514.76 Tue Jul 27 20:45:01 CEST 2021
52 - add autoconf test for siginfo_t, which is, of course, not
53 available on windows (reported by Peter Petky).
54 - disable syscalls on solaris, as perl seems to provide an
55 incompatible syscall prototype that clashes with sys/syscall.h.
56 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
57 MAP_UNINITIALIZED.
58
594.75 Wed Dec 30 08:44:55 CET 2020
60 - removed leftover debug output from treescan.
61 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
62 FSCONFIG_*, MOUNT_ATTR_* constants.
63
644.74 Tue Dec 29 16:19:28 CET 2020
65 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
66 - rework bin/treescan to avoid recursion. This fixes two bugs
67 where a deep directory traversal or a lot of command line
68 arguments could cause it to crash.
69 - added (but not documented) open_tree, AT_* and move_mount flags.
70 - support defining syscall numbers in gendef0.
71
724.73 Fri Dec 4 02:08:37 CET 2020
73 - def0.h was not uptodate, running into musl problems
74 (reported by B Fraser).
75 - IO::AIO::splice and IO::AIO::tee didn't properly return
76 64 bit values.
77 - added IO::AIO::accept4.
78 - add various F_SEAL related fcntl constants.
79 - removed experimental marker for fdlimit functions.
80 - fiemap now includes the last segment even if it overflows
81 the end offset, which is arguably the correct behaviour.
82
834.72 Wed Apr 3 04:56:03 CEST 2019
84 - (libeio) if fd 0 is available do not use it for aio_wd, as it
85 collides with IO::AIO::CWD.
86 - added IO::AIO::memfd_create.
87 - correctly include <sys/uio.h> in the vmsplice test.
88 - reduce codesize by ~7% on amd64 by declaring more functions
89 as noinline.
90 - documentation fixes and updates.
91 - experimental and undocumented preliminary support for synchronous statx.
92
934.71 Sun Mar 10 13:09:26 CET 2019
94 - due to an error in the linux manpages, the configure tests
95 for readahead, sync_file_range, splice etc. failed. This has been fixed.
96
974.7 Mon Mar 4 11:28:13 CET 2019
98 - majorly speed up scandir for the very special case of a non-POSIX
99 filesystem that nevertheless reports valid dt_type information.
100 The only known filesystem of this type is currently btrfs, which
101 didn't get it's act together to implement POSIX semantics in all
102 these years, and I am tired of waiting.
103 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
104 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
105 were detected by autoconf.
106
1074.6 Sat Aug 25 21:58:36 CEST 2018
108 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
109 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
110 but only st_gen on openbsd because they compiled their perl without support
111 for birthtimes).
112 - fix madvise and munlock to properly support negative offsets.
113 - allocate fd for the aio_close at boot time, to guarantee it working
114 later, rather than calling abort when it fails. also avoids
115 close-on-exec race issues after module load.
116 - #undef utime on win32, maybe this helps some reports of utime hangs.
117 - minor doc improvements.
118 - minor configure cleanups.
119 - use $Config{perllibs} instead of libs for configure. might help people
120 who didn't install all perl dependencies (might break things as well).
121
1224.54 Tue Aug 14 13:54:48 CEST 2018
123 - include sys/mkdev.h or sys/sysmacros.h if available.
124 - further tweaks to configure invocation for systems requiring --rpath.
125 - no longer rely on custom paths on win32 platforms.
126 - try to work around buggy PAGESIZE macro on solaris.
127
1284.53 Tue Aug 14 11:27:50 CEST 2018
129 - add $Config{libs} to LIBS for configure, to work around systems
130 with broken library dependencies (... openbsd).
131
1324.52 Sun Aug 12 08:09:45 CEST 2018
133 - config.h.in was missing in distribution.
134
1354.51 Sun Aug 12 07:24:14 CEST 2018
136 - complete rework of the autoconf framework: IO::AIO now uses its own
137 config.h, separate from libeio, and tries to test the actual perl
138 environment, not the standard system environment.
139 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
140 stat functions.
141 - removed non-portable C++ syntax from eio.c.
142 - try to fix readdir tests on cygwin spuriously failing.
143
1444.5 Wed Aug 1 00:23:55 CEST 2018
145 - aio_mtouch touch all pages as requested, not just the first page in most cases.
