ansible: replace DO debian9-x64-1 with debian12-x64-1

Draft because the Python setup changed from previous versions and I don't know how to install tap2junit with it.

  cmd: [
    '/usr/bin/python3',
    '-m',
    'pip.__main__',
    'install',
    'tap2junit==0.1.6'
  ],

:stderr: error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.

    See /usr/share/doc/python3.11/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

It looks like we want to use pipx ? tap2junit is used as a CLI app, not a library.

/cc @cclauss

[cclauss]

usr/bin/env python3 -m pip install tap2junit==0.1.6

The .__main__ thing seems like something to delete.

Let's not depend on pipx.

[targos]

/usr/bin/env python3 -m pip install tap2junit==0.1.6 prints the same error.

Would it be ok to install with --break-system-packages ?

[targos]

With the last commit, tap2junit is installed in a virtualenv:

# ls /home/iojs/venv/bin
activate      activate.fish  activate.ps1      pip	 pip3	  python   python3.11  wheel	   wheel3
activate.csh  activate.nu    activate_this.py  pip-3.11  pip3.11  python3  tap2junit   wheel-3.11  wheel3.11

Now what's the best way to have it activated when jenkins runs?

[targos]

/home/iojs/venv/bin/tap2junit is a Python script with hashbang: #!/home/iojs/venv/bin/python

[targos]

Updated to use venv instead of virtualenv. Question above is still open.

[targos]

I can think of solutions but can't say if they're good:

• Add the location of the venv/bin directory to the PATH in https://github.com/nodejs/build/blob/main/ansible/roles/jenkins-worker/templates/systemd.service.j2#L21
• Add a step that creates a symlink of tap2junit in /usr/bin or /usr/local/bin
• Source venv/bin/activate if it exists before starting Jenkins

[targos]

/cc @nodejs/build

[cclauss]

• Add the location of the venv/bin directory to the PATH

[targos]

Subsidiary question: at the start or the end of the PATH?

Another question: the current setup installs the venv as root, so maybe we want to do it in another place than /home/iojs, or we want to install it as the iojs user?

[cclauss]

https://packages.debian.org/stable/pipx also brings along python3-venv and friends.

[targos]

Running with pipx sounds much more involved because we would need to do it conditionally until all CI hosts are setup with it.
