Sebastian Abondano	1cbaafd894	Adds log rotation ... Why: * To limit the total size of the logs retained while still allowing analysis of recent events. * Issue link: n/a This change addresses the need by: * Editing the logger backends to do file rotation every 50mb and keep the last 19 log files per logger backend. 50mb * 20 = ~1gb	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	32535bd73c	Simplify WebSocketClient.respond_to_registration ... All clauses set request_id_to_registration in state to new_request_id_to_registration, so it does not need to be passed. The catchall cause does the equivalent because new_request_id_to_registration was request_id_to_registration already as Map.pop popped nothing.	6 years ago

Nam Chu Hoai	d17917ce30	Allow unsecure WebSocket connections ... Some setup like ours will have the WebSocket connection in a private network to a local node and thus do not require a secure connection. This change allows to specify ws:// instead of wss:// endpoints as well as reading from the ENV var for the geth config of the indexer Co-authored-by: Luke Imhoff <luke.imhoff@dockyard.com>	6 years ago

Lokraan	92f99cac22	Ran mix format on code. ... Confirm to CircleCi tests. Was failing due to not updating gettext, javascript lint standards, and an accidental edit in `block_controller.ex` where I added `:block => :required` to `necessity_by_association`. I also updated the query in `Explorer.Chain.address_to_validation_count/1` in order to make it more functional (use built in Ecto queries instead of hand written SQL query.) Conform to code review comments. Instances of "Blocks #{gettext("Validated")}" -> gettext("Blocks Validated") The class for the validation link in the mobile menus was "nav-link" instead of "dropdown-item" so I changed it. Ran `mix gettext.extract --merge` in order to update the gettext("Blocks Validated") Conform to code review. Added `active` classes to the corresponding links on mobile navs. Removed redundant if statements when in the page that required the content. Created a function in `address_view.ex` called `validator?` that accepts the number of validations and returns true if greater than 0. Replaced `if @validation_count > 0` with `if validator?(@validation_count`. "Please add the active class to the dropdown item." Added the `active` class where the page was active on for mobile and desktop navs. Also replaced `nav-item` with `dropdown-item` on the mobile navs where it was necessary.	6 years ago
Luke Imhoff	2f7be3fb7d	OTP application descriptions ... The Application selector in Wobserver shows the descriptions, so it is useful to be set.	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	ded4ec4246	Disable tests for Geth that timeout on Infura ... Infura experiencing timeouts with 50 second timeout set.	6 years ago
Luke Imhoff	b7d7ceaaa0	Temporary work-around for #673 value-only transactions ... The gas_used == gas heuristic means failures pre-Byzantium (and on ETC) is only a heuristic: it fails for value-only transactions where ETC submitters are using exactly the transaction base fee (21,000 gas) often. Because this is so common, we'll use this work-around now until we can restructure EthereumJSONRPC and Indexer to verify pre-Byzantium status using Internal Transactions.	6 years ago
