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

 

@Andrea

Thanks for the updates.  Your stopping of the bridge and indicator are
useful clues.

Again, we still have no proof that there's spamming of the bus yet.  Is
there a lot of traffic, yes?  But as pointed out before, the bus is
meant to handle lots of traffic.  I'm not claiming the bug isn't related
to bus traffic, it's just that we haven't managed to pinpoint a smoking
gun yet.

It'll be interesting to see if you get the same set of JobAdded/Removed
messages on your bus when enabling/disabling WiFi after you re-flash.

Title:
  Access points' "PropertiesChanged" dbus signals freeze UI on mobile
  devices

Status in indicator-network package in Ubuntu:
  Incomplete
Status in network-manager package in Ubuntu:
  Incomplete

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
