Not a valid object name when push dot named subrepo

[xiaoyao9184]

I used a directory name with a dot '.', which usually can't be used in a branch name, I tried using git subrepo init and it worked, but when I did a git subrepo push it failed, guessing because of the dot name , the same git repo branch also fails.

git-subrepo: Command failed: 'git branch subrepo/%2eseed '.
fatal: Not a valid object name: ''.

I have the same issue using git subrepo pull. When I execute the git branch command directly - it works just fine

it looks like it should be resolved by PR https://github.com/ingydotnet/git-subrepo/pull/498

After re-init and clone, I found that it was actually because the rebase changed the commit id and the .gitrepo file not same.

Work around? I rebased the master branch and I can push one subrepo, but 3 other nested subrepo's under that one all fail with this error. All subrepos are in rebase mode.

Workaround

1. commit all changes
2. create a branch: git checkout -b subrepo-fix
3. delete subrepo: rm -rf subrepo/
4. re-clone: git subrepo clone git@gitlab.com:org/subrepo.git subrepo/
5. Check for differences in repo state: git diff main (optimally, only subrepo/.gitrepo is different)

If you had changes in the parent repo that are not reset to subrepo state

Reset the files to the state on the main branch: git checkout main -- subrepo/file.txt (be sure not to reset .gitrepo)
