Comment (by dmr):

 [comment:6 Quoting dmr]:
 > ==== 1. Failure for `GETINFO exit-policy/full` to return info.
 > [...]
 >
 > I've noticed two circumstances in which the exit-policy is unqueryable:
 > * [...]
 > * tor is configured as a client
 >
 > The former is [...]
 > The latter is persistent, i.e. the client-only configuration ALWAYS
 returns this:
 > {{{
 > >>> GETINFO exit-policy/full
 > 551 router_get_my_routerinfo returned NULL
 > }}}
 >
 > `Controller.get_exit_policy()` has the `default` parameter. Without
 specifying a default, `get_exit_policy()` will raise an exception in these
 cases.
