[PATCH] Check if permission exists before creating it
I've changed AbstractStore.grantPermission() to check whether a
permission exists before creating it. I'm not sure whether that's the
appropriate place for the check, though.
(I can't currently connect to the jakarta cvs-pserver for some reason,
so I'm including the actual code here instead of a diff, sorry.)
src/share/org/apache/slide/store/AbstractStore.java, line 576ff
================================================================
public void grantPermission(Uri uri, NodePermission permission)
throws ServiceAccessException {
NodePermission tempPermission = permission.cloneObject();
tempPermission.validate(uri.toString());
// Checking if the permission is already present
Enumeration permissions = enumeratePermissions(uri);
while (permissions.hasMoreElements()) {
if (tempPermission.equals(permissions.nextElement())) {
return;
}
}
// Not present yet, so create it
enlist(securityStore);
try {
securityStore.grantPermission(uri, tempPermission);
} catch (ServiceAccessException e) {
delist(securityStore, false);
throw e;
}
delist(securityStore);
}
