This is used to discard terminal output on FreeBSD based systems.
* src/stty.c (mode_info): Add FLUSHO where supported.
(usage): Document for "local" and "combination" settings.
* doc/coreutils.texi (local stty settings): Document,
mentioning that this option is supported but ignored on GNU/Linux.
|
|
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.
|
|
In some cases an initial drain may block indefinitely as discussed at:
http://lists.gnu.org/archive/html/coreutils/2016-01/msg00007.html

* src/install.c (usage): Mention this commonly required functionality
in the -D option description.
* doc/coreutils.texi (install invocation): Likewise for the
--target-directory description.
|
|
* src/install.c (main): As an optimization, when calling
install_file_in_dir() for each file, only attempt to create
the target directory once, as this is invariant over the loop.
|
|
* src/install.c (mkancesdirs_safe_wd): Unconditionally
restore the current working directory when possibly called
multiple times (from install_file_in_dir()).

Problem noted by Pádraig Brady in: http://bugs.gnu.org/22277#8
Also, make the output a bit more precise while we're at it.
* NEWS: Document this.
* src/dd.c (previous_time): Remove, replacing with ...
(next_time): New var. All uses changed.
This avoids some rounding errors, and should be a bit faster.
(newline_pending): Remove, replacing with ...
(progress_len): New var. All uses changed.
This lets us keep track of how many trailing spaces to append.
(print_xfer_stats): Get the time first thing, so that it's
closer to being correct. Count the bytes output, and append
trailing spaces if needed. Add remarks to translators about
translation lengths.

* NEWS: Document this.
* doc/coreutils.texi (dd invocation): Use a simpler script.
Adjust output example to match new behavior.
* src/dd.c (human_size): Remove.
All uses changed to use human_readable and ...
(human_opts): ... this new constant.
(abbreviation_lacks_prefix): New function.
(print_xfer_stats): Use it. Output both --si and --human-readable
summaries, but only if they have prefixes.
* tests/dd/reblock.sh, tests/dd/stats.sh: Test new behavior.

We were erroneously skipping blanks in the marked comparison
_after_ the key start offset was applied.
* src/sort.c (debug_keys): Don't skip starting blanks
if already handled by begfield().
* tests/misc/sort-debug-keys.sh: Add a test case.
* NEWS: Mention the bug fix.

* src/stat.c (human_fstype): Add "overlayfs", and tag it as "remote"
to ensure that tail continues to use the more conservative polling mode.
* README-release: Remove a stale comment about updating fremote()
in tail.c. Also give a link to *_SUPER_MAGIC definitions
not in the standard linux/magic.h location.
* NEWS: Mention that this file system is recognized.

procps, bash >= 4.4, and util-linux >= 2.23
all have the -L option to output a table.

The character 'K' representing numeric user input can be confusing,
especially in the context where it can be suffixed by the multipliers
K, M, G, etc.
Use NUM instead.
* doc/coreutils.texi (head invocation): Replace @var{k} by @var{num}.
Also change @var{count} in the paragraph about the obsolete option
syntax.
(tail invocation): Likewise. Furthermore, adjust the option order to
alphabetical sorting.
* src/head.c (usage): s/K/NUM/ in as placeholder in the -c and -n
options. Furthermore, print the actual DEFAULT_NUMBER instead of the
hard-coded 10.
* src/tail.c (usage): s/K/NUM/ in as placeholder in the -c and -n
options. Add "[+]" to clarify that NUM may optionally be preceded by
this sign. Remove the redundant explanation of the optional '+' prefix
for NUM, as that is now clear from the option description above.
Suggested by Dan Jacobson in http://bugs.gnu.org/22042

|
* doc/coreutils.texi (uniq invocation): Fix the description of
problematic input to say "blank lines" rather than "two or more
blank lines".
(tr invocation): Clarify that -s only works with SET1 when
not translating (when SET2 not specified). Also explicitly
state in examples where blank lines are deleted.
Also add "deleting" to the menu item.
* src/tr.c (usage): Improve the -s summary to say it always
operates on the last specified SET.

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.
* tests/cp/fiemap-extents.sh: Renamed from tests/cp/fiemap-empty.sh
and re-enable parts checking the extents at and beyond EOF.
* tests/local.mk: Reference the renamed test.
* NEWS: Mention the bug fix.

* src/md5sum.c (digest_check): Update a matched_checksums bool upon
matched checksum, and fail (loudly unless --status is specified)
if there were no matches. Also change properly_formatted_lines
to a bool while at it since we don't need to track the plurality.
* tests/misc/md5sum.pl: Add a test case.
Suggested by Jim Meyering.
|
|
* doc/coreutils.texi (md5sum invocation): Document the new option.
* src/md5sum.c (digest_file): Return an empty digest to indicate
a missing file.
(digest_check): Don't fail or output status given an empty checksum.
(usage): Document the new option.
(main): Process and validate the new option.

