Re: Git commit hash clash prevention

the other day during a workshop on Git, one of the attendants asked
about the scenario when two developers, Jane and David, both working
on the same project, both create a commit and the two just so happen
to have the same SHA-1. I realise that the likelihood of this
happening is about as high as the chance of <insert witty joke
here>, but it *is* possible, isn't it? Even though this is thus
somewhat academic, I am still very curious about it.

What happens when David now pulls from Jane? How does Git deal with
this?

Cannot happen in practice.

But just in case git trusts object it already has in repository over
object which just got fetched (or pushed).
