PEP 632: Remove the distutils package (Python 3.12) #92584

vstinner · 2022-05-09T22:42:26Z

The distutils module was deprecated in Python 3.10 and is scheduled for removal in Python 3.12.

Right now, Python still uses distutils for different purpose:

Build C extensions which can not be built by Makefile yet. Python 3.11 can build way more C extensions with Makefile than Python 3.10.
peg_generator uses distutils to build C extensions.
test_cppext uses distutils to check that the Python C API can be used in C++.
Tools/c-analyzer/ uses distutils to get a C preprocessor.

Until Python can be built and used without distutils, I propose to first rename the distutils package to _distutils: rename th Lib/distutils/ directory to Lib/_distutils/.

Right now, test_venv fails without distutils, because pip fails on importing the distutils module in pip/_internal/locations/_distutils.py: https://github.com/pypa/pip/blob/cb24fb4052ca8ab8009866b0de61980c81a7e13c/src/pip/_internal/locations/_distutils.py#L9-L12

I created the PR #92585 which renames distutils to _distutils.

Right now, test_venv fails without distutils, because pip fails on importing the distutils module in pip/_internal/locations/_distutils.py

I reported this issue to pip: pypa/pip#11103

vstinner · 2022-05-09T22:53:16Z

The distutils package was deprecated by the issue #85454.

vstinner · 2022-05-10T00:09:23Z

PEP 632 "Deprecate distutils module": https://peps.python.org/pep-0632/

FFY00 · 2022-05-10T00:40:08Z

That seems like a good plan. Thanks.

jaraco · 2022-05-10T11:16:59Z

My fear with renaming it is that it lingers indefinitely, and diverging in subtle ways from pypa/distutils. Why not address the dependencies and fully remove the functionality?

Regardless, I agree renaming is preferable to not removing the module at all.

vstinner · 2022-05-10T11:20:15Z

Why not address the dependencies and fully remove the functionality?

Someone has to modify Python to no longer depend on distutils. The issue description lists code using it. It doesn't seem trivial.

FFY00 · 2022-05-10T14:01:58Z

Would it be reasonable to keep it around in the repo while we don't drop the dependency but not ship it as part of Python installations?

vstinner · 2022-05-10T15:23:24Z

Would it be reasonable to keep it around in the repo while we don't drop the dependency but not ship it as part of Python installations?

With my PR, the Lib/_distutils/ directory is not installed by make install.

jkloth · 2022-05-10T15:56:16Z

Do note that we have buildbots that run from an installed Python. The tests would need to also be modified to fail gracefully
(or skip) when _distutils is not available.

vstinner · 2022-05-10T16:01:16Z

I propose skipping tests relying on _distutils if _distutils is not available.

vstinner · 2022-05-10T20:53:26Z

I wrote two PRs to avoid the deprecated distutils module in two tests:

gh-92584: test_cppext uses setuptools #92639: test_cppext uses setuptools
gh-92584: test_decimal uses shutil.which() #92640: test_decimal uses shutil.which() -- IMO an uncontroversial change

test_decimal now uses shutil.which() rather than deprecated distutils.spawn.find_executable().

Rewrite test_cppext to run in a virtual environment and to build the C++ extension with setuptools rather than distutils.

AbhigyanBose · 2022-05-15T12:44:47Z

Hi @vstinner

I think #92639 is causing a test failure, details here #92820

PS: Commented here as I thought those changes are related to this PEP.

encukou · 2022-06-23T12:53:13Z

Marking as 3.12.0a1 release blocker. We want to have public-facing distutils gone in the first alpha, to have as much time as possible to deal with the fallout.

tiran · 2022-07-07T12:37:01Z

Actually we can get rid of distutils entirely. I have a working PR that gets rid of our setup.py and builds all extension modules with configure and make.

pradyunsg · 2022-07-08T16:19:27Z

For the curious, the PR that @tiran is refering to is #94474

`make test_cppmods` compiles C++ test extension modules.
