2000-10-28  Jim Meyering  <meyering@lucent.com>

        * getusershell.c (setusershell) [HAVE_FSEEKO]: Use fseek0.
        Patch by Ulrich Drepper.

        * strftime.c: Update from libc.

2000-10-25  Jim Meyering  <meyering@lucent.com>

        * obstack.c: Update from libc.

2000-10-23  Jim Meyering  <meyering@lucent.com>

        * hard-locale.c (hard_locale): Revert last change -- it was simply
        wrong.  That set_locale call must not have any side effects.
        From Paul Eggert.

2000-10-22  Jim Meyering  <meyering@lucent.com>

        * md5.c (md5_process_block) [OP]: Use `rol', not CYCLIC.
        [CYCLIC]: Remove now-unused definition.

        * save-cwd.c (O_DIRECTORY): Define, if needed.
        (save_cwd) [HAVE_FCHDIR]: Use O_DIRECTORY when opening ".".
        Suggestion from Ulrich Drepper.

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

        * dirname.c (dir_name_r): New function, factored out of dir_name.

        * dirname.c (memrchr): Declare if necessary.
        (dir_name): Remove the restriction that there be no
        trailing slashes.  Now, this code skips past them, effectively
        ignoring them.
        [TEST_DIRNAME] (main): New unit tests.

        * memrchr.c: New file from GNU libc.
        Undef __memrchr, too.

        From Jan Fedak.

2000-09-25  Jim Meyering  <meyering@lucent.com>

        * md5.h (rol): Define (from GnuPG).

        * sha.c: Give credit (GnuPG) where due.

2000-09-10  Jim Meyering  <meyering@lucent.com>

        * getopt.c (_getopt_internal): Update from glibc.

2000-09-09  Jim Meyering  <meyering@lucent.com>

        * quotearg.c: Rename ISASCII to IN_CTYPE_DOMAIN, so people don't
        think it should be used as a general replacement for isascii.
        * fnmatch.c: Likewise.
        * mbswidth.c: Likewise
        * regex.c: Likewise.

        Don't use atoi.

        (parse_user_spec): Use xstrtoul, not atoi when converting numeric
        UID, GID.  Check range.

2000-08-26  Jim Meyering  <meyering@lucent.com>

        * closeout.c: Include "__fpending.h".
        (close_stdout_status): Return right away if there's nothing to flush.

        * Makefile.am (noinst_HEADERS): Add __fpending.h.
        * __fpending.c: New file.
        * __fpending.h: New file.

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

        Standardize on "memory exhausted" instead of "Memory exhausted"
        or "virtual memory exhausted".
        * obstack.c (print_and_abort): Use "memory exhausted", not
        "virtual memory exhausted".
        * same.c (same_name): Invoke xalloc_die instead of printing
        our own message.
        * userspec.c (parse_user_spec): Likewise.
        * bumpalloc.h: comment fix
        * same.c, userspec.c: Include xalloc.h.

        * xalloc.h (xalloc_msg_memory_exhausted): Now char const[],
        not char *const and pointing to a constant array.
        * xmalloc.c (xalloc_msg_memory_exhausted): Likewise.
        (xrealloc): Comment fix.

        * userspec.c (parse_user_spec):
        Don't translate a message until just before returning,
        to avoid unnecessary translation.

2000-08-07  Jim Meyering  <meyering@lucent.com>

        * addext.c, argmatch.c, argmatch.h, backupfile.h, bumpalloc.h,
        chown.c, diacrit.h, dirname.h, dup2.c, exclude.h, fileblocks.c,
        fnmatch.c, fnmatch.h, fsusage.c, fsusage.h, getdate.h,

        utime.c, version-etc.h, xalloc.h, xstrdup.c, xstrtoumax.c,
        yesno.c: Back out Copyright date changes for each file with no change
        this year.  This eases coordination with other programs using the same
        source code modules.  From Paul Eggert.

2000-08-03  Greg McGary  <greg@mcgary.org>

        * regex.c (SET_HIGH_BOUND, MOVE_BUFFER_POINTER,
        ELSE_EXTEND_BUFFER_HIGH_BOUND): New macros.
        (EXTEND_BUFFER): Use them.

