Requires VM PR FuelLabs/fuel-vm#881.

Description

Implements execution tracing for blocks/transactions that are already part of the chain state,and exposes this functionality through GraphQL. Also upgrades fuel-vm to not-yet-released 0.60.0.

Example query:

mutation {
  executionTraceBlock(height: "1", trigger: ON_RECEIPT) {
    id, receipts {
      pc, reason, receiptType
    }, status {
      __typename
      ... on TraceSuccessStatus { executionTrace { receiptCount, registers, memoryDiff { start, bytes } } }
      ... on TraceFailureStatus { executionTrace { receiptCount, registers, memoryDiff { start, bytes } } }
    }
  }
}

Heavily work-in-progress, needs:

  • Decision on do we have this for whole blocks only, or single txs, or something more complicated
  • Decision on WASM executor support
  • Tests
  • Docs

Checklist

  • Breaking changes are clearly marked as such in the PR description and changelog: No breaking changes!
  • New behavior is reflected in tests
  • The specification matches the implemented behavior: This is outside spec scope.

Before requesting review
