From 7f22b59f87cfda85a14eed6481da68e3dfba44a1 Mon Sep 17 00:00:00 2001 From: Felix Lange Date: Tue, 23 Oct 2018 21:51:41 +0200 Subject: core/state: simplify proof methods (#17965) This fixes the import cycle build error in core/vm tests. There is no need to refer to core/vm for a type definition. --- core/state/statedb.go | 20 +++++++++++++------- 1 file changed, 13 insertions(+), 7 deletions(-) (limited to 'core/state') diff --git a/core/state/statedb.go b/core/state/statedb.go index b1bb53ed0..f0d7cdb6e 100644 --- a/core/state/statedb.go +++ b/core/state/statedb.go @@ -26,7 +26,6 @@ import ( "github.com/ethereum/go-ethereum/common" "github.com/ethereum/go-ethereum/core/types" - "github.com/ethereum/go-ethereum/core/vm" "github.com/ethereum/go-ethereum/crypto" "github.com/ethereum/go-ethereum/log" "github.com/ethereum/go-ethereum/rlp" @@ -46,6 +45,13 @@ var ( emptyCode = crypto.Keccak256Hash(nil) ) +type proofList [][]byte + +func (n *proofList) Put(key []byte, value []byte) error { + *n = append(*n, value) + return nil +} + // StateDBs within the ethereum protocol are used to store anything // within the merkle trie.
