commit c707ab26362e795d3f9dba4eb87dc7ed99a28bcb Author: Robin Lee Date: Sat Apr 8 21:21:39 2017 +0800 Fix non-standard inherented modes of directories in debuginfo In case that binary compiled from source generated in /tmp, a /usr/src/debug/tmp directory will be created with the same mode as /tmp, a.k.a 777, which should be avoided.

The fix for rhbz#444310 (commit c1a5eb - Include empty CU current dirs) was a little greedy. It would also include comp_dirs outside the build root. Those are unnecessary and we don't have a good way to store them. Such dirs (e.g. /tmp) would then show up at the root of /usr/src/debug. Fix this by including only comp_dirs under base_dir. Also only output all dirs once (during phase zero) and don't output empty dirs (which was harmless but would produce a warning from cpio). This still includes all empty dirs from the original rhbz#444310 nodir testcase and it is an alternative fix for rhbz#641022 (commit c707ab). Both fixes are necessary in case of an unexpected mode for a directory actually in the build root that we want to include in the source list.
