This provides better alignment when some names are quoted,
which also provides better indication that quotes are not
part of the name.
* src/ls.c (align_variable_outer_quotes): A new variable
set when ls is aligning columns (not using -m, non-zero -w),
and has a variable quoting style (shell, shell-escape, c-maybe).
(quote_name_buf): Writes to buffer rather than FILE,
taking care to avoid data copying if possible. Refactored from...
(quote_name): ...here. This now manages the buffer passed
to quote_name_buf() and outputs the padding, colors and name
in the appropriate order, while managing the --dired offsets.
(get_color_indicator): A new function to return the color sequence,
refactored from...
(print_color_indicator): ...here. This now simply outputs.
(print_dir): Refactor common parts to quote_name().
(clear_files): Reset the flag indicating at least one
file is quoted in the current directory.
(needs_quoting): A new function to indicate at the scan stage
whether a name needs quoting. Called from...
(gobble_file): ...here, until we find the first quoted file.
(print_name_with_quoting): Mostly refactored to quote_name().
* tests/ls/quote-align.sh: A new test for various output formats.
* tests/local.mk: Reference the new test.
* NEWS: Mention the improvement.

Note we don't support the --algorithm option of the
b2sum command in the external BLAKE2 project, as that
was deemed too confusing for users.
"BLAKE2b" was chosen as the default algorithm to use,

Ensure I/O errors are detected (and terminate seq), preventing seq
from infloop (or running for long time with a large
range) upon write errors or ignored SIGPIPE. Examples:
seq 1 inf > /dev/full (seq_fast)
seq 1.1 0.1 inf >/dev/full (print_numbers)
* src/seq.c (io_error): A new function to diagnose appropriate
stdio errors and exit the program with failure status.

The problematic code computed a struct tm in one time zone, and
then printed it or converted it to a string in another. To be
portable the same time zone needs to be used for both operations.
On GNU platforms this is not an issue, but incorrect output can be
generated on System V style platforms like AIX where time zone
abbreviations are available only in the 'tzname' global variable.
Problem reported by Assaf Gordon in: http://bugs.gnu.org/23035
* NEWS: Document the bug.
* src/date.c (show_date):
* src/ls.c (long_time_expected_width, print_long_format):
* src/pr.c (init_header):
* src/stat.c (human_time): Use localtime_rz instead of localtime,
so that the time zone information is consistent for both localtime
and time-formatting functions like fprintftime and nstrftime. For
'stat' this change is mostly just a code cleanup but it also
causes stat to also print nanoseconds when printing time stamps
that are out of localtime range, as this is more consistent with
what other programs do. For programs other than 'stat' this fixes
bugs with time zone formats that use %Z.
* src/du.c, src/pr.c (localtz): New static var.
(main): Initialize it.
* src/du.c (show_date): New time zone argument, so that localtime
and fprintftime use the same time zone information. All callers
changed.
* tests/misc/time-style.sh: New file.
* tests/local.mk (all_tests): Add it.
* tests/misc/date.pl: Test alphabetic time zone abbreviations.

fallocate can allocate extents beyond EOF via FALLOC_FL_KEEP_SIZE.
Where there is a gap (hole) between the extents, and EOF is within
that gap, the final hole wasn't reproduced, resulting in silent
data corruption in the copied file (size too small).
* src/copy.c (extent_copy): Ensure we don't process extents
beyond the apparent file size, since processing and allocating
those is not currently supported.

Since non interactive shells don't generally set $SHELL,
its value is propagated through the tests and may cause issues;
for example if $SHELL implicitly adjusts $PATH when run.
Instead we set $SHELL to that determined by the posix-shell module,
and use that consistently for all test sub scripts,
including those created thorugh the `split --filter` command.
* tests/local.mk: Explicitly set $SHELL to $(PREFERABLY_POSIX_SHELL)
which defaults to $CONFIG_SHELL and thus usually /bin/sh.
* tests/envvar-check: Remove bash environment variables with
side effects, in case /bin/bash was selected for $SHELL.

Generally if logs are truncated, they're truncated to 0 length,
so output all existing data when our heuristic determines truncation.

