4.51 Sun Aug 12 07:24:14 CEST 2018 |
41 |
- complete rework of the autoconf framework: IO::AIO now uses its own |
42 |
config.h, separate from libeio, and tries to test the actual perl |
43 |
environment, not the standard system environment. |
44 |
- provide nanosecond-accracy stat time accessors for both perl and IO::AIO |
45 |
stat functions. |
46 |
- removed non-portable C++ syntax from eio.c. |
47 |
- try to fix readdir tests on cygwin spuriously failing. |
48 |
|
49 |
4.5 Wed Aug 1 00:23:55 CEST 2018 |
50 |
- aio_mtouch touch all pages as requested, not just the first page in most cases. |
51 |
- new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE |
52 |
and MREMAP_FIXED. |
53 |
- add O_ACCMODE. |
54 |
- add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants. |
55 |
|
56 |
4.4 Tue Feb 20 07:54:12 CET 2018 |
57 |
- new aio_slurp request. |
58 |
- add (experimental) IO::AIO::eventfd and timerfd* function. |
59 |
- add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit. |
60 |
- point out that aio_copy overwrites existing files. |
61 |
- removed filesystem magic number table from aio_statvfs docs as |
62 |
statvfs doesn't actually return this info at all (statfs does). |
63 |
- add a bunch of (mostly linux-specific) constants for use in ioctls |
64 |
(see aio_ioctl docs). |
65 |
- treescan now has a proper manpage and useful --help output. |
66 |
- new option --sync in treescan, to sync everything in a subtree. |
67 |
- changed default for aio_msync flags to MSYNC_SYNC. |
68 |
- document offset/length behaviour of mprotect/madvise. |
69 |
- support linux's renameat2 (via aio_rename2). |
70 |
- add aio_rename2, an aio_rename with flags. |
71 |
- add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants. |
72 |

73 |
- (libeio) use posix_close if available. |
74 |
- (libeio) internal close() calls no longer disturb errno. |
75 |
- add IO:AIO::FALLOC_FL_UNSHARE. |
76 |
- update schmorp.h for removal of USE_SOCKETS_AS_HANDLES |
77 |
and better eventfd detection. |
78 |
|
79 |
4.34 Sun May 1 19:18:24 CEST 2016 |
80 |
- def0.h was not properly generated during previous release, causing |
81 |
compile errors on various platforms. |
82 |
- major/minor were accidentally switched (reported by Alexander Lishenyuk). |
83 |
- removed duplicate definition of MAP_HUGETLB, that was found due to |
84 |
a bug in Perl::Tidy (testcase by alaska332@gmail.com). |
85 |
- added (untested!) aio_fcntl, aio_ioctl requests. |
86 |
- (libeio) names set via prctl are truncated to 15 chars + nul, not 16, |
87 |
as manpages-dev originally claimed. |
88 |
|
89 |

- use NO_INIT where applicable. |
97 |
- update libecb. |
98 |

100 |
|
101 |
4.32 Wed Feb 11 20:32:11 CET 2015 |
102 |
- replace off_t by STRLEN where appropriate, should not result in |
103 |
user-visible changes. |
104 |
- update ecb.h for C11 compatibility. |
105 |
|
106 |
4.31 Tue Jun 3 03:29:27 CEST 2014 |
107 |
- work around more 5.20 bugs. backwards compatibility my ass. |
108 |
|
109 |
4.3 Fri Apr 11 06:22:38 CEST 2014 |
110 |
- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL |
111 |
without warning by switching the meaning of USE_SOCKETS_AS_HANDLES |
112 |
in 5.18. What's so attractive about giving a shit about backwards |
113 |
compatibility - I will never understand. |
114 |
|
115 |
4.2 Sat Jan 25 01:13:14 CET 2014 |
116 |
- aio_group could corrupt memory because it didn't restore |
117 |
the stack after req_submit. |

123 |
- (libecb) insignificant update. |
124 |
|
125 |
4.19 Sun Jan 6 12:47:26 CET 2013 |
126 |
- avoid endless loop in fiemap with some XFS files. |
127 |
- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."] |
128 |
and call rename/rmdir instead of renameat/unlinkat. |
129 |
|
130 |
4.18 Thu Oct 11 07:01:26 CEST 2012 |
131 |
- fix unintended xthread_create by intentionalising it :) |
132 |
|
133 |
4.17 Thu Oct 11 05:19:47 CEST 2012 |
134 |
