RpcDispatcher / MessageDispatcher: add exclusion list to compute target membership ---------------------------------------------------------------------------------- Key: JGRP-1192 URL: https://jira.jboss.org/jira/browse/JGRP-1192 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.10 [Email Paul Ferraro] Always send an address list PLUS a bit flag that indicates how to interpret the list. If the flag is 0, interpret the list as a target list. If the flag is 1, interpret the list as an exclusion list. When a target list is specified for an rpc, compare the size of the membership list with the target list. If (target * 2) <= membership, send list with exclusion flag = 0. If (target * 2) > membership, send set difference between membership and target list with exclusion flag = 1. On the receiving end, if exclusion flag is 0, handle the message if we're in the list of addresses; if exclusion flag is 1, handle the message if we're NOT in the list of addresses. A rpc with a null target list would always use a exclusion flag of 1, exclude nothing. Even better, add new RpcDispatcher/MessageDispatcher methods to invoke on all except a list of addresses. This way, jgroups doesn't need to do anything "clever" - but always send list + bit flag in accordance with API. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
