        POSIX 1003.1-2001 option syntax.
        * src/sort.c: Likewise.
        From Paul Eggert.

2002-07-28  Jim Meyering  <meyering@lucent.com>

        * configure.ac: Require automake-1.6b.

2002-07-20  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.22.

        * Upgrade to cvs automake -- required to work with 2.53b.
        * configure.ac: Require automake-1.6a.

        * Upgrade to gettext-0.11.3.
        * Upgrade to autoconf-2.53b.

2002-07-02  Jim Meyering  <meyering@lucent.com>

        * src/cat.c, src/cksum.c, src/comm.c, src/csplit.c, src/cut.c (usage):
        Use the PACKAGE_BUGREPORT e-mail address, rather than hard-coding it.
        * src/expand.c, src/fmt.c, src/fold.c, src/head.c, src/join.c: Likewise.
        * src/md5sum.c, src/nl.c, src/od.c, src/paste.c, src/pr.c: Likewise.

2002-06-22  Jim Meyering  <meyering@lucent.com>

        * configure.ac: Invoke AC_GNU_SOURCE very early.

2002-06-15  Jim Meyering  <meyering@lucent.com>

        * src/cksum.c: Include <sys/types.h> before system.h.

2002-05-22  Jim Meyering  <meyering@lucent.com>

        * src/od.c [struct dummy]: Renamed.  Don't rely on portability of
        zero-length arrays.  Instead, use sizes of -1 or +1.
        Reported by Eric Backus.

2002-05-14  Jim Meyering  <meyering@lucent.com>

        `od -t f8' didn't work.
        This bug was introduced with my change of 2000-10-22 (textutils-2.0.8).
        * src/od.c (ulonglong_t): Move declaration to precede new use.
        [enum size_spec] (N_SIZE_SPECS): New member.
        (width_bytes): Add initializer corresponding to ulonglong_t type.
        (struct assert_width_bytes_matches_size_spec_decl): Declare.
        Based on a patch from Tony Kocurko.

2002-04-29  Paul Eggert  <eggert@twinsun.com>

        Use ENABLE_NLS only for gettext-related stuff, not also for
        setlocale-related stuff.  From a patch suggested by Bruno
        Haible.

        Since setlocale is now almost universal, this patch also
        removes some of the optimizations that clutter up the code and
        which don't help all that much even on hosts that lack
        setlocale.

        * lib/hard-locale.c: Upgrade to version used in GNU Diffutils 2.8.1.
        * m4/prereq.m4 (jm_PREREQ_HARD_LOCALE): Check for stdlib.h.
        Do not check for alloca.h (no longer used) or stdbool.h (was never
        used?).  Add AM_C_PROTOTYPES since hard-locale.h uses it.

        * src/sys2.h (HAVE_SETLOCALE): Define to 0 if not defined.
        * src/comm.c (compare_files): Replace #ifdef ENABLE_NLS
        with if (HAVE_SETLOCALE).
        * src/join.c (keycmp): Likewise.
        * src/sort.c (keycompare, compare): Likewise.

        * src/comm.c (hard_LC_COLLATE): Define even if ! ENABLE_NLS.
        * src/join.c (hard_LC_COLLATE): Likewise.
        * src/sort.c (hard_LC_COLLATE): Likewise.

        * src/comm.c (main): Always initialize hard_LC_COLLATE.
        Put initialization next to other locale-related stuff.
        * src/join.c (main): Likewise.
        * src/sort.c (main): Likewise.

        * src/sort.c: Include <langinfo.h> even if ! ENABLE_NLS.
        (decimal_point, th_sep): Depend on HAVE_SETLOCALE, not ENABLE_NLS.
        (main): Likewise.
        (MONTHTAB_CONST): Remove; all uses removed.
        (struct_month_cmp, inittables): Do not depend on ENABLE_NLS.
        (main): hard_LC_TIME locale does not depend on ENABLE_NLS.

2002-04-29  Jim Meyering  <meyering@lucent.com>

        * src/tail.c (parse_obsolescent_option): Do not limit the maximum
        line/byte count (when specified via obsolete option syntax) to be
        less than ULONG_MAX on systems where OFF_T_MAX is larger.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

        * src/tail.c (tail_forever): Do not treat
        max_n_unchanged_stats_between_opens specially (as if it were
        infinite) if it has its maximal value.  Similarly for
        max_n_consecutive_size_changes_between_opens.

2002-04-28  Jim Meyering  <meyering@lucent.com>

        Avoid new warnings from gcc.
        * src/pr.c [struct COLUMN] <name>: Declare member to be const.
        (init_fps): Declare local variable `firstname' to be const.

2002-04-25  Jim Meyering  <meyering@lucent.com>

        * src/wc.c (usage): Adjust ordering to match that of default output.
        Suggestion from Gaute Hvoslef Kvalnes.

        * configure.ac (AM_GNU_GETTEXT): Add external arg.
        (AC_CONFIG_FILES): Remove intl/Makefile.
        * Makefile.am (SUBDIRS): Remove intl.
        * src/Makefile.am (INCLUDES): Remove -I../intl.

2002-04-15  Jim Meyering  <meyering@lucent.com>

        * src/tr.c (usage): Give a verbose description of --squeeze-repeats,
        including the mention of SET1.  Reported by Dan Jacobson.

2002-04-12  Jim Meyering  <meyering@lucent.com>

        * src/Makefile.am (LDADD): List ../lib/libfetish.a both before
        and after @LIBINTL@.  Thanks to Paul Eggert for the fix and to
        Bruno Haible for diagnosing the problem.

2002-03-16  Jim Meyering  <meyering@lucent.com>

        * src/Makefile.am (datadir): Don't override $(datadir)
        which might be set by --datadir and different from $(prefix)/share.
        Patch from Albert Chin-A-Young.

2002-03-10  Jim Meyering  <meyering@lucent.com>

        * configure.ac (AM_INIT_AUTOMAKE): Specify the required version
        of automake (1.6), and options (gnits dist-bzip2), rather than...
        * Makefile.am (AUTOMAKE_OPTIONS): ...here.  Remove definition.

2002-03-09  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (EXTRA_DIST): Remove config/config.rpath,
        now that automake knows about it.

2002-03-05  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (EXTRA_DIST): Add config/config.rpath.

2002-02-23  Paul Eggert  <eggert@twinsun.com>

        * src/cat.c (simple_cat, cat, main): Use char * rather than
        unsigned char *, to avoid some technical violations of the C
        standard, and to avoid the need for casts.  I guess the
        unsigned char * was probably there for improved performance
        with ancient compilers, but the code wasn't using the
        unsignedness any more.
        Reported by Nelson H. F. Beebe.

        (cat): int -> size_t for full_write arg.  This doesn't
        fix any bugs since the buffer size is small, but it makes
        the code a bit clearer.

2002-02-18  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.21.

        * tests/tail/Test.pm: For tests matching /^(obs|err-[134])/,
        put _POSIX2_VERSION=199209 in the environment, so the tests succeed
        even when the environment would have contained _POSIX2_VERSION=200112.
        * tests/uniq/Test.pm (test_vector): Rename tests of obsolete usage
        to have prefix of `obs'.  Adjust environment for those tests as above.

        * tests/mk-script: When getting input via a pipe, apply the
        environment settings to the command in question, not to `cat'.
        No longer allow more than one element in the $Test::env or
        $Test::env_default arrays.  No caller used that feature.

2002-02-17  Jim Meyering  <meyering@lucent.com>

        * tests/head/Test.pm: Accept pre-POSIX 1003.1-2001 options.
        * tests/pr/Test.pm: Likewise.
        * tests/sort/Test.pm: Likewise.

        * Makefile.cfg (wget_files): Reflect new location of these files.

2002-02-16  Jim Meyering  <meyering@lucent.com>

        * ABOUT-NLS, intl/*: Update to Gettext 0.11.
        * INSTALL: Update to Autoconf 2.52h.

        * src/Makefile.am (datadir): Use `share' in place of @DATADIRNAME@,
        per Gettext-0.11.
        (LDADD): Use @LIBINTL@ instead of @INTLLIBS@, per Gettext-0.11.

        * configure.ac (AC_CONFIG_AUX_DIR): New macro invocation.
        (ALL_LINGUAS): Remove: now in po/LINGUAS as per Gettext 0.11.

        * config: New subdirectory, containing the following files from .:
        config.guess, config.sub, depcomp, missing, install-sh, mkinstalldirs.
        Move the following files here from doc: texinfo.tex, mdate-sh.

2002-02-15  Paul Eggert  <eggert@twinsun.com>

        Add support for _POSIX2_VERSION, which lets you pick which POSIX
        version you want the utilities to conform to.  Remove warnings about
        failure to conform to a future POSIX version.

        * NEWS, doc/coreutils.texi: Document _POSIX2_VERSION.
        * doc/coreutils.texi (Standards Conformance): New section.

        * src/expand.c: Include posixver.h.

        * src/head.c: Likewise.
        * src/od.c: Likewise.

        * src/od.c (short_options): Likewise.
        * src/pr.c (short_options): Likewise.
        * src/sort.c (short_options): Likewise.
        * src/split.c (shortopts): Likewise.
        * src/uniq.c (shortopts): Likewise.
        * src/unexpand.c (shortopts): Likewise.

        * src/pr.c (COMMON_SHORT_OPTIONS): Likewise.
        * src/sort.c (COMMON_SHORT_OPTIONS): Likewise.

        * src/expand.c (main): Revert to previous behavior, except report
        an error and exit if the obsolete syntax is used and if conforming
        to the new standard.
        * src/fold.c (main): Likewise.
        * src/head.c (main): Likewise.
        * src/split.c (main): Likewise.
        * src/uniq.c (main): Likewise.
        * src/tail.c (main, parse_obsolescent_option): Likewise.
        * src/unexpand.c (main): Likewise.

        * src/od.c (STRINGS_OPTION, WIDTH_OPTION): Remove; no longer needed.
        All uses changed back to the corresponding short options.
        * src/pr.c (SEP_STRING_OPTION): Likewise.

        * src/od.c (main): Parse options using POSIX 1003.1-2001 rules if
        conforming to that standard.  Do not warn of obsolete options.
        * src/pr.c (main): Likewise.
        * src/sort.c (main): Likewise.

        * src/system.h (_POSIX2_VERSION, POSIX2_VERSION): Remove definitions.
        (OPTARG_POSIX, OBSOLETE_OPTION_WARNINGS): Likewise.

2002-02-16  Jim Meyering  <meyering@lucent.com>

        * tests/misc/split-a: New test for change of 2002-02-05.
        * tests/misc/Makefile.am (TESTS): Add split-a.

2002-02-12  Jim Meyering  <meyering@lucent.com>

        * src/split.c (DEFAULT_SUFFIX_LENGTH): Define constant.
        (suffix_length): Use it here.
        (usage): Use it here.

2002-02-05  Paul Eggert  <eggert@twinsun.com>

        Change 'split' to conform to POSIX.  It now accepts an -a or
        --suffix-length option, and refuses to generate more files
        than there are suffixes.

        * NEWS, doc/coreutils.texi: Document this.
        * src/split.c: Include "dirname.h".
        (outbase): Now a global var.
        (outfile_end): Remove.
        (suffix_length): New var.
        (shortopts, longopts, main): Add -a or --suffix-length.
        (next_file_name): Implement -a.  Do not extend the suffix length.
        Check for file names that are too long.
        (main): Move outfile initialization to next_file_name.

        * src/split.c (shortopts): Remove -v (a typo).

2002-02-11  Jim Meyering  <meyering@lucent.com>

        * tests/misc/head-pos: New file/test for the change of 2002-02-08.
        * tests/misc/Makefile.am (TESTS): Add head-pos.

        * src/tr.c (unquote): Make comment a little clearer.

2002-02-08  Paul Eggert  <eggert@twinsun.com>

        * src/head.c (head_lines): If we have read too much data, try
        to seek back to the position we would have gotten to had we
        been reading one byte at a time.  POSIX currently doesn't
        require this, but it's easy to do and some software relies on it.

2002-02-02  Jim Meyering  <meyering@lucent.com>

        * src/uniq.c (main): Prepend `warning: ' to the diagnostic, so it's
        consistent with all of the other `... is obsolete...' diagnostics.

2002-01-31  Paul Eggert  <eggert@twinsun.com>

        Add more support for POSIX 1003.1-2001, which requires removal for
        support of obsolete "-N" option syntax in expand, head, fold,
        split, tail, unexpand, uniq, and which prohibits options with
        optional arguments in od and pr.

        * NEWS: Document this.
        * doc/coreutils.texi: Likewise.
        * src/expand.c (usage): Likewise.
        * src/fold.c (usage): Likewise.
        * src/head.c (usage): Likewise.
        * src/od.c (usage): Likewise.
        * src/pr.c (usage): Likewise.
        * src/split.c (usage): Likewise.
        * src/unexpand.c (usage): Likewise.
        * src/uniq.c (usage): Likewise.

        * NEWS: Improve doc for previous fix in this area.

        * src/expand.c (shortopts): New constant.
        * src/od.c (short_options): Likewise.
        * src/pr.c (short_options): Likewise.
        * src/sort.c (short_options): Likewise.
        * src/split.c (shortopts): Likewise.
        * src/unexpand.c (shortopts): Likewise.
        * src/uniq.c (shortopts): Likewise.

        * src/expand.c (main): Check for obsolete options.
        * src/fold.c (main): Likewise.
        * src/head.c (main): Likewise.
        * src/od.c (main): Likewise.
        * src/pr.c (main): Likewise.
        * src/sort.c (main): Likewise.
        * src/split.c (main): Likewise.

        * src/unexpand.c (main): Likewise.
        * src/uniq.c (main): Likewise.

        * src/head.c (header_mode_option): New constant.

        * src/od.c: New enum for long options.

        * src/pr.c (SEP_STRING_OPTION): New enum value.
        (long_options): Use it.

        * src/split.c (main): Use -1, not EOF, for getopt_long.

        * src/system.h (OPTARG_POSIX, OBSOLETE_OPTION_WARNINGS): New macros.

        * src/fold.c (main): Fix bug: -- -N was treated as -N --.

2002-02-01  Jim Meyering  <meyering@lucent.com>

        * src/tail.c (start_lines): Handle the case in which bytes_read is zero.

2002-01-28  Jim Meyering  <meyering@lucent.com>

        * Makefile.maint (ac-check): Remove, now that we no longer have
        to duplicate that information.
        (local-check): Remove ac-check.

        * Makefile.am (AUTOMAKE_OPTIONS): Require automake-1.5d.

        * configure.ac (AM_INIT_AUTOMAKE): Use zero-arg form of this macro.
        (ALL_LINGUAS): Add the bokmål dialect of Norwegian (nb).

2002-01-27  Jim Meyering  <meyering@lucent.com>

        tail -n +2 would perform an extra read after encountering EOF
        * src/tail.c (start_lines): Detect EOF, inform caller.
        (tail_lines): Upon EOF in start_lines, return immediately.

2002-01-22  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.20.

2002-01-22  Paul Eggert  <eggert@twinsun.com>

        * src/od.c (skip): Remove redundant check for overflow.
        fseeko's seek argument is already known to be in range,
        since it is less than the file size.

2002-01-22  Jim Meyering  <meyering@lucent.com>

        * po/POTFILES.in: Add lib/xmemcoll.c.

2002-01-22  Paul Eggert  <eggert@twinsun.com>

        * src/tac.c (save_stdin): Report proper errno value after
        fwrite failures.  Do not bother to rewind the temp file, as
        it'll be read backwards anyway.

2002-01-22  Paul Eggert  <eggert@twinsun.com>

        * src/ptx.c (swallow_file_in_memory): Work even if `open' returns 0.
        Check for `close' error.

2002-01-22  Paul Eggert  <eggert@twinsun.com>

        Port to glibc 2.2.5, whose mmap stdio positions the underlying
        file descriptor at a nonzero offset after an fopen.

        * m4/jm-macros.m4 (jm_MACROS): Require AC_FUNC_FSEEKO.
        * src/od.c (skip): Use fseeko rather than lseek.
        (Also, check for overflow when converting uintmax_t to off_t.)
        * src/sys2.h (EOVERFLOW, fseeko): New macros.

2001-01-21  Paul Eggert  <eggert@twinsun.com>

        * src/comm.c: Include xmemcoll.h, not memcoll.h.
        Use xmemcoll instead of memcoll.
        * src/join.c: Likewise.
        * src/sort.c: Likewise.

        * src/sort.c (die): Do not invoke cleanup; atexit does this now.
        (main): Use atexit to invoke cleanup on exit.
        Set xmemcoll_exit_failure to SORT_FAILURE.

2002-01-20  Paul Eggert  <eggert@twinsun.com>

        * src/comm.c (compare_files): Don't assume that the difference
        between two size_t values can be stored in an int; this doesn't
        work, for example, on 64-bit Solaris.
        * src/sort.c (CMP_WITH_IGNORE): Likewise.
        * src/join.c (keycmp): Likewise.  Also, fix the type of two locals
        to be size_t instead of int.

2002-01-20  Paul Eggert  <eggert@twinsun.com>

        * src/csplit.c: Don't include "xalloc.h", as system.h already
        does that via sys2.h.
        * src/sort.c: Likewise.

2002-01-19  Jim Meyering  <meyering@lucent.com>

        * configure.ac: Remove code that set LIBOBJS in support of ansi2knr.
        The latest version of autoconf objected to it, and besides, I don't
        care too much about K&R support these days.

2002-01-18  Jim Meyering  <meyering@lucent.com>

        Fix tr so it no longer gets a failed assertion for [::] or [==].

