[jboss-jira] [JBoss JIRA] Commented: (JGRP-618) FLUSH coordinator transfer reorders block/unblock/view events in applications (TCP stack only)

FLUSH coordinator transfer reorders block/unblock/view events in applications (TCP stack only) ---------------------------------------------------------------------------------------------- Key: JGRP-618 URL: http://jira.jboss.com/jira/browse/JGRP-618 Project: JGroups Issue Type: Bug Affects Versions: 2.6 Reporter: Vladimir Blagojevic Assigned To: Vladimir Blagojevic Fix For: 2.6 When flush coordinator A runs a flush for a view that excludes himself a flush coordinator transfer occurs. Member B that is first next neighbor of A according to view has to complete the flush by sending STOP_FLUSH to all. Simplification of FLUSH JGRP-598 removed complex stop flush phase. In new design as soon as member receives STOP_FLUSH it unblocks application by sending UNBLOCK. Now, during coordinator transfer described above we first have to send a view up to application and then invoke STOP_FLUSH. If we do it other way around STOP_FLUSH will loop back and cause delivery of UNBLOCK to application prior to new view - thus causing reordering of block/unblock/view events in applications.
