===============================================
Testing content-divergence resolution: Case B.1
===============================================

Independent rewrites of same changeset can lead to content-divergence. In most
common cases, it can occur when multiple users rewrite the same changeset
independently and push it.

This test belongs to a series of tests checking the resolution of content-divergent
changesets.

Category B: parents are obsolete
Testcase 1: one side amended changes and other rebased to in-between successor of basep1
Variants:
# a: default resolution
# b: minimal resolution using `experimental.evolution.divergence-resolution-minimal=True`

B.1 Relocated backward; Rebased to parent's successor
=====================================================

.. (Divergence reason):
..    local: rebased to the 'in-between' successor of basep1
..    other: amended some changes
.. The default resolution here is that we choose the final successor as resolution parent,
.. but this behavior can be changed to use the 'in-between' successor as resolution parent
.. by using a config option `experimental.evolution.divergence-resolution-minimal=True`
..
.. This test case is considered complicated and can change its behavior acc. to the user
.. feedback. For more, please look at section 'D-A3.1' in troubles-handling.rst
