Example 1 with SystemAccessControl

use of io.prestosql.spi.security.SystemAccessControl in project hetu-core by openlookeng.

the class TestAccessControlManager method testColumnMaskOrdering.

@Test
public void testColumnMaskOrdering() {
    CatalogManager catalogManager = new CatalogManager();
    TransactionManager transactionManager = createTestTransactionManager(catalogManager);
    AccessControlManager accessControlManager = new AccessControlManager(transactionManager);
    accessControlManager.addSystemAccessControlFactory(new SystemAccessControlFactory() {

        @Override
        public String getName() {
            return "test";
        }

        @Override
        public SystemAccessControl create(Map<String, String> config) {
            return new SystemAccessControl() {

                @Override
                public void checkCanSetUser(Optional<Principal> principal, String userName) {
                }

                @Override
                public void checkCanImpersonateUser(Identity identity, String propertyName) {
                }

                @Override
                public void checkCanSetSystemSessionProperty(Identity identity, String propertyName) {
                }

                @Override
                public Optional<ViewExpression> getColumnMask(Identity identity, CatalogSchemaTableName tableName, String columnName, Type type) {
                    return Optional.of(new ViewExpression("user", Optional.empty(), Optional.empty(), "system mask"));
                }
            };
        }
    });
    accessControlManager.setSystemAccessControl("test", ImmutableMap.of());
    CatalogName catalogName = registerBogusConnector(catalogManager, transactionManager, accessControlManager, "catalog");
    accessControlManager.addCatalogAccessControl(catalogName, new ConnectorAccessControl() {

        @Override
        public Optional<ViewExpression> getColumnMask(ConnectorTransactionHandle transactionHandle, Identity identity, SchemaTableName tableName, String columnName, Type type) {
            return Optional.of(new ViewExpression("user", Optional.empty(), Optional.empty(), "connector mask"));
        }
    });
    transaction(transactionManager, accessControlManager).execute(transactionId -> {
        List<ViewExpression> masks = accessControlManager.getColumnMasks(transactionId, new Identity(USER_NAME, Optional.of(PRINCIPAL)), new QualifiedObjectName("catalog", "schema", "table"), "column", BIGINT);
        assertEquals(masks.get(0).getExpression(), "connector mask");
        assertEquals(masks.get(1).getExpression(), "system mask");
    });
}

Example 2 with SystemAccessControl

use of io.prestosql.spi.security.SystemAccessControl in project hetu-core by openlookeng.

the class AccessControlManager method setSystemAccessControl.

@VisibleForTesting
protected void setSystemAccessControl(String name, Map<String, String> properties) {
    requireNonNull(name, "name is null");
    requireNonNull(properties, "properties is null");
    checkState(systemAccessControlLoading.compareAndSet(false, true), "System access control already initialized");
    log.info("-- Loading system access control --");
    SystemAccessControlFactory systemAccessControlFactory = systemAccessControlFactories.get(name);
    checkState(systemAccessControlFactory != null, "Access control %s is not registered", name);
    SystemAccessControl tmpSystemAccessControl = systemAccessControlFactory.create(ImmutableMap.copyOf(properties));
    this.systemAccessControl.set(tmpSystemAccessControl);
    log.info("-- Loaded system access control %s --", name);
