I want to somehow tag the codebase when I push it to production, so that next time when I want to push to production I can do a diff and see exactly what files changed since the last time.
How can I do this with GIT?
Also, how can I list all production builds?
1/ Remember than "pushing to production" is not always the ideal way to put your code in a production environement.
2/ You would have to use a Git hook on the "server" side (i.e. here the Git on the production side, like the the post-receive one to put a annotated tag on what you just received.
Those tags can be then fetch by the first repo, and used to git diff two of those tags.
