Subject [jira] Updated: (SOLR-2162) TestLBHttpSolrServer.testSimple test failure
Date Sun, 17 Oct 2010 13:33:22 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2162?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Muir updated SOLR-2162:
------------------------------

    Attachment: SOLR-2162_test.patch

I think this might be a real bug in the retry handling of the CommonsHttpSolrServer:
I suspect a reuse bug where in the finally block in the loop, releaseConnection() is called
but the same option is later reused (a new Method is not created)

attached is a patch to reproduce the failure.
The test fails most of the time, but to be sure run like this:

ant test-core -Dtestcase=TestLBHttpSolrServer -Dtestmethod=testReliability -Dtests.iter=10

it also creates other interesting wonderful exceptions such as:
{noformat}
    [junit] Caused by: org.apache.solr.client.solrj.SolrServerException: org.apache.commons.httpclient.ProtocolException
: Unable to parse header: vr et(..2
{noformat}
