404.53 Tue Aug 14 11:27:50 CEST 2018
41 - add $Config{libs} to LIBS for configure, to work around systems
42 with broken library dependencies (... openbsd).
43
444.52 Sun Aug 12 08:09:45 CEST 2018
45 - config.h.in was missing in distribution.
46
474.51 Sun Aug 12 07:24:14 CEST 2018
48 - complete rework of the autoconf framework: IO::AIO now uses its own
49 config.h, separate from libeio, and tries to test the actual perl
50 environment, not the standard system environment.
51 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
52 stat functions.
53 - removed non-portable C++ syntax from eio.c.
54 - try to fix readdir tests on cygwin spuriously failing.
55
564.5 Wed Aug 1 00:23:55 CEST 2018
57 - aio_mtouch touch all pages as requested, not just the first page in most cases.
58 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
59 and MREMAP_FIXED.
60 - add O_ACCMODE.
61 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
62
634.4 Tue Feb 20 07:54:12 CET 2018
64 - new aio_slurp request.
65 - add (experimental) IO::AIO::eventfd and timerfd* function.
66 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
67 - point out that aio_copy overwrites existing files.
68 - removed filesystem magic number table from aio_statvfs docs as
69 statvfs doesn't actually return this info at all (statfs does).
70 - add a bunch of (mostly linux-specific) constants for use in ioctls
71 (see aio_ioctl docs).
72 - treescan now has a proper manpage and useful --help output.
73 - new option --sync in treescan, to sync everything in a subtree.
74 - changed default for aio_msync flags to MSYNC_SYNC.
75 - document offset/length behaviour of mprotect/madvise.
76 - support linux's renameat2 (via aio_rename2).
77 - add aio_rename2, an aio_rename with flags.
78 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
79 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
80 - (libeio) use posix_close if available.
81 - (libeio) internal close() calls no longer disturb errno.
82 - add IO:AIO::FALLOC_FL_UNSHARE.
83 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
84 and better eventfd detection.
85
864.34 Sun May 1 19:18:24 CEST 2016
87 - def0.h was not properly generated during previous release, causing
88 compile errors on various platforms.
89 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
90 - removed duplicate definition of MAP_HUGETLB, that was found due to
91 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
92 - added (untested!) aio_fcntl, aio_ioctl requests.
93 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
94 as manpages-dev originally claimed.
95
964.33 Mon Jan 18 12:50:10 CET 2016
97 - add IO::AIO::pipe2 function.
98 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
99 constants.
100 - added support for O_TMPFILE and O_PATH constants.
101 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
102 consdtants, whether they can be sensibly used or not.
103 - use NO_INIT where applicable.
104 - update libecb.
105 - added stability canary support.

107
1084.32 Wed Feb 11 20:32:11 CET 2015
109 - replace off_t by STRLEN where appropriate, should not result in
110 user-visible changes.
111 - update ecb.h for C11 compatibility.
112
1134.31 Tue Jun 3 03:29:27 CEST 2014
114 - work around more 5.20 bugs. backwards compatibility my ass.
115
1164.3 Fri Apr 11 06:22:38 CEST 2014
117 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
118 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
119 in 5.18. What's so attractive about giving a shit about backwards
120 compatibility - I will never understand.
121
1224.2 Sat Jan 25 01:13:14 CET 2014
123 - aio_group could corrupt memory because it didn't restore
124 the stack after req_submit.
125 - be more careful on (e.g. permission) errors in bin/treescan.
126 - work around changes in ExtUtils::MakeMaker.
127 - (libeio) implement aio_realpath for win32.
128 - (xthread) work around compile time bugs in ptw32.
129 - added IO::AIO::pipesize.
130 - (libecb) insignificant update.
131
1324.19 Sun Jan 6 12:47:26 CET 2013
133 - avoid endless loop in fiemap with some XFS files.
134 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
135 and call rename/rmdir instead of renameat/unlinkat.
136
1374.18 Thu Oct 11 07:01:26 CEST 2012
138 - fix unintended xthread_create by intentionalising it :)
139
1404.17 Thu Oct 11 05:19:47 CEST 2012
141 - rename aio_fallocate to aio_allocate, to match documentation.
142 - add list of linux fsid values to aio_statvfs docs.
143 - work around a bug in btrfs' FIEMAP ioctl implementation.
144 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
145 as per unix spec.
