(COMMON_SHORT_OPTIONS): Add -B, -D, -e, -F, -H, -I, -L, -O, -s, -X.
(long_options, main): --strings is now -S, not -s.
(usage): Reflect the usage changes.
(parse_old_offset): Do not issue a diagnostic on failure;
callers now do this as necessary.
(main): Support POSIX syntax. Remove unused case 0 from getopt_long.
Add support for new short options (many undocumented) for
compatibility with FreeBSD. Remove FIXME for -s; it's now
POSIX-compatible. Default format is now oS, not o2.
(bit_count): Remove. All uses changed to....
(multiple_bits_set): New function.
(scanargs): Use it, and check separately for each set of
incompatible options, to improve diagnostics.
(MX): Remove.
(apply_translations): Move checks for incompatible options
to scanargs, so that they're done consistently.
(write_error, xputchar): New functions.
(paste_parallel): Use correct errno value after input error.
(paste_parallel, paste_serial): Report errno value after output error.
(parse_tab_stop): Renamed from parse_tabstop. All uses changed.
(validate_tab_stop): Renamed from validate_tabstop. All uses changed.
(next_file, main): Check fclose against 0, not EOF.
(unexpand): Remove unnecessary casts.
Add another loop nesting level, for lines, so that per-line variables
are initialized cleanly.
Revamp tab checking. Check for write error immediately, rather
than just once at the end of the program.
(TAB_STOP_SENTINEL): Remove.
(tab_size): Now size_t, not uintmax_t, since we need to store
the sequences of blanks.
(max_column_width): New var.
(usage): Say "blank" where POSIX requires this.
(add_tab_stop): Calculate maximum column width.
(unexpand): Store the pending blanks, instead of merely counting them.
Follow POSIX's rules about -a requiring two blanks before a tab stop.
Get rid of internal label and goto.
(usage): -i does not convert tabs after non-tabs.
(add_tab_stop): Renamed from add_tabstop. All uses changed.
(parse_tab_stop): Renamed from parse_tabstop. All uses changed.
(validate_tab_stop): Renamed from validate_tabstop. All uses changed.
(next_file, main): Check fclose against 0, not EOF.
(expand): Remove unnecessary casts.
Add another loop nesting level, for lines, so that per-line variables
are initialized cleanly.
Revamp tab checking. Check for write error immediately, rather
than just once at the end of the program.
a destination with link count greater than one. This is so
that commands like "cp -a" don't get confused when copying into
a destination that already contains many hard links.
whether to include files. Include <sys/param.h> if
HAVE_SYS_PARAM_H (not HAVE_SYSCTL).
(main) [defined __POWERPC__]: Add a kludge to work around a
Mac OS X bug, so that uname -p defaults to "powerpc" if
sysctl ((int[]) {CTL_HW, HW_MACHINE_ARCH}, 2, buffer, &bufsize, 0, 0)
fails. Problem reported by Petter Reinholdtsen in:
http://lists.gnu.org/archive/html/bug-gnu-utils/2003-02/msg00201.html
main): Use bool for booleans.
(writeline, check_file): Use uintmax_t for line counts.
(check_file): Check for and report line number overflow,
when that matters.
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.
(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.
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.
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.
