Text encoding
All text within python code should be of type 'unicode'.
WRONG:
>>> s = 'foo' >>> s 'foo' >>> type(s) <type 'str'>
RIGHT:
>>> u = u'foo' >>> u u'foo' >>> type(u) <type 'unicode'>
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. A basic walkthrough for OpenStack can be found at http://wiki.openstack.org/testr
