before embarking on a big project.
==================================================
+Modify chmod so that it does not change an inode's st_ctime
+ when the selected operation would have no other effect.
+ First suggested by Hans Ecke <http://hans.ecke.ws> in
+ http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/2920
+ Discussed more recently on <http://bugs.debian.org/497514>.
+
document the following in coreutils.texi:
runcon
chcon
mktemp
[
pinky
- uptime
Also document the SELinux changes.
-comm: add an option, --output-delimiter=STR
- Files to change: src/comm.c, ChangeLog, NEWS, doc/coreutils.texi,
- Add a new file, tests/misc/comm (use another file in that directory as
- a template), to exercise the new option. Suggestion from Dan Jacobson.
+Suggestion from Paul Eggert:
+ More generally, there's not that much use for imaxtostr nowadays,
+ since the inttypes module and newer versions of gettext allow things
+ like _("truncating %s at %" PRIdMAX " bytes") to work portably.
+ I suspect that (if someone cares to take the time) we can remove
+ all instances of imaxtostr and umaxtostr in coreutils and gnulib.
+
+cp --recursive: use fts and *at functions to perform directory traversals
+ in source and destination hierarchy rather than forming full file names.
+ The latter (current) approach fails unnecessarily when the names
+ become very long, and requires space and time that is quadratic in the
+ depth of the hierarchy. [Bo Borgerson is working on this]
printf:
Now that gnulib supports *printf("%a"), import one of the
df: add `--total' option, suggested here http://bugs.debian.org/186007
-seq: consider allowing format string to contain no %-directives
-
tail: don't use xlseek; it *exits*.
Instead, maybe use a macro and return nonzero.

Remove suspicious uses of alloca (ones that may allocate more than
about 4k)
Adapt these contribution guidelines for coreutils:
http://sources.redhat.com/automake/contribute.html
+Improve test coverage.
+ See HACKING for instructions on generating an html test coverage report.
+ Find a program that has poor coverage and improve.
Changes expected to go in, someday.

an implicit --NO-dereference-command-line-symlink-to-dir meaning.
Pointed out by Karl Berry.
- A more efficient version of factor, and possibly one that
- accepts inputs of size 2^64 and larger.
-
dd: consider adding an option to suppress `bytes/block read/written'
output to stderr. Suggested here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=165045
file is either read-only(indicating generated) or is
version-controlled and up to date.
-Implement Ulrich Drepper's suggestion to use getgrouplist rather than
- getugroups. This affects both `id' and `setuidgid', but makes a big
- difference on systems with many users and/or groups, and makes id usable
- once again on systems where access restrictions make getugroups fail.
- But first we'll need a run-test (either in an autoconf macro or at
- run time) to avoid the segfault bug in libc-2.3.2's getgrouplist.
- In that case, we'd revert to using a new (to-be-written) getgrouplist
- module that does most of what `id' already does. Or just avoid the
- buggy use of getgrouplist by never passing it a buffer of length zero.

+remove `%s' notation (now that they're all gone, add a maint.mk sc_

remove or adjust chown's --changes option, since it
can't always do what it currently says it does.
+Support arbitrary-precision arithmetic in those tools for which it
+makes sense. Factor and expr already support this via libgmp.
+The "test" program is covered via its string-based comparison of
+integers. To be converted: seq.

Adapt tools like wc, tr, fmt, etc. (most of the textutils) to be
multibyte aware. The problem is that I want to avoid duplicating
significant blocks of logic, yet I also want to incur only minimal
projects / platform / upstream / coreutils.git / blobdiff
