* src/df.c (filter_mount_list): Clarify why we still stat even
though devices IDs may already be available. Note using
/proc/self/mountinfo is still an advantage to get filtered items
with accurate device patchs in chroots and with bind mounts.
I.E. on older setups with static /etc/mtab, df will now
bypass that to get the more accuracte and dynamic info.
|
|
* src/chroot.c (main): Quote the passed argument,
to avoid confusing error messages.
|
|
* src/factor.c (print_uintmaxes): Comment that the
value of n_out doesn't matter on error, and add an
explicit cast to avoid any future warnings.
Suggested by Jim Meyering RE commit v8.23-229-g4d2d6c5

* src/make-prime-list.c (main): When building with
the above option, avoid this build stopping error:
"LeakSanitizer: detected memory leaks"
|
|
GCC 5.1.1 -fsanitize=undefined with glibc 2.21 is returning:
"runtime error: null pointer passed as argument 1,
which is declared to never be null"
* src/ptx.c (sort_found_occurs): Avoid the call with no entries.
|
|
* src/factor.c (n_out): A new global variable to track
how much data has been written to stdout.
(print_factors_single): Use n_out to determine whether
to flush the current (and previous) lines.
* tests/misc/factor-parallel.sh: Add a new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug fix.

src/seq.c (scan_arg): Set precision and width _after_ exponentiation.
For example, this will make '1.1e1 12' and '11 1.2e1' equivalent.
One can still set the precision by specifying extra precision on
the start value, or more naturally with a precision on a step value.
* tests/misc/seq-precision.sh: Add new cases.
|
|
* src/seq.c (scan_arg): Set precision to 0 for hex constants
(while avoiding hex floats). This will use then use the
fast path for these arguments. Note we also set the precision
of inf to 0 here, which ensures we use consistent precision
on output where possible.
* tests/misc/seq-precision.sh: Add corresponding test cases.
|
|
* src/seq.c (main): Call seq_fast for infinite last value.
This implicitly avoids format conversion on the
999999 -> 1000000 transition.
* src/seq.c (seq_fast): Generalize the buffer handling,
and adjust to handle the "inf" last value specifics.
* tests/misc/seq-precision.sh: A new test.
* tests/local.mk: Reference the new test.
|
|
* src/numfmt.c (MAX_UNSCALED_DIGITS): Set this to LDBL_DIG
rather than hardcoding at 18 for better portability.
* tests/misc/numfmt.pl: Restrict limit tests to supported platforms.
|
|
* src/numfmt.c (simple_strtod_int): Don't count leading zeros
as significant digits. Also have leading zeros as optional
for floating point numbers.
* tests/misc/numfmt.pl: Add test cases.
* NEWS: Mention the fix.
|
|
Due to existing limits this is usually triggered
with an increased precision. We also add further
restrictions to the output of increased precision numbers.
* src/numfmt.c (simple_round): Avoid intmax_t overflow.
(simple_strtod_int): Count digits consistently
for precision loss and overflow detection.
(prepare_padded_number): Include the precision
when excluding numbers to output, since the precision
determines the ultimate values used in the rounding scheme
in double_to_human().
* tests/misc/numfmt.pl: Add previously failing test cases.
* NEWS: Mention the fix.
|
|
* src/numfmt.c (usage): Update the --format description
to indicate precision is allowed.
(parse_format_string): Parse a precision specification
