evolve: consider all obsolete ancestors when finding new parent for orphan
Both the old and the new logic have in common that the orphan changeset is
moved to the tipmost successor of one or more ancestors of the orphan
changeset. The previous logic considered only the first non-pruned ancestor of
the orphan changeset. The new logic considers all obsolete ancestors of the
orphan changeset.
The logic in _possibledestination() had to be changed to be consistent with the
new logic.
====================================
Testing head checking code: Case C-1
====================================
Mercurial checks for the introduction of multiple heads on push. Evolution
comes into play to detect if existing heads on the server are being replaced by
some of the new heads we push.
This test file is part of a series of tests checking this behavior.
Category C: checking case were the branch is only partially obsoleted.
TestCase 1: 2 changeset branch, only the head is rewritten
.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * 1 new changesets branches superceeding only the head of the old one
.. * base of the old branch is still alive
..
.. expected-result:
..
.. * push denied
