Workflow

You can follow the workflow to operate development, and you can see Make Your First Contribution if you are a newcomer and need more detailed instructions about workflow.

1. Fork the MatrixOne repository on GitHub. 2. Clone your fork to your local machine with:

git clone [email protected]:<yourname>/matrixone.git

And add MatrixOne repo as a remote repository with:

git remote add upstream https://github.com/matrixorigin/matrixone.git

3. Create a new branch. The branch name is up to you.

git checkout -b topic-branch

4. Commit changes to your own branch locally, add necessary unit tests.

5. Push to a new branch in your own fork.

git push origin main:NEW_BRANCH

6. Go back to GitHub, and submit a pull request in NEW_BRANCH so that we can review your changes. Add some labels if needed, and don't forget to refer to the related issue.

7. Once your PR gets approved, it will be merged sooner. After merging, synchronize your local repository.

git pull --force upstream main:main

8. Synchronized the main branch of your remote repository in Github.

git push --force origin main:main

If you still have some trouble, please refer to GitHub Docs for help.

Code review

When you open a pull request, you can assign some reviewers, or just leave it blank. And you can add some related labels to make it easier to recognize the PR's type/priority/etc. During the review, reviewers would comment on your code snippet, and you can modify the code on your topic branch locally, commit the changes, and push it to GitHub where the new commits would be attached to the PR automatically.
