44
45 - add MADV_FREE constant.
46 - add a bunch of (mostly linux-specific) constants for use in ioctls
47 (see aio_ioctl docs).
48 - treescan now has a proper manpage and useful --help output.
49 - new option --sync in treescan, to sync everything in a subtree.
50
514.34 Sun May 1 19:18:24 CEST 2016
52 - def0.h was not properly generated during previous release, causing
53 compile errors on various platforms.
54 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
55 - removed duplicate definition of MAP_HUGETLB, that was found due to
56 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
57 - added (untested!) aio_fcntl, aio_ioctl requests.
58 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
59 as manpages-dev originally claimed.
60
614.33 Mon Jan 18 12:50:10 CET 2016
62 - add IO::AIO::pipe2 function.
63 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
64 constants.
65 - added support for O_TMPFILE and O_PATH constants.
66 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK

72
734.32 Wed Feb 11 20:32:11 CET 2015

75 user-visible changes.
76 - update ecb.h for C11 compatibility.
77
784.31 Tue Jun 3 03:29:27 CEST 2014
79 - work around more 5.20 bugs. backwards compatibility my ass.
80
814.3 Fri Apr 11 06:22:38 CEST 2014
82 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
83 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
84 in 5.18. What's so attractive about giving a shit about backwards
85 compatibility - I will never understand.
86
874.2 Sat Jan 25 01:13:14 CET 2014
88 - aio_group could corrupt memory because it didn't restore
89 the stack after req_submit.
90 - be more careful on (e.g. permission) errors in bin/treescan.
91 - work around changes in ExtUtils::MakeMaker.
92 - (libeio) implement aio_realpath for win32.

98 - avoid endless loop in fiemap with some XFS files.
99 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]

101
1024.18 Thu Oct 11 07:01:26 CEST 2012
103 - fix unintended xthread_create by intentionalising it :)
104

106 - rename aio_fallocate to aio_allocate, to match documentation.
107 - add list of linux fsid values to aio_statvfs docs.
108 - work around a bug in btrfs' FIEMAP ioctl implementation.
109 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
110 as per unix spec.
111
1124.16 Tue Aug 14 05:39:03 CEST 2012
113 - aio_statvfs was wromgly marked for wd emulation, causing
114 it to malfunction for paths.
115 - fix a crash in aio_fiemap, when used on ranges without any
116 extents.
117 - work around linux kernel bug (at least in 3.2): kernel might
118 trash fiemap input arguments.
119 - work around linux kernel bug (at least in 3.2): kernel does not
120 set FIEMAP_EXTENT_LAST on last segment.
121 - work around linux kernel bug (at least in 3.2): kernel silently
122 truncates segment count if a file.
123 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
124 to quick overview.
125 - splice can corrupt data.
126 - (libeio) remove pread/pwrite emulation.
127 - do not grow mmaped scalars in aio_read.
128 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
129 - provide pread/pwrite for win32, making it link again on native win32.
130
1314.15 Tue Apr 10 06:59:00 CEST 2012
132 - always include linux/types.h for fiemap, for compatibility to
133 ancient systems (Paul Howarth).
134 - experimental support for IO::AIO::splice and ::tee (no aio_...).
135 - provide SEEK_HOLE and SEEK_DATA, if available.
136 - work around (again!) an immensely stupid bug in RHEL, defining
137 autoconf macros in linux system headers (analysed by Paul Howarth).
138
1394.14 Sat Apr 7 02:45:18 CEST 2012
140 - fix stat structure usage on windows, which caused bogus stat results.
141 - (libeio) make readahead emulation behave more like actual readahead by never failing.
142 - new request aio_seek.
143 - new request aio_fiemap.
144 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
145
1464.12 Fri Dec 30 08:51:25 CET 2011
147 - realpath would return a random value if the name was too long,
148 instead of -1.
149 - port to c89.
