示例1: updateReplicationGraphForPromotedSlave

func (ta *TabletActor) updateReplicationGraphForPromotedSlave(tablet *topo.TabletInfo, actionNode *ActionNode) error {
	// Remove tablet from the replication graph if this is not already the master.
	if tablet.Parent.Uid != topo.NO_TABLET {
		err := ta.ts.DeleteReplicationPath(tablet.Keyspace, tablet.Shard, tablet.ReplicationPath())
		if err != nil && err != topo.ErrNoNode {
			return err
		}
	}
	// Update tablet regardless - trend towards consistency.
	tablet.State = topo.STATE_READ_WRITE
	tablet.Type = topo.TYPE_MASTER
	tablet.Parent.Cell = ""
	tablet.Parent.Uid = topo.NO_TABLET
	err := topo.UpdateTablet(ta.ts, tablet)
	if err != nil {
		return err
	}
	// NOTE(msolomon) A serving graph update is required, but in order for the
	// shard to be consistent the master must be scrapped first. That is
	// externally coordinated by the wrangler reparent action.

	// Insert the new tablet location in the replication graph now that
	// we've updated the tablet.
	err = ta.ts.CreateReplicationPath(tablet.Keyspace, tablet.Shard, tablet.ReplicationPath())
	if err != nil && err != topo.ErrNodeExists {
		return err
	}

	return nil
}
