From c12f4df910e2da1cc5dd28c5c4bbe2d8721e1057 Mon Sep 17 00:00:00 2001 From: Jeffrey Wilcke Date: Wed, 4 Jan 2017 20:17:24 +0100 Subject: params: core, core/vm, miner: 64bit gas instructions 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 --- tests/block_test_util.go | 2 +- tests/state_test_util.go | 2 +- tests/vm_test_util.go | 6 +++--- 3 files changed, 5 insertions(+), 5 deletions(-) (limited to 'tests') diff --git a/tests/block_test_util.go b/tests/block_test_util.go index 470eb7cb7..01539de03 100644 --- a/tests/block_test_util.go +++ b/tests/block_test_util.go @@ -146,7 +146,7 @@ func runBlockTests(homesteadBlock, daoForkBlock, gasPriceFork *big.Int, bt map[s } for name, test := range bt { - if skipTest[name] { + if skipTest[name] /*|| name != "CallingCanonicalContractFromFork_CALLCODE"*/ { glog.Infoln("Skipping block test", name) continue } diff --git a/tests/state_test_util.go b/tests/state_test_util.go index 5469a4c71..e8ab29d14 100644 --- a/tests/state_test_util.go +++ b/tests/state_test_util.go @@ -108,7 +108,7 @@ func runStateTests(chainConfig *params.ChainConfig, tests map[string]VmTest, ski } for name, test := range tests { - if skipTest[name] { + if skipTest[name] /*|| name != "JUMPDEST_Attack"*/ { glog.Infoln("Skipping state test", name) continue } diff --git a/tests/vm_test_util.go b/tests/vm_test_util.go index 25e55886f..1edf0e425 100644 --- a/tests/vm_test_util.go +++ b/tests/vm_test_util.go @@ -129,7 +129,7 @@ func runVmTests(tests map[string]VmTest, skipTests []string) error { } for name, test := range tests { - if skipTest[name] /*|| name != "loop_stacklimit_1021"*/ { + if skipTest[name] /*|| name != "exp0"*/ { glog.Infoln("Skipping VM test", name) continue } @@ -229,6 +229,6 @@ func RunVm(statedb *state.StateDB, env, exec map[string]string) ([]byte, []*type vm.PrecompiledContracts = make(map[common.Address]vm.PrecompiledContract) environment, _ := NewEVMEnvironment(true, chainConfig, statedb, env, exec) - ret, err := environment.Call(caller, to, data, gas, value) - return ret, statedb.Logs(), gas, err + ret, g, err := environment.Call(caller, to, data, gas.Uint64(), value) + return ret, statedb.Logs(), new(big.Int).SetUint64(g), err } -- cgit v1.2.3