150
1514.11 Mon Oct 10 00:24:11 CEST 2011
152 - libeio didn't compile on !linux (Paul Howarth).
153
1544.1 Sun Oct 9 10:24:11 CEST 2011
155 - IO::AIO did access uninitialised memory on unsuccessful stats.
156 - (libeio) added syncfs syscall wrapper.
157 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
158 - (libeio) support multiple indepenent working directories.
159 - applied speling corrections by Nicholas Bamber.
160 - tune treescan #threads and #outstanding requests a bit.
161 - reduce the number of file descriptors in use at any one time
162 in treescan, to avoid running out of them (and using too much ram).
163 - take advantage of working directoriy abstractions
164 in aio_scandir and treescan.
165 - reduce compiled size by ~10% by not inlining some key functionality.
166 - added --progress switch to treescan.
167
1684.0 Mon Jul 18 05:01:10 CEST 2011
169 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
170 see FORK BEHAVIOUR in manpage for details.
171 - passes testsuite on win32 now and may actually work
172 (activestate 5.10.1 / MSVC6, YMMV).
173 - (libeio) fix a deadlock where a wakeup signal could be missed when
174 a timeout occured at the same time.
175 - (libeio) added realpath.
176 - (libeio) added fallocate.
177 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
178 - (libeio) do not acquire any locks when forking.
179 - (libeio) use fewer time() syscalls when waiting for new requests.
180
1813.93 Wed Jun 29 23:44:18 CEST 2011
182 - ECB.H WAS MISSING.
183
1843.92 Wed Jun 29 14:45:41 CEST 2011
185 - ecb.h was missing.
186
1873.91 Wed Jun 29 13:24:42 CEST 2011
188 - (libeio) work around a Linux (and likely FreeBSD and other
189 kernels) bug where sendfile would not transfer all the requested
190 bytes on large transfers, using a heuristic.
191 - buggy sendfile caused aio_move/copy to sometimes fail for big
192 files (fortunately it checks that the whole file has been
193 transferred...)
194 - use libecb for higher performance and higher portability.
195 - (libeio) disable sendfile on darwin, it's too broken.
196 - disable fork tests on !linux, as only linux supports mixing
197 pthread and fork in perl.
198 - document the fact that fork doesn't work anymore when using
199 this module, on anything !GNU/Linux.
200 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
201 run on a 0.1MHz cpu. Or so.
202
2033.9 Fri May 27 02:43:47 CEST 2011
204 - (libeio) fix memory corruption in aio_readdirx for the flags
205 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
206 - add lots of newer POSIX and GNU/Linux-specific open
207 flags.
208
2093.8 Sun Mar 27 12:25:33 CEST 2011
210 - use nonstandard but maybe-working-on-bsd fork technique.
211 - support a max_idle value of 0.
212 - support setting of idle timeout value (IO::AIO::idle_timeout).
213
2143.72 Fri Feb 11 04:25:38 CET 2011
215 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
216 - aio_mknod always used a dev_t value of 0.
217 - new treescan option: --grep.
218 - add more S_IF macros, and major/minor/makedev "macros".
219
2203.71 Thu Dec 30 08:18:46 CET 2010
221 - the numerical result value passed to callbacks did not stringify
222 correctly, due to internal reuse and failure to reset the sv flags.
223 - actually test for posix_[mf]advise, as at least uClibc defines
224 _POSIX_ADVISORY_INFO without actually having any of the required
225 funcitonality. ugh.
226
2273.7 Mon Nov 1 23:00:34 CET 2010
228 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
229 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
230 - document the sad state of affairs w.r.t. pthread on many bsds.
231 - do not enable mmap on systems without _POSIX_MAPPED_FILES
232 (openbsd 4.8).
233 - do not leak memory in IO::AIO::mmap when the scalar already
234 had string-data.
235 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
236 them.
237 - cache the result IV, for a minor speedup in the common case.
238 - croak when an mmapped-scalar changes location, to detect
239 user-errors better.
240 - fix aio_readlink prototype.
