SVN folder (not repository-wide) permissions

Question

I am a bit new to SVNed code.

We are a small team (4 people) divided into two duos.
Each of the duos has its own disjoint share of the project.
I want to be able to SVN a project to a single repository with the following:

• each duo, should be able to write to it's own "section" of the rep'.
• each duo, should be able to read-only the other duo's section.

Can this be done on a single repository?
Are there folder-specific, rather than repository-wide permissions? Is this hosting/repository service dependent? I am currently hosted at XP-Dev.

Would appreciate any kind of comment or reference. David

I think your best bet is to use Subversion's path-based authorization. This may be hosting-service dependent - you'll have to ask around at XP-Dev to find out if they support it.

An example would be something along the following lines:

[groups]
proj1-developers = harry, joe
proj2-developers = frank, sally

[proj1:/projects/proj1]
@proj1-developers = rw
@proj2-developers = r

[proj2:/projects/proj2]
@proj1-developers = r
@proj2-developers = rw

This can also be used in conjunction with Apache-based per-directory access control (using the AuthzSVNAccessFile directive) and password-based access (using the AuthUserFile directive pointing at a file created using htpasswd). I'm currently using all three successfully, and also added on optional LDAP authentication. It helps when you have full access to the repository server.
