|
|
51 | - point out that aio_copy overwrites existing files. |
|
|
52 | - removed filesystem magic number table from aio_statvfs docs as |
|
|
53 | statvfs doesn't actually return this info at all (statfs does). |
|
|
54 | - add a bunch of (mostly linux-specific) constants for use in ioctls |
|
|
55 | (see aio_ioctl docs). |
|
|

|
|
70 | 4.34 Sun May 1 19:18:24 CEST 2016 |
|
|
71 | - def0.h was not properly generated during previous release, causing |
|
|
72 | compile errors on various platforms. |
|
|
73 | - major/minor were accidentally switched (reported by Alexander Lishenyuk). |
|
|
74 | - removed duplicate definition of MAP_HUGETLB, that was found due to |
|
|
75 | a bug in Perl::Tidy (testcase by alaska332@gmail.com). |

|
76 | - added (untested!) aio_fcntl, aio_ioctl requests. |
|
|
77 | - (libeio) names set via prctl are truncated to 15 chars + nul, not 16, |
|

|
|
85 | - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK |
|
|
86 | consdtants, whether they can be sensibly used or not. |
|

|
98 | - work around more 5.20 bugs. backwards compatibility my ass. |
|
|
99 | |
|
|
100 | 4.3 Fri Apr 11 06:22:38 CEST 2014 |
|
|
101 | - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL |
|
|
102 | without warning by switching the meaning of USE_SOCKETS_AS_HANDLES |
|
|
103 | in 5.18. What's so attractive about giving a shit about backwards |
|
|
104 | compatibility - I will never understand. |
|
|
105 | |
|
|
106 | 4.2 Sat Jan 25 01:13:14 CET 2014 |
|
|
107 | - aio_group could corrupt memory because it didn't restore |

|
117 | - avoid endless loop in fiemap with some XFS files. |
|
|
118 | - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."] |
|
|
119 | and call rename/rmdir instead of renameat/unlinkat. |

|
|
129 | as per unix spec. |
|
|
130 | |
|
|
131 | 4.16 Tue Aug 14 05:39:03 CEST 2012 |
|
|
132 | - aio_statvfs was wromgly marked for wd emulation, causing |
|
|
133 | it to malfunction for paths. |
|
|
134 | - fix a crash in aio_fiemap, when used on ranges without any |
|
|
135 | extents. |
|
|
136 | - work around linux kernel bug (at least in 3.2): kernel might |
|
|
137 | trash fiemap input arguments. |
|
|
138 | - work around linux kernel bug (at least in 3.2): kernel does not |
|
|
139 | set FIEMAP_EXTENT_LAST on last segment. |
|
|
140 | - work around linux kernel bug (at least in 3.2): kernel silently |
|
|
141 | truncates segment count if a file. |
|
|
142 | - make fh argument of IO::AIO::mmap optional, also add mmap/munmap |
|
|
143 | to quick overview. |

|
|
150 | 4.15 Tue Apr 10 06:59:00 CEST 2012 |
|
|
151 | - always include linux/types.h for fiemap, for compatibility to |
|
|
152 | ancient systems (Paul Howarth). |
|
|
153 | - experimental support for IO::AIO::splice and ::tee (no aio_...). |
|
|
154 | - provide SEEK_HOLE and SEEK_DATA, if available. |
|
|
155 | - work around (again!) an immensely stupid bug in RHEL, defining |
|
|
156 | autoconf macros in linux system headers (analysed by Paul Howarth). |
|
|
157 | |
|
|
158 | 4.14 Sat Apr 7 02:45:18 CEST 2012 |
|
|
159 | - fix stat structure usage on windows, which caused bogus stat results. |
|
|

164 | |
|
|
165 | 4.12 Fri Dec 30 08:51:25 CET 2011 |
