Hello,

I have a bare repository clone that I create worktrees off. This works fine, including 'git rev-parse --show-toplevel'.

I enabled per-worktree configs using 'git config --local extensions.worktreeconfig=true', and now I can't get the toplevel anymore:

> git rev-parse --show-toplevel

fatal: this operation must be run in a work tree

Disabling per-worktree configs makes it work again. This also works fine on a non-bare repository clone.

IOW, this works: git clone <url> non-bare (cd non-bare && git worktree add -b master2 ../wtree1 master) (cd wtree1 && git rev-parse --show-toplevel)

This does not: git clone -c extensions.worktreeConfig=true <url> bare.git (cd bare.git && git worktree add -b master2 ../wtree2 master) (cd wtree2 && git rev-parse --show-toplevel)

Is this a bug, or am I missing something?

Thanks,

Clément

Sorry, I mixed up my examples.

This works: git clone -c extensions.worktreeConfig=true <url> non-bare (cd non-bare && git worktree add -b master2 ../wtree1 master) (cd wtree1 && git rev-parse --show-toplevel)

This does not: git clone -c extensions.worktreeConfig=true --mirror <url> bare.git (cd bare.git && git worktree add -b master2 ../wtree2 master) (cd wtree2 && git rev-parse --show-toplevel)

OK, I figured it out by looking at environment.c. The issue is that the base mirror is bare, but the worktree isn't. This makes it work: (cd wtree2 && git config --worktree core.bare true)

This is confusing - should this be set automatically, or referenced more clearly in the 'Configuration File' section of the git-worktree doc?

Thanks,

Clément
