[issue17732] distutils.cfg Can Break venv
Vinay Sajip added the comment: This looks to me as if it will need a patch in distutils. Unlike virtualenv, which contains a patched copy of distutils (and hence allows having a .cfg adjacent to it), pyvenv does not create patched modules in the venv. It does not make sense to change this behaviour. The correct solution would appear to be for distutils to ignore certain configuration options (install-lib, but also equivalent options for headers and scripts) when running in a venv. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17732 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17732] distutils.cfg Can Break venv
Vinay Sajip added the comment: On second thought, there is probably no good reason to ignore the build-* settings. I was just about to mention this. I'm not an expert on distutils internals and whether this is the best way to accomplish what's needed, but the approach seems reasonable to me. Why the empty list and the extend, though? Why not something like the following? if sys.prefix == sys.base_prefix: # not in venv ignore_options = [] else: # in venv ignore_options = ['install-base', ...] My other comments on the patch are generic, i.e. you need to look at the tests and docs, too. Anyway, thanks for the effort you've spent to come up with a patch.

[issue17732] distutils.cfg Can Break venv
Nick Sloan added the comment: My thought was that perhaps there will be other circumstances where we may want to ignore options in the future. The idea was that by providing an ignore_options list that can be extended, multiple conditions with different sets of options can be stacked together easily. I was thinking a set might actually be an even better choice than a list. Would love feedback on this approach. Am I over-designing for an unlikely case? I'm happy to use Vinay's suggestion if we don't think it is worth it to consider possible future conflicts with distutils.cfg options. If there is any reason a set would be worse to use, let me know, otherwise my next patch will use a set rather than a list. Another question: should I be checking which config file these come from, or ignoring all occurrences of these options? Seems like setup.cfg at the very least shouldn't have any restrictions. Possibly ~/.pydistutils.cfg too. I'll review tests to see if this necessitates any changes, add a new test that covers this, and I'll make a note in the docs. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17732 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17732] distutils.cfg Can Break venv
New submission from Nick Sloan: When distutils.cfg defines an install-lib, it will be used within virtual environments created using venv as well, which makes it impossible to install things with setup.py or similar. Steps to reproduce: Create a distutils.cfg file and set a value for install-lib. Create a virtual environment: $pyvenv myvenv Activate that environment: $source myvenv/bin/activate Attempt to install something: $python distribute_setup.py It will attempt to install in the lib-install directory, and should fail with an error that the directory is not on the python path. This issue affects python3 from the mac homebrew project, which bundles a distutil.cfg, thus breaking pyvenv by default. -- assignee: eric.araujo components: Distutils messages: 186942 nosy: eric.araujo, nicksloan, tarek priority: normal severity: normal status: open title: distutils.cfg Can Break venv type: behavior versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17732 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Nick Sloan added the comment: It looks like virtualenv includes an empty distutils.cfg at myvirtualenv/lib/python3.3/distutils/distutils.cfg. Most of myvirtualenv/lib/python3.3 is just symlinked to the base python version, but myvirtualenv/lib/python3.3/distutils/ is not, and I bet this is exactly why. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17732 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
