48
49 - test for umount seperately, as it is more portable.
50
514.79 Sun 25 Sep 2022 18:25:53 CEST
52 - the autoconf result of the mount check was not used, so it failed to
53 compile on most systems (reported by crackoff@tutanota.com).
54 - work around fedora not having a working C compiler setup by design
55 (reported by Paul Howarth).
56
574.78 Tue 06 Sep 2022 12:54:43 CEST
58 - add IO::AIO::mount and IO::AIO::umount.
59 - add a bunch of symbols from sys/mount.h.
60
614.77 Mon 05 Sep 2022 02:03:38 CEST
62 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
63 - add fexecve.
64 - add lots of missing functions to @EXPORT_OK.
65
664.76 Tue Jul 27 20:45:01 CEST 2021
67 - add autoconf test for siginfo_t, which is, of course, not
68 available on windows (reported by Peter Petky).
69 - disable syscalls on solaris, as perl seems to provide an
70 incompatible syscall prototype that clashes with sys/syscall.h.
71 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
72 MAP_UNINITIALIZED.
73
744.75 Wed Dec 30 08:44:55 CET 2020
75 - removed leftover debug output from treescan.
76 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
77 FSCONFIG_*, MOUNT_ATTR_* constants.
78
794.74 Tue Dec 29 16:19:28 CET 2020
80 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
81 - rework bin/treescan to avoid recursion. This fixes two bugs
82 where a deep directory traversal or a lot of command line
83 arguments could cause it to crash.
84 - added (but not documented) open_tree, AT_* and move_mount flags.
85 - support defining syscall numbers in gendef0.
86
874.73 Fri Dec 4 02:08:37 CET 2020
88 - def0.h was not uptodate, running into musl problems
89 (reported by B Fraser).
90 - IO::AIO::splice and IO::AIO::tee didn't properly return
91 64 bit values.
92 - added IO::AIO::accept4.
93 - add various F_SEAL related fcntl constants.
94 - removed experimental marker for fdlimit functions.
95 - fiemap now includes the last segment even if it overflows
96 the end offset, which is arguably the correct behaviour.
97
984.72 Wed Apr 3 04:56:03 CEST 2019
99 - (libeio) if fd 0 is available do not use it for aio_wd, as it
100 collides with IO::AIO::CWD.
101 - added IO::AIO::memfd_create.
102 - correctly include <sys/uio.h> in the vmsplice test.
103 - reduce codesize by ~7% on amd64 by declaring more functions
104 as noinline.
105 - documentation fixes and updates.
106 - experimental and undocumented preliminary support for synchronous statx.
107
1084.71 Sun Mar 10 13:09:26 CET 2019
109 - due to an error in the linux manpages, the configure tests
110 for readahead, sync_file_range, splice etc. failed. This has been fixed.
111
1124.7 Mon Mar 4 11:28:13 CET 2019
113 - majorly speed up scandir for the very special case of a non-POSIX
114 filesystem that nevertheless reports valid dt_type information.
115 The only known filesystem of this type is currently btrfs, which
116 didn't get it's act together to implement POSIX semantics in all
117 these years, and I am tired of waiting.
118 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
119 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
120 were detected by autoconf.
121
1224.6 Sat Aug 25 21:58:36 CEST 2018
123 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
124 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
125 but only st_gen on openbsd because they compiled their perl without support
126 for birthtimes).
127 - fix madvise and munlock to properly support negative offsets.
128 - allocate fd for the aio_close at boot time, to guarantee it working
129 later, rather than calling abort when it fails. also avoids
130 close-on-exec race issues after module load.
131 - #undef utime on win32, maybe this helps some reports of utime hangs.
132 - minor doc improvements.
133 - minor configure cleanups.
134 - use $Config{perllibs} instead of libs for configure. might help people
135 who didn't install all perl dependencies (might break things as well).
136
1374.54 Tue Aug 14 13:54:48 CEST 2018
138 - include sys/mkdev.h or sys/sysmacros.h if available.
139 - further tweaks to configure invocation for systems requiring --rpath.
140 - no longer rely on custom paths on win32 platforms.
141 - try to work around buggy PAGESIZE macro on solaris.
142
1434.53 Tue Aug 14 11:27:50 CEST 2018
144 - add $Config{libs} to LIBS for configure, to work around systems
145 with broken library dependencies (... openbsd).