- rename aio_fallocate to aio_allocate, to match documentation. |
135 |
- add list of linux fsid values to aio_statvfs docs. |
136 |
- work around a bug in btrfs' FIEMAP ioctl implementation. |
137 |
- work around AIX bug: statvfs.f_fsid is a struct, not unsigned long |
138 |
as per unix spec. |
139 |
|
140 |
4.16 Tue Aug 14 05:39:03 CEST 2012 |
141 |
- aio_statvfs was wromgly marked for wd emulation, causing |
142 |
it to malfunction for paths. |
143 |
- fix a crash in aio_fiemap, when used on ranges without any |
144 |
extents. |
145 |
- work around linux kernel bug (at least in 3.2): kernel might |
146 |
trash fiemap input arguments. |
147 |
- work around linux kernel bug (at least in 3.2): kernel does not |
148 |
set FIEMAP_EXTENT_LAST on last segment. |
149 |
- work around linux kernel bug (at least in 3.2): kernel silently |
150 |
truncates segment count if a file. |
151 |
- make fh argument of IO::AIO::mmap optional, also add mmap/munmap |
152 |
to quick overview. |
153 |
- splice can corrupt data. |
154 |
- (libeio) remove pread/pwrite emulation. |
155 |
- do not grow mmaped scalars in aio_read. |
156 |
- add FALLOC_FL_PUNCH_HOLE and document fallocate. |
157 |
- provide pread/pwrite for win32, making it link again on native win32. |
158 |
|
159 |
4.15 Tue Apr 10 06:59:00 CEST 2012 |
160 |
- always include linux/types.h for fiemap, for compatibility to |
161 |
ancient systems (Paul Howarth). |
162 |
- experimental support for IO::AIO::splice and ::tee (no aio_...). |
163 |
- provide SEEK_HOLE and SEEK_DATA, if available. |
164 |
- work around (again!) an immensely stupid bug in RHEL, defining |
165 |
autoconf macros in linux system headers (analysed by Paul Howarth). |
166 |
|
167 |
4.14 Sat Apr 7 02:45:18 CEST 2012 |
168 |
- fix stat structure usage on windows, which caused bogus stat results. |
169 |
- (libeio) make readahead emulation behave more like actual readahead by never failing. |
170 |
- new request aio_seek. |
171 |
- new request aio_fiemap. |

173 |
|
174 |
4.12 Fri Dec 30 08:51:25 CET 2011 |
175 |
- realpath would return a random value if the name was too long, |
176 |
instead of -1. |
177 |

178 |
|
179 |
4.11 Mon Oct 10 00:24:11 CEST 2011 |
180 |
- libeio didn't compile on !linux (Paul Howarth). |
181 |
|
182 |
4.1 Sun Oct 9 10:24:11 CEST 2011 |
183 |
- IO::AIO did access uninitialised memory on unsuccessful stats. |
184 |
- (libeio) added syncfs syscall wrapper. |
185 |
- (libeio) set thread name on linux (ps -L/Hcx, top, gdb). |
186 |
- (libeio) support multiple indepenent working directories. |
187 |
- applied speling corrections by Nicholas Bamber. |
188 |
- tune treescan #threads and #outstanding requests a bit. |
189 |
- reduce the number of file descriptors in use at any one time |
190 |
in treescan, to avoid running out of them (and using too much ram). |
191 |
- take advantage of working directoriy abstractions |
192 |
in aio_scandir and treescan. |
193 |
- reduce compiled size by ~10% by not inlining some key functionality. |
194 |
- added --progress switch to treescan. |
195 |
|
196 |
4.0 Mon Jul 18 05:01:10 CEST 2011 |
197 |
- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was), |
198 |
see FORK BEHAVIOUR in manpage for details. |
199 |
- passes testsuite on win32 now and may actually work |
200 |
(activestate 5.10.1 / MSVC6, YMMV). |
201 |
- (libeio) fix a deadlock where a wakeup signal could be missed when |
202 |
a timeout occured at the same time. |
203 |
- (libeio) added realpath. |
204 |
- (libeio) added fallocate. |
205 |
- (libeio) disabling sendfile on darwin unfortunately broke the emulation. |
206 |
- (libeio) do not acquire any locks when forking. |
207 |
- (libeio) use fewer time() syscalls when waiting for new requests. |
208 |
|
209 |
3.93 Wed Jun 29 23:44:18 CEST 2011 |
210 |
- ECB.H WAS MISSING. |
211 |
|
212 |
3.92 Wed Jun 29 14:45:41 CEST 2011 |
213 |
- ecb.h was missing. |
214 |
|
215 |
3.91 Wed Jun 29 13:24:42 CEST 2011 |
