GitLab - Strange Icon and Entry after corrupt commit

Question

I tried to find a description for the following gitlab entry in my repo (in files-view):

Answer 1

It is a git submodule, and you can type:

git ls-tree HEAD -- ws-dom-full

You will see a gitlink, that is a special entry in the index which records the sha1 of the submodule repo. (Mode 160000)

When you clone the parent repo, that folder is empty.
You need:

git submodule update --init

And you will see the submodule content then.

To remove a submodule (from the index and the disk):

git submodule deinit -- ws-dom-full
git rm -- ws-dom-full
git add -u .
git commit -m "Remove ws-dom-full submodule"
git push
