Luke Imhoff	3499155cdb	Partial retries for fetch_blocks_by_range ... Means that both Block.Fetchers, realtime and catchup, now handle fetch errors. The Block.Catchup.Fetcher will retry those blocks that failed to fetch while importing the rest that did fetch instead of refetching the whole batch.	6 years ago

Sebastian Abondano	345bec4a7a	fetch_beneficiaries/2 works with all reward types ... Why: * For the indexer to update block reward contract beneficiaries for all types (e.g. block, external, uncle, etc). For details on Parity's reward types please see: 0f90696528/rpc/src/v1/types/trace.rs (L299-L308) * Issue link: https://github.com/poanetwork/blockscout/issues/767	6 years ago
Luke Imhoff	e4b7a4ee5f	Geth internal transactions ... Get internal transactions using debug_traceTransaction and a custom tracer. The tracer was based on the callTracer that ships with Geth, but rewritten to break it into more functions with more explicit purpose and to patch some holes in callTracer: * All calls have gas and gasUsed, which patches the hole in callTracer for handling `DELEGATECALL`. * All calls have value, which patches the hole in callTracer for handling `DELEGATECALL` and `STATICALL`. Since the tracer needed to be resubmitted in whole anyway, it was further customized to match the format needed for internal transactions: * Instead of returning the `op` as `type`, the `type` and `callType` used for internal transactions is returned. * Instead of returning a call tree, the tree is walked in pre-order, displaying the parent call before its nested calls to match the flat order returned from parity's trace_transaction.	6 years ago

Sebastian Abondano	2b8ceb4e32	Update block reward contract beneficiary balances ... Why: * "Parity’s consensus engine allows using a smart contract for block reward calculation." - see https://wiki.parity.io/Block-Reward-Contract for details. This means that we need to use `trace_block` (https://wiki.parity.io/JSONRPC-trace-module#trace_block) to fetch the block reward contract beneficiaries and update their balances. Currently this doesn't happen so there are addresses (block contract reward beneficiaries) with inaccurate balances and missing rows in the `address_coin_balances` table. * Issue link: https://github.com/poanetwork/blockscout/issues/767 This change addresses the need by: * Adding `EthereumJSONRPC.fetch_beneficiaries/2` to help us fetch the block reward contract beneficiaries of a given block range. This only works with Parity. * Editing Indexer's dev and prod config by adding `trace_block` config to `:method_to_url`. * Adding `block_reward_contract_beneficiaries` to `Indexer.AddressExtraction` for it to know how to get addresses in this scenario. * Editing `Indexer.Block.Fetcher.fetch_and_import_range/2` to get block reward contract beneficiaries, create their addresses if they don't yet exist, and update their coin balances.	6 years ago
Luke Imhoff	1100f56fa1	Test WebSocketClient with cowboy_websocket_handler ... Allows to properly simulate TCP disconnect.	6 years ago
Luke Imhoff	b1f4696569	Reconnect, rerequest, and resubscribe when websocket disconnects ... * Use struct, `%EthereumJSONRPC.WebSocket.WebSocketClient.Options{}` to hold `web_socket_options`. * `%EthereumJSONRPC.WebSocket.Registration{}` * Record `t:EthereumJSONRPC.request/0` in `%EthereumJSONRPC.WebSocket.Registration{}`, so that the request can be re-requested if the websocket disconnects and reconnects. * Drop server-side `subscription_id` from `%EthereumJSONRPC.WebSocket.Registration{}` as it can retrieved from `request` now. * `EthereumJSONRPC.WebSocket.WebSocketClient` * Track whether the web socket is connected or not, so that requests aren't sent when in the disconnected state. This prevents double-sends as `handle_call` can be called before `onconnect`, which caused that first subscribe to be sent twice. * Instead of the subscriber knowing the server-side subscription id, an opaque `t:reference/0` is used, so that the reference is stable in the subscriber's `%Subscription{}`, but the subscription ID can change on reconnect, which means replacing `subscription_id_to_subscription` in `%WebSocketClient{}` with 3 maps 1. `subscription_id_to_subscription_reference` - used translate server-side, per-connection subscription to the stable reference in `subscription_reference_to_subscription` 2. `subscription_reference_to_subscription_id` - used to convert stable reference to subscription id to unsubscribe. 3. `subscription_reference_to_subscription` - used to get full Subscription, including the subscriber_pid for when subscription messages are delivered or the subscription needs to be resubscribed using the `web_socket_options`. * `ondisconnect`, `:reconnect` immediately. * When disconnecting, tell unsubscribers they were successful. * Hold any json_rpc or subscribe requests to retry on reconnect. * Hold any subscriptions to resubscribe on reconnect. * `onconnect` * re-request the saved json_rpc and subscribe requests. * issue new requests to re-establish the subscriptions that had already succeeded in their subscribe requests. * `%EthereumJSONRPC.Subscription{}` * Replace `id`, which did match the server created ID, with a `t:reference/0`, which allows for indirection and for the server created ID to change on reconnect while the subscriber does not need to care about the reconnections. * `EthereumJSONRPC.WebSocket` * `options` is switched from a Keyword.t to a struct, `t`, so that it is easier to pattern match for the reconnect logic in `WebSocketClient`. * `web_socket_options` is no longer a generic `term` because the code did require it to be a map with a `:web_socket` key for the `t:GenServer.server/0`.	6 years ago

Luke Imhoff	96d5aea311	Block.SecondDegreeRelation ... The database table block_second_degree_relations contains links between the `uncle_hash` of the uncle and the `nephew_hash` of the block that said `uncle_hash` was an uncle. It also has a `uncle_fetched_at` that is `null` until the `uncle_hash` is confirmed as fetched in the database. This does not contain such a fetcher.	6 years ago

Luke Imhoff	b32f263eda	Allow status to be nil until internal transactions are indexed ... For pre-Byzantium or Ethereum Classic (which never adopted EIP-658), the status in receipts will be `nil`, but we still want to ensure the status is eventually set, so when setting internal transactions, in addition to setting `internal_transactions_indexed_at` and `created_contract_address_hash`, the `status` will be updated. * If the `status` is already set, leave it as is * If the `status` is not set * If the last internal transaction for a transaction has an error, `status` is `:error` * If the last internal transaction for a transaction has no error, `status` is `:ok`	6 years ago
Luke Imhoff	baa5746a25	Don't infer status for gas and gas_used ... The heuristic of gas == gas_used is an error has been proven to be incorrect with test transactions on Ethereum Classic, so remove it. When the status is not given it will be propagated up as `nil` and must be filled in by the caller using the internal transactions.	6 years ago

Igor Florian	d460fb8d50	Deal with :bad_gateway errors while querying contracts functions ... We were counting on a specific error standard from ethereum_jsonrpc for formatting the errors from the SmartContract.Reader and we ended up getting an exception because we were getting a different error. There are at least two different error standards returned from ethereum_jsonrpc: 1. ```elixir { :ok, [ %{ id: id, jsonrpc: "2.0", error: %{ code: "12345", message: "<message>" } } ] } ``` 2. ```elixir {:error, {:bad_gateway, "<url>"}} ``` We're now expecting the :bad_gateway error so we can format it properly.	6 years ago

Luke Imhoff	854230f25f	Better error message when receipt cannot be converted to elixir ... Resolves #618 Use the validation pattern of reducing all entries while ok, but then switching to accumulating all errors once any error occurs. Finally, because the fields that identify the receipt precisely, such as the transactionHash or blockNumber may not have an error, include the full receipt the ArgumentError exception.	6 years ago

Luke Imhoff	c8c53405fc	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.	6 years ago
