The Rebase command allows you to apply commits from one branch to another. Rebase can be viewed as more powerful version of Cherry-Pick, which is optimized to apply multiple commits from one branch to another.
Rebase “moves” (actually “rewrites”) the commits below the HEAD to the selected commit. The HEAD will be moved to the new fork.
o [> master] A o [> master] A' | | o B o B' | | o C o C' | | | o [a-branch] D | o [a-branch] D | | | / | | | / | o E (selected) ===> o E | / | | / | o F o F
To Rebase Onto you may use the Log window.
Consider following example where the
quickfix2 branch should not start at the
quickfix1 branch, but rather on the
q2b (quickfix2) | q2a | q1b (quickfix1) | q1a | x (master) | ...
To achieve this, just drag the
q2a commit onto the
x (master) commit and you will get the desired result:
q2b (quickfix2) | q2a | | q1b (quickfix1) | | | q1b | / x (master) | ...
In SmartGit, there are several places from which you can initiate a rebase:
- Menu and toolbar On the Working tree window, select Branch|Rebase to open the Rebase dialog, where you can select the branch to rebase the HEAD onto, or the branch to rebase onto the HEAD, respectively. Depending on your toolbar settings, you can also open this dialog using the *Rebase toolbar button.
- Branches view In the Branches view, you can right-click on a branch and select Rebase to rebase your current HEAD onto the selected branch.
- Log Graph On the Log graph of the Log window, you can perform a rebase by right-clicking on a commit and selecting Rebase from the context-menu.
- Log Graph In the Log graph of the Log window, you can drag and drop commits or refs and then select to rebase in the occurring dialog after the drop.
Just like a merge, a rebase may fail due to merge conflicts. If that happens, SmartGit will leave the working tree in rebasing state, allowing you to either manually resolve the conflicts or to Abort the rebase.
Core Git rebase conflicts are different to other kinds of merge conflicts, because left and right files are swapped: when rebasing branch
B, Git will first checkout
B, then applies all commits from
If a conflict occurs,
HEAD still points to
B and hence the left file would be the file as it’s present in
