1 restore djgpp, eventually
3 add unit tests for lib/*.c
5 strip: add an option to specify the program used to strip binaries.
6 suggestion from Karl Berry
9 Address this comment: FIXME: mv's behavior in this case is system-dependent
10 Better still: fix the code so it's *not* system-dependent.
12 implement --target-directory=DIR for install (per texinfo documentation)
14 ls: add --format=FORMAT option that controls how each line is printed.
16 cp --no-preserve=X should not attempt to preserve attribute X
17 reported by Andreas Schwab
19 copy.c: Address the FIXME-maybe comment in copy_internal.
20 And once that's done, add an exclusion so that `cp --link'
21 no longer incurs the overhead of saving src. dev/ino and dest. filename
24 See if we can be consistent about where --verbose sends its output:
25 These all send --verbose output to stdout:
26 head, tail, rm, cp, mv, ln, chmod, chown, chgrp, install, ln
27 These send it to stderr:
31 Write an autoconf test to work around build failure in HPUX's 64-bit mode.
32 See notes in README -- and remove them once there's a work-around.
34 Integrate use of sendfile, suggested here:
35 http://mail.gnu.org/archive/html/bug-fileutils/2003-03/msg00030.html
36 I don't plan to do that, since a few tests demonstrate no significant benefit.
38 Should printf '\0123' print "\n3"?

42 printf: consider adapting builtins/printf.def from bash
44 df: add `--total' option, suggested here http://bugs.debian.org/186007
46 seq: give better diagnostics for invalid formats:
47 e.g. no or too many % directives
48 seq: consider allowing format string to contain no %-directives
50 dd: consider adding an option to suppress `bytes/block read/written'
51 output to stderr. Suggested here:

54 m4: rename all macros that start with AC_ to start with another prefix
56 resolve RH report on cp -a forwarded by Tim Waugh
58 Martin Michlmayr's patch to provide ls with `--sort directory' option
60 tail: don't use xlseek; it *exits*.
61 Instead, maybe use a macro and return nonzero.
63 add mktemp? Suggested by Nelson Beebe
65 Now that AC_FUNC_LSTAT and AC_FUNC_STAT are in autoconf,
66 remove m4/stat.m4 and m4/lstat.m4.
68 df: alignment problem of `Used' heading with e.g., -mP
69 reported by Karl Berry
71 tr: support nontrivial equivalence classes, e.g. [=e=] with LC_COLLATE=fr_FR
73 fix tail -f to work with named pipes; reported by Ian D. Allen
74 $ mkfifo j; tail -f j & sleep 1; echo x > j
75 ./tail: j: file truncated
76 ./tail: j: cannot seek to offset 0: Illegal seek
78 lib/strftime.c: Since %N is the only format that we need but that
79 glibc's strftime doesn't support, consider using a wrapper that
80 would expand /%(-_)?\d*N/ to the desired string and then pass the
81 resulting string to glibc's strftime.
83 sort: Compress temporary files when doing large external sort/merges.
84 This improves performance when you can compress/uncompress faster than
85 you can read/write, which is common in these days of fast CPUs.
86 suggestion from Charles Randall on 2001-08-10
88 sort: Add an ordering option -R that causes 'sort' to sort according
89 to a random permutation of the correct sort order. Also, add an
90 option --random-seed=SEED that causes 'sort' to use an arbitrary
91 string SEED to select which permutations to use, in a deterministic
92 manner: that is, if you sort a permutation of the same input file
93 with the same --random-seed=SEED option twice, you'll get the same
94 output. The default SEED is chosen at random, and contains enough
95 information to ensure that the output permutation is random.
96 suggestion from Feth AREZKI, Stephan Kasal, and Paul Eggert on 2003-07-17
98 unexpand: [http://www.opengroup.org/onlinepubs/007908799/xcu/unexpand.html]
99 printf 'x\t \t y\n'|unexpand -t 8,9 should print its input, unmodified.
100 printf 'x\t \t y\n'|unexpand -t 5,8 should print "x\ty\n"
102 Let GNU su use the `wheel' group if appropriate.

105 sort: Investigate better sorting algorithms; see Knuth vol. 3.
107 We tried list merge sort, but it was about 50% slower than the
108 recursive algorithm currently used by sortlines, and it used more
109 comparisons. We're not sure why this was, as the theory suggests it
110 should do fewer comparisons, so perhaps this should be revisited.
111 List merge sort was implemented in the style of Knuth algorithm
112 5.2.4L, with the optimization suggested by exercise 5.2.4-22. The
113 test case was 140,213,394 bytes, 426,4424 lines, text taken from the
114 GCC 3.3 distribution, sort.c compiled with GCC 2.95.4 and running on
115 Debian 3.0r1 GNU/Linux, 2.4GHz Pentium 4, single pass with no
116 temporary files and plenty of RAM.
118 Since comparisons seem to be the bottleneck, perhaps the best
119 algorithm to try next should be merge insertion. See Knuth section
120 5.3.1, who credits Lester Ford, Jr. and Selmer Johnson, American
121 Mathematical Monthly 66 (1959), 387-389.
123 cp --recursive: perform dir traversals in source and dest hierarchy rather
124 than forming full file names. The latter (current) approach fails
125 unnecessarily when the names become very long.
127 tail --p is now ambiguous
129 Remove suspicious uses of alloca (ones that may allocate more than
132 Adapt these contribution guidelines for coreutils:
133 http://sources.redhat.com/automake/contribute.html
136 Changes expected to go in, post-5.2.1:
137 ======================================
139 wc: add an option, --files0-from [as for du] to make it read NUL-delimited
140 file name arguments from a file.
142 dd patch from Olivier Delhomme
144 Apply Andreas Gruenbacher's ACL and xattr changes
146 Apply Bruno Haible's hostname changes
148 stat: no longer output trailing newline for user-supplied FORMATs
149 This will mean adding \n to default formats, internally.
151 test/mv/*: clean up $other_partition_tmpdir in all cases
153 ls: when both -l and --dereference-command-line-symlink-to-dir are
154 specified, consider whether to let the latter select whether to
155 dereference command line symlinks to directories. Since -l has
156 an implicit --NO-dereference-command-line-symlink-to-dir meaning.
157 Pointed out by Karl Berry.
159 A more efficient version of factor, and possibly one that
160 accepts inputs of size 2^64 and larger.
162 Re-add a separate test for du's stack space usage (like the one removed
163 from tests/rm/deep-1).
