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	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

Luke Imhoff	d42fbdb06e	Treat "status" => nil the same as no status ... While Geth does not return a status for pre-Byzantium blocks, Parity returns `"status" => nil`, so treat `"status" => nil` as if `"status"` wasn't there.	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	9a8cdc4031	Use Path.absname so that log paths are stable during reload ... Fixes #628 The Phoenix.CodeReloader causes the file loggers to restart and reload their config, but when they reload, the current working directory has shifted from the project root to the OTP app root, so it produces log files under each OTP app (`apps/APP_NAME/logs`). We don't want this, so compute the absolute path in the config files, so that the loaded `Application` environment has an absolute path in it that can't shift when the working directory changes.	6 years ago

Luke Imhoff	f32d6d43dd	Use curl to signal parallel build is done to coveralls.io ... Using `curl` in a job instead of the `notify` `webhook` allows us to interpolate the COVERALLS_REPO_TOKEN instead of disclosing it in the config.yml. Use KronicDeth/excoveralls@circle-workflows because upstream hex.pm excoveralls does not properly support parallel jobs run in separate Workflow jobs.	6 years ago
Luke Imhoff	fdd1090c45	Re-enable Ecto loggers ... Allow Ecto loggers to log to the application-specific log **file**, `log/<Mix.env>/ecto.log` but raise `:console`'s level to `:info`, so that Ecto output does not flood `iex` and make it unusable.	6 years ago
Luke Imhoff	c032ea2291	Improved logging ... Have separate loggers for errors and per-application. * `:console` will continue to have all applications and levels. Level is - `:debug` for `dev` - `:warn` for `test` - `:info` for `prod` * `:error` is only for errors across all environments. It uses `LoggerFileBackend` and writes to `logs/<Mix.env>/error.log`. * `:block_scout_web` is only when `:application` metadata is `:block_scout_web`. Level is - `:debug` for `dev` - `:warn` for `test` - `:info` for `prod` It uses `LoggerFileBackend` and writes to `logs/<Mix.env>/block_scout_web.log`. * `:ethereum_jsonrpc` is only when `:application` metadata is `:ethereum_jsonrpc`. Level is - `:debug` for `dev` - `:warn` for `test` - `:info` for `prod` It uses `LoggerFileBackend` and writes to `logs/<Mix.env>/ethereum_jsonrpc.log`. * `:explorer` is only when `:application` metadata is `:exploer`. Level is - `:debug` for `dev` - `:warn` for `test` - `:info` for `prod` It uses `LoggerFileBackend` and writes to `logs/<Mix.env>/explorer.log`. * `:indexer` is only when `:application` metadata is `:indexer`. Level is - `:debug` for `dev` - `:warn` for `test` - `:info` for `prod` It uses `LoggerFileBackend` and writes to `logs/<Mix.env>/indexer.log`.	6 years ago
Luke Imhoff	9a4a23b5c5	Remove EthereumJSONRPC.WebSocket impl that don't work with Infura ... Don't rebase them out, so that we have the history that we tried to use `socket` and `websockex`, but we couldn't get them to work.	6 years ago

Luke Imhoff	cddd810a58	Use :websocket_client for EthereumJSONRPC.WebSocket ... :websocket_client can properly use :ssl_verify_hostname.verify_fun/3 for :verify_fun and allow for the handshake to both be secure and pass for infura.	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

Luke Imhoff	f2884992a7	Fetch realtime internal transactions and balances synchronously ... Fixes #366 Queuing the internal transactions and balances to be fetched asynchronously for realtime blocks lead to upto 15 minute delay between when a block appeared and the internal transaction was drained from the queue. It is a better user experience to not see the realtime blocks at all than to see them incomplete, so fetch the internal transactions and then the balances before importing the whole tree of data instead of using the catchup asynchronous queues.	6 years ago

Lucas Narciso	537f090597	Create Explorer.SmartContract.Reader ... This new module is the main entry point for getting results of a smart contract function. It accepts a smart contract hash and a list of functions names and its arguments (when applicable) in order to execute those functions and return their results. Before actually making the call to the blockchain, the function name is encrypted and the arguments are encoded. The EthereumJSONRPC deals with this, encrypting the name of the function using the Keccak256 algorithm and encoding the arguments based on their type. The call to the blockchain is also made by EthereumJSONRPC. The result is then decoded - as it comes in the same type of encoding that has been sent - by the EthereumJSONRPC lib as well, and returned. The return is a list of results of calling the functions in the blockchain. Note that each function may return more than one result, so for each functions there is a list of results.	6 years ago
Lucas Narciso	4b9bc4a69f	Create EthereumJSONRPC.Encoder ... It deals with encoding and decoding data to be sent to, or that is received from, the blockchain.	6 years ago
Lucas Narciso	8a8f2bb20b	Add the ABI lib to handle encoding and decoding ... This lib makes it easy to handle multiple types of arguments and it also deals with all the Keccak256 cryptography. The need to handle multiple types of arguments comes from the Ethereum Virtual Machine, that expects those values in a particular way. Also, the functions' names should also be written in a particular way using the Keccak256 algorithm.	6 years ago
Lucas Narciso	e81281edf6	Fix typo in etheream_jsonrpc_test.exs ... Rename it to ethereum_jsonrpc_test.exs	6 years ago
Lucas Narciso	acdbed2ba7	Support eth_call on EthereumJSONRPC ... It just makes the call, so the smart contract function name should already be encrypted and its arguments already encoded. It supports multiple function calls, by receiving a list of hashs and data, e.g. `[{contract_hash_1, call_data_1}, {contract_hash_2, call_data_2}]`.	6 years ago
Luke Imhoff	ac841af29f	Split batches on 504 Gateway Timeout ... Under the assumption that gateway timeouts occur because it is taking too long for Sokol nodes to respond to batch requests, 504 Gateway Timeout should be treated the same as 413 Request Entity Too Large: the batch should be split in half and retried. If we still get 504 Gateway Timeouts after this change, we'll need to add a delay before retry.	6 years ago
Luke Imhoff	8f827ecfa6	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.	6 years ago
Luke Imhoff	834ad23f26	Standardize JSONRPC response ... Restrict response to only those fields supported by the JSON-RPC 2.0 standard, which means that level of keys is validated, so we can indicate that switch to atom keys.	6 years ago