        * src/tr.c (xmemdup): Rename from `substr' and rewrite to
        take only pointer/length parameters.
        (build_spec_list): Update sole caller.
        Properly diagnose the invalid specs [::] and [==].
        Pawel Prokop reported that `tr '[::]' x' elicits a failed assertion.
        * tests/tr/Test.pm: Add tests for the above fix.

2002-01-14  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (main):  Issue a warning for obsolete usage, unless
        POSIXLY_CORRECT.
        * src/tail.c (parse_obsolescent_option): Likewise.
        * src/uniq.c (main): Likewise.

2002-01-14  Paul Eggert  <eggert@twinsun.com>

        Add support for POSIX 1003.1-2001, which requires removal for
        support of obsolete "+" option syntax in sort, tail, and uniq.

        * NEWS: Document this.

        * src/sort.c (usage, main): Implement this.
        * src/tail.c (usage, parse_obsolescent_option): Likewise.

2002-01-14  Jim Meyering  <meyering@lucent.com>

        * tests/misc/sort: New test, for just-fixed bug.
        * tests/misc/Makefile.am (TESTS): Add sort.
        (TESTS_ENVIRONMENT): Add PROG=$$tst.  This is a gross kludge
        that depends on the name of an automake-generated local variable.

2002-01-13  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (mergefps): Fix bug when eliminating empty files.
        Bug reported by James Hutt.

2002-01-13  Jim Meyering  <meyering@lucent.com>

        * tests/help-version: Tweak to work with the programs in diffutils.

2002-01-09  Jim Meyering  <meyering@lucent.com>

        * configure.in (ALL_LINGUAS): Add Turkish (tr).

2001-12-18  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (usage, specify_sort_size): Accept 'K' (which is
        now preferred, as it connotes 1024) as well as 'k'.
        * NEWS: Document this change.

2001-12-17  Jim Meyering  <meyering@lucent.com>

        * src/uniq.c (usage): Remove stray `)' in --help output.
        Reported by Padraig Brady.

        * Makefile.maint (real_dir): Remove unused variable.
        (url_dir_list): Don't set define it here, but...
        * Makefile.cfg (url_dir_list): ...define it here instead.
        (hosts, a_host, b_host): Remove now-unused variables.
        (alpha_subdir, a_url_dir, b_url_dir): Remove now-unused variables.

        the ASCII space character.

2001-12-08  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.19.

        * Makefile.cfg (wget_files): Remove ansi2knr.c, since it's
        no longer available at that location.

2001-12-03  Jim Meyering  <meyering@lucent.com>

        * src/od.c, src/tail.c, src/tr.c (usage): I will not split translatable
        strings in the middle of a sentence.  I will not split translatable
        strings in the middle of a sentence.  I will not split translatable
        strings in the middle of a sentence.  ...

        * Makefile.maint (emit-upload-commands): Fix typo: s/distdir/PACKAGE/.

2001-12-01  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.18.

        * Makefile.maint (po-check): Check for uses of _() not just in .c
        files, but also in .h files.

        Ideally, there would be just one translation for all --help
        and --version description strings.  Before this change, they
        differed only in the number of blanks between the option name
        and the description.  Someday gettext may be smart enough
        to merge such strings and to reconstruct the proper spacing at
        run time.  In the mean time, now there is one string for each,
        and those descriptions in the --help output are no longer aligned
        with the others.
        * src/sys2.h (HELP_OPTION_DESCRIPTION): New macro.
        (VERSION_OPTION_DESCRIPTION): New macro.
        * src/cat.c, src/cksum.c, src/comm.c, src/csplit.c, src/cut.c:

        * src/tail.c, src/tr.c, src/tsort.c, src/unexpand.c, src/uniq.c:
        * src/wc.c (usage): Use new macros, HELP_OPTION_DESCRIPTION and
        VERSION_OPTION_DESCRIPTION instead of hard-coding --help and
        --version descriptions.
        * po/POTFILES.in: Add src/sys2.h.

2001-11-27  Jim Meyering  <meyering@lucent.com>

        * src/system.h (SET_MODE) [O_BINARY]: Call setmode, not set_mode.
        From Matthew Smith.

2001-11-26  Jim Meyering  <meyering@lucent.com>

        * src/cat.c (cat): Don't test whether the full_write return value
        (of type size_t) is less than 0.  Reported by Nelson H. F. Beebe,
        as a warning from Irix 6.5's C compiler.

2001-11-25  Jim Meyering  <meyering@lucent.com>

        * src/cksum.c (usage): Indent --help and --version strings to
        start in the 7th column.
        * src/pr.c (usage): Likewise.

2001-11-23  Jim Meyering  <meyering@lucent.com>

        Factor out some common strings to make translation easier.

        * cat.c, cksum.c, comm.c, csplit.c, cut.c, expand.c, fmt.c, fold.c:

        * sort.c, split.c, sum.c, tac.c, tail.c, tr.c, tsort.c, unexpand.c:
        * uniq.c, wc.c: Split usage strings so that --help and --version
        descriptions are alone in their own string.
        Likewise for the one that says ``Mandatory arguments to long
        options are mandatory for short options too.''
        Suggestion from Karl Eichwalder.

        * src/ptx.c (main): Don't split copyright string in the middle
        of a sentence.

2001-11-22  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.17.

        csplit could get a failed assertion: printf 'a\n\n'|csplit - '/^$/' 2
        * src/csplit.c: No longer include assert.h.
        (process_line_count): Remove invalid assertion.  The test that caused
        the failure has been in the code since before 1992-11-08, but since
        1996 it's been in an assertion.  That assertion was disabled by default
        until textutils-1.22g (1999-01-10).  Reported by Eric Pemente.

        * tests/misc/csplit: New file.  Test for the above fix and others.
        * tests/misc/Makefile.am (TESTS): Add csplit.
        * tests/Makefile.am (EXTRA_DIST): Add lang-default.

2001-11-19  Jim Meyering  <meyering@lucent.com>

        * src/tail.c (xlseek): New function.
        Call it instead of lseek, in most cases, so any failure is reported.

2001-11-18  Jim Meyering  <meyering@lucent.com>

        * config.sub: Update from master repository.

        * src/tail.c (tail_forever): Add a cast.

        Avoid compiler warnings.
        * src/fmt.c: Remove `unsigned' attribute from type of global `prefix'.
        (copy_rest): Cast to (unsigned char *) before dereferencing.
        (get_prefix): Likewise.

        * src/tail.c (file_lines): Remove unnecessary cast.
        (tail_lines): Could have called file_lines even though the first
        lseek failed.  Fix that.

2001-11-14  Jim Meyering  <meyering@lucent.com>

        * src/tail.c (file_lines): Add a parameter, start_pos.
        Work properly even when the read pointer is not at beginning of file.
        (tail_lines): Call file_lines for any regular file, as long as lseek
        can be used to seek to its end, not just when the initial read pointer
        is at beginning of file.

2001-11-13  Jim Meyering  <meyering@lucent.com>

        * src/tail.c (tail_lines): Move declaration of local `length'
        into scope where it's used.
        (tail_file): Likewise for local `stats'.

        * tests/tail-2/Makefile.am (TESTS): Add proc-ksyms and start-middle.
        * tests/tail-2/start-middle: New test, for the bug fixed on 1995-07-24.

        `tail /proc/ksyms' would segfault on Linux.
        * src/tail.c (tail_lines): Use status of lseek (...SEEK_END) call
        in deciding whether to call file_lines or pipe_lines.
        From Herbert Xu.
        * tests/tail-2/proc-ksyms: New test, for the above fix.

        * src/join.c (make_blank): Declare to be static.
        (prfield): Declare local to be of type size_t, not int.

        Some help strings were very long.  Split them so that
        they're no longer than the magic length 509 that ISO C89
        compilers are required to support.  Sorry, translators :-(

2001-11-10  Jim Meyering  <meyering@lucent.com>

        * src/nl.c (proc_text): Use `puts' to output a string of spaces,
        not printf.  This avoids a warning from gcc's -Wformat-security.

2001-11-09  Jim Meyering  <meyering@lucent.com>

        * configure.ac: Use AC_CONFIG_FILES(...) and call AC_OUTPUT with no
        arguments.

2001-11-05  Jim Meyering  <meyering@lucent.com>

        * src/sort.c (usage): Don't recommend setting LC_COLLATE=C.

        * src/ptx.c (usage): Add one-line description.

2001-10-28  Jim Meyering  <meyering@lucent.com>

2001-10-27  Paul Eggert  <eggert@twinsun.com>

        * src/sum.c: Include human.h.
        (ROTATE_RIGHT): Remove; it was slow and the comment was
        misleading anyway.
        (bsd_sum_file): Avoid unsigned and long when they're not needed.
        Compute total input bytes as uintmax_t, not long, so that the
        code works even with files whose size does not fit in 'long'.
        (sysv_sum_file): Likewise.
        (sysv_sum_file): Do not reduce checksum until the end; this is
        what System V does.
        Reported by Nick Lawes.

2001-10-27  Jim Meyering  <meyering@lucent.com>

        Give an accurate diagnostic when `head --bytes=30M' fails.
        * src/head.c (string_to_integer): Check explicitly for overflow,

2001-09-28  Jim Meyering  <meyering@lucent.com>

        * configure.ac: Tell automake to use the file name `config.hin'
        rather than the two-`.' config.h.in.

2001-09-26  Jim Meyering  <meyering@lucent.com>

        * man/Makefile.am (common_dep): Define it, so we depend on configure.ac.

        * configure.ac: Renamed from configure.in.

2001-09-25  Jim Meyering  <meyering@lucent.com>

        * src/Makefile.am (sort_DEPENDENCIES): Remove definition altogether.
        It adds nothing to the existing: $(PROGRAMS): ../lib/libfetish.a.

2001-09-24  Paul Eggert  <eggert@twinsun.com>

        * src/Makefile.am (sort_DEPENDENCIES): Depend only on
        ../lib/libfetish.a, not on $(LDADD), since the latter may
        contain `-lintl'.  This resembles yesterday's patch for the
        `$(PROGRAMS)' rule.

2001-09-23  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.15.

        * src/Makefile.am ($(PROGRAMS)): Depend only on ../lib/libfetish.a,
        not on $(LDADD), since the former may contain `-lintl'.

        * Makefile.am (SUBDIRS): When using newer gettext (in which
        intl/libintl.h is created by rules intl/Makefile)
        `intl' must precede `lib'.

2001-09-22  Jim Meyering  <meyering@lucent.com>

        * ABOUT-NLS: Upgrade to gettext 0.10.40
        * intl: Upgrade entire directory to gettext 0.10.40
        * po/ChangeLog: New file.

        * Makefile.am (DISTCLEANFILES): Remove definition, since intl/libintl.h
        is no longer created via configure.

        * tests/od/od-N: New test for the 2001-09-19 fix by Ian Bruce.
        * tests/od/Makefile.am: New file.
        * tests/od: New directory.
        * tests/Makefile.am (SUBDIRS): Add od.
        * configure.in (AC_OUTPUT): Add tests/od/Makefile.

2001-09-19  Paul Eggert  <eggert@twinsun.com>

        * src/od.c (MAX_ADDRESS_LENGTH, pseudo_offset, format_address,
        n_bytes_to_skip, skip, format_address_none,
        format_address_std, format_address_paren,
        format_address_label, write_block, parse_old_offset, dump,
        dump_strings, main):
        Use uintmax_t, not off_t, for file addresses, so that we can
        handle multiple large files even if the sum of their sizes
        exceeds off_t limits.

        (print_s_char, print_char, print_s_short, print_short,

        print_double, print_long_double, dump_hexl_mode_trailer,
        print_named_ascii, print_ascii, decode_one_format):
        Use size_t, not off_t, for in-memory byte counts.

        (end_offset): New var.
        (dump, dump_strings): Use it.
        (main): Set it, but check for overflow while doing so.

        (skip): Report an error if an in-range lseek fails on a
        regular file, as something's seriously wrong.  Check for
        negative regular file sizes (possible with some broken NFS
        implementations).

        (parse_old_offset): Now all offsets are valid, so return a
        success boolean and take a pointer to an offset as an argument.
        All callers changed.

        (dump_strings): Check for overflow when computing end_offset -
        string_min.

        (main): Remove OFF_T_MAX checks that are no longer needed.
        Don't bother assigning through temporary when there's no size
        limit to check.

2001-09-19  Jim Meyering  <meyering@lucent.com>

        * src/od.c (open_next_file): Use SETVBUF, not setbuf.
        (skip): Revert part of last change: use lseek, not fseek.

        When --read-bytes=N (-N N) is used, disable input buffering in
        the standard I/O library.  Otherwise, od would read more input
        than requested.  This could have caused problems when reading
        from pipes, character devices, or open file descriptors inherited
        from a parent process.

        * src/od.c (open_next_file): New function, factored out of...
        (skip): Adapt to use open_next_file.
        (read_char): Likewise.
        (read_block): Likewise.
        (main): Likewise.
        (dump): Fix an off-by-one error that could have made od fail to
        report a read error when reading from a named file (not stdin).
        (check_and_close): Account for the fact that in_stream may now be NULL.
        (usage): Correct descriptions of -j and -N options.
        Patch by Ian Bruce.

2001-09-16  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (AUTOMAKE_OPTIONS): Require automake-1.5.

        * man/Makefile.am: Revamp this file, as for fileutils.

        * src/md5sum.c (digest_check): On systems for which setmode actually
        does something, arrange to read the file containing checksum strings
        in text mode.  Based on a patch from Chris Faylor.
        * src/system.h (SET_MODE): Define.

2001-09-12  Jim Meyering  <meyering@lucent.com>

        The command `echo a|./fmt -2147483647' would cause fmt to segfault.
        * src/fmt.c (fmt_paragraph): Test for sentinal directly, rather than
        doing arithmetic with it's potentially large (INT_MAX) length.
        * tests/fmt/basic: Add tests for the above.

        tail: accept new option: -F, equivalent to `--follow=name --retry',
        for compatibility with FreeBSD and NetBSD versions of tail.

        * src/tail.c (usage): Describe new option.
        (parse_options): Accept it.
        Patch by Christian Kurz, via Herbert Xu.

        The command `echo foo|fmt -w N' for N>=32K would cause fmt to segfault.

        * src/fmt.c [struct Word]: Declare members length, space, and
        line_length to be of type `int', not short.
        (MAXCOST): Define using TYPE_MAXIMUM.
        Reported by Herbert Xu.

2001-08-31  Jim Meyering  <meyering@lucent.com>

        * src/fmt.c (bool): Remove typedef, now that it's in system.h.
        (TRUE): Define to `true', not 1.
        (FALSE): Define to `false', not 0.

        * src/cat.c: Include full-write.h.
        (full_write): Remove decl; not needed.
        * src/split.c: Likewise.

        * src/cat.c (simple_cat, cat):
        Don't assume read and write size fits in int.

2001-08-28  Jim Meyering  <meyering@lucent.com>

        * src/fmt.c (main): Correct the diagnostic for invalid argument to -w.
        (main): Diagnose an invalid, old-style width option.

2001-08-27  Jim Meyering  <meyering@lucent.com>

        * Makefile.maint: Undo last change.  Instead, simply remove `N_(',
        since the `Copyright ...' line should not be translated.

2001-08-26  Jim Meyering  <meyering@lucent.com>

        * Makefile.maint (copyright-check): Update to reflect fact that
        the copyright year is now defined separately.

2001-08-08  Charles Randall <crandall@matchlogic.com>

        * src/sort.c (mergefps): Do not allocate at least sort_size
        bytes for each merge buffer.  Instead, allocate at least
        sort_size bytes total.

2001-08-25  Jim Meyering  <meyering@lucent.com>

        * tests/uniq/Test.pm: Re-enable some commented-out tests.

2001-08-25  Paul Eggert  <eggert@twinsun.com>

        * src/uniq.c (main): Fix a typo in the previous patch: missing
        a bounds check for examples like `uniq a b c'.

        * uniq.c (main): Fix some more incompatibilities with POSIX.2,
        (e.g. `uniq +3 --' did not work) by invoking getopt_long with
        leading '-', resembling what was done to 'sort' on 2001-03-20.
        Recognize an +N option only if it is an integer in range, and
        (if POSIXLY_CORRECT) only if a file name argument has not been seen;
        otherwise silently treat it as a file name.

        If the user specifies too many operands, output the first one
        in the error message, as a diagnostic aid.

2001-08-24  Paul Eggert  <eggert@twinsun.com>

        * src/uniq.c (main): Don't report an error when given the
        valid options `+3 -d'.

2001-08-24  Paul Eggert  <eggert@twinsun.com>

        * src/uniq.c (different): Don't assume that lengths can fit
        into size_t.  Tune code for the common case where the line
        lengths differ: we avoid comparing them entirely in that case.

2001-08-25  Jim Meyering  <meyering@lucent.com>

        * tests/uniq/Test.pm: Add tests for -s 0 and -w 0.

2001-08-24  Paul Eggert  <eggert@twinsun.com>

        Remove arbitrary restrictions on sizes, fixing a bug reported
        by Geoff Whale.

        * src/uniq.c (skip_fields, skip_chars, check_chars): Now size_t,
        not int.
        (size_opt): New function.  Do not arbitrarily reject size zero.
        Change the wording of the error message slightly, for convenience.
        (find_field): Use size_t, not int, to compute sizes.
        (different, main): check_chars==0 is no longer a special case, as
        it defaults to SIZE_MAX.
        (main): Check for overflow with args like -234234234234234.
        Use 'size_opt' to convert optional arguments to sizes.

