DataChangeListener unable to read created data

Bug Resolved Done Unassigned Robert Gallas Tue, 24 Jun 2014 13:08:58 +0000 Tue, 25 Jul 2023 08:23:56 +0000 Wed, 25 Jun 2014 10:47:14 +0000 mdsal 0 3 <p>You are reading from Operational DAta but you are posting to configuration<br/> data tree. Please update your code<br/> to change.getCreatedConfigurationData() and change.getUpdatedConfigurationData().</p> <p>Operational data CAN NOT be updated via Restconf, that is why you see<br/> this fields empty.</p> <p>Marked this as Resolved - Invalid, since Data Change Listeners (using <b>Configuration</b>) methods are verified to be working with Restconf.</p> <p>(<a href="https://jenkins.opendaylight.org/integration/job/integration-master-csit-base-of13/" class="external-link" target="_blank" rel="nofollow noopener">https://jenkins.opendaylight.org/integration/job/integration-master-csit-base-of13/</a> - test restconf puts, components process data as data changes).</p> <p>Sorry may fault: <br/> Of course reading configuration data an not operational data is what fails:</p> <p> logger.info("onDataChanged change.getCreatedConfigurationData().entrySet().size()={}",<br/> change.getCreatedConfigurationData().entrySet().size());<br/> logger.info("onDataChanged change.getUpdatedConfigurationData().entrySet().size()={}",<br/> change.getUpdatedConfigurationData().entrySet().size());</p> <p>ends up with:<br/> 2014-06-25 08:49:09.190 CEST <span class="error">&#91;pool-15-thread-2&#93;</span> INFO o.o.c.i.d.a.i.h.ServiceXXXListener - onDataChanged change.getCreatedConfigurationData().entrySet().size()=0<br/> 2014-06-25 08:49:09.191 CEST <span class="error">&#91;pool-15-thread-2&#93;</span> INFO o.o.c.i.d.a.i.h.ServiceXXXListener - onDataChanged change.getUpdatedConfigurationData().entrySet().size()=0</p> <p>As I said in bug creation data are inserted in data store but deserialization fails at data change listener.</p> <p>Hovever there is a difference in output: when logger contains code to read configuration data exception is thorwn:</p> <p>So the steps are:<br/> 1. init application<br/> 2. send restconf post with data<br/> Async listener events:<br/> if change.getCreatedConfigurationData().entrySet() is called, entry set equalls zero and deserialization exception is thrown<br/> if change.getCreatedOperationalData().entrySet() is called entry set equalls to zero (which is correct) but not exception is thrown.<br/> 3. successful return from restconf post<br/> 4. restconf get confirms data are uploaded to store</p> <p>Root cause of exception seems to be:<br/> Caused by: java.lang.ClassNotFoundException: org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.yang.types.rev130715.MacAddress</p> <p>Meaning that even data are succesfully uploaded to datastore</p> <p>1. in listener I'm unable to read change<br/> 2. exception is thrown based on reading config or operational data because of ClassNotFoundException, but missing class does not prevents data to be stored in datastore<br/> 3. fails to read (deserialize) but not to store data in data store. Seems like dual approach in handling datastore operations. (guess only of course)</p> <p>Code is proprietary so I cannot post code. So only code samples</p> <p>Referencig yang:</p> <p>...<br/> import ietf-yang-types </p> { prefix "yang"; } <p>...<br/> leaf mac-address {<br/> type yang:mac-address;<br/> ...<br/> }<br/> ...</p> <p>In cache there are two ietf-yang-types and both of them contains:<br/> ...<br/> typedef mac-address {<br/> type string {<br/> pattern '<span class="error">&#91;0-9a-fA-F&#93;</span></p> {2}(:<span class="error">&#91;0-9a-fA-F&#93;</span>{2} <p>)</p> {5} <p>';<br/> } <br/> ...</p> <p>referencing YANG needes to reference ietf-yang-types by revision as well. After adding revision listener works OK.</p> Development External issue ID 1240 External issue URL Rank 0|i02la7:
