From 342ae7ce7dfd7a0eab2dd06bfa65199825279f05 Mon Sep 17 00:00:00 2001 From: Jeffrey Wilcke Date: Thu, 21 Jan 2016 15:29:58 +0100 Subject: core, core/vm, tests: changed the initialisation behaviour of the EVM The EVM was previously initialised and created for every CALL, CALLCODE, DELEGATECALL and CREATE. This PR changes this behaviour so that the same EVM can be used through the session and beyond as long as the Environment sticks around. --- cmd/evm/main.go | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'cmd/evm/main.go') diff --git a/cmd/evm/main.go b/cmd/evm/main.go index ef679e373..0ba6820e0 100644 --- a/cmd/evm/main.go +++ b/cmd/evm/main.go @@ -33,6 +33,7 @@ import ( "github.com/ethereum/go-ethereum/core/vm" "github.com/ethereum/go-ethereum/ethdb" "github.com/ethereum/go-ethereum/logger/glog" + "github.com/ethereum/go-ethereum/params" ) var ( @@ -174,17 +175,23 @@ type VMEnv struct { Gas *big.Int time *big.Int logs []vm.StructLog + + evm *vm.Vm } func NewEnv(state *state.StateDB, transactor common.Address, value *big.Int) *VMEnv { - return &VMEnv{ + params.HomesteadBlock = new(big.Int) + env := &VMEnv{ state: state, transactor: &transactor, value: value, time: big.NewInt(time.Now().Unix()), } + env.evm = vm.EVM(env) + return env } +func (self *VMEnv) Vm() *vm.Vm { return self.evm } func (self *VMEnv) Db() vm.Database { return self.state } func (self *VMEnv) MakeSnapshot() vm.Database { return self.state.Copy() } func (self *VMEnv) SetSnapshot(db vm.Database) { self.state.Set(db.(*state.StateDB)) } -- cgit v1.2.3 From 14013372aeca2d7f1d8c3a87b7df7c27868314be Mon Sep 17 00:00:00 2001 From: Jeffrey Wilcke Date: Wed, 3 Feb 2016 23:46:27 +0100 Subject: core: Added EVM configuration options The EVM is now initialised with an additional configured object that allows you to turn on debugging options. --- cmd/evm/main.go | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) (limited to 'cmd/evm/main.go') diff --git a/cmd/evm/main.go b/cmd/evm/main.go index 0ba6820e0..2cc70d81b 100644 --- a/cmd/evm/main.go +++ b/cmd/evm/main.go @@ -106,7 +106,6 @@ func init() { } func run(ctx *cli.Context) { - vm.Debug = ctx.GlobalBool(DebugFlag.Name) vm.ForceJit = ctx.GlobalBool(ForceJitFlag.Name) vm.EnableJit = !ctx.GlobalBool(DisableJitFlag.Name) @@ -119,7 +118,9 @@ func run(ctx *cli.Context) { receiver := statedb.CreateAccount(common.StringToAddress("receiver")) receiver.SetCode(common.Hex2Bytes(ctx.GlobalString(CodeFlag.Name))) - vmenv := NewEnv(statedb, common.StringToAddress("evmuser"), common.Big(ctx.GlobalString(ValueFlag.Name))) + vmenv := NewEnv(statedb, common.StringToAddress("evmuser"), common.Big(ctx.GlobalString(ValueFlag.Name)), &vm.Config{ + Debug: ctx.GlobalBool(DebugFlag.Name), + }) tstart := time.Now() ret, e := vmenv.Call( @@ -176,10 +177,10 @@ type VMEnv struct { time *big.Int logs []vm.StructLog - evm *vm.Vm + evm *vm.EVM } -func NewEnv(state *state.StateDB, transactor common.Address, value *big.Int) *VMEnv { +func NewEnv(state *state.StateDB, transactor common.Address, value *big.Int, cfg *vm.Config) *VMEnv { params.HomesteadBlock = new(big.Int) env := &VMEnv{ state: state, @@ -187,11 +188,13 @@ func NewEnv(state *state.StateDB, transactor common.Address, value *big.Int) *VM value: value, time: big.NewInt(time.Now().Unix()), } - env.evm = vm.EVM(env) + cfg.Logger.Collector = env + + env.evm = vm.New(env, cfg) return env } -func (self *VMEnv) Vm() *vm.Vm { return self.evm } +func (self *VMEnv) Vm() vm.Vm { return self.evm } func (self *VMEnv) Db() vm.Database { return self.state } func (self *VMEnv) MakeSnapshot() vm.Database { return self.state.Copy() } func (self *VMEnv) SetSnapshot(db vm.Database) { self.state.Set(db.(*state.StateDB)) } -- cgit v1.2.3
