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

Testing head checking code: Case E-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 E: case involving changeset on multiple branch

TestCase 8: moving interleaved branch away from each other

.. old-state:

..

.. * 2-changeset on branch default

.. * 1-changeset on branch Z (between the two other)

..

.. new-state:

..

.. * 2-changeset on branch default, aligned

.. * 1-changeset on branch Z (at the same location)

..

.. expected-result:

.. * push allowed

Test setup

----------

  $ mkdir E1

  $ cd E1

  $ 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 branch Z

  marked working directory as branch Z

  (branches are permanent and global, did you want a bookmark?)

  $ mkcommit B0

  $ hg branch default --force

  marked working directory as branch default

  $ mkcommit C0

  created new head

  (consider using topic for lightweight branches. See 'hg help topic')

  $ hg push --new-branch

  pushing to $TESTTMP/E1/server

  searching for changes

  adding changesets

  adding manifests

  adding file changes

  added 2 changesets with 2 changes to 2 files

  $ hg up 0

  0 files updated, 0 files merged, 3 files removed, 0 files unresolved

  $ mkcommit A1

  created new head

  (consider using topic for lightweight branches. See 'hg help topic')

  $ mkcommit C1

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

  1 new obsolescence markers

  obsoleted 1 changesets

  2 new orphan changesets

  $ hg debugobsolete `getid "desc(C0)" ` `getid "desc(C1)"`

  1 new obsolescence markers

  obsoleted 1 changesets

  $ hg log -G --hidden

Actual testing

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

  $ hg push -r 'desc("C1")'

  pushing to $TESTTMP/E1/server

  searching for changes

  adding changesets

  adding manifests

  adding file changes

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

  2 new obsolescence markers

  obsoleted 2 changesets

  1 new orphan changesets
