Code review comment for lp:~dpigott/lava-scheduler-tool/fix821400-add-token-file

We can probably remove that line

81 +# server = AuthenticatingServerProxy(
82 +# self.args.SERVER, auth_backend=KeyringAuthBackend())

While this looks okay I think parsing the URL would be saner for bogus URLs.
22 +def normalize_xmlrpc_url(uri):
23 + if '://' not in uri:
24 + uri = 'http://' + uri
25 + if not uri.endswith('/'):
26 + uri += '/'
27 + if not uri.endswith('/RPC2/'):
28 + uri += 'RPC2/'
29 + return uri

Instead of checking this manually you can use MutuallyExclusiveGroup from argparse. It makes --help document this and allows you to express the same limitation without client-side code. See: http://argparse.googlecode.com/svn/trunk/doc/other-methods.html#mutual-exclusion

56 + if parsed_host.password:
57 + raise LavaCommandError(
58 + "Token specified in url but --token-file also passed.");
