https://git.shady.money/coreutils/atom?h=v8.82010-07-22T00:04:47Zprovide 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.

maint: don't emit an extra newline in each of two diagnostics2010-05-25T16:05:29ZJim Meyeringmeyering@redhat.com2010-05-25T16:05:29Zurn:sha1:5d59808a65dc05c2777afb4b78128ca9db1ea78f

build: consistently use freopen-safer2009-11-07T17:10:28ZEric Blakeebb9@byu.net2009-11-05T23:48:09Zurn:sha1:56b85e035b77e48e7ec241b54da3f9c9d19e77d5
cat, head, ptx, shuf, tac, tail, tee, tr, and uniq used freopen
on stdout, and were potentially vulnerable. dircolors, du, and
tsort only used it on stdin, which is unaffected by freopen_safer,
but this covers all uses for consistency.
* cfg.mk (sc_require_stdio_safer): New rule.
* gl/modules/xfreopen (Depends-on): Add freopen-safer.
* gl/lib/xfreopen.c (includes): Use stdio--.h.
* src/ptx.c (includes): Likewise.
* src/shuf.c (includes): Likewise.
* src/uniq.c (includes): Likewise.
* src/dircolors.c (includes): Likewise.
* src/du.c (includes): Likewise.

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.

Suggestion from Steven Schveighoffer at:
http://savannah.gnu.org/patch/?6797
to greatly speed up the random passes done by shred.
* gl/lib/randread.c: Default to using the internal
pseudorandom generator, rather than reading /dev/urandom
* src/shred.c (usage): remove mention of /dev/urandom
* src/shuf.c (usage); ditto
* src/sort.c (usage): ditto
* doc/coreutils.text: Document the new behaviour
for aquiring random data.
