40
414.72 Wed Apr 3 04:56:03 CEST 2019
42 - (libeio) if fd 0 is available do not use it for aio_wd, as it
43 collides with IO::AIO::CWD.
44 - added IO::AIO::memfd_create.
45 - correctly include <sys/uio.h> in the vmsplice test.
46 - reduce codesize by ~7% on amd64 by declaring more functions
47 as noinline.
48 - documentation fixes and updates.
49 - experimental and undocumented preliminary support for synchronous statx.
50
514.71 Sun Mar 10 13:09:26 CET 2019
52 - due to an error in the linux manpages, the configure tests
53 for readahead, sync_file_range, splice etc. failed. This has been fixed.
54
554.7 Mon Mar 4 11:28:13 CET 2019
56 - majorly speed up scandir for the very special case of a non-POSIX
57 filesystem that nevertheless reports valid dt_type information.
58 The only known filesystem of this type is currently btrfs, which
59 didn't get it's act together to implement POSIX semantics in all
60 these years, and I am tired of waiting.
61 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
62 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
63 were detected by autoconf.
64
654.6 Sat Aug 25 21:58:36 CEST 2018
66 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
67 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
68 but only st_gen on openbsd because they compiled their perl without support
69 for birthtimes).
70 - fix madvise and munlock to properly support negative offsets.
71 - allocate fd for the aio_close at boot time, to guarantee it working
72 later, rather than calling abort when it fails. also avoids
73 close-on-exec race issues after module load.
74 - #undef utime on win32, maybe this helps some reports of utime hangs.
75 - minor doc improvements.
76 - minor configure cleanups.
77 - use $Config{perllibs} instead of libs for configure. might help people
78 who didn't install all perl dependencies (might break things as well).
79
804.54 Tue Aug 14 13:54:48 CEST 2018
81 - include sys/mkdev.h or sys/sysmacros.h if available.
82 - further tweaks to configure invocation for systems requiring --rpath.
83 - no longer rely on custom paths on win32 platforms.
84 - try to work around buggy PAGESIZE macro on solaris.
85
864.53 Tue Aug 14 11:27:50 CEST 2018
87 - add $Config{libs} to LIBS for configure, to work around systems
88 with broken library dependencies (... openbsd).
89
904.52 Sun Aug 12 08:09:45 CEST 2018
91 - config.h.in was missing in distribution.
92
934.51 Sun Aug 12 07:24:14 CEST 2018
94 - complete rework of the autoconf framework: IO::AIO now uses its own
95 config.h, separate from libeio, and tries to test the actual perl
96 environment, not the standard system environment.
97 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
98 stat functions.
99 - removed non-portable C++ syntax from eio.c.
100 - try to fix readdir tests on cygwin spuriously failing.
101
1024.5 Wed Aug 1 00:23:55 CEST 2018
103 - aio_mtouch touch all pages as requested, not just the first page in most cases.
104 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
105 and MREMAP_FIXED.
106 - add O_ACCMODE.
107 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
108
1094.4 Tue Feb 20 07:54:12 CET 2018
110 - new aio_slurp request.
111 - add (experimental) IO::AIO::eventfd and timerfd* function.
112 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
113 - point out that aio_copy overwrites existing files.
114 - removed filesystem magic number table from aio_statvfs docs as
115 statvfs doesn't actually return this info at all (statfs does).
116 - add a bunch of (mostly linux-specific) constants for use in ioctls
117 (see aio_ioctl docs).
118 - treescan now has a proper manpage and useful --help output.
119 - new option --sync in treescan, to sync everything in a subtree.
120 - changed default for aio_msync flags to MSYNC_SYNC.
121 - document offset/length behaviour of mprotect/madvise.
122 - support linux's renameat2 (via aio_rename2).
123 - add aio_rename2, an aio_rename with flags.
124 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
125 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
126 - (libeio) use posix_close if available.
127 - (libeio) internal close() calls no longer disturb errno.
128 - add IO:AIO::FALLOC_FL_UNSHARE.
129 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
130 and better eventfd detection.
131
1324.34 Sun May 1 19:18:24 CEST 2016
133 - def0.h was not properly generated during previous release, causing
134 compile errors on various platforms.
