There are other ways to fix old names against old commits, but they involve recreating the entire git history since then. That's not always feasible

@nerdnz@cloudisland.nz I did a history rewrite using .mailmap when I supported a company to open source an application, because the commits on Bitbucket contained user IDs. 😬 But what I didn't know is that it also changes the output of git, thanks for highlighting that.

@nerdnz@cloudisland.nz If rewriting history is an option, I can recommend git-filter-repo: https://github.com/newren/git-filter-repo

@nerdnz@cloudisland.nz The .mailmap solution is only visible for you, the git filter-branch solution is visible for everyone. And it is necessary far more often then when you change your name, because far more people change their e-mail address. https://www.reddit.com/r/github/comments/12931oe/change_emailname_on_existing_commits/
