Hi, I'm looking at adding a "git subtree status" command that will tell if a subtree is up-to-date, ahead of, behind, divergant with or unrelated to a remote repo.
I just wanted to check that I'm working this out correctly before writing the code. 1) perform a synthetic subtree split mine=$(git subtree split --prefix=subtree/path) This outputs the SHA1 for this subtree in isolation to the superproject. 2) fetch latest branch HEAD from remote repository we're comparing with git fetch $repo $branch theirs=$(git rev-parse FETCH_HEAD) 3) Find common ancestor base=$(git merge-base $mine $theirs) Where: * $base == $mine && $base == $theirs : up-to-date * $base == $mine && $base != $theirs : behind remote - can pull * $base != $mine && $base == $theirs : ahead of remote - can push * $base != $mine && $base != $theirs : divergent * $base == null : no common ancestor - wrong repo?
