    [ https://issues.apache.org/jira/browse/SOLR-670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12639775#action_12639775 ] 

Shalin Shekhar Mangar commented on SOLR-670:
--------------------------------------------

Thanks for the patch Koji. Updated with a few changes:

# CSVRequestHandler#handleRequestBody should call handleRollback if streams is null just like it calls handleCommit
# XmlUpdateRequestHandler#handleRequestBody should call handleRollback if streams is null just like it calls handleCommit

Let us think about SolrEventListener changes if users ask for it. Off hand, I can't think of a use-case.

I shall commit this shortly.
