---------------------------------
Summary: Port kill policy test helper on Windows
Key: MESOS-8168
URL: https://issues.apache.org/jira/browse/MESOS-8168
Project: Mesos
Issue Type: Task
Reporter: Qian Zhang
Assignee: Andrew Schwartzmeyer
Priority: Normal
Kill policy test helper ({{src/tests/kill_policy_test_helper.cpp}}) blocks
until it receives a {{SIGTERM}}, then sleeps for a configurable amount of time
before finally returning 0, so it actually implements graceful shutdown.
But currently kill policy test helper only calls Linux specific functions to
set up signal handler, so it can not be compiled on Windows. We may need to
port it on Windows by calling Windows APIs to set up signal handler as well.
See the link below for the APIs we may consider to leverage on Windows:
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/signal
In another hand, it seems the functions {{os::kill()}} and {{os::killtree()}}
of Windows version do not send the specific signal to the target process,
{{os::kill()}} handles {{SIGKILL}}, {{SIGSTOP}} and {{SIGTERM}} in the exactly
same way, and {{os::killtree()}} just simply ignore the signal to be sent. So
we may need to improve these two methods on Windows as well.
