[platform/upstream/coreutils.git] / ChangeLog

2005-06-14  William Brendling  <wbrendling@gmail.com>

        * src/du.c: Add --last-time and --time-style options.

2005-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        * Version 5.3.1.

        * tests/umask-check: New file.
        * tests/Makefile.am (EXTRA_DIST): Add umask-check.
        * tests/mkdir/perm: Use umask-check.
        * tests/cp/cp-parents: Likewise, instead of using chmod
        as described below.  Problem reported by Kevin Mudrick.

2005-06-22  Jim Meyering  <jim@meyering.net>

        Make rmdir produce diagnostics like this:
        rmdir: /tmp: Permission denied
        not like this:
        rmdir: `/tmp': Permission denied

        * src/rmdir.c: Include "quotearg.h", not "quote.h".
        (remove_parents, main): Use quotearg_colon, not quote.

2005-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        * tests/cp/cp-parents: Use chmod to work around some hosts with
        ACL problems.  Problem reported by Kevin Mudrick.

2005-06-21  Jim Meyering  <jim@meyering.net>

        * tests/du/deref-args: Use --apparent-size to avoid the vagaries
        of counting blocks.  Kevin Mudrick reported that this test would
        fail on an nfs-mounted directory where attribute-caching is
        turned on.

2005-06-19  Jim Meyering  <jim@meyering.net>

        * src/tac.c (tac_mem, tac_stdin_to_mem): Remove #if-0'd functions.

        * src/shred.c (usage): Use `file system', not `filesystem'.

2005-06-18  Jim Meyering  <jim@meyering.net>

        * src/tr.c (unquote): Remove unnecessary `' quotes from a diagnostic.

2005-06-17  Jim Meyering  <jim@meyering.net>

        * src/shred.c (usage): Clarify that shred works on an ext3 file
        system as long as it's not in data=journal mode.
        Tiny change by Mark Melahn.

2005-06-16  Paul Eggert  <eggert@cs.ucla.edu>

        * src/hostid.c (main): Don't print fewer than 8 digits, or spurious
        leading "f"s.  "f" problem reported by Tim Waugh.
        * NEWS: Document this.

2005-06-16  Jim Meyering  <jim@meyering.net>

        Don't embed `this'-style quotes in format strings.
        * src/tr.c: Rather than this: error (..., "...`%s'...", arg);
        do this:                      error (..., "...%s...", quote (arg));
        * src/od.c, src/tr.c, src/csplit.c, src/date.c, src/hostname.c:
        * src/join.c, src/ptx.c, src/seq.c, src/sort.c, src/split.c:
        * src/split.c, src/tail.c: Likewise.

        * src/sleep.c: Include "quote.h".  Remove hard-coded quotes, as above.
        * src/nice.c, src/printf.c, src/fold.c, src/pr.c: Likewise.
        * src/factor.c, src/cat.c, src/expr.c, src/stty.c: Likewise.

        * src/mv.c: Finally remove support for --version-control=S (-V).
        It was deprecated nearly 6 years ago and has been warning
        users to switch to --backup=S since fileutils-4.0j.
        * src/cp.c, src/install.c, src/ln.c: Likewise.

2005-06-15  Jim Meyering  <jim@meyering.net>

        * src/install.c (main): Fix my typo: s/argv[optind]/file[i]/.
        * tests/install/basic-1: Ensure that each `-d'-specified directory
        is created.  Ensure that rel-named dirs are not created when
        chdir($PWD) fails.

        * tests/mkdir/p-3: Add a test for just-fixed bug in mkdir-p.c.

2005-06-14  Paul Eggert  <eggert@cs.ucla.edu>

        Improve diagnostics for restore_cwd failure.
        * src/install.c (main): Standardize on a diagnostic for
        restore_cwd failure, and report errno.
        (install_file_in_file_parents): Fail if restore_cwd fails and
        one of the files is relative.  This fixes a bug (albeit unlikely).
        * src/mkdir.c (create_parents): Remove static var (now local to 'main').
        (main): Standardize on a diagnostic for restore_cwd failure,
        and report errno.
        Don't bother to check cwd_errno unless create_parents.
        Use mkdir rather than make_dir; it's simpler.

        * src/install.c (main): Adjust to new make_dir_parents convention.
        * src/mkdir.c (main): Likewise.

2005-06-14  Jim Meyering  <jim@meyering.net>

        * tests/mkdir/p-3: Ensure mkdir succeeds if the following argument
        is an absolute directory name.

        * Makefile.maint (my-distcheck): Add -Wall to the list of options that
        are used with -Werror.  This target is not intended for general use.

2005-06-13  Jim Meyering  <jim@meyering.net>

        * src/mkdir.c (main): Give a diagnostic for -- and skip -- each
        relative directory name after make_dir_parents fails to restore
        the working directory.  Before, `mkdir -p' could create directories
        in the wrong place in unusual circumstances.
        * src/install.c (main): Likewise.
        (install_file_in_file_parents): Update make_dir_parents caller.
        * tests/mkdir/p-3: New test for today's mkdir.c/mkdir-p.c bug fixes.
        * tests/mkdir/Makefile.am (TESTS): Add p-3.

2005-06-10  Paul Eggert  <eggert@cs.ucla.edu>

        Act on the Austin Group's response yesterday to XCU ERN 63; see
        <http://www.opengroup.org/austin/docs/austin_260.txt>.

        * doc/coreutils.texi: Remove the extra spaces in "ls -l" output.
        * src/ls.c (any_has_acl): New var.
        (clear_files): Clear it.
        (gobble_file): Set it if a file has an ACL.
        (print_long_format): Omit needless space unless some file has an ACL.

2005-06-10  Jim Meyering  <jim@meyering.net>

        * src/system.h (VERIFY_W_TYPEOF): Add parentheses.

2005-06-02  Jim Meyering  <jim@meyering.net>

        * src/sort.c (usage): Put `Ordering options:' line where it belongs.

2005-06-01  Paul Eggert  <eggert@cs.ucla.edu>

        Use "file name" when talking about file names, instead of "filename"
        or "path", as per the GNU coding standards.
        * src/basename.c: Don't use "path" or "filename".
        * src/copy.c: Likewise.
        * src/copy.h: Likewise.
        * src/cp-hash.c: Likewise.
        * src/cp.c: Likewise.
        * src/df.c: Likewise.

2005-05-31  Jim Meyering  <jim@meyering.net>

        * src/copy.c (chown_privileges, chown_failure_ok): Mark as `extern'.
        This is a crutch so that `make distcheck's sc_tight_scope rule
        knows that they really are deliberately declared that way.

2005-05-30  Paul Eggert  <eggert@cs.ucla.edu>

        Port to Solaris 10's rules for whether programs can chown files.
        * src/copy.c [HAVE_PRIV_H]: Include <priv.h>.
        (DO_CHOWN): Remove.  Replaced by chown_failure_ok.  All callers
        changed.
        (copy_internal): If chown failed, don't worry about what happened
        to the mode bits; they can't have changed.
        (chown_privileges, chown_failure_ok): New functions.
        * src/copy.h: Add copyright notice.
        (struct cp_options): Remove myeuid member.  Add chown_privileges
        member.
        (chown_privileges, chown_failure_ok): New function decls.
        * src/cp.c (re_protect): Remove unnecessary call to geteuid.
        Use chown_failure_ok rather than our own code.
        * src/cp.c (cp_options_init): Use chown_privileges rather than geteuid.
        * src/install.c (cp_option_init): Likewise.
        * src/mv.c (cp_option_init): Likewise.

2005-05-29  Paul Eggert  <eggert@cs.ucla.edu>

        * src/chgrp.c (getgrnam) [!defined _POSIX_VERSION]: Remove decl.
        * src/chown-core.c (getgrnam, getgrgid) [!defined _POSIX_VERSION]:
        Remove decls.
        * src/cp.c (geteuid) [!defined _POSIX_VERSION]: Remove decl.

        [!defined _POSIX_VERSION]: Remove decls.
        * src/install.c (getpwnam, getgrnam): Remove decl.
        (getuid, getgid) [!defined _POSIX_VERSION]: Remove decls.
        * src/md5sum.c (OPENOPTS, TEXT1T01, TEXTCNVT): Remove.
        (digest_file): Use O_BINARY-using expr instead of OPENOPTS.
        * src/system.h: Don't bother mentioning _POSIX_VERSION in comment.
        * src/test.c: Include sys/param.h if it exists, not if _POSIX_VERSION
        isn't defined.
        Don't include <sys/file.h>; no longer needed.
        (getegid, geteuid): Remove no-longer-necessary decls.

        * src/pathchk.c (_POSIX_PATH_MAX) [!defined _POSIX_PATH_MAX]:
        Define to 256, not 255, as per modern POSIX.

2005-05-27  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: dd seek=N now conforms to POSIX if the output isn't seekable.
        * src/dd.c (skip): Return the number of records that were not
        skipped due to encountering EOF.
        (dd_copy): If the file wasn't seekable and EOF was encountered,
        write zeros past EOF until the desired offset is reached.

        * NEWS: expr and test now correctly compare integers of unlimited size.
        (Also, correct a comment that claimed that expr detects integer
        overflow; it does so only when converting from strings.)
        * src/expr.c: Include strnumcmp.h, xstrtol.h.
        (looks_like_integer): New function.
        (toarith): Use it.  Also, use xstrtoimax rather than rolling our
        own diagnostics.
        (eval2): Don't look for trouble if !evaluate; this simplifies things.
        Compare numbers using string comparison, so that overflow is
        not possible.
        * src/sort.c: Refactor so that others can use large-integer
        comparison functions.
        Include "strnumcmp.h".
        (NEGATION_SIGN, NUMERIC_ZERO, fraccompare):
        Remove; moved to strnumcmp.
        (decimal_point): Now int, to simplify converison overhead with
        new API.  All uses changed.
        (thousands_sep): Now -1 if there isn't one, as per new API.
        All uses changed.
        (numcompare): Move contents to strnumcmp module, except for
        skipping blanks.
        * src/test.c: Include inttostr.h, strnumcmp.h.
        (whitespace, digit, digit_value, integer_expected_error): Remove.
        (is_int): Remove; replaced by...
        (find_int): New function.
        (binary_operator): Don't let integers overflow in comparisons;
        return the correct answer instead.  Simplify the code.
        (unary_operator): Convert the integer ourself, since find_int
        no longer does so.
        * tests/expr/basic (bigcmp): New test.
        * tests/test/Test.pm (eq-6, gt-5, lt-5): New tests.

2005-05-26  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: nohup now redirects a tty stdin to an unreadable fd
        instead of closing it.
        * doc/coreutils.texi (nohup invocation): Document this.
        * src/nohup.c (main): Implement this.

2005-05-26  Jim Meyering  <jim@meyering.net>

        * src/expr.c (toarith): Fix a sign error introduced on 2005-01-14.
        Reported by David Alan Gilbert.
        * tests/expr/basic: Add tests using arithmetic on negative integers.

2005-05-19  Jim Meyering  <jim@meyering.net>

        * src/remove.c (AD_mark_helper, AD_mark_current_as_unremovable):
        Remove inaccurate-but-harmless `const' attributes.

        * src/join.c (decode_field_spec): Add an abort after
        `error (EXIT_FAILURE, ...' to avoid a gcc warning in caller,
        about variables being used uninitialized.

2005-05-18  Paul Eggert  <eggert@cs.ucla.edu>

        * configure.ac: Add copyright notice.  gl_LIB_CHECK -> cu_LIB_CHECK.
        * src/Makefile.am: Add copyright notice.
        (factor_LDADD): Remove, as factor no longer needs sqrt.
        * src/hostname.c: Remove test for HAVE_LIMITS_H; we can assume
        it's always true now.

2005-05-16  Paul Eggert  <eggert@cs.ucla.edu>

        Fix Cygwin porting problem reported by Eric Blake.
        * src/remove.c (DT_IS_DIR): Remove.
        (DT_IS_KNOWN, DT_MUST_BE): New macros.
        (remove_entry): Use them.

2005-05-14  Paul Eggert  <eggert@cs.ucla.edu>

        * src/remove.c: Include unlinkdir.h.
        (UNLINK_CAN_UNLINK_DIRS): Remove.
        (remove_entry): Use cannot_unlink_dirs () rather than
        UNLINK_CAN_UNLINK_DIRS.

2005-05-14  Jim Meyering  <jim@meyering.net>

        Update FSF postal mail address.

2005-05-13  Jim Meyering  <jim@meyering.net>

        * NEWS: `rm -r' now removes all of the files it should, even on
        systems with a buggy readdir affecting file systems inaccessible
        at configure time.

        In some unusual circumstances `rm -r' would fail to remove --
        or even consider -- all entries in a directory with more than 254
        (SunOS) or 338 (Darwin) entries.  This could cause trouble even on
        other types of systems when using an affected file system via e.g.,
        NFS.  The underlying cause was a bug in readdir on those systems.
        Coreutils-5.2.1 and earlier used a configure-time test designed
        to detect precisely those problem systems, but it would detect
        the problem and enable remove.c's work-around code only when its
        configure-time test was run on a losing file system.  Obviously,
        it couldn't detect a problem if the offending file system wasn't
        tested or even mounted at coreutils configure time.  Now, rm itself
        performs a minimal-cost run-time test to detect the problem.

        * src/remove.c (CONSECUTIVE_READDIR_UNLINK_THRESHOLD): Define.
        (remove_cwd_entries):  When readdir returns NULL for a directory from
        which we've removed more than CONSECUTIVE_READDIR_UNLINK_THRESHOLD
        entries, call rewinddir and then resume the readdir/unlink loop.
        (UNLINK_CAN_UNLINK_DIRS): Rename from ROOT_CAN_UNLINK_DIRS.

2005-05-12  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: nohup now closes stdin if it is a terminal, unless
        POSIXLY_CORRECT is set.  This fixes a glitch noted by Wayne Pollock in
        <https://www.opengroup.org/sophocles/show_mail.tpl?
        source=L&listname=austin-group-l&id=8341>.
        * doc/coreutils.texi (nohup invocation): Document this.
        * src/nohup.c (main): Implement this.

2005-05-12  Jim Meyering  <jim@meyering.net>

        * src/date.c: Assume `free (NULL)' works.
        * src/dd.c: Likewise.
        * src/df.c:Likewise.
        * src/dircolors.c:Likewise.

        * src/sort.c: Likewise.

2005-05-10  Jim Meyering  <jim@meyering.net>

        * tests/touch/not-owner: Skip this test if the user running it
        owns `/' or has write access to it.

        * src/copy.c (abandon_move): Remove erroneous UNWRITABLE check.
        This makes `mv -i --reply=no f1 f2' work as expected (in not
        performing the move operation).  But note that specifying `-i'
        after `--reply=no' does *not* work.
        Tiny patch from Vlada Macek.
        Correct a comment.
        * tests/mv/reply-no: New file.  Test for the above fix.
        * tests/mv/Makefile.am (TESTS): Add reply-no.

        * tests/ls-2/tests: Don't print PATH to stderr.

2005-05-08  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: cp, ln, mv, rm no longer discard white space when intepreting

2005-05-04  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: chmod -w now complains if it differs from chmod a-w.
        * src/chmod.c: Include quotearg.h.
        (diagnose_surprises): New var.
        (process_file): Diagnose surprises.  Simplify the logic a bit,
        while we're at it.

        * tests/chmod/umask-x: New file.

2005-05-02  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: ls --indicator-style=directory renamed to ls
        --indicator-style=slash, to avoid confusion with ls --directory.
        * src/ls.c (usage): Likewise.
        (slash): Renamed from directory_only.  All uses changed.

2005-05-01  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: "chmod +1 foo" is now diagnosed.

2005-04-29  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: ls -p now marks only directories.  New option
        --indicator-style=directory equivalent to -p.
        * doc/coreutils.texi (ls invocation): Document this.
        Also, mention ">" is for doors.
        * src/ls.c (enum indicator_style): New constant directory_only,
        for -p.
        (indicator_style_args, indicator_style_types): Set it appropriately.
        (decode_switches, gobble_file, print_type_indicator):
        (length_of_file_name_and_frills):
        Implement the change described in NEWS.
        (decode_switches): Quote ">", too.
        (usage): Update to match the new behavior.  Describe ">".
        * tests/ls/file-type: Test for new behavior.  Omit -1 option.
        The "ls --color" test wasn't being checked; add a check for
        "ls --color=auto" instead.

        * tests/head/Test.pm: Don't set _POSIX2_VERSION; no longer needed.
        * tests/misc/split-fail: Likewise.
        * tests/pr/Test.pm: Likewise.
        * tests/sort/Test.pm: Fix comment to match new behavior of "sort".

        The following was partly derived from a tiny change by Eric Blake:
        * tests/misc/nice: Don't use 'set -'.  It's not portable to strict
        POSIX 1003.1-2001 hosts.  Also, don't set _POSIX2_VERSION.

        * tests/stty/row-col-1: Don't use 'set -'.

2005-04-26  Paul Eggert  <eggert@cs.ucla.edu>

        Restore support for usages like "head -1" and "tail -1",
        even when conforming to POSIX 1003.1-2001.
        Fix bug with "POSIXLY_CORRECT=1 fold file -3".
        join now supports a NUL field separator, e.g., "join -t '\0'".
        join now detects and reports incompatible options, e.g.,
        "join -t x -t y",
        * NEWS: Document this.
        * src/date.c: Remove posixver.h and its uses.
        (COMMON_SHORT_OPTIONS): Remove.
        (short_options): New constant.
        (short_options, usage): -I now always takes an optional arg.
        * src/expand.c: Remove posixver.h and its uses.
        (shortopts): New constant.  -DIGIT now always takes an optional arg.
        (main): Revamp parsing of -DIGIT to let parse_tab_stops handle it.
        Don't complain about -DIGIT.
        * src/fold.c: Remove posixver.h and its uses.
        (shortopts): New constant.  -DIGIT now always takes an optional arg.

        similar to expand.
        * src/head.c: Remove posixver.h and its uses.
        (header_mode_option): Remove.
        (main): Don't complain about obsolete -NUM args.
        * src/join.c: Remove posixver.h and its uses.
        (obsolete_usage): Remove.
        (join_field_1, join_field_2): Initialize to SIZE_MAX to indicate
        they haven't been set yet.
        (tab): Now int, not char.  Initialize to -1 to indicate white space
        separates columns, so that we can use NUL as a separator.
        All uses changed.
        (OBSOLETE_LONG_OPTIONS, get_option): Remove.
        (string_to_join_field): Remove ERR_MSG_FMT arg; a single format
        suffices.  Use xstrtoul for sizes; it suffices.
        (decode_field_spec): Report an error and exit on failure.  Return void,
        not bool.
        (add_field_list): Likewise.
        (set_join_field): New function.
        (enum operand_status): New enum.
        (add_file_name): New args OPERAND_STATUS, JOPTION_COUNT,
        PREV_OPTC_STATUS, OPTC_STATUS to handle the bewildering array of
        possibilities with obsolete option parsing.
        (main): Use it.  Do not depend on POSIX version.
        Check for conflicting options.  Parse obsolete options -j1 and -j2
        so that it is a pure extension to POSIX 1003.1-2001.
        Allow '-t\0' to specify a NUL tab, stealing the code from 'sort'.
        * src/nice.c: Remove posixver.h and its uses.
        (main): Always support -NUM option.
        * src/od.c: Remove posixver.h and its uses.

        (COMMON_SHORT_OPTIONS): Remove.
        (main): Redo workaround for Solaris compatibility with -y.
        This change isn't visible to the user; it just cleans up the
        code so that we don't need posixver.h.
        * src/split.c: Remove posixver.h and its uses.
        (main): Don't complain about -NUM option.
        * src/tail.c (parse_obsolete_option): Don't complain about -NUM.

        * src/nohup.c (main): If getopt fails, exit with status 127,
        not status 1.  POSIX requires this.
        * NEWS: Document this.

        * src/nice.c (main): Report proper program name when getopt finds
        trouble.  Problem reported by Behdad Esfahbod.

        * NEWS: Fix bug with "mkdir -m =+x dir"; the umask was being ignored
        when the "+x" was being evaluated.
        * mkdir.c (main): Compile mode with MODE_MASK_ALL and initial umask.
        * mkfifo.c (main): Likewise.

2005-04-20  Paul Eggert  <eggert@cs.ucla.edu>

        Port test cases to Microsoft-Windows-related environments,
        following suggestions from Eric Blake.
        * tests/install/Makefile.am (TESTS_ENVIRONMENT): Add EXEEXT.
        * tests/install/basic-1: Undo previous change.
        (dd, dd2): New vars, which use $EXEEXT.  All uses of dd and dd2 changed.
        * tests/install/trap: Undo previous change.
        (sig): New var.  Use it insted of "trap '' CHLD".
        Append $EXEEXT to executable name.

        "fetish" -> "coreutils" in more places.
        * tests/Coreutils.pm: Renamed from tests/Fetish.pm.
        (package Coreutils): Renamed from package Fetish.  All uses changed.
        * tests/Makefile.am (EXTRA_DIST): Add Coreutils.pm and
        remove Fetish.pm.

2005-04-19  Paul Eggert  <eggert@cs.ucla.edu>

        * tests/mv/setup (dot_mount_point): Use stat -L, in case the
        directory is actually a symbolic link.  Problem reported by
        Eric Blake.

        * tests/mv/mv-special-1: Use test -p to test for fifos, rather
        than the (incorrect) test -f and the (inadequate) ls.  ls is
        inadequate because on some hosts a buggy mv will create a file of
        the wrong type (problem reported by Eric Blake).  Skip this test
        if test -p doesn't work.

        * tests/chmod/setgid: Use numeric group ids, not symbolic group names,
        since the latter can have shell metacharacters in them (e.g., spaces).
        This follows up to the 2005-01-17 patch, which missed this occurrence.

2005-04-18  Paul Eggert  <eggert@cs.ucla.edu>

        "fetish" -> "coreutils" in several places.
        * Makefile.cfg (ftp): Remove fetish.sf.net.
        * Makefile.maint (emit_upload_commands): Likewise.
        * src/Makefile.am (LDADD, $(PROGRAMS)): fetish -> coreutils.

        * tests/chmod/setgid (FETISH_GROUP): Renamed from COREUTILS_GROUP.

        * tests/install/basic-1: Use "cat", not "test", to test for
        ../../src/dd.  Problem reported by Eric Blake.

2005-04-18  Jim Meyering  <jim@meyering.net>

        * src/dd.c: Don't include stat-macros.h directly.  system.h does that.

2005-04-17  Paul Eggert  <eggert@cs.ucla.edu>

        Work around a couple of "make check" failures reported for Cygwin
        and ash by Eric Blake.
        * tests/install/basic-1: Skip this test if ../../src/dd isn't readable.
        * tests/install/trap: Skip this test if "trap '' CHLD" doesn't work.

2005-04-16  Jim Meyering  <jim@meyering.net>

        * src/dd.c (S_TYPEISSHM): Remove definition.
        Get the definition by including "stat-macros.h", instead.

2005-04-14  Paul Eggert  <eggert@cs.ucla.edu>

        Fix test suite problems reported by Eric Blake on Cygwin.
        * tests/mv/mv-special-1: Ignore chatter about when files are removed,
        since POSIX doesn't require rename to fail across file systems.
        * tests/mv/setup (dot_mount_point): Use stat rather than df, as
        it's more reliable.
        (other_partition_tmpdir): Remove df from name as that would be
        misleading now.

2005-04-14  Jim Meyering  <jim@meyering.net>

        * src/chown-core.c: Correct typo, fchmod -> fchown, in a comment.

2005-04-12  Paul Eggert  <eggert@cs.ucla.edu>

        * src/ls.c (usage): "uid" -> "user ID".

2005-04-12  Jim Meyering  <jim@meyering.net>

        * src/tsort.c (tsort): Use "%s" as the format string,
        rather than a diagnostic or a file name.

        * src/comm.c (compare_files): Remove declaration of unused local.

        * src/chown-core.c (chopt_free): Mark parameter as unused.

2005-04-11  Paul Eggert  <eggert@cs.ucla.edu>

        * man/chown.x: Reword to match user manual.
        * man/id.x: Likewise.
        * src/setuidgid.c (usage): Use "user ID", not "UID", and similarly
        for "group ID".
        * src/whoami.c (usage, main): Likewise.

        Add bulletproofing for cases where stdin, stdout, or stderr are closed.
        * src/comm.c: Include stdio-safer.h.
        (compare_files): Exit right away on I/O error rather than continuing
        and producing confusing output and error messages.
        Return void, not int; all callers changed.
        Use fopen_safer to avoid confusion with file descriptors.
        * src/copy.c: Include unistd-safer.h.
        (copy_reg): Use fd_safer.
        * src/csplit.c: Include stdio-safer.h.
        (input_desc): Remove unnecessary static initialization.
        (set_input_file): Use STDIN_FILENO, not 0.

        * src/dircolors.c (dc_parse_file): Don't assume fopen does not
        return stdin.
        * src/head.c (head_file): Don't assume open does not return 0.
        * src/join.c: Include stdio-safer.h.
        (main): Use fopen_safer.  Simplify the resulting code.
        * src/md5sum.c (digest_file, digest_check):
        Don't assume that fopen does not return stdin.

        stdout.  Use freopen instead.
        * src/shred.c: Include unistd-safer.h.
        (wipename): Use fd_safer on directory file descriptor.
        (wipefile): Remove special case for /dev/fd/* on older hosts.
        It didn't work in general, and wasn't documented.
        Use fd_safer.
        * src/sort.c: Include unistd-safer.h.
        (create_temp_file): Use fd_safer.
        (xfclose): Don't assume fileno (stdin) == STDIN_FILENO, etc.
        * src/split.c: Include unistd-safer.h.
        (cwrite): Use fd_safer.  Replace mystery constant 0666 with symbolic
        version, as POSIX requires.
        * src/sum.c (bsd_sum_file, sysv_sym_file):
        Use same pattern as elsewhere for checking for stdin.

        removed.

2005-04-09  Jim Meyering  <jim@meyering.net>

        * src/dd.c (quit): Define with ATTRIBUTE_NORETURN.

        Now that close_stdout closes standard output unconditionally,
        these workarounds for dd and cat are no longer necessary.
        * src/dd.c (close_stdout_wrapper): Remove function.
        (main): Call atexit with close_stdout, instead.
        * src/cat.c (close_stdout_wrapper): Likewise.
        Don't close STDOUT_FILENO explicitly; close_stdout does it.

        * src/system.h (__attribute__): Readability nit:
        Change this:
        #  define __attribute__(x)
        to this:
        #  define __attribute__(x) /* empty */

2005-04-09  Jim Meyering  <jim@meyering.net>

        * src/rm.c (usage): Mention that --recursive removes listed
        directories too, not just their contents.
        Say that by default, rm does not remove directories.

        * src/pr.c: Don't include "timespec.h".  system.h does that.
        * Makefile.maint (sc_system_h_headers): Propagate exit status
        through trap.

2005-04-08  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Document that dd no longer treats QUIT or PIPE specially,
        and when conforming to POSIX no longer treats USR1 specially.
        Document that dd no longer dumps core when handling signals.
        * src/system.h (RETSIGTYPE): Remove; no longer needed.  All uses
        replaced with void.
        * src/csplit.c (SA_NOCLDSTOP): Define to 0 if not defined.
        All uses changed.
        (siginterrupt) [!HAVE_SIGINTERRUPT]: New macro.

        Use siginterrupt to specify that system calls should be interrupted.
        * src/dd.c: Do not include safe-read.h or full-write.h; no longer needed.
        (process_signals): Add forward decl.

        (interrupt_handler): Simply record the signal and return.
        (siginfo_handler): Simply increment the signal counter and return.
        (install_handler): Remove, replacing with:
        (install_signal_handlers, process_signals, iread, iwrite):
        New functions.  All callers to safe_read and full_write replaced
        by iread and iwrite.  All callers to install_handler replaced by
        install_handlers.
        * src/ls.c (SA_NOCLDSTOP): Define to 0 if not defined.
        All uses changed.
        (siginterrupt) [! HAVE_SIGINTERRUPT]: New macro.
        (main) [! SA_NOCLDSTOP]: Use it.
        * src/shred.c: Remove all uses of signals; modern hosts have
        /dev/random and don't need this gorp.
        Do not include signal.h.
        (env, sigill_handler, isaac_seed_machdep): Remove.  All uses removed.
        * src/sort.c (SA_NOCLDSTOP): Define to 0 if not defined.

        instead of umaxtostr.
        (print_stats): Work even in languages that have special
        forms for two of things, for r_truncate and w_bytes.  We can't
        fix delta_s in this way, since ngettext doesn't support floating-point.
        (main): Rewrite to avoid casts.

2005-04-07  Jim Meyering  <jim@meyering.net>

        Don't let pr treat +1:-1 like +1:18446744073709551615.
        * src/pr.c (strtoumax): Remove declaration.
        (first_last_page): Use xstrtoumax in place of strtoumax,
        so we don't interpret a negative page number (e.g., in an option
        like --pages=1:-1) as valid.
        * tests/pr/Test.pm (neg-page): Add a test for this.

        * src/system.h (ptr_align): Declare `ptr' parameter to be a

2005-03-26  Paul Eggert  <eggert@cs.ucla.edu>

        * src/dcgen: Squeeze multiple blanks into one.  Output a simple
        array of adjacent strings rather than a more complicated data
        structure; this saves space in the dircolors executable.
        * src/dircolors.c (parse_line): Use char *, not unsigned char *.
        This avoids casts.
        (dc_parse_stream, main): Avoid casts.

2005-03-19  Jim Meyering  <jim@meyering.net>

        $(LIB_CLOCK_GETTIME) to get the required -lrt on newer Linux systems.

2005-03-18  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: pr -D "FORMAT" now accepts the same formats that
        date +"FORMAT" does.
        * src/pr.c: Include strftime.h, timespec.h.
        (init_header): Obtain and format nanosecond part of time stamp.

        * NEWS: nohup now ignores the umask when creating nohup.out.
        nohup now closes stderr if it is a terminal and stdout is closed.
        * src/nohup.c (main): Likewise.  Be a little more paranoid about
        return values; e.g., check for any negative return from open.
        Assume free (NULL) works.
        Close file descriptor leak when redirecting standard output to a file.

2005-03-17  Jim Meyering  <jim@meyering.net>

        * src/cut.c (set_fields): Use DECIMAL_DIGIT_ACCUMULATE macro,

        declaration.
        * src/system.h (VERIFY, VERIFY_EXPR, DECIMAL_DIGIT_ACCUMULATE):
        New macros.

        Before, this command would make uniq skip 11 fields and print
        only the first line:
        $ _POSIX2_VERSION=1 ./uniq -f1 -1 <(seq --format='1 %g' 2)
        1 1
        1 2
        * src/uniq.c (main): Interpret `uniq -f1 -1' like `uniq -f1',
        not like `uniq -f11'.

2005-03-15  Jim Meyering  <jim@meyering.net>

        Both `pr -0' and e.g., `pr -03' would evoke `column count too large'.
        `pr -0' should give a better diagnostic and `pr -03' should be
        equivalent to `pr -3'.
        * src/pr.c (parse_column_count): Change return type to void.
        Call error (EXIT_FAILURE, ... for an invalid string.
        (main): Allocate space for column_count_string using malloc.
        Accumulate all old-style column-count digits before converting.
        When the number of columns is specified via both old-style,
        (e.g., -3), and a long option (--columns=5), ensure that only
        the last one specified takes effect.
        * tests/pr/Test.pm: Add tests for the above.

2005-03-15  Corinna Vinschen  <corinna@vinschen.de>  (tiny change)

        Add a little infrastructure to help prevent future bugs like the
        one fixed below.
        * src/stat.c (xstrcat): New function.
        (print_statfs, print_stat): Add buf_len parameter and convert all
        uses of strcat to xstrcat.  Update callers.
        (print_it): Call print_func with buf_len parameter.

        Invoking stat -c FMT with a lone format directive of %s, %f, %h, %s,
        could cause a buffer overrun error.
        * src/stat.c (print_it): Allocate 2 more bytes, to accommodate our
        conversion of the stat %s format string to the longer printf %llu one.
        Patch from Guochun Shi.

2005-03-11  Paul Eggert  <eggert@cs.ucla.edu>

        * src/ls.c (TIME_STAMP_LEN_MAXIMUM): New constant.
        (long_time_expected_width, print_long_format): Use it, to avoid
        some possible denial-of-service attacks.
        * NEWS: Document this.

2005-03-11  Jim Meyering  <jim@meyering.net>

        Prompt once again for `mv -i A B' when A and B are hard links
        to the same file.  This fixes a bug introduced by my 2003-04-04
        (coreutils-5.0.1) change.  Reported by Thomas Wolff via Eric Blake.
        * src/copy.c (abandon_move): New function, factored out of
        copy_internal, now that this code is being used from two places.
        (copy_internal): Perform the same interactive-related test for
        whether it's alright to proceed and (usually) overwrite the
        destination file.
        * tests/mv/i-4: Add tests for the above.

        Don't segfault for a very long date format string, e.g.,
        ls -ld --time-style=+%99999999H .
        * src/ls.c (long_time_expected_width): Use x2nrealloc, not alloca,
        so format string abuse cannot provoke stack overflow.
        (print_long_format): Likewise.

        Don't segfault for a long header date string, e.g.,
        echo a|pr -D +%9999999A
        * src/pr.c (init_header): Use x2nrealloc, rather than alloca.
        Don't bother with fixed-sized initial buffer;  always use x*alloc.

        * src/pr.c (init_header): Use slightly clearer INT_BUFSIZE_BOUND
        in place of equivalent INT_STRLEN_BOUND + 1.
        * src/expr.c (tostring, printv): Likewise.

2005-03-09  Paul Eggert  <eggert@cs.ucla.edu>

        * src/system.h: Include intprops.h.
        (TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM, INT_STRLEN_BOUND): Remove;
        they are now defined in intprops.h.

2005-03-09  Jim Meyering  <jim@meyering.net>

        * TODO: Remove entry about named pipes.  It was fixed in 5.3.0.

2005-03-08  Paul Eggert  <eggert@cs.ucla.edu>

        * src/date.c (usage): Redo to match recent documentation changes.
        Don't bother documenting which usages are GNU extensions; the list
        wasn't correct, and is better left to the printed manual anyway.

2005-03-06  Jim Meyering  <jim@meyering.net>

        Factor out column-count processing.
        * src/pr.c: Include "inttostr.h".

        hosts with clock_gettime.

2005-02-20  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Describe user-visible change to dd.
        * src/Makefile.am (dd_LDADD, shred_LDADD, nanosec_libs):
        Remove $(LIB_CLOCK_GETTIME).  These functions now use
        gethrxtime instead.
        * src/dd.c: Include gethrxtime.h, xtime.h.
        (start_time): Now of type xtime_t, not struct timespec.
        (print_stats, main): Use gethrxtime rather than gettime.
        * src/ls.c (time): Remove obsolete decl.
        (get_current_time): gettimeofday always returns 0, so don't
        check its result.
        * src/shred.c: Include gethrxtime.h.
        (isaac_seed): Use gethrxtime rather than a mishmash.
        * src/touch.c (time): Remove obsolete decl.

        * tests/misc/split-fail: Don't assume that the current host
        supports integers wider than 32 bits.  Fix comment typo.
        * tests/od/x8: Likewise.

        * src/chown-core.c (enum RCH_status): Remove trailing comma,
        as it's not valid in standard C89.

2005-02-15  Jim Meyering  <jim@meyering.net>

        * src/stat.c (human_fstype): Add case/definition for S_MAGIC_XFS
        so that file systems of type `xfs' are recognized as such.
        * src/fs.h: Regenerate.
        Reported by Bernd Eckenfels.
        * src/stat.c (human_fstype): Likewise for S_MAGIC_JFS/jfs.
        * src/fs.h: Regenerate.
        Reported by Andreas Schwab.

        * src/nice.c (NZERO) [NZERO == 0]: Undefine and define to 20,
        to work around the invalid definition from Darwin 7.7.0.
        Test failure reported by Sébastien Maret.

2005-02-14  Paul Eggert  <eggert@cs.ucla.edu>

        * src/sort.c (mergefps): Use binary search rather than linear one

        Idea suggested by James Lemley.

2005-02-09  Jim Meyering  <jim@meyering.net>

        * src/copy.c (valid_options): Add an assertion that

        * doc/coreutils.texi (stat invocation): Normalize terminology,
        capitalization, and sort order to match --help output.  Mention %c
        for file systems.  Add new -f -c format %S, and document %s versus %S;
        problem reported by Jeroen van Wolffelaar.
        * src/stat.c (usage): Likewise.
        (STATFS_FRSIZE): New macro.

        systems that don't support sparse files.
        Check for $2 -ge 128, rather than $2 = 128, in case
        there is a file system type that doesn't support sparse files,
        yet for which metadata takes up additional space.
        Both reported by Andreas Schwab.

2005-02-01  Eric Blake  <ebb9@byu.net>  (tiny change)

        * tests/du/8gb: Create a larger test file, so we properly
        detect that sparse files can be created on NTFS under cygwin.

        * src/head.c (elide_tail_bytes_pipe): Correct wording in diagnostic.

        * src/stty.c: Remove unnecessary parentheses in all #if directives.

2005-01-29  Eric Blake  <ebb9@byu.net>  (tiny change)

        * .cvsignore: Ignore config.cache and config.status.lineno.
        * src/stty.c [VSWTCH]: Some systems, like Cygwin, use VSWTC
        instead of VSWTCH, for use with CSWTCH.

2005-01-29  Eric Blake  <ebb9@byu.net>  (tiny change)

        * tests/Makefile.am (.PHONY): Add check-root and root-hint.
        * tests/rwx-to-mode: Ignore ACL designation.
        * tests/setgid-check: Likewise.
        * tests/chown/separator: Quote user and group names.

2005-01-24  Jim Meyering  <jim@meyering.net>

        * src/cp.c (usage): Merge the descriptions of --no-dereference and -P.
        Suggestion from Johan Boule.

2005-01-17  Eric Blake  <ebb9@byu.net>  (tiny change)

        * src/Makefile.am (all_programs.list): Strip $(EXEEXT) and remove
        duplicates.
        * man/Makefile.am (all_programs): Revert previous patch; updated
        all_programs.list fixes this.
        (.x.1): No need to add $(EXEEXT).

2005-01-03  Corinna Vinschen  <corinna@vinschen.de>  (tiny change)

        * src/system.h: Use S_BLKSIZE value for ST_NBLOCKSIZE where
        available.

2005-01-22  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (v_etc_file): The version string has moved to
        version-etc-fsf.c, search that new file, not version-etc.c.

2005-01-17  Paul Eggert  <eggert@cs.ucla.edu>

        * tests/group-names: Use numeric group ids, not symbolic group names,
        since the latter can have shell metacharacters in them (e.g., spaces).
        Problem reported by Eric Blake.
        * tests/chgrp/basic: Assume groups are numeric, not symbolic.
        * tests/chgrp/deref: Likewise.
        * tests/chgrp/posix-H: Likewise.
        * tests/chgrp/recurse: Likewise.

2005-01-15  Jim Meyering  <jim@meyering.net>

        * src/shred.c (isaac_seed) [HAVE_GETHRTIME]: #if-0 this block,
        because just calling gethrtime evokes an `illegal instruction'
        failure when compiled with Sun's c89 on Solaris 8 and 9.
        Reported by Nelson Beebe.

        * src/shred.c (isaac_seed) [HAVE_GETHRTIME]: Don't call ISAAC_SEED
        twice with the same value of `t'.
        Replace nested #if-#else blocks with #if-#elif-#elif chain.

2005-01-14  Jim Meyering  <jim@meyering.net>

        The test, tests/tail/f-1, failed on powerpc-apple-darwin7.7.0.
        * src/tail.c (IS_TAILABLE_FILE_TYPE): Adjust definition also to include
        sockets, since that's what you get when reading from a command-line-
        supplied pipe on Darwin 7.7.
        (IS_PIPE_LIKE_FILE_TYPE): Define.
        (main): Use new IS_PIPE_LIKE_FILE_TYPE rather than simply S_ISFIFO.
        Reported by Nelson Beebe.
        This same change is also required on NetBSD/sparc-1.5.
        Reported by Adrian Bunk.

        * src/expr.c (toarith): Rewrite to detect/diagnose integer overflow,
        rather than suffering silently.
        Before, expr would silently overflow and wrap around:
          $ expr 9223372036854775808 = 0   # $(echo 2^63|bc)
          1
        Now it detects the problem and exits nonzero:
          $ ./expr $(echo 2^63|bc) = 0
          ./expr: 9223372036854775808: integer is too large

        * tests/chown/separator (id_gn): Exit 77, not 1, for a test-framework
        failure, so that doesn't cause `make check' to stop.  Nelson Beebe
        reported that this test would fail with the diagnostic,
        `cannot find name for group ID 10', on one of his systems.

2005-01-13  Jim Meyering  <jim@meyering.net>

        * src/test.c (is_int): Don't overflow when evaluating integer
        constants.  Before, ./test $(echo 2^64|bc) -eq 0 && echo FAIL
        would print `FAIL'.

        * tests/Fetish.pm (run_tests): Add code (if-0'd out) to detect
        names of temporary files that would clash on 8.3 file systems.
        * tests/mk-script (validate): Likewise.

2005-01-12  Jim Meyering  <jim@meyering.net>

        * tests/dd/skip-seek: Shorten test names to accommodate 8.3 systems.

        * tests/tr/Test.pm (repeat-xC): Change test name from
        `repeat-Compl', to avoid 8.3 conflict with `repeat-compl'.
        Reported by Eric Blake.
        (repeat-000): Rename to `repeat-zeros' for the same reason.

2005-01-11  Jim Meyering  <jim@meyering.net>

        * configure.ac: Update version to 5.3.1.

2005-01-11  Eric Blake  <ebb9@byu.net>

        * src/Makefile.am (check-README, check-AUTHORS): Account for $(EXEEXT).
        * man/Makefile.am (all_programs): Account for $(EXEEXT).

2005-01-11  Jim Meyering  <jim@meyering.net>

        * src/unexpand.c (add_tab_stop): Properly diagnose a tabstop list
        with decreasing values.

        * src/expand.c (main): Likewise.
        * src/unexpand.c (main): Check for overflow in tabstop values
        specified via the obsolete form.  E.g., now this command fails:
        _POSIX2_VERSION=1 ./unexpand -$(echo '2^64+1'|bc)
        Before it would act like `_POSIX2_VERSION=1 ./unexpand -1'.
        * tests/unexpand/basic-1 (obs-ovflo): New test for this.

2005-01-10  Paul Eggert  <eggert@cs.ucla.edu>

        Respond to POSIX interpretations about pathchk -p dated 2005-01-06.
        * NEWS: Document the changes.
        * doc/coreutils.texi (pathchk invocation): Likewise.
        * src/pathchk.c (PORTABILITY_OPTION): New constant.
        (longopts, usage, main, validate_file_name):
        Add support for new -P option.
        Reject empty file names (unless -p is not specified and the
        current system allows empty file names).
        Change --portability so that is now equivalent to -p -P.
        Don't test whether file name is too long, if it is known to exist.
        (no_leading_hyphen): New function.
        * tests/misc/pathchk1: Add tests for empty file names and
        pathchk -P.

2005-01-08  Jim Meyering  <jim@meyering.net>

        * Version 5.3.0.

        `pr --columns=N' was not equivalent to `pr -N' when also using
        either -s or -w.

        * src/pr.c (main): Set `explicit_columns' for --columns=N,
        not just for -N.  This bug has existed since the introduction
        of the --columns=N option on 1998-08-15.
        * NEWS: Document this.
        * tests/pr/Test.pm (test_vector): For each -N test, automatically
        create a new test vector using --columns=N.

