[New-bugs-announce] [issue21579] Python 3.4: tempfile.close attribute does not work

New submission from Марк Коренберг:

Suppose code:
import os
import tempfile

want_to_replace = 'zxc.dat'
with tempfile.NamedTemporaryFile(dir=tmpdir) as fff:
    # do somewhat with fff here... and then:
    os.rename(fff.name, want_to_replace)
    fff.delete = False
In python 3.3 and lower that works FINE. In Python 3.4 the fff._closer attribute was introduced, so fff.close=False stopped to work. I think this is major loss of functionality. The "close" attribute was not marked as private, so may be used in past.
