29
30 4.19 Sun Jan 6 12:47:26 CET 2013
31 - avoid endless loop in fiemap with some XFS files.
32 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
33 and call rename/rmdir instead of renameat/unlinkat.
34
35 4.18 Thu Oct 11 07:01:26 CEST 2012
36 - fix unintended xthread_create by intentionalising it :)
37

40 - add list of linux fsid values to aio_statvfs docs.
41 - work around a bug in btrfs' FIEMAP ioctl implementation.
42 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
43 as per unix spec.
44
45 4.16 Tue Aug 14 05:39:03 CEST 2012
46 - aio_statvfs was wromgly marked for wd emulation, causing
47 it to malfunction for paths.
48 - fix a crash in aio_fiemap, when used on ranges without any
49 extents.
50 - work around linux kernel bug (at least in 3.2): kernel might
51 trash fiemap input arguments.
52 - work around linux kernel bug (at least in 3.2): kernel does not
53 set FIEMAP_EXTENT_LAST on last segment.
54 - work around linux kernel bug (at least in 3.2): kernel silently
55 truncates segment count if a file.
56 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
57 to quick overview.
58 - splice can corrupt data.
59 - (libeio) remove pread/pwrite emulation.
60 - do not grow mmaped scalars in aio_read.
61 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
62 - provide pread/pwrite for win32, making it link again on native win32.
63
64 4.15 Tue Apr 10 06:59:00 CEST 2012
65 - always include linux/types.h for fiemap, for compatibility to
66 ancient systems (Paul Howarth).
67 - experimental support for IO::AIO::splice and ::tee (no aio_...).
68 - provide SEEK_HOLE and SEEK_DATA, if available.
69 - work around (again!) an immensely stupid bug in RHEL, defining
70 autoconf macros in linux system headers (analysed by Paul Howarth).
71
72 4.14 Sat Apr 7 02:45:18 CEST 2012
73 - fix stat structure usage on windows, which caused bogus stat results.
74 - (libeio) make readahead emulation behave more like actual readahead by never failing.
75 - new request aio_seek.
76 - new request aio_fiemap.
77 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
78
79 4.12 Fri Dec 30 08:51:25 CET 2011
80 - realpath would return a random value if the name was too long,
81 instead of -1.
82 - port to c89.
83
84 4.11 Mon Oct 10 00:24:11 CEST 2011
85 - libeio didn't compile on !linux (Paul Howarth).
86
87 4.1 Sun Oct 9 10:24:11 CEST 2011
88 - IO::AIO did access uninitialised memory on unsuccessful stats.
89 - (libeio) added syncfs syscall wrapper.
90 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
91 - (libeio) support multiple indepenent working directories.
92 - applied speling corrections by Nicholas Bamber.
93 - tune treescan #threads and #outstanding requests a bit.
94 - reduce the number of file descriptors in use at any one time
95 in treescan, to avoid running out of them (and using too much ram).
96 - take advantage of working directoriy abstractions
97 in aio_scandir and treescan.
98 - reduce compiled size by ~10% by not inlining some key functionality.
99 - added --progress switch to treescan.
100
101 4.0 Mon Jul 18 05:01:10 CEST 2011
102 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
103 see FORK BEHAVIOUR in manpage for details.
104 - passes testsuite on win32 now and may actually work
105 (activestate 5.10.1 / MSVC6, YMMV).
106 - (libeio) fix a deadlock where a wakeup signal could be missed when
107 a timeout occured at the same time.
108 - (libeio) added realpath.
109 - (libeio) added fallocate.
110 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
111 - (libeio) do not acquire any locks when forking.
112 - (libeio) use fewer time() syscalls when waiting for new requests.
113
114 3.93 Wed Jun 29 23:44:18 CEST 2011
115 - ECB.H WAS MISSING.
116
117 3.92 Wed Jun 29 14:45:41 CEST 2011
118 - ecb.h was missing.
119
120 3.91 Wed Jun 29 13:24:42 CEST 2011
121 - (libeio) work around a Linux (and likely FreeBSD and other
122 kernels) bug where sendfile would not transfer all the requested
123 bytes on large transfers, using a heuristic.
124 - buggy sendfile caused aio_move/copy to sometimes fail for big
125 files (fortunately it checks that the whole file has been
126 transferred...)
