Merge branch 'jc/streaming' into next
* jc/streaming: sha1_file: use the correct type (ssize_t, not size_t) for read-style function streaming: read loose objects incrementally sha1_file.c: expose helpers to read loose objects streaming: read non-delta incrementally from a pack streaming_write_entry(): support files with holes convert: CRLF_INPUT is a no-op in the output codepath streaming_write_entry(): use streaming API in write_entry() streaming: a new API to read from the object store write_entry(): separate two helper functions out unpack_object_header(): make it public sha1_object_info_extended(): hint about objects in delta-base cache sha1_object_info_extended(): expose a bit more info packed_object_info_detail(): do not return a string