146 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
147 and MREMAP_FIXED.
148 - add O_ACCMODE.
149 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
150
1514.4 Tue Feb 20 07:54:12 CET 2018
152 - new aio_slurp request.
153 - add (experimental) IO::AIO::eventfd and timerfd* function.
154 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
155 - point out that aio_copy overwrites existing files.
156 - removed filesystem magic number table from aio_statvfs docs as
157 statvfs doesn't actually return this info at all (statfs does).
158 - add a bunch of (mostly linux-specific) constants for use in ioctls
159 (see aio_ioctl docs).
160 - treescan now has a proper manpage and useful --help output.
161 - new option --sync in treescan, to sync everything in a subtree.
162 - changed default for aio_msync flags to MSYNC_SYNC.
163 - document offset/length behaviour of mprotect/madvise.
164 - support linux's renameat2 (via aio_rename2).
165 - add aio_rename2, an aio_rename with flags.
166 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
167 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
168 - (libeio) use posix_close if available.
169 - (libeio) internal close() calls no longer disturb errno.
170 - add IO:AIO::FALLOC_FL_UNSHARE.
171 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
172 and better eventfd detection.
173
1744.34 Sun May 1 19:18:24 CEST 2016
175 - def0.h was not properly generated during previous release, causing
176 compile errors on various platforms.
177 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
178 - removed duplicate definition of MAP_HUGETLB, that was found due to
179 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
180 - added (untested!) aio_fcntl, aio_ioctl requests.
181 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
182 as manpages-dev originally claimed.
183
1844.33 Mon Jan 18 12:50:10 CET 2016
185 - add IO::AIO::pipe2 function.
186 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
187 constants.
188 - added support for O_TMPFILE and O_PATH constants.
189 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
190 consdtants, whether they can be sensibly used or not.
191 - use NO_INIT where applicable.
192 - update libecb.
193 - added stability canary support.
194 - updated linux super magic table to 4.3.3.
195
1964.32 Wed Feb 11 20:32:11 CET 2015
197 - replace off_t by STRLEN where appropriate, should not result in
198 user-visible changes.
199 - update ecb.h for C11 compatibility.
200
2014.31 Tue Jun 3 03:29:27 CEST 2014
202 - work around more 5.20 bugs. backwards compatibility my ass.
203
2044.3 Fri Apr 11 06:22:38 CEST 2014
205 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
206 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
207 in 5.18. What's so attractive about giving a shit about backwards
208 compatibility - I will never understand.
209
2104.2 Sat Jan 25 01:13:14 CET 2014
211 - aio_group could corrupt memory because it didn't restore
212 the stack after req_submit.
213 - be more careful on (e.g. permission) errors in bin/treescan.
214 - work around changes in ExtUtils::MakeMaker.
215 - (libeio) implement aio_realpath for win32.
216 - (xthread) work around compile time bugs in ptw32.
217 - added IO::AIO::pipesize.
218 - (libecb) insignificant update.
219
2204.19 Sun Jan 6 12:47:26 CET 2013
221 - avoid endless loop in fiemap with some XFS files.
222 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
223 and call rename/rmdir instead of renameat/unlinkat.
224
2254.18 Thu Oct 11 07:01:26 CEST 2012
226 - fix unintended xthread_create by intentionalising it :)
227
2284.17 Thu Oct 11 05:19:47 CEST 2012
229 - rename aio_fallocate to aio_allocate, to match documentation.
230 - add list of linux fsid values to aio_statvfs docs.
231 - work around a bug in btrfs' FIEMAP ioctl implementation.
232 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
233 as per unix spec.
234
2354.16 Tue Aug 14 05:39:03 CEST 2012
236 - aio_statvfs was wromgly marked for wd emulation, causing
237 it to malfunction for paths.
238 - fix a crash in aio_fiemap, when used on ranges without any
239 extents.
240 - work around linux kernel bug (at least in 3.2): kernel might
241 trash fiemap input arguments.
242 - work around linux kernel bug (at least in 3.2): kernel does not
243 set FIEMAP_EXTENT_LAST on last segment.
244 - work around linux kernel bug (at least in 3.2): kernel silently
245 truncates segment count if a file.
