Bug 531648 – dev-lang/python should not install /usr/lib*/python*/test/

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Patrick Lauer 2014-12-04 10:37:09 UTC]

#  du -h /usr/lib64/python2.7/test/
28M     /usr/lib64/python2.7/test/

 * dev-lang/python-2.7.7
         Total files : 4057
         Total size  : 56.68 MiB


So about half the installed size are the python unit tests that no one uses and which are only relevant at install time.

Not installing (unconditionally, or with use=-test) would halve the installed size for great benefit.

Upstream installs them. If you don't want them, use INSTALL_MASK.

[Comment 2 Mike Gilbert 2014-12-04 17:21:03 UTC]

Hmm... I see other distros package the test suite separately. So I guess a use flag would not be too abnormal here.

[Comment 3 Johan Bergström 2014-12-10 04:37:52 UTC]

I'd also like to see test suites go away. This should be documented somewhere since its pretty common for test folders to be installed for setuptools/pip packages as well.

Agreed. If we are going to remove tests, we should come up with a consistent policy for it. This would include:

- A consistently named use flag
- A code snippet on the wiki

Personally, I would prefer to keep installing tests unconditionally, but if I'm out-voted it is no great bother to me.

I'd say this is a case for INSTALL_MASK.

A note on implementing this for dev-lang/python:

The test.support module gets used in the test suites for lib2to3, idlelib, and distutils. These are installed outside of the python/test/ directory.

Also, it looks like some the tests of some third-party packages import test.support. For example:

site-packages/simplejson/tests/test_tool.py:        from test.support import strip_python_stderr
site-packages/bsddb3/tests/test_all.py:    from test import test_support


So, we would probably need to install the test.support module to avoid breaking src_test in a few python-related ebuilds.

test directory is only for people who do testing. People who do testing, have `test` USE-flag set. So I think

python:
```
use test || rm -rf ....
```

and 

dev-python/simplejson:
```
PYTHON_REQ_USE="test="
```

would solve this case.