216 |
- (libeio) work around a Linux (and likely FreeBSD and other |
217 |
kernels) bug where sendfile would not transfer all the requested |
218 |
bytes on large transfers, using a heuristic. |
219 |
- buggy sendfile caused aio_move/copy to sometimes fail for big |
220 |
files (fortunately it checks that the whole file has been |
221 |
transferred...) |
222 |
- use libecb for higher performance and higher portability. |
223 |
- (libeio) disable sendfile on darwin, it's too broken. |
224 |
- disable fork tests on !linux, as only linux supports mixing |
225 |
pthread and fork in perl. |
226 |
- document the fact that fork doesn't work anymore when using |
227 |
this module, on anything !GNU/Linux. |
228 |
- increase timeout in t/04_fork.t, as too many CPAN-tester setups |
229 |
run on a 0.1MHz cpu. Or so. |
230 |
|
231 |
3.9 Fri May 27 02:43:47 CEST 2011 |
232 |
- (libeio) fix memory corruption in aio_readdirx for the flags |
233 |
combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST. |
234 |
- add lots of newer POSIX and GNU/Linux-specific open |
235 |
flags. |
236 |
|
237 |
3.8 Sun Mar 27 12:25:33 CEST 2011 |
238 |
- use nonstandard but maybe-working-on-bsd fork technique. |
239 |
- support a max_idle value of 0. |
240 |
- support setting of idle timeout value (IO::AIO::idle_timeout). |
241 |
|
242 |
3.72 Fri Feb 11 04:25:38 CET 2011 |
243 |
- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock. |
244 |
- aio_mknod always used a dev_t value of 0. |
245 |
- new treescan option: --grep. |
246 |
- add more S_IF macros, and major/minor/makedev "macros". |
247 |
|
248 |
3.71 Thu Dec 30 08:18:46 CET 2010 |
249 |
- the numerical result value passed to callbacks did not stringify |
250 |
correctly, due to internal reuse and failure to reset the sv flags. |
251 |
- actually test for posix_[mf]advise, as at least uClibc defines |
252 |
_POSIX_ADVISORY_INFO without actually having any of the required |
253 |
funcitonality. ugh. |
254 |
|
255 |
3.7 Mon Nov 1 23:00:34 CET 2010 |
256 |
- implement/add madvise, mmap, munmap, aio_mlockall, munlockall, |
257 |
aio_mlock, munlock, msync and mtouch to @EXPORT_OK. |
258 |
- document the sad state of affairs w.r.t. pthread on many bsds. |
259 |
- do not enable mmap on systems without _POSIX_MAPPED_FILES |
260 |
(openbsd 4.8). |
261 |
- do not leak memory in IO::AIO::mmap when the scalar already |
262 |
had string-data. |
263 |
- add O_RDWR, O_APPEND and O_EXCL symbols and semi-document |
264 |
them. |
265 |
- cache the result IV, for a minor speedup in the common case. |
266 |
- croak when an mmapped-scalar changes location, to detect |
267 |
user-errors better. |
268 |
- fix aio_readlink prototype. |
269 |
|
270 |
3.65 Wed Mar 31 02:45:05 CEST 2010 |
271 |
- actually use PATH_MAX instead of NAME_MAX for readlink, as to not |
272 |
cut off long pathnames in aio_readlink (based on patch by |
273 |
Rasmus Andersson). |
274 |
- a double fork partially killed the event pipe (great testcase |
275 |
by dormando). affects IO::AIO, BDB and Async::Interrupt. |
276 |
- suck steve's dick and rename our symbols to avoid colliding |
277 |
with nonstandard identifier spam on the broken os x pseudo-os. |
278 |
affects IO::AIO and BDB. |
279 |
|
280 |
3.6 Mon Jan 11 00:43:39 CET 2010 |
281 |
- (libeio) more fixes for the freebsd/apple sendfile - broken by |
282 |
manpage standards, but apparently correct accoridng to actual |
283 |
kernel sources. |
284 |
- add IO::AIO::mmap/munmap support. |
285 |
- add IO::AIO::m(un)lockall support. |
286 |
- clean up manpage. |
287 |
|
288 |
3.5 Thu Jan 7 21:25:04 CET 2010 |
289 |
- (liebio) fix freebsd sendfile (Vanilla Hsu). |
290 |
- (libeio) also fix darwin sendfile that suffered from a similar bug. |
291 |
- add aio_statvfs as interface to statvfs/fstatvfs. |
292 |
- work around buggy symlink() on cygwin in the testsuite. |
293 |
- wtf. freebsd-8.0 actually passes the testsuite! I knew |