135 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
136 - removed duplicate definition of MAP_HUGETLB, that was found due to
137 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
138 - added (untested!) aio_fcntl, aio_ioctl requests.
139 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
140 as manpages-dev originally claimed.
141
1424.33 Mon Jan 18 12:50:10 CET 2016
143 - add IO::AIO::pipe2 function.
144 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
145 constants.
146 - added support for O_TMPFILE and O_PATH constants.
147 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
148 consdtants, whether they can be sensibly used or not.
149 - use NO_INIT where applicable.
150 - update libecb.
151 - added stability canary support.
152 - updated linux super magic table to 4.3.3.
153
1544.32 Wed Feb 11 20:32:11 CET 2015
155 - replace off_t by STRLEN where appropriate, should not result in
156 user-visible changes.
157 - update ecb.h for C11 compatibility.
158
1594.31 Tue Jun 3 03:29:27 CEST 2014
160 - work around more 5.20 bugs. backwards compatibility my ass.
161
1624.3 Fri Apr 11 06:22:38 CEST 2014
163 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
164 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
165 in 5.18. What's so attractive about giving a shit about backwards
166 compatibility - I will never understand.
167
1684.2 Sat Jan 25 01:13:14 CET 2014
169 - aio_group could corrupt memory because it didn't restore
170 the stack after req_submit.
171 - be more careful on (e.g. permission) errors in bin/treescan.
172 - work around changes in ExtUtils::MakeMaker.
173 - (libeio) implement aio_realpath for win32.
174 - (xthread) work around compile time bugs in ptw32.
175 - added IO::AIO::pipesize.
176 - (libecb) insignificant update.
177
1784.19 Sun Jan 6 12:47:26 CET 2013
179 - avoid endless loop in fiemap with some XFS files.
180 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
181 and call rename/rmdir instead of renameat/unlinkat.
182
1834.18 Thu Oct 11 07:01:26 CEST 2012
184 - fix unintended xthread_create by intentionalising it :)
185
1864.17 Thu Oct 11 05:19:47 CEST 2012
187 - rename aio_fallocate to aio_allocate, to match documentation.
188 - add list of linux fsid values to aio_statvfs docs.
189 - work around a bug in btrfs' FIEMAP ioctl implementation.
190 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
191 as per unix spec.
192
1934.16 Tue Aug 14 05:39:03 CEST 2012
194 - aio_statvfs was wromgly marked for wd emulation, causing
195 it to malfunction for paths.
196 - fix a crash in aio_fiemap, when used on ranges without any
197 extents.
198 - work around linux kernel bug (at least in 3.2): kernel might
199 trash fiemap input arguments.
200 - work around linux kernel bug (at least in 3.2): kernel does not
201 set FIEMAP_EXTENT_LAST on last segment.
202 - work around linux kernel bug (at least in 3.2): kernel silently
203 truncates segment count if a file.
204 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
205 to quick overview.
206 - splice can corrupt data.
207 - (libeio) remove pread/pwrite emulation.
208 - do not grow mmaped scalars in aio_read.
209 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
210 - provide pread/pwrite for win32, making it link again on native win32.
211
2124.15 Tue Apr 10 06:59:00 CEST 2012
213 - always include linux/types.h for fiemap, for compatibility to
214 ancient systems (Paul Howarth).
215 - experimental support for IO::AIO::splice and ::tee (no aio_...).
216 - provide SEEK_HOLE and SEEK_DATA, if available.
217 - work around (again!) an immensely stupid bug in RHEL, defining
218 autoconf macros in linux system headers (analysed by Paul Howarth).
219
2204.14 Sat Apr 7 02:45:18 CEST 2012
221 - fix stat structure usage on windows, which caused bogus stat results.
222 - (libeio) make readahead emulation behave more like actual readahead by never failing.
223 - new request aio_seek.
224 - new request aio_fiemap.
225 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
226
2274.12 Fri Dec 30 08:51:25 CET 2011
228 - realpath would return a random value if the name was too long,
229 instead of -1.
230 - port to c89.
231
2324.11 Mon Oct 10 00:24:11 CEST 2011
233 - libeio didn't compile on !linux (Paul Howarth).
