Code clean-up. * jk/loose-object-cache-oid: prefer "hash mismatch" to "sha1 mismatch" sha1-file: avoid "sha1 file" for generic use in messages sha1-file: prefer "loose object file" to "sha1 file" in messages sha1-file: drop has_sha1_file() convert has_sha1_file() callers to has_object_file() sha1-file: convert pass-through functions to object_id sha1-file: modernize loose header/stream functions sha1-file: modernize loose object file functions http: use struct object_id instead of bare sha1 update comment references to sha1_object_info() sha1-file: fix outdated sha1 comment references
