Description

File ownership not preserved when copying the project inside the container

Regression introduced by #1961

Originally reported by @cdce8p in #1961 (comment)

FYI This change causes a build failure for mypy on manylinux and musllinux with Github actions and ubuntu-latest.
https://github.com/mypyc/mypy_mypyc-wheels/actions/runs/10852483095/job/30118641732#step:4:461

For the build, the mypy repo is first cloned in a previous step and cibuildwheel subsequently run with package-dir: mypy.

The error

fatal: detected dubious ownership in repository at '/project/mypy'

--
I was able to work around it by adding this to linux.before-all:

git config --global --add safe.directory {project}/mypy

The link to the PR: mypyc/mypy_mypyc-wheels#82
