48
49 - aio_copy now tries to preallocate the4 destination file.
50
514.80 Sat 01 Apr 2023 04:13:37 CEST
52 - remove long obsolete "paths must be absolute" text in aio_open/stat
53 descriptions.
54 - another workaround for the low-quality musl libc.
55 - test for umount seperately, as it is more portable.
56 - some low-quality posix attempts (openbsd, osx) declare the availability
57 of fexecve but then don't even bother to implemnent a stub.
58
594.79 Sun 25 Sep 2022 18:25:53 CEST
60 - the autoconf result of the mount check was not used, so it failed to
61 compile on most systems (reported by crackoff@tutanota.com).
62 - work around fedora not having a working C compiler setup by design
63 (reported by Paul Howarth).
64
654.78 Tue 06 Sep 2022 12:54:43 CEST
66 - add IO::AIO::mount and IO::AIO::umount.
67 - add a bunch of symbols from sys/mount.h.
68
694.77 Mon 05 Sep 2022 02:03:38 CEST
70 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
71 - add fexecve.
72 - add lots of missing functions to @EXPORT_OK.
73
744.76 Tue Jul 27 20:45:01 CEST 2021
75 - add autoconf test for siginfo_t, which is, of course, not
76 available on windows (reported by Peter Petky).
77 - disable syscalls on solaris, as perl seems to provide an
78 incompatible syscall prototype that clashes with sys/syscall.h.
79 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
80 MAP_UNINITIALIZED.
81
824.75 Wed Dec 30 08:44:55 CET 2020
83 - removed leftover debug output from treescan.
84 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
85 FSCONFIG_*, MOUNT_ATTR_* constants.
86
874.74 Tue Dec 29 16:19:28 CET 2020
88 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
89 - rework bin/treescan to avoid recursion. This fixes two bugs
90 where a deep directory traversal or a lot of command line
91 arguments could cause it to crash.
92 - added (but not documented) open_tree, AT_* and move_mount flags.
93 - support defining syscall numbers in gendef0.
94
954.73 Fri Dec 4 02:08:37 CET 2020
96 - def0.h was not uptodate, running into musl problems
97 (reported by B Fraser).
98 - IO::AIO::splice and IO::AIO::tee didn't properly return
99 64 bit values.
100 - added IO::AIO::accept4.
101 - add various F_SEAL related fcntl constants.
102 - removed experimental marker for fdlimit functions.
103 - fiemap now includes the last segment even if it overflows
104 the end offset, which is arguably the correct behaviour.
105
1064.72 Wed Apr 3 04:56:03 CEST 2019
107 - (libeio) if fd 0 is available do not use it for aio_wd, as it
108 collides with IO::AIO::CWD.
109 - added IO::AIO::memfd_create.
110 - correctly include <sys/uio.h> in the vmsplice test.
111 - reduce codesize by ~7% on amd64 by declaring more functions
112 as noinline.
113 - documentation fixes and updates.
114 - experimental and undocumented preliminary support for synchronous statx.
115
1164.71 Sun Mar 10 13:09:26 CET 2019
117 - due to an error in the linux manpages, the configure tests
118 for readahead, sync_file_range, splice etc. failed. This has been fixed.
119
1204.7 Mon Mar 4 11:28:13 CET 2019
121 - majorly speed up scandir for the very special case of a non-POSIX
122 filesystem that nevertheless reports valid dt_type information.
123 The only known filesystem of this type is currently btrfs, which
124 didn't get it's act together to implement POSIX semantics in all
125 these years, and I am tired of waiting.
126 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
127 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
128 were detected by autoconf.
129
1304.6 Sat Aug 25 21:58:36 CEST 2018
131 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
132 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
133 but only st_gen on openbsd because they compiled their perl without support
134 for birthtimes).
135 - fix madvise and munlock to properly support negative offsets.
136 - allocate fd for the aio_close at boot time, to guarantee it working
137 later, rather than calling abort when it fails. also avoids
138 close-on-exec race issues after module load.
139 - #undef utime on win32, maybe this helps some reports of utime hangs.
140 - minor doc improvements.
141 - minor configure cleanups.
142 - use $Config{perllibs} instead of libs for configure. might help people
143 who didn't install all perl dependencies (might break things as well).
144
1454.54 Tue Aug 14 13:54:48 CEST 2018
146 - include sys/mkdev.h or sys/sysmacros.h if available.
147 - further tweaks to configure invocation for systems requiring --rpath.
148 - no longer rely on custom paths on win32 platforms.
