Mamta A. Satoor commented on DERBY-1330:
----------------------------------------
Based on Dan's feedback on QueryNode, I am proposing the method name to be
changed from "isExecutingWithInvokerPrivileges" to
"isPrivilegeCollectionRequired". I tend to get too verbose with my method
names, so if anyone has another suggestion for more appropriate method name,
please suggest so. As for the comments for that method, I am suggesting
following
/**
* Return true from this method means that we need to collect privilege
* requirement for this node. For following cases, this method will
* return true.
* 1)execute view - collect privilege to access view but do not collect
* privilege requirements for objects accessed by actual view uqery
* 2)execute select - collect privilege requirements for objects
accessed
* by select statement
* 3)create view - collect privileges for select statement : the
select
* statement for create view falls under 2) category above.
*
* @return true if need to collect privilege requirement for this node
*/
> Provide runtime privilege checking for grant/revoke functionality

> Additional work needs to be done for grant/revoke to make sure that only
> users with required privileges can access various database objects. In order
> to do that, first we need to collect the privilege requirements for various
> database objects and store them in SYS.SYSREQUIREDPERM. Once we have this
> information then when a user tries to access an object, the required
> SYS.SYSREQUIREDPERM privileges for the object will be checked against the
> user privileges in SYS.SYSTABLEPERMS, SYS.SYSCOLPERMS and
> SYS.SYSROUTINEPERMS. The database object access will succeed only if the user
> has the necessary privileges.
> SYS.SYSTABLEPERMS, SYS.SYSCOLPERMS and SYS.SYSROUTINEPERMS are already
> populated by Satheesh's work on DERBY-464. But SYS.SYSREQUIREDPERM doesn't
> have any information in it at this point and hence no runtime privilege
> checking is getting done at this point.