|
|
166 | - realpath would return a random value if the name was too long, |
|
|
167 | instead of -1. |
|
|
168 | - port to c89. |
|
|
169 | |
|
|
170 | 4.11 Mon Oct 10 00:24:11 CEST 2011 |
|
|
171 | - libeio didn't compile on !linux (Paul Howarth). |

|
|
173 | 4.1 Sun Oct 9 10:24:11 CEST 2011 |
|
|
174 | - IO::AIO did access uninitialised memory on unsuccessful stats. |
|
|
175 | - (libeio) added syncfs syscall wrapper. |
|
|
176 | - (libeio) set thread name on linux (ps -L/Hcx, top, gdb). |
|
|
177 | - (libeio) support multiple indepenent working directories. |
|
|
178 | - applied speling corrections by Nicholas Bamber. |
|
|
179 | - tune treescan #threads and #outstanding requests a bit. |
|
|
180 | - reduce the number of file descriptors in use at any one time |
|
|
181 | in treescan, to avoid running out of them (and using too much ram). |
|
|
182 | - take advantage of working directoriy abstractions |
|
|
183 | in aio_scandir and treescan. |
|
|
184 | - reduce compiled size by ~10% by not inlining some key functionality. |
|
|
185 | - added --progress switch to treescan. |
|
|
186 | |
|
|
187 | 4.0 Mon Jul 18 05:01:10 CEST 2011 |
|
|
188 | - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was), |
|
|
189 | see FORK BEHAVIOUR in manpage for details. |
|
|
190 | - passes testsuite on win32 now and may actually work |
|
|
191 | (activestate 5.10.1 / MSVC6, YMMV). |
|
|
192 | - (libeio) fix a deadlock where a wakeup signal could be missed when |
|
|
193 | a timeout occured at the same time. |
|
|
194 | - (libeio) added realpath. |
|
|

|
|
197 | - (libeio) do not acquire any locks when forking. |

|
200 | 3.93 Wed Jun 29 23:44:18 CEST 2011 |
|
|
201 | - ECB.H WAS MISSING. |
|
|
202 | |
|
|
203 | 3.92 Wed Jun 29 14:45:41 CEST 2011 |
|
|
204 | - ecb.h was missing. |
|
|
205 | |
|
|
206 | 3.91 Wed Jun 29 13:24:42 CEST 2011 |
|
|
207 | - (libeio) work around a Linux (and likely FreeBSD and other |
|
|
208 | kernels) bug where sendfile would not transfer all the requested |
|
|
209 | bytes on large transfers, using a heuristic. |
|
|
210 | - buggy sendfile caused aio_move/copy to sometimes fail for big |
|
|
211 | files (fortunately it checks that the whole file has been |
|
|
212 | transferred...) |
|
|
213 | - use libecb for higher performance and higher portability. |
|
|
214 | - (libeio) disable sendfile on darwin, it's too broken. |
|
|
215 | - disable fork tests on !linux, as only linux supports mixing |
|
|
216 | pthread and fork in perl. |
|
|
217 | - document the fact that fork doesn't work anymore when using |
|
|
218 | this module, on anything !GNU/Linux. |
|
|
219 | - increase timeout in t/04_fork.t, as too many CPAN-tester setups |
|
|
220 | run on a 0.1MHz cpu. Or so. |
|
|
221 | |
|
|
222 | 3.9 Fri May 27 02:43:47 CEST 2011 |
|
|
223 | - (libeio) fix memory corruption in aio_readdirx for the flags |
|
|
224 | combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST. |
|
|
225 | - add lots of newer POSIX and GNU/Linux-specific open |
|
|
226 | flags. |
|
|
227 | |
|
|
228 | 3.8 Sun Mar 27 12:25:33 CEST 2011 |
|
|
229 | - use nonstandard but maybe-working-on-bsd fork technique. |
|
|
230 | - support a max_idle value of 0. |
