A chain of snapshots
Mira raises the bracket price. To keep it, Git seals the whole page in a commit, chained to the commits before it.
This chapter: What is a commit, and why can’t its past change quietly?
About this chapter
You will learn
- A commit is a snapshot, its parent, who, when and why
- Each commit holds its parent’s name
- Why changing old history renames everything after it
Words you’ll meet
- Commit
- A saved snapshot of the project, with its parent, author, time and message, named by its hash.
- Snapshot
- The whole project as it was at one moment, not a list of changes.
- Parent
