Detailed Description

Refuse a read of an attribute only a skipped base `__init__` sets (#8844).

When a class defines `__init__` without calling its base's, an attribute that
only the base `__init__` sets is missing on its instances, and reading it
raises AttributeError. The converter lays out one struct per class with every
inherited attribute, so the read gets a value instead. Such a program is
refused at the class's instantiation when the attribute is read anywhere.

Function Documentation

_ancestors()

preprocessor.skipped_base_init._ancestors ( cls, classes )

protected

The module's classes `cls` derives from, or None when one is defined
elsewhere.

_attribute_uses()

preprocessor.skipped_base_init._attribute_uses ( module, classes )

protected

Attributes stored outside every class's `__init__`, and attributes read.

_calls_an_init()

preprocessor.skipped_base_init._calls_an_init ( fn )

protected

_init()

preprocessor.skipped_base_init._init ( cls )

protected

_missing_attributes()

preprocessor.skipped_base_init._missing_attributes ( cls, classes, outside_stores )

protected

Attributes only a base `__init__` that `cls` skips would set.

_self_stores()

preprocessor.skipped_base_init._self_stores ( fn )

protected

Attributes `fn` stores through its first parameter.

refuse_skipped_base_init()

preprocessor.skipped_base_init.refuse_skipped_base_init	(		module,
			module_name )

Raise NotImplementedError at the instantiation of such a class.
