Understanding the "Maximum Function Recursion Depth" Error in Git

If you’re encountering the message: "Maximum function recursion depth (1000) reached" when running a git subtree command like git subtree split -P foo/ -b "foo-branch", you’re not alone. This error can be frustrating, especially when the same command works seamlessly on your coworkers' machines. The problem typically points to a misconfiguration on your local setup rather than the command itself. In this post, we’ll delve into the underlying causes and provide a straightforward solution to get you back on track.

Causes of the Error

The error arises from the shell environment in which Git is executed. Specifically, on Ubuntu 21.04, the default shell dash can be overly restrictive concerning function recursion depth. Here’s why this matters:

Recursion Depth: Every time a function calls itself, it adds to the stack. If this exceeds a certain limit (in this case, 1000), you’ll receive a recursion depth error.

Shell Configuration: Your default shell being dash instead of a more flexible shell like bash plays a crucial role in this problem. The default configuration limits functions, causing Git subtree to fail.

Solution: Reconfiguring the Shell

Step-by-Step Instructions

Open Terminal: Launch your terminal where you can input commands.

Reconfigure Dash:
Run the following command:

Selecting the Default Option:

During the setup wizard that appears, you’ll be prompted with an option to choose between dash and bash.

Select "No" when asked if you want to use dash as the default system shell. This will revert back to bash as the default shell.

Test Your Command Again:
After making the change, attempt to run the git subtree split command again to see if the error has been resolved.

Conclusion

By simply changing your default system shell from dash to bash, you alleviate the restrictions causing the recursion depth issue. This fix should enable you to run Git subtree commands without further complications. If you continue to face issues, ensure your Git installation is up to date or check for any additional configurations in your shell or Git settings.

Embrace the flexibility bash offers, and happy coding!
