All callers changed. + * src/who.c (scan_entries): 0 -> STDIN_FILENO. + * src/whoami.c (main): Print uids using unsigned long int, not + unsigned int. + + * src/unexpand.c: Int cleanup and minor reorganization to be more + like src/expand.c. + Include quote.h, xstrndup.h. + (TAB_STOP_SENTINEL): Increase from INT_MAX to INTMAX_MAX. + (convert_entire_line, have_read_stdin, parse_tabstops, next_file, + unexpand, main): + Use bool for booleans. + (tab_size, tab_list, add_tabstop, validate_tabstops, unexpand): + Use uintmax_t for column counts. + (first_free_tab, validate_tabstops, unexpand): Use size_t for sizes. + (add_tabstop, parse_tabstops, main): Don't reserve UINTMAX_MAX + as a tab stop. + (parse_tabstops): Don't use ISBLANK on possibly-signed char. + Detect overflow in tab stop string. + (next_file, main): Use EXIT_FAILURE/EXIT_SUCCESS instead of 1/0. + (unexpand): Concatenate input files the same way expand does. + + * src/touch.c (no_create, use_ref, posix_date, amtime_now, + touch, main): Use bool for booleans. + (main): Avoid integer overflow when given more than INT_MAX + options. + * src/tsort.c (struct item, n_strings): Use size_t for sizes. + (have_read_stdin, count_items, scan_zeros, detect_loop, + recurse_tree, walk_tree, tsort, main): + Use bool for booleans. + (exit_status): Remove. + (tsort): Return a success flag instead of storing into a global. + (main): Use it. + * src/tty.c (silent, main): Use bool for booleans. + (main): 0 -> STDIN_FILENO. + * src/uname.c (print_element): Use bool for booleans. + + * src/test.c (TRUE, FALSE, SHELL_BOOLEAN, TRUTH_OR, TRUTH_AND): + Remove. All uses replaced by C99 boolean primitives. + (TEST_TRUE, TEST_FALSE): New constants, for readability. + (test_unop, binop, unary_operator, binary_operator, two_arguments, + three_arguments, posixtest, expr, term, and, or, is_int, age_of, + one_argument, main): Use bool for booleans. + (advance, unary_advance): Now inline procedures rather than a macros. + (is_int): Renamed from isint, to avoid namespace clash with ctype.h. + (term, and, or): When it's easy, loop instead of recursing. + (term): Avoid integer overflow if there are INT_MAX-3 args (!). + (binary_operator, unary_operator): Simplify by systematically rewriting + true==FOO to FOO (where FOO is a boolean). + (unary_operator): Don't consider a file to be a regular file + merely because its mode&S_IFMT is zero. Just use S_ISREG. + Remove unnecessary casts. Remove ifdefs for things like + S_ISSOCK that are no longer needed, since stat-macros.h always + defines them now. + + * src/tac-pipe.c (buf_init_from_stdin, find_bol, tac_mem): + Use bool for booleans. + (buf_init_from_stdin, buf_free, find_bol, print_line): + Use size_t for sizes. + * src/tac.c (separator_ends_record, tac_seekable, tac_file, + tac_stdin, tac_stdin_to_mem, main): Use bool for booleans. + (match_length, G_buffer_size, tac_seekable, main): Use size_t for sizes. + (tac_seekable): Use ptrdiff_t for pointer subtraction. + Report an error if the result is out of range. + (tac_seekable, main): Check for integer overflow in buffer size + calculations. + (main): Remove unnecessary casts. + + * src/su.c (run_shell): Pass a new n_additional_args arg, so that + the callee doesn't have to count 'em. All callers changed. + Don't allocate more space for the arg vector than we'll need. + Use memcpy to copy the args rather than rolling our own loop. + 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. + + * src/stty.c (VA_START): Remove.
