"git pack-objects" learns to find delta bases from blobs at the same path, using the --path-walk API. * ds/path-walk-2: pack-objects: allow --shallow and --path-walk path-walk: add new 'edge_aggressive' option pack-objects: thread the path-based compression pack-objects: refactor path-walk delta phase scalar: enable path-walk during push via config pack-objects: enable --path-walk via config repack: add --path-walk option t5538: add tests to confirm deltas in shallow pushes pack-objects: introduce GIT_TEST_PACK_PATH_WALK p5313: add performance tests for --path-walk pack-objects: update usage to match docs pack-objects: add --path-walk option pack-objects: extract should_attempt_deltas()
