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 --- cmd/evm/main.go | 36 ++++++++++++++++++------------------ 1 file changed, 18 insertions(+), 18 deletions(-) (limited to 'cmd/evm') diff --git a/cmd/evm/main.go b/cmd/evm/main.go index 704469432..2c4329fa5 100644 --- a/cmd/evm/main.go +++ b/cmd/evm/main.go @@ -191,7 +191,7 @@ func run(ctx *cli.Context) error { vmdone := time.Since(tstart) if ctx.GlobalBool(DumpFlag.Name) { - statedb.Commit() + statedb.Commit(true) fmt.Println(string(statedb.Dump())) } vm.StdErrFormat(logger.StructLogs()) @@ -251,7 +251,7 @@ func NewEnv(state *state.StateDB, transactor common.Address, value *big.Int, cfg return env } -// ruleSet implements vm.RuleSet and will always default to the homestead rule set. +// ruleSet implements vm.ChainConfig and will always default to the homestead rule set. type ruleSet struct{} func (ruleSet) IsHomestead(*big.Int) bool { return true } @@ -259,22 +259,22 @@ func (ruleSet) GasTable(*big.Int) params.GasTable { return params.GasTableHomesteadGasRepriceFork } -func (self *VMEnv) RuleSet() vm.RuleSet { return ruleSet{} } -func (self *VMEnv) Vm() vm.Vm { return self.evm } -func (self *VMEnv) Db() vm.Database { return self.state } -func (self *VMEnv) SnapshotDatabase() int { return self.state.Snapshot() } -func (self *VMEnv) RevertToSnapshot(snap int) { self.state.RevertToSnapshot(snap) } -func (self *VMEnv) Origin() common.Address { return *self.transactor } -func (self *VMEnv) BlockNumber() *big.Int { return common.Big0 } -func (self *VMEnv) Coinbase() common.Address { return *self.transactor } -func (self *VMEnv) Time() *big.Int { return self.time } -func (self *VMEnv) Difficulty() *big.Int { return common.Big1 } -func (self *VMEnv) BlockHash() []byte { return make([]byte, 32) } -func (self *VMEnv) Value() *big.Int { return self.value } -func (self *VMEnv) GasLimit() *big.Int { return big.NewInt(1000000000) } -func (self *VMEnv) VmType() vm.Type { return vm.StdVmTy } -func (self *VMEnv) Depth() int { return 0 } -func (self *VMEnv) SetDepth(i int) { self.depth = i } +func (self *VMEnv) ChainConfig() *params.ChainConfig { return params.TestChainConfig } +func (self *VMEnv) Vm() vm.Vm { return self.evm } +func (self *VMEnv) Db() vm.Database { return self.state } +func (self *VMEnv) SnapshotDatabase() int { return self.state.Snapshot() } +func (self *VMEnv) RevertToSnapshot(snap int) { self.state.RevertToSnapshot(snap) } +func (self *VMEnv) Origin() common.Address { return *self.transactor } +func (self *VMEnv) BlockNumber() *big.Int { return common.Big0 } +func (self *VMEnv) Coinbase() common.Address { return *self.transactor } +func (self *VMEnv) Time() *big.Int { return self.time } +func (self *VMEnv) Difficulty() *big.Int { return common.Big1 } +func (self *VMEnv) BlockHash() []byte { return make([]byte, 32) } +func (self *VMEnv) Value() *big.Int { return self.value } +func (self *VMEnv) GasLimit() *big.Int { return big.NewInt(1000000000) } +func (self *VMEnv) VmType() vm.Type { return vm.StdVmTy } +func (self *VMEnv) Depth() int { return 0 } +func (self *VMEnv) SetDepth(i int) { self.depth = i } func (self *VMEnv) GetHash(n uint64) common.Hash { if self.block.Number().Cmp(big.NewInt(int64(n))) == 0 { return self.block.Hash() -- cgit v1.2.3
