* cfg.mk: Set XZ_OPT = -8e (determined empirically).
This sacrifices 8 KiB of compressed tarball size for a 32-MiB
decrease in the memory required during decompression. I.e.,
using -9e would shave off only 8 KiB from the tar.xz file, yet
would force every decompression process to use 32 MiB more memory.
* src/basename.c (perform_basename): New function refactored from
main() that performs the basename work on a STRING, optionally
removes a trailing SUFFIX and outputs the result.
(main): Handle new options.
* doc/coreutils.texi (basename invocation): Mention new options.
* test/misc/basename: Add new options test cases.
* NEWS (New features): Mention it.
Prompted by the continuous integration build failure at:
http://hydra.nixos.org/build/2188210 (which uses XFS).
* tests/dd/sparse (alloc_equal): Add a block allocation
comparison function that accounts for variations due
to alignment.
* src/timeout.c (usage): Document the exit status for this case,
in --help and thus in the man page. Word so that it covers
both the -s9 and -k options.
* doc/coreutils.texi (timeout invocation): Document the exit
status for this case.
* tests/ls/getxattr-speedup: Compile and link in one step with $CC.
If the shared object file is created by ld (binutils), then the
destructor print_call_count() may not run (seen on OpenSuSE 12.1).

Thanks to Cristian Rodríguez.
Notes:
Small seeks are not coalesced to larger ones,
like is done in cache_round() for example.
conv= is used rather then oflag= for FreeBSD compatibility.
* src/dd.c (final_op_was_seek): A new global boolean to flag
whether the final "write" was converted to a seek.
(usage): Describe the new conf=sparse option.
(iwrite): Convert a write of a NUL block to a seek if requested.
(do_copy): Initialize the output buffer to have a sentinel,
to allow for efficient testing for NUL output blocks.
If the last block in the file was converted to a seek,
then convert back to a write so the size is updated.
* NEWS: Mention the new feature.
* tests/dd/sparse: A new test for the feature.
* tests/Makefile.am: Reference the new test.
* src/sort.c (default_sort_size): Don't divide advice by 2.
Just divide the hard limits by 2. This matches the comments.

Add the --additional-suffix option, to append an
additional static suffix to output file names.
* src/split.c (next_file_name): Append suffix to output file names.
(main): Handle new --additional-suffix option.
* NEWS (New features): Mention it.
* doc/coreutils.texi (split invocation): Mention it.
* tests/split/additional-suffix: New file. Test --additional-suffix.
* tests/Makefile.am (TESTS): Add it.
Requested by Peng Yu, in bug 6554
* src/ls.c (errno_unsupported): Remove EBUSY, as this caters for
the case where ACLs can't be accessed because the _file_ is locked.
http://lists.gnu.org/archive/html/bug-coreutils/2005-06/msg00191.html
Also ENOENT is not safe to include as you get that if the _file_
is removed between the stat() and subsequent querying of xattrs.
Modern <stdio.h> provides ssize_t, but the one from Debian's
libc6-dev 2.11.2-10 apparently does not.
* tests/ls/getxattr-speedup: Also include <sys/types.h>.
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.
On systems or file systems without SELinux support, all getfilecon
and lgetfilecon calls would fail due to lack of support. We can non-
invasively cache such failure (on most recently accessed device) and
avoid the vast majority of the failing underlying getxattr syscalls.
* src/ls.c (errno_unsupported): New function.
(selinux_challenged_device): New file-scoped global.
(getfilecon_cache, lgetfilecon_cache): New error-caching wrapper
functions.
(gobble_file): Use the caching wrappers, for when many *getfilecon
calls would fail with ENOTSUP or EOPNOTSUPP.

