#17225 Sandboxes when executing mypy and pyright differ Issue created by smelc Describe the bug When I run the backend

pants.backend.python.typecheck.mypy

and the backend

pants.backend.experimental.python.typecheck.pyright

, the sandboxes obtained are different: they don't contain the same amount of my code. The

pyright

sandbox is missing some sources compared to the

mypy

sandbox. Given the following repo:

├── BUILD
├── kaiko
│   └── geometry
│       ├── *.py
├── requirements.txt
├── tests
    ├── BUILD
    ├── test_*.py

with the top-level BUILD file being:

python_requirements(name="kaiko-geometry-reqs")

python_sources(
    name="kaiko-geometry",
    sources=["kaiko/geometry/**/*.py"],
    dependencies=[
        ":kaiko-geometry-reqs#numpy",
    ],
)

and the BUILD file in

tests

being:

python_tests(
    name="kaiko-geometry-tests",
    dependencies=[
        "//:kaiko-geometry-reqs",
        "//:kaiko-geometry",
    ],
)

python_test_utils(
    name="kaiko-geometry-test-utils",
    dependencies=[
        "//:kaiko-geometry-reqs",
        "//:kaiko-geometry",
    ],
)

I obtain such a sandbox with the

mypy

backend:

├── kaiko
│   └── geometry
│       ├── *.py
└── tests
    ├── test_*.py

while the sandbox obtained with the

pyright

backend is:

tests/
├── *.py

i.e. the

kaiko/geometry

folder is missing. In both cases, I ran the command

PANTS_SHA=20ac158e6dc50821fb465a0d3f67f96c8079a19a ./pants --keep-sandboxes=on_failure check tests:kaiko-geometry-tests

to obtain the sandbox. Pants version Using commit 20ac158. OS Tested on Ubuntu 22.04 * * * cc @sureshjoshi pantsbuild/pants
