NAME
|
|
----
|
|
git-rebase - Forward-port local commits to the updated upstream head
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-rebase' [-v] [--merge] [--onto <newbase>] <upstream> [<branch>]
|
|
|
|
'git-rebase' --continue | --skip | --abort
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
git-rebase replaces <branch> with a new branch of the same name. When
|
|
the --onto option is provided the new branch starts out with a HEAD equal
|
|
to <newbase>, otherwise it is equal to <upstream>. It then attempts to
|
|
create a new commit for each commit from the original <branch> that does
|
|
not exist in the <upstream> branch.
|
|
|
|
It is possible that a merge failure will prevent this process from being
|
|
completely automatic. You will have to resolve any such merge failure
|
|
and run `git rebase --continue`. Another option is to bypass the commit
|
|
that caused the merge failure with `git rebase --skip`. To restore the
|
|
original <branch> and remove the .dotest working files, use the command
|
|
`git rebase --abort` instead.
|
|
|
|
Note that if <branch> is not specified on the command line, the currently
|
|
checked out branch is used.
|
|
|
|
Assume the following history exists and the current branch is "topic":
|
|
|
|
------------
|
|
A---B---C topic
|
|
/
|
|
D---E---F---G master
|
|
------------
|
|
|
|
From this point, the result of either of the following commands:
|
|
|
|
|
|
git-rebase master
|
|
git-rebase master topic
|
|
|
|
would be:
|
|
|
|
------------
|
|
A'--B'--C' topic
|
|
/
|
|
D---E---F---G master
|
|
------------
|
|
|
|
The latter form is just a short-hand of `git checkout topic`
|
|
followed by `git rebase master`.
|
|
|
|
Here is how you would transplant a topic branch based on one
|
|
branch to another, to pretend that you forked the topic branch
|
|
from the latter branch, using `rebase --onto`.
|
|
|
|
First let's assume your 'topic' is based on branch 'next'.
|
|
For example feature developed in 'topic' depends on some
|
|
functionality which is found in 'next'.
|
|
|
|
------------
|
|
o---o---o---o---o master
|
|
\
|
|
o---o---o---o---o next
|
|
\
|
|
o---o---o topic
|
|
------------
|
|
|
|
We would want to make 'topic' forked from branch 'master',
|
|
for example because the functionality 'topic' branch depend on
|
|
got merged into more stable 'master' branch, like this:
|
|
|
|
------------
|
|
o---o---o---o---o master
|
|
| \
|
|
| o'--o'--o' topic
|
|
\
|
|
o---o---o---o---o next
|
|
------------
|
|
|
|
We can get this using the following command:
|
|
|
|
git-rebase --onto master next topic
|
|
|
|
|
|
Another example of --onto option is to rebase part of a
|
|
branch. If we have the following situation:
|
|
|
|
------------
|
|
H---I---J topicB
|
|
/
|
|
E---F---G topicA
|
|
/
|
|
A---B---C---D master
|
|
------------
|
|
|
|
then the command
|
|
|
|
git-rebase --onto master topicA topicB
|
|
|
|
would result in:
|
|
|
|
------------
|
|
H'--I'--J' topicB
|
|
/
|
|
| E---F---G topicA
|
|
|/
|
|
A---B---C---D master
|
|
------------
|
|
|
|
This is useful when topicB does not depend on topicA.
|
|
|
|
In case of conflict, git-rebase will stop at the first problematic commit
|
|
and leave conflict markers in the tree. You can use git diff to locate
|
|
the markers (<<<<<<) and make edits to resolve the conflict. For each
|
|
file you edit, you need to tell git that the conflict has been resolved,
|
|
typically this would be done with
|
|
|
|
|
|
git update-index <filename>
|
|
|
|
|
|
After resolving the conflict manually and updating the index with the
|
|
desired resolution, you can continue the rebasing process with
|
|
|
|
|
|
git rebase --continue
|
|
|
|
|
|
Alternatively, you can undo the git-rebase with
|
|
|
|
|
|
git rebase --abort
|
|
|
|
OPTIONS
|
|
-------
|
|
<newbase>::
|
|
Starting point at which to create the new commits. If the
|
|
--onto option is not specified, the starting point is
|
|
<upstream>.
|
|
|
|
<upstream>::
|
|
Upstream branch to compare against.
|
|
|
|
<branch>::
|
|
Working branch; defaults to HEAD.
|
|
|
|
--continue::
|
|
Restart the rebasing process after having resolved a merge conflict.
|
|
|
|
--abort::
|
|
Restore the original branch and abort the rebase operation.
|
|
|
|
--skip::
|
|
Restart the rebasing process by skipping the current patch.
|
|
|
|
--merge::
|
|
Use merging strategies to rebase. When the recursive (default) merge
|
|
strategy is used, this allows rebase to be aware of renames on the
|
|
upstream side.
|
|
|
|
-s <strategy>, \--strategy=<strategy>::
|
|
Use the given merge strategy; can be supplied more than
|
|
once to specify them in the order they should be tried.
|
|
If there is no `-s` option, a built-in list of strategies
|
|
is used instead (`git-merge-recursive` when merging a single
|
|
head, `git-merge-octopus` otherwise). This implies --merge.
|
|
|
|
-v, \--verbose::
|
|
Display a diffstat of what changed upstream since the last rebase.

NOTES
|
|
-----
|
|
When you rebase a branch, you are changing its history in a way that
|
|
will cause problems for anyone who already has a copy of the branch
|
|
in their repository and tries to pull updates from you. You should
|
|
understand the implications of using 'git rebase' on a repository that
|
|
you share.
|
|
|
|
When the git rebase command is run, it will first execute a "pre-rebase"
|
|
hook if one exists. You can use this hook to do sanity checks and
|
|
reject the rebase if it isn't appropriate. Please see the template
|
|
pre-rebase hook script for an example.
|
|
|
|
You must be in the top directory of your project to start (or continue)
|
|
a rebase. Upon completion, <branch> will be the current branch.
