and not readable. Prefer write access, since this should work
better with fdatasync.
|
|
(fts_open, fts_read, fts_children, fts_safe_changedir):
Use it, so that the code works even if the directory
is writeable but not readable.

(cu_PREREQ_STAT_PROG): Use the _ONCE variants when appropriate.
Include sys/param.h before testing for sys/mount.h.
|
|
(gl_LIST_MOUNTED_FILE_SYSTEMS): Include sys/param.h before
testing for sys/mount.h.
|
|
(gl_MACROS): Use the _ONCE variants when appropriate.
Include sys/param.h before testing for sys/sysctl.h and sys/mount.h;
needed for OpenBSD 3.4.
|
|
(gl_FSUSAGE): Include sys/param.h before checking for sys/mount.h.
Needed for OpenBSD 3.4.
|
|
(GNULIB_BOOT_TIME): Include sys/param.h before testing
for sys/sysctl.h; needed for OpenBSD 3.4.
|
|
Define to a concatenation of string literals, not to an expression;
needed for concatenation contexts.
(INTMAX_MAX, INTMAX_MIN): New macros.

a collision on OpenBSD 3.4.

unsigned long; this isn't true for st_ino on Solaris 9.
|
|
(PRIuMAX) [!PRI_MACROS_BROKEN && !defined PRIuMAX]: New macro.
(find_matching_ancestor): Use it for dev_t and ino_t.

sometimes returns a positive errno value even when it succeeds.
(print_errno_message) [!LIBC]: Fall back on strerror if
__strerror_r fails.

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:

(print_lines, print_words, print_chars, print_bytes, print_linelength,
have_read_stdin, wc, wc_file, main):
Use bool for booleans.
(exit_status): Remove.
(wc, wc_file): Return bool status. All callers changed.
|
|
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.
|
|
|
|
(main): 0 -> STDIN_FILENO.
|
|
(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.
|
|
touch, main): Use bool for booleans.
(main): Avoid integer overflow when given more than INT_MAX
options.

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.
|
|
Use bool for booleans.
(buf_init_from_stdin, buf_free, find_bol, print_line):
Use size_t for sizes.