246 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
247 to quick overview.
248 - splice can corrupt data.
249 - (libeio) remove pread/pwrite emulation.
250 - do not grow mmaped scalars in aio_read.

253
2544.15 Tue Apr 10 06:59:00 CEST 2012
255 - always include linux/types.h for fiemap, for compatibility to
256 ancient systems (Paul Howarth).
257 - experimental support for IO::AIO::splice and ::tee (no aio_...).
258 - provide SEEK_HOLE and SEEK_DATA, if available.
259 - work around (again!) an immensely stupid bug in RHEL, defining
260 autoconf macros in linux system headers (analysed by Paul Howarth).
261
2624.14 Sat Apr 7 02:45:18 CEST 2012
263 - fix stat structure usage on windows, which caused bogus stat results.
264 - (libeio) make readahead emulation behave more like actual readahead by never failing.
265 - new request aio_seek.
266 - new request aio_fiemap.
267 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
268
2694.12 Fri Dec 30 08:51:25 CET 2011
270 - realpath would return a random value if the name was too long,
271 instead of -1.
272 - port to c89.
273
2744.11 Mon Oct 10 00:24:11 CEST 2011
275 - libeio didn't compile on !linux (Paul Howarth).
276
2774.1 Sun Oct 9 10:24:11 CEST 2011
278 - IO::AIO did access uninitialised memory on unsuccessful stats.
279 - (libeio) added syncfs syscall wrapper.

281 - (libeio) support multiple indepenent working directories.
282 - applied speling corrections by Nicholas Bamber.
283 - tune treescan #threads and #outstanding requests a bit.
284 - reduce the number of file descriptors in use at any one time
285 in treescan, to avoid running out of them (and using too much ram).
286 - take advantage of working directoriy abstractions
287 in aio_scandir and treescan.
288 - reduce compiled size by ~10% by not inlining some key functionality.
289 - added --progress switch to treescan.
290
2914.0 Mon Jul 18 05:01:10 CEST 2011
292 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
293 see FORK BEHAVIOUR in manpage for details.
294 - passes testsuite on win32 now and may actually work
295 (activestate 5.10.1 / MSVC6, YMMV).
296 - (libeio) fix a deadlock where a wakeup signal could be missed when
297 a timeout occured at the same time.
298 - (libeio) added realpath.
299 - (libeio) added fallocate.
300 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
301 - (libeio) do not acquire any locks when forking.
302 - (libeio) use fewer time() syscalls when waiting for new requests.
303
3043.93 Wed Jun 29 23:44:18 CEST 2011
305 - ECB.H WAS MISSING.
306
3073.92 Wed Jun 29 14:45:41 CEST 2011
308 - ecb.h was missing.
309
3103.91 Wed Jun 29 13:24:42 CEST 2011
311 - (libeio) work around a Linux (and likely FreeBSD and other
312 kernels) bug where sendfile would not transfer all the requested
313 bytes on large transfers, using a heuristic.
314 - buggy sendfile caused aio_move/copy to sometimes fail for big
315 files (fortunately it checks that the whole file has been
316 transferred...)
317 - use libecb for higher performance and higher portability.
318 - (libeio) disable sendfile on darwin, it's too broken.
319 - disable fork tests on !linux, as only linux supports mixing
320 pthread and fork in perl.
321 - document the fact that fork doesn't work anymore when using
322 this module, on anything !GNU/Linux.
323 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
324 run on a 0.1MHz cpu. Or so.
325
3263.9 Fri May 27 02:43:47 CEST 2011
327 - (libeio) fix memory corruption in aio_readdirx for the flags
328 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
329 - add lots of newer POSIX and GNU/Linux-specific open
330 flags.
331
3323.8 Sun Mar 27 12:25:33 CEST 2011
333 - use nonstandard but maybe-working-on-bsd fork technique.
334 - support a max_idle value of 0.
335 - support setting of idle timeout value (IO::AIO::idle_timeout).
336
3373.72 Fri Feb 11 04:25:38 CET 2011
338 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
339 - aio_mknod always used a dev_t value of 0.
340 - new treescan option: --grep.
341 - add more S_IF macros, and major/minor/makedev "macros".