|
|
231 | - support setting of idle timeout value (IO::AIO::idle_timeout). |
|
|
232 | |
|
|
233 | 3.72 Fri Feb 11 04:25:38 CET 2011 |
|
|
234 | - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock. |
|
|
235 | - aio_mknod always used a dev_t value of 0. |
|
|
236 | - new treescan option: --grep. |
|
|
237 | - add more S_IF macros, and major/minor/makedev "macros". |
|
|
238 | |
|
|
239 | 3.71 Thu Dec 30 08:18:46 CET 2010 |
|
|
240 | - the numerical result value passed to callbacks did not stringify |
|
|
241 | correctly, due to internal reuse and failure to reset the sv flags. |
|
|
242 | - actually test for posix_[mf]advise, as at least uClibc defines |
|
|
243 | _POSIX_ADVISORY_INFO without actually having any of the required |
|
|
244 | funcitonality. ugh. |
|
|
245 | |
|
|
246 | 3.7 Mon Nov 1 23:00:34 CET 2010 |
|
|
247 | - implement/add madvise, mmap, munmap, aio_mlockall, munlockall, |
|
|
248 | aio_mlock, munlock, msync and mtouch to @EXPORT_OK. |
|
|
249 | - document the sad state of affairs w.r.t. pthread on many bsds. |
|
|
250 | - do not enable mmap on systems without _POSIX_MAPPED_FILES |
|
|
251 | (openbsd 4.8). |
|
|
252 | - do not leak memory in IO::AIO::mmap when the scalar already |
|
|
253 | had string-data. |
|
|
254 | - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document |
|
|
255 | them. |
|
|
256 | - cache the result IV, for a minor speedup in the common case. |
|
|
257 | - croak when an mmapped-scalar changes location, to detect |
|
|
258 | user-errors better. |
|
|
259 | - fix aio_readlink prototype. |
|
|
260 | |
|
|
261 | 3.65 Wed Mar 31 02:45:05 CEST 2010 |
|
|
262 | - actually use PATH_MAX instead of NAME_MAX for readlink, as to not |
|
|
263 | cut off long pathnames in aio_readlink (based on patch by |
|
|
264 | Rasmus Andersson). |
|
|
265 | - a double fork partially killed the event pipe (great testcase |
|
|
266 | by dormando). affects IO::AIO, BDB and Async::Interrupt. |
|
|
267 | - suck steve's dick and rename our symbols to avoid colliding |
|
|
268 | with nonstandard identifier spam on the broken os x pseudo-os. |
|
|
269 | affects IO::AIO and BDB. |
|
|
270 | |
|
|
271 | 3.6 Mon Jan 11 00:43:39 CET 2010 |
|
|
272 | - (libeio) more fixes for the freebsd/apple sendfile - broken by |
|
|
273 | manpage standards, but apparently correct accoridng to actual |
|
|
274 | kernel sources. |
|
|
275 | - add IO::AIO::mmap/munmap support. |
|
|
276 | - add IO::AIO::m(un)lockall support. |
|
|
277 | - clean up manpage. |
|
|
278 | |
|
|
279 | 3.5 Thu Jan 7 21:25:04 CET 2010 |
|
|
280 | - (liebio) fix freebsd sendfile (Vanilla Hsu). |
|
|
281 | - (libeio) also fix darwin sendfile that suffered from a similar bug. |
|
|
282 | - add aio_statvfs as interface to statvfs/fstatvfs. |
|
|
283 | - work around buggy symlink() on cygwin in the testsuite. |
|
|
284 | - wtf. freebsd-8.0 actually passes the testsuite! I knew |
|
|
285 | they could implement fork and semaphores one day! cheers! |
|
|
286 | |
|
|
287 | 3.4 Sat Jan 2 15:13:04 CET 2010 |
|
|
288 | - (libeio) max_poll_time was not properly converted to ticks. |
|
|
289 | - clarify cancel_subs description. |
|
|
