Chris Ziogas	2ad150d986	eth/tracers: add native flatCallTracer (aka parity style tracer) (#26377) ... Adds support for a native call tracer with the Parity format, which outputs call frames in a flat array. This tracer accepts the following options: - `convertParityErrors: true` will convert error messages to match those of Parity - `includePrecompiles: true` will report all calls to precompiles. The default matches Parity's behavior where CALL and STATICCALLs to precompiles are excluded Incompatibilities with Parity include: - Parity removes the result object in case of failure. This behavior is maintained with the exception of reverts. Revert output usually contains useful information, i.e. Solidity revert reason. - The `gasUsed` field accounts for intrinsic gas (e.g. 21000 for simple transfers) and refunds unlike Parity - Block rewards are not reported Co-authored-by: Sina Mahmoodi <itz.s1na@gmail.com>	2 years ago
Martin Holst Swende	2c6dda5ad7	eth/tracers: use non-threaded tracechain (#24283) ... This makes non-JS tracers execute all block txs on a single goroutine. In the previous implementation, we used to prepare every tx pre-state on one goroutine, and then run the transactions again with tracing enabled. Native tracers are usually faster, so it is faster overall to use their output as the pre-state for tracing the next transaction. Co-authored-by: Sina Mahmoodi <itz.s1na@gmail.com>	2 years ago
Sina Mahmoodi	86de2e516e	eth/tracers: add onlyTopCall option to callTracer (#25430) ... This PR allows users to pass in a config object directly to the tracers. Previously only the struct logger was configurable. It also adds an option to the call tracer which if enabled makes it ignore any subcall and collect only information about the top-level call. See #25419 for discussion. The tracers will silently ignore if they are passed a config they don't care about.	2 years ago
