squash `gh-pages` branch

[jyn514]

Currently, rust-by-example takes up over 146 MB just for the git history. It would be nice to reduce this so contributors to rust-lang/rust don't have to download as much data (rust-lang/rust#76653 (comment)).

You can squash the branch with (https://stackoverflow.com/questions/1657017/how-to-squash-all-git-commits-into-one/1661283#1661283)

git checkout gh-pages
git update-ref -d refs/heads/gh-pages
git commit -m "Redirect to doc.rust-lang.org"

then squash the history with git gc --aggressive. I verified locally that this reduces the size of .git to 84 MB. I'm not sure how to get github to run gc, I think you may have to wait for them to do it automatically (https://stackoverflow.com/a/9138899/7669110).

@marioidival I saw you added a +1 - does that mean you squashed the branch? Can I make it easier somehow?

bump - who should I talk to about this?

Actually it looks like the gh-pages branch has been unused for a while, the last pages deploy was in 2018: https://github.com/rust-lang/rust-by-example/deployments/activity_log?environment=github-pages. I think just deleting the branch altogether should be fine.

Pushed, I believe, the squashed version of gh-pages. Seems to have cut the size down to ~4.7MB on a fresh clone.

Thank you!

That worked like a charm, thank you so much!
