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.

Luke Imhoff	60b02b4604	Add trace addresses to Geth tracer output ... Andrew explained that the trace address from Parity is the index of each nested call. I can compute that as I flatten the tree into a sequence.	6 years ago
Luke Imhoff	e4b7a4ee5f	Geth internal transactions ... Get internal transactions using debug_traceTransaction and a custom tracer. The tracer was based on the callTracer that ships with Geth, but rewritten to break it into more functions with more explicit purpose and to patch some holes in callTracer: * All calls have gas and gasUsed, which patches the hole in callTracer for handling `DELEGATECALL`. * All calls have value, which patches the hole in callTracer for handling `DELEGATECALL` and `STATICALL`. Since the tracer needed to be resubmitted in whole anyway, it was further customized to match the format needed for internal transactions: * Instead of returning the `op` as `type`, the `type` and `callType` used for internal transactions is returned. * Instead of returning a call tree, the tree is walked in pre-order, displaying the parent call before its nested calls to match the flat order returned from parity's trace_transaction.	6 years ago
