Sat Feb 19 14:23:14 1994  Jim Meyering  ([e-mail])

    * Version 1.9.4.

    * stty.c (main): Use getopt_long_only with "ag" instead of
    getopt_long with "".  The latter incremented optind so the
    -a and -g options weren't recognized.

    * Version 1.9.3.

Tue Feb 15 18:28:28 1994  Jim Meyering  ([e-mail])

    * stty.c (main): Use getopt only to recognize long options.
    Hand code the loop to detect -a, -g, -ag and -ga.  Using getopt
    to detect the short options loses (because we have to ignore
    unrecognized options and we are allowing GNU getopt to permute)
    because e.g. `-tabs' is interpreted as a group of options, one of
    which is `-a'.  Before, running `stty -tabs echo' gave this error:
      stty: when specifying an output style, modes may not be set
    Reported by Arne H. Juul.

Sun Feb 13 13:34:25 1994  Jim Meyering  ([e-mail])

    * basename.1, dirname.1, stty.1: Reflect usage changes.
    * basename.c, dirname.c, stty.c (usage): Ditto.

    * long-options.h (parse_long_options): Invoke usage function
    argument with explicit dereference as per GNU coding standards.

    * basename.c dirname.c: Use parse_long_options instead of the
    conventional getopt_long paradigm.  Before, the commands
    `basename file-dist -dist' and `basename -- file.c .c' produced
    incorrect results.  Now, even `basename -file-dist -dist' works
    and the command `basename -- file.c .c' fails for the right
    reason: the `--' is not a special (to getopt) token for these
    commands.  It is interpreted as the filename, so there are too
    many arguments to basename.  Rick Sladkey <[e-mail]>
    reported the problem with basename.

    * stty.c (set_window_size): When stty fails to get the window size
    (as happens on telnet sessions to Solaris systems), initialize all
    fields of the winsize struct.  Before, it was using the uninitialized
    pixel fields of the struct in the ioctl to set window size parameters.
    From Rick Sladkey.

    * stty.c (main): Use parse_long_options to handle --help and --version.
    (main): In the remaining getopt_long loop, don't jump out of the
    loop from the `default' branch of the switch statement.  Doing that
    left optind in an inconsistent when there were non-option arguments
    preceding `reversed' arguments (e.g. stty echo -echoe) and the
    preceding non-option arguments were ignored.  Rick Sladkey reported
    that stty was ignoring arguments.

    * stty.c (main): Fail with a diagnostic when both -g and -a are given.
    (main): Fail with a diagnostic when either -g or -a is used with
    arguments for setting modes.

Fri Feb 11 19:39:37 1994  Jim Meyering  ([e-mail])

    * stty.c (get_win_size): Don't use an ANSI-style function
    definition.  From Kaveh R. Ghazi <[e-mail]>.

Thu Feb 10 01:22:37 1994  Jim Meyering  ([e-mail])

    * stty.c [CSWTCH] (__sparc__ && __svr4__): Define `swtch' to
    _POSIX_VDISABLE by default.  Otherwise, the default settings on
    SunOS 5.3 (from /usr/include/sys/termios.h) have both `swtch'
    and `susp' set to ^Z.  Those default settings are not unusual.
    What is unusual is that with such settings on SunOS 5.3, the tty
    driver doesn't generate a signal for control-Z.  Reported by
    Brent Wiese <[e-mail]>.

    * stty.c (main) [CIBAUD]: Don't report an error on SunOS 4.1.x
    systems if the only difference is in this nybble of c_cflag.
    See the comments for the gory details.  Thanks to
    Erez "HWank1" Zadok <[e-mail]> for reporting this
    and helping me reproduce it.

Tue Feb 01 00:59:56 1994  Jim Meyering  ([e-mail])

    * stty.c (main): Call tcsetattr only if we've updated tty modes,
    not e.g. if we've changed the window size.

    * Update Copyright dates in src/*.

Fri Jan 28 11:02:21 1994  Jim Meyering  ([e-mail])

    * configure.in: Don't set LDFLAGS since linking now uses both
    LDFLAGS and CFLAGS.

Wed Jan 26 10:54:02 1994  Jim Meyering  ([e-mail])

    * stty.c (get_win_size): New function.  Try getting size first
    for the device on stdout.  Try stdin only if that fails.  Suggested
    by Andreas Schwab <[e-mail]>.
    (set_win_size): Call get_win_size instead of calling ioctl directly.
    (display_window_size): Ditto.
    (screen_columns): Ditto.