2000-08-01  Jim Meyering  <meyering@lucent.com>

        * dirname.c (ISSLASH): Define.
        (BACKSLASH_IS_PATH_SEPARATOR): Define.
        (dir_name) [BACKSLASH_IS_PATH_SEPARATOR]: Handle the case in which
        both `\' and `/' may be use as path separators.
        Based on a patch from Prashant TR.

2000-07-31  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c (quotearg_n_options): Don't make the initial
        slot vector a constant, since it might get modified.

2000-07-31  Jim Meyering  <meyering@lucent.com>

        * xmalloc.c: Use `virtual memory exhausted', not `Memory exhausted'.
        * obstack.c (print_and_abort): Likewise.

2000-07-30  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c (quotearg_n_options): Preallocate a slot 0
        buffer, so that the caller can always quote one small
        component of a "memory exhausted" message in slot 0.
        From a suggestion by Jim Meyering.

2000-07-30  Jim Meyering  <meyering@lucent.com>

        * makepath.c (make_path): Quote the other instance, too.

        * quotearg.c (N_STATIC_SLOTVECS): Define.
        (STATIC_BUF_SIZE): Define.
        (quotearg_n_options): Use only statically allocated storage when
        N < N_STATIC_SLOTVECS and the length of the quoted result is smaller
        than STATIC_BUF_SIZE.

2000-07-29  Jim Meyering  <meyering@lucent.com>

        * diacrit.c (diacrit_diac): Use __MSDOS__ in favor of MSDOS.

2000-07-18  Bruno Haible  <haible@clisp.cons.org>

        * mbswidth.h (mbswidth): Add a flags argument.
        (mbswidth): New declaration.
        (MBSW_ACCEPT_INVALID, MBSW_ACCEPT_UNPRINTABLE): New macros.
        * mbswidth.c (mbswidth): Add a flags argument.
        (mbsnwidth): New function.

2000-07-24  Jim Meyering  <meyering@lucent.com>

        * mbswidth.c: Remove useless #else.  From Bruno Haible.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * mbswidth.c (_XOPEN_SOURCE):
        Don't define; this causes problems on Solaris 7.
        (wcwidth) [!HAVE_DECL_WCWIDTH]: Declare.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c:
        Include <wchar.h> even if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX),
        so that mbstate_t is always defined.

        Do not inspect MB_LEN_MAX, since it's incorrectly defined to
        be 1 in at least one GCC installation, and this configuration
        error is likely to be common.  Ignoring MB_LEN_MAX hurts
        performance on hosts that have mbrtowc but have only unibyte
        locales, but I assume these hosts are rare.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c: Streamline by invoking multibyte code only if needed.
        <wchar.h>: Include only if HAVE_MBRTOWC && 1 < MB_LEN_MAX.
        (MB_CUR_MAX): Redefine to 1 if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX).
        (quotearg_buffer_restyled): If a unibyte locale, don't bother to
        invoke multibyte primitives.

2000-07-23  Jim Meyering  <meyering@lucent.com>

        * basename.c (base_name): Add an assertion.

2000-07-15  Bruno Haible  <clisp.cons.org>

        * quotearg.c: When the system forces us to redefine mbstate_t,
        shadow its mbsinit function.

2000-07-16  Bruno Haible  <haible@clisp.cons.org>

        * mbswidth.h: New file.
        * mbswidth.c: New file.
        * Makefile.am (libfetish_a_SOURCES): Add mbswidth.c.
        (noinst_HEADERS): Add mbswidth.h.

2000-07-17  Bruno Haible  <haible@clisp.cons.org>

        * config.charset: Add support for FreeBSD. Improve support for HP-UX
        and IRIX 6.

2000-07-15  Jim Meyering  <meyering@lucent.com>

        * makepath.c: Include quote.h.
        (make_path): Convert "`%s'" in format strings to "%s", and wrap each
        corresponding argument in a `quote (...)' call.
        Give better diagnostics.

        * Makefile.am (libfetish_a_SOURCES): Add quote.c.
        (noinst_HEADERS): Add quote.h.

        * quote.c (quote, quote_n): New file.  Two functions taken verbatim
        from tar's src/misc.c.
        * quote.h: New file.  Prototypes for same.

2000-07-10  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Bruno Haible.
        * quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition.
        Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT,
        to decide whether to define the BeOS workaround macro;
        this adjusts to the change to AC_MBSTATE_T.

