23 # Restoring of directory modes and timestamps works correctly only
24 # if the archive has normal member ordering, i.e. each directory
25 # member is immediately followed by members located under that directory.
26 # This is not true for incremental archives, where directory members
27 # precede the non-directory ones. Due to this, GNU tar up to version 1.15.2
28 # failed to correctly restore directory timestamps from an incremental
29 # archive if this directory contained some files in it.

55 # When restoring from this directory structure, 'dir/subdir2/' used to
56 # trigger apply_nonancestor_delayed_set_stat() which restored stats for
57 # 'subdir1' prior to restoring 'dir/subdir1/foofile'. Then, restoring the
58 # latter clobbered the directory timestamp.
