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/instructions.go | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'core/vm/instructions.go') diff --git a/core/vm/instructions.go b/core/vm/instructions.go index 94a8c6348..4f98953b5 100644 --- a/core/vm/instructions.go +++ b/core/vm/instructions.go @@ -515,7 +515,7 @@ func opCreate(instr instruction, pc *uint64, env Environment, contract *Contract input = memory.Get(offset.Int64(), size.Int64()) gas = new(big.Int).Set(contract.Gas) ) - if env.RuleSet().GasTable(env.BlockNumber()).CreateBySuicide != nil { + if env.ChainConfig().IsEIP150(env.BlockNumber()) { gas.Div(gas, n64) gas = gas.Sub(contract.Gas, gas) } @@ -526,7 +526,7 @@ func opCreate(instr instruction, pc *uint64, env Environment, contract *Contract // homestead we must check for CodeStoreOutOfGasError (homestead only // rule) and treat as an error, if the ruleset is frontier we must // ignore this error and pretend the operation was successful. - if env.RuleSet().IsHomestead(env.BlockNumber()) && suberr == CodeStoreOutOfGasError { + if env.ChainConfig().IsHomestead(env.BlockNumber()) && suberr == CodeStoreOutOfGasError { stack.push(new(big.Int)) } else if suberr != nil && suberr != CodeStoreOutOfGasError { stack.push(new(big.Int)) -- cgit
