What does a roll back of a bundle entail when a commit fails?

When a commit fails, rolling back a bundle involves restoring the bundle to its original state. This process is critical in maintaining the integrity of the data and ensuring that the system does not end up in a corrupted state due to partial or unsuccessful commits.

During the rollback, all changes made in that bundle are undone, allowing the system to revert to the condition it was in before the changes were applied. This is particularly important in development and code management environments, such as those used in Guidewire, where maintaining a stable and reliable codebase is essential for continuous integration and deployment.

The other options do not accurately describe the rollback process. For example, committing all changes regardless would lead to potential inconsistencies, while only undoing the last action does not fully address the errors associated with an unsuccessful commit. Lastly, stating that no change is made contradicts the necessity of the rollback process when there is a commit failure. Thus, restoring the bundle to its original state ensures a clean environment for developers to continue their work safely.
