1 document the following in coreutils.texi:
8 Also document the SELinux changes.
10 comm: add an option, --output-delimiter=STR
11 Files to change: src/comm.c, ChangeLog, NEWS, doc/coreutils.texi,
12 Add a new file, tests/misc/comm (use another file in that directory as
13 a template), to exercise the new option. Suggestion from Dan Jacobson.
16 Now that gnulib supports *printf("%a"), import one of the
17 *printf-posix modules so that printf(1) will support %a even on
18 platforms where the native *printf(3) is deficient.
19 Suggestion from Eric Blake.
21 renice: POSIX utility, needs implementing.
22 suggestion from Karl Berry (among others).
24 install: add an option to specify the program used to strip binaries.
25 suggestion from Karl Berry
28 Address this comment: FIXME: mv's behavior in this case is system-dependent
29 Better still: fix the code so it's *not* system-dependent.
31 ls: add --format=FORMAT option that controls how each line is printed.
33 cp --no-preserve=X should not attempt to preserve attribute X
34 reported by Andreas Schwab
36 copy.c: Address the FIXME-maybe comment in copy_internal.
37 And once that's done, add an exclusion so that `cp --link'
38 no longer incurs the overhead of saving src. dev/ino and dest. filename
41 See if we can be consistent about where --verbose sends its output:
42 These all send --verbose output to stdout:
43 head, tail, rm, cp, mv, ln, chmod, chown, chgrp, install, ln
44 These send it to stderr:
48 Write an autoconf test to work around build failure in HPUX's 64-bit mode.
49 See notes in README -- and remove them once there's a work-around.
51 Integrate use of sendfile, suggested here:
52 http://mail.gnu.org/archive/html/bug-fileutils/2003-03/msg00030.html
53 I don't plan to do that, since a few tests demonstrate no significant benefit.
55 Should printf '\0123' print "\n3"?
56 per report from TAKAI Kousuke on Mar 27
57 http://mail.gnu.org/archive/html/bug-coreutils/2003-03/index.html
59 printf: consider adapting builtins/printf.def from bash
61 df: add `--total' option, suggested here http://bugs.debian.org/186007
63 seq: give better diagnostics for invalid formats:
64 e.g. no or too many % directives
65 seq: consider allowing format string to contain no %-directives
67 tail: don't use xlseek; it *exits*.
68 Instead, maybe use a macro and return nonzero.
70 tr: support nontrivial equivalence classes, e.g. [=e=] with LC_COLLATE=fr_FR
72 lib/strftime.c: Since %N is the only format that we need but that
73 glibc's strftime doesn't support, consider using a wrapper that
74 would expand /%(-_)?\d*N/ to the desired string and then pass the
75 resulting string to glibc's strftime.
77 unexpand: [http://www.opengroup.org/onlinepubs/007908799/xcu/unexpand.html]
78 printf 'x\t \t y\n'|unexpand -t 8,9 should print its input, unmodified.
79 printf 'x\t \t y\n'|unexpand -t 5,8 should print "x\ty\n"
81 Let GNU su use the `wheel' group if appropriate.
82 (there are a couple patches, already)
84 sort: Investigate better sorting algorithms; see Knuth vol. 3.
86 We tried list merge sort, but it was about 50% slower than the
87 recursive algorithm currently used by sortlines, and it used more
88 comparisons. We're not sure why this was, as the theory suggests it
89 should do fewer comparisons, so perhaps this should be revisited.
90 List merge sort was implemented in the style of Knuth algorithm
91 5.2.4L, with the optimization suggested by exercise 5.2.4-22. The
92 test case was 140,213,394 bytes, 426,4424 lines, text taken from the
93 GCC 3.3 distribution, sort.c compiled with GCC 2.95.4 and running on
94 Debian 3.0r1 GNU/Linux, 2.4GHz Pentium 4, single pass with no
95 temporary files and plenty of RAM.
97 Since comparisons seem to be the bottleneck, perhaps the best
98 algorithm to try next should be merge insertion. See Knuth section
99 5.3.1, who credits Lester Ford, Jr. and Selmer Johnson, American
100 Mathematical Monthly 66 (1959), 387-389.
102 cp --recursive: perform dir traversals in source and dest hierarchy rather
103 than forming full file names. The latter (current) approach fails
104 unnecessarily when the names become very long.
106 Remove suspicious uses of alloca (ones that may allocate more than
109 Adapt these contribution guidelines for coreutils:

113 Changes expected to go in, someday.
114 ======================================
116 dd patch from Olivier Delhomme
118 Andreas Gruenbacher's xattr changes
120 Apply Bruno Haible's hostname changes
122 test/mv/*: clean up $other_partition_tmpdir in all cases
124 ls: when both -l and --dereference-command-line-symlink-to-dir are
125 specified, consider whether to let the latter select whether to
126 dereference command line symlinks to directories. Since -l has
127 an implicit --NO-dereference-command-line-symlink-to-dir meaning.
128 Pointed out by Karl Berry.
130 A more efficient version of factor, and possibly one that
131 accepts inputs of size 2^64 and larger.
133 dd: consider adding an option to suppress `bytes/block read/written'
134 output to stderr. Suggested here:

138 ------------------------
139 ls --color: Ed Avis' patch to suppress escape sequences for
140 non-highlighted files
142 getpwnam from Bruce Korb
144 pb (progress bar) from Miika Pekkarinen
146 ------------------------------
148 Remove long-deprecated options. Search case-insensitive for
149 `deprecated' and `remove in '. Automate this.
151 Add a distcheck-time test to ensure that every distributed
152 file is either read-only(indicating generated) or is
153 version-controlled and up to date.
155 Implement Ulrich Drepper's suggestion to use getgrouplist rather
156 than getugroups. This affects only `id', but makes a big difference
157 on systems with many users and/or groups, and makes id usable once
158 again on systems where access restrictions make getugroups fail.
159 But first we'll need a run-test (either in an autoconf macro or at
160 run time) to avoid the segfault bug in libc-2.3.2's getgrouplist.
161 In that case, we'd revert to using a new (to-be-written) getgrouplist
162 module that does most of what `id' already does. Or just avoid the
163 buggy use of getgrouplist by never passing it a buffer of length zero.
164 See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200327
166 remove `%s' notation:
167 grep -E "\`%.{,4}s'" src/*.c
169 remove or adjust chown's --changes option, since it
170 can't always do what it currently says it does.
172 Adapt tools like wc, tr, fmt, etc. (most of the textutils) to be
173 multibyte aware. The problem is that I want to avoid duplicating
174 significant blocks of logic, yet I also want to incur only minimal
175 (preferably `no') cost when operating in single-byte mode.
177 Remove all uses of the `register' keyword
179 pr's use of nstrftime can make it malloc a very large (up to SIZE_MAX) buffer
181 ls.c: use gettime rather than clock_gettime, gettimeofday, time
