mypy 0.902

Expected behaviour

Setting "python.linting.mypyArgs": ["--exclude", "tests"] in settings.json disables mypy on the tests/ directory.

Actual behaviour

VSCode detects an error in files under tests/.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

Install mypy
Create a directory tests/
Add a python file in there with a mypy error
Set "python.linting.mypyArgs": ["--exclude", "tests"] in settings.json
Open the file from step 4 and vscode will show a mypy error

When running mypy --exclude tests . in the terminal, mypy will not show an error

The issue is that VS Code is invoking mypy file by file. And mypy doesn’t use the exclude option when invoked on a single file. The workaround is using python.linting.ignorePatterns in the settings.json.

 "python.linting.ignorePatterns": [ "tests/**/*.py" ]

More info about the behaviour of exclude:

Note that this flag only affects recursive discovery, that is, when mypy is discovering files within a directory tree or submodules of a package to check. If you pass a file or module explicitly it will still be checked. For instance, mypy --exclude ‘/setup.py$’ but_still_check/setup.py.

another workaround if you’d prefer to keep linting on in general for a set of files, but disable mypy only, would be to add an empty --exclude to python.linting.mypyArgs. Note there will be significant computational overhead with this approach though since this will result in all non-excluded files (via other configuration, pyproject.toml for instance) being checked for every file checked (every open file with modifications it seems). Any sense of when this bug is targeted for a fix? Thanks!
