50
51 - disable syscalls on solaris, as perl seems to provide an
52 incompatible syscall prototype that clashes with sys/syscall.h.
53
544.75 Wed Dec 30 08:44:55 CET 2020
55 - removed leftover debug output from treescan.
56 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
57 FSCONFIG_*, MOUNT_ATTR_* constants.
58
594.74 Tue Dec 29 16:19:28 CET 2020
60 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
61 - rework bin/treescan to avoid recursion. This fixes two bugs
62 where a deep directory traversal or a lot of command line
63 arguments could cause it to crash.
64 - added (but not documented) open_tree, AT_* and move_mount flags.
65 - support defining syscall numbers in gendef0.
66
674.73 Fri Dec 4 02:08:37 CET 2020
68 - def0.h was not uptodate, running into musl problems
69 (reported by B Fraser).
70 - IO::AIO::splice and IO::AIO::tee didn't properly return
71 64 bit values.
72 - added IO::AIO::accept4.
73 - add various F_SEAL related fcntl constants.
74 - removed experimental marker for fdlimit functions.
75 - fiemap now includes the last segment even if it overflows
76 the end offset, which is arguably the correct behaviour.
77
784.72 Wed Apr 3 04:56:03 CEST 2019
79 - (libeio) if fd 0 is available do not use it for aio_wd, as it
80 collides with IO::AIO::CWD.
81 - added IO::AIO::memfd_create.
82 - correctly include <sys/uio.h> in the vmsplice test.
83 - reduce codesize by ~7% on amd64 by declaring more functions
84 as noinline.
85 - documentation fixes and updates.
86 - experimental and undocumented preliminary support for synchronous statx.
87
884.71 Sun Mar 10 13:09:26 CET 2019
89 - due to an error in the linux manpages, the configure tests
90 for readahead, sync_file_range, splice etc. failed. This has been fixed.
91
924.7 Mon Mar 4 11:28:13 CET 2019
93 - majorly speed up scandir for the very special case of a non-POSIX
94 filesystem that nevertheless reports valid dt_type information.
95 The only known filesystem of this type is currently btrfs, which
96 didn't get it's act together to implement POSIX semantics in all
97 these years, and I am tired of waiting.
98 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
99 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
100 were detected by autoconf.
101
1024.6 Sat Aug 25 21:58:36 CEST 2018
103 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
104 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
105 but only st_gen on openbsd because they compiled their perl without support
106 for birthtimes).
107 - fix madvise and munlock to properly support negative offsets.
108 - allocate fd for the aio_close at boot time, to guarantee it working
109 later, rather than calling abort when it fails. also avoids
110 close-on-exec race issues after module load.
111 - #undef utime on win32, maybe this helps some reports of utime hangs.
112 - minor doc improvements.
113 - minor configure cleanups.
114 - use $Config{perllibs} instead of libs for configure. might help people
115 who didn't install all perl dependencies (might break things as well).
116
1174.54 Tue Aug 14 13:54:48 CEST 2018
118 - include sys/mkdev.h or sys/sysmacros.h if available.
119 - further tweaks to configure invocation for systems requiring --rpath.
120 - no longer rely on custom paths on win32 platforms.
121 - try to work around buggy PAGESIZE macro on solaris.
122
1234.53 Tue Aug 14 11:27:50 CEST 2018
124 - add $Config{libs} to LIBS for configure, to work around systems
125 with broken library dependencies (... openbsd).
126
1274.52 Sun Aug 12 08:09:45 CEST 2018
128 - config.h.in was missing in distribution.
129
1304.51 Sun Aug 12 07:24:14 CEST 2018
131 - complete rework of the autoconf framework: IO::AIO now uses its own
132 config.h, separate from libeio, and tries to test the actual perl
133 environment, not the standard system environment.
134 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
135 stat functions.
136 - removed non-portable C++ syntax from eio.c.
137 - try to fix readdir tests on cygwin spuriously failing.
138
1394.5 Wed Aug 1 00:23:55 CEST 2018
140 - aio_mtouch touch all pages as requested, not just the first page in most cases.
141 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
142 and MREMAP_FIXED.
143 - add O_ACCMODE.
144 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
145
1464.4 Tue Feb 20 07:54:12 CET 2018
147 - new aio_slurp request.
148 - add (experimental) IO::AIO::eventfd and timerfd* function.
149 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
150 - point out that aio_copy overwrites existing files.
151 - removed filesystem magic number table from aio_statvfs docs as
152 statvfs doesn't actually return this info at all (statfs does).
153 - add a bunch of (mostly linux-specific) constants for use in ioctls
154 (see aio_ioctl docs).
