Prepare repo a:

  $ hg init a
  $ cd a
  $ echo a > a
  $ hg add a
  $ hg commit -m test
  $ echo first line > b
  $ hg add b

Create a non-inlined filelog:

  $ $PYTHON -c 'file("data1", "wb").write("".join("%s\n" % x for x in range(10000)))'
  $ for j in 0 1 2 3 4 5 6 7 8 9; do
  >   cat data1 >> b
  >   hg commit -m test
  > done

List files in store/data (should show a 'b.d'):

  $ for i in .hg/store/data/*; do
  >   echo $i
  > done
  .hg/store/data/a.i
  .hg/store/data/b.d
  .hg/store/data/b.i

Trigger branchcache creation:

  $ hg branches
  default                       10:a7949464abda
  $ ls .hg/cache
  branch2-served
  rbc-names-v1
  rbc-revs-v1

Default operation:

  $ hg clone . ../b
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd ../b

Ensure branchcache got copied over:

  $ ls .hg/cache
  branch2-served

  $ cat a

  $ hg verify

  $ cd a
  $ hg cat a

Check that we drop the 'file:' from the path before writing the .hgrc:

  $ hg clone file:a e
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ grep 'file:' e/.hg/hgrc

Check that path aliases are expanded:

  $ hg clone -q -U --config 'paths.foobar=a#0' foobar f
  $ hg -R f showconfig paths.default
  $TESTTMP/a#0 (glob)

Use --pull:

  $ hg clone --pull a g
