What is Subversion (SVN) and TortoiseSVN?

Subversion (SVN) is a centralized version control system that stores the history of files and directories on a central server (the repository). Users check out working copies, make changes locally, and commit those changes back to the repository. SVN tracks revisions, supports branching and merging, and provides history and rollback capabilities.

TortoiseSVN is a Windows shell extension that integrates SVN operations directly into File Explorer. Rather than a separate command-line client, you use context menus and graphical dialogs to perform version-control tasks, making SVN accessible to users who prefer a GUI.

Key fact: TortoiseSVN is a GUI client for the Subversion version control system that integrates into Windows Explorer.

Installing TortoiseSVN

  1. Download the installer from the official site (choose the correct 32-bit or 64-bit build for your OS).
  2. Run the installer and follow the prompts. A reboot may be required to finish shell integration.
  3. Optional: Install a compatible SVN server (such as VisualSVN Server) or ensure you have access to a remote SVN repository.

After installation, right-clicking in File Explorer will show TortoiseSVN menu options (e.g., Checkout, Commit, Update).

Basic Concepts and Terminology

  • Repository: Central storage for all files, history, branches, and tags.
  • Working copy: A local snapshot of a repository path you can edit.
  • Revision: A numbered state of the repository after each commit.
  • Commit: Save local changes to the repository as a new revision.
  • Update: Pull changes from the repository into your working copy.
  • Conflict: When local edits collide with changes from the repository and require manual resolution.
  • Branch: A diverging line of development (often created for features or releases).
  • Tag: A snapshot of the repository at a specific point (commonly used for released versions).

Creating and Checking Out a Repository

If you have server access or a hosted SVN service, you’ll be given a repository URL. To create a new repository locally or on a server:

  • Use a server product (e.g., VisualSVN Server on Windows) or svnadmin on the host machine.
  • Structure your repository with common top-level folders: /trunk, /branches, /tags.

To check out (create a working copy):

  1. In File Explorer, create or choose an empty folder.
  2. Right-click → TortoiseSVN → Checkout.
  3. Enter the Repository URL and target folder, choose revision (usually HEAD), and click OK.

Typical Workflow (Day-to-Day)

  1. Update: Right-click working folder → TortoiseSVN → Update. This brings your working copy up to date with repository changes.
  2. Modify files: Edit code or documents in your editor.
  3. Check status: Right-click → TortoiseSVN → Check for modifications. This shows changed files and their status.
  4. Resolve conflicts (if any): TortoiseSVN marks conflicts and offers tools like the TortoiseMerge visual diff/merge tool.
  5. Commit: Right-click → TortoiseSVN → Commit. Write a clear log message describing the changes and press OK.

Good commit messages and small, focused commits make history easier to understand.

Branching and Tagging with TortoiseSVN

Branching and tagging in SVN are implemented as directory copies—cheap and fast.

To create a branch or tag:

  1. Right-click your working copy or repository-browser item → TortoiseSVN → Branch/Tag.
  2. Enter the target URL (e.g., /branches/feature-x or /tags/release-1.0).
  3. Optionally choose a revision to copy (HEAD by default) and add a log message.
  4. Click OK to create the branch or tag on the server.

To switch your working copy to a branch: Right-click → TortoiseSVN → Switch and enter the branch URL.

Merging Changes

Merging combines changes from one branch into another (e.g., merging a feature branch into trunk).

  1. In the working copy of the target branch, right-click → TortoiseSVN → Merge.
  2. Choose the appropriate merge type (e.g., “Merge a range of revisions” or “Reintegrate a branch”).
  3. Enter the source URL and revision ranges to merge.
  4. Preview, perform the merge, resolve conflicts, then commit the result.

Keep merges frequent and test after merging to reduce complexity.

Using the Repository Browser

TortoiseSVN’s Repo-browser lets you explore the repository without checking out files.

  • Right-click in Explorer → TortoiseSVN → Repo-browser.
  • Enter the repo URL to view folders, history, and file contents.
  • You can copy, delete, move, or create folders directly in the repository from the browser.

Ignoring Files

To prevent committing generated files (build artifacts, IDE settings), add them to svn:ignore:

  1. Right-click the folder containing the files → TortoiseSVN → Properties → New → svn:ignore.
  2. Add patterns (e.g., bin, *.log, .vs) and save.
  3. Commit the property change so the ignore rules are stored in the repository.

Note: svn:ignore works on directory-level patterns; already-versioned files must be svn-remove’d before ignores take effect.

Conflict Resolution

When SVN can’t automatically reconcile changes, conflicts occur. TortoiseSVN helps:

  • Conflicts appear in status dialogs and with special file markers (.mine, .rOLD, .rNEW).
  • Open TortoiseMerge (right-click conflicting file → Edit conflicts) to compare and merge versions visually.
  • After resolving, mark the conflict as resolved (TortoiseSVN → Resolved) and commit.

Useful TortoiseSVN Tools

  • TortoiseMerge: Visual diff and merge tool for resolving conflicts and reviewing changes.
  • Repo-browser: Inspect and manipulate repository contents.
  • Check for modifications: See local changes, property changes, and out-of-date files.
  • Revision Graph: Visualize branch/merge history.
  • Log messages dialog: View history, annotate (blame), and revert to earlier revisions.

Best Practices

  • Update before you start working to reduce conflicts.
  • Commit often with clear messages.
  • Keep commits focused and small.
  • Use branches for features, releases, or risky changes.
  • Add ignores for generated files and IDE-specific files.
  • Review changes with TortoiseMerge before committing important commits.

Common Troubleshooting

  • No TortoiseSVN menu after install: Reboot Windows; ensure shell extension matches OS architecture.
  • Authentication errors: Check credentials, server URL, and network connectivity; clear stored credentials with Settings → Saved Data.
  • EOL/encoding issues: Configure svn:eol-style and file encodings to avoid platform line-ending problems.
  • Locking issues: For binary files, consider svn:needs-lock property to prevent simultaneous edits.

Quick Reference: Common Commands via Menu

  • Checkout — create working copy from repo
  • Update — sync working copy to latest revision
  • Commit — push local changes to repository
  • Branch/Tag — create branch or tag (copy on server)
  • Merge — apply changes from one branch to another
  • Revert — discard local modifications
  • Resolve — mark conflict resolved after manual fix

When to Use SVN/TortoiseSVN vs Distributed VCS

SVN (and TortoiseSVN) suits projects that prefer a centralized model: a single authoritative repository, simpler history, and centralized access control. Distributed VCS (like Git) excels when offline commits, cheap branching, and distributed workflows are needed. Teams familiar with Windows GUI tools and centralized processes often find TortoiseSVN easier to adopt.

Final Notes

TortoiseSVN makes Subversion approachable by embedding version control into the familiar File Explorer. With practice—updating regularly, committing clearly, and using branches thoughtfully—you can use TortoiseSVN to manage project history reliably and collaboratively.

Key fact: Use TortoiseSVN’s Explorer integration for everyday SVN tasks: Checkout, Update, Commit, Branch/Tag, and Merge.
