[OpenBSD] Problem with the *Process* class

[mwallnoefer]

Platform

• 6.6
• 5.4.3
• 2.7.16

Bug description
I cannot get the meta infomation about the processes. E.g. the following one triggered by _pid_0_exists() in (_psbsd.py):

$ python2.7 -c "import psutil; psutil.Process(0)"
  File "/usr/local/lib/python2.7/site-packages/psutil/_psbsd.py", line 554, in oneshot
    ret = cext.proc_oneshot_info(self.pid)
SystemError: NULL object passed to Py_BuildValue

And for PID 1:

$ python2.7 -c "import psutil; psutil.Process(1)" 
Segmentation fault (core dumped) 

Test results

[unfortunately I have no line numbers]

$ python2.7 -m psutil.tests 
Segmentation fault 
$ gdb --args python2.7 -m psutil.tests

Try with latest psutil version

[mwallnoefer]

Yeah, in the meantime I have seen that there has been done some patching on _psbsd.py which likely addresses this (https://github.com/giampaolo/psutil/commits/master/psutil/_psbsd.py).

I will see how to get a more recent version of psutil on OpenBSD 6.6. Thanks!