290 | - IO::AIO::sendfile did not actually return the return value |
|
|
291 | from the sendfile call. |
|
|
292 | - implement aio_msync, aio_mtouch. |
|
|
293 | - (libeio) tentatively support darwin in sendfile. |
|
|
294 | |
|
|
295 | 3.31 Thu Nov 12 02:14:29 CET 2009 |
|
|
296 | - fix result status documentation of aio_copy, aio_move. |
|
|
297 | - speed up object creation considerably by avoiding |
|
|
298 | hash lookups. |
|
|
299 | |
|
|
300 | 3.3 Wed Aug 5 13:52:58 CEST 2009 |
|
|
301 | - use common::sense. |
|
|
302 | - use common schmorp.h header. |
|
|
303 | - allow integers (file descriptors) in addition to file handles. |
|
|
304 | - take advantage of linux' eventfd (but it seems slower on smp?). |
|
|
305 | - use poll not select on posix platforms. |
|
|
306 | |
|
|
307 | 3.261 Wed Jul 1 10:11:51 CEST 2009 |
|
|
308 | - more 0S X workarounds (patch by Tokuhiro Matsuno). |
|
|
309 | |
|
|
310 | 3.26 Tue Jun 30 09:33:26 CEST 2009 |
|
|
311 | - 0S X of course claims to be posix 2008 but lacks posix_fadvise. |
|
|
312 | try to work around this horribly broken OS in a somewhat hackish |
|
|
313 | way. might help other os's too. |
|
|
314 | |
|
|
315 | 3.25 Sat Jun 27 05:18:26 CEST 2009 |
|
|
316 | - added IO::AIO::fadvise and IO::AIO::sendfile. |
|
|
317 | - (libeio) replaced quicksort+insertion sort by a tuned radix |
|
|
318 | sort + insertion sort, resulting in comparable runtime (usually |
|
|
319 | faster) to the old version, but without any ill side effects on |
|
|
320 | degenerated (for quicksort) data. |
|
|
321 | - (libeio) correctly sort dirs by inodes if we have perfect type |
|
|
322 | knowledge and DIRS_FIRST is used. |
|
|
323 | - (libeio) internally the wrong DT_* constants were used, but no |
|
|
324 | known system has differing EIO_DT_*/DT_* values, so not an issue. |
|
|
325 | - removed a (harmless) assert that was left over on the code |
|
|
326 | but should not have been. |
|
|
327 | - use more correct types (change IO length from IV to VAL64, |
|
|
328 | which makes a difference on systems without 64 bit perls). |
|
|
329 | |
|
|
330 | 3.23 Sat Jun 13 16:57:58 CEST 2009 |
|
|
331 | - fix off-by-one bug in aio_readdir that was introduced in the |
|
|
332 | rushed 3.22 release. |
|
|
333 | |
|
|
334 | 3.22 Sat Jun 13 15:32:40 CEST 2009 |
|
|
335 | - speed up readdirx sort algorithm slightly. |
|
|
336 | - bin/treescan was missing from distro tarball. |
|
|
337 | |
|
|
338 | 3.21 Fri Jun 12 18:45:53 CEST 2009 |
|
|
339 | - new options --dirs and --files for treescan. |
|
|
340 | - install bin/treescan by default. |
|
|
341 | - (libeio) aio_readdir can now be cancelled while executing. |
|
|
342 | - fix a printf format string for 64 bit systems (could lead |
|
|
343 | to problems on big endian 64 bit systems). |
|
|
344 | - do not use qsort() but our own algorithm: glibc initialises |
|
|
345 | the whole locale and I/O subsystem inside qsort, causing |
|
|
346 | a stack overflow on 32 bit machines. The new sort uses much less |
|
|
347 | stack and is more than twice as fast in typical situations. |
|
|
348 | |
|
|
349 | 3.2 Sun Jun 7 20:30:05 CEST 2009 |
|
|
350 | - (libeio) pwrite emulation was even more flawed than intended and did |
|
|
