254.31 Tue Jun 3 03:29:27 CEST 2014
26 - work around more 5.20 bugs. backwards compatibility my ass.
27
284.3 Fri Apr 11 06:22:38 CEST 2014
29 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
30 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
31 in 5.18. What's so attractive about giving a shit about backwards
32 compatibility - I will never understand.
33
344.2 Sat Jan 25 01:13:14 CET 2014
35 - aio_group could corrupt memory because it didn't restore
36 the stack after req_submit.
37 - be more careful on (e.g. permission) errors in bin/treescan.
38 - work around changes in ExtUtils::MakeMaker.
39 - (libeio) implement aio_realpath for win32.
40 - (xthread) work around compile time bugs in ptw32.
41 - added IO::AIO::pipesize.
42 - (libecb) insignificant update.
43
444.19 Sun Jan 6 12:47:26 CET 2013
45 - avoid endless loop in fiemap with some XFS files.
46 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
47 and call rename/rmdir instead of renameat/unlinkat.
48
494.18 Thu Oct 11 07:01:26 CEST 2012
50 - fix unintended xthread_create by intentionalising it :)
51
524.17 Thu Oct 11 05:19:47 CEST 2012
53 - rename aio_fallocate to aio_allocate, to match documentation.
54 - add list of linux fsid values to aio_statvfs docs.
55 - work around a bug in btrfs' FIEMAP ioctl implementation.
56 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
57 as per unix spec.
58
594.16 Tue Aug 14 05:39:03 CEST 2012
60 - aio_statvfs was wromgly marked for wd emulation, causing
61 it to malfunction for paths.
62 - fix a crash in aio_fiemap, when used on ranges without any
63 extents.
64 - work around linux kernel bug (at least in 3.2): kernel might
65 trash fiemap input arguments.
66 - work around linux kernel bug (at least in 3.2): kernel does not
67 set FIEMAP_EXTENT_LAST on last segment.
68 - work around linux kernel bug (at least in 3.2): kernel silently
69 truncates segment count if a file.
70 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
71 to quick overview.
72 - splice can corrupt data.
73 - (libeio) remove pread/pwrite emulation.
74 - do not grow mmaped scalars in aio_read.
75 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
76 - provide pread/pwrite for win32, making it link again on native win32.
77
784.15 Tue Apr 10 06:59:00 CEST 2012
79 - always include linux/types.h for fiemap, for compatibility to
80 ancient systems (Paul Howarth).
81 - experimental support for IO::AIO::splice and ::tee (no aio_...).
82 - provide SEEK_HOLE and SEEK_DATA, if available.
83 - work around (again!) an immensely stupid bug in RHEL, defining
84 autoconf macros in linux system headers (analysed by Paul Howarth).
85
864.14 Sat Apr 7 02:45:18 CEST 2012
87 - fix stat structure usage on windows, which caused bogus stat results.
88 - (libeio) make readahead emulation behave more like actual readahead by never failing.
89 - new request aio_seek.
90 - new request aio_fiemap.
91 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
92
934.12 Fri Dec 30 08:51:25 CET 2011
94 - realpath would return a random value if the name was too long,
95 instead of -1.
96 - port to c89.
97
984.11 Mon Oct 10 00:24:11 CEST 2011
99 - libeio didn't compile on !linux (Paul Howarth).
100
1014.1 Sun Oct 9 10:24:11 CEST 2011
102 - IO::AIO did access uninitialised memory on unsuccessful stats.
103 - (libeio) added syncfs syscall wrapper.
104 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
105 - (libeio) support multiple indepenent working directories.
106 - applied speling corrections by Nicholas Bamber.
107 - tune treescan #threads and #outstanding requests a bit.
108 - reduce the number of file descriptors in use at any one time
109 in treescan, to avoid running out of them (and using too much ram).
110 - take advantage of working directoriy abstractions
111 in aio_scandir and treescan.
112 - reduce compiled size by ~10% by not inlining some key functionality.
113 - added --progress switch to treescan.
114
1154.0 Mon Jul 18 05:01:10 CEST 2011
116 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
117 see FORK BEHAVIOUR in manpage for details.
118 - passes testsuite on win32 now and may actually work
119 (activestate 5.10.1 / MSVC6, YMMV).
120 - (libeio) fix a deadlock where a wakeup signal could be missed when
121 a timeout occured at the same time.
122 - (libeio) added realpath.
123 - (libeio) added fallocate.