146
1474.52 Sun Aug 12 08:09:45 CEST 2018
148 - config.h.in was missing in distribution.
149
1504.51 Sun Aug 12 07:24:14 CEST 2018
151 - complete rework of the autoconf framework: IO::AIO now uses its own
152 config.h, separate from libeio, and tries to test the actual perl
153 environment, not the standard system environment.
154 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
155 stat functions.
156 - removed non-portable C++ syntax from eio.c.
157 - try to fix readdir tests on cygwin spuriously failing.
158
1594.5 Wed Aug 1 00:23:55 CEST 2018
160 - aio_mtouch touch all pages as requested, not just the first page in most cases.
161 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
162 and MREMAP_FIXED.
163 - add O_ACCMODE.
164 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
165
1664.4 Tue Feb 20 07:54:12 CET 2018
167 - new aio_slurp request.
168 - add (experimental) IO::AIO::eventfd and timerfd* function.
169 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
170 - point out that aio_copy overwrites existing files.
171 - removed filesystem magic number table from aio_statvfs docs as
172 statvfs doesn't actually return this info at all (statfs does).
173 - add a bunch of (mostly linux-specific) constants for use in ioctls
174 (see aio_ioctl docs).
175 - treescan now has a proper manpage and useful --help output.
176 - new option --sync in treescan, to sync everything in a subtree.
177 - changed default for aio_msync flags to MSYNC_SYNC.
178 - document offset/length behaviour of mprotect/madvise.
179 - support linux's renameat2 (via aio_rename2).
180 - add aio_rename2, an aio_rename with flags.
181 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
182 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
183 - (libeio) use posix_close if available.
184 - (libeio) internal close() calls no longer disturb errno.
185 - add IO:AIO::FALLOC_FL_UNSHARE.
186 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
187 and better eventfd detection.
188
1894.34 Sun May 1 19:18:24 CEST 2016
190 - def0.h was not properly generated during previous release, causing
191 compile errors on various platforms.
192 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
193 - removed duplicate definition of MAP_HUGETLB, that was found due to
194 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
195 - added (untested!) aio_fcntl, aio_ioctl requests.
196 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
197 as manpages-dev originally claimed.
198
1994.33 Mon Jan 18 12:50:10 CET 2016
200 - add IO::AIO::pipe2 function.
201 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
202 constants.
203 - added support for O_TMPFILE and O_PATH constants.
204 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
205 consdtants, whether they can be sensibly used or not.
206 - use NO_INIT where applicable.
207 - update libecb.
208 - added stability canary support.
209 - updated linux super magic table to 4.3.3.
210
2114.32 Wed Feb 11 20:32:11 CET 2015
212 - replace off_t by STRLEN where appropriate, should not result in
213 user-visible changes.
214 - update ecb.h for C11 compatibility.
215
2164.31 Tue Jun 3 03:29:27 CEST 2014
217 - work around more 5.20 bugs. backwards compatibility my ass.
218
2194.3 Fri Apr 11 06:22:38 CEST 2014
220 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
221 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
222 in 5.18. What's so attractive about giving a shit about backwards
223 compatibility - I will never understand.
224
2254.2 Sat Jan 25 01:13:14 CET 2014
226 - aio_group could corrupt memory because it didn't restore
227 the stack after req_submit.
228 - be more careful on (e.g. permission) errors in bin/treescan.
229 - work around changes in ExtUtils::MakeMaker.
230 - (libeio) implement aio_realpath for win32.
231 - (xthread) work around compile time bugs in ptw32.
232 - added IO::AIO::pipesize.
233 - (libecb) insignificant update.
234
2354.19 Sun Jan 6 12:47:26 CET 2013
236 - avoid endless loop in fiemap with some XFS files.
237 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
238 and call rename/rmdir instead of renameat/unlinkat.
239
2404.18 Thu Oct 11 07:01:26 CEST 2012
241 - fix unintended xthread_create by intentionalising it :)
242
2434.17 Thu Oct 11 05:19:47 CEST 2012
244 - rename aio_fallocate to aio_allocate, to match documentation.
245 - add list of linux fsid values to aio_statvfs docs.
246 - work around a bug in btrfs' FIEMAP ioctl implementation.
247 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
248 as per unix spec.
249
2504.16 Tue Aug 14 05:39:03 CEST 2012
251 - aio_statvfs was wromgly marked for wd emulation, causing
252 it to malfunction for paths.
253 - fix a crash in aio_fiemap, when used on ranges without any
254 extents.
255 - work around linux kernel bug (at least in 3.2): kernel might
256 trash fiemap input arguments.
257 - work around linux kernel bug (at least in 3.2): kernel does not
258 set FIEMAP_EXTENT_LAST on last segment.
259 - work around linux kernel bug (at least in 3.2): kernel silently
260 truncates segment count if a file.
261 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
262 to quick overview.
263 - splice can corrupt data.
264 - (libeio) remove pread/pwrite emulation.
265 - do not grow mmaped scalars in aio_read.
266 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
267 - provide pread/pwrite for win32, making it link again on native win32.
268
2694.15 Tue Apr 10 06:59:00 CEST 2012
270 - always include linux/types.h for fiemap, for compatibility to
271 ancient systems (Paul Howarth).
272 - experimental support for IO::AIO::splice and ::tee (no aio_...).
273 - provide SEEK_HOLE and SEEK_DATA, if available.
274 - work around (again!) an immensely stupid bug in RHEL, defining
275 autoconf macros in linux system headers (analysed by Paul Howarth).
276
2774.14 Sat Apr 7 02:45:18 CEST 2012
278 - fix stat structure usage on windows, which caused bogus stat results.
279 - (libeio) make readahead emulation behave more like actual readahead by never failing.
280 - new request aio_seek.
281 - new request aio_fiemap.
282 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
283
2844.12 Fri Dec 30 08:51:25 CET 2011
285 - realpath would return a random value if the name was too long,
286 instead of -1.
287 - port to c89.
288
2894.11 Mon Oct 10 00:24:11 CEST 2011
290 - libeio didn't compile on !linux (Paul Howarth).
291
2924.1 Sun Oct 9 10:24:11 CEST 2011
293 - IO::AIO did access uninitialised memory on unsuccessful stats.
294 - (libeio) added syncfs syscall wrapper.
295 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
296 - (libeio) support multiple indepenent working directories.
297 - applied speling corrections by Nicholas Bamber.
298 - tune treescan #threads and #outstanding requests a bit.
299 - reduce the number of file descriptors in use at any one time
300 in treescan, to avoid running out of them (and using too much ram).
301 - take advantage of working directoriy abstractions
302 in aio_scandir and treescan.
303 - reduce compiled size by ~10% by not inlining some key functionality.
304 - added --progress switch to treescan.
305
3064.0 Mon Jul 18 05:01:10 CEST 2011
307 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
308 see FORK BEHAVIOUR in manpage for details.
309 - passes testsuite on win32 now and may actually work
310 (activestate 5.10.1 / MSVC6, YMMV).
311 - (libeio) fix a deadlock where a wakeup signal could be missed when
312 a timeout occured at the same time.
313 - (libeio) added realpath.
314 - (libeio) added fallocate.
315 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
316 - (libeio) do not acquire any locks when forking.
317 - (libeio) use fewer time() syscalls when waiting for new requests.
318
3193.93 Wed Jun 29 23:44:18 CEST 2011
320 - ECB.H WAS MISSING.
321
3223.92 Wed Jun 29 14:45:41 CEST 2011
323 - ecb.h was missing.
324
3253.91 Wed Jun 29 13:24:42 CEST 2011
326 - (libeio) work around a Linux (and likely FreeBSD and other
327 kernels) bug where sendfile would not transfer all the requested
328 bytes on large transfers, using a heuristic.
329 - buggy sendfile caused aio_move/copy to sometimes fail for big
330 files (fortunately it checks that the whole file has been
331 transferred...)
332 - use libecb for higher performance and higher portability.
333 - (libeio) disable sendfile on darwin, it's too broken.
334 - disable fork tests on !linux, as only linux supports mixing
335 pthread and fork in perl.
336 - document the fact that fork doesn't work anymore when using
337 this module, on anything !GNU/Linux.
338 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
339 run on a 0.1MHz cpu. Or so.
340
3413.9 Fri May 27 02:43:47 CEST 2011
342 - (libeio) fix memory corruption in aio_readdirx for the flags
343 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
344 - add lots of newer POSIX and GNU/Linux-specific open
345 flags.
346

348 - use nonstandard but maybe-working-on-bsd fork technique.
349 - support a max_idle value of 0.
350 - support setting of idle timeout value (IO::AIO::idle_timeout).
351
3523.72 Fri Feb 11 04:25:38 CET 2011
353 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
354 - aio_mknod always used a dev_t value of 0.
