Marco Miller 734d5bb3c9 RefDirectory: remove ref lock file for following ref dir removal Before this fix, ref directory removal did not work. That was because the ref lock file was still in the leaf directory at deletion time. Hence no deep ref directories were ever deleted, which negatively impacted performance under large directory structure circumstances. This fix removes the ref lock file before attempting to delete the ref directory (which includes it). The other deep parent directories are therefore now successfully deleted in turn, since leaf's content (lock file) gets removed first. So, given a structure such as refs/any/directory[/**], this fix now deletes all empty directories up to -and including- 'directory'. The 'any' directory (e.g.) does not get deleted even if empty, as before. The ref lock file is still also removed in the calling block's finally clause, just in case, as before. Such double-unlock brought by this fix is harmless (a no-op). A new (private) RefDirectory#delete method is introduced to support this #pack-specific case; other RefDirectory#delete callers remain untouched.
