DHT Discovery #27

Open bltavares opened 3 years ago

bltavares commented 3 years ago

Use https://github.com/mattsse/hyperswarm-dht to find peers and exchange data over hyperswarm DHT.

TODO:

[x] Create DHTDiscovery that implements a stream of sockets
[x] Create Locator that finds new peers
[x] Create Announcer that announces it's feeds
[x] Integrate with hyperstack
[x] Figure out why lookup is returning empty and bootstrap takes so long to finish - https://github.com/mattsse/hyperswarm-dht/issues/5
[x] Fix TODOs related to DHT config/port/timeout
[x] Fix clippy/warnings

Closes #17

If we can troubleshoot why https://github.com/mattsse/hyperswarm-dht/issues/5 keeps returning peers = [] we can move forward with DHT support.

I'm not sure why it's happening - the DHT flow has not been easy to troubleshoot for me as I don't know much about the kademlia protocol.

Local tests with some patches on upstream dht implementation had progress!
