git - Deny READ of specific repository branches with gitolite

Question

What I'm trying to achieve is the following: coworkers are in group @coworkers, clients are in group @clients.

The Git repo shall be available to read and write for everyone, but there shall be special branches. i.e. I create a new branch "intern" and @coworkers shall have RW+ acces, but clients should NOT be able to R or W.

I thought i can achieve that by

repo myrepo
    -    intern    = @clients
    RW+            = @clients @coworkers

But this does not work.

Answer 1

According to a discussion with the author of gitolite, read access restriction is not possible for branches:

Gitolite's per-branch stuff works only for write access. It doesn't work for read access because git itself does not support making that distinction.
