Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Consistency Group: None Status: Open Resolution: None Priority: 6 Private: No Submitted By: Stefan Rossbach (kargor) Assigned to: Nobody/Anonymous (nobody) Summary: Race condition when synchronizing user lists Initial Comment: Host: A Client: B Client: C Client: D D invites E First bug: The host does not know anything as long as D has not synchronized the user lists, but E does ! Second bug: Instead of D, A invites E While synchronizing the user lists, following can happen: A tells E that B,C and D are part of the session. E now may send an activity to B,C and D (e.g its color). B,C and D does not know anything about E yet, discarding the activity and blowing up their ActivitySequencer for E, because when E sends another activity (now B,C and D may know E), the sequencer is still waiting for the former activity which was discarded. The sequencer stalls for E unless a timeout occured AND E sends another activity. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=843359&aid=3544930&group_id=167540 ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