234
2354.1 Sun Oct 9 10:24:11 CEST 2011
236 - IO::AIO did access uninitialised memory on unsuccessful stats.
237 - (libeio) added syncfs syscall wrapper.
238 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
239 - (libeio) support multiple indepenent working directories.
240 - applied speling corrections by Nicholas Bamber.
241 - tune treescan #threads and #outstanding requests a bit.
242 - reduce the number of file descriptors in use at any one time
243 in treescan, to avoid running out of them (and using too much ram).
244 - take advantage of working directoriy abstractions
245 in aio_scandir and treescan.
246 - reduce compiled size by ~10% by not inlining some key functionality.
247 - added --progress switch to treescan.
248
2494.0 Mon Jul 18 05:01:10 CEST 2011
250 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
251 see FORK BEHAVIOUR in manpage for details.
252 - passes testsuite on win32 now and may actually work
253 (activestate 5.10.1 / MSVC6, YMMV).
254 - (libeio) fix a deadlock where a wakeup signal could be missed when
255 a timeout occured at the same time.
256 - (libeio) added realpath.
257 - (libeio) added fallocate.
258 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
259 - (libeio) do not acquire any locks when forking.
260 - (libeio) use fewer time() syscalls when waiting for new requests.
261
2623.93 Wed Jun 29 23:44:18 CEST 2011
263 - ECB.H WAS MISSING.
264
2653.92 Wed Jun 29 14:45:41 CEST 2011
266 - ecb.h was missing.
267
2683.91 Wed Jun 29 13:24:42 CEST 2011
269 - (libeio) work around a Linux (and likely FreeBSD and other
270 kernels) bug where sendfile would not transfer all the requested
271 bytes on large transfers, using a heuristic.
272 - buggy sendfile caused aio_move/copy to sometimes fail for big
273 files (fortunately it checks that the whole file has been
274 transferred...)
275 - use libecb for higher performance and higher portability.
276 - (libeio) disable sendfile on darwin, it's too broken.
277 - disable fork tests on !linux, as only linux supports mixing
278 pthread and fork in perl.
279 - document the fact that fork doesn't work anymore when using
280 this module, on anything !GNU/Linux.
281 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
282 run on a 0.1MHz cpu. Or so.
283
2843.9 Fri May 27 02:43:47 CEST 2011
285 - (libeio) fix memory corruption in aio_readdirx for the flags
286 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
287 - add lots of newer POSIX and GNU/Linux-specific open
288 flags.
289
2903.8 Sun Mar 27 12:25:33 CEST 2011
291 - use nonstandard but maybe-working-on-bsd fork technique.
292 - support a max_idle value of 0.
293 - support setting of idle timeout value (IO::AIO::idle_timeout).
294
2953.72 Fri Feb 11 04:25:38 CET 2011
296 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
297 - aio_mknod always used a dev_t value of 0.
298 - new treescan option: --grep.
299 - add more S_IF macros, and major/minor/makedev "macros".
300
3013.71 Thu Dec 30 08:18:46 CET 2010
302 - the numerical result value passed to callbacks did not stringify
303 correctly, due to internal reuse and failure to reset the sv flags.
304 - actually test for posix_[mf]advise, as at least uClibc defines
305 _POSIX_ADVISORY_INFO without actually having any of the required
306 funcitonality. ugh.
307
3083.7 Mon Nov 1 23:00:34 CET 2010
309 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
310 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
311 - document the sad state of affairs w.r.t. pthread on many bsds.
312 - do not enable mmap on systems without _POSIX_MAPPED_FILES
313 (openbsd 4.8).
314 - do not leak memory in IO::AIO::mmap when the scalar already
315 had string-data.
316 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
317 them.
318 - cache the result IV, for a minor speedup in the common case.
319 - croak when an mmapped-scalar changes location, to detect
320 user-errors better.
321 - fix aio_readlink prototype.
322
3233.65 Wed Mar 31 02:45:05 CEST 2010
324 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
325 cut off long pathnames in aio_readlink (based on patch by
326 Rasmus Andersson).
327 - a double fork partially killed the event pipe (great testcase
328 by dormando). affects IO::AIO, BDB and Async::Interrupt.
329 - suck steve's dick and rename our symbols to avoid colliding
330 with nonstandard identifier spam on the broken os x pseudo-os.