2001-08-25  Jim Meyering  <meyering@lucent.com>

        * tests/uniq/Test.pm: Add new test, #54, for the just-fixed bug.

2001-08-24  Paul Eggert  <eggert@twinsun.com>

        * src/uniq.c (find_field): Don't count trailing newline to be
        part of the field.  This disagrees with POSIX.2, but it's
        gotta be a bug in the standard.  An interpretations request
        has been submitted to PASC.
        Reported by Geoff Whale.

2001-08-18  Jim Meyering  <meyering@lucent.com>

        * Makefile.maint: Merge in changes from autoconf.

        * Makefile.maint ($(v_etc_file)): Define.
        (copyright-check): Use the new variable.
        (my-distcheck): Depend on local-check so those checks are once
        again run by `make distcheck'.

        * src/head.c (head_bytes): Read no more than the specified
        number of bytes.  Patch by Ian Bruce.

        * tests/misc/head-c: New test for the above.
        * tests/misc/Makefile.am: New file.
        * tests/misc: New directory.
        * tests/Makefile.am (SUBDIRS): Add misc.
        * configure.in (AC_OUTPUT): Add tests/misc/Makefile.

2001-08-14  Jim Meyering  <meyering@lucent.com>

        * src/Makefile.am (INCLUDES): Add -I../lib so sys2.h can include
        the new, generated file, unlocked-io.h.

2001-08-13  Jim Meyering  <meyering@lucent.com>

        * src/cat.c (AUTHORS): Mark string for translation, since it
        contains the English word `and'.

        * src/cut.c: Likewise

        * src/wc.c: Likewise

2001-08-12  Jim Meyering  <meyering@lucent.com>

        * tests/mk-script ($program_name): Define.
        (main): Use $program_name, rather than long-inaccurate `build-script'.
        (main): Iterate over the sorted keys (rather than `while...each...'),
        so this script produces the same output regardless of which version
        of perl (e.g., perl5.6) is used.

2001-08-04  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (EXTRA_DIST): Add Makefile.cfg.

        * man/Makefile.am (EXTRA_DIST): Remove duplicate definition.

2001-07-08  Jim Meyering  <meyering@lucent.com>

        * src/tail.c (usage): Reformat so help2man generates a properly
        indented man page.  Patch by Herbert Xu.

2001-07-04  Jim Meyering  <meyering@lucent.com>

        * Makefile.cfg: New file with package-specific definitions.
        * Makefile.am (EXTRA_DIST): Add Makefile.cfg.

2001-07-01  Jim Meyering  <meyering@lucent.com>

        * src/sort.c (usage): Suggest setting LC_COLLATE=C, rather
        than LC_ALL=C.

2001-06-10  Jim Meyering  <meyering@lucent.com>

        * tests/sort/Test.pm: Add a test based on a report from Herbert Xu.

2001-05-20  Jim Meyering  <meyering@lucent.com>

        * src/uniq.c: Rename new option values: s/all/precede/ and
        s/minimum/separate/.
        * tests/uniq/Test.pm: Reflect the above renamings.

2001-05-12  Bruno Haible  <haible@clisp.cons.org>

        * src/tail.c (parse_obsolescent_option): Accept a b suffix.

2001-05-19  Jim Meyering  <meyering@lucent.com>

        msgmerge-0.10.37 complains about some `invalid multibyte sequences.'
        * po/el.po: Remove the offending entries.
        * po/ko.po: Likewise.
        * po/zh.po: Likewise.

2001-05-19  Jim Meyering  <meyering@lucent.com>

        Support new modes for uniq's --all-repeated option.
        The default behavior is unchanged.

        * src/uniq.c: Include argmatch.h.
        (usage): Update.
        (check_file): Implement it.
        (main): Handle new, optional arguments.
        * tests/uniq/Test.pm: New tests for the above.
        Patch by Padraig Brady.

2001-05-12  Bruno Haible  <haible@clisp.cons.org>

        * src/tail.c (parse_obsolescent_option): Use t_count_lines, not
        count_lines, in error message.

2001-05-05  Jim Meyering  <meyering@lucent.com>

        * src/comm.c (usage): Correct description of -3.
        Reported by Soeren Sonnenburg.

2001-04-22  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.14.

        * configure: Regenerate using a patched copy of autoconf-2.49e to
        work around a bug in its test for a working memcmp function.

2001-03-28  Paul Eggert  <eggert@twinsun.com>

        * src/cksum.c: Fix bugs when computing length of large files.
        Add overflow and write error checks.  Use uint_fast32_t, not
        unsigned long, to do checksum calculation, as C99 says
        uint_fast32_t should be no slower and might be faster.

        Include <stdio.h> and "system.h" even if CRCTAB is defined,
        so that the code will compile if CRCTAB is defined.
        Include "human.h" if CRCTAB is not defined.
        (uint_fast32_t): Define if it appears that stdint.h didn't.
        (BIT, remainder, main, crctab): Use uint_fast32_t, not unsigned long,
        for checksums.
        (fill_r, remainder, main): Use ANSI prototypes.
        (fill_r, remainder, main): Omit duplicate code.
        (main): Use uintmax_t, not unsigned long, for file lengths.
        Use size_t, not long, for result of fread.
        Check for overflow when computing file lengths.
        Check for write error immediately after printing a line, so that
        we don't write to stdout indefinitely after an error.

2001-04-14  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (default_sort_size): Leave a 1/16 margin for RSS.
        Suggestion from Solar Designer.

2001-04-14  Jim Meyering  <meyering@lucent.com>

        * src/wc.c (usage): Tweak --help output: s/line,/newline,/

2001-04-13  Jim Meyering  <meyering@lucent.com>

        * src/sort.c (main): Add a comment justifying the use of
        `multi-character' rather than `multibyte' in a diagnostic.
        From Paul Eggert.

2001-04-12  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (RLIMIT_AS): Do not define; just use conditional
        code, since RLIMIT_RSS is similar (and is not standardized).
        (default_sort_size): Don't allocate more than the RSS limit,
        if this host has such a limit.

2001-03-20  Paul Eggert  <eggert@twinsun.com>

        * NEWS, doc/textutils.texi: sort now accepts long options and
        checks POSIX option syntax.

        * doc/textutils.texi: Document --, -, sort long options, and
        sort -o after files.

        * src/sort.c: Include <getopt.h>.
        (usage, main): Add support for long options, and check option
        syntax as POSIX requires, though (as usual for GNU apps)
        options can follow file names unless POSIXLY_CORRECT is set.
        Many diagnostic revamped.
        (long_options): New constant.
        (badfieldspec): New arg MSGID.  Mark as noreturn.
        (parse_field_count): New arg MSGID; if null, just return null on error.
        (new_key): Renamed from key_init.  All callers changed.  Now allocates
        the new key.

2001-03-18  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.13.

        * tests/Fetish.pm: If the $DJDIR envvar is defined, set SHELL
        to $DJDIR/bin/bash.exe.  Patch from Richard Dawe, based on a
        suggestion from Eli Zaretskii.

2001-03-17  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c, src/tail.c, src/uniq.c (usage):
        Warn that the +N form will be withdrawn.
        * doc/textutils.texi: Likewise.

2001-03-08  Paul Eggert  <eggert@twinsun.com>

        * NEWS, doc/textutils.texi: Document pr changes.

        * src/pr.c: Include mbswidth.h.
        (standard_header, header, test_suite): Remove.
        (date_format, date_text, file_text, header_width_available): New vars.
        (long_options, main, init_header, usage):
        Add new -D or --date-format option.
        (CHARS_FOR_DATE_AND_PAGE, T_BUF_FMT, T_BUF_SIZE, NO_DATE): Remove.
        (init_header): Allow arbitrary width for date format.  Change
        "Page %5d" to "Page %d", since the code no longer assumes fixed width.
        Do not assume that localtime succeeds.
        (init_header, print_header, usage): Do not truncate headers.
        (init_header, print_header): Defer width calculations until
        page is printed, since "Page 100000" is wider than "Page 1".
        Count columns, not bytes, in page headers.
        Custom headers take up only the center, not the whole header.
        (print_header): Use printf rather than fprintf(stdout).

        * po/Makefile.in.in (install-data-yes): Install LC_TIME locale
        for all packages, not just for fileutils.
        (uninstall): Remove LC_TIME locale too.

        * src/sys2.h (INT_STRLEN_BOUND): New macro.

        * tests/pr/0F, tests/pr/0FF, tests/pr/2-S_f-t_notab,

2001-03-11  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (die): New message arg, to describe failures
        better.  All callers changed.

2001-03-11  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c: Decrease buffer size when only merging or checking.
        (sort_size): Now the user-specified sort size.
        (MIN_MERGE_BUFFER_SIZE): New macro.
        (MIN_SORT_SIZE): Use it.
        (merge_buffer_size): New variable.
        (fillbuf): Increase merge_buffer_size if a longer line is encountered.
        (checkfp, mergefps): Do not allocate a buffer smaller than
        merge_buffer_size.
        (sort): Use the default_sort_size if sort_size is zero.
        (main): Do not set sort_size to default_sort_size.

2001-03-06  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (sort): If all the input files are empty, create
        an empty output file.
        * tests/sort/Test.pm: Test for this.

2001-03-13  Jim Meyering  <meyering@lucent.com>

        * src/sort.c (merge): Move declarations of local variables into
        the inner scope where they're used.
        (sort): Likewise.

2001-03-06  Paul Eggert  <eggert@sic.twinsun.com>

        Avoid the need for a copy of the input file when the input and
        output overlap, e.g. 'sort F -o F'.  With -m, though, a copy
        is still needed sometimes.

        * doc/textutils.texi: 'sort F -o F' no longer needs to copy F.

        * src/sort.c: Do not include closeout.h.
        (xfopen): Use stdout if *how != 'r'.
        (mergefps): Remove FPS arg.
        Open all input files, and close all files when done.
        If OFP is null, open the output file (but after opening input files).
        All callers changed.
        (first_same_file): New function.
        (sort, merge): Remove arg OFP; we now open the output file as needed.
        All callers changed.
        (merge): New arg MAX_MERGE.  All callers changed.
        (sort): For "sort F -o F", close the input before opening the output.
        (main): Do not use close_stdout; 'sort' and 'merge' now close stdout.
        (This also fixes a close-stdout-twice bug.)
        Remove test for overlapping input and output files, as 'sort' no longer
        needs to worry about overlap, and 'merge' checks for overlap itself.
        Use first_same_file to inform 'merge' about how much to merge at
        the top level, to avoid overlap.

        `fmt --prefix=S' would not work properly for any string S containing
        a byte with the high bit set.
        * src/fmt.c (prefix): Declare to be of type unsigned char, not `char'.
        (get_prefix): Likewise for local, `p'.
        Reported by François Pinard.

        Add a test for the above-fixed problem.
        * tests/fmt: New directory/files.
        * configure.in (AC_OUTPUT): Add tests/fmt/Makefile.
        * tests/Makefile.am (SUBDIRS): Add fmt.

2001-03-05  Andreas Schwab  <schwab@suse.de>

        * src/tac.c (save_stdin): Use mkstemp to create temporary file.

2001-03-09  Jim Meyering  <meyering@lucent.com>

        * Makefile.maint (my_distdir): Define new variable, and use this
        in place of most old uses of $(distdir).

        * tests/help-version: Ensure that /dev/full is a character device
        (using test -c) as well as being writable, before trying to write to it.
        Otherwise, the test could mistakenly append a newline to an existing,
        regular, writable, /dev/full file.
        Suggested by Ulrich Drepper.

2001-03-08  Jim Meyering  <meyering@lucent.com>

        * tests/sha1sum/sample-vec: Insert the `--text' argument for each test.
        Reported by Matthew Smith.

2001-03-04  Jim Meyering  <meyering@lucent.com>

        * Makefile.maint (my_distdir): Define.
        Use it in place of $(distdir) almost everywhere.

        * Version 2.0.12.

        * Makefile.maint (alpha): Use $(PACKAGE)-$(VERSION), not $(distdir),
        since the latter now has a `$(top_distdir)/' prefix.

2001-03-01  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (die): New function.
        (create_temp_file, xfopen, xfclose, write_bytes, sort_buffer_size,
        fillbuf, main): Use it to regularize error messages.  The only change
        in behavior is that write_bytes and the final close used to say "write
        error" but now give just the output file name, which should be enough.

2001-03-01  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (xfclose): Add FILE arg, and report the file name
        on error.  All callers changed.

2001-03-01  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (main): When fclose (stdin) fails, do not mention
        the output file in the error message; mention "-" instead.

2001-02-28  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (xfopen): Set have_read_stdin to 1 only if file is "-".
        Use fopen_safer, not fopen, to avoid subtle bugs when fopen returns
        stdin, stdout, or stderr.
        (xfclose): stdout is no longer a special case.
        (main): Close output file, don't just flush it; there might be
        an error on the close.

2001-02-27  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (initbuf): If the desired size cannot be
        allocated, repeatedly halve it until allocation succeeds.
        Reported by Solar Designer.

2001-02-26  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (parse_field_count): Comment fix.

2001-02-25  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c: Tune allocation and comparison of nodes
        representing temp files.  This improved CPU performance of
        'sort -S 1 *.[ch]' by 17% on my host.

        (struct tempnode): name member now uses struct hack.
        (temphead): Now a pointer, not a structure.  All uses changed.
        (create_temp_file): Allocate node using struct hack.
        (zaptemp): Free node using struct hack.  Use pointer comparison, not
        string comparison.

2001-02-25  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (eolchar, trim_trailing_blanks): Now static.

2001-02-25  Paul Eggert  <eggert@twinsun.com>

        'sort' race condition fixes.

        Defend against a DoS attack where someone else creates a
        temporary file with the same name as ours.  Use mkstemp to do
        this, supplying our own mkstemp if the system doesn't have one.

        Also, fix a race condition during cleanup on hosts without
        sigaction.

        * src/sort.c (NAME_MAX_IN_DIR): Remove.
        (sigprocmask, sigset_t): New macros, defined only on older hosts.
        (caught_signals): New var.
        (xtmpfopen, tempname): Removed.
        (create_temp_file): New function, combining the functions of the old
        xtmpfopen and tempname.  All callers changed.
        Use mkstemp to create the file.
        (sighandler): On hosts without sigaction, ignore signals while
        cleaning up, instead of letting them interrupt cleanup.
        (main): Initialize caught_signals.  On hosts with sigaction, block all
        caught signals while handling one.  Remove duplicate code.

2001-02-22  Jim Meyering  <meyering@lucent.com>

        * src/sort.c (keycompare): Move declarations of locals, lena and lenb,
        into the inner scope where they are used.

2001-02-19  Jim Meyering  <meyering@lucent.com>

        * src/sort.c (AUTHORS): Add Paul Eggert.

        * src/wc.c (wc): Rename innermost `buf' to avoid shadowing warning.
        (wc): Rename local `wc' to avoid shadowing function name.

2001-02-18  Paul Eggert  <eggert@twinsun.com>

        Fix a race condition: freed storage accessed during a signal handler.

        * src/sort.c (struct tempnode.next): Now volatile.
        (zaptemp): Free the file name after removing it from the temp list,
        not before, because a signal can arrive between the two actions
        and cleanup () traverses the list.

2001-02-18  Paul Eggert  <eggert@twinsun.com>

        Check for input size, and do not overallocate memory.
        Also check for memory quotas.

        Revamp storage management so that line tables and character data are
        taken from the same buffer.  Line tables are now in reverse order,
        since they grow down while the character data grow up.

        * src/sort.c:
        (<sys/resource.h>): Include if HAVE_SYS_RESOURCE_H.
        (struct rlimit, getrlimit): Define a replacement if RLIMIT_DATA
        is not defined.
        (RLIMIT_AS): Define to RLIMIT_DATA if not defined.
        (struct lines): Remove.
        (struct buffer): New members nlines, line_bytes, eof.
        Remove member newline_free; no longer needed, since the code no longer
        runs out of line table space.
        (SORTALLOC_MIN, SORTALLOC_DEFAULT_MIN): Remove.
        (sort_size): Renamed from sortalloc; now applies to the sum of the
        character data and the line table, not just the character data.
        (MIN_SORT_SIZE, INPUT_FILE_SIZE_GUESS): New macros.
        (linelength): remove.
        (specify_sort_size): Don't worry about the distinction between the
        character data and the line table; that is now the caller's
        responsibility.
        (default_sort_size): Return the value, instead of being executed for
        side effect.  Return half of available memory, or 1/16 of total memory,
        whichever is greater; except do not exceed 1/2 of quota.
        (sort_buffer_size): New function.
        (initbuf): New arg LINE_BYTES.  Ensure that the line array is properly
        aligned.  Initialize the new set of struct buffer members.
        (buffer_linelim): New function.
        (fillbuf): Return int, not size_t, since the callers merely care
        whether the result is nonzero.  New arg FILE so that error messages
        can report the file name.  Keep track of eof.  Initialize the line
        table too, taking its memory from the input buffer's memory; this
        subsumes the old findlines function and removes the need for worrying
        about running out of line table entries.
        (checkfp, mergefps, sortlines, merge, sort): Adjust to the new storage
        management regime, in particular the fact that line tables are now
        filled in by fillbuf and are in reverse order.
        (checkfp): Now takes char *, not const char *, since subroutines
        require that now.  Rewrite to avoid lint and duplicate code.
        If line length alloc calculation overflows,
        simply allocate enough memory to hold the line.
        (mergefps): New arg FILES, used for buffer size calculation and error
        messages.  Rewrite to avoid lint.  Do not loop if savealloc*2
        overflows.
        (mergefps, merge): Zap temporary files eagerly rather than lazily;
        this is needed because we now pass FILES to mergefps.
        (sortlines): Args now point at end of arrays, not at beginnings.
        (sort): Do not allocate temporary line array for sortlines;
        instead, take the space from the same buffer.
        (main): Adjust to sort_size and default_sort_size changes.

