git - Pushing to github after a shallow clone

Question

I had a massive git repo because of a huge number of commits, so following advice here I created a shallow clone. I've made changes to this new local repo, and now I want to push to my origin at Github (and then on to my staging and production remotes on Heroku). Perhaps one day I'll learn to read the documentation:

The git clone --depth command option says

--depth Create a shallow clone with a history truncated to the specified number of revisions. A shallow repository has a number of limitations (you cannot clone or fetch from it, nor push from nor into it)

So... how can I unpick myself from this situation and push my code to Github?

Answer 1

Git (since 1.8.3) now has an official way to fetch the full history of a shallow clone:

git fetch --unshallow

From the git fetch documentation:

--unshallow

If the source repository is complete, convert a shallow repository to a complete one, removing all the limitations imposed by shallow repositories.

If the source repository is shallow, fetch as much as possible so that the current repository has the same history as the source repository.
