50
51 - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants.
52
534.76 Tue Jul 27 20:45:01 CEST 2021
54 - add autoconf test for siginfo_t, which is, of course, not
55 available on windows (reported by Peter Petky).
56 - disable syscalls on solaris, as perl seems to provide an
57 incompatible syscall prototype that clashes with sys/syscall.h.
58 - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
59 MAP_UNINITIALIZED.
60
614.75 Wed Dec 30 08:44:55 CET 2020
62 - removed leftover debug output from treescan.
63 - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
64 FSCONFIG_*, MOUNT_ATTR_* constants.
65
664.74 Tue Dec 29 16:19:28 CET 2020
67 - added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
68 - rework bin/treescan to avoid recursion. This fixes two bugs
69 where a deep directory traversal or a lot of command line
70 arguments could cause it to crash.
71 - added (but not documented) open_tree, AT_* and move_mount flags.
72 - support defining syscall numbers in gendef0.
73
744.73 Fri Dec 4 02:08:37 CET 2020
75 - def0.h was not uptodate, running into musl problems
76 (reported by B Fraser).
77 - IO::AIO::splice and IO::AIO::tee didn't properly return
78 64 bit values.
79 - added IO::AIO::accept4.
80 - add various F_SEAL related fcntl constants.
81 - removed experimental marker for fdlimit functions.
82 - fiemap now includes the last segment even if it overflows
83 the end offset, which is arguably the correct behaviour.
84
854.72 Wed Apr 3 04:56:03 CEST 2019
86 - (libeio) if fd 0 is available do not use it for aio_wd, as it
87 collides with IO::AIO::CWD.
88 - added IO::AIO::memfd_create.
89 - correctly include <sys/uio.h> in the vmsplice test.
90 - reduce codesize by ~7% on amd64 by declaring more functions
91 as noinline.
92 - documentation fixes and updates.
93 - experimental and undocumented preliminary support for synchronous statx.
94
954.71 Sun Mar 10 13:09:26 CET 2019
96 - due to an error in the linux manpages, the configure tests
97 for readahead, sync_file_range, splice etc. failed. This has been fixed.
98
994.7 Mon Mar 4 11:28:13 CET 2019
100 - majorly speed up scandir for the very special case of a non-POSIX
101 filesystem that nevertheless reports valid dt_type information.
102 The only known filesystem of this type is currently btrfs, which
103 didn't get it's act together to implement POSIX semantics in all
104 these years, and I am tired of waiting.
105 - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
106 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
107 were detected by autoconf.
108
1094.6 Sat Aug 25 21:58:36 CEST 2018
110 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
111 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
112 but only st_gen on openbsd because they compiled their perl without support
113 for birthtimes).
114 - fix madvise and munlock to properly support negative offsets.
115 - allocate fd for the aio_close at boot time, to guarantee it working
116 later, rather than calling abort when it fails. also avoids
117 close-on-exec race issues after module load.
118 - #undef utime on win32, maybe this helps some reports of utime hangs.
119 - minor doc improvements.
120 - minor configure cleanups.
121 - use $Config{perllibs} instead of libs for configure. might help people
122 who didn't install all perl dependencies (might break things as well).
123
1244.54 Tue Aug 14 13:54:48 CEST 2018
125 - include sys/mkdev.h or sys/sysmacros.h if available.
126 - further tweaks to configure invocation for systems requiring --rpath.
127 - no longer rely on custom paths on win32 platforms.
128 - try to work around buggy PAGESIZE macro on solaris.
129
1304.53 Tue Aug 14 11:27:50 CEST 2018
131 - add $Config{libs} to LIBS for configure, to work around systems
132 with broken library dependencies (... openbsd).
133
1344.52 Sun Aug 12 08:09:45 CEST 2018
135 - config.h.in was missing in distribution.
136
1374.51 Sun Aug 12 07:24:14 CEST 2018
138 - complete rework of the autoconf framework: IO::AIO now uses its own
139 config.h, separate from libeio, and tries to test the actual perl
140 environment, not the standard system environment.
141 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
142 stat functions.
143 - removed non-portable C++ syntax from eio.c.
144 - try to fix readdir tests on cygwin spuriously failing.
145
1464.5 Wed Aug 1 00:23:55 CEST 2018
147 - aio_mtouch touch all pages as requested, not just the first page in most cases.
148 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
149 and MREMAP_FIXED.
150 - add O_ACCMODE.
151 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
152
1534.4 Tue Feb 20 07:54:12 CET 2018
154 - new aio_slurp request.
155 - add (experimental) IO::AIO::eventfd and timerfd* function.
156 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
157 - point out that aio_copy overwrites existing files.
