evolve: return the new replacement node to be stored in evolvestate
While resolving phase-divergence, we can end up obsoleting the phase-divergent
commit in favor of the public commit. Before this patch we return the node of
public commit to store as a replacement of the phase-divergent commit.
The above will not cause any problem till the time we use `hg evolve --abort` on
an interrupted evolve which tries to strip the replacement nodes because it
thinks that the replacements nodes are the ones which are created during the
resolution and are new.
Since we will be stripping a public node, `evolve --abort` will error out saying
cannot strip public changeset, unable to abort evolve which is bad.
We should make sure, replacements should only consist of new nodes formed. If
the instablity is resolved by obsoleting in favour of old changeset, we should
not store the old changeset in replacements in evolvestate.
============================================
Testing obsolescence markers push: Cases D.2
============================================
Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).
This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.
Category D: Partial Information Case
TestCase 2: missing prune target (prune in "pushed set")
D.2 missing prune target (prune in "pushed set")