127 - use libecb for higher performance and higher portability.
128 - (libeio) disable sendfile on darwin, it's too broken.
129 - disable fork tests on !linux, as only linux supports mixing
130 pthread and fork in perl.
131 - document the fact that fork doesn't work anymore when using
132 this module, on anything !GNU/Linux.
133 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
134 run on a 0.1MHz cpu. Or so.
135
136 3.9 Fri May 27 02:43:47 CEST 2011
137 - (libeio) fix memory corruption in aio_readdirx for the flags
138 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
139 - add lots of newer POSIX and GNU/Linux-specific open
140 flags.
141
142 3.8 Sun Mar 27 12:25:33 CEST 2011
143 - use nonstandard but maybe-working-on-bsd fork technique.
144 - support a max_idle value of 0.
145 - support setting of idle timeout value (IO::AIO::idle_timeout).
146
147 3.72 Fri Feb 11 04:25:38 CET 2011
148 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
149 - aio_mknod always used a dev_t value of 0.
150 - new treescan option: --grep.
151 - add more S_IF macros, and major/minor/makedev "macros".
152
153 3.71 Thu Dec 30 08:18:46 CET 2010
154 - the numerical result value passed to callbacks did not stringify
155 correctly, due to internal reuse and failure to reset the sv flags.
156 - actually test for posix_[mf]advise, as at least uClibc defines
157 _POSIX_ADVISORY_INFO without actually having any of the required
158 funcitonality. ugh.
159
160 3.7 Mon Nov 1 23:00:34 CET 2010
161 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
162 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
163 - document the sad state of affairs w.r.t. pthread on many bsds.
164 - do not enable mmap on systems without _POSIX_MAPPED_FILES
165 (openbsd 4.8).
166 - do not leak memory in IO::AIO::mmap when the scalar already
167 had string-data.
168 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
169 them.
170 - cache the result IV, for a minor speedup in the common case.
171 - croak when an mmapped-scalar changes location, to detect
172 user-errors better.
173 - fix aio_readlink prototype.
174
175 3.65 Wed Mar 31 02:45:05 CEST 2010
176 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
177 cut off long pathnames in aio_readlink (based on patch by
178 Rasmus Andersson).
179 - a double fork partially killed the event pipe (great testcase
180 by dormando). affects IO::AIO, BDB and Async::Interrupt.
181 - suck steve's dick and rename our symbols to avoid colliding
182 with nonstandard identifier spam on the broken os x pseudo-os.
183 affects IO::AIO and BDB.
184
185 3.6 Mon Jan 11 00:43:39 CET 2010
186 - (libeio) more fixes for the freebsd/apple sendfile - broken by
187 manpage standards, but apparently correct accoridng to actual
188 kernel sources.
189 - add IO::AIO::mmap/munmap support.
190 - add IO::AIO::m(un)lockall support.
191 - clean up manpage.
192
193 3.5 Thu Jan 7 21:25:04 CET 2010
194 - (liebio) fix freebsd sendfile (Vanilla Hsu).
195 - (libeio) also fix darwin sendfile that suffered from a similar bug.
196 - add aio_statvfs as interface to statvfs/fstatvfs.
197 - work around buggy symlink() on cygwin in the testsuite.
198 - wtf. freebsd-8.0 actually passes the testsuite! I knew
199 they could implement fork and semaphores one day! cheers!
200
201 3.4 Sat Jan 2 15:13:04 CET 2010
202 - (libeio) max_poll_time was not properly converted to ticks.
203 - clarify cancel_subs description.
204 - IO::AIO::sendfile did not actually return the return value
205 from the sendfile call.
206 - implement aio_msync, aio_mtouch.
207 - (libeio) tentatively support darwin in sendfile.
208
209 3.31 Thu Nov 12 02:14:29 CET 2009
210 - fix result status documentation of aio_copy, aio_move.
211 - speed up object creation considerably by avoiding
212 hash lookups.
213
214 3.3 Wed Aug 5 13:52:58 CEST 2009
215 - use common::sense.
216 - use common schmorp.h header.
217 - allow integers (file descriptors) in addition to file handles.
218 - take advantage of linux' eventfd (but it seems slower on smp?).
219 - use poll not select on posix platforms.
220
221 3.261 Wed Jul 1 10:11:51 CEST 2009
222 - more 0S X workarounds (patch by Tokuhiro Matsuno).
223
224 3.26 Tue Jun 30 09:33:26 CEST 2009
225 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
226 try to work around this horribly broken OS in a somewhat hackish
227 way. might help other os's too.
228
229 3.25 Sat Jun 27 05:18:26 CEST 2009
230 - added IO::AIO::fadvise and IO::AIO::sendfile.
231 - (libeio) replaced quicksort+insertion sort by a tuned radix
232 sort + insertion sort, resulting in comparable runtime (usually
233 faster) to the old version, but without any ill side effects on
234 degenerated (for quicksort) data.
235 - (libeio) correctly sort dirs by inodes if we have perfect type
236 knowledge and DIRS_FIRST is used.
237 - (libeio) internally the wrong DT_* constants were used, but no
238 known system has differing EIO_DT_*/DT_* values, so not an issue.
239 - removed a (harmless) assert that was left over on the code
240 but should not have been.
241 - use more correct types (change IO length from IV to VAL64,
242 which makes a difference on systems without 64 bit perls).
243
244 3.23 Sat Jun 13 16:57:58 CEST 2009
245 - fix off-by-one bug in aio_readdir that was introduced in the
246 rushed 3.22 release.
247
248 3.22 Sat Jun 13 15:32:40 CEST 2009
249 - speed up readdirx sort algorithm slightly.
250 - bin/treescan was missing from distro tarball.
251
252 3.21 Fri Jun 12 18:45:53 CEST 2009
253 - new options --dirs and --files for treescan.
254 - install bin/treescan by default.
255 - (libeio) aio_readdir can now be cancelled while executing.
256 - fix a printf format string for 64 bit systems (could lead
257 to problems on big endian 64 bit systems).
258 - do not use qsort() but our own algorithm: glibc initialises
259 the whole locale and I/O subsystem inside qsort, causing
260 a stack overflow on 32 bit machines. The new sort uses much less
261 stack and is more than twice as fast in typical situations.
262
263 3.2 Sun Jun 7 20:30:05 CEST 2009
264 - (libeio) pwrite emulation was even more flawed than intended and did
265 not restore the file offset.
266 - add aio_readdirx, which can return inode and filetype and sort
267 the names in various ways.
268 - unfortunately, utime, chmod, chown on an open file that has just
269 been written can easily block, which caused aio_copy to block the
270 process. no more!
271 - no longer rely on dst path in aio_copy when futime is available.
272
273 3.19 Tue Apr 21 22:05:21 CEST 2009
274 - more perl 5.10 workarounds for aio_read and write.
275 - aio_write no longer modifies the sv (if possible).
276 - aio_read now works correctly with magic values.
277
278 3.18 Sun Apr 19 21:17:32 CEST 2009
279 - better diagnostics when some aio_* functions get passed an illegal fh.
280 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
281
282 3.17 Thu Nov 20 08:45:36 CET 2008
283 - (libeio) added aio_sync_file_range (untested).
284 - add aio_busy to @IO::AIO::AIO_REQ.
285
286 3.16 Wed Oct 22 18:28:01 CEST 2008
287 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
288 part to improve portability to perl 5.8 (reported by szymon).
289
290 3.15 Mon Oct 13 00:39:55 CEST 2008
291 - automatic removal of feeders was broken.
292 - (libeio) use a more robust method to detect whether a feeder
293 has added something to the group or not.
294
295 3.1 Thu Oct 2 13:34:40 CEST 2008
296 - pre-deref the passed callback object, for increased speed
297 and decreased memory usage.
298 - call on_next_submit callback even for aio_group - impact unknown,
299 but seems more correct.
300 - $req->cb now returns the original callback.
301 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
302 requiring a thread switch.
303 - (libeio) status code of aio_futime and aio_utime was always passed 0.
304 - do some other µ-optimisations.
305
306 3.07 Sat Aug 2 16:06:13 CEST 2008
307 - do not include LIBS in autoconf tests.
308
309 3.06 Tue Jul 15 12:41:32 CEST 2008
310 - move preadwritelock definition before it's first reference,
311 to make it compile again on broken platforms (they still exist)
312 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
313
314 3.05 Thu Jun 19 23:23:52 CEST 2008
315 - work around perl overriding readdir etc. with thread-unsafe
316 (sic!) versions.
317
318 3.04 Wed Jun 18 01:35:38 CEST 2008
319 - (libeio) fix eio_mknod, which confused it's arguments.
320 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
321 is stupid.
322 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
323 - (libeio) fix a bug that could potentially cause IO::AIO
324 not to get initialised properly.
325
326 3.03 Thu May 29 05:33:30 CEST 2008
327 - (libeio) correctly call pthread_attr_destroy ().
328 - (libeio) work around broken bsd headers once more.
329 - reduce shared library size again by not including wrappers.
330 - max_outstanding could cause poll to enter a busy-waiting loop.
331 - document the new IO::AIO::poll_cb result value.
332
333 3.02 Mon May 12 02:32:02 CEST 2008
334 - fix a memory leak on aio_readlink.
335 - bring back working fchmod.
336 - nop and busy now set result to 0.
337 - set errno to ENOMEM when allocation fails.
338
339 3.01 Sun May 11 03:07:03 CEST 2008
340 - (libeio) make it compile on systems without readahead or readdir_r.
341 - (libeio) improve configure check for readahead availability.
342 - do not try to link against -lrt.
343 - use a separate configure script for IO::AIO (not the libeio one).
344
345 3.0 Sun May 11 00:57:14 CEST 2008
346 - added bin/treescan to the distribution.
347 - switched to using libeio.
348 - LOTS OF INCOMPATIBLE CHANGES:
349 - remove signal functionality, it is not worth the effort.
350 - max_outstanding no longer returns the previous number of requests.
351 - poll_cb no longer returns number of requests.
352
353 2.62 Sat Apr 26 13:59:33 CEST 2008
354 - port to solaris perls configured for old posix
355 (analysed by Jost Krieger).
356 - keep a reference to the perl filehandle object in aio_close,
357 so it doesn't get closed prematurely, leading to ugly races.
358
359 2.61 Wed Apr 16 18:45:02 CEST 2008
360 - fix treescan output duplication and improve output ordering.
361 also display files given on the commandline.
362 - use a different algorithm for aio_close that is faster
363 and probably has even lower chances of blocking.
364 - do our own stack memory management for threads - linux
365 allocates outrageous amounts of VM (not so bad unless you
366 use mlockall...), which severely limits the number of threads
367 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
368 and 4096 * sizeof (long) (usually this is 16..64k).
369
370 2.6 Sun Mar 30 08:28:11 CEST 2008
371 - added aio_sync.
372 - added aio_pathsync.
373 - fix prototypes of (void) functions.
374
375 2.51 Sat Oct 6 16:04:54 CEST 2007
376 - perlio isn't generally threadsafe, so aio_close could not work reliably.
377 aio_close now tries a safe hack that might not be that asynchronous
378 (see the manpage for details).
379 - discard callback return values as to not grow the stack endlessly
380 when poll_cb handles many requests without returning.
381 - minor code cleanups.
382
383 2.5 Thu Oct 4 14:49:08 CEST 2007
384 - replaced _fd2fh with faster xs code.
385 - aio_close will now try to do "the right thing" and thus might
386 work sensibly for the very first time.
387
388 2.41 Mon Sep 24 21:28:21 CEST 2007
389 - after fork, invest some work to make sure that the poll_fileno
390 stays stable (by dup2'ing the new fd over the old one), to make
391 it easier for programs/libs that don't control their forking
392 behaviour and cannot recreate their watchers.
393
394 2.4 Sun Aug 5 18:44:22 CEST 2007
395 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
396 successfully demonstrated that you can block on futimes...).
397 - allow undef as fileoffset for aio_read/write and use read/write(2)
398 internally (useful for sockets or O_APPEND handles).
399 - allow undef for length in aio_write.
400 - negative dataoffsets work as expected now in aio_read/aio_write.
401 - use NV instead of UV for 32 bit perls and file offsets, as NVs
402 have a larger range then.
403 - shared code between BDB and IO::AIO.
404 - aio_busy was completely broken. now fixed.
405 - readahead emulation now returns something.
406 - correctly set errno to ENOSYS on unimplemented functions
407 (should never happen, though).
408 - large changes to make it partially compile and run on win32,
409 but win32 lacks too much functionality, and perl overrides way
410 too many functions with crashing versions.
411
412 2.33 Tue Jan 23 23:55:41 CET 2007
413 - fix install path (Andreas J. Koenig).
