Inflated QueryResultsImpl getTotalSize Count
--------------------------------------------
Key: JCR-3252
URL: https://issues.apache.org/jira/browse/JCR-3252
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 2.1.6
Reporter: Simon McNaughton
Priority: Minor
The results of the method getTotalSize() in class
org.apache.jackrabbit.core.query.lucene.QueryResultImpl appear to sometimes be
inflated.
The method getTotalSize() returns the number of results of the
query(numResults) minus the number of results that the accessManager has not
allowed access to (invalid). The value of invalid appears to be determined
during the method collectScoreNodes.
The issue is that 'invalid' doesn't appear to accurately reflect the total
number of results of the orginal query that the user is not allowed access to,
resulting in an incorrect value for getTotalSize().
The cause of this appears to be in method collectScoreNodes because it will
only check nodes to see if they are invalid while it is looking for the first
'maxResultSize' valid nodes. Any nodes after that limit are not checked for
validity. This may result in a number of nodes that are invalid, but have not
recorded as such. Then because the limit variable doesn't reflect the actual
number of invalid results, the getTotalSize() value is inflated.