155 - treescan now has a proper manpage and useful --help output.
156 - new option --sync in treescan, to sync everything in a subtree.
157 - changed default for aio_msync flags to MSYNC_SYNC.
158 - document offset/length behaviour of mprotect/madvise.
159 - support linux's renameat2 (via aio_rename2).
160 - add aio_rename2, an aio_rename with flags.
161 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
162 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
163 - (libeio) use posix_close if available.
164 - (libeio) internal close() calls no longer disturb errno.
165 - add IO:AIO::FALLOC_FL_UNSHARE.
166 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
167 and better eventfd detection.
168
1694.34 Sun May 1 19:18:24 CEST 2016
170 - def0.h was not properly generated during previous release, causing
171 compile errors on various platforms.
172 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
173 - removed duplicate definition of MAP_HUGETLB, that was found due to
174 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
175 - added (untested!) aio_fcntl, aio_ioctl requests.
176 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
177 as manpages-dev originally claimed.
178
1794.33 Mon Jan 18 12:50:10 CET 2016
180 - add IO::AIO::pipe2 function.
181 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
182 constants.
183 - added support for O_TMPFILE and O_PATH constants.
184 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
185 consdtants, whether they can be sensibly used or not.
186 - use NO_INIT where applicable.
187 - update libecb.
188 - added stability canary support.
189 - updated linux super magic table to 4.3.3.
190
1914.32 Wed Feb 11 20:32:11 CET 2015
192 - replace off_t by STRLEN where appropriate, should not result in
193 user-visible changes.
194 - update ecb.h for C11 compatibility.
195
1964.31 Tue Jun 3 03:29:27 CEST 2014
197 - work around more 5.20 bugs. backwards compatibility my ass.
198
1994.3 Fri Apr 11 06:22:38 CEST 2014
200 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
201 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
202 in 5.18. What's so attractive about giving a shit about backwards
203 compatibility - I will never understand.
204
2054.2 Sat Jan 25 01:13:14 CET 2014
206 - aio_group could corrupt memory because it didn't restore
207 the stack after req_submit.
208 - be more careful on (e.g. permission) errors in bin/treescan.
209 - work around changes in ExtUtils::MakeMaker.
210 - (libeio) implement aio_realpath for win32.
211 - (xthread) work around compile time bugs in ptw32.
212 - added IO::AIO::pipesize.
213 - (libecb) insignificant update.
214
2154.19 Sun Jan 6 12:47:26 CET 2013
216 - avoid endless loop in fiemap with some XFS files.
217 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
218 and call rename/rmdir instead of renameat/unlinkat.
219
2204.18 Thu Oct 11 07:01:26 CEST 2012
221 - fix unintended xthread_create by intentionalising it :)
222
2234.17 Thu Oct 11 05:19:47 CEST 2012
224 - rename aio_fallocate to aio_allocate, to match documentation.
225 - add list of linux fsid values to aio_statvfs docs.
226 - work around a bug in btrfs' FIEMAP ioctl implementation.
227 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
228 as per unix spec.
229
2304.16 Tue Aug 14 05:39:03 CEST 2012
231 - aio_statvfs was wromgly marked for wd emulation, causing
232 it to malfunction for paths.
233 - fix a crash in aio_fiemap, when used on ranges without any
234 extents.
235 - work around linux kernel bug (at least in 3.2): kernel might
236 trash fiemap input arguments.
237 - work around linux kernel bug (at least in 3.2): kernel does not
238 set FIEMAP_EXTENT_LAST on last segment.
239 - work around linux kernel bug (at least in 3.2): kernel silently
240 truncates segment count if a file.
241 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
242 to quick overview.
243 - splice can corrupt data.
244 - (libeio) remove pread/pwrite emulation.
245 - do not grow mmaped scalars in aio_read.
246 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
247 - provide pread/pwrite for win32, making it link again on native win32.
248
2494.15 Tue Apr 10 06:59:00 CEST 2012
250 - always include linux/types.h for fiemap, for compatibility to
251 ancient systems (Paul Howarth).
252 - experimental support for IO::AIO::splice and ::tee (no aio_...).
253 - provide SEEK_HOLE and SEEK_DATA, if available.
254 - work around (again!) an immensely stupid bug in RHEL, defining
255 autoconf macros in linux system headers (analysed by Paul Howarth).
256
2574.14 Sat Apr 7 02:45:18 CEST 2012
258 - fix stat structure usage on windows, which caused bogus stat results.
259 - (libeio) make readahead emulation behave more like actual readahead by never failing.
