4.81 Tue 20 Feb 2024 07:38:35 CET
- work around a bug in musl w.r.t to O_SEARCH and use EIO_O_PATH instead,
vertifying the semantics against the subset of O_PATH and O_SEARCH
(based on a report by Steve Dondley).
- aio_copy now tries to preallocate the destination file.
- fexecve configure test used the wrong püointer type (patch by Paul Howarth).
4.80 Sat 01 Apr 2023 04:13:37 CEST
- remove long obsolete "paths must be absolute" text in aio_open/stat
descriptions.
- another workaround for the low-quality musl libc.
- add lots of missing functions to @EXPORT_OK.
4.76 Tue Jul 27 20:45:01 CEST 2021
- add autoconf test for siginfo_t, which is, of course, not
available on windows (reported by Peter Petky).
- disable syscalls on solaris, as perl seems to provide an
incompatible syscall prototype that clashes with sys/syscall.h.
- add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and
MAP_UNINITIALIZED.
4.75 Wed Dec 30 08:44:55 CET 2020
- removed leftover debug output from treescan.
- added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*,
FSCONFIG_*, MOUNT_ATTR_* constants.
4.74 Tue Dec 29 16:19:28 CET 2020
- added pidfd_open, pidfd_getfd and pidfd_send_signal functions.
- rework bin/treescan to avoid recursion. This fixes two bugs
where a deep directory traversal or a lot of command line
arguments could cause it to crash.
- added (but not documented) open_tree, AT_* and move_mount flags.
- support defining syscall numbers in gendef0.
4.73 Fri Dec 4 02:08:37 CET 2020
- def0.h was not uptodate, running into musl problems
(reported by B Fraser).
- IO::AIO::splice and IO::AIO::tee didn't properly return
64 bit values.
- added IO::AIO::accept4.
- add various F_SEAL related fcntl constants.
- removed experimental marker for fdlimit functions.
- fiemap now includes the last segment even if it overflows
the end offset, which is arguably the correct behaviour.
4.72 Wed Apr 3 04:56:03 CEST 2019
- (libeio) if fd 0 is available do not use it for aio_wd, as it
collides with IO::AIO::CWD.
- added IO::AIO::memfd_create.
- correctly include <sys/uio.h> in the vmsplice test.
- reduce codesize by ~7% on amd64 by declaring more functions
as noinline.
- documentation fixes and updates.
- experimental and undocumented preliminary support for synchronous statx.
4.71 Sun Mar 10 13:09:26 CET 2019
- due to an error in the linux manpages, the configure tests
for readahead, sync_file_range, splice etc. failed. This has been fixed.
4.7 Mon Mar 4 11:28:13 CET 2019
- majorly speed up scandir for the very special case of a non-POSIX
filesystem that nevertheless reports valid dt_type information.
The only known filesystem of this type is currently btrfs, which
didn't get it's act together to implement POSIX semantics in all
these years, and I am tired of waiting.
- add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
- neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
were detected by autoconf.
4.6 Sat Aug 25 21:58:36 CEST 2018
- removed non-portable C++ syntax from eio.c.
- try to fix readdir tests on cygwin spuriously failing.
4.5 Wed Aug 1 00:23:55 CEST 2018
- aio_mtouch touch all pages as requested, not just the first page in most cases.
- new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
and MREMAP_FIXED.
- add O_ACCMODE.
- add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
4.4 Tue Feb 20 07:54:12 CET 2018
- new aio_slurp request.
- add (experimental) IO::AIO::eventfd and timerfd* function.
- add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
- point out that aio_copy overwrites existing files.
- removed filesystem magic number table from aio_statvfs docs as
statvfs doesn't actually return this info at all (statfs does).
- add a bunch of (mostly linux-specific) constants for use in ioctls
(see aio_ioctl docs).
- treescan now has a proper manpage and useful --help output.
- new option --sync in treescan, to sync everything in a subtree.
4.34 Sun May 1 19:18:24 CEST 2016
- def0.h was not properly generated during previous release, causing
compile errors on various platforms.
- major/minor were accidentally switched (reported by Alexander Lishenyuk).
- removed duplicate definition of MAP_HUGETLB, that was found due to
a bug in Perl::Tidy (testcase by alaska332@gmail.com).
- added (untested!) aio_fcntl, aio_ioctl requests.
- (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
as manpages-dev originally claimed.
4.33 Mon Jan 18 12:50:10 CET 2016
- add IO::AIO::pipe2 function.
- added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
constants.
- added support for O_TMPFILE and O_PATH constants.
- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
consdtants, whether they can be sensibly used or not.
- use NO_INIT where applicable.
- update libecb.
- added stability canary support.
- updated linux super magic table to 4.3.3.
4.32 Wed Feb 11 20:32:11 CET 2015
- replace off_t by STRLEN where appropriate, should not result in
user-visible changes.
- update ecb.h for C11 compatibility.
4.31 Tue Jun 3 03:29:27 CEST 2014
- work around more 5.20 bugs. backwards compatibility my ass.
4.3 Fri Apr 11 06:22:38 CEST 2014
- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
in 5.18. What's so attractive about giving a shit about backwards
compatibility - I will never understand.
4.2 Sat Jan 25 01:13:14 CET 2014
- aio_group could corrupt memory because it didn't restore
the stack after req_submit.
- be more careful on (e.g. permission) errors in bin/treescan.
- work around changes in ExtUtils::MakeMaker.
- (libeio) implement aio_realpath for win32.
- (xthread) work around compile time bugs in ptw32.
- added IO::AIO::pipesize.
- (libecb) insignificant update.
4.19 Sun Jan 6 12:47:26 CET 2013
- avoid endless loop in fiemap with some XFS files.
- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
and call rename/rmdir instead of renameat/unlinkat.
4.18 Thu Oct 11 07:01:26 CEST 2012
- fix unintended xthread_create by intentionalising it :)
4.17 Thu Oct 11 05:19:47 CEST 2012
- rename aio_fallocate to aio_allocate, to match documentation.
- add list of linux fsid values to aio_statvfs docs.
- work around (again!) an immensely stupid bug in RHEL, defining
autoconf macros in linux system headers (analysed by Paul Howarth).
4.14 Sat Apr 7 02:45:18 CEST 2012
- fix stat structure usage on windows, which caused bogus stat results.
- (libeio) make readahead emulation behave more like actual readahead by never failing.
- new request aio_seek.
- new request aio_fiemap.
- autogenerate the #ifdef/#define 0 blocks for symbols we export.
4.12 Fri Dec 30 08:51:25 CET 2011
- realpath would return a random value if the name was too long,
instead of -1.
- port to c89.
4.11 Mon Oct 10 00:24:11 CEST 2011
- libeio didn't compile on !linux (Paul Howarth).
4.1 Sun Oct 9 10:24:11 CEST 2011
- IO::AIO did access uninitialised memory on unsuccessful stats.
- (libeio) added syncfs syscall wrapper.
- (libeio) fix memory corruption in aio_readdirx for the flags
combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
- add lots of newer POSIX and GNU/Linux-specific open
flags.
3.8 Sun Mar 27 12:25:33 CEST 2011
- use nonstandard but maybe-working-on-bsd fork technique.
- support a max_idle value of 0.
- support setting of idle timeout value (IO::AIO::idle_timeout).
3.72 Fri Feb 11 04:25:38 CET 2011
- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
- aio_mknod always used a dev_t value of 0.
- new treescan option: --grep.
- add more S_IF macros, and major/minor/makedev "macros".
3.71 Thu Dec 30 08:18:46 CET 2010
- the numerical result value passed to callbacks did not stringify
correctly, due to internal reuse and failure to reset the sv flags.
- actually test for posix_[mf]advise, as at least uClibc defines
_POSIX_ADVISORY_INFO without actually having any of the required
funcitonality. ugh.
3.7 Mon Nov 1 23:00:34 CET 2010
- implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
- document the sad state of affairs w.r.t. pthread on many bsds.
- do not enable mmap on systems without _POSIX_MAPPED_FILES
(openbsd 4.8).
- do not leak memory in IO::AIO::mmap when the scalar already
had string-data.
- add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
them.
- cache the result IV, for a minor speedup in the common case.
3.65 Wed Mar 31 02:45:05 CEST 2010
- actually use PATH_MAX instead of NAME_MAX for readlink, as to not
cut off long pathnames in aio_readlink (based on patch by
Rasmus Andersson).
- a double fork partially killed the event pipe (great testcase
by dormando). affects IO::AIO, BDB and Async::Interrupt.
- suck steve's dick and rename our symbols to avoid colliding
with nonstandard identifier spam on the broken os x pseudo-os.
affects IO::AIO and BDB.
3.6 Mon Jan 11 00:43:39 CET 2010
- (libeio) more fixes for the freebsd/apple sendfile - broken by
manpage standards, but apparently correct accoridng to actual
kernel sources.
- add IO::AIO::mmap/munmap support.
- add IO::AIO::m(un)lockall support.
- clean up manpage.
3.5 Thu Jan 7 21:25:04 CET 2010
- (liebio) fix freebsd sendfile (Vanilla Hsu).
