Testing head checking code: Case B-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 B: simple case involving pruned changesets

TestCase 4: multi-changeset branch, all are pruned

.. old-state:

..

.. * 2 changeset branch

..

.. new-state:

..

.. * old branch is pruned

..

.. expected-result:

..

.. * push allowed

Test setup

----------

  $ mkdir B4

  $ cd B4

  $ 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/B4/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 C0

  created new head

  $ hg debugobsolete --record-parents `getid "desc(A0)"`

  $ hg debugobsolete --record-parents `getid "desc(B0)"`

  $ hg log -G --hidden

Actual testing

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

  $ hg push

  pushing to $TESTTMP/B4/server (glob)

  searching for changes

  adding changesets

  adding manifests

  adding file changes

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

  2 new obsolescence markers

  obsoleted 2 changesets

  $ cd ../..
