left-to-right in some cases.
* src/chmod.c (wd_errno): New var.
(chmod_file): New function, with most of the contents of the
old prcess_file function.
(process_files): Use it. This gives file names to fts one
at a time, so that they are processed left-to-right as POSIX
requires.
* src/chown-core.c (wd_errno, chown_files): Likewise.
(chown_file): New function.
* tests/install/basic-1: Redo test so as to not workaround
the chmod bug, thereby testing for it.
* bootstrap.conf (gnulib_modules): Add savewd.
* src/install.c: Include savewd.h.
(process_dir): New function.
(main, install_file_in_file_parents): Use it, along with the new
savewd module, to avoid some race conditions.
* src/mkdir.c: Include savewd.h.
(struct mkdir_options): New members make_ancestor_function, mode,
mode_bits.
(make_ancestor): Return 1 if the resulting directory is not readable.
(process_dir): New function.
(main): Use it, along with new savewd module, to avoid some
race conditions. Fill in new slots of struct mkdir_options, so
that callees get the values.
* tests/install/basic-1: Test for coreutils 5.97 bug that was
fixed in coreutils 6.0, and which should still be fixed with
this change.
* tests/mkdir/p-3: Likewise.
`(exit N); exit N'. Otherwise, those many tests could exit with
improper exit status when exiting via e.g., a trapped interrupt.
Thanks to a report from Bob Proulx.
