414.54 Tue Aug 14 13:54:48 CEST 2018
42 - include sys/mkdev.h or sys/sysmacros.h if available.
43 - further tweaks to configure invocation for systems requiring --rpath.
44 - no longer rely on custom paths on win32 platforms.
45 - try to work around buggy PAGESIZE macro on solaris.
46
474.53 Tue Aug 14 11:27:50 CEST 2018
48 - add $Config{libs} to LIBS for configure, to work around systems
49 with broken library dependencies (... openbsd).
50
514.52 Sun Aug 12 08:09:45 CEST 2018
52 - config.h.in was missing in distribution.
53
544.51 Sun Aug 12 07:24:14 CEST 2018
55 - complete rework of the autoconf framework: IO::AIO now uses its own
56 config.h, separate from libeio, and tries to test the actual perl
57 environment, not the standard system environment.
58 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
59 stat functions.
60 - removed non-portable C++ syntax from eio.c.
61 - try to fix readdir tests on cygwin spuriously failing.
62
634.5 Wed Aug 1 00:23:55 CEST 2018
64 - aio_mtouch touch all pages as requested, not just the first page in most cases.

73 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
74 - point out that aio_copy overwrites existing files.
75 - removed filesystem magic number table from aio_statvfs docs as
76 statvfs doesn't actually return this info at all (statfs does).
77 - add a bunch of (mostly linux-specific) constants for use in ioctls
78 (see aio_ioctl docs).
79 - treescan now has a proper manpage and useful --help output.
80 - new option --sync in treescan, to sync everything in a subtree.
81 - changed default for aio_msync flags to MSYNC_SYNC.
82 - document offset/length behaviour of mprotect/madvise.
83 - support linux's renameat2 (via aio_rename2).

85 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
86 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
87 - (libeio) use posix_close if available.
88 - (libeio) internal close() calls no longer disturb errno.
89 - add IO:AIO::FALLOC_FL_UNSHARE.
90 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
91 and better eventfd detection.
92
934.34 Sun May 1 19:18:24 CEST 2016
94 - def0.h was not properly generated during previous release, causing
95 compile errors on various platforms.
96 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
97 - removed duplicate definition of MAP_HUGETLB, that was found due to
98 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
99 - added (untested!) aio_fcntl, aio_ioctl requests.
100 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
101 as manpages-dev originally claimed.
102
1034.33 Mon Jan 18 12:50:10 CET 2016
104 - add IO::AIO::pipe2 function.
105 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
106 constants.
107 - added support for O_TMPFILE and O_PATH constants.
108 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK

114
1154.32 Wed Feb 11 20:32:11 CET 2015
116 - replace off_t by STRLEN where appropriate, should not result in
117 user-visible changes.
118 - update ecb.h for C11 compatibility.
119
1204.31 Tue Jun 3 03:29:27 CEST 2014
121 - work around more 5.20 bugs. backwards compatibility my ass.
122
1234.3 Fri Apr 11 06:22:38 CEST 2014
124 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
125 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
126 in 5.18. What's so attractive about giving a shit about backwards
127 compatibility - I will never understand.
128
1294.2 Sat Jan 25 01:13:14 CET 2014
130 - aio_group could corrupt memory because it didn't restore
131 the stack after req_submit.
132 - be more careful on (e.g. permission) errors in bin/treescan.
133 - work around changes in ExtUtils::MakeMaker.
134 - (libeio) implement aio_realpath for win32.
135 - (xthread) work around compile time bugs in ptw32.

138
1394.19 Sun Jan 6 12:47:26 CET 2013
140 - avoid endless loop in fiemap with some XFS files.
141 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
142 and call rename/rmdir instead of renameat/unlinkat.
143
1444.18 Thu Oct 11 07:01:26 CEST 2012
145 - fix unintended xthread_create by intentionalising it :)
146
1474.17 Thu Oct 11 05:19:47 CEST 2012
148 - rename aio_fallocate to aio_allocate, to match documentation.
149 - add list of linux fsid values to aio_statvfs docs.
