### todo: it's inefficient to keep calling externals_test_setup() for
### every test.  It's slow.  But it's very safe -- we're guaranteed to
### have a clean repository, built from the latest Subversion, with
### the svn:externals properties preset in a known way.  Right now I
### can't think of any other way to achieve that guarantee, so the
### result is that each individual test is slow.

def externals_test_setup(sbox):
  """Set up a repository in which some directories have the externals property,
  and set up another repository, referred to by some of those externals.
  Both repositories contain greek trees with five revisions worth of
  random changes, then in the sixth revision the first repository --
  and only the first -- has some externals properties set.  ### Later,
  test putting externals on the second repository. ###

  The arrangement of the externals in the first repository is:

    /A/B/ ==>  ^/A/D/gamma                      gamma
    /A/C/ ==>  exdir_G                          <scheme>:///<other_repos>/A/D/G
               ../../../<other_repos_basename>/A/D/H@1 exdir_H

    /A/D/ ==>  ^/../<other_repos_basename>/A    exdir_A
               //<other_repos>/A/D/G/           exdir_A/G/
               exdir_A/H -r 1                   <scheme>:///<other_repos>/A/D/H
               /<some_paths>/A/B                x/y/z/blah

  A dictionary is returned keyed by the directory created by the
  external whose value is the URL of the external.

### modules, you can get the first "Updated to revision X" line, and
### then there will be more "Updated to..." and "Checked out..." lines
### following it, one line for each new or changed external.