        LONGEST_INTEGRAL_TYPE.
        (print_long_long): Compile this function even on systems without
        long long support.
        (decode_one_format): Remove #if directive.

        * src/od.c (decode_one_format): Guard use of print_long_long with
        `#if HAVE_UNSIGNED_LONG_LONG'.  From Darren Salt.
        Change all `#ifdef HAVE_UNSIGNED_LONG_LONG' to use `#if' instead.

2000-12-23  Jim Meyering  <meyering@lucent.com>

        * src/sys2.h [HAVE_INTTYPES_H]: Include <inttypes.h>.

2000-12-19  Jim Meyering  <meyering@lucent.com>

        * Version 2.0.11.

2000-12-18  Paul Eggert  <eggert@twinsun.com>

        * NEWS, doc/textutils.texi: New "sort" option -S SIZE.

        * src/sys2.h (UINTMAX_MAX): New macro, taken from C99.

        (initlines): Do not let alloc exceed limit.
        (findlines): Likewise.
        (checkfp, mergefps, sort): Use sortalloc to size everything
        else, instead of relying on precomputed sizes.

2000-12-17  Jim Meyering  <meyering@lucent.com>

        (flag_pseudo_start): Now int, not long int.
        (pseudo_offset): Now off_t, not long int.
        (n_specs, n_specs_allocated): Now size_t, not unsigned int.
        (format_address, format_address_none, format_address_std,
        format_address_label): Now accepts an extra char argument (an extra
        char to print if nonzero), and prints instead of returning a string.
        All callers changed.
        (bytes_per_block): Now size_t, not int.
        (format_address_none): Do not even print the extra char argument.
        This simplifies the callers.
        (format_address_std, format_address_label): Print off_t ourself
        instead of trying to use autoconfigured format.  This is faster and
        more portable.
        (format_address_paren): New function.
        (dump): Remove unnecessary cast.
        (expand_address_fmt): Remove.
        (main): Use size_t, off_t, etc. instead of builtin types where this is
        advisable.  Adjust to above changes.  Remove unnecessary cast.

2000-12-03  Jim Meyering  <meyering@lucent.com>

        * src/tail.c (tail_file): Initialize ignore, dev, and ino members,
        when tailing forever and the open failed.  Otherwise, we could get
        uninitialized memory references of those fields in recheck.
        * tests/tail-2/Makefile.am (TESTS): Add assert-2.
        * tests/tail-2/assert-2: New file.

        * Version 2.0.9.

        Make od print valid addresses for offsets of 2^32 and larger, and
        allow byte offset (-j) and byte count (-N) to be 2^32 and larger.

        * src/od.c (MAX_ADDRESS_LENGTH): Don't hard-code as a literal.

        Fail if the specified offset if larger than OFF_T_MAX.
        (dump_strings): Declare local `i' to be of type size_t.
        Remove the now-unnecessary cast-to-off_t.
        (main) [IF_LINT]: Initialize desired_width to avoid a warning.
        Declare `tmp' to be of type uintmax_t.
        Use xstrtoumax, not xstrtoul.
        Fail if minimum string length is larger than SIZE_MAX.
        Fail if specified width is larger than ULONG_MAX.

        * src/od.c (format_address): Use off_t, not long unsigned_int as the
        parameter type.
        (format_address_none): Likewise.  Mark parameter as unused.
        (format_address_std): Likewise.
        (format_address_label): Likewise.
        (print_ascii): Mark format string parameter as unused.
        (write_block): Use off_t, not long unsigned_int as offset type.
        (expand_address_fmt): New function.
        (main): Use it to expand each address format string template.
        Reported by Mark Nudelman, via Andreas Jaeger.

        * src/sys2.h (OFF_T_MIN): Define here instead.
        (OFF_T_MAX): Likewise.
        (CHAR_BIT): Define.

        * src/tail.c (parse_options): Use xstrtoumax to parse the byte and line
        offset.  Give a better diagnostic when the requested offset is still
        representable but larger than OFF_T_MAX.
        (OFF_T_MIN): Remove definition.
        (OFF_T_MAX): Likewise.

2000-12-02  Jim Meyering  <meyering@lucent.com>

        bit more readable.

        * doc/textutils.texi (sort invocation): Clarify how -t works

2000-11-26  Paul Eggert  <eggert@twinsun.com>

        * src/od.c (skip): Use lseek instead of worrying about fseeko or fseek.
        This should be portable, as we seek before doing any I/O.
        (fseeko): Remove; no longer used.

2000-11-30  Jim Meyering  <meyering@lucent.com>

        * src/sort.c: s/SIZE_T_MAX/SIZE_MAX/.

2000-11-29  Paul Eggert  <eggert@twinsun.com>

        Port GNU "sort" to hosts where sizes don't fit in "int",
        e.g. 64-bit Solaris (sparc).

        * src/sort.c ("human.h", "xstrtol.h"): Include.
        (struct line): length member is now size_t, not int.
        (struct lines): Likewise for used, alloc, limit members.
        (struct buffer): Likewise for used, alloc, left, newline_free members.
        (struct keyfield): Likewise for sword, schar, eword, echar members.
        (sortalloc, mergealloc, linelength): Now size_t, not int.

        (initbuf, fillbuf, initlines, begfield, limfield, findlines,
        numcompare, getmonth, keycompare, compare, checkfp, mergefps,
        sortlines, sort): Accept, return, and use size_t for sizes, not int.

        (fillbuf, initlines, findlines, checkfp, sort): Check for overflow
        when computing buffer sizes.

        (begfield, limfield): Do not index past end of array.

        (checkfp): Return a boolean, not a line number, as the line
        number may not fit in int.  All callers changed.  Use
        uintmax_t for line numbers, not int.

        (sort): Don't allocate tmp until we need it (and know the right size).

        (parse_field_count): New function.

        (main): Use it to check for overflow in field counts.
        "outfile" is now a pointer to const.

2000-11-27  Jim Meyering  <meyering@lucent.com>

        * src/checksum.h: Don't include system.h here.

        non-option.

2000-11-18  Jim Meyering  <meyering@lucent.com>

        * doc/textutils.texi: Change GNU to @sc{gnu} in many places.
        Update to use the Free Documentation Licence.

        * configure, config.h.in, Makefile.in, etc.: Regenerate using the
        very latest version (in CVS) of autoconf.

2000-11-17  Jim Meyering  <meyering@lucent.com>

        * GNUmakefile (.NOTPARALLEL): New target.  Prevent unwanted parallelism.
        Suggestion from Ulrich Drepper.

2000-11-16  John David Anglin  <dave@hiauly1.hia.nrc.ca>

        * src/join.c: Declare global `tab' to be of type *unsigned* char,
        so join works with 8-bit delimiter characters.
        Reported by Antonio Rendas.
        * tests/join/Test.pm (8-bit-t): New test for the above fix.

2000-11-13  Paul Eggert  <eggert@twinsun.com>

2000-10-21  Jim Meyering  <meyering@lucent.com>

        * src/cat.c (LINE_COUNTER_BUF_LEN): Define to allow numbering as
        many as 10^18 - 1 lines (the old limit was 10^11 - 1, and could
        be exceeded without too much trouble).  Use this symbol rather
        than hard-coding the constant everywhere.
        (next_line_num): Rather than overrunning for input with more lines,
        mark the line number by putting a `>' in the leftmost slot.
        Patch by Jan Nieuwenhuizen.

        * src/sort.c (SORT_OUT_OF_ORDER): Define.

2000-08-19  Jim Meyering  <meyering@lucent.com>

        * src/comm.c (writeline): Correct comments.  From Bruno Haible.

2000-08-11  Paul Eggert  <eggert@twinsun.com>

        * doc/textutils.texi:

        Portable shell scripts should specify global options before
        key fields.

        Move global LC_CTYPE remark to each sort option that depends
        on LC_CTYPE.

        sort -g depends on LC_NUMERIC.

        Add @vindex where it's missing.

        "radix character" -> "decimal-point character", to match Standard C
        terminology, which is easier for most people to follow.

        "comm" does not consider trailing newlines to be significant.

2000-08-10  Paul Eggert  <eggert@twinsun.com>

        * doc/textutils.texi: Recommend against the System V syntax
        for tr ranges, and don't use it in examples.  Use POSIX
        classes rather than ranges, for portability.
        * src/tr.c (usage): Don't describe System V syntax, as it
        doesn't always work.

        * src/sort.c (usage): Describe -d and -i in a locale-independent way.

        * doc/Makefile.am (constants.texi): Use the C locale so that
        [A-Z] works as expected.

2000-08-07  Paul Eggert  <eggert@twinsun.com>

        * src/cut.c (cut_fields): Invoke xalloc_die instead of printing

        (wc): New variables `bytes', `count_bytes', `count_chars',
        `count_complicated'. The old code determines `bytes', not `chars'.
        New case for MB_CUR_MAX > 1. A non-printable non-space character does
        not increment the line position or start a word. Update `total_bytes'.
        (main): Initialize `print_bytes' and `total_bytes' to 0. Accept 'm'
        option. Pass `total_bytes' to write_counts.
        * doc/textutils.texi (wc invocation): Update accordingly.

        * Version 2.0g.

2000-08-04  Jim Meyering  <meyering@lucent.com>

        * src/sort.c (main): Rename local `t' to `tmp_dir' to avoid shadowing
        a previous local by that name.
        (usage): Warn that GNU sort is now locale-aware, and suggest
        people put LC_ALL=POSIX in their environment.

        * src/pr.c (store_columns): Remove conjunct that would dereference
        an out-of-bounds pointer.  Reported by Greg McGary (who found this
        bug using his bounded-pointers-enabled gcc).

        building on a suggestion by Charles Randall.

        * src/sort.c (fillbuf): Skip memmove if it would be a no-op,
        as many memmove implementations are slow in that case.
        Don't examine leftover bytes for eolchar, since they may be left
        over from a previous file, and we want to read from this file.

        (sort): At end of file, if there is more input and buffer room,
        concatenate the next input file.

2000-02-29  Jim Meyering  <meyering@lucent.com>

        `make alpha' time.
        (writable-files): New target.
        (my-distcheck): Depend on it.
        (alpha): Likewise.

        * po/POTFILES.in: Add these: lib/makepath.c, lib/rpmatch.c,
        and lib/same.c

2000-01-29  Jim Meyering  <meyering@lucent.com>

        * configure.in: Remove lib-check for cposix now that we use
        m4/isc-posix.m4.
        (jm_LIB_CHECK): Use this even though the library checks aren't
        required for this patchage (so all three lib/Makefile.in files
        will be the same).

2000-01-24  Mark Kettenis  <kettenis@gnu.org>

        * src/tsort.c (exit_status): New variable.
        (loop): New varibale.
        (count_items, scan_zeroes): Change return type to int.
        (detect_loop): Complete rewrite to correctly implement detection
        of loops.  Also change return type to int.
        (recurse_tree): Stop if ACTION returns non-zero.  This involves
        changing the return type of this function and ACTION to int.
        (walk_tree): Change return type of ACTION to int.
        (tsort): Continue sort after a loop has been detected (and
        broken).  Set exit_status to 1 if a loop was detected.
        (main): Use exit_status to determine exit code.
        * tests/tsort/basic-1: Change expected output for cycle-1 and
        cycle-2 tests.

2000-01-23  Jim Meyering  <meyering@lucent.com>

        * configure.in (AM_FUNC_STRTOD): Move to m4/.
        (AC_SUBST(POW_LIBM)): Likewise.

2000-01-22  Jim Meyering  <meyering@lucent.com>

        * src/sort.c (keycompare): Use global, hard_LC_COLLATE in place of
        local that is sometimes undeclared.

        * configure.in (ALL_LINGUAS): Add Brazilian Portuguese (pt_BR).
        (AC_CHECK_HEADERS): Move these checks into m4/.

        * src/tr.c ("xstrtol.h"): Include.
        (Filter): Rename from PFL.
        (non_neg_strtol): Remove function.
        (find_bracketed_repeat): Use xstrtoul instead of non_neg_strtol.
        (squeeze_filter, set_initialize, main): Use size_t and ssize_t in
        place of long and int in several decls.
        (read_and_delete, read_and_xlate): Likewise, and remove assertion.
        * tests/tr/Test.pm (o-rep-1, o-rep-2): New tests.

        * src/cut.c: Correct copying notice to use GPL, per author's request.
        * src/paste.c: Likewise.
        (AUTHORS): Add djm.

1999-09-19  Bruno Haible  <haible@clisp.cons.org>

        * src/tr.c (PFI): Return `long', not `int'.
        (PFL): Rename from PFI now that it returns long.
        (squeeze_filter): Declare as `long': i, nr, out_len.

2000-01-17  Paul Eggert  <eggert@twinsun.com>

        Tweak sort performance.

        * src/sort.c (hard_LC_CTYPE): Remove.
        (keylist): Renamed from keyhead.  Now a pointer, not a
        mostly-unused struct.  All uses changed.
        (findlines, keycompare, CMP_WITH_IGNORE, compare, checkfp, mergefps,
        sort): Tune and use a more consistent style for reallocation.
        (keycompare, main): Don't worry about LC_CTYPE;
        it's buggy with multibyte chars anyway.
        (compare): Invoke alloca (0) after each call to keycompare,
        not just the ones that return nonzero.  This avoids a memory
        leak on architectures without builtin alloca that occurs
        sometimes when a file contains all duplicate lines.

2000-01-17  Paul Eggert  <eggert@twinsun.com>

        * src/csplit.c (interrupt_handler, main):
        Don't use SA_INTERRUPT to decide whether to call sigaction, as
        POSIX.1 doesn't require SA_INTERRUPT and some systems
        (e.g. Solaris 7) don't define it.  Use SA_NOCLDSTOP instead;
        it's been part of POSIX.1 since day 1 (in 1988).
        * src/sort.c (sighandler, main): Likewise.

2000-01-16  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am: Merge with fileutils/lib/Makefile.am.

        * configure.in: Remove AM_FUNC_ERROR_AT_LINE, jm_FUNC_STRFTIME,
        AC_FUNC_VPRINTF, and AC_FUNC_ALLOCA.  Now they're in m4/.

2000-01-15  Jim Meyering  <meyering@lucent.com>

        * configure.in (AC_REPLACE_FUNCS): Remove these: memcpy memset stpcpy
        strpbrk strtol strtoul.  Now that's in m4/.

        unexpand could infloop
        * src/unexpand.c (TAB_STOP_SENTINEL): Define.
        (unexpand): Use it instead of INT_MAX.
        Declare column and pending to be `unsigned'.
        Increment pending and column counters only if column is smaller
        than TAB_STOP_SENTINEL.
        * tests/Makefile.am (SUBDIRS): Add unexpand.
        * tests/unexpand/basic-1: New tests for the above-fixed bug.
        * configure.in (AC_OUTPUT): Add tests/unexpand/Makefile.
        Reported by John Kodis.

2000-01-12  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (fillbuf): Avoid quadratic behavior with long lines.
        Also, stop worrying about ancient memchr bug (misbehavior when
        size is zero), since other code doesn't worry either.

2000-01-11  Jim Meyering  <meyering@lucent.com>

        Sync lib/ directories of sh-utils, and textutils.

        * lib/Makefile.am (libfetish_a_SOURCES): Add getdate.y, posixtm.c,

        xgethostname.c.
        (noinst_HEADERS): Add getdate.h, group-member.h, posixtm.h,
        pathmax.h, readutmp.h

        More nits.
        * src/cut.c (OUTPUT_DELIMITER_OPTION): Define this and use it
        instead of `CHAR_MAX + n'.
        * src/pr.c (PAGES_OPTION, COLUMNS_OPTION): Likewise.

2000-01-07  Jim Meyering  <meyering@ascend.com>

        * tests/tsort/Makefile.am (TESTS_ENVIRONMENT): Add `pwd`/ prefix
        to exported PATH value (though not strictly necessary, here).
        * tests/md5sum/Makefile.am: Likewise.

        Nits.
        * lib/memcasecmp.c: Use `#if' instead of `#ifdef' for `HAVE_CONFIG_H'.
        Capitalize all macro parameters.
        (memcasecmp): Ansideclify.
        Don't cast away `const'ness of parameters.
        * lib/strpbrk.c (strpbrk): Ansideclify.
        Use `#if' instead of `#ifdef' for `HAVE_CONFIG_H'.
        Suggestions from François Pinard.

2000-01-06  Jim Meyering  <meyering@ascend.com>

        * tests/tail-2/assert: Tell the user just before sleeping for 7 seconds.

        * tests/tail-2/Makefile.am (TESTS): Remove fflush test.  It didn't
        test the losing behavior, and left a stray tail process to boot.

2000-01-01  Jim Meyering  <meyering@ascend.com>

        * Version 2.0a.

        * lib/Makefile.am (lstat.c): Adapt rule to handle new parts of xstat.in.

        * src/system.h: Move them from here...
        * src/sys2.h: ... to here.

1999-12-09  Jim Meyering  <meyering@ascend.com>

        * configure.in (ALL_LINGUAS): Add Galician (gl).

        * tests/tail-2/Makefile.am (TESTS): Add fflush.

1999-10-26  Marc Boucher  <marc@mbsi.ca>

        * src/tail.c (main): Flush stdout before switching to unbuffered mode
        and calling tail_forever.  Required only on Solaris2.7 -- on other
        systems, using setvbuf to switch to unbufferd mode does the flush.

1999-11-22  Jim Meyering  <meyering@ascend.com>

        * lib/Makefile.am (DISTCLEANFILES): Put $(BUILT_SOURCES) here rather
        than in $(MAINTAINERCLEANFILES).

        * src/tail.c (recheck): Handle a race condition (including <dev,inode>
        reuse) that would lead to a failed assertion.
        Reported by Ken Pizzini.
        (tail_forever): Record errno before using it in call to `error'

1999-11-05  Jim Meyering  <meyering@ascend.com>

        * src/system.h: Use HAVE_STRUCT_STAT_ST_BLKSIZE not HAVE_ST_BLKSIZE.

        * configure.in: Move some type/header/member tests into
        m4/jm-macros.m4 (jm_CHECK_ALL_TYPES) so they are shared by all of
        fileutils, textutils, and sh-utils.

1999-11-04  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (SORTALLOC): New macro.
        (sortalloc, mergealloc, LINEALLOC): Use it.
        (sortalloc, mergealloc, linelength): Now const.
        (sortalloc): Increase from 0.5 to 8 MB.
        (mergealloc): Increase from 16 to 256 kB.
        (LINEALLOC): Increase from 0.25 to 4 MB.

1999-11-03  Paul Eggert  <eggert@twinsun.com>

        * NEWS, doc/textutils.texi:
        Do not consider newline to be part of a line when comparing lines
        in `sort' and `comm'.  POSIX.2 requires that we consider newline,
        but this is a bug in the spec and the bug will likely be fixed.
        * src/comm.c (compare_files): Likewise.
        * src/sort.c (begfield, limfield, findlines, keycompare, compare):
        Likewise.
        * tests/sort/Test.pm:  Update tests `use-nl' and `11d' to reflect
        this change.

        * lib/linebuffer.c (readline): Do not leave room for an extra
        byte after the newline; it's no longer needed.
        * src/sort.c (sortalloc, mergealloc, fillbuf, checkfp, mergefps):
        Likewise.

        * lib/memcoll.c (memcoll): The two arguments cannot be
        adjacent any more, so remove the alloca/copy workaround for
        that case.

1999-11-03  Jim Meyering  <meyering@ascend.com>

        Fix so that `tail -fn 2 file' works again.
        * src/tail.c (anonymous enum) [LONG_FOLLOW_OPTION]: Define.
        (long_options): Use LONG_FOLLOW_OPTION here, instead of 'f'.
        (main): Remove the `::' after the `f' in getopt_long string.
        Add `case LONG_FOLLOW_OPTION' after `case 'f':'.
        Based on a patch from Tim Waugh.

        * man/Makefile.summ (cat-summary): Remove now-unused file.
        * man/Makefile.am (EXTRA_DIST): Remove Makefile.summ.
        * man/Makefile.maint: Include Makefile.summ with leading `-'.
        This file is shared by fileutils and sh-utils, both of which still
        have the file (albeit nearly empty now).
        Suggestion for clean-up from Akim Demaille.

1999-11-01  Jim Meyering  <meyering@ascend.com>

        * lib/Makefile.am (MAINTAINERCLEANFILES): Set to $(BUILT_SOURCES).

        * tests/tsort/Test.pm: Remove.

        * man/help2man: Escape backslashes so tr's manual comes out right.
        Reported by Andreas Schwab.

        * src/tsort.c (usage): Correct address for bug reports.

        --count, -repeated, --all-repeated, --unique.
        Based on a patch from Ian Turner.

1999-08-15  Jim Meyering  <meyering@ascend.com>

        * src/tail.c (ENOSYS): Define to a bogus value if not already defined.

1999-08-13  Eli Zaretskii  <eliz@is.elta.co.il>

        * src/tail.c (parse_options): Warn if --pid=PID is used and kill()

        * Version 1.22q.

        * configure.in: Remove inadequate getline-testing code.  md5sum would
        segfault on HPUX because of the getline function in their C library.
        Use the AM_FUNC_GETLINE test in m4/ instead.

1999-08-03  Jim Meyering  <meyering@ascend.com>

        * src/tail.c (tail_forever): When following by name and calling recheck
        because of exceeding max_n_consecutive_size_changes_between_opens,
        `continue' so we don't fall through and (assuming the file finally grew)
        get the erroneous `file truncated' message.  This was hard to reproduce.

1999-08-01  Jim Meyering  <meyering@ascend.com>

        * Version 1.22p.

        * configure.in (AM_C_PROTOTYPES): Move test to precede a few

        Don't quote spaces if C quoting style.

1999-07-31  Jim Meyering  <meyering@ascend.com>

        * src/tail.c (tail_forever): Don't call kill if pid is 0.

        From Karl Heuer.

        * src/tail.c (parse_options): Warn if --pid=PID is used without -f.

1999-07-30  Jim Meyering  <meyering@ascend.com>

        * Version 1.22o.

        * src/tail.c: New option: --pid=PID.
        Include signal.h for kill prototype.
        (pid): New global.
        (long_options): Add `pid'.
        (usage): Describe it.
        (tail_forever): Implement it.
        (parse_options): Handle the new option and required arg.
        Suggestion and pseudo-code from Karl Heuer.

1999-07-27  Jim Meyering  <meyering@ascend.com>

        * lib/linebuffer.c: Include <sys/types.h> now that linebuffer.h uses
        size_t.  This is required on at least SunOS4.  From Kaveh Ghazi.

1999-07-26  Jim Meyering  <meyering@ascend.com>

        * src/sys2.h (PID_T_MAX): Define.

        * src/tail.c (struct File_spec) [n_stat_calls]: Remove unused member.

1999-07-25  Jim Meyering  <meyering@ascend.com>

        * src/pr.c (usage): Remove `NEWS'-style paragraph (sorry to have
        let that in, translators).

        * Version 1.22n.

1999-06-01  Volker Borchert  <bt@teknon.de>

        * tests/Makefile.am: Make envvar-check depend on check-recursive rather
        than on `check' so that its tests are performed before any real tests.

1999-07-20  Jim Meyering  <meyering@ascend.com>

        * configure.in (AC_REPLACE_FUNCS) Remove memmove, now that it's
        AC_REPLACE...'d in m4/jm-macros.m4.

        * src/wc.c (posixly_correct): Declare global.
        (write_counts): Use it to select printf formats.

        From Peter Moulder.

1999-07-15  Jim Meyering  <meyering@ascend.com>

        * tests/md5sum/Makefile.am: Revert the 1999-02-15 change.
        * tests/md5sum/basic-1, newine-1: Add --text for each individual test.
        Reported by Eli Zaretskii.

1999-07-12  Jim Meyering  <meyering@ascend.com>

        * configure.in (ALL_LINGUAS): Add Slovak (sk).

1999-07-11  Jim Meyering  <meyering@ascend.com>

        * src/tail.c (recheck): Use assert instead of unnecessary close_fd.

1999-07-10  Jim Meyering  <meyering@ascend.com>

        * doc/textutils.texi: Document new tail options.

        * src/tail.c (struct File_spec) [tailable]: Rename from `missing' and
        document.  Change all uses and locals like was_missing to was_tailable.
        Invert expressions as appropriate.
        (reopen_inaccessible_files): Rename from allow_missing.
        (sleep_interval): Describe.
        (--allow-missing): Deprecate.
        (--retry): New option, equivalent to --allow-missing.
        (usage): Document name vs. descriptor differences.
        Refer to manual for descriptions of --max-unchanged-stats=N
        and --max-consecutive-size-changes=N.
        (valid_file_spec): New function.
        (recheck): Assert valid_file_spec.
        Remove dead else-if block (suggestion from Eli Zaretskii).
        Adjust stmts that set f->tailable -- unlike for `missing', tailable
        doesn't depend on errno == ENOENT.
        (parse_options): Give a warning if --retry is used when not following
        by name.

        * tests/join/Test.pm: New test case (but commented out) for
        Paul's 1999-06-01 fix.

1999-07-09  Jim Meyering  <meyering@ascend.com>

        * src/tail.c (struct File_spec): New member, errnum.
        (recheck): Record the new value of errno in f->errnum.  Don't
        output an error message unless the new value of errno differs from
        the old one.  Output a message if previously-inaccessible file
        becomes accessible.
        (tail_forever): Always recheck files whose fd is negative.  If the
        file cannot be fstat'ed, record the errno value in f[i].errnum.
        (tail_file): If the file cannot be open, record the errno value in
        f->errnum.  If it can be opened, initialize f->errnum to zero.  If
        it's a non-regular non-fifo file, initialize f->errnum to -1.

1999-06-21  Jim Meyering  <meyering@ascend.com>

        * doc/textutils.texi: Use lower case characters in sc{} context.
        Reported by Eli Zaretskii.

1999-06-03  Paul Eggert  <eggert@shade.twinsun.com>

        * src/join.c (xfields): Only <blank>s separate fields, not <space>s.

1999-06-01  Paul Eggert  <eggert@twinsun.com>

        * lib/linebuffer.c (readline): Leave room for an extra byte
        after the newline; comm needs this for memcoll.

1999-06-01  Paul Eggert  <eggert@twinsun.com>

        Add LC_COLLATE support to `join'.

        * doc/textutils.texi: Describe join and LC_COLLATE.

        * src/join.c: Add support for LC_COLLATE locale.
        Include hard-locale.h, linebuffer.h, memcoll.h.
        (struct line): New member `buf', replacing `beg' and `lim'.
        All uses changed.
        (hard_LC_COLLATE): New var.
        (main): Initialize it.
        (get_line): Use readline to read the line,
        instead of doing it by hand.
        That way, we get a buffer that we can pass to memcoll.
        (keycmp): Use memcoll to compare lines if hard_LC_COLLATE is nonzero.

1999-05-27  Volker Borchert  <bt@teknon.de>

        * tests/Makefile.am: Qualify .env-warn with $(srcdir)/ prefix.

1999-05-25  Paul Eggert  <eggert@twinsun.com>

        Add LC_COLLATE support to `comm', so that `comm' is compatible
        with `sort' in nontrivial locales.

        * doc/textutils.texi: Document locale-specific mode for comm.

        * lib/Makefile.am (libtu_a_SOURCES): Add hard-locale.c, memcoll.c.

        (main): Initialize hard_LC_COLLATE from locale.

        * src/sort.c: Include hard-locale.h, memcoll.h.
        (hard_LC_COLLATE, hard_LC_CTYPE, hard_LC_TIME): New variables,
        replacing `need_locale'.
        (memcoll): Move to lib/memcoll.c.
        (keycompare): No need to alloc (0), since our caller now does it.
        (compare): alloca (0) before returning.
        (my_setlocale): Remove; hard_locale now dows this.
        (main): Invoke setlocale, bindtextdomain, and textdomain before
        invoking anything that might print an error.
        Use hard_locale to determine which locales are hard.

        * lib/hard-locale.c, lib/hard-locale.h, lib/memcoll.c, lib/memcoll.h:
        New files.

1999-05-25  Paul Eggert  <eggert@shade.twinsun.com>

        * lib/linebuffer.c (readline):
        Append trailing newline to line.

        * src/comm.c, (writeline): Lines now contain trailing newline.
        * src/uniq.c (find_field, different): Use size_t, not int, for lengths.
        (writeline): Lines now contain trailing newline.
        (check_file): Use size_t, not int, for lengths.
        * src/nl.c (proc_text, check_section, main): More of the same.

        * lib/linebuffer.h (struct linebuffer): Use size_t for sizes.
        src/nl.c (header_del_len, body_del_len, footer_del_len, main):
        Likewise.
        src/uniq.c (find_field, different, check_file): Likewise.

        * lib/linebuffer.c (readline): Silently append trailing
        newline if needed.  Do not bother setting buffer length to 0
        at EOF, since it's not part of the spec and nobody relies on
        it.  Do not compute the difference between unrelated pointers.

1999-05-25  Paul Eggert  <eggert@twinsun.com>

        * src/tac.c (memrchr): Ifdef out this unused function.

1999-05-25  Jim Meyering  <meyering@ascend.com>

        * doc/textutils.texi (Squeezing): Remove misleading square brackets
        from SET1 in the one-word-per-line example.

1999-05-22  Jim Meyering  <meyering@ascend.com>

        * lib/Makefile.am (libtu_a_SOURCES): Remove memchr.c.
        From Ulrich Drepper.

        * Version 1.22m.

1999-05-22  Paul Eggert  <eggert@twinsun.com>

        * doc/textutils.texi: Document locale-specific changes to `sort',
        as well as the new, POSIX-compliant definition of line comparison,
        and -g's more careful treatment of NaNs, infinities and zeros.

        * src/sort.c (general_numcompare): Put exceptional cases
        first, not last, to be consistent with -M.

1999-05-21  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (strtod): Declare if STDC_HEADERS is not defined.
        (general_numcompare): Use strtod, not xstrtod.
        Do not consider partial conversions to be errors.
        Put -infinity at the start, and +infinity at the end;
        follow +infinity with NaNs (sorted by bit pattern),
        and finally by conversion errors.

1999-05-21  Jim Meyering  <meyering@ascend.com>

        * tests/sort/Test.pm (11d): Reverse lines in expected output
        to reflect latest change.
        (use-nl): New test from Paul Eggert.

1999-05-20  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c: Treat the trailing newline as part of the line,
        as required by POSIX.2.

        (struct line, findlines, compare, checkfp, mergefps, sort):
        A line now includes its trailing newline.
        (findlines): Do not replace newline with NUL.
        (memcoll, keycompare): Work even if the data to be compared are
        adjacent strings; this is possible now that lines contain the
        trailing newline.
        (fillbuf): Always have an unused byte at the end of the buffer,
        since memcoll and keycompare want to modify a byte after the last line.
        (sortalloc, mergealloc): Increase by 1, for trailing byte.

1999-05-20  Jim Meyering  <meyering@ascend.com>

        * tests/sort/Test.pm: Add test case from Paul Eggert.

1999-05-20  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (keycompare): Ignore any length difference if the
        localized comparison says the strings are equal.

        * src/sort.c (memcoll, keycompare, compare): Handle NUL
        characters properly when comparing with LC_COLLATE semantics.
        (NLS_MEMCMP): Remove.
        (memcoll): Renamed from strncoll.
        Take separate lengths for each string.
        This function is now invoked only when need_locale.
        (keycompare): Don't copy strings when ignore and translate
        are both NULL.

1999-05-18  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (MONTHTAB_CONST): Renamed from NLS_CONST; the use
        is also changed.  Define to const also if !HAVE_NL_LANGINFO.

        (usage): `,' -> `;' (English typo).

1999-05-17  Eli Zaretskii  <eliz@is.elta.co.il>

        * src/cat.c (main): When stdout is in binary mode, make sure all
        input files are also read in binary mode.

1999-05-16  Jim Meyering  <meyering@ascend.com>

        * Version 1.22l.

1999-05-11  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c: Don't autodetect the locale of numbers and
        months, as this conflicts with POSIX.2 and is tricky to boot.

        (FLOATING_COMMA, NLS_STRNCMP, NLS_MAX_GROUPS,
        NLS_ONE_CHARACTER_STRING): Remove macros no longer used.

        (nls_grouping, nls_fraction_found, nls_month_found, nos_monthtab,
        nls_months_collide, nls_keyhead, us_monthtab): Remove variables no
        longer used.

        (struct nls_keyfield): Remove types no longer used.

        (strncoll_s2_readonly, nls_set_fraction, look_for_fraction,
        nls_month_is_either_locale, nls_numeric_format): Remove functions no
        longer used.

        (monthtab): Now has the role that us_monthtab had, but it's const only
        if ENABLE_NLS is not defined.

        (C_DECIMAL_POINT): Renamed from FLOATING_POINT.  All uses changed.
        (MONTHS_PER_YEAR): Renamed from NLS_NUM_MONTHS.  All uses changed.
        (struct_month_cmp): Renamed from nls_sort_month_comp.  All uses changed.
        Use strcmp, not strcoll, since the user doesn't care about collating
        here.

        (inittables): Read locale data into monthtab, rather than modifying a
        separate month table and futzing with indirection.  Do not worry about
        colliding months, since we no longer autodetect month locale.

        (fraccompare): Don't set no-longer-used variable nls_fraction_found.

        (getmonth): Use strncmp to compare months, since user doesn't care
        about collating here.  Fix bug where code incorrectly assumed that
        strlen (monthtab[lo].name) == strlen (monthtab[ix].name).

        (keycompare, main): Don't autodetect month locale.

        (compare): Don't use NLS_MEMCP in code that can't be executed if
        need_locale is false, as NLS_MEMCP is equivalent to memcmp in that
        case.

        (sort, insertkey, main): Don't autodetect numeric locale.

1999-05-15  Jim Meyering  <meyering@ascend.com>

        * tests/join/Test.pm (trailing-sp): New test for this fix.
        * src/join.c (xfields): Don't interpret a trailing blank as a
        delimiter when e.g. -t: was specified.  From Tim Smithers.

1999-05-12  Jim Meyering  <meyering@ascend.com>

        * tests/Makefile.am (envvar-check): Renamed from check-local.
        (check): Depend on envvar-check so the envvar check is performed
        before all other tests.  Reported by Volker Borchert.
        * tests/.env-warn: Use `%%' place-holder that Makefile.am rule expects,
        so CDPATH is mentioned in the message.  Reported by Volker Borchert.