Mon Jan 24 22:57:18 1994  Jim Meyering  ([e-mail])

    * stty.c (set_window_size): Work around SunOS 4.x kernel bug that
    makes `stty rows 34 cols 80;stty rows 0;stty cols 0' incorrectly
    set rows to 80 and columns to 0.  Sun's stty has this problem, too.
    The kernel bug is fixed in Solaris 2.  Mostly from Alexander Dupuy
    <[e-mail]>.

    * src/Makefile.in: Use both LDFLAGS and CFLAGS when linking.
    * man/Makefile.in: Use binprefix as the default manprefix.

    * nohup.sh: Redirect usage message to stderr.
    From Andreas Schwab <[e-mail]>.

Thu Jan 13 17:27:38 1994  Jim Meyering  ([e-mail])

    * src/Makefile.in: Change all link commands to use both $(CFLAGS)
    and $(LDFLAGS).

Mon Jan 10 01:20:38 1994  Jim Meyering  ([e-mail])

    * man/Makefile.in (manprefix): Use binprefix as the default.

Thu Jan 06 18:19:06 1994  Jim Meyering  ([e-mail])

    * who.c (print_entry): Prepend `/dev/' only if ut_line is not
    already an absolute filename.  Just to be safe.

Fri Dec 31 00:22:59 1993  Jim Meyering  ([e-mail])

    * date.c (usage): Reorder listing of % formats in `sort -f' order.

Tue Dec 28 15:49:32 1993  Jim Meyering  ([e-mail])

    * install.sh: New file.
    Makefile.in [DISTFILES]: Add it.

    * who.c (read_utmp): Use stdio functions instead of open/read/close
    to avoid having to handle POSIX read's -1/errno=EINTR failure case.

    * tee.c (tee): A POSIX implementation of the read system call
    may return -1 and set errno to EINTR when it is interrupted.
    Retry instead of failing with an error.
    (tee): Don't use xwrite.  Use full_write instead and include the
    losing file name in the message reporting a write failure.
    Don't treat standard output as a special case, so a failed write
    to stdout doesn't exit immediately.

    * date.c (usage): Note that for %w, 0 corresponds to Sunday.

Sat Dec 25 23:15:58 1993  Jim Meyering  ([e-mail])

    * who.c (main): Don't chdir ("/dev") for the stat in print_entry.
    (print_entry): Instead of stat'ing the /dev-relative path, ut_line,
    stat the absolute path with "/dev/" prefix.  From David MacKenzie.

Wed Dec 22 00:53:51 1993  Jim Meyering  ([e-mail])

    * expr.c (toarith): Interpret the empty string as just that
    rather than as the integer zero.
    Before, `expr "" == 0' output 1.  Now it prints 0.

    * configure.in (AC_HAVE_HEADERS): Check for float.h for strtod.c.

    * configure.in (check for TIOCGWINSZ): Don't look in sys/ioctl.h
    or sys/ptem.h if we've already found it in termios.h.  This
    eliminates redefinition warnings from including both termios.h
    and sys/ioctl.h on sytems running SunOS.  From Matthew Seaman
    ([e-mail]).

    * date.1: Document new %s format and old `-' and `_' numeric field
    modifiers.

    * memcmp.c: Use the latest version from GNU C library.

Mon Dec 20 23:29:30 1993  Jim Meyering  ([e-mail])

    * configure.in [test for 8-bit clean memcmp]: Add a test to detect
    losing memcmp from SunOS4.1.x.

Sat Dec 18 01:12:24 1993  Jim Meyering  ([e-mail])

    * configure.in (AC_OUTPUT): Put `touch stamp-config' in second arg
    so it goes in config.status.  This eliminates unnecessary second run
    of configure.

Fri Dec 10 01:06:28 1993  Jim Meyering  ([e-mail])

    * stty.c (screen_columns): Instead of dying just because Solaris'
    `ioctl (0, TIOCGWINSZ' fails (strangely only for telnet sessions,
    not rlogin sessions), ignore its errno == EINVAL and try to get
    the number of columns another way.

    * stty.c (set_window_size): If ioctl to get window size fails,
    (as on telnet sessions to Solaris 2.[12] systems) try to set the
    requested fields anyway, setting to zero any unspecified fields.
    This is what Sun's /bin/stty appears to do.
    * (display_window_size): Don't display anything for the number
    of rows and columns if the ioctl call intended to get them fails.

Tue Nov 30 23:58:54 1993  Jim Meyering  ([e-mail])

    * Version 1.9.2.

