+====================================
+Testing head checking code: Case A-8
+====================================
+
+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 A: simple case involving a branch being superceeded by another.
+TestCase 8: single-changeset branch indirect rewrite
+
+.. old-state:
+..
+.. * 1-changeset branch
+..
+.. new-state:
+..
+.. * 1-changeset branch succeeding to A, through another unpushed changesets
+..
+.. expected-result:
+..
+.. * push allowed

+ $ cd A8
+ $ setuprepos
+ creating basic server and client repo
+ updating to branch default
+ 2 files updated, 0 files merged, 0 files removed, 0 files unresolved
+ $ cd client
+ $ hg up 0
+ 0 files updated, 0 files merged, 1 files removed, 0 files unresolved
+ $ mkcommit A1
+ created new head
+ $ hg up 0
+ 0 files updated, 0 files merged, 1 files removed, 0 files unresolved
+ $ mkcommit A2
+ created new head
+ $ hg debugobsolete `getid "desc(A0)" ` `getid "desc(A1)"`

+Actual testing
+--------------
+
+ $ hg push
+ pushing to $TESTTMP/A8/server (glob)
+ searching for changes
+ adding changesets
+ adding manifests
+ adding file changes
+ added 1 changesets with 1 changes to 1 files (+1 heads)
+ 2 new obsolescence markers
