* src/dd.c (dd_copy): Give a better diagnostic than
"dd: memory exhausted" for an over-large bs= block size setting.
Same for ibs= and obs=. Reported by Imre Péntek in
http://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/591969
|
|
* src/ls.c (gobble_file): Revert part of my preceding change,
to avoid clobbering stack.
|
|
* src/tail.c (xlseek): Give INT_BUFSIZE_BOUND a variable name,
not a type name.
* src/ls.c (gobble_file, format_user_or_group_width): Likewise.
* src/head.c (elide_tail_bytes_pipe): Likewise.
(elide_tail_lines_seekable, main): Likewise.
[This change is not complete -- there are doubtless other uses
that can be updated in the same way.]
|
|
sprintf is relatively heavy-weight.
* src/sort.c (key_warnings): Use umaxtostr and stpcpy rather
than sprintf.
Also, replace each INT_BUFSIZE_BOUND "type_name" argument
with the equivalent variable name. More maintainable that way.
|
|
* doc/coreutils.texi (dirname invocation): Reword to be more
precise.
* src/dirname.c (usage): Likewise.
* THANKS: Update.
Reported by Filipus Klutiero, bug 6175.

* src/touch.c (main): Remove support for the deprecated, long-named
--file option, which is an alternate name for --reference (-r).
That option was undocumented with the arrival of --reference, in
the 1995-10-29 commit, 8b92864e1d. Since the 2009-02-09 commit,
ed85df444a, use of --file has elicited a warning. Not only was
this code due for removal, but the long-name-use-detecting code
was buggy in that it would use a stale or uninitialized "long_idx",
as reported by Robin H. Johnson in http://bugs.gentoo.org/322421.
* NEWS (Changes in behavior): Mention it.

E.g.,
- size_t desired_width IF_LINT (= 0);
+ size_t desired_width IF_LINT ( = 0);
Use this command:
g grep -l IF_LINT | grep '\.[ch]$' \
| xargs perl -pi -e 's/(IF_LINT \()= /$1 = /'
|
|
Run this command:
git ls-files | grep '\.[ch]$' \
| xargs perl -pi -e 's/for \(;;\)/while (true)/g'
...except for randint.c, which does not include stdbool.h.
In that case, use "while (1)".

Instead, include "alignof.h", and sort the #include directives.
And get its definition from the gnulib module by that name:
* bootstrap.conf (gnulib_modules): Add alignof.

Previously we copied `dd` and suppressed error messages
when truncating neither regular files or shared mem objects.
This was valid for `dd`, as truncation is ancillary to copying
it may also do, but for `truncate` we should display all errors.
Also we used the st_size from non regular files which is undefined,
so we display an error when the user tries this.
* src/truncate (do_truncate): Error when referencing the size
of non regular files or non shared memory objects. Display all
errors returned by ftruncate().
(main): Error when referencing the size of non regular files or
non shared memory objects. Don't suppress error messages for
any file types that can't be opened for writing.
* tests/misc/truncate-dir-fail: Check that referencing the
size of a directory is not supported.
* tests/misc/truncate-fifo: Ensure the test doesn't hang
by using the `timeout` command. Don't test the return from
running ftruncate on the fifo as it's system dependent as
to whether this fails or not.
NEWS: Mention the change in behavior.

* doc/coreutils.texi (truncate invocation): Mention that --reference
bases the --size rather than just setting it.
* src/truncate.c (usage): Likewise. Also remove the clause
describing --size and --reference as being mutually exclusive.
(do_truncate): Add an extra parameter to hold the size
of a referenced file, and use it if positive.
(main): Pass the size of a referenced file to do_truncate().
* tests/misc/truncate-parameters: Adjust for the new combinations.
* NEWS: Mention the change

