-----------------------------------
Summary: PropertyIndex uses TraversingCursor but should not
Key: JCR-3460
URL: https://issues.apache.org/jira/browse/JCR-3460
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: query
Reporter: Thomas Mueller
Assignee: Thomas Mueller
The org.apache.jackrabbit.oak.plugins.index.property.PropertyIndex uses the
traversing cursor (that traverses over the whole repository) when there is no
index. This is not how the index mechanism is supposed to work: if there is no
property index, then the cost function of the property index should return
infinity or max value, so that the property index isn't used.
According to my test the PropertyIndex never really falls back to traversing,
so this might just be "defensive programming". However, in this case it would
be better if the code would throw an exception, otherwise we risk not seeing
the bug in the PropertyIndex cost method.
