* src/tac.c (main): Reading a line longer than 16KiB would cause
tac to realloc its primary buffer. Then, just before exit, tac
would mistakenly free the original (now free'd) buffer.
This bug was introduced by commit be6c13e7, "maint: always free a
buffer, to avoid even semblance of a leak".
* NEWS (Bug fixes): Mention it.
* tests/misc/tac (double-free): New test, to exercise this.
Reported by Salvo Tomaselli in <http://bugs.debian.org/594666>.

* tests/ls/readdir-mountpoint-inode: Check to see if skip_test_ is
called in a helper function via $() instead of mistakenly failing.
* THANKS: Update.

* NEWS: Document this.
* src/sort.c (getmonth): Omit LEN arg, as MONTH is now null-terminated.
(compare_random): Don't null-terminate keys, as caller now does that.
(compare_version): Remove.
(debug_key): Null-terminate string for getmonth.
(keycompare): Support combining -R with any of -d, -f, -i, -V.
Also, support combining -V with any of -d, -i.
(check_ordering_compatibility): Allow newly-supported combinations.
* tests/misc/sort (02q, 02r, 02s): New tests, for new combinations.
(incompat2): Now test -nR, since -fR are now compatible.

Formerly, the 'compare' function and some of its subroutines had a
debugging flag, which caused them to output underlines. This
change refactors the code so that debugging output is
more-separated from the actual sorting. In the process, the
change fixes a minor error in the debugging output. The change
shortens the source code and executable size a tad, and improves
CPU performance by 2.4% on my platform with a simple benchmark (C
locale, line sorting, no debug).
* src/sort.c (long_double, strtold): Move back to prelude, since
they're now used by multiple functions again.
(unit_order): Move to file scope, since it's now used by two functions.
(find_unit_order, human_numcompare, numcompare, general_numcompare):
Remove endptr parameter. All callers changed.
(human_numcompare): Args are now const pointers.
(getmonth): Endptr is now non-const.
(key_numeric): Move up, since it's needed earlier.
(debug_key): Take a line and a key as argument, instead of having
the caller figure out where the field is.
(debug_line): New function.
(keycompare, compare): Omit debug parameter; debug output now done
elsewhere. All callers changed.
(write_line): Renamed from write_bytes; all callers changed.
Use debug_line (not 'compare') to output debug info.
Use a slightly faster check for whether output file is stdout.
(check): Don't do debugging output; it's not that useful here,
and it confuses the code.
(main): Check for incompatibility between -c and --debug.
Use standard diagnostic for incompatible options.
* tests/misc/sort-debug-keys: Fix test case: "--Mi-1" is not
a number, so its first character should not be underlined when
debugging a numeric sort.
|
|
* tests/init.sh (setup_): Move exit trap outside of shell function.
This patch is imported from gnulib.
|
|
* src/sort.c (debug_width): New function, which does not stop
counting tabs at \0, and also invokes mbsnwidth. Stamp out strnlen!
(count_tabs): Remove.
(debug_key): Use debug_width instead of mbsnwidth and count_tabs.
* tests/misc/sort-debug-keys: Check that \0 and \t intermix.
|
|
* NEWS: Document changes to sort -h, which are now minor with
respect to the pre-July-30th version.
* doc/coreutils.texi (sort invocation): Likewise. The
documentation now describes how -h comparison is done rather than
being vague with border cases.
* src/sort.c (long_double, strtold): Move back to general_numcompare.
(LD, compute_human): Remove.
(find_unit_order): Remove THOU_SEP parameter, since thousands
separators are now allowed by all callers. Revert to previous
behavior of sorting by suffix, and returning the order rather than
2 * order + binary, since we no longer care whether binary powers
are being used. However, treat all zeros the same, instead of
sorting 0M before 0G; this is more consistent with the desired
behavior of sorting -1G before -1M.
* tests/misc/sort (h1, h3, h6): Adjust to match mostly-reverted
behavior. However, check that all zeros sort together.
* tests/misc/sort-debug-keys: Omit a "_", since the trailing "i"
in "1234Gi" is no longer part of the key.
|
|
* NEWS: Document changes to sort -h.
* doc/coreutils.texi (sort invocation): Likewise.
* src/sort.c (long_double, strtold): Move to prelude, since they're
now used by multiple functions.
(LD): New macro.
(struct keyfield.iec_present): Remove this member. All uses removed.
(check_mixed_SI_IEC): Remove. This code was busted in the presence
of multiple threads, as it had a race condition.
(find_unit_order): Remove arg KEY; add arg THOU_SEP; arg ENDPTR is
now char ** rather than char const **. Return an integer that
distinguishes decimal from binary powers. Parse the number
consistently with the intersection of strtold and strnumcmp.
Set *ENDPTR unconditionally.
(compute_human): New static function.
(human_numcompare): Remove arg KEY. Remove 'const' from other args.
Use strnumcmp if possible, but fall back on floating point if not.
(numcompare, general_numcompare): Arg EA is now char ** rather
than char const **.
(numcompare): Adjust to new find_unit_order signature and behavior.
(keycompare): Adjus to new human_numcompare signature.
* tests/misc/sort (h1, h3, h4, h6): Adjust to new behavior.
* tests/misc/sort-debug-keys: Likewise.

