Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
typing: make the manifest classes known to pytype These are the same changes as c1d7ac70980b and 45270e286bdc made to dirstate, for the same reasons. The migration away from decorating the classes with `@interfaceutil.implementer` was started back in 3e9a660b074a, but missed one.

================================================================
test the interaction of the branch cache with obsolete changeset
================================================================

Some corner case have been covered by unrelated test (like rebase ones) this
file meant to gather explicite testing of those.

graph with a single branch

We want some branching and some obsolescence

  $ mkcommit A_2
  $ hg update 'desc("A_2")' --quiet
  $ mkcommit B_1
  $ mkcommit B_2
  $ mkcommit B_3
  $ mkcommit B_4
  $ hg update 'desc("A_2")' --quiet
  $ mkcommit A_3
  created new head
  $ mkcommit A_4
  $ hg up null --quiet
  $ hg clone --noupdate . ../main-single-branch-pre-ops
  $ hg log -r 'desc("A_1")' -T '{node}' > ../main-single-branch-node_A1
  $ hg log -r 'desc("A_2")' -T '{node}' > ../main-single-branch-node_A2
