gitolite can not limit user to access branch

Question

I create a new branch of a repository, set permissions on the branch, and only allow a certain user to access, the result is that either the user can access all branches(RW dev = user2), or all branches cannot access (- master = user2), please help me and points to the maze. . . the repository can be set to only access and modify a certain branch

Below is my config：

@users  =  user2

repo gitolite-admin
    RW+     =   git1

repo testing
    RW+ master   =   git1

repo repo2
    -   master              =   @users

Answer 1

Double-check the meaning of access: Gitolite cannot restrict read access (if you can see a repository, you see/clone/pull all of the repository)

It can restrict write access (git push)

You could use a combination of separate repositories and partial copies, for selective read control for branches.
See an example here.

You can also restrict Gitolite VREF restrictions to only one branch?