158 - removed filesystem magic number table from aio_statvfs docs as
159 statvfs doesn't actually return this info at all (statfs does).
160 - add a bunch of (mostly linux-specific) constants for use in ioctls
161 (see aio_ioctl docs).
162 - treescan now has a proper manpage and useful --help output.
163 - new option --sync in treescan, to sync everything in a subtree.
164 - changed default for aio_msync flags to MSYNC_SYNC.
165 - document offset/length behaviour of mprotect/madvise.
166 - support linux's renameat2 (via aio_rename2).
167 - add aio_rename2, an aio_rename with flags.
168 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
169 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
170 - (libeio) use posix_close if available.
171 - (libeio) internal close() calls no longer disturb errno.
172 - add IO:AIO::FALLOC_FL_UNSHARE.
173 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
174 and better eventfd detection.
175
1764.34 Sun May 1 19:18:24 CEST 2016
177 - def0.h was not properly generated during previous release, causing
178 compile errors on various platforms.
179 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
180 - removed duplicate definition of MAP_HUGETLB, that was found due to
181 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
182 - added (untested!) aio_fcntl, aio_ioctl requests.
183 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
184 as manpages-dev originally claimed.
185
1864.33 Mon Jan 18 12:50:10 CET 2016
187 - add IO::AIO::pipe2 function.
188 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
189 constants.
190 - added support for O_TMPFILE and O_PATH constants.
191 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
192 consdtants, whether they can be sensibly used or not.
193 - use NO_INIT where applicable.
194 - update libecb.
195 - added stability canary support.
196 - updated linux super magic table to 4.3.3.
197
1984.32 Wed Feb 11 20:32:11 CET 2015
199 - replace off_t by STRLEN where appropriate, should not result in
200 user-visible changes.
201 - update ecb.h for C11 compatibility.
202
2034.31 Tue Jun 3 03:29:27 CEST 2014
204 - work around more 5.20 bugs. backwards compatibility my ass.
205
2064.3 Fri Apr 11 06:22:38 CEST 2014
207 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
208 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
209 in 5.18. What's so attractive about giving a shit about backwards
210 compatibility - I will never understand.
211
2124.2 Sat Jan 25 01:13:14 CET 2014
213 - aio_group could corrupt memory because it didn't restore
214 the stack after req_submit.
215 - be more careful on (e.g. permission) errors in bin/treescan.
216 - work around changes in ExtUtils::MakeMaker.
217 - (libeio) implement aio_realpath for win32.
218 - (xthread) work around compile time bugs in ptw32.
219 - added IO::AIO::pipesize.
220 - (libecb) insignificant update.
221
2224.19 Sun Jan 6 12:47:26 CET 2013
223 - avoid endless loop in fiemap with some XFS files.
224 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
225 and call rename/rmdir instead of renameat/unlinkat.
226
2274.18 Thu Oct 11 07:01:26 CEST 2012
228 - fix unintended xthread_create by intentionalising it :)
229
2304.17 Thu Oct 11 05:19:47 CEST 2012
231 - rename aio_fallocate to aio_allocate, to match documentation.
232 - add list of linux fsid values to aio_statvfs docs.
233 - work around a bug in btrfs' FIEMAP ioctl implementation.
234 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
235 as per unix spec.
236
2374.16 Tue Aug 14 05:39:03 CEST 2012
238 - aio_statvfs was wromgly marked for wd emulation, causing
239 it to malfunction for paths.
240 - fix a crash in aio_fiemap, when used on ranges without any
241 extents.
242 - work around linux kernel bug (at least in 3.2): kernel might
243 trash fiemap input arguments.
244 - work around linux kernel bug (at least in 3.2): kernel does not
245 set FIEMAP_EXTENT_LAST on last segment.
246 - work around linux kernel bug (at least in 3.2): kernel silently
247 truncates segment count if a file.
248 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
249 to quick overview.
250 - splice can corrupt data.
251 - (libeio) remove pread/pwrite emulation.
252 - do not grow mmaped scalars in aio_read.
253 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
254 - provide pread/pwrite for win32, making it link again on native win32.
255
2564.15 Tue Apr 10 06:59:00 CEST 2012
257 - always include linux/types.h for fiemap, for compatibility to
258 ancient systems (Paul Howarth).
259 - experimental support for IO::AIO::splice and ::tee (no aio_...).
260 - provide SEEK_HOLE and SEEK_DATA, if available.
261 - work around (again!) an immensely stupid bug in RHEL, defining
262 autoconf macros in linux system headers (analysed by Paul Howarth).
263
2644.14 Sat Apr 7 02:45:18 CEST 2012
265 - fix stat structure usage on windows, which caused bogus stat results.
