Testing head checking code: Case A-4

====================================

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Category A: simple case involving a branch being superseded by another.

TestCase 4: New changeset as children of the successor

.. old-state:

..

.. * 1-changeset branch

..

.. new-state:

..

.. * 2-changeset branch, first is a successor, but head is new

..

.. expected-result:

.. * push allowed

Test setup

----------

  $ mkdir A4

  $ cd A4

  $ 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 debugobsolete `getid "desc(A0)" ` `getid "desc(A1)"`

  1 new obsolescence markers

  obsoleted 1 changesets

  $ mkcommit B0

  $ hg log -G --hidden
