No content is built in downstream Fedora CI

[jan-cerny]

When a pull request is created in Fedora Pagure packit tests are automatically triggered. The /static-checks/rpmbuild-ctest fails because no content is built as a part of the test.

Example Fedora PR: https://src.fedoraproject.org/rpms/scap-security-guide/pull-request/81

The /static-checks/rpmbuild-ctest first tries to build scap-security-guide but it doesn't build any content for any product, all products are disabled, but it tries to build a non-existent RHEL 45 product. Notice the -DSSG_PRODUCT_RHEL45:BOOL=ON in the cmake command.

2026-09-03 16:15:04 test.py:17: lib.util.content.build_content:241: running: cmake ../ -DCMAKE_BUILD_TYPE:STRING=Release -DSSG_CENTOS_DERIVATIVES_ENABLED:BOOL=OFF -DSSG_PRODUCT_DEFAULT:BOOL=OFF -DSSG_PRODUCT_RHEL45:BOOL=ON -DSSG_SCE_ENABLED:BOOL=ON -DSSG_BASH_SCRIPTS_ENABLED:BOOL=OFF -DSSG_BUILD_DISA_DELTA_FILES:BOOL=OFF -DSSG_SEPARATE_SCAP_FILES_ENABLED:BOOL=OFF -DSSG_ANSIBLE_PLAYBOOKS_PER_RULE_ENABLED:BOOL=ON

Then, the test attempts to run CTest tests, but since there was no content built, there are 2 problems:

1. the set of the CTest tests is very limited
2. some tests fail because lack of testable content

The problem 2 manifests as this traceback:

Traceback (most recent call last):
  File "/var/tmp/tmp4vhg0ciq/BUILD/scap-security-guide-0.1.82-build/scap-security-guide-0.1.82/tests/test_profile_variables.py", line 261, in <module>
    sys.exit(main())

    raise RuntimeError("No built products found (no rule_variable_mapping.json files)")
RuntimeError: No built products found (no rule_variable_mapping.json files)

We need to modify how the content is built in the test in static-checks/rpmbuild-ctest/test.py, perhaps add support for Fedora to the build_content function in lib/util/content.py.

[comps]

The test just calls the library function for building content, which uses versions.rhel.major:

contest/lib/util/content.py

Line 212 in fa06d08

f'SSG_PRODUCT_RHEL{versions.rhel.major}:BOOL': 'ON',

And that should be auto-detected from /etc/os-release by

contest/lib/versions.py

Lines 44 to 47 in fa06d08

	@staticmethod
	def _parse_version(version):
	major, _, minor = str(version).partition('.')
	return (int(major), int(minor) if minor else None)

That's because Contest was never meant to run on Fedora, and we still don't officially support it to avoid increasing the maintenance scope.

However maybe we can have an early fail on versions that double-checks whether the ID= is rhel or something like that and hard-fails with something like "Fedora is unsupported", rather than silently parsing major version as 45 for Fedora 45.
