Test symlink traversing when accessing history:

(build a changeset where the path exists as a directory)

  $ hg up 0

  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ mkdir b

  $ echo c > b/a

  $ hg add b/a

  $ hg ci -m 'add directory b'

  created new head

Test that hg cat does not do anything wrong the working copy has 'b' as directory

  $ hg cat b/a

  $ hg cat -r "desc(directory)" b/a

try linear update including symlinked directory and its content: paths are

audited first by calculateupdates(), where no symlink is created so both

path 'a' is audited as a directory first, which should be audited again as

a symlink.
