Subject [jira] [Created] (SOLR-3857) DIH: SqlEntityProcessor with "simple" cache broken
Date Wed, 19 Sep 2012 15:49:07 GMT
James Dyer created SOLR-3857:
--------------------------------

             Summary: DIH: SqlEntityProcessor with "simple" cache broken
                 Key: SOLR-3857
                 URL: https://issues.apache.org/jira/browse/SOLR-3857
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.0-BETA, 3.6.1
            Reporter: James Dyer


The wiki describes a usage of CachedSqlEntityProcessor like this:

{code:xml}
<entity name="y" query="select * from y where xid=${x.id}" processor="CachedSqlEntityProcessor">
{code}

This creates what the code refers as a "simple" cache.  Rather than build the entire cache
up-front, the cache is built on-the-go.  I think this has limited use cases but it would be
nice to preserve the feature if possible.

Unfortunately this was not included in any (effective) unit tests, and SOLR-2382 entirely
broke the functionality for 3.6/4.0-alpha+ .  At a first glance, the fix may not be entirely
straightforward.

This was found while writing tests for SOLR-3856.
