[RPM Packaging] The format used in 'pyproject.toml' for 'packages' key does not seem to fit standards for RPM build

Hello tappy team!

I am working in an organization that is using the TAP format, and in this goal we are building this tappy project as a '.rpm' package.
However since, the last release (v3.2) and especially since the modification of your build method, we are not able to package directly this project.

The good new is that I've found the cause of this issue.

Indeed, in your pyproject.toml file, there is this section:

[tool.hatch.build.targets.wheel]
sources = ["src"]
packages = ["tap"]

And after some tests, it seems that the standard RPM tools[1] used to build a rpm package from a python repository does not always recognize this syntax. Simply changing this section to the following fixes the problem in my case.

[tool.hatch.build.targets.wheel]
sources = ["src"]
packages = ["src/tap"]

I guess it depends on the version of hatchling used, but since it is not explicitly set in your project...
For information the hatchling version I'm using is 1.27.0.

Best regards and have a beautiful day!
Armand.

PS: this issue is also valid for pytest-tap repo!

Thanks for the report. Do you have confidence in the fix? There is an open PR for pytest-tap with a similar fix, but it doesn't work and leaves the built package with no files in it (python-tap/pytest-tap#105). I'm open to a fix, but it has to be something that work.

BTW, I'm a solo maintainer with drive-by contributors and I'm not actively working on the project lately. The odds of getting this fixed go up greatly with a PR. 😁 The test suite runs against tox, so it should be pretty clear if the fix works from a CI run. I won't have time to work on this this week.

Hi ! I have no problem to open a PR, I will try to do so in the next day. I usually open an issue before because sometime the maintainers of repositories would rather have an issue first and then a PR if they agree.

I will also have a look on the PR you mentioned. Thanks!

So I have a bit of time today and I've started investigating. Let me write here my first observations.

I've forked the project, created the virtual environment locally on my laptop, installed tox and uv and let's go!

For each case I will also give the version of hatchling used.
For the "modified file case", the modification I am doing is the following:

diff --git a/pyproject.toml b/pyproject.toml
index b0d617c..34118d9 100644
--- a/pyproject.toml
+++ b/pyproject.toml
@@ -58,7 +58,7 @@ sources = ["src"]
 
 [tool.hatch.build.targets.wheel]
 sources = ["src"]
-packages = ["tap"]
+packages = ["src/tap"]
 
 [tool.pytest.ini_options]
 pythonpath = [".", "src"]

I will use two build commands: uv build (it is the one used here) and python3 -m pip wheel . (the one used in the rpm packaging environment and probably for Debian packaging as well).

Case 1: original `pyproject.toml` file + build command line: `uv build`

Results: I correctly have all the python files in the wheel.

Conclusion

So... there is something weird between how uv is building and how python3 -m pip wheel is building. What could be great to find is how we could conciliate both.

The positive point from this experiment is that it shows that the problem does not come from the hatchling version.

Solution found! See your PR #166 😉
