I wonder if we need such cases which will create stapusr, stapdev, and then test as these users.Hmm. I see what you are thinking, but I'm not sure that's a great use of your time. We do test those privileges with the tests in the systemtap.unprivileged directory. Creating users from the test suite is problematic - I'm not sure admins would be too happy with us and the commands to create users can vary from distro to distro.BTW, I have no more cases.Here's one idea. I've been working with the dwarfless-kprobe (kprobe.function and module.kprobe.function probes), and I found that the module.kprobe stuff wasn't tested well. I fixed the modules_out_of_tree.exp and kmodule.exp tests to test the dwarfless-kprobe module support in the same manner as the dwarf-based kprobe module suport (module.function probes). I'd find it helpful if you could make a pass through the other tests and see if there are any I missed that need some kprobe.module tests added.
I will follow the work when I have time. There are several things I have to do this month.
Assuming you want to keep working on the testsuite, here's one PR to look at: <https://sourceware.org/bugzilla/show_bug.cgi?id=13874> Here's another idea I've been thinking about. One problem we've got right now is in comparing the results of one test run against another. We've got several tests that seem to fail at random times and if you run it again it will pass. I never seem to find the time to debug those issues. A good place to start would be to run the testsuite several times in a row and see which tests results aren't consistent. After getting a list of odd tests, then we could start debugging the issues.
-- Thanks Zhou
