* Improvements to the propagation and seeding of data
- Use a lookup for nodes selection in neighborhoodGossip
- Rework populate db code and add `propagateBlockHistoryDb` call
and portal_history__propagateBlock json-rpc call
- Small adjustment to blockwalk
* Avoid storing out-of-range data in the propagate db calls
Currently re-using http connections for the json-rpc requests
seems to slow down the requests considerably. Avoid this by
forcing a close after each requests in the blockwalk tool.
* Sharing block header data around in a Portal history network (PoC)
- Rework PortalStream to have an instance per PortalProtocol (this
needs to be improved eventually). Each instance uses the same
UtpDiscv5Protocol instance.
- Add processContent on receival of accepted data
- Add dumb neighborhoodGossip: dumb in the sense that it only
offers one piece of content at a time.
- Add to / adjust populate_db to also allow for propagation of
the data and add debug rpc call: portal_history_propagate
- Add eth_rpc_client
- Add eth_getBlockbyHash (no txs or uncles) to eth API
- Add additional test to test_portal_testnet which loads 5 block
headers to 1 node, and offers this data to few nodes, which should
propagate it over the network further. Next query every node for
this data.
* Adjust paths on which Fluffy CI is triggered
* Add documentation on the local testnet
- Allow access to contentDB from portal wire protocol
- Use this to do the db.get in `handleFindContent` directly
- Use this to check the `contentKeys` list in `handleOffer`
- Add portal network ping and findNodes JSON-RPC endpoints
- clean-up of some cli arguments
- Add protocol_interop.md document and adjust/fix other
documentation
Currently bootstrap nodes for discv5 and for the Portal nodes
were provided through separate cli arguments. This is however
confusing and cumbersome as typically when (currently) testing
a node will have both discv5 and the Portal networks enabled.
We merge them into one argument.
If a node happens not to support a Portal network, it will be
removed after message request failure.
Commit also contains additional clean-up and nim-eth bump.
* Rename FindNode to FindNodes as per spec
* Use consistently lower case starting camelCase for consts
Style guide nep1 allows for both CamelCase and camelCase for
consts, but we seem to use more often camelCase. Using this now
consistently.
* Change some procs to func
* Add SSZ Unions through case objects
* Add connection id content response test and improve other test vectors
* Implement content keys and ids for state network as per spec
Content keys case object is used so that it can be serialized and
deserialized as an SSZ Union.
* Let message Union in Portal wire protocol start at 0 as per new spec
