Carl Yeksigian commented on CASSANDRA-12925:
--------------------------------------------
Code looks good, and I think I understand why we can't use the {{ClientState}},
but just to make sure: it's because of the way we share the permissions
statements between resources.
That is, if we had a {{GrantFunctionPermissionsStatement}}, we could add a new
interface {{KeyspacedStatement}} (or something) which would use the
{{ClientState}} as in {{CFStatement}}.

> Key: CASSANDRA-12925
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12925
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Reporter: Sam Tunnicliffe
> Assignee: Sam Tunnicliffe
> Priority: Minor
> Fix For: 2.2.x, 3.0.x, 3.x
>
>
> Performing a {{GRANT}} or {{REVOKE}} on a user defined function requires the
> function name to be qualified by its keyspace. Unlike {{GRANT/REVOKE}} on a
> table, the keyspace cannot be inferred from the {{ClientState}} as it's
> needed by the parser to either lookup the function (in 2.2), or convert the
> function arguments from CQL types to their corresponding {{AbstractType}} (in
> 3.0+).
> Currently, performing such a statement results in an unhandled assert error
> and a {{ServerError}} response to the client.