342
3433.71 Thu Dec 30 08:18:46 CET 2010
344 - the numerical result value passed to callbacks did not stringify
345 correctly, due to internal reuse and failure to reset the sv flags.
346 - actually test for posix_[mf]advise, as at least uClibc defines
347 _POSIX_ADVISORY_INFO without actually having any of the required
348 funcitonality. ugh.
349
3503.7 Mon Nov 1 23:00:34 CET 2010
351 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
352 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
353 - document the sad state of affairs w.r.t. pthread on many bsds.
354 - do not enable mmap on systems without _POSIX_MAPPED_FILES
355 (openbsd 4.8).
356 - do not leak memory in IO::AIO::mmap when the scalar already
357 had string-data.
358 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
359 them.
360 - cache the result IV, for a minor speedup in the common case.
361 - croak when an mmapped-scalar changes location, to detect
362 user-errors better.
363 - fix aio_readlink prototype.
364
3653.65 Wed Mar 31 02:45:05 CEST 2010
366 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
367 cut off long pathnames in aio_readlink (based on patch by
368 Rasmus Andersson).
369 - a double fork partially killed the event pipe (great testcase
370 by dormando). affects IO::AIO, BDB and Async::Interrupt.
371 - suck steve's dick and rename our symbols to avoid colliding
372 with nonstandard identifier spam on the broken os x pseudo-os.
373 affects IO::AIO and BDB.
374
3753.6 Mon Jan 11 00:43:39 CET 2010
376 - (libeio) more fixes for the freebsd/apple sendfile - broken by
377 manpage standards, but apparently correct accoridng to actual
378 kernel sources.
379 - add IO::AIO::mmap/munmap support.
380 - add IO::AIO::m(un)lockall support.
381 - clean up manpage.
382
3833.5 Thu Jan 7 21:25:04 CET 2010
384 - (liebio) fix freebsd sendfile (Vanilla Hsu).
385 - (libeio) also fix darwin sendfile that suffered from a similar bug.
386 - add aio_statvfs as interface to statvfs/fstatvfs.
387 - work around buggy symlink() on cygwin in the testsuite.
388 - wtf. freebsd-8.0 actually passes the testsuite! I knew
389 they could implement fork and semaphores one day! cheers!
390
3913.4 Sat Jan 2 15:13:04 CET 2010
392 - (libeio) max_poll_time was not properly converted to ticks.
393 - clarify cancel_subs description.
394 - IO::AIO::sendfile did not actually return the return value
395 from the sendfile call.
396 - implement aio_msync, aio_mtouch.
397 - (libeio) tentatively support darwin in sendfile.
398
3993.31 Thu Nov 12 02:14:29 CET 2009
400 - fix result status documentation of aio_copy, aio_move.
401 - speed up object creation considerably by avoiding
402 hash lookups.
403
4043.3 Wed Aug 5 13:52:58 CEST 2009
405 - use common::sense.
406 - use common schmorp.h header.
407 - allow integers (file descriptors) in addition to file handles.
408 - take advantage of linux' eventfd (but it seems slower on smp?).
409 - use poll not select on posix platforms.
410
4113.261 Wed Jul 1 10:11:51 CEST 2009
412 - more 0S X workarounds (patch by Tokuhiro Matsuno).
413
4143.26 Tue Jun 30 09:33:26 CEST 2009
415 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
416 try to work around this horribly broken OS in a somewhat hackish
417 way. might help other os's too.
418
4193.25 Sat Jun 27 05:18:26 CEST 2009
420 - added IO::AIO::fadvise and IO::AIO::sendfile.
421 - (libeio) replaced quicksort+insertion sort by a tuned radix
422 sort + insertion sort, resulting in comparable runtime (usually
423 faster) to the old version, but without any ill side effects on
424 degenerated (for quicksort) data.
425 - (libeio) correctly sort dirs by inodes if we have perfect type
426 knowledge and DIRS_FIRST is used.
427 - (libeio) internally the wrong DT_* constants were used, but no
428 known system has differing EIO_DT_*/DT_* values, so not an issue.
429 - removed a (harmless) assert that was left over on the code
430 but should not have been.
431 - use more correct types (change IO length from IV to VAL64,
432 which makes a difference on systems without 64 bit perls).
