The test app I wrote that downloads big file: https://code.launchpad.net/~lorn-potter/+git/test-servicenetwork Of course, this runs from commandline so is uncontained.
Steps to reproduce: Landing for testing: https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-060 * open system settings->update * when there is a larger update available, start the download. * turn off wifi or walk from wifi zone Known issues: 1. Euronews, Engadget and Today scope to not ever see network 2. Occasionally update check will hang when changing network device(wifi -> 3g) 3. Occasionally update download will not resume properly when network change. I am fairly certain that #1 can only be fixed by moving QtBearer plugin to connectivity-api, although I do not see any apparmor denials in the log, with this change it makes QNetworkRequest require a QNetworkSession, which in turn I believe fails as the known and unfixable QtNetwork network-manager backend issues with apparmor. I am assuming that scopes run in contained space, because other commandline based tests with QtNetworking access work, but Click apps that use QtNetworking fail similarly. #2 and #3 most likely will continue to occur as I believe they are timing issues with the actual network process and the linux networking subsystem does not migrate the actual data/sockets and behave like the Symbian networking backend (which this feature was originally written for) to have seamless network transitions/migration. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1558840 Title: Update downloads hang when connection changes To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1558840/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
