There are many potential sources of risk, and the "safely" refers to protection against a particular kind of risk: updating from a value that you did not intend to (i.e. you examined and decided the update is good, time passes while somebody else might have mucked with the ref, and then you execute the update you decided to do). And the safety afforded to you is with "git update-ref ref newvalue oldvalue" that makes sure the ref still points at the oldvalue and refuses to update it to newvalue if it doesn't. -- 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
