Update pip to 22.1.1

[pyup-bot]

This PR updates pip from 21.3.1 to 22.1.1.

Changelog

22.1.1

===================

Bug Fixes
---------

- Properly filter out optional dependencies (i.e. extras) when checking build environment distributions. (`11112 <https://github.com/pypa/pip/issues/11112>`_)
- Change the build environment dependency checking to be opt-in. (`11116 <https://github.com/pypa/pip/issues/11116>`_)
- Allow using a pre-release version to satisfy a build requirement. This helps
manually populated build environments to more accurately detect build-time
requirement conflicts. (`11123 <https://github.com/pypa/pip/issues/11123>`_)

22.1

=================

Process
-------

- Enable the ``importlib.metadata`` metadata implementation by default on
Python 3.11 (or later). The environment variable ``_PIP_USE_IMPORTLIB_METADATA``
can still be used to enable the implementation on 3.10 and earlier, or disable
it on 3.11 (by setting it to ``0`` or ``false``).

Bug Fixes
---------

- Revert `9243 <https://github.com/pypa/pip/issues/9243>`_ since it introduced a regression in certain edge cases. (`#10962 <https://github.com/pypa/pip/issues/10962>`_)
- Fix missing ``REQUESTED`` metadata when using URL constraints. (`11079 <https://github.com/pypa/pip/issues/11079>`_)
- ``pip config`` now normalizes names by converting underscores into dashes. (`9330 <https://github.com/pypa/pip/issues/9330>`_)

22.1b1

===================

Process
-------

- Start migration of distribution metadata implementation from ``pkg_resources``
to ``importlib.metadata``. The new implementation is currently not exposed in
any user-facing way, but included in the code base for easier development.

Deprecations and Removals
-------------------------

- Drop ``--use-deprecated=out-of-tree-build``, according to deprecation message. (`11001 <https://github.com/pypa/pip/issues/11001>`_)

- Add support for Powershell autocompletion. (`9024 <https://github.com/pypa/pip/issues/9024>`_)
- Explains why specified version cannot be retrieved when *Requires-Python* is not satisfied. (`9615 <https://github.com/pypa/pip/issues/9615>`_)
- Validate build dependencies when using ``--no-build-isolation``. (`9794 <https://github.com/pypa/pip/issues/9794>`_)

Bug Fixes
---------

- Fix conditional checks to prevent ``pip.exe`` from trying to modify itself, on Windows. (`10560 <https://github.com/pypa/pip/issues/10560>`_)
- Fix uninstall editable from Windows junction link. (`10696 <https://github.com/pypa/pip/issues/10696>`_)
- Fallback to pyproject.toml-based builds if ``setup.py`` is present in a project, but ``setuptools`` cannot be imported. (`10717 <https://github.com/pypa/pip/issues/10717>`_)
- When checking for conflicts in the build environment, correctly skip requirements
containing markers that do not match the current environment. (`10883 <https://github.com/pypa/pip/issues/10883>`_)
- Disable brotli import in vendored urllib3 so brotli could be uninstalled/upgraded by pip. (`10950 <https://github.com/pypa/pip/issues/10950>`_)
- Prioritize URL credentials over netrc. (`10979 <https://github.com/pypa/pip/issues/10979>`_)
- Filter available distributions using hash declarations from constraints files. (`9243 <https://github.com/pypa/pip/issues/9243>`_)

- Fix pip install issues using a proxy due to an inconsistency in how Requests is currently handling variable precedence in session. (`9691 <https://github.com/pypa/pip/issues/9691>`_)

Vendored Libraries
------------------

- Upgrade CacheControl to 0.12.11
- Upgrade distro to 1.7.0
- Upgrade platformdirs to 2.5.2
- Remove ``progress`` from vendored dependencies.
- Upgrade ``pyparsing`` to 3.0.8 for startup performance improvements.
- Upgrade rich to 12.2.0
- Upgrade tomli to 2.0.1
- Upgrade typing_extensions to 4.2.0

Improved Documentation
----------------------

- Add more dedicated topic and reference pages to the documentation. (`10899 <https://github.com/pypa/pip/issues/10899>`_)
- Capitalise Y as the default for "Proceed (y/n)?" when uninstalling. (`10936 <https://github.com/pypa/pip/issues/10936>`_)
- Add ``scheme://`` requirement to ``--proxy`` option's description (`10951 <https://github.com/pypa/pip/issues/10951>`_)
- The wheel command now references the build interface section instead of stating the legacy
setuptools behavior as the default. (`10972 <https://github.com/pypa/pip/issues/10972>`_)
- Improved usefulness of ``pip config --help`` output. (`11074 <https://github.com/pypa/pip/issues/11074>`_)

22.0.4

===================

Deprecations and Removals
-------------------------

- Drop the doctype check, that presented a warning for index pages that use non-compliant HTML 5. (`10903 <https://github.com/pypa/pip/issues/10903>`_)

Vendored Libraries
------------------

- Downgrade distlib to 0.3.3.

