changeset 34651:e88dbbcf2a56

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
test: add an extra case for obsolescence distributed case This changeset introduces a new documented test case for a distributed obsolescence scenario. The scenario involves a simple case where some obsolescence markers are retrieved before the changeset they affect. See the test case documentation for details. We also test variants where the changesets are added from a bundle.

+
+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).
