Print warning regardless of locale, avoid warning if key is zero width.
Problem reported by Karl Berry in http://bugs.gnu.org/23665 .
* src/sort.c: (key_warnings): change conditions for 'leading spaces'
warning.
* tests/misc/sort-debug-warn.sh: adjust tests accordingly.
|
|
Easier troubleshooting of individual 'sort --debug' messages.
Discussed in http://bugs.gnu.org/23665 .
* tests/misc/sort-debug-warn.sh: add progress number before each sort
invocation.
|
|
* NEWS: Mention the bug fix.
* src/nl.c (proc_body, proc_footer): Reset numbering here too.
* doc/coreutils.texi (nl invocation): Adjust for behavior change.
* tests/misc/nl.sh: Add a test case.
|
|
* tests/df/skip-duplicates.sh: Skip the test when there is no
'/' entry listed by df, which was seen in certain chroot setups.

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.
(seq_fast, print_numbers): Explicitly check for write errors
and terminate the program with diagnostic.
* tests/misc/seq-io-errors.sh: Test error detection with /dev/full.
* tests/misc/seq-epipe.sh: Test error detection with broken pipes.
* tests/local.mk: Add new tests.
* NEWS: Mention the fix.
|
|
* src/yes.c (main): For large inputs only write a single
diagnostic for write errors.
* tests/misc/yes.sh: Test when /dev/full is available.
|
|
* src/sleep.c (main): Allow ERANGE since we allow "inf" values.
* src/timeout.c (parse_duration): Likewise.
* tests/misc/sleep.sh: New file. Tests for sleep(1).
* tests/misc/timeout-parameters.sh: Add case for newly allowed
$LDBL_MAX. Also use returns_ throughout the file. Also avoid
small timeout values which might give false failures under load.
|
|
* cfg.mk (sc_prohibit_expr_unsigned): expr uses intmax_t internally
when GMP is not available, so flag any uses of unsigned limits.
* tests/misc/timeout-parameters.sh: Remove the overflow related
to UINT_MAX as it's handled by the following case. Change the
following case from 99... to $TIME_T_OFLOW to be more expressive
in what it's actually testing. Directly check that commands succeed,
rather than inspecting $? afterwards.
* tests/dd/skip-seek-past-dev.sh: Guard against large device sizes.
* tests/id/setgid.sh: Protect: Guard against large group IDs.
* tests/misc/cut-huge-range.sh: Tweak comment to avoid syntax check.
It's tempting to simplify to just skip the test if expr fails,
but SIZE_MAX > INTMAX_MAX is the common case.
|
|
* tests/cp/parent-perm-race.sh: This new race introduced in
commit v8.25-5-g632eda5 is quite hard to hit, but is due to
`ls > fifo` doing write()/close()/exit() once `cp` has
open() the source fifo. Then the subsequent comparison of the
destination file may fail due to the file being missing or empty.
Previously `ls` generated output that was independent of `cp`.
Now we must wait for `cp` to finish before inspecting the
destination file that it wrote.
|
|
* tests/mkdir/p-v.sh: Set fail=1 when compare fails: the latter only
sets a non-Zero return code; evaluating that is up to the caller.
|
|
* src/seq.c (isnan): Define macro.
(scan_arg): Add check if the given argument is NaN, and exit with
a proper error diagnostic in such a case.
(usage): Document it.
* tests/misc/seq.pl: Add tests.
* doc/coreutils.texi (seq invocation): Document the change.
* NEWS (Changes in behavior): Mention the change.
|
|
* src/seq.c (main): Exit with an error diagnostic when the given
step value is Zero.
(usage): Document it.
* doc/coreutils.texi (seq invocation): Likewise.
* tests/misc/seq.pl: Add tests.
* NEWS (Changes in behavior): Mention the change.

