            Bug ID: 6887
           Summary: Many tests failing with Python 3.12 (distutils issue?)
           Product: Mercurial
           Version: 6.8
          Hardware: PC
                OS: Linux
            Status: UNCONFIRMED
          Severity: bug
          Priority: wish
         Component: Mercurial
          Assignee: bugzilla at mercurial-scm.org
          Reporter: kwalkq.mercurial-bugzilla at pacien.net
                CC: mercurial-devel at mercurial-scm.org
    Python Version: ---

Running the test suite of hg 6.8 with Python 3.12 results in many failed tests:

        # Ran 782 tests, 242 skipped, 143 failed.
        python hash seed: 0

Here's the full log of all tests runs for NixOS:

Looking over the test failures, I speculate that there is some issue with
output filtering, and in particular "has" checks from hghave.py not being
selected correctly.

Indeed, hghave.py appears to be importing the "distutils" package,
which has been removed from the Python 3.12 distribution:

        +  Traceback (most recent call last):
        +    File "/build/mercurial-6.8/tests/hghave", line 8, in <module>
        +      import hghave
        +    File "/build/mercurial-6.8/tests/hghave.py", line 1, in <module>
        +      import distutils.version
        +  ModuleNotFoundError: No module named 'distutils'
        +  [1]
