How to prevent users from deleting commit from remote git repository

Question

I have a git remote repository setup on a shared hosting service with access to git over https. I want to prevent some or all developers from deleting commits from remote repository. How can I achieve this?

Answer 1

With gitolite specifically, you have different types of permissions.
They include a 'D' for deletion:

repo @all
    RWCD dummy-branch = foo

That will authorize the deletion of a branch dummy-branch, but that will also make all your existing RW+ rule deny deletion (because they don't have a 'D')

If a rule specifies RWD or RW+D, then rules that do NOT have the D qualifier will no longer permit deleting a ref.

In that case, you specify who has the right to delete, the others, by default, won't have that right.