The previous fixes to races in the various tail tests,
identified actual races in the tail inotify implementation.
With --follow=descriptor, if the tailed file was replaced before
the inotify watch was added, then any subsequent changes were ignored.
Similarly in --follow=name mode, all changes to a new name were
effectively ignored if that name was created after the original open()
but before the inotify_add_watch().
* src/tail.c (tail_forever_inotify): Fix 3 cases.
1. With -f, don't stop tailing when file removed before watch.
2. With -f, watch right file when file replaced before watch.
3. With -F, inspect correct file when replaced before watch.
Existing tests identify these when tail compiled with TAIL_TEST_SLEEP.
* tests/tail-2/inotify-rotate-resources.sh:
This test also identifies the issue with --follow=name
when TAIL_TEST_SLEEP is used. Adjust so the test is immune
to such races, and also fail quicker on remote file systems.
* tests/tail-2/inotify-race2.sh: A new test using GDB,
based on inotify-race.sh, which tests the -F race
without needed recompilation with sleeps.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug.

* tests/tail-2/F-vs-missing.sh: Use standard "fastpoll" options
(-s.1 --max-unchanged-stats=1) to speedup the non-inotify case.
Add the non-inotify case to the test. `wait` on the background
tail process to terminate which should avoid the need for the
non standard `retry_delay_ cleanup ...` on NFS.
* tests/tail-2/F-vs-rename.sh: Remove 'out' at the start of the loop,
to avoid a race in checking its contents. Also ensure 'a' & 'b'
files are present before the tail process starts. Use the standard
"fastpoll" options as above.
* tests/tail-2/f-vs-rename.sh: Likewise.
* tests/tail-2/append-only.sh: Use more standard variable names.
* tests/tail-2/flush-initial.sh: Use "fastpoll" options for
non-inotify platforms. Also `wait` on the background tail to avoid
stray processes and file cleanup issues on NFS.
* tests/tail-2/inotify-hash-abuse.sh: Always run non-inotify case.
Use "fastpoll" options. Use a more standard retry_delay_ instead
of a hardcoded sleep loop. Add a `wait` on the background tail.
* tests/tail-2/inotify-hash-abuse2.sh: Likewise.
* tests/tail-2/inotify-rotate-resources.sh: Wait just on the
specific tail $pid needed.
* tests/tail-2/inotify-rotate.sh: Use "fastpoll" options.
* tests/tail-2/pid.sh: Use standard variable names.
Add a `wait` on the background tails.
* tests/tail-2/pipe-f2.sh: Likewise.
* tests/tail-2/tail-n0f.sh: Likewise.
* tests/tail-2/retry.sh: Use "fastpoll" options.
* tests/tail-2/symlink.sh: Likewise.
* tests/tail-2/wait.sh: Likewise. Speedup by using sub second
parameters to timeout(1). Improve the part ensuring that
-F never follows a renamed file.
* tests/tail-2/infloop-1.sh: Remove invalid test. tail(1) was not
being passed the --pid=$yes_pid option, retry_delay_ wasn't used
to avoid races, and yes could write huge files before being killed.
* tests/local.mk: Remove the invalid test reference.
* tests/tail-2/assert-2.sh: Rewrite using retry_delay_(). Since
no longer hardcoding large delays, remove the VERY_EXPENSIVE tag.
* tests/tail-2/assert.sh: Likewise.

* src/tail.c (tail_forever_inotify): Only monitor write()s and
truncate()s to files in --follow=descriptor mode, thus avoiding
the bug where we removed the watch on renamed files.
Also adjust the inotify event processing code that is
now significant only in --follow=name mode.
* tests/tail-2/F-vs-rename.sh: Improve this existing test by running
in both polling and inotify modes.
* tests/tail-2/f-vs-rename.sh: A new test based on the existing one.

yes(1) may be used to generate repeating patterns of text
for test inputs etc., so adjust to be more efficient.
Profiling the case where yes(1) is outputting small items
through stdio (which was the default case), shows the overhead
of continuously processing small items in main() and in stdio:
$ yes >/dev/null & perf top -p $!
31.02% yes [.] main
27.36% libc-2.20.so [.] _IO_file_xsputn@@GLIBC_2.2.5
14.51% libc-2.20.so [.] fputs_unlocked
13.50% libc-2.20.so [.] strlen
10.66% libc-2.20.so [.] __GI___mempcpy
1.98% yes [.] fputs_unlocked@plta
Sending more data per stdio call improves the situation,
but still, there is significant stdio overhead due to memory copies,
and the repeated string length checking:
$ yes "`echo {1..1000}`" >/dev/null & perf top -p $!
42.26% libc-2.20.so [.] __GI___mempcpy
17.38% libc-2.20.so [.] strlen

