`python2 -S` is broken #2025

Closed navytux closed 1 year ago

navytux commented 3 years ago

Issue

Hello up there. I've discovered that python -S is broken in virtualenv created for python2. It works ok for python3. Please find details below:

kirr@deco:~/src/tools/py/pypa/virtualenv$ . 1.venv/bin/activate
(1.venv) kirr@deco:~/src/tools/py/pypa/virtualenv$ python
Python 2.7.18 (default, Apr 20 2020, 20:30:41) 
[GCC 9.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
(1.venv) kirr@deco:~/src/tools/py/pypa/virtualenv$ python -S
Python 2.7.18 (default, Apr 20 2020, 20:30:41) 
[GCC 9.3.0] on linux2
>>> import os
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/kirr/src/tools/py/pypa/virtualenv/1.venv/lib/python2.7/os.py", line 49, in <module>
    import posixpath as path
ImportError: No module named posixpath

Thanks beforehand, Kirill

Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

This works for me on the macOs. Do you have a repro via a Docker image?

navytux commented 3 years ago

Yes, I can reproduces that in debian docker image e.g. via docker run --name test -it debian:

If my bisect is correct, the regression comes from 9569493453a39d63064ed7c20653987ba15c99e5

If my bisect is correct, the regression comes from 9569493

The reproduction steps were about using python3 to create a python2 virtualenv. Before 9569493, the created 1.venv/bin/python is a symlink to system python2 executable and python -S -c "import os" works fine. After, it is a copy.

But it seems the symlinking was accidental, the intention was to copy executable for python2. In https://github.com/pypa/virtualenv/commit/9569493453a39d63064ed7c20653987ba15c99e5#diff-e87e31e7905a55448cbbeda24d36cc6ae4eb6cca03ee0b31224872c53c6baa26R53-R55 there is a change to check if the target python is python2 instead of checking if the python running virtualenv is python2. When creating a python2 environment using python2, python -S -c "import os" does not work before or after 9569493.

So 9569493 just fixes an inconsistency when running python3 and does not introduce a regression.

We no longer support python 2.
