Subject: [PATCH 5/6] submodule: improve submodule_has_commits
Date: Fri, 28 Apr 2017 16:54:01 -0700 [thread overview]
Message-ID: <20170428235402.162251-6-bmwill@google.com> (raw)
In-Reply-To: <20170428235402.162251-1-bmwill@google.com>
Teach 'submodule_has_commits()' to ensure that if a commit exists in a
submodule, that it is also reachable from a ref.
This is a prepritory step prior to merging the logic which checkes for
changed submodules when fetching or pushing.
