new snapshot available: coreutils-8.9.77-4e9ab7 |

Here's a snapshot of what should soon be tagged as coreutils-8.10.
I expect to release 8.10 on Friday, so any testing you can do
between now and then would be most welcome.
Since this changes how "cp" handles sparse files, it is particularly
useful to build and run the tests on different types of file systems.
You'll see significant benefit when copying sparse files on recent linux
kernels (2.6.27 or newer) when using a source file system that supports
the FIEMAP ioctl, mainly ext4, btrfs, xfs, ocfs2, gfs2. ext2 and ext3
are supposed to have FIEMAP support, too, but I haven't tested those.
If you test with btrfs, you should expect one or two test failure unless
you're using the very latest from fedora rawhide, in which case you'll
see only 1 test failure (cp/sparse-fiemap; I'll work around that tomorrow).

Here's the NEWS so far:
---------------------------------------------------------------------------
** Bug fixes
du would abort with a failed assertion when two conditions are met:
part of the hierarchy being traversed is moved to a higher level in the
directory tree, and there is at least one more command line directory
argument following the one containing the moved sub-tree.
[bug introduced in coreutils-5.1.0]
join --header now skips the ordering check for the first line
even if the other file is empty. [bug introduced in coreutils-8.5]
rm -f no longer fails for EINVAL or EILSEQ on file systems that
reject file names invalid for that file system.
uniq -f NUM no longer tries to process fields after end of line.
[bug introduced in coreutils-7.0]
** New features
cp now copies sparse files efficiently on file systems with FIEMAP
support (ext4, btrfs, xfs, ocfs2). Before, it had to read 2^20 bytes
when copying a 1MiB sparse file. Now, it copies bytes only for the
non-sparse sections of a file. Similarly, to induce a hole in the
output file, it had to detect a long sequence of zero bytes. Now,
it knows precisely where each hole in an input file is, and can
reproduce them efficiently in the output file. mv also benefits
when it resorts to copying, e.g., between file systems.
join now supports -o 'auto' which will automatically infer the
output format from the first line in each file, to ensure
the same number of fields are output for each line.
** Changes in behavior
join no longer reports disorder when one of the files is empty.
This allows one to use join as a field extractor like:
join -a1 -o 1.3,1.1 - /dev/null
