Debusine Workers only support the default scope

erickv on IRC reported that the debusine worker was failing to execute tasks in a non-default workspace.

An inspection shows that the debusine worker is entirely unaware of scopes. Oops!

In practice, the worker has only been able to act on workspaces in the default scope.

Original Report:

Debusine issue reproducer

Install debusine, create a user, enable workers.

Run on server:

sudo -u debusine-server debusine-admin scope create myscope
sudo -u debusine-server debusine-admin group create myscope/Admins
sudo -u debusine-server debusine-admin workspace create myscope/base Admins
sudo -u debusine-server debusine-admin group members myscope/Admins --add YOUR-USERNAME

Run on client, after changing the token to your user's:

echo "result: true" | debusine --scope myscope create-work-request noop --workspace base

Back on server, verify /var/log/debusine/worker/worker.log:
