Testing head checking code: Case D-1

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

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 D: remote head is "obs-affected" locally, but result is not part of the push

TestCase 1: remote head is rewritten, but successors is not part of the push

.. old-state:

.. * 1 changeset branch

.. new-state:

.. * 1 changeset branch succeeding the old branch

.. * 1 new unrelated branch

Test setup

----------

  $ mkdir D1

  $ cd D1

  $ 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

  $ hg up 0

  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ mkcommit B0

  created new head

  $ hg log -G --hidden

Actual testing

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

  $ hg push -r 'desc(B0)'

  pushing to $TESTTMP/D1/server (glob)

  searching for changes

  abort: push creates new remote head 74ff5441d343!

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