Issue 26469: Bug in ConfigParser when setting new values in extended interpolation (original) (raw)

There seems to be a bug in configparser when setting new values in extended interpolation:

python --version Python 3.5.1

from configparser import ConfigParser, ExtendedInterpolation c=ConfigParser(interpolation=ExtendedInterpolation) c.add_section('test') c.set('test', 'key', 'value') Traceback (most recent call last): File "", line 1, in File "/usr/lib/python3.5/configparser.py", line 1190, in set super().set(section, option, value) File "/usr/lib/python3.5/configparser.py", line 891, in set value) TypeError: before_set() missing 1 required positional argument: 'value'

It works ithout extended interpolation, though.
