snapshot: consider all snapshots in the parents' chains There are no reasons to only consider full snapshot as a possible base for an intermediate snapshot. Now that the basic principles have been set, we can start adding more levels of snapshots. We now consider all snapshots in the parent's chains (full or intermediate). This creates a chain of intermediate snapshots, each smaller than the previous one. # Effect On The Test Repository In the test repository, we can see a decrease in the revlog size and slightly shorter delta chain. However, that approach creates snapshots more frequently, increasing the risk of ending into problematic cases in very branchy repositories (not triggered by the test repository). The next changesets will remove that risk by adding logic that increases deltas reuse.

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

  $ hg push --rev 'desc(C0)'
  pushing to $TESTTMP/C4/server

  abort: push creates new remote head 0f88766e02d6!
  (merge or see 'hg help push' for details about pushing new heads)
