Job

public class HandleFloodfillDatabaseLookupMessageJob
extends HandleDatabaseLookupMessageJob

Processes database lookup messages received by floodfill routers.

Handles incoming DatabaseLookupMessage requests from remote peers, performing database searches and sending appropriate replies. Extends the base lookup handling with floodfill-specific logic including query acceptance criteria and capability-based response behavior.

Determines whether to answer all queries based on floodfill status and capability flags. When not operating as floodfill, includes the local RouterInfo in responses to inform peers of the capability change and reduce misdirected queries.

Method Detail

answerAllQueries

protected boolean answerAllQueries()

Overrides:

answerAllQueries in class HandleDatabaseLookupMessageJob

Returns:

are we floodfill We don't really answer all queries if this is true, since floodfills don't have the whole keyspace any more, see ../HTLMJ for discussion

sendClosest

protected void sendClosest(Hash key,
                           Set<Hash> routerInfoSet,
                           Hash toPeer,
                           TunnelId replyTunnel)

We extend this here to send our routerInfo back as well, if we are not floodfill. This gets the word out to routers that we are no longer floodfill, so they will stop bugging us.

Overrides:

sendClosest in class HandleDatabaseLookupMessageJob
