downloadcoreutils-0e3b87195ab0820d228cda986ac916d52b696aff.tar.xz
Fix bug where chmod, chown, and chgrp did not process operands
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.