124 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
125 - (libeio) do not acquire any locks when forking.
126 - (libeio) use fewer time() syscalls when waiting for new requests.
127
1283.93 Wed Jun 29 23:44:18 CEST 2011
129 - ECB.H WAS MISSING.
130
1313.92 Wed Jun 29 14:45:41 CEST 2011
132 - ecb.h was missing.
133
1343.91 Wed Jun 29 13:24:42 CEST 2011
135 - (libeio) work around a Linux (and likely FreeBSD and other
136 kernels) bug where sendfile would not transfer all the requested
137 bytes on large transfers, using a heuristic.
138 - buggy sendfile caused aio_move/copy to sometimes fail for big
139 files (fortunately it checks that the whole file has been
140 transferred...)
141 - use libecb for higher performance and higher portability.
142 - (libeio) disable sendfile on darwin, it's too broken.
143 - disable fork tests on !linux, as only linux supports mixing
144 pthread and fork in perl.
145 - document the fact that fork doesn't work anymore when using
146 this module, on anything !GNU/Linux.
147 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
148 run on a 0.1MHz cpu. Or so.
149
1503.9 Fri May 27 02:43:47 CEST 2011
151 - (libeio) fix memory corruption in aio_readdirx for the flags
152 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
153 - add lots of newer POSIX and GNU/Linux-specific open
154 flags.
155
1563.8 Sun Mar 27 12:25:33 CEST 2011
157 - use nonstandard but maybe-working-on-bsd fork technique.
158 - support a max_idle value of 0.
159 - support setting of idle timeout value (IO::AIO::idle_timeout).
160
1613.72 Fri Feb 11 04:25:38 CET 2011
162 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
163 - aio_mknod always used a dev_t value of 0.
164 - new treescan option: --grep.
165 - add more S_IF macros, and major/minor/makedev "macros".
166
1673.71 Thu Dec 30 08:18:46 CET 2010
168 - the numerical result value passed to callbacks did not stringify
169 correctly, due to internal reuse and failure to reset the sv flags.
170 - actually test for posix_[mf]advise, as at least uClibc defines
171 _POSIX_ADVISORY_INFO without actually having any of the required
172 funcitonality. ugh.
173
1743.7 Mon Nov 1 23:00:34 CET 2010
175 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
176 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
177 - document the sad state of affairs w.r.t. pthread on many bsds.
178 - do not enable mmap on systems without _POSIX_MAPPED_FILES
179 (openbsd 4.8).
180 - do not leak memory in IO::AIO::mmap when the scalar already
181 had string-data.
182 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
183 them.
184 - cache the result IV, for a minor speedup in the common case.
185 - croak when an mmapped-scalar changes location, to detect
186 user-errors better.
187 - fix aio_readlink prototype.
188
1893.65 Wed Mar 31 02:45:05 CEST 2010
190 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
191 cut off long pathnames in aio_readlink (based on patch by
192 Rasmus Andersson).
193 - a double fork partially killed the event pipe (great testcase
194 by dormando). affects IO::AIO, BDB and Async::Interrupt.
195 - suck steve's dick and rename our symbols to avoid colliding
196 with nonstandard identifier spam on the broken os x pseudo-os.
197 affects IO::AIO and BDB.
198
1993.6 Mon Jan 11 00:43:39 CET 2010
200 - (libeio) more fixes for the freebsd/apple sendfile - broken by
201 manpage standards, but apparently correct accoridng to actual
202 kernel sources.
203 - add IO::AIO::mmap/munmap support.
204 - add IO::AIO::m(un)lockall support.
205 - clean up manpage.
206
2073.5 Thu Jan 7 21:25:04 CET 2010
208 - (liebio) fix freebsd sendfile (Vanilla Hsu).
209 - (libeio) also fix darwin sendfile that suffered from a similar bug.
210 - add aio_statvfs as interface to statvfs/fstatvfs.
211 - work around buggy symlink() on cygwin in the testsuite.
212 - wtf. freebsd-8.0 actually passes the testsuite! I knew
213 they could implement fork and semaphores one day! cheers!
214
2153.4 Sat Jan 2 15:13:04 CET 2010
216 - (libeio) max_poll_time was not properly converted to ticks.
217 - clarify cancel_subs description.
218 - IO::AIO::sendfile did not actually return the return value
219 from the sendfile call.
220 - implement aio_msync, aio_mtouch.
221 - (libeio) tentatively support darwin in sendfile.
222
2233.31 Thu Nov 12 02:14:29 CET 2009
224 - fix result status documentation of aio_copy, aio_move.
225 - speed up object creation considerably by avoiding
226 hash lookups.
227
2283.3 Wed Aug 5 13:52:58 CEST 2009
229 - use common::sense.
230 - use common schmorp.h header.
231 - allow integers (file descriptors) in addition to file handles.
232 - take advantage of linux' eventfd (but it seems slower on smp?).
233 - use poll not select on posix platforms.
234
2353.261 Wed Jul 1 10:11:51 CEST 2009
236 - more 0S X workarounds (patch by Tokuhiro Matsuno).
237
2383.26 Tue Jun 30 09:33:26 CEST 2009
239 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
240 try to work around this horribly broken OS in a somewhat hackish
241 way. might help other os's too.
242
2433.25 Sat Jun 27 05:18:26 CEST 2009
244 - added IO::AIO::fadvise and IO::AIO::sendfile.
245 - (libeio) replaced quicksort+insertion sort by a tuned radix
246 sort + insertion sort, resulting in comparable runtime (usually
247 faster) to the old version, but without any ill side effects on
248 degenerated (for quicksort) data.
249 - (libeio) correctly sort dirs by inodes if we have perfect type
250 knowledge and DIRS_FIRST is used.
251 - (libeio) internally the wrong DT_* constants were used, but no
252 known system has differing EIO_DT_*/DT_* values, so not an issue.
253 - removed a (harmless) assert that was left over on the code
254 but should not have been.
255 - use more correct types (change IO length from IV to VAL64,
256 which makes a difference on systems without 64 bit perls).
257
2583.23 Sat Jun 13 16:57:58 CEST 2009
259 - fix off-by-one bug in aio_readdir that was introduced in the
260 rushed 3.22 release.
261
2623.22 Sat Jun 13 15:32:40 CEST 2009
263 - speed up readdirx sort algorithm slightly.
264 - bin/treescan was missing from distro tarball.
265
2663.21 Fri Jun 12 18:45:53 CEST 2009
267 - new options --dirs and --files for treescan.
268 - install bin/treescan by default.
269 - (libeio) aio_readdir can now be cancelled while executing.
270 - fix a printf format string for 64 bit systems (could lead
271 to problems on big endian 64 bit systems).
272 - do not use qsort() but our own algorithm: glibc initialises
273 the whole locale and I/O subsystem inside qsort, causing
274 a stack overflow on 32 bit machines. The new sort uses much less
275 stack and is more than twice as fast in typical situations.
276
2773.2 Sun Jun 7 20:30:05 CEST 2009
278 - (libeio) pwrite emulation was even more flawed than intended and did
279 not restore the file offset.
280 - add aio_readdirx, which can return inode and filetype and sort
281 the names in various ways.
282 - unfortunately, utime, chmod, chown on an open file that has just
283 been written can easily block, which caused aio_copy to block the
284 process. no more!
285 - no longer rely on dst path in aio_copy when futime is available.
286
2873.19 Tue Apr 21 22:05:21 CEST 2009
288 - more perl 5.10 workarounds for aio_read and write.
289 - aio_write no longer modifies the sv (if possible).
290 - aio_read now works correctly with magic values.
291
2923.18 Sun Apr 19 21:17:32 CEST 2009
293 - better diagnostics when some aio_* functions get passed an illegal fh.
294 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
295
2963.17 Thu Nov 20 08:45:36 CET 2008
297 - (libeio) added aio_sync_file_range (untested).
298 - add aio_busy to @IO::AIO::AIO_REQ.
299
3003.16 Wed Oct 22 18:28:01 CEST 2008
301 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
302 part to improve portability to perl 5.8 (reported by szymon).
303
3043.15 Mon Oct 13 00:39:55 CEST 2008
305 - automatic removal of feeders was broken.
306 - (libeio) use a more robust method to detect whether a feeder
307 has added something to the group or not.
308
3093.1 Thu Oct 2 13:34:40 CEST 2008
310 - pre-deref the passed callback object, for increased speed
311 and decreased memory usage.
312 - call on_next_submit callback even for aio_group - impact unknown,
313 but seems more correct.
314 - $req->cb now returns the original callback.
315 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
316 requiring a thread switch.
317 - (libeio) status code of aio_futime and aio_utime was always passed 0.
318 - do some other ยต-optimisations.
319
3203.07 Sat Aug 2 16:06:13 CEST 2008
321 - do not include LIBS in autoconf tests.