* src/shuf.c (main): Remove a stray newline in a diagnostic.
* src/od.c (main): Likewise.
Detected via these:
git grep -A1 'error *(.*,$' | grep -C1 '\\n"[,)]'
git grep 'error *(.*;$' | grep '\\n"[,)]'
|
|
Run this command:
git grep -l 'LC_[A-Z]*="' \
| xargs perl -pi -e 's/(LC_[A-Z]*)="(.*?)"/$1=$2/'
* src/Makefile.am: Write LC_ALL=$$locale, not LC_ALL="$$locale".
* src/date.c (main): Similar, in a comment.
* tests/misc/sort-month: Write LC_ALL=$LOC, not LC_ALL="$LOC".
|
|
* src/sort.c (key_warnings): Always warn about significant leading
blanks when character offsets are specified, unless they key is
possibly a line offset, i.e. of the form -k1.x,1.y. Also suppress
this warning if the user could be sorting right aligned indexes.
|
|
* NEWS (New features): Mention it.
* src/du.c (DEBUG_OPT): Remove. Use long-named ---debug instead.
Commented out.
(MAX_DEPTH_OPTION): Remove. Use 'd' instead.
(main): Insert literal "d:"; remove DEBUG_OPT.
* doc/coreutils.texi (du invocation): Add -d to indices.
* tests/du/max-depth: Exercise -d, too.
|
|
* src/Makefile.am (fs-def): Sort definitions.
This is required by fs-magic-compare's use of join.
|
|
* src/sort.c (mark_key): Add a cast-to-int of a printf field width,
to placate -Wformat.
|
|
* src/sort.c (usage): Mention --debug can output warnings to stderr.
Also split the translatable string to aid translation.
(default_key_compare): A new function refactored from main(),
and now also called from the new key_warnings() function.
(key_to_opts): A new function refactored from incompatible_options(),
and now also called from the new key_warnings() function.
(key_numeric): A new function refactored to test if key is numeric.
(key_warnings): A new function to output warnings to stderr,
about questionable use of various options. Currently it warns
about zero length keys and ineffective global options.
(incompatible_options): Refactor out key_to_opts()
(main): Use key_init() to initialize gkey. Refactor out
default_key_compare(). Call key_warnings() in debug mode.
* doc/coreutils.texi (sort invocation): Mention that warnings
are output by --debug.
* tests/misc/sort-debug-warn: A new test for debug warnings.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the new feature
|
|
* src/sort (usage): Add description for --debug.
(write_bytes): Pass a line structure so it can subsequently
be passed to compare to highlight the keys when in debug mode.
Also transform TAB and NUL characters written to stdout so
that the highlighting in debug mode aligns correctly.
(human_numcompare): Pass an "endptr" so we can record the extent
of the number matched.
(general_numcompare): Likewise.
(find_unit_order): Likewise.
(getmonth): Likewise.
(numcompare): Likewise. Note we reuse find_unit_order() for this,
which is a good enough approximation, and means we don't need to
change the strnumcmp() interface.
(check_mixed_SI_IEC): Return whether iec_present, so that can be
used to set the "endptr" in find_unit_order. Also make the key
parameter optional, which will be the case from numcompare().
(count_tabs): A new function to determine how much to adjust
the mbswidth() values by (TABs don't have a width).
(mark_key): A new function to output the key highlighting to stdout.
(debug_key): A new function to determine the offset and width
of the key highlighting.
(key_compare): Pass the show_debug parameter so the key highlighting
is only displayed when explicitly called. For each key type, set
the length (lena) and whether leading blanks are auto skipped (skipb)
which are then used by debug_key() to highlight the portion of the
key used in the comparison.
(compare): Pass the show_debug parameter so the key highlighting
is only displayed when explicitly called. Call debug_key() to
highlight the last resort comparison.
(check): Output highlighting for disorder line to stdout.
(main): Process the --debug option and make it mutually exlusive
with the -o option as I don't see it useful there, even potentially
harmful if someone left a --debug in by mistake when updating a file.
Also restricting debug output to stdout, simplifies the logic
for dealing with temporary files.
* doc/coreutils.texi (sort invocation): Describe the --debug option,
and reference it from the --key description.
* tests/misc/sort-debug-keys: A new test for highlighting keys.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the new feature.

* src/sort.c (general_numcompare): Don't use long double if strtold
is not available, as it may introduce needless overhead.
|
|
* src/sort.c (general_numcompare): Use long doubles unconditionally,
and strtold when available, to convert numbers with greater range and
precision. Performance was seen to be on par with standard doubles.
* doc/coreutils.texi (sort invocation): Amend the -g description to
mention long double rather than double, and strtold rather than strtod.
* src/getlimits.c (main): Output floating point limits for use in tests.

doubles when possible, and that locale specific floats are handled.

The value of `$?' on entrance to signal handlers in shell scripts
cannot be relied upon, so set the exit code explicitly.

Necessary for cygwin. Technically, this patch is not correct,
in that it clobbers O_APPEND, but it is no different than any
other use of xfreopen to force binary mode, so all such uses
should be fixed at once in a later patch.
* src/base64.c (main): Open input in binary mode.
* THANKS: Update.

This regression was introduced in commit 224a69b5, 2009-02-24,
"sort: Fix two bugs with determining the end of field".
The specific regression being that we include 1 field too many when
an end field is specified using obsolescent key syntax (+POS -POS).
* src/sort.c (struct keyfield): Clarify the description of the eword
member, as suggested by Alan Curry.
(main): When processing obsolescent format key specifications,
normalize eword to a zero based count when no specific end char is given
for an end field. This matches what's done when keys are specified with -k.
* tests/misc/sort: Add a few more tests for the obsolescent key formats,
with test 07i being the particular failure addressed by this change.
* THANKS: Add Alan Curry who precisely identified the issue.
* NEWS: Mention the fix.

* NEWS: Mention the fix.

