Issues

We use Github Issues to track public bugs and feature requests.

Please search the existing issues to see if any similar issue or feature request has already been filed. You should make sure your issue isn't redundant.

Reporting New Issues

If you open an issue, the more information the better. Such as detailed description, screenshot or video of your problem, logcat or code blocks for your crash.

Branch Management

There are three main branches here:

1. master branch.

   (1). It is the latest (pre-)release branch. We use master for tags, with version number 1.0.0, 1.1.0, 1.2.0...

   (2). Don't submit any PR on master branch.

2. specific version branchs.

   (1).There is a specific version for each Angel version, such as branch-1.0.0, branch-1.1.0. It is our stable developing branch. After full testing, specific version branch will be merged to master branch for the next release.

   (2). You are recommended to submit bugfix or feature PR on specific version branch.

Normal bugfix or feature request should be submitted to specific version branch. After full testing, we will merge them to master branch for the next release.

Make Pull Requests

The code team will monitor all pull request, we run some code check and test on it. After all tests passed, we will accecpt this PR. But it won't merge to master branch at once, which have some delay.

Before submitting a pull request, please make sure the followings are done:

1. Fork the repo and create your branch from master or specific version.
2. Update code or documentation if you have changed APIs.
3. Add the copyright notice to the top of any new files you've added.
4. Check your code lints and checkstyles.
5. Test and test again your code.
6. Now, you can submit your pull request on specific version branch.
