[YANGTOOLS-790] BGP models not compatible with leafref context

Sun, 10 Apr 2022 18:36:00 +0000

While trying to create LeafRefContext(yangtools) it appears that bgp models contains some leafref configuration that is invalid. Following error is showed

Can be reproduced with following test:

public class LeafRefContextTest {

private static final String YANG_BA_PROVIDER_PATH = "META-INF/services/" + YangModelBindingProvider.class.getName();

@Test
public void testLeafRefContextCreation()

{ assertNotNull(LeafRefContext.create(context())); }

private SchemaContext context()

{ ModuleInfoBackedContext ctx = ModuleInfoBackedContext.create(); final Set<YangModuleInfo> modules = modules(); checkState(!modules.isEmpty(), "No modules found"); ctx.addModuleInfos(modules); return ctx.getSchemaContext(); }

private Set<YangModuleInfo> modules() {
try

{ return Collections.list(getClass().getClassLoader().getResources(YANG_BA_PROVIDER_PATH)) .stream() .map(LeafRefContextTest::urlToString) .flatMap(content -> Arrays.stream(content.split("\n"))) .filter(line -> !Strings.isNullOrEmpty(line.trim())) .map(LeafRefContextTest::loadClass) .map(LeafRefContextTest::getInstance) .map(YangModelBindingProvider.class::cast) .map(YangModelBindingProvider::getModuleInfo) .collect(Collectors.toSet()); }

catch (IOException e)

{ throw new IllegalStateException("Unable to load binding providers from path: " + YANG_BA_PROVIDER_PATH, e); }

}

private static Object getInstance(@Nonnull final Class<?> aClass) {
try

{ return aClass.newInstance(); }

catch (InstantiationException | IllegalAccessException e)

{ throw new IllegalStateException("Unable to create instance of " + aClass); }

}

private static Class<?> loadClass(@Nonnull final String className) {
try

{ return Class.forName(className); }

catch (ClassNotFoundException e)

{ throw new IllegalArgumentException("Unable to load class: " + className, e); }

}

private static String urlToString(@Nonnull final URL url) {
try

{ return Resources.toString(url, Charsets.UTF_8); }

catch (IOException e)

{ throw new IllegalArgumentException("Unable to read resource from: " + url, e); }

}
}
