From 6aea6baeb3ece6c832dbdf1deed09f41aebf85c2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Sat, 5 Feb 2022 00:48:34 +0100 Subject: object-file API: pass an enum to read_object_with_reference() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change the read_object_with_reference() function to take an "enum object_type". It was not prepared to handle an arbitrary "const char *type", as it was itself calling type_from_string(). Let's change the only caller that passes in user data to use type_from_string(), and convert the rest to use e.g. "OBJ_TREE" instead of "tree_type". The "cat-file" caller is not on the codepath that handles"--allow-unknown", so the type_from_string() there is safe. Its use of type_from_string() doesn't functionally differ from that of the pre-image.
