Becasuse of GitHub I am not that used to thinking of git as a peer to peer decentralised version control system - despite the fact I know this theoretically. An upshot of this property that any folder that you have access to can act as a remote.

This came in handy today, rigging up a way to deploy code to a server that has very limited connectivity to the outside world.

First I copied my local copy over to the server.

Then on my workstation I added the folder as a remote:

git remote add prod \\analytics\blah\project_name

Then I can fetch that remote to get the branch metadata:

git fetch prod

after which I can push to it

git push prod

Well sort of. Initally I got this error:

git push prod

Git refused to accept my commits. The issue it is warning me about is that if I did push commits onto the main branch, the HEAD pointer in the copy on the server is not updated. So it would need to be updated by running git reset in the server’s copy.

This can be fixed by running this command on my local machine:

 git config --global receive.denyCurrentBranch "updateInstead"

So now when I try to push commits onto the current branch in the server’s copy it will automatically update the HEAD, provided there is no other uncommited changes hanging out in the working tree. RAD.