2.01% [kernel] [k] fsnotify
1.95% libc-2.20.so [.] _IO_file_write@@GLIBC_2.2.5
1.44% yes [.] main
We can avoid all stdio overhead by building up the buffer
_once_ and outputting that, and the profile below shows
the bottleneck moved to the kernel:
$ src/yes >/dev/null & perf top -p $!
15.42% [kernel] [k] __srcu_read_lock
12.98% [kernel] [k] __srcu_read_unlock

Note this change also ensures that yes(1) will only write

This patch fixes the handling of sub-bind-mount cycles which are
incorrectly detected as the file system errors. If you bind mount the
directory 'a' to its subdirectory 'a/b/c' and then run 'du a/b' you
will get the circular dependency warning even though nothing is wrong
with the file system. This happens because the first directory that is
traversed twice in this case is not a bind mount but a child of bind
mount. The solution is to traverse all the directories in the cycle
that fts detected and check whether they are not a (bind) mount.
* src/du.c (mount_point_in_fts_cycle): New function that checks whether
any of the directories in the cycle that fts detected is a mount point.
* src/du.c (process_file): Update the function to use the new function
that looks up all the directories in the fts cycle instead of only the
last one.
* tests/du/bind-mount-dir-cycle-v2.sh: New test case that exhibits the
described behavior.
* tests/local.mk: Reference the new root test.
* NEWS: Mention the bug fix.

* NEWS: Update the recent entry to also mention the avoidance
of incorrectly unlinking a multi-hardlinked "source" file when
presented with source and dest that only differ in case.
* src/copy.c (same_file_ok): Mention the case issue with same_name().
* tests/mv/hardlink-case.sh: Test the issue on HFS+.
* tests/local.mk: Reference the new test case.
* tests/mv/vfat: Remove an old related but unused test case.

We may run into a race condition if we treat hard links to the same file
as distinct files. If we do 'mv a b' and 'mv b a' in parallel, both a
and b can disappear from the file system. The reason is that in this
case the unlink on src is called and the system calls can end up being
run in the order where unlink(a) and unlink(b) are the last two system
calls. Therefore exit with an error code so that we avoid the potential
data loss.
* src/copy.c (same_file_ok): Don't set unlink_src that was used by mv,
and return false for two hardlinks to a file in move_mode.
*src/copy.c (copy_internal): No longer honor the unlink_src option,
used only by mv.
NEWS: Mention the change in behavior.
* tests/cp/same-file.sh: Augment to cover the `cp -a hlsl1 sl1` case.

Add the --enable-single-binary option to the configure file.
When enabled, this option builds a single binary file containing
the selected tools. Which tool gets executed depends on the value
of argv[0] which can be set implicitly through symlinks to the
single program.
This setup reduces significantly the size of a complete coreutils
install, since code from lib/libcoreutils.a is not duplicated in
every one of the more than 100 binaries. Runtime overhead is
increased due to more dynamic libraries being loaded, and extra
initialization being performed for all utils. Also initially
a larger binary is loaded from storage, though this is usually
alleviated due to caching and lazy mmaping of unused blocks,
and in fact the single binary should have better caching
characteristics.
Comparing the size of the individual versus single binary on x86_64:
$ cd src
$ size coreutils
$ size -t $(../build-aux/gen-lists-of-programs.sh --list-progs |
grep -Ev '(coreutils|libstdbuf)') | tail -n1
text data bss dec hex filename
1097416 5388 88432 1191236 122d44 src/coreutils
4901010 124964 163768 5189742 4f306e (TOTALS)
Storage requirements are reduced similarly:
$ cd src
$ du -h coreutils
$ du -ch $(../build-aux/gen-lists-of-programs.sh --list-progs |
grep -Ev '(coreutils|libstdbuf)') | tail -n1
1.2M coreutils
5.3M total
When installing, the makefile will create either symlinks or
shebangs based on the --enable-single-binary setting, for
each configured tool. In this way, all the tools are still
callable individually, but they are all implemented by the same
"coreutils" binary installed on the same directory.