like the standard printf does.
(double_to_human): Honor the precision in --to mode.
* tests/misc/numfmt.pl: New tests.
* doc/coreutils.texi (numfmt invocation): Mention the new feature.
* NEWS: Likewise.
|
|
* src/numfmt.c: Replace field handling code with logic that understands
field range specifiers. Instead of processing a single field and
printing line prefix/suffix around it, process each field in the line
checking whether it has been included for conversion. If so convert and
print, otherwise just print the unaltered field.
(extract_fields): Removed.
(skip_fields): Removed.
(process_line): Gutted and heavily reworked.
(process_suffixed_number): FIELD is now passed as an arg instead of
using a global.
(parse_field_arg): New function that parses field range specifiers.
(next_field): New function that returns pointers to the next field in
a line.
(process_field): New function that wraps the field conversion logic
(include_field): New function that checks whether a field should be
converted
(compare_field): New function used for field value comparisons in a
gl_list.
(free_field): New function used for freeing field values in a gl_list.
Global variable FIELD removed.
New global variable all_fields indicates whether all fields should be
processed.
New global variable all_fields_after stores the first field of a N-
style range.
New global variable all_fields_before stores the last field of a -M
style range.
New global variable field_list stores explicitly specified fields to
process (N N,M or N-M style specifiers).
(usage): Document newly supported field range specifiers.
* bootstrap.conf: Include xlist and linked-list modules. numfmt now
uses the gl_linked_list implementation to store the field ranges.
* tests/misc/numfmt.pl: Add tests for 'cut style' field ranges.
Adjust existing tests as partial output can occur before an error
Remove test for the 'invalid' field -5.. this is now a valid range.
* gnulib: update to avoid compiler warnings in linked-list.
* NEWS: Mention the new feature.
|
|
* src/numfmt.c (usage): Don't scale output from df
so that numfmt outputs the correct values.
|
|
* src/numfmt.c (unit_to_umax): Support SI (power of 10) suffixes
with the --from-unit and --to-unit options. Treat suffixes like
is done with --from=auto, which for example will change the meaning
of --to-unit=G to that of --to-unit=Gi. The suffix support was
previously undocumented and it's better to avoid the traditional
coreutils suffix handling in numfmt by default.
* doc/coreutils.texi: Document the new behavior. Also fix a typo
mentioning {from,to}=units=.
* tests/misc/numfmt.pl: Adjust accordingly.
* NEWS: Mention the change in behavior.
|
|
* src/tail.c (recheck): Display diagnostices for replaced files
even with reused inodes which is a common case.
* tests/tail-2/F-vs-missing.sh: Use correct diagnostic in comment.
* tests/tail-2/F-vs-rename.sh: Likewise.
|
|
* src/tail.c (tail_forever_inotify): Use the fspec pointer to
distinguish previously output files, rather than a descriptor
from the inotify event. That event descriptor was that of
the parent directory when files were created or renamed etc.
(check_fspec): Adjust for the new comparison. Also show the
header when the file is truncated, since we show data
in this case also.
* tests/tail-2/F-headers.sh: A new test case.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug fix.

