Subject [jira] Commented: (DERBY-1330) Provide runtime privilege checking for grant/revoke functionality
Date Wed, 19 Jul 2006 03:31:15 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1330?page=comments#action_12422021 ] 
            
Andrew McIntyre commented on DERBY-1330:
----------------------------------------

Committed DERBY-1330javaDocWarningsDiffV9.txt patch to trunk with revision 423352. Note that
in two cases, the @param privType actually needed to be privTypeStr to match the name of the
parameter.

> 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.
