- mypy_test and pyright no longer just test the stubs, they now also test other parts of typeshed as well.
- pytype_test.py can now be run on 3.10, meaning the whole test suite can now also be run on 3.10.
- Various test scripts now have from `__future__ import annotations`, meaning they can now only be run on 3.7+.
- Clean up the description of pyright_test.py, which had a slightly confusing wording.
- Also fix the `--dry-run` config option in mypy_test.py, which I accidentally broke in #7746
- Add several type hints to untyped functions.
- While we're at it, upgrade several annotations to use modern syntax by using `from __future__ import annotations`. This means that the tests can't be run on Python 3.6, but 3.6 is EOL, and it is already the case that some scripts in this directory can only be run on more recent Python versions. E.g. `check_new_syntax.py` uses `ast.unparse`, which is only available in Python 3.9+.
- Fix a few pieces of code that didn't type check.
`--enable-error-code ignore-without-code` means that mypy will ignore any type: ignore comments that don't have mypy error codes. It doesn't appear to have any effect on type: ignore comments that mypy_test doesn't use (e.g. because they're pyright- or stubtest-specific).
`--strict-equality` means that mypy will raise errors if we do something silly like `if sys.version_info == "linux"`. flake8-pyi should also check this for us, but I don't see any reason not to have mypy check this as well.
* Run mypy on the 3.11 stdlib in CI, as a regression test for https://github.com/python/mypy/issues/12220
* Correct the docstring at the top of the file following the changes made in #7478
* Stop the test from crashing when run locally if there's an extra file/folder in the stubs directory.
* Fix `mypy_test.py` so that it actually tests the third-party stubs
* Upgrade to mypy 0.940
* Skip running mypy on `SQLAlchemy` stubs for now, to workaround a mypy crash.
Because we didn't set mypy's clean_exit parameter, it was exiting immediately after checking the stdlib, meaning `mypy_test.py` wasn't checking the third-party stubs at all.

* Remove --strict-optional: This has been the default since mypy 0.600.
* Remove --disallow-subclassing-any: When we subclass Any in typeshed,
we do so deliberately. This just causes us to add unncessary ignores.
Only print the mypy command twice per version: Once for the stdlib and
once for the stubs. Use a dummy /tmp path. Add a header for each tested
Python version and remove the Python version from the individual stubs.
* Mark stdlib modules with upper version bounds
* Add minus to all versions and enforce in check_consistent
* Fix check_consistent and mypy_test to work with new VERSIONS format
As requested by https://github.com/python/typeshed/issues/1526.
This addition takes mypy configuration from each distribution metadata file and constructs a single mypy.ini to run with. It assumes there is no mypy.ini but in case we ever need one, it would be simple to add these on top of an existing configuration file.
Might be relevant for #2852
As the issue did not really specify how the configuration would look, I added the following:
- You may add a mypy-tests section to the metadata file.
It looks like this:
[mypy-tests]
[mypy-tests.yaml]
module_name = "yaml"
[mypy-tests.yaml.values]
disallow_incomplete_defs = true
disallow_untyped_defs = true
- module_name can be of the form "a.*" like in mypy.ini.
- You can add several module sections for complex distributions with several modules.
- I added the '--warn-incomplete-stub' option since it is made specifically for typeshed runs. See docs.
This replaces all uses of ‘blacklist’ with ‘exclude list’. Benefits:
- It is racially neutral terminology; see e.g. [1]
- It makes the meaning more clear. In fact, with the popular Python
autoformatter called ‘black’, also used by this project, files can be
‘blackened’ which is something completely different from them being on
a blacklist.