433
4343.23 Sat Jun 13 16:57:58 CEST 2009
435 - fix off-by-one bug in aio_readdir that was introduced in the
436 rushed 3.22 release.
437
4383.22 Sat Jun 13 15:32:40 CEST 2009
439 - speed up readdirx sort algorithm slightly.
440 - bin/treescan was missing from distro tarball.
441
4423.21 Fri Jun 12 18:45:53 CEST 2009
443 - new options --dirs and --files for treescan.
444 - install bin/treescan by default.
445 - (libeio) aio_readdir can now be cancelled while executing.
446 - fix a printf format string for 64 bit systems (could lead
447 to problems on big endian 64 bit systems).
448 - do not use qsort() but our own algorithm: glibc initialises
449 the whole locale and I/O subsystem inside qsort, causing
450 a stack overflow on 32 bit machines. The new sort uses much less
451 stack and is more than twice as fast in typical situations.
452
4533.2 Sun Jun 7 20:30:05 CEST 2009
454 - (libeio) pwrite emulation was even more flawed than intended and did
455 not restore the file offset.
456 - add aio_readdirx, which can return inode and filetype and sort
457 the names in various ways.
458 - unfortunately, utime, chmod, chown on an open file that has just
459 been written can easily block, which caused aio_copy to block the
460 process. no more!
461 - no longer rely on dst path in aio_copy when futime is available.
462
4633.19 Tue Apr 21 22:05:21 CEST 2009
464 - more perl 5.10 workarounds for aio_read and write.
465 - aio_write no longer modifies the sv (if possible).
466 - aio_read now works correctly with magic values.
467
4683.18 Sun Apr 19 21:17:32 CEST 2009
469 - better diagnostics when some aio_* functions get passed an illegal fh.
470 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
471
4723.17 Thu Nov 20 08:45:36 CET 2008
473 - (libeio) added aio_sync_file_range (untested).
474 - add aio_busy to @IO::AIO::AIO_REQ.
475
4763.16 Wed Oct 22 18:28:01 CEST 2008
477 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
478 part to improve portability to perl 5.8 (reported by szymon).
479
4803.15 Mon Oct 13 00:39:55 CEST 2008
481 - automatic removal of feeders was broken.
482 - (libeio) use a more robust method to detect whether a feeder
483 has added something to the group or not.
484
4853.1 Thu Oct 2 13:34:40 CEST 2008
486 - pre-deref the passed callback object, for increased speed
487 and decreased memory usage.
488 - call on_next_submit callback even for aio_group - impact unknown,
489 but seems more correct.
490 - $req->cb now returns the original callback.
491 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
492 requiring a thread switch.
493 - (libeio) status code of aio_futime and aio_utime was always passed 0.
494 - do some other ยต-optimisations.
495
4963.07 Sat Aug 2 16:06:13 CEST 2008
497 - do not include LIBS in autoconf tests.
498
4993.06 Tue Jul 15 12:41:32 CEST 2008
500 - move preadwritelock definition before it's first reference,
501 to make it compile again on broken platforms (they still exist)
502 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
503
5043.05 Thu Jun 19 23:23:52 CEST 2008
505 - work around perl overriding readdir etc. with thread-unsafe
506 (sic!) versions.
507
5083.04 Wed Jun 18 01:35:38 CEST 2008
509 - (libeio) fix eio_mknod, which confused it's arguments.
510 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
511 is stupid.
512 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
513 - (libeio) fix a bug that could potentially cause IO::AIO
514 not to get initialised properly.
515
5163.03 Thu May 29 05:33:30 CEST 2008
517 - (libeio) correctly call pthread_attr_destroy ().
518 - (libeio) work around broken bsd headers once more.
519 - reduce shared library size again by not including wrappers.
520 - max_outstanding could cause poll to enter a busy-waiting loop.
521 - document the new IO::AIO::poll_cb result value.
522
5233.02 Mon May 12 02:32:02 CEST 2008
524 - fix a memory leak on aio_readlink.
525 - bring back working fchmod.
526 - nop and busy now set result to 0.
527 - set errno to ENOMEM when allocation fails.
528
5293.01 Sun May 11 03:07:03 CEST 2008
530 - (libeio) make it compile on systems without readahead or readdir_r.
531 - (libeio) improve configure check for readahead availability.
532 - do not try to link against -lrt.
