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

Lucas Narciso	428e674667	Handle more errors types at Smart Contract Reader Errors may pop up that do not comply with the current expect API: they may not include a :message key in its formation. When they did not, the exception handler was throwing an exception.	6 years ago

Felipe Renan	e4d4154fc7	Build query to fetch transactions with token transfers The query is scoped by the given address hash and the token hash. So, it will considers transactions that have token transfers so that the given address hash is the `to` or the `from` from a token transfer.	6 years ago

Sebastian Abondano	36d3d95e68	Improve transaction#getstatus API endpoint Why: * To increase the accuracy of `transaction#getstatus` API endpoint results. * Issue link: https://github.com/poanetwork/blockscout/issues/743 This change addresses the need by: * Editing `transaction#getstatus` API endpoint to use the recently added `Chain.transaction_to_status/1` function. This improves the accuracy of the errors by providing a reason of `awaiting internal transactions` for transactions with a failed status but for which the final "real" error message will only become available after processing the internal transactions. * Deleting `Explorer.Etherscan.get_transaction_error/1`. It's no longer needed.	6 years ago
Sebastian Abondano	6be5bc81b7	Derive status from internal transaction at index 0 Why: * Issue #757 was created after we noticed a few constraint violations for the `error` column in the `transactions` table. The constraint violations came about as we attempted to update transactions with a successful status but some value for the error field. The constraint is violated in this scenario because we expect successful transactions to not have an error. [EIP 658](https://github.com/ethereum/EIPs/pull/658), which apparently is also called [EIP 98](https://github.com/ethereum/EIPs/issues/98#issuecomment-318670322) , says that the status should be set to 1 (success) if the outermost code execution succeeded (internal transaction with index 0), or it should be set to 0 (failure) if the outermost code execution failed. We're currently deriving the status from the last internal transaction when in fact we should be deriving it from the first internal transaction. * Issue link: https://github.com/poanetwork/blockscout/issues/757 This change addresses the need by: * Editing `Explorer.Chain.Import.update_transactions/2` to set the error for a transaction equal to the error, if any, of the internal transaction with index 0. * Editing `Explorer.Chain.Import.update_transactions/2` to set a transaction's status as successful if it's internal transaction at index 0 doesn't have an error, and as failed if it does. This only applies to pre-Byzantium and Ethereum Classic, for which transaction status is not set from receipts.	6 years ago

Luke Imhoff	102f467948	Denormalize last internal transaction error to transaction Allow UI and APIs to get the overall transaction error easily when status is `:error` without have to preload all the internal transactions.	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

Felipe Renan	53cb6de504	Handle multiple values when reading Smart Contract functions We received the following error when a function executed by the contract returned multiple values: ``` an exception was raised: ** (FunctionClauseError) no function clause matching in Explorer.SmartContract.Reader.new_value (explorer) lib/explorer/smart_contract/reader.ex:272: Explorer.SmartContract.Reader.new_value( %{"name" => "narcoName", "type" => "string"}, ["Justin Sun", 0, 0, [8, 6, 9, 2, 2, 37], [0, 0, 0, 0], "m0310100904381635021206170608010621080706", 6, 33, [1533368345, 1533331805, 1533339540, 1533333875, 0, 0], 277, [72, 29, 59, 0, 1, 0, 2, 73, 0] ] ) (explorer) lib/explorer/smart_contract/reader.ex:268: anonymous fn/3 in Explorer.SmartContract.Reader.link_outputs_and_values/3 ``` As the returned values match with the ABI outputs, we are relying on output's index to fetch the correct value for each output. This commit also fixes the template to deal with different results, such as: `[8, 6, 9, 2, 2, 37]`, that is an array of numbers but the Phoenix view considers it as a char-list.	6 years ago
Sebastian Abondano	ed66f9f87e	Orders account#getminedblocks by block number Why: * To match Etherscan's API we want to ensure blocks returned by the `account#getminedblocks` API endpoint are ordered by descending block number. We noticed this wasn't the case when looking into a couple of flaky tests on CI. This commit should also make sure the tests don't randomly fail any more. These are the two tests: - test/block_scout_web/controllers/api/rpc/address_controller_test.exs:1674 - test/explorer/etherscan_test.exs:1014 * Issue link: n/a This change addresses the need by: * Editing `Explorer.Etherscan.list_blocks/1` to order blocks by descending block number. * Related tests were edited according to the change above.	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
Felipe Renan	d9ff36c00d	Fix token balances' query This query was considering the next-to-last token balance when the last one had the value 0. In order to this work properly, I'm moving the query that gets token balances from the last block to a sub-query and moving the condition to consider just values greater than 0 to the main query. This way we are sure that we always are considering the last block and we are skipping the ones that have the value equal to 0.	6 years ago

Example usage: ``` /api?module=contract&action=getabi&address={addressHash} ``` * Issue link: https://github.com/poanetwork/blockscout/issues/138 This change addresses the need by: * Editing router to support `contract#getabi` API endpoint. * Creating `API.RPC.ContractController.getabi/2` action to process requests to `contract#getabi` endpoint. * Creating `API.RPC.ContractView` to render `contract#getabi` responses. * Adding documentation data for the new `contract#getabi` API endpoint.

Sebastian Abondano	a07998547f	API account#txlist filterby=from support Why: * For API users to be able to get a list of transactions in which a given address is the 'sender' (address is the 'from' in transaction). Example usage: ``` /api?module=account&action&txlist&address={someAddress}&filterby=from ``` * Issue link: https://github.com/poanetwork/blockscout/issues/635 This change addresses the need by: * Editing `where_address_match/3` in `Explorer.Etherscan` to support `filter_by: "from"` option. * Editing `put_filter_by/2` in `API.RPC.AddressController` to support 'from' as an allowed value of the `filterby` parameter. * Editing API docs page per changes mentioned above.	6 years ago

Sebastian Abondano	24e5da232f	Add filterby flag to account#txlist Why: * For API users to get a list of transactions in which the given address is the 'to' in the transaction. Example usage: ``` /api?module=account&action&txlist&address={someAddress}&filterby=to ``` * Issue link: https://github.com/poanetwork/blockscout/issues/138 This change addresses the need by: * Editing `API.RPC.AddressController`'s `txlist/2` action to support a `filterby` flag in which the only allowed value for now is `to`. This is an optional parameter. When given this filters the returned transactions to only those in which the given address matches the `to` field. When not given, the address provided could match the to, from, or contract address for the transaction. * Editing `Explorer.Etherscan`'s `list_transactions/3` to support the new `filterby` flag mentioned above. * Editing API docs data in `BlockScoutWeb.Etherscan` to include information about the new `filterby` flag added in this commit.	6 years ago
