Run "make update-copyright".

coreutils: keep lines within 80-column limits

2010-12-28T20:30:42Z

* cfg.mk (LINE_LEN_MAX, FILTER_LONG_LINES): New macros. (sc_long_lines): New rule. * HACKING: Use shorter URLs to the same material. * doc/Makefile.am, doc/coreutils.texi, m4/boottime.m4: * man/help2man, man/stdbuf.x, src/Makefile.am, src/cat.c, src/copy.c: * src/cp.c, src/dd.c, src/df.c, src/du.c, src/groups.c, src/install.c: * src/ls.c, src/md5sum.c, src/mv.c, src/od.c, src/pinky.c, src/ptx.c: * src/readlink.c, src/remove.c, src/rmdir.c, src/setuidgid.c: * src/sort.c, src/tail.c, src/touch.c, tests/Coreutils.pm: * tests/cp/existing-perm-race, tests/cp/perm, tests/cp/preserve-gid: * tests/du/2g, tests/du/long-from-unreadable, tests/init.sh: * tests/install/basic-1, tests/ls/nameless-uid: * tests/ls/readdir-mountpoint-inode, tests/misc/chroot-credentials: * tests/misc/cut, tests/misc/date, tests/misc/join, tests/misc/md5sum: * tests/misc/sha1sum, tests/misc/sha224sum, tests/misc/sort: * tests/misc/sort-continue, tests/misc/sort-files0-from: * tests/misc/sort-rand, tests/misc/stdbuf, tests/misc/tr: * tests/misc/uniq, tests/mv/atomic, tests/mv/part-fail: * tests/mv/part-symlink, tests/mv/sticky-to-xpart, tests/pr/pr-tests: * tests/rm/fail-2eperm, tests/rm/interactive-always: Reformat to fit within 80 columns. * doc/Makefile.am (BAD_POSIX_PERL): New macro. * doc/coreutils.texi: Reword slightly, to make menus and index lines shorter. * src/md5sum.c: Redo --help output so that it fits within 79 columns, since that's a bit more portable and all the other --help strings fit in 79 columns.

fadvise: new module providing a simpler interface to posix_fadvise

2010-07-22T00:03:48Z

* bootstrap.conf: Include the new module * gl/lib/fadvise.c: Provide a simpler interface to posix_fadvise. (fadvise): Provide hint to the whole file associated with a stream. (fdadvise): Provide hint to the specific portion of a file associated with a file descriptor. * gl/lib/fadvise.h: Redefine POSIX_FADV_* to FADVISE_* enums. * gl/modules/fadvise: New file. * m4/jm-macros.m4: Remove the no longer needed posix_fadvise check. * .x-sc_program_name: Exclude test-fadvise.c from this check. * gl/tests/test-fadvise (main): New test program. * gl/modules/fadvise-testss: A new index to reference the tests. * src/sort.c (stream_open): Use the new interface. * src/dd.c (iwrite): Likewise.

dd: also spell out size on memory exhaustion

2010-07-13T00:13:13Z

* src/dd.c (dd_copy): Use requested blocksize (not adjusted) in diagnostic, to forestall user complaints that the numbers don't match exactly. Report both exact and human-readable sizes, using a message format that is consistent with both "BBBB bytes (N XB) copied" in dd.c and "memory exhausted" in lib/xmalloc.c.

dd: print a better diagnostic for an invalid block size

2010-06-14T20:34:42Z

* src/dd.c (dd_copy): Give a better diagnostic than "dd: memory exhausted" for an over-large bs= block size setting. Same for ibs= and obs=. Reported by Imre Péntek in http://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/591969

maint: replace each "for (;;)" with "while (true)"

2010-05-31T09:02:21Z

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.

maint: remove now-redundant definitions provided by signal.h

2010-05-03T10:26:20Z

* src/dd.c (SA_NODEFER, SA_RESETHAND): Remove definitions, now that gnulib guarantees they are defined in . * src/ls.c (SA_RESTART): Likewise.

maint: add a space before open-paren, where lacking

2010-03-17T17:28:28Z

* src/copy.c (copy_reg): Likewise. * src/cut.c (main): Likewise. * src/dd.c (main): Likewise. * src/getlimits.c (print_int): Likewise. * src/join.c (join): Likewise. * src/pwd.c (logical_getcwd): Likewise. * src/sort.c (specify_nmerge, mergefps, avoid_trashing_input): Likewise. (merge): Likewise. * src/uptime.c (usage): Likewise.

2010-01-01T13:06:47Z

Use this command: git ls-files | grep -v COPYING \ | xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \ build-aux/update-copyright

maint: Use logical rather than bitwise operators on bools

2009-09-23T13:33:40Z

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)
