When working withGuidewire Cloud Platform (GWCP), developers use Git for version control. Understanding the internal mechanics of Git is essential for managing InsuranceSuite configuration changes. A common misconception is that Git stores "diffs" or just the changes made to files. However, according to theDeveloping with Guidewire Cloudtraining, acommitis fundamentally asnapshot of the entire project at a specific point in time.
When you perform a commit, Git takes a "picture" of what all your files look like at that moment. To stay efficient, if a file has not changed, Git doesn't store the file again; instead, it stores a link to the previous identical version it has already stored. This snapshot includes metadata such as the author, the timestamp, and a reference to the "parent" commit that came before it. This allows Git to reconstruct the entire state of the configuration at any point in history.
Option C is incorrect because it describes a pointer to changes (a delta), which is how older version control systems like SVN worked. Option B is more descriptive of a "Branch," which is a moving pointer to a commit. Option D describes the "History" or "Log" view. By treating every commit as a complete snapshot, Git ensures that the integrity of the Guidewire metadata is maintained, even when merging complex changes across different developer streams.
