| == Usage examples == Let suppose we have the following repository {{{#!dot digraph { rankdir=LR node [shape=box] C1 -> C2 -> R1 -> R2 C2 -> L1 -> L2 } }}} 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: {{{#!dot digraph { rankdir=LR node [shape=box] C1 -> C2 -> R1 -> R2 -> l1 -> l2 } }}} == 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 * continue === 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 }}} |

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.
In general, this extension allows to move revisions from a point to another, some common scenarios are shown in the section "Scenarios".
This feature has been implemented as part of SummerOfCode/2008.
Current implementation
The current code can be found here and here (old repository). This project is distributed along with Mercurial release 1.1 as RebaseExtension.
Current version's features:
- rebase both simple and complex cases
- abort of an interrupted rebasing
- resume of an interrupted rebasing
- mq patches handling
- detect changes during interruptions