266 - (libeio) make readahead emulation behave more like actual readahead by never failing.
267 - new request aio_seek.
268 - new request aio_fiemap.
269 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
270
2714.12 Fri Dec 30 08:51:25 CET 2011
272 - realpath would return a random value if the name was too long,
273 instead of -1.
274 - port to c89.
275
2764.11 Mon Oct 10 00:24:11 CEST 2011
277 - libeio didn't compile on !linux (Paul Howarth).
278
2794.1 Sun Oct 9 10:24:11 CEST 2011
280 - IO::AIO did access uninitialised memory on unsuccessful stats.
281 - (libeio) added syncfs syscall wrapper.
282 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
283 - (libeio) support multiple indepenent working directories.
284 - applied speling corrections by Nicholas Bamber.
285 - tune treescan #threads and #outstanding requests a bit.
286 - reduce the number of file descriptors in use at any one time
287 in treescan, to avoid running out of them (and using too much ram).
288 - take advantage of working directoriy abstractions
289 in aio_scandir and treescan.
290 - reduce compiled size by ~10% by not inlining some key functionality.
291 - added --progress switch to treescan.
292
2934.0 Mon Jul 18 05:01:10 CEST 2011
294 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
295 see FORK BEHAVIOUR in manpage for details.
296 - passes testsuite on win32 now and may actually work
297 (activestate 5.10.1 / MSVC6, YMMV).
298 - (libeio) fix a deadlock where a wakeup signal could be missed when
299 a timeout occured at the same time.
300 - (libeio) added realpath.
301 - (libeio) added fallocate.
302 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
303 - (libeio) do not acquire any locks when forking.
304 - (libeio) use fewer time() syscalls when waiting for new requests.
305
3063.93 Wed Jun 29 23:44:18 CEST 2011
307 - ECB.H WAS MISSING.
308
3093.92 Wed Jun 29 14:45:41 CEST 2011
310 - ecb.h was missing.
311
3123.91 Wed Jun 29 13:24:42 CEST 2011
313 - (libeio) work around a Linux (and likely FreeBSD and other
314 kernels) bug where sendfile would not transfer all the requested
315 bytes on large transfers, using a heuristic.
316 - buggy sendfile caused aio_move/copy to sometimes fail for big
317 files (fortunately it checks that the whole file has been
318 transferred...)
319 - use libecb for higher performance and higher portability.
320 - (libeio) disable sendfile on darwin, it's too broken.
321 - disable fork tests on !linux, as only linux supports mixing
322 pthread and fork in perl.
323 - document the fact that fork doesn't work anymore when using
324 this module, on anything !GNU/Linux.
325 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
326 run on a 0.1MHz cpu. Or so.
327
3283.9 Fri May 27 02:43:47 CEST 2011
329 - (libeio) fix memory corruption in aio_readdirx for the flags
330 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
331 - add lots of newer POSIX and GNU/Linux-specific open
332 flags.
333
3343.8 Sun Mar 27 12:25:33 CEST 2011
335 - use nonstandard but maybe-working-on-bsd fork technique.
336 - support a max_idle value of 0.
337 - support setting of idle timeout value (IO::AIO::idle_timeout).
338
3393.72 Fri Feb 11 04:25:38 CET 2011
340 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
341 - aio_mknod always used a dev_t value of 0.
342 - new treescan option: --grep.
343 - add more S_IF macros, and major/minor/makedev "macros".
344
3453.71 Thu Dec 30 08:18:46 CET 2010
346 - the numerical result value passed to callbacks did not stringify
347 correctly, due to internal reuse and failure to reset the sv flags.
348 - actually test for posix_[mf]advise, as at least uClibc defines
349 _POSIX_ADVISORY_INFO without actually having any of the required
350 funcitonality. ugh.
351
3523.7 Mon Nov 1 23:00:34 CET 2010
353 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
354 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
355 - document the sad state of affairs w.r.t. pthread on many bsds.
356 - do not enable mmap on systems without _POSIX_MAPPED_FILES
357 (openbsd 4.8).
358 - do not leak memory in IO::AIO::mmap when the scalar already
359 had string-data.
360 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
361 them.
362 - cache the result IV, for a minor speedup in the common case.
363 - croak when an mmapped-scalar changes location, to detect
364 user-errors better.
365 - fix aio_readlink prototype.
366
3673.65 Wed Mar 31 02:45:05 CEST 2010
368 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
369 cut off long pathnames in aio_readlink (based on patch by
370 Rasmus Andersson).
371 - a double fork partially killed the event pipe (great testcase
372 by dormando). affects IO::AIO, BDB and Async::Interrupt.