2005-01-07  Paul Eggert  <eggert@twinsun.com>

        * src/pr.c (main): Check for column count overflow with
        usages like "pr -2147483648".

2005-01-07  Jim Meyering  <jim@meyering.net>

        * src/pr.c (init_fps): Use xnmalloc, rather than xmalloc.

2005-01-06  Jim Meyering  <jim@meyering.net>

        * README: List the precise HP-UX version numbers that are affected.
        Suggestion from Bob Proulx.

        * Makefile.maint (sc_changelog): Specify find's `-maxdepth 2'
        predicate before `-name ChangeLog' to avoid a harmless warning
        from find-4.2.10.

2005-01-05  Jim Meyering  <jim@meyering.net>

        * tests/help-version: Punt on the uptime test, since it fails when
        it can't get boot time, and I don't want that to stop `make check'.

        * src/du.c (process_file): Evaluate exclusion rules against
        the entire file name, not just the last component.
        Reported by Robert Lindgren.
        * tests/du/exclude: Test for this.
        * NEWS: Document this.

        Ensure that tests/Makefile.am's check-root actions stay up to date.
        * Makefile.maint (sc_root_tests): New rule.
        (syntax-check-rules): Add it to the list.

2005-01-04  Jim Meyering  <jim@meyering.net>

        * man/shred.x: Change one-line summary to reflect that shred does
        not remove files by default.  Suggestion from Helen Faulkner in
        http://bugs.debian.org/288552

        * README: Request VERBOSE=yes output when reporting test failures.
        Other minor changes.

        * tests/Makefile.am (check-root): Update.

2005-01-03  Paul Eggert  <eggert@cs.ucla.edu>

        * src/system.h: Undo previous change; we now use Autoconf.

2005-01-03  Jim Meyering  <jim@meyering.net>

        * tests/stty/row-col-1: Don't set rows or columns to zero, to avoid
        a bug in the TIOCGWINSZ ioctl on at least Solaris5.9 systems.  Setting
        either (or both) to zero would succeed, but subsequent `stty size'
        would say `no size information for this device' due to the ioctl
        failing with EINVAL.

        * src/system.h: If PRIdMAX, PRIoMAX, PRIuMAX, and PRIxMAX are
        not all defined and either ULONG_MAX or ULLONG_MAX is not defined,
        then fail at compile-time rather than let tools like od produce
        invalid results at run time.

2004-12-21  Jim Meyering  <jim@meyering.net>

        * src/csplit.c (usage): Say the default names are `xx00, xx01, ...',
        not `xx01, xx02, ...'.
        Reported by Matt Kraai in http://bugs.debian.org/286605

        * tests/misc/split-fail: Avoid spurious failure on x86 Solaris5.9
        when using c89.

2004-12-20  Paul Eggert  <eggert@cs.ucla.edu>

        * src/split.c (usage): Mention default size.  Suggested by Dan Jacobson.

2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Mention that one should eval "`dircolors`" rather than
        `dircolors`.

2004-12-17  Jim Meyering  <jim@meyering.net>

        * tests/mv/hard-link-1: Rearrange to use newer trap-handling code,
        so temporary directories aren't left behind upon e.g., interrupt.

2004-12-16  Paul Eggert  <eggert@cs.ucla.edu>

        * src/ls.c (print_dir): Use "%s: not listing already-listed
        directory", not "not listing already-listed directory: %s", to
        format already-listed directories, to be consistent with other
        diagnostics involving file names and colons.

2004-12-15  Jim Meyering  <jim@meyering.net>

        * src/Makefile.am (__LDADD): Define, so that building `[' on
        Solaris still uses the -lgen library that it requires in order
        to get a definition of eaccess.

2004-12-14  Jim Meyering  <jim@meyering.net>

        tac would exit immediately upon I/O or temp-file creation failure.
        Now it continues on, processing any remaining command line arguments.

        * src/tac.c: Include quotearg.h.
        Use quotearg_colon in most diagnostics.
        (copy_to_temp): Rewrite not to exit upon I/O or temp-file-creation
        failure.  Before, this command (with /full/tmp being a full partition)
          TMPDIR=/full/tmp ./tac /proc/modules tac.c
        would exit immediately upon the write error while trying to copy
        non-seekable /proc/modules to the full partition.  Now it still
        reports the failure but continues on with the remaining file.
        (tac_nonseekable): Return false also if copy_to_temp fails.
        [DONT_UNLINK_WHILE_OPEN]: Add a FIXME comment explaining that
        using atexit like this is wrong.
        * NEWS: Document this.
        * tests/misc/tac-continue: New test for this.
        * tests/misc/Makefile.am (TESTS): Add tac-continue.

        * tests/chown/basic: Add a few more tests.

2004-12-13  Paul Eggert  <eggert@cs.ucla.edu>

        * src/ls.c (gobble_file): Change arg name to be command_line_arg
        rather than explicit_arg, for consistency with copy.c.
        (extract_dirs_from_files): Remove ignore_dot_and_dot_dot arg, since
        it is deducible from dirname arg.  All callers changed.
        (extract_dirs_from_files, print_dir, queue_directory):
        Add command_line_arg arg.  All callers changed.
        (struct pending): Add command_line_arg member.
        (main): Use NULL rather than 0 when appropriate.
        (set_exit_status, file_failure): New functions.
        (queue_directory): Store command_line_arg into new structure.
        (print_dir, gobble_file, get_link_name):
        Use file_failure to report problems in accessing files,
        so that the exit status is set consistently.
        (print_dir): Simplify readdir failure code yet again.
        If closedir fails, report "closing directory" rather than "reading
        directory" failure.
        (xstrcoll): Use set_exit_status to set status on failure.
        * tests/ls-2/tests (no-a-isdir-b): This now exits with status 2,
        not status 1.

2004-12-11  Jim Meyering  <jim@meyering.net>

        Avoid a race condition vulnerability in chown, when used with
        --from=O:G and without the (-h) --no-dereference option.
        * src/chown-core.c (restricted_chown): New function.
        (change_file_owner): Call it.
        Reported by Ulrich Drepper.
        * NEWS: Mention this.

2004-12-09  Paul Eggert  <eggert@cs.ucla.edu>

        * ls now exits with status 1 on minor problems, 2 if serious trouble.
        * NEWS: Document this.
        * src/ls.c (LS_MINOR_PROBLEM, LS_FAILURE): New constants.
        All uses of EXIT_FAILURE replaced with LS_FAILURE, unless
        specified below.
        (main): Initialize exit failure to LS_FAILURE.
        (print_dir, gobble_file, get_link_name, xstrcoll):
        Set exit status to LS_MINOR_PROBLEM if the failure is minor.
        (print_dir): Do not give up on entire directory merely because readdir
        returns EOVERFLOW.
        (usage): Explain exit status.
        * tests/help-version: ls and variants now exit with status 2
        on serious trouble.

2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Document new UTC+HH:MM date syntax, and put date changes
        together.

2004-12-07  Paul Eggert  <eggert@cs.ucla.edu>

        * src/factor.c (factor): Don't list 1 as a factor of 1.
        Problem reported by Thomas Folz-Donahue.

2004-12-06  Jim Meyering  <jim@meyering.net>

        * tests/du/files0-from: Sanitize environment.
        Otherwise, e.g., BLOCKSIZE=k would cause a failure, and that
        setting is the default (exported from /etc/profile) on at least one
        NetBSD 1.6 system.
        * tests/du/no-deref: Likewise.
        * tests/cp/symlink-slash: Likewise.
        * tests/ls/symlink-slash: Likewise

2004-12-05  Jim Meyering  <jim@meyering.net>

        * tests/tail/Test.pm (err-6) ["tail -c"]: Avoid test failure when
        _POSIX2_VERSION=199209 is in the environment, or when building on
        e.g., OpenBSD 3.2.

2004-12-04  Jim Meyering  <jim@meyering.net>

        * NEWS: Mention cut's new --complement option.

2004-10-01  Paolo Bonzini  <bonzini@gnu.org>

        * cut.c (complement, COMPLEMENT_OPTION): New.
        (longopts): Add --complement.
        (usage): Say not that -b, -c, and -f `print' fields,
        but rather that they `select' fields for printing.
        Describe the new --complement option.
        (mark_range_start): Extracted from set_fields.
        (print_kth): Support --complement.
        (compare_ranges): New function.
        (set_fields): Rewrite the part that populates range_start_ht,
        merging it with the part that populates printable_field.
        (main): Handle --complement.

2004-12-03  Paul Eggert  <eggert@cs.ucla.edu>

        * src/tail.c (tail_file): Set errnum to -1 if the initial "tail"
        failed.  This works around an assertion failure reported by
        Roberto Nibali in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-12/msg00012.html

2004-12-02  Jim Meyering  <jim@meyering.net>

        With using --color and with LS_COLORS saying not to color
        executables, don't stat every file.
        * src/ls.c (is_colored): New function.
        (gobble_file): Use it.
        (main): Use it here, in place of too-strict tests against NULL:
        if either ORPHAN or MISSING was set to 0 from LS_COLORS, the
        old test would fail.

2004-12-01  Paul Eggert  <eggert@cs.ucla.edu>

        * src/comm.c (compare_files): Assume setlocale exists.
        * src/join.c (keycmp): Likewise.
        * src/seq.c (decimal_point): Treat like sort.  Now char.
        All uses changed.
        (main): Assume localeconv exists.  Use same code as sort.
        * src/sort.c (C_DECIMAL_POINT): Remove.  Use changed to '.'.
        Assume setlocale exists.
        (thousands_sep): Renamed from th_sep.
        (IS_THOUSANDS_SEP): Remove.  All uses replaced by comparisons.
        (NONZERO): Parenthesize use of arg.
        (numcompare): Avoid duplicate loads.  Use ISDIGIT as boolean, for
        consistency.  Avoid unnecessary negation by reversing
        fraccompare args.
        (main): Rewrite localeconv call to match seq.c.
        * src/system.h: Assume locale.h exists.
        (HAVE_SETLOCALE): Remove.
        * src/uniq.c (different): Assume setlocale exists.

        * src/ls.c (sort_files): Minor cleanup.  Remove an unnecessary
        'volatile' on a local variable.  Rewrite to avoid unnecessary
        double-assignment to 'func' in the usual case where strcoll does
        not fail.

2004-11-30  Paul Eggert  <eggert@cs.ucla.edu>

        * src/pinky.c (gethostname): Remove decl.
        (scan_entries): Use IS_USER_PROCESS instead of by-hand code.
        * src/uptime.c (print_uptime): Use IS_USER_PROCESS and
        UT_TYPE_BOOT_TIME instead of by-hand code.
        * src/users.c (list_entries_users): Use IS_USER_PROCESS
        instead of by-hand code.
        * src/who.c (USER_PROCESS, RUN_LVL, INIT_PROCESS, LOGIN_PROCESS,
        DEAD_PROCESS, BOOT_TIME, NEW_TIME, UT_TYPE_UNDEF, UT_TYPE): Remove.
        (IS_USER_PROCESS): Move to ../lib/readutmp.h.
        (UT_TYPE_RUN_LVL, UT_TYPE_INIT_PROCESS, UT_TYPE_LOGIN_PROCESS,
        UT_TYPE_DEAD_PROCESS, UT_TYPE_NEW_TIME): New macros.
        (gethostname): Remove decl.
        (list_entries_who, scan_entries): Use the new macros defined above,
        for consistency with pinky, uptime, and users.

2004-11-25  Paul Eggert  <eggert@cs.ucla.edu>

        Fix problem reported by Scott S. Tinsley for HP-UX 11.11 using
        HP's ANSI C compiler.  Declaring int functions causes warnings on
        some modern systems and shouldn't be needed to compile on ancient
        ones.
        * src/copy.h (stat, lstat, rename): Remove decls.
        * src/install.c (stat): Remove decl.
        * src/ln.c (link, symlink): Remove decls.

2004-11-25  Jim Meyering  <jim@meyering.net>

        * man/help2man: Import help2man-1.35.1.
        * man/Makefile.am (.x.1): Remove now-unnecessary use of
        locally-added --program-name=NAME option.  Now, help2man gets
        the name from the [NAME] section (i.e. from our .x file).
        * man/install.x: Use `install', not `ginstall' in the one-line
        description.  Reported by Brendan O'Dea.
        * man/sha1sum.x: Use `sha1sum', not `shasum'.

2004-11-24  Jim Meyering  <jim@meyering.net>

        Since the changes of 2004-05-22, the u.saved_cwd member at
        the bottom of the active-directory stack was no longer
        strictly necessary.  This change removes that member and uses
        the newer cwd_state parameter for the final restore_cwd.

        * src/remove.c (struct AD_ent) [u]: Remove now-unnecessary union.
        [dev_ino]: Rename from `a'.
        (AD_pop_and_chdir): Add a parameter to play the role of just-removed
        bottom-of-stack cwd-state member.
        (AD_pop_and_chdir): No longer return boolean.  Adjust caller.
        (AD_push_initial): Remove CWD parameter.  Adjust caller.

2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>

        Minor performance improvements and cleanups for "touch".
        * src/touch.c (posix_date): Remove; not needed as a static var.
        All uses rewritten.
        (touch): Use new futimens function to operate more efficiently
        in some cases.  Don't stat/fstat existing file when
        (!amtime_now && change_times == (CH_ATIME | CH_MTIME)); the
        old time stamps aren't needed in that case.
        (main): change_times is int, not bool.  Simplify test for
        change_times.

2004-11-20  Paul Eggert  <eggert@cs.ucla.edu>

        * src/install.c (usage): Avoid usage that runs afoul of Docbook
        translation.  Problem reported by Eric S. Raymond.

        Restore dd's noctty flag, reverting the change of 2004-04-08.
        POSIX does not allow "dd" to use O_NOCTTY by default.
        * NEWS: Add noctty flag to dd.
        * doc/coreutils.texi (dd invocation): Likewise.
        * src/dd.c (flags, usage, main): Likewise.

2004-11-19  Alfred M. Szmidt  <ams@gnu.org>

        * src/ls.c (usage): Clarified description of --no-group (-G),
        --human-readable (-h), --inode (-i), --size (-s), --time,
        and --time-style.

2004-11-19  Jim Meyering  <jim@meyering.net>

        * src/ls.c (usage): Clarify description of --author.
        Tweak indentation so that help2man creates better nroff.
        Reported by Dan Jacobson.

        * src/uniq.c (check_file): Don't check stdout for errors here.

        * src/pwd.c (find_dir_entry): Update comment to match reality.

2004-11-18  Jim Meyering  <jim@meyering.net>

        * src/pwd.c (robust_getcwd): Correct the comment: this function
        constructs the directory name.  The caller prints it.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * src/stat.c (STATFS): New macro, for portability to Solaris 9.
        (do_statfs): Use it.

        * src/basename.c, src/chroot.c, src/cksum.c, src/dd.c, src/dirname.c,
        src/factor.c, src/hostid.c, src/hostname.c, src/link.c, src/logname.c,
        src/nohup.c, src/printenv.c, src/pwd.c, src/setuidgid.c, src/sleep.c,
        src/sync.c, src/tsort.c, src/unlink.c, src/uptime.c, src/users.c,
        src/whoami.c, src/yes.c (main): Use getopt_long rather than getopt.
        * src/readlink.c (main): argv is not const.

        * src/cut.c (usage): Improve documentation along the lines suggested
        by Debian 5.2.1-2.
        * src/echo.c (usage): Likewise.
        * src/expr.c (usage): Likewise.

        * src/dircolors.hin: Add putty, screen-bce.

        * src/pinky.c (print_entry): Fix memory leak.
        * src/who.c (print_user): Likewise.

2004-11-15  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: New dd operand "status=noxfer".
        * src/dd.c (C_ASCII, C_EBCDIC, C_IBM, C_BLOCK, C_UNBLOCK,
        C_LCASE, C_UCASE, C_SWAB, C_NOERROR, C_NOTRUNC, C_SYNC, C_TWOBUFS,
        C_NOCREAT, C_EXCL, C_FDATASYNC, C_FSYNC): Now constants, not
        macros.
        (STATUS_NOXFER, statuses): New constants.
        (usage, print_stats, scanargs): Add support for status=noxfer.
        (usage): Update status output to match new behavior.
        (print_stats): Always output complete byte count.
        Put space between numbers and units, as SI requires.
        Use ngettext so that i18n can use plurals for "byte" and "second".
        Don't multiply by 1e-9 (inexact); divide by 1e9 (which is exact).
        (iflag_error_msgid, oflag_error_msgid): Remove; replace uses by
        the string.
        * tests/dd/skip-seek (@Tests): Use status=noxfer to avoid
        problems with regression testing.

2004-11-14  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: dd now outputs total bytes, seconds, and bytes per second.
        * src/Makefile.am (dd_LDADD): Add $(LIB_CLOCK_GETTIME).
        * src/dd.c: Include "human.h".
        (w_bytes, start_time): New vars.
        (usage): Document new I/O statistics output
        (print_stats): Output new I/O statistics.
        (cleanup): Do statistics after closing stdin and stdout, so that
        the times are more accurate.
        (write_output, dd_copy): Count output bytes.
        (main): Get initial value of clock.

2004-11-14  Jim Meyering  <jim@meyering.net>

        Backslash-escape `-'s in email addresses, so that they are
        rendered properly in UTF-locales.
        * man/help2man (escape_hyphens): New function.
        (main): Call it on email addresses.

        * src/sort.c (zaptemp): Mark new diagnostic for translation.

        * tests/misc/close-stdout: New file.  Test today's closeout.c change.
        * tests/misc/Makefile.am (TESTS): Add close-stdout.

2004-11-13  Jim Meyering  <jim@meyering.net>

        * src/test.c (usage): Put the description of `[-n] STRING'
        on two lines, one for `-n STRING' and one for `STRING' so that
        help2man properly escapes the `-'.  Otherwise, the hyphen is
        rendered inappropriately in UTF-8 locales.
        Reported by Uwe Zeisberger in http://bugs.debian.org/281069.

2004-11-12  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Document the following changes.

        * src/sort.c: Avoid O(N**2) behavior when there are many temporary
        files.
        (temptail): New variable, so that we can easily append to list.
        (create_temp_file): Create new files at end of list, so that
        searching the list has O(N*NMERGE) behavior instead of O(N**2).
        (zaptemp): Update temptail if needed.
        (mergefps, merge): Accept new arg that counts temp files, and keep it
        up to date as we create and remove temporaries.  This is for
        efficiency, so that we don't call zaptemp so often.
        All callers changed.
        (sort): Don't create array in reverse order, since the list of
        temporaries is now in the correct order.

        (zaptemp): Protect against race condition: if 'sort' is
        interrupted in the middle of zaptemp, it might unlink the
        temporary file twice, and the second time this happens the file
        might already have been created by some other process.

        (zaptemp): Warn if a temporary file is not removed.

        (create_temp_file): Use offsetof for clarity.
        (die): Move it up earlier, to clean up the code a bit.

        * src/pr.c (strtoumax): Declare if not declared.
        (skip_to_page, first_page_number, last_page_number, page_number,
        first_last_page, print_header):
        Use uintmax_t for page numbers.
        (first_last_page): Remove unnecessary forward declaration.
        Do not modify arg (it is now a const pointer).
        Return a true if successful, false (without print a diagnostic)
        otherwise.
        (main): If +XXX does not specify a valid page range, treat it
        as a file name.  This follows the response to Open Group XCU ERN 41
        <http://www.opengroup.org/sophocles/show_mail.tpl?source=L&listname=austin-group-l&id=7717>,
        which says the behavior is allowed.
        (skip_to_page): When starting page number exceeds page count,
        print both numbers in the diagnostic.
        (print_header): Detect page number overflow.

2004-11-07  Jim Meyering  <jim@meyering.net>

        * src/uname.c [__APPLE__]: Include <mach/machine.h> and <mach-o/arch.h>.
        (main) [__APPLE__]: Get the processor type via syscall rather than
        hard-coding "powerpc".  From Toby Peterson.

        * src/sort.c (merge): Remove declarations of now-unused variables.

2004-11-06  Paul Eggert  <eggert@cs.ucla.edu>

        * src/sort.c (first_same_file): Remove.  Move most of the code to....
        (avoid_trashing_input): New function.
        (merge): Avoid some silly merges, e.g., copying a single file to
        a temporary file when there are exactly 17 input files to merge.
        Take a count of temporary files rather than a max_merge arg.
        All uses changed.

2004-11-06  Jim Meyering  <jim@meyering.net>

        * src/sort.c (xfclose): Don't close stdout here (just flush it),
        since close_stdout now closes stdout unconditionally.

2004-11-05  Paul Eggert  <eggert@cs.ucla.edu>

        * src/sort.c (inittables, sort_buffer_size, getmonth, mergefps,
        first_same_file, merge, sort, main): Use size_t for indexes to arrays.
        This fixes some unlikely havoc-wreaking bugs (e.g., more than INT_MAX
        temporary files).
        (getmonth, keycompare, compare): Rewrite to avoid need for alloca,
        thus avoiding unchecked stack overflow in some cases.  As a side
        effect this improve the performance of "sort -M" by a factor of 4
        on my benchmarks.

2004-11-03  Paul Eggert  <eggert@cs.ucla.edu>

        * src/stty.c: Include "vasprintf.h" since we use vasprintf now.

        * src/Makefile.am (check-AUTHORS): Don't assume \? works in a sed
        expression; it's not portable.  Problem reported by Albert Chin.
        Don't invoke a program more than once.
        * src/groups.sh (version): New variable, containing author info,
        for benefit of AUTHORS check.  Use it when acting on --version option.
        * AUTHORS: Remove duplicate lines.  Remove bogus "chroot:"
        in groups line.

        * src/system.h: Don't #define and #undef getopt around <stdlib.h>,
        as this breaks the new regime that does "#define getopt rpl_getopt".
        Problem reported by Albert Chin for Solaris 9 with Sun cc in:
        http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00019.html
        I suppose this may cause problems on ancient hosts with
        incompatible getopt declarations, but we'll cross that bridge if
        the problem gets reported to us by someone who can test the fix.

2004-11-03  Jim Meyering  <jim@meyering.net>

        * src/tac.c: quote(...) file names in diagnostics.

2004-10-29  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Document getdate changes.

2004-10-29  Jim Meyering  <jim@meyering.net>

        * src/tac.c (tac_file): Remove temporary prototype and move this
        function `down' so that it precedes definition of tac_nonseekable.

        `tac /proc/modules' would print nothing
        Reported by Harald Dunkel in http://bugs.debian.org/278604.

        * src/tac.c (copy_to_temp): Renamed from save_stdin, since
        now it copies a general file descriptor, not just stdin.
        (tac_nonseekable): Renamed/adapted from tac_stdin.
        (tac_file): Get fd via `open' directly rather than via fopen/fileno,
        since we never used the stream.  Perform "-" to stdin mapping here
        rather than in main.  Determine whether a file is seekable,
        by trying to `lseek' to its end, and dispatch to tac_seekable or
        tac_nonseekable accordingly.
        (main): Rewrite argument handling now that it uses only tac_file.
        * NEWS: Mention it here.

2004-10-21  Jim Meyering  <jim@meyering.net>

        * tests/mv/leak-fd: New file.
        * tests/mv/Makefile.am (TESTS): Add it.
        * tests/rm/dot-rel: New file.
        * tests/rm/Makefile.am (TESTS): Add it.

        Correct my patch of 2004-10-18.
        * src/remove.c (rm): Destroy the saved_cwd here (via cwd_state),
        if necessary, not in remove_dir.  Otherwise, removing multiple
        `.'-relative nonempty directories no longer worked.

2004-10-20  Paul Eggert  <eggert@cs.ucla.edu>

        * src/fmt.c (usage): Improve description of --prefix.
        Problem reported by Edward Welbourne.

        * man/uniq.x: Change summary so that it doesn't imply that
        uniq writes to its input file.  Problem reported by
        Dan Jacobson.

2004-10-18  Jim Meyering  <jim@meyering.net>

        Plug a leak that would cause a cross-device mv to fail when
        operating on too many command-line-specified nonempty directories.
        * src/remove.c (remove_dir): Destroy the `struct saved_cwd' on the
        top of the stack before returning.  This usually closes the file
        descriptor that was used to return to the original working directory.
        Reported by Cyril Bouthors in
        http://article.gmane.org/gmane.comp.gnu.core-utils.bugs/3048
        * NEWS: Mention it here.

        * src/pathchk.c (validate_file_name): Give a more descriptive
        diagnostic when pathconf fails.  This also avoids an unwarranted
        warning from gcc-3.3.5 about a format not being a string literal.

        * src/sleep.c (main): Remove declaration of unused local, c.
        * src/printenv.c (main): Likewise.
        * src/logname.c (main): Likewise.
        * src/uptime.c (main): Likewise, for optc.
        * src/tsort.c (main): Likewise, for opt.

2004-10-17  Paul Eggert  <eggert@cs.ucla.edu>

        * AUTHORS: Add self to pathchk.
        * src/pathchk.c (AUTHORS): Add self.
        Change "path" to "file name" whenever possible.
        Remove usage comment, as it was a duplication of the code or doc.
        Include <wchar.h> if available.
        (mbrlen, mbstate_t) [! (HAVE_MBRLEN && HAVE_MBSTATE_T)]: Define.
        (NEED_PATHCONF_WRAPPER, PATH_MAX, PATH_MAX_FOR, NAME_MAX,
        pathconf_wrapper, portable_chars, dir_ok): Remove.
        (NAME_MAX_MINIMUM, PATH_MAX_MINIMUM): New macros.
        (pathconf, _PC_NAME_MAX, _PC_PATH_MAX): Define if nonexistent.
        (portable_chars_only): New arg FILELEN.
        Don't assume ASCII; we might be on an EBCDIC host.
        Don't assume unibyte locale in diagnostic.
        (component_start, component_len): New functions.
        (validate_file_name): Renamed from validate_path.  All uses changed.
        Pretty much a complete rewrite.
        Don't make copy of file arg.  Always append trailing slash to
        pathconf arg, just in case it's a symlink (this is pure paranoia;
        we don't know of any hosts where the trailing slash is required).
        Use size_t instead of long int when possible.
        Avoid need to call pathconf in most practical cases.
        Don't use euidaccess several times to test searchability;
        just use lstat once.  Reword diagnostic to put the (often very long)
        file names last.

2004-10-15  Paul Eggert  <eggert@cs.ucla.edu>

        * src/printf.c (usage): Mention Unicode, and use H for hex digits.

2004-10-13  Jim Meyering  <jim@meyering.net>

        * NEWS: Mention today's fts.c fix.

2004-10-13  Paul Eggert  <eggert@cs.ucla.edu>

        * tests/stty/row-col-1: Set LC_ALL=C.

2004-10-12  Jim Meyering  <jim@meyering.net>

        * src/dircolors.hin: Add .flac and .mpc as audio suffixes.
        From Jesus Climent in http://bugs.debian.org/276149.

2004-10-05  Paul Eggert  <eggert@cs.ucla.edu>

        * src/ls.c (ignore_mode): Renamed from ignore, to avoid shadowing
        problems.  All uses changed.

2004-10-05  Jim Meyering  <jim@meyering.net>

        * .x-sc_trailing_blank: Add an exclusion for config/texinfo.tex,
        since Karl says its trailing blanks are there to stay :-)

2004-10-04  Paul Eggert  <eggert@cs.ucla.edu>

        * src/expr.c (NEW, OLD): Remove, partly to avoid
        reference to obsolescent macro XMALLOC.
        All uses replaced by xmalloc and free.

2004-09-28  Jim Meyering  <jim@meyering.net>

        * src/tail.c (usage): Clarify: --retry works only with --follow=name.
        Reported by Nik A. Melchior in http://bugs.debian.org/273781.

2004-09-27  Paul Eggert  <eggert@cs.ucla.edu>

        * src/od.c (format_address_paren): c is optional, so don't output
        it if it's '\0'.

2004-09-26  Paul Eggert  <eggert@cs.ucla.edu>

        Add support for ls --hide.  Idea suggested by Bardur Arantsson.
        * NEWS: Document this.
        * src/ls.c (file_ignored): Renamed from file_interesting, with
        inverted return value.  Accept the file name, not a struct dirent *.
        All uses changed.  Avoid the expense of calling fnmatch if the
        file is ignorable due to leading '.'.
        (all_files, really_all_files): Removed; replaced by:
        (ignore): New variable.  All uses changed.
        (IGNORE_DEFAULT, IGNORE_DOT_AND_DOTDOT, IGNORE_MINIMAL, HIDE_OPTION):
        New constants.
        (hide_patterns): New variable.
        (long_options, decode_switches, file_ignored, usage):
        Add support for --hide.
        (patterns_match): New function.
        (usage): Replace "hide" with "ignore" in explanation, to avoid
        confusion.

2004-09-25  Paul Eggert  <eggert@cs.ucla.edu>

        * src/ls.c (gobble_file, print_long_format): Don't assume that
        human-readable output has a byte count equal to its column width;
        this isn't always true in locales where the radix character is not
        '.' or ','.
        (format_user_or_group): Revamp code to match the above fix;
        this avoids the (very faint) possibility of integer overflow.

2004-09-24  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Mention that "chmod -r -w x" now works as expected.
        * src/chmod.c (main): Revamp option processing to support this.
        * tests/chmod/Makefile.am (TESTS): Add 'usage'.
        * tests/chmod/usage: New set of tests for usage like that.

2004-09-24  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (CVS_LIST): Use --types=AFGM option so that
        it lists only cvs-controlled regular files.

        * src/csplit.c (xalloc_die): Declare to be `extern', not `static'
        to avoid a warning from gcc-3.4.1.  Reported by Paul Eggert.

2004-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        * Makefile.maint (CVS_LIST): New macro.
        (sc_space_tab, sc_prohibit_atoi_atof, sc_file_system,
        sc_prohibit_jm_in_m4, sc_system_h_headers, sc_sun_os_names,
        sc_trailing_blank, po-check): Use it instead of the
        nonstandard "cvsu --list".

        * src/tail.c (parse_obsolete_option): Bring back support
        for obsolete option followed by non-obsolete, or by more
        than one file.  When obsolete, conform to SUSv2 rather than
        original POSIX 1003.2-1992, as SUSv2 corrected the case of
        "tail -c".  Add support for the SUSv2 "b" modifier.
        * NEWS: Mention the above.
        * tests/tail/Test.pm: New test case obs-b to check the above.
        err-[134] no longer need _POSIX2_VERSION=199209.
        Fix comments to match revised behavior.

2004-09-22  Jim Meyering  <jim@meyering.net>

        * Use automake-1.9.2.  Regenerate dependent files.

        * src/remove.c (struct dirstack_state) [current_arg_jumpbuf]:
        Improve the comment.

        Clean up scoping etc. so that some make `distcheck' tests pass.
        * src/csplit.c (xalloc_die): Declare to be static.
        * src/chown-core.c (chown_files): Declare as `extern'.
        * src/cp-hash.c (remember_created): Likewise.
        * src/copy.c (copy): Likewise.
        * src/checksum.h (enum) [ALG_MD5]: Define to be 1, not 0.

2004-09-21  Jim Meyering  <jim@meyering.net>

        * man/rm.x: Say "the response is affirmative" rather than "the
        response begins with y or Y", so that the documentation is
        accurate in non-English locales.  Problem reported by Munzir Taha.

2004-09-19  Paul Eggert  <eggert@cs.ucla.edu>

        * src/echo.c (main): Don't pass NULL to strcmp when

        * NEWS: Document this.

        * tests/rm/fail-eperm: Don't try to remove writeable files in a
        sticky /tmp directory, as SVR4-like systems (e.g., Solaris 9) let
        you remove such files.  Problem reported by Bert Fischer in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-09/msg00074.html

2004-09-18  Paul Eggert  <eggert@cs.ucla.edu>

        * src/md5sum.c (STATUS_OPTION, STRING_OPTION): New enums.
        (long_options, main): Use them instead of magic numbers 2 and 1.
        For --string, optarg can't possibly be NULL.

        * src/dd.c (usage): Distinguish between options and operands.
        (scanargs): Don't mess with argc, argv; getopt_long handles this now.
        Say "operands" for operands, not "options".
        (main): Use getopt_long, so that "dd --" works as POSIX requires.
        * tests/dd/misc: Check for "dd --".

        * src/chroot.c (main): Reject unknown options instead of
        interpreting them as a directory to chroot to.

        * src/cksum.c: Remove obsolete comment about POSIX 1003.2/D11.2.
        The current standard (POSIX 1003.1-2004) is correct.
        (crc_remainder) [defined CRCTAB]: Renamed from "remainder" to avoid
        collision with builtin function.
        (main) [defined CRCTAB]: Output in lowercase hexadecimal, and
        output the first 0 as 8 digits, to make it easier to compare to
        the text of the standard.  Output crctab to be a const array.
        (crctab): Use result of above changes.
        (long_options): Remove; not needed if empty.
        (main): getopt_long can't return 0 here, so simplify the code.

2004-09-13  Jim Meyering  <jim@meyering.net>

        * src/Makefile.am (localedir.h): Don't redirect directly to target.

2004-09-13  Paul Eggert  <eggert@cs.ucla.edu>

        because a user or group number can't be turned into a name.
        Problem reported by Felipe Kellermann in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-09/msg00081.html

2004-09-12  Jim Meyering  <jim@meyering.net>

        require -Wshadow.

2004-09-10  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: "tail" now handles obscure POSIX 1003.2-1992 cases better.
        * src/tail.c (parse_obsolete_option): Renamed from
        parse_obsolescent_option, since the options are obsolete now.
        Remove bool *arg; just exit if there's an error.  Revamp to follow
        POSIX 1003.2-1992 more precisely, to handle cases like "tail -
        file" and "tail -10 -- file" correctly when we are conforming to
        the older standard.
        (main): Adjust to this change.
        * tests/tail/Test.pm (test_vector): minus-* requires
        _POSIX2_VERSION=199209 now, to work correctly if there is
        an input file.  err-1 and err-3 no longer errors if there
        is another file.

2004-09-09  Paul Eggert  <eggert@cs.ucla.edu>

        * src/test.c (usage): Document -r, -w, -x more carefully.

2004-09-08  Paul Eggert  <eggert@cs.ucla.edu>

        * src/test.c (usage): Document "test" (with no args) and "[ ]".
        Document that -h and -L don't dereference.

        * NEWS: Document that "tr xy -z" now works as per POSIX.
        Sort the descriptions.
        * src/tr.c (main): Don't reorder options.
        * tests/tr/Test.pm (fowler-1): New test case.

2004-09-06  Paul Eggert  <eggert@cs.ucla.edu>

        * src/touch.c (main): Fix POSIX-conformance bug: "touch --
        MMDDhhmm file" must be treated like "touch MMDDhhmm file" when
        conforming to pre-2001 POSIX.
        * NEWS: Document this.
        * tests/touch/obsolescent: Test for this bug.  Also, set
        _POSIX2_VERSION=199209 and POSIXLY_CORRECT=1 so that it's
        a better test for obsolescent features.

        * src/sort.c (main): Emulate Solaris 8 and 9 "sort -y", so that
        "sort -y abc" is like "sort abc" whereas "sort -y 100" is like
        plain "sort".

        * src/od.c: Several changes for POSIX and FreeBSD compatibility.
        (COMMON_SHORT_OPTIONS): Add -B, -D, -e, -F, -H, -I, -L, -O, -s, -X.
        (long_options, main): --strings is now -S, not -s.
        (usage): Reflect the usage changes.
        (parse_old_offset): Do not issue a diagnostic on failure;
        callers now do this as necessary.
        (main): Support POSIX syntax.  Remove unused case 0 from getopt_long.
        Add support for new short options (many undocumented) for
        compatibility with FreeBSD.  Remove FIXME for -s; it's now
        POSIX-compatible.  Default format is now oS, not o2.
        * NEWS: Describe the above.

2004-09-05  Paul Eggert  <eggert@cs.ucla.edu>

        * src/stty.c (valid_options): Remove.
        (main): Fix some bugs in handling invalid option-combinations
        like "stty -F".
        (recover_mode): Arg is now char const *, not char *.
        (main): Use STDIN_FILENO, not 0.
        Simplify option-parsing code a tad.
        * tests/stty/basic-1: Check for the fixed bugs.

2004-09-03  Paul Eggert  <eggert@cs.ucla.edu>

        * src/stat.c (HAVE_STRUCT_STATXFS_F_TYPE): Fix typo that prevented
        it from ever being nonzero.  Reported by Pozsar Balazs in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00189.html
        (human_fstype): Add ramfs, squashfs, sysfs.
        Reported by Pozsar Balazs in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00188.html
        (human_fstype): Return char const *, not char *.
        Simplify internals a bit, and avoid casts.

        * src/dd.c (usage): "alternated EBCDIC" -> "alternate EBCDIC".
        (bit_count): Remove.  All uses changed to....
        (multiple_bits_set): New function.
        (scanargs): Use it, and check separately for each set of
        incompatible options, to improve diagnostics.
        (MX): Remove.
        (apply_translations): Move checks for incompatible options
        to scanargs, so that they're done consistently.

2004-09-02  Paul Eggert  <eggert@cs.ucla.edu>

        Output correct errno-related diagnostic on "paste" I/O errors.
        * src/paste.c (write_error, xputchar): New functions.
        (paste_parallel): Use correct errno value after input error.
        (paste_parallel, paste_serial): Report errno value after output error.

        Port to diet libc.  Problem reported by Felix von Leitner in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00171.html
        * src/paste.c (dummy_closed, CLOSED, dummy_endlist, ENDLIST): Remove;
        it's not portable C to assume FILE is a complete type.
        (paste_parallel): Use index test instead of ENDLIST, and NULL
        instead of CLOSED.

2004-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        POSIX-conformance fixes for "expand" and "unexpand".
        Also, consistently use "tab stop" rather than "tabstop".
        * NEWS: Document fixes.
        * src/expand.c: Revamp to resemble the new unexpand.c better.
        (usage): -i does not convert tabs after non-tabs.
        (add_tab_stop): Renamed from add_tabstop.  All uses changed.
        (parse_tab_stop): Renamed from parse_tabstop.  All uses changed.
        (validate_tab_stop): Renamed from validate_tabstop.  All uses changed.
        (next_file, main): Check fclose against 0, not EOF.
        (expand): Remove unnecessary casts.
        Add another loop nesting level, for lines, so that per-line variables
        are initialized cleanly.
        Revamp tab checking.  Check for write error immediately, rather
        than just once at the end of the program.
        * src/unexpand.c: Lkewise (for the expand.c changes).
        (TAB_STOP_SENTINEL): Remove.
        (tab_size): Now size_t, not uintmax_t, since we need to store
        the sequences of blanks.
        (max_column_width): New var.
        (usage): Say "blank" where POSIX requires this.
        (add_tab_stop): Calculate maximum column width.
        (unexpand): Store the pending blanks, instead of merely counting them.
        Follow POSIX's rules about -a requiring two blanks before a tab stop.
        Get rid of internal label and goto.
        * tests/unexpand/basic-1: Fix infloop-3 to match POSIX.
        Add blanks-1 through blanks-13.

2004-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: "chown : file", "chown '' file", and "chgrp '' file" now
        succeed without changing the uid and gid, like FreeBSD.
        * src/chgrp.c (parse_group): Return gid_t rather than storing it
        through a pointer.  Treat "chgrp '' file" as a no-op change,
        as FreeBSD does.
        (main): Set chopt.group_name to NULL if the group is the empty
        string.
        * src/chown-core.c (describe_change): Describe changes to -1:-1
        without using "to OWNERSHIP" phrase.
        * src/chown.c (usage): "chown '' file" is now allowed.
        (main): Do not set user name to the empty string if the group
        name is null.
        * tests/chgrp/basic: Test "chgrp '' file".
        * tests/chown/Makefile.am (TESTS): Add separator.
        * tests/chown/separator: New file, partly taken from
        Dmitry V. Levin's suggestion in
        <http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00102.html>

2004-08-11  Paul Eggert  <eggert@cs.ucla.edu>

        * tests/install/basic-1: Test for the -d regression.

2004-08-11  Dmitry V. Levin  <ldv@altlinux.org>

        * src/install.c (main): Fix -d regression introduced with
        --target-directory support at 2004-06-25.

2004-08-11  Paul Eggert  <eggert@cs.ucla.edu>

        * src/copy.c (copy_internal): When preserving links, unlink
        a destination with link count greater than one.  This is so
        that commands like "cp -a" don't get confused when copying into
        a destination that already contains many hard links.  Problem
        reported by Tim Waugh in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00053.html

2004-08-10  Paul Eggert  <eggert@cs.ucla.edu>

        * tests/uniq/Test.pm (8): Likewise.
        * tests/misc/printf-hex: Use ASCII, not Latin-1.

        * NEWS: Document "sort -o -" and "tee -" POSIX-conformance fixes.
        * src/shred.c (usage): "-" is an operand, not an option.
        * src/sort.c (die, xfopen, mergefps, first_same_file, merge):
        A null file arg means standard output.
        (main): "-o -" means to write to a file named "-",
        not to standard output.
        * src/tee.c (usage, tee): "tee -" writes to standard output, not
        to a file named "-".

2004-08-10  Dmitry V. Levin  <ldv@altlinux.org>

        * src/install.c (change_timestamps): Fix int->bool conversion
        bugs introduced on 2004-07-29.

2004-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        * src/shred.c (wipename): Work even if the directory is writeable
        and not readable.  Prefer write access, since this should work
        better with fdatasync.

        * src/csplit.c (xalloc_die): New function.
        (main): Remove now-obsolete initialization of xalloc_fail_func.

        * src/md5sum.c: Adjust to sha->sha1 renaming.

2004-08-08  Dmitry V. Levin  <ldv@altlinux.org>

        Minor code cleanup.

        (can_mode): Make variable local.

2004-08-07  Paul Eggert  <eggert@cs.ucla.edu>

        * src/system.h (O_BINARY) [!O_BINARY && defined O_BINARY]:
        Do not define, to avoid annoying compiler messages on QNX 6.3.
        Problem reported by Johan in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00050.html

2004-08-04  Paul Eggert  <eggert@cs.ucla.edu>

        * src/system.h (PRIdMAX, PRIoMAX, PRIuMAX, PRIxMAX):
        Define to a concatenation of string literals, not to an expression;
        needed for concatenation contexts.
        (INTMAX_MAX, INTMAX_MIN): New macros.

        * src/stat.c (print_stat): Don't assume st_ino / st_dev fits in
        unsigned long; this isn't true for st_ino on Solaris 9.

2004-08-03  Paul Eggert  <eggert@cs.ucla.edu>

        * src/uname.c: Do not depend on HAVE_SYSCTL when deciding
        whether to include files.  Include <sys/param.h> if
        HAVE_SYS_PARAM_H (not HAVE_SYSCTL).
        (main) [defined __POWERPC__]: Add a kludge to work around a
        Mac OS X bug, so that uname -p defaults to "powerpc" if

        unsigned int.

        * src/unexpand.c: Int cleanup and minor reorganization to be more
        like src/expand.c.
        Include quote.h, xstrndup.h.
        (TAB_STOP_SENTINEL): Increase from INT_MAX to INTMAX_MAX.

        three_arguments, posixtest, expr, term, and, or, is_int, age_of,
        one_argument, main): Use bool for booleans.
        (advance, unary_advance): Now inline procedures rather than a macros.

        merely because its mode&S_IFMT is zero.  Just use S_ISREG.
        Remove unnecessary casts.  Remove ifdefs for things like
        S_ISSOCK that are no longer needed, since stat-macros.h always
        defines them now.

        calculations.
        (main): Remove unnecessary casts.

