JavaScript Runtime Options

We use QuickJS JavaScript Engine for JavaScript execution. QuickJS runtime options can be updated with a proposal. A sample proposal would look like:

{
  "actions": [
    {
      "name": "set_js_runtime_options",
      "args": {
        "max_heap_bytes": 1024,
        "max_stack_bytes": 1024,
        "max_execution_time_ms": 1200
      }
    }
  ]
}

Default values are max_heap_bytes = 100 * 1024 * 1024, max_stack_bytes = 1024 * 1024 and max_execution_time_ms = 1000.
