* src/split.c (main): Use stat.st_size only for regular files.
Samuel Thibault reported in http://bugs.gnu.org/11424 that the
/dev/zero-splitting tests would appear to infloop on GNU/Hurd,
because /dev/zero's st_size is LONG_MAX. It was only a problem
when using the --number (-n) option.
* NEWS (Bug fixes): Mention it.
This bug was introduced with the --number option, via
commit v8.7-25-gbe10739

... i.e., don't use the getpw* functions.
Before this change, running groups or id with no user name argument
would include a group name or ID from /etc/passwd. Thus, under unusual
circumstances (default group is changed, but has not taken effect for a
given session), those programs could print a name or ID that is neither
real nor effective.
To demonstrate, run this:
echo 'for i in 1 2; do id -G; sleep 1.5; done' \
|su -s /bin/sh ftp - &
sleep 1; perl -pi -e 's/^(ftp:x:\d+):(\d+)/$1:9876/' /etc/passwd
Those id -G commands printed the following:
50
50 9876
With this change, they print this:
50
50
Similarly, running those programs set-GID could make them
print one ID too many.
* src/group-list.c (print_group_list): When username is NULL, pass

With the "--relative --symbolic" options, ln computes the relative
symbolic link for the user.
So, ln works just as cp, but creates relative symbolic links instead
of copying the file.

Surprise! "du -x non-DIR" would print nothing.
Note that the problem arises only when processing a non-directory
specified on the command line. Not surprisingly, "du -x" still
works as expected for any directory argument.
When performing its same-file-system check, du may skip an entry
only if it is at fts_level 1 or greater. Command-line arguments
are at fts_level == 0 (FTS_ROOTLEVEL).
* src/du.c (process_file): Don't use the top-level FTS->fts_dev
when testing for --one-file-system (-x). It happens to be valid

Like the optimization to avoid always-failing getfilecon calls,
this change avoids always-failing queries for whether a file has
a nontrivial ACL and for whether a file has certain "capabilities".
When such a query fails for one file (indicating no support), we know it
will always fail that way for the affected device. With this change, we
have thus eliminated nearly all failing-unsupported getxattr syscalls.
* src/ls.c (has_capability) [!HAVE_CAP]: Set errno to ENOTSUP.
(errno_unsupported): Expand the list of E* errno values to match
that of lib/acl-internal.h's ACL_NOT_WELL_SUPPORTED macro.
(file_has_acl_cache, has_capability_cache): New functions.
(gobble_file): Use them in place of non-caching ones.
* NEWS (Improvements): Mention it.
Suggested by Sven Breuner in
http://thread.gmane.org/gmane.comp.gnu.coreutils.general/2187
While eliminating most getfilecon calls saved about 33%,
eliminating these other calls can save almost all of the
remaining ~67% cost, on some remote file systems.

dd now accepts the count_bytes and skip_bytes input flag and the

'skip_bytes' iflag is used. Compute max_records and max_bytes when
'count_bytes' iflag is used. Compute seek_records and seek_bytes
when 'seek_bytes' oflag is used.
(skip_via_lseek): Use new 'bytes' parameter and handle potential
'records' equals to zero. Update the bytes parameter when called with
'fdesc' equal to STDOUT_FILENO. Update the header comments.

But only when both A and B were hard links to the same symlink.
* src/copy.c (same_file_ok): Handle another special case: the one
in which we are moving a symlink onto a hard link to itself.
In this case, we must explicitly tell the caller to unlink the
source file. Otherwise, at least the linux-3.x kernel rename
function would do nothing, as mandated by POSIX 2008.

Normally, mv detects a few subtle cases in which proceeding with a
same-file rename would, with very high probability, cause data loss.
Here, we have found a corner case in which one of these same-inode

corner case.

* NEWS (New programs): Move this small section to the top.
(df): Reword entry, from Pádraig Brady.
|

On systems with recent kernel/tools, a symlink from /etc/mtab to
/proc/mounts, and a by-UUID mount (i.e., soon, nearly everyone),
you will see something like the following when running "df -hT":
(this has been truncated to fit in a width-limited ChangeLog file)
Filesystem Type Siz...
rootfs rootfs 11G
udev devtmpfs 3.8G
tmpfs tmpfs 774M
/dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66 ext4 11G
tmpfs tmpfs 1.6G
/dev/sda2 ext3 494M
/dev/sda5 ext4 12G
/dev/sda6 ext4 9.9G
Contrast that with what we're used to seeing (modulo the
two entries mounted on "/", which is a separate problem):
Filesystem Type Size Used Avail Use% Mounted on
rootfs rootfs 11G 1.9G 8.0G 19% /
udev devtmpfs 3.8G 0 3.8G 0% /dev
tmpfs tmpfs 774M 376K 774M 1% /run
/dev/sda3 ext4 11G 1.9G 8.0G 19% /
tmpfs tmpfs 1.6G 8.0K 1.6G 1% /run/shm
/dev/sda2 ext3 494M 78M 392M 17% /boot
/dev/sda5 ext4 12G 7.6G 3.7G 68% /usr
/dev/sda6 ext4 9.9G 6.6G 2.8G 71% /var
When that long /dev/disk/by-uuid/... name is merely a symlink
to a much shorter (and often more useful) device name like
"/dev/sda3", and when it's part of a listing of all file systems,
I would much prefer to see only the latter. Similarly, when using
an encrypted root file system, you would see a name like
/dev/mapper/luks-828fc648-9f30-43d8-a0b1-f7196a2edb66 pointing
to say, /dev/dm-0, I prefer the shorter name.
I.e., if I explicitly run
"df -hT /dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66",
then, it's fine -- and expected -- to print to the long name.
It was explicitly given. However, with no non-option argument,
df should print the shorter name. Note that performing this
translation at a lower level (via a change to gnulib's mountlist.c)
would make it impossible to distinguish those two cases.
* src/df.c: Include "canonicalize.h".
(get_dev): Add a parameter, telling when we're in process-all-
mount-points mode; update all callers. When true, resolve
UUID-suffixed symlinks.

Starting with commit adc30a83, when using --color, ls inhibited
interrupts to avoid corrupting the state of an output terminal.
However, for very large directories, that inhibition rendered ls
uninterruptible for too long, including a potentially long period
even before any output is generated.
* src/ls.c: Two phases of processing are time-consuming enough that
they can provoke this: the readdir loop and the printing loop. The
printing was supposed to be covered by a call to process_signals in
(print_name_with_quoting): ... but that call was mistakenly guarded
by a condition that might be false for many or even all files being
processed. Call process_signals unconditionally.
