Git-subrepo: How to work out if you have changes to any subrepo that haven't been pushed back?

[keithn]

if you have a lot of subrepos, how do you find the ones that got changed as part of your main project and need to be integrated back to their respective repos?

Hi @keithn,
There is unfortunately no easy way to determine this right now. You can look at #274 for an explanation of some steps that can be performed.

There is an -A option for push but then you will push all your subrepos and that might not be the desired behavior.

Try something like this Bash command:

for subrepo in $(git subrepo status --quiet); do echo "New local commits for subrepo $subrepo:"; git subrepo branch --fetch --force --quiet $subrepo; commit=$(git subrepo status $subrepo | grep Worktree: | awk '{print $3}'); (set -x; git log --oneline FETCH_HEAD..$commit); done

@grimmySwe we could add something to status to tell how commits ahead or behind a subrepo branch is.

[grimmySwe]

@ingydotnet But don't you need to fetch and actually perform the subrepo branch to be able to find out the actual status?

[ingydotnet]

@grimmySwe Yes. But I did that. See: https://gist.github.com/anonymous/b772c6806a58a6a54f011cf8a2df427d#file-x-bash-L4

The status command shows a line like thist (if there is a branch):

Worktree: /Users/ingy/src/git-subrepo/.git/tmp/subrepo/ext/test-more-bash  24a6cce [subrepo/ext/test-more-bash]

If we show that line, we can at least say how many commits ahead or behind it it.
