Hmm, why is vendoring explicitly tied to Python 3.8? ping @pradyunsg

[error]Version spec 3.9 for architecture x64 did not match any version in Agent.ToolsDirectory.

Hey Azure, you鈥檙e late.

Travis is late too.

@McSinyx sits back and waits.

Every CI provider will take a while to add these in. That's the usual story around every Python release. :)

I think I'd meant to allow ~= 3.8, soooo... released a fix. :)

Congratulations on being careful to exclude Python 4, just in case it's backward incompatible 馃檪 Lazy me would have just done >= 3.8... (I had to look up ~= to confirm what it meant!)

Hah. GitHub Actions seems to actually have a good plan for Python releases now. Edited OP to add links to relevant CI providers.

@uranusjr FYI - the work being done for in Azure/azure-functions-python-worker#753 is only specific to Azure Functions.
For Azure Devops, the work does is documented in actions/runner-images#1740 (comment)

Suggestion: split out the developer tooling changes into a separate PR, keeping the CI matrix + documentation parts here. That'll let us move forward on the CI as-and-when the providers update, while still letting us do development on Py3.9, as necessary. :)

python/mypy#8627

tl;dr need to upgarde pre-commit hook to use mypy >= 0.780

At first use it for GitHub Action for linting.
HashError.order is now annotated as an int to allow
HashErrors.errors.sort(key=lambda e: e.order).  Alternatively we can
define a function which assert e is not None but I prefer the more
concise version, since we never raise HashError directly anyway.

Thanks, I pinned mypy to 0.790 (the latest release).

Yup. Travis is green, it鈥檚 the hook having trouble reporting back (as it often does). The only part I鈥檓 not sure about is the change of vendoring specifier from == to >=, I鈥檒l leave this for @pradyunsg to judge since he knows about vendoring best.

195: Update pip to 20.3 r=duckinator a=pyup-bot


This PR updates [pip](https://pypi.org/project/pip) from **20.2.4** to **20.3**.



<details>
  <summary>Changelog</summary>
  
  
   ### 20.3
   ```
   - Introduce a new ResolutionImpossible error, raised when pip encounters un-satisfiable dependency conflicts (`8546 &lt;https://github.com/pypa/pip/issues/8546&gt;`_, `8377 &lt;https://github.com/pypa/pip/issues/8377&gt;`_)
- Add a subcommand ``debug`` to ``pip config`` to list available configuration sources and the key-value pairs defined in them. (`6741 &lt;https://github.com/pypa/pip/issues/6741&gt;`_)
- Warn if index pages have unexpected content-type (`6754 &lt;https://github.com/pypa/pip/issues/6754&gt;`_)
- Allow specifying ``--prefer-binary`` option in a requirements file (`7693 &lt;https://github.com/pypa/pip/issues/7693&gt;`_)
- Generate PEP 376 REQUESTED metadata for user supplied requirements installed
  by pip. (`7811 &lt;https://github.com/pypa/pip/issues/7811&gt;`_)
- Warn if package url is a vcs or an archive url with invalid scheme (`8128 &lt;https://github.com/pypa/pip/issues/8128&gt;`_)
- Parallelize network operations in ``pip list``. (`8504 &lt;https://github.com/pypa/pip/issues/8504&gt;`_)
- Allow the new resolver to obtain dependency information through wheels
  lazily downloaded using HTTP range requests.  To enable this feature,
  invoke ``pip`` with ``--use-feature=fast-deps``. (`8588 &lt;https://github.com/pypa/pip/issues/8588&gt;`_)
- Support ``--use-feature`` in requirements files (`8601 &lt;https://github.com/pypa/pip/issues/8601&gt;`_)

Bug Fixes
---------

- Use canonical package names while looking up already installed packages. (`5021 &lt;https://github.com/pypa/pip/issues/5021&gt;`_)

- Correctly treat non-ASCII entry point declarations in wheels so they can be
  installed on Windows. (`8342 &lt;https://github.com/pypa/pip/issues/8342&gt;`_)
- Update author email in config and tests to reflect decommissioning of pypa-dev list. (`8454 &lt;https://github.com/pypa/pip/issues/8454&gt;`_)
- Headers provided by wheels in .data directories are now correctly installed
  into the user-provided locations, such as ``--prefix``, instead of the virtual
  environment pip is running in. (`8521 &lt;https://github.com/pypa/pip/issues/8521&gt;`_)

   ```
   
  
  
