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