Mon Nov 29 00:28:35 1993  Jim Meyering  ([e-mail])

    * stty.c, configure.in, acconfig.h: Revert change of Nov 26.
    I am no longer able to reproduce the behavior that prompted
    that patch -- but I had tested only using an old version of gcc.
    When building with a more recent version of gcc or with /bin/cc
    there is no problem.

Sat Nov 27 15:11:21 1993  Jim Meyering  ([e-mail])

    * nice.c (main): If an adjustment is specified, but no command is
    given, give a diagnostic in addition to the usage message.
    (isinteger): Accept a leading `+'.

Fri Nov 26 18:49:42 1993  Jim Meyering  ([e-mail])

    * stty.c [GWINSZ_BROKEN]: Define TIOCGWINSZ to TCGETS for Solaris-2.2.
    On that system, ioctl (0, TIOCGWINSZ, &win) always fails, but using
    TCGETS works.  Reported by Francois Pinard.

    * configure.in [GWINSZ_BROKEN]: New test to detect Solaris' inability
    to get window size from ioctl using TIOCGWINSZ.
    * acconfig.h [GWINSZ_BROKEN]: Add an #undef.

Mon Nov 22 23:40:21 1993  Jim Meyering  ([e-mail])

    * who.c [defined (UTMPX_FILE)]: (undef and) define UTMP_FILE to
    this value even if UTMP_FILE is already defined.  Because some
    systems define both symbols.  From Arne H. Juul.
    * [MESG_BIT]: Rename to S_IWGRP (from sys/stat.h>) and define only
    if not already defined.

Fri Nov 19 23:08:03 1993  Jim Meyering  ([e-mail])

    * who.c (print_entry): Produce reasonably formatted output even when
    sizeof (this->ut_name,ut_line) are much larger than 8.  For Solaris
    and other SysVr4.  With help from Arne H. Juul.
    * configure.in (HAVE_UTMPX_H): New test; combined with test for the
    ut_host field.  From Arne H. Juul.

    * memcmp.c: New file.
    * lib/Makefile.in [SOURCES]: Add memcmp.c.
    * configure.in (AC_REPLACE_FUNCS): Add memcmp.
    Add test for 8-bit clean memcmp.

    * configure.in (AC_HAVE_FUNCS): Add isascii.
    * expr.c [!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 ([e-mail]).
    * printf.c: Ditto.

    * configure.in (AC_HAVE_HEADERS): Add sys/timeb.h; getdate.y tests
    HAVE_SYS_TIMEB_H.

    * stty.c (main): Detect the case in which POSIX-conformant tcsetattr
    fails and still returns zero.

Wed Nov 17 21:05:10 1993  Jim Meyering  ([e-mail])

    * yes.c (main): Complete my half-finished Nov 2 change.
    yes with arguments did not print newlines.  From Andreas Schwab
    (ls5.informatik.uni-dortmund.de).

    * stty.c (wrapf): Fix off-by-one error that could make `stty -a'
    output lines one character too long.  From Andreas Schwab.

Sat Nov 13 00:11:19 1993  Jim Meyering  ([e-mail])

    * Version 1.9.1.

    * configure.in [LIBS]: Add -lbsd if that is necessary to get the
    syslog function.  With help from Kaveh Ghazi.

    * configure.in [LIBS]: Reorganize/unify the code that adds libraries
    solely to resolve syslog.  Add a library only if it is required to
    resolve the syslog reference.

    * configure.in [AC_HAVE_HEADERS]: Check for sys/timeb.h.
    getdate.y needs to know.
    [LIBS]: Check for initgroups in -los.  This is required by SCO-ODT-3.0
    when linking su.
    [LIBS]: Check -lufc for crypt.
    Reported by Steven W Orr ([e-mail]).

Thu Nov 11 23:55:48 1993  Jim Meyering  ([e-mail])

    * id.c [NGROUPS_MAX]: Undefine before redefining.
    From Kaveh R. Ghazi ([e-mail]).

    * who.c (list_entries): Trim any trailing blanks from ut_name
    and make sure the string is NUL-terminated before printing it.
    Before, `who -q' displayed 8-character names with a tty
    (e.g. `q1') suffix.

    * stty.c [CFLUSHO]: Move this definition so it follows the
    one for VFLUSHO.

Mon Nov 08 23:16:36 1993  Jim Meyering  ([e-mail])

    * Version 1.9.

    * su.c (correct_password): Report an error and fail if getpass
    returns NULL.

Tue Nov 02 01:14:21 1993  Jim Meyering  ([e-mail])

    * acconfig.h: Add comments.

    * printenv.c (main): Exit with status == 2 for file error.

