Current behavior 😯

When creating a repo.remote_at("/home/user/repo") with a refspec set to +HEAD:refs/test/repo, the symbolic reference HEAD in the remote repository is not resolved. Instead, the name HEAD is resolved in the local repository, which results in refs/test/repo targeting the local HEAD.

Expected behavior 🤔

The HEAD ref (or any symbolic ref) should be resolved in the remote repository.

Git behavior

Git resolves the HEAD ref in the remote repository.

Steps to reproduce 🕹

In a scratch space...

cd /tmp

...clone a fork of this repository I've made, and run the demonstration test.

git clone --depth 1 https://github.com/jdc-pub/gitoxide.git --branch main gitoxide-demo
cd gitoxide-demo 
git checkout 8ba39778dcc9ca4b95d98e4e1a2a972e68214e1e 
cargo test -p gix --features blocking-network-client --test demo-local-transport-symref-failure

You should see the following output. (I've marked the problem-test as should panic, but it of course should not panic!)
