Jie Yu created MESOS-5807:
-----------------------------
Summary: Support job_object in subprocess on Windows.
Key: MESOS-5807
URL: https://issues.apache.org/jira/browse/MESOS-5807
Project: Mesos
Issue Type: Improvement
Reporter: Jie Yu
Currently, in command executor, we use different code path for posix and
windows:
{noformat}
#ifndef __WINDOWS__
pid = launchTaskPosix(
command,
launcherDir,
user,
rootfs,
sandboxDirectory,
workingDirectory);
#else
// A Windows process is started using the `CREATE_SUSPENDED` flag
// and is part of a job object. While the process handle is kept
// open the reap function will work.
PROCESS_INFORMATION processInformation = launchTaskWindows(
command,
rootfs);
pid = processInformation.dwProcessId;
::ResumeThread(processInformation.hThread);
CloseHandle(processInformation.hThread);
processHandle = processInformation.hProcess;
#endif
{noformat}
During a recent refactor (MESOS-5753), for the posix path, command executor
reused `mesos-containerizer launch` helper to launch user tasks.
If we were to be able to support job_object in Subprocess, we can get rid of
this divergence in command executor. This also allow us to support custom
executors on Windows.