351 | not restore the file offset. |
|
|
352 | - add aio_readdirx, which can return inode and filetype and sort |
|
|
353 | the names in various ways. |
|
|
354 | - unfortunately, utime, chmod, chown on an open file that has just |
|
|
355 | been written can easily block, which caused aio_copy to block the |
|
|
356 | process. no more! |
|
|
357 | - no longer rely on dst path in aio_copy when futime is available. |
|
|
358 | |
|
|
359 | 3.19 Tue Apr 21 22:05:21 CEST 2009 |
|
|
360 | - more perl 5.10 workarounds for aio_read and write. |
|
|
361 | - aio_write no longer modifies the sv (if possible). |
|
|
362 | - aio_read now works correctly with magic values. |
|
|
363 | |
|
|
364 | 3.18 Sun Apr 19 21:17:32 CEST 2009 |
|
|
365 | - better diagnostics when some aio_* functions get passed an illegal fh. |
|
|
366 | - try to avoid crashes due to incompatible 5.10 API changes. grmbl. |
|
|
367 | |
|
|
368 | 3.17 Thu Nov 20 08:45:36 CET 2008 |
|
|
369 | - (libeio) added aio_sync_file_range (untested). |
|
|
370 | - add aio_busy to @IO::AIO::AIO_REQ. |
|
|
371 | |
|
|
372 | 3.16 Wed Oct 22 18:28:01 CEST 2008 |
|
|
373 | - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical |
|
|
374 | part to improve portability to perl 5.8 (reported by szymon). |
|
|
375 | |
|
|
376 | 3.15 Mon Oct 13 00:39:55 CEST 2008 |
|
|
377 | - automatic removal of feeders was broken. |
|
|
378 | - (libeio) use a more robust method to detect whether a feeder |
|
|
379 | has added something to the group or not. |
|
|
380 | |
|
|
381 | 3.1 Thu Oct 2 13:34:40 CEST 2008 |
|
|
382 | - pre-deref the passed callback object, for increased speed |
|
|
383 | and decreased memory usage. |
|
|
384 | - call on_next_submit callback even for aio_group - impact unknown, |
|
|
385 | but seems more correct. |
|
|
386 | - $req->cb now returns the original callback. |
|
|
387 | - (libeio) pass EIO_GROUP/aio_group requests through the queue without |
|
|
388 | requiring a thread switch. |
|
|
389 | - (libeio) status code of aio_futime and aio_utime was always passed 0. |
|
|
390 | - do some other ยต-optimisations. |
|
|
391 | |
|
|
392 | 3.07 Sat Aug 2 16:06:13 CEST 2008 |
|
|
393 | - do not include LIBS in autoconf tests. |
|
|
394 | |
|
|
395 | 3.06 Tue Jul 15 12:41:32 CEST 2008 |
|
|
396 | - move preadwritelock definition before it's first reference, |
|
|
397 | to make it compile again on broken platforms (they still exist) |
|
|
398 | or badly cofngiured perls (redhat...), reported by Rob Bloodgood. |
|
|
399 | |
|
|
400 | 3.05 Thu Jun 19 23:23:52 CEST 2008 |
|
|
401 | - work around perl overriding readdir etc. with thread-unsafe |
|
|
402 | (sic!) versions. |
|
|
403 | |
|
|
404 | 3.04 Wed Jun 18 01:35:38 CEST 2008 |
|
|
405 | - (libeio) fix eio_mknod, which confused it's arguments. |
|
|
406 | - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this |
|
|
407 | is stupid. |
|
|
408 | - (libeio) fix eio__readahead prototype, patch by Jost Krieger. |
|
|
409 | - (libeio) fix a bug that could potentially cause IO::AIO |
|
|
410 | not to get initialised properly. |
|
|
411 | |
|
|
412 | 3.03 Thu May 29 05:33:30 CEST 2008 |
|
|
413 | - (libeio) correctly call pthread_attr_destroy (). |
