−====================================
+
−Testing head checking code: Case D-5
+
−====================================
+
−
+
−Mercurial checks for the introduction of new heads on push. Evolution comes
+
−into play to detect if existing branches on the server are being replaced by
+
−some of the new one we push.
+
−
+
−This case is part of a series of tests checking this behavior.
+
−
+
−Category D: remote head is "obs-affected" locally, but result is not part of the push
+
−TestCase 5: multi-changeset branch, split on multiple other, (head on its own new branch)
+
−
+
−.. old-state:
+
−..
+
−.. * 2 branch (1 changeset, and 2 changesets)
+
−..
+
−.. new-state:
+
−..
+
−.. * 1 new branch superceeding the head of the old-2-changesets-branch,
+
−.. * 1 new changesets on the old-1-changeset-branch superceeding the base of the other
+
−..
+
−.. expected-result:
+
−..
+
−.. * push the new branch only -> push denied
+
−.. * push the existing branch only -> push allowed
+
−..   /!\ This push create unstability/orphaning on the other hand and we should
+
−..  probably detect/warn agains that.