* src/local.mk: Run `mkdir -p src` in all our explicit rules,
as in a VPATH build the src/ dir is only created at configure time
as a side effect of dependency tracking generation.
|
|
* src/c99-to-c89.diff: Remove file.
* src/local.mk (EXTRA_DIST): Remove it from this list.
* README (Pre-C99 build failure): Update section.

discussed in:
http://lists.gnu.org/archive/html/coreutils/2015-10/msg00091.html
* src/csplit.c: (save_line_to_file): check fwrite failures, report
and exit immediately instead of deferring to 'close_output'.
* tests/misc/csplit-io-err.sh: test fwrite failure using LD_PRELOAD.
* tests/local.mk: add new test.
|
|
* src/stat.c (human_fstype): Add new file system ID definitions.
* NEWS: Mention the improvement.
|
|
* src/paste.c (main): Use our styled wrapper for quotearg_colon().
* cfg.mk (sc_prohibit-quotearg): A new syntax check to avoid
future uses of unstyled quotearg to one of the internal slots,
and thus destined for diagnostic output.
|
|
* src/paste.c (main): Setting the quoting style to "escape"
went against the intent of the comment about presenting
doubled backslashes to the user. Instead use "c-maybe"
which is the only mode which avoids doubled backslashes,
and provides protection against arbitrary control characters.
* tests/misc/paste.pl: Adjust accordingly.
|
|
* src/ls.c (decode_switches): Set "shell-escape" if isatty().
* doc/coreutils.texi (ls invocation): Update the defaults description.
* NEWS: Mention the change in behavior. It should not have
backwards compat issues, but mentioning here just in case.
|
|
* src/printf.c (usage): Mention the new format.
(print_formatted): Handle the quoting by calling
out to the quotearg module with "shell-escape" mode.
* doc/coreutils.texi (printf invocation): Document %q.
* tests/misc/printf-quote.sh: New test.
* tests/local.mk: Reference new test.
* NEWS: Mention the new feature.

This is mainly noticeable when the multi-byte code
within ls.c is triggered by multi-byte quotes.
$ seq 200000 | xargs touch
$ time ls-old -U --quoting=locale --hide-control-chars >/dev/null
real 0m0.483s
$ time ls-new -U --quoting=locale --hide-control-chars >/dev/null
real 0m0.430s
* src/ls.c (quote_name): Avoid rescanning the output looking for
unprintable chars when we know the quoting mode already escapes them.
* tests/misc/ls-misc.pl: Add tests for all quoting modes, with and
without -q, to verify this assumption.
|
|
* doc/coreutils.texi (ls invocation): Describe the new
'shell-escape' and 'shell-escape-always' quoting options.
* src/ls.c (usage): Mention the new quoting options.
* tests/misc/ls-misc.pl: Add a test for 'shell-escape'
|
|
* src/test.c (test_syntax_error): Reuse verror() rather than
open coding the error output format.
(term): Don't hardcode '' quoting.
(main): Likewise.

Quote file names using the "shell-escape" or "shell-escape-always"
methods, which quote as appropriate for most shells,
and better support copy and paste of presented names.
The "always" variant is used when the file name is
embedded in an error message with surrounding spaces.
* cfg.mk (sc_error_shell_quotes): A new syntax check rule
to suggest quotef() where appropriate.
(sc_error_shell_always_quotes): Likewise for quoteaf().
* src/system.h (quotef): A new define to apply shell quoting
when needed. I.E. when shell character or ':' is present.
(quoteaf): Likewise, but always quote.
* src/*.c: Use quotef() and quoteaf() rather than quote()
where appropriate.
* tests/: Adjust accordingly.
|
|
* src/md5sum.c: Use the same file name escaping method used
when generating and checking checksums. I.E. ensure a single line
per file by starting the line with '\' for any file name containing '\n'
and replacing those with "\\n".
* NEWS: Move the item from changes in behavior to improvements,
since this is no longer a backwards incompat change when
processing stdout status messages.
* tests/misc/md5sum.pl: Remove quotes from expected status output.
* tests/misc/sha1sum.pl: Likewise.

Related to commit v8.24-61-g6796698 this provides
more consistent quoting, as quotearg_colon() defaults
to "literal" quoting by default, while quote()
provides appropriate quoting for diagnostics by default.
* gl/modules/randread: Depend on quote module rather than quotearg.
* gl/lib/randread.c: Used quote() not quotearg_colon().
* src/: Likewise.
* src/shred.c: Likewise. Also avoid unnecessary quoting
introducing overhead when wiping names.
* cfg.mk: Relax the matching expression to allow
"qname" variables as used in shred.c to satisfy the check.
* tests/: Adjust accordingly.
|
|
* src/date.c (main): Use %:z rather than %z with --iso-8601
as the standard states to consistently use extended format.
Note either format can be parsed by date.
* tests/misc/date.pl: Adjust accordingly.
* doc/coreutils.texi (du invocation): Clarify that "iso"
time styles are only similar to ISO-8601.
(ls invocation): Likewise.
(date invocation): Adjust the comment stating
that only --rfc-3339 output can be parsed by date(1).
* NEWS: Mention the change in behavior.
Reported at http://bugs.debian.org/799479

|
* src/factor.c: Move LIKELY() definition to...
* src/system.h: ...here.
(is_nul): Reimplement with a version that doesn't
require a sentinel after the buffer, and which calls
down to (the system optimized) memcmp.
Performance analyzed at http://rusty.ozlabs.org/?p=560
* src/dd.c (alloc_obuf): Simplify the is_nul() call by
not needing to write the sentinel.
* src/copy.c (sparse_copy): Likewise.
(copy_reg): Simplify the buffer allocation by avoiding
consideration of the sentinel in the buffer size calculation.
|
|
These strings are often file names or other user specified
parameters, which can give confusing errors in
the presence of unexpected characters for example.
* cfg.mk (sc_error_quotes): A new syntax check rule.
* src/*.c: Wrap error() string arguments with quote().
* tests/: Adjust accordingly.
* NEWS: Mention the improvement.
|
|
This is especially significant when using --check
with files generated on a windows system, where the \r
characters produce corrupted and confusing error messages.
This also ensures status messages are output on a single line.
* src/md5sum.c: Use quote() for printed file names.
* tests/misc/md5sum.pl: Adjust accordingly.
* NEWS: Mention the change in behavior.
