Another possible fix:
def __getattr__(self, name):
if name != 'db' and self.db:
return getattr(self.db, name)
raise _int_error('Connection is not valid')
This would raise an InternalErrorwhen self.db is accessed, but not set.
In __del__ we could then check for that error:
def __del__(self):
try:
db = self.db
except (AttributeError, InternalError):
db = None
if db:
db.set_cast_hook(None)
if self._closeable:
db.close()
