+====================================
+Testing head checking code: Case D-3
+====================================
+
+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 3: multi-changeset branch, split on multiple new others, only one of them is pushed
+
+.. old-state:
+..
+.. * 2 changesets branch
+..
+.. new-state:
+..
+.. * 2 new branches, each superseding one changeset in the old one.
+..
+.. expected-result:
+..
+.. * pushing only one of the resulting branch (either of them)
+.. * push denied

+Test setup
+----------
+
+ $ mkdir D3
+ $ cd D3
+ $ setuprepos
+ creating basic server and client repo
+ updating to branch default
+ 2 files updated, 0 files merged, 0 files removed, 0 files unresolved
+ $ cd server
+ $ mkcommit B0
+ $ hg up 0
+ 0 files updated, 0 files merged, 2 files removed, 0 files unresolved
+ $ cd ../client
+ $ hg pull
+ pulling from $TESTTMP/D3/server (glob)
+ searching for changes
+ adding changesets
+ adding manifests
+ adding file changes
+ added 1 changesets with 1 changes to 1 files
+ (run 'hg update' to get a working copy)
+ $ 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 B1
+ created new head
+ $ hg debugobsolete `getid "desc(A0)" ` `getid "desc(A1)"`
+ $ hg debugobsolete `getid "desc(B0)" ` `getid "desc(B1)"`
+ $ hg log -G --hidden

+
+Actual testing
+--------------
+
+ $ hg push --rev 'desc(A1)'
+ pushing to $TESTTMP/D3/server (glob)
+ searching for changes
+ abort: push creates new remote head f6082bc4ffef!
+ (merge or see 'hg help push' for details about pushing new heads)
+ [255]
+ $ hg push --rev 'desc(B1)'
+ pushing to $TESTTMP/D3/server (glob)
+ searching for changes
+ abort: push creates new remote head 25c56d33e4c4!
+ (merge or see 'hg help push' for details about pushing new heads)
+ [255]
+
+Extra testing
+-------------
+
+In this case, even a bare push is creating more heads
+
+ $ hg push
+ pushing to $TESTTMP/D3/server (glob)
+ searching for changes
+ abort: push creates new remote head 25c56d33e4c4!
+ (merge or see 'hg help push' for details about pushing new heads)
