A side effect of this cleanup is we no longer
depend on our own kill command being built.
* init.cfg (require_trap_signame_): A new function to verify
that the shell supports specifying traps by signal name.
(require_kill_group_): A new function to ensure the shell
supports sending a signal to a group.
* tests/du/move-dir-while-traversing.sh: Ensure trap supports
signal names.
* tests/misc/stty-invalid.sh: Likewise.
* tests/misc/stty-pairs.sh: Likewise.
* tests/misc/stty-row-col.sh: Likewise.
* tests/misc/stty.sh: Likewise.
* tests/misc/sort-compress.sh: Likewise. Also simplify trap call.
* tests/install/trap.sh: Likewise.
* tests/misc/timeout.sh: Likewise.
* tests/dd/stats.sh: Likewise. Also use default kill command.
* tests/misc/timeout-group.sh: Likewise.

|
* init.cfg (require_dirent_d_type_): Don't use df -x
to exclude XFS, since this depends on a correct mtab
which is brittle and often not correct within chroots.
* tests/d_type-check: Check also the d_type of files,
which excludes XFS appropriately. Specify all argument
and return types to avoid truncated pointers being passed,
which skipped the test due to crashes on x86_64 at least.
Simplify the C library lookup by reusing the interpreter's.

* 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.
|
|
Includes support for "shell-escape" from quotearg
|
|
* 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.
|
|
* doc/coreutils.texi: (tail invocation): Add missing -s,
along with the existing --sleep-interval description.
(csplit invocation): s/--suffix/--suffix-format/.
(head invocation): Use same variable (COUNT) for -n and --head-count.
(seq invocation): Add opindex items for all options.
(ptx invocation): Likewise.
Fix typo s/--flac-truncation/--flag-truncation/.
(touch invocation): State explicitly that -d takes a parameter,
which also indicates that an '=' is not to be used
for the short option syntax.
(ls invocation): Likewise for the -w option.

and affect all (or many) commands.

|
* doc/coreutils.texi (du invocation): Remove 'like' from
mentions of ISO-8601 as the components are individually conformant.
(ls invocation): Likewise, except for --time-style=iso for recent
files, where the MM-DD component is not a valid ISO-8601 timestamp.
|
|
* 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.

* 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.

* src/ls.c (main): Account for the first column not including
a separator when calculating max_idx.
* tests/ls/w-option.sh: Add a test case.
* NEWS: Mention the bug fix.
|
|
* src/ls.c (print_with_separator): Renamed from print_with_commas,
and parameterized to accept the separator to print.
Also fix an edge case where '\n' not printed when
the POS variable overflows SIZE_MAX.
(print_current_files): Degenerate -x and -C to using the
cheaper print_with_separator() in the -w0 case.
* doc/coreutils.texi (ls invocation): Document the new feature.
* tests/ls/w-option.sh: A new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the improvement.

* src/ls.c (know_term_type): Corresponding to commit v8.24-48-gc249a5a,
use fnmatch to inspect the dircolors database. Noticed due to
failing tests/ls/color-{dtype-dir,term}.sh tests.
|
|
* tests/misc/csplit-heap.sh: A little more memory is required
for the full run case. Noticed with --enable-single-binary.

The gnulib provided sc_tight_scope target was ineffective,
as it was checking against an invalid blank regular expression,
and thus ignoring any extern function issues. This is now
fixed up in gnulib, and so we need to fix our scoping issues
before the next gnulib update.
* cfg.mk: Setup and document the tight_scope config variables
appropriately.
* src/selinux.h: Since declared in *_SOURCES, use the two line
form for the extern function declarations.
* src/set-fields.h: Add the extern declarations, and since declared
in noinst_HEADERS use the single line form.
|
|
* tests/factor/run.sh: If this template is found through
`grep -El "print_ver_.* factor"` for example, then just skip it.

It was a little confusing as to whether the SQUFOF algorithm was
enabled, and in fact there were no options available to enable it.
Therefore clarify the 3 configurable behaviors for the code to
3 defines at the top of the program, and only include the SQUFOF
code if enabled at compile time.
$ size src/factor-before
text data bss
93997 1412 2504
$ size src/factor-after
text data bss
87885 1404 2504
* src/factor.c: Only include the SQUFOF factor code
when enabled via the USE_SQUFOF define.
* doc/coreutils.texi (factor invocation): Update note about
factor limits, as we can factor 128 bit numbers without GMP.
|
|
* man/sort.x: Cross reference with shuf(1).
* src/sort.c (usage): Mention shuf(1) with -R option.
Suggested in http://bugs.debian.org/641166
|
|
* tests/local.mk (all_tests): Remove the tests 'tests/id/setgid.sh' and
'tests/mkdir/smack-root.sh' because they are mentioned in the
'all_root_tests' list; these tests are skipped anyway during a non-root
run because flagged with 'require_root_'.

sha512sum can be faster than sha256sum.
E.g., ‘dd if=/dev/zero bs=1024k count=1024 | time sha256sum’
reports 8.16 user CPU seconds on my host, whereas sha512sum
consumes 5.45 seconds (Fedora x86-64 on an AMD Phenom II X4 910e).
Although sha512sum is still considerably slower on x86, a good
chunk of uses are on 64-bit hosts and anyway there’s little point
to scaring people away from sha512sum nowadays.
* doc/coreutils.texi (sha2 utilities): Remove obsolete comment.

