Subject [jira] Commented: (JCR-1865) Add the Data Store to the Jackrabbit API
Date Wed, 02 Sep 2009 17:28:32 GMT

    [ https://issues.apache.org/jira/browse/JCR-1865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12750548#action_12750548

Thomas Mueller commented on JCR-1865:
-------------------------------------

> By controlling access to the proposed ManagedRepository interface.

And how do you do that? For the admin session, getRepository() returns a ManagedRepositoryImpl,
and for non-admin sessions, it returns RepositoryImpl? That sounds like a weird solution.
Access rights are 'usually' bound to the user that is logged in (Repository.login()). This
is true for the rest of Jackrabbit, and for other common APIs such as the JDBC API.

>  My point is that management operations like garbage collection, shutdown, etc. should
be outside the scope of normal client connections.

Why is that?

> This way we don't need to invent new access control privileges for such operations.

So you want to have a completely different access rights mechanism? Why?

> > > Do we really need the MarkEventListener mechanism

> Why? 

I need it to do display the progress.  

> Could we achieve the same use case with a simpler API?

Not as far as I know.

> The current implementation can add an observation listener, and this needs to be removed.

Could the listener rather be passed as an argument to mark()? 

The observation listener is an implementation detail of the garbage collector. The user of
the API should have to deal with it.

> best balance

Sure! API design is hard, and it's always good if multiple people look at it.

> Currently, the garbage collection is not part of the Jackrabbit API. However, the data
store garbage collection must be used once in a while if the data store is enabled. I propose
to add the required interfaces to the Jackrabbit API. This will also allow to call garbage
collection using RMI.
