Arran Schlosberg 12b8aa5c2e fix: pre-state tracer logging storage after call from precompile (#64) ... ## Why this should be merged Fixes tracing when a stateful precompile calls another contract that itself accesses storage. ## How this works The pre-state tracer from `eth/tracers/native` doesn't implement `CaptureEnter()` (entry of a new context), instead relying on `CaptureState()` (per-opcode tracing) to detect that a new contract has been entered. In doing so, it [maintains an invariant](cb7eb89341/eth/tracers/native/prestate.go (L160)) that is expected when `CaptureState(vm.SLOAD, ...)` is called—breaking the invariant results in a panic due to a nil map. The fix involves (a) maintaining the invariant as part of `CaptureEnter()` (previously a no-op); and (b) calling said method inside `vm.PrecompileEnvironment.Call()`. The latter has the added benefit of properly handling all tracing involving an outbound call from precompiles. ## How this was tested New integration test demonstrates that the tracer can log the retrieved storage value. --------- Co-authored-by: Darioush Jalali <darioush.jalali@avalabs.org>		2024-10-29 17:26:29 +11:00
