https://git.shady.money/coreutils/atom?h=v8.72010-07-22T00:04:47Zprovide POSIX_FADV_SEQUENTIAL hint to appropriate utils2010-07-22T00:04:47ZPádraig BradyP@draigBrady.com2010-07-20T17:51:01Zurn:sha1:47076e3c7c22fc7557f388ad3d47228b922da71e
Following on from commit dae35bac, 01-03-2010,
"sort: inform the system about our input access pattern"
apply the same hint to all appropriate utils.
This currently gives around a 5% speedup for reading
large files from fast flash devices on GNU/Linux.

doc: make wc --help say how it defines a 'word'2010-04-08T21:53:12ZJames Youngmanjay@gnu.org2010-04-08T09:58:52Zurn:sha1:0a9302e7f796bc59a17f85fed00f0350c8330e12
* src/wc.c (usage): Add wc's definition of "word".

wc: line-buffer the printed counts2009-12-23T13:45:34ZPádraig BradyP@draigBrady.com2009-12-22T07:36:12Zurn:sha1:11dc0016bb72372bbd46b964fb57f4d10448225a
* src/wc.c (main): Set stdout to line buffered mode
to ensure parallel running instances don't intersperse
their output. This adds 6.5% to the run time in the worst case
of many zero length files, but has neglible impact for
standard sized files.
* tests/misc/wc-parallel: New test for atomic output.
* tests/Makefile.am: Reference it.
* NEWS: Mention the fix
This is similar to commit 710fe413, 20-10-2009,
"md5sum, sha*sum, sum: line-buffer the printed checksums"
maint: Use logical rather than bitwise operators on bools2009-09-23T13:33:40ZPádraig BradyP@draigBrady.com2009-09-23T09:10:51Zurn:sha1:a037e838e15c9a698f1634398e0fe2726398d575
This is because bitwise operators are:
- confusing and inconsistent in a boolean context
- non short circuiting
- brittle in C89 where bool can be an int (so > 1)
doc: mention the texinfo documentation in --help2009-09-21T11:37:57ZPádraig BradyP@draigBrady.com2009-09-18T22:06:21Zurn:sha1:5d4f09d83a7c69110b4db97443759e9046c149e1
* src/system.h: Rename emit_bug_reporting_address() to
emit_ancillary_info() and update it to not print the translation
project address in en_* locales, and _do_ print it in the 'C'
(and other) locales so that it's included in the default man page.
Also mention how to invoke the texinfo documentation for each command.
Also move the "hard-locale.h" include to the 8 files that now use it.
* man/help2man: Strip the newly added texinfo reference from the
--help output as a more verbose version is already added by help2man.

cleanup/modernize: don't test HAVE_MBRTOWC; now gnulib provides it2009-01-01T01:15:07ZJim Meyeringmeyering@redhat.com2008-12-23T18:06:31Zurn:sha1:92465d59c678c5a8e8c4c0985eb6ecec4c391df9
* bootstrap.conf (gnulib_modules): Include mbrtowc explicitly.
* src/ls.c (quote_name): Don't test HAVE_MBRTOWC, now that we're
guaranteed to have the function.
* src/wc.c (wc): Likewise.
wc: read and process --files0-from= input a name at a time,2008-12-02T12:12:22ZJim Meyeringmeyering@redhat.com2008-11-25T17:38:26Zurn:sha1:c2e56e0de7d86bdc0f824d758a7efde4d5d7b235
when the file name list is not too large. Before, wc would always read
the entire file name list into memory and *then* process each file name.
wc does read the list into memory when the list is known not to be too
large; this is done in order to be able to align the output numbers,
as it does with arguments specified on the command-line
* src/wc.c: Include "argv-iter.h".
(main): Rewrite to use argv-iter when the input file name list
is known to be too large.
* NEWS (Bug fixes): Mention it.