* src/copy.c (copy_reg): Suppress SELinux ENOTSUP warnings consistently
between the destination being present or not. Previously we did
not suppress ENOTSUP messages when the destination was present.
(copy_internal): Use the same ENOTSUP supression method as
copy_reg() even though the issue was not seen in this case.
* tests/cp/cp-a-selinux: Add a test case for the issue and
group the other test cases in the file more coherently.
* tests/cp/cp-mv-enotsup-xattr: Do the same check for xattr
warnings, even though they did not have the issue.
|
|
The 2010-03-26 commit, 4c38625e, "doc: fix info on cp --preserve..."
was not entirely correct as cp --preserve=all does produce some
xattr warnings.
* src/copy.h: Update and clarify the comments for reduce_diagnostics
and require_preserve_{xattr,context}.
* doc/coreutils.texi (cp invocation): Update the -a and
--preserve=xattr,context options to say when and which
xattr warnings are output.
(mv invocation): Mention that some warnings are output
when preserving xattrs.

* src/dircolors.hin: Add them.

Now that even MinGW provides ftruncate, we know that all
reasonable portability targets provide this function.
Remove the workaround code. We nearly removed the gnulib
module three years ago:
http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/9203
and it is now officially "obsolete".
* bootstrap.conf (gnulib_modules): Remove ftruncate.
* src/copy.c (copy_reg): Remove use of HAVE_FTRUNCATE and its
no-longer-used workaround code.
* src/truncate.c: Remove a comment about handling missing ftruncate.
|
|
* src/wc.c (usage): Add wc's definition of "word".
|
|
* src/tail.c [HAVE_INOTIFY && !HAVE_SYS_STATFS_H]: Include <sys/vfs.h>.
|
|
* src/Makefile.am (AM_LDFLAGS): Define. Use gnulib's new
$(IGNORE_UNUSED_LIBRARIES_CFLAGS).

Related to the 2010-03-25 commit, 88d4b346,
"timeout: use more standard option parsing".
* src/nice.c (main): Don't use parse_long_options()
which is a helper for commands that don't have any
long options specific to them.

passes due to us accepting multiple instances of the
--help and --version options.

Based on a report from Kim Hansen who wanted to
send a KILL signal to the monitored command
when `timeout` itself received a termination signal.
Rather than changing such a signal into a KILL,
we provide the more general mechanism of sending
the KILL after the specified grace period.
* src/timeout.c (cleanup): If a non zero kill delay
is specified, (re)set the alarm to that delay, after
which a KILL signal will be sent to the process group.
(usage): Mention the new option. Separate the description
of DURATION since it's now specified in 2 places.
Clarify that the duration is an integer.
(parse_duration): A new function refactored from main(),
since this logic is now called for two parameters.
(main): Parse the -k option.
* doc/coreutils.texi (timeout invocation): Describe the
new --kill-after option and use @display rather than
@table to show the duration suffixes. Clarify that
a duration of 0 disables the associated timeout.
* tests/misc/timeout-parameters: Check invalid --kill-after.
* tests/misc/timeout: Check a valid --kill-after works.
* NEWS: Mention the new feature.
|
|
* src/remove.c (write_protected_non_symlink): If faccessat fails,
return 1 or -1 directly, rather than falling back on euidaccess*.
|
|
* src/sort.c: The units containing 'i' are actually IEC not SI.

Tell the system that we'll access input sequentially,
so that we more efficiently process uncached files in a few cases:
Reading from faster flash devices. E.g. 21 MB/s key:
NORMAL 31.6s (26.8 user)
SEQUENTIAL 27.7s
WILLNEED 27.7s
Processing in parallel with readahead when using a small 1M buffer:
NORMAL 24.7s (21.1 user)
SEQUENTIAL 22.7s
WILLNEED 25.6s
A small benefit when merging:
NORMAL 25.0s (16.9 user)
SEQUENTIAL 24.6s (16.6 user)
WILLNEED 38.4s (13.1 user)
Note WILLNEED is presented above for comparison to show it
has some unwanted characteristics due to its synchronous
prepopulation of the cache. It has a good benefit on a
mechanical disk @ 80MB/s and a multicore system with
competing processes:
NORMAL 14.73s
SEQUENTIAL 10.95s
WILLNEED 05.22s
However the scheduling differences causing this result
are probably best explicitly managed using `nice` etc.
* m4/jm-macros.m4 (coreutils_MACROS): check for posix_fadvise().
* src/sort.c (fadvise_input): A new function to apply
the POSIX_FADV_SEQUENTIAL hint to an input stream.
(stream_open): Call the above function for all input streams.
|
|
* src/sort.c (char fold_toupper[]): Change to unsigned
so as the correct comparisons are made in getmonth().
This fixes unibyte locales where abbreviated months
have characters that are > 0x7F, but it also works for
multibyte locales with the caveat that multibyte characters
are matched case sensitively.
With this change, the following example sorts correctly:
$ echo -e "1 márta\n2 Feabhra" | LANG=ga_IE.utf8 sort -k2,2M
2 Feabhra
1 márta
* src/sort.c (inittables): Since we ignore blanks around months
in the input, don't include them when they're present in the locale.
With this change, the following example sorts correctly:
$ echo -e "1 2月\n2 1月" | LANG=ja_JP.utf8 sort -k2,2M
2 1月
1 2月
* tests/misc/sort-month: A new test to exercise the above cases.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the fix.
