This is a huge version jump, which unfortunately changes the API (Process.{,set_}{,io}nice) and adds a warning for it. Here are two reproducers:

python -c "import os;import psutil; p = psutil.Process(os.getpid()); p.set_nice(18); p.set_ionice(psutil.IOPRIO_CLASS_BE, 6)"

• with 0.6.1-1, it gets no error/no warning
• with 2.2.1-1, it gets:

-c:1: DeprecationWarning: set_nice() is deprecated; use nice() instead -c:1: DeprecationWarning: set_ionice() is deprecated; use ionice() instead

python -c "import os;import psutil; p = psutil.Process(os.getpid()); p.nice(18); p.ionice(psutil.IOPRIO_CLASS_BE, 6)"

• with 2.2.1-1, it gets no warning/error
• with 0.6.1-1, it gets:

-c:1: DeprecationWarning: this property is deprecated; use Process.get_nice() method instead Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: 'int' object is not callable

karma: -1

Breaks a lot of comatability and I think the bug could be addressed with a lesser version.

Perhaps you could share those findings in the attached bug?

I was just going off the suggestion there. In the mean time I'll unpush this until we sort it out.
