What I did
I moved getAclBindPortId from portsorch to aclorch.
Why I did it
This serves two purposes:
There was a bug wherein AclTable::update would fail to handle port deletion events because the getAclBindPortId method lived in portsorch. Because this method was using the provided alias to get the OID internally, this method would fail in the delete case because the port had already been deleted from portsorch. As a result, all delete events would fail and print a "Unable to retrieve OID" method. This was caught by the
test_po_updatepytest because it deletes the PortChannel at the end of the test case, which triggers a delete event, which triggers this bug.The behavior implemented in this method is specific to the ACL implementation in SONiC, and it doesn't really make sense to include it in the more generic AclOrch. Furthermore, we have access to all the port info in AclOrch, so there is no need to take a dependency on PortsOrch to fetch the port OID info and perform the parsing logic. There was a
TODOindicating the same.How I verified it
test_po_updatepasses in the master image now. I also re-ran theaclandeverflowtests and everything looks good to go.Details if related
