As part of fallout from the migration to gerrit1001 (T236114), we have only fixed refs/changes/*/*/meta references. When I have updated my copy of All-Users.git, I noticed some references have been force updated:
From ssh://gerrit.wikimedia.org:29418/All-Users + 568a83712...fae088973 refs/users/22/7622 -> origin/users/22/7622 (forced update) + 0276d6063...c988a30d5 refs/users/68/868 -> origin/users/68/868 (forced update) + fcdd059f3...1ce35db10 refs/users/72/7372 -> origin/users/72/7372 (forced update) + a0359d94e...ea5986069 refs/users/87/787 -> origin/users/87/787 (forced update)
That is based on the snapshot I had on my local machine, but it should be compared with whatever was on cobalt instead.
@thcipriani I guess we want to run the magic comparison script against all references? I think we only looked at refs/changes/* by simply using git ls-remote . refs/changes/*/*/meta.
