Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
rust: don't star export from the `revlog` module This made a lot of the imports confusing because they didn't make sense at the top level (so, outside of `revlog`), and they hide the more common types when autocompleting.

================================================================
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.

Setup graph

graph with a single branch
--------------------------

We want some branching and some obsolescence

  $ hg init main-single-branch
  $ cd main-single-branch
  $ mkcommit root
  $ mkcommit A_1
  $ 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