373 - suck steve's dick and rename our symbols to avoid colliding
374 with nonstandard identifier spam on the broken os x pseudo-os.
375 affects IO::AIO and BDB.
376
3773.6 Mon Jan 11 00:43:39 CET 2010
378 - (libeio) more fixes for the freebsd/apple sendfile - broken by
379 manpage standards, but apparently correct accoridng to actual
380 kernel sources.
381 - add IO::AIO::mmap/munmap support.
382 - add IO::AIO::m(un)lockall support.
383 - clean up manpage.
384
3853.5 Thu Jan 7 21:25:04 CET 2010
386 - (liebio) fix freebsd sendfile (Vanilla Hsu).
387 - (libeio) also fix darwin sendfile that suffered from a similar bug.
388 - add aio_statvfs as interface to statvfs/fstatvfs.
389 - work around buggy symlink() on cygwin in the testsuite.
390 - wtf. freebsd-8.0 actually passes the testsuite! I knew
391 they could implement fork and semaphores one day! cheers!
392
3933.4 Sat Jan 2 15:13:04 CET 2010
394 - (libeio) max_poll_time was not properly converted to ticks.
395 - clarify cancel_subs description.
396 - IO::AIO::sendfile did not actually return the return value
397 from the sendfile call.
398 - implement aio_msync, aio_mtouch.
399 - (libeio) tentatively support darwin in sendfile.
400
4013.31 Thu Nov 12 02:14:29 CET 2009
402 - fix result status documentation of aio_copy, aio_move.
403 - speed up object creation considerably by avoiding
404 hash lookups.
405
4063.3 Wed Aug 5 13:52:58 CEST 2009
407 - use common::sense.
408 - use common schmorp.h header.
409 - allow integers (file descriptors) in addition to file handles.
410 - take advantage of linux' eventfd (but it seems slower on smp?).
411 - use poll not select on posix platforms.
412
4133.261 Wed Jul 1 10:11:51 CEST 2009
414 - more 0S X workarounds (patch by Tokuhiro Matsuno).
415
4163.26 Tue Jun 30 09:33:26 CEST 2009
417 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
418 try to work around this horribly broken OS in a somewhat hackish
419 way. might help other os's too.
420
4213.25 Sat Jun 27 05:18:26 CEST 2009
422 - added IO::AIO::fadvise and IO::AIO::sendfile.
423 - (libeio) replaced quicksort+insertion sort by a tuned radix
424 sort + insertion sort, resulting in comparable runtime (usually
425 faster) to the old version, but without any ill side effects on
426 degenerated (for quicksort) data.
427 - (libeio) correctly sort dirs by inodes if we have perfect type
428 knowledge and DIRS_FIRST is used.
429 - (libeio) internally the wrong DT_* constants were used, but no
430 known system has differing EIO_DT_*/DT_* values, so not an issue.
431 - removed a (harmless) assert that was left over on the code
432 but should not have been.
433 - use more correct types (change IO length from IV to VAL64,
434 which makes a difference on systems without 64 bit perls).
435
4363.23 Sat Jun 13 16:57:58 CEST 2009
437 - fix off-by-one bug in aio_readdir that was introduced in the
438 rushed 3.22 release.
439
4403.22 Sat Jun 13 15:32:40 CEST 2009
441 - speed up readdirx sort algorithm slightly.
442 - bin/treescan was missing from distro tarball.
443
4443.21 Fri Jun 12 18:45:53 CEST 2009
445 - new options --dirs and --files for treescan.
446 - install bin/treescan by default.
447 - (libeio) aio_readdir can now be cancelled while executing.
448 - fix a printf format string for 64 bit systems (could lead
449 to problems on big endian 64 bit systems).
450 - do not use qsort() but our own algorithm: glibc initialises
451 the whole locale and I/O subsystem inside qsort, causing
452 a stack overflow on 32 bit machines. The new sort uses much less
453 stack and is more than twice as fast in typical situations.
454
4553.2 Sun Jun 7 20:30:05 CEST 2009
456 - (libeio) pwrite emulation was even more flawed than intended and did
457 not restore the file offset.
458 - add aio_readdirx, which can return inode and filetype and sort
459 the names in various ways.
460 - unfortunately, utime, chmod, chown on an open file that has just
461 been written can easily block, which caused aio_copy to block the
462 process. no more!
463 - no longer rely on dst path in aio_copy when futime is available.
464
4653.19 Tue Apr 21 22:05:21 CEST 2009
466 - more perl 5.10 workarounds for aio_read and write.
467 - aio_write no longer modifies the sv (if possible).
