From 445feaeef58bd89a113743dccf6fd5df55cde6fa Mon Sep 17 00:00:00 2001 From: Jeffrey Wilcke Date: Thu, 20 Oct 2016 13:36:29 +0200 Subject: core, core/state, trie: EIP158, reprice & skip empty account write This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke --- core/vm/runtime/env.go | 43 ++++++++++++++++++++++--------------------- 1 file changed, 22 insertions(+), 21 deletions(-) (limited to 'core/vm/runtime/env.go') diff --git a/core/vm/runtime/env.go b/core/vm/runtime/env.go index 59fbaa792..f1a2b60d3 100644 --- a/core/vm/runtime/env.go +++ b/core/vm/runtime/env.go @@ -23,13 +23,14 @@ import ( "github.com/ethereum/go-ethereum/core" "github.com/ethereum/go-ethereum/core/state" "github.com/ethereum/go-ethereum/core/vm" + "github.com/ethereum/go-ethereum/params" ) // Env is a basic runtime environment required for running the EVM. type Env struct { - ruleSet vm.RuleSet - depth int - state *state.StateDB + chainConfig *params.ChainConfig + depth int + state *state.StateDB origin common.Address coinbase common.Address @@ -47,14 +48,14 @@ type Env struct { // NewEnv returns a new vm.Environment func NewEnv(cfg *Config, state *state.StateDB) vm.Environment { env := &Env{ - ruleSet: cfg.RuleSet, - state: state, - origin: cfg.Origin, - coinbase: cfg.Coinbase, - number: cfg.BlockNumber, - time: cfg.Time, - difficulty: cfg.Difficulty, - gasLimit: cfg.GasLimit, + chainConfig: cfg.ChainConfig, + state: state, + origin: cfg.Origin, + coinbase: cfg.Coinbase, + number: cfg.BlockNumber, + time: cfg.Time, + difficulty: cfg.Difficulty, + gasLimit: cfg.GasLimit, } env.evm = vm.New(env, vm.Config{ Debug: cfg.Debug, @@ -65,16 +66,16 @@ func NewEnv(cfg *Config, state *state.StateDB) vm.Environment { return env } -func (self *Env) RuleSet() vm.RuleSet { return self.ruleSet } -func (self *Env) Vm() vm.Vm { return self.evm } -func (self *Env) Origin() common.Address { return self.origin } -func (self *Env) BlockNumber() *big.Int { return self.number } -func (self *Env) Coinbase() common.Address { return self.coinbase } -func (self *Env) Time() *big.Int { return self.time } -func (self *Env) Difficulty() *big.Int { return self.difficulty } -func (self *Env) Db() vm.Database { return self.state } -func (self *Env) GasLimit() *big.Int { return self.gasLimit } -func (self *Env) VmType() vm.Type { return vm.StdVmTy } +func (self *Env) ChainConfig() *params.ChainConfig { return self.chainConfig } +func (self *Env) Vm() vm.Vm { return self.evm } +func (self *Env) Origin() common.Address { return self.origin } +func (self *Env) BlockNumber() *big.Int { return self.number } +func (self *Env) Coinbase() common.Address { return self.coinbase } +func (self *Env) Time() *big.Int { return self.time } +func (self *Env) Difficulty() *big.Int { return self.difficulty } +func (self *Env) Db() vm.Database { return self.state } +func (self *Env) GasLimit() *big.Int { return self.gasLimit } +func (self *Env) VmType() vm.Type { return vm.StdVmTy } func (self *Env) GetHash(n uint64) common.Hash { return self.getHashFn(n) } -- cgit
