Alexander Klimetschek commented on SLING-3420:
----------------------------------------------
Oh, yes, sorry for the confusion, the getResourcePath() method is not as I
assumed it - it just gives information back on what currently would be the real
resource path used. Which is ok for me.
I think this would be cleaner (and IIRC was in Gilles' original patch) by
exposing the MergedResource interface and provide it with the necessary
"insight" methods. I.e. ResourceMergerService would return MergedResource
directly in its getMergedResource() (current API) or merge() (my proposal).

> Key: SLING-3420
> URL: https://issues.apache.org/jira/browse/SLING-3420
> Project: Sling
> Issue Type: New Feature
> Components: Extensions
> Affects Versions: Resource Merger 1.0.0
> Reporter: Carsten Ziegeler
> Assignee: Carsten Ziegeler
> Fix For: Resource Merger 1.0.2
>
>
> The resource merger merges resources from the search paths. This is very
> useful for reading/getting such resources.
> However, as soon as you want to modify, create or delete such resources the
> code doing so needs more knowledge about how the resource merger works. And
> the code needs to switch from the mount path to a search path etc.
> Therefore, the resource merging provider could directly implement the
> modifying resource provider:
> - if the resource resolver is configured with less than two search paths,
> modifying is denied
> - the last search path (e.g. by default /libs/) is considered to be
> unchangeable, so all operations are done on a higher search path
> 1. Create
> This creates a node at the second last search path (e.g. /apps)
> 2. Delete
> If there is a node at /libs, a node hiding this one is created at /apps.
> Otherwise the node at /apps is removed
> 3. Update
> Creates/updates a node at /apps
> All these methods need to check whether resource hiding is used and adjust
> the properties accordingly