|
|
414 | - (libeio) work around broken bsd headers once more. |
|
|
415 | - reduce shared library size again by not including wrappers. |
|
|
416 | - max_outstanding could cause poll to enter a busy-waiting loop. |
|
|
417 | - document the new IO::AIO::poll_cb result value. |
|
|
418 | |
|
|
419 | 3.02 Mon May 12 02:32:02 CEST 2008 |
|
|
420 | - fix a memory leak on aio_readlink. |
|
|
421 | - bring back working fchmod. |
|
|
422 | - nop and busy now set result to 0. |
|
|
423 | - set errno to ENOMEM when allocation fails. |
|
|
424 | |
|
|
425 | 3.01 Sun May 11 03:07:03 CEST 2008 |
|
|
426 | - (libeio) make it compile on systems without readahead or readdir_r. |
|
|
427 | - (libeio) improve configure check for readahead availability. |
|
|
428 | - do not try to link against -lrt. |
|
|
429 | - use a separate configure script for IO::AIO (not the libeio one). |
|
|
430 | |
|
|
431 | 3.0 Sun May 11 00:57:14 CEST 2008 |
|
|
432 | - added bin/treescan to the distribution. |
|
|
433 | - switched to using libeio. |
|
|
434 | - LOTS OF INCOMPATIBLE CHANGES: |
|
|
435 | - remove signal functionality, it is not worth the effort. |
|
|
436 | - max_outstanding no longer returns the previous number of requests. |
|
|
437 | - poll_cb no longer returns number of requests. |
|
|
438 | |
|
|
439 | 2.62 Sat Apr 26 13:59:33 CEST 2008 |
|
|
440 | - port to solaris perls configured for old posix |
|
|
441 | (analysed by Jost Krieger). |
|
|
442 | - keep a reference to the perl filehandle object in aio_close, |
|
|
443 | so it doesn't get closed prematurely, leading to ugly races. |
|
|
444 | |
|
|
445 | 2.61 Wed Apr 16 18:45:02 CEST 2008 |
|
|
446 | - fix treescan output duplication and improve output ordering. |
|
|
447 | also display files given on the commandline. |
|
|
448 | - use a different algorithm for aio_close that is faster |
|
|
449 | and probably has even lower chances of blocking. |
|
|
450 | - do our own stack memory management for threads - linux |
|
|
451 | allocates outrageous amounts of VM (not so bad unless you |
|
|
452 | use mlockall...), which severely limits the number of threads |
|
|
453 | on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN |
|
|
454 | and 4096 * sizeof (long) (usually this is 16..64k). |
|
|
455 | |
|
|
456 | 2.6 Sun Mar 30 08:28:11 CEST 2008 |
|
|
457 | - added aio_sync. |
|
|
458 | - added aio_pathsync. |
|
|
459 | - fix prototypes of (void) functions. |
|
|
460 | |
|
|
461 | 2.51 Sat Oct 6 16:04:54 CEST 2007 |
|
|
462 | - perlio isn't generally threadsafe, so aio_close could not work reliably. |
|
|
463 | aio_close now tries a safe hack that might not be that asynchronous |
|
|
464 | (see the manpage for details). |
|
|
465 | - discard callback return values as to not grow the stack endlessly |
|
|
466 | when poll_cb handles many requests without returning. |
|
|
467 | - minor code cleanups. |
|
|
468 | |
|
|
469 | 2.5 Thu Oct 4 14:49:08 CEST 2007 |
|
|
470 | - replaced _fd2fh with faster xs code. |
|
|
471 | - aio_close will now try to do "the right thing" and thus might |
|
|
472 | work sensibly for the very first time. |
|
|
473 | |
|
|
474 | 2.41 Mon Sep 24 21:28:21 CEST 2007 |
|
|
