−Testing single head enforcement: Case A-3
+
−=========================================
+
−
+
−A repository is set to only accept a single head per name (typically named
+
−branch). However, obsolete changesets can make this enforcement more
+
−complicated, because they can be kept visible by other changeset on other
+
−branch.
+
−
+
−This case is part of a series of tests checking this behavior.
+

+