22.0.3

===================

Features
--------

- Print the exception via ``rich.traceback``, when running with ``--debug``. (`10791 <https://github.com/pypa/pip/issues/10791>`_)

Bug Fixes
---------

- Only calculate topological installation order, for packages that are going to be installed/upgraded.

This fixes an `AssertionError` that occured when determining installation order, for a very specific combination of upgrading-already-installed-package + change of dependencies + fetching some packages from a package index. This combination was especially common in Read the Docs' builds. (`10851 <https://github.com/pypa/pip/issues/10851>`_)
- Use ``html.parser`` by default, instead of falling back to ``html5lib`` when ``--use-deprecated=html5lib`` is not passed. (`10869 <https://github.com/pypa/pip/issues/10869>`_)

Improved Documentation
----------------------

- Clarify that using per-requirement overrides disables the usage of wheels. (`9674 <https://github.com/pypa/pip/issues/9674>`_)

22.0.2

===================

Deprecations and Removals
-------------------------

- Instead of failing on index pages that use non-compliant HTML 5, print a deprecation warning and fall back to ``html5lib``-based parsing for now. This simplifies the migration for non-compliant index pages, by letting such indexes function with a warning. (`10847 <https://github.com/pypa/pip/issues/10847>`_)

22.0.1

===================

Bug Fixes
---------

- Accept lowercase ``<!doctype html>`` on index pages. (`10844 <https://github.com/pypa/pip/issues/10844>`_)
- Properly handle links parsed by html5lib, when using ``--use-deprecated=html5lib``. (`10846 <https://github.com/pypa/pip/issues/10846>`_)

22.0

=================

Process
-------

- Completely replace :pypi:`tox` in our development workflow, with :pypi:`nox`.

Deprecations and Removals
-------------------------

- Deprecate alternative progress bar styles, leaving only ``on`` and ``off`` as available choices. (`10462 <https://github.com/pypa/pip/issues/10462>`_)
- Drop support for Python 3.6. (`10641 <https://github.com/pypa/pip/issues/10641>`_)
- Disable location mismatch warnings on Python versions prior to 3.10.

These warnings were helping identify potential issues as part of the sysconfig -> distutils transition, and we no longer need to rely on reports from older Python versions for information on the transition. (`10840 <https://github.com/pypa/pip/issues/10840>`_)

Features
--------

- Changed ``PackageFinder`` to parse HTML documents using the stdlib :class:`html.parser.HTMLParser` class instead of the ``html5lib`` package.

For now, the deprecated ``html5lib`` code remains and can be used with the ``--use-deprecated=html5lib`` command line option. However, it will be removed in a future pip release. (`10291 <https://github.com/pypa/pip/issues/10291>`_)
- Utilise ``rich`` for presenting pip's default download progress bar. (`10462 <https://github.com/pypa/pip/issues/10462>`_)
- Present a better error message when an invalid wheel file is encountered, providing more context where the invalid wheel file is. (`10535 <https://github.com/pypa/pip/issues/10535>`_)
- Documents the ``--require-virtualenv`` flag for ``pip install``. (`10588 <https://github.com/pypa/pip/issues/10588>`_)
- ``pip install <tab>`` autocompletes paths. (`10646 <https://github.com/pypa/pip/issues/10646>`_)
- Allow Python distributors to opt-out from or opt-in to the ``sysconfig`` installation scheme backend by setting ``sysconfig._PIP_USE_SYSCONFIG`` to ``True`` or ``False``. (`10647 <https://github.com/pypa/pip/issues/10647>`_)
- Make it possible to deselect tests requiring cryptography package on systems where it cannot be installed. (`10686 <https://github.com/pypa/pip/issues/10686>`_)
- Start using Rich for presenting error messages in a consistent format. (`10703 <https://github.com/pypa/pip/issues/10703>`_)
- Improve presentation of errors from subprocesses. (`10705 <https://github.com/pypa/pip/issues/10705>`_)
- Forward pip's verbosity configuration to VCS tools to control their output accordingly. (`8819 <https://github.com/pypa/pip/issues/8819>`_)

Bug Fixes
---------

- Optimize installation order calculation to improve performance when installing requirements that form a complex dependency graph with a large amount of edges. (`10557 <https://github.com/pypa/pip/issues/10557>`_)
- When a package is requested by the user for upgrade, correctly identify that the extra-ed variant of that same package depended by another user-requested package is requesting the same package, and upgrade it accordingly. (`10613 <https://github.com/pypa/pip/issues/10613>`_)
- Prevent pip from installing yanked releases unless explicitly pinned via the ``==`` or ``===`` operators. (`10617 <https://github.com/pypa/pip/issues/10617>`_)
- Stop backtracking on build failures, by instead surfacing them to the user and aborting immediately. This behaviour provides more immediate feedback when a package cannot be built due to missing build dependencies or platform incompatibility. (`10655 <https://github.com/pypa/pip/issues/10655>`_)
- Silence ``Value for <location> does not match`` warning caused by an erroneous patch in Slackware-distributed Python 3.9. (`10668 <https://github.com/pypa/pip/issues/10668>`_)
- Fix an issue where pip did not consider dependencies with and without extras to be equal (`9644 <https://github.com/pypa/pip/issues/9644>`_)