294 |
they could implement fork and semaphores one day! cheers! |
295 |
|
296 |
3.4 Sat Jan 2 15:13:04 CET 2010 |
297 |
- (libeio) max_poll_time was not properly converted to ticks. |
298 |
- clarify cancel_subs description. |
299 |
- IO::AIO::sendfile did not actually return the return value |
300 |
from the sendfile call. |
301 |
- implement aio_msync, aio_mtouch. |
302 |
- (libeio) tentatively support darwin in sendfile. |
303 |
|
304 |
3.31 Thu Nov 12 02:14:29 CET 2009 |
305 |
- fix result status documentation of aio_copy, aio_move. |
306 |
- speed up object creation considerably by avoiding |
307 |
hash lookups. |
308 |
|
309 |
3.3 Wed Aug 5 13:52:58 CEST 2009 |
310 |
- use common::sense. |
311 |
- use common schmorp.h header. |
312 |
- allow integers (file descriptors) in addition to file handles. |
313 |
- take advantage of linux' eventfd (but it seems slower on smp?). |
314 |
- use poll not select on posix platforms. |
315 |
|
316 |
3.261 Wed Jul 1 10:11:51 CEST 2009 |
317 |
- more 0S X workarounds (patch by Tokuhiro Matsuno). |
318 |
|
319 |
3.26 Tue Jun 30 09:33:26 CEST 2009 |
320 |
- 0S X of course claims to be posix 2008 but lacks posix_fadvise. |
321 |
try to work around this horribly broken OS in a somewhat hackish |
322 |
way. might help other os's too. |
323 |
|
324 |
3.25 Sat Jun 27 05:18:26 CEST 2009 |
325 |
- added IO::AIO::fadvise and IO::AIO::sendfile. |
326 |
- (libeio) replaced quicksort+insertion sort by a tuned radix |
327 |
sort + insertion sort, resulting in comparable runtime (usually |
328 |
faster) to the old version, but without any ill side effects on |
329 |
degenerated (for quicksort) data. |
330 |
- (libeio) correctly sort dirs by inodes if we have perfect type |
331 |
knowledge and DIRS_FIRST is used. |
332 |
- (libeio) internally the wrong DT_* constants were used, but no |
333 |
known system has differing EIO_DT_*/DT_* values, so not an issue. |
334 |
- removed a (harmless) assert that was left over on the code |
335 |
but should not have been. |
336 |
- use more correct types (change IO length from IV to VAL64, |
337 |
which makes a difference on systems without 64 bit perls). |
338 |
|
339 |
3.23 Sat Jun 13 16:57:58 CEST 2009 |
340 |
- fix off-by-one bug in aio_readdir that was introduced in the |
341 |
rushed 3.22 release. |
342 |
|
343 |
3.22 Sat Jun 13 15:32:40 CEST 2009 |
344 |
- speed up readdirx sort algorithm slightly. |
345 |
- bin/treescan was missing from distro tarball. |
346 |
|
347 |
3.21 Fri Jun 12 18:45:53 CEST 2009 |
348 |
- new options --dirs and --files for treescan. |
349 |
- install bin/treescan by default. |
350 |
- (libeio) aio_readdir can now be cancelled while executing. |
351 |
- fix a printf format string for 64 bit systems (could lead |
352 |
to problems on big endian 64 bit systems). |
353 |
- do not use qsort() but our own algorithm: glibc initialises |
354 |
the whole locale and I/O subsystem inside qsort, causing |
355 |
a stack overflow on 32 bit machines. The new sort uses much less |
356 |
stack and is more than twice as fast in typical situations. |
357 |
|
358 |
3.2 Sun Jun 7 20:30:05 CEST 2009 |
359 |
- (libeio) pwrite emulation was even more flawed than intended and did |
360 |
not restore the file offset. |
361 |
- add aio_readdirx, which can return inode and filetype and sort |
362 |
the names in various ways. |
363 |
- unfortunately, utime, chmod, chown on an open file that has just |
364 |
been written can easily block, which caused aio_copy to block the |
365 |
process. no more! |
366 |
- no longer rely on dst path in aio_copy when futime is available. |
367 |
|
368 |
3.19 Tue Apr 21 22:05:21 CEST 2009 |
369 |
- more perl 5.10 workarounds for aio_read and write. |
370 |
- aio_write no longer modifies the sv (if possible). |
371 |
- aio_read now works correctly with magic values. |
372 |
|
373 |
3.18 Sun Apr 19 21:17:32 CEST 2009 |
374 |
