Re: [eigen] GitLab migration is starting now!

Maybe you've already done this, but Gitlab projects can be configured to only allow merges if they rebase cleanly:

For other people, here are the steps I needed to take on ubuntu. Suppose
I had a PR from branch my_pr_branch to target_branch on bitbucket. My
user account on both bitbucket and gitlab is peci1. These steps require
manually forking the gitlab repo before and having an SSH key set for
your user/fork.

sudo pip install git-remote-hg
git clone
cd eigen
git remote add hg hg::https://peci1@xxxxxxxxxxxxx/eigen/eigen
git remote add hg-peci1 hg::https://peci1@xxxxxxxxxxxxx/peci1/eigen
git remote add peci1 git@xxxxxxxxxx:peci1/eigen.git
git fetch hg
git fetch hg-peci1
git fetch peci1
git checkout --track origin/target_branch
git checkout -b my_pr_branch
git log hg/branches/target_branch..hg-peci1/branches/my_pr_branch  #
here you'll see hashes of all commits you made on this PR branch

# for each listed commit (from oldest to newest):
git cherry-pick <COMMIT_HASH>
git commit --amend --author="Martin Pecka <peci1@xxxxxxxxx>"  # the
import changed my name to Unknown, so I changed it back

git push peci1 my_pr_branch
# send the Merge request