260 - new request aio_seek.
261 - new request aio_fiemap.
262 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
263
2644.12 Fri Dec 30 08:51:25 CET 2011
265 - realpath would return a random value if the name was too long,
266 instead of -1.
267 - port to c89.
268
2694.11 Mon Oct 10 00:24:11 CEST 2011
270 - libeio didn't compile on !linux (Paul Howarth).
271
2724.1 Sun Oct 9 10:24:11 CEST 2011
273 - IO::AIO did access uninitialised memory on unsuccessful stats.
274 - (libeio) added syncfs syscall wrapper.
275 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
276 - (libeio) support multiple indepenent working directories.
277 - applied speling corrections by Nicholas Bamber.
278 - tune treescan #threads and #outstanding requests a bit.
279 - reduce the number of file descriptors in use at any one time
280 in treescan, to avoid running out of them (and using too much ram).
281 - take advantage of working directoriy abstractions
282 in aio_scandir and treescan.
283 - reduce compiled size by ~10% by not inlining some key functionality.
284 - added --progress switch to treescan.
285
2864.0 Mon Jul 18 05:01:10 CEST 2011
287 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
288 see FORK BEHAVIOUR in manpage for details.
289 - passes testsuite on win32 now and may actually work
290 (activestate 5.10.1 / MSVC6, YMMV).
291 - (libeio) fix a deadlock where a wakeup signal could be missed when
292 a timeout occured at the same time.
293 - (libeio) added realpath.
294 - (libeio) added fallocate.
295 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
296 - (libeio) do not acquire any locks when forking.

298
2993.93 Wed Jun 29 23:44:18 CEST 2011
300 - ECB.H WAS MISSING.
301
3023.92 Wed Jun 29 14:45:41 CEST 2011
303 - ecb.h was missing.
304
3053.91 Wed Jun 29 13:24:42 CEST 2011
306 - (libeio) work around a Linux (and likely FreeBSD and other
307 kernels) bug where sendfile would not transfer all the requested
308 bytes on large transfers, using a heuristic.
309 - buggy sendfile caused aio_move/copy to sometimes fail for big
310 files (fortunately it checks that the whole file has been
311 transferred...)
312 - use libecb for higher performance and higher portability.
313 - (libeio) disable sendfile on darwin, it's too broken.
314 - disable fork tests on !linux, as only linux supports mixing
315 pthread and fork in perl.
316 - document the fact that fork doesn't work anymore when using
317 this module, on anything !GNU/Linux.
318 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
319 run on a 0.1MHz cpu. Or so.
320
3213.9 Fri May 27 02:43:47 CEST 2011
322 - (libeio) fix memory corruption in aio_readdirx for the flags
323 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
324 - add lots of newer POSIX and GNU/Linux-specific open
325 flags.
326
3273.8 Sun Mar 27 12:25:33 CEST 2011
328 - use nonstandard but maybe-working-on-bsd fork technique.
329 - support a max_idle value of 0.
330 - support setting of idle timeout value (IO::AIO::idle_timeout).
331
3323.72 Fri Feb 11 04:25:38 CET 2011
333 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
334 - aio_mknod always used a dev_t value of 0.
335 - new treescan option: --grep.
336 - add more S_IF macros, and major/minor/makedev "macros".
337
3383.71 Thu Dec 30 08:18:46 CET 2010
339 - the numerical result value passed to callbacks did not stringify
340 correctly, due to internal reuse and failure to reset the sv flags.
341 - actually test for posix_[mf]advise, as at least uClibc defines
342 _POSIX_ADVISORY_INFO without actually having any of the required
343 funcitonality. ugh.
344
3453.7 Mon Nov 1 23:00:34 CET 2010
346 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
347 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
348 - document the sad state of affairs w.r.t. pthread on many bsds.
349 - do not enable mmap on systems without _POSIX_MAPPED_FILES
350 (openbsd 4.8).
351 - do not leak memory in IO::AIO::mmap when the scalar already
352 had string-data.
353 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
354 them.
355 - cache the result IV, for a minor speedup in the common case.
356 - croak when an mmapped-scalar changes location, to detect
357 user-errors better.
358 - fix aio_readlink prototype.
359
3603.65 Wed Mar 31 02:45:05 CEST 2010
361 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
362 cut off long pathnames in aio_readlink (based on patch by
363 Rasmus Andersson).
364 - a double fork partially killed the event pipe (great testcase
365 by dormando). affects IO::AIO, BDB and Async::Interrupt.
366 - suck steve's dick and rename our symbols to avoid colliding
367 with nonstandard identifier spam on the broken os x pseudo-os.