   ### 20.3b1
   ```
   ===================

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

- ``pip freeze`` will stop filtering the ``pip``, ``setuptools``, ``distribute`` and ``wheel`` packages from ``pip freeze`` output in a future version.
  To keep the previous behavior, users should use the new ``--exclude`` option. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Deprecate support for Python 3.5 (`8181 &lt;https://github.com/pypa/pip/issues/8181&gt;`_)
- Document that certain removals can be fast tracked. (`8417 &lt;https://github.com/pypa/pip/issues/8417&gt;`_)
- Document that Python versions are generally supported until PyPI usage falls below 5%. (`8927 &lt;https://github.com/pypa/pip/issues/8927&gt;`_)
- Deprecate ``--find-links`` option in ``pip freeze`` (`9069 &lt;https://github.com/pypa/pip/issues/9069&gt;`_)

Features
--------

- Add ``--exclude`` option to ``pip freeze`` and ``pip list`` commands to explicitly exclude packages from the output. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Allow multiple values for --abi and --platform. (`6121 &lt;https://github.com/pypa/pip/issues/6121&gt;`_)
- Add option ``--format`` to subcommand ``list`` of ``pip  cache``, with ``abspath`` choice to output the full path of a wheel file. (`8355 &lt;https://github.com/pypa/pip/issues/8355&gt;`_)
- Improve error message friendliness when an environment has packages with
  corrupted metadata. (`8676 &lt;https://github.com/pypa/pip/issues/8676&gt;`_)
- Make the ``setup.py install`` deprecation warning less noisy. We warn only
  when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as
  situations where both fails are most probably irrelevant to this deprecation. (`8752 &lt;https://github.com/pypa/pip/issues/8752&gt;`_)
- Check the download directory for existing wheels to possibly avoid
  fetching metadata when the ``fast-deps`` feature is used with
  ``pip wheel`` and ``pip download``. (`8804 &lt;https://github.com/pypa/pip/issues/8804&gt;`_)
- When installing a git URL that refers to a commit that is not available locally
  after git clone, attempt to fetch it from the remote. (`8815 &lt;https://github.com/pypa/pip/issues/8815&gt;`_)
- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`8892 &lt;https://github.com/pypa/pip/issues/8892&gt;`_)
- Cache package listings on index packages so they are guarenteed to stay stable
  during a pip command session. This also improves performance when a index page
  is accessed multiple times during the command session. (`8905 &lt;https://github.com/pypa/pip/issues/8905&gt;`_)
- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)
- Log an informational message when backtracking takes multiple rounds on a specific package. (`8975 &lt;https://github.com/pypa/pip/issues/8975&gt;`_)
- Switch to the new dependency resolver by default. (`9019 &lt;https://github.com/pypa/pip/issues/9019&gt;`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

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

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

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

- Add documentation for &#39;.netrc&#39; support. (`7231 &lt;https://github.com/pypa/pip/issues/7231&gt;`_)
- Add OS tabs for OS-specific commands. (`7311 &lt;https://github.com/pypa/pip/issues/7311&gt;`_)
- Add note and example on keyring support for index basic-auth (`8636 &lt;https://github.com/pypa/pip/issues/8636&gt;`_)
- Added initial UX feedback widgets to docs. (`8783 &lt;https://github.com/pypa/pip/issues/8783&gt;`_, `8848 &lt;https://github.com/pypa/pip/issues/8848&gt;`_)
- Add ux documentation (`8807 &lt;https://github.com/pypa/pip/issues/8807&gt;`_)
- Update user docs to reflect new resolver as default in 20.3. (`9044 &lt;https://github.com/pypa/pip/issues/9044&gt;`_)
- Improve migration guide to reflect changes in new resolver behavior. (`9056 &lt;https://github.com/pypa/pip/issues/9056&gt;`_)

  situations where both fails are most probably irrelevant to this deprecation. (`8752 &lt;https://github.com/pypa/pip/issues/8752&gt;`_)
- Check the download directory for existing wheels to possibly avoid
  fetching metadata when the ``fast-deps`` feature is used with
  ``pip wheel`` and ``pip download``. (`8804 &lt;https://github.com/pypa/pip/issues/8804&gt;`_)
- When installing a git URL that refers to a commit that is not available locally
  after git clone, attempt to fetch it from the remote. (`8815 &lt;https://github.com/pypa/pip/issues/8815&gt;`_)
- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`8892 &lt;https://github.com/pypa/pip/issues/8892&gt;`_)
- Cache package listings on index packages so they are guarenteed to stay stable
  during a pip command session. This also improves performance when a index page
  is accessed multiple times during the command session. (`8905 &lt;https://github.com/pypa/pip/issues/8905&gt;`_)
- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)

- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

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

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`8892 &lt;https://github.com/pypa/pip/issues/8892&gt;`_)
- Cache package listings on index packages so they are guarenteed to stay stable
  during a pip command session. This also improves performance when a index page
  is accessed multiple times during the command session. (`8905 &lt;https://github.com/pypa/pip/issues/8905&gt;`_)
- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)
- Log an informational message when backtracking takes multiple rounds on a specific package. (`8975 &lt;https://github.com/pypa/pip/issues/8975&gt;`_)
- Switch to the new dependency resolver by default. (`9019 &lt;https://github.com/pypa/pip/issues/9019&gt;`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

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

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

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

- Add documentation for &#39;.netrc&#39; support. (`7231 &lt;https://github.com/pypa/pip/issues/7231&gt;`_)
- Add OS tabs for OS-specific commands. (`7311 &lt;https://github.com/pypa/pip/issues/7311&gt;`_)
- Add note and example on keyring support for index basic-auth (`8636 &lt;https://github.com/pypa/pip/issues/8636&gt;`_)
- Added initial UX feedback widgets to docs. (`8783 &lt;https://github.com/pypa/pip/issues/8783&gt;`_, `8848 &lt;https://github.com/pypa/pip/issues/8848&gt;`_)
- Add ux documentation (`8807 &lt;https://github.com/pypa/pip/issues/8807&gt;`_)
- Update user docs to reflect new resolver as default in 20.3. (`9044 &lt;https://github.com/pypa/pip/issues/9044&gt;`_)
- Improve migration guide to reflect changes in new resolver behavior. (`9056 &lt;https://github.com/pypa/pip/issues/9056&gt;`_)
