Setup the server

  $ hginit master
  $ cd master
  $ cat >> .hg/hgrc <<EOF
  > [extensions]
  > treemanifest=
  > [treemanifest]
  > server=True
  > treeonly=True
  > [remotefilelog]
  > server=True
  > shallowtrees=True
  > EOF

Setup the client

  $ cd ..
  $ hgcloneshallow ssh://user@dummy/master client -q --config treemanifest.treeonly=True
  $ cd client
  $ cat >> .hg/hgrc <<EOF
  > [extensions]
  > treemanifest=
  > 
  > [treemanifest]
  > sendtrees=True
  > treeonly=True
  > 
  > [remotefilelog]
  > reponame=treeonlyrepo
  > EOF

Make some commits

  $ cd ../master
  $ mkdir subdir
  $ echo a >> subdir/foo
  $ hg commit -Aqm 'a > subdir/foo'
  $ echo b >> subdir/foo
  $ hg commit -Aqm 'b >> subdir/foo'
  $ echo c >> subdir/foo
  $ hg commit -Aqm 'c >> subdir/foo'
  $ echo d >> subdir/foo
  $ hg commit -Aqm 'd >> subdir/foo'

Test that log -p downloads each tree using the prior tree as a base

  $ cd ../client
  $ hg pull -q
  $ hg up tip