368 affects IO::AIO and BDB.
369
3703.6 Mon Jan 11 00:43:39 CET 2010
371 - (libeio) more fixes for the freebsd/apple sendfile - broken by
372 manpage standards, but apparently correct accoridng to actual
373 kernel sources.
374 - add IO::AIO::mmap/munmap support.
375 - add IO::AIO::m(un)lockall support.
376 - clean up manpage.
377
3783.5 Thu Jan 7 21:25:04 CET 2010
379 - (liebio) fix freebsd sendfile (Vanilla Hsu).
380 - (libeio) also fix darwin sendfile that suffered from a similar bug.
381 - add aio_statvfs as interface to statvfs/fstatvfs.
382 - work around buggy symlink() on cygwin in the testsuite.
383 - wtf. freebsd-8.0 actually passes the testsuite! I knew
384 they could implement fork and semaphores one day! cheers!
385
3863.4 Sat Jan 2 15:13:04 CET 2010
387 - (libeio) max_poll_time was not properly converted to ticks.
388 - clarify cancel_subs description.
389 - IO::AIO::sendfile did not actually return the return value
390 from the sendfile call.
391 - implement aio_msync, aio_mtouch.
392 - (libeio) tentatively support darwin in sendfile.
393
3943.31 Thu Nov 12 02:14:29 CET 2009
395 - fix result status documentation of aio_copy, aio_move.
396 - speed up object creation considerably by avoiding
397 hash lookups.
398
3993.3 Wed Aug 5 13:52:58 CEST 2009
400 - use common::sense.
401 - use common schmorp.h header.
402 - allow integers (file descriptors) in addition to file handles.
403 - take advantage of linux' eventfd (but it seems slower on smp?).
404 - use poll not select on posix platforms.
405
4063.261 Wed Jul 1 10:11:51 CEST 2009
407 - more 0S X workarounds (patch by Tokuhiro Matsuno).
408
4093.26 Tue Jun 30 09:33:26 CEST 2009
410 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
411 try to work around this horribly broken OS in a somewhat hackish
412 way. might help other os's too.
413
4143.25 Sat Jun 27 05:18:26 CEST 2009
415 - added IO::AIO::fadvise and IO::AIO::sendfile.
416 - (libeio) replaced quicksort+insertion sort by a tuned radix
417 sort + insertion sort, resulting in comparable runtime (usually
418 faster) to the old version, but without any ill side effects on
419 degenerated (for quicksort) data.
420 - (libeio) correctly sort dirs by inodes if we have perfect type
421 knowledge and DIRS_FIRST is used.
422 - (libeio) internally the wrong DT_* constants were used, but no
423 known system has differing EIO_DT_*/DT_* values, so not an issue.
424 - removed a (harmless) assert that was left over on the code
425 but should not have been.
426 - use more correct types (change IO length from IV to VAL64,
427 which makes a difference on systems without 64 bit perls).
428
4293.23 Sat Jun 13 16:57:58 CEST 2009
430 - fix off-by-one bug in aio_readdir that was introduced in the
431 rushed 3.22 release.
432
4333.22 Sat Jun 13 15:32:40 CEST 2009
434 - speed up readdirx sort algorithm slightly.
435 - bin/treescan was missing from distro tarball.
436
4373.21 Fri Jun 12 18:45:53 CEST 2009
438 - new options --dirs and --files for treescan.
439 - install bin/treescan by default.
440 - (libeio) aio_readdir can now be cancelled while executing.
441 - fix a printf format string for 64 bit systems (could lead
442 to problems on big endian 64 bit systems).
443 - do not use qsort() but our own algorithm: glibc initialises
444 the whole locale and I/O subsystem inside qsort, causing
445 a stack overflow on 32 bit machines. The new sort uses much less
446 stack and is more than twice as fast in typical situations.
447
4483.2 Sun Jun 7 20:30:05 CEST 2009
449 - (libeio) pwrite emulation was even more flawed than intended and did
450 not restore the file offset.
451 - add aio_readdirx, which can return inode and filetype and sort
452 the names in various ways.
453 - unfortunately, utime, chmod, chown on an open file that has just
454 been written can easily block, which caused aio_copy to block the
455 process. no more!
456 - no longer rely on dst path in aio_copy when futime is available.
457
4583.19 Tue Apr 21 22:05:21 CEST 2009
459 - more perl 5.10 workarounds for aio_read and write.
460 - aio_write no longer modifies the sv (if possible).
461 - aio_read now works correctly with magic values.
