Convert read_sha1_file to take a pointer to struct object_id and rename it read_object_file. Do the same for read_sha1_file_extended. Convert one use in grep.c to use the new function without any other code change, since the pointer being passed is a void pointer that is already initialized with a pointer to struct object_id. Update the declaration and definitions of the modified functions, and apply the following semantic patch to convert the remaining callers: @@ expression E1, E2, E3; @@ - read_sha1_file(E1.hash, E2, E3) + read_object_file(&E1, E2, E3) @@ expression E1, E2, E3; @@ - read_sha1_file(E1->hash, E2, E3) + read_object_file(E1, E2, E3) @@ expression E1, E2, E3, E4; @@ - read_sha1_file_extended(E1.hash, E2, E3, E4) + read_object_file_extended(&E1, E2, E3, E4) @@ expression E1, E2, E3, E4; @@ - read_sha1_file_extended(E1->hash, E2, E3, E4) + read_object_file_extended(E1, E2, E3, E4) Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
