Some tests from IPython/extensions/tests/test_deduperreload.py fail when using 32-bit Python #15107
Description
When I try to run IPython’s tests on NixOS 25.05 with a 32-bit version of Python, these tests fail:
-
IPython/extensions/tests/test_deduperreload.py::DecoratorPatchingSuite::test_function_decorator_from_other_module -
IPython/extensions/tests/test_deduperreload.py::DecoratorPatchingSuite::test_function_decorators -
IPython/extensions/tests/test_deduperreload.py::DecoratorPatchingSuite::test_method_decorator
Steps to reproduce
-
Make sure that you have a copy of IPython’s Git repository on your system. Make sure that the path to your copy of IPython’s Git repository does not contain spaces, or else you will run into this other bug.
-
Open a terminal.
-
Make sure that you have a 32-bit version of Python. If you use the Nix package manager, then you can make sure that you have the exact same version of Python that I used to reproduce this bug by doing the following:
-
Create a file named
shell-for-working-on-ipython.nixthat contains the following Nix expression:# This file is dedicated to the public domain using 🅭🄍1.0: # <https://creativecommons.org/publicdomain/zero/1.0>. let nixpkgsCommit = "2b0d2b456e4e8452cf1c16d00118d145f31160f9"; nixpkgsDirectory = builtins.fetchTarball { url = "https://github.com/NixOS/nixpkgs/archive/${nixpkgsCommit}.tar.gz"; sha256 = "1c04l0yx2g9v5dslbxdy25x8pvja6mxyi6xqpmgzw61ry5yxbggv"; }; pkgs = import nixpkgsDirectory { }; in pkgs.pkgsi686Linux.mkShellNoCC { name = "shell-for-working-on-ipython"; packages = [ pkgs.pkgsi686Linux.python314 ]; }
-
Activate that Nix shell by running the following command:
nix-shell <path to shell-for-working-on-ipython.nix>
-
-
Create a new virtual environment by running this command:
python -m venv <path to where you want the venv to be created>
-
Activate the virtual environment that you just created. (See this section of the Python documentation).
-
(Recommended) Update pip by running this command:
python -m pip install --upgrade pip
-
Change directory to the root of your local copy of IPython’s Git repository by doing one of the following:
-
If your terminal is using the Windows Command Shell, then run this command:
CD /D <path to repo>
-
Otherwise, run this command:
cd <path to repo>
-
-
(Optional) Switch to a Git commit that is known to have this issue by running this command:
git switch --detach 11e1f400eecbfa12bbf55cdfff758a256d41d34e
-
Install a development version of IPython by running this command:
pip install -e '.[test]' -
Run IPython’s tests by running this command:
pytest
