I am using in WSGI applications, using Apache and mod_wsgi. Unfortunately keeps spamming the error log with messages like the following:

Exception ignored in: <bound method FieldStorage.__del__ of FieldStorage(None, None, [])>
Traceback (most recent call last):
  File "/usr/lib/python3.5/", line 566, in __del__
NameError: name 'AttributeError' is not defined

This is mostly likely due to the warning about __del__ in <>, i.e. AttributeError will already have been cleaned at the time FieldStorage is collected. One workaround that seems to work for me is to cache AttributeError in the constructor of FieldStorage in self and use that attribute during __del__.

Same issue here (python 3.6). This is very annoying, especially in case of large entries in FieldStorage, because the whole data is written to the log.

    FieldStorage('image', 'upload.jpg', b'...can be very long...')

There's been quite a few changes in finalization (thanks to Victor) since 3.5/3.6. 

Are you seeing this problem on 3.9+? 

Can you provide instructions how to reproduce it?

All my projects now use werkzeug instead of the cgi module, so I can't confirm whether this problem still exists. I'm fine with closing this as unreproducible if no one else can reproduce it.

Thanks Sebastian, I'll close this and if someone still sees this problem they will report it.
