2015-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * tests/sample-test: Adjust to use the single most recent year. * tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message, so that year is updated automatically in future.
2014-09-19doc: output correct --help references with --program-prefixPádraig Brady
* src/system.h (emit_ancillary_info): Take the invariant PROGRAM_NAME as a parameter, so that consistent references are made to online docs and texinfo nodes, when a --program-prefix is in place. Note the man pages don't need this fix as they're generated before the program prefix is used. * NEWS: Mention the improvements in references to online documentation.

2014-01-02maint: update all copyright year number rangesBernhard Voelker
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2013-01-23maint: define usage note about mandatory args centrallyBernhard Voelker
Each program with at least one long option which is marked as 'required_argument' and which has also a short option for that option, should print a note about mandatory arguments. Define that well-known note centrally and use it rather than literal printf/fputs, and add it where it was missing. * src/system.h (emit_mandatory_arg_note): Add new function. * src/cp.c (usage): Use it rather than literal printf/fputs. * src/csplit.c, src/cut.c, src/date.c, src/df.c, src/du.c: * src/expand.c, src/fmt.c, src/fold.c, src/head.c, src/install.c: * src/kill.c, src/ln.c, src/ls.c, src/mkdir.c, src/mkfifo.c: * src/mknod.c, src/mv.c, src/nl.c, src/od.c, src/paste.c: * src/pr.c, src/ptx.c, src/shred.c, src/shuf.c, src/sort.c: * src/split.c, src/stdbuf.c, src/tac.c, src/tail.c, src/timeout.c: * src/touch.c, src/truncate.c, src/unexpand.c, src/uniq.c: Likewise. * src/base64.c (usage): Add call of the above new function because at least one long option has a required argument. * src/basename.c, src/chcon.c, src/date.c, src/env.c: * src/nice.c, src/runcon.c, src/seq.c, src/stat.c, src/stty.c: Likewise.

2011-07-20unexpand: fix misalignment when spaces span a tabstopPádraig Brady
The following dropped the space from the first field printf "1234567 \t1\n" | unexpand -a Note POSIX says that spaces should not precede tabs. Also a single trailing space should not be converted if the next field starts with non blank characters. So we enforce those rules too, with this change. * src/unexpand.c (unexpand): Implement as per POSIX rules. * tests/misc/unexpand: Add tests, and adjust existing tests as per POSIX rules. * NEWS: Mention the fix. Reported by Hallvard B Furuseth

2010-07-22provide POSIX_FADV_SEQUENTIAL hint to appropriate utilsPádraig Brady
Following on from commit dae35bac, 01-03-2010, "sort: inform the system about our input access pattern" apply the same hint to all appropriate utils. This currently gives around a 5% speedup for reading large files from fast flash devices on GNU/Linux. * src/base64.c: Call fadvise (..., FADVISE_SEQUENTIAL); * src/cat.c: Likewise. * src/cksum.c: Likewise. * src/comm.c: Likewise. * src/cut.c: Likewise. * src/expand.c: Likewise. * src/fmt.c: Likewise. * src/fold.c: Likewise. * src/join.c: Likewise. * src/md5sum.c: Likewise. * src/nl.c: Likewise. * src/paste.c: Likewise. * src/pr.c: Likewise. * src/ptx.c: Likewise. * src/shuf.c: Likewise. * src/sum.c: Likewise. * src/tee.c: Likewise. * src/tr.c: Likewise. * src/tsort.c: Likewise. * src/unexpand.c: Likewise. * src/uniq.c: Likewise. * src/wc.c: Likewise, unless we don't actually read().
2010-05-31maint: make spacing around "=" consistent, even in IF_LINTJim Meyering
E.g., - size_t desired_width IF_LINT (= 0); + size_t desired_width IF_LINT ( = 0); Use this command: g grep -l IF_LINT | grep '\.[ch]$' \ | xargs perl -pi -e 's/(IF_LINT \()= /$1 = /'
2010-05-31maint: replace each "for (;;)" with "while (true)"Jim Meyering
Run this command: git ls-files | grep '\.[ch]$' \ | xargs perl -pi -e 's/for \(;;\)/while (true)/g' ...except for randint.c, which does not include stdbool.h. In that case, use "while (1)". * gl/lib/randint.c (randint_genmax): Use "while (1)" for infloops. * src/cat.c (simple_cat, cat): Use "while (true)" for infloops. * gl/lib/randread.c (readsource, readisaac): Likewise. * src/copy.c (copy_reg): Likewise. * src/csplit.c (record_line_starts, process_regexp): Likewise. * src/cut.c (set_fields): Likewise. * src/dd.c (iread, parse_symbols): Likewise. * src/df.c (find_mount_point, main): Likewise. * src/du.c (main): Likewise. * src/expand.c (expand): Likewise. * src/factor.c (factor_using_division, do_stdin): Likewise. * src/fmt.c (get_space): Likewise. * src/ls.c (decode_switches): Likewise. * src/od.c (main): Likewise. * src/pr.c (main, read_line): Likewise. * src/shred.c (dopass, genpattern): Likewise. * src/sort.c (initbuf, fillbuf, getmonth, keycompare): Likewise. * src/split.c (bytes_split, lines_split): Likewise. * src/tac.c (tac_seekable): Likewise. * src/test.c (and, or): Likewise. * src/tr.c (squeeze_filter, main): Likewise. * src/tsort.c (search_item): Likewise. * src/unexpand.c (unexpand): Likewise. * src/uniq.c (main): Likewise. * src/yes.c (main): Likewise.

2009-09-23maint: Use logical rather than bitwise operators on boolsPádraig Brady
This is because bitwise operators are: - confusing and inconsistent in a boolean context - non short circuiting - brittle in C89 where bool can be an int (so > 1)
2009-09-21doc: mention the texinfo documentation in --helpPádraig Brady
* src/system.h: Rename emit_bug_reporting_address() to emit_ancillary_info() and update it to not print the translation project address in en_* locales, and _do_ print it in the 'C' (and other) locales so that it's included in the default man page. Also mention how to invoke the texinfo documentation for each command. Also move the "hard-locale.h" include to the 8 files that now use it. * man/help2man: Strip the newly added texinfo reference from the --help output as a more verbose version is already added by help2man. Suggestion from C de-Avillez

Follow POSIX's rules about -a requiring two blanks before a tab stop. Get rid of internal label and goto.
2004-08-03Int cleanup and minor reorganization to be more like src/expand.c.Paul Eggert
Include quote.h, xstrndup.h. (TAB_STOP_SENTINEL): Increase from INT_MAX to INTMAX_MAX. (convert_entire_line, have_read_stdin, parse_tabstops, next_file, unexpand, main): Use bool for booleans. (tab_size, tab_list, add_tabstop, validate_tabstops, unexpand): Use uintmax_t for column counts. (first_free_tab, validate_tabstops, unexpand): Use size_t for sizes. (add_tabstop, parse_tabstops, main): Don't reserve UINTMAX_MAX as a tab stop. (parse_tabstops): Don't use ISBLANK on possibly-signed char. Detect overflow in tab stop string. (next_file, main): Use EXIT_FAILURE/EXIT_SUCCESS instead of 1/0. (unexpand): Concatenate input files the same way expand does.
2004-01-21(usage): Use EXIT_SUCCESS, not 0, for clarity.Jim Meyering
(usage): Don't bother normalizing exit status since the arg is already the correct exit status now.
2004-01-04(n_tabs_allocated): New global.Jim Meyering
(add_tabstop): Use x2nrealloc rather than xrealloc.