150 - work around a bug in btrfs' FIEMAP ioctl implementation.
151 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
152 as per unix spec.
153
1544.16 Tue Aug 14 05:39:03 CEST 2012
155 - aio_statvfs was wromgly marked for wd emulation, causing
156 it to malfunction for paths.
157 - fix a crash in aio_fiemap, when used on ranges without any
158 extents.
159 - work around linux kernel bug (at least in 3.2): kernel might
160 trash fiemap input arguments.
161 - work around linux kernel bug (at least in 3.2): kernel does not
162 set FIEMAP_EXTENT_LAST on last segment.
163 - work around linux kernel bug (at least in 3.2): kernel silently
164 truncates segment count if a file.
165 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
166 to quick overview.
167 - splice can corrupt data.
168 - (libeio) remove pread/pwrite emulation.
169 - do not grow mmaped scalars in aio_read.

172
1734.15 Tue Apr 10 06:59:00 CEST 2012
174 - always include linux/types.h for fiemap, for compatibility to
175 ancient systems (Paul Howarth).
176 - experimental support for IO::AIO::splice and ::tee (no aio_...).
177 - provide SEEK_HOLE and SEEK_DATA, if available.
178 - work around (again!) an immensely stupid bug in RHEL, defining
179 autoconf macros in linux system headers (analysed by Paul Howarth).
180
1814.14 Sat Apr 7 02:45:18 CEST 2012
182 - fix stat structure usage on windows, which caused bogus stat results.
183 - (libeio) make readahead emulation behave more like actual readahead by never failing.
184 - new request aio_seek.
185 - new request aio_fiemap.
186 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
187
1884.12 Fri Dec 30 08:51:25 CET 2011
189 - realpath would return a random value if the name was too long,
190 instead of -1.
191 - port to c89.
192
1934.11 Mon Oct 10 00:24:11 CEST 2011
194 - libeio didn't compile on !linux (Paul Howarth).
195
1964.1 Sun Oct 9 10:24:11 CEST 2011
197 - IO::AIO did access uninitialised memory on unsuccessful stats.
198 - (libeio) added syncfs syscall wrapper.
199 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
200 - (libeio) support multiple indepenent working directories.
201 - applied speling corrections by Nicholas Bamber.
202 - tune treescan #threads and #outstanding requests a bit.
203 - reduce the number of file descriptors in use at any one time
204 in treescan, to avoid running out of them (and using too much ram).
205 - take advantage of working directoriy abstractions
206 in aio_scandir and treescan.
207 - reduce compiled size by ~10% by not inlining some key functionality.
208 - added --progress switch to treescan.
209
2104.0 Mon Jul 18 05:01:10 CEST 2011
211 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
212 see FORK BEHAVIOUR in manpage for details.
213 - passes testsuite on win32 now and may actually work
214 (activestate 5.10.1 / MSVC6, YMMV).
215 - (libeio) fix a deadlock where a wakeup signal could be missed when
216 a timeout occured at the same time.
217 - (libeio) added realpath.
218 - (libeio) added fallocate.
219 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.

222
2233.93 Wed Jun 29 23:44:18 CEST 2011
224 - ECB.H WAS MISSING.
225
2263.92 Wed Jun 29 14:45:41 CEST 2011
227 - ecb.h was missing.
228
2293.91 Wed Jun 29 13:24:42 CEST 2011
230 - (libeio) work around a Linux (and likely FreeBSD and other
231 kernels) bug where sendfile would not transfer all the requested
232 bytes on large transfers, using a heuristic.
233 - buggy sendfile caused aio_move/copy to sometimes fail for big
234 files (fortunately it checks that the whole file has been
235 transferred...)
236 - use libecb for higher performance and higher portability.
237 - (libeio) disable sendfile on darwin, it's too broken.
238 - disable fork tests on !linux, as only linux supports mixing
239 pthread and fork in perl.
240 - document the fact that fork doesn't work anymore when using
241 this module, on anything !GNU/Linux.
242 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
243 run on a 0.1MHz cpu. Or so.