241
2423.65 Wed Mar 31 02:45:05 CEST 2010
243 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
244 cut off long pathnames in aio_readlink (based on patch by
245 Rasmus Andersson).
246 - a double fork partially killed the event pipe (great testcase
247 by dormando). affects IO::AIO, BDB and Async::Interrupt.
248 - suck steve's dick and rename our symbols to avoid colliding
249 with nonstandard identifier spam on the broken os x pseudo-os.
250 affects IO::AIO and BDB.
251
2523.6 Mon Jan 11 00:43:39 CET 2010
253 - (libeio) more fixes for the freebsd/apple sendfile - broken by
254 manpage standards, but apparently correct accoridng to actual
255 kernel sources.
256 - add IO::AIO::mmap/munmap support.
257 - add IO::AIO::m(un)lockall support.
258 - clean up manpage.
259
2603.5 Thu Jan 7 21:25:04 CET 2010
261 - (liebio) fix freebsd sendfile (Vanilla Hsu).
262 - (libeio) also fix darwin sendfile that suffered from a similar bug.
263 - add aio_statvfs as interface to statvfs/fstatvfs.
264 - work around buggy symlink() on cygwin in the testsuite.
265 - wtf. freebsd-8.0 actually passes the testsuite! I knew
266 they could implement fork and semaphores one day! cheers!
267
2683.4 Sat Jan 2 15:13:04 CET 2010
269 - (libeio) max_poll_time was not properly converted to ticks.
270 - clarify cancel_subs description.
271 - IO::AIO::sendfile did not actually return the return value
272 from the sendfile call.
273 - implement aio_msync, aio_mtouch.
274 - (libeio) tentatively support darwin in sendfile.
275
2763.31 Thu Nov 12 02:14:29 CET 2009
277 - fix result status documentation of aio_copy, aio_move.
278 - speed up object creation considerably by avoiding
279 hash lookups.
280
2813.3 Wed Aug 5 13:52:58 CEST 2009
282 - use common::sense.
283 - use common schmorp.h header.
284 - allow integers (file descriptors) in addition to file handles.
285 - take advantage of linux' eventfd (but it seems slower on smp?).
286 - use poll not select on posix platforms.
287
2883.261 Wed Jul 1 10:11:51 CEST 2009
289 - more 0S X workarounds (patch by Tokuhiro Matsuno).
290
2913.26 Tue Jun 30 09:33:26 CEST 2009
292 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
293 try to work around this horribly broken OS in a somewhat hackish
294 way. might help other os's too.
295
2963.25 Sat Jun 27 05:18:26 CEST 2009
297 - added IO::AIO::fadvise and IO::AIO::sendfile.
298 - (libeio) replaced quicksort+insertion sort by a tuned radix
299 sort + insertion sort, resulting in comparable runtime (usually
300 faster) to the old version, but without any ill side effects on
301 degenerated (for quicksort) data.
302 - (libeio) correctly sort dirs by inodes if we have perfect type
303 knowledge and DIRS_FIRST is used.
304 - (libeio) internally the wrong DT_* constants were used, but no
305 known system has differing EIO_DT_*/DT_* values, so not an issue.
306 - removed a (harmless) assert that was left over on the code
307 but should not have been.
308 - use more correct types (change IO length from IV to VAL64,
309 which makes a difference on systems without 64 bit perls).
310
3113.23 Sat Jun 13 16:57:58 CEST 2009
312 - fix off-by-one bug in aio_readdir that was introduced in the
313 rushed 3.22 release.
314
3153.22 Sat Jun 13 15:32:40 CEST 2009
316 - speed up readdirx sort algorithm slightly.
317 - bin/treescan was missing from distro tarball.
318
3193.21 Fri Jun 12 18:45:53 CEST 2009
320 - new options --dirs and --files for treescan.
321 - install bin/treescan by default.
322 - (libeio) aio_readdir can now be cancelled while executing.