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.
|
|
* tests/split/filter.sh: Use OFF_T_MAX-1 rather than OFF_T_MAX
as the size of a test file, to avoid false failure on an XFS file
system (or any file system permitting a file of size OFF_T_MAX).

sort, tail, and uniq now support traditional usage like 'sort +2'
and 'tail +10' on systems conforming to POSIX 1003.1-2008 and later.
* NEWS: Document this.
* doc/coreutils.texi (Standards conformance, tail invocation)
(sort invocation, uniq invocation, touch invocation):
Document new behavior, or behavior's dependence on POSIX 1003.1-2001.
* src/sort.c (struct keyfield.traditional_used):
Rename from obsolete_used, since implementations are now allowed
to support it. All uses changed.
(main): Allow traditional usage if _POSIX2_VERSION is 200809.
* src/tail.c (parse_obsolete_option): Distinguish between
traditional usage (which POSIX 2008 and later allows) and obsolete
(which it still does not).
* src/uniq.c (strict_posix2): New function.
(main): Allow traditional usage if _POSIX2_VERSION is 200809.
* tests/misc/tail.pl: Test for new behavior.
|
|
* src/split.c (lines_rr): Reinstate the conditional
setting of the WROTE boolean, as otherwise split -n r/1 would
consume all input when all --filter commands are stopped.
There was a test in place to check for this, but
it was incorrect as detailed below.
(input_file_size): Immediately disallow --number with
non seekable inputs, as such an invocation is not currently
generally supported and will fail as the data overflows
the internal buffer.
* tests/split/l-chunk.sh: Adjust to again disallow -n /dev/zero.
Also change all '&& fail=1' checks to use the 'returns_ 1' form.
* tests/split/filter.sh: Change the no longer supported /dev/zero
case to a regular $OFF_T_MAX file (supported on XFS for example).
Also fix the timeout(1) commands so they're not subject to
pipefail issues.
|
|
* tests/cp/parent-perm-race.sh: Add timeouts so that the test does
not wait forever on GNU/Hurd. This does not fix the underlying
bug but at least lets the tests make progress.
Problem reported by Nelson H.F. Beebe in: http://bugs.gnu.org/22624
Also, check that 'cp' actually copies the data; this is a better
test anyway, and simplifies the test code.
Also, avoid unlikely race if 'pid' is set in the environment.

Problem reported by Nelson H.F. Beebe in: http://bugs.gnu.org/22624
Other problems also fixed: basically, the code got confused because
GNU/Linux reports that /dev/zero has size zero.
* src/split.c (input_file_size): Now takes struct stat *, not just
size. Always store the first buffer. All callers changed. Treat
/dev/zero as an infinitely-large file, both on GNU/Linux where
fstat and lseek say its size is zero, and on GNU/Hurd where they
say the size is OFF_T_MAX.
(cwrite): Return true on success.
(bytes_split): Don't try to read past EOF, and stop if a write fails.
(lines_rr): Omit stray check for ignorable errno.
(main): Get file size only when n_units > 1, since that's the only
time it is needed. Defer most of the work to input_file_size.
* tests/split/l-chunk.sh: Adjust tests to match new behavior
on oddball inputs.
|
|
* tests/tail-2/wait.sh: Restrict inotify specific test portion
to local file systems and also not with ---disable-inotify specified.
Failure noticed on NFS.
|
|
* tests/rm/rm1.sh: Also remove the group write bit which
was required on one NFS setup at least. Note u-w was
enough to deny file creation, g-w was also required to
deny file removal.
* tests/rm/cycle.sh: Likewise.
* tests/mv/perm-1.sh: Likewise.
|
|
* tests/cp/preserve-slink-time.sh: Add a delay between the
ln and the cp so that there is enough difference between
the timestamps so GPFS won't discard the update.
Reported by Assaf Gordon.
|
|
* tests/misc/shred-passes.sh: Specify an exact amount to shred,
to avoid running out of simulated random data on file systems
with a large st_blksize like GPFS for example.
Reported by Assaf Gordon.
|
|
* tests/misc/head-c.sh: Further increase the limit to 8MB over
the base test command. 5.1MB was seen as minimum extra needed
on FreeBSD 9.3 x86_64.
|
|
* tests/rm/dangling-symlink.sh: The effective delay was only
1.5s. So delay before the operation, and increase the iteration
count by 1 to increase the delay to 6.3s. This failure was
noticed once on a FreeBSD 10.2 x86_64 virtual machine.
* tests/dd/stats.sh: Remove quotes on sleep argument
to ensure arguments are accumulated appropriately.
* tests/du/move-dir-while-traversing.sh: sleep before operation,
to increase the effective delay from 1.6s to 3.2s.
* tests/tail-2/flush-initial.sh: Likewise.
* tests/tail-2/pipe-f2.sh: Sleep first so that the effective delay
matches the commented value.
|
|
* tests/rm/r-root.sh: This test was seen to ERROR due to
sed input not having a terminating '\n'. Therefore just skip
with diagnostics upon failure to adjust the error output with sed.
Reported by Assaf Gordon.
|
|
* tests/install/create-leading.sh: Ensure $PWD is quoted.
Reported by `make dist-check`.
|
|
* init.cfg (dump_mount_list_): A new function to output the
system mount list.

