[Pywikipedia-bugs] [Maniphest] [Created] T212741: classes derived from object should always call super in Initializer

[Xqt]

Xqt created this task. Xqt added a project: Pywikibot. Restricted Application added subscribers: pywikibot-bugs-list, Aklapper.

TASK DESCRIPTION

If a class is derived from multiple instances, the initializer must alway call ist super initializer even the class is derived from object. Otherwise the MRO chain is broken:

>>> class foo(object):
	def __init__(self):
		print('foo')
		
>>> class bar(object):
	def __init__(self):
		print('bar')
		
>>> class baz(foo, bar):
	def __init__(self):
		print('baz')
		super(baz, self).__init__()

>>> x = baz()
baz
foo

bar initializer isn't called here whereas the following works as expected:

>>> class foo(object):
	def __init__(self):
		print('foo')
		super(foo, self).__init__()

>>> class bar(object):
	def __init__(self):
		print('bar')
		super(bar, self).__init__()

>>> class baz(foo, bar):
	def __init__(self):
		print('baz')
		super(baz, self).__init__()

>>> x = baz()
baz
foo
bar
