Solution 1

Like (almost) everything else with Git, this command only modifies your local repository. Just like when you commit or add a tag, you will have to push to BitBucket in order to make the changes show up.

But before you do, be very sure that you want to.

The filter-branch command that you ran rewrote your history. Each of your commits now has a new hash. It is considered bad practice to rewrite history that has been shared with others, and if you push to BitBucket you'll be doing that.

This can cause real problems, most obviously because anybody else who has cloned the repository will now have history that is no longer reflected in the repository. They will have trouble pushing and fetching (or pulling). If you choose to go forward, it is best to carefully and honestly communicate with all of your collaborators.

If you are very, very sure that you want to do this, you'll have to use the --force-with-lease option to push, or else BitBucket will reject the push.

Solution 2

Like Chris said, it is a bad practice to rewrite your git history.

The recommended way to map authors is to use the .mailmap feature.

Create a .mailmap file at the top level of your repository with the following content:

New Name <[email protected]> Old Name <[email protected]>

This will replace Old Name <[email protected]> in git history with New Name <[email protected]> and these changes will also reflect on Github and Bitbucket.

Solution 3

Also to change authors in Git for a particular project, one may run:

git config user.name "Author Name"
git config user.email "[email protected]"

Solution 4

1. git filter-branch rewrites your history. This can cause problems if you have shared your repository with other people, so be careful!
2. Make sure you have pushed the result of the filter-branch operation to the remote repository. Since you have messed with historic commits, you probably need to use git push -f for this. git push (without -f) will notice you of the fact that your local and remote branches have diverged, this is because of the fact that you have rewritten your history. Again, be careful before you use git push -f!
3. Sites like Bitbucket and GitHub try to link commits to users instead of simply displaying the commiter's name. This is done by matching the committer's email address to an email address that is associated to one of their users. If you expect Bitbucket to show a link to your user profile, make sure that you have added the new email address to your account. To do so, click on your profile photo in the upper right corner of the site, click 'Manage account', and then in the left sidebar click on 'Email addresses'.
