items added to the list or old items deleted from the list. This is a problem in the Restconf parser as these list notification streams can be created in the Java code just fine.</p> <p>Operating System: All<br/> Platform: All</p> YANGTOOLS-622

Improve AbstractStringInstanceIdentifierCodec error reporting

Improvement Highest Confirmed Unresolved Unassigned Jozef Behran Fri, 10 Jun 2016 10:49:25 +0000 Sun, 4 Jul 2021 08:08:42 +0000 codecs 0 6 <p>Steps to reproduce:</p> <p>1. Install ODL with "odl-clustering-test-app" feature installed<br/> 2. Use the tutorial at <a href="https://github.com/opendaylight/docs/blob/master/manuals/developer-guide/src/main/asciidoc/controller/websocket-notifications.adoc" class="external-link" target="_blank" rel="nofollow noopener">https://github.com/opendaylight/docs/blob/master/manuals/developer-guide/src/main/asciidoc/controller/websocket-notifications.adoc</a>, section "Create stream" to attempt to create a notification subscription but use URI "/car:cars/car:car-entry" instead of "/toaster:toaster/toaster:toasterStatus".<br/> 3. You will get the error as reported in the description instead of the expected {"output":{"stream-name":"&lt;some-uri-of-a-websocket&gt;"}} as described in the article.</p> <p>List is mixin node type. It does not represents data.</p> <p>Well, by hooking a notification on a list I want to get updates about new items being created in that list or already present items being deleted. I should get just the item(s) affected in the notification instead of the entire list contents. That should be doable even when the list is a "mixin type which does not represent data".</p> <p>If there is a way to do that, A tutorial needs to be made to do this.</p> <p>Also the error report needs to be improved. When I see an exception like this, I assume something on the server crashed and I am getting info about the crash. And I suspect I am not the only one who tends to make such assumptions on seeing errors like this.</p> <p>It is not possible to do the request on yang list because it is missing key. you can either do the request on following path:<br/> /car:cars/car:car-entry<span class="error">&#91;car:id=&#39;some id&#39;&#93;</span><br/> which would listen on list with given id or you can listen on container cars:<br/> /car:cars<br/> which would listen on any change of this container. Also this error is given in yangtools project so for improved error messaging this should be reported to them.</p> <p>We need to improve the error message which is thrown by XpathStringParsingPathArgumentBuilder to better guide the user. We probably should also create a separate class of Exceptions which RESTCONF can use to translate parsing errors into RpcError details.</p> Relates YANGTOOLS-176 Development Epic Link YANGTOOLS-1023 External issue ID 6048 External issue URL Issue Type ODL SR Target Milestone Rank 0|i028d3:
