* src/id.c (usage): Remove 'name' from the synopsis,
implying that one can also specify by user ID.
(main): Like chown(1), call parse_user_spec() to implement
user name or ID lookup with appropriate precedence.
* doc/coreutils.texi (id invocation): Mention that
a user ID is supported and how '+' affects lookup order.
* tests/misc/id-groups.sh: Remove test now subsumed into...
* tests/misc/id-uid.sh: New test covering new interface.
* tests/local.mk: Rename the test.
* NEWS: Mention the new feature.

* src/group-list.h (print_group_list): Add a parameter for the
delimiter of type char.
* src/group-list.c (print_group_list): Likewise, and use it instead
of a white space character to delimit the group entries.
* src/groups.c (main): Pass white space character to print_group_list().
* src/id.c (longopts): Add array element for the new long option.
(usage): Document the new option. While at it, fix the alignment
of the descriptions to match that of HELP_OPTION_DESCRIPTION.
(main): Define the bool flag opt_zero indicating the use of the
new option. In the getopt_long loop, handle it.
Output an error diagnostic in the case the --zero option has been
specified together with the default format.
In the case of -gG, pass either a NUL or a white space character to
print_group_list() - depending on the above new flag.
Likewise change the printing of the final newline character: output
a NUL instead if the --zero option has been specified.
* doc/coreutils.texi (id invocation): Document the new option.
While at it, move the @exitstatus macro down after the macro
@primaryAndSupplementaryGroups in order to be consistent with
other texinfo documents.
(groups invocation): Move @exitstatus down after the macro
@primaryAndSupplementaryGroups here, too.
* tests/misc/id-zero.sh: Add new test exercising the new option.
* tests/local.mk (all_tests): Reference it.

If there is an error reading a directory that was referenced
through recursion, rather than directly on the command line,
then exit with the "less serious" exit code, rather than the
"serious" exit code reserved for command line arguments.
This issue was introduced in commit v5.2.1-1908-gb58dea5

is false for directories being recursed into.
* NEWS: Mention the bug fix.

This new option can be used to find directories with a huge
amount of files. The GNU find utility has the printf format
"%h" which prints the number of entries in a directory, but
this is non-cumulative and doesn't handle hard links.
* src/du.c (struct duinfo): Add new member for counting inodes.
(duinfo_init): Initialize inodes member with Zero.
(duinfo_set): Set inodes counter to 1.
(duinfo_add): Sum up the 2 given inodes counters.
(opt_inodes): Add new boolean flag to remember if the --inodes
option has been specified.
(INODES_OPTION): Add new enum value to be used ...
(long_options): ... here.
(usage): Add description of the new option.
(print_size): Pass inodes counter or size to print_only_size,
depending on the inodes mode.
(process_file): Adapt threshold handling: with --inodes, print or
elide the entries according to the struct member inodes.
(main): Add a case for accepting the new INODES_OPTION.
Print a warning diagnostic when --inodes is used together with the
option --apparent-size or -b.
Reset the output_block_size to 1 ... and thus ignoring the
options -m and -k.
* tests/du/inodes.sh: Add a new test.
* tests/local.mk (all_tests): Mention it.
* doc/coreutils.texi (du invocation): Document the new option.
* NEWS: Mention the new option.

src/copy.c (copy_internal): Use rmdir() rather than unlink()
when the source is a directory, so that empty directories
are replaced in the destination as per POSIX.

* src/dd.c (STATUS_NONE): Simplify the enum so that
it's more general than just suppressing transfer counts.
Then test this in all locations where non fatal diagnostics
are output.

Enable showing of file SMACK security with '-Z' command-line switch
if SMACK is enabled. Showing SMACK context of a file does not strictly
require SMACK to be enabled but this required to make choice whether to
show SELinux or SMACK security context.
* src/ls.c (getfilecon_cache): Retrieve SMACK context if available.
(gobble_file): Handle SMACK context similarly to SELinux context.
* src/local.mk: Link lsl with libsmack.
* NEWS: Mention the new feature.
* .mailmap: Merge the Author's 2 email addresses.

This is consistent with the documented interface and
avoids any ambiguity in a user thinking that stdbuf without options
might reset to a "standard" buffering setup.
* src/stdbuf.c (set_libstdbuf_options): Indicate with the return value
whether any env variables were actually set.
(main): Fail unless some env variables were set.
* tests/misc/stdbuf.sh: Ensure this constraint is enforced.
* NEWS: Mention the small change in behavior.

For a file of size 1234 bytes, commit ca9aa759 had the side effect
of changing 'stat -c "%'s" file' from outputting "?s" to the nicer
"1,234", depending on locale. This is worth mentioning in the NEWS.
Resolves part of http://bugs.gnu.org/14556.
* NEWS: Mention 8.7 improvement in stat.
* cfg.mk (old_NEWS_hash): Adjust accordingly.

* src/od.c (PRINT_FIELDS): Declare "i" to be of type uintmax_t, so that
the numerator in the expression for "next_pad" does not overflow.
(print_named_ascii): Likewise.
(print_ascii): Likewise.
Bug introduced via commit v6.12-42-g20c0b87.

* src/split.c (line_bytes_split): Rewrite to only buffer
when necessary. I.E. only increase the buffer when we've
already lines output in a split and we encounter a line
larger than the input buffer size, in which case a hold
buffer will be increased in increments of the input buffer size.
(lines_rr): Use the more abstract xalloc_die() just like
we did in line_bytes_split(), rather than explicitly
printing the "memory exhausted" message and exiting.
* tests/split/line-bytes.sh: Add a new test for this
function which previously had no test coverage.

