If you are new to Git and GitHub, we recommend to read this page. Otherwise, you may skip it.
Our GitHub workflow is a so called triangular workflow:
The Vitess code is hosted on GitHub (https://github.com/youtube/vitess). This repository is called upstream. You develop and commit your changes in a clone of our upstream repository (shown as local in the image above). Then you push your changes to your forked repository (origin) and send us a pull request. Eventually, we will merge your pull request back into the upstream repository.
Since you should have cloned the repository from your fork, the
should look like this:
$ git remote -v origin firstname.lastname@example.org:<yourname>/vitess.git (fetch) origin email@example.com:<yourname>/vitess.git (push)
To help you keep your fork in sync with the main repo, add an
$ git remote add upstream firstname.lastname@example.org:youtube/vitess.git $ git remote -v origin email@example.com:<yourname>/vitess.git (fetch) origin firstname.lastname@example.org:<yourname>/vitess.git (push) upstream email@example.com:youtube/vitess.git (fetch) upstream firstname.lastname@example.org:youtube/vitess.git (push)
Now to sync your local
master branch, do this:
$ git checkout master (master) $ git pull upstream master
Note: In the example output above we prefixed the prompt with
stress the fact that the command must be run from the branch
You can omit the
upstream master from the
git pull command when you let your
master branch always track the main
youtube/vitess repository. To achieve
this, run this command once:
(master) $ git branch --set-upstream-to=upstream/master
Now the following command syncs your local
master branch as well:
(master) $ git pull
Before you start working on changes, create a topic branch:
$ git checkout master (master) $ git pull (master) $ git checkout -b new-feature (new-feature) $ # You are now in the new-feature branch.
Try to commit small pieces along the way as you finish them, with an explanation of the changes in the commit message. Please see the Code Review page for more guidance.
As you work in a package, you can run just
the unit tests for that package by running
go test from within that package.
When you're ready to test the whole system, run the full test suite with
test from the root of the Git tree.
If you haven't installed all dependencies for
make test, you can rely on the Travis CI test results as well.
These results will be linked on your pull request.
Push your branch to the repository (and set it to track with
(new-feature) $ git push -u origin new-feature
You can omit
-u new-feature parameters from the
command with the following two Git configuration changes:
$ git config remote.pushdefault origin $ git config push.default current
The first setting saves you from typing
origin every time. And with the second
setting, Git assumes that the remote branch on the GitHub side will have the
same name as your local branch.
After this change, you can run
git push without arguments:
(new-feature) $ git push
If you need to make changes in response to the reviewer's comments, just make another commit on your branch and then push it again:
$ git checkout new-feature (new-feature) $ git commit (new-feature) $ git push
That is because a pull request always mirrors all commits from your topic branch which are not in the master branch.
Once your pull request is merged:
git branch -d new-feature)