1999-05-11  Jim Meyering  <meyering@ascend.com>

        * src/sort.c (usage): Split the --help message into two pieces so that
        neither is longer than 2048.  For Irix4's cc.  Reported by Kaveh Ghazi.

1999-05-09  Jim Meyering  <meyering@ascend.com>

1999-05-08  Jim Meyering  <meyering@ascend.com>

        * src/system.h (CHAR_BIT, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM,
        and all the *_MIN and *_MAX symbols): Remove definitions.
        * src/sys2.h: Put the definitions here instead (this file is shared
        between all three *utils packages, while system.h is not).

1999-05-06  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (fraccompare, numcompare): Merge the NLS and
        non-NLS versions into a single function.

        (decimal_point): Now char, since we no longer convert to unsigned
        char.
        (th_sep): Now int, since we use a value out of char range to denote
        the absence of a thousands separator.
        (IS_THOUSANDS_SEP): New macro.
        (USE_NEW_FRAC_COMPARE): Remove.
        (nls_set_fraction): Arg is now char, not unsigned char.
        Set th_sep to CHAR_MAX + 1 if there is no thousands separator.
        (numcompare): Don't convert to unsigned char unless necessary.
        (main): Turn off decimal points and thousand separators if they
        are multibyte characters, as we don't support that yet.

1999-05-06  Paul Eggert  <eggert@twinsun.com>

        * src/system.h (CHAR_MIN, CHAR_MAX): New macros.
        (SCHAR_MIN, SCHAR_MAX): Don't assume that char is signed.

1999-05-06  Paul Eggert  <eggert@twinsun.com>

        * src/sort.c (numcompare): Handle comparison of two negative
        numbers correctly in the ENABLE_NLS case.

1999-05-04  Jim Meyering  <meyering@ascend.com>

        * src/pr.c (usage): Break the usage message into 3 pieces instead of
        only 2.  The strings had grown to be longer than 2048, which evokes
        errors when compiling with Irix4's cc.  Reported by Kaveh Ghazi.

        * src/tsort.c (search_item): Use `1' instead of `+1'.  The latter
        elicits a syntax error from SunOS4's cc.  From Kaveh Ghazi.

1999-05-03  Jim Meyering  <meyering@ascend.com>

        * src/ptx.c <ctype.h>: Don't include.
        [!STDC_HEADERS]: Remove definitions of ctype macros.

        * src/sort.c (usage): Document the differences between the
        obsolescent, +POS1[-POS2] form, and the POSIX -k option.

        (handle_line_error): Use human_readable to print lines_required.
        (parse_repeat_count): Parse a uintmax_t.

        * Version 1.22j.

        * Makefile.maint (my-distcheck): Use AMTAR, not TAR.

        * src/sort.c (usage): s/DIRECT/DIRECTORY/g
        Rename global: s/temp_file_prefix/temp_dir/.
        (NAME_MAX_IN_DIR): Rename from PATH_MAX_IN_DIR.  Use _POSIX_NAME_MAX,
        not _POSIX_PATH_MAX.  Guard with #if HAVE_PATHCONF rather than
        #if HAVE_UNISTD_H.
        (tempname): Wrap after 99999 only for length-impaired file systems.

1999-04-17  Jim Meyering  <meyering@ascend.com>

        (check-local): Warn about CDPATH in the same way
        we warn about POSIXLY_CORRECT, since the cp/same-file test fails at
        least when using bash with CDPATH set.  Reported by Mark Hewitt.

        * src/pr.c Add comments.
        (init_header): Tweak white space in Date/Time header.
        * tests/pr/Test.pm: Updated all tests to reflect the big
        1999-02-13 change.  From Roland Huebner.

1999-04-12  Jim Meyering  <meyering@ascend.com>

        * src/cat.c (main): Declare out_dev to be of type dev_t, not `int'.

        From John Bley.

        * src/od.c (MIN, MAX): Remove definitions.
        * src/sys2.h (MIN, MAX): Define here instead.
        Reported by John Bley.

        (tail_lines): Don't call dump_remainder here.
        (file_lines): Call dump_remainder here instead.
        Reported by Lehti Rami.

        * lib/readtokens.c (readtoken, readtokens): Protoize.

1999-04-10  Jim Meyering  <meyering@ascend.com>

        this instead.

        * src/tail.c (recheck): Factor out a block of duplicated code.
        Set f->size to 0 upon encountering a new file so we read it from
        the beginning rather than from the end of the first line or
        block.  Otherwise, after a log rotation, tail would omit the first
        line or block of the new file.  Reported by Ed Avis.

1999-03-20  Jim Meyering  <meyering@ascend.com>

        the file `a' didn't grow longer than two lines.  Now it grows
        without bound.

1999-03-07  Jim Meyering  <meyering@ascend.com>

        With help from Eli Zaretskii.

        * src/pr.c (usage): Add missing \n\.

        * tests/md5sum/newline-1: New file.

        separator TAB with single column output.

        now prefer `text columns of equal width' rather than a consequent
        use of `default n-separator TAB'.
        (add_line_number): Change line number cut-off from lower-oder to
        higher-oder digit to avoid loss of information; no consequent
        handling exists in different utilities and other UNIXes.
        (char_to_clump): Expand input text tabs to 8 spaces, if
        input_tab_char doesn't equal TAB (adapted to other UNIXes).
        (usage): Update POSIX compliant options -s, -w; add new options -J,
        -S, -W.
        (main): Update the source internal documentation.

        numcompare): Remove the `unsigned' from some `unsigned char*'
        parameter types.  Add casts via UCHAR where necessary to avoid

1998-01-17  Jim Meyering  <meyering@na-net.ornl.gov>

        * src/split.c (next_file_name): Rewrite.  This removes an artificial

        * src/tr.c (main): Make sure c1 is not -1 before using it as an
        array index.  Patch from Greg McGary.  Although this is truly a

        to generate invalid output.

        (parse_options): Remove unnecessary goto and label.

        * tests/sort-test/mk-script.pl: Interpret `input arg is a hash
        reference' as meaning that the tested program will read no input.

Tue Jan 21 22:49:00 1997  Jim Meyering  <meyering@na-net.ornl.gov>

        * src/tail.c (main): Properly handle what the POSIX spec calls
        the `obsolescent' usage (e.g., tail +2c).  It didn't work.
        Reported by Karl Heuer.

Sun Jan 12 22:13:27 1997  Jim Meyering  <meyering@na-net.ornl.gov>

        * tests/tr-test/Test.pm: Rename tests so that the associated files

        * lib/getopt.c: New (more POSIX compliant) version from GNU libc.
        [_]: Define to gettext also if ENABLE_NLS is defined.
        This is temporary.

Thu Jan  2 21:17:50 1997  Jim Meyering  <meyering@na-net.ornl.gov>

        * src/pr.c (init_fps): Initialize lines_stored field in three places.
        This avoids uninitialized memory reads in close_file.

        * tests/tr-test/mk-script.pl: Symlink through CVS repo to join's
        mk-script.pl.

        I don't accidentally modify it instead of the one with the .pl suffix.

        * acinclude.m4 (jm_SYS_PROC_UPTIME): Require AC_PROG_CC, rather than
        now-obsolete AC_C_CROSS.
        (jm_FUNC_MKTIME): When redefining, use rpl_ prefix, not gnu_ one

        * acinclude.m4 (jm_SYS_PROC_UPTIME): Fix typo in cache variable
        name for cross compiling.
        Remove definitions of gettext-related macros.  The gettext
        installation procedure installs corresponding .m4 files so that
        aclocal will use them.

1996-12-12  Paul Eggert  <eggert@twinsun.com>

        * system.h (ISDIGIT): Replace with smaller, faster edition
        that yields nonzero only on ASCII digits.

        * configure.in (AM_CONFIG_HEADER): Use it.
        (AC_OUTPUT): Remove stamp-h timestamping statement.
        Now, AM_CONFIG_HEADER does it automatically.
        * lib/Makefile.am (noinst_LIBRARIES): Rename to libtu.a as per

        the invalid identity mappings [:upper:] to [:upper:] and [:lower:]
        to [:lower:].
        (class_ok): Update table to reflect that tr now allows these
        identity mappings.  Suggestion from Risto Kankkunen.

        * src/csplit.c (process_regexp): Update CURRENT_LINE only if
        the new value would be larger.  This avoids the infinite loop
        otherwise provoked by situations like this:
        printf "\na\n" | csplit - '/a/-1' '{*}'
        From Jens Schmidt.

Tue Nov 19 23:16:57 1996  Jim Meyering  <meyering@na-net.ornl.gov>

        * configure.in (AM_SANITY_CHECK_CC): Remove it.  Autoconf-2.11

        (checkfp): Fix off-by-one error that resulted in writing one byte
        beyond the end of a malloc'd buffer.  It caused `sort -c' to segfault
        on Linux systems having a relatively recent libc.  Before, running
        the command, perl -e "print 'x' x 30, \"\n\";"|sort -c
        would provoke the memory overrun (though not necessarily the failure).
        Add an assertion.
        Reported by Risto Kankkunen.

Thu Oct 31 17:48:24 1996  Jim Meyering  <meyering@na-net.ornl.gov>

        This avoids a spurious UMR report from purify.
        (prjoin): Add an assertion.

        * src/tr.c (get_next): Rewrite to treat lower/upper mapping as a
        special case.
        (main): Write separate loops to initialize mapping for lower->upper
        and upper->lower conversion.
        Reported by Arne Henrik Juul.

        * lib/xstrtol.c (__xstrtol): Return an error for invalid suffix.
        Before, e.g., `split -b 1M' would be silently accepted and treated

        (main): Update callers to use combination of error (0, 0, ... and
        usage (EXIT_FAILURE).

        * lib/memcpy.c [HAVE_CONFIG_H]: Include config.h.

        output.

        * src/md5sum.c (usage): Remove references in --help output to
        the now-deprecated --string option.  Support for it will be
        removed soon.  Using this option can provoke a memory access
        violation on some systems because of (unavoidable in an efficient
        implementation) alignment assumptions made by functions in md5.c.
        md5sum.c could leave the option in and accomodate the alignment
        restriction, but this option was intended solely for testing, and
        the tests are now all file-oriented, so it's not necessary.

        * tests/md5sum-test/md5-rfc: Rewrite to avoid use of --string option.

Sun Sep 22 09:24:22 1996  Jim Meyering  <meyering@na-net.ornl.gov>

        * src/sort.c (keycompare): Declare translate to be unsigned char *.
        Otherwise, sign extension caused misordering when using e.g. -f.
        Reported by Erick Branderhorst.
        * tests/sort-test/Test.pm: Add Erick's test for that fix.

        From Kaveh Ghazi.

Sun Sep  8 13:55:18 1996  Jim Meyering  <meyering@na-net.ornl.gov>

        * checks/sort-test/build-script.pl: Prefix $in with \$srcdir/
        so make check works with VPATH build.  From Uli Drepper.

        * src/system.h: Add comments justifying IS* versions of ctype.h macros.

        (AC_REPLACE_GNU_GETOPT): Remove.
        (AC_PATH_PROG): Find perl -- needed only for checks if you
        change or remove things with e.g. make maintainerclean.

        * acinclude.m4: New file -- derived from aclocal.m4.
        * aclocal.m4: This file is now generated by the aclocal program

        `printf '  ' |unexpand -t 1,2' generated no output.

        * src/md5sum.c (md5_check): Remove parameter, BINARY.
        Rename local TYPE_FLAG to BINARY, so md5_file uses the binary mode

        (main): Fail with a diagnostic if --binary or --text is specified
        when verifying checksums.
        Reported by Eli Zaretskii <eliz@is.elta.co.il>.

        when invoking `echo '  ' |unexpand -t 1,2': use print_tab_index, not
        tab_index in inner flush_pend: while loop.  From Keith Owens
        <kaos@audio.apana.org.au>.

        so that DYNIX/ptx V4.1.3 doesn't use `-Xc -D__EXTENSIONS__' -- with
        those options on that system, sys/stat.h gets compile errors.
        With help from Marcus Daniels.

Tue Jul  9 18:07:23 1996  Jim Meyering  <meyering@na-net.ornl.gov>

        * src/fmt.c (MAXCOST): Use `(unsigned long)1' rather than `(COST)1'
        so the left operand of the << isn't signed.
        From Kjetil Torgrim Homme.

        * po/Makefile.in.in (install-data): Don't install NLS files when
        they're not requested.  From Ulrich Drepper.  Reported by

        in the file name to the string, "\\n", and each backslash to "\\\\".
        File names that don't contain NEWLINE aren't translated.
        (split_3): Rewrite to handle file names with embedded newlines.
        Miles Bader and Jim Blandy suggested this new encoding scheme.

        * src/md5sum.c (md5_file): Replace obsolete comment with a description
        of the function.
        (md5_check): Don't use "s"-adding trick to form the plural of
        `checksum.'  That doesn't work well with translation.
        Suggestions from Ulrich Drepper.

        * tail.c (main): Interpret the old-style +VALUE and -VALUE options
        like -c VALUE and -c +VALUE (resp) when VALUE has one of the [bkm]
        suffix multipliers.  This makes the code consistent with --help
        output.  Reported by Karl Heuer.

        * sort.c (limfield): #ifdef-out a block of code that makes
        GNU sort incompatible with Unix sort when a key-end spec refers

        (main): Don't give diagnostic here when decode_format_string fails.
        Remove assertions that could fail on some Crays because they don't

        * Makefile.in (all et. al.): If make was invoked with -k and a
        sub-make fails, fail after the loop rather than exiting right away.
        Otherwise, make's -k option could be ineffective.

Sat Nov 18 12:04:30 1995  Jim Meyering  (meyering@comco.com)

        This is necessary on at least Digital UNIX (aka OSF1) 3.2C.
        Otherwise, running `cat << X > $$' would fail with `cat: -: input
        file is output file'.  From Jarkko Hietaniemi <jhi@epsilon.hut.fi>.

        * sort.c (check): Print `disorder on...' message on standard error,
        not stdout.  This is a minor concession to POSIX which says
        `no output shall be produced...'.

        * sort.c (main): Fix -k so it works. -k 2,3 was being treated
        like -k 2.  Reported by Marcus Daniels <marcus@sysc.pdx.edu>.

Wed Jul 26 22:54:48 1995  Jim Meyering  (meyering@comco.com)

        * man/Makefile.in (install, uninstall): Strip off `.1', not just `1'

        When giving a diagnostic for a line with invalid format, also report
        the line number.
        (main): Generate output after a successful md5_file call.
        [in many places]: Upon detection of an error, rather than exiting
        immediately, issue a diagnostic, note that an error occurred and
        exit later.

        * tail.c (tail_bytes) [from_start]: For regular files, seek

        [!from_start]: Don't back up past the initial position of the
        input file pointer.
        (tail_lines): Call file_lines only if FD refers to a regular file
        with its file pointer positioned at beginning of file.  Otherwise,
        call pipe_lines.  This is a kludge.  Once there's a decent test
        suite, fix this properly.
        Before, (echo 1; echo 2) > k; sh -c 'read x; tail' < k
        would output both lines of the input file even though the first had
        already been read.  Reported by John Roll (john@panic.harvard.edu).

        * md5sum.c [_LIBC || STDC_HEADERS] (TOLOWER): Define to tolower.

Sat Jul 22 00:16:01 1995  Jim Meyering  (meyering@comco.com)

        * md5sum.c (md5_check): New function -- extracted from main.

Fri Jul 21 01:21:49 1995  Jim Meyering  (meyering@comco.com)

        * md5sum.c (md5_file): New function -- extracted from main.
        (main): Call the new function instead of doing all that in an
        if-stmt. Always use "%s" format rather than raw filename as
        format argument in printf-style functions like error.  Otherwise,
        filenames containing `%' are likely to lose.
        Remove all mention of `old format'.
        (split_3): No longer parse the `new format.'  There is only one
        valid format now: the compatible one.

        * lib/Makefile.in (SOURCES): Add md5.c.
        (OBJECTS): Add md5.o.
        (DISTFILES): Add md5.h.
        (md5.o): Depend on md5.h.

        * system.h [!EXIT_FAILURE, !EXIT_SUCCESS]: Define them.
        * lib/md5.c (md5_stream): Check for read failure and return
        indication of success rather than second argument.
        * lib/md5.h (md5_stream): Update prototype.
        [__P]: Define macro.
        * md5sum.c: Use EXIT_FAILURE and EXIT_SUCCESS.
        (main): Report an error if md5_stream fails.  Otherwise, running
        `md5sum dir-on-mounted-filesystem' always reported the checksum
        for an empty file.  Now it gets the `is a directory' error.
        Greg McGary (gkm@magilla.cichlid.com) reported that the released
        version got stuck in an infinite loop with such arguments.

        * lib/md5.c: New file.
        * lib/md5.h: New file.
        * md5sum.c: Rewritten to use library interface.
        From Ulrich Drepper.

Sun Jul 16 18:42:34 1995  Jim Meyering  (meyering@comco.com)

        * configure.in: Add AC_C_INLINE: md5sum.c uses inline keyword.

Tue Jul 11 21:56:02 1995  Jim Meyering  (meyering@comco.com)

        * md5sum.c Add #else block after #ifdef VMS.
        (main): Rename local variable.
        Detect and report failed fclose calls on stdout and checkfile_stream.

