[YANGTOOLS-613] SchemaResolutionException caused by multiple revisions of model and its dependent models in the runtime

Sun, 10 Apr 2022 18:35:47 +0000

I have an application that has a dependency on the IETF standard model shown below. So, I have ietf-network@2015-12-08.yang and ietf-network-topology@2015-12-08.yang in my controller system.

module ietf-network-topology {
namespace "urn:ietf:params:xml:ns:yang:ietf-network-topology";
prefix nt;
...
import ietf-network

{ prefix nd; }

revision 2015-12-08 { }
...
}

Although the IETF model doesn't specify the revision of ietf-network that it depends on, it actually depends on the ietf-network@2015-12-08.yang (There was a model change in Nov 2015 that makes this dependency important).

In my controller, I also have odl-mdsal-models feature installed with ietf-network bundle of version 1.0.1-Beryllium-SR1. This bundle includes ietf-network-topology@2015-06-08.yang and ietf-network@2015-06-08.yang.

Since yangtools picks the latest version, the ietf-network@2015-06-08.yang is not visible to other modules. However, ietf-network-topology@2015-06-08.yang is not suppressed from the runtime. This causes dependency issues because yangtools offers ietf-network@2015-12-08 to ietf-network-topology@2015-06-08's import. This throws the following error:

{path=[(urn:ietf:params:xml:ns:yang:ietf-network?revision=2015-12-08)network, (urn:ietf:params:xml:ns:yang :ietf-network?revision=2015-12-08)node]}
