to placate HPUX's C compiler. Reported by Bob Proulx.

now that autoconf always defines the HAVE_DECL_ symbols.
|
|
Based on a patch from Adam Klein via Michael Stone.
|
|
(count_entry): Factor out common code (pop_dir), and call the new
function instead.
Move declaration of global, `stat_buf' into this function.
(du_files): Don't stat `.' or call save_cwd, since count_entry
never returns with a changed working directory.

Print the header line only if there is at least one valid argument.

to go along with corrected autoconf test: Reported by G Queri.

a non-directory. Reported by Brian Kimball via Michael Stone.

(O_NONBLOCK): Define to O_NDELAY if not defined.
(touch): Open with O_NONBLOCK, so one can touch a fifo without hanging.

for directories. From H. J. Lu.

[Instead, merely give examples showing how to accomplish the same
task with fewer limitations using existing tools. ]
Suggestion from Bruno Haible.
(valid_format): Rename from check_format.
|
|
back to #ifdef TIOCGWINSZ.
|
|
(screen_columns): Use xstrtol, not atoi.
If get_win_size fails and $COLUMNS == 0, then return 80, not `0'.

exit when it found a loop. Now it continues and outputs all items.
(exit_status): New variable.
(loop): New varibale.
(count_items, scan_zeroes): Change return type to int.
(detect_loop): Complete rewrite to correctly implement detection
of loops. Also change return type to int.
(recurse_tree): Stop if ACTION returns non-zero. This involves
changing the return type of this function and ACTION to int.
(walk_tree): Change return type of ACTION to int.
(tsort): Continue sort after a loop has been detected (and
broken). Set exit_status to 1 if a loop was detected.
(main): Use exit_status to determine exit code.

to `-1' for unsigned int n_files == 0. Doing so lead to a segfault on
alpha. From Michael Stone.

local that is sometimes undeclared.
|
|
[! HAVE_DECL_STRTOULL]: Declare strtoull.
Required for some AIX systems. Reported by Christian Krackowizer.
|
|
|
|
(format_type): New global to take place of intconv.
(DO_printf): New macro.
(main): Use it.
|
|
(intconv): New variable.
(usage): Update.
(main): Call scan_arg instead of scan_double_arg. Call check_format
before scan_arg.
(scan_int_arg, scan_arg): New functions.
(check_format): Add intconv argument. Accept %d, %u, %o, %x, %X.
(print_numbers): If intconv is true, pass an int argument to printf.
|
|
(Filter): Rename from PFL.
(non_neg_strtol): Remove function.
(find_bracketed_repeat): Use xstrtoul instead of non_neg_strtol.
(squeeze_filter, set_initialize, main): Use size_t and ssize_t in
place of long and int in several decls.
(read_and_delete, read_and_xlate): Likewise, and remove assertion.
|
|
(AUTHORS): Add djm.
|
|
|
|
(PFL): Rename from PFI now that it returns long.
(squeeze_filter): Declare as `long': i, nr, out_len.
|
|
(hard_LC_CTYPE): Remove.
(keylist): Renamed from keyhead. Now a pointer, not a
mostly-unused struct. All uses changed.
(findlines, keycompare, CMP_WITH_IGNORE, compare, checkfp, mergefps,
sort): Tune and use a more consistent style for reallocation.
(keycompare, main): Don't worry about LC_CTYPE;
it's buggy with multibyte chars anyway.
(compare): Invoke alloca (0) after each call to keycompare,
not just the ones that return nonzero. This avoids a memory
leak on architectures without builtin alloca that occurs
sometimes when a file contains all duplicate lines.

Don't use SA_INTERRUPT to decide whether to call sigaction, as
POSIX.1 doesn't require SA_INTERRUPT and some systems
(e.g. Solaris 7) don't define it. Use SA_NOCLDSTOP instead;
it's been part of POSIX.1 since day 1 (in 1988).

From Wolfram Kleff.
|
|
(unexpand): Use it instead of INT_MAX.
Declare column and pending to be `unsigned'.
Increment pending and column counters only if column is smaller
than TAB_STOP_SENTINEL.
|
|
Also, stop worrying about ancient memchr bug (misbehavior when
size is zero), since other code doesn't worry either.
|
|
(main): Likewise, for add_exclude_file.
|
|
`--backup --verbose' as cp, mv, install. Before this, the backup
file name wasn't printed at all.
|
|
(copy_internal): When making backup files in verbose
mode, print the backup file name on the same line as the rest of the
information, e.g., `a -> b (backup: b.~13~)' rather than on a line
by itself.
|
|
`CHAR_MAX + n'.

(clock_get_realtime): Return argument, for convenience.
(main): Use this to simplify main sleep loop.

(AUTHORS): Add Paul Eggert.
