stack: make a deep copy of `dependencies` before modifying its items
The algorithm later on in this method uses .remove() to remove individual
elements from items in dependencies, which before this patch modified the
cached property contents. So for further use that dictionary was in the form of
{1: set([])}, i.e. all sets were empty.
This deep copy block could be way simpler, but the problem is that sometimes we
get lists of _succs() from evolvebits.builddependencies(). Note: this happens
only in topic's stack version of builddependencies() and it looks like a
suboptimal way to handle multiple successors (see evolve's counterpart
function).
stack.builddependencies method is removed, it has served its purpose (see the
previous patch).
====================================
Testing head checking code: Case C-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 C: case were the branch is only partially obsoleted
TestCase 4: 2 changeset branch, only the base is pruned
.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old base is pruned
.. * 1 new unrelated branch
..
.. expected-result:
..
.. * push denied
