Question

My use case is this:

I am working on a new feature and I have several commits on that feature.
Since it was a minor feature, I didn’t even consider doing the feature in a feature branch.

However. Now my boss comes along and tells me to fix a bug on the same branch that I am working on (default).

To fix that I’d like to create a feature branch for my feature, push all my existing (unpushed) commits into that branch.

So I’d like to create a branch just before my first commit and then somehow move all my commits to that branch.

How can I do this?

There’s two ways to approach this, depending on your preference:

1. In a new repository.

   Make a new clone of your repository, and do the bug fix you need to make there. Then push it to the main repository when you’re done, and continue where you left off in the original repository. Pull and merge to get the new changes as usual.

2. In the existing repository.

   Update to the changeset before your local changes, and just start fixing and committing there. This creates a new anonymous branch. When you’re done, push using push -r ., this will only push the changes that are included in the working copy. After this, merge with your original branch (hg merge) and continue where you left off.

   Note that you can bookmark the feature branch with hg bookmark if you do not feel comfortable with leaving your changes unlabeled. Also you can easily find back any heads you left behind using hg heads.

Personally I prefer to work in a new clean clone, as you don’t need to worry about branching and where to leave uncommitted changes. However if your project setup is complicated it may be more convenient to reuse the existing repo.