462
4633.18 Sun Apr 19 21:17:32 CEST 2009
464 - better diagnostics when some aio_* functions get passed an illegal fh.
465 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
466
4673.17 Thu Nov 20 08:45:36 CET 2008
468 - (libeio) added aio_sync_file_range (untested).
469 - add aio_busy to @IO::AIO::AIO_REQ.
470
4713.16 Wed Oct 22 18:28:01 CEST 2008
472 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
473 part to improve portability to perl 5.8 (reported by szymon).
474
4753.15 Mon Oct 13 00:39:55 CEST 2008
476 - automatic removal of feeders was broken.
477 - (libeio) use a more robust method to detect whether a feeder
478 has added something to the group or not.
479
4803.1 Thu Oct 2 13:34:40 CEST 2008
481 - pre-deref the passed callback object, for increased speed
482 and decreased memory usage.
483 - call on_next_submit callback even for aio_group - impact unknown,
484 but seems more correct.
485 - $req->cb now returns the original callback.
486 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
487 requiring a thread switch.
488 - (libeio) status code of aio_futime and aio_utime was always passed 0.
489 - do some other ยต-optimisations.
490
4913.07 Sat Aug 2 16:06:13 CEST 2008
492 - do not include LIBS in autoconf tests.
493
4943.06 Tue Jul 15 12:41:32 CEST 2008
495 - move preadwritelock definition before it's first reference,
496 to make it compile again on broken platforms (they still exist)
497 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
498
4993.05 Thu Jun 19 23:23:52 CEST 2008
500 - work around perl overriding readdir etc. with thread-unsafe
501 (sic!) versions.
502
5033.04 Wed Jun 18 01:35:38 CEST 2008
504 - (libeio) fix eio_mknod, which confused it's arguments.
505 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
506 is stupid.
507 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
508 - (libeio) fix a bug that could potentially cause IO::AIO
509 not to get initialised properly.
510
5113.03 Thu May 29 05:33:30 CEST 2008
512 - (libeio) correctly call pthread_attr_destroy ().
513 - (libeio) work around broken bsd headers once more.
514 - reduce shared library size again by not including wrappers.
515 - max_outstanding could cause poll to enter a busy-waiting loop.
516 - document the new IO::AIO::poll_cb result value.
517
5183.02 Mon May 12 02:32:02 CEST 2008
519 - fix a memory leak on aio_readlink.
520 - bring back working fchmod.
521 - nop and busy now set result to 0.
522 - set errno to ENOMEM when allocation fails.
523
5243.01 Sun May 11 03:07:03 CEST 2008
525 - (libeio) make it compile on systems without readahead or readdir_r.
526 - (libeio) improve configure check for readahead availability.
527 - do not try to link against -lrt.
528 - use a separate configure script for IO::AIO (not the libeio one).
529
5303.0 Sun May 11 00:57:14 CEST 2008
531 - added bin/treescan to the distribution.
532 - switched to using libeio.
533 - LOTS OF INCOMPATIBLE CHANGES:
534 - remove signal functionality, it is not worth the effort.
535 - max_outstanding no longer returns the previous number of requests.
536 - poll_cb no longer returns number of requests.
537
5382.62 Sat Apr 26 13:59:33 CEST 2008
539 - port to solaris perls configured for old posix
540 (analysed by Jost Krieger).
541 - keep a reference to the perl filehandle object in aio_close,
542 so it doesn't get closed prematurely, leading to ugly races.
543
5442.61 Wed Apr 16 18:45:02 CEST 2008
545 - fix treescan output duplication and improve output ordering.
546 also display files given on the commandline.
547 - use a different algorithm for aio_close that is faster
548 and probably has even lower chances of blocking.
549 - do our own stack memory management for threads - linux
550 allocates outrageous amounts of VM (not so bad unless you
551 use mlockall...), which severely limits the number of threads
552 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
553 and 4096 * sizeof (long) (usually this is 16..64k).
554
5552.6 Sun Mar 30 08:28:11 CEST 2008
10 - added aio_sync. 556 - added aio_sync.
11 - added aio_pathsync. 557 - added aio_pathsync.
558 - fix prototypes of (void) functions.
12 559
132.51 Sat Oct 6 16:04:54 CEST 2007 5602.51 Sat Oct 6 16:04:54 CEST 2007
14 - perlio isn't generally threadsafe, so aio_close could not work reliably. 561 - perlio isn't generally threadsafe, so aio_close could not work reliably.
15 aio_close now tries a safe hack that might not be that asynchronous 562 aio_close now tries a safe hack that might not be that asynchronous
16 (see the manpage for details). 563 (see the manpage for details).
