46
474.34 Sun May 1 19:18:24 CEST 2016
48 - def0.h was not properly generated during previous release, causing
49 compile errors on various platforms.
50 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
51 - removed duplicate definition of MAP_HUGETLB, that was found due to
52 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
53 - added (untested!) aio_fcntl, aio_ioctl requests.
54 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
55 as manpages-dev originally claimed.
56
574.33 Mon Jan 18 12:50:10 CET 2016
58 - add IO::AIO::pipe2 function.
59 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
60 constants.
61 - added support for O_TMPFILE and O_PATH constants.
62 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK

744.31 Tue Jun 3 03:29:27 CEST 2014
75 - work around more 5.20 bugs. backwards compatibility my ass.
76
774.3 Fri Apr 11 06:22:38 CEST 2014
78 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
79 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
80 in 5.18. What's so attractive about giving a shit about backwards
81 compatibility - I will never understand.
82
834.2 Sat Jan 25 01:13:14 CET 2014
84 - aio_group could corrupt memory because it didn't restore
85 the stack after req_submit.

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

102 - rename aio_fallocate to aio_allocate, to match documentation.
103 - add list of linux fsid values to aio_statvfs docs.
104 - work around a bug in btrfs' FIEMAP ioctl implementation.
105 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
106 as per unix spec.
107
1084.16 Tue Aug 14 05:39:03 CEST 2012
109 - aio_statvfs was wromgly marked for wd emulation, causing
110 it to malfunction for paths.
111 - fix a crash in aio_fiemap, when used on ranges without any
112 extents.
113 - work around linux kernel bug (at least in 3.2): kernel might
114 trash fiemap input arguments.
115 - work around linux kernel bug (at least in 3.2): kernel does not
116 set FIEMAP_EXTENT_LAST on last segment.
117 - work around linux kernel bug (at least in 3.2): kernel silently
118 truncates segment count if a file.
119 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
120 to quick overview.
121 - splice can corrupt data.
122 - (libeio) remove pread/pwrite emulation.
123 - do not grow mmaped scalars in aio_read.
124 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
125 - provide pread/pwrite for win32, making it link again on native win32.
126
1274.15 Tue Apr 10 06:59:00 CEST 2012
128 - always include linux/types.h for fiemap, for compatibility to
129 ancient systems (Paul Howarth).
130 - experimental support for IO::AIO::splice and ::tee (no aio_...).
131 - provide SEEK_HOLE and SEEK_DATA, if available.
132 - work around (again!) an immensely stupid bug in RHEL, defining
133 autoconf macros in linux system headers (analysed by Paul Howarth).
134
1354.14 Sat Apr 7 02:45:18 CEST 2012
136 - fix stat structure usage on windows, which caused bogus stat results.
137 - (libeio) make readahead emulation behave more like actual readahead by never failing.
138 - new request aio_seek.
139 - new request aio_fiemap.
140 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
141
1424.12 Fri Dec 30 08:51:25 CET 2011
143 - realpath would return a random value if the name was too long,
144 instead of -1.
145 - port to c89.
146
1474.11 Mon Oct 10 00:24:11 CEST 2011
148 - libeio didn't compile on !linux (Paul Howarth).
149
1504.1 Sun Oct 9 10:24:11 CEST 2011
151 - IO::AIO did access uninitialised memory on unsuccessful stats.
152 - (libeio) added syncfs syscall wrapper.
153 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
154 - (libeio) support multiple indepenent working directories.
155 - applied speling corrections by Nicholas Bamber.
156 - tune treescan #threads and #outstanding requests a bit.
157 - reduce the number of file descriptors in use at any one time
158 in treescan, to avoid running out of them (and using too much ram).
159 - take advantage of working directoriy abstractions
160 in aio_scandir and treescan.
161 - reduce compiled size by ~10% by not inlining some key functionality.
162 - added --progress switch to treescan.
163
1644.0 Mon Jul 18 05:01:10 CEST 2011
165 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
166 see FORK BEHAVIOUR in manpage for details.
167 - passes testsuite on win32 now and may actually work
168 (activestate 5.10.1 / MSVC6, YMMV).
169 - (libeio) fix a deadlock where a wakeup signal could be missed when
170 a timeout occured at the same time.
