Verify how wasmd reacts when gas runs out during execution #8

ethanfrey · 2020-01-08T15:37:30Z

Summary

We should test two cases:

infinite loop in wasm, that runs out of gas in cpu cycles
loop on kvstore access, gas runs out when calling into go KVStore code

Problem Definition

In both cases, the tx should return an error, and not panic the wasmd process.

We also should ensure the cosmwasm-vm is not left in an invalid state. You can test this by calling a second tx to the same contract - ideally one that shouldn't fail. If we leave an invalid contract state inside the LRU cache, we will have problems, otherwise there should be no influence between consequtive runs.

Test finished

I just finish the loop test in contract, for two case:
- infinite loop:
  - request succeeded
  - wasmd not crash or any error output
  - got right result
- infinite KV store access
  - request succeeded
  - wasmd not crash or any error output
  - got right result
    I use escrow contract to test this case, i added the follow code:

fn try_infinite_op() -> Result<Response>{
    let mut ticket = 0u128;
    loop {
        ticket += 1;
        if ticket >= 9000000000 {
            ticket = 0;
        }
    }
}

fn try_infinite_kv_access<T: Storage>(s : &mut T) -> Result<Response>{
    let mut test_case = 0u128;
    loop {
        s.set("test.key".as_bytes(),test_case.to_string().as_bytes());
        test_case += 1;     //whatever the increment will large than U128::MAX
    }
}

and then, I add test code in func "try_approve" :

if amount.first().unwrap().amount.parse::<u32>().unwrap()== 1000{
    //need infinite loop
   try_infinite_op();
 }else if amount.first().unwrap().amount.parse::<u32>().unwrap() == 2000 {
   try_infinite_kv_access(storage);
}

so, I test it by wasmcli

 APPROVE='{"approve":{"quantity":[{"amount":"2000","denom":"stake"}]}}'
 wasmcli tx wasm execute fred $CONTRACT "$APPROVE" -y
 APPROVE='{"approve":{"quantity":[{"amount":"1000","denom":"stake"}]}}'
 wasmcli tx wasm execute fred $CONTRACT "$APPROVE" -y

all request return succeeded, after then, i try to approve other amount, the contract working correctly, but when I use ctrl+c to kill wasmd, some crash report showed up (it repeated every time):

Got another SIGINT before trap is triggered on WebAssembly side, aborting

Hi @KamiD Thank you for this test case.

It sounds like we handle gas limit properly... but then I see that you said "request succeeded". It should "succeed" in that you get a response, but the response should be "out of gas", correct? I like the way you make these conditional checks by the way. I will add them to a test contract.

For the second issue of ugly stack traces. This seems to be not a crash, persay, but poor handling of shutdown. I came across this in tests and thought it was a rust panic, then found out that anytime the process dies, this gets dumped out (nil pointer error in go). Digging in a bit deeper, I realize there is some conflict between the unix signal handlers for tendermint and wasmer: #4 (comment)

I will dig into that later, but it seems to just produce ugly shutdown messages and not crashes in running processes (but it does make finding cause of crash harder)

Hi @ethanfrey I didn't see log "out of gas"
in-fact, approve operation was success, money already transferred to target account, the raw log is :
