Check that extensions are loaded in phases:

  $ cat > foo.py <<EOF

  > import os

  > name = os.path.basename(__file__).rsplit('.', 1)[0]

  > print "1) %s imported" % name

  > def uisetup(ui):

  >     print "2) %s uisetup" % name

  > def extsetup():

  >     print "3) %s extsetup" % name

  > def reposetup(ui, repo):

  >    print "4) %s reposetup" % name

  > EOF

  $ cp foo.py bar.py

  $ echo 'foo = foo.py' >> $HGRCPATH

  $ echo 'bar = bar.py' >> $HGRCPATH

Command with no output, we just want to see the extensions loaded:

  $ hg paths

  1) foo imported

  1) bar imported

  2) foo uisetup

  2) bar uisetup

  3) foo extsetup

  3) bar extsetup

  4) foo reposetup

  4) bar reposetup
