It seems to work fine here:

  https://gitlab.com/abologna/libvirt/-/jobs/522467078

The corresponding commit is

  https://gitlab.com/abologna/libvirt/-/commit/435ef06536f590f4403d0ce59a1b9edc1dfa80ec

where I changed the local require-dco.py script to use the very same
branch I pushed to as the base branch for DCO checking.

I believe you fixed the issue you mention above with

  commit 769ff77c9c5afaec97350a4931e5ca123b6af6d2

    scripts: avoid error in DCO check on empty branches

    If the DCO check is run on an empty branch (ie one which has no commits
    different from master), it throws an error due to trying to interpret
    the empty string as a git commit SHA.

  v6.1.0-306-g769ff77c9c

So I see no reason not to just run the check on all branches.


If you remove the except: part, and of course the corresponding
comment as well, then
