Subject: [PATCH v2 12/18] test-reach: test get_merge_bases_many
Date: Fri, 20 Jul 2018 16:33:20 +0000 [thread overview]
Message-ID: <20180720163227.105950-13-dstolee@microsoft.com> (raw)
In-Reply-To: <20180720163227.105950-1-dstolee@microsoft.com>
The get_merge_bases_many method returns a list of merge bases for a
single commit (A) against a list of commits (X). Some care is needed in
constructing the expected behavior because the result is not the
expected merge-base for an octopus merge with those parents but instead
the set of maximal commits that are reachable from A and at least one of
the commits in X.
Add get_merge_bases_many to 'test-tool reach' and create a test that
demonstrates that this output returns multiple results. Specifically, we
select a list of three commits such that we output two commits that are
reachable from one of the first two, respectively, and none are
reachable from the third.
