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

Check hgweb's load order:

  > from mercurial.hgweb import wsgicgi

  > application = hgweb('.', 'test repo')
  > wsgicgi.launch(application)
  > EOF

  $ SCRIPT_NAME='/' SERVER_PORT='80' SERVER_NAME='localhost' python hgweb.cgi \
  >    | grep '^[0-9]) ' # ignores HTML output
  1) foo imported
  1) bar imported
  2) foo uisetup
  2) bar uisetup
  3) foo extsetup
  3) bar extsetup
  4) foo reposetup
  4) bar reposetup
  4) foo reposetup
  4) bar reposetup
