std::vector<client_t> Locker::get_late_revoking_clients(double timeout) const
{
std::vector<client_t> result;
if (any_late_revoking_caps(revoking_caps, timeout)) {
// Slow path: execute in O(N_clients)
for (auto &p : revoking_caps_by_client) {
if (any_late_revoking_caps(p.second, timeout)) {
result.push_back(p.first);
}
}
} else {
// Fast path: no misbehaving clients, execute in O(1)
}
return result;
}
client is put to to_evict vector twice in the situation client does't response two caps revoke.
