[jboss-jira] [JBoss JIRA] Commented: (JGRP-859) Message: add LOOPBACK flag

[Bela Ban (JIRA)]

    [ https://jira.jboss.org/jira/browse/JGRP-859?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12437841#action_12437841 ] 

Bela Ban commented on JGRP-859:
-------------------------------

It's useless to only mark VIEW and SUSPECT messages as LOOPBACK, because, although this will cause suspicions to work and clusters to fall apart, messages sent *after* a network partition will still not be received by self because the NIC doesn't forward them.
Setting LOOPBACK to true by default in all messages would help, but then we might as well set TP.loopback to true by default (JGRP-155)...

> When LOOPBACK is set in a message, the UNICAST.loopback and TP.loopback flags are overridden and a message is looped back up the stack, regardless of the value of the property.
> This is useful for example for VIEW and SUSPECT messages, where a socket could be disconnected (e.g. cable plugged) and we still need to be able to receive our own messages.
