## EIP-2930 testing
|
|
|
|
This test contains testcases for EIP-2930, which uses transactions with access lists.
|
|
|
|
### Prestate
|
|
|
|
The alloc portion contains one contract (`0x000000000000000000000000000000000000aaaa`), containing the
|
|
following code: `0x5854505854`: `PC ;SLOAD; POP; PC; SLOAD`.
|
|
|
|
Essentially, this contract does `SLOAD(0)` and `SLOAD(3)`.
|
|
|
|
The alloc also contains some funds on `0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b`.
|
|
|
|
## Transactions
|
|
|
|
There are three transactions, each invokes the contract above.
|
|
|
|
1. ACL-transaction, which contains some non-used slots
|
|
2. Regular transaction
|
|
3. ACL-transaction, which contains the slots `1` and `3` in `0x000000000000000000000000000000000000aaaa`
|
|
|
|
## Execution
|
|
|
|
Running it yields:
|
|
```
|
|
dir=./testdata/8 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --trace 2>/dev/null && cat trace-* | grep SLOAD
|
|
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
{"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
{"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
{"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memSize":0,"stack":["0x3"],"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"}
|
|
```
|
|
|
|
Similarly, we can provide the input transactions via `stdin` instead of as file:
|
|
|
|
```
|
|
$ dir=./testdata/8 \
|
|
&& cat $dir/txs.json | jq "{txs: .}" \
|
|
| ./evm t8n --state.fork=Berlin \
|
|
--input.alloc=$dir/alloc.json \
|
|
--input.txs=stdin \
|
|
--input.env=$dir/env.json \
|
|
--trace \
|
|
2>/dev/null \
|
|
&& cat trace-* | grep SLOAD
|
|
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
{"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
{"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
|
|
{"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memSize":0,"stack":["0x3"],"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"}
|
|
```
|
|
|
|
If we try to execute it on older rules:
|
|
```
|
|
$ dir=./testdata/8 && ./evm t8n --state.fork=Istanbul --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json
|
|
ERROR(10): failed signing transactions: ERROR(10): tx 0: failed to sign tx: transaction type not supported
|
|
```
