Description

As discussed in the comments of this ​PR, we can avoid calling resolve(request.path) in the technical_404_response if request.resolver_match is already set.

This fix first checks if the resolver is None before calling resolve(), and avoids the call entirely if we have already resolved.

caller = ''
if resolver_match is None:
    try:
        resolver_match = resolve(request.path)
    except Http404:
        pass

if resolver_match is not None:
    caller = resolver_match._func_path
