Ruff integration roadmap

The entire Ambari project has accumulated a large amount of Python code, which is the result of the collective efforts of multiple contributors to make Ambari better.

During this process, a problem has emerged: everyone has different coding styles, which leads to inconsistencies in the submitted code. This can result in various inconveniences, such as increased understanding costs of the underlying principles and greater difficulty in identifying the root causes of issues. As the codebase grows, these problems become increasingly apparent. Therefore, we are introducing ruff, along with some additional processes, to format the code and alleviate these issues.

What is Ruff?

An extremely fast Python linter and code formatter, written in Rust. Its speed is one of its advantages. More information can be found here: ruff.

Roadmap

• Introduce Ruff into Ambari and preset rules, then manually execute the formatting command.
• ntegrate Ruff checker into Jenkins, checker that fails will block the merge process.
• Integrate pre-commit hooks.
