[jira] [Updated] (JCR-3402) getSize() returning too many often -1

["Cédric Damioli (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/JCR-3402?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Cédric Damioli updated JCR-3402:
--------------------------------

    Attachment: QueryResultImpl.java.patch

Attached is a proposal that aims to return the real size instead of -1 in certain cases.

All tests pass with this patch, but unfortunately there's not many tests testing for getSize()

It would be great if a query expert could review this small patch to see if I haven't broken anything
Thanks

> I've came accross the well known behaviour of query results returning -1 when asked for getSize().
> While this is ok for optimization reasons (lazy results fetching), I just discovered that the default "resultFetchSize" value in lucene queries is Integer.MAX_VALUE, so in all queries I've ever executed, all results were actually fetched before asking for getSize, so IMHO nothing prevents getSize() to return the real value instead -1