    * yes.c (main): Restore argv/optind handling -- now that
    parse_long_options doesn't change optind.

Mon Oct 25 19:22:58 1993  Jim Meyering  ([e-mail])

    * basename.c, date.c, dirname.c, echo.c, env.c, expr.c, id.c,
    logname.c, nice.c, pathchk.c, printenv.c, printf.c, sleep.c,
    stty.c, su.c, tee.c, test.c, tty.c, uname.c, who.c, whoami.c,
    yes.c: Use the preferred `--longopt=arg' syntax in --help message
    rather than `--longopt arg'.  From Francois Pinard.

    * stty.c (main, integer_arg): Don't just call error(1,... about
    improper usage.  Call `error (0,...' then usage (1).

Sun Oct 24 14:10:23 1993  Jim Meyering  ([e-mail])

    * test.c [member]: Don't try to cast index return value to an int.
    That can lose on systems with 64-bit pointers.

    * long-options.c: Save and restore optind, too.
    * long-options.h: New file.
    * long-options.c, echo.c, expr.c, printf.c, test.c, yes.c:
    Include it instead of duplicating dcls.
    * src/Makefile.in: Add dependencies for it.

Tue Oct 19 00:26:27 1993  Jim Meyering  ([e-mail])

    * expr.c [!__STDC__]: Don't define away `const'.  configure alone
    decides whether to do that.  From Francois Pinard.

Sat Oct 16 22:32:54 1993  Jim Meyering  ([e-mail])

    * whoami.c (main): Cast printf arg UID so it matches the type
    expected by %u format no matter how uid_t is defined.

    * stty.c: Accept `status' option and VDISCARD as an alias for
    VFLUSHO.  From Arne H. Juul ([e-mail]).

    * basename.c, date.c, dirname.c, echo.c, env.c, expr.c,
    false.sh, groups.sh, id.c, logname.c, long-options.c, nice.c,
    nohup.sh, pathchk.c, printenv.c, printf.c, sleep.c, stty.c,
    su.c, tee.c, test.c, true.sh, tty.c, uname.c, who.c, whoami.c,
    yes.c: Using --help gets long well- formatted help.  Now --help
    writes to stdout and exits successfully.  From Francois Pinard
    <[e-mail]>.

Wed Oct 13 13:10:27 1993  Jim Meyering  ([e-mail])

    * long-options.c: Include sys/types before system.h.
    From Franc,ois Pinard ([e-mail]).

Tue Oct 12 00:53:26 1993  Jim Meyering  ([e-mail])

    * stime.c [HAVE_CONFIG_H, CONFIG_BROKETS]: Include <config.h>
    or "config.h".

    * src/Makefile.in [clean]: Also delete '['.

Sun Oct 10 14:05:23 1993  Jim Meyering  [e-mail]

    * false.sh, groups.sh, nohup.sh, true.sh: Add --help and --version.
    * src/Makefile.in (false, groups, nohup, true): Substitute the string
    from version.c for @VERSION@ in *.sh.

Sat Oct  9 23:12:53 1993  Jim Meyering  [e-mail]

    * configure.in: Remove AC_UNISTD_H; add unistd.h to AC_HAVE_HEADERS.

Tue Oct  5 22:18:05 1993  Jim Meyering  [e-mail]

    * tty.c (main): Detect write error.  Use isatty (rather than
    testing whether ttyname() is NULL) to determine exit status
    because ttyname may return NULL when stdin is a terminal device.

    * expr.c (eval7): Rewrite if-else-if-else... sequence to avoid a
    spurious `function returns without a value' warning.

    * printenv.c (main), tty.c (main): Detect and report write errors.

    * echo.c, patchchk.c, printenv.c, printf.c, sleep.c, stty.c, su.c,
    tee.c, test.c, tty.c, uname.c, yes.c: Accept --help and --version
    options.

    * long-options.c: New file.  To let echo, expr, printf, test, and
    yes accept --help and --version as unobtrusively as possible.
    * src/Makefile.in [SORUCES]: Add it.

    * configure.in: Add AC_TIME_WITH_SYS_TIME and AC_STAT_MACROS_BROKEN.

    * nice.c (main) [NICE_PRIORITY]: When given an argument, don't
    try to get current priority.  nice() requires only the delta;
    we don't need to compute the absolute priority as for setpriority.

Mon Oct 04 22:15:07 1993  Jim Meyering ([e-mail])

    * who.c (print_entry, print_heading, who_am_i):
    Cast printf field width arguments to int to avoid warnings.
    (idle_string): Cast idle seconds and minutes to int.
    Declare functions read_utmp and idle_string to be static.
    Don't declare ttyname as static.

