Subject [jira] [Created] (SOLR-3829) Admin UI Logging events broken if schema.xml defines a catch-all dynamicField with type ignored
Date Wed, 12 Sep 2012 11:43:10 GMT
Andreas Hubold created SOLR-3829:
------------------------------------

             Summary: Admin UI Logging events broken if schema.xml defines a catch-all dynamicField
with type ignored
                 Key: SOLR-3829
                 URL: https://issues.apache.org/jira/browse/SOLR-3829
             Project: Solr
          Issue Type: Bug
          Components: web gui
    Affects Versions: 4.0-BETA
            Reporter: Andreas Hubold


The Solr Admin page does not show any log events. There are Javascript errors

{noformat}
TypeError: doc.logger.esc is not a function
... '<abbr title="' + doc.logger.esc() + '">' + doc.logger.split( '.' ).pop().esc()...
{noformat}

This is because the response of the LoggingHandler added unexpected {{[ ... ]}} characters
around the values for time, level, logger and message:

{noformat}
...
"history":{"numFound":2,"start":0,"docs":[{"time":["2012-09-11T15:07:05.453Z"],"level":["WARNING"],"logger":["org.apache.solr.core.SolrCore"],"message":["New
index directory detected: ...
{noformat}

This is caused by the way the JSON is created. org.apache.solr.logging.LogWatcher#toSolrDocument
creates a SolrDocument which is then formatted with a org.apache.solr.response.JSONResponseWriter.
But the JSONResponseWriter uses the index schema to decide how to format the JSON. We have
the following field declaration in schema.xml:

{noformat}
    <dynamicField name="*" type="ignored" />
{noformat}

The field type "ignored" has the attribute multiValued set to true. Because of this JSONResponseWriter
adds [] characters in org.apache.solr.response.JSONWriter#writeSolrDocument

The formatting should be independent from schema.xml
