    "Fixes insecure use of asserts in cache.py"
    The assert statement is replaced by
    if not condition:
     raise AssertionError.
    As stated in the Python documentation assert statements will not be evaluated
    when the Python code is compiled with optimization flags. This means that these
    checks will not be properly executed and one can in that case call a specific
    method with a completely different HTTP verb. This can result in security
    issues.
