Syncing fork since commit history edit.

[jnellis]

So I noticed my repo was borked from the recent git history mangling, effectively disconnecting it from easily fetching upstream merges. Roughly 1000 forks are currently like this so its a bit of an issue perhaps (I'm no git wizard so maybe its not.) After some searching about I came across these incantations to force your local repo to fetch from this upstream repo then force push to your github fork.

The simplest way to ensure you are not running into issues is to delete the fork + fork again.

[jnellis]

Yep. Didn't want to do that though, thought there might be some other way. There's at least one fork that has been forked itself and if anyone was using Issues on their fork it would be lost I think. Anyway, I didn't see this addressed anywhere and things like this can have roadblocking effect on further participation. Again, not a git wizard, but I'm betting there is still some dark magic that could have been invoked to delete specific large commits without disrupting the flow of things too much.

As @jnellis mentioned the easiest way is to reset the local branch:

If not done already you first have to add the coding-horror repository as a remote:

git remote add upstream https://github.com/coding-horror/basic-computer-games.git

After that you need to checkout master and overwrite it with the remote:

git fetch upstream
git checkout master
git reset --hard upstream/master
