Hi Pawel (again 😀)
Thanks a lot for your help! I added workaround in my scope (used QSet
to preserve uniqueness of content) and now it works well!
Seems that you should write this somewhere in documentation, because
someone else can get such crash.
My bad - I didn't try to switch-off sources one by one.
Again, huge thanks!

Hi Roman,
I've just found a case which makes dash crash - this is when my
test scope creates at least two duplicated results for given
search request (same uri, title, icon... everything - they need to
be exactly the same to trigger the crash)
Can you check if same thing happens to your scope (may be a
problem with the remote service you're using, not your scope)?
Cheers,
Pawel

Hi all
I deveped scope called "Academy". C++ source code is:
https://github.com/QtRoS/courseexplorer (courseexplorer is
working name)
First time it worked fine on my phone (BQ E4.5, latest stable
update). Now sometimes I am getting dash crash - "Scope"
/application/ restarts (don't sure if I can call it application).
Here is scenario:
1. Open scope "Academy"
2. Find something, for example "Haskell"
3. Push back arrow (or just clear search query)
4. Maybe you will get crash
So it fails with *empty search*. Interesting thing is that you
can run empty search any times via "Pull to refresh" - it
works well. It crashes only after search with non-empty query
(when you are returning back).
Another interesting thing is that I am using
ScopeBase::cache_directory as cache for search results,
downloaded for *empty search* (when search request is
non-empty, I am always using data from coursera, edx and
etc.). So when scope is requested to show all results (query
string is empty) I am pushing about 400 results almost instantly.
I have logging in my scope. Here it is (in files
scope-registry and unity8-dash):
http://paste.ubuntu.com/15072249/ - the most interesting part is:
Query: Finished with source: "Udacity"
That means that all my code in Query is finished.
http://paste.ubuntu.com/15072258/ - the most interesting is:
flushUpdates: "academy.mrqtros_academy" #results = 79
finalize: false
flushUpdates: "academy.mrqtros_academy" #results = 81
finalize: false
flushUpdates: "academy.mrqtros_academy" #results = 92
finalize: false
Loading module:
'libubuntu_application_api_touch_mirclient.so.3.0.0'
file:///usr/share/unity8//Dash/Dash.qml:39: ReferenceError:
window is not defined
file:///usr/share/unity8//Dash/Dash.qml:265: ReferenceError:
scopeStyle is not defined
Seems that dash failed to flush results of search.
Please, help me with that. It's part of scope showdown and I
really don't want to lose scores because of that.
P.S. Scope works fine on desktop (stress-tested it well)
P.S.S. I have strong C++ knowlege, so I am almost sure, that
it is not my fault
P.S.S.S. Yes, I tested old version without cache - also
crashes sometimes.
