The text provides a comprehensive exploration of stacked pull requests (PRs) in software development, offering insights and strategies for effectively organizing and managing them. It emphasizes the importance of understanding a codebase's architecture and the interactions between its components, using examples like layered architecture to illustrate dependency management. The author discusses various models for splitting stacks, such as functional component-based stacks, iterative improvement stacks, and separating refactoring from bug fixes to enhance review clarity. Additionally, it highlights the benefits of isolating version bumps and generated code in separate PRs to minimize review distractions and suggests handling risky changes by creating distinct PRs within the stack to facilitate easy reversion if necessary. Key takeaways include stacking only related changes, merging frequently to catch integration issues early, and regularly restacking on the main branch to avoid conflicts, ultimately aiming to optimize the development process.
