Strange PID 0 exception behavior on Windows #22

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

>>> psutil.Process(0).kill()
>>> psutil.Process(2408).name
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python26\Lib\site-packages\psutil\psutil.py", line 54, in __init__
    if not pid_exists(pid):
  File "C:\Python26\Lib\site-packages\psutil\psutil.py", line 149, in
pid_exists

    return _platform_impl.pid_exists(pid)
  File "C:\Python26\Lib\site-packages\psutil\_psmswindows.py", line 29, in
pid_e
xists
    return pid in _psutil_mswindows.get_pid_list()
WindowsError: [Error 87] Parametro non corretto
>>>
>>> psutil.Process(2408).name
'xchat.exe'
>>>

It seems that psutil.Process(0).kill() fails internally and that its
exception is "cached" somehow and raised when we attempt to fetch
information from another process.

Fixed in r148 - kill_process() was returning 0 instead of NULL so the exception 
was
only being set and not raised like it should have been.