- better diagnostics when some aio_* functions get passed an illegal fh. |
375 |
- try to avoid crashes due to incompatible 5.10 API changes. grmbl. |
376 |
|
377 |
3.17 Thu Nov 20 08:45:36 CET 2008 |
378 |
- (libeio) added aio_sync_file_range (untested). |
379 |
- add aio_busy to @IO::AIO::AIO_REQ. |
380 |
|
381 |
3.16 Wed Oct 22 18:28:01 CEST 2008 |
382 |
- use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical |
383 |
part to improve portability to perl 5.8 (reported by szymon). |
384 |
|
385 |
3.15 Mon Oct 13 00:39:55 CEST 2008 |
386 |
- automatic removal of feeders was broken. |
387 |
- (libeio) use a more robust method to detect whether a feeder |
388 |
has added something to the group or not. |
389 |
|
390 |
3.1 Thu Oct 2 13:34:40 CEST 2008 |
391 |
- pre-deref the passed callback object, for increased speed |
392 |
and decreased memory usage. |
393 |
- call on_next_submit callback even for aio_group - impact unknown, |
394 |
but seems more correct. |
395 |
- $req->cb now returns the original callback. |
396 |
- (libeio) pass EIO_GROUP/aio_group requests through the queue without |
397 |
requiring a thread switch. |
398 |
- (libeio) status code of aio_futime and aio_utime was always passed 0. |
399 |
- do some other µ-optimisations. |
400 |
|
401 |
3.07 Sat Aug 2 16:06:13 CEST 2008 |
402 |
- do not include LIBS in autoconf tests. |
403 |
|
404 |
3.06 Tue Jul 15 12:41:32 CEST 2008 |
405 |
- move preadwritelock definition before it's first reference, |
406 |
to make it compile again on broken platforms (they still exist) |
407 |
or badly cofngiured perls (redhat...), reported by Rob Bloodgood. |
408 |
|
409 |
3.05 Thu Jun 19 23:23:52 CEST 2008 |
410 |
- work around perl overriding readdir etc. with thread-unsafe |
411 |
(sic!) versions. |
412 |
|
413 |
3.04 Wed Jun 18 01:35:38 CEST 2008 |
414 |
- (libeio) fix eio_mknod, which confused it's arguments. |
415 |
- (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this |
416 |
is stupid. |
417 |
- (libeio) fix eio__readahead prototype, patch by Jost Krieger. |
418 |
- (libeio) fix a bug that could potentially cause IO::AIO |
419 |
not to get initialised properly. |
420 |
|
421 |
3.03 Thu May 29 05:33:30 CEST 2008 |
422 |
- (libeio) correctly call pthread_attr_destroy (). |
423 |
- (libeio) work around broken bsd headers once more. |
424 |
- reduce shared library size again by not including wrappers. |
425 |
- max_outstanding could cause poll to enter a busy-waiting loop. |
426 |
- document the new IO::AIO::poll_cb result value. |
427 |
|
428 |
3.02 Mon May 12 02:32:02 CEST 2008 |
429 |
- fix a memory leak on aio_readlink. |
430 |
- bring back working fchmod. |
431 |
- nop and busy now set result to 0. |
432 |
- set errno to ENOMEM when allocation fails. |
433 |
|
434 |
3.01 Sun May 11 03:07:03 CEST 2008 |
435 |
- (libeio) make it compile on systems without readahead or readdir_r. |
436 |
- (libeio) improve configure check for readahead availability. |
437 |
- do not try to link against -lrt. |
438 |
- use a separate configure script for IO::AIO (not the libeio one). |
439 |
|
440 |
3.0 Sun May 11 00:57:14 CEST 2008 |
441 |
- added bin/treescan to the distribution. |
442 |
- switched to using libeio. |
443 |
- LOTS OF INCOMPATIBLE CHANGES: |
444 |
- remove signal functionality, it is not worth the effort. |
445 |
- max_outstanding no longer returns the previous number of requests. |
446 |
- poll_cb no longer returns number of requests. |
447 |
|
448 |
2.62 Sat Apr 26 13:59:33 CEST 2008 |
449 |
- port to solaris perls configured for old posix |
450 |
(analysed by Jost Krieger). |
451 |
- keep a reference to the perl filehandle object in aio_close, |
452 |
so it doesn't get closed prematurely, leading to ugly races. |
453 |
|
454 |
2.61 Wed Apr 16 18:45:02 CEST 2008 |
455 |
- fix treescan output duplication and improve output ordering. |
456 |
also display files given on the commandline. |
457 |
