* doc/coreutils.texi (Standards conformance): Give value of
_POSIX2_VERSION matching the _POSIX_C_SOURCE of POSIX 2008.
|
|
Make GNU coreutils' test recognize "==" as a synonym for "=".
This is already the case in GNU coreutils' expr, bash, ksh,
busybox ash, FreeBSD-current /bin/sh and /bin/test, and
OpenBSD's /bin/sh.
Before, env test a '==' a would fail with this diagnostic:
"test: ==: binary operator expected". Now, it succeeds.
* src/test.c: Accept "==" as a synonym for "=".
* doc/coreutils.texi (String tests): Document it.

* src/dd.c (FFS_MASK): A new macro (Find First Set) refactored
from the following enum as it's now used twice.
(usage): Mention the new 'nocache' flag.
(cache_round): A new function to help ignore requests
to drop cache, that are less than page_size.
(invalidate_cache): A new function to call posix_fadvise()
with the appropriate offset and length. Note we don't
use fdadvise() so we can detect errors when count=0.
(dd_copy): Call invalidate_cache() for the portions read.
(iwrite): Likewise for the portions written.
(main): Call invalidate_cache for page_size slop or
for full file when count=0.
* cfg.mk (sc_dd_O_FLAGS): Adjust to pass.
* doc/coreutils.texi (dd invocation): Describe the 'nocache' flag,
and give some examples of how it can be used.
* tests/dd/nocache: A new test.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the new feature.
|
|
* doc/coreutils.texi (dd invocation): Clarify that bs= can
cause parital reads to be immediately written to output.
* src/dd.c (usage): Hint that bs= can cause partial writes.
See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8171
|
|
* src/dd.c (usage): Move 'sync' up with other data transformation
options. Having it alongside 'fsync' and 'fdatasync' is
particularly confusing. Also the double line description of
the 'sync' option, serves as a visual break from the "flag"
type options that follow.
* doc/coreutils.texi (dd invocation): Apply the same grouping
as above, by splitting the "conv=" table in two.
|
|
* doc/coreutils.texi (cut invocation): Remove the tr -s '[:blank:]'
example, as it doesn't handle leading and trailing blanks. Add `awk`
examples for common field processing operations often asked about.
Also document a `join` hack, to achieve the same thing. Note the
join options are ordered so as to be compatible with other systems.
|
|
This allows one to use join as a field extractor like:
join -a1 -o 1.3,1.1 - /dev/null
* src/join.c (join): Don't flag unpairable lines when
one of the files is empty.
* tests/misc/join: Add a new test for empty input, and adjust
a previous test that was only checking against empty input.
* doc/coreutils.texi (join invocation): Document the change.
* NEWS: Likewise.
|
|
Lines with a different number of fields than the first line,
will be truncated or padded.
* src/join.c (prfields): A new function refactored from prjoin(),
to output all but the join field.
(prjoin): Don't swap line1 and line2 when line1 is blank
so that the padding is applied to the right place.
(main): Handle the -o 'auto' option.
* tests/misc/join: Add 6 new cases to test the auto format.
* NEWS: Mention the change in behavior.

* src/sort.c (main): If --parallel isn't specified,
restrict the number of threads to 8 by default.
If the --parallel option is specified, then

aliases for %u.
* src/csplit.c (FLAG_THOUSANDS, FLAG_ALTERNATIVE): New constants.
(get_format_flags): Now take char const * and int * and return
size_t. It now stores info about the flags instead of merely
scanning them. Also, it handles '0' correctly. Drop support for
the undocumented '+' and ' ' flags since the value is unsigned.
Add support for the (undocumented) "'" flag. All uses changed.
(get_format_width, get_format_prec): Remove.
(check_format_conv_type): Renamed from get_format_conv_type, with
a different signature. It now converts the format to one that is
compatible with unsigned int, and checks flags. All uses changed.
(max_out): Have snprintf compute the number of bytes needed rather
than attempting to do it ourselves (which doesn't work portably
with outlandish formats such as %4294967296d).
(check_format_conv_type, main): Check for overflow in size
calculations. Don't assume size_t fits in unsigned int.
* tests/misc/csplit: Check for proper handling of flags, with
%0#6.3x. Coreutils 8.6 mishandles this somewhat-weird example.

(print_stat, print_it, usage): Remove the %:X-style formats.
* tests/misc/stat-nanoseconds: Set TZ=UTC0 to avoid problems
with weird time zones. Use a time stamp near the Epoch so that we
don't have to worry about leap seconds. Redo test cases to match
new behavior.
* tests/touch/60-seconds: Change %Y.%:Y to %.9Y, to adjust to
new behavior.

This reverts part of the recent commit 9069af45,
"stat: print timestamps to full resolution", which made %X, %Y, %Z
print floating point numbers. We prefer to retain portability of
%X, %Y and %Z uses, while still providing access to full-resolution
time stamps via modified format strings. Also make the new
%W consistent.
* src/stat.c: Include "xstrtol.h".
(print_it): Accept a new %...:[XYZ] format directive,
e.g., %:X, to print the nanoseconds portion of the corresponding time.
For example, %3.3:Y prints the zero-padded, truncated, milliseconds
part of the time of last modification.
(print_it): Update print_func signature to match.
(neg_to_zero): New helper function.
(epoch_time): Remove function; replace with...
(epoch_sec): New function; use timetostr.
(out_ns): New function. Use "09" only when no other modifier
is specified.
(print_statfs): Change type of "m" to unsigned int,
now that it must accommodate values larger than 255.
(print_stat): Likewise.
Map :X to a code of 'X' + 256. Likewise for Y, Z and W.
(usage): Update.
* tests/touch/60-seconds: Use %Y.%:Y in place of %Y.

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

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.

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

(usage, long_options, main): New option, --parallel.
(specify_nthreads): New function.

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.

* 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): 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.
* tests/misc/sort-float: A new test to ensure sort is using long
doubles when possible, and that locale specific floats are handled.
* tests/Makefile.am: Reference the new test.
* tests/test-lib.sh (getlimits_): Normalize indenting.
* NEWS: Mention the new behaviour.

* doc/coreutils.texi (factor invocation): Don't say that "factoring
large prime numbers is hard". A pedant might ding you, since it's
trivial to factor a number that is known to be prime. Instead, say
that "factoring large numbers... is hard". Reported by Andreas Eder.
