Subject: Re: [Tracker] Tracker closing the databse
To: Martyn Russell <mar...@lanedo.com>
The TrackerSparqlConnection is left open since is a class member and is
closed in destructor.
TrackerSparqlCursor is unrefed.
Here i am about to execute a banch of queries.....but i am not interested
in results....i am only interested if query has any results
bool TestClass::ExecuteBatchQuery(std::vector<std::string>
&queries,std::vector<bool>* queryResponseCount){
TrackerSparqlConnection *trackerConnection = getTrackerConnection(); //
here we get the connection and we assign it to a class member...further
calls to this will return the class member
if (trackerConnection == NULL) {
return false;
}
for (int i=0;i<queries.size();++i){
GError* error = NULL;
TrackerSparqlCursor* cursor =
tracker_sparql_connection_query(trackerConnection, queries.at(i).c_str(),
NULL, &error);
if (error) {
queryResponseCount->push_back(false);
g_error_free (error);
continue;
}
if (cursor == NULL) {
queryResponseCount->push_back(false);
continue;
} else {
int cursorcount=0;
while (tracker_sparql_cursor_next(cursor, NULL, &error)) {
if (error)
break;
cursorcount++;
break;
}
if(cursorcount)
queryResponseCount->push_back(true);
else
queryResponseCount->push_back(false);
g_object_unref(cursor);
}
}
return true;
}