149 - try to work around buggy PAGESIZE macro on solaris.
150
1514.53 Tue Aug 14 11:27:50 CEST 2018
152 - add $Config{libs} to LIBS for configure, to work around systems
153 with broken library dependencies (... openbsd).
154
1554.52 Sun Aug 12 08:09:45 CEST 2018
156 - config.h.in was missing in distribution.
157
1584.51 Sun Aug 12 07:24:14 CEST 2018
159 - complete rework of the autoconf framework: IO::AIO now uses its own
160 config.h, separate from libeio, and tries to test the actual perl
161 environment, not the standard system environment.
162 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
163 stat functions.
164 - removed non-portable C++ syntax from eio.c.
165 - try to fix readdir tests on cygwin spuriously failing.
166
1674.5 Wed Aug 1 00:23:55 CEST 2018
168 - aio_mtouch touch all pages as requested, not just the first page in most cases.
169 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
170 and MREMAP_FIXED.
171 - add O_ACCMODE.
172 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
173
1744.4 Tue Feb 20 07:54:12 CET 2018
175 - new aio_slurp request.
176 - add (experimental) IO::AIO::eventfd and timerfd* function.
177 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
178 - point out that aio_copy overwrites existing files.
179 - removed filesystem magic number table from aio_statvfs docs as
180 statvfs doesn't actually return this info at all (statfs does).
181 - add a bunch of (mostly linux-specific) constants for use in ioctls
182 (see aio_ioctl docs).
183 - treescan now has a proper manpage and useful --help output.
184 - new option --sync in treescan, to sync everything in a subtree.
185 - changed default for aio_msync flags to MSYNC_SYNC.
186 - document offset/length behaviour of mprotect/madvise.
187 - support linux's renameat2 (via aio_rename2).
188 - add aio_rename2, an aio_rename with flags.
189 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
190 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
191 - (libeio) use posix_close if available.
192 - (libeio) internal close() calls no longer disturb errno.
193 - add IO:AIO::FALLOC_FL_UNSHARE.
194 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
195 and better eventfd detection.
196
1974.34 Sun May 1 19:18:24 CEST 2016
198 - def0.h was not properly generated during previous release, causing
199 compile errors on various platforms.
200 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
201 - removed duplicate definition of MAP_HUGETLB, that was found due to
202 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
203 - added (untested!) aio_fcntl, aio_ioctl requests.
204 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
205 as manpages-dev originally claimed.
206
2074.33 Mon Jan 18 12:50:10 CET 2016
208 - add IO::AIO::pipe2 function.
209 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
210 constants.
211 - added support for O_TMPFILE and O_PATH constants.
212 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
213 consdtants, whether they can be sensibly used or not.
214 - use NO_INIT where applicable.
215 - update libecb.
216 - added stability canary support.
217 - updated linux super magic table to 4.3.3.
218
2194.32 Wed Feb 11 20:32:11 CET 2015
220 - replace off_t by STRLEN where appropriate, should not result in
221 user-visible changes.
222 - update ecb.h for C11 compatibility.
223
2244.31 Tue Jun 3 03:29:27 CEST 2014
225 - work around more 5.20 bugs. backwards compatibility my ass.
226
2274.3 Fri Apr 11 06:22:38 CEST 2014
228 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
229 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
230 in 5.18. What's so attractive about giving a shit about backwards
231 compatibility - I will never understand.
232
2334.2 Sat Jan 25 01:13:14 CET 2014
234 - aio_group could corrupt memory because it didn't restore
235 the stack after req_submit.
236 - be more careful on (e.g. permission) errors in bin/treescan.
237 - work around changes in ExtUtils::MakeMaker.
238 - (libeio) implement aio_realpath for win32.
239 - (xthread) work around compile time bugs in ptw32.
240 - added IO::AIO::pipesize.
241 - (libecb) insignificant update.
242
2434.19 Sun Jan 6 12:47:26 CET 2013
244 - avoid endless loop in fiemap with some XFS files.
245 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
246 and call rename/rmdir instead of renameat/unlinkat.
247
2484.18 Thu Oct 11 07:01:26 CEST 2012
249 - fix unintended xthread_create by intentionalising it :)
250
2514.17 Thu Oct 11 05:19:47 CEST 2012
252 - rename aio_fallocate to aio_allocate, to match documentation.
253 - add list of linux fsid values to aio_statvfs docs.
254 - work around a bug in btrfs' FIEMAP ioctl implementation.
255 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
256 as per unix spec.
