From 25c8a555a739b1c80966ed88cc123a6e9ad9318e Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Mon, 31 Aug 2020 17:59:44 -0400 Subject: Allow guards to be dynamically enabled/disabled Modified drools-apps so that guards can be dynamically enabled and disabled. Due to the current design, there are two properties that control this: - an actor-level property: when enabled, the DB connection is created, otherwise a stub connection is created. This property is NOT dynamic - an engine-level property: when enabled, the connection created by the actor is used, otherwise a stub connection is used. This property IS dynamic Issue-ID: POLICY-2748 Change-Id: I2a5baf908ce274f2eb46a6a3f01df1b3532038ff Signed-off-by: Jim Hahn --- .../eventmanager/ControlLoopEventManager.java | 16 +++++++++++++--- .../eventmanager/ControlLoopEventManagerTest.java | 17 +++++++++++++++++ 2 files changed, 30 insertions(+), 3 deletions(-) (limited to 'controlloop/common/eventmanager/src') diff --git a/controlloop/common/eventmanager/src/main/java/org/onap/policy/controlloop/eventmanager/ControlLoopEventManager.java b/controlloop/common/eventmanager/src/main/java/org/onap/policy/controlloop/eventmanager/ControlLoopEventManager.java index 12128554f..248a41be6 100644 --- a/controlloop/common/eventmanager/src/main/java/org/onap/policy/controlloop/eventmanager/ControlLoopEventManager.java +++ b/controlloop/common/eventmanager/src/main/java/org/onap/policy/controlloop/eventmanager/ControlLoopEventManager.java @@ -41,6 +41,7 @@ import org.onap.policy.controlloop.actorserviceprovider.ActorService; import org.onap.policy.controlloop.actorserviceprovider.OperationOutcome; import org.onap.policy.controlloop.drl.legacy.ControlLoopParams; import org.onap.policy.controlloop.ophistory.OperationHistoryDataManager; +import org.onap.policy.controlloop.ophistory.OperationHistoryDataManagerStub; import org.onap.policy.controlloop.processor.ControlLoopProcessor; import org.onap.policy.drools.core.lock.LockCallback; import org.onap.policy.drools.system.PolicyEngineConstants; @@ -59,6 +60,12 @@ public class ControlLoopEventManager implements StepContext, Serializable { private static final Logger logger = LoggerFactory.getLogger(ControlLoopEventManager.class); private static final long serialVersionUID = -1216568161322872641L; + /** + * Data manager used when the policy engine's guard.disabled property is "true". + */ + private static final OperationHistoryDataManager STUB_DATA_MANAGER = new OperationHistoryDataManagerStub(); + + private static final String GUARD_DISABLED_PROPERTY = "guard.disabled"; private static final String EVENT_MANAGER_SERVICE_CONFIG = "event-manager"; /** @@ -269,8 +276,6 @@ public class ControlLoopEventManager implements StepContext, Serializable { private static final ActorService ACTOR_SERVICE; static { - // TODO how to dynamically change data manager, depending whether or not - // guards are enabled?
