[mod_cluster-issues] [JBoss JIRA] Commented: (MODCLUSTER-220) Extra REMOVE-APP event after failover

Extra REMOVE-APP event after failover ------------------------------------- Key: MODCLUSTER-220 URL: https://issues.jboss.org/browse/MODCLUSTER-220 Project: mod_cluster Issue Type: Enhancement Reporter: Radoslav Husar Assignee: Jean-Frederic Clere Priority: Trivial Trivial thing: I think there is an extra REMOVE-APP event happening after fail-over. The test scenario is simple - start a node with 6 context, kill the node and reconnect. The apps are unchanged but 5 are remembered as were and one is removed and added back? Since they happen at the same time it looks like it happens uselessly and can cause race condition. {code} 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "INFO / HTTP/1.0" 200 - "-" "ClusterListener/1.0" 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "CONFIG / HTTP/1.0" 200 - "-" "ClusterListener/1.0" 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "ENABLE-APP / HTTP/1.0" 200 - "-" "ClusterListener/1.0" 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "ENABLE-APP / HTTP/1.0" 200 - "-" "ClusterListener/1.0" 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "ENABLE-APP / HTTP/1.0" 200 - "-" "ClusterListener/1.0" 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "ENABLE-APP / HTTP/1.0" 200 - "-" "ClusterListener/1.0" 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "ENABLE-APP / HTTP/1.0" 200 - "-" "ClusterListener/1.0" 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "ENABLE-APP / HTTP/1.0" 200 - "-" "ClusterListener/1.0" 127.0.0.1 - - [04/Apr/2011:19:18:34 +0200] "STATUS / HTTP/1.0" 200 58 "-" "ClusterListener/1.0" ... 127.0.0.1 - - [04/Apr/2011:19:19:03 +0200] "GET /SessionTest/SessionTestServlet?
