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

108 Changes expected to go in, someday.
109 ======================================
111 dd patch from Olivier Delhomme
113 Andreas Gruenbacher's xattr changes
115 Apply Bruno Haible's hostname changes
117 test/mv/*: clean up $other_partition_tmpdir in all cases
119 ls: when both -l and --dereference-command-line-symlink-to-dir are
120 specified, consider whether to let the latter select whether to
121 dereference command line symlinks to directories. Since -l has
122 an implicit --NO-dereference-command-line-symlink-to-dir meaning.
123 Pointed out by Karl Berry.
125 A more efficient version of factor, and possibly one that
126 accepts inputs of size 2^64 and larger.
128 dd: consider adding an option to suppress `bytes/block read/written'
129 output to stderr. Suggested here:
130 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=165045
132 Pending copyright papers:
133 ------------------------
134 ls --color: Ed Avis' patch to suppress escape sequences for
135 non-highlighted files
137 getpwnam from Bruce Korb
139 pb (progress bar) from Miika Pekkarinen
141 ------------------------------
143 Have euidaccess.m4 check for eaccess as well as euidaccess
144 If found, then do `#define euidaccess eaccess'.
146 Remove long-deprecated options. Search case-insensitive for
147 `deprecated' and `remove in '. Automate this.
149 Add a distcheck-time test to ensure that every distributed
150 file is either read-only(indicating generated) or is
151 version-controlled and up to date.
153 Implement Ulrich Drepper's suggestion to use getgrouplist rather
154 than getugroups. This affects only `id', but makes a big difference
155 on systems with many users and/or groups, and makes id usable once
156 again on systems where access restrictions make getugroups fail.
157 But first we'll need a run-test (either in an autoconf macro or at
158 run time) to avoid the segfault bug in libc-2.3.2's getgrouplist.
159 In that case, we'd revert to using a new (to-be-written) getgrouplist
160 module that does most of what `id' already does. Or just avoid the
161 buggy use of getgrouplist by never passing it a buffer of length zero.
162 See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200327
164 remove `%s' notation:
165 grep -E "\`%.{,4}s'" src/*.c
167 remove or adjust chown's --changes option, since it
168 can't always do what it currently says it does.
170 Adapt tools like wc, tr, fmt, etc. (most of the textutils) to be
171 multibyte aware. The problem is that I want to avoid duplicating
172 significant blocks of logic, yet I also want to incur only minimal
173 (preferably `no') cost when operating in single-byte mode.
175 Remove all uses of the `register' keyword
177 pr's use of nstrftime can make it malloc a very large (up to SIZE_MAX) buffer
179 ls.c: use gettime rather than clock_gettime, gettimeofday, time
