Cloning your fork
Clone the repository from your fork:
git clone ssh://firstname.lastname@example.org/<username>/<reponame>.git git clone ssh://email@example.com/JamesClonk/martini.git
Add the upstream repository so that you can pull the latest changes:
git remote add upstream firstname.lastname@example.org:<original-username>/<original-reponame>.git git remote add upstream email@example.com:codegangsta/martini.git
Tracking an existing branch
List all your branches:
git branch -a
To start tracking an already existing branch from origin locally, use the following commands:
git branch <branch> origin/<branch> git branch development origin/development
Working on a topic branch
Always try to avoid working on the master branch. It usually results in merge conflicts and/or update issues. Instead, work on a bug/feature/topic branch whenever possible.
# start from the master branch git checkout master # create a new branch git branch dev/jamesclonk/new_feature/12345 # switch to the new branch git checkout dev/jamesclonk/new_feature/12345 # ...make changes...
Once a fork has been created, it does not automatically track the upstream repository. Follow the steps outlined below to keep the master branch up-to-date.
# pull the latest changes from upstream git fetch upstream git fetch upstream --tags # make sure there are no un-committed changes git stash # make sure we are working on the master branch git checkout master # merge the latest changes git merge upstream/master # push the updates changes to your GitHub fork git push origin master git push origin --tags # return to your bug/feature branch git checkout dev/jamesclonk/new_feature/12345 # rebase this branch onto latest code from master (expect conflicts) git rebase master # ... resolve conflicts # push the rebased branch back to your fork git push origin dev/jamesclonk/new_feature/12345 -f # restore any un-committed changes git stash pop
Note: The git stash steps are optional. It is easier if you commit all changes before attempting a rebase.
Squashing your changes into one revision
Before you submit a pull request, rebase all your changes onto a single commit. This makes it easier to review and also makes reverting the code easier in case of any build breakages.
git rebase -i master # ... squash commits ...
