Code Repository

A code repository is more than just a place to store code—it’s the foundation of effective, modular, and scalable software development. In Machanism, a well-organized repository is critical for managing reusable modular components (bricks) and enabling seamless collaboration as systems grow in size and complexity. Proper repository management ensures modularity, scalability, reusability, and independent development of components.

In this section, we will explore the strategies behind repository management for Seed Projects and non-seed projects, and why tools like SVN and Git are essential for supporting Machanism’s philosophy of Divide and Use.

Requirements for Repositories in Machanism

To effectively manage modular projects, the repository must:

  1. Support parent-child relationships: Parent modules should define and manage the structure and dependencies of their sub-modules (artifacts), ensuring logical organization.
  2. Enable scalability: Seamlessly accommodate the growth of sub-modules and their integration into larger systems without structural inefficiencies.
  3. Encourage independent sub-module development: Allow developers to checkout, modify, and manage specific sub-modules independently of the entire repository.
  4. Provide flexibility: Adapt to diverse workflows, ranging from centralized Seed Projects to lightweight non-seed components.

These principles ensure efficient management while preserving the ability to scale and evolve modular systems in a clean, maintainable manner.

Why SVN for Seed Projects?

Seed Projects, the backbone of Machanism’s modular design, demand a repository that handles hierarchical relationships and strict dependency management, while ensuring efficiency across teams. SVN (Subversion) is the ideal choice for these projects due to its native support for managing complex architectures.

Reasons Why SVN is Optimal

  1. Parent and Artifact Sub-Modules
    SVN excels at supporting parent-child hierarchies, where parent modules organize and enforce global settings for sub-modules (artifacts). This ensures modular systems at scale remain highly structured and manageable.

  2. Centralized Version Control
    SVN provides a single source of truth, ensuring consistent alignment between parent and sub-modules. This centralized control is essential for maintaining compatibility between Core logic and artifacts in Seed Projects.

  3. Independent Sub-Module Development
    SVN allows developers to checkout and work on individual sub-modules without downloading the entire repository. For instance, a developer can focus exclusively on a Shipping module without interacting with unrelated components like payment or customer management. This flexibility supports efficient collaboration and reduces overhead.

  4. Performance for Deep Hierarchies
    Seed Projects often involve large, interdependent modules. SVN’s ability to efficiently handle branching and tagging simplifies workflows while managing deep hierarchies effectively.

In essence, SVN supports modular development with structured relationships, centralized control, and independent workflows, enhancing the Divide and Use philosophy.

Prefer Working with Git? Use git-svn

To bridge the gap between Git workflows and the modular structure of SVN, developers can use git-svn. This allows Git operations (commits, branching, merging) to remain compatible with the central SVN repository.

Example: Cloning a Subproject Using git-svn

To clone a specific subproject with git-svn, use the following command:

$ git svn clone module_scm_url
  • module_scm_url refers to the location of the subproject you want to clone, which you can find on the Source Code Management page.

This approach combines the best of both worlds: developers can work with Git locally while adhering to the structure provided by SVN.

Why Git for Non-Seed Projects?

Non-seed projects, often smaller or standalone components such as front-end applications or microservices, don’t require strict hierarchical management. Instead, they thrive with tools that prioritize flexibility, independence, and lightweight version control. Git is the ideal choice for these cases.

Reasons Why Git is Ideal

  1. Distributed Version Control
    Git’s distributed nature allows developers to work locally with branching, commit histories, and merging workflows, without relying on a centralized server. This independence supports rapid iteration and experimentation, ideal for front-end interfaces or standalone utilities.

  2. Integration with CI/CD Pipelines
    Git seamlessly integrates with modern CI/CD tools like GitHub Actions, GitLab CI/CD, and Jenkins, enabling automation of testing, building, and deployment. This ensures fast, reliable delivery for agile, iterative projects.

  3. Lightweight and Flexible
    Non-seed projects often don’t follow strict parent-child hierarchies. Git’s ability to adapt to loosely coupled systems allows for fast prototyping and flexibility, making it an excellent choice where agility and innovation are key.

In short, Git’s lightweight mechanics, distributed workflows, and automation compatibility make it a perfect fit for non-seed projects that require speed and independence.
