----------------------------------
Resolution: Fixed
Fix Version/s: 1.7.11
> Lucene unique index should check path validity for uniqueness constraint
> ------------------------------------------------------------------------
>
> Key: OAK-6857
> URL: https://issues.apache.org/jira/browse/OAK-6857
> Project: Jackrabbit Oak
> Issue Type: Technical task
> Components: lucene
> Reporter: Chetan Mehrotra
> Assignee: Chetan Mehrotra
> Fix For: 1.8, 1.7.11
>
>
> The {{UniquenessConstraintValidator}} currently checks for any new index entry if any matching entry is found in primary (property) and secondary (lucene) index.
> This can lead to false positive where the entry in index is obsolete and due to async index lagging behind is yet not pruned. For e.g. if
> # Time T1 - path /a/@uuid=1 existed , present in lucene index
> # Time T2 - path /a removed (async index yet not catched up)
> # Time T3 - path /b/@uuid=1 being created.
> In this case save should pass. However as async index has yet not catched up it reports a constraint validation exception. As a fix {{UniquenessConstraintValidator}} should check if reported paths are valid wrt current revision