533 - use a separate configure script for IO::AIO (not the libeio one).
534
5353.0 Sun May 11 00:57:14 CEST 2008
536 - added bin/treescan to the distribution.
537 - switched to using libeio.
538 - LOTS OF INCOMPATIBLE CHANGES:
539 - remove signal functionality, it is not worth the effort.
540 - max_outstanding no longer returns the previous number of requests.
541 - poll_cb no longer returns number of requests.
542
5432.62 Sat Apr 26 13:59:33 CEST 2008
544 - port to solaris perls configured for old posix
545 (analysed by Jost Krieger).
546 - keep a reference to the perl filehandle object in aio_close,
547 so it doesn't get closed prematurely, leading to ugly races.
548
5492.61 Wed Apr 16 18:45:02 CEST 2008
550 - fix treescan output duplication and improve output ordering.
551 also display files given on the commandline.
552 - use a different algorithm for aio_close that is faster
553 and probably has even lower chances of blocking.
554 - do our own stack memory management for threads - linux
555 allocates outrageous amounts of VM (not so bad unless you
556 use mlockall...), which severely limits the number of threads
557 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
558 and 4096 * sizeof (long) (usually this is 16..64k).
559
5602.6 Sun Mar 30 08:28:11 CEST 2008
561 - added aio_sync.
562 - added aio_pathsync.
563 - fix prototypes of (void) functions.
564
5652.51 Sat Oct 6 16:04:54 CEST 2007
566 - perlio isn't generally threadsafe, so aio_close could not work reliably.
567 aio_close now tries a safe hack that might not be that asynchronous
568 (see the manpage for details).
569 - discard callback return values as to not grow the stack endlessly
570 when poll_cb handles many requests without returning.
571 - minor code cleanups.
572
5732.5 Thu Oct 4 14:49:08 CEST 2007
574 - replaced _fd2fh with faster xs code.
575 - aio_close will now try to do "the right thing" and thus might
576 work sensibly for the very first time.
577
5782.41 Mon Sep 24 21:28:21 CEST 2007
579 - after fork, invest some work to make sure that the poll_fileno
580 stays stable (by dup2'ing the new fd over the old one), to make
581 it easier for programs/libs that don't control their forking
582 behaviour and cannot recreate their watchers.
583
5842.4 Sun Aug 5 18:44:22 CEST 2007
585 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
586 successfully demonstrated that you can block on futimes...).
587 - allow undef as fileoffset for aio_read/write and use read/write(2)
588 internally (useful for sockets or O_APPEND handles).
589 - allow undef for length in aio_write.
590 - negative dataoffsets work as expected now in aio_read/aio_write.
591 - use NV instead of UV for 32 bit perls and file offsets, as NVs
592 have a larger range then.
593 - shared code between BDB and IO::AIO.
594 - aio_busy was completely broken. now fixed.
595 - readahead emulation now returns something.
596 - correctly set errno to ENOSYS on unimplemented functions
597 (should never happen, though).
598 - large changes to make it partially compile and run on win32,
599 but win32 lacks too much functionality, and perl overrides way
600 too many functions with crashing versions.
601
6022.33 Tue Jan 23 23:55:41 CET 2007
603 - fix install path (Andreas J. Koenig).
604
6052.32 Mon Jan 22 16:56:23 CET 2007
606 - added aio_rmtree.
607 - wow, aio_mkdir was missing.
608 - aio_load did return undef on error, not -1.
609 - use prefixexp not prefix in autoconf.pm
610 (suggested by ... rt.cpan.org unreachable).
611 - avoid installing autoconf.pm.
612
6132.31 Sat Jan 6 03:46:02 CET 2007
614 - added aio_load.
615
6162.3 Sat Dec 23 05:48:07 CET 2006
617 - fix off-by-one bug in aio_read, causing memory corruption
618 or crashes.
619
6202.21 Fri Dec 22 05:03:38 CET 2006
621 - minor doc updates.
622 - minor cleanups.
623 - IO::AIO::poll returns request count.
624 - undocumented and unfinished async-signal-reporting.
625
6262.2 Tue Oct 31 00:31:00 CET 2006
627 - minor doc updates.
628 - added aio_readlink.
629 - properly zero-terminate aio_read buffer.
