Actually, I disagree. The real problem here is the definition of
bar_func(). The default value of the parameter "arg" will likely always
be the default value of foo_opt, rather than the configured value,
because "CONF.foo_opt" will be evaluated at module load time. The way
bar_func() should be defined would be:
def bar_func(arg=None):
if not arg:
arg = CONF.foo_opt
…
That ensures that arg will be the configured value, and should also
solve the import conflict.
Surely you mean:
if arg is not None:
right?! I'm pretty sure there is a hacking check for that now too...