        * src/su.c (run_shell): Pass a new n_additional_args arg, so that
        the callee doesn't have to count 'em.  All callers changed.
        Don't allocate more space for the arg vector than we'll need.
        Use memcpy to copy the args rather than rolling our own loop.

        has an indefinite lifetime.
        (modify_environment): Allocate a larger environ.
        (main): Remove an impossible 'case 0'; if it happens now, it'll
        get diagnosed.  Don't assume getpwnam results outlive endpwent.
        Check for null or empty pw_name, pw_dir and for null pw_passwd.

        * src/stty.c (VA_START): Remove.  All callers now use va_start.

        (struct control_info): Use size_t for sizes.

        Use bool for booleans.
        (integer_arg): Return unsigned long int, not long int.
        Accept new max arg; all callers changed, to specify a maximum
        value for integer parameters instead of silently overflowing.

        elements are always chars.
        (first_last_page, main, getoptarg, balance, add_line_number,
        char_to_uclump): Remove unnecessary casts.

        * src/printenv.c (main): Use bool for booleans.
        Do not assume that the environ has at most one matching entry
        for each option (integer overflow was possible otherwise).

        * src/od.c (FMT_BYTES_ALLOCATED): Now an enum, not a decimal
        constant.  Do not assume PRIdMAX etc. are strings of length 3 or
        less.
        (struct tspec): Use it.  fmt_string is now an array, not
        a pointer, as there's little point to the indirection here.

        bytes_to_unsigned_dec_digits, bytes_to_hex_digits):
        Use char, not unsigned int, since char suffices.

        print_int, print_long, print_long_long, print_float,
        print_double, print_long_double): Rewrite to avoid casts.
        These now take void * arguments, instead of char *.
        Use the same body for all functions, except for the choice
        of type.  Assume C89 to simplify handling of signed char.
        (dump_hexl_mode_trailer, print_named_ascii, print_ascii):
        Rewrite to avoid casts.
        (print_named_ascii, print_ascii): Now takes void *, not char *.
        (decode_one_format): Use int for printf field widths, not
        unsigned int.  Pass void * to subsidiary printers,
        not char *.  Simplify handling of floating-point formats
        by factoring out common code dealing with precision and field width.
        (decode_format_string): Avoid need for temporary copy of
        each decoded struct tspec.
        (get_lcm): Remove unnecessary cast.

        for state counters.
        (tail_bytes, tail_lines): Redo test of return value (-1, 0, 1) to
        make it a bit clearer.

        * src/hostname.c: Include "xgethostname.h".
        (xgethostname): Remove decl; xgethostname.h has it.
        (sethostname) [!defined(HAVE_SETHOSTNAME) && defined(HAVE_SYSINFO)
        && defined (HAVE_SYS_SYSTEMINFO_H) && defined(HAVE_LIMITS_H)]: Use
        prototypes rather than K&R form.  Assume any negative value from
        sysinfo denotes failure, not just -1.
        (main): Simplify use of sethostname.

        * src/pinky.c (include_idle, include_heading, include_fullname,
        include_project, include_plan, include_home_and_shell, do_short_format,
        include_where, main): Use bool for booleans.
        (count_ampersands, create_fullname, scan_entries, short_pinky):
        Use size_t for sizes.
        (create_fullname): Check for overflow in size calculations.
        (idle_string): Don't assume that the number of idle days
        is less than 10**8 and/or INT_MAX/(24*60*60).
        (main): No need to pass a non-NULL last arg to getopt_long.
        * src/uptime.c (print_uptime, uptime): Use size_t for sizes.
        (print_uptime): Remove unused local variable.
        (main): No need to pass a non-NULL last arg to getopt_long.
        * src/users.c (list_entries_users, users): Use size_t for sizes.
        (list_entries_users): Use char for bytes.
        (main): No need to pass a non-NULL last arg to getopt_long.
        * src/who.c (do_lookup, short_list, short_output, include_idle,
        include_heading, include_mesg, include_exit, need_boottime,
        need_deadprocs, need_login, need_initspawn, need_clockchange,
        need_runlevel, need_users, my_line_only, main): Use bool for booleans.
        (print_runlevel): Use unsigned char for bytes.
        (list_entries_who, scan_entries, who): Use size_t for sizes.
        (main): No need to pass a non-NULL last arg to getopt_long.

        * src/install.c (isdir): Remove decl.
        (install_file_to_path): Rely on make_path to fail if the destination
        is not a directory, by passing preserve_existing==true to it.
        Hence we no longer need to call isdir.
        Free dest_dir immediately when it's no longer needed, rather than
        waiting until the end of the function.
        (copy_file): Don't bother calling isdir, as copy will do the
        right thing if the destination is a directory.

        * src/du.c (fts_debug, opt_all, apparent_size, opt_count_all,
        print_grand_total, opt_separate_dirs, hash_ins, process_file, main):
        Use bool for booleans.
        (max_depth): Now size_t, not int, to avoid an arbitrary limit
        of INT_MAX on depth.
        (G_fail): Remove: no longer needed, now that the relevant
        functions return bool.
        (process_file): Use return value to signal success rather than
        setting a global.  Remove first_call static var; not needed, since
        we can look at n_alloc.  Use size_t for depths.  Remove FIXME
        about size_t casts, as it's now fixed.  Use xnrealloc rather
        than the obsolescent XREALLOC.  Don't bother to check whether
        reallocation is needed unless level > prev_level.
        (du_files): Invert sense of result, for consistency with
        other coreutils code.  All callers changed.
        (main): Allow --max-depth values up to SIZE_MAX.

        * src/df.c (inode_format, show_all_fs, show_local_fs,
        show_listed_fs, posix_format, require_sync, print_type,
        selected_fstype, excluded_fstype, show_dev, show_point, main):
        Use bool for booleans.
        (df_readable, show_dev): Use UINTMAX_MAX instead of -1.
        (show_dev, show_point, main):
        Use EXIT_SUCCESS/EXIT_FAILURE instead of 0/1.
        Don't assume disk name lengths are <= INT_MAX.
        Rewrite pct calculation to avoid cast.
        (show_point): Don't assume resolved length is <= SSIZE_MAX.

        * src/cut.c (hash_int) [!defined UINTPTR_MAX]: Use size_t
        instead of uintptr_t.
        * src/shred.c (UINT_MAX_32_BITS): Remove.
        (word32): Remove.  All uses changed to uint32_t.
        (isaac_seed_data): Remove unnecessary cast.
        * src/system.h (ptr_align): Use size_t; in practice, this is just as
        good as uintptr_t in checking for alignments, and has fewer
        configuration hassles.

        * src/Makefile.am (localedir.h): Make it readonly; this
        undoes part of the 2004-07-27 patch.

2004-07-30  Paul Eggert  <eggert@cs.ucla.edu>

        * src/sort.c (UCHAR): Remove; all uses changed to to_uchar.
        (IS_THOUSANDS_SEP): Use bool when appropriate.
        (numcompare, main): Use char, not int, when the value is always a char.
        (numcompare): Remove "register"; compilers are smart enough these days.
        * src/system.h (errno, CHAR_BIT): Remove decls;
        no longer needed now we assume C89 or better.
        Include <inttypes.h> before <stdint.h>, as it's the
        Autoconf-recommended pattern.
        (to_uchar): New inline function, moved here from tr.c.
        Use full names for int types, e.g. "long int" rather than "long".
        * src/tr.c (to_uchar): Remove; now in system.h.
        (is_char_class_member): Use bool when appropriate.

        * src/mkdir.c (create_parents, main): Use bool when appropriate.
        (main): Use EXIT_SUCCESS/EXIT_FAILURE instead of 0/1.

2004-07-29  Paul Eggert  <eggert@cs.ucla.edu>

        * src/mkfifo.c (main): Use EXIT_SUCCESS and EXIT_FAILURE, not 0 and 1.

        * src/chmod.c (recurse, force_silent, process_file, process_files,
        main): Use bool when appropriate.
        * src/cksum.c (cksum, main): Likewise.
        * src/comm.c (hard_LC_COLLATE, only_file_1, only_file_2, both,
        compare_files, main): Likewise.

        * src/copy.h (struct cp_options): Likewise.
        * src/copy.c (copy_internal, is_ancestor, copy_dir, copy_reg,
        same_file_ok, seen_file, copy_internal, valid_options, copy): Likewise.
        * src/cp-hash.h (remember_created): Likewise.
        * src/cp-hash.c (remember_created): Likewise.
        * src/cp.c (struct dir_attr, flag_path, remove_trailing_slashes,
        re_protect, make_path_private, target_directory_operand, do_copy,
        cp_option_init, decode_preserve_arg, main): Likewise.
        * src/install.c (isdir, change_timestamps, change_attributes,
        copy_file, install_file_to_path, install_file_in_dir,
        install_file_in_file, strip_files, dir_arg, cp_option_init, main,
        change_attributes, change_timestamps): Likewise.
        * src/mv.c (remove_trailing_slashes, rm_option_init,
        cp_option_init, do_move, movefile, main): Likewise.
        * src/remove.c (right_justify), full_filename_, AD_pop_and_chdir,
        AD_push, prompt, remove_dir): Likewise.
        * src/rm.c (rm_option_init, main): Likewise.

        * src/remove.c (top_dir, pop_dir, full_filename_):
        Use size_t for sizes.
        * src/cp.c (target_directory_operand): Do not clear *NEW_DST if stat
        succeeds.  It's not necessary in that case, as *NEW_DST is always
        false already.
        (do_copy): Rewrite slightly to avoid need for "unreachable" comment.
        (main): Use EXIT_SUCCESS, EXIT_FAILURE instead of 0, 1.
        * src/rm.c (main): Likewise.

        md5sum, sha1sum integer cleanups.

        * src/checksum.h: Don't include config.h, sys/types.h, stdio.h:
        not needed.
        (ALG_UNSPECIFIED): Remove.
        (ALG_MDT): Don't make it equal to CHAR_MAX + 1; this isn't necessary.
        * src/md5.c: Don't include any files other than checksum.h.
        * src/sha1sum.c: Likewise.
        * src/md5sum.c (OPENOPTS, have_read_stdin, status_only, warn,
        bsd_split_3, split_3, hex_digits, digest_file, digest_check, main):
        Use bool when appropriate.
        (digest_check): Increase limit of number of input lines to
        UINTMAX_MAX from INT_MAX.  Diagnose any overflows of this counter.
        Use ngettext instead of hard-to-i18nize hardcoded stuff for plurals.

2004-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        * src/cat.c (exit_status): Remove.  Now done by passing a boolean
        'ok' flag around.
        (simple_cat, cat): Return true if successful.  All callers changed.
        (simple_cat, cat, main): Use bool for booleans.
        (simple_cat): Use size_t for sizes.
        (cat, main): Use the same names for parameters that we use for
        long options, to avoid confusion.  This inverts the sense of the
        show_tabs (formerly output_tabs) and number_nonblank
        (formerly numbers_at_empty_lines) variables.
        (main): Don't mess up (due to integer overflow) if we are given
        INT_MAX - INT_MIN + 1 options.
        [O_BINARY]: Don't invoke isatty unless the other options require it.
        (main): When deciding whether to use simple_cat, don't worry
        about binary option; it's irrelevant.

        * src/dcgen: Remove comments, trailing white space, and empty
        lines from the output strings, to save space.
        Use a narrower type like 'unsigned char' for line lengths, if
        that will do.
        Make the output variables static, not extern.

        * src/chgrp.c (parse_group): Require base 10 when parsing
        groups as integers.
        (main): int -> bool when appropriate.
        * src/chown.c (main): Likewise.
        * src/chown-core.c: Include inttostr.h.
        (UINT_MAX_DECIMAL_DIGITS, uint_to_string): Remove.
        (gid_to_name, uid_to_name): Use imaxtostr/umaxtostr
        instead of uint_to_string).
        (describe_change): Instead of an int flag, use a char *
        auxiliary; this avoids the need for casts.
        Assume free (NULL) works.
        (change_file_owner): Return true/false, not 0/-1, since
        we don't set errno.  All callers changed.
        Use bool when appropriate.
        (chown_files): Likewise.
        * src/chown-core.h (chown_files): Likewise.

        * tests/chown/basic: Test for proper handling of uids like
        "010", which must be parsed as decimal.

        * tests/misc/pwd: Don't assume that Perl's getpwd agrees with our
        pwd when there are multiple names for the working directory
        (which can happen with an automounter, sigh).

        * src/Makefile.am ($(SCRIPTS)): Don't depend on Makefile;
        this causes Solaris 8 'make' to refuse to build "groups".
        (localedir.h): Don't depend on Makefile: this causes Solaris
        8 'make' to build localedir.h unnecessarily.  The dependence
        on Makefile is ineffective anyway, since $(localedir) might
        change even if Makefile hasn't.

        * src/remove.c (remove_dir): If we can't save the state of the
        working directory, pretend we started from "/", not ".".
        This avoids a bug on hosts like Solaris that don't let you
        remove the working directory.

2004-07-27  Paul Eggert  <eggert@cs.ucla.edu>

        * src/printf.c (strtiomax, strtoumax): Declare if not already
        declared: this fixes a portability bug with Solaris 8 + GCC.
        (STRTOX): Parenthesize use of macro arg as expression.
        (vstrtoimax, vstrtoumax, vstrtold): Remove now-unnecessary
        parentheses.
        * configure.ac: Check for declaration of strtoumax, for
        src/printf.c.

        * src/Makefile.am (cp_LDADD, ginstall_LDADD, mv_LDADD,
        pathchk_LDADD, rm_LDADD, test_LDADD): New vars, for eaccess.

        * tests/readlink/can-e: Don't assume that we can remove the
        working directory: this isn't possible under Solaris 8, say.
        * tests/readlink/can-f: Likewise.
        * tests/readlink/can-m: Likewise.

        * src/copy.c (copy_internal): find_backup_file_name no longer
        returns NULL, so don't bother to check for this.
        * src/cp.c (do_copy): Likewise.
        * src/ln.c (do_link): Likewise.

2004-07-25  Paul Eggert  <eggert@cs.ucla.edu>

        * src/nice.c (GET_NICE_VALUE): Renamed from GET_PRIORITY.
        All uses changed.
        (NZERO): New macro, if system doesn't define it already.
        (usage): Distinguish priorities from nice values.
        Don't assume NZERO is 20.
        (main): Use bool instead of int where appropriate.
        If user specifies an adjustment out of range, always truncate it
        to an inrange value instead of sometimes giving an error message
        and sometimes not.
        Do not assume that -1 is an error return from "nice" or
        "getpriority", as it might be the current nice value minus NZERO.
        If nice/setpriority fails with errno == EPERM, go ahead and run
        the command anyway; POSIX requires this.

        * src/pathchk.c: Include euidaccess.h.
        (dir_ok): Use euidaccess, not access.
        * src/test.c (R_OK, W_OK, X_OK, FOK): Remove; system.h defines them.
        (eaccess): Remove.  All users changed to use euidaccess instead.

2004-07-24  Paul Eggert  <eggert@cs.ucla.edu>

        * src/uptime.c (print_uptime) [defined BOOT_MSG]:
        Don't assume ut_line is null-terminated.
        * src/who.c (print_line): New arguments USERLEN and LINELEN,
        since USER and LINE might not be null terminated.  All callers
        changed.

2004-07-23  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug with "tail -f" reported by Rob Holland in
        <http://lists.gnu.org/archive/html/bug-coreutils/2004-07/msg00054.html>.
        Also, remove the undocumented and unsupported-since-2000
        --max-consecutive-size-changes options.  Fix another related bug:
        "tail" got confused if stdin, stdout, or stderr were closed.
        Also, use output buffering even with "tail -f".

        * NEWS: Document this, plus yesterday's patch.
        * doc/coreutils.texi (tail invocation): "size has remained the same"
        -> "file has not changed", which is more accurate for fifos.
        * src/tail.c: Include fcntl-safer.h.
        (COPY_TO_EOF): Set to UINTMAX_MAX, not OFF_T_MAX (which was wrong).
        (COPY_A_BUFFER): New macro.
        (struct File_spec): New members mtime, mode, blocking.
        Remove member n_consecutive_size_changes.
        (DEFAULT_MAX_N_CONSECUTIVE_SIZE_CHANGES,
        max_n_consecutive_size_changes_between_opens,
        MAX_CONSECUTIVE_SIZE_CHANGES_OPTION): Remove.
        (long_options, tail_forever, parse_options):
        Remove (non-)support for --max-consecutive-size-changes.
        (record_open_fd): New function.
        (recheck, tail_file): Use it.  Don't assume that stdin is open.
        (dump_remainder): Add support for new COPY_A_BUFFER special value.
        Treat errno==EAGAIN like EOF, since it might be a nonblocking read.
        (recheck): New arg BLOCKING, specifying whether to use blocking reads.
        All uses changed.
        (n_live_files): Remove, replacing with...
        (any_live_files): New function.  All uses changed.
        (tail_forever): Use nonblocking I/O unless we know that blocking I/O
        is safe; this avoids some hangs when reading from a fifo.
        Avoid invoking fstat or sleep when using blocking I/O.
        Do not check for changes to size if the file is not a regular file,
        as the size is undefined in that case.
        Check for changes to mtime or mode, too; this works for non-regular
        files.
        (tail_forever, main): Redo fflush strategy to work even when input
        is nonblocking.  Don't use unbuffered output; just flush when needed.

2004-07-22  Paul Eggert  <eggert@cs.ucla.edu>

        * src/tail.c (main): Ignore -f if no file operand is specified
        and standard input is a pipe.
        * doc/coreutils.texi (tail invocation): Do not ignore -f for
        all pipes, just for when standard input is a pipe and no
        file operand is specified.
        * tests/tail/Test.pm: Reinstate f-1 test, since we now pass.
        Add a new commented-out f-2 test, which we still fail.
        (test_vector): All f-* tests are special cases, not just f-1.

2004-07-12  Paul Eggert  <eggert@cs.ucla.edu>

        * src/uptime.c: Include c-strtod.h.
        (print_uptime): Use c_strtod instead of setlocale and sscanf.
        Use long int rather than int to count days (for 64-bit hosts),
        and check for arithmetic overflow when converting double to time_t.

2004-07-11  Paul Eggert  <eggert@cs.ucla.edu>

        * src/printf.c (vstrtold): Renamed from vstrtod.
        Now returns long double.  All uses changed.
        (print_direc): Use "L" length modifier when printing floating point
        numbers, since we're now printing long double.

2004-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        printf cleanup, to avoid undefined behavior, to add support for
        formats that Bash supports, and to support wide integers like
        Bash does.

        * NEWS: Document this.
        * src/printf.c (UNSPECIFIED): Remove.  All uses now replaced by
        booleans, so that we don't reserve any values for precision or
        width (like Bash).
        (STRTOX): Use prototype, not K&R-style definition.
        (vstrtoimax): Renamed from xstrtol (to avoid confusion with xstrtol
        in ../lib), with type change to intmax_t.
        All uses changed.
        (vstrtoumax): Renamed from xstrtoul, with type change to uintmax_t.
        All uses changed.
        (vstrtod): Renamed from xstrtod.  All uses changed.
        (print_direc): Use boolean arg instead of special value to indicate
        a missing precision or width.  LENGTH no longer includes
        length modifiers or conversion character.  New arg CONVERSION
        now specifies conversion character.
        Use intmax_t-width formatting for integers (like Bash).
        Add support for C99 %a, %A, %F (like Bash).
        Add support for field width with %c (POSIX requires this).
        Add a FIXME for lack of support for field width and precision
        for %b.
        Add support for '\'', '0' flags.
        Check for invalid combinations of flags, field width, precision,
        and conversion, to prevent use of undefined behavior.
        Allow multiple length modifiers, for formats like "%lld" (like Bash).
        Add support for C99 'j', 't', 'z' length modifiers (like Bash).
        In error message, output entire invalid conversion specification,
        instead of merely outputting % followed by the conversion char.
        * tests/misc/printf: Add tests for the above.

2004-04-03  Dmitry V. Levin  <ldv@altlinux.org>

        Change "readlink -f" to be more compatible with prior implementations.
        Add more canonicalize options, -e and -m.
        Add comprehensive tests for all readlink modes.

        * m4/canonicalize.m4 (AC_FUNC_CANONICALIZE_FILE_NAME):
        Do not add canonicalize.c here.

        * src/readlink.c (longopts): Add new options.
        (usage): Document them.
        (canonicalize_fname): New proxy function.
        (main): Handle new options.
        * doc/coreutils.texi (readlink invocation): Document new
        "readlink -f" behaviour and new canonicalize options, -e and -m.

        * configure.ac (AC_CONFIG_FILES): Add tests/readlink/Makefile.
        * tests/Makefile.am (SUBDIRS): Add readlink.
        * tests/readlink/Makefile.am: New file.
        * tests/readlink/{rl-1,can-e,can-f,can-m}: New readlink tests.
        * tests/misc/Makefile.am (TESTS): Remove basic readlink test.
        * tests/misc/readlink: Remove file.

2004-07-04  Jim Meyering  <jim@meyering.net>

        * src/copy.c (copy_internal): Add a FIXME comment.

2004-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * src/cp.c (do_copy): Likewise.
        * src/mv.c (movefile): Likewise.

        * src/cp.c (make_path_private): 2nd arg is now size_t, not int,
        to avoid problem when path_concat dir name is longer than 2 GiB (!).

        * src/nohup.c (main): Don't pass NULL first argument to path_concat.
        This cleans up the semantics a bit, as we no longer try to open the
        same file twice.

2004-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Add short names -t and -T for --target-directory
        and --no-target-directory options, respectively.

        * src/cp.c (NO_TARGET_DIRECTORY_OPTION, TARGET_DIRECTORY_OPTION):
        Remove.  All uses changed to 'T' and 't', respectively.

        * src/cp.c (long_opts, usage, do_copy, main): Add -t and -T as
        aliases for --target-directory and --no-target-directory,
        respectively.
        * src/install.c (long_options, main, usage): Likewise.

2004-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        * src/stat.c (usage): Likewise.

        reasons.

2004-06-29  Paul Eggert  <eggert@cs.ucla.edu>

        Add support for --no-target-directory option.

        * NEWS: Document it.

        invocation, install invocation, mv invocation, ln invocation):
        Likewise.
        (link invocation): Explain how to rewrite link using ln now
        that we have --no-target-directory.
        (ln invocation): Explain that --no-target-directory subsumes
        --no-dereference.
        (unlink invocation): Modify wording to match new wording in
        link invocation.

        * src/cp.c (NO_TARGET_DIRECTORY_OPTION): New constant.

2004-06-25  Paul Eggert  <eggert@cs.ucla.edu>

        Add support for 'install --target-directory', an option
        that has been documented for years but not implemented (!).
        * doc/coreutils.texi (install invocation): Document
        --target-directory in synopsis, too.
        * src/install.c (TARGET_DIRECTORY_OPTION): New var.
        (long_options, main, usage): Add --target-directory.
        (target_directory_operand): New function, stolen from mv.c.
        (main): Use it.  Check for -d and --target-directory.
        Alter wording of diagnostics to match other programs.

2004-06-28  Jim Meyering  <jim@meyering.net>

        * src/cp.c (usage): Fix copy+paste error in description of
        --target-directory: s/move/copy/.  From Paul Jarc.

2004-06-27  Paul Eggert  <eggert@cs.ucla.edu>

        Use more-consistent rules among cp, ln, and mv when dealing with
        last operands that are (or look like) directories.

        * src/cp.c (target_directory_operand): New, nearly-common function,
        It reports an error if the destination appears to be a directory
        (e.g., because it has a trailing slash) but is not.
        * src/ln.c, src/mv.c: Likewise.
        * src/cp.c (do_copy): Use it.
        * src/ln.c (main): Likewise.
        * src/mv.c (main): Likewise.

        * src/cp.c (do_copy): Don't assume argc is positive.
        Don't bother to lstat dest, since copy() will do that for us.
        Use "const" to avoid the need for cast.

        * src/cp.c (do_copy): Don't output a usage message because of file
        problems (e.g., an operand is not a directory).  Use it only for
        syntax.  Standardize on "target %s is not a directory" for the
        diagnostic.
        * src/ln.c (main): Likewise.
        * src/mv.c (main): Likewise.

        * src/cp.c (do_copy): Remove test for trailing slash, since
        target_directory_operand now does this.
        * src/ln.c (main): Likewise.
        * src/mv.c (movefile): Likewise.

        * src/cp.c (main): Reject multiple target directories.
        Check whether a specified target is a directory when parsing the
        options, using stat.  This gives more-accurate diagnostics.
        * src/ln.c (main): Likewise.

        * src/ln.c (isdir): Remove decl; no longer needed.
        * src/mv.c (isdir, lstat): Likewise.

        * src/ln.c (do_link): New arg dest_is_dir.  All uses changed.
        Don't check the destination ourself; rely on dest_is_dir.
        This way we can avoid lstatting the destination in the
        usual case, and in the worst case we lstat 1, not 3 times.
        Don't bother to unlink unless link failed; this saves a syscall.
        Remove unnecessary backup_succeeded flag;
        it was identical to "dest_backup != NULL".

        * src/ln.c (main): Use int to count to argc, not unsigned int.
        This handles negative operand counts.
        * src/mv.c (main): Likewise.

        * src/mv.c (do_move): Don't call hash_init; expect the caller to
        do it, for consistency with cp.c and ln.c.  All callers changed.
        (movefile): dest_is_dir parameter is now bool, not int.
        (main): Standardize on "missing destination file operand after %s"
        for the diagnostic, for consistency with cp.c.

        * tests/mv/diag: Don't assume "mv --target=nonexistentdir"
        will complain about the arg count.
        Adjust to new (briefer) diagnostics.
        * tests/cp/fail-perm: Add a test to verify that we get the new
        diagnostic when failing to copy through a symlink-to-inaccessible-dir.

2004-06-27  Paul Eggert  <eggert@cs.ucla.edu>

        Fix a bug: formerly, if d/x was a directory and x a file, "ln x
        d/" incorrectly created a link d/x/x.  It also saves some system
        calls.

        * NEWS: Document the fix.

        * src/ln.c (main): Don't append basename to dest if this
        results in an existing directory name.
        * tests/ln/misc: See whether a trailing slash is followed too far.

2004-06-26  Jim Meyering  <jim@meyering.net>

        * src/printf.c (main): When given no arguments, print the standard
        "missing operand\nTry printf --help..." message -- to be consistent.

2004-06-26  Jim Meyering  <jim@meyering.net>

        * src/mknod.c (main): Add \n at the end of message output via fprintf.

2004-06-25  Jim Meyering  <jim@meyering.net>

        * tests/ln/misc: Add test for ln subscript error.

2004-06-23  Paul Eggert  <eggert@cs.ucla.edu>

        * src/ln.c (do_link): Remove unnecessary call to lstat.
        (main): Avoid subscript error when the destination is "".

2004-06-23  Jim Meyering  <jim@meyering.net>

        * tests/*: Replace all occurrences of `(exit N); exit' with
        `(exit N); exit N'.  Otherwise, those many tests could exit with
        improper exit status when exiting via e.g., a trapped interrupt.
        Thanks to a report from Bob Proulx.

2004-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        * src/who.c (idle_string, print_user): New arg boottime,
        specifying the most recent boot time.  All uses changed.
        (idle_string) Consider a line to be "old" if it hasn't been used
        since the last boot time.  Watch out for overflow when computing
        times, and for times in the future.
        (idle_string): Record latest boot time.

2004-06-22  Jim Meyering  <jim@meyering.net>

        * src/test.c (usage): Correct description of `-t FD'.  The file
        descriptor, FD, is no longer optional.  Reported by Ton Nijkes.

2004-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        The 2004-06-19 fix for who and pinky was incomplete, as ctime
        has undefined behavior if the year precedes -999 or follows 9999.
        Since we have to stop using ctime anyway, we might as well use
        strftime and fix the FIXME, and support internationalized dates.

        * NEWS: Document the new behavior.
        * src/who.c: Include "hard-locale.h".
        (time_format, time_format_width): New vars.
        (time_string, print_line): Use them.
        (main): Set them.
        (time_string): Use localtime + strftime instead of
        ctime, to avoid problems with years before -999 or after 9999.
        * src/pinky.c: Likewise.

2004-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug: GNU 'ls' didn't count columns correctly if user or group
        names contained multibyte characters where the column count
        differed from the byte count.  This patch also corrects
        some comments.

        * src/ls.c (format_user_or_group): New function, which counts
        columns correctly.
        (format_user, format_group): Use it.
        (format_user_or_group_width): New function, which counts columns
        correctly.
        (format_user_width, format_group_width): Use it.

2004-06-21  Jim Meyering  <jim@meyering.net>

        * tests/priv-check: Quote "$PATH" in PATH=$PATH.
        Suggestion from Andreas Schwab.

        * tests/priv-check: When running as root, be sure to propagate
        PATH through to the process we exec as non-root.
        Reported by michael@aplatform.com.

        * src/mknod.c (main): Don't segfault when calculating the
        expected number of operands for `mknod NAME'.

2004-06-20  Jim Meyering  <jim@meyering.net>

        * src/dd.c (input_seek_errno): Declare file-scoped variable as static.

2004-06-20  Paul Eggert  <eggert@cs.ucla.edu>

        * src/basename.c (main):
        Standardize on the diagnostics given when someone gives
        too few operands ("missing operand after `xxx'") or
        too many operands ("extra operand `xxx'").
        Include "quote.h" and/or "error.h" if it wasn't already being included.

2004-06-19  Jim Meyering  <jim@meyering.net>

        * src/system.h (case_GETOPT_VERSION_CHAR): Switch back to
        using GNU_PACKAGE (from PACKAGE) once again.  This restores
        `GNU' to the parenthesized package name in --version output.
        Before, the first argument from AC_INIT, `GNU coreutils', would
        be propagated to the PACKAGE variable.  Now, `GNU ' is trimmed.

2004-06-09  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Remove special cases for POSIXLY_CORRECT when POSIX allows
        the GNU behavior.
        * doc/coreutils.texi (pr invocation, unlink invocation): Document this.
        * src/ls.c (decode_switches): Pay attention to TABSIZE even if
        POSIXLY_CORRECT is set.  POSIX reserves upper-case environment
        variables to the implementation, so it's OK for ls to depend on
        TABSIZE.
        * src/pr.c: Include "hard-locale.h".
        (main): When in a non-POSIX locale, ignore POSIXLY_CORRECT, since
        POSIX specifies the behavior only in the POSIX locale.
        * src/printf.c (print_esc): Support \x, \u, \U even if POSIXLY_CORRECT,
        since POSIX says the behavior is unspecified here.
        * src/tail.c (parse_obsolescent_option): Support multiple file operands
        even if POSIXLY_CORRECT, since POSIX does not require a diagnostic.
        * src/printf.c (main): Recognize --help, --version even if
        POSIXLY_CORRECT.  POSIX does not specify any options, but it
        does not prohibit options either, so "printf" is like "expr" here.
        * src/unlink.c (main): Likewise.
        * tests/misc/printf: Adjust to the new semantics for \x if
        POSIXLY_CORRECT.

2004-06-14  Jim Meyering  <jim@meyering.net>

        * tests/misc/pwd: New test, for fix of 2004-04-19.

        (BUILD_SRC_DIR): Define BUILD_SRC_DIR.

        * src/copy.c: Remove declaration of euidaccess.
        Instead, include "euidaccess.h".

2004-06-13  Paul Eggert  <eggert@cs.ucla.edu>

        * src/who.c (PIDSTR_DECL_AND_INIT): Don't assume pid_t fits in int.
        (UT_ID) [!HAVE_STRUCT_XTMP_UT_ID]: Remove bogus comment,
        as (sizeof "??") reliably returns 3.
        (print_line): Guard against idle and pid being too long
        (which is possible when printing headers).
        (print_user): Allocate enough bytes for idlestr.  Use IDLESTR_LEN.
        Avoid unnecessary cast of sizeof to int.
        (make_id_equals_comment): Do not assume that UT_ID returns
        a string; it might return a non-null-terminated array.
        Use strncat instead.  It's not very often where strncat is
        exactly what you want, but this is one of those rare cases.

2004-06-11  Paul Eggert  <eggert@cs.ucla.edu>

        * src/who.c (list_entries_who): Don't output a trailing space.

2004-06-09  Jim Meyering  <jim@meyering.net>

        * src/touch.c (usage): Improve wording in description of the
        --time=WORD option.  Reported by Dan Jacobson.

        * src/chown-core.c (change_file_owner): Change names of parameters
        old_uid and old_gid to required_uid and required_gid respectively.

        * src/chmod.c (mode_changed): Return false, not 0, now that the
        function returns `bool'.

2004-06-08  Paul Eggert  <eggert@cs.ucla.edu>

        Adjust chmod and chown to be similar if -c or -v are given.  In
        particular, a no-op chown is no longer reported as a change; this
        reverts to previous behavior.  Also, fix both commands so that -v
        report failures even if the failure is not due to the chmod or
        chown syscalls.

        * src/chmod.c (CH_NOT_APPLIED): New constant.
        (describe_change): Handle it.
        (process_file): Use it, if a symlink wasn't changed.
        (mode_changed): Return bool, not int.  Accept new argument
        NEW_MODE; all callers changed.  This lets us avoid statting the
        file unless the new mode has unusual bits.
        (process_file): Return -1 on error.  With -v, report all errors
        verbosely, not just some.

        * src/chown-core.c (change_file_owner): Return -1 on error, not
        1 sometimes and -1 on others.  Our caller ORs together our results,
        and (-1 | 1) == 0 on ones-complement hosts.
        With -v report all errors verbosely, not just some.
        Fix bug when chopt->root_dev_ino && !chopt->affect_symlink_referent:
        file_stats wasn't set properly in that case.

        * tests/chgrp/basic: Adjust to above changes.

2004-05-20  Paul Eggert  <eggert@cs.ucla.edu>

        * tests/chgrp/basic: Test that chgrp -h does not fail on
        symlinks, even on hosts where that's not supported.
        Test that if -R is specified without -H or L, -h is assumed.
        Test that chown() is not optimized away.

2004-05-18  Paul Eggert  <eggert@cs.ucla.edu>

        Several fixes to chgrp and chown for compatibility with POSIX and BSD:

          Check for incompatible options.  When -R and --dereference are
          both used, then either -H or -L must also be used.  When -R and -h
          are both used, then -P must be in effect.

          -H, -L, and -P have no effect unless -R is also specified.
          If -P and -R are both specified, -h is assumed.

          Do not optimize away the chown() system call when the file's owner
          and group already have the desired value.  This optimization was
          incorrect, as it failed to updated the last-changed time and reset
          special permission bits, as POSIX requires.

          Do not report an error if the owner or group of a
          recursively-encountered symbolic link cannot be updated because
          the file system does not support it.

        * NEWS: Document the above.

        * src/chgrp.c (main): Check for incompatible options.  -R --dereference
        requires either -H or -L, and -R -h requires -P.  If -H, specify
        FTS_PHYSICAL as well as FTS_COMFOLLOW; this is faster.  Make this
        file as much like chown.c as possible.
        * src/chown.c (main): Likewise.

        * src/chown-core.c (change_file_owner): Use ent->fts_statp only if
        needed.  Chown a directory only after chowning its children; this
        avoids problems if the new directory ownership doesn't permit
        access to the children.  Dereference symlinks before doing
        ROOT_DEV_INO_CHECK, not after, so that we catch symlinks to /.
        Do not optimize away the chown() system call when the file's owner
        and group already have the desired value.  POSIX does not permit
        this optimization.  Rely on chown and lchown to do the right
        thing with symlinks and/or -1 arguments, now that we have wrappers
        to do this.  Use ENOTSUPP not ENOSYS, and ignore all ENOTSUPP
        errors, not just command-line errors.
        (chown_files): Pass FTS_NOSTAT to xfts_open if we don't need file status.

        * src/system.h (ENOTSUP): Remove.

        * tests/chgrp/basic: Use chown --from to discover whether the
        group changed, since chgrp now changes unconditionally.  This
        complicates the sed script a bit.  Do not specify --dereference,
        since it's the default (and we want to test this).  Adjust output
        to match the fact that chgrp no longer optimizes the case of
        changing a file's group to the same value as before.
        * tests/chgrp/posix-H: Do not attempt to combine -h and -H; these
        options are incompatible, and their behavior is undefined with POSIX.
        (changed, not_changed): Adjust to match the fact that -h is no longer
        specified.  Sort names.
        * tests/chown/deref: Adjust error-diagnostic spelling to match new
        behavior.

2004-06-07  Paul Eggert  <eggert@cs.ucla.edu>

        * src/uname.c (main): Fix typo introduced on 2003-05-10 that
        prevented a diagnostic of any operands.

2004-06-08  Jim Meyering  <jim@meyering.net>

        * src/shred.c (direct_mode): Turn it on/off with directio, too.

2004-06-07  Jim Meyering  <jim@meyering.net>

        Enable direct-mode I/O (bypassing the buffer cache), if possible.
        Prompted by a suggestion from Kalle Olavi Niemitalo
        in http://bugs.debian.org/207035.
        * src/shred.c (direct_mode): New function.
        (do_wipefd): Turn on direct-mode I/O.
        (dopass): If a file's first write fails with EINVAL,
        turn off direct-mode I/O and retry the write.

2004-06-05  Paul Eggert  <eggert@cs.ucla.edu>

        * src/tr.c (main): "tr -d a b" is now a fatal error even if
        POSIXLY_CORRECT is set.  The POSIX SYNOPSIS does not allow this
        option combination.

2004-06-04  Paul Eggert  <eggert@cs.ucla.edu>

        * src/shred.c (dopass): Don't subtract 1 from the offset after
        a write error.  Problem reported by Jon Peatfield in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-06/msg00020.html

2004-06-02  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug reported by Buciuman Adrian in
        <http://mail.gnu.org/archive/html/bug-coreutils/2003-08/msg00105.html>
        where 'dd' created a file that was too large.  The bug was that dd
        assumed that the input file offset does not advance after a failed
        read; but POSIX says that the input file offset is undefined after
        a failed read.

        * src/dd.c (MAX_BLOCKSIZE): New macro.
        (input_seekable, input_seek_errno, input_offset,
        input_offset_overflow): New vars.
        (scanargs): Reject block sizes greater than MAX_BLOCKSIZE.
        (advance_input_offset): New function.
        (skip_via_lseek): Set errno to zero when reporting our failure,
        so that we don't report based on garbage errno.
        (skip): If fdesc is standard input, advance the input offset.
        Do not quit if reading, and if noerror was specified;
        POSIX seems to require this.
        If read fails on output file, report the earlier lseek failure
        instead; this fixes a FIXME in dd_copy.
        (advance_input_after_read_error): New function.
        (dd_copy): Use it, instead of assuming that failed reads
        do not advance the file pointer.  Advance input offset
        after nonfailed reads.  Advance only a partial block if
        the previous read (before the failed read) succeeded, and
        do not generate an output block of zeros in this case.
        (main): Determine initial input offset, seekability of input,
        and error if it wasn't seekable.

2004-06-02  Jim Meyering  <jim@meyering.net>

        rm (without -f) could hang unnecessarily when attempting to
        remove a symlink to a file on an off-line NFS-mounted partition.
        Reported by David Howells in https://bugzilla.redhat.com/124699.
        * src/remove.c (write_protected_non_symlink): New function.
        Don't invoke euidaccess on symlinks.
        (prompt): Use write_protected_non_symlink rather than using
        euidaccess directly, being careful not to call lstat twice for a file.

        Fix a bug in how the --output-delimiter=D option works with
        abutting byte or character ranges.  Reported by David Krider in
        http://lists.gnu.org/archive/html/bug-coreutils/2004-05/msg00132.html
        * src/cut.c (print_kth): Remove special case for open-ended range.
        (set_fields): Record the range start index for an interval even
        when it abuts another interval on its low side.
        Also record the range start index of the longest right-open-interval.
        * tests/cut/Test.pm: Add tests of --output-delimiter=S with
        abutting and overlapping byte ranges.

2004-06-01  Paul Eggert  <eggert@cs.ucla.edu>

        Some POSIX-conformance cleanups for tr.

        * src/tr.c (posix_pedantic): Remove; no longer needed since
        we need to test this in just one place now.
        (usage): Mention -C.
        (unquote): Note that \055, \n, etc are escaped.
        Do not worry about POSIXLY_CORRECT when warning about ambiguous
        escape sequences.
        \ at end of string stands for itself.
        Do not diagnose invalid backslash escapes: POSIX says the behavior
        is unspecified in this case, so we don't need to diagnose it.
        (main): Add support for -C (currently an alias for -c).
        Do not diagnose 'tr [:upper:] [:upper:], as POSIX does not require
        a diagnostic here.
        * tests/tr/Test.pm: New tests bs-055, bs-at-end, repeat-Compl.
        Fix comment for range-a-a.

2004-05-25  Paul Eggert  <eggert@cs.ucla.edu>

        Improve the efficiency (and in one case, correctness) of code
        that reads symlinks.

        * src/copy.c (copy_internal): Don't use alloca, as it can mess up
        royally if the link length is long (e.g., GNU/Hurd).  Use
        xreadlink instead, it's safer.  Don't bother to read the link if
        it's the wrong size.  Add a FIXME because this area is a bit murky
        and undocumented.
        * src/ls.c (get_link_name): Update use of xreadlink.
        * src/readlink.c (main): Likewise.
        * src/stat.c (print_stat): Likewise.

2004-06-01  Jim Meyering  <jim@meyering.net>

        * src/env.c (main): Prefer the notation `STREQ (a, b)'
        over `!strcmp (a, b)'.
        * src/sort.c (main, sort_buffer_size): Prefer the notation
        `STREQ (a, b)' over `strcmp (a, b) == 0'.
        * src/date.c (batch_convert): Likewise.
        * src/expr.c (nextarg): Likewise.
        * src/su.c (correct_password, restricted_shell, main): Likewise.
        * src/ptx.c (swallow_file_in_memory, main): Likewise.
        * src/test.c (binary_operator, and, or, main): Likewise.

2004-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: echo compatibility cleanup.
        * doc/coreutils.texi (echo invocation): Document the changes.
        * src/echo.c (V9_ECHO): Remove; always enabled.
        (DEFAULT_ECHO_TO_XPG): Renamed from V9_DEFAULT, so that
        we use the same naming convention as bash.  Now an enum,
        not a macro.
        (usage): Reword to mention -e/-E more accurately.
        Mention \0NNN (the POSIX syntax) rather than \NNN (nonstandard).
        (hextobin): New function.
        (main): Use bool rather than int for local vars when appropriate.
        Do not allow options if POSIXLY_CORRECT, unless we are using
        BSD semantics and the first argument is "-n".
        Don't pass unnecessary extra arg to parse_long_options.
        do_v9 now defaults to DEFAULT_ECHO_TO_XPG, not to allow_options.
        Do not look for options if !allow_options.
        Use size_t rather than int when appropriate.
        Open-code option test rather than using strrchr.
        Use faster test for "-".
        Avoid redundant argc test.
        Add support for \x, for Bash compatibility.
        Use e.g. '\a' rather than '\007', for portability to EBCDIC hosts.
        When '\c' is encountered, stop printing immediately, as POSIX
        requires.
        Add support for \xhh syntax.
        Add support for \0ooo syntax; POSIX requires this.

2004-06-01  Jim Meyering  <jim@meyering.net>

        * Use automake-1.8b.  Regenerate dependent files.

2004-05-31  Jim Meyering  <jim@meyering.net>

        * tests/Makefile.am.in (TESTS_ENVIRONMENT): Define PATH to include
        the build src/ directory -- at the front.
        ($(srcdir)/$x-tests): Depend on Makefile.am.
        Use $x as the program name, except when it would be `test' (test is
        the sole program tested via mk-script that is also a shell built-in).
        In that case, use the old ../../src/$x.