146
1474.16 Tue Aug 14 05:39:03 CEST 2012
148 - aio_statvfs was wromgly marked for wd emulation, causing
149 it to malfunction for paths.
150 - fix a crash in aio_fiemap, when used on ranges without any
151 extents.
152 - work around linux kernel bug (at least in 3.2): kernel might
153 trash fiemap input arguments.
154 - work around linux kernel bug (at least in 3.2): kernel does not
155 set FIEMAP_EXTENT_LAST on last segment.
156 - work around linux kernel bug (at least in 3.2): kernel silently
157 truncates segment count if a file.
158 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
159 to quick overview.
160 - splice can corrupt data.
161 - (libeio) remove pread/pwrite emulation.
162 - do not grow mmaped scalars in aio_read.
163 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
164 - provide pread/pwrite for win32, making it link again on native win32.
165
1664.15 Tue Apr 10 06:59:00 CEST 2012
167 - always include linux/types.h for fiemap, for compatibility to
168 ancient systems (Paul Howarth).
169 - experimental support for IO::AIO::splice and ::tee (no aio_...).
170 - provide SEEK_HOLE and SEEK_DATA, if available.
171 - work around (again!) an immensely stupid bug in RHEL, defining
172 autoconf macros in linux system headers (analysed by Paul Howarth).
173
1744.14 Sat Apr 7 02:45:18 CEST 2012
175 - fix stat structure usage on windows, which caused bogus stat results.
176 - (libeio) make readahead emulation behave more like actual readahead by never failing.
177 - new request aio_seek.
178 - new request aio_fiemap.
179 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
180
1814.12 Fri Dec 30 08:51:25 CET 2011
182 - realpath would return a random value if the name was too long,
183 instead of -1.
184 - port to c89.
185
1864.11 Mon Oct 10 00:24:11 CEST 2011
187 - libeio didn't compile on !linux (Paul Howarth).
188
1894.1 Sun Oct 9 10:24:11 CEST 2011
190 - IO::AIO did access uninitialised memory on unsuccessful stats.
191 - (libeio) added syncfs syscall wrapper.
192 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
193 - (libeio) support multiple indepenent working directories.
194 - applied speling corrections by Nicholas Bamber.
195 - tune treescan #threads and #outstanding requests a bit.
196 - reduce the number of file descriptors in use at any one time
197 in treescan, to avoid running out of them (and using too much ram).
198 - take advantage of working directoriy abstractions
199 in aio_scandir and treescan.
200 - reduce compiled size by ~10% by not inlining some key functionality.
201 - added --progress switch to treescan.
202
2034.0 Mon Jul 18 05:01:10 CEST 2011
204 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
205 see FORK BEHAVIOUR in manpage for details.
206 - passes testsuite on win32 now and may actually work
207 (activestate 5.10.1 / MSVC6, YMMV).
208 - (libeio) fix a deadlock where a wakeup signal could be missed when
209 a timeout occured at the same time.
210 - (libeio) added realpath.
211 - (libeio) added fallocate.
212 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
213 - (libeio) do not acquire any locks when forking.
214 - (libeio) use fewer time() syscalls when waiting for new requests.
215
2163.93 Wed Jun 29 23:44:18 CEST 2011
217 - ECB.H WAS MISSING.
218
2193.92 Wed Jun 29 14:45:41 CEST 2011
220 - ecb.h was missing.
221
2223.91 Wed Jun 29 13:24:42 CEST 2011
223 - (libeio) work around a Linux (and likely FreeBSD and other
224 kernels) bug where sendfile would not transfer all the requested
225 bytes on large transfers, using a heuristic.
226 - buggy sendfile caused aio_move/copy to sometimes fail for big
227 files (fortunately it checks that the whole file has been
228 transferred...)
229 - use libecb for higher performance and higher portability.
230 - (libeio) disable sendfile on darwin, it's too broken.
231 - disable fork tests on !linux, as only linux supports mixing
232 pthread and fork in perl.
233 - document the fact that fork doesn't work anymore when using
234 this module, on anything !GNU/Linux.
235 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
236 run on a 0.1MHz cpu. Or so.
237
2383.9 Fri May 27 02:43:47 CEST 2011
239 - (libeio) fix memory corruption in aio_readdirx for the flags
240 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
241 - add lots of newer POSIX and GNU/Linux-specific open
242 flags.
