New submission from STINNER Victor <victor.stin...@haypocalc.com>:
The following code raise a ValueError('I/O operation on closed file.'):
---
import socket
socket.socket(socket.SOCK_STREAM, socket.AF_INET)
s=socket.socket(socket.SOCK_STREAM, socket.AF_INET)
f=s.makefile("rb")
f.close()
print(repr(f))
---
io.BufferedReader.__repr__() reads self.name (self.buffer.name), but
self.buffer is closed.
io.BufferedReader.__repr__() catchs AttributeError when reading self.name. It
should also maybe catch ValueError: attached patch does that.
socket.repr(x) returns a string with "[closed]". BufferedReader.repr() should
maybe do the same.
Note: TextIOWrapper has the same issue.
