Managing code reviews and merge requests in SVN (Subversion) involves a series of steps to ensure that changes are reviewed before they are integrated into the main codebase. Here’s how you can manage them:

  1. Branching Strategy: Develop new features or bug fixes in separate branches. This keeps the main trunk stable and allows for parallel development.

  2. Commit Messages: Encourage clear and concise commit messages that explain the changes made. This aids reviewers in understanding the purpose and impact of the changes.

  3. Code Review Process:

    • Request Review: Developers should request a code review from peers or seniors before merging their changes.
    • Review Tools: Use tools like Review Board, Crucible, or even manual code review processes to examine the changes.
    • Feedback: Reviewers provide feedback, which developers must address before proceeding.

  4. Merge Requests:

    • Create Merge Request: Once the code is reviewed and approved, create a merge request to integrate the changes into the main branch.
    • Automated Testing: Before merging, run automated tests to ensure that the new code does not break existing functionality.

  5. Merging:

    • Manual Merge: In SVN, merging is often done manually using the svn merge command. This allows for careful inspection of conflicts and ensures that only approved changes are merged.
    • Commit Changes: After merging, commit the changes with an appropriate message that references the merge request and any relevant review details.

Example:

  • Developer A works on a new feature in branch feature-A.
  • Developer A completes the feature and requests a code review.
  • Reviewer B examines the changes, suggests improvements, and approves the code.
  • Developer A addresses the feedback and requests a merge into the main trunk.
  • Automated tests pass, and Developer A merges the changes using svn merge.
  • Developer A commits the merge with a message like "Merged feature-A after review".
