Hot reloading MD-SAL application in karaf container

Bug Resolved Done Michael Vorburger Abhishek Kumar Mon, 16 Mar 2015 20:45:34 +0000 Tue, 25 Jul 2023 08:23:57 +0000 Tue, 4 Jul 2017 20:42:20 +0000 config 0 3 <p>I believed this was for hot reloading of MD-SAL, but that is for your application,<br/> since class reloading is specific (and may require different handling) for each application,<br/> in your case you need to implement handleChangedClass method<br/> and migrate any data you may want during that.</p> <p>We could create another defect for hot reloading of MD-SAL itself. This defect is intended to be for hot reloading applications based on MD-SAL (like the one I have). It uses config subsystem for dependency injection and osgi registration.</p> <p>In the handleChangedClass, I would like to create a new module instance (based on new classes). The new instance creation for module requires "DependencyResolver" that is not passed to this method.</p> <p>Any pointers on how to get a reference to DependencyResolver?</p> <p>Also, since this method handleChangedClass will always need to be implemented by the module, does it make sense to move it out of abstract factory and place inside module factory during code gen?</p> <p>As your explained this is for your application, so this could not be fixed in Controller, but in your app.</p> <p>Closing this as Resolved - Wontfix, since fix is needed in your app.<br/> Please open new feature request for MD-SAL for Berillium.</p> <p>This issue is in the yangtools generated class. Hence, reopening the defect but changing the product to yangtools.</p> <p>If you notice the stacktrace in the description above, the failing method is<br/> AbstractPmnSdnProviderModuleFactory.handleChangedClass().</p> <p>This source code for this class is auto-generated by yangtools and can not be modified by application.</p> <p>Closing - handleChangedClass needs to be customized by user, we can not autogenerate different implementation, since that means bundle got reloaded and may contains incompatible class changes, which effectivelly means yangtools and contoller compontents do not know how it changed, if this change was compatible<br/> and how to migrate state between changes.</p> <p>So we should update description for handleChangedClass which describes in general<br/> that user needs to override it to support bundle reloades and also needs to detect<br/> upgrades of bundle and do state migration.</p> <p>Moving back to controller, since JMX generator is config subsystem generator and is not present in yangtools (never was).</p> <p><a href="https://lists.opendaylight.org/pipermail/mdsal-dev/2016-June/000360.html" class="external-link" target="_blank" rel="nofollow noopener">https://lists.opendaylight.org/pipermail/mdsal-dev/2016-June/000360.html</a></p> <p><a href="https://git.opendaylight.org/gerrit/#/c/40514/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/40514/</a></p> <p><a href="https://git.opendaylight.org/gerrit/#/c/40950/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/40950/</a></p> Development External issue ID 2855 External issue URL Rank 0|i02p7b:
