bpo-26175: Fix SpooledTemporaryFile IOBase abstract by GFernie · Pull Request #3249 · python/cpython

@GFernie 

One would assume that this class implements the IOBase abstract. As the
underlying file-like object is either io.BytesIO, io.StringIO, or a true
file object, this is a reasonable abstract expect and to implement.

Regardless, the behaviour of this class does not change much in the case
of the attribute being missing from the underlying file-like; an
AttributeError is still raised, albeit from one additional frame on the
stack trace.

We don't want to delete the underlying file explicitly as the expected
behaviour is for the file to be deleted *after* it falls out of scope.
