[jboss-jira] [JBoss JIRA] Commented: (JGRP-700) FLUSH: flushing should span merge

FLUSH: flushing should span merge --------------------------------- Key: JGRP-700 URL: http://jira.jboss.com/jira/browse/JGRP-700 Project: JGroups Issue Type: Task Reporter: Bela Ban Assigned To: Vladimir Blagojevic Fix For: 2.7, 2.6.3 When we run flush during a merge (say between {A,B} and {C,D}), then the flush protocol is run only when installing the new merge view {A,B,C,D} in both subgroups *individually*, e.g. flush is run for {A,B} and for {C,D}. If the flush in {C,D} completes sooner than the one in {A,B}, C and D will be able to send messages during {A,B}'s flush phase, thus violating the properties of flush. The change should be as follows: - A merge between the 2 subgroups is detected - If flush is enabled, run the flush protocol in {A,B} and {C,D}, *before* the new view V2={A,B,C,D} is installed - Install V2 - When the view installation is complete, ie. A and C have acked it, only *then* complete the flush and allow members to resume message sending
