Request transport module and options for all JSONRPC calls To lessen load on Sokol chain nodes during testing and to allow substituting different transports than HTTP, such as IPC, in the future, pass the transport module and its options to any call to `EthereumJSONRPC.json_rpc`. This will allow us to use a `mox` module in local testing, so we only do true chain integration testing in CircleCI.

ETHEREUM_JSONRPC_HTTP_TIMEOUT env variable
2 years ago
http_options: [recv_timeout: timeout, timeout: timeout, hackney: hackney_opts]
Use Mox by default for local integration tests How to run without Mox is in the root `README.md`. Run all combinations of Variant and Transport on CircleCI to ensure that Mox matches HTTP behavior, so Mox can be used for fast local testing: * Geth, HTTP * Geth, Mox * Parity, HTTP * Parity, Mox Using Mox locally also lessens load on Sokol and the Infura API key the tests use for Geth under the assumption that we do far more local testing than CI testing. May help with #340, but does not fix the root cause, which is now known as `Sequence` not chunking ranges correctly on retry.

Rename obsolete "parity" EthereumJSONRPC.Variant to "nethermind"
2 years ago
variant: EthereumJSONRPC.Nethermind
Subscribe to newHeads for realtime indexer Separate Catchup and Realtime indexer's fetching, so that Catchup continues to use the old polling, `EthereumJSONRPC.json_rpc` while Realtime subscribes with `EthereumJSONRPC.subscribe`. Because Realtime gets notified of new blocks through the subscription, it no longer has a Sequence, so Sequence has been removed from `%BlockFetcher{}`. There is also no block concurrency or block batch size for Realtime, so that was removed from `%BlockFetcher{}` too and moved to `%BlockFetcher.Catchup{}`. Because Realtime requires a websocket to be connected, there is now an `Indexer.BlockFetcher.Realtime.Supervisor` that supervises the `Indexer.BlockFetcher.Realtime.WebSocket` and `Indexer.BlockFetcher.Realtime`. `Indexer.BlockFetcher.Realtime` because it is waiting on notifications from is subscription becomes a `GenServer` insteado of a `Task`, so it can be supervised normally. BlockFetcher.Supervisor becomes a normal `Supervisor` of `Catchup.Supervisor` and `Realtime.Supervisor`. As Realtime is using `EthereumJSONRPC.subscribe`, `subscribe_named_arguments` has been added as a sibling of `json_rpc_named_arguments` in the `:indexer` `config`s.
