Headless app - Release version

• Race of library slow when Alchemy app disabled in the Release version

  Hello

  I'm working on an application that an operation running through a library of Alchemy (written in C and exposed as .as) long.

  Here are the high-level logic to illustrate the idea:

  QNXSystem.system.inactivePowerMode = QNXSystemPowerMode.NORMAL;

  addEventListener (AlchemyLibraryEvent.PROGRESS, onProgress);

  addEventListener (AlchemyLibraryEvent.COMPLETE, onComplete);

  Call the library of Alchemy;

  private void onProgress(event: AlchemyLibraryEvent) {}

  update of the progress made in the user interface;

  }

  private void onComplete(event: AlchemyLibraryEvent) {}

  QNXSystem.system.inactivePowerMode = QNXSystemPowerMode.STANDBY;

  If app is in {disabled state

  QNXSystem.system.powerMode = QNXSystemPowerMode.STANDBY;

  }

  }

  In the bar-descriptor:

  run_when_backgrounded

  What happens is that the app works perfectly well (no matter the app is active, put off the power, the unit standby) in a debug build (by token of debugging).  However, when it is exported as a signed bar and running on the same physical device BB10, it normally only works when the application is active.  Whenever the application is disabled (when the screen is off, or app pushed back and another application is brought to the foreground), the application runs always, but at a very slow speed (about 1/15 of the original speed).

  I did some debugging and confirmed that when the application is disabled, she was continuing with NORMAL power at the rate of 60 frames per second, which seems to be quite normal.  What I don't understand is why the chemistry library runs a lot slower in the background in the Release version.

  As a proof of concept, I added the following code just before inactivePowerMode to NORMAL:

  NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;

  The build version will run at normal speed and the screen turn off.  However, if I press the device power button, or push the app thoroughly (and make another application in the foreground), he repeats the same behavior running slowly.

  Any ideas would be much appreciated!

  No, there is no way to take more CPU power when in the background. The operating system applies this to the user, so they have no apps churning through their battery on them. I would recommend that you inform users of this, so they can decide what they want to do. BlackBerry 10 is expected for the multitasking well, so I expect that they will enjoy and put the application in the background.

• Debugging in the Release version

  Hello world

  my new app uses a card to process the data. The data processor triggers a signal and slot this respons by closing the card. Well, at least while debugging. I tried the release just before you download for the BlackBerry World and I noticed that the card don't be closed. Data are transformed very well, but somehow the signal is not properly raised or the card cannot be closed. I have attached a bit of code to illustrate my operation.

  The processing of the data

  void WebpageFetcher::done()
  {
      DbHelper* dbHelper = DbHelper::getInstance();
      dbHelper->insert(some data);
      //Signal that we're done!
      emit fetchDone("Success!");
      delete dbHelper;
  }
  

  The Application

  fetcher = new WebpageFetcher(uri);
  connect(fetcher, SIGNAL(fetchDone(QString)), this, SLOT(fetchingDone(QString)));
  

  void ApplicationUI::fetchingDone(QString msg)
  {
      // Assemble message
      CardDoneMessage message;
      message.setData(msg);
      message.setDataType("text/plain");
      message.setReason("Success!");
      // Send message
      m_invokeManager->sendCardDone(message);
  }
  

  Now my question is: How can I see the output in Release version? qDebug will obviously not work, but I need a tool to help me understand this issue.

  Looks like the culprit was "build automatically" neglected my amendments to the code for the Release version. Although 4 wasted hours, could be worse

• Best/Recommended way to record information in the Release version

  Hello

  I've searched around, but don't see any results on the issue yet. Then I would ask what is the best/recommended way to record Release version information?

  I use Momentics IDE 10.2. When I choose run or Debug, qDebug() & qWarning display information very well in the console of the IDE, but with "run" they don't show anything in the console. Tested on both Q10 & Simulator.

