Support both 0 and NULL lock_versions (!24050) · Merge requests · GitLab.org / GitLab FOSS · GitLab

Douwe Maan requested to merge dm-lock-version-null into master Dec 27, 2018

What does this MR do?

Ensures that issues and MRs left with a lock_version of 0 after https://gitlab.com/gitlab-org/gitlab-ce/issues/55611 can be updated and destroyed.

This only affects instances that run nightlies, so it doesn't require a changelog item.

Does this MR meet the acceptance criteria?
