In the previous version of cpg.c, we collected downlist info by interchanging messages among all nodes in the cluster. In my opinion, this is not necessary. We can calculate this info according left_nodes(my_member_nodes-trans_nodes) and its relative process_infos. So I discard message interchanging and collect downlist info directly in cpg_leftlist_collect function. Although I calculate downlist information directly in local, but Iwon't send it until I have collected all joinlist as regular messagesamong all nodes in the cluster. Even if there are no one joinlistcontent among all nodes, this patch will also send _bare_ joinlistincluding only the message header so that all nodes can receive alljoinlist message and reach synchronization finally. So I think itwon't deliver configuration changes to the application ahead of theregular messages. I known that merging downlist and joinlist into one confchg event willbreak wire compatibility, but I think it will be more reasonable, andmost important it reflect the truth and obey the CPG API description. -- Yunkai Zhang Work at Taobao _______________________________________________ discuss mailing list discuss@xxxxxxxxxxxx http://lists.corosync.org/mailman/listinfo/discuss