475 | - after fork, invest some work to make sure that the poll_fileno |
|
|
476 | stays stable (by dup2'ing the new fd over the old one), to make |
|
|
477 | it easier for programs/libs that don't control their forking |
|
|
478 | behaviour and cannot recreate their watchers. |
|
|
479 | |
|
|
480 | 2.4 Sun Aug 5 18:44:22 CEST 2007 |
|
|
481 | - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux |
|
|
482 | successfully demonstrated that you can block on futimes...). |
|
|
483 | - allow undef as fileoffset for aio_read/write and use read/write(2) |
|
|
484 | internally (useful for sockets or O_APPEND handles). |
|
|
485 | - allow undef for length in aio_write. |
|
|
486 | - negative dataoffsets work as expected now in aio_read/aio_write. |
|
|
487 | - use NV instead of UV for 32 bit perls and file offsets, as NVs |
|
|
488 | have a larger range then. |
|
|
489 | - shared code between BDB and IO::AIO. |
|
|
490 | - aio_busy was completely broken. now fixed. |
|
|
491 | - readahead emulation now returns something. |
|
|
492 | - correctly set errno to ENOSYS on unimplemented functions |
|
|
493 | (should never happen, though). |
|
|
494 | - large changes to make it partially compile and run on win32, |
|
|
495 | but win32 lacks too much functionality, and perl overrides way |
|
|
496 | too many functions with crashing versions. |
|
|
497 | |
|
|
498 | 2.33 Tue Jan 23 23:55:41 CET 2007 |
|
|
499 | - fix install path (Andreas J. Koenig). |
|
|
500 | |
|
|
501 | 2.32 Mon Jan 22 16:56:23 CET 2007 |
|
|
502 | - added aio_rmtree. |
|
|
503 | - wow, aio_mkdir was missing. |
|
|
504 | - aio_load did return undef on error, not -1. |
|
|
505 | - use prefixexp not prefix in autoconf.pm |
|
|
506 | (suggested by ... rt.cpan.org unreachable). |
|
|
507 | - avoid installing autoconf.pm. |
|
|
508 | |
|
|
509 | 2.31 Sat Jan 6 03:46:02 CET 2007 |
|
|
510 | - added aio_load. |
|
|
511 | |
|
|
512 | 2.3 Sat Dec 23 05:48:07 CET 2006 |
|
|
513 | - fix off-by-one bug in aio_read, causing memory corruption |
|
|
514 | or crashes. |
|
|
515 | |
|
|
516 | 2.21 Fri Dec 22 05:03:38 CET 2006 |
|
|
517 | - minor doc updates. |
|
|
518 | - minor cleanups. |
|
|
519 | - IO::AIO::poll returns request count. |
|
|
520 | - undocumented and unfinished async-signal-reporting. |
|
|
521 | |
|
|
522 | 2.2 Tue Oct 31 00:31:00 CET 2006 |
|
|
523 | - minor doc updates. |
|
|
524 | - added aio_readlink. |
|
|
525 | - properly zero-terminate aio_read buffer. |
|
|
526 | - fix aio_read/write with nonzero dataoffset. |
|
|
527 | - reduced size of aio request structure. |
|
|
528 | - better diagnostics when pathnames etc. are not byte-encoded; |
|
|
529 | do not leak request in that case, either. |
|
|
530 | |
|
|
531 | 2.1 Sun Oct 29 02:01:57 CET 2006 |
|
|
532 | - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by |
|
|
533 | IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. |
|
|
534 | - fix a bug in aio_move where it would fail everytime |
|
|
535 | it would have to copy files manually. |
|
|
536 | - doc updates. |
|
|
537 | - start threads only on (very low) demand. |
|
|
538 | - end superfluous threads automatically after 10s idling. |
|
|
539 | - add IO::AIO::max_idle to control this. |
