This happens when I getModifiedChildren on a DataObjectModification and call getModificationType on one of the modified children. Why would this happen?</p> <p>2016-03-05 00:15:12.844 GMT+00:00 <span class="error">&#91;opendaylight-cluster-data-notification-dispatcher-54&#93;</span> ERROR o.o.c.c.d.DataTreeChangeListenerActor - Error notifying listener org.opendaylight.controller.md.sal.binding.impl.BindingClusteredDOMDataTreeChangeListenerAdapter@79048d7e<br/> java.lang.IllegalStateException: Unsupported DOM Modification type UNMODIFIED<br/> at org.opendaylight.controller.md.sal.binding.impl.LazyDataObjectModification.getModificationType(LazyDataObjectModification.java:150) <span class="error">&#91;na:na&#93;</span><br/> at com.cisco.osc.application.MyListener.onDataTreeChanged(MyListener.java:106) <span class="error">&#91;com.cisco.osc.application.my-provider:0.1.2.Lithium-SR2-00003-1000&#93;</span><br/> at org.opendaylight.controller.md.sal.binding.impl.BindingDOMDataTreeChangeListenerAdapter.onDataTreeChanged(BindingDOMDataTreeChangeListenerAdapter.java:41) <span class="error">&#91;na:na&#93;</span><br/> at org.opendaylight.controller.cluster.datastore.DataTreeChangeListenerActor.dataChanged(DataTreeChangeListenerActor.java:53) <span class="error">&#91;org.opendaylight.controller.sal-distributed-datastore:1.2.2.Lithium-SR2-00003-865&#93;</span><br/> at org.opendaylight.controller.cluster.datastore.DataTreeChangeListenerActor.handleReceive(DataTreeChangeListenerActor.java:37) <span class="error">&#91;org.opendaylight.controller.sal-distributed-datastore:1.2.2.Lithium-SR2-00003-865&#93;</span><br/> at org.opendaylight.controller.cluster.common.actor.AbstractUntypedActor.onReceive(AbstractUntypedActor.java:34) <span class="error">&#91;org.opendaylight.controller.sal-clustering-commons:1.2.2.Lithium-SR2-00003-865&#93;</span><br/> at akka.actor.UntypedActor$$anonfun$receive$1.applyOrElse(UntypedActor.scala:167) <span class="error">&#91;com.typesafe.akka.actor:2.3.10&#93;</span><br/> at akka.actor.Actor$class.aroundReceive(Actor.scala:467) <span class="error">&#91;com.typesafe.akka.actor:2.3.10&#93;</span><br/> at akka.actor.UntypedActor.aroundReceive(UntypedActor.scala:97) <span class="error">&#91;com.typesafe.akka.actor:2.3.10&#93;</span><br/> at akka.actor.ActorCell.receiveMessage(ActorCell.scala:516) <span class="error">&#91;com.typesafe.akka.actor:2.3.10&#93;</span><br/> at akka.actor.ActorCell.invoke(ActorCell.scala:487) <span class="error">&#91;com.typesafe.akka.actor:2.3.10&#93;</span><br/> at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:254) <span class="error">&#91;com.typesafe.akka.actor:2.3.10&#93;</span><br/> at akka.dispatch.Mailbox.run(Mailbox.scala:221) <span class="error">&#91;com.typesafe.akka.actor:2.3.10&#93;</span><br/> at akka.dispatch.Mailbox.exec(Mailbox.scala:231) <span class="error">&#91;com.typesafe.akka.actor:2.3.10&#93;</span><br/> at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) <span class="error">&#91;org.scala-lang.scala-library:2.10.4.v20140209-180020-VFINAL-b66a39653b&#93;</span><br/> at scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) <span class="error">&#91;org.scala-lang.scala-library:2.10.4.v20140209-180020-VFINAL-b66a39653b&#93;</span><br/> at scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) <span class="error">&#91;org.scala-lang.scala-library:2.10.4.v20140209-180020-VFINAL-b66a39653b&#93;</span><br/> at scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) <span class="error">&#91;org.scala-lang.scala-library:2.10.4.v20140209-180020-VFINAL-b66a39653b&#93;</span></p> <p>Operating System: All<br/> Platform: All</p> MDSAL-134

Bug Resolved Cannot Reproduce Unassigned Moiz Raja Tue, 8 Mar 2016 01:24:23 +0000 Sat, 4 Aug 2018 01:40:58 +0000 Sat, 4 Aug 2018 01:40:58 +0000 Binding runtime 0 7 <p>Effectivelly it means BindingDataTreeChangeListener received from clustering DataTreeCandidateNode with UNMODIFIED which means listener was triggered even if data were not modified.</p> <p>I assume that can happen if a client wrote the same data?</p> <p>I think the bug is not in the generating of the notification but in the implementation of LazyDataObjectModification#getModifiedChildren(). It should not return a child which has the modificationType UNMODIFIED. </p> <p>This is happening in my specific implementation when I listen at a top-level node and when I get a data tree change I navigate the modification tree to figure out whether a specific subtree change happened.</p> <p>DTCL does not perform a comparison of the actual data, so an overwrite with the same data still shows up as WRITE.</p> <p>Does this still happen with Boron/Carbon? Do we have a unit test?</p> <p>I haven't seen this exception. It doesn't appear there's any test case available at this point.</p> <p>I am using BE SR3 and I see this exception<br/> java.lang.IllegalStateException: Unsupported DOM Modification type UNMODIFIED</p> <p>It happens with Boron-SR2 too.</p> <p>We will need at least some data on what the model/DS operation triggering this is, otherwise we can only guess as to what is going on.</p> Development External issue ID 5468 External issue URL Rank 0|i02wiv:
