1 convert to use gnulib-tool
3 strip: add an option to specify the program used to strip binaries.
4 suggestion from Karl Berry
7 Address this comment: FIXME: mv's behavior in this case is system-dependent
8 Better still: fix the code so it's *not* system-dependent.
10 ls: add --format=FORMAT option that controls how each line is printed.
12 cp --no-preserve=X should not attempt to preserve attribute X
13 reported by Andreas Schwab
15 copy.c: Address the FIXME-maybe comment in copy_internal.
16 And once that's done, add an exclusion so that `cp --link'
17 no longer incurs the overhead of saving src. dev/ino and dest. filename
20 See if we can be consistent about where --verbose sends its output:
21 These all send --verbose output to stdout:
22 head, tail, rm, cp, mv, ln, chmod, chown, chgrp, install, ln
23 These send it to stderr:
27 Write an autoconf test to work around build failure in HPUX's 64-bit mode.
28 See notes in README -- and remove them once there's a work-around.
30 Integrate use of sendfile, suggested here:
31 http://mail.gnu.org/archive/html/bug-fileutils/2003-03/msg00030.html
32 I don't plan to do that, since a few tests demonstrate no significant benefit.
34 Should printf '\0123' print "\n3"?
35 per report from TAKAI Kousuke on Mar 27
36 http://mail.gnu.org/archive/html/bug-coreutils/2003-03/index.html
38 printf: consider adapting builtins/printf.def from bash
40 df: add `--total' option, suggested here http://bugs.debian.org/186007
42 seq: give better diagnostics for invalid formats:
43 e.g. no or too many % directives
44 seq: consider allowing format string to contain no %-directives
46 resolve RH report on cp -a forwarded by Tim Waugh
48 tail: don't use xlseek; it *exits*.
49 Instead, maybe use a macro and return nonzero.
51 add mktemp? Suggested by Nelson Beebe
53 df: alignment problem of `Used' heading with e.g., -mP
54 reported by Karl Berry
56 tr: support nontrivial equivalence classes, e.g. [=e=] with LC_COLLATE=fr_FR
58 lib/strftime.c: Since %N is the only format that we need but that
59 glibc's strftime doesn't support, consider using a wrapper that
60 would expand /%(-_)?\d*N/ to the desired string and then pass the
61 resulting string to glibc's strftime.
63 sort: Compress temporary files when doing large external sort/merges.
64 This improves performance when you can compress/uncompress faster than
65 you can read/write, which is common in these days of fast CPUs.
66 suggestion from Charles Randall on 2001-08-10
68 unexpand: [http://www.opengroup.org/onlinepubs/007908799/xcu/unexpand.html]
69 printf 'x\t \t y\n'|unexpand -t 8,9 should print its input, unmodified.
70 printf 'x\t \t y\n'|unexpand -t 5,8 should print "x\ty\n"
72 Let GNU su use the `wheel' group if appropriate.
73 (there are a couple patches, already)
75 sort: Investigate better sorting algorithms; see Knuth vol. 3.
77 We tried list merge sort, but it was about 50% slower than the
78 recursive algorithm currently used by sortlines, and it used more
79 comparisons. We're not sure why this was, as the theory suggests it
80 should do fewer comparisons, so perhaps this should be revisited.
81 List merge sort was implemented in the style of Knuth algorithm
82 5.2.4L, with the optimization suggested by exercise 5.2.4-22. The
83 test case was 140,213,394 bytes, 426,4424 lines, text taken from the
84 GCC 3.3 distribution, sort.c compiled with GCC 2.95.4 and running on
85 Debian 3.0r1 GNU/Linux, 2.4GHz Pentium 4, single pass with no
86 temporary files and plenty of RAM.
88 Since comparisons seem to be the bottleneck, perhaps the best
89 algorithm to try next should be merge insertion. See Knuth section
90 5.3.1, who credits Lester Ford, Jr. and Selmer Johnson, American
91 Mathematical Monthly 66 (1959), 387-389.
93 cp --recursive: perform dir traversals in source and dest hierarchy rather
94 than forming full file names. The latter (current) approach fails
95 unnecessarily when the names become very long.
97 Remove suspicious uses of alloca (ones that may allocate more than

104 Changes expected to go in, someday.
105 ======================================
107 dd patch from Olivier Delhomme
109 Andreas Gruenbacher's xattr changes
111 Apply Bruno Haible's hostname changes
113 test/mv/*: clean up $other_partition_tmpdir in all cases
115 ls: when both -l and --dereference-command-line-symlink-to-dir are
116 specified, consider whether to let the latter select whether to
117 dereference command line symlinks to directories. Since -l has
118 an implicit --NO-dereference-command-line-symlink-to-dir meaning.
119 Pointed out by Karl Berry.
121 A more efficient version of factor, and possibly one that
122 accepts inputs of size 2^64 and larger.
124 dd: consider adding an option to suppress `bytes/block read/written'
125 output to stderr. Suggested here:

129 ------------------------
130 ls --color: Ed Avis' patch to suppress escape sequences for
131 non-highlighted files
133 getpwnam from Bruce Korb
135 pb (progress bar) from Miika Pekkarinen
137 ------------------------------
139 Have euidaccess.m4 check for eaccess as well as euidaccess
140 If found, then do `#define euidaccess eaccess'.
142 Remove long-deprecated options. Search case-insensitive for
143 `deprecated' and `remove in '. Automate this.
145 Add a distcheck-time test to ensure that every distributed
146 file is either read-only(indicating generated) or is
147 version-controlled and up to date.
149 Implement Ulrich Drepper's suggestion to use getgrouplist rather
150 than getugroups. This affects only `id', but makes a big difference
151 on systems with many users and/or groups, and makes id usable once
152 again on systems where access restrictions make getugroups fail.
153 But first we'll need a run-test (either in an autoconf macro or at
154 run time) to avoid the segfault bug in libc-2.3.2's getgrouplist.
155 In that case, we'd revert to using a new (to-be-written) getgrouplist
156 module that does most of what `id' already does. Or just avoid the
157 buggy use of getgrouplist by never passing it a buffer of length zero.
158 See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200327
160 remove `%s' notation:
161 grep -E "\`%.{,4}s'" src/*.c
163 remove or adjust chown's --changes option, since it
164 can't always do what it currently says it does.
166 Adapt tools like wc, tr, fmt, etc. (most of the textutils) to be
167 multibyte aware. The problem is that I want to avoid duplicating
168 significant blocks of logic, yet I also want to incur only minimal
169 (preferably `no') cost when operating in single-byte mode.
171 Remove all uses of the `register' keyword
173 pr's use of nstrftime can make it malloc a very large (up to SIZE_MAX) buffer
175 ls.c: use gettime rather than clock_gettime, gettimeofday, time
