twisted.web.http and twisted.web.client handle HTTP status inconsistently.

New submission from nejucomo <None>:

The twisted.web.http.Request.setResponseCode() method requires an int argument to represent the HTTP status code to send to a client.

On the other hand, the twisted.web.client.HTTPClientFactory.deferred errback fires with a Failure whose .value.status contains a string representing the HTTP status code in the response from a server.  (The errback fires when this status is an error status, such as a 404.)

I assumed I could pass the contents of a Failure to a Request (server-side response) but this raised a type error.  A simplified example of the code would look like this:

{{{
def errback(reason):
    assert the_reason_represents_a_404_error_response(reason)
    myRequest.setResponseCode(reason.value.status)


cfac = HTTPClientFactory('http://www.google.com/nonexistent_path_wombat')
cfac.deferred.addCallbacks(normalHandler, errback)
reactor.connectTCP(cfac.host, cfac.port, cfac)
}}}
