    ExternalProject: Ensure git fetch if updating to hash we don't have yet · 5e941a54
    Craig Scott authored
    In ac6a4d48 (ExternalProject: Improve robustness of update step,
    2020-10-17), the method used to check whether we already have a
    commit or not was changed from using git rev-list to git rev-parse.
    The new logic assumed rev-parse would output nothing if given a commit
    hash it didn't know about, but it simply prints the hash again without
    raising an error in this scenario. Amend that logic by adding ^{commit} to
    the ref to ensure we do get an error if that ref is not currently known.
    
    Fixes: #22166
