Subject [jira] [Commented] (SOLR-4196) Untangle XML-specific nature of Config and Container classes
Date Thu, 28 Mar 2013 17:07:15 GMT

    [ https://issues.apache.org/jira/browse/SOLR-4196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13616427#comment-13616427
] 

Mark Miller commented on SOLR-4196:
-----------------------------------

what im talking about is this:

{code}
  // We are shutting down. We don't want to risk deadlock, so do this manipulation the expensive
way. Note, I've
  // already deadlocked with closing/opening cores while keeping locks here....
  protected void clearMaps(ConfigSolr cfg) {
{code}

And then below it clears cores and transient cores (both vars shared across threads) without
a lock. This is the type of thing that will need to be fixed if we are to get rid of those
fails in the stress test is my guess.

> sub-task for SOLR-4083. If we're going to try to obsolete solr.xml, we need to pull all
of the specific XML processing out of Config and Container. Currently, we refer to xpaths
all over the place. This JIRA is about providing a thunking layer to isolate the XML-esque
nature of solr.xml and allow a simple properties file to be used instead which will lead,
eventually, to solr.xml going away.
