Testing head checking code: Case C-2

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

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 C: case were the branch is only partially obsoleted

TestCase 2: 2 changeset branch, only the base is rewritten

.. old-state:

..

.. * 2 changeset branch

..

.. new-state:

..

.. * 1 new changesets branches superceeding only the base of the old one

.. * The old branch is still alive (base is obsolete, head is alive)

..

.. expected-result:

..

.. * push denied

Test setup

----------

  $ mkdir C2

  $ cd C2

  $ 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

  $ cd ../client

  $ hg pull

  pulling from $TESTTMP/C2/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 debugobsolete `getid "desc(A0)" ` `getid "desc(A1)"`

  $ hg log -G --hidden

Actual testing

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

  $ hg push --rev 'desc(A1)'

  pushing to $TESTTMP/C2/server (glob)

  searching for changes

  abort: push creates new remote head f6082bc4ffef!

  (merge or see 'hg help push' for details about pushing new heads)
