You failed to quote the part of my email where I talked about how we set an evironment variable to pass a hint to lockfile.c running within the git-update-ref subprocess to instruct it to perform a different style of locking, one that would work as a "recursive" lock. Such a recursive lock could be useful for a whole lot more than just the update hook. But it would at least allow the update hook to use git-update-ref to safely change the ref, without receive-pack losing its own lock on the ref. -- Shawn. - 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