331 affects IO::AIO and BDB.
332
3333.6 Mon Jan 11 00:43:39 CET 2010
334 - (libeio) more fixes for the freebsd/apple sendfile - broken by
335 manpage standards, but apparently correct accoridng to actual
336 kernel sources.
337 - add IO::AIO::mmap/munmap support.
338 - add IO::AIO::m(un)lockall support.
339 - clean up manpage.
340
3413.5 Thu Jan 7 21:25:04 CET 2010
342 - (liebio) fix freebsd sendfile (Vanilla Hsu).
343 - (libeio) also fix darwin sendfile that suffered from a similar bug.
344 - add aio_statvfs as interface to statvfs/fstatvfs.
345 - work around buggy symlink() on cygwin in the testsuite.
346 - wtf. freebsd-8.0 actually passes the testsuite! I knew
347 they could implement fork and semaphores one day! cheers!
348
3493.4 Sat Jan 2 15:13:04 CET 2010
350 - (libeio) max_poll_time was not properly converted to ticks.
351 - clarify cancel_subs description.
352 - IO::AIO::sendfile did not actually return the return value
353 from the sendfile call.
354 - implement aio_msync, aio_mtouch.
355 - (libeio) tentatively support darwin in sendfile.
356
3573.31 Thu Nov 12 02:14:29 CET 2009
358 - fix result status documentation of aio_copy, aio_move.
359 - speed up object creation considerably by avoiding
360 hash lookups.
361
3623.3 Wed Aug 5 13:52:58 CEST 2009
363 - use common::sense.
364 - use common schmorp.h header.
365 - allow integers (file descriptors) in addition to file handles.
366 - take advantage of linux' eventfd (but it seems slower on smp?).
367 - use poll not select on posix platforms.
368
3693.261 Wed Jul 1 10:11:51 CEST 2009
370 - more 0S X workarounds (patch by Tokuhiro Matsuno).
371
3723.26 Tue Jun 30 09:33:26 CEST 2009
373 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
374 try to work around this horribly broken OS in a somewhat hackish
375 way. might help other os's too.
376
3773.25 Sat Jun 27 05:18:26 CEST 2009
378 - added IO::AIO::fadvise and IO::AIO::sendfile.
379 - (libeio) replaced quicksort+insertion sort by a tuned radix
380 sort + insertion sort, resulting in comparable runtime (usually
381 faster) to the old version, but without any ill side effects on
382 degenerated (for quicksort) data.
383 - (libeio) correctly sort dirs by inodes if we have perfect type
384 knowledge and DIRS_FIRST is used.
385 - (libeio) internally the wrong DT_* constants were used, but no
386 known system has differing EIO_DT_*/DT_* values, so not an issue.
387 - removed a (harmless) assert that was left over on the code
388 but should not have been.
389 - use more correct types (change IO length from IV to VAL64,
390 which makes a difference on systems without 64 bit perls).
391
3923.23 Sat Jun 13 16:57:58 CEST 2009
393 - fix off-by-one bug in aio_readdir that was introduced in the
394 rushed 3.22 release.
395
3963.22 Sat Jun 13 15:32:40 CEST 2009
397 - speed up readdirx sort algorithm slightly.
398 - bin/treescan was missing from distro tarball.
399
4003.21 Fri Jun 12 18:45:53 CEST 2009
401 - new options --dirs and --files for treescan.
402 - install bin/treescan by default.
403 - (libeio) aio_readdir can now be cancelled while executing.
404 - fix a printf format string for 64 bit systems (could lead
405 to problems on big endian 64 bit systems).
406 - do not use qsort() but our own algorithm: glibc initialises
407 the whole locale and I/O subsystem inside qsort, causing
408 a stack overflow on 32 bit machines. The new sort uses much less
409 stack and is more than twice as fast in typical situations.
410
4113.2 Sun Jun 7 20:30:05 CEST 2009
412 - (libeio) pwrite emulation was even more flawed than intended and did
413 not restore the file offset.
414 - add aio_readdirx, which can return inode and filetype and sort
415 the names in various ways.
416 - unfortunately, utime, chmod, chown on an open file that has just
417 been written can easily block, which caused aio_copy to block the
418 process. no more!