243
2443.8 Sun Mar 27 12:25:33 CEST 2011
245 - use nonstandard but maybe-working-on-bsd fork technique.
246 - support a max_idle value of 0.
247 - support setting of idle timeout value (IO::AIO::idle_timeout).
248
2493.72 Fri Feb 11 04:25:38 CET 2011
250 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
251 - aio_mknod always used a dev_t value of 0.
252 - new treescan option: --grep.
253 - add more S_IF macros, and major/minor/makedev "macros".
254
2553.71 Thu Dec 30 08:18:46 CET 2010
256 - the numerical result value passed to callbacks did not stringify
257 correctly, due to internal reuse and failure to reset the sv flags.
258 - actually test for posix_[mf]advise, as at least uClibc defines
259 _POSIX_ADVISORY_INFO without actually having any of the required
260 funcitonality. ugh.
261
2623.7 Mon Nov 1 23:00:34 CET 2010
263 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
264 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
265 - document the sad state of affairs w.r.t. pthread on many bsds.
266 - do not enable mmap on systems without _POSIX_MAPPED_FILES
267 (openbsd 4.8).
268 - do not leak memory in IO::AIO::mmap when the scalar already
269 had string-data.
270 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
271 them.
272 - cache the result IV, for a minor speedup in the common case.
273 - croak when an mmapped-scalar changes location, to detect
274 user-errors better.
275 - fix aio_readlink prototype.
276
2773.65 Wed Mar 31 02:45:05 CEST 2010
278 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
279 cut off long pathnames in aio_readlink (based on patch by
280 Rasmus Andersson).
281 - a double fork partially killed the event pipe (great testcase
282 by dormando). affects IO::AIO, BDB and Async::Interrupt.
283 - suck steve's dick and rename our symbols to avoid colliding
284 with nonstandard identifier spam on the broken os x pseudo-os.
285 affects IO::AIO and BDB.
286
2873.6 Mon Jan 11 00:43:39 CET 2010
288 - (libeio) more fixes for the freebsd/apple sendfile - broken by
289 manpage standards, but apparently correct accoridng to actual
290 kernel sources.
291 - add IO::AIO::mmap/munmap support.
292 - add IO::AIO::m(un)lockall support.
293 - clean up manpage.
294
2953.5 Thu Jan 7 21:25:04 CET 2010
296 - (liebio) fix freebsd sendfile (Vanilla Hsu).
297 - (libeio) also fix darwin sendfile that suffered from a similar bug.
298 - add aio_statvfs as interface to statvfs/fstatvfs.
299 - work around buggy symlink() on cygwin in the testsuite.
300 - wtf. freebsd-8.0 actually passes the testsuite! I knew
301 they could implement fork and semaphores one day! cheers!
302
3033.4 Sat Jan 2 15:13:04 CET 2010
304 - (libeio) max_poll_time was not properly converted to ticks.
305 - clarify cancel_subs description.
306 - IO::AIO::sendfile did not actually return the return value
307 from the sendfile call.
308 - implement aio_msync, aio_mtouch.
309 - (libeio) tentatively support darwin in sendfile.
310
3113.31 Thu Nov 12 02:14:29 CET 2009
312 - fix result status documentation of aio_copy, aio_move.
313 - speed up object creation considerably by avoiding
314 hash lookups.
315
3163.3 Wed Aug 5 13:52:58 CEST 2009
317 - use common::sense.
318 - use common schmorp.h header.
319 - allow integers (file descriptors) in addition to file handles.
320 - take advantage of linux' eventfd (but it seems slower on smp?).
321 - use poll not select on posix platforms.
322
3233.261 Wed Jul 1 10:11:51 CEST 2009
324 - more 0S X workarounds (patch by Tokuhiro Matsuno).
325
3263.26 Tue Jun 30 09:33:26 CEST 2009
327 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
328 try to work around this horribly broken OS in a somewhat hackish
329 way. might help other os's too.
330
3313.25 Sat Jun 27 05:18:26 CEST 2009
332 - added IO::AIO::fadvise and IO::AIO::sendfile.
333 - (libeio) replaced quicksort+insertion sort by a tuned radix
334 sort + insertion sort, resulting in comparable runtime (usually
335 faster) to the old version, but without any ill side effects on
336 degenerated (for quicksort) data.
