[Desktop-packages] [Bug 1480877] Re: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices

In parallel there has been some discussions on bug #1404188 about dropping the usage of network manager backend, even though unlikely in vivid-overlay unless seen as a bullet proof option. If you want to try out how that would look like, install the silo 032 on rc-proposed but _without_ upgrading

I just added tasks for the packages mentioned in comment #65. Some things learned today: - the sub-component of QNetwork that's most likely the cause is called Bearer Management. One of it's classes, QNetworkSession includes a plugin for NetworkManager which creates listeners for new

@taiebot65 I don't think this is related to bug #1462664. This is specifically related to the number of processes watching individual network-manager access point objects, and the fact that these processes leak match rules, so they continue to add match rules to dbus for new access points, but

Here's a script that calls dbus-monitor with the correct match rules in order to catch AccessPointAdded and Removed signals, as well as PropertiesChanged signals for the Device.Wireless 'AccessPoints' property. ** Attachment added: "monitor-aps.sh"

@Pat We might want to hotfix this once we come to fully understand it( and I think we're getting close ). While working with tvoss a fixes to location-services, we realized that by default, the get-all-match.py script only outputs warnings. While reviewing a test run from tvoss, I didn't see

Here my feedback from installing silo 10 as per bug #1462664. I have been walking to town today and did not notice any lag for the time i was in town. Normally i am experiencing some hangs of more than 1 min before i can get a working phone. Today i checked repeatedly my phone and it did wake up

Re: the xenial version of dbus, you need to be careful as although I was able to get it to run on a krillin, it prevented the UI from coming up on mako. This is why I backported the changes and pushed to my PPA ( 1.8.12-1ubuntu5~awe3 ). https://launchpad.net/~awe/+archive/ubuntu/ppa @Andrea

Here's some test results from me. tl;dr stopping location services helps a lot, but still tiny UI stuttering. My routine is to leave my apartment and walk down the street. This means I go from wifi to 3G. What happens on current images is: 1) As my phone notices that I'm out of wifi range, it

@Michael Thanks again for your help with testing this. 1) When the phone disconnects from an AP, the scan interval drops to it's lowest possible interval ( 20s ), as the goal is re-connecting as quick as possible. It'll eventually drift back to ~60s. 2) I also get the very brief <= 1s stutter

So re-testing with krillin ( rc-proposed, #162 ). Confirmed that using a patched version of dbus 1.8, the match rule limits aren't enforced, so each of the loc processes slowly grows its number of match rules till they cap out at 5000 each. So, WiFi enabled & connected, with the HERE app running

Forgot to add the output of the system match rules for mako. Note at the time this was run both slpgwd and posclientd both have 616 match rules. It looks like stopping the location service ( via upstart or the indicator ) may have cleared the rules for ubuntu-location-servicesd. ** Attachment

One of the frustrating parts about this bug is the incomplete description, and the fact that it's been nigh impossible to nail down a set of concrete steps to reproduce... Also, the bug description contends that NM 'PropertiesChanged' signals are causing the UI freezes, however we have no idea
