Subject: test: optionally run test venvs with system site-packages
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=ae6bc8220b7b7a229d32064ea5dc2f3d88badbae;p=ceph.git

test: optionally run test venvs with system site-packages

Add a CEPH_PYTHON_SYSTEM_SITE switch (off by default). When set:

  - setup-virtualenv.sh builds its venv with --system-site-packages;
  - run_tox.sh exports VIRTUALENV_SYSTEM_SITE_PACKAGES=true for tox's venvs.

This lets distro packages satisfy test dependencies instead of pip building
them from sdist, which helps where prebuilt wheels are missing (e.g. scipy and
numpy on riscv64) by avoiding a slow rebuild when the RPMs are installed.