171 - (libeio) added realpath.
172 - (libeio) added fallocate.
173 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
174 - (libeio) do not acquire any locks when forking.
175 - (libeio) use fewer time() syscalls when waiting for new requests.
176
1773.93 Wed Jun 29 23:44:18 CEST 2011
178 - ECB.H WAS MISSING.
179
1803.92 Wed Jun 29 14:45:41 CEST 2011
181 - ecb.h was missing.
182
1833.91 Wed Jun 29 13:24:42 CEST 2011
184 - (libeio) work around a Linux (and likely FreeBSD and other
185 kernels) bug where sendfile would not transfer all the requested
186 bytes on large transfers, using a heuristic.
187 - buggy sendfile caused aio_move/copy to sometimes fail for big
188 files (fortunately it checks that the whole file has been
189 transferred...)
190 - use libecb for higher performance and higher portability.
191 - (libeio) disable sendfile on darwin, it's too broken.
192 - disable fork tests on !linux, as only linux supports mixing
193 pthread and fork in perl.
194 - document the fact that fork doesn't work anymore when using
195 this module, on anything !GNU/Linux.
196 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
197 run on a 0.1MHz cpu. Or so.
198
1993.9 Fri May 27 02:43:47 CEST 2011
200 - (libeio) fix memory corruption in aio_readdirx for the flags
201 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
202 - add lots of newer POSIX and GNU/Linux-specific open
203 flags.
204
2053.8 Sun Mar 27 12:25:33 CEST 2011
206 - use nonstandard but maybe-working-on-bsd fork technique.
207 - support a max_idle value of 0.
208 - support setting of idle timeout value (IO::AIO::idle_timeout).
209
2103.72 Fri Feb 11 04:25:38 CET 2011
211 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
212 - aio_mknod always used a dev_t value of 0.
213 - new treescan option: --grep.
214 - add more S_IF macros, and major/minor/makedev "macros".
215
2163.71 Thu Dec 30 08:18:46 CET 2010
217 - the numerical result value passed to callbacks did not stringify
218 correctly, due to internal reuse and failure to reset the sv flags.
219 - actually test for posix_[mf]advise, as at least uClibc defines
220 _POSIX_ADVISORY_INFO without actually having any of the required
221 funcitonality. ugh.
222
2233.7 Mon Nov 1 23:00:34 CET 2010
224 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
225 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
226 - document the sad state of affairs w.r.t. pthread on many bsds.
227 - do not enable mmap on systems without _POSIX_MAPPED_FILES
228 (openbsd 4.8).
229 - do not leak memory in IO::AIO::mmap when the scalar already
230 had string-data.
231 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
232 them.
233 - cache the result IV, for a minor speedup in the common case.
234 - croak when an mmapped-scalar changes location, to detect
235 user-errors better.
236 - fix aio_readlink prototype.
237
2383.65 Wed Mar 31 02:45:05 CEST 2010
239 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
240 cut off long pathnames in aio_readlink (based on patch by
241 Rasmus Andersson).
242 - a double fork partially killed the event pipe (great testcase
243 by dormando). affects IO::AIO, BDB and Async::Interrupt.
244 - suck steve's dick and rename our symbols to avoid colliding
245 with nonstandard identifier spam on the broken os x pseudo-os.
246 affects IO::AIO and BDB.
247
2483.6 Mon Jan 11 00:43:39 CET 2010
249 - (libeio) more fixes for the freebsd/apple sendfile - broken by
250 manpage standards, but apparently correct accoridng to actual
251 kernel sources.
252 - add IO::AIO::mmap/munmap support.
253 - add IO::AIO::m(un)lockall support.
254 - clean up manpage.
255
2563.5 Thu Jan 7 21:25:04 CET 2010
257 - (liebio) fix freebsd sendfile (Vanilla Hsu).
258 - (libeio) also fix darwin sendfile that suffered from a similar bug.
259 - add aio_statvfs as interface to statvfs/fstatvfs.
260 - work around buggy symlink() on cygwin in the testsuite.
261 - wtf. freebsd-8.0 actually passes the testsuite! I knew
262 they could implement fork and semaphores one day! cheers!
263
2643.4 Sat Jan 2 15:13:04 CET 2010
265 - (libeio) max_poll_time was not properly converted to ticks.
