Development

Start by forking the dolphinscheduler GitHub repository, make changes in a branch and then send a pull request.

Set up your dolphinscheduler GitHub Repository

There are three branches in the remote repository currently:

• master : normal delivery branch. After the stable version is released, the code for the stable version branch is merged into the master branch.

• dev : daily development branch. The daily development branch, the newly submitted code can pull requests to this branch.

• x.x.x-release : the stable release version.

So, you should fork the dev branch.

After forking the dolphinscheduler upstream source repository to your personal repository, you can set your personal development environment.

$ cd <your work direcotry>
$ git clone < your personal forked dolphinscheduler repo>
$ cd dolphinscheduler

Set git remote as upstream

Add remote repository address, named upstream

git remote add upstream https://github.com/apache/dolphinscheduler.git

View repository:

git remote -v

There will be two repositories at this time: origin (your own warehouse) and upstream (remote repository)

Get/update remote repository code (already the latest code, skip it).

git fetch upstream

Synchronize remote repository code to local repository

git checkout origin/dev
git merge --no-ff upstream/dev

If remote branch has a new branch DEV-1.0, you need to synchronize this branch to the local repository.

git checkout -b dev-1.0 upstream/dev-1.0
git push --set-upstream origin dev-1.0

Create your feature branch

Before making code changes, make sure you create a separate branch for them.

$ git checkout -b <your-feature>

Commit changes

After modifying the code locally, submit it to your own repository:

git commit -m 'information about your feature'

Push to the branch

Push your locally committed changes to the remote origin (your fork).

$ git push origin <your-feature>

Create a pull request

After submitting changes to your remote repository, you should click on the new pull request On the following github page.

Select the modified local branch and the branch to merge past to create a pull request.

Next, the administrator is responsible for merging to complete the pull request.
