Subject: Re: [git-users] Submodule tracking remote master shows modified
on super project git status after submodule update --remote
The super project 'git status' will tell you if any of it's parts have
been changed, and that includes, the status of the sub-directories
that are sub-modules - and you just said that it had been updated.
Yes they were updated, but their HEAD still is equal to what .gitmodule
"branch" is set to. I would expect it didn't show any modifications
then, unless submodule header != .gitmodule "branch".
Importantly, sub-modules are "never" on a branch, they are (normally)
checked out at a specific commit (remember the bit about fixed
libraries), so that may be part of your problems - It takes a bit to
get though all the manual pages and even then, understanding doesn't
always convert to a useful working practice.... [aside: I still
battle the msysgit/git sub-module structure]
So it makes "branch" setting introduced in Git 1.8.2 just a hint for git
submodule update --remote, and nothing more (unfortunately), right?
Then well this isn't really useful if I need to manually update
submodule tracked SHA1 anyway whenever branch gets updated :(

Hi Adam,
Looking through the documentation history in the History tab
https://github.com/git/git/commits/master/Documentation/git-submodule.txt I
don't see anything that changes the basic underlying behavior about
having a specific commit checked out, but there are updates with
the --branch option for fetching updates.
The super project git tree needs to know the exact version of every part
of the tree, including the sub-modules, to do a commit, so if your
update of the submodule means you have a newer version, then yes, status
will show that change (of checked out commit sha1 id). The ability to
get updates easier for sub-modules doesn't mean that
verification/validation recording has gone away.
If you truly want those new sub-modules updates in the tree then yes, it
is an uncommitted change.
But, it is easy to accidentally misunderstand and talk past each other
on sub-modules... perhaps a short command history. or an example
sequence that can recreate your concern would help clear any
misunderstanding.
Philip