257
2584.16 Tue Aug 14 05:39:03 CEST 2012
259 - aio_statvfs was wromgly marked for wd emulation, causing
260 it to malfunction for paths.
261 - fix a crash in aio_fiemap, when used on ranges without any
262 extents.
263 - work around linux kernel bug (at least in 3.2): kernel might
264 trash fiemap input arguments.
265 - work around linux kernel bug (at least in 3.2): kernel does not
266 set FIEMAP_EXTENT_LAST on last segment.
267 - work around linux kernel bug (at least in 3.2): kernel silently
268 truncates segment count if a file.
269 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
270 to quick overview.
271 - splice can corrupt data.
272 - (libeio) remove pread/pwrite emulation.
273 - do not grow mmaped scalars in aio_read.
274 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
275 - provide pread/pwrite for win32, making it link again on native win32.
276
2774.15 Tue Apr 10 06:59:00 CEST 2012
278 - always include linux/types.h for fiemap, for compatibility to
279 ancient systems (Paul Howarth).
280 - experimental support for IO::AIO::splice and ::tee (no aio_...).
281 - provide SEEK_HOLE and SEEK_DATA, if available.
282 - work around (again!) an immensely stupid bug in RHEL, defining
283 autoconf macros in linux system headers (analysed by Paul Howarth).
284
2854.14 Sat Apr 7 02:45:18 CEST 2012
286 - fix stat structure usage on windows, which caused bogus stat results.
287 - (libeio) make readahead emulation behave more like actual readahead by never failing.
288 - new request aio_seek.
289 - new request aio_fiemap.
290 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
291
2924.12 Fri Dec 30 08:51:25 CET 2011
293 - realpath would return a random value if the name was too long,
294 instead of -1.
295 - port to c89.
296
2974.11 Mon Oct 10 00:24:11 CEST 2011
298 - libeio didn't compile on !linux (Paul Howarth).
299
3004.1 Sun Oct 9 10:24:11 CEST 2011
301 - IO::AIO did access uninitialised memory on unsuccessful stats.
302 - (libeio) added syncfs syscall wrapper.
303 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
304 - (libeio) support multiple indepenent working directories.
305 - applied speling corrections by Nicholas Bamber.
306 - tune treescan #threads and #outstanding requests a bit.
307 - reduce the number of file descriptors in use at any one time
308 in treescan, to avoid running out of them (and using too much ram).
309 - take advantage of working directoriy abstractions
310 in aio_scandir and treescan.
311 - reduce compiled size by ~10% by not inlining some key functionality.
312 - added --progress switch to treescan.
313
3144.0 Mon Jul 18 05:01:10 CEST 2011
315 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
316 see FORK BEHAVIOUR in manpage for details.
317 - passes testsuite on win32 now and may actually work
318 (activestate 5.10.1 / MSVC6, YMMV).
319 - (libeio) fix a deadlock where a wakeup signal could be missed when
320 a timeout occured at the same time.
321 - (libeio) added realpath.
322 - (libeio) added fallocate.
323 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
324 - (libeio) do not acquire any locks when forking.
325 - (libeio) use fewer time() syscalls when waiting for new requests.
326
3273.93 Wed Jun 29 23:44:18 CEST 2011
328 - ECB.H WAS MISSING.
329
3303.92 Wed Jun 29 14:45:41 CEST 2011
331 - ecb.h was missing.
332
3333.91 Wed Jun 29 13:24:42 CEST 2011
334 - (libeio) work around a Linux (and likely FreeBSD and other
335 kernels) bug where sendfile would not transfer all the requested
336 bytes on large transfers, using a heuristic.
337 - buggy sendfile caused aio_move/copy to sometimes fail for big
338 files (fortunately it checks that the whole file has been
339 transferred...)
340 - use libecb for higher performance and higher portability.
341 - (libeio) disable sendfile on darwin, it's too broken.
342 - disable fork tests on !linux, as only linux supports mixing
343 pthread and fork in perl.
344 - document the fact that fork doesn't work anymore when using
345 this module, on anything !GNU/Linux.
346 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
347 run on a 0.1MHz cpu. Or so.
348
3493.9 Fri May 27 02:43:47 CEST 2011
350 - (libeio) fix memory corruption in aio_readdirx for the flags
351 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
352 - add lots of newer POSIX and GNU/Linux-specific open
353 flags.
354

356 - use nonstandard but maybe-working-on-bsd fork technique.
357 - support a max_idle value of 0.
358 - support setting of idle timeout value (IO::AIO::idle_timeout).