337 - (libeio) correctly sort dirs by inodes if we have perfect type
338 knowledge and DIRS_FIRST is used.
339 - (libeio) internally the wrong DT_* constants were used, but no
340 known system has differing EIO_DT_*/DT_* values, so not an issue.
341 - removed a (harmless) assert that was left over on the code
342 but should not have been.
343 - use more correct types (change IO length from IV to VAL64,
344 which makes a difference on systems without 64 bit perls).
345
3463.23 Sat Jun 13 16:57:58 CEST 2009
347 - fix off-by-one bug in aio_readdir that was introduced in the
348 rushed 3.22 release.
349
3503.22 Sat Jun 13 15:32:40 CEST 2009
351 - speed up readdirx sort algorithm slightly.
352 - bin/treescan was missing from distro tarball.
353
3543.21 Fri Jun 12 18:45:53 CEST 2009
355 - new options --dirs and --files for treescan.
356 - install bin/treescan by default.
357 - (libeio) aio_readdir can now be cancelled while executing.
358 - fix a printf format string for 64 bit systems (could lead
359 to problems on big endian 64 bit systems).
360 - do not use qsort() but our own algorithm: glibc initialises
361 the whole locale and I/O subsystem inside qsort, causing
362 a stack overflow on 32 bit machines. The new sort uses much less
363 stack and is more than twice as fast in typical situations.
364
3653.2 Sun Jun 7 20:30:05 CEST 2009
366 - (libeio) pwrite emulation was even more flawed than intended and did
367 not restore the file offset.
368 - add aio_readdirx, which can return inode and filetype and sort
369 the names in various ways.
370 - unfortunately, utime, chmod, chown on an open file that has just
371 been written can easily block, which caused aio_copy to block the
372 process. no more!
373 - no longer rely on dst path in aio_copy when futime is available.
374
3753.19 Tue Apr 21 22:05:21 CEST 2009
376 - more perl 5.10 workarounds for aio_read and write.
377 - aio_write no longer modifies the sv (if possible).
378 - aio_read now works correctly with magic values.
379
3803.18 Sun Apr 19 21:17:32 CEST 2009
381 - better diagnostics when some aio_* functions get passed an illegal fh.
382 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
383
3843.17 Thu Nov 20 08:45:36 CET 2008
385 - (libeio) added aio_sync_file_range (untested).
386 - add aio_busy to @IO::AIO::AIO_REQ.
387
3883.16 Wed Oct 22 18:28:01 CEST 2008
389 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
390 part to improve portability to perl 5.8 (reported by szymon).
391
3923.15 Mon Oct 13 00:39:55 CEST 2008
393 - automatic removal of feeders was broken.
394 - (libeio) use a more robust method to detect whether a feeder
395 has added something to the group or not.
396
3973.1 Thu Oct 2 13:34:40 CEST 2008
398 - pre-deref the passed callback object, for increased speed
399 and decreased memory usage.
400 - call on_next_submit callback even for aio_group - impact unknown,
401 but seems more correct.
402 - $req->cb now returns the original callback.
403 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
404 requiring a thread switch.
405 - (libeio) status code of aio_futime and aio_utime was always passed 0.
406 - do some other ยต-optimisations.
407
4083.07 Sat Aug 2 16:06:13 CEST 2008
409 - do not include LIBS in autoconf tests.
410
4113.06 Tue Jul 15 12:41:32 CEST 2008
412 - move preadwritelock definition before it's first reference,
413 to make it compile again on broken platforms (they still exist)
414 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
415
4163.05 Thu Jun 19 23:23:52 CEST 2008
417 - work around perl overriding readdir etc. with thread-unsafe
418 (sic!) versions.
419
4203.04 Wed Jun 18 01:35:38 CEST 2008
421 - (libeio) fix eio_mknod, which confused it's arguments.
422 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
423 is stupid.
424 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
425 - (libeio) fix a bug that could potentially cause IO::AIO
426 not to get initialised properly.
427
4283.03 Thu May 29 05:33:30 CEST 2008
429 - (libeio) correctly call pthread_attr_destroy ().
430 - (libeio) work around broken bsd headers once more.
431 - reduce shared library size again by not including wrappers.
432 - max_outstanding could cause poll to enter a busy-waiting loop.
433 - document the new IO::AIO::poll_cb result value.
434
4353.02 Mon May 12 02:32:02 CEST 2008
436 - fix a memory leak on aio_readlink.