Problems reported by Michael Felt, and and part of this fix taken
from code suggested by Pádraig Brady in:
http://bugs.gnu.org/20733#112
* configure.ac (stdbuf_supported): Check for warnings, and
for -fPIC and -shared, for AIX.
* src/stat.c (STRUCT_STATVFS): Define to struct statvfs64 if
STATFS is statvfs64.
* src/sync.c (sync_arg) [_AIX]: Open in write mode,
since AIX fsync doesn't work on read-only file descriptors.
* tests/misc/wc-parallel.sh: Skip test if xargs -P does not work.
|
|
Problem reported privately by Michael Felt.
* Makefile.am (install-exec-hook):
* src/local.mk (src/coreutils_symlinks, src/coreutils_shebangs)
(clean-local):
Port to POSIX shell, which doesn't allow 'for i in ; do ...'.
|
|
* src/sync.c (sync_arg): Initialise variable to avoid
unitialized access if assert is disabled.
* src/head.c (elide_tail_bytes_file): Support this function
with ---presume-input-pipe and larger files,
which regressed with commit v8.23-47-g2662702.
(elide_tail_lines_file): Likewise.
* src/dd.c (dd_copy): Explicitly don't try to ftruncate()
upon failure to lseek() (the existing check against
st_size was already protecting that).
* src/factor.c (factor_using_squfof): Assert (only when
linting due to performance) to avoid the implication of
divide by zero.
* src/od.c (read_block): Remove dead code.
* src/tac.c (tac_seekable): Likewise.
* src/ls.c (gobble_file): Likewise.
|
|
* src/copy.c (CAN_HARDLINK_SYMLINKS): Don't enable use of linkat()
on Darwin 14, as the gnulib fallback emulation there doesn't
preserve ownership and timestamps etc. This fixes a test failure
in tests/cp/link-symlink.sh
* tests/cp/link-deref.sh: Adjust accordingly.
|
|
* src/system.h: This was inadvertently ineffective due to
a typo in commit v8.9-10-ge1aaf89 (Jan 2011), but has
not caused any issues, so remove.
|
|
When the parent directory exists and has a different
default context to the final directory, the context
was incorrectly left as that of the parent directory.
* src/mkdir.c (process_dir): Because defaultcon() is called for
existing ancestors (as it must be to avoid races), then we must
unconditionally call restorecon() on the last component due to
the already documented caveat with make_dir_parents().
Alternatively you could temp disable o->set_security_context
around make_dir_parents(), but that would be subject to races.
* tests (tests/mkdir/restorecon.sh): Add a TODO for improvement.
Reference mknod and mkfifo with print_ver_.
* NEWS: Mention the bug fix.
Fixes http://bugs.gnu.org/20616
|
|
* src/timeout.c (cleanup): Don't send SIGCONT to the monitored program
when --foreground is specified, as it's generally not needed for
foreground programs, and can cause intermittent signal delivery
issues with monitors like GDB for example.
* doc/coreutils.texi (timeout invocation): Mention that SIGCONT
is not sent with --foreground.
* NEWS: Mention the behavior change.
|
|
Supporting `split --numeric-suffixes=1 -n100` for example.
* doc/coreutils.texi (split invocation): Mention the two
use cases for the FROM parameter, and the consequences on
the suffix length determination.
* src/split.c (set_suffix_length): Use the --numeric-suffixes
FROM parameter in the suffix width calculation, when it's
less than the number of files specified in --number.
* tests/split/suffix-auto-length.sh: Add test cases.
Fixes http://bugs.gnu.org/20511
|
|
* src/wc.c (usage): State that it calculates display width.
* doc/coreutils.texi (wc invocation): Detail the distinct
items used to determine the display width.
|
|
Generally if logs are truncated, they're truncated to 0 length,
so output all existing data when our heuristic determines truncation.
Note with inotify, truncate() and write() are often determined
independently and so all data would be written if that was the case.
* src/tail.c (check_fspec): Reset file offset to 0 upon truncation.
(tail_forever): Likewise.
(recheck): Add a FIXME for the related issue where tail may lose
data due to tail discounting older log files too early.
* tests/tail-2/truncate.sh: A new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the fix.

