My spam filter is fine (they are not in spam...)... probably gmail just failed to send to / receive from vger.kernel.org for the last several hours (or sth similar...)....

I C. So in my real case it is probably because the different server I am pulling from are on different branches.... (for a shallow clone, it may look the same with commits from different projects?...)

So is there a way to ask for a certain commit from a certain server and update local files that has changed accordingly? For the server, it shouldn't be much different from another shallow clone (although it would be better if locally existing objects are not transferred.). But I am wondering what client side command/script do I need to use.
