Nobody should be working on master directly. What a strange thing to say. When will 'master' ever be updated then and how? If you mean 'master' as the integration branch for everybody to meet and make progress, it would be more common for everybody to be working on his own topic branch until perfection of the topic, concluded by merging the completed topic to master and pushing the master out to update it, no? >> * pull = fetch + merge!

It could be "git fetch --help" is failing for you, but I am reasonably sure most if not all of the above are answered there; another thing something you may not have known :-). >> Taking all of this together, I think you should stop using two-arg >> pull[*] or fetch, and replace your error-prone recipe with simply >> >> git fetch >> git reset --hard origin/master >> >> Assuming, as before, that your local work is worthless. Is it? >> Otherwise it would be better to run something like >> >> git fetch >> git rebase origin/master Yeah, the latter makes sense, and I think it is a safer superset of the former. If there is nothing of value on 'master', the rebase might stop and give control back to the user, but the user can tell it to skip the cruft that came from the old 'master'. >> [*] it's ok if you use it with an URL instead of a remote nickname > > Why would that be okay? What is the difference? Isn't the nickname > just an alias for a URL? As long as you tell what refspecs to use on the command line, the remote nickname behaves as "just an alias for a URL", so yes, because Thomas is discussing "two-arg pull or fetch", one arg being either nickname or URL and the other is an explicit refspec on the command line, it would be okay because there is no difference in that case. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
