Circular dependency feature not compatible with template's rebel modules

[carmenbianca]

Module

The issue first occurred in coopiteasy/cie-custom#109, which contains custom modules.

Describe the bug

Given:

• Module spp_pos_mustard in https://github.com/coopiteasy/cie-custom/tree/12.0 depends on pos_shift_partner_can_shop.
• Module pos_shift_partner_can_shop exists in our repository https://github.com/carmenbianca/circular-rebel-example.
• Another module other_module in our repository depends on spp_pos_mustard. (edit: spp_pos_mustard is added to test-requirements.txt)
• Module pos_shift_partner_can_shop is a rebel module as per https://github.com/OCA/oca-addons-repo-template.

Then:

• The test for pos_shift_partner_can_shop will pass, correctly installing itself and spp_pos_mustard.
• The test for other_module will fail, failing to install spp_pos_mustard because the dependency pos_shift_partner_can_shop is not met.

See https://github.com/carmenbianca/circular-rebel-example for example GitHub CI runs.

To Reproduce

Affected versions: Any

Described above with example repository.

Expected behavior
I expect pos_shift_partner_can_shop to be pip-installed always so that all modules in test-requirements.txt can be installed without error.

Additional context
N/A

Did this scenario ever work or is it a regression of #58 (at first glance I don't see how it could have worked before) ?

[carmenbianca]

A version of this worked before. Before, as well as having spp_pos_mustard in the test-requirements.txt, pos_shift_partner_can_shop itself would also be in test-requirements.txt. Like so:

git+https://github.com/coopiteasy/cie-custom@12.0#subdirectory=setup/spp_pos_mustard
git+https://github.com/carmenbianca/circular-rebel-example@12.0#subdirectory=setup/pos_shift_partner_can_shop

This would satisfy the Python packaging requirements, and pos_shift_partner_can_shop would later be re-installed from the repository directory. Obviously not a perfect solution. But this stopped working after #58 because the pos_shift_partner_can_shop in test-requirements.txt would not be compatible with the generated pos_shift_partner_can_shop in test-constraints.txt.

The easy/naïve solution, to me, might be to list all local modules in test-constraints.txt. Whether or not excluded/not-included modules are pip-installed doesn't affect the outcome of the test, because they're not installed/initialised on the database. Alternatively, if that is too much installing, one could add an ALWAYS_PIP_INSTALL environment variable which the oca_list_addons_to_test_as_reqs script takes into account, and which would (manually) contain rebel modules with circular dependencies.

@carmenbianca if I understood your issue correctely, it might be fixed by #72