630 - fix aio_read/write with nonzero dataoffset.
631 - reduced size of aio request structure.
632 - better diagnostics when pathnames etc. are not byte-encoded;
633 do not leak request in that case, either.
634
6352.1 Sun Oct 29 02:01:57 CET 2006
636 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
637 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
638 - fix a bug in aio_move where it would fail everytime
639 it would have to copy files manually.
640 - doc updates.
641 - start threads only on (very low) demand.
642 - end superfluous threads automatically after 10s idling.
643 - add IO::AIO::max_idle to control this.
644 - some tuning applied to random places.
645 - add aio_mknod.
646
6472.0 Thu Oct 26 18:27:58 CEST 2006
648 - minor incompatibility: max_outstanding semantics have changed.
649 - major rewrite, consider all functionality EXPERIMENTAL.
650 - aio requests can be cancelled.
651 - callbacks can be (re-)set later.
652 - aio requests can choose between 9 priorities.
653 - add aio_group: aio requests can be grouped
654 into composite requests.
655 - generator interface for groups.
656 - add IO::AIO::poll_some.
657 - major documentation improvements.
658 - very minor bugfixes.
659 - add aio_nop for dummy requests.
660 - add aio_busy mainly for benchmarking and debugging.
661 - use "fast" mutexes on linux.
662 - use dynamic (and larger) buffers instead of
663 putting them onto the stack.
664 - optimise x86 and amd64 a bit.
665 - better error checking when ENOMEM.
666 - hopefully fix mem and dirp leaks on fork.
667 - warn about broken perl malloc.
668 - compiles on cygwin (but pread is broken on cygwin
669 which is not detected by autoconf, so you have to
670 edit autoconf/config.h yourself to enable emulation).
671
6721.8 Sat Jun 24 22:20:44 CEST 2006
673 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
674
6751.73 Wed Mar 1 22:49:32 CET 2006
676 - codename "jost"
677 - AIX/Solaris(?) aren't being helpful again, hardcode a value
678 for NAME_MAX and drive with your eyes closed (reported by
679 wcooley@nakedape.cc).
680
6811.72 Thu Feb 2 00:40:44 CET 2006
682 - another minor bug in aio_scandir, again, the callback was called
683 twice when the directory can't be stat'ed.
684
6851.71 Mon Dec 26 20:20:03 CET 2005
686 - grr, another minor bug in aio_scandir, this time resulting
687 in a runtime error.
688
6891.7 Mon Dec 26 19:29:48 CET 2005
690 - aio_scandir errornously called callback twice in some cases.
691 - added AnyEvent example.
692
6931.61 Wed Sep 7 19:40:42 CEST 2005
694 - no longer include $Config{libs}, as distros include too much
695 garbage in there that is not installed on typical systems
696 (for example, debian links perl against -lgdbm and many more
697 libraries despite perl not needing it, slowing down startup and
698 wasting memory).
699
7001.6 Tue Aug 30 17:44:44 CEST 2005
701 - added aio_readdir, aio_scandir.
702 - added aio_sendfile, including sendfile emulation when sendfile
703 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
704 support is unavailable on my solaris 8 machine, but preliminary
705 code is there. What's lacking is configury stuff and testing...).
706
7071.5 Sat Aug 20 02:32:19 CEST 2005
4 - create the aio threads on demand only. 708 - create the aio threads on demand only (good after forking).
5 - somebody nagged about C89 compatibility, so this release should 709 - somebody nagged about C89 compatibility, so this release should
6 be C89 compatible, but no guarentees for future ones. 710 be C89 compatible, but no guarantees for future ones.
711 - abort when the configure script fails.
7 712
81.4 Wed Aug 17 08:07:27 CEST 2005 7131.4 Wed Aug 17 08:07:27 CEST 2005
9 - forget to recreate the pipe after forking, this could cause 714 - forgot to recreate the pipe after forking, this could cause
10 deadlocks. 715 deadlocks.
11 716
121.3 Wed Aug 17 07:25:54 CEST 2005 7171.3 Wed Aug 17 07:25:54 CEST 2005
13 - properly propagate exceptions from callbacks, instead of silently 718 - properly propagate exceptions from callbacks, instead of silently
14 eating them. 719 eating them.
