By default, pip uses ``importlib.metadata`` on Python 3.11+, and ``pkg_resources`` otherwise. Up to Python 3.13, This can be overridden by a couple of ways: * If environment variable ``_PIP_USE_IMPORTLIB_METADATA`` is set, it dictates whether ``importlib.metadata`` is used, for Python <3.14. * On Python 3.11, 3.12 and 3.13, Python distributors can patch ``importlib.metadata`` to add a global constant ``_PIP_USE_IMPORTLIB_METADATA = False``. This makes pip use ``pkg_resources`` (unless the user set the aforementioned environment variable to *True*). On Python 3.14+, the ``pkg_resources`` backend cannot be used. )� � T�_PIP_USE_IMPORTLIB_METADATAN�r � Fr ) �sys� version_info� contextlib�suppress�KeyError� ValueErrorr r �os�environ�importlib.metadata�getattr�metadata�� importlib� r& �S/opt/saltstack/salt/lib/python3.10/site-packages/pip/_internal/metadata/__init__.py� _should_use_importlib_metadata s � r( �Nonec C s: t jdk rd S dd l} t| jd�rd S tddddd� d S ) Nr r r z7Using the pkg_resources metadata backend is deprecated.zpto use the default importlib.metadata backend, by unsetting the _PIP_USE_IMPORTLIB_METADATA environment variablez26.3i4 )�reasonZ replacementZgone_inZissue)r r r! �hasattrr# r r$ r& r& r' �)_emit_pkg_resources_deprecation_if_needed< s �r, c @ s& e Zd ZU ded< ded< ded< dS )�Backendz%Literal['importlib', 'pkg_resources']�NAMEztype[BaseDistribution]� Distributionztype[BaseEnvironment]� EnvironmentN)�__name__� __module__� __qualname__�__annotations__r& r& r& r' r- U s r- c C s8 t � rddlm} tt| �S t� ddlm} tt|�S )Nr r$ )� pkg_resources)r( � r% r r- r, r5 )r% r5 r& r& r' r [ s r r c C s t � j�� S )a Get the default representation for the current environment.
