The Linter failure is unrelated and fixed in #35974

I think each file should be annotated with the distribution which the file belongs to (is installed by). Do we already have a standard style for the annotation?

Yes, that's # sage_setup: distribution = sagemath-bliss, which is currently only used for the few modules depending on optional packages. #35663 is adding many more such directives.

mkoeppe · 2023-07-22T17:58:04Z

For file.py, the annotated distribution would be used as xxx in sage -t --distribution=xxx file.py. Right?

Yes, that's for sure one of the tests to run, but sometimes one also may want to test with extras added to enable more tests.

I think that the future incremental test workflow should run sage -t --distribution=xxx file.py for each modified file.py.

Right.

mkoeppe · 2023-07-22T18:31:05Z

As more files of the sage library get included to newly born distributions, the work practice of a sage developer should change much, albeit there has been little change in the practice up to now. A developer would modify a file such that the file does not break in the distribution it belongs to. If doctests that need other distributions are added, then he needs to test the doctests in another sage install where the additional distributions are available as well.

If the above is right, perhaps we should also update the developer manual to reflect the changing work practice.

Yes, that's a great point. While #35749 is adding a detailed description of how to test in a modularized setting, something has yet to be added to the tutorials that describe the development workflow.

In the worst, a developer would feel like that he/she is expelled from their paradise (where one can import anything from anywhere), after they were scared by the huge flood of optional tags to doctests.

There is certainly a potential for developer frustration after we make failures of the modularized distributions hard errors. This is something to watch out for and mitigate.

kwankyu · 2023-07-22T19:42:54Z

I think each file should be annotated with the distribution which the file belongs to (is installed by). Do we already have a standard style for the annotation?

Yes, that's # sage_setup: distribution = sagemath-bliss, which is currently only used for the few modules depending on optional packages. #35663 is adding many more such directives.

Certainly adding those annotations is a huge task and error-prone, and it is good that there is a one source of truth. That one source of truth should be MANIFEST.in.

Hence it would be nice that we can add the annotations automatically from the manifest files, perhaps as part of the bootstrap. I asked chatGPT how to do that. It answered

python setup.py sdist --manifest-only

But this does not work with me. Its second answer is

python setup.py check --metadata --restructuredtext --strict && python setup.py sdist --formats=zip,gztar

This seems to work. I ran the command in pkgs/sagemath-objects, and got the file pkgs/sagemath-objects/sagemath_objects.egg-info/SOURCES.txt, which list the included files. We may use this file to add the annotations automatically.

Does this make sense?

mkoeppe · 2023-07-22T21:18:10Z

that's # sage_setup: distribution = sagemath-bliss, which is currently only used for the few modules depending on optional packages. #35663 is adding many more such directives.

Certainly adding those annotations is a huge task and error-prone, and it is good that there is a one source of truth. That one source of truth should be MANIFEST.in.

Right now, this is true to some extent, but it's a bit more complicated actually. Some of the setup.py files also do source filtering using the # sage_setup: distribution directives, in addition to the filtering that MANIFEST does.

I'm hoping to unify and simplify this soon; not sure if I really want to keep the MANIFEST mechanism.
Using the # sage_setup: distribution directives as the one source of truth would have the benefit that distributions are guaranteed to be disjoint.

Hence it would be nice that we can add the annotations automatically from the manifest files, perhaps as part of the bootstrap.

This can't be part of the bootstrap because it would need to modify source files that are under version control.

But it would be indeed be very useful as a developer tool when making changes to the contents of the distributions. I'm currently doing this with very primitive tools.

mkoeppe · 2023-07-22T21:22:52Z

I ran the command in pkgs/sagemath-objects, and got the file pkgs/sagemath-objects/sagemath_objects.egg-info/SOURCES.txt, which list the included files. We may use this file to add the annotations automatically.

A better command is ./sage -sh -c '(cd pkgs/sagemath-objects && python3 setup.py egg_info)'

We may use MANIFEST (or something renamed) as a tool to mass-add the file annotations, but use the file annotations as the one source of truth.

From developer's point of view, I think both mechanisms would be useful.

Couldn't we get rid of is_FreeModule on the way?
