Subject [jira] [Commented] (KARAF-2894) Uninstalling a feature should remove referenced config data
Date Sun, 20 Apr 2014 15:34:16 GMT

    [ https://issues.apache.org/jira/browse/KARAF-2894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13975163#comment-13975163
] 

Jean-Baptiste Onofré commented on KARAF-2894:
---------------------------------------------

I disagree as a default behaviour. In another Jira, I proposed to add an attribute on <config/>
and <configfile/>: override="true" and append="true".

Moreover, override attribute already exist for <configfile/> (I have to check for <config/>).

So you can already use it.

>                 URL: https://issues.apache.org/jira/browse/KARAF-2894
>             Project: Karaf
>          Issue Type: Improvement
>          Components: karaf-config, karaf-feature
>    Affects Versions: 3.0.0
>            Reporter: Simon Watson
>
> Config data specified in a feature, either using <config> or <configfile>,
should be removed when the feature is uninstalled.
> This prevents a new version of a feature updating its config data.
> Example use case:
> I tried deploying the following feature as feature-test.xml in the /deploy dir of Karaf
3.0.0: 
> <?xml version="1.0" encoding="UTF-8"?> 
> <features name="test-features">
>         <feature name="config-test" version="1.0.0">
>                 <config name="my.new.config">
>                         my.key = my.value 
>                 </config>
>         </feature>
> </features>
> I then install it: feature:install config-test 
> And I see the following config created: config:list "(service.pid=my.new.config)" 
> Pid:            my.new.config 
> BundleLocation: null 
> Properties: 
>    service.pid = my.new.config 
>    my.key = my.value 
>    org.apache.karaf.features.configKey = my.new.config 
> But I don't see any matching file created in /etc. 
> When I uninstall the feature with "feature:uninstall config-test" I still see the config
data appearing in config:list. 
> Moreover, if I uninstall the feature, modify the deploy/feature_test.xml to: 
> <feature name="config-test" version="1.0.1">
>                 <config name="my.new.config">
>                         my.key = my.value2 
>                 </config>
>         </feature>
> and then install the new feature version. I still see the old config data in config:list.
