[issue28867] NamedTemporaryFile does not generate a ResourceWarning for unclosed files (unlike TemporaryFile)

[Jon Dufresne]

Jon Dufresne added the comment:

I've taken a new approach to resolve the urllib issues.

I believe HTTPError _should not_ warn when __del__ is called as HTTPError wraps an existing resource instead of generating its own. IIUC, in this case, I believe it falls to the responsibility of code generating the resource to properly close and manage the resource (or pass that responsibility along). If I misunderstood, please let me know.

All feedback on the patch is welcome, thanks.
