How to change the SVN URL to commit to?

3 min read 08-10-2024

Subversion (SVN) is a popular version control system that allows developers to manage changes to source code over time. Sometimes, projects may move to a different repository, or you might want to commit your changes to a different URL for various reasons. This article will explain how to change the SVN URL to commit to and ensure a smooth transition without losing your changes.

Understanding the Problem

When working with SVN, you may find yourself in a situation where the original repository URL changes, or you need to switch to a different project or branch within your version control system. In such cases, it's essential to update your local working copy of the repository so you can continue committing your changes without disruption.

The Scenario

Imagine you have been working on a project located at http://example.com/svn/myproject. However, due to organizational changes, the project has moved to a new repository URL: http://example.com/svn/myproject_new. To continue working without losing your local changes, you need to update your local SVN settings to reflect the new URL.

Original SVN Commands

Here’s how you would typically commit changes using SVN:

svn add myfile.txt
svn commit -m "Added myfile.txt"

However, if the URL changes, you'll encounter issues if you try to commit using the old repository path.

Changing the SVN URL

To change the SVN URL in your local working copy, you can use the svn switch command. This command not only updates the repository URL but also keeps all your local changes intact.

Step-by-Step Instructions

Navigate to Your Working Copy: Open your terminal or command prompt and change to the directory of your local working copy:
```
cd /path/to/your/working/copy
```
Change the Repository URL: Use the svn switch command to update the repository URL. The syntax is as follows:
```
svn switch --relocate OLD_URL NEW_URL
```
For our scenario, the command would be:
```
svn switch --relocate http://example.com/svn/myproject http://example.com/svn/myproject_new
```
Verify the Change: To confirm that the URL has been updated, you can check the SVN info:
```
svn info
```
This command will display the current URL of your working copy, and you should see that it reflects the new repository URL.
Continue Working: Now you can continue to add, commit, and manage your files using the new repository URL as if nothing had changed:
```
svn add myfile.txt
svn commit -m "Added myfile.txt to new repository"
```

Additional Insights

Why Use svn switch --relocate: This command is specifically designed to handle situations where you need to change the repository URL while preserving your local modifications. Other commands, such as svn switch without the --relocate flag, might not work properly if the folder structure is different between the two repositories.
Common Errors: If you encounter an error during the switch process, double-check the old and new URLs for typos. Additionally, ensure that your working copy is clean (no pending changes) before performing the operation for best results.

Conclusion

Changing the SVN URL to commit to is a straightforward process that can be accomplished with the svn switch --relocate command. By following the steps outlined above, you can smoothly transition to a new repository without losing your local changes.
