"""Mixin for handling the astroid cache problems.
|
|
|
|
When clearing the astroid cache, some tests fails due to
|
|
cache inconsistencies, where some objects had a different
|
|
builtins object referenced.
|
|
This saves the builtins module and makes sure to add it
|
|
back to the astroid_cache after the tests finishes.
|
|
The builtins module is special, since some of the
|
|
transforms for a couple of its objects (str, bytes etc)
|
|
are executed only once, so astroid_bootstrapping will be
|
|
useless for retrieving the original builtins module.
