Description

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.

Proposal
