branching: merge with stable

=========================================
Testing single head enforcement: Case A-1
=========================================

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 and topic
TestCase 1: A fully obsolete topic kept visible by another one.

.. old-state:
..
.. * 2 changeset changeset on topic X

..
.. new-state:
..
.. * 2 changeset changeset on topic Y at the same location
.. * 2 changeset changeset on topic X superceeding the other ones
..
.. expected-result:
..
.. * only one head detected

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

  $ mkdir B1
  $ cd B1
  $ 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
  $ mkcommit B0
  $ hg topic topic-Y
  $ mkcommit C0
  active topic 'topic-Y' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit D0
  $ hg push --new-branch
  pushing to $TESTTMP/B1/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 4 changesets with 3 changes to 4 files (+1 heads)
  1 new obsolescence markers
  obsoleted 1 changesets
  $ hg up 0
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg topic topic-X
  marked working directory as topic: topic-X
  $ mkcommit A1
  $ mkcommit B1
  $ hg debugobsolete `getid "desc(A0)" ` `getid "desc(A1)"`
  1 new obsolescence markers
  obsoleted 1 changesets
  3 new orphan changesets
  $ hg debugobsolete `getid "desc(B0)" ` `getid "desc(B1)"`
  1 new obsolescence markers
