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

Gustavo Santos Ferreira	605d28cb4d	preload token in queries that need it	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

Sebastian Abondano	a372acaa1d	Add contract#getabi API endpoint Why: * For API users to be able to get the ABI for a given contract address. 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. Documentation data lives in `BlockScoutWeb.Etherscan`	6 years ago

Lucas Narciso	46998b5afb	Create query to count transfers This query needs a token and an address, and will return how many times that address has interacted with that token. Also, fix some minor indentation issues and typos on chain_test.	6 years ago
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	152b2246ab	Add account#tokenbalance API endpoint Why: * For API users to be able to fetch the token balance for given contract and address hash. Example usage: ``` /api?module=account&action=tokenbalance&contractaddress={contractAddressHash}&address={addressHash} ``` * Issue link: https://github.com/poanetwork/blockscout/issues/571 This change addresses the need by: * Creating `Explorer.Etherscan.get_token_balance/2` to fetch the latest token balance for a given contract address and address hash. * Creating `API.RPC.AddressController.tokenbalance/2` action to process requests to `account#tokenbalance` API endpoint. * Editing `API.RPC.AddressView` to render token balances as needed. * Adding documentation data for the new API endpoint mentioned above. Documentation data lives in `BlockScoutWeb.Etherscan`.	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
Sebastian Abondano	0b42ed19f4	Add account#getminedblocks API endpoint Why: * For API users to be able to get a list of blocks mined by a given address. Example usage: ``` /api?module=account&action=getminedblocks&address={addressHash} ``` * Issue link: https://github.com/poanetwork/blockscout/issues/138 This change addresses the need by: * Adding `list_blocks/2` to `Explorer.Etherscan` to be get blocks as required by the new API endpoint added in this commit. * Adding `getminedblocks/2` action to `API.RPC.AddressController` to handle `account#getminedblocks` API requests. * Editing API.RPC.AddressView to render blocks as needed. * Adding docs for `account#getminedblocks` API endpoint. API docs live in `BlockScoutWeb.Etherscan`	6 years ago

Luke Imhoff	7eeb3226e2	Correct uniqueness of token balances Token balances, unlike balances, use 3 fields for uniqueness because 1 address can have a separate value for EACH token_contract_address_hash at EACH block_number.	6 years ago
Sebastian Abondano	1867d16417	Add account#tokentx API endpoint Why: * For API users to be able to get a list of token transfer events by address. A contract address can also be given, in addition to an address. Optional params include: 'startblock', 'endblock', 'sort', 'page', and 'offset'. Example usage: ``` /api?module=account&action=tokentx&address={addressHash} ``` * Issue link: https://github.com/poanetwork/blockscout/issues/571 This change addresses the need by: * Adding `Explorer.Etherscan.list_token_transfers/3` to get token transfer data required from db. * Adding `tokentx/2` action to `API.RPC.AddressController` to handle `?module=account&action=tokentx&...` API requests. * Editing `API.RPC.AddressView` to render token transfer events as needed. * Deleting duplicate line in `Explorer.Chain.TokenTransfer`. This looks like a typo. * Other than adding tests for the new functions mentioned above, `optional_params/1` within `API.RPC.AddressController` was promoted to a public function and unit tests were added for it. * Adding docs for `account#tokentx` API endpoint. Documentation data lives in `BlockScoutWeb.Etherscan`.	6 years ago

Sebastian Abondano	493695c95a	Add API txlistinternal action for account module Why: * For users to be able to get a list of internal transactions for a given transaction hash (Etherscan-compatible). * Issue link: https://github.com/poanetwork/blockscout/issues/138 This change addresses the need by: * Adding `Explorer.Etherscan.list_internal_transactions/1` to fetch internal transactions data as needed to be Etherscan-compatible. * Adding `txlistinternal/2` action to `API.RPC.AddressController` * Adding `txlistinternal.json` `render/2` function head to `API.RPC.AddressView` to render internal transaction lists as needed. * Adding documentation for the new action. Documentation data lives in `BlockScoutWeb.Etherscan` * Making `where_transaction_has_multiple_internal_transactions/1` a public function and adding doc, spec, and two new tests for it. This was necessary to use it from `Explorer.Etherscan.list_internal_transactions/1`.	6 years ago