414
415 2.32 Mon Jan 22 16:56:23 CET 2007
416 - added aio_rmtree.
417 - wow, aio_mkdir was missing.
418 - aio_load did return undef on error, not -1.
419 - use prefixexp not prefix in autoconf.pm
420 (suggested by ... rt.cpan.org unreachable).
421 - avoid installing autoconf.pm.
422
423 2.31 Sat Jan 6 03:46:02 CET 2007
424 - added aio_load.
425
426 2.3 Sat Dec 23 05:48:07 CET 2006
427 - fix off-by-one bug in aio_read, causing memory corruption
428 or crashes.
429
430 2.21 Fri Dec 22 05:03:38 CET 2006
431 - minor doc updates.
432 - minor cleanups.
433 - IO::AIO::poll returns request count.
434 - undocumented and unfinished async-signal-reporting.
435
436 2.2 Tue Oct 31 00:31:00 CET 2006
437 - minor doc updates.
438 - added aio_readlink.
439 - properly zero-terminate aio_read buffer.
440 - fix aio_read/write with nonzero dataoffset.
441 - reduced size of aio request structure.
442 - better diagnostics when pathnames etc. are not byte-encoded;
443 do not leak request in that case, either.
444
445 2.1 Sun Oct 29 02:01:57 CET 2006
446 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
447 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
448 - fix a bug in aio_move where it would fail everytime
449 it would have to copy files manually.
450 - doc updates.
451 - start threads only on (very low) demand.
452 - end superfluous threads automatically after 10s idling.
453 - add IO::AIO::max_idle to control this.
454 - some tuning applied to random places.
455 - add aio_mknod.
456
457 2.0 Thu Oct 26 18:27:58 CEST 2006
458 - minor incompatibility: max_outstanding semantics have changed.
459 - major rewrite, consider all functionality EXPERIMENTAL.
460 - aio requests can be cancelled.
461 - callbacks can be (re-)set later.
462 - aio requests can choose between 9 priorities.
463 - add aio_group: aio requests can be grouped
464 into composite requests.
465 - generator interface for groups.
466 - add IO::AIO::poll_some.
467 - major documentation improvements.
468 - very minor bugfixes.
469 - add aio_nop for dummy requests.
470 - add aio_busy mainly for benchmarking and debugging.
471 - use "fast" mutexes on linux.
472 - use dynamic (and larger) buffers instead of
473 putting them onto the stack.
474 - optimise x86 and amd64 a bit.
475 - better error checking when ENOMEM.
476 - hopefully fix mem and dirp leaks on fork.
477 - warn about broken perl malloc.
478 - compiles on cygwin (but pread is broken on cygwin
479 which is not detected by autoconf, so you have to
480 edit autoconf/config.h yourself to enable emulation).
481
482 1.8 Sat Jun 24 22:20:44 CEST 2006
483 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
484
485 1.73 Wed Mar 1 22:49:32 CET 2006
486 - codename "jost"
487 - AIX/Solaris(?) aren't being helpful again, hardcode a value
488 for NAME_MAX and drive with your eyes closed (reported by
489 wcooley@nakedape.cc).
490
491 1.72 Thu Feb 2 00:40:44 CET 2006
492 - another minor bug in aio_scandir, again, the callback was called
493 twice when the directory can't be stat'ed.
494
495 1.71 Mon Dec 26 20:20:03 CET 2005
496 - grr, another minor bug in aio_scandir, this time resulting
497 in a runtime error.
498
499 1.7 Mon Dec 26 19:29:48 CET 2005
500 - aio_scandir errornously called callback twice in some cases.
501 - added AnyEvent example.
502
503 1.61 Wed Sep 7 19:40:42 CEST 2005
504 - no longer include $Config{libs}, as distros include too much
505 garbage in there that is not installed on typical systems
506 (for example, debian links perl against -lgdbm and many more
507 libraries despite perl not needing it, slowing down startup and
508 wasting memory).
509
510 1.6 Tue Aug 30 17:44:44 CEST 2005
511 - added aio_readdir, aio_scandir.
512 - added aio_sendfile, including sendfile emulation when sendfile
513 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
514 support is unavailable on my solaris 8 machine, but preliminary
515 code is there. What's lacking is configury stuff and testing...).
