It appears that 2.3 changed how socket.close() works.
We now find errors when terminating Python when we
reference socket.close() in a __del__ method. We have
worked around it by removing calls to socket.close() but
note the following differences between the same section
of code between 2.2 and 2.3 which suggest that the 2.3
behavior is not ideal and should be fixed.
In Python 2.3:
def close(self):
self._sock = _closedsocket()
self.send = self.recv = self.sendto = self.recvfrom \
= self._sock._dummy
In Python 2.2:
def close(self):
# Avoid referencing globals here
self._sock = self.__class__._closedsocket()
Note the reference to avoiding globals which is
presumably the source of the problem with 2.3. Perhaps
I'm naive but I would guess that calling a close method
should be considered a safe operation for use in a
__del__ method.
