A new libarchive API call +archive_match_include_directories_recursively() gets introduced to +influence the matching behavior, with the default behavior as before. + +Non-recursive matching can be achieved by anchoring the path match at +both start and end. Asking for a directory which itself isn't in the +archive when in non-recursive mode is an error and handled by the +existing mechanism for tracking unused inclusion entries. + +Upstream-Status: Submitted [https://github.com/libarchive/libarchive/pull/812] + +Signed-off-by: Patrick Ohly <patrick.ohly@intel.com> + +--- + libarchive/archive.h | 2 ++ + libarchive/archive_match.c | 30 +++++++++++++++++++++++++++++- + tar/bsdtar.1 | 3 +-- + tar/bsdtar.c | 12 ++++++++++-- + 4 files changed, 42 insertions(+), 5 deletions(-) + +diff --git a/libarchive/archive.h b/libarchive/archive.h +index ff401e9..38d8746 100644 +--- a/libarchive/archive.h ++++ b/libarchive/archive.h +@@ -1085,6 +1085,8 @@ __LA_DECL int archive_match_excluded(struct archive *, + */ + __LA_DECL int archive_match_path_excluded(struct archive *, + struct archive_entry *); ++/* Control recursive inclusion of directory content when directory is included.