* tests/df/skip-rootfs.sh: Likewise.
* tests/df/total-verify.sh: Likewise.
* tests/df/unreadable.sh: Likewise.
|
|
* tests/df/df-symlink.sh: Only check the symmetry of
the source <-> target lookup, when the source is only mounted once,
which isn't the case if '.' is a BTRFS subvolume for example.
Reported by Assaf Gordon on a default OpenSUSE 42.1 install.
|
|
* tests/misc/date.pl: This test was dependent on perl
unconditionally calling the system localtime() as date(1) does.
However perl has its own configure checks in place to avoid buggy
localtime implementations. Therefore comment out this test
as a FIXME for now. This test was seen to fail on FreeBSD 10
where localtime() returns nonsense values instead of failing
for arguments >= 2^56.
|
|
* tests/misc/head-c.sh: Further increase the limit, to account
for the fact that head(1) needs at least 1.576MB over the base test
command on FreeBSD 10. 4MB should be enough headroom while
still providing over allocation protection.
Reported by Assaf Gordon.
|
|
* src/operand2sig.c (operand2sig): Add a detailed comment explaining
why we validate even very large shell exit status values.
* tests/misc/kill.sh: Add a test case for the ksh scheme.
Simplify the INVALID signal number determination which also avoids
a false failure on systems like FreeBSD 10 with incomplete
signal list (caused by inaccurate NSIG).
|
|
* tests/cp/fiemap-extents.sh: Support RHEL6 fallocate
which doesn't support IEC suffixes like "MiB" on numbers.
Also add some extra framework_failure_ protections.
Reported by Assaf Gordon.

commit v8.23-31-g90aa291 failed to consider this case,
where the previous rename has failed, thus causing the
following to remove the specified directory:
mv dir dir dir
* src/copy.c (copy_internal): Assume this rename attempt has
succeeded, as a previous failure will already have been handled,
and we don't want to remove the source directory in this case.
* tests/cp/duplicate-sources.sh: Consolidate this test file to...
* tests/mv/dup-source.sh: ...here. Add test cases for same
source and dest.
* tests/local.mk: Remove the consolidated test.
* NEWS: Mention the bug fix.

At least the false positive in tail-2/follow-stdin.sh could be seen
on a 4-core i5 system with -j8. Fix similar cases. too.
* tests/tail-2/follow-stdin.sh: Empty the 'out' file in each iteration.
Otherwise, under heavy system load, 'check_tail_output' would see the
expected output from the previous round before tail would have the
chance to come up in the background.
While at it, move the creation of the 'exp' file out of the loop.

Instead of commit v8.24-132-g5171bef which only provides
control to disable this behavior (with -I), provide
the symmetrical "[-]drain" special setting.
* src/stty.c (main): Parse the [-]drain setting instead of -I,
and treat like a global option.
(usage): Adjust accordingly.
* tests/misc/stty.sh: Test "drain" with and without options.
* NEWS: Mention the new feature.
