dht_node: add hasContacts method 
This method can be used by other components to check
if in the Node routing table there is at least one peer.

dht_node: split network start and join procedures 
In order to attempt to join the DHT several times
(i.e. when the first attempt has failed) we need to
split the components initialization from the real
joining operation.

Create node.startNetwork() to initialize the node
and keep the rest in node.joinNetwork()

Antonio Quartulli 965969b856 Don't filter out local node ID when returning peer list 
If a node is returning a peer list for a given blob hash
(being this been requested via CLI or via DHT) and it is
part of the resulting peer list, it will filter itself out
before returning the list.

This makes the results across the DHT inconsistent as
different nodes won't include themselves when
responding a findValue/findNode query.

Remove such filtering so that the local node ID is always
included when needed.

fix remaining length of close nodes list 2017-10-27 21:46:17 -04:00
Antonio Quartulli 673d1c4d43
Extend close nodes list by right amount 
When a k-bucket does not contain enough close nodes, the
DHT will look into neighbouring k-buckets in order to entend
the list of returned nodes.

However, the list should not be extended beyond its maximum size.
