[jboss-jira] [JBoss JIRA] Created: (JGRP-491) Multiplexer should execute getState for all registered MuxChannel under one FLUSH phase

Multiplexer should execute getState for all registered MuxChannel under one FLUSH phase --------------------------------------------------------------------------------------- Key: JGRP-491 URL: http://jira.jboss.com/jira/browse/JGRP-491 Project: JGroups Issue Type: Bug Affects Versions: 2.4.1, 2.5 Reporter: Vladimir Blagojevic Assigned To: Vladimir Blagojevic Fix For: 2.6 The idea behind MuxChannel state transfer listeners is to trigger all state transfers together and have all or none result for all registered MuxChannels. As currently implemented underlying plumbing with will trigger each transfer under *separate* FLUSH. In order to have it done under one flush we have to do manual flushing in Multiplexer (startFlush/stopFlush) for these transfers T and we should retrofit FLUSH protocol *not to* trigger flushing for each GET_STATE from T. We have two options: a) add requireFlush field in StateTransferInfo - that is then passed down with GET_STATE - this requires changing signature of JChannel.getState b) retrofit FLUSH to detect special handling of GET_STATE - at state requester A we record that we requested GET_STATE and if another GET_STATE arrives from A while channel is already flushed do not trigger another flush -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
