Amarok StatSyncing GSoC: week 4

Matěj Laitl · June 17, 2012 · 1 min read

Hi, in case you forgot, I'm working on my GSoC project about statistics synchronization in Amarok. This week, I've made the behaviour (as opposed to the looks) of the synchronization dialog perfect. Do you think I'm being too bold? Check the rest of the post. :-)

I add a couple of buttons each week, I promise I won't continue endlessly. :-)

What I've done this week:
  • Eliminated some false-positives in detection of rating conflicts (uses some heuristics, but will do)
  • Made "Updated Tracks" and "Tracks With Conflicts" combo-box options enabled only if there are actually some such tracks.
  • Made synchronization aware of iPod's recent play count feature - now the synchronized value is correct even if you play the same song in Amarok and on iPod simultaneously.
  • Added status bar so that you know the counts.
  • Qt's tree view combined with filtering can unfortunately forget which nodes are expanded. I've worked it around with some witty code. :-) On first show, tracks with conflicts have their nodes expanded.
  • Added the "Take Ratings From" button.
Problems I've faced:
  • While I'm generally satisfied with the dialog's behaviour, its appearance isn't particularly pleasing. I will for sure fix minor things like displaying rating with stars, but I'm not a usability expert. Fortunately, there seems to be an easy way to get it reviewed now.
  • To support iPods' recent play count, I've added a method to Meta::Track, which now seems rather unfortunate. I need to consult it with other Amarok developers, but probably I'll factor it into a Capability.
What's next:
  • Next week I'll make the synchronization dialog two-step: in step 1 you choose what fields to synchronize and what collections should participate.  What you see above will become the step 2.
  • I'm still a little ahead of my schedule and that's good. This means that I'll have a chance to look into realms sooner. There is some activity on code in Amarok from Harald Sitter recently (great!) and it turns out that rather big re-factoring will be needed.
You can test my work by pulling and building gsoc branch of my Amarok git repository clone, it already works! I also publish weekly diffs with more technical details on KDE's review board which may be a more convenient way to review my code and to comment on it: week 1 week 2 week 3 week 4
