Nova Client Style Commandments ============================== - Step 1: Read the OpenStack Style Commandments http://docs.openstack.org/developer/hacking - Step 2: Read on Nova Client Specific Commandments --------------------------------- None so far Text encoding ------------- - All text within python code should be of type 'unicode'. WRONG: >>> s = 'foo' >>> s 'foo' >>> type(s) RIGHT: >>> u = u'foo' >>> u u'foo' >>> type(u) - Transitions between internal unicode and external strings should always be immediately and explicitly encoded or decoded. - All external text that is not explicitly encoded (database storage, commandline arguments, etc.) should be presumed to be encoded as utf-8. WRONG: mystring = infile.readline() myreturnstring = do_some_magic_with(mystring) outfile.write(myreturnstring) RIGHT: mystring = infile.readline() mytext = s.decode('utf-8') returntext = do_some_magic_with(mytext) returnstring = returntext.encode('utf-8') outfile.write(returnstring) Running Tests ------------- The testing system is based on a combination of tox and testr. If you just want to run the whole suite, run `tox` and all will be fine. However, if you'd like to dig in a bit more, you might want to learn some things about testr itself.
