Subject [jira] Reopened: (GERONIMO-4306) Plugin list won't be updated after installing a new server plugin
Date Fri, 19 Sep 2008 14:38:44 GMT

     [ https://issues.apache.org/jira/browse/GERONIMO-4306?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lin Sun reopened GERONIMO-4306:
-------------------------------

      Assignee:     (was: Jarek Gawor)

Currently, the plugin or app module list is stored along with PortletSession and it will be
expired whenever the PortletSession is expired.   We did this on purpose as it is expensive
(I can notice the slow down for a few seconds) to get the list from server whenever the page
is visited.

I'd prefer to have a refresh button (within the portlet) to explicitly for the user to refresh
the plugin or app module list whenever the user desires to do so.   Otherwise, we'll just
retrieve the cached data.   Thoughts?

>          Components: console
>    Affects Versions: 2.1.3

> Steps:
> 1. Login web console
> 2. Go to "Plugin -> Assemble Server" portlet, and click the button - "Assemble a server",
then get the current plugin list.
> 3. Go to "Plugin -> Install Plugins" portlet to install a new plugin
> 4. Go back to the "Assemble Server", and click the button, then the list is not updated.
> Proposed fix:
> 1.
> In "AssemblyListHandler.java", we cached the plugin list in portlet session, and that
won't be updated after installing a new plugin by web console.
> If we add codes to refresh the session after installing a plugin in "Install Plugins"
portlet, it seems to solve this problem. But it does not work for using the gsh to install
new plugins.
> So, we have to let the AssemblyListHandler load the plugin list each time we open the
portlet. And good news is that I did not see any significant performance falling.
> 2.
> And another method to solve this problem is that  "ask user to logout and login back
when they install some plugins if they want to see their plugins list in the 'assemble Server'
portlet", but is it acceptable?
> If the #1 is more reasonable, I can provide a patch. 
> Thanks