516
517 1.5 Sat Aug 20 02:32:19 CEST 2005
518 - create the aio threads on demand only (good after forking).
519 - somebody nagged about C89 compatibility, so this release should
520 be C89 compatible, but no guarantees for future ones.
521 - abort when the configure script fails.
522
523 1.4 Wed Aug 17 08:07:27 CEST 2005
524 - forgot to recreate the pipe after forking, this could cause
525 deadlocks.
526
527 1.3 Wed Aug 17 07:25:54 CEST 2005
528 - properly propagate exceptions from callbacks, instead of silently
529 eating them.
530 - use a different fork algorithm that avoids recursive callback
531 invocations and reduces fork latency in busy processes.
532 - fix a bug where the buffer scalar in aio_read got assigned the wrong
533 length after reading.
534 - fix a bug where the child would process some outstanding requests
535 from the parent.
536 - make a copy of the callback scalar, to avoid some very uncommon
537 (but valid) usages where the callback scalar changes.
538 - the callback was never freed in aio_read/aio_write.
539 - aio_read/aio_write will now set the readonly flag on the data
540 scalar for better error reporting.
541
542 1.2 Wed Aug 17 01:22:58 CEST 2005
543 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
544 - use SvPVbyte for filenames now. You *need* to encode your strings to
545 the external filename encoding first.
546 - fix the bug where filehandles could leak (again).
547 - clarify freebsd situation: make it work and tell me how, or go away
548 with your underdocumented, broken and outdated OS.
549 - fork'ing should now be officially supported (where linux and
550 posix contradict each other, I followed posix).
551 - only call read() once per poll, not twice (speedup).
552 - new functions: aio_rmdir, aio_symlink.
553 - force callback arguments to be undef or a reference, for better
554 error catching.
555
556 1.1 Sun Aug 7 05:27:23 CEST 2005
557 - added configure script to detect availability of some calls.
558 (imperfect, as we cannot detect things like -lrt due to missing
559 feedback yet).
560 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
561 and readahead via manual reading on platforms lacking those.
562 - ported t/03_errors.t+framework by Brad Fitzpatrick
563 from Linux::AIO.
564 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
565 compile with it enabled. Probably breaks others. Oh well.
566 - try to be more careful with errno on non-threaded perls.
567 - cygwins perl insisted on a matching open mode when morphing
568 the fd to an fh.
569 - convert sv's to "byte" encoding in aio_read/aio_write. Might
570 do that for pathnames, too, in the future, so make sure you
571 properly encode your pathnames.
572
573 1.0 Fri Jul 22 10:43:30 CEST 2005
574 - aio_open did not reliably deliver (open) filehandles.
575 - all aio_*-functions keep a reference to the filehandle so
576 it doesn't go away while the aio requests is working on it.
577 - disable warnings in AIO.pm.
578
579 0.9 Wed Jul 20 23:55:04 CEST 2005
580 - allow recursive calls to poll_cb, use less locking calls, too.
581 - fix the Gtk2-example in the SYNOPSIS.
582 - use pread/pwrite not pread64/pwrite64. this was simply a leftover
583 from Linux::AIO.
584 (found by compiling on cygwin. Unfortunately, cygwin declares but
585 does not implement pread/pwrite).
586 - only include <sys/syscall.h> on linux.
587
588 0.5 Tue Jul 12 13:03:09 CEST 2005
589 - removed #include <endian.h>, it's not portable, and we don't
590 need it anyway.
591 - link against -lrt, as it might contain goodies such as fdatasync,
592 and often aio_read, which we do not use yet, but it shouldn't hurt.
593
594 0.4 Mon Jul 11 05:28:25 CEST 2005
595 - added IO::AIO::flush, IO::AIO::poll.
596 - make callback argument optional for all calls.
597
598 0.3 Mon Jul 11 01:42:37 CEST 2005
599 - restructured manpage.
600 - added SYNOPSIS with examples for Event, Glib, Tk.
601 - remove explicit context support so I don't have to maintain
602 it for threaded perls (i.e. it should work now :).
603
604 0.2 Sun Jul 10 22:57:12 CEST 2005
605 - return immediately from poll_wait if nreqs==0.
606 - get rid of the request pipe and use faster thread-thread
607 communications for most requests and responses.
608
609 0.1
610 - cloned from Linux::AIO, which is very similar.
611