This fixes Bug#14371, reported by Killer Bassist.
* NEWS: Document this.
* src/mkdir.c (struct mkdir_options): Remove member ancestor_mode.
New member umask_value. All uses changed.
* src/mkdir.c (make_ancestor): Fix umask assumption.
* src/mkdir.c, src/mkfifo.c, src/mknod.c (main):
Leave umask alone. This requires invoking lchmod after creating
the file, which introduces a race condition, but this can't be
avoided on hosts with "POSIX" default ACLs, and there's no easy
way with network file systems to tell what kind of host the
directory is on.
* tests/local.mk (all_tests): Add tests/mkdir/p-acl.sh.
* tests/mkdir/p-acl.sh: New file.

The --retry option is indeed useful for both following modes
by name and by file descriptor. The difference is that in the
latter case, it is effective only during the initial open.
As a regression of the implementation of the inotify support,
tail -f --retry would immediately exit if the given file is
inaccessible.
* src/tail.c (usage): Change the description of the --retry option:
remove the note that this option would mainly be useful when
following by name.
(main): Change diagnosing dubios uses of --retry option:
when the --retry option is used without following, then issue
a warning that this option is ignored; when it is used together
with --follow=descriptor, then issue a warning that it is only
effective for the initial open.
Disable inotify also in the case when the initial open in tail_file()
failed (which is the actual bug fix).
* init.cfg (retry_delay_): Pass excess arguments to the test function.
* tests/tail-2/retry.sh: Add new tests.
* tests/local.mk (all_tests): Mention it.

With --suppress-matched, the lines that match the pattern will not be
printed in the output files. I.E. the first line from the second
and subsequent splits will be suppressed.
* src/csplit.c: process_regexp(),process_line_count(): Don't output the
matched lines. Since csplit includes "up to but not including" matched
lines in each split, the first line (in the next group) is the matched
line - so just skip it.
main(): Handle new option.
usage(): Mention new option.

* tests/misc/csplit-suppress-matched.pl: New test script.
* tests/local.mk: Reference the new test.

of the symlink name when canonicalizing, as we want to avoid
dereferencing the final component.

Reservoir sampling optimizes selecting K random lines from large or
unknown-sized input: http://en.wikipedia.org/wiki/Reservoir_sampling
Note this also avoids reading any input when -n0 is specified.
* src/shuf.c (main): Use reservoir-sampling when the number of output
lines is known, and the input size is large or unknown.
(input_size): A new function to get the input size for regular files.
(read_input_reservoir_sampling): New function to read lines from input,
keeping only K lines in memory, replacing lines with decreasing prob.

Like any other pseudo file system, df should show rootfs only
when the -a option is specified, i.e. specifying -trootfs alone
is not sufficient. As the rootfs entry is now elided by the
general deduplication in filter_mount_list (commit v8.20-103-gbb116d3),
all other references to rootfs can be removed again.
* src/df.c (show_rootfs): Remove global variable.
(ROOTFS): Remove constant.
(filter_mount_list): Remove case to handle rootfs specially.
(main): In the case for handling the -t option, remove setting
of the show_rootfs variable.
* tests/df/skip-rootfs.sh: Adapt the test case "df -t rootfs":
the rootfs file system must not be printed (because no -a).
* doc/coreutils.texi (df invocation): Correct the documentation
about eliding mount entries: it is not the first occurrence of
the the device which wins, but now rather the entry with the
shortest mount point name. Also adapt the description about
eliding pseudo file system types like rootfs.

In addition to the previous 64 bit guards we've placed in longlong.h
there are additional _LP64 guards required for mips with -mcpu >= 3,
to avoid a build failure (http://bugs.gnu.org/13353) and on sparc
with -mcpu >= v9 in 32 bit mode where for example,
`factor 2123123123123123123123` would go into an infinite loop.
Since factor.c currently operates on uintmax_t, we restrict the use
of the assembly in longlong.h to when 'long' has the same width, to
provide a more general guard for this code.
* src/factor.c: Restrict the use of longlong.h assembly code,
to when the width of intmax_t == long.
* src/longlong.h: Remove the previous _LP64 guards to avoid
divergence from GMP's longlong.h
* NEWS: Adjust the info on build and runtime fixes.

This allows efficient processing of multiple files,
while also increasing compatibility with BSD's readlink(1).
We also add the -z, --zero option to delimit output items
with the NUL character which disambiguates output in the
presence of '\n' characters.
* src/readlink.c (usage): Add the --zero description,
and also adjust the description of --no-newline accordingly.
(main): Handle the -z option and iterate over multiple arguments.
Also as in commit v8.15-24-g9d46b25 we use fputs() and putchar()
rather than printf() for performance reasons.
* doc/coreutils.texi (readlink invocation): Document the
new --zero option, adjust the --no-newline description, and

Both Debian and Ubuntu builds of coreutils 8.20 hang while running the
test suite on powerpc, which is reproducible using 'factor 122'.
This turns out to be somewhat related to http://bugs.gnu.org/12754,
but not quite the same. uintmax_t is 64 bits, but the cntlzw
instruction takes 32-bit operands, and the cntlzd option is only
available on 64-bit hardware.