359
3603.72 Fri Feb 11 04:25:38 CET 2011
361 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
362 - aio_mknod always used a dev_t value of 0.
363 - new treescan option: --grep.
364 - add more S_IF macros, and major/minor/makedev "macros".
365
3663.71 Thu Dec 30 08:18:46 CET 2010
367 - the numerical result value passed to callbacks did not stringify
368 correctly, due to internal reuse and failure to reset the sv flags.
369 - actually test for posix_[mf]advise, as at least uClibc defines
370 _POSIX_ADVISORY_INFO without actually having any of the required
371 funcitonality. ugh.
372
3733.7 Mon Nov 1 23:00:34 CET 2010
374 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
375 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
376 - document the sad state of affairs w.r.t. pthread on many bsds.
377 - do not enable mmap on systems without _POSIX_MAPPED_FILES
378 (openbsd 4.8).
379 - do not leak memory in IO::AIO::mmap when the scalar already
380 had string-data.
381 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
382 them.
383 - cache the result IV, for a minor speedup in the common case.
384 - croak when an mmapped-scalar changes location, to detect
385 user-errors better.
386 - fix aio_readlink prototype.
387
3883.65 Wed Mar 31 02:45:05 CEST 2010
389 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
390 cut off long pathnames in aio_readlink (based on patch by
391 Rasmus Andersson).
392 - a double fork partially killed the event pipe (great testcase
393 by dormando). affects IO::AIO, BDB and Async::Interrupt.
394 - suck steve's dick and rename our symbols to avoid colliding
395 with nonstandard identifier spam on the broken os x pseudo-os.
396 affects IO::AIO and BDB.
397
3983.6 Mon Jan 11 00:43:39 CET 2010
399 - (libeio) more fixes for the freebsd/apple sendfile - broken by
400 manpage standards, but apparently correct accoridng to actual
401 kernel sources.
402 - add IO::AIO::mmap/munmap support.
403 - add IO::AIO::m(un)lockall support.
404 - clean up manpage.
405
4063.5 Thu Jan 7 21:25:04 CET 2010
407 - (liebio) fix freebsd sendfile (Vanilla Hsu).
408 - (libeio) also fix darwin sendfile that suffered from a similar bug.
409 - add aio_statvfs as interface to statvfs/fstatvfs.
410 - work around buggy symlink() on cygwin in the testsuite.
411 - wtf. freebsd-8.0 actually passes the testsuite! I knew
412 they could implement fork and semaphores one day! cheers!
413
4143.4 Sat Jan 2 15:13:04 CET 2010
415 - (libeio) max_poll_time was not properly converted to ticks.
416 - clarify cancel_subs description.
417 - IO::AIO::sendfile did not actually return the return value
418 from the sendfile call.
419 - implement aio_msync, aio_mtouch.
420 - (libeio) tentatively support darwin in sendfile.
421
4223.31 Thu Nov 12 02:14:29 CET 2009
423 - fix result status documentation of aio_copy, aio_move.
424 - speed up object creation considerably by avoiding
425 hash lookups.
426
4273.3 Wed Aug 5 13:52:58 CEST 2009
428 - use common::sense.
429 - use common schmorp.h header.
430 - allow integers (file descriptors) in addition to file handles.
431 - take advantage of linux' eventfd (but it seems slower on smp?).
432 - use poll not select on posix platforms.
433
4343.261 Wed Jul 1 10:11:51 CEST 2009
435 - more 0S X workarounds (patch by Tokuhiro Matsuno).
436
4373.26 Tue Jun 30 09:33:26 CEST 2009
438 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
439 try to work around this horribly broken OS in a somewhat hackish
440 way. might help other os's too.
441
4423.25 Sat Jun 27 05:18:26 CEST 2009
443 - added IO::AIO::fadvise and IO::AIO::sendfile.
444 - (libeio) replaced quicksort+insertion sort by a tuned radix
445 sort + insertion sort, resulting in comparable runtime (usually
446 faster) to the old version, but without any ill side effects on
447 degenerated (for quicksort) data.
448 - (libeio) correctly sort dirs by inodes if we have perfect type
449 knowledge and DIRS_FIRST is used.
450 - (libeio) internally the wrong DT_* constants were used, but no
451 known system has differing EIO_DT_*/DT_* values, so not an issue.
452 - removed a (harmless) assert that was left over on the code
453 but should not have been.
454 - use more correct types (change IO length from IV to VAL64,
455 which makes a difference on systems without 64 bit perls).