322
3233.06 Tue Jul 15 12:41:32 CEST 2008
324 - move preadwritelock definition before it's first reference,
325 to make it compile again on broken platforms (they still exist)
326 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
327
3283.05 Thu Jun 19 23:23:52 CEST 2008
329 - work around perl overriding readdir etc. with thread-unsafe
330 (sic!) versions.
331
3323.04 Wed Jun 18 01:35:38 CEST 2008
333 - (libeio) fix eio_mknod, which confused it's arguments.
334 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
335 is stupid.
336 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
337 - (libeio) fix a bug that could potentially cause IO::AIO
338 not to get initialised properly.
339
3403.03 Thu May 29 05:33:30 CEST 2008
341 - (libeio) correctly call pthread_attr_destroy ().
342 - (libeio) work around broken bsd headers once more.
343 - reduce shared library size again by not including wrappers.
344 - max_outstanding could cause poll to enter a busy-waiting loop.
345 - document the new IO::AIO::poll_cb result value.
346
3473.02 Mon May 12 02:32:02 CEST 2008
348 - fix a memory leak on aio_readlink.
349 - bring back working fchmod.
350 - nop and busy now set result to 0.
351 - set errno to ENOMEM when allocation fails.
352
3533.01 Sun May 11 03:07:03 CEST 2008
354 - (libeio) make it compile on systems without readahead or readdir_r.
355 - (libeio) improve configure check for readahead availability.
356 - do not try to link against -lrt.
357 - use a separate configure script for IO::AIO (not the libeio one).
358
3593.0 Sun May 11 00:57:14 CEST 2008
360 - added bin/treescan to the distribution.
361 - switched to using libeio.
362 - LOTS OF INCOMPATIBLE CHANGES:
363 - remove signal functionality, it is not worth the effort.
364 - max_outstanding no longer returns the previous number of requests.
365 - poll_cb no longer returns number of requests.
366
3672.62 Sat Apr 26 13:59:33 CEST 2008
368 - port to solaris perls configured for old posix
369 (analysed by Jost Krieger).
370 - keep a reference to the perl filehandle object in aio_close,
371 so it doesn't get closed prematurely, leading to ugly races.
372
3732.61 Wed Apr 16 18:45:02 CEST 2008
374 - fix treescan output duplication and improve output ordering.
375 also display files given on the commandline.
376 - use a different algorithm for aio_close that is faster
377 and probably has even lower chances of blocking.
378 - do our own stack memory management for threads - linux
379 allocates outrageous amounts of VM (not so bad unless you
380 use mlockall...), which severely limits the number of threads
381 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
382 and 4096 * sizeof (long) (usually this is 16..64k).
383
3842.6 Sun Mar 30 08:28:11 CEST 2008
385 - added aio_sync.
386 - added aio_pathsync.
387 - fix prototypes of (void) functions.
388
3892.51 Sat Oct 6 16:04:54 CEST 2007
390 - perlio isn't generally threadsafe, so aio_close could not work reliably.
391 aio_close now tries a safe hack that might not be that asynchronous
392 (see the manpage for details).
393 - discard callback return values as to not grow the stack endlessly
394 when poll_cb handles many requests without returning.
395 - minor code cleanups.
396
3972.5 Thu Oct 4 14:49:08 CEST 2007
398 - replaced _fd2fh with faster xs code.
399 - aio_close will now try to do "the right thing" and thus might
400 work sensibly for the very first time.
401
4022.41 Mon Sep 24 21:28:21 CEST 2007
403 - after fork, invest some work to make sure that the poll_fileno
404 stays stable (by dup2'ing the new fd over the old one), to make
405 it easier for programs/libs that don't control their forking
406 behaviour and cannot recreate their watchers.
407
4082.4 Sun Aug 5 18:44:22 CEST 2007
409 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
410 successfully demonstrated that you can block on futimes...).
411 - allow undef as fileoffset for aio_read/write and use read/write(2)
412 internally (useful for sockets or O_APPEND handles).
413 - allow undef for length in aio_write.
414 - negative dataoffsets work as expected now in aio_read/aio_write.
415 - use NV instead of UV for 32 bit perls and file offsets, as NVs
416 have a larger range then.
417 - shared code between BDB and IO::AIO.
418 - aio_busy was completely broken. now fixed.
419 - readahead emulation now returns something.
420 - correctly set errno to ENOSYS on unimplemented functions
421 (should never happen, though).
