| <h1>Engineering Principles and Practices</h1> |
| |
| <p>This document is an attempt to capture a shared set of values for the project. |
| Many companies rely on Mesos as a foundational layer of their software |
| infrastructure and it is imperative that we ship <strong>robust, high quality</strong> |
| code. We aim to foster a culture where we can trust and rely upon the work of |
| the community.</p> |
| |
| <p>The following are some of the aspirational principles and practices that |
| guide us:</p> |
| |
| <ol> |
| <li>We value <strong>craftsmanship</strong>: code should be easy to read and understand, |
| should be written with high attention to detail, and should be consistent |
| in its style. Code is written for humans to read and maintain!</li> |
| <li>We value <strong>resiliency</strong>: our system must be highly-available, stable, and |
| backwards-compatible. We must consider the implications of failures.</li> |
| <li>We value <strong>accountability</strong>: we own and support our software, and are |
| accountable for improving it, fixing issues, and learning from our mistakes.</li> |
| <li>We value <strong>design and code review</strong>: review helps us maintain a high |
| quality system architecture and high quality code, it also helps us mentor |
| new contributors, learn to collaborate more effectively, and reduce the |
| amount of mistakes.</li> |
| <li>We value <strong>automated testing</strong>: automated testing allows us to iterate and |
| refactor in our large codebase, while verifying correctness and preventing |
| regression.</li> |
| <li>We value <strong>benchmarking</strong>: benchmarking allows us to identify the right |
| locations to target performance improvements. It also allows us to iterate |
| and refactor in our large codebase, while observing the performance |
| implications.</li> |
| </ol> |
