A few lines up, back at L:157, there's if err == nil, where the clause which does setCode is performed. I suggest to check MaxCodeSize up there instead of down here, and then also skip the SetCode stuff.

You can use RawSignatureValues here (and below). The point of this check is to see whether the fields were set in JSON.

I think this should be RawSignatureValues. The v, r, s JSON fields are new in 1.5 and we can define the semantics for them. Raw values are preferable here because the client should be able to reconstruct the whole transaction.
e.g. if you do
client, _ := ethclient.Dial("http://127.0.0.1:8085")
tx, _ := client.TransactionByHash(ctx, common.HexToHash("...."))
from, _ := types.Sender(types.NewEIP155Signer(signer), tx))The from value should be the same as it was on the server. Normalising the values breaks this.

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 <[email protected]>

@obscuren please fix the go vet issue |
This PR implements the EIP158 proposal and EIP160.
It also changes the location where the chain configuration is kept to the
paramspackage. This is done so that any time a HF proposal is added or if the chain config needs modification, only a single location needs to be changed. This also means that thevm.Environmentno longer has aRuleSetbut aChainConfigdirectly. All locations in the tests wherecore.GenerateChaintook anilparameter for theChainConfigare now passingparams.TestChainConfig.ChainConfigis no longer optional, it is an requirement. Passingnilanywhere (as done in mostGenerateChaincalls) will result in a hard panic.Note for reviewers: please make sure that a
params.TestChainConfigis suitable for your tests. It has the following parameters:homestead = 0, dao = 0, daoEnabled = true, EIP150 = true, EIP158 = true.TODO list
core.ChainConfigand moved toparamspackage instead
