From de39513ced05f120b30b0daa49003982cc6b2426 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pawe=C5=82=20Bylica?= Date: Thu, 6 Dec 2018 14:34:49 +0100 Subject: core, internal, eth, miner, les: Take VM config from BlockChain (#17955) Until this commit, when sending an RPC request that called `NewEVM`, a blank `vm.Config` would be taken so as to set some options, based on the default configuration. If some extra configuration switches were passed to the blockchain, those would be ignored. This PR adds a function to get the config from the blockchain, and this is what is now used for RPC calls. Some subsequent changes need to be made, see https://github.com/ethereum/go-ethereum/pull/17955#pullrequestreview-182237244 for the details of the discussion. --- internal/ethapi/api.go | 8 ++++---- internal/ethapi/backend.go | 2 +- 2 files changed, 5 insertions(+), 5 deletions(-) (limited to 'internal') diff --git a/internal/ethapi/api.go b/internal/ethapi/api.go index 43a33e992..656555b3b 100644 --- a/internal/ethapi/api.go +++ b/internal/ethapi/api.go @@ -683,7 +683,7 @@ type CallArgs struct { Data hexutil.Bytes `json:"data"` } -func (s *PublicBlockChainAPI) doCall(ctx context.Context, args CallArgs, blockNr rpc.BlockNumber, vmCfg vm.Config, timeout time.Duration) ([]byte, uint64, bool, error) { +func (s *PublicBlockChainAPI) doCall(ctx context.Context, args CallArgs, blockNr rpc.BlockNumber, timeout time.Duration) ([]byte, uint64, bool, error) { defer func(start time.Time) { log.Debug("Executing EVM call finished", "runtime", time.Since(start)) }(time.Now()) state, header, err := s.b.StateAndHeaderByNumber(ctx, blockNr) @@ -724,7 +724,7 @@ func (s *PublicBlockChainAPI) doCall(ctx context.Context, args CallArgs, blockNr defer cancel() // Get a new instance of the EVM. - evm, vmError, err := s.b.GetEVM(ctx, msg, state, header, vmCfg) + evm, vmError, err := s.b.GetEVM(ctx, msg, state, header) if err != nil { return nil, 0, false, err } @@ -748,7 +748,7 @@ func (s *PublicBlockChainAPI) doCall(ctx context.Context, args CallArgs, blockNr // Call executes the given transaction on the state for the given block number. // It doesn't make and changes in the state/blockchain and is useful to execute and retrieve values. func (s *PublicBlockChainAPI) Call(ctx context.Context, args CallArgs, blockNr rpc.BlockNumber) (hexutil.Bytes, error) { - result, _, _, err := s.doCall(ctx, args, blockNr, vm.Config{}, 5*time.Second) + result, _, _, err := s.doCall(ctx, args, blockNr, 5*time.Second) return (hexutil.Bytes)(result), err } @@ -777,7 +777,7 @@ func (s *PublicBlockChainAPI) EstimateGas(ctx context.Context, args CallArgs) (h executable := func(gas uint64) bool { args.Gas = hexutil.Uint64(gas) - _, _, failed, err := s.doCall(ctx, args, rpc.PendingBlockNumber, vm.Config{}, 0) + _, _, failed, err := s.doCall(ctx, args, rpc.PendingBlockNumber, 0) if err != nil || failed { return false } diff --git a/internal/ethapi/backend.go b/internal/ethapi/backend.go index c9ffe230c..e23ee03b1 100644 --- a/internal/ethapi/backend.go +++ b/internal/ethapi/backend.go @@ -53,7 +53,7 @@ type Backend interface { GetBlock(ctx context.Context, blockHash common.Hash) (*types.Block, error) GetReceipts(ctx context.Context, blockHash common.Hash) (types.Receipts, error) GetTd(blockHash common.Hash) *big.Int - GetEVM(ctx context.Context, msg core.Message, state *state.StateDB, header *types.Header, vmCfg vm.Config) (*vm.EVM, func() error, error) + GetEVM(ctx context.Context, msg core.Message, state *state.StateDB, header *types.Header) (*vm.EVM, func() error, error) SubscribeChainEvent(ch chan<- core.ChainEvent) event.Subscription SubscribeChainHeadEvent(ch chan<- core.ChainHeadEvent) event.Subscription SubscribeChainSideEvent(ch chan<- core.ChainSideEvent) event.Subscription -- cgit v1.2.3