2004-05-30  Jim Meyering  <jim@meyering.net>

        Work around HPUX /bin/cc compiler bug that is exposed, now that
        sets are arrays of type `bool'.  More details here:
        http://lists.gnu.org/archive/html/bug-gnulib/2004-05/msg00094.html
        FIXME: verify that the above URL points to the right message

        * src/tr.c (card_of_complement): Use cleaner `sizeof in_set'
        rather than `N_CHARS * sizeof(in_set[0])'.  Using HPUX's /bin/cc
        (aC++/ANSI C B3910B A.05.55 [Dec 04 2003]) on an ia64-hp-hpux11.22
        system, those two expressions are not the same (256 vs. 1024).
        The effect of this problem was that `tr -c x y' would fail:
        tr: when not truncating set1, string2 must be non-empty
        (set_initialize): Remove unnecessary initialization of the `in_set'
        buffer; that initialization triggered the same compiler bug as above.

2004-05-29  Paul Eggert  <eggert@cs.ucla.edu>

        tr cleanup, mostly having to do with integer type ranges.
        Remove all casts.

        * tests/tr/Test.pm: Add a few tests for the below.  Alas, most of
        the test cases wouldn't be portable, or would take too much CPU
        time, or both.

        * src/tr.c (N_CHARS, N_CHAR_CLASSES): Now an enum, not a macro.
        This is safe since the code already assumes N_CHARS fits in int.
        (Filter): Remove: we want to prototype everything.
        (ORD, CHR): Remove.  All uses removed.  Some replaced with:
        (uchar): New function.  All places where a char must be converted
        to an unsigned char are now done this way, not by ad-hoc methods.
        (count): New type.  Use it whenever counts or states are needed.
        (BEGIN_STATE): Increase from INT_MAX - 1 (which was bogus, anyway,
        since we used it in an unsigned int context) to UINTMAX_MAX - 1.
        (REPEAT_COUNT_MAXIMUM): New macro.  Use it in place of BEGIN_STATE
        whenever appropriate.
        (NOT_A_CHAR): Remove global macro; now a local enum.
        (UL_LOWER, UL_UPPER, UL_NONE): No longer specify values, since
        the rest of the code no longer depends on them.
        (class_ok): Remove; all uses changed to use inline comparisons.
        (RE_NO_TYPE): Remove; wasn't used or needed.
        (struct List_element): normal_char and equiv_code are now unsigned
        char, not int.
        first_char, last_char, and the_repeated_char are now unsigned char,
        not unsigned int.  repeat_count is now count, not size_t.
        All uses changed.
        (struct Spec_list): state is now count, not unsigned int.
        lengthis now count, not size_t.
        n_indefinite_repeats is now size_t, not int.
        has_equiv_class, has_char_class, and has_restricted_char_class
        are now bool, not int.  All uses changed.
        (struct E_string): s is now char *, not unsigned char *.
        escaped is now bool *, not int *.  All uses changed.
        (ES_MATCH): Remove macro, replacing with:
        (es_match): New inline function.  All uses changed.
        (squeeze_repeats, complement, posix_pedantic, truncate_set1,
        translating): Now bool, not int.
        (io_buf): Now char array, not unsigned char.
        (SET_TYPE): Remove.  All uses replaced with bool.
        (is_equiv_class_member, unquote, append_range, append_char_class,
        append_equiv_class, find_closing_delim, star_digits_closebracket,
        build_spec_list, parse_str, homogeneous_spec_list):
        Now returns bool, not int.  All uses changed.
        (is_equiv_class_member): Now inline.
        (is_equiv_class_member, is_char_class_member, make_printable_str,
        append_normal_char, append_range, append_repeated_char,
        get_s2_spec_stats):
        Args are now of proper integer type.
        (unquote, look_up_char_class, make_printable_str,
        append_equiv_class, build_spec_list, squeeze_filter):
        Avoid unsigned char *p; gently convert *p to unsigned char instead.
        (unquote, get_spec_stats): Do not jump past declarations and then
        use them; C doesn't allow this in portable programs.
        (make_printable_str): Check for overflow in size calculations.
        (xmemdup): Remove.  All uses rewritten.
        (find_bracketed_repeat): Args are now of proper pointer-to-integer
        type.  Do not reject [c*0].  Use xstrtoumax, not xstrtoul.
        (find_bracketed_repeat, star_digits_closebracket): Check that the
        digits are not escaped.
        (build_spec_list): Don't bother to copy opnd_str; not needed.
        (build_spec_list, get_next): Simplify internal logic a bit.
        (card_of_complement): Fix bug due to char overflow.
        (get_spec_stats): Don't assume len fits into int.
        Check for integer overflow.  Use abort() rather than assert(0).
        (string2_extend): Fix subscript error: is_char_class_member (..., 255)
        was being invoked.
        (squeeze_filter): READER is never null now; simplify code.
        READER arg now has a simpler type.  Remove unnecessary casts.
        (squeeze_filter, main): Calls to fwrite improperly checked result
        against zero, rather than against requested size.
        (plain_read): New function.
        (read_and_delete, read_and_xlate):
        Remove unused filter arg, and don't worry about hit_eof.
        Simplify by using plain_read.
        (set_initialize): Args are bool and bool *, not int and SET_TYPE *.
        (main): Always pass a non-null procedure to squeeze_filter.
        Rewrite so that class_ok isn't needed.

2004-05-29  Paul Eggert  <eggert@cs.ucla.edu>

        * src/shred.c (dosync): Ignore EBADF errors, as IRIX 6.5
        fdatasync reports EBADF when syncing (unwritable) directories.
        Problem reported by Albert Chin-A-Young in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-05/msg00165.html

2004-05-29  Jim Meyering  <jim@meyering.net>

        * tests/chown/deref: Fix typo: use ls -ldo, not ls -ldg.
        Patch from Albert Chin.

        * src/ptx.c (text_buffer_maxend): Remove declaration of unused variable.

        * src/remove.c (push_dir): Merge declaration and adjacent assignment
        into a single statement.

2004-05-28  Jim Meyering  <jim@meyering.net>

        * src/remove.c (AD_mark_helper): Eliminate an unnecessary comparison.

2004-05-22  Jim Meyering  <jim@meyering.net>

        rm -r would get a failed assertion when run from an inaccessible
        directory and with two or more command line arguments including an
        absolute-named directory followed by a relative-named directory.

        * src/remove.h (struct rm_options) [require_restore_cwd]: New member.
        * src/remove.c (struct cwd_state): Define.
        (AD_pop_and_chdir): Redesign interface so that a restore_cwd failure
        can be detected by the caller.  Instead of returning a malloc'd
        directory name, communicate it to caller via a new parameter, and
        return an indication of whether restore_cwd failed.  Update caller.
        Eliminate an unnecessary call to AC_stack_top.
        (remove_dir): Change type of cwd_state parameter to `struct cwd_state'
        so we can now communicate to caller whether/how functions like
        restore_cwd have failed.  Update caller.
        (rm_1): Fail if we've failed to restore the working directory
        and the name of the next file to remove is `.'-relative.
        (rm): Fail if the require_restore_cwd flag is true and we've
        failed to restore the working directory.
        * src/mv.c (rm_option_init): Initialize new member,
        x->require_restore_cwd.
        * src/rm.c (rm_option_init): Likewise.

2004-05-21  Jim Meyering  <jim@meyering.net>

        * tests/rm/inaccessible: New test for the above fix.
        * tests/rm/Makefile.am (TESTS): Add inaccessible.

        * src/remove.c (rm): Use free rather than XFREE.
        (remove_dir): Use xmalloc, not XMALLOC.
        (ds_init): Likewise.

2004-05-20  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (sc_unmarked_diagnostics): Now that the unmarked
        diagnostics in shred.c have been fixed, don't exempt shred.c from
        this check.

        * src/shred.c: Use translatable diagnostics, e.g.
        change "%s: remove" to _("%s: failed to remove") and
        change "%s: close"  to _("%s: failed to close").

        * src/shred.c (names): Bring back lower-case letters, "_", and
        ".".  But continue to omit +, =, %, @, #, as they're either
        shell metacharacters (for some shells) or are not in some
        character sets, or (in the case of '%') must be a
        metacharacter somewhere.

2004-05-16  Paul Eggert  <eggert@cs.ucla.edu>

        * src/cut.c (cut_fields): Adjust to new signature of getndelim2.

2004-05-17  Jim Meyering  <jim@meyering.net>

        * src/shred.c (incname): Decrement `len' only once per loop iteration.

        chgrp and chown now dereference symlinks by default, per POSIX.
        Reported by Michal Politowski as http://bugs.debian.org/249177.

        * src/chown-core.c (chopt_init): Affect each symlink referent by default.
        * src/chown.c (usage): Update to reflect this.
        * src/chgrp.c (usage): Likewise.
        * NEWS: Describe the change.
        Adapt tests accordingly.
        * tests/chgrp/basic: Use -h where necessary to retain semantics.
        * tests/chgrp/deref: Likewise.
        * tests/chgrp/posix-H: Likewise.

2004-05-15  Paul Eggert  <eggert@cs.ucla.edu>

        In shred, check for errors from fdatasync more carefully.  If
        fdatasync fails with errno==EINVAL, it means this implementation
        does not support synchronized I/O for this file.  Do not report
        this as an error, as (for example) AIX 5.2 fdatasync reports it
        for raw disk devices.  Problem reported by Albert Chin in
        <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00028.html>.

        Check for write errors, though: the old code ignored them.
        Improve error checking in a few other cases, too (e.g., close of a
        directory).

        Also, change several 'int' values to 'bool', so that the error
        checking is a bit clearer.  Similarly, change unsigned values
        to size_t where appropriate.

        * src/shred.c: Include "dirname.h".
        (datasync) [!HAVE_FDATASYNC]: Remove.
        (dosync): New function.
        (dopass): Use it.  Return 1 on write error, -1 on other error.
        All callers changed.  Report write error if dosync does.
        (do_wipefd, wipefd, wipename, wipefile): Return bool (true/false),
        not int (0/-1).  All callers changed.  Return false if there's a
        write error.
        (incname): Return bool (true/false), not int (0/1).  Accept
        size_t length, not unsigned.  All callers changed.  Do not
        bother checking for non-digits; it can't happen.  Replace
        recursion with iteration.
        (wipename): Use dir_name, base_name, etc. instead of assuming
        Unix file names.  Use size_t for length, not unsigned.
        Report error if unlink or close fails.
        (wipename, main): Use bool for booleans.

        (names): Use only digits and uppercase letters, for greater
        portability.

2004-05-16  Jim Meyering  <jim@meyering.net>

        * tests/chown/deref: New test for the yesterday's change.
        * tests/chown/Makefile.am (TESTS): Add deref.

2004-05-15  Jim Meyering  <jim@meyering.net>

        chown --dereference did nothing when the owner/group of a
        symlink matched the desired owner/group.  Reported by David Malone.
        Also reported in 1999 as http://bugs.debian.org/39642.

        * src/chown-core.c (change_file_owner): When --dereference has
        been specified, and when processing a symlink, stat it to get the
        owner and group of the referent.

2004-05-14  Jim Meyering  <jim@meyering.net>

        * man/pwd.x, man/echo.x, man/printf.x: Fix typo:
        s/supercede/supersede/ reported by Andrew Fabbro.

2004-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        Improve performance of `sort -m' on large files, at the cost of
        making some contrived examples unsafe.  POSIX allows this
        optimization.  Performance problem reported by Jonathan Baker in
        <http://mail.gnu.org/archive/html/bug-coreutils/2004-05/msg00071.html>.

        * src/sort.c (first_same_file): Do not treat input pipes
        differently from other files.
        * doc/coreutils.texi (sort invocation): Document that "sort -m -o F"
        might write F before reading all the input.
        * NEWS: Likewise.

2004-05-12  Paul Eggert  <eggert@cs.ucla.edu>

        * src/od.c (print_ascii, dump_strings): Use e.g. '\a' rather than
        '\007', for portability to EBCDIC hosts.
        * src/printf.c (print_esc_char): Likewise.
        * src/tr.c (unquote, make_printable_str): Likewise.

2004-05-12  Jim Meyering  <jim@meyering.net>

        * src/remove.c (AD_pop_and_chdir): Move lstat-`.' into if-block
        where the result is used.  This avoids one unnecessary lstat call
        per command line argument.

2004-05-12  Paul Eggert  <eggert@cs.ucla.edu>

        Don't assume that "make -C" works; Solaris "make" doesn't have -C.

        * src/Makefile.am (all_programs.list): New rule, copied from
        man/Makefile.am and tests/Makefile.am, except that we use the
        system tr rather than ./tr and we don't use tr -s.
        * tests/Makefile.am (all_programs): Use it.
        * man/Makefile.am (all_programs): Likewise.  Renamed from programs,
        for consistency.  All uses changed.

2004-05-11  Jim Meyering  <jim@meyering.net>

        * tests/rm/unread3: New test, for the above fix and today's
        lib/save-cwd.c improvement.
        * tests/rm/Makefile.am (TESTS): Add unread3.

        * src/rm.c: Don't include "save-cwd.h".  It's no longer used.

2004-05-10  Jim Meyering  <jim@meyering.net>

        * tests/install/trap: New file.  Test for bug fix of 2004-04-18.
        * tests/install/Makefile.am (TESTS): Add trap.

        * src/remove.c (AD_push): Don't use errno in diagnostic about
        `changed dev/ino'.

        Remove these generated files from CVS.
        * tests/cut/cut-tests, tests/date/date-tests, tests/join/join-tests:
        * tests/ls/ls-tests, tests/pr/pr-tests, tests/tac/tac-tests:
        * tests/tail/tail-tests, tests/test/test-tests, tests/tr/range-tests:
        * tests/tr/tr-tests, tests/wc/wc-tests:

2004-05-09  Jim Meyering  <jim@meyering.net>

        * src/tr.c (unquote): Use xcalloc rather than xmalloc and
        a loop initializing the just-allocated memory to zero.

2004-05-08  Jim Meyering  <jim@meyering.net>

        * tests/rm/no-give-up: New file; check for today's fix.
        * tests/rm/Makefile.am (TESTS): Add no-give-up.

2004-05-08  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug where "rm" gave up too easily, reported by Dan Jacobsen in
        <http://mail.gnu.org/archive/html/bug-coreutils/2004-05/msg00013.html>.

        * src/remove.c (remove_entry): Check for errno values like ENOENT
        that show the file cannot be directory, instead of for errno
        values like EPERM that show the file might be a directory.  This
        is necessary because, when a single unlink() call has multiple
        reasons to fail, it can set errno to any of those reasons; it's
        only the rare errno value like ENOENT that excludes all the other
        possible reasons to fail even when the file is a directory.
        (remove_cwd_entries): Don't attempt chdir if the file is known
        to not be a directory.
        (remove_dir): Use the same method that remove_cwd_entries uses
        (for some reason they differed).  Don't assert that saved_errno
        must be EPERM; it might be just about anything.

2004-05-06  Jim Meyering  <jim@meyering.net>

        * src/id.c (xgetgroups): Use xnmalloc, rather than xmalloc.
        Don't add `1' to the buffer size (it was to protect against malloc
        implementations that fail to allocate a buffer of size zero).
        That is no longer necessary, since we use a malloc wrapper
        on such systems.

        * src/wc.c (get_input_fstatus): Use xnmalloc, rather than xmalloc.
        * src/head.c (elide_tail_bytes_pipe): Likewise.
        * src/df.c (main): Likewise.
        * src/shred.c (do_wipefd): Likewise.
        * src/users.c (list_entries_users): Likewise.
        * src/tail.c (main): Likewise.
        * src/md5sum.c (main): Likewise.

2004-04-29  Paul Eggert  <eggert@cs.ucla.edu>

        * src/df.c (show_disk, show_point): If several filesystems are
        mounted on the same mount point, prefer the last one, not the first.
        Problem reported by Christian Jones in
        <http://mail.gnu.org/archive/html/bug-coreutils/2004-04/msg00200.html>.
        (show_disk): Remove unused statp arg.  Return bool, not int.
        (show_point): Rewrite to avoid gotos.  Use the same algorithm
        for lofs and dummies for each pass through the mount table,
        rather than subtly different algorithms (which are probably
        inadvertent).

2004-05-03  Jim Meyering  <jim@meyering.net>

        * Makefile.am (EXTRA_DIST): Add m4/ChangeLog, now that we no longer
        have m4/Makefile*.

2004-05-01  Jim Meyering  <jim@meyering.net>

        When chown or chgrp is modifying the referent of a symlink,
        use the chown(2) function, if possible.
        * src/chown-core.c (change_file_owner): Don't hard-code the
        open/fchown/close kludge here.  Use `chown' instead.
        The chown function works just fine on conforming systems.
        Other systems now go through the new chown wrapper that
        resorts to the old kludge.

        * src/chown-core.c (change_file_owner): Add a comment.

2004-04-27  Jim Meyering  <jim@meyering.net>

        * src/ptx.c: Make over 40 global extern variables `static'.
        (syntax_table, re_syntax_table): Remove declarations of two unused
        variables (they were exposed by the above change).

        * src/du.c (G_fail, opt_nul_terminate_output): Declare `static'.
        * src/ln.c (backup_type): Likewise.

        * src/remove.c (rm): Add `extern' keyword.
        * src/cp-hash.c (forget_created, remember_created)
        (src_to_dest_lookup, remember_copied, hash_init, forget_all): Likewise.
        * src/copy.c (dest_info_init, src_info_init, copy): Likewise.
        * src/chown-core.c (chopt_init, chopt_free, gid_to_name)
        (uid_to_name, chown_files): Likewise.

        * src/Makefile.am (sc_tight_scope): New rule.
        * Makefile.maint (sc_tight_scope): New rule.
        (syntax-check-rules): Add it.

2004-04-26  Jim Meyering  <jim@meyering.net>

        * Use automake-1.8.4.  Regenerate dependent files.

        * src/sort.c (limfield): Make a comment clearer.

2004-04-25  Paul Eggert  <eggert@twinsun.com>

        Fix POSIX-conformance bug: "sort -k 3,3.5b" is supposed to skip
        leading blanks when computing the location of the field end;
        it is not supposed to skip trailing blanks.  Solaris 8 "sort"
        does conform to POSIX.  Also fix the documentation to clarify
        this and related issues.

        * doc/coreutils.texi (sort invocation): Mention -k earlier, so
        that the options are in alphabetical order.  Describe how -b works
        more-accurately; this involves fixing some examples, too.  Mention
        what happens if the start field falls after an end field or after
        a line end.  Warn about using -k without -b, -g, -M, -n, or -t.
        Add an example of how to sort IPv4 addresses and Apache Common
        Log Format dates.  Remove a duplicate example.
        (Putting the tools together): Use separate options rather
        than agglomerating them.
        * src/sort.c (limfield): Use skipeblanks, not skipsblanks, to
        decode whether to skip leading blanks.
        (trailing_blanks): Remove.
        (fillbuf, getmonth, keycompare): Don't trim trailing blanks.

        * tests/pr/Test.pm: Fix typo in env_default comment.
        * tests/sort/Test.pm: Likewise.
        (18c, 18d): Reverse the order of output lines, so that the
        test cases conform to POSIX.

2004-04-22  Paul Eggert  <eggert@twinsun.com>

        More signal-handling cleanup for ls.c.  Do not allow signals to
        happen between arbitrary output bytes, as the
        restore-default-color sequence can bollix up multibyte chars or
        color-change sequences in the ordinary output.  Instead, process
        signals only between printing a file name and changing the color
        back to non_filename_text color.  That way, if the signal handler
        changes the color (to the default), 'ls' will change it back when
        'ls' continues (after being suspended).

        Also, do not bother with signal-handling unless stdout is a
        controlling terminal; this lets stdio buffer better when "ls
        --color" is piped or sent to a file.

        * src/ls.c (sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]: New macros.
        Do not include "full-write.h"; no longer needed.
        (tcgetpgrp) [! HAVE_TCGETPGRP]: New macro.
        (put_indicator_direct): Remove.  All callers changed to use
        put_indicator.
        (caught_signals, interrupt_signal, stop_signal_count): New vars.
        (restore_default_color): Don't bother checking for put_indicator
        failure.
        (sighandler): Don't handle SIGTSTP; that's another handler now.
        Simply set interrupt_signal to the signal, then exit.
        (stophandler, process_signals): New functions.
        (main): Don't output any color changes until _after_ the signal
        handlers are set up.  This fixes a race condition where 'ls'
        could be interrupted while initializing colors, and leaving the
        terminal in an undesirable state.
        Don't mess with signal-handling if standard output is not a
        controlling terminal.
        When exiting, restore the default color, then restore the
        default signal handling, then act on any signals that weren't
        acted on yet.
        Do not print //DIRED// etc. in colors; this avoids the need
        to catch signals when printing them.
        (print_name_with_quoting): Process signals just before switching
        color back to non_filename_text.

2004-04-23  Jim Meyering  <jim@meyering.net>

        Avoid segfault on systems for which SIZE_MAX != (size_t) -1.
        * src/ls.c (quote_name): Use SIZE_MAX, not -1, in calls
        of quotearg_buffer.  Patch by Mikulas Patocka.

2004-04-18  Paul Eggert  <eggert@twinsun.com>

        tee ignored SIGPIPE, but POSIX doesn't allow this.

        * src/tee.c (main): Do not ignore SIGPIPE, as POSIX 1003.1-2001
        does not allow this.  This undoes the 1996-10-24 patch.

2004-04-18  Paul Eggert  <eggert@twinsun.com>

        Signal-handling cleanup for coreutils.  Here are the highlights:

         - csplit sometimes failed to remove files when interrupted.
         - csplit didn't clean up if two signals arrived nearly simultaneously.
         - install -s would infloop on System V if SIGCHLD was ignored.
         - ls could incorrectly restore color if multiple signals
           arrived nearly simultaneously.

        * src/csplit.c (sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
        Define.
        (filename_space, prefix, suffix, digits, files_created, remove_files):
        Now volatile.
        (caught_signals): New var.
        (cleanup): Block signals while deleting all files.
        (cleanup_fatal, handle_line_error, regexp_error):
        Mark with ATTRIBUTE_NORETURN.
        (create_output_file, close_output_file, interrupt_handler):
        Block signals while changing the number of output files,
        to fix some race conditions.
        (delete_all_files): Do nothing if remove_files is zero.
        Clear files_created.
        (main): Don't mess with signals until after argument processing
        is done.

        * src/csplit.c (main): Rewrite signal-catching code to make it
        similar to other coreutils programs.  When processing signals,
        block all signals that we catch, but do not block signals that we
        don't catch.  Avoid problems with unsigned int warnings.
        * src/ls.c (main): Likewise.
        * src/sort.c (main): Likewise.

        * src/csplit.c (interrupt_handler):
        Use void, not (obsolete) RETSIGTYPE.
        * src/shred.c (sigill_handler, isaac_seed_machdep): Likewise.

        * src/csplit.c (interrupt_handler) [defined SA_NOCLDSTOP]:
        Use simpler "signal (sig, SIG_DFL)" rather than sigaction equivalent.
        * src/ls.c (sighandler) [defined SA_NOCLDSTOP]: Likewise.
        * src/sort.c (sighandler) [defined SA_NOCLDSTOP]: Likewise.
        * src/nohup.c (main) [!defined _POSIX_SOURCE]: Likewise, except
        for SIG_IGN.
        * src/tee.c (main) [!defined _POSIX_SOURCE]: Likewise.

        * src/install.c: Include <signal.h>.
        (main) [defined SIGCHLD]: Set SIGCHLD handler to the default, if -s is
        given, since System V fork+wait does not work if SIGCHLD is ignored.

        * src/ls.c (sighandler) [!defined SA_NOCLDSTOP]: Reset signal
        handler to self, not to SIG_IGN, since SIGTSTP can be received
        more than once.
        (main): Use SA_RESTART, as that is simpler than checking for EINTR
        failures all over the place.

2004-04-20  Jim Meyering  <jim@meyering.net>

        * src/remove.c (is_empty_dir): Clarify comment.

        * man/help2man: Accept new option: --program-name=NAME, so that we
        can override the one in --version output.  This is needed solely
        so that test.1 doesn't refer to `[' as the program name.
        Reported by Benjamin Cutler as http://bugs.debian.org/205251.
        * man/Makefile.am (.x.1): Use help2man's new --program-name option.

        * src/pwd.c: Don't include pathmax.h; system.h already does it.

        * src/cut.c (cut_fields): Free buffer upon getndelim2 failure.

2004-04-19  Jim Meyering  <jim@meyering.net>

        * src/shred.c (isaac_seed_start) [AVOID_USED_UNINITIALIZED_WARNINGS]:
        Initialize a buffer to avoid warnings from tools like valgrind.

        * Makefile.maint (sc_trailing_blank): New rule.
        (syntax-check-rules): Add it.
        * .x-sc_trailing_blank: New file.

        Make pwd work even if the resulting name is so long that getcwd fails.
        * src/pwd.c: (path_free, path_init, path_prepend): New functions.
        (nth_parent, find_dir_entry, robust_getcwd): New functions.
        (main): First try getcwd, then, upon failure, robust_getcwd.

2004-04-18  Jim Meyering  <jim@meyering.net>

        * src/who.c (print_user): Use xrealloc here, rather than
        unchecked realloc.  Remove anachronistic casts.

        * src/remove.c (full_filename_): Don't leak upon failed realloc.

        * src/system.h (readdir_ignoring_dot_and_dotdot): New inline function,
        from remove.c.
        * src/remove.c (readdir_ignoring_dotdirs): Move function to system.h,
        renaming it.  Update uses.

2004-04-17  Jim Meyering  <jim@meyering.net>

        * configure.ac: Depend on automake-1.8.3.

        * src/join.c (add_file_name): Declare function to be `static'.

        * src/remove.c (ds_init, ds_free): Likewise.

        * Makefile.maint (sc_prohibit_jm_in_m4): New rule.

2004-04-13  Paul Eggert  <eggert@twinsun.com>

        Use page-aligned buffers whenever we bother to do I/O using buffer

2004-04-14  Jim Meyering  <jim@meyering.net>

        Remove m4/Makefile.am: it's no longer needed, with newer automake
        * configure.ac (AC_CONFIG_FILES): Remove m4/Makefile.in from the list.
        * Makefile.am (SUBDIRS): Remove `m4' from the list.

2004-04-13  Jim Meyering  <jim@meyering.net>

        * configure.ac: Change `jm_' in AC_DEFINE'd names to `gl_'.

2004-03-27  Paul Eggert  <eggert@twinsun.com>

        * NEWS: cp -pu and mv -u (when copying) now take the destination
        file system time stamp resolution into account.
        * doc/coreutils.texi (mv invocation): Document this.
        (cp invocation): Document -u (it was missing!) with new behavior.

        * src/copy.c: Include "utimecmp.h".
        (copy_internal): Compare time stamps using utimecmp rather than
        MTIME_CMP.

2004-04-09  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (.re-list): New rule/file, to replace
        hard-coded list of header file names.
        (sc_system_h_headers): Use the new file.
        Don't look for sys2.h anymore.

        * src/system.h: Include new "stat-macros.h" rather than hard-coding
        all of its macro definitions -- the list was slightly out of date.
        Suggestion from Dmitry V. Levin.

2004-04-08  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: Remove noctty flag from dd.  Suggested by Philippe Troin.
        * doc/coreutils.texi (dd invocation): Likewise.
        * src/shred.c (O_NOCTTY): Remove redundant decl.
        * src/dd.c (flags, usage): Remove noctty flag.
        (main): Always use O_NOCTTY when opening files.

2004-04-08  Jim Meyering  <jim@meyering.net>

        * src/dd.c (dd_copy): Mark two diagnostics for translations.
        (set_fd_flags): Undo part of today's change: it's a little
        cleaner -- and more efficient in the common case -- to go
        ahead and OR in the -1 when fcntl fails.

        * Makefile.maint (sc_dd_max_sym_length): New target.
        (syntax-check-rules): Add it.

        * src/md5sum.c (PROGRAM_NAME) [algorithm == ALG_SHA1]:
        Correct spelling: s/shasum/sha1sum.  Reported by Jesse Kornblum.

        * src/dd.c (set_fd_flags): Don't OR in -1 when fcntl fails.
        Rename parameter, flags, to avoid shadowing global.
        (LONGEST_SYMBOL): Tweak comment.

2004-04-07  Paul Eggert  <eggert@twinsun.com>

        * NEWS: New dd conv= symbols nocreat, excl, fdatasync, fsync,
        and new dd options iflag= and oflag=.
        * src/dd.c (usage): Likewise.
        * src/Makefile.am (dd_LDADD, shred_LDADD): Add fdatasync's lib.
        * src/dd.c (fdatasync) [!HAVE_FDATASYNC]: New macro.
        (C_NOCREAT, C_EXCL, C_FDATASYNC, C_FSYNC): New macros.
        (input_flags, output_flags): New vars.
        (LONGEST_SYMBOL): New macro.
        (struct symbol_value): Renamed from struct conversion.  Members
        symbol and value renamed from convname and conversion.  The
        symbol value is now an array instead of a pointer; this saves
        a bit of space and time in practice.  All uses changed.
        (conversions): Add nocreat, excl, fdatasync, fsync.  Now const.
        (flags): New constant array.
        (iflag_error_msgid, oflag_error_msgid): New constants.
        (parse_symbols): Renamed from parse_conversion and generalized
        to handle either conversion or flag symbols.
        (scanargs): Adjust uses of parse_symbols accodingly.  Add
        support for iflag= and oflag=.  Reject attempts to use
        both excl and nocreat.
        (set_fd_flags): New function.
        (dd_copy): Just return X rather than calling quit (X), since our
        caller invokes quit with the returned value.  Add support for
        fdatasync and fsync.
        (main): Add support for iflag=, oflag=, and new conv= symbols.
        * src/system.h (O_DIRECT, O_DSYNC, O_NDELAY, O_NOFOLLOW,
        O_RSYNC, O_SYNC): Define to 0 if not already defined.

        * NEWS: Remove duplicate mention of BLOCKSIZE.

2004-04-02  Andreas Schwab  <schwab@suse.de>

        * src/stty.c: Add support for IUTF8 input flag.

2004-04-06  Jim Meyering  <jim@meyering.net>

        * src/system.h (makedev) [mkdev && !makedev]: Define in terms of mkdev.
        Interix spells it `mkdev'.  Reported by Mark Funkenhauser.

2004-04-04  Jim Meyering  <jim@meyering.net>

        A specified format is no longer automatically newline terminated.
        If you want a newline at the end of your format, use `\n'.
        * src/stat.c (print_it): Don't print a newline at the end of
        every format.
        (do_statfs): Add a newline at end of each default format string.

        for set_cloexec_flag.

2004-03-31  Jim Meyering  <jim@meyering.net>

        * tests/Fetish.pm (run_tests): Remove `.orig' file.
        Remove debugging diagnostic.

        Specifying an invalid --width=N (-w) or --gap-size=N (-g)
        would not elicit an error.
        * src/ptx.c: Include "xstrtol.h" and "quotearg.h".
        (main): Don't use atoi.  Use xstrtoul instead.

2004-03-30  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (sc_prohibit_atoi_atof): New rule.
        (syntax-check-rules): Add it.
        * .x-sc_prohibit_atoi_atof: New file.

2004-03-29  Jim Meyering  <jim@meyering.net>

        * tests/du/files0-from: Use new OUT_SUBST directive, so that this
        test is not sensitive to system-dependent block size differences.
        Prompted by a report of Solaris 8 differences from Paul Eggert.

        * tests/Fetish.pm: Accept new directives: OUT_SUBST, ERR_SUBST.
        Rename `%tmp' to `%actual'.  Reverse order of last two args to
        _compare_files (to $actual, $expected) so as to match declaration.

2004-03-28  Paul Eggert  <eggert@twinsun.com>

        Fix some gotchas encountered when porting to Solaris 8, using
        the Forte 6u2 compiler.

        * src/hostname.c [HAVE_SETHOSTNAME && !defined sethostname]:
        Declare sethostname, since no Solaris header does it.
        * src/who.c: Include "vasprintf.h", for asprintf.

2004-03-28  Jim Meyering  <jim@meyering.net>

        Minor optimization:
        * src/du.c (process_file): Don't record dev/inode for directories.

        Under some circumstances, without -c, du would mistakenly count the
        space of hard-linked files, not just the first one it encountered.
        Reported by Anthony Thyssen.
        * src/du.c (du_files): Don't ever clear the set of `seen' dev/inodes.

        * src/du.c: Rename global `print_totals' to `print_grand_total'.

        * src/du.c (main): Rearrange filtering loop to be a tiny bit
        more efficient.

        * src/chown-core.c: Don't include savedir.h -- no longer needed.
        * src/chmod.c: Likewise.

2004-03-25  Jim Meyering  <jim@meyering.net>

        * src/du.c (main): Remove now-unused declaration of `i'.

2004-03-24  Paul Eggert  <eggert@twinsun.com>

        * src/du.c (main): Filter out file names of length zero before
        invoking fts, so that they don't cause fatal errors.

2004-03-25  Jim Meyering  <jim@meyering.net>

        * tests/du/files0-from (zero-len): Add a test for the above.

2004-02-25  Paul Eggert  <eggert@twinsun.com>

        * NEWS: New environment var BLOCKSIZE.
        * lib/human.c (humblock): Support BLOCKSIZE as well as BLOCK_SIZE.
        * tests/envvar-check: Test for it.  Factor the code to simplify it.

2004-03-23  Paul Eggert  <eggert@twinsun.com>

        * NEWS: Shorten the du --files0-from announcement, and say
        "NUL-terminated" rather than "NUL-separated".
        * src/du.c (EXPECTED_BYTES_PER_FILE_NAME, DEFAULT_PROJECTED_N_FILES):
        Remove: not used.
        (usage): Say "NUL-terminated", not "NUL-separated".
        (main): Check for I/O error when istream is closed.
        Allow --files0-from=F even if F is empty; this specifies no files.
        (du_files): Now that we allow the list of files to be empty,
        handle that case.
        * tests/du/files0-from: Adjust to above changes to src/du.c.

2004-03-24  Jim Meyering  <jim@meyering.net>

        * tests/tail-2/assert: Avoid race condition that could cause
        spurious failure.  Based on a patch from Andreas Schwab.

2004-03-23  Jim Meyering  <jim@meyering.net>

        * src/du.c (main): Free the hash table, too.

2004-03-22  Jim Meyering  <jim@meyering.net>

        * man/Makefile.am (.x.1): Remove --info-page= option, reverting
        the change of 2004-01-22.  I can no longer reproduce the problem
        that prompted that change, and `info coreutils pr' would display the
        `printing text' section of the manual, not the one on `pr invocation'.

        * tests/du/files0-from (nul-1, nul-2): Adjust expected diagnostics
        to match corrected output.

        * src/du.c: Include "readtokens0.h" rather than "readtokens.h".
        (main): Use readtoken0 functions rather than readtokens.
        Don't use errno when diagnosing readtokens0 failure.
        Fix off-by-one error in the token number reported in a diagnostic.
        (du_files): Return bool, rather than int.
        (main): Call readtokens0_free.

2004-03-21  Jim Meyering  <jim@meyering.net>

        * src/remove.c (ds_free): Plug a small leak.

        * tests/Fetish.pm: Fix typo in comment.

2004-03-07  Jim Meyering  <jim@meyering.net>

        * NEWS: du accepts a new option --files0-from=FILE, where FILE
        contains a list of NUL-separated file names.

        * src/du.c: Include "readtokens.h".
        (usage): Describe the new option, and adjust the `Usage':
        with this option, no FILE may be specified on the command line.
        (main): Handle the new option.

        * tests/du/files0-from: New tests, for the above.
        * tests/du/Makefile.am (TESTS): Add files0-from.

        * src/factor.c (do_stdin): Reflect changes in use of readtoken.

2004-02-29  Paul Eggert  <eggert@twinsun.com>

        * NEWS: Add support for a new notation @N to get_date to represent
        the time stamp with numeric value N.  Improve support for
        fractional time stamps.  date's -d and -f options now accept them.
        Likewise for touch -t.  date has a new option --iso-8601=ns.

        * doc/coreutils.texi (touch invocation):
        Describe use of fractional seconds.
        (date invocation, Options for date): Likewise.
        * doc/getdate.texi (General date syntax, Time of day items): Likewise.
        * doc/coreutils.texi (date invocation): Mention effect of LC_TIME.
        (Options for date): Describe new --iso-8601=ns option.

        * doc/getdate.texi: Add copyright notice.  Change getdate to
        get_date when talking about the function name.
        (Seconds since the Epoch): New section, containing the time_t
        info moved from Date input formats section, along with new
        info about the @ syntax.  Mention negative time stamps,
        fractional time stamps, and leap seconds.
        (General date syntax): Modernize examples a bit to reflect new
        features.
        (General date syntax, Relative items in date strings):
        Use ' rather than " to quote formats.
        (Time of day items): Add an example with fractional seconds.
        Describe fractional-second syntax.

        * src/Makefile.am (touch_LDADD): New macro, since `touch' now
        needs clock_gettime.

        * src/date.c (enum Time_spec): New enum TIME_SPEC_NS.
        (time_spec_string, time_spec, show_date): Support it.
        (usage): Remove description of -ITIMESPEC, as it's obsolete and
        confusing.  Mention --iso-8601=ns.
        (batch_convert): getline returns ssize_t, not int.

        * src/touch.c (newtime): Now an array of two timespecs, one
        for access and one for modification.
        (ref_stats): Remove.
        (get_reldate): Use get_date's parameter profile.
        (touch, main): Adjust to above changes.
        (main): Work even if tm_year == INT_MAX (so long as long int is wider).
        Use gettime instead of gettimeofday, for new get_date signature.

        * tests/date/Test.pm (test_vector): New tests epoch, ns-10, ns-max32,
        ns-relative.

2004-03-15  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (alpha beta major): `Make' the emit_upload_commands
        target before updating $(prev_version_file).

        * tests/misc/date-sec: New file, to test for just-fixed bug in date.
        See today's change in lib/getdate.y.
        * tests/misc/Makefile.am (TESTS): Add date-sec.

2004-03-14  Jim Meyering  <jim@meyering.net>

        * announce-gen (print_changelog_deltas): Use `.sig' suffix for
        signature files, not `.asc'.  Reported by angico@yahoo.com.

2004-03-13  Jim Meyering  <jim@meyering.net>

        * src/cp.c (do_copy): Tweak wording in a diagnostic.
        Suggestion from Karl Berry.
        Include "quoatearg.h".
        (do_copy): Use quotearg_colon (not quote) for diagnostics
        that begin with `"%s:'.

        * src/nl.c (usage): Specify that nl uses _basic_ regular expressions.
        Suggestion from Dan Jacobson.

2004-03-12  Jim Meyering  <jim@meyering.net>

        * Version 5.2.1.

        Sometimes, when source and destination partition are different,
        mv mistakenly fails to preserve a hard link.  Reported by IIDA Yosiaki.

        * src/copy.c: When moving a set of N hard-linked files between
        partitions, via two or more command line arguments where the
        command line argument containing the Nth link contains no other
        link to that same file, mv would mistakenly copy the file, rather
        than hard-linking it to the other(s).  That happens because when the
        final link is processed, its link count has been reduced to 1 since
        the other links have been `copied' to the destination partition
        and the source links have been removed.
        (copy_internal): When in move mode, use the source dev/inode
        pair to look up destination name even when st_nlink == 1.
        * src/cp-hash.c (src_to_dest_lookup): New function.
        * src/cp-hash.h (src_to_dest_lookup): Add prototype.

        * announce-gen: Sync with autoconf.

        * tests/ls/time-1: Exit 77 (not 1) if we can't set up for the test.
        This was triggered on a Linux-2.2.19 system using a file system
        NFS-mounted from some sort of Sun.

2004-03-11  Jim Meyering  <jim@meyering.net>

        * Use automake-1.8.3.  Regenerate dependent files.

2004-03-10  Jim Meyering  <jim@meyering.net>

        * tests/du/deref-args: Also convert sizes in the 70-79 kB range,
        so that this test works with SELinux-enabled systems.
        Based on a patch from Tim Waugh.

        `join -1 x' would give a misleading diagnostic
        * src/join.c (string_to_join_field): Report that a non-numeric field
        number is invalid, rather than `so large that it is not representable'.
        * tests/join/Test.pm (invalid-j): New partial test for the above fix.

2004-03-06  Jim Meyering  <jim@meyering.net>

        cp --sparse=always sparse-image-file.img /dev/hda1 could
        produce an invalid copy on the destination device.

        * src/copy.c (copy_reg): Even with --sparse=always, try to
        make `holes' only if the destination is a regular file.
        Reported by Szakacsits Szabolcs.

2004-03-03  Paul Eggert  <eggert@twinsun.com>

        * src/nohup.c (main): Don't invoke set_cloexec_flag with
        a file descriptor of -1.

2004-03-02  Dmitry V. Levin  <ldv@altlinux.org>

        * src/nohup.c: Include "cloexec.h".
        (main): Set the copy of stderr to close on exec.

2004-03-01  Paul Eggert  <eggert@twinsun.com>

        * configure.ac: Include <signal.h> when checking for strsignal,
        sys_siglist, and friends.  Problem reported by Tony Leneis in
        <http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00136.html>.

2004-02-25  Paul Eggert  <eggert@twinsun.com>

        * tests/du/deref-args, tests/du/exclude, tests/du/slash:
        * tests/du/trailing-slash: Run envvar-check in case BLOCK_SIZE
        etc. are set.

2004-02-23  Paul Eggert  <eggert@twinsun.com>

2004-02-22  Jim Meyering  <jim@meyering.net>

        * src/du.c (usage): Separate -H and --si.  Say that the meaning
        of -H will soon change to that of --dereference-args (-D).

2004-02-21  Jim Meyering  <jim@meyering.net>

        * src/comm.c (usage): Tell what comm does when there are no options.
        Reword in terms of FILE1 and FILE2 rather than `left file' and
        `right file'.  Suggestion from Dan Jacobson.

2004-02-15  Paul Eggert  <eggert@twinsun.com>

        Fix some POSIX-conformance bugs in expr.

        * NEWS: document the following changes to src/expr.c.
        * doc/coreutils.texi (expr invocation): Likewise.
        Document what forms integers may take, and say "integer"
        consistently instead of "number".  Warn about operands
        that "expr" can misinterpret, and how to work around the
        problem.
        * src/expr.c (eval, eval7, eval6, eval5, eval4, eval3, eval2, eval1):
        Accept a bool argument specifying whether to evaluate the
        expression.  This is to allow short-circuit evaluation.  All
        callers changed.
        (null): Report that a string is zero even if it has
        a form like "-0" or "00".
        (eval1, eval): Use short-circuit evaluation for | and &.
        (eval): Return 0 if both arguments are null or zero, instead
        of returning the first argument.
        * tests/expr/basic: Add some tests for the above.

2004-02-17  Jim Meyering  <jim@meyering.net>

        * Version 5.2.0.

        `make check' from a build inside a chroot environment would fail
        * tests/help-version: Specify an argument (`/') for df, in the
        unusual event that there is no valid entry in /etc/mtab.
        Likewise for id: add the -u option, so we don't get spurious
        failures when there are no user or group names.
        Patch by Tim Waugh.

        * src/sort.c (usage) [-u]: Add punctuation so that the description in
        the help2man-generated (line-joined) man page is more readable.
        Reported by Tim Waugh.
        [-T]: Add a semicolon, for the same reason.

2004-02-15  Jim Meyering  <jim@meyering.net>

        * Makefile.am (dist-hook): Qualify target with $(srcdir)/ prefix.

2004-02-11  Jim Meyering  <jim@meyering.net>

        * tests/Makefile.am.in ($(srcdir)/Makefile.am): Use more portable
        $(srcdir)/../Makefile.am.in, rather than $<.
        Suggestion from Michael Elizabeth Chastain.

        * config/install-sh: Make this script executable.
        * Makefile.am (dist-hook): New target, to ensure that config/install-sh
        is executable.  Otherwise, on systems that lack a suitable install
        binary, `make install' would fail, because of the way this script
        is invoked (without `$SHELL ' prefix).
        Reported by Bob Proulx.