266 - clarify cancel_subs description.
267 - IO::AIO::sendfile did not actually return the return value
268 from the sendfile call.
269 - implement aio_msync, aio_mtouch.
270 - (libeio) tentatively support darwin in sendfile.
271
2723.31 Thu Nov 12 02:14:29 CET 2009
273 - fix result status documentation of aio_copy, aio_move.
274 - speed up object creation considerably by avoiding
275 hash lookups.
276
2773.3 Wed Aug 5 13:52:58 CEST 2009
278 - use common::sense.
279 - use common schmorp.h header.
280 - allow integers (file descriptors) in addition to file handles.
281 - take advantage of linux' eventfd (but it seems slower on smp?).
282 - use poll not select on posix platforms.
283
2843.261 Wed Jul 1 10:11:51 CEST 2009
285 - more 0S X workarounds (patch by Tokuhiro Matsuno).
286
2873.26 Tue Jun 30 09:33:26 CEST 2009
288 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
289 try to work around this horribly broken OS in a somewhat hackish
290 way. might help other os's too.
291
2923.25 Sat Jun 27 05:18:26 CEST 2009
293 - added IO::AIO::fadvise and IO::AIO::sendfile.
294 - (libeio) replaced quicksort+insertion sort by a tuned radix
295 sort + insertion sort, resulting in comparable runtime (usually
296 faster) to the old version, but without any ill side effects on
297 degenerated (for quicksort) data.
298 - (libeio) correctly sort dirs by inodes if we have perfect type
299 knowledge and DIRS_FIRST is used.
300 - (libeio) internally the wrong DT_* constants were used, but no
301 known system has differing EIO_DT_*/DT_* values, so not an issue.
302 - removed a (harmless) assert that was left over on the code
303 but should not have been.
304 - use more correct types (change IO length from IV to VAL64,
305 which makes a difference on systems without 64 bit perls).
306
3073.23 Sat Jun 13 16:57:58 CEST 2009
308 - fix off-by-one bug in aio_readdir that was introduced in the
309 rushed 3.22 release.
310
3113.22 Sat Jun 13 15:32:40 CEST 2009
312 - speed up readdirx sort algorithm slightly.
313 - bin/treescan was missing from distro tarball.
314
3153.21 Fri Jun 12 18:45:53 CEST 2009
316 - new options --dirs and --files for treescan.
317 - install bin/treescan by default.
318 - (libeio) aio_readdir can now be cancelled while executing.
319 - fix a printf format string for 64 bit systems (could lead
320 to problems on big endian 64 bit systems).
321 - do not use qsort() but our own algorithm: glibc initialises
322 the whole locale and I/O subsystem inside qsort, causing
323 a stack overflow on 32 bit machines. The new sort uses much less
324 stack and is more than twice as fast in typical situations.
325
3263.2 Sun Jun 7 20:30:05 CEST 2009
327 - (libeio) pwrite emulation was even more flawed than intended and did
328 not restore the file offset.
329 - add aio_readdirx, which can return inode and filetype and sort
330 the names in various ways.
331 - unfortunately, utime, chmod, chown on an open file that has just
332 been written can easily block, which caused aio_copy to block the
333 process. no more!
334 - no longer rely on dst path in aio_copy when futime is available.
335
3363.19 Tue Apr 21 22:05:21 CEST 2009
337 - more perl 5.10 workarounds for aio_read and write.
338 - aio_write no longer modifies the sv (if possible).
339 - aio_read now works correctly with magic values.
340
3413.18 Sun Apr 19 21:17:32 CEST 2009
342 - better diagnostics when some aio_* functions get passed an illegal fh.
343 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
344
3453.17 Thu Nov 20 08:45:36 CET 2008
346 - (libeio) added aio_sync_file_range (untested).
347 - add aio_busy to @IO::AIO::AIO_REQ.
348
3493.16 Wed Oct 22 18:28:01 CEST 2008
350 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
351 part to improve portability to perl 5.8 (reported by szymon).
352
3533.15 Mon Oct 13 00:39:55 CEST 2008
354 - automatic removal of feeders was broken.
355 - (libeio) use a more robust method to detect whether a feeder
356 has added something to the group or not.
357
3583.1 Thu Oct 2 13:34:40 CEST 2008
359 - pre-deref the passed callback object, for increased speed
360 and decreased memory usage.
361 - call on_next_submit callback even for aio_group - impact unknown,
362 but seems more correct.
363 - $req->cb now returns the original callback.
364 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
365 requiring a thread switch.
366 - (libeio) status code of aio_futime and aio_utime was always passed 0.
367 - do some other ยต-optimisations.
368
3693.07 Sat Aug 2 16:06:13 CEST 2008
370 - do not include LIBS in autoconf tests.
371
3723.06 Tue Jul 15 12:41:32 CEST 2008
373 - move preadwritelock definition before it's first reference,
374 to make it compile again on broken platforms (they still exist)
375 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
376
3773.05 Thu Jun 19 23:23:52 CEST 2008
378 - work around perl overriding readdir etc. with thread-unsafe
379 (sic!) versions.
380
3813.04 Wed Jun 18 01:35:38 CEST 2008
382 - (libeio) fix eio_mknod, which confused it's arguments.
383 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
384 is stupid.
385 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
386 - (libeio) fix a bug that could potentially cause IO::AIO
387 not to get initialised properly.
388
3893.03 Thu May 29 05:33:30 CEST 2008
390 - (libeio) correctly call pthread_attr_destroy ().
391 - (libeio) work around broken bsd headers once more.
392 - reduce shared library size again by not including wrappers.
393 - max_outstanding could cause poll to enter a busy-waiting loop.
394 - document the new IO::AIO::poll_cb result value.
395
3963.02 Mon May 12 02:32:02 CEST 2008
397 - fix a memory leak on aio_readlink.
398 - bring back working fchmod.
399 - nop and busy now set result to 0.
400 - set errno to ENOMEM when allocation fails.
401
4023.01 Sun May 11 03:07:03 CEST 2008
403 - (libeio) make it compile on systems without readahead or readdir_r.
404 - (libeio) improve configure check for readahead availability.
405 - do not try to link against -lrt.
406 - use a separate configure script for IO::AIO (not the libeio one).
407
4083.0 Sun May 11 00:57:14 CEST 2008
409 - added bin/treescan to the distribution.
410 - switched to using libeio.
411 - LOTS OF INCOMPATIBLE CHANGES:
412 - remove signal functionality, it is not worth the effort.
413 - max_outstanding no longer returns the previous number of requests.
414 - poll_cb no longer returns number of requests.

4162.62 Sat Apr 26 13:59:33 CEST 2008
417 - port to solaris perls configured for old posix
418 (analysed by Jost Krieger).
419 - keep a reference to the perl filehandle object in aio_close,
420 so it doesn't get closed prematurely, leading to ugly races.
421
4222.61 Wed Apr 16 18:45:02 CEST 2008
423 - fix treescan output duplication and improve output ordering.
424 also display files given on the commandline.
425 - use a different algorithm for aio_close that is faster
426 and probably has even lower chances of blocking.
427 - do our own stack memory management for threads - linux
428 allocates outrageous amounts of VM (not so bad unless you
429 use mlockall...), which severely limits the number of threads
430 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
431 and 4096 * sizeof (long) (usually this is 16..64k).
432
4332.6 Sun Mar 30 08:28:11 CEST 2008
434 - added aio_sync.
435 - added aio_pathsync.
436 - fix prototypes of (void) functions.
437
4382.51 Sat Oct 6 16:04:54 CEST 2007
439 - perlio isn't generally threadsafe, so aio_close could not work reliably.
440 aio_close now tries a safe hack that might not be that asynchronous
441 (see the manpage for details).
442 - discard callback return values as to not grow the stack endlessly
443 when poll_cb handles many requests without returning.
444 - minor code cleanups.
445
4462.5 Thu Oct 4 14:49:08 CEST 2007
447 - replaced _fd2fh with faster xs code.
448 - aio_close will now try to do "the right thing" and thus might
449 work sensibly for the very first time.
450
4512.41 Mon Sep 24 21:28:21 CEST 2007
452 - after fork, invest some work to make sure that the poll_fileno
453 stays stable (by dup2'ing the new fd over the old one), to make
454 it easier for programs/libs that don't control their forking
455 behaviour and cannot recreate their watchers.
456
4572.4 Sun Aug 5 18:44:22 CEST 2007
458 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
459 successfully demonstrated that you can block on futimes...).
460 - allow undef as fileoffset for aio_read/write and use read/write(2)
461 internally (useful for sockets or O_APPEND handles).
462 - allow undef for length in aio_write.
463 - negative dataoffsets work as expected now in aio_read/aio_write.
464 - use NV instead of UV for 32 bit perls and file offsets, as NVs
465 have a larger range then.
466 - shared code between BDB and IO::AIO.
467 - aio_busy was completely broken. now fixed.
468 - readahead emulation now returns something.
469 - correctly set errno to ENOSYS on unimplemented functions
470 (should never happen, though).
471 - large changes to make it partially compile and run on win32,
472 but win32 lacks too much functionality, and perl overrides way
473 too many functions with crashing versions.
474
4752.33 Tue Jan 23 23:55:41 CET 2007
476 - fix install path (Andreas J. Koenig).
477
4782.32 Mon Jan 22 16:56:23 CET 2007
479 - added aio_rmtree.
480 - wow, aio_mkdir was missing.
481 - aio_load did return undef on error, not -1.
482 - use prefixexp not prefix in autoconf.pm
483 (suggested by ... rt.cpan.org unreachable).
484 - avoid installing autoconf.pm.
485
4862.31 Sat Jan 6 03:46:02 CET 2007
487 - added aio_load.
488
4892.3 Sat Dec 23 05:48:07 CET 2006
490 - fix off-by-one bug in aio_read, causing memory corruption
491 or crashes.
492
4932.21 Fri Dec 22 05:03:38 CET 2006
494 - minor doc updates.
495 - minor cleanups.
496 - IO::AIO::poll returns request count.
497 - undocumented and unfinished async-signal-reporting.
498
4992.2 Tue Oct 31 00:31:00 CET 2006
500 - minor doc updates.
501 - added aio_readlink.
502 - properly zero-terminate aio_read buffer.
503 - fix aio_read/write with nonzero dataoffset.
504 - reduced size of aio request structure.
505 - better diagnostics when pathnames etc. are not byte-encoded;
506 do not leak request in that case, either.
507
5082.1 Sun Oct 29 02:01:57 CET 2006
509 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
510 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
511 - fix a bug in aio_move where it would fail everytime
512 it would have to copy files manually.
513 - doc updates.
514 - start threads only on (very low) demand.
515 - end superfluous threads automatically after 10s idling.
516 - add IO::AIO::max_idle to control this.
517 - some tuning applied to random places.
518 - add aio_mknod.
519
5202.0 Thu Oct 26 18:27:58 CEST 2006
521 - minor incompatibility: max_outstanding semantics have changed.
522 - major rewrite, consider all functionality EXPERIMENTAL.
523 - aio requests can be cancelled.
524 - callbacks can be (re-)set later.
525 - aio requests can choose between 9 priorities.
526 - add aio_group: aio requests can be grouped
527 into composite requests.
528 - generator interface for groups.
529 - add IO::AIO::poll_some.
530 - major documentation improvements.
531 - very minor bugfixes.
532 - add aio_nop for dummy requests.
533 - add aio_busy mainly for benchmarking and debugging.
534 - use "fast" mutexes on linux.
535 - use dynamic (and larger) buffers instead of
536 putting them onto the stack.
537 - optimise x86 and amd64 a bit.
538 - better error checking when ENOMEM.
539 - hopefully fix mem and dirp leaks on fork.
540 - warn about broken perl malloc.
541 - compiles on cygwin (but pread is broken on cygwin
542 which is not detected by autoconf, so you have to
543 edit autoconf/config.h yourself to enable emulation).
544
5451.8 Sat Jun 24 22:20:44 CEST 2006
546 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
547
5481.73 Wed Mar 1 22:49:32 CET 2006
549 - codename "jost"
550 - AIX/Solaris(?) aren't being helpful again, hardcode a value
551 for NAME_MAX and drive with your eyes closed (reported by
552 wcooley@nakedape.cc).
553
5541.72 Thu Feb 2 00:40:44 CET 2006
555 - another minor bug in aio_scandir, again, the callback was called
556 twice when the directory can't be stat'ed.
