Subject: Branch switching with submodules where the submodule replaces a folder aborts unexpectedly
Date: Mon, 9 Oct 2017 23:29:01 +0200 (CEST)
Message-ID: <788230417.115707.1507584541605@ox.hosteurope.de> (raw)

Hi,

I'm currently in the progress of pulling some subprojects in a git repository of mine into their own repositories and adding these subprojects back as submodules.

While doing this I enountered a potential bug as checkout complains on branch switching that a file already exists.

I've reproduced it on debian stretch with the following git versions:

master:
git version 2.15.0.rc0.39.g2f0e14e649
pu:
git version 2.15.0.rc0.245.g6d586db062

A script to trigger it is

mkdir -p test/subproject
cd test
git init
touch subproject/1
git add subproject
git commit -m "blah"
cd ..
mkdir subproject
cd subproject
git init
touch 1
git add 1
git commit -m "blubb"
cd ../test
git branch old
git rm -rf subproject
git commit -m "remove blah"
git submodule add ../subproject
git add -A
git commit -m "added subproject"
git branch new
git checkout old

and this fails with 

$LANG=C ./run.sh 
Initialized empty Git repository in /home/XXX/devel/test/.git/
[master (root-commit) 33e6607] blah
 1 file changed, 0 insertions(+), 0 deletions(-)

rm 'subproject/1'
[master 9cbfd57] remove blah

 delete mode 100644 subproject/1

done.
[master 1c67e23] added subproject
 2 files changed, 4 insertions(+)
 create mode 100644 .gitmodules
 create mode 160000 subproject
error: The following untracked working tree files would be overwritten by checkout:
        subproject/1
Please move or remove them before you switch branches.
Aborting

If I'm misusing git here I'm glad for any advice.

Thanks,
Thomas
