Navigating the Patch Submission Processes in Open Source Communities: Linux Kernel & Python
In the open-source world, contributing to established projects like the Linux kernel or the Python programming language can be a rewarding experience. However, the journey from having a great idea to getting your code accepted can be quite different from one community to another. In this blog post, I'll try to introduce and explain the patch submission process in two prominent open-source communities – Linux and Python – while highlighting the advantages and disadvantages of each approach.
Linux Kernel:
The Linux Patch Submission Process:
- Development:
Like most open-source projects, contributors begin by developing their
code changes.
- Version
Control: Developers work in their own branches, forking the Linux
kernel repository in Git.
- Patch
Submission: Patches are submitted through the Linux kernel's mailing
list as plain text email messages.
- Mailing
List: The "linux-kernel" mailing list is the primary channel
for patch submission and review.
- Review
Process: The patch undergoes extensive review from a large pool of
experienced developers, maintainers, and security experts.
- Discussion
and Feedback: Reviewers provide feedback, engage in technical
discussions, and suggest improvements on the mailing list.
- Maintainers:
Area-specific maintainers have the authority to accept or reject patches.
- Integration:
Accepted patches are integrated into the Linux kernel source code.
- Testing
and Release: Rigorous testing and continuous integration ensure
stability before official releases.
Advantages of the Linux Kernel Approach:
- Extensive
Review: The Linux community boasts a large and experienced developer
base, leading to thorough reviews.
- Security
Focus: Critical patches, such as those addressing security
vulnerabilities, are rapidly reviewed and integrated.
- Collaboration:
The mailing list format encourages discussion, knowledge sharing, and
community collaboration.
Disadvantages of the Linux Kernel Approach:
- Complex
Process: The extensive review process can be daunting, especially for
newcomers.
- High
Volume: The high volume of patches and discussions can make it
challenging to gain attention for your patch.
Prerequisite to submitting a patch to the Linux Kernel
community:
- Learn
Git and understand the kernel's development model.
- Familiarize
yourself with mailing list etiquette.
- Prepare
for constructive criticism and discussion.
Python:
The Python Patch Submission Process:
- Development:
Contributors create and develop their code changes in Python's GitHub
repository.
- Pull
Requests: Patches are submitted as Pull Requests (PRs) on GitHub.
- Review
Process: PRs are reviewed by the Python community, including core
developers and maintainers.
- Discussion
and Feedback: Reviewers provide feedback and engage in discussions
directly within the PR.
- Maintainers:
Core developers and maintainers are responsible for accepting or rejecting
PRs.
- Integration:
Accepted PRs are merged into the Python source code on GitHub.
- Testing
and Release: Testing and integration continue, leading to official
releases.
Advantages of the Python Approach:
- GitHub
Integration: GitHub's user-friendly interface simplifies the
contribution process.
- Streamlined
Discussion: Discussion and feedback occur directly within the PR,
promoting transparency and ease of use.
- Community
Engagement: The Python community encourages active participation from
newcomers.
Disadvantages of the Python Approach:
- GitHub-Centric:
The process may seem GitHub-centric, potentially alienating those not
familiar with the platform.
- Less
Formal Review: The review process might be perceived as less formal
than the mailing list format.
Prerequisite to submit a patch to the Python community:
- Create
a GitHub account and understand Git.
- Familiarize
yourself with the Python development workflow on GitHub.
- Prepare
for a more interactive and GitHub-centered review process.
Personal Observation:
In the Linux Kernel community, I observed a rapid response
to critical security patches, thanks to the vast pool of reviewers. The
thoroughness of the review process ensures code quality, but it can be
intimidating for newcomers. In contrast, I found the Python community more
accessible, with discussions happening directly on GitHub. The user-friendly
platform simplifies contribution but might appear less formal.
The choice between these communities ultimately depends on
your comfort level with their respective workflows, your project's scope, and
your openness to constructive feedback. Regardless of the path you choose,
contributing to open source projects is a valuable learning experience that can
help you grow as a developer and make a meaningful impact on these widely used
software projects.
