Simon McNaughton updated JCR-3252:

    Affects Version/s:     (was: 2.1.6)
> 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: 2.5.1
>            Reporter: Simon McNaughton
>            Priority: Minor
>         Attachments: QueryResultImp_3252.patch
> 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.
