Hi everyone, I've been reading up on the current state of git submodules (our customer's customers want to use them, causing a slight groan from our customer). The usability thing I wonder about - with git submodule update, is it necessary to detach the head to the current (or upstream) head, instead of resetting the current branch to that state? Primary interest in the question: Seeing 'detached head' scares almost everybody. To brainstorm: - as we can already use 'submodule update --remote' to update to the remote head of a branch, it would be logical to have that branch checked out locally (and unfortunately, potentially have that branch's name conflict with the remote branch setup). - when developers more or less accidentally commit on the detached head, all is not lost yet (I remember this being differently), but if the next 'submodule update' just resets again, the commit just made is still dropped, just as in the detached head state. - So, we'd need to have 'submodule update' act closer to the pull or rebase counterparts and refuse to just lose commits (or uncommitted changes). Having a checked-out branch in the submodule would have the advantage that I can 'just' push local commits. At the moment, doing that requires a relatively intricate dance, not at all similar to working in the base (parent) module. I'm working on hooks that automatically update the submodules after a commit change (merge, pull, checkout) in the parent module, but with the additional feature of (a) keeping a branch checked out and (b) avoid discarding local changes. Probably means I shouldn't invoke 'submodule update' at all, and deal with everyting myself. Any thoughs/comments/helpful hints? (Addional complexity: egit/jgit is in use as well, and the work model we will arrive at probabaly needs to work with the current egit.) - Andreas -- "Totally trivial. Famous last words."
