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 * The old branch is still alive (base is obsolete, head is alive)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

  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

  new changesets d73caddc5533 (1 drafts)

  (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)"`

  obsoleted 1 changesets

  1 new orphan changesets

  $ hg log -G --hidden

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

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

  pushing to $TESTTMP/C2/server (glob)