419 - no longer rely on dst path in aio_copy when futime is available.
420
4213.19 Tue Apr 21 22:05:21 CEST 2009
422 - more perl 5.10 workarounds for aio_read and write.
423 - aio_write no longer modifies the sv (if possible).
424 - aio_read now works correctly with magic values.
425
4263.18 Sun Apr 19 21:17:32 CEST 2009
427 - better diagnostics when some aio_* functions get passed an illegal fh.
428 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
429
4303.17 Thu Nov 20 08:45:36 CET 2008
431 - (libeio) added aio_sync_file_range (untested).
432 - add aio_busy to @IO::AIO::AIO_REQ.
433
4343.16 Wed Oct 22 18:28:01 CEST 2008
435 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
436 part to improve portability to perl 5.8 (reported by szymon).
437
4383.15 Mon Oct 13 00:39:55 CEST 2008
439 - automatic removal of feeders was broken.
440 - (libeio) use a more robust method to detect whether a feeder
441 has added something to the group or not.
442
4433.1 Thu Oct 2 13:34:40 CEST 2008
444 - pre-deref the passed callback object, for increased speed
445 and decreased memory usage.
446 - call on_next_submit callback even for aio_group - impact unknown,
447 but seems more correct.
448 - $req->cb now returns the original callback.
449 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
450 requiring a thread switch.
451 - (libeio) status code of aio_futime and aio_utime was always passed 0.
452 - do some other ยต-optimisations.
453
4543.07 Sat Aug 2 16:06:13 CEST 2008
455 - do not include LIBS in autoconf tests.
456
4573.06 Tue Jul 15 12:41:32 CEST 2008
458 - move preadwritelock definition before it's first reference,
459 to make it compile again on broken platforms (they still exist)
460 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
461
4623.05 Thu Jun 19 23:23:52 CEST 2008
463 - work around perl overriding readdir etc. with thread-unsafe
464 (sic!) versions.
465
4663.04 Wed Jun 18 01:35:38 CEST 2008
467 - (libeio) fix eio_mknod, which confused it's arguments.
468 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
469 is stupid.
470 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
471 - (libeio) fix a bug that could potentially cause IO::AIO
472 not to get initialised properly.
473
4743.03 Thu May 29 05:33:30 CEST 2008
475 - (libeio) correctly call pthread_attr_destroy ().
476 - (libeio) work around broken bsd headers once more.
477 - reduce shared library size again by not including wrappers.
478 - max_outstanding could cause poll to enter a busy-waiting loop.
479 - document the new IO::AIO::poll_cb result value.
480
4813.02 Mon May 12 02:32:02 CEST 2008
482 - fix a memory leak on aio_readlink.
483 - bring back working fchmod.
484 - nop and busy now set result to 0.
485 - set errno to ENOMEM when allocation fails.
486
4873.01 Sun May 11 03:07:03 CEST 2008
488 - (libeio) make it compile on systems without readahead or readdir_r.
489 - (libeio) improve configure check for readahead availability.
490 - do not try to link against -lrt.
491 - use a separate configure script for IO::AIO (not the libeio one).
492
4933.0 Sun May 11 00:57:14 CEST 2008
494 - added bin/treescan to the distribution.
495 - switched to using libeio.
496 - LOTS OF INCOMPATIBLE CHANGES:
497 - remove signal functionality, it is not worth the effort.
498 - max_outstanding no longer returns the previous number of requests.
499 - poll_cb no longer returns number of requests.
500
5012.62 Sat Apr 26 13:59:33 CEST 2008
502 - port to solaris perls configured for old posix
503 (analysed by Jost Krieger).
504 - keep a reference to the perl filehandle object in aio_close,
505 so it doesn't get closed prematurely, leading to ugly races.
506
5072.61 Wed Apr 16 18:45:02 CEST 2008
508 - fix treescan output duplication and improve output ordering.
509 also display files given on the commandline.
510 - use a different algorithm for aio_close that is faster
511 and probably has even lower chances of blocking.
512 - do our own stack memory management for threads - linux
513 allocates outrageous amounts of VM (not so bad unless you
514 use mlockall...), which severely limits the number of threads
515 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
516 and 4096 * sizeof (long) (usually this is 16..64k).
