[jboss-jira] [JBoss JIRA] Resolved: (JGRP-925) TCPPING: not all nodes have all physical addresses

TCPPING: not all nodes have all physical addresses -------------------------------------------------- Key: JGRP-925 URL: https://jira.jboss.org/jira/browse/JGRP-925 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.8 - We have A and B - TCPPING for A and B lists A and B as initial_hosts - C's config lists only A as initial_hosts - When C joins, it 'll ping only A, so it has information about A's physical address in its cache - Plus, the discovery response from A also adds information about A to C's cache - HOWEVER, C does not have the physical address of B, and B doesn't have the physical address of C ! --> When C multicasts a message, B will not receive it --> When B multicasts a message, C will not receive it The reason is that a discovery response from a node N only contains the logical-physical mapping for N, but not for other nodes. SOLUTION: introduce property return_entire_cache. By default, this is false, but TCPPING sets it to true. When A gets the discovery request from C, it'll return information about A *and* B. When B wants to send a multicast, it'll skip C though, but on the next MERGE2, it'll get the physical address of C. Retransmission will then make sure C receives B previously dropped multicast
