Summary

• OS: OpenBSD
• Bug fix: yes
• Type: core

Description

See failure:

====================================================================== ERROR: psutil.tests.test_process.TestProcess.test_zombie_process ---------------------------------------------------------------------- Traceback (most recent call last):
  File "/vagrant/psutil/psutil/_psbsd.py", line 560, in wrapper
    return fun(self, *args, **kwargs)
  File "/vagrant/psutil/psutil/_psbsd.py", line 862, in open_files
    rawlist = cext.proc_open_files(self.pid)
ProcessLookupError: [Errno 3] No such process

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/vagrant/psutil/psutil/tests/test_process.py", line 1312, in test_zombie_process
    zproc.as_dict()
  File "/vagrant/psutil/psutil/__init__.py", line 528, in as_dict
    ret = meth()

  File "/vagrant/psutil/psutil/_psbsd.py", line 565, in wrapper
    raise NoSuchProcess(self.pid, self._name)
psutil.NoSuchProcess: process no longer exists (pid=67013)

This happens because OpenBSD is the only BSD defining 2 codes for zombie processes:

        # According to /usr/include/sys/proc.h SZOMB is unused.
        # test_zombie_process() shows that SDEAD is the right
        # equivalent. Also it appears there's no equivalent of
        # psutil.STATUS_DEAD. SDEAD really means STATUS_ZOMBIE.
        # cext.SZOMB: _common.STATUS_ZOMBIE,
        cext.SDEAD: _common.STATUS_ZOMBIE,
        cext.SZOMB: _common.STATUS_ZOMBIE,