517
5182.6 Sun Mar 30 08:28:11 CEST 2008
519 - added aio_sync.
520 - added aio_pathsync.
521 - fix prototypes of (void) functions.
522
5232.51 Sat Oct 6 16:04:54 CEST 2007
524 - perlio isn't generally threadsafe, so aio_close could not work reliably.
525 aio_close now tries a safe hack that might not be that asynchronous
526 (see the manpage for details).
527 - discard callback return values as to not grow the stack endlessly
528 when poll_cb handles many requests without returning.
529 - minor code cleanups.
530
5312.5 Thu Oct 4 14:49:08 CEST 2007
532 - replaced _fd2fh with faster xs code.
533 - aio_close will now try to do "the right thing" and thus might
534 work sensibly for the very first time.
535
5362.41 Mon Sep 24 21:28:21 CEST 2007
537 - after fork, invest some work to make sure that the poll_fileno
538 stays stable (by dup2'ing the new fd over the old one), to make
539 it easier for programs/libs that don't control their forking
540 behaviour and cannot recreate their watchers.
541
5422.4 Sun Aug 5 18:44:22 CEST 2007
543 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
544 successfully demonstrated that you can block on futimes...).
545 - allow undef as fileoffset for aio_read/write and use read/write(2)
546 internally (useful for sockets or O_APPEND handles).
547 - allow undef for length in aio_write.
548 - negative dataoffsets work as expected now in aio_read/aio_write.
549 - use NV instead of UV for 32 bit perls and file offsets, as NVs
550 have a larger range then.
551 - shared code between BDB and IO::AIO.
552 - aio_busy was completely broken. now fixed.
553 - readahead emulation now returns something.
554 - correctly set errno to ENOSYS on unimplemented functions
555 (should never happen, though).
556 - large changes to make it partially compile and run on win32,
557 but win32 lacks too much functionality, and perl overrides way
558 too many functions with crashing versions.
559
5602.33 Tue Jan 23 23:55:41 CET 2007
561 - fix install path (Andreas J. Koenig).
562
5632.32 Mon Jan 22 16:56:23 CET 2007
564 - added aio_rmtree.
565 - wow, aio_mkdir was missing.
566 - aio_load did return undef on error, not -1.
567 - use prefixexp not prefix in autoconf.pm
568 (suggested by ... rt.cpan.org unreachable).
569 - avoid installing autoconf.pm.
570
5712.31 Sat Jan 6 03:46:02 CET 2007
572 - added aio_load.
573
5742.3 Sat Dec 23 05:48:07 CET 2006
575 - fix off-by-one bug in aio_read, causing memory corruption
576 or crashes.
577
5782.21 Fri Dec 22 05:03:38 CET 2006
579 - minor doc updates.
580 - minor cleanups.
581 - IO::AIO::poll returns request count.
582 - undocumented and unfinished async-signal-reporting.
583
5842.2 Tue Oct 31 00:31:00 CET 2006
585 - minor doc updates.
586 - added aio_readlink.
587 - properly zero-terminate aio_read buffer.
588 - fix aio_read/write with nonzero dataoffset.
589 - reduced size of aio request structure.
590 - better diagnostics when pathnames etc. are not byte-encoded;
591 do not leak request in that case, either.
592
5932.1 Sun Oct 29 02:01:57 CET 2006
594 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
595 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
8 - fix a bug in aio_move where it would fail everytime 596 - fix a bug in aio_move where it would fail everytime
9 it would have to copy files manually. 597 it would have to copy files manually.
598 - doc updates.
10 - start threads only on (very low) demand. 599 - start threads only on (very low) demand.
11 - end threads automatically after 10s idle. 600 - end superfluous threads automatically after 10s idling.
601 - add IO::AIO::max_idle to control this.
12 - some tuning applied to random places. 602 - some tuning applied to random places.
13 - add aio_mknod. 603 - add aio_mknod.
14 604
152.0 Thu Oct 26 18:27:58 CEST 2006 6052.0 Thu Oct 26 18:27:58 CEST 2006
16 - minor incompatibility: max_outstanding semantics have changed. 606 - minor incompatibility: max_outstanding semantics have changed.
