* 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/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.

* 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/misc/wc-files0.sh: $fail is always set to 0,
so correct the test to include that part of the test case.
|
|
* src/wc.c (write_counts): Shell escape the file name
if it contains '\n' so only a single line per file is output.

|
|
* src/comm.c (main): Track the output delimiter length,
so that it can be adjusted to 1 for the NUL delimiter.
Also rename the global variable from "delimiter" to
"col_sep" so its use is more obvious, and to distinguish
from the recently added "delim" global variable.
* tests/misc/comm.pl: Adjust accordingly.

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.
* tests/dd/stats.sh: Empty the output file of the background process
here, too.
* tests/misc/cat-buf.sh: Likewise.
* tests/misc/stdbuf.sh: Likewise.

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/stty.c (main): Use TCSANOW rather than TCSADRAIN if -I specified.
(usage): Document the new option.
* doc/coreutils.texi (stty invocation): Likewise.
* tests/misc/stty.sh: Ensure -I is supported.
* NEWS: Mention the new feature.

* init.cfg (get_min_ulimit_v_): Increase the determined
virtual memory limit for the command by a page size
to avoid alignment issues causing false failures for
subsequent runs.
* tests/misc/cut-huge-range.sh: Be defensive and match
the cut invocations under test, more closely with the
form used to determine the VM memory limit.

We were erroneously skipping blanks in the marked comparison
_after_ the key start offset was applied.

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.

A side effect of this cleanup is we no longer
depend on our own kill command being built.

* 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.

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'

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.

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.

TERM entries, to allow entries like "TERM *256color*" for example.

* 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.

When configured with either 'symlinks' or 'shebangs' as value for
the --enable-single-binary option, tests based on `ulimit -v` are
skipped. The reason is that the multicall 'coreutils' binary requires
much more memory due to shared libraries being loaded, and the size of
the 'date' binary (~290KiB) compared to the multicall binary (~5MiB),
of course. Finally, in the case of 'shebangs', the starting shell
requires more memory, too
Instead of using hard-coded values for the memory limit, use an
adaptive approach: first determine the amount of memory for a similar,
yet more trivial invocation of the command, and then do the real test
run using that limit (plus some buffer in some cases).
* init.cfg (require_ulimit_v_): Remove function.
(get_min_ulimit_v_): Add function to determine the minimum memory limit
required for a given command in an adaptive way.
* cfg.mk (sc_prohibit_test_ulimit_without_require_): Change the name
of the above function in the syntax-check rule.
* tests/cp/link-heap.sh: Use the above function to determine the
minimum memory required to run a command simpler than in the real test
run. Use that limit plus a buffer there. While at it, change to list
of commands in the subshell to fail also if the beginning `ulimit -v`
fails.
