Error occurs when mdsal binding v1 codec a "union" type

I noticed that<br/> org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.routing.types.rev170227.MplsLabel<br/> does not have getMplsLabelSpecialPurpose getter,</p> <p>but mpls-label defines it:</p> <p> typedef mpls-label {<br/> type union </p> { type mpls-label-special-purpose; type mpls-label-general-use; } <p>This causes similar failure when we try to configure labels in Honeycoimb via restconf.</p> <p>The problem is located in TypeProviderImpl.resolveExtendedSubtypeAsUnion(), where we ignore the union type as it is derived from an IdentityRef and there is no case statement to assign it.</p> <p>Actually, for some reason we do not generate a type for 'typedef mpls-label-special-purpose', which means the union cannot find the type and fails to add the union member.</p> <p>Oxygen: <a href="https://git.opendaylight.org/gerrit/67757" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/67757</a></p> <p>This also affects binding-v2, but that needs to be addressed separately.</p> <p>LeafrefTypeDefinition was fixed previously in <a href="https://jira.opendaylight.org/browse/MDSAL-253" title="BindingToNormalizedNodeCodec fails to deserialize union of leafrefs" class="issue-link" data-issue-key="MDSAL-253"><del>MDSAL-253</del></a>, but that did not fix IdentityrefTypeDefinition nor binding2.</p> <p>Root Cause Analysis:</p> <p>This issue comes from the decision to not change generated identityref leaf method signature, which means we cannot provide typedef-mandated encapsulation of the identity reference. Hence no encapsulation is done for both identityref and leafref nodes.</p> <p>While <a href="https://jira.opendaylight.org/browse/MDSAL-253" title="BindingToNormalizedNodeCodec fails to deserialize union of leafrefs" class="issue-link" data-issue-key="MDSAL-253"><del>MDSAL-253</del></a> took care of the leafref special case for unions, identityref typedefs were not handled and dropped silently.</p> <p>The fix makes unions aware of identityref and wires them to the leafref case, which produces expected results.</p> <p>The patch actually does not fix anything. I can now see the problem, codec expects:</p> <p>Caused by: java.lang.NoSuchMethodException: org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.routing.types.rev170227.MplsLabel.getMplsLabelSpecialPurpose()<br/> at java.lang.Class.getMethod(Class.java:1778)</p> <p>while codegen generates:</p> <p>    public java.lang.Class&lt;? extends org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.routing.types.rev170227.MplsLabelSpecialPurposeValue&gt; getClassMplsLabelValue() </p> {         return _classMplsLabelValue;     } <p>e.g. codegen does not take the typedef into account at all, while it should for naming purposes – the method name is derived from the identity name, not the type name of the identityref. That actually should be simpler to fix (I hope).</p> <p>Updated patch generates the property correctly.</p> <p>Property generation works indeed, but now I get some run time issues during deserialization,</p> <p>that look similar to <a href="https://jira.opendaylight.org/browse/YANGTOOLS-742" title="Getter of BA object fails to construct class instance" class="issue-link" data-issue-key="YANGTOOLS-742"><del>YANGTOOLS-742</del></a>.</p> <p>Stack trace:</p> <p>Caused by: java.lang.IllegalArgumentException: Failed to construct instance of class org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.routing.types.rev170227.MplsLabel for input (urn:ietf:params:xml:ns:yang:ietf-mpls-static?revision=2017-03-10)111<br/>     at org.opendaylight.yangtools.binding.data.codec.impl.UnionTypeCodec.deserialize(UnionTypeCodec.java:114) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.LeafNodeCodecContext.deserializeObject(LeafNodeCodecContext.java:199) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.DataObjectCodecContext.getBindingChildValue(DataObjectCodecContext.java:324) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.LazyDataObject.getBindingData(LazyDataObject.java:148) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.LazyDataObject.bindingToString(LazyDataObject.java:205) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.LazyDataObject.invoke(LazyDataObject.java:65) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at com.sun.proxy.$Proxy115.toString(Unknown Source) ~<span class="error">&#91;na:na&#93;</span><br/>     at java.lang.String.valueOf(String.java:2994) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at java.lang.StringBuilder.append(StringBuilder.java:131) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at com.google.common.base.MoreObjects$ToStringHelper.toString(MoreObjects.java:350) ~<span class="error">&#91;guava-22.0.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.LazyDataObject.bindingToString(LazyDataObject.java:210) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.LazyDataObject.invoke(LazyDataObject.java:65) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at com.sun.proxy.$Proxy112.toString(Unknown Source) ~<span class="error">&#91;na:na&#93;</span><br/>     at java.lang.String.valueOf(String.java:2994) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at java.lang.StringBuilder.append(StringBuilder.java:131) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at com.google.common.base.MoreObjects$ToStringHelper.toString(MoreObjects.java:350) ~<span class="error">&#91;guava-22.0.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.LazyDataObject.bindingToString(LazyDataObject.java:210) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at org.opendaylight.yangtools.binding.data.codec.impl.LazyDataObject.invoke(LazyDataObject.java:65) ~<span class="error">&#91;mdsal-binding-dom-codec-0.11.2-SNAPSHOT.jar:na&#93;</span><br/>     at com.sun.proxy.$Proxy111.toString(Unknown Source) ~<span class="error">&#91;na:na&#93;</span><br/>     at java.util.Formatter$FormatSpecifier.printString(Formatter.java:2886) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at java.util.Formatter$FormatSpecifier.print(Formatter.java:2763) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at java.util.Formatter.format(Formatter.java:2520) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at java.util.Formatter.format(Formatter.java:2455) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at java.lang.String.format(String.java:2940) ~<span class="error">&#91;na:1.8.0_151&#93;</span><br/>     at io.fd.honeycomb.translate.write.WriteFailedException$CreateFailedException.getMsg(WriteFailedException.java:114) ~<span class="error">&#91;translate-api-1.18.01.1-SNAPSHOT.jar:na&#93;</span></p> <p> </p> <p> </p> <p>This exception is thrown when no member codec accepts the incoming value.
