Subject [jira] Updated: (SOLR-1543) StreamingUpdateSolrServer threading bug
Date Fri, 06 Nov 2009 00:57:32 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1543?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Yonik Seeley updated SOLR-1543:
-------------------------------

    Attachment: SOLR-1543.patch

This patch most likely does not fix the problem (I don't even know how to reproduce the problem
at this point).  But it does:
 - unlock the lock in a finally block
 - fix thread visibility of the lock by making it volatile
 - change the lock in each runner to be a countdown latch since the only purpose appears to
be to wait for the runner to stop.  This fixes a race condition where previously the lock/unlock
pair in blockUntilFinished() could possibly execute *before* the runner itself locks the lock.

There are other race conditions and thread safety problems I see, but I'm not sure if any
are serious or not.
