Contributing¶

Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given.

You can contribute in many ways:

Types of Contributions¶

Report Bugs¶

Report bugs at bugzilla.

If you are reporting a bug, please include:

Your operating system name and version.
Any details about your local setup that might be helpful in troubleshooting.
Detailed steps to reproduce the bug.

Fix Bugs¶

Look through the GitHub issues for bugs. Anything tagged with “bug” and “help wanted” is open to whoever wants to implement it.

Implement Features¶

Look through the GitHub issues for features. Anything tagged with “enhancement” and “help wanted” is open to whoever wants to implement it.

Write Documentation¶

glean_parser could always use more documentation, whether as part of the official glean_parser docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback¶

The best way to send feedback is to file an issue at TODO

If you are proposing a feature:

Explain in detail how it would work.
Keep the scope as narrow as possible, to make it easier to implement.
Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!¶

Ready to contribute? Here’s how to set up glean_parser for local development.

Fork the glean_parser repo on GitHub.

Clone your fork locally:

$ git clone git@github.com:your_name_here/glean_parser.git

Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:
```
$ mkvirtualenv glean_parser
$ cd glean_parser/
$ pip install --editable .
```
Create a branch for local development:
```
$ git checkout -b name-of-your-bugfix-or-feature
```
Now you can make your changes locally.
To test your changes to glean_parser:

Install the testing dependencies:
```
$ pip install -r requirements_dev.txt
```
Optionally, if you want to ensure that the generated Kotlin code lints correctly, install a Java SDK, and then run:
```
$ make install-kotlin-linters
```
Then make sure that all lints and tests are passing:
```
$ make lint
$ make test
```

Commit your changes and push your branch to GitHub:

$ git add .
$ git commit -m "Your detailed description of your changes."
$ git push origin name-of-your-bugfix-or-feature

Submit a pull request through the GitHub website.

Pull Request Guidelines¶

Before you submit a pull request, check that it meets these guidelines:

The pull request should include tests.
If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and describe public-facing features in the docs.
The pull request should work for Python 3.8+ (The CI system will take care of testing all of these Python versions).
The pull request should update the changelog in CHANGELOG.md.

Tips¶

To run a subset of tests:

$ py.test tests.test_glean_parser

Deploying¶

A reminder for the maintainers on how to deploy.

Ask around if there are any PRs folks want to get into your release.
Get a clean main branch with all of the changes from upstream:

$ git checkout main
$ git fetch upstream
$ git rebase upstream/main

Update the header with the new version and date in CHANGELOG.md.
(By using the setuptools-scm package, there is no need to update the version anywhere else).
Make sure all your changes are committed.
Push the changes upstream. (Normally pushing directly without review is frowned upon, but the main branch is protected from force pushes and release tagging requires the same permissions as pushing to main):
```
$ git push upstream main
```
Wait for continuous integration to pass on main.
Make the release on GitHub using this link
Both the tag and the release title should be in the form vX.Y.Z.
Copy and paste the relevant part of the CHANGELOG.md file into the description.
Tagging the release will trigger a CI workflow which will build the distribution of glean_parser and publish it to PyPI.
- The continuous integration system will then automatically deploy to PyPI.
Post a message to #glean:mozilla.org announcing the new release.
- Include a copy of the release-specific changelog if you want to be fancy.
