Bolt 7 says in Rebroadcasting
We already had the function
request_gossip()
which was never called, so we only pulled the gossip by requesting channel ids inquery_gossip()
but never told the peer to forward gossip to us (by sendinggossip_timestamp_filter
).With this PR we also first check if the peer supports gossip queries (has
gossip_queries
feature bit) and limit the gossip fetching a bit by not requesting the full gossip every time we connect.
