Sylvain Lebresne updated CASSANDRA-6643:
----------------------------------------
Attachment: 6643.txt
First attaching a patch to only allow referencing user types in the keyspace
they are defined in.
Still not entirely convinced that the behavior described above is the best
choice. It's not illogical, but I wonder if saying "non qualified type and
table names always refer to the logged keyspace" wouldn't be simpler that "non
qualified table name refers to the logged keyspace, and so do type name, except
when they are inside a statement in which case they refer to the statement
keyspace".
> Limit user types to the keyspace they are defined in

> I'm not 100% certain this is a bug.
> The current syntax for "alter type rename" requires the keyspace on the old
> and new table name (if a keyspace is not active). So, to rename the type
> 'foo' to 'bar', you have to issue this statement:
> ALTER TYPE ks.foo rename to ks.bar .
> As a result, this syntax will also allow renaming the type into another
> existing keyspace, which updates the metadata in system.schema_usertypes.
> I'm wondering if perhaps we can omit the second keyspace prefix and
> implicitly rename into the same keyspace.
> To reproduce:
> {noformat}
> cqlsh> create keyspace user_types with replication =
> {'class':'SimpleStrategy', 'replication_factor':3} ;
> cqlsh> create keyspace user_types2 with replication =
> {'class':'SimpleStrategy', 'replication_factor':3} ;
> cqlsh> CREATE TYPE user_types.simple_type (user_number int);
> cqlsh> alter type user_types.simple_type rename to user_types2.simple_type;
> {noformat}
> Renaming to another keyspace is also possible when a keyspace is active, like
> so:
> {noformat}
> cqlsh:user_types> alter type simple_type rename to user_types2.simple_type;
> {noformat}
