The quick summary here is this was not implemented correctly; provides are not fully taken into account in this logic, and making that happen exposes a lot of other flaws in this code that are covered up later on in the dependency resolving process by several other pieces of convoluted and conditional logic. Tests have been adjusted accordingly. Some test EXISTS conditions have been removed as we already know the package is installed locally, and we also are checking the VERSION condition anyway. With these two related revert commits, we do have some changes in test pass/fail results: * upgrade078.py: does not pass, this is due to --recursive getting removed for -U/-S operations after this commit. * sync302.py: the version checks have been disabled, so this test continues to pass but has been scaled back in scope. * sync303.py: now passes, was failing before. * sync304.py: still failing, was failing before. * sync305.py: now passes, was failing before. * sync306.py: still passes, was passing before.
