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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