  Thank you

  Install your own messages QDebug Manager, do write to a file, for example newspapers newspaper. Then open a terminal on the device, navigate to the file and the type of your application:

  # tail -f logs/log
  

  to view the log file.

  Change your main.cpp along these lines:

  #include 
  
  static FILE * logFile;
  
  void logger(QtMsgType type, const char * msg)
  {
      Q_UNUSED(type);
      std::fprintf(logFile, "%s\n", msg);
      std::fflush(logFile);
  }
  
  Q_DECL_EXPORT int main(int argc, char **argv)
  {
      logFile = fopen("logs/log", "a");
      qInstallMsgHandler(logger);
      Application app(argc, argv);
  
      // Create the Application UI object, this is where the main.qml file
      // is loaded and the application scene is set.
      new ApplicationUI(&app);
  
      // Enter the application main event loop.
      return Application::exec();
  }
  

  Note: the file will be closed by the operating system, more messages are seen if you don't shut it down at the bottom of the hand. Why? because c is destorying local variables (app) at the end of the main, and who calls the string whole qt of parent-child destructor for your class of application as well.

• Long-term headless app work: QTcpSocket receive do not

  We have an app without long-term head that uses sockets for IPC.

  Headless part contains a QTcpServer, the user interface of the QTcpSocket.

  the code without a head:

  server = new QTcpServer(this);
  bool ok = connect(server, SIGNAL(newConnection()), this, SLOT(onNewConnection()));server->listen(QHostAddress::LocalHost, m_port);
  

  user interface code:

  bool stateOk = connect(clientSocket, SIGNAL(stateChanged(QAbstractSocket::SocketState)), this, SLOT(onStateChanged(QAbstractSocket::SocketState)));
  if (!clientSocket->isOpen()) {
      clientSocket->connectToHost(QHostAddress::LocalHost, m_port);
      bool conOk = connect(clientSocket, SIGNAL(connected()), this, SLOT(connected()));
      bool disconOk = connect(clientSocket, SIGNAL(disconnected()), this, SLOT(disconnected()));
      bool readReadOk = connect(clientSocket, SIGNAL(readyRead()), this, SLOT(commandReceived()));
      bool errorOk = connect(clientSocket, SIGNAL(error(QAbstractSocket::SocketError)), this, SLOT(error(QAbstractSocket::SocketError)));
      Q_ASSERT(errorOk);
      qDebug() << "connected to server socket";
  }
  

  output debug shows headless headless app is running constantly, the signal is properly connected, the socket for the server returns isListening() to true.

  debug output of the user interface shows that all signals are correctly connected, and onStateChanged goes from HostLookupState to ConnectingState and finally to ConnectedState

  At this point, I'd wait the server socket to pull the signal of newConnection, but alas, it isn't.

  I generate and run the xandos example and it works correctly, but it does not long-term use and has the server in the user interface, while the part without head connects.

  I suspect that the app without head doesn't have an event loopand QTcpServer documentation states:

  Although QTcpServer is mostly designed for use with an event loop,it's possible to use it without one.In that case, you must use waitForNewConnection(),which blocks until either a connection is available or a timeout expires.
  

  Now I wonder:

  The long March without head app has an event loop?

  If this is not the case, how best to use the blocking call without disabling the rest of its features? A thread?

  Write that post little got me on the right track already, a problem merging caused the socket to the server must be started before you call the constructor of the Application (which provides the event loop).

  Now the server is running, receive a few orders, then she stops unexpectedly, the fires of the user interface
  QAbstractSocket::RemoteHostClosedError changes the State of ClosingState and UnconnectedState

• BB10-Release Version

  I noticed a new problem with the Release version:

  my application streams music from a cloud server.  He asked the resource of networking to ensure that play continues in standby mode.  However, the Release version stop playing at the end of the current track.  In debug mode, and on the PB, the titles are downloadable and continues to play.

  Something has changed in BB10, regarding requests for resources?  Or in standby mode?
