Dolphinscheduler: How to contribute code?

[boandai]

• First from the remote repository https://github.com/apache/incubator-dolphinscheduler.git fork code to your own 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.

• Clone your own warehouse to your local

  git clone https://github.com/apache/incubator-dolphinscheduler.git

• Add remote repository address, named upstream

  git remote add upstream https://github.com/apache/incubator-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 such as 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 dev1.0

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

git commit -m 'test commit'
git push

• Submit changes to the remote repository

• On the github page, click on the new pull request.

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

* Next, the Committers is responsible for **merging** to complete the pull request --- * 首先从远端仓库*https://github.com/apache/incubator-dolphinscheduler.git* fork一份代码到自己的仓库中 * 远端仓库中目前有三个分支： * master 正常交付分支 发布稳定版本以后，将稳定版本分支的代码合并到master上。 * dev 日常开发分支 日常dev开发分支，新提交的代码都可以pull request到这个分支上。 * branch-1.0.0 发布版本分支 发布版本分支，后续会有2.0...等版本分支，版本分支只修改bug，不增加新功能。 * 把自己仓库clone到本地 `git clone https://github.com/apache/incubator-dolphinscheduler.git` * 添加远端仓库地址，命名为upstream ` git remote add upstream https://github.com/apache/incubator-dolphinscheduler.git ` * 查看仓库： ` git remote -v` > 此时会有两个仓库：origin(自己的仓库)和upstream（远端仓库） * 获取/更新远端仓库代码（已经是最新代码，就跳过） `git fetch upstream ` * 同步远端仓库代码到本地仓库

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

如果远端分支有新加的分支比如`dev-1.0`,需要同步这个分支到本地仓库

git checkout -b dev-1.0 upstream/dev-1.0
git push --set-upstream origin dev1.0

* 在本地修改代码以后，提交到自己仓库： `git commit -m 'test commit'` `git push` * 将修改提交到远端仓库 * 在github页面，点击New pull request.

* 选择修改完的本地分支和要合并过去的分支，Create pull request.

• 接下来由管理员负责将Merge完成此次pull request

项目似乎还没有配置持续集成,这样容易在合并提交时引入异常和不可用风险,建议配置
https://travis-ci.org/
来引入持续集成

如何同时提交多个PR，我是在IDEA操作的
1、选中upstream/dev点击Checkout AS...
2、命名为你当次提交PR的功能名称，例如我的是添加http组件：dev-add-http-components
3、然后有两种场景：
一、你在当前分支开发代码：
（1）开发完代码，然后Commit and Push，值得注意的是：Push的时候需要改提交的分支为origin/dev-add-http-components
（2）最后在github页面，点击New pull request，选择修改完的本地分支和要合并过去的分支，Create pull request，就完成提交 PR了。

二、你在其他分支开发完代码：
（1）打开Version Control - Log ，选择其它分支提交的代码记录，点击Cherry-Pick,更新到本地，然后Commit and Push，值得注意的是：Push的时候需要改提交的分支为origin/dev-add-http-components
（2）最后在github页面，点击New pull request，选择修改完的本地分支和要合并过去的分支，Create pull request，就完成提交 PR了。
