------------------------------------
Summary: Background retry may fall into infinite loop
Key: CURATOR-451
URL: https://issues.apache.org/jira/browse/CURATOR-451
Project: Apache Curator
Issue Type: Bug
Components: Framework
Affects Versions: 4.0.0
Reporter: Yongle Zhang
Similar to [Curator-209|https://issues.apache.org/jira/browse/CURATOR-209],
addFailedOperation() function in FailedOperationManager.java could fall into
infinite loop when there's network disruption.
Root cause: when there's an Exception (any type), function addFailedOperation()
simply recursively calls itself. And in every recursion, it prints a log.
{code:java}
void addFailedOperation(T details)
{
...
if ( client.getState() == CuratorFrameworkState.STARTED )
{
log.debug("Details being added to guaranteed operation set: " + details);
try
{
executeGuaranteedOperationInBackground(details);
}
catch ( Exception e )
{
ThreadUtils.checkInterrupted(e);
addFailedOperation(details);
}
}
}
{code}
