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

  $ hg log -r 'desc("B_4")' -T '{node}' > ../main-single-branch-node_B4

(double check the heads are right before we obsolete)

Actual testing

Revealing obsolete changeset

----------------------------

Check that revealing obsolete changesets does not confuse branch computation and checks

Revealing tipmost changeset

~~~~~~~~~~~~~~~~~~~~~~~~~~~

  $ cp -R ./main-single-branch tmp-repo

  $ cd tmp-repo

  $ hg update --hidden --rev 'desc("A_4")' --quiet

  updated to hidden changeset 3d808bbc9440

  (hidden revision '3d808bbc9440' is pruned)

  $ hg log -G -T '{desc}\n'

  o  A_3

  |/

  o  A_2

  |

  o  A_1

  |

  o  root

  $ hg heads -T '{desc}\n'

  A_3

  B_1

Even when computing branches from scratch

  $ rm -rf .hg/cache/branch*

  $ rm -rf .hg/wcache/branch*

  $ hg heads -T '{desc}\n'

  A_3

  B_1

And we can get back to normal

  $ hg update null --quiet

  $ hg heads -T '{desc}\n'

  $ cd ..

  $ rm -rf tmp-repo
