Background

You can view the version history of a file graphically with the command:

ct lsvtree -gra <filename>

Or textually with:

ct lshist <filename>

In addition, the current configspec file can be viewed with:

ct edcs

Problem

I am trying to view previous versions of my view's configspec. However, using either command above, replacing <filename> with edcs does not work. The page on config_spec doesn't talk about anything related to the history of configspec.

Question

How can I view the previous version of a view's configspec?

Since it is not natively supported, you need to set it up somehow:

• take a dynamic view with a repo dedicated to config spec
• write your config spec for a new view and store that as a file within said dedicated view
• use the config spec with cleartool setcs -tag viewTag /path/to/config/spec/file

That way, ant time you want to make changes to your current config spec, write those changes first in that file, and re-setcs to your view.

Then and only then would you get historization of your config spec.
