3.8.0: pytest is failing in ::project unit

[kloczek]

I'm trying to package your module as an rpm package. So I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
• install .whl file in </install/prefix>
• run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Here is pytest output:

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-jaraco-text-3.8.0-2.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-jaraco-text-3.8.0-2.fc35.x86_64/usr/lib/python3.8/site-packages

I'm going add that unit in my build procedure to --deselet list.

[jaraco]

It appears that in your environment, when pytest-checkdocs invokes:

pep517.meta.load('.')

Which results in an exception. Unfortunately, the exception is unclear from the output.

It fails to create a build environment in order to compute the metadata.

I'd suggest to try to replicate the error using pep517 only.

If you can create a Dockerfile that replicates the issue, I can probably inspect more deeply.

I don't believe this project is doing anything special compared to other projects I maintain, so I'm surprised the issue is only happening with this project in particular.

To work around the issue, you can probably disable the checkdocs plugin by passing -p no:checkdocs to pytest.

Please have look one more time on top of this ticket.
I'm usin pep517 build procedure.

If you can create a Dockerfile that replicates the issue, I can probably inspect more deeply.

I'm not using docker and ano go related software as it popents seriouse security risk (please look on rate of CVEs in golang; docker implemeted in python is no longer maintained).

To work around the issue, you can probably disable the checkdocs plugin by passing -p no:checkdocs to pytest.

Is ti not easier to fix that issue?

[jaraco]

The problem is that I don't have a way to replicate the issue. Tests pass for me. Moreover, this project is using the same technique of pytest-checkdocs. I can't think of any reason why this project should have trouble but the dozens of others I maintain do not.

[jaraco]

I did try replicating the issue by using pip to install packages to system Python 3.10 on Ubuntu 20.04, but the tests still run. I need help replicating the issue. If not a dockerfile, can you provide a script that replicates the issue on a clean OS image?

[kloczek]

This issue is possible to solve by:

• fixing ::project unit
• add pytest settings testpaths variable to force pytest to scan only in exact directory/directories

[jaraco]

The ::project unit is the test for pytest-checkdocs. It's part of the test suite and ensures that the README renders properly. The test works fine, but it relies on being able to resolve the metadata, which requires downloading and installing build dependencies.

pytest-checkdocs was recently rewritten to use build instead of pep517 (jaraco/pytest-checkdocs#17). This issue is the same as jaraco/pytest-checkdocs#19, whose root cause is tracked in pypa/build#556.

Someone needs to implement a mechanism for offline builds to support building metadata.
