Scheduler usage

[adamski]

I'd like to make use of the scheduler so that I can check login status on a thread, and set up the realm once logged in on the main thread.

I'm using Scheduler::invoke on a scheduler created with Scheduler::make_default(). Is there something I'm missing?

            auto scheduler = realm::util::Scheduler::make_default();
            std::thread loginThread ([this, username, scheduler]()
                                     {
            try
            {
                std::future_status status;
                // TODO: Improve security with JWT based login
                std::string credentials = "{ \"username\": \"" + username + "\" }";

                std::cout << "Logging in..." << std::endl;
                auto userFuture = app->login (realm::App::credentials::function (credentials));
                std::cout << "Waiting for response" << std::endl;

                do
                {
                    switch (status = userFuture.wait_for (50ms); status)
                    {
                        case std::future_status::deferred:
                            std::cout << "deferred\n";
                            break;
                        case std::future_status::timeout:
                            std::cout << "timeout\n";
                            break;
                        case std::future_status::ready:
                            std::cout << "ready!\n";
                            break;
                    }
                } while (status != std::future_status::ready);

                user = userFuture.get();
                std::cout << "Logged in. User ID is " << user.identifier() << '\n';

                scheduler->invoke ([this]
                                   {
                                       setupSyncedRealm();
                                       setupSubscriptions();
                                       setupObservers();
                                   });
            }
            catch (const realm::app_error& e)
            {
                std::cout << "Error logging in: " << e.message() << std::endl;
                return;
            } });

            loginThread.detach();

@adamski The scheduler is not intended to be used this way, its purpose is to perform change calculations for notifications and notify the callback when they are ready.
