Dynamic port configuration - add port buffer cfg to the port ref counter #2194

dprital · 2022-03-23T17:50:06Z

What I did

This PR replace PR #2022

Added increasing/decreasing to the port ref counter each time a port buffer configuration is added or removed
Implemented according to the - sonic-net/SONiC#900

Why I did it
In order to avoid cases where a port is removed before the buffer configuration on this port were removed also

How I verified it
VS Test was added in order to test it.
we remove a port with buffer configuration and the port is not removed. only after all buffer configurations on this port were
removed - this port will be removed.

we should remove_port, add_port, then remove_port (port will with buffer_cfg, when remove you will remove buffer cfg first, and when you add, you will add buffer cfg after) to see if things are as expected. This is to explicitly excise the ref counters during those operations. maybe we can have a test case like "test_remove_add_remove_port_with_buffer_cfg" ?

@zhenggen-xu
to me, this is a negative test that verifies a port will not be removed if there is a buffer configuration on it. We should keep this test.
So i would like to have the test test_remove_add_remove_port_with_buffer_cfg like this:

when removing the port for the first time, remove port first and then the buffer configuration. verify the port will not be removed without buffer configuration cleared.

when adding the port, add the port first and then the buffer configuration, as you suggested.

when removing the port for the second time, remove the buffer configuration and then the port, as you suggested.
By doing so, we are able to verify both orders.

How do you think?

@stephenxs sounds good to me.

Updated test case. It's a bit different compared with what I suggested yesterday.
What I suggested:

for the first removing, remove the port and then buffer configuration

for the second removing, remove the buffer configuration and then port

What I implemented:

for the first removing, remove the buffer configuration and then the port

for the second removing, remove the port and then buffer configuration

Compared with the original approach, we do not need to check whether the buffer configuration has been successfully re-added after it was added back when the port was recreated: if it is not successfully added, the following port removing can succeed without removing buffer configuration, which will fail the test. Neither do we lose coverage.
@zhenggen-xu can you please review it?

Sure, looks good to me.

@dprital what is the status of this PR? do you have an ETA to fix the tests

dprital · 2022-08-23T23:30:37Z

@neethajohn , @zhenggen-xu - This is an old PR which was approved by you, as the checkers failed for some time, i fixed the test and now it pass. Would l ike to ask you to look at it (the code was not changed, only the test itself) and I would like you to approve so it will be able to be merged. Thanks in advance!
