Taking a look at some of our new DeleteSeries changes I'm seeing two paths in which we can escape the function without releasing the lock We hold the lock here 40ec5b0/tsdb/store.go#L1652 And then within this code block we can return errors without releasing the lock: 40ec5b0/tsdb/store.go#L1665-L1682 We do not log out the errors on the server side and bubble up by returning the error via the http handler to the client 40ec5b0/services/httpd/handler.go#L1060-L1064 (cherry picked from commit c67028a)
