Have you ever accidentally committed to a git repository with a broken user config? No? But your co-workers have?
So, you're stuck with commits like this:
Author: root <root@localhost>
Hotfix on the production server. This was urgent!
Nasty. Or:
Author: John Doe <john@localhost>
Fixed bug #1. Committed on my laptop.
Would it be nice to rewrite history? And take care of committers, as well as of authors? Without all the hassle? Now, you can!
Usage:
$ git-rewrite-authors -w "John Doe <john@localhost>" "John Doe <dearjohn@example.com>"
$ git-rewrite-authors -f author_change_list.txt
Where: authors_change_list.txt (or whatever you want to call it) file contains the list of author / committer changes that need to be changed. Each line in this file would look like this:
Unknown AuthorName <unknown@localhost.com> John Doe <john_doe@realmail.com>
(Unknown AuthorName is the author that needs to be changed, <unknown@localhost.com> is the author's email that needs to be changed, John Doe is the author's name to rewrite, <john_doe@realmail.com> is the author's real email address to rewrite.
You're not sure which authors/committers are hidden in your repository? What about:
$ git-rewrite-authors -l
Tags are rewritten automagically, too!
Enjoy!