355 - new treescan option: --grep.
356 - add more S_IF macros, and major/minor/makedev "macros".
357
3583.71 Thu Dec 30 08:18:46 CET 2010
359 - the numerical result value passed to callbacks did not stringify
360 correctly, due to internal reuse and failure to reset the sv flags.
361 - actually test for posix_[mf]advise, as at least uClibc defines
362 _POSIX_ADVISORY_INFO without actually having any of the required
363 funcitonality. ugh.
364
3653.7 Mon Nov 1 23:00:34 CET 2010
366 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
367 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
368 - document the sad state of affairs w.r.t. pthread on many bsds.
369 - do not enable mmap on systems without _POSIX_MAPPED_FILES
370 (openbsd 4.8).
371 - do not leak memory in IO::AIO::mmap when the scalar already
372 had string-data.
373 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
374 them.
375 - cache the result IV, for a minor speedup in the common case.
376 - croak when an mmapped-scalar changes location, to detect
377 user-errors better.
378 - fix aio_readlink prototype.
379
3803.65 Wed Mar 31 02:45:05 CEST 2010
381 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
382 cut off long pathnames in aio_readlink (based on patch by
383 Rasmus Andersson).
384 - a double fork partially killed the event pipe (great testcase
385 by dormando). affects IO::AIO, BDB and Async::Interrupt.
386 - suck steve's dick and rename our symbols to avoid colliding
387 with nonstandard identifier spam on the broken os x pseudo-os.
388 affects IO::AIO and BDB.
389
3903.6 Mon Jan 11 00:43:39 CET 2010
391 - (libeio) more fixes for the freebsd/apple sendfile - broken by
392 manpage standards, but apparently correct accoridng to actual
393 kernel sources.
394 - add IO::AIO::mmap/munmap support.
395 - add IO::AIO::m(un)lockall support.
396 - clean up manpage.
397
3983.5 Thu Jan 7 21:25:04 CET 2010
399 - (liebio) fix freebsd sendfile (Vanilla Hsu).
400 - (libeio) also fix darwin sendfile that suffered from a similar bug.
401 - add aio_statvfs as interface to statvfs/fstatvfs.
402 - work around buggy symlink() on cygwin in the testsuite.
403 - wtf. freebsd-8.0 actually passes the testsuite! I knew
404 they could implement fork and semaphores one day! cheers!
405
4063.4 Sat Jan 2 15:13:04 CET 2010
407 - (libeio) max_poll_time was not properly converted to ticks.
408 - clarify cancel_subs description.
409 - IO::AIO::sendfile did not actually return the return value
410 from the sendfile call.
411 - implement aio_msync, aio_mtouch.
412 - (libeio) tentatively support darwin in sendfile.
413
4143.31 Thu Nov 12 02:14:29 CET 2009
415 - fix result status documentation of aio_copy, aio_move.
416 - speed up object creation considerably by avoiding
417 hash lookups.
418
4193.3 Wed Aug 5 13:52:58 CEST 2009
420 - use common::sense.
421 - use common schmorp.h header.
422 - allow integers (file descriptors) in addition to file handles.
423 - take advantage of linux' eventfd (but it seems slower on smp?).
424 - use poll not select on posix platforms.
425
4263.261 Wed Jul 1 10:11:51 CEST 2009
427 - more 0S X workarounds (patch by Tokuhiro Matsuno).
428
4293.26 Tue Jun 30 09:33:26 CEST 2009
430 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
431 try to work around this horribly broken OS in a somewhat hackish
432 way. might help other os's too.
433
4343.25 Sat Jun 27 05:18:26 CEST 2009
435 - added IO::AIO::fadvise and IO::AIO::sendfile.
436 - (libeio) replaced quicksort+insertion sort by a tuned radix
437 sort + insertion sort, resulting in comparable runtime (usually
438 faster) to the old version, but without any ill side effects on
439 degenerated (for quicksort) data.
440 - (libeio) correctly sort dirs by inodes if we have perfect type
441 knowledge and DIRS_FIRST is used.
442 - (libeio) internally the wrong DT_* constants were used, but no
443 known system has differing EIO_DT_*/DT_* values, so not an issue.
444 - removed a (harmless) assert that was left over on the code
445 but should not have been.
446 - use more correct types (change IO length from IV to VAL64,
447 which makes a difference on systems without 64 bit perls).
