This page is for maintainers — those of us who merge our own or other peoples’ changes into the upstream repository.
Being as how you’re a maintainer, you are completely on top of the basic stuff in Development workflow.
The instructions in Linking your repository to the upstream repo add a remote that has read-only access to the upstream repo. Being a maintainer, you’ve got read-write access.
It’s good to have your upstream remote have a scary name, to remind you that it’s a read-write remote:
git remote add upstream-rw firstname.lastname@example.org:nipy/dipy.git git fetch upstream-rw
Let’s say you have some changes that need to go into trunk
The changes are in some branch that you are currently on. For example, you are looking at someone’s changes like this:
git remote add someone git://github.com/someone/dipy.git git fetch someone git branch cool-feature --track someone/cool-feature git checkout cool-feature
So now you are on the branch with the changes to be incorporated upstream. The rest of this section assumes you are on this branch.
If there are only a few commits, consider rebasing to upstream:
# Fetch upstream changes git fetch upstream-rw # rebase git rebase upstream-rw/master
Remember that, if you do a rebase, and push that, you’ll have to close any github pull requests manually, because github will not be able to detect the changes have already been merged.
If there are a longer series of related commits, consider a merge instead:
git fetch upstream-rw git merge --no-ff upstream-rw/master
The merge will be detected by github, and should close any related pull requests automatically.
--no-ff above. This forces git to make a merge commit, rather than
doing a fast-forward, so that these set of commits branch off trunk then rejoin
the main history with a merge, rather than appearing to have been made directly
on top of trunk.
Now, in either case, you should check that the history is sensible and you have the right commits:
git log --oneline --graph git log -p upstream-rw/master..
The first line above just shows the history in a compact way, with a text
representation of the history graph. The second line shows the log of commits
excluding those that can be reached from trunk (
including those that can be reached from current HEAD (implied with the
at the end). So, it shows the commits unique to this branch compared to trunk.
-p option shows the diff for these commits in patch form.
