test_memory_leaks.TestProcessObjectLeaksZombie.test_ionice_set() fails #539

Closed Arfrever closed 10 years ago

Arfrever commented 10 years ago

test_memory_leaks.TestProcessObjectLeaksZombie.test_ionice_set() fails. This problem seems to occur only with Python 3.4. I use Linux 3.16.3.

$ PYTHONPATH="build/lib.linux-x86_64-3.4" python3.4 test/test_memory_leaks.py

Does it fail from time to time or every time? I'm asking because test_memory_leaks.py script is not fully reliable: it sometimes produces false positives.

Arfrever commented 10 years ago

The failure occurs every time when running test suite of psutil by Portage (Gentoo package manager).

This test failure no longer occurs for me.
