Contributing¶
Thanks for considering contributing to Fedora Messaging Git Hook, we really appreciate it!
Quickstart:
Look for an existing issue about the bug or feature you’re interested in. If you can’t find an existing issue, create a new one.
Fork the repository on GitHub.
Fix the bug or add the feature, and then write one or more tests which show the bug is fixed or the feature works.
Submit a pull request and wait for a maintainer to review it.
More detailed guidelines to help ensure your submission goes smoothly are below.
Note
If you do not wish to use GitHub, please send patches to infrastructure@lists.fedoraproject.org.
Development Environment¶
Vagrant allows contributors to get quickly up and running with a Fedora Messaging Git Hook development environment by automatically configuring a virtual machine. To get started, first install the Vagrant and Virtualization packages needed, and start the libvirt service:
$ sudo dnf install ansible libvirt vagrant-libvirt vagrant-sshfs vagrant-hostmanager
$ sudo systemctl enable libvirtd
$ sudo systemctl start libvirtd
Check out the code and run vagrant up
:
$ git clone http://github.com/fedora-infra/fedora-messaging-git-hook
$ cd fedora-messaging-git-hook
$ vagrant up
Next, SSH into your newly provisioned development environment:
$ vagrant ssh
Note that the /home/vagrant/fedora-messaging-git-hook
folder contains the source of the
git checkout on your host. Any changes to the files in that directory on the host will be
automatically synced to the VM.
Guidelines¶
Python Support¶
Fedora Messaging Git Hook supports Python 3.6 or greater. This is automatically enforced by the continuous integration (CI) suite.
Code Style¶
We follow the PEP8 style guide for Python. This is automatically enforced by the CI suite.
We are using Black <https://github.com/psf/black> to automatically format the source code. It is also checked in CI. The Black webpage contains instructions to configure your editor to run it on the files you edit.
Handle every possible case, and do so where it makes sense.
Security¶
Remember to keep the code simple enough that it can be easily reviewed for security concerns.
Code that touches security-critical paths must be signed off by two people. People who sign off are agreeing to have reviewed the code thoroughly and thought about edge cases.
Tests¶
The test suites can be run using tox by simply
running tox
from the repository root. All code must have test coverage or
be explicitly marked as not covered using the # pragma: no cover
comment.
This should only be done if there is a good reason to not write tests.
Your pull request should contain tests for your new feature or bug fix. If you’re not certain how to write tests, we will be happy to help you.
Release Notes¶
To add entries to the release notes, create a file in the news
directory in the
source.type
name format, where the source
part of the filename is:
42
when the change is described in issue42
PR42
when the change has been implemented in pull request42
, and there is no associated issueCabcdef
when the change has been implemented in changesetabcdef
, and there is no associated issue or pull request.
And where the extension type
is one of:
security
: for security fixesremoved
: for removed features (this will be a backwards incompatible change)deprecated
: for deprecated featuresadded
: for new featuresfixed
: for bug fixeschanged
: for other changes
The content of the file will end up in the release notes. It should not end
with a .
(full stop).
A preview of the release notes can be generated with towncrier build --draft
.
