2008-06-16remove redundant const directivesJim Meyering
In 1463824d8e7f72c31f1d803d7cfe2b608ccafc5c, I added some missing "const" directives, as well as some new, redundant ones. This removes the redundant ones. Pointed out by Eric Blake. * base64.c, cat.c, chcon.c, chgrp.c, chmod.c, chown.c, comm.c: * cp.c, csplit.c, cut.c, date.c, dd.c, df.c, dircolors.c, du.c: * env.c, expand.c, fmt.c, fold.c, groups.c, head.c, id.c: * install.c, join.c, kill.c, ln.c, ls.c, md5sum.c, mkdir.c: * mkfifo.c, mknod.c, mktemp.c, mv.c, nice.c, nl.c, od.c: * paste.c, pathchk.c, pinky.c, pr.c, ptx.c, readlink.c, rm.c: * rmdir.c, runcon.c, seq.c, shred.c, shuf.c, sort.c, split.c: * stat.c, stty.c, su.c, sum.c, tac.c, tail.c, tee.c, timeout.c: * touch.c, tr.c, truncate.c, tty.c, uname.c, unexpand.c, uniq.c: * wc.c, who.c: Remove redundant const directives. * maint.mk (sc_const_long_option): Don't require redundant "const".

2006-07-21* src/su.c (usage): Correct typo in --help output: s/commmand/command/Jim Meyering
Reported by Tim Waugh. Also remove the comment duplicating much of --help output.
2006-03-26(log_su, run_shell): Use new last_component, in place of base_name.Jim Meyering
2005-08-23Remove unnecessary parens in `#if defined (SYMBOL)' expressions.Jim Meyering

2005-05-14Update FSF postal mail address.Jim Meyering
2004-08-03(run_shell): Pass a new n_additional_args arg, so thatPaul Eggert
the callee doesn't have to count 'em. All callers changed. Don't allocate more space for the arg vector than we'll need. Use memcpy to copy the args rather than rolling our own loop. Use size_t for sizes. (fast_startup, simulate_login, change_environment, log_su, correct_password, restricted_shell, main): Use bool for booleans. (longopts): Don't assume change_environment is an int. Use NULL, not 0, for pointers. (xsetenv): New function, replacing xputenv and concat. All callers changed. (elements): Remove; no longer needed. (log_su, correct_passwd, main): Prefer !x to x==NULL. (log_su): 2 -> STDERR_FILENO. (modify_environment, main): Don't assume that getenv's returned value has an indefinite lifetime. (modify_environment): Allocate a larger environ. (main): Remove an impossible 'case 0'; if it happens now, it'll get diagnosed. Don't assume getpwnam results outlive endpwent. Check for null or empty pw_name, pw_dir and for null pw_passwd.
2004-06-01(correct_password, restricted_shell, main):Jim Meyering
Prefer the notation `STREQ (a, b)' over `strcmp (a, b) == 0'.
2004-01-22(usage): Use EXIT_SUCCESS, not 0, for clarity.Jim Meyering
(main): Initialize exit_failure to EXIT_FAIL. (main): Use EXIT_ENOENT and EXIT_CANNOT_INVOKE rather than roll-your-own symbols or integers.
2003-10-18Most .c files (AUTHORS): Revert the WRITTEN_BY/AUTHORS changeJim Meyering
of 2003-09-19. Now, AUTHORS is a comma-separated list of strings. Update the call to parse_long_options so that `AUTHORS, NULL' are the last parameters. * src/true.c (main): Append NULL to version_etc argument list. * src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.
2003-09-18(WRITTEN_BY): Rename from AUTHORS.Jim Meyering
Begin each WRITTEN_BY string with `Written by ' and end it with `.'. Mark each WRITTEN_BY string as translatable.
2003-07-23Don't include headers already included by system.h:Jim Meyering
Don't include closeout.h.
2003-07-18(usage): Don't call close_stdout here.Jim Meyering
(main): Use close_stdout via atexit. Now `su --version > /dev/full' fails, as it should. Somehow, the change of 2000-05-07 that purports to fix this was not checked in.
2003-06-17(main): Call initialize_main.Jim Meyering
2003-04-11Remove anachronistic casts of xmalloc,Jim Meyering
xrealloc, and xcalloc return values and of xrealloc's first argument.
2002-08-31Change `exit (0)' to `exit (EXIT_SUCCESS)',Jim Meyering
`exit (1)' to `exit (EXIT_FAILURE)', and `usage (1)' to `usage (EXIT_FAILURE)'.
2002-08-30Change `error (1, ...' to `error (EXIT_FAILURE, ...'.Jim Meyering
2002-08-01(run_shell): Exit with status 126 or 127 when execvp orJim Meyering
execv fails, for consistency with POSIX commands like env and nice.
2002-07-02(usage): Use the PACKAGE_BUGREPORT e-mail address, rather than hard-coding it.Jim Meyering
2001-12-15Use new macros, HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTIONJim Meyering
instead of hard-coding --help and --version descriptions. Split --help output into smaller pieces. Use fputs, not printf.
2001-08-14(xputenv): Remove parameter's const qualifier.Jim Meyering
2001-05-12Include "dirname.h".Jim Meyering
(base_name): Remove decl; now in dirname.h.
2001-01-07back out last, prematurely-committed, changeJim Meyering
2001-01-07Correct the indentation of an `#endif'.Jim Meyering
2000-08-07(xputenv): Invoke xalloc_die instead of printing our own message.Jim Meyering
2000-07-23Include <sys/param.h> if HAVE_SYS_PARAM_H is defined,Jim Meyering
rather than if _POSIX_VERSION is defined. Remove declarations of getpwuid, getgrgid, and getuid, now that they're in sys2.h.
2000-05-07Include "closeout.h".Jim Meyering
(main): Call atexit with close_stdout.
2000-02-09(correct_password): Correct HAVE_STRUCT_* name in #if guardJim Meyering
to go along with corrected autoconf test: Reported by G Queri.
2000-01-30(correct_password): Guard with `HAVE_GETSPNAM && HAVE_STRUCT_PASSWD_SP_PWDP',Jim Meyering
rather than just `#ifdef HAVE_SHADOW_H'.

1999-08-30split a long line.Jim Meyering
1999-08-22(run_shell): Declare with noreturn attribute.Jim Meyering
Use an explicit exit(1) rather than doing that through error.
1999-03-31No longer include long-options.h.Jim Meyering
[long_options]: Add entries for --help and --version. Remove parse_long_options call. (main) [getopt switch]: Add a case for each of --help and --version.
1999-03-31(PROGRAM_NAME, AUTHORS): Define and use.Jim Meyering
1999-03-06Include long-options.h.Jim Meyering
[long_options]: Remove the "help" and "version" entries. Remove declarations of show_help and show_version. (main): Use parse_long_options, including author name(s). Remove the show_version and show_help blocks.