244
2453.9 Fri May 27 02:43:47 CEST 2011
246 - (libeio) fix memory corruption in aio_readdirx for the flags
247 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
248 - add lots of newer POSIX and GNU/Linux-specific open
249 flags.
250
2513.8 Sun Mar 27 12:25:33 CEST 2011
252 - use nonstandard but maybe-working-on-bsd fork technique.
253 - support a max_idle value of 0.
254 - support setting of idle timeout value (IO::AIO::idle_timeout).
255
2563.72 Fri Feb 11 04:25:38 CET 2011
257 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
258 - aio_mknod always used a dev_t value of 0.
259 - new treescan option: --grep.
260 - add more S_IF macros, and major/minor/makedev "macros".
261
2623.71 Thu Dec 30 08:18:46 CET 2010
263 - the numerical result value passed to callbacks did not stringify
264 correctly, due to internal reuse and failure to reset the sv flags.
265 - actually test for posix_[mf]advise, as at least uClibc defines
266 _POSIX_ADVISORY_INFO without actually having any of the required
267 funcitonality. ugh.
268
2693.7 Mon Nov 1 23:00:34 CET 2010
270 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
271 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
272 - document the sad state of affairs w.r.t. pthread on many bsds.
273 - do not enable mmap on systems without _POSIX_MAPPED_FILES
274 (openbsd 4.8).
275 - do not leak memory in IO::AIO::mmap when the scalar already
276 had string-data.
277 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
278 them.
279 - cache the result IV, for a minor speedup in the common case.
280 - croak when an mmapped-scalar changes location, to detect
281 user-errors better.
282 - fix aio_readlink prototype.
283
2843.65 Wed Mar 31 02:45:05 CEST 2010
285 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
286 cut off long pathnames in aio_readlink (based on patch by
287 Rasmus Andersson).
288 - a double fork partially killed the event pipe (great testcase
289 by dormando). affects IO::AIO, BDB and Async::Interrupt.
290 - suck steve's dick and rename our symbols to avoid colliding
291 with nonstandard identifier spam on the broken os x pseudo-os.
292 affects IO::AIO and BDB.
293
2943.6 Mon Jan 11 00:43:39 CET 2010
295 - (libeio) more fixes for the freebsd/apple sendfile - broken by
296 manpage standards, but apparently correct accoridng to actual
297 kernel sources.
298 - add IO::AIO::mmap/munmap support.
299 - add IO::AIO::m(un)lockall support.
300 - clean up manpage.
301
3023.5 Thu Jan 7 21:25:04 CET 2010
303 - (liebio) fix freebsd sendfile (Vanilla Hsu).
304 - (libeio) also fix darwin sendfile that suffered from a similar bug.
305 - add aio_statvfs as interface to statvfs/fstatvfs.
306 - work around buggy symlink() on cygwin in the testsuite.
307 - wtf. freebsd-8.0 actually passes the testsuite! I knew
308 they could implement fork and semaphores one day! cheers!
309
3103.4 Sat Jan 2 15:13:04 CET 2010
311 - (libeio) max_poll_time was not properly converted to ticks.
312 - clarify cancel_subs description.
313 - IO::AIO::sendfile did not actually return the return value
314 from the sendfile call.
315 - implement aio_msync, aio_mtouch.
316 - (libeio) tentatively support darwin in sendfile.
317
3183.31 Thu Nov 12 02:14:29 CET 2009
319 - fix result status documentation of aio_copy, aio_move.
320 - speed up object creation considerably by avoiding
321 hash lookups.
322
3233.3 Wed Aug 5 13:52:58 CEST 2009
324 - use common::sense.
325 - use common schmorp.h header.
326 - allow integers (file descriptors) in addition to file handles.
327 - take advantage of linux' eventfd (but it seems slower on smp?).
328 - use poll not select on posix platforms.
329
3303.261 Wed Jul 1 10:11:51 CEST 2009
331 - more 0S X workarounds (patch by Tokuhiro Matsuno).
