Graal doesn't work with latest version of Git (2.35.1) #112

Closed jjmerchante closed 2 years ago

When Perceval updates the repository to fetch the items, Git refuses to fetch into the currently checked out branch of any working tree. This change was made in the lastest version of Git (2.35.1): https://github.com/git/git/commit/8bc1f39f411e06b940230dc84da5568dfafec922

  File "/home/runner/work/grimoirelab-graal/grimoirelab-graal/src/perceval/perceval/backends/core/git.py", line 278, in __fetch_from_repo

perceval.errors.RepositoryError: git command - fatal: refusing to fetch into branch 'refs/heads/master' checked out at '/tmp/worktrees/graaltest'

It only fails when the worktree is created using the following command:

git worktree add /tmp/worktrees/graaltest master

But it doesn't fail when the worktree is created without providing a branch, because the branch name is by default the name of the worktree:

git worktree add /tmp/worktrees/graaltest