456
4573.23 Sat Jun 13 16:57:58 CEST 2009
458 - fix off-by-one bug in aio_readdir that was introduced in the
459 rushed 3.22 release.
460
4613.22 Sat Jun 13 15:32:40 CEST 2009
462 - speed up readdirx sort algorithm slightly.
463 - bin/treescan was missing from distro tarball.
464
4653.21 Fri Jun 12 18:45:53 CEST 2009
466 - new options --dirs and --files for treescan.
467 - install bin/treescan by default.
468 - (libeio) aio_readdir can now be cancelled while executing.
469 - fix a printf format string for 64 bit systems (could lead
470 to problems on big endian 64 bit systems).
471 - do not use qsort() but our own algorithm: glibc initialises
472 the whole locale and I/O subsystem inside qsort, causing
473 a stack overflow on 32 bit machines. The new sort uses much less
474 stack and is more than twice as fast in typical situations.
475
4763.2 Sun Jun 7 20:30:05 CEST 2009
477 - (libeio) pwrite emulation was even more flawed than intended and did
478 not restore the file offset.
479 - add aio_readdirx, which can return inode and filetype and sort
480 the names in various ways.
481 - unfortunately, utime, chmod, chown on an open file that has just
482 been written can easily block, which caused aio_copy to block the
483 process. no more!
484 - no longer rely on dst path in aio_copy when futime is available.
485
4863.19 Tue Apr 21 22:05:21 CEST 2009
487 - more perl 5.10 workarounds for aio_read and write.
488 - aio_write no longer modifies the sv (if possible).
489 - aio_read now works correctly with magic values.
490
4913.18 Sun Apr 19 21:17:32 CEST 2009
492 - better diagnostics when some aio_* functions get passed an illegal fh.
493 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
494
4953.17 Thu Nov 20 08:45:36 CET 2008
496 - (libeio) added aio_sync_file_range (untested).
497 - add aio_busy to @IO::AIO::AIO_REQ.
498
4993.16 Wed Oct 22 18:28:01 CEST 2008
500 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
501 part to improve portability to perl 5.8 (reported by szymon).
502
5033.15 Mon Oct 13 00:39:55 CEST 2008
504 - automatic removal of feeders was broken.
505 - (libeio) use a more robust method to detect whether a feeder
506 has added something to the group or not.
507
5083.1 Thu Oct 2 13:34:40 CEST 2008
509 - pre-deref the passed callback object, for increased speed
510 and decreased memory usage.
511 - call on_next_submit callback even for aio_group - impact unknown,
512 but seems more correct.
513 - $req->cb now returns the original callback.
514 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
515 requiring a thread switch.
516 - (libeio) status code of aio_futime and aio_utime was always passed 0.
517 - do some other ยต-optimisations.
518
5193.07 Sat Aug 2 16:06:13 CEST 2008
520 - do not include LIBS in autoconf tests.
521
5223.06 Tue Jul 15 12:41:32 CEST 2008
523 - move preadwritelock definition before it's first reference,
524 to make it compile again on broken platforms (they still exist)
525 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
526
5273.05 Thu Jun 19 23:23:52 CEST 2008
528 - work around perl overriding readdir etc. with thread-unsafe
529 (sic!) versions.
530
5313.04 Wed Jun 18 01:35:38 CEST 2008
532 - (libeio) fix eio_mknod, which confused it's arguments.
533 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
534 is stupid.
535 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
536 - (libeio) fix a bug that could potentially cause IO::AIO
537 not to get initialised properly.
538
5393.03 Thu May 29 05:33:30 CEST 2008
540 - (libeio) correctly call pthread_attr_destroy ().
541 - (libeio) work around broken bsd headers once more.
542 - reduce shared library size again by not including wrappers.
543 - max_outstanding could cause poll to enter a busy-waiting loop.
544 - document the new IO::AIO::poll_cb result value.
545
5463.02 Mon May 12 02:32:02 CEST 2008
547 - fix a memory leak on aio_readlink.
548 - bring back working fchmod.
549 - nop and busy now set result to 0.
550 - set errno to ENOMEM when allocation fails.
551
5523.01 Sun May 11 03:07:03 CEST 2008
553 - (libeio) make it compile on systems without readahead or readdir_r.
554 - (libeio) improve configure check for readahead availability.
555 - do not try to link against -lrt.
556 - use a separate configure script for IO::AIO (not the libeio one).
557
5583.0 Sun May 11 00:57:14 CEST 2008
559 - added bin/treescan to the distribution.
560 - switched to using libeio.
561 - LOTS OF INCOMPATIBLE CHANGES:
562 - remove signal functionality, it is not worth the effort.
563 - max_outstanding no longer returns the previous number of requests.
564 - poll_cb no longer returns number of requests.
565
5662.62 Sat Apr 26 13:59:33 CEST 2008
567 - port to solaris perls configured for old posix
568 (analysed by Jost Krieger).
569 - keep a reference to the perl filehandle object in aio_close,
570 so it doesn't get closed prematurely, leading to ugly races.
571
5722.61 Wed Apr 16 18:45:02 CEST 2008
573 - fix treescan output duplication and improve output ordering.
574 also display files given on the commandline.
575 - use a different algorithm for aio_close that is faster
576 and probably has even lower chances of blocking.
577 - do our own stack memory management for threads - linux
578 allocates outrageous amounts of VM (not so bad unless you
579 use mlockall...), which severely limits the number of threads
580 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
581 and 4096 * sizeof (long) (usually this is 16..64k).
582
5832.6 Sun Mar 30 08:28:11 CEST 2008
584 - added aio_sync.
585 - added aio_pathsync.
586 - fix prototypes of (void) functions.
587
5882.51 Sat Oct 6 16:04:54 CEST 2007
589 - perlio isn't generally threadsafe, so aio_close could not work reliably.
590 aio_close now tries a safe hack that might not be that asynchronous
591 (see the manpage for details).
592 - discard callback return values as to not grow the stack endlessly
593 when poll_cb handles many requests without returning.
594 - minor code cleanups.
595
5962.5 Thu Oct 4 14:49:08 CEST 2007
597 - replaced _fd2fh with faster xs code.
598 - aio_close will now try to do "the right thing" and thus might
599 work sensibly for the very first time.
600
6012.41 Mon Sep 24 21:28:21 CEST 2007
602 - after fork, invest some work to make sure that the poll_fileno
603 stays stable (by dup2'ing the new fd over the old one), to make
604 it easier for programs/libs that don't control their forking
605 behaviour and cannot recreate their watchers.
606
6072.4 Sun Aug 5 18:44:22 CEST 2007
608 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
609 successfully demonstrated that you can block on futimes...).
610 - allow undef as fileoffset for aio_read/write and use read/write(2)
611 internally (useful for sockets or O_APPEND handles).
612 - allow undef for length in aio_write.
613 - negative dataoffsets work as expected now in aio_read/aio_write.
614 - use NV instead of UV for 32 bit perls and file offsets, as NVs
615 have a larger range then.
616 - shared code between BDB and IO::AIO.
617 - aio_busy was completely broken. now fixed.
618 - readahead emulation now returns something.
619 - correctly set errno to ENOSYS on unimplemented functions
620 (should never happen, though).
621 - large changes to make it partially compile and run on win32,
622 but win32 lacks too much functionality, and perl overrides way
623 too many functions with crashing versions.
624
6252.33 Tue Jan 23 23:55:41 CET 2007
626 - fix install path (Andreas J. Koenig).
627
6282.32 Mon Jan 22 16:56:23 CET 2007
629 - added aio_rmtree.
630 - wow, aio_mkdir was missing.
631 - aio_load did return undef on error, not -1.
632 - use prefixexp not prefix in autoconf.pm
633 (suggested by ... rt.cpan.org unreachable).
634 - avoid installing autoconf.pm.
635
6362.31 Sat Jan 6 03:46:02 CET 2007
637 - added aio_load.
638
6392.3 Sat Dec 23 05:48:07 CET 2006
640 - fix off-by-one bug in aio_read, causing memory corruption
641 or crashes.
642
6432.21 Fri Dec 22 05:03:38 CET 2006
644 - minor doc updates.
645 - minor cleanups.
646 - IO::AIO::poll returns request count.
647 - undocumented and unfinished async-signal-reporting.
648
6492.2 Tue Oct 31 00:31:00 CET 2006
650 - minor doc updates.
651 - added aio_readlink.
652 - properly zero-terminate aio_read buffer.
653 - fix aio_read/write with nonzero dataoffset.
654 - reduced size of aio request structure.
655 - better diagnostics when pathnames etc. are not byte-encoded;
656 do not leak request in that case, either.
6 657
72.1 Sun Oct 29 02:01:57 CET 2006 6582.1 Sun Oct 29 02:01:57 CET 2006
8 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by 659 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
9 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. 660 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
10 - fix a bug in aio_move where it would fail everytime 661 - fix a bug in aio_move where it would fail everytime
