goodsoft	8e6ee4ceb1	Use eth_getUncleByBlockHashAndIndex for uncle block fetching ... Parity returns `null` for many uncle blocks, if they are fetched using `eth_getBlockByHash`. This is most probably caused by the fact that Parity only keeps full block data for recent non-consensus blocks. This causes uncle_block fetcher to loop endlessly trying to fetch "missing" blocks, hogging both app server and Parity resources. Instead, we use `eth_getUncleByBlockHashAndIndex` method, which works for all uncle blocks. As we didn't previously store index of an uncle block within a nephew block, a new field and a temporary fixup fetcher is added to get the index from nephew blocks.	6 years ago

goodsoft	ea3af5e299	Use transaction-level fetch_internal_transactions for Geth ... Internal transaction fetcher is split into two APIs: * `fetch_block_internal_transactions` is used for Parity * `fetch_internal_transactions` is used for the rest of variants `Indexer.InternalTransaction.Fetcher` is updated to take care of that.	6 years ago
Paul Tsupikoff	2a8def19e2	Allow executing smart contract functions in arbitrarily sized batches ... # Problem There are a lot of `getBalanceOf` token function calls during indexing blockchain. Each of them is sent as a separate JSONRPC request, which creates a lot of unnecessary overhead and clogs archive node workers, which could otherwise be busy performing other JSONRPC queries. Moreover, function name is used as the `id` parameter of JSONRPC queries, which doesn't allow us to simply put multiple requests into one batch. # Solution * Change `EthereumJSONRPC.execute_contract_functions` to accept a list of arbitrary function calls and return a list of results. * Handle `id` field generation in the `EthereumJSONRPC` package instead of leaking implementation details to `Explorer.SmartContract.Reader`. * Change `Token.BalanceReader.get_balance_of` to accept a list of parameter sets and return a list of balances. * Make one batch request instead of launching multiple concurrent tasks in `Indexer.TokenBalances.fetch_token_balances_from_blockchain` # Notes * Protocol details of calling smart contract functions is now fully encapsulated in `EthereumJSONRPC` package. * `SmartContract.Reader.query_contract` is left for backwards compatibility with other existing applications of smart contract requests, but can be fully deprecated at some later time.	6 years ago
Luke Imhoff	8135fcafbd	Allow lists of block numbers instead of ranges for beneficiares ... Simplifies calling as numbers don't need to grouped into ranges when getting numbers from database.	6 years ago

Luke Imhoff	97ce8e838b	Don't reference Explorer types in EthereumJSONRPC ... EthereumJSONRPC is not supposed to depend on Explorer at a code level, it should at most cross reference it in docs.	6 years ago

Luke Imhoff	3499155cdb	Partial retries for fetch_blocks_by_range ... Means that both Block.Fetchers, realtime and catchup, now handle fetch errors. The Block.Catchup.Fetcher will retry those blocks that failed to fetch while importing the rest that did fetch instead of refetching the whole batch.	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	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
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

Amanda Sposito	dae9ff2f10	Add support to Pluggable Transport and HTTP transport modules	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	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	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
Luke Imhoff	466c1e76f6	Request transport module and options for all JSONRPC calls ... To lessen load on Sokol chain nodes during testing and to allow substituting different transports than HTTP, such as IPC, in the future, pass the transport module and its options to any call to `EthereumJSONRPC.json_rpc`. This will allow us to use a `mox` module in local testing, so we only do true chain integration testing in CircleCI.	6 years ago
Luke Imhoff	3c680ff953	Log, but do not fail tests, when 502 Bad Gateway occurs ... 502 Bad Gateway is an intermittent problem that needs to be fixed by ops when the JSONRPC servers are under heavy load, so they should not fail the test runs.	6 years ago

Luke Imhoff	cac1cab39c	Geth receipts compatibility ... When testing transaction receipt processing using Geth against Ethereum Mainnet, a number of missing features were discovered: * Support for `to` and `from` addresses in receipts * The need to derive status for pre-Byzantium transactions by using the supplied gas from the transaction and the gasUsed in the receipt to check for out-of-gas.	6 years ago
Luke Imhoff	72373f7770	method_to_url config ... Instead of making up symbolic names for the different types of URLs we need, have the configuration be a base `url` for a fallback and then entries under `method_to_url` which maps a JSONRPC method name to a the URL to use. This allows the devops running the JSONRPC nodes to say which nodes support which methods specifically, which is easier than knowing which symbolic name uses which methods. It also means we don't need separate variant specific symbolic names since the variants will be able to use their own method names in this new format for the config.	6 years ago
Luke Imhoff	d946b0d073	EthereumJSONRPC.Variant behaviour ... Define which callbacks and the types needed for each variant of the JSONRPC, so it is easier to add support for new variants in the future.	6 years ago

Luke Imhoff	e44a617a55	Rechunk batch JSONRPC request when 413 is returned ... When status 413 Request Entity Too Large is returned from JSONRPC, we can split the batch in half and try again. Continuing to break up the chunks of the batch until we suceed or hit 1 request in the chunk, in which case we still need to error.	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
