QUESTION

Server crashing while being interrupted sending large chunk of data

Asked 2022-Apr-05 at 10:50

My server crashes when I gracefully close a client that is connected to it, while the client is receiving a large chunk of data. I am thinking of a possible lifetime bug as with the most bugs in boost ASIO, however I was not able to point out my mistake myself.

Each client establishes 2 connection with the server, one of them is for syncing, the other connection is long-lived one to receive continuous updates. In the "syncing phase" client receives large data to sync with the server state ("state" is basically DB data in JSON format). After syncing, sync connection is closed. Client receives updates to the DB as it happens (these are of course very small data compared to "syncing data") via the other connection.

These are the relevant files:

How to register QObject class in CMake with qt_add_qml_module?

ANSWER

Answered 2022-Feb-21 at 07:35

You just need to add QML_ELEMENT to your QObject-derived Expense class's header and make sure you have moc enabled in your CMakeLists.txt. In application case it doesn't matter if the expense.h/cpp sources are included via qt_add_executable or qt_add_qml_module. I think it's clearer to add them to qt_add_qml_module SOURCES. Then you just import module URI in you QML file. In the example below I'm printing out property value from Expense object in QML.

Correct Answer

The problem is that this is a bit extract. Chisel lets you do foo(bar) to extract the bit at index bar out of foo. The above code, as written, is a bit extract even though the user wants it to be a mistake.

Unfortunately, this is a known gotcha and it's not reasonable to error on this without false positives while still allowing users to use the () syntax for bit extracts.

Incorrect Original Answer

It's valid syntax per Scala rules. What's going on here is that the code is really two statements, but the indentation is confusing. It's equivalent to:

found some answers to my own question, sharing with community

6-sec auto-switch mode is a new feature in Android 12, which works only if (mode == AudioSystem.MODE_IN_COMMUNICATION) (check out flow related to MSG_CHECK_MODE_FOR_UID flag). This should help for MODE_IN_COMMUNICATION set to AudioManager and left after app exit, this was messing with global/system-level audio routing. There is also a brand new AudioManager.OnModeChangedListener called when mode is (auto-)changing

and setSpeakerphoneOn turns out to be deprecated, even if this isn't marked in doc... we have new method setCommunicationDevice(AudioDeviceInfo) and in its description we have info about startBluetoothSco(), stopBluetoothSco() and setSpeakerphoneOn(boolean) deprecation. I'm using all three methods and now on Android 12 I'm iterating through getAvailableCommunicationDevices(), comparing type of every item and if desired type found I'm calling setCommunicationDevice(targetAudioDeviceInfo). I'm NOT switching audio mode at all now, staying on MODE_NORMAL. All my streams are AudioManager.STREAM_VOICE_CALL type (where applicable)

for built-in earpiece audio playback aka. "ear-friendly mode" we were using

I have installed a vanilla django-cms on a new server. I installed all requirements. It all went fine, up untill the point where I wanted to migrate to the database (Postgres).

So this is what I did :

Tried reinstalling and installing it all again. Didn't change it.
Used google to try and find people with the same error.
Try editing the signals file on which the error(shown below) fires, but that meant rewriting it all, which still made it unresponsive.

A "multiarch" Python interpreter built on MacOS is intended to target MacOS-on-Intel and MacOS-on-Apple's-arm64.

There is absolutely no binary compatibility with Linux-on-Apple's-arm64, or with Linux-on-aarch64. You can't run MacOS executables on Linux, no matter if the architecture matches or not.

ANSWER

Answered 2021-Dec-17 at 13:40

It seems you violate standad:

33.5.3 Class condition_variable [thread.condition.condvar]

void wait(unique_lock& lock);

Requires: lock.owns_lock() is true and lock.mutex() is locked by the calling thread, and either

(9.1) — no other thread is waiting on this condition_variable object or

(9.2) — lock.mutex() returns the same value for each of the lock arguments supplied by all concurrently waiting (via wait, wait_for, or wait_until) threads.

Cleary two threads are waiting and lock.mutex() does not return same.

Android Listener stop running when app in background

Asked 2021-Nov-23 at 12:48

I am developing an app where the app will detect Bluetooth signals (Sensoro Smart Beacon device) and open the activity. But I want the app to still be able to detect the signal even when the application on the background or even when killed. I used a foreground service, it detects the signal when I open the application and move between activities but when sending the app to the background and opening other applications, the listener stops although the service still working. I am printing the logs. System.out.println("Sensoro 2" ); keeps printing even when I kill the application or open another application. But the printing logs in BeaconManagerListener are not working. I tried to use background service but it didn't work also. Can you please advise if there is a way to make the listener works in a service when the app in background or killed? Here is the service code:

I looked at the Android rules and regulations page

According to Google documents, from Android 8 onwards, all applications that do not have a Google-approved signature will be removed from the background after a few minutes.

But the solutions:

The first solution is to run the application in debug mode
The second solution is to assign a signature to the application and send it to Google for approval

recommend:

The third solution is to remove the google play service application from the emulator or android phone

Android 12 - Foreground service launch restrictions

Asked 2021-Nov-06 at 20:48

I'm developing an SDK that needs to startForeground service from the background. Because it uses background location and Bluetooth-related works. If the application is killed, the monitoring is performing in the background. That's why I'm using the foreground service. There is a condition that starts the foreground service from the background.

Currently, my SDK using Service to handle this job. But Android 12 on-words it doesn't support to start service from the background.

I'm trying to start the service from the background the below exception throws.

...

ANSWER

Answered 2021-Sep-18 at 16:28

There is no one in the world that can give you an answer. The idea of all these restrictions is that we as developers need to optimize our applications. So if this is not possible for you it means most likely that you need to optimize the way you do your work. For this to happen you need to provide more info of what exactly events you are receiving, what is exactly your use case, etc.

https://developer.android.com/about/versions/12/foreground-services#cases-fgs-background-starts-allowed

As you can see there is info about exceptions for:

Your app receives a Bluetooth broadcast that requires the BLUETOOTH_CONNECT or BLUETOOTH_SCAN permissions.

But there is nothing in your question saying that your use case might relate to this.

Also, I don't understand how the app might be killed, but you keep working in the background.

Also if you want to constantly do something - why there is an event when you are in the background. Just when the user opens the app - start the service and keep it going.

You can also just "hack" it and ask the user to remove you from battery optimization.
