The update does two things: upload objects to the database, and then update the reference. Adding objects to the database does not change the repository until the objects are reachable from a ref. Updating the ref is usually done giving the expected old sha1, and locks the ref, so it can't change in the meantime. I don't know this part of the code very well, but check refs.c for the C part, and "git update-ref" for the plumbing interface. -- Matthieu Moy http://www-verimag.imag.fr/~moy/ -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