437 - bring back working fchmod.
438 - nop and busy now set result to 0.
439 - set errno to ENOMEM when allocation fails.
440
4413.01 Sun May 11 03:07:03 CEST 2008
442 - (libeio) make it compile on systems without readahead or readdir_r.
443 - (libeio) improve configure check for readahead availability.
444 - do not try to link against -lrt.
445 - use a separate configure script for IO::AIO (not the libeio one).
446
4473.0 Sun May 11 00:57:14 CEST 2008
448 - added bin/treescan to the distribution.
449 - switched to using libeio.
450 - LOTS OF INCOMPATIBLE CHANGES:
451 - remove signal functionality, it is not worth the effort.
452 - max_outstanding no longer returns the previous number of requests.
453 - poll_cb no longer returns number of requests.
454
4552.62 Sat Apr 26 13:59:33 CEST 2008
456 - port to solaris perls configured for old posix
457 (analysed by Jost Krieger).
458 - keep a reference to the perl filehandle object in aio_close,
459 so it doesn't get closed prematurely, leading to ugly races.
460
4612.61 Wed Apr 16 18:45:02 CEST 2008
462 - fix treescan output duplication and improve output ordering.
463 also display files given on the commandline.
464 - use a different algorithm for aio_close that is faster
465 and probably has even lower chances of blocking.
466 - do our own stack memory management for threads - linux
467 allocates outrageous amounts of VM (not so bad unless you
468 use mlockall...), which severely limits the number of threads
469 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
470 and 4096 * sizeof (long) (usually this is 16..64k).
471
4722.6 Sun Mar 30 08:28:11 CEST 2008
473 - added aio_sync.
474 - added aio_pathsync.
475 - fix prototypes of (void) functions.
476
4772.51 Sat Oct 6 16:04:54 CEST 2007
478 - perlio isn't generally threadsafe, so aio_close could not work reliably.
479 aio_close now tries a safe hack that might not be that asynchronous
480 (see the manpage for details).
481 - discard callback return values as to not grow the stack endlessly
482 when poll_cb handles many requests without returning.
483 - minor code cleanups.
484
4852.5 Thu Oct 4 14:49:08 CEST 2007
486 - replaced _fd2fh with faster xs code.
487 - aio_close will now try to do "the right thing" and thus might
488 work sensibly for the very first time.
489
4902.41 Mon Sep 24 21:28:21 CEST 2007
491 - after fork, invest some work to make sure that the poll_fileno
492 stays stable (by dup2'ing the new fd over the old one), to make
493 it easier for programs/libs that don't control their forking
494 behaviour and cannot recreate their watchers.
495
4962.4 Sun Aug 5 18:44:22 CEST 2007
497 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
498 successfully demonstrated that you can block on futimes...).
499 - allow undef as fileoffset for aio_read/write and use read/write(2)
500 internally (useful for sockets or O_APPEND handles).
501 - allow undef for length in aio_write.
502 - negative dataoffsets work as expected now in aio_read/aio_write.
503 - use NV instead of UV for 32 bit perls and file offsets, as NVs
504 have a larger range then.
505 - shared code between BDB and IO::AIO.
506 - aio_busy was completely broken. now fixed.
507 - readahead emulation now returns something.
508 - correctly set errno to ENOSYS on unimplemented functions
509 (should never happen, though).
510 - large changes to make it partially compile and run on win32,
511 but win32 lacks too much functionality, and perl overrides way
512 too many functions with crashing versions.
513
5142.33 Tue Jan 23 23:55:41 CET 2007
515 - fix install path (Andreas J. Koenig).
516
5172.32 Mon Jan 22 16:56:23 CET 2007
518 - added aio_rmtree.
519 - wow, aio_mkdir was missing.
520 - aio_load did return undef on error, not -1.
521 - use prefixexp not prefix in autoconf.pm
522 (suggested by ... rt.cpan.org unreachable).
523 - avoid installing autoconf.pm.
524
5252.31 Sat Jan 6 03:46:02 CET 2007
526 - added aio_load.
527
5282.3 Sat Dec 23 05:48:07 CET 2006
529 - fix off-by-one bug in aio_read, causing memory corruption
530 or crashes.
531
5322.21 Fri Dec 22 05:03:38 CET 2006
533 - minor doc updates.
534 - minor cleanups.