* src/sort.c (fillbuf): Don't append eol unless the line is nonempty.
This fixes a bug that was partly but not completely fixed by
the aadc67dfdb47f28bb8d1fa5e0fe0f52e2a8c51bf commit (dated July 15).
* tests/misc/sort (realloc-buf-2): New test, which catches this
bug on 64-bit hosts.
|
|
* src/du.c (process_file): Avoid recalculation of hashes
and of file-exclusion for directories. Do not descend into
the same directory more than once, unless -l is given; this is faster.
Calculate stat buffer lazily, since it
need not be computed at all for excluded files.
Count space if FTS_ERR, since stat buffer is always valid then.
No need for 'print' local variable.
(main): Use FTS_NOSTAT. Use FTS_TIGHT_CYCLE_CHECK only when not
hashing everything, since process_file finds cycles on its own
when hashing everything.
* tests/du/deref: Add test cases for -L bugs.
|
|
* tests/misc/sort-merge-fdlimit: This test was written assuming that
-R typically opens /dev/urandom, but that's no longer the case.
Redo test to specify a random source; this resurrects the point of
checking for file descriptor exhaustion. Also try plain -R, since
that implementation may change in the future too.

* tests/Makefile.am (TESTS): Add misc/sort-unique.
* tests/misc/sort-unique: New file.

This patch is by Gene Auyeung, Chris Dickens, Chen Guo, and Mike
Nichols, based off of a patch by Paul Eggert, Glen Lenker, et. al.,
with a basic heap implementation based off of the GDSL heap,
originally by Nicolas Darnis.
The number of sorts done in parallel is limited to the number
of available processors by default, or can be further restricted
with the --parallel option.
On a dual-die, 8 core Intel Xeon, results show sorting with
8 threads is almost 4 times faster than using a single thread.
Timings when sorting a 96MB file:
THREADS TIME (s)
1 5.10
2 2.87
4 1.75
8 1.31
Single threaded sorting has also been improved,
especially for cheaper comparison operations:
COMMAND BEFORE (s) AFTER (s)
sort 8.822 8.716
sort -g 10.336 10.222
sort -n 3.077 2.961
LANG=C sort 2.169 2.066

(struct merge_node): New struct.
(struct merge_node_queue): New struct.
(sortlines temp): Remove declaration.
(usage, long_options, main): New option, --parallel.
(specify_nthreads): New function.
(mergelines): New signature, to emphasize the fact that the HI area
must be part of the destination. All callers changed.
(sequential_sort): New function, renamed from sortlines. Merge in
the functionality of sortlines_temp.

* tests/init.cfg: Introduce a retry_delay_() function to
repeatedly call a test function that requires a delay.
This delay can now be shorter for the common case on fast
systems, but will double until a configurable limit it reached

Refactor the SELinux error handling code a little and display all
SELinux errors when only copying attributes.

Previously we defaulted to "long-iso" format in locales without
specific format translations, like the en_* locales for example.
This reverts part of commit 6837183d, 08-11-2005, "ls ... acts like
--time-style='posix-long-iso' if the locale settings are messed up"
* src/ls.c (decode_switches): Only use the ISO format when specified.
* NEWS: Mention the change in behavior.

* tests/tail-2/inotify-rotate: Switch to new init.sh-based framework.
(grep_timeout): New function.
Use it in place of open-coded loops that might infloop.
This was prompted by my encountering an inexplicable, and so far
unreproducible, infloop in the code that was waiting for "b" to
appear in "out".
|

From there, they will be used by both test-lib.sh (as we phase it out)
and the newer init.sh, to which all tests will migrate.
* tests/test-lib.sh: Move most functions from here, ...

* tests/misc/unexpand: Likewise.
* tests/misc/uniq: Likewise.

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

* tests/misc/help-version: Add init code for GNU Parted.
|
|
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".
|
|
* tests/misc/sort-month: Remove the -b option which
is redundant and ignored.
|
|
* 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.
|
|
* tests/misc/mktemp: Change punctuation to make copyright
paragraph consistent with all of the others.
|
|
* tests/cp/cp-a-selinux: Initialize skip, to avoid a syntax error
in subsequent "test".
Remove redirect-to-/dev/null, now that output is always to a log file.
|
|
* 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.
|

of the French UTF8 locale.
|
|
* tests/init.sh: Update from gnulib.
|
|
* 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
|
|
* tests/misc/sort-debug-keys: Don't verify (or even run)
the fr_FR tests when that locale is not available on the system.
|
|
* 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.

* 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.

The value of `$?' on entrance to signal handlers in shell scripts

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.

* tests/cp/capability: A new root test.
* tests/Makefile.am (root_tests): Reference the new test.
* NEWS: Mention the fix.
|
|
* tests/ls/color-norm: Use the "time" output by `ls -l`
to check normal style. Previously we used the size from `ls -s`,
but the size of "empty" files can vary depending on whether
SELinux is enabled for example.
|
|
* tests/ls/capability: Adjust this test not to expect the no-op escape
sequence that was removed from all other tests by 2010-01-30 commit
5d43617e, "ls --color: don't emit a final no-op escape sequence".
