Hi guys,
I stumbled across a problem with worktrees recently; I incorrectly opened a ticket a GitHub for that and it was suggested that it might be fixed in 2.7.1 so I held off reporting it here but as it turned out it is still broken in 2.7.1 so here we go.
The problem is that the paths of the worktrees in $GIT_DIR/worktrees/worktree_name/gitdir are rewritten to read .git instead of /path/to/worktree/root/.git after a git reset --hard (and potentially other operations) which causes all worktrees in git worktree list to point to the current worktree instead of the main repository path.
Let me demonstrate:
# git worktree list
/Users/user/Desktop/Source/Product 2991e32 [master]
/Users/user/Desktop/Source/Product-2.1 3fc1082 [releases/master-2.1]
/Users/user/Desktop/Source/Product-2.2 3ccc3fe [releases/master-2.2]
/Users/user/Desktop/Source/Product-2.3 4044881 [releases/master-2.3]
# cd /Users/user/Desktop/Source/Product-2.1
# git reset --hard
# cd /Users/user/Desktop/Source/Product-2.2
# git reset --hard
# cd /Users/user/Desktop/Source/Product
# git worktree list
/Users/user/Desktop/Source/Product 2991e32 [master]
/Users/user/Desktop/Source/Product 3fc1082 [releases/master-2.1]
/Users/user/Desktop/Source/Product 3ccc3fe [releases/master-2.2]
/Users/user/Desktop/Source/Product-2.3 4044881 [releases/master-2.3]
Servus,
Daniel
