-------------------------------------------
Summary: Mesos attempts to open handle for the system idle process
Key: MESOS-7988
URL: https://issues.apache.org/jira/browse/MESOS-7988
Project: Mesos
Issue Type: Bug
Components: stout
Environment: Windows 10
Reporter: Andrew Schwartzmeyer
Assignee: Andrew Schwartzmeyer
While running {{mesos-tests}} under Application Verifier, I found that we were
inadvertently attempting to get a handle for the System Idle Process. This is
not permitted by the OS, and so the {{OpenProcess}} system call was failing. I
further found that we were incorrectly checking the failure condition of
{{OpenProcess}}. We were attempting to open this handle when opening handles
for all PIDs returned by {{os::pids}}, and the Windows API {{EnumProcess}}
includes PID 0 (System Idle Process). As this PID is not useful, we can safely
remove it from the {{os::pids}} API. Attempting to do _anything_ with PID 0
will likely result in failure, as it is a special process on Windows, and so we
can help to prevent these errors by filtering out PID 0.
