Test failures when path to IPython source code contains spaces #15100
Description
When I try to run IPython’s tests on NixOS 25.05, these tests fail:
tests/test_interactiveshell.py::ExitCodeChecks::test_exit_code_signaltests/test_interactiveshell.py::TestSystemRaw::test_exit_code_signaltests/test_interactiveshell.py::TestSystemPipedExitCode::test_exit_code_signal
EDIT: It turns out that those failures happen only if you store IPython’s source code in a directory that has at least one space in its path.
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 contains at least one space.
-
Open a terminal.
-
Make sure that you have the
pythoncommand. 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 = "09eb77e94fa25202af8f3e81ddc7353d9970ac1b"; nixpkgsDirectory = builtins.fetchTarball { url = "https://github.com/NixOS/nixpkgs/archive/${nixpkgsCommit}.tar.gz"; sha256 = "02hdh4r0cc5h78cmymndb8clfhkn6phbrkrv6s8kvyfspqwzj84r"; }; pkgs = import nixpkgsDirectory { }; in pkgs.mkShellNoCC { name = "shell-for-working-on-ipython"; packages = [ pkgs.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 f63b2acb992e0e88619f4486bc67620f9f50fe50
-
Install a development version of IPython by running this command:
pip install -e '.[test]' -
Run IPython’s tests by running this command:
pytest
