-------------------------------
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.

- drop patch-libeio_ecb.h
It was "Use __builtin_unreachable on Clang instead of the broken C11 hack.",
and upstream put the equivalent change.

(upstream)
- Update to 4.32
-----------------
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.
- Add comment on patch, picking from cvs log
(upstream)
- Update 4.18 to 4.31
-------------------
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.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
Revision history for IO::AIO
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 a bug in btrfs' FIEMAP ioctl implementation.
- work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
as per unix spec.
4.16 Tue Aug 14 05:39:03 CEST 2012
- aio_statvfs was wromgly marked for wd emulation, causing
it to malfunction for paths.
- fix a crash in aio_fiemap, when used on ranges without any
extents.
- work around linux kernel bug (at least in 3.2): kernel might
trash fiemap input arguments.
- work around linux kernel bug (at least in 3.2): kernel does not
set FIEMAP_EXTENT_LAST on last segment.
- work around linux kernel bug (at least in 3.2): kernel silently
truncates segment count if a file.
- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
to quick overview.
- splice can corrupt data.
- (libeio) remove pread/pwrite emulation.
- do not grow mmaped scalars in aio_read.
- add FALLOC_FL_PUNCH_HOLE and document fallocate.
- provide pread/pwrite for win32, making it link again on native win32.
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
4.11 to 4.15.
Upstream changes:
4.15 Tue Apr 10 06:59:00 CEST 2012
- always include linux/types.h for fiemap, for compatibility to
ancient systems (Paul Howarth).
- experimental support for IO::AIO::splice and ::tee (no aio_...).
- provide SEEK_HOLE and SEEK_DATA, if available.
- 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.
Changes from previous:
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) set thread name on linux (ps -L/Hcx, top, gdb).
- (libeio) support multiple indepenent working directories.
- applied speling corrections by Nicholas Bamber.
- tune treescan #threads and #outstanding requests a bit.
- reduce the number of file descriptors in use at any one time
in treescan, to avoid running out of them (and using too much ram).
- take advantage of working directoriy abstractions
in aio_scandir and treescan.
- reduce compiled size by ~10% by not inlining some key functionality.
- added --progress switch to treescan.
4.0 Mon Jul 18 05:01:10 CEST 2011
- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
see FORK BEHAVIOUR in manpage for details.
- passes testsuite on win32 now and may actually work
(activestate 5.10.1 / MSVC6, YMMV).
- (libeio) fix a deadlock where a wakeup signal could be missed when
a timeout occured at the same time.
- (libeio) added realpath.
- (libeio) added fallocate.
- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
- (libeio) do not acquire any locks when forking.
- (libeio) use fewer time() syscalls when waiting for new requests.
3.93 Wed Jun 29 23:44:18 CEST 2011
- ECB.H WAS MISSING.
3.92 Wed Jun 29 14:45:41 CEST 2011
- ecb.h was missing.
3.91 Wed Jun 29 13:24:42 CEST 2011
- (libeio) work around a Linux (and likely FreeBSD and other
kernels) bug where sendfile would not transfer all the requested
bytes on large transfers, using a heuristic.
- buggy sendfile caused aio_move/copy to sometimes fail for big
files (fortunately it checks that the whole file has been
transferred...)
- use libecb for higher performance and higher portability.
- (libeio) disable sendfile on darwin, it's too broken.
- disable fork tests on !linux, as only linux supports mixing
pthread and fork in perl.
- document the fact that fork doesn't work anymore when using
this module, on anything !GNU/Linux.
- increase timeout in t/04_fork.t, as too many CPAN-tester setups
run on a 0.1MHz cpu. Or so.
3.9 Fri May 27 02:43:47 CEST 2011
- (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.
- croak when an mmapped-scalar changes location, to detect
user-errors better.
- fix aio_readlink prototype.
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.
sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!
Collection.
The Perl 5 module IO::AIO implements asynchronous I/O using whatever
means the operating system supports. It is implemented as an interface
to libeio.