        * tr.c (unqote): Comment out unreachable break stmts.
        (append_range): Declare FIRST and LAST parameters to be unsigned int,
        not size_t.
        (find_closing_delim): Clean up interface, separating boolean success
        indicator and index.
        (find_bracketed_repeat): Likewise.
        (build_spec_list): Adapt to use new interfaces.
        Declare CLOSING_DELIM_IDX and CLOSING_BRACKET_IDX to be of
        type size_t, not int.
        (main): Declare NR and CHARS_READ to be of type long, not int.

        * sort.c (main): Comment out unreachable break stmt.

        * tail.c (tail): Explicitly cast to long the N_UNITS argumennt in
        call to tail_lines.  Otherwise, NetBSD lost because N_UNITS (of type
        off_t, a 64-bit type on NetBSD) wasn't converted to the target type,
        long.  Reported by Dan Hagerty (hag@gnu.ai.it.edu).

        * comm.c: Reorder functions so main is last, so no forward dcls
        are needed.

Sun Jul  9 11:41:15 1995  Jim Meyering  (meyering@comco.com)

        * sort.c (main): When using obsolescent +pos -pos syntax, allow
        omission of field spec only when character offset is specified.
        Otherwise, -. +. would be accepted.

Sat Jul  8 13:48:06 1995  Jim Meyering  (meyering@comco.com)

        * sort.c (main): Allow field spec, M, to be omitted in +M.N or -M.N
        position specification.  For compatibility with existing practice
        (what vendors?), omitting M is now equivalent to specifying `0' for M,
        but only when using the +pos -pos syntax, not with the -k option.
        From Rick Sladkey (jrs@world.std.com).

Thu Jul  6 23:44:20 1995  Jim Meyering  (meyering@comco.com)

        * od.c (dump): Correct loop-termination criterion.
        Before, running `printf 1234| ./od --width=4 --read-bytes=4'
        printed output for 8 bytes -- the last four were garbage.
        This happened only when the dump limit, N, was specified (with
        --read-bytes=N) and N was a multiple of bytes_per_block
        (usually 16, but 4 in this example).  From Andreas Schwab.

Sun Jul  2 22:12:40 1995  Jim Meyering  (meyering@comco.com)

        * lib/Makefile.in (check): Depend on libtu.a.

        * md5sum.c (split_3): Rewrite to parse Plumb/Lankester format as well.
        (main): Print each sum line in (de facto) standard Plumb/Lankester
        format.
        New option: --quiet.
        Check option no longer takes an argument.
        When checking, exit status reflects success.

Sat Jun 24 16:18:01 1995  Jim Meyering  (meyering@comco.com)

        * md5sum.c [__GNUC__]: Don't conditionalize use of "inline".
        Autoconf (via config.h) defines it away for compilers that don't
        grok it.

        * cat.c, comm.c, join.c, sort.c, uniq.c: Undefine min/max before
        defining to avoid redefinition warning on some systems.

        * csplit.c (read_input): Rename paramater MAX to MAX_N_BYTES.
        This avoids potential conflict with max macro from some system's
        header files when using bad pre-ANSI compilers.

        * uniq.c (usage): Fix typo in text of --help output.
        From Steve McConnel <steve@acadcomp.sil.org>

        * md5sum.c [uint32]: When testing for 32-bit arithmetic type,
        also check `unsigned long', as a concession to systems with
        int's smaller than 32 bits.

        * configure.in (AC_REPLACE_FUNCS): Remove memcmp (again!) since
        AC_FUNC_MEMCMP already handles it.  This avoids warnings from
        ranlib on nextstep systems.  From Kaveh Ghazi.

        * csplit.c (interrupt_handler): Declare to have a single integer
        parameter.  Otherwise, some compilers fail with a type mismatch
        error in sa_handler assignment.

        * fmt.c [word]: Redefine.  Otherwise, systems (Unicos for one) with
        headers that typedef `word' get syntax errors because of the
        variable by the same name.

        * join.c [join]: Redefine to avoid conflict with prototype in some
        system header file.  Also for Unicos.

        * md5sum.c (main): Remove spurious colon in getopt spec string.
        From Ken Pizzini <kenp@spry.com>.

Tue Jun 20 06:59:16 1995  Jim Meyering  (meyering@comco.com)

        * md5sum.c (md5_file): Initialize two elements of LEN portably,
        rather than with ANSI aggregate initialization.  Reported by
        Edzer Pebesma <Edzer.Pebesma@rivm.nl>.

Sun Jun 18 09:15:57 1995  Jim Meyering  (meyering@comco.com)

        * Version 1.12.

        * md5sum.c (process_buffer): Copy values from struct into
        individual local variables before performing computation on them,
        then copy results back into returned struct.  Solely for better
        optimization by compilers that can't keep struct members in
        registers.  From Ulrich Drepper.

Thu Jun 15 22:09:14 1995  Jim Meyering  (meyering@comco.com)

        * md5sum.c: Remove unnecessary uses of `defined' in #if* tests.
        Don't use #elif.  Some older compilers don't grok it.
        (split_3): New function to parse out sum, flag, and filename
        when reading check file.
        (hex_digits): Remove length parameter since string parameter is
        now nul-terminated.
        (main): Don't allocate separate arrays for filename and sum
        when checking.  Get pointers into line buffer with split_3 instead
        of using sscanf.
        (main): Treat `no file args' just like `-' when not checking
        or using strings.
        (hex_digits): Unprotoize.

        * md5sum.c (main): Don't use a separate loop to convert to lower
        case.  Suggested by Ulrich Drepper.
        (CLOSE): New macro.
        (md5_file): Use it.
        From Ulrich Drepper.

        * md5sum.c: Don't include values.h.
        [__P]: Undefine it.

        * md5sum.c: [UNIX || unix]: Also test __UNIX__, __unix__,
        and _POSIX_VERSION.  Reported by Arne H. Juul.

Tue Jun 13 21:20:10 1995  Jim Meyering  (meyering@comco.com)

        * tr.c [NDEBUG]: Define it to disable assertions.  Some systems
        have a broken <assert.h> header.
        (is_char_class_member): Set a variable in each branch of switch
        stmt and return that value after the switch (rather than returning
        directly from every branch).
        (unquote): More int->size_t changes.
        (build_spec_list): More int->size_t changes.
        Be very careful about comparison now that variables are unsigned:
        Use i + 2 < len rather than i < len - 2.  The latter didn't work
        for len < 2.  Caught early thanks to a thorough regression test
        suite.

Mon Jun 12 23:07:59 1995  Jim Meyering  (meyering@comco.com)

        * sort.c (xfclose): Don't try to flush stdin, only stdout.
        Otherwise, at least Ultrix-4.3's fflush would return EOF.
        Reported by Jim Blandy (jimb@cyclic.com).

        * tr.c (non_neg_strtol): Don't compare signed and unsigned.
        [struct Spec_list] (indefinite_repeat_element): New member.
        Use size_t rather than int or unsigned long where reasonable.
        (get_spec_status): Make interface cleaner.
        (get_s1_spec_status): New function.
        (get_s2_spec_status): New function.
        (validate): Use new functions instead of get_spec_status.

Sun Jun 11 00:39:50 1995  Jim Meyering  (meyering@comco.com)

        * md5sum.c: New file.  From Ulrich Drepper.
        * md5-test.rfc: New file.
        * Makefile.in (PROGS): Add md5sum.
        (check): Run a recursive make in each subdirectory.
        * man/Makefile.in (MANFILES): Add md5sum.1.
        * src/Makefile.in (SOURCES): Add md5sum.c.
        (OBJECTS): Add md5sum.o.
        (PROGS): Add md5sum.
        (check): Add basic checks for md5sum.
        (md5sum): Add dependency and link rule.
        (DISTFILES): Add md5-test.rfc.

        * tr.c (look_up_char_class, append_char_class, append_equiv_class):
        Use const attribute when appropriate.

Sun May 28 14:48:58 1995  Jim Meyering  (meyering@comco.com)

        * join.c: Overhauled to make -a1 and -a2 options work.
        Passed all tests in a fairly thorough test suite.
        Reported by Michael Hasselberg (mikelh@zonta.ping.de).

Sat May 27 00:35:47 1995  Jim Meyering  (meyering@comco.com)

        * tail.c (main): Remove dcl of and statements that set now-unused
        variable.

        * system.h [!STDC_HEADERS && HAVE_MEMORY_H]: Include memory.h.
        Without this, SunOS doesn't get type for memchr.
        Reported by Kaveh Ghazi.

Thu May 25 00:06:50 1995  Jim Meyering  (meyering@comco.com)

        * tail.c (tail_lines): Change one more `long' to `off_t'.
        Otherwise, tail didn't work on NetBSD.  From Arne H. Juul.

        * csplit.c [struct control]: Change type of `repeat' to unsigned
        long to avoid conversion warning.

Sun May 21 07:50:00 1995  Jim Meyering  (meyering@comco.com)

        * Makefile.in (.PHONY): TAGS is not a phony target.  From Franc,ois.

        * xstrtol.c (__strtol): Remove prototype altogether.
        Move inclusion of xstrtol.h back so that it follows system headers.

        * Version 1.11.2.

Sat May 20 06:44:14 1995  Jim Meyering  (meyering@comco.com)

        * join.c (ADD_FIELD): Declare in K&R style, not ANSI.
        From Kaveh Ghazi.

        * xstrtol.c: Define NDEBUG for systems with losing assert.h.
        (__strtol): Add __unsigned to prototype and use __P.
        Move inclusion of xstrtol.h to precede prototype.
        From Kaveh Ghazi.

        * memmove.c: Include config.h for definition of const.
        From Kaveh Ghazi.

        * All Makefile.in (install-exec, install-exec): New targets.
        From Karl Berry.

        * tr.c (look_up_char_class): Take a string length argument -- required
        because the argument is a string that is *not* NUL-terminated.
        Use strncmp, not strcmp and add string lengths comparison.
        (append_char_class): Update caller.  Before this change,
        tr '[:upper:]' '[:lower:]' read one uninitialized byte.
        From Andreas Schwab.

        * split.c (next_file_name): Move dcls of file-scope variables into
        this function.  Don't rely on arithmetic being two's complement.

        * paste.c [CLOSED, ENDLIST]: Don't cast constants to FILE pointers.
        Instead, declare two FILE structs and use their addresses.

        * csplit.c (record_line_starts): Remove set-but-not-used,
        file-scope variable.

Sat May 13 08:57:20 1995  Jim Meyering  (meyering@comco.com)

        * all source files (usage): Include one- or two-line synopsis
        in --help output.  From Karl Berry.

        * lib/Makefile.in [.c.o]: Remove -I. since safe-l?stat.h are no
        longer used.

Wed May 10 22:26:35 1995  Jim Meyering  (meyering@comco.com)

        * Version 1.11.1

Sun May  7 13:35:49 1995  Jim Meyering  (meyering@comco.com)

        * all Makefile.in (maintainer-clean): Renamed from realclean
        per GNU Standards.

Thu May  4 23:15:58 1995  Jim Meyering  (meyering@comco.com)

        * sort.c (main): Use stat, not safe_stat.  The latter was unnecessary.
        Don't include safe-stat.h.

        * lib/Makefile.in (DISTFILES): Remove safe-xstat.hin.
        Remove all associated rules.  safe-l?stat.h are no longer used.

        * sort.c Don't hard-code /tmp.
        [DEFAULT_TMPDIR]: Use this instead.
        * tac.c (save_stdin): Likewise.

        * sort.c (set_ordering): Properly parse arguments like `+x.yn'.
        Reported by John Salmon (johns@mullet.anu.edu.au).
        Patch from Mike Haertel.

Wed Apr 26 23:48:13 1995  Jim Meyering  (meyering@comco.com)

        * sort.c (tempname): AND-off high bits of pid so that its decimal
        string representation is no longer than five digits.
        From Hans Verkuil (hans@wyst.hobby.nl).

Thu Apr 20 23:09:33 1995  Jim Meyering  (meyering@comco.com)

        * expand.c (add_tabstop): Give correct size when reallocating
        tab_list buffer.  From Geoff Odhner (geoff@franklin.com).
        Reproduce with expand --t=`perl -e "print join (',', (1..300));"`.

Tue Apr 18 22:57:43 1995  Jim Meyering  (meyering@comco.com)

        * configure.in (AC_OUTPUT): Use echo, not date, to avoid creating
        unnecessary conflicts for people using version control software
        like RCS and CVS.
        (AC_ARG_PROGRAM): Use it.

Thu Apr 13 23:22:57 1995  Jim Meyering  (meyering@comco.com)

        * head.c: Remove block of redundant comments describing options.
        (usage): Remove reference to -l option.  It's not valid.

        * od.c (write_block): Declare index I as unsigned int, not int.
        (get_lcm): Likewise.
        (dump_strings): Likewise.
        (main): Likewise.
        (dump): Cast BYTES_PER_BLOCK to off_t in MIN expression.
        (dump_strings): Declare bufsize to be of type size_t, not int.

        * split.c (next_file_name): Don't reuse X as an index.
        Declare new variable I instead.

Sat Mar 25 15:07:23 1995  Jim Meyering  (meyering@comco.com)

        * csplit.c: Declare as `unsigned int' all variables that were
        just `unsigned'.
        (make_filename): Change type of arg to unsigned int.
        (split_file): Change type of indices to unsigned int.

Thu Mar 16 22:05:05 1995  Jim Meyering  (meyering@comco.com)

        * od.c (main): Detect and fail when argument to -N is too large
        to fit in an off_t.

Sun Mar 12 12:02:39 1995  Jim Meyering  (meyering@comco.com)

        * configure.in (AC_REPLACE_FUNCS): Add memcmp.c.
        Remove check for sizeof long.

        * linebuffer.h: Undefine __P before defining it.
        * long-options.h: Likewise.
        * xstrtol.h: Likewise.

        * memcpy.c: New file.
        * lib/Makefile.in (SOURCES): Add memcpy.c.

Fri Mar 10 21:14:11 1995  Jim Meyering  (meyering@comco.com)

        * src/*.c: Update Copyright dates.

Sat Feb 11 07:31:08 1995  Jim Meyering  (meyering@comco.com)

        * system.h: Remove index/rindex and bcmp/bcopy/bzero references.
        Separate errno declaration from STDC_HEADERS.

        * wc.c (wc): For efficiency, handle separately the cases in which
        words need not be counted.  Suggested by Karl Heuer.

        * wc.c (wc): Don't overcount the number of bytes when reading
        from a regular file on stdin with file pointer not at BOF.
        From Karl Heuer <karl@gnu.ai.mit.edu>.  Before, the command
        `(dd ibs=99k skip=1; wc -c) < /etc/group' made wc wrongly output
        the size of the file.  Now it outputs `0'.

Sat Jan 28 07:07:23 1995  Jim Meyering  (meyering@comco.com)

        * cat.c (cat): Use memmove rather than bcopy.
        * csplit.c (load_buffer): Use memcpy rather than bcopy.
        (extract_regexp): Use strrchr, not rindex.
        * fmt.c (isopen, isclose, isperiod): Use strchr, not index.
        (flush_paragraph): Use memmove instead of bcopy.
        * fold.c (fold_file): Use memmove instead of bcopy.
        * od.c (decode_format_string): Use memmove instead of bcopy.
        [EQUAL_BLOCKS]: Use memcmp, not bcmp.
        (parse_old_offset): Use strchr, not index.
        (dump): Use memset, not bzero.
        * sort.c (checkfp, mergefps): Use memcpy instead of bcopy.
        (fillbuf): Use memmove instead of bcopy.
        * split.c (main): Use memset, not bzero.
        (line_bytes_split): Use memmove instead of bcopy.
        * tac.c (tac): Use memmove instead of bcopy.
        (output): Use memcpy instead of bcopy.
        * tail.c (pipe_lines, pipe_bytes): Use memcpy instead of bcopy.
        * tr.c (substr): Use memcpy instead of bcopy.
        (card_of_complement, set_initialize): Use memset, not bzero.

        * tr.c (substr): Don't allocate a byte for trailing NUL in result
        since the result needn't be NUL-terminated.  Don't NUL terminate it.

        * configure.in (AC_REPLACE_FUNCS): Check for memmove and memcpy,
        not bcopy.
        (AC_CHECK_FUNCS): Add strchr and strrchr.

        * lib/Makefile.in (SOURCES): Add memmove.c and memcpy.c.
        * memmove.c: New file.
        * memcpy.c: New file.

Tue Jan 24 22:18:19 1995  Jim Meyering  (meyering@comco.com)

        * fmt.c (copy_rest): Replace `||' with `&&'.  Before, a paragraph
        not followed by a newline would be followed by data copied from
        uninitialized storage.  Repeat by `printf abc|fmt|od -ac'.
        Reported by Franc,ois Pinard.

        * od.c: Rename macros with FP_ prefix.  Use FLOAT_ instead.
        AIX-2.2.1 declares a typedef, FP_DOUBLE, that conflicted.
        Be careful to use off_t instead of explicit `unsigned long'.
        Otherwise, systems like 4.4BSD lose on calls to fseek that
        expect off_t (which is long long on that system).
        (parse_old_offset): Use xstrtoul
        (main): Likewise.

        * src/Makefile.in (od.o, tail.o): Depend on ../lib/strtol.h.

Mon Dec 19 22:13:55 1994  Jim Meyering  (meyering@comco.com)

        * tail.c (numerous functions): Give char* filename arguments the
        const attribute.

        * lib/Makefile.in (SOURCES): Remove xwrite.c.  It was no longer used.
        Add xstrtol.c and xstrtoul.c.
        (OBJECTS): Likewise for .o files.
        (DISTFILES): Add error.h and xstrtol.h and xstrtoul.h.

        * lib/Makefile.in (DISTFILES): Remove safe-xstat.cin.

        no corresponding argument.

        * src/*.c: Include "error.h" instead of simply declaring
        `void error ();'.
        * od.c (main): Use %lu, not %d for unsigned long.
        (my_strtoul, uint_fatal_error): Remove functions.  Use xstrtoul
        and STRTOL_FATAL_ERROR instead.

Sun Dec 11 17:24:09 1994  Jim Meyering  (meyering@comco.com)

        * sort.c (main): Fix interpretation of field offsets when specified
        via -k option.  They were being interpreted as zero-indexed.  POSIX
        says they are 1-based indices.  From Rik Faith <faith@cs.unc.edu>.
        (keycompare): Don't ignore characters at the end of words when
        otherwise they would compare equal.  From Rik Faith.

        * tail.c (<most functions>): Change the type of n_units/n_lines/n_bytes
        to off_t because n_bytes is used as the option to fseek and off_t may
        be long long (e.g. on BSD4.4).  The only place where a 32-bit limit is
        imposed is in the string-to-integer converstion of xstrtol.
        (main): Use xstrtol instead of manual string to integer conversion.

        * csplit.c (get_format_width, get_format_prec): Use ISDIGIT instead of
        comparisons against '0' and '9'.

        * tr.c [!ULONGMAX]: Define it.
        [!LONGMAX]: Define in terms of ULONGMAX instead of as a 32-bit constant.

        * full-write.c: Declare (or not) errno based on definedness or
        errno, not STDC_HEADERS.
        * safe-read.c: Likewise.
        * xwrite.c: Likewise.

Thu Nov 17 06:37:33 1994  Jim Meyering  (meyering@comco.com)

        * tail.c (dump_remainder): Flush standard output just before
        sleeping so that `tail -f' will output partial lines sooner.
        This applies only when following the end of a single file.
        From Leonard N. Zubkoff <lnz@dandelion.com>.

        * tail.c (file_lines, pipe_lines, pipe_bytes, start_bytes,
        start_lines, dump_remainder): Use STDOUT_FILENO instead of `1' in
        XWRITE calls.
        * tac.c (output): Use STDOUT_FILENO instead of `1' in xwrite call.

        not already defined.

Wed Nov 16 07:01:38 1994  Jim Meyering  (meyering@comco.com)

        * tail.c: Use BUFSIZ instead of BUFSIZE.

        * cut.c: Declare DELIM to be `int' rather than unsigned char.

        * fmt.c: Use index, not strchr -- per GNU Standards.
        Reported by Kaveh Ghazi.
        Always include <config.h>.
        (main): Include program name in --version output.

        Reported by Franc,ois Pinard.

        * src/Makefile.in (DEFS): Remove -Dlint... again.

        * src/Makefile.in (PROGS): Add fmt!

Thu Nov 03 23:23:08 1994  Jim Meyering  (meyering@comco.com)

        * linebuffer.h: Use __P instead of _P since the latter conflicts
        with a definition in some <ctype.h>.  From Kaveh Ghazi.

        * tail.c (XWRITE): Allow n_bytes == 0 but call fwrite only if
        n_bytes is positive.  Turn off assertions.  `tail /dev/null' was
        getting a failed assertion.  Reported by Doug McLaren
        (dougmc@comco.com).

        * cut.c (cut_bytes): Print at least a newline for every line of input.
        (cut_fields): Print a newline even for lines whose only selected
        field is empty.  But print nothing when using -s without -f1.
        And print nothing for empty input.  Reported by
        Richard_Sharman@software.mitel.com.

Tue Nov 01 06:05:23 1994  Jim Meyering  (meyering@comco.com)

        * fmt.c: Change #ifdef __STDC__ to #if defined (__STDC__) && __STDC__.

        * configure.in (AC_REPLACE_FUNCS): Remove memcmp since AC_FUNC_MEMCMP
        already handles it.  From Kaveh Ghazi.

        * {lib,src}/Makefile.in (DEFS): Don't use -Dlint.  Some systems
        get failures when it's defined.  From Kaveh Ghazi.

        * cat.c (cat): Conditionalize test for errno == ENOSYS.  It's not
        defined on some Next and Alliant systems.  From Kaveh Ghazi.

        * sort.c join.c (main): Include version.h and call parse_long_options
        with the proper number of arguments.  Reported by Franc,ois Pinard.

Sun Oct 30 01:30:41 1994  Jim Meyering  (meyering@comco.com)

        * (configure.in): Add AC_OFF_T and rearrange by type along the
        same lines as autoscan.

        * fmt.c, fmt.1: New files.
        Both from Ross Paterson (rap@doc.ic.ac.uk).

        * Makefile.in (PROGS): Add fmt.
        * src/Makefile.in (SOURCES, OBJECTS): Add fmt.c and fmt.o respectively.
        (fmt): Add a link rule.

Sat Oct 08 10:44:30 1994  Jim Meyering  (meyering@comco.com)

        * Makefile.in (All of them): Update from the ones in sh-utils.
        From now on, rules and definitions that are comon to the fileutils,
        textutils, and sh-utils will get ChangeLog entries only in the
        sh-utils.

Tue Oct 04 20:42:46 1994  Jim Meyering  (meyering@comco.com)

        * od.c (my_strtoul): Set errno to zero before calling strtoul.

        * tr.c (main): Give an error and fail when squeezing repeats
        and no non-options are given.  Reported by Tony Robinson
        (ajr@eng.cam.ac.uk).

        * sort.c (main): Temporarily copy each input file that might be
        another name for the output file.  When in doubt (e.g. a pipe),
        copy.  This allows the dangerous (historical -- in cnews) idiom
        `cat file | sort -o file' to work properly.  Don't rely on this
        behavior in new shell scripts.  From Paul Eggert (eggert@twinsun.com).

Mon Sep 26 18:01:47 1994  David J. MacKenzie  (djm@churchy.gnu.ai.mit.edu)

        From Karsten Thygesen <karthy@kom.auc.dk>.

        * wc.c (wc): Optimize for the case when only bytes are being counted
        and the input is not a regular file.  From Jeff Moore <jbm@mordor.com>.

Sun Apr 24 10:54:08 1994  Jim Meyering  (meyering@comco.com)

        * configure.in [AC_SIZEOF_TYPE]: Update for autoconf-1.9.
        * memchr.c: Test SIZEOF_LONG instead of LONG_64_BITS.

        is set.
        (new_control_record): Initialize repeat_forever field.
        (parse_repeat_count): Set it instead of setting repeat count to
        INT_MAX.
        (process_line_count): Abort for internal error instead of calling
        handle_line_error.

        * long-options.c (parse_long_options): Take a new argument indicating
        the utility name (e.g. "join", not "gjoin") for version output.
        Print both the utility and the package names, e.g. `join - GNU
        textutils-1.9.1' instead of just the package name.

        * join.c (main): Call parse_long_options with program name arg.
        * sort.c (main): Ditto.

        * All source except sort.c and join.c (main): Change --version output
        to include utility name as well as package name and version info.

        explicit error message for too many arguments.

Fri Mar 25 18:11:19 1994  Jim Meyering  (meyering@comco.com)

        * configure.in: Use AC_VERBOSE, AC_CHECKING, and AC_WARN instead
        of explicit echo commands.
        [INSTALL]: When AC_PROG_INSTALL resorts to setting this to
        `./install.sh', make it `../install.sh' instead since that
        script will be invoked only from subdirectories.
        [AC_SIZEOF_TYPE]: Use this instead of deprecated AC_LONG_64_BITS.

        * cat.c (cat): The command `:|cat -s' failed on Irix5 because
        ioctl (d, FIONREAD,... now returns ENOSYS for pipes -- under Irix4
        it returned EINVAL.  Detect this.
        (main) [lint]: Initialize variables to suppress `used before
        initialized' warnings.

        * csplit.c: Change long option name from --suffix to --suffix-format.

        * od.c (skip): Correct a comment.

        LDFLAGS and CFLAGS.

Wed Jan 18 16:14:00 1994  Jim Meyering  (meyering@comco.com)

        * unexpand.c (unexpand): Don't segfault when given a name of a

        * src/Makefile.in: Change all link commands to use both $(CFLAGS)
        and $(LDFLAGS).

        * csplit.c (load_buffer): Rather than incrementing buffer size,
        double it each time we fail to find a newline.  Otherwise, csplit
        would run out of memory when processing files with very long lines.

Mon Jan 10 01:20:38 1994  Jim Meyering  (meyering@comco.com)

        * man/Makefile.in (manprefix): Use binprefix as the default.

        * tr.c: Ditto.
        * wc.c: Ditto.

        * tail.c: Replace calls to xwrite with calls to fwrite.
        Use fopen/fclose instead of open/close.
        (write_header): Use a single call to printf instead of four to xwrite.
        Use safe_read instead of read.
        * head.c: Ditto.

Tue Dec 28 15:49:32 1993  Jim Meyering  (meyering@comco.com)

        * install.sh: New file.
        Makefile.in [DISTFILES]: Add it.

        (set_fields): Collect the list of all selected ranges before
        allocating and initializing the boolean lookup table.
        (cut_bytes, cut_fields): Complete rewrite.  Avoid copying
        into buffer whenever possible.  Properly handle input without
        trailing newline.
        (getstr): New function.  Copied from getline.c, but with minor changes.

        * sort.c (main): Properly handle -Tdir.
        Before, `sort -T/var/tmp' gave `sort: unrecognized option `-v''.
        Reported by Kristoffer Rose (kris@diku.dk).

        * cut.c (main): Give separate errors for `-s without -f'
        and `-d without -f'.
        (main): Now -d '' means `use the NUL byte as the delimiter'.
        Before, it got an error.

Mon Dec 20 23:29:30 1993  Jim Meyering  (meyering@comco.com)

        * configure.in [test for 8-bit clean memcmp]: Add a test to detect
        losing memcmp from SunOS4.1.x.  From Robert H. de Vries
        <robert@and.nl>.

Sat Dec 18 01:12:24 1993  Jim Meyering  (meyering@comco.com)

        * configure.in (AC_OUTPUT): Put `touch stamp-config' in second arg
        so it goes in config.status.  This eliminates unnecessary second run
        of configure.

Thu Dec 02 23:53:03 1993  Jim Meyering  (meyering@comco.com)

        * configure.in (AC_HAVE_FUNCS): Add isascii.
        * system.h [!defined (isascii) || defined (STDC_HEADERS)]: This failed
        on AIX PS/2 1.3 systems because isascii is a function and it is used
        in definitions (with the necessary side effect of assigning to a
        global variable) of the is* macros.  Also test HAVE_ISASCII and
        redefine ISASCII(c) instead of isascii.
        Reported by Minh Tran-Le (tranle@intellicorp.com).

Fri Nov 19 22:41:48 1993  Jim Meyering  (meyering@comco.com)

         * configure.in: Don't run the test for 8-bit clean memcmp if we
         already know we'll be using our replacement.

Fri Nov 12 00:44:49 1993  Jim Meyering  (meyering@comco.com)

        * Version 1.9.1.

        * tac.c (usage): Fix typo in long usage.
        * sort.c (usage): Likewise.
        From Philippe.Schnoebelen@imag.fr.

        * cut.c [FATAL_ERROR]: New macro.
        (main): Call both error and usage (2) through FATAL_ERROR in
        many places.  Before, only `error (2...' was called.
        (invalid_list): Removed.  This function is subsumed by FATAL_ERROR.

        * cut.c (cut_fields): Properly handle input lacking a terminating
        newline.  Before, the command  `printf "a\tb" |cut -f 1' generated
        no output.

Tue Nov 09 17:26:25 1993  Jim Meyering  (meyering@comco.com)

        od.c (usage): Change --backward-compatible to --traditional in
        the long usage message.

Sat Nov 06 22:51:31 1993  Jim Meyering  (meyering@comco.com)

        * cut.c (cut_fields): Revert July 27 change.  Instead, strip off
        trailing delimiter unless given a range of fields like `3-' that
        extends to end of line.
        (set_fields): Moved local `eol_range_start' to file-scope.
        Reported by Arne H. Juul (arnej@solan.unit.no).

Tue Nov 02 00:53:41 1993  Jim Meyering  (meyering@comco.com)

        * fold.c (fold_file): Don't get stuck in an endless loop when
        width is smaller than 8 and there are TABs in the input.

Sat Oct 30 15:31:28 1993  Jim Meyering  (meyering@comco.com)

        * join.c: Remove now-unused dcls of show_help and show_version.

Fri Oct 29 13:58:50 1993  Jim Meyering  (meyering@comco.com)

        * csplit.c [INT_MAX]: Make sure it's defined.
        [not HAVE_LIMITS_H]: Don't include limits.h.
        From Kaveh R. Ghazi (ghazi@noc.rutgers.edu).

Wed Oct 27 01:13:52 1993  Jim Meyering  (meyering@comco.com)

        * csplit.c, cut.c, expand.c, fold.c, head.c, nl.c, od.c, paste.c,
        split.c, tac.c, tail.c, unexpand.c, uniq.c: Use the preferred
        `--longopt=arg' syntax in --help message rather than `--longopt arg'.
        From Francois Pinard.

        * tail.c: Don't include <signal.h>.  It hasn't been necessary
        since the Dec 12, 1992 change.

        * join.c (main): Accept `-v 1' again.  Adding the --version
        long option had broken it, although -v1 still worked.  Call
        parse_long_options instead of adding "help" and "version"
        to join's longopt strct.
        * Makefile.in [SOURCES, OBJECTS, DISTFILES]: Add long-options.c

        From Ian Lance Taylor (ian@cygnus.com).

        * od.c: Depend on __GNUC__ || HAVE_LONG_DOUBLE rather than __STDC__
        for long double support;  there are compilers (Stardent Vistra svr4)
        without long double but still define __STDC__.

        * {lib,src}/Makefile.in [.c.o]: Make CPPFLAGS and CFLAGS follow
        other options so users can use them to override DEFS.
        * src/Makefile.in [.c.o]: Add -I$(srcdir) for version.h.

        * Makefile.in [CFLAGS, LDFLAGS]: Don't set to -g explicitely;
        configure's AC_SUBST will set these.

        * Makefile.in [Makefile]: Add dependencies and a rule to remake it.
        [targets that cd then run make in subdirectories]: Don't depend
        on `cd ..';  use a subshell instead.

        New targets but no rules; comply with standards.

        * configure.in [CFLAGS]: Default to -g -O if CC is gcc and the user
        hasn't specified CFLAGS.

        the system's doesn't grok the 8th bit.
        * memcmp.c: Fix it so it groks the 8th bit.
        TODO: We really need to provide a fast memcmp, since most
        machines will have a broken memcmp.  Probably should get
        the one from glibc.
        * sort.c (mergefps): Maintain keybeg and keylim when copying
        the current line to `saved'.

        also to properly handle the global reverse option.

        that cols_ready_to_print not be decremented when printing across.
        The command `echo |pr -2ta' didn't terminate.
        (print_page): Rewrite conditional (that had side effects in second
        conjunct) using nested if statements to make it clear that we do
        indeed want those semantics.

        * tr.c (string2_extend, validate): Give an error message when
        translating without --truncate-set1, with empty string2, and
        with non-empty string1.  "tr 1 ''" produced a failed assertion.

        trailer lines per page.
        * (main): Added restriction that -a and -m are incompatible.
        Although the POSIX spec doesn't explicitly say they shouldn't
        be used together, it says -a modifies the -column option and
        that -column shouldn't be used with -m.

        to step through the input by two.
        * tr.c (set_initialize): Write a comment describing the function.
        * tr.c: Eliminated the variable `portability_warnings' and replaced
        references to it by references to `!posix_pedantic'.  One of the
        uses of portability_warnings had been wrong.

        * system.h, configure, Makefile.in: Don't include memory.h if
        STDC_HEADERS, removing need for MEMORY_H_MISSING.

Thu 17 Oct 1991 16:53:07  Jim Meyering  (meyering at wombat)

        * pr.c (print_page): REALLY fixed `extra newline at EOF' problem.
        Somehow, part of my patch didn't make it last time.

        (fillbuf, main): fread never returns < 0, so check ferror instead.
        From Rainer Orth.

Tue Oct  8 18:07:08 1991  Jim Meyering  (meyering at churchy)

        a  single file with the options `-3 -f'.
        * (print_white_space): Single spaces were being replaced
        with tabs.
        * (print_page): Some lines were getting too much white space
        at the beginning because spaces_not_printed wasn't being reset
        to 0.
        * (read_line): The single space between a truncated column
        on its left and the column on its right was omitted.  Fixed
        so that previous value of input_position is restored before

        Added POSIX -r option to suppress the message.
        * pr.c: Added variables: failed_opens, ignore_failed_opens.
        These changes were based in part on work by David MacKenzie.

        Instead of copying tabs verbatim and flushing pending spaces
        when one is reached, count them as the proper number of
        pending spaces.  Instead of changing tabs to single spaces if
        the tabstop list is exhausted, print the rest of the line
        unchanged (for POSIX).

        copy the rest of the line verbatim.

        * split.c (convint): New function to allow 'm' and 'k' after
        byte counts.
        (main): Use it.  Change -c option to -b for POSIX.

        draft 10 removed it.

        * tac.c (tac_stdin): Use fstat instead of lseek to determine

        Change global vars `countmode' and `mode' from ints to enums.
        (main): Use getopt to parse options and support POSIX options.

        * cmp.c (cmp): Rename `r' to `first_diff', and `x' to `smaller'.
        Remove unneccessary variable `c1'.  If -l was given, increase

        producing output.
        Replace if-else-if constructions with case statements for clarity.