Allow changing the --numeric-suffixes start number
from the default of 0.
* src/split.c (next_file_name): Initialize the suffix index
and the output filename according to start value.
(main): Check that the suffix length is large enough for the
numerical suffix start value.
* doc/coreutils.texi (split invocation): Mention it.
* NEWS (New features): Mention it.
* tests/split/numeric: New file. Test --numeric-suffixes[=FROM].
* tests/Makefile.am (TESTS): Reference the new test.
* doc/coreutils.texi (rm invocation): Mention that the -f option also
silences the message for missing operands, which is useful in scripts
e.g., for "rm -f $file_list" when $file_list is empty.
* src/rm.c (usage): Likewise.
Reported by Jérémy Magrin in http://bugs.gnu.org/10819
These edge cases were missed in the previous commit 140eca15c.
* src/dd.c (main): Include the bytes slop when truncating
without further I/O. Don't invalidate the whole file cache
in the case where 0 < count < ibs.
* tests/dd/bytes: Change to using the independent truncate
command to generate the file for comparison. Remove a redundant
test case and replace with one testing the truncation only logic.
dd now accepts the count_bytes and skip_bytes input flag and the
seek_bytes output flag, to more easily allow processing portions of a
file.
* src/dd.c (scanargs): Compute skip_records and skip_bytes when
'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.
(dd_copy): Skip accordingly to skip_records AND skip_bytes. Count
accordingly to max_records AND max_bytes. Seek on output accordingly
to seek_records AND seek_bytes.
* NEWS (New features): Mention it.
* doc/coreutils.texi (dd invocation): Detail new flags and behaviors.
* tests/dd/bytes: New file. Tests for these new flags.
* tests/Makefile.am (TESTS): Add it.
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.
* tests/mv/symlink-onto-hardlink-to-self: New test.
* tests/Makefile.am (TESTS): Add it.
* NEWS (Bug fixes): Mention it.

* src/pr.c (usage): Fix the -S description to indicate
that the argument is optional for the short option.
* doc/coreutils.texi (pr invocation): Likewise.
* src/od.c (usage): Fix the -S description to indicate
that the argument is required for the short option.
Clarify -w takes an argument and that it is optional.
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
tests makes mv refuse to perform a useful operation. Permit that
corner case.
* src/copy.c (same_file_ok): Detect/exempt this case.
* tests/mv/symlink-onto-hardlink: New test.
* tests/Makefile.am (TESTS): Add it.
* NEWS (Bug fixes): Mention it.

* cfg.mk (update-copyright-env): Add UPDATE_COPYRIGHT_FORCE=1
to rejoin some split lines, and UPDATE_COPYRIGHT_USE_INTERVALS=2
to make update-copyright use only one year range.
* gnulib: Update to latest, for newer update-copyright script.
* src/realpath.c (path_common_prefix): Be consistent and
always include a leading '/' in the count returned.
(relpath): Account for the change in path_common_prefix()
and avoid outputting extra '/' chars in relative paths that
span the root dir.
* tests/misc/realpath: Add the two reported cases.

Before init.sh and similar, we would set test=test_name, and then
construct temporary file names using $test. Now that each
init.sh-using test is in its own directory, that practice is unwelcome.
Remove bad examples.
* tests/rm/f-1: Per above.
* tests/rm/i-1: Likewise.
* tests/rm/interactive-always: Likewise.
* tests/rm/interactive-once: Likewise.
* tests/rm/ir-1: Likewise.
* tests/rm/r-1: Likewise.
* src/stat.c (usage): Indicate this is a transfer size
suggestion, rather than some persistent block size.
* doc/coreutils.texi (stat invocation): Likewise.
* doc/coreutils.texi (Opening the software toolbox): Remove commas
from @uref argument, so the alternate text renders properly in info.
Reported by Reuben Thomas.
The previous commit introduced a couple of spacing issues,
luckily one of which caused a test to fail.
* src/stat.c (default_format): Add a space so times are aligned.
* src/tr.c (string2_extentd): Remove an extraneous space.
Add a rule to ding any source file that has a continued string
with a word in the first column of the following line.
Those tend to trigger malfunction in tools that try to map an
arbitrary line number to an enclosing function name. Of course,
very many strings do precisely this, *when they are part of the
usage function*. So we exempt the body of each usage function.
* src/dircolors.c (main): Separate a long, continued string
into two separately-quoted parts.
* src/od.c (decode_one_format): Likewise.
(decode_one_format, main): Move a space from end of
preceding line to the beginning of the continued line.
* src/tr.c (unquote, string2_extend, validate): Likewise.
* src/seq.c (main): Split in two and use string concatenation.
* src/stat.c (default_format): Use a mix of techniques.
* cfg.mk (sc_prohibit_continued_string_alpha_in_column_1): New rule.
Exempt three files in src: system.h, od.c, printf.c.
The preceding commands ignored .[ch] files in lib/ and gl/.
This is what I should have been doing from the start:
git grep -l '`.*'\' $(g ls-files |grep '\.[ch]$') \
| xargs perl -pi -e 's/`(.+?'\'')/'\''$1/'
