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 'open("data1", "wb").write(b"".join(b"%d\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'):

#if reporevlogstore

  $ 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

#endif

Trigger branchcache creation:

  $ hg branches

  $ ls .hg/cache

Default operation:

  $ hg clone . ../b
