[PATCH 1/8] fetch.c: Remove useless lookup_object_type() call in process()

From: Sergey Vlasov <vsu@altlinux.ru>
Date: Sep 21, 2005, 16:18 UTC
Message-ID: <20050921161855.896F1E010FC@center4.mivlgu.local>
In-Reply-To: <20050921161829.GA20944@master.mivlgu.local>

In all places where process() is called except the one in pull() (which is executed only once) the pointer to the object is already available, so pass it as the argument to process() instead of sha1 and avoid an unneeded call to lookup_object_type().
