functions.
552
5532.51 Sat Oct 6 16:04:54 CEST 2007
554 - perlio isn't generally threadsafe, so aio_close could not work reliably.
555 aio_close now tries a safe hack that might not be that asynchronous
556 (see the manpage for details).
557 - discard callback return values as to not grow the stack endlessly
558 when poll_cb handles many requests without returning.
559 - minor code cleanups.
560
5612.5 Thu Oct 4 14:49:08 CEST 2007
562 - replaced _fd2fh with faster xs code.
563 - aio_close will now try to do "the right thing" and thus might
564 work sensibly for the very first time.
565
5662.41 Mon Sep 24 21:28:21 CEST 2007
567 - after fork, invest some work to make sure that the poll_fileno
568 stays stable (by dup2'ing the new fd over the old one), to make
569 it easier for programs/libs that don't control their forking
570 behaviour and cannot recreate their watchers.
571
5722.4 Sun Aug 5 18:44:22 CEST 2007
573 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
574 successfully demonstrated that you can block on futimes...).
575 - allow undef as fileoffset for aio_read/write and use read/write(2)
576 internally (useful for sockets or O_APPEND handles).
577 - allow undef for length in aio_write.
578 - negative dataoffsets work as expected now in aio_read/aio_write.
579 - use NV instead of UV for 32 bit perls and file offsets, as NVs
580 have a larger range then.
581 - shared code between BDB and IO::AIO.
582 - aio_busy was completely broken. now fixed.
583 - readahead emulation now returns something.
584 - correctly set errno to ENOSYS on unimplemented functions
585 (should never happen, though).
586 - large changes to make it partially compile and run on win32,
587 but win32 lacks too much functionality, and perl overrides way
588 too many functions with crashing versions.

92.33 Tue Jan 23 23:55:41 CET 2007 5902.33 Tue Jan 23 23:55:41 CET 2007
10 - fix install path (Andreas J. Koenig). 591 - fix install path (Andreas J. Koenig).
