* 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`
* Change History content key to us SSZ Union and adjust tests
* Change slot to byteBE instead of LE
This is currently not specified in the Portal network
specifications, but we are using already BE for the actual content
key, so change it also here to remain consistent.
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
* Add a basic ContentDB for Portal networks
* Use ContentDB in StateNetwork
* Avoid probably some form of sandwich problem by re-exporting kvstore_sqlite3 from content_db
* Allow for passing Portal specific bootstrap nodes
* Fix to also replaceNode when decodeMessage fails
* Add portal bootstrap node tests and reorder test cases
The Portal Network tests fail with the custom functions,
on one part due to the fact that the portal tests still
uses the xor functions, but also because the
`neighboursAtDistances` call appears to filter them out.
The reverse calculation might be off.
* Generalize netork layer for portal
* Make messages free from any content references
* Use portal network in main fluffy module
* Fix cli
* Use lookup in portal network
* Avoid using result
