Subject: [PATCH v4 3/8] sha1_file: rename LOOKUP_REPLACE_OBJECT
Date: Mon, 19 Jun 2017 18:03:10 -0700 [thread overview]
Message-ID: <6f6e8237db12ec2cd8fb4c8e2951bfc867a656a2.1497920092.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1497920092.git.jonathantanmy@google.com>
In-Reply-To: <cover.1497920092.git.jonathantanmy@google.com>
The LOOKUP_REPLACE_OBJECT flag controls whether the
lookup_replace_object() function is invoked by
sha1_object_info_extended(), read_sha1_file_extended(), and
lookup_replace_object_extended(), but it is not immediately clear which
functions accept that flag.
Therefore restrict this flag to only sha1_object_info_extended(),
renaming it appropriately to OBJECT_INFO_LOOKUP_REPLACE and adding some
documentation. Update read_sha1_file_extended() to have a boolean
parameter instead, and delete lookup_replace_object_extended().
parse_sha1_header() also passes this flag to
parse_sha1_header_extended() since commit 46f0344 ("sha1_file: support
reading from a loose object of unknown type", 2015-05-03), but that has
had no effect since that commit. Therefore this patch also removes this
flag from that invocation.
