Cameron McKenzie commented on CURATOR-228:
------------------------------------------
I've looked into this a bit more and I'm wondering whether the way forward may
be to allow calls to the CuratorFramework's builder methods to specify a set of
error codes that they would like the operation to be retried on (in addition to
the ones already hard coded into the RetryLoop).
This would allow the current case to be handled by just specifying that the
NOAUTH case should be retried. Thoughts?
> A serious death cycle error(一个严重的死循环错误)
> ---------------------------------------

> Key: CURATOR-228
> URL: https://issues.apache.org/jira/browse/CURATOR-228
> Project: Apache Curator
> Issue Type: Bug
> Components: Framework
> Affects Versions: 2.7.0, 2.7.1, 2.8.0
> Environment: windows linux mac ....
> Reporter: coder_czp
> Assignee: Cameron McKenzie

> 当用异步的方式创建带有多层目录的临时节点时，如果客户端没有zookeeper的写入权限，curator
> 就会陷入死循环,客户端会一直向服务器提交写入报文，但是永远不会成功。出错的代码逻辑如下:
> When used asynchronous way to create a temporary node multi directory, if the
> client does not have the zookeeper write permissions, the curator will get
> into a cycle of death, the client will has been submitted to the server write
> message, but never succeed. Error code logic is as follows:
> 1 PersistentEphemeralNode sessionNode = new
> PersistentEphemeralNode(curatorClient, Mode.EPHEMERAL,"/a/b/c", "test");
> sessionNode.start();
> CreateBuilderImpl:
> forPath(xx)-->pathInBackground(xx)-->
>
> CuratorFrameworkImpl:processBackgroundOperation(operationAndData, null);
>
> --->performBackgroundOperation(xx)
>
> OperationAndData:callPerformBackgroundOperation(xx)-->
>
> CreateBuilderImpl:performBackgroundOperation(xx)->backgroundCreateParentsThenNode(xx)
>
> -->queueOperation(xx){backgroundOperations.offer(operationAndData);}
>
> //这个循环会触发1，导致循环无法退出
> //This cycle will trigger 1, causing the loop to exit.
> //CuratorFrameworkImpl
> 2 private void backgroundOperationsLoop()
> {
> while ( !Thread.currentThread().isInterrupted() )
> {
> OperationAndData<?> operationAndData;
> try
> {
> operationAndData = backgroundOperations.take();
> if ( debugListener != null )
> {
> debugListener.listen(operationAndData);
> }
> }
> catch ( InterruptedException e )
> {
> Thread.currentThread().interrupt();
> break;
> }
> performBackgroundOperation(operationAndData);
> }
> }
