obscache: skip the cache entirely if not up to date
The current update code has some race condition windows around updating. But we
also ensure the cache are up to date with every transaction. So outdated cache
mean another client have been mudding the repository but things will get back
in place at the next transaction.
So we just skip using the cache when not up to date. This is not the best we
could do. But this is good enough for now.
====================================
Testing head checking code: Case D-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 D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 1: remote branch has 2 changes, head is pruned, other is rewritten but result is not pushed
.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old head is pruned
.. * 1 new branch succeeding to the other changeset in the old branch
.. * 1 new unrelated branch
..
.. expected-result:
..
.. * push allowed
.. * pushing only the unrelated branch: denied
