Łukasz Langa  added the comment:

I agree, the fix needs to be changed. What we probably want is to discover this 
kind of assignment and special-case *that*.

Serhiy Storchaka  added the comment:

PR 4607 doesn't look a correct solution to me. I don't know a precedence of 
calling deepcopy() for a value in __setitem__(). deepcopy() is too heavy, 
calling it can slow down normal cases. Using deepcopy likely means a bad design.

[issue32108] configparser bug: section is emptied if you assign a section to itself

2017-11-21 Thread Simon Lambourn 

New submission from Simon Lambourn :

If you assign a ConfigParser section back to the parent ConfigParser object 
(say after updating the section), the section is emptied.

(I realise now that you don't need to assign the section back to the parent as 
it's a proxy for the section in the parent already - but still it does not 
behave as you would expect):
code: 
from configparser import ConfigParser
config = ConfigParser()
config['test'] = {'key': 'value'}
section = config['test']
section['key'] = 'different'
print("before: config['test'] is %s" % dict(config['test']))
config['test'] = section
print("after: config['test'] is %s" % dict(config['test']))
# the section is now printed as {}
