             Summary: 4xx and 5xx HTTP status codes are silently masked as 200
                 Key: LIBCLOUD-901
                 URL: https://issues.apache.org/jira/browse/LIBCLOUD-901
             Project: Libcloud
          Issue Type: Bug
            Reporter: Richard Xia


I'm seeing this on the latest trunk as well as v2.0.0rc1-tentative. When I try to upload an object to AWS S3 using the {{upload_object_via_stream}} method and there is an error (I'll create a separate ticket for that, which I've also determined the cause of), {{libcloud}} will ignore the 5xx error response from {{requests}} and set the status to the default of 200.

The reason this occurs is because the constructor of {{RawResponse}} has an optional argument {{response}} which has a default value of {{None}}. The body of the constructor checks [{{if response}}|https://github.com/apache/libcloud/blob/516018d050a5470afe4a07d33d1fcb26d0e1df18/libcloud/common/base.py#L285] to check if a response was passed into the constructor, but it turns out that the {{requests}} library [overloads the {{__nonzero__}}/{{__bool__}} methods|https://github.com/kennethreitz/requests/issues/2002] to return {{False}} if the response status code is 4xx or 5xx. This [has been fixed|https://github.com/kennethreitz/requests/pull/2587] in the 3.0 branch of {{requests}}, but version 3.0 hasn't been released yet, so this currently affects all versions of requests.

I will submit a pull request with the small change to fix this.
