Adding a worktree from a working copy with submodules doesn't work.
In the config file I have
[submodule]
recurse = true
It that's not present, I don't find the problem.
# Preparation
$ git --version
git version 2.20.1
$ cd /tmp/
$ git init main_repo
Initialized empty Git repository in /tmp/main_repo/.git/
$ git init repo_submod
Initialized empty Git repository in /tmp/repo_submod/.git/
$ cd repo_submod
$ echo Some text > file.txt
$ git add file.txt
$ git ci -m "First commit in subrepo"
[master (root-commit) ebc9325] First commit in subrepo
1 file changed, 1 insertion(+)
create mode 100644 file.txt
$ cd ../main_repo/
$ git submodule add /tmp/repo_submod submod
Cloning into '/tmp/main_repo/submod'...
done.
$ git ci -am "First commit, add submodule"
[master (root-commit) 695b3a1] First commit, add submodule
2 files changed, 4 insertions(+)
create mode 100644 .gitmodules
create mode 160000 submod
# Problem 1 (can't run worktree add)
$ git worktree add ../wt -b new_branch
Preparing worktree (new branch 'new_branch')
fatal: exec '--super-prefix=submod/': cd to 'submod' failed: No such
file or directory
error: Submodule 'submod' could not be updated.
error: Submodule 'submod' cannot checkout new HEAD.
fatal: Could not reset index file to revision 'HEAD'.
The new directory (../wt) is created and removed (seen with strace).
The new branch is created and not removed.
# Problem 2 (submodule status seems not to detect some cases)
$ pwd
/tmp/main_repo
$ git submodule status
ebc9325f7b19164c9bdfd05263481ded66d7bd7d submod (heads/master)
$ rm submod/file.txt submod/.git
$ git submodule status
ebc9325f7b19164c9bdfd05263481ded66d7bd7d submod
So, I have a plain, empty directory where the submodule should be. Not
having any 'first char', I'd expect it to be checked out and up to
date. Is this expected?
Thanks a lot for the work!
