Sina Mahmoodi	401354976b	core,eth: call frame tracing (#23087) ... This change introduces 2 new optional methods; `enter()` and `exit()` for js tracers, and makes `step()` optiona. The two new methods are invoked when entering and exiting a call frame (but not invoked for the outermost scope, which has it's own methods). Currently these are the data fields passed to each of them: enter: type (opcode), from, to, input, gas, value exit: output, gasUsed, error The PR also comes with a re-write of the callTracer. As a backup we keep the previous tracing script under the name `callTracerLegacy`. Behaviour of both tracers are equivalent for the most part, although there are some small differences (improvements), where the new tracer is more correct / has more information.	3 years ago

gary rong	b9df7ecdc3	all: seperate consensus error and evm internal error (#20830) ... * all: seperate consensus error and evm internal error There are actually two types of error will be returned when a tranaction/message call is executed: (a) consensus error (b) evm internal error. The former should be converted to a consensus issue, e.g. The sender doesn't enough asset to purchase the gas it specifies. The latter is allowed since evm itself is a blackbox and internal error is allowed to happen. This PR emphasizes the difference by introducing a executionResult structure. The evm error is embedded inside. So if any error returned, it indicates consensus issue happens. And also this PR improve the `EstimateGas` API to return the concrete revert reason if the transaction always fails * all: polish * accounts/abi/bind/backends: add tests * accounts/abi/bind/backends, internal: cleanup error message * all: address comments * core: fix lint * accounts, core, eth, internal: address comments * accounts, internal: resolve revert reason if possible * accounts, internal: address comments	5 years ago
