Here's a first attempt at a patch, which unfortunately doesn't seem to work...
The general idea is when an AccessPointRemoved signal is received, we need to ensure that the associated DBus watch is removed. According to the QDbus documentation, DBusConnection::disconnect() should do this. I unfortunately didn't add any debug logging, so will have to take another stab on Monday ( unless someone else can take a look ). ** Patch added: "Initial attempt to patch QNetworkSession to fix match rules leak" https://bugs.launchpad.net/ubuntu-rtm/+source/sync-monitor/+bug/1480877/+attachment/4518542/+files/net-bearer-nm-disconnect-ap-signals.patch -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1480877 Title: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices Status in Canonical System Image: Confirmed Status in Unity 8: New Status in indicator-network package in Ubuntu: Incomplete Status in network-manager package in Ubuntu: Incomplete Status in qtbase-opensource-src package in Ubuntu: Confirmed Status in buteo-syncfw package in Ubuntu RTM: New Status in location-service package in Ubuntu RTM: Triaged Status in maliit-framework package in Ubuntu RTM: New Status in network-manager package in Ubuntu RTM: Incomplete Status in sync-monitor package in Ubuntu RTM: New Bug description: Krillin, rc-proposed, r83 DESCRIPTION: I've been trying to track down the cause of the occasional UI freezes on my Krillin device, and I noticed that whenever the UI freezes for 2-4 seconds, I get a burst of "PropertiesChanged" signals in dbus-monitor Here's a log of what's shown in dbus-monitor: http://pastebin.ubuntu.com/11992322/ I'd guess the problem is in the code that actually catches the signals and acts accordingly. HOW TO REPRODUCE: 1) Move to a place where many wifi hotspots are available 2) Connect the device via USB and run "phablet-shell" and then "dbus-monitor" 3) Use the device while keeping an eye on dbus-monitor output To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1480877/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
