Hi, I'm having problems listing the available resources for a user. The folder structure looks like following:
ROOT
|-> folder1
    |-> folderA
        |-> resourceA1
        |-> resourceA2
    |-> resourceB
    |-> resourceC


The user "User" has WRITE Resource Permission on the pattern "/folder1/folderA.*", so in principle he can list "folderA" contents.

But the fact is that he can't list it, due to he has not permission on "folder1".

There exist any way to indicate that he can list only the contents of "folderA", but not the resources "resourceB" and "resourceC"? The result should be the following:
ROOT
|-> folder1
    |-> folderA
        |-> resourceA1
        |-> resourceA2


Cheers,
Marc

Well, he actually can list the contents of folder, but not the contents of folder1. If you set folderA as the input of
your viewer all should be good.

Hmm, maybe the array of path segments could be derived from just accessing folderA. I would have to play with it.

In general you seem to have the problem that we do not support partial permissions on objects, i.e., permissions on
feature subsets. You can't grant access to folder1's name and parent folder, but not to its (child) nodes list.

The workaround I'm using now, is to set READ permissions on all the parent folders, and WRITE permission to this folder. But of course it's not a good final solution.

Do you want that I create a bugzilla for that?

Thanks Eike,
Marc

I guess that's what you want to have automated? I can think about it after Kepler...

Yes, please submit a feature request.

Here is the feature request Eike: https://bugs.eclipse.org/bugs/show_bug.cgi?id=410539

If I understood your question, the workaround I have implemented I think it's not the correct behaviour, cause what I want to get is only WRITE permission on "folderA" resource. Giving READ permission on its parent folder, the user can list/read/open the other resources contained in that folder ("resourceB" and "resourceC").

Cheers,
Marc
