Testing head checking code: Case A-5

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

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 5: New changeset as parent of the successor

.. old-state:

.. * 1-changeset branch

.. new-state:

.. * 2rchangeset branch, head is a successor, but other is new

Test setup

----------

  $ mkdir A5

  $ cd A5

  $ 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 B0

  created new head

  $ mkcommit A1

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

  $ hg log -G --hidden

Actual testing

--------------

  $ hg push

  pushing to $TESTTMP/A5/server (glob)

  searching for changes

  adding changesets

  adding manifests

  adding file changes

  added 2 changesets with 2 changes to 2 files (+1 heads)

  1 new obsolescence markers
