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 --- accounts/abi/bind/backends/simulated.go | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) (limited to 'accounts/abi/bind') diff --git a/accounts/abi/bind/backends/simulated.go b/accounts/abi/bind/backends/simulated.go index bdc2a98bc..f750a1fbd 100644 --- a/accounts/abi/bind/backends/simulated.go +++ b/accounts/abi/bind/backends/simulated.go @@ -31,11 +31,12 @@ import ( "github.com/ethereum/go-ethereum/core/vm" "github.com/ethereum/go-ethereum/ethdb" "github.com/ethereum/go-ethereum/event" + "github.com/ethereum/go-ethereum/params" "golang.org/x/net/context" ) // Default chain configuration which sets homestead phase at block 0 (i.e. no frontier) -var chainConfig = &core.ChainConfig{HomesteadBlock: big.NewInt(0)} +var chainConfig = ¶ms.ChainConfig{HomesteadBlock: big.NewInt(0), EIP150Block: new(big.Int), EIP158Block: new(big.Int)} // This nil assignment ensures compile time that SimulatedBackend implements bind.ContractBackend. var _ bind.ContractBackend = (*SimulatedBackend)(nil) @@ -51,6 +52,8 @@ type SimulatedBackend struct { mu sync.Mutex pendingBlock *types.Block // Currently pending block that will be imported on request pendingState *state.StateDB // Currently pending state that will be the active on on request + + config *params.ChainConfig } // NewSimulatedBackend creates a new binding backend using a simulated blockchain @@ -85,7 +88,7 @@ func (b *SimulatedBackend) Rollback() { } func (b *SimulatedBackend) rollback() { - blocks, _ := core.GenerateChain(nil, b.blockchain.CurrentBlock(), b.database, 1, func(int, *core.BlockGen) {}) + blocks, _ := core.GenerateChain(chainConfig, b.blockchain.CurrentBlock(), b.database, 1, func(int, *core.BlockGen) {}) b.pendingBlock = blocks[0] b.pendingState, _ = state.New(b.pendingBlock.Root(), b.database) } @@ -243,7 +246,7 @@ func (b *SimulatedBackend) SendTransaction(ctx context.Context, tx *types.Transa panic(fmt.Errorf("invalid transaction nonce: got %d, want %d", tx.Nonce(), nonce)) } - blocks, _ := core.GenerateChain(nil, b.blockchain.CurrentBlock(), b.database, 1, func(number int, block *core.BlockGen) { + blocks, _ := core.GenerateChain(chainConfig, b.blockchain.CurrentBlock(), b.database, 1, func(number int, block *core.BlockGen) { for _, tx := range b.pendingBlock.Transactions() { block.AddTx(tx) } -- cgit v1.2.3
