[Mellanox] Bug fix: exception occurred during chassis object being destroyed#66
Conversation
The following error message is observed during chassis object being destroyed ``` Exception ignored in: <function Chassis.__del__ at 0x7fd22165cd08> Traceback (most recent call last): File "/usr/local/lib/python3.7/dist-packages/sonic_platform/chassis.py", line 83, in __del__ ImportError: sys.meta_path is None, Python is likely shutting down ``` The chassis tries to import deinitialize_sdk_handle during being destroyed for the purpose of releasing the sdk_handle. However, to import another module during shutting down can causing error because some of the fundamental infrastructure is no longer available. To fix it, record the deinitialize_sdk_handle in chassis object when sdk_handle is being initialized and call the deinitialize handler when chassis object is being destroyed Signed-off-by: Stephen Sun <[email protected]>

Why I did it
The following error message is observed during chassis object being destroyed
The chassis tries to import deinitialize_sdk_handle during being destroyed for the purpose of releasing the sdk_handle.
However, importing another module during shutting down can cause the error because some of the fundamental infrastructures are no longer available.
This error occurs when a chassis object is created and then destroyed in the Python shell.

How I did it
To fix it, record the deinitialize_sdk_handle in the chassis object when sdk_handle is being initialized and call the deinitialize handler when the chassis object is being destroyed
How to verify it
Manually test.
