The leak is not consistent, it can also happen with but I reproduce it maybe more often with There is definitely no Arc anymore in switchboard when that happens. in switchboard.rs impl Switchboard {
pub fn print_state(&self) {
let mut output = String::new();
// Print sessions
output.push_str("Sessions:\n");
for session in &self.sessions {
output.push_str(&format!(" Session {:p}\n", Arc::as_ptr(session)));
}
// Print publishers_by_room
output.push_str("Publishers by Room:\n");
for (room_id, sessions) in &self.publishers_by_room {
output.push_str(&format!(" Room {}:\n", room_id));
for session in sessions {
output.push_str(&format!(" Publisher {:p}\n", Arc::as_ptr(session)));
}
}
// Print publishers_by_user
output.push_str("Publishers by User:\n");
for (user_id, session) in &self.publishers_by_user {
output.push_str(&format!(" User {}: Publisher {:p}\n", user_id, Arc::as_ptr(session)));
}
// Print subscribers_by_user
output.push_str("Subscribers by User:\n");
for (user_id, sessions) in &self.subscribers_by_user {
output.push_str(&format!(" User {}:\n", user_id));
for session in sessions {
output.push_str(&format!(" Subscriber {:p}\n", Arc::as_ptr(session)));
}
}
// Print publisher_to_subscribers
output.push_str("Publisher to Subscribers Mapping:\n");
output.push_str(" Forward Mapping:\n");
for (publisher, subscribers) in &self.publisher_to_subscribers.forward_mapping {
output.push_str(&format!(" Publisher {:p}:\n", Arc::as_ptr(publisher)));
for subscriber in subscribers {
output.push_str(&format!(" Subscriber {:p}\n", Arc::as_ptr(subscriber)));
}
}
output.push_str(" Inverse Mapping:\n");
for (subscriber, publishers) in &self.publisher_to_subscribers.inverse_mapping {
output.push_str(&format!(" Subscriber {:p}:\n", Arc::as_ptr(subscriber)));
for publisher in publishers {
output.push_str(&format!(" Publisher {:p}\n", Arc::as_ptr(publisher)));
}
}
// Print blockers_to_miscreants
output.push_str("Blockers to Miscreants Mapping:\n");
output.push_str(" Forward Mapping:\n");
for (blocker, miscreants) in &self.blockers_to_miscreants.forward_mapping {
output.push_str(&format!(" Blocker {}:\n", blocker));
for miscreant in miscreants {
output.push_str(&format!(" Miscreant {}\n", miscreant));
}
}
output.push_str(" Inverse Mapping:\n");
for (miscreant, blockers) in &self.blockers_to_miscreants.inverse_mapping {
output.push_str(&format!(" Miscreant {}:\n", miscreant));
for blocker in blockers {
output.push_str(&format!(" Blocker {}\n", blocker));
}
}
// Output the state using janus_info!
janus_info!("{}", output);
}and in lib.rs in destroy_session sess.destroyed.store(true, Ordering::Relaxed);
switchboard.print_state(); |
