Change setting requires manual refresh

Status changed to 'Confirmed' because the bug affects multiple users.

Added unity8 because it's not entirely clear to me what's at fault here. Could be the scope itself, the scopes runtime, or the dash. I'll have a look at this next week.

I don't see how unity8 can be at fault here, maybe you meant unity-scopes-shell ?

Sorry, that was me being ignorant. Thanks for pointing this out!

It's worth re-checking after latest keyword-based aggregation land (music/video aggregators were refactored a lot for this feature; also they now use BufferedResultForwarder from scopes API instead of custom buffering) in vivd.

same issue (Music scope) with vivid-proposed 184:

phablet@ubuntu-phablet:~$ tail -F .cache/upstart/scope-registry.log
terminate called without an active exception

phablet@ubuntu-phablet:~$ system-image-cli -i
current build number: 184
device name: krillin
channel: ubuntu-touch/vivid-proposed
last update: 2015-04-14 13:43:05

version ubuntu: 20150414
version device: 20150326-f0c5ba5
version custom: 20150414
phablet@ubuntu-phablet:~$

So the interesting part is: "terminate called without an active exception". This usually means a thread was terminated without join(). Looking at a stack trace of the seemingly duplicate bug (Bug #1432725), looks like that just may be the problem:

It's pretty much guaranteed that this is the same issue as the one fixed by this MR (which has merged):

Pawel, could you verify that your recent merge fixes this problem too?

I am seeing the same issue when I add a setting to an agg scope and change it. The setting I add is NOT enable/disable child scope (as those now work and are auto added). The setting is a simple list type

[cardinality]
type = list
defaultValue = 1
displayValues = 5;10;15
displayName = Child scope results

After this ^ happens on setting change & return to scope, the user needs to pull to refresh the scope, and the setting (and all else) works fine.

Kyle, that's almost certainly the same issue as the one here: https://code.launchpad.net/~stolowski/unity-scopes-api/fix-settings-thread

That branch has merged into devel, but not landed in the archives yet because of the Vivid freeze. If you grab devel and install that, I would expect the problem to disappear. Please let me know if it doesn't!

I am not seeing this bug anymore so probably michi's #13 comment is correct.

Closing this because this was fixed by https://code.launchpad.net/~stolowski/unity-scopes-api/fix-settings-thread