557
5581.71 Mon Dec 26 20:20:03 CET 2005
559 - grr, another minor bug in aio_scandir, this time resulting
560 in a runtime error.
561
5621.7 Mon Dec 26 19:29:48 CET 2005
563 - aio_scandir errornously called callback twice in some cases.
564 - added AnyEvent example.
565
5661.61 Wed Sep 7 19:40:42 CEST 2005
567 - no longer include $Config{libs}, as distros include too much
568 garbage in there that is not installed on typical systems
569 (for example, debian links perl against -lgdbm and many more
570 libraries despite perl not needing it, slowing down startup and
571 wasting memory).
572
5731.6 Tue Aug 30 17:44:44 CEST 2005
574 - added aio_readdir, aio_scandir.
575 - added aio_sendfile, including sendfile emulation when sendfile
576 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
577 support is unavailable on my solaris 8 machine, but preliminary
578 code is there. What's lacking is configury stuff and testing...).
579
5801.5 Sat Aug 20 02:32:19 CEST 2005
581 - create the aio threads on demand only (good after forking).
582 - somebody nagged about C89 compatibility, so this release should
583 be C89 compatible, but no guarantees for future ones.
584 - abort when the configure script fails.
585
5861.4 Wed Aug 17 08:07:27 CEST 2005
587 - forgot to recreate the pipe after forking, this could cause
588 deadlocks.
589
5901.3 Wed Aug 17 07:25:54 CEST 2005
591 - properly propagate exceptions from callbacks, instead of silently
592 eating them.
593 - use a different fork algorithm that avoids recursive callback
594 invocations and reduces fork latency in busy processes.
595 - fix a bug where the buffer scalar in aio_read got assigned the wrong
596 length after reading.
597 - fix a bug where the child would process some outstanding requests
598 from the parent.
599 - make a copy of the callback scalar, to avoid some very uncommon
600 (but valid) usages where the callback scalar changes.
601 - the callback was never freed in aio_read/aio_write.
602 - aio_read/aio_write will now set the readonly flag on the data
603 scalar for better error reporting.
604
6051.2 Wed Aug 17 01:22:58 CEST 2005
606 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
607 - use SvPVbyte for filenames now. You *need* to encode your strings to
608 the external filename encoding first.
609 - fix the bug where filehandles could leak (again).
610 - clarify freebsd situation: make it work and tell me how, or go away
611 with your underdocumented, broken and outdated OS.
612 - fork'ing should now be officially supported (where linux and
613 posix contradict each other, I followed posix).
614 - only call read() once per poll, not twice (speedup).
615 - new functions: aio_rmdir, aio_symlink.
616 - force callback arguments to be undef or a reference, for better
617 error catching.
618
6191.1 Sun Aug 7 05:27:23 CEST 2005
3 - added configure script to detetc availability of some calls. 620 - added configure script to detect availability of some calls.
621 (imperfect, as we cannot detect things like -lrt due to missing
622 feedback yet).
623 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
624 and readahead via manual reading on platforms lacking those.
4 - ported t/03_errors.t+framework by Brad Fitzpatrick 625 - ported t/03_errors.t+framework by Brad Fitzpatrick
5 from Linux::AIO. 626 from Linux::AIO.
6 - removed XOPEN_SOURCE because stupid solaris 9 doesn't 627 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
7 compile with it enabled. Probably breaks others. Oh well. 628 compile with it enabled. Probably breaks others. Oh well.
8 - emulate fdatasync by fsync on platforms lacking it. 629 - try to be more careful with errno on non-threaded perls.
630 - cygwins perl insisted on a matching open mode when morphing
631 the fd to an fh.
632 - convert sv's to "byte" encoding in aio_read/aio_write. Might
633 do that for pathnames, too, in the future, so make sure you
634 properly encode your pathnames.
9 635
101.0 Fri Jul 22 10:43:30 CEST 2005 6361.0 Fri Jul 22 10:43:30 CEST 2005
11 - aio_open did not reliably deliver (open) filehandles. 637 - aio_open did not reliably deliver (open) filehandles.
12 - all aio_*-functions keep a reference to the filehandle so 638 - all aio_*-functions keep a reference to the filehandle so
13 it doesn't go away while the aio requests is working on it. 639 it doesn't go away while the aio requests is working on it.