2000-07-13  Paul Eggert  <eggert@twinsun.com>

        * quotearg.h (enum quoting style): New enum clocale_quoting_style.

        * quotearg.c: (quoting_style_args, quoting_style_vals,
        quotearg_buffer_restyled): Add support for
        clocale_quoting_style.  Undo previous change to
        locale_quoting_style behavior, and undo the "{LEFT QUOTATION MARK}"
        and "{RIGHT QUOTATION MARK}" msgids.

2000-07-05  Paul Eggert  <eggert@twinsun.com>

        The old behavior of quoting `like this' doesn't look good with
        newer, ISO-style fonts.  See:
        http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html

        Instead, quote "like this" by default.  Let the translator
        tailor the locale-specific quoting behavior by providing
        translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}.

        * quotearg.c (N_): New macro.
        (gettext_default): New function.
        (quotearg_buffer_restyled): Use
        gettext_default ("{LEFT QUOTATION MARK}", "\"") for left quote, and
        gettext_default ("{RIGHT QUOTATION MARK}", "\"") for right quote.

2000-07-09  Jim Meyering  <meyering@lucent.com>

        * Most files: Update copyright dates to include 2000.

2000-07-08  Jim Meyering  <meyering@lucent.com>

        * xgethostname.c (ENAMETOOLONG): Define to an unlikely value
        if not defined.
        (xgethostname): Remove now-unnecessary #ifdef.
        Move declaration of `err' into loop where it's used.

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * xgethostname.c (xgethostname): Protect against the SunOS5.5 bug
        by allocating a larger buffer. Test the gethostname return value for
        being >= 0, not == 0, for BeOS.  Don't exhaust memory if gethostname
        returns an error and ENAMETOOLONG isn't defined.

2000-07-05  Paul Eggert  <eggert@twinsun.com>
        and Bruno Haible  <haible@clisp.cons.org>

        * quotearg.c (mbrtowc): Declare returned type, since BeOS doesn't.

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * quotearg.c (struct quoting_options): Simplify quote_these_too
        dimension.

2000-07-03  Jim Meyering  <meyering@lucent.com>

        * strndup.c: [!HAVE_DECL_STRNLEN]: Declare strnlen.
        Reported by Bruno Haible.

2000-07-04  Jim Meyering  <meyering@lucent.com>

        * quotearg.c: Make inclusion of <wchar.h> independent of whether
        HAVE_MBRTOWC is set.  Required at least for irix-5.6, which
        lacks mbrtowc.

2000-07-03  Paul Eggert  <eggert@twinsun.com>
        and Bruno Haible  <haible@clisp.cons.org>

        * quotearg.c (mbrtowc):
        Assign to *pwc, and return 1 only if result is nonzero.
        (iswprint): Use ISPRINT when substituting our own mbrtowc.

2000-07-03  Jim Meyering  <meyering@lucent.com>

        * readutmp.h: [HAVE_UTMPX_H]: Include <utmp.h> if HAVE_UTMP_H.
        This is necessary to get a definition of e.g., UTMP_FILE on HP-UX 10.20.
        From Bob Proulx.

2000-07-02  Jim Meyering  <meyering@lucent.com>

        * quotearg.c (mbstate_t): Don't define here.

2000-07-02  Jim Meyering  <meyering@lucent.com>

        * nanosleep.c (SIGCONT): Define if not already defined.

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * mountlist.c: Use MOUNTED_FS_STAT_DEV instead of MOUNTED_NEXT_DEV,
        per change in ../m4/ls-mntd-fs.m4.
        (read_filesystem_list): Ignore symbolic links.

2000-06-29  Jim Meyering  <meyering@lucent.com>

        * same.c: Include <string.h> or <strings.h>, as appropriate,
        for declaration of strcmp.

        * long-options.c: Include <stdlib.h>, for declaration of exit.

        * mountlist.c (fsp_to_string) [HAVE_F_FSTYPENAME_IN_STATFS]:
        Avoid warning by casting result to `char *' to remove `const'.

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * Makefile.am (libfetish_a_SOURCES): Remove readutmp.c.

2000-06-26  Paul Eggert  <eggert@twinsun.com>

        savedir now sets errno on failure and invokes xmalloc to get memory.
        Fix a couple of other minor bugs while we're at it.