|
* src/uniq.c (main): Make the type of "nfiles" unsigned,
to avoid a brand new warning from a gcc I built from today's
sources (gcc version 6.0.0 20151015 (experimental) (GCC)):
src/uniq.c:523:14: error: assuming signed overflow does not occur \
when simplifying conditional to constant [-Werror=strict-overflow]

* src/dircolors.c (dc_parse_stream): Support globbing of
TERM entries, to allow entries like "TERM *256color*" for example.
* src/dircolors.hin: Reduce the internal list with globbing.
* tests/misc/dircolors.pl: New test cases.
* NEWS: Mention the improvement.
|
|
* tests/rm/r-root.sh: Skip the test if there are gdb warnings
that will impact further stderr checks. For example some
buggy gdb versions may report "Got object file from memory
but can't read symbols: File truncated". Also fix an incorrect
stderr check from the previous change.
Reported by Bernhard Voelker.
|
|
* tests/rm/r-root.sh: Use gdb rather than timeout(1) as the
last resort protection against unlinkat() calls. The timeout
of 2s was susceptible to false positives under load, and
gdb is stronger protection in any case. We remove the
"expensive" tag on this test also since it should be robust.
Reported by Jim Meyering.
|
|
* tests/tail-2/follow-stdin.sh: Use the standard tail
testing framework to avoid the race seen under very high load,
and also test the non inotify case.

* init.cfg (require_no_default_acl_): A new function to skip
when default ACLs are detected, or if the getfacl utility is
not available then skip if any non LSM ACLs detected.
* tests/cp/existing-perm-race.sh: Call require_no_default_acl_.
* tests/mkdir/parents.sh: Likewise.
* tests/mkdir/perm.sh: Likewise.
|
|
* src/tail.c (fremote): No longer prompt the user to email
with the unrecognized file system constant, since we have
process in place to sync periodically with the latest Linux
constants, and the fall back polling mode is still fully functional.
|
|
* tests/cp/cp-a-selinux.sh: Ensure we skip the portion of the test
depending on restorecon to be effective. I.E. also skip when restorecon
warns, as it doesn't exit with error status when matchpathcon fails to
find a match for a file. This is the case in /tmp on Fedora for
example, in which case the new destination that cp creates will have the
default security context of the process, rather than the explicit
context we set on the source file.
Details at: http://bugzilla.redhat.com/1247641
|
|
* tests/misc/sort-compress-hang.sh: Use --foreground with the
timeout(1) command (noting the caveats), to run the sort command
in the foreground program group, and thus be responsive to Ctrl-C.
This very_expensive_ test takes over a minute on a i3-2310M,
with RAM backed /tmp.
|
|
* tests/dd/no-allocate.sh: Account for timeout(1) when
determining the required mem, as timeout has additional shared libs.
This avoids the need for the hardcoded 4M addition to the limit.
* tests/misc/head-c.sh: Increase the base limit, to account for
the fact that head(1) will allocate some additional mem in this case.
* tests/misc/cut-huge-range.sh: Remove mention of specific limits.
* tests/misc/printf-surprise.sh: Likewise.

* src/tee.c (tee_files): Last arg is now char ** instead of char
const **, as that is a bit simpler. All callers changed. Modify
files[-1], not files[nfiles], as that is a bit faster and simpler.

This pacifies GCC 5 in a better way, without disabling diagnostics.
* src/df.c (main): Tell compiler that optind is positive.
* src/shred.c (known): New function.
(dopass): Go back to off_t for file sizes.
Avoid integer overflow if we run off the end of the file.
Tell compiler that a write cannot write more bytes than requested.
|
|
Avoid the intermittent loss of "... has become inaccessible" messages.
That would cause tests/tail-2/assert.sh to fail sometimes,
mainly on uniprocessor systems.
* src/tail.c (tail_forever_inotify): Also monitor IN_DELETE
events on the directory, to avoid a dentry unlink()..open() race,
where the open() on the deleted file was seen to succeed after an,
unlink() and a subsequent IN_ATTRIB, was sent to tail. Note an
IN_ATTRIB is sent on the monitored file to indicate the change in
number of links, and we can't just use a decrease in the number of
links to determine the file being unlinked, due to the possibility
of the file having multiple links.
Reported by Assaf Gordon and Ludovic Courtès.

* src/shred.c (dopass): With -O2, GCC 5.1 gives "assuming signed
overflow does not occur when simplifying conditional to constant"
warnings, in regard to the signed (off_t) variables. Therefore
use unsigned (uintmax_t) instead, and a separate boolean to cater
for the special meaning of the negative part of the integer range.
Noticed at http://hydra.nixos.org/build/24983447

|
Includes a change to xalloc.h to avoid -Wstrict-overflow warnings
with GCC 5.1 on 32 bit with optimization enabled. A subsequent
commit will fix similar issues in shred.
|
|
* src/dircolors.hin: Add "xterm-termite" as this VTE based terminal
emulator is quite different from xterm, despite the name.
For example "Termite supports italic text and it won't work if TERM
is set to xterm. Even the backspace key won't work properly anymore
for applications relying on terminfo".

In the presence of bind mounts of a device, the 4th "mount root" field
from /proc/self/mountinfo is now considered, so as to prefer mount
points closer to the root of the device. Note on older systems with
an /etc/mtab file, the source device was listed as the originating
directory, and so this was not an issue.
Details at http://pad.lv/1432871
* src/df.c (filter_mount_list): When deduplicating mount entries,
only prefer sources nearer or at the root of the device, when the
target is nearer the root of the device.
* NEWS: Mention the change in behavior.
