From 781915f183c6e09474c6192d1aaba8e99c4990de Mon Sep 17 00:00:00 2001 From: Nick Johnson Date: Fri, 19 Aug 2016 15:19:51 +0100 Subject: core/vm: Refactor tracing to make Tracer the main interface This CL makes several refactors: - Define a Tracer interface, implementing the `CaptureState` method - Add the VM environment as the first argument of `Tracer.CaptureState` - Rename existing functionality `StructLogger` an make it an implementation of `Tracer` - Delete `StructLogCollector` and make `StructLogger` collect the logs directly - Change all callers to use the new `StructLogger` where necessary and extract logs from that. - Deletes the apparently obsolete and likely nonfunctional 'TraceCall' from the eth API. Callers that only wish accumulated logs can use the `StructLogger` implementation straightforwardly. Callers that wish to efficiently capture VM traces and operate on them without excessive copying can now implement the `Tracer` interface to receive VM state at each step and do with it as they wish. This CL also removes the accumulation of logs from the vm.Environment; this was necessary as part of the refactor, but also simplifies it by removing a responsibility that doesn't directly belong to the Environment. --- tests/util.go | 10 ---------- 1 file changed, 10 deletions(-) (limited to 'tests') diff --git a/tests/util.go b/tests/util.go index 8d1917d15..79c3bfad1 100644 --- a/tests/util.go +++ b/tests/util.go @@ -166,8 +166,6 @@ type Env struct { difficulty *big.Int gasLimit *big.Int - logs []vm.StructLog - vmTest bool evm *vm.EVM @@ -181,14 +179,6 @@ func NewEnv(ruleSet RuleSet, state *state.StateDB) *Env { return env } -func (self *Env) StructLogs() []vm.StructLog { - return self.logs -} - -func (self *Env) AddStructLog(log vm.StructLog) { - self.logs = append(self.logs, log) -} - func NewEnvFromMap(ruleSet RuleSet, state *state.StateDB, envValues map[string]string, exeValues map[string]string) *Env { env := NewEnv(ruleSet, state) -- cgit v1.2.3
