get block by hash sometimes returns NULL

Problem Description

when trying to get data by block hash (i.e. using eth_getTransactionByBlockHashAndIndex or eth_getBlockByHash) returned response is null, even though the transaction has been broadcasted successfully and receipt has been received (so the block is valid as well as its hash).

The problem happens NOT all the time. Sometimes both methods calls return the result (transaction or block), like in the attached video - this time we could get block data but could not get transaction data. Sometimes both methods fail. Sometimes both are passing, which makes it tricky to test and catch the reason.

Some returns of eth_getBlockByNumber may be wrong

Problem Description

description: There is one block with very strange block info when we use eth_getBlockByNumber

Environmental information

operating system: N/A service: Forge testnet test Code version:

Steps to reproduce

1、curl -H 'Content-Type: application/json' --data '{"method": "eth_getBlockByNumber", "jsonrpc":"2.0", "params":[135134, false], "id": 1}' https://prod-forge.prod.findora.org:8545 | jq . We can get the block hash of 135134 is 0x0ef7bb9a32b72756b5d48f001f78e87798406bce5eaea6dbe09d9f6473a272d1 and we get the stateRoot 0x8133cc87d8f9bc17b3e31deac4cd7fb97e6852a2211e4e3b22fbfccd3874b566

2、curl -H 'Content-Type: application/json' --data '{"method": "eth_getBlockByNumber", "jsonrpc":"2.0", "params":[135135, false], "id": 1}' https://prod-forge.prod.findora.org:8545 | jq . We can find out that the paretHash is 0xac0df09f0699fdaa8af40ce553cd3c03440fc41db47a70ed70e30d86664215f6, which is not match with the previous information. The stateRoot also changes to 0x1fe00727b579c67555fd07079b36e5b97ce92c2486de6656210f147bf21f3bc3 without any transaction.

3、curl -H 'Content-Type: application/json' --data '{"method": "eth_getBlockByNumber", "jsonrpc":"2.0", "params":[135136, false], "id": 1}' https://prod-forge.prod.findora.org:8545 | jq . We can see the parent hash matches the hash of previous block again. The stateRoot changes back to 0x8133cc87d8f9bc17b3e31deac4cd7fb97e6852a2211e4e3b22fbfccd3874b566 without any transaction. This may be a clue.

  • The major changes of this PR Fix the problem that sending that transaction to the main network will result in incorrect nonce

The main reason is because the previous pre-execution logic does not specify the height,, that is, when evm_checktx_nonce does not reach the specified height, nonce will be in the check_tx in +1, and then go to execute execute, this time will be nonce check error