- use a different algorithm for aio_close that is faster |
458 |
and probably has even lower chances of blocking. |
459 |
- do our own stack memory management for threads - linux |
460 |
allocates outrageous amounts of VM (not so bad unless you |
461 |
use mlockall...), which severely limits the number of threads |
462 |
on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN |
463 |
and 4096 * sizeof (long) (usually this is 16..64k). |
464 |
|
465 |
2.6 Sun Mar 30 08:28:11 CEST 2008 |
466 |
- added aio_sync. |
467 |
- added aio_pathsync. |
468 |
- fix prototypes of (void) functions. |
469 |
|
470 |
2.51 Sat Oct 6 16:04:54 CEST 2007 |
471 |
- perlio isn't generally threadsafe, so aio_close could not work reliably. |
472 |
aio_close now tries a safe hack that might not be that asynchronous |
473 |
(see the manpage for details). |
474 |
- discard callback return values as to not grow the stack endlessly |
475 |
when poll_cb handles many requests without returning. |
476 |
- minor code cleanups. |
477 |
|
478 |
2.5 Thu Oct 4 14:49:08 CEST 2007 |
479 |
- replaced _fd2fh with faster xs code. |
480 |
- aio_close will now try to do "the right thing" and thus might |
481 |
work sensibly for the very first time. |
482 |
|
483 |
2.41 Mon Sep 24 21:28:21 CEST 2007 |
484 |
- after fork, invest some work to make sure that the poll_fileno |
485 |
stays stable (by dup2'ing the new fd over the old one), to make |
486 |
it easier for programs/libs that don't control their forking |
487 |
behaviour and cannot recreate their watchers. |
488 |
|
489 |
2.4 Sun Aug 5 18:44:22 CEST 2007 |
490 |
- add aio_truncate, aio_chmod, aio_chown, aio_utime (linux |
491 |
successfully demonstrated that you can block on futimes...). |
492 |
- allow undef as fileoffset for aio_read/write and use read/write(2) |
493 |
internally (useful for sockets or O_APPEND handles). |
494 |
- allow undef for length in aio_write. |
495 |
- negative dataoffsets work as expected now in aio_read/aio_write. |
496 |
- use NV instead of UV for 32 bit perls and file offsets, as NVs |
497 |
have a larger range then. |
498 |
- shared code between BDB and IO::AIO. |
499 |
- aio_busy was completely broken. now fixed. |
500 |
- readahead emulation now returns something. |
501 |
- correctly set errno to ENOSYS on unimplemented functions |
502 |
(should never happen, though). |
503 |
- large changes to make it partially compile and run on win32, |
504 |
but win32 lacks too much functionality, and perl overrides way |
505 |
too many functions with crashing versions. |
506 |
|
507 |
2.33 Tue Jan 23 23:55:41 CET 2007 |
508 |
- fix install path (Andreas J. Koenig). |
509 |
|
510 |
2.32 Mon Jan 22 16:56:23 CET 2007 |
511 |
- added aio_rmtree. |
512 |
- wow, aio_mkdir was missing. |
513 |
- aio_load did return undef on error, not -1. |
514 |
- use prefixexp not prefix in autoconf.pm |
515 |
(suggested by ... rt.cpan.org unreachable). |
516 |
- avoid installing autoconf.pm. |
517 |
|
518 |
2.31 Sat Jan 6 03:46:02 CET 2007 |
519 |
- added aio_load. |
520 |
|
521 |
2.3 Sat Dec 23 05:48:07 CET 2006 |
522 |
- fix off-by-one bug in aio_read, causing memory corruption |
523 |
or crashes. |
524 |
|
525 |
2.21 Fri Dec 22 05:03:38 CET 2006 |
526 |
- minor doc updates. |
527 |
- minor cleanups. |
528 |
- IO::AIO::poll returns request count. |
529 |
- undocumented and unfinished async-signal-reporting. |
530 |
|
531 |
2.2 Tue Oct 31 00:31:00 CET 2006 |
532 |
- minor doc updates. |
533 |
- added aio_readlink. |
534 |
- properly zero-terminate aio_read buffer. |
535 |
- fix aio_read/write with nonzero dataoffset. |
536 |
- reduced size of aio request structure. |
537 |
- better diagnostics when pathnames etc. are not byte-encoded; |
538 |
do not leak request in that case, either. |
539 |
|
540 |
2.1 Sun Oct 29 02:01:57 CET 2006 |
541 |
- INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by |
542 |
IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. |
543 |
- fix a bug in aio_move where it would fail everytime |
544 |
it would have to copy files manually. |
545 |
- doc updates. |
546 |
- start threads only on (very low) demand. |
547 |
- end superfluous threads automatically after 10s idling. |
548 |
- add IO::AIO::max_idle to control this. |
549 |
- some tuning applied to random places. |
550 |
- add aio_mknod. |
551 |
|
552 |
2.0 Thu Oct 26 18:27:58 CEST 2006 |
553 |
- minor incompatibility: max_outstanding semantics have changed. |
554 |
- major rewrite, consider all functionality EXPERIMENTAL. |
555 |
- aio requests can be cancelled. |
556 |
- callbacks can be (re-)set later. |
557 |
- aio requests can choose between 9 priorities. |
558 |
- add aio_group: aio requests can be grouped |
559 |
into composite requests. |
560 |
- generator interface for groups. |
561 |
- add IO::AIO::poll_some. |
562 |
- major documentation improvements. |
563 |
- very minor bugfixes. |
564 |
- add aio_nop for dummy requests. |
565 |
- add aio_busy mainly for benchmarking and debugging. |
566 |
- use "fast" mutexes on linux. |
567 |
- use dynamic (and larger) buffers instead of |
568 |
putting them onto the stack. |
569 |
- optimise x86 and amd64 a bit. |
570 |
- better error checking when ENOMEM. |
571 |
- hopefully fix mem and dirp leaks on fork. |
572 |
- warn about broken perl malloc. |
573 |
- compiles on cygwin (but pread is broken on cygwin |
574 |
which is not detected by autoconf, so you have to |
575 |
edit autoconf/config.h yourself to enable emulation). |
576 |
|
577 |
1.8 Sat Jun 24 22:20:44 CEST 2006 |
578 |
- add and/or document aio_rename, aio_link, aio_symlink and aio_move. |
579 |
|
580 |
1.73 Wed Mar 1 22:49:32 CET 2006 |
581 |
- codename "jost" |
582 |
- AIX/Solaris(?) aren't being helpful again, hardcode a value |
583 |
for NAME_MAX and drive with your eyes closed (reported by |
584 |
wcooley@nakedape.cc). |
585 |
|
586 |
1.72 Thu Feb 2 00:40:44 CET 2006 |
587 |
- another minor bug in aio_scandir, again, the callback was called |
588 |
twice when the directory can't be stat'ed. |
589 |
|
590 |
1.71 Mon Dec 26 20:20:03 CET 2005 |
591 |
- grr, another minor bug in aio_scandir, this time resulting |
592 |
in a runtime error. |
593 |
|
594 |
1.7 Mon Dec 26 19:29:48 CET 2005 |
595 |
- aio_scandir errornously called callback twice in some cases. |
596 |
- added AnyEvent example. |
597 |
|
598 |
1.61 Wed Sep 7 19:40:42 CEST 2005 |
599 |
- no longer include $Config{libs}, as distros include too much |
600 |
garbage in there that is not installed on typical systems |
601 |
(for example, debian links perl against -lgdbm and many more |
602 |
libraries despite perl not needing it, slowing down startup and |
603 |
wasting memory). |
604 |
|
605 |
1.6 Tue Aug 30 17:44:44 CEST 2005 |
606 |
- added aio_readdir, aio_scandir. |
607 |
- added aio_sendfile, including sendfile emulation when sendfile |
608 |
isn't available. Linux, FreeBSD and HP-UX might work (sendfilev |
609 |
support is unavailable on my solaris 8 machine, but preliminary |
610 |
code is there. What's lacking is configury stuff and testing...). |
611 |
|
612 |
1.5 Sat Aug 20 02:32:19 CEST 2005 |
613 |
- create the aio threads on demand only (good after forking). |
614 |
- somebody nagged about C89 compatibility, so this release should |
615 |
be C89 compatible, but no guarantees for future ones. |
616 |
- abort when the configure script fails. |
617 |
|
618 |
1.4 Wed Aug 17 08:07:27 CEST 2005 |
619 |
- forgot to recreate the pipe after forking, this could cause |
620 |
deadlocks. |
621 |
|
622 |
1.3 Wed Aug 17 07:25:54 CEST 2005 |
623 |
- properly propagate exceptions from callbacks, instead of silently |
624 |
eating them. |
625 |
- use a different fork algorithm that avoids recursive callback |
626 |
invocations and reduces fork latency in busy processes. |
627 |
- fix a bug where the buffer scalar in aio_read got assigned the wrong |
