Alex Rudyy created QPID-8342: -------------------------------- Summary: [Broker-J] Concurrent object creation with virtual host auto-creation policy can fail Key: QPID-8342 URL: https://issues.apache.org/jira/browse/QPID-8342 Project: Qpid Issue Type: Bug Components: Broker-J Affects Versions: qpid-java-broker-7.1.4, qpid-java-broker-7.1.3, qpid-java-broker-7.0.8, qpid-java-broker-7.1.2, qpid-java-broker-7.1.1, qpid-java-broker-7.0.7, qpid-java-broker-7.0.6, qpid-java-broker-7.0.5, qpid-java-broker-7.0.4, qpid-java-broker-7.1.0, qpid-java-6.1.7, qpid-java-broker-7.0.1, qpid-java-broker-7.0.0 Reporter: Alex Rudyy Fix For: qpid-java-broker-7.1.5
When the same non-existing object is requested from multiple connections (for example, on receiving multiple link attach performatives) and matching auto-creation policy creates the object, the failures can be reported on some of the incoming requests due to {{DuplicateNameException}}. The following stack trace ican bereported into the broker logs for the impacted connections: {noformat} INFO [IO-/0:0:0:0:0:0:0:1:35050] (o.a.q.s.v.AbstractVirtualHost) - Unable to auto create a node named foo due to exception org.apache.qpid.server.model.AbstractConfiguredObject$DuplicateNameException: Child of type StandardQueueImplWithAccessChecking already exists with name of foo return node; at org.apache.qpid.server.model.AbstractConfiguredObject.registerChild(AbstractConfiguredObject.java:2131) at org.apache.qpid.server.model.AbstractConfiguredObject.registerWithParents(AbstractConfiguredObject.java:689) at org.apache.qpid.server.model.AbstractConfiguredObject$6.execute(AbstractConfiguredObject.java:882) at org.apache.qpid.server.model.AbstractConfiguredObject$6.execute(AbstractConfiguredObject.java:868) at org.apache.qpid.server.model.AbstractConfiguredObject$2.execute(AbstractConfiguredObject.java:639) at org.apache.qpid.server.model.AbstractConfiguredObject$2.execute(AbstractConfiguredObject.java:632) at org.apache.qpid.server.configuration.updater.TaskExecutorImpl$TaskLoggingWrapper.execute(TaskExecutorImpl.java:248) at org.apache.qpid.server.configuration.updater.TaskExecutorImpl.submitWrappedTask(TaskExecutorImpl.java:165) at org.apache.qpid.server.configuration.updater.TaskExecutorImpl.submit(TaskExecutorImpl.java:153) at org.apache.qpid.server.model.AbstractConfiguredObject.doOnConfigThread(AbstractConfiguredObject.java:631) at org.apache.qpid.server.model.AbstractConfiguredObject.createAsync(AbstractConfiguredObject.java:867) at org.apache.qpid.server.model.AbstractConfiguredObjectTypeFactory.createAsync(AbstractConfiguredObjectTypeFactory.java:75) at org.apache.qpid.server.queue.QueueFactory.createAsync(QueueFactory.java:58) at org.apache.qpid.server.model.ConfiguredObjectFactoryImpl.createAsync(ConfiguredObjectFactoryImpl.java:145) at org.apache.qpid.server.model.AbstractConfiguredObject.addChildAsync(AbstractConfiguredObject.java:2113) at org.apache.qpid.server.virtualhost.AbstractVirtualHost.addChildAsync(AbstractVirtualHost.java:864) at org.apache.qpid.server.model.AbstractConfiguredObject$17.execute(AbstractConfiguredObject.java:2070) at org.apache.qpid.server.model.AbstractConfiguredObject$17.execute(AbstractConfiguredObject.java:2065) at org.apache.qpid.server.model.AbstractConfiguredObject$2.execute(AbstractConfiguredObject.java:639) at org.apache.qpid.server.model.AbstractConfiguredObject$2.execute(AbstractConfiguredObject.java:632) at org.apache.qpid.server.configuration.updater.TaskExecutorImpl$TaskLoggingWrapper.execute(TaskExecutorImpl.java:248) at org.apache.qpid.server.configuration.updater.TaskExecutorImpl$CallableWrapper$1.run(TaskExecutorImpl.java:320) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:360) at org.apache.qpid.server.configuration.updater.TaskExecutorImpl$CallableWrapper.call(TaskExecutorImpl.java:313) at com.google.common.util.concurrent.TrustedListenableFutureTask$TrustedFutureInterruptibleTask.runInterruptibly(TrustedListenableFutureTask.java:125) at com.google.common.util.concurrent.InterruptibleTask.run(InterruptibleTask.java:57) at com.google.common.util.concurrent.TrustedListenableFutureTask.run(TrustedListenableFutureTask.java:78) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at org.apache.qpid.server.bytebuffer.QpidByteBufferFactory.lambda$null$0(QpidByteBufferFactory.java:464) at java.lang.Thread.run(Thread.java:748) {noformat} The object creation with auto-creation policy should handle {{DuplicateNameException}} on attempt to create the same object which has been already created concurrently. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
