Subject: [RFC 06/14] fetch: refactor to make function args narrower
Date: Wed, 25 Jan 2017 14:02:59 -0800 [thread overview]
Message-ID: <4fc5ef88ae2135db475c557498e7a805afb693b9.1485381677.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1485381677.git.jonathantanmy@google.com>
In-Reply-To: <cover.1485381677.git.jonathantanmy@google.com>
Refactor find_non_local_tags and get_ref_map to only take the
information they need instead of the entire transport struct. Besides
improving code clarity, this also improves their flexibility, which will
be needed in a future patch.
