From 8b57c494908637a5c0e74f8f7a13b3218e026757 Mon Sep 17 00:00:00 2001 From: Jeffrey Wilcke Date: Thu, 2 Feb 2017 15:25:42 +0100 Subject: params: core, core/vm, miner: 64bit gas instructions (#3514) Reworked the EVM gas instructions to use 64bit integers rather than arbitrary size big ints. All gas operations, be it additions, multiplications or divisions, are checked and guarded against 64 bit integer overflows. In additon, most of the protocol paramaters in the params package have been converted to uint64 and are now constants rather than variables. * common/math: added overflow check ops * core: vmenv, env renamed to evm * eth, internal/ethapi, les: unmetered eth_call and cancel methods * core/vm: implemented big.Int pool for evm instructions * core/vm: unexported intPool methods & verification methods * core/vm: added memoryGasCost overflow check and test --- miner/miner.go | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'miner') diff --git a/miner/miner.go b/miner/miner.go index 61cd3e049..83059f4b1 100644 --- a/miner/miner.go +++ b/miner/miner.go @@ -171,7 +171,7 @@ func (self *Miner) HashRate() (tot int64) { } func (self *Miner) SetExtra(extra []byte) error { - if uint64(len(extra)) > params.MaximumExtraDataSize.Uint64() { + if uint64(len(extra)) > params.MaximumExtraDataSize { return fmt.Errorf("Extra exceeds max length. %d > %v", len(extra), params.MaximumExtraDataSize) } self.worker.setExtra(extra) -- cgit v1.2.3