628 |
length after reading. |
629 |
- fix a bug where the child would process some outstanding requests |
630 |
from the parent. |
631 |
- make a copy of the callback scalar, to avoid some very uncommon |
632 |
(but valid) usages where the callback scalar changes. |
633 |
- the callback was never freed in aio_read/aio_write. |
634 |
- aio_read/aio_write will now set the readonly flag on the data |
635 |
scalar for better error reporting. |
636 |
|
637 |
1.2 Wed Aug 17 01:22:58 CEST 2005 |
638 |
- verified on cygwin, linux/amd64+ia32+alpha, solaris. |
639 |
- use SvPVbyte for filenames now. You *need* to encode your strings to |
640 |
the external filename encoding first. |
641 |
- fix the bug where filehandles could leak (again). |
642 |
- clarify freebsd situation: make it work and tell me how, or go away |
643 |
with your underdocumented, broken and outdated OS. |
644 |
- fork'ing should now be officially supported (where linux and |
645 |
posix contradict each other, I followed posix). |
646 |
- only call read() once per poll, not twice (speedup). |
647 |
- new functions: aio_rmdir, aio_symlink. |
648 |
- force callback arguments to be undef or a reference, for better |
649 |
error catching. |
650 |
|
651 |
1.1 Sun Aug 7 05:27:23 CEST 2005 |
652 |
- added configure script to detect availability of some calls. |
653 |
(imperfect, as we cannot detect things like -lrt due to missing |
654 |
feedback yet). |
655 |
- emulate fdatasync via fsync, pread/pwrite via unsafe read/write |
656 |
and readahead via manual reading on platforms lacking those. |
657 |
- ported t/03_errors.t+framework by Brad Fitzpatrick |
658 |
from Linux::AIO. |
659 |
- removed XOPEN_SOURCE because stupid solaris 9 doesn't |
660 |
compile with it enabled. Probably breaks others. Oh well. |
661 |
- try to be more careful with errno on non-threaded perls. |
662 |
- cygwins perl insisted on a matching open mode when morphing |
663 |
the fd to an fh. |
664 |
- convert sv's to "byte" encoding in aio_read/aio_write. Might |
665 |
do that for pathnames, too, in the future, so make sure you |
666 |
properly encode your pathnames. |
667 |
|
668 |
1.0 Fri Jul 22 10:43:30 CEST 2005 |
669 |
- aio_open did not reliably deliver (open) filehandles. |
670 |
- all aio_*-functions keep a reference to the filehandle so |
671 |
it doesn't go away while the aio requests is working on it. |
672 |
- disable warnings in AIO.pm. |
673 |
|
674 |
0.9 Wed Jul 20 23:55:04 CEST 2005 |
675 |
- allow recursive calls to poll_cb, use less locking calls, too. |
676 |
- fix the Gtk2-example in the SYNOPSIS. |
677 |
- use pread/pwrite not pread64/pwrite64. this was simply a leftover |
678 |
from Linux::AIO. |
679 |
(found by compiling on cygwin. Unfortunately, cygwin declares but |
680 |
does not implement pread/pwrite). |
681 |
- only include <sys/syscall.h> on linux. |
682 |
|
683 |
0.5 Tue Jul 12 13:03:09 CEST 2005 |
684 |
- removed #include <endian.h>, it's not portable, and we don't |
685 |
need it anyway. |
686 |
- link against -lrt, as it might contain goodies such as fdatasync, |
687 |
and often aio_read, which we do not use yet, but it shouldn't hurt. |
688 |
|
689 |
0.4 Mon Jul 11 05:28:25 CEST 2005 |
690 |
- added IO::AIO::flush, IO::AIO::poll. |
691 |
- make callback argument optional for all calls. |
692 |
|
693 |
0.3 Mon Jul 11 01:42:37 CEST 2005 |
694 |
- restructured manpage. |
695 |
- added SYNOPSIS with examples for Event, Glib, Tk. |
696 |
- remove explicit context support so I don't have to maintain |
697 |
it for threaded perls (i.e. it should work now :). |
698 |
|
699 |
0.2 Sun Jul 10 22:57:12 CEST 2005 |
700 |
- return immediately from poll_wait if nreqs==0. |
701 |
- get rid of the request pipe and use faster thread-thread |
702 |
communications for most requests and responses. |
703 |
|
704 |
0.1 |
705 |
- cloned from Linux::AIO, which is very similar. |
706 |
|
