=========================================
Testing single head enforcement: Case B-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.

Category B: Involving obsolescence with topic
TestCase 3: Full superseding of a branch interleaved with another

Test setup
----------

  $ mkdir B3
  $ cd B3
  $ setuprepos single-head
  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 topic -r . topic-X
  switching to topic topic-X
  changed topic on 1 changesets to "topic-X"
  $ hg strip --config extensions.strip= --hidden 'hidden()' --no-backup # clean old A0
  $ hg topic topic-Y
  $ mkcommit B0
  active topic 'topic-Y' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg topic topic-X
  $ mkcommit C0
  $ hg topic topic-Y
  $ mkcommit D0
  $ hg push --new-branch
  pushing to $TESTTMP/B3/server
  searching for changes

  obsoleted 1 changesets
  $ hg up 0
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg topic topic-X