448
4493.23 Sat Jun 13 16:57:58 CEST 2009
450 - fix off-by-one bug in aio_readdir that was introduced in the
451 rushed 3.22 release.
452
4533.22 Sat Jun 13 15:32:40 CEST 2009
454 - speed up readdirx sort algorithm slightly.
455 - bin/treescan was missing from distro tarball.
456
4573.21 Fri Jun 12 18:45:53 CEST 2009
458 - new options --dirs and --files for treescan.
459 - install bin/treescan by default.
460 - (libeio) aio_readdir can now be cancelled while executing.
461 - fix a printf format string for 64 bit systems (could lead
462 to problems on big endian 64 bit systems).
463 - do not use qsort() but our own algorithm: glibc initialises
464 the whole locale and I/O subsystem inside qsort, causing
465 a stack overflow on 32 bit machines. The new sort uses much less
466 stack and is more than twice as fast in typical situations.
467
4683.2 Sun Jun 7 20:30:05 CEST 2009
469 - (libeio) pwrite emulation was even more flawed than intended and did
470 not restore the file offset.
471 - add aio_readdirx, which can return inode and filetype and sort
472 the names in various ways.
473 - unfortunately, utime, chmod, chown on an open file that has just
474 been written can easily block, which caused aio_copy to block the
475 process. no more!
476 - no longer rely on dst path in aio_copy when futime is available.
477
4783.19 Tue Apr 21 22:05:21 CEST 2009
479 - more perl 5.10 workarounds for aio_read and write.
480 - aio_write no longer modifies the sv (if possible).
481 - aio_read now works correctly with magic values.
482
4833.18 Sun Apr 19 21:17:32 CEST 2009
484 - better diagnostics when some aio_* functions get passed an illegal fh.
485 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
486
4873.17 Thu Nov 20 08:45:36 CET 2008
488 - (libeio) added aio_sync_file_range (untested).
489 - add aio_busy to @IO::AIO::AIO_REQ.
490
4913.16 Wed Oct 22 18:28:01 CEST 2008
492 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
493 part to improve portability to perl 5.8 (reported by szymon).
494
4953.15 Mon Oct 13 00:39:55 CEST 2008
496 - automatic removal of feeders was broken.
497 - (libeio) use a more robust method to detect whether a feeder
498 has added something to the group or not.
499
5003.1 Thu Oct 2 13:34:40 CEST 2008
501 - pre-deref the passed callback object, for increased speed
502 and decreased memory usage.
503 - call on_next_submit callback even for aio_group - impact unknown,
504 but seems more correct.
505 - $req->cb now returns the original callback.
506 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
507 requiring a thread switch.
508 - (libeio) status code of aio_futime and aio_utime was always passed 0.
509 - do some other ยต-optimisations.
510
5113.07 Sat Aug 2 16:06:13 CEST 2008
512 - do not include LIBS in autoconf tests.
513
5143.06 Tue Jul 15 12:41:32 CEST 2008
515 - move preadwritelock definition before it's first reference,
516 to make it compile again on broken platforms (they still exist)
517 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
518
5193.05 Thu Jun 19 23:23:52 CEST 2008
520 - work around perl overriding readdir etc. with thread-unsafe
521 (sic!) versions.
522
5233.04 Wed Jun 18 01:35:38 CEST 2008
524 - (libeio) fix eio_mknod, which confused it's arguments.
525 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
526 is stupid.
527 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
528 - (libeio) fix a bug that could potentially cause IO::AIO
529 not to get initialised properly.
530
5313.03 Thu May 29 05:33:30 CEST 2008
532 - (libeio) correctly call pthread_attr_destroy ().
533 - (libeio) work around broken bsd headers once more.
534 - reduce shared library size again by not including wrappers.
535 - max_outstanding could cause poll to enter a busy-waiting loop.
536 - document the new IO::AIO::poll_cb result value.
537
5383.02 Mon May 12 02:32:02 CEST 2008
539 - fix a memory leak on aio_readlink.
540 - bring back working fchmod.
541 - nop and busy now set result to 0.
542 - set errno to ENOMEM when allocation fails.
543
5443.01 Sun May 11 03:07:03 CEST 2008
545 - (libeio) make it compile on systems without readahead or readdir_r.
546 - (libeio) improve configure check for readahead availability.
547 - do not try to link against -lrt.
548 - use a separate configure script for IO::AIO (not the libeio one).
