Git submodules are being -dirty?

Question

I just cloned a repository as a submodule into one of my projects. Al is well and working, but all of a sudden i get this message when I do git status;

# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#   (commit or discard the untracked or modified content in submodules)
#
#       modified:   wp-content/plugins/advanced-custom-fields (untracked content
)
#

And if I do git diff I get the following:

-Subproject commit 486e51db9b6ce49114c897ed1893a208d2289a29
+Subproject commit 486e51db9b6ce49114c897ed1893a208d2289a29-dirty

What is worrying is the -dirty change. What does it mean? How do I fix it? I havent made any changes to the repository. But Dreamweaver may have added stupid _notes folders to it. I have tried to delete them but still have same problem. Is this what is causing it to be dirty?

If I try and do a git add -A it still says I have untracked content.

Any ideas?

Answer 1

the -dirty suffix means the submodule has changed. do this:

cd wp-content/plugins/advanced-custom-fields

then

git status

and you'll see what changes are causing your submodule to be dirty.