2004-02-08  Jim Meyering  <jim@meyering.net>

        * Version 5.1.3.

        * tests/rm/rm5: Avoid triggering a bug in OSF/Tru64's sed
        that would cause an unwarranted test failure.
        * tests/rm/rm3: Likewise.

2004-02-07  Jim Meyering  <jim@meyering.net>

        Remove xstat function pointer member.  The way it was used was not
        portable, since some systems (OSF V5.1, Solaris 2.5.1) provide static
        inline `stat' and `lstat' functions, thus making the tests of
        `xstat == lstat' in copy.c always fail.
        * src/copy.h (struct cp_options) [xstat]: Remove member.
        (XSTAT): New macro.
        * src/copy.c (copy_dir): Set `.dereference' member, not .xstat.
        (copy_internal): Use `XSTAT (x, ...)' in place of `*(x->xstat) (...)'.
        Use `x->dereference == DEREF_NEVER' in place of `x->xstat == lstat'.
        (valid_options): Remove now-obsolete FIXME comments.

        * src/cp.c (re_protect): Use `XSTAT (x, ...)' in place of
        `*(x->xstat) (...)'.
        (do_copy): Declare/use local xstat rather than x->xstat.
        (main): Remove code that set x.xstat.
        * src/mv.c (cp_option_init): Don't initialize xstat member.
        * src/install.c (cp_option_init): Likewise.

        * Makefile.cfg (gnu_ftp_host-alpha, etc.): Un-factor .gnu.org suffix,
        so that emit_upload_commands can use these variables, too.

2004-02-06  Jim Meyering  <jim@meyering.net>

        * tests/rm/deep-1: Remove `du' stack space test.
        Apparently, `ulimit -s N' isn't portable enough.
        This test will be restored (with a guard against losing ulimit)
        in its own file later.

        * tests/rm/deep-1 (deep): Remove progress-style diagnostics,
        since this test doesn't take long enough to merit them.
        Run du on $tmp (the containing dir), not $deep, the full path to leaf.

        * Makefile.maint (signatures): Remove definition.
        Now, automake's gnupload handles this.
        (%.sig: %): Remove now-unused rule.
        (rel-files): Use automake's $(DIST_ARCHIVES), rather than
        `$(distdir).tar.bz2 $(distdir).tar.gz'.
        (emit-upload-commands): Adjust to use gnupload.

2004-02-05  Jim Meyering  <jim@meyering.net>

        * src/system.h (ST_TIME_CMP_NS, ST_TIME_CMP): Remove definitions.
        (ATIME_CMP, CTIME_CMP, MTIME_CMP, TIMESPEC_NS): Likewise.
        Now, those are all defined in timespec.h.
        Include timespec.h.

        * src/date.c: Don't include timespec.h, now that system.h does it.

2004-02-02  Paul Eggert  <eggert@twinsun.com>

        Don't dump core if localtime returns NULL (possible on
        hosts with 64-bit time_t and 32-bit int).
        * src/date.c: Include "inttostr.h".
        (batch_convert, main):
        If time conversion fails, exit with nonzero status.
        (show_date): Return int to report conversion failure.
        Print the time as an int if localtime fails.
        * src/uptime.c: Print "??" if the current clock can't
        be converted by localtime.  This won't happen until the year
        2*31 + 1900, but we don't want to dump core even if the current
        clock has the wrong value.

        * src/stat.c: Include "inttostr.h".
        (human_time): Print the date/time as a number of seconds since the
        epoch if it can't be converted by localtime.  This is better than
        just saying "invalid", and is consistent with what "ls" does.
        Don't dump core if the year has more than 48 digits; this isn't
        possible on any contemporary host, but we might as well do it right.

2004-01-31  Paul Eggert  <eggert@twinsun.com>

        * src/stat.c (human_time): Accept time rather than
        pointer-to-const-time parameter, for clarity.  All callers changed.

2004-02-02  Jim Meyering  <jim@meyering.net>

        * src/stat.c (do_stat): Remove extra trailing newline from
        default formats.  Reported by Nelson H. F. Beebe.

        Print actual fractional seconds in time stamps, not just `.00000000'.
        * src/stat.c (human_time): Add and use new parameter, t_ns.
        (print_stat): Update callers.
        * src/ls.c (TIMESPEC_NS): Remove definition.
        * src/system.h (TIMESPEC_NS): Define here, instead, now that stat.c
        also uses this macro.
        Nelson H. F. Beebe noticed that ls --full-time printed nonzero
        fractional seconds for files on an XFS file system, but that stat's
        fractional seconds were always zero.

2004-01-28  Paul Eggert  <eggert@twinsun.com>

        * src/seq.c (print_numbers): Use 'double' for loop index, not
        'int', to avoid problems with integer overflow.  On almost all
        machines 'double' works in every case where 'int' works, and
        it works on other cases besides.

2004-01-27  Jim Meyering  <jim@meyering.net>

        * src/seq.c (usage): Mention that if INCREMENT is omitted,
        it defaults to 1, even when FIRST is larger than LAST.
        Reword so as not to exclude the possibility that INCREMENT be zero.

2004-01-25  Jim Meyering  <jim@meyering.net>

        * Version 5.1.2.

        * Makefile.maint (signatures): Comment out definition.

2004-01-23  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (header_regexp): Add exitfail.

        * man/Makefile.am (EXTRA_DIST): Add help2man.
        Reported by Nelson H. F. Beebe.

        * man/Makefile.am (.x.1): Prefix help2man invocation with `$(PERL) --'
        so it works on systems with Perl installed somewhere other than in
        /usr/bin.

        * src/paste.c (paste_parallel): Declare local, chr, to be of type
        `int', not `char', since it must hold EOF.  This bug would make
        paste infloop on some systems.  Test failures reported by
        Nelson H. F. Beebe and Christian Krackowizer.

2004-01-22  Jim Meyering  <jim@meyering.net>

        * tests/rmdir/fail-perm: New file.  Test for just-fixed rmdir bug.
        * tests/rmdir/Makefile.am (TESTS): Add fail-perm.

        * man/help2man: Fix it so using --info-page='coreutils PROG' works.
        * man/Makefile.am (.x.1): Invoke our own (tweaked) copy of help2man.
        Use --info-page='coreutils PROG' option.
        Now, readlink.1 refers the user to `info coreutils readlink'
        rather than to `info readlink'.  Reported by Matt Swift.

2004-01-21  Paul Eggert  <eggert@twinsun.com>

        Exit status cleanup.

        * src/basename.c (usage): Use EXIT_SUCCESS, not 0, for clarity.

        * src/users.c, src/wc.c, src/who.c, src/whoami.c, src/yes.c: Likewise.

        * src/cat.c (usage): Don't bother normalizing exit status
        since the arg is already the correct exit status now.
        * src/cksum.c, src/comm.c, src/csplit.c, src/cut.c,
        * src/dircolors.c, src/expand.c, src/fmt.c, src/fold.c, src/head.c,

        * src/tsort.c, unexpand.c, src/src/uniq.c, src/src/wc.c: Likewise.

        * src/chown.c (main): Removed unused local 'fail'.

        * src/chroot.c (CHROOT_FOUND_BUT_CANNOT_INVOKE, CHROOT_FAILURE):
        Remove.

        * src/chroot.c (main): Initialize exit_failure to EXIT_FAIL.
        * src/env.c, src/nice.c, src/su.c: Likewise.
        * src/nohup.c (main): Likewise, to NOHUP_FAILURE.
        * src/setuidgid.c (main): Likewise, to SETUIDGID_FAILURE.
        * src/expr.c (main): Use initialize_exit_failure rather than
        setting exit_failure directly; this optimizes away redundant
        assignments.
        * src/printenv.c, src/sort.c, src/test.c, src/tty.c: Likewise.

        * src/chroot.c (main): Exit with status 1 rather than 127
        if chroot itself fails, as per documentation.

        * src/chroot.c (main): Use EXIT_ENOENT and EXIT_CANNOT_INVOKE
        rather than roll-your-own symbols or integers.
        * src/env.c (main): Likewise.
        * src/nohup.c (main): Likewise.
        * src/su.c (run_shell): Likewise.

        * src/cp.c (exit_status): Remove static var....
        (main): Making it local here instead.  Use =, not |=, to set it.

        * src/cut.c (FATAL_ERROR, main): Exit with status EXIT_FAILURE,
        not 2, on errors.
        * src/date.c (batch_convert, main): Likewise.
        * src/dd.c (dd_copy): Likewise.
        * src/pr.c (first_last_page, main, getoptarg): Likewise.
        * src/tr.c (main): Likewise.
        * src/date.c (main): Don't assume EXIT_FAILURE == 1, as
        POSIX doesn't require it.
        * src/dd.c (write_output, skip, dd_copy): Likewise.
        * src/df.c (main): Likewise.
        * src/id.c (main): Likewise.
        * src/install.c (main): Likewise.
        * src/ln.c (main): Likewise.
        * src/ls.c (main): Likewise.
        * src/mv.c (main): Likewise.
        * src/shred.c (main): Likewise.

        * src/env.c (main): Exit with status 1, not 2, on errors detected
        by env proper.
        * src/hostname.c (main): Likewise.
        * src/nl.c (main): Likewise.
        * src/stty.c (main): Likewise.

        * src/expr.c (EXPR_FAILURE): Renamed from EXPR_ERROR, for
        consistency with the other programs' naming conventions.
        All uses changed.

        * src/factor.c (main): Do not report a usage error simply
        because stdin has bad numbers.

        * src/id.c (problems): Now a boolean int, not a counter,
        so that we don't have to worry about int overflow.  All uses changed.
        * src/touch.c (err): Likewise.

        * src/md5sum.c (main): Use int, not size_t, to store boolean int.

        * src/mkfifo.c (main): Exit with status 1, not 4, if not implemented.
        * src/mknod.c: Likewise.

        * src/nice.c (main): Exit with status EXIT_FAIL, not EXIT_FAILURE,
        on error; this is in case EXIT_FAILURE is unusual.
        * src/su.c (main): Likewise.

        * src/nohup.c (NOHUP_FOUND_BUT_CANNOT_INVOKE): Remove; all uses
        changed to EXIT_CANNOT_INVOKE.

        * src/printenv.c (PRINTENV_FAILURE): New constant.
        (main): Exit with status PRINTENV_FAILURE, not EXIT_FAILURE, on
        command-line syntax problems.

        * src/rmdir.c (remove_parents): Don't set 'fail' to a negative number.
        (main): Avoid integer overflow when seeing whether errors occurred.

        * src/seq.c (print_numbers): Now returns void, not (zero) int.
        All callers changed.
        (main): Remove unused local variable 'errs'.  Always exit successfully
        if we reach the end.

        * src/setuidgid.c (SETUIDGID_FAILURE): Renamed from FAIL_STATUS,
        for consistency with other programs here.  All uses changed.
        (main): Use 'error' to exit rather than invoking 'exit' here.

        * src/sort.c: Don't include <assert.h>.
        (SORT_OUT_OF_ORDER,  SORT_FAILURE): Now enums, not macros.
        (usage): Don't use 'assert'.
        (main): Remove redundant assignment to exit_failure.

        * src/system.h (EXIT_FAIL, EXIT_CANNOT_INVOKE, EXIT_ENOENT):
        New enum values.
        (initialize_exit_failure): New inline function.
        Include exitfail.h here, since we refer to exit_failure.
        All callers changed to not include exitfail.h.

        * src/tty.c (TTY_FAILURE, TTY_WRITE_ERROR): New enum values;
        substitute them for the corresponding integer constants.

        * tests/help-version (expected_failure_status_date): Remove, as
        'date' is now normal.
        (expected_failure_status_nohup): New var.

2004-01-21  Jim Meyering  <jim@meyering.net>

        * tests/touch/relative: Remove `command' syntax.
        Thanks to Nelson H. F. Beebe and Paul Eggert.

        * tests/touch/relative: Test only year/month/day, not hours/min/sec,
        so as to avoid problems with systems using TAI clocks.
        Although it's no longer necessary, set TZ=UTC0 also for the
        initial touch command.  Reported by Paul Jarc here:
        http://article.gmane.org/gmane.comp.gnu.core-utils.bugs/1504

2004-01-20  Diego Biurrun  <diego@biurrun.de>

        * src/dircolors.hin: Add .mov to the list of media files.

2004-01-19  Paul Eggert  <eggert@twinsun.com>

        * tests/touch/relative: Use TZ=UTC0, not TZ=utc (which isn't
        portable).  Problem reported by Christian Krackowizer.  Also, use
        +0000 rather than +0 to specify a time zone, as the documentation
        requires four digits.

2004-01-19  Jim Meyering  <jim@meyering.net>

        * tests/mv/hard-4: Run envvar-check in case SIMPLE_BACKUP_SUFFIX is set.
        * tests/mv/backup-is-src: Likewise.
        Problem reported by Peter Horst

2004-01-17  Jim Meyering  <jim@meyering.net>

        * announce-gen (print_changelog_deltas): Use .sig suffix, not .asc.

        * Version 5.1.1.

2003-12-15  Paul Eggert  <eggert@twinsun.com>

        * NEWS, doc/coreutils.texi: touch -r and -d can now both be specified,
        with -r specifying the origin for -d.
        * src/touch.c (flexible_date): Remove static var.
        (get_reldate): New function.
        (main): Use it, to implement this new behavior.

2004-01-16  Jim Meyering  <jim@meyering.net>

        * tests/touch/relative: New test for the above.
        * tests/touch/Makefile.am (TESTS): Add relative.

2004-01-13  Jim Meyering  <jim@meyering.net>

        * src/system.h: Include contents of sys2.h.
        * src/sys2.h: Remove file.
        * src/Makefile.am (noinst_HEADERS): Remove sys2.h.

        * Use automake-1.8.2.  Regenerate dependent files.

        * Update to gettext-0.13.1.
        * configure.ac: Use gettext-0.13.1.
        * .x-sc_space_tab: Add m4/po.m4 to the list of exceptions.

2004-01-12  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (%.sig): Use .sig suffix rather than .asc.

        * Makefile.maint (po-check): Ensure that cvsu works before using it.
        Reported by Alexandre Duret-Lutz.

        * src/tail.c (main): Warn about following stdin only when it's a tty.

        * configure.ac: Use gl_DEFAULT_POSIX2_VERSION.

2004-01-10  Jim Meyering  <jim@meyering.net>

        * tests/misc/stat-fmt: Use backticks, not `$()' notation.

2004-01-09  Jim Meyering  <jim@meyering.net>

        * configure.ac: Quote underquoted `jm_DUMMY_1' to avoid new warning.

2004-01-08  Jim Meyering  <jim@meyering.net>

        * src/stat.c (human_fstype): Use %lx, not %x format for `unsigned long'.
        From Andreas Schwab.

        * tests/Makefile.am (TESTS_ENVIRONMENT): Remove `/vg' (prerelease test
        remnant) from PATH component.  That would cause tests in this directory
        not to run the just-built binaries, but rather whatever happened
        to be in one's PATH.  Reported by Christian Krackowizer.

2004-01-04  Jim Meyering  <jim@meyering.net>

        * src/csplit.c (new_control_record): Use x2nrealloc
        rather than xrealloc.

        * src/cp.c (re_protect): Use ASSIGN_STRDUPA rather than
        alloca and strcpy.
        (make_path_private): Likewise.

2004-01-03  Jim Meyering  <jim@meyering.net>

        * src/paste.c: Use `bool' (not int) as the type for a few
        global variables.
        (collapse_escapes): Rewrite to set globals rather than modifying
        its parameter.
        Use size_t (not int) for all counters and related index variables.
        (paste_parallel): Remove needless complexity of
        using xrealloc in the loop;  just allocate the buffers up front.
        Free the two temporary buffers.
        Move declarations of locals `down' into scope where used.
        (paste_serial): Remove `register' attributes.
        (main): Simplify delim-related code.
        Free `delims', now that it's malloc'd.

2004-01-02  Jim Meyering  <jim@meyering.net>

        * src/chroot.c: Include "quote.h".
        (CHROOT_FOUND_BUT_CANNOT_INVOKE, CHROOT_FAILURE): Define.
        (main): Exit with status of 127, not 1, for too-few-args,
        chroot failure, or chdir failure.
        Give a better diagnostic upon execvp failure.

        * src/du.c (usage): Mention that, with its current meaning,
        -H is deprecated.

        * src/tail.c (main): Warn about following stdin when it's a tty.
        Fail when following by name but no names are specified.

2003-12-30  Jim Meyering  <jim@meyering.net>

        * src/fold.c (main): Use memcpy, not strcpy.

        * src/copy.c (copy_internal): Use ASSIGN_STRDUPA rather than
        alloca and strcpy.

2003-12-28  Jim Meyering  <jim@meyering.net>

        * src/unexpand.c (n_tabs_allocated): New global.
        (add_tabstop): Use x2nrealloc rather than xrealloc.
        * src/expand.c: Likewise.

        * tests/misc/expand: New file.
        * tests/misc/Makefile.am (TESTS): Add expand.

        * src/sort.c (add_temp_dir): Use x2nrealloc rather than xrealloc.
        (fillbuf): Use x2nrealloc rather than xrealloc.
        (sort): Use xnmalloc rather than xmalloc.
        (main): Likewise.

2003-12-27  Jim Meyering  <jim@meyering.net>

        * src/tee.c (tee): Use xnmalloc rather than xmalloc.

2003-12-29  Paul Eggert  <eggert@twinsun.com>

        * NEWS: Remove support for join -j1 FIELD, -j2 FIELD, and -o LIST1
        LIST2 in POSIX 1003.1-2001 hosts, as required by POSIX.

        * doc/coreutils.texi (join invocation): Remove documentation
        accordingly.  Document that -t makes all separators significant.

        * src/join.c: Include posixver.h.
        (obsolete_usage): New var.
        (longopts): Put obsolete options first.
        (OBSOLETE_LONG_OPTIONS): New constant.
        (get_option, add_file_name): New functions.
        (main): Use them to support new behavior.
        (usage): Remove documentation for -j1 FIELD and -j2 FIELD.
        Do not mark -j FIELD as obsolescent; it is longstanding
        UNIX tradition and is a valid extension to POSIX.

        * tests/join/Test.pm (tv): Avoid obsolete -o usage.

2003-12-28  Paul Eggert  <eggert@twinsun.com>

        * src/join.c (add_field_list): Don't use alloca with unbounded
        size; just modify the argument, which is no longer const *.

        Various other minor cleanups, mostly to avoid the need for casts.

        (extract_field): Renamed from ADD_FIELD, as it's now a function.

        (struct field.beg): Now char *, not unsigned char const *.  All
        uses changed.  It shouldn't be const since xmemcoll writes on its
        arguments.
        (extract_field): Likewise, for 2nd arg.
        (keycmp): Remove now-unnecessary cast of xmemcoll args.

        (is_blank): New function, to avoid need to cast arg to unsigned char.
        (extract_field): Use it.

        (xfields): Rewrite pretty much from scratch.

        (hard_LC_COLLATE): Now bool, not int.
        (get_line, getseq, add_field_list): Now returns bool, not int.
        (decode_field_spec, add_field_list): Return true on success (not
        false), for consistency with the rest of the code.  All uses changed.

        (tab): Now char, not unsigned char.  This wasn't 100% necessary
        but is slightly cleaner.
        (prjoin): Hoist (tab ? tab : ' ') expression, to help the compiler.

        (empty_filler): Now const *.

        (make_blank): Remove; wasn't needed.  Remove all calls.
        (main): Don't set uni_blank.nfields; zero is fine.

2003-12-27  Jim Meyering  <jim@meyering.net>

        * src/join.c: Include "quote.h".
        (min, max): Remove definitions.
        Make a few function parameters and corresponding
        locals `const'.  Use bool for boolean variables.
        Use size_t (not int) for all counters and related index variables.
        (prjoin): Remove now-useless assertion.
        (string_to_join_field): New function.
        (main): Accept join fields as large as SIZE_MAX.
        (keycmp): Rename `min' to MIN and max to MAX.

2003-12-26  Jim Meyering  <jim@meyering.net>

        fold -s didn't work on e.g., alpha-based systems.
        * src/fold.c (fold_file): Adjust types (int->size_t) so that using
        x2nrealloc works properly on systems with differing sizes for int
        and size_t.  Reported by Nelson Beebe.

        * src/fold.c: Use `bool' (not int) as the type for a few
        global variables.

2003-12-23  Paul Eggert  <eggert@twinsun.com>

        * src/ls.c (length_of_file_names_and_frills):
        Remove forward decl; not needed.
        (print_file_name_and_frills, length_of_file_name_and_frills):
        With -m, don't output spaces before inum or size.
        (print_with_commas): Don't output space just before newline.

2003-12-24  Jim Meyering  <jim@meyering.net>

        * tests/ls/Makefile.am (TESTS): Add m-option.

        * tests/Makefile.am (root-hint): Tweak wording.

        * src/du.c: Accept new option (-0, --null) that makes it so each
        output line is NUL-terminated rather than newline-terminated.

        * src/dd.c (apply_translations): Don't prohibit conv=unblock,sync.
        Reported by Volker Paul.
        * tests/dd/Makefile.am (TESTS): Add unblock-sync.

        (main): Make fts use FTS_TIGHT_CYCLE_CHECK.
        (main) [DU_DEBUG]: Accept -d option.

2003-12-18  Jim Meyering  <jim@meyering.net>

        * src/ls.c (format_user): Increment dired_pos via two statements,
        `dired_pos += width; dired_pos++;' rather than one,
        `dired_pos += width + 1;' since the latter could conceivably overflow.
        (format_group): Likewise.
        From Paul Eggert.

        * configure.ac: Require automake-1.8.

2003-12-12  Jim Meyering  <jim@meyering.net>

        smaller and more consistent with other functions.
        (format_user): Output to stdout, not to a buffer, so that we
        don't have to worry about buffer overrun.  Update dired_pos.
        (print_long_file): Don't put owner, group, author into buffer;
        just print them directly.  Don't assume link counts and
        major and minor numbers fit into unsigned long int.
        * tests/cp/same-file, tests/mv/part-symlink: Don't assume that
        'ls' output is fixed-width.

2003-12-02  Jim Meyering  <jim@meyering.net>

        * src/md5sum.c: Include sha1.h (reflect renaming: sha.h -> sha1.h.

2003-11-24  Paul Eggert  <eggert@twinsun.com>

        Parse floating-point operands and options in the C locale.
        POSIX requires this for printf, and we might as well be
        consistent elsewhere (tail, sleep, seq).

        * src/printf.c: Remove decls of strtod, strtol, strtoul; no longer
        needed now that we assume C89.  Include "c-strtod.h".
        (xstrtod): Call c_strtod, not strtod.
        * src/sleep.c: Include "c-strtod.h".

        * src/join.c (usage): Mention that FILE1 and FILE2 must be sorted
        on the join fields.  Suggestion from Bruce Robertson.

2003-11-18  Jim Meyering  <jim@meyering.net>

        `od -c -w9999999' could segfault
        * src/od.c (dump): Use xnmalloc/free, not alloca.

2003-11-16  Jim Meyering  <jim@meyering.net>

        * Use autoconf-2.59.  Regenerate dependent files.

        * tests/du/hard-link: Minor tweak: use mkdir -p.

        Fix read-from-free'd-buffer error detected by valgrind.
        * src/csplit.c (remove_line): Don't return a pointer to data in
        a freed buffer.  Instead, arrange to free the buffer on the
        subsequent call.

        * tests/misc/csplit: New test for above fix.

2003-11-11  Jim Meyering  <jim@meyering.net>

        * src/ls.c (extract_dirs_from_files): Avoid useless copy operations.

        * configure.ac: Require automake-1.7.8.

2003-11-09  Jim Meyering  <jim@meyering.net>

        whether it's leaked or not.
        * src/who.c (who): Likewise for `utmp_buf'.

2003-11-05  Paul Eggert  <eggert@twinsun.com>

        Fix 'cut' problems with size_t overflow and unsigned int.
        More generally, resize integer variables to fit use more precisely.
        * src/cut.c (ADD_RANGE_PAIR): Remove unnecessary parens.

        Use bool, not int, for booleans.
        (set_fields): Allocate zeroed byte array with xzalloc, not xcalloc.

2003-11-05  Paul Eggert  <eggert@twinsun.com>

        * man/Makefile.am (check-programs-vs-x):
        Work even if $(programs) contains '$'.
        Work even if 'missing=1' in environment.
        Don't report an error simply because $(programs) outputs nothing.

2003-11-05  Jim Meyering  <jim@meyering.net>

        * Use autoconf-2.58.  Regenerate dependent files.

        * src/tr.c (spec_init): Fix typo in last change.

        * src/sys2.h (case_GETOPT_VERSION_CHAR): Cast NULL to `(char *)' in

        * src/tr.c (append_normal_char, append_range, append_char_class)
        (append_repeated_char, append_equiv_class, spec_init): Use `sizeof *var'

        * tests/chgrp/basic: Do `set +x' before starting the subshell
        from which we invoke chgrp.  Otherwise, the output from the

        Reported by Russel Coker via Michael Stone.

2003-10-19  Jim Meyering  <jim@meyering.net>

        chmod now uses fts to perform a directory traversal when -R is

        first argument of mk-script.
        ($(srcdir)/Makefile.am): Likewise.  Prepend $(srcdir) to target.

2003-10-17  Jim Meyering  <jim@meyering.net>

        * src/mv.c (usage): Tweak descriptions of -i and -f so that the
        generated `man' page is more readable.  Suggestion from Dan Jacobson.

        * src/chown-core.c (change_file_owner): Handle the cases in
        which fts_info indicates an error with the given entry.

        * src/du.c (main): Simply assign to bit_flags.
        Don't bother with bit arithmetic.

        * tests/chmod/no-x: New file.
        * tests/chgrp/no-x: New file.
        * tests/chmod/Makefile.am (TESTS): Add no-x.
        * tests/chgrp/Makefile.am (TESTS): Likewise.

        * src/du.c: Include "xfts.h".
        (du_files): Use xfts_open, rather than fts_open.
        * src/chown-core.c (chown_files): Likewise.

2003-10-16  Jim Meyering  <jim@meyering.net>

        * src/chgrp.c (main): Simply assign to bit_flags.
        Don't bother with bit arithmetic.
        * src/chown.c (main): Likewise.
        Rename a couple of local variables.
        Remove unnecessary casts.

        * src/tail.c (start_bytes): Rename local, remainder, to avoid
        gcc's warning about shadowing a global.

2003-10-15  Jim Meyering  <jim@meyering.net>

        chown and chgrp now accept POSIX-mandated -H, -L, -P options and
        use fts to perform a directory traversal when -R is specified.
        Before, they operated on full path names, and as such would
        encounter the PATH_MAX (often 4096) limit.
        They are more efficient.  For example, before, chgrp -R would
        take almost 5 seconds to change about 2000 directories and fail
        (with `File name too long'), while now it succeeds on a hierarchy
        of depth 20,000 in 1/10 the time.

        * src/chown.c: Include "userspec.h" and "fts_.h".
        (WRITTEN_BY): Add my name.
        (getpwnam, getgrnam, getgrgid): Remove declarations.
        (endpwent): Remove definition.
        (usage): Update.
        (main): Handle new options.
        Call new function, chown_files rather than change_file_owner.

        * src/chgrp.c: Include "fts_.h".
        (WRITTEN_BY): Add my name.
        (MAXUID, MAXGID): Remove definitions.  Use GID_T_MAX instead of
        the latter.
        (usage): Update.
        (main): Handle new options.
        Call new function, chown_files rather than change_file_owner.

        Rewrite to iterate through hierarchies using fts rather than
        via explicit recursion.
        * src/chown-core.c: Include "fts_.h"
        (change_file_owner): Rewrite to use FTS* and FTSENT* and to operate
        on a single file at a time.
        (chown_files): New function.
        * src/chown-core.h [enum Dereference_symlink]: Remove declaration.
        [struct Chown_option] (recurse, force_silent): Change type to `bool'.
        [struct Chown_option] (dereference): Remove member with ambiguous name.
        [struct Chown_option] (affect_symlink_referent): New member.
        (chown_files): New prototype.

        * tests/chgrp/recurse: Update tests accordingly.
        * tests/chgrp/posix-H: New tests for the above.
        * tests/chgrp/Makefile.am (TESTS): Add posix-H.

        * src/ln.c (usage): Clarify that --directory, -d, -F probably won't
        work even for superuser.  Suggestion from Dan Jacobson.

2003-10-14  Paul Eggert  <eggert@twinsun.com>

        Fix some number-parsing bugs, e.g., "head -n 100k@" wasn't
        properly diagnosed.
        * lib/human.c, lib/xstrtoimax.c, lib/xstrtol.c, lib/xstrtol.h,
        lib/xstrtoul.c, lib/xstrtoumax.c: Sync with gnulib.
        * src/sort.c (parse_field_count): Handle the case where overflow
        and invalid suffix char are both reported.

2003-10-14  Jim Meyering  <jim@meyering.net>

        * src/ls.c (decode_switches) [TIOCGWINSZ]: Comment out the
        warning-inducing test, ws.ws_col <= SIZE_MAX, since it was always
        true on Linux.

2003-10-13  Paul Eggert  <eggert@twinsun.com>

        Fix to avoid a denial-of-service attack if the display width is
        enormous.  Also, clean up the code a bit by removing duplicate code.

        * src/ls.c (init_column_info): Remove forward decl; no longer needed.
        (calculate_columns): New function, that contains code that used
        to be common to print_many_per_line and print_horizontal.
        (print_many_per_line, print_horizontal): Use it.
        (decode_switches): Set max_idx here, not in calculate_columns.
        (print_current_files): Don't call init_column_info; calculate_columns
        now does that.
        (init_column_info): Don't allocate a lot more space than is needed
        to represent the current set of files.  Allocate all the new
        size_t cells in one call to xnmalloc, rather than a row at a time.

2003-10-13  Jim Meyering  <jim@meyering.net>

        * src/ls.c (init_column_info): Add another FIXME comment.

2003-10-13  Paul Eggert  <eggert@twinsun.com>

        Fix address-arithmetic bug in 'ls', reported by Georgi Guninski.
        Remove several arbitrary limits on hosts where int cannot represent
        all size_t values.

        * src/ls.c (struct bin_str.len, length_of_file_name_and_frills, indent,
        nfiles, files_index, tabsize, line_length, struct column_info.line_len,
        struct column_info.col_arr[0], max_idx):
        Now size_t, not int.
        (get_funky_string): Return bool indicating success, instead of
        a negative count to indicate failure.  Store number of columns
        through new parameter OUTPUT_COUNT; that way, they can never
        go negative.  Change equals_end from int to bool.  All uses
        changed.
        (struct column_info.valid_len): Now bool, not int.  All uses changed.
        (dired_dump_obstack, get_funky_string, clear_files,
        extract_dirs_from_files, print_current_files,
        print_many_per_line, print_horizontal, init_column_info,
        put_indicator, length_of_file_name_and_frills,
        print_with_commas): Use size_t, not int, for local variables
        that count sizes.
        (decode_switches): Decode sizes using xstrtoul, not xstrtol.
        Check for TIOCGWINSZ returing negative values (or values greater
        than SIZE_MAX!).
        (visit_dir, main, parse_ls_color, queue_directory, add_ignore_pattern,
        init_column_info):
        Use xmalloc and xnmalloc, not XMALLOC.
        (gobble_file): Use xnrealloc, not XREALLOC.
        (print_color_indicator): Remove now-unnecessary cast to size_t.

2003-10-12  Paul Eggert  <eggert@twinsun.com>

        * tests/du/no-x: Change wording of diagnostic to match latest du.c.
        * tests/sort/sort-tests: Remove from CVS; assume that people
        brave enough to check coreutils out from CVS can rebuild it.

2003-10-12  Jim Meyering  <jim@meyering.net>

        New options: --preserve-root and --no-preserve-root.
        * src/chmod.c (change_file_mode): Honor new option.
        (change_file_mode): Strip trailing slashes on directory
        argument passed to change_dir_mode.
        (get_root_dev_ino): New function.
        (main): Initialize global, root_dev_ino.

        * src/copy.c (copy_internal): Don't #ifdef-out simple uses of
        S_ISLNK or S_ISSOCK.  The S_IS* macros are guaranteed to be defined
        via system.h.
        * src/chmod.c (change_file_mode): Likewise.

2003-10-08  Jim Meyering  <jim@meyering.net>

        * src/csplit.c (main): Remove obsolete FIXME.

2003-10-07  Jim Meyering  <jim@meyering.net>

        * Use automake-1.7.8.  Regenerate dependent files.

2003-09-29  Paul Eggert  <eggert@twinsun.com>

        csplit cleanup.

        * doc/coreutils.texi (csplit invocation):
        The regexp offset need not have a sign; POSIX requires support
        for signless offets.

        Be more careful about int widths.  For example, remove some
        arbitrary limits by replacing 'unsigned' with 'size_t',
        'uintmax_t', etc.  Use standard bool rather than a homegrown type.
        * lib/Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c.
        * src/csplit.c (FALSE, TRUE, boolean): Remove.  All uses changed
        to <stdbool.h> usage.
        (struct control): offset is now intmax_t, not int.
        repeat_forever is now bool, not int.
        (struct cstring): len is now size_t, not unsigned int.
        (struct buffer_record): bytes_alloc, bytes_used, num_lines are now
        size_t, not unsigned.  start_line, first_available are now
        uintmax_t, not unsigned.
        (hold_count, control_used): Now size_t, not unsigned.
        (last_line_number, current_line, bytes_written):
        Now uintmax_t, not unsigned.
        (save_to_hold_area, red_input, keep_new_line, record_line_starts,
        create_new_buffer, get_new_buffer, load_buffer, find_line,
        process_regexp, split_file, new_control_record, extract_regexp,
        get_format_width, get_format_prec, max_out):
        size args, locals, and returned values are now size_t, not unsigned
        or int.
        (get_first_line_in_buffer, find_line, write_to_file,
        handle_line_error, process_line_count, regexp_error, process_regexp,
        split_file):
        File line, byte, and repetition counts are now uintmax_t, not unsigned.
        (check_for_offset): Don't require a sign before the offset.
        Use xstrtoimax to do the real work.
        (extract_regexp): Remove harmful cast of size to unsigned.
        256 -> 1<<CHAR_BIT, for clarity.
        (get_format_flags): Return at most 3, to avoid worries about overflow.

        (bytes_to_octal_digits): Remove.

        (cleanup): Don't check whether output_stream is NULL, since
        close_output_file does that for us.

        (new_line_control, create_new_buffer): Use "foo *p = xmalloc
        (sizeof *p);" instead of the more long-winded alternatives.

        (get_new_buffer): Use O(1) algorithm for resizing a buffer
        to a much larger size, instead of an O(N) algorithm.

        (process_regexp): Use plain NULL rather than casted 0.

        (make_filename): Use %u, not %d, to format unsigned file number.

        (new_control_record): Use xrealloc exclusively, since it handles
        NULL reliably.

        (extract_regexp): Change misspelled word in diagnostic.

        (get_format_width): Even if a minimum field width is specified,
        allow room for enough octal digits to represent the value of
        the maximum representible integer.  This fixes a potential
        buffer overrun.  Calculate this room at compile-time, not
        at run-time; this removes the need for bytes_to_octal_digits.
        Check for overflow; this removes a FIXME.

        (get_format_prec): Don't allow precision to be signed; it's
        not ANSI.  Check for overflow.  Remove hardcoded "11" as
        default precision; this fixes a potential buffer overrun
        on hosts with wider size_t.

        (get_format_conv_type): Change local variable to be of type
        unsigned char, not int; this removes a potential subscript
        violation on hosts where char is signed.

        (max_out): Replace "for (;*p;)" with more-standard "while (*p)".
        Allow "%%" in format.  Don't overflow when
        counting lots of percents.

        (usage): Default sprintf format is %02u, not %d.

2003-10-05  Jim Meyering  <jim@meyering.net>

        * src/chown-core.c (change_file_owner): Remove set-but-not-used local.

        * src/du.c (du_files): Mark diagnostic for translation.

2003-10-04  Jim Meyering  <jim@meyering.net>

        * src/du.c (du_files): Ignore any failure of fts_close.
        Give better diagnostics for failed fts_open.

        * src/du.c (MAX_N_DESCRIPTORS): Remove now-unused definition.

        Deprecate existing use of -H (aka --si).
        * src/du.c (enum) [HUMAN_SI_OPTION]: New member.
        [long_options]: Use HUMAN_SI_OPTION, not 'H'.
        (main): Warn that the meaning of -H will soon change to be
        POSIX compliant.

2003-10-03  Jim Meyering  <jim@meyering.net>

        * src/du.c: Accept --no-dereference (-P).

2003-10-02  Jim Meyering  <jim@meyering.net>

        * tests/du/trailing-slash: Adjust for slightly different output.

        Rewrite du.c to use fts.
        * src/du.c: Include "fts_.h", not ftw.h.
        (opt_dereference_arguments, arg_length, suffix_length): Remove globals.
        (IS_FTW_DIR_TYPE): Remove definition.
        (IS_DIR_TYPE): Define.
        (is_symlink_to_dir): Remove now-unnecessary function.
        (process_file, du_files): Rewrite to use fts.

        * tests/du/inaccessible-cwd: Ensure that even when run from an
        inaccessible directory, du can still operate on accessible
        directories elsewhere.
        * tests/du/Makefile.am (TESTS): Add inaccessible-cwd.

        * tests/rm/deep-1: Ensure that du can process a hierarchy
        of depth 400 while using no more than 50KB of stack space.

2003-10-01  Akim Demaille  <akim@epita.fr>

        * announce-gen (print_news_deltas): New function, extracted from main.
        (main): Make `news_file' an array.
        Use '...=s' => \@var for --news and --url-directory specs.
        Before there were a couple of portability problems.

2003-09-28  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (sc_cast_of_alloca_return_value): New rule.
        (syntax-check-rules): Add it.

        * src/copy.c: Remove unnecessary cast of alloca, since now it's
        guaranteed to be (void *).
        * src/cp.c: Likewise.
        * src/join.c: Likewise.
        * src/ln.c: Likewise.

2003-09-27  Jim Meyering  <jim@meyering.net>

        Don't exhaust virtual memory when processing large inputs.
        Fix this by removing csplit's internal free-list management;
        instead rely on malloc for that.

        * src/csplit.c (free_list): Remove global.
        (clear_all_line_control): Remove function.
        (get_new_buffer): Always use create_new_buffer to obtain a
        new buffer, rather than searching free_list.
        (free_buffer): Just call free.
        Reported by Nikola Milutinovic.

2003-09-26  Jim Meyering  <jim@meyering.net>

        * man/rm.x: Also list `chattr' in SEE ALSO section.
        Suggestion from Mark Hubbart.

2003-09-25  Jim Meyering  <jim@meyering.net>

        * configure.ac: Don't invoke AC_AIX or AC_MINIX explicitly, now
        that we use gl_USE_SYSTEM_EXTENSIONS, since it AC_REQUIREs them.

        * Use autoconf-2.57d.  Regenerate dependent files.

2003-09-24  Jim Meyering  <jim@meyering.net>

        Minor efficiency tweak.
        * src/ln.c (PATH_BASENAME_CONCAT): Use memcpy rather than strcpy.
        (do_link): Likewise.

2003-09-23  Jim Meyering  <jim@meyering.net>

        * src/paste.c (paste_serial): Save errno after input error,
        to report proper errno value.
        Based on a patch from Paul Eggert.

        * src/tee.c (tee): Adjust fwrite arguments so that the return
        value is the number of bytes written.

2003-09-16  Paul Eggert  <eggert@twinsun.com>

        Don't assume ferror sets errno.  Bug reported by Bruno Haible.

        * src/comm.c (compare_files): Save errno after input error,
        to report proper errno value.
        * src/fold.c (fold_file): Likewise.
        * src/od.c (check_and_close, skip, read_char, read_block): Likewise.
        * src/unexpand.c (unexpand): Likewise.

        * src/csplit.c (close_output_file): Don't report bogus errno value
        after ferror discovers an output error.  We don't know the proper
        errno value, since it might have been caused by any of a whole
        bunch of calls, and it might have been trashed in the meantime.
        Fixing this problem will require much more extensive changes;
        in the meantime just say "write error".
        * src/od.c (check_and_close, dump, dump_strings): Likewise.
        * src/uniq.c (check_file): Likewise.

        * src/join.c (get_line): Report error right away if I/O fails,

        * src/tee.c (tee): Likewise.
        * src/uniq.c (check_file): Likewise.

        * src/od.c (skip): If a read fails, don't retry it later, so
        that we report the proper errno.

        * src/tac.c (tac_mem): Don't return a value; nobody uses it.

        * src/tee.c (tee): Once a write failure has occurred, don't bother
        writing anything more to that stream.

        * src/uniq.c (check_file): Check for ferror (stdout) even if
        ostream == stdout.

        * src/yes.c (UNROLL): Remove.
        (main): Exit immediately when write failure is detected.
        Simplify code by assigning to argv when argc == 1.

2003-09-21  Paul Eggert  <eggert@twinsun.com>

        * src/ptx.c: Switch encoding from Latin-1 to UTF-8.
        (WRITTEN_BY): Change "Franc,ois" (actually using
        c-with-cedilla in Latin-1) to "F.", so that it's ASCII, as
        xgettext requires.

2003-09-19  Jim Meyering  <jim@meyering.net>

        `du -D symlink-to-dir' would mistakenly omit the slash in
        lines like this: 24     symlink-to-dir/subdir
        * src/du.c (process_file): Fix offset calculation.
        Reported by Jeff Sheinberg as Debian bug #211591;
        http://bugs.debian.org/205251

        * tests/du/deref-args: New file/test for the above.
        * tests/du/Makefile.am (TESTS): Add deref-args.

        * src/du.c (process_file): Remove useless disjunct.

        * src/sys2.h (case_GETOPT_VERSION_CHAR): Rename parameter, Authors,
        to Written_by.
        * nearly all src/*.c files (WRITTEN_BY): Rename from AUTHORS.
        Begin each WRITTEN_BY string with `Written by ' and end it with `.'.
        Mark each WRITTEN_BY string as translatable.

        * who.c, whoami.c, yes.c: Update AUTHORS definition to be a
        comma-separated list of strings and/or update the call to
        parse_long_options so that `AUTHORS, NULL' are the last parameters.
        * src/true.c (main): Append NULL to version_etc argument list.
        * src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.

        * src/sort.c (numcompare): Rename local, logb, to log_b to avoid
        shadowing the math function name.  Also rename loga to log_a.

2003-09-14  Jim Meyering  <jim@meyering.net>

        * src/factor.c (print_factors): Give a separate diagnostic
        for numbers that are too large, but otherwise valid.
        Reported by Dániel Varga.

2003-09-10  Jim Meyering  <jim@meyering.net>

        * Use automake-1.7.7.  Regenerate dependent files.

        * tests/Makefile.am (all_programs): Use ../src/tr -s ' ' '\n' in place
        of `fmt -1'.  Using the just-built tr is a little cleaner.
        Christian Krackowizer reported that HPUX 10.20 doesn't have fmt.
        * man/Makefile.am (programs, check-x-vs-1): Likewise.

2003-09-09  Jim Meyering  <jim@meyering.net>

        * src/copy.c: Alphabetize includes.
        Remove duplicate inclusion of "same.h".

2003-09-08  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (GZIP_ENV): Remove --rsyncable.
        Didn't give enough of a benefit, mainly because it's not yet
        in wide enough use.

        * Version 5.0.91.

        * man/Makefile.am (programs): Use ../src, not $(srcdir)/../src.
        (check-programs-vs-x): Fail if $(programs) is empty.

        * src/remove.c: Add a comment.

2003-09-07  Jim Meyering  <jim@meyering.net>

        * src/remove.c (D_INO, ENABLE_CYCLE_CHECK) [D_INO_IN_DIRENT]:
        Don't define.  These symbols are no longer used.

        * tests/misc/tty-eof: Write ^D as \cD.
        Complete the change of 2003-08-02.

        * Makefile.maint (po-check): Use cvsu, so that a temporary source
        file in lib/ or src/ doesn't induce an unwarranted failure.
        Add a kludge to filter out the sole generated source file that
        also has translatable messages: src/false.c.

2003-09-06  Jim Meyering  <jim@meyering.net>

        * src/tail.c (enum): Add ALLOW_MISSING_OPTION.
        (parse_options): Give a diagnostic for (but still accept) the
        deprecated --allow-missing option.

2003-09-04  Paul Eggert  <eggert@twinsun.com>

        Don't ignore -S if input is a pipe.  Bug report by Michael McFarland in
        <http://mail.gnu.org/archive/html/bug-coreutils/2003-09/msg00008.html>.

        * src/sort.c (sort_buffer_size): Omit SIZE_BOUND arg.  Compute the
        size_bound ourselves. if an input file is a pipe and the user
        specified a size, use that size instead of trying to guess the
        pipe size.  This has the beneficial side effect of avoiding the
        overhead of default_sort_size in that case.  All callers changed.
        (sort): Remove static var size; now done by sort_buffer_size.

2003-09-05  Jim Meyering  <jim@meyering.net>

        * Use automake-1.7.6b and autoconf-2.57b.  Regenerate dependent files.

        * tests/tail-2/tail-n0f: Wait .5 seconds for backgrounded process
        to start, rather than just .1.  Upon failure, print unexpected state.

2003-09-04  Paul Eggert  <eggert@twinsun.com>

        * src/head.c (elide_tail_lines_pipe): Don't assign 0 or
        SAFE_READ_ERROR to tmp->nbytes.
        * src/tail.c (pipe_lines, pipe_bytes): Likewise.

        * src/head.c (struct linebuffer): Change nbytes and nlines
        from unsigned int to size_t.  unsigned int is safe (after the
        2003-09-03 patch) but size_t is cleaner.
        * src/tail.c (struct linebuffer, struct charbuffer): Likewise.
        (pipe_bytes): Likewise for local variable 'i', which was 'int'.

        Standardize on BUFSIZ as opposed to other macro names and values.
        * src/head.c (BUFSIZE): Remove.  All uses changed to BUFSIZ.
        * src/tail.c (BUFSIZ) [!defined BUFSIZ]: Remove.
        stdio.h has always defined it,
        and other code already assumes it's defined.
        * src/tr.c (BUFSIZ) [!defined BUFSIZ]: Likewise.
        (IO_BUF_SIZE): Remove; replace all uses with sizeof io_buf.
        (io_buf): IO_BUF_SIZE -> BUFSIZ.

2003-09-04  Paul Eggert  <eggert@twinsun.com>

        * src/seq.c (step): Default to 1.
        (print_numbers): Allow the output to be empty.
        (main): The default step is 1, even if LAST < FIRST;
        as per documentation.
        * tests/seq/basic (onearg-2): Output should be empty.

2003-09-05  Jim Meyering  <jim@meyering.net>

        * Makefile.cfg (wget_files): Temporarily disable, until master
        versions are restored to ftp.gnu.org.

        * configure.ac (AM_INIT_AUTOMAKE): Specify automake-1.7.6.

        Make seq's --width (-w) option work properly even when the
        endpoint requiring the larger width is negative and smaller than
        the other endpoint.
        * src/seq.c (get_width_format): Include `-' in the set of bytes
        allowed in a `simple' number (no decimal point, no exponent).
        Reported by Patrick Mauritz.

2003-09-02  Paul Eggert  <eggert@twinsun.com>

        * NEWS: sort -t '\0' now uses a NUL tab.
        sort option order no longer matters, unless POSIX requires it.
        * src/sort.c (usage): Say "blanks" instead of "whitespace",
        Similar fixes for many comments.
        (TAB_DEFAULT): New constant, so that we can support NUL as
        the field separator.
        (tab): Now int, not char.  Initialize to TAB_DEFAULT.
        (specify_sort_size): If multiple sizes are specified, use the largest.
        (begfield, limfield): Support NUL tab char.
        (set_ordering): Do not let -i override -d.
        (main): Report an error if incompatible -o or -t options are given.
        Report an error for "-t ''".  Allow "-t '\0'" to specify a NUL tab.

2003-09-05  Jim Meyering  <jim@meyering.net>

        * tests/sort/Test.pm [o2, nul-tab]: New tests for the above.

2003-09-03  Andreas Schwab  <schwab@suse.de>

        Bug report and patch here:
        <http://mail.gnu.org/archive/html/bug-coreutils/2003-09/msg00009.html>
        * src/tail.c (pipe_lines): Don't truncate return value from safe_read.
        * src/head.c (elide_tail_lines_pipe): Likewise.

2003-09-03  Jim Meyering  <jim@meyering.net>

        * src/du.c (AUTHORS): Remove Larry McVoy's name, since the relatively
        small amount of code from him was first moved to lib/human.c, and was
        subsequently rewritten entirely.
        * src/df.c (AUTHORS): Likewise.

2003-08-22  Lawrence Teo  <lcteo@uncc.edu>

        * src/md5sum.c (split_3): Accept the BSD format for generic
        message digest modes.  Currently works with BSD's MD5 and SHA1
        formats since these are the two algorithms presently used in
        coreutils.  Updated comments to reflect this change.
        (bsd_split_3): Updated comments.

        * tests/md5sum/basic-1: New test to make sure that
        `md5sum --check' doesn't accept the BSD SHA1 format (adapted
        from `check-bsd' test in tests/sha1sum/basic-1).

        * tests/sha1sum/basic-1 (check-bsd2, check-bsd3): New tests for
        --check exit status and BSD SHA1 format (adapted from tests
        in tests/md5sum/basic-1).

2003-08-30  Jim Meyering  <jim@meyering.net>

        * src/ln.c (do_link): Use SAME_INODE rather than open-coding it.

        When source and destination arguments refer to the same file, reside
        on a partition (e.g. VFAT) on which distinct names may refer to the
        same directory entry (often due to variations in case), and when the
        link count for the file is 1, mv no longer unlinks the file.  Instead,
        it gives the expected diagnostic that the source and destination are
        the same.  WARNING: this is an incomplete fix.  If the file happens
        to have a link count of 2 or greater, such an erroneous mv command
        will still unlink it.
        Although that is not possible on vfat or umsdos, it is possible on
        other file system types, e.g., ntfs, and hpfs.
        * src/copy.c (same_file_ok): Invoke same_name (which might still
        return false for names that refer to the same directory entry)
        only if the link count is 2 or more.
        * tests/mv/vfat: Show how to demonstrate the above problem.
        This test is not run.
        * tests/mv/Makefile.am (EXTRA_DIST): Add vfat.

2003-08-27  Jim Meyering  <jim@meyering.net>

        * src/who.c: Change meaning of -l from --lookup to --login, per POSIX.
        who's -l option has been eliciting an unconditional warning about
        this impending change since sh-utils-2.0.12 (April 2002).

        * src/paste.c (paste_parallel): Don't output `EOF' (aka -1) as a `char'.
        This would happen for nonempty files not ending with a newline.
        Reported by Dan Jacobson.
        * tests/misc/paste-no-nl: New file.  Test for above-fixed bug.
        * tests/misc/Makefile.am (TESTS): Add paste-no-nl.

        * src/stat.c (print_it): Avoid buffer overrun that would
        occur when the user-specified format string ends with `%'.
        Patch by Tommi Kyntola.
        * tests/misc/stat-fmt: New file.  Test for above-fixed bug.
        * tests/misc/Makefile.am (TESTS): Add stat-fmt.

2003-08-26  Jim Meyering  <jim@meyering.net>

        Apply changes from bison.
        * GNUmakefile (SHELL): Define to `sh', if necessary.
        Add copyright.
        * Makefile.maint (WGETFLAGS): Define to `-C off'.
        Update all uses of $(WGET).

2003-08-22  Akim Demaille  <akim@epita.fr>

        * Makefile.cfg (local-checks-to-skip): New.
        * Makefile.maint (local-check): Rename as...
        (local-checks-available): this.
        (local-check): New.

2003-08-26  Akim Demaille  <akim@epita.fr>

        * announce-gen (print_changelog_deltas): Neutralize "<#" as
        "<\#" to avoid magic from Gnus when posting parts of this script.

2003-08-25  Jim Meyering  <jim@meyering.net>

        * src/stat.c (main): Warn about use of deprecated `-l' option.

2003-08-22  Jim Meyering  <jim@meyering.net>

        * src/stat.c (do_stat): For link count at end of line, use %h format,
        instead of %-5h.  The latter would make stat emit trailing spaces.
        Reported by Dan Jacobson.

2003-08-20  Jim Meyering  <jim@meyering.net>

        * Makefile.am (EXTRA_DIST): Add .x-sc_space_tab .x-sc_sun_os_names

2003-08-19  Jim Meyering  <jim@meyering.net>

        * src/system.h: Include stdlib.h unconditionally,
        as we're now assuming that part of hosted C89.

2003-08-18  Jim Meyering  <jim@meyering.net>

        * src/sys2.h (textdomain, bindtextdomain) [! ENABLE_NLS]: Define away,
        to avoid warnings from gcc.

2003-08-17  Jim Meyering  <jim@meyering.net>

        Avoid unnecessary and sometimes time-consuming hostname lookups.
        * src/who.c (print_user): Use strchr, not strrchr.
        * src/pinky.c (print_entry): Likewise.
        Patch by Michael Stone.
        This fixes a typo I introduced in who-users.c on 1996-02-23.

        * Makefile.maint (makefile-check): Add 0-9 to the range of characters
        disallowed between `@...@'.

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        * configure.ac (fu_cv_sys_truncating_statfs): Remove; now
        done by gnulib .m4 files.
        (jm_DUMMY_1): Require gl_READUTMP, not jm_PREREQ_READUTMP.
        * src/sys2.h (strtoull): Remove unused declaration.

2003-08-16  Jim Meyering  <jim@meyering.net>

        * man/Makefile.am (.x.1): Ensure that generated PROGRAM.1 files
        are read-only.

        * src/tail.c (tail_lines): Fix a potential (but very hard to exercise)
        race condition bug.  The bug would be triggered when tailing a file
        with file pointer not at beginning of file, and where the file was
        truncated to have a length of less than the initial offset at just
        the right moment (between the two lseek calls in this function).

        An invalid initial value for *read_pos would result in
        `tail -n0 -f FILE' and `tail -c0 -f FILE' doing what amounted to a
        busy-wait rather than sleeping between iterations.  The bug manifests
        itself only when tailing regular files that are initially nonempty.
        * src/tail.c (tail_bytes): Set *read_pos to new file offset after
        each xlseek call.
        (tail_lines): Likewise, after lseek calls.
        Reported by Nick Estes.  See http://bugs.debian.org/205251 for details.
        * tests/tail-2/tail-n0f: New file.  Test for above fix.
        * tests/tail-2/Makefile.am (TESTS): Add tail-n0f.

2003-08-15  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (sc_space_tab): Use exclusion list in separate file.
        (sc_sun_os_names): Likewise.
        * .x-sc_space_tab, .x-sc_sun_os_names: New files.

        * man/help2man: Remove some SPACEs before TAB.

2003-08-14  Paul Eggert  <eggert@twinsun.com>

        * Makefile.maint (LC_ALL): Set to C.
        * man/Makefile.am (ASSORT): New var.
        (check-x-vs-1, programs): Use it.
        * src/Makefile.am (ASSORT, check-README, ../AUTHORS): Likewise.
        * tests/Makefile.am (ASSORT, all_programs): Likewise.

2003-08-11  Jim Meyering  <jim@meyering.net>

        fold -s -wN would infloop for N < 8 with TABs in the input.
        E.g., this would not terminate: printf 'a\tb' | fold -w2 -s
        * src/fold.c (fold_file): Move contents of `else'-block
        out of conditional so it's used also for --spaces (-s).
        * tests/misc/fold: Test for the above fix.
        * tests/misc/Makefile.am (TESTS): Add fold.

2003-08-10  Jim Meyering  <jim@meyering.net>

        * src/nice.c [!NICE_PRIORITY]: Include <sys/resource.h> after
        system.h so the types from time.h and sys/time.h are available.
        It appears that this is necessary for OpenBSD, NetBSD, and
        Darwin 6.5 (MacOS 10.2.5).  Reported by Nelson Beebe.

2003-08-06  Paul Eggert  <eggert@twinsun.com>

        * NEWS: Add support for setting file timestamps to microsecond
        resolution, on hosts that support this.
        * src/copy.c, src/cp.c, src/install.c, src/touch.c: Include utimens.h.
        * src/copy.c (copy_internal):
        Set file timestamps with utimens, not utime.
        * src/cp.c (re_protect): Likewise.
        * src/install.c (change_timestamps): Likewise.
        * src/touch.c (newtime, touch, main): Likewise.

2003-08-09  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (sc_sun_os_names): New rule based on a regexp
        from Paul Eggert.
        (syntax-check-rules): Add it.

        * src/tail.c (main): Tweak Solaris OS version number in comment.
        * src/wc.c (wc): Likewise
        * tests/tail-2/fflush: Likewise.

        * src/tail.c: Add new undocumented option, --presume-input-pipe.
        (pipe_lines): Use memchr to skip lines, rather than an explicit loop.

2003-08-08  Paul Eggert  <eggert@twinsun.com>

        Use new gnulib 'extensions' module.
        * configure.ac: Invoke gl_USE_SYSTEM_EXTENSIONS instead of
        AC_GNU_SOURCE.

2003-08-08  Paul Eggert  <eggert@twinsun.com>

        * tests/du/basic: Ensure that a/b/F has at least 65 bytes too.

2003-08-09  Jim Meyering  <jim@meyering.net>

        * tests/misc/split-fail: Reflect that `split -a 0' is now accepted.
        For tests of obsolete behavior, don't presume that unsetting
        _POSIX2_VERSION is equivalent to _POSIX2_VERSION=199209.

2003-08-07  Paul Eggert  <eggert@twinsun.com>

        * doc/coreutils.texi (split invocation):
        Add -d or --numeric-suffixes option to 'split'.
        From a suggestion by Jesse Kornblum.
        * src/split.c (suffix_alphabet): New var.
        (longopts, usage, next_file_name, main): Support -d.
        (next_file_name, main): Allow -a0, as POSIX requires.
        (next_file_name): Don't assume ASCII-like encoding;
        'a' through 'z' are not contiguous in EBCDIC.

2003-08-05  Paul Eggert  <eggert@twinsun.com>

        Merge getline from gnulib.
        * lib/getline.h, lib/getline.c, m4/getline.m4: Merge from gnulib.
        * lib/getndelim2.h, lib/getndelim2.c, m4/getndelim2.m4, m4/ssize_t.m4:
        New files, from gnulib.
        * lib/getdelim2.c, lib/getdelim2.h: Remove.
        * lib/Makefile.am (libfetish_a_SOURCES): Change getdelim2.c and
        getdelim2.h to getndelim2.c and getndelim2.h.
        * m4/jm-macros.m4 (jm_MACROS): Use gl_GETNDELIM2 rather than
        checking for getdelim.
        (jm_CHECK_ALL_TYPES): Use gt_TYPE_SSIZE_T for ssize_t rather
        than rolling our own.
        * src/cut.c: Include getndelim2.h rather than getdelim2.h.
        (cut_fields): Invoke getndelim2 rather than getdelim2.

2003-08-04  Jim Meyering  <jim@meyering.net>

        * src/sort.c (main): Use unsigned int instead of int for `nsigs'
        and for the indices to iterate through nsigs.

2003-08-02  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c: Minor code cleanups, mostly to use more accurate
        types and to remove unnecessary casts.
        (min, max): Remove.  All uses changed to MIN and MAX.
        (hard_lc_collate, hard_LC_TIME, struct buffer.eof, struct
        keyfield.skipsblanks, struct keyfield.skipeblanks, struct
        keyfield.numeric, struct keyfield.general_numeric, struct
        keyfield.month, struct keyfield.reverse, reverse, unique,
        have_read_stdin): Now bool, not int.  All uses changed.
        (eolchar): Now char, not int.
        (struct keyfield.ignore): Now bool const *, not int *.
        (struct keyfield.translate): Now char const *, not char *.
        (struct month.name): Likewise.
        (blanks, nonprinting, nondictionary): Now bool[], not int[].
        (cleanup, inittables, keycompare, check, mergefps, first_same_file,
        check, sort, main): Use const * pointers when possible.
        (month_cmp): Rewrite to avoid casts.
        (inittables): Initialize tables unconditionally, to avoid branches.
        (fillbuf): Return bool, not int.  All uses changed.
        (fillbuf, keycompare, new_key, main):
        Use SIZE_MAX rather than (size_t) -1.
        (trailing_blanks): Renamed from trim_trailing_blanks.
        Return the number of blanks to trim.  All uses changed.
        (getmonth): Use trailing_blanks rather than open code.
        (keycompare): Do not cast char * to unsigned char *; not needed.
        CMP_WITH_IGNORE converts args to UCHAR, so no need to convert it
        ourselves.
        (compare, main): Use | rather than || to avoid jumps.
        Replace "diff = NONZERO (alen)" with "diff = 1", since alen must
        be nonzero there.
        (check, first_same_file, sort, main):
        Use bool instead of int local vars when possible.
        (check): Merge the old 'checkfp' and 'check' into a single function,
        that returns a boolean (true if the file was ordered).
        All uses changed.
        (main): Use int instead of unsigned for iterating through nsigs.
        Rename local var "posix_pedantic" to "posixly_correct".

2003-08-02  Jim Meyering  <jim@meyering.net>

        * src/nice.c [!NICE_PRIORITY]: Include <time.h> before <sys/resource.h>
        to avoid compilation error on Ultrix. Reported by Christian Krackowizer.

        * src/cut.c (cut_fields): Don't read again after encountering an
        initial EOF.  E.g., `cut -f2' would do so.
        * tests/misc/tty-eof: Add a test for the above fix.

        * src/sort.c (sortlines): Add description and references.
        From Paul Eggert.

        * tests/Makefile.am (TESTS_ENVIRONMENT): Set PATH so that
        the tests in help-version will use the just-built binaries.
        Reported by Christian Krackowizer.

2003-07-31  Paul Eggert  <eggert@twinsun.com>

        * NEWS: Add --rfc-2822 option to GNU date.
        * doc/coreutils.texi (Time directives, Options for date, Examples
        of date): Likewise.
        * src/date.c (long_options, usage, main): Likewise.
        * doc/getdate.texi (General date syntax): Likewise.
        * doc/coreutils.texi (Options for date): Fix a typo in format:
        it's now %d not %_d.  Add URLs.

2003-08-01  Jim Meyering  <jim@meyering.net>

        * tests/shred/remove: Ensure that $? is 0 for the final `exit 0'.
        Otherwise, with at least the /bin/sh from HPUX 10.20,
        the trap code would end up converting that to exit 1 and thus an
        unexpected test failure.  Reported by Christian Krackowizer.

2003-07-31  Paul Eggert  <eggert@twinsun.com>

        * src/ptx.c: Do not include bumpalloc.h.
        (WORD_TABLE): New member alloc.
        (ALLOC_NEW_WORD): Remove.
        (occurs_alloc): New var.
        (digest_word_file, find_occurs_in_text): Check for arithmetic
        overflow when computing table size.  Use xrealloc rather than
        bumpalloc primitives.

2003-07-29  Jim Meyering  <jim@meyering.net>

        * Version 5.0.90.

        * README: When running tests as root, suggest using
        sudo with NON_ROOT_USERNAME=$USER.

        * tests/Makefile.am (all_programs): Makefile is in ../src, not
        $(srcdir)/../src.

2003-07-28  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (GZIP_ENV): Try Debian/gzip's new --rsyncable option.

2003-07-28  Paul Eggert  <eggert@twinsun.com>

        * lib/stdbool.hin (_Bool): Make it signed char, instead of
        an enum type, so that it's guaranteed to promote to int.
        * src/sort.c (sortlines_temp): Undo previous change.

2003-07-28  Jim Meyering  <jim@meyering.net>

        * src/sort.c (sortlines_temp): Declare local `swap' to be `int', not
        `bool'.  Otherwise, at least one buggy compiler (alpha gcc-2.95.4)
        would cause lines[-1 - swap] (with swap = false) to evaluate to
        lines[4294967295].

2003-07-27  Jim Meyering  <jim@meyering.net>

        * tests/priv-check (my_uid): Use `!', not `^' in case pattern `[!0-9]',
        since /bin/sh of at least NetBSD 1.6 and OpenBSD 3.2 don't accept `^'.

        * src/remove.c (prompt) [! recursive]: Don't prompt about unwritable
        directories, as required by POSIX.   Reported by Karl Berry.
        * tests/rm/dir-no-w: New file.  Test for the above fix.
        * tests/rm/Makefile.am (TESTS): Add dir-no-w.

        * tests/mk-script: Emit `$xx', not its expansion.

2003-07-27  Paul Eggert  <eggert@twinsun.com>

        This change was inspired by a similar proposal by Stepan Kasal.
        * src/sort.c (mergelines, sortlines_temp): New functions.
        (sortlines): Use them, to reduce the number of times that
        we need to copy 'struct line' values.  This improved CPU
        performance by about 30% on one 18 MB test.
        (sort): Don't invoke sortlines unless we have 2 or more lines.

2003-07-26  Stepan Kasal  <kasal@ucw.cz>

        * src/sort.c (sort): Don't require two `struct line's per text line,
        the new sort algorithm requires just 1.5.

2003-07-27  Jim Meyering  <jim@meyering.net>

        * src/pathchk.c (validate_path): Use %lu, not %ld.
        From Paul Eggert.
        * src/cut.c (is_printable_field): Simplify bit arithmetic.
        From Paul Eggert.
        * src/ls.c (sort_files): Put `volatile' in the right place.
        From Paul Eggert.

2003-07-26  Jim Meyering  <jim@meyering.net>

        Use only one bit per field/offset in array, not one `int'.
        * src/cut.c (printable_field): Change type to `unsigned char'.
        (mark_printable_field, is_printable_field): New functions.
        Use them in place of all direct accesses of `printable_field'.

        * src/expand.c (parse_tabstops): Detect overflow properly.
        * src/cut.c (set_fields): Likewise.

        * src/rm.c: Include "dirname.h".
        (usage): Use base_name (program_name) in body of --help output.
        This lets me...
        * man/Makefile.am (.x.1): ...back out the kludge of 2003-07-22.
        Idea from Brendan O'Dea, who suggested using
        `program_name = basename (argv[0]);' everywhere --
        can't do that, but using base_name works just fine here.

        * src/Makefile.am (AM_INSTALLCHECK_STD_OPTIONS_EXEMPT): Exempt test.

2003-07-24  Paul Eggert  <eggert@twinsun.com>

        Fix some POSIX-compliance problems with 'test'.  This makes
        'test' more compatible with Bash.

        * NEWS, doc/coreutils.texi: Document the following.
        * src/test.c: Include exitfail.h.
        (TEST_FAILURE): New constant, used for exit status if 'test' fails.
        (test-syntax_error): Use it.
        (binary_operator): Now takes bool arg specifying whether left operand
        is -l ARG, so that caller determines this rather than us.
        All uses changed.
        (term): Use posixtest to evaluate parenthesized subexpressions.
        (unary_operator, one_argument): Remove support for -t without operand.
        (one_argument): Take argument from argv[pos].
        (one_argument, two_arguments, three_arguments): Advance pos.
        All callers changed.
        (three_arguments): Look for binary ops before "!".  Then look
        for parenthesized one_argument expressions, instead of trusting
        expr () to do the right thing.
        (posixtest): Now takes number of args.  All callers changed.
        Treat "( A B )" like "A B".
        (main): Set exit_failure to TEST_FAILURE.  Don't depend on
        POSIXLY_CORRECT, as we now conform to POSIX by default.
        (main) [!LBRACKET]: Do not recognize "--help" or "--verbose" unless.
        * tests/test/Test.pm (test_vector): Add several tests to check
        the above.  Syntax errors now exit with status 2, not 1.
        * man/Makefile.am (mapped_name): Use `../src/[' binary to create test.1.

2003-07-26  Jim Meyering  <jim@meyering.net>

        * tests/help-version: Adjust for above change in test behavior:
        `[' exits with 2, not 1, and test doesn't accept --help or --version.

        * Makefile.maint (ME): Don't use trick suggested in Make manual.
        It doesn't work for make-3.79.1.  Reported by Christian Krackowizer.

        * Makefile.maint (sc_system_h_headers): Another syntax check.
        (syntax-check-rules): Add it to the list.

        * src/pathchk.c (validate_path): Cast strlen value to `unsigned long'
        so it matches `%ld' format even on 32-bit systems.

        * src/fmt.c (flush_paragraph): Cast field width to `int' to
        avoid warning on 64-bit systems.

        * src/ls.c (sort_files): Make `func' volatile, so it can't be
        clobbered by a `longjmp' into this function.

2003-07-25  Jim Meyering  <jim@meyering.net>

        * src/pathchk.c (validate_path): Use %ld format (not %d) for size_t
        value.

        * tests/misc/split-fail: Disable the --line-bytes=$_4gb test,
        because it'd evoke spurious failure on 64-bit systems.

2003-07-24  Jim Meyering  <jim@meyering.net>

        * src/dd.c (usage): Document the fact that SIGUSR1 makes dd
        output its current record counts.  Reported by Jurriaan.

        * tests/wc/Test.pm (test_vector): Disable the `PIPE' tests when running
        `wc' with no options.  This goes along with the change of 2003-07-20.

2003-07-23  Jim Meyering  <jim@meyering.net>

        Don't include headers already included by system.h:

        * uniq.c, uptime.c, users.c, wc.c, who.c, whoami.c, yes.c:
        Don't include closeout.h.

        * tests/rm/fail-2eperm: Add a check for whether $NON_ROOT_USERNAME
        can access the required version of rm.
        * tests/rm/Makefile.am (TESTS_ENVIRONMENT): Define PACKAGE_VERSION.

        * tests/cut/Test.pm (out-delim3a): New test.

        * man/help2man: Update to version 1.33.

        * src/expand.c (parse_tabstops): Detect overflow in tabstop sizes.

        * src/dircolors.c: Include xstrndup.h.
        (xstrndup): Remove function, now that it's been factored out into
        it's own file.

2003-07-22  Paul Eggert  <eggert@twinsun.com>

        * src/wc.c (wc): Fix typo in computation of file from file_x,
        which caused the former to be used uninitialized if file_x was
        nonzero.

2003-07-22  Jim Meyering  <jim@meyering.net>

        * src/cut.c (set_fields): Use xcalloc in place of xmalloc+memset.

        * man/Makefile.am (.x.1): Substitute 's,$t/$*,$*,' on output of
        help2man, to avoid having `rm.td/rm' appear in rm.1.  Reported by
        Thomas Luzat.  See http://bugs.debian.org/202413 for details.

        * src/cut.c (main) [lint]: Initialize spec_list_string to avoid warning.

        * src/hostid.c: Don't include <unistd.h>.  system.h already does that.

        * src/cut.c (set_fields): Mark all selected indices before trying to
        determine range endpoints.
        * tests/cut/Test.pm: New test for the above fix.

        Begin to address this comment: What if someone wants to
        extract the 1,000,000-th field of some huge input file?
        The first step is to rearrange things so that the values
        in the printable_field array are all 0/1 rather than 0/1/2.
        * src/cut.c (RANGE_START_SENTINEL): Remove.
        Store range-start indices in a hash table, rather than
        overloading the `printable_field' array.
        (range_start_ht): New global.
        (hash_int, hash_compare_ints, is_range_start_index): New functions.
        (print_kth): Use is_range_start_index; don't test printable_field.
        (set_fields): Detect overflow.
        (set_fields): Insert each range-start index into range_start_ht.
        (main): Call set_fields only once, and only after
        output_delimiter_specified and (if required) range_start_ht have
        been defined.

2003-07-20  Paul Eggert  <eggert@twinsun.com>

        * src/wc.c (get_input_fstatus): Fix typo: `stat' was being
        invoked with a null pointer when there were no file arguments.

2003-07-20  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (sc_changelog): Add another nit-picky check.

        * src/wc.c (write_counts): Add a comment.
        (wc): Rename `file' parameter.
        Set new local, `file', to be the file name, or (when it's NULL)
        _("standard output") so that all uses of `file' use the proper value.
        Use STREQ, not strcmp.

2003-07-20  Paul Eggert  <eggert@twinsun.com>

        wc count field widths now are heuristically adjusted depending
        on the input size, if known.  If only one count is printed, it
        is guaranteed to be printed without leading spaces.

        Previously, wc did not align the count fields if
        POSIXLY_CORRECT was set, but POSIX did not actually require
        this undesirable behavior, so it has been removed.

        * NEWS: Document this.
        * doc/coreutils.texi (wc invocation): Likewise.

        * src/wc.c (number_width): New var.
        (posixly_correct): Remove.
        (struct fstatus): New struct.
        (write_counts): Output fields of width number_width.
        Do not worry about POSIXLY_CORRECT.
        Use null file, not empty-string file, to denote stdin,
        since "" is a valid file name on some hosts.
        (wc, wc_file): New arg fstatus.  Use it to avoid invoking fstat
        if possible.
        (wc):  Avoid problems if end_pos - current_pos overflows.
        Do not print odd message if stdin has a read error.
        (get_input_fstatus, compute_number_width): New functions.
        (main): Use them to implement the new behavior.
        Ignore POSIXLY_CORRECT.

        * tests/wc/Test.pm: Adjust to the new output widths.

2003-07-19  Jim Meyering  <jim@meyering.net>

        * tests/rm/fail-eperm: Don't create temporary directory --
        we don't use it.

        * tests/shred/remove: Don't open-code test for UID != 0.
        Use priv-check's require-non-root instead.
        Update to use newer framework.

        * tests/help-version (expected_failure_status_expr): Record that
        expr exits with status of 3 for e.g., a write error.

        * tests/priv-check: Use `id -u' to see if we're running as root,
        rather than trying go write to an write-protected file.
        When running as root, ensure $NON_ROOT_USERNAME is valid.
        When running as root with `require-non-root', ensure that `.'
        is writable by $NON_ROOT_USERNAME, then reinvoke $0 set-user-ID
        to $NON_ROOT_USERNAME.  If `.' is not writable, then skip the test.

        * src/printenv.c: Include "exitfail.h".
        (main): Set exit_failure rather than calling close_stdout_set_status.
        * src/date.c: Likewise.
        * src/sort.c: Likewise.
        * src/tty.c: Likewise.

2003-07-18  Jim Meyering  <jim@meyering.net>

        * tests/touch/not-owner: Update to use newer framework.

        * tests/rm/fail-eperm: Use $srcdir/../priv-check, create a temporary
        directory, and remove Perl-coded `you may not run as root' test.
        * tests/cp/fail-perm: Use $srcdir/../priv-check, rather than
        hard-coding something not quite equivalent.
        Paul Jarc reported the inconsistent diagnostics.

        * src/sort.c (main): Use close_stdout via atexit.
        Now `sort --version' and `sort --help' fail, as they should
        when their output is redirected to /dev/full.

        * src/su.c (usage): Don't call close_stdout here.
        (main): Use close_stdout via atexit.
        Now `su --version > /dev/full' fails, as it should.
        Somehow, the change of 2000-05-07 that purports to fix this
        was not checked in.

        * tests/help-version (--help/--version vs. /dev/full): Special-case
        `[' to protect it from expected_failure_status-`eval'.

        * src/uniq.c (writeline): Use a SPACE, not a TAB between the
        count and the corresponding line, as required by POSIX.
        Reported by Clement Wang.
        * tests/uniq/Test.pm (101, 102): Update tests of -c accordingly.

        * tests/expr/basic: Add tests for when exit status is 2.

        * src/nohup.c (NOHUP_FOUND_BUT_CANNOT_INVOKE, NOHUP_FAILURE):
        Use an anonymous `enum', rather than #define.

2003-07-17  Paul Eggert  <eggert@twinsun.com>

        * src/expr.c: Include "exitfail.h", "quotearg.h".
        (EXPR_INVALID, EXPR_ERROR): New constants.
        (nomoreargs, null, toarith, nextarg): Return bool, not int.
        (syntax_error): New function, exiting with status 2.  Use it
        insteading of printing "syntax error" ourselves.
        (main): Initialize exit_failure to EXPR_ERROR.
        Exit with EXPR_INVALID on syntax error (too few arguments).
        (nextarg): Use strcmp, not strcoll; strcoll might return
        an undesirable 0, or might fail.
        (docolon, eval4, eval3): Exit with status 3 on invalid argument type
        or other such error.
        (eval2): Report an error if strcoll fails in a string comparison.
        * src/sort.c: Include "exitfail.h".
        (main): Set exit_failure, not xalloc_exit_failure and
        xmemcoll_exit_failure.
        * tests/expr/basic: Invalid value exits with status 3, not 2.

2003-07-16  Jim Meyering  <jim@meyering.net>

        * configure.ac (AC_INIT): Use 5.0.90 as the version, rather than 5.0.2,
        per GNU maintainer guidelines.  The next non-beta release will be 5.1.

        This script would have caught at least two recent bugs:
        those in [ and kill.
        * tests/help-version: Revive this script.
        It wasn't doing anything useful, since $all_programs wasn't being
        defined by the invoking Makefile.am.
        Reflect that nohup is no longer a script, so don't exclude it.
        Add framework to handle the programs added since it was last run:
        kill, stat, unlink, [, link, readlink.
        Fix path-related problems deriving from the move of this script
        from src/ to its present location.
        * tests/Makefile.am (all_programs): Define.
        (TESTS_ENVIRONMENT): Use it.

        * src/kill.c (main): Fix bug introduced on 2003-05-10 (for 5.0.1)
        whereby kill would always attempt to operate on argv[0] and fail.

        * src/test.c (integer_expected_error): Improve diagnostic -- now,
        it also matches the one from bash's builtin test.
        (binary_operator): Add \n at end of diagnostic.

        * tests/rm/fail-2eperm: Remove setuidgid-related code.  Move it to ...
        * tests/priv-check: Move setuidgid-related and
        NON_ROOT_USERNAME-checking code to this file.

        * README: Update section on testing as `root'.
        Suggestion from Paul Jarc.

        * src/test.c (AUTHORS): Replace 3-letter usernames with the actual
        names of authors that I just found in bash's builtins/test.def.

        Running `[' with no arguments would evoke a segfault.
        * src/test.c (main) [LBRACKET]: Move initialization of argv to
        precede potential use via test_syntax_error.

        * src/Makefile.am (AM_CPPFLAGS): Rename from `INCLUDES', to avoid
        warning from automake -Wall.

2003-07-15  Jim Meyering  <jim@meyering.net>

        * Version 5.0.1.

        * Makefile.maint (%.asc): Remove target first, so gpg doesn't
        prompt us about it.

        * announce-gen (print_changelog_deltas): Relax tests for matching
        version-number line in NEWS.
        Change the .sig suffix to .asc here, too.

2003-07-14  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (%.asc): Renamed from %.sig.
        Generate and use ascii-armored signatures.
        Use gpg's -o option.

2003-07-13  Jim Meyering  <jim@meyering.net>

        * src/nohup.c (NOHUP_FAILURE, NOHUP_FOUND_BUT_CANNOT_INVOKE): Define.
        (main): Use them.

        * Makefile.maint (syntax-check): Move each individual check into
        its own target.
        (syntax-check-rules): This is the list of syntax-check targets.
        (sc_unmarked_diagnostics, sc_cast_of_argument_to_free):
        (sc_cast_of_x_alloc_return_value, sc_space_tab):
        (sc_error_exit_success, sc_xalloc_h_in_src):  New targets.

2003-07-12  Jim Meyering  <jim@meyering.net>

        * configure.ac: Remove uses of OPTIONAL_BIN_ZCRIPTS and last
        traces of the nohup script.

        * src/Makefile.am (bin_SCRIPTS): Remove use of just-removed
        $(OPTIONAL_BIN_ZCRIPTS).

        * src/Makefile.am (localedir.h): Put the `2>&1' after the redirect
        target, not before the `>'.

        * src/remove.c (remove_dir): Give a diagnostic upon failed save_cwd,
        now that that function no longer calls `error'.

        * src/df.c (find_mount_point): Emit a diagnostic for each
        failed syscall, rather than relying on caller to do that.
        The caller couldn't do a good job, anyhow -- too many different
        ways to fail (each with a different referent).
        Give a diagnostic upon failed save_cwd, now that that function
        no longer calls `error'.
        (show_point): Don't diagnose find_mount_point's errors, now that
        it handles them itself.

        * src/df.c (find_mount_point): Don't let free clobber errno upon
        failed chdir.

        * src/sys2.h: Remove alloca-related block.
        * src/system.h: Include <alloca.h> here, instead.

        It appears that the `#pragma alloca' included via "system.h" is
        adequate, since join.c uses alloca, yet lacked an in-file #pragma.
        * src/copy.c, src/cp.c, src/df.c, src/install.c, src/ln.c:
        * src/ls.c, src/mv.c, src/remove.c: Remove `#pragma alloca'.

        * src/chown-core.c (change_file_owner): Do not restore any special
        permission bits (e.g., set-user-ID, set-group-ID) that are reset
        by chown(2) on some systems.  Suggestion and insistence :-) from
        Michael Stone.

        * tests/input-tty: Also check `test -t 1'.
        This is necessary on linux-2.4.21.  Otherwise, the stty/basic-1
        test would block when run in the background.

2003-07-11  Jim Meyering  <jim@meyering.net>

        * tests/sample-test: Also fail if cat-to-create-expected-output
        fails.  Otherwise, if both `exp' and `out' were to end up empty
        because of e.g., a full disk, they would mistakenly compare equal.

        * src/nohup.c: New file.  Rewrite of nohup.sh in C.
        This solves a portability problem: on at least Solaris systems,
        when nohup.sh used the vendor /bin/sh, it would exit with status
        of `1' rather than the required 126 or 127 upon failure to exec
        the specified program.

        * src/Makefile.am (EXTRA_SCRIPTS): Remove definition.
        (bin_PROGRAMS): Add nohup.
        (EXTRA_DIST): Remove nohup.sh.
        (all_programs): Remove use of $(EXTRA_SCRIPTS).
        * src/nohup.sh: Remove file.
        * man/Makefile.am (nohup.1): Depend on nohup.c, rather than nohup.sh.

        * tests/misc/nohup: Tests for the above.
        * tests/misc/Makefile.am (TESTS): Add nohup.

        * src/head.c (diagnose_copy_fd_failure): New function, renamed from
        the macro, COPY_FD_DIAGNOSE.
        (diagnose_copy_fd_failure): Enclose diagnostic in _(...).
        (head_file): Likewise.

        * src/date.c: Include "quote.h".
        (batch_convert): Use the quote function rather than using literal `...'
        in a diagnostic.

        * src/setuidgid.c (main): Enclose diagnostic in _(...).
        * src/fmt.c (main): Likewise.
        * src/mknod.c (main): Likewise.
        * src/tac.c (tac_seekable): Likewise.
        * src/yes.c (main): Likewise.
        * src/od.c (main): Likewise.
        * src/install.c (change_attributes): Likewise.

2003-07-10  Jim Meyering  <jim@meyering.net>

        * src/head.c (usage): Use 1024*1024 in place of 1048576.
        * src/tail.c (usage): Likewise.

        * tests/rm/fail-2eperm: Now that we have setuidgid, use it in
        place of the kludge in this test.  Suggestion from Paul Jarc.

        * src/Makefile.am (noinst_PROGRAMS): Define to setuidgid.
        * src/setuidgid.c: New program, solely for testing (not installed).

        * src/chown-core.c (change_file_owner): Don't leak file descriptors
        when dereferencing symlinks.

2003-07-09  Jim Meyering  <jim@meyering.net>

        * tests/du/slash: New file/test for today's lib/ftw.c fix.
        * tests/du/Makefile.am (TESTS): Add slash

        * src/tail.c (xlseek): Avoid warning about ``return without value
        from function returning non-void''.

2003-07-08  Jim Meyering  <jim@meyering.net>

        * man/help2man: Update to version 1.29.

        * man/help2man: Add END handler to close STDOUT and check for errors.

2003-06-30  Paul Eggert  <eggert@twinsun.com>

        Add support for a "[" that conforms to the GNU coding standards,
        i.e., that does not depend on its name.
        * src/lbracket.c: New file.
        * README: Add "[".
        * man/Makefile.am (programs): Ignore "[", since it doesn't have
        a separate man page.
        * src/Makefile.am (bin_PROGRAMS): Add "[".
        (__SOURCES): New var.
        * src/test.c (LBRACKET): Define to 0 if not defined.
        (main): Use LBRACKET rather than argv[0].

        * src/test.c (one_argument): Do not check for -t if POSIXLY_CORRECT.
        Reported by Paul Jarc and Dan Jacobson.

        * src/test.c (main): Do not recognize --help or --version if
        POSIXLY_CORRECT, when invoked as "test".  Handle "[ ]" correctly.
        Do not bother testing that margv[margc] is non-null.

2003-07-04  Jim Meyering  <jim@meyering.net>

        * src/who.c (print_line): Rewrite to use asprintf, in order to be
        able to avoid emitting trailing spaces.  Reported by Dan Jacobson.

        * tests/misc/head-elide-tail: Add tests of head's new --lines=-N
        option, and perform the +1600 invocations of head IFF the envvar
        RUN_EXPENSIVE_TESTS is set.

2003-07-03  Jim Meyering  <jim@meyering.net>

        * src/cp.c (do_copy): Give a better diagnostic when failing due
        to nonexistent destination directory.  Reported by Dmitry Rutsky.
        See http://bugs.debian.org/199730 for details.

2003-06-27  Jim Meyering  <jim@meyering.net>

        split's --verbose option did nothing [broken in 4.5.10 and 5.0]
        * src/split.c (longopts): Use `1', not `0' as the value for
        for &verbose.  Reported by Keith Thompson.

        Test for the above fix.
        * tests/misc/split-a: Also use --verbose and compare stderr
        output with what we'd expect.

2003-06-20  Jim Meyering  <jim@meyering.net>

        * src/copy.c (copy_internal) [HAVE_STRUCT_STAT_ST_AUTHOR]:
        Use `error_t' (rather than int) as type for local `err'.
        From Alfred M. Szmidt.

2003-06-19  Marcus Brinkmann  <marcus@gnu.org>

        * src/copy.c (copy_internal) [HAVE_STRUCT_STAT_ST_AUTHOR]:
        Fix author preservation code.

2003-06-19  Jim Meyering  <jim@meyering.net>

        * src/ln.c (ENABLE_HARD_LINK_TO_SYMLINK_WARNING): Define to 0.
        (do_link): Don't warn about hard link to symlink.

2003-06-18  Jim Meyering  <jim@meyering.net>

        * src/cut.c: Include "getdelim2.h", not "getstr.h".
        Reflect renaming: getstr -> getdelim2.

        * src/comm.c, src/join.c, src/nl.c, src/uniq.c: Reflect renaming:
        readline -> readlinebuffer.

2003-06-09  John David Anglin  <dave.anglin@nrc-cnrc.gc.ca>

        * src/readlink.c: Include <sys/types.h> before system.h (because
        the latter includes <sys/stat.h>).  Required on Ultrix 4.3.