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.

* src/system.h (is_ENOTSUP): Avoid in-function #if directive.
|

Without this change, very recent gcc (e.g., version 6.0.0 20150509)
would print the following when configured with --enable-gcc-warnings:
src/copy.c:165:30: error: logical 'or' of equal expressions \
[-Werror=logical-op]

* src/system.h (is_ENOTSUP): New function.
* src/copy.c (punch_hole): Use it.
* src/ls.c (errno_unsupported, gobble_file): Use it.
|
|
* src/system.h (emit_stdin_note): A new function, refactoring
the usage note about the '-' FILE implying stdin.
* src/base64.c (usage): Use the new function to emit the
note in a standard location and with standard separation.

the message referring to FILE1 or FILE2 as stdin.
* src/comm.c (usage): Add a message using the same
wording (translation) as used in join.
* src/split.c (usage): Reword to using FILE rather than
INPUT, allowing use of emit_stdin_note(). Also remove
the mention of "fixed-size" pieces as this isn't now
always the case.

* src/coreutils.c (usage): include coreutils.h outside
the printf call, because if it's a macro you will get the error:
embedding a #include directive within macro arguments is not supported
|
|
* src/yes.c (main): Simplify the logic so that the
compiler can see this function always returns a value.
This was seen with GCC 5.0 in SINGLE_BINARY mode.
|
|
With GCC 5 and the newly added warnings from gnulib, ensure the
correct signed integer is passed for the printf format,
to avoid -Werror=format= failures.
|
|
* src/local.mk (src_ls_LDADD): Change from LIB_ACL to LIB_HAS_ACL.
|
|
* src/longlong.h: Sync with the latest longlong.h from libgmp to:
- Use __builtin_c[lt]zl on arm64.
- Fix sparc64 vis3 build failure due to missing __clz_tab.
- Avoid a clang build issue on mips.
- Support thumb2 arm 32 bit system.
* src/cfg.mk (sc_ensure_comma_after_id_est): Exclude longlong.h
to ease merges.
|
|
All warnings were of the form: "assuming signed overflow does not occur
when simplifying conditional to constant [-Werror=strict-overflow]"
* src/dd.c (cache_round): Use an appropriately sized unsigned type,
to avoid possibility of undefined signed overflow.
* src/mknod.c (main): Likewise.
* src/pr.c (pad_down): Likewise.
* src/wc.c (main): Likewise.
* src/tail.c (main): Assert that argc >= 0 thus allowing the
compiler to assume without implication that argc - optind
is positive.
|
|
* src/dircolors.hin: Add the MISSING entry, to indicate
this as a possibility in new templates output from dircolors,
and also to ease comparison with existing databases that
generally do define a MISSING entry.
|
|
* src/df.c (filter_mount_list): With -l, avoid stating remote mounts.
* init.cfg: Avoid test hangs with inaccessible remote mounts.
* tests/df/no-mtab-status.sh: Skip with inaccessible remote mounts.
* tests/df/skip-rootfs.sh: Likewise.
* tests/df/total-verify.sh: Likewise.
* NEWS: Mention the bug fix.

* src/df.c (get_dev): Initialize the fsu.fsu_bavail_top_bit_set
member, when adding placeholder entries.
(main): Avoid a "definitely lost" memory leak warning from valgrind,
reported by Bernhard Voelker.
|
|
* src/ls.c (usage): Add punctuation to avoid ambiguity in the
description of the --time option. Mention that both the -u
and --sort=time default order is newest first.
|
|
* 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.

* src/ls.c (usage): Avoid the implication that the
default ls behavior is to --color=always.
Reported in http://bugs.debian.org/781208
|
|
* src/date.c (usage): Use FMT rather than TIMESPEC as the parameter,
since it's simpler to understand and can be better aligned.
Give an example for the --iso-8601 output format.
Adjust the example used for the 3 standard formats to be unambiguous
with respect to day/mon ordering and use of leading zeros in the time.
Reorder the options descriptions slightly, so that the
3 standards options are together.
Indent the multi-line descriptions so that grouping is obvious.
Remove a redundant description of the --rfc-3339 format,
which is obvious in the existing example.
Separate these 3 standards options to their own translatable string
to simplify translation.
Change 'date and time' to 'date/time' in the --iso-8601 description
to be consistent with --rfc-3339 and to help avoid the implication
that the time is always output or even output by default.

* src/uniq.c (usage): The description was very confusing in the man page
due to the stripped newlines. Add punctuation for clarification.
|
|
* src/wc.c (wc): Allow any block to select the count implementation,
rather than just using the first 10 lines. This also simplifies
the code from 3 loops to 2.

Using a test file generated with:
yes | head -n100M > 2x100M.txt
before> time wc -l 2x100M.txt
real 0.842s
user 0.810s
sys 0.033s
after> time wc -l 2x100M.txt
real 0.142s
user 0.111s
sys 0.031s
* src/wc.c (wc): Split the loop that deals with -l into 3.
The first is used at the start of the input to determine if
the average line length is < 15, and if so the second loop is
used to look for '\n' internally to wc. For longer lines,
memchr is used as before to take advantage of system specific
optimizations which any outweigh function call overhead.
Note the first 2 loops could be combined, though in testing,
GCC 4.9.2 at least, wasn't sophisticated enough to separate
the loops based on the "check_len" invariant.
Note also __builtin_memchr() isn't significant here as
GCC currently only applies constant folding with that.
* NEWS: Mention the improvement.
