Toru Matsuzawa commented on SOLR-214:
-------------------------------------
This problem can be confirmed with tomcat 5.5.23.
This problem had occurred by "/update" before the correction of SOLR-197.
stream.getReader() is acquired by org.apache.catalina.connector.CoyoteReader.
CoyoteReader use org.apache.catalina.connector.InputBuffer#realReadBytes().
realReadBytes() is read with byte order.
Therefore, garbled characters in the index.
> deficit of InputStreamReader support in anonymous class of ContentStream

> Key: SOLR-214
> URL: https://issues.apache.org/jira/browse/SOLR-214
> Project: Solr
> Issue Type: Bug
> Reporter: Koji Sekiguchi
> Attachments: UseInputStreamReader.patch
>
>
> After SOLR-197 is applied, POSTed Japanese XML contents turn into garbled
> characters in the index.
> I can see the garbled characters through Luke. The issue was never seen
> before SOLR-197.
> The cause of this problem is that the deficit of InputStreamReader support in
> the anonymous class of ContentStream in
> SolrRequestParsers.parseParamsAndFillStreams() method.
> Before SOLR-197, InputStreamReader was used in
> XmlUpdateRequestHandler.handleRequestBody() method:
> // Cycle through each stream
> for( ContentStream stream : req.getContentStreams() ) {
> String charset = getCharsetFromContentType( stream.getContentType() );
> Reader reader = null;
> if( charset == null ) {
> reader = new InputStreamReader( stream.getStream() );
> }
> else {
> reader = new InputStreamReader( stream.getStream(), charset );
> }
> rsp.add( "update", this.update( reader ) );
>
> // Make sure its closed
> try { reader.close(); } catch( Exception ex ){}
> }
> The patch will apply this effect to SolrRequestParsers.
> regards,
