[New-bugs-announce] [issue45783] test_freeze fails if a file is removed

[Petr Viktorin]

New submission from Petr Viktorin <encukou at gmail.com>:

In Fedora, we remove the bundled wheels; pip & co. are supplied (and kept updated) by the system. I believe this is good practice.

However, removing any file from the CPython source checkout makes test_freeze fail:

Traceback (most recent call last):
  File "/builddir/build/BUILD/Python-3.11.0a2/Lib/test/test_tools/test_freeze.py", line 25, in test_freeze_simple_script
    outdir, scriptfile, python = helper.prepare(script)
                                 ^^^^^^^^^^^^^^^^^^^^^^

It looks like this test is recreating uncommited modifications, is it OK to change it to support deletions as well?
Also, `git status --porcelain` should be used to get the output in a stable format.
