Subject: [PATCH 1/2] parse_object(): drop extra "has" check before checking object type
Date: Thu, 17 Nov 2022 17:37:58 -0500	[thread overview]
Message-ID: <Y3a3xnYNyiDQknTM@coredump.intra.peff.net> (raw)
In-Reply-To: <Y3a3qcqNG8W3ueeb@coredump.intra.peff.net>

When parsing an object of unknown type, we check to see if it's a blob,
so we can use our streaming code path. This uses oid_object_info() to
check the type, but before doing so we call repo_has_object_file(). This
latter is pointless, as oid_object_info() will already fail if the
object is missing. Checking it ahead of time just complicates the code
and is a waste of resources (albeit small).

Let's drop the redundant check.
