[jboss-jira] [JBoss JIRA] (JGRP-2409) Add more logging to MERGE3

Add more logging to MERGE3 -------------------------- Key: JGRP-2409 URL: https://issues.jboss.org/browse/JGRP-2409 Project: JGroups Issue Type: Enhancement Affects Versions: 4.1.8 Reporter: Olivier Peyrusse Assignee: Bela Ban Priority: Major Fix For: 4.1.9 MERGE3 comes with a good number of log traces. Combined with logs from TCP, TP, Merger and other protocols, it provides a good understanding of what is happening in the application. Yet, when it comes to the actual process of merge run by {{ViewConsistencyChecker#_run}}, we lack details about what happens before performing the merge. Particularly, we can track when VIEW_REQ messages are sent but we don't know what happen in the checker when responses are processed: - which views were received? - when are they received? - what is the final result on which the MERGE3 logic is executed - is the merge cancelled or aborted? In my [forked branch|https://github.com/OPeyrusse/JGroups/tree/add-loggin-to-merge3], I added 5 traces that helped me understand what was going on in my cluster. Tell me if it is the right way to suggest improvements. Regards
