Check that the behavior of rebase with obsolescence markers is maintained
despite inhibit

  $ hg up a438c045eb37
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg rebase -r 15:: -d 21 --config experimental.rebaseskipobsolete=True
  note: not rebasing 15:2d66e189f5b5 "add cM", already in destination as 21:721c3c279519 "add cM"
  rebasing 16:a438c045eb37 "add cN"

Directaccess should load after some extensions precised in the conf
With no extension specified:

  $ cat >> $HGRCPATH << EOF

  $ hg id

  > EOF
  $ hg id
  ['rebase', 'strip', 'evolve', 'inhibit', 'testextension', 'directaccess']

Inhibit should not work without directaccess
  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > directaccess=!
  > testextension=!
  > EOF
  $ hg up .
  cannot use inhibit without the direct access extension
  (please enable it or inhibit won't work)

hg push should not allow directaccess unless forced with --hidden
We copy the inhibhit repo to inhibit2 and make some changes to push to inhibit

  $ cp -r inhibit inhibit2
  $ pwd=$(pwd)
  $ cd inhibit
  $ mkcommit pk
  created new head
  $ hg id
  003a4735afde tip
  $ echo "OO" > pk
  $ hg amend
  $ hg id

Hidden commits cannot be pushed without --hidden
  $ hg push -r 003a4735afde $pwd/inhibit2
  pushing to $TESTTMP/inhibit2
  abort: hidden revision '003a4735afde'!
  (use --hidden to access hidden revisions)

Visible commits can still be pushed

Pulling from a inhibit repo to a non-inhibit repo should work