332
3333.26 Tue Jun 30 09:33:26 CEST 2009
334 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
335 try to work around this horribly broken OS in a somewhat hackish
336 way. might help other os's too.
337
3383.25 Sat Jun 27 05:18:26 CEST 2009
339 - added IO::AIO::fadvise and IO::AIO::sendfile.
340 - (libeio) replaced quicksort+insertion sort by a tuned radix
341 sort + insertion sort, resulting in comparable runtime (usually
342 faster) to the old version, but without any ill side effects on
343 degenerated (for quicksort) data.
344 - (libeio) correctly sort dirs by inodes if we have perfect type
345 knowledge and DIRS_FIRST is used.
346 - (libeio) internally the wrong DT_* constants were used, but no
347 known system has differing EIO_DT_*/DT_* values, so not an issue.
348 - removed a (harmless) assert that was left over on the code
349 but should not have been.
350 - use more correct types (change IO length from IV to VAL64,
351 which makes a difference on systems without 64 bit perls).
352
3533.23 Sat Jun 13 16:57:58 CEST 2009
354 - fix off-by-one bug in aio_readdir that was introduced in the
355 rushed 3.22 release.
356
3573.22 Sat Jun 13 15:32:40 CEST 2009
358 - speed up readdirx sort algorithm slightly.
359 - bin/treescan was missing from distro tarball.
360
3613.21 Fri Jun 12 18:45:53 CEST 2009
362 - new options --dirs and --files for treescan.
363 - install bin/treescan by default.
364 - (libeio) aio_readdir can now be cancelled while executing.
365 - fix a printf format string for 64 bit systems (could lead
366 to problems on big endian 64 bit systems).
367 - do not use qsort() but our own algorithm: glibc initialises
368 the whole locale and I/O subsystem inside qsort, causing
369 a stack overflow on 32 bit machines. The new sort uses much less
370 stack and is more than twice as fast in typical situations.
371
3723.2 Sun Jun 7 20:30:05 CEST 2009
373 - (libeio) pwrite emulation was even more flawed than intended and did
374 not restore the file offset.
375 - add aio_readdirx, which can return inode and filetype and sort
376 the names in various ways.
377 - unfortunately, utime, chmod, chown on an open file that has just
378 been written can easily block, which caused aio_copy to block the
379 process. no more!
380 - no longer rely on dst path in aio_copy when futime is available.
381
3823.19 Tue Apr 21 22:05:21 CEST 2009
383 - more perl 5.10 workarounds for aio_read and write.
384 - aio_write no longer modifies the sv (if possible).
385 - aio_read now works correctly with magic values.
386
3873.18 Sun Apr 19 21:17:32 CEST 2009
388 - better diagnostics when some aio_* functions get passed an illegal fh.
389 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
390
3913.17 Thu Nov 20 08:45:36 CET 2008
392 - (libeio) added aio_sync_file_range (untested).
393 - add aio_busy to @IO::AIO::AIO_REQ.
394
3953.16 Wed Oct 22 18:28:01 CEST 2008
396 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
397 part to improve portability to perl 5.8 (reported by szymon).
398
3993.15 Mon Oct 13 00:39:55 CEST 2008
400 - automatic removal of feeders was broken.
401 - (libeio) use a more robust method to detect whether a feeder
402 has added something to the group or not.
403
4043.1 Thu Oct 2 13:34:40 CEST 2008
405 - pre-deref the passed callback object, for increased speed
406 and decreased memory usage.
407 - call on_next_submit callback even for aio_group - impact unknown,
408 but seems more correct.
409 - $req->cb now returns the original callback.
410 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
411 requiring a thread switch.
412 - (libeio) status code of aio_futime and aio_utime was always passed 0.
413 - do some other ยต-optimisations.
414
4153.07 Sat Aug 2 16:06:13 CEST 2008
416 - do not include LIBS in autoconf tests.
417
4183.06 Tue Jul 15 12:41:32 CEST 2008
419 - move preadwritelock definition before it's first reference,
420 to make it compile again on broken platforms (they still exist)
421 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
422
4233.05 Thu Jun 19 23:23:52 CEST 2008
424 - work around perl overriding readdir etc. with thread-unsafe
425 (sic!) versions.