323 - fix a printf format string for 64 bit systems (could lead
324 to problems on big endian 64 bit systems).
325 - do not use qsort() but our own algorithm: glibc initialises
326 the whole locale and I/O subsystem inside qsort, causing
327 a stack overflow on 32 bit machines. The new sort uses much less
328 stack and is more than twice as fast in typical situations.
329
3303.2 Sun Jun 7 20:30:05 CEST 2009
331 - (libeio) pwrite emulation was even more flawed than intended and did
332 not restore the file offset.
333 - add aio_readdirx, which can return inode and filetype and sort
334 the names in various ways.
335 - unfortunately, utime, chmod, chown on an open file that has just
336 been written can easily block, which caused aio_copy to block the
337 process. no more!
338 - no longer rely on dst path in aio_copy when futime is available.
339
3403.19 Tue Apr 21 22:05:21 CEST 2009
341 - more perl 5.10 workarounds for aio_read and write.
342 - aio_write no longer modifies the sv (if possible).
343 - aio_read now works correctly with magic values.
344
3453.18 Sun Apr 19 21:17:32 CEST 2009
346 - better diagnostics when some aio_* functions get passed an illegal fh.
347 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
348
3493.17 Thu Nov 20 08:45:36 CET 2008
350 - (libeio) added aio_sync_file_range (untested).
351 - add aio_busy to @IO::AIO::AIO_REQ.
352
3533.16 Wed Oct 22 18:28:01 CEST 2008
354 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
355 part to improve portability to perl 5.8 (reported by szymon).
356
3573.15 Mon Oct 13 00:39:55 CEST 2008
358 - automatic removal of feeders was broken.
359 - (libeio) use a more robust method to detect whether a feeder
360 has added something to the group or not.
361
3623.1 Thu Oct 2 13:34:40 CEST 2008
363 - pre-deref the passed callback object, for increased speed
364 and decreased memory usage.
365 - call on_next_submit callback even for aio_group - impact unknown,
366 but seems more correct.
367 - $req->cb now returns the original callback.
368 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
369 requiring a thread switch.
370 - (libeio) status code of aio_futime and aio_utime was always passed 0.
371 - do some other ยต-optimisations.
372
3733.07 Sat Aug 2 16:06:13 CEST 2008
374 - do not include LIBS in autoconf tests.
375
3763.06 Tue Jul 15 12:41:32 CEST 2008
377 - move preadwritelock definition before it's first reference,
378 to make it compile again on broken platforms (they still exist)
379 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
380
3813.05 Thu Jun 19 23:23:52 CEST 2008
382 - work around perl overriding readdir etc. with thread-unsafe
383 (sic!) versions.
384
3853.04 Wed Jun 18 01:35:38 CEST 2008
386 - (libeio) fix eio_mknod, which confused it's arguments.
387 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
388 is stupid.
389 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
390 - (libeio) fix a bug that could potentially cause IO::AIO
391 not to get initialised properly.
392
3933.03 Thu May 29 05:33:30 CEST 2008
394 - (libeio) correctly call pthread_attr_destroy ().
395 - (libeio) work around broken bsd headers once more.
396 - reduce shared library size again by not including wrappers.
397 - max_outstanding could cause poll to enter a busy-waiting loop.
398 - document the new IO::AIO::poll_cb result value.
399
4003.02 Mon May 12 02:32:02 CEST 2008
401 - fix a memory leak on aio_readlink.
402 - bring back working fchmod.
403 - nop and busy now set result to 0.
404 - set errno to ENOMEM when allocation fails.
405
4063.01 Sun May 11 03:07:03 CEST 2008
407 - (libeio) make it compile on systems without readahead or readdir_r.
408 - (libeio) improve configure check for readahead availability.
409 - do not try to link against -lrt.
410 - use a separate configure script for IO::AIO (not the libeio one).
411
4123.0 Sun May 11 00:57:14 CEST 2008
413 - added bin/treescan to the distribution.