        * savedir.c (<unistd.h>): Do not include; there's no need.
        (NAMLEN): Remove macro.
        (malloc, realloc): Remove decls.
        (stpcpy): Likewise.
        ("xalloc.h"): Include.
        (NAME_SIZE_DEFAULT): New macro.
        (savedir): Use xmalloc / xrealloc to allocate memory.
        Use NAME_SIZE_DEFAULT if name_size is negative or overflows to zero.
        Skip "" directory entries.
        Use strlen to calculate directory entry length, since the old method
        is rarely used these days and isn't worth supporting.
        Don't use a pointer after freeing it.
        Check for integer overflow when calculating allocation size.
        Use memcpy to copy entries, instead of stpcpy.
        Set errno properly when returning NULL.
        Check for readdir error.

2000-06-26  Jim Meyering  <meyering@lucent.com>

        * posixtm.c [HAVE_STDLIB_H]: Include stdlib.h, for decl of abort.

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * getusershell.c (xmalloc, xrealloc): Remove functions.
        Include xalloc.h.
        Don't include <stdlib.h>.  Don't declare malloc, realloc.

2000-06-23  Bruno Haible  <haible@clisp.cons.org>

        * unicodeio.c (print_unicode_char): Work around ansi2knr deficiency.

        HAVE_MBRTOWC && HAVE_WCHAR_H && !HAVE_MBSTATE_T_OBJECT.
        (iswprint): Define to 1 if !defined iswprint && !HAVE_ISWPRINT,
        not if ! (HAVE_MBRTOWC && HAVE_WCHAR_H).

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * xgetcwd.c (xgetcwd): If the required pathname length is smaller
        than 1024, return a memory chunk of least possible size, instead
        of size PATH_MAX + 2. In the loop, increment the size proportionally.
        Use free/xmalloc instead of xrealloc to avoid copying for very long
        paths.

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * canon-host.c (canon_host): Use malloc and memcpy to copy an
        address, not strdup.  Include <stdlib.h> and don't declare free().

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * path-concat.c (path_concat): Don't access dir[-1] if dir is
        the empty string.

2000-06-21  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (libfetish_a_SOURCES): Add getstr.c.
        (noinst_HEADERS): Add getstr.h.

        * getline.c (getstr): Move into a separate file.
        * getstr.c (getstr): New file, extracted from getline.c, with
        the following changes: new parameter, delim2; both delim[12]
        parameters have type `int', not `char'.  The latter would lose
        with 8-bit delimiters.
        * getstr.h: New file.

2000-06-19  Jim Meyering  <meyering@lucent.com>

        * getloadavg.c [HAVE_NLIST_H] (NLIST_STRUCT): Define.

2000-06-18  Jim Meyering  <meyering@lucent.com>

        * mkdir.c: Remove file, due mainly to copyright incompatibility.
        Besides, these days every porting target provides a mkdir function.

        * strnlen.c: Include memory.h, string.h, and/or strings.h as needed.
        (this snippet comes from src/system.h).

2000-03-07  Paul Eggert  <eggert@twinsun.com>

        * savedir.c (savedir): Work even if directory size is

        not `#if STDC_HEADERS'.
        Declare malloc if needed.

        * backupfile.c: Use `#if !HAVE_DECL...' instead of `#ifndef HAVE_DECL..'
        now that autoconf always defines the HAVE_DECL_ symbols.
        * human.c: Likewise.
        * same.c: Likewise.
        * strtoumax.c: Likewise.

        * nanosleep.h (nanosleep): Guard declaration with
        `#if ! HAVE_DECL_NANOSLEEP'.
        Without this, OFS gets a redeclaration error for rpl_nanosleep, due to
        the declaration in that vendor's sys/timers.h.
        Reported by Christian Krackowizer.

        * quotearg.c (ISASCII): Add #undef and move definition to follow
        inclusion of wctype.h to work around solaris2.6 namespace pollution.

        Reported by Tom Tromey.

2000-01-30  Jim Meyering  <meyering@lucent.com>

        * readutmp.c (extract_trimmed_name): Use UT_USER instead of hard-coding

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

        (strverscmp): Use ISDIGIT, not isdigit.

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

        * nanosleep.c (nanosleep):
        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).

2000-01-17  Jim Meyering  <meyering@lucent.com>

        * interlock: Remove unused file.  Reported by François Pinard.