|
|
540 | - some tuning applied to random places. |
|
|
541 | - add aio_mknod. |
|
|
542 | |
|
|
543 | 2.0 Thu Oct 26 18:27:58 CEST 2006 |
|
|
544 | - minor incompatibility: max_outstanding semantics have changed. |
|
|
545 | - major rewrite, consider all functionality EXPERIMENTAL. |
|
|
546 | - aio requests can be cancelled. |
|
|
547 | - callbacks can be (re-)set later. |
|
|
548 | - aio requests can choose between 9 priorities. |
|
|
549 | - add aio_group: aio requests can be grouped |
|
|
550 | into composite requests. |
|
|
551 | - generator interface for groups. |
|
|
552 | - add IO::AIO::poll_some. |
|
|
553 | - major documentation improvements. |
|
|
554 | - very minor bugfixes. |
|
|
555 | - add aio_nop for dummy requests. |
|
|
556 | - add aio_busy mainly for benchmarking and debugging. |
|
|
557 | - use "fast" mutexes on linux. |
|
|
558 | - use dynamic (and larger) buffers instead of |
|
|
559 | putting them onto the stack. |
|
|
560 | - optimise x86 and amd64 a bit. |
|
|
561 | - better error checking when ENOMEM. |
|
|
562 | - hopefully fix mem and dirp leaks on fork. |
|
|
563 | - warn about broken perl malloc. |
|
|
564 | - compiles on cygwin (but pread is broken on cygwin |
|
|
565 | which is not detected by autoconf, so you have to |
|
|
566 | edit autoconf/config.h yourself to enable emulation). |
|
|
567 | |
|
|
568 | 1.8 Sat Jun 24 22:20:44 CEST 2006 |
|
|
569 | - add and/or document aio_rename, aio_link, aio_symlink and aio_move. |
|
|
570 | |
|
|
571 | 1.73 Wed Mar 1 22:49:32 CET 2006 |
|
|
572 | - codename "jost" |
|
|
573 | - AIX/Solaris(?) aren't being helpful again, hardcode a value |
|
|
574 | for NAME_MAX and drive with your eyes closed (reported by |
|
|
575 | wcooley@nakedape.cc). |
|
|
576 | |
|
|
577 | 1.72 Thu Feb 2 00:40:44 CET 2006 |
|
|
578 | - another minor bug in aio_scandir, again, the callback was called |
|
|
579 | twice when the directory can't be stat'ed. |
|
|
580 | |
|
|
581 | 1.71 Mon Dec 26 20:20:03 CET 2005 |
|
|
582 | - grr, another minor bug in aio_scandir, this time resulting |
|
|
583 | in a runtime error. |
|
|
584 | |
|
|
585 | 1.7 Mon Dec 26 19:29:48 CET 2005 |
|
|
586 | - aio_scandir errornously called callback twice in some cases. |
|
|
587 | - added AnyEvent example. |
|
|
588 | |
|
|
589 | 1.61 Wed Sep 7 19:40:42 CEST 2005 |
|
|
590 | - no longer include $Config{libs}, as distros include too much |
|
|
591 | garbage in there that is not installed on typical systems |
|
|
592 | (for example, debian links perl against -lgdbm and many more |
|
|
593 | libraries despite perl not needing it, slowing down startup and |
|
|
594 | wasting memory). |
| 2 | |
595 | |
| 3 | 1.6 Tue Aug 30 17:44:44 CEST 2005 |
596 | 1.6 Tue Aug 30 17:44:44 CEST 2005 |
| 4 | - added aio_readdir, aio_scandir. |
597 | - added aio_readdir, aio_scandir. |
| 5 | - added aio_sendfile, including sendfile emulation when sendfile |
598 | - added aio_sendfile, including sendfile emulation when sendfile |
| 6 | isn't available. Linux, FreeBSD and HP-UX might work (sendfilev |
599 | isn't available. Linux, FreeBSD and HP-UX might work (sendfilev |

| 13 | be C89 compatible, but no guarantees for future ones. |
