Understanding file versions and history

In Chapter 4, Changelists, we saw how to submit a modification to a file as a new revision, and how submitted changelists were numbered. In this chapter, we are going to first look at how to get older revisions of files into our workspace and how to understand the history of a file or a set of files. That includes understanding how file revisions relate to changelists, and the state of the repository as of a particular date and time.

We often need to have a look at older versions of files. When looking at a project, you may need to reproduce an older release, or understand a particular baseline which is a set of files or a complete folder or tree.
