This commit updates geth to 1.8.17 and adds a possibility to enable metrics during compilation time.
The cascade of issues forced us to upgrade geth to 1.8.17 in order to allow enabling metrics during compilation time. 1.8.17 introduced `NodeID` refactoring and `enode` package which affected our peers pool and integration with Discovery V5.
- Replace command line flags with `-c` config flag. Part of #1180
- Convert node config private keys to hex-encoded string versions.
- Remove `GenerateConfig` from library.
- Remove unused `FirebaseConfig` from library.
- Fix loading of `config/status-chain-genesis.json` in non-dev machines.
In the current codebase if you want to use different keys (or any
other configuration) for tests it is required to place them at a
certain path in static folder, bundle them with go-bindata and only
then run tests. This is simply unnecessary.
This commit instead directs loads configurations from file without
relying on go-bindata
- Replace deprecated common.Hex with hexutil.Encode.
- Remove upstreamed 0010-geth-17-fix-npe-in-filter-system.patch.
- Remove upstreamed 0020-discv5-metrics.patch.
- Remove upstreamed 0026-ethdb-error-deadlock.patch.
- Update goleveldb to same version used by geth 1.8.11.
- Update PublicTransactionPoolAPI.GasPrice return type to match type in internal geth interface.
This change makes invalidation mechanism more aggressive. With a primary goal to invalidate short living nodes faster. In current setup any node that became known in terms of discovery will stay in this state until it will fail to respond to 5 queries. Removing them earlier from a table allows to reduce latency for finding required nodes.
The second change, one adds a version for discovery, separates status dht from ethereum dht.
After we rolled out discovery it became obvious that our boot nodes became spammed with irrelevant nodes. And this made discovery process very long, for example with separate dht discovery takes ~2s, with mutual dht - it can take 1m-10m and there is still no guarantee to find a max amount of peers, cause status nodes is a very small part of whole ethereum infra.
In my understanding, we don't need to be a part of ethereum dht, and lower latency is way more important for us.
Closes: #941
Partially closes: #960 (960 requires futher investigations on devices)