414 - switched to using libeio.
415 - LOTS OF INCOMPATIBLE CHANGES:
416 - remove signal functionality, it is not worth the effort.
417 - max_outstanding no longer returns the previous number of requests.
418 - poll_cb no longer returns number of requests.
419
4202.62 Sat Apr 26 13:59:33 CEST 2008
421 - port to solaris perls configured for old posix
422 (analysed by Jost Krieger).
423 - keep a reference to the perl filehandle object in aio_close,
424 so it doesn't get closed prematurely, leading to ugly races.
425
4262.61 Wed Apr 16 18:45:02 CEST 2008
427 - fix treescan output duplication and improve output ordering.
428 also display files given on the commandline.
429 - use a different algorithm for aio_close that is faster
430 and probably has even lower chances of blocking.
431 - do our own stack memory management for threads - linux
432 allocates outrageous amounts of VM (not so bad unless you
433 use mlockall...), which severely limits the number of threads
434 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
435 and 4096 * sizeof (long) (usually this is 16..64k).
436
4372.6 Sun Mar 30 08:28:11 CEST 2008
438 - added aio_sync.
439 - added aio_pathsync.
440 - fix prototypes of (void) functions.
441
4422.51 Sat Oct 6 16:04:54 CEST 2007
443 - perlio isn't generally threadsafe, so aio_close could not work reliably.
444 aio_close now tries a safe hack that might not be that asynchronous
445 (see the manpage for details).
446 - discard callback return values as to not grow the stack endlessly
447 when poll_cb handles many requests without returning.
448 - minor code cleanups.
449
4502.5 Thu Oct 4 14:49:08 CEST 2007
451 - replaced _fd2fh with faster xs code.
452 - aio_close will now try to do "the right thing" and thus might
453 work sensibly for the very first time.
454
4552.41 Mon Sep 24 21:28:21 CEST 2007
456 - after fork, invest some work to make sure that the poll_fileno
457 stays stable (by dup2'ing the new fd over the old one), to make
458 it easier for programs/libs that don't control their forking
459 behaviour and cannot recreate their watchers.
460
4612.4 Sun Aug 5 18:44:22 CEST 2007
462 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
463 successfully demonstrated that you can block on futimes...).
464 - allow undef as fileoffset for aio_read/write and use read/write(2)
465 internally (useful for sockets or O_APPEND handles).
466 - allow undef for length in aio_write.
467 - negative dataoffsets work as expected now in aio_read/aio_write.
468 - use NV instead of UV for 32 bit perls and file offsets, as NVs
469 have a larger range then.
470 - shared code between BDB and IO::AIO.
471 - aio_busy was completely broken. now fixed.
472 - readahead emulation now returns something.
473 - correctly set errno to ENOSYS on unimplemented functions
474 (should never happen, though).
475 - large changes to make it partially compile and run on win32,
476 but win32 lacks too much functionality, and perl overrides way
477 too many functions with crashing versions.
478
4792.33 Tue Jan 23 23:55:41 CET 2007
480 - fix install path (Andreas J. Koenig).
481
4822.32 Mon Jan 22 16:56:23 CET 2007
483 - added aio_rmtree.
484 - wow, aio_mkdir was missing.
485 - aio_load did return undef on error, not -1.
486 - use prefixexp not prefix in autoconf.pm
487 (suggested by ... rt.cpan.org unreachable).
488 - avoid installing autoconf.pm.
489
4902.31 Sat Jan 6 03:46:02 CET 2007
491 - added aio_load.
492
4932.3 Sat Dec 23 05:48:07 CET 2006
494 - fix off-by-one bug in aio_read, causing memory corruption
495 or crashes.
496
4972.21 Fri Dec 22 05:03:38 CET 2006
498 - minor doc updates.
499 - minor cleanups.
500 - IO::AIO::poll returns request count.
501 - undocumented and unfinished async-signal-reporting.
