     1  ## EIP-2930 testing
     2  
     3  This test contains testcases for EIP-2930, which uses transactions with access lists. 
     4  
     5  ### Prestate
     6  
     7  The alloc portion contains one contract (`0x000000000000000000000000000000000000aaaa`), containing the 
     8  following code: `0x5854505854`: `PC ;SLOAD; POP; PC; SLOAD`.
     9  
    10  Essentialy, this contract does `SLOAD(0)` and `SLOAD(3)`.
    11  
    12  The alloc also contains some funds on `0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b`. 
    13  
    14  ## Transactions
    15  
    16  There are three transactions, each invokes the contract above. 
    17  
    18  1. ACL-transaction, which contains some non-used slots
    19  2. Regular transaction
    20  3. ACL-transaction, which contains the slots `1` and `3` in `0x000000000000000000000000000000000000aaaa`
    21  
    22  ## Execution 
    23  
    24  Running it yields: 
    25  ```
    26  dir=./testdata/8 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --trace && cat trace-* | grep SLOAD
    27  {"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    28  {"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    29  {"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    30  {"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    31  {"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    32  {"pc":4,"op":84,"gas":"0x48456","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    33  
    34  ```
    35  
    36  Simlarly, we can provide the input transactions via `stdin` instead of as file: 
    37  
    38  ```
    39  dir=./testdata/8 \
    40    && cat $dir/txs.json | jq "{txs: .}" \
    41    | ./evm t8n --state.fork=Berlin \
    42       --input.alloc=$dir/alloc.json \
    43       --input.txs=stdin \
    44       --input.env=$dir/env.json \
    45       --trace  \
    46    && cat trace-* | grep SLOAD
    47  
    48  {"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    49  {"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    50  {"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    51  {"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    52  {"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    53  {"pc":4,"op":84,"gas":"0x48456","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    54  ```
    55  
    56  If we try to execute it on older rules: 
    57  ```
    58  dir=./testdata/8 && ./evm t8n --state.fork=Istanbul --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json 
    59  INFO [01-21|23:21:51.265] rejected tx                              index=0 hash=d2818d..6ab3da error="tx type not supported"

    62  ```
    63  Number `1` and `3` are not applicable, and therefore number `2` has wrong nonce.
