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

Jeffrey Wilcke	361082ec4b	cmd/evm, core/vm, test: refactored VM and core ... * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * core/vm: byte code VM moved to jump table instead of switch * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * Byte code VM now shares the same code as the JITVM * Renamed Context to Contract * Changed initialiser of state transition & unexported methods * Removed the Execution object and refactor `Call`, `CallCode` & `Create` in to their own functions instead of being methods. * Removed the hard dep on the state for the VM. The VM now depends on a Database interface returned by the environment. In the process the core now depends less on the statedb by usage of the env * Moved `Log` from package `core/state` to package `core/vm`.	9 years ago
