Issue 34668: test_resource fails if test has CAP_SYS_RESOURCE but isn't root (original) (raw)

test_prlimit tries to test that raising the hardlimit of an unprivileged process. It tries to raise the hardlimit of pid 1, which usually raises a PermissionError. However, if the tests are privileged, this test can't work. The test tries to avoid this by only running the test if os.geteuid() != 0. However, there are other cases. For example, if the test process isn't root but has CAP_SYS_RESOURCE. While we could check for these other cases, I think we should just delete this test. There's no special logic in the prlimit implementation for handling permission errors, so it's not adding much value.
