4Subject: [PATCH 1/2] non-recursive extract and list
5
6Sometimes it makes sense to extract or list a directory contained in
7an archive without also doing the same for the content of the
8directory, i.e. allowing -n (= --no-recursion) in combination with the
9x and t modes.
10
11bsdtar uses the match functionality in libarchive to track include
12matches. A new libarchive API call
13archive_match_include_directories_recursively() gets introduced to
14influence the matching behavior, with the default behavior as before.
15
16Non-recursive matching can be achieved by anchoring the path match at
17both start and end. Asking for a directory which itself isn't in the
18archive when in non-recursive mode is an error and handled by the
19existing mechanism for tracking unused inclusion entries.
