accurate diagnostic when failing to remove a file owned by some other
user. Reported by Ivo Timmermans via Michael Stone.
This fixes Debian bug# 178471.
(print_only_size): Reflect the fact that we're printing byte counts,
not ST_NBLOCKSIZE-byte-block counts.
(print_size): Call print_only_size rather than duplicating its code.
(process_file): Accumulate byte counts, rather than block counts.
listed mount point under `Filesystem'. Before, for an unmounted
block- or character-special file argument, it would display the
command-line argument instead.
(show_disk): Return a value indicating whether
there was a match. Don't try to find a mount point here.
(show_entry): If show_disk doesn't find a match, call show_point.
(du_files): Add prototype with ATTRIBUTE_NORETURN.
Exit from this function, not from...
(main): ...here.
Instead, if possible, invoke du_files through a macro that
runs it with a large, mmap'd stack.
string of spaces matching the length of the English `...Type' header,
output the right number of spaces to match the selected translation.
Reported by Yann Dirson and Jean Charles Delepine as Debian bug 131113.
(bytes_split, lines_split, line_bytes_split): Use full_read,
not safe_read. The way split was using the latter, a short read
could cause split to terminate before EOF.
(bytes_split): Remove unnecessary `else' after break.
(lines_split): Likewise. and correct misleading indentation.
Include euidaccess.h.
(eaccess): Rewrite function to set the real uid and gid temporarily
to the effective uid and gid, then invoke 'access', and then set the
real uid and gid back. On systems that lack setreuid or setregid,
fall back on the kludges in euidaccess. Before, it would not work
for e.g., files with ACLs, files that were marked immutable,
or on file systems mounted read-only.
the name of the file system on which the file resides, usually `/'.
Before, it would leave the `Mounted on' field blank.
(show_disk): Add parameter: STATP.
If we don't find a matching device name, then resort to calling
find_mount_point.
(print_human_type): Remove function.
(human_access): Rename from print_human_access. Return a string.
(human_time): Rename from print_human_time. Return a string.
(print_stat): Arrange so that field width and an alignment specifier
are honored for the %A, %F, %x, %y, and %z formats.
[%F]: Use file_type; this gives slightly different file type strings,
e.g., `directory' instead of `Directory' and `regular file' or
`regular empty file' instead of `Regular file'.
Include "dirname.h", "ftw.h", and "quotearg.h".
(AUTHORS): Add self.
(opt_one_file_system): Move global into `main'.
(path, xstat, exit_status): Remove declarations.
(arg_length, suffix_length): New globals.
(G_fail): New global, sort of like the old `exit_status'.
(IS_FTW_DIR_TYPE): Define.
(print_only_size): New function.
(process_file): New function.
(str_init, ensure_space, str_copyc, str_concatc): Remove functions.
(str_trunc, pop_dir, count_entry): Likewise.
(du_files): Rewrite to use nftw.
store the screen columns, and return the number of bytes instead.
(print_dir): Pass NULL as fourth parameter of quote_name.
(print_name_with_quoting): Likewise.
(length_of_file_name_and_frills): Get the width from the fourth
parameter of quote_name instead of return value.
