[New-bugs-announce] [issue6361] I/O object wrappers shouldn't close their underlying file when deleted.

[Alexandre Vassalotti]

New submission from Alexandre Vassalotti <alexandre at peadrop.com>:

Here's an example of the behaviour:

import io

def test(buf):
   textio = io.TextIOWrapper(buf)

buf = io.BytesIO()
test(buf)
print(buf.closed)  # This prints True currently


The problem here is TextIOWrapper closes its buffer when deleted.
BufferedRWPair behalves similarly. The solution is simply to override
the __del__ method of TextIOWrapper inherited from IOBase.
