Who can access source code?

Overview

You can specify access permissions for users with a given role at the repository level, or at at the path level within a repository.

When you set a permission for a role on any directory in the repository, all directories and files under that directory get the same permission.
When you set a permission on an individual file in the repository, there is no effect on the permissions assigned to paths above the level of that file. (files are just "paths" that terminate with a file names)

How you use path-based permissions will depend on whether you view permissions primarily as a way to grant access or as a way to restrict access.

Full access, with exceptions: Give your company's own employees commit access to your whole source code base, while allowing developers from contracting firms to commit only to those parts of the code base that they are expected to work on.
No access, with exceptions: Assign all developers "No access" by default, then assign each type of developer access to certain directories and files according to their responsibilities.

Note: You can control access to a path or to an individual file. This is different from normal Subversion checkout and commit operations, which are performed on directories but not individual files.

No Access

When you deny all access to a repository for a role, users with that role cannot see that the repository exists, except if:

The role has View or Commit access to some directory within the repository. In this case, users with this role can see the directories that contain the directory they have access to.
The user has another role that grants access to some part of the repository.

Note: An individual user can have multiple roles. When two roles have permissions that conflict with each other, the role with the more expansive permissions takes precedence.

View Only

Users with a role that has View Only access to a path can browse the contents of the repository on the Web site or by connecting directly to the repository from a client, such as Tortoise, CollabNet Desktop for Eclipse, or CollabNet Desktop for Visual Studio.

View and Commit

Users with a role that has View and Commit permission to a path can browse and download code, and can also check code into the repository.

Commit messages

When users monitor a repository, they receive commit announcements by email that include the resources that their role permits them to see.

Users with a No Access role on a repository cannot monitor that repository to receive commit messages by email.

By default, commit emails provide all the details about the commit that a logged-in user can view in the Source Code application. A repository owner can elect to have the notification emails omit most of the detail and provide only the commit ID and the committer's user name.

Permissions at different levels

If two paths have different permissions, the permissions on the lower-level path take effect. For example, consider a role that has "No Access" set for the path /branches/version3/users, but has "View and Commit" access to /branches/version3/users/vijay. A user with this role can:

Check code in and out of the vijay directory.
Click down through all the directories in that path, including users. (Directories that are not included in the user's permissions are not shown.)

Users with this role cannot:

Check files in and out of the users directory.
Monitor commits to users.
Execute Subversion copy, move or delete operations that involve resources in the users directory (or any other paths where the user has View Only or No Access).
