* solo groups * cancel-solo * SIP <> AFL/PFL changes The optimized plural-form route_solo_changed() relied on the false premise that solo-groups and port-connections are disjoint sets. -=- e.g. "cancel all solo" calls set_solo(get_routes(), false); Since All routes are affected, the "non_solo_change" set is empty, and no changes were propagated up/downstream. Routes that indirectly change state as group-members, wrongly end up in the "non_solo_change" list instead of the "solo_change" list. If a route feeds another in the same group, no changes were propagated.