502
5032.2 Tue Oct 31 00:31:00 CET 2006
504 - minor doc updates.
505 - added aio_readlink.
506 - properly zero-terminate aio_read buffer.
507 - fix aio_read/write with nonzero dataoffset.
508 - reduced size of aio request structure.
509 - better diagnostics when pathnames etc. are not byte-encoded;
510 do not leak request in that case, either.
511
5122.1 Sun Oct 29 02:01:57 CET 2006
513 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
514 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
515 - fix a bug in aio_move where it would fail everytime
516 it would have to copy files manually.
517 - doc updates.
518 - start threads only on (very low) demand.
519 - end superfluous threads automatically after 10s idling.
520 - add IO::AIO::max_idle to control this.
521 - some tuning applied to random places.
522 - add aio_mknod.
523
5242.0 Thu Oct 26 18:27:58 CEST 2006
525 - minor incompatibility: max_outstanding semantics have changed.
526 - major rewrite, consider all functionality EXPERIMENTAL.
527 - aio requests can be cancelled.
528 - callbacks can be (re-)set later.
529 - aio requests can choose between 9 priorities.
530 - add aio_group: aio requests can be grouped
531 into composite requests.
532 - generator interface for groups.
533 - add IO::AIO::poll_some.
534 - major documentation improvements.
535 - very minor bugfixes.
536 - add aio_nop for dummy requests.
537 - add aio_busy mainly for benchmarking and debugging.
538 - use "fast" mutexes on linux.
539 - use dynamic (and larger) buffers instead of
540 putting them onto the stack.
541 - optimise x86 and amd64 a bit.
542 - better error checking when ENOMEM.
543 - hopefully fix mem and dirp leaks on fork.
544 - warn about broken perl malloc.
545 - compiles on cygwin (but pread is broken on cygwin
546 which is not detected by autoconf, so you have to
547 edit autoconf/config.h yourself to enable emulation).
548
5491.8 Sat Jun 24 22:20:44 CEST 2006
550 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
551
5521.73 Wed Mar 1 22:49:32 CET 2006
553 - codename "jost"
554 - AIX/Solaris(?) aren't being helpful again, hardcode a value
555 for NAME_MAX and drive with your eyes closed (reported by
556 wcooley@nakedape.cc).
557
5581.72 Thu Feb 2 00:40:44 CET 2006
559 - another minor bug in aio_scandir, again, the callback was called
560 twice when the directory can't be stat'ed.
561
5621.71 Mon Dec 26 20:20:03 CET 2005
563 - grr, another minor bug in aio_scandir, this time resulting
564 in a runtime error.
565
5661.7 Mon Dec 26 19:29:48 CET 2005
567 - aio_scandir errornously called callback twice in some cases.
568 - added AnyEvent example.
569
5701.61 Wed Sep 7 19:40:42 CEST 2005
571 - no longer include $Config{libs}, as distros include too much
572 garbage in there that is not installed on typical systems
573 (for example, debian links perl against -lgdbm and many more
574 libraries despite perl not needing it, slowing down startup and
575 wasting memory).
576
5771.6 Tue Aug 30 17:44:44 CEST 2005
578 - added aio_readdir, aio_scandir.
579 - added aio_sendfile, including sendfile emulation when sendfile
580 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
581 support is unavailable on my solaris 8 machine, but preliminary
582 code is there. What's lacking is configury stuff and testing...).
583
5841.5 Sat Aug 20 02:32:19 CEST 2005
585 - create the aio threads on demand only (good after forking).
586 - somebody nagged about C89 compatibility, so this release should
587 be C89 compatible, but no guarantees for future ones.
588 - abort when the configure script fails.
589
5901.4 Wed Aug 17 08:07:27 CEST 2005
591 - forgot to recreate the pipe after forking, this could cause
592 deadlocks.
593
5941.3 Wed Aug 17 07:25:54 CEST 2005
595 - properly propagate exceptions from callbacks, instead of silently
596 eating them.
