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.
* tests/misc/stat-nanoseconds: New file.
* tests/Makefile.am (TESTS): Add it.
* NEWS (Changes in behavior): Mention this.
With improvements by Pádraig Brady.

* src/tail.c (tail_forever_inotify): Handle the case where
tail --follow=name with inotify, is not able to add a watch on
a specified directory. This may happen due to inotify resource
limits or if the directory is currently missing or inaccessible.
In all these cases, revert to polling which will try to reopen
the file later. Note inotify returns ENOSPC when it runs out
of resources, and instead we report a particular error message,
lest users think one of their file systems is full.
(main): Document another caveat with using inotify, where we
currently don't recheck directories recreated after the
initial watch is setup.
* tests/tail-2/F-vs-rename: Fix the endless loop triggered by
the above issue.
* tests/tail-2/inotify-hash-abuse: Likewise.
* tests/tail-2/wait: Don't fail in the resource exhaustion case.
* tests/tail-2/F-vs-missing: A new test for this failure mode

which returned ENOSPC constantly from inotify_add_watch().
* NEWS: Mention the fix.

This valid translation spec aborted:
LC_ALL=en_US.iso-8859-1 tr '[:upper:]- ' '[:lower:]_'
This invalid translation spec aborted:
LC_ALL=en_US.iso-8859-1 tr '[:upper:] ' '[:lower:]'
This was caused by commit 6efd1046, 05-01-2008,
"Avoid tr case-conversion failure in some locales"
This misaligned conversion spec was allowed:
LC_ALL=C tr 'A-Y[:lower:]' 'a-z[:upper:]'
This was caused by commit af5d0c36, 21-10-2007,
"tr: do not reject an unmatched [:lower:] or [:upper:] in SET1"
This misaligned spec was allowed by extending the class:
LC_ALL=C tr '[:upper:] ' '[:lower:]'
* src/tr.c (validate_case_classes): A new function to check
alignment of case conversion classes. Also it adjusts the
length of the sets so that locales with different numbers of
upper and lower case characters, don't cause issues.
(string2_extend): Disallow extending the case conversion
class as in the above example. That is locale dependent
and most likely not what the user wants.
(validate): Do the simple test for "restricted" char classes
earlier, so we don't redundantly do more expensive validation.
(main): Remove the case class validation, and simplify.
* tests/misc/tr-case-class: A new test to test the various
alignment and locale issues, associated with case conversion.
* tests/misc/tr: Move case conversion tests to new tr-case-class.
* tests/Makefile.am: Reference the new test.

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
* bootstrap.conf: Add heap, pthread.
* coreutils.texi (sort): Describe the new --parallel option.

* gl/lib/heap.h: New file.
* gl/modules/heap: New file.

(MERGE_END, MERGE_ROOT): New constants.
(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.

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/init.cfg: ...to here. New file.

* 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): 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.

* src/copy.c (copy_reg): Copy xattrs _after_ setting file ownership
so that capabilities are not cleared when setting ownership.
* tests/cp/capability: A new root test.
* tests/Makefile.am (root_tests): Reference the new test.
* NEWS: Mention the fix.
|
|
* 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.

Output the NORMAL attribute before non file name text.
This attribute will continue into file names that would
not otherwise be colored unless FILE is also set.
The regression was introduced with commit 483297d5, 28-02-2009,
"ls --color no longer outputs unnecessary escape sequences".
* src/ls.c (set_normal_color): A new function to output the
NORMAL attribute sequence if it's enabled.
(print_current_files): Output NORMAL before printing long format info.
(print_file_name_and_frills): Output NORMAL before printing file name.
(print_color_indicator): Reset the attributes before a file name with
attributes so that NORMAL attributes will not combine with them.
(print_name_with_quoting): Ensure attributes are reset after printing
the file name if NORMAL attributes were output.

Tailing forever and by-name (--follow=name, -F), tail would
