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.

maint: update all FSF copyright year lists to include 2010

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)

doc: mention the texinfo documentation in --help

2009-09-21T11:37:57Z

* 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

dd conv=unblock: print final newline consistently

2009-09-10T10:25:04Z

* src/dd.c (dd_copy) [C_UNBLOCK]: Always print the final newline for non-empty output, not just when output size is a multiple of cbs. * doc/coreutils.texi (dd invocation) [conv=unblock]: Mention that dd prints a newline after each output record, not just when replacing trailing spaces. Reported by Ulrich Drepper. * tests/dd/unblock: New file. Test for this. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it.
