[issue18879] tempfile.NamedTemporaryFile can close the file too early, if not assigning to a variable

[Jakub Stasiak]

Jakub Stasiak added the comment:

I don't see an obvious way of solving that. One thing I could think of is creating a wrapper for file method being returned from __getattr__ that holds reference to _TemporaryFileWrapper instance until the method gets called, please find a patch attached.