535 - IO::AIO::poll returns request count.
536 - undocumented and unfinished async-signal-reporting.
537
5382.2 Tue Oct 31 00:31:00 CET 2006
539 - minor doc updates.
540 - added aio_readlink.
541 - properly zero-terminate aio_read buffer.
542 - fix aio_read/write with nonzero dataoffset.
543 - reduced size of aio request structure.
544 - better diagnostics when pathnames etc. are not byte-encoded;
545 do not leak request in that case, either.
546
5472.1 Sun Oct 29 02:01:57 CET 2006
548 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
549 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
550 - fix a bug in aio_move where it would fail everytime
551 it would have to copy files manually.
552 - doc updates.
553 - start threads only on (very low) demand.
554 - end superfluous threads automatically after 10s idling.
555 - add IO::AIO::max_idle to control this.
556 - some tuning applied to random places.
557 - add aio_mknod.
558
5592.0 Thu Oct 26 18:27:58 CEST 2006
560 - minor incompatibility: max_outstanding semantics have changed.
561 - major rewrite, consider all functionality EXPERIMENTAL.
562 - aio requests can be cancelled.
563 - callbacks can be (re-)set later.
564 - aio requests can choose between 9 priorities.
565 - add aio_group: aio requests can be grouped
566 into composite requests.
567 - generator interface for groups.
568 - add IO::AIO::poll_some.
569 - major documentation improvements.
570 - very minor bugfixes.
571 - add aio_nop for dummy requests.
572 - add aio_busy mainly for benchmarking and debugging.
573 - use "fast" mutexes on linux.
574 - use dynamic (and larger) buffers instead of
575 putting them onto the stack.
576 - optimise x86 and amd64 a bit.
577 - better error checking when ENOMEM.
578 - hopefully fix mem and dirp leaks on fork.
579 - warn about broken perl malloc.
580 - compiles on cygwin (but pread is broken on cygwin
581 which is not detected by autoconf, so you have to
582 edit autoconf/config.h yourself to enable emulation).
583
5841.8 Sat Jun 24 22:20:44 CEST 2006
585 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
586
5871.73 Wed Mar 1 22:49:32 CET 2006
588 - codename "jost"
589 - AIX/Solaris(?) aren't being helpful again, hardcode a value
590 for NAME_MAX and drive with your eyes closed (reported by
591 wcooley@nakedape.cc).
592
5931.72 Thu Feb 2 00:40:44 CET 2006
594 - another minor bug in aio_scandir, again, the callback was called
595 twice when the directory can't be stat'ed.
596
5971.71 Mon Dec 26 20:20:03 CET 2005
598 - grr, another minor bug in aio_scandir, this time resulting
599 in a runtime error.
600
6011.7 Mon Dec 26 19:29:48 CET 2005
602 - aio_scandir errornously called callback twice in some cases.
603 - added AnyEvent example.
604
6051.61 Wed Sep 7 19:40:42 CEST 2005
606 - no longer include $Config{libs}, as distros include too much
607 garbage in there that is not installed on typical systems
608 (for example, debian links perl against -lgdbm and many more
609 libraries despite perl not needing it, slowing down startup and
610 wasting memory).
611
6121.6 Tue Aug 30 17:44:44 CEST 2005
613 - added aio_readdir, aio_scandir.
614 - added aio_sendfile, including sendfile emulation when sendfile
615 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
616 support is unavailable on my solaris 8 machine, but preliminary
617 code is there. What's lacking is configury stuff and testing...).
618
6191.5 Sat Aug 20 02:32:19 CEST 2005
4 - create the aio threads on demand only. 620 - create the aio threads on demand only (good after forking).
5 - somebody nagged about C89 compatibility, so this release should 621 - somebody nagged about C89 compatibility, so this release should
6 be C89 compatible, but no guarentees for future ones. 622 be C89 compatible, but no guarantees for future ones.
623 - abort when the configure script fails.
7 624
81.4 Wed Aug 17 08:07:27 CEST 2005 6251.4 Wed Aug 17 08:07:27 CEST 2005
9 - forget to recreate the pipe after forking, this could cause 626 - forgot to recreate the pipe after forking, this could cause
10 deadlocks. 627 deadlocks.
11 628
121.3 Wed Aug 17 07:25:54 CEST 2005 6291.3 Wed Aug 17 07:25:54 CEST 2005