426
4273.04 Wed Jun 18 01:35:38 CEST 2008
428 - (libeio) fix eio_mknod, which confused it's arguments.
429 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
430 is stupid.
431 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
432 - (libeio) fix a bug that could potentially cause IO::AIO
433 not to get initialised properly.
434
4353.03 Thu May 29 05:33:30 CEST 2008
436 - (libeio) correctly call pthread_attr_destroy ().
437 - (libeio) work around broken bsd headers once more.
438 - reduce shared library size again by not including wrappers.
439 - max_outstanding could cause poll to enter a busy-waiting loop.
440 - document the new IO::AIO::poll_cb result value.
441
4423.02 Mon May 12 02:32:02 CEST 2008
443 - fix a memory leak on aio_readlink.
444 - bring back working fchmod.
445 - nop and busy now set result to 0.
446 - set errno to ENOMEM when allocation fails.
447
4483.01 Sun May 11 03:07:03 CEST 2008
449 - (libeio) make it compile on systems without readahead or readdir_r.
450 - (libeio) improve configure check for readahead availability.
451 - do not try to link against -lrt.
452 - use a separate configure script for IO::AIO (not the libeio one).
453
4543.0 Sun May 11 00:57:14 CEST 2008
455 - added bin/treescan to the distribution.
456 - switched to using libeio.
457 - LOTS OF INCOMPATIBLE CHANGES:
458 - remove signal functionality, it is not worth the effort.
459 - max_outstanding no longer returns the previous number of requests.
460 - poll_cb no longer returns number of requests.
461
4622.62 Sat Apr 26 13:59:33 CEST 2008
463 - port to solaris perls configured for old posix
464 (analysed by Jost Krieger).
465 - keep a reference to the perl filehandle object in aio_close,
466 so it doesn't get closed prematurely, leading to ugly races.
467
4682.61 Wed Apr 16 18:45:02 CEST 2008
469 - fix treescan output duplication and improve output ordering.
470 also display files given on the commandline.
471 - use a different algorithm for aio_close that is faster
472 and probably has even lower chances of blocking.
473 - do our own stack memory management for threads - linux
474 allocates outrageous amounts of VM (not so bad unless you
475 use mlockall...), which severely limits the number of threads
476 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
477 and 4096 * sizeof (long) (usually this is 16..64k).
478
4792.6 Sun Mar 30 08:28:11 CEST 2008
480 - added aio_sync.
481 - added aio_pathsync.
482 - fix prototypes of (void) functions.
483
4842.51 Sat Oct 6 16:04:54 CEST 2007
485 - perlio isn't generally threadsafe, so aio_close could not work reliably.
486 aio_close now tries a safe hack that might not be that asynchronous
487 (see the manpage for details).
488 - discard callback return values as to not grow the stack endlessly
489 when poll_cb handles many requests without returning.
490 - minor code cleanups.
491
4922.5 Thu Oct 4 14:49:08 CEST 2007
493 - replaced _fd2fh with faster xs code.
494 - aio_close will now try to do "the right thing" and thus might
495 work sensibly for the very first time.
496
4972.41 Mon Sep 24 21:28:21 CEST 2007
498 - after fork, invest some work to make sure that the poll_fileno
499 stays stable (by dup2'ing the new fd over the old one), to make
500 it easier for programs/libs that don't control their forking
501 behaviour and cannot recreate their watchers.
502
5032.4 Sun Aug 5 18:44:22 CEST 2007
504 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
505 successfully demonstrated that you can block on futimes...).
506 - allow undef as fileoffset for aio_read/write and use read/write(2)
507 internally (useful for sockets or O_APPEND handles).
508 - allow undef for length in aio_write.
509 - negative dataoffsets work as expected now in aio_read/aio_write.
510 - use NV instead of UV for 32 bit perls and file offsets, as NVs
511 have a larger range then.
512 - shared code between BDB and IO::AIO.
513 - aio_busy was completely broken. now fixed.
514 - readahead emulation now returns something.
515 - correctly set errno to ENOSYS on unimplemented functions
516 (should never happen, though).
517 - large changes to make it partially compile and run on win32,
518 but win32 lacks too much functionality, and perl overrides way
519 too many functions with crashing versions.
520
5212.33 Tue Jan 23 23:55:41 CET 2007
522 - fix install path (Andreas J. Koenig).
523
5242.32 Mon Jan 22 16:56:23 CET 2007
525 - added aio_rmtree.
526 - wow, aio_mkdir was missing.
527 - aio_load did return undef on error, not -1.
528 - use prefixexp not prefix in autoconf.pm
529 (suggested by ... rt.cpan.org unreachable).
530 - avoid installing autoconf.pm.
531
5322.31 Sat Jan 6 03:46:02 CET 2007
533 - added aio_load.
534
5352.3 Sat Dec 23 05:48:07 CET 2006
536 - fix off-by-one bug in aio_read, causing memory corruption
537 or crashes.
538
5392.21 Fri Dec 22 05:03:38 CET 2006
540 - minor doc updates.
541 - minor cleanups.
542 - IO::AIO::poll returns request count.
543 - undocumented and unfinished async-signal-reporting.
544
5452.2 Tue Oct 31 00:31:00 CET 2006
546 - minor doc updates.
547 - added aio_readlink.
548 - properly zero-terminate aio_read buffer.
549 - fix aio_read/write with nonzero dataoffset.
550 - reduced size of aio request structure.
551 - better diagnostics when pathnames etc. are not byte-encoded;
552 do not leak request in that case, either.
553
5542.1 Sun Oct 29 02:01:57 CET 2006
555 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
556 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
557 - fix a bug in aio_move where it would fail everytime
558 it would have to copy files manually.
559 - doc updates.
560 - start threads only on (very low) demand.
561 - end superfluous threads automatically after 10s idling.
562 - add IO::AIO::max_idle to control this.
563 - some tuning applied to random places.
564 - add aio_mknod.
565
5662.0 Thu Oct 26 18:27:58 CEST 2006
567 - minor incompatibility: max_outstanding semantics have changed.
568 - major rewrite, consider all functionality EXPERIMENTAL.
569 - aio requests can be cancelled.
570 - callbacks can be (re-)set later.
571 - aio requests can choose between 9 priorities.
572 - add aio_group: aio requests can be grouped
573 into composite requests.
574 - generator interface for groups.
575 - add IO::AIO::poll_some.
576 - major documentation improvements.
577 - very minor bugfixes.
578 - add aio_nop for dummy requests.
579 - add aio_busy mainly for benchmarking and debugging.
580 - use "fast" mutexes on linux.
581 - use dynamic (and larger) buffers instead of
582 putting them onto the stack.
583 - optimise x86 and amd64 a bit.
584 - better error checking when ENOMEM.
585 - hopefully fix mem and dirp leaks on fork.
586 - warn about broken perl malloc.
587 - compiles on cygwin (but pread is broken on cygwin
588 which is not detected by autoconf, so you have to
589 edit autoconf/config.h yourself to enable emulation).
590
5911.8 Sat Jun 24 22:20:44 CEST 2006
592 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
593
5941.73 Wed Mar 1 22:49:32 CET 2006
595 - codename "jost"
596 - AIX/Solaris(?) aren't being helpful again, hardcode a value
597 for NAME_MAX and drive with your eyes closed (reported by
598 wcooley@nakedape.cc).
599
6001.72 Thu Feb 2 00:40:44 CET 2006
601 - another minor bug in aio_scandir, again, the callback was called
602 twice when the directory can't be stat'ed.
603
6041.71 Mon Dec 26 20:20:03 CET 2005
605 - grr, another minor bug in aio_scandir, this time resulting
606 in a runtime error.
607
6081.7 Mon Dec 26 19:29:48 CET 2005
609 - aio_scandir errornously called callback twice in some cases.
610 - added AnyEvent example.
611
6121.61 Wed Sep 7 19:40:42 CEST 2005
613 - no longer include $Config{libs}, as distros include too much
614 garbage in there that is not installed on typical systems
615 (for example, debian links perl against -lgdbm and many more
616 libraries despite perl not needing it, slowing down startup and
617 wasting memory).
618
6191.6 Tue Aug 30 17:44:44 CEST 2005
620 - added aio_readdir, aio_scandir.
621 - added aio_sendfile, including sendfile emulation when sendfile
622 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
623 support is unavailable on my solaris 8 machine, but preliminary
624 code is there. What's lacking is configury stuff and testing...).
625
6261.5 Sat Aug 20 02:32:19 CEST 2005
627 - create the aio threads on demand only (good after forking).
628 - somebody nagged about C89 compatibility, so this release should
629 be C89 compatible, but no guarantees for future ones.
630 - abort when the configure script fails.
631
6321.4 Wed Aug 17 08:07:27 CEST 2005
633 - forgot to recreate the pipe after forking, this could cause
634 deadlocks.
635
6361.3 Wed Aug 17 07:25:54 CEST 2005
637 - properly propagate exceptions from callbacks, instead of silently
638 eating them.
639 - use a different fork algorithm that avoids recursive callback
640 invocations and reduces fork latency in busy processes.
641 - fix a bug where the buffer scalar in aio_read got assigned the wrong
642 length after reading.
643 - fix a bug where the child would process some outstanding requests
644 from the parent.
645 - make a copy of the callback scalar, to avoid some very uncommon
646 (but valid) usages where the callback scalar changes.
647 - the callback was never freed in aio_read/aio_write.
648 - aio_read/aio_write will now set the readonly flag on the data
649 scalar for better error reporting.
650
6511.2 Wed Aug 17 01:22:58 CEST 2005
652 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
653 - use SvPVbyte for filenames now. You *need* to encode your strings to
654 the external filename encoding first.
655 - fix the bug where filehandles could leak (again).
656 - clarify freebsd situation: make it work and tell me how, or go away
657 with your underdocumented, broken and outdated OS.
658 - fork'ing should now be officially supported (where linux and
659 posix contradict each other, I followed posix).
660 - only call read() once per poll, not twice (speedup).
661 - new functions: aio_rmdir, aio_symlink.
662 - force callback arguments to be undef or a reference, for better
663 error catching.
664
6651.1 Sun Aug 7 05:27:23 CEST 2005
666 - added configure script to detect availability of some calls.
667 (imperfect, as we cannot detect things like -lrt due to missing
668 feedback yet).
669 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
670 and readahead via manual reading on platforms lacking those.
671 - ported t/03_errors.t+framework by Brad Fitzpatrick
672 from Linux::AIO.
673 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
674 compile with it enabled. Probably breaks others. Oh well.
675 - try to be more careful with errno on non-threaded perls.
676 - cygwins perl insisted on a matching open mode when morphing
677 the fd to an fh.
678 - convert sv's to "byte" encoding in aio_read/aio_write. Might
679 do that for pathnames, too, in the future, so make sure you
680 properly encode your pathnames.
681
6821.0 Fri Jul 22 10:43:30 CEST 2005
683 - aio_open did not reliably deliver (open) filehandles.
684 - all aio_*-functions keep a reference to the filehandle so
685 it doesn't go away while the aio requests is working on it.
686 - disable warnings in AIO.pm.
2 687
30.9 Wed Jul 20 23:55:04 CEST 2005 6880.9 Wed Jul 20 23:55:04 CEST 2005
4 - allow recursive calls to poll_cb, use less locking calls, too. 689 - allow recursive calls to poll_cb, use less locking calls, too.
5 - fix the Gtk2-example in the SYNOPSIS. 690 - fix the Gtk2-example in the SYNOPSIS.
6 - use pread/pwrite not pread64/pwrite64. this was simply a leftover 691 - use pread/pwrite not pread64/pwrite64. this was simply a leftover
