Dag H. Wanvik updated DERBY-3722:
---------------------------------
Attachment: derby-3722-3.stat
derby-3722-3.diff
I made a new version of the patch, derby-3722-3, which lets the
iterator's 'next' method return a role name string instead of the
RoleGrantDescriptor in the graph. This simplifies usage.
I also fixed the typo pointed out by Rick, and started using
BaseTestCase#fail in RolesTest where exception chaining is
useful.
Version 2 of the patch passed regression tests, so I expect this one
to it as well, although not finished yet.

> When a role is granted to another role (with the GRANT <role> statement), we
> need to check that the grant relation does not give rise to a circularity.
> This is described in Section 12.5, Syntax rule 1 of ISO/IEC 9075-2 2003.
