QtSparql request works only when application started from QtCreator

[moldovan_catalin]

Hi,

I have a code that issues this QtSparql request (

"SELECT nie:url(?urn) AS ?url tracker:id(?urn) AS ?trackerid " \
    "WHERE { ?urn rdf:type nfo:Image ; tracker:available \"true\"^^xsd:boolean . " \
    "OPTIONAL { ?urn nie:contentCreated ?created } . } ORDER BY DESC (?created)"

)
and it works fine if I start the application from QtCreator (either debug or just run), but when I run it from terminal I get this error:

QTrackerDirectSelectResult: QSparqlError(9, "GDBus.Error: org.freedesktop.Dbus.Error.AccessDenied: Rejected send message, 2 matched rules; type="method_call", sender=":1.574" (uid=29999 pid=10265 comm="./cuteBoxQml ") interface="org.freedesktop.Tracker1.Steroids" member="Query" error name="(unset)" requested_reply=0 destination="org.freedesktop.Tracker1 (uid=29999 pid=1314 com="/usr/lib/tracker/tracker-store "))", 4) "SELECT nie:url(?urn) AS ?url tracker:id(?urn) AS ? trackerid WHERE { ?urn rdf:type nfo:Image ; tracker:available "true"^^xsd:boolean . OPTIONAL { ?urn nie:contentCreated ?created } . } ORDER BY DESC (?created)"

Does anyone know what this problem might be. From the error code I could figure out that the request was denied. Do MeeGo applications need to have some certificates and capabilities set like Symbian ones or am I missing something?

Yes. You need to use aegis credentials for access. In developer mode you can use aegis-su tool to enable security mode with tokens required for using tracker queries

Please check this link -

https://projects.maemo.org/trac/meeg...rovided-tokens

Check the credentials, tokens for Data management in that.
TrackerReadAccess - Allows to use Query

Hope this helps!

Thanks kusumk,

I cannot access that link, it requires credentials (from maemo.org only managed to create account for garage projects), but based on the information you provided I ran a search on the net and found the info I needed.
Thanks again

Hi
for the record, here is the public version of that link; http://www.developer.nokia.com/Commu...ecurity_Tokens

I've managed to make the application run from the terminal, I don't get the QSparqlError(9, "GDBus.Error: org.freedesktop.Dbus.Error.AccessDenied: Rejected send message, 2 matched rules...
error, but I can't still run the application by tapping the icon in the application launcher (I've triple checked the packaging files and they seem ok). Is there a way to see application launcher logs maybe I can get some hints why it doesn't start?

Can I see your Aegis manifest file?
you app doesn't need aegis file if you run it from SSH or you launch it from QtCreator.

Finally I've managed to get it working, in fact someone on Twitter gave me a hint to change the launch params in the .desktop file from "--type=d" to "--type=e". I don't know what's the difference between them, but it works now.

Here is what "e" and "d" stand for:

Usage: invoker [options] [--type=TYPE] [file] [args]

Launch m, qt, or qdeclarative application compiled as a shared library (-shared) or
a position independent executable (-pie) through applauncherd.

TYPE chooses the type of booster used. Qt-booster may be used to
launch anything. Possible values for TYPE:
m Launch a MeeGo Touch application.
q (or qt) Launch a Qt application.
d Launch a Qt Declarative (QML) application.
e Launch any application, even if it's not a library.
Can be used if only splash screen is wanted.