597 - use a different fork algorithm that avoids recursive callback
598 invocations and reduces fork latency in busy processes.
599 - fix a bug where the buffer scalar in aio_read got assigned the wrong
600 length after reading.
601 - fix a bug where the child would process some outstanding requests
602 from the parent.
603 - make a copy of the callback scalar, to avoid some very uncommon
604 (but valid) usages where the callback scalar changes.
605 - the callback was never freed in aio_read/aio_write.
606 - aio_read/aio_write will now set the readonly flag on the data
607 scalar for better error reporting.
608
6091.2 Wed Aug 17 01:22:58 CEST 2005
610 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
611 - use SvPVbyte for filenames now. You *need* to encode your strings to
612 the external filename encoding first.
613 - fix the bug where filehandles could leak (again).
614 - clarify freebsd situation: make it work and tell me how, or go away
615 with your underdocumented, broken and outdated OS.
616 - fork'ing should now be officially supported (where linux and
617 posix contradict each other, I followed posix).
618 - only call read() once per poll, not twice (speedup).
619 - new functions: aio_rmdir, aio_symlink.
620 - force callback arguments to be undef or a reference, for better
621 error catching.
622
6231.1 Sun Aug 7 05:27:23 CEST 2005
624 - added configure script to detect availability of some calls.
625 (imperfect, as we cannot detect things like -lrt due to missing
626 feedback yet).
627 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
628 and readahead via manual reading on platforms lacking those.
629 - ported t/03_errors.t+framework by Brad Fitzpatrick
630 from Linux::AIO.
631 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
632 compile with it enabled. Probably breaks others. Oh well.
633 - try to be more careful with errno on non-threaded perls.
634 - cygwins perl insisted on a matching open mode when morphing
635 the fd to an fh.
636 - convert sv's to "byte" encoding in aio_read/aio_write. Might
637 do that for pathnames, too, in the future, so make sure you
638 properly encode your pathnames.
639
6401.0 Fri Jul 22 10:43:30 CEST 2005
641 - aio_open did not reliably deliver (open) filehandles.
642 - all aio_*-functions keep a reference to the filehandle so
643 it doesn't go away while the aio requests is working on it.
644 - disable warnings in AIO.pm.
645
6460.9 Wed Jul 20 23:55:04 CEST 2005
647 - allow recursive calls to poll_cb, use less locking calls, too.
648 - fix the Gtk2-example in the SYNOPSIS.
649 - use pread/pwrite not pread64/pwrite64. this was simply a leftover
650 from Linux::AIO.
651 (found by compiling on cygwin. Unfortunately, cygwin declares but
652 does not implement pread/pwrite).
653 - only include <sys/syscall.h> on linux.
654
6550.5 Tue Jul 12 13:03:09 CEST 2005
656 - removed #include <endian.h>, it's not portable, and we don't
657 need it anyway.
658 - link against -lrt, as it might contain goodies such as fdatasync,
659 and often aio_read, which we do not use yet, but it shouldn't hurt.
660
6610.4 Mon Jul 11 05:28:25 CEST 2005
662 - added IO::AIO::flush, IO::AIO::poll.
663 - make callback argument optional for all calls.
664
6650.3 Mon Jul 11 01:42:37 CEST 2005
666 - restructured manpage.
667 - added SYNOPSIS with examples for Event, Glib, Tk.
668 - remove explicit context support so I don't have to maintain
669 it for threaded perls (i.e. it should work now :).
670
6710.2 Sun Jul 10 22:57:12 CEST 2005
4 - return immediately from poll_wait if nreqs==0. 672 - return immediately from poll_wait if nreqs==0.
5 - get rid of the request pipe and use faster thread-thread 673 - get rid of the request pipe and use faster thread-thread
6 communications. 674 communications for most requests and responses.
7 675
80.1 6760.1
9 - cloned from Linux::AIO, which is very similar. 677 - cloned from Linux::AIO, which is very similar.
