Carsten Ziegeler commented on SLING-8407: ----------------------------------------- [~tmueller] I think you're misinterpreting my statements; I prefer catching bugs at test time instead of at runtime through runtime exceptions; but I think discussing this here doesn't lead us anywhere. I also have a totally different opinion on the whole subject and the suggested solution is spreading code pieces across a lot of modules; it's also based on looking at a single usage pattern. Anyways, I've said what I wanted to say, you still want to continue your way. That's fine, I'm not blocking things here > JobManagerImpl.findJobs should prevent traversal > ------------------------------------------------ > > Key: SLING-8407 > URL: https://issues.apache.org/jira/browse/SLING-8407 > Project: Sling > Issue Type: Improvement > Components: Event > Reporter: Thomas Mueller > Priority: Major > > The method > [JobManagerImpl.findJobs|https://github.com/apache/sling-org-apache-sling-event/blob/master/src/main/java/org/apache/sling/event/impl/jobs/JobManagerImpl.java#L373] > runs a JCR query to find all jobs for a topic. > It is possible that such a query is running while the repository isn't > initialized yet, meaning while the index isn't available yet. What is > happening in this case is that the query is traversing all nodes below that > path, triggering a warning that the query doesn't use an index. It is > sometimes happening when a health check is running before the repository is > initialized (ReplicationQueueHealthCheck and DistributionQueueHealthCheck). > It doesn't make sense that the query traverses the nodes. It should use an > index. If the index isn't available yet, it should fail. Therefore, the query > should use "option(traversal fail)". That would result in an exception that > can be caught. I will log a related issue to change the health checks to > process this exception and return HEALTH_CHECK_ERROR for this case. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
