After testing with multithreading there were still problems related to scope and transmitters - because a transmitter that was on the stack as an object could go out of scope before a notify all had finished and lead to invalid data and a crash The solution is to always have Recipients allocated via new() and to use a shared pointer to manage the scope and garbage collect when the last reference goes out of scope. To achieve the threadsafe minimal locking the rules are as follows; * All recipients must be allocated via new() * Register and DeRegister will only happen when on the outermost level of NotifyAll. - all other add or delete will be put into the pending queue and added at the start of the next outer notify all - at outer level notify all a lock will be taken to process pending items * during the main notify processing there will be no locks - however it is also assumed that the recipient list will not be changed |
