goodsoft	e02194c738	Simplify gas calculation ... Now `gas` is the amount of gas given to the first opcode in a call, and `gas_used` is the amount of gas left after the last opcode in the call.	6 years ago
goodsoft	c608664601	Use from/to fields from transaction instead of receipt ... Transaction receipt from cpp-ethereum doesn't contain these fields.	6 years ago
goodsoft	1aeea2b9ca	Re-implement Geth JS internal transaction tracer in Elixir ... Currently in Geth variant raw traces are converted into internal_transactions using a custom JS tracer in [1]. cpp-ethereum nodes don't support custom JS tracers and return raw traces regardless of provided parameters. This PR adds an Elixir implementation of the tracer, which is utilized in case raw traces are detected in the response from the node. It was cross-checked for correctness with Geth builtin `callTracer`[2]. In the process some bugs were discovered in the our JS tracer, which will be fixed with a separate PR. Though, unlike JS tracer, we don't have access to EVM internal state during tracing, so additional requests to node are required: transactions and receipts are fetched before tracing, created contract codes and pre-selfdestruct balances are fetched after.

goodsoft	7a6c60ddeb	Handle nil quantities in block decoding routine ... Uncle block fetched using eth_getUncleByBlockHashAndIndex API may have null in their size field. We shouldn't crash in this case.	6 years ago
Valentin	2df25f70f9	ex_abi version bump to 0.2.0	6 years ago
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	ab6111b466	Chunk JSON-RPC batches in case connection times out ... There exists code to ensure long-running batch requests are split into smaller batches in case we receive 504 (Gateway Timeout) errorfrom loadbalancer. This PR adds handling of batches in the same manner in case there either is no balancer, or its timeouts are configured larger than indexer's, and thus the HTTP client library itself times out.	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

Sebastian Abondano	1bdb8c1166	Ganache ignores internal transactions ... Why: * We were using the `EthereumJSONRPC.Geth` variant for Ganache but we recently learned that it doesn't support the `tracer` option for [debug_traceTransaction](https://github.com/ethereum/go-ethereum/wiki/Management-APIs#debug_tracetransaction). This `tracer` option is what we currently use to fetch internal transactions for Geth. This was the cause of errors as shown on issue 1152 (link below). * Issue link: https://github.com/poanetwork/blockscout/issues/1152 This change addresses the need by: * Creating `EthereumJSONRPC.Ganache`. It ignores fetching beneficiaries, internal transactions, and pending transactions. * Editing ganache config to use the `EthereumJSONRPC.Ganache` variant instead of `EthereumJSONRPC.Geth`. * Updating inaccurate doc in `EthereumJSONRPC.Geth`. It previously said fetching internal transactions was not supported for Geth which is inaccurate.	6 years ago
Sebastian Abondano	f0de6f4b09	Handles Ganache transaction input bug ... Why: * To be able to index transactions, we need to add special handling for a bug in Ganache in which transaction inputs are returned as invalid `DATA` types. For details please see: https://github.com/trufflesuite/ganache/issues/997 * Issue link: https://github.com/poanetwork/blockscout/issues/1068 This change addresses the need by: * Editing `EthereumJSONRPC.Transaction` to convert incorrectly formatted transaction `input`s of `0x0` to `0x`.	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.
