[jira] [Updated] (SOLR-4456) Admin UI: Displays dashboard even if Solr is down

JIRA jira@apache.org

     [ https://issues.apache.org/jira/browse/SOLR-4456?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stefan Matheis (steffkes) updated SOLR-4456:
--------------------------------------------

    Attachment: SOLR-4456.patch

[~janhoy] would you mind trying this? I'm mainly interested in the fact if the 'offline'-detection works properly -- having said that, if you're using the UI, shutting Solr down and try to continue, if a dark overlay containing a white box which says "Connection lost ..." appears on your screen?

In addition to that, my idea would be:
* Requesting a ressource (f.e. {{/admin/system}} or sth like that) to discover if we're back online
* If so, displaying another note saying "Reload the Page to continue"

What i would like to do, is: resume the UI where it stopped -- but i'm not sure if that will work out. For that we have to track every single request and try to re-execute it again ..

> 1. Run Solr and bruing up the Admin dashboard
> 2. Stop Solr
> 3. Click around the Admin GUI. It apparently works, but displays a spinning wheel for most panels
> 4. Click on "Dashboard". An old cached dashboard is displayed
> What should happen is that once connection to Solr is lost, the whole Admin UI displays a large red box "CONNECTION LOST" or something :)