422 - large changes to make it partially compile and run on win32,
423 but win32 lacks too much functionality, and perl overrides way
424 too many functions with crashing versions.
425
4262.33 Tue Jan 23 23:55:41 CET 2007
427 - fix install path (Andreas J. Koenig).
428
4292.32 Mon Jan 22 16:56:23 CET 2007
430 - added aio_rmtree.
431 - wow, aio_mkdir was missing.
432 - aio_load did return undef on error, not -1.
433 - use prefixexp not prefix in autoconf.pm
434 (suggested by ... rt.cpan.org unreachable).
435 - avoid installing autoconf.pm.
436
4372.31 Sat Jan 6 03:46:02 CET 2007
438 - added aio_load.
439
4402.3 Sat Dec 23 05:48:07 CET 2006
441 - fix off-by-one bug in aio_read, causing memory corruption
442 or crashes.
443
4442.21 Fri Dec 22 05:03:38 CET 2006
445 - minor doc updates.
446 - minor cleanups.
447 - IO::AIO::poll returns request count.
448 - undocumented and unfinished async-signal-reporting.
449
4502.2 Tue Oct 31 00:31:00 CET 2006
451 - minor doc updates.
452 - added aio_readlink.
453 - properly zero-terminate aio_read buffer.
454 - fix aio_read/write with nonzero dataoffset.
455 - reduced size of aio request structure.
456 - better diagnostics when pathnames etc. are not byte-encoded;
457 do not leak request in that case, either.
458
4592.1 Sun Oct 29 02:01:57 CET 2006
460 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
461 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
462 - fix a bug in aio_move where it would fail everytime
463 it would have to copy files manually.
464 - doc updates.
465 - start threads only on (very low) demand.
466 - end superfluous threads automatically after 10s idling.
467 - add IO::AIO::max_idle to control this.
468 - some tuning applied to random places.
469 - add aio_mknod.
470
4712.0 Thu Oct 26 18:27:58 CEST 2006
472 - minor incompatibility: max_outstanding semantics have changed.
473 - major rewrite, consider all functionality EXPERIMENTAL.
474 - aio requests can be cancelled.
475 - callbacks can be (re-)set later.
476 - aio requests can choose between 9 priorities.
477 - add aio_group: aio requests can be grouped
478 into composite requests.
479 - generator interface for groups.
480 - add IO::AIO::poll_some.
481 - major documentation improvements.
482 - very minor bugfixes.
483 - add aio_nop for dummy requests.
484 - add aio_busy mainly for benchmarking and debugging.
485 - use "fast" mutexes on linux.
486 - use dynamic (and larger) buffers instead of
487 putting them onto the stack.
488 - optimise x86 and amd64 a bit.
489 - better error checking when ENOMEM.
490 - hopefully fix mem and dirp leaks on fork.
491 - warn about broken perl malloc.
492 - compiles on cygwin (but pread is broken on cygwin
493 which is not detected by autoconf, so you have to
494 edit autoconf/config.h yourself to enable emulation).
495
4961.8 Sat Jun 24 22:20:44 CEST 2006
497 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
498
4991.73 Wed Mar 1 22:49:32 CET 2006
500 - codename "jost"
501 - AIX/Solaris(?) aren't being helpful again, hardcode a value
502 for NAME_MAX and drive with your eyes closed (reported by
503 wcooley@nakedape.cc).
504
5051.72 Thu Feb 2 00:40:44 CET 2006
506 - another minor bug in aio_scandir, again, the callback was called
507 twice when the directory can't be stat'ed.
508
5091.71 Mon Dec 26 20:20:03 CET 2005
510 - grr, another minor bug in aio_scandir, this time resulting
511 in a runtime error.
512
5131.7 Mon Dec 26 19:29:48 CET 2005
514 - aio_scandir errornously called callback twice in some cases.
515 - added AnyEvent example.
516
5171.61 Wed Sep 7 19:40:42 CEST 2005
518 - no longer include $Config{libs}, as distros include too much
519 garbage in there that is not installed on typical systems
520 (for example, debian links perl against -lgdbm and many more
521 libraries despite perl not needing it, slowing down startup and
522 wasting memory).
523
5241.6 Tue Aug 30 17:44:44 CEST 2005
525 - added aio_readdir, aio_scandir.
526 - added aio_sendfile, including sendfile emulation when sendfile
527 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
528 support is unavailable on my solaris 8 machine, but preliminary
529 code is there. What's lacking is configury stuff and testing...).
