Rebase Project

Introduction

When contributing to a project, sometimes there is the need to keep some patches private, while keeping the whole repository up-to-date.

In those cases it can be useful to "detach" the local changes, synchronize the repository with the mainstream and then append the private changes on top of the new remote changes. This operation is called rebase.

This feature is being implemented as part of SummerOfCode.

Current implementation

The current code can be find [http://freehg.org/u/astratto/soc/ here]

Current version's features:

Usage examples

Let suppose we have the following repository

where C* are common revisions, R* changes in upstream and L* local changes.

Simple case

We want to rebase L* on top of R2.

This can be achieved using: 

   $ hg rebase L1 R2

Result:

Dealing with conflicting merges

Sometimes could happen that some changes in L* conflicts with some changes in R*. In these cases the extension will stop, store the current status and let user the ability to solve the conflict on his own.

In event of interruption users have two choices:

Abort

An interrupted process can be aborted, thus restoring the repository to its original state, with:

 hg rebase --abort 

Continue

The most common situation, however, is resuming an interrupted process and this can be done with:

 hg rebase --continue
