Git workflow for Yii contributors
So you want to contribute to Yii? Great! But to increase the chances of your changes being accepted quickly, please follow the following steps (the first 2 steps only need to be done the first time you contribute). If you are new to git and github, you might want to first check out github help, learn git or learn something about git internal data model.
1. Fork the Yii repository on github and clone your fork to your development environment
git clone [email protected]:YOUR-GITHUB-USERNAME/yii.git
If you have trouble setting up GIT with GitHub in Linux, or are getting errors like "Permission Denied (publickey)", then you must setup your GIT installation to work with GitHub
Change to the directory where you cloned Yii, normally, "yii". Then enter the following command:
git remote add upstream git://github.com/yiisoft/yii.git
All new features and bug fixes should have an associated issue to provide a single point of reference for discussion and documentation. Take a few minutes to look through the existing issue list for one that matches the contribution you intend to make. If you find one already on the issue list, then please leave a comment on that issue indicating you intend to work on that item. If you do not find an existing issue matching what you intend to work on, please open a new issue for your item. This will allow the team to review your suggestion, and provide appropriate feedback along the way.
For small changes or documentation issues, you don't need to create an issue, a pull request is enough in this case.
git fetch upstream
You should start at this point for every new contribution to make sure you are working on the latest code.
That's very important since you will not be able to submit more than one pull request from your account if you'll use master.
Each separate bug fix or change should go in its own branch. Branch names should be descriptive and start with the number of the issue that your code relates to. If you aren't fixing any particular issue, just skip number. For example:
git checkout upstream/master git checkout -b 999-name-of-your-branch-goes-here
Make sure it works :)
Unit tests are always welcome. Tested and well covered code greatly simplifies the task of checking your contributions. Failing unit tests as issue description are also accepted.
Edit the CHANGELOG file to include your change, you should insert this at the top of the file under the "Work in progress" heading, the line in the change log should look like one of the following:
Bug #999: a description of the bug fix (Your Name)
Enh #999: a description of the enhancement (Your Name)
#999 is the issue number that the Bug or Enh is referring to.
The changelog should be grouped by type (Bug,Enh) and ordered by issue number.
For very small fixes, e.g. typos and documentation changes, there is no need to update the CHANGELOG.
add the files/changes you want to commit to the staging area with
git add path/to/my/file.php
You can use the -p option to select the changes you want to have in your commit.
Commit your changes with a descriptive commit message. Make sure to mention the ticket number with #XXX so github will automatically link your commit with the ticket:
git commit -m "A brief description of this change which fixes #42 goes here"
git pull upstream master
This ensures you have the latest code in your branch before you open your pull request. If there are any merge conflicts, you should fix them now and commit the changes again. This ensures that it's easy for the Yii team to merge your changes with one click.
git push -u origin 999-name-of-your-branch-goes-here
The -u parameter ensures that your branch will now automatically push and pull from the github branch. That means if you type git push the next time it will know where to push to.
11. Open a pull request against upstream.
Go to your repository on github and click "Pull Request", choose your branch on the right and enter some more details in the comment box. To link the pull request to the issue put anywhere in the pull comment #999 where 999 is the issue number.
Note that each pull-request should fix a single change.
Someone will review your code, and you might be asked to make some changes, if so go to step #6 (you don't need to open another pull request if your current one is still open). If your code is accepted it will be merged into the main branch and become part of the next Yii release. If not, don't be disheartened, different people need different features and Yii can't be everything to everyone, your code will still be available on github as a reference for people who need it.
After your code was either accepted or declined you can delete branches you've worked with from your local repository and origin.
git checkout master git branch -D 999-name-of-your-branch-goes-here git push origin --delete 999-name-of-your-branch-goes-here
To detect regressions early every merge to the Yii codebase on github will be picked up by Travis CI for an automated testrun. As core team doesn't wish to overtax this service, [ci skip] will be included to the merge description if the pull request:
- affect javascript, css or image files only,
- updates the documentation,
- modify fixed strings only (e.g. translation updates)
Doing so will save travis from commencing testruns on changes that are not covered by tests in the first place.
git clone [email protected]:YOUR-GITHUB-USERNAME/yii.git git remote add upstream git://github.com/yiisoft/yii.git
git fetch upstream git checkout upstream/master git checkout -b 999-name-of-your-branch-goes-here /* do your magic, update changelog if needed */ git add path/to/my/file.php git commit -m "A brief description of this change which fixes #42 goes here" git pull upstream master git push -u origin 999-name-of-your-branch-goes-here
