- What I did
Fix the issue "'NoneType' object has no attribute 'closelog'" which results from referencing an already destroyed global variable "syslog" when destructuring daemon_base.Logger. The root cause is that python doesn't have a definite sequence in which objects being destroyed when a program exits.
This issue is only observed when sonic_platform/chassis.py is loaded via python shell.
- How I did it
Introduce a class member to represent the "syslog" so that it is accessible during the class destructing.
- How to verify it
verify whether the information can be logged and confirm no error message when the process exits