- (libeio) also fix darwin sendfile that suffered from a similar bug.
- add aio_statvfs as interface to statvfs/fstatvfs.
- work around buggy symlink() on cygwin in the testsuite.
- wtf. freebsd-8.0 actually passes the testsuite! I knew
they could implement fork and semaphores one day! cheers!
3.4 Sat Jan 2 15:13:04 CET 2010

- use common::sense.
- use common schmorp.h header.
- allow integers (file descriptors) in addition to file handles.
- take advantage of linux' eventfd (but it seems slower on smp?).
- use poll not select on posix platforms.
3.19 Tue Apr 21 22:05:21 CEST 2009
- more perl 5.10 workarounds for aio_read and write.
- aio_write no longer modifies the sv (if possible).
- aio_read now works correctly with magic values.
3.18 Sun Apr 19 21:17:32 CEST 2009
- better diagnostics when some aio_* functions get passed an illegal fh.
- try to avoid crashes due to incompatible 5.10 API changes. grmbl.
3.17 Thu Nov 20 08:45:36 CET 2008
- (libeio) added aio_sync_file_range (untested).
- add aio_busy to @IO::AIO::AIO_REQ.
3.16 Wed Oct 22 18:28:01 CEST 2008
- use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
part to improve portability to perl 5.8 (reported by szymon).
3.15 Mon Oct 13 00:39:55 CEST 2008
- automatic removal of feeders was broken.
- (libeio) use a more robust method to detect whether a feeder
have a larger range then.
- shared code between BDB and IO::AIO.
- aio_busy was completely broken. now fixed.
- readahead emulation now returns something.
- correctly set errno to ENOSYS on unimplemented functions
(should never happen, though).
- large changes to make it partially compile and run on win32,
but win32 lacks too much functionality, and perl overrides way
too many functions with crashing versions.
2.33 Tue Jan 23 23:55:41 CET 2007
- fix install path (Andreas J. Koenig).
2.32 Mon Jan 22 16:56:23 CET 2007
- added aio_rmtree.
- wow, aio_mkdir was missing.
- aio_load did return undef on error, not -1.
- use prefixexp not prefix in autoconf.pm
(suggested by ... rt.cpan.org unreachable).
- avoid installing autoconf.pm.

- added aio_load.
2.3 Sat Dec 23 05:48:07 CET 2006
- fix off-by-one bug in aio_read, causing memory corruption
or crashes.
2.21 Fri Dec 22 05:03:38 CET 2006
- minor doc updates.
- minor cleanups.
- IO::AIO::poll returns request count.
- undocumented and unfinished async-signal-reporting.
2.2 Tue Oct 31 00:31:00 CET 2006
- minor doc updates.
- added aio_readlink.
- properly zero-terminate aio_read buffer.
- fix aio_read/write with nonzero dataoffset.
- reduced size of aio request structure.
- better diagnostics when pathnames etc. are not byte-encoded;
do not leak request in that case, either.
2.1 Sun Oct 29 02:01:57 CET 2006
- INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
- fix a bug in aio_move where it would fail everytime
it would have to copy files manually.
- doc updates.
- start threads only on (very low) demand.
- end superfluous threads automatically after 10s idling.
- add IO::AIO::max_idle to control this.
- some tuning applied to random places.
- add aio_mknod.
- better error checking when ENOMEM.
- hopefully fix mem and dirp leaks on fork.
- warn about broken perl malloc.
- compiles on cygwin (but pread is broken on cygwin
which is not detected by autoconf, so you have to
edit autoconf/config.h yourself to enable emulation).
1.8 Sat Jun 24 22:20:44 CEST 2006
- add and/or document aio_rename, aio_link, aio_symlink and aio_move.
1.73 Wed Mar 1 22:49:32 CET 2006
- codename "jost"
- AIX/Solaris(?) aren't being helpful again, hardcode a value
for NAME_MAX and drive with your eyes closed (reported by
wcooley@nakedape.cc).
1.72 Thu Feb 2 00:40:44 CET 2006
- another minor bug in aio_scandir, again, the callback was called
twice when the directory can't be stat'ed.
1.71 Mon Dec 26 20:20:03 CET 2005
- grr, another minor bug in aio_scandir, this time resulting
in a runtime error.
1.7 Mon Dec 26 19:29:48 CET 2005
- aio_scandir errornously called callback twice in some cases.
- added AnyEvent example.
1.61 Wed Sep 7 19:40:42 CEST 2005
- no longer include $Config{libs}, as distros include too much
garbage in there that is not installed on typical systems
(for example, debian links perl against -lgdbm and many more
libraries despite perl not needing it, slowing down startup and
wasting memory).
