Subject: cp: don't mishandle existing dir dest permissions (Bug#9170)
X-Git-Tag: v8.13~50
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e772bddde8295fe0fdaef05b3c4c5e967116c805;p=platform%2Fupstream%2Fcoreutils.git

cp: don't mishandle existing dir dest permissions (Bug#9170)

* src/copy.c (copy_internal): If we don't create the directory,
then we cannot have omitted permissions.  Problem and trivial
fix reported by Eric Lammerts.
* tests/Makefile.am (TESTS): Add cp/existing-perm-dir.
* tests/cp/existing-perm-dir: New file.
