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
for directories, but it is always 0 for a non-directory.
* tests/du/one-file-system: Add tests for this.
* NEWS (Bug fixes): Mention it.
Reported by Daniel Stavrovski in http://bugs.gnu.org/10967.
Introduced by commit v8.14-95-gcfe1040.

* 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.

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.
|

* 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).

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.

* tests/misc/help-version: Remove the $EXEEXT suffix from each
program name before comparing with a literal.

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.

Modern <stdio.h> provides ssize_t, but the one from Debian's

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.

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.

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/misc/realpath: Add the two reported cases.

Before init.sh and similar, we would set test=test_name, and then

Relax initial regexp to match more instances, but add a
filter to avoid some invalid conversions. Run this:
git grep -l "\`[^']*'" tests | xargs perl -pi -e '$q=q"'\''";' \
-e '$q="$q\\$q$q"; /(= ?\`|\`expr|\`echo|\Q$q\E)/ and next;' \
-e ' s/\`([^'\''"]*?'\'')/'\''$1/g'
The last disjunct in the above (...) filter is to exempt
any line that contains this string: '\''
With quoting like that, converting a ` to ' is likely to cause trouble,
so we'll handle those manually. Here are three examples where
the exemption is required:
*': `link-to-dir/'\'': hard link not allowed for directory'*) ;;
printf 'creating file `%s'\''\n' $f
'mv: inter-device move failed: `%s'\'' to `%s'\'';'\
|
|
Exempt lines with '$' or '=', since those are prone to improper
conversion. Run this:
git grep -l "\`[^']*'" tests \
|xargs perl -pi -e '/[=\$]/ and next;s/\`([^'\''"]*?'\'')/'\''$1/g'
|
|
Run this:
git grep -l "\\\\\`[^']*'" tests \
|xargs perl -pi -e 's/\\\`(.*?'\'')/'\''$1/g
|
|
Automatically adjust both the source (now in only one place)
and all tests that expect the resulting output via this:
git grep -l 'Try.*--help' src/system.h tests \
| xargs perl -pi -e 's/Try \\?`(\S+ --help)/Try '\''$1/'
|
|
* tests/misc/xstrtol: Use '...' to match new quoting in most places.
However, leave `9x' to match the sole comparison against output
from the quote function, which still uses `...'.
* tests/misc/sort-merge: Likewise, though here I had to leave
`...'-quoted output to match output from four tests.
* tests/pr/pr-tests: Convert a single `...' to '...'.
* gnulib: Update submodule to latest.

Commit 5eeaca94 added /sbin to the PATH for tests using mkfs. For other
tests, e.g. tests/cp-fiemap-perf using filefrag, we need /usr/sbin also.
Add both directories generally for the tests, "since many of us always
augment our PATH with all of the sbin paths all of the time anyway" (Bob
in http://lists.gnu.org/archive/html/coreutils/2011-11/msg00107.html).
The previous commit is hereby obsolete.
