"modified content
" means dompdf-module
is the root folder of a git submodule, which is like a kind of nested git repo with modifications of its own. A diff should show it "dirty". You could ignore that state if you wanted to.
You should:
- go in that folder and
git add -A .; git commit -m "modif in dompdf-module"
- go back in the parent repo, and add and commit the new
dompdf-module
gitlink (special entry in the index which records the new SHA1 for that submodule)
Note: after discussion, it appears that:
git diff .
returns Unable to create health/.git/index.lock
, which means the git process has somehow crashed.
Since that git is an old 1.9.5, I asked to upgrade to 2.5.2, in which case, there is no more "modified content" message, and everything seem clea.
Side note: the submodule has been cloned from an url not owned by the user. If any modification need to be done in it, the OP would need to fork that repo, and change the url of the submodule.
Another approach is to delete the submodule, but keep it on the disk, then making it part of the main repo: no more nested .git
folder.
