Proposal

• Don’t delete comments when they are deleted from the UI.
• Store them in the database forever.
• Same when you edit a comment. Older versions are stored in the database.
• In the future, we may want to surface these older versions in the UI. But this iteration is just storing them in the database.
• This applies to all comments in GitLab. Issues, mrs, commits, epics.
• Unclear whether this should be a setting.

Why?

• Auditing reasons.
• Security and moderation reasons.