549
5503.0 Sun May 11 00:57:14 CEST 2008
551 - added bin/treescan to the distribution.
552 - switched to using libeio.
553 - LOTS OF INCOMPATIBLE CHANGES:
554 - remove signal functionality, it is not worth the effort.
555 - max_outstanding no longer returns the previous number of requests.
556 - poll_cb no longer returns number of requests.
557
5582.62 Sat Apr 26 13:59:33 CEST 2008
559 - port to solaris perls configured for old posix
560 (analysed by Jost Krieger).
561 - keep a reference to the perl filehandle object in aio_close,
562 so it doesn't get closed prematurely, leading to ugly races.
563
5642.61 Wed Apr 16 18:45:02 CEST 2008
565 - fix treescan output duplication and improve output ordering.
566 also display files given on the commandline.
567 - use a different algorithm for aio_close that is faster
568 and probably has even lower chances of blocking.
569 - do our own stack memory management for threads - linux
570 allocates outrageous amounts of VM (not so bad unless you
571 use mlockall...), which severely limits the number of threads
572 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
573 and 4096 * sizeof (long) (usually this is 16..64k).
574
5752.6 Sun Mar 30 08:28:11 CEST 2008
576 - added aio_sync.
577 - added aio_pathsync.
578 - fix prototypes of (void) functions.
579
5802.51 Sat Oct 6 16:04:54 CEST 2007
581 - perlio isn't generally threadsafe, so aio_close could not work reliably.
582 aio_close now tries a safe hack that might not be that asynchronous
583 (see the manpage for details).
584 - discard callback return values as to not grow the stack endlessly
585 when poll_cb handles many requests without returning.
586 - minor code cleanups.
587
5882.5 Thu Oct 4 14:49:08 CEST 2007
589 - replaced _fd2fh with faster xs code.
590 - aio_close will now try to do "the right thing" and thus might
591 work sensibly for the very first time.
592
5932.41 Mon Sep 24 21:28:21 CEST 2007
594 - after fork, invest some work to make sure that the poll_fileno
595 stays stable (by dup2'ing the new fd over the old one), to make
596 it easier for programs/libs that don't control their forking
597 behaviour and cannot recreate their watchers.
598
5992.4 Sun Aug 5 18:44:22 CEST 2007
600 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
601 successfully demonstrated that you can block on futimes...).
602 - allow undef as fileoffset for aio_read/write and use read/write(2)
603 internally (useful for sockets or O_APPEND handles).
604 - allow undef for length in aio_write.
605 - negative dataoffsets work as expected now in aio_read/aio_write.
606 - use NV instead of UV for 32 bit perls and file offsets, as NVs
607 have a larger range then.
608 - shared code between BDB and IO::AIO.
609 - aio_busy was completely broken. now fixed.
610 - readahead emulation now returns something.
611 - correctly set errno to ENOSYS on unimplemented functions
612 (should never happen, though).
613 - large changes to make it partially compile and run on win32,
614 but win32 lacks too much functionality, and perl overrides way
615 too many functions with crashing versions.
616
6172.33 Tue Jan 23 23:55:41 CET 2007
618 - fix install path (Andreas J. Koenig).
619
6202.32 Mon Jan 22 16:56:23 CET 2007
621 - added aio_rmtree.
622 - wow, aio_mkdir was missing.
623 - aio_load did return undef on error, not -1.
624 - use prefixexp not prefix in autoconf.pm
625 (suggested by ... rt.cpan.org unreachable).
626 - avoid installing autoconf.pm.
627
6282.31 Sat Jan 6 03:46:02 CET 2007
629 - added aio_load.
630
6312.3 Sat Dec 23 05:48:07 CET 2006
632 - fix off-by-one bug in aio_read, causing memory corruption
633 or crashes.
634
6352.21 Fri Dec 22 05:03:38 CET 2006
636 - minor doc updates.
8 - minor cleanups. 637 - minor cleanups.
9 - IO::AIO::poll returns request count. 638 - IO::AIO::poll returns request count.
639 - undocumented and unfinished async-signal-reporting.
10 640
112.2 Tue Oct 31 00:31:00 CET 2006 6412.2 Tue Oct 31 00:31:00 CET 2006
12 - minor doc updates. 642 - minor doc updates.
13 - added aio_readlink. 643 - added aio_readlink.
14 - properly zero-terminate aio_read buffer. 644 - properly zero-terminate aio_read buffer.
