Research direction

Start with setup.py and inspect the listed distutils references under src/debugpy/_vendored/pydevd, including its setup and build files and the version/inputhook modules. Check the affected paths under Python 3.12 and determine which references are active runtime or build dependencies. Done means the relevant distutils uses no longer block supported setup or execution paths.

Description

needs repro

setup.py currently falls back to distutils if versioneer does not provide the required "build" command:
https://github.com/microsoft/debugpy/blob/fb6158a059bcc6a0391eb0f670d5885d664c102d/setup.py#L62-L65
But distutils no longer exists in Python 3.12, so this code needs to be updated: either versioneer always provides this, in which case the try/except is unnecessary, or it doesn't, in which case the distutils call needs to be replaced.

There are also calls to distutils in several places in the vendored pydevd, some of which may be important to fix; an rgrep gives these occurrences:

src/debugpy/_vendored/pydevd/setup.py:from distutils.extension import Extension
src/debugpy/_vendored/pydevd/_pydevd_frame_eval/pydevd_frame_evaluator.c:    "distutils": {
src/debugpy/_vendored/pydevd/pydev_ipython/inputhook.py:        from distutils.version import LooseVersion as V
src/debugpy/_vendored/pydevd/pydev_ipython/version.py:from distutils.version import LooseVersion
src/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_cython.c:    "distutils": {
src/debugpy/_vendored/pydevd/setup_pydevd_cython.py:        from distutils.extension import Extension
src/debugpy/_vendored/pydevd/build_tools/build.py:                    from distutils import msvc9compiler