2003-06-17  Jim Meyering  <jim@meyering.net>

        * src/system.h (initialize_main): Define.
        Use it in every `main'.  Applied via this:
        p='initialize_main (&argc, &argv);'
        perl -ni -e '/program_name.=.argv.0/ and print "  '"$p"'\n"; print' \
          $(grep -l program_name.=.argv.0 *.c)
        test.c uses margc/margv, so I made the change manually for that file.
        Based on a patch from Bernard Giroud.

2003-06-09  John David Anglin  <dave.anglin@nrc-cnrc.gc.ca>

        Fix for build failure on Ultrix 4.3.
        * src/stat.c: Include sys/statvfs.h in preference to sys/vfs.h.
        Include sys/param.h and sys/mount.h on ultrix.

2003-06-16  Jim Meyering  <jim@meyering.net>

        * src/touch.c (O_NDELAY, O_NONBLOCK, O_NOCTTY, EISDIR): Remove
        definitions.
        * src/system.h (O_NDELAY, O_NONBLOCK, O_NOCTTY, EISDIR): Define
        them here instead, but with one change: define EISDIR to -1, not 0.

        * src/cat.c (cat): Remove `#ifndef ENOSYS', now that it's
        guaranteed to be defined.
        * src/system.h (ENOSYS, ENOTSUP): Define to -1 if not defined.

        * README: Mention the CVS repository.
        Encourage addition of test cases.

2003-06-12  Jim Meyering  <jim@meyering.net>

        * src/touch.c (touch): Call close only if necessary.
        From Bruno Haible.

        * src/wc.c (usage): Correct wording: wc prints counts in the order
        `newline, word, byte'.  Reported by Keith M. Briggs.
        * man/wc.x: Fix it here, too.  And change `lines' to `newlines'.

2003-06-10  Jim Meyering  <jim@meyering.net>

        * tests/date/Test.pm: Add a test for the new format, e.g., May-23-2003.

2003-06-07  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (syntax-check): Add commented-out (over-aggressive)
        rule.

2003-06-06  Jim Meyering  <jim@meyering.net>

        * src/extract-magic (main): Avoid newer 3-arg form of open,
        so this script works also with e.g., perl5.005_03.
        Patch by John David Anglin.

2003-06-04  Paul Eggert  <eggert@twinsun.com>

        * src/system.h: Include <stdbool.h> unconditionally.

2003-06-04  Jim Meyering  <jim@meyering.net>

        * man/Makefile.am (check-programs-vs-x): Rename target
        from check-programs-vs-1.  Adjust rule to check for the
        primary (.x) file, not the generated one (.1).

2003-06-03  Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>

        * man/kill.x: New file.
        * man/Makefile.am (dist_man_MANS): Add kill.1.
        (kill.1): New rule.

2003-06-04  Jim Meyering  <jim@meyering.net>

        Ensure that the .x file for a new program is never forgotten again.
        * man/Makefile.am (programs): Define.
        (check-programs-vs-1): New phony target.
        (check-local): Depend on it.

2003-06-03  Jim Meyering  <jim@meyering.net>

        Avoid unnecessary copying of environment.
        * src/env.c (main): Rather than clearing the environment and --
        unless told to ignore environment -- copying all settings from
        the saved, original environment, clear the environment only when
        that is requested.  Suggested by Jens Elkner.

2003-06-02  Jim Meyering  <jim@meyering.net>

        * src/system.h: Always include <string.h>, since we assume C89.
        Include <limits.h> without checking for HAVE_LIMITS_H.

        * src/test.c [!TEST_STANDALONE]: Remove #if-0'd block.
        (STREQ, S_IXUGO): Remove redundant (in system.h) definitions.

2003-06-01  Jim Meyering  <jim@meyering.net>

        Avoid a race condition in `tail -f' described by Ken Raeburn in
        http://mail.gnu.org/archive/html/bug-textutils/2003-05/msg00007.html
        * src/tail.c (file_lines): Add new parameter, *read_pos, and set it.
        (pipe_lines, pipe_bytes, start_bytes, start_lines): Likewise.
        (tail_bytes, tail_lines, tail): Likewise.
        (tail_file): Use the new `read_pos' value as the size,
        rather than stats.st_size from the fstat call.

2003-05-28  Jim Meyering  <jim@meyering.net>

        * src/extract-magic: Allow expansion of `$file' in the here-
        document corresponding to the comment at the top of fs.h.

2003-05-26  Jim Meyering  <jim@meyering.net>

        * src/stat.c: Fix portability problem on FreeBSD5.0: don't include
        <sys/statvfs.h> on systems without HAVE_STRUCT_STATVFS_F_BASETYPE.
        Use #if/#elif/... cascade so we get only one set of include files.
        Reported by Nelson Beebe.

2003-05-24  Jim Meyering  <jim@meyering.net>

        * src/md5sum.c (split_3): Accept the BSD format only when in MD5 mode.
        * tests/sha1sum/basic-1: Make sure `sha1sum --check' doesn't
        accept the BSD format.

2003-03-28  Joe Orton  <jorton@redhat.com>

        * src/md5sum.c (bsd_split_3): New function.
        (split_3): Detect checksums from BSD 'md5' command and handle them
        using bsd_split_3.

        * tests/md5sum/basic-1: New tests for --check exit status, and for
        BSD-style checksum files.

2003-05-21  Jim Meyering  <jim@meyering.net>

        * src/head.c (elide_tail_lines_pipe): Fix a thinko.
        This sort of thing is why it'd be *Really Good* to factor
        out the common code used here and in tail.c.

2003-05-14  Jim Meyering  <jim@meyering.net>

        * src/head.c (usage): Document new feature: --bytes=-N and --lines=-N.

        * tests/du/slink: Skip this test if `.' is on an XFS file system.

        * tests/du/fd-leak: New file.  Test for the bug in du that
        was fixed by the 2003-05-12 change to lib/ftw.c.
        * tests/du/Makefile.am (TESTS): Add fd-leak.

        * src/head.c (AUTHORS): Enclose string in N_(...), now that it
        includes a translatable word, `and'.

        * src/dd.c (usage): Don't use `,' as the thousands separator
        in e.g. 1,000,000 and 1,048,576.  Instead, do this:
        `SIZE may be ..., MB 1000*1000, M 1024*1024 and so on...'
        * src/df.c (usage): Likewise.
        * src/du.c (usage): Likewise.
        * src/ls.c (usage): Likewise.

        * Makefile.maint (syntax-check): Add another check.

2003-05-13  Paul Eggert  <eggert@twinsun.com>

        Fix uniq to conform to POSIX, which requires that "uniq -d -u"
        must output nothing.  Problem reported by Josh Hyman.

        * src/uniq.c (enum output_mode, mode): Remove, replacing with:
        (output_unique, output_first_repeated, output_later_repeated):
        New vars.  All uses of "mode" changed to use these variables,
        which are not mutually exclusive as "mode" was.
        (writeline): New arg "match", used to control whether to
        obey output_first_repeated or output_later_repeated.
        All callers changed.
        (check_file, main): Adjust to above changes.

        * tests/uniq/Test.pm: Test that 'uniq -d -u' outputs nothing.

2003-05-14  Jim Meyering  <jim@meyering.net>

        * tests/rm/rm3: Use tr's \n notation rather than \012.
        This package can afford to do that, since its tests are guaranteed use
        GNU tr, which has accepted the more modern notation for 10 years.
        * tests/rm/rm5: Likewise.
        * tests/cp/same-file: Likewise.
        * tests/stty/row-col-1: Likewise.
        * tests/stty/basic-1: Likewise.

2003-05-13  Jim Meyering  <jim@meyering.net>

        * src/copy.c (struct F_triple) [name]: Remove const attribute.
        (triple_free): Don't apply cast to argument of free.
        (seen_file): Add cast here instead.

        * src/cp-hash.c (struct Src_to_dest) [name]: Remove const attribute.
        (src_to_dest_free): Don't apply cast to argument of free.

        * src/join.c (delseq, freeline): Likewise.
        * src/expr.c (OLD): Likewise.
        * src/sort.c (sort): Likewise.
        * src/head.c (elide_tail_lines_pipe): Likewise.

        * src/tail.c: Include "quote.h".
        Use quote in diagnostics.  Change many error format strings
        from just `%s' to e.g., `error reading %s'.
        (pipe_lines): Change type of parameter, n_lines, to uintmax_t.
        Rewrite newline-counting loop to use memchr.

        * src/head.c (elide_tail_lines_pipe): Use `if', not assert.
        Now that assert is no longer used, don't include <assert.h>.

2003-05-12  Jim Meyering  <jim@meyering.net>

        * src/head.c: Include <assert.h>.
        (AUTHORS): Add my name.
        (elide_tail_lines_pipe): New function.

2003-05-10  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (syntax-check): Check for `error (EXIT_SUCCESS,'.

        * src/readlink.c (main): Set program_name before first use.
        Remove that (redundant) first use.
        Don't exit successfully just because --verbose was specified.
        Pass 0, not EXIT_SUCCESS, as first argument to error; when that
        parameter is 0, error does not exit.

        * src/uname.c (main): When failing due to too many arguments, also say
        that, rather than just "Try `uname --help' for more information.".
        * src/comm.c (main): Likewise, but for too few arguments.
        * src/logname.c: Include error.h.
        (main): Say why we're failing.

        * src/uniq.c (main): Don't segfault when argc < optind.

        * src/kill.c (send_signals): Don't check command line arguments here.
        (main): Check them here instead.  Handle argc < optind.

        * src/logname.c (main): Use error, rather than fprintf, for the sake
        of consistency.

        * src/rm.c (main): Don't overrun array bound if argc is 0.

2003-05-09  Jim Meyering  <jim@meyering.net>

        * src/sort.c (main): Don't overrun array bound if argc is 0.
        That would happen when invoked via: execl ("/usr/bin/sort", NULL);
        Reported by Wartan Hachaturow.

2003-05-07  Jim Meyering  <jim@meyering.net>

        Implement support so that `head --lines=-N' works on seekable files.
        * src/head.c (enum Copy_fd_status): Define.
        (COPY_FD_DIAGNOSE): New macro.
        (elide_tail_lines_seekable): New funtion.
        (elide_tail_lines_file): Call it here.

2003-05-06  Jim Meyering  <jim@meyering.net>

        * src/sys2.h (CHAR_BIT): Remove duplicate definition.

2003-05-04  Jim Meyering  <jim@meyering.net>

        * tests/head/Test.pm: Remove tests of --bytes=-N; using that framework
        caused the addition of thousands of small files to the tar archive.
        * tests/misc/head-elide-tail: New file.  Add them here instead.
        * tests/misc/Makefile.am (TESTS): Add head-elide-tail.

2003-05-04  Paul Eggert  <eggert@twinsun.com>

        * src/remove.c (HAVE_WORKING_READDIR): Define to 0 if not defined.
        (IF_READDIR_NEEDS_REWINDDIR): Remove.
        (remove_cwd_entries): Rewrite to avoid IF_READDIR_NEEDS_REWINDDIR,
        which was a bit weird because it couldn't be emulated by a function.

2003-05-03  Jim Meyering  <jim@meyering.net>

        Extend head to accept --lines=-N (--bytes=-N) and to print all
        but the N lines (bytes) at the end of the file.
        * src/head.c: Include full-write.h, full-read.h, inttostr.h, quote.h.
        Use quote() in diagnostics, rather than literal `' marks.
        (copy_fd, elide_tail_bytes_pipe, elide_tail_bytes_file):
        New functions.
        (elide_tail_lines_pipe, elide_tail_lines_file): New functions.
        (head_file): Reorganize so as to call head from only one place.
        (main): Likewise, for head_file.
        Handle new, undocumented option, --presume-input-pipe.
        Handle negative line and byte counts.
        * tests/head/Test.pm: Add lots of tests to exercise --bytes=-N.

        * tests/du/8gb: Skip test if the file system of `.' doesn't support
        sparse files -- otherwise it'd create a file of size 8GB.

2003-05-02  Jim Meyering  <jim@meyering.net>

        * src/fmt.c (usage): Don't mention obsolescent -WIDTH option.
        Instead explain about `-' and standard input.
        (main): Give a proper diagnostic for e.g., `fmt -c -72'.
        Reported by Keith Thompson.
        * tests/fmt/basic: Add test for the above fix.

        * src/fmt.c: Include "quote.h".
        Use quote() in diagnostics, rather than literal `' marks.
        (main): Exit nonzero when unable to open an input file.
        * tests/fmt/basic: Add test for the above fix.

        * src/fmt.c (main): Diagnose invalid suffix on obsolescent width
        specifications like `-72x'.
        * tests/fmt/basic: Add test for the above fix.

        Work around nasty readdir bug on Darwin6.5.
        * src/remove.c (IF_READDIR_NEEDS_REWINDDIR): Define.
        [! HAVE_WORKING_READDIR] (remove_cwd_entries): If readdir has just
        returned NULL and there has been at least one successful unlink or
        rmdir call since the opendir or previous rewinddir, then call
        rewinddir and reiterate the loop.

        Factor out common code.
        * src/remove.c (readdir_ignoring_dotdirs): New function.
        (is_empty_dir): Use it here.
        (remove_cwd_entries): Use it here.

2003-05-01  Jim Meyering  <jim@meyering.net>

        * tests/rm/r-3: Create 500 rather than just 300 files.
        There's a bug in Darwin6.5's readdir that shows up only with
        338 or more files.
        Fix a bug in this test: `cd $pwd' (not to `..'), now that $tmp
        has two components.

        * src/tail.c:
        Change type of n_units, n_bytes, n_lines to be `uintmax_t'.
        (dump_remainder): Move two declarations `down' into the scope
        where they are used.
        (xlseek): Return the resulting offset.
        (file_lines): Rename parameter, file_length, to end_pos.
        (pipe_lines): Don't coerce safe_read return value to `int'.
        Adapt tests accordingly.
        (pipe_bytes) [struct charbuffer] (nbytes): Change type from `int'
        to `unsigned int'.
        Change type of `total_bytes' from `int' to `size_t',
        since the former wouldn't always be wide enough.
        Don't coerce safe_read return value to `int',
        and adapt tests accordingly.
        Now that testing for a read error no longer involves
        using `tmp', handle that case *after* freeing `tmp'.
        (start_bytes): Clean up.
        (tail_bytes): Now that `n_bytes' may be larger than
        OFF_T_MAX, test for that condition and, if it's true, don't
        use lseek optimizations.
        (parse_options): Don't fail just because N_UNITS is larger than
        the maximum size of a file -- tail may be applied to an input
        stream (e.g., a pipe) with more data than that.

        * Makefile.maint (syntax-check): Rename from alloc-check.
        Also check for SPACE-TAB sequences.
        Also check for malloc/calloc/realloc casts.

2003-05-01  Jim Meyering  <jim@meyering.net>

        * src/tail.c (start_lines): Rewrite to use memchr.  Clean up.

2003-04-28  Jim Meyering  <jim@meyering.net>

        * tests/misc/tty-eof: Send two tokens, not just one, so we don't
        make the now-more-picky tsort fail.

2003-04-24  Jim Meyering  <jim@meyering.net>

        * src/tsort.c (tsort): Remove unnecessary test of have_read_stdin.
        (main): Minor syntactic clean-up.

        * src/tsort.c (tsort): Fail if the input contains an odd number of
        tokens.  Reported by junkio@cox.net.

        * tests/tsort/basic-1: Test for the above fix.

2003-04-21  Jim Meyering  <jim@meyering.net>

        * tests/misc/printf: Add tests for the printf fixes below.

        * Makefile.cfg (cvs_files): Add $(srcdir)/config/depcomp to the list.

2003-04-20  Paul Eggert  <eggert@twinsun.com>

        Fix printf POSIX compatibility bug reported by Ben Harris in
        <http://mail.gnu.org/archive/html/bug-coreutils/2003-04/msg00070.html>.
        * doc/coreutils.texi (printf invocation): It's \NNN in the format,
        \0NNN in the %b operand.
        * src/printf.c (usage): Likewise.
        (print_esc): New arg OCTAL0 to specify whether \0NNN or \NNN
        is desired.  All uses changed.  Behave like Bash printf if %b
        operand uses \NNN where the initial N is not 0.

2003-04-17  Jim Meyering  <jim@meyering.net>

        * src/stty.c: Remove uses of PROTOTYPE macro.

2003-04-15  Jim Meyering  <jim@meyering.net>

        * Makefile.maint: Remove (or replace-with-TAB(s) to retain alignment)
        each sequence of spaces before a TAB character.

2003-04-13  Jim Meyering  <jim@meyering.net>

        * src/remove.c (is_empty_dir): Don't closedir (NULL).

2003-04-12  Jim Meyering  <jim@meyering.net>

        Giving nl an invalid STYLE argument (in --header-numbering=STYLE (-h),
        --body-numbering=STYLE (-b), or --footer-numbering=STYLE (-f)) or
        FORMAT (--number-format=FORMAT (-n)) would not give a useful diagnostic.
        * src/nl.c (main): Fix those problems and remove literal quote marks
        (e.g., "`%s'") from format string; instead use "%s" in each format
        string and `quote (optarg)' as the corresponding argument.
        Also, diagnose all invalid command line options before failing.

        * src/nl.c (proc_text): Fix a bug that would make nl output extra
        newlines in some cases.  Details here: http://bugs.debian.org/177256.
        This bug was introduced on 2001-11-10 for textutils-2.0.17.
        * tests/misc/nl: Add test for the above-fixed bug.

        * tests/misc/readlink: New file.  Test the --canonicalize option.
        * tests/misc/Makefile.am (TESTS): Add readlink.

2003-04-11  Jim Meyering  <jim@meyering.net>

        Clean up.
        * src/chown.c, src/cp.c, src/dircolors.hin, src/du.c, src/ln.c:
        * src/mkfifo.c, src/ptx.c, src/spline.c, src/stty.c, src/tail.c:
        * src/test.c, src/unexpand.c: Remove (or replace-with-TAB(s) to
        retain alignment) each sequence of spaces before a TAB character.

        * src/ls.c: Include <stdlib.h> unconditionally.

        * Makefile.maint (xalloc-check): Rename from header-check.

        * src/yes.c: Include error.h after system.h, not before.

        Clean up.
        * src/copy.c, src/cp-hash.c, src/cp.c, src/csplit.c, src/cut.c:
        * src/date.c, src/df.c, src/du.c, src/expand.c, src/expr.c, src/id.c:

        * src/tr.c: * src/unexpand.c, src/users.c:
        Remove anachronistic casts of xmalloc, xrealloc, and xcalloc
        return values and of xrealloc's first argument.
        Fix the former with this:
        perl -pi -e 's/\([^(]*?\*\) *(x(m|c|re)alloc)\b/$1/'

2003-04-10  Jim Meyering  <jim@meyering.net>

        * src/stty.c (wrapf): Declare with format attribute.

        The S_MAGIC_... names shouldn't be maintained in two places (prior
        to this change, one would have to keep stat.c and fs.h in sync).
        This change makes it so those names and the corresponding
        hexadecimal constants all reside in stat.c.  fs.h is now generated.
        * src/Makefile.am (fs.h): New rule to generate fs.h from stat.c.
        (BUILT_SOURCES): Add fs.h, now that it's generated.
        (EXTRA_DIST): Add extract-magic.
        * src/extract-magic: New script to extract fs.h definitions from stat.c.
        * src/stat.c (human_fstype) [__linux__]: Append each hex constant from
        fs.h in a comment after the corresponding `case S_MAGIC_...:' statement.

        * tests/tail-2/big-4gb: Skip this test (don't fail) if creating a
        file with nominal length > 4GB fails.  Reported by Michael Deutschmann.

        * man/unexpand.x: Add `SEE ALSO' reference to expand.
        * man/expand.x: Add `SEE ALSO' reference to unexpand.
        Suggestion from Dan Jacobson.

2003-04-10  Maciej W. Rozycki  <macro@ds2.pg.gda.pl>

        * src/fs.h (S_MAGIC_DEVPTS): New magic for Linux's devpts.
        * src/stat.c (human_fstype): Handle Linux's devpts.

2003-04-09  Paul Eggert  <eggert@twinsun.com>

        * src/split.c (line_bytes_split): Arg is of type size_t, since
        that's all that is supported for now.
        (main): Check for overflow in obsolescent line count option.

2003-04-09  Jim Meyering  <jim@meyering.net>

        * tests/misc/split-fail: Add a new test for the above fix.

        * src/split.c (bytes_split): Use size_t temporary (rather than
        uintmax_t original) in remaining computations.  From Paul Eggert.

        Handle command line option arguments larger than 2^31.
        This allows e.g., splitting into files of size 2GB and larger,
        and running split --lines=N with N=2^31 or more.
        But for --line-bytes=N, the restriction that N <= SIZE_MAX
        remains (for now), due to the way it is implemented.

        * src/split.c: Include "inttostr.h".
        (bytes_split, lines_split, line_bytes_split, main):
        Use uintmax_t, not size_t, for file sizes.
        (main): Give a better diagnostic for option arguments == 0.
        Use umaxtostr to print file sizes.
        Reported by Luke Hassell.

2003-04-08  Jim Meyering  <jim@meyering.net>

        * src/rm.c (usage): Mention that --directory (-d) works only
        on some systems.  Suggestion from Samuel Tardieu.

        * tests/basename/basic: Run $PERL to see if it is available,
        rather than testing its value.
        * tests/sum/sysv, tests/tsort/basic-1, tests/unexpand/basic-1:
        * tests/basename/basic, tests/dd/skip-seek, tests/dircolors/simple:
        * tests/expr/basic, tests/factor/basic, tests/fmt/basic:
        * tests/ls-2/tests, tests/md5sum/basic-1, tests/md5sum/newline-1:
        * tests/misc/sort, tests/misc/tty-eof, tests/mv/i-1:
        * tests/rm/empty-name, tests/rm/fail-eperm, tests/rm/unreadable:
        * tests/seq/basic, tests/sha1sum/basic-1, tests/sha1sum/sample-vec:
        * tests/sum/basic-1, tests/seq/basic: Likewise.

        * tests/misc/Makefile.am (TESTS): Add split-fail.
        * tests/misc/split-fail: New file.

        * src/split.c: Rename local variables: nchars -> n_bytes.
        (lines_split): Rename local, nlines -> n_lines.
        (main): Rename local variable: s/accum/n_units/.
        (main): Use STDIN_FILENO, not literal `0'.

2003-04-07  Jim Meyering  <jim@meyering.net>

        * src/stat.c: Add #include directives for Ultrix 4.4.
        Based on a suggested change from Bert Deknuydt.

2003-04-06  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (makefile-check): New rule.
        (local-check): Add it.

2003-04-05  Jim Meyering  <jim@meyering.net>

        * Makefile.am (nearly all of them):
        Use $(VAR) rather than @VAR@, now that we can rely on automake to
        emit a definition for each substituted variable.
        * tests/Makefile.am.in: Likewise.

        * tests/rm/rm5: Add a comment explaining why this test fails when
        using Tru64's broken sed.
        * tests/rm/rm3: Likewise.

        Make `kill -t' output signal descriptions (not `?') on Tru64.
        * src/kill.c (sys_siglist): Also check for __sys_siglist.
        Patch by Tony Leneis.
        * configure.ac: Also check for declaration of __sys_siglist.
        Required for Tru64 4.0D, 4.0F, and 5.1.
        Reported by Tony Leneis.

2003-04-04  Jim Meyering  <jim@meyering.net>

        * src/Makefile.am (PERL): Remove unnecessary definition.

        Because of inappropriate (but POSIX-mandated) behavior of rename,
        `mv a b' would not remove `a' in some unusual cases.  Work around
        this by unlinking `a' when necessary.

        * src/copy.c (same_file_ok): Add an output parameter.
        Set it in the offending case.
        (copy_internal): When necessary, unlink SRC_PATH and inform caller.
        Reported by Ed Avis.
        * tests/mv/hard-4: New test for the above.
        * tests/mv/Makefile.am (TESTS): Add hard-4.

        Clean up rules for automatically generated sources:
        * src/Makefile.am (dircolors.h, wheel-size.h, wheel.h, false.c):
        Make each generated file be read-only.
        Add each file name to BUILT_SOURCES separately.
        (MAINTAINERCLEANFILES): Set to $(BUILT_SOURCES).

        Put LOCALEDIR macro definition in new file: localedir.h.
        * src/Makefile.am (DEFS): Remove definition.
        (localedir.h): New rule.
        (BUILT_SOURCES, DISTCLEANFILES): Add localedir.h.
        * src/system.h: Include "localedir.h".

2003-04-02  Jim Meyering  <jim@meyering.net>

        * Version 5.0.

        * tests/misc/Makefile.am (TESTS): Add false.

        * Makefile.maint (TMPDIR): Make sure it's defined.
        (my-distcheck): Build in $(TMPDIR), not `.'.

        * src/Makefile.am (false.c): Change all occurrences of
        `(EXIT_SUCCESS)' to `(EXIT_FAILURE)' so that false exits
        unsuccessfully also with --help.  Reported by Paul Jarc,
        * tests/misc/false: New test for the above.

2003-03-30  Jim Meyering  <jim@meyering.net>

        * NEWS: Note the location of older NEWS files.

        * src/remove.c (is_empty_dir): Don't let a failing closedir
        clobber errno.  Spotted by Arnold Robbins.

        * src/env.c: Fix typo in comment.  From Arnold Robbins.

2003-03-29  Jim Meyering  <jim@meyering.net>

        * Version 4.5.12.

        * README: Note to expect build problems for stat.c on Ultrix 4.3.
        Note that there are some harmless test failures when running
        `make check' as root on some systems.

2003-03-28  Jim Meyering  <jim@meyering.net>

        * tests/stty/row-col-1: Skip this test if stty can't get window size.
        This happens when connecting to sparc-solaris5.7 via ssh from within
        emacs.  Reported by Karl Berry.

        * tests/du/basic: Use seq, not `yes' to generate 4KB of data.
        Otherwise, on systems (DJGPP) that emulate pipes using files,
        this test would never complete, waiting for `yes' to terminate.
        * tests/du/slink: As above, use seq, not `yes' to generate link target.
        * tests/rm/hash: As above, use seq, not `yes' to generate dir name.
        Reported by Rich Dawe.

2003-03-27  Jim Meyering  <jim@meyering.net>

        * src/id.c: Remove Arnold Robbins' obsolete e-mail address
        from `written by...' comment, at his request.

2003-03-24  Paul Eggert  <eggert@twinsun.com>

        Fix buffer overrun problem reported by TAKAI Kousuke, along
        with some other POSIX incompatibilities.

        * src/printf.c (print_esc): Do not treat \x specially if
        POSIXLY_CORRECT.  Avoid buffer overrun if the format ends
        in backslash.  Treat incomplete escape sequences as strings
        of characters, as POSIX requires.
        (print_formatted): Allow multiple flags.  Avoid buffer overrun
        if the format is incomplete.

2003-03-24  Jim Meyering  <jim@meyering.net>

        * tests/misc/printf: Add tests for the above fixes and changes.

2003-03-26  Jim Meyering  <jim@meyering.net>

        * src/copy.h (struct cp_options): Add a comment.

2003-03-23  Jim Meyering  <jim@meyering.net>

        * README: Describe problem with 64-bit mode on HPUX 11.x,
        with patch for /usr/include/inttypes.h.
        * TODO: Plan to add an autoconf test to work around the bug.

2003-03-22  Jim Meyering  <jim@meyering.net>

        * src/stat.c: Don't include <sys/sysmacros.h>.
        That is already done via system.h.  Otherwise, the multiple
        inclusion would evoke redefinition warnings from Cray's /bin/cc,
        aka Cray Standard C Version 4.0.3  (057126) Mar 22 2003  22:02:28.
        (human_fstype): Factor some directives `up', out of this function.
        Cast away `const' to avoid error from Cray's /bin/cc.

2003-03-20  Jim Meyering  <jim@meyering.net>

        * announce-gen (print_changelog_deltas): Ensure that a newline
        precedes each row of `*'s.

2003-03-20  Jim Meyering  <jim@meyering.net>

        * Version 4.5.11.

        * src/seq.c (valid_format): Also accept ` ' and `'' as valid
        format flag characters.
        Do not require that a field width be specified.
        Do not fail when given a field width of `0'.
        Reported by Dan Jacobson.
        * tests/seq/basic: Add new tests for the above-fixed bug.

        * src/Makefile.am (all-local): Append $(EXEEXT) to use of `su'
        (install-root): Likewise.
        (install-exec-local): Likewise.
        Based on a patch from Richard Dawe.

2003-03-19  Jim Meyering  <jim@meyering.net>

        * man/Makefile.am (.x.1): Use $(LN_S) instead of 'ln -s',
        because the DJGPP 2.03 port of 'ln -s' doesn't work.
        Include $(EXEEXT) in program names.
        Since $(LN_S) may degenerate to `cp -p', be careful
        to invoke it from the destination directory.
        Mostly from Richard Dawe.
        * configure.ac: Use AC_PROG_LN_S.

        * tests/mv/part-symlink: Unset CDPATH.  Otherwise, having the
        CDPATH shell variable set could cause this test to fail.
        Reported by Karl Berry.

2003-03-18  Jim Meyering  <jim@meyering.net>

        * src/fmt.c [struct Word] (paren, period, punct, final): Change the
        type of each member from bool <MEMBER>:1 to unsigned int <MEMBER>:1.
        AIX 5.1's xlc could not compile the former.
        Patch by Petter Reinholdtsen.  Also reported by Mike Jetzer.

2003-03-17  Richard Dawe  <rich@phekda.freeserve.co.uk>

        * configure.ac: Include $(EXEEXT) in OPTIONAL_BIN_PROGS'
        program names, since automake only adds $(EXEEXT) to programs
        in its *_PROGRAMS.

2003-03-16  Jim Meyering  <jim@meyering.net>

        * src/remove.c (rm): Put two local variables in static storage,
        so they can't be clobbered by the potential longjmp.

2003-03-15  Jim Meyering  <jim@meyering.net>

        * Makefile.cfg (gnu_rel_host): Fix code to match the comment
        so that a version number with a two-digit component can still count
        as an alpha release.  Reported by Richard A Downing.
        (gnu_rel_host): Define in terms of $(RELEASE_TYPE) instead.

2003-03-14  Jim Meyering  <jim@meyering.net>

        * src/ansi2knr.c: Remove no-longer-used file.
        * src/ansi2knr.1: Likewise.

        * Makefile.maint (prev_version_file): Don't use ?= for this particular
        assignment, since it causes trouble with old versions of GNU make
        (e.g. 3.76.1).  The other uses of `?=' are inoffensive.  Details here.
        http://mail.gnu.org/archive/html/bug-coreutils/2003-03/msg00028.html
        Patch from Alexandre Duret-Lutz.

        * Use patched automake-1.7.3.  Regenerate Makefile.in files in
        subdirectories so that each includes a definition of ACLOCAL_M4.

        * announce-gen (main): Label the compressed source URLs.

        * Version 4.5.10.

        * tests/du/slink: Relax the test for the `local'ness of a file system,
        so that now it works also for tmpfs.

        * tests/du/hard-link: Transform output from first du, so that this
        test doesn't fail on file systems like tmpfs that order directory
        entries differently.

2003-03-13  Jim Meyering  <jim@meyering.net>

        * tests/du/8gb: Work around what appears to be an NFS failure that
        would make this test fail on some systems.

2003-03-11  Jim Meyering  <jim@meyering.net>

        * tests/du/basic: Make the test file exactly 4k bytes long.

        * src/split.c (longopts): Don't hard-code `2' here.
        Instead, just specify `&verbose', and ...
        (main): ... remove the `case 2:' block for --verbose.

        * tests/du/basic: Make the test file larger than 64 bytes, so that
        we don't immediately disqualify file systems (e.g., NetApp) on which
        smaller files take up zero disk blocks.  Reported by Vin Shelton.

2003-03-10  Jim Meyering  <jim@meyering.net>

        Don't segfault for a negative field width or precision in format string.
        Note that this is just a stopgap fix.  The longer term solution may
        involve adapting bash's builtins/printf.def.

        * src/printf.c: (UNSPECIFIED): Define.
        (print_direc): Use the special value, UNSPECIFIED, to indicate
        that field_width or precision has not been specified.
        (print_formatted): Fail if field_width or precision is the
        special value, UNSPECIFIED.
        Reported by Oliver Kiddle <okiddle@yahoo.co.uk>

        * src/sys2.h (INT_MIN): Define, if necessary.
        * tests/misc/printf: Add a test for the above-fixed bug.

2003-03-09  Jim Meyering  <jim@meyering.net>

        * src/remove.c (AD_stack_pop): Cast sizeof... to int before
        changing its sign.  This avoids a warning from gcc on 64-bit systems.
        Reported by Bob Proulx.
        (pop_dir): Reverse order of sign change and cast, to be consistent
        with the above.

2003-03-08  Jim Meyering  <jim@meyering.net>

        * tests/Makefile.am (evar-check): Check for POSIXLY_CORRECT not as a
        shell variable, but only in the environment.  With /bin/sh->bash, the
        shell variable is set to `y', and that would cause a spurious warning.
        Reported by Bob Proulx.

        * tests/Makefile.am (check-root): Remove touch/fifo.
        It doesn't appear to have to be run as root.

        * tests/rm/fail-2eperm: Rather than simply using the first non-root
        user name, make sure that the selected user name has a usable shell.
        Reported by Paul Jarc.

        Before, when using shred on a device, one had to specify --exact,
        or be careful to choose a size that would not be rounded up and
        exceed the maximum value;  that could result in a failure of
        the final write.
        * src/shred.c (do_wipefd): --exact is now the default for non-regular
        files.  Suggestion from Ben Elliston.
        (usage): Say it.

        * tests/misc/tty-eof: Require at least version 1.11 of Expect.pm.
        Old versions of Expect.pm (e.g., 1.07) lack the log_user function.
        Patch by Bob Proulx.

        * src/Makefile.am (check-misc): Check for use of `defined' in
        #define directives.
        Change to $(srcdir) before running grep.

        * src/sleep.c: Remove now-unused #include and #define directives.

        * src/du.c (process_file): If a file's size is not being counted
        e.g., because it's a hard link to a file we've already counted,
        then don't print a line for it.

        * tests/du/hard-link: New test for the above-fixed bug.
        * tests/du/Makefile.am (TESTS): Add hard-link.

        `du -S' didn't work
        * src/du.c: Revert most of the `reorganization' change of 2003-02-20,
        and make the two-array approach work.

        * tests/du/basic: Correct/add tests for the above fix.
        Set LC_ALL, etc., now that we use sort.
        Check the block/size of a small file, too.
        Correct expected results for simple dir1/dir2/file case.
        Add another test of du -S.

2003-03-07  John David Anglin  <dave.anglin@nrc-cnrc.gc.ca>

        Avoid build failure with gcc on hppa1.1-hp-hpux10.20 (see GCC PR
        middle-end/9986).  As one of GCC's optimizations, it transforms a
        fputs_unlocked call to a fputc_unlocked call when the string is
        one character long.  However, hpux doesn't have fputc_unlocked.

        * expr.c (usage): Use putchar, not fputs, to output a single character.
        * ls.c (dired_dump_obstack): Likewise.
        * ptx.c (output_one_tex_line, output_one_dumb_line): Likewise.
        * stat.c (print_it): Likewise.

2003-03-07  Jim Meyering  <jim@meyering.net>

        * src/cp.c: Remove everything associated with mmap-stack.c.
        This reverts the two changes of 2003-02-21.
        * src/du.c: Remove everything associated with mmap-stack.c.
        This reverts the change of 2003-02-19.

2003-03-06  Jim Meyering  <jim@meyering.net>

        * tests/cp/same-file: Unset CDPATH.  Otherwise, having the
        CDPATH shell variable set could cause this test to fail.
        Reported by Karl Berry.

2003-03-05  Jim Meyering  <jim@meyering.net>

        * Version 4.5.9.

        * src/printf.c (print_esc): Remove pointless comparison of unsigned
        integer with zero, to avoid a warning from Intel's ecc.
        Reported by Nelson Beebe.

        * src/du.c (process_file): Sizes must all be of type uintmax_t.
        Otherwise, for files or totals that are too big, numbers would
        be truncated.  Patch mostly by Michael Stone.
        Reported by Ingo Saitz as Debian bug #183210.

        * tests/du/8gb: New test for the above-fixed bug.
        * tests/du/Makefile.am (TESTS): Add 8gb.

        * src/du.c (MAX_N_DESCRIPTORS): Use 3 * UTILS_OPEN_MAX / 4
        rather than UTILS_OPEN_MAX - 10.

2003-03-04  Jim Meyering  <jim@meyering.net>

        * README: Refer new feature discussion to bug-coreutils@gnu.org,
        rather than bug-gnu-utils, now that the former is better known.
        Suggestion from Göran Uddeborg.

        * src/stat.c (usage): Capitalize consistently.
        Reported by Göran Uddeborg.

        * Makefile.maint (rel-files): Include $(signatures), so that
        those files are also copied into $(release_archive_dir).

        * src/df.c (find_mount_point): Call error here, now that restore_cwd
        no longer does it.
        * src/remove.c (AD_pop_and_chdir): Likewise.

        * tests/Makefile.am (check-root): Add fail-2eperm.

2003-03-03  Jim Meyering  <jim@meyering.net>

        * src/remove.c (remove_cwd_entries): Include the full filename of
        the offending file, not just the basename.

        * tests/misc/tty-eof: Set $ME properly.

        * Makefile.maint (THIS_VERSION_REGEXP, PREV_VERSION_REGEXP):
        Remove now-unused variables.
        (tag-prev-version, prev-cvs-tag): Likewise.

        * src/remove.c (remove_cwd_entries) [!ROOT_CAN_UNLINK_DIRS]: Give an
        accurate diagnostic when failing to remove a file owned by some other
        user.  Reported by Ivo Timmermans via Michael Stone.
        This fixes Debian bug# 178471.

        * tests/rm/Makefile.am (TESTS): Add fail-2eperm.
        * tests/rm/fail-2eperm: New test, for the above-fixed bug.
        Based on a report from Ivo Timmermans.

2003-03-02  Jim Meyering  <jim@meyering.net>

        * src/copy.c (copy_internal) [un_backup]: When recovering from a
        failure to create a hard link, do not remove the entry associating
        the source dev/ino with the destination file name.
        * tests/mv/Makefile.am (TESTS): Add hard-3.
        * tests/mv/hard-3: New test, for the above-fixed bug.
        Inspired by a report from Iida Yosiaki.

2003-03-01  Jim Meyering  <jim@meyering.net>

        * src/df.c (print_header): Don't embed spaces in a separate `Type'
        header string.  Instead, put `Filesystem' and `Type' headers in the
        same string, so translators can use horizontal space as needed.
        Reported by Jean Charles Delepine.

2003-02-28  Jim Meyering  <jim@meyering.net>

        * src/copy.c (copy_internal): When link fails because of an
        existing destination file, unlink that file and try again.
        Reported by Iida Yosiaki.

        * tests/mv/Makefile.am (TESTS): Add hard-2.
        * tests/mv/hard-2: New test for the above-fixed bug.
        Based on a test case from Iida Yosiaki.

2003-02-26  Jim Meyering  <jim@meyering.net>

        * tests/du/basic: Don't test du's -b option here.  Directory byte
        counts are smaller (512 rather than 4096) on at least OSF/1 5.1
        and IBM AIX 4.2.  Reported by Nelson Beebe.

2003-02-25  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (announcement): Now that ChangeLog entries
        are output by announce-gen, don't do it here.
        * announce-gen (print_changelog_deltas): New function.
        (main): Use it.

2003-02-22  Jim Meyering  <jim@meyering.net>

        * announce-gen: New option: --release-type=TYPE
        * Makefile.maint (beta, major): New targets.  Remove `release'.
        Put them all together on a line.
        Pass the release type (via RELEASE_TYPE envvar) to the MAKE
        invocation of `announcement'.
        (announcement): Invoke announce-gen with --release-type=$RELEASE_TYPE.

        * announce-gen: New option: --news=NEWS_FILE.
        Extract NEWS entries here, not via rules in Makefile.maint.
        * Makefile.maint (announcement): Now that NEWS entries are
        extracted by announce-gen, don't do it here.
        (news-r1, news-r2): Remove now-unused definitions.

2003-02-21  Jim Meyering  <jim@meyering.net>

        * Version 4.5.8.

        Merge in changes from autoconf's version of this file.
        * Makefile.maint (www-gnu): Define.
        (standards.texi-url_prefix): Use $(www-gnu).
        (make-stds.texi-url_prefix): Likewise.

        * src/cp.c: Include "mmap-stack.h".
        (main): Invoke `run' through a macro that (when possible) runs it
        with a large, mmap'd stack.

        * src/cp.c (run): New function, preparing for the above.
        Exit from this function, not from main
        (main): Call run.

        * src/du.c: New option: --apparent-size.
        (enum) [APPARENT_SIZE_OPTION]: New member.
        (long_options): Add it.
        (usage): Describe it.
        (main): Handle it.
        ['b']: Set apparent_size.
        David Eisner reported that the behavior of --bytes had changed.
        Paul Eggert proposed the use of a new option, --apparent-size.

        * src/du.c (apparent_size): New global.
        (print_only_size): Reflect the fact that we're printing byte counts,
        not ST_NBLOCKSIZE-byte-block counts.
        (print_size): Call print_only_size rather than duplicating its code.
        (process_file): Accumulate byte counts, rather than block counts.

        * src/du.c (process_file): Always reset size_to_propagate_to_parent
        for --separate-dirs (-S).

2003-02-20  Jim Meyering  <jim@meyering.net>

        * Use automake-1.7.3.  Regenerate dependent files.

        * src/stat.c (print_stat): New format: %B (to print ST_NBLOCKSIZE).
        This makes %b (number of ST_NBLOCKSIZE-byte blocks) more useful.
        (usage) [%B]: Describe it.
        [%b]: Refer to %B.

        * src/du.c (process_file): Reorganize the code to use only
        one `sum' array, and change how -S works back to the way it was
        before 2003-01-31.  Patch by Bruno Haible.

        * tests/du/basic: New test.
        * tests/du/Makefile.am (TESTS): Add basic.

        * tests/envvar-check: Add checks for the following:
        BLOCK_SIZE, DU_BLOCK_SIZE, DF_BLOCK_SIZE, LS_BLOCK_SIZE.

        * tests/Makefile.am: Rename phony target envvar-check to evar-check
        so as not to conflict with the distributed file by the same name.

        * src/du.c (process_file): Set info->skip before any possible return.

        Report correct usage for directories, not 0.
        * src/du.c (process_file): Return for `file_type == FTW_DPRE'
        _before_ recording the dev/ino of a directory.
        Reported by Bruno Haible.

        Now, df always displays the device file name corresponding to the
        listed mount point under `Filesystem'.  Before, for an unmounted
        block- or character-special file argument, it would display the
        command-line argument instead.
        * src/df.c (show_disk): Return a value indicating whether
        there was a match.  Don't try to find a mount point here.
        (show_entry): If show_disk doesn't find a match, call show_point.

2003-02-19  Jim Meyering  <jim@meyering.net>

        * src/du.c: Include "mmap-stack.h".
        (du_files): Add prototype with ATTRIBUTE_NORETURN.
        Exit from this function, not from...
        (main): ...here.
        Instead, if possible, invoke du_files through a macro that
        runs it with a large, mmap'd stack.

        * src/join.c (usage): Change wording in --help output:
        use FILENUM instead of `SIDE' and say what FILENUM means.
        Reported by Bernhard Gabler.

        * src/df.c (print_header): Rather than using a hard-coded literal
        string of spaces matching the length of the English `...Type' header,
        output the right number of spaces to match the selected translation.
        Reported by Yann Dirson and Jean Charles Delepine as Debian bug 131113.

        * src/split.c (bytes_split): Remove unnecessary `else' after break.
        (lines_split): Likewise.  and correct misleading indentation.

        * src/split.c: Include "full-read.h".
        (bytes_split, lines_split, line_bytes_split): Use full_read,
        not safe_read.   The way split was using the latter, a short read
        could cause split to terminate before EOF.

        * tests/misc/tty-eof: Test all programs that can read stdin,
        requiring no arguments and that write to standard output.

        * tests/misc/tty-eof: New file.  Renamed from ...
        * tests/misc/cat-tty-eof: Remove file.  Rename to tty-eof.
        * tests/misc/Makefile.am (TESTS): Reflect renaming.

2003-02-18  Jim Meyering  <jim@meyering.net>

        cksum would perform an extra read after encountering EOF
        * src/cksum.c (cksum): Exit the loop upon EOF, too.
        Patch by Michael Bacarella.

        Test for the bug fixed today in cksum, md5sum, and sha1sum.
        * tests/misc/cat-tty-eof: Generalize, clean-up, and test for
        cat, cksum, md5sum, and sha1sum all in the same loop.

2003-02-14  Jim Meyering  <jim@meyering.net>

        * src/remove.c: Include "euidaccess.h".
        Remove declaration of euidaccess.

2003-02-12  Jim Meyering  <jim@meyering.net>

        * src/pathchk.c (portable_chars_only): Remove unnecessary `const'
        in cast to avoid warning from icc.  Reported by Alexandre Duret-Lutz.

2003-02-10  Jim Meyering  <jim@meyering.net>

        * src/test.c: Don't include group-member.h.
        Include euidaccess.h.
        (eaccess): Rewrite function to set the real uid and gid temporarily
        to the effective uid and gid, then invoke 'access', and then set the
        real uid and gid back.  On systems that lack setreuid or setregid,
        fall back on the kludges in euidaccess.  Before, it would not work
        for e.g., files with ACLs, files that were marked immutable,
        or on file systems mounted read-only.  Nelson Beebe raised the issue.
        Paul Eggert suggested the new implementation.

2003-02-09  Jim Meyering  <jim@meyering.net>

        * src/test.c (test_stat): Remove function.  It's job is done (only
        when necessary) by the wrapper in lib/stat.c.  Adjust all uses.

2003-02-08  Jim Meyering  <jim@meyering.net>

        * Version 4.5.7.

        * tests/mv/part-symlink: Don't assume that the file owner username
        length is less than 9 in ls output: instead, omit that field
        altogether.  Reported by, and suggested fix from, Ferdinand.

        * tests/du/restore-wd: New test for just-fixed bug in ftw.c.
        * tests/du/Makefile.am (TESTS): Add restore-wd.

        * src/rm.c: Correct now-invalid comment about cycle-detection.

2003-02-06  Jim Meyering  <jim@meyering.net>

        * NEWS: Add entries from old/*/NEWS
        from fileutils-4.1 through 4.1.11 and
        from sh-utils-2.0 through 2.0.15.  Suggestion from Karl Berry.

        * Version 4.5.6.

        * src/du.c (process_file): Don't return early for excluded files
        or for files whose dev/inode we've already seen.

        Fix memory allocation arithmetic.

2003-02-04  Jim Meyering  <jim@meyering.net>

        `df /dev/block-or-char-device-file--not-mounted' now reports
        the name of the file system on which the file resides, usually `/'.
        Before, it would leave the `Mounted on' field blank.
        * src/df.c (show_disk): Move function to precede find_mount_point.
        (show_disk): Add parameter: STATP.
        If we don't find a matching device name, then resort to calling
        find_mount_point.  Reported by Bob Proulx.

        (main): Fail if G_fail is set.

2003-01-31  Richard Dawe  <rich@phekda.freeserve.co.uk>

        * tests/basename/Makefile.am: Use @PATH_SEPARATOR@ instead of
        hard-coding the path-separator.  Also double-quote the new PATH,
        to avoid problems when the path-separator is a semi-colon or when
        `pwd` contains e.g. a space.

        * src/stat.c: Include "file-type.h"
        (print_human_type): Remove function.
        (human_access): Rename from print_human_access.  Return a string.
        (human_time): Rename from print_human_time.  Return a string.
        (print_stat): Arrange so that field width and an alignment specifier
        are honored for the %A, %F, %x, %y, and %z formats.
        [%F]: Use file_type; this gives slightly different file type strings,
        e.g., `directory' instead of `Directory' and `regular file' or
        `regular empty file' instead of `Regular file'.
        Prompted by a report from Richard Dawe that the uses of
        S_IFSOCK and S_IFIFO in print_human_time were not portable
        to systems using e.g., DJGPP.

2003-01-31  Richard Dawe  <rich@phekda.freeserve.co.uk>

        * src/stat.c (print_stat): Use S_ISLNK rather than an explicit
        test using S_IFMT and S_IFLNK.  S_IFLNK may not be defined.

2003-01-31  Jim Meyering  <jim@meyering.net>

        * src/du.c (main): Upon processing an invalid option or an invalid
        --exclude-from or --max-depth option argument, don't exit right away,
        in case there are others.  Rather record the failure and exit after
        processing other options.

        * GNUmakefile (TAR_OPTIONS): Set and export, in order to make
        tar archive easier to reproduce.

        Rewrite to perform directory traversal using nftw.

        * src/du.c: Include "dirname.h", "ftw.h", and "quotearg.h".

        (arg_length, suffix_length): New globals.

        symlink-to-directory with -L, even without the trailing slash.

2003-01-27  Jim Meyering  <jim@meyering.net>

        * src/Makefile.am (check-misc): Check for st_blocks, too.

        Reported by Richard Dawe.

2003-01-27  Andreas Schwab  <schwab@suse.de>

        * src/ls.c (quote_name): Add fourth parameter, width, into which to
        store the screen columns, and return the number of bytes instead.
        (print_dir): Pass NULL as fourth parameter of quote_name.
        (print_name_with_quoting): Likewise.
        (length_of_file_name_and_frills): Get the width from the fourth
        parameter of quote_name instead of return value.

2003-01-27  Jim Meyering  <jim@meyering.net>

        * src/ls.c (decode_switches): If `dired' is set without
        `format == long_format', then silently reset dired.  This doesn't
        change the behavior of ls (all prior uses of dired were protected
        by `&& format == long_format'), and lets us...
        (DIRED_INDENT): ... remove the `format == long_format' conjunct.
        (PUSH_CURRENT_DIRED_POS): Likewise.
        (main): Likewise.

2003-01-22  Jim Meyering  <jim@meyering.net>

        * src/remove.c (remove_entry) [ROOT_CAN_UNLINK_DIRS
        && HAVE_STRUCT_DIRENT_D_TYPE]: If a file has d_type == DT_UNKNOWN
        it may still be a directory -- or not (e.g., with FreeBSD on an
        NFS-mounted file system), so resort to calling lstat to find out.
        Based on a patch by Michael van Elst.

        * tests/cp/same-file: Don't assume that the file owner username
        length is less than 9 in ls output: instead, omit that field
        altogether.  Reported by, and suggested fix from, Ferdinand.

2003-01-20  Jim Meyering  <jim@meyering.net>

        * tests/date/Test.pm (wide-fmt): New test to demonstrate that
        large format widths no longer cause strftime to infloop.

        * Makefile.maint (mail_gpg_sign_cookie): Remove now-unused definition.

2003-01-19  Jim Meyering  <jim@meyering.net>

        * src/readlink.c: Include "canonicalize.h".

2003-01-18  Jim Meyering  <jim@meyering.net>

        * src/ls.c (Dereference_symlink) [DEREF_COMMAND_LINE_SYMLINK_TO_DIR]:
        New member.
        (enum) [DEREFERENCE_COMMAND_LINE_SYMLINK_TO_DIR_OPTION]: New member.
        (long_options): Add option --dereference-command-line-symlink-to-dir.
        (main): Make DEREF_COMMAND_LINE_SYMLINK_TO_DIR be the default,
        rather than DEREF_COMMAND_LINE_ARGUMENTS, when none of the
        -d, -F, -l options is specified.
        (decode_switches): Handle --dereference-command-line-symlink-to-dir.
        (gobble_file): Honor DEREF_COMMAND_LINE_SYMLINK_TO_DIR.
        Change --dereference-command-line (-H) to dereference *all*
        command line arguments, including broken symlinks.

2003-01-15  Paul Eggert  <eggert@twinsun.com>

        Change ls -H back to the way it was yesterday, since this is
        compatible with FreeBSD and the POSIX spec is confusing
        and somewhat contradictory.

        * src/ls.c (DEREF_COMMAND_LINE_ARGUMENTS): Change name back
        from DEREF_COMMAND_LINE_SYMLINK_TO_DIR, updating all uses.
        (long_options): Change the long option name back.
        (usage): Change the usage back.
        (gobble_file): When -H is specified, dereference a top-level
        arg even if it points to a non-directory.

2003-01-15  Jim Meyering  <jim@meyering.net>

        * src/ls.c (gobble_file): Fall back on using lstat when required:
        when --dereference (-L) is not specified, and
        - when operating on a dangling symlink
        - when operating on command-line-symlink-to-directories
        This fixes numerous problems.  Here are examples:
        - `ls dangling-symlink' would fail with `no such file...'
        Now it prints `dangling-symlink'.
        - `ls -i symlink' would mistakenly print the inode of the referent.
        Now it prints the inode of the symlink.  Likewise for --size (-s).
        Based on a patch from Michael Stone.
        Reported by Deepak Goel as Debian bug #173793.

        Rename ls's --dereference-command-line (-H)
        option to   --dereference-command-line-symlink-to-dir.
        * src/ls.c [enum Dereference_symlink]
        (DEREF_COMMAND_LINE_SYMLINK_TO_DIR): Rename from
        DEREF_COMMAND_LINE_ARGUMENTS.  Update all uses.
        (long_options): Rename the long option.
        (usage): Say that --dereference-... changes how ls treats
        only symlinks to directories specified on the command line.

2003-01-14  Jim Meyering  <jim@meyering.net>

        * tests/ls/dangle: New file/test, for the above fix.
        * tests/ls/inode: Another new file/test, for the above fix.
        * tests/ls/Makefile.am (TESTS): Add dangle and inode.

        * src/ls.c (gobble_file): Fix a bug introduced in 4.5.4 that made it
        so that ls --color would no longer highlight the names of files with
        the execute bit set when not specified on the command line.
        Patch by Michael Stone.  Reported by Stephen Depooter as
        Debian bug 175135.

        * tests/ls-2/tests (color-exe): New test, for the above fix.

2003-01-13  Jim Meyering  <jim@meyering.net>

        * src/shred.c (long_opts): --zero does not require an argument.
        Patch by Michael Stone.  Reported by Roland Turner as Debian bug 172019.

2003-01-12  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (cvs-update): Skip any file with local modifications.

        * tests/cut/Test.pm: New tests for the above.

        * src/cut.c (set_fields): Make code agree with comment:
        Don't merge abutting ranges like 4- and 2-3.  This makes no
        difference currently, but is required to support an upcoming change.

2003-01-07  Jim Meyering  <jim@meyering.net>

        * src/cut.c (set_fields): Fix typo in comment.

        * tests/touch/not-owner: New test, mostly extracted from fail-diag.
        * tests/touch/Makefile.am (TESTS): Add not-owner.

        * src/mknod.c (usage): Specify how major and minor mode numbers
        are interpreted.  Report forwarded by Kristin E Thomas.
        * src/mknod.c: Remove now-redundant usage-specifying comment.

2002-12-13  Jim Meyering  <jim@meyering.net>

        * Version 4.5.4.

        * tests/du/trailing-slash: Allow for a directory of size `0'.
        That happens at least on file systems of type tmpfs on linux-2.4.18.

        * announce-gen: New script to begin replacing the commands
        associated with the rule here...
        * Makefile.maint (announcement): Invoke announce-gen.
        * Makefile.am (EXTRA_DIST): Add announce-gen.

        * tests/cp/preserve-2: New file/test, for latest fix.

        Fix a bug whereby cp would fail to parse an option like
        --preserve=mode,ownership.
        * src/cp.c (decode_preserve_arg): Advance `comma' to
        point the character following the comma.

2002-12-11  Jim Meyering  <jim@meyering.net>

        * src/pathchk.c (NEED_PATHCONF_WRAPPER): Undefine before defining,
        in case it's already defined.

2002-12-09  Jim Meyering  <jim@meyering.net>

        * tests/touch/fail-diag: Don't get a test failure if /no exists.
        Instead, evoke a framework failure if /no-$$ exists.
        Reported by Michael Stone.

2002-12-08  Jim Meyering  <jim@meyering.net>

        * src/du.c (lstat) [! LSTAT_FOLLOWS_SLASHED_SYMLINK]:
        Define to rpl_lstat, so that even on systems like Solaris 5.8,
        du honors (per POSIX) the trailing slash on an argument referring
        to a symlink-to-directory.

2002-12-06  Jim Meyering  <jim@meyering.net>

        * Use autoconf-2.57.  Regenerate dependent files.
        * Use automake-1.7.2.  Regenerate dependent files.

        * src/ls.c (gobble_file): Also stat the file if it's a
        regular file and --indicator-style=classify (aka -F).
        Thanks to Ed Santiago for opening my eyes.

        * tests/ls/file-type: New file.  Test for the above.
        A test to contrast ls -F and ls --indicator-style=file-type.
        * tests/ls/Makefile.am (TESTS): Add file-type.

2002-12-04  Jim Meyering  <jim@meyering.net>

        * tests/ls/follow-slink: Make sure the symlink was created.
        Richard Dawe reported that `ln -s link link' succeeds, but creates
        no file on systems running some version of the DJGPP libc.

2002-12-03  Jim Meyering  <jim@meyering.net>

        * src/Makefile.am (AUTOMAKE_OPTIONS): Remove definition (to ansi2knr)
        since this package no longer panders to K&R compilers.

2002-12-02  Jim Meyering  <jim@meyering.net>

        * tests/du/slink: Skip this test if `.' is on a non-local file system.

        * tests/Fetish.pm (_at_replace): Do the substitution only if there's
        something to replace.

2002-12-01  Jim Meyering  <jim@meyering.net>

        * src/stat.c: Don't include <string.h> or <ctype.h>.
        That's already done via system.h.
        * src/dircolors.c: Don't include <ctype.h>.

2002-11-30  Jim Meyering  <jim@meyering.net>

        * ls.c (gobble_file): Remove the block of code that caused
        `ls --color -F symlink-to-dir' to list the files in
        `symlink-to-dir/.'.  Now, it prints `symlink-to-dir@', (just
        like `ls -F symlink-to-dir') but with the addition of highlighting.
        Similarly, `ls --color -dF symlink-to-dir' would print
        `symlink-to-dir/';  now it prints `symlink-to-dir@'.
        Reported by Jeff Sheinberg as Debian bug #168203.
        * tests/ls-2/tests (sl-F-color, sl-dF-color): New tests for the above.

        ls is now more efficient: with certain options, it no longer needs
        to stat each directory entry on systems with valid dirent.d_type.
        * src/ls.c (print_dir): Add DT_LNK and DT_REG.
        (main): Make --recursive set format_needs_type, not format_needs_stat.
        (gobble_file): Remove a FIXME comment, now that it's fixed.

2002-11-24  Jim Meyering  <jim@meyering.net>

        * src/du.c (du_files): Don't strip any trailing slash.
        Rewrite so that `/' is no longer represented internally as
        the empty string.
        (count_entry): When appending a file name component,
        account for the fact that the current path may end in `/'.
        François Pinard reported that `du symlink-to-dir/' was not
        equivalent to `du symlink-to-dir/.'.  Now it is.
        * tests/du/trailing-slash: New file/test, for the above fix.
        * tests/du/Makefile.am (TESTS): Add trailing-slash.

2002-11-23  Jim Meyering  <jim@meyering.net>

        * src/tac.c (output): Declare some local variables to be of type size_t,
        rather than `int' to avoid warnings from gcc.

2002-11-21  Paul Eggert  <eggert@twinsun.com>

        * src/ls.c (decode_switches): Use case-sensitive matching to
        decode the QUOTING_STYLE environment variable.  This is more
        consistent with the documentation, and with --quoting-style.

2002-11-21  Martin Buck  <martin.buck@ascom.ch

        * src/stty.c (struct speeds): Add support for all baud rates defined
        in linux-2.4.19.

2002-11-19  Jim Meyering  <jim@meyering.net>

        * tests/sum/sysv: Export LC_ALL=C, to avoid failure when
        run in a UTF locale.  Report and suggested fix by Bruno Haible.
        * tests/fmt/basic: Likewise.

2002-11-17  Jim Meyering  <jim@meyering.net>

        * configure.ac: Update via autoupdate.
        Add `AM_GNU_GETTEXT_VERSION(0.11.5)'.

        * src/mv.c (movefile): Don't remove trailing slashes from SOURCE.
        Reported by Hans Ginzel.

2002-11-15  Jim Meyering  <jim@meyering.net>

        * Makefile.cfg (gnu_rel_host): Define.
        (url_dir_list): Choose from (alpha|ftp).gnu.org depending
        on whether $(VERSION) looks like a major release number.

        * Makefile.maint (mail_gpg_sign_cookie): Backslash-escape `#'.
        (release): Rename from `alpha'.
        (alpha): Depend on release.

        * Makefile.maint (signatures): Define with ?=, so it's easy to override.

2002-11-14  Jim Meyering  <jim@meyering.net>

        * Makefile.maint (mail_gpg_sign_cookie): Make optional.
        (announcement): Use the new variable.

        * Makefile.maint: Sync with Bison, i.e.:
        (po-check): Scan .l and .y files instead of the
        .c and the .h files that they generate.  This fixes the bug
        reported by Tim Van Holder in:
        <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
        Look for N_ as well as for _.  Try to avoid matching #define for
        N_ and _.
        From Paul Eggert.

2002-11-12  Jim Meyering  <jim@meyering.net>

        * src/ls.c (HAVE_SYMLINKS): Remove unnecessary macro definition.
        Replace sole use with equivalent `#ifdef S_ISLNK'.
        Inconsistency reported by Dmitry V. Levin.

2002-11-11  Jim Meyering  <jim@meyering.net>

        * src/stat.c (usage): Transform --help items output via s/ - /   /,
        so that help2man produces properly formatted man pages.
        Reported by Herbert Xu as Debian bug #168400.

2002-11-10  Jim Meyering  <jim@meyering.net>

        * src/ls.c (sighandler): Handle SIGTSTP specially.
        Based on suggestions from Solar Designer and Dmitry V. Levin.
        Add comments.

        * Makefile.cfg (cvs_files): Define.  From autoconf.
        (local_updates): Likewise.

        * src/ls.c (restore_default_color_handler, sigtstp_handler):
        Remove functions.
        (sighandler): New function, based on the one in sort.c.
        (main): Use sigaction, if possible; otherwise signal.
        Handle these signals:
        SIGHUP, SIGINT, SIGPIPE, SIGQUIT, SIGTERM, SIGTSTP.
        Don't register our handler if the signal is already being ignored.

        * src/dd.c (interrupt_handler): Use raise, rather than kill+getpid.
        * src/csplit.c (interrupt_handler): Likewise.
        * src/sort.c (sighandler): Likewise.
        (main): Declare `i' and `nsigs' to be unsigned, not int.

2002-11-09  Jim Meyering  <jim@meyering.net>

        ls --color: restore terminal text color upon signal.
        * src/ls.c: Include "full-write.h" and <signal.h>.
        (restore_default_color, restore_default_color_handler): New functions.
        (sigtstp_handler, put_indicator_direct): New functions.
        (main) [print_with_color]: Register signal handlers.
        Patch mostly by Solar Designer and Stanislav Ievlev.

        Update from autoconf.
        * Makefile.maint (AMTAR): Remove definition.
        (update, cvs-update, po-update, do-po-update): New rules.
        (wget-update): Update (thus renaming to cvs-update).
        (automake_repo): Use anoncvs@sources.redhat.com.

2002-11-06  Jim Meyering  <jim@meyering.net>

        * tests/misc/Makefile.am (TESTS): Add printf-hex.

        * tests/misc/printf: Be careful to test the code in this package,
        not the shell built-in function.

        * src/printf.c (print_esc): A hexadecimal escape sequence has
        at most two hex. digits, not three.  Reported by Padraig Brady.
        (usage): Update description.
        * tests/misc/printf-hex: New file/test, for the above fix.

2002-10-07  Paul Eggert  <eggert@twinsun.com>

        Add support for locale-specific size indications (e.g.,
        thousands-separators) and for explicit size suffixes on output.

        * doc/coreutils.texi (Block size): Say that:
        This affects display format as well as block size.
        Fractional block counts are rounded up.
        ls file size blocksize defaults to 1.
        A block size spec preceded by ' generates thousands separators.
        A suffix without a preceding integer generates suffixes.
        (tail invocation): 32k -> 32 KiB.
        (What information is listed): ls -h is now equivalent to
        ls --block-size=human, and ls -H is now equivalent to
        ls --block-size=si.  Displayed file size is now always affected by
        --block-size.

        * lib/inttostr.c, lib/inttostr.h, lib/imaxtostr.c, lib/offtostr.c,
        lib/umaxtostr.c: New files, taken from GNU tar.

        * lib/Makefile.am (libfetish_a_SOURCES): Add imaxtostr.c, offtostr.c,
        umaxtostr.c.
        (EXTRA_DIST): Add inttostr.c.

        * lib/human.c, lib/human.h: Rewrite to support locale-specific
        notations like thousands separators.
        Specify what includer of include.h must include beforehand.
        (human_group_digits, human_suppress_point_zero, human_autoscale,
        human_base_1024, human_SI, human_B): New enum values.
        (human_readable): Rename from human_readable_inexact; put the
        options before the sizes.  All uses changed.  The old human_readable
        function has been removed; use inttostr.h instead.
        (human_options): Renamed from human_block_size, with new signature
        that allows block sizes up to UINTMAX_MAX.  All callers changed.

        * m4/prereq.m4 (jm_PREREQ_HUMAN): Check for locale.h, localeconv,
        AC_HEADER_STDBOOL.  No need to check for limits.h since it's in
        freestanding C89.  No need to check for stdlib.h or string.h since
        autoconf does this now.

        * src/cksum.c (cksum): Use primitives from inttostr.h, not
        human.h, to print large numbers simply.
        * src/csplit.c (handle_line_error, parse_patterns): Likewise.
        * src/dd.c (print_stats, main): Likewise.
        * src/df.c (print_header): Likewise.
        * src/factor.c (print_factors): Likewise.
        * src/ls.c (print_long_format, print_file_name_and_frills): Likewise.
        * src/shred.c (dopass): Likewise.
        * src/sort.c (checkfp): Likewise.
        * src/sum.c (bsd_sum_file, sysv_sym_file): Likewise.
        * src/tail.c (xlseek): Likewise.
        * src/wc.c (write_counts, wc): Likewise.

        * src/df.c (human_output_opts): New var.
        (output_block_size): Now uintmax_t, not int, to handle larger
        block sizes.  All uses changed.
        * src/du.c: Likewise.
        * src/ls.c: Likewise.

        * src/df.c (print_header): In the header line, prefer SI to human
        representation if it's shorter; if neither is shorter, try to
        intuit what the user would prefer.

        * src/expr.c (inttostr): Remove; use new imaxtostr library
        function instead.

        * src/ls.c (file_output_block_size): New var, to distinguish
        file sizes from other sizes.
        (decode_switches): Set it.

        * src/shred.c (OUTPUT_BLOCK_SIZE): remove.
        (dopass): When printing progress, use floor for what has been done
        so far (since we should be conservative there), and ceiling for
        what needs to be done (since that's what other programs use).

2002-10-19  Jim Meyering  <jim@meyering.net>

        * src/pinky.c (print_heading): Align TTY and Name headings.
        Reported by Karl Eichwalder.

2002-10-18  Jim Meyering  <jim@meyering.net>

        * src/split.c (cwrite): Change type of `bytes' parameter to size_t
        Remove now-useless cast.
        (stdread): Remove function.
        (bytes_split): Use size_t instead of int.
        Use safe_read, not stdread.
        (lines_split): Likewise.
        Use memchr rather than a `while' loop.
        (line_bytes_split): Use size_t instead of int.
        Use safe_read, not stdread.
        (main): Add some FIXME comments to remind me to remove casts.

        * src/system.h (ST_BLKSIZE): Correct comment describing how to
        reproduce HPUX-11 cat failure.  From Petter Reinholdtsen.

2002-10-17  Jim Meyering  <jim@meyering.net>

        Fix a problem that could make e.g., `cat' misbehave on systems which
        give invalid (unreasonably large) values for stat.st_blksize.
        * src/system.h (ST_BLKSIZE): Ensure that the result is in [1..4MB].
        Reported by Petter Reinholdtsen.

2002-10-14  Jim Meyering  <jim@meyering.net>

        Specifying a printf conversion specifer as nl's separator string
        could cause nl to segfault.
        * src/nl.c (build_print_fmt): Don't include separator string
        in the printf format; it might contain `%'.
        Use a better bound on the length of the print_fmt buffer.
        (print_lineno): Print the separator here instead.
        Reported by Doug Coleman.

        * tests/misc/nl: New file/tests, including a test for the above.
        * tests/misc/Makefile.am (TESTS): Add nl.

        * tests/misc/split-l: New test, to make sure `split --lines=N' works.
        * tests/misc/Makefile.am (TESTS): Add split-l.

2002-10-13  Jim Meyering  <jim@meyering.net>

        * Version 4.5.3.

        * src/du.c (usage): Tweak description of --dereference-args/-D.

        * src/du.c (count_entry): Also save cwd when dereferencing (via
        --dereference-args, -D) a command-line argument.
        Reported by Michal Svec.  Based on a patch by Andreas Schwab.

        * src/Makefile.am (../AUTHORS): New target/rule.

        * src/paste.c (paste_parallel): Declare local, `delims_saved', to be
        of type size_t, since that's the way it's used and avoids a warning.

        * src/csplit.c (struct cstring) [len]: Declare to be unsigned int,
        since that's how it's always used and avoids a new warning from gcc.
        (read_input): Adapt to new safe_read ABI.

        * src/cut.c (cut_fields): Add a temporary size_t variable, n_bytes,
        to avoid warnings.

        * src/pinky.c (print_long_entry): fread returns size_t.
        Declare local `bytes' accordingly, to avoid warning.

        tail -c +N would perform an extra read after encountering EOF
        [this change is analogous (bytes vs. lines) to the one of 2002-01-27]
        * src/tail.c (start_bytes): Detect EOF, inform caller.
        (tail_bytes): Upon EOF in start_bytes, return immediately.
        (file_lines): Reorganize to use memrchr rather than an explicit loop.
        Adapt to new safe_read ABI.

2002-10-11  Jim Meyering  <jim@meyering.net>

2002-10-09  Jim Meyering  <jim@meyering.net>

        * tests/cp/backup-is-src: Ensure that certain environment variables
        are not set (e.g., SIMPLE_BACKUP_SUFFIX).  Reported by Duncan Roe.

        * tests/tail-2/big-4gb: Mark this as an expensive test; it would
        consume 4GB of disk space on systems without support for sparse files.
        Fix a logic error that'd make it `cat err' even though dd didn't fail.

        * src/dircolors.hin (.jar): Fix typo: s/;3$/;31/.
        Patch by steven@magelico.net, forwarded by Michael Stone.

        * tests/ls/dired: Ensure that ls produces English messages.
        Patch by Alexey Vyskubov, forwarded by Michael Stone.

        Fix syntax in test: use =, not ==.
        Reported by Bob Proulx.
        Change all the rest like this: grep -lR "testing framework'" .\
        |xargs perl -pi -e 's/'\''(\$0: failure in testing framework)'\''/"$1"/'

        * src/sum.c (sysv_sum_file): Adapt to new safe_read ABI.

        * Makefile.maint (signatures): Define.
        (%.sig): New rule.

        * Makefile.maint (announcement): Output all URLs for detached
        signatures, not just the last one from the previous loop.

2002-10-05  Jim Meyering  <jim@meyering.net>

        * Version 4.5.2.

        * src/remove.c (remove_entry) [ROOT_CAN_UNLINK_DIRS]: With `rm -i DIR',
        don't recurse into directory, DIR.  Prompted by a report from
        Leonardo Milano.

        * tests/rm/i-no-r: New file/test, for the above fix.
        * tests/rm/Makefile.am (TESTS): Add i-no-r.

        * src/rm.c (AUTHORS): Mark translatable string with `N_ (...)'.
        * src/df.c (AUTHORS): Likewise.
        * src/du.c (AUTHORS): Likewise.
        * src/tail.c (AUTHORS): Likewise.
        * src/touch.c (AUTHORS): Likewise.

2002-10-02  Jim Meyering  <jim@meyering.net>

        * Makefile.am (SUBDIRS): Remove `old'.
        (EXTRA_DIST): List the files in old/.
        * configure.ac (AC_CONFIG_FILES): Remove old/* names.
        Suggestion from Akim Demaille.

2002-10-01  Jim Meyering  <jim@meyering.net>

        * src/sys2.h (SSIZE_MAX): Define.

2002-09-30  Jim Meyering  <jim@meyering.net>

        * src/csplit.c: Don't include stdlib.h here.  It's already included
        via system.h.

2002-09-29  Jim Meyering  <jim@meyering.net>

        * src/tr.c (find_bracketed_repeat): Rearrange pointer/integer
        expression to avoid bogus warning from gcc.

        * src/cat.c (simple_cat): Use a temporary to avoid bogus warnings.
        (cat): Declare insize and outsize to be of type size_t, not int.
        Rearrange pointer/integer expressions to avoid bogus warnings.
        (main): Declare insize and outsize to be of type size_t, not int.

        * src/tail.c (parse_options): Give a sensible diagnostic for
        an invalid byte or line count.  Reported by Mikko Tuumanen.

        * src/touch.c (main): Split a long line.

        * tests/du/Makefile.am (TESTS): Add slink.
        * tests/du/slink: New test for system.h change of 2002-08-31.

        In move mode, always first try to rename.  Before, upon failure to
        rename a directory, this code would never attempt to rename any
        other file in that directory, but would thenceforth always copy.
        On some systems (e.g., NetApp's OnTap-6.4), renaming a directory
        may fail with EXDEV, yet renaming files within that directory to
        a newly-created destination directory succeeds.
        * src/copy.c (copy_internal): Remove local, move_mode;
        use x->move_mode instead.  Based on a patch from Tom Haynes.

2002-09-28  Jim Meyering  <jim@meyering.net>

        * src/split.c (FAIL_ONLY_ONE_WAY): New macro.
        Factor out some duplication.
        (main): Use it.
        [case 'a']: Use strtoul rather than strtol to avoid compiler warnings.

        * src/sort.c (begfield, limfield): Rearrange comparisons to avoid
        compiler warnings.
        (fillbuf, keycompare): Cast literal `-1' to size_t in comparisons,
        to avoid compiler warnings.

        * src/shred.c (dopass): Use a uintmax_t temporary to avoid bogus
        compiler warnings.

        Fix things so `mkdir -p' can create very deep directories, e.g.,
        mkdir -p $(perl -e 'print "a/" x 40000') now works.
        * src/mkdir.c (main): For --parents (-p), call make_path with the
        entire directory name, so we don't ever require that file operations
        like stat or chmod be performed on the entire command line argument.
        * makepath.c (make_path): Restore umask *before* creating the final
        component.

2002-09-27  Andreas Schwab  <schwab@suse.de>

        * src/tail.c (tail_bytes): Change type of bytes_remaining to off_t
        to avoid overflow.  Reported by Hans Lermen.

2002-09-26  Jim Meyering  <jim@meyering.net>

        * src/install.c (get_ids): Use strtoul, not strtol.  Remove some casts.

2002-09-25  Jim Meyering  <jim@meyering.net>

        * src/test.c (eaccess): Change type of local `euid' from int to uid_t
        and add a cast, to avoid a warning about `signed and unsigned type in
        conditional expression'.

2002-09-22  Jim Meyering  <jim@meyering.net>

        * src/rmdir.c: Include "dirname.h", for declaration of
        strip_trailing_slashes.

        * src/stat.c (PRIdMAX, PRIuMAX): Remove definitions.
        Now they're defined through system.h.

        * src/cp-hash.c, src/dd.c, src/df.c, src/du.c, src/ls.c,
        * src/stat.c, src/wc.c: Remove all inclusions of inttypes.h,
        since it's already included from sys2.h via system.h.

        * Use automake-1.6f.  Regenerate dependent files.

        * src/Makefile.am (PERL): Remove duplicate definition.

        fmt's -s, -t, -c options didn't work properly for long lines.
        Since get_line may end up calling put_paragraph (for long lines),
        be sure to set global, `other_indent', before it is used there.

        * src/fmt.c (set_other_indent): New function, factored out of...
        (get_paragraph): ... here.  Call it.
        (get_line): Call set_other_indent before calling flush_paragraph,
        which calls fmt_paragraph, which in turn calls put_paragraph,
        which uses other_indent.

        * tests/fmt/Makefile.am (TESTS): Add long-line.
        * tests/fmt/long-line: New file/test, for the above fix.

2002-09-21  Jim Meyering  <jim@meyering.net>

        * src/od.c: No longer include deprecated <values.h>.
        It was required solely for now-removed reference to BITSPERBYTE.
        * src/install.c: Likewise.
        Suggestion from Bruno Haible.

2002-09-06  Andreas Schwab  <schwab@suse.de>

        `rmdir -p dir-specified-with-trailing-slash/' would fail.
        * src/rmdir.c (remove_parents): Strip trailing slashes.

2002-09-20  Jim Meyering  <jim@meyering.net>

        * tests/rmdir/t-slash: New file/test, for the above fix.
        * tests/rmdir/Makefile.am (TESTS): Add t-slash.

        * Makefile.maint (announcement): Arrange to gpg-sign the message.
        Add a URL for each detached signature file.

2002-09-07  Bruno Haible  <bruno@clisp.org>

        * configure.ac: Add need-ngettext to AM_GNU_GETTEXT invocation.

2002-09-18  Jim Meyering  <jim@meyering.net>

        `od -t x8' used the wrong (`l'-prefixed) printf format.
        Likewise for the o8 and u8 formats.
        * src/od.c (ISPEC_TO_FORMAT): Define macro.
        (decode_one_format): Use PRIdMAX, PRIoMAX, etc. for LONG_LONG.
        Reported by Arun Sharma.

2002-09-17  Jim Meyering  <jim@meyering.net>

        * src/sys2.h (PRIdMAX, PRIoMAX, PRIuMAX, PRIxMAX): Define if necessary.
        From gettext's intl/loadmsgcat.c.

        * tests/od/x8: New file/test, for the above fix.
        * tests/od/Makefile.am (TESTS): Add x8.

2002-09-15  Jim Meyering  <jim@meyering.net>

        * Use autoconf-2.54.  Regenerate dependent files.

        * src/csplit.c (get_format_width): Add cast to avoid
        warning about `signed and unsigned type in conditional expression'.

2002-09-14  Jim Meyering  <jim@meyering.net>

        * src/who.c (print_user): Change type of local to size_t
        to avoid warnings about `comparison between signed and unsigned'.
        * src/ptx.c (generate_all_output): Likewise.

        * src/dd.c (main, skip): Add casts to avoid warnings about
        `comparison between signed and unsigned'.

        * src/id.c (print_full_info, print_group_list): Add casts to avoid
        warnings about `signed and unsigned type in conditional expression'.

        * src/md5sum.c: Change type of global, digest_hex_bytes, to size_t
        to avoid warnings about `comparison between signed and unsigned'.
        (split_3): Change parameter names to be readable and add comment.
        Clean up the test for whether a line may be ignored.

2002-09-13  Jim Meyering  <jim@meyering.net>

        * src/printf.c (main): Handle leading command line argument of `--'.
        Reported by Raul: DervishD <raul@pleyades.net>
        * tests/misc/printf: New file: test for the above.
        * tests/misc/Makefile.am (TESTS): Add printf.

        * src/date.c (usage): Explain that %S's range of [0..60] is required --
        rather than 0..59 -- to accommodate the occasional positive leap second.
        Reported by Richard Neill.

2002-09-12  Jim Meyering  <jim@meyering.net>

        * src/Makefile.am (nanosec_libs): Define.
        (sleep_LDADD, tail_LDADD): Use it here.

        Factor nanosleep-related code into ../lib/xnanosleep.c.
        * src/sleep.c: Include xnanosleep.h.
        Factor out fenv.h-related code.
        (timespec_subtract): Remove function.
        (main): Remove code that deals with computing start and stop times
        as well as the loop around nanosleep.  Now that's in xnanosleep.c.

        Allow S (in --sleep-interval=S) to be a floating point value.
        * src/tail.c: Include xnanosleep.h and xstrtod.h.
        Move declaration of global variable, sleep_interval, to ...
        (main): ...here.
        (usage): Update description of --sleep-interval option.
        (tail_forever): New parameter, sleep_interval.  Update caller.
        Use xnanosleep, rather than sleep.
        (parse_options): New parameter, sleep_interval.  Update caller.
        Use xstrtod, now that we accept floating point values.
        Prompted by a patch from Augey Mikus.

2002-09-06  Jim Meyering  <jim@meyering.net>

        * src/remove.c (prompt): Change comment to give a better note to
        translators.  From Michael Piefel.

2002-09-02  Jim Meyering  <jim@meyering.net>

        * README: A good problem report/patch includes diffs against
        the most recent test release.

        * src/pathchk.c (NEED_PATHCONF_WRAPPER): Define.
        (pathconf_wrapper): Define only if NEED_PATHCONF_WRAPPER is set.

        * src/kill.c (print_table_row): Use an unsigned type for widths
        to avoid warning about comparison between signed and unsigned.
        (list_signals): Likewise.

        * src/od.c (skip): Add a cast to avoid warning about comparison
        between signed and unsigned.
        * src/install.c (get_ids): Likewise.  Also rearrange range-checking
        comparisons to make them more readable.

2002-09-01  Jim Meyering  <jim@meyering.net>

        * Version 4.5.1.

2002-08-31  Jim Meyering  <jim@meyering.net>

        Symlinks were always reported as using 0 blocks.
        * src/system.h (ST_NBLOCKS): Don't depend on file type.
        This reverts the change of 2000-01-30.
        Based on a report and patch from Neil Brown via Michael Stone.
        This fixes Debian Bug#156358.

        * Most files: Change `exit (0)' to `exit (EXIT_SUCCESS)',
        `exit (1)' to `exit (EXIT_FAILURE)', and
        `usage (1)' to `usage (EXIT_FAILURE)'.

        * chgrp.c, chmod.c, chown.c, chroot.c, cp.c, date.c, dd.c, du.c,
        * hostname.c, id.c, install.c, ln.c, mkdir.c, mkfifo.c, mknod.c,
        * nice.c, pinky.c, printf.c, pwd.c, shred.c, sleep.c, stty.c,
        * su.c, tac-pipe.c, tail.c, tee.c, touch.c, uname.c, uptime.c,
        * users.c, who.c: Change `error (1, ...' to `error (EXIT_FAILURE, ...'.
        But don't change `error (0, ...' to `error (EXIT_SUCCESS, ...', since
        error never exits successfully.

2002-08-29  Jim Meyering  <jim@meyering.net>

        * src/remove.c (remove_cwd_entries): Use closedir (not CLOSEDIR)
        when ignoring any return value.

        * src/remove.c (remove_cwd_entries): Detect and diagnose readdir
        failures.  On some systems (at least EMC Celerra and Solaris5.8),
        this appears to be necessary.
        (is_empty_dir): Likewise.  Also, always close directory handle.
        * src/ls.c (print_dir): Likewise.
        (print_dir): Rename local variable: reading -> dirp.
        Reported by Mike Coleman.

2002-08-28  Jim Meyering  <jim@meyering.net>

        * src/remove.c (remove_cwd_entries): Use CLOSEDIR, not closedir.
        Give a diagnostic and fail if closedir fails.

2002-08-26  Jim Meyering  <jim@meyering.net>

        * Makefile.am (THANKS-to-translators): New rule.
        (EXTRA_DIST): Add both THANKS-to-translators and THANKStt.in.
        * THANKStt.in: New file.

        * src/cat.c (close_stdout_wrapper): New, kludgey, function and
        file-scoped global.
        (main): Register it with atexit.
        Close STDOUT_FILENO, to avoid a problem when writing to
        /dev/audio on at least Solaris 5.7 and 5.8 systems.
        Reported by Shing-Shong Shei.

2002-08-25  Jim Meyering  <jim@meyering.net>

        * src/cat.c (main): Close STDIN_FILENO rather than a literal `0'.
        * src/tac.c (main): Likewise.

2002-08-10  Paul Eggert  <eggert@twinsun.com>

        * src/nohup.sh: Don't use "exec --"; it's not portable and
        shouldn't be needed.

2002-08-09  Jim Meyering  <jim@meyering.net>

        * src/pr.c (main): Don't ignore -COLUMN if it's the last option.
        (usage): Clarify help text for the -COLUMN option.
        Patch by Padraig Brady.
        * tests/pr/Test.pm [col-last]: New test for the above.

        * configure.ac: Start with version 4.5.1, chosen so that it's larger
        than the latest version numbers of the component packages.

        * man/Makefile.am (check-x-vs-1): Set and export PATH so we use
        programs in ../src.

2002-08-08  Jim Meyering  <jim@meyering.net>

        * src/date.c: Guard inclusion of <langinfo.h> with
        `#if HAVE_LANGINFO_CODESET', not `#if HAVE_LANGINFO_H'.
        * src/sort.c: Likewise.
        Patch by GOTO Masanori.

2002-08-05  Paul Eggert  <eggert@twinsun.com>

        Fix some minor time-related bugs with POSIX time arguments.
        Some valid time stamps were being rejected (notably -1, and
        time stamps before 1900 on 64-bit hosts).  And some invalid
        time stamps were being accepted, e.g. September 31.

        * src/date.c (main): Adjust to posixtime signature change.
        * src/touch.c (main): Likewise.  Remove unnecessary initialization.
        Use localtime, not posixtm, to warn about obsolete "touch".

2002-08-05  Jim Meyering  <jim@meyering.net>

        * tests/misc/Makefile.am (TESTS): Add nice and pathchk1.

2002-08-04  Jim Meyering  <jim@meyering.net>

        * src/Makefile.am (check-README): New target/rule.
        (check): Depend on it.

        * old/: New directory, containing legacy ChangeLog* and NEWS files
        from the fileutils, sh-utils, and textutils packages.

        * src/Makefile.am (AM_INSTALLCHECK_STD_OPTIONS_EXEMPT): Set to false.

2002-08-02  Paul Eggert  <eggert@twinsun.com>

        * NEWS, doc/coreutils.texi: uniq now obeys LC_COLLATE.

        * src/uniq.c: Include hard-locale.h, xmemcoll.h.
        (hard_LC_COLLATE): New var.
        (different): Args are now char *, not const char *.
        Use xmemcoll instead of memcmp to compare lines, so that
        LC_COLLATE has effect.  However, use memcmp if it is an
        easy locale.
        (check_file): Do not include newline in comparison, so that
        xmemcoll has a byte to stomp on temporarily.
        (main): Set hard_LC_COLLATE.

2002-07-29  Jim Meyering  <jim@meyering.net>

        * Makefile.am (SUBDIRS): Remove djgpp, for now.

2002-07-20  Jim Meyering  <jim@meyering.net>

        * Makefile.am (false.c): Convert only the final EXIT_SUCCESS
        into EXIT_FAILURE.  Otherwise, false --help and false --version
        would fail.

2002-07-08  Jim Meyering  <jim@meyering.net>

        * src/Makefile.am (uninstall-local): Search for @GNU_PACKAGE@,
        rather than the hard-coded `sh-utils'.

2002-07-01  Jim Meyering  <jim@meyering.net>

        * configure.ac: Merge the three files from fileutils,
        textutils, and sh-utils.
        * Makefile.am: Likewise.
        * src/Makefile.am: Likewise.
