## EIP-1559 testing
|
|
|
|
This test contains testcases for EIP-1559, which uses an new transaction type and has a new block parameter.
|
|
|
|
### Prestate
|
|
|
|
The alloc portion contains one contract (`0x000000000000000000000000000000000000aaaa`), containing the
|
|
following code: `0x58585454`: `PC; PC; SLOAD; SLOAD`.
|
|
|
|
Essentially, this contract does `SLOAD(0)` and `SLOAD(1)`.
|
|
|
|
The alloc also contains some funds on `0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b`.
|
|
|
|
## Transactions
|
|
|
|
There are two transactions, each invokes the contract above.
|
|
|
|
1. EIP-1559 ACL-transaction, which contains the `0x0` slot for `0xaaaa`
|
|
2. Legacy transaction
|
|
|
|
## Execution
|
|
|
|
Running it yields:
|
|
```
|
|
$ dir=./testdata/9 && ./evm t8n --state.fork=London --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --trace 2>/dev/null && cat trace-* | grep SLOAD
|
|

|
|

|
|
{"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|

|
|
{"pc":3,"op":84,"gas":"0x494c0","gasCost":"0x834","memSize":0,"stack":["0x0","0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
{"pc":4,"op":84,"gas":"0x48456","gasCost":"0x64","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
```
|
|
|
|
We can also get the post-alloc:
|
|
```
|
|
$ dir=./testdata/9 && ./evm t8n --state.fork=London --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout 2>/dev/null
|
|
{
|
|
"alloc": {
|
|
"0x000000000000000000000000000000000000aaaa": {
|
|
"code": "0x58585454",
|
|
"balance": "0x3",
|
|
"nonce": "0x1"
|
|
},
|
|
"0x2adc25665018aa1fe0e6bc666dac8fc2697ff9ba": {
|
|
"balance": "0x5bb10ddef6e0"
|
|
},
|
|
"0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b": {
|
|
"balance": "0xff745ee8832120",
|
|
"nonce": "0x2"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
If we try to execute it on older rules:
|
|
```
|
|
dir=./testdata/9 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout
|
|
ERROR(10): Failed signing transactions: ERROR(10): Tx 0: failed to sign tx: transaction type not supported
|
|
```
|
|
|
|
It fails, due to the `evm t8n` cannot sign them in with the given signer. We can bypass that, however,
|
|
by feeding it presigned transactions, located in `txs_signed.json`.
|
|
|
|
```
|
|
dir=./testdata/9 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs_signed.json --input.env=$dir/env.json
|
|

```
|
|
|
|
Number `0` is not applicable, and therefore number `1` has wrong nonce, and both are rejected.
