Amanda Sposito	73856a72df	Add read only functions to 'SmartContract.Reader'	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

Sebastian Abondano	e8a9b63d7b	Add account transactions API RPC endpoint ... Why: * For users to be able to get the transactions for a given address hash. Support for optional parameters will be added in an upcoming PR. * Issue link: https://github.com/poanetwork/poa-explorer/issues/138 This change addresses the need by: * Adding `Explorer.Etherscan` context, where we want to keep etherscan-only logic within the Explorer app. This is because we want to mimic the way their RPC API works. The only function in this module for now is `list_transactions/1`, which gets all transactions for a given address hash. * Adding `txlist/2` action to `API.RPC.AddressController`, to handle account transactions requests. Example usage: ``` api?module=account&action=txlist \ &address=0xddbd2b932c763ba5b1b7ae3b362eac3e8d40121a ``` * Editing `API.RPC.AddressView` and `API.RPC.RPCView` to format responses for new API endpoint as required. * Editing `.credo.exs` to allow for `Hash.Address.t()` alias usage in `Explorer.Etherscan` without Credo complaining with: ``` Software Design ┃ ┃ [D] ↓ Nested modules could be aliased at the top of the invoking module. ┃ apps/explorer/lib/explorer/etherscan.ex:19:51 ```	6 years ago
Sebastian Abondano	cc059dac1e	Enhance API account balance endpoint ... Why: * Currently, the API account balance endpoint allows users to get the ether balance for a single address. This commit introduces support for getting the ether balance for multiple addresses (maximum of 20) in a single batch. * Issue link: https://github.com/poanetwork/poa-explorer/issues/138 This change addresses the need by: * Adding `Chain.hashes_to_addresses/1` to get multiple addresses from the DB, given a list of hashes. * Editing `balance/2` in `API.RPC.AddressController` to support multiple addresses. Previously it only supported a single address. * Editing `API.RPC.AddressView` to handle a single address differently than multiple addresses. This is to mimic Etherscan's API.	6 years ago
Felipe Renan	ceb971b285	Add contract creator on Account details page ... Now the user will be able to see the contract creator and the transaction references to it on the Account details page when the address is a contract. In order to this work we had to make a query that returns the internal transaction that has the contract creation. This way we can get the `from_address` that represents the contract creator and the transaction from the internal transaction.	6 years ago
Stamates	8efdf3e0e8	Sort internal_transactions oldest to newest on transaction page	6 years ago
Tim Mecklem	4da2959014	Exclude non-contract-creation parent transactions from contract page ... When a parent transaction executes a contract that creates other contracts, those contract address pages should not include the parent transaction in the transactions tab since it has non-matching from and to addresses.	6 years ago
Stamates	025ed91dcb	Fix multiple results in Repo.One with multiple create type internal transactions	6 years ago
Luke Imhoff	8b5327ad65	Remove public_key and standard_v from transactions ... public_key and standard_v is only exposed by Parity, so to allow for Geth compatibility, public_key and standard_v should be removed. If they are needed, they can be recovered from r, s, and v.	6 years ago
Luke Imhoff	53d34141ee	Convert blocks nonce to bytea ... A block nonce is an 8-byte hash. Only triggered for Ethereum Mainnet where nonce is used for Proof-of-Work. Nonce was unused and 0 for POA networks like Sokol.	6 years ago
Luke Imhoff	904a63b504	Explorer.Chain.Hash.Truncated -> Explorer.Chain.Hash.Address ... Blocks nonce will also be a type of hash, but it is only 8-bytes, instead of 20-bytes, so the general name "Truncated" will be confusing, so name it "Address" to be specific.	6 years ago

Igor Florian	bc3a0e71ea	Include all build versions in versions list ... We're now listing all existent solidity's version, even those that are unstable. Also, the "lastest" label was added so the user doesn't need to select any the last version.	7 years ago
Igor Florian	7798a72584	Load the previous compiler version when verification fails ... We weren't getting the same selected compiler version on the form after a failing contract verification.	7 years ago
Igor Florian	44430af6f9	Support multiple compile versions ... This will allow that the versions selected in the page have real impact on how the Contract will be verified.	7 years ago
Tim Mecklem	7bde015bb1	Improve average block time query ... This change limits the results that Postgres uses to evaluate the window. Only `WHERE`, `HAVING`, and `GROUP BY` are used to constrain an `OVER` (not `LIMIT`), so the change to the subquery in the `FROM` clause effectively limits the result set to the number of blocks to include in the average result plus one. We could also use the (timestamp of the most recent + the timestamp of the oldest block) / the count of records returned, but that query requires casts from interval to integer and back to achieve the same result. The window query ends up being similar in how it communicates.	7 years ago

Tim Mecklem	36b3f2af78	Remove unused skipped blocks query from `Expolorer.Chain.Statistics`	7 years ago
Igor Florian	a94ad57fd2	Include solc-js as a dependency ... It executes the solc-js compiler instead of the C version in the app. Even though it's not the more appropriated way to compile solidity `solc-js` will allows us compiling all versions from the beginning.	7 years ago

Luke Imhoff	948516e5e2	Regression test for #309	7 years ago
Luke Imhoff	45529f7346	Dedupe and log duplicate transaction hashes before fetching internal ... Fixes #289 I can't reliably reproduce #289 using the transaction hash or the block number alone, so a fix for the proximate cause of duplicate `transaction_hashes` being passed to `InternalTransactionFetcher.run/2` by passing only the unique transaction hashes to `EthereumJSONRPC.fetch_internal_transactions` while logging the duplicates as errors.	7 years ago

Luke Imhoff	0680973e64	fetched_balance_block_number instead of fetched_balance_at ... Fixes #243 Instead of getting the address balance at the latest block and recording the timestamp of the insert, which is only loosely correlated with even the latest block's timestamp on-chain, use the block number for the last time an address was used in the indexed address foreign keys in the chain: * blocks * miner_hash * internal_transactions * created_contract_address_hash * from_address_hash * to_address_hash * logs * address_hash * transactions * from_address_hash * to_address_hash To gather `fetched_balance_block_number` on reboot, `Explorer.Chain.stream_unfetched_addresses` queries across the above columns for the `MAX(blocks.number)`, which is used in `Explorer.Indexer.AddressBalanceFetcher.init/2`. During indexing, `Explorer.Indexer.AddressBalanceFetcher.async_fetch_balances/1` now requires a list of `%{block_number: Block.block_number(), hash: Hash.Truncated.t()}` instead of list of `Hash.Truncated.t()`. Having a `block_number` available for all importable entities's addresses required changing `Explorer.Indexer.AddressExtraction` to extract the `block_number` too. The use of `insert` in the factories was making tests that show the count not make sense, so the factories were switched to `build` because it means only the exact count is created when a default value is overridden. This does, unfortunately, mean that `params_for(factory)` no longer generates foreign keys and they must be set explicitly OR the association passed instead of the foreign key. Allow nil extracted fetched_balance_block_number when pending transaction *NOTE*: This is a database drop and reindex change.	7 years ago

Luke Imhoff	554f4c6f92	Log chunk and options when insert_all fails ... This will make it easier to diagnose why the insert_all failed as currently, we can't see the data that caused the problem.	7 years ago
