https://lists.gnu.org/archive/html/bug-gnulib/2012-02/msg00038.html
detailed a couple of bugs in gnulib's canonicalize that were visible
through coreutils' readlink, but only on systems where // is distinct
from /. This particular test assumes the POSIX fix which requires
canonicalization of a symlink containing just slashes to behave as
if slashes separating the symlink from the rest of the name are
elided (see http://austingroupbugs.net/view.php?id=541), as that is
the only useful (and current) behavior on Cygwin. That is,
ln -s / root
ls root/dev
must list the contents of /dev, not //dev.
* tests/misc/readlink-root: New test.
* tests/Makefile.am (TESTS): Run it.
* tests/Makefile.am (TESTS): Add misc/sort-discrim.
* tests/misc/sort-discrim: New file, which tests a discriminator-based
implementation of 'sort'. Coreutils doesn't use this implementation
yet, but the test is useful anyway.

* src/dirname.c (main): Handle new -z option and manage more than one
argument.
* doc/coreutils.texi (dirname invocation): Mention it.
* NEWS (New features): Mention it.
* tests/misc/dirname: Add a two arguments test.
* src/split.c (next_file_name): If `suffix_auto' is true and the first
suffix character is 'z', generate a new file file name adding `z' to
the prefix and increasing the suffix length by one.
(set_suffix_length): Disable auto suffix width in various cases.
* tests/split/suffix-auto-length: Test it.
* doc/coreutils.texi (split invocation): Mention it.
* NEWS (Improvements): Likewise.
* NEWS: Document this.
* doc/perm.texi (Operator Numeric Modes): New section.
(Numeric Modes, Directory Setuid and Setgid): Document new behavior.
* src/chmod.c (usage): Document new behavior.
(main): Support new options -0, -1, etc.
* tests/chmod/setgid: Test these new features.
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.
(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.
* 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.
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
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>.
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.
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.
Reported by Bernhard Voelker in http://bugs.gnu.org/10686
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.
Initially reported by: Matt McCutchen in http://bugs.gnu.org/6960.
Raised again by Anders Kaseorg due to http://bugs.debian.org/654596.
Improved-by: Paul Eggert.
* 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.
Reported by Mike Frysinger
Before init.sh and similar, we would set test=test_name, and then
construct temporary file names using $test. Now that each
init.sh-using test is in its own directory, that practice is unwelcome.
Remove bad examples.
* tests/rm/f-1: Per above.
* tests/rm/i-1: Likewise.
* tests/rm/interactive-always: Likewise.
* tests/rm/interactive-once: Likewise.
* tests/rm/ir-1: Likewise.
* tests/rm/r-1: Likewise.
Relax initial regexp to match more instances, but add a
filter to avoid some invalid conversions. Run this:
git grep -l "\`[^']*'" tests | xargs perl -pi -e '$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'
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.
* tests/misc/timeout-parameters: Verify that the timer doesn't
fire immediately in the problematic range, and avoid overflow
checks in that case.
* man/timeout.x: Mention the possible bug.
Reported by Bruno Haible
* cfg.mk (sc_prohibit_short_facl_mode_spec): New rule.
* tests/cp/acl: Extend setfacl mode spec to have length 3.
* tests/ls/slink-acl: Likewise.
* tests/mv/acl: Likewise.
Report and analysis by Bruno Haible.
* src/split.c (lines_chunk_split): Fix logic bug that led to
unwarranted failure of "split -n l/2 /dev/zero" on NetBSD 5.1.
The same would happen when splitting a growing file, where
open/lseek-end gives one size, but by the time we read, there
is more data available.
(bytes_chunk_extract): Likewise.
* NEWS (Bug fixes): Mention this.
* tests/split/l-chunk: The latter case was not exercised.
Add code to do that.
Bug introduced with the chunk-selecting feature in v8.7-25-gbe10739.

This program is compatible with other realpath(1)
implementations, and also incorporates relpath like support,
through the --relative options. The relpath support
was suggested by Peng Yu, who also provided an initial
implemenation of that functionality.
* AUTHORS: Add my name.
* NEWS: Mention the new command.
* README: Likewise.
* doc/coreutils.texi (realpath invocation): Add realpath info.
* man/Makefile.am (realpath.1): Add dependency.
* man/realpath.x: New template.
* man/.gitignore: Ignore generated man page.
* po/POTFILES.in: Add src/realpath.c.
* src/.gitignore: Exclude realpath.
* src/Makefile.am (EXTRA_PROGRAMS): Add realpath.
* src/realpath.c: New file.
* scripts/git-hooks/commit-msg: Add realpath to the list of prefixes.
* tests/Makefile.am (TESTS): Add misc/realpath.
* tests/misc/realpath: New file.
* tests/check.mk (.built-programs): Depend on src/Makefile.am,
so that when we add a program, this file is updated, and the new
program is tested via misc/help-version. Spotted by Pádraig Brady.
This fixes Bug#10293, which I guess was introduced in commit
95c948b06a dated 2003-10-02.
* NEWS: Document fix.
* src/du.c (process_file): Don't count files in different file
systems if -x is given.
* tests/du/one-file-system: Test for this bug.
* src/ls.c (decode_switches): Replace our use of XARGMATCH
with open-coded version so that we can give a better diagnostic.
* tests/ls/time-style-diag: New file.
* tests/Makefile.am (TESTS): Add it.
Reported by Dan Jacobson in http://bugs.gnu.org/10253
with suggestions from Eric Blake and Paul Eggert.
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.
* tests/init.cfg (sanitize_path_): Add /sbin and /usr/sbin to PATH
unless already included. Needed for tests using admin tools like mkfs
and filefrag on systems where the user's environment does not have
these directories in the PATH.
* tests/init.cfg (require_mkfs_PATH_): Remove obsolete function.
* tests/cp/cp-a-selinux: Remove require_mkfs_PATH_ call.
* tests/cp/cp-mv-enotsup-xattr: Likewise.
* tests/cp/sparse-fiemap: Likewise.
* tests/mkdir/writable-under-readonly: Likewise.
* tests/rm/read-only: Likewise.
Commit 5b3e538 proved useful enough to migrate to gnulib after
enhancing it to be more generic, which in turn pointed out that
commit a2c811db missed an offender.
* gnulib: Update to latest.
* cfg.mk (sc_prohibit_reversed_compare_failure): Delete, now that
gnulib provides it.
* tests/ls/dangle: Fix last offender.
