Mastering SVN: 10 Essential Practices for Reliable Code Collaboration

1. Upload Code Regularly

Programs must be compiled successfully and uploaded to SVN regularly, preferably multiple times a day, with the final upload before leaving work and updating the latest version each morning.

The workflow is update → compile/run → upload; never upload uncompiled code to avoid conflicts.

Principle: never upload erroneous code; frequent uploads minimize loss and allow the boss to see daily progress.

2. Resolve Solution Conflicts

When adding, deleting, or renaming pages, first update the entire solution, then perform the changes, and upload immediately to prevent conflicts.

What is a solution conflict?

The .csproj file defines the C# project for tools like Visual Studio and MSBuild; conflicts arise when multiple developers modify it simultaneously.

Understanding .csproj helps avoid version conflicts when modifying pages or classes.

3. Add to Ignore List

The following files should not be committed to SVN and must be added to the ignore list:

3.1 Solution .suo files

.suo stores user‑specific solution options such as layout, breakpoints, and window states; it can be deleted if corrupted and will be regenerated.

3.2 Bin and obj folders

bin contains final compiled binaries; obj holds intermediate compilation files. These are generated locally and should be excluded from commits.

These habits improve collaborative development.

4. Update Before Commit

Always update to the latest version before committing; after a successful compile and test, commit cautiously. Resolve any merge conflicts with the original developer before testing again.

5. Commit Frequently

Keep commit intervals short, ideally a few hours, committing after each UI change, small feature, or bug fix.

6. Never Commit Code That Fails to Compile

Ensure code compiles locally before committing; consider third‑party libraries that other team members may lack.

7. Write Clear Commit Messages

Clear, descriptive commit messages help the team track progress and locate issues.

8. Avoid Committing Auto‑Generated Files

Do not commit files such as .classpath, Thumbs.db, .obj, .class, etc., which are generated locally and can cause conflicts.

9. Do Not Commit Code You Do Not Understand

Only commit code you fully understand; unknown code can become a hidden quality risk.

10. Use Locking Sparingly

Lock files only when necessary (e.g., non‑mergeable binary files) to avoid blocking teammates.
