Subject [jira] [Created] (SOLR-3787) Compress (internal) parameter mismatch
Date Wed, 05 Sep 2012 00:09:08 GMT
Joseph Lamoree created SOLR-3787:
------------------------------------

             Summary: Compress (internal) parameter mismatch
                 Key: SOLR-3787
                 URL: https://issues.apache.org/jira/browse/SOLR-3787
             Project: Solr
          Issue Type: Bug
          Components: replication (java)
    Affects Versions: 4.0-BETA
         Environment: N/A
            Reporter: Joseph Lamoree
            Priority: Minor


In the following commit, the value of the parameter set in SnapPuller changed from "true"
to "internal":

http://svn.apache.org/viewvc/lucene/dev/trunk/solr/core/src/java/org/apache/solr/handler/SnapPuller.java?r1=1353888&r2=1353889&

Specifically, this line:
  formparams.add(new BasicNameValuePair(COMPRESSION, "true"));
Was changed to this:
  params.set(COMPRESSION, "internal"); 

When the ReplicationHandler tests the value sent in the query string, it uses Boolean.parseBoolean()
and expects the string "true". I created a packet capture, watching the slave make a request
of the master. The transfer of files fails when my solrconfig.xml has a slave configuration
like this:
  <str name="compression">internal</str>

An exception is thrown on the slave because it is expecting a compressed response from the
following:
  /solr/core/replication?command=filecontent&generation=N ...  &compression=internal&checksum=true&wt=filestream

When I manually make the above request, replacing compression=internal with compression=true,
the expected compressed response is received from the master.