468 - aio_read now works correctly with magic values.
469
4703.18 Sun Apr 19 21:17:32 CEST 2009
471 - better diagnostics when some aio_* functions get passed an illegal fh.
472 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
473
4743.17 Thu Nov 20 08:45:36 CET 2008
475 - (libeio) added aio_sync_file_range (untested).
476 - add aio_busy to @IO::AIO::AIO_REQ.
477
4783.16 Wed Oct 22 18:28:01 CEST 2008
479 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
480 part to improve portability to perl 5.8 (reported by szymon).
481
4823.15 Mon Oct 13 00:39:55 CEST 2008
483 - automatic removal of feeders was broken.
484 - (libeio) use a more robust method to detect whether a feeder
485 has added something to the group or not.
486
4873.1 Thu Oct 2 13:34:40 CEST 2008
488 - pre-deref the passed callback object, for increased speed
489 and decreased memory usage.
490 - call on_next_submit callback even for aio_group - impact unknown,
491 but seems more correct.
492 - $req->cb now returns the original callback.
493 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
494 requiring a thread switch.
495 - (libeio) status code of aio_futime and aio_utime was always passed 0.
496 - do some other ยต-optimisations.
497
4983.07 Sat Aug 2 16:06:13 CEST 2008
499 - do not include LIBS in autoconf tests.
500
5013.06 Tue Jul 15 12:41:32 CEST 2008
502 - move preadwritelock definition before it's first reference,
503 to make it compile again on broken platforms (they still exist)
504 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
505
5063.05 Thu Jun 19 23:23:52 CEST 2008
507 - work around perl overriding readdir etc. with thread-unsafe
508 (sic!) versions.
509
5103.04 Wed Jun 18 01:35:38 CEST 2008
511 - (libeio) fix eio_mknod, which confused it's arguments.
512 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
513 is stupid.
514 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
515 - (libeio) fix a bug that could potentially cause IO::AIO
516 not to get initialised properly.
517
5183.03 Thu May 29 05:33:30 CEST 2008
519 - (libeio) correctly call pthread_attr_destroy ().
520 - (libeio) work around broken bsd headers once more.
521 - reduce shared library size again by not including wrappers.
522 - max_outstanding could cause poll to enter a busy-waiting loop.
523 - document the new IO::AIO::poll_cb result value.
524
5253.02 Mon May 12 02:32:02 CEST 2008
526 - fix a memory leak on aio_readlink.
527 - bring back working fchmod.
528 - nop and busy now set result to 0.
529 - set errno to ENOMEM when allocation fails.
530
5313.01 Sun May 11 03:07:03 CEST 2008
532 - (libeio) make it compile on systems without readahead or readdir_r.
533 - (libeio) improve configure check for readahead availability.
534 - do not try to link against -lrt.
535 - use a separate configure script for IO::AIO (not the libeio one).
536
5373.0 Sun May 11 00:57:14 CEST 2008
538 - added bin/treescan to the distribution.
539 - switched to using libeio.
540 - LOTS OF INCOMPATIBLE CHANGES:
541 - remove signal functionality, it is not worth the effort.
542 - max_outstanding no longer returns the previous number of requests.
543 - poll_cb no longer returns number of requests.
544
5452.62 Sat Apr 26 13:59:33 CEST 2008
546 - port to solaris perls configured for old posix
547 (analysed by Jost Krieger).
548 - keep a reference to the perl filehandle object in aio_close,
549 so it doesn't get closed prematurely, leading to ugly races.
550
5512.61 Wed Apr 16 18:45:02 CEST 2008
552 - fix treescan output duplication and improve output ordering.
553 also display files given on the commandline.
554 - use a different algorithm for aio_close that is faster
555 and probably has even lower chances of blocking.
556 - do our own stack memory management for threads - linux
557 allocates outrageous amounts of VM (not so bad unless you
558 use mlockall...), which severely limits the number of threads
559 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
560 and 4096 * sizeof (long) (usually this is 16..64k).
561
5622.6 Sun Mar 30 08:28:11 CEST 2008
10 - added aio_sync. 563 - added aio_sync.
564 - added aio_pathsync.
565 - fix prototypes of (void) functions.
11 566
122.51 Sat Oct 6 16:04:54 CEST 2007 5672.51 Sat Oct 6 16:04:54 CEST 2007
13 - perlio isn't generally threadsafe, so aio_close could not work reliably. 568 - perlio isn't generally threadsafe, so aio_close could not work reliably.
14 aio_close now tries a safe hack that might not be that asynchronous 569 aio_close now tries a safe hack that might not be that asynchronous
15 (see the manpage for details). 570 (see the manpage for details).
