actual stripping

  $ hg strip --config extensions.strip= --rev 'desc("c_dH0")'
  saved backup bundle to $TESTTMP/client/.hg/strip-backup/fe47ea669cea-a41bf5a9-backup.hg

Test that closing heads are ignored by default
-----------------------------------------------

  $ hg up 'desc("c_aG0")'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ mkcommit c_aJ0
  created new head

pushing the new head should fails

  $ hg push -f
  pushing to $TESTTMP/single-head-server

  adding changesets
  adding manifests
  adding file changes
  transaction abort!
  rollback completed
  abort: rejecting multiple heads on branch "branch_A"
  (2 heads: 49003e504178 468bd81ccc5d)
  [255]


closing the head and pushing should succeed

  $ mkcommit c_aK0 --close-branch
  $ hg push -f
  pushing to $TESTTMP/single-head-server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 4 changesets with 4 changes to 4 files (-1 heads)


Test that closing heads can be explicitly accounted for
-------------------------------------------------------

  > [experimental]
  > single-head-per-branch:account-closed-heads = yes
  > EOF

  $ hg up 'desc("c_aG0")'

Test that config can be overriden as the boolean it is
------------------------------------------------------

  $ cat <<EOF >> $TESTTMP/single-head-server/.hg/hgrc
  > [experimental]
  > single-head-per-branch = no
  > EOF

Because of previous test, we'll also push c_aL0 and c_aM0.

  $ hg out -T "{desc}\n"

  searching for changes
  c_aL0
  c_aM0

Let's make a new head and push everything. The server feedback will mention
exactly one new head because c_aM0 is closed.

  $ hg up 'desc("c_aG0")'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ mkcommit c_aN0
  created new head

  adding file changes
  added 3 changesets with 3 changes to 3 files (+1 heads)
  $ cd ..


Test that singe-head-per-branch can be restricted to public changes
