When there's no query string in the request, _get_query(asgi_scope) returns None, which is unconditionally assigned to attributes["http.query"]. When this None value is later passed through format_attribute() in set_attribute(), it becomes the string "None" via safe_repr(). This causes requests without query strings to have http.query set to the literal string "None" instead of omitting the attribute entirely.

The finally block at lines 369-371 unconditionally sets the span name and source from _get_segment_name_and_source() without checking if a custom name/source was already set by the application (e.g., via set_transaction_name()). This contrasts with the event_processor method (lines 385-400) which has an already_set check that respects custom sources (COMPONENT, ROUTE, CUSTOM). This could cause applications that set custom transaction names to have them overwritten with URL-derived names.
