vided the commit verifies the authorization invariant. In the example below, A is a common ancestor of the introductory commit I and of commit X. Authentication of X would succeed, even though it is not a descendant of I, as long as X is authorized according to the '.guix-authorizations' in A: X I \ / A This is because, 'authenticate-repository' would not check whether X descends from I, and the call (commit-difference X I) would return X. In practice that only affects forks because it means that ancestors of the introductory commit already contain a '.guix-authorizations' file. * guix/git-authenticate.scm (authenticate-repository): Add call to 'commit-descendant?'. * tests/channels.scm ("authenticate-channel, not a descendant of introductory commit"): New test. * tests/git-authenticate.scm ("authenticate-repository, target not a descendant of intro"): New test. * tests/guix-git-authenticate.sh: Expect earlier test to fail since 9549f0283a78fe36f2d4ff2a04ef8ad6b0c02604 is not a descendant of $intro_commit. Add new test targeting an ancestor of the introductory commit, and another test targeting the v1.2.0 commit. * doc/guix.texi (Specifying Channel Authorizations): Add a sentence.