    * echo.c (just_echo): Use putchar instead of printf.

    * expr.c (parse_long_options): New function.
    (main): Use it to handle --version and --help properly.

    * tee.c (main): Put entire #ifdef inside if-braces to make structure
    clearer.
    (main, tee): Compare close() != 0 rather than close () == -1.

    * pathchk.c (portable_chars_only, dir_ok): Make a couple variables
    const.

Wed Sep 08 00:07:36 1993  Jim Meyering ([e-mail])

    * test.c [advance, unary_advance]: Rewrite using do{...}while(0)
    paradigm instead of comma expressions that make Alpha OSFv1.3
    C compiler segfault.

    * basename.c, date.c, dirname.c, env.c, id.c, logname.c, nice.c:
    Add --help and --version options.

Sat Jul 24 08:52:18 1993  Jim Meyering ([e-mail])

    * configure.in: Check for -lshadow.  Linux needs it when using shadow
    passwords.  Reported by Mattias Olofsson <[e-mail]>.

Thu May 27 20:05:50 1993  Roland McGrath  ([e-mail])

    * configure.in (c_line test): Add missing `fi'.

Tue May 18 23:49:26 1993  Jim Meyering ([e-mail])

    * mkinstalldirs: New file.
    * Makefile.in (installdirs): Use it.

Thu May 13 01:03:16 1993  Jim Meyering ([e-mail])

    * Makefile.in (installdirs): New rules for creating installation
    directories. (install): depend on it.

Mon May  3 22:09:24 1993  Jim Meyering ([e-mail])

    * configure.in: Add AC_GETGROUPS_T.
    * id.c, test.c: Don't define GETGROUPS_T.  Now configure does it.

Sun May  2 00:21:05 1993  Jim Meyering  ([e-mail])

    * expr.c (eval6): Terminate result with a zero byte.
    The command `expr substr xx 1 2' would fail on systems with
    tight malloc.  From Steve James <[e-mail]>.

    * expr.c (null): Recognize the string `0' as zero.
    (divide, mod): Upon request to divide by zero, give an error
    message instead of dumping core.
    From J.T. Conklin <[e-mail]>.

    * configure.in: Check for sys/time.h; getdate.y needs it for
    structs timeval and timezone on some systems.
    * Check for gettimeofday and for `struct tm'.
    * Add existence tests for memcpy and bcopy.

    * configure.in: Find a parser generator.

    * putenv.c: Include stdlib.h only if __GNU_LIBRARY__ is defined.
    Many vendor-supplied <stdlib.h> have a declaration of putenv that
    conflicts with ours.

Tue Apr 20 02:33:24 1993  David J. MacKenzie  ([e-mail])

    * stty.c: Use GWINSZ_IN_SYS_IOCTL, not _AIX, to determine
    whether sys/ioctl.h is needed to support `stty size'.

Thu Apr  1 18:03:47 1993  Jim Meyering  ([e-mail])

    * printf.c, expr.c [isascii]: Undefine before redefining.

Sun Mar 28 00:07:45 1993  Jim Meyering  ([e-mail])

    * stty.c: Accept `flush' option.  From Arne H. Juul [e-mail]
    * system.h: Don't define r?index, bcopy... if they're already defined.

Thu Mar 25 22:41:01 1993  Jim Meyering  ([e-mail])

    * configure.in: Add AC_IRIX_SUN to get -lsun because
    Irix-4.0.5's libc.a doesn't have yp/NIS entrypoints.
    From Kjetil Wiekhorst J|rgensen <[e-mail]>.

Fri Mar 05 00:02:53 1993  Jim Meyering  ([e-mail])

    * date.c: Add long-named options.

Sun Dec  6 23:17:09 1992  Jim Meyering  ([e-mail])

    * date.c: Remove unused definition of isdigit.
    * expr.c (toarith): Change single use of isdigit to ISDIGIT.
    * printf.c (print_formatted, print_esc): Define ISDIGIT and
    ISXDIGIT and use them instead of isdigit and isxdigit.

Wed Dec  2 12:49:11 1992  Jim Meyering  ([e-mail])

    * env.c, id.c, nice.c, pathchk.c, stty.c, su.c, tee.c, tty.c,
    uname.c, who.c: Convert static declarations of struct option
    to use new macros from getopt.h: no_argument, required_argument,
    and optional_argument.

Tue Nov 24 09:46:02 1992  David J. MacKenzie  ([e-mail])

    * echo.c: Use V9_DEFAULT instead of USG.  Define it always.
