=============================
Test distributed obsolescence
=============================

This file test various cases where data (changeset, phase, obsmarkers) is
added to the repository in a specific order. Usually, this order is unlikely
to happen in the local case but can easily happen in the distributed case.

  $ unset HGUSER
  $ unset EMAIL
  $ . $TESTDIR/testlib/obsmarker-common.sh
  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > rebase =
  > [experimental]
  > evolution = all
  > [phases]
  > publish = False
  > [ui]
  > logtemplate= {rev}:{node|short} {desc}{if(obsfate, " [{join(obsfate, "; ")}]")}\n
  > EOF

Check distributed chain building
================================

Test case where a changeset is marked as a successor of another local
changeset while the successor has already been obsoleted remotely.

The chain of evolution should seamlessly connect and all but the new version
(created remotely) should be seen as obsolete.

Check getting changesets after getting the markers
=================================================

This test case covers the scenario where commits are received -after- we
received some obsolescence markers turning them obsolete.

For example, we pull some successors from a repository (with associated
predecessors marker chain) and then later we pull some intermediate
precedessors changeset from another repository. Obsolescence markers must
apply to the intermediate changeset. They have to be obsolete (and hidden).

Avoiding pulling the changeset in the first place is a tricky decision because
there could be non-obsolete ancestors that need to be pulled, but the
discovery cannot currently find these (this is not the case in this tests). In
addition, we could also have to pull the changeset because they have children.
In this case, they would not be hidden (yet) because of the orphan descendant,
but they would still have to be obsolete. (This is not tested in this case
either).
